[0026] The purpose of this invention is to provide a toothbrush and a water flosser to solve the problem in the prior art that food residue cannot be effectively cleaned while wearing braces.

[0027] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0028] See Figure 1 This application provides a toothbrush, including a handle 1, a nozzle 2, and a brush head 3.

[0029] The brush handle 1 has a water channel 12 for connecting to the water supply end.

[0030] The nozzle 2 is connected to the end of the brush handle 1 away from the water supply end. The inside of the nozzle 2 is connected to the water channel 12, and a rotating component 21 is provided inside the nozzle 2.

[0031] One end of the brush head 3 passes through the nozzle 2 and is connected to the rotating component 21. The other end of the brush head 3 is provided with multiple bristles 31, which are distributed in an umbrella shape.

[0032] The water flow from the water supply end into the brush handle 1 flows through the water channel 12 to the nozzle 2, which drives the rotating part 21 to rotate and drives the brush head 3 to rotate.

[0033] This embodiment of the application achieves thorough cleaning of teeth by providing multiple bristles 31 arranged in an umbrella shape at the other end of the brush head 3. On the one hand, when the water flow drives the rotating component to rotate and thus drives the brush head to rotate, the umbrella shape of the bristles 31 can increase the coverage area of ​​the bristles 31, thereby improving the cleaning effect of the teeth. On the other hand, the water flow can flow along the bristles 31 to all places, which also increases the water coverage area and improves the rinsing effect, further improving the cleaning effect. At the same time, compared with the prior art, the toothbrush provided by this embodiment can still effectively clean teeth without changing the grip angle of the toothbrush in real time, thus improving the user experience.

[0034] Combination Figure 1 See Figure 2 In one embodiment, the nozzle 2 includes a mounting part 24 with a mounting hole. The mounting part 24 is sleeved on the brush handle 1 through the mounting hole to fix the nozzle 2 to the brush handle 1.

[0035] Specifically, a spiral part can be provided on the side of the brush handle 1 near the nozzle 2. The spiral part is threaded and the mounting hole is a threaded hole. The brush handle 1 is connected to the nozzle 2 by screwing the spiral part into the mounting hole.

[0036] In one embodiment, the brush head 3 can be integrally injection molded from TPU and detachably connected to the rotating component 21 for easy replacement, adaptability to different cleaning needs, flexibility, and improved user experience.

[0037] In one embodiment, the bristles 31 are positioned away from the end of the nozzle 2 and extend in a direction away from the central axis of the brush head 3 to maximize the coverage area of ​​the bristles 31 on the teeth.

[0038] In one embodiment, a water nozzle 4 is provided on the side of the nozzle 2 near the brush head 3. The water nozzle 4 is connected to the water channel 12 and is provided corresponding to the brush head 3. The water flow in the nozzle 2 is sprayed out from the water nozzle 4 and sprayed along the bristles 31.

[0039] In this embodiment, the water nozzle 4 is configured to face the rotating brush head 3, the tooth surface, and the orthodontic appliance. When the brush head 3 rotates to clean food debris in the gaps between teeth and the gaps in the orthodontic appliance, the water jet from the nozzle 4 can wash the tooth surface and the orthodontic appliance surface and remove food debris. Furthermore, by setting the rotating brush head 3 to drive the bristles 31 to rotate continuously to clean the teeth, the water jet from the nozzle 4 can also wash and clean the tooth surface, the gaps between teeth, the orthodontic fixing blocks, and the gaps in the archwire, thereby improving the cleaning effect of the toothbrush.

[0040] Combination Figure 1 See Figure 3In one embodiment, the waterway 12 has a guide hole 121 and a spray nozzle 4 is provided, wherein there is a distance between the spray nozzle 4 and the guide hole of the waterway 12.

[0041] In one embodiment, the diameter of the water nozzle 4 is R, wherein 1.5≤R≤2.5mm, and there is a distance L between the water nozzle 4 and the guide hole 121 of the water channel 12, wherein 5mm≤L≤8mm.

[0042] In this embodiment, the distance between the guide hole 121 and the spray nozzle 4 is adjusted to adjust the pressure difference of the water flow, thereby adjusting the rotational power obtained by the rotating component 21 to adapt to different cleaning needs and improve the user experience.

[0043] In another embodiment, multiple water nozzles 4 are provided, and the multiple water nozzles 4 are concentrated on the surface of the nozzle 2 and located within the projection area of ​​the bristles 31.

[0044] In one embodiment, the diameters of the plurality of water nozzles 4 are R, wherein 1.5≤R≤2.5mm.

[0045] This application features multiple water nozzles 4 to increase water output and further enhance cleaning effectiveness. Simultaneously, concentrating these nozzles within the projection area of ​​the bristles 31 allows the high-speed rotating bristles 31 to propel water towards the sides of the tooth surface, creating a lateral impact force. This further improves the cleaning effect on the sides of the teeth.

