[0003] This application relates to the field of oral care technology, and in particular to an oral care device and a device having a fluid pumping mechanism. Background Technology
[0004] Oral care devices with oral rinsing functions are usually equipped with a pump, which draws liquid from the tank and outputs a water flow to the user's mouth for oral cleaning.
[0005] However, during use, the pump body may leak moisture, increasing air humidity, or even leak liquid. These situations can cause corrosion and damage to electronic components such as batteries and circuit boards inside the oral care equipment. Summary of the Invention
[0006] The purpose of this application is to provide an oral care device and a device with a fluid pumping mechanism, which can reduce the humidity in the main chamber, avoid damage to the electronic components inside the oral care device, and improve its service life.

[0027] Currently, oral care devices on the market primarily employ three design approaches to achieve oral rinsing functionality. The first is a combination design of the water flosser and a water supply station, where the water supply station has a built-in pump responsible for delivering water flow to the water flosser to generate a water jet. The second design integrates the water flosser itself with a pump, allowing the device to provide water jet independently without an additional water supply station. The third is a combined rinsing and brushing device, which integrates both rinsing and brushing functions, and also incorporates a pump to provide the necessary water jet. These designs each have their own characteristics, meeting the needs of different users and usage scenarios, but all require a pump to provide the water jet.
[0028] However, commonly used water pumps, such as piston pumps and diaphragm pumps, primarily draw liquid through a stroke and compress it into the output pipe. This process can lead to water vapor leakage. Specifically, taking piston pumps as an example, this application's in-depth research reveals that the pump body has a cylinder liner. The piston reciprocates within the cylinder liner to draw in and discharge liquid. During this process, liquid adheres to the inner wall of the cylinder liner, evaporates, and forms water vapor that enters the transmission chamber. This vapor then escapes from the transmission chamber towards the motor and outwards, causing damage to the motor and corrosion and damage to electronic components such as batteries and circuit boards within the oral care device. Furthermore, with prolonged piston operation, the seal between the piston and the cylinder liner may also break or deform, leading to liquid leakage, which similarly damages the motor and causes corrosion and damage to electronic components such as batteries and circuit boards within the oral care device.
[0029] This application attempted to install two sealing rings on the piston to improve the sealing performance between the piston and the cylinder liner inner wall by increasing the number of sealing rings, thus preventing water leakage. However, this solution also correspondingly increases the friction between the piston and the cylinder liner, requiring more power to drive the piston, and still cannot prevent liquid from sticking to the cylinder liner inner wall and evaporating and leaking.
[0030] This application also attempts to install an accordion-shaped sealing sleeve between the outer wall of the cylinder liner or the outer wall of the pump housing and the connecting rod that drives the piston. This sealing sleeve isolates the liquid adhering to the inner wall of the cylinder liner from the outside, preventing the liquid from evaporating and spreading outwards. While this solution can prevent liquid and moisture leakage, the sealing sleeve is prone to damage and aging because it needs to move with the connecting rod, resulting in a short service life. Furthermore, even after damage and aging, leakage can still occur, potentially damaging electronic components.
[0031] Therefore, this application proposes a new improvement scheme to prevent damage to the electronic components inside the oral care device from humid fluids by preventing the ingress of external moisture (liquid or water vapor) and by guiding leaked internal moisture to the outside. Specifically, by highly sealing the entire oral care device to achieve spatial isolation, external moisture is prevented from entering the device. Simultaneously, through-holes are provided to connect the internal space of the device with the external environment, allowing leaks and moisture to drain out promptly. This reduces the internal humidity of the device, preventing damage to the internal electronic components and extending its lifespan.
[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.
[0033] Referring to Figures 1 to 4, in one feasible embodiment, the oral care device may include at least a main housing 100, a fluid pumping mechanism 200, and electronic components 300. The main housing 100 serves as the load-bearing component of the oral care device, primarily supporting and protecting the other components. Specifically, the main housing 100 has a main chamber 110, within which the fluid pumping mechanism 200 is located. The fluid pumping mechanism 200 draws liquid through a stroke and compresses it into an output pipe, providing kinetic energy to transport the liquid. The fluid pumping mechanism 200 includes a housing component 210, the outer surface of which and the main housing 100 form a first space 111, within which the electronic components 300 are located. Thus, the housing component 210 can, to a certain extent, isolate the internal components of the fluid pumping mechanism 200 from the electronic components 300, preventing leaked liquid from the fluid pumping mechanism 200 from directly splashing onto the electronic components 300, providing a degree of protection.
