Description

Technical Field

[0001] This invention belongs to the field of sanitary building materials technology, specifically, it relates to a toilet flushing actuator. Background Technology

[0002] Traditional toilets on the market currently rely on manual flushing. Most people only press the flush button after using the toilet, leading to repeated flushing. This process makes the button dirty and unhygienic, increasing the risk of microorganisms invisible to the naked eye, such as viruses, bacteria, fungi, or parasites that can cause infectious diseases. With societal development, people have begun using smart toilets, which bring great convenience. Smart toilets automatically recognize when someone has used the toilet and flush, eliminating the need for manual flushing. However, these automatic flushing smart toilets are integrated smart toilet systems, which are more expensive and not suitable for most budget-conscious users.

[0003] In existing technologies, traditional side-flush toilets can be converted into smart toilets by adding an automatic flushing device, without replacing the entire toilet. For example, the automatic flushing device can be installed in the button hole on the toilet tank lid or added to the side wall of the toilet, driving the drain valve in the tank for automatic flushing. However, automatic flushing devices are relatively large, costly, require additional installation space, and are aesthetically unappealing to the toilet.

[0004] In view of this, the present invention is proposed. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] like Figures 1 to 5 As shown, the toilet flushing actuator 4 of the present invention includes a housing 41, a drive module 42, and a trigger 43. The toilet flushing actuator 4 can be added inside the water tank 2 of a conventional toilet 1, enabling the conventional toilet 1 to flush automatically without the need to manually press the flushing button 3 on the toilet 1.

[0050] The housing 41 has a mounting part 44 at one end for connecting to the flushing press device 3 on the side of the water tank 2 of the toilet 1. The trigger 43 is inserted into the housing 41, with one end connected to the valve chain 5 inside the water tank 2. The drive module 42 is installed inside the housing 41. The drive module 42 is connected to the other end of the trigger 43 and is used to drive the trigger 43 to move up and down, thereby opening or closing the flushing valve plug 6 connected to the valve chain 5 by pulling the valve chain 5 up or down.

[0051] The flushing actuator 4 of the present invention can be added to the water tank 2 of a traditional toilet 1. The mounting part 44 of the flushing actuator 4 is installed on the flushing press device 3 on the side of the water tank 2 of the toilet 1. It retains the manual flushing function of the traditional toilet 1, and can also drive the trigger 43 to move upward to open the flushing valve plug 6 of the water tank 2 for flushing through the drive module 42 of the flushing actuator 4. The toilet 1 can be automatically flushed without the user having to manually press the flushing press device 3 on the toilet 1, thus avoiding cross-infection of bacteria. The flushing actuator 4 occupies little space, is easy to install, and has low cost.

[0052] The flushing device 3 in a conventional toilet 1 includes a push button 31 and a suspension rod 32. The push button 31 is installed on the side wall of the toilet tank 2. One end of the suspension rod 32 is connected to the push button 31, and the other end extends into the tank 2 and is connected to the valve chain 5. A flushing valve plug 6 is provided at the bottom of the tank 2. One end of the flushing valve plug 6 is connected to the bottom hinge, and the other end is connected to the valve chain 5.

[0053] When the user flushes, pressing down on the button 31 will cause the other end of the suspension rod 32 to move upward, which in turn causes the valve chain 5 to move upward and open the flush valve plug 6.

[0054] The flushing actuator 4 of the present invention can be added to the water tank 2 of a conventional side-press flush toilet 1. The user can press the button 31 on the side of the toilet 1 to move the other end of the suspension rod 32 upward, causing the flushing actuator 4 to move upward as well, which in turn moves the valve chain 5 upward to open the flushing valve plug 6 for flushing; or the flushing actuator 4 can be used for automatic flushing.

[0055] like Figures 2 to 3 As shown, in one embodiment, the mounting part 44 of the present invention includes a protrusion 441, which is provided with a mounting hole for mounting on a suspension rod 32 extending into the water tank 2 via a connector 442.

[0056] Specifically, the protrusion 441 is a U-shaped plate, and the opening 413 of the U-shaped plate is fixed on the side wall of the housing 41, near one end face. The protrusion 441 has mounting holes along the vertical direction.

[0057] One end of the connector 442 is a screw, which is installed in the mounting hole on the protrusion 441. The other end of the connector 442 is a hook, which is hung in the mounting hole on the suspension to suspend the toilet 1 actuator on the suspension rod 32.

[0058] like Figures 4 to 5 As shown, in another embodiment, the mounting part 44 of the present invention includes a suspension device 443 for fixing and suspending the toilet 1 flushing actuator 4 on the suspension rod 32 that extends into the water tank 2 from the flushing press device 3.

[0059] Specifically, the suspension device 443 is a hook, which is set on the end face of one end of the housing 41 and hung in the mounting hole on the suspension rod 32 to suspend the toilet 1 actuator on the suspension rod 32.

