Terms such as "upper," "lower," "left," "right," "front," "back," and "bottom" indicate directions or positions based on those shown in the accompanying drawings. These are for ease of description only and should not be construed as limitations on the present invention.
[0038] It should be noted that the oral irrigator includes a housing, a water storage unit, a water pump, a motor, and a nozzle. The motor and the water pump driven by the motor are placed within the housing cavity enclosed by the housing and are directly or indirectly supported by the housing. The water pump's outlet pipe is connected to the nozzle, which sprays water from the water storage unit in a pulsed stream from the pointed end of the nozzle, thereby cleaning the teeth, the spaces between teeth, the gums, or the tongue.
[0039] Since the toothbrush does not have a comprehensive waterproof function, during use, external water can easily enter the toothbrush through the gaps between the parts, corrode the internal parts of the toothbrush, and cause damage to the toothbrush.
[0040] like Figures 1-6 As shown, this embodiment provides a waterproof structure of a toothbrush, wherein an outer shell is arranged outside the main body of the toothbrush, and a sealing assembly is arranged at the connection between the main body of the toothbrush and the outer shell, and the sealing assembly is arranged to protrude outward to form at least two sealing protrusions, thereby increasing the sealing between the outer shell and the main body of the toothbrush, and the sealing assemblies on the upper cover plate and the lower cover plate can directly make the connection between the outer shell and the main body of the toothbrush stable, which can effectively prevent external water from entering the interior of the main body of the toothbrush, and protect the internal parts of the main body of the toothbrush from corrosion.
[0041] Specifically, it includes an outer shell and a main body of the tooth washer. The outer shell is formed in one piece. The outer shell is open at the top and bottom and has a hollow structure inside. The outer shell is sleeved outside the main body of the tooth washer, and both ends of the main body of the tooth washer pass through the outer shell.
[0042] The main body of the tooth washer includes an upper cover plate, a lower cover plate, a control assembly and a pumping assembly. The control assembly and the pumping assembly are arranged between the upper cover plate and the lower cover plate and connect the upper cover plate and the lower cover plate. The connection between the upper cover plate, the lower cover plate and the outer shell is provided with a sealing assembly. The setting of the sealing assembly not only seals the connection between the upper cover plate and the outer shell, and the connection between the lower cover plate and the outer shell, but also makes the sealing assembly on the upper cover plate and the sealing assembly on the lower cover plate stable after being squeezed.
[0043] The two sealing assemblies are respectively mounted on the upper and lower cover plates, and the sealing assemblies extend outward to form at least two sealing protrusions, which tightly fit the inner sidewall of the outer shell. The shape of the sealing protrusions can be designed according to the specific contour of the inner sidewall of the outer shell, such as using an arc, trapezoid, or wavy shape to maximize the contact area and enhance the sealing effect.
[0044] The sealing assembly is pre-installed on the upper and lower covers of the irrigator body to ensure quick positioning and a tight fit when the outer shell is installed. The inner diameter of the sealing assembly should be slightly smaller than the outer diameter of the corresponding part of the irrigator body to generate a certain preload force and improve the sealing effect. The preload force between the upper and lower covers of the irrigator body and the outer shell can interact with each other to achieve a stable connection between the irrigator body and the outer shell.
[0045] In one embodiment, the upper cover is provided with a first slot for placing the sealing assembly, and the lower cover is provided with a second slot for placing the sealing assembly. The purpose of the first slot is to prevent the sealing assembly from accidentally moving or falling off the upper cover during assembly. Through physical constraints, the sealing assembly can remain in place even under the action of external forces, thereby ensuring the accuracy and sealing of the installation. The purpose of the second slot is to prevent the sealing assembly from accidentally moving or falling off the lower cover during assembly. Through physical constraints, the sealing assembly can remain in place even under the action of external forces, thereby ensuring the accuracy and sealing of the installation.
[0046] The second slot works together with the first slot to form a double sealing and fixing mechanism, further enhancing the stability and sealing of the overall structure.