[0034] Meanwhile, considering that the fluid pumping mechanism 200 located inside the main chamber 110 may leak humid fluid, which could still lead to an increase in humid fluid inside the main chamber 110 and damage the drive unit 230 and electronic components 300 of the fluid pumping mechanism 200, this embodiment provides an interface 120 on the main housing 100. At least a portion of the space inside the main chamber 110 can communicate with the external environment through the interface 120, allowing the humid fluid inside the main chamber 110 to be discharged to the external environment through the interface 120. This reduces the humidity inside the main chamber 110, prevents damage to the drive unit 230 and electronic components 300 of the fluid pumping mechanism 200, and further improves the service life of the oral care device.
[0035] It should be noted that the interface 120 may not have a filtering function. It not only allows the humid fluid inside the main chamber 110 to be discharged to the external environment, but also allows dry gas inside the main chamber 110 to pass through with dry gas in the external environment. Oral care equipment refers to equipment that integrates a fluid pumping mechanism 200 and is used for oral care. This may include, but is not limited to, a fluid supply base in a combined design of a water flosser and a fluid supply base, a water flosser with an integrated fluid pumping mechanism, and a combined water flosser and brushing machine.
[0036] In practical applications, electronic device 300 may include, but is not limited to, one or more of the following: battery, PCB board 310, motor, and display screen.
[0037] Except for the interface 120, which connects the main chamber 110 to the external environment, the rest of the main housing 100 can be sealed to isolate the main chamber 110 from the external environment as much as possible. This achieves internal and external dry-wet isolation, preventing external moisture from entering the main chamber 110 through the main housing 100 and thus increasing the moisture content inside the main chamber 110, which could damage the drive unit 230 of the fluid pumping mechanism 200 and the electronic components 300. The method by which the main housing 100 forms a relatively sealed main chamber 110 may vary depending on the type of oral care device. Taking an oral care device as an example of a liquid supply base, as shown in Figures 1 and 2, the main housing 100 may include a main body 101 with an upper opening and a lower opening, a lower cover 102, and an upper cover 103. The lower cover 102 is located at the lower opening of the main body 101, and the upper cover 103 is located at the upper opening of the main body 101. The lower cover 102 and the upper cover 103 can be sealed with the main body 101 using sealant or adhesive, so that the main body 101, the lower cover 102, and the upper cover 103 together form a relatively sealed main body chamber 110. An adjustment button may also be provided on the upper cover 103, but the assembly gap between the adjustment button and the upper cover 103 also needs to be sealed to ensure the high airtightness of the main body chamber 110. Taking a water flosser with an integrated fluid pumping mechanism 200 as an example, as shown in Figure 5, the main housing 100 of the water flosser is shaped like a handle. The main housing 100 may include at least a main body 101 with an upper opening and a top cover 103. The top cover 103 is located at the upper opening of the main body 101. The top cover 103 and the main body 101 are sealed with a sealant or glue, so that the main body 101 and the top cover 103 together form a relatively sealed main body chamber 110. The top cover 103 may be provided with a connector for connecting a nozzle. The assembly gap between the connector and the top cover 103 also needs to be sealed to ensure the high airtightness of the main body chamber 110.
[0038] It is worth mentioning that this application also seals the main chamber 110 to a certain extent through the main housing 100, achieving spatial isolation and reducing the possibility of humid fluids from the external environment entering the main chamber 110. Simultaneously, by connecting at least a portion of the space within the main chamber 110 to the external environment through the interface 120, allowing humid fluids within the main chamber 110 to be discharged to the external environment through the interface 120, the influence of internal and external humid fluids on the humidity within the main chamber 110 is comprehensively considered. This reduces the possibility of damage to the drive unit 230 of the fluid pumping mechanism 200 and the electronic components 300 caused by internal and external humid fluids, minimizing the humid fluid content within the main chamber 110 and extending the service life of the oral care device.
