Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and particularly to an automatic driving unit for a tray drain valve and a drain valve assembly.

Background Art

[0002] A tray is a common utensil in people's lives. With the development of science and technology, the types of trays are increasing more and more. In particular, smart toilets are becoming more and more popular among people. For a smart toilet, a method of realizing automatic drainage of the toilet tank is a main function of the smart toilet. The drain valve is a main drainage structure of the toilet, and the drainage of the current technology smart toilet is mainly realized by electric control. Specifically, electromagnetic valves are installed at the water outlet and water inlet of the toilet tank respectively, a controller and other control components are installed, and a corresponding control program is set inside the controller, so that the controller controls the state of the electromagnetic valve to realize automatic flushing of the toilet. However, such a drainage system of a smart toilet is realized by coordinating a plurality of electric control components with each other. On the one hand, the structure is complex and the cost is high. On the other hand, since the drain valve is installed in the tank, the probability that the electric control components are immersed in water for a long time and fail is high. In later repairs, it is common to replace the corresponding electric control components, and the repair cost is also high.

[0003] Therefore, the toilet drainage structure of the current technology has problems of low stability and high repair cost.

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to solve the problems that the stability of the toilet drainage structure in the prior art is poor and the maintenance cost is high.

Means for Solving the Problems

[0005] In order to solve the above technical problems, in one embodiment based on the present invention, there is provided an automatic drive unit for a toilet drain valve, which has a water inlet communicating with a tank located on a side wall, a valve box having a drain outlet located at one end, a valve core provided in the valve box and sealingly contacting the drain outlet in an openable and closable manner, and a slider provided at the other end of the valve box and drivingly connected to the valve core.

[0006] Furthermore, the automatic drive unit includes a drive member and an actuator member provided in the valve box. Among them, the actuator is fixedly provided in the valve box and includes a fixing member located between the valve core and the slider, and a movable member provided on the fixing member so as to be movable along the axial direction of the valve box with respect to the fixing member and drivingly connected to the valve core.

[0007] The drive member is provided outside the valve box, drivingly connected to the movable member, and driving the movable member to move with respect to the fixing member. And the drive member is electrically connected to an induction member provided on the toilet for collecting the user's body information, converting it into an electrical signal and transferring it to the drive member.

[0008] According to the above technical solution, the automatic drive unit based on this embodiment is directly integrated into the drain valve of the toilet and can directly drive the drain valve valve core. By adopting the automatic drive unit with such a structure for the drain valve, while making use of the conventional functions of the drain valve, it is possible to automatically drive the valve core, eliminating the need for manual operation and having the advantage of good usability.

[0009] In addition, since the actuator of the automatic drive unit is installed above the valve core in the valve box, the drain valve not only increases the occupied space but also enables automatic drainage. Moreover, the transmission distance between the actuator and the valve core is short, resulting in high transmission efficiency.

[0010] In addition, when retrofitting the automatic drive unit to the drain valve, it can be directly installed between the slider and the valve core without the need to improve other structures of the drain valve. Even if any component fails after long-term use, only the relevant component needs to be repaired or replaced, without affecting other components. Also, since the drain valve retains its conventional function, normal drainage of the toilet will not be affected even if the automatic drive unit fails.

[0011] Therefore, when the automatic drive unit based on this embodiment is applied to a toilet, it can improve the usability of the toilet, has good use stability, and has the advantage of low maintenance cost.

[0012] Furthermore, in a preferred embodiment based on the present invention, an automatic drive unit for a toilet drain valve is disclosed. Among them, the fixed member has a housing that is fitted into the valve box and fixed to the inner wall surface of the valve box.

[0013] The movable member is a piston fitted inside the housing. One end of the piston protrudes from the end of the housing close to the valve core and is fixedly connected to the end of the valve core. Alternatively, the movable member is a piston fitted inside the housing. One end of the piston protrudes from the end of the housing away from the valve core and is fixedly connected to the inner end of the slider.

[0014] In the solution based on this embodiment adopting the above technical solution, the movable member directly drives the valve core to open and close the drain valve, and its transmission path is short. When the automatic drive unit is retrofitted to the drain valve, it contributes to improving the transmission efficiency between the automatic drive unit and the drain valve core.

