[0050] The oral care devices currently on the market mainly adopt three design methods to realize the oral irrigation function. The first is the combination design of a water pick and a liquid supply base station, wherein the liquid supply base station is internally provided with a pump body responsible for delivering water flow to the water pick to generate water flow impact. The second design is that the water pick itself integrates a pump body, so that the device can independently provide water flow impact without an additional liquid supply base station. The third is a flushing all-in-one machine, which not only integrates the irrigation function but also has the tooth brushing function, and also integrates a pump body inside to provide the required water flow impact. These designs have their own characteristics and meet the needs and use scenarios of different users, but all need to use a pump body to provide water flow impact.

[0051] However, common water pumps such as piston pumps, plunger pumps, diaphragm pumps, etc. mainly draw liquid through the stroke and extrude it into the output pipeline, which will cause water vapor to leak out in the process. Taking the piston pump as an example, in-depth research by the present application found that the pump body has a cylinder sleeve inside, and the piston reciprocates inside the cylinder sleeve to inhale and expel liquid, in which process the liquid will adhere to the inner wall of the cylinder sleeve, evaporate to form water vapor into the transmission cavity, and then spread from the transmission cavity to the motor and outward, thereby causing damage to the motor, and rust and damage to the electronic components such as the battery, circuit board, etc. inside the oral care device. Moreover, with the long-term operation of the piston, the sealing ring between the piston and the cylinder sleeve can also be damaged or deformed, thereby causing liquid leakage, which will also cause damage to the motor, and rust and damage to the electronic components such as the battery, circuit board, etc. inside the oral care device.

[0052] The present application attempts to install two sealing rings on the piston to improve the sealing performance between the piston and the inner wall of the cylinder liner by increasing the number of sealing rings, thereby avoiding water leakage. However, this solution also increases the friction between the piston and the cylinder liner, which requires more power to drive the piston, and still cannot avoid the liquid from being splashed on the inner wall of the cylinder liner and evaporating and leaking.

[0053] The present application attempts to install two sealing rings on the piston to improve the sealing performance between the piston and the inner wall of the cylinder liner by increasing the number of sealing rings, thereby avoiding water leakage. However, this solution also increases the friction between the piston and the cylinder liner, which requires more power to drive the piston, and still cannot avoid the liquid from being splashed on the inner wall of the cylinder liner and evaporating and leaking.

[0054] Therefore, the present application finally divides the main body cavity formed by the main shell of the oral care device into a first space and a second space, and places the fluid pumping component generating the humid fluid in the first space, and places the driving unit and electronic devices susceptible to damage by the humid fluid in the second space, thereby achieving dry and wet separation, reducing the possibility of humid fluid leakage damaging the electronic devices inside the oral care device, and improving the service life of the oral care device.

[0055] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0056] Please see Figures 1 to 5In an implementable embodiment, the oral care device can at least include a main housing 100, a housing component 200, a fluid pumping component 300, electronic devices 400 and a driving unit 500. The main housing 100 serves as a bearing component of the oral care device, and mainly functions to support and protect the remaining components in the oral care device. Specifically, the main housing 100 has an outer wall and a main cavity 110 formed by the outer wall. The housing component 200 is arranged in the main cavity 110, and divides the main cavity 110 into a first space 111 and a second space 112 which are isolated and sealed from each other. The fluid pumping component 300 is arranged in the first space 111, and is in communication with a fluid source 700 through a fluid guide channel 600. The electronic devices 400 and the driving unit 500 are arranged in the second space 112, and the driving unit 500 drives the fluid pumping component 300 to operate, so as to draw fluid in the fluid source 700 through the fluid guide channel 600 and output water flow.

[0057] That is, the fluid pumping component 300 which can leak wet fluid is arranged in the first space 111, and the electronic devices 400 and the driving unit 500 which are vulnerable to wet fluid are arranged in the second space 112. In this way, even when the fluid pumping component 300 leaks wet fluid, the wet fluid is prevented from entering the second space 112 through the first space 111, so as to avoid damaging the electronic devices 400 and the driving unit 500.

