Abstract
The utility model discloses a water-proof and dust-proof device for equipment. An air vent is arranged on an equipment casing. The water-proof and dust-proof device comprises an airtight expansion-shrinkage body arranged on the equipment casing. The airtight expansion-shrinkage body comprises an air cavity and an air cavity vent, and the air cavity vent is in butt joint with the air vent in sealing mode. When outer air pressure is higher than air pressure inside the equipment, the air cavity is expanded along with the inflation of the air from the air vent and extrudes the air inside the equipment so that the air pressure inside the equipment and the outer air pressure are balanced, and moisture, dust and the like are prevented from entering the inside of the equipment from a connector of the equipment. When the outer air pressure is lower than the air pressure inside the equipment, the air cavity is shrank along with flowing out of the air from the air cavity vent, and the air stored in the air cavity is exhausted from the air vent, thereby obtaining balanced air pressure between the inside and the outside of the equipment. The protective device forms a good protective screen between the equipment and the outside environment, the outside moisture and dust are prevented from entering the inside of the equipment, and durability of the device is obtained.

Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
Please refer to Fig. 1-3, is the schematic diagram that is installed in the dust and water proof apparatus 1 on the apparatus casing 4 shown in Fig. 1.Wherein, apparatus casing 4 is provided with air vent hole, and the air vent hole of film promptly is set in the prior art.Dust and water proof apparatus 1 comprises airtight breathing body 2, further, airtight breathing body 2 comprises air cavity 21 and air cavity blow vent (not shown), described air cavity blow vent docks with the air vent hole sealing on being arranged on apparatus casing 4, described air cavity 21 is along with gas charges into and expands from the air cavity blow vent, along with gas flows out and shrinks from the air cavity blow vent.
In one embodiment, described airtight breathing body 2 is arranged on the inside of described equipment.Can not influence the use of equipment like this, and attractive in appearance, expand but need reserve the close breathing body 2 of certain space air feed at device interior.
Described airtight breathing body 2 is rubber-like, can expands and shrink, and has watertightness material composition preferably.
In a kind of preferable embodiment, described airtight breathing 2 is the elasticity balloon body.
Described flange 22 also is provided with sealing ring 23 with the junction of airtight breathing body air cavity blow vent, forms the environment of a sealing further, prevents steam and dust entry communication device interior.
In another kind of embodiment, described device also comprises with described air cavity blow vent and cooperating, and is used for sealing the connector 3 of described air cavity blow vent, but described connector is provided with the come in and go out air-vent 31 of described air cavity of supplied gas.The sizableness of the size of described connector 3 and described flange 22 eyelets is to form better sealing.The main effect of set air-vent 31 is when ambient pressure and device interior air pressure imbalance on the connector 3, realizes the equilibrium of air pressure, and the moisture and the dust that enter balloon body 21 can be cleared up the outside from this pore.Guaranteed that moisture and dust are can't access arrangement inner and influence its operate as normal.And by connector 3 is set, can change the size of set air-vent 31 on it as required, realize air pressure balance better; And airtight breathing body and external environment can be isolated, prolong its useful life.
Wherein, the material of link 3 can be selected as required, for example metal, rubber or other suitable materials.
During installation, adopt splicing or other can guarantee that both are connected by bubble-tight mode fixing compact airtight breathing body 2 and flange 22, and make the open-shaped attitude of air cavity blow vent of airtight breathing body 2, then sealing ring 23 is contained on the flange 22, and will comprise air cavity 21, airtight breathing body 2 that the waterproof sealing flange 22 of sealing ring 23 is housed is installed on the air vent hole of shell 4.At last connector 3 is installed on the waterproof sealing flange 22, to be connected on the device housings 4 with realizing airtight breathing body security seal.Connector 3 can be splicing, crimping or other suitable connected modes with being connected of waterproof sealing flange 22.
Need to prove that dust and water proof apparatus 1 can be installed in any position of equipment, and is not limited only to disclosed set-up mode in the accompanying drawing.
Please refer to Fig. 4, the view when being respectively the idle and work of dust and water proof apparatus 1 shown in the figure.When ambient pressure is higher than device interior air pressure, ambient atmosphere will enter airtight breathing body 2 from air-vent 31 under the effect of draught head, airtight breathing body 2 expands and the extrusion equipment gas inside, make the pressure rises of device interior, thereby, prevent the connector access arrangement inside of the pollutant slave unit such as steam, dust in the atmosphere with the external atmosphere pressure balance.When ambient pressure was lower than device interior air pressure, airtight breathing body 2 was squeezed, by the gas of air-vent 31 discharging storages.Fig. 4 left side is the deflated state of airtight breathing body 2, and the right side is the inflated condition of airtight breathing body 2.The dust and water proof apparatus that the utility model provides provides barrier for the connector of offering on the equipment, when external atmosphere pressure during greater than the device interior atmospheric pressure, gas is at first from the steam vent access arrangement of dust and water proof apparatus, thereby device interior air pressure is increased, prevent that gas from entering from connector, thereby pollute connector and device interior circuit etc.
Need to prove, being provided with of air-vent 31 sizes of connector 3 need be satisfied the requirement that technology is provided with, promptly when the sealing mechanism that is provided with on the connector works, need to guarantee that the air-tightness of air-vent 31 is lower than the air-tightness of connector, thereby guarantee that ambient atmosphere at first enters from steam vent.
In order to allow those skilled in the art can understand content of the present utility model better, below the contact and the difference of air vent hole mentioned in the utility model, air cavity blow vent, air-vent are explained: air vent hole is arranged on the opening on the equipment, and is corresponding with the opening that film is set in the prior art; The air cavity blow vent is air cavity and the extraneous opening that exchanges air-flow, and the air cavity blow vent docks with air vent hole, to realize air cavity and extraneous exchange air-flow; Air-vent is among the another kind of embodiment, is arranged on the opening on the connector, and this moment, air-vent exchanged air-flow with the external world, thereby realizes air cavity and the extraneous air-flow that exchanges.
Protector disclosed in the utility model just can processing and manufacturing with common parts, made things convenient for promoting the use of of this protector, and this protector forms by flange, sealing ring and connector and repeatedly is sealedly and fixedly connected, make this protector have better sealing property, play the effect of better water proof and dust proof; The utility model is suitable on the equipment that various air-tightness have relatively high expectations, and for example communication apparatus and various precision instruments etc. have bigger range of application.
Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
