DETAILED DESCRIPTION

[0024] See Figure 1-Figure 5As shown, the technical solution adopted in this specific embodiment is: it includes a fuselage 1, a brace 2, the brace 2 is detachably connected to the fuselage 1, a reciprocating vibration mechanism 3 and a power mechanism 4 are provided in the fuselage 1, the bottom of the reciprocating vibration mechanism 3 is connected to the power mechanism 4, and the top of the reciprocating vibration mechanism 3 is connected to the brace 2, the reciprocating vibration mechanism 3 includes a moving single cylinder 5, a silicone sealing sleeve 7, a wire cylinder 8, a screw 9, a bevel gear transmission shaft 10, a transmission shaft 11, a bevel driven gear 12, and an eccentric wheel 14. There are two groups of the above structures and they are symmetrically arranged in the fuselage 1, the screw 9 is arranged in the wire cylinder 8 and connected to the wire cylinder 8 Threaded connection, the wire drum 8 is arranged in the mobile monocylinder 5 and is sealed with the silicone sealing sleeve 7, the silicone sealing sleeve 7 is sealed with the braces 2, the end of the screw rod 9 is connected to the bevel gear transmission shaft 10, the bevel driven gear 12 is connected to one end of the transmission shaft 11, the eccentric wheel 14 is arranged on the bevel driven gear 12, and the eccentric wheel 14 is movably connected to the end of the mobile monocylinder 5, the transmission shaft 11 is transmission-connected to the power mechanism 4, the mobile monocylinder 5 is provided with a first limit movement groove 5-4, the end of the wire drum 8 is provided with a wire drum flat position 8-1, and the wire drum flat position 8-1 matches the first limit movement groove 5-4. The soft braces 2 provide better protection for teeth, and the comprehensive cleaning method provides better cleaning effect. The reciprocating vibration mechanism 3 includes two sets of symmetrically arranged mobile monocylinders 5, silicone sealing sleeves 7, wire cylinders 8, screw rods 9, bevel gear transmission shafts 10, transmission shafts 11, bevel driven gears 12, and eccentric wheels 14. The eccentric wheels 14 are movably connected to the end of the mobile monocylinder 5. When the power mechanism 4 drives the eccentric wheel 14 to rotate, the mobile monocylinder 5 is driven to move rapidly, thereby generating high-frequency vibrations. The high-frequency vibrations are transmitted to the braces 2, so that the braces 2 can move smoothly when brushing teeth. High-frequency vibration is used to clean the dirt on the tooth surface and between the teeth. During the rotation of the screw rod 9, since the end of the wire drum 8 is provided with a wire drum flat position 8-1, the wire drum flat position 8-1 matches the first limit movement groove 5-4, the wire drum 8 does not rotate, but produces a linear motion, thereby realizing the left and right movement of the braces 2. At the same time, the screw rod 9 drives the wire drum 8 to move relatively slowly, and the high-frequency vibration is combined with the low-frequency motion during the brushing process, so that the bristles move back and forth on each tooth to clean, realizing fully automatic brushing.

[0025] Furthermore, the mobile monocular 5 comprises a cylinder 5-1 and a base 5-2. The cylinder 5-1 is made of aluminum alloy, and the base 5-2 is made of plastic. The cylinder 5-1 and the base 5-2 are integrally formed. A rotation groove 5-3 is provided at the end of the base 5-2, and the rotation groove 5-3 matches the eccentric wheel 14. The integrated structure has higher strength, and the combination of aluminum alloy and plastic makes the overall weight smaller, which is convenient for longer-term use, does not bring additional burden to the user, and provides a better user experience.

[0026] Furthermore, a driven gear 13 is provided at one end of the transmission shaft 11. The power mechanism 4 includes a motor 15 and a drive worm 16. One end of the drive worm 16 is connected to the motor 15, and the body of the drive worm 16 meshes with the driven gear 13. The drive worm 16 simultaneously drives the two driven gears 13, driving the reciprocating vibration mechanism 3 to operate. When the drive worm 16 rotates, the two driven gears 13 rotate in opposite directions, thereby driving the two screws 9 to rotate in opposite directions, achieving opposite displacement of the two wire drums 8, and driving the braces 2 to move in two directions for automatic brushing.

