Description

[0001] The invention belongs to the technical field of bathroom shower heads, and in particular relates to a switch button shower head. Background Art

[0002] Bathroom showers are commonly used shower equipment in bathrooms. There are many types. Handheld showers can be held in the hand and moved freely, and are flexible to use. Some handheld showers have switch buttons, which means that the water flow can be turned on and off through the button on the handle.

[0003] After water flows through the existing switch button shower, a greater pressing force is required to reset it. There is usually a spring or similar elastic component inside the shower to adjust and reset the water pressure. When water flows through the inside, the pressure is relatively high, and the spring and other elastic components are stretched or compressed to a large deformation degree, storing a large elastic potential energy. In this case, to reset the shower, it is necessary to overcome the large elastic potential energy stored in the spring, so a greater pressing force is required to restore the spring and other elastic components to their initial state. At the same time, when the internal water pressure is relatively high, the speed and pressure of water flowing inside the shower increase, which will generate a large reaction force on the adjustment component inside the shower. This reaction force will hinder the reset of the adjustment component, so that a greater external force needs to be applied to overcome the reaction force of water during reset, which is manifested as requiring a greater pressing force to reset the button. When people use it for bathing, because the surface of the shower is smooth and the hands of people are wet, there is a risk of the shower slipping when pressing the button with greater force;

[0004] Based on the above mentioned situation, we found that it is difficult to avoid the above problems with the switch button shower head in the prior art. Therefore, we proposed a switch button shower head which is not affected by water pressure, and is engaged with the button and the inclined structure, and the slope bramble is reset so that the pressing adjustment force is not affected. Summary of the invention

[0005] The purpose of the present invention is to target the existing switch button shower head, which has the advantage of not being affected by water pressure, and the button and the inclined structure are engaged, and the reset of the sloped bramble is coordinated so that the pressing adjustment force is not affected.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a switch button shower head, comprising a gripping part and a spraying part, the spraying part is installed on the inner side of the left side of the gripping part, a water inlet is installed on the inner side of the gripping part, a switching water channel is installed on the bottom of the inner side of the gripping part, the right side of the switching water channel is connected to the water inlet, a water outlet channel is installed on the left side of the inner side of the gripping part, and a button structure A and a button structure B are provided on the inner side of the gripping part;

[0007] The key structure A comprises a pressing part A, a key skeleton A is installed on the inner side of the pressing part A, a rotating shaft A is installed on the inner side of the key skeleton A, a skeleton base A is movably connected to the outer side of the key skeleton A, a support cover A is movably connected to the inner side of the holding part, and the support cover A is arranged at the bottom of the skeleton base A, a movable rod A is installed on the inner side of the rotating shaft A, and the outer side of the movable rod A is movably connected to the support cover A, a piston A is installed on the inner side of the holding part, a bottom spring A is installed on the top of the inner side of the piston A, and the top of the bottom spring A contacts the bottom of the support cover A, an inner spring A is provided on the outer side of the bottom of the movable rod A, and the top of the inner spring A contacts the inner side of the support cover A, a top spring A is installed on the bottom of the rotating shaft A, and the bottom of the top spring A contacts the support cover A, and the bottom of the piston A contacts the switching water channel;

[0008] The button structure B includes a pressing part B, a button skeleton B is installed on the inner side of the pressing part B, a rotating shaft B is clamped on the inner side of the button skeleton B, a movable rod B is movably connected to the inner side of the rotating shaft B, a skeleton base B is provided on the outer side of the button skeleton B, a support cover B is clamped on the inner side of the holding part, the support cover B and the skeleton base B are movably connected, the inner side of the support cover B and the movable rod B are movably connected, an inner spring B is provided at the bottom of the inner side of the support cover B, a deformable washer B is sleeved on the bottom of the support cover B, a washer skeleton B is clamped on the inner side of the deformable washer B, a bottom spring B is installed on the top of the washer skeleton B, the top of the bottom spring B is in contact with the bottom of the support cover B, the deformable washer B and the washer skeleton B are in contact with the inner side of the switching water channel, a top spring B is provided on the top of the support cover B, and the top of the top spring B is in contact with the rotating shaft B.

