[0051] Specifically, the biting portion 11 is arranged in a U shape, which conforms to the human oral structure, facilitating the placement of the biting portion 11 into the human oral cavity. Moreover, an upper U-shaped groove 111 is opened at the top of the biting portion 111, and a lower U-shaped groove 112 is opened at the bottom. The user can conveniently place the upper and lower rows of teeth into the upper U-shaped groove 111 or the lower U-shaped groove 112 by biting, and fix the biting portion 11 by biting, eliminating the need for the user to hold the cleaning head body 1 for a long time;

[0052] Preferably, the cleaning component 12 includes an upper cleaning part and a lower cleaning part. The upper cleaning part is uniformly arranged on the inner walls on both sides of the upper U-shaped groove 111 along the arc direction of the upper U-shaped groove 111, and is used to spray gas or cleaning liquid on the inner and outer sides of the tooth surfaces, between the teeth and the gums of the user's upper row of teeth; the lower cleaning part is uniformly arranged on the inner walls on both sides of the lower U-shaped groove 112 along the arc direction of the lower U-shaped groove 112, and is used to spray gas or cleaning liquid on the inner and outer sides of the tooth surfaces, between the teeth and the gums of the user's lower row of teeth;

[0053] The conveying component 13 is connected to the cleaning component 12 and is used to convey gas or cleaning liquid to the cleaning component 12; among them,

[0054] The main body 2 is connected to the conveying component 13 of the cleaning head body 1 and is used to provide gas, cleaning liquid and spraying power for the cleaning head body 1.

[0055] Specifically, when cleaning the oral cavity, the user takes the cleaning head body 1, puts the biting part 11 into the oral cavity, puts the upper row of teeth into the upper U-shaped groove 111, and puts the lower row of teeth into the lower U-shaped groove 112. The biting part 11 is fixed by the occlusion of the teeth. Subsequently, the host 2 conveys gas or cleaning liquid to the conveying component 13, and the gas or cleaning liquid is conveyed by the conveying component 13 to the cleaning component 12. The upper cleaning part sprays gas or cleaning liquid onto the inner and outer sides of the tooth surfaces, the gaps between the teeth, and the gums of the upper row of teeth to achieve the cleaning of the upper row of teeth. Similarly, the lower cleaning part sprays gas or cleaning liquid onto the inner and outer sides of the tooth surfaces, the gaps between the teeth, and the gums of the lower row of teeth to achieve the cleaning of the lower row of teeth. In this application, the cleaning component 12 is arranged on the biting part 11. During cleaning, the user fixes the biting part 11 by the occlusion of the teeth, and does not need to hold the cleaning head body 1 for a long time, improving the convenience of the cleaning process. Moreover, the cleaning component 12 of this application uses the methods of gas spraying and liquid spraying to achieve the cleaning of teeth, which can better clean the tooth surfaces and the positions between the teeth, effectively remove plaque on the tooth surfaces, and the cleaning is more comprehensive, avoiding cleaning dead corners. This application can also massage the gum position by spraying, increasing its usage function, and this application is more suitable for orthodontic people, avoiding damage to the dental appliances caused by friction during the cleaning process by traditional toothbrushes with bristles, and increasing its scope of application.

The multiple groups of upper gas nozzle groups one, multiple groups of upper liquid nozzle groups one 121, multiple groups of upper gas nozzle groups two 122, and multiple groups of upper liquid nozzle groups two 123 are all uniformly arranged on the inner walls on both sides of the upper U-shaped groove 111 along the radian direction of the upper U-shaped groove 111. The upper gas nozzle groups one and the upper liquid nozzle groups one 121 are used to spray gas or liquid onto the inner and outer sides of the tooth surfaces and the gaps between the teeth of the upper row of teeth of the user, and the upper gas nozzle groups two 122 and the upper liquid nozzle groups two 123 are used to spray gas or liquid onto the gums of the upper row of teeth of the user;

