Problems solved by technology
Although the air is driven to flow through the O-type filter when the axial flow impeller rotates, the air purification function can be realized; but to install the air filter device, it is still necessary to remove the blades of the electric fan, install the axial flow impeller and filter, and install More cumbersome, in view of this, it is necessary to propose a solution that can easily achieve indoor air purification

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] Such as Figure 1-5 As shown, the air filter device includes a casing body 1 and a filter device arranged on the casing body 1, the casing body 1 includes a first casing 11 and a second casing 12, and the first casing 11 has The first notch 111 is formed inwardly, and the second case 12 has a second notch 121 formed by inwardly recessing. When the first case 11 fits on the second case 12, the first notch 111 and the second case The end faces of the two notches 121 cooperate with each other to form an "O"-shaped frame that can fasten the casing body 1 together with the filter device on the fan motor casing 10 . In this article, the fan motor casings on the market are all set outside the rear grille of the fan. The "front" here is defined as the direction in which the gas is blown from the fan, and the opposite direction is defined as "f...

The invention relates to an air filter device. The air filter device comprises a housing main body and a filter device arranged on the housing main body. The air filter device is characterized in that the housing main body comprises a first housing and a second housing, wherein the first housing has a first notch which is formed by sinking inward, the second housing has a second notch which is formed by sinking inward, and in a state of match of sections of the first housing and the second housing, a frame which can fasten the housing main body together with the filter device to a fan motor housing. Compared with the prior art, the air filter device provided by the invention has the advantages that the air filter device overcomes the problem that in the prior art, the original fan structure needs to be disassembled and replaced when the air filter device is mounted, and the air filter device can be detachably mounted on the motor housing behind the fan. In addition, as the housing main body which is formed by the first housing and the second housing is 0-shaped, the air filter device, together with the filter device, can be fully coated in a post-posed mesh enclosure of the fan for purifying air, and the air filter device has the characteristics of simple structure, convenience in use and low mounting cost.
Description
technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air filtering device detachably installed on a fan. Background technique [0002] At present, the air purifiers on the market are integrated with many parts, which are generally a kind of integrated device that is relatively difficult to disassemble. 》Discloses such a dust collection filter for fans, which has a bottom cylindrical dust collection filter and a safety guard SG installed on the fan EF, and makes the fan EF work in the dust collection operation state, which involves a collection The dust filter is provided with a cylindrical side filter portion, a front filter portion sewn to a leeward opening of the side filter portion to block the opening, and the side filter portion has an opening on the windward side. The installation mouth of the installation guard SG is not only expensive, but usually costs several thousand yuan or more. [0003] And a...
