[0032] Currently, oral care devices on the market mainly adopt three design methods to achieve oral irrigation function. The first method 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, which is responsible for delivering water flow to the water pick to generate water flow impact. The second method is to integrate the pump body in the water pick, so that the device can independently provide water flow impact without an additional liquid supply base station. The third method is a flushing all-in-one machine, which not only integrates the irrigation function, but also has the tooth brushing function, and also integrates the pump body inside to provide the required water flow impact. These designs have their own characteristics and meet the needs of different users and use scenarios, but all need to use a pump body to provide water flow impact.

[0033] However, the commonly used water pump, such as a piston pump, a diaphragm pump, etc., mainly extracts liquid through a stroke and extrudes it into the output pipeline, which will cause water vapor leakage in the process. Specifically, taking the piston pump as an example, the applicant has found through in-depth research that the pump body has a cylinder sleeve inside, and the piston reciprocates in the cylinder sleeve to suck and discharge liquid, and in this 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 devices such as the battery and circuit board 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 devices such as the battery and circuit board inside the oral care device.

[0034] The applicant has attempted to install two sealing rings on the piston to improve the sealing performance between the piston and the inner wall of the cylinder sleeve by increasing the number of sealing rings, thereby avoiding water leakage. However, this solution also increases the friction between the piston and the cylinder sleeve, which requires more power to drive the piston, and still cannot avoid the liquid adhering to the inner wall of the cylinder sleeve from evaporating and leaking.

[0035] The applicant has also attempted to set a concertina-shaped sealing sleeve between the outer wall of the cylinder sleeve or the outer wall of the pump housing and the connecting rod driving the piston to move, which uses the sealing sleeve to isolate the liquid adhering to the inner wall of the cylinder sleeve from the outside to avoid the liquid adhering to the inner wall of the cylinder sleeve from evaporating and spreading outward. Although this solution can prevent liquid and moisture from leaking, the sealing sleeve needs to move with the connecting rod, which is prone to damage and aging, has a low service life, and after damage and aging, it will still cause leakage and damage to the electronic devices.

[0036] To this end, the application proposes a new improved scheme, which avoids the damage of the electronic devices in the oral care device caused by the humid fluid by avoiding the entry of external humid fluid (liquid or water vapor) and guiding the internal leaked humid fluid to the outside. Specifically, by sealing the oral care device as a whole to achieve spatial isolation, the entry of the humid fluid outside the oral care device into the oral care device is avoided, and a through hole is arranged to communicate the internal space of the oral care device with the external environment, so that the leaked liquid and moisture in the internal space of the oral care device can be discharged in time through the through hole, thereby reducing the humidity in the internal space of the oral care device and avoiding damage to the electronic devices in the oral care device, and improving the service life.

[0037] To make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments.

[0038] Please refer to Figures 1 to 4 In an implementable embodiment, the oral care device can at least include a main shell 100, a fluid pumping mechanism 200 and electronic devices 300. The main shell 100 serves as a bearing component of the oral care device, mainly for supporting and protecting the remaining parts of the oral care device. Specifically, the main shell 100 has a main body cavity 110, the fluid pumping mechanism 200 is arranged in the main body cavity 110, and the fluid pumping mechanism 200 can extract liquid through the stroke and press it into the output pipeline to provide kinetic energy for the liquid to deliver the liquid. The fluid pumping mechanism 200 includes a shell component 210, the outer surface of the shell component 210 and the main shell 100 form a first space 111, and the electronic devices 300 are arranged in the first space 111. In this way, the shell component 210 can isolate the internal components of the fluid pumping mechanism 200 from the electronic devices 300 to some extent, avoiding the direct splashing of the leaked liquid in the fluid pumping mechanism 200 on the electronic devices 300, and playing a certain protective role.

[0039] At the same time, considering that the fluid pumping mechanism 200 located inside the main body cavity 110 can have a wet fluid leakage, which can still cause the wet fluid in the main body cavity 110 to increase, and damage the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300. Therefore, in the embodiment, the main shell 100 can be provided with an interaction port 120, and at least part of the space in the main body cavity 110 can be communicated with the external environment through the interaction port 120, so that the wet fluid in the main body cavity 110 can be discharged to the external environment through the interaction port 120, reducing the humidity inside the main body cavity 110, avoiding damage to the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300, and further improving the service life of the oral care device.

