[0037] Please refer to Figures 1, 2 and 3, Figure 1 is a schematic diagram of the structure of the waterproof button 10 in some embodiments, Figure 2 is an exploded schematic diagram of the waterproof button 10 shown in Figure 1, and Figure 3 is a cross-sectional schematic diagram of the waterproof button 10 shown in Figure 1. The waterproof button 10 provided in the present application can be used in a toilet, for example, it is arranged on the toilet seat of the toilet and serves as a flush button, heating button, spray button, etc. of the toilet. The toilet can be integrated with functional devices 1141 such as an LCD screen to achieve more functions, for example, an LCD screen is integrated to display information such as the function and status of the waterproof button 10.

[0038] In some embodiments, the waterproof button 10 includes a button seat 11, a button portion 12, a first circuit element 13, a functional component 14, and a conductive element 15. The first circuit element 13 can be a main board of the waterproof button 10, specifically a printed circuit board, which is used to realize the communication between the waterproof button 10 and an external device, such as communicating with a water spraying mechanism or a flushing mechanism of a toilet, and is also used to realize the control and power supply of the functional component 14. The button portion 12 is arranged on the button seat 11, and can reciprocate in the axial direction relative to the button seat 11 to realize the key sensing function. For example, the first circuit element 13 is arranged in the button seat 11, and the button portion 12 is formed with a contact portion 123 inserted in the button seat 11. When the user presses the button portion 12 so that the button portion 12 moves in the axial direction toward the button seat 11 until the contact portion 123 contacts the first circuit element 13, the first circuit element 13 can sense the user's key action, thereby feeding back a corresponding action signal to the external device, such as feeding back an action signal for causing the flushing mechanism to flush the toilet bowl of the toilet seat. The functional component 14 is provided at the button portion 12, and includes a functional device 1141 and a second circuit element 142 electrically connected to the functional device 1141. The functional device 1141 includes but is not limited to a liquid crystal screen, and the second circuit element 142 can be a printed circuit board electrically connected to the functional device 1141 and used to control the functional device 1141. The conductive element 15 includes but is not limited to an electrical transmission element such as a wire, and the conductive element 15 is electrically connected to the first circuit element 13 and the second circuit element 142 to achieve communication between the first circuit element 13 and the second circuit element 142.

[0039] It is understandable that the integration of the functional component 14 results in the need to set the conductive element 15 wiring between the button part 12 and the button seat 11 to realize the control and power supply of the functional component 14, and increases the openings and gaps between the button part 12 and the button seat 11. When the waterproof button 10 is used in equipment that is easily exposed to moisture, such as toilets, in order to prevent external moisture from flowing into the button seat 11 from the openings or gaps between the button part 12 and the button seat 11, or along the wiring path of the conductive element 15, causing damage to the first circuit element 13, thereby affecting the waterproof performance of the waterproof button 10. In some embodiments, the button part 12 is also formed with a wiring column 124 inserted in the button seat 11. When the button part 12 reciprocates relative to the button seat 11, the wiring column 124 reciprocates synchronously relative to the button seat 11. The wiring column 124 is provided with a wiring channel 1241 through which the conductive element 15 passes, and the wiring channel 1241 forms part of the wiring path of the conductive element 15. The waterproof button 10 also includes a waterproof element 16. The material of the waterproof element 16 includes but is not limited to rubber, plastic, or any other suitable material that can block the passage of moisture. The waterproof element 16 is disposed in the button seat 11 and is at least partially located on the side of the first circuit element 13 facing the functional component 14. The waterproof element 16 is fixedly connected to the wiring column 124.

[0040] It can be understood that when external moisture flows into the button seat 11 from between the button portion 12 and the button seat 11, the waterproof element 16 can prevent the moisture from flowing to the first circuit element 13, thereby preventing the first circuit element 13 from being damaged by moisture, and at least a portion of the waterproof element 16 can move relative to the button seat 11 with the wiring post 124. During the movement of the wiring post 124 relative to the button seat 11, no gap will be generated between the wiring post 124 and the waterproof element 16, thereby maintaining good waterproof performance during the key pressing process.

[0041] In the waterproof button 10, the conductive element 15 electrically connected to the first circuit element 13 and the second circuit element 142 extends along the wiring channel 1241 of the wiring post 124, and passes through the two ends of the wiring post 124 to be electrically connected to the first circuit element 13 and the second circuit element 142 respectively. The wiring post 124 can provide protection for the conductive element 15 to prevent the conductive element 15 from being squeezed and damaged during the relative movement of the button portion 12 and the button seat 11. At the same time, the waterproof element 16 can provide waterproofing for the first circuit element 13 to prevent external moisture from flowing into the button seat 11 from the gap between the button portion 12 and the button seat 11, such as along the wiring post 124, to damage the first circuit element 13, thereby compensating for the waterproof defects caused by the integrated functional component 14 of the waterproof button 10 and the arrangement of the wiring post 124. The arrangement of the waterproof element 16 fixedly connected to the wiring post 124 also enables at least part of the waterproof element 16 to move relative to the button seat 11 with the wiring post 124, and maintain good waterproof performance during the movement.