[0058] In actual application, the main housing 100 can be formed by splicing an upper cover body and a housing, or by splicing an upper cover body, a lower cover body and a housing, and the like, which is not limited in the present application. The splicing positions of the main housing 100 should be provided with waterproof structures, so as to prevent external wet fluid from entering the main cavity 110 and damaging the electronic devices 400 and the driving unit 500 in the main cavity 110.

[0059] The fluid pumping component 300 can be a diaphragm pump, a plunger pump or a piston pump, and the driving unit 500 can be a cylinder or a motor, but considering the controllability of the motor and the simple and easy-to-implement electric control structure, the present application preferably uses a motor as the driving unit 500.

[0060] The electronic devices 400 can be one or more of a PCB board 410, a battery 420, a button assembly, and the like.

[0061] The fluid source 700 can be integrated into the oral care device. It can be connected to the main housing 100 to form a structure similar to an integrated water flosser. Accordingly, a waterproof structure should be provided between the fluid source 700 and the main housing 100 to prevent liquid from the fluid source 700 from leaking directly into the main chamber 110. Alternatively, the fluid source 700 can be separated from the main housing 100 and connected via a flexible hose. In this case, the fluid source can be an external water tank or other water supply component. Of course, the fluid source 700 can also be independent of the oral care device and can be a faucet or other water supply component.

[0062] Considering the possibility of leakage at the connection between the flow channel 600 and the fluid pumping component 300, and the potential for moisture in the external environment to condense into water droplets and form a damp fluid on the outer wall of the flow channel 600 when the main chamber 110 is poorly sealed, at least a portion of the flow channel 600 can be placed within the first space 111. This also avoids the possibility of leakage from the flow channel 600 damaging the drive unit 500 and electronic components 400 inside the oral care device, thereby extending the service life of the oral care device.

[0063] Regarding the specific manner in which the housing component 200 divides the main chamber 110 into a first space 111 and a second space 112, this application provides three feasible embodiments for reference.

[0064] Example 1, such as Figure 1 As shown, the housing component 200 may include a partition 210, which is coupled to the inner wall of the main housing 100, thereby dividing the main chamber 110 into a first space 111 and a second space 112.

[0065] Example 2, as follows Figure 2 As shown, the housing component 200 may include a partition 210 and a second outer shell component 230, wherein the partition 210 and the second outer shell component 230 together form a first space 111, and the outer surface of the partition 210 and the second outer shell component 230 together with the main housing 100 forms a second space 112.

[0066] The partition 210 or the second outer shell 230 can also be coupled to the inner wall of the main shell 100, thereby further dividing the second space 112 into multiple spaces. Alternatively, a second partition is also provided in the main cavity 110, and the second partition is coupled to the inner wall of the main cavity 110, thereby further dividing the second space 112 into multiple spaces.

[0067] Example 3, as follows Figure 3As shown, the housing component 200 includes a partition 210 and a first outer shell component 220, which together form a second space 112. The outer surface of the partition 210 and the first outer shell component 220 together forms a first space 111 with the main housing 100.

[0068] Understandably, this method not only prevents the leakage of wet fluid from the fluid pumping component 300 from damaging the electronic device 400 and the drive unit 500, but also prevents the leakage of wet fluid from damaging the electronic device 400 and the drive unit 500 even if external water leaks through the main housing 100 into the main body chamber 110.

[0069] like Figures 6 to 8 As shown, in one feasible embodiment, a first sealing member 240 is provided on the mating surface of the separator 210 and the first housing 220. The first sealing member 240 seals the mating gap between the separator 210 and the first housing 220, thereby preventing the humid fluid leaking from the fluid pumping component 300 from entering the second space 112 through the mating gap between the separator 210 and the first housing 220 and damaging the electronic device 400 and the drive unit 500.

