   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to cleaning implement. More particularly, the present invention relates to cleaning implements adapted to covers for floors or carpets, for example, and including a liquid supply device. 
   2. Related Art 
   By way of example, a cleaning implement including a liquid supply device is designed to have a cleaning head arranged at a distal end of a stem and a manual operation part arranged at a grip of the stem. A pressure-pump-type discharge container and a pump pusher are arrange at the distal end of the stem, and a coupling member for coupling the manual operating part to the pump pusher is arranged along the stem. By manual operation applied to the manual operation part, the pressure-pump-type discharge container is pressed through the coupling member and the pump pusher, discharging a solution from the discharge container to the cleaning head. Refer, for example, to Patent Document 1 (Japanese Published Unexamined Patent Application 2004-337454). 
   According to Patent Document 1, the cleaning implement allowing wet wiping is provided, which can operate quietly, discharge a solution stably, and contribute to weight reduction. 
   SUMMARY OF THE INVENTION 
   According to Patent Document 1, a solution can be sprayed forward of the cleaning head and in the vicinity thereof from a pump spray nozzle. However, when a polish or a wax is applied and wiped away on the floor, if cleaning operation is carried out in advance, an operator will step on the applied floor, raising a problem of leaving footprints, etc. on the applied floor, for example. 
   The cleaning implement constructed to spray a solution forward of the cleaning head and in the vicinity thereof sometimes raises a problem that a solution may be sprayed on interior furniture or electrical appliance. A cleaning implement may be considered that can spray a solution forward or rearward of the cleaning head by the operator&#39;s choice. This is a problem to be solved by the present invention. 
   In order to solve the above problem, an object of the present invention is to provide a cleaning implement including a cleaning head and a valve opening and closing device connected to the cleaning head and able to hold a first container receiving a first fluid or a second container receiving a second container, in which the cleaning implement can spray a solution forward or rearward of the cleaning head by operator&#39;s choice. 
   In order to achieve the above object, inventors have invented the following new cleaning implement configured such that a valve opening and closing device includes a connection mechanism from which a first container is detachable and an adaptor coupled to the connection mechanism and from which a second container is detachable, wherein a first circulation path extends to a first ejection nozzle for ejecting a first fluid from the connection mechanism to the outside of the cleaning head, and a second circulation path extends to a second ejection nozzle for ejecting a second fluid from the adapter. 
   In a first aspect of the present invention, a cleaning implement includes: a cleaning head; and a holding portion, a fluid being able to be ejected rearward of the cleaning head when using the cleaning implement by positioning the cleaning head at the front and the holding portion at the rear. 
   By way of example, the cleaning head may have a cleaning operation surface on a bottom, and the holding portion is arranged on the side opposite the cleaning head. The cleaning head and the holding portion are coupled by a pipe, for example. According to the first aspect of the present invention, when using the cleaning implement by positioning the cleaning head at the front and the holding portion at the rear, a fluid can be ejected rearward of the cleaning head. The fluid may be, for example, a second fluid as will be described later. By way of example, the cleaning implement according to the first aspect of the present invention can eject the second fluid such as polish or wax to the floor, and a user can apply the second fluid on the floor toward the rear. Thus, the user will not step on the applied floor. Moreover, since the second fluid is ejected to a space between the user and the cleaning head, the probability of spraying a solution on interior furniture or electrical appliance is reduced. 
   In a second aspect of the present invention, a cleaning implement includes: a cleaning head having a cleaning operation surface on a bottom; a holding portion arranged on the side opposite the cleaning head; a pipe that couples the cleaning head and the holding portion; and a valve opening and closing device provided to the pipe, the valve opening and closing device being able to hold one of a first container receiving a first fluid and a second container receiving a second container, the valve opening and closing device including a connection mechanism from which the first container is detachable and an adaptor coupled to the connection mechanism and from which the second container is detachable, the cleaning head including a first ejection nozzle which ejects the first fluid from the connection mechanism to the outside of the cleaning head, the adapter including a second ejection nozzle which ejects the second fluid from the adapter, the holding portion including a lever coupled to the valve opening and closing device, the lever opening and closing the first valve of the first container or the second valve of the second container, in which the first ejection nozzle can eject the first fluid forward of the cleaning head, and the second ejection nozzle can eject the second fluid rearward of the cleaning head when using the cleaning implement by positioning the cleaning head at the front and the holding portion at the rear. 
   The second aspect of the present invention includes a cleaning head having a cleaning operation surface on a bottom. Also, it includes a holding portion arranged on the side opposite the cleaning head. A pipe couples the cleaning head and the holding portion. A valve opening and closing device is provided to the pipe. The valve opening and closing device can hold a first container for receiving a first fluid or a second container for receiving a second fluid. 
   By way of example, the cleaning head may have a cleaning sheet detachably attached to the cleaning operation surface. The pipe may be a holding stem, and may be configured by connecting a plurality of pipes, for example. The valve opening and closing device may not be mounted at the position between the cleaning head and the holding portion, but at the position close to the cleaning head or at the position close to the holding portion. The valve opening and closing device is mounted, preferably, at the position close to the cleaning head. With the first and second containers, either of the two may be mounted to the valve opening and closing device without being both mounted thereto. The valves designate valves of the first and second containers. By actuation of the valve opening and closing device, the first or second fluid is ejected. 
   According to the second aspect of the present invention, the valve opening and closing device includes a connection mechanism from which the first container is detachable. It also includes an adapter coupled to the connection mechanism and from which the second container is detachable. The cleaning head includes a first ejection nozzle that ejects the first fluid from the connection mechanism to the outside of the cleaning head. The adapter includes a second ejection nozzle that ejects the second fluid from the adapter. 
   By way of example, provided to the connection mechanism are a cam device and pump as will be described later and for feeding the first fluid from the first container to the first ejection nozzle. The valve opening and closing device has a structure that allows the second container in place of the first container to be detached therefrom through the adapter. A path extending from the connection mechanism to the first ejection nozzle forms the first circulation path through which the first fluid can be ejected from the cleaning head. Furthermore, a path extending from the adapter to the second ejection nozzle forms the second circulation path through which the second fluid can be ejected from the adapter by interrupting the first circulation path. 
