Abstract

The utility model discloses a waterproof heat dissipation respirator. The respirator comprises a top cover (1), a top plug (2), a filter screen silica gel ring (3), an O-shaped ring (4) and a joint body (5), wherein, the filter screen silica gel ring (3) and the top plug (2) are arranged in a groove formed at the top end of the joint body (5); and four small holes, in which the top cover (1) can be inserted and fixed, are formed at four plum blossom corners at the upper part of the joint body (5). The utility model has the benefits that heat in closed equipment can be dissipated fast, and air pressure inside the equipment and air pressure outside equipment can be equalized effectively, so that the utility model ensures that the respirator cannot leak in an area five meters under water, mechanical property of the respirator can be maintained in the area five meters under water, and the installation of the filter screen is tight and efficient. The utility model further has the advantages of firm top cover installation, maintenance-free filter screen, simple structure, and convenient and effective installation.

Description

Waterproof cooling respirator

Technical field

The utility model relates to a kind of ventilative device of waterproof cooling that is used for aspect equipment such as electrical equipment, light fixture, motor, new forms of energy and communication, especially a kind of heat radiation, waterproof and dustproof and ventilative respirator that is applicable to closed heat-producing device.

Background technology

At present, known heat-producing device heat radiation generally all is out modes such as ventilation mouth, installation fan, heat dissipation problem is to have solved although it is so, but after running a period of time, device interior will amass completely a lot of dusts, reduced the equipment operation performance and influenced service life of equipment etc., and this mode is not suitable for outdoor equipment; If use in wet environment, aqueous vapor will enter into device interior and cause line short or fault; If equipment need touch water or need 3M-5M depth of water environmental work, be difficult at present realize; For the product facility that the IP class requirement is arranged, in order to reach quick heat radiating and high-grade IP barrier propterty requirement, generally adopt aluminium alloy or specific alloy material enclosed construction to realize, but realize that cost is too high and not necessarily effective by shell.Protect dirt for the waterproof of outdoor lamp and each electric appliances, motor, sophisticated product equipment and adopt full-closed structure substantially, according to inspection information and field test: the light fixture of good seal performance or all kinds ofly the heat-producing device shell is arranged after closing, will open housing is difficult at once, and poor sealing performance, can easily open at once, this is the inside and outside differential pressure problem; For example, the rainfall meeting causes the rapid temperature of the outer generation of equipment to descend, the rapid reduction of temperature can cause inner 150mbar of generation of water-tight equipment even bigger vacuum, like this, air and moisture just can be by seal clearance access arrangement inside, moisture attached on the inwalls of equipment and condense into the globule, and this will have a strong impact on the performance of product.Constantly temperature, dust, dirt and the moisture that changes affects outdoor water-tight equipment widely.And for example, the continuous variation of temperature makes sealing strip along with STRESS VARIATION, and that sealing strip is produced is tired-this means to be not only moisture, comprises that water and various liquid finally can see through access arrangement inside, slit, has sealed also with regard to blow-by.Show through consulting related data, outdoor sealed lamps or all kinds ofly have that water leakage ratio reaches 5%～8% in about 2%～3%, two years of heating water-tight equipment water leakage ratio in a year, a lot of is exactly to cause internal circuit board or components and parts to damage because leak.Present known waterproof and breathable product, because of adopt " waterproof ventilated membrane is bonded on the silicone rubber gasket; put into silicon rubber loop and waterproof ventilated membrane in the plug together then; screw on plug screw compress " mode, like this, can not guarantee fully that plug screw screws place's 100% sealing, and the requirement that does not reach the water resistance 3M depth of water; And in time, variations in temperature, solar radiation with contact with various chemical products etc., all can make the plug screw place of screwing produce that slit and silicon rubber loop are aging to be shunk etc., cause the non-watertight and damage equipment internal product (particularly electronic element) of product etc.Adopting the air-vent of the ventilative plug screw that aforesaid way installs in addition is straight wall type, adds that the top, hole has top cover to cover, and is unfavorable for that like this device interior hot gas distributes the quick exchange with inner air and outer air fast; The top cover fixed form that also has at present known waterproof and breathable plug screw is to realize by four on the plug little hooks, such fixed form is easily fallen top cover and is come off, as being installed on the underground lamp of public place or the palp place of hand, the people who easily causes top cover is for peeling off.

Summary of the invention

Shortcoming at existing waterproof cooling respirator, the utility model provides a kind of novel ventilative device of the waterproof cooling that is used for aspect equipment such as electrical equipment, light fixture, motor, new forms of energy and communication, especially a kind of heat radiation, waterproof and dustproof and ventilative respirator that is applicable to closed heat-producing device.

To achieve these goals, the measure taked of the utility model:

Waterproof cooling respirator comprises top cover, top plug, filter screen silica gel circle, O type circle, fittings body; Described filter screen silica gel circle is put into the fittings body top groove, is pressed into the top plug then, and the top of described fittings body is provided with groove, is inserted with top cover in the groove; Described fittings body top shape is quincunx, and on four angles of plum blossom aperture is arranged, and described top cover profile is quincunx, and on four jiaos in the plum blossom protruding spile is arranged; Described fittings body crown center inside groove is the fillet square, and endoporus is by the X stent support, on four jiaos in the peripheral plum blossom four apertures is arranged; The top plug is the fillet square;

Described top plug inner hole wall is the taper surface structure, and base plane has waterproof tongue circle;

O type circle is installed in the middle of the described obturating plug.

The beneficial effects of the utility model: the equipment of sealing can outwards be dispelled the heat and active balance inside and outside air pressure fast, can guarantee the non-leakage and mechanical performance change of generation in 5m zone under water, filter screen is installed closely effectively, and have that top cover is installed firmly, filter screen is non-maintaining, simple in structure and easy for installation effectively.