[0070] In practical applications, the partition 210 and the first outer shell 220 can be provided with snap-fit ​​structures around them, allowing them to be interlocked and spliced ​​together as a single unit; and / or, the partition 210 and the first outer shell 220 can be spliced ​​together by screws. The mating surfaces of the partition 210 and / or the first outer shell 220 can be provided with mounting grooves, and the first seal 240 can be pre-installed in these grooves, so that when the partition 210 and the first outer shell 220 are spliced ​​together, the first seal 240 fills the gap between them. Alternatively, one of the partition 210 and the first outer shell 220 can be integrally formed with the first seal 240 through secondary injection molding, while the other is interference-fitted to the first seal 240.

[0071] In an optional embodiment, the separator 210 or the first housing 220 may be provided with a sealed transmission mechanism. This transmission mechanism forms part of the separator 210 or the first housing 220 and participates in the isolation and sealing of the first space 111 and the second space 112. Simultaneously, the transmission mechanism has two ends capable of transmitting power, one end located within the second space 112 and connected to the output end of the drive unit 500, and the other end located within the first space 111 and connected to the fluid pumping component 300. The drive unit 500 can drive the fluid pumping component 300 to operate via the transmission mechanism. This prevents humid fluid in the first space 111 from leaking into the second space 112 through the transmission gap between the drive unit 500 and the fluid pumping component 300.

[0072] like Figure 8 and Figure 9 As shown, in another optional embodiment, the separator 210 or the first housing 220 is provided with a first clearance hole 2141, the output end of the drive unit 500 extends through the first clearance hole 2141 into the first space 111, and a second seal 250 is filled between the output end and the first clearance hole 2141. This prevents humid fluid in the first space 111 from leaking into the second space 112 through the gap between the output end of the drive unit 500 and the first clearance hole 2141.

[0073] In practical applications, the second seal 250 can be a sealing ring. The outer periphery of the sealing ring is fixed to the inner wall surface of the first clearance hole 2141, and the inner side of the second seal 250 is sleeved on the output end and contacts the output end.

[0074] Considering that control buttons also need to be installed on the main housing 100 of the oral care device, and that these control buttons need to be pressed to contact the buttons on the PCB board 410 in the second space 112, a button hole 221 also needs to be provided on the first housing component 220. Correspondingly, the housing component 200 may also include a button seal 260, which is coupled to the PCB board 410 and seals the button hole 221, thereby preventing humid fluid in the first space 111 from leaking into the second space 112 through the button hole 221.

[0075] like Figure 4 and Figure 5 As shown, based on the above embodiment 3, the housing component 200 may further include a second outer shell component 230. The second outer shell component 230 is located within the first space 111, and is coupled to the separator 210. The second outer shell component 230 divides the first space 111 into a third space 113 and a fourth space 114.

[0076] The third space 113 is formed by the partition 210 and the second housing 230, and the fluid pumping component 300 is assembled in the third space 113. The fourth space 114 is formed by the outer surface of the combination of the partition 210, the first housing 220 and the second housing 230 and the main housing 100, and the fluid guide channel 600 is at least partially located in the fourth space 114. In this way, the partition 210, the first housing 220 and the second housing 230 can integrate the fluid pumping component 300, the electronic device 400 and the driving unit 500 into one whole, so as to be integrally installed in or detached from the main cavity 110, facilitating the disassembly and assembly operation.

[0077] In the embodiment, the fourth space 114 can be arranged around the second space 112 and / or the fourth space 114 is arranged around the third space 113 from the perspective of the vertical section of the oral care device, and the housing component 200 formed by the partition 210, the first housing 220 and the second housing 230 forms a visual effect similar to suspension in the main cavity 110. In addition, this arrangement can facilitate the communication of the fluid guide channel 600 with the fluid source 700 located below, and facilitate the arrangement of the fluid guide channel 600.

[0078] In actual application, the partition 210 and the second housing 230 can be provided with a buckle structure, and the partition 210 and the second housing 230 are integrally connected by the buckle structure; and / or the partition 210 and the second housing 230 can be integrally connected by screw locking.

[0079] In an implementable embodiment, the third sealing member (not shown) is arranged at the joint surface of the partition 210 and the second housing 230, and the sealing gap between the partition 210 and the second housing 230 is sealed by the third sealing member, so as to limit the humid fluid leaked from the fluid pumping component 300 in the third space 113, avoid the humid fluid leaked from the fluid pumping component 300 from leaking into the fourth space 114, and then leaking to the outside of the main housing 100 or entering the second space 112.