[0015] In another solution based on this embodiment, the movable member drives the slider, and in conjunction with the conventional transmission method between the slider and the valve core, it opens and closes the valve core, enabling automatic drive without changing the conventional transmission principle of the drain valve. It not only has a simple structure but also makes the transmission principle simpler.

[0016] Furthermore, in a preferred embodiment according to the present invention, the automatic driving unit of the toilet flushing valve includes a pressure adjusting member. The housing is a sealed housing in which a sealed chamber is formed inside. The piston includes a piston body and a piston rod. The piston body is slidably connected relatively inside the sealed chamber. Among them, when one end of the piston protrudes from one end close to the valve core of the housing and is fixedly connected to the end of the valve core, a through hole is formed at one end of the housing close to the valve core. One end of the piston rod is fixedly connected to the piston body, the other end passes through the through hole and is fixedly connected to the valve core, and the outer wall surface of the piston rod is sealingly connected to the inner wall surface of the through hole. The pressure adjusting member and the sealed chamber communicate with each other through a pressure pipeline penetrating the valve box and the side wall of the housing. Alternatively, when one end of the piston protrudes from one end away from the valve core of the housing and is fixedly connected to the inner end of the slider, a through hole is formed at the other end of the housing close to the slider. One end of the piston rod is fixedly connected to the piston body, the other end passes through the through hole and is fixedly connected to the inner end of the slider, and the outer wall surface of the piston rod is sealingly connected to the inner wall surface of the through hole. The pressure adjusting member and the sealed chamber communicate with each other through a pressure pipeline penetrating the valve box and the side wall of the housing.

[0017] According to the above technical solution, in this embodiment, when the housing as a sealed housing is installed in the valve box, since the housing has a sealed structure, there is no interference with the normal operation of the actuator due to the water pressure in the valve box.

[0018] In addition, since the pressure adjusting member is adopted for the driving member and has the advantage that the pressure transmission is easy to layout, this method is adopted in the present invention, and the automatic driving unit is easily integrated with the flushing valve of the toilet.

[0019] Furthermore, in a preferred embodiment based on the present invention, there is disclosed an automatic drive unit for a toilet flushing valve, characterized in that the pressure adjusting member includes a hydraulic pump or an air pump.

[0020] Furthermore, in a preferred embodiment based on the present invention, the fixed member includes an electromagnetic member provided in the housing, the movable member is a magnetic induction member disposed opposite to the electromagnetic member, and the drive member is a power source. Therein, when one end of the piston protrudes from the end near the valve core of the housing and is fixedly connected to the end of the valve core, one of the electromagnetic member and the magnetic induction member is fixedly connected in the housing, and the other is movably provided in the housing, interposed between the electromagnetic member and the valve core, and fixedly connected to the valve core. Alternatively, when one end of the piston protrudes from the other end away from the valve core of the housing and is fixedly connected to the inner end of the slider, one of the electromagnetic member and the magnetic induction member is fixedly connected in the housing, and the other is movably provided in the housing, interposed between the electromagnetic member and the slider, and fixedly connected to the slider.

[0021] According to the above technical solution, in order to realize the movement of the movable member by utilizing the repulsive force between the electromagnetic member and the magnetic induction member, there is no need to provide a separate drive, the structure becomes simpler, and it contributes to further simplifying the structure of the flushing valve using the automatic drive unit based on the present invention and reducing the retrofit cost.

[0022] Furthermore, in a preferred embodiment based on the present invention, there is disclosed an automatic drive unit for a toilet flushing valve, characterized in that the housing is a sealed housing, and both the electromagnetic member and the magnetic induction member are installed in the housing.

[0023] According to the above technical solution, by making the housing a closed housing, the electromagnetic member and the magnetic induction member are independent of each other from the water in the valve box. When the valve core moves in conjunction due to the repulsive action between the electromagnetic member and the magnetic induction member, the water pressure in the valve box does not affect the repulsive force between the electromagnetic member and the magnetic induction member. Therefore, the solution disclosed in this embodiment can further improve the stability during the operation of the drain valve.

[0024] Furthermore, in a preferred embodiment based on the present invention, an automatic driving unit of a toilet drain valve is disclosed, which is characterized in that an electromagnet is adopted as the electromagnetic member, and a permanent magnet or a metal block is adopted as the magnetic induction member.

