[0002] Electric toothbrushes are loved by many users because they generate their own power, are easy to use, save effort, and have good cleaning power. The existing electric toothbrushes mainly include a handheld shell and a toothbrush head connected to the front end of the handheld shell in terms of structural design. The handheld shell has a built-in vibrator, which is connected to the toothbrush head through a power output shaft on the vibrator. The toothbrush head mainly includes a connecting rod and a brush part arranged at the front end of the connecting rod. The connecting rod is connected to the power output shaft of the vibrator. The connecting rod plays a transition role to increase the swing amplitude of the front end. By vibrating the connecting rod, a larger vibration can be generated on the brush part to achieve an electric brushing operation.

[0003] When brushing teeth, some deep dirt remaining in the teeth needs to be brushed from multiple directions to be removed.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-4 In an embodiment of the utility model, an electric toothbrush with multi-frequency integrated in a toothbrush head based on a thin film circuit comprises a handheld housing 10, a vibration rod 20 installed at the front end of the handheld housing 10, and a brush head 30 installed at the front end of the vibration rod 20. A power supply unit 40, an electric control unit 50 and a first vibrator 60 are integrated in the handheld housing 10. The vibration rod 20 has a hollow structure that seals and separates the brush head 30. A thin film circuit (not shown), a second vibrator 70 and a third vibrator 80 are integrated in the vibration rod 20. A vibrator extending into the handheld housing 10 is provided at the front end of the handheld housing 10. A connecting pipe fitting 90 inside the shell 10, the first vibrator 60 acts on the connecting pipe fitting 90, the vibration rod 20 is sealed and connected to the connecting pipe fitting 90, the thin film circuit extends into the inside of the handheld shell 10 along the connecting pipe fitting 90, the second vibrator 70 is arranged in the middle part of the vibration rod 20, the third vibrator 80 is arranged at the front end of the vibration rod 20, and the third vibrator 80 is connected to the brush head 30, wherein the first vibrator 60 is electrically connected to the electric control unit 50, the second vibrator 70 and the third vibrator 80 are both electrically connected to the electric control unit 50 through the thin film circuit, and the electric control unit 50 is electrically connected to the power supply unit 40.

[0028] In the above technical solution, the electric toothbrush is configured to consist of three parts: a handheld shell 10, a vibration rod 20 and a brush head 30. By integrating three vibrators on the electric toothbrush, the start and stop of the three vibrators are controlled in different ways, that is, the three vibrators can be independently regulated, thereby achieving three-frequency and three-amplitude vibration regulation, which can promote the cleaning of some deep-seated dirt in the teeth, improve the cleaning effect of the brush on the teeth, and achieve the best cleaning effect.

[0029] The first vibrator 60 is a vibrator of a traditional electric toothbrush, which is arranged inside the handheld body. The second vibrator 70 is arranged in the vibration rod 20 and can generate vertical vibration. It is arranged in the front part integrated inside the vibration rod 20; the third vibrator 80 is arranged at the front end of the vibration rod 20, and it directly acts on the brush head 30, and can generate horizontal vibration.

[0030] By using a thin film circuit to integrate into the interior of the vibration rod 20, it is thinner than using a wire, so that the vibration rod 20 itself can power the second vibrator 70 and the third vibrator 80 under structural limitations, thereby achieving a highly compact structural setting. In addition, by cooperating with the connecting pipe 90, a sealed connection is achieved between the handheld shell 10 and the vibration rod 20, so that the first vibrator 60, the second vibrator 70 and the third vibrator 80 can all be waterproof, so that the internal circuit of the electric toothbrush does not wade through water, thereby ensuring the long-term normal use of the electric toothbrush.

[0031] See also Figure 3-4 A fixing frame 11 is provided inside the handheld shell 10, and the power supply unit 40, the electric control unit 50 and the first vibrator 60 are all fixedly installed on the fixing frame 11, and the connecting pipe 90 is sealed and docked with the front end of the handheld shell 10, and one end of the connecting pipe 90 extends into the handheld shell 10 and docks with the fixing frame 11; specifically, a transition beam 12 is formed at the front end of the fixing frame 11, and a fixed end 13 is formed at the front end of the transition beam 12. The connecting pipe 90 is inserted at the front end of the fixed end 13, and a vibration shell 14 is formed at the rear end of the fixed end 13, and the first vibrator 60 is installed in the vibration shell 14; when the handheld shell 10 is tightly grasped, the front end of the fixing frame 11 is provided with the transition beam 12, and the vibration generated by the first vibrator 60 can reduce the vibration amplitude due to the transition of the transition beam 12, so that the vibration effect generated by the first vibrator 60 can be concentrated on the connecting pipe 90, thereby improving the vibration efficiency.

[0032] See also Figure 3-4 A sealing sleeve 91 is provided on the outside of the connecting pipe 90, and the connecting pipe 90 is sealed and docked with the handheld shell 10 through the sealing sleeve 91. The sealing sleeve 91 can seal and deform to prevent the handheld shell 10 from wading. At the same time, it can buffer the connecting pipe 90 by deformation when vibration occurs, thereby reducing the hindering force of the front end of the handheld shell 10 on the vibration of the connecting pipe 90.

[0033] See also Figure 1-3The portion of the connecting pipe 90 exposed from the front end of the handheld shell 10 has a tapered end 92 and a straight end 93 formed in front of the tapered end 92, and a positioning portion 94 is also formed on the straight end 93 and the tapered end 92. The vibration rod 20 is sealed and plugged with the straight end 93, and the rotation of the vibration rod 20 is limited by the positioning portion 94. The vibration rod 20 is matched with the front end clearance of the handheld shell 10 through the tapered end 92; through this arrangement, the cooperation between the vibration rod 20 and the handheld shell 10 is made more compact, and the firm stability of the connection between the vibration rod 20 and the connecting pipe 90 is ensured. Since the vibration rod 20 is integrated with a circuit, in terms of setting, after the vibration rod 20 is fixed, the vibration rod 20 and the connecting pipe 90 can be fixed by bonding, and the brush head 30 can be provided with a disassembly structure, which can be replaced by replacing the brush head 30.

[0034] See also Figure 3-4 A plurality of snap-in strips 21 surrounding the second vibrator 70 are evenly arranged inside the vibration rod 20, and a gap for inserting a thin film circuit is formed between the second vibrator 70 and the inner wall of the vibration rod 20 through the snap-in strips 21, so that the thin film circuit is electrically connected to the third vibrator 80 after passing through the second vibrator 70; the first vibrator 60 and the second vibrator 70 both include a motor 61 and an eccentric wheel 62 connected to the motor 61 by power, and the first vibrator 60 and the second vibrator 70 are fixed by the motor 61, and the third vibrator 80 is a sheet structure, generally set as an ultrasonic vibration sheet. Considering that the space at the position where the vibration rod 20 is connected to the brush head 30 is small, it is more reasonable to use a sheet structure design.
