Detailed Description
To facilitate an understanding of the invention, the invention is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Fig. 1 is the utility model discloses an explosion diagram of electric toothbrush embodiment of first mechanism of swing brush, fig. 2 is the utility model discloses a structural cross section schematic diagram of electric toothbrush embodiment of first mechanism of swing brush, see fig. 1 and fig. 2 in this embodiment, including casing 7, the inside motor 9 that is equipped with of casing, be equipped with an output shaft on the motor 9, eccentric shaft 8 has been cup jointed on the output shaft, eccentric shaft 8 is connected to 3 one end of connecting rod, connecting rod 3 fixes the inboard at support 6 through location axle 4 and shell fragment 5, the first 1 of brush is connected to the 3 other ends of connecting rod, connecting rod 3 with the junction of the first 1 of brush is equipped with a sealing washer 2. In the assembling process, firstly, the connecting rod 3 is assembled and fixed in the bracket 6 through the positioning shaft 4 and the elastic sheet 5; then, assembling the eccentric shaft 8 on an output shaft of the motor 9, then assembling the motor 9 in the bracket 6, and clamping the eccentric shaft 8 in a clamping groove at the bottom of the connecting rod 3; next, assembling the seal ring 2 on the corresponding position of the connecting rod 3 to form a core assembly; then the core subassembly assembled by the steps is assembled into the handle 7; finally, the brush head 1 is assembled on the connecting rod 3.
Referring to fig. 3-5, for the structure schematic diagram of the electric toothbrush head left-right swing and final reset of the brush head mechanism of the present invention, when the eccentric shaft is deviated to the right, the connecting rod bottom is driven to the right, the connecting point of the connecting rod and the brush head is moved to the left, the left side of the brush head bottom extrudes the gap between the brush head and the bracket, so that the brush head is moved to the left, as shown in fig. 3. When the eccentric shaft deflects leftwards, the bottom of the connecting rod is driven leftwards, the joint of the end of the connecting rod and the brush head moves rightwards, and the left side of the bottom of the brush head extrudes a gap between the brush head and the bracket, so that the brush head moves rightwards, as shown in fig. 5. When the motor stops rotating, the eccentric shaft and the connecting rod return the brush head to the central position under the action of the elastic sheet on the bracket.
The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