[0009] By adopting the above technical solution, when the key structure A is used to open and close the water supply, the pressing part A is pressed, and the key frame A connected thereto will also move vertically downward, and then the slope ribs on the key frame A will rotate downward against the slope ribs on the rotating shaft A, bringing the movable rod A down vertically as well. When the slope ribs on the key frame A rotate downward against the slope ribs on the rotating shaft A to a certain position, when the slope ribs of the rotating shaft A just rotate to the slope rib position of the frame base A, they will slide onto the slope rib step of the frame base A and get stuck, so as to complete the positioning of the vertical downward movement. When water flow needs to be supplied, the pressing part is pressed again, and the slope ribs on the key frame A will rotate downward against the slope ribs on the rotating shaft A. When it reaches a certain position, the step of the slope rib of the frame base A is disengaged, and the shaft A is pushed by the key frame A through the slope rib to rotate into the empty groove of the frame base A. After letting go, the key frame A, the shaft A and the movable rod A connected thereto will retract to their original positions along the empty groove of the frame base A, completing the reset. When the key is turned on, water passes through the water inlet and the switching water channel to the position of the piston A. The main water flow passes through the inclined surface of the tower-shaped gasket A at the bottom of the piston A. A part of the water passes through the water inlet hole next to the piston A and enters the cavity of the piston A, and then flows out from the water outlet hole in the middle of the piston A. In this way, the piston is always in a depressurized state. At this time, under the impact of the water pressure, the entire piston A will be rushed upward, so that the inclined surface of the tower-shaped gasket A and the end face of the mouth of the water channel A are opened, and the water will flow along the water outlet channel The water flows out to supply water, and the pressing part is pressed again. The key skeleton A will move the rotating shaft A downward, thereby driving the movable rod A on the rotating shaft A to move vertically. The head plane of the movable rod A blocks the water outlet hole in the piston A, and water passes through the water inlet hole next to the piston A and enters the cavity of the piston A. Since the water outlet hole in the middle of the piston A is blocked at this time, as the water continues to flow into the cavity of the piston A, the cavity of the piston A is always in a pressure-maintaining state. Under the action of water pressure, the tower-shaped gasket A at the lower end of the piston A will always maintain a seal with the switching water channel, so that the piston A cannot move upward, so the water cannot continue to be supplied and flow out, completing the water-stopping state. When the key structure B is used to open and close the water supply, press the pressing part B to press the key skeleton B and move downward vertically, and then press The slope ribs on the key frame B will press the slope ribs on the rotating shaft B to rotate downward, and the movable rod B connected thereto will also move downward. When the slope ribs on the key frame B rotate downward to a certain position against the slope ribs on the rotating shaft B, when the slope ribs of the rotating shaft B just rotate to the slope rib position of the frame base B, it will slide onto the step of the slope ribs of the frame base B and get stuck, completing the positioning of the downward movement. When it is necessary to switch the key state, press the pressing part B again, and the slope ribs on the key frame B will rotate downward to a certain position against the slope ribs on the rotating shaft B, disengage from the slope rib steps of the key frame base B, and the rotating shaft B is pushed by the key frame B through the slope ribs and rotated into the empty groove of the frame base B.After letting go, the key frame B, the rotating shaft B and the movable rod B will retract to their original positions along the empty groove of the key frame base B to complete the reset. When the key structure B is open, water is supplied to the water inlet channel and enters the switching water channel, and then passes through the deformed gasket B. The main water flow passes through the lower end face of the deformed gasket B, and a part of the water passes through the water inlet hole next to the deformed gasket B component, enters the cavity of the deformed gasket B component, and then flows out from the water outlet hole in the middle of the deformed gasket B component. At this time, the deformed gasket B component has been in a pressure relief state. Under the action of water pressure, the deformed gasket B will deform upward under the impact of water pressure, thereby making the end face of the deformed gasket B and the water outlet channel collide. In the water-stopping state, the pressing part is pressed, and the key frame B will move the shaft B downward, thereby driving the movable rod B on the shaft B to move vertically downward. The plug plane of the head of the movable rod B blocks the water outlet in the middle of the deformed gasket B. Water passes through the water inlet next to the deformed gasket B and enters the cavity of the deformed gasket B. Since the water outlet in the middle of the deformed gasket B is blocked at this time, as water continues to flow into the cavity of the deformed gasket B, the cavity of the deformed gasket B is always in a pressure-maintaining state. Under the action of water pressure, the inclined part of the lower end of the deformed gasket B will always be sealed with the water outlet flow channel, so that the deformed gasket B cannot move upward, thereby completing the water-stopping state.