[0059] The lower cleaning component includes multiple groups of lower gas nozzle groups I, multiple groups of lower liquid nozzle groups I 124, multiple groups of lower gas nozzle groups II, and multiple groups of lower liquid nozzle groups II 125. The multiple groups of lower gas nozzle groups I, multiple groups of lower liquid nozzle groups I 124, multiple groups of lower gas nozzle groups II, and multiple groups of lower liquid nozzle groups II 125 are all uniformly arranged on the inner walls on both sides of the lower U-shaped groove 112 along the arc direction of the lower U-shaped groove 112. The lower gas nozzle group I and the lower liquid nozzle group I 124 are used to spray gas or cleaning liquid towards the inner and outer sides of the tooth surfaces and the tooth gaps of the user's upper row of teeth, and the lower gas nozzle group II and the lower liquid nozzle group II 125 are used to spray gas or cleaning liquid towards the gums of the user's lower row of teeth.

[0060] Specifically, the multiple groups of upper gas nozzle groups I and the multiple groups of upper liquid nozzle groups I 121 are both arranged in a U shape, and the spraying directions are aligned with the inner and outer sides of the upper row of teeth. Moreover, the multiple groups of upper gas nozzle groups I and the multiple groups of upper liquid nozzle groups I 121 are closely arranged, and the upper gas nozzle group I and the upper liquid nozzle group I 121 are arranged alternately, so that they can be aligned with the tooth surfaces and the tooth gap positions for spraying, improving the comprehensiveness of cleaning; and each group of upper gas nozzle groups I includes three gas nozzles arranged vertically. Among the three gas nozzles, the gas nozzle at the uppermost end sprays in an inclined upward direction, the gas nozzle in the middle sprays in a horizontal direction, and the gas nozzle at the lowermost end sprays in an inclined downward direction, realizing multi-angle cleaning and improving the cleaning effect on teeth;

[0061] The multiple groups of upper gas nozzle groups II 122 and the multiple groups of upper liquid nozzle groups II 123 are also both arranged in a U shape, and the spraying directions are aligned with the inner and outer sides of the upper gums. Each group of upper gas nozzle groups II 122 includes a gas nozzle, and the spraying direction of this gas nozzle is towards the upper gums. Each group of upper liquid nozzle groups II 123 includes a liquid nozzle, and the spraying direction of this liquid nozzle is also towards the upper gums. The gas nozzle and the liquid nozzle spray alternately to realize the massage of the upper gums;

[0062] Similarly, the structure of the lower gas nozzle group I in the lower cleaning component is the same as that of the upper gas nozzle group I, and the structure of the lower liquid nozzle group I 124 is the same as that of the upper liquid nozzle group I 121. Each group includes three nozzles with different spraying directions, which are used to spray towards the inner and outer sides of the lower row of teeth to realize the cleaning of the tooth surfaces and the tooth gap positions;

[0063] The lower gas nozzle group two in the lower cleaning component has the same structure as the upper gas nozzle group two 122. Each group includes a gas nozzle, and the jet direction of the gas nozzle is aligned with the lower gum. The lower liquid nozzle group two 125 has the same structure as the lower liquid nozzle group two 124. Each group includes a liquid nozzle, and the jet direction of the liquid nozzle group is also aligned with the lower gum. The gas nozzle and the liquid nozzle are alternately jetted to realize the massage of the lower gum.

[0064] Specifically, upper accommodation grooves 1111 are respectively formed on the inner walls on both sides of the upper U-shaped groove 111 along its arc direction, and the upper cleaning component is installed in the upper accommodation grooves 1111. Lower accommodation grooves are respectively formed on the inner walls on both sides of the lower U-shaped groove 112 along its arc direction, and the lower cleaning component is installed in the lower accommodation grooves, so as to avoid the nozzles from colliding with the teeth, causing discomfort to the teeth, and also avoid damaging the nozzles due to collision.

[0065] In a preferred embodiment, as Figure 3 shown, the conveying assembly 13 includes a first conveying pipe 131, the first conveying pipe 131 is fixedly connected with the grip part 14, and the outlet end of the first conveying pipe 131 is connected in parallel with a first shunt pipe 132, a second shunt pipe 133, a third shunt pipe 134 and a fourth shunt pipe 135. Multiple upper gas nozzle groups one and multiple upper liquid nozzle groups one 121 are both connected with the first shunt pipe 132, multiple upper gas nozzle groups two 122 and multiple upper liquid nozzle groups two 123 are both connected with the second shunt pipe 133, multiple lower gas nozzle groups one and multiple lower liquid nozzle groups one 124 are both connected with the third shunt pipe 134, and multiple lower gas nozzle groups two and multiple lower liquid nozzle groups two 125 are both connected with the fourth shunt pipe 135.

