Description

Technical Field

[0001] The utility model belongs to the technical field of infrared switches, and particularly relates to an infrared switch which is convenient to maintain. Background Art

[0002] Infrared switch is an automatic control switch realized by infrared sensing technology. It mainly realizes the automatic control function by sensing the infrared heat emitted by the outside world. It can quickly turn on various electrical equipment such as lamps, automatic doors, burglar alarms, etc. Infrared switches include human body sensing switches, human body sensing lamps, microwave sensing switches, microwave sensing lamps, wireless remote control switches, etc. Among them, the full name of infrared sensing switch is pyroelectric infrared sensing switch. It is an automatic control switch based on passive infrared sensing technology. The main sensing device is the human body pyroelectric infrared sensor. When a person enters the sensing range, the pyroelectric infrared sensor detects the change of the infrared spectrum of the human body and automatically connects the load. If the person does not leave the sensing range, it will continue to be connected; after the person leaves, the load will be automatically turned off after a delay. This switch has the characteristics of small size, simple use, stable performance, long life, fast response speed, and strong impact and anti-interference capabilities.

[0003] Publication number "CN214675112U" is an infrared switch sensor with waterproof function for weak current, which relates to the field of infrared switch technology, in order to solve the problem that the existing infrared sensing switch in the prior art is easily interfered by various external environments, such as when the infrared switch is used in an outdoor environment, after rainwater adheres to the surface of the infrared lens, it will cause the switch to fail for a short time. A shell cover is arranged on the top of the outer shell, and the shell cover is rotatably connected to the outer shell through an internal thread, an infrared sensing lens is arranged on the inner side of the shell cover, and the infrared sensing lens is arranged as an arc structure, a collection shaft is arranged at the bottom of the outer shell, and the collection shaft and the outer shell are arranged as an integrated structure, a rubber seal is arranged below the collection shaft, and the rubber seal is connected to the collection shaft through a slot, a power harness is arranged inside the rubber seal, and there are two power harnesses.

[0004] Although the above-mentioned utility model can prevent rainwater from accumulating inside the shell, the infrared switch shell is designed to be relatively closed, and specific skills or tools are required during the disassembly and assembly process. Once a failure occurs, it is usually necessary for professionals to disassemble and repair it, which increases the difficulty and cost of maintenance. At the same time, it is not convenient for daily cleaning and maintenance. If regular maintenance is not performed in time, the infrared switch may cause performance degradation due to the accumulation of dust, dirt or other contaminants, and the infrared sensor may become insensitive, resulting in a slower response speed or inability to accurately detect infrared signals. In addition, infrared switches that have not been maintained for a long time are more likely to have aging of electronic components, loose or broken connecting lines, etc., resulting in the switch not being able to work properly.
