[0030] Reference Figures 1-7 As shown, an electric switch is proposed in an embodiment of the present utility model, which includes a housing 1, an operating member 2, a circuit board 5, a rotation monitoring assembly 3 and a pull-press monitoring assembly 4. The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are connected and enclosed to form an accommodating space by means including but not limited to bolt connection and snap connection. The circuit board 5 is disposed in the accommodating space and fixed to the lower housing 12. The operating member 2 includes an operating member body 22 and a connecting shaft 21. The operating member body 22 is located outside the housing 1 and is rotatably connected to the housing 1 through the connecting shaft 21. The connecting shaft 21 is inserted into the accommodating space from the upper housing 11. It can be understood that the operating member body 22 and the connecting shaft 21 can be either fixedly connected or rotatably connected, that is, the connecting shaft 21 can be circumferentially limited in the housing 1 or can rotate relative to the housing 1 about its own axis. At the same time, the operating member 2 can also perform a pressing movement relative to the housing 1 (hereinafter referred to as a pressing movement) or a pulling movement relative to the housing 1 (hereinafter referred to as a pulling movement) along the length direction of the connecting shaft 21. The rotation monitoring assembly 3 and the pull-press monitoring assembly 4 are both electrically connected to the circuit board 5. The rotation monitoring assembly 3 is used to monitor the rotational movement of the operating member 2. The rotation monitoring assembly 3 can generate a rotation signal when the operating member 2 performs a rotational movement. The pull-press monitoring assembly 4 includes a first Hall element 41 and a first magnetic member. The first Hall element 41 is a horizontal Hall element fixedly disposed on the circuit board 5. The first magnetic member is fixed relative to the operating member 2. When the operating member 2 moves relative to the housing 1, the first magnetic member can move together with the operating member 2. The first Hall element 41 can at least generate a pulling signal in response to the first magnetic member when the operating member 2 performs a pulling movement.

[0031] In the above-mentioned electric switch, the operating member body 22 can rotate relative to the housing 1, and can also perform a pulling or pressing movement relative to the housing 1. Moreover, the rotation monitoring component 3 can generate a rotation signal when the operating member body 22 rotates, and the pulling and pressing monitoring component 4 can generate a pressing signal and a pulling signal respectively when the operating member body 22 performs a pressing movement and a pulling movement. That is, the above-mentioned electric switch has at least three different input methods, which can meet the control requirements of the diversified functions of intelligent appliances and is beneficial to the integration of intelligent appliances. Moreover, the first Hall element 41 and the first magnetic member that cooperate with each other are used as the monitoring structure for generating the pulling signal, and the structure is simple.

[0032] In one of the embodiments, the first Hall element 41 can generate a pulling signal in response to the first magnetic member when the operating member 2 performs a pulling movement, and can also generate a pressing signal in response to the first magnetic member when the operating member 2 performs a pressing movement. That is, the first Hall element 41 plays the role of monitoring both the pressing movement and the pulling movement in cooperation with the first magnetic member.

[0033] Specifically, referring to Figure 3 and Figure 4 As shown, the first Hall element 41 is disposed opposite to the connecting shaft 21 along the length direction of the connecting shaft 21. The first magnetic member is disposed at one end of the connecting shaft 21 inserted into the accommodating space, or at least one end of the connecting shaft 21 inserted into the accommodating space is made of a magnetic material. That is, the connecting shaft 21 can trigger the first Hall element 41 as the first magnetic member. At this time, the distance between the first magnetic member and the first Hall element 41 is relatively close, and the generated pulling signal and pressing signal are obvious.

[0034] In other embodiments, the pulling and pressing monitoring component 4 includes a pressing sensing member disposed on the circuit board 5 and electrically connected to the circuit board 5. The pressing sensing member is disposed opposite to the connecting shaft 21 along the length direction of the connecting shaft 21. When the operating member 2 performs a pressing movement, the pressing sensing member can be triggered by the connecting shaft 21 to form a pressing signal. Specifically, the pressing sensing member can be, but is not limited to, a micro switch, a distance sensor, etc. Based on the fact that the first Hall element 41 is disposed opposite along the length direction of the connecting shaft 21, the pressing sensing member is installed on the side of the first Hall element 41 facing the connecting shaft 21.

[0035] Referring to Figure 2 and Figure 3 As shown, a through hole for the connecting shaft 21 to pass through is formed in the upper housing 11, and the connecting shaft 21 is inserted into the accommodating space through the through hole. In order to limit the movement of the operating member 2 along the length direction of the connecting shaft 21, the operating member 2 further includes a limiting member 23 disposed on the connecting shaft 21 and located in the accommodating space. The limiting member 23 can abut against the upper housing 11 when the operating member 2 performs a pulling movement, thereby preventing the operating member 2 from detaching from the housing 1.

