Abstract

The utility model relates to an electric force transmitting mechanic ventilating arrangement, which is suitable for the people to remove summer-heat and cool down in summer. The arrangement adopts a worm screw (gear wheel) gearing device and a link mechanism, converting the rotary movement of the output shaft of the electrical machine into a teetering movement to overcome the various considerable discomforts of the blown whirlwind brought to the people by the existing electric fan, and which is provided with a soft and natural wind force. The utility model has the advantages of appropriate air volume and high-usage of wind; power saving.

Description

Automatic-swing fan

The utility model is a kind of electric power---mechanically operated ventilation plant, be specially adapted to people relieve summer heat summer fall heat used.

At present commercially available electric fan all is to give birth to wind by the rotation of driven by motor flabellum, brings following shortcoming thus: 1, the wind that blows out of electric fan is stronger, and wind rotates, and this wind will produce discomfort on the person; What 2, electric fan blew out is continuous wind, also will make the people produce discomfort, although adopted electric fan to shake the head and the way of fitful wind control now, the frequency that is difficult to guarantee to blow the fitful wind on the person drops in the scope about making the comfortable per second of people once; 3, the wind that blows out of electric fan, wind-force is stronger.Air quantity is also bigger, gets a wherein very little part and blows on the person for making the comfortable employing electric fan of people way such as shake the head, although the frivolous thing that remaining wind can blow indoorly dances in the air to be touched, it is useless that heat is fallen in relieving summer heat of people.The waste of this wind energy is actually waste of electric energy, and this waste has caused the motor in the electric fan will select the bigger motor of power for use.

The purpose of this utility model is exactly in order to overcome the problem of above-mentioned existence, to design a kind of Automatic fan of simulating Hand swing fan.

Technical solution of the present utility model as shown in the figure.

Fig. 1 is the utility model structural representation;

Fig. 2 is the another kind of linkage structure schematic representation of the utility model.

In Fig. 1,2, motor 1 is fixedly mounted on the pallet 13, and worm screw (or gear) 2 is housed on its output shaft, worm screw (or gear) 2 composition deceleration device that is meshed with worm gear (or driven gear) 3. The place in the non-central hole on worm gear (or driven gear) 3 wheel faces and an end of connecting rod 4 are hinged, and certain on the other end of connecting rod 4 and the sleeve pipe 61: 16 is hinged. The lower end of casing support 5 is fixedly mounted on the pallet 13, and the upper end of casing support 5 and sleeve pipe 6 are hinged. This pin joint is fulcrum 17. Casing support 5 or be installed in the right side (such as Fig. 1) of worm screw (or gear) deceleration device, perhaps be installed in the left side (such as Fig. 2) of worm screw (or gear) deceleration device, make accordingly pin joint 16 or on the left side of fulcrum 17 sleeve pipe 6 (such as Fig. 1), on the sleeve pipe 6 that perhaps prolongs on fulcrum 17 right sides (such as Fig. 2).

The diameter of axle 18 is less than the center bore of worm gear (or driven gear) 3, the wheel face centre bore of worm gear (or driven gear) 3 is sleeved on the axle 18, and can rotate around axle 18, the inner of axle 18 is round platform rank, the diameter on these round platform rank is greater than the center bore of worm gear (or driven gear) 3. The round platform rank are fixed on the upper end of support 9, and perpendicular with support 9. The lower end of support 9 is fixed on the pallet 13, and the relative motion that worm gear (or driven gear) 3 and axle are 18 can also realize by at axle 18 bearing being installed. Fan 8 is palm-leaf fan, the bajiao banana shape fan of perhaps making for the light and thin material. The fan handle of fan 8 directly inserts in the sleeve pipe 6, and fixing by two bolts 7 on the sleeve pipe 6, the length of fan handle in sleeve pipe 6 is adjustable.

The arrangements for speed regulation 10 of motor 1 also are installed on pallet 13, button and the power switch 12 of regulating motor speed are installed on the surface of outer cover 11, the above and below of pallet 13 is a disc, and it can pass through positioning screwn 19 upper and lower transfers in vertical rod 14, to adjust the height of fan 8.Vertical rod 14 is a metal inner and outer sleeve structure, is placed with spring between interior pipe and outer tube.Its upper end is welded on the bottom surface of pallet 13, its lower end and base 15 welding.

Advantage of the present utility model is: 1, a burst of gentle breeze of Automatic fan fan-out, the soft nature of wind-force; 2, the frequency of fitful wind and the convenient control of big I, and all drop on blander scope; 3, the air quantity that is produced is suitable, can be used for relieving summer heat of people fully and fall heat, and therefore the wind energy utilization height that is produced promptly will reach same effect.The existing electric fan institute of this device consuming electric power is much smaller, and used motor 1 is also optional in the device uses lower-powered motor, thereby reduces cost.

Provide embodiment of the present utility model below in conjunction with Fig. 1:

When using Automatic fan, connect power supply, make motor 1 operation, drive worm screw (or gear) 2 with rotation speed n ₁Rotation is slowed down by worm screw (or gear) transmission device, makes worm gear (or driven gear) 3 with lower rotation speed n ₂(n ₂About 60 rev/mins) running, the connecting rod 4 on its wheel face and then pumps, and its frequency swings up and down around fulcrum 17 under the effect of connecting rod 4 for (n2)/60 sleeve pipe 6, and the fan 8 that is inserted in the sleeve pipe 6 is also followed with frequency (n ₂)/60 swing up and down.The wind that fan-out is soft.Regulate the length of fan handle in sleeve pipe 6 of fan 8, can change the amplitude that fan swings up and down, to satisfy the different needs of people to air quantity.

When needs change the hunting frequency of fan 8, press speed governing button 12, change motor speed by motor speed control device 10, make the rotation speed n of worm gear (or driven gear) 3 ₂Change, then frequency (the n that swings up and down of fan thereupon ₂)/60 have also just changed.

When adopting Automatic fan shown in Figure 2, can obtain same effect, principle is identical with Fig. 1.