[0042] As shown in combination with FIG. 4 and FIG. 5 , in some embodiments, the waterproof element 16 includes a first water retaining portion 161 and a second water retaining portion 162, the second water retaining portion 162 surrounds and is connected to the periphery of the first water retaining portion 161, the first water retaining portion 161 is located on the side of the first circuit element 13 facing the functional component 14, and the second water retaining portion 162 is arranged around the first circuit element 13 along the periphery, in other words, the waterproof element 16 is covered on the first circuit element 13 and covers the side of the first circuit element 13 facing the functional component 14 and the periphery of the first circuit element 13. With such an arrangement, the waterproof element 16 can effectively block the water from between the button portion 12 and the button seat 11 from flowing to the first circuit element 13, effectively improving the waterproof performance of the waterproof button 10.

[0043] In some embodiments, the material of the waterproof element 16 includes a flexible material, for example, any suitable material such as a soft glue that can be deformed. The first water retaining portion 161 is provided with a first through hole 1611, and the wiring post 124 is penetrated by the first through hole 1611 and is interference fit with the first water retaining portion 161. In this way, the outer peripheral surface of the wiring post 124 is tightly matched with the waterproof element 16, and it is not easy for moisture to pass between the wiring post 124 and the waterproof element 16. In addition, when at least part of the waterproof element 16 moves relative to the button seat 11 with the wiring post 124, the waterproof element 16 can adapt to the deformation of other components in the button seat 11. While maintaining good waterproof performance, it is not easy to interfere with other components and cause component damage, thereby reducing the impact of the installation of the waterproof element 16 on the structure of the button seat 11.

[0044] Further, in some embodiments, the button seat 11 includes a first shell 111 and a second shell 112 connected to the first shell 111 on the side facing away from the functional component 14, and the waterproof element 16 also includes a connecting portion 163, which is connected to the periphery of the second water retaining portion 162 and is fixedly connected to the first shell 111 and the second shell 112. It can be understood that when the wiring column 124 moves relative to the button seat 11, the connecting portion 163 at the periphery of the waterproof element 16 is fixedly connected to the first shell 111 and the second shell 112, and the first water retaining portion 161 moves with the button seat 11, so that the waterproof element 16 is stretched and deformed. In this way, during the movement of the button portion 12 relative to the button seat 11, the waterproof element 16 always maintains the state of being covered by the first circuit element 13, and moisture is not easy to flow from the connecting portion 163 and the first shell 111 and the second shell 112 to the first circuit element 13, which can further improve the waterproof performance of the waterproof button 10.

[0045] In some embodiments, the second housing 112 is provided with an annular groove 1121 along the circumference, and the housing of the first housing 111 includes a main body 1111 and a clamping portion 1115, and the main body 1111 is covered with the waterproof element 16 and the first circuit element 13, and is fixedly connected to the second housing 112. The clamping portion 1115 is provided on the end surface of the main body facing the annular groove 1121, and the shape of the clamping portion 1115 is annular and adapted to the annular groove 1121. The connecting portion 163 is sleeved on the clamping portion 1115 and is pressed into the annular groove 1121 by the clamping portion 1115. In this way, the connecting portion 163 is in close contact with the clamping portion 1115 and the second housing 112 on the outer side, inner side and end surface of the clamping portion 1115, which can extend the path of water flowing from the first housing 111 and the second housing 112 into the button seat 11, and improve the sealing strength between the first housing 111 and the second housing 112, thereby improving the waterproof performance of the waterproof button 10. In some embodiments, the end surface of the body 1111 located outside the locking portion 1115 abuts against the end surface of the outer wall of the second shell 112 surrounding the annular groove 1121, and the outer circumferential surface of the body 1111 can be flush with the outer circumferential surface of the second shell 112. Such a configuration can further improve the waterproof performance between the first shell 111 and the second shell 112, and improve the appearance integrity and structural reliability of the waterproof button 10.

[0046] As shown in combination with FIG. 3, FIG. 4 and FIG. 5, in some embodiments, the first circuit element 13 is disposed on the second housing 112 and is wrapped by the waterproof element 16 between the waterproof element 16 and the second housing 112. The first circuit element 13 is provided with a second through hole 131 opposite to the first through hole 1611, the portion of the body 1111 opposite to the first water retaining portion 161 is provided with a third through hole 1112 opposite to the first through hole 1611, and the wiring post 124 is sequentially penetrated by the third through hole 1112, the first through hole 1611 and the second through hole 131. When the button portion 12 moves relative to the button seat 11, the wiring post 124 moves along the third through hole 1112, the first through hole 1611 and the second through hole 131. One end of the wiring post 124 away from the functional component 14 is located between the first circuit element 13 and the second shell 112, and the conductive element 15 passes through the end of the wiring post 124 away from the functional component 14 to connect to the first circuit element 13 between the first circuit element 13 and the second shell 112. For example, the first circuit element 13 is provided with a connection point that is arranged away from the functional component 14 for the conductive element 15 to be electrically connected. Therefore, the space formed by the first circuit element 13 and the second shell 112 can provide protection for the portion of the conductive element 15 located outside the wiring post 124. In the process of the wiring post 124 moving relative to the button seat 11, the conductive element 15 is not easily squeezed and damaged by the wiring post 124, the first circuit element 13, the waterproof element 16 and the first shell 111, which is conducive to improving the structural reliability of the waterproof button 10.

