Abstract
Description
Technical Field
[0001] This utility model belongs to the field of oral hygiene technology, specifically a teeth cleaning device. Background Technology
[0002] In oral hygiene, hidden areas such as interdental spaces and gingival sulci vary from person to person due to individual differences in the width and shape of these spaces (wide gaps, narrow depressions, long-path gaps, etc.), requiring targeted cleaning. However, existing tools generally suffer from standardized specifications and insufficient adaptability: toothbrushes can only clean the outer surface of teeth and cannot reach into the interdental spaces; dental floss or floss picks have a single linear structure, making it difficult to match gaps of different widths, and they are prone to deviation when operating deep in the mouth; interdental brushes have fixed sizes and cannot adapt to individual tooth differences, and the rigid brush head can easily scratch the gums; water flossers are not powerful enough to remove stubborn plaque and cannot accurately adapt to narrow areas of different shapes. Because these tools lack targeted design for individual tooth differences, they either do not clean thoroughly or easily damage oral tissues, failing to meet the precise cleaning needs of different people. Utility Model Content
[0003] To address the problems existing in the background art, this utility model provides a teeth cleaning device.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a dental cleaning device, comprising a U-shaped bracket and a cleaning mechanism; one end of the U-shaped bracket is a cavity connection end, and the other end is a fixed end; the cleaning mechanism includes a handle, an inlet wire, a cleaning unit, and an anti-detachment component; the upper end of the handle is conical, and the lower end is cylindrical; the upper end of the handle is fixedly connected to one end of the inlet wire, and the other end of the inlet wire is fixedly connected to the anti-detachment component; the cleaning unit is fixed to the middle section of the inlet wire; the cylindrical structure of the handle is press-fitted with the cavity connection end; the outer wall of the fixed end is provided with a limiting groove adapted to the anti-detachment component; the limiting groove is press-fitted with the anti-detachment component; and a slot communicating with the limiting groove is provided on the fixed end.
[0005] The cleaning unit is a rhomboid cleaning body; The rhomboid cleaning body is made by connecting the base sides of at least three isosceles triangular strips together by hot pressing. The base side of the isosceles triangular strip is the long side, and the two sides are the short sides. The guide line passes through the intersection of the rhomboid cleaning body and is fixedly connected.
[0006] The cleaning unit is a cylindrical micro-brush; The cylindrical microbrush body has a hollow structure, and the inner diameter of the hollow structure is adapted to the diameter of the guide wire. The cylindrical microbrush body is strung on the guide wire through the hollow structure, and after being strung, it is fixed to the guide wire by hot pressing or bonding process. The outer surface of the cylindrical microbrush body is provided with dense microfibers.
[0007] The cleaning unit is a circular cleaning membrane assembly; The circular cleaning membrane assembly consists of multiple circular cleaning membranes. Each circular cleaning membrane has a through hole in its center that matches the diameter of the guide wire. The multiple circular cleaning membranes are connected in series to the guide wire through the through hole and are fixedly connected to the guide wire.
[0008] The fixed end of the U-shaped bracket is higher than the cavity connection end.
[0009] The anti-detachment component is spherical, disc-shaped, or has a polygonal cross-section.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Comprehensive cleaning coverage without blind spots, adaptable to various scenarios: Three differentiated cleaning units are used to precisely match different cleaning scenarios - the diamond-shaped cleaning body is suitable for wide gaps between teeth, the cylindrical micro-brush body is suitable for narrow and concave areas (such as the gingival sulcus), and the round cleaning membrane set is suitable for long path gaps (such as around the tooth root). It can specifically remove plaque and food debris that are difficult to reach by traditional cleaning tools, and thoroughly solve the problem of cleaning dead spots such as gaps between teeth and deep in the oral cavity.
[0011] 2. Flexible usage modes and stable and safe cleaning process: The cleaning unit can be used alone by hand (suitable for regular easily accessible areas) or with a U-shaped bracket (suitable for areas deep in the oral cavity such as far from the tooth root); the bracket fixes the guide line through the interference fit between the fixed end and the anti-dislodgement component, ensuring that the guide line is straight and horizontal, avoiding the cleaning unit from shifting or tilting, which not only improves the cleaning accuracy, but also prevents damage to the gums and teeth due to improper operation, and is especially suitable for the stable support needs when cleaning deep in the oral cavity.
[0012] 3. Excellent hygiene and cost-effectiveness: The cleaning mechanism is a disposable component, which can effectively avoid cross-infection and ensure oral hygiene safety; the U-shaped support is a reusable component, which does not require frequent replacement of the support structure. While reducing the cost of use, the food-grade ABS and high-temperature resistant PP materials used are compatible with common disinfection methods, ensuring the safety of repeated use.
[0013] 4. Gentle on gums, suitable for sensitive gums: The flexible strip of the diamond-shaped cleaning body, the ultra-fine bristles of the cylindrical micro-brush body (diameter ≤0.05 mm, length 0.1-1 mm), and the thin and flexible structure of the round cleaning film can flexibly conform to the irregular curved surface of the teeth. Through gentle contact, it reduces mechanical stimulation to sensitive gums, balancing cleaning power and gum care, making it suitable for people with sensitive gums.
