Problems solved by technology

Its shortcoming is: 1) when it is sterilizing, people must leave the room, to avoid the irradiation of ultraviolet rays, even this room is closed, in case other people stray into it by mistake; People feel inconvenience for this reason; 2) it only Disinfect and sterilize places that can be irradiated by ultraviolet rays. For some places that cannot be irradiated, such as the space at the bottom of tables, cabinets, beds and their stored items, or other air and items that are blocked by uneven walls etc., cannot be disinfected and sterilized, and the bacteria and toxins left in these places will be transmitted to humans or animals through contact with objects or air circulation, thereby causing various related diseases, so its disinfection and sterilization effects cannot be thorough. ; 4) The disinfection and sterilization effect of ultraviolet light also depends on the distance between the irradiation source and the object to be irradiated. If the distance is large, the effect will be poor. Therefore, the range that ultraviolet rays can irradiate is limited, and the effect of disinfection and sterilization is not ideal.

Embodiment 1

[0012] Embodiment 1. The structure of the present embodiment ultraviolet disinfection and sterilization device can be from Fig. 1 and figure 2 See in, it contains the ultraviolet lamp 2 with lamp holder 2a, electric wire 2b, power switch 2c and the protective tube 1 that is installed on the periphery of ultraviolet lamp.

[0013] When in use, the device of the present invention can be placed in a ventilated place in a manner of hanging or being fixed with a bracket, such as an air-conditioning air outlet placed in a room, and the two open ends of the protective tube will avoid people or animals; then turn on the switch 2c Begin to carry out ultraviolet disinfection and sterilization to the air flowing into the protective tube; at this time, the flowing air entrains the bacteria contained on the surface of the object into the protective tube 1, and the sterilized air comes out from the other end of the protective tube until The entire room and its contents are clean before turn...

Embodiment 2

[0014] Embodiment 2. The structure of the ultraviolet disinfection and sterilization device of the present embodiment can be seen from Fig. 3, and it is different from Embodiment 1 in that: ventilator 3 can be housed in its protective tube 1, with forced air circulation, Improve the efficiency of disinfection and sterilization. It is suitable for disinfection and sterilization of unventilated rooms.

Embodiment 3

[0015] Embodiment 3. The structure of the ultraviolet disinfection and sterilization device of this embodiment can be seen from Figure 3, and it is different from Embodiment 2 in that: the ventilator 3 is a suction fan. It can suck the air in the room from the right end of the protective tube 1, and pass through the ultraviolet lamp 2 in the protective tube.

Abstract

An ultraviolet sterilizer for sterilizing the air in the room by air circulation is composed of the ultraviolet lamp with holder, conducting wire and switch. It features that the ultraviolet lamp hasa protecting tube in which said ultraviolet lamp is contained. The air flowing through the said protecting tube is sterilized. Its advantages are high sterilizing efficiency, no influence to human activity, and low cost.

Description

technical field [0001] The invention relates to a device capable of disinfecting and sterilizing objects. In particular, it is a device that uses ultraviolet rays to sterilize the air in the room and the objects in the room through the circulation of the air. Background technique [0002] Chinese patent 98111010 discloses a kind of household ultraviolet disinfection and sterilization device, and it is made up of ultraviolet lamp, lamp holder, electric wire, power plug, and its ultraviolet lamp is to adopt mercury lamp or electric arc. Its shortcoming is: 1) when it is sterilizing, people must leave the room, to avoid the irradiation of ultraviolet rays, even this room is closed, in case other people stray into it by mistake; People feel inconvenience for this reason; 2) it only Disinfect and sterilize places that can be irradiated by ultraviolet rays. For some places that cannot be irradiated, such as the space at the bottom of tables, cabinets, beds and their stored items,...