[0028] In summary, the present invention has the following beneficial effects:

[0029] When the key structure A is used to open and close the water supply, the pressing part A is pressed, and the key frame A connected thereto will also move vertically downward, and then the slope ribs on the key frame A will rotate downward against the slope ribs on the rotating shaft A, bringing the movable rod A down vertically as well. When the slope ribs on the key frame A push against the slope ribs on the rotating shaft A and rotate downward to a certain position, when the slope ribs of the rotating shaft A just rotate to the slope rib position of the frame base A, they will slide onto the slope rib step of the frame base A and get stuck, so as to complete the positioning of the vertical downward movement. When water flow needs to be supplied, the pressing part is pressed again, and the slope ribs on the key frame A will rotate downward against the slope ribs on the rotating shaft A to a certain position. Disengage the steps of the slope ribs of the frame base A, and the shaft A is pushed by the key frame A through the slope ribs to rotate into the empty groove of the frame base A. After letting go, the key frame A, the shaft A and the movable rod A connected thereto will retract to their original positions along the empty groove of the frame base A, completing the reset. When the key is turned on, water passes through the water inlet and the switching water channel to the position of the piston A. The main water flow passes through the inclined surface of the tower-shaped gasket A at the bottom of the piston A, and a part of the water passes through the water inlet hole next to the piston A and enters the cavity of the piston A, and then flows out from the water outlet hole in the middle of the piston A. In this way, the piston is always in a depressurized state. At this time, under the impact of the water pressure, the entire piston A will be pushed upward, so that the inclined surface of the tower-shaped gasket A and the end face of the mouth of the water channel A are opened, and the water will flow out along the water outlet channel for supply Water, press the pressing part again, the key skeleton A will make the rotating shaft A move downward, thereby driving the movable rod A on the rotating shaft A to move vertically, and the head plane of the movable rod A blocks the water outlet hole in the piston A, and the water passes through the water inlet hole next to the piston A and enters the cavity of the piston A. Since the water outlet in the middle of the piston A is blocked at this time, as the water continues to flow into the cavity of the piston A, the cavity of the piston A is always in a pressure-maintaining state. Under the action of water pressure, the tower-shaped gasket A at the lower end of the piston A will always maintain a seal with the switching water channel, so that the piston A cannot move upward, so the water cannot continue to be supplied and flow out, completing the water-stopping state. When the key structure B is used to open and close the water supply, press the pressing part B to press the key skeleton B, move downward vertically, and then press the key skeleton B. The slope ribs on the frame B will press the slope ribs on the rotating shaft B to rotate downward, and the movable rod B connected thereto will also move downward. When the slope ribs on the key frame B push the slope ribs on the rotating shaft B to rotate downward to a certain position, when the slope ribs of the rotating shaft B just rotate to the slope rib position of the frame base B, it will slide onto the step of the slope ribs of the frame base B and get stuck, completing the positioning of the downward movement. When the key state needs to be switched, the pressing part B is pressed again, and the slope ribs on the key frame B will push the slope ribs on the rotating shaft B to rotate downward to a certain position, disengage from the slope rib steps of the key frame base B, and the rotating shaft B is pushed by the key frame B through the slope ribs to rotate into the empty groove of the frame base B.After letting go, the key frame B, the rotating shaft B and the movable rod B will retract to their original positions along the empty groove of the key frame base B to complete the reset. When the key structure B is open, water is supplied to the water inlet channel and enters the switching water channel, and then passes through the deformed gasket B. The main water flow passes through the lower end face of the deformed gasket B, and a part of the water passes through the water inlet hole next to the deformed gasket B, enters the cavity of the deformed gasket B, and then flows out from the water outlet hole in the middle of the deformed gasket B. At this time, the deformed gasket B is always in a pressure relief state. Under the action of water pressure, the deformed gasket B will deform upward under the impact of water pressure, so that the end face of the deformed gasket B and the water outlet channel are in a water-stopping state. Under the pressure, the pressing part is pressed, and the key frame B will move the shaft B downward, thereby driving the movable rod B on the shaft B to move vertically downward. The plug plane of the head of the movable rod B blocks the water outlet in the middle of the deformed gasket B. Water passes through the water inlet next to the deformed gasket B and enters the cavity of the deformed gasket B. Since the water outlet in the middle of the deformed gasket B is blocked at this time, as the water continues to flow into the cavity of the deformed gasket B component, the cavity of the deformed gasket B is always in a pressure-maintaining state. Under the action of water pressure, the inclined part of the lower end of the deformed gasket B will always be sealed with the water outlet flow channel, so that the deformed gasket B cannot move upward, thereby completing the water-stopping state.

