Description

Technical Field

[0001] The invention relates to a pull-out switch shower head. Background Art

[0002] As the name suggests, pull-out kitchen showers are mostly used in kitchens. They are pull-out and have a certain extension distance. They are practical, convenient and flexible. Before using a traditional pull-out kitchen shower, you need to turn on the water by turning the knob or switch on the shower, and then pull the shower out for use. After use, you need to turn off the water by turning the knob or switch. This operation method brings inconvenience to consumers and needs to be improved urgently. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a pull-out switch shower head, comprising a support pipe, a water inlet hose, a shower head body, a drive assembly and a limit assembly.

[0004] One end of the water inlet hose passes through the support pipe and is connected to the water outlet valve assembly in the shower body.

[0005] The driving assembly is mounted on the supporting pipe, the water inlet hose and / or the shower body.

[0006] The limiting assembly is installed on the water inlet hose, the shower body and / or the supporting pipe.

[0007] When the shower body is connected to the support pipe or the water is turned off, the relative position of the shower body and the support pipe is the initial position.

[0008] The user pulls the shower body and the water inlet hose from the initial position, and after the driving assembly drives the water inlet hose to move a predetermined distance relative to the shower body, the water inlet hose drives the water outlet valve assembly to open the water path in the shower body and enter the water outlet state. At this time, the limit assembly is in the first position to lock the relative position of the water inlet hose and the shower body.

[0009] The user releases the shower body and the water inlet hose, and the water inlet hose is acted upon by the counterweight or the reset mechanism installed on the water inlet hose, and the shower body returns to the initial position, and the limit assembly is in the second position and unlocks the shower body and the water inlet hose, and the shower body and the water inlet hose return to their relative positions in the water-off state.

[0010] It can be seen that when the pull-out switch shower head proposed in the present invention is used, when the shower head body is pulled out, the driving assembly opens the water outlet valve assembly, thereby opening the water path, and water flows from the water inlet hose through the water outlet valve assembly, and the shower head discharges water. At the same time, the limit assembly enters the first position to lock the water outlet state. When the user releases the shower head body, the shower head body is reset, the driving assembly closes the water outlet valve assembly, the limit assembly enters the second position, and the shower head turns off water.

[0011] Furthermore, the limiting assembly includes a positioning card, a resetting push piece and a limiting card.

[0012] The positioning fixture comprises a bottom end and a triangular head, the head having an inclined surface. The bottom end of the positioning fixture is fixed or fixedly installed via an elastic member on one end of the water inlet hose extending into the shower body, and the head points to the support tube.

[0013] The resetting and pushing member is fixedly mounted on the end of the support tube and faces the inclined surface of the head of the positioning clamp.

[0014] The limit clamp is fixedly arranged in the shower body and is located between the bottom end of the positioning clamp and the reset push piece. A pre-tightened elastic piece is arranged between the bottom end of the positioning clamp and the limit clamp.

[0015] Pull the shower body to enter the water outlet state. When the limit assembly enters the first position, the water inlet hose drives the positioning card to compress the elastic member, and the head of the positioning card is stuck on the limit assembly, that is, the water inlet hose and the shower body are locked in a state of relative separation by a predetermined distance. At this time, the limit assembly enters the first position, that is, the head of the positioning card is located in the first position.

[0016] When the shower body is released, the shower body resets and presses against the support tube at an instant, the reset push piece contacts and squeezes the head of the positioning card, the positioning card or the elastic piece is deformed, the head of the positioning card withdraws from the limit card, the limit assembly enters the second position, and the water inlet hose and the shower body approach each other again, thereby closing the water outlet valve assembly.

[0017] The present invention locks the water outlet state by clamping the positioning clamp on the limiting clamp, and closes the water outlet state by squeezing the positioning clamp out of the limiting clamp through the resetting push piece, thereby forming two states of water off or water on.

[0018] The number of the positioning clamp, the limiting clamp and the resetting and pushing member is consistent, and there is at least one of each.

[0019] Furthermore, an annular limit clamp is installed in the shower body, and a downward end of the inner circle of the limit clamp is chamfered.

[0020] A tubular spring support is provided on a fixed sleeve of a section of the water inlet hose that passes through the limit clamp and extends into the shower body. The bottom end of the positioning clamp is fixed or fixedly installed on the periphery of the spring support through an elastic member, and the inclined surface of the head of the positioning clamp faces the chamfer of the limit clamp.

