Description

Have the domestic electric fan of air-cleaning function concurrently

Technical field

The utility model relates to air conditioning, relates in particular to the ventilation equipment of forced air flow, particularly relates to the domestic electric fan that has air-cleaning function concurrently.

Background technique

Prior art domestic electric fan low price, easy to use, realizes ventilation, for people, enjoys the cool by its forced air flow.In recent years, along with industrialization makes progress rapidly, atmospheric pollution aggravation, people more and more pay close attention to air quality, and have had higher requirement.For meeting this class demand, on market, there are various special-purpose air purified product, what wherein quantity was maximum is the air cleaner of HEPA type.

HEPA i.e. " high efficiency particulate air filters ", it is the abbreviation of High efficiency particulate air Filter, it up to more than 99.97%, is the most effective filtering mediums of pollutant such as smog, dust and bacterium to the above particle removal efficiency of 0.3 micron of diameter (hair diameter 1/200).HEPA comprises PP filter paper, glass fibre, compound PP-PET filter paper, melt and spray-terylene non-woven fabric and melt and spray-five kinds of materials such as glass fibre, be characterized in: windage is little, dust containing capacity is large, filter precision is high, on market, easily bought, can need to be processed into various sizes and shape according to client, be applicable to different types and use.

The forced air flow during work of described air cleaner inner blower assembly, makes air-flow pass through HEPA, and the solid grain contamination in air-flow is held back by HEPA and adsorbed, so what blow out is the air being cleaned.Obviously, if need to ventilate, enjoy the cool, need again to purify air, just must buy two equipment, not only spend more money, more than take up room.

Model utility content

The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of domestic electric fan that has air-cleaning function concurrently is provided, in the air outlet mesh outside of prior art domestic electric fan, install removable air filtering assembly additional exactly.Simple in structure, with low cost, and easy to use.

The utility model solve the technical problem the technological scheme of taking: design a kind of domestic electric fan that has air-cleaning function concurrently, comprise that fuselage and level are assemblied in the head at its top, and the base that is bound up on fuselage bottom, described head front portion is air outlet mesh and accommodating impeller in the inner, rear portion is the motor that drives this vane rotary, and described head and its included guard, impeller and drive motor thereof have common central axis; Especially:

Described guard outer surface is installed the filter assemblies for purifying air removedly, comprise the framework with described guard excircle configuration radial adaptation, this framework is the trellis work of hollow out just above, and its inner face is installed filter screen removedly, and the raw wind of described vane rotary blows out through described filter assemblies.

Further, the radially excircle configuration of described guard, stretches and becomes clitellum shape net circle slightly backward vertically; Correspondingly, the radially external frame of described framework should be also cylndrical surface, on its excircle, evenly arrange that axially stretch backward at least two places, in order to the pawl of buckleing with the clamping of described net circle.

Further, described filter screen is layer structure and/or the fibrous structure of high efficiency particulate air filters HEPA type.

Further, in described base or fuselage, control unit is set.

Compared with prior art, the beneficial effect that the utility model has the domestic electric fan of air-cleaning function concurrently is:

1, by installing filter assemblies additional, the dual function that makes domestic electric fan possess blowing and purify air;

2, filter assemblies is designed to removable structure, when not needing to purify air, can remove filter assemblies and not affect the original blowing function of electric fan, easy to use;

3, the framework that filter assemblies comprises can be separated with filter screen, convenient for cleaning and/or replacing filter screen.

Accompanying drawing explanation

Fig. 1 is the overall appearance axonometric projection schematic diagram of the utility model domestic electric fan preferred embodiment of having air-cleaning function concurrently;

Fig. 2 is the exploded structural representation of Fig. 1, but has only decomposed filter assemblies 50;

Fig. 3 is the exploded structural representation of exploded view 1 air-out, the working principle that purifies air.

Embodiment

Below in conjunction with each accompanying drawing, content of the present utility model is described in further detail.

Shown in Fig. 3, have the domestic electric fan of air-cleaning function concurrently, comprise that fuselage 10 and level are assemblied in the head 20 at its top, and the base 30 that is bound up on fuselage 10 bottoms, the interior control unit 31 that arranges of base 30 or fuselage 10.Head 20 front portions are air outlet mesh 21 and accommodating impeller 22 in the inner, and rear portion is the motor 40 that drives these impeller 22 rotations, and head 20 and its included guard 21, impeller 22 and drive motor 40 thereof have common central axis; Guard 21 outer surfaces are installed the filter assemblies 50 for purifying air removedly, comprise the framework 51 with guard 21 excircle configuration radial adaptation, this framework 51 is the trellis work 510 of hollow out just above, its inner face is installed filter screen 52 removedly, filter screen 52 is layer structure and/or the fibrous structure of high efficiency particulate air filters HEPA type, and the raw wind of impeller 22 rotation after filtration assembly 50 blows out.

As shown in Figure 2, the radially excircle configuration of guard 21, stretches and becomes clitellum shape net circle 210 slightly backward vertically; Correspondingly, the radially external frame of framework 51 should be also cylndrical surface, on its excircle, evenly arrange that axially stretch backward at least two places, in order to the button pawl 511 with 210 clampings of net circle.

During electric fan work, the raw wind of impeller 22 rotation blows out through filter screen 52, reaches the object purifying air.While not using electric fan, the button pawl 511 that can get loose, takes off filter assemblies 50.

Button pawl 511 is set on framework 51, is used for carrying out detachable clamping with clitellum shape net circle 210.Also can use the modes such as elastic hook, elastic bands that filter assemblies 50 is removably mounted in to outside, exhaust outlet front, wherein filter screen 52 can be various ways, here preferred HEPA filter screen.All the other each component of fan belong to prior art, so locate to repeat no more.
