[0040] With the improvement of living standards, people pay more and more attention to oral hygiene. At present, various oral cleaning tools are launched on the market, among which the electric toothbrush has received the best response. The electric toothbrush uses the rapid rotation or vibration of its electric motor to drive the brush head to produce high-frequency vibration, which can not only instantly break down the toothpaste into fine foam and deeply clean the gaps between teeth, but also the vibration of the brush head can promote blood circulation in the mouth and massage the gum tissue. Compared with traditional manual toothbrushes, the brush head of electric toothbrushes vibrates at a speed of thousands or even tens of thousands of times per minute, and the brushing efficiency is much higher than that of manual toothbrushes.

[0041] However, in the related technical field, electric toothbrushes that can automatically supply toothpaste can only be used by users with designated toothpaste, which is very restrictive.

[0042] The utility model provides an electric toothbrush.

[0043] In the utility model embodiment, refer to Figures 1 to 3The electric toothbrush 10 includes a toothbrush body 100, a container 200 and an extrusion mechanism 300. The toothbrush body 100 has a brush head end 110 and a gripping end 120 that are arranged opposite to each other. The brush head end 110 is provided with an extrusion port 111, and the gripping end 120 is provided with a mounting cavity 130 that is communicated with the extrusion port 111; the container 200 is detachably installed in the mounting cavity 130, and the container 200 has a housing cavity 210 for containing an oral cleaning agent 20, and a first opening 220 and a second opening 230 that are communicated with the housing cavity 210. The first opening 220 is communicated with the extrusion port 111 through the mounting cavity 130, and the second opening 230 is used to add the oral cleaning agent 20; the extrusion mechanism 300 is arranged in the mounting cavity 130, and the extrusion mechanism 300 is detachably connected to the container 200, and the extrusion mechanism 300 is suitable for squeezing the oral cleaning agent 20 in the housing cavity 210 toward the extrusion port 111.

[0044] The toothbrush body 100 is the main structure of the electric toothbrush 10, which is responsible for supporting other components and providing a grip for the user. The extrusion port 111 of the brush head end 110 is designed so that the oral cleaner 20 can flow out smoothly and be evenly applied to the bristles. The mounting cavity 130 of the grip end 120 is designed to accommodate the container 200 and the extrusion mechanism 300, thereby achieving a compact overall structure.

[0045] Optionally, the toothbrush body 100 can be made of different materials and colors to meet the aesthetic and comfort requirements of different users. The shape and size of the mounting cavity 130 can be adjusted to accommodate different shapes and sizes of the receiving member 200 and the extrusion mechanism 300. The grip end 120 can be textured or rubber-wrapped to improve the stability of the user's grip.

[0046] The container 200 serves as a storage container for the oral cleaner 20 and has sufficient capacity to store the cleaner for multiple uses. The first opening 220 is connected to the mounting cavity 130 and the extrusion port 111 to ensure that the oral cleaner 20 can flow smoothly. The second opening 230 facilitates the user to add or replace the oral cleaner 20, thereby improving the convenience of use. The first opening 220 and the second opening 230 can be provided on the same side or different sides of the container 200 at the same time, without any special limitation.

[0047] In some embodiments, the first opening 220 and the second opening 230 may be the same opening.

[0048] Optionally, the container 200 can be made of a transparent or translucent material to facilitate the user to observe the remaining amount of detergent. A scale line or a capacity mark is set on the container 200 to help the user more accurately grasp the amount of detergent added. The second opening 230 can be designed as a detachable cover or plug to increase the sealing and prevent the detergent from leaking.

[0049] The extrusion mechanism 300 is responsible for squeezing the oral cleaning agent 20 in the container 200 out in a direction pointing to the brush head end 110. By accurately controlling the extrusion mechanism 300, it can be ensured that the amount squeezed out each time is appropriate to avoid waste.

