Technical Field

[0001] The invention relates to the field of sanitary ware, and in particular to a flush valve controller, a water tank and a toilet. Background Art

[0002] In the bathroom field, in order to achieve the purpose of water saving, the existing toilet drain valves basically include a half-flush button, a full-flush button, a button seat, a transmission mechanism and a main body, wherein a water-sealing valve plate is arranged in the main body, and the half-flush button and the full-flush button respectively control the transmission mechanism to lift the water-sealing valve plate to different heights, thereby realizing urinary and fecal sewage discharge.

[0003] The half-flush and full-flush functions of existing automatic flush toilets are both achieved through separate driving mechanisms, i.e., one driving mechanism corresponds to the half-flush and the other driving mechanism corresponds to the full-flush. Therefore, an automatic flush toilet with half-flush and full-flush functions requires two sets of driving mechanisms, which increases the cost and also increases the space occupied by the driving mechanisms. Summary of the invention

[0004] The present invention aims to provide a flush valve controller to solve the problem that the existing automatic flush controller needs to realize two flush functions through respective independent driving mechanisms.

[0005] The specific plan is as follows:

[0008] Furthermore, the first through hole is arranged on one end portion of the first swing arm, and the second through hole is arranged on one end portion of the second swing arm.

[0009] Furthermore, the rotating shaft includes a first rotating shaft and a second rotating shaft, the first swing arm is arranged on the first rotating shaft, the second swing arm is arranged on the second rotating shaft, the first rotating shaft and the second rotating shaft are connected by a first gear transmission pair, and the rotation directions of the first rotating shaft and the second rotating shaft are opposite.

[0010] Furthermore, the first gear transmission pair includes a first gear located on the first rotating shaft and a second gear located on the second rotating shaft. When the first gear and the second gear are meshed with each other, a third idle stroke is provided between the meshed gear teeth.

[0011] Furthermore, an extension rod coaxially arranged with the rotating shaft is fixedly provided on the first swing arm or the second swing arm, and the extension rod has a connecting portion drivingly connected to a manual button of the flush valve.

[0012] Furthermore, it also includes a third rotating shaft and an angle sensor, one end of the third rotating shaft is drivingly connected to the rotating shaft through a first gear transmission pair, and the other end is connected to the angle sensor.

[0016] The flush valve controller provided by the present invention has the following advantages compared with the prior art: the first swing arm and the second swing arm of the flush valve controller provided by the present invention have idle strokes corresponding to the clockwise and counterclockwise rotation of the rotating shaft respectively, so when the rotating shaft rotates clockwise and counterclockwise, only one of the first swing arm and the second swing arm will be driven to move, so the flush valve controller can achieve drainage of both functions through only one driving member. Compared with the existing independent driving mechanisms, the flush valve controller has a simple structure, low cost, more cost advantages, and occupies a relatively small installation space.

[0026] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a flush valve controller, which includes a bracket 1 and a driving mechanism 2 installed on the bracket 1. Specifically, the driving mechanism 2 includes a driving member 20, a rotating shaft 21 drivingly connected to the driving member 20, and a first swing arm 22 and a second swing arm 23 sleeved on the rotating shaft 21. For the convenience of description, in this embodiment, the first swing arm 22 and the second swing arm 23 are respectively drivingly connected to one of the full-flush switch and the half-flush switch of the toilet, so that when the first swing arm 22 and the second swing arm 23 are in motion, the corresponding drain switch is controlled to perform a drain operation, but the flush valve controller is not limited to being used only on toilets, and can also be applied to other devices with two drain states, such as being installed on a water tank with two drain states.

[0029] The driving member 20 can drive the rotating shaft 21 to rotate clockwise and counterclockwise, and a first clutch structure is provided between the first swing arm 22 and the rotating shaft 21, and a second clutch structure is provided between the second swing arm 23 and the rotating shaft 21, wherein the first clutch structure and the second clutch structure have idle strokes corresponding to one of the clockwise rotation and counterclockwise rotation of the rotating shaft 21, respectively, so that when the rotating shaft 21 rotates clockwise and counterclockwise by a certain angle, only one of the first swing arm 22 and the second swing arm 23 is driven to move, so as to control the first swing arm 22 and the second swing arm 23 to realize the full flush and half flush of the corresponding toilet. The driving member 20 can be a device that can directly drive the rotating shaft 21 to rotate by a motor, or can be a crank-connecting rod mechanism that converts a linear reciprocating motion into a rotational motion, but from the perspective of cost and installation space, it is preferred to use a motor as the driving member, and this example also takes the driving member 20 as a motor as an example for explanation.

