Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of smart toilet accessories, specifically relating to a reset knob assembly and a smart toilet. Background Technology
[0002] Currently, some functions of smart toilets require button activation, such as bidet, feminine wash, drying, flushing, and stopping. For ease of operation, a separate control is typically provided, such as a remote control, side buttons, or a side handle. Most existing smart toilet knobs are cylindrical, which can rotate 360 degrees but lacks a reset function. Furthermore, cylindrical knobs lack a point of leverage, making them difficult to operate. Additionally, the direct connection between the cylindrical knob and the encoder via an external component makes them structurally prone to wobbling, requiring further improvement. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reset knob assembly and a smart toilet.
[0004] The present invention adopts the following technical solution:
[0005] A reset knob assembly for use on a toilet body includes a rotating bracket fixed to the toilet body, a rotating handle rotatably sleeved on the rotating bracket, a circuit board fixed to the rotating bracket, and control buttons disposed on the rotating bracket opposite to the circuit board. The circuit board is provided with a tactile switch and a plurality of Hall effect devices spaced circumferentially. It also includes a reset torsion spring sleeved in the rotating bracket. The rotating bracket includes a bracket body, a mounting post for mounting the reset torsion spring, and a limiting seat extending circumferentially from the mounting post. The rotating handle includes a sensing magnet disposed therein that triggers the Hall effect devices, and a mounting block for mounting the sensing magnet. The mounting block is located on the outer periphery of the limiting seat. The reset torsion spring is sleeved on the mounting post, with its two ends respectively abutting the two sides of the limiting seat and extending downwards to the two sides of the mounting block. Rotation of the rotating handle causes the end of the reset torsion spring opposite to the direction of rotation to rotate, providing a reset force to the rotating handle.
[0006] Furthermore, the rotating bracket also includes multiple limiting blocks circumferentially arranged on the outer periphery of the bracket body, and the inner wall of the rotating handle is provided with a limiting ring that engages with the multiple limiting blocks. The front end of the limiting block engages with the limiting ring to restrict the rotating handle from disengaging from the rotating bracket in a direction away from the toilet body.
[0007] Furthermore, the rotating bracket also includes two limiting parts symmetrically arranged in the bracket body to limit the rotation position of the rotating handle. The rotation of the rotating handle can drive the end of the reset torsion spring opposite to the rotation direction to rotate until it abuts against the relative limiting part, so that the sensing magnet triggers the relative Hall device.
[0008] Furthermore, it also includes a sealing gasket located in front of the circuit board in the rotating bracket. The sealing gasket and the opposite side of the tactile switch form an outward protrusion opposite to the tactile switch. The control button and the opposite side of the sealing gasket form an inwardly extending pressing part that can press the protrusion. The bracket body has a mounting ring for mounting the sealing gasket, and the circuit board is disposed in the mounting ring.
[0009] Furthermore, it also includes a sealing bracket for fixing the sealing gasket to the mounting ring, the sealing bracket having a clearance hole for the pressing part to pass through, and the control button being disposed on the sealing bracket opposite to the sealing gasket.
[0010] Furthermore, a first limiting member is provided between the sealing bracket and the sealing gasket. The first limiting member includes a plurality of limiting buckles provided on the opposite surfaces of the sealing gasket and the sealing bracket, and a first limiting hole provided on the sealing bracket for the relative limiting buckles to be inserted.
[0011] Furthermore, a second limiting member is provided between the control button and the sealing bracket. The second limiting member includes multiple limiting plates disposed on the opposite surfaces of the control button and the sealing bracket, and multiple second limiting holes disposed on the outer periphery of the sealing bracket that can cooperate with the multiple limiting plates. A limiting block is provided on the lower outer side of the limiting plate that can be embedded in the corresponding second limiting hole.
[0012] Furthermore, a fixing member is provided between the sealing bracket and the rotating bracket. The front end of the bracket body is formed with an installation hole for the sealing bracket to be inserted. The fixing member includes a plurality of fixing blocks circumferentially distributed on the outer periphery of the sealing bracket and a plurality of fixing holes circumferentially distributed on the inner wall of the installation hole extending outward. The fixing blocks can be inserted into the corresponding fixing holes.
[0013] Furthermore, the rotating handle includes a main body sleeved on the outer periphery of the rotating bracket and a pressing plate disposed on one side of the outer periphery of the main body.
