The present invention relates to a cleaning tool including a cleaning head that is used by attaching a cleaning sheet.
By supplying a liquid agent such as liquid detergent or wax to the cleaning cushion part of the cleaning head and moistening the cleaning sheet attached to the cleaning cushion part or the cleaning cushion part, the floor surface or the like is cleaned. Various cleaning tools that can efficiently perform surface cleaning and finishing have been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).
Here, the cleaning tool of patent document 1 provides the liquid agent to the pad for application (cleaning cushion part) via a discharge valve by providing the bottle which sealed and accommodated the liquid agent in the cleaning head, and applying a pressure to a bottle. The liquid agent is applied to a surface to be cleaned such as a floor surface. Moreover, the cleaning tool of patent document 2 supplies a liquid agent to the cleaning sheet attached to the cleaning head from the cleaning liquid storage container by providing a cleaning liquid storage container in the cleaning head and applying pressure to the cleaning liquid storage container. The cleaning sheet is made wet. Further, in the cleaning tool of Patent Document 3, a cartridge containing a cleaning liquid is attached to a box (cleaning head), and the pressure of the pump provided on the handle is used to remove the cleaning head via a nozzle disposed on the cartridge. The cleaning liquid is supplied to the surface.
JP 2000-70205 A JP-T 2005-528941 JP 2000-201877 A
However, in the above-mentioned conventional cleaning tools that clean and finish the surface to be cleaned such as the floor surface with the cleaning cushion part and the cleaning sheet moist, all of them are bottles and cleaning liquid storage containers installed on the cleaning head. Alternatively, pressure is directly applied to the cartridge by human power, and the liquid agent is discharged from a plurality of small-hole nozzle portions. For this reason, for example, immediately after pressure is applied, a large amount of liquid agent is applied to the surface to be cleaned through the small hole-shaped nozzle portion, but thereafter the liquid agent is gradually applied until the pressure is applied again. As a result, the amount of application tends to vary, making it difficult to apply the liquid agent to the surface to be cleaned in an even and uniform manner. Further, since the liquid agent is discharged through the small hole-shaped nozzle portion, the liquid agent is likely to be unevenly distributed on the cleaning sheet in the vicinity of the nozzle portion, and as a result, the liquid agent is unevenly present on the surface to be cleaned and is left as it is. As a result, liquid coating unevenness and the like may occur, resulting in poor cleaning finish.
Therefore, when the cleaning operator recognizes such uneven distribution, it has responded by repeatedly moving the head to the left and right in a wide range and extending the liquid agent thinly and widely, causing the efficiency of the cleaning operation to decrease. . Further, if the cleaning operator is unaware of the uneven distribution of the liquid agent discharged on such a cleaning sheet and ends the cleaning operation, the cleaning finish may be deteriorated as a result.
On the other hand, the inventors of the present application provide a liquid sustained release portion having a sustained release function for gradually releasing a pressurized fluid while passing through a large number of fine channels while providing a tank portion for excluding the liquid agent above the cleaning head. Using the hydrostatic pressure that is provided on the cleaning head and is constantly loaded by the liquid head difference of the liquid contained in the tank, even if no manual pressure is applied, the liquid is stable and evenly distributed from the liquid sustained release part. We are developing a cleaning tool that can be applied to the surface to be cleaned while being slowly released.
In such a cleaning tool, for example, when the supply of the liquid agent from the tank unit to the liquid sustained release unit is stopped, the cleaning operation is once completed after the cleaning operation is temporarily completed, the cleaning operation is performed for a long time, etc. For some reason, it may be difficult to apply the liquid agent substantially evenly. Therefore, it is desired to develop a new technique for allowing the liquid agent to be easily restored to a state where the liquid agent is gradually and uniformly released over the entire liquid sustained-release portion. Further, depending on the cleaning work, there may be a case where it is desired to temporarily release a larger amount of liquid from the liquid sustained release portion.
An object of the present invention is to provide a cleaning tool that facilitates an operation of applying a liquid agent to a surface to be cleaned substantially evenly and contributes to an improvement in the efficiency of cleaning work and an improvement in the finish of cleaning.
