Detailed ways

To further illustrate the various embodiments, the present invention is provided with accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with related descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 and FIG. 2 , 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 , 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 connected with one of the full row switch and the half row switch of the toilet, so that the first swing arm 22 and the second swing arm When the swing arm 23 moves, it controls the corresponding drain switch to carry out the drain operation, but it is not limited to the flush valve controller being only used on the toilet, and can also be applied to other equipment with two drain states, such as being installed on two drain valves. on the water tank in a draining state.

Wherein, the driving member 20 can drive the rotating shaft 21 to rotate clockwise and counterclockwise, there is a first clutch structure between the first swing arm 22 and the rotating shaft 21 , and there is a second clutch structure between the second swing arm 23 and the rotating shaft 21 , wherein the first clutch structure and the second clutch structure have an idle stroke corresponding to one of the clockwise rotation and the counterclockwise rotation of the rotating shaft 21, so that when the rotating shaft 21 rotates clockwise or counterclockwise at a certain angle, only the One of the actions of the first swing arm 22 and the second swing arm 23 controls the first swing arm 22 and the second swing arm 23 respectively to realize full and half flushing of the corresponding toilet. The driving member 20 may be a device that a motor can directly drive the rotating shaft 21 to rotate, or it may be a crank linkage mechanism that converts linear reciprocating motion into rotary motion, but in consideration of cost and installation space, it is preferable to use a motor as the driving member. In this example, the driving member 20 is also taken as an example for illustration.

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 when the rotating shaft 21 rotates counterclockwise, and the first clutch structure between the second swing arm 23 and the rotating shaft 21 The second clutch structure 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-row flushing of the toilet, and the second swing arm 23 corresponds to the full-row flushing 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 rotating angle does not exceed the second idle stroke of the second clutch structure, the rotating shaft 21 idles corresponding to the second swing arm 23, so the rotating shaft 21 only drives The first swing arm 22 moves to realize half-row flushing of the toilet; similarly, when the driving member 20 drives the rotating shaft 21 to rotate a certain angle counterclockwise, under the premise that the rotation angle does not exceed the first idle stroke of the first clutch structure , the rotating shaft 21 is idling corresponding to the first swing arm 23, so the rotating shaft 21 only drives the second swing arm 23 to move so as to realize full flushing of the toilet. Therefore, the flush valve controller can realize the half-row and full-row flush control of the toilet only through one driving member. Compared with the existing independent driving mechanisms, the flush valve controller has a simple structure and low cost. It is more cost-effective, and the installation space occupied is relatively small. In addition, the drainage volume of the toilet drain valve has nothing to do with the flush valve controller itself, but only with the drainage volume of the drain valve itself, so the flushing volume can be adjusted through the drain valve itself , which makes the flush volume of the toilet more consistent and easier to control.

As the first preferred implementation of this embodiment, with reference to Fig. 2, the flush valve controller also includes a third rotating shaft 30 and an angle sensor 31, and one end of the third rotating shaft 30 is connected to the rotating shaft through a second gear transmission pair 32 21 driving connection, and the other end is connected with 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 can feed back the rotation angle of the rotating shaft 21 in real time to control the swing angles of the first swing arm 22 and the second swing arm 23 . The angle sensor in this embodiment is a rotary position sensor (model SV03A103AEA01B00) of Murata Manufacturing Co., Ltd., but it is not limited thereto, and other angle sensors with the same function can be used.

As a second preferred implementation of this embodiment, the first clutch structure and the second clutch structure are through holes and bumps that are matched with each other, wherein the through holes are set on the first swing arm 22 and the second swing arm 23 On the top, the bump is arranged on the position of the rotating shaft 21 corresponding to the first swing arm 22 and the second swing arm 23. There is a travel space for the bump in the through hole to rotate with the rotation shaft 21 in the through hole, and the travel space is located in the travel space. Barriers on both sides.

Specifically, referring to FIG. 3 and FIG. 4 , the first swing arm 22 has a first through hole 220 through which the rotating shaft 21 passes, and the rotating shaft 21 has a first protrusion 210 located in the first through hole 220 . A 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 the first blocking portion 221 disposed opposite to each other. Taking the two first bumps 210 as an example for illustration, the space between the two adjacent surfaces of the two first blocking portions 221 is the first idle travel of the first bumps 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 rotating counterclockwise relative to the rotating shaft 21

When the angle of rotation of the first idle stroke relative to the rotating shaft 21 is less than 180°, two first blocking portions 221 oppositely arranged and two first protrusions 210 arranged oppositely can be used, so that when the rotating shaft 21 rotates, the first blocking portion 221 produces a relatively balanced force on the rotating shaft 21, which can reduce the probability of the rotating shaft 21 being damaged. And if the angle of rotation of the first idle stroke relative to the rotating shaft 21 is greater than or equal to 180°, the blocking portion 221 can only be biased on one side of the first through hole 220, so the force generated by it against the rotating shaft 21 is also biased. Compared with the two opposite first blocking parts 221, the rotating shaft 21 is more likely to be damaged, but it can have a larger angle of idle travel. Since the first through hole 220 in this embodiment is located on one end of the first swing arm 22, and the first swing arm 22 uses the rotating shaft 21 as a fulcrum, the first swing arm 22 has a smaller In the case of an idle stroke, the first swing arm 22 can also have a large swing range, so as to realize the action of the toilet corresponding to the drain valve.

