[0002] In the prior art, the handle length of a handheld shower is fixed and cannot be extended. In particular, a shower with a bath scrubbing function may not be able to scrub the back or other parts of the body due to the fixed handle length, resulting in a poor user experience. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide a telescopic shower head, which can control the extension and retraction of the handle by pressing, and make the handle extend or retract to a fixed position.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A telescopic showerhead comprises a showerhead body, wherein the showerhead body is provided with a water outlet cover and a water inlet pipe extending along a first direction; further comprising a telescopic sleeve and a pressing assembly; the outer wall of the water inlet pipe is provided with a first limiting groove and a second limiting groove along the first direction; the telescopic sleeve is arranged outside the water inlet pipe and is suitable for slidingly cooperating with the water inlet pipe in a non-rotating manner along the first direction; the pressing assembly forms a lever-cooperating relationship with the telescopic sleeve, and comprises a positioning block extending toward the water inlet pipe; the positioning block is limitedly cooperating with the first limiting groove or the second limiting groove when the pressing assembly swings to the first position to lock the telescopic sleeve from sliding; and is disengaged from the first limiting groove or the second limiting groove when the pressing assembly swings to the second position to unlock the telescopic sleeve from sliding.

[0006] Furthermore, the pressing assembly also includes a pressing block, a rotating shaft and a pressing spring; the rotating shaft is axially perpendicular to the first direction, and is fixed to the pressing block and rotatably connected to the telescopic sleeve so that the pressing block swings relative to the telescopic sleeve; the positioning block is installed at one end of the pressing block, the pressing spring is installed on the other end of the pressing block relative to the positioning block, and the pressing spring pushes the pressing block to swing toward the position of the positioning block when not subjected to external force.

[0007] Furthermore, the positioning block is symmetrically provided with a pair of positioning pins; the pressing block is symmetrically provided with a pair of elongated pin connecting holes; each of the positioning pins is respectively inserted into the corresponding pin connecting hole, and the pin connecting hole is configured to be suitable for the positioning pin to slide inside it along its extension direction.

[0008] Furthermore, a positioning hole is provided on the telescopic sleeve; the positioning hole is configured to be adapted to the positioning block; the positioning block slides along the penetration direction of the positioning hole under the action of the side wall of the positioning hole when the pressing block swings, and slides along the extension direction of the pin shaft connection hole at the same time.

[0009] Furthermore, the telescopic sleeve is provided with a rotating shaft seat; the rotating shaft seat is provided with a rotating shaft interface; the rotating shaft interface is configured to be rotatably connected to the rotating shaft, and the rotating shaft interface is arranged at an angle.

[0010] Furthermore, the telescopic sleeve is provided with at least one guide block around the positioning hole on one side facing the pressing block; the guide block is provided with a guide slope inclined toward the positioning hole.

[0011] Furthermore, it also includes a telescopic spring; one end of the telescopic spring acts on the water inlet pipe, and the other end acts on the telescopic sleeve, and drives the water inlet pipe to extend out of the telescopic sleeve when the water inlet pipe is unlocked from the retracted state.

[0012] Furthermore, the inner side wall of the telescopic sleeve is provided with a spring abutment block protruding outward; the periphery of the spring abutment block extends toward the first direction and surrounds a spring installation cavity; the telescopic spring is installed in the spring installation cavity and one end thereof abuts against the spring abutment block; the water inlet pipe is provided with a anti-rotation groove extending along the first direction at a position corresponding to the spring abutment block.

[0013] Furthermore, it also includes a top block; the top block is placed in the anti-rotation slide groove, and one end of the top block abuts against the water inlet pipe, and the other end abuts against the telescopic spring.

[0014] Furthermore, it also includes a sealing ring; the water inlet pipe includes a pipe body and a joint; the first limit groove and the second limit groove are located on the pipe body; the joint is fixed to one end of the pipe body away from the water outlet cover, and is used for an external water inlet hose; a sealing ring groove for accommodating the sealing ring is provided on the periphery of the joint; the sealing ring abuts against the inner wall of the telescopic sleeve.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A sleeve structure is provided so that the shower head can be extended and retracted. At the same time, the positioning block is driven to move by the pressing assembly. The positioning block is engaged or disengaged with the first limiting groove and the second limiting groove, so that the water inlet pipe can be kept fixed in the extended position and the retracted position, and the retracted position can be switched by unlocking.

