Description

Technical Field

[0001] This utility model relates to the technical field of electric toothbrush accessories, specifically to a water-blocking sleeve for an electric toothbrush with a supporting function. Background Technology

[0002] An electric toothbrush, invented by Philippe-Guy Woog, uses a motor to rapidly rotate or vibrate, causing the brush head to vibrate at high frequency. This instantly breaks down toothpaste into fine foam, deeply cleaning between teeth. At the same time, the vibration of the bristles promotes blood circulation in the mouth and massages the gum tissue.

[0003] However, when using an electric toothbrush, toothpaste water flows down the handle, mainly due to the following reasons:

[0004] High-frequency vibration inertia: The high-frequency vibration of the electric toothbrush motor causes the toothpaste to be affected by centrifugal force, making it easy to splash from the connection between the brush head and the handle.

[0005] Structural design flaw: If the joint between the brush head and the handle is not sealed properly, the paste mixed with saliva will seep into the gap and drip down the handle.

[0006] Excessive toothpaste: Users are used to squeezing the brush bristles full, and the toothpaste expands excessively and overflows when vibrating.

[0007] Angle issue: When brushing your teeth, the brush head should be facing downwards, as gravity accelerates the flow of liquid.

[0008] It will cause the following harms:

[0009] Hygiene risks: Residual paste can breed bacteria, contaminating handles or countertops, especially when shared by multiple people, posing a high risk of cross-infection.

[0010] Poor user experience: the dripping toothpaste liquid easily stains the cuffs.

[0011] Equipment wear and tear: Liquid seepage into the interior may corrode circuitry and shorten product lifespan. Utility Model Content

[0012] To address the shortcomings of existing technologies, this utility model provides a water-blocking sleeve for electric toothbrushes with a supporting function. It is easy to install, has a good fastening effect, and can effectively prevent the flowing liquid from contacting the toothbrush handle and prevent liquid from staining the cuffs, thus effectively solving the problems existing in the prior art.

[0013] The objective of this utility model is achieved through the following technical solution:

[0014] An electric toothbrush water-blocking sleeve with a supporting function includes a sleeve body. The side wall of the sleeve body is a guide member, and a clamping mechanism is provided inside. The top of the sleeve body has an opening through which the electric toothbrush drive shaft protrudes. The drive shaft passes through the opening, allowing the sleeve body to fit over the top of the electric toothbrush, separating the toothbrush head from the toothbrush handle. This prevents liquid from flowing down the brush head from contacting the handle during brushing, effectively preventing liquid from entering the handle through the button and contacting the circuit board, causing short circuits and corrosion, thus extending the lifespan of the electric toothbrush. The clamping mechanism is deformable, facilitating compatibility with different brands and models of electric toothbrushes, exhibiting excellent compatibility. Furthermore, the clamping mechanism has a self-recovering capability; after deformation, it tightly grips the side wall of the toothbrush handle, preventing... The sleeve detaches from the toothbrush handle. The guide expands from top to bottom, completely enveloping the toothbrush handle, preventing liquid from dripping onto the handle even if it flows down the outer edge of the sleeve. The guide directs the liquid flow, preventing it from contacting the handle through gravity. A support is also provided on the guide, allowing the electric toothbrush to stand at a certain angle on a horizontal surface, keeping the brush head away from the horizontal for drop protection. If the toothbrush tipps over when upright, the sleeve's elasticity cushions the impact, minimizing the force when the handle contacts the horizontal surface. When placed horizontally, the support keeps the handle at an angle to the horizontal, preventing it from rolling.

[0015] In one embodiment, the upper end of the sleeve body is a fixing plate, which is placed between the toothbrush head and the toothbrush handle. When the toothbrush head is fastened to the toothbrush handle, the fixing plate is also fastened. The opening is located in the middle of the fixing plate to facilitate the exposure of the drive shaft. The guide is connected to the side of the fixing plate. After installation, the bottom of the toothbrush head is connected to the guide to facilitate the drainage of liquid flowing down during brushing. The clamping mechanism is located on the inner wall of the guide. While fastening the fixing plate, the clamping mechanism also clamps the toothbrush handle to complete the double fastening. The clamping mechanism consists of a plurality of clamps.

