Description
Technical Field
The present utility model relates to an air cleaner.
Background
Currently, there are different types of air cleaners on the market. Common air purifiers include a cross-flow impeller fan, a filter screen, and a tank. The cross-flow impeller fan is provided with wind blades on one side, and the motor drives the cross-flow impeller fan to rotate, so that the cross-flow impeller fan can suck air from one side. The fan and the motor are arranged in the box, and an air inlet and an air outlet are arranged in the box. The air inlet is located near the air inlet side of the cross-flow impeller fan. Air is drawn in from the air inlet, filtered through a filter screen and blown out from the air outlet. Because the fan blade of the cross-flow impeller fan is a single-side fan blade, the air inlet of the air purifier with the structure is small in size, and the cleaning efficiency is low.
Therefore, in order to improve the filtering effect, an air purifier with a double-sided filtering structure, a bidirectional through-flow impeller fan, a motor and a box body exist in the market at present. The motor is connected to two bidirectional through-flow impellers, air inlets are arranged on two sides of the box, and a filter screen is arranged at each air inlet.
Although the bidirectional cross flow impeller fan with the structure can increase the air inflow per unit time, the filter screen adopting the result is easy to grow a large amount of bacteria on the contact surface of the filter screen and the cross flow fan, has low purification efficiency and influences the air purification effect.

An ultraviolet sterilizing lamp comprises a lamp shade and an ultraviolet lamp tube positioned in the lamp shade.
The filter screen mounting groove structure is optimized, the first filter screen does not prop against the air inlet of the filter screen mounting groove, and a gap exists between the first filter screen and the air inlet of the filter screen mounting groove.
Further preferably, the structure is that the spacer is arranged on the end face of the filter screen mounting groove, and the outer end of the spacer props against the first filter screen.
In order to increase the sterilization effect, the ultraviolet germicidal lamp is arranged in the filter screen mounting grooves at the left side and the right side and is arranged in each filter screen mounting groove, and the ultraviolet germicidal lamp irradiates a gap formed by the first filter screen at the air inlet.
In order to adapt to sterilization between gaps, the lampshade is strip-shaped and is positioned at the lower end of the air inlet.
When the air purifier is used, the filter screen is arranged in the filter screen mounting groove, the air inlet grid cover is closed to finish the installation of the filter screen, the cross flow fan is opened, air enters from two sides of the air purifier, and is filtered by the second filter screen and the first filter screen and blown out from the air outlet at the upper side, so that the purification of the air is finished.
The utility model has the beneficial effects that: 1. the air purifier's air inlet has two wind channels about, and the filter screen of left and right sides has first filter screen and second filter screen alone, and the inboard is equipped with ultraviolet ray disinfection lamp and disappears the air current between filter screen and clearance and kill, and air purification's effect is good. 2. The ultraviolet disinfection lamp disinfects the first filter screen when disinfecting the air current for can not breed harmful bacterium on the first filter screen, improve the life of filter screen.
