Description

Technical Field

[0001] The invention relates to the technical field of pressure-type flushing systems, and in particular to a pressure bag displacement stabilization control structure. Background Art

[0002] The pressure flushing system is a device that uses water pressure for flushing. It is usually used in conjunction with various toilets. Its working principle is to achieve energy conversion through energy storage to form pressure flushing. Specifically, the water from the water supply pipe enters the pressure bag through the water inlet valve and the pressure regulating valve assembly. As the amount of water increases, the air in the pressure bag is continuously compressed to achieve pressurization and energy storage. When the toilet needs to be flushed, the user operates to open the valve, and the pressure in the pressure bag quickly flushes the water to the toilet pipe for flushing.

[0003] As an important component for water storage and pressure accumulation of the entire system, the pressure bag has a huge impact on the system's displacement. In the prior art, the displacement of the pressure bag will change due to differences in water inlet pressure. Specifically, the smaller the water inlet pressure, the less water is pre-stored in the pressure bag, and the less water can be discharged; conversely, the greater the water inlet pressure, the more water is pre-stored in the pressure bag, and the more water can be discharged. The displacement of a conventional pressure bag fluctuates significantly with the change of the water inlet pressure, resulting in uncontrollable displacement of the pressure bag. The corresponding solution is to set a pressure-stabilizing valve at the water inlet end of the pressure bag. However, the water inlet pressure and the water connection conditions will affect the performance of the pressure-stabilizing valve, resulting in inaccurate pressure control, which in turn makes the water inlet of the pressure bag unstable, that is, the displacement is unstable. Summary of the invention

[0004] The purpose of the present invention is to provide a pressure bag displacement stability control structure to solve the problems existing in the prior art. In order to achieve the above object, the solution of the present invention is: A pressure bag displacement stabilization control structure comprises a pressure bag body and a floating member; a water storage chamber is arranged in the pressure bag body, a partition is arranged on the upper part of the water storage chamber, and an air vent is arranged on the partition; the floating member floats and fits under the air vent as the water level of the water storage chamber changes; when a preset maximum amount of water is reached in the water storage chamber, the air vent is blocked by the floating member.

[0005] The upper surface of the pressure bag body is provided with a medium inlet, and the medium inlet extends downward to form a medium conduit, and the medium conduit passes through the partition and extends to the bottom of the water storage cavity.

[0006] The floating member is a hollow object.

[0007] A guide mechanism is provided between the floating member and the partition plate, and the guide mechanism is used to guide the floating member to move along the axial direction of the vent.

[0008] The guide mechanism includes a plurality of guide posts arranged below the partition and a plurality of guide holes arranged around the floating member, and the guide posts are movably inserted through the guide holes. Preferably, a limit plate is arranged at the lower end of the guide post to prevent the guide hole from being separated from the guide post; the peripheral surface of the floating member is provided with a plurality of fins parallel to the partition, and each fin is provided with the guide hole.

[0009] The guide mechanism includes a plurality of guide posts arranged below the partition and a plurality of guide grooves arranged around the floating member, and the guide posts are movably arranged in the guide grooves. Preferably, the circumference of the floating member is provided with a plurality of pairs of wing plates perpendicular to the partition, and the guide grooves are formed between each pair of wing plates.

[0010] The guide mechanism includes a guide column arranged below the partition and coaxial with the vent, and a guide channel arranged on the upper surface of the floating member, and the guide column is movably arranged in the guide channel. Preferably, the lower part of the guide column is split into a plurality of buckles with hooks facing outwards, and a circle of limiting flanges is arranged at the upper opening of the guide channel, and the buckles are movably hooked on the limiting flanges as the floating member floats up and down.

[0011] The guide mechanism includes a plurality of buckles with hooks facing outwards arranged on the upper surface of the floating member, the buckles form a columnar portion movably penetrated through the vent, and the buckles are movably hooked on the edge of the vent as the floating member floats up and down.

