[0041] See also Figures 1 to 5The utility model comprises an electric toothbrush for the blind, comprising a toothbrush body 1, a toothbrush cap 2 installed and connected to the left end of the toothbrush body 1, a button 3 arranged on the outer side of the toothbrush body 1, a left cap 4 arranged on the left side of the toothbrush cap 2, a right cap 5 arranged on the right side of the toothbrush cap 2, an elastic drawstring 6 fixedly connected between the left cap 4 and the right cap 5, a magnet 7 fixedly connected to the left cap 4 and the right cap 5, a toothbrush head 8 installed and connected to the left end of the toothbrush body 1, and the toothbrush body 1 and the toothbrush head 8 are movably snap-fitted into each other, a slide rail 9 fixedly connected to the inner sides of the left cap 4 and the right cap 5, and the toothbrush body 1. The outer side of the body 1 is fixedly connected with a slide groove 10, and the slide groove 10 and the slide rail 9 are slidably connected to each other. The slide groove 10 is extended near one end of the toothbrush head 8 to reserve an extra length of 3 cm, and the toothbrush body 1 and the toothbrush head 8 are installed and connected. The slide groove 10 is provided with an inclined surface at the intersection of the left end surface of the toothbrush body 1 and the extension of the slide groove 10, which can relatively separate the left cap 4 and the right cap 5. The bottom end of the toothbrush body 1 is fixedly connected with a T-shaped connecting pipe 11. The bottom end of the toothbrush body 1 is rotatably connected to two gears 12, and the gears 12 are respectively located on the left and right sides of the bottom end of the toothbrush body 1. The T-shaped connecting pipe The left and right ends of 11 are inserted into and slidably connected with T-shaped tooth plates 13, and the T-shaped tooth plates 13 are meshed with the gear 12, and the two gears 12 are meshed with a tooth plate 14. A first baffle 15 is fixedly connected to the tooth plate 14, and the first baffle 15 passes through the toothbrush body 1 and is slidably connected to the toothbrush body 1. A spring is provided at the sliding connection between the toothbrush body 1 and the first baffle 15 for automatic reset. A fixed cylinder 16 is fixedly connected to the bottom end of the toothbrush body 1, and an air inlet 17 is provided on the right end face of the fixed cylinder 16. The upper end face inside the air inlet 17 is rotatably connected to the second baffle 18, and the second baffle A torsion spring is provided at the rotational connection between 18 and the inner upper end surface of the air inlet 17 to enable the second baffle 18 to be reset in the reverse direction.

Two ventilation baffles 19 are fixedly connected to the inside of the fixed cylinder 16. A piston 20 is slidably connected to the inside of the fixed cylinder 16, and the upper end of the piston 20 passes through the fixed cylinder 16 and is inserted into the middle of the T-shaped connecting tube 11. When the piston 20 slides inside the fixed cylinder 16, it will not pass through the air inlet 17. It is slidably connected to the T-shaped connecting tube 11, and the lower end of the fixed cylinder 16 is fixedly connected to a toothpaste box 21.

[0042] The working principle of the electric toothbrush for the blind is:

[0043] First, when using, hold the toothbrush cap 2 and slide it downward, respectively driving the left cap 4 and the right cap 5 to slide on the slide groove 10 through the slide rail 9 to the two sides of the toothbrush body 1, so that the toothbrush head 8 is exposed, and then the toothbrush head 8 is removed and placed at the bottom of the toothbrush body 1;

[0044] Second, by continuing to slide the left cover cap 4 and the right cover cap 5 to move, the left cover cap 4 and the right cover cap 5 come into contact with the first baffle 15, pushing the first baffle 15 to move, driving the tooth plate 14 to drive the gear 12 to rotate, driving the T-shaped tooth plate 13 to slide inside the T-shaped connecting tube 11, and at the same time squeezing the air inside the T-shaped connecting tube 11, pushing the piston 20 to slide inside the T-shaped connecting tube 11 and synchronously slide inside the fixed cylinder 16, pushing the air inside the fixed cylinder 16 downward, and entering the toothpaste box 21 through the ventilation partition 19, pushing the toothpaste in the toothpaste box 21 to be quickly squeezed out for use;

[0045] Third, after completion, by loosening the sliding left cap 4 and the right cap 5, the second baffle 18 is pushed to reset by a spring provided at the rotation connection between the second baffle 18 and the inner side of the air inlet 17. At this time, in order to prevent the piston 20 from moving upward, the air inside the toothpaste box 21 generates negative pressure to cause the toothpaste to flow back. When the piston 20 moves, the negative pressure generated inside the fixed cylinder 16 sucks up the second baffle 18 to rotate, and the external air can enter the inner side of the fixed cylinder 16 through the air inlet 17, which can also be easily solved, and it is more convenient and simple to use.

[0046] The utility model provides an electric toothbrush for the blind through improvement. When in use, the left cover cap 4 and the right cover cap 5 are held by the hand and slid to both sides of the toothbrush body 1 so that the toothbrush head 8 is exposed and the toothbrush can be used quickly. Since the blind person's vision is obstructed, for the convenience of use, when the toothbrush head 8 is placed at the bottom of the toothbrush body 1, the toothbrush cover cap 2 is continued to slide to drive the left cover cap 4 and the right cover cap 5 to contact the first baffle 15, pushing the first baffle 15 to move and driving the T-shaped tooth plate 13 to squeeze the air, and synchronously driving the piston 20 to squeeze the air, so that the toothpaste in the toothpaste box 21 can be quickly controlled to be squeezed out. After each use, the toothbrush body 1 and the first baffle 15 are connected with each other by a spring so that they can be automatically reset. After brushing, the toothbrush cover cap 2 only needs to be slid again to cover the toothbrush head 8 again for storage.
