Detailed Description

To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 1-3, the present invention discloses a wall-mounted air sterilizer, which comprises a rear casing 1 with a wall-mounted structure (for example, the wall-mounted structure is a hook or a hanging hole) on the back side, a front panel covering the rear casing 1, a first bracket 51 arranged between the rear casing 1 and the front panel, an air guide channel 6 arranged on the first bracket 51, a cross flow fan 7 (or a cross flow fan) arranged in the air guide channel 6, and a plasma generator 9; the top end face of the rear shell 1 is provided with an air inlet 11, the front panel is provided with an air outlet 31, and two ends of the air guide channel 6 are respectively communicated with the air inlet 11 and the air outlet 31; the included angle between the air outlet direction and the air inlet direction of the cross flow fan 7 is larger than 90 degrees, air can be sucked from the air inlet 11 to the air guide channel 6 and sent to the air outlet 31, and air flow flows smoothly in the air guide channel 6, so that the wind resistance is reduced, and the noise generated by work is reduced; the plasma generator 9 is disposed near the air outlet 31.

When the cross flow fan 7 works, air is sucked from the air inlet 11 to the air channel, air flow is formed in the air channel and blown to the air outlet 31, when the air flow passes through the plasma generator 9, positive ions and negative ions generated by the plasma generator 9 are taken out and blown out from the air outlet 31, and the ambient air is sterilized and purified by the positive ions and the negative ions.
