Description

TECHNICAL FIELD

[0001] The present application relates to the field of toilet flushing control technology, in particular to a toilet flushing control method and a toilet flushing pump. BACKGROUND

[0002] Generally, the water discharged by the water tank drainage mechanism of the toilet is divided into two paths, one of which is diverted to the jetting port at the bottom of the toilet to perform siphon flushing on the bottom dirt, and the other is diverted to the flushing jetting port at the top of the toilet bowl to flush the skirt of the inner wall of the toilet. When in use, the water outlet needs to be switched, and the common switching methods are: setting an electromagnetic valve or a ball valve in the water outlet, but it is prone to have the problem of loud noise, and the switching structure is prone to damage and failure.

[0003] Later, someone studied a new toilet flushing switching structure, which improves the service life of the flushing switching piece, for example, CN 115045370 A discloses a control method and device for toilet flushing, the flushing switching piece and the motor are arranged in the flushing switching device, the flushing switching device further includes a housing assembly, the housing assembly is provided with a water passing cavity, and a water inlet and at least two water outlets are communicated with the water passing cavity. The flushing switching piece includes a rotating shaft and a blocking part arranged on the rotating shaft, the flushing switching piece is arranged in the water passing cavity of the housing assembly, and one end of the rotating shaft of the flushing switching piece is arranged in the shaft hole corresponding to the housing assembly, and is in transmission connection with the output shaft of the motor, so that the rotating shaft is driven by the motor to drive the blocking part to switch the blocking of any water outlet or the opening of each water outlet. The water pump in the toilet pumps liquid (water) into the water inlet, and the position of the blocking part of the flushing switching piece and the at least two water outlets is switched by changing the rotating direction of the motor, so as to realize the diversion and conversion of the water path at the jetting port at the bottom of the inner wall of the toilet and the flushing jetting port at the top of the toilet bowl. However, the blocking part switches the blocking or opening of any water outlet, which depends on the additional motor for driving, and the production cost is high, and the energy consumption is large during use.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. SUMMARY

[0005] Therefore, the present application aims at the defects in the prior art, and the main purpose is to provide a toilet flushing control method and a toilet flushing pump, which uses the water flow impact force when the water pump blade rotates to open / close the baffle of the water outlet, saves the motor for controlling the blocking part, has a simple structure, effectively reduces the production and manufacturing cost, and is more energy-saving during use.

[0006] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] A toilet flushing control method is provided, wherein a first water outlet and a second water outlet are set along the circumferential spacing of the pump blades of the vane pump body, a first swingable baffle and a second swingable baffle are respectively set at the first water outlet and the second water outlet, and the forward and reverse rotation of the motor of the vane pump body is controlled by software, thereby driving the pump blades to switch forward and reverse rotation.

[0008] When the pump blades rotate forward, the force of the water pushes the first swingable baffle to rotate in reverse to open the first outlet, and pushes the second swingable baffle to rotate in reverse to close the second outlet; when the pump blades rotate in reverse, the force of the water pushes the second swingable baffle to rotate forward to open the second outlet, and pushes the first swingable baffle to rotate in forward to close the first outlet.

[0009] A toilet flushing pump includes a housing and a vane pump body disposed within the housing. The vane pump body has pump vanes. A pump chamber is disposed within the housing. An inlet, a first outlet, and a second outlet are disposed on the housing, which penetrate the pump chamber.

[0010] The pump blades can be switched between forward and reverse rotation; the first and second outlets are set with a circumferential spacing corresponding to the pump blades; the first and second outlets are respectively provided with a first swingable baffle and a second swingable baffle; the hinge axis of the first and second swingable baffles is parallel to the rotation axis of the pump blades.

[0011] When the pump blades rotate in the forward direction, the first swingable baffle rotates in the reverse direction around its own hinge axis to open the first outlet. At this time, the second swingable baffle rotates in the reverse direction to block the second outlet, and the first outlet drains water.

[0012] When the pump blades rotate in the reverse direction, the second swingable baffle rotates forward about its own hinge axis to open the second outlet. At this time, the first swingable baffle rotates forward to block the first outlet, and the second outlet drains water.

[0013] As a preferred embodiment, the first outlet and the second outlet are located on the same side of a predetermined diameter of the pump chamber, and the first outlet and the second outlet are located in two adjacent quadrants respectively; the predetermined diameter is the diameter of the rotation circumference of the pump blade.

[0014] As a preferred embodiment, the first and second water outlets are symmetrically arranged.

