Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model provides Figure 1-3 The sterilizable water flosser shown in the figure comprises a main shell 1, a battery 2 and a micro water pump 3 installed in the main shell 1, a water inlet assembly 4 installed at the input end of the micro water pump 3, a water tank 5 of a transparent material slidably connected to the bottom of the main shell 1, and a nozzle 6. The micro water pump 3 is electrically connected to the battery 2. A receiving groove 7 and a rotating groove 8 are opened on one side of the main shell 1. A Y-shaped tube 9 is fixedly installed at the output end of the micro water pump 3. Both ends of the Y-shaped tube 9 away from the micro water pump 3 penetrate the main shell 1 and are inserted into the rotating groove 8. A hollow cylinder 10 rotatably connected to the Y-shaped tube 9 is arranged in the rotating groove 8. The nozzle 6 is installed on the hollow cylinder 10, and the water tank 5 has a U-shaped accommodating cavity 12. An ultraviolet light strip 11 is installed in the accommodating cavity 12. The end of the ultraviolet light strip 11 away from the accommodating groove 7 passes through the top of the water tank 5 and is fixedly connected with a contact 13. A block 14 is fixedly installed on one side of the outer wall of the main shell 1, and a power-on terminal that cooperates with the contact 13 is installed at the bottom of the block 14. The power-on terminal is electrically connected to the battery 2. The outer peripheral surface of the hollow cylinder 10 has a through hole 15, and the inner peripheral surface of the through hole 15 has a rubber film. The bottom end of the nozzle 6 is interference fit with the through hole 15.

[0025] The user inserts the bottom end of the nozzle 6 into the through hole 15, and uses the elasticity of the rubber material to make the nozzle 6 and the through hole 15 have an interference fit, thereby installing the nozzle 6 on the hollow cylinder 10;

[0026] The user starts the micro water pump 3, and the micro water pump 3 pumps the water in the water tank 5 into the Y-shaped tube 9 through the water inlet assembly 4, and then introduces the water into the nozzle 6 through the hollow cylinder 10, thereby achieving the purpose of flushing teeth;

[0027] After the water in the water tank 5 is used up, the user turns the nozzle 6 so that the nozzle 6 drives the hollow cylinder 10 to rotate on the Y-shaped tube 9 until the nozzle 6 is screwed into the receiving groove 7, and then the user presses the main shell 1 into the water tank 5 until the contact 13 contacts the power-on terminal. At this time, the battery 2 supplies power to the ultraviolet light strip 11 through the power-on terminal and the contact 13, and the ultraviolet light strip 11 irradiates and disinfects the nozzle 6, the inner wall of the water tank 5 and the bottom surface of the main shell 1.
