[0002] Electric vehicles need charging piles to charge. More and more owners will install charging piles in underground garages. The convenience of underground charging piles provides great convenience for people's daily travel.

[0003] Existing charging piles are generally composed of a shell, a controller and a charging gun. The shell is generally provided with heat dissipation holes to facilitate the heat dissipation of internal electrical components. The existing heat dissipation holes are generally exposed. Since the basement environment is usually dark and humid, the external moist air can easily enter the interior of the charging pile during ventilation and heat dissipation. The internal electrical components are easily affected by moisture or condensation, which can easily cause damage and affect safety during use. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a moisture-proof and dehumidifying basement charging pile, which can absorb moisture from the incoming air and prevent the entry of moisture. The bagged desiccant on both sides can alternately absorb and dehumidify moisture, which greatly improves the safety of the basement charging pile when in use. The bagged desiccant has a long service life and is easy to replace, which reduces the labor burden of maintenance personnel and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a moisture-proof and dehumidifying underground charging pile, comprising a housing and a dehumidification unit;

[0006] A charging gun is provided at the lower end of the shell, fans are provided at the upper ends of the left and right inner side walls of the shell, and guide shells are provided at the upper ends of the left and right side walls of the shell. The guide shells and fans correspond to the positions of the heat dissipation holes on the left and right side walls of the shell;

[0007] The dehumidification units are respectively movably plugged into the lower end of the guide shell;

[0008] It also includes a controller and a touch screen. The controller is arranged above the rear side wall of the shell, and the touch screen is arranged inside the rectangular hole on the front side of the shell. The controller and the touch screen are bidirectionally electrically connected. The input end of the charging gun is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to an external power supply.

[0009] Furthermore, the dehumidification unit includes a mesh shell and a bagged desiccant. The mesh shells are movably plugged into the interior of the guide shell. The bagged desiccant is placed inside the mesh shell to dry the incoming air.

[0010] Furthermore, the dehumidification unit also includes a lower cover, which is movably plugged into the lower end of the mesh shell, and the bagged desiccant is located above the lower cover, which is convenient for positioning the bagged desiccant.

[0011] Furthermore, the dehumidification unit also includes filter screens, which are respectively arranged on the lower surface of the lower cover to facilitate air filtering.

[0012] Furthermore, the dehumidification unit also includes rectangular bars, which are respectively arranged on the front side of the lower surface of the lower cover to facilitate the buckling of the lower cover.

[0013] Furthermore, an inner guide shell is provided on the right side wall of the outer shell, and the inner guide shell is arranged in cooperation with the fan on the right side to facilitate diagonal flow of air inside the outer shell.

[0014] Furthermore, a spring sheet is provided through a rectangular block below the guide shell away from the side of the outer shell, and a positioning block is provided in the middle of the lower surface of the spring sheet. The end of the positioning block close to the outer shell extends to the interior of the guide shell and is cooperated with the laterally adjacent mesh shell. A rubber cap is provided at the front end of the spring sheet to facilitate the positioning of the mesh shell.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. While charging, one of the fans is working, and the fan exhausts air outward. The hot air inside the shell enters the inside of the guide shell through the heat dissipation holes, and then passes through the mesh shell, bagged desiccant, lower cover and filter to be discharged to the outside. The hot air will heat the bagged desiccant when passing through the gap, and then the bagged desiccant can be dried and dehumidified. At the same time, the outside air will pass through the filter, lower cover, bagged desiccant and mesh shell to replenish the inside of the shell, and then the air inside the shell can circulate with the outside air, which is convenient for the heat dissipation of the internal electrical components. The filter screen filters the air to prevent the entry of dust. The bagged desiccant absorbs and dries the incoming air to prevent the entry of wet air. During use, the incoming air can be humidified to prevent the entry of moisture. At the same time, the exhausted hot air can be used to dry and dehumidify the bagged desiccant on the other side. The two fans run alternately, and the bagged desiccant on both sides can alternately absorb and dehumidify, which extends the service life of the bagged desiccant, improves the safety of the basement charging pile when in use, and reduces the labor burden of maintenance personnel.

[0017] 2. When the bagged desiccant needs to be replaced, the rubber cap can be moved, and the spring sheet will undergo elastic deformation to drive the positioning block to separate from the mesh shell. Then the mesh shell will slide out of the guide shell due to gravity, and then the mesh shell will be turned over and the lower cover will be buckled through the rectangular bar. The lower cover is removed from the port of the mesh shell, and then the bagged desiccant inside can be replaced. The bagged desiccant on both sides is external and can be quickly replaced by plugging and positioning, which greatly improves the convenience of charging pile maintenance.
