Description

A disinfection and sterilization vacuum cleaner

This application claims the priority of the Chinese patent application with the application number CN202010649830.2 and the invention titled "A sterilizing and sterilizing vacuum cleaner", which was submitted to the Chinese Patent Office on July 8, 2020, the entire contents of which are incorporated into this application by reference .

technical field

The invention relates to the technical field of vacuum cleaners, in particular to a disinfection and sterilization vacuum cleaner.

Background technique

Existing vacuum cleaner products can only filter PM2.5 particles and dust mites in the air even if they use the HEPA (High Efficiency Particle Air) filter element, which is currently recognized as having the highest filtration efficiency. A variety of bacteria and viruses exist. Moreover, after using the vacuum cleaner, when cleaning the garbage in the dust bucket (or dust cup) of the vacuum cleaner, it is possible to come into contact with the bacteria and viruses in the garbage, which will cause secondary pollution to the operator of the vacuum cleaner, and the safety cannot be guaranteed. .

In actual family life, not every time you vacuum the garbage in the dustbin. Then it will only be cleaned once a few days or even more than a week, and the bacteria and viruses in the garbage will always exist in the dust bin. When the dust bin is opened to dump the garbage, the bacteria and viruses in the garbage may spread into the air again along with the process of dumping the garbage.

Even if there are some so-called vacuum cleaners on the market that can sterilize and remove mites, because the devices for removing mites and sterilizing are designed on the floor brush, and the air intake speed is very fast during the vacuuming process, it cannot kill bacteria in a short time. If you want to kill the target bacteria or viruses, the anti-virus ultraviolet lamps on the market need to be irradiated for a long time, and the irradiation time is more than tens of minutes. In actual operation, it is impossible to achieve.

It can be seen that the existing vacuum cleaners cannot effectively kill bacteria and viruses.
