[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] This embodiment provides a push-button photoelectric induction switch, as Figures 1 to 8 shown, which includes an inner housing 3, a photoelectric induction module 4, a button 1 and an elastic member 2; an accommodation cavity 33 is formed on the inner housing 3, the photoelectric induction module 4 is arranged in the accommodation cavity 33, and the button 1 is movably covered on the accommodation cavity 33 through the elastic member 2. Pressing the button 1 triggers the switch when the button 1 approaches the photoelectric induction module 4.

[0028] In this embodiment, an accommodation cavity 33 for accommodating the photoelectric induction module 4 is formed on the inner housing 3, and the button 1 is movably covered on the accommodation cavity 33 through the elastic member 2. When the button 1 is pressed, the button 1 compresses the elastic member 2 and generates a certain movement stroke. The photoelectric induction module 4 in the accommodation cavity 33 determines whether the button 1 is pressed and thus whether the switch is triggered through the movement stroke of the button 1. The structure is simple. The user can adjust the sensitivity of the photoelectric induction module 4 to adjust the pressing stroke of the button 1, making it flexible to use.

[0029] The inner housing 3 of this embodiment is made of a light-blocking material. The accommodation cavity 33 includes the photoelectric induction module 4. The light-blocking material can effectively block external light from entering the inner housing 3, reducing or eliminating the interference of external light sources on the photoelectric induction module 4 and improving the accuracy of switch triggering. At the same time, the light-blocking material can also reduce the signal loss of the photoelectric induction module 4.

[0030] As Figure 6 and Figure 7 shown, it further includes a control board 5. The accommodation cavity 33 is cylindrical, and both axial end faces of the accommodation cavity 33 are open. The photoelectric induction module 4 is electrically connected and arranged on the control board 5. The control board 5 is arranged at the bottom of the inner housing 3 and covers the bottom surface of the accommodation cavity 33. The photoelectric induction module 4 is located in the accommodation cavity 33.

[0031] The accommodation cavity 33 of this embodiment is cylindrical, which is beneficial for production and processing. The photoelectric induction module 4 is electrically connected and arranged on the control board 5, simplifying the assembly process of the switch. The control board 5 covering the bottom surface of the accommodation cavity 33 makes the accommodation cavity 33 form a relatively closed space, which can effectively protect the photoelectric induction module 4 from the influence of the external environment and improve the stability and reliability of the switch.

[0032] Further, the photoelectric induction module 4 is a photoelectric sensor 41, and the surface of the photoelectric sensor 41 is covered with transparent glue.

[0033] In this embodiment, the photoelectric induction module 4 is a photoelectric sensor 41, which can accurately and finely measure the light change. When the button 1 is pressed to generate a light change, the photoelectric sensor 41 can quickly respond to achieve the rapid triggering of the switch. And through the photoelectric sensor 41, there is no need for physical contact, which improves the stability and reliability of the switch. In this embodiment, a protective film is formed on the surface of the photoelectric sensor 41 through transparent glue, which effectively blocks the penetration of moisture, humidity and other liquids, preventing the internal components of the sensor from being corroded, short-circuited, etc. due to moisture, thereby extending the service life of the sensor and maintaining stability and accurate triggering in a humid environment. Of course, in other embodiments, a transparent cover can also be used to cover the photoelectric sensor 41 to achieve the effect of moisture-proof sealing.

[0034] As Figures 5 to 8 shown, a stepped surface is formed on the top of the inner housing 3 on the outer periphery of the accommodation cavity 33. One end of the elastic member 2 abuts against the stepped surface, and the other end of the elastic member 2 abuts against the button 1.

[0035] The stepped surface of this embodiment plays a role in supporting and limiting the elastic member 2, so that the button 1 can maintain a stable movement trajectory during the pressing process through the elastic member 2, which helps to improve the pressing stability and pressing feel of the button 1, and has a simple structure and is convenient for installation.

[0036] As Figure 7 and Figure 8 shown, the stepped surface is annularly arranged on the outer periphery of the accommodation cavity 33. In this embodiment, the stepped surface is arranged in a ring shape, which can provide a uniform supporting force for the elastic member 2, is also beneficial to production and processing, reduces the manufacturing difficulty and cost, and improves the production efficiency. In other embodiments, the size and shape of the stepped surface can also be adjusted.