[0014] A smart toilet includes a toilet body and a reset knob assembly as described in any of the above claims, disposed on the toilet body.
[0015] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: By defining the structure of the reset knob assembly, and through the reset torsion spring set in the rotating bracket, in conjunction with the mounting block in the rotating handle for mounting the induction magnet, when the rotating handle is rotated, the mounting block can drive the end of the reset torsion spring opposite to the rotation direction to rotate, so that the reset torsion spring is in a deformed state, providing a reset force for the rotating handle, thereby realizing the automatic reset of the rotating handle; and the function triggering of the rotating handle is achieved by using the induction magnet and the Hall device to achieve air-to-air sensing, without relying on the direct contact between the parts and the electronic parts, thus extending the life of the entire reset knob assembly.

Detailed Implementation
[0024] The present invention will be further described below through specific embodiments.
[0025] A smart toilet includes a toilet body and a reset knob assembly disposed on the toilet body.
[0026] Reference Figures 1 to 5 As shown, the reset knob assembly includes a rotating bracket 1 fixed to the toilet body, a rotating handle 2 rotatably sleeved on the rotating bracket 1, a circuit board 3 fixed to the rotating bracket 1, a control button 4 disposed on the rotating bracket 1 opposite to the circuit board 3, a reset torsion spring 5 sleeved in the rotating bracket 1, a sealing gasket 6 disposed in the rotating bracket 1 opposite to the control button 4, and a sealing bracket 7 fixing the sealing gasket 6 in the rotating bracket 1, wherein the sealing bracket 7 is located between the sealing gasket 6 and the control button 4; specifically, the circuit board 3 is provided with a tactile switch 31 opposite to the control button 4, a plurality of Hall effect devices 32 disposed circumferentially at intervals on the other side of the circuit board 3, and a plurality of indicator lights 33 disposed around the tactile switch 31 opposite to the control button 4.
[0027] The rotating bracket 1 includes a bracket body 11 connected to the toilet body, a mounting post 12 disposed in the bracket body 11 for mounting the reset torsion spring 5, a limiting seat 13 disposed in the bracket body 11 extending circumferentially around the mounting post 12, multiple limiting blocks 14 circumferentially disposed around the bracket body 11, and two limiting parts 15 symmetrically disposed in the bracket body 11 for limiting the rotation position of the rotating handle 2. Specifically, the rotating bracket 1 is made of transparent material, so that the light emitted by the multiple indicator lights 33 of the circuit board 3 is conducted through and appears as an indicator light ring.
[0028] The rotating handle 2 includes a main body 21 sleeved around the outer periphery of the bracket body 11, a pressing plate 22 disposed on one side of the outer periphery of the main body 21, a sensing magnet 23 disposed inside the main body 21 that can trigger a Hall effect device 32, a mounting block 24 disposed inside the main body 21 for mounting the sensing magnet 23, and a limiting ring 25 disposed on the inner wall of the main body 21 and engaged with multiple limiting blocks 14. The mounting block 24 is located around the outer periphery of the limiting seat 13. A reset torsion spring 5 is sleeved on the mounting post 12, with its two ends respectively abutting the two sides of the limiting seat 13 and extending radially downward to the two sides of the mounting block 24, providing a rotating mechanism. The initial position of the rotating handle 2 is calibrated and limited. When the rotating handle 2 is rotated, the end of the reset torsion spring 5 opposite to the rotation direction can rotate to abut against the relative limiting part 15, so that the induction magnet 23 triggers the relative Hall device 32. At this time, the reset torsion spring 5 is in a deformed state, providing a reset force for the rotating handle 2. Specifically, when the rotating handle 2 is sleeved on the rotating bracket 1, the front ends of multiple limiting blocks 14 are engaged with the limiting ring 25, which restricts the rotating handle 2 sleeved on the rotating bracket 1 from disengaging from the rotating bracket 1 in a direction away from the toilet body, so that the rotating handle 2 and the rotating bracket 1 fit tightly and are not easy to shake.
