Connected to the bottom of slider 1 9, a long groove is provided on the rear side of the body 1. Slider 2 2105 is slidably connected in the long groove. The bottom of the long rod 2104 is rotatably connected to the right side of slider 2 2105. Baffle 2102 is fixedly connected to slider 2 2105 through long plate 2106. When baffle 2102 moves downward, baffle 2102 will block the ventilation opening. When baffle 2102 blocks the ventilation opening, it can effectively prevent rainwater from being blown into the back of the body 1 by the wind, thus preventing leakage.

[0024] The protective device also includes a short rod 2107, a base plate 2108, a pad 2109, a threaded post 2110, and an arc-shaped plate 2111. The short rod 2107 is fixedly connected to the bottom of the baffle 2102, the base plate 2108 is fixedly connected to the bottom of the body 1, the pad 2109 is fixedly connected to the top of the base plate 2108, the threaded post 2110 is threaded through the pad 2109 and the base plate 2108, and the arc-shaped plate 2111 is fixedly connected to the top of the threaded post 2110. When the threaded post 2110 rotates, it strengthens the stability of the base plate 2108 and the ground, effectively preventing the body 1 from being blown over by strong winds and thus causing damage.

[0025] Ventilation openings are provided on the left and right sides of the body 1. The baffle 2102 contacts the ventilation openings, and the short rod 2107 contacts the arc plate 2111. When the baffle 2102 moves downward, it will cover the ventilation openings.

[0026] The cleaning device includes a filter plate 2201, a lead screw 2202, a first support block 2203, a horizontal plate 2204, a second support block 2205, a first scraper 2206, a second scraper 2207, and a third slider 2208. The filter plate 2201 is fixedly connected to the bottom surface inside the machine body 1. The lead screw 2202 is rotatably connected to the bottom surface inside the machine body 1. The first support block 2203 is threadedly connected to the circumferential surface of the lead screw 2202. The horizontal plate 2204 is fixedly connected to the bottom wall inside the machine body 1. The second support block 2205 is threadedly connected to the circumferential surface of the lead screw 2202. The first scraper 2206 is fixedly connected to the support block 2208. On the right side of support block 2205, the top of scraper 2207 is rotatably connected to the bottom front side of scraper 1 2206. Slider 3 2208 is slidably connected to the bottom wall inside the body 1. The bottom of scraper 2207 is rotatably connected to the top of slider 3 2208. When scraper 1 2206 scrapes on the left side of filter plate 2201, scraper 1 2206 will scrape off the impurities and dust on the left side of filter plate 2201. This can effectively prevent impurities from accumulating on the left side of filter plate 2201 and causing the filter plate 2201 to be blocked, thus preventing better ventilation and heat dissipation.

[0027] The scraper 2206 contacts the filter plate 2201. A drain port is provided on the rear side of the machine body 1. The slider 2208 pushes impurities and dust out of the machine body 1 through the drain port, which can effectively prevent dust accumulation and blockage.

[0028] In this embodiment, during operation: when slider 9 moves towards the middle of the machine body 1, slider 9 will drive the long rod 2104 to rotate. When the long rod 2104 rotates, it will drive slider 2105 to slide downwards along the track of the long groove. When slider 2105 slides downwards along the track of the long groove, it will drive the long plate 2106 to move downwards. When the long plate 2106 moves downwards, it will drive the baffle 2102 to move downwards. When the baffle 2102 moves downwards, it will block the ventilation opening. When the baffle 2102 blocks the ventilation opening, it can effectively prevent rainwater from being blown into the machine by the wind. The back of body 1 may cause leakage. When the baffle 2102 moves downward, it will drive the short rod 2107 to move downward. When the short rod 2107 moves downward, it will contact the arc plate 2111. When the short rod 2107 continues to move downward, it will push the arc plate 2111 downward. When the short rod 2107 pushes the arc plate 2111 downward, the arc surface of the arc plate 2111 will push the threaded column 2110 to rotate. When the threaded column 2110 rotates, it will strengthen the stability of the base plate 2108 and the ground, which can effectively prevent the body 1 from being blown over by strong winds and thus causing damage.

[0029] When baffle 2102 moves downward, it drives support block 2203 to move downward. This movement causes lead screw 2202 to rotate, which in turn drives support block 2205 to move downward. This movement then drives scraper 2206 to move downward. As scraper 2206 moves downward, it scrapes the left side of filter plate 2201. While scraper 2206 is scraping the left side of filter plate 2201, its movement causes the scraper to... Scraper 206 scrapes off impurities and dust from the left side of filter plate 2201. As scraper 2206 continues to move downward, it drives scraper 2207 to rotate. As scraper 2207 rotates, it drives slider 3 to move backward. As slider 3 moves backward, it pushes the impurities and dust scraped off from the left side of filter plate 2201 by scraper 2206. When slider 3 pushes the scraped impurities and dust, it pushes them out of the machine body 1 through the drain port, effectively preventing dust accumulation and blockage.
