Problems solved by technology

Because the brush head and the brush rod of the traditional toothbrush are integrated, the rotation of the brush head is not flexible. During use, it cannot fully clean all parts of the teeth, especially the gums, so that residual food accumulates on the surface of the teeth. Excessive force will also wear the gums , and the entire toothbrush will be useless after the brush head is damaged, wasting resources
Existing electric toothbrushes have complex structures and high costs

Description

Technical field: [0001] The invention relates to a toothbrush, in particular to a reciprocating electric toothbrush. Background technique: [0002] Toothbrush is a kind of article of daily use that is requisite in people's daily life. Because the brush head and the brush rod of the traditional toothbrush are integrated, the rotation of the brush head is not flexible. During use, it cannot fully clean all parts of the teeth, especially the gums, so that residual food accumulates on the surface of the teeth. Excessive force will also wear the gums , and the whole toothbrush will be useless after the brush head is damaged, wasting resources. Existing electric toothbrushes are complicated in structure, and the cost is very high. Invention content: [0003] The purpose of the present invention is to provide a simple in structure, economical and practical reciprocating electric toothbrush. The present invention is composed of a brush head 1, a brush rod 2 and a housing 3. The...