[0015] As a preferred embodiment, the first swingable baffle is divided into two ends by its own hinge axis, one end of which extends from its own hinge axis toward the side close to the second swingable baffle, and the other end of which extends from its own hinge axis toward the side away from the second swingable baffle.

[0016] The second swingable baffle is divided into two regions by its own hinge axis. One end extends from its own hinge axis toward the side close to the first swingable baffle, and the other end extends from its own hinge axis toward the side away from the first swingable baffle.

[0017] When the pump blades rotate in the forward direction, one end of the first swingable baffle swings toward the outside of the pump chamber under the force of the water to open the first outlet, and the other end of the second swingable baffle swings toward the outside of the pump chamber under the force of the water to close the second outlet.

[0018] When the pump blades rotate in the opposite direction, one end of the second swingable baffle swings toward the outside of the pump chamber under the force of the water to open the second outlet, and the other end of the first swingable baffle swings toward the outside of the pump chamber under the force of the water to close the first outlet.

[0019] As a preferred embodiment, when the pump blades rotate in the opposite direction while the first swingable baffle is blocked at the first outlet, the other end of the first swingable baffle is restricted by the inner wall of the first outlet and cannot swing towards the outside of the pump chamber under the force of the water.

[0020] When the second swingable baffle is blocked at the second outlet, and the pump blades are rotating in the forward direction, the other end of the second swingable baffle is restricted by the inner wall of the second outlet and cannot swing towards the outside of the pump chamber under the force of the water.

[0021] As a preferred embodiment, the blocking width of one end of the first swingable baffle to the first outlet is greater than the blocking width of the other end of the first swingable baffle to the first outlet.

[0022] The sealing width of one end of the second swingable baffle to the second outlet is greater than the sealing width of the other end of the second swingable baffle to the second outlet.

[0023] As a preferred embodiment, a first rotation-limiting stop is provided at the end of the other end of the first swingable baffle, and a second rotation-limiting stop is provided at the end of the other end of the second swingable baffle.

[0024] As a preferred embodiment, the pump blade includes a plurality of blade portions arranged at circumferential intervals, and the blade portions have symmetrically arranged water-repelling surfaces on two opposite sides along the rotation direction, the water-repelling surfaces being convex arc surfaces.

[0025] As a preferred embodiment, the pump blades include an upper blade holder and a lower blade holder assembled in a stacked manner; the blade portions are disposed on the upper blade holder and / or the lower blade holder, and are located on opposite sides of the upper and lower blade holders; a water inlet is centrally located at the top of the upper blade holder; the water inlet, the water inlet connection, the gap between adjacent blade portions, and the pump chamber are all included in the design.

[0026] Connect them sequentially.

[0027] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the force of water flow when the pump blades rotate to open / close the baffle of the outlet, so that when the pump is working in the forward direction, the first outlet is opened and the second outlet is closed, and when the pump is working in the reverse direction, the first outlet is closed and the second outlet is opened. This eliminates the need for a motor for controlling the sealing part, and its structure is simple, effectively reducing production costs and making it more energy-efficient in use.

Implementation

[0040] Please refer to Figures 1 to 10 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0041] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they cannot be used to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation.

[0042] This is to be understood as a limitation of the present invention.

[0043] A toilet flushing control method is disclosed, which realizes automatic control of the toilet's top flush and bottom flush by a water pump. The water pump is a vane pump, which includes a vane pump body, a motor, and pump blades driven by the motor. Currently, the top flush and bottom flush of toilets are drained from two different water outlets. In this embodiment, they are defined as a first water outlet 1 and a second water outlet 2. The first water outlet 1 and the second water outlet 2 are set along the circumferential spacing of the pump blades 4 of the vane pump body 3. A first swingable baffle 5 and a second swingable baffle 6 are respectively set at the first water outlet 1 and the second water outlet 2. The motor of the vane pump body is controlled by software to switch between forward and reverse rotation, thereby driving the pump blades to switch between forward and reverse rotation. It should be noted that the motor that can switch between forward and reverse rotation is already a mature technology. Typically, the motor is connected to a PCBA board, and software is set on the chip or controller of the PCBA board. The software controls the forward and reverse rotation of the motor, and the forward and reverse rotation duration and switching time can be freely set to meet the flushing needs of the toilet's top flush and bottom flush. Pump blades rotate forward 4 (e.g.) Figure 6 When the water is in the direction of R1 (counterclockwise), it undergoes centrifugal motion under the action of centrifugal force, rushing towards the first swingable baffle 5 with a certain speed and pressure. This force pushes the first swingable baffle 5 to reverse (clockwise) to open the first outlet 1, and pushes the second swingable baffle 6 to reverse to close the second outlet 2; while the pump blades 4 reverse (for example...). Figure 6 When the water moves in the direction of R2 (clockwise), it is subjected to centrifugal force and undergoes centrifugal motion, rushing towards the second swingable baffle 6 with a certain speed and pressure. The force pushes the second swingable baffle 6 to rotate clockwise (counterclockwise) to open the second outlet 2, and pushes the first swingable baffle 5 to rotate clockwise to close the second outlet 2.