[0036] In one embodiment, the limiting member 23 is a limiting ring sleeved on the connecting shaft 21, and the outer diameter of the limiting ring is greater than the inner diameter of the through hole through which the connecting shaft 21 passes. Specifically, an annular limiting groove is provided at one end of the connecting shaft 21 inserted into the accommodating space, and the limiting ring is snap-fitted with the connecting shaft 21 through the limiting groove. In order to reduce the assembly difficulty between the limiting ring and the connecting shaft 21, the limiting ring is an open ring and has elasticity.

[0037] In one embodiment, the rotation monitoring assembly 3 includes a second Hall element 31 fixedly arranged on the circuit board 5 and a second magnetic member 32 eccentrically arranged on the operating member body 22. The second Hall element 31 is a vertical Hall element, and the second Hall element 31 can generate a rotation signal in response to the second magnetic member 32 when the operating member 2 rotates. In order to be able to distinguish between the clockwise and counterclockwise rotations of the operating member 2 to further increase the input mode of the electric switch, at least two of the second Hall element 31 and / or the second magnetic member 32 are provided.

[0038] For example, two second Hall elements 31 are provided and one second magnetic member 32 is provided. The two second Hall elements 31 are circumferentially spaced apart on the circuit board 5. When the second magnetic member 32 rotates clockwise with the operating member 2, one second Hall element 31 can generate a clockwise rotation signal. When the second magnetic member 32 rotates counterclockwise with the operating member 2, the other second Hall element 31 can generate a counterclockwise rotation signal; or one second Hall element 31 is provided and two second magnetic members 32 are provided. When the second magnetic member 32 rotates clockwise with the operating member 2, the second Hall element 31 generates a clockwise rotation signal. When the second magnetic member 32 rotates counterclockwise with the operating member 2, the second Hall element 31 generates a counterclockwise rotation signal; or, two second Hall elements 31 and two second magnetic members 32 are provided. The two second magnetic members 32 rotate with the operating member 2 and respectively approach the two second Hall elements 31, so as to respectively form a clockwise rotation signal or a counterclockwise rotation signal in the two second Hall elements 31.

[0039] Reference Figure 5 and Figure 6 As shown in the figure, the upper housing 11 is provided in a T shape, and a first accommodating groove 111 is formed in the upper housing. The first accommodating groove 111 has an opening facing the circuit board 5, that is, the first accommodating groove 111 communicates with the accommodating space, and the second Hall element 31 is placed in the first accommodating groove 111.

[0040] Reference Figure 7As shown, the operating member body 22 is arranged in a groove-shaped structure with an opening facing one side of the housing 1 to cover the upper housing 11 therein, thereby improving the aesthetics of the electric switch. A second receiving groove 221 is formed on the side of the operating member body 22 facing the housing 1, and the second magnetic member 32 is placed in the second receiving groove 221. Specifically, a protruding portion is provided on the side of the operating member body 22 facing the housing 1, and the second receiving groove 221 is formed on the protruding portion.

[0041] More specifically, limiting protrusions are further provided on the inner wall of the second receiving groove 221. A plurality of limiting protrusions are arranged at intervals along the circumferential direction of the second receiving groove 221. After the second magnetic member 32 is placed in the second receiving groove 221, it is in interference fit with the operating member body 22 under the action of the limiting protrusions, improving the connection stability between the second magnetic member 32 and the operating member 2.

[0042] It should be emphasized that when the first magnetic member is eccentrically arranged on the operating member 2, it can also trigger the second Hall element 31 as the second magnetic member 32.

[0043] It should be noted that the horizontal Hall element has a flat form, which is arranged parallel to the surface of the circuit board 5 and is sensitive to the magnetic field running perpendicular to the surface of the circuit board 5, that is, sensitive to the pressing and pulling movements along the axis in the length direction of the connection shaft 21. The vertical Hall element is sensitive to the magnetic field running parallel to the surface of the circuit board 5, that is, sensitive to the rotational movement. Therefore, the signals formed by the first Hall element 41 and the second Hall element 31 respectively using the horizontal Hall element and the vertical Hall element are obvious.

[0044] In other embodiments, the rotation monitoring assembly 3 includes an encoder. The structure and principle of the encoder belong to the prior art and will not be elaborated here.

