Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0009061, filed on Jan. 22, 2021, the disclosure of which is incorporated herein by reference in its entirety. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a shower head with a one-touch detachable structure, and more particularly, to a shower head which is installed in a bathroom or on a sink and has a handle body which is easily detachable from an end portion of a hose in one-touch by women or the old and the infirm. 
     Background Art 
     In general, a shower head which is installed in a bathroom or on a sink is a device which is connected with a valve of a water pipe to spray water flowing through a water supply. A hose connected with a valve is combined with an end of the shower head. 
     The shower head includes: a handle which allows a user to grasp with the hand and of which the end is combined with a hose; and a head part formed at the upper end of the handle to spray raw water. In this instance, the handle has a hollow part formed therein to guide the raw water flowing through the hose to the head part. 
     The shower head has a structure to spray mainly tap water as raw water. Recently, functional shower heads having multiple functions are coming out. Korean Patent Publication No. 10-2016-0087498 (literature cited) discloses a functional shower head. The functional shower head includes: 
     a head part having a hollow part, in which raw water is temporarily stored, and an opening part with an open front surface; a water pressure increase plate having multiple discharge holes, which discharge the raw water flowing into the hollow part by being connected to the open front surface of the head part and are formed at the center or an edge, and a first guide part or a third guide part formed on the rear surface to guide the raw water flowing into the hollow part to the discharge hole; a water spray plate having multiple fine water discharge holes spraying the raw water discharged through the discharge hole of the water pressure increase plate and mounted on the front of the water pressure increase plate to maintain intervals by a spacer unit; a connection part accommodating the water spray plate, the spacer, and the water pressure increase plate therein and assembled to the head part to be detached; and a handle connected to the head part and having a flow path guiding the raw water flowing through a hose to the head unit. 
     Here, the handle of the shower head disclosed in the literature cited has a male thread formed on the outer peripheral surface of the lower end thereof to connect the hose. So, if the hose is not firmly coupled with the male thread, water may leak through the screw-coupled part. Accordingly, the conventional shower head has a disadvantage in that it is difficult for women or the old and the infirm who have weak wrist power and grasping power to attach or detach the shower head to or from the hose. 
     Moreover, the conventional shower head has another disadvantage in that a user has to rotate the handle several times when attaching or detaching the shower head to or from the hose since the handle of the shower head and the hose are screw-coupled. 
     Furthermore, the upper end of the handle of the shower head is screw-coupled to an inlet formed at the lower portion of the head body, and a cylindrical filter member is mounted in a water passage of the handle in order to filter foreign matters of the raw water. Therefore, if the filter member is contaminated, the user has to separate the handle screw-coupled with the head part, and wash the contaminated filter member or replace it with a new one. However, because the conventional shower head has the structure that the head part and the handle are screw-coupled with each other, if the head part is not firmly coupled with the handle, water may leak through the screw-coupled part. Accordingly, there is difficulty in that women or the old and the infirm who have weak wrist power and grasping power attach or detach the head part to or from the handle to wash or replace the filter member. 
     Moreover, the conventional shower head has another disadvantage in that a user has to rotate the handle several times when attaching or detaching the shower head to or from the hose since the handle of the shower head and the hose are screw-coupled. 
     Additionally, there is inconvenience in that the user has to rotate the head part or the handle several times when attaching or detaching the head part to or from the handle since the head part and the handle are screw-coupled with each other.

       FIGS. 1 to 9  illustrates a shower head with a one-touch detachable structure according to a first preferred embodiment of the present invention. 
     The shower head  1  according to the first preferred embodiment of the present invention is installed in a bathroom or on a sink to be usable. The shower head  1  includes: a handle body  10 , which has a body  11 , a flow path  12  formed in the body  11  so that tap water can flow, and a lower end to which a hose  20  connected with a faucet  2  is connected so that a user can grasp it with the hand; and a head assembly  30  which is detachably combined with the upper end of the handle body  10  and has a water spray board  31  having fine water discharge holes  31   a  for spraying tap water introduced through the flow path  12 . 
