Description

Technical Field

[0001] The utility model relates to the field of electric toothbrush heads, in particular to a foldable electric toothbrush head. Background Art

[0002] An electric toothbrush is a type of toothbrush that uses the rapid rotation or vibration of the electric motor to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have a massage effect on the gum tissue. The electric toothbrush head is a component of the electric toothbrush.

[0003] Most of the existing electric toothbrush heads are integral and cannot be folded, which is inconvenient to carry, and one brush head can only be adapted to one electric toothbrush, which has poor applicability. Therefore, those skilled in the art provide a foldable electric toothbrush head to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a foldable electric toothbrush head, which can be folded, and the noise generated during the operation of the electric toothbrush can be effectively reduced by the sound insulation sponge pad. The brush head body is detachable, and the brush head body and the brush rod can be quickly separated by the second connecting mechanism.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A foldable electric toothbrush head comprises a brush head body, wherein a damping hinge rod is fixedly arranged at the middle position inside the brush head body;

[0007] A first connection mechanism is fixedly disposed at the upper end of the brush head body, and a second connection mechanism is fixedly disposed at the lower end of the brush head body;

[0008] Through the above technical solution, the electric toothbrush head increases the overall flexibility by setting a damping hinged rod, so that the electric toothbrush head can be folded for better storage and protection of the brush head body. The first connecting mechanism can connect the brush head body and the connecting rod to facilitate disassembly of the brush head body. The second connecting mechanism can be used to connect the brush head body and the electric toothbrush.

[0009] Furthermore, the brush head body comprises a brush rod, and a placement groove is provided on the front side of the brush rod;

[0010] Through the above technical solution, the brush rod can be used to connect the various components of the brush head body, and the brush head body can be folded into the placement groove for storage and protection.

[0011] Furthermore, a connecting rod is hingedly provided at the upper end of the brush rod, and a brush head body is threadedly fixed at the upper end of the connecting rod;

[0012] Through the above technical solution, the connecting rod plays the role of connecting the brush head body and the brush rod, and the brush head body can be used to clean teeth.

[0013] Furthermore, the first connecting mechanism includes a fixing rod, a threaded groove and two first springs, and first magnetic blocks are fixedly arranged on both sides of the lower end of the fixing rod;

[0014] Through the above technical solution, the fixing rod plays a role in fixing the first magnetic block and the threaded rod, the threaded groove plays a role in fixing the threaded rod, and the first spring can drive the second magnetic block to move when it is compressed and expanded.

[0015] Furthermore, a threaded rod is fixedly provided at the middle position of the lower end of the fixing rod, and a second magnetic block is fixedly provided at the upper ends of the two first springs;

[0016] Through the above technical solution, the threaded rod can be used in conjunction with the threaded groove, and the first magnetic block and the second magnetic block have the same pole on the opposite side. When the threaded rod and the threaded groove are separated, the first magnetic block and the fixed rod can be quickly ejected due to the repulsion of the same poles, thereby realizing the rapid separation of the brush head body and the brush rod.

[0017] Furthermore, the second connection mechanism includes two second springs, and a fixing ring is fixedly provided on one side of the two second springs;

[0018] Through the above technical solution, the second spring is compressed to expand and contract and can move with the fixing ring. The second spring and the fixing ring can be used together to connect the electric toothbrush head to electric toothbrushes of different specifications, thereby increasing the overall flexibility.

[0019] Furthermore, a sound insulation sponge pad is fixedly provided on one side of the two fixing rings;

[0020] Through the above technical solution, the sound insulation sponge pad can block the noise generated when the electric toothbrush is in operation, thereby helping to reduce the noise generated when the electric toothbrush is in operation.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a foldable electric toothbrush head, which connects the connecting rod and the brush rod through a damping hinged rod, so that the electric toothbrush head can be folded, and the brush head body can be folded into the placement groove, which can effectively protect the brush head body when the brush head body is not in use. By using a second spring and a fixing ring in combination, it can be connected to the connecting structure of electric toothbrushes of different specifications to achieve the connection between the electric toothbrush head and the electric toothbrush body. The sound insulation sponge pad can be used to block the noise generated during the operation of the electric toothbrush, thereby effectively reducing the noise generated during the operation of the electric toothbrush.

[0023] 2. The utility model proposes a foldable electric toothbrush head, which can connect the brush head body and the brush rod by using the provided threaded rod and threaded groove in combination. The brush head body is detachable. When disassembling, it is only necessary to separate the threaded rod and the threaded groove. At this time, the first spring is no longer under pressure and will expand and contract, and drive the second magnetic block to move. Due to the repulsion of like poles, the second magnetic block can quickly push the first magnetic block and the fixed rod out of the connecting rod when it moves, thereby realizing the rapid separation of the brush head body and the brush rod.
