Description

Disinfecting and sterilizing dust collector

Technical Field

The utility model relates to the technical field of dust collectors, concretely relates to disinfection dust catcher.

Background

Even though the currently recognized HEPA (high Efficiency particulate air) filter element with the highest filtering Efficiency is adopted in the existing dust collector product, the PM2.5 particles and dust mites in the air can only be filtered, and various bacteria and viruses still exist in the dust and garbage after the filtration. In addition, when the dust in the dust barrel (or the dust cup) of the dust collector is cleaned after the dust collector is used, bacteria and viruses in the dust can be contacted, secondary pollution can be caused to an operator of the dust collector, and safety cannot be guaranteed.

In the actual family life, the garbage in the dust barrel is not cleaned after dust collection every time. Then the garbage can is cleaned for more than a few days or a week, and bacteria and viruses in the garbage can exist in the dust barrel all the time. When the dust bin is opened to dump the garbage, bacteria and viruses in the garbage can be dispersed in the air again along with the garbage dumping process.

Even some dust collectors which can sterilize and remove mites on the market are designed on a floor brush, and air inlet speed is high in the dust collection process, so that bacteria cannot be killed in a short time. If the target bacteria or viruses are to be killed, the sterilizing ultraviolet lamps on the market need to be irradiated for a long time, wherein the irradiation time is more than tens of minutes, and the actual operation is unlikely to be realized.

Therefore, the existing dust collector cannot effectively kill bacteria and viruses.

Optionally, an opening is formed in a position, corresponding to the UV LED, of one surface of the bottom cover 1 facing the dust cup, and the transparent member is a quartz wafer 4 for plugging the opening. Further, the opening can be a circular opening formed by hollowing out the central part of the bottom cover 1, and the quartz wafer 4 is hermetically embedded in the circular opening, so that the space for installing the PCBA 2 in the bottom cover 1 is separated from the space in the dust cup to isolate the air circulation in the dust cup.

Optionally, in order to ensure the effect of the UV LEDs 3 on killing bacteria and viruses, a group of multiple UV LCDs 3 may be disposed on the PCBA 2, for example, four or more UV LEDs 3 are disposed, and the optical power of each UV LED 3 is not less than 5 mW, so that the total power is 20mW or more.

Optionally, the PCBA 2 in the bottom cover 1 and the host circuit in the host are connected and disconnected by arranging electrodes. Specifically, another PCB (Printed Circuit Board) 5 electrically connected to the PCBA 2 where the UV LED 3 is located is further disposed in the bottom cover 1, a first electrode 6 is disposed on the PCB 5, and the first electrode 6 is electrically connected to the PCBA 2; a second electrode 11 can be arranged in the host machine at a position close to the first electrode 6, and the second electrode 11 is connected with a host machine circuit in the host machine. Alternatively, the second electrode 11 may be an elastic electrode.

When the bottom cover 1 is closed, the first electrode 6 and the second electrode 11 are in contact to realize electrical connection, and then the host circuit can supply power to the PCBA 2, so that the UV LED 3 is lightened to perform disinfection and sterilization; when the bottom cover 1 is opened, the first electrode 6 and the second electrode 11 are disconnected, and the UV LED 3 does not operate. In this way, it is ensured that the UV LED 3 does not operate when the bottom cover 1 is opened, thereby avoiding damage to the operator of the vacuum cleaner.

Optionally, in some embodiments, the bottom cover 1 is mounted on the main machine through a rotating shaft 7, and a torsion spring 10 may be sleeved on the rotating shaft 7, where the torsion spring 10 is used to apply a torsion force so that the bottom cover 1 is fastened to the bottom of the main machine.