[0039] In practical applications, the interface 120 can be located at any position on the main housing 100, allowing moisture in the main chamber 110 to be discharged to the external environment. The interface 120 can be equipped with a waterproof and breathable component to prevent liquids from the external environment from entering the main chamber 110 through the interface 120. Considering that the liquid in the main chamber 110 can be discharged to the external environment and to prevent the entry of external humid fluids, the interface 120 can be located at the bottom of the main housing 100. For example, when the oral care device is a liquid supply base station, the interface 120 is located on the lower cover 102. In this way, when there is liquid in the main chamber 110, the liquid can flow out from the interface 120 under gravity, while also preventing the entry of liquids from the external environment. Of course, in order to facilitate the flow of liquid in the main chamber 110 to the interface 120 and out of the interface 120, the inner wall surface of the main shell 100 forming the main chamber 110 can also be provided with a guide groove, and the liquid in the main chamber 110 can be guided to the interface 120 by the guide groove.
[0040] Regarding a specific implementation of a method in which at least a portion of the space within the main chamber 110 is connected to the external environment through an interface 120, so that humid fluid within the main chamber 110 is discharged to the external environment through the interface 120, this application provides two feasible embodiments for reference.
[0041] In Embodiment 1, as shown in Figures 3 and 4, the fluid pumping mechanism 200 further includes an execution unit 220, a drive unit 230, and a transmission unit 240. The housing component 210 has at least an execution cavity 211 and a transmission cavity 212. Both the execution cavity 211 and the transmission cavity 212 are isolated and sealed from the first space 111, thereby preventing the humid fluid in the execution cavity 211 and the transmission cavity 212 from flowing directly into the first space 111. The execution unit 220 is located in the execution cavity 211, and the transmission unit 240 is located in the transmission cavity 212 and partially extends into the execution cavity 211 and is connected to the execution unit 220. The output end of the drive unit 230 extends into the transmission cavity 212 and is connected to the execution unit 220 through the transmission unit 240. Thus, the drive unit 230 drives the execution unit 220 to move through the transmission unit 240, so as to draw liquid from the inlet of the execution cavity 211 into the execution cavity 211 and discharge it from the outlet of the execution cavity 211. Considering that the humid fluid generated by the fluid pumping mechanism 200 mainly comes from the liquid leaking into the transmission cavity 212 and the water vapor evaporating into the transmission cavity 212, this embodiment connects the interaction port 120 with the transmission cavity 212, so that the humid fluid generated by the fluid pumping mechanism 200 is discharged to the external environment through the interaction port 120 via the transmission cavity 212.
[0042] Thus, this embodiment effectively discharges humid fluid directly into the external environment from the source, preventing it from flowing into the first space 111 and thus avoiding damage to the drive unit 230 and electronic components 300 of the fluid pumping mechanism 200. Furthermore, even if humid fluid from the external environment enters the interaction port 120, it prevents it from entering the first space 111 and damaging the drive unit 230 and electronic components 300 of the fluid pumping mechanism 200.
[0043] In practical applications, the fluid pumping mechanism 200 can be a pump body structure such as a piston pump or a diaphragm pump. Taking a piston pump as an example, the execution unit 220 is a piston, the drive unit 230 is a motor, and the transmission unit 240 includes a gear set 241 and a connecting rod 242. The motor is connected to one end of the gear set 241, and the other end of the gear set 241 is connected to the piston through the connecting rod 242. Thus, the motor drives the transmission unit to convert rotational motion into reciprocating motion, thereby driving the piston to reciprocate to extract and squeeze out liquid. Oral care equipment usually also includes a water tank 600, which is located outside the main chamber 110. The inlet of the execution chamber 211 can be connected to the water tank 600 through an inlet pipe, thereby preventing the water tank 600 from leaking moist fluid and damaging the drive unit 230 and electronic components 300.
[0044] In one feasible embodiment, the housing component 210 is provided with a communication hole 218, which is connected to the interface port 120 via a pipe 400, and the communication hole 218 has a component along the direction of gravity. In this way, the moist fluid in the transmission cavity 212 is discharged to the external environment in sequence through the communication hole 218, the pipe 400 and the interface port 120.
