Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 6, a kind of small-sized fans, comprise base 1, motor is provided with in base, for increasing the heat sinking function of base, described base bottom is provided with the radiation hole 11 of more than 2, base top is fixed with a root post 2, rotatingshaft 3 is provided with in column, rotatingshaft drives by motor, rotatingshaft top is provided with Cylindrical Gear 31, rotatingshaft coaxial transmission has a rotating disk 4, during electric motor starting, drive dial rotation, disk axes place is provided with attachment post 41, be provided with tooth-like part 411 in attachment post to engage with Cylindrical Gear, rotating disk inside is hollow structure from tooth-like part radial direction outward, the outer side wall of rotating disk is vertically provided with falculate fan blade 42, as shown in fig. 1, outer side wall is evenly distributed with multiple fan blade, the air-supply of traditional fan blade one direction is changed into 360 degree of radial air-supplies while fan blade rotates, wind direction is driven to flow by fan blade during dial rotation, to realize the wind direction flowing of rotating disk surrounding, finally realize 360 degree to blow without dead angle, traditional fan needs when different amount scope is blown additionally to install a rotation system additional, to realize swing function, and without the need to installing this kind of rotational structure additional in this programme, the function toward surrounding air-supply has been realized during rotating disk own rotation, so relative to simpler traditional fan in structure, cost is little, and can also energy consumption be reduced.
As shown in Figure 3 to Figure 4, described column is fixed with annular round platform 21 below Cylindrical Gear, annular round platform is fixed with bearing 22, is provided with the bearing counterbore 413 holding bearing bottom described tooth-like part, and after installing bearing, the operating life of rotating disk increases greatly.
As shown in Figure 5 to Figure 6, in order to increase the cooling function of this programme in summer, described attachment post top is provided with the cavity 412 placing ice cube, the inwall of cavity is vertically provided with the ventilation slot 412a of more than 2, install above cavity and be provided with upper cover 5, the ice cube of cooling can be placed in cavity, ice cube ambient air flows out through ventilation slot, through the hollow structure of rotating disk, finally flow out by from the space in adjacent two panels fan blade, lower the temperature to surrounding environment through blowing of fan blade, upper cover can prevent ice melting water from throwing away from top again.Described cavity inner wall top is provided with annular slot 412b, annular slot is provided with limiting stopper 412b1, the annular buckle 51 mated with annular slot is provided with bottom described upper cover, annular snap buckles the breach 511 being provided with and holding limiting stopper, because rotating disk rotating speed when rotating is higher, if upper cover does not have limit function, easily depart from rotating disk under the influence of centrifugal force, there is annular buckle can be undertaken spacing by upper cover upper-lower position with mating of annular slot, and mating of breach and limiting stopper can prevent upper cover when high speed rotating and rotating disk rotates, upper cover is caused to occur to loosen, frozen water is avoided to flow out from the gap loosened.
In order to increase Security of the present utility model, described rotating disk outside is provided with cover body, cover body is fixedly made up of two points of cover bodies 61, described column is provided with limit dais 23 at medium position, be positioned over bottom described cover body on limit dais, increasing cover body can prevent the hand of some children from touching the fan blade of rotation, be also the installation and removal facilitating cover body, and limit dais carries out spacing to the upper-lower position of cover body by the structure of two points of cover body assemblings.A described point cover body is all provided with fixed feet 611 at the top of constant cross-section and bottom, and fixed feet is provided with through hole and passes for fastening screw, and the end face center of point cover body is provided with semicircle orifice 612, and semicircle orifice is also facilitate user to open upper cover.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