In addition, the present invention can be easily restored to a state in which the liquid agent is gradually released evenly in the entire liquid sustained-release part even if non-uniformity (non-uniformity, bias) occurs in the liquid agent release of the liquid sustained-release part. It is an object of the present invention to provide a cleaning tool capable of temporarily releasing a large amount of liquid agent from a liquid sustained release portion as necessary.
The present invention is a cleaning tool in which a cleaning sheet is attached to a cleaning head, the cleaning head including a liquid reservoir portion and a plurality of fine flow paths by applying pressure to the liquid agent supplied to the liquid reservoir portion. A liquid sustained release mechanism comprising a liquid sustained release portion that gradually discharges to the cleaning surface of the cleaning head while passing through the liquid, and the liquid sustained release portion faces at least one of the cleaning surfaces of the cleaning head. The above-mentioned problem is solved by providing a cleaning tool that is provided continuously over substantially the entire width of the cleaning head as viewed from the direction.
Here, the pressure includes not only the case where pressure is directly and indirectly applied to the liquid agent by a pressurizing means such as a pump, but also so-called hydrostatic pressure generated by installing the liquid agent above the discharge part.
In addition, the liquid gradual release portion is provided over substantially the entire width of the cleaning head viewed from at least one direction, preferably from a direction facing the main direction in which the cleaning head is moved when performing the cleaning operation. When the cleaning head is viewed, it means that the liquid sustained release portion is continuous over substantially the entire width in the width direction excluding both ends of the cleaning head. Moreover, the liquid slow release part should just be continuous in the width direction, when it sees from the said at least one direction, and may be provided in the state intermittent when it sees from the other direction. Furthermore, it is preferable that the liquid sustained release portion is provided continuously over substantially the entire width in the width direction of the cleaning head, for example, when viewed from a direction perpendicular to at least one direction. . For example, in the case where the bottom surface serving as the cleaning surface of the cleaning head has a substantially rectangular shape, the liquid sustained release portion is continuous over substantially the entire width in the long side direction when viewed from the short side direction. Even when viewed from the long side direction, it is preferable that the liquid sustained release portion is continuous over substantially the entire width in the short side direction.
According to the cleaning tool of the present invention, it is possible to facilitate the operation of applying the liquid agent substantially evenly to the surface to be cleaned, and to contribute to the improvement of the efficiency of the cleaning work and the improvement of the cleaning finish.
The handle connected to the cleaning head is provided with a tank portion that communicates with the liquid reservoir portion via a liquid supply pipe, and the tank portion is provided with a pressurizing unit that applies pressure to the hydrostatic surface of the stored liquid agent. With this, even if non-uniformity (non-uniformity, bias) occurs in the liquid release of the liquid sustained-release part, it can be easily restored to a state in which the liquid drug is gradually released substantially uniformly throughout the liquid sustained-release part. If necessary, a large amount of liquid can be temporarily released from the liquid sustained-release part.

Furthermore, in the present embodiment, the pressurizing means 22 has a hollow interior communicating with the tank portion 13 and has a function of allowing the inflow of air from the outside air and blocking the outflow of air to the outside air. (Not shown) and a hollow elastic body (see FIGS. 2A and 2B), and by compressing and deforming the hollow elastic body 22, pressure is applied to the hydrostatic surface of the liquid agent. Yes.
In the present embodiment, the cleaning head 11 and the handle 12 are connected via a known universal joint 18. As a result, the handle 12 can be changed not only in the front-rear direction along the vertical plane with respect to the cleaning head 11, but also in the front-rear and left-right directions, and in any direction of 360 °. The head angle of the cleaning head 11 can be adjusted.
As shown in FIG. 3, the cleaning head 11 has a substantially rectangular planar elastic surface with a flat bottom surface 17a on the lower surface side of the synthetic resin head body 19 formed to have a substantially rectangular planar shape. A cleaning cushion 17 is attached. A handle 12 is connected to the central portion of the upper surface of the head main body 19 via a universal joint 18 and receives a pressing force from the handle 12 during cleaning, and the bottom surface 17a of the cleaning cushion 17 has a cleaning sheet interposed therebetween. It is in contact with the surface to be cleaned while being moderately pressed.
