[0057] Combination Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides an electric toothbrush including a brush head assembly 10 , a handle 20 and a base 30 . The brush head assembly 10 comprises a rolling brush 11 and a flushing part 12; the handle 20, the brush head assembly 10 is detachably connected to the handle 20, wherein the handle 20 comprises a driving assembly 21, a liquid storage assembly 22 and a battery assembly 23, the driving end 211 of the driving assembly 21 is drivingly connected to the rolling brush 11, and the liquid outlet end 223 of the liquid storage assembly 22 is connected to the flushing part 12; the base 30, which has a liquid storage space 31 in its interior and a receiving groove 32 in its exterior, a liquid supply port 321 connected to the liquid storage space 31 is arranged in the receiving groove 32, and a charging assembly 33 is arranged on the groove wall of the receiving groove 32; wherein the handle 20 can be inserted into the receiving groove 32, so that the liquid inlet end 224 of the liquid storage assembly 22 is connected to the liquid supply port 321, so as to supply liquid to the liquid storage assembly 22, and the charging assembly 33 is connected to the battery assembly 23, so as to charge the battery assembly 23.

[0058] The electric toothbrush provided by the embodiment of the present disclosure has a brush head assembly 10 having a rolling brush 11 and a rinsing portion 12, wherein the rolling brush 12 is drivingly connected to the driving end 211 of the driving assembly 21 in the handle 20, so that the rolling brush 12 can be driven to clean the teeth; the rinsing portion 12 is connected to the liquid outlet end 223 of the liquid storage assembly 22 in the handle 20, so that the rinsing portion 12 can spray cleaning liquid to clean the teeth; in this way, the rolling brush 11 and the rinsing portion 12 can clean the teeth at the same time, so that the overall cleaning effect is better; in addition, the handle 20 can also be set on the receiving groove 32 of the base 30, and a liquid supply port 321 connected to the liquid storage space 31 is provided in the receiving groove 32, and a charging assembly 33 is provided on the groove wall of the receiving groove 32, and the liquid inlet end 224 of the liquid storage assembly 22 is connected to the liquid supply port 321, and the charging assembly 33 is connected to the battery assembly 23, so that the battery assembly 23 can be charged and the liquid storage assembly 22 can be supplemented with cleaning liquid, so as to facilitate user use.

[0059] In the disclosed embodiment, the rolling brush 11 includes a rolling shaft and a plurality of bristles arranged on the rolling shaft, and the bristles radiate outward around the rotation direction of the rolling shaft. Here, the bristles are flexible bristles, and are relatively short in length, and the outer ends of the bristles have a high roundness. The roundness refers to the roundness of a single bristle when the outer end of the bristle contacts and rubs against the teeth. The higher the roundness, the less wear on the teeth.

[0060] In the disclosed embodiment, the length of the bristles ranges from [5 mm, 7 mm]. Optionally, the length of the bristles is 5 mm. Optionally, the length of the bristles is 6 mm. Optionally, the length of the bristles is 7 mm. This is not limited here.

[0061] In the disclosed embodiment, the diameter size of the rolling brush 11 ranges from [15mm, 20mm]. Optionally, the diameter size of the rolling brush 11 is 15mm. Optionally, the diameter size of the rolling brush 11 is 16mm. Optionally, the diameter size of the rolling brush 11 is 17mm. Optionally, the diameter size of the rolling brush 11 is 18mm. Optionally, the diameter size of the rolling brush 11 is 19mm. Optionally, the diameter size of the rolling brush 11 is 20mm. Not limited here.

[0062] In the disclosed embodiment, the material of the bristles may include one or more combinations of polyethylene glycol terephthalate (PET), polyethylene terephthalate (PBT), polyamide (PA) and carbon fiber. Here, polyethylene terephthalate has the characteristics of high softness, high toughness, low water absorption, etc., so the tip of the bristle is thinner and can more effectively penetrate into the gingival sulcus to remove dental plaque. Carbon fiber material has high strength and rigidity and can withstand greater pressure and bending. Here, the bristles can be fixed on the rolling shaft by traditional hair planting.

[0063] In the disclosed embodiment, the rolling brush 11 may be a short cylinder. When in use, the rolling brush 11 will extend along the gums, and the multiple bristles of the rolling brush 11 will continuously clean the teeth and remove the residues in the gaps between the teeth. Compared with the vibration cleaning method, the cleaning effect is better.

