Description

Technical Field

[0001] This application relates to the technical field of oral care devices, and particularly to an oral care device. Background Art

[0002] With the progress of society, users pay more and more attention to oral hygiene, and oral care devices have gradually entered thousands of households.

[0003] In related technologies, an oral care device includes a water tank and a body. The body and the water tank are arranged vertically. The internal capacity of the water tank is generally small, so when users use the clean water in the water tank for oral care, they need to repeatedly add water to the water tank, which is very troublesome. However, if the volume of the water tank is designed too large, it is not conducive to users holding the oral care device for rinsing operations. Utility Model Content

[0004] An embodiment of this application provides an oral care device, which can make the single - time capacity of the water tank meet the basic cleaning requirements, and at the same time can take into account the portability and use convenience of the oral care device.

[0005] An embodiment of this application provides an oral care device, which includes:

[0006] A body, including a nozzle and a main body, the nozzle is connected to the main body; and

[0007] A water tank, the water tank includes a first accommodating part and a second accommodating part. The second accommodating part is located on one side of the first accommodating part along the length direction of the main body, and the inside of the first accommodating part and the inside of the second accommodating part are communicated to form a water storage cavity. The water storage cavity is used to communicate with the main body to supply water to the nozzle. The main body is supported and fixed on the surface of the first accommodating part close to the second accommodating part, and at least part of the second accommodating part is located on one side of the width direction of the main body;

[0008] Wherein, in the length direction of the main body, the length value of the first accommodating part is not greater than the length value of the main body.

[0009] Based on the above - mentioned embodiment, by dividing the water tank into a first accommodating part and a second accommodating part, the second accommodating part is located on one side of the first accommodating part along the length direction of the main body, and the main body is supported and fixed on the surface of the first accommodating part close to the second accommodating part. Such a layout greatly increases the total volume of the water tank, thereby increasing the amount of water used at one time, reducing the frequency of frequent water addition by users during use, and improving the convenience of use. At the same time, since the water tank is distributed on both sides of the main body rather than only on a single side of the main body, it avoids the problem that the overall product becomes too large and inconvenient to carry due to the increase in the volume of the water tank in traditional designs, and maintains the portability of the oral care device.

[0010] In some of these embodiments, the second accommodating portion and the main body are arranged side by side, and the second accommodating portion abuts against the surface of the main body along the width direction.

[0011] Based on the above embodiments, through the physical contact between the second accommodating portion and the main body, a firm connection between the two is achieved, effectively avoiding loosening or displacement caused by vibration or external forces.

[0012] In some of these embodiments, in the length direction of the main body, the cross-sectional area at any position of the second accommodating portion is greater than or equal to the cross-sectional area of the main body.

[0013] Based on the above embodiments, by increasing the capacity in a manner of lateral expansion rather than longitudinal stacking, the power consumption of the oral care device is reduced, and the energy utilization efficiency is improved.

[0014] In some of these embodiments, in the length direction of the main body, the cross-sectional area at any position of the second accommodating portion is smaller than the cross-sectional area of the main body.

[0015] Based on the above embodiments, by reducing the cross-sectional area of the second accommodating portion, the center of gravity of the oral care device is adjusted to the center position of the overall structure, so as to improve the use stability and convenience of the oral care device.

[0016] In some of these embodiments, the second accommodating portion is arranged around the circumferential side of the main body;

[0017] Or, the main body is arranged around the circumferential side of the second accommodating portion.

[0018] Based on the above embodiments, the wrap-around design also helps to optimize the spatial layout of the oral care device, enabling each component to be arranged more compactly, thereby improving the functionality and practicality of the product without increasing the overall volume.

[0019] In some of these embodiments, the oral care device further includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the main body, and the second connecting portion is connected to at least one of the first accommodating portion and the second accommodating portion. The first connecting portion and the second connecting portion are detachably connected, so that the water tank as a whole can be detached relative to the main body.

[0020] Based on the above embodiments, the water tank can be regularly detached for thorough cleaning, effectively preventing bacteria from growing and ensuring oral health, so as to facilitate the maintenance and upkeep of the oral care device.

[0021] In some embodiments, the connection method between the first connection part and the second connection part includes at least one of a snap connection, a screw connection and a magnetic connection.

[0022] Based on the above embodiments, a variety of detachable methods are provided to facilitate installation and removal of the first connection portion and the second connection portion.