   According to the second aspect of the present invention, the holding portion includes a lever. The lever is coupled to the valve opening and closing device. The lever opens and closes the first valve of the first container or the second valve of the second container. 
   By way of example, as will be described layer, the holding portion includes a pulley rotated interlockingly with rotary motion of the lever. The connection mechanism includes the cam device including a rocker arm forming a dynamic articulation that reciprocates angularly and a pusher following the rocker arm to reciprocate linearly. When the lever is coupled to the valve opening and closing device, the belt may have one end caught at a moving end of the rocker arm and the other end wound on the pulley so as to transmit a displacement of the lever to the pusher. By interlocking the adaptor with displacement motion of the pusher, the second valve of the second container is opened and closed, for example. 
   According to the second aspect of the present invention, when using the cleaning implement by positioning the cleaning head at the front and the holding portion at the rear, the first ejection nozzle can eject the first fluid forward of the cleaning head, and the second ejection nozzle can eject the second fluid rearward of the cleaning head. 
   By way of example, the first fluid may be water, a liquid detergent or a liquid wax, and the second fluid may an atomized wax or a foamed wax. By operating the lever, the second fluid is ejected from the spout of the second ejection nozzle. The term “when using” may be, for example, a state while the cleaning head is placed on the floor, the holding portion is held by user&#39;s hands, and the pipe is operated at an angle of inclination of about 45 degrees. The first ejection nozzle can eject the first fluid forward of the cleaning head, or the second ejection nozzle can eject the second fluid rearward of the cleaning head. The second fluid may be ejected to a space between the cleaning head and the user. The second fluid is ejected in the direction substantially parallel to the pipe, for example. The second fluid is ejected, preferably, in the range of an open angle of plus or minus 20 degrees with respect to the direction substantially parallel to the pipe. The wording “ejected” includes a case in which the second fluid is diffused like a fine spray. 
   Thus, the cleaning implement according to the second aspect of the present invention is a cleaning implement including a cleaning head and a valve opening and closing device connected to the cleaning head and being able to hold a first container receiving a first fluid or a second container receiving a second container, in which the cleaning implement can spray a solution forward or rearward of the cleaning head by operator&#39;s choice. 
   The valve opening and closing device includes a connection mechanism from which a first container is detachable and an adaptor coupled to the connection mechanism and from which a second container is detachable, in which a first circulation path extends to a first ejection nozzle for ejecting a first fluid from the connection mechanism to the outside of the cleaning head, and a second circulation path extends to a second ejection nozzle for ejecting a second fluid from the adapter. 
   By way of example, the cleaning implement according to the second aspect of the present invention can eject the second fluid such as polish or wax from the second ejection nozzle to the floor, and the user can apply the second fluid on the floor toward the rear. Thus, the user will not step on the applied floor. Moreover, since the second fluid is ejected from the second ejection nozzle to a space between the user and the cleaning head, the probability of spraying a solution on interior furniture or electrical appliance is reduced. 
   In a third aspect of the present invention, a cleaning implement according to the second aspect of the present invention has a second ejection nozzle that includes a spout to eject the second fluid in the direction substantially parallel to the pipe. 
   A spout of the second ejection nozzle is arranged, for example, at a position away from the pipe by a predetermined distance so as to eject the second fluid toward the floor. The wording “eject the second fluid in the direction substantially parallel to the pipe” includes ejection in the range of a predetermined open angle with respect to the direction substantially parallel to the pipe. The predetermined open angle is, preferably, in the range of plus or minus 20 degrees. The second fluid is ejected from the second ejection nozzle toward the floor in accordance with operation of the lever. 
   In a fourth aspect of the present invention, a cleaning implement according to the second or third aspect of the present invention has a connection mechanism connected to the first valve of the first container. 
   According to the fourth aspect of the present invention, since the first valve of the first container is operated directly, the mechanism of the cleaning implement can be simplified, resulting in cost reduction of the cleaning implement. 
   In a fifth aspect of the present invention, a cleaning implement according to any one of the second to fourth aspect of the present invention has a first container that is of a type of a bottle, the bottle being moved in the direction parallel to an axis of the first valve so as to drop the first fluid naturally. 
   According to the fifth aspect of the present invention, the first container can be of a type of a bottle which is commercially available. The first container ensuring natural dropping of the first fluid suitable for cleaning can be mounted to the cleaning implement. 
   In a sixth aspect of the present invention, a cleaning implement according to any one of the second to fifth aspects of the present invention has a second ejection nozzle connected to the second valve of the second container. 
   According to the sixth aspect of the present invention, since the second ejection nozzle is directly connected to the second valve, the mechanism of the cleaning implement can be simplified, resulting in cost reduction of the cleaning implement. 
   In a seventh aspect of the present invention, a cleaning implement according to any one of the second to sixth aspects of the present invention has a second container that is a tilt-type spray can, the tilt-type spray can being tilted in the direction orthogonal to an axis of the second valve so as to eject the second fluid. 
   According to the seventh aspect of the present invention, since a tilt-type spray can for receiving a polish or a wax suitable for application on the floor can be mounted to the cleaning implement, for example, the second fluid suitable for application on the floor can be used easily. 
   In an eighth aspect of the present invention, a cleaning implement according to any one of the second to seventh aspects of the present invention has a connection mechanism that includes a cam device including a rocker arm forming a dynamic articulation that reciprocates angularly and a pusher following the rocker arm to reciprocate linearly, the holding portion including a pulley rotated interlockingly with rotary motion of the lever and a belt having one end caught at a moving end of the rocker arm and the other end wound on the pulley, the belt transmitting a displacement of the lever to the pusher. 
   According to the eighth aspect of the present invention, the belt may be used as a means for transmitting motion of the lever of the holding portion to the rocker arm of the connection mechanism, providing excellent flexibility. Thus, even if an articulation part exists between the holding portion and the connection mechanism, motion of the lever of the holding portion can surely be transmitted to the rocker arm. 
