Abstract
A lamp waterproof ventilating device, comprising a lamp shell, which is characterized by comprising a ventilating nozzle whose one end is communicated with an inner cavity of the lamp shell, the other end is covered with a gas and liquid filtering cover made of micropore material. Due to the adoption of such structure, the pressure of the lamp shell will increase when the external temperature rises, and the pressed air in the lamp shell will be relived through an installation hole, the gas and liquid filtering cove; when the external temperature decreases, the pressure in the lamp shell will reduces and the air will enters into the lamp shell through the gas and liquid filtering cove and the installation hole, to keep the external and internal air of the shell balance, thereby preventing the deformation of the lamp shell and the water leakage of the lamp due to the deformation of the lamp shell. So the utility model can not only prevent the deformation of the lamp shell, and the negative pressure water absorption, but can prevent the seal performance decrease of the lamp shell, so as to prolong the service life.
Description
Technical field
The utility model relates to a kind of light fixture, especially a kind of light fixture waterproof air-breather.
Background technology
Present prior art, the light fixture primary structure of outdoor use is: shell, power supply lead wire, circuit unit, light source, wherein the cavity of shell formation holds light source and circuit unit, airtight assurance light fixture water proof and dust proof, but the cavity structure of outdoor lamp is in environment for use, the experience temperature Change, self also generate heat during light fixture energising work, cooling again after the outage, air pressure raise when temperature raise, the pressure extrusion shell that produces is sought pressure release passage, gas pressure intensity decline when temperature reduces in the cavity produces negative pressure and oppositely pushes housing, so do not stop circulation, the physical deformation of shell can destroy light fixture maintenance opening gradually, if the sealing property in technology slits such as electric wire inlet is cooling at this moment, be attached with moisture on the shell again, will absorb moisture and enter lamp interior.Summer, this process was the most obvious, summer, burning sun was exposed to the sun outdoor lamp to add the airtight generation greenhouse effects of light fixture, lamp temperatures raises, at this moment the sun rain that runs into is the low temperature rainwater that gets off in the high-altitude, pouring is sharply cooling on lamp outer casing, the water that sticks on the lamp outer casing is inhaled into inside, and the light fixture that short circuit damages is also just maximum.
Summary of the invention
The purpose of this utility model is: a kind of light fixture waterproof air-breather is provided, and it can not only prevent the lamp outer casing distortion, prevents the negative pressure suction, and can prevent that the sealing property of lamp outer casing from descending, and increases the service life.
The utility model is achieved in that a kind of light fixture waterproof air-breather comprises lamp outer casing, and its special character is: also comprise a ventilation mouth, ventilation mouth one end communicates with the lamp outer casing inner chamber, and the gas-liquid filteration cover that the other end is made by poromerics covers.
Described light fixture waterproof air-breather, its special character is: also have an installing hole on the lamp outer casing, an end of ventilation mouth is installed on the installing hole, and the other end is installed the gas-liquid filteration cover.
Described light fixture waterproof air-breather, its special character is: an end of ventilation mouth has screw thread, and internal thread is arranged on the installing hole, and the end of thread of ventilation mouth passes sealing gasket, installing hole cooperates with nut.
Described light fixture waterproof air-breather, its special character is: also comprise a sealing ring, the sealing ring profile is " worker " font, and sealing ring is installed in the installing hole, and the end that the ventilation mouth cooperates with installing hole inserts in the centre bore of sealing ring.
Described light fixture waterproof air-breather, its special character is: described ventilation mouth and installing hole abutting end have the axial groove that connects wall thickness, and there is the non-return hook end; The ventilation mouth passes sealing gasket and cooperates with installing hole.
Described light fixture waterproof air-breather, its special character is: ventilation mouth and lamp outer casing are made into integration, and the gas-liquid filteration cover is installed on the ventilation mouth.
Described light fixture waterproof air-breather, its special character is: ventilation mouth and lamp outer casing are integrated into, and gas-liquid filteration cover and lamp outer casing are fixedly connected.
The utility model light fixture waterproof air-breather also comprises a ventilation mouth, and ventilation mouth one end communicates with the lamp outer casing inner chamber, and the gas-liquid filteration cover that the other end is made by poromerics covers.Owing to adopt such structure, raise when meeting ambient temperature, the lamp outer casing internal pressure increases, and the pressure in the lamp outer casing is by installing hole, the pressure release of gas-liquid filteration cover; When ambient temperature reduces, pressure in the lamp outer casing reduces, and air enters lamp outer casing by gas-liquid filteration cover, installing hole, makes the inside and outside atmospheric pressure of lamp outer casing keep balance, prevented the lamp outer casing distortion, and prevented to leak because of the light fixture that the lamp outer casing distortion causes.So it can not only prevent the lamp outer casing distortion, prevent the negative pressure suction, and can prevent that the sealing property of lamp outer casing from descending, and increases the service life.
