[0026] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0027] In the description of the present application, it should be understood that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are intended to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate so that the embodiments of the present application can be implemented in a marking manner other than illustrated or described. In addition, "including", "having" and any variation thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of components, steps or units is not necessarily limited to those components, steps or units explicitly listed, and may also include other components, steps or units that are not explicitly listed but are inherent to these processes, methods, products or devices.

[0028] Teeth cleaning is crucial for oral health and even overall health. The mouth is the primary channel for food to enter the human body. Teeth, as important organs for chewing food, are exposed to various food residues and bacteria every day. If the teeth are not cleaned in time, food residues will remain and ferment in the mouth, breeding a large number of bacteria. These bacteria will produce acidic substances, which will gradually corrode the enamel on the surface of the teeth, causing caries, leading to tooth pain and sensitivity, and even affecting normal chewing function in severe cases. At the same time, bacteria can also cause gingivitis, with symptoms such as red, swollen gums and bleeding. Long-term development may lead to periodontitis, causing loose teeth and loss of teeth. In addition, bacteria in the mouth may also enter other parts of the body through the blood circulation, increasing the risk of systemic diseases such as cardiovascular disease and diabetes.

[0029] In order to maintain oral health, various dental cleaning tools have emerged. In the early days, people mainly used toothpicks to clean between teeth, but toothpicks are hard and can easily damage gums and teeth if used improperly. In addition, the cleaning effect is limited and it is impossible to completely remove food residues deep in the teeth.

[0030] Later, dental floss was introduced. It can, to a certain extent, go deeper into the gaps between teeth for cleaning. However, the integrated design of traditional dental floss means that once the floss part is worn, contaminated or damaged, the entire dental floss device needs to be replaced. This means a higher cost of use for consumers. For example, if a consumer buys a box of integrated dental floss, and the floss becomes fuzzy or breaks after a few uses, even if the handheld part is still intact, the entire floss has to be discarded and a new one purchased. This undoubtedly increases the cost of long-term use of dental floss for consumers.

[0031] In this regard, Figure 1 and Figure 2 As shown, a dental floss 10 of a preferred embodiment of the present application is provided with a plurality of dividing balls 1011. The dental floss 10 is divided by the plurality of dividing balls 1011 into a plurality of segments in which functional segments 1012 and buffer segments 1013 are alternately arranged. When the buffer segment 1013 is disconnected, a functional segment 1012 and the dividing balls at both ends of the functional segment 1012 form a dental cleaning unit 101.

[0032] By arranging a number of segmentation balls on the dental floss 10 and cutting the buffer section 1013, the following can be obtained: Figure 2 The dental cleaning unit 101 shown can be quickly assembled and disassembled when used with the dental cleaning device 1 with the first clamp ring 113 and the second clamp ring 123 of the present application. The dental floss 10 before cutting is easy to carry, and the dental cleaning unit 101 can be freely replaced without replacing the dental cleaning device 1, which reduces the cost of each use of the dental cleaning device 1, and can significantly reduce the cost of use with long-term use. Since the dental floss 10 and the dental cleaning device 1 can be produced separately, when the material of the dental floss 10 needs to be updated, there is no need to produce additional dental cleaning devices 1, which also reduces waste and reduces production costs.

[0033] like Figure 1 As shown, in the present application, the length of the buffer segment 1013 may be smaller than the length of the functional segment 1012 .

[0034] In another embodiment, the length of the functional segment 1012 may be 1.6 cm to 1.8 cm. The diameter of the segmentation ball may be less than 1 mm.

[0035] In the drawings of the application documents, in order to clearly show the assembly relationship between the various components of the toothbrush 1, the length of the dental floss 10, the diameter of the dividing ball and the diameter of the retaining ring have been adjusted. These dimensions in the drawings are different from the actual product dimensions, and the actual product dimensions are not determined by the drawings.

[0036] When drawing the drawings, if they are drawn completely according to the actual size, the key assembly structure may be difficult to see because the size of the components is too small or too large. For example, the dental floss 10 may be very thin in reality, and the diameter of the split ball is very small. If they are presented in the drawings according to the actual size, the assembly details of them with the main rod 11 and the clamping ring on the support rod may not be shown. Appropriately enlarging these sizes can make it more intuitive to understand how the components fit together.

