Abstract

The utility model mainly provides a tower fan with a filter screen, which comprises a pair of front and rear casings, fan blades and a base; wherein, the front and the rear machine shells are respectively provided with a fence-shaped air outlet and an air inlet; the outer side of the air inlet of the rear shell is provided with a movable filter screen; therefore, when the outside air passes through the filter screen and is sucked into the tower fan from the air inlet, the filter screen can generate a filtering effect, so that the effects and advantages of blocking dust and foreign matters in the outside air and easily cleaning the filter screen are achieved.

Description

Tower fan with filter screen

Technical field

The utility model relates to a kind of tower fan with filter screen, and particularly a kind of tower fan structure of the intake grill arranged outside filter screen in the tower fan mainly has the dirty air of filtration, avoids extraneous dust to be inhaled into tower fan advantage and effect inner and that clean easily.

Background technique

General vertical tower fan structure is made of the vertical flabellum of a pair of forward and backward casing, one group of casing inside and the base of bottom, wherein, for making air draught can brush transmission smoothly, so be respectively equipped with exhaust outlet and intake grill on the forward and backward casing like palisade shape, utilize the rotation of inner flabellum and can make the extraneous air of tower fan be inhaled into tower fan inside, outwards blow by the exhaust outlet of front housing again by the flabellum rotation from the intake grill of back cabinet.Fan at tower through the inventor and to find after actual user mode examines, tower fan flabellum surface attaches dust and other foreign matter easily, at the forward and backward casing that adds the tower fan is to adopt the combination of locking mode, disassemble and assemble all very inconvenience, therefore have a large amount of dusts of flabellum surface sediment and reach problems such as not easy to clean, and cause user's very big puzzlement.

Summary of the invention

The purpose of this utility model is for a kind of tower fan with filter screen being provided, mainly having the dirty air of filtration, avoiding extraneous dust to be inhaled into tower fan advantage and effect inner and that clean easily.

The inventor reaches to show purpose and design a kind of tower fan with filter screen, and this tower fan comprises a pair of forward and backward casing, flabellum and a base; Wherein, offer exhaust outlet and the intake grill that is palisade shape on the forward and backward casing respectively; It is characterized in that: establish in the intake grill outside of back cabinet has a movable filter screen, mat it, be inhaled into the tower fan when inner from intake grill again when air sees through filter screen, this filter screen can produce filtering effect, reach the dust and the foreign matter that cause in the obstruct ambient air, and easy effect and the advantage of cleaning of filter screen.

Above-mentioned tower fan with filter screen, wherein, this back cabinet is can an one-body molded slot, this slot is the outside that is positioned at intake grill, between this slot and the intake grill be to form a containing space of planting for filter screen, and the wall of this slot is to form a large amount of open-works.

Above-mentioned tower fan with filter screen, wherein, this back cabinet is the enclosing cover that can lock, this enclosing cover is the outside that is positioned at intake grill, between this enclosing cover and the intake grill be to form a containing space for the filter screen setting, and the wall of this enclosing cover is to form a large amount of open-works.

Description of reference numerals: 1 front housing; 11 exhaust outlets; 2 back cabinets; 21 intake grills; 22 slots; 221 open-works; 23 filter screens; 24 enclosing covers; 241 open-works; 3 flabellums; 4 bases.

Embodiment

See also first embodiment shown in Fig. 1 and 2, tower fan of the present utility model comprises a pair of forward and backward casing 1,2, flabellum 3 and a base 4; Wherein:

Offer exhaust outlet 11 and the intake grill 21 that is palisade shape on the forward and backward casing 1,2 respectively; And these back cabinet 2 outsides are one-body molded slots 22, and this slot 22 is the outsides that are positioned at intake grill 21, between this slot 22 and the intake grill 21 be to form a containing space, and the wall of this slot 22 are to form a large amount of open-works 221; And this slot 22 is to plant wherein for the movable filter screen 23 of a slice.

Use setting, when tower fan running air-supply, the ambient air at tower fan rear will pass the open-work 221 of slot 22 cell walls and the filter screen 23 in the slot 22 earlier, thus, the air that is inhaled into will filter through filter screen 23 earlier and dust in air and foreign matter be intercepted and long-pending investing on the filter screen 23, and it is inner only to allow that the intake grill 21 of peace and quiet air by back cabinet 2 after the filtration enters the tower fan, and the exhaust outlet 11 that sees through front housing 1 more externally blows.

Moreover, after the tower fan uses a period of time, cause filter screen 23 surface areas attached to a certain degree dust and during foreign matter, the user just can directly detach filter screen 23 slot 22 and be cleaned, treat just can again it be inserted in the slot 22 after dust on the filter screen 23 and foreign substance cleaning finish, can bring into play filtering function once again.

Next see also the utility model second embodiment, as shown in Figure 3, the tower fan that the utility model second embodiment is provided comprises a pair of forward and backward casing 1,2, flabellum 3 and a base 4 equally; Wherein:

Offer exhaust outlet 11 and the intake grill 21 that is palisade shape on the forward and backward casing 1,2 respectively; And these back cabinet 2 outsides are locking one enclosing covers 24, this enclosing cover 24 be inner concavity and and be to form a containing space that is provided with for filter screen 23 between the intake grill of back cabinet 2, and the wall of this enclosing cover 24 also forms a large amount of open-works 241:

Use setting, make filter screen can bring into play filtering function equally, and only need enclosing cover is unloaded, then have convenient effect of cleaning filter screen equally.

The above person, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, the i.e. equivalence of being done according to the utility model claim and model utility description generally changes and modifies, and all should still belong in the scope that the utility model patent contains.