[0064] In the disclosed embodiment, the driving component 21 may be a motor, and the driving end 211 of the driving component 21 may drive the rolling brush 11 to rotate clockwise or counterclockwise. For example, when cleaning the upper right teeth, the bristles are moved from the root of the teeth to the tip of the teeth along the direction in which the gums extend, and the rolling brush 11 needs to rotate clockwise; when cleaning the lower right teeth, the bristles are moved from the root of the teeth to the tip of the teeth along the direction in which the gums extend, and the rolling brush 11 needs to rotate counterclockwise; therefore, when the rolling brush 11 cleans teeth at different positions, rotating the rolling brush 11 in different directions can improve the cleaning effect.

[0065] Combination Fig. 9 As shown, in some embodiments, the flushing portion 12 includes a flushing cavity 121 and a flushing port 122 disposed on the flushing cavity 121; wherein, one or more valves 123 are disposed in the flushing cavity 121, so that the flushing cavity 121 forms two or more pressurized cavities 124, and a spray port 1231 that can be elastically opened and closed is disposed in the middle of each valve 123.

[0066] In the disclosed embodiment, a spray port 1231 that can be opened and closed elastically is provided in the middle of the valve 123. In this way, by using the multi-layer valve 123 in combination, a plurality of liquid storage chambers are separated, so that the flushing part 12 can have a certain spray force and strength, and save the cleaning liquid.

[0067] Optionally, the flushing portion 12 includes a valve 123, thereby separating the flushing chamber 121 into two pressurizing chambers 124, namely a first pressurizing chamber and a second pressurizing chamber. Here, the cleaning liquid passes through the first pressurizing chamber and the second pressurizing chamber in sequence, and the caliber of the flushing port 122 located in the flushing chamber 121 is larger than the caliber of the injection port 1231 of the valve 123.

[0068] When the flushing part 12 sprays the cleaning liquid, the cleaning liquid will first enter the first pressurized chamber, and then enter the second pressurized chamber; at this time, the pressure in the second pressurized chamber increases, which will force part of the cleaning liquid to be squeezed back into the first pressurized chamber, and part of the cleaning liquid will be sprayed out from the flushing port 122 of the flushing chamber 121; in this process, the diameter of the spraying port 1231 of the valve 123 gradually decreases until it is closed. In this way, repeated cycles can form a pulsed water flow, and the flushing part 12 can have a certain spray force and strength, and save cleaning liquid.

[0069] Combination Figures 6 to 8 As shown, in some embodiments, the brush head assembly 10 also includes: a base 13, which is detachably connected to the handle 20; a mounting plate 14, which is arranged on the base 13, and the end of the mounting plate 14 is constructed with a rolling brush shielding area 141, wherein the rolling brush 11 and the flushing part 12 are located in the rolling brush shielding area 141, and a pipeline connecting the liquid storage assembly 22 and the flushing part 12 is formed in the base 13 and the mounting plate 14; a rolling shaft 15, a first end of which passes through the bottom of the base 13 and is connected to the driving end 211 of the driving assembly 21, and a second end of which is rotatably arranged in the rolling brush shielding area 141 and is connected to the rolling brush 11.

[0070] Among them, enclosing baffles 142 are arranged on both sides of the rolling brush shielding area 141; wherein, the flushing part 12 is arranged on the rolling brush shielding area 141, the flushing direction of the flushing part 12 is toward the rolling shaft rod 15 side, and the rolling brush 11 avoids the flushing direction of the flushing part 12.

[0071] In the disclosed embodiment, the base 13 can be mounted on the handle 20 by means of snap-on or screw-on. A mounting plate 14 is provided on the base 13, and a rolling brush shielding area 141 is configured at the end of the mounting plate 14. The first end of the rolling shaft 15 passes through the bottom of the base 13 and is connected to the driving end 211 of the driving assembly 21. The first end of the rolling shaft 15 is a connecting shaft; the second end of the rolling shaft 15 is rotatably disposed in the rolling brush shielding area 141 and is connected to the rolling brush 11. Here, the rolling brush 11 is a short cylindrical shape, and is connected to the driving end 211 of the driving assembly 21 through the rolling shaft 15. A mounting hole is provided at the axis position of the driving end 211, and the cross section of the mounting hole is rectangular. The cross section of the second end of the rolling shaft 15 is rectangular, and can extend into the mounting hole, so that the driving end 211 can rotate with the rolling shaft 15, thereby driving the rolling brush 11 to rotate.

[0072] Optionally, the cross-section of the mounting hole can also be rectangular, diamond-shaped or other shapes besides circular. When driving the rolling shaft 15 to rotate, the possibility of relative sliding between the driving end 211 and the rolling shaft 15 can be reduced, which is beneficial to improving the stability of the rolling brush 11.