[0021] The end of the spring support member away from the shower body extends out of the support platform toward the periphery. The elastic member is a spring, which is pre-tightened on the spring support member, one end of the spring abuts against the support platform, and the other end abuts against the limit clamp. When the limit assembly enters the first position, the water inlet hose drives the positioning clamp to compress the spring, and the head of the positioning clamp slides along the chamfer of the limit clamp, deforms, and is clamped into the inner ring of the limit clamp.

[0022] The pre-tightened spring keeps the limit card and the positioning card in close fit without loosening, and when the head of the positioning card is inserted into the inner ring of the limit card, the head of the positioning card can press the top surface of the limit card by the force of the spring.

[0023] Furthermore, the position limiting assembly includes a first bracket, which is annular and fixedly mounted on the end of the support tube, and a chamfer or arc surface is provided at one end of the inner ring of the first bracket facing downward to form the reset push member. When the position limiting assembly enters the second position, the chamfer or arc surface of the first bracket contacts and squeezes the inclined surface of the head of the positioning clamp, the positioning clamp or the elastic member is deformed, and the head of the positioning clamp exits the position limiting clamp.

[0024] Furthermore, the driving assembly includes a body rack, a gear and a hose rack. The gear is rotatably mounted in the gap between the support tube and the water inlet hose and close to the outlet of the support tube. The body rack is fixedly mounted in the shower body and points to the gear. The hose rack is fixedly mounted on the water inlet hose close to the outlet of the support tube; when the shower body is in the initial position, the body rack is inserted into the gap between the gear and the support tube and meshed, and the hose rack is also meshed with the gear.

[0025] When the user pulls the shower body and the water inlet hose from the initial position, the body rack moves downward with the shower body and drives the gear to rotate. The rotating gear drives the hose rack on the other side to move upward, and the upwardly moved hose rack drives the water inlet hose to move upward, and the upwardly moved water inlet hose drives the head of the positioning clamp to move upward. When the body rack is disengaged from the gear, the water inlet hose has moved a certain distance relative to the shower body, the water outlet valve assembly is opened, and the shower turns on and water flows out. At the same time, the head of the positioning clamp is also stuck in the inner ring of the limit clamp, and the limit assembly enters the first position from the second position to lock the water outlet state.

[0026] When the user releases the shower body, the shower body shrinks and resets under the action of the reset force. At the moment the shower body contacts the support tube, the reset push piece squeezes the positioning card, and the positioning card withdraws from the limit card. The head of the positioning card enters the second position again. At this time, the body rack and the hose rack engage with the gear again, and the body rack drives the gear to reverse, and the reversed gear drives the hose rack to move toward the shower body, and the water inlet hose and the shower body approach each other again, thereby closing the water outlet valve assembly.

[0027] Furthermore, the gear is mounted on the first bracket, and a clearance groove is provided on the periphery of the first bracket.

[0028] A second bracket is fixedly installed in the shower body, and the body rack is arranged on the periphery of the second bracket aligned with the clearance groove of the first bracket.

[0029] A third bracket is installed at a section of the water inlet hose between the first bracket and the end of the shower body, and the third bracket is tubular. The hose rack is arranged on the upper side of the circumference of the third bracket.

[0030] Furthermore, the shower body is provided with an embedding groove at one end facing the support tube, the bottom of the embedding groove is the limiting clamp, the second bracket is fixedly installed at the bottom of the limiting clamp, and the body rack passes through the through hole provided around the limiting clamp and is spaced apart from the inner wall of the embedding groove.

[0031] When the shower body is in the initial position, the end of the support tube is inserted into the embedding groove, the body rack is inserted into the yield groove of the first bracket, and docked with the gear; the third bracket is inserted into the inner ring of the first bracket, and the hose rack is docked with the gear.

[0032] Furthermore, the driving assembly includes a body magnet, a metal seesaw and a hose magnet, and the body magnet and the hose magnet are of opposite polarities.

[0033] The middle part of the metal seesaw is hingedly installed and can be rotatably installed in the gap between the support pipe and the water inlet hose and close to the outlet of the support pipe.

[0034] The body magnet is fixedly installed in the shower body and points to the metal seesaw.

[0035] The hose magnet is fixedly mounted on the outlet of the water inlet hose close to the support pipe.

[0036] When the shower body is located at the initial position, the body magnet is close to one side of the metal seesaw close to one end of the support tube, and the hose magnet is located at the other side of the metal seesaw close to one end of the water inlet hose.

