Description

Technical Field

[0001] The present invention relates to the technical field of electric toothbrushes, in particular to a 360-degree rotating intelligent paste-free electric toothbrush. Background Art

[0002] An electric toothbrush is a modern oral hygiene tool that uses an electric motor to rotate or vibrate the brush head, providing a more efficient and thorough clean. The rapid rotation or vibration of the motor creates a high-frequency vibration in the brush head, instantly breaking down toothpaste into fine foam, deeply cleaning between teeth while also promoting blood circulation and massaging gum tissue. Electric toothbrush heads primarily feature three types of motion: reciprocating linear motion, rotary motion, and sets that combine both. The bristles of the toothbrush head are made of soft plastic fibers with spherical tips, ensuring they are gentle on teeth and gums while minimizing brushing effectiveness.

[0003] There is an existing electric toothbrush such as the announcement number CN222032691U, which is named an electric toothbrush, including a manual toothbrush and a brush handle combined with each other, the brush handle including a main shell and at least a part of a control component, a drive component, a mounting part, a connecting part, and an inner bracket arranged in the main shell, the inner bracket is connected to the mounting part, the control component and the drive component are arranged in at least one of the inner bracket and the mounting part, and the control component is electrically connected to the drive component; the manual toothbrush extends into the mounting part, the connecting part is used to move in the length direction relative to the mounting part under the action of external force, and apply force to the mounting part; the mounting part is used to apply force to the manual toothbrush and fix the manual toothbrush in the mounting part; the electric toothbrush can be adapted to the manual toothbrush, which is conducive to improving its versatility.

[0004] The friction generated by the bristles of existing traditional electric toothbrushes and traditional ordinary manual toothbrushes is limited, which cannot achieve the friction required to clean tobacco stains, tea stains, coffee stains and other tooth stains. In addition, traditional electric toothbrushes only swing back and forth at a certain angle like a pendulum clock with the axis of the disc toothbrush head as the center line, and do not rotate 360 degrees. For this reason, we provide a 360-degree rotating smart paste-free electric toothbrush. Summary of the Invention

[0005] The object of the present invention is to provide a 360-degree rotating intelligent paste-free electric toothbrush to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a 360-degree rotating intelligent paste-free electric toothbrush, comprising an electric toothbrush, wherein the electric toothbrush comprises a toothbrush shell, a positioning wall, a silicone cleaning brush head, a passive shaft, and an active shaft. The active shaft is arranged inside the toothbrush shell, the passive shaft is arranged at the upper end of the active shaft, the silicone cleaning brush head is arranged at the front end of the passive shaft, and the positioning wall is arranged on the outside of the silicone cleaning brush head.

[0007] Preferably, a first notch is provided at the front end of the toothbrush housing, a driving shaft card is provided in the first notch, and the driving shaft card is engaged and connected with the first notch.

[0008] Preferably, a second notch is provided at the upper end of the toothbrush housing, a passive shaft card is provided in the second notch, and the passive shaft card is engaged and connected with the second notch.

[0009] Preferably, a rotating rod is provided at the lower end of the driving shaft, and the driving shaft and the rotating rod are assembled and connected.

[0010] Preferably, an assembly groove is provided at the lower end of the toothbrush housing, and the electric toothbrush is assembled and connected to the base through the assembly groove provided at the lower end.

[0011] Preferably, a silicone soft cover is provided on the outer side of the positioning wall, and the silicone soft cover is bonded to the positioning wall.

[0012] Preferably, a first clamping plate is provided in the toothbrush housing, a second clamping plate is provided at the upper end of the first clamping plate, and the toothbrush housing positions and connects the rotating rod through the first clamping plate and the second clamping plate.

[0013] Preferably, a snap-in groove is provided at the lower end of the silicone cleaning brush head, and a snap-in block is provided at the upper end of the passive shaft. The silicone cleaning brush head is assembled and connected through the snap-in groove provided at the lower end and the snap-in block provided at the upper end of the passive shaft.

