Title:
ORAL CAVITY VIEWING INSTRUMENT CONTAINING ELECTROMAGNETIC SHIELDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/042937
Kind Code:
A1
Abstract:
An oral cavity viewing instrument (200) containing an electromagnetic shielding system (500), the instrument containing a housing (4), a power supply system (5), a lighting system (6), a viewing system (7), a circuit system (8), a switch (9) and an electromagnetic shielding system (500). The electromagnetic shielding system (500) may be an electromagnetic shielding cover (50-1) or an electromagnetic shielding body (50-2); the electromagnetic shielding system (500) may reflect, absorb and attenuate electromagnetic waves generated by an electronic component of the oral cavity viewing instrument (200) containing the electromagnetic shielding system (500) so as to ultimately reduce electromagnetic interference, and the electromagnetic waves are shielded within the oral cavity viewing instrument (200) to ensure electromagnetic safety during use. When the oral cavity viewing instrument (200) containing the electromagnetic shielding system (500) is acted on by an external electric field, an electrostatic protection system (400) may also provide electrostatic protection for the electronic component within the oral cavity viewing instrument (200) containing the electromagnetic shielding system (500) so as to ensure the safe use of the oral cavity viewing instrument (200) containing the electromagnetic shielding system (500). The oral cavity viewing instrument (200) containing the electromagnetic shielding system (500) may also be connected to an oral cavity cleaning tool (201) by means of a connecting mechanism (300). Under real-time viewing by means of a camera (7-1-1), the oral cavity cleaning tool (201) may be used to clean an oral cavity, thereby achieving the real-time viewing of oral cavity cleaning and fixed-point cleaning; moreover, the use process is very convenient.
