Detailed Description
The invention is illustrated in fig. 1-5, where it is stated that, in order to ensure a clear illustration of the drawing, only a part of the handle outside the drive mechanism is shown, the handle outside the battery is not shown, the electric toothbrush comprises a brush head 1, a handle 2, a drive mechanism 3 and a battery 4, the brush head 1 is connected to one end of the handle 2, the drive mechanism 3 is connected between the brush head 1 and the battery 4 and is used for driving the brush head 1 to rotate;
the driving mechanism 3 comprises an electromagnet 31, a sliding block 32, a rotating seat 33, a limiting assembly 34 and two elastic sheets 35, the electromagnet 31 is fixedly connected in a brush handle 2 of the electric toothbrush and connected with a battery 4 of the electric toothbrush, the sliding block 32 is slidably connected in the brush handle 2 and has a gap with the electromagnet 31, and the rotating seat 33 is movably connected at one end of the brush handle 2 and connected with a brush head 1 of the electric toothbrush;
one end of each of the two elastic pieces 35 is fixedly connected to one side of the sliding block 32, which is opposite to the electromagnet 31, and the other end of each of the two elastic pieces 35 is fixedly connected to two sides of the center of the rotating seat 33, respectively, and an included angle between the two elastic pieces 35 is an acute angle;
a gap is reserved between the two elastic sheets 35, the limiting component 34 is a limiting shaft 342, one end of the limiting shaft 342 is fixedly connected with the rotating seat 33, the other end of the limiting shaft 342 is hinged in the brush handle 2, and the limiting shaft 342 is located in the gap and coaxially arranged with the rotating seat 33. Thereby the rotating seat can only rotate relative to the brush holder in synchronization with the limiting shaft. Therefore, when the electromagnet is electrified, the sliding block moves horizontally towards the electromagnet, the elastic sheet is stretched, and the included angle between the elastic sheet and the rotating seat and the included angle between the elastic sheet and the sliding block are gradually increased, so that the rotating seat is driven to rotate by a certain angle; when the electromagnet is powered off, the sliding block slides away from the electromagnet under the action of the self restoring force of the elastic sheet, and the rotating seat also resets in a reverse mode. When the electric toothbrush is started and the electromagnet is frequently electrified or deenergized under the influence of the control circuit, the rotating seat continuously rotates forwards or backwards.
One side of the sliding block 32, which faces away from the electromagnet 31, is fixedly connected with a fixing plate 320, one side of the rotating base 33, which faces away from the brush head 1, is provided with a boss 331, two side end faces of the boss 331 are respectively and fixedly connected with a connecting plate 330, one end of each elastic sheet 35 is connected with the fixing plate 320 into a whole, and the other end of each elastic sheet is connected with the connecting plate 330 into a whole. Therefore, 90-180 included angles are formed between the elastic sheet and the fixing sheet and between the elastic sheet and the connecting sheet, the elastic sheet has high connection stability, and meanwhile has good elastic deformation capacity and strong deformation resetting capacity through the folded angles between the elastic sheet and the fixing sheet and between the elastic sheet and the connecting sheet, and therefore the using effect of the elastic sheet is greatly improved, and the manufacturing difficulty and the installation difficulty of the elastic sheet are reduced.
The brush holder 2 is characterized in that one end of the brush holder is provided with a through hole for accommodating the rotating seat, the inner wall of the through hole is provided with at least one sealing groove, and the rotating seat 33 is externally sleeved with a sealing ring matched with the sealing groove. Thereby playing good effectual sealed, the guard action to the shell fragment to effectively prolong the holistic life of actuating mechanism.
A control switch and a control circuit are arranged between the electromagnet 31 and the battery 4. Therefore, after the electric toothbrush is started, the electromagnet is controlled to be rapidly switched between power-on and power-off.
The brush head is detachably connected to the rotary seat. Thereby enabling people to conveniently clean or replace the brush head.
The slider is a permanent magnet. Therefore, when the current directions in the electromagnets are opposite, the opposite polarities can be generated, so that the full restoring force is provided when the rotary seat is reversed, and the overall stability and reliability in use are effectively improved.