[0037] When the user pulls the shower body and the water inlet hose from the initial position, the body magnet moves downward with the shower body and absorbs the metal seesaw to rotate or remain stationary, thereby resisting the hose magnet on the other side to prevent the hose magnet from moving downward. The hose magnet is driven to move upward, and the upward-moving hose tooth magnet drives the water inlet hose to move upward, and the upward-moving water inlet hose drives the head of the positioning card to move upward. When the body magnet is separated from the metal seesaw by a certain distance, it cannot generate sufficient adsorption force on the metal seesaw. At this time, the water inlet hose has moved a certain distance relative to the shower body, opening the water outlet valve assembly, and the shower is turned on to discharge water. At the same time, the positioning card is clamped into the inner ring of the limit card, and the limit assembly enters the first position from the second position to lock the water outlet state.

[0038] When the user releases the shower body, the shower body shrinks and resets under the action of the reset force. At the moment the shower body contacts the support tube, the reset push piece squeezes the positioning card, and the positioning card withdraws from the limit card. The head of the positioning card enters the second position again. At this time, the body magnet and the hose magnet attract the metal seesaw again, and the body magnet drives the metal seesaw to reverse. The reversed metal seesaw drives the hose magnet to move toward the shower body, and the water inlet hose and the shower body approach each other again, thereby closing the water outlet valve assembly.

[0039] Furthermore, the metal seesaw is mounted on the first bracket, and a clearance groove is provided on the periphery of the first bracket.

[0040] A second bracket is fixedly installed in the shower body, and the body magnet is arranged on the periphery of the second bracket aligned with the clearance groove of the first bracket. An embedding groove is arranged on one end of the shower body facing the support tube, and the bottom of the embedding groove is the limiting clamp. The second bracket is fixedly installed on the bottom of the limiting clamp, and the body magnet passes through the through hole arranged on the periphery of the limiting clamp and is spaced from the inner wall of the embedding groove.

[0041] A third bracket is installed at a section of the water inlet hose between the first bracket and the end of the shower body, and the third bracket is tubular. The hose magnet is arranged on the upper side of the circumference of the third bracket.

[0042] When the shower body is in the initial position, the end of the support tube is inserted into the embedding groove, the body magnet is inserted into the yield groove of the first bracket, and docked with the metal seesaw; the third bracket is inserted into the inner ring of the first bracket, and the hose magnet docks with the gear.

[0043] Furthermore, the shower body further comprises a switch valve and a switch button, wherein the switch valve is connected to the water outlet end of the water inlet hose, and the switch button is connected to the valve stem of the switch valve and extends to the outside of the shower body. Through the switch valve and the switch button, water can be turned on and off without pulling the shower body.

[0044] Furthermore, the water inlet hose is provided with a reset weight block or a reset component.

[0045] Furthermore, the water outlet valve assembly includes a water trough, the inner diameter of which is equal to the outer diameter of the water outlet end of the water inlet hose, and the water outlet end of the water inlet hose extends into the water trough. A water outlet hole is provided on the side wall of the water trough, and the water outlet hole is connected to the water outlet of the shower body. When the water is in the water-off state, the water inlet hose exceeds the water outlet hole, and the side wall of the water inlet hose blocks the water outlet hole. When the water is in the water outlet state, the water inlet hose gives way to the water outlet hole, and water flows out of the water outlet hole.

[0046] Furthermore, the bottom of the water channel is connected to the water inlet channel of the switch valve, and the water outlet channel of the switch valve is connected to the water outlet of the shower body. Pressing the switch button arranged outside the shower body, and then pressing the valve stem of the switch valve, the switch valve is opened or closed.

[0047] From the above description of the present invention, it can be seen that the present invention provides a driving assembly and a limiting assembly, so that when the user pulls the shower body, the driving assembly and the limiting assembly can be driven by the pulling action, thereby opening the water path through the driving assembly, and then locking the water outlet state of the water path through the limiting assembly. When the user releases the shower body, the shower body can contract to drive the driving assembly to overcome the limiting assembly and close the water path. It can be seen that during use, the user saves the actions of turning on and off the water, and it is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0064] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0065] See also Figures 1 to 4A pull-out switch shower head comprises a supporting pipe 1, a water inlet hose 2, a shower head body 3, a driving assembly 4 and a limiting assembly 5.