   In a ninth aspect of the present invention, a cleaning implement according to the eighth aspect of the present invention has an adaptor that includes a cylindrical adaptor main body, a cylinder held inside the adaptor main body to be movable axially and the second ejection nozzle coupled to the cylinder, the adaptor main body having one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container, the cylinder having one end abutting on a distal end of the pusher toward the first connection port and the other end having an inclined portion that intersects the axial direction of the cylinder at an acute angle toward the second connection port, in which the second ejection nozzle is formed in a T-shape, the T-shaped second ejection nozzle having one end coupled to the inclined portion and the other end connected to the second valve, the T-shaped second ejection nozzle having a spout at a T-shaped end for ejecting the second fluid to the outside of the adaptor main body. 
   According to the ninth aspect of the present invention, the adapter includes a cylindrical adapter main body. It also includes a cylinder movably held inside the adaptor main body to be movable axially. It further includes the second ejection nozzle coupled to the cylinder. The adaptor main body has one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container. 
   According to the ninth aspect of the present invention, the cylinder has one end abutting on a distal end of the pusher toward the first connection port and the other end having an inclined portion that intersects the axial direction of the cylinder at an acute angle toward the second connection port. The second ejection nozzle is formed in a T-shape. The T-shaped second ejection nozzle has one end coupled to the inclined portion and the other end connected to the second valve. The T-shaped second ejection nozzle has a spout at a T-shaped end for ejecting the second fluid to the outside of the adaptor main body. 
   A weight reduction can be achieved, for example, by molding out of a synthetic resin the adapter main body, cylinder, and second ejection nozzle that are components of the adapter. The adapter may be mounted to the valve opening and closing device in place of the first container. When operating the lever, movement of the pusher is transmitted to the cylinder. When the cylinder is moved, the inclined portion at the other end of the cylinder operates to tilt the second ejection nozzle. The second fluid is supplied from the second container to the second ejection nozzle. On the other hand, when releasing the lever, the pusher returns to the position, and the cylinder returns to the pusher side interlockingy with returning of a tilting posture of the second ejection nozzle. While the cylinder reciprocates, an angle of the inclined portion is, preferably, in the range of 30 to 60 degrees. Thus, the cleaning implement of the present invention can eject the second fluid as appropriate by operating the lever. 
   In a tenth aspect of the present invention, a cleaning implement according to the ninth aspect of the present invention has a cylinder that includes a pair of side walls arranged on both sides of the inclined portion with a space, the second valve having a part arranged in the space. 
   A distal end of the second valve is coupled by being restrained by the pair of side walls. 
   In an eleventh aspect of the present invention, a cleaning implement according to the eighth aspect of the present invention has an adaptor that includes a cylindrical adaptor main body, a cylinder held inside the adaptor main body to be movable axially and the second ejection nozzle coupled to the cylinder, the adaptor main body having one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container, in which the second ejection nozzle includes an L-shaped portion and a collar formed with the L-shaped portion and extending in the direction orthogonal to the axis of the second valve, the cylinder having one end abutting on a distal end of the pusher toward the first connection port and the other end having a protrusion that can push the collar in a position distant from the second valve, the L-shaped portion having a first end coupled to the second valve and a second end formed with a spout for ejecting the second fluid to the outside of the adaptor main body. 
   According to the eleventh aspect of the present invention, the adaptor includes a cylindrical adaptor main body. It also includes a cylinder held inside the adaptor main body to be movable axially. It further includes the second ejection nozzle coupled to the cylinder. The adaptor main body having one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container. 
   According to the eleventh aspect of the present invention, the second ejection nozzle includes an L-shaped portion and a collar formed with the L-shaped portion and extending in the direction orthogonal to the axis of the second valve. The cylinder has one end abutting on a distal end of the pusher toward the first connection port and the other end having a protrusion that can push the collar in a position distant from the second valve. The T-shaped portion has one end coupled to the second valve and the other end formed with a spout for ejecting the second fluid to the outside of the adaptor main body. 
   According to the eleventh aspect of the present invention having a structure different from that of the eighth aspect of the present invention, the second ejection nozzle is tilted based on this principle. 
   The cleaning implement according to the present invention is a cleaning implement including a cleaning head and a valve opening and closing device connected to the cleaning head and being able to hold a first container receiving a first fluid or a second container receiving a second container, in which the cleaning implement can spray a fluid forward or rearward of the cleaning head by operator&#39;s choice. 
   By way of example, the cleaning implement according to the present invention can eject the second fluid such as polish or wax from the second ejection nozzle to the floor, and the user can apply the second fluid on the floor toward the rear. Thus, the user will not step on the applied floor. Moreover, since the second fluid is ejected from the second ejection nozzle to a space between the user and the cleaning head, the possibility of spraying a solution on an interior furniture or electrical appliance becomes lower.

   Referring to  FIG. 4 , a liquid ejecting portion  20  is mounted on the holder  24 . The liquid ejecting portion  20  is arranged between the right end face  2   c  and the left end face  2   d  of the holder  24  and in front of the universal joint  21 . The liquid ejecting portion  20  includes a base  27  and the first ejection nozzle  23  arranged on the base  27 . The base  27  and first ejection nozzle  23  are injection molded out of a synthetic resin such as ABS, PP, PET or the like. The first ejection nozzle  23  is fixed on the base  27  by fixing means such as fitting, bonding or screwing. The base  27  and the first ejection nozzle  23  of the liquid ejecting portion  20  may be formed integrally. 
   Referring to  FIG. 4 , a recess  24   a  that opens toward the front face  2   a  is formed in the top face of the holder  24  between the right end face  2   c  and the left end face  2   d . The universal joint  21  is engaged in the recess  24   a . The liquid ejecting portion  20  is arranged in the recess  24   a . At a position reasonably distant from the cleaning operation surface  22  toward the height direction, the liquid ejecting portion  20  can eject a first fluid as will be described later from a spout  23  of the first ejection nozzle  23  forward outward of the cleaning head  2 . 
   Referring to  FIG. 6 , the holding portion  7  is provided to the pipe  8  on the opposite side of the cleaning head  2 , and is formed by assembling two holding casings  7   b . The holding portion  7  is coupled to the valve opening and closing device  3 , and includes a lever  71  for opening and closing a first valve  93  (refer to  FIG. 10 ) of the first container  61  or a second valve  62   a  (refer to  FIG. 21 ) of a second container  62  as will be described later. 
