Description

Technical Field

[0001] The utility model relates to the field of air purifiers, in particular to an air purifier shell. Background Art

[0002] At present, a Chinese utility model with the announcement number CN210717898U discloses an air purifier housing, including a housing and a base, a self-locking block is arranged on the base, and a self-locking slot used in conjunction with the self-locking block is arranged on the inner wall of the bottom of the housing, and the base is screwed to the opening of the bottom surface of the housing through the cooperation between the self-locking block and the self-locking slot. The utility model also discloses an air purifier, including a housing, an air duct is arranged in the housing, a filter assembly and a fan assembly are arranged in the air duct, and the housing is the above-mentioned air purifier housing. The self-locking structure used in conjunction with the housing and the base described in the utility model is easy to assemble and effectively avoids the problem of assembly gap. The air inlet grilles are evenly distributed in the middle and lower part of the housing, and the air enters the whole machine through the air inlet, and the contact area between the air and the filter is larger.

[0003] Although the existing air purifier shell is equipped with a filter assembly to reduce the dust in the air from falling onto the fan blades, there are still other problems in the process, such as it is not convenient to quickly disassemble and assemble the filter plate. The filter plate is connected to the top seat by internal card or screw fixing. When there is too much dust attached to the fan blades under the filter plate and needs to be cleaned, it is necessary to use tools to remove it, which reduces the cleaning efficiency of personnel and has poor limiting effect on the filter element. The filter element is directly pushed into the interior when in use. Although it will not shift in a static state, when the shell is pushed, the position of the internal filter element will deviate, and personnel need to readjust it, which has low practicality. In order to solve the above-mentioned problems, we propose an air purifier shell. Utility Model Content

[0004] The utility model aims to provide an air purifier shell, which solves the problem that the existing purifier shell is laborious to assemble and disassemble the filter plate and the filter element has poor stability after being placed.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: an air purifier shell, including a machine frame, the bottom and the inside of the machine frame are respectively bolted with a base and a mounting plate, both sides of the machine frame are clamped with air intake side plates, a fixed frame is installed inside the base, a fixed plate is bolted at the bottom of the fixed frame, a limiting convex plate is arranged inside the fixed frame, a first fixing spring is bolted between the inside of the limiting convex plate and the fixing plate through a spring fixing sheet, a top seat is bolted at the top of the machine frame, a filter plate is placed inside the top seat, mounting grooves are symmetrically opened on the surface of the filter plate, a card plate is clamped inside the top seat through a card slot, and a second fixing spring is bolted between the other side of the card plate and the mounting groove through a spring fixing sheet.

[0006] The above technical solution can improve the limiting effect of the filter element and avoid the filter element from being misplaced when the outer shell is hit. It is highly practical and can facilitate the quick disassembly and assembly of the filter plate. The operation is simple and convenient, which speeds up the cleaning efficiency of the internal fan blades.

[0007] The utility model is further configured as follows: a limiting rod is welded to the bottom of the limiting convex plate, and the other end of the limiting rod penetrates and extends to the bottom of the fixing plate.

[0008] By adopting the above technical solution, the limiting convex plate can be limited by setting the limiting rod to prevent the limiting convex plate from tilting during the process of moving up and down.

[0009] The utility model is further configured as follows: a baffle is bolted inside the base.

[0010] By adopting the above technical solution, the interior of the base can be sealed by setting the baffle to prevent dust and impurities from entering.

[0011] The utility model is further configured as follows: a pull rod is welded on the top of the clamping plate, and a sliding groove used in conjunction with the pull rod is opened on the top of the filter plate.

[0012] By adopting the above technical solution, through the provision of the pull rod and the sliding groove, it is convenient for personnel to pull the pallet by hand.

[0013] The utility model is further configured as follows: the first fixing spring and the second fixing spring are both made of carbon spring steel.

[0014] By adopting the above technical solution, the first fixed spring and the second fixed spring have the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0015] The utility model is further configured as follows: the machine frame, the base, the mounting plate, the top seat and the air intake side plate are all made of ABS material.

[0016] By adopting the above technical solution, the machine frame, base, mounting plate, top seat and air intake side plate have the characteristics of high strength, high toughness and good flame retardant effect.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model removes the filter element cover plate first, then puts the filter element in and presses the limiting convex plate downward. When pressed, the limiting convex plate moves downward and presses the first fixing spring. When the top of the limiting convex plate is pressed down to be flush with the top of the fixing frame, the filter element is put on the convex end of the limiting convex plate and the hand is released. When the first fixing spring rebounds, it drives the limiting convex plate to move up to position the filter element, which can improve the limiting effect of the filter element and avoid the filter element from being misplaced when the shell is hit. It is highly practical.

[0019] 2. The utility model uses both hands to grasp the two pull rods and push them inwards. When the pull rods are pushed, they drive the card plate to move into the installation groove. When the card plate moves, it will not only compress the second fixed spring to make it enter a contracted state, but also separate from the card groove in the top seat. When the pull rods are pushed inwards to the bottom, the filter plate can be taken out by lifting it up, which can facilitate the quick disassembly and assembly of the filter plate. The operation is simple and convenient, which speeds up the cleaning efficiency of the internal fan blades. BRIEF DESCRIPTION OF THE DRAWINGS
