Technical Field

The utility model relates to the technical field of toothbrushes, in particular to a bending electric toothbrush.

Background

The toothbrush is an essential living tool in daily life, and people need to brush teeth in the morning and at night every day in life, so that the toothbrush can clean the oral cavity, massage the gums, promote blood circulation and enhance disease resistance. However, most of the toothbrushes sold in the market, whether traditional manual toothbrushes or current popular electric toothbrushes, are composed of a brush head and a brush handle, but due to the problems of the structure of the toothbrushes, the toothbrushes can better clean the outer sides of teeth, are difficult to clean stains on the inner sides of the teeth, and need to brush teeth from different angles for several times, so that the operation is troublesome, time is wasted, and people cannot effectively clean the teeth in a short time. Food waste is usually left on the inner sides of teeth because dead corners on the inner sides of the teeth cannot be cleaned, pathogenic bacteria can be bred after long-term residue, and oral diseases can be caused.

Disclosure of Invention

In order to solve the above problems, the utility model provides a bending electric toothbrush, which can conveniently brush the dead angle of the inner side of the teeth, thereby improving the cleaning rate of the teeth.

In order to achieve the above object, the utility model provides a curved electric toothbrush, including brush head and brush holder, the brush head is installed in the brush holder, the brush head includes brush hair portion and connection handle, brush hair portion is connected with the connection handle, the connection handle includes first handle section and second handle section, first handle section and second handle section rounding off, first handle section and second handle section are connected and are formed crooked.

Preferably, the angle of curvature between the first shank segment and the second shank segment is θ, the degree of θ being from 95 ° to 125 °.

Preferably, the angle θ is 120 °.

Preferably, the bristle part comprises bristles and a bristle planting seat, the bristles are planted in the bristle planting seat, and the bristle planting seat is connected with the connecting handle.

Preferably, an ultrasonic motor and a power supply assembly are arranged in the brush handle, the power supply assembly is electrically connected with the ultrasonic motor, and an output shaft of the ultrasonic motor extends out of the brush handle and is in driving connection with the connecting handle.

As a preferred scheme, the connecting handle is provided with an installation groove matched with the output shaft of the ultrasonic motor, and the connecting handle is clamped with the output shaft of the ultrasonic motor through the installation groove.

The beneficial effects of the utility model reside in that:

the utility model changes the angle between the brush head and the brush handle, and the connecting handle of the brush head is set to be curved, thereby realizing the purpose that the dead angle position inside the teeth can be effectively washed by the up-and-down movement of the brush handle, improving the tooth cleaning rate, avoiding the need of horizontally moving the arm, and greatly reducing the fatigue degree of the arm; in addition, the brush head and the brush handle are detachably connected, so that the brush head is convenient to replace when a common normal brush head is required to be selected, and the utility model has the advantages of low production and manufacturing cost and convenience for large-scale production.