[0060] like Figures 2 to 3 As shown, in one embodiment, the drive module 42 includes a retractable airbag 421, an air inlet 411, and an air outlet 412.

[0061] The retractable airbag 421 is installed inside the housing 41 and is designed for retractable movement between one end and the other end of the housing 41. The airbag 421 extends from one end of the housing 41 to the other end, or retracts from the other end of the housing 41 to one end. Preferably, the sidewall of the retractable airbag 421 has a deformable folding structure, maintaining a certain retracted state in the uninflated state.

[0062] The air inlet 411 is disposed on the housing 41 and communicates with one end of the airbag 421. The air outlet 412 is disposed on the housing 41 and communicates with one end of the airbag 421, and the diameter of the air outlet 412 is smaller than the diameter of the air inlet 411.

[0063] Gas is injected into the retractable airbag 421 through the air inlet 411, causing the retractable airbag 421 to increase in volume and move to the other end of the housing 41.

[0064] The other end of the airbag 421 is connected to the trigger 43, and is used to move the trigger 43 after air is introduced or released.

[0065] Specifically, after air enters the airbag 421 through the air inlet 411, the amount of gas entering the airbag 421 is greater than the amount of gas released from the air outlet 412, causing the volume of the airbag 421 to increase and move towards the other end of the housing 41. When the amount of air entering is less than the amount of air exiting, the volume of the airbag 421 decreases and retracts towards one end of the housing 41, causing the trigger 43 to move. Since the trigger 43 is connected to the valve chain 5 of the toilet 1, it will drive the flush valve plug 6 connected to the valve chain 5 to move up and down, causing the toilet 1 to flush or stop flushing.

[0066] The drive module 42 of the present invention has a retractable airbag 421 set in the housing 41. The airbag 421 retracts and moves the trigger 43 back and forth, causing the trigger 43 to move the valve chain 5 up and down, thereby opening or closing the flush valve plug 6. It has a simple structure, low cost, and does not require a circuit structure in the housing 41. It has the advantages of high safety and long service life.

[0067] One end of the airbag 421 is positioned opposite to one end of the housing 41, and the air inlet 411 and the air outlet 412 are located on one end of the housing 41.

[0068] Preferably, one end of the airbag 421 is fixed in one end of the housing 41 and is sealed to the housing 41. One end of the airbag 421 has an airbag opening 413, and the opening 413 has an outwardly turned lip, which is sealed to one end of the housing 41. The airbag opening 413 is opposite to the port of the housing 41. One end of the housing 41 is provided with an air inlet 411 and an air outlet 412 communicating with the airbag opening 413.

[0069] Preferably, the air inlet 411 and the air outlet 412 are located on the end face of the housing 41. There are two air outlets 412.

[0070] Furthermore, the trigger 43 includes a first trigger 431 and a second trigger 432. One end of the first trigger 431 is connected to the other end of the retractable airbag 421. One end of the second trigger 432 is pivotally connected to the other end of the first trigger 431.

[0071] Preferably, the other end of the airbag 421 is provided with a connecting post 4211, the first trigger 431 is a connecting rod, and the end of the connecting rod connected to the connecting post 4211 is cylindrical and sleeved on the connecting post 4211 of the airbag 421.

[0072] An opening 413 is provided on the side wall of the housing 41, and the second trigger 432 passes through the opening 413. The other end of the second trigger 432 is located outside the housing 41 and is used to connect with the valve chain 5 inside the water tank 2.

[0073] The second trigger 432 is located in the opening 413. When the first trigger 431 moves up and down, the lever principle is used to move the other end of the second trigger 432 up and down, thereby driving the valve sub-chain 5 to move up and down. The other end of the second trigger 432 is provided with a mounting hole for connecting to the valve sub-chain 5.

[0074] Preferably, the first trigger 431 is a connecting rod, and the second trigger 432 is a connecting plate.

[0075] Furthermore, a first guide rail 47 is provided inside one end of the housing 41, and the airbag 421 is retractably located inside the first guide rail 47.

[0076] The other end of the housing 41 is provided with a second guide rail 48, which is connected to the first guide rail 47. The width of the second guide rail 48 is smaller than the width of the first guide rail 47. Part of the trigger 43 moves back and forth between the first guide rail 47 and the second guide rail 48.

[0077] The folding structure of the airbag 421 can extend and retract along the first guide rail 47. The first guide rail 47 and the second guide rail 48 are cylindrical, cuboid, or prismatic.

[0078] The second guide rail 48 has vertically extending guide rail openings (not shown in the figure), and the second trigger 432 passes through the guide rail openings and moves vertically along the guide rail openings. Preferably, the guide rail openings connect the upper and lower ends of the second guide rail 48.