[0014] 5. Convenient operation and high cleaning efficiency: The interference fit between the handle and the bracket cavity ensures precise transmission of control force. Simple operations such as swinging and rotating can drive the cleaning unit to generate sufficient friction. The spacing design of the circular cleaning membrane group forms a guide channel, which can promptly remove the peeled stains, avoid secondary pollution, and further improve cleaning efficiency.
[0015] In summary, this utility model, through its multiple advantages of "precise adaptation + flexible mode + hygienic efficiency + gentle gum protection", not only solves the problem of blind spots in the cleaning of traditional dental cleaning tools, but also takes into account the safety, convenience and cost-effectiveness of use. It can meet the needs of different oral conditions and different cleaning scenarios, and is especially suitable for people who have high requirements for deep oral cleaning.

Detailed Implementation
[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0018] This embodiment describes a dental cleaning device, including a U-shaped bracket 1 and a cleaning mechanism. One end of the U-shaped bracket 1 is a cavity connection end 11, and the other end is a fixed end. The cleaning mechanism includes a handle 2, an inlet wire 3, a cleaning unit, and an anti-detachment component 4. The upper end of the handle 2 is conical, and the lower end is cylindrical. The upper end of the handle 2 is fixedly connected to one end of the inlet wire 3, and the other end of the inlet wire 3 is fixedly connected to the anti-detachment component 4. The cleaning unit is fixed to the middle section of the inlet wire 3. The cylindrical structure of the handle 2 is press-fitted with the cavity connection end 11. The outer wall of the fixed end is provided with a limiting groove 121 adapted to the anti-detachment component 4. The limiting groove 121 is press-fitted with the anti-detachment component 4. The fixed end is provided with a slot 12 communicating with the limiting groove 121.
[0019] The cleaning unit is a rhomboid cleaning body 5; The rhomboid cleaning body 5 is made by connecting the base sides of at least three isosceles triangular strips 51 together by hot pressing. The base side of the isosceles triangular strip 51 is the long side, and the two sides are the short sides. The guide line 3 passes through the intersection of the rhomboid cleaning body 5 and is fixedly connected.
[0020] The cleaning unit is a cylindrical micro brush body 6; The cylindrical microbrush body 6 has a hollow structure, and the inner diameter of the hollow structure is adapted to the diameter of the guide line 3. The cylindrical microbrush body 6 is strung on the guide line 3 through the hollow structure, and after being strung, it is fixed to the guide line 3 by hot pressing or bonding process. The outer surface of the cylindrical microbrush body 6 is provided with dense microfibers.
[0021] The cleaning unit is a circular cleaning membrane assembly; The circular cleaning membrane assembly consists of multiple circular cleaning membranes 7. Each circular cleaning membrane 7 has a through hole in its center that matches the diameter of the guide line 3. The multiple circular cleaning membranes 7 are connected in series to the guide line 3 through the through holes and are fixedly connected to the guide line 3.
[0022] The fixed end of the U-shaped bracket 1 is higher than the cavity connection end 11.
[0023] The anti-detachment component 4 is spherical, disc-shaped, or has a polygonal cross-section.
[0024] This dental cleaning device utilizes a synergistic mechanism of "U-shaped bracket 1 positioning + precise action of the cleaning mechanism" to achieve deep cleaning of areas that are difficult to reach with traditional cleaning tools, such as interdental spaces and gingival sulci, by employing three different cleaning units (diamond-shaped cleaning body 5 for wide-gap cleaning, cylindrical micro-brush body 6 for narrow concave areas, and circular cleaning membrane group 7 for long-path gaps). The core of the device is to use the operating handle 2 to drive the cleaning units on the guide line 3 to form targeted friction, sweeping or multi-dimensional contact in the dental cleaning area. The cleaning mechanism can be used alone, or it can be used in conjunction with the U-shaped bracket 1 for areas that are difficult to reach deep in the oral cavity, such as far from the tooth root. The limiting and fixing function of the bracket ensures that the cleaning process is more stable, safe and efficient. For the cleaning unit using the rhomboid cleaning body 5, it is supported by an introductory line 3 (materials can be medical-grade nylon thread, stainless steel microfilament, polymer fiber, etc.) with a length of 10-50 mm and a diameter of 0.01-0.1 mm. The middle section of the introductory line 3 is connected to three or more isosceles triangular strips 51 (materials can be medical-grade PET film, food-grade silicone film, etc.) with a base length of 5-30 mm. Their thickness can be 0.005-0.3 mm. Through hot pressing or bonding processes, the isosceles triangular strips 51 are evenly distributed relative to the outer periphery of the introductory line 3. The bases of all the isosceles triangular strips 51 are pressed together to form an evenly distributed rhomboid assembly structure. One end of the introductory line 3 is fixedly connected to the conical structure at the upper end of the handle 2, and the other end of the introductory line 3 is fixedly connected to an anti-detachment component 4 (the anti-detachment component 4 can be spherical, disc-shaped, or have a polygonal cross-section). (And used in conjunction with the limiting slot 121) When used alone, the user directly