[0002] Showers, spray guns, etc. are commonly used water outlet devices. These devices are generally connected to the faucet, and the water outlet is controlled by the switch on the faucet. When in use, there is a certain distance between the water outlet device and the switch. In some cases, such as when washing your hair, you cannot open your eyes due to shampoo and other reasons, and you need to grope for the switch and control the water supply to stop. Or in winter, after adjusting the water temperature through the switch, when you need to stop the water to apply shampoo or shower gel, if you turn off the water directly, you need to readjust the water temperature when you turn it on again. In order to solve the above-mentioned inconvenience, more and more water outlet devices are equipped with a water pause function. The water can be cut off by pressing or pushing and pulling the switch on the water outlet device. The water supply is not completely cut off.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Example

[0034] Combination Figures 1 to 12The present embodiment provides a push button water pause mechanism, comprising a water inlet pipe 1 and a sliding tube 2 sleeved on the outside of the water inlet pipe 1, wherein the water inlet pipe 1 is provided with a water inlet 111, a water outlet 121, a water inlet channel 11, a water outlet channel 12 and a water through hole 13, the water inlet channel 11 is communicated with the water inlet 111, and the water outlet channel 12 is communicated with the water outlet 121; the sliding tube 2 has a water sealing portion 21 and a water through cavity 22, and the push button 3 is driven in an operable manner to drive the sliding tube 2 to move between a first position and a second position along the axial direction of the water inlet pipe 1, so that the water inlet 111 and the water outlet 121 are separated by the water sealing portion 21 or connected by the water through cavity 22, and when the water inlet 111 and the water outlet 121 are separated, the water flows only into the water outlet channel 12 from the water through hole 13 to realize the water pause function.

[0035] Exemplarily, the user manually turns or pushes the push button 3 to drive the sliding tube 2 to move along the axial direction of the water inlet pipe 1, thereby switching between the first position and the second position. When the sliding tube 2 is in the first position, the water sealing part 21 separates the water inlet 111 from the water outlet 121, and the water flow in the water inlet channel 11 can only enter the water outlet channel 12 from the water hole 13, which is a suspended water state; when the sliding tube 2 is in the second position, the water inlet 111 and the water outlet 121 are connected through the water cavity 22, and the water flow can flow from the water inlet channel 11 through the water inlet 111, the water cavity 22 and the water outlet 121 into the water outlet channel 12 in sequence, which is a normal water outlet state. Among them, the size of the water hole 13 is much smaller than the size of the water inlet 111. When in the suspended water state, the water flow in the water outlet channel 12 is close to being cut off, but not completely cut off, and is a state of a small amount of water drops flowing. In the normal water outlet state, there is water flow from the water outlet 121 and water flow from the water hole 13 in the water outlet channel 12, and the water flow rate is large at this time.

[0036] It should be noted that in this embodiment, the push button 3 drives the sliding tube 2 to move along the axial direction of the water inlet pipe 1 to switch to the water pause state, with fewer parts and a simple structure, which can reduce the space occupied by the water pause mechanism to adapt to different water outlet devices. At the same time, fewer parts can reduce assembly and parts costs and ensure stability after assembly.

[0037] In a preferred embodiment, the water inlet channel 11 and the water outlet channel 12 are both arranged along the axial direction of the water inlet pipe 1, the water inlet 111 is arranged on the side wall of the water inlet channel 11, and the water outlet 121 is arranged on the side wall of the water outlet channel 12; a partition is arranged in the water inlet pipe 1 to separate the water inlet channel 11 and the water outlet 12, and the water hole 13 is arranged on the partition. The coaxial arrangement of the water inlet channel 11 and the water outlet channel 12 can reduce the radial dimension of the water inlet pipe 1, and a thread can be arranged at the end of the water inlet channel 11 to connect with an external pipeline. The sliding tube 2 is sleeved on the outside of the water inlet pipe 1. When it moves to the first position, the water sealing part 21 is located on the side wall between the water inlet 111 and the water outlet 121, and is sealed with the side wall, so that the water inlet 111 is separated from the water outlet 121. When it moves to the second position, the water passage cavity 22 is aligned and connected with the water inlet 111 and the water outlet 121.

[0038] Preferably, the cross-sectional size of the water inlet 111 decreases from the end of the water inlet channel 11 to the end of the water outlet channel 12 along the axial direction of the water inlet pipe 1, so as to prevent the phenomenon of large pressure fluctuation and vibration caused by the rapid change of flow, that is, to reduce water hammer. Similarly, the water hole 13 has a water passing section 131 and a straight flow section 132 arranged in sequence from the end of the water inlet channel 11 to the end of the water outlet channel 12, and the cross-sectional size of the water passing section 131 decreases from the end of the water inlet channel 11 to the end of the water outlet channel 12, wherein the setting of the water passing section 131 is also to reduce water hammer and the noise generated by the change of flow.

