Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1, the new fan with internal circulation function provided by the embodiment includes a housing 1, a filter element assembly is arranged in the housing 1, an air inlet and an air outlet are respectively arranged on two sides of the housing 1, an air inlet pipe 2 is fixed on the air inlet, an air outlet pipe 3 is fixed on the air outlet, a return air inlet is further arranged at the top of one side of the housing close to the air inlet, a return air pipe 4 is fixed on the return air inlet, a first air valve 5 is arranged in the air inlet pipe 2, a second air valve 6 is arranged in the return air pipe 4, and a fan 7 is further arranged inside the housing 1 on the inner. The shell 1 is further provided with an electric control box 8, and the electric control box 8 is electrically connected with the fan 7, the first air valve 5 and the second air valve 6.

The filter element assembly of the embodiment comprises a primary filter screen 9, a medium filter screen 10 and a high-efficiency filter screen 11, wherein the primary filter screen 9 is used for preventing allergens such as mosquitoes or catkin from flying in and reducing the risk of blockage; the medium-efficiency filter screen 10 is used for filtering PM10 pollen allergens, the filtering efficiency reaches 95.1%, the burden of the subsequent high-efficiency filter screen is reduced, and the service life of the high-efficiency filter screen is prolonged; the high-efficiency filter screen 11 is used for strong sterilization and removing PM2.5, and the filtering efficiency of particles above PM2.5 of the whole machine is over 99.9 percent. In addition, in this embodiment, the inner wall of the casing 1 is provided with a plurality of parallel accommodating grooves 12, and the primary filter 9, the intermediate filter 10 and the high efficiency filter 11 are detachably mounted in the accommodating grooves 12.