[0025] Furthermore, in a preferred embodiment based on the present invention, the fixed member includes a gear provided in the housing, the movable member is a rack that meshes with the gear and extends in the axial direction of the valve box, the driving member is a motor, and a guide base is provided on the inner wall of the valve box. The rack is slidably connected to the guide base, and the gear is fixedly connected to the output shaft of the motor. An automatic driving unit of a toilet drain valve is disclosed.

[0026] One end of the piston protrudes from one end of the housing close to the valve core and is fixedly connected to the end of the valve core. One end of the rack is fixedly connected to the valve core. Alternatively, one end of the piston protrudes from one end of the housing away from the valve core and is fixedly connected to the inner end of the slider, and the other end of the rack is fixedly connected to the slider.

[0027] According to the above technical solution, in this embodiment, the transmission by a gear and a rack is adopted. Since neither the rack nor the gear is affected by external pressure, the performance becomes more stable when installed in the valve box. In addition, the gear and the rack have the advantage of high transmission accuracy. Therefore, when the valve core is interlocked by the transmission structure of the gear and the rack, the moving displacement of the interlocked valve core becomes more accurate, thereby enabling accurate control of the drainage volume of the toilet and contributing to water conservation.

[0028] Furthermore, in a preferred embodiment based on the present invention, there is disclosed an automatic driving unit for a toilet flushing valve, characterized in that an induction member for detecting human body information of the toilet seat ring and generating an induction signal includes a capacitance sensor or a pressure sensor provided in the toilet seat ring.

[0029] According to the above technical solution, in this embodiment, the induction member is a capacitance sensor or a pressure sensor provided on the toilet seat ring. The capacitance sensor or the pressure sensor can directly detect the characteristic information of the human body and generate an induction signal by its own structure, without the need to provide other signal conversion elements, and the structure becomes simpler.

[0030] Furthermore, in a preferred embodiment based on the present invention, there is disclosed an automatic driving unit for a toilet flushing valve, characterized in that it includes an operation button electrically connected to the driving member and fixed on the outer wall surface of the toilet seat. Among them, by operating the operation button, the driving member actuates the actuator.

[0031] According to the above technical solution, in this embodiment, by providing an operation button on the outer wall surface of the toilet seat, during use, the user can operate the operation button to actively control the automatic driving unit, which has the advantage of excellent stability.

[0032] Furthermore, in a preferred embodiment based on the present invention, there is disclosed an automatic driving unit for a toilet flushing valve, characterized in that the operation button includes a pedestal, a switch provided on the pedestal, and a timing means. The switch has an operation key provided outside the pedestal, and the switch and the timing means are electrically connected. Among them, when the operation key is pressed, the timing means starts timing, the driving member actuates the actuator, and after the timing of the timing means reaches a preset time threshold, the driving member returns the actuator to its initial state.

[0033] According to the above technical solution, in this embodiment, by providing a timing means on the operation button, the automatic drive unit can drive the valve core to open the valve for a certain period of time and then automatically close the valve. This not only improves the degree of automation, but also leads to further rationalization of the drainage volume during toilet flushing, avoiding waste of extra water during toilet flushing.

[0034] Furthermore, in a preferred embodiment based on the present invention, there is disclosed a drainage valve ASSY for a toilet, which comprises a drainage valve and the automatic drive unit, and at least the actuator in the automatic drive unit is provided in the valve box of the drainage valve.

[0035] According to the above technical solution, by providing the automatic drive unit on the toilet, while making use of the conventional functions of the drainage valve, it is possible to automatically drive the valve core, eliminating the need for manual operation and providing the advantage of good usability. In particular, when the automatic drive unit is retrofitted to the drainage valve, it can be directly installed between the slider and the valve core without the need to modify other structures of the drainage valve. Even if any component fails after long-term use, only the relevant component needs to be repaired or replaced, without affecting other components. Also, since the drainage valve retains its conventional functions, the normal drainage of the toilet is not affected even if the automatic drive unit fails. Therefore, by adopting the automatic drive unit with the above-described structure in the toilet disclosed in this embodiment, it is possible to improve the usability of the toilet, and it also has the advantages of good use stability and low maintenance cost.

[0036] The beneficial effects of the present invention are as follows.

By adopting the automatic drive unit with this structure for the drainage valve, while making use of the conventional functions of the drainage valve, it is possible to automatically drive the valve core, eliminating the need for manual operation and providing the advantage of good usability.