[0023] In some embodiments, the first connection portion is one of a slider and a guide rail slidably matched with the slider, and the second connection portion is the other of the slider and the guide rail.

[0024] Based on the above embodiments, the connection process between the first connection part and the second connection part is simplified, the accuracy and durability of the connection are improved, and a more convenient and reliable connection is provided for the assembly of the oral care device.

[0025] In some embodiments, the first connection portion is disposed on a surface of the host close to the first accommodation portion, and the second connection portion is disposed on a surface of the first accommodation portion close to the second accommodation portion; or,

[0026] The first connection portion is disposed on a surface of the host close to the second accommodation portion, and the second connection portion is connected to a surface of the second accommodation portion facing the host.

[0027] Based on the above embodiment, the connection position is made closer to the center of gravity, so that the two can fit tightly when connected, reducing the problem of unstable connection caused by position deviation or looseness.

[0028] In some embodiments, the oral care device further comprises a control button, and the control button is disposed on at least one side wall of the host.

[0029] Based on the above embodiments, the control buttons can control the switch, water flow intensity, mode switching, etc. of the oral care device, so as to more flexibly respond to different cleaning needs.

[0030] In some embodiments, in the width direction of the host, the control button is arranged on a side of the host away from the first connecting portion.

[0031] Based on the above embodiments, when the user operates the oral care device by hand, the user can naturally and easily reach the control buttons without making cumbersome adjustments or changing the holding posture.

[0032] In some embodiments, in the width direction of the host, the orthographic projection of the control button, the orthographic projection of the first connecting portion, and the orthographic projection of the second connecting portion at least partially overlap.

[0033] Based on the above embodiments, the natural pressure generated when the user holds the device is utilized in this way, further stabilizing the connection structure between the first connecting portion and the second connecting portion.

[0034] In some of the embodiments, the main body includes a housing, and a motor, a pump body, and a circuit board disposed within the housing. The pump body communicates with the first receiving portion and / or the second receiving portion for pumping the liquid in the water storage chamber. The circuit board is connected to the pump body, and the motor is connected to the pump body;

[0035] Wherein, the motor, the pump body, and the circuit board are arranged along the length direction.

[0036] Based on the above embodiments, through the layout along the length direction, the lateral dimension of the main body is effectively reduced, making the entire oral care device thinner, more compact, and facilitating the user to easily hold and operate.

[0037] In some of the embodiments, the oral care device includes a water inlet pipe. A communication opening communicating with the water storage chamber is formed in the first receiving portion or the second receiving portion. The communication opening is in butt joint communication with the main body. One end of the water inlet pipe communicates with the communication opening, and the other end of the water inlet pipe extends to the bottom of the water storage chamber.

[0038] Based on the above embodiments, through the guiding action of the water inlet pipe, the oral care device can ensure that when needed, the liquid in the water storage chamber can quickly and smoothly flow into the main body, providing sufficient water source for subsequent cleaning work.

[0039] In some of the embodiments, the water inlet pipe is a flexible pipe, and the length value of the first receiving portion in the length direction of the main body is less than the length value of the water inlet pipe when unfolded in the length direction.

[0040] Based on the above embodiments, the flexible pipe material of the water inlet pipe enables it to be easily deformed, so as to be able to flexibly adapt to various use angles and postures. At the same time, the water inlet pipe can be laterally unfolded at the first receiving portion to extend to the position where the first receiving portion receives the main body, thereby ensuring that even when the oral care device is in an inclined state, the water at the receiving portion of the first receiving portion can be effectively prevented from accumulating due to the action of gravity, thus maintaining the smooth discharge of water flow.

[0041] In some of the embodiments, the water inlet pipe is a flexible pipe, and the oral care device further includes a counterweight, and the counterweight is connected to the end of the water inlet pipe far from the communication opening.

[0042] Based on the above embodiments, the presence of the counterweight provides additional weight and stability to the water inlet pipe, enabling the water inlet pipe to more easily deform towards the position where the first receiving portion receives the main body under the action of external force or at different use angles.

[0043] In some of these embodiments, the oral care device further includes an end cap. An injection port is provided on a side of the second accommodation portion facing away from the first accommodation portion. The injection port is in communication with the water storage chamber. The end cap is movably connected to the second accommodation portion to cover or uncover the injection port.

[0044] Based on the above embodiments, through the flexible operation of the end cap, the user can replenish the water source for the oral care device at any time and place, without worrying about the tediousness and inconvenience during the water filling process.