[0037] It is understandable that when the tooth cleaner 1 is actually manufactured, it is necessary to follow the accurate design dimensions rather than the scaled dimensions of the attached drawings, so as to avoid problems such as product size errors and inability to use normally due to misunderstanding of the dimensions in the attached drawings.

[0038] Correspondingly, such as Figure 3 As shown, the present application further provides a tooth cleaner 1 , which comprises: a tooth cleaning unit 101 , a main rod 11 and an elastic auxiliary rod 12 .

[0039] The tooth cleaning unit 101 is composed of a functional segment 1012 and split balls at both ends of the functional segment 1012. The tail end 122 of the elastic auxiliary rod is connected to the main rod 11. The split ball at one end of the functional segment 1012 is detachably connected to the head end 111 of the main rod, and the split ball at the other end of the functional segment 1012 is detachably connected to the head end 121 of the elastic auxiliary rod. The elastic force of the elastic auxiliary rod 12 increases the angle between the elastic auxiliary rod 12 and the main rod 11, so that the functional segment 1012 is straightened.

[0040] The dental floss 10 with dividing balls can be divided into dental cleaning units 101 with dividing balls at both ends. The dental cleaning unit 101, as a basic unit, is detachably connected to the dental cleaning device 1, so that the dental floss 10 can be replaced separately without replacing the main rod 11, the elastic sub-rod 12 and other main body parts 117, thereby reducing material waste and reducing the cost of use.

[0041] Furthermore, in one embodiment, the main rod 11 includes a first snap ring 113, which is disposed at the head end 111 of the main rod, the first snap ring 113 is an open ring, the inner diameter of the first snap ring 113 is smaller than the diameter of the splitting ball, the functional section 1012 passes through the first snap ring 113 through the opening, and the splitting ball contacts the first snap ring 113 to achieve a detachable connection between the splitting ball and the head end 111 of the main rod; the elastic auxiliary rod 12 includes a second snap ring 123, the second snap ring 123 is disposed at the head end 121 of the elastic auxiliary rod, the second snap ring 123 is an open ring, the inner diameter of the second snap ring 123 is smaller than the diameter of the splitting ball, the functional section 1012 passes through the second snap ring 123 through the opening, and another splitting ball contacts the second snap ring 123 to achieve a detachable connection between the splitting ball and the head end 121 of the elastic auxiliary rod.

[0042] The split ball of the dental cleaning unit 101 cooperates with the clamps on the main rod 11 and the elastic auxiliary rod 12 to achieve a stable fixation of the dental floss 10. The inner diameters of the first clamp 113 and the second clamp 123 are smaller than the diameter of the split ball, and the functional section 1012 passes through the two clamps, and the split ball contacts the clamps respectively. This design prevents the dental floss 10 from falling off or shifting easily during use.

[0043] The elastic force of the elastic auxiliary rod 12 increases the angle between the elastic auxiliary rod 12 and the main rod 11, thereby straightening the functional segment 1012. The straightened functional segment 1012 can better fit the gap between teeth during cleaning, and deeply clean the food residues and dirt in the gap between teeth.

[0044] The structural design is simple and reasonable, and is easy for users to operate. When installing the tooth cleaning unit 101, it is only necessary to pass the functional segment 1012 through the first clamp ring 113 and the second clamp ring 123, and fix it by the interference between the split ball and the clamp ring, without complicated installation steps. Moreover, when it is necessary to replace the tooth cleaning unit 101, the operation is relatively simple, which reduces the user's threshold for use and improves the convenience of use.

[0045] In one embodiment of the present application, Figure 4 The main rod 11 shown can also include a nozzle 114, a channel 115 and a liquid supply port 116. The nozzle 114 is arranged at the head end 111 of the main rod, the channel 115 is arranged inside the main rod 11, and the liquid supply port 116 is arranged at the tail end 112 of the main rod. The nozzle 114 faces the head end 121 of the elastic sub-rod, and the channel 115 is respectively connected to the nozzle 114 and the liquid supply port 116. The liquid supply port 116 is used to introduce tooth cleaning liquid or tooth cleaning gas.

