Background

The electric stirrer drives the stirring tool to rotate through the driving mechanism, so that different functions such as mixing, beating, blending or whipping can be realized for different food products or formulas.

For example, as an electric stirrer of an egg beater, it is equipped with an egg beating roller to achieve an egg beating function. In a conventional egg beater, a worm is connected to an output shaft of a motor, and the worm are matched to reduce speed, so that only one speed reduction ratio is required and is constant. After the speed is reduced, a certain rotating speed is output to the transmission piece through the worm wheel.

To achieve speed regulation, electronic speed change control is typically used. However, in both the simple shift control in which the shift position is divided into a plurality of shift positions and the continuous shift control, the rotation speed of the motor is controlled by changing the voltage. This kind of speed change results in a large drop in output torque and affects the whipping effect. If the electric stirrer is used for stirring the dough and other operations, the stirring effect is poor, and the motor is easy to overload and generate heat, so that the service life of the product is influenced.

In a hand-held electric mixer disclosed in CN201310144037.7, the above problem is improved, and the speed change mechanism has a first gear ratio and a second gear ratio. The electric agitator can select which gear to engage by sliding the clutch disc of the selector mechanism up and down to obtain the first gear ratio or the second gear ratio, respectively. Adopt this kind of electric mixer, need shift according to the function of difference when practical application, not only product structure is complicated but also operation experience is not good. Its application is limited.

In the present embodiment, the main function of the electric mixer is to beat eggs, and therefore the reduction assembly (2) as a driving mechanism has two outputs (4) for connecting a mixing tool (not shown in the figures). As shown in fig. 2, the two output terminals (4) are arranged left and right with respect to the motor output shaft.

As shown in fig. 4, in the present embodiment, a first transmission member (201) and a second transmission member (202) which are coaxially output are provided at each output end (4). Wherein, the first reduction gear ratio is provided from the motor output shaft to the first transmission piece (201), and the second reduction gear ratio is provided from the motor output shaft to the second transmission piece (202). Wherein the first reduction ratio is different from the second reduction ratio.

The first transmission piece (201) and the second transmission piece (202) have different output rotating speeds.

Since the motor output shaft has different reduction ratios to the first transmission member (201) and the second transmission member (202), the first transmission member (201) and the second transmission member (202) have different output torque forces/torques. When the stirring tool is used, a user can connect the stirring tool to the first transmission piece (201) of the output end (4) or the second transmission piece (202) of the output end (4) according to specific conditions, so that different output torque forces can be obtained.

According to the specific embodiment of the application, the speed reduction assembly comprises a worm (5), two first gears (6), two second gears (7) and at least one speed reduction wheel (8).

Wherein, the worm (5) is arranged on the output shaft of the motor. The two first gears (6) are respectively arranged on two sides of the worm (5).

The first gear (6) is meshed with the worm (5) to form a first-stage speed reducing mechanism. The first-stage reduction mechanism has a first reduction ratio. The first gear (6) is fixedly connected with the first transmission piece (201) on the corresponding side and outputs a first rotating speed to the first transmission piece (201).

The two second gears (7) are respectively fixedly connected with the second transmission pieces (202) on the corresponding sides.

The speed reducing assembly of the specific embodiment of the application comprises at least one speed reducing wheel (8). An input end gear of the reduction gear (8) is meshed with the first gear (6), and an output end gear of the reduction gear (8) is meshed with the second gear (7). The worm, the first gear, the reduction gear and the second gear are sequentially driven and form a second reduction ratio of the reduction assembly together.

When the motor runs, the first transmission piece (201) and the second transmission piece (202) rotate simultaneously and have different output rotating speeds.

Wherein, the central axis of the deceleration wheel (8) is parallel to the central axis of the output end.

The reduction gears are respectively meshed with the first gear and the second gear to finally form at least two-stage reduction mechanisms.

In a particular embodiment, the reduction wheel (8) is adapted to mesh with the first gear (6) and the second gear (7) respectively to form a second reduction and a third reduction. The reduction gear (8) comprises a third gear (81) and a fourth gear (82) which are fixed on the same positioning shaft (83). The third gear (81) is meshed with one of the first gears (6) to form a second-stage speed reducing mechanism, and the fourth gear (82) is meshed with one of the second gears (7) to form a third-stage speed reducing mechanism.

Wherein, the speed reducing component (2) is fixed with the motor (1) through a fixed bracket. More specifically, the fixing bracket includes a first bracket (31) and a second bracket (32) disposed in an up-down direction.

According to the specific embodiment of the application, the first transmission piece (201) and the second transmission piece (202) are on the same axis, and the first transmission piece and the second transmission piece rotate simultaneously and do not interfere with each other. In a particular embodiment, as shown in fig. 3 and 4, both the first transmission member (201) and the second transmission member (202) are arranged up and down. The first transmission piece (201) is arranged on the upper part, and the second transmission piece (202) is arranged on the lower part. The second gear (7) and the fourth gear (82) are located below the first gear (6), the third gear (81) and the worm (5). It can be understood that it is also possible to arrange the second transmission member (202) on top and the first transmission member (201) on the bottom; meanwhile, a second gear (7) and a fourth gear (82) are arranged above the first gear (6), the third gear (81) and the worm (5); the interface of the first transmission piece (201) and the second transmission piece (202) is still arranged downwards.