[0045] In some of these embodiments, a gripping portion is provided on a side of the water tank facing away from the main body. The gripping portion is for the user to grip.

[0046] Based on the above embodiments, through the gripping portion, the user can achieve a stable grip. Even if there is a slight movement or angle adjustment during the operation, the stability of the oral care device in the user's hand can be ensured, avoiding the inconvenience or accident caused by slipping.

[0047] For the oral care device based on the embodiments of the present application, by dividing the water tank into a first accommodation portion and a second accommodation portion, the second accommodation portion is located on one side of the first accommodation portion along the length direction of the main body, and the main body is supported and fixed on the surface of the first accommodation portion close to the second accommodation portion. Such a layout greatly increases the overall volume of the water tank, thereby increasing the amount of water used in a single use, reducing the frequency of frequent water filling by the user during the use process, and improving the convenience of use. At the same time, since the water tank is distributed on both sides of the main body rather than only on a single side of the main body, it avoids the problem that the overall product becomes too large and inconvenient to carry due to the increase in the volume of the water tank in the traditional design, and maintains the portability of the oral care device.

[0048] In addition, by restricting the length of the first accommodation portion to be not greater than the length of the main body, it is ensured that the overall center of gravity of the oral care device after water filling will not shift excessively, avoiding the operation inconvenience or tipping risk caused by an unstable center of gravity, and improving the use stability and safety of the oral care device. At the same time, it effectively reduces the redundancy of the water flow path, can reduce the energy consumption during water supply to a certain extent, and improves the energy utilization efficiency.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0063] The embodiments of the present application provide an oral care device, and the oral care device includes, but is not limited to, an electric toothbrush, a dental irrigator, an oral examination device, etc.

[0064] In the related art, the oral care device includes a water tank and a body, and the body and the water tank are arranged vertically. The internal capacity of the water tank is generally small, resulting in the need for the user to repeatedly add water to the water tank when flushing the teeth with the clear water in the water tank, which is very troublesome. However, if the volume of the water tank is designed too large, it is not conducive to the user to hold the oral care device for flushing operation.

[0065] To solve the above problems, please refer to Figures 1 to 3 This application proposes an oral care device 100. In the embodiments of the present application, the oral care device 100 includes a body 10 and a water tank 20. The following will take the oral care device as a dental irrigator for detailed description. The dental irrigator flushes the user's oral cavity, especially the user's teeth, by spraying pulsed water columns.

[0066] The body 10 includes a nozzle 11 and a main body 12, and the nozzle 11 is connected to the main body 12. Among them, the main body 12 serves as the power part in the oral care device 100. The outer contour of the main body 12 can be arranged in a long strip shape, which not only optimizes the space layout, facilitates installation and use in various scenarios, but also enhances the overall aesthetics. The nozzle 11 can be connected to the main body 12 by means of screws or buckles. This modular design enables users to easily and quickly complete the operation when the nozzle 11 is worn or different specifications of the nozzle 11 need to be replaced, without the need for professional tools, greatly reducing the maintenance cost and time. And when the nozzle 11 is connected to the main body 12, the nozzle 11 is in communication with the water supply flow path in the main body 12 to enable the nozzle 11 to eject water flow.

[0067] The water tank 20 includes a first accommodating part 21 and a second accommodating part 22. The inside of the first accommodating part 21 and the inside of the second accommodating part 22 are in communication to form a water storage cavity 20A. The water storage cavity 20A is not only used to store the liquid required for cleaning (such as water or a mixture of water and other substances), but also connected to the water supply flow path of the main body 12 to ensure that the nozzle 11 can continuously obtain a stable water flow supply, thereby improving the use efficiency and cleaning effect of the oral care device 100.

[0068] The second accommodating part 22 is located on one side of the first accommodating part 21 along the length direction of the main body 12. The main body 12 is supported and fixed on the surface of the first accommodating part 21 close to the second accommodating part 22, and at least part of the second accommodating part 22 is located on one side of the width direction of the main body 12. Such a layout not only optimizes the compactness of the overall structure, but also enhances the stability and durability of the oral care device 100. Among them, in the length direction of the main body 12, the length value of the first accommodating part 21 is not greater than the length value of the main body 12. So that the outer contour of the entire water tank 20 can be arranged in an "L" shape or a "convex" shape, which not only optimizes the space layout, but also enhances the practicality and aesthetics of the design. It should be noted that the first accommodating part 21 and the second accommodating part 22 can be either an integral structure to ensure the overall stability and durability of the water tank 20. At the same time, both also support a detachable splicing design scheme. This flexibility provides great convenience for users, enables the inside of the water storage cavity 20A to be easily and deeply cleaned, effectively prevents bacteria from breeding, and ensures the hygiene and safety of use.