   Referring to  FIG. 6  or  7 , the lever  71  is supported to the holding portion  7  to be rotatable about a pivot  7   c  formed with the holding portion  7 . Referring to  FIG. 8 , in order to allow an user to pull the lever  71  by an angle γ, part of the lever  71  protrudes outward from the inside of the holding portion  7  by a biasing force of a torsion coil spring  75  arranged in the holding portion  7 . 
   A gear  71   a  having the pivot  7   c  as center of a pitch circle is partly formed with the lever  71 . A pulley  74  is assembled to be rotatable about a pivot  7   d  formed with the holding portion  7 . A gear  74   a  having the pivot  7   d  as center of rotation is assembled to the pulley  7 . 4 . When the lever  71  is pulled, the gear  71   a  meshes with the gear  74   a . Normally, the gear  71   a  does not mesh with the gear  74   a . A spiral coil spring (not shown) is built in the pulley  74 . Referring to  FIG. 6  or  7 , the spiral coil spring operates to rotate the pulley  74  having one end of a belt  73  wound thereon in the direction of winding the belt  73 . 
   Referring to  FIG. 7  or  8 , when the user does not pull the lever  71 , the pulley  74  winds the belt  73  by a winding force of the spiral coil spring, always providing a predetermined tension to the belt  73 . When the user pulls the lever  71 , the gear  71   a  meshes with the gear  74   a  so that the pulley  74  can wind the belt  73  by a force produced by pulling the lever  71  and a tension of the spiral coil spring. 
   Referring to  FIGS. 1 and 2 , the pipe  8  is provided with the valve opening and closing device  3  between the cleaning head  2  and the holding portion  7  and on the side that the user is situated. Referring to  FIG. 9  or  10 , the valve opening and closing device  3  includes a connection mechanism  31  and a cam device  33 . The connection mechanism  31  renders the first container  61  detachable. The connection mechanism  31  is covered with a cover  31   c  for facilitating attachment and detachment of the first container  61 . The cam device  33  is composed of a rocker arm  34  forming a dynamic articulation that reciprocates angularly and a pusher  35  following the rocker arm  34  to reciprocate linearly. The pusher  35  is formed out of a synthetic resin and is mounted in a pump  36 . 
   The pump  36  has a shape having a U-shaped section with one end opened. An opening  36   a  at one end of the pump  36  is hermetically connected to a frame  31   a  of the connection mechanism  31 . A hole  36   b  is formed at the other end (bottom) of the pump  36 . The hole  36   b  is hermetically connected to one end of a hose  4  that defines a first circulation path. The other end of the hose  4  is hermetically connected to the first ejection nozzle  23  through the inside of the pipe  8 . 
   Referring to  FIG. 9  or  10 , the pusher  35  includes a distal end  35   a  that abuts the first valve  93  and a collar  35   b  that closes the hole  36   b  of the bottom of the pump  36 . A ring  35   c  mounted to the bottom of the pump  36  makes sliding contact with a convex  34   b  of the rocker arm  34 . The distal end  35   a  and the collar  35   b  are both positioned inside the pump  36 , whereas the ring  35   c  is positioned outside the pump  36 . The collar  35   b  and the ring  35   c  hold the pump  36  therebetween. The collar  35   b  closes the hole  36   b  by a resilient force of the pump  36  toward the hole  36   b . The distal end  35   a  protrudes toward the opening  36   a.    
   The rocker arm  34  reciprocates angularly with a pivot  31   b  provided to the frame  31   a  as center of rotation. The other end  73   a  of the belt  73  is caught at a moving end  34   a  of the rocker arm  34 . Therefore, the belt  73  extending from the pulley  74  passes through the inside of the pipe members Bb to  8   d  to be caught at the moving end  34 . The convex  34   b  (refer to  FIG. 9 ) is formed with the rocker arm  34 . The convex  34  protrudes from the middle of the rocker arm  34  toward the ring  35   c  so as to be capable of making sliding contact with the ring  35   c.    
   Referring to  FIG. 10 , the first container  61  includes a tank  61   b  for receiving the first fluid and a cap  90  mounted to an opening of the tank  61   b . A valve hole  91   a  is formed at a distal end of the cap  90 . 
   The internal structure of the cap  90  will be described. As shown in  FIG. 11 , the cap  90  includes a cap main body  91 , a first ring member  92 , a first valve  93 , a compression coil spring  94 , a second ring member  95 , a valve housing  96 , a seal member  97 , a tube member  98 , a valve protection member  99 , and a valve member  100 . 
   As shown in  FIGS. 12A to 12C , the cap main body  91  includes a distal end  91   b , a mesh portion  91   c , and an air hole  91   d . The valve hole  91   a  is arranged at one end of the distal end  91   b . The distal end  91   b  accommodates the first ring member  92 , the first valve  93 , the compression coil spring  94 , the second ring member  95 , the valve housing  96 , and the seal member  97 . The mesh portion  91   c  is formed with a mesh groove that meshes with the opening of the tank  61   b . The air hole  91   d  is arranged in a substantially flat surface arranged on the top of the mesh portion  91   c.    
   The first ring member  92  includes a circular ring packing. The first ring member  92  seals the first fluid charged in the first container  61 . The first valve  93  includes a head  93   a  and a leg  93   b . The head  93   a  includes a cylindrical head main body and a pair of flanges arranged on both sides of the head main body. The first ring member  92  is arranged between the flanges, i.e., on the peripheral face of the head main body. One end of the head  93   a  is formed with an insertion hole into which one end of the pusher  35  is inserted. The other end of the head  93   a  is formed with the leg  93   b . The leg  93   b  includes four blades. Each blade is formed with a convex for catching the compression coil spring  94 . One end of the compression coil spring  94  is caught in a catch groove  96   e  as will be described later. On the other hand, the other end of the compression coil spring  94  is caught at the convex. 