[0044] A water outlet.

[0045] A toilet flushing pump includes a housing 7 and a vane pump body 3 disposed within the housing 7. The housing 7 has a pump chamber 8, and the housing 7 has an inlet 9, a first outlet 1, and a second outlet 2 that pass through the pump chamber 8.

[0046] The vane pump body 3 has pump blades 4, which can be switched between forward and reverse rotation. Taking the figure as an example, the inlet 9 is set along the rotation axis of the pump blades 4, so that water enters the pump chamber 8 from the rotation axis of the pump blades 4. The first outlet 1 and the second outlet 2 are set with a circumferential distance corresponding to the rotation of the pump blades 4. The first outlet 1 and the second outlet 2 are respectively provided with a first swingable baffle 5 and a second swingable baffle 6. The hinge axis of the first swingable baffle 5 and the second swingable baffle 6 are parallel to the rotation axis of the pump blades 4. When the pump blades 4 rotate in the forward direction, the water rotates with them under the action of the pump blades 4. When the water reaches the first outlet 1, it is subjected to centrifugal force and moves centrifugally. It rushes towards the first swingable baffle 5 with a certain speed and pressure, so that the first swingable baffle 5 rotates in the reverse direction (i.e., clockwise) around its own hinge axis 10 to open the first outlet 1. At this time, the second swingable baffle 6 rotates in the reverse direction to block the second outlet 2, and the first outlet 1 drains water. When the pump blades 4 rotate in the reverse direction, the water rotates accordingly under the action of the pump blades 4. When it reaches the second outlet 2, the water undergoes centrifugal motion under the action of centrifugal force, and it rushes towards the second swingable baffle 6 with a certain speed and pressure, causing the second swingable baffle 6 to rotate in the forward direction around its own hinge axis 11.

[0047] (i.e., counterclockwise) to open the second outlet 2. At this time, the first swingable baffle 5 rotates in the forward direction to block the first outlet 1, and the second outlet 2 drains water.

[0048] Preferably, the first outlet 1 and the second outlet 2 are located on the same side of a predetermined diameter of the pump chamber 8 (e.g., Figure 6 The diameter is defined as the diameter along the direction of the dashed line L, and the first outlet 1 and the second outlet 2 are located in two adjacent quadrants; the set diameter is the diameter of the rotation circumference of the pump blade 4. The first outlet 1 and the second outlet 2 are symmetrically arranged.

[0049] In this embodiment, the outer surface of the housing 7 extends to form a first water outlet channel 12 and a second water outlet channel 13 corresponding to the first water outlet 1 and the second water outlet 2, respectively. The first water outlet channel 12 and the second water outlet channel 13 extend parallel to each other and are perpendicular to the aforementioned set diameter. The first water outlet channel 12 and the second water outlet channel 13 correspond to the corresponding first water outlet 1 and the second water outlet 2 to form drainage in the tangential direction of water rotation. Normally, the first water outlet 1 and the second water outlet 2 are located within a 60-degree angle range in the center of their respective quadrants, and they are arranged in a V-shape. Similarly, when both the first water outlet 1 and the second water outlet 2 are blocked, the first swingable baffle 5 and the second swingable baffle 6 are arranged in a V-shape. When no external force is applied (e.g., the force of water), the first swingable baffle 5 and the second swingable baffle 6 maintain the blocking state of the corresponding first water outlet 1 and the second water outlet 2. The degree of sealing depends on the first swingable baffle 5 and the second swingable baffle 6.

[0050] The precision of the matching between the swing baffle 6 and the corresponding first water outlet 1 and second water outlet 2 is generally not required to be completely sealed for the needs of toilet flushing. Slight leakage is still within the allowable range for practical applications.

