Based on the above-described embodiments, the technical problem that the present application intends to solve is how to extend the service life of the rotor 3b 2. For this reason, the present application achieves the function of protecting the rotor 3b2 through the fourth mount 1 a. Through a plurality of baffles 1a1, sundries with larger volume can be prevented from entering the heating, ventilating and air conditioning filter, so that the filter screen 2b is blocked, and through the arrangement of the baffles 1a1, the rotor 3b2 can be protected, and the condition that other objects are contacted with the rotating rotor 3b2, so that the rotor 3b2 is damaged is prevented.
Further, the present application still has the defect that the box 5a is not tightly combined with the rack 1, which causes air leakage and affects the use efficiency of the heating, ventilation and air conditioning, and in order to solve the problem, as shown in fig. 9:
the frame 1 comprises a sealing ring 1b, and two surfaces of the sealing ring 1b are respectively fixedly connected with the frame 1 and the box body 5 a.
Based on the above embodiments, the technical problem that the present application intends to solve is how to prevent the air flow from leaking. For this reason, this application has realized improving the function of heating and ventilating air conditioner filter leakproofness through sealing washer 1 b. The sealing ring 1b is preferably made of rubber materials, the sealing performance of the joint of the frame 1 and the box body 5a can be greatly improved through the elasticity of the sealing ring 1b, and impurities and viruses are further prevented from entering an air-conditioning pipeline while air current leakage is prevented.
The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