[0080] In other words, the partition 210 and the second housing 230 jointly form the housing structure of the fluid pumping component 300, and the fluid pumping component 300 is isolated and sealed by the partition 210 and the second housing 230, so as to avoid the fluid leaked from the fluid pumping component 300 from leaking outside. In this way, the partition 210 and the second housing 230 can utilize their own high strength and not easy to be damaged, and the partition 210 and the second housing 230 do not need to move with the driving unit 320 in the fluid pumping component 300, so as to avoid fatigue damage, thereby ensuring the reliability and service life of the sealing of the fluid pumping component 300.

[0081] In practical applications, the joint surface of the partition member 210 and / or the joint surface of the second housing member 230 can be provided with a mounting groove, and a third sealing member can be pre-installed in the mounting groove, so that when the partition member 210 and the second housing member 230 are spliced with each other, the third sealing member is filled in the joint gap between the partition member 210 and the second housing member 230. Of course, one of the partition member 210 and the second housing member 230 can be integrally formed with the third sealing member by means of secondary injection molding, and the other is connected with the third sealing member in an interference fit.

[0082] As to the specific structure of the fluid pumping component 300, as shown in Figure 4 、 Figure 5 、 Figures 8 to 10 in an implementable embodiment, the fluid pumping component 300 can include an execution unit 310 and a transmission unit 320, and the driving unit 500 drives the execution unit 310 to move through the transmission unit 320 to extract the fluid in the fluid source 700 and discharge the fluid. Among them, the execution unit 310 can adopt different structures according to the specific form of the fluid pumping component 300, for example, when the fluid pumping component 300 is a diaphragm pump, the execution unit 310 can be a diaphragm structure, and when the fluid pumping component 300 is a piston pump, the execution unit 310 can be a piston structure.

[0083] Taking the execution unit 310 as a piston structure as an example, the execution unit 310 can include a pump body 311 and a piston 312, the pump body 311 has a first inlet 3111 and a first outlet 3112, and the piston 312 is slidingly arranged in the pump body 311, so that the reciprocating motion of the piston 312 in the pump body 311 can be used to extract the fluid from the first inlet 3111 and discharge the fluid from the first outlet 3112.

[0084] In practical applications, the pump body 311 can be made of copper, alloy or other high-strength materials. The partition member 210 and the second housing member 230 can be injection molded. The pump body 311 can also be composed of two parts. Specifically, the pump body 311 includes a pump housing and a cylinder sleeve, the cylinder sleeve is arranged in the pump housing, and the piston 312 is slidingly arranged in the cylinder sleeve, which only needs to improve the wear resistance of the cylinder sleeve to meet the use requirements, thereby further reducing the processing requirements and reducing the production cost.

[0085] Regarding the specific structure of the transmission unit 320, in one feasible embodiment, the transmission unit 320 may include a first gear 321, an end-face eccentric gear 322, and a connecting rod 323. The end-face eccentric gear 322 is rotatably connected to the separator 210 and / or the second housing 230. The first gear 321 is connected to the output end of the drive unit 500 and meshes with the gear portion of the end-face eccentric gear 322. The eccentric portion of the end-face eccentric gear 322 is connected to one end of the connecting rod 323, and the other end of the connecting rod 323 is connected to the execution unit 310. When the execution unit 310 is a piston structure, the other end of the connecting rod 323 is connected to the piston 312. When the drive unit 500 drives the first gear 321 to rotate, the first gear 321 can drive the eccentric portion of the end-face eccentric gear 322 to perform eccentric motion, and the connecting rod 323 converts the eccentric motion into linear motion, thereby driving the piston 312 to perform linear reciprocating motion.

[0086] The eccentric portion of the aforementioned end-face eccentric gear 322 and the connecting rod 323 and the first gear 321 can be located on opposite sides of the gear portion of the end-face eccentric gear 322.

