Height, especially mobile phone, Intelligent bracelet, outdoor lighting monitoring and outwork balance car etc electronic product, as this kind of
The main component of electronic product, also corresponding requirements uprise the classification of waterproof of sensor.However, traditional waterproof project is most of
Using sealing structure waterproof.The problem of sealing structure waterproof is present is a lot, such as, as ambient temperature changes, internal gas
Pressure changes therewith, and whole product can be shriveled or expanded, so as to cause structural damage；In addition, if internal wetly entrance, water
Vapour molecule can be difficult discharge, and internal electronic component is corroded, so that the service life of sensor declines.
The content of the invention：
Technical problem to be solved in the utility model is：The sensor of a kind of achievable high temperature resistant and pressure release effect is provided
Waterproofing protection 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
Air-vent, the second air-vent is offered on 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 seal
It is fixedly mounted, the first air-vent of the protective cover communicates 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 grades of 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 utility model is：Because the normal working environment of sensor is 260 DEG C
And containment vessel inside and outside differential pressure is bigger, it by this structural defence sensor, can both be acted on high temperature resistant, pressure release can also be reached
Effect, may also reach up 7 grades of waterproof purposes.
Brief description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is top view of the present utility model.
Fig. 2 is the sectional view of the utility model front view.
Embodiment：
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
A kind of sensor protection mechanism of waterproof and breathable as depicted in figs. 1 and 2, including protective cover 1, sensor 8, base material
6 and waterproof ventilated membrane 4, the sensor 8 be placed in inside protective cover 1, protective cover 1 sensor 8 is played integral protection effect, and
And be connected and sealed between the sensor 8 and protective cover 1 by the first high temperature resistant waterproof glue 9, opened up on the protective cover 1
There is the first air-vent 2, the second air-vent 7 is offered on the base material 6, the top surface of the waterproof ventilated membrane 4 passes through the second resistance to height
The warm sealing of marine glue 3 is fixedly mounted on the inwall of protective cover 1, and the high temperature resistant of underrun the 3rd of the waterproof ventilated membrane 4 is prevented
Glue 5 is fixedly mounted with the sealing of base material 6, and base material 6 plays a part of strengthening the use intensity of waterproof ventilated membrane 4, the waterproof and breathable
E-PTFE film of the film 4 by foaming specially treated, there is thousands of a diameter of 0.1 μm~1 μm of micropore above, it is allowed to empty
Gas and hydrone are freed in and out, but the globule and dust can be prevented to enter, and can be reached《Shell protection grade》7 grades it is anti-
Water requirement, the first air-vent 2 of the protective cover 1 communicates with the second air-vent 7 of base material 6, and the waterproof ventilated membrane 4
The first air-vent 2 of capping and the second air-vent 7 completely；When the inner space of protective cover 1 causes air pressure to become big because temperature raises
When, its internal gas overflows through the second air-vent 7, the air-vent 2 of waterproof ventilated membrane 4 and first, to realize the inside gas of protective cover 1
Flatten weighing apparatus；When the inner space of protective cover 1 causes air pressure to become big due to temperature rise, gas permeation waterproof ventilated membrane in air
4th, the first air-vent 2 and the second air-vent 7 are added to inside protective cover 1, to realize that the air pressure inside of protective cover 1 balances.
Material is preferably prepared as the one kind of waterproof ventilated membrane 4, the waterproof ventilated membrane 4 is thin for the E-PTFE after foaming
Membrane material, E-PTFE thin-film materials have the advantages of use intensity height and strong resistance to elevated temperatures, and the waterproof ventilated membrane 4 reaches