     Hereinafter, the configuration of the shower head according to the present invention will be described in detail. 
     The handle body  10  is made of a synthetic resin material or a metallic material. A user grasps the handle body with the hand in order to spray tap water using the shower head  1 . The body  11  has a flow path  12  formed therein so that tap water moves to an outlet  14  of the upper end through the flow path  12  when tap water is introduced from an inflow connection part  13  of the lower end connected with the hose  20 . 
     In this instance, the handle body  10  is formed in a cylindrical shape so that the user can grasp it easily, but may be formed in one among various shapes, such as a polygonal tube, in consideration of designs. 
     A cylindrical filter member  40  for filtering foreign matters of raw water introduced from the inflow connection part  13  of the lower end is mounted in the flow path  12  of the handle body  10  so as to prevent the fine water discharge holes  31   a  of the spray board  31  from being blocked by the foreign matters of the raw water. 
     The filter member  40  is manufactured with nonwoven fabric of 0.3 mm or less which is rolled cylindrically manyfold or is made up of well-known sediments. The filter member  40  includes: a cylindrical filter body  41  which has a passage  41   a  formed in the middle; a lower cap  42  which is coupled to the lower end of the filter body  41  to finish the lower end of the passage  41   a  and has a guide hole  42   a  formed in the bottom surface in order to guide the raw water introduced through the filter foreign matters of raw water introduced from the inflow connection part  13  of the handle body  10  to the outside of the filter body  41 ; and an upper cap  43  which is coupled to the upper end of the filter body  41  and has a discharge hole  43   a  formed at the center so that the purified raw water introduced into the passage  41   a  is discharged. 
     Of course, an O-ring  44  for preventing water leak is mounted on the outer peripheral surface of the upper cap  43  to get in contact with the inner peripheral surface of the outlet  14  of the handle body  10 . 
     Moreover, the head assembly  30  includes: a head housing  32  having a space part to which tap water discharged through the handle body  10  is introduced, and a coupling part  421  disposed on the lower portion of the head housing to be coupled with the upper end of the handle body  10  and having inflow holes  421  through which tap water is introduced; the spray board  31  attached to the front of the head housing  32  and having the plurality of fine water discharge holes  31   a  for spraying tap water; and a front cover  33  coupled to the front end of the head housing  32  to fix the spray board  31  onto the head housing  32 . 
     In the meantime, the inflow connection part  13  disposed at the lower end of the handle body  10  has an outer diameter which gets gradually narrower toward the lower end, so can be held on a holding recess  3   a  of a shower head holder  3  fixed on the wall surface on which the faucet  2  is installed. 
     The inflow connection part  13  can be formed integrally with the handle body  10 , and has a coupling groove  13   a . Preferably, the coupling groove  13   a  is formed on the lower end of the handle body  10  to be stepped. 
     Meanwhile, a first connection means  100  is disposed at an end portion of the hose  20 , and a second connection means  200  is disposed on the inflow connection part  13  disposed at the lower end of the handle body  10  to be detachably connected with the first connection means  100 . 
     In this instance, the first connection means  100  is mounted at the front end of the hose  20  and has a male coupler  110  having an insertion tube  111  protruding from the front end. The second connection means  200  is mounted on the inflow connection part  13  and has a female coupler  210  for locking or unlocking the insertion tube  111 . The male coupler  110  of the hose  20  is coupled with the female coupler  210  of the inflow connection part  13  disposed at the lower end of the handle body  10  in one-touch so that the inner flow path can be connected or disconnected. 
     In this instance, the male coupler  110  is formed in a cylindrical shape, has an end connected to the hose  20  and the other end from which the insertion tube  111  fit into the female coupler  210  extends, and has a retaining groove  112  formed on the outer peripheral surface of the insertion tube  111 . 
