Description

Fully automatic ultraviolet germicidal lamp

Technical field:

The utility model designs a sterilizing device, in particular a fully automatic ultraviolet sterilizing lamp which is simple in structure, saves electric energy, can sterilize and prevent harm to human body.

Background technique:

In the human living environment (air, water, food, etc.), there are many kinds of bacteria and viruses, which often use human breathing, eating, drinking water and contact with other objects to enter the human body, and the pathogenic bacteria and viruses will be It causes people to contract various diseases and seriously affects human health. Ultraviolet sterilization has been discovered and used in the 1940s. This is also the best sterilization method recognized in the world, that is, it can kill pathogenic bacteria on the surface of objects and in liquid or air, and prevent various bacteria and viruses. Breed and spread. Therefore, at present, ultraviolet rays have been used for sterilization in hospitals, laboratories, biological institutes, drinking water sources and other places that require sterility. However, because the existing ultraviolet sterilizing device only connects the ordinary manual power switch and the ultraviolet lamp in series, and the operation and stop of the ultraviolet lamp are controlled by the power switch, the human body may enter into the ultraviolet radiation during the working period of the ultraviolet lamp. Direct irradiation by ultraviolet rays is not conducive to health, so that the use time, application range and sterilization effect of existing ultraviolet sterilizers are all affected by the above-mentioned disadvantages.

Invention content:

The utility model aims to solve the above-mentioned technical problems in the prior art, and provides a fully automatic ultraviolet sterilizing lamp which has a simple structure, saves electric energy, can sterilize and prevent harm to the human body.

The technical solution of the utility model is: a fully automatic ultraviolet sterilizing lamp, which has a power switch K and an ultraviolet sterilizing lamp tube connected with the power switch K. Control circuit and infrared sensor control circuit.

The power switch K is a two-way changeover switch, and the other direction of the power switch K is connected to the lighting lamp.

The power switch of the utility model is a two-way switch, and the other direction can be connected with the lighting lamp when in use, so that the ultraviolet germicidal lamp tube is in the stop state under the lighting state, and a time controller and an infrared sensor controller are also provided at the same time, which can Automatically control the daily working time of the ultraviolet germicidal lamp and ensure that the sterilization can only be carried out when there is no one in the ultraviolet irradiation range. It has the advantages of simple structure, energy saving, sterilization and prevention of harm to the human body.

Description of drawings:

Fig. 1 is the circuit principle block diagram of the utility model embodiment.

Detailed ways:

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figure 1: there is a power switch K, which is connected to the ultraviolet germicidal lamp tube, and a time control circuit and an infrared induction control circuit are connected in series in the circuit between the power switch K and the ultraviolet germicidal lamp tube. The time control circuit and the infrared induction control circuit are all selected from the prior art, and the power switch K can also be integrated with the time controller. The power switch K can be a two-way transfer switch, wherein one direction (OB) is connected to the ultraviolet germicidal lamp tube, and the other direction (OA) can be connected with the existing lighting lamp during use, or the other direction of the power switch K can be connected to the other direction during production. One direction (OA) is connected with the lighting lamp, that is, the lighting lamp is designed as an assembly of the utility model.

working principle:

1. The power switch K controls the time controller, the infrared sensor controller and the ultraviolet germicidal lamp to lose power when the light is on (occupied), and to be powered on when the light is off (no one);

2. Set the working time (multiple times) and time each day through the time control circuit to automatically control the work and stop of the ultraviolet germicidal lamp tube. The best method is the lamp power of 0.7~1W/m3, every day 1-4 times, irradiating for 1 hour each time, can achieve the sterilization effect of killing 99.99% of various fungi;

3. The infrared sensor controller can detect the existence of the human body, regardless of whether the ultraviolet germicidal lamp starts to work, such as when there is a person within the ultraviolet irradiation range, the infrared sensor controller will output a switch signal to control the ultraviolet germicidal lamp not to work; when the person leaves After that, the sterilization work can be carried out, and the delay can be set to 30 seconds, that is, the sterilization work can be carried out after the human body leaves for 30 seconds.

The utility model ensures that the sterilizing work is carried out only under the condition that the illuminating lamp is off, the set working time period and no one is in the ultraviolet irradiation range, and the application range is wide. It is mainly suitable for sterilization in medical and sanitation, bacteria research, pharmaceutical industry, photochemical reaction, hospital, restaurant, hotel, train and ship station, office, office and family (bedroom, living room, kitchen, bathroom).

Claims (2)

1. a full-automatic ultraviolet germicidal lamp has mains switch K to reach the ultraviolet sterilization fluorescent tube that joins with mains switch K, it is characterized in that: also be in series with time control circuit and infrared induction control circuit in the circuit of mains switch K and ultraviolet sterilization fluorescent tube.

2. full-automatic ultraviolet germicidal lamp according to claim 1 is characterized in that: described mains switch K is a two-way reversing switch, and another of mains switch K is to joining with illuminating lamp.
