However, the filter's fixation requires control by a drive motor, consuming additional electrical energy, increasing the cost of filter installation, removal, and cleaning, and reducing the filter's cost-effectiveness. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a purifying filter for harmful gases that is easy to clean, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a purifying filter for harmful gases that is easy to clean, comprising a housing, an installation mechanism for placing the filter, and a retaining mechanism for preventing the automatic operation of some components of the installation mechanism. A fixing mechanism for securing the filter is provided on the left side inside the housing. The fixing mechanism includes a fan-shaped plate and a fixing groove. The fan-shaped plate is located on the left side of the installation mechanism, and the fixing groove is located on the left side of the installation mechanism. The inner wall of the fixing groove is in contact with the side of the fan-shaped plate. The installation mechanism is located inside the housing, and the retaining mechanism is located above the fixing mechanism.

[0008] By adopting the above technical solution, the fan-shaped plate can be rotated into the fixing groove to fix the filter screen with the fixing groove, thus avoiding the energy consumption of fixing the filter screen.

[0009] Preferably, the fixing mechanism further includes an adjustment groove and a turntable. The adjustment groove is located on the top left side of the outer casing, and a rotating groove is located at the bottom of the adjustment groove. The turntable is rotatably connected to the inner wall of the rotating groove, and a control hole is located on the rear side of the top of the turntable.

[0010] By adopting the above technical solution, the control hole on the surface of the turntable, which is located in the bottom of the adjustment groove, can be used to rotate the turntable, which facilitates the adjustment of the angle of the sector plate.

[0011] Preferably, the fixing mechanism further includes a movable groove and a rotating rod. The movable groove is formed at the bottom of the rotating groove. A retaining ring is connected to the upper part of the inner wall of the movable groove. A rotating groove is formed at the bottom of the movable groove. The bottom of the inner wall of the rotating groove is in contact with the bottom of the sector plate. The top of the rotating rod is connected to the bottom of the turntable. A retaining groove is formed on the upper part of the side of the rotating rod. The inner wall of the retaining groove is rotatably connected to the retaining ring. The bottom of the rotating rod is connected to the top of the sector plate.

[0012] By adopting the above technical solution, the position of the rotating rod can be restricted by the retaining ring in the movable groove and the retaining groove opened in the rotating rod. The rotation of the turntable drives the rotating rod to rotate, and the rotation of the rotating rod drives the sector plate in the rotating groove to rotate, which facilitates the installation and removal of the filter screen.

[0013] Preferably, the outer casing includes a housing and ventilation holes, with an adjustment groove on the top left side of the housing and ventilation holes on the front and rear sides of the housing.

The limiting groove is connected to the moving groove, and a moving block is slidably connected in the limiting groove. The top of the moving block is connected to the bottom of the fixing plate.

[0022] By adopting the above technical solution, the moving groove and the limiting groove can be used to provide space for the movement of the moving block, and the sliding connection between the moving block and the limiting groove can be used to fix the angle of the turntable.

[0023] (III) Beneficial Effects

[0024] This application provides a harmful gas purification filter that is easy to clean. It has the following beneficial effects:

[0025] 1. This easy-to-clean harmful gas purification filter uses a fixing mechanism. By inserting a finger into the adjustment groove and then into the control hole of the turntable located in the rotating groove, the finger can rotate half a turn, causing the turntable to rotate. The rotation of the turntable causes a rotating rod with a retaining groove that engages with a retaining ring in the movable groove to rotate. The rotation of the rotating rod causes the fan-shaped plate in the rotating groove to disengage from the fixing groove, allowing the filter to be directly removed for cleaning. This avoids the energy consumption of filter removal and cleaning, reduces the cost of filter removal, and improves the cost-effectiveness of filter cleaning.

[0026] 2. This easy-to-clean harmful gas purification filter, through the setting of a fixing mechanism, moves the fixing plate to the left, causing the second spring and telescopic tube in the telescopic groove to shorten, and at the same time, it causes the moving block to slide out of the limiting groove and into the moving groove, which facilitates the adjustment of the fixing mechanism, avoids the possibility of the fixing mechanism operating without human intervention, and improves the stability of the fixing mechanism.
