At this time, the toothpaste chamber 12 and the transmission chamber 11 must be connected through a vertical strip opening, and a sealing strip should be provided in the strip opening to prevent toothpaste from entering the transmission chamber 11. In this case, it is directly realized that the nut 43 can move up and down but cannot rotate. Another way is that the transmission chamber 11 and the toothpaste chamber 12 are independent of each other and not communicated with each other. At this time, the pressing plate 50 and the nut 43 are magnetically connected. For example, the extrusion plate 50 is provided with an iron block, and the nut 43 is provided with a strong magnet, so that after the nut 43 moves up and down, it can also drive the extrusion plate 50 to move up and down. In this case, several rollers may be provided on the side of the pressing plate 50 .

The paste inlet chamber 62 communicates with the brush head chamber 61 through a one-way valve 63 . That is, toothpaste can only enter the brush head chamber 61 from the paste inlet chamber 62 and cannot flow back. In this embodiment, the one-way valve 63 is a rubber tube whose two ends are respectively connected to the paste inlet chamber 62 and the brush head chamber 61, and the rubber tube 63 is closed at one end of the brush head chamber 61 so as to have a sealing surface 631, which is closed. A notch 6311 is provided on the surface 631, and the notch 6311 can form a "cross"-shaped opening or a "one"-shaped opening by knife-cutting. At the same time, a rubber sleeve (not shown in the figure) can be sheathed on the outer peripheral surface of the rubber tube 63, so that under normal conditions, the cutout 6311 is in a closed state. Such a one-way valve 63 is relatively simple and easy to manufacture, and has a better effect in use.

The battery 47 is a rechargeable battery, and is connected with a slide pin 80 . For better waterproofing, the lower part of the handle shell 10 can be provided with a separate latch chamber 13 , and the sliding latch 80 can be located in the latch chamber 13 . At this time, only the connecting wires enter the transmission chamber 11 from the bolt chamber 13, which can make the waterproof effect better.

Working principle and operation method of the present invention:

1. Brush your teeth. Under normal conditions, the clutch switch 482 is not closed, and under the action of the reset compression spring 443 , the sliding tube 442 is located relatively above and is dynamically connected to the transmission rod 211 . After the user presses the brush head switch 481, the motor 46 is energized to work, the power rod 41 rotates, the sliding tube 442 drives the brush head 30 to rotate, and the teeth can be cleaned. At this time, the shield 60 can protect the walls of the oral cavity. Wherein, the speed regulation of the motor 46 and the reverse rotation of the motor 46 can be performed through the speed regulation switch 483 .

2. Squeeze out the toothpaste. Toothpaste should be added to the brush head 30 prior to brushing. Press the clutch switch 482 to close it. At this time, the coil 4411 is energized, and the sliding tube 442 is moved downward by attracting the magnet 4421 , which means that the sliding tube 442 is no longer connected to the transmission rod 211 but is powered with the screw rod 42 . The user presses the brush head switch 481 to rotate the sliding tube 442 and drive the screw 42 to rotate. Under the action of the screw nut mechanism, the nut 43 moves upwards and drives the extrusion plate 50 to move upwards. The toothpaste preloaded in the toothpaste chamber 12 passes through the paste inlet channel 22, the paste inlet chamber 62, and the one-way valve 63 to the brush head chamber 61 in sequence, and finally a certain amount of toothpaste is adhered to the brush head 30. .

3. Add toothpaste. When there is less toothpaste in the toothpaste chamber 12, the nut 43 moves up to the limit and triggers the limit switch 70 located above, and the indicator light 71 matched with the limit switch 70 lights up, and the user switches through the speed control. The switch 483 reverses the motor 46, the screw mandrel 42 reverses, the nut 43 moves downwards, and the user can open the paste inlet 121 to fill the toothpaste chamber 12 with toothpaste. In this process, once the nut 43 moves down to the limit, the limit switch 70 located below will be touched, and the indicator light 71 matched with the limit switch 70 will light up, and the user will pass the speed regulation switch 483 Motor 46 is reversed again, so that preparation is made for squeezing toothpaste next time.
