In one embodiment, referring to fig. 5, the first incomplete tooth layer 32 includes a first under-tooth segment 32c, and the second incomplete tooth layer 42 includes a second under-tooth segment 42 c; the first under-toothed segment 32c and the second under-toothed segment 42c do not have teeth, and thus, when the first toothed segment 32a meshes with the incomplete output toothed segment 50a, the second under-toothed segment 42c is retracted from the output wheel 50, so that the driven wheel 30 drives the output wheel 50 to rotate in a direction opposite to the rotation direction of the driven wheel 30, without the auxiliary wheel 40 interfering with the movement of the output wheel 50; when the second toothed segment 42a meshes with the incomplete output toothed segment 50a, the first under-toothed segment 32c moves clear of the output wheel 50 so that the auxiliary wheel 40 rotates the output wheel 50 in a direction opposite to the direction of rotation of the auxiliary wheel 40 without the driven wheel 30 interfering with the movement of the output wheel 50.

In some embodiments, the first incomplete tooth layer 32 may not include the first under-tooth segment 32c, and the second incomplete tooth layer 42 may not include the second under-tooth segment 42c, as long as the auxiliary wheel 40 does not interfere with the movement of the output wheel 50 when the first toothed segment 32a is engaged with the incomplete output tooth segment 50a, and the driven wheel 30 does not interfere with the movement of the output wheel 50 when the second toothed segment 42a is engaged with the incomplete output tooth segment 50 a.

In one embodiment, the gear ratio of the first incomplete tooth layer 32 to the output wheel 50 and the gear ratio of the second incomplete tooth layer 42 to the output wheel 50 are both 1: 1, i.e. the first toothed segment 32a, the second toothed segment 42a and the incomplete output toothed segment 50a are in scalar agreement, the commutation interval (idle stroke time) of the output wheel 50 is 2 pi/3 omega, where omega is the rotational speed of the three gears.

Specifically, the first gear transmission layer 31 and the second gear transmission layer 41 have standard tooth shapes with the same parameter, so that the transmission with the constant rotating speed and the opposite rotating direction of the driven wheel 30 and the auxiliary wheel 40 is realized, and the first toothed segment 32a, the second toothed segment 42a and the incomplete output toothed segment 50a have the same parameter, so that the first toothed segment 32a and the second toothed segment 42a cooperate with the output wheel 50 to realize the motion transmission with the constant rotating speed and the periodically changed rotating direction.

In the related art, the phase angle of the output wheel in the incomplete gear reversing system depends on the outer diameter of the output wheel, the effective contact angle between the cleaning piece of the rolling brush assembly and the surface of the object to be cleaned in the handheld clothes care machine is only 120-150 degrees, if the requirement is met, the outer diameter of the output wheel needs to be increased, and the space of the rolling brush assembly is limited.

The handheld clothes care machine provided by the embodiment of the application can realize that the transmission ratio of the first incomplete tooth layer 32 to the output wheel 50 and the transmission ratio of the second incomplete tooth layer 42 to the output wheel 50 are both 1: 1 transmission, therefore, the effective contact angle of the cleaning piece and the surface of the cleaned object can reach a preset value without increasing the outer diameter of the output wheel 50, thereby saving the installation space of the shell and further leading the whole structure of the handheld clothes nursing machine to be relatively compact.

It is understood that the phase angle of the output wheel 50 can be adjusted by adjusting the outer diameters (numbers of teeth) of the first incomplete tooth layer 32, the second incomplete tooth layer 42, and the output wheel 50, and the phase angle ranges from 0 to 180 °.

It is understood that differential commutation, i.e., the difference between the normal rotation speed and the reverse rotation speed of the output wheel 50, can be achieved by adjusting the number of teeth of the first incomplete tooth layer 32 and the second incomplete tooth layer 42, the positions and the sizes of the first locking arc 32b, the second locking arc 42b and the third locking arc 50 b.

The output wheel 50 is in an idle stroke state: referring to fig. 9, the third locking arc 50b of the output wheel 50 cooperates with the second locking arc 42b of the auxiliary wheel 40 and the first locking arc 32b of the driven wheel 30 to generate locking arcs, so that the output wheel 50 is stationary at a random position within the idle stroke, where the mark point M is, for example, at the position shown in fig. 9.

Moment of engagement of driven wheel 30 with output wheel 50: referring to fig. 10, at this time, the auxiliary wheel 40 is in the non-engagement section, that is, the second under-tooth section 42c of the auxiliary wheel 40 is retracted from the output wheel 50, the first locking arc 32b of the driven wheel 30 is in the limit position engaged with the third locking arc 50b of the output wheel 50, the incomplete output tooth section 50a of the output wheel 50 and the first toothed section 32a of the driven wheel 30 are about to enter the engagement state, the output wheel 50 rotates in the direction opposite to the rotation direction of the driven wheel 30, and the mark point M is in the position shown in fig. 10 and about to rotate in the direction opposite to the rotation direction of the driven wheel 30.

It will be appreciated that after the driven wheel 30 is disengaged from the output wheel 50, the driving assembly returns to the initial state, and in cycles thereafter, the driven wheel 30 and the auxiliary wheel 40 are engaged with the output wheel 50 alternately, so that the output wheel 50 drives the roller brush assembly to rotate alternately in two opposite directions, while the driving motor 10 keeps the rotating direction unchanged.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application are included in the protection scope of the present application.