[0050] Optionally, the extrusion mechanism 300 can be equipped with an electronic control system, such as a sensor and a motor drive, to achieve more precise extrusion volume control. A speed adjustment function is added so that the user can adjust the extrusion speed according to personal preference and oral cleaning needs.

[0051] The detachable design allows the container 200 and the extrusion mechanism 300 to be easily detached and connected to the toothbrush body 100, so that the container can be detached separately and connected to the compensating agent for replenishment, and any oral cleaning agent and maintenance ingredients for oral care, cleaning, treatment, etc. can be added as needed. The applicability of the product is improved. The container 200 and the extrusion mechanism 300 of different brands and models can be used interchangeably.

[0052] Optionally, a variety of containers 200 with different capacities and materials can be provided to meet the needs of different users.

[0053] The present application sets a mounting cavity 130 on the toothbrush body 100, and the container 200 is detachably set in the mounting cavity 130, wherein the container 200 has a housing cavity 210 for containing the oral cleaner 20, and a first opening 220 and a second opening 230 connected to the housing cavity 210, the first opening 220 is connected to the extrusion port 111 through the mounting cavity 130, and the second opening 230 is used for adding the oral cleaner 20, so that the housing 200 can repeatedly add the oral cleaner 20 as needed, without being limited to the specified oral cleaner 20, and the oral cleaner 20 can be any oral cleaner and maintenance component for oral care, cleaning, treatment, etc., thereby improving the applicability of the electric toothbrush 10.

[0054] Reference Figures 2 to 4 According to an embodiment of the present invention, a spring telescopic structure 400 is provided on the second opening 230 , and the spring telescopic structure 400 is used to limit the oral cleaning agent 20 to enter the accommodating cavity 210 in one direction.

[0055] It is understandable that the spring telescopic structure 400 can be pulled up or compressed when subjected to external force, such as when the oral cleaner 20 is added, so that the oral cleaner 20 can smoothly enter the accommodating chamber 210. When there is no external force, the spring telescopic structure 400 can return to its original state, preventing the cleaner from flowing out of the second opening 230, thereby ensuring the storage safety of the cleaner. In this way, through the elasticity and restoring force of the spring telescopic structure 400, the cleaner in the accommodating chamber 210 can be effectively prevented from leaking due to vibration or shaking during use. When adding the cleaner, the user does not need to worry about the problem of overdose or leakage, but simply pours the cleaner through the second opening 230, which is easy to operate and improves the user experience.

[0056] Furthermore, the spring telescopic structure 400 includes a spring 410 and a movable cover plate 420 . The movable cover plate 420 is connected to one end of the spring 410 . The movable cover plate 420 has a first position for opening the second opening 230 and a second position for closing the second opening 230 .

[0057] In one embodiment, the second opening 230 is disposed at the bottom of the container 200 , and the second opening 230 is a one-way spring liquid inlet, through which the cavity cleaning agent 20 or additives can be continuously added.

[0058] It is understandable that the spring 410 is the main power source of the telescopic structure. The spring 410 can be stretched and deformed when subjected to external force, and return to its original state after the external force disappears. The spring 410 can drive the movable cover 420 to switch between opening and closing the second opening 230. The movable cover 420 is connected to one end of the spring 410, and the other end can be connected to the inner wall of the accommodating chamber 210. The position of the movable cover 420 is affected by the expansion and contraction of the spring 410. The movable cover 420 has two main positions, that is, when subjected to external force (such as the user adding oral cleaner 20), the spring 410 is pulled up under the extrusion of the supplement 30, so that the movable cover 420 moves into the accommodating chamber 210, thereby opening the second opening 230 and allowing the supplement 30 to enter. When the external force disappears, the spring 410 returns to its original state, and the movable cover 420 returns to its original position, closing the second opening 230 to prevent the oral cleaner 20 from leaking.

[0059] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, an extrusion channel 140 connecting the extrusion port 111 and the mounting cavity 130 is formed in the toothbrush body 100, and the mounting cavity 130 is provided with a docking port 131 connected to the extrusion channel 140, and the docking port 131 is used for docking with the first opening 220.

