TECHNICAL FIELDThe present invention relates to the technical field of charging stations, and more particularly to an air duct structure having an IP (ingress protection) protection function.PRIOR ARTAt present, the market for new power vehicles is expanding, and the demand for charging stations is also increasing. AC charging stations are gradually unable to meet the needs of car owners in charging, DC charging stations being the trend for future development of the charging station industry. Given the use of DC charging stations, considerations are taken outdoors, the charging stations being more stringent in terms of IP protection requirements.The protection class of the air duct having the existing louver structure is not sufficient, and requires more material, high cost, and trouble in processing.CONTENT OF THE PRESENT INVENTIONThe present invention solves the problem that the protection class of the air duct having the louver structure is not sufficient in the prior art, which requires a lot of material, a high cost and a trouble in processing. The present invention provides an air duct structure with IP protection function which improves the IP protection class of the charging post by insect protection grids and filter batts. Compared to fin structures and other structures, the air duct structure requires less material, is lower in cost, and is less difficult to process.To solve the above technical problems, the present invention provides the following technical solution: An air duct structure with IP protection function, comprising a door panel, the door panel being provided with a ventilation opening, wherein an air inlet duct is detachably mounted on an inner side of the ventilation opening and an air outlet duct is mounted on an outer side of the ventilation opening, wherein the air inlet duct comprises a detachably connected honeycomb mounting plate, wherein the air outlet duct comprises a detachably connected air guiding hood and a protection arrangement, wherein the protection arrangement is an insect protection grid, wherein the insect protection grid is pressed by a pressing plate.As an advantageous solution, the pressure plate has a rectangular frame structure.As an advantageous solution, the mounting plate comprises a honeycomb panel, side panels and a top panel, wherein the side panels have an F-shaped structure and are located on both sides of the honeycomb panel, and wherein the top panel is located on an upper side of the honeycomb panel.As an advantageous solution, the side plates are connected to the door plate by means of screws.As an advantageous solution, the insect screen is provided on the air guide hood and is pressed by a pressure plate, holders are fixed on both sides of the air guide hood by means of screws, and a pressure plate is rotatably mounted on the holder, the pressure plate being used for pressing the pressure plate.As an advantageous solution, the air guiding hood is connected to the door panel by welding or by means of screws.As an advantageous solution, the protection arrangement is further comprised of a filter batt, wherein the filter batt is mounted on the inside of the insect protection grid.Compared with the prior art, the present invention has the following advantages:(1) The IP protection class of the charging pillar is improved by the insect protection grid and the filter batt;(2) Compared to fin structures and other structures, the air duct structure requires less material, is lower in cost, and is less difficult to process.(3) The grille of the air duct structure may be configured such that the opening area corresponds to the heat dissipation and ventilation area;(4) The guard assembly is removable so that the filter batt at the air inlet and outlet can be replaced independently at a later time;(5) The honeycomb mounting plate is detachably fixed by screws, which facilitates independent replacement of rust at a later time;(6) The risk of leaks in the cabinet body is reduced by the IP protection;(7) The air inlet is vertical and the air outlet is inclined, which reduces air resistance and facilitates heat dissipation of the charging post.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a systematic view of the overall structure of the present invention; FIG. 2 is a schematic view of the overall structure of the present invention; FIG. 3 is an exploded view of the present invention; FIG. 4 is a schematic illustration of the structure of assembly of the insect screen and the printing plate of the present invention.List of reference numbers:1.