[0030] In this embodiment, for the convenience of description, the first clutch structure between the first swing arm 22 and the rotating shaft 21 has a first idle stroke corresponding to the counterclockwise rotation of the rotating shaft 21, and the second clutch structure between the second swing arm 23 and the rotating shaft 21 has a second idle stroke corresponding to the clockwise rotation of the rotating shaft 21, and the first swing arm 22 corresponds to the half-flush of the toilet, and the second swing arm 23 corresponds to the full-flush of the toilet. Therefore, when the driving member 20 drives the rotating shaft 21 to rotate clockwise by a certain angle, under the premise that the rotation angle does not exceed the second idle stroke of the second clutch structure, the rotating shaft 21 rotates idly corresponding to the second swing arm 23, so the rotating shaft 21 only drives the first swing arm 22 to move and realize the half-flush of the toilet; similarly, when the driving member 20 drives the rotating shaft 21 to rotate counterclockwise by a certain angle, under the premise that the rotation angle does not exceed the first idle stroke of the first clutch structure, the rotating shaft 21 rotates idly corresponding to the first swing arm 23, so the rotating shaft 21 only drives the second swing arm 23 to move and realize the full-flush of the toilet. Therefore, the flush valve controller can realize the control of half-flush and full-flush of the toilet only through one driving component. Compared with the existing independent driving mechanisms, the flush valve controller has a simple structure, low cost, more cost advantage, and occupies a relatively small installation space. In addition, the drainage volume of the drain valve of the toilet has nothing to do with the flush valve controller itself, but only with the drainage volume of the drain valve itself. Therefore, the flushing volume can be adjusted by the drain valve itself, which makes the flushing volume of the toilet more consistent and easier to control.

[0031] As a first preferred embodiment of this embodiment, refer to Figure 2The flush valve controller further includes a third rotating shaft 30 and an angle sensor 31. One end of the third rotating shaft 30 is drivingly connected to the rotating shaft 21 through a second gear transmission pair 32, and the other end is connected to the angle sensor 31. When the driving member 20 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the third rotating shaft 30 to rotate through the second gear transmission pair 32. According to the transmission ratio of the second gear transmission pair 32 and the angle sensor 31, the rotation angle of the rotating shaft 21 can be fed back in real time to control the swing angle of the first swing arm 22 and the second swing arm 23. The angle sensor in this embodiment is a rotation position sensor (model SV03A103AEA01B00) of Murata Manufacturing Co., Ltd., but is not limited thereto, and other angle sensors with the same function can be used.

[0032] As a second preferred implementation scheme of this embodiment, the first clutch structure and the second clutch structure are both through holes and protrusions that are matched with each other, wherein the through holes are arranged on the first swing arm 22 and the second swing arm 23, and the protrusions are arranged at positions of the rotating shaft 21 corresponding to the first swing arm 22 and the second swing arm 23, and the through holes have a travel space for the protrusions located in the through holes to rotate with the rotating shaft 21, and blocking parts are located on both sides of the travel space.

[0033] Specifically, refer to Figure 3 and Figure 4 The first swing arm 22 has a first through hole 220 for the rotating shaft 21 to pass through, and the rotating shaft 21 has a first protrusion 210 located in the first through hole 220. The first through hole 220 has at least one first blocking portion 221 protruding in the first through hole 220. In this embodiment, the first through hole 220 has two first blocking portions 221 disposed opposite to each other and two first protrusions 210 disposed opposite to each other as an example for explanation. The space between the two adjacent surfaces of the two first blocking portions 221 is the first idle stroke of the first protrusion 210 in the first through hole 220. If there is only one first blocking portion 221 in the first through hole 220, then the first idle stroke is the remaining space of the first through hole 220 excluding the first blocking portion 221. The first idle stroke in the first through hole 220 is the idle stroke when the rotating shaft 21 rotates counterclockwise.

[0034] When the first idle stroke is less than 180° relative to the rotation angle of the shaft 21, two first blocking portions 221 and two first protrusions 210 disposed opposite to each other can be used to make the force generated by the first blocking portion 221 on the shaft 21 relatively balanced when the shaft 21 rotates, thereby reducing the probability of the shaft 21 being damaged. If the first idle stroke is greater than or equal to 180° relative to the rotation angle of the shaft 21, the blocking portion 221 can only be biased on one side of the first through hole 220, so the force generated by the blocking portion 221 on the shaft 21 is also biased, and the shaft 21 is more likely to be damaged relative to the two first blocking portions 221 disposed opposite to each other, but the idle stroke can have a larger angle. Since the first through hole 220 in this embodiment is located at one end of the first swing arm 22, the first swing arm 22 uses the shaft 21 as a fulcrum, so the first swing arm 22 can also have a large swing amplitude when having a smaller idle stroke, so as to realize the action of the corresponding drain valve of the toilet.

[0035] Similar to the first swing arm 22, refer to Figure 5 and Figure 6 The second swing arm 23 has a second through hole 230 for the rotating shaft 21 to pass through, the rotating shaft 21 has a second protrusion 211 located in the second through hole 230, and the second through hole 230 has at least one second blocking portion 231 protruding in the second through hole 230. In this embodiment, the two second blocking portions 231 and the two second protrusions 211 disposed opposite to each other in the second through hole 230 are used as an example for explanation, and the space between the two adjacent surfaces of the two second blocking portions 231 is the second idle stroke of the second protrusion 211 in the second through hole 230. The second idle stroke in the second through hole 230 is the idle stroke when the rotating shaft 21 rotates clockwise.

