The following description contains various specific details to aid in this understanding, but these should be considered exemplary only. Moreover, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
The utility model is described in further detail below with reference to fig. 1 and 2:
the utility model relates to an electric fan, which comprises a shell 3 and a fixing seat 1 which are connected with each other. The casing 3 is cylindric, is close to cylindric casing 3's below surface and is equipped with annular antislip strip 20, and antislip strip 20 can conveniently take whole electronic fan, plays the effect of safe gripping and moving. A motor 2-driven linkage mechanism and a pair of intermeshing profile drive wheels 24 connected between the motor 2 and the linkage mechanism are provided within the housing 3. In this example, the linkage comprises a crank link 23 and an 'L' -shaped link 21. The special-shaped driving wheel 24 is in a pawl shape, the arc line part 25 of the pawl-shaped special-shaped driving wheel 24 is provided with gear teeth, and the straight line part 26 of the pawl-shaped special-shaped driving wheel 24 is in a straight shape. The pawl-shaped special-shaped driving wheel 24 is in meshed transmission with each other through gear teeth of the arc line part 25, and a mutual quick poking effect is formed through the straight line part 26. One end of the crank connecting rod 23 is eccentrically connected to the output pawl-shaped special-shaped driving wheel, the other end of the crank connecting rod 23 is connected with the horizontal end of the L-shaped connecting rod 21, and the vertical end of the L-shaped connecting rod 21 extends out from the side surface of the shell 3 and is connected with the handle 50 of the fan 5. The whole fan 5 outside the shell 3 is kept transverse, and the fan 5 is reciprocally and flaring in the transverse direction under the drive of the L-shaped connecting rod 21. For convenient control and speed regulation, a control panel 6 is also arranged on the surface of the shell 3, and the control panel 6 is in signal communication with the motor 2.
In order to further improve the stability, besides the bottom of the shell 3 is provided with a fixing seat 1, in this example, the bottom of the fixing seat 1 is also provided with a sucking disc 10. The sucker 10 can realize rapid adsorption with external supports, and ensures the stability of the whole structure in the flaring process.
When the electric fan is specifically used, firstly, the whole electric fan is adsorbed on a proper position through the sucking disc 10, then the flaring speed and the flaring time are set through the control panel 6, and finally, the motor 2 is started, and the motor 2 drives the two mutually meshed pawl-shaped special-shaped driving wheels 24 to start meshing transmission. When the pawl-shaped special-shaped driving wheel 24 in meshed transmission is transmitted on the gear teeth of the arc line part 25, the fan 5 outside the shell 3 can be driven to do uniform horizontal transverse swing through the eccentric crank connecting rod 23 and the L-shaped connecting rod 21; when the transmission process of the two pawl-shaped special-shaped transmission wheels 24 enters the flat end, a rapid poking transmission effect is formed between the two special-shaped transmission wheels 24 due to sudden change of the stroke, and the outer fan 5 of the shell 3 is driven by the crank connecting rod 23 and the L-shaped connecting rod 21 to form a rapid flaring at the tail end of the flaring stroke, so that the manual flaring fan process is fully simulated, the flaring intensity is enhanced due to change of the rhythm, and the actual flaring requirement is met.
The foregoing is illustrative of the present utility model and is not to be construed as limiting thereof, but rather, any modification, equivalent replacement, improvement or the like which comes within the spirit and principles of the present utility model are intended to be included within the scope of the present utility model.