   As shown in  FIGS. 13A to 13C , the valve housing  96  includes a valve housing main body  96   h , a slide hole  96   a  through which the first valve  93  slides, a flange  96   b , and a long tube  96   c  engaged with the tube member  98 . The slide hole  96   a  includes a first slide hole  96   a ′ and a second slide hole  96   a ″ that have different diameters. The catch groove  96   e  is arranged between the first and second slide holes  96 ′ and  96 ″. An opening  96   f  forming the first slide hole  96   a ′ is engaged with the cap main body  91 . The second ring member  95  is arranged between the opening  96   f  and the flange  96   b . The second ring member  95  includes a circular ring packing. The long tube  96   c  is arranged at the side of the other opening  96   g  forming the second slide hole  96   a ″ and on the flange  96   b . The long tube  96   c  includes an air hole  96   d . Two convexes  96   i  are arranged on the flange  96   b  on the side having the long tube  96   c.    
   The seal member  97  includes a flange  97   a  as shown in  FIG. 11 . The flange  97   a  has a diameter greater than that of the flange  96   b  of the valve housing  96 . The seal member  97  includes in substantially the center a through hole  97   b  through which the opening  96   g  is arranged. The long tube  96   c  and the convexes  96   i  are arranged through the seal member  97 . The seal member  97  is formed out of a silicone resin. 
   The tube member  98  has a columnar shape. The section of the tube member  98  is shaped like a ring to allow air from the air hole  91   d  to flow into the tank  61   b . One end of the tube member  98  is engaged with the long tube  96   c . The tube member  98  is formed out of polyurethane (PU) resin. The valve protection member  99  is shaped like a bell. A horn portion  99   a  having an apex as engaged is arranged at an upper end of the valve protection member  99 . The horn portion  99   a  is engaged with the other end of the tube member  98 . The top of the valve protection member  99  includes a pair of recesses  99   b . A convex (not shown) having a through hole engaging with the valve member  100  is arranged in the valve protection member  99 . The valve member  100  is arranged in the valve protection member  99 . 
   The valve member  100  includes a valve main body  100   a  and a flange  100   b . The valve main body  10   a  is shaped substantially cylindrically. The valve main body  10   a  is formed out of a resilient member. A distal end  100   c  of the valve main body  10   a  has a cut shape obtained by cutting the cylindrical shape from both side faces thereof. It is noted that the cut shape is such that two plate-shaped valves are arranged to be superimposed one upon another at the distal end, and are constructed to open or close in substantially the center of the distal end. With such a construction, the distal end  100   c  allows the valves to open in substantially the center so that air from the air hole  91   d  is fed to the tank  61   b  through the tube member  98 . A flange  100   b  is arranged at the other end of the valve main body  100   a.    
   With the above structure, the first valve  93  is biased by the compression coil spring  94  from the inside of the cap  90 , thereby obtaining the closed state of the valve hole  91   a.    
   When the first container  61  is mounted to the connection mechanism  31 , the outer periphery of the cap  90  makes close contact with the pump  36  hermetically, whereas the first valve  93  of the first container  61  is pressed to the distal end  35   a  against a biasing force of the compression coil spring  94 . At this time, the first valve  93  of the first container  61  is slightly moved toward the tank  61   b . However, no clearance allowing part of the first fluid received in the first container  61  to flow out toward a space defined by the pump  36  and the first valve  93  is formed between the first valve  93  and the valve hole  91   a.    
   As a result, part of the first fluid received in the first container  61  does not flow out toward a space defined by the pump  36  and the first valve  93 . Moreover, since the hole  36   b  is closed by the pump  36  and the pusher  35 , the first fluid in the first container  61  is not moved into the hose  4  in this state. 
   On the other hand, when the user pulls the lever  71 , the belt  73  is moved to the holding portion  7  so that the rocker arm  34  is rotated by a pulling force of the belt  73 . Furthermore, since the pusher  35  is linearly moved to the holding portion  7 , the first valve  93  of the first container  61  is moved in the direction of the tank  61   b , and the collar  35   b  is moved in the direction of separating from the hole  36   b  of the pump  36 . Therefore, concurrently with a clearance being produced between the collar  35   b  and the hole  36   b , air taken in from the air hole  91   d  is supplied into the tank  61   b  through the tube member  98  and the valve member  100 . With this, the first fluid in the first container  61  is supplied to the first ejection nozzle  23  through this clearance and the hose  4 . The supplied first fluid is ejected forward of the cleaning head  2  from the first ejection nozzle  23 . That is, the first fluid passes through the first circulation path. 
   Referring to  FIG. 14 , the valve opening and closing device  3  allows mounting of the second container  62  through an adaptor  32  in place of the first container  61 . The adaptor  32  includes a cylindrical adaptor main body  32   a , a cylinder  32   b  axially movably held in the adaptor main body  32   a , and a second ejection nozzle  51  coupled to the cylinder  32   b . The second ejection nozzle  51  serves as a second circulation path through which a second fluid flows. 
   Referring to  FIG. 15 , the adaptor main body  32   a  includes at one end a convex  321  of substantially the same shape as that of the cap  90  of the first container  61 . Referring to  FIG. 14 , a first connection port  32   c  having a size that allows non-contact entry and retraction of the distal end  35   a  of the pusher  35  is formed in the center of the convex  321 . Referring to  FIG. 20 , the other end of the adaptor main body  32   a  is formed with a second connection port  32   d  that holds detachably the second container  62 . An opening  32   g  (refer to  FIG. 19 ) is formed in the side face of the adaptor main body  32   a  on the side of the second connection port  32   d  so as to arrange a spout  51   c  of the second ejection nozzle  51  outside the adaptor main body  32   a . Referring to  FIG. 24 , the spout  51   c  is positioned, preferably, at a distance in the range of about 50 to 80 cm from the cleaning operation surface  22  (refer to  FIG. 3 ), and more preferably, at a distance of about 70 cm from the cleaning operation surface  22 . Therefore, as shown in  FIG. 24 , in the state in which the cleaning implement  10  is used by being inclined at an angle of about 45 degrees, for example, a height H of the spout  51   c  from a floor surface F can be in the range of 40 to 60 cm from the floor surface, and more preferably, about 50 cm. 