[0014] Preferably, a plurality of groups of blades are provided on the inner side of the upper end of the silicone cleaning brush head, and the plurality of groups of blades are evenly arranged inside the silicone cleaning brush head.

[0015] Preferably, a fitting is provided at the upper end of the driving shaft, the upper end of the fitting is provided at the lower end of the passive shaft, and the driving shaft is rotatably connected to the passive shaft via the fitting.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention adds pumice, aluminum oxide, silicone oil, and anti-friction agent, which are selected cleaning materials, to a silicone toothbrush head. After mixing in a certain proportion, the toothbrush head is vulcanized and formed into a round shape. The friction generated during rotation is utilized. By adding silicone oil and anti-friction agent, the heat dissipation effect can be improved by adding water during cleaning. In an accelerated cooling environment during cleaning, the teeth are cleaned at a certain rotation speed, thereby achieving an excellent cleaning effect without damaging the teeth. This solves the problem of limited friction generated by the bristles of traditional electric toothbrushes and traditional ordinary manual toothbrushes, and realizes cleaning of the tooth surface without toothpaste. At the same time, it can also clean the tartar that cannot be cleaned by ordinary toothbrushes, and cannot clean tobacco stains, tea stains, coffee stains, etc.

[0017] (2) By changing the structure of the toothbrush head, the disc toothbrush head can be rotated at a fixed point, and then the toothbrush head can be pulled and swung by hand to clean the entire oral cavity. By adding a circle of positioning walls below the toothbrush head surface around the rotating surface of the toothbrush head, after the toothbrush head enters the mouth, the cheek muscles on the outside of the mouth and the teeth will slightly squeeze the toothbrush head, or slightly press the toothbrush handle, so that the positioning walls will be close to the surface of the teeth and gums. The friction generated when the toothbrush head rotates will be offset by the friction generated by the positioning walls and the teeth or gums, thereby achieving the problem of positioning the toothbrush head, thereby solving the problem of traditional electric toothbrushes, which only swing back and forth at a certain angle like a pendulum clock with the axis of the disc toothbrush head as the axis, and do not rotate 360 degrees.

[0018] (3) The present invention minimizes the resistance torque by changing the fulcrum of friction resistance, thereby achieving the result of minimizing the torque of holding the toothbrush handle. The support point is increased during the rotation of the toothbrush head. A circle of positioning walls (the top is made of soft rubber, which makes it comfortable when combined with the tooth surface and also prevents the risk of the outer shell of the toothbrush head from hitting the teeth and gums during use) is added to the rotating surface of the toothbrush head. After the toothbrush head enters the mouth, the cheek muscles outside the mouth and the teeth will slightly squeeze the toothbrush head, or slightly press the toothbrush handle. In this way, the positioning walls will be close to the surface of the teeth and gums. The friction generated when the toothbrush head rotates will be offset by the friction generated when the positioning walls are close to the surface of the teeth or gums, thereby solving the problem of the toothbrush head hitting the mouth due to irregular movement when the toothbrush head rotates 360 degrees.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-5 The present invention provides an embodiment of a 360-degree rotating intelligent paste-free electric toothbrush, comprising an electric toothbrush 1, wherein the electric toothbrush 1 comprises a toothbrush shell 11, a positioning wall 12, a silicone cleaning brush head 15, a passive shaft 16, and an active shaft 17. The active shaft 17 is arranged in the toothbrush shell 11, the upper end of the active shaft 17 is provided with a passive shaft 16, the front end of the passive shaft 16 is provided with a silicone cleaning brush head 15, and the outer side of the silicone cleaning brush head 15 is provided with a positioning wall 12. By adding selected cleaning materials such as pumice, aluminum oxide, silicone oil, and anti-wear agent into the silicone toothbrush head, mixing them in a certain proportion and then vulcanizing them into a round toothbrush head, the friction generated during rotation is utilized, and the heat dissipation effect can be improved by adding silicone oil and anti-wear agent in combination with the addition of water during cleaning. In the environment of accelerated cooling during cleaning, the teeth are cleaned at a certain speed, thereby achieving both excellent cleaning effect and the effect of not grinding the teeth, thereby solving the problem of the traditional electric toothbrush 1 and the traditional ordinary manual toothbrush. The friction force generated by the bristles of the toothbrush is limited and cannot meet the friction force required to clean tobacco stains, tea stains, coffee stains and other dental plaques. By changing the structure of the toothbrush head, the disc toothbrush head can be rotated at a fixed point, and then the toothbrush head can be pulled and swung by hand to clean the entire oral cavity. By adding a circle of positioning walls 12 lower than the toothbrush head surface around the rotating surface of the toothbrush head, after the toothbrush head enters the mouth, the cheek muscles outside the mouth and the teeth will slightly squeeze the toothbrush head, or slightly press the toothbrush handle. In this way, the positioning walls 12 will come close to the surface of the teeth and gums, and the friction force generated when the toothbrush head rotates will be offset by the friction force generated by the positioning walls 12 and the surface of the teeth or gums, thereby achieving the problem of positioning the toothbrush head, thereby solving the problem of the traditional electric toothbrush 1, which only swings back and forth at a certain angle like a pendulum with the axis of the disc toothbrush head as the axis, and does not rotate 360 degrees.

