Description

Technical Field

[0001] The utility model relates to the technical field of toothbrush manufacturing, in particular to an integrally washable electric toothbrush. Background Art

[0002] Oral health is an item that has been increasingly emphasized in modern medicine. Most people's oral health problems are related to the degree of tooth cleaning. Therefore, most dentists recommend using the Bass brushing method to clean teeth. However, the Bass brushing method is relatively difficult. Therefore, most people will choose an electric toothbrush to simulate the Bass brushing method to clean teeth. Generally, an electric toothbrush is divided into two parts: a charging stand and a toothbrush body.

[0003] Generally, when using an electric toothbrush to brush teeth, the toothpaste foam in the user's mouth may flow into the gaps inside the electric toothbrush. After the toothpaste foam dries, it will form relatively hard toothpaste fragments sticking inside the gaps. Therefore, when the user generally conducts a comprehensive cleaning of the electric toothbrush, the user needs to rinse it with water.

[0004] Generally, the bottom of the electric toothbrush is connected to the base for charging. Therefore, when washing with water, the user needs to keep the electric toothbrush in an upward position to prevent water from flowing into the interior of the toothbrush body along the connection port. In view of the above situation, we propose an integrally washable electric toothbrush. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and an integrally washable electric toothbrush is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An integrally washable electric toothbrush includes a toothbrush body and a brush handle movably inserted above the toothbrush body. The top of the brush handle is fixedly connected with a toothbrush head. The bottom of the toothbrush body is provided with a base for positioning the toothbrush body. The bottom of the toothbrush body is provided with a washable mechanism for preventing water from entering the interior of the toothbrush body. The washable mechanism includes:

[0008] An electric connecting rod movably connected inside the toothbrush body for electrically connecting the base and the toothbrush body;

[0009] A spring, the bottom of which is fixedly connected inside the toothbrush body for adjusting the position of the electric connecting rod;

[0010] A sealing ring is fixedly connected to the outer surface of the electric connecting rod. The top of the sealing ring is fixedly connected with a positioning plate, and the inner wall of the positioning plate is fixedly connected to the outer surface of the electric connecting rod.

[0011] Preferably, the top of the spring is fixedly connected to the bottom of the positioning plate, and the positioning plate is slidably connected to the inside of the toothbrush body.

[0012] Preferably, a magnetic attraction block is fixedly connected to the top of the electrical connecting rod, a connecting conductor is arranged above the magnetic attraction block, the bottom of the connecting conductor is fixedly connected to the inner wall of the toothbrush body, and a switch is arranged on the outer surface of the toothbrush body.

[0013] Preferably, a card slot is arranged at the bottom of the toothbrush body, a snap ring is movably clamped inside the card slot, and the bottom of the snap ring is fixedly connected to the inner wall of the base.

[0014] Preferably, a bottom connecting rod is arranged inside the snap ring, the bottom of the bottom connecting rod is fixedly connected to the outer surface of the base, and the bottom connecting rod is arranged directly below the electrical connecting rod.

[0015] The utility model discloses a water-washable integrated electric toothbrush, and the beneficial effects thereof are as follows:

[0016] When charging the water-washable integrated electric toothbrush, the user places the bottom of the toothbrush body downwardly against the base. Then, the bottom connecting rod inside the base presses the electrical connecting rod upward, so that the spring is compressed, and thus the magnetic attraction block and the connecting conductor are adsorbed to each other, so that the toothbrush body is electrically connected to the base, and the electric toothbrush starts to charge. After charging is completed, the spring expands, and then drives the positioning plate to move upward, so that the sealing ring at the bottom of the positioning plate blocks the connection port between the electrical connecting rod and the toothbrush body, making the bottom of the toothbrush body have better sealing performance, preventing water from entering the inside of the toothbrush body. At the same time, when not charging, the electrical connecting rod at the bottom of the toothbrush body is not connected to the circuit inside the toothbrush body, reducing the probability of damage to the toothbrush circuit due to water ingress.

The top of the brush handle 2 is fixedly connected with a brush head 201. A base 3 is arranged at the bottom of the toothbrush main body 1. The base 3 is used to position the toothbrush main body 1. A washable mechanism 4 is arranged at the bottom of the toothbrush main body 1. The washable mechanism 4 is used to prevent water from entering the inside of the toothbrush main body 1. The washable mechanism 4 includes:

[0027] An electrical connecting rod 401, the electrical connecting rod 401 is connected to the inside of the toothbrush main body 1, and the electrical connecting rod 401 is used for electrically connecting the base 3 and the toothbrush main body 1;

[0028] A spring 402, the bottom of the spring 402 is fixedly connected to the inside of the toothbrush main body 1, and the spring 402 is used to adjust the position of the electrical connecting rod 401;

[0029] A sealing ring 406 is fixedly connected to the outer surface of the electrical connecting rod 401. The top of the sealing ring 406 is fixedly connected with a positioning plate 403. The inner wall of the positioning plate 403 is fixedly connected to the outer surface of the electrical connecting rod 401.

[0030] The top of the spring 402 is fixedly connected to the bottom of the positioning plate 403, and the positioning plate 403 is slidably connected to the inside of the toothbrush main body 1.

[0031] A magnetic attraction block 404 is fixedly connected to the top of the electrical connection rod 401. Above the magnetic attraction block 404, there is a connection conductor 405. The bottom of the connection conductor 405 is fixedly connected to the inner wall of the toothbrush main body 1, and a switch 101 is arranged on the outer surface of the toothbrush main body 1.

[0032] A card slot 303 is arranged at the bottom of the toothbrush main body 1. A snap ring 302 is movably clamped inside the card slot 303, and the bottom of the snap ring 302 is fixedly connected to the inner wall of the base 3.