[0045] The housing component 210 has a portion surrounding the formation of the transmission cavity 212. A connecting hole 218 is located at the bottom of this portion of the housing component 210 along the direction of gravity, and / or, an interaction port 120 is located at the bottom of the main housing 100 along the direction of gravity. Thus, both the connecting hole 218 and the interaction port 120 are located at the lowest point of their respective parts, thereby maximizing the drainage of all moist fluid from the transmission cavity 212 and reducing the likelihood of damage to the electronic components 300 and the drive unit 230.
[0046] It should be noted that the direction of gravity defined in this application usually refers to the direction of gravity in the conventional placement state of the oral care equipment, or can be understood as the direction of gravity when the bottom surface of the main housing 100 is placed on the horizontal plane.
[0047] In the second embodiment, as shown in Figure 1, the aforementioned interface 120 can communicate with the first space 111. The humid fluid generated within the fluid pumping mechanism 200 is discharged to the external environment through the interface 120 via the first space 111. Specifically, water vapor formed by the evaporation of liquid adhering to the cylinder liner within the fluid pumping mechanism 200, or leaked liquid, first enters the transmission chamber 212 of the fluid pumping mechanism 200, then leaks through the transmission chamber 212 into the first space 111, and is subsequently discharged to the external environment from the first space 111 through the interface 120.
[0048] In practical applications, the execution chamber 211 and transmission chamber 212 of the fluid pumping mechanism 200 can also be isolated and sealed from the first space 111 to prevent humid fluid in the execution chamber 211 and transmission chamber 212 from flowing directly into the first space 111. In this embodiment, by connecting the interaction port 120 to the first space 111, the humid fluid in the first space 111 can be discharged to the external environment when humid fluid in the execution chamber 211 and / or transmission chamber 212 accidentally leaks into the first space 111. The specific structure of the fluid pumping mechanism 200 can be referred to the description in the above embodiment, and will not be repeated here.
[0049] To further reduce the possibility of damage to the drive unit 230 and electronic device 300 caused by the humid fluid generated by the fluid pumping mechanism 200, in one feasible embodiment, the housing component 210 of the fluid pumping mechanism 200 encloses a second space 112, within which the execution chamber 211, transmission chamber 212, execution unit 220, and transmission unit 240 of the fluid pumping mechanism 200 are located. This effectively isolates the electronic device 300 from the components within the fluid pumping mechanism 200 that generate humid fluid. Thus, when the interface 120 cannot effectively discharge the humid fluid generated by the fluid pumping mechanism 200 to the external environment, the humid fluid remaining in the main chamber 110 cannot contact the electronic device 300 and cause damage.
[0050] As shown in Figure 3, in one optional embodiment, a partition 500 may be provided inside the main housing 100. The partition 500 is coupled to the main housing 100, thereby dividing the first space 111 into a mutually isolated and sealed third space 113 and a fourth space 114. The electronic device 300 is located in the third space 113, and the fluid pumping mechanism 200 is located in the fourth space 114. In this way, even if the humid fluid in the second space 112 leaks, the humid fluid will only leak into the fourth space 114. The partition 500 can prevent the humid fluid from further leaking into the third space 113 and damaging the electronic device 300, thus reducing the scope of damage caused by leakage.
[0051] Correspondingly, when the aforementioned interaction port 120 is connected to the first space 111, the interaction port 120 should be connected to the third space 113 in the first space 111.
[0052] In this embodiment, the third space 113 and the fourth space 114 can be arranged side by side in a horizontal direction. The fourth space 114 can also be located below the third space 113, so that the possibility of liquid leakage into the third space 113 can be further reduced by utilizing the gravity of the liquid itself.
[0053] In practical applications, the partition 500 can be integrally designed with the main housing 100, thereby simplifying the assembly process and ensuring the sealing performance between the partition 500 and the main housing 100. Alternatively, the partition 500 and the main housing 100 can be designed separately and then connected to each other, with a sealing structure provided between the assembly of the partition 500 and the main housing 100. The partition 500 may have wiring holes to allow the drive unit 230 of the fluid pumping mechanism 200 to be linearly connected to at least some of the electronic components 300 through the wiring holes; however, the wiring holes need to be sealed to ensure that the third space 113 and the fourth space 114 are mutually isolated and sealed.