[0038] Furthermore, the automatic drive unit includes a drive member and an actuator member provided in the valve box. The actuator is fixedly provided in the valve box and includes a fixed member positioned between the valve core and the slider, and a movable member provided on the fixed member. With the above-described structure, the drain valve increases the occupied space, enables automatic drainage, has the advantages of a short transmission distance between the actuator and the valve core, and high transmission efficiency.

Those of ordinary skill in the art can understand what the above terms specifically mean in this embodiment according to the specific situation.

[0048] To make the purpose, technical solution, and advantages of the present invention clearer, the following will describe the embodiments of the present invention in detail based on the drawings.

[0049] The drain valve is installed in the toilet tank. As shown in FIGS. 1a - 6b, specifically, it has a valve case 110, a valve core 120, and a slider 130. The valve case 110 has a water inlet that communicates the side wall with the tank, and a drain port 111 that communicates one end with the drain port 111. The valve core 120 is installed in the valve case 110 and is in openable and sealed contact with the drain port 111. The slider 130 is installed at the other end of the valve case 110 and is in transmission connection with the valve core 120.

[0050] In the embodiment of the present invention, an automatic driving unit 200 for the toilet drain valve is provided, which can be integrated into the drain valve 100 to automatically operate the valve core 120 and realize the opening and closing of the drain valve 100. Specifically, FIGS. 1a, 2a, 3a, 4a, 5a, 6a show the open state of the drain valve 100, and FIGS. 1b, 2b, 3b, 4b, 5b, 6b show the closed state of the drain valve 100.

[0051] Specifically, the automatic driving unit 200 further includes driving components and execution components installed in the valve case 110. The execution components include fixed components and movable components installed on the fixed components. The fixed components are fixedly installed in the valve case 110, located between the valve core 120 and the slider 130. The movable components are installed to be movable in the axial direction of the valve case 110 relative to the fixed components and are transmission-connected to the valve core 120. The driving components are installed outside the valve case 110, and the driving components drive the movable components to be movable relative to the fixed components.

[0052] Specifically, in this embodiment, the movable components are slidably connected to the fixed components.

[0053] Furthermore, the driving components are electrically connected to sensing components installed on the toilet. The sensing components collect the user's body information, convert it into an electrical signal, and transmit it to the driving components.

[0054] The automatic driving unit 200 provided in this embodiment can be directly integrated into the drain valve 100 of the toilet and can directly drive the valve core 120 of the drain valve 100. By adopting the automatic driving unit 200 with this structure, the drain valve 100 can realize the automatic driving of the valve core 120 while maintaining the original functions of the drain valve 100, eliminating the need for manual operation and being convenient to use.

[0055] Furthermore, the execution components of this automatic driving unit 200 are installed in the valve case 110 and are located above the valve core 120. On the one hand, the drain valve 100 can realize automatic drainage by increasing the occupied space. On the other hand, since the transmission distance between the execution components and the valve core 120 is short, there is an advantage of high transmission efficiency.

[0056] Furthermore, when attaching the automatic drive unit 200 to the drain valve 100, it is only necessary to directly install it between the slider 130 and the valve core 120, and there is no need to improve other structures of the drain valve 100. Even after long-term use or if a component fails, it is only necessary to repair or replace the corresponding component, without affecting other components. Also, since the drain valve 100 retains its original function, even if the automatic drive unit 200 fails, it does not affect the normal drainage of the toilet.

[0057] Therefore, when this automatic drive unit 200 provided in this embodiment is applied to a toilet, it has the advantages of improving the convenience of using the toilet, having good use stability, and low repair costs.

[0058] The following describes examples of specific embodiments of the automatic drive unit 200:

[0059] Example 1:

[0060] As shown in FIGS. 1a - 3b, the fixed component has a case 212, the case 212 is fitted into the valve case 110 and fixed to the inner wall surface of the valve case 110. The movable component is a piston fitted inside the case 212, and one end of the piston protrudes from the case 212 and is fixedly connected to one end of the valve core 120.