[0073] In the embodiment of the present disclosure, the rolling brush shielding area 141 set on one side of the rolling brush 11 can prevent the rolling brush 11 from detaching from the rolling shaft 15, and can also separate the rolling brush 11 from the oral mucosa. The side of the rolling brush shielding area 141 away from the rolling brush 11 is a smooth surface, which can reduce the wear of the rolling brush 11 on the oral mucosa during brushing.

[0074] In the disclosed embodiment, the flushing portion 12 is located in the rolling brush shielding area 141, and a pipeline connecting the liquid storage component 22 and the flushing portion 12 is formed in the base 13 and the mounting plate 14. In this way, the flushing portion 12 can be continuously supplied with liquid through the pipeline. The pipeline and the liquid storage component 22 are also detachably connected, and a sealing structure is provided at the connection to ensure the sealing of the connection.

[0075] In the disclosed embodiment, enclosing baffles 142 are provided on both sides of the rolling brush shielding area 141, which can not only block the water thrown out when the rolling brush 11 rotates, but also isolate the rolling brush 11 from the oral mucosa. Here, the rolling brush shielding area 141 is an arc-shaped surface, and the rolling brush shielding area 141 needs to shield part of the rolling brush 11. However, the rolling brush 11 will not be completely shielded. If the arc length of the rolling brush shielding area 141 is too long, when the rolling brush 11 cleans the teeth, it will interfere with the teeth or gums, affecting the cleaning effect of the bristles 33 on the teeth.

[0087] In the disclosed embodiment, the liquid storage tank 221 is used to store the cleaning liquid, wherein a piston 222 is provided in the liquid storage tank 221, and the liquid level of the cleaning liquid in the liquid storage tank 221 is controlled by the piston 222. Here, the liquid storage tank 221 is connected with a liquid outlet 223 and a liquid inlet 224. The liquid inlet 224 is connected to the liquid supply port 321 of the base 30. The liquid outlet 223 is connected to the pipeline of the flushing part 12.

[0088] Optionally, when it is necessary to add cleaning fluid to the liquid storage tank 221, the piston 222 moves from the top of the liquid storage tank 221 to the bottom of the liquid storage tank 221, so that the air pressure in the liquid storage tank 221 changes, allowing the cleaning fluid to enter the liquid storage tank 221 from the liquid storage space 31.

[0089] Optionally, when the cleaning liquid is transported from the liquid storage tank 221 to the flushing part 12, the piston 222 moves from the bottom of the liquid storage tank 221 to the top of the liquid storage tank 221, so that the cleaning liquid in the liquid storage tank 221 is squeezed to the liquid outlet end 223, and the cleaning liquid in the liquid storage tank 221 can flow from the liquid outlet end 223 into the flushing part 12.

[0090] In the embodiment of the present disclosure, a hollow shaft motor 225 is provided below the liquid storage tank 221, and the hollow shaft motor 225 includes a hollow shaft 226 and a rotating shaft 227. The hollow shaft 226 is a hollow structure, and the hollow shaft motor 225 can control the movement of the hollow shaft 226. In this way, the rotating shaft 227 can move telescopically in the hollow shaft 226. In this way, the rotating shaft 227 can move telescopically in the hollow shaft 226, thereby greatly shortening the distance between the liquid storage tank 221 and the hollow shaft motor 225, thereby reducing the space occupied by the liquid storage assembly 22, thereby reducing the size of the handle 20.

[0091] Here, when the rotating shaft 227 does not extend from the hollow shaft 226, the piston 222 is located at the bottom of the liquid storage tank 221. When a portion of the shaft of the rotating shaft 227 extends from the hollow shaft 226, the piston 222 moves from the bottom of the liquid storage tank 221 to the top of the liquid storage tank 221. In this way, the piston 222 can be controlled to reciprocate by the rotating shaft 227.

[0092] Optionally, in some embodiments, the hollow shaft 226 is connected to a part of the shaft rod or the entire shaft rod of the rotating shaft 227 by threads. In this way, the rotating shaft 227 can be telescopically moved in the hollow shaft 226.

The length of the rotating shaft 227 is less than or equal to the length of the hollow shaft 226, and the length of the rotating shaft 227 is greater than or equal to the depth of the liquid storage tank 221. Here, in the case where a part of the shaft of the rotating shaft 22 is provided with an external thread, the part of the shaft is the end of the rotating shaft 22 away from the piston 222.

[0094] Optionally, in some embodiments, the end of the rotating shaft 227 and the piston 222 are integrally structured, which can ensure that the rotating shaft 227 and the piston 222 have a certain strength.

