Detailed Description

the following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

It should be noted that the structures shown in the drawings are only used for matching with the contents disclosed in the specification, so as to be understood and read by those skilled in the art, and are not used for limiting the practical limitations of the present invention, so that the modifications or adjustments of any structure do not have the essential meaning in the art, and the technical contents disclosed in the present invention should still fall within the scope that the functions and the achievable objects of the present invention can be achieved without affecting the present invention.

As shown in fig. 1 to 3, an electric toothbrush comprises a brush head base 1 and a holding part 2, wherein the brush head base 1 is sleeved with an occlusion facing 11, a plurality of bristles 12 are arranged on the occlusion facing 11, and the brush head base 1 is of a hollow structure; the hand grip part 2 comprises a push switch 21, a motor 22, an eccentric wheel 23, a PCB24 arranged in the hand grip part 2 and a power supply 25, wherein the push switch 21, the motor 22 and the power supply 25 are all electrically connected with a PCB 24; the push switch 21 is arranged at the bottom end of the holding part 2, and the eccentric wheel 23 is arranged on an output shaft of the motor 22; the brush head base 1 is sleeved on the holding part 2, and the output shaft of the motor 22 and the eccentric wheel 23 are both positioned in the brush head base 1.

The electric toothbrush of the embodiment has the following effects:

better washing effect, time and labor saving: in the electric toothbrush of this embodiment, when in use, a user only needs to put the occlusion facing 11 into the mouth and bite the occlusion facing 11 with the teeth; at this time, the motor 22 is started to operate by pressing the push switch 21, the eccentric wheel 23 provided on the output shaft of the motor 22 rotates to vibrate the occlusion facing 11, and the bristles 12 on the occlusion facing 11 perform the functions of rubbing and brushing teeth. In the electric toothbrush of the embodiment, since the occlusion facing 11 corresponds to the shape of the oral cavity, a toothbrushing person can clean all teeth by only biting the occlusion facing 11; and the whole process does not need the swinging of the hands of the tooth brushing person, thereby saving time and labor.

Because the occlusion facing 11 adopts the soft silica gel structure, when a user brushes the teeth by using the electric toothbrush of the embodiment, the occlusion facing 11 can be twisted by rotating the holding part 2, and the bristles 21 also move up and down along with the twisting of the occlusion facing 11, so that the teeth can be brushed better.

In the electric toothbrush of the present embodiment, the grip portion 2 further includes a housing 31 and a bottom shell 32, the occlusion facing 11 is disposed at one end of the housing 31, and the bottom shell 32 is detachably connected to the other end of the housing 31; the push switch 21 is disposed on the bottom case 32, and the PCB24 and the power supply 25 are disposed in the housing 31. In the embodiment, the brush head base 1, the shell 31 and the bottom shell 32 jointly form a shell of the electric toothbrush, so that the internal electronic elements are protected; meanwhile, the bottom shell 32 is detachably connected with the shell 31, so that the internal power supply 25 is convenient to replace, and in the embodiment, the power supply 25 is preferably a button battery due to the small size of the electric toothbrush, so that the electric toothbrush is convenient to install. The motor 22 is of a detachable structure, so that the motor is convenient to maintain and replace; the lower end of the PCB24 is connected to the power supply 25 via contact pins, increasing the space utilization in the grip 2.

Specifically, the housing 31 is provided with a positioning block 33, the bottom case 32 is provided with a positioning groove 34, one side of the positioning groove 34 is provided with an opening 35 for the positioning block 33 to slide in, a projection 36 is arranged in the positioning groove 34, and the thickness of the projection 36 is not greater than the depth of the positioning groove 34. When the bottom shell 32 needs to be mounted to the housing 31, the opening 35 of the bottom shell 32 needs to be aligned with the positioning block 33, and the positioning block 33 slides into the opening 35 and enters the positioning groove 34; at this time, the bottom case 32 is twisted in a direction away from the opening 35 until the bottom case 32 is not twisted, so that the bottom case 32 and the housing 31 can be mounted, and the positioning block 33 is difficult to slide out of the positioning slot 34 due to the protrusion 36.

In the electric toothbrush of the present embodiment, the sealing ring 37 is disposed between the housing 31 and the bottom case 32, so as to increase the sealing performance between the housing 31 and the bottom case 32 and prevent water from entering the grip portion 2.

in the electric toothbrush of the embodiment, the root sections of the plurality of bristles 12 are all polygonal, and the top sections of the plurality of bristles 12 are all circular, so that the contact area between the bristles 12 and teeth can be increased to a certain extent, and the brushing effect of the toothbrush is improved. The side bristles 13 are arranged on one side of the occlusion facing 11, and the electric toothbrush of the embodiment has an occlusion structure, so that the bristles 12 are difficult to brush the side wall of the oral cavity under normal conditions; the side bristles 13 can brush the side walls of the oral cavity. The occlusion facing 11 is further provided with a flow guide hole 14, and the flow guide hole 14 can help the solution of the toothpaste flow in the oral cavity during the brushing process, so that the oral cavity brushing effect is improved.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
