[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Embodiment 1
[0025] Refer to the attached Figure 1-5The utility model proposes a new type of electric toothbrush, including a handle 11, on which a brush head 121 is installed, an installation chamber is arranged inside the brush head 121, the inner wall of the installation chamber is rotatably connected to a bristle wheel 34 through a rotating shaft (part of the volume of the bristle wheel 34 is outside the brush head 121), and a driving mechanism is arranged inside the installation chamber, which is used to drive the bristle wheel 34 to rotate; wherein the bristle wheel 34 is cylindrical, and the bristle material on the bristle wheel 34 is the same as the bristle material on the existing toothbrush.
[0026] A power source (not shown in the power diagram) is also disposed inside the handle 11 , and the power source is used to supply power to the driving motor 31 .
[0027] A brush head mounting handle 122 is fixedly installed on the bottom wall of the brush head 121, and the brush head mounting handle 122 can be detachably mounted on the handle 11. Two slots 22 are provided on the top wall of the handle 11, and two plug rods 21 are fixedly installed on the end wall of the brush head mounting handle 122 away from the brush head 121, and the plug rods 21 are plugged and fixed inside the slots 22; wherein, the brush head 121 can be replaced, and when replacing, the plug rod 21 can be pulled out from the slot 22, thereby realizing the disassembly of the brush head mounting handle 122, and then the brush head 121 can be replaced; it should also be noted that: the plug rod 21 and the slot 22 are connected in an interference fit, that is, the plug rod 21 will not be easily removed from the slot 22 without applying external force to pull the plug rod 21.
[0028] A rotating sealing ring 123 is installed at the top of the inner wall of the brush head 121, and the outer wall of the worm 33 is installed on the inner wall of the rotating sealing ring 123; wherein, a rotating sealing ring 123 is installed at the top position of the inner wall of the brush head 121, so that the worm 33 and the inner wall of the brush head 121 are in a sealed rotational connection, thereby preventing water from flowing into the interior of the brush head 121.
[0029] The driving mechanism includes a driving motor 31 fixedly mounted inside the handle 11, a connecting rod 32 is fixedly mounted on the end wall of the output shaft of the driving motor 31, a worm 33 is rotatably connected to the inner wall of the brush head 121, a connecting hole 331 is opened on the end wall of the worm 33, and the connecting rod 32 is plugged and fixed inside the connecting hole 331; wherein, the bottom end of the worm 33 is arranged at a position close to the bottom opening of the brush head mounting handle 122, so that it is convenient to plug the connecting rod 32 into the connecting hole 331. It should also be noted that the shape of the connecting rod 32 and the connecting hole 331 are both "D" shaped, so that when the connecting rod 32 rotates, the worm 33 can be driven to rotate.
[0030] An annular mounting groove is provided in the middle of the outer wall of the bristle wheel 34, in which a worm wheel 35 is fixedly installed, and the worm wheel 35 meshes with the worm 33; wherein the outer diameter of the worm wheel 35 is smaller than the outer diameter of the bristle wheel 34, that is, during brushing, the worm wheel 35 will not contact the teeth.
[0031] A tooth groove 124 is formed on the side wall of the brush head 121 , wherein teeth can enter into the tooth groove 124 , thereby increasing the range of teeth cleaning by the bristle wheel 34 , and the shape of the inner wall of the tooth groove 124 can be designed to be arc-shaped, so as to facilitate the entry of teeth.
[0032] There are two bristle wheels 34 (the two bristle wheels 34 are respectively located on the inner and outer sides of the teeth), and the two bristle wheels 34 are respectively located on both sides of the tooth groove 124. Two groups of spiral teeth in opposite directions are provided on the outer wall of the worm 33, and the two worm wheels 35 are respectively engaged with the two groups of spiral teeth; wherein, when the worm 33 rotates, the two worm wheels 35 rotate in opposite directions.
[0033] A plurality of through holes 125 are provided on the outer wall of the brush head 121; wherein, the through holes 125 are provided on the side wall and the bottom wall of the brush head 121, and the through holes 125 on the side wall facilitate the outside air to enter the interior of the brush head 121, which can help to accelerate the drying of the bristles on the brush wheel 34, and the through holes 125 located on the bottom wall of the brush head 121 can facilitate the discharge of accumulated water inside the brush head 121.
