A multifunctional disinfection and sterilizer

technical field

The utility model relates to the field of air disinfection and purification, in particular to a multifunctional disinfection and sterilizer.

Background technique

Wardrobe, shoe cabinet, refrigerator and other furniture and appliances used as home decoration and storage items have brought a lot of convenience to people's life, but also brought some unspeakable suffering to people:

1. In the rainy season, the air is humid, and the wardrobe and shoe cabinet are prone to damp. After a long time, they will become moldy, which will leave black spots on the clothes on the wardrobe, which will not only cause damage to the clothes, but also cause peculiar smell and breed bacteria , fungus, etc. If the wardrobe or shoe cabinet is not sterilized in time, it will make people susceptible to bacterial infection and cause jock itch, Hong Kong athlete's foot and other diseases;

2. Wardrobe and shoe cabinets are bulky, fixed and cannot be moved, and they are also wood products, so it is very inconvenient to clean and disinfect the wardrobe;

3. The particleboard, MDF, plywood and other wood-based panels used in the wardrobe contain a large amount of formaldehyde, which will pollute the air and be extremely harmful to human health.

4. Foods such as vegetables and fruits placed in the refrigerator are in a relatively humid environment for a long time, which is easy to breed various bacteria and microorganisms. The pesticide residues themselves will endanger human health.

At present, wardrobes, shoe cabinets, etc. are all used for moisture absorption and purification with moisture absorbers, air fresheners, etc. This method does not have the effect of disinfection and sterilization. Similar to the methods used in wardrobes and shoe cabinets, refrigerators are generally cleaned by means of absorbing and purifying odors, and do not have the functions of disinfection, sterilization and degradation of pesticide residues.

There are still many shortcomings in the current disinfection and purification methods:

1. There are many disadvantages in the disinfection and sterilization method of ultraviolet (abbreviated as UV) ray direct irradiation method: firstly, ultraviolet light has a strong aging effect, direct irradiation will accelerate the aging of fabrics, plastics and coatings, and seriously damage clothing and furniture paint films , the inner box of the refrigerator, etc., may even cause secondary pollution due to aging products, which is harmful to health; secondly, as a mobile device, direct exposure to ultraviolet light is easy to cause ultraviolet light leakage, and ultraviolet light will cause serious damage to the human body, especially the eyes. , there are potential safety hazards; finally, because light has the characteristics of straight-line propagation, the direct ultraviolet light irradiation sterilization method is only effective for the part of the outer surface facing the light source, but not for the sterilizing effect on the back-to-light or sheltered places, so the single The sterilizing effect of ultraviolet light is very limited, and it is impossible to thoroughly and efficiently sterilize the clothes, shoes or fruits and vegetables in the refrigerator that need to be sterilized.

2. Shortcomings in existing products using an ozone generator to generate ozone to sterilize objects in a small space: a Chinese patent with application number 201220080509.8 discloses a portable sterilizer, which includes a portable housing with a control device inside the housing. board, an ozone generator and a battery 700 for power supply, the housing is provided with a control button, the output end of the control button is connected to the drive end of the ozone generator and the control board, and the housing is provided with an output connected to the ozone generator and Via hole for external atmosphere. This technical solution uses the diffusion of ozone in the air to solve the problem of disinfection and sterilization in small closed spaces, but there are also obvious technical defects. First, the ozone generator used to generate ozone is a high-voltage electrical device, which has high-voltage exposure to the air. Electrodes, in a humid environment, there are safety hazards such as high-voltage ignition and leakage; secondly, due to the very long attenuation period of ozone, there is still a large amount of surplus ozone in the space after the disinfection process is completed. If consumers open the cabinet door at this time , high concentration of ozone will make consumers feel pungent and unpleasant, seriously affecting the consumer experience, and ultra-high concentration of ozone will also endanger the health of consumers; moreover, the disinfection and sterilization method of this scheme is relatively simple, and it lacks classification for different pollution sources Thorough and effective treatment; finally, in terms of control, this technology uses a button to control the switch of the product, which has potential safety hazards. If the consumer turns on the sterilizer and forgets to turn it off, the ozone generator will always release high-concentration ozone. The ozone seriously exceeds the standard. If the consumer does not close the cabinet door in this case, a large amount of ozone will be continuously released into the external environment, causing the ambient ozone to exceed the standard and endangering the health of consumers.