[0040] The key structure A6 includes a pressing part A601, a key frame A602 is installed on the inner side of the pressing part A601, a rotating shaft A603 is installed on the inner side of the key frame A602, a frame base A604 is movably connected to the outer side of the key frame A602, a support cover A605 is movably connected to the inner side of the holding part 1, and the support cover A605 is arranged at the bottom of the frame base A604, a movable rod A606 is installed on the inner side of the rotating shaft A603, and the outer side of the movable rod A606 is movably connected to the support cover A605. A piston A607 is installed on the inner side of the holding part 1, a bottom spring A608 is installed on the top of the inner side of the piston A607, the top of the bottom spring A608 contacts the bottom of the support cover A605, an inner spring A609 is provided on the outer side of the bottom of the movable rod A606, the top of the inner spring A609 contacts the inner side of the support cover A605, a top spring A610 is installed on the bottom of the rotating shaft A603, the bottom of the top spring A610 contacts the support cover A605, and the bottom of the piston A607 contacts the switching water channel 4;

[0041] When the key structure A6 is used to open and close the water supply, the pressing part A601 is pressed, and the key frame A602 connected thereto will also move vertically downward, and then the slope ribs on the key frame A602 will rotate downward against the slope ribs on the rotating shaft A603, and the movable rod A606 will also descend vertically. When the slope ribs on the key frame A602 rotate downward against the slope ribs on the rotating shaft A603 to a certain position, when the slope ribs of the rotating shaft A603 just rotate to the slope rib position of the frame base A604, it will slide onto the slope rib step of the frame base A604 and get stuck. , to complete the positioning of vertical downward movement. When water flow needs to be supplied, the pressing part is pressed again, and the slope ribs on the key frame A602 will push the slope ribs on the rotating shaft A603 to rotate downward to a certain position, disengaging the steps of the slope ribs of the frame base A604, and the rotating shaft A603 is pushed by the key frame A602 through the slope ribs to rotate into the empty groove of the frame base A604. After letting go, the key frame A602 and the rotating shaft A603 and the movable rod A606 connected thereto will retract to their original positions along the empty groove of the frame base A604, completing the reset. The key is in the open state, and water flows into the key frame. Water channel 3 and switching water channel 4 are connected to the position of piston A607. The main water flows through the inclined surface of the tower-shaped gasket A at the bottom of piston A607. A part of the water passes through the water inlet hole next to piston A607 and enters the cavity of piston A607, and then flows out from the water outlet hole in the middle of piston A607. In this way, piston A607 is always in a pressure relief state. At this time, under the impact of water pressure, the entire piston A607 will be rushed upward, so that the inclined surface of the tower-shaped gasket A and the end face of the mouth of water channel A are opened, and water will flow out along the water outlet channel 5 to supply water. The pressing part is pressed again, and the key skeleton A602 will move the rotating shaft A603 downward, from The movable rod A606 on the rotating shaft A603 is driven to move vertically, and the head plane of the movable rod A606 blocks the water outlet hole in the piston A607. Water enters the cavity of the piston A607 through the water inlet hole next to the piston A607. Since the water outlet in the middle of the piston A607 is blocked at this time, as the water continues to flow into the cavity of the piston A607, the cavity of the piston A607 is always in a pressure-maintaining state. Under the action of water pressure, the tower-shaped gasket A at the lower end of the piston A607 will always remain sealed with the switching water channel 4, making it impossible for the piston A607 to move upward. Therefore, water cannot continue to be supplied and flow out, completing the water-stopping state.

[0042] like Figure 2 As shown, the inner side of the rotating shaft A603 is movably connected with a clamping ring A8, and the inner side of the clamping ring A8 is movably connected to the movable rod A606. By providing the clamping ring A8, the sealing performance of the structure can be improved while connecting the structure.

[0043] like Figure 2As shown, a protrusion is provided at the bottom of the movable rod A606, and the top of the protrusion contacts the bottom of the inner spring A609. The outer side of the movable rod A606 fits the shape of the clamping ring A8. The protrusion is provided to press against the bottom structure, and at the same time, the inner spring A609 can be prevented from falling off from the bottom of the structure.

[0044] like Figure 3 As shown, a fixing ring A9 is sleeved on the inner side of the support cover A605, and the fixing ring A9 is arranged on the outer side of the movable rod A606. A sealing member is arranged at the bottom of the fixing ring A9. The fixing ring A9 is used to fix the movable rod A606, and at the same time, it can cooperate with the sealing member to improve the sealing of the structure, and can also play a leak-proof effect when the structure is pressed.

