Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation ducts, and in particular relates to a dustproof air outlet. Background Art

[0002] Ventilation duct is the abbreviation of ventilation pipe, which is a metal or non-metallic pipe used in ventilation and air-conditioning engineering of industrial and civil buildings. Ventilation duct is a kind of municipal infrastructure for air circulation and reducing the concentration of harmful gases. The air outlet of ventilation duct is an important part of ventilation duct, which is fixed on the ventilation duct to realize ventilation function.

[0003] At present, most air outlets are exposed to the outside, or are designed in the form of shutters. Although they can meet the ventilation function, the dust prevention effect is poor. Dust from the outside can easily enter and accumulate in the air outlet, which can easily breed bacteria over time and affect the air quality.

[0004] To solve the above problems, it was retrieved from the prior art that a Chinese utility model patent with authorization announcement number CN220624287U disclosed "a green building design energy-saving ventilation structure", including a wall with ventilation holes on the surface of the wall; a ventilation duct arranged on the inner wall of the ventilation hole; a mounting plate fixedly arranged on the surface of the ventilation duct, with fixing bolts on the surface of the mounting plate; the mounting plate and the wall are connected by fixing bolts; a dustproof mechanism is arranged inside the ventilation duct, and an adjustment mechanism is arranged inside the ventilation duct. By pulling the handle and pulling out the dust filter with the cooperation of the sliding bar, the dust attached to the front and back sides of the dust filter will be brushed off by the brush arranged on the fixed seat and fall into the collection box.

[0005] Although the ventilation structures in the prior art including those mentioned above have dust-proof effects, in actual use, it is troublesome to pull the dust filter to clean the dust, and the collection box cannot reliably collect the dust. This is because if the collection box is too close to the dust filter, the dust on the dust filter is easily brushed off by the collection box, which is not conducive to collection. On the contrary, if there is a gap between the collection box and the dust filter, dust is easy to fall out of the gap, which is also not conducive to collection.

[0006] In order to solve the above problems, the present application proposes a dust-proof air outlet. Utility Model Content