[0066] Specifically, cavities are respectively arranged inside the grip part 14 and the biting part 11, and the first shunt pipe 132, the second shunt pipe 133, the third shunt pipe 134 and the fourth shunt pipe 135 are all installed inside the grip part 14 and the biting part 11, so as to avoid the pipelines from being exposed outside and affecting the user's biting.

[0067] During cleaning, gas or cleaning liquid is conveyed to the upper gas nozzle group one and the upper liquid nozzle group one 121 through the first shunt pipe 132, gas or cleaning liquid is conveyed to the upper gas nozzle group two 122 and the upper liquid nozzle group two 123 through the second shunt pipe 133, gas or cleaning liquid is conveyed to the lower gas nozzle group one and the lower liquid nozzle group one 124 through the third shunt pipe 134, and gas or cleaning liquid is conveyed to the lower gas nozzle group two and the lower liquid nozzle group two 125 through the fourth shunt pipe 135. Hydrophobic membranes are installed on the nozzles of the upper gas nozzle group one, the upper gas nozzle group two 122, the lower gas nozzle group one and the lower gas nozzle group two to avoid the cleaning liquid from spraying out from the gas nozzles; the installation of the hydrophobic membranes is connected by existing achievable connection methods, which will not be elaborated and limited here.

[0068] In a preferred embodiment, as Figure 1 and Figure 3 shown, the cleaning head body 1 further includes a suction assembly 15. The suction assembly 15 includes a Y-shaped tube 151 and a suction pipe 152. The Y-shaped tube 151 includes a main path and a branch path. The main path includes an inlet cylindrical section, a conical contraction section, a cylindrical throat section, and a conical diffusion section connected in sequence. One end of the inlet cylindrical section of the main path is communicated with the outlet end of the first delivery pipe 131. One end of the conical diffusion section of the main path is connected with a drain pipe 153. One end of the branch path is communicated with the cylindrical throat section of the main path, and the other end is communicated with the suction pipe 152. A liquid suction port 154 communicated with the suction pipe 152 is arranged on the inner arc surface of the biting part 11. Gas is used to be conveyed in the main path so as to form a negative pressure in the branch path and discharge the liquid in the user's oral cavity.

[0069] Specifically, the Y-shaped tube 151 adopts a Venturi tube structure, including an inlet cylindrical section, a conical contraction section, a cylindrical throat section, and a conical diffusion section. The inner diameter of the conical contraction section decreases in sequence along the flowing direction of the fluid. The inner diameter of the conical diffusion section increases in sequence along the flowing direction of the fluid. And the inner diameter of the cylindrical throat section is smaller than the minimum inner diameters of the conical contraction section and the conical diffusion section. The cylindrical throat section is the narrowest part of the main pipe.

[0070] When it is necessary to suck the liquid in the oral cavity, the main machine 2 conveys gas with a certain pressure to the first delivery pipe 131. The gas enters the main pipe of the Y-shaped tube 151 and flows. According to the Venturi effect, when the gas passes through the cylindrical throat section, the cross-section decreases, the flow velocity increases, and the pressure decreases, forming a negative pressure at the cylindrical throat section. The branch pipe is connected to the cylindrical throat section, and a negative pressure is also formed in the branch pipe. Under the negative pressure environment, the liquid in the oral cavity flows into the main pipe through the liquid suction port 154 and the suction pipe 152 and is discharged together with the gas. The conical diffusion section of the main pipe is the outlet end of the main pipe. The outlet end is connected with a water collecting box 155 through a drain pipe 143. The liquid in the oral cavity is automatically discharged into the water collecting box 155, avoiding the liquid and impurities generated during oral cleaning from staying in the oral cavity for a long time and realizing the automatic external discharge of the liquid in the oral cavity.