[0095] In the disclosed embodiment, the amount of cleaning liquid in the liquid storage tank 221 can be controlled by the piston 222, but the liquid level of the cleaning liquid in the liquid storage tank 221 cannot be accurately determined. Therefore, a sensor assembly 228 is also provided on the liquid storage tank 221.

Here, when the sensor assembly 228 detects that the liquid level is low, the hollow shaft 226 of the hollow shaft motor 225 rotates counterclockwise; when the sensor assembly 228 detects that the liquid level reaches the set high liquid level, the hollow shaft motor 225 stops running.

[0098] In the embodiment of the present disclosure, for example, when the liquid storage tank 221 is squeezing out the cleaning liquid, the hollow shaft 226 of the hollow shaft motor 225 needs to rotate clockwise, so that the piston 222 can be prevented from hitting the top of the liquid storage tank 221 while the hollow shaft motor 225 is still running.

[0135] In the implementation of the present disclosure, in order to facilitate the use of the user, the height and width of the electric toothbrush are subject to certain size restrictions, so that it is convenient for the user to pick up the electric toothbrush. Among them, the height and width dimensions of most electric toothbrushes differ greatly, so it is not easy for the electric toothbrush to stand on a horizontal plane. Similarly, when the electric toothbrush is charged, its stability must also be ensured. Therefore, a liquid supply port 321 is provided in the receiving groove 32, and a charging component 23 is also provided on the groove wall side of the receiving groove 32. Among them, the positioning column 35 and the second positioning adsorbent 351 can ensure that the receiving coil 234 of the battery assembly 23 accurately matches the charging coil 331 of the charging assembly 23, and the liquid inlet end 223 on the liquid storage assembly 22 accurately matches the liquid supply port 321.

[0136] In the embodiment of the present disclosure, the positioning column 35 is a column, and a groove is provided on the handle 20. When the handle 20 is inserted into the receiving groove 32, the groove of the handle 20 is also inserted into the positioning column 35. At the same time, the liquid inlet end 223 and the liquid supply port 321 can also be connected to each other, so as to ensure that the handle 20 will not shake or rotate in the receiving groove 32.

[0137] Here, when the positioning column 35 is used in conjunction with the liquid supply port 321, it can ensure that the electric toothbrush can only be fixed in the receiving groove 32 in one direction or one position, thereby avoiding the situation where the electric toothbrush is not placed accurately.

[0138] On this basis, a second positioning adsorption member 351 is further provided in the support boss 34, and a first positioning adsorption member 235 is provided in the handle 20. In this way, through the mutual attraction between the first positioning adsorption member 235 and the second positioning adsorption member 351, it is possible to ensure that the charging coil 331 of the charging assembly 33 matches the receiving coil 234 of the battery assembly 23, and the liquid inlet end 223 on the liquid storage assembly 22 accurately matches the liquid supply port 321. This can further ensure the stability of the handle 20 in the receiving groove 32. Optionally, the first positioning adsorption member 235 and the second positioning adsorption member 351 are magnets, and two are provided; wherein, on the handle 20 side, the two magnets are respectively provided on both sides of the receiving coil 234 in the handle 20. On the support boss 34 side, the two magnets are respectively provided on both sides of the charging coil 71 in the support boss 34.

[0139] Combination Figures 19 to 23 As shown, in some embodiments, the base 30 also includes: a second observation window 38, which is arranged on the outer wall of the base 30, for observing the liquid level in the liquid storage space 31; and / or, a drainage channel 39, wherein the water inlet of the drainage channel 39 is arranged in the receiving groove 32, and the water outlet of the drainage channel 39 is arranged at the bottom of the base 30; when the base 30 includes the drainage channel 39, the base 20 also includes a gasket 36, and the gasket 36 is arranged at the bottom of the base 30.

[0140] In the disclosed embodiment, after using the electric toothbrush, water or foam will remain on the handle 20, and putting it into the receiving groove 32 may cause the water to remain in the receiving groove 32. Therefore, a water inlet of the drainage channel 39 is provided on the side of the receiving groove 32, so that the water in the receiving groove 32 can enter the drainage channel 39 through the water inlet; and a water outlet of the drainage channel 39 is provided at the bottom of the base 30, so that the water in the drainage channel 39 can flow out from the bottom of the base 30 to discharge the water in the receiving groove 32.

[0141] In the embodiment of the present disclosure, in order to quickly drain the water in the receiving tank 32, the drainage channel 39 is a vertical channel and runs through the base 30 itself. In this way, the water can flow directly out of the drainage channel 39. In addition, the water inlet of the drainage channel 39 is an arc-shaped concave structure, which can also make the water in the receiving tank 32 gather to the water inlet of the drainage channel 39.