[0045] In one embodiment, the above four signal input methods can also be combined with each other to form more control signals, further increasing the controllable circuits. Moreover, the pulling signal and the pressing signal can also be subdivided into various different signals according to the operation time or the number of operations. For example, the pulling signal can be divided into a single-pull signal and a double-pull signal according to the specific number of pulling operations, and according to the length of the pulling operation time, the first Hall element 41 can also form a long-pull signal. Similarly, the pressing signal can be divided into a single-press signal, a double-press signal, a long-press signal, etc.

[0046] In order to enable the operating member 2 to return to the initial position after rotation or pulling / pressing and improve the repeatability of operation, the electric switch further includes a reset member 6, and the reset member 6 makes the operating member 2 maintain a tendency to return to the initial position.

[0047] In one embodiment, based on the arrangement of two second magnetic members 32, the reset member 6 includes two third magnetic members. The two third magnetic members are disposed on the side of the housing 1 facing the operating member 2. One of the second magnetic members 32 is magnetically attracted to one of the third magnetic members NS, and the other second magnetic member 32 is magnetically attracted to the other third magnetic member NS. That is, the two second magnetic members 32 and the two third magnetic members form a magnetic levitation structure, which can keep the operating member 2 tending to the initial position.

[0048] To mount the third magnetic member on the housing 1, refer to Figure 5 As shown, the upper housing 11 is further provided with a third receiving groove 112. The third receiving groove 112 has an opening facing the operating member 2, and the third magnetic member is placed in the third receiving groove 112. Since the relative positions of the first receiving groove 111 and the third receiving groove 112 in the initial position are determined, after placing the second Hall element 31 in the first receiving groove 111 and the third magnetic member in the third receiving groove 112, the initial position between the second magnetic member 32 in the second receiving groove 221 and the second Hall element 31 is determined, reducing the assembly difficulty and improving the accuracy of signal input.

[0049] Similar to the second receiving groove 221, the third receiving groove 112 is also provided with circumferentially spaced limiting protrusions, and the third magnetic member is in interference fit with the upper housing 11 through the limiting protrusions.

[0050] In another embodiment, the reset member 6 includes a volute spring. The volute spring belongs to the prior art and will not be elaborated here.

[0051] Refer to Figures 1-3 As shown, in one embodiment, the housing 1 further includes a flexible waterproof sleeve 13. The flexible waterproof sleeve 13 is made of flexible materials including but not limited to silicone. The flexible waterproof sleeve 13 is clamped between the upper housing 11 and the lower housing 12 and cooperates with the lower housing 12 to form a waterproof space. The circuit board 5, the first Hall element 41, and the second Hall element 31 are all located in the waterproof space. Specifically, sealing rings are provided on the contact surface between the flexible waterproof sleeve 13 and the upper housing 11 and on the contact surface between the flexible waterproof sleeve 13 and the lower housing 12 to improve the sealing performance of the waterproof space, thereby improving the waterproof grade of the electric switch.

[0052] Based on the arrangement of the second Hall element 31 in the first receiving groove 111, the flexible waterproof sleeve 13 is correspondingly provided with a fourth receiving groove 131 that is recessed toward the upper housing 11. The fourth receiving groove 131 is inserted into the first receiving groove 111. In addition to providing an avoidance space for the second Hall element 31, the fourth receiving groove 131 can also limit the flexible waterproof sleeve 13 and the upper housing 11 through the cooperation with the first receiving groove 111, reducing the assembly difficulty between the flexible waterproof sleeve 13 and the upper housing 11.

[0053] In one embodiment, in order to make the operating member 2 have the same feel when moving along the length direction of the connecting shaft 21, thereby improving the use comfort, the connecting shaft 21 abuts against the flexible waterproof sleeve 13. Specifically, a fifth accommodation groove 132 is provided on the side of the flexible waterproof sleeve 13 facing the connecting shaft 21, and one end of the connecting shaft 21 is inserted into the fifth accommodation groove 132 to prevent the connecting shaft 21 from detaching from the third protrusion due to the deformation of the flexible waterproof sleeve 13.

[0054] The electric switch further includes a decorative cover 7, which is fixedly arranged on the side of the operating member 2 facing away from the housing 1 and has an operation mark on its surface to improve the aesthetics of the electric switch.

[0055] In an embodiment of the present invention, an intelligent toilet is also proposed. The intelligent toilet includes a toilet body and the electric switch in any of the above embodiments. The electric switch is installed on the toilet body, and function components including but not limited to a flushing component, a heating component, a display component, etc. are arranged in the toilet body. The circuit board 5 in the electric switch is electrically connected to the above function components through a cable passing through the lower housing 12, so as to realize the control of the above function components.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
