The bottom of the storage frame 508 is fixedly provided with a triangular inclined block 87, the inside of the storage frame 508 is fixedly connected with a support net 88, and the other end of the support net 88 is fixedly connected with the inclined block 87; during operation, owing to have tilting block 87 and support net 88 in accomodating the frame 508 for can not be completely with accomodating the laminating mutually of frame 508 bottom after the ice-cube 513 is put into accomodating the frame 508, thereby prevent that ice-cube 513 from blocking up the honeycomb duct 84 of accomodating the frame 508 bottom and intaking, support net 88 plays to block ice-cube 513, makes there is the space between the water inlet of ice-cube 513 and honeycomb duct 84, conveniently intakes, and tilting block 87 is all to honeycomb duct 84 department after being the water in order to make things convenient for ice-cube 513 to melt.
Embodiment two:
As shown in fig. 8, in comparative example one, another embodiment of the present invention is:
The inner wall of the ventilation groove 505 is clamped with a filter screen 9, 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 of rectangle frame 502 for filter screen 9 block is in ventilation groove 505, lets filter screen 9 play dustproof and reduce the effect that the dust got into rectangle frame 502, avoids folding wheelchair 1 when outdoor use, had a large amount of dust and impurity to get into in the rectangle frame 502.
Working principle: when a person sits on the folding wheelchair 1, the motor 503 on the supporting plate 501 is started to enable the output end of the motor 503 to rotate with the fan blades 504, wind generated during rotation of the fan blades 504 is led out through the ventilation grooves 505 of the rectangular frame 502, and then the person sitting on the folding wheelchair 1 is blown and cooled, 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, and safety accidents are prevented, when the fan blades 504 rotate, the person touches by mistake, and therefore, when the person is too hot in summer, the first spring 512 restores the elasticity through the first spring 512 in the rectangular frame 502, the first spring 512 moves towards the opening of the rectangular frame 502 with the containing frame 508, the containing frame 508 slides through the sliding blocks 507 in the sliding grooves 506, after the containing frame 508 reaches the opening of the rectangular frame 502, the ice cubes 513 are placed in the containing frame 508, and the containing frame 508 receives the gravity of the ice cubes 513, the containing frame 508 is reset through the sliding block 507, so that the magnet 510 at the bottom of the sliding block is adsorbed by the iron sheet 511 in the sliding groove 506, and then the containing frame 508 is fixed again, at this time, the containing frame 508 is positioned in front of the fan blade 504, when the fan blade 504 blows, wind of the fan blade 504 is blown out again through the ventilation hole 509 and the ice block 513, so that the hot wind blown out by the fan blade 504 is cooled, the hot wind blown out by the fan blade 504 becomes cold wind, thereby achieving the effect of further reducing the wind temperature, the comfort in use is further improved, when the containing frame 508 moves towards the opening of the rectangular frame 502, the bump 516 of the cover plate 514 at the top of the containing frame 508 is contacted with the rectangular block 517, and after the containing frame 508 continues to move towards the opening of the rectangular frame 502, the rectangular block 517 rotates and extrudes the bump 516 and the cover plate 514 towards the direction of the containing frame 508, and then after the containing frame 508 reaches the opening of the rectangular frame 502, the containing frame 508 is opened, thereby facilitating the placement of the ice blocks 513 into the containing frame 508, after the containing frame 508 is reset, the cover plate 514 is not extruded and can be reset, at this time, the heat preservation cotton 515 at the bottom of the cover plate 514 plays the roles of preserving heat of the ice blocks 513 and delaying melting, thereby facilitating the longer use of the ice blocks 513, after the containing frame 508 reaches the opening of the rectangular frame 502, the inclined guide plate 63 plays the roles of guiding and facilitating 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 moves towards the guide plate 63 along with the connecting plate 62, the connecting plate 62 rotates together with the second spring 64 after contacting the guide plate 63, the guide plate 63 seals the opening of the rectangular frame 502, thereby preventing sundries from falling into the rectangular frame 502 after sealing, the guide plate 63 is still inclined, the closed guide plate 63 is inclined to prevent dust and dirt from accumulating on the surface, when the wind blown by the fan blade 504 reaches the ventilation groove 505 and 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 and between the connecting ball 73 and the guide block 72, and further the cold wind blown by the fan blade 504 is convenient to flow out, so that the surface blown by the cold wind is wider, a better cooling effect is achieved, because the guide block 72 is inclined, dust and dirt can accumulate on the surface of the guide block 72, the accumulated dust and dirt can drop out through the dredging groove 75, and when the accumulated dust and dirt excessively exist, the blocking is caused, so that when the connecting ball 73 slides along the guide block 72, the connecting ball 73 can squeeze the dredging rod 77, the dredging rod 77 slides up and down with the inserted rod 78, the arc-shaped inserted rod 78 can better drive the blocked dirt to move, thereby play the effect of mediation groove 75, prevent that dust and debris from piling up too much back and causing the jam of mediation groove 75, after using folding wheelchair 1, because the outdoor too hot in summer, folding wheelchair 1's soft cushion 4 has sweat stain, this moment need in time clean, start electric putter 81 in rectangular frame 502, electric putter 81 carries clean cloth 82 and remove, make clean cloth 82's surface and folding wheelchair 1's soft cushion 4 contact, clean soft cushion 4 through the roll of clean cloth 82, thereby keep folding wheelchair 1's clean, after the ice-cube 513 in the storage frame is melted, the water that melts can flow into water tank 85 through honeycomb duct 84, and electric putter 81 carries clean cloth 82 when reset, rubber material ejector pin 83 on electric putter 81 can jack-up water tank 85 bottom's case lid 86, thereby let water in the water tank 85 flow out and drip on clean cloth 82, thereby wet clean cloth 82, make clean cloth 82 further clean soft cushion 4 on folding wheelchair 1, because have tilt block 87 and supporting network 88 in the storage frame 508, make 513 put into in honeycomb duct 84 and not take in water tank 508 and can not take in water tank 84 completely, and prevent that water from flowing into the water inlet 513 from taking place in the air tank 84, the water inlet 513 is in order to prevent that water from having the hole 513 from flowing into the bottom 84, and water inlet 84 is easy to keep up.
The foregoing has shown and described the basic principles, principal features and advantages of the invention.
