[0045] The present application will be further described in detail below with reference to the accompanying drawings through specific embodiments.

[0046] Embodiment 1

[0047] Referring to Figure 1 and Figure 2 as shown, the oral irrigator includes: a main body 1, a water tank 2 and a nozzle assembly 3;

[0048] The nozzle assembly 3 is adsorbed on the outer periphery of the housing 11 of the main body 1 through a magnetic structure for easy use and storage;

[0049] Referring to Figures 1 to 3As shown, the housing of the main unit 1 is provided with a water tank mounting part 12 at its upper end. The water tank mounting part 12 is provided with a housing water inlet 13 that communicates with the water pumping assembly 14 inside the housing. The bottom of the water tank is provided with a water tank water outlet. After the water tank is arranged in the water tank mounting part 12, the water tank water outlet communicates with the housing water inlet 13. The water pumping assembly 14 includes a motor, a water pump and a transmission structure. The water inlet of the water pump communicates with the housing water inlet 13. The water pumping assembly 14 is used to pump the cleaning liquid for cleaning teeth in the water tank to the nozzle assembly 3 at a preset pressure. Arranging the water tank at the upper end of the housing is convenient for the user to add the cleaning liquid on the one hand. The user can directly add the cleaning liquid or remove the water tank to add it. On the other hand, the gravitational potential energy of water can be used to reduce the load of the water pump. Arranging the water tank water outlet at the lower end of the water tank can make the use of the cleaning liquid more thorough and reduce the residue of the cleaning liquid in the water tank. The main unit 1 is provided with a control component. The motor drives the water pump to work through the transmission structure. The control component can change the working parameters such as the speed, power and torque of the motor according to the user's operation. Based on the change of the motor working parameters, the flow rate, flow, frequency and pressure of the cleaning liquid pumped by the water pump change accordingly, so that the user can obtain a comfortable and necessary cleaning liquid flushing intensity.

[0050] Further referring to Figures 3 to 5 As shown, an air pump 151, a solenoid valve 152 and a sand storage bottle 16 are arranged inside the main unit 1. The air pump 151 is connected to the valve body air inlet 1521 of the solenoid valve 152 through a pipeline. The control component can control the valve core of the solenoid valve 152 to change its direction according to the user's operation, so that the solenoid valve 152 changes the communication state between its first exhaust port 1522 and second exhaust port 1523 and the valve body air inlet 1521. The first exhaust port 1522 of the solenoid valve 152 communicates with the nozzle assembly 3. The second exhaust port 1523 of the solenoid valve 152 communicates with the bottle body air inlet 161 of the sand storage bottle 16. The bottle body sand blasting port 162 of the sand storage bottle 16 communicates with the nozzle assembly 3. The valve core of the solenoid valve 152 is normally in a state where the first exhaust port 1522 communicates with the valve body air inlet 1521. Based on the user's selection, the control component issues a control signal to make the valve core of the solenoid valve 152 change its direction, which can make the second exhaust port 1523 communicate with the valve body air inlet 1521. The gas pumped by the air pump 151 enters the sand storage bottle 16 through the valve body air inlet 1521, the second exhaust port 1523 and the bottle body air inlet 161. The compressed gas entering the sand storage bottle 16 entrains the sand material in the sand storage bottle 16 and then sprays out from the bottle body sand blasting port 162. The bottle body sand blasting port 162 is connected to the nozzle assembly 3 through a pipeline so that the compressed gas mixed with the sand material is sprayed out from the nozzle 34.

[0051] After the water vapor in the air enters the above-mentioned gas path through the air pump 151, it may condense and accumulate in the pipeline and other components of the gas path. The liquid in the pipeline and other components of the gas path may damage the pipeline and other components that make up the gas path; further, the liquid in the pipeline and other components of the gas path will block the pipeline and other components of the gas path after being mixed with the abrasive material. On the other hand, impurities in the air will block or damage the pipeline and other components of the gas path; therefore, as a preferred implementation method, an air storage tank 153 is provided between the solenoid valve 152 and the air pump 151, or an air storage tank 153 is provided between the solenoid valve 152 and the sand storage bottle 16. The air storage tank 153 has gas drying and filtering components to filter the moisture and impurities in the air. At the same time, the air storage tank 153 can make the air pressure of the compressed gas entering the solenoid valve 152 or the sand storage bottle 16 more stable, and users can obtain a better user experience when choosing the sandblasting or air jetting mode.

