[0036] First embodiment:

[0037] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of a shower head water-stopping structure 10 provided in the first embodiment of the present invention applied to a shower head 100 . Figure 2 It is a schematic cross-sectional structure diagram of the shower water-stopping structure 10 provided in the first embodiment of the present invention when it is applied to a shower head 100. Figure 3 It is a schematic structural explosion diagram of the shower water-stopping structure 10 provided in the first embodiment of the present invention when it is applied to a shower head 100.

[0038] The first embodiment of the present invention provides a shower water-stopping structure 10, which has the functions of completely stopping water and relieving pressure when the water pressure is high, and has the characteristics of high safety and small size. The shower water-stopping structure 10 can be applied to a water pipe 500 or a shower head 100, etc.

[0039] Among them, taking the application of the shower water-stop structure 10 to the shower piece 100 as an example, the shower piece 100 includes the shower water-stop structure 10 to achieve the water-stopping function through the shower water-stop structure 10. Of course, the shower piece 100 may also include a shell 20, on which a water spray port 21 is opened. The shower water-stop structure 10 connects the water spray port 21 and the water pipe 500, and water can flow from the water pipe 500 and the shower water-stop structure 10 to the water spray port 21 in turn.

[0040] It should be noted that the shower head 100 may be a handheld shower head, or a fixed spray type or a side spray type shower head.

[0041] Since the shower head 100 adopts the shower head water-stopping structure 10 provided in the first embodiment of the present invention, the shower head 100 also has the functions of completely stopping water and relieving pressure when the water pressure is high, and has the characteristics of high safety and small size.

[0042] The structural composition, working principle and beneficial effects of the shower water-stopping structure 10 provided in the first embodiment of the present invention will be specifically described below.

[0043] See also Figure 4 , Figure 5 and Figure 6 , Figure 4 It is a schematic structural explosion diagram of the shower water-stopping structure 10 provided in the first embodiment of the present invention. Figure 5 It is a schematic structural cross-sectional view of the shower water-stopping structure 10 provided in the first embodiment of the present invention in a pressure relief state. Figure 6 The schematic cross-sectional view of the pressure relief mechanism 13 and part of the water stop rod 172 of the shower water stop structure 10 provided in the first embodiment of the present invention. Figure 5 In the figure, the direction indicated by the arrows other than the numbers is the direction of water flow.

[0044] The shower water-stopping structure 10 includes a connecting body 15, a water-stopping mechanism 17 and a pressure relief mechanism 13, wherein the connecting body 15 is disposed in the housing 20 of the shower component 100, and the connecting body 15 has a first water outlet channel 155 and a second water outlet channel 156, the first water outlet channel 155 and the second water outlet channel 156 are connected to each other, and the connecting point between the first water outlet channel 155 and the second water outlet channel 156 is a water-stopping connecting point 157, and the first water outlet channel 155 is used to communicate with the water pipe 500, and the second water outlet channel 156 is used to communicate with the water outlet 21 on the housing 20, so that water can flow from the water pipe 500, the first water outlet channel 155, the water-stopping connecting point 157 and the second water outlet channel 156 to the water outlet 21 in sequence. The water-stop mechanism 17 includes a water-stop rod 172 and a water-stop seal 171. The water-stop rod 172 can be movably arranged in the first water outlet channel 155 and the second water outlet channel 156, or in other words, the water-stop rod 172 can move along the extension direction of the first water outlet channel 155 and the second water outlet channel 156, and the water-stop seal 171 is connected to the water-stop rod 172 and is constructed to be able to seal or open the water-stop connection 157 under the drive of the water-stop rod 172 to cut off or connect the first water outlet channel 155 and the second water outlet channel 156. That is to say, by driving the water-stop seal 171 to move through the water-stop rod 172, the water-stop seal 171 can seal the water-stop connection 157 to cut off the first water outlet channel 155 and the second water outlet channel 156, or the water-stop seal 171 can open the water-stop connection 157 to connect the first water outlet channel 155 and the second water outlet channel 156.

[0045] A pressure relief channel 173 is provided inside the water stop rod 172, and the pressure relief channel 173 is connected to the first water outlet channel 155 and the second water outlet channel 156. The pressure relief mechanism 13 is arranged in the pressure relief channel 173, and the pressure relief mechanism 13 can open the pressure relief channel 173 to connect the first water outlet channel 155 and the second water outlet channel 156 to perform pressure relief work when the water pressure in the first water outlet channel 155 is greater than the preset water pressure, and seal the pressure relief channel 173 when the water pressure is less than the preset water pressure, so that the water stop mechanism 17 can stop water normally.