[0029] The sealing gasket 6 has an outwardly protruding protrusion 61 on its surface opposite to the tactile switch 31. A mounting ring 16 for mounting the sealing gasket 6 is formed in the bracket body 11, and the circuit board 3 is disposed within the mounting ring 16. Specifically, a first limiting member is provided between the sealing gasket 6 and the sealing bracket 7. The first limiting member includes multiple limiting buckles 62 disposed on the opposite surfaces of the sealing gasket 6 and the sealing bracket 7, and a first limiting hole 71 on the sealing bracket 7 into which the limiting buckles 62 can be inserted. The connection between the sealing gasket 6 and the sealing bracket 7 is achieved through the cooperation of the limiting buckles 62 and the first limiting hole 71. Furthermore, the sealing gasket 6 can be a silicone sealing gasket.
[0030] The sealing bracket 7 is detachably installed in the rotating bracket 1. The front end of the bracket body 11 has an inwardly extending mounting hole 17 for the sealing bracket 7 to be inserted. Specifically, a fixing member is provided between the sealing bracket 7 and the bracket body 11. The fixing member includes multiple fixing blocks 72 circumferentially distributed on the outer periphery of the sealing bracket 7 and multiple fixing holes 18 circumferentially distributed on the inner wall of the mounting hole 17 and extending outward. The fixing blocks 72 can be inserted into the corresponding fixing holes 18 to realize the connection between the sealing bracket 7 and the rotating bracket 1, and fix the sealing gasket 6 on the mounting ring 16 so that it is located in front of the circuit board 3 to achieve waterproof sealing of the circuit board 3.
[0031] The control button 4 is movably mounted on the sealing bracket 7. Its surface opposite the sealing gasket 6 forms an inwardly extending pressing part 41 that presses against the protrusion 61. The sealing bracket 7 has a clearance hole 73 for the pressing part 41 to pass through. When the control button 4 is pressed, it moves inward along the sealing bracket 7, causing the pressing part 41 to first press the protrusion 61, and then continue moving inward to press the touch switch 31, activating the corresponding function. When the control button 4 is released, the protrusion 61 returns to its original position, causing the control button 4 to move outward and reset. Specifically, a distance is provided between the control button 4 and the sealing bracket 7. A second limiting component is provided, which includes multiple limiting plates 42 disposed opposite to the sealing bracket 7 of the control button 4 and multiple second limiting holes 74 disposed on the outer periphery of the sealing bracket 7 and cooperating with the multiple limiting plates 42. The lower outer side of the limiting plate 42 is provided with a limiting block 421 that can be embedded in the corresponding second limiting hole 74. Through the cooperation of the limiting block 421 with the corresponding second limiting hole 74, the movement of the control button 4 is guided, and the control button 4 is prevented from dislodging from the sealing bracket 7, thus ensuring the use of the control button 4. Specifically, the multiple limiting plates 42 are arranged around the pressing part 41.
[0032] Reference Figures 6 to 7As shown, when the rotary handle 2 is rotated, the hand presses the pressing plate 22 of the rotary handle 2, causing it to rotate clockwise or counterclockwise until the reset torsion spring 5 abuts against the limiting part 15 opposite to the rotation direction. At this time, the sensing magnet 23 triggers the corresponding Hall device 32 to realize the corresponding function. During the rotation of the rotary handle 2, the mounting block 24 will drive the end of the reset torsion spring 5 opposite to the rotation direction to rotate until it abuts against the limiting part 15, so that the reset torsion spring 5 is in a deformed state, providing a reset force for the rotary handle 2. When the hand releases the pressing plate 22, the rotary handle 2 rotates in the opposite direction to reset under the action of the reset torsion spring 5, realizing the reset of the rotary handle 2.
[0033] This application defines the structure of the reset knob assembly. By using the reset torsion spring 5 set in the rotating bracket 1, in conjunction with the mounting block 24 in the rotating handle 2 for mounting the induction magnet 23, when the rotating handle 2 is rotated, the mounting block 24 can drive the end of the reset torsion spring 5 opposite to the rotation direction to rotate, so that the reset torsion spring 5 is in a deformed state, providing a reset force for the rotating handle 2, thereby realizing the automatic reset of the rotating handle 2. Moreover, the function triggering of the rotating handle 2 is achieved by using the induction magnet 23 and the Hall device 32 for air-to-air sensing, without relying on direct contact between the parts and electronic parts, thus extending the life of the entire reset knob assembly.
[0034] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