[0046] The arrangement of the nozzle 114, the channel 115 and the liquid supply port 116 enables the tooth cleaner 1 to have the function of auxiliary cleaning with tooth cleaning liquid or tooth cleaning air. When the tooth cleaning liquid is introduced into the liquid supply port 116, the tooth cleaning liquid is ejected from the nozzle 114 through the channel 115, and the food residues and dental plaque in the gaps between teeth can be more effectively removed in combination with the cleaning effect of the dental floss 10. For example, for some stubborn dirt adhering to the teeth, the flushing of the tooth cleaning liquid can soften and preliminarily clean it, and the physical friction of the dental floss 10 can achieve a better cleaning effect. If the dental cleaning air is introduced, the high-speed airflow can impact the gaps between teeth, further enhancing the cleaning effect, especially for removing tiny granular dirt.

[0047] The nozzle 114 faces the head end of the elastic auxiliary rod 12, so that the sprayed dental cleaning liquid or dental cleaning air can directly act on the working area of ​​the dental floss 10, covering the tiny gaps and corners that are difficult to reach by the dental floss 10. This helps to achieve more comprehensive cleaning, reduce cleaning blind spots, ensure that all parts of the oral cavity can be effectively cleaned and cared for, and further maintain oral health.

[0048] The design that allows both tooth cleaning liquid and tooth cleaning air to be introduced meets the diverse cleaning needs of different users. For example, for users with sensitive gums, they can choose to use tooth cleaning liquid for gentle cleaning; while for users who need stronger cleaning power, they can choose to use tooth cleaning air. In addition, in different usage scenarios, users can also switch flexibly, such as using tooth cleaning liquid for daily cleaning, and using tooth cleaning air when they feel a strong bad breath or need to clean quickly.

[0049] Accordingly, reference Figure 5 , an exemplary assembly procedure is given. Since the elastic auxiliary rod 12 is elastic and can undergo a certain elastic deformation, one of the segmentation balls is first inserted into the second snap ring 123 on the elastic auxiliary rod 12. At this time, the tooth cleaning unit 101 is lifted to deform the elastic auxiliary rod 12 so that the other segmentation ball can be inserted into the first snap ring 113, thereby completing the assembly.

[0050] If you want to disassemble it, you can use Figure 5 In the reverse step, the split ball at the first snap ring 113 is first pulled up to separate the split ball from the first snap ring 113 , and then the other split ball can be separated from the second snap ring 123 to achieve disassembly.

[0051] Further, in one embodiment of the present application, if Figure 6 The tooth cleaner 1 shown also includes a main body 117, and the tail end 112 of the main rod is fixed to the main body 117; the main body 117 includes a vibration motor 1171, a battery 1172 and a switch 1173. When the switch 1173 is turned on, the battery 1172 supplies power to the vibration motor 1171, and the vibration motor 1171 drives the main rod 11 to vibrate.

[0052] The vibrating motor 1171 enables the main rod 11 to vibrate when the tooth cleaner 1 is in use. This vibration, combined with the cleaning action of the dental floss 10 and the flushing of the dental cleaning liquid or dental cleaning air, can more efficiently remove dirt between teeth.

[0053] Vibration can make the dental floss 10 fit the tooth surface and tooth gaps better, enhance the scraping and loosening effect of food residues and dental plaque, and make the cleaning process faster and more thorough. For example, for stubborn stains attached to the adjacent surfaces of teeth, the vibration-assisted dental floss 10 can remove them more easily, greatly saving cleaning time compared to purely manual dental cleaning tools.

[0054] The installation method of the vibration motor is determined according to the type of motor. For example, in one embodiment, a mechanical torsion oscillation motor can be used as the vibration motor, including an eccentric rotor, and the transmission shaft is an eccentric structure. When the motor is running, the rotation of the eccentric rotor will generate unbalanced centrifugal force, thereby causing the motor as a whole to vibrate, thereby driving the entire device to vibrate. Generally, a spring sheet or a mechanical baffle is used to limit the movement of the eccentric rotor to ensure that it vibrates within a certain range and transmits the vibration to the main body.