   Referring to  FIG. 18 , a collar  323  extending in the direction orthogonal to an axis of the cylinder  32   b  is formed at one end of the cylinder  32   b . Referring to  FIG. 21 , the other end of the cylinder  32   b  includes an inclined portion  32   e  that intersects the axial direction at an acute angle toward the second connection port  32   d . An intersection angle of the axial direction and the inclined portion  32   e  is, preferably, in the range of 30 to 60 degrees. The cylinder includes a pair of side walls  32   f  arranged on both sides of the inclined portion  32   e  with a space. Referring to  FIG. 20 , a collar  324  that can abut on a step  325  from inside is integrally formed with the center of the cylinder  32   b.    
   Referring to  FIG. 16  or  17 , the second ejection nozzle  51  includes a main-body portion  511  and a nozzle portion  512 . The second ejection nozzle  51  is formed in a T-shape by assembling the main-body portion  511  and the nozzle portion  512 . Referring to  FIG. 16  or  21 , one end  51   a  of the main-body portion  511  makes contact with the inclined portion  32   e . The other end  51   b  of the main-body portion  511  is connected to the second valve  62   a . A connection end  51   e  of the main-body portion  511  is connected to the nozzle portion  512 . Referring to  FIG. 17 , the spout  51   c  for ejecting the second fluid is arranged at a T-shaped end of the T-shaped second ejection valve  51  in a position outside the adaptor main body  32   a . Part of the second valve  62   a  is arranged in the space of the pair of side walls  32   f.    
   Referring to  FIG. 14 , the cylinder  32   b  and the second ejection nozzle  51  are accommodated in the adaptor main body  32   a  from the second connection port  32   d . Since one end of the adaptor main body  32   a  has substantially the same shape as that of the cap  90  of the first container  61 , one end of the adaptor main body  32   a  is engaged with the pump  36  of the connection mechanism  31  so that the adaptor main body  32   a  is held by the connection mechanism  31 . At this time, the spout  51   c  protrudes from the opening  32   g  (refer to  FIG. 19 ). The spout  51   c  protrudes from the opening  32   g  so as to allow ejection backward or opposite of the first ejection nozzle  23  in the front and back direction of the cleaning head  2 . 
   The second container  62  is mounted to the adaptor main body  32   a  on the side of the second connection port  32   d . The second container  32  is a spray can including a tilt-type valve that is tilted in the direction orthogonal to an axis of the second valve  62   a  so as to eject the second fluid received in the second container  62 . Therefore, when the second ejection nozzle  51  is tilted, the second fluid is ejected from the spout  51   c . Moreover, since the spout  51   c  is positioned at the height H from the floor surface F, the second fluid ejected from the spout  51   c  may be a fluid of lower viscosity such as water as well as a fluid of higher viscosity such as foam. 
   By way of example, the first container  61  may be of a type of a bottle that is moved in the direction parallel to an axis of the first valve  93  (refer to  FIG. 10 ) so as to drop the first fluid naturally. By way of example, the first fluid includes water, a liquid detergent or a liquid wax. The second fluid includes a polish such as a synthetic wax that becomes solid at room temperatures after drying such as acryl resin wax or polyethylene wax or a natural wax such as Carnauba wax. Adoption of such a wax or polish facilitates coating or wiping on the floor surface. 
   When the user pulls the lever  71 , the lever  71  is pushed into the holding portion  7  against a biasing force of the torsion coil spring  75 , rotating the gear  71   a . With this, the gear  74   a  is rotated together with the pulley  74  to wind the belt  73 . When the belt  73  is wound on the pulley  74 , the pusher  35  moves the cylinder  32   b  to the second container  62 . 
   When the cylinder  32   b  is moved to the second container  62 , the inclined portion  32   e  tilts the second ejection nozzle  51  in the direction of orthogonal to the moving direction of the cylinder  32   b . With this, referring to  FIG. 24 , the second fluid in the second container  62  can be ejected backward of the cleaning head  2  from the spout  51   c  of the second ejection nozzle  51 . 
   When the user stops pulling the lever  71 , the lever  71  rotates the pulley  74  in the direction of loosing the belt  73  by a biasing force of the torsion coil spring  75 . With this, the pusher  35  is moved in the direction away from the cylinder  32   b , providing no force of pushing the cylinder  32   b . Furthermore, a returning force of the second valve  62   a  of the second container  62  acts on the inclined portion  32   e  of the cylinder  32   b . Then, the cylinder  32   b  is moved in the direction away from the second container  62 . Thus, the inclination of the second valve  62   a  with respect to the second container  62  returns to the vertical state, stopping ejection of the second fluid from the second ejection nozzle  51 . 
   In another embodiment as shown in  FIGS. 22 and 23 , the second ejection nozzle  51  includes an L-shaped portion  51   h  and a collar  51   f  formed with the L-shaped portion  51   h  and extending in the direction orthogonal to the axis of the second valve  62   a . The other end of the cylinder  32   b  includes a protrusion  32   h  that can push the collar  51   f  in the position away from the second valve  62   a . The L-shaped portion  51   h  has one end coupled to the second valve  62   a , and the other end formed with the spout  51   c  for ejecting the second fluid to the outside position of the adaptor main body  32   a.    
   The surface with which the protrusion  32   h  makes contact is separated from a center P of rotation on which the second valve  62   a  tilts by a distance h in the axial direction. The protrusion  32   h  makes contact with the collar  51   f  spaced with respect to the second valve  62   a  in the direction away from the axial direction. As a result, reciprocation of the cylinder  32   b  is converted into rotation with the center P of rotation as center so that the second valve  62   a  is tilted by this rotation by an angle α. 
   In still another embodiment as shown in  FIG. 25 , the valve opening and closing device  3  allows mounting of a third container  63  through an adaptor  120  in place of the first container  61 . The third container  63  is a spray can including a tilt-type valve that is tilted in the direction orthogonal to an axis of a third valve  63   a  so as to eject a third fluid received in the third container  63 . In this embodiment, the third container  63  contains the third fluid such as wax. 