[0060] It is understandable that an extrusion channel 140 is designed inside the toothbrush body 100, and the extrusion channel 140 connects the extrusion port 111 and the installation cavity 130. A docking port 131 is provided at the connection between the installation cavity 130 and the extrusion channel 140, and the docking port 131 is provided for docking with the first opening 220 of the receiving member 200. When the receiving member 200 is installed in the installation cavity 130, its first opening 220 can be directly connected with the extrusion channel 140, thereby ensuring that the oral cleaning agent 20 can smoothly pass through the first opening 220 and the extrusion channel 140 from the receiving cavity 210, and finally reach the extrusion port 111 and be applied to the bristles.

[0061] Specifically, the extrusion channel 140 serves as the main flow path for the oral cleaner 20 from the container 200 to the extrusion port 111. The design of the extrusion channel 140 needs to ensure smooth flow to avoid obstruction of the cleaner during the flow. The installation cavity 130 provides an installation space for the container 200, and the docking port 131 is a bridge between the installation cavity 130 and the extrusion channel 140, ensuring that the first opening 220 of the container 200 can be accurately and stably docked with the extrusion channel 140. The docking setting of the first opening 220 and the docking port 131 needs to be precise and stable to ensure that the oral cleaner 20 will not leak from the docking point during the extrusion process. The operational convenience and stability of the product are improved.

[0062] Reference Figure 1 or Figure 2 According to one embodiment of the present utility model, a one-way valve 500 or a duckbill valve 600 is provided on the extrusion channel 140 .

[0063] It is understandable that, according to this embodiment, a one-way valve 500 or a duckbill valve 600 is provided on the extrusion channel 140 of the electric toothbrush 10 to ensure that the oral cleaning agent 20 can flow from the container 200 to the extrusion port 111 of the brush head end 110 in a one-way manner, prevent liquid from overflowing, increase the controllability of the electric toothbrush 10, and thus ensure hygiene and safety during use.

[0064] The one-way valve 500 only allows the detergent to flow in one direction, that is, from the container 200 to the brush head. When the squeezing action occurs, the one-way valve 500 opens to allow the detergent to pass through; when there is no squeezing or backflow, the one-way valve 500 closes to prevent the detergent from flowing back.

[0065] The duckbill valve 600 is a flexible rubber check valve, and its working principle is similar to that of the one-way valve 500, but it has better sealing and buffering effects. The opening and closing of the duckbill valve 600 depends on the pressure change of the detergent. When squeezed, the duckbill part opens to allow the detergent to pass through; when there is no pressure or backflow, the duckbill part is tightly closed to prevent backflow. The two can be set as needed. Of course, other forms of valve bodies can also be set in other embodiments to prevent liquid overflow or backflow, etc.

[0066] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the extrusion port 111 is disposed on a side of the brush head end 110 having bristles.

[0067] It is understandable that the extrusion port 111 of the electric toothbrush 10 is disposed on the side of the brush head end 110 with bristles, so that the oral cleaning agent 20 can be directly applied to the bristles, thereby improving the utilization rate of the cleaning agent and allowing the user to more conveniently use the cleaning agent on the bristles to clean the oral cavity when brushing teeth.

[0068] Specifically, the extrusion port 111 is located at one side of the brush head end 110, closely adjacent to the bristles. When the user needs to apply the oral cleaner 20, they only need to gently squeeze the container 200, and the oral cleaner 20 will flow directly onto the bristles through the extrusion channel 140 and the extrusion port 111. In this way, when the user brushes his teeth, the oral cleaner 20 on the bristles can directly contact the teeth and oral cavity surface, achieving a better cleaning effect.

