[0002] At present, oral hygiene is receiving more and more attention. In order to meet consumers' demand for toothbrush use, the comfort and cleaning power of toothbrushes also need to be enhanced.

[0003] However, the current electric toothbrush heads are limited by the shape and type of bristles, which results in poor cleaning power on the tooth surface, or makes it difficult for the toothbrush to clean the deep gum line area or gingival sulcus area, and the cleaning effect is not good enough. In addition, during the production process of current electric toothbrush heads, the rubber coating of the toothbrush heads is usually simply wrapped on the toothbrush heads from the outside, and the rubber coating is not strong enough and is easily separated due to vibration and erosion by toothpaste and mouthwash. Utility Model Content

The front of the brush head is provided with a hair-planting surface, and the hair-planting surface is provided with a plurality of hair-planting holes. Brush filaments are installed inside the hair-planting holes. The plurality of hair-planting holes are divided into a front area, a middle area, and a rear area. The hair-planting holes located in the front area are inclined forward at an angle of four degrees. The brush head is covered with soft rubber. The tail end of the brush handle is a hollow section, and a tail plug mounting position is provided inside the hollow section. A tail plug is provided inside the tail plug mounting position. A buckle position is provided inside the tail plug mounting position. A fixing bone is provided on the left and right sides of the tail plug mounting position, and a fixing positioning plane is provided below and between the two fixing bones. A fixing positioning connecting surface, a square groove, an annular groove, and a main shaft mounting hole are provided on the tail plug. The buckle position is connected to the annular groove, and the fixing positioning connecting surface is connected to the fixing positioning plane.

[0007] As a further improvement of the present invention, the top end of the brush filament is in a half-moon shape.

[0008] As a further improvement of the present invention, the top end of the brush filament is in an arc shape, and the front section of the arc is provided with a downward slope to form a hill-like protrusion.

[0009] As a further improvement of the utility model, a butterfly-shaped groove is provided on the hair-implanting surface, and four through holes are penetrated through the inner wall of the butterfly-shaped groove.

[0010] As a further improvement of the present invention, a reinforcing rib is provided on the back of the brush head.

[0011] As a further improvement of the utility model, both sides of the soft rubber are provided with rubber buffer pads.

[0012] Beneficial effects of the utility model:

[0013] 1. By tilting the hair transplant holes in the front area at an angle of four degrees forward, when brushing your teeth, the brush head moves forward for cleaning, and is subjected to force longitudinally in the running direction. The brush wires are less deformed, have better support, stronger thrust, and better cleaning effects.

[0014] 2. The hair transplant pores are divided into the front area, the middle area and the back area. When brushing your teeth, three teeth can be cleaned at the same time. The brush wires in the front area can perform strong cleaning, the brush wires in the middle area can clean the dirt cleaned from the front area, and the brush wires in the back area can further strengthen the cleaning of the uncleaned areas in the front and middle areas.

[0015] 3. By designing the top of the brush wire into a half-moon shape, the arc surface contacts the teeth more, and the cleaning effect on the toothbrush surface is stronger; by making the top of the brush wire into an arc shape, and the front section of the arc has a downward slope, a hill-like protrusion is formed, which can better enter the gaps between teeth, deeply clean the gaps between teeth, and have a good cleaning effect on the gaps between teeth.

[0016] 4. By designing through holes and butterfly grooves, the soft rubber on the front and back of the brush head can form a whole and be completely wrapped around the outside of the brush head. The soft rubber will be firmly fixed and will not separate due to vibration and erosion by toothpaste or mouthwash.

[0017] The utility model effectively improves the cleaning effect through the zoning design of the implant pores and the design of the brush wire shape, and the soft glue will be firmly fixed and will not be separated due to vibration and erosion by toothpaste and mouthwash.
