Embodiment Construction
[0019] figure 1 It is a schematic diagram of the use state of the waterproof ventilation device of the embodiment of the present invention.
[0020] refer to figure 1 , the embodiment of the present invention provides a waterproof ventilation device, which includes a liquid collection part 3 and a protective cover 2 . Wherein, the liquid collecting part 3 includes a cylindrical liquid collecting chamber 7, and the liquid collecting part 3 is used to collect the liquid entering it. The protective cover 2 is arranged on the upper end of the adjustment execution part 4 and is provided with a surrounding edge. The protective cover 2 can fasten the liquid collecting part 3 inside the protective cover 2, which can effectively prevent the entry of external liquid. An adjustment executing part 4 is arranged between the liquid collecting part 3 and the protective cover 2 , and the adjusting executing part 4 is telescopically arranged in the liquid collecting cavity 7 of the liquid co...

The embodiment of the invention provides a water-resisting and ventilation device. The water-resisting and ventilation device comprises a liquid collection part, a protective cover and an adjustment execution part; the liquid collecting part comprises a cylindrical liquid collecting cavity; the adjustment execution part can be telescopically arranged in the liquid collecting cavity; and the protective cover is arranged at the upper end of the adjustment execution part and is provided with a surrounding edge. The waterproof ventilation device has the following states: an open state: the adjustment execution part extends out from the liquid collecting cavity, and the surrounding edge of the protective cover is separated from the liquid collecting cavity of the liquid collecting part, so that a separation gap for air incoming and / or liquid incoming can be formed; and a closed state: the adjustment execution part contracts into the liquid collecting cavity, and the surrounding edge of the protective cover and the liquid collecting cavity of the liquid collecting part are closed, so that an isolation state for air prevention and / or liquid prevention can be realized. With the device adopted, when it is judged that the flow rate of external liquid reaches a preset value, the adjustment execution part is operated so as to contract, so that the protective cover can be closed, and external air and liquid can be prevented from coming into the device, and water-resisting and ventilation effects can be realized.
Description
technical field [0001] The invention relates to equipment ventilation technology, in particular to a waterproof ventilation device. Background technique [0002] With the progress of society, the degree of electrification of all walks of life is constantly increasing, the user capacity is increasing, and the heat dissipation problem of electrical equipment is becoming more and more prominent. However, the conventional ventilation and heat dissipation methods conflict with the protection requirements of the equipment. [0003] Generally, the following three methods are used for ventilation, heat dissipation and waterproofing: [0004] The first is to ventilate and dissipate heat through louvers. This method can only meet the waterproof within a certain angle range upwards but not waterproof in other directions. [0005] The second is to ventilate and dissipate heat through ventilation windows with water shields. This method can meet the waterproof and ventilation requirement...
