Referring to fig. 1 and 2 in combination, in the structure shown in fig. 1, when motor shaft 13 rotates in a first direction, input revolving body 30 stays at the first position, input revolving body 30 is located on top of motor shaft 13 and is in transmission coupling with output revolving body 50, at this time, power transmission is not performed between driven member 60 and output revolving body 50, and input revolving body 30 and driven member 60 are also in a state of being disengaged from each other, then in a first operating state, motor shaft 13 directly drives output revolving body 50 to rotate through input revolving body 30 and drives first output shaft 40 to rotate synchronously with motor shaft 13, at this time, first output shaft 40 outputs high rotation speed and low torque alone, and it can be understood that in the first operating state, input revolving body 30 and driven member 60 may also be in a contact coupling state. In the structure shown in fig. 2, when the motor shaft 13 runs in the direction opposite to the first direction, the input rotator 30 moves along the motor shaft 13 and stays at the second position, and when the input rotator 30 moves to the lower part of the motor shaft 13, the input rotator 30 is separated from the output rotator 50, and the input rotator 30 transmits power to the output rotator 50 through the follower 60, so that the first output shaft 40 runs at the second rotation speed, in the first operating state, when the first output shaft 40 is in the low rotation speed and high torque output state and rotates together with the second output shaft 70 to output outwards, and in the second operating state, when the first output shaft 40 outputs at a lower rotation speed and a higher torque, it can be applied to scenes such as noodles maker and noodles, and when the operation is switched between the first state and the second state, because of the difference of the rotation speed and the torque, it is particularly suitable for the situation that natural wind effect is formed by the repeated fast and slow kneading during the operation of the food material mixing, washing machine, and the electric hair dryer during the food material processing.

In order to realize the movement of the input rotator 30 on the motor shaft 13, in one embodiment, the motor assembly 1 further includes a driving member (not shown) for driving the input rotator 30 to move on the motor shaft 13, wherein the driving member has a plurality of structural forms, and in one structural form, the driving member may be an electromagnet, the electromagnet includes a first portion mounted on the input rotator 30 and a second portion mounted on the housing 20a, and under the condition of different current application, the electromagnet generates forces in different directions to realize the effect of repulsion and attraction on the input rotator 30, and drives the input rotator 30 to move between the first position and the second position on the motor shaft 13. It is understood that in the case of this structural arrangement, the cross-sectional shape of the portion of the motor shaft 13 to which the input rotor 30 is attached should be such as to limit the input rotor 30 to only move in the axial direction of the motor shaft 13, but not to allow the input rotor 30 to rotate in the circumferential direction relative to the motor shaft 13, and for this purpose, the cross-sectional shape of the portion of the motor shaft 13 to which the input rotor 30 is attached may be, for example, a D-shape, a polygonal shape, or a special-shaped structure. In another structure, the driving element may also be a lever structure mounted on the housing 20a, the lever structure has a driving end protruding out of the housing 20a and an actuating end contacting with the input rotator 30, and a user can manually press the driving end to enable the lever structure to transmit power to the actuating end in a lever principle manner to further shift the input rotator 30 to move along the motor shaft 13, of course, the power source of the driving end may also be provided by other electrical components, such as driving with other motors or driving with an air cylinder, and the like. That is, the present embodiment is conceived to drive the input rotary body 30 by applying an external force by means of a driving member as a third party driving member, and the stroke is easier to control, and it is understood that the form of the driving member of the present application is not limited to the above two forms, and a non-contact driving form in which the input rotary body 30 slides along the motor shaft 13 by blowing air flow, for example, or other feasible forms may be adopted.

In order to realize the movement of the input rotary body 30 on the motor shaft 13, in a further embodiment, referring to fig. 1 to 3 again, one of the motor shaft 13 and the input rotary body 30 is formed with a spiral groove 14 extending in the axial direction thereof, and the other is formed with a guide projection 34 fitted into the spiral groove 14, and the input rotary body 30 is driven to move in the axial direction of the motor shaft 13 by the interaction of the guide projection 34 and the spiral groove 14. In one arrangement, the spiral groove 14 is formed on the motor shaft 13, and the guide protrusion 34 is formed on the inner wall of the input rotator 30, wherein the length of the spiral groove 14 extending in the axial direction of the motor shaft 13 should be slightly greater than the distance from the first position to the second position, the guide protrusion 34 is also spiral and provided with multiple sections, during operation, when the motor shaft 13 rotates in the first direction, the input rotator 30 drives the input rotator 30 to approach the output rotator 50 and reach the first position through the driving force generated by the extrusion of the guide protrusion 34 and the wall surface of the spiral groove 14, so as to realize the transmission coupling between the input rotator 30 and the output rotator 50, and when the motor shaft 13 rotates in the direction opposite to the first direction, the guide protrusion 34 generates an opposite force to the input rotator 30, so that the input rotator 30 moves from the first position to the second position, and contacts the driven member 60 at the position and can transmit power to the output rotator 50. In the embodiment, the driving force input to the rotator 30 is achieved without using other external components, and the motor shaft 13 and the input rotator 30 are ingeniously modified in structure, so that the number of parts is reduced, the cost is reduced, and the overall structure of the motor assembly 1 is smaller and more compact.

In the embodiment of driving the input rotator 30 to move by the matching of the spiral groove 14 and the guide protrusion 34, in order to ensure the stability of the whole structure, in an embodiment, the motor shaft 13 is further provided with a first limit structure 22, and the first limit structure 22 is used for preventing the input rotator 30 from rotating out of the range of the spiral groove 14 of the motor shaft 13. In one form, the first limiting structure 22 is a snap spring installed at an end of the motor shaft 13 facing the first output shaft 40, wherein the motor shaft 13 may be provided with a snap groove to snap-fit the snap spring. Further, in order to avoid the input rotation body 30 from colliding with the housing 20a due to being rotated out of the range of the spiral groove 14 when moving on the motor shaft 13, the first limit structure 22 may further include another snap spring disposed at the joint of the motor shaft 13 located in the housing 20a and close to the housing 20a, and the snap spring may also be snap-fixed by a snap groove formed on the motor shaft 13, it is understood that the specific form of the first limit structure 22 may also be other, such as a protruding structure formed on the motor shaft 13.

In the present embodiment, in order to ensure stability during driving by the engagement of the spiral groove 14 and the guide projection 34, the groove width of the spiral groove 14 is defined as t, and the extension height of the guide projection 34 in the axial direction of the input rotator 30 is defined as h, where h is not less than 1.5t. When the extension height of the guide projection 34 in the axial direction of the input rotor 30 is too small, the support force of the guide projection in the axial direction to the input rotor 30 is too small, and thus, the phenomenon of slipping or insufficient structural strength is likely to occur, so that the stability in the operation process can be ensured by setting h to be not less than 1.5t.