[0061] In one embodiment of this example, as shown in FIGS. 1a-1b, the driving component has a pressure adjusting component 211, the case 212 is a sealed case, and a sealed cavity is formed inside. The piston has a piston body 214 and a piston rod 213, and the piston body 214 is slidably connected within the sealed cavity. The case 212 forms a through hole at one end close to the valve core 120. One end of the piston rod 213 is fixedly connected to the piston body 214, and the other end is fixedly connected to the valve core 120 through the through hole. The outer wall surface of the piston rod 213 is sealingly connected to the inner wall surface of the through hole. The pressure adjusting component 211 is connected to the sealed cavity through a pressure pipeline that penetrates the side walls of the valve case 110 and the case 212.

[0062] In this solution, the pressure adjusting component 211 is set as a hydraulic pump or an air pump.

[0063] Specifically, since the movable component directly moves the valve core 120 to open and close the drain valve 100, the transmission path is short. When the automatic driving unit 200 is attached to the drain valve 100, the transmission efficiency between the automatic driving unit 200 and the valve core 120 of the drain valve 100 can be improved.

[0064] More specifically, the side close to the valve core 120 inside the case 212 is a positive pressure chamber. A first connection hole 215 is provided on the side wall of the case 212 close to the valve core 120. The positive pressure chamber inside the case 212 is connected to the hydraulic pump or the air pump through the first connection hole 215 via a pressure pipeline.

[0065] In another embodiment of this example, as shown in FIGS. 2a-2b, the fixed component has an electromagnetic component 221 installed in the case 212, the movable component is a magnetic induction component 222 installed opposite to the electromagnetic component 221, and the driving component is a power source 223. One of the electromagnetic component 221 and the magnetic induction component 222 is fixedly connected in the case 212, and the other is movably installed in the case 212. It is located between the electromagnetic component 221 and the valve core 120 and is fixedly connected to the valve core 120.

[0066] In this solution, the movement of the movable component is realized by using the repulsive force between the electromagnetic component 221 and the magnetic induction component 222. Thereby, it is not necessary to set the driving component individually, and the structure becomes simpler. This is advantageous for further simplifying the structure of the drain valve 100 adopting the automatic driving unit 200 and reducing its installation cost.

[0067] Preferably, in this solution, the electromagnetic component 221 is set as an electromagnet, and the magnetic induction component 222 is set as a permanent magnet or a metal block. The electromagnetic component 221 is fixedly connected in the case 212, the magnetic induction component 222 is movably installed in the case 212, is located on the side away from the valve core 120 from the electromagnetic component 221, and is fixedly connected to the valve core 120.

[0068] Specifically, in this embodiment, the electromagnetic member 221 is fixedly connected to the side wall surface close to the valve core 120 in the housing 212, and the magnetic induction member 222 is movably arranged on the side away from the valve core 120 of the electromagnetic member 221 inside the housing 212.

[0069] In another embodiment of this example, as shown in FIGS. 3a-3b, the fixed component further has a gear 231 installed in the case 212, the movable component is a rack 232 that meshes with the gear 231 and extends along the axial direction of the valve case 110, and the driving component is a motor 233. A guide seat is provided on the inner wall of the valve case 110. The rack 232 is slidably connected to the guide seat. The gear 231 is fixedly connected to the output shaft of the motor 233, and one end of the rack 232 is fixedly connected to the valve core 120.

[0070] In this solution, the transmission between the gear 231 and the rack 232 is adopted. On the other hand, the gear 231 and the rack 232 are not affected by external pressure under any circumstances, and their performance is more stable when installed in the valve case 110. In addition, the tooth transmission between the gear 231 and the rack 232 has the advantage of high transmission accuracy. When the valve core 120 is interlocked by using the transmission structure of the gear 231 and the rack 232, the moving displacement of the valve core 120 becomes more accurate, thereby enabling accurate control of the drainage volume of the toilet and helping to save water resources.

[0071] Embodiment 2:

[0072] As shown in FIGS. 4a-6b, the fixed component has a case 212, the case 212 is fitted into the valve case 110 and fixed to the inner wall surface of the valve case 110. The movable component is a piston fitted inside the case 212, one end of the piston protrudes from the case 212, and the inner end of the slider 130 is fixedly connected to the other end away from the valve core 120.

[0073] In this embodiment, the movable component drives the slider 130, and the valve core 120 is opened and closed by using the existing transmission method between the slider 130 and the valve core 120, so that automatic drive can be realized without changing the transmission principle of the existing drain valve 100. This has a simple structure and a simpler transmission principle.