[0039] On the basis of the above-mentioned embodiment, in an optional embodiment of the utility model, the sliding tube 2 is configured to be limited by the outer shell 4, a guide groove is provided on the outer wall of the sliding tube 2, and a guide portion 41 is provided on the inner wall of the outer shell 4 corresponding to the guide groove 23, and the guide groove 23 is adapted to the guide portion 41, so that the sliding tube 2 can move along the axial direction of the water inlet pipe 1. For example, the outer shell 4 is tubular, and the outer wall of the sliding tube 2 is provided with at least two guide grooves 23 equidistantly along its circumferential direction, and the extension direction of the guide grooves 23 is the same as the axial direction of the water inlet pipe 1. The outer shell 4 is provided on the outer side of the sliding tube 2, and the inner wall thereof is provided with a guide portion 41 corresponding to the guide groove 23 protruding inwardly, so that the sliding tube 2 can move along the axial direction of the water inlet pipe 1 after receiving the thrust of the push button 3.

[0040] Preferably, a boss 14 is provided extending outward from the end of the water inlet channel 11 of the water inlet pipe 1, and a plurality of first mounting holes 141 are provided in an array along the circumferential direction on the boss 14, and a second mounting hole 42 is provided in the housing 4 corresponding to each first mounting hole 141, and the first mounting hole 141 is connected to the second mounting hole 42 via a fastener. In one embodiment, one end of the housing 4 is connected to the end of the water inlet channel 11 of the water inlet pipe 1, and the other end is connected to the end of the water outlet channel 12 of the water inlet pipe 1, and a plurality of sealing grooves are provided on the outer wall of the water inlet pipe 1, and an O-ring is provided in each sealing groove to seal with the sliding pipe 2 and the housing 4.

[0041] In other embodiments, both ends of the sliding tube 2 are limited by the boss 14 or the step surface 43 of the housing 4 during the movement. Specifically, the housing 4 is provided with a moving cavity 44 and a water outlet cavity 45 connected to the moving cavity 44, wherein the size of the water outlet cavity 45 is smaller than the size of the moving cavity 44, so that the step surface 43 is formed at the connection between the moving cavity 44 and the water outlet cavity 45, the sliding tube 2 is arranged in the moving cavity 44, and the boss 14 of the water inlet pipe 1 is connected to the other end of the moving cavity 44 away from the water outlet cavity 45, so that the sliding tube 2 is limited by the boss 14 or the step surface 43 when moving in the moving cavity 44. For example, when the sliding tube 2 moves to the first position, one end of the sliding tube 2 abuts against the step surface 43 for limitation, and when the sliding tube 2 moves to the second position, the other end of the sliding tube 2 is limited by the boss 14.

[0042] Preferably, one end of the push button 3 is connected to the sliding tube 2, and the other end passes through the clearance groove 46 of the shell 4 and is exposed to the user side. The clearance groove 46 is provided on the side wall of the movable cavity 44. Furthermore, the end surface of the shell 4 for connecting with the boss 14 is provided with a limit portion 47 protruding upward, and the boss 14 is provided with a slot 142 corresponding to the limit portion 47. During assembly, the limit portion 47 is engaged with the slot 142 to ensure that the orientation of the clearance groove 46 is accurate and the clearance groove 46 is positioned. Then, the first mounting hole 141 and the second mounting hole 42 are locked with screws, so that the shell 4 is connected and fixed to the water inlet pipe 1.

[0043] Based on the above embodiments, in an optional embodiment of the present invention, referring to Fig.10 The sliding tube 2 includes an inner tube 211 and an outer tube 24 which are fixedly connected. The inner tube 211 is provided with a water sealing portion 21. The concave cavity on the outer tube 24 is used to form a water passage cavity 22. The water sealing portion 21 includes a groove provided on the inner wall of the inner tube 211 and a sealing ring 212 disposed in the groove. The inner tube 211 is configured to be fixed to the outer tube 24 by ultrasonic welding. During assembly, the sealing ring 212 is first placed in the groove, and then the inner tube 211 and the outer tube 24 are fixed by welding. This configuration can facilitate the installation of the sealing ring 212 and avoid the situation where the sealing ring 212 is located in the middle of the outer tube 24 and is difficult to install.

[0044] A water outlet device is also provided, including a water outlet body and a push button water pause mechanism as described in any of the above embodiments, which is adapted and connected to the water outlet body. The water outlet body can be a shower, a spray gun, a pull-out faucet, etc., without specific limitation. Exemplarily, the water outlet body is a shower, and the push button water pause mechanism is sleeved in the handle of the shower. The water inlet channel 11 end of the water inlet pipe 1 is provided with a thread, which is exposed to the water outlet body and is used to connect with the shower hose. The water outlet cavity 45 end of the housing 4 is provided with a thread, which is used to connect with the internal pipeline of the shower. By applying force to the push button 3 to move the sliding tube 2, the switching between pausing water and normal water outlet is realized, and a water distribution plate can be set inside the shower to realize multi-functional water distribution, so that when the water is discharged normally, the water outlet form can be switched by turning the shower cover. It should be mentioned that in this embodiment, no matter what form the shower water outlet is in, it can be directly switched to pausing water by turning or pushing the push button 3, which is convenient and quick.
