Desk-top floor model dual purpose fan
Technical fieldThe utility model relates to for the pumping installations that ventilates, and working fluid is air, particularly relates to automatically changing the pumping installations of sending direction of air, relates in particular to desk-top floor model dual purpose fan.
Background techniqueElectric fan is a kind of widely used household electric appliance, and form has varied, but mainly is two kinds of forms, i.e. table fan and pedestal fan.Prior art table fan height is low, is fit to be put in table top, the first-class use of bed, is fit to the low level air-supply; The prior art pedestal fan has higher supporting frame between its fan body part and base, is suitable for placing on the ground, and high-order air-supply, generally the supporting frame of this type of pedestal fan can be regulated height, changes the air-supply height.
Described table fan can be placed on the air-supply of desired location low level because of highly low; And described pedestal fan height is high, be fit to the air-supply of higher position, although supporting frame can be regulated height, but with highly be reduced to minimum after also or far above table fan, simultaneously because the size of its base is larger, so existing pedestal fan can not directly be placed on desktop as table fan or ground cashier's office in a shop uses.
The model utility contentThe technical problems to be solved in the utility model be to avoid above-mentioned the deficiencies in the prior art part and design produce a kind of simple in structure, the desk-top floor model dual purpose fan of dual-use.
The present invention is that to solve the problems of the technologies described above the technological scheme that proposes be a kind of desk-top floor model dual purpose fan, comprise fan body, support tube and base, described support tube is connected to integral body with base removedly with fan body, also comprise the permanent magnet sucker, this sucker is hinged on respectively on the scaffold on the left and right two column tops of described support tube; Described fan body is adsorbed on the sucker of described scaffold by the suitable adsorption locating device of arranged on left and right sides on it and described permanent magnet sucker, becomes floor-type fan; The bottom of described fan body is provided with leg, and this leg is installed in the fan body bottom groove by elastic device; When fan body is moved apart and when using as bracker fan, uses as bearing pulling out half-twist in the groove of described leg by the fan body bottom from described support tube; On described fan body is adsorbed in the permanent magnet sucker of described support tube, when using as floor-type fan, pushes in the described groove after half-twist is retracted again with described leg and disappear.
Described scaffold is manually to be installed in slippingly up and down left and right two columns of described support tube upper end.
Described fan body is with respect to the luffing angle of described support tube, by described permanent magnet sucker " hinged " in this scaffold mode and can regulate.
Described permanent magnet sucker comprise cylindrical shell and accommodating in the inner, can be among this cylindrical shell the strip permanent magnet of axis rotation; The knob that is connected as one with described permanent magnet is positioned at described cylindrical shell outside;
Described cylindrical shell has a magnetic layer not, this not magnetic layer described cylindrical shell axially is divided into two magnetic conduction districts symmetrically; This not magnetic layer have a side to be positioned at adsorption locating device surface of contact place with described fan body; When described fan body was adsorbed in described permanent magnet sucker, turning knob made the magnetic pole of described permanent magnet just point to cylindrical shell two magnetic conduction districts, thereby described fan body tightly is adsorbed on the sucker; In the time of described fan body will being removed from described permanent magnet sucker, turning knob, the magnetic pole of described permanent magnet point to the not magnetic layer of described cylindrical shell, and then described fan body breaks away from this permanent magnet sucker then.
Described adsorption locating device comprises the locating piece of block soft magnetic material and magnetic conductive material, this locating piece with described soft magnetic material ferropexy in the left and right sides of described fan body back cabinet.
Compare with prior art, the invention has the beneficial effects as follows: realize that simple in structure, easy to use, economical and practically a fan is dual-purpose.

EmbodimentBelow, further set forth the present invention in conjunction with the preferred embodiment shown in each accompanying drawing.
Referring to Fig. 1 to 9, the present invention's preferred embodiment is design, a kind of desk-top floor model dual purpose fan of manufacturing, comprise fan body 1, support tube 3 and base 2, removable and base 2 is connected to integral body to described support tube 3 with fan body 1, also comprise permanent magnet sucker 4, this permanent magnet sucker 4 is hinged on respectively on the scaffold 32 on described support tube 3 left and right two column tops; Described fan body 1 is decided device 16 by the 4 suitable absorptions of its arranged on left and right sides and described permanent magnet sucker, is adsorbed on the permanent magnet sucker 4 of described scaffold 32, becomes floor-type fan; The bottom of described fan body 1 is provided with leg 5, and this leg 5 is installed in fan body 1 bottom groove by elastic device 8; When fan body 1 is removed when using as bracker fan from described support tube 3, use as bearing pulling out half-twist in the groove of described leg 5 by fan body 1 bottom; On described fan body 1 is adsorbed in the permanent magnet sucker 4 of described support tube 3, when using as floor-type fan, pushes in the described groove after half-twist is retracted again with described leg 5 and disappear.
Described scaffold 32 is manually to be installed in slippingly up and down described support tube 3 left and right two columns upper ends.
Described fan body 1 is with respect to the luffing angle of described support tube 3, by described permanent magnet sucker 4 " hinged " in this scaffold 32 mode and can regulate.
Referring to Fig. 4 to Fig. 9, described permanent magnet sucker 4 comprise cylindrical shell 41 and accommodating in the inner, can be among this cylindrical shell 41 strip permanent magnet 42 of axis rotation; The knob 43 that is connected as one with described permanent magnet 42 is positioned at described cylindrical shell 41 outsides; Described cylindrical shell 41 has a magnetic layer 410 not, this not magnetic layer 410 described cylindrical shell 41 axially is divided into two magnetic conduction districts 411,412 symmetrically; This not magnetic layer 410 have a side to be positioned at adsorption locating device 16 surface of contact 419 places with described fan body 1; When described fan body 1 was adsorbed in described permanent magnet sucker 4, turning knob 43 made the magnetic pole of described permanent magnet 42 just point to 41 liang of magnetic conduction districts 411 of cylindrical shell, 412, thereby described fan body 1 tightly is adsorbed on the sucker 4; In the time of described fan body 1 will being removed from described permanent magnet sucker 4, turning knob 43, the magnetic pole of described permanent magnet 42 points to the not magnetic layer 410 of described cylindrical shell 41, then described fan body 1 breaks away from these permanent magnet sucker 4 described two magnetic conduction districts 411 then, the good soft magnet of 412 employing magnetic conductivity is made, described not magnetic layer 410 is to adopt non-magnet_conductible material, makes such as brass.
In this example, described adsorption locating device 16 comprises the locating piece 162 of block soft magnetic material 161 and magnetic conductive material, and this locating piece 162 is fixed in described soft magnetic material iron 161 left and right sides of described fan body 1 back cabinet.