[0069] Based on the oral care device 100 of the embodiments of the present application, by dividing the water tank 20 into a first accommodating portion 21 and a second accommodating portion 22, the second accommodating portion 22 is located on one side of the first accommodating portion 21 along the length direction of the main body 12, and the main body 12 is supported and fixed on the surface of the first accommodating portion 21 close to the second accommodating portion 22. Such a layout greatly increases the overall volume of the water tank 20, thereby increasing the amount of water used per single use, reducing the frequency of frequent water addition by the user during use, and enhancing the convenience of use. At the same time, since the water tank 20 is distributed on both sides of the main body 12 instead of only on a single side of the main body, it avoids the problem that the overall product becomes too large and inconvenient to carry due to the increase in the volume of the water tank 20 in the traditional design, and maintains the portability of the oral care device 100.

[0070] In addition, by restricting the length of the first accommodating portion 21 to be not greater than the length of the main body 12, it is ensured that the overall center of gravity of the oral care device 100 after water addition will not shift excessively, avoiding the inconvenience in operation or the risk of tipping caused by unstable center of gravity, and improving the use stability and safety of the oral care device 100. At the same time, it effectively reduces the redundancy of the water flow path, can reduce the energy consumption during water supply to a certain extent, and improves the energy utilization efficiency.

[0071] In some embodiments, a holding portion is provided on the surface of the water tank 20 facing away from the main body 12. In this way, through the holding portion, the user can achieve a firm grip. Even if there is a slight movement or angle adjustment during operation, it can ensure the stability of the oral care device 100 in the user's hand, avoiding the inconvenience or accident caused by slipping. It can be understood that the holding portion can be a concave structure to increase the finger fit, or a frosted or convex structure to enhance the holding feeling and anti-slip performance, making the oral care process smoother and safer.

[0072] Refer to Figures 2 to 4 In some structural forms of the arrangement of the second accommodating portion 22 and the main body 12, the second accommodating portion 22 and the main body 12 are arranged side by side, and the second accommodating portion 22 abuts against the surface of the main body 12 along the width direction. This not only optimizes the space utilization, but also significantly enhances the overall stability of the oral care device 100. The second accommodating portion 22 closely adheres to the surface of the main body 12 along the width direction, and through direct physical contact, a firm connection between the two is achieved, effectively avoiding loosening or displacement caused by vibration or external force.

[0073] Furthermore, in the longitudinal direction of the main body 12, the cross-sectional area at any position of the second accommodating portion 22 is greater than or equal to the cross-sectional area of the main body 12. In this way, by increasing the cross-sectional area of the second accommodating portion 22, the problem of excessive increase in the length of the water tank 20 is effectively avoided. In traditional designs, to achieve the same capacity, it is often necessary to increase the length of the water tank 20, which may also lead to an increase in the lengths of the first accommodating portion 21 and the second accommodating portion 22 (assuming the overall shape of the water tank 20 is close to an L shape). The increase in length not only affects the overall aesthetics of the oral care device 100, but also because the water tank 20 with an excessive length requires a stronger pump power to overcome gravity and deliver the liquid to the nozzle 11. However, this design increases the capacity by expanding laterally instead of stacking longitudinally, effectively solving this problem, reducing the power consumption of the oral care device 100, and improving the energy utilization efficiency.

[0074] In another embodiment, in the longitudinal direction of the main body 12, the cross-sectional area at any position of the second accommodating portion 22 is smaller than the cross-sectional area of the main body 12. Specifically, in this way, by reducing the cross-sectional area of the second accommodating portion 22, the center of gravity of the oral care device 100 is adjusted to the center position of the overall structure. This adjustment is crucial for improving the stability and usability of the oral care device 100. When the oral care device 100 is in the working state, the center of gravity located at the center position can ensure that the device remains balanced during operation, reducing the possibility of shaking and tilting, thereby improving the cleaning effect and user experience. In addition, the center of gravity located at the center position also helps to firmly fix the oral care device 100 in the left-right direction, reducing the phenomenon of falling off or loosening caused by external forces. This design detail not only enhances the safety and reliability of the oral care device 100, but also provides a more convenient and comfortable user experience.

