[0044] See also Figure 1-Figure 7 The present application provides an oral cleaning device 10, which may be an electric toothbrush or a tooth cleaner. The oral cleaning device 10 includes a housing 4, the housing 4 having an outlet 41, and a toothbrush head may be disposed at the outlet 41 of the housing 4.

[0045] Specifically, a driving device is arranged in the shell 4, and the driving device includes a fluid transmission member 1 and a first driving member 2. The first driving member 2 includes a first driving body 21 and a first driving shaft 22. The first driving shaft 22 is arranged on the first driving body 21 to form a first output end 221 at one end of the first driving body 21. The first output end 221 is used to output power to an external device, such as a toothbrush head. The movement of the first output end 221 includes rotation, swinging, telescopic, etc. A second output end 222 is formed at the other end of the first driving body 21. The movement of the second output end 222 includes rotation, swinging, telescopic, etc. The second output end 222 is connected to the fluid transmission member 1 to drive the fluid transmission member 1 to transmit fluid.

[0046] In this embodiment, the first driving member 2 and the fluid conveying member 1 are combined together, and the first output end 221 of the first driving shaft 22 is used to output power to an external device, and the second output end 222 of the first driving shaft 22 is used to promote the fluid conveying member 1 to achieve the fluid conveying function. In summary, the driving device in this embodiment not only meets the requirements of outputting rotational force and promoting fluid conveying, but also reduces the space occupied by the first driving member 2 and the fluid conveying member 1, thereby reducing the volume of the oral cleaning device 10.

[0047] In this example, see Figure 2 The driving device further comprises a second driving member 3, the second driving member 3 has a hollow passage 31, and the fluid transmission member 1 is connected to the hollow passage 31. In this embodiment, the hollow passage is provided through the outlet end 41 of the housing 4 to guide the fluid of the fluid transmission member 1. It can be understood that the fluid can be gas or water.

[0048] Specifically, the input port of the fluid transmission member 1 is provided with a fluid input pipe 11, and the output port of the fluid transmission member 1 is provided with a fluid output pipe 13, and the other end of the fluid output pipe 13 is connected to the hollow channel 31 to guide the fluid to the hollow channel 31. In this embodiment, the second output end 222 of the first drive shaft 22 drives the fluid transmission member 1 to drive the transmission of the fluid, so that the fluid flows in along the fluid input pipe 11, and after being pumped by the fluid transmission member 1, the fluid is promoted to flow to the fluid output pipe 13, thereby entering the hollow channel 31 and staying at the brush head (not shown). It can be understood that in this embodiment, when the fluid is water, the fluid transmission member 1 is a water pump, and when the fluid is gas, the fluid transmission member 1 is an air pump.

[0049] See also Figure 7-Figure 8 The fluid transmission member 1 in this embodiment includes a housing 18, a triggering part 17 and a transmission part 12 disposed in the housing 18, and the second output end 222 is connected to the triggering part 17 to drive the triggering part 17 to move, thereby triggering the transmission part 12 to transmit the fluid flow. In this embodiment, the first drive shaft 22 rotates to drive the triggering part 17 to move, thereby compressing the transmission part 12, so that the fluid can be sucked in and compressed from the fluid input pipe 11, and further flows out from the fluid output pipe 13, and the fluid output pipe 13 enters the hollow channel 31. It can be understood that the movement of the triggering part 17 includes rotation, swinging, telescopic, etc. In this embodiment, the preferred mode is that the triggering part 17 includes a mounting body 171 and a triggering body 172, the second output end 222 is connected to one end of the mounting body 171, drives the mounting body 171 to rotate, and the triggering body 172 is connected to the other end of the mounting body 171, and the connection position of the two is offset from the rotation axis of the mounting body 171. Specifically, the mounting body 171 has an end surface 173 at one end away from the first driving body 21, one end of the trigger body 172 is connected to the transmission part 12, and the other end is connected to the end surface 173 and deviates from the center of the end surface 173. The transmission part 12 is, for example, a soft rubber piston, and the number of the transmission parts 12 can be one or more. When the first driving shaft 22 rotates, it drives the mounting body 171 to rotate. At this time, the trigger body 172 rotates eccentrically, thereby squeezing the transmission part 12, further greatly promoting the transmission of the fluid.

[0050] For example, see Figure 5-Figure 8The input port 121 and the output port 122 of the fluid transmission member are both arranged at one end of the fluid transmission member 1 away from the first driving member 2. In this way, the space inside the housing can be fully utilized. The connection between the fluid input pipe 11 and the fluid output pipe 13 and the water pump can also be connected to the adapter 123. The water pump has an input port 122 and an output port 121. The adapter 123 includes two first interfaces 14, which are respectively connected to the input port 122 and the output port 121. The adapter 123 can also include a second interface 15 and a third interface 16. The second interface 15 is connected to the fluid input pipe 11, and the third interface 16 is connected to one end of the fluid output pipe 13. The other end of the fluid output pipe 13 is connected to the hollow channel 31. Water can enter from the fluid input pipe 11. When the first driving shaft 22 drives the water pump to work, the water flow enters through the input port 122 of the adapter 123, and enters the fluid output pipe 13 through the output port 121 of the adapter 123, thereby reaching the hollow channel 31, and further reaching the brush head.

[0051] In this embodiment, after the fluid output pipe 13 comes out of the output port 121, it surrounds the surface of the first driving body 21 and the fluid transmission member 1, and extends to the hollow channel 31 to communicate with the hollow channel 31, so as to guide the fluid to the hollow channel 31. In this way, on the basis of realizing that the fluid can enter the hollow channel 31, in this embodiment, the fluid output pipe 13 of the water pump is also attached to the surface of the first driving body 21 and the fluid transmission member 1, so as to make full use of the space in the housing 4 and shorten the length of the housing 4.

