Embodiment 1

[0042] An electric toothbrush capable of injecting foam toothpaste is mainly composed of three parts: a brush head 6, a handle 14 and a foam toothpaste adding system. The top of the brush head 6 is provided with a toothbrush part 1, the shape of the toothbrush part 1 is a cylinder, and the top end is slightly conical. The bristles around the toothbrush part 1 are wound and arranged in a helical shape. The lower end of the toothbrush part 1 is connected with a transmission rod I5 made of stainless steel. The handle 14 is provided with a transmission rod II10, one end of the transmission rod II10 is connected to the rotating motor 12 through a gear transmission, and the other end is matched with the joint I7 at the lower part of the transmission rod I5, and the junction of the joint I7 and the transmission rod II10 is a triangular prism-shaped male and female interface . One side of the toothbrush part 1 is provided with a duck tongue-shaped double-layer hollow partition 2, an...

Embodiment 2

[0044] On the basis of Embodiment 1, it also includes a reversing switch 13, a power supply chamber 15 and a charging line 16. 15 is connected, and the charging line 16 is arranged outside the power supply chamber 15, and the shape of the power supply chamber 15 and the setting position of the electrode sheet are identical with No. 1 or No. 2 dry batteries.

[0045] Reversing switch 13 comprises two rotary switches, presses any direction rotary switch, just starts automatic brushing. To change the direction of rotation, press the other rotary switch. When wanting to stop rotating, then lightly press the switch button of bouncing once, make two switch buttons all be in bouncing state toothbrush part 1 and just stop rotating.

Embodiment 3

[0047] On the basis of embodiment 2, the toothpaste injector 26 is an elastic bag, and between the outlet of the toothpaste injector 26 and the soft water pipe 18, a water filling head I24 is arranged. A one-way valve II is arranged between the outlets of the device 26. Check valve II limits foam toothpaste and can only add toothpaste injector 26 from inlet I22, and can not overflow. The toothpaste injector 26 is provided with a limit net I28 composed of silk threads to prevent the toothpaste injector 26 from expanding too large and bursting. When brushing your teeth, add a sufficient amount of foam toothpaste in the toothpaste injector 26 by the injection port 122 earlier. Then turn on the rotating motor to make the toothbrush part 1 rotate and start brushing your teeth. When brushing your teeth, you can squeeze the toothpaste injector 26 to add foam toothpaste in the oral cavity at any time as required.

[0048] Also comprise elastic water storage bag 27, be provided with ...

Abstract

The invention belongs to the technical field of daily electric appliances, and in particular relates to an electric toothbrush capable of injecting foam toothpaste. Existing electric toothbrushes and toothpastes cannot cooperate fully when used. Because the toothpaste is lumpy, it is not firmly combined with the toothbrush after being squeezed onto the toothbrush, and the toothpaste may be thrown off at the moment the electric toothbrush is started. Therefore, when using an electric toothbrush, sometimes it is necessary to re-squeeze the toothpaste, which is very inconvenient. Aiming at this, the technical scheme of the present invention is: comprise toothbrush part and rotating motor, toothbrush part is connected with rotating motor, and the side of toothbrush part is provided with the partition plate of duck tongue, and partition plate is hollow structure, and partition plate faces toothbrush part The position is provided with small holes; the hollow part of the partition is connected with a toothpaste injector through a pipeline. Also the brush head and handle are removable and replaceable. An elastic water storage bag can also be additionally set. The invention is suitable for daily tooth brushing.

Description

technical field [0001] The invention belongs to the technical field of daily electric appliances, and in particular relates to an electric toothbrush capable of injecting foam toothpaste. Background technique [0002] The electric toothbrush is a toothbrush invented by Philippe-Guy Woog. Through the rapid rotation or vibration of the motor core, the brush head generates high-frequency vibrations, instantly dispersing the toothpaste into fine foam, and deeply cleans the gap between the teeth. At the same time, the vibration of the bristles It can promote the blood circulation in the oral cavity and has a massage effect on the gum tissue. [0003] But existing electric toothbrush and toothpaste can't cooperate fully when using. Because the toothpaste is lumpy, it is not firmly combined with the toothbrush after being squeezed onto the toothbrush, and the toothpaste may be thrown off at the moment the electric toothbrush is started. Therefore, when using an electric toothbrus...
