Vertical type air purifier with noise-reducing structure

Abstract

The invention discloses a vertical type air purifier with a noise-reducing structure. The vertical type air purifier comprises a housing, wherein an air inlet part, a fan part and an air outlet part are sequentially arranged in the housing from bottom to top; the housing is provided with a top opening, and an air outlet cover plate covers the opening; the air outlet cover plate can ascend upwards,and can descend and drop to the original position; when the air outlet cover plate upwards ascends, the lower portion of the air outlet cover plate and the top opening of the housing define an air outlet; and ascending height, along with the air outlet cover plate, of the air outlet is increased or reduced. The vertical type air purifier is adjustable in size of the air outlet, saves energy and reduces noises, is convenient to use, and is high in purifying efficiency.

Description

technical field [0001] The invention belongs to the technical field of air purification equipment, and in particular relates to a vertical air cleaner with a noise reduction structure. Background technique [0002] With the improvement of people's living standards and the emphasis on the air environment, the market demand for air purifiers is growing rapidly. Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness. Among them, the principle of the filter air purifier is that the air enters from the air inlet, passes through the filter screen, the air duct, and then blows out from the air outlet. [0003] The existing vertical air cleaner also has the following deficiencies: [0004] (1) The limitations of the design...

AI Technical Summary

Problems solved by technology

[0004] (1) The limitations of the design of the air inlet structure lead to the inability of the filter element to be fully utilized: in order to improve the efficiency of the air inlet, in the prior art, air inlets are set on the four side walls of the air purifier housing, or the air inlets are arranged densely. The wind hole, the former method of setting the air inlet, because the air inlet is larger and placed below the side wall of the casing, it will affect the structural strength of the casing, making the overall structure unstable and firm, and the latter setting the air inlet fine hole In the way of long-term use, the fine and dense holes are difficult to clean and easy to block, which hinders the air intake; therefore, in the prior art, considering the structural strength of the shell, several long grooves symmetrically arranged on both sides of the shell are usually designed. The gap is used as the air inlet. The disadvantage of this is: because the filter element of the vertical air purifier is mostly ring-shaped, after long-term use, the most wind-receiving surface of the ring-shaped filter element is only near the air inlet, and the rest are not directly close to the air inlet. The local filter material is not fully utilized;

[0005] (2) The size of the air outlet cannot be adjusted, resulting in dust and noise entering the air outlet: In the prior art, the air outlet of the air purifier is mostly designed as an open structure, which is easy to fall into dust after long-term use. In addition, the air purifier The air inlet speed is adjustable, but the size of the air outlet cannot be changed accordingly. As a result, when the air inlet speed is high, the noise of the air outlet is large, which affects the comfort of use.

But it can't. It has great limitations in noise reduction and can't apply to a variety of wind forces.
