Description
Technical Field
The present invention relates to the field of personal care appliances, and more particularly, to electric toothbrushes.
Background
Powered toothbrushes often desire to have as strong a vibration as possible while minimizing the volume and the vibration is transmitted to the brush head of the toothbrush as far as possible without being transmitted to the handle portion.
The invention discloses a structure disclosed in the invention patent with the name of 'sound wave vibration structure of electric toothbrush' in Chinese patent application No. CN 201010188777.7. In the toothbrush, the vibration source (vibration motor) is directly arranged at the front end of the transmission rod, and the toothbrush head is externally inserted in the transmission rod, so that the vibration can be transmitted only to the direction of the toothbrush head as much as possible, and finally the vibration sense on the handle is reduced.
However, in the above structure, it is difficult to control the yaw width of the transmission lever.

Fig. 2 is a sectional view taken along a-a in fig. 1.
Fig. 3 is a schematic structural view of embodiment 2.
Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 2, the novel electric toothbrush includes a handle 1, an opening is provided at one end of the handle 1, a transmission rod 2 is provided at the opening end, the transmission rod 2 includes a cavity 20, a rotating shaft 3 is fixedly provided at one end of the cavity 20, a pendulum 4 is rotatably provided on the rotating shaft 3, a first magnetic transmission wheel 5 is integrated on the pendulum 4, the novel electric toothbrush further includes a connecting shaft 6, a second magnetic transmission wheel 60 facing the first magnetic transmission wheel 5 is provided at one end of the connecting shaft 6, a third magnetic transmission wheel 61 is provided at the other end of the connecting shaft 6, a motor 7 is provided in the handle 1, a fourth magnetic transmission wheel 70 is provided on an output shaft of the motor 7, and the third magnetic transmission wheel 61 is spaced from the fourth magnetic transmission wheel 70. Through the magnetic transmission coordination among the first, second, third and fourth transmission wheels 7, the fourth magnetic transmission wheel 70 finally drives the pendulum bob 4 to rotate, and the pendulum bob 4 rotates to form the vibration of the transmission rod 2.
Furthermore, a bearing block (not shown in the figures) is inserted into the hollow space 20 of the transmission rod 2, and the connecting shaft 6 is rotatably supported by the bearing block. The handle is characterized in that a ring of annular wall 10 is arranged at the opening end of the handle 1, a stop block 21 is arranged at one end of the transmission rod 2, a notch 10a is formed in the annular wall 10, and the stop block 21 is located in the notch 10a and is in clearance fit with the notch 10 a. In the structure, when the transmission rod is manually twisted, the transmission rod cannot be twisted by an overlarge angle due to the matching of the stop block 21 and the notch 10 a; in addition, the stop 21 and the notch 10a are in clearance fit, so that the transmission rod can generate normal vibration without transmitting excessive vibration to the handle.
A first sealing part 8 and a second sealing part 9 are arranged at the lower end of the transmission rod 2 at intervals, the first sealing part 8 is arranged above the second sealing part 9, and the first sealing part 8, the second sealing part 9 and the inner side of the handle 1 are in interference fit, more specifically, the first sealing part 8 and the inner side of an annular wall 10 arranged on the handle 1 are in interference fit. The first sealing element 8 is an O-ring, and the second sealing element 9 is an inflatable sealing ring with an inflation nozzle (not shown in the figures) which can be connected with the outside. In the above structure, the transmission is stabilized on the handle by the first sealing element 8, and the deflection angle of the transmission rod 2 is controlled by controlling the gas amount in the second sealing element 9.
A bearing block (not shown in the figures) is inserted into the hollow space 20 of the transmission rod 2, and the connecting shaft 6 is rotatably supported by the bearing block. The handle is characterized in that a ring of annular wall 10 is arranged at the opening end of the handle 1, a stop block 21 is arranged at one end of the transmission rod 2, a notch 10a is formed in the annular wall 10, and the stop block 21 is located in the notch 10a and is in clearance fit with the notch 10 a. In the structure, when the transmission rod is manually twisted, the transmission rod cannot be twisted by an overlarge angle due to the matching of the stop block 21 and the notch 10 a; in addition, the stop 21 and the notch 10a are in clearance fit, so that the transmission rod can generate normal vibration without transmitting excessive vibration to the handle.
A first sealing part 8 and a second sealing part 9 are arranged at the lower end of the transmission rod 2 at intervals, the first sealing part 8 is arranged above the second sealing part 9, and the first sealing part 8, the second sealing part 9 and the inner side of the handle 1 are in interference fit, more specifically, the first sealing part 8 and the inner side of an annular wall 10 arranged on the handle 1 are in interference fit.
