Example two:
as shown in fig. 8, a first comparative example, in which another embodiment of the present invention is:
a filter screen 9 is clamped on the inner wall of the ventilation groove 505, and the upper end and the lower end of the filter screen 9 are attached to the two groups of hanging plates 71; during operation, through installing filter screen 9 in the ventilation groove 505 department at rectangular frame 502 for filter screen 9 block is in ventilation groove 505, lets filter screen 9 play dustproof and reduces the effect that the dust got into rectangular frame 502, avoids folding wheelchair 1 when the outdoor use, has a large amount of dusts and impurity to get into in the rectangular frame 502.
The working principle is as follows: when a person sits on the folding wheelchair 1, the output end of the motor 503 drives the fan blades 504 to rotate by starting the motor 503 on the supporting plate 501, wind generated when the fan blades 504 rotate is led out through the ventilation grooves 505 of the rectangular frame 502, and then the person on the folding wheelchair 1 is blown to cool, so that the person sitting on the folding wheelchair 1 feels comfortable, the rectangular frame 502 plays a role of covering the fan blades 504 and protecting the person, the fan blades 504 are prevented from being touched by mistake when rotating, so that a safety accident is caused, when outdoor is too hot in summer, the first spring 512 in the rectangular frame 502 recovers elasticity, the first spring 512 drives the containing frame 508 to move towards the opening of the rectangular frame 502, the containing frame 508 slides through the sliding block 507 in the sliding groove 506, when the containing frame 508 reaches the opening of the rectangular frame 502, ice blocks 513 are placed in the containing frame 508, and the containing frame 508 receives the gravity of the ice blocks 513, the receiving frame 508 is reset through the sliding block 507, so that the magnet 510 at the bottom of the sliding block and the iron sheet 511 in the sliding chute 506 are attracted, the receiving frame 508 is further fixed, the receiving frame 508 is located in front of the fan blade 504, when the fan blade 504 is blown, the air of the fan blade 504 is blown out through the air vent 509 and the ice block 513, and the hot air blown out by the fan blade 504 is cooled, so that the hot air blown out by the fan blade 504 is changed into cold air, the effect of further reducing the air temperature is achieved, the comfort in use is further improved, when the receiving frame 508 moves towards the opening of the rectangular frame 502, the protrusion 516 of the cover plate 514 at the top of the receiving frame 508 is in contact with the rectangular block 517, and after the receiving frame 508 continues to move towards the opening of the rectangular frame 502, the rectangular block 517 rotates and extrudes the protrusion 516 and the cover plate 514 towards the direction of the receiving frame 508, and when the receiving frame 508 reaches the opening of the rectangular frame 502, the receiving frame 508 is opened, therefore, the ice blocks 513 are conveniently placed into the containing frame 508, after the containing frame 508 is reset, the cover plate 514 is not squeezed and can be reset, the heat insulation cotton 515 at the bottom of the cover plate 514 can insulate the heat of the ice blocks 513 and delay melting, the ice blocks 513 can be conveniently used for a longer time, after the containing frame 508 reaches the opening of the rectangular frame 502, the inclined guide plate 63 can guide the flow and facilitate the ice blocks 513 to slide into the containing frame 508, after the ice blocks 513 are placed and the containing frame 508 is reset, the electric cylinder 61 in the rectangular frame 502 is started, the electric cylinder 61 drives the connecting plate 62 to move towards the guide plate 63, the connecting plate 62 contacts the guide plate 63 and drives the connecting plate 62 to rotate together with the second spring 64, the guide plate 63 seals the opening of the rectangular frame 502, so that sundries are prevented from falling into the rectangular frame 502, the guide plate 63 is still inclined after the sealing, the guide plate 63 is inclined to prevent dust and dirt from being accumulated on the surface, when the wind blown by the fan blade 504 reaches the ventilation groove 505, the wind also reaches the guide block 72, the wind blows the connecting ball 73, so that a gap is formed between the connecting ball 73 and the ventilation groove 505 as well as between the connecting ball 72 and the guide block 72, and further, the cold wind blown by the fan blade 504 can flow out conveniently, the surface blown by the cold wind is wider, and therefore, a better cooling effect is achieved, because the guide block 72 is inclined, dust and dirt can be accumulated on the surface of the guide block 72, the accumulated dust and dirt can drop out through the dredging groove 75, and blockage can be caused when too much dirt is accumulated, so when the connecting ball 73 slides along the guide block 72, the connecting ball 73 can extrude the dredging rod 77, the dredging rod 77 drives the inserting rod 78 to slide up and down, the arc-shaped inserting rod 78 can better drive the blocked through groove to move, so that the dredging groove 75 is dredged, and blockage of the dredging groove 75 is prevented from being caused after too much dust and dirt is accumulated, after the folding wheelchair 1 is used, because the outdoor environment is too hot in summer, sweat stains can be generated on the soft cushion 4 of the folding wheelchair 1, and cleaning needs to be performed timely, the electric push rod 81 in the rectangular frame 502 is started, the electric push rod 81 drives the cleaning cloth 82 to move, so that the surface of the cleaning cloth 82 is in contact with the soft cushion 4 of the folding wheelchair 1, the cleaning cloth 82 rolls to clean the soft cushion 4, the tidiness of the folding wheelchair 1 is kept, after ice blocks 513 in the storage frame 508 are melted, the melted water flows into the water tank 85 through the guide pipe 84, and when the electric push rod 81 drives the cleaning cloth 82 to reset, the ejector rod 83 made of rubber materials on the electric push rod 81 can push the box cover 86 at the bottom of the water tank 85 open, so that the water in the water tank 85 flows out and drops on the cleaning cloth 82, the cleaning cloth 82 is wetted, and the cleaning cloth 82 can further clean the soft cushion 4 on the folding wheelchair 1 conveniently, because the storage frame 508 is internally provided with the inclined block 87 and the support net 88, the ice blocks 513 cannot be completely attached to the bottom of the storage frame 508 after being placed into the storage frame 508, so that the ice blocks 513 are prevented from blocking the water inlet of the guide pipe 84 at the bottom of the storage frame 508, the support net 88 blocks the ice blocks 513, a gap is formed between the ice blocks 513 and the water inlet of the guide pipe 84, water can be conveniently fed, and the inclined block 87 is convenient for the ice blocks 513 to be melted to be water and then flow to the guide pipe 84.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