[0074] Specifically, in one embodiment of this example, as shown in FIGS. 4a-4b, the driving component includes a pressure adjusting component 211, the case 212 is a sealed case, and a sealed cavity is formed inside. The piston includes a piston body 214 and a piston rod 213. The piston body 214 can be slidably connected relative to the sealed cavity. The case 212 forms a through hole at the other end away from the slider 130. One end of the piston rod 213 is fixedly connected to the piston body 214, the other end is fixedly connected to the inner end of the slider 130 through the through hole, and the outer wall surface of the piston rod 213 is sealingly connected to the inner wall surface of the through hole. The pressure adjusting component 211 is connected through a pressure pipeline that penetrates the sealed cavity, the valve case 110, and the side wall of the case 212.

[0075] In this solution, by setting the case 212 as a sealed case, when the case 212 is installed in the valve case 110, since the case 212 has a sealed structure, the water pressure in the valve case 110 will not interfere with the normal operation of the executing component. Also, by adopting the pressure adjusting component 211 as the driving component, the pressure transmission has the advantage of easy layout. By adopting this solution, the automatic driving unit 200 can be conveniently integrated with the toilet drain valve 100.

[0076] Specifically, in this solution, the pressure adjusting component 211 can be set as a hydraulic pump or an air pump.

[0077] More specifically, the side close to the valve core 120 in the case 212 is set as a positive pressure chamber, and a second connection hole 216 is provided on the side of the case 212 close to the slider 130. The positive pressure chamber in the case 212 is connected to the hydraulic pump or the air pump through the second connection hole 216 via a pressure pipeline.

[0078] In another embodiment of this example, as shown in FIGS. 5a - 5b, the fixed component further includes an electromagnetic component 221 installed within the case 212, the movable component is a magnetic induction component 222 installed opposite to the electromagnetic component 221, and the driving component is a power source 223. When one end of the piston protrudes from the case 212 and the inner end of the slider 130 is fixedly connected to the other end away from the valve core 120, one of the electromagnetic component 221 and the magnetic induction component 222 is fixedly connected within the case 212, the other one is movably installed within the case 212, is located between the electromagnetic component 221 and the slider 130, and is fixedly connected to the slider 130.

[0079] Similarly, in this embodiment, in order to realize the movement of the movable member by utilizing the repulsive force between the electromagnetic member 221 and the magnetic induction member 222, there is no need to provide a separate drive, the structure becomes simpler, and it contributes to further simplifying the structure of the drain valve 100 using the automatic drive unit 200 and reducing the retrofitting cost.

[0080] Specifically, since the electromagnetic member 221 is an active magnetic force control member, in this embodiment, it is preferably fixedly connected to the inside of the housing 212 in the same way, and the magnetic induction member 222 is movably provided inside the housing 212 so as to be fixedly connected to the valve core 120 and be interposed between the electromagnetic member 221 and the valve core 120.

[0081] Furthermore, according to a preferred embodiment, the specific structures of the electromagnetic member 221 and the magnetic induction member 222 are similar to those in Embodiment 1. The description is omitted in this embodiment.

[0082] Furthermore, according to a preferred embodiment, the electromagnetic member 221 is fixedly connected to the side wall surface close to the slider 130 within the housing 212, and the magnetic induction member 222 is movably arranged on the side away from the slider 130 of the electromagnetic member 221 inside the housing 212.

[0083] In another embodiment based on this embodiment, as shown in FIGS. 6a-6b, the fixed member includes a gear 231 provided in the housing 212, the movable member is a rack 232 that meshes with the gear 231 and extends in the axial direction of the valve box 110, the driving member is a motor 233, and a guide base is provided on the inner wall of the valve box 110. The rack 232 is slidably connected to the guide base, the gear 231 is fixedly connected to the output shaft of the motor 233, and the other end of the rack 232 is fixedly connected to the slider 130.

[0084] In this embodiment, the transmission between the gear 231 and the rack 232 is adopted. Similarly, it contributes to improving the stability when the automatic driving unit 200 is installed in the valve box 110, and can accurately control the drainage volume of the toilet, contributing to water conservation.

[0085] In a more preferred embodiment based on Embodiment 1 and Embodiment 2, the housing 212 is a closed housing, and both the electromagnetic member 221 and the magnetic induction member 222 are provided in the housing 212.