[0142] In the disclosed embodiment, the liquid level in the liquid storage space 31 can be observed through the second observation window 38, so as to determine whether it is necessary to add cleaning liquid to the liquid storage space 31. Here, a corresponding liquid level mark is provided on the second observation window 38 to remind the user of the actual cleaning liquid capacity in the liquid storage space 31.

[0143] In the embodiment of the present disclosure, the outer surface of the gasket 36 is provided with a texture, so that it can have a certain anti-slip performance and ensure the stability of the base. In addition, the gasket 36 can make a certain distance between the base 30 and the placement plane, so that the water in the drainage channel 39 flows out from the bottom of the base 30. At the same time, one or more drainage grooves 361 are also provided on the gasket 36, so that the water at the bottom of the base 30 can flow out from the drainage grooves 361, so that the user can clean it.

[0144] Whether replenishing the cleaning liquid for the base 30, replenishing the cleaning liquid for the handle 20, or spraying the cleaning liquid from the flushing portion 12, it is necessary to ensure that the cleaning liquid cannot flow back. Figures 2 to 5 , Fig.18 and Fig.21 As shown, in some embodiments, a one-way valve assembly 40 is respectively provided on the liquid inlet pipeline 2241 , the liquid outlet pipeline and the liquid injection port 311 ; the one-way valve assembly 40 can realize one-way flow of the cleaning liquid.

[0145] The one-way valve assembly 20 includes a valve body 21, an elastic member 23 and a valve core 24. A valve channel 22 having a narrowed opening on one side and a widened opening on the other side is constructed inside the valve body 21. The narrowed opening is the liquid inlet of the valve channel 22, and the widened opening is the liquid outlet of the valve channel 22. The elastic member 23 is arranged in the valve channel 22, and one end of the elastic member 23 abuts against the widened side of the valve channel 22. The valve core 24 is arranged in the valve channel 22, and the valve core 24 abuts against the other end of the elastic member 23. In this way, the elastic force of the elastic member 23 can make the valve core 24 abut against the narrowed opening of the valve channel 22 to realize the circulation of liquid.

[0146] In the embodiment of the present disclosure, when the one-way valve assembly 20 is in a blocking state, the elastic force of the elastic member 23 can make the valve core 24 always block the constriction of the valve channel 22 to achieve the blocking function. When the one-way valve assembly 20 is in a conducting state, the valve core 24 is squeezed by liquid, forcing the valve core 24 to squeeze the elastic member 23 to deform, so that the valve core 24 leaves the constriction of the valve channel 22, and the liquid enters the valve channel 22 from the constriction to achieve the conducting function.

[0147] In the embodiment of the present disclosure, Figure 2 and Figure 4 As shown, when the one-way valve assembly 40 is arranged in the liquid inlet pipeline 2241 (liquid inlet end 224), the constricted side of the valve channel 42 faces the liquid storage space 31. In this way, the cleaning liquid on the side of the liquid storage space 31 can push the valve core 44 to leave the constricted side of the valve channel 42, so that the cleaning liquid enters the liquid inlet pipeline 2241, thereby realizing the conduction function.

[0148] In the embodiment of the present disclosure, Figure 2 , Figure 3 and Fig.18 As shown, when the one-way valve assembly 40 is arranged on the liquid outlet pipeline (liquid outlet end 223), the constricted side of the valve channel 42 faces the liquid storage tank 221. In this way, only the cleaning liquid on the side of the liquid storage tank 221 can push the valve core 44 to leave the constricted side of the valve channel 42, so that the cleaning liquid enters the liquid outlet pipeline, thereby realizing the conduction function.

[0149] In the embodiment of the present disclosure, Figure 2 , Figure 4 and Fig.21 As shown, when the one-way valve assembly 40 is arranged at the liquid supply port 321, the constricted side of the valve channel 42 faces the liquid storage space 31. In this way, only the cleaning liquid from the side away from the liquid storage tank 221 can push the valve core 44 to leave the constricted side of the valve channel 42, so that the cleaning liquid passes through the liquid supply port 321 and enters the liquid inlet end 224, thereby realizing the conduction function.

[0150] In the embodiment of the present disclosure, Figure 2 , Figure 5 and Fig.21 As shown, when the one-way valve assembly 40 is arranged at the liquid injection port 311, the constricted side of the valve channel 42 is away from the liquid storage space 31. In this way, only the cleaning liquid from the side away from the liquid storage tank 221 can push the valve core 44 to leave the constricted side of the valve channel 42, so that the cleaning liquid enters the liquid storage space 31 through the liquid injection port 311, thereby realizing the conduction function.