Similar to the first swing arm 22 , with reference to FIGS. 5 and 6 , the second swing arm 23 has a second through hole 230 through which the rotating shaft 21 passes, and the rotating shaft 21 has a second through hole 230 located in the second through hole 230 . The protruding block 211 has at least one second blocking portion 231 protruding from the second through hole 230 in the second through hole 230 . In this embodiment, the second through hole 230 has two opposite second blocking portions 231 and two oppositely disposed second bumps 211 as an example for illustration. The space is the second empty stroke of the second protrusion 211 in the second through hole 230 . The second idle stroke in the second through hole 230 is an idle stroke when rotating clockwise relative to the rotating shaft 21 .

Referring to Fig. 3-Fig. 6, when the rotating shaft 21 rotates clockwise, the first bump 210 on the rotating shaft 21 drives the first swing arm 22 to lift up to realize the half-row flushing of the toilet drain valve, and at the same time the second protrusion on the rotating shaft 21 The protrusion 211 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. And when the rotating shaft 21 rotates counterclockwise, the first protrusion 210 on the rotating 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 the second protrusion 211 on the rotating shaft 21 The second swing arm 23 is driven to be lifted to realize full row flushing of the toilet drain valve.

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 realize synchronous transmission through a pair of gear transmission pairs, the first rotating shaft 21a and the second rotating shaft 21b The direction of rotation is 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, the second swing arm 23 is mounted on the second rotating shaft 21b, so the direction of the idle travel shown in Figures 4 and 6 in the same viewing direction is the same.

The structure of the first clutch structure and the second clutch structure in the second preferred embodiment is simple, easy to implement and easy to assemble.

As the third preferred implementation of this embodiment, with reference to Fig. 2, Fig. 7 and Fig. 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 transmitted through a first gear The pair 24 realizes synchronous rotation, and makes the rotation direction of the first rotation shaft 21a and the second rotation shaft 21b opposite. Since the rotation directions of the first rotation shaft 21a and the second rotation shaft 21b are opposite, the first rotation shaft 21a arranged on the first rotation shaft 21a The first idle stroke of the swing arm 22 and the second idle stroke of the second swing arm 23 arranged on the second rotating shaft 21b can be set in the same direction, so the first swing arm 22 and the second swing arm 23 can also be set in the same direction, Therefore, the volume of the flush valve controller can be reduced.

Specifically, referring to FIG. 8 , wherein the first gear transmission pair 24 includes a first gear 240 located on the first shaft 21a and a second gear 241 located on the second shaft 21b, the first gear 240 and the second gear 241 are respectively There are a plurality of first gear teeth 2400 and second gear teeth 2410 meshing with each other. When the first gear teeth 2400 and the second gear teeth 2410 were engaged with each other, the second gear teeth 2410 also had 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 2400 engaged with each other. The second gear teeth 2410 are not closely matched, but there is a certain gap. The third idle stroke can make up for the error between the first idle stroke and the second idle stroke when the first swing arm 22 or the second swing arm 23 moves. resulting in the impact. 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, it will cause the second swing arm to swing by a small amount. This small range may cause the corresponding full-row flush valve to open and cause a certain degree of water leakage, which is undesirable. The existence of the third empty stroke eliminates the occurrence of this phenomenon.

Preferably, referring to FIG. 2 , the second swing arm 23 is also fixed with an extension rod 232 coaxially arranged with the second rotating shaft 21b, and the extension rod 232 has a connecting portion connected with the manual push button of the full drain valve of the toilet. 233. Since the second swing arm 23 has a second idle stroke set in cooperation with the second rotating shaft 21b, manual drainage and automatic drainage will not conflict, and flushing can still be performed by manually controlling the drain valve when there is no power.

As the fourth preferred implementation of this embodiment, with reference to Fig. 1 and Fig. 9, there is a sealed chamber 10 on the bracket 1, and the electrical components of the flush valve controller are all installed in the sealed chamber 10, for example as a drive The motor of the component 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 opposite side is the supporting portion 11 for supporting the rotating shaft 21, and the rotating shaft of the motor as the driving member 20 protrudes from the sealed chamber 10. It is drivingly connected with the rotating shaft 21.

Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined by the appended claims. Making various changes is within the protection scope of the present invention.