[0040] It should be noted that the interaction port 120 can not have a screening function, which not only allows the wet fluid in the main body cavity 110 to be discharged to the external environment, but also allows the dry gas in the main body cavity 110 to pass through the dry gas in the external environment. The oral care device refers to a device integrated with the fluid pumping mechanism 200 and used for oral care, which can include but is not limited to the combination of the oral irrigator and the liquid supply base station, the liquid supply base station in the combination design, the oral irrigator integrated with the fluid pumping mechanism, and the flushing all-in-one machine.

[0041] In actual application, the electronic device 300 can include but is not limited to one or more of a battery, a PCB board 310, a motor, and a display screen.

[0042] In addition to being communicated with the external environment through the interaction port 120, the rest of the main shell 100 can be sealed to isolate the main body cavity 110 from the external environment as much as possible, realize internal and external dry and wet isolation, avoid the moisture in the external environment entering the main body cavity 110 through the main shell 100, and thus aggravate the moisture in the main body cavity 110 and cause damage to the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300. According to different types of oral care devices, the way of forming a relatively sealed main body cavity 110 in the main shell 100 will also be different. Taking the oral care device as a liquid supply base station as an example, as shown in Figure 1 and Figure 2As shown, the main housing 100 can include a main body 101 having an upper opening and a lower opening, a lower cover 102 arranged at the lower opening of the main body 101, and an upper cover 103 arranged at the upper opening of the main body 101. The lower cover 102 and the upper cover 103 can be sealed by a sealing member or glue sealing with the main body 101 respectively, so that the main body 101, the lower cover 102 and the upper cover 103 jointly form a relatively sealed main cavity 110. The upper cover 103 can also be provided with an adjustment button, and the assembly gap between the adjustment button and the upper cover 103 also needs to be sealed to ensure the high sealing performance of the main cavity 110. Taking the oral care device as an example, the oral irrigator integrated with the fluid pumping mechanism 200, as shown, Figure 5 As shown, the main housing 100 of the oral irrigator forms a handle-shaped grip, and the main housing 100 can include at least a main body 101 having an upper opening and an upper cover 103 arranged at the upper opening of the main body 101. The upper cover 103 and the main body 101 are sealed by a sealing member or glue sealing, so that the main body 101 and the upper cover 103 jointly form a relatively sealed main cavity 110. The upper cover 103 can be provided with a plug connector for connecting a nozzle, and the assembly gap between the plug connector and the upper cover 103 also needs to be sealed to ensure the high sealing performance of the main cavity 110.

[0043] It is worth mentioning that the present application also seals the main cavity 110 to a certain extent by the main housing 100, realizes space isolation, and reduces the possibility of external humid fluid entering the main cavity 110. At the same time, by connecting at least part of the space in the main cavity 110 to the external environment through the interaction port 120, the humid fluid in the main cavity 110 is discharged to the external environment through the interaction port 120, the influence of internal and external humid fluid on the humidity in the main cavity 110 is comprehensively considered, so as to reduce the damage possibility of the internal and external humid fluid to the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300, reduce the content of the humid fluid in the main cavity 110 as much as possible, and provide the service life of the oral care device.

[0044] In practical applications, the interaction port 120 can be arranged at any position of the main shell 100, and can make the water vapor in the main cavity 110 discharged to the external environment. The interaction port 120 can be provided with a waterproof and breathable member, so as to block the liquid in the external environment from entering the main cavity 110 through the interaction port 120. In view of the fact that the liquid in the main cavity 110 can be discharged to the external environment and the external moist fluid is prevented from entering, the interaction port 120 can be arranged at the bottom of the main shell 100, for example, when the oral care device is a liquid supply base station, the interaction port 120 is arranged on the lower cover 102, so that when there is liquid in the main cavity 110, the liquid can flow out of the interaction port 120 under the action of gravity, and at the same time, the entry of the liquid in the external environment is also avoided. Of course, in order to facilitate the liquid in the main cavity 110 to flow to the interaction port 120 and flow out of the interaction port 120, a flow guide groove can also be arranged on the inner wall surface of the main shell 100 forming the main cavity 110, and the flow guide groove can guide the liquid in the main cavity 110 to flow to the interaction port 120.

[0045] Regarding the specific implementation mode that at least part of the space in the main cavity 110 is communicated with the external environment through the interaction port 120, so that the moist fluid in the main cavity 110 is discharged to the external environment through the interaction port 120, the present application provides two implementable embodiments for reference.