holds the handle 2 to operate the guide wire 3, inserts the guide wire 3 into the interdental space and then gently swings it out to achieve cleaning; When used with the bracket for areas far from the tooth root, the cylindrical structure at the lower end of the handle 2 is pressurized with the cavity connection end 11 of the U-shaped bracket 1, and the guide wire 3 is inserted into the slot 12 of the fixed end, and the anti-dislodgement component 4 is inserted into the limiting slot 121 to form a pressurized fit, which physically locks the guide wire 3 to prevent it from sliding. With the help of the U-shaped bracket 1, it is positioned to reach deep into the oral cavity. The horizontal straight state of the guide wire 3 can ensure that the cleaning unit moves parallel to the interdental space, avoiding cleaning blind spots caused by the tilt of the guide wire 3. The thin and flexible isosceles triangular strip membrane 51 can flexibly conform to the irregular curved surface around the tooth root, and form sufficient friction with dental plaque and food debris through the side and end face to achieve precise and comprehensive interdental cleaning; When the cleaning unit is a cylindrical micro-brush body 6, the guide wire 3 has a diameter of 0.01-0.1 mm and a length of 10-40 mm. The middle section is equipped with a hollow cylindrical micro-brush body 6 (material can be soft PP, silicone, etc.) with a diameter of 0.5-3 mm and a cylindrical length of 1-5 mm. The cylindrical micro-brush body 6 is individually processed into a hollow shape and strung on the guide wire 3, and then fixed by heat pressing or bonding. One end of the guide wire 3 is fixed to the handle 2, and the other end is connected to the anti-detachment component 4. When used alone, the cylindrical micro-brush body 6 can be sent into the regular cleaning area by holding the handle 2. The guide wire 3 is inserted into the interdental space. It can be slightly swung for interdental spaces and rotated for gingival sulcus. The rotating drive uses microfibers (materials such as nylon and polyester can be selected) to remove stains; when used with the bracket, the handle 2 and the cavity connection end 11 of the U-shaped bracket 1 are press-fitted, and the guide wire 3 is inserted into the slot 12 of the fixed end, and the anti-dislodgement component 4 is locked into the limiting slot 121 to achieve limiting. The U-shaped bracket 1 provides stable support for the cleaning mechanism, making it easy to accurately deliver the cylindrical micro-brush body 6 into the narrow area far from the tooth root. The outer surface of the cylindrical micro-brush body 6 is provided with dense microfibers with a diameter ≤0.05 mm (length can be selected 0.1-1 mm), which can reach deep into tiny depressions for cleaning. At the same time, the soft contact of the ultra-fine fibers can reduce mechanical stimulation to sensitive gums. When using the circular cleaning membrane assembly, the guide wire 3 has a diameter of 0.01-0.1 mm and a length of 10-40 mm. Multiple circular cleaning membranes 7 (materials such as medical-grade polyurethane membranes and fiber membranes) with a diameter of 0.5-3 mm, a thickness of 0.01-0.5 mm, and a spacing of 0.5-2 mm are connected in series in the middle section. The circular cleaning membranes 7 are connected to the guide wire 3 through a central through-hole. One end of the guide wire 3 is fixed to the handle 2, and the other end is connected to the anti-dislodgement component 4. The guide wire 3 is inserted into the interdental space, and then the handle 2 drives the circular cleaning membrane 7 assembly to move or rotate in easily accessible areas, achieving multi-point friction cleaning. When used with the bracket, the handle 2 and the cavity connection end 11 of the U-shaped bracket 1 are press-fitted, simultaneously guiding the guide wire... The inlet wire 3 is inserted into the slot 12 of the fixed end, and the anti-dislodgement component 4 is snapped into the limiting slot 121 of the fixed end of the U-shaped bracket 1 to achieve fixation. With the help of the U-shaped bracket 1, the circular cleaning membrane 7 is kept in a straight line arrangement, making it easier to penetrate into the far part of the tooth root. The thin and flexible circular cleaning membrane 7 makes full contact with the tooth through its edge and surface during movement. While rubbing away dental plaque, the spacing of 0.5-2 mm between two adjacent circular cleaning membranes 7 forms a flow channel, which allows water or saliva to fully enter the cleaning area and promptly remove the peeled dental plaque and food residue, avoiding the residue from causing secondary pollution. The series structure of multiple circular cleaning membranes 7 can cover a longer cleaning path and adapt to gaps of different lengths around the tooth root. During the use of the three cleaning units, the interference fit between the cavity connection end 11 and the handle 2 ensures precise transmission of control force, and the interference fit between the limiting slot 121 and the anti-dislodgement component 4 restricts the axial displacement of the guide line 3 to prevent slippage. At the same time, the cleaning mechanism is a disposable component to avoid cross-infection, and the U-shaped bracket 1 is reusable (the material can be food-grade ABS, high-temperature resistant PP, etc.). While reducing the cost of use, it ensures the stability of the support structure when cleaning the distal area of the tooth root. This utility model can smoothly enter all the gaps between teeth to remove residue, making up for the inability of toothbrushes to clean the gaps between teeth, and transforming the passive cleaning that was only done when food got stuck into teeth into daily active oral maintenance.