[0047] In one embodiment, the inner side wall of the outer shell extends inward to form a mounting block, the upper cover is located below the mounting block, and the upper cover is connected to the mounting block, increasing the connection points between the toothbrush body and the outer shell, making the connection between the toothbrush body and the outer shell more stable.
[0048] The mounting block not only positions the main body of the tooth washer for assembly, but also provides an additional connection point for the upper cover. When the upper cover is tightly connected to the mounting block, it not only increases the connection area between the main body of the tooth washer and the outer shell, but also significantly improves the stability of the connection.
[0049] Specifically, there are three mounting blocks. This arrangement helps to disperse the stress that may be generated during use of the dental cleaner and prevent loosening or damage caused by excessive force on a single point.
[0050] In one embodiment, the size of the upper cover is smaller than that of the upper cover, and the cross-section of the inner side wall from the bottom end of the outer shell to the location of the outer shell mounting block gradually decreases along the installation direction of the tooth rinser body. The purpose of this arrangement is to guide the tooth rinser body into the outer shell smoothly during installation, reducing assembly difficulty and errors.
[0051] In one embodiment, three sealing protrusions are provided, spaced evenly along the axis of the sealing assembly. This evenly spaced arrangement simplifies mold design and production, improving production efficiency. It also facilitates subsequent maintenance and replacement of the sealing assembly, enhancing the interchangeability and consistency of components.
[0052] In one embodiment, three sealing protrusions are provided, and the spacing between adjacent sealing protrusions gradually increases along the installation direction of the tooth rinser body. During assembly, the sealing protrusions closer to the installation direction of the tooth rinser body are more deformed by compression. The larger spacing ensures that adjacent sealing protrusions do not connect, thereby improving the sealing effect between the outer shell and the tooth rinser body.
[0053] In one embodiment, the control assembly includes a control circuit board, control buttons and a display screen. The control circuit board is arranged between the upper cover plate and the lower cover plate, and is installed on the inner shell between the upper cover plate and the lower cover plate by screws; the control buttons are fixedly arranged on the outer shell and electrically connected to the control circuit board; the display screen is electrically connected to the control circuit board.
[0054] In one embodiment, the pumping assembly includes an electric motor and a plunger pump. The electric motor is arranged between the upper cover plate and the lower cover plate and is installed in the inner housing between the upper cover plate and the lower cover plate. The electric motor is a brushless DC motor. When in use, the motor can always output strong and powerful power accurately and continuously. The running sound of the motor is only 50db, allowing users to experience the efficient texture brought by the quiet teeth cleaning. The built-in 1500MAH high-capacity polymer battery cell makes the motor's battery life reach 30 days. The vibration frequency of the motor is 2300 times per minute. Each teeth cleaning can deeply clean the teeth and gums. The selected AI intelligent high-precision chip ensures that each speed adjustment can run smoothly, effectively eliminating the frustration caused by speed change. The plunger pump is located between the upper cover plate and the lower cover plate and is connected to the motor. The motor is used to drive the plunger pump to rotate, thereby increasing the pressure of the water flowing into the plunger pump so that the water pressure meets the water pressure requirement for cleaning teeth.
[0055] In one embodiment, a charging assembly is also included, which includes a battery, a charging column and a silicone plug. The battery is arranged between the upper cover and the lower cover to provide power to the toothbrush; the charging column is arranged on the outer shell and is electrically connected to the battery; the silicone plug is sleeved on the connection between the charging column and the outer shell to provide waterproof protection for the connection between the shell and the charging column, thereby ensuring the charging assembly and improving the charging safety of the waterproof toothbrush.
[0056] In one embodiment, the outer side wall of the outer shell is provided with a number of anti-slip bumps, which can effectively increase the friction between the user's hand and the outer shell, so that good grip stability can be maintained even in a humid environment or when the user's hands are sweating, preventing accidental falling or dropping due to hand slippage.
[0057] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
[0058] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