[0046] Embodiment one, as shown in Figure 3 and Figure 4 The fluid pumping mechanism 200 further includes an execution unit 220, a driving unit 230 and a transmission unit 240, and the shell member 210 at least has an execution cavity 211 and a transmission cavity 212, both of which are isolated and sealed from the first space 111, so as to prevent the moist fluid in the execution cavity 211 and the transmission cavity 212 from directly flowing into the first space 111. The execution unit 220 is located in the execution cavity 211, the transmission unit 240 is located in the transmission cavity 212 and partially extends into the execution cavity 211 to be connected with the execution unit 220. The output end of the driving unit 230 extends into the transmission cavity 212 and is connected with the execution unit 220 through the transmission unit 240, so that the driving unit 230 drives the execution unit 220 to move through the transmission unit 240, so as to suck the liquid from the inlet of the execution cavity 211 into the execution cavity 211 and discharge the liquid from the outlet of the execution cavity 211. In view of the fact that the moist fluid generated by the fluid pumping mechanism 200 mainly comes from the liquid leaked into the transmission cavity 212 and the water vapor evaporated into the transmission cavity 212, the interaction port 120 is communicated with the transmission cavity 212 in this embodiment, so that the moist fluid generated by the fluid pumping mechanism 200 is discharged from the interaction port 120 to the external environment through the transmission cavity 212.

[0047] Therefore, the embodiment can directly discharge the humid fluid from the source to the external environment, prevent the humid fluid from flowing into the first space 111, and avoid the humid fluid from damaging the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300. Meanwhile, even if the humid fluid in the external environment enters the interaction port 120, the humid fluid from the external environment can be prevented from entering the first space 111, and the driving unit 230 of the fluid pumping mechanism 200 and the electronic device 300 can be prevented from being damaged.

[0048] In actual applications, the fluid pumping mechanism 200 can be a piston pump, a diaphragm pump, or the like. Taking the piston pump as an example, the execution unit 220 is a piston, the driving 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. Therefore, the motor drives the transmission unit to convert the rotary motion into reciprocating motion, so as to drive the piston to reciprocate, extract, and pressurize and discharge the liquid. The oral care device usually further includes a water tank 600, which is arranged outside the main body cavity 110. The inlet of the execution cavity 211 can be communicated with the water tank 600 through a liquid inlet pipe, so as to avoid the water tank 600 from leaking the humid fluid to damage the driving unit 230 and the electronic device 300.

[0049] In an implementable embodiment, the shell component 210 is provided with a communication hole 218, which is communicated with the interaction port 120 through a pipeline 400, and has a component along the gravity direction. In this way, the humid fluid in the transmission cavity 212 is discharged to the external environment through the communication hole 218, the pipeline 400, and the interaction port 120 in sequence.

[0050] The shell component 210 has a part for surrounding the transmission cavity 212. The communication hole 218 is arranged at the bottom of the part of the shell component 210 along the gravity direction, and / or the interaction port 120 is arranged at the bottom of the main shell 100 along the gravity direction. In this way, the communication hole 218 and the interaction port 120 are both located at the lowest points of the corresponding parts, so that all the humid fluid in the transmission cavity 212 can be discharged as much as possible, and the damage possibility of the electronic device 300 and the driving unit 230 is reduced.

[0051] It should be noted that the gravity direction defined in the present application generally refers to the gravity direction in the conventional placement state of the oral care device, or can be understood as the gravity direction in the state that the bottom surface of the main shell 100 is placed horizontally.

[0052] Embodiment two, as Figure 1As shown, the aforementioned interface 120 can communicate with the first space 111. The humid fluid generated inside 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 inside the fluid pumping mechanism 200, or leaked liquid, will first enter the transmission chamber 212 of the fluid pumping mechanism 200, and then leak into the first space 111 through the transmission chamber 212, and then be discharged to the external environment from the first space 111 through the interface 120.

[0053] 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.

[0054] 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.

[0055] like Figure 3 As shown, in an 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figures 5 to 7 As shown, 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, dividing the second space 112 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.