[0075] In some other structural forms of the arrangement of the second accommodating portion 22 and the main body 12, the second accommodating portion 22 is disposed around the circumferential side of the main body 12. In this way, by surrounding the circumferential side of the main body 12, the second accommodating portion 22 not only provides additional protection and support for the main body 12, but also enhances the stability and durability of the overall structure. In addition, this surrounding design also helps to optimize the internal space layout of the oral care device 100, enabling each component to be arranged more compactly, thereby improving the functionality and practicality of the product without increasing the overall volume.

[0076] In some other structural forms of the arrangement of the second accommodating portion 22 and the main body 12, the main body 12 is disposed around the circumferential side of the second accommodating portion 22. In this way, the layout of the main body 12 around the second accommodating portion 22 makes the overall structure more compact, effectively utilizes the space, reduces the overall size of the device, and facilitates carrying and storage. At the same time, this design also enhances the structural stability of the device. As the core component, the surrounding arrangement of the main body 12 provides a solid support for the second accommodating portion 22, reducing the risk of deformation or damage caused by external forces.

[0077] Referring to Figures 2 to 4 , in some embodiments, the oral care device 100 further includes a first connecting portion 30 and a second connecting portion 40. The first connecting portion 30 is connected to the main body 12, and the second connecting portion 40 is connected to at least one of the first accommodating portion 21 and the second accommodating portion 22. Among them, the second connecting portion 40 is flexibly connected to the first accommodating portion 21 or the second accommodating portion 22, and may even be connected to both at the same time. The first connecting portion 30 and the second connecting portion 40 are detachably connected so that the water tank 20 as a whole can be detached relative to the main body 12. In this way, not only can the water tank 20 be regularly detached for thorough cleaning, effectively preventing the growth of bacteria and ensuring oral health, which is convenient for the maintenance and upkeep of the oral care device 100, but also different specifications or functions of the water tank 20 can be replaced according to actual needs to meet personalized usage requirements.

[0078] Furthermore, the connection manner between the first connecting portion 30 and the second connecting portion 40 includes at least one of snap connection, screw connection, and magnetic attraction connection. Among them, the snap connection ensures the firmness and rapidity of the connection between the first connecting portion 30 and the second connecting portion 40. In this way, only simple operations are required for connection and separation during subsequent use, greatly improving the operational convenience. For example, the first connecting portion 30 is a buckle, and the second connecting portion 40 is a slot, and the water tank 20 and the main body 12 can be relatively connected through the snap-fit of the buckle and the slot. The screw connection provides higher connection strength and sealing performance, so that the oral care device 100 has higher stability and usage safety, ensuring the normal operation of the oral care device 100. For example, threaded holes are provided in both the first connecting portion 30 and the second connecting portion 40, and the water tank 20 and the main body 12 can also be relatively connected by passing and fixing screws through the threaded holes. The magnetic attraction connection realizes seamless docking and rapid response of the connection, simplifying the disassembly operation process. Specifically, the first connecting portion 30 is a magnetic component, and the second connecting portion 40 is made of a metal material or is a magnetic component. Simply approaching the first connecting portion 30 and the second connecting portion 40 can achieve automatic adsorption, greatly simplifying the steps of disassembly and installation.

[0079] Optionally, the first connecting portion 30 is one of a slider (not shown) and a guide rail (not shown) that slidably cooperates with the slider, and the second connecting portion 40 is the other of the slider and the guide rail. Thus, when the first connecting portion 30 is the slider, it can slide smoothly along the guide rail of the second connecting portion 40, achieving precise and stable connection and positioning, and increasing the flexibility and adaptability of the connection. Conversely, if the first connecting portion 30 is the guide rail, the slider of the second connecting portion 40 can slide along it, also ensuring smooth and firm connection. This mutually cooperative design not only simplifies the connection process of the first connecting portion 30 and the second connecting portion 40, but also improves the connection accuracy and durability, bringing a more convenient and reliable connection experience for the assembly of the oral care device 100.

