Description

Transmission and combination structure of electric toothbrush

This creation is related to the transmission combined structure, especially the transmission combined structure of an electric toothbrush.

The electric toothbrush is a convenient tool for cleaning teeth. The toothpaste foam generated by vibration can deeply clean the teeth. Conventionally, the rotating shaft of the motor is connected through the transmission shaft to transmit the rotational movement of the motor, which is used as the vibration source of the electric toothbrush. However, the conventional electric toothbrush does not have a good connection between the transmission structure and the motor shaft. Therefore, how to solve the above problems is the direction that researchers in this field should strive for.

One of the purposes of this creation is to provide a better combination of transmission structure and effects. In order to achieve the above-mentioned purpose, the present invention provides a transmission combination structure of an electric toothbrush, which includes: a transmission shaft with a first sleeve at one end, the first sleeve with a first joint; and a motor with a The rotating shaft is provided with a second shaft sleeve, the second shaft sleeve has a second joint portion, and the first and second joint portions have corresponding cross-sectional shapes for corresponding joints. With this design, a better transmission combined structure and effect can be achieved.

The above-mentioned purpose of this creation and its structural and functional characteristics will be described based on the preferred embodiments of the accompanying drawings. Please refer to Figures 1 to 2, which are a three-dimensional exploded view and a three-dimensional combined view of an embodiment of the transmission and combination structure of the electric toothbrush in this creation. As shown in the figure, the transmission and combination structure of the electric toothbrush in this creation includes a transmission Shaft 10 and a motor 30. One end of the transmission shaft 10 has a first sleeve 11, the first sleeve 11 has a first joint 12, and the first joint 12 is shown as being recessed on the first sleeve 11. The motor 30 has a rotating shaft 31, the rotating shaft 31 is provided with a second sleeve 32, the second sleeve 32 has a second joint 33, and the second joint 33 is shown as protruding from the second shaft The sleeve 32, and the first and second joint portions 12, 33 have corresponding cross-sectional shapes and are correspondingly joined. When the motor 3 rotates, the rotational movement of the motor 3 can be transmitted. The first joint 12 has a cross section and the second joint 33 has a cross section corresponding to the first joint 12. In addition, the first joint portion 12 can also be selected to have a straight cross section (as shown in Figure 3a), a m-shaped cross section (as shown in Figure 4a), and a gear-shaped cross section (as shown in Figure 5a). ), a large-shaped cross-section (as shown in Figure 6a), a polygonal cross-section (as shown in Figures 7a and 8a), or any geometric cross-section, and the second joint 33 corresponds to the first joint 12 also has a straight cross section (as shown in figure 3b), a m-shaped cross section (as shown in figure 4b), a gear-shaped cross section (as shown in figure 5b), and a large-shaped cross section (as shown in figure 6b). As shown in the figure), a polygonal section (as shown in Figures 7b and 8b) any or any geometrical shape section. And the first and second joint parts 12, 33 can be fixed by any one of bonding, clamping, tight fitting and welding. In an alternative embodiment, the first engaging portion 12 is shown as being convexly provided on the first sleeve 11, and the second engaging portion 33 is shown as being concavely provided on the second sleeve 32. With this design, the first and second joints of the corresponding cross-sectional shape are correspondingly jointed, so that the rotation movement of the motor can be transmitted, which has a better transmission and combination structure and effect. This creation has been described in detail above, but what is described above is only a preferred embodiment of this creation, and should not limit the scope of implementation of this creation. That is to say, all equal changes and modifications made in accordance with the scope of the application for this creation shall still fall within the scope of the patent for this creation.
