Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to image 3 , shows a schematic perspective view of a preferred embodiment of the waterproof and breathable membrane of the present invention. The waterproof and breathable film of the present invention is installed at the vent hole provided on the motor, and prevents water vapor and dust particles from entering the vent hole through the waterproof film. , combined with Figure 5 As shown, the height h2 of the waterproof membrane is higher than the height H1 of the drainage groove installed on the motor, which protects the waterproof membrane and ensures that the accumulated water in the cavity is discharged from the drainage groove to prevent the waterproof membrane from becoming invalid due to the immersion of accumulated water. The height h2 of the waterproof membrane is lower than the height H2 of the casing of the motor, whi...

Abstract

The invention relates to a waterproof breathable film installed on a breathable hole of a device. The waterproof breathable film comprises a base body and a waterproof film body, the base body is provided with a first installation portion matched with the breathable hole, the first installation portion is arranged on the outer wall of the breathable hole in a sleeved mode, the top of the first installation portion is fixedly connected with the waterproof film body closing the breathable hole, and the waterproof film body is higher than a drainage channel in the device but lower than an outer shell of the device. The waterproof film body is arranged between the drainage channel and the outer shell, so that the service life of the waterproof film body is prolonged; water on the outer shell of the device is drained through the drainage channel, the water is prevented from covering the waterproof film body and causing efficacy losing of the waterproof film body, the waterproof film body is lower than the outer shell, the function of protecting the waterproof film body is achieved, and the waterproof film body is prevented from being damaged by being touched.

Description

technical field [0001] The invention relates to product accessories, in particular to a waterproof and breathable membrane. Background technique [0002] The motor is equipped with a ventilating member, which is used to alleviate the pressure change in the housing caused by temperature changes, to ensure the ventilation inside and outside the housing, and to prevent foreign matter such as dust and water from intruding into the housing. Generally, automotive lamps, wiper motors, window motors and other automotive electrical components, office automation equipment, home appliances, and medical equipment are all equipped with ventilating components to solve the problem of internal and external problems when the product changes due to internal operation or ambient temperature. If there is a problem of air pressure difference, ensure the air exchange inside and outside the product cavity to balance the air pressure. Generally, the breathable member also needs to have a waterproo...