[0080] Optionally, the first connecting portion 30 is disposed on the surface of the main body 12 close to the first accommodating portion 21, and the second connecting portion 40 is disposed on the surface of the first accommodating portion 21 close to the second accommodating portion 22. By disposing the second connecting portion 40 on one side of the first accommodating portion 21 close to the second accommodating portion 22, the connection position is closer to the center of gravity, enabling the two to fit tightly when connected, reducing the problem of unstable connection caused by position deviation or looseness, and thus ensuring the stability and reliability of the oral care device 100 during use to improve the comfortable use experience.

[0081] Referring to Figures 2 to 4 , in another setting manner, the first connecting portion 30 is disposed on the surface of the main body 12 close to the second accommodating portion 22, and the second connecting portion 40 is connected to the surface of the second accommodating portion 22 facing the main body 12. In this way, the connection process between the water tank 20 and the main body 12 can be installed along the length direction, greatly improving the convenience and flexibility of installation. Users can easily achieve a tight connection between the two without complicated turning or adjustment, thus simplifying the operation process and improving the use efficiency.

[0082] Referring to Figures 2 to 4 , in some structural forms, the oral care device further includes control buttons, and the control buttons are disposed on at least one side wall of the main body. It can be understood that the control buttons 13 are electrically connected to the main body 12, so that the control buttons 13 can control the switch, water flow intensity, mode switching, etc. of the oral care device 100, thus more flexibly meeting different cleaning requirements.

[0083] Further, in the width direction of the main body 12, the control button 13 is disposed on a side of the main body 12 away from the first connection portion 30. In this way, when the user holds the oral care device 100 for operation, the control button 13 can be naturally and easily touched without cumbersome adjustment or change of the holding posture. Further, in the width direction of the main body 12, at least a part of the orthographic projection of the control button 13 coincides with the orthographic projections of the first connection portion 30 and the second connection portion 40. Specifically, due to this layout relationship of the control button 13, the first connection portion 30, and the second connection portion 40 in the width direction, when the user holds the oral care device 100, the connection position of the first connection portion 30 and the second connection portion 40 is exactly within the palm coverage range on the opposite side of the control button 13. This design cleverly utilizes the natural pressure generated when the user holds the device, further stabilizing the connection structure on both sides and effectively avoiding the potential separation risk between the main body 12 and the water tank 20 due to the increased volume of the water tank 20. Therefore, this layout improves the overall structural stability and reliability of the oral care device 100 and also ensures comfort and safety during use.

[0084] In some structural forms, with reference to Figures 2 to 4 , the main body 12 includes a housing 121 and a motor 122, a pump body 123, and a circuit board 124 disposed inside the housing 121. The pump body 123 is in communication with the first receiving portion 21 and the second receiving portion 22 for pumping the liquid in the water storage cavity 20A. The circuit board 124 is connected to the pump body 123, and the motor 122 is connected to the pump body 123. Among them, the length direction of the main body 12 is actually the length direction of the housing 121 of the main body 12, and the outer contour of the housing 121 can be set in a rectangular parallelepiped shape. The motor 122, the pump body 123, and the circuit board 124 are installed inside the housing 121 and are isolated from the water tank 20 through the housing 121. The nozzle 11 is fixed to the housing 121 and at least partially exposed outside the housing 121. The motor 122 serves as a power source and directly drives the pump body 123 to work, and the pump body 123 is in communication with at least one of the first receiving portion 21 and the second receiving portion 22, effectively realizing the liquid transmission from the water storage cavity 20A to the nozzle 11. The circuit board 124 serves as a control center, precisely regulating the operating state of the entire system to ensure that the oral care device 100 can operate stably according to the preset program. At the same time, the main body 12 is also provided with a battery (not shown), and the battery can be used to supply power to the water pump and the motor 122.

[0085] In addition, the motor 122, the pump body 123, and the circuit board 124 are arranged along the length direction, that is, the length directions of the motor 122, the pump body 123, and the circuit board 124 are the same as the length direction of the housing 121. Through the layout along the length direction, the lateral dimension of the main unit 12 is effectively reduced, making the entire oral care device 100 thinner, more compact, and easier for users to hold and operate. It avoids the inconvenience of holding or hand fatigue caused by the over-wide main unit 12. At the same time, the compact body 10 is also convenient for carrying and storage.

