[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 The illustrated embodiment of a vehicle charging terminal with a breathable valve comprises a charging gun body 1, wherein a first shell 2 and a second shell 3 are clamped on the outside of the charging gun body 1, a fixing screw 4 is arranged on the outside of the first shell 2, and the first shell 2 and the second shell 3 are fixedly connected by the fixing screw 4. The first shell 2 and the second shell 3 can be stably installed on the outside of the charging gun body 1 by the fixing screw 4, so as to seal and protect the electronic components on the charging gun body 1, and an end cover 6 is slidably sleeved on the end of the outer wall of the charging gun body 1. When the charging gun body 1 is not in use, the end cover 6 can seal and protect the interface at the end of the charging gun body 1, so as to reduce the probability of dust entering the interface at the end of the charging gun body 1, and an elastic snap fastener is arranged inside the end cover 6, so as to improve the stability of the end cover 6 sleeved on the end of the charging gun body 1, and an elastic band 7 is fixedly connected to the outer wall of the end cover 6, and a hanging ring is fixedly connected to the end of the elastic band 7. The elastic band 7 can be connected to the outside of the first shell 2 or the second shell 3 by using the hanging ring, so as to prevent the end cover 6 from falling off and being lost after the end cover 6 is pulled off under the action of the elastic band 7.

[0022] In particular, a heat dissipation component 5 is provided at the bottom of the first shell 2 and the second shell 3, and the heat dissipation component 5 includes a breathable valve body 51, a mounting shell 52 and an exhaust fan 53. The working principle of the breathable valve body 51 is based on the pressure difference of the fluid passing through the valve. When the pressure difference on both sides of the valve is greater than or equal to the opening pressure required by the valve, the valve will open to allow gas to flow. When the pressure drops below the closing pressure required by the valve, the valve will close. The breathable valve body 51 is clamped at the bottom between the first shell 2 and the second shell 3, and the exhaust fan 53 is installed at the bottom of the first shell 2 and the second shell 3 through the mounting shell 52. The exhaust fan 53 is located at the bottom of the breathable valve body 51, so that when the charging gun main body 1 is working, the exhaust fan 53 is powered on to blow out the airflow inside the mounting shell 52, thereby reducing the air pressure inside the mounting shell 52, and the first shell 2 and the second shell 3 are closed. The air pressure inside the shell 3 is greater than the air pressure inside the mounting shell 52. The gas inside the first shell 2 and the second shell 3 flows to the inside of the mounting shell 52 through the breathable valve body 51, so that the heat generated by the charging gun main body 1 due to the charging work flows to the outside through the breathable valve body 51. The bottoms of the opposite sides of the first shell 2 and the second shell 3 are provided with card grooves. The outer wall of the breathable valve body 51 is slidably engaged with the card groove. The outer wall of the breathable valve body 51 is sleeved with a sealing leather cover. The sealing leather cover can improve the sealing between the outer wall of the breathable valve body 51 and the first shell 2 and the second shell 3. Therefore, when the exhaust fan 53 stops working, the air pressure inside the first shell 2 and the second shell 3 is the same as the air pressure inside the mounting shell 52. At this time, the breathable valve body 51 is in a sealed state, thereby preventing external dust from entering the first shell 2 and the second shell 3 through the breathable valve body 51.

[0023] Furthermore, a sealing gasket that fits the first shell 2 and the second shell 3 is fixedly connected to the top of the installation shell 52, and the sealing gasket can improve the sealing between the installation shell 52 and the first shell 2 and the second shell 3. An exhaust hole corresponding to the exhaust fan 53 is opened at the bottom of the installation shell 52, and a dustproof net 54 is installed inside the exhaust hole, so that when the exhaust fan 53 is working, the gas inside the installation shell 52 can be blown to the outside through the dustproof net 54, and the exhaust fan 53 is electrically connected to the power module on the charging gun body 1 through the power cord, so that when the charging gun body 1 is powered on to charge the car, the exhaust fan 53 is powered on and works, and the bottom of the first shell 2 and the bottom of the second shell 3 are fixedly connected with a fixing plate 55, a fixing plate 55 is fixedly connected with a clamping block 56 on one side of the mounting shell 52, a positioning hole is provided on the outer wall of the mounting shell 52, and the outer wall of the clamping block 56 is slidably engaged with the inner cavity of the positioning hole, a fixing collar 57 is installed on the outside of the exhaust fan 53, and a connecting plate 58 is fixedly connected with the outer wall of the fixing collar 57, a docking groove is provided on one side of the clamping block 56, and one end of the outer wall of the connecting plate 58 is slidably engaged with the inner cavity of the docking groove, the fixing plate 55 can be clamped and fixed to the mounting shell 52 and the connecting plate 58 through the clamping block 56, and the fixing screws 4 are removed to relatively separate the first shell 2 and the second shell 3, so that not only the breathable valve body 51 but also the mounting shell 52 and the exhaust fan 53 can be disassembled.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