Further, on the upper surface portion of the head main body 19, known sheet holding portions 20 made of a flexible elastic material having zigzag-shaped slits 20 a are arranged at the peripheral portion of the upper surface portion and provided at four locations.

For example, after winding a cleaning sheet (not shown) around the cleaning head 11 so as to cover the cleaning cushion part 17 on the lower surface side, the edge of the cleaning sheet is pushed into the sheet holding part 20 through the slit 20a. Thus, the cleaning sheet is easily attached to the cleaning head 11 so as to be detachable and replaceable.
Further, a pipe insertion sleeve 26 is provided on the upper surface portion of the head main body 19 so as to protrude upward at a position adjacent to the universal joint 18 and corresponding to a central portion of a mounting recessed fitting portion 25 described later. A lower end portion of the liquid supply pipe 21 is inserted into the pipe insertion sleeve 26 and attached to a pipe attachment portion 24 of the liquid sustained release mechanism 16 described later.
Further, as shown in FIG. 4, a liquid slow release mechanism 16 including a liquid pool part 14 and a liquid slow release part 15 is provided inside the head body 19. In the present embodiment, the liquid sustained release mechanism 16 is a cartridge-type member that can be attached and detached. As shown in FIGS. 5 (a) and 5 (b), the liquid slow release mechanism 16 is closed at both ends by a system lid 14a and has locking ribs 14b bent inward at both side edges of the lower surface opening. A synthetic resin liquid reservoir 14 which is a tubular tank portion having a substantially inverted U-shaped cross-sectional shape, and a substantially T-shaped cross-sectional shape, such as a resin sintered body, felt, open-cell sponge, It is comprised by the liquid sustained release part 15 which consists of porous materials, such as a pulp, a nonwoven fabric, and rubber | gum. As apparent from FIG. 5A, the liquid reservoir portion 14 has a length and width substantially corresponding to the liquid sustained release portion 15, and extends over substantially the entire width of the cleaning head 11, similar to the liquid sustained release portion 15.

It is efficiently supplied to the entire liquid sustained release portion 15.
Here, the liquid sustained release portion 15 of the liquid sustained release mechanism 16 has a large number of, for example, porous materials when passing the liquid agent supplied from the tank portion 13 to the liquid reservoir portion 14 by the action of hydrostatic pressure from above. The surface tension by the fine flow path has a function of suppressing the passage speed of the liquid agent and ejecting the liquid agent substantially uniformly so as to exude the liquid agent, that is, a function of gradually releasing the liquid agent. In order to effectively exhibit such a function, the amount of the solution released is preferably 0.01 to 0.5 g / sec, more preferably 0.02 to 0.4 g / sec, and 0.04 to 0.3 g. / sec is particularly preferred. The amount of the liquid agent released can be adjusted by appropriately selecting the properties of the liquid agent such as the interfacial tension and viscosity with the porous material, and the state of the porous material such as the pore size and the porosity. By appropriately selecting the liquid permeability of the liquid material in the porous material, or by appropriately designing the hydrostatic pressure and the liquid agent discharge area of the liquid agent, it is possible to appropriately adjust the discharge amount required for wet cleaning. When the porous material is selected using air permeability as an index of air permeability, it is preferable to use a material having a thickness of 0.5 to 200 μm / (Pa · sec), More preferably, those of 1.0 to 50 are particularly preferred.
The liquid sustained-release part 15 has a substantially T-shaped cross-sectional top surface part 15a supported by the locking rib 14b and disposed inside the liquid storage part 14, and a substantially T-shaped cross-sectional leg part 15b. It is attached to the liquid reservoir portion 14 in a state of projecting downward from a slit-like opening between the locking ribs 14b on both sides. As a result, the cartridge-type liquid sustained release mechanism 16 is formed so that the shape seen from the side has a strip shape.
In the present embodiment, the liquid reservoir portion 14 has a capacity of, for example, about 0.5 to 2 cc, and protrudes upward from the central portion thereof, and the pipe mounting portion 24 is provided. The lower end portion of the liquid supply pipe 21 is detachably attached to the pipe attachment portion 24 in a liquid-tight state.

