Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description of a preferred embodiment of following conjunction with figs., can clearly present.
Consult Fig. 3, a preferred embodiment of the image sensing module that the present invention is air-escaped comprises pedestal 2, image sensing unit 3, filter 4 and two and escapes gas unit 5.
This pedestal 2 comprise vertical optical axis L the first gluing face 21, with the second gluing face 22 of these first gluing face, 21 opposing settings, and the hollow area 23 that connects this first and second gluing face and offer along this optical axis L.
This image sensing unit 3 is cemented in this first gluing face 21.
This filter 4 is cemented in this second gluing face 22.
Consult Fig. 3 and Fig. 4, this is escaped on the second gluing face 22 that gas unit 5 is positioned at this pedestal 2, comprise respectively be communicated with first of this hollow area 23 escape gas inlet 51 and second escape gas inlet 52, is communicated with extraneous escape gas outlet 53, be communicated with this first and second escape gas inlet 51,52 and escape gas export 53 escape gas passage 54, reach stopper 55.
In order to omit the processing procedure of mending glue sealing and slaking viscose, seal so in this preferred embodiment, this can't be escaped gas outlet 53, therefore, this is escaped gas unit 5 and must have concurrently and escape gas and dustproof effect.
This escapes gas passage 54 perpendicular to this optical axis L setting, because dust is easier on the direction of parallel this optical axis L to flow, is designed to vertically this optical axis L and is provided with and prevents that with helping dust from entering this hollow area 23 so this is escaped gas passage 54.
In addition, be able to that by Fan Dewaerli dust is adsorbed in each and escape gas passage 54, so with each escape gas passage 54 be designed to be tortuous labyrinth-like ground be communicated with each first and second escape gas inlet 51,52 and escape gas and export 53, increase dust and each are escaped the contact area of gas passage 54, help to delay dust and enter this hollow area 23, the influence that allows this image sensing module be subjected to the dust invasion in service life drops to minimum.
Consult Fig. 5, what illustrate further is, this cross section of escaping gas passage 54 is thin-and-long, and this escapes gas passage 54 and be not more than 0.05mm along the gap width of this optical axis L, by this, the energy blocking diameter is greater than the dust of 0.05mm, and diameter is lighter less than the dust weight of 0.05mm, can be adsorbed in this by Fan Dewaerli and escape in the gas passage 54, more preferably, gap width in this preferred embodiment is between 0.02～0.03mm, hinders the effect that dust enters so that more improve.
Consult Fig. 4 and Fig. 5, and in this preferred embodiment, each escape gas passage 54 have connect this first escape first entrance 541 of gas inlet 51, bendingly be communicated with first turn section 542 of this first entrance 541, be communicated with escaping gas outlet section 543, connecting this and second escape second entrance 544 of gas inlet 52 of this first turn section 542 bendingly, and extend to second turn section 545 that this escapes gas outlet section 543 bendingly from this second entrance 544.
Each second entrance 544 and second turn section 545 are to be symmetrical arranged with each first entrance 541 and first turn section 542 respectively.
Each stopper 55 is to be centered on by each first and second turn section 542,545 and first and second entrance 541,544 to define.This stopper 55 is used to slow down the impulse force that extraneous dirty air flows into this hollow area 23, increases the degree of difficulty that dust enters.
What deserves to be mentioned is, this air-escaped image sensing module also can comprise quantity be one or greater than two escape gas unit 5, only comprise one and escape gas unit 5 and also can reach air-out and prevent that dust from entering the effect of this hollow area 23, can avoid overflowing the glue passage and have influence on and escape gas, dustproof effect if comprise a plurality of 5 of gas unit of escaping.
In sum, because this is escaped gas passage 54 and is perpendicular to this optical axis L setting, possessed the effect that stops that dust enters, further, this is escaped, and gas passage 54 is tortuous labyrinth-like design and the cross section is very narrow, increase the area of absorption dust, and weaken the impulse force that dirty air flow into by this stopper 55, therefore, this is escaped gas unit 5 and possesses exhaust and stop dirty double effects, and then omit the processing procedure of mending glue sealing and slaking viscose, so can reach purpose of the present invention really.
The above only is preferred embodiment of the present invention, can not limit scope of the invention process with this, and promptly all simple equivalent of being done according to claim of the present invention and invention description content change and modify, and all still belongs in the scope that patent of the present invention contains.