[0046] In this way, even when the water pressure is greater than the preset water pressure, the water-stopping mechanism 17 can be activated to cut off the first water outlet channel 155 and the second water outlet channel 156. At this time, the pressure relief mechanism 13 will automatically open the pressure relief channel 173 to connect the first water outlet channel 155 and the second water outlet channel 156, thereby avoiding excessive water pressure in the shower head 100 and the water pipe 500, improving the safety of the shower water-stopping structure 10 and the shower head 100, and allowing the water-stopping mechanism 17 to achieve complete water-stopping without worrying about components bursting due to high water pressure. In addition, by arranging the pressure relief mechanism 13 in the water-stopping rod 172, the overall volume of the shower water-stopping structure 10 can be reduced, thereby improving the user's holding experience.

[0047] It should be noted that the connecting body 15 can be a connecting structure divided into three sections, which may include a first connecting section 151, a second connecting section 152 and a third connecting section 153 which are sequentially connected by a snap ring 177 to improve the assembly convenience of the shower water stop structure 10. The water stop mechanism 17 may also include a water stop button 175 and a press switching mechanism 176. The press switching mechanism 176 is connected to one end of the water stop rod 172 extending out of the connecting body 15. Its switching principle is the same as the switching mechanism of the sliding claw and the push rod inside the push-type ballpoint pen, which will not be repeated here. The water stop button 175 is rotatably connected to the connecting body 15, and a switching inclined surface 1751 is provided on the water stop button 175. The user can push the water stop button 175 to drive the press switching mechanism 176 through the switching inclined surface 1751, thereby driving the water stop rod 172 to move along its axial direction, thereby driving the water stop seal 171 to cut off or connect the first water outlet channel 155 and the second water outlet channel 156.

[0048] Please continue reading Figure 6 The pressure relief mechanism 13 may include a pressure relief elastic member 131 and a pressure relief seal 132. The inner wall of the pressure relief channel 173 has an annular sealing surface 1722. The center line of the annular sealing surface 1722 is parallel to the extension direction of the pressure relief channel 173, and the sealing surface 1722 is arranged at an angle to the extension direction of the pressure relief channel 173. In other words, the sealing surface 1722 is arranged around the inner wall of the pressure relief channel 173, and the sealing surface 1722 is roughly the side of a virtual cone, and the generatrix of the virtual cone is roughly parallel to the extension direction of the pressure relief channel 173.

[0049] The pressure relief seal 132 and the pressure relief elastic member 131 may both be disposed in the pressure relief channel 173, and the pressure relief elastic member 131 may be connected to the inner walls of the pressure relief seal 132 and the pressure relief channel 173, respectively. The pressure relief seal 132 may be pressed on the sealing surface 1722 by the elastic force of the pressure relief elastic member 131 to seal the pressure relief channel 173, and may open the pressure relief channel 173 when the water pressure in the water pipe 500 is greater than a preset water pressure. In other words, under the action of the elastic force of the pressure relief elastic member 131, the pressure relief seal 132 has a tendency to be pressed on the sealing surface 1722, and when the water pressure in the first water outlet channel 155 is relatively small, the force of the water pressure in the first water outlet channel 155 acting on the pressure relief seal 132 is smaller than the force of the pressure relief elastic member 131 acting on the pressure relief seal 132, and the water pressure cannot push the pressure relief seal 132 away. At this time, the pressure relief seal 132 is pressed on the sealing surface 1722, and the first water outlet channel 155 and the second water outlet channel 156 are cut off, and the pressure relief mechanism 13 is in a cut-off state. When the water pressure in the first water outlet channel 155 is greater than the preset water pressure, the water pressure will push the pressure relief seal 132 from the first water outlet channel 155 to separate the pressure relief seal 132 from the sealing surface 1722, and then connect the first water outlet channel 155 and the second water outlet channel 156 through the pressure relief channel 173.

[0050] Further, the water stop rod 172 may include a first water stop section 1721 and a second water stop section 1725 connected to each other, and a first pressure relief groove 1723 communicating with the first water outlet channel 155 is provided on one end surface of the first water stop section 1721, and a second pressure relief groove 1726 communicating with the water outlet channel is also provided on one end surface of the second water stop section 1725, and the first pressure relief groove 1723 and the second pressure relief groove 1726 are detachably connected to each other, or in other words, the first water stop section 172 1 is detachably connected to one end of the second water stop section 1725 where the first pressure relief groove 1723 is located, and the openings of the first pressure relief groove 1723 and the second pressure relief groove 1726 are arranged opposite to each other, so that the internal spaces of the first pressure relief groove 1723 and the second pressure relief groove 1726 jointly form a pressure relief channel 173, and the sealing surface 1722 is the end surface of the first water stop section 1721 where the first pressure relief groove 1723 is located. In this way, by providing a split water stop rod 172, the assembly convenience of the shower water stop structure 10 is improved, and it is convenient for maintenance and production.

