[0002] With increasing concern about air quality, air purifiers have become common devices for improving indoor air quality in homes, offices, and other places. Among them, dual-filter plasma air purifiers are widely used because they combine the advantages of both filter filtration and plasma purification. One type of plasma air purifier includes two air inlets and two filters to reduce the filtration pressure on a single filter. This type of air purifier has a more complex structure and makes filter replacement more troublesome compared to traditional single-filter air purifiers. Therefore, this utility model provides a plasma air purifier. Utility Model Content

[0006] A filter support frame is provided between the upper and lower slide rails in the same group, which slides and engages with the slide rails. A filter is provided inside the filter support frame. The filter support frame includes a fixed frame and a movable frame. The fixed frame has an open box structure, and the movable frame has a planar structure, with one end rotatably connected to the edge of the fixed frame.

[0007] The inlet and outlet are equipped with sealing plates that are detachably connected to the box body.

[0008] Based on the above solution and as a preferred embodiment, the top of the housing is provided with a control knob for controlling the fan speed.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the cross-section of the slide rail is U-shaped.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, the movable frame includes a rectangular frame and inclined reinforcing beams connected at the four corners of the rectangle.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, the first side of the rectangular frame is rotatably connected to the top of the fixed frame, and a pull ring is provided on the second side opposite to the first side.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme, the fixed frame is provided with a push-pull handle at the end of the inlet and outlet.

[0013] Based on the above solution and as a preferred embodiment, the sealing plate is detachably connected to the housing by screws.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: When replacing the filter screen, the sealing plate is first removed, then the filter screen support frame and the filter screen are slid out from the slide rail, then the movable frame is opened, the filter screen is taken out, and then the new filter screen is installed into the filter screen support frame. Finally, the filter screen support frame and the filter screen are installed back onto the slide rail and the sealing plate is connected. The operation is simple, the replacement is convenient, and the installation structure is simple and the manufacturing cost is low. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0021] like Figure 1and Figure 2 As shown, a plasma air purifier includes: a rectangular housing 1, with an air outlet 2 at the top, air inlets 3 on two opposite side walls, and an inlet / outlet 4 on the other side wall. Both the air outlet 2 and the air inlet 3 are equipped with grilles.

[0022] The enclosure 1 houses a fan 5 and a slide rail 6. The air outlet of the fan 5 faces the air outlet 2 for air delivery. The fan 5 is connected to a control device, and a control knob 11 located on the top of the enclosure 1 is also connected to the control device to control the airflow of the fan 5. The enclosure 1 also contains a plasma generator.

[0023] There are two sets of slide rails 6, each connected to the side wall with the air inlet 3. Each set has two slide rails 6, arranged symmetrically. The upper and lower slide rails 6 are respectively higher than the top and lower than the bottom of the air inlet 3. A filter support frame is provided between the upper and lower slide rails 6 in the same set, which slides and engages with the slide rails 6. A filter 7 is installed inside the filter support frame. The area of ​​the filter 7 is larger than the area of ​​the air inlet 3, so as to completely block the air inlet 3. The filter support frame slides and engages with the slide rails 6, so that the filter support frame and the filter can be removed when replacing the filter, which is simple and convenient and improves the efficiency of replacement.

[0024] Among them, such as Figure 3 As shown, the cross-section of the slide rail 6 is U-shaped, and the filter support frame fits inside the U-shape.

[0025] like Figure 4 As shown, the filter support frame includes a fixed frame 8 and a movable frame 9. The fixed frame 8 has an open, box-like structure, while the movable frame 9 has a planar structure, with one end rotatably connected to the edge of the fixed frame 8 to serve as a cover for the box-like fixed frame 8. The fixed frame 8 includes a large area of ​​gaps to allow for air circulation.

[0026] Preferably, the movable frame 9 includes a rectangular frame and inclined reinforcing beams connected at the four corners of the rectangle, which reduces obstruction to airflow while pressing down the filter screen 7. The first side of the rectangular frame of the movable frame 9 is rotatably connected to the top of the fixed frame 8, and a pull ring 12 is provided on the second side opposite to the first side so that the operator can hold the movable frame 9.

[0027] Four sealing plates 10 are provided at the inlet and outlet, which are detachably connected to the housing 1. The sealing plates 10 are detachably connected to the housing 1 by screws. Optionally, a sealing strip is provided between the sealing plate 10 and the housing 1 to ensure the airtightness of the connection.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort.
