SUCTION WATER-SUPPLY TYPE MOUTH CAVITY CLEANING BRUSH HEAD

摘要

To provide a mouth cavity cleaning device in which suction and water-supply can be performed simultaneously, the device can be used safely and easily without using a pump for water supply.SOLUTION: A suction passage 3 and a water-supply passage 4 are fixed to a cleaning head 2, and a suction opening 14 and a water-supply opening 15 are provided at a bottom surface 16. An outer peripheral part 17 surrounding a whole circumference by protruding from the bottom surface 16 is formed in an outer wall-like shape using a non-air-permeable member. When a tip 18 of the outer peripheral part is brought into contact with a cleaned surface during mouth cavity cleaning, a closed space is formed between the bottom surface 16, the outer peripheral part 17, and a mucosa in a mouth cavity and water is supplied by a negative pressure by suction force.SELECTED DRAWING: Figure 2
