[0041] Before use, the fixed ring 3 fixed at the top of heat preservation cotton 1 needs to be slid along the groove on the outer surface of air pipe 17 and sleeved on the outer side of air pipe 17, and the sliding layer 8 can reduce the frictional damage of heat preservation cotton 1 to air pipe 17 during installation and disassembly, and can ensure smooth and smooth installation, and during use, the fixed mechanism 2 needs to be installed on the fixed ring 3, the sliding block 6 is pulled down to drive the tooth ring 4 to rotate on the outer surface of fixed ring 10, and the fixed mechanism 2 is driven to rotate.

[0042] The fixing mechanism 2 is mainly composed of a plurality of fixing buckles 201 rotatably arranged on one side of the fixing ring 3 and a plurality of tooth plates 203 movably arranged. One end of the fixing buckle 201 is rotatably arranged in the circular hole 15, the other end of the fixing buckle 201 penetrates the elastic rubber ring 9 and the fixing ring 10, and is inserted into the special-shaped groove 16. The internal shape of the special-shaped groove 16 perfectly matches the movement track of the fixing buckle 201 when rotating. A miniature spur gear 202 is fixedly sleeved on the outside of the fixing buckle 201. The miniature spur gear 202 is engaged with the rack 5 arranged in the inner ring of the tooth ring 4. Therefore, rotating the tooth ring 4 can drive the miniature spur gear 202 and the fixing buckle 201 to rotate to a preset progress. A torsion spring 207 is sleeved on the outside of the fixing buckle 201. The two ends of the torsion spring 207 are fixedly connected with the inside of the circular hole 15 and the side of the miniature spur gear 202 facing the circular hole 15, so that the fixing buckle 201 can automatically reset after being subjected to external force. The width of the fixing ring 10 and the elastic rubber ring 9 is higher than that of the tooth plate 203 and the side of the miniature spur gear 202 away from the fixing ring 3, so that the elastic rubber ring 9 can precisely seal the fixing ring 10 and the flange plate 13.

[0043] The sliding block 6 drives the tooth ring 4 to rotate, so that the rack 5 arranged in the inner ring of the tooth ring 4 drives the miniature spur gear 202 to rotate, and the fixing buckle 201 arranged in the circular hole 15 rotates to a preset angle and is completely inserted into the special-shaped groove 16 arranged on the surface of the flange plate 13. At this time, the torsion spring 207 is stretched, and the elastic rubber ring 9 fixed on the surface of the fixing ring 10 can seal the joint between the fixing ring 10 and the flange plate 13 when being attached to the flange plate 13.

[0044] Referring to Figure 1 Figure 3 , Figure 5 The surface of the tooth plate 203 is provided with an oval slot 204. A limiting rod 205 is movably arranged in the oval slot 204. The other end of the limiting rod 205 is fixed on the fixing ring 3, so that the tooth plate 203 can move longitudinally when being subjected to external force, and will not completely separate from the fixing ring 3. The bottom end of the tooth plate 203 is also fixedly provided with an extrusion rod 206. The inner ring of the extrusion rod 206 is fixedly provided with a sealing ring 7. The sealing ring 7 is made of a flexible material, which ensures the tightness of the sealing.

[0045] ​The micro spur gear 202 drives the toothed plate 203 and the oval slot 204 inside the toothed plate 203 to slide to the preset position outside the limiting rod 205, and then the extrusion rod 206 pushes the sealing ring 7 to be extruded inward, so that the diameter of the sealing ring 7 is smaller than the diameter of the inner wall of the flange plate 13, and therefore the sealing ring 7 can quickly enter the ring of the flange plate 13 along with the movement of the fixed ring 3, and then the sliding block 6 is released to make the torsion spring 207 rebound, and then the tooth ring 4 is rotated in the opposite direction, and then the micro spur gear 202 is reset inside the special-shaped slot 16, and the rebound of the sealing ring 7 can make the extrusion rod 206 reset, at this time, the outer surface of the sealing ring 7 is tightly attached to the inner wall of the flange plate 13, so that the fixed ring 10 and the flange plate 13 can be sealed again, and the sealing effect is better.

[0046] The flange plate 13 is provided with a recess 14 on the upper end of the side away from the elastic rubber ring 9, and the cover plate 11 is fixedly provided with a rotating shaft 12 on the upper end of the side close to the recess 14, the rotating shaft 12 is rotatably arranged on both sides of the inner cavity of the recess 14, so that the cover plate 11 can be flexibly opened or closed when needed, and the flange plate 13 is fixedly provided with a light and thin magnetic sheet 18 on the lower end of the same side, which can only provide a weak adsorption point for the cover plate 11, and the cover plate 11 can be easily blown open during the operation of the air conditioner.

[0047] When the air conditioner operates, the cold and hot air is transmitted to the air outlet through the inside of the air pipe 17, so that the cover plate 11 provided on one end of the air outlet is blown and rotated inside the recess 14 through the fixed rotating shaft 12 to drive the cover plate 11 to flip upward, so that the cold and hot air can be transmitted to the room, and when the air conditioner stops operating, the cover plate 11 is reset due to its own gravity and is adsorbed on the magnetic sheet 18 fixed on the surface of the flange plate 13.

[0048] The implementation principle of the air conditioner heat preservation structure in the embodiment is as follows: before use, the heat preservation cotton 1 is slid into the outside of the air pipe 17 through the fixed ring 3, and the sliding layer 8 reduces the friction and damage between the air pipe 17 and the heat preservation cotton 1; during use, the sliding block 6 is longitudinally pulled to drive the tooth ring 4 to rotate on the outer surface of the fixed ring 10, so that the rack 5 drives the micro spur gear 202 to rotate, drives the fixed buckle 201 arranged in the circular hole 15 to rotate and insert into the special-shaped slot 16 of the flange plate 13, and the torsion spring 207 is stretched, and the elastic rubber ring 9 seals the interfaces of the flange plate 13 and the fixed ring 3; the micro spur gear 202 also drives the toothed plate 203 and the oval slot 204 outside the limiting rod 205 to slide, so that the extrusion rod 206 pushes the sealing ring 7 to be smaller and enter the flange plate 13, and after the sliding block 6 is released, the torsion spring 207 is reset, the sealing ring 7 is tightly attached to the inner wall of the flange plate 13, and secondary sealing is realized; when the air conditioner operates, the cold and hot air blows the cover plate 11 to rotate, and when the air conditioner stops operating, the cover plate 11 is reset due to gravity and is adsorbed on the magnetic sheet 18.