[0017] 2. The pressing block of the pressing assembly is used for the user to perform a pressing operation, and the rotating shaft is used to enable the pressing block to be swingably connected with the telescopic sleeve. The pressing spring pushes the pressing block to maintain a fixed position when not pressed, that is, the positioning block is maintained in a position that cooperates with the first limiting groove or the second limiting groove. In this way, the user does not need to keep pressing the pressing block after the pressing operation, and the shower can be kept in an extended or retracted state.

[0018] 3. A positioning pin is arranged on the positioning block, and a pin connection hole is arranged on the pressing block. When the positioning block moves with the pressing block, the pin connection hole can provide a movable space for the positioning block.

[0019] 4. A positioning hole that matches the size of the positioning block is set, and the positioning block is inserted into the positioning hole. Due to the presence of the pin shaft connection hole, the positioning block can realize a straight up and down movement relative to the positioning hole without swinging with the pressing block. In this way, when the positioning block forms a limiting matching relationship with the first limiting groove or the second limiting groove, the shear force of the water inlet pipe exerted on the positioning block is mainly borne by the side wall of the positioning hole, and only a small part is transmitted to the pressing block. Since the positioning hole is a structure fixedly set on the telescopic sleeve and the positioning block is matched with the positioning block, the positioning block will not be offset, and the movement of the water inlet pipe can be very firmly restricted.

[0020] 5. A rotating shaft seat is provided and the rotating shaft interface is tilted, which facilitates the installation of the pressing component and prevents the rotating shaft of the pressing component from being separated from the rotating shaft seat.

[0021] 6. A guide block is provided. When the positioning block is out of the positioning hole, the guiding inclined surface of the guide block can ensure that the positioning block is inserted into the positioning hole accurately and quickly.

[0022] 7. A telescopic spring is provided to allow the water inlet pipe to extend automatically.

[0023] 8. A spring installation cavity is provided to facilitate the installation of the telescopic spring. A non-rotation slide groove is provided on the water inlet pipe. The side wall constituting the spring installation cavity can slide in the non-rotation slide groove, so that the water inlet pipe can be non-rotatably slidably connected to the telescopic sleeve along the first direction.

[0024] 9. A top block is provided to prevent the telescopic spring from falling out of the spring installation cavity, facilitate the installation of the telescopic spring, and prevent the telescopic spring from being exposed when the water inlet pipe is extended, thereby improving the aesthetics.

[0025] 10. A joint is provided for connecting an external water inlet hose; a sealing ring is installed on the joint to provide a damping effect on the expansion and contraction of the water inlet pipe, and it is also easier to clean dirt on the inner wall of the expansion sleeve.

[0042] See also Figure 1 , Figure 1 The structure explosion diagram of an embodiment of a telescopic shower provided by the present invention is shown, which mainly includes a shower body, a telescopic sleeve 10, a pressing assembly 20, a telescopic spring 31 and a top block 32.

[0043] The shower body is provided with a water outlet cover 12 and a water inlet pipe 11 extending along a first direction.

[0044] The water outlet cover 12 is the water outlet end of the shower body, and is provided with a plurality of water outlet holes, through which water flows out. A brush extending along the water outlet direction is provided on the panel of the water outlet cover 12, and the brush can provide massage or cleaning functions for the shower.

[0045] The water inlet pipe is an internally hollow water inlet pipeline, which includes a pipe body 11 and a joint 41. One end of the pipe body 11 is connected to the water outlet cover 12 to pass water to the water outlet cover 12, and the end of the pipe body 11 away from the water outlet cover 12 is connected to the joint 41, which can be fixedly connected by welding. The joint 41 is used to connect an external water inlet hose, and external water supply can be passed into the water inlet pipe. A sealing ring groove is provided on the periphery of the joint 41, and a sealing ring 42 can be placed in the sealing ring groove.

[0046] like Figure 2 As shown, the length direction of the tube body 11 is the first direction, and the first limiting groove 111 and the second limiting groove 112 are arranged in sequence along the first direction on the outer wall of the tube body 11, the first limiting groove 111 is close to the water outlet cover 12, and the second limiting groove 112 is close to the joint 41. The first limiting groove 111 and the second limiting groove 112 are both rectangular grooves arranged horizontally, and their wide sides extend inwardly to form an inclined surface. The tube body 11 is also provided with a stop groove 113 extending along the first direction on the outer walls on both sides relative to the axial direction where the first limiting groove 111 and the second limiting groove 112 are located. The stop groove 113 is closed at one end close to the water outlet cover 12, and the other end extends to the lower end of the tube body 11 and remains open. The stop groove 113 is closed after the joint 41 is fixed to the lower end of the tube body 11.

