Description

air sterilizer

technical field

The utility model relates to an air sterilizer.

Background technique

Ultraviolet sterilizers (cars) on the market generally only have movable and timing functions, and do not take into account the technical means for personal safety protection. Ultraviolet rays are harmful to the human body, and the human body will be harmed by ultraviolet rays if it is accidentally close to the machine when it is turned on and during the disinfection process. This is undoubtedly the major defect of existing air sterilizers. So it is necessary to modify the existing air sterilizer.

Contents of the invention

The purpose of the utility model is to provide an air sterilizer which can guarantee the safety of the human body.

In order to achieve the above object, the utility model has taken the following technical solutions:

The air sterilizer includes a frame, a timer, a lamp drive circuit and an ultraviolet lamp, and in particular, also includes a human body detector integrated with a power-on delay circuit, a delay reminder circuit and an entry delay circuit; the human body detection The device is installed on the rack and communicates with the timer and the lamp drive circuit respectively.

The utility model can realize the start-up delay start (realized by the start-up delay circuit) and the sound and light prompt function (by the delay reminder circuit) by integrating the start-up delay circuit, the delay reminder circuit and the human body detector entering the delay circuit implementation), so that personnel are informed and given sufficient time to leave the site. In addition, the human body detector will detect whether there is a person approaching during the disinfection period. When someone breaks in accidentally, it will suspend the work of the ultraviolet lamp, and restart the ultraviolet lamp after the person leaves; when someone breaks in and stays Exceeding the preset entry delay (calculated by the entry delay circuit), the human body detector will completely turn off the ultraviolet lamp, and it will continue to work only after the personnel turn it on again, so as to realize the protection of personnel.

The human body detector described above is preferably integrated with a power-on delay circuit, a delay reminder circuit and an infrared sensor detector entering the delay circuit, and the delay reminder circuit can be composed of a voice module and a speaker.

In addition, in order to protect the ultraviolet light tubes and facilitate storage, the frame may be provided with an accommodating cavity, and the ultraviolet light tubes are mounted on a light tube installed on the frame, which can bring the ultraviolet light tubes into the accommodating cavity on the stand. In this way, the ultraviolet lamp tube can be taken out from the accommodating cavity when in use, and the ultraviolet lamp tube can be hidden in the accommodating cavity after use.

A back door can also be set on the above-mentioned accommodating cavity, and a door buckle can be set on the back door to improve the protection of the ultraviolet lamp tube. And casters can be installed at the bottom of the rack to facilitate the transfer of the sterilizer.

The utility model can effectively protect personnel from being harmed by ultraviolet rays, is safe and reliable, and is convenient to use, and is suitable for disinfection of factories, offices and the like.
