Description

A New Type of Rotating and Shaking Head Mechanism

technical field

The utility model relates to a head shaking device of an electric appliance, in particular to a novel rotating head shaking mechanism.

Background technique

At present, with the improvement of living standards, consumers put forward higher requirements on the functions and operations of household appliances. Some household appliances, such as electric fans, heaters, air conditioners, etc., have a shaking head function to bring better hair blowing. Heat dissipation or heating effect, but the existing oscillating head structure is usually assembled by oscillating head motor, turntable, connecting rod, central rotating shaft and other components. Low, complex structure, long-term work will affect the stability of the structure, reduce the service life, and the manufacturing cost is also high.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a new type of rotating and oscillating mechanism, which adopts the combined structure of the crankshaft and the limit groove to realize the function of oscillating the head. The structure is simpler and more practical, the use of parts is reduced, and the production cost is greatly reduced.

The technical scheme that the utility model solves its technical problem adopts is:

A new type of oscillating head mechanism, including a rotating seat, an oscillating motor, a crankshaft and a base, a turntable is provided at the bottom of the rotating seat; The hole is positioned and connected with the rotary head, and the crankshaft is also provided with a rotary handle that deviates from the axis of the crankshaft; the base is provided with a circular groove matching the rotary table, and the circular groove is provided with a limiting groove for limiting the movement of the crankshaft; The rotating base is rotatably placed on the base, the rotating head is connected to the crankshaft, and the rotating handle of the crankshaft is placed in the limiting groove. During the rotation of the crankshaft, the rotating handle will move back and forth along the limiting groove, and the shaking head motor is The eccentric torque rotates to drive the rotating seat to rotate, realizing the function of shaking the head.

As an improvement of the above technical solution, the shaft hole is a non-circular shaft hole and matches with the rotator so that the rotator and the crankshaft rotate synchronously.

As a further improvement of the above technical solution, the limiting groove is a bar-shaped structural groove, and the width of the limiting groove is equal to the diameter of the rotating handle.

As a further improvement of the above technical solution, a guide groove is provided in the circular groove corresponding to the guide post provided on the turntable.

The beneficial effects of the utility model are: the oscillating head motor of the eccentric head structure is used to rotate the crankshaft. Due to the action of the eccentric moment, the crankshaft moves along the limit groove while rotating, and the oscillating head motor itself is also affected by the rotating force to drive the crankshaft. The revolving seat rotates. Compared with the previous shaft-type oscillating head structure, the oscillating head mechanism of the utility model reduces the use of parts and structural friction. The structure is simpler and more practical, stable and firm, and the structural design is reasonable and novel, which greatly reduces production costs. , but also improve assembly efficiency.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the split structural representation of the utility model;

Fig. 2 is the structural representation of the crankshaft in the utility model.

Detailed ways

Referring to Figure 1 and Figure 2, the utility model provides a new type of rotating head shaking mechanism, which is different from the previous shaft-type shaking head device, and is widely applicable to household appliances that need shaking head function, such as electric fans, heaters, etc. Concrete structure comprises rotating base 1, shaking head motor 2, crankshaft 3 and base 4, and rotating base 1 bottom is provided with turntable 11; There is a shaft hole 31 connected to the rotor 21, the shaft hole 31 is a non-circular shaft hole 31 and matched with the rotor 21 to realize synchronous rotation, the base 4 is provided with a circular groove 41 matching the turntable 11, through which the turntable 11 Matching and combining with the circular groove 41 makes the rotating base 1 rotatably placed on the base 4 .

In the above structure, the crankshaft 3 is also provided with a turning handle 32 that deviates from the axis of the crankshaft 3, and the circular groove 41 is provided with a limiting groove 42. When installing, the turning handle 32 is placed in the limiting groove 42. In this embodiment , The limiting groove 42 is a strip-shaped structural groove, and the width of the limiting groove 42 is set just enough to insert the rotating handle 32, so that the rotating handle 32 is more stable when moving. In order to enhance the stability of the oscillating mechanism, during the oscillating process of the rotating base 1 , the guide post provided on the turntable 11 moves along the guide groove provided in the circular groove 41 , which can make the oscillating steering more stable and smooth.

The utility model adopts the eccentric rotating head 21 structure of the oscillating motor 2 linked to the crankshaft 3 to rotate. When working, the oscillating motor 2 linked to the crankshaft 3 rotates. Due to the effect of the eccentric moment, the turning handle 32 will move along the limit when the crankshaft 3 rotates. The slot 42 moves, and the oscillating head motor 2 itself is also subjected to the rotational force to drive the rotatable seat 1 to rotate to realize the oscillating function. Compared with the previous shaft-type oscillating structure, the oscillating head mechanism of the present invention reduces the use of parts and reduces production costs. The cost is reduced, the friction of the structure is reduced, the structure is simpler and more practical, stable and firm, the design is reasonable and novel, and the assembly efficiency is also improved.

The above is only a preferred embodiment of the utility model, and the utility model is not limited to the structure of the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by the same means, it should belong to the protection of the utility model scope.
