Description

Technical Field

[0001] The invention relates to the technical field of toothbrushes, in particular to an electric toothbrush. Background Art

[0002] Electric toothbrushes are the most commonly used tooth cleaning appliances. They are used to remove bacteria, plaque and small debris attached to the teeth. They can prevent periodontal diseases and protect people's oral hygiene and dental health. There are many kinds of electric toothbrushes on the market now, with different structures, but there are some problems. The existing electric toothbrush handles have only one layer, and the signal indicator light is directly emitted from the handle. The structure is simple, the shape is monotonous, and the toothbrush handle is easy to wear; there is no buffer pad between the existing electric toothbrush motor and the drive shaft and the toothbrush handle. The drive shaft will generate a lot of noise during the high-frequency swing process, which will cause adverse effects on the user's body and mind.

[0003] If you want to spray paint on the handle of a traditional electric toothbrush, you need to spray the paint on the inner wall of the handle, which is very difficult to construct and has high production costs. The light transmitted from the LED in the inner cavity of the handle is dim and the light transmission effect is poor.

[0039] A brush head 3 is connected to the upper end 11 of the brush handle 1, and a plurality of bristles 31 are provided on the brush head 3;

[0040] The light emitting element 4 is disposed in the internal chamber 10 and is configured so that the light emitted from the light emitting element 4 can be seen through the light-transmitting portion on the side wall of the brush handle and the cover 2;

[0041] A power source 5 is disposed in the internal chamber 10 and supplies power to the light emitting element 4;

[0042] a motor 6 , within the internal chamber 10 , powered by the power source 5 ;

[0043] a drive shaft 7, driven by the motor 6, configured to impart motion to at least one of the brush heads 3, so that the brush head 3 drives the bristles 31 to move;

[0044] A printed circuit board 8 is disposed in the internal chamber 10, powered by the power supply 5, and configured to drive the motor 6 to operate;

[0045] The button 9 is arranged on the brush handle 1. The button 9 is configured to be pushed when force is applied to a part of the side wall of the brush handle, thereby triggering the printed circuit board 8 to work, thereby driving the motor 6 to operate and driving the light-emitting element 4 to emit light.

[0046] The present invention provides an electric toothbrush, which is provided with a cover on the handle, so that the light emitted from the signal indicator light is reflected and refracted multiple times between the outer wall of the handle and the cover, forming a good light and shadow effect, making the toothbrush handle more three-dimensional and shortening the distance between the electric toothbrush and the user. The present invention provides an electric toothbrush, which can spray paint on the outer wall of the toothbrush handle, and then use a laser to sweep away part of the paint on the outer wall of the toothbrush handle to open a light-transmitting window, so that the light transmitted by the LED lamp in the inner cavity of the toothbrush handle is brighter and the light-transmitting effect is better, which greatly reduces the construction difficulty of paint spraying and the production cost of the toothbrush handle.
