Description

Fan Fixture and have the casing of this fan Fixture

Technical field

The present invention relates to the fixing and dust control technology of fan, particularly a kind of casing that makes things convenient for the fan Fixture of the fixing and dustproof effect of tool of fan and have this fan Fixture.

Background technology

General computer housing is the heat dissipation that reaches good; usually can fan be set in inside; utilizing fan air outside to be sucked and makes the therefore exchange of the inner and extraneous air of casing, and then solve the problem that casing inside causes part life to shorten because of accumulation of heat.

And general fan utilizes screw directly it to be locked on the madial wall of casing usually, therefore the dust of casing outside can directly be sucked into casing inside by the louvre on the casing, especially insect can be invaded in the casing by louvre especially, and the intrusion of this dust and insect is easy to cause the fault of casing embedded computer system, and has influence on the serviceable life of casing internal electrical components.

For addressing the above problem, the part computer housing then has additional dustproof filter screen in addition with anti-dust and insect, is that 274558,381742 utility model patent and application number are 200320119076.3 the disclosed dustproof or filtration unit of Chinese utility model patent as the TaiWan, China notification number.Though those dustproof or filtration units have the effect of anti-dust and insect, and it has interchangeable structure, because those filtration units are comparatively complicated with the corresponding fixed sturcture of its fan, and the inconvenience that therefore still can cause assembling, replacing and clear up.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of fan Fixture that makes things convenient for the fixing and dustproof effect of tool of fan, and a kind of casing with this fan Fixture is provided.

Fan Fixture of the present invention comprises a pedestal, a lid and a filter screen, and wherein, pedestal has a groove chamber and supplies a fan is set, and has an insertion mouth and an air intake vent on the two adjacent sides of groove chamber respectively, and this air intake vent air feed fan sucks extraneous air; Lid is incorporated on the pedestal separably, so that fan is fixed in the groove chamber, and has several air outlets on the lid for discharging air; Filter screen can be inserted in the groove chamber of pedestal, to cover air intake vent by inserting mouth.

The said fans fixed mount can be assembled in the housing of a casing, and this filter screen can insert from a loam cake that is placed on housing, and is inserted in the groove chamber of pedestal by inserting mouth; One side of filter screen has two relative fins and supplies to cover the perforation of loam cake, and has a recess respectively on this two fin.

Said machine casing is because be assembled with this fan Fixture, so it is quick that fixing of fan comparatively made things convenient for, and also can prevent the intrusion of dust or insect by filter screen.This extraction-type filter screen can directly be extracted by outside and need not to open loam cake, and is therefore also considerably convenient in cleaning.In addition, on cover the extraction that the perforation with larger aperture can make things convenient for filter screen, two fins on this filter screen can prevent that then dust from being invaded by perforation.

Embodiment

See also Fig. 1, Fig. 2, first preferred embodiment of the present invention shown in the figure wherein discloses a fan Fixture 2, comprises a pedestal 20, a lid 30 and a filter screen 40.

Pedestal 20 has a groove chamber 21 for a fan 5 is set, and has one on the two adjacent sides of groove chamber 21 respectively and inserts mouthful 22 and one air intake vent 23, and air intake vent 23 air feeds fan 5 sucks extraneous air.Have a button hole 24 on the two opposite sides cell wall of groove chamber 21 respectively, and the electric wire 51 that also has a short slot 25 air feeds fan 5 therein on the cell wall of a side passes.

Lid 30 is located in the groove chamber 21 of pedestal 20, and has 5 settings of a room 31 air feeds fan.Room 31 has several air outlets 32 for discharging air over against the middle position of the bottom surface of fan 5, falls to locating then to be respectively equipped with a fixed leg 33 for being embedded in the fixed orifice 52 of fan 5 at two relative angles.Fixed leg 33 has a lead angle 330 and several grooves 331, and lead angle 330 is formed at the ora terminalis of fixed leg 33, in order to fixed leg 33 is guided in the fixed orifice 52 of fan 5.Groove 331 connects the opposite flank of fixed leg 33, and opening-like so that fixed leg 33 has elastic deformation force radially at ora terminalis.The dual-side of lid 30 is respectively equipped with a button hook 34, and button hook 34 has the elastic deformation force, is located in the button hole 24 of pedestal 20 for detaining separably.

