Description

A new fan of air purification for dining room

Technical Field

The utility model relates to an air purification device, concretely relates to new fan of air purification for dining room.

Background

At present, with the improvement of living standard, more and more people have dinner in a restaurant, and CO in the restaurant₂The content is relatively large, the humidity in the air is high, and various odors are mixed; the variety of indoor kitchens, public toilets and various functional rooms is more, and the number of pollution sources such as bacteria, viruses and the like in the air is greatly increased; in addition, in order to improve the heating effect in winter and the refrigerating effect of an air conditioner in summer, the opening rate of doors and windows is low, the air circulation is poor, and a fresh air system becomes indispensable.

Air quality has become an increasingly important issue for restaurants. Needless to say, fresh and smooth air brings a feeling of relaxed and happy mind and excitement, while stagnant and hot air brings a reason of no essence, unconsciousness and sleep, and the flow of air around a human body can promote the evaporation of body fluid to play a role of natural cooling, thereby avoiding uncomfortable reactions caused by poor ventilation such as sultry, peculiar smell, dust, oil smoke and the like.

At present, a restaurant fresh air system mostly adopts a pure ventilation system, indoor outdoor air is not purified and directly enters a restaurant, the fresh air quality is limited by the outdoor air quality, and the outdoor air quality often has many problems. Therefore, it is important to purify outdoor air to be introduced into a room before the outdoor air is introduced into the room while ventilating.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 4, the present embodiment includes a housing 1, the housing 1 is a hexahedral structure and includes four side surfaces 11, a top surface 12 and a bottom surface 13, the first side surface 111 is provided with an air inlet 2, and the third side surface 113 is provided with an air outlet 3.

A first air guide hopper 81, a primary filter screen 4, an air blower 5, an activated carbon filter screen 6, a PM 2.5 particle filter screen 7 and a second air guide hopper 82 are sequentially arranged in the shell 1 from the air inlet 2 to the air outlet 3.

Primary filter screen 4, active carbon filter screen 6 and PM 2.5 granule filter screen 7 are fixed between top surface 12 and bottom surface 13 of casing 1, and the fixed department is equipped with draw-in groove 9, can take the filter screen out easily in casing 1, are convenient for wash and change.

The primary filter screen 4 is made by folding white non-woven fabrics, after the folding part is unfolded, the area is enlarged by several times to show the front of eyes, and the filter area is large enough.

The activated carbon filter layer 6 is formed by irregularly assembling a plurality of graphite-type microcrystalline with a layered structure, can effectively purify indoor air, and can adsorb peculiar smell, toxic and various harmful gases in the air, particularly formaldehyde, benzene series, TVOC, CO and NH in the air₃、O₃、Cl₂Etc. have unique adsorption, purification and catalysis capabilities.

PM 2.5 granule filter screen 7 adopts the polypropylene material, through the interaction force between fine particles and the filter screen, filters the particulate matter that the diameter is below 0.1 um.

Air-blower 5 sets up between primary filter screen 4 and active carbon filter screen 6, and outdoor air passes through air-blower 5 and does work, from air intake 2 entering casing 1 in, through primary filter screen 4 under the effect of wind force, large granule dust and the worm that can effectively filter among the air get into in the casing.

One end of the air guide hopper 8 is a mounting opening 811, and the other end is an air opening 812, so that the funnel-shaped design of the air guide hopper can convey air more efficiently.

One end of the first air guide hopper 81 is connected with the air inlet 2 and fixed on the inner wall of the first side surface 111, and the other end is attached to the primary filter screen 4; one end of the second air guide funnel 82 is connected with the air outlet 3 and fixed on the inner wall of the third side 113, and the other end is attached to the PM 2.5 particle filter screen 7.

The outdoor air entering from the air inlet 2 passes through the first air guide hopper 81, then sequentially enters the primary filter screen 4, the activated carbon filter screen 6 and the PM 2.5 particle filter screen 7 under the action of the air blower 5, and then enters the air outlet 3 through the second air guide hopper 82, and the outdoor air is sent into the room.
