Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
Embodiment：As shown in figure 1, a kind of dust-protection type filter housing 1, including square box body 3 and the upper lid 2 of cooperation,
The upper bottom of lid 2, which caves inward, is provided with the first square neck 21, and the top edge of box body 3 is provided with cooperation first to lower recess and blocked
The groove 22 for having semi-cylindrical, the second neck 31 are horizontally disposed with second neck 31 of groove 21, each side wall of the first neck 21
Lateral wall on be provided with fit 22 semi-cylindrical fixture block 32, after upper lid 2 is downwardly against on box body 3, fixture block 32
Meeting inlay card is in neck, so as to reach the purpose of fastening box body 3 and upper lid 2.
As shown in Fig. 2 the bottom corner of box body 3 is respectively perpendicular the spring groove 4 for being extended and having cylindrical shape, the bottom of spring groove 4
Extended vertically on mediad in the gag lever post 41 for being provided with cylinder, spring groove 4 and be provided with the spring being set in outside gag lever post 41
42, spring 42 of CuZnAl memory alloy wires using being made, and this marmem has high-temperature-phase shape and low-temperature phase shape
Shape, low-temperature phase shape can be showed when in normal temperature, will change own form when in higher temperature to show high temperature
Phase shape, therefore the low-temperature phase of this spring 42 just can be set to be shaped as contraction state, high-temperature-phase is shaped as extended state, from
And realize purpose of the spring 42 by hot-stretch.
As shown in Figure 3,4, upper lid 2 be provided be equipped with the square radiating groove 5 of insertion, radiating groove 5 it is square close
Capping 6, the edge of closure 6 is surrounded with the sealing ring 62 for coordinating radiating groove 5, the upper table of 62 outer surface Self-sealed lid of sealing ring 6
Towards bottom angled, so as to facilitate the laminating radiating groove 5 of closure 6.The position difference of the bottom of closure 6 correspondence spring groove 4 is vertical
The motion bar 61 of cannula-like is provided with, the internal diameter of motion bar 61 is more than the internal diameter of spring 42, so as to play position-limiting action to spring 42.When
When closure 6 is snugly placed in radiating groove 5, the top of motion bar 61 is contacted with the bottom of spring groove 4, so as to closure 6
To supporting role.The top of spring 42 is connected with the lower surface of closure 6 with heat-resistant adhesive hydropexis.
Set as shown in figure 5, the bottom of radiating groove 5 is provided with the breathable films 51 for sealed heat-dissipating groove 5, breathable films 51
The through hole 52 for coordinating spring groove 4 is equipped with, the upper surface of spring groove 4 is with breathing freely when upper lid 2 is held on box body 3 as shown in Figure 3
The upper surface of film 51 is concordant.Insertion is provided with square air-vent 63 on closure 6, and the right flank of air-vent 63, which is fixedly installed, matches somebody with somebody
The bimetal leaf 64 of air-vent 63 is closed, bimetal leaf 64 is made up of two kinds of different metal materials of the coefficient of expansion, therefore when heated
When bimetal leaf 64 can be to the small curving of the coefficient of expansion, so that the small metal of the coefficient of expansion is located at into upper surface, just can be with
Bimetal leaf 64 is caused to deviate from air-vent 63 when realizing heated, while setting the temperature of the temperature distortion of bimetal leaf 64 to be less than
Spring 42, so as to realize that bimetal leaf 64 takes the lead in deforming.The surface of bimetal leaf 64 is fitted with sealing gasket 65, and the area of sealing gasket 65 is big
In air-vent 63, therefore when bimetal leaf 64 fits air-vent 63, sealed effect can be played.
Use process：Motion bar 61 on upper lid 2 is respectively cooperating with into corresponding gag lever post 41 to place, then firmly by upper lid
2 are pressed on box body 3, you can fixture block 32 is caught in groove 22, so as to realize the purpose of clamping box body 3.
When wave filter works, internal part can constantly produce heat, will make after heat reaches to a certain degree double
The underlying-metallic material of sheet metal 64 reaches deformation condition, therefore bimetal leaf 64 will be heated and outwards tilt, and now just make
Extraneous it must be more easy to contact with filter internal, the heat of filter internal can be dispersed into outside through relatively thin breathable films 51 are rapid
Boundary is gone, so that the effect for helping part cooling is reached, while breathable films 51 also can prevent extraneous dust from entering filter internal.
When temperature still rises while when reaching the deformation critical point of spring 42, spring 42 will be changed into his high-temperature-phase
Shape, i.e. extended state, so that spring 42 can be by the jack-up of closure 6 of top, the now extraneous communication with filter internal is more
Step up close, the further radiating effect for strengthening wave filter.
After wave filter is stopped, part will stop heating, so that filter temperature is gradually reduced, work as temperature
When reaching room temperature, spring 42 will reply the low-temperature phase shape of oneself, i.e. contraction state, and now closure 6 will come back to
In radiating groove 5, now the sealing ring 62 around closure 6 can be deformed by the extruding of radiating groove 5 and closure 6, so that
Obtain closure 6 to be brought into close contact with radiating groove 5, reach the purpose of sealing wave filter.It is simultaneously double on the air-vent 63 on closure 6
Sheet metal 64 can also recover normal condition, now the sealing gasket 65 on the surface of bimetal leaf 64 will the surface of gluing, sealing lid 6 again,
Reach sealed purpose.