By storing them, a so-called buffer function is exhibited so that a uniform hydrostatic pressure is applied from above over the entire top surface portion 15a of the liquid sustained release portion 15.
In addition, a plurality of support ribs 14 c are provided inside the liquid reservoir portion 14 so as to protrude downward from the inside of the top end portion of the liquid reservoir portion 14 in the axial direction of the liquid reservoir portion 14. The tip of the support rib 14c is brought into contact with the top surface of the top surface portion 15a of the liquid gradual release portion 15, and the liquid gradual release portion 15 is subjected to reaction force from the surface to be cleaned by the pressing force applied to the cleaning head 11 during cleaning. Functions as a liquid sustained release portion holding means for preventing the liquid from moving upward and being excessively pushed into the liquid reservoir 14. Instead of the support rib 14c, a step extending in the axial direction of the liquid reservoir portion 14 may be provided to serve as the liquid sustained release portion holding means.
And in this embodiment, the liquid sustained release mechanism 16 which consists of the liquid reservoir part 14 and the liquid sustained release part 15 is attached to the inside of the head main body 19 so that attachment or detachment is possible, as shown in FIG. In other words, in the present embodiment, the length of the cleaning head 11 is set inside the head body 19 between, for example, the universal joint 18 and a pair of sheet holding portions 20 along a long side of the head body 19. A mounting recess 25 is provided that is disposed substantially parallel to the direction Y and opens toward the lower surface of the head body 19 (see FIG. 3). For example, in a state where the lower end portion of the liquid supply pipe 21 is attached to the pipe attachment portion 24, the cartridge type liquid sustained release mechanism 16 is fitted from the lower side of the mounting concave fitting portion 25 while the liquid reservoir portion 14 is disposed upward. For example, in a state where the system lids 14 a at both ends of the liquid reservoir 14 are respectively fitted in the system recesses 23 provided at both ends of the mounting recess 25, biasing means such as a spring is provided. The liquid slow release mechanism 16 can be easily attached to the inside of the head main body 19 by engaging the system attachment protrusion 27 that can be advanced and retracted through one end of the system attachment lid 14a.
As shown in FIGS. 6A and 6B, a cleaning cushion 17 is attached to cover the lower surface of the head main body 19. In the cleaning cushion 17, a slit groove 28 having the same width as the liquid sustained release mechanism 16 is formed at a position corresponding to the mounting recessed portion 25 of the head main body 19. The liquid slow release mechanism 16 is inserted into the slit groove 28 from the bottom surface 17a side by the cleaning cushion 17 of the cleaning head 11, for example. As a result, the lower end surface 15c of the leg portion 15b of the liquid sustained release mechanism 15 of the liquid sustained release mechanism 16 is flush with or substantially flush with the bottom surface 17a so as to face the bottom surface 17a serving as the cleaning surface of the cleaning head 11. It arrange | positions so that it may be provided in strip shape. Further, the lower end surface 15c of the leg portion 15b of the liquid sustained release portion 15 is continuously arranged in a straight line so as to be parallel to the long side of the cleaning head 11 having a substantially rectangular planar shape. Furthermore, the lower end surface 15c of the leg portion 15b of the liquid gradual release portion 15 is brought into contact with the surface to be cleaned through the cleaning sheet together with the bottom surface 17a of the cleaning cushion portion 17 by the pressing force to the cleaning head 11 at the time of cleaning. Become.
Here, in this embodiment, the width of the lower end surface 15c of the liquid sustained release portion 15 facing the cleaning surface 17a of the cleaning head 11 is 1/10 of the length of the short side of the cleaning head 11 having a substantially rectangular planar shape. However, this width can be appropriately determined according to the distribution amount of the liquid agent, the design moving speed of the cleaning head 11 during the cleaning operation, and the like. The length of the liquid gradual release portion 15 is preferably as close as possible to the length of the long side of the cleaning head 11 because it is less necessary to move the head to the left and right during the application work. Etc., which is about 30 mm shorter.
