[0002] When flushing a toilet, it is usually necessary to operate a switch device on the toilet to open a flush valve, so that the water in the water tank can enter the body of the toilet. The switch devices include knobs and buttons. Among them, the knob usually uses a helical spring to achieve reset after rotation. For example, in the patent publication number CN212506584U, the helical spring is sleeved on a rotating member. The two ends of the helical spring are respectively bent ends bent in the outer diameter direction. After the rotating spring rotates around the axis of the rotating member by a certain angle, the two bent ends are embedded at both ends of the dial block of the rotating member. Rotating the rotating member can drive the rotating member to rotate to open the flush valve and cause the helical spring to generate.

[0043] The present invention provides a knob device and a water-using device, aiming to solve the problem that the existing knobs can only be rotated clockwise or counterclockwise, resulting in inconvenient use.

[0044] Please refer to Figures 1 to 4As shown, the knob device includes a housing 1, a rotating assembly 2 and a reset assembly 3. One side of the housing 1 is used to face the rotary switch 10 and is recessed to form a mounting groove 11. A rotating hole 12 is formed through the bottom wall of the mounting groove 11. The rotating assembly 2 includes a first rotating member 21 and a second rotating member 22 disposed in the mounting groove 11. One end of the first rotating member 21 is provided with a first limiting portion 211, and the other end passes through the rotating hole 12 and is connected to the second rotating member 22 and the rotary switch 10. The bottom wall of the mounting groove 11 is limited between the first limiting portion 211 and the second rotating member 22. An abutting portion 221 is provided on the outer periphery of the second rotating member 22. The reset assembly 3 includes a pushing member 31 and an elastic member 32 disposed in the mounting groove 11. The pushing member 31 is movably connected to the wall of the mounting groove 11. One end of the pushing member 31 abuts against the abutting portion 221, and the other end abuts the elastic member 32 between the pushing member 31 and the side wall of the mounting groove 11. The abutting portion 221 is used to push the pushing member 31 when the first rotating member 21 rotates, so that the elastic member 32 is deformed.

[0045] The knob device of the present invention can be used for water-using devices provided with a rotary switch 10. The water-using device can be a toilet, a squatting pan, a faucet, etc. The rotary switch 10 can be a rotating shaft on an encoder. The knob device includes a housing 1, a rotating assembly 2 and a reset assembly 3. During assembly, the elastic member 32 and the pushing member 31 of the reset assembly 3 are sequentially installed in the mounting groove 11 of the housing 1; then the second rotating member 22 is installed in the mounting groove 11. The abutting portion 221 provided on the outer periphery of the second rotating member 22 abuts against the pushing member 31 in the mounting groove 11, so that the elastic member 32 abuts between the wall of the mounting groove 11 and the pushing block, thereby pre-pressing the elastic member 32; then the notch of the mounting groove 11 on the housing 1 faces the rotary switch 10, and the end of the first rotating member 21 away from the first limiting portion 211 passes through the rotating hole 12 of the housing 1 and is connected to the second rotating member 22 in the mounting groove 11. A recess for inserting the rotary switch 10 is formed by concaving one end of the first rotating member 21 connecting the second rotating member 22. The first rotating member 21 is connected to the rotary switch 10 through its recess, so that the first rotating member 21, the rotary switch 10 and the second rotating member 22 achieve synchronous movement. Among them, a first limiting portion 211 is provided at one end of the first rotating member 21 away from the second rotating member 22. After the first rotating member 21 is connected to the second rotating member 22, the bottom wall of the mounting groove 11 is limited between the first limiting portion 211 and the second rotating member 22, thereby preventing the first rotating member 21 and the second rotating member 22 from falling off the housing 1.

[0046] When the first rotating member 21 is rotated, the second rotating member 22 rotates accordingly through the connection with the first rotating member 21, and the abutting portion 221 of the second rotating member 22 slides with the pushing member 31, thereby pushing the pushing member 31 toward the elastic member 32, thereby compressing the elastic member 32 and increasing the elastic force of the elastic member 32. When the first rotating member 21 is released, the elastic member 32 is no longer compressed and returns to its original position, and pushes the pushing member 31 toward the second rotating member 22, and the cooperation between the pushing member 31 and the abutting portion 221 causes the rotating assembly 2 to rotate and return to its original position.

