As shown in fig. 1-2, as an embodiment of the present invention, an electric toothbrush is disclosed, which comprises a brush holder 1 and a brush head 2, wherein the brush head 2 comprises a bristle portion 21, and a driving mechanism for driving the bristle portion 21 to move is provided in the brush holder 1. In the embodiment, the driving mechanism comprises a vibration motor 11 and a storage battery 12 connected below the vibration motor 11, the storage battery 12 is used for providing power for the vibration motor 11, the vibration motor 11 is used for providing power for the bristle part 21 to reciprocate in the direction perpendicular to the brush head 2, in other embodiments, the vibration motor 11 can also be selected from a rotary motor so as to provide power for the bristle part 21 to rotate clockwise or counterclockwise, and the effect of electric tooth brushing is also achieved. A water outlet channel 22 is arranged in the brush head 2, and a water storage tank 13 and a water pumping mechanism for connecting the water storage tank 13 and the water outlet channel 22 are also arranged in the brush handle 1. In this embodiment, the water pumping mechanism includes a water pump 14 and a motor 15 disposed below the water pump 14, the water pump 14 is configured to convert water flowing therein into a high-pressure fine water flow and output the high-pressure fine water flow, and the motor 15 is configured to drive the water pump 14 to operate. The toothbrush in the embodiment has the function of electric tooth brushing, can efficiently complete tooth brushing action, and reduces the difficulty in mastering tooth brushing angles and force in the tooth cleaning process compared with manual tooth brushing, thereby being convenient to use. Meanwhile, the vibration of the brush part 21 can enable the mixture of toothpaste and water in the oral cavity to generate a large number of micro bubbles, and the pressure generated when the bubbles burst can clean and soften dirt and bacteria in the slit between the teeth and the gingival sulcus for the first time. In addition, the water in the water storage tank 13 can be sprayed out from the brush head 2 in the form of high-pressure fine water flow by the water pump 14 to clean teeth, and because a large amount of mixture of toothpaste and water is adhered to the positions of cleaning dead angles such as slits between teeth, gingival sulcus and the like in the process of electric tooth brushing and dirt and bacteria at the positions are cleaned and softened for the first time, when the high-pressure fine water flow is sprayed to the positions, the residual dirt and bacteria are easily washed again, so that the effect of thorough cleaning is achieved by a double cleaning mode of electric tooth brushing and tooth rinsing. And compare the mode that directly switches on the water source and wash among the prior art, because the utility model provides a high-pressure thin rivers impact force is bigger, therefore has the better washing effect of effect. And because the water storage tank is arranged in the brush handle of the utility model, the toothbrush is not limited by the water inlet hose, the toothbrush can be moved at will when in use, and the use is more convenient.

In other embodiments, the brush head 2 further comprises a brush head neck 23, and the water outlet channel 22 is arranged in the brush head neck 23, however, in other embodiments, the water outlet channel 22 can also be arranged outside the brush head neck 23, and all have the function of water flow transmission. The upper end of the neck portion 23 of the brush head is provided with a mounting base 24 for mounting the bristle portion 21, in this embodiment, the mounting base 24 is fixedly connected with the bristle portion 21, of course, in other embodiments, the mounting base 24 and the bristle portion 21 may be movably connected by a screw structure, so as to facilitate the replacement of the bristle portion 21 alone.

In other embodiments, the brush head 2 is detachably connected to the brush handle 1 to facilitate replacement of the brush head 2, thereby extending the life of the brush handle 1, or to enable multiple users to use one brush handle 1, thereby saving resources and money. This embodiment should dismantle connected mode chooses for use to carry out the buckle through setting up the draw-in groove and setting up the fastener on 1 top of brush holder at brush head neck 23 bottom and connect, of course, should dismantle connected mode also can choose for use to carry out threaded connection through setting up helicitic texture at brush head neck 23 bottom and 1 top of brush holder in other embodiments, also has same effect.

In other embodiments, the upper end of the brush handle 1 is provided with a first water outlet structure 143, the lower end of the neck 23 of the brush head is provided with a first water inlet structure 221 communicated with the water outlet channel 22, and the first water outlet structure 143 can be butted with the first water inlet structure 221, so as to realize the circulation of water between the brush handle 1 and the brush head 2. The first water outlet structure 143 is connected to the water outlet end 142 of the water pump 14 through a water pipe, and the water storage tank 13 is connected to the water inlet end 141 of the water pump 14 through a water pipe, so that the water in the water storage tank 13 is pumped into the water pump 14, is subjected to high pressure treatment, and is delivered into the water outlet channel 22 through the first water outlet structure 143 and the first water inlet structure 221. The upper end part of the brush head neck part 23 is provided with a second water outlet structure 222 communicated with the water outlet channel 22, and high-pressure water in the water outlet channel 22 is sprayed to the outside in the form of high-pressure fine water flow through the second water outlet structure 222, so that dirt and bacteria still remained in the slit between teeth, particularly in the gingival sulcus after primary cleaning and softening are washed, and the purpose of thorough cleaning is achieved.

In other embodiments, as shown in fig. 3, the second water outlet structure 222 is disposed on the mounting base 24, and the bottom of the bristle part 21 is provided with a water spraying part 211 for communicating with the second water outlet structure 222.