[0051] The first swingable baffle 5 is divided into two ends by its own hinge axis 10. One end 51 of the first swingable baffle extends from its own hinge axis 10 toward the side closer to the second swingable baffle 6, and the other end 52 of the first swingable baffle extends from its own hinge axis 10 toward the side away from the second swingable baffle 6.

[0052] One end 51 of the swing baffle and the other end 52 of the first swingable baffle can swing relative to the hinge axis 10 of the first swingable baffle, with the hinge axis 10 of the first swingable baffle serving as the swing fulcrum.

[0053] The second swingable baffle 6 is divided into two ends by its own hinge axis 11. One end 61 of the second swingable baffle extends from its own hinge axis 11 toward the side closer to the first swingable baffle 5, and the other end 62 extends from its own hinge axis 11 toward the side away from the first swingable baffle 5.

[0054] One end 61 of the swing baffle and the other end 62 of the second swing baffle can swing relative to the hinge axis 11 of the first and second swing baffles. The hinge axis 11 of the second swing baffle serves as the swing fulcrum.

[0055] When the pump blade 4 rotates in the forward direction, one end 51 of the first swingable baffle swings outward toward the pump chamber 8 under the force of the water to open the first outlet 1. At this time, both one end 51 and the other end 52 of the first swingable baffle are open, with the other end 52 extending into the pump chamber 8. The other end 62 of the second swingable baffle swings outward toward the pump chamber 8 under the force of the water to close the second outlet 2. When the second swingable baffle 6 is blocking the second outlet 2, and the pump blade 4 continues to rotate in the forward direction, the other end 62 of the second swingable baffle is restricted by the inner wall of the second outlet 2 and cannot swing outward toward the pump chamber 8 under the force of the water.

[0056] When the pump blade 4 rotates in the opposite direction, one end 61 of the second swingable baffle swings toward the outside of the pump chamber 8 under the force of the water to open the second outlet 2. At this time, one end 61 and the other end 62 of the second swingable baffle are both in the open state, and the other end 62 of the second swingable baffle extends into the pump chamber 8. The other end 52 of the first swingable baffle swings toward the outside of the pump chamber 8 under the force of the water to close the first outlet 1. When the first swingable baffle 5 is blocked at the first outlet 1, and the pump blade 4 continues to rotate in the reverse direction, the other end 52 of the first swingable baffle is restricted by the inner wall of the first outlet 1 and cannot swing outwards from the pump chamber 8 under the force of the water. The blocking width of one end 51 of the first swingable baffle at the first outlet 1 is greater than the blocking width of the other end 52 of the first swingable baffle at the first outlet 1. The blocking width of one end 61 of the second swingable baffle at the second outlet 2 is greater than the blocking width of the other end 62 of the second swingable baffle at the second outlet 2. A first rotation-limiting stop 14 is provided at the end of the other end 52 of the first swingable baffle. When the pump blade 4 rotates in the reverse direction, the force of the water acts on the other end 52 of the first swingable baffle and the first rotation-limiting stop 14, causing the other end 52 of the first swingable baffle to swing outwards from the pump chamber 8 under the force of the water to close the first outlet 1.

[0057] Then, the first rotation-limiting stop 14 abuts against the inner wall of the first outlet 1, preventing it from continuing to swing outwards from the pump chamber 8 under the force of the water, thus maintaining the closed state. The other end 62 of the second swingable baffle extends to a second rotation-limiting stop 15. When the pump blade 4 rotates forward, the force of the water acts on the other end 62 of the second swingable baffle and the second rotation-limiting stop 15, causing the other end 62 of the second swingable baffle to swing outwards from the pump chamber 8 under the force of the water to close the second outlet 2. After closing the second outlet 2, the second rotation-limiting stop 15 abuts against the inner wall of the second outlet 2, preventing it from continuing to swing outwards from the pump chamber 8 under the force of the water, thus maintaining the closed state. Here, the first rotation-limiting stop 14 and the other end 52 of the first swingable baffle form a V-shape or a V-like shape, and the second rotation-limiting stop 15 and the other end 62 of the second swingable baffle form a V-shape or a V-like shape.