[0036] refer to Figure 3-Figure 6 When the shaft 21 rotates clockwise, the first protrusion 210 on the shaft 21 drives the first swing arm 22 to lift up, realizing half flushing of the toilet drain valve, and at the same time, the second protrusion 211 on the shaft 21 is located in the second idle stroke of the second swing arm 23, so when the first swing arm 22 swings, the second swing arm 23 does not move. When the shaft 21 rotates counterclockwise, the first protrusion 210 on the shaft 21 is located in the first idle stroke of the first swing arm 22, so the first swing arm 22 does not move, and at the same time, the second protrusion 211 on the shaft 21 drives the second swing arm 23 to lift up, realizing full flushing of the toilet drain valve.

[0037] Since the rotating shaft 21 in this embodiment includes a first rotating shaft 21a and a second rotating shaft 21b, and the first rotating shaft 21a and the second rotating shaft 21b are synchronously driven by a pair of gear transmission pairs, the rotation directions of the first rotating shaft 21a and the second rotating shaft 21b are opposite, that is, when the first rotating shaft 21a rotates clockwise, the second rotating shaft 21b rotates counterclockwise, and since the first swing arm 22 is mounted on the first rotating shaft 21a and the second swing arm 23 is mounted on the second rotating shaft 21b, the first swing arm 22 and the second swing arm 23 are mounted on the second rotating shaft 21b. Figure 4 and Figure 6 The direction of the idle stroke shown in is the same.

[0038] The first clutch structure and the second clutch structure in the second preferred embodiment are simple in structure, easy to implement and easy to assemble.

[0039] As a third preferred embodiment of this embodiment, refer to Figure 2 , Figure 7 and Figure 8 The rotating shaft 21 includes a first rotating shaft 21a and a second rotating shaft 21b, and the first rotating shaft 21a and the second rotating shaft 21b are synchronously rotated through a first gear transmission pair 24, and the rotation directions of the first rotating shaft 21a and the second rotating shaft 21b are opposite. Since the rotation directions of the first rotating shaft 21a and the second rotating shaft 21b are opposite, the first idle stroke of the first swing arm 22 arranged on the first rotating shaft 21a and the second idle stroke of the second swing arm 23 arranged on the second rotating shaft 21b can be arranged in the same direction, so the first swing arm 22 and the second swing arm 23 can also be arranged in the same direction, so the volume of the flush valve controller can be reduced.

[0040] Specifically, refer to Figure 8 , wherein the first gear transmission pair 24 includes a first gear 240 located on the first rotating shaft 21a and a second gear 241 located on the second rotating shaft 21b, and the first gear 240 and the second gear 241 respectively have a plurality of first gear teeth 2400 and a second gear tooth 2410 meshing with each other. When the first gear teeth 2400 and the second gear teeth 2410 mesh with each other, the second gear teeth 2410 also have a third idle stroke in the space between the two first gear teeth 2400, that is, the first gear teeth 2400 and the second gear teeth 2410 meshing with each other are not tightly matched, but have a certain gap, and the third idle stroke can compensate for the influence caused by the error of the first idle stroke and the second idle stroke when the first swing arm 22 or the second swing arm 23 moves. For example, when the first idle stroke is a positive tolerance and the second idle stroke is a negative tolerance, if there is no third idle stroke, when the first swing arm moves, the second swing arm will swing a small amplitude, and this small amplitude may cause the corresponding full flush valve to open and cause a certain degree of water leakage, which is undesirable. The existence of the third idle stroke eliminates this phenomenon.

[0041] Preferably, reference Figure 2 The second swing arm 23 is also fixed with an extension rod 232 coaxially arranged with the second rotating shaft 21b. The extension rod 232 has a connecting portion 233 driven by a manual button of the full drain valve of the toilet. Since the second swing arm 23 has a second idle stroke cooperated with the second rotating shaft 21b, manual drainage and automatic drainage will not conflict. In the case of power failure, flushing can still be performed by manually controlling the drain valve.

[0042] As a fourth preferred embodiment of this embodiment, refer to Figure 1 and Fig. 9 The bracket 1 has a sealed chamber 10, and the electrical components of the flush valve controller are all installed in the sealed chamber 10, such as the motor as the driving member 20, the angle sensor 31, etc. are all installed in the sealed chamber 10 to prevent water vapor from affecting these electrical components, thereby affecting the service life of the flush valve controller. For example, in this embodiment, the sealed chamber 10 is located on one side of the bracket 1, and the other side opposite is a support portion 11 supporting the rotating shaft 21. The rotating shaft of the motor as the driving member 20 extends out of the sealed chamber 10 and is drivingly connected to the rotating shaft 21.

[0043] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