     Additionally, the female coupler  210  includes: a first sealing member  211  and a second sealing member  212  each of which one side is fit and seated onto the coupling groove  13   a  of the inflow connection part  13  disposed at the lower end of the handle body  10 ; a holder ring  213  having an elastic piece  213   a  caught to the retaining groove  112  formed on the outer peripheral surface of the insertion tube  111  of the male coupler  110 ; a cap ring  214  which presses the holder ring  213  in the direction of the second sealing member  212  to fix the holder ring  213  to the coupling groove  13   a  of the inflow connection part  13 ; and a push ring  215  which presses the elastic piece  213   a  of the holder ring  213  caught to the retaining groove  112  formed on the outer peripheral surface of the insertion tube  111  of the male coupler  110  to separate the elastic piece  213   a  from the retaining groove  112 . 
     In this instance, the cap ring  214  has a protruding jaw  214   a  formed on the outer peripheral surface thereof. When the cap ring  214  is fit to the coupling groove  13   a  of the inflow connection part  13  after the first and second sealing members  211  and  212  and the holder ring  213  are inserted into the coupling groove  13   a  of the inflow connection part  13 , the protruding jaw  214   a  is coupled to the retaining groove formed on the inner peripheral surface of the coupling groove  13   a  of the inflow connection part  13  to be fixed firmly, so that the first and second sealing members  211  and  212  and the holder ring  213  are firmly fixed to the coupling groove  13   a  of the inflow connection part  13  without separation. 
     In addition, the second sealing member  212  has a locking jaw  212   a  formed on the outer face thereof, and the cap ring  214  has a locking groove  214   b  formed on the upper portion of the inner wall thereof to support the locking jaw  212   a  of the second sealing member  212 . Therefore, when the holder ring  213  is fit to the inner upper portion of the cap ring  214  to press the second sealing member  212  downwards, the locking jaw  212   a  of the second sealing member  212  is clicked and fixed to the locking groove  214   b  not to be separated. Therefore, the cap ring  214  to which the second sealing member  212  and the holder ring  213  are fixed can be assembled to the inflow connection part  13  easily. 
     Moreover, a fitting protrusion part  212   b  is formed at the upper end of the second sealing member  212 , and a fitting groove  211   a  is formed at the lower portion of the first sealing member  211  so that the fitting protrusion part  212   b  of the second sealing member  212  is inserted into the fitting groove  211   a . Therefore, when the first sealing member  211  is inserted into the second sealing member  212  and the second sealing member  212  is fixed to the cap ring  214  to which the holder ring  213  is fixed, an assembly is formed. Therefore, the assembly can be assembled to the inflow connection part  13  more conveniently. In this instance, the first sealing member  211  is made of a silicon or rubber material, and the second sealing member  212  is made of a synthetic resin material. However, the first and second sealing member  211  and  212  are not limited to the above, but may be made of one among various materials. 
     According to the structures of the male coupler  110  and the female coupler  210 , the shower head  1  can be coupled with or separated from an end portion of the hose in one-touch. In detail, in order to couple the end portion of the hose  20  to the handle body  10  of the shower head  1 , when an insertion tube  111  of the male coupler  110  coupled to the hose  20  passes through the push ring  215  and the cap ring  214  and is pressed more, the elastic piece  213   a  of the holder ring  213  is folded and is inserted into the retaining groove  112  and is restored, so that the insertion tube  111  of the male coupler  110  is not separated from the female coupler  210 . After that, in order to separate the handle body  10  of the shower head  1  from the end portion of the hose  20 , the user has to press the push ring  215 . Then, an inclined pressing part  215   a  of an end portion of the push ring  215  presses the elastic piece  213   a  of the holder ring  213 . After that, the elastic piece  213   a  is bent outwards and is separated from the retaining groove  112  of the male coupler  110 . In this instance, the insertion tube  111  of the male coupler  110  coupled to the hose  20  is separated from the female coupler  210  of the handle body  10 . 
