[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4As shown, the present invention provides a technical solution: an oral toothbrush, comprising: a lighting component 1 and a grip component 2. The lighting component 1 consists of a connecting tube 101, a battery box 102, a switch 103 and a light 104. The battery box 102 is installed on one side of the connecting tube 101, the switch 103 is installed on the surface of the connecting tube 101, and the light 104 is provided on one side of the switch 103.
[0021] The grip assembly 2 consists of a rubber ring 201 and a hand buckle 202. The rubber ring 201 is mounted on the surface of the battery box 102, and the hand buckle 202 is fixedly connected to the side of the rubber ring 201. The connecting tube 101 fixes the battery box 102. The battery box 102 can store batteries to power the lighting lamp 104. The user can manually control the switch 103 to control the lighting lamp 104 to turn on and off. When the user inserts the connecting tube 101 into the patient's mouth for cleaning, the lighting lamp 104 provides illumination. The battery box 102, switch 103 and lighting lamp 104 are electrically connected, which can assist the operator in examining the inside of the mouth and suctioning out sputum and rinsing fluid. It can also clean teeth, improving cleaning efficiency and reducing the difficulty of cleaning for the user. The user holds the rubber ring 201, which fits against the patient's thenar eminence and the inside of the palm to increase friction and prevent the hand from slipping during cleaning. The user can insert fingers into the hand buckle 202 to grip the device, further stabilizing the grip.