[0086] Specifically, by making the housing 212 a closed housing, the electromagnetic member 221 and the magnetic induction member 222 are independent of each other from the water in the valve box 110. When the valve core 120 moves in conjunction due to the repulsive action between the electromagnetic member 221 and the magnetic induction member 222, the water pressure in the valve box 110 does not affect the repulsive force between the electromagnetic member 221 and the magnetic induction member 222. Therefore, the solution disclosed in this embodiment can further improve the stability during the operation of the drain valve 100.

[0087] Furthermore, in a preferred embodiment based on the present invention, an automatic driving unit 200 of a toilet drain valve is disclosed, which is characterized by including an operation button (not shown) that is electrically connected to the driving member and fixed on the outer wall surface of the toilet seat. During use, by operating the operation button, the driving member actuates the actuator. With the above structure, the user can actively control the automatic driving unit 200 by operating the operation button, which has the advantage of excellent stability.

[0088] Specifically, the operation button includes a base, a switch installed on the base, and a timer component. The switch has an operation key disposed outside the base, and the switch and the timer component are electrically connected to each other. When the operation key is pressed, the timer component starts timing, and the driving component operates the executing component. When the timing of the timer component reaches the preset time threshold, the driving component returns the executing component to the initial state.

[0089] More specifically, in this embodiment, by integrating the timer component into the operation button, the automatic driving unit 200 can automatically close after opening the valve core 120 for a certain period of time. Thereby, not only the degree of automation is increased, but also the drainage volume during the toilet cleaning becomes more reasonable, and it is possible to avoid a large amount of water being wasted during the toilet cleaning.

[0090] Furthermore, in the automatic driving unit 200 of the toilet drainage valve provided by this invention, the sensing component includes a capacity sensor or a pressure sensor installed within the seat ring of the toilet seat. The operation button detects the human body information of the seat ring and generates a sensing signal.

[0091] Specifically, in this embodiment, the sensing component is set as a capacity sensor or a pressure sensor integrated on the seat ring of the toilet seat. The capacity sensor or the pressure sensor can directly detect the characteristic information of the human body and generate a sensing signal through its own structure. Since there is no need to set other signal conversion elements, its structure is simpler.

[0092] In this embodiment, the timer component can be set as a timer, and the time threshold can be set to 5 seconds. The specific value can also be set to other values, and there is no specific requirement in this embodiment.

[0093] Furthermore, in another embodiment of this invention, a toilet drain valve assembly is also provided. Specifically, as shown in Embodiment 1 and Embodiment 2 of FIGS. 1a - 6b, the drain valve assembly includes a drain valve 100 and an automatic drive unit 200 of Embodiment 1 and Embodiment 2, and at least the executing components in the automatic drive unit 200 are installed within the valve case 110 of the drain valve 100.

[0094] Specifically, in this embodiment, it is also possible to install all components (i.e., driving components and executing components) of the automatic drive unit 200 inside the tank, or only install the executing components inside the tank and install the driving components outside the tank. The specific setting is determined by the actual design. In this embodiment, in order to save the overall occupied space of the toilet, it is preferred to install all components of the automatic drive unit 200 inside the toilet tank.

[0095] Specifically, by integrating the automatic drive unit 200 into the toilet, it is possible to realize the automatic drive of the valve core 120 while maintaining the functions of the existing drain valve 100. Thereby, there is no need for manual operation by humans, and it is convenient to use. In particular, when adding the automatic drive unit 200 to the drain valve 100, it only needs to be directly installed between the slider 130 and the valve core 120, and there is no need to modify other structures of the drain valve 100. Even if a component fails after long - term use, only the corresponding component needs to be repaired or replaced, without affecting other components. Also, since the drain valve 100 retains its original functions, even if the automatic drive unit 200 fails, it does not affect the normal drainage of the toilet. Therefore, when the toilet provided by this embodiment adopts the automatic drive unit 200 of this structure, it has the advantages of improving the convenience of toilet use, good use stability, and low repair costs.

[0096] The present invention is illustrated and described with reference to some preferred embodiments of the present invention. However, as should be understood by those of ordinary skill in the art, the above content has been described in more detail in combination with specific embodiments regarding the specific embodiments of the present invention, and the specific implementation of the present invention is not limited to these descriptions. Those skilled in the art can make various changes in form and details, including making some simple inferences and substitutions, without departing from the spirit and scope of the present invention.