[0079] By setting a first guide rail 47 and a second guide rail 48, the present invention allows the retractable airbag 421 to move back and forth within the first guide rail 47, which ensures that the first trigger 431 moves smoothly back and forth between the first guide rail 47 and the second guide rail 48, and ensures that the second trigger 432 can move up and down without deviation, thus ensuring that the flush valve 6 of the toilet 1 can be opened.

[0080] The drive module 42 also includes a guide 46, one end of which is connected to the other end of the airbag 421, and is sleeved between the connection between the trigger 43 and the airbag 421 and the first guide rail 47, for moving along the first guide rail 47.

[0081] The other end of the guide member 46 is sleeved on the end of the trigger member 43 connected to the airbag 421, and is located inside the second guide rail 48. It is used to move back and forth between the first guide rail 47 and the second guide rail 48 to maintain the stability of the moving direction of the first trigger member 431.

[0082] The opening 413 is disposed on the side wall opposite to the second guide rail 48. The width of the opening 413 in the vertical direction is greater than the width of the second trigger 432. Preferably, the opening 413 is disposed opposite to the middle portion of the second guide rail 48. The width of the opening 413 is ≥ twice the width of the second trigger 432.

[0083] like Figures 4 to 5 As shown, in another embodiment, the trigger 43 is a strip 433, one end of which is used to connect to the valve sub-chain 5 and drive the valve sub-chain 5 to move up and down.

[0084] The drive module 42 includes a winding device 423 for winding up the cable tape 433, the other end of which is wound around the winding device 423.

[0085] The other end of the housing 41 is provided with a cable outlet 414, and one end of the cable 433 passes through the cable outlet 414 and connects to the valve chain 5. Preferably, a sealing structure is provided between the cable outlet 414 and the cable 433.

[0086] The winding device 423 includes a motor and a winding reel. The output shaft 422 of the motor is connected to the central shaft of the winding reel, driving the winding reel to rotate forward or backward. The cable 433 is wound around the winding reel.

[0087] In this embodiment, the motor can be, but is not limited to, a stepper motor. The highest position of the conveyor belt 433 is the position where the conveyor belt 433 drives the valve chain 5 to move upward and open the flush valve plug 6. This can be achieved by setting the number of steps of the stepper motor or the limit switch 452. The lowest position of one end of the conveyor belt 433 is the position where the stepper motor drives the conveyor belt 433 back. This can be controlled by the number of steps of the stepper motor.

[0088] The motor is located behind the winding reel. The motor is housed in a motor housing, and the output shaft extends forward from the motor housing and is connected to the central shaft of the winding reel for transmission.

[0089] Furthermore, the toilet 1 flushing actuator 4 also includes a limiting mechanism 45. The limiting mechanism 45 includes a trigger part 451 and a limit switch 452, which are used to provide a trigger signal to the motor to stop the motor from running.

[0090] The trigger part 451 is disposed on one side of the winding reel and extends along the axial direction of the winding reel. The trigger part 451 is disposed on the outer peripheral edge of the rear side of the winding reel and has a columnar structure. The limit switch 452 is located inside the housing 41 and is disposed on the path of rotation of the trigger part 451, and is used to receive trigger signals.

[0091] The limit switch 452 includes a trigger spring 453. The upper end of the trigger spring 453 is rotatably connected to the housing 41, and one side of the lower end of the trigger spring 453 abuts against the switch of the limit switch 452, while the other side is located on the rotation path of the trigger part 451. When the trigger part 451 rotates to the trigger spring 453, it drives the lower end of the trigger spring 453 to move and trigger the limit switch 452.

[0092] Specifically, a columnar protrusion is provided on the front side of the motor housing, and one end of the trigger spring 453 is sleeved on the columnar protrusion and rotatably connected to the columnar protrusion.

[0093] The motor is connected to the limit switch 452 and is used to receive the trigger signal from the limit switch 452 to control the motor to stop running for a certain period of time. After the motor stops running for a certain period of time, water flows into the water tank 2 to flush and drain the toilet 1. Then the motor reverses and the control cable 433 returns to its original path, closing the valve plug of the water tank 2 to fill with water.

[0094] By setting a limiting mechanism 45, the present invention can further ensure the accurate movement position of the conveyor belt 433, and can correctly open or close the flushing valve plug 6 in the water tank 2.

[0095] The present invention also provides a smart toilet 1, which has any of the above-described toilet 1 flushing actuators 4, and can flush automatically without manual flushing.

[0096] The smart toilet 1 has a flushing actuator 4 installed in the water tank 2. The flushing actuator 4 is located between the flushing press device 3 and the valve chain 5, which enables automatic flushing and avoids cross-infection of bacteria. The flushing actuator 4 is located between the flushing press device 3 on the toilet 1 and the valve chain 5 in the water tank 2, which occupies little space, is easy to install, and has a lower cost.

[0097] The toilet flushing actuator 4 of the present invention also includes a control module (not shown in the figure), which is communicatively connected to the motor. The user can control the flushing actuator 4 inside the toilet to perform flushing through the control module.
