The water filtering and inlet device is composed of an upper filter plate, a second connecting metal wire, a sealing plate, and a weight block. A fixing block is provided inside the upper filter plate. The second connecting metal wire is tightly wound around the fixing block and connected to the upper filter plate.

Since the clean water tank 22 is arranged above the circulating water tank 23, when flushing, the circulating water is flushed first, and the clean water is flushed later, so as to prevent the odor easily generated by flushing with circulating water;

[0012] After flushing, due to the gravity of the weight block 4203, the upper filter plate 4200 returns to its initial position, and at the same time pulls up the sealing plate 4202 to prevent the odor of the circulating water in the water storage chamber 421 from leaking. Through the cooperation between the internal components of the defecation recycling device, the purpose of flushing with circulating water, saving water resources, and effectively preventing the odor of circulating water from leaking is achieved.

[0023] The water pump described in the present invention, also called a water pump, is a machine for conveying liquid or pressurizing liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to convey liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0024] It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into positive displacement water pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their studio to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps.

[0025] The fixed pulley described in the present invention is a pulley. In mechanics, a typical pulley is a circular wheel that can rotate around a central axis. There are grooves on the circumferential surface of the circular wheel. The rope is wrapped around the grooves. If one end of the rope is pulled with force, the friction between the rope and the circular wheel will cause the circular wheel to rotate around the central axis. The pulley is actually a deformable, rotatable lever. The main functions of the pulley are to pull loads, change the direction of force, transmit power, etc. A machine composed of multiple pulleys is called a "pulley block" or "compound pulley". The mechanical advantage of the pulley block is large and can pull heavier loads. The pulley can also become a component of a chain drive or a belt drive to transmit power from one rotating shaft to another.

[0026] According to whether the position of the center axis of the pulley is movable, the pulley can be divided into "fixed pulley" and "movable pulley"; the center axis of the fixed pulley is fixed, and the center axis of the movable pulley can be moved, each has its own advantages and disadvantages. The fixed pulley and the movable pulley can be assembled together to form a pulley block, which not only saves effort but also can change the direction of force.

[0027] The circulating water mentioned in the present invention refers to the water obtained after the excrement is washed with water and then filtered.

[0028] When using it, first check whether all parts are stably connected. After confirming that all parts of the equipment are complete and in good appearance, connect the power supply. When flushing excrement, flush downward along the excretion pipe 30. When it reaches the water filter inlet device 420, it is impacted by the excretion water flow and the upper filter plate 4200 is flushed downward and pressed against the lower excretion pipe 30. The upper filter plate 4200 is connected to the sealing plate 4202 through the second connecting metal wire 4201 and falls under the impact of the water flow. Then, the filtered excretion water flow forms circulating water and enters the water storage chamber 421, and the filtered excretion residue flows out along the excretion discharge pipe 41. The circulating water entering the water storage chamber 421 is stored here. When the water storage chamber 421 is full, the buoyancy device 425 floats up , since the buoyancy rod 4251 is connected to the switch dial 4230 of the pumping motor 423 through the third connecting metal wire 4253, the buoyancy rod 4251 pulls the third connecting metal wire 4253 when floating up, the switch dial 4230 is pulled up, the pumping motor 423 is started, and the circulating water is pumped to the circulating water tank 23 through the pumping pipe 424 for standby use. When flushing is required, the switch 21 knob is rotated, and the first connecting metal wire 20 pulls up the clean water water-stopping rubber ring 212 and the circulating water water-stopping rubber ring 213 at the same time, so that the water flows down to flush the toilet. Since the clean water tank 22 is arranged above the circulating water tank 23, when flushing, the circulating water is flushed first, and the clean water is flushed later, so as to prevent the odor easily generated by flushing with circulating water;

[0029] After flushing, due to the gravity of the weight block 4203, the upper filter plate 4200 returns to its initial position, and at the same time pulls up the sealing plate 4202 to prevent the odor of the circulating water in the water storage chamber 421 from leaking. The internal components of the defecation recycling device cooperate with each other to achieve the purpose of flushing with circulating water, saving water resources, and effectively preventing the leakage of odor of circulating water. When the pin filter flushing water supply device of the practical circulating water storage toilet is used, the filtered circulating water is effectively utilized, the consumption of water resources is reduced, and the leakage of odor of circulating water is effectively avoided, which is more convenient to use and promote.

[0030] The problem solved by the present invention is that the pin filter type flushing water supply device of the circulating water storage toilet cannot have the function of improving the utilization rate of circulating water and reducing odor. The utilization rate of circulating water is low, and the odor associated with the stored circulating water is easy to leak, which brings inconvenience to use. The present invention realizes that the pin filter type flushing water supply device of the circulating water storage toilet can effectively use the filtered circulating water for flushing through the mutual combination of the above-mentioned components, thereby improving the utilization rate and saving water resources. At the same time, it can effectively avoid the leakage of odor, is more hygienic, and is also convenient for promotion and use.

[0031] In embodiment 1 of the present invention, the water tank cover 1 is made of plastic material;

[0032] In embodiment 2 of the present invention, the water tank cover 1 is made of ceramic material;

[0033] In summary, when the water tank cover of the present invention is made of ceramic material, the weight of the present invention is heavier, the fit to the water tank is tighter and does not fall off, the surface is smooth, the dirt is cleaned, it is more hygienic, and the use effect is best.