   The adaptor  120  includes a cylindrical adaptor main body  130 , a cylinder  140  axially movably held in the adaptor main body  130 , and a third ejection nozzle  150  coupled to the cylinder  140 . The third ejection nozzle  150  serves as a third circulation path through which the third fluid flows. 
   Referring to  FIG. 25 ,  26  or  27 , the adaptor main body  130  includes a cylindrical main-body portion  131 , a convex  132  arranged at one end of the main-body portion  131  and having substantially the same shape as that of the cap  90  of the first container  61 , a third connection port  133  arranged at the other end of the main-body portion  131  and for holding detachably the third container  63 , and an opening  134  arranged in the vicinity of the third connection port  133  and for leading a third ejection nozzle  150  from the cylindrical inside to the outside of the adaptor main body  130 . 
   A fourth connection port  135  having a size that allows non-contact entry and retraction of the distal end  35   a  of the pusher  35  is formed in the center of the convex  132 . The fourth connection port  135  is connected to a cylindrical inner surface  136  of the main-body portion  131 . The cylindrical inner surface  136  is connected to the opening  134 . A groove is formed in the cylindrical inner surface  136  that extends axially. 
   Referring to  FIG. 27 ,  28  or  29 , the cylinder  140  includes a cylinder main body  141  obtained by combining plate-shaped members  141   a  in the shape of a cross, a collar  142  formed at one end of the cylinder main body  141 , a collar  144  formed through a support  143  formed with the collar  142  and having a smaller diameter than the collar  142 , a collar  146  formed through a support  145  formed with the collar  144 , a collar  147  formed at the other end of the cylinder main body  141 , and a pair of pressing portions  148   a  and  148   b.    
   The pair of pressing portions  148   a  and  148   b  each have a substantially triangular shape with an apex positioned offset with respect to the center, and are formed with the collar  147  with a clearance therebetween that allows arrangement of the third ejection nozzle  150  (refer to  FIG. 26 ). The collar  144  has a shape that allows contact with the step  137  of the adaptor main body  130  from inside. The collar  142  has a shape that allows sliding on the cylindrical inner surface  136  of the adaptor main body  130 . 
   Referring to  FIG. 30 ,  31  or  32 , the third ejection nozzle  150  includes a main body  151 , an arm  152 , and a nozzle portion  153 . The main body  151  is formed in a T-shape obtained by two pipe-shaped portions  151   a  and  151   b  intersecting each other substantially orthogonally. Collars  154   a  and  154   b  extend from one end of the pipe-shaped portion  151   b . A groove  151   d  extending axially is formed in the inner peripheral surface of the pipe-shaped portion  151   a.    
   A fit hole  151   f  that can fit with the third valve  63   a  of the third container  63  is formed at an end of pipe-shaped portion  151   b . The fit hole  151   f  is connected to a through hole  151   e  that passes through the main body  151 . One opening of the through hole  151   e  is formed with a fit portion  151   c  that can fit with a fit portion  152   h  of the arm  152 . The arm  152  is formed in a roughly L-shape obtained by two pipe-shaped portions  152   a  and  152   b  intersecting each other, and has a through hole  152   g . A convex  152   e  (refer to  FIG. 30 ) is formed on the outer peripheral surface of the pipe-shaped portion  152   a . An end of the pipe-shaped portion  152   a  includes fit portion  152   h  that fits with the pipe-shaped portion  151   a  so that the convex  152   e  fits in the groove  151   d . With this, the pipe-shaped portion  152   a  and the pipe-shaped portion  151   a  ensure a relative positional relationship, and allow hermetic connection between the through hole  151   e  and the through hole  152   g.    
   A ring-shaped convex  152   f  is formed on the circumference of an end of the pipe-shaped portion  152   b . A concave  152   d  is formed in the pipe-shaped portion  152   a  on the side of the pipe-shaped portion  152   b.    
   Referring to  FIG. 33 , the nozzle portion  153  includes a nozzle main body  153   a  having a hollow pipe-shaped through hole  153   e  and a spout  153   d  formed at one end thereof and connected to the through hole  153   e . The other end of the nozzle main body  153   a  is open to form a fit opening  153   b . A convex  153   c  that can fit in the concave  152   d  is formed on part of the circumference of the fit opening  153   b . A groove  153   c  that can fit with the convex  152   f  is formed in the center of the fit opening  153   b . With this, the nozzle portion  153  ensures a relative positional relationship with respect to the arm  152 , and allows hermetic connection between the through holes  152   g  and  153   e  of the arm  152 . 
   Referring to  FIG. 31 , the third ejection nozzle  150  provides hermetic connection from the third valve  63   a  of the third container  63  to the spout  153   d , forming a third circulation path. Therefore, liquid, such as wax, which is ejected from the third valve  63   a , can be ejected from the spout  153   d.    
   Referring to  FIG. 25  or  26 , the cylinder  140  is accommodated into the adaptor main body  130  from the third connection port  133 . The cylinder  140  is maintained in the state in which the collars  142  and the collar  147  are slidable axially on the cylindrical inner surface  136 . The cylinder  140  includes plate-shaped member  141   a  extending axially, and is slidably arranged in a groove (not shown) formed in the cylindrical inner surface  136 . With this, the cylinder  140  is placed on the cylindrical inner surface  136  in the state of being movable axially, but not rotatable with the axial direction as center of rotation. The collar  146  of the cylinder  140  is positioned in the vicinity of the connection port  135  (refer to  FIG. 27 ). 
   The fit hole  151   f  of the third ejection nozzle  150  assembled by the main body  151 , arm  152 , and nozzle portion  153  is hermetically fitted with the third valve  63   a  of the third container  63  (refer to  FIG. 31 ). 
   Referring to  FIG. 31 , the third container  63  is fitted and held in the third connection port  133  of the adaptor main body  130 . At this time, the spout  153   d  of the third ejection nozzle  150  protrudes from the opening  134 . The third ejection nozzle  150  protrudes from the opening  134  so as to allow ejection backward or opposite of the first ejection nozzle  23  in the front and back direction of the cleaning head  2 . 
   Since one end of the adaptor main body  130  has substantially the same shape as that of the cap  90  of the first container  61 , it can be fitted in the pump  36  of the connection mechanism  31  so that the adaptor main body  130  is held by the connection mechanism  31 . 