[0066] One end of the water inlet hose 2 passes through the support pipe 1 and is connected to the water outlet valve assembly 31 in the shower body 3 .

[0067] The driving assembly 4 is mounted on the supporting tube 1 , the water inlet hose 2 and the shower body 3 .

[0068] The limiting assembly 5 is installed on the supporting tube 1 , the water inlet hose 2 and the shower body 3 .

[0069] The water outlet valve assembly 31 includes a water groove 311, the inner diameter of which is equal to the outer diameter of the water outlet end of the water inlet hose 2, and the water outlet end of the water inlet hose 2 extends into the water groove 311. The side wall of the water groove 311 is provided with a water outlet hole 312, and the water outlet hole 312 is connected to the water outlet of the shower body 3. When in the water-off state, the water inlet hose 2 exceeds the water outlet hole 312, and the side wall of the water inlet hose 2 blocks the water outlet hole 312. When in the water outlet state, the water inlet hose 2 gives way to the water outlet hole 312, and water flows out of the water outlet hole 312.

[0070] The water inlet hose 2 is provided with a reset weight block or a reset assembly, and the support pipe 1 is installed through a mounting seat, and a water circuit main switch can also be arranged on the mounting seat.

[0071] When the shower body 3 is connected to the support tube 1 or the water is turned off, the relative position of the shower body 3 and the support tube 1 is the initial position.

[0072] The user pulls the shower body 3 and the water inlet hose 2 from the initial position, and after the driving assembly 4 drives the water inlet hose 2 to move a predetermined distance relative to the shower body 3, the water inlet hose 2 drives the water outlet valve assembly 31 to open the water path in the shower body 3 and enter the water outlet state. At this time, the limit assembly 5 is in the first position to lock the relative position of the water inlet hose 2 and the shower body 3.

[0073] The user releases the shower body 3 and the water inlet hose 2, and the water inlet hose 2 is acted upon by the counterweight or the reset mechanism installed on the water inlet hose 2, and the shower body 3 returns to the initial position, and the limit assembly 5 is in the second position and unlocks the shower body 3 and the water inlet hose 2, and the shower body 3 and the water inlet hose 2 return to the relative position of the water-off state.

[0074] It can be seen that when the pull-out switch showerhead proposed in the present invention is used, when the showerhead body 3 is pulled out, the driving assembly 4 opens the water outlet valve assembly 31, thereby opening the water path, and water flows from the water inlet hose 2 through the water outlet valve assembly 31, and the showerhead discharges water. At the same time, the limit assembly 5 enters the first position to lock the water outlet state. When the user releases the showerhead body 3, the showerhead body 3 is reset, the driving assembly 4 closes the water outlet valve assembly 31, and the limit assembly 5 enters the second position, and the showerhead turns off the water.

[0075] The limiting assembly 5 and the driving assembly 4 are described in detail below.

[0076] See also Figure 5 and Figure 6 In this embodiment, the position limiting assembly 5 includes a reset push member 51, a positioning clamp 52 and a position limiting clamp 53. The number of the positioning clamp 52, the position limiting clamp 53 and the reset push member 51 is the same, and each of them is at least one.

[0077] The head of the positioning clamp 52 is triangular and has an inclined surface. The bottom end of the positioning clamp 52 is fixed or fixedly installed through an elastic member on one end of the water inlet hose 2 extending into the shower body 3 , and the head points to the support tube 1 .

[0078] The resetting and pushing member 51 is fixedly mounted on the end of the support tube 1 and faces the inclined surface of the head of the positioning clamp 52 .

[0079] The limit clamp 53 is fixedly disposed in the shower body 3 and is located between the bottom end of the positioning clamp 52 and the reset push member 51 . A pre-tightened elastic member is provided between the bottom end of the positioning clamp 52 and the limit clamp 53 .

[0080] When the shower body 3 is pulled to enter the water outlet state and the limit assembly 5 enters the first position, the water inlet hose 2 drives the positioning clamp 52 to compress the elastic member, and the head of the positioning clamp 52 is clamped on the limit clamp 53, that is, the water inlet hose 2 and the shower body 3 are locked in a state of relative separation of a predetermined distance. At this time, the limit assembly 5 enters the first position, that is, the head of the positioning clamp 52 is located in the first position.