[0047] The knob device of the present invention realizes the conversion of the reciprocating movement of the pusher 31 into the rotary motion of the rotational assembly 2 by setting the cooperation between the abutment portion 221 and the pusher 31, and converting the elastic force of the elastic member 32 into the rotational torque of the rotational assembly 2, thereby realizing the bidirectional rotation and automatic reset function of the knob device, which is convenient for use. Moreover, the cooperation between the pusher 31 and the abutment portion 221 combined with the pre-pressure of the elastic member 32 enables the rotational assembly 2 to be accurately and stably reset to the initial position, maintaining the best effect.

[0048] In one embodiment, two abutment portions 221 are provided on the outer periphery of the second rotating member 22, the mounting groove 11 includes a rotating groove 111 and two slide grooves 112 respectively provided on both sides of the rotating groove 111 and both connected to the rotating groove 111, a rotating hole 12 is provided on the bottom wall of the rotating groove 111, the second rotating member 22 is provided in the rotating groove 111, the two slide grooves 112 are respectively provided in a one-to-one correspondence with the two abutment portions 221, and a reset assembly 3 is provided in each slide groove 112, and each abutment portion 221 is used to push the pusher 31 in the corresponding slide groove 112 when the first rotating member 21 rotates. The two abutment portions 221 of the second rotating member 22 are provided on both sides of the second rotating member 22, and the elastic member 32 can be a spring, so the use of double springs and double pushers 31 makes the forces on both sides of the second rotating member 22 uniform, and there will be no shaft offset, etc., and the rotating assembly 2 can be reset stably. The abutment portions 221 on both sides of the second rotating member 22 cooperate with the pushing member 31 to convert the elastic force of the elastic member 32 into the rotational torque of the rotating component 2, thereby converting the reciprocating movement of the pushing member 31 into the rotational motion of the rotating component 2, and further realizing that the knob device can be reliably automatically reset in both clockwise and counterclockwise directions.

[0049] Furthermore, please combine Figure 5 , Figure 9 , Figure 10As shown, a first groove 1121 is concavely formed in the groove side wall of the sliding groove 112 away from the rotating groove 111. A second groove 311 corresponding to the first groove 1121 is concavely formed on the side of the pushing member 31 facing the sliding groove 112. One end of the elastic member 32 is inserted into the first groove 1121 and abuts against the groove wall of the first groove 1121, and the other end is inserted into the second groove 311 and abuts against the groove wall of the second groove 311. The elastic member 32 can be a spiral compression spring. Both the first groove 1121 and the second groove 311 are grooves with a circular cross-section. The two ends of the elastic member 32 are respectively inserted into the first groove 1121 and the second groove 311, so that the elastic member 32 can be firmly fixed between the groove wall of the sliding groove 112 and the pushing member 31 without falling off.

[0050] In addition, please combine Figure 1 , Figure 9 , Figure 10 As shown, in an embodiment, a guiding groove 1122 is formed in the groove side wall of the sliding groove 112. The guiding groove 1122 extends along the direction away from the rotating groove 111. A sliding portion 312 is provided on the pushing member 31 and is inserted into the guiding groove 1122 and slidably connected to the groove wall of the guiding groove 1122. Guiding grooves 1122 are provided on both sides of the housing 1, and a sliding portion 312 is respectively provided on both sides of the pushing member 31. The pushing member 31 is located in the sliding groove 112, and the sliding portions 312 on both sides of the pushing member 31 reciprocate in the corresponding guiding grooves 1122 on both sides. When the pushing member 31 slides in the sliding groove 112, the sliding portion 312 slides in the guiding groove 1122, so that the rotating assembly 2 can not deflect both in the rotating state and the initial state. Moreover, when the rotating assembly 2 rotates, the pushing member 31 will not generate a jitter phenomenon, and the rotating device can be ensured to return to the initial state.

