Example 1

As shown in figure 6, for a covering plate with the length of about 75mm and the width of about 75mm, the length A of a second wind shielding vertical plate is about 29mm, the distance D from a transverse wind shielding plate to the bottom of the covering plate is about 65mm, the distance B from the bottom of a first wind shielding vertical plate to the top of a wind shielding transverse plate is about 23mm, the distance C from the first wind shielding vertical plate to the left end surface of the covering plate is about 52mm, and the distance E from the first wind shielding vertical plate to the right end surface of the covering plate is about 24 mm. The cover plates are manufactured according to the proportion and installed on the first sterilization box, the second sterilization box and the third sterilization box, the size of the three sterilization boxes is the same, 125.5mm multiplied by 76.5mm multiplied by 45.5mm, the first sterilization box is only provided with an ultraviolet lamp, the second sterilization box is provided with an ultraviolet lamp and a fan, and the third sterilization box is provided with an ultraviolet lamp, a fan and an anion generator. The fan adopts 5V and 4000r/min, and the three sterilizing boxes adopt dual-band quartz ultraviolet lamp tubes which can emit 253.7nm ultraviolet rays and 185nm ultraviolet rays. The 253.7nm ultraviolet can effectively destroy the DNA structure of bacteria, kill bacteria and inhibit the breeding of bacteria and germs; the 185nm ultraviolet ray can be ionized with oxygen in the air to generate ozone, which is a strong oxidant and is extremely unstable at normal temperature and can be decomposed into oxygen molecules and oxygen atoms at any time. The oxygen atoms have extremely strong oxidizing power and decomposing power. Therefore, the ozone has the functions of sterilization, deodorization, mildew prevention, air freshening and the like.

Placing the three sterilizing boxes in a fully-sealed plastic container with the thickness of 50cm multiplied by 35cm multiplied by 30cm respectively, and detecting the ozone amount generated by a sterilizing box I (the ultraviolet lamp is normally opened) and a sterilizing box II (the ultraviolet lamp is normally opened) at different time by adopting an ozone concentration detector, wherein the ozone amount is shown in table 1;

the ozone amount generated by the sterilization box II (ultraviolet lamp is normally open), the fan is normally open, the circulation switch is opened for 30s and closed for 6s, the circulation switch is opened for 20s and closed for 5s, and the circulation switch is opened for 10s and closed for 5s under four states, and the sterilization box III (ultraviolet lamp and anion generator are normally open) is opened for 10s and closed for 5s under different time is detected, see table 2.

Table 1:

as can be seen from table 1, the sterilization box ii can emit ozone as soon as possible after the fan is added to the sterilization box i.

Table 2:

as can be seen from table 2 above, the fan has better effect than the fan is normally open after the fan adopts the cyclic on/off mode. Because when the fan stops, the ultraviolet ray and the air generate more ozone under the windless state, and then the fan is opened to blow out the ozone, so that the ozone concentration is higher. Meanwhile, the oxygen content can be increased by adding the negative ion generator, so that the ozone content generated in the same time can be increased, and the sterilization effect is further improved. It can be seen from table 2 that the fan is best operated in the mode of turning on 10s and turning off 5 s.

In addition, when the fan is switched on for 10s and switched off for 5s, the concentration of ozone discharged by the sterilizing box II and the sterilizing box III is detected in real time, and the detection shows that the concentration of ozone generated by the sterilizing box III which is additionally provided with the anion generator is about 0.012ppm at 10s and about 0.025ppm at 15s, but the concentration of ozone generated by the sterilizing box III is only 0.018 ppm. Because anion generator has increased oxygen content and it is located the intake chamber, and the air current is disinfected by the intake chamber entering sterilization chamber from the air inlet, therefore, can know, from the intake chamber to the exhaust vent, the time of air current in sterilization chamber is more than 10s, to the mode that fan switch-on 10s closes 5s, the time of disinfecting in sterilization chamber has reached 15s more, and the bactericidal time is longer, and bactericidal effect is good.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