[0045] like Figure 3 As shown, the outer side of the piston A607 is provided with an oil seal A10, the inner side of the piston A607 is installed with a rubber plug A11, and the outer side of the piston A607 is provided with a tower-shaped gasket A12. By providing the oil seal A10, the sealing performance of the structure can be improved. The rubber plug A11 cooperates with the tower-shaped gasket to enable the inclined surface to press against the water flow position for blocking.

[0046] like Figure 2 As shown, a sealing ring 16 is provided on the outer side of the water inlet 3, and the outer side of the sealing ring 16 is in close contact with the holding part 1. By providing the sealing ring 16, the sealing between the water inlet 3 and the holding part 1 can be easily improved, and the connection can be made more stable.

[0047] like Figure 3 As shown, the holding portion 1 includes an upper clamping portion 101 and a lower clamping portion 102, and the inner sides of the upper clamping portion 101 and the lower clamping portion 102 are clamped with the water inlet 3 and the switching water channel 4. By arranging the upper clamping portion 101 and the lower clamping portion 102 to cooperate with each other, the internal structure can be easily installed or adjusted during assembly or maintenance.

[0048] Brief description of the use process: When the button is turned on, water flows through the water inlet channel 3 and the switching water channel 4 to the position of the piston A607. The main water flows through the inclined surface of the tower-shaped gasket A at the bottom of the piston A607. A part of the water passes through the water inlet hole next to the piston A607 and enters the cavity of the piston A607, and then flows out from the water outlet hole in the middle of the piston A607. In this way, the piston A607 is always in a pressure relief state. At this time, under the impact of water pressure, the entire piston A607 will be rushed upward, so that the inclined surface of the tower-shaped gasket A and the end face of the mouth of the water channel A are opened, and the water will flow out along the water outlet channel 5 to supply water. The pressing part is pressed again, and the key frame A602 will make the shaft A603 moves downward, thereby driving the movable rod A606 on the rotating shaft A603 to move vertically. The head plane of the movable rod A606 blocks the water outlet hole in the piston A607, and water enters the cavity of the piston A607 through the water inlet hole next to the piston A607. Since the water outlet in the middle of the piston A607 is blocked at this time, as the water continues to flow into the cavity of the piston A607, the cavity of the piston A607 is always in a pressure-maintaining state. Under the action of water pressure, the tower-shaped gasket A at the lower end of the piston A607 will always remain sealed with the switching water channel 4, making it impossible for the piston A607 to move upward. Therefore, water cannot continue to be supplied and flow out, completing the water-stopping state.

[0051] The key structure B7 includes a pressing portion B701, a key frame B702 is installed on the inner side of the pressing portion B701, a rotating shaft B703 is clamped on the inner side of the key frame B702, and a movable rod B704 is movably connected to the inner side of the rotating shaft B703, a frame base B705 is provided on the outer side of the key frame B702, a support cover B706 is clamped on the inner side of the holding portion 1, the support cover B706 is movably connected to the frame base B705, the inner side of the support cover B706 is movably connected to the movable rod B704, and the inner side of the support cover B706 is movably connected to the movable rod B704. An inner spring B707 is provided at the bottom of the side, a deformable washer B708 ​​is sleeved at the bottom of the support cover B706, a washer frame B709 is clamped on the inner side of the deformable washer B708, a bottom spring B710 is installed on the top of the washer frame B709, the top of the bottom spring B710 contacts the bottom of the support cover B706, the deformable washer B708 ​​and the washer frame B709 contact the inner side of the switching water channel 4, a top spring B711 is provided on the top of the support cover B706, and the top of the top spring B711 contacts the rotating shaft B703;

