Problems solved by technology
Since the charging pile is installed in the open air all year round, it is vulnerable to water vapor in the air. Water vapor can easily enter the interior of the charging pile from the vent of the charging pile, and then cause damage to the internal circuit of the charging pile, thus affecting the normal use of the charging pile. Therefore, waterproof devices such as desiccant are generally installed at the vent of the charging pile to remove water vapor in the air. However, after a long time of use of the desiccant, due to the large amount of moisture absorbed, it is easy to lose the drying function, so that it cannot work normally. Waterproof brings a lot of trouble to charging pile users, so we propose a waterproof device for the air inlet of electric vehicle charger

The invention discloses a waterproof device for an air inlet of an electric vehicle charger. The vertical sections of the air inlet pipe and the second air inlet pipe are both rectangular, and the first air inlet pipe and the second air inlet pipe are provided with vertical filters and valves, and the second air inlet pipe extends to the inside of the shell. A vertically arranged water-absorbing layer is fixed in the middle of the second air inlet pipe, and a vertically arranged fixing plate is fixed on one side of the second air inlet pipe. Waterproof, preventing external moisture from entering the interior of the charging pile. It can also detect the water vapor content of the gas entering the charging pile, so as to detect whether the desiccant is invalid. At the same time, heat the desiccant that has failed to restore the desiccant function. , so that the service life of the charging pile is long.
Description
technical field [0001] The invention relates to the technical field of electric vehicle chargers, in particular to a waterproof device for an air inlet of an electric vehicle charger. Background technique [0002] During the use of electric vehicles, chargers such as charging piles are usually required to charge the electric vehicles. Since the charging pile is installed in the open air all year round, it is vulnerable to water vapor in the air. Water vapor can easily enter the interior of the charging pile from the vent of the charging pile, and then cause damage to the internal circuit of the charging pile, thus affecting the normal use of the charging pile. Therefore, waterproof devices such as desiccant are generally installed at the vent of the charging pile to remove water vapor in the air. However, after a long time of use of the desiccant, due to the large amount of moisture absorbed, it is easy to lose the drying function, so that it cannot work normally. Waterproo...