[0051] The sliding part 312 includes a connecting section 3121, an intermediate section 3122 and a toggle section 3123. The connecting section 3121 is formed by extending outward from the side wall of the pusher 31. The intermediate section 3122 is connected to the free end of the connecting section 3121. The intermediate section 3122 is inserted into the guide groove 1122, and the extension direction of the intermediate section 3122 is consistent with the extension direction of the guide groove 1122. The toggle section 3123 is connected to one end of the intermediate section 3122 away from the connecting section 3121 and exposed from the housing 1. For ease of assembly, the sliding part 312 can be configured as a structure with elasticity, such as configuring the sliding part 312 as a cantilever structure, wherein the connecting section 3121 of the sliding part 312 is formed by extending outward from the side wall of the pusher 31, the intermediate section 3122 is extended from the free end of the connecting section 3121 along the extension direction of the guide groove 1122, and the toggle section 3123 is connected to the free end of the intermediate section 3122. During assembly, the toggle section 3123 is toggled toward the side wall of the push member 31, so that the middle section 3122 of the sliding portion 312 is deformed, and the push member 31 is pushed into the slide groove 112 until the toggle section 3123 of the sliding portion 312 abuts against the groove wall of the slide groove 112, the toggle section 3123 is released, and the push member 31 continues to be pushed into the slide groove 112 until the middle section 3122 of the sliding portion 312 and the toggle section 3123 are inserted into the guide groove 1122. After the toggle section 3123 is inserted into the guide groove 1122, it is affected by the middle section 3122 returning to its original state and is exposed from the shell 1, so that the push member 31 is easily removed from the slide groove 112. The removal process is the reverse process of the above-mentioned assembly process, which will not be repeated here.

[0052] Furthermore, please combine Figure 5 As shown, in order to realize multiple functions, the outer circumference of the second rotating member 22 protrudes outward to form an abutting portion 221; the end of the pushing member 31 away from the elastic member 32 is concave to form a concave surface 313 that abuts against the abutting portion 221. By pre-pressing the elastic member 32 between the pushing member 31 and the groove wall of the installation groove 11, and by providing the pushing member 31 with a concave surface 313 that abuts against the abutting portion 221, the rotation assembly 2 can be stably maintained at the initial position through the cooperation between the concave surface 313 and the abutting portion 221.

[0053] In addition, please combine Figure 5 , Figure 7 and Figure 10As shown, in the above embodiment, the abutting portion 221 has a convex surface 2211 that abuts against the concave surface 313. The convex surface 2211 includes two first arc surfaces symmetrically arranged, and the two first arc surfaces are smoothly connected in a transitional manner; the concave surface 313 includes two second arc surfaces symmetrically arranged, and the two second arc surfaces are smoothly connected in a transitional manner. The second rotating member 22 utilizes the convex surface 2211 of the abutting portion 221 to cooperate with the concave surface 313 of the pushing member 31, and realizes the two-way rotation and automatic reset function of the knob device through the elastic force of the elastic member 32. The convex surface 2211 includes two first arc surfaces symmetrically arranged, and the concave surface 313 includes two second arc surfaces symmetrically arranged. Combined with the two symmetrical reset components 3, the two sides of the rotating component 2 can be evenly stressed, and situations such as the axis of rotation shifting will not occur. Moreover, the clockwise rotation stroke and the counterclockwise rotation stroke are the same. The two first arc surfaces are smoothly connected in a transitional manner, and the two second arc surfaces are smoothly connected in a transitional manner, making the abutment between the abutting portion 221 and the pushing member 31 smoother and the rotation feel better.