[0012] After adopting the above technical solution, the present invention has the following technical effects: The present invention arranges a partition with an air vent in the water storage chamber, so that the water storage chamber is divided into an air chamber and a water chamber at the upper and lower parts. When the water chamber has not reached the maximum water volume, the pressure bag can normally take in water and compress the air into the air chamber through the air vent. When the water chamber has reached the maximum water volume, the floating part floats up under the buoyancy of the water and blocks the air vent to prevent the water level from continuing to rise. Water cannot enter the air chamber through the air vent, and the pressure bag no longer takes in water. The water volume in the pressure bag will be stabilized at a constant value, thereby achieving the purpose of controlling the maximum water volume of the pressure bag, and the control effect is stable and efficient.

DETAILED DESCRIPTION

[0014] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0016] Through the above scheme, the present invention arranges a partition 12 with an air vent 13 in the water storage chamber 11, so that the water storage chamber 11 is divided into an air chamber and a water chamber at the upper and lower parts. When the maximum water volume is not reached in the water chamber, the pressure bag can normally take in water and compress the air into the air chamber through the air vent 13. When the maximum water volume is reached in the water chamber, the floating part 2 floats up under the buoyancy of the water and blocks the air vent 13 to prevent the water level from continuing to rise. Water cannot enter the air chamber through the air vent 13, and the pressure bag no longer takes in water. The water volume in the pressure bag will be stabilized at a constant value, thereby achieving the purpose of controlling the maximum water volume of the pressure bag, and the control effect is stable and efficient.

[0017] In some embodiments of the present invention, the floating member 2 is a hollow object, thereby reducing weight and increasing buoyancy.

[0018] In some embodiments of the present invention, a guide mechanism is provided between the floating member 2 and the partition 12 to guide the floating member 2 to move along the axial direction of the vent 13 to ensure the stability of the function of the floating member 2 to block the vent 13 .

[0019] See also Figure 1-3 , showing the first embodiment of the present invention.

[0020] In the first embodiment, the guide mechanism includes a plurality of guide posts 14 disposed below the partition 12 and a plurality of guide holes 21 disposed around the floating member 2 , and the guide posts 14 are movably inserted into the guide holes 21 .

[0021] Furthermore, the guide posts 14 are arranged at equal angles around the axis of the vent 13 .

[0022] At the same time, a limit plate 15 is provided at the lower end of the guide column 14 to prevent the guide hole 21 from being separated from the guide column 14. This can limit the travel of the floating member 2 when it moves downward, and prevent the floating member 2 from being separated from the guide column 14. During assembly, the floating member 2 can be first installed on the guide column 14, and then the limit plate 15 can be fixed to the lower end of the guide column 14 by gluing, welding, etc., so that the limit plate 15 and the guide column 14 are combined into a whole, and the floating member 2 is not easy to fall off from the guide column 14, ensuring functional stability.

[0023] Secondly, a plurality of fins 22 parallel to the partition plate 12 are provided on the circumferential surface of the floating member 2, and the guide holes 21 are provided on each fin 22.

[0026] Furthermore, the guide posts 14 are arranged at equal angles around the axis of the vent 13 .

[0027] At the same time, a plurality of pairs of wing plates 24 perpendicular to the partition plate 12 are provided on the circumferential surface of the floating member 2 , and the guide grooves 23 are formed between each pair of wing plates 24 .

[0030] Furthermore, the lower part of the guide column 14 is split into a plurality of buckles 16 with hooks facing outwards, and a circle of limiting flanges 26 are provided at the upper opening of the guide channel 25. The buckles 16 are hooked on the limiting flanges 26 as the floating member 2 floats up and down to prevent the floating member 2 from falling off the guide column 14.

[0031] See also Figure 10-12 , showing a fourth embodiment of the present invention.

[0032] In the fourth embodiment, the above-mentioned guiding mechanism includes a plurality of hooks 27 with outward hooks arranged on the upper surface of the floating member 2. The hooks 27 form a columnar portion that is movably penetrated through the vent 13, and the hooks 27 are hooked on the edge of the vent 13 as the floating member 2 floats up and down.

[0033] In addition, the upper surface of the pressure bag body 1 is provided with a medium inlet 17, which extends downward to form a medium conduit 18, and the medium conduit 18 passes through the partition 12 and extends to the bottom of the water storage chamber 11.