[0081] When the shower body 3 is released, the shower body 3 is reset to press against the support tube 1 for an instant, the reset push member 51 contacts and squeezes the head of the positioning clamp 52, the positioning clamp 52 or the elastic member is deformed, the head of the positioning clamp 52 withdraws from the limiting clamp 53, the limiting assembly 5 enters the second position, and the water inlet hose 2 and the shower body 3 approach each other again, thereby closing the water outlet valve assembly.

[0082] In the present invention, the positioning card 52 is clamped on the limiting card 53 to lock the water outlet state, and the positioning card 52 is squeezed out of the limiting card 53 by the resetting push member 51 to close the water outlet state, thereby forming two states of water off or water on.

[0083] In this embodiment, the limiting clamp 53 is annular and installed in the shower body 3. The downward end of the inner circle of the limiting clamp 53 is chamfered.

[0084] A tubular spring 22 support 21 is fixedly sleeved on a section of the water inlet hose 2 that passes through the limit clamp 53 and extends into the shower body 3 . The bottom end of the positioning clamp 52 is mounted on the periphery of the spring 22 support 21 , and the inclined surface of the head of the positioning clamp 52 faces the chamfer of the limit clamp 53 .

[0085] The end of the spring 22 support member 21 away from the shower body 3 extends out of the support platform. The elastic member is a spring 22, which is pre-tightened on the spring 22 support member 21, and one end of the spring 22 abuts against the support platform, and the other end abuts against the limit clamp 53. When the limit assembly 5 enters the first position, the water inlet hose 2 drives the positioning clamp 52 to compress the spring 22, and the head of the positioning clamp 52 slides along the chamfer of the limit clamp 53, deforms, and is clamped into the inner ring of the limit clamp 53.

[0086] The pre-tightened spring 22 keeps the limit card 53 and the positioning card 52 in close fit without loosening, and when the head of the positioning card 52 is inserted into the inner ring of the limit card 53, the head of the positioning card 52 can press the top surface of the limit card 53 by the force of the spring 22.

[0087] See also Figure 7 of Fig. 9 The position-limiting assembly 5 includes a first bracket 54, which is annular and fixedly mounted on the end of the support tube 1, and an inner ring of the first bracket 54 is provided with an arc surface at one end facing downward to form the reset push member 51. When the position-limiting assembly 5 enters the second position, the chamfer or arc surface of the first bracket 54 contacts and presses the inclined surface of the head of the positioning clamp 52, the positioning clamp 52 or the elastic member is deformed, and the head of the positioning clamp 52 exits the position-limiting clamp 53.

[0088] In this embodiment, the driving assembly 4 includes a body rack 41, a gear 42 and a hose rack 43. The gear 42 is rotatably mounted in the gap between the support tube 1 and the water inlet hose 2, and is close to the outlet of the support tube 1. The body rack 41 is fixedly mounted in the shower body 3 and points to the gear 42. The hose rack 43 is fixedly mounted on the water inlet hose 2 near the outlet of the support tube 1. When the shower body 3 is in the initial position, the body rack 41 is inserted into the gap between the gear 42 and the support tube 1 and meshed, and the hose rack 43 is also meshed with the gear 42.

[0089] Preferably, the gear 42 is mounted on the first bracket 54 , and a clearance groove is provided on the periphery of the first bracket 54 .

The third bracket 23 is inserted into the inner ring of the first bracket 54, and the hose rack 43 is docked with the gear 42.

[0094] See also Figure 8 to Figure 9When the user pulls the shower body 3 and the water inlet hose 2 from the initial position, the body rack 41 moves downward with the shower body 3 and drives the gear 42 to rotate. The rotating gear 42 drives the hose rack 43 on the other side to move upward, and the upwardly moved hose rack 43 drives the water inlet hose 2 to move upward, and the upwardly moved water inlet hose 2 drives the head of the positioning clamp 52 to move upward. When the body rack 41 is disengaged from the gear 42, the water inlet hose 2 has moved a certain distance relative to the shower body 3, the water outlet valve assembly 31 is opened, and the shower is turned on and water flows out. At the same time, the head of the positioning clamp 52 is also stuck in the inner ring of the limit clamp 53, and the limit assembly 5 enters the first position from the second position to lock the water outlet state.

[0095] See also Figures 7 to 9 When the user releases the shower body 3, the shower body 3 shrinks and resets under the action of the reset force. At the moment when the shower body 3 contacts the support tube 1, the reset push member 51 squeezes the positioning clamp 52, and the positioning clamp 52 withdraws from the limit clamp 53. The head of the positioning clamp 52 enters the second position again. At this time, the body rack 41 and the hose rack 43 engage the gear 42 again, and the body rack 41 drives the gear 42 to reverse. The reversed gear 42 drives the hose rack 43 to move toward the shower body 3, and the water inlet hose 2 and the shower body 3 approach each other again, thereby closing the water outlet valve assembly.