[0016] In one embodiment, the clips are arranged in a circular array around the center of the opening on the inner wall of the guide, ensuring that the clamping mechanism applies force evenly to bite against the side wall of the toothbrush handle. There is a gap between the head end of the clip and the head end of the opposite clip to facilitate insertion into the toothbrush handle. The gaps between the heads of all the clips form a multi-arc-shaped hollow, which is easy to place in the toothbrush handle and provides excellent biting effect after insertion.

[0017] In one embodiment, the card has a base, the bottom surface of which is connected to the inner wall of the guide member. The front end of the base has a contact surface that is in contact with the side wall of the toothbrush handle. The contact surface can deform and has a strong frictional force on the side of the contact surface that contacts the toothbrush handle. The contact surface and the base are smoothly connected, making the card as a whole arc-shaped and the entire locking mechanism petal-shaped.

[0018] In one embodiment, the support member is provided with a support ridge, which is disposed on the outer wall of the guide member. The support ridge is triangular in shape, and the bottom corners of two adjacent support ridges can form a three-point support state with the bottom edge of the electric toothbrush handle, so that the brush head of the electric toothbrush can be lifted up and the toothbrush handle can be placed horizontally on a horizontal surface.

[0019] In one embodiment, the fixing plate is light-transmitting, and a bead is provided at the lower end of the support ridge. The user can directly observe the light emitted by the toothbrush handle through the fixing plate, allowing the user to instantly identify the signal emitted by the toothbrush handle. Water flows through the support ridge and then gathers at the bead to drip down.

[0020] In one embodiment, a relief groove is provided between the fitting surface and the base, which makes the fitting surface more easily deformable, making it easier for the sleeve body to be installed on the toothbrush handle.

[0021] In one embodiment, the material of the sleeve body is elastic soft rubber, which can be silicone or rubber. Silicone has the following characteristics: it has high temperature resistance and can be used in a wide temperature range (-60℃ to 250℃), does not deform at high temperatures, and maintains elasticity at low temperatures; it has chemical stability, is resistant to acids and alkalis, and is antioxidant and anti-aging, making it suitable for harsh environments; it is biocompatible, non-toxic, and odorless, and is widely used in the medical and food fields; it has flexibility, good elasticity, and tear resistance, and can be made into complex shapes, making it a good material for making sleeve bodies; it is waterproof and moisture-proof, has low air permeability, and excellent sealing performance; it is environmentally friendly, recyclable, and meets green material standards. Rubber has good elasticity and can undergo large deformations.

[0022] In one embodiment, the sleeve body is made of plastic. Plastic is lightweight, durable, and inexpensive, making it suitable for mass production. It has excellent waterproof and corrosion-resistant properties, making it suitable for use in various environments. It has good insulation properties and is widely used in the electronics and electrical fields. It is highly malleable and easy to process into various shapes and colors to meet diverse needs. Its transparent or translucent properties are suitable for packaging and display. It is hygienic and safe, and is widely used in the food and medical industries. It has low density, making it convenient to transport and carry. It has high chemical stability and does not easily react with other substances. It is recyclable, reducing resource waste.