[0069] Reference Figure 1 and Figure 2 According to one embodiment of the utility model, the extrusion mechanism 300 includes a stepper motor 310, a screw rod 320 and a push plate 330, one end of the push plate 330 is connected to the container 200, and the other end is connected to the stepper motor 310 to squeeze the oral cleaner 20 in the accommodating cavity 210 toward the extrusion port 111.

[0070] It is understandable that the extrusion mechanism 300 of the electric toothbrush 10 includes a stepper motor 310, a screw rod 320 and a push plate 330. The precise and controllable extrusion of the oral cleaning agent 20 is achieved, the delivery accuracy of the oral cleaning agent 20 is improved, and the dosage of the oral cleaning agent 20 in a specific area or different areas can be effectively controlled, which can be more efficient and improve practicality.

[0071] Specifically, the stepper motor 310 is used as a power source, and the stepper motor 310 can rotate accurately according to a preset step or pulse signal. By controlling the rotation angle and speed of the stepper motor 310, the precise control of the moving distance and speed of the push plate 330 can be achieved. The screw rod 320 is connected to the output shaft of the stepper motor 310, and when the stepper motor 310 rotates, the screw rod 320 will rotate accordingly. The design of the screw rod 320 can convert the rotational motion of the stepper motor 310 into the linear motion of the push plate 330, so as to realize the reciprocating movement of the push plate 330. One end of the push plate 330 is connected to the receiving member 200, and the other end is connected to the stepper motor 310 through the screw rod 320. When the stepper motor 310 drives the screw rod 320 to rotate, the push plate 330 will reciprocate in the direction pointing to the brush head end 110. This movement will apply pressure to the oral cleaner 20 in the receiving chamber 210, so that it moves toward the extrusion port 111, thereby realizing the extrusion of the cleaner.

[0072] Reference Figures 1 to 3 According to one embodiment of the utility model, one end of the push plate 330 is located in the accommodating cavity 210 to separate the accommodating cavity 210 into a first cavity 211 and a second cavity 212. The oral cleaner 20 is located in the first cavity 211. The stepper motor 310 drives the push plate 330 to squeeze the oral cleaner 20 from the second cavity 212 toward the first cavity 211.

[0073] It is understood that one end of the push plate 330 in the extrusion mechanism 300 is located in the accommodating cavity 210, dividing the accommodating cavity 210 into a first cavity 211 and a second cavity 212. The accommodating member 200 is provided with a sealed through-hole along the direction from the gripping end 120 toward the brush head end 110 of the toothbrush body 100, and one end of the push plate 330 passes through the sealed through-hole and is connected to the stepper motor 310. The oral cleaning agent 20 is stored in the first cavity 211. When the stepper motor 310 is working, it will drive the push plate 330 to move from the second cavity 212 to the first cavity 211, thereby squeezing the oral cleaning agent 20 in the first cavity 211. Since the push plate 330 is directly driven by the stepper motor 310, precise control of the extrusion of the oral cleaning agent 20 can be achieved. By adjusting the rotation angle and speed of the stepper motor 310, the moving distance and speed of the push plate 330 can be controlled, thereby achieving precise adjustment of the extrusion amount of the cleaning agent. The push plate 330 forms a physical barrier, effectively preventing the oral cleaning agent 20 from leaking out of the accommodating chamber 210. In particular, when the electric toothbrush 10 is not in operation or during transportation, the push plate 330 can ensure the safe storage of the cleaning agent. Compared with the traditional design of squeezing the cleaning agent through a piston or a push rod, the design using the push plate 330 simplifies the structure of the extrusion mechanism 300, reduces the manufacturing cost and the difficulty of maintenance.

[0074] Optionally, the oral cleaning agent 20 includes at least one of toothpaste, auxiliary additives and oral care agents.

[0075] It is understandable that the oral cleaning agent 20 includes at least one of toothpaste, auxiliary additives and oral care agents, and provides users with a more comprehensive and effective oral cleaning experience through a variety of combinations.

