[0002] As a detection device, a sensor can sense and measure the information being measured, and then output a signal according to a specific pattern. Due to its unique characteristics, it is often used in lighting switches to solve the problems of high wiring costs, cumbersome construction, and inconvenience associated with conventional mechanical switches. As the concept of artificial intelligence (AI) becomes increasingly prevalent, the application of microwave / infrared sensors in the lighting field is becoming increasingly common.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1-6 As shown, the utility model provides a technical solution: an infrared microwave dual-mode open-mounted and concealed two-in-one sensor, comprising a sensor housing 1, a protective circular plate 24 being detachably connected to the left side of the sensor housing 1, a dehumidification protection mechanism 3 being arranged on the left side of the protective circular plate 24, the dehumidification protection mechanism 3 comprising a humidity sensor 31, a mounting plate 32 and a storage bin 35, the storage bin 35 being movably connected to the left side of the protective circular plate 24, the inner cavity of the storage bin 35 being filled with silica gel desiccant, a circular air permeable net 351 being fixedly mounted on the inner wall of the storage bin 35, an arc-shaped air permeable net 352 being fixedly mounted on the inner wall of the storage bin 35, and the left side of the storage bin 35 being movably connected to the left side of the protective circular plate 24. There is a closing cover 353, and a rubber plug plate 354 is fixedly connected to the right side of the closing cover 353. The rubber plug plate 354 is movably inserted into the inner cavity of the storage bin 35. The silica gel desiccant is filled into the inner cavity of the storage bin 35 in advance, and then the closing cover 353 is inserted into the storage bin 35 through the rubber plug plate 354 to lock the silica gel desiccant in the inner cavity of the storage bin 35. The air inside the storage bin 35 can communicate with the air in the inner cavity of the sensor housing 1 through the circular air permeable net 351 and the arc-shaped air permeable net 352. The silica gel desiccant can absorb moisture from the air in the inner cavity of the sensor housing 1 to ensure the safety of the internal components of the sensor housing 1.

[0024] As an implementation method in this embodiment, Figure 4 、 Figure 5 、 Figure 6 As shown, a raised cover 355 is fixedly installed on the left side of the closing cover 353, a plug-in pin 356 is fixedly connected to the outer wall of the storage bin 35, a rubber strip 358 is fixedly connected to the outer wall of the plug-in pin 356, a positioning cylinder 357 is movably sleeved on the outer wall of the rubber strip 358, and the positioning cylinder 357 is fixedly installed on the left side of the protective circular plate 24. A groove 359 is provided on the right side of the storage bin 35, and a silicone suction cup 3591 is fixedly connected to the inner wall of the groove 359. The right side of the silicone suction cup 3591 is movably connected to the left side of the protective circular plate 24. The humidity sensor 31 and the mounting plate 32 are both fixedly installed on the left side of the protective circular plate 24. The left side of the mounting plate 32 is fixedly connected to the prompt light 1 33 and the prompt light 2 34. The prompt light 1 33 and the prompt light 2 34 are both connected to the humidity sensor 31 through the electrical signal between the external controller. The humidity sensor 31 is an existing structural model and can be selected as HIH-4010. The sensor 31 is used to monitor the air humidity in the inner cavity of the sensor housing 1. When the humidity reaches a first preset value, the control prompt light 33 is lit. When the humidity reaches a second preset value, the control prompt light 34 is lit at the same time, urging the user to replace the silica gel desiccant in the inner cavity of the storage bin 35 in time. The lighting of the prompt light 33 can delay the replacement of the silica gel desiccant. When the prompt light 33 and the prompt light 34 are lit at the same time, the silica gel desiccant needs to be replaced immediately. Through the connection relationship design of the positioning cylinder 357 and the plug-in pin 356, the storage bin 35 can be positioned on the protective circular plate 24 by plugging. Through the design of the rubber strip 358, the stability of the plug-in pin 356 inserted into the interior of the positioning cylinder 357 can be improved. After the plug-in pin 356 is fully inserted into the interior of the positioning cylinder 357, the silicone suction cup 3591 can be adsorbed on the outer surface of the protective circular plate 24, thereby improving the stability of the installation of the storage bin 35.

[0025] As an implementation method in this embodiment, Figure 1 、 Figure 2 、 Figure 3As shown, a PCB assembly 22 is fixedly mounted on the inner wall of the sensor housing 1, an infrared microwave sensing element 23 is fixedly connected to the left side of the PCB assembly 22, a protective cover 2 is detachably connected to the outer wall of the protective circular plate 24, a lens 21 is fixedly mounted on the inner wall of the protective cover 2, a spring clip 26 is detachably connected to the outer wall of the sensor housing 1, a fitting bottom shell 25 is detachably connected to the right side of the sensor housing 1, a wrapping bottom shell 27 is detachably connected to the right side of the sensor housing 1, a mounting tube 28 is fixedly mounted on the inner wall of the wrapping bottom shell 27, and the protective cover 2 is mounted on the protective circular plate 24 by a rotating snap connection, which is convenient for users to disassemble and assemble the protective cover 2. Users can selectively install the fitting bottom shell 25, the spring clip 26 or the wrapping bottom shell 27 and the mounting tube 28 on the sensor housing 1. Through the design of the spring clip 26, the sensor housing 1 can be embedded and concealed, and through the design of the mounting tube 28, the sensor housing 1 can be exposed and processed, which is convenient for the use of this structure in different environments.

[0026] Working principle: When the object to be measured enters the detection range of this structure, the infrared microwave sensing element 23 can sense and measure the measured information, and output the received information as a signal according to a certain rule. The silica gel desiccant is pre-filled into the inner cavity of the storage bin 35. The silica gel desiccant can pass through the circular air permeable mesh 351 and the arc-shaped air permeable mesh 352 to absorb moisture from the air in the inner cavity of the sensor housing 1, thereby completing the dehumidification protection treatment of the internal components of the sensor housing 1.