Filter screen 40 can be inserted in the groove chamber 21 of pedestal 20 by inserting mouth 22, to cover this air intake vent 23.One side of filter screen 40 has relatively and is inclined upwardly and is two fins 41 of circular arc, has a recess 42 on two fins 41 respectively, is convenient to user's finger and stretches into to extract filter screen 40.

As shown in Figure 3, have a flange 26 respectively near air intake vent 23 places on the two opposite side walls of groove chamber 21, lid 30 is resisted against flange 26.When fan 5 was fixed in

groove chamber

21,23 of fan 5 one sides and air intake vents formed a space 260 so that filter screen 40 to be set, and were extended with a wind deflector 27 in that a side of air intake vent 23 is also outwards oblique, so that fan 5 sucks more air.

In Fig. 3, can find out, but button hook 34 elastics wings of lid 30 both sides, for cramping distortion and button is located in the button hole 24 of pedestal 20 and lid 30 is incorporated on the pedestal 20.Otherwise then can again button hook 34 crampings be out of shape button hole 24, and make lid 30 by breaking away from the pedestal 20 with disengaging pedestal 20.

As shown in Figure 4, the limit, two opposite sides of air intake vent 23 convexes with an architrave 28 respectively, and architrave 28 1 ends extend to and insert mouth 22, and has a location protuberance 280 on architrave 28.The both side edges of filter screen 40 1 sides respectively has a location recess 43 and can be embedded for positioning convex portion 280, so that filter screen 40 has the preferred positioning effect.

See also Fig. 5, second preferred embodiment of the present invention shown in the figure, it is one to have the casing of said fans fixed mount 2; Wherein, this casing comprises a housing 1, a loam cake 11 and this fan Fixture 2.Housing 1 one sides 10 have several through holes 13 and communicate with the inside of housing 1.Loam cake 11 is covered on the housing 1, and through hole 13 places that loam cake 11 is close to housing 1 have a jack 14 and a perforation 15.Jack 14 is strip, the centre that jack 14 is located in perforation 15, and greater than the width of jack 14.

In addition, fan Fixture 2 utilizes pedestal 20 and is fixed in the inside of housing 1, and makes the through hole 13 of the air intake vent 23 of pedestal 20 towards housing 1, so that fan 5 can suck extraneous airs by several through holes 13 by air intake vent 23.Filter screen 40 can insert from the jack 14 of loam cake 11, and is inserted in the groove chamber 21 of pedestal 20 by inserting mouth 22, to cover air intake vent 23.

As shown in Figure 6, filter screen 40 is inserted by the jack 14 of loam cake 11, and through inserting mouthfuls 22 and when being inserted in pedestal 20, two fins 41 of filter screen 40 sides cover the perforation 15 of loam cake 11, can prevent that dust from being invaded by perforation 15.

So, because lid 30 can be incorporated on the pedestal 20 by the flexible button hook 34 of tool, can make the dismounting of fan 5 more convenient fast, and the filter screen 40 on the fan Fixture 2 can effectively prevent dust or insect intrusion.By removable filter screen 40, the veil that the user need not to open loam cake 11 or moves any covering fan 5 can be directly by housing 1 outside the extraction, and therefore, filter screen 40 is also suitable convenience in cleaning.In addition, the perforation 15 of larger aperture can make things convenient for the extraction of filter screen 40 on the loam cake 11, and two fins 42 on the filter screen 40 can prevent effectively that then dust or foreign matter are by perforation 15 intrusions.
