[0014] Further, the first partition plate and the second partition plate have the same structure and the cross-sectional shape is L-shaped. The first partition plate and the second partition plate both include a fixing portion close to the pipe body and a sealing portion far from the pipe body. The sealing portions on the first partition plate and the second partition plate are both located above the control plate.

[0015] Further, both ends of the control plate are closely connected to the inner wall of the pipe body. A first inclined portion is provided at the top of the control plate close to the sealing portion, and a second inclined portion adapted to the first inclined portion is provided at the bottom of the sealing portion.

[0016] Further, a fastening seat is fixed to the top end inside the pressing seat.

[0020] Advantages of the present invention:

[0021] In the present invention, when the pressing seat is pressed, the pressing seat presses the valve rod through the fastening seat, so that the control board at the bottom end of the valve rod leaves the sealing part, and the control makes the water inlet communicate with the water outlet. At this time, the valve is in the open state. Under the action of the delay spring, the pressing seat slowly moves upward until the control board abuts against the sealing part again, and the water inlet and the water outlet are closed and communicated. At this time, the valve is in the closed state; by setting the first inclined part and the second inclined part, during the continuous upward movement of the control board, the gap between the sealing part and the control board gradually becomes smaller, thereby adjusting the flow rate of the flushing water. When in use, the operator can apply different magnitudes of force to the pressing seat, thereby adjusting the downward movement distance of the control board, and thus controlling the flow rate of the flushing water, which has high practicability.

[0022] Through the arrangement of the first magnetic plate and the second magnetic plate, when the user presses the pressing seat with great force, the mutual attraction between the first magnetic plate and the second magnetic plate is utilized to counteract the reset action of the delay spring, slow down the time for the control board to move upward, thereby increasing the time for the control board to press downward, so that the valve remains open for a long time, and the flushing water can maintain a large flow rate, enabling the valve to have a multi-stage delay adjustment function, greatly improving the richness of the valve's use. The telescopic spring is provided to prevent the first magnetic plate and the second magnetic plate from being difficult to separate after long-term contact, causing the valve to remain open for a long time and resulting in waste of flushing water.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0032] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0033] A time-delay self-closing water-saving flushing valve includes a pipe body 1. A pipe cavity 101 is penetrated through the middle of the pipe body 1. One end of the pipe body 1 serves as the water inlet, and the other end of the pipe body 1 serves as the water outlet. A connecting seat 2 is fixed on the top of the pipe body 1. A pressing seat 3 is arranged outside the connecting seat 2. The bottom of the pressing seat 3 is provided with an opening. The pressing seat 3 is sleeved outside the connecting seat 2 and is adapted to the connecting seat 2. A valve stem 301 is arranged at the bottom of the pressing seat 3. The bottom end of the valve stem 301 passes through the connecting seat 2 and the pipe body 1 and is fixed with a control board 302. The valve stem 301 is slidably connected to the connecting seat 2. A first partition 303 and a second partition 304 are respectively arranged on both sides of the control board 302. The first partition 303 is fixed at the top of the inner side of the pipe body 1 near the water inlet, and the second partition 304 is fixed at the bottom of the inner side of the pipe body 1 near the water outlet. The first partition 303 and the second partition 304 respectively isolate both ends of the pipe body 1, and cooperate with the control board 302 to control the connection and closing of the water inlet and the water outlet.

[0034] A delay spring 307 is sleeved outside the valve stem 301. Both ends of the delay spring 307 are respectively connected to the connecting seat 2 and the pressing seat 3. The delay spring 307 can control the reset of the valve stem 301.

[0035] The shape of the pipe body 1 is cylindrical, and the shape of the pipe cavity 101 is square, which is convenient for better achieving sealing and playing a closing role.

[0036] A first connecting pipe 102 is sleeved on the outer surface of one end of the water inlet on the pipe body 1, and a second connecting pipe 103 is sleeved on the outer surface of one end of the water outlet on the pipe body 1. The first connecting pipe 102 and the second connecting pipe 103 are detachably installed at both ends of the pipe body 1, facilitating the connection to external water pipes through the first connecting pipe 102 and the second connecting pipe 103.

[0037] An opening is provided through the middle of the first connecting pipe 102 and the second connecting pipe 103. External threads are provided on the outer surfaces of both ends of the pipe body 1, and internal threads adapted to the external threads at both ends of the pipe body 1 are provided on the inner surfaces of the first connecting pipe 102 and the second connecting pipe 103. Moreover, internal threads are also provided on the sides of the inner surfaces of the first connecting pipe 102 and the second connecting pipe 103 away from the pipe body 1, and these internal threads are used for connecting external water pipes or nozzles.

