Description

Technical Field

[0001] The utility model relates to the field of infrared switches, in particular to an embedded infrared switch. Background Art

[0002] The full name of infrared switch is pyroelectric infrared induction switch. Any object in nature, as long as the temperature is higher than absolute zero, will always emit infrared radiation. The higher the temperature of the object, the smaller the peak wavelength of the infrared radiation it emits, and the greater the energy of the infrared radiation emitted. When a person enters the sensing range, the pyroelectric infrared sensor detects the change in the infrared spectrum of the human body and automatically turns on the load. The load will continue to be turned on as long as the person does not leave the sensing range. After the person leaves, the load will be automatically turned off with a delay.

[0003] According to a Chinese patent with the publication number of "CN219780119U", an embedded infrared control switch is disclosed, which belongs to the technical field of electrical housings, including a sensing bottom shell, the inner surface wall of the sensing bottom shell is provided with a plurality of bosses, a sensing top shell, the outer surface of the sensing top shell is provided with a plurality of recesses, and a connecting mechanism, the connecting mechanism includes a plurality of groups of fixing plates, each group of fixing plates is provided with two, each group of two fixing plates are fixedly connected to the inner surface wall of the sensing top shell, the sensing bottom shell is used to be installed inside a preset groove of the wall, the bosses on the sensing bottom shell and the recesses on the sensing top shell cooperate, so that the connection between the sensing bottom shell and the sensing top shell is more stable, avoiding shaking when they are connected, the rotation of the installation shaft can drive the transmission gear to rotate, the transmission gear and the corresponding locking gear rod are meshed, and the locking gear rod is driven to slide between the corresponding two fixing plates, when the locking gear rod passes through the locking holes on the sensing bottom shell and the sensing top shell at the same time, the sensing bottom shell and the sensing top shell are locked, which is convenient for installation and disassembly;

[0004] It can be known from the above structure that the above device can drive the transmission gear to rotate by rotating the installation shaft, and the transmission gear and the corresponding locking gear rod are meshed, driving the locking gear rod to slide between the corresponding two fixed plates. When the locking gear rod passes through the locking holes on the sensing bottom shell and the sensing top shell at the same time, the sensing bottom shell and the sensing top shell are locked, which is convenient for installation and disassembly. However, when installing the sensing top shell through this installation method, multiple installation shafts need to be rotated to achieve the installation positioning effect, thereby reducing the efficiency of device installation when rotating multiple installation shafts, and when installing the circuit board, it relies on clamping by the splint, resulting in low stability, which in turn reduces the accuracy of the infrared switch.