     In the drawings, it is illustrated that the first connection means  100  is disposed at the end portion of the hose  20  and the second connection means  200  is disposed on the shower head  1 , but it is also possible that the second connection means  200  is disposed at the end portion of the hose  20  and the first connection means  100  is disposed at the shower head  1 , and such a simple change of location belongs to the scope of the present invention. 
     In addition, a third connection means  300  is disposed at the upper end of the handle body  10 , and a fourth connection means  400  is disposed at the lower end of the head assembly  30 , so that the third connection means  300  and the fourth connection means  400  are simply attached and detached in one-touch. 
     In this instance, the third connection means  300  is disposed at the upper end of the handle body  10 , and includes: a fixing part  310  extending to the upper end of the handle body  10  and having a third path  311  vertically formed at the center thereof and a plurality of ball seating parts  312  formed on the flank; fixing balls  320  rotatably disposed on the plurality of ball seating parts  312 ; and a push member  330  coupled to the outer peripheral surface of the fixing part  310  to support the fixing balls  320  and being vertically movable along the fixing part  310  to make the fixing balls  320  appear and disappear in the direction of the third path  311 . 
     In this instance, a support jaw  313  is formed on the outer peripheral surface of the fixing part  310 , a spring seating groove  331  is formed on the inner surface of the push member  330 , and a return spring  340  is mounted on the spring seating groove  331  to press the push member  330  upwards. A knurling part  332  which can prevent slip is disposed on the outer face of the push member  300  to protrude when the user pulls the knurling part  332  downwards. 
     Moreover, the fourth connection means  400  is disposed at the lower end of the coupling part  421  of the head assembly  30 , and includes a connection member  410 , which has a connection part  411  protruding downwards to be inserted into the third path  311  of the fixing part  310  and having a fourth path  411   a  formed in the longitudinal direction and a ball support groove  412  formed on the outer peripheral surface of the connection part  411  to support the fixing balls  320  on the same circumference. In this instance, the ball support groove  412  may be formed concavely on the outer peripheral surface of the connection part  411 , but may be formed dividedly by a support protrusion protruding outwards on the same circumference. In this instance, the fixing balls  320  run over the support protrusion and move to the ball support groove  412  if there is no interference of the push member  330 . 
     Furthermore, a ring groove  318  is formed at the upper end of the fixing part  310  and a leakage prevention ring  319  is mounted on the ring groove  318 . When the connection part  411  of the connection member  410  is inserted into the third path  311  of the fixing part  310 , the upper end of the inside of the push member  330  gets in contact with the leakage prevention ring  319  so as to prevent leakage of water. 
     According to the above structure, when the user pulls down the push member  330  with the hand in order to connect the third connection means  300  with the fourth connection means  400 , a physical force applied to the fixing balls  320  by the push member  330  is released, and in this state, the connection part  411  of the connection member  410  can be easily inserted into the third path  311  of the fixing part  310 . 
     After that, when the user releases the push member  330 , the push member  330  returns upwards by restoring force of the return spring  340 , and pushes the fixing balls  320  located on the ball seating parts  312  in the direction of the third path  311  of the fixing part  310 . Therefore, some of the fixing balls  320  is continuously supported on the ball support groove  412  formed on the outer peripheral surface of the connection part  411  of the connection member  410 , so that the third connection means  300  and the fourth connection means  400  are not separated from each other. 
     Of course, in order to separate the third connection means  300  and the fourth connection means  400  from each other, when the user holds and pulls the push member  330 , the push member  330  lowers and the physical force applied to the fixing balls  320  is released. Therefore, the connection part  411  of the connection member  410  can be easily separated from the third path  311  of the fixing part  310 . 
     Furthermore, rotation preventing grooves  310   a  are formed at the upper end of the fixing part  310  of the handle body  10 , and rotation preventing protrusions  421   a  supported in the rotation preventing grooves  310   a  are formed on the coupling part  421  of the head assembly  30 . In this instance, at least one pair of the rotation preventing groove  310   a  and the rotation preventing protrusion  421   a  are disposed. Therefore, when the third connection means  300  and the fourth connection means  400  are coupled with each other, the rotation preventing protrusion  421   a  is supported to the rotation preventing groove  310   a  so as to prevent the head assembly  30  from being rotated from the handle body  10  arbitrarily. 
