[0002] When a room is used for a long time, it is easy to produce odor and pollution. It is slow to remove the odor through normal ventilation, especially in some occasions with larger rooms. The odor is difficult to remove. In order to quickly exhaust the air indoors, a fan called exhaust fan was born.

[0003] Common exhaust fans are usually equipped with dust screens. When used for a long time, a lot of dust will accumulate on the dust screens, and they need to be disassembled and cleaned. However, most existing equipment is fixed with bolts, and tools are needed for disassembly, which is cumbersome. Utility Model Content

A plurality of first springs are fixedly installed on the inner wall of the first groove, and a slide is fixedly installed on one end of the first spring. The slide is in a U-shape, and the slide is slidably connected to the inner wall of the first groove. When the slide is not subjected to external force, the elastic force of the first spring moves the slide out of the first groove, and the slide is movably connected to one side of the shell. The length of the inner wall of the positioning frame is the same as the length of the shell.

[0007] In the preferred technical solution of the utility model, multiple first rotating shafts are rotatably installed between the two sides of the inner wall of the limit frame, and a windshield is fixedly installed on the first rotating shaft. The multiple windshields are movable from top to bottom to fit with the windshield adjacent to the bottom, and the windshield is made of light and thin material.

[0014] The beneficial effects of the utility model are as follows: the utility model provides a fan which is easy to clean through the above design. During installation, the positioning frame is installed in the reserved wind tunnel and then fixed to the wall through the positioning plate and the positioning hole. When in use, the exhaust fan runs to draw air from the room to the outdoors, and the wind shield is rotated and opened by the wind from the shell. When cleaning is needed, the turntable is rotated to drive the third rotating shaft to rotate, and the third rotating shaft drives the second rotating shaft to rotate through the first bevel gear and the second bevel gear. The rotation of the second rotating shaft drives the threaded rod to rotate so that the two sliders move relative to each other. After the movement of the slider drives the positioning rod to move to the disengagement slot, the elastic force of the first spring cooperates with the slide plate to push a part of the shell out of the positioning frame. At this time, the shell can be taken out. When the shell is out of the positioning frame, the elastic force of the second spring and the support plate cooperate to drive the support frame to move up to the top end and extend out of the shell, and then the support frame can be taken out for cleaning. This device can be quickly disassembled without any tools, which is convenient for later cleaning and maintenance, thereby improving the practicality of the equipment.

[0025] See also Figure 3The exhaust mechanism includes an exhaust fan 140, which is fixedly installed at the center of the inner wall of the shell 120. Support frames 141 are symmetrically arranged on both sides of the exhaust fan 140. A filter screen 142 is installed on the inner wall of the support frame 141, and the support frame 141 is slidably installed in the shell 120.

[0026] In some specific implementation schemes, a second groove is symmetrically arranged at the bottom end of the inner wall of the shell 120, and a plurality of second springs 143 are fixedly installed at the bottom end of the inner wall of the second groove.

A through hole matching the support frame 141 is arranged at the top end of the shell 120, and the top end of the support frame 141 is inclined. The second spring 143 and the support plate 144 cooperate to facilitate the taking of the support frame 141, and guide rods 145 are symmetrically fixedly installed on both sides of the top end of the support plate 144. A guide groove matching the guide rod 145 is arranged at the bottom end of the support frame 141, and the guide rod 145 is slidably connected to the inner wall of the guide groove, which is convenient for limiting the support frame 141 during installation.

[0027] See also Figure 4 The adjustment component includes a side plate 152 and a threaded rod 153. The side plate 152 is symmetrically fixedly installed on the inner wall of the cavity. The threaded rod 153 is rotatably installed between the farthest side of the two side plates 152 and one side of the inner wall of the cavity. The slider 150 is threadedly installed on the threaded rod 153. A second rotating shaft 154 is fixedly installed between the two threaded rods 153. A transmission component is installed on the second rotating shaft 154. The two threaded rods 153 are symmetrically arranged, and the slider 150 is slidably connected to the inner wall of the cavity.

[0028] In some specific embodiments, the transmission assembly includes a third rotating shaft 155 and a turntable 156. The third rotating shaft 155 is symmetrically rotatably installed on one side of the shell 120, and the turntable 156 is fixedly installed on one end of the third rotating shaft 155. The other end of the third rotating shaft 155 passes through one side of the shell 120 and is fixedly installed with a first bevel gear. The second bevel gear is fixedly installed on the second rotating shaft 154. The first bevel gear and the second bevel gear are meshingly connected, and can be adjusted without using tools for quick disassembly and installation.

[0029] Working principle: during installation, the positioning frame 110 is installed in the reserved wind tunnel and then fixed to the wall through the positioning plate and the positioning hole. When in use, the exhaust fan 140 is turned to draw air from the room to the outside, and the wind shield 134 is rotated and opened by the wind from the shell 120. When cleaning is needed, the turntable 156 is rotated to drive the third rotating shaft 155 to rotate, and the third rotating shaft 155 drives the second rotating shaft 154 to rotate through the first bevel gear and the second bevel gear. The rotation of the second rotating shaft 154 drives the threaded rod 153 to rotate to make the two sliders 150 move relative to each other. After the movement of the slider 150 drives the positioning rod 151 to move out of the slot, the elastic force of the first spring 131 cooperates with the slide plate 132 to push a part of the shell 120 out of the positioning frame 110. At this time, the shell 120 can be taken out. When the shell 120 is out of the positioning frame 110, the elastic force of the second spring 143 and the support plate 144 cooperate to drive the support frame 141 to move up to the top and extend out of the shell 120, and then the support frame 141 can be taken out for cleaning.