[0058] The pump blade 4 includes a plurality of blade portions 16 arranged at circumferential intervals. Each blade portion 16 has symmetrically arranged water-dispelling surfaces 17 on two opposite sides along the rotation direction. The water-dispelling surfaces 17 are preferably convex arc surfaces, which have low energy loss and high efficiency when dispelling water. The pump blade 4 includes an upper blade holder 18 and a lower blade holder 19 assembled in a stacked manner. The blade portions 16 are disposed on the upper blade holder 18 and / or the lower blade holder 19, and located on opposite sides of the upper blade holder 18 and the lower blade holder 19. A water inlet 20 is centrally located at the top of the upper blade holder 18. The water inlet 9, the water inlet 20, the gap 21 between adjacent blade portions 16, and the pump chamber 8 are sequentially connected. In this embodiment, as... Figure 8 and Figure 9 As shown, the blade portion 16 is integrally formed on the bottom of the upper blade holder 18. A positioning protrusion 22 is provided downward at the bottom of the blade portion 16. A connecting post 23 extends further downward from the bottom of each positioning protrusion 22. Correspondingly, a positioning groove 24 is provided on the top of the lower blade holder 19. A connecting groove 25 is provided through the bottom of the positioning groove 24. The connecting groove 25 extends through the bottom of the lower blade holder 19. The positioning protrusion 22 is embedded in the corresponding positioning groove 24, and the connecting post 23 is embedded in the corresponding connecting groove 25. The assembly can be strengthened by gluing, welding, or other methods. Alternatively, screws can be used for further fastening.

[0059] In this embodiment, the housing 7 is designed as three parts, so as to Figure 1 and Figure 3As shown, the housing 7 is divided into three parts: an upper housing 26, a lower housing 27, and a bottom cover 28. The water inlet 9, the first water outlet 1, and the second water outlet 2 are all located on the upper housing 26. A positioning and diverting shaft 29 is provided inside the water inlet 9 of the upper housing 26. The upper end of the positioning and diverting shaft 29 is integrally connected to the inner wall of the water inlet 9 through several partitions 30. The space between adjacent partitions 30 forms a diversion groove 31. This facilitates a more uniform gap 21 between adjacent blade sections 16 when water enters. Preferably, the diversion grooves 31 are set one by one to correspond to the gaps 21. At the same time, the positioning and diverting shafts are used to achieve a more uniform gap 21 between adjacent blade sections 16. The lower end of the flow shaft 29 passes through the center of the lower blade holder 19 and abuts against the upper end of the rotor shaft 32. A first shim 33 is provided between the lower end of the positioning flow shaft 29 and the upper end of the rotor shaft 32. The first shim 33 can be made of a material that is resistant to friction and has a low coefficient of friction. Similarly, a protruding post 35 is provided on the inner bottom of the inner shell 34. The top end of the protruding post 35 supports the lower end of the rotor shaft 32. A second shim 36 can also be provided between the top end of the protruding post 35 and the lower end of the rotor shaft 32. The second shim 36 can be made of a material that is resistant to friction and has a low coefficient of friction. The lower housing 27 includes an inner housing 34 and an outer housing 37 integrally connected to the periphery of the inner housing 34. The inner housing 34 is a waterproof housing with an open top. The outer ring side of the inner housing 34 is integrally connected to the top of the outer housing 37 via an annular top. An annular cavity 38 is formed between the outer ring side of the inner housing 34 and the inner ring side of the outer housing 37. The stator 44 of the vane pump body 3 is inserted into the annular cavity 38 from the bottom of the lower housing 27. Then, the bottom cover 28 is assembled to the bottom of the lower housing 27.

[0060] An assembly annular wall 39 extends upward from the periphery of the assembly annular wall 39, and an annular groove 40 is provided in the same direction on the assembly annular wall 39. The bottom end of the lower housing 27 is inserted into the annular groove 40 for positioning (fixing methods such as adhesive or welding are acceptable). The wire can be extended from the wire hole 41 at the bottom of the bottom cover 28, while the rotor 42 is installed from the top of the inner housing 34. The water pump blade 4 is installed on the rotor 42. Finally, the upper housing 26 is placed on top of the lower housing 27 and connected and locked with screws 43.

[0061] The key design feature of this invention is that it utilizes the force of water flow when the pump blades rotate to open / close the baffle at the outlet. This allows the first outlet 1 to open and the second outlet 2 to close when the pump rotates forward, and the first outlet 1 to close and the second outlet 2 to open when the pump rotates in reverse. This eliminates the need for a motor to control the sealing mechanism, resulting in a simple structure and effectively reducing [damage / loss].

[0062] It has low production costs and is more energy-efficient during use. In addition, its overall structural design is ingenious, the overall water pump structure is compact, and it is easy to manufacture and assemble.

[0063] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