[0037] As Figure 5 and Figure 8 shown, the stepped surface includes a first stepped surface 31 and a second stepped surface 32. The first stepped surface 31 is connected to the outer peripheral wall of the accommodation cavity 33, and the height between the first stepped surface 31 and the button 1 is greater than the height between the second stepped surface 32 and the button 1. One end of the elastic member 2 of this embodiment abuts against the first stepped surface 31, and the housing wall between the first stepped surface 31 extending to the second stepped surface 32 cooperates with the outer peripheral wall of the accommodation cavity 33 to play a role in limiting the elastic member 2, so that the button 1 can maintain stability when pressed, ensuring the accurate triggering of the switch.

[0038] As Figure 8As shown, a drain groove 34 is formed on the inner housing 3. The drain groove 34 extends to the first stepped surface 31 and is in communication with the first stepped surface 31. In this embodiment, the liquid accumulated in the inner housing 3 can be discharged through the drain groove 34, effectively preventing the influence of a humid environment on internal components such as the photoelectric induction module 4 and improving the service life.

[0039] As Figures 5 to 8 shown, the elastic member 2 is a compression spring 21. One end of the compression spring 21 abuts against the first stepped surface 31, and the other end of the compression spring 21 is in contact with the button 1. The button 1 squeezes the compression spring 21 and abuts against the second stepped surface 32. In this embodiment, the compression spring 21 is used as the elastic member 2, which has a simple structure. By selecting a suitable compression spring 21, the pressing force and stroke of the button 1 can be conveniently adjusted, and the use is flexible.

[0040] As Figures 1 to 8 shown, in this example, the button 1 is circular, which is beneficial to improving the aesthetics of the button 1, but it is not limited thereto. In other embodiments, buttons 1 of other shapes can also be used. A flange 11 is provided circumferentially on the edge of the button 1. The button 1 squeezes the compression spring 21 so that the flange 11 abuts against the second stepped surface 32. By providing the flange 11, the other end of the elastic member 2 can be kept at the center position of the button 1, playing a limiting role on the other end of the elastic member 2 and preventing the button 1 from shifting relative to the elastic member 2 during the pressing process.

[0041] As Figure 1 shown, it further includes an outer housing 6. The inner housing 3 is arranged on the outer housing 6. The outer housing 6 is provided with a relief through hole at a position matching the button 1. The compression spring 21 pushes the flange 11 of the button 1 to abut against the outer housing 6 at the edge of the relief through hole. In this embodiment, when the button 1 is released, the compression spring 21 pushes the button 1 back to the initial position. Since the flange 11 is provided circumferentially on the edge of the button 1, the flange 11 abuts against the outer housing 6 at the edge of the relief through hole, ensuring the normal use of the button 1. The outer housing 6 of this embodiment can be installed on objects such as a shower handle and a toilet water tank that require an induction switch, which is convenient to use. Further, a display screen 7 is also provided on the control board 5 of this embodiment for displaying various parameters such as switch information. Correspondingly, a relief hole 8 for the display screen 7 is provided on the outer housing 6, and the user can also adjust the number of buttons 1 according to actual needs.

[0042] The use process of the present utility model is as follows:

[0043] The user first fixes the control board 5 at the bottom of the inner housing 3, ensuring that the photoelectric sensor 41 of the control board 5 is aligned with the accommodation cavity 33 of the inner housing 3. Then, the compression spring 21 is sleeved on the outer periphery of the housing wall of the accommodation cavity 33 from the top of the inner housing 3. One end of the compression spring 21 abuts against the first step surface 31, and the other end of the compression spring 21 abuts against the button 1. Then, the relief through hole of the outer housing 6 is aligned with the button 1, so that the flange 11 of the button 1 abuts against the outer housing 6 at the edge of the relief through hole, and the outer housing 6 and the inner housing 3 are fixed to form an integral body.

[0044] When the button 1 is pressed, the button 1 presses down the compression spring 21 to generate a certain movement stroke. The photoelectric induction module 4 in the accommodation cavity 33 judges that the button 1 is pressed through the movement stroke of the button 1, thereby triggering the switch. When the button 1 is released, the compression spring 21 pushes the button 1 back to the initial position, so that the flange 11 of the button 1 continuously abuts against the outer housing 6 at the edge of the relief through hole, waiting for the next press to trigger the switch.

[0045] The orientation terms mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, and therefore may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0046] The above are only the preferred embodiments of the present invention, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
