The connection method of the PLC and the required devices are existing public power connection technologies and will not be repeated in this article.

[0040] The beneficial effects of the above embodiments are:

[0041] The RV with a fresh air structure can draw external air into the RV body 1 as the air extraction pump 18 is operated during use, and the incoming air is filtered and purified during the process to ensure the cleanliness and freshness of the air entering the RV body 1. At the same time, the exhaust air pump 11 can be operated to draw the air in the RV body 1 to the outside to realize air circulation, and the incoming air and the exhausted air can exchange heat in the heat exchange device 14 to prevent the temperature loss in the RV body 1, thereby facilitating the maintenance of a good fresh air circulation ventilation efficiency.

[0042] In addition, the operation of the first electric slide rail 2, the linear motor 3 and the second electric slide rail 5 can be used to flexibly adjust the position of the air intake and intake in the RV body 1, so that a certain area of ​​the RV body 1 can be ventilated separately according to needs, preventing odor or gas from diffusing into the entire RV body 1 and affecting the user experience, effectively eliminating problems such as insufficient or excessive fresh air, and improving the practicality of the device.

[0043] The working principle of the above embodiment is:

[0044] When the RV with the fresh air structure is in use, as the air pump 18 is running, the outside air can enter the heat exchange device 14 through the air inlet pipe 1402, and enter the second purifier 15 after passing through the heat exchange device 14, effectively reducing harmful substances in the outside air. The air flowing out of the second purifier 15 can pass through the coarse filter 16 and the fine filter 17 in sequence and enter the second winding drum 19, so as to filter dust particles and PM2.5 and other substances in the air, further improving the air freshness. The air guide hose 21 can guide the air in the second winding drum 19 to the air outlet seat 6, and radiate fresh air to the surroundings through the air outlet seat 6.

[0045] In this process, the air in the RV body 1 can be drawn to the first reel 10 by the air suction hose 9 as the exhaust air pump 11 operates. The first reel 10 can be discharged from the exhaust pipe 1401 after passing through the first purifier 13 and the heat exchange device 14, thereby realizing the fresh air circulation ventilation operation, effectively ensuring the freshness and cleanliness of the air in the RV body 1. In addition, the air of two different flow directions can be heat exchanged in the heat exchange device 14, which can prevent the circulation ventilation from affecting the temperature inside the vehicle.

[0046] In addition, the air outlet seat 6 can move left and right with the operation of the second electric slide rail 5, so as to adjust the fresh air entry position, and the air intake seat 8 can move on the inner top wall of the RV body 1 with the operation of the first electric slide rail 2 and the linear motor 3, so as to adjust the air extraction position, thereby facilitating the ventilation of a certain area of ​​the RV body 1 according to needs, preventing odor or gas from diffusing into the entire RV body 1 to affect the user experience, and effectively eliminating problems such as insufficient or excessive fresh air.
