Toothpaste-dispensing toothbrush with a replaceable brush head

Abstract

A toothpaste-dispensing toothbrush includes a replaceable brush head, a pump head, a truncated dispensing platform attached with a spout, and a handle containing toothpaste. The brush head has a through hole and a stepped backside mating with the truncated dispensing platform by a set of latch mechanisms. The detachment of the brush head requires two steps by using two hands to rotate the brush head then push it off from the dispensing platform. The brush head is provided with an extended lever segment having a latch notch and the truncated dispensing platform has an extended neck portion having a neck post for engaging with the lever notch for additional locking. The stepped backside enables the brush head to brush back teeth with comfort. The applications of the replaceable brush head to a manual toothbrush and a toothpaste-dispensing electric toothbrush are provided.
