Embodiment 1

[0024] Such as figure 1 , figure 2 and image 3 As shown, an air purifier for convenient replacement of the filter screen includes a housing 1, an air inlet, a filter device, a fan 3 and an air outlet, the air inlet is located at one end of the housing 1, and the air outlet is located at the The other end of the casing 1 is a cuboid, the filter device and the fan 3 are respectively arranged in the casing 1, the fan 3 is fixed on the inner wall of the casing 1 near the air outlet side, and the fan 3 and the The power cord is connected, and the filter device is close to the air inlet side. The filter device includes a frame fixing part, a first frame body 7, a second frame body 8, blades 9 and a third filter screen 10, and the frame body is fixed fixed on the opposite sides of the inner wall of the housing 1, one side of the first frame body 7 and the second frame body 8 is connected by a rotating shaft, and the contact surfaces of the first frame body 7 and the second frame ...

Embodiment 2

[0030] Such as figure 2 As shown, the shape and size of the first frame body 7 and the second frame body 8 are the same, the blades 9 in the first frame body 7 are parallel to the blades 9 in the second frame body 8, and the blades 9 of the blades 9 The thickness is greater than the thickness of the first frame body 7 and not more than twice the thickness of the first frame body 7 .

[0031] After putting into the third filter screen 10, close the first frame body 7 and the second frame body 8, and the excess part of the blade 9 relative to the thickness of the first frame body 7 and the second frame body 8 can make the third filter screen 10 It forms a wavy shape, which can be well fixed between the first frame body 7 and the second frame body 8, and increases the area where the air to be purified passes through the third filter screen 10, thereby increasing the air purification effect. The third filter screen The net 10 is a flexible composite filter.

Embodiment 3

[0033] Such as image 3 As shown, the shape and size of the first frame body 7 and the second frame body 8 are the same, the blades 9 in the first frame body 7 are perpendicular to the blades 9 in the second frame body 8, and the blades 9 of the blades 9 The thickness is equal to the thickness of the first frame body 7 .

[0034]The blades 9 in the first frame body 7 are perpendicular to the blades 9 in the second frame body 8, which can better fix the third filter screen 10, so that the third filter screen 10 can be placed relatively flatly between the first frame body 7 and the second frame body 8. Between the second frames 8, the filter screen mainly placed is a rigid filter screen.

Abstract

An air purifier convenient for filter screen replacement comprises a casing, an air inlet, a filtering device, a fan and an air outlet. The filtering device comprises frame fixing portions, a first frame, a second frame, blades and a third filter screen. The frame fixing portions are fixed to opposite sides of the inner wall of the casing, one side of the first frame is connected with one side ofthe second frame through a rotating shaft, and the blades are fixed to the contact surface of the first frame and the second frame at equal intervals. When the first frame and the second frame are closed by the rotating shaft, the third filter screen is clamped between the blades of the first frame and the second frame; a filter screen replacement door is formed in one side, not provided with theframe fixing portions, of the casing. Through opening and closing of the first frame and the second frame, the third filter screen can be freely put in and fastened or easily taken out, thereby beingconvenient to replace.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to an air purifier for convenient replacement of filter screens. Background technique [0002] At present, air purifiers mainly rely on filter elements to absorb pollutants in the air. Pollutants in the air generally include dust, PM2.5, formaldehyde, bacteria, etc. After a period of time after the filter element absorbs pollutants, if it is not cleaned in time, it will cause secondary pollution. Secondary pollution not only reduces the efficiency of the air purifier to purify the air, but also may discharge the previously adsorbed pollutants, causing secondary pollution to the air. Therefore, it is necessary to clean or replace the filter element of the air purifier frequently. When replacing the filter element, it is often necessary to replace the filter element and the frame fixing part fixed on the filter element. When cleaning after replacement, the filter el...
