[0002] Air filters typically consist of multiple layers of filter material to effectively capture, absorb, and filter dust, impurities, and harmful substances from the air. Their structural design directly impacts their filtration effectiveness and service life.

[0003] The purpose of sterilizing the air filter is to maintain its high-efficiency filtering performance and prevent secondary pollution. During long-term use, the air filter will not only accumulate a large amount of dust and suspended particles, but may also breed bacteria and microorganisms, thereby affecting air quality and health. As shown in the prior art of publication number CN111974092A, although this prior art heats the heat-resistant filter layer by heating it with an electric heating structure, the heat-resistant filter layer is heated to a set temperature, thereby achieving the purpose of high-temperature killing of pathogens adhered to its surface and interior. However, this prior art does not have a structure for heat insulation, which results in the loss of heat in this technical solution, and the loss of heat will affect the sterilization effect of the air filter.

[0023] Refer to the instruction manual Figure 1-5 , the utility model provides an automatic heating and sterilizing air filter structure, including a filter assembly for filtering impurities in the air;

[0024] Two sets of packaging components for sealing and heat preservation are provided outside the filter assembly;

[0025] like Figure 1-5 As shown, each set of packaging components includes a mounting frame 1 installed on the outside of the filter assembly, a mounting cavity 2 is opened inside the top of the mounting frame 1, and a movable shaft 3 movably connected by a bearing is installed inside the mounting cavity 2, and a sealing tape 4 is wrapped around the outside of the movable shaft 3, and the end of the sealing tape 4 away from the movable shaft 3 passes through the mounting frame 1 and extends to the outside of the bottom end of the mounting frame 1; a slave gear 5 is sleeved on the outside of one end of the movable shaft 3, and a main gear 6 is meshed with one end of the slave gear 5.

[0026] Specifically, through the meshing transmission of the main gear 6 and the slave gear 5, the micro motor 12 can drive the movable shaft 3 to rotate, and the movable shaft 3 then unfolds the sealing belt 4 counterweighted by the counterweight block 7, so that the sealing belt 4 can seal and close the installation frame 1, so that the heat can be concentrated inside the frame 8 and fully contact the filter screen 9.

[0027] like Figure 1 、 2As shown in Figures 3 and 5, a counterweight block 7 is installed at the bottom of the end of the sealing belt 4 away from the movable shaft 3. Through the connection between the counterweight block 7 and the sealing belt 4, the sealing belt 4 can move downward by the gravity of the counterweight block 7, thereby making the sealing belt 4 seal and close the mounting frame 1, thereby ensuring the operating stability of the sealing belt 4 and avoiding the deviation of the sealing belt 4.

[0028] like Figure 1 and 2 As shown, the filter assembly includes a frame 8, and filter screens 9 are installed inside the front and rear ends of the frame 8; the mounting frame 1 is installed on the outside of one end of the frame 8, and the filter screen 9 is installed through the frame 8, and then the impurities in the air are filtered by the filter screen 9, and electric heating plates 10 are installed inside both ends of the frame 8, and the top of the two electric heating plates 10 is provided with the same wind speed sensor 11, and the wind speed sensor 11 is installed on the top of the inner cavity of the frame 8, and the operating status of the equipment is monitored by the wind speed sensor 11, and then the electric heating plate 10 is used to heat and heat the filter screen 9 to achieve the effect of sterilizing the filter screen 9.
