An adjusting tube 6 is fixedly connected to the lower end of the adjusting ring 3, and the lower end of the push rod 4 extends movably into the adjusting tube 6. Rotating the adjusting tube 6 causes the adjusting ring 3 to rotate, and the rotation of the adjusting ring 3 drives the push rod 4 to move longitudinally in a linear motion, thereby causing the push plate 5 to move longitudinally. The push plate 5 can be made of medical-grade material. Made of elastic sealing materials such as rubber, its outer surface is tightly fitted to the inner wall of the receiving tube 1 for sealing and pushing chemical agents. The two mounting plates 2 are connected to positioning rings 12 at opposite ends. The lower positioning ring 12 is fixedly connected to the lower mounting plate 2, and the upper positioning ring 12 is rotatably connected to the upper mounting plate 2. The positioning ring 12 is covered with a protective shell 19. The positioning ring 12 is made of magnetic material. The protective shell 19 attracts the positioning ring 12. The adjusting tube 6 is located inside the lower protective shell 19. The lower protective shell 19 can protect the adjusting tube 6 and effectively reduce the accidental rotation of the adjusting tube 6 caused by external impact.

[0022] Please see Figure 2 , Figures 4-7 The upper end of the mounting plate 2 is fixedly connected to a mounting ring 7. Two insertion holes 8 are carved into the surface of the mounting ring 7, and a limiting groove 9 communicating with the insertion holes 8 is carved inside the mounting ring 7. Two sliding grooves 10 are carved into the outer ring surface of the mounting ring 7, communicating with the limiting grooves 9. Two sliders 11 are slidably connected within the limiting grooves 9. One end of each slider 11, away from the central axis of the mounting ring 7, movably passes through the sliding groove 10 and is fixedly connected to the upper positioning ring 12. The surface of the slider 11 is provided with anti-slip texture. A replacement head is provided at the upper end of the mounting ring 7, located inside the upper protective shell 19. The replacement head includes two movable insertion blocks 13 that pass through the insertion holes 8. One end of the slider 11 moves through one of the insert blocks 13. The upper ends of the two insert blocks 13 are fixedly connected to a positioning plate 14. The lower end of the positioning plate 14 is fixedly connected to a positioning block 15.

This head is only used for dry cleaning and does not involve the delivery of chemical agents. The mounting rod 164 is a solid rod and only serves as a support during use to prevent the chemical agents in the container tube 1 from leaking out.

[0025] Model 3: Please refer to Figure 9 The cleaning head 16 includes a positioning rod 166 fixedly connected to the upper end of the positioning plate 14. A toothbrush 167 is fixedly connected to the upper end of the positioning rod 166. Both the positioning rod 166 and the toothbrush 167 are hollow structures. Multiple discharge holes 168 are drilled at the left end of the toothbrush 167. Before brushing the teeth with the toothbrush 167, the position of the push plate 5 can be adjusted by rotating the adjusting tube 6. The chemical agent is discharged from the discharge holes 168 on the toothbrush 167. While the bristles clean the tooth surface, the chemical agent is evenly distributed in the oral cavity.

[0026] When using the oral cleaning device, according to the current care needs (such as need 1: using chemical agents to clean between teeth, the corresponding cleaning head 16 is model 1; need 2: using dental floss, the corresponding cleaning head 16 is model 2; need 3: combining the effects of brushing teeth and using chemical agents to clean between teeth, the corresponding cleaning head 16 is model 3), select the appropriate cleaning head 16 to perform the installation operation: remove the upper magnetic protective shell 19 to expose the mounting ring 7, align the pair of inserts 13 with the pair of insert holes 8 on the mounting ring 7 and insert them. At this time, the positioning block 15 is located inside the mounting ring 7. Gently rotate the upper positioning ring 12 to drive the internal slider 11 to move along the slide groove 10 until the inserts 13 are firmly locked in the limiting groove 9; When selecting cleaning head 16 of model one or model three, after installation, slowly rotate the adjusting tube 6 at the bottom of the device according to the required dosage of chemical agent. Through the internal threaded transmission mechanism, push rod 4 and push plate 5 up a short distance, pushing the chemical agent to the outlet. After completing the preparation before use, oral cleaning can begin. During the cleaning process, chemical agent can be replenished as needed: rotate the bottom adjusting tube 6 again to precisely control the pushing distance of push plate 5, delivering an appropriate amount of chemical agent to the working part of cleaning head 16. Throughout the entire use process, the user does not need to change the main unit; simply by selecting different heads, they can complete a full set of oral health management, from fine interdental care to comprehensive brushing, greatly improving the applicability and convenience of the product.

[0027] Example 2: This embodiment adds an installation tube 17 and a sealing plug 18 to Example 1, while the rest remains the same as the first embodiment.

[0028] Please see Figure 10 The right end of the receiving tube 1 is fixedly connected to the installation tube 17, and the installation tube 17 is internally threaded with a sealing plug 18.

[0029] After the chemical preparation inside the container tube 1 is used up, the adjusting tube 6 can be rotated to reset the push rod 4 and push plate 5 inside the container tube 1. Then, the sealing plug 18 can be removed, and the chemical preparation can be injected into the container tube 1 through a syringe-like delivery tool.
