[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This utility model embodiment provides an embedded inductive switch, such as Figures 1 to 4 As shown, the embedded inductive switch includes a housing 1, which has a cavity. One side of the housing 1 has an opening that passes through the cavity, and a plane lens 2 is provided at the opening. The cavity contains an inductive circuit board 3 and a top ring 4, which is tightly abutted between the inductive circuit board 3 and the plane lens 2. At least two equally spaced spring clips 5 are provided on the periphery of the side of the housing 1 away from the plane lens 2.

[0021] The embedded sensor switch in this embodiment utilizes a planar lens 2, which helps to visually integrate the product with the ceiling after installation, resulting in a seamless and aesthetically pleasing overall appearance. The top ring 4 design ensures stability between the planar lens 2 and the internal components of the product, making the product structure compact and less prone to loosening. The spring clip 5 design allows the product to be installed on ceilings of different materials, facilitating easy installation.

[0022] Specifically, in this embodiment, the sensing circuit board 3 includes a circuit board body 30 and a sensing element 31; a top ring 4 is abutted between the circuit board body 30 and the plane lens 2, and the sensing element 31 is disposed on the side of the circuit board body 30 near the plane lens 2 and corresponds to the plane lens 2, effectively ensuring the sensing range. The sensing element 31 can be, for example, an infrared sensor, suitable for scenarios such as human body sensing.

[0023] Specifically, in this embodiment, the sensing circuit board 3 further includes several terminals 32, all of which are located on the side of the circuit board body 30 away from the plane lens 2, for electrical connection of the sensing element 31 to transmit the sensing signal of the sensing element 31. Correspondingly, the housing 1 should also be provided with clearance holes corresponding to the several terminals 32 for wiring and cable routing. The clearance holes may be circular, for example.

[0024] Specifically, in this embodiment, the top ring 4 includes an integrally formed ring body 41 and several support bodies 42. The ring body 41 is hollow inside, cylindrical in shape, and adapted to the cavity, so that the sensing element 31 is enclosed within it, which helps to prevent interference to the sensing element 31. Several support bodies 42 are evenly distributed at intervals on the edge of the ring body 41 near the circuit board body 30. For example, in this embodiment, there are four support bodies 42, which are evenly distributed at intervals on the edge of the ring body 41 near the circuit board body 30, providing better support stability. The top ring 4, designed in this way, is pressed tightly between the circuit board body 30 and the plane lens 2, which can both limit the plane lens 2, improving its stability, and stabilize the circuit board body 30, thereby ensuring the stable performance of the overall switch structure.

[0025] Specifically, in this embodiment, the housing 1 includes a bottom cover 11 and a top cover 12; the top cover 12 is fastened to the bottom cover 11, and the opening is located on the side where the top cover 12 and the bottom cover 11 are fastened; a limiting groove 101 is formed between the top cover 12 and the bottom cover 11, and when the plane lens 2 is placed at the opening, its edge is inserted into the limiting groove 101 to ensure that the plane lens 2 is installed securely.

[0026] The cavity is located within the bottom cover 11, which has a cover opening 110 communicating with the cavity. A boss 111 extending radially outward is located on the outer edge of the cover opening 110, and a recess 1110 is located on the inner edge of the cover opening 110. Correspondingly, the top cover 12 is fastened to the boss 111. The top cover 12 has a clearance opening 120 corresponding to the cover opening 110. After the top cover 12 is fastened in place, the clearance opening 120 corresponds to the cover opening 110 to form an opening, and a limiting groove 101 is formed between the top cover 12 and the recess 1110. The inner diameter of the clearance opening 120 is smaller than the inner diameter of the cover opening 110, so that a mounting space for limiting and fixing the plane lens 2 can be formed between the bottom cover 11, the top cover 12, and the recess 1110. When the plane lens 2 is placed in the aforementioned mounting space, the edge of the plane lens 2 can be securely engaged in the limiting groove 101.

[0027] Specifically, in this embodiment, as Figure 5 , Figure 6 As shown, the outer periphery of the boss 111 is provided with a number of first positioning mating parts 111 distributed at equal intervals, and the cover 12 is provided with a number of second positioning mating parts 121 that are engaged with the first positioning mating parts 111 in a one-to-one manner. This facilitates direct connection between the first positioning mating parts 1111 and the second positioning mating parts 121, so that the cover 12 is stably assembled on the boss 111. The operation is simple and convenient.

[0028] Specifically, in this embodiment, the outer periphery of the housing 1 on the side away from the plane lens 2 is provided with at least two equally spaced connection ports 13, and at least two spring clips 5 are connected one-to-one with the at least two connection ports 13. For example, in this embodiment, if the outer periphery of the housing 1 on the side away from the plane lens 2 is provided with two equally spaced connection ports 13, then two spring clips 5 are also provided, so that the two spring clips 5 are connected one-to-one with the two connection ports 13.

[0029] The connection port 13, for example, consists of a groove in the bottom cover 11 and two mounting protrusions corresponding to the inner walls of the groove. The two mounting protrusions are used for the two ends of the spring portion of the spring clip 5 to be engaged accordingly. Specifically, as shown in the figure... Figure 7 , Figure 8 As shown in the diagram. It should be noted that the structure of the spring clip 5 and its connection method with the connector 13 are existing technologies. Figure 7 , Figure 8This is for illustrative purposes only and does not constitute a specific limitation. The actual application shall prevail.

[0030] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