Further, the lower end surface 15c of the liquid gradual release portion 15 has a slight protruding height, for example, a protruding height s from the cleaning surface 17a of the cushion portion 17 in a no-load state is larger than 0 mm and smaller than 2 mm, It protrudes downward from the bottom surface 17 a of the cushion portion 17. Since the lower end 15c of the liquid sustained release portion 15 protrudes downward from the cleaning surface 17a of the cushion portion 17 with a slight protruding height, the liquid agent that is gradually released from the liquid sustained release portion 15 by the pressing force to the cleaning head 11 It becomes possible to adjust the amount. On the other hand, even if a pressing force is applied to the cleaning head 11, the cleaning cushion portion 17 exists around the lower end 15 c of the liquid gradual release portion 15. It is possible to release the liquid formulation.
Furthermore, as shown in FIG. 7, the lower end surface 15c of the liquid sustained release portion 15 does not protrude from the cleaning surface 17a of the cushion portion 17 in a no-load state, for example, with a depth s ′ not exceeding 2 mm. It can also be provided in a state of being recessed from the 17 cleaning surface 17a. Even when the lower end surface 15c of the liquid sustained-release part 15 does not protrude from the cleaning surface 17a of the cushion part 17, the liquid agent is released from the liquid sustained-release part 15 before being dropped by the surface tension or the like before dropping. It moves to the cleaning sheet which covers, and spreads to the said cleaning sheet. Moreover, when the cushion part 17 press-deforms with the pressing force to the cleaning head 11, the lower end surface 15c of the liquid sustained release part 15 will contact a to-be-cleaned surface via a cleaning sheet.
In the case where the cleaning head 11 is configured by a member having elasticity and the liquid sustained release portion 15 is configured by a member that has substantially no elasticity such as sintered metal or is less elastically deformed than the cleaning head 11, the liquid sustained release is performed. It is preferable to provide the lower end surface 15c of the part 15 in a state of being recessed from the cleaning surface 17a.
As shown in FIG. 1, the handle 12 connected to the cleaning head 11 via the universal joint 18 is made of, for example, a synthetic resin pipe member, and is used for cleaning work while standing with the cleaning tool 10. It has a suitable length, for example, about 50 to 120 cm. A cylindrical tank portion 13 is provided on the handle 12 so as to constitute a part of the grip portion. Furthermore, a liquid supply pipe 21 that communicates between the tank portion 13 and the liquid reservoir portion 14 of the above-described liquid sustained release mechanism 16 provided in the cleaning head 11 is disposed in the hollow interior of the handle 12. It is also possible to use the handle 12 itself as a liquid supply pipe by providing a seal.
The tank portion 13 is preferably formed in a cylindrical shape using a transparent synthetic resin, and is attached to the upper portion of the handle 12 as a unit with the handle 12. The tank unit 13 has an internal capacity of about 20 to 100 cc, for example, and as shown in FIGS. By opening and closing the lid member 29 that includes the hollow elastic body 22 as a unit, a liquid agent such as a liquid cleaning agent or wax can be appropriately replenished.

It is possible to easily switch between the closed state (see FIG. 2A) and the state in which the base portion 35 is opened and the upper surface opening of the fixed sleeve portion 30 is opened (see FIG. 2B). ing. The lid body 31 is provided with a locking claw 34. By locking and fixing the locking claw 34 to the locking projection 38 of the fixed sleeve portion 30 while elastically deforming, the upper end opening of the tank portion 13 (the upper surface opening of the fixed sleeve portion 30) is airtight by the lid main body portion 31. The closed state can be firmly held. Furthermore, the upper end opening of the tank portion 13 can be easily opened by releasing the engagement state with the engagement protrusion 38 by pressing the release operation portion 34a of the engagement claw 34.
