Unilateral oral cleaning mouth opening aid

Abstract

This invention discloses a unilateral oral cavity cleaning mouth-opening aid, mainly comprising a body and a support portion. The body is a flexible, elongated U-shaped structure with an occlusal surface and two side surfaces. Its central position is bent vertically to form an upper and lower occlusal groove, and the two grooves are bent horizontally in the same direction to conform to the arc of the dentition and fit the oral cavity shape. The support portion is a flexible sheet disposed in the angled space between the upper and lower occlusal grooves, with its outer edge protruding relative to the edges of the two grooves. The elastic modulus of the body is higher than that of the support portion. This structure helps the user maintain a proper mouth opening when cleaning one side of the mouth, improving cleaning efficiency and safety.

Claims

1. A unilateral oral cavity cleaning mouth-opening aid, comprising: a body, which is a flexible structure, and the body is an elongated U-shaped body having a biting surface and two side surfaces, and is bent vertically in the middle to form an upper biting groove and a lower biting groove, and the upper biting groove and the lower biting groove are bent horizontally in the same direction; a support portion, which is a flexible sheet body, and the support portion is placed in the angle space between the upper biting groove and the lower biting groove; wherein, The outer edge of the support portion protrudes relative to the edge of the upper and lower bite grooves, and the elastic modulus of the body is greater than that of the support portion; two LED light strips are respectively disposed on the outer surface of the two sides; a driving circuit is electrically connected to the LED light strips, the driving circuit is embedded in the clamping surface along the position from the upper bite groove to the lower bite groove, and has a contact switch in the upper bite groove and the lower bite groove respectively; and a power module is electrically connected to the driving circuit, the power module is disposed at the clamping surface position at the bend between the upper bite groove and the lower bite groove; wherein, when the upper bite groove and the lower bite groove clamp with force, the driving circuit will be electrically changed from a double-ended open circuit to a closed circuit, thereby driving the LED light strips to emit light.

2. The unilateral oral cavity cleaning mouth-opening device as described in claim 1, wherein, The outer end of the support has a tension hole.

3. The unilateral oral cavity cleaning mouth-opening device as described in claim 1, wherein, The outer ends of the support are recessed inward on both sides, and the outer contour edge is expanded outward.