[0047] Example

[0048] Please see Figure 1-7A water-blocking sleeve for an electric toothbrush with a supporting function includes a sleeve body 1. The sidewall of the sleeve body 1 is a guide member 2, and a clamping mechanism 3 is provided inside. The top of the sleeve body 1 has an opening 4 through which the electric toothbrush drive shaft protrudes. The drive shaft passes through the opening 4, allowing the sleeve body 1 to fit over the top of the electric toothbrush, separating the toothbrush head from the toothbrush handle. The clamping mechanism 3 is deformable and has a self-recovering capability, tightly engaging the sidewall of the toothbrush handle. During installation, first separate the toothbrush head from the toothbrush handle, align the opening 4 with the drive shaft, and then... After inserting the sleeve body 1, the drive shaft passes through the sleeve body 1. During insertion, if the side wall area of ​​the toothbrush handle is larger than the area of ​​the gap in the clamping mechanism 3, the toothbrush handle will compress the clamping mechanism 3, causing it to deform. Simultaneously, the clamping mechanism 3, due to its self-restoring ability, experiences a self-restoring force at the deformed area, generating a biting force on the side wall of the toothbrush handle. After the toothbrush head is installed on the toothbrush handle, the upper end of the sleeve body 1 is clamped between the toothbrush head and the toothbrush handle, making them inseparable. At the same time, the clamping mechanism 3 also clamps the side wall of the toothbrush handle, forming a double fixation to ensure the sleeve body... The fixed effect of the guide member 2 is that it expands from top to bottom and completely covers the toothbrush handle. The guide member 2 can guide the flow direction of the liquid, so that the liquid cannot contact the toothbrush handle. The guide member 2 is also provided with a support member 5. The support member 5 can make the electric toothbrush tilted at a certain angle on the horizontal surface, so that the brush head of the electric toothbrush is away from the horizontal surface. When brushing, the liquid in the mouth will flow down the toothbrush head due to the change of hand gestures and the gap between the lips. When the liquid flows to the sleeve body 1, the liquid will be guided by the guide member 2 and flow from the guide member 2. The liquid drips onto the outer wall of component 2, preventing it from contacting the toothbrush handle. When the electric toothbrush needs to be placed horizontally with the toothbrush head tilted away from the horizontal plane, simply place the toothbrush handle horizontally so that the sleeve body 1 contacts the horizontal plane. This creates a triangular support structure between the bottom of the support component 5 and the lower side wall of the toothbrush handle, keeping the toothbrush head tilted. When the electric toothbrush is placed upright, if it tilts, the support component 5 will collide with the horizontal plane instead of the toothbrush handle. Through its ability to deform to a certain extent, it will offset the impact force and prevent damage to the toothbrush handle.

[0049] Preferably, the upper end of the sleeve body 1 is a fixing plate 6, the opening 4 is provided in the middle of the fixing plate 6, the flow guide 2 is connected to the side of the fixing plate 6, the clamping mechanism 3 is provided on the inner wall of the flow guide 2, and the clamping mechanism 3 is composed of a plurality of clamping parts 7.

[0050] By adopting the above technical solution, the thickness of the fixing plate 6 is no more than one millimeter, ensuring that the toothbrush handle and toothbrush head can still be stably connected to the drive shaft after the fixing plate 6 is clamped, thus ensuring the vibration effect. The clamping mechanism 3 is composed of a plurality of clamping parts 7 to ensure the engagement effect.

[0051] Preferably, the card 7 is arranged in a circular array on the inner wall of the guide 2 with the center of the opening 4 as the axis. There is a gap between the head end of the card 7 and the head end of the card 7 opposite it. The gap between the heads of all the card 7 forms a multi-arc-shaped hollow.

[0052] By adopting the above technical solution, the clip 7 takes the center of the opening 4 as the axis, ensuring that all clips 7 deform together and generate self-recovering force when squeezed by the toothbrush handle, so as to achieve the effect of uniformly biting the side wall of the toothbrush handle, while effectively supporting the guide 2, making it round and full and not deformed. The head spacing of all clips 7 is the same, leaving enough space to facilitate the insertion of the toothbrush handle.

[0053] Preferably, the card 7 is provided with a base 8, the bottom surface of which is connected to the inner wall of the guide 2, and the front end of the base 8 is provided with a contact surface 9, which smoothly transitions with the base 8, making the card 7 as a whole arc-shaped.

[0054] By adopting the above technical solution, the contact surface 9 can generate friction when the toothbrush handle enters, requiring the user to exert force to insert the sleeve body 1. After insertion, the friction becomes a resistance to prevent the sleeve body 1 from falling off, effectively preventing the sleeve body 1 from falling off the toothbrush handle during use.

