Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification box which is convenient for replacement and care. Background Art

[0002] An air purifier is a device for purifying indoor air. According to the air purifier's technology for removing particles from the air, there are mainly mechanical filter types, which have good collection effects on fine particles but have large wind resistance. In order to obtain high purification efficiency, the filter has large resistance, and the filter needs to be dense, which reduces its lifespan and requires regular replacement. The filters of existing air purifiers are usually pull-out type, that is, the old filter can be directly pulled out and the new filter can be inserted into the filter slot of the air purifier to achieve filter replacement. However, if the filter slot and the filter fit tightly, the installation of the new filter will be very unsmooth, making it very inconvenient to disassemble and assemble the filter. If there is a gap between the filter and the filter slot, the filter frame and the filter slot will frequently collide during use, generating noise. Summary of the invention

[0003] The utility model aims to provide an air purification box which is convenient for replacement and maintenance, so as to overcome the above-mentioned defects in the prior art.

[0004] According to the utility model, an air purification box that is convenient for replacement and care includes a working box, a filter disc is provided at the front end of the working box, an opening that opens upward is provided at the rear end part of the working box, a purification box is provided at the opening, a working chamber is provided in the working box, the opening is communicated with the working chamber, two sealing guide plates distributed front and back are fixedly provided on the left and right side walls of the working chamber, a filter screen is connected to the front and rear ends of the purification box, an absorption box is provided between the two filter screens, the sealing guide plate abuts against the filter screen, abutment plates are fixedly provided on the left and right side walls of the working chamber, and two sealing guide plates are fixedly provided on the left and right ends of the purification box The protrusions are distributed up and down, and the left and right side walls of the working chamber are connected with fixed blocks. The fixed blocks are rotatably connected with hinged magnetic blocks near the protrusion ends, and the fixed blocks correspond to the hinged magnetic blocks on the left and right. Each of the fixed blocks is provided with two upper and lower magnets. Two left-right symmetrical handles are fixedly provided on the upper end of the purification box. A fixing frame is fixedly embedded in the front part of the working chamber, and a fixing disk is threadedly connected to the rear end of the fixing frame. The front end of the fixing disk is connected to an exhaust fan evenly distributed in the circumference, and evenly distributed air outlets are opened on the circumferential end surface of the fixing frame, and evenly distributed wind guide plates are fixed on the circumferential end surface of the fixing frame.

[0005] The beneficial effects of the utility model are:

[0006] During the mobile installation process of the purification box, the left and right ends of the purification box are installed and disassembled under the guidance of the filter and the abutment plate, and are sealed by the filter to allow air to flow through the filter and the absorption box for filtering and purification. The abutment between the protrusion and the hinged magnetic block ensures that the filter device is reliably pressed, which facilitates installation and disassembly and prevents the filter device from shaking due to the flow of air. The air is drawn into the fixed frame and the fixed plate by the exhaust fan and sprayed out through the air outlet. Under the guidance of the air guide plate, the air is completely in contact with the filter to improve the utilization rate of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0021] Reference Figure 1-Figure 10 According to an embodiment of the utility model, an air purification box that is convenient for replacement and care includes a working box 10, a filter disc 12 is provided at the front end of the working box 10, an opening opened upward is provided at the rear end of the working box 10, a purification box 11 is provided at the opening, a working chamber 25 is provided in the working box 10, the opening is communicated with the working chamber 25, two sealing guide plates 17 distributed front and back are fixedly provided on the left and right side walls of the working chamber 25, a filter screen 18 is connected to the front and rear ends of the purification box 11, an absorption box 23 is provided between the two filter screens 18, the sealing guide plate 17 abuts against the filter screen 18, abutment plates 26 are fixedly provided on the left and right side walls of the working chamber 25, and a filter screen 18 is fixedly provided on the left and right sides of the purification box 11. Two protrusions 21 are distributed up and down, and the left and right side walls of the working chamber 25 are connected with fixed blocks 19. The fixed blocks 19 are rotatably connected with hinged magnetic blocks 22 near the ends of the protrusions 21. The fixed blocks 19 correspond to the hinged magnetic blocks 22 on the left and right. Each fixed block 19 is provided with two upper and lower magnets 20. The upper end of the purification box 11 is fixed with two left-right symmetrical handles. The front part of the working chamber 25 is fixedly embedded with a fixed frame 13, and the rear end of the fixed frame 13 is threadedly connected with a fixed disk 24.