[0071] In a preferred embodiment, as Figure 1 and Figure 3 shown, valves are arranged on the first shunt pipe 132, the second shunt pipe 133, the third shunt pipe 134, the fourth shunt pipe 135, and the inlet cylindrical section of the main path.

[0072] Specifically, the valve is a solenoid valve. The main unit 2 includes a controller, and the valve is electrically connected to the controller. The controller can control the opening or closing of the valve on the corresponding pipeline, so that the corresponding first shunt pipe 132, second shunt pipe 133, third shunt pipe 134, fourth shunt pipe 135 and Y-shaped pipe 151 are in a conductive state or a non-conductive state, realizing the control of the cleaning of the corresponding positions of the teeth. For example, cleaning the tooth surfaces and interdental spaces of the upper row of teeth alone, cleaning the tooth surfaces and interdental spaces of the lower row of teeth alone, cleaning the upper and lower rows of teeth at the same time, massaging the upper gums alone, massaging the lower gums alone, massaging the upper and lower gums at the same time, etc.

[0073] In a preferred embodiment, as Figure 1 and Figure 9 shown, the main unit 2 includes a main unit housing 21, a second delivery pipe 24, a third delivery pipe 25, a fourth delivery pipe 22, a gas supply mechanism for supplying gas and a liquid supply mechanism 22 for supplying cleaning liquid. The gas supply mechanism and the liquid supply mechanism 22 are both arranged inside the main unit housing 21. The inlet end of the second delivery pipe 24 is connected to the gas supply mechanism and the liquid supply mechanism 22. The inlet end of the third delivery pipe 25 is connected to the gas supply mechanism. The inlet end of the fourth delivery pipe 23 is connected to the outlet pipes of the second delivery pipe 24 and the third delivery pipe 25. The outlet end of the fourth delivery pipe 23 is detachably connected to the inlet end of the first delivery pipe 131 through a mounting assembly 3.

[0074] Preferably, a controller is also arranged inside the main unit housing 21, and a control panel 26 is arranged on the outer wall of the main unit housing 21. The gas supply mechanism, the liquid supply mechanism 22, the control panel 26 and the valve are all electrically connected to the controller.

[0075] Specifically, the cleaning head body 1 can be disassembled through the mounting assembly 3. There are various models of the cleaning head body 1, which are suitable for adults and children. Users can replace the cleaning head body 1 according to their own usage needs;

[0085] Working principle:

[0086] When cleaning teeth, the user selects a suitable cleaning head type according to his or her own needs. The user takes the cleaning head body 1 through the grip 14, puts the bite portion 11 into the oral cavity, and fixes the bite portion 11 by biting the teeth. It is not necessary to hold the teeth for a long time, which improves the convenience of cleaning. Then, the user selects the required cleaning mode by operating the control panel 26, and the controller controls the corresponding valve to open to realize the separate delivery of gas, clean water or liquid toothpaste. Then, in the corresponding mode, the first shunt pipe 132, the second shunt pipe 133, and the third shunt pipe 13 4 and the corresponding valves on the fourth shunt pipe 135 are opened to realize gas injection or liquid injection, thereby realizing oral cleaning in the corresponding mode. During the cleaning process, the controller can also control the valve on the Y-tube 151 and the valve on the third delivery pipe 25 to open, and the gas supply mechanism provides gas with a certain pressure. The gas flows in the main path of the Y-tube 151, so that negative pressure is formed in the branch path. The liquid generated in the oral cavity flows into the main path through the liquid suction port 154 and the suction pipe 152, and is discharged into the water collection box 155 together with the gas, completing the automatic discharge of the liquid and realizing the cleaning of the teeth;

[0087] The cleaning component 12 of the present application uses gas injection and liquid injection to clean the teeth, which can better clean the tooth surface and the gaps between teeth, effectively remove dental plaque on the tooth surface, clean more comprehensively, and avoid cleaning dead corners. The present application can also massage the gum position by injection to increase its usage function, and the present application is more suitable for orthodontic people, avoiding damage to braces caused by friction during the cleaning process of traditional toothbrushes with bristles, thereby increasing its scope of application.