[0027] Furthermore, the dental brace 2 includes bristles 2-1 and a dental brace body 2-2. The bristles 2-1 are detachably connected to the dental brace body 2-2, and the dental brace body 2-2 is made of silicone. The detachable connection between the bristles 2-1 and the dental brace body 2-2 allows individual bristles 2-1 to be removed and replaced with new ones when they become worn, without having to replace the entire dental brace 2. This reduces the cost of use, and the silicone dental brace body 2-2 provides a better user experience.

[0028] Furthermore, the fuselage 1 includes an upper cover 1-1 and a lower cover 1-2, and the reciprocating vibration mechanism 3 is provided with a double-cylinder fixed cover 6, a lower fixed cover 19, and an upper fixed cover 20. The double-cylinder fixed cover 6 is arranged in the upper cover 1-1 and corresponds to the position of the cylinder 5-1. The double-cylinder fixed cover 6 fixes the reciprocating vibration mechanism 3 on the lower cover 1-2, and the fixed cover 19 is arranged in the lower cover 1-2 and corresponds to the position of the base 5-2. The double-cylinder fixed cover 6 is provided with a second limit movement groove 6-1, and the position of the second limit movement groove 6-1 corresponds to the first limit movement groove 5-4. The double-tube fixed cover 6 is used to fix the reciprocating vibration mechanism 3 and position the travel of the wire tube 8. The fixed cover 19 corresponds to the position of the base body 5-2 and is used to position and fix the base body 5-2. One end of the eccentric wheel 14 is movably connected to the fixed cover 19 to ensure the stability of the eccentric wheel 14 during rotation. The multiple fixed covers firmly fix the vibration device, making the vibration transmission better and the cleaning effect better.

[0029] Furthermore, the body 1 is provided with a battery 17, a main control board 18, and a wireless charging induction coil 21. The battery 17 is provided on one side of the power mechanism 4, the main control board 18 is provided on the double-barrel fixed cover 6, and the wireless charging induction coil 21 is provided at the bottom of the body 1. The battery 17 is electrically connected to the power mechanism 4, the main control board 18, and the wireless charging induction coil 21. The bottom of the body 1 is provided with a wireless charging base 3, which is provided with a wireless charging transmitting coil 3-1 and a wireless charging control board 3-2. The main control board 18 controls the travel of the reciprocating vibration mechanism 3. When the wireless charging induction coil 21 and the wireless charging transmitting coil 3-1 are close to each other, a charging signal is triggered to charge the device. Wireless charging is more convenient and faster, providing people with a better user experience.

[0030] The working principle of the present invention is as follows: two sets of reciprocating vibration structures are provided in the reciprocating vibration mechanism 3, which are movably connected to the braces 2 from both sides, so that the reciprocating vibration mechanism 3 can drive both sides of the braces 2 when working. When the power mechanism is started, the driving worm 16 drives the driven gears 13 on both sides to rotate, thereby driving the conical driven gear 12 and the eccentric wheel 14 to rotate. During the rotation process, the eccentric wheel 14 drives the seat body 5-2 to move at high frequency, realizing the high-frequency vibration of the mobile monotube 5. The high-frequency vibration of the mobile monotube 5 is transmitted to the wire drum 8 and then to the braces 2, realizing the high-frequency vibration of the braces 2; the conical driven gear 12 will drive the conical gear transmission shaft 10 when rotating. Rotation, the bevel gear transmission shaft 10 drives the screw rod 9 to rotate. During the rotation of the screw rod 9, since the end of the wire drum 8 is provided with a wire drum flat position 8-1, the wire drum flat position 8-1 matches the first limit movement groove 5-4, the wire drum 8 does not rotate, but produces a linear motion. Since the two driven gears 13 rotate in opposite directions when the driving worm 16 rotates, the movement directions of the two wire drums 8 are different, thereby realizing the movement of the braces 2 on the left and the right. At the same time, the movement of the wire drum 8 by the screw rod 9 is relatively slow, and the combination of high-frequency vibration and low-frequency motion is realized during the brushing process, so that the bristles move back and forth on each tooth to clean, realizing fully automatic brushing.

[0031] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