[0052] When the key structure B7 is used to open and close the water supply, the pressing part B701 is pressed to press the key frame B702 and move vertically downward, and then the slope ribs on the key frame B702 will press the slope ribs on the rotating shaft B703 to rotate downward, and the movable rod B704 connected thereto also moves downward. When the slope ribs on the key frame B702 rotate downward to a certain position against the slope ribs on the rotating shaft B703, when the slope ribs of the rotating shaft B703 just rotate to the slope rib position of the frame base B705, they will slide onto the step of the slope ribs of the frame base B705 and get stuck, completing the downward movement. Movement positioning, when it is necessary to switch the button state, press the pressing part B701 again, the slope ribs on the button skeleton B702 will push the slope ribs on the rotating shaft B703 to rotate downward to a certain position, disengage the slope rib steps of the button skeleton base B705, and the rotating shaft B703 is pushed by the button skeleton B702 through the slope ribs to rotate into the empty groove of the skeleton base B705. After letting go, the button skeleton B702, the rotating shaft B703 and the movable rod B704 will retract to their original positions along the empty groove of the button skeleton base B705 to complete the reset. When the button structure B7 is opened, water is supplied to the water inlet 3. , and enters the switching water channel 4, and then passes through the deformed gasket B708. The main water flow passes through the lower end surface of the deformed gasket B708, and a part of the water passes through the water inlet hole next to the deformed gasket B708, enters the deformed gasket B708 ​​cavity, and then flows out from the middle water outlet hole of the deformed gasket B708. At this time, the deformed gasket B708 ​​has been in a pressure relief state. Under the action of the water pressure, the deformed gasket B708 ​​will deform upward under the impact of the water pressure, so that the end surface of the deformed gasket B708 ​​and the water outlet channel 5, in the water-stopping state, press against the pressing part, and the key skeleton B702 will cause the rotating shaft B703 to move downward, thereby driving the rotating shaft B703 to move downward. The movable rod B704 on the shaft B703 moves vertically downward, and the plug 14 at the head of the movable rod B704 blocks the water outlet in the middle of the deformed gasket B708. Water passes through the water inlet next to the deformed gasket B708 ​​and enters the cavity of the deformed gasket B708. Since the water outlet in the middle of the deformed gasket B708 ​​is blocked at this time, as water continues to flow into the cavity of the deformed gasket B708, the cavity of the deformed gasket B708 ​​is always in a pressure-maintaining state. Under the action of water pressure, the inclined part of the lower end of the deformed gasket B708 ​​will always be sealed with the water outlet channel 5, so that the deformed gasket B708 ​​cannot move upward, thereby completing the water-stopping state.

[0053] like Figure 6 As shown, a clamping ring B13 is installed on the inner side of the rotating shaft B703, and the inner side of the clamping ring B13 is clamped with the outer side of the movable rod B704. The clamping ring B13 is arranged to cooperate with the movable rod B704 to improve the sealing between the structures.

[0054] like Figure 5As shown, a protrusion is provided at the bottom of the movable rod B704, and a plug 14 is installed at the bottom of the protrusion. The top of the protrusion contacts the bottom of the inner spring B707. The bottom position of the inner spring B707 is firmly placed by setting the protrusion. The plug 14 is used to play a stabilizing blocking effect when the structure blocks the bottom opening.

[0055] like Figure 5 As shown, a fixing ring B15 is clamped on the inner side of the support cover B706, and the inner side of the fixing ring B15 is in contact with the outer side of the movable rod B704. A sealing member is provided at the bottom of the fixing ring B15. The fixing ring B15 is provided to improve the connection and sealing of the structure, and the provided sealing member is used to press the bottom structure.

[0056] A brief description of the usage process: When the button structure B7 is open, water is supplied to the water inlet channel 3 and enters the switching water channel 4, and then passes through the deformed gasket B708. The main water flow passes through the lower end surface of the deformed gasket B708, and a part of the water passes through the water inlet hole next to the deformed gasket B708, enters the cavity of the deformed gasket B708, and then flows out from the water outlet hole in the middle of the deformed gasket B708. At this time, the deformed gasket B708 ​​is always in a pressure relief state. Under the action of water pressure, the deformed gasket B708 ​​will deform upward under the impact of water pressure, so that the end surface of the deformed gasket B708 ​​and the water outlet channel 5, in the water-stopping state, press against the pressing part, and the button skeleton B702 will make the rotating shaft B703 moves downward, thereby driving the movable rod B704 on the rotating shaft B703 to move vertically downward. The plane of the plug 14 at the head of the movable rod B704 blocks the water outlet in the middle of the deformed gasket B708, and water enters the cavity of the deformed gasket B708 ​​through the water inlet next to the deformed gasket B708. Since the water outlet in the middle of the deformed gasket B708 ​​is blocked at this time, as water continues to flow into the cavity of the deformed gasket B708, the cavity of the deformed gasket B708 ​​is always in a pressure-maintaining state. Under the action of water pressure, the inclined part of the lower end of the deformed gasket B708 ​​will always be sealed with the water outlet channel 5, so that the deformed gasket B708 ​​cannot move upward, thereby completing the water-stopping state.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