[0087] The eccentric portion of the first gear 321, the end face eccentric gear 322, and the connecting rod 323 can also be located on the same side of the gear portion of the end face eccentric gear 322. The first gear 321, the eccentric portion of the end face eccentric gear 322, and the connecting rod 323 share the same thickness space, thereby reducing the overall thickness of the fluid pumping component 300 and making the main housing 100 thinner, so as to facilitate user grip and operation.

[0088] like Figure 4 As shown, in one feasible embodiment, the main housing 100 has a main extension line a, and the drive unit 500, transmission unit 320, and execution unit 310 are arranged along the main extension line a. This allows the main extension direction of the fluid pumping component 300 to be aligned with the main extension direction of the main housing 100, making full use of the shape of the main housing 100 to arrange the fluid pumping component 300, avoiding the need for an excessively large main housing 100 that would affect the user's grip. Simultaneously, this arrangement design also allows sufficient space between the sides of the fluid pumping component 300 and the main housing 100 to accommodate the electronic device 400. That is, the electronic device 400 and the fluid pumping component 300 are arranged perpendicular to the main extension line a, thereby shortening the overall length of the oral care device and making it easier to carry.

[0089] In an implementable embodiment, the piston 312 can be connected with a piston sealing ring, which is used to prevent the wet fluid in the pump body 311 from leaking through the gap between the piston 312 and the cylinder sleeve. The cylinder sleeve is sleeved with an O-ring, which is used to prevent the wet fluid in the pump body 311 from leaking through the gap between the cylinder sleeve and the overall inner wall surface formed by the partition 210 and the second housing 230, thereby further reducing the possibility of liquid leakage.

[0090] It can be understood that the sealing arrangement of the piston sealing ring and the O-ring can also divide the third space 113 into an execution cavity and a transmission cavity that are sealed from each other. The transmission unit 320 is arranged in the transmission cavity, and the execution unit 310 is arranged in the execution cavity. In order to further reduce the harmfulness of the wet fluid leakage, the partition 210 and / or the second housing 230 can be provided with a communication hole in communication with the transmission cavity, and the communication hole is in communication with the external environment through a flow guide pipe. In this way, when the wet fluid in the execution cavity leaks into the transmission cavity, the wet fluid can flow into the external environment through the flow guide pipe, thereby avoiding the long-term retention of the wet fluid in the transmission cavity, damaging the corresponding sealing structure, and further avoiding the possibility of the wet fluid leaking out of the third space 113.

[0091] The oral care device of the present application can be a waterpik or a flusher all-in-one device. Taking the flusher all-in-one device as an example, the oral care device can further include a brush head and a motor. The brush head has a transmission flow channel and a communication port and a liquid jet port at both ends of the transmission flow channel. The brush head can be provided with bristles, and the bristles are located at one end of the brush head provided with the liquid jet port. The motor has a power output shaft, and the motor is connected to the brush head through the power output shaft to drive the brush head to perform cleaning movement. The power output shaft is configured as a hollow shaft, and the first outlet 3112 of the fluid pumping component 300 is in communication with the transmission flow channel in the brush head through the power output shaft, so that the fluid pumped by the fluid pumping component 300 can pass through the power output shaft and the transmission flow channel in sequence, and finally output water flow impact from the liquid jet port.

[0092] Taking the oral care device as a waterpik as an example, the oral care device further includes a liquid guide connector 610 and a nozzle head 800. The first inlet 3111 of the fluid pumping component 300 is in communication with the fluid source 700 through the flow guide channel 600, and the first outlet 3112 of the fluid pumping component 300 is in communication with the nozzle head 800 through the liquid guide connector 610.

[0093] Based on the same inventive concept, the application also provides a fluid pumping assembly for oral cleaning, comprising a partition 210, a first housing member 220, a second housing member 230, a fluid pumping component 300, electronic devices 400 and a driving unit 500, wherein the first housing member 220 and the second housing member 230 are respectively located on opposite sides of the partition 210, the first housing member 220 and the partition 210 form a third space 113, the second housing member 230 and the partition 210 form a first space 111, the fluid pumping component 300 is assembled in the first space 111, and the electronic devices 400 and the driving unit 500 are assembled in the third space 113.