[0055] Preferably, the support member 5 is provided with a support ridge 10, which is disposed on the outer wall of the guide member 2. The support ridge 10 is triangular in shape, and the bottom corners of two adjacent support ridges 10 and the bottom edge of the electric toothbrush handle can form a three-point support state to lift the brush head of the electric toothbrush.

[0056] By adopting the above technical solution, when the electric toothbrush is placed horizontally, the two adjacent support edges 10 are in contact with the horizontal surface, forming a three-point support posture with the bottom edge of the toothbrush handle, so that the electric toothbrush is supported tilted on the horizontal surface. When the electric toothbrush falls, the support edges 10 are in contact with the horizontal surface, transmitting the impact force to the guide 2. At this time, the guide 2 can deform to absorb the impact force and prevent damage to the toothbrush handle.

[0057] Preferably, the fixing piece 6 is light-transmitting, and the lower end of the supporting ridge 10 is also provided with a bead 11.

[0058] By adopting the above technical solution, when the toothbrush handle is equipped with a light ring, the user can promptly identify the signal released by the electric toothbrush through the fixing piece 6, and the water flow will slide from the guide piece 2 to the support ridge 10 and converge and drip at the bead 11.

[0059] Preferably, a clearance groove 12 is also provided between the mating surface 9 and the base 8.

[0060] By adopting the above technical solution, the space provided by the positioning groove 12 is to avoid deformation of the fitting surface 9, which facilitates deformation of the fitting surface 9 and reduces the force required for the user to insert the sleeve body 1.

[0061] Preferably, the material of the body 1 can be silicone or rubber.

[0062] By adopting the above technical solution, in this application, the material of the body 1 is silicone, and silicone has the following characteristics:

[0063] Temperature resistance: Wide applicable temperature range (-60℃ to 250℃), no deformation at high temperatures, and maintains elasticity at low temperatures;

[0064] Chemical stability: Resistant to acids and alkalis, antioxidant, and anti-aging, suitable for harsh environments;

[0065] Biocompatibility: Non-toxic and odorless, widely used in the medical and food fields;

[0066] Flexibility: It has good elasticity and tear resistance, and can be made into complex shapes, making it a good material for making the body of the suit;

[0067] Waterproof and moisture-proof with low air permeability; excellent sealing performance; environmentally friendly, recyclable, and meets green material standards.

[0068] Preferably, the material of the body 1 can be plastic.

[0069] By adopting the above technical solutions, plastics are lightweight, durable, and inexpensive, making them suitable for large-scale production; they possess excellent water and corrosion resistance, making them suitable for use in various environments; they have good insulation properties, making them widely used in the electronics and electrical fields; they are highly malleable, easily processed into various shapes and colors to meet diverse needs; their transparent or translucent properties are suitable for packaging and display; they are hygienic and safe, widely used in the food and medical industries; they have low density, making them convenient to transport and carry; they have high chemical stability, not easily reacting with other substances; and they are recyclable, reducing resource waste.

[0070] Working principle: The sleeve body 1 is placed at the connection between the toothbrush head and the toothbrush handle, so that the two clamp the sleeve body 1. At the same time, the clamping mechanism 3 inside the sleeve body 1 bites the toothbrush handle, further fixing the sleeve body 1. When in use, the guide 2 can cover the toothbrush handle and guide the liquid that slides down during brushing to the support ridge 10, and then drop it through the ball 11 to prevent the liquid from contacting the toothbrush handle. When the electric toothbrush tipps over, the sleeve body 1, which is made of silicone, can provide cushioning for the electric toothbrush and prevent damage to the electric toothbrush. When it is necessary to tilt the toothbrush to prevent it from tilting, the toothbrush is placed horizontally on a horizontal surface, and the sleeve body 1 can support the toothbrush and keep the toothbrush head away from the horizontal surface.

[0071] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