[0076] Among them, toothpaste is the main component of the oral cleaner 20. Toothpaste contains abrasives, detergents, fluoride, etc., which can remove stains and bacteria on the surface of teeth, while protecting tooth enamel and preventing tooth decay.

[0077] Auxiliary additives can further enhance the cleaning effect of toothpaste or provide other functions. For example, peppermint oil or other natural extracts can be added to provide fresh breath; or ingredients with antibacterial and anti-inflammatory effects can be added to relieve oral inflammation or oral ulcers.

[0078] Oral care products usually include ingredients with specific functions, such as hemostatic agents for gum bleeding, desensitizing agents for tooth sensitivity, or nutrients that can enhance gum health, etc. They can provide effective solutions for specific oral problems.

[0079] In some embodiments, the electric toothbrush 10 also includes a circuit board, a squeeze button and a battery assembly. The squeeze button is communicatively connected to the circuit board, and the squeeze button portion is exposed on the outer side of the toothbrush body 100. The circuit board and the battery assembly are installed in the toothbrush body 100. The circuit board and the extrusion mechanism 300 are electrically connected to the battery assembly, and the circuit board and the extrusion mechanism 300 are communicatively connected.

[0080] It is understandable that the electric toothbrush 10 of this embodiment, in addition to the above-mentioned brush head, bristles, extrusion port 111 and extrusion mechanism 300, also adds key components such as circuit boards, extrusion buttons and battery packs. Working together, the electric toothbrush 10 has the characteristics of intelligence and automation. The user only needs to press a button to extrude the oral cleaner 20. And it is not limited to being able to extrude toothpaste only before starting. In addition, during the process, the cleaner can be replenished in real time through human or machine recognition areas, or the cleaner can be increased or compensated for specific areas. At the same time, due to the use of a circuit board for precise control, the electric toothbrush 10 can achieve precise adjustment of the extrusion amount of the oral cleaner 20 to meet the needs of different users. In addition, the use of battery packs has also significantly improved the battery life and service life of the electric toothbrush 10.

[0081] Among them, the circuit board is the control center of the electric toothbrush 10, which is responsible for receiving and processing signals from the squeeze button and controlling the action of the extrusion mechanism 300 according to the signal. At the same time, the circuit board is also responsible for electrically connecting with the battery assembly to ensure the power supply of the electric toothbrush 10. The squeeze button is an interface for the user to interact with the electric toothbrush 10. It is partially exposed on the outer side of the toothbrush body 100, which is convenient for the user to operate. When the user presses the squeeze button, it sends a signal to the circuit board, triggering the circuit board to control the extrusion mechanism 300. The battery assembly is the power supply part of the electric toothbrush 10, which is installed in the toothbrush body 100 to provide the required power for the circuit board and the extrusion mechanism 300. The battery assembly usually adopts a rechargeable design to ensure the long-term use of the electric toothbrush 10.

[0082] In some embodiments, the toothbrush body 100 further includes a display panel, which is mounted on the outer surface of the toothbrush body 100 , and is used to display the remaining amount of the oral cleaner 20 .

[0083] It is understandable that a display panel is added to the toothbrush body 100 of the electric toothbrush 10. The display panel is mounted on the outer surface of the toothbrush body 100, usually in a position that is easy for the user to view, such as the side or top of the toothbrush handle. The introduction of the display panel provides the user with intuitive information about the remaining amount of the oral cleaning agent 20.

[0084] Through the display panel, the user can clearly see the remaining amount of the current oral cleaner 20 (such as toothpaste). When the remaining amount of the oral cleaner 20 is lower than a preset threshold, the display panel may remind the user in a specific way to replace or replenish the cleaner in time. This helps to ensure that the user always has enough cleaner to complete each brushing task. Through intuitive display and timely reminders, the display panel makes the use of the electric toothbrush 10 more convenient and efficient. The user does not need to open the container 200 or judge the remaining amount of the cleaner by feel, but only needs to check the display panel to obtain accurate information.

[0085] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