[0047] The tube body 11 is also provided with a step portion at one end close to the water outlet cover 12, and the step surface of the step portion forms a first limiting surface. The joint 41 cooperates with the tube body 11 to form another step portion, and the step surface of the step portion forms a second limiting surface.

[0048] like Figure 3 As shown, the telescopic sleeve 10 is a cylindrical component with open upper and lower ends and a hollow interior. Its size is adapted to the pipe body 11 of the water inlet pipe so that the water inlet pipe can slide therein.

[0049] The outer wall of the telescopic sleeve 10 is provided with a protruding wall 105 near the top (i.e., near the water outlet cover 12 after assembly), the wall 105 is formed into a runway shape, and a pressing chamber 106 is formed inside the pressing chamber 106. The positioning hole 101, the guide block 102 and the rotating shaft seat 103 are provided in the pressing chamber 106.

[0050] The rotating shaft seat 103 is disposed in the middle of the pressing chamber 106 and does not contact the inner side wall of the wall 105. Instead, it is disposed on the outer side wall of the telescopic sleeve 10. The rotating shaft seat 103 is provided with a rotating shaft interface 104. Figure 6 or Figure 7 In the cross-sectional direction shown, the opening of the rotating shaft interface 104 is tilted and faces rightward relative to the vertical direction.

[0051] The positioning hole 101 is arranged on the left side of the rotating shaft seat 103 (with Figure 6 or Figure 7 ), which is a through hole that penetrates the side wall of the telescopic sleeve 10.

[0052] There are two guide blocks 102, which are respectively located on the left and right sides of the positioning hole 101. The guide blocks 102 are provided with guide slopes that are inclined from the outside to the inside toward the positioning hole 101, and the lower ends of the guide slopes are higher than the outer side walls of the telescopic sleeve 10, so that the length of the positioning hole 101 in its penetration direction is increased.

[0053] like Figure 8 As shown, the inner wall of the telescopic sleeve 10 is further provided with a spring abutment block 13 protruding outward, the periphery of the spring abutment block 13 extends toward the first direction to form a side wall, and the side wall and the spring abutment block 13 are surrounded to form a spring installation cavity 131.

[0054] The upward end surface of the telescopic sleeve 10 forms a third limiting surface, and the downward end surface of the spring abutment block 13 forms a fourth limiting surface.

[0055] like Figure 4 As shown, the pressing assembly 20 includes a pressing block 21 , a positioning block 22 , a rotating shaft 23 and a pressing spring 24 .

[0056] The pressing block 21 is a button component, which includes a pressing seat for the user to press, and a pressing member located below the pressing seat (with Figure 4 A mounting chamber (with the direction shown as the standard) is provided on the side wall of the pressing block 21. A pin connection hole 211 is provided on the side wall of the pressing block 21. The pin connection hole 211 is inclined and is a long strip-shaped through hole. There are two pin connection holes 211, which are symmetrically arranged on two opposite side walls of the pressing block 21. A rotating shaft mounting hole is provided in the middle position of the pressing block 21. The rotating shaft mounting hole is a circular through hole with an opening at the bottom, and is symmetrically arranged on the two side walls of the pressing block 21, and its opening size is smaller than its diameter. A spring positioning column extending downward is provided at the other end of the pressing block 21 relative to the pin connection hole 211.

[0057] The structure of the positioning block 22 is as follows: Figure 5 As shown, it includes a main body, and a positioning pin 221 is respectively provided at the upper position on both sides of the main body, and the two positioning pins 221 are symmetrically positioned. A clearance groove is also provided in the middle position of the positioning block 22 to facilitate the deformation of the positioning block 22.

[0058] The rotating shaft 23 includes fixed parts located on both sides and an inserting part located in the middle.

[0059] The two positioning pins 221 of the positioning block 22 are respectively inserted into the two pin holes 211 , and the size of the positioning pin 221 matches the size of the pin hole 211 , so that the positioning pin 221 can slide along the extension direction of the pin hole 211 .

[0060] The fixing parts on both sides of the rotating shaft 23 are used to match with the rotating shaft mounting holes on the pressing block 21 to fix the rotating shaft 23 to the pressing block 21 , and the plug-in part in the middle is used to plug and match with the rotating shaft interface 104 .

[0061] One end of the pressing spring 24 is sleeved on the spring positioning column, and the other end is downwardly abutted against the outer wall of the telescopic sleeve 10 .

[0062] The pressing block 21 , the positioning block 22 , and the rotating shaft 23 are all made of plastic materials, and can be connected and matched by mutual extrusion and deformation during assembly.

[0063] The following describes the assembly of the telescopic shower head provided by the present invention and the relationship between the components after assembly.

