Abstract
The utility model discloses a prevent dust fall formula electric fan, including governor switch and electric fan body, the electric fan body includes three blade, including dog, cavernosum, transmission structure, race, spring and fixed block on the single blade, the race sets up the upper and lower surface at the blade, drive mechanism includes gyro wheel, axle, the gyro wheel is placed in the race, rolls in the race, the axle is connected with bearing for the gyro wheel, the outside parcel cavernosum of axle, the cavernosum passes through the coupling spring and is connected with the inner fixed block of blade, the dog sets up the outer end on the blade surface for prevent that the cavernosum from being thrown away because of the centrifugal force effect is too big. The utility model discloses a through fan pivoted centrifugal force promotion cavernosum, make the cavernosum slide on the surface at the blade and clean the dust, reach the automatic effect of cleaning blade deposition function of suspension type electric fan.
Description
Technical field
The utility model relates to a kind of dust fall formula electric fan, belongs to household appliance technical field.
Background technique
In life, suspended electric fan long term exposure makes vane dust deposition not easy cleaning in outside, and conventional cleaning means have two kinds: one fan blade is taken off clean, and install after cleaning out again and go back, but this kind of Measures compare is loaded down with trivial details, efficiency is low; Another kind directly cleans suspended electric fan blade, because blade can freely rotate in the plane, cause this kind of method can bring danger to high-rise working personnel, the dust that the personnel that simultaneously clean are easy on suction fan blade, it is healthyly had a negative impact.
Model utility content
The utility model solves suspended electric fan long term exposure makes vane dust deposition not easy cleaning problem in outside, conventional cleaning means have two kinds: one fan blade is taken off clean, install after cleaning out again and go back, but this kind of Measures compare is loaded down with trivial details, efficiency is low; Another kind directly cleans suspended electric fan blade, because blade can freely rotate in the plane, cause this kind of method can bring danger to high-rise working personnel, the dust that the personnel that simultaneously clean are easy on suction fan blade, it is healthyly had a negative impact.The utility model is the centrifugal force pulls foam body by fan turns, makes foam body carry out slip over the paddle and carrys out wiping dust, reach the effect of suspended electric fan automatic cleaning vane dust deposition function.
Technical characteristics of the present utility model is as follows:
A kind of anti-dust fall formula electric fan, comprise governor switch (7) and electric fan body, described electric fan body comprises three blades (2), described individual blade (2) comprises block (1), foam body (3), drive mechanism (4), race (5), spring (6) and fixed block (9); Described race (5) is arranged on the upper and lower surface of blade (2), described driving mechanism (4) comprises roller (42), axle (43), described roller (42) is placed in race (5), roll in race (5), described axle (43) is connected with bearing with roller (42), the outer wrap foam body (3) of described axle (43), described foam body (3) is connected by the fixed block (9) that linking springs (6) is inner with blade (2); Described block (1) is arranged on the outer end on blade (2) surface, is thrown out of because centrifugal action is excessive for preventing foam body (3).
Above-mentioned electric fan also comprises lateral retaining plate (8), and for being connected on blade (2) upper and lower surface side, fixed idler whell (42) slides in race (5).
Above-mentioned axle (43) and foam body (3) are dismountable, pull down foam body (3) clean when fan is out of service.
The beneficial effect that the utility model reaches:
1, the problem of suspended electric fan blade surface dust stratification not easy cleaning is solved;
2, the operational sequence of conventional cleaning suspended electric fan is eliminated, self centrifugal force Automatic clearance vane dust deposition that Appropriate application electric fan rotates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure partial amplification profile of driving mechanism.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of anti-dust fall formula electric fan, comprise governor switch 7 and electric fan body, electric fan body comprises three blades 2, individual blade 2 comprises block 1, foam body 3, drive mechanism 4, race 5, spring 6 and fixed block 9; Race 5 is arranged on the upper and lower surface of blade 2, and driving mechanism 4 comprises roller 42, axle 43, and roller 42 is placed in race 5, roll in race 5, axle 43 is connected with bearing with roller 42, the outer wrap foam body 3 of axle 43, and foam body 3 is connected by the fixed block 9 of linking springs 6 with blade 2 the inner; Block 1 is arranged on the outer end on blade 2 surface, is thrown out of because centrifugal action is excessive for preventing foam body 3.
Above-mentioned electric fan also comprises lateral retaining plate 8, and for being connected on blade 2 upper and lower surface side, fixed idler whell 42 slides in race 5.
Above-mentioned axle 43 is dismountable with foam body 3, pulls down foam body 3 clean when fan is out of service.
When wind speed shelves got to by speed regulator, the roller 42 that the centrifugal force due to electric fan rotation generation makes and the active force slided in axle 43 oriented block 1 direction, thus realize the slip of foam body 3 at blade surface, realize the cleaning of blade surface dust stratification.When speed regulator get to close shelves time, under the elastic force of spring 7 and the centrifugal force acting in conjunction that progressively reduces because electric fan is out of service, foam body 3 and the axle 43 connected, be rolled to by roller 42 position that spring stretches naturally in race 5.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
Claims (3)
1. an anti-dust fall formula electric fan, it is characterized in that: comprise governor switch (7) and electric fan body, described electric fan body comprises three blades (2), described individual blade (2) comprises block (1), foam body (3), drive mechanism (4), race (5), spring (6) and fixed block (9); Described race (5) is arranged on the upper and lower surface of blade (2), described driving mechanism (4) comprises roller (42), axle (43), described roller (42) is placed in race (5), roll in race (5), described axle (43) is connected with bearing with roller (42), the outer wrap foam body (3) of described axle (43), described foam body (3) is connected by the fixed block (9) that linking springs (6) is inner with blade (2); Described block (1) is arranged on the outer end on blade (2) surface, is thrown out of because centrifugal action is excessive for preventing foam body (3).