[0054] Of course, to further reduce damage caused by leakage of moist fluid, the electronic device 300 and the drive unit 230 of the fluid pumping mechanism 200 can both be located in the third space 113, and the remaining components of the fluid pumping mechanism 200 after removing the drive unit 230 can be located in the fourth space 114. In this way, when moist fluid leaks in the second space 112, the partition 500 can prevent the moist fluid from leaking further into the third space 113 and damaging the electronic device 300 and the drive unit 230, further reducing the scope of damage caused by leakage.
[0055] As shown in Figures 5 to 7, in another optional embodiment, the housing component 210 may include a first housing component 213 and a second housing component 214 coupled to each other, and a pump body 219. The first housing component 213, the second housing component 214, and the pump body 219 together enclose a second space 112, which is divided into an execution chamber 211, a transmission chamber 212, and a drive chamber 215 for accommodating the drive unit 230. The transmission chamber 212 is isolated and sealed from the drive chamber 215, thereby preventing humid fluid in the transmission chamber 212 from entering the drive chamber 215 and damaging the drive unit 230. Accordingly, when the aforementioned interaction port 120 communicates with the transmission chamber 212, the communication hole 218 may be formed on the first housing component 213 or the second housing component 214. In practical applications, the execution chamber 211 may be located inside the pump body 219, and correspondingly, the inlet and outlet of the execution chamber 211 are formed on the pump body 219.
[0056] Regarding the specific structure for isolating and sealing the transmission cavity 212 and the drive cavity 215, as shown in Figures 7 to 10, in one feasible embodiment, a first sealing member 216 is provided at the splicing surface of the first housing member 213 and / or the second housing member 214, and the first sealing member 216 surrounds the transmission cavity 212. Furthermore, the first housing member 213 or the second housing member 214 is provided with a first clearance hole 2131, through which the output end of the drive unit 230 extends into the transmission cavity 212. A second sealing member 217 is filled between the output end and the first clearance hole 2131, thereby isolating and sealing the drive cavity 215 and the transmission cavity 212 using the first sealing member 216 and the second sealing member 217, preventing humid fluid from leaking into the drive cavity 215 through the splicing surface of the first housing member 213 and the second housing member 214, or through the first clearance hole 2131.
[0057] Furthermore, the first sealing element 216 can also be arranged around the drive cavity 215. Meanwhile, considering that the drive unit 230 needs to be linearly connected to the electronic device 300 in the first space 111, the first housing 213 or the second housing 214 is provided with a wire harness connection hole 2132 communicating with the drive cavity 215. The tab of the drive unit 230 is located at the wire harness connection hole 2132. The tab of the drive unit 230 is connected to the electronic device 300 through the wire harness passing through the wire harness connection hole 2132, and the wire harness connection hole 2132 is filled with sealant.
[0058] Thus, the first seal 216 can simultaneously seal the joint gap of the transmission cavity 212 and the joint gap of the drive cavity 215, serving two purposes and reducing assembly frequency. Furthermore, the first seal 216 and the sealant can also isolate and seal the drive cavity 215 from the first space 111. Therefore, even if humid fluid in the transmission cavity 212 leaks into the drive cavity 215 through the joint of the first housing 213 and the second housing 214, or through the first clearance hole 2131, the sealing structure of the drive cavity 215 can confine the humid fluid within the drive cavity 215, preventing further spread of the fault and further improving the waterproofing effect.
[0059] In practical applications, the first seal 216 can be formed into a housing assembly by secondary injection molding of either the first housing part 213 or the second housing part 214, thereby simplifying the assembly process. Of course, the splicing surfaces of the first housing part 213 and / or the second housing part 214 can also be provided with receiving grooves. The first seal 216 is first pre-positioned and installed in the receiving groove, and then the first housing part 213 and the second housing part 214 are spliced and connected.