     Due to the above structure, the handle body  10  and the head assembly  30  can be connected to or separated from each other just by a simple action that the user pulls or pushes the head assembly  30  while pressing the push member  330  disposed at the upper end of the handle body  10 . When the user releases the push member  330  in the state where the handle body  10  and the head assembly  30  are connected with each other, because the push member  330  is returned automatically by the return spring  340  so that the head assembly  30  is not separated from the handle body  10 , the user can use the shower head stably. 
     Additionally, because the user can pull or push the head assembly  30  from or into the handle body  10  just with less power in the state where the push member  330  is pulled downwards, women or the old and the infirm can easily wash or replace the filter member. 
     Moreover, an O-ring  413  which is closely supported on the inner surface of the third path  311  is mounted on the outer peripheral surface of the lower side of the connection part  411  of the fourth connection means  400  in order to prevent water leak at the connected portion when the third and fourth connection means  300  and  400  are connected with each other. 
     In the above, it is described that the third connection means  300  is disposed at the upper end of the handle body  10  and the fourth connection means  400  is disposed at the lower end of the coupling part  421  of the head assembly  30 , but the fourth connection means  400  may be disposed at the upper end of the handle body  10  and the third connection means  300  may be disposed at the lower end of the coupling part  421  of the head assembly  30 . Such a change in design belongs to the scope of the present invention. 
     Meanwhile,  FIGS. 10 and 11  are views for explaining a shower head with a one-touch detachable structure according to a second preferred embodiment of the present invention. 
     In the drawings, the inflow connection part  13  disposed at the lower end of the handle body  10  is screw-coupled. Because the handle body  10  and the inflow connection part  13  can be separated from each other and connected to each other, a male screw thread  15  is extended at the lower end of the handle body  10 , and the inflow connection part  13  is perforated in the longitudinal direction so that tap water can movable therein. Moreover, the inflow connection part  13  has a female screw thread  16  formed on the upper side of the inner peripheral surface, so that the inflow connection part  13  is screw-coupled to the lower end of the handle body  10 . 
       FIG. 12  is a sectional view illustrating a coupled state of a shower head according to a third preferred embodiment of the present invention. Referring to  FIG. 12 , the handle body  10  of the shower head, and the third connection means  300  and the fourth connection means  400  of the head assembly  30  are coupled to each other or separated from each other in one-touch. The male screw thread  15  is disposed at the lower end of the handle body  10 , the inflow connection part  13  is coupled to the end portion of the hose  20 , and the female screw thread  16  is disposed at the inflow connection part  13 , so that the handle body  10  and the hose  20  are connected with each other through screw-coupling. 
     The inflow connection part  13  of the handle body  10  and the hose  20  keeps the firmly connected state, and only the head assembly  30  can be easily separated from the handle body  10  of the shower head. Of course, the cylindrical filter member  40  can be easily separated from the upper end of the handle body  10 . 
     Additionally,  FIG. 13  is a sectional view illustrating a coupled state of a shower head according to a fourth preferred embodiment of the present invention. Referring to  FIG. 13 , the handle body  10  of the shower head, and the first connection means  100  and the second connection means  200  of the hose  20  can be connected to each other and separated from each other in one-touch. A male screw thread  17  is disposed at the lower end of the head assembly  30  and a female screw thread  18  is disposed at the upper end of the handle body  10 , so that the head assembly  30  and the handle body  10  can be screw-coupled with each other. 
     Therefore, the head assembly  30  and the handle body  10  can maintain the firmly connected state and the shower head can be easily separated from the hose  20 . 
     As described above, while the present invention has been particularly shown and described with reference to the example embodiments thereof, it will be understood by those of ordinary skill in the art that the technical scope of the present invention is not limited by the above and all technical ideas within the equivalent scope belong to the technical scope of the present invention.