[0086] With reference to Figure 2 , in some structural forms, the oral care device 100 includes a water inlet pipe 50. A communication opening 20a communicating with the water storage cavity 20A is provided in the first accommodation part 21 or the second accommodation part 22. The communication opening 20a is docked and communicated with the main unit 12. One end of the water inlet pipe 50 is communicated with the communication opening 20a, and the other end of the water inlet pipe 50 extends to the bottom of the water storage cavity 20A. Specifically, a communication opening 20a communicating with the water storage cavity 20A is provided on the first accommodation part 21 or the second accommodation part 22 of the oral care device 100. Specifically, the communication opening 20a can be provided on the surface of the second accommodation part 22 facing the main unit 12. With reference to Figure 5 as shown, or the communication opening 20a is on the surface of the first accommodation part 21 facing the main unit 12. With reference to Figure 6 as shown. This design forms a direct and efficient connection channel between the water storage cavity 20A and the main unit 12. As an important medium of this connection channel, one end of the water inlet pipe 50 is tightly connected to the communication opening 20a to ensure seamless butt-joint of the water flow. The other end extends to the bottom of the water storage cavity 20A skillfully to realize the guidance of the liquid in the water storage cavity 20A. Through the guiding function of the water inlet pipe 50, the oral care device 100 can ensure that when needed, the liquid in the water storage cavity 20A can flow into the main unit 12 quickly and smoothly, providing sufficient water source for subsequent cleaning work. At the same time, the extended design of the water inlet pipe 50 also effectively avoids waste and residue of the liquid in the water storage cavity 20A.

[0087] Furthermore, the water inlet pipe 50 is a flexible hose, and the length value of the first accommodating portion 21 in the longitudinal direction of the main body 12 is less than the length value of the water inlet pipe 50 when it is unfolded in the longitudinal direction. Herein, the flexible hose material of the water inlet pipe 50 enables it to be easily deformed, so as to be able to flexibly adapt to various use angles and postures. At the same time, the design that the length of the first accommodating portion 21 is less than the unfolded length of the water inlet pipe 50 allows the water inlet pipe 50 to be laterally unfolded in the first accommodating portion 21 to extend to the position where the first accommodating portion 21 receives the main body 12. Thus, even when the oral care device 100 is in an inclined state, it can effectively prevent the water at the receiving portion of the first accommodating portion 21 from accumulating due to gravity, thereby maintaining the smooth discharge of the water flow. At the same time, since the water inlet pipe 50 has sufficient extensibility, it can be more flexibly adjusted and optimized during assembly, which helps to simplify the production process flow and improve the forming accuracy and efficiency.

[0088] Optionally, the oral care device 100 further includes a counterweight (not shown), and the counterweight is connected to one end of the water inlet pipe 50 away from the communication opening 20a. Herein, the presence of the counterweight provides additional weight and stability to the water inlet pipe 50, enabling the water inlet pipe 50 to be more easily deformed towards the position where the first accommodating portion 21 receives the main body 12 when subjected to an external force or at different use angles. This deformation not only helps to adapt to different use requirements but also ensures the smooth flow of the water, reducing the possibility of water flow being blocked or accumulated. It should be noted that the counterweight can be provided in a block or spherical structure. The counterweight can be made of a metal material such as aluminum alloy, which not only has sufficient weight but also has good corrosion resistance and stability, ensuring that the counterweight maintains stable performance during long-term use.

[0089] Refer to Figure 3 and Figure 4, in some structural forms, the oral care device 100 further includes an end cap 60. A water injection port 22a is provided on the side of the second accommodating portion 22 facing away from the first accommodating portion 21. The water injection port 22a is communicated with the water storage cavity 20A. The end cap 60 is movably connected to the second accommodating portion 22 to cover or uncover the water injection port 22a. Among them, an activity connection method is adopted between the end cap 60 and the second accommodating portion 22. This design enables the end cap 60 to easily switch between the covered state and the uncovered state. When the user needs to inject clean water into the oral care device 100, simply open the end cap 60, and the clean water can be injected into the water storage cavity 20A through the water injection port 22a. After the water addition is completed, the user can quickly cover the end cap 60 to ensure the sealing performance of the water injection port 22a, prevent water evaporation or the entry of external pollutants. This design not only improves the usability of the oral care device 100, but also enhances its overall safety and hygiene. Through the flexible operation of the end cap 60, the user can replenish the water source of the oral care device 100 at any time without worrying about the cumbersome and inconvenient water addition process. At the same time, the sealing performance of the end cap 60 also effectively guarantees the purity and cleanliness of the water quality inside the oral care device 100, improving the user experience.