[0046] In one embodiment, the nozzle 2 has a receiving cavity 22 and a guide groove 25 that communicate with the spray nozzle 4. The guide groove 25 is located on the side of the receiving cavity 22. The rotating component 21 is disposed in the receiving cavity 22, and the guide groove 25 is connected to the receiving cavity 22 and the water channel 12, that is, the guide groove 25 is connected to the guide hole 121.

[0047] Correspondingly, the nozzle 2 has a water outlet 26, which is connected to the guide hole 121. The water flowing out of the guide hole 121 enters the guide groove 25 through the water outlet 26.

[0048] Water flowing out of the above-mentioned guide hole 121 flows into the guide groove 25 through the outlet 26, and then flows into the receiving cavity 22 along the guide groove 25. After driving the rotating component 21 to rotate, it finally flows out from the spray nozzle 4.

[0049] In one embodiment, the central axis of the waterway 12 intersects with and is perpendicular to the axis of rotation of the rotating component 21 about the first axis.

[0050] The axis of the first axis is the central axis of the rotating component 21.

[0051] In the toothbrush nozzle 2 provided in this embodiment, by setting the central axis of the water channel 12 and the axis of the first axis of rotation of the rotating component 21 to intersect and be perpendicular, the rotating component 21 and the guide hole 121 are on the same horizontal line. While ensuring the aesthetic appearance, the water flow can be guided to the edge of the rotating component 21 by cooperating with the setting of the guide groove 25 to impact the rotating component 21, so as to provide the rotation direction of the rotating component 21 and sufficient torque, improve the rotation accuracy of the rotating component 21, ensure the rotation effect of the rotating component 21, and thus improve the cleaning effect.

[0052] The aforementioned receiving cavity 22 is connected to the water nozzle 4. By setting the receiving cavity 22 and combining it with the water nozzle 4, the water flowing out of the water channel 12 of the brush handle 1 forms a pressure difference in the nozzle 2, and the rotating component 21 is driven by the pressure difference to obtain rotational power.

[0053] The embodiments of this application can control the pressure difference by adjusting the orifice size of the rotating component 21 and the nozzle 4 to adapt to different cleaning needs, thus providing a certain degree of flexibility.

[0054] See Figure 4-5 In one embodiment, the nozzle 2 has a connecting hole 23 that communicates with the receiving cavity 22, and one end of the brush head passes through the connecting hole 23 and is connected to the rotating component 21.

[0055] The nozzle 2 includes a nozzle cover 27, which covers the aforementioned receiving cavity 22 to seal the receiving cavity 22.

[0056] In one embodiment, the brush head 3 includes a fixing post 32, which is entirely disposed inside the nozzle 2. The end face of the fixing post 32 away from the rotating component 21 is disposed at the connection hole 23 and is at the same level as the outer surface of the nozzle 2 (not shown in the figure). The bristles 31 are connected to the end face of the fixing post 32 away from the rotating component 21.

[0057] In another embodiment, such as Figure 4-5 As shown, the brush head 3 includes a fixing post 32. One end of the fixing post 32 is disposed inside the nozzle 2 and connected to the rotating component 21. The other end of the fixing post 32 passes through the connecting hole 23 and at least partially extends out of the nozzle 2. The bristles 31 are connected to the end face and side face of the fixing post 32 away from the inside of the nozzle 2.

[0058] In one embodiment, the rotating component 21 has a fixing hole 211, and the brush head 3 is provided with a connecting part 33 at one end near the rotating component 21. That is, the connecting part 33 is provided at one end of the fixing post 32 near the rotating component 21. The connecting part 33 is engaged in the fixing hole 211, and the rotating component 21 can rotate around the connecting part 33 so that the brush head 3 can be detachably connected to the rotating component 21.

[0059] In one embodiment, the rotating component 21 can be an impeller rotor structure, a vane rotor structure, or a double gear structure, etc.

[0060] This application embodiment also provides a water flosser, including the toothbrush and water supply end provided in the above embodiment. The water supply end is connected to the water channel 12 in the brush handle 1 and is used to supply water to the toothbrush.

[0061] When the water flosser provided in this embodiment is working, the high-pressure water jet enters from the tail of the brush handle 1—that is, from the end of the brush handle 1 away from the nozzle 2—and flows into the receiving cavity 22 of the nozzle 2 along the water channel 12. The high-pressure water jet drives the rotating component 21 inside the nozzle 2 to rotate, and after rotating for a preset distance or preset time, it sprays out from the water nozzle 4 to release pressure. It uses the water pressure difference to drive the rotating component 21 to obtain rotational power, and also removes food residue by rinsing the tooth surface, thus having a flexible and efficient cleaning effect.
