technical field

The utility model relates to a tooth cleaning tool, in particular to a toothbrush.

Background technique

Common toothbrushes include manual toothbrushes and automatic toothbrushes. The bristles of ordinary manual toothbrushes have a small area, and the direction of brushing needs to be adjusted constantly during use. It is not convenient enough, and it is easy to miss the parts of the inner teeth, resulting in the inability to fully clean the dirt and food residue on the tooth surface , and only part of the force that a person acts on the toothbrush acts in the direction needed to clean the teeth. To thoroughly clean the teeth, it is necessary to apply more force to the brush handle. And automatic toothbrush has complicated structure, high manufacturing cost, although it is better than common manual toothbrush to use effect, it is more difficult to popularize and apply. Chinese invention patent CN103416956A discloses a toothbrush, including a toothbrush handle and a toothbrush head. Toothbrush bristles are used to brush the inside of the teeth, so the bristles on the side that are not facing the teeth are likely to damage the mucous membranes and skin tissues in the oral cavity when using the toothbrush, and the comfort level of use is not high and unsafe.

In order to solve the above technical problems, the technical solution provided by the utility model is:

A toothbrush, comprising a brush handle, one end of the brush handle is connected with an arc-shaped brush holder, wherein: a flexible rod is arranged inside the arc-shaped brush holder, bristles are fixed on the flexible rod, and the arc-shaped brush holder corresponds to the bristles There is a bristle groove to facilitate the rotation of the bristles. A joint ball is provided at the end of the connection between the brush handle and the arc-shaped brush holder. The support is hingedly fitted in the card ball groove through the joint ball card.

In order to optimize the above technical solutions, the specific measures taken also include:

Further, the flexible rod is connected with a motor capable of rotating the flexible rod and a power supply for powering the motor, and a switch capable of controlling the opening and closing of the motor circuit is provided on the brush handle.

Further, the arc-shaped brush holder has a length of 4 cm to 8 cm.

Further, the length of the brush handle is 2 cm to 5 cm.

Further, the end of the brush handle away from the arc-shaped brush holder is provided with a brush handle protrusion for easy handling. There is a detachable fixed connection between the bristles and the flexible rod.

Further, the bristles are arranged symmetrically.

Further, the bristles are arranged in clusters, and there are gaps between two adjacent clusters of bristles.

Compared with the prior art, the beneficial effects of the utility model are:

1. The arc-shaped brush holder fits the shape of human gums.

When brushing the outside of the teeth, the bristles are located on the inner arc side of the arc-shaped brush holder, which can easily clean the teeth in different parts of the outside of the teeth.

By using the switch on the brush handle, the motor drives the flexible rod to rotate, and the bristles fixed on the flexible rod also rotate together, and turn to the outer arc side of the arc-shaped brush holder, which fits the inside of the human mouth, which can effectively clean teeth The inner side is not easy to damage the mucous membrane and skin tissue in the oral cavity.

Depending on the size of the mouth, it can be designed into different models such as adult toothbrush and children's toothbrush.

2. The connecting part of the toothbrush handle and the brush holder has been improved, so that the brush handle can swing freely when brushing teeth, and the teeth can be cleaned only by moving the wrist, which is more convenient to use.

3. More time-saving and labor-saving than traditional manual toothbrushes.

4. The bristles can be replaced. When you need to replace a new toothbrush, you only need to remove the bristles on the flexible rod and replace them with new ones. The brush handle, brush holder and flexible rod can be reused, which is energy-saving and environmentally friendly.

5. The toothbrush is simple in structure, easy to manufacture, low in cost, and easy to popularize.
