Group is internal, and more than 80% air is entered in module by below the side of the camera module after the filter element filtration described in
Portion.
Optionally, the filter element is located at the camera module at least 1/2 level above position.
Optionally, the dustproof element making circular hole.
Optionally, after the camera module is assembled with cell phone rear cover plate, the filter element is protruded from after the mobile phone
The surface of cover plate.
Optionally, the dustproof element and the filter element are wholely set.
Optionally, the dustproof element and the filter element are made up of hydrophobic material.
Optionally, the dustproof element is made up of rubber, and the filter element is made up of foam.
Optionally, the dustproof element and the filter element are made up of fluorine material.
Optionally, the barrel unit of the camera module is fitted with the dustproof element, filter element, the lens barrel list
It is first with the dustproof element, the contact surface of filter element on lubricant coating is set, reduce frictional force when barrel unit is moved.
Optionally, the lubricant coating is fluorine material.
Relative to prior art, the dust-control method of the camera module of the present invention at least has the advantages that：
In the present invention, in the camera module top arrange dustproof element, filter element so that less than 20% air by
The top of the camera module enters module internal, and more than 80% air is by Jing institutes below the side of the camera module
State after filter element is filtered and enter module internal, so as to realize the dust reduction capability of camera module.
Description of the drawings
Fig. 1 is the structural representation of camera module in one embodiment of the invention.
Specific embodiment
Elaborate many details in order to fully understand the present invention in the following description.But the present invention can be with
Much it is different from alternate manner described here to implement, those skilled in the art can be in the situation without prejudice to intension of the present invention
Under do similar popularization, therefore the present invention is not embodied as being limited by following public.
Secondly, the present invention is described in detail using schematic diagram, when the embodiment of the present invention is described in detail, for purposes of illustration only, institute
It is example to state schematic diagram, and its here should not limit the scope of protection of the invention.
In in order to solve the problems, such as background technology, the present invention in, in the camera module top arrange dustproof element,
Filter element so that less than 20% air enters module internal by the top of the camera module, more than 80% air by
The side lower section of the camera module enters module internal after filter element is filtered described in, so as to realize camera module
Dust reduction capability.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, below in conjunction with accompanying drawing to the present invention
The dust-control method of camera module be described in detail.
With reference to shown in Fig. 1, the camera module of the present invention includes flexible PCB（FPC）1st, on flexible PCB 1
Imageing sensor 2, the barrel unit 3 on imageing sensor 2, between flexible PCB 1 and imageing sensor 2 by gold
Line is electrically connected with, and barrel unit 3 is fixed on imageing sensor 2 by bracing frame.
With continued reference to shown in Fig. 1, dustproof element 4, filter element 5 are set in the top of the camera module.Specifically,
Dustproof element 4 and filter element 5 are separately positioned on the side of barrel unit 3, and the dustproof element 4 and the filter element 5
The setting of one.Also, the barrel unit 3 of the camera module is fitted with the dustproof element 4, filter element 5, the mirror
Lubricant coating is set on cylinder unit 3 and the dustproof element 4, the contact surface of filter element 5（Not shown in figure）, reduce lens barrel list
The frictional force produced with dustproof element 4, filter element 5 when unit 3 moves.In the present embodiment, the lubricant coating is fluorine material,
For example, made using politef.
Additionally, the filter element 5 is located at the height and position of the camera module at least more than 1/2, by the shooting
After head mould group is assembled with cell phone rear cover plate, the filter element 5 protrudes from the surface of the cell phone rear cover plate.Additionally, described anti-
Circular port is offered on dirt element 4, is easy to the connection with barrel unit 3.
In the present invention, dustproof element 4 and filter element 5 are used to that a small amount of air to be entered from the top of camera module