[0060] As shown in Figure 11, in another optional embodiment, the housing component 210 includes a first outer shell 213 and a second outer shell 214 coupled to each other, and a pump body 219. The first outer shell 213, the second outer shell 214, and the pump body 219 together enclose a second space 112, which is divided into an execution chamber 211 and a transmission chamber 212. The drive unit 230 of the fluid pumping mechanism 200 is located in the first space 111. In this way, it is equivalent to separating the electronic device 300 and the drive unit 230, which are easily damaged by humid fluids, from the components of the fluid pumping mechanism 200 that generate humid fluids. Thus, on the one hand, when the interface 120 cannot effectively discharge the humid fluid generated by the fluid pumping mechanism 200 to the external environment, the humid fluid retained in the main body chamber 110 cannot come into contact with the electronic device 300 and the drive unit 230, thereby preventing damage to the electronic device 300 and the drive unit 230. On the other hand, the electronic device 300 and the drive unit 230 are located in the same space, and the electronic device 300 and the drive unit 230 can be directly linearly connected without the need to set additional openings and sealing structures for the connection harness, thus reducing production costs.
[0061] Furthermore, as shown in Figures 12 and 13, the oral care device also includes a third housing 250 located within the first space 111. The third housing 250 is coupled to the first housing 213 or the second housing 214 and encloses a sealed third space 113. The electronic device 300 and the drive unit 230 are located in the third space 113. Thus, when moist fluid leaks from the second space 112, the sealing structure of the third space 113 can prevent the moist fluid from contacting the electronic device 300 and the drive unit 230, further avoiding the possibility of damage to the electronic device 300 and the drive unit 230 from the moist fluid.
[0062] In this embodiment, the outer surface of the whole formed by the third outer shell 250 and the shell component 210 surrounds the main shell 100 to form a fourth space 114. The fourth space 114 can surround the second space 112 and the third space 113, thereby making the second space 112 and the third space 113 form a visual effect similar to being suspended.
[0063] Correspondingly, when the aforementioned interface 120 is connected to the first space 111, the interface 120 can be connected to the fourth space 114. In this way, by setting the third space 113, damage can be avoided during the process of discharging the humid fluid to the external environment through the interface 120.
[0064] In practical applications, a first sealing element 216 is provided at the splicing surface of the first housing 213 and / or the second housing 214. Furthermore, the first housing 213 or the second housing 214 is provided with a first clearance hole 2131. The output end of the drive unit 230 extends through the first clearance hole 2131 to the transmission cavity 212. A second sealing element 217 is filled between the output end and the first clearance hole 2131. Thus, the first sealing element 216 and the second sealing element 217 isolate and seal the transmission cavity 212 from the first space 111, preventing humid fluid from leaking through the splicing surface of the first housing 213 and the second housing 214, or through the first clearance hole 2131, into the third space 113.
[0065] It is worth mentioning that in this embodiment, the first space 111 is divided into a third space 113 and a fourth space 114 that are isolated and sealed from each other. The inlet pipe connecting the water tank 600 for supplying liquid to the inlet of the execution chamber 211 can be placed in the fourth space 114. In this way, if the inlet pipe is accidentally damaged and wet fluid leaks out, the wet fluid can also be prevented from damaging the drive unit 230 and electronic device 300 located in the third space 113.
[0066] 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 310 in the third space 113, a button hole 251 also needs to be provided on the third housing 250, as shown in Figures 14 and 15. Correspondingly, the oral care device may also include a button seal 700, which is coupled to the PCB board 310 and seals the button hole 251, thereby preventing humid fluid in the second space 112 from leaking into the third space 113 through the button hole 251.
[0067] The above-mentioned improvement scheme is not only applicable to oral care equipment, but also to any other equipment with a fluid pumping mechanism.
[0068] Specifically, based on the same inventive concept, this application also provides a device with a fluid pumping mechanism, comprising a main housing 100, a fluid pumping mechanism 200, and electronic components 300. The main housing 100 has a sealed main chamber 110. The fluid pumping mechanism 200 is disposed within the main chamber 110 and includes a housing component 210. A first space 111 is formed between the outer surface of the housing component 210 and the main housing 100. The electronic components 300 are disposed within the first space 111. The main housing 100 has an interface 120, through which at least a portion of the space within the main chamber 110 communicates with the external environment, thereby allowing humid fluid within the main chamber 110 to be discharged to the external environment through the interface.
