Title:
PORTABLE DISINFECTING ELECTRIC TOOTHBRUSH AND PORTABLE DISINFECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/020979
Kind Code:
A1
Abstract:
A portable disinfecting electric toothbrush, comprising a toothbrush body (20) having a power source(10), a brush head (21) extending outwards from one end of the toothbrush body (20), and a brush cover (30) for covering the brush head (21) in a received state. An ultraviolet disinfection lamp (41) is arranged inside the brush cover (30). The inner wall of the brush cover (30) is provided with a wire (39) electrically connected to the ultraviolet disinfection lamp (39) and a power acquisition contact point (51) positioned outside the brush cover (30) and connected to the wire (39). A power supply contact point (52) corresponding to the power acquisition contact point (51) is provided at one end of the toothbrush body (20) that is close to the brush head (21). The power supply contact point (52) is connected to the power source (10) in the toothbrush body (20). Placement of the ultraviolet disinfection lamp (41) inside the brush cover (30) and adoption of the brush cover (30) as a disinfecting cavity can protect the brush head (21) and achieve disinfection. A spring (39) is used as the wire (39) and produces an outbound elastic force to a metal pin (51A), thus helping preserve good electric contact between the power acquisition contact point (51) and the power supply contact point (52). A UV control board (40) is mounted so as to be inclined with respect to the brush cover (30), and the ultraviolet disinfection lamp (41) is arranged close to the brush head (21), such that the entire brush head is illuminated as much as possible.