[0055] In another embodiment, a brushless reciprocating oscillation motor can also be used. The electromagnetic coil is directly wound on the stator. When an alternating current is passed, an alternating magnetic field is generated. Generally, a permanent magnet with a magnetic suspension structure is used as the rotor. Under the action of the alternating magnetic field generated by the stator, the rotor will reciprocate according to the law of the magnetic field change, omitting the brush structure and reducing mechanical friction. It can be equipped with a control circuit and a sensor to accurately control the vibration frequency, amplitude and other parameters of the motor.

[0056] In one embodiment of the present application, the main body 117 further includes a containing bottle and a water pump. The containing bottle is used to contain the tooth cleaning liquid, and the water pump is used to pump the tooth cleaning liquid from the containing bottle to the liquid supply port 116 .

[0057] The integrated container simplifies the teeth cleaning process by eliminating the need to carry an additional container for tooth cleaning liquid. The user only needs to start the tooth cleaning device 1, and the water pump can automatically extract the tooth cleaning liquid from the container for cleaning. Compared with the traditional method of requiring an external tooth cleaning liquid bottle or manually dipping the tooth cleaning liquid, the convenience of use is greatly improved. Whether it is for daily use at home or when traveling, it can be easier to complete teeth cleaning.

[0058] The storage bottle and the water pump are integrated into the main body 117, making the overall structure of the tooth cleaner 1 more compact. The number of external connection parts is reduced, reducing the risk of failure caused by loose parts, and improving the portability of the product. The product has a more regular appearance, is easy to store and carry, and is convenient for users to clean their oral cavity anytime and anywhere.

[0059] In one embodiment of the present application, the volume of the containing bottle may be 15 ml to 50 ml.

[0060] The water pump setting can achieve precise control of the amount of tooth cleaning liquid used. By adjusting the power or working time of the water pump, the appropriate amount of tooth cleaning liquid can be supplied according to different cleaning needs. For example, for light cleaning needs, the amount of tooth cleaning liquid pumped out can be reduced; for deep cleaning or when there is a lot of oral dirt, the amount can be increased, avoiding waste of tooth cleaning liquid while ensuring the cleaning effect.

[0061] In one embodiment of the present application, the main body 117 further includes a blade, which is installed at the bottom of the main body 117 and is used to cut the dental floss 10 .

[0062] The main body 117 is provided with a blade, so that the user can quickly cut the dental floss 10 to obtain the dental cleaning unit 101 when needed. There is no need to find additional cutting tools such as scissors, which saves time and is easy to operate.

[0063] The blade is mounted at the bottom of the main body 117, so that the dental flosser 1 becomes a more functional whole. The user does not need to worry about not being able to find a suitable tool when cutting the dental floss 10. This integrated design improves the usability and user experience of the product.

[0064] During disassembly, in addition to disassembly using steps that are reverse to those of assembly, the present application also allows the use of a blade to cut the used tooth cleaning unit 101 for quick disassembly, and the blade can be installed on the outer packaging.

[0065] Compared with the prior art, the dental floss 10 and the dental cleaning device 1 of the embodiment of the present application have the following beneficial effects:

[0066] The dental floss 10 and the dental cleaning device 1 of the embodiment of the present application are characterized in that the dental floss 10 with a dividing ball can be divided into dental cleaning units 101 with dividing balls at both ends. The dental cleaning unit 101 serves as a basic unit, and cooperates with the structure of the first clamping ring 113 and the second clamping ring 123 to realize the replacement of the dental floss 10 separately without replacing the main rod 11, the elastic auxiliary rod 12 and other main body parts 117, thereby reducing material waste and reducing the cost of use.

[0067] In any embodiment of the present application, the main rod 11 can be Figure 6 The bent rod shown can also be Figure 7 When using a straight rod such as Figure 6 When the rod is bent as shown, since the head end 111 of the main rod can be easily inserted into the oral cavity, the nozzle 114 can flush from the inside to the outside of the teeth. Figure 7 In the case of the straight rod shown, the nozzle 114 is located on the outside, so the teeth can be flushed from the outside to the inside. Figure 6 and Figure 7 The technical solutions are all within the protection scope of this application and are applicable to different usage scenarios. Those skilled in the art can adopt them as needed, and this application does not impose any restrictions on this.

[0068] The above is only a preferred implementation of the present application.