   Referring to  FIG. 34 , the apexes of the pair of pressing parts  148   a  and  148   b  of the cylinder  140  are arranged in the position where they can push the collars  154   a  and  154   b  (refer to  FIG. 25  or  26 ). 
   When the user pulls the lever  71 , the lever  71  is pushed into the holding portion  7  against a biasing force of the torsion coil spring  75 , rotating the gear  71   a . With this, the gear  74   a  is rotated together with the pulley  74  to wind the belt  73 . When the belt  73  is wound on the pulley  74 , the pusher  35  pushes the convex  146   a  formed in the collar  146  of the cylinder  140 , moving the cylinder  140  to the third container  63 . 
   Referring to  FIG. 34 , when the cylinder  149  moves to the third container  63 , each of the pair of pressing parts  148   a  and  149   b  presses the collar  154   a  and  154   b  respectively. Then, the pair of pressing parts inclines the third valve  63   a . With this, the third liquid which is in the third container  63  can be ejected from the spout  153   d  of the third ejection nozzle  150  backward of the cleaning head  2 . 
   Therefore, referring to  FIG. 33 , when the third ejection nozzle  51  is tilted, the third fluid is ejected from the spout  153   d . Moreover, since the spout  153   d  is positioned at the height H from the floor surface F, the third fluid ejected from the spout  153   d  may be a fluid of lower viscosity such as water as well as a fluid of higher viscosity such as foam. Specifically, the spout  153   d  is positioned, preferably, at a distance in the range of about 50 to 80 cm from the cleaning operation surface  22  (refer to  FIG. 35 ), and more preferably, at a distance of about 70 cm from the cleaning operation surface  22 . Therefore, in the state in which the cleaning implement  10  is used by being inclined at an angle of about 45 degrees, for example, the height H of the spout  153   d  from the floor surface F can be in the range of 40 to 60 cm from the floor surface F, and more preferably, about 50 cm. 
   Referring to  FIG. 35 , when adopting the pipe  8  of 1145 mm length, an angle of 60 degrees between the pipe  8  and the floor surface F, and the third container  63  with a tilt-type valve, trial calculation is made about the minimum ejection area and maximum ejection area of a wax ejected from the spout  153   d  of the third ejection nozzle  150 . The results of trial calculation are given by points P 3  and P 4 . In this case, the minimum designates a state in which the third valve  63   a  of the aerosol can (third container  63 ) with a tilt-type valve just begins to open when a force of pulling the lever is 20N, whereas the maximum designates a state in which the third valve  63   a  opens maximally when a force of pulling the lever  71  is 24N. 
   In the drawing, points P 1  and P 2  correspond to the case in which an angle between the floor F and the pipe  8  is 45 degrees. The point P 1  designates a content landing point when pulling the lever  71  slightly so that the third valve  63   a  just begins to open, whereas the point P 2  designates a content landing point when pulling the lever  71  maximally so that the third valve  63   a  opens to the maximum extent. 
   When the user stops pulling the lever  71 , the lever  71  rotates the pulley  74  in the direction of loosening the belt  73  by a biasing force of the torsion coil spring  75 . With this, the pusher  35  is moved in the direction away from the cylinder  140 , providing no force of pushing the cylinder  140 . Furthermore, a returning force of the third valve  63   a  of the third container  63  acts on the pair of pressing portions  148   a  and  148   b  of the cylinder  140 . Then, the cylinder  140  is moved in the direction away from the third container  63 . Thus, the inclination of the third valve  63   a  with respect to the third container  63  returns to the vertical state, stopping ejection of the third fluid from the third ejection nozzle  51 . 
   In still another embodiment as shown in  FIG. 36 , a fourth ejection nozzle  160  is provided to the third container  63  in place of the third ejection nozzle  150 . The fourth ejection nozzle  160  has a shape roughly like a hammer, and is composed of a support  162  and a nozzle portion  163  in place of the arm  152  and nozzle portion  153  of the third ejection nozzle  150 . 
   Referring to  FIGS. 37A to 37C , the support  162  is formed by making a cylindrical portion  162   a  with a through hole  162   b  and a head portion  162   f  intersect each other. A convex  162   e  extending axially is formed on the outer periphery of the cylindrical portion  162   a . The convex  162   e  engages in a groove  151   d , and one end  162   h  of the cylindrical portion  162   a  fits in the fit portion  151   c . A wedge-shaped inner surface  162   j  is formed on the head portion  162   f , and has a bottom formed with an opening  162   k . A thorough hole  162   b  is connected to the inner surface  162   j.    
   Referring to  FIGS. 38A to 38C , a nozzle portion  163  of a wedge shape includes a wedge portion  163   a  and a plate portion  163   b . A groove  163   c  is formed in one surface of the wedge portion  163   a , which is linked with an end face of the wedge portion  163   a . A concave  163   d  is formed in the other surface of the wedge portion  163   a.    
   Referring to  FIG. 39 , the fourth ejection nozzle  160  is formed by press fitting the wedge portion  163   a  of the nozzle portion  163  into the inner surface  162   j  of the head portion  162   f . With this, the groove  163   c  and the inner surface  162   j  of the head portion  162   f  cooperate to define part of a fourth circulation path that communicates with the through hole  152   g . Specifically, fluid flowing through the through hole  162   b  strikes the bottom of the groove  163   c  and turns to the opening  162   k  for ejection therefrom. 
   Referring to  FIG. 40 , the adaptor  121  uses a fourth container  64  provided with a press-down-type valve in place of the third container  63  provided with a tilt-type valve. A cylinder  140 ′ includes a convex  149  in the center of the collar  147 . When the cylinder  140 ′ is moved axially (direction of an arrow), the convex  149  pushes the third ejection nozzle  150 , so that the content of the fourth container  64  is ejected from the spout  153   d  of the third ejection nozzle  150 . Therefore, the cleaning implement  10  using the fourth container  64  provided with a press-down-type valve can carry out ejection in a given range even if pulling conditions of the lever  71  change during cleaning, since an angle of the third ejection nozzle does not change.