[0038] The first partition plate 303 and the second partition plate 304 have the same structure and an L-shaped cross-section. Both the first partition plate 303 and the second partition plate 304 include a fixing portion 305 close to the pipe body 1 and a sealing portion 306 away from the pipe body 1. The sealing portions 306 on the first partition plate 303 and the second partition plate 304 are both located above the control plate 302.

[0039] Both ends of the control plate 302 are tightly connected to the inner wall of the pipe body 1. A first inclined portion is provided at the top of the control plate 302 close to the sealing portion 306, and a second inclined portion adapted to the first inclined portion is provided at the bottom of the sealing portion 306. By providing the first inclined portion and the second inclined portion, the gap between the sealing portion 306 and the control plate 302 gradually becomes smaller during the continuous upward movement of the control plate 302, thereby regulating the flow rate of the flushing water. When the control plate 302 comes into contact with the sealing portion 306, the water inlet and the water outlet are closed and connected, and the valve is in the closed state at this time.

[0040] A fastening seat 308 is fixed at the inner top of the pressing seat 3. A fastening groove is provided through the middle of the fastening seat 308, and internal threads are provided on the inner surface of the fastening groove. A threaded shaft 309 is fixed at the top of the valve stem 301, and the threaded shaft 309 is threadedly connected to the fastening groove, thus completing the connection between the pressing seat 3 and the valve stem 301.

[0041] A bolt groove is provided at the top of the threaded shaft 309, and a fixing bolt 310 is provided at the top of the pressing seat 3. The bottom end of the fixing bolt 310 passes through the pressing seat 3 and is located in the bolt groove. Through the setting of the fixing bolt 310, the connection between the threaded shaft 309 and the fastening seat 308 is made more stable, thereby making the connection between the valve stem 301 and the pressing seat 3 more stable and firm.

[0042] A sealing ring 201 is fixed to the top of the connecting seat 2. The sealing ring 201 is sleeved outside the valve stem 301. The sealing ring 201 is made of rubber and is used to seal the connection gap between the connecting seat 2 and the valve stem 301.

[0043] An adjusting seat 4 is fixed to the bottom of the pipe body 1. The top of the adjusting seat 4 is provided with an opening extending into the pipe body 1. A first magnetic plate 401 is fixed to the inner bottom end of the adjusting seat 4, and a second magnetic plate 402 is fixed to the bottom of the control plate 302. The first magnetic plate 401 is adapted to the second magnetic plate 402. By using the mutual attraction between the first magnetic plate 401 and the second magnetic plate 402, the time for the control plate 302 to move upward is slowed down, thereby increasing the time for the control plate 302 to press downward, so that the valve has a multi-stage delay adjustment function.

[0044] Two telescopic rods 403 are symmetrically fixed to both sides of the bottom of the control plate 302. A telescopic spring 404 is sleeved outside the telescopic rods 403, and the top end of the telescopic spring 404 is fixed to the control plate 302. The setting of the telescopic spring 404 can prevent the first magnetic plate 401 and the second magnetic plate 402 from being difficult to separate after long-term contact, which may cause the valve to be opened for a long time and result in waste of flushing water.

[0045] Working principle:

[0046] When the present invention is in use, when the pressing seat 3 is pressed, the pressing seat 3 presses the valve stem 301 through the fastening seat 308, so that the control plate 302 at the bottom end of the valve stem 301 leaves the sealing part 306, and the water inlet and the water outlet are made to communicate. At this time, the valve is in the open state. Under the action of the delay spring 307, the pressing seat 3 slowly moves upward until the control plate 302 abuts against the sealing part 306 again, and the water inlet and the water outlet are closed and communicated. At this time, the valve is in the closed state; by setting the first inclined part and the second inclined part, during the continuous upward movement of the control plate 302, the gap between the sealing part 306 and the control plate 302 gradually becomes smaller, so as to adjust the flow rate of the flushing water. When in use, the operator can apply different magnitudes of force to the pressing seat 3, thereby adjusting the downward movement distance of the control plate 302, so as to control the flow rate of the flushing water, which has high practicability.

[0047] Through the arrangement of the first magnetic plate 401 and the second magnetic plate 402, when the user presses the pressing seat 3 with great force, the mutual attraction between the first magnetic plate 401 and the second magnetic plate 402 is used to counteract the reset action of the delay spring 307, slow down the time for the control plate 302 to move upward, thereby increasing the time for the control plate 302 to press downward, so that the valve remains open for a long time, and the flushing water can maintain a relatively large flow rate, so that the valve has a multi-stage delay adjustment function.

[0048] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