In the present embodiment, the lid main body 31 is a part constituting the hollow elastic body 22 as a pressurizing means. The lid main body 31 includes a disk-shaped base part 35 and a spherical part 36 that is swelled in a spherical shape on the upper surface side of the base part 35 and formed integrally. The base portion 35 is rotatably connected to the fixed sleeve portion 30 via the hinge portion 32, and protrudes downward from the lower surface side to be provided with the fitting convex portion 33 described above. The base portion 35 has a function of allowing air to flow from outside air into the hollow elastic body 22 and blocking air from flowing out of the hollow elastic body 22 into the outside air. (Not shown) is provided. In addition, a ventilation channel 37 that passes through the center of the base portion 35 and communicates the hollow interior of the hollow elastic body 22 and the tank unit 13 is provided, and a known check valve ( (Not shown) is provided to allow air to flow from the hollow elastic body 22 to the tank portion 13 and to block the return of air and liquid from the tank portion 13 to the hollow elastic body 22.

A function of applying pressure to the hydrostatic surface of the liquid agent accommodated in the tank unit 13 is provided. Further, when the pressing of the spherical portion 36 is released, the spherical portion 36 returns to its original shape while taking air into the inside through the check valve due to its elasticity.
The liquid supply pipe 21 that communicates the tank unit 13 and the liquid slow release mechanism 16 of the cleaning head 11 is made of, for example, a flexible synthetic resin tube material. The liquid supply pipe 21 is connected to the tank portion 13 at the upper end of the liquid supply pipe 21 and is disposed in the handle 12 so as to extend downward, and then is opened at the lower end portion of the handle 12. It is led out to the outside of the handle 12 through the hole 39 (see FIG. 1).

The jig is used to mount the liquid sustained release mechanism 16 on the pipe mounting portion 24 in a liquid-tight state.
Further, the liquid supply pipe 21 is provided with an open / close valve (not shown) for supplying or stopping the liquid agent from the tank portion 13 to the liquid reservoir portion 14 of the liquid sustained release mechanism 16 inside the handle 12. Is provided. The open / close valve can be easily opened and closed by an operation from an open / close lever 40 (see FIG. 1) provided outside the handle 12, for example. By opening / closing the open / close valve, for example, when the cleaning tool 10 is used, the tank 13 and the liquid reservoir 14 are connected to each other, and a liquid agent can be supplied while applying a hydrostatic pressure to the liquid reservoir 14. When the device 10 is not in use, the communication between the tank portion 13 and the liquid reservoir portion 14 is cut off so that the hydrostatic pressure is not applied to the liquid reservoir portion 14 and the supply of the liquid agent is easily stopped. It can be switched.
In the cleaning tool 10 of the present embodiment having the above-described configuration, when performing a cleaning operation or a finishing operation, a cleaning sheet is attached to the cleaning head 11 so as to cover the bottom surface 17a of the cleaning cushion portion 17, and the opening / closing valve is opened. Then, a hydrostatic pressure is applied to the liquid reservoir 14 of the liquid sustained release mechanism 16, and the liquid agent can be constantly supplied from the tank 13 to the liquid reservoir 14. As a result, the liquid agent is gradually and substantially gradually supplied from the entire liquid sustained-release portion 15 of the liquid sustained-release mechanism 16 to the cleaning sheet. It is possible to efficiently perform the cleaning operation and the finishing operation in a stable state while applying the liquid agent substantially evenly to the surface to be cleaned such as the surface.
On the other hand, in the cleaning tool 10 of this embodiment, for example, when the supply of the liquid agent from the tank unit 13 to the liquid sustained release mechanism 16 is stopped and the cleaning operation is once completed, the cleaning operation is performed again, or the cleaning operation is prolonged. For example, part or the whole of the liquid sustained-release part 15 made of a porous material may be clogged due to some factor such as drying of the liquid agent or adhesion of dust, etc. There is a possibility that retention of the atmosphere may occur and it may be difficult to apply the liquid agent substantially uniformly. Further, depending on the cleaning operation, there may be a case where it is desired to temporarily release more liquid agent from the liquid sustained release mechanism 16. On the other hand, in the cleaning tool 10 of this embodiment, since the hollow elastic body 22 is provided as a pressurizing means for applying pressure to the hydrostatic surface of the liquid agent accommodated in the tank portion 13, the liquid sustained release portion Even if clogging occurs in 15 or air stays in the liquid reservoir 14, the liquid sustained release mechanism 16 can be easily restored to a state in which the liquid agent is gradually released evenly. In addition, a large amount of liquid agent can be temporarily released from the liquid sustained release portion as necessary.
