[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In order to solve the problem that the switch of the existing flush valve is integrated with the valve body, the switch must be installed where the valve body is installed, and the position of the switch is determined by the position of the valve body, which brings certain difficulties to the installation; please refer to Figure 1-4 , the utility model provides the following solutions:

[0020] An automatic water pressure flushing valve includes a valve body 1, a water outlet 101 is provided at one end of the valve body 1, and an air port sealing end 103 is provided at the other end of the valve body 1, wherein a water inlet 102 is provided above the valve body 1, an inner valve tube 2 is provided inside the valve body 1, and a valve core assembly 3 is provided inside the inner valve tube 2, wherein the air port sealing end 103 is closely connected with the inner valve tube 2 and the valve core assembly.

[0021] Furthermore, a water supply through hole 201 is provided on the outer surface of the inner valve tube 2 , which corresponds to the water inlet 102 . Sealing rings 202 are provided at both ends of the inner valve tube 2 , and the sealing rings 202 fit the valve body 1 .

[0022] Furthermore, the valve core assembly 3 is telescopically connected to the inner valve tube 2 , and the valve core assembly 3 includes an external pressure chamber 303 and an internal pressure chamber 304 , wherein the external pressure chamber 303 and the valve body 1 are interconnected, and an air hole is provided between the external pressure chamber 303 and the internal pressure chamber 304 .

[0023] Furthermore, a ball valve 301 is provided inside the external pressure chamber 303, and a resisting spring 3011 is provided at one end of the ball valve 301. The ball valve 301 is telescopically connected to the external pressure chamber 303 through the resisting spring 3011, and a contraction spring 302 is provided inside the internal pressure chamber 304. The valve core assembly 3 is telescopically connected to the air port sealing end 103 through the contraction spring 302. The ball valve 301 will be pressed against the air hole between the external pressure chamber 303 and the internal pressure chamber 304 under the action of the resisting spring 3011, and the valve core assembly 3 will be pressed against the air hole between the external pressure chamber 303 and the internal pressure chamber 304 after the air pressure is injected into the internal pressure chamber 304. When the air pump continues to increase the pressure, the ball valve 301 is pushed open. At this time, the internal pressure chamber 304 and the external pressure chamber 303 are connected. After the ball valve 301 is displaced, the gas is discharged and the contraction spring 302 resets the valve core assembly 3. At this time, the water at the water inlet 102 can enter the inner valve tube 2 through the water supply through hole 201. After the gas pressure in the internal pressure chamber 304 decreases, the retaining spring 3011 will again press the ball valve 301 against the air hole to complete the water cut-off operation.

[0024] Furthermore, an air valve interface 1031 is provided on the outside of the air port sealing end 103, and the air valve interface 1031 and the internal pressure chamber 304 are interconnected. The air valve interface 1031 can be connected to the air pump through a hose structure. At the same time, a single set of air pumps can be connected to multiple flushing valves through a tap, so that the switch does not need to be installed along with the flushing valve.

[0025] Working principle: the air valve interface 1031 can be connected to the air pump through a hose structure. At the same time, a single group of air pumps can be connected to multiple flushing valves through a tap. The ball valve 301 will be pressed against the air hole between the external pressure chamber 303 and the internal pressure chamber 304 under the action of the resisting spring 3011, and the valve core assembly 3 will be pushed out after the air pressure is injected into the internal pressure chamber 304. In this state, the valve core assembly 3 will block the water supply through hole 201 to realize the closing operation of the flushing valve. When the air pump continues to increase the pressure, the ball valve 301 is pushed open. At this time, the internal pressure chamber 304 and the external pressure chamber 303 are together, and the gas is discharged after the ball valve 301 is shifted. The contraction spring 302 resets the valve core assembly 3. At this time, the water at the water inlet 102 can enter the inner valve tube 2 through the water supply through hole 201. After the internal gas pressure of the internal pressure chamber 304 becomes smaller, the resisting spring 301 will again press the ball valve 301 against the air hole to complete the water cut-off operation.