[0054] In one embodiment, please refer to Figures 5 to 7 As shown, a first clamping portion 212 is provided on the outer periphery of the first rotating member 21. A fixing hole 222 for inserting the first rotating member 21 is formed through the second rotating member 22. A second clamping portion 223 that is clamped with the first clamping portion 212 is provided on the hole wall of the fixing hole 222. When assembling the first rotating member 21 and the second rotating member 22, first place the second rotating member 22 in the installation groove 11 of the housing 1. The fixing hole 222 of the second rotating member 22 corresponds to the rotating hole 12 of the housing 1. Then insert the first rotating member 21 through the rotating hole 12 and into the fixing hole 222, so that the outer periphery of the first rotating member 21 abuts against the hole wall of the fixing hole 222. At the same time, the first clamping portion 212 on the first rotating member 21 and the second clamping portion 223 on the second rotating member 22 are clamped with each other. Among them, the first clamping portion 212 is a buckle, and the second clamping portion 223 is a clamping groove. In this embodiment, when the first rotating member 21 and the second rotating member 22 are installed and matched, due to the clamping relationship between the first rotating member 21 and the second rotating member 22, and the bottom wall of the installation groove 11 is limited between the first limiting portion 211 and the second rotating member 22, the first rotating member 21 and the second rotating member 22 can both be fixed on the housing 1 without falling off, and can only rotate along the axis of the hole of the main housing 1.

[0055] In another embodiment, please refer to Figure 2 、 Figure 3 、 Figure 8As shown, a second limiting portion 213 is provided on the outer periphery of the first rotating member 21. A limiting groove 13 is formed by concave inward the hole wall of the rotating hole 12, and the second limiting portion 213 is limited within the limiting groove 13. The first rotating member 21 is provided with the second limiting portion 213, which cooperates with the limiting groove 13 on the hole wall of the rotating hole 12 of the housing 1, playing a role in limiting the rotation of the first rotating member 21, and can also protect the rotary switch 10, that is, the encoder on the circuit board, so that it will not be damaged due to excessive force. Moreover, since both the second limiting portion 213 and the limiting groove 13 are single designs, it can also play an anti-misassembly effect, quickly install and position, and improve the installation efficiency.

[0056] Further, please refer to Figure 1 As shown, the rotating assembly 2 further includes a rotating housing 4. On the side of the rotating housing 4 facing the second rotating member 22, a receiving cavity 41 for receiving the first limiting portion 211 is formed by concave inward. A connecting portion for connecting with the first limiting portion 211 is provided on the cavity wall of the receiving cavity 41. To facilitate rotating the first rotating member 21, a rotating housing 4 that is convenient to grip can be provided. By providing a receiving cavity 41 on one side of the rotating housing 4, during assembly, the first limiting portion 211 of the first rotating member 21 is inserted into the receiving cavity 41, the outer periphery of the first limiting portion 211 abuts against the cavity wall of the receiving cavity 41, and the first limiting portion 211 is connected to the rotating housing 4 by screws or by snap connection, etc.

[0057] Among them, please refer to Figure 1 、 Figure 4 As shown, in an embodiment, the rotating housing 4 includes a rotating middle frame 42, a light guide ring 43, and a rotating cover 44 that are sequentially arranged in the direction away from the second rotating member 22. The rotating middle frame 42, the light guide ring 43, and the rotating cover 44 enclose the receiving cavity 41. A light source is provided in the receiving cavity 41. The rotating middle frame 42 is connected to the rotating cover 44 and clamps the light guide ring 43. A connecting portion is provided on the rotating middle frame 42. During assembly, first place the light guide ring 43 between the rotating middle frame 42 and the rotating cover 44. The rotating middle frame 42 is connected to the rotating housing 4 by screws, thereby clamping the light guide ring 43 between the rotating middle frame 42 and the rotating housing 4. Then connect the first limiting portion 211 to the connecting portion on the rotating middle frame 42 by screws, so that the first rotating member 21 is connected to the rotating middle frame 42, and thus the first rotating member 21 is connected to the rotating housing 4. Among them, the light guide ring 43 is a light-transmitting member, and a light source, such as an LED lamp, can be placed in the receiving cavity 41 to meet various lighting requirements and increase the aesthetics of the knob. It should be noted that the entire rotating housing 4 can also be set as an integrally light-transmitting member, thereby reducing the number of parts and facilitating assembly.

[0058] In addition, please refer to Figure 3 、 Figure 6 、 Figure 7As shown, in the above embodiment, a first wire passing hole 2111 is formed in the first limiting portion 211.