[0051] It should be noted that a first pressure relief port 1724 may be provided at the end of the first water stop section 1721, the first pressure relief port 1724 is close to the bottom wall of the first pressure relief groove 1723, and is communicated with the first pressure relief groove 1723, so as to connect the first pressure relief groove 1723 and the first water outlet channel 155 through the first pressure relief port 1724; and a second pressure relief port 1728 may be provided at the second water stop section 1725, the second pressure relief port 1728 is close to the bottom wall of the second pressure relief groove 1726, and is communicated with the second pressure relief groove 1726, so as to connect the second pressure relief groove 1726 and the second water outlet channel 156 through the second pressure relief port 1728.

[0052] Please continue reading Figure 6 The pressure relief seal 132 may include a pressure relief seal portion 1321 and a pressure relief guide rod 1322, and the pressure relief seal portion 1321 is arranged on the pressure relief guide rod 1322, the pressure relief seal portion 1321 is used to press the sealing surface 1722, the pressure relief guide rod 1322 is arranged along the extension direction of the pressure relief channel 173 to limit the circumferential position of the pressure relief seal portion 1321 through the pressure relief guide rod 1322, and one end of the pressure relief elastic member 131 is connected to the pressure relief guide rod 1322, and the other end is connected to the inner wall of the second pressure relief groove 1726, the pressure relief guide rod 1322 is constructed to be able to drive the pressure relief seal portion 1321 to be pressed on the sealing surface 1722 under the action of the elastic force of the pressure relief elastic member 131, in other words, the pressure relief elastic member 131 is elastically deformed and compressed between the inner wall of the second pressure relief groove 1726 and the pressure relief guide rod 1322.

[0053] Furthermore, the bottom wall of the second pressure relief groove 1726 may be provided with a first pressure relief guide hole 1727, and one end of the pressure relief guide rod 1322 is connected to the pressure relief sealing portion 1321, and the other end is slidably disposed in the first pressure relief guide hole 1727, and the circumferential position of the pressure relief guide rod 1322 is further limited by the first pressure relief guide hole 1727, thereby improving the stability of the pressure relief work of the pressure relief mechanism 13.

[0054] It should be noted that the end of the pressure relief guide rod 1322 away from the second pressure relief groove 1726 can also extend into the first pressure relief groove 1723, so that the end of the pressure relief guide rod 1322 in the first pressure relief groove 1723 can move along the side wall of the second pressure relief groove 1726, further limiting the circumferential position of the pressure relief guide rod 1322 and improving the stability of the pressure relief work of the pressure relief mechanism 13.

[0055] In addition, the pressure relief elastic member 131 can be a coil spring, and the pressure relief elastic member 131 is sleeved on the pressure relief guide rod 1322, one end of the pressure relief elastic member 131 is connected to the pressure relief guide rod 1322, and the other end is against the bottom wall of the second pressure relief groove 1726. By using the coil spring sleeved on the pressure relief guide rod 1322, the pressure relief elastic member 131 is not easy to be skewed, so that the elastic force of the pressure relief elastic member 131 stably acts on the pressure relief guide rod 1322, and the stability of the pressure relief work of the pressure relief mechanism 13 is further improved.

[0056] Furthermore, a supporting protrusion 1323 is provided on the side of the pressure relief guide rod 1322, and the pressure relief seal 132 is sleeved on the pressure relief guide rod 1322 and is located on the side of the supporting protrusion 1323 close to the sealing surface 1722, and one end of the pressure relief elastic member 131 away from the bottom wall of the second pressure relief groove 1726 is supported on the side of the supporting protrusion 1323 away from the pressure relief elastic member 131. In this way, it is equivalent to adding a gasket between the pressure relief seal 132 and the pressure relief elastic member 131, so that the pressure relief seal 1321 is not affected by the pressure relief elastic member 131, thereby improving the stability of the pressure relief work of the pressure relief mechanism 13.

[0057] See also Figure 7 , Figure 7 The schematic structural cross-sectional view of the pressure relief mechanism 13 and a part of the water stop rod 172 when the pressure relief elastic member 131 of the shower water stop structure 10 provided in the first embodiment of the present invention is a spring.

