[0029] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] As shown in the figure, a micro-water toilet flushing device of the present utility model, the device includes:

[0032] Flushing system, water inlet system and water storage tank. The flushing system and the water inlet system are arranged inside the water storage tank. The water inlet system includes a floating body, a floating body limiting sleeve, a lever system and a water inlet opening and closing device; the flushing system includes a pressing handle 1, a water pressure piston 9, a moving lever 2, a spring 3, a suction pipe and a flushing pipe; the water storage tank can be set as a cube or a cylinder according to needs, and an air outlet is arranged at the upper part of the water storage tank.

[0033] The water inlet system includes: a floating body 10 and a lever system; the floating body is of a hollow structure and can move up and down inside the floating body limiting sleeve; a conical groove structure is arranged at the center of the upper end of the floating body. As shown in the figure, the groove structure is preferably an inverted cone.

[0034] The lever system in the water inlet system is composed of four parts, namely a water inlet connecting rod 24, a floating body connecting rod 13, a cross bar (lever) 25 and a support rod 17. The two connecting rods 24, 13 and the cross bar are connected by a rotating shaft. The support rod is installed inside the water storage tank and is fixed, and the cross bar is hinged on the support rod, and only allows the cross bar to rotate in the same plane at the connection. Since the two connecting rods 24, 13 and the cross bar are connected by a rotating shaft, under the action of gravity, the two connecting rods 24, 13 are always vertically downward;

[0035] A water outlet valve 14 is arranged at the water outlet of the water inlet pipe 22, a sealing cover plate is arranged on the valve port inside the water outlet valve, and the sealing cover plate is arranged below the water inlet connecting rod; when the water level in the water storage tank rises, the floating body presses against the floating body connecting rod under the action of water to drive the lever to drive the water inlet connecting rod to press down the sealing cover plate to block the valve port, and the water in the water inlet pipe cannot enter the water storage tank; when the water level in the water storage tank drops, the floating body sinks, and the force pressing against the sealing cover plate on the lever is lost, and the water in the water inlet pipe enters the water storage tank under the action of water pressure; the water replenishment is completed.

[0036] In order to prevent the floating body from tilting and other reasons and being unable to float normally after sinking to the bottom of the water storage tank when there is no water in the water storage tank, a soft connecting rope 12 is tied between the lever and the floating body. The length of the soft connecting rope 12 is based on that the floating body does not sink to the bottom when there is no water in the water storage tank. In order to ensure that the groove structure can correctly abut against the right vertical rod, the gap distance between the floating body shell and the inner wall of the floating body limiting sleeve shall not be greater than the radius of the groove.

[0037] The sealing cover plate should be able to seal the valve port, and its shape can be designed as square or circular according to needs; for example, the form of the sealing cover plate can be selected according to needs. For example, the sealing cover plate can be in the shape of a cap or an inverted cone to better seal the valve port.

[0038] The pressing handle 1 and the piston 9 of the flushing system are integrally designed. A sliding groove is designed at the bottom of the piston, which is composed of a rolling pulley 8 arranged at the end of the lever 2. The rolling pulley can move freely along the sliding groove. A spring 3 is connected at the center position of the lever, and the other end of the lever is fixed on the wall of the flushing tank 26;

[0039] A water-absorbing porous filter plate 5 is provided at the center of the bottom plate of the flushing water tank. A one-way valve 4 is provided under the porous filter plate. The structural form of the one-way valve can be selected according to needs. For example, a check ball is adopted, and a water suction pipe 18 is connected under the check ball; the flushing pipe is in an inverted "L" shape, and a one-way valve 6 is provided at the water inlet end of the flushing pipe. For example, a flushing check ball, a flushing porous filter plate 7 is provided above the flushing check ball, and the water outlet end of the flushing pipe is connected to the toilet.

[0040] The shape of the storage tank of the micro-water toilet flushing device can be designed into a square column shape or a cylindrical shape. When the device is applied to areas without pressurized water, the air outlet provided at the upper part of the storage tank can also be used as a water injection port. When used as a water injection port, the pipe diameter should be enlarged, and anti-insect and anti-ant measures should be provided at the air outlet.

[0041] When flushing is required, when the pressing handle 1 is pressed, the piston 9 moves downward synchronously, the rolling pulley 8 moves reversely along the sliding groove 19, the moving lever presses down the spring 3, and at the same time, the water in the flushing water tank 26 is squeezed by the piston 9, and the water pressure pushes open the flushing check ball 6. The water passes through the flushing porous filter plate 7, and the clear water enters the toilet along the flushing pipe from the top of the storage tank 20. When the flushing process is completed, the pressing handle 1, the piston 9 and the moving lever 2 return to their original positions under the drive of the spring 3. The suction force brought about causes the water in the storage tank 20 to surge upward along the water suction pipe 18 to push open the water absorption check valve 4 and enter the flushing water tank 26, thus completing a flushing cycle. After several flushing cycles are completed, the water level in the storage tank 20 drops, the floating body 10 in the water inlet system drops along the floating body limiting sleeve 11, the floating body 10 straightens the soft connecting rope 12, and the soft connecting rope 12 pulls the vertical rod I 13 to drop, thereby driving the entire lever system to act. The vertical rod II 24 drives the cover plate 14-d to rise, and the socket head 14-a moves out of the socket 14-c, and tap water enters the storage tank 20 from the water inlet pipe 22. When the water level rises, the floating body 10 rises. When it touches the vertical rod I 13, it drives the lever system, and the vertical rod II 24 drives the cover plate 14-d to drop, and the socket head 14-a is inserted into the socket 14-c, and the water inlet is closed. At this time, the water replenishment is completed and the water inlet stops.