That is, according to this embodiment, for example, clogging occurs in the liquid sustained release portion 15 made of, for example, a porous material, or air stays in the liquid reservoir portion 14, and the liquid agent cannot be applied substantially uniformly. Then, if the spherical body portion 36 of the hollow elastic body 22 is pressed and compressed and deformed, a considerable pressure is applied to the hydrostatic surface of the liquid agent accommodated in the tank portion 13, so that the pressure applied to the hydrostatic surface is reduced. Is transmitted to the liquid reservoir portion 14 to increase the liquid pressure of the liquid agent passing through the liquid sustained release portion 15 made of a porous material. This increased fluid pressure makes it possible to easily eliminate clogging of the liquid slow release portion 15 and retention of air in the liquid reservoir portion 14. In addition, when a large amount of liquid agent is temporarily released, if the spherical portion 36 of the hollow elastic body 22 is pressed and compressed and deformed, the liquid pressure of the liquid agent passing through the liquid sustained release portion 15 made of a porous material is increased. Since it increases, it becomes possible to discharge more liquid agent from the liquid slow release part 15 by this increased liquid pressure.
Moreover, according to the cleaning tool 10 of this embodiment, the liquid slow release part 15 faces the bottom surface 17a which becomes the cleaning surface of the cleaning head 11, and the short side (short side) of the cleaning head 11 provided with a substantially rectangular planar shape. It is provided continuously over the entire width of the cleaning head 11 as viewed from the direction X (see FIG. 3), that is, from the direction of the arrow X ′ in the figure. Therefore, if the cleaning head 11 is moved in the short direction X of the cleaning head 11 which is the main direction in which the cleaning head 11 is moved when performing the cleaning operation, the top surface portion 15a of the liquid sustained release portion 15 via the liquid reservoir portion 14. In a state where a substantially equal hydrostatic pressure is applied from above, the liquid agent is not unevenly distributed over the substantially entire width in the longitudinal direction Y of the cleaning head 11 from the lower end surface 15c of the liquid sustained release portion 15. It will be evenly supplied to the cleaning sheet, thereby facilitating the operation of applying the liquid agent almost evenly to the surface to be cleaned, and effectively contributing to the improvement of the efficiency of cleaning work and the finishing of cleaning. Is possible.
Since the liquid sustained release portion 15 is detachable from the cleaning head 11, replacement or washing when the liquid sustained release portion 15 becomes dirty can be easily performed, and the liquid sustained release portion 15 is provided continuously. Can be attached and detached more easily.
The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, a liquid sustained release mechanism composed of a liquid reservoir part and a liquid sustained release part does not necessarily have to be a cartridge-type member that can be attached to and detached from the cleaning head, and is integrated into the cleaning head. Also good. Only the liquid slow release part may be configured to be detachable and replaceable. The pressurizing means for applying pressure to the hydrostatic surface of the liquid agent accommodated in the tank part does not necessarily need to be a compressible and deformable hollow elastic body, and is provided slidable along the inner peripheral surface of the tank part, for example. A piston member or the like may be used. Furthermore, the tank portion does not necessarily have to be attached as a part of the handle portion of the handle, and can be provided as a separate member on the side portion of the handle, for example.
Further, the liquid agent may be one that is directly and indirectly applied to the liquid agent by a pressurizing means such as a pump, in addition to one that is sent to the liquid sustained release portion by hydrostatic pressure. The cleaning tool may perform a cleaning operation by directly gripping the cleaning head without connecting a handle to the cleaning head. The bottom surface of the cleaning head is not necessarily provided with a substantially rectangular shape, and may have various other shapes suitable for cleaning work such as an oval shape.
Furthermore, as a form which provides the liquid slow release part provided so that it may face the bottom face of a cleaning head over substantially the full width of the width of the cleaning head seen from at least one direction, it shows, for example in FIG. Various examples can be exemplified, and among these, (a), (c), (d), and (e) can be cited as continuous ones.