[0058] The pressure relief elastic member 131 may also be a circular spring piece with a protruding center, and a second pressure relief guide hole 1316 is opened at the center of the pressure relief elastic member 131, and the pressure relief guide rod 1322 is passed through the second pressure relief guide hole 1316, the edge of the second pressure relief guide hole 1316 is abutted against the pressure relief guide rod 1322, and the edge of the pressure relief elastic member 131 is abutted against the bottom wall of the second pressure relief groove 1726.

[0059] In this way, when the water pressure in the first water outlet channel 155 is relatively small, the force of the water pressure in the first water outlet channel 155 acting on the pressure relief seal 132 is smaller than the force of the pressure relief elastic member 131 holding the pressure relief seal 132, and the water pressure cannot push the pressure relief seal 132 away. At this time, the pressure relief seal 132 is pressed on the sealing surface 1722, and the first water outlet channel 155 and the second water outlet channel 156 are cut off. When the water pressure in the first water outlet channel 155 is greater than the preset water pressure, the water pressure will push the pressure relief seal 132 from the first water outlet channel 155, so that the pressure relief elastic member 131 is pressed down by the pressure relief guide rod 1322, and at the same time the pressure relief seal 132 is separated from the sealing surface 1722, and then the first water outlet channel 155 and the second water outlet channel 156 are connected through the pressure relief channel 173.

[0060] The working principle of the shower water-stopping structure 10 provided in the first embodiment of the present invention is:

[0061] The shower water-stopping structure 10 includes a connecting body 15, a water-stopping mechanism 17 and a pressure relief mechanism 13, wherein the connecting body 15 is disposed in the housing 20 of the shower component 100, and the connecting body 15 has a first water outlet channel 155 and a second water outlet channel 156, the first water outlet channel 155 and the second water outlet channel 156 are connected to each other, and the connecting point between the first water outlet channel 155 and the second water outlet channel 156 is a water-stopping connecting point 157, and the first water outlet channel 155 is used to communicate with the water pipe 500, and the second water outlet channel 156 is used to communicate with the water outlet 21 on the housing 20, so that water can flow from the water pipe 500, the first water outlet channel 155, the water-stopping connecting point 157 and the second water outlet channel 156 to the water outlet 21 in sequence. The water-stop mechanism 17 includes a water-stop rod 172 and a water-stop seal 171. The water-stop rod 172 can be movably arranged in the first water outlet channel 155 and the second water outlet channel 156, or in other words, the water-stop rod 172 can move along the extension direction of the first water outlet channel 155 and the second water outlet channel 156, and the water-stop seal 171 is connected to the water-stop rod 172 and is constructed to be able to seal or open the water-stop connection 157 under the drive of the water-stop rod 172 to cut off or connect the first water outlet channel 155 and the second water outlet channel 156. That is to say, by driving the water-stop seal 171 to move through the water-stop rod 172, the water-stop seal 171 can seal the water-stop connection 157 to cut off the first water outlet channel 155 and the second water outlet channel 156, or the water-stop seal 171 can open the water-stop connection 157 to connect the first water outlet channel 155 and the second water outlet channel 156. A pressure relief channel 173 is provided inside the water stop rod 172, and the pressure relief channel 173 is connected to the first water outlet channel 155 and the second water outlet channel 156. The pressure relief mechanism 13 is arranged in the pressure relief channel 173, and the pressure relief mechanism 13 can open the pressure relief channel 173 to connect the first water outlet channel 155 and the second water outlet channel 156 to perform pressure relief work when the water pressure in the first water outlet channel 155 is greater than the preset water pressure, and seal the pressure relief channel 173 when the water pressure is less than the preset water pressure, so that the water stop mechanism 17 can stop water normally. In this way, even when the water pressure is greater than the preset water pressure, the water-stopping mechanism 17 can be activated to cut off the first water outlet channel 155 and the second water outlet channel 156. At this time, the pressure relief mechanism 13 will automatically open the pressure relief channel 173 to connect the first water outlet channel 155 and the second water outlet channel 156, thereby avoiding excessive water pressure in the shower head 100 and the water pipe 500, improving the safety of the shower water-stopping structure 10 and the shower head 100, and allowing the water-stopping mechanism 17 to achieve complete water-stopping without worrying about components bursting due to high water pressure. In addition, by arranging the pressure relief mechanism 13 in the water-stopping rod 172, the overall volume of the shower water-stopping structure 10 can be reduced, thereby improving the user's holding experience.

[0062] In summary:

[0063] The first embodiment of the present invention provides a shower water-stopping structure 10, which has the functions of completely stopping water and relieving pressure when the water pressure is high, and has the characteristics of high safety and small size.