[0096] In other embodiments, see Figure 10 to Figure 13 The driving assembly 4 includes a body magnet 44, a metal seesaw 45 and a hose magnet 46, and the body magnet 44 and the hose magnet 46 are opposite magnets.

[0097] The middle part of the metal rocker plate 45 is hingedly installed and can be rotatably installed in the gap between the support pipe 1 and the water inlet hose 2 and close to the outlet of the support pipe 1.

[0098] The body magnet 44 is fixedly installed in the shower body 3 and points to the metal rocker plate 45 .

[0099] The hose magnet 46 is fixedly mounted on the outlet of the water inlet hose 2 close to the support tube 1 .

[0100] When the shower body 3 is at the initial position, the body magnet 44 is close to one side of the metal rocker plate 45 close to one end of the support tube 1 , and the hose magnet 46 is located at the other side of the metal rocker plate 45 close to one end of the water inlet hose 2 .

[0102] The second bracket 32 ​​is fixedly installed in the shower body 3, and the body magnet 44 is arranged on the periphery of the second bracket 32 ​​aligned with the clearance groove of the first bracket 54. The shower body 3 is provided with an embedding groove at one end facing the support tube 1, and the bottom of the embedding groove is the limiting clamp 53. The second bracket 32 ​​is fixedly installed at the bottom of the limiting clamp 53, and the body magnet 44 passes through the through hole arranged on the periphery of the limiting clamp 53 and is spaced from the inner wall of the embedding groove.

[0103] A third bracket 23 is installed at a section of the water inlet hose 2 between the first bracket 54 and the end of the shower body 3. The third bracket 23 is tubular. The hose magnet 46 is provided on the upper side of the circumference of the third bracket 23.

[0104] When the shower body 3 is in the initial position, the end of the support tube 1 is inserted into the embedding groove, the body magnet 44 is inserted into the yielding groove of the first bracket 54, and docked with the metal rocker 45; the third bracket 23 is inserted into the inner ring of the first bracket 54, and the hose magnet 46 is docked with the gear 42.

[0105] When the user pulls the shower body 3 and the water inlet hose 2 from the initial position, the body magnet 44 moves downward with the shower body 3 and absorbs the metal rocker 45 to rotate or remain stationary, thereby resisting the hose magnet 46 on the other side to prevent the hose magnet 46 from moving downward, and driving the hose magnet 46 to move upward, and the upwardly moved hose tooth magnet drives the water inlet hose 2 to move upward, and the upwardly moved water inlet hose 2 drives the head of the positioning clamp 52 to move upward. When the body magnet 44 is separated from the metal rocker 45 by a certain distance, it cannot generate sufficient adsorption force on the metal rocker 45. At this time, the water inlet hose 2 has moved a certain distance relative to the shower body 3, and the water outlet valve assembly 31 is opened, and the shower is turned on and water flows out. At the same time, the positioning clamp 52 is clamped into the inner ring of the limit clamp 53, and the limit assembly 5 enters the first position from the second position to lock the water outlet state.

[0106] When the user releases the shower body 3, the shower body 3 shrinks and resets under the action of the reset force. At the moment when the shower body 3 contacts the support tube 1, the reset push member 51 squeezes the positioning clamp 52, and the positioning clamp 52 withdraws from the limit clamp 53. The head of the positioning clamp 52 enters the second position again. At this time, the body magnet 44 and the hose magnet 46 attract the metal rocker 45 again, and the body magnet 44 drives the metal rocker 45 to reverse. The reversed metal rocker 45 drives the hose magnet 46 to move toward the shower body 3, and the water inlet hose 2 and the shower body 3 approach each other again, thereby closing the water outlet valve assembly.

[0107] In other embodiments, the shower body 3 further includes a switch valve 33 and a switch button 34, the water inlet channel of the switch valve 33 is connected to the water outlet end of the water inlet hose 2, or connected to the bottom of the water channel 311, and the switch button 34 is connected to the valve stem of the switch valve 33 and extends to the outside of the shower body 3. Through the switch valve 33 and the switch button 34, the water can be turned on and off without pulling the shower body 3.

[0108] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
