Description
Technical field：
The invention belongs to sensor guard technical field, more particularly, to a kind of sensor protection mechanism of waterproof and breathable.
Background technology：
Present increasing electronic product is harsh due to the market demand and working environment, and classification of waterproof requires more and more higher, especially
It is the electronic product of mobile phone, Intelligent bracelet, outdoor lighting monitoring and the balance car of outwork etc, is produced as this electron-like
The main component of product, also corresponding requirements are uprised the classification of waterproof of sensor.However, traditional waterproof project is largely using knot
Structure seals waterproof.The problem of sealing structure waterproof is present is a lot, such as, as ambient temperature changes, air pressure inside is therewith
Change, whole product can be shriveled or expanded, so as to cause structural damage；In addition, if internal wetly entrance, vapour molecule
Can be difficult discharge, internal electronic component is corroded, so that the service life of sensor declines.
The content of the invention：
The technical problems to be solved by the invention are：The sensor water-proof protection of a kind of achievable high temperature resistant and pressure release effect is provided
Mechanism.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of biography of waterproof and breathable
Sensor protection mechanism, including protective cover, sensor, base material and waterproof ventilated membrane, the sensor are placed in inside protective cover, and
It is connected and sealed between the sensor and protective cover by the first high temperature resistant waterproof glue, first is offered on the protective cover
The second air-vent is offered on air-vent, the base material, the top surface of the waterproof ventilated membrane is close by the second high temperature resistant waterproof glue
Envelope is fixedly mounted on the inwall of protective cover, and the high temperature resistant waterproof glue of underrun the 3rd and the base material of the waterproof ventilated membrane are sealed
It is fixedly mounted, the first air-vent of the protective cover is communicated with the second air-vent of base material, and the waterproof ventilated membrane is complete
Cover the first air-vent and the second air-vent.
Preferably, the waterproof ventilated membrane 4 is the E-PTFE thin-film materials after foaming, and the waterproof ventilated membrane 4
Reach 7 machine waterproof requirements.
Preferably, the diameter of second air-vent is more than the diameter of the first air-vent.
Preferably, the base material selects PI films or PI non-woven fabrics.
Preferably, the base material selects stainless steel substrates.
Compared with prior art, usefulness of the present invention is：Because the normal working environment of sensor is 260 DEG C and guarantor
Protective case inside and outside differential pressure by this structural defence sensor, can both be acted on high temperature resistant than larger, and can also reach the work of pressure release
With may also reach up 7 grades of waterproof purposes.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the top view of the present invention.
Fig. 2 is the sectional view of front view of the present invention.
Embodiment：
Below in conjunction with the accompanying drawings and embodiment the present invention will be described in detail：
A kind of sensor protection mechanism of waterproof and breathable as depicted in figs. 1 and 2, including protective cover 1, sensor 8, the and of base material 6
Waterproof ventilated membrane 4, the sensor 8 is placed in inside protective cover 1, and protective cover 1 plays integral protection effect to sensor 8, and
It is connected and sealed, is offered on the protective cover 1 by the first high temperature resistant waterproof glue 9 between the sensor 8 and protective cover 1
The second air-vent 7 is offered on first air-vent 2, the base material 6, the top surface of the waterproof ventilated membrane 4 passes through the second high temperature resistant
The sealing of marine glue 3 is fixedly mounted on the inwall of protective cover 1, the high temperature resistant waterproof of underrun the 3rd of the waterproof ventilated membrane 4
Glue 5 is sealed with base material 6 and is fixedly mounted, and base material 6 plays a part of strengthening the use intensity of waterproof ventilated membrane 4, the waterproof ventilated membrane 4
By the E-PTFE films for specially treated of foaming, there is thousands of a diameter of 0.1 μm~1 μm of micropore above, it is allowed to air and
Hydrone is freed in and out, but the globule and dust can be prevented to enter, and can be reached《Shell protection grade》7 grades of waterproofs will
Ask, the first air-vent 2 of the protective cover 1 is communicated with the second air-vent 7 of base material 6, and the waterproof ventilated membrane 4 is sealed completely
Lid the first air-vent 2 and the second air-vent 7；When the inner space of protective cover 1 due to temperature is raised and when causing air pressure to become big, in it
The second air-vent of portion's gas permeation 7, the air-vent 2 of waterproof ventilated membrane 4 and first overflow, to realize that the air pressure inside of protective cover 1 is balanced；
When the inner space of protective cover 1 causes air pressure to become big due to temperature rise, gas permeation waterproof ventilated membrane 4, first in air
The air-vent 7 of air-vent 2 and second is added to inside protective cover 1, to realize that the air pressure inside of protective cover 1 is balanced, in addition, waterproof and breathable
Film 4 realizes that existing process selects PET as diaphragm below it is necessary to have layer protecting film during automating than relatively thin,
Then PET protection film is removed again.Smaller yet with this physical dimension, automation goes PET protection film relatively difficult, so
Waterproof ventilated membrane 4 is sticked using being provided with the base material 6 of the second air-vent 7, then integrated automation punching press can both strengthen anti-
The intensity of water ventilated membrane 4, reduces deprotection Mo Zhe roads technique again.
As waterproof ventilated membrane 4 it is a kind of it is preferred prepare material, the waterproof ventilated membrane 4 is the E-PTFE films after foaming
Material, E-PTFE thin-film materials have the advantages that use intensity is high and resistance to elevated temperatures is strong, and the waterproof ventilated membrane 4 reaches
7 machine waterproof requirements.
The diameter of first air-vent 2 is about set to 1mm~2mm, in order to ensure enough Air permenbilities and reach that 7 grades are prevented
Water purpose, the diameter of second air-vent 7 is more than the diameter of the first air-vent 2.
As a kind of preferred material of the actual use of base material 6, the base material 6 selects PI films or PI non-woven fabrics, PI films or
Person's PI non-woven fabrics has excellent resistant of high or low temperature, electric insulating quality, caking property, radiation resistance, resistance to medium, can be -269
DEG C~280 DEG C within the temperature range of be used for a long time, 400 DEG C of high temperature is can reach in short-term, therefore waterproof ventilated membrane 4 can be effectively improved
Use intensity and service life.
As another preferred material of the actual use of base material 6, the base material 6 selects stainless steel substrates, and stainless steel substrates are anti-
On the basis of the use intensity of water ventilated membrane 4, have the advantages that cost is low.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not make any formal to the present invention
Limitation, any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
In the range of still falling within technical solution of the present invention.