[0064] The tube body 11 of the water inlet pipe is inserted into the inner cavity of the telescopic sleeve 10, and the anti-rotation groove 113 on the tube body 11 cooperates with the spring abutment block 13 on the inner wall of the telescopic sleeve 10 and the side wall extended therefrom, so that the telescopic sleeve 10 and the water inlet pipe can achieve anti-rotation sliding cooperation.

[0065] After the tube body 11 is inserted into the inner cavity of the telescopic sleeve 10, the joint 41 is welded to the lower end of the tube body 11, and the sealing ring 42 is installed at the same time. The sizes of the joint 41 and the sealing ring 42 can make the sealing ring 42 abut against the inner wall surface of the telescopic sleeve 10, thereby ensuring the sealing effect and also making the water inlet pipe have damping when it is extended and retracted. In the actual installation process, the external water inlet hose can be connected to the joint 41.

[0066] The telescopic spring 31 is inserted into the spring installation cavity 131, and then one end of the top block 32 is abutted against the upper end of the telescopic spring 31, and the other end is abutted against the closed end of the anti-rotation slide groove 113. The lower end of the telescopic spring 31 abuts against the spring abutment block 13, and the other end abuts against the water inlet pipe through the top block 32, and its length is sufficient to be in a contracted state when the water inlet pipe is in a retracted state, and when the water inlet pipe is unlocked, it can restore its deformation and push the water inlet pipe to extend.

[0067] The rotating shaft 23 in the pressing assembly 20 is inserted into the rotating shaft interface 104 on the rotating shaft seat 103, and the positioning block 22 is inserted into the positioning hole 101, and the pressing spring 24 abuts against the outer wall of the telescopic sleeve 10. The length of the positioning block 22 is sufficient to ensure that the portion inserted into the first limiting groove 111 or the second limiting groove 112 after passing through the positioning hole 101 can still ensure the locking of the water inlet pipe.

[0068] The state where the pressing block 21 is not pressed is as follows Figure 6 As shown, at this time, the positioning block 22 extends into the first limiting groove 111 , restricting the movement of the water inlet pipe so that the water inlet pipe cannot extend from the telescopic sleeve 10 .

[0069] The state of pressing the pressing block 21 is as follows Figure 7 As shown, at this time, the positioning block 22 is disengaged from the first limiting groove 111, and the water inlet pipe is automatically extended under the action of the telescopic spring 31, and the second limiting surface on the water inlet pipe will abut against the fourth limiting surface on the telescopic sleeve 10, so that the extension length of the water inlet pipe is limited. At the same time, when the two abut, the pressing block 21 is released, and the positioning block 22 enters the second limiting groove 112. At this time, the water inlet pipe cannot be retracted either, and its position is locked.

[0070] When the positioning block 22 is in the second limiting groove 112, press the pressing block 21 again, and then push the water inlet pipe to retract into the telescopic sleeve 10 until the first limiting surface on the water inlet pipe abuts against the third limiting surface on the telescopic sleeve 10. At this time, release the pressing block 21, and the positioning block 22 will re-enter the first limiting groove 111, thereby locking the water inlet pipe.

[0071] During the movement of the positioning block 22, it always maintains a straight up and down movement. The pressing block 21 swings relative to the telescopic sleeve 10. If the positioning block 22 is fixed on the pressing block 21, its movement trajectory is arc-shaped, which results in the positioning block 22 requiring a larger movement space and being unable to fit the positioning hole 101 perfectly. In the present invention, the positioning block 22 is movably connected to the pressing block 21. The positioning block 22 can be restricted by the side wall of the positioning hole 101 after being adapted to the positioning hole 101. The pressing block 21 plays a role in driving the positioning block 22 to move up and down. During the up and down movement of the positioning block 22, the positioning pin 221 will slide along the pin connection hole 211. Through the above structure, when the positioning block 22 is in the position of locking the water inlet pipe, a large part of the shear force it is subjected to will be borne by the side wall of the positioning hole 101, and the positioning hole 101 has a certain length in its penetration direction, so the positioning block 22 can better disperse the shear force on the side wall of the positioning hole 101, that is, the shear force of the water inlet pipe on the positioning block 22 will be borne by the telescopic sleeve 10 as a whole, so the stability of the locking of the water inlet pipe can be guaranteed.

[0072] The telescopic shower head provided by the present invention is provided with a pressing assembly so that the shower head body can be telescoped in the telescopic sleeve and locked in a preset position, thereby realizing the change of the shower head length and improving the user experience.

[0073] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