[0052] To facilitate the user to add abrasive material, the sand storage bottle 16 includes a sand bottle body 164 and a sand bottle cap 163. The sand bottle cap 163 is exposed outside the housing. As a preferred implementation method, the sand bottle cap 163 protrudes from the upper end face of the housing. After the user unscrews the sand bottle cap 163, the user can add abrasive material into the sand bottle body 164; the abrasive material added to the sand bottle body 164 is composed of one or more of sodium bicarbonate, glycine, silicate particles, fluoride, remineralizer, anti-plaque agent, anti-tartar agent, anti-gingivitis agent, and antibacterial agent.

[0053] For further reference Figures 6 to 18 As shown in the figure, the nozzle assembly 3 includes a grip handle 31. The grip handle 31 is composed of a front cover 311 and a rear shell 312 that are snap-fitted. In order to make the assembly of the front cover 311 and the rear shell 312 stable, self-tapping screws 314 are used to further fasten between the front cover 311 and the rear shell 312. A handle cavity 313 is formed between the front cover 311 and the rear shell 312. A nozzle fixing seat 32 that is clamped between the front cover 311 and the rear shell 312 is provided at the front end of the grip handle 31. A first fixing seat interface 321 and a second fixing seat interface 322 are provided at the lower end of the nozzle fixing seat 32; the first fixing seat interface 321 is communicated with the water outlet of the water pump; the second fixing seat interface 322 is communicated with the sandblasting port 162 of the bottle body and the first exhaust port 1522. The pipeline connecting the sandblasting port 162 of the bottle body and the pipeline connecting the first exhaust port 1522 are merged through a confluence component. The confluence component can use a Y-shaped three-way pipe joint, etc. The confluence component is then communicated with the second fixing seat interface 322 through a pipeline to realize the communication between the second fixing seat interface 322 and the sandblasting port 162 of the bottle body and the first exhaust port 1522 of the solenoid valve 152;

[0054] For further reference Figure 16As shown, a columnar first chamber 323 is formed at the upper end of the nozzle fixing base 32. The nozzle fixing base 32 forms a fixing base isolation ring 324 at the bottom of the first chamber 323. The fixing base isolation ring 324 surrounds and forms a second chamber 325. The bottom of the second chamber 325 is communicated with the second interface. The bottom of the annular space determined by the fixing base isolation ring 324 and the inner wall of the first chamber 323 is communicated with the fixing base first interface 321;

[0055] Further referring to Figure 10 and Figure 13 As shown, a nozzle adapter component 33 is connected to the upper end of the nozzle fixing base 32. The nozzle adapter component 33 is composed of a first nozzle adapter body 331 and a second nozzle adapter body 332; the diameter of the first nozzle adapter body 331 matches the inner diameter of the first chamber 323, and the diameter of the second nozzle adapter body 332 matches the inner diameter of the second chamber 325; a communicating first adapter flow channel 333 is provided between the upper end surface of the first nozzle adapter body 331 and the outer periphery of the nozzle adapter component 33, and a communicating second adapter flow channel 334 is provided between the upper end surface of the first nozzle adapter body 331 and the lower end surface of the second nozzle adapter body 332; corresponding to the first adapter flow channel, a first adapter flow channel outlet 3331 is formed on the upper end surface of the first nozzle adapter body 331, and a first adapter flow channel inlet 3332 is formed at the connection of the outer periphery of the nozzle adapter component 33, the first nozzle adapter body 331 and the second nozzle adapter body 332; corresponding to the second adapter flow channel, a second adapter flow channel outlet 3341 is formed on the upper end surface of the nozzle adapter component 33, and a second adapter flow channel inlet 3342 is formed on the lower end surface of the second nozzle adapter body 332;