[0061] Regarding the specific structure of the isolation and sealing between the transmission cavity 212 and the drive cavity 215, as follows: Figures 7 to 10 As shown, in one feasible embodiment, a first sealing member 216 is provided at the joint 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 joint surface of the first housing member 213 and the second housing member 214, or through the first clearance hole 2131.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] like Figure 11As shown, in another alternative embodiment, the housing component 210 comprises a first housing piece 213 and a second housing piece 214 coupled with each other, and a pump body 219, the first housing piece 213, the second housing piece 214 and the pump body 219 collectively enclose the second space 112 and divide the second space 112 into the execution cavity 211 and the transmission cavity 212, and the driving unit 230 of the fluid pumping mechanism 200 is located in the first space 111. In this way, the electronic device 300 and the driving unit 230 which are vulnerable to damage by the humid fluid are separated from the components of the fluid pumping mechanism 200 which generate the humid fluid, so that, on the one hand, when the interactive port 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 body cavity 110 cannot also contact the electronic device 300 and the driving unit 230 to cause damage to the electronic device 300 and the driving unit 230. On the other hand, the electronic device 300 and the driving unit 230 are located in the same space, and the electronic device 300 and the driving unit 230 can be directly linearly connected without the need to provide additional openings and sealing structures for the connection harness, thereby reducing production costs.

[0066] Further, as shown in FIG. 1, the oral care device further comprises a third housing piece 250 located in the first space 111, the third housing piece 250 is coupled with the first housing piece 213 or the second housing piece 214 and encloses a sealed third space 113, and the electronic device 300 and the driving unit 230 are located in the third space 113. In this way, when the humid fluid in the second space 112 leaks, the sealing structure of the third space 113 can block the humid fluid from contacting the electronic device 300 and the driving unit 230, further avoiding the possibility of damage to the electronic device 300 and the driving unit 230 by the humid fluid. Figure 12 Figure 13 As shown, in another alternative embodiment, the housing component 210 comprises a first housing piece 213 and a second housing piece 214 coupled with each other, and a pump body 219, the first housing piece 213, the second housing piece 214 and the pump body 219 collectively enclose the second space 112 and divide the second space 112 into the execution cavity 211 and the transmission cavity 212, and the driving unit 230 of the fluid pumping mechanism 200 is located in the first space 111. In this way, the electronic device 300 and the driving unit 230 which are vulnerable to damage by the humid fluid are separated from the components of the fluid pumping mechanism 200 which generate the humid fluid, so that, on the one hand, when the interactive port 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 body cavity 110 cannot also contact the electronic device 300 and the driving unit 230 to cause damage to the electronic device 300 and the driving unit 230. On the other hand, the electronic device 300 and the driving unit 230 are located in the same space, and the electronic device 300 and the driving unit 230 can be directly linearly connected without the need to provide additional openings and sealing structures for the connection harness, thereby reducing production costs.

[0067] In the present embodiment, the overall outer surface formed by the third housing piece 250 and the housing component 210 encloses a fourth space 114 with the main housing 100, and the fourth space 114 can surround the second space 112 and the third space 113, so that the second space 112 and the third space 113 form a similar suspended visual effect.

[0068] Correspondingly, when the above-mentioned interactive port 120 communicates with the first space 111, the interactive port 120 can communicate with the fourth space 114, so that by providing the third space 113, the humid fluid can be prevented from being damaged during the process of being discharged to the external environment through the interactive port 120.

[0069] ​In practical applications, the splicing surface of the first housing member 213 and / or the second housing member 214 is provided with a first sealing member 216. In addition, the first housing member 213 or the second housing member 214 is provided with a first accommodating hole 2131, and the output end of the driving unit 230 extends to the transmission cavity 212 through the first accommodating hole 2131, and the second sealing member 217 is filled between the output end and the first accommodating hole 2131, so as to isolate and seal the transmission cavity 212 from the first space 111 by using the first sealing member 216 and the second sealing member 217, thereby avoiding the leakage of the humid fluid to the third space 113 through the splicing surface of the first housing member 213 and the second housing member 214, or through the first accommodating hole 2131.

[0070] It is worth mentioning that the first space 111 is divided into the third space 113 and the fourth space 114 which are isolated and sealed from each other in the embodiment, and the liquid inlet pipe for connecting the water tank 600 for supplying liquid to the inlet of the execution cavity 211 can be arranged in the fourth space 114, so that when the liquid inlet pipe is accidentally damaged and the humid fluid leaks, the humid fluid can also avoid damaging the driving unit 230 and the electronic device 300 located in the third space 113.

[0071] Considering that the control button also needs to be arranged on the main shell 100 of the oral care device, the control button needs to be pressed and contacted with the button on the PCB 310 in the third space 113, therefore, the third housing member 250 also needs to be provided with a button hole 251. Correspondingly, the oral care device can also include a button sealing member 700, the button sealing member 700 is coupled with the PCB 310, and the button sealing member 700 seals the button hole 251, so as to avoid the humid fluid in the second space 112 from leaking into the third space 113 through the button hole 251.