[0052] In this embodiment, the oral cleaning device 10 further includes a battery 5 and a circuit board 6. The battery 5 is disposed in the housing 4. The circuit board 6 is disposed on the outer wall of the housing 4 and connected to the battery 5. In this embodiment, the second driving member 3, the first driving body 21, the water pump and the battery 5 are sequentially disposed in the housing 4 along the length direction of the housing 4. The fluid input pipe 11 can extend around the surface of the battery 5 to near the water pump and be connected to the input port 122 of the water pump. Such a configuration can fully integrate the various structural components in the housing 4, thereby shortening the length of the housing 4. In more detail, the housing 4 includes a first housing 422 and a second housing 433. The first housing 422 and the second housing 433 are enclosed to form a receiving chamber 44. The receiving chamber is communicated with the outlet end 41. The second driving member 3, the first driving body 21, the water pump and the battery 5 are sequentially disposed in the receiving chamber 44 along the length direction of the housing 4. Among them, the circuit board 6 can be disposed in the first housing 422. The oral cleaning device 10 further includes a second sealing ring 45. The second sealing ring 45 is installed at the outlet end 41 to seal the receiving chamber 44. It can be understood that the second driving member is a rotary motor, a magnetic levitation motor or a sonic motor.

[0053] In more detail, in another embodiment, the first housing 42 is provided with a mounting groove 421, and the first housing 42 is provided with a first through hole 422, the fluid input pipe 11 is installed in the mounting groove 421, and passes through the first through hole 422 to be connected to the input port 122 of the adapter 123. In another embodiment, the second housing 43 is provided with a receiving hole 431, the fluid output pipe 13 surrounds the outer surface of the first driving body and the water pump, and is received in the receiving hole 431, thereby increasing the compactness of the structure. In more detail, the oral cleaning device 10 further includes a housing 7 to enclose the first housing 42 and the second housing 43.

[0054] Please refer to the figure, the second driving member 3 includes a second driving body 32 and a second driving shaft 33, the second driving shaft 33 is arranged on the second driving body 32, and the second driving shaft 33 has a hollow channel 31, the first driving shaft 22 passes through the hollow channel 31, and protrudes one end of the second driving shaft 33 away from the second driving body 32, so as to drive the fluid to flow out from the hollow channel 31 toward the end away from the second driving body 32. In this embodiment, the second driving body 32 is arranged in the accommodating cavity and connected to the second driving shaft 33, the brush head can be installed on the second driving shaft 33, and the second driving body 32 drives the brush head to vibrate through the second driving shaft 33, so as to facilitate the user to clean the oral cavity. Further, the second driving shaft 33 has a hollow channel 31, and the first driving shaft 22 passes through the hollow channel 31, so as to promote the fluid in the hollow channel 31 to flow out from the hollow channel 31 toward the end of the hollow channel 31 away from the second driving body 32, so as to facilitate the user to clean the oral cavity. In addition, in this embodiment, in addition to satisfying the functions of the oral cleaning device 10 being able to vibrate and flush water, the first drive shaft 22 is inserted into the hollow channel 31 of the second drive shaft 33, and the second drive body 32 can be close to the first drive body 21, thereby greatly reducing the space occupied by the required structural components in the shell 4, thereby making the oral cleaning device 10 relatively small and convenient for consumers to use.

[0055] See also Figure 3-Figure 4 At least one first channel 223 is provided at one end of the first drive shaft 22 away from the second drive body 32, and the first channel 223 is connected to the hollow channel 31 so that the fluid can flow out from the first channel 223. It is convenient for the user to clean the oral cavity. Furthermore, the outer peripheral wall of the first drive shaft 22 is radially extended with a first protrusion 224, and a first channel 223 is formed between two adjacent first protrusions 224 to limit the fluid to flow out from the first channel 223. For example, taking four first channels 223 and four first protrusions 224 as an example, the first protrusions 224 respectively separate two adjacent first channels 223, so that the fluid can flow out from multiple channels in batches. Under the action of the rotational force of the first drive shaft 22, it can also promote the fluid to flow out from multiple channels in batches to clean the user's oral cavity.

[0056] See also Figure 3-Figure 4 , at the other end, a second channel 225 is provided at the first drive shaft 22 near the first output end 221, and the end of the fluid output pipe 13 away from the output port 122 passes through the second channel 225 and the hollow channel 31 and the fluid transmission member 1, so that the fluid enters the hollow channel 31 along the second channel 225. Further, a second protrusion 226 radially extends from the outer peripheral wall of the first drive shaft 22 near the first output end 221, and a second channel 225 is formed between two adjacent second protrusions 226, so as to limit the fluid from entering the hollow channel 31 along the second channel 225. Similarly, taking four second channels 225 and four second protrusions 226 as an example, the second protrusion 226 separates two adjacent second channels 225, and under the rotation of the first drive shaft 22, the fluid in the fluid output pipe 13 is transmitted to the hollow channel 31 along the second channel 225, and the fluid is limited to enter the hollow channel 31 from the second channel 225. It is understandable that the second protrusion 226 can also largely prevent the fluid in the hollow channel 31 from flowing back to the fluid output pipe 13 from outside the second channel 225 .

[0057] See also Figure 5-Figure 6 In this embodiment, the oral cleaning device 10 further includes a first sealing ring 227 , which is sleeved on the first driving shaft 22 and disposed at the first output end 221 of the first driving body 21 to prevent fluid from entering the first driving body 21 .