[0056] Further referring to Figure 9 and Figure 15As shown, when the nozzle adapter component 33 is disposed on the nozzle fixing base 32, the second body 332 of the nozzle adapter is inserted into the second chamber 325, and the second flow channel of the adapter communicates with the second interface 322 of the fixing base; a second sealing ring 38 is provided between the outer periphery of the second body 332 of the nozzle adapter and the inner wall of the second chamber 325. The second sealing ring 38 prevents the fluid in the first chamber 323 from entering the second chamber 325 and the leakage of the fluid in the first chamber 323. To prevent the second sealing ring 38 from shifting, a second body groove 3321 for installing the second sealing ring 38 is provided on the outer periphery of the second body 332 of the nozzle adapter; at the same time, the first body 331 of the nozzle adapter is inserted into the first chamber 323, the first flow channel of the adapter communicates with the first interface 321 of the fixing base, and a first sealing ring 37 is provided between the outer periphery of the first body 331 of the nozzle adapter and the inner wall of the first chamber 323 to prevent the leakage of the fluid after it enters the first chamber 323. To prevent the first sealing ring 37 from shifting, a first body groove 3311 for installing the first sealing ring 37 is provided on the outer periphery of the first body 331 of the nozzle adapter.

[0057] Further referring to Figure 14 and Figure 16 As shown, a nozzle socket convex platform 335 for socketing the nozzle is provided at the upper end of the first body 331 of the nozzle adapter. Correspondingly, a nozzle socket groove 341 matching the nozzle socket convex platform 335 is provided at the lower end of the nozzle. The nozzle is formed with a first nozzle flow channel 342 and a second nozzle flow channel 343 penetrating in its extending direction. The inlets of the first nozzle flow channel 342 and the second nozzle flow channel 343 are provided at the bottom of the nozzle socket groove 341. When the nozzle is socketed on the nozzle adapter component 33, the inlet of the first nozzle flow channel 342 covers the outlet 3331 of the first flow channel of the adapter, and the inlet of the second nozzle flow channel 343 covers the outlet 3341 of the second flow channel of the adapter; in order to make the positions of the inlet of the first nozzle flow channel 342 and the outlet 3331 of the first flow channel of the adapter correspond to each other after the nozzle is installed, and the positions of the inlet of the second nozzle flow channel 343 and the outlet 3341 of the second flow channel of the adapter correspond to each other, an anti-fooling recess 344 is provided on the inner periphery of the nozzle socket groove 341, and an anti-fooling protrusion 336 corresponding to the anti-fooling recess 344 is provided on the outer periphery of the nozzle socket convex platform 335. The angle of connection between the nozzle and the nozzle adapter component 33 is fixed by the anti-fooling protrusion 336 being snapped into the anti-fooling recess 344. Corresponding to the inlet of the first nozzle flow channel 342 and the inlet of the second nozzle flow channel 343, a first nozzle flow channel outlet 342 and a second nozzle flow channel outlet 343 are provided at the other end of the nozzle.

[0058] The above structure can isolate sandblasting / air jetting from liquid spraying. The cleaning liquid is sprayed out through the outlet of the first flow channel 342 of the nozzle, and the compressed gas or the air-sand mixture is sprayed out from the outlet of the second flow channel 343 of the nozzle. When using the oral irrigator, the cleaning liquid and the compressed gas or the air-sand mixture are mixed on the tooth surface or in the oral cavity after being sprayed out through the nozzle, which can effectively prevent the cleaning liquid and sand material from mixing inside the oral irrigator and causing blockage of various components in the oral irrigator.

[0059] In order to adjust the flow rate of the cleaning liquid ejected from the nozzle, a regulating valve assembly 35 is provided in the handle cavity 313. The regulating valve assembly 35 includes a regulating valve body and a regulating valve core 352. The on-off state of the valve body flow channel provided in the regulating valve body 351 can be changed by twisting the regulating valve core 352 based on the regulating valve body 351.
