These small creatures not only cause itching and discomfort, but also may spread diseases and pose a threat to health. This problem is particularly prominent in cabin-type buildings (such as campers, mobile homes, temporary shelters, etc.), because these spaces usually need to open doors and windows frequently to maintain ventilation, but must also be strictly prevented from mosquitoes invading, which requires the use of mosquito nets.

[0003] Publication No. CN108374629A discloses a vertical pole with a winding gauze and a hidden integrated protective gauze, which relates to the field of doors and windows; the vertical pole with a winding gauze disclosed by the present invention has a fixed shaft and a reel sleeved outside the fixed shaft and rotatable relative to the fixed shaft arranged in its shell, and the reel is connected to the fixed shaft by a torsion spring; the fixed end of the gauze is fixed and wound on the reel, and the free end of the gauze passes through a through hole and is located outside the shell; a buckle is arranged at the free end of the gauze, and a slot matched with the buckle is also arranged on the shell; the vertical pole can be assembled into a protective net, and the assembled protective net can be installed on the window frame to form a protective window, and the window sash light can be operated to drive the unfolding or folding of the protective net. Through the cooperation of the buckle and the slot, when the protective net is folded, the torsion spring drives the reel to rotate to wrap the gauze, and the gauze is then stored in the shell and hidden, which is simple and convenient to operate and improves the aesthetics. When the protective net is unfolded, the gauze unfolds with the movement of the vertical pole, playing a role of protecting against theft and mosquitoes.

[0040] The above scheme is adopted: by setting the cooperation of structures such as the piston 207 and the baffle 403, it is convenient to clean the mesh cover 103 when it is folded up. When the lifting window 302 is closed, the second gear 108 will rotate in the opposite direction, so that the two pistons 207 move towards each other, increase the air pressure inside the air storage tank 205, and the baffle 403 inside the first groove 401 is rotated in the direction away from the air storage tank 205 by the air pressure, so that the channel of the first groove 401 is opened, and the gas inside the air storage tank 205 is discharged from the first groove 401, and the mesh cover 103 that is about to be stored in the storage groove 204 at the bottom of the sliding plate 110 is blown, and mosquitoes and dust attached to the mesh cover 103 are blown away by the airflow, and the mesh cover 103 is self-cleaned to prevent mosquitoes and dust from entering the device and causing damage and pollution to the device, thereby extending the service life of the mesh cover 103, reducing the replacement frequency and cost, and at the same time alleviating the burden of regular manual cleaning, reducing the maintenance frequency and complexity, and saving time and energy.

[0041] The working principle and use process of the present invention are as follows: first, the mounting seat 201 is installed on the cabin shell 301 by bolts, so that the first gear 101 located behind the mounting seat 201 is meshed with the second rack 305. At this time, the handle 303 is pulled upward to make the lifting window 302 move upward inside the third slide groove 306. The lifting window 302 moves upward to drive the second rack 305 to move upward, thereby rotating the first gear 101. The rotation of the first gear 101 will drive the connecting tube 102 and the first bevel gear 106 fixedly connected thereto to rotate. The rotation of the connecting tube 102 will tighten the volute spring 105, so that the spiral circle spacing of the volute spring 105 is reduced, thereby storing energy. At the same time, the rotation of the connecting tube 102 will stretch the mesh cover 103 and the support bar 1 04, and the rotation of the first bevel gear 106 will drive the second bevel gear 107 meshing therewith to rotate, and the rotation of the second bevel gear 107 will drive the second gear 108 and the screw rod 109 to rotate, wherein the two screw rods 109 symmetrically centered around the connecting tube 102 will rotate in opposite directions, thereby driving the sliding plate 110 to move upward synchronously with the lifting window 302 inside the first sliding groove 202, so that the sliding plate 110 pulls the stretched mesh cover 103 and the support bar 104 out of the storage groove 204 and tightens them, at this time, the support bar 104 will fit with the surface of the cabin shell 301, so that the tight mesh cover 103 blocks the gap between the lifting window 302 and the window edge, preventing mosquitoes from entering the cabin during the window opening process;

[0042] At the same time, the rotation of the two second gears 108 will drive the two first racks 206 meshing therewith to move away from each other, thereby driving the two pistons 207 to move away from each other inside the air storage tank 205. Increasing the distance between the two pistons 207 will reduce the air pressure between them, and the air pressure will cause the baffle 403 in the second groove 402 to rotate in the direction close to the air storage tank 205 and squeeze the coil spring 405, so that external air can enter the air storage tank 205 through the second groove 402. After the lifting window 302 stops moving, the baffle 403 will reset under the elastic force of the coil spring 405, so that the air storage tank 20 5, and when the lifting window 302 is closed, the second gear 108 rotates in the opposite direction, so that the two pistons 207 move toward each other, increasing the air pressure inside the air storage tank 205, and the baffle 403 inside the first groove 401 rotates away from the air storage tank 205 through the air pressure, opening the channel of the first groove 401, so that the gas inside the air storage tank 205 is discharged from the first groove 401, and the mesh cover 103 at the bottom of the sliding plate 110 that is about to be stored in the storage groove 204 is blown, and mosquitoes and dust attached to the mesh cover 103 are blown away by the airflow, so that the mesh cover 103 is self-cleaned.