[0047] As shown in combination with FIG. 3 and FIG. 6 , in some embodiments, the button portion 12 includes a frame 121 and a wiring body 122 disposed on the frame 121, the contact portion 123 and the wiring post 124 are connected to the side of the wiring body 122 facing away from the functional component 14, and the wiring post 124 can be formed integrally with the wiring body 122. The functional device 1141 is disposed on the frame 121, and the second circuit element 142 is disposed on the side of the wiring body 122 facing away from the button seat 11 and is located between the functional device 1141 and the wiring body 122. Therefore, the functional device 1141, the frame 121 and the wiring body 122 can provide protection for the second circuit element 142, and can also prevent the second circuit element 142 from being exposed, which is conducive to improving the appearance integrity of the waterproof button 10.

[0048] In some embodiments, when the functional device 1141 is a liquid crystal screen, the frame 121 is provided with an opening facing away from the button seat 11, the functional device 1141 is sealed and connected to the end and blocks the opening, and the display surface of the functional device 1141 faces away from the second circuit element 142 to facilitate display of the function or status information of the waterproof button 10. In some embodiments, the wiring body 122 is provided with a through hole connected to the wiring channel 1241, and the conductive element 15 passes through the wiring body 122 through the through hole, and is electrically connected to the second circuit element 142 between the wiring body 122 and the second circuit element 142. Thus, the space formed by the wiring body 122 and the second circuit element 142 can provide protection for the conductive element 15. Since the conductive element 15 passes through the side of the wiring body 122 facing away from the button seat 11, during the movement of the button portion 12 relative to the button seat 11, the conductive element 15 will not be squeezed by the components on the side of the wiring body 122 facing the button seat 11, which is conducive to improving the reliability of the waterproof button 10.

[0049] In some embodiments, a limiting hole 1113 is provided at a portion of the body 1111 that is opposite to the wiring body 122, and the contact portion 123 passes through the first housing 111 through the limiting hole 1113. The contact portion 123 also passes through the waterproof element 16, and the end of the contact portion 123 is located between the waterproof element 16 and the first circuit element 13. When the button portion 12 reciprocates relative to the button seat 11, the end of the contact portion 123 can reciprocate between the first housing 111 and the first circuit element 13 to contact or detach from the first circuit element 13, thereby realizing the switch induction of the waterproof button 10. In some embodiments, the radial dimension of the end of the contact portion 123 that is used to contact the first circuit element 13 is greater than the radial dimension of the limiting hole 1113. Therefore, when the button part 12 moves relative to the button seat 11 until the end of the contact part 123 abuts the first shell 111, the first shell 111 can limit the end of the contact part 123 so that the contact part 123 will not separate from the first shell 111, thereby preventing the button part 12 from separating from the button seat 11.

[0050] In some embodiments, a reset spring may be provided at a position of the first circuit element 13 corresponding to the contact portion 123 or on the contact portion 123 to reset the button portion 12 relative to the button seat 11 after the contact portion 123 presses the first circuit element 13 to achieve key sensing.

[0051] In order to avoid the incomplete reset of the button part 12 due to the insufficient elastic reset force of the reset element such as the reset spring, which affects the normal use of the waterproof button 10, as shown in combination with FIG. 3 and FIG. 4, in some embodiments, the body 1111 is provided with a matching groove 1114 on one side facing the wiring body 122, and the button part 12 also includes a matching portion 125 connected to the wiring body 122 facing the first shell 111, and the matching portion 125 can be formed integrally with the wiring body 122. The matching portion 125 is inserted into the matching groove 1114, and when the button part 12 moves relative to the button seat 11, the matching portion 125 can reciprocate in the matching groove 1114 along the axial direction. The waterproof button 10 also includes an elastic element 17 provided in the matching groove 1114, and the elastic element 17 includes but is not limited to any suitable element with elastic recovery tendency such as rubber and spring, and the opposite sides of the elastic element 17 are respectively in contact with the bottom wall of the matching groove 1114 and the end surface of the matching portion 125. It is understandable that when the user presses the button portion 12, the matching portion 125 will squeeze the elastic element 17, so that when the user releases the button portion 12, the elastic restoring force of the elastic element 17 can tend to move the matching portion 125 in a direction away from the first housing 111 until the first housing 111 limits the contact portion 123, which is conducive to improving the reset force of the button portion 12 relative to the button seat 11, and avoiding insufficient reset force affecting the normal use of the waterproof button 10. In some embodiments, the matching portion 125 can be an annular structure, and the shape of the matching groove 1114 can be an annular structure arranged around the contact portion 123.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