[0022] See also Figure 4 A first slot 5 is formed at the front end of the toothbrush housing 11 . A driving shaft card 14 is disposed in the first slot 5 , and the driving shaft card 14 is engaged with the first slot 5 .

[0025] See also Figure 2 The lower end of the toothbrush housing 11 is provided with an assembly groove 10, and the electric toothbrush 1 is assembled and connected with the base through the assembly groove 10 opened at the lower end, which facilitates the installation of the base.

[0026] See also Figure 4 A silicone soft cover 13 is provided on the outside of the positioning wall 12, and the silicone soft cover 13 is bonded and connected to the positioning wall 12 to play a protective role.

[0027] See also Figure 3 A first clipping plate 2 is provided in the toothbrush housing 11, and a second clipping plate 3 is provided on the upper end of the first clipping plate 2. The toothbrush housing 11 positions and connects the rotating rod 9 through the first clipping plate 2 and the second clipping plate 3, thereby playing the role of positioning and connecting the rotating rod 9.

[0028] See also Figure 3 The lower end of the silicone cleaning brush head 15 is provided with a snap-in groove 8, and the upper end of the passive shaft 16 is provided with a snap-in block 7. The silicone cleaning brush head 15 is assembled and connected through the snap-in groove 8 provided at the lower end and the snap-in block 7 provided at the upper end of the passive shaft 16, which facilitates the assembly of the silicone cleaning brush head 15 and the passive shaft 16.

[0029] See also Figure 5 , multiple groups of blades are arranged on the inner side of the upper end of the silicone cleaning brush head 15, and the multiple groups of blades are evenly arranged in the silicone cleaning brush head 15.

[0030] See also Figure 3 The upper end of the driving shaft 17 is provided with a matching piece 4, and the upper end of the matching piece 4 is provided at the lower end of the passive shaft 16. The driving shaft 17 is rotatably connected to the passive shaft 16 through the matching piece 4.

[0031] No ointment experiment: The no-paste test method is to use toothbrush heads of different conditions to move on the surface of a 1H PC sheet (the surface of a 1H PC sheet is not scratched and will not scratch the surface of the teeth) coated with paint, simulating the movement trajectory of the toothbrush when washing the mouth, and observe the final cleaning results; 1: Traditional electric toothbrush heads move across the surface and cannot clean the marks left by paint pens. There are two reasons for this: (1): The friction coefficient of the hairy material is low; (2): The frequency of an electric toothbrush, 26,000 Hz, cannot reach the cleaning frequency.

[0032] 2: The silicone cylindrical cleaning sheet with cleaning function is not effective when cleaned with an electric toothbrush. The reason is: The frequency of an electric toothbrush, 26,000 Hz, is not enough for cleaning.

[0033] 3: The silicone toothbrush head without cleaning function is driven by a polishing mechanism with a speed of 7000 rpm and has only a slight cleaning effect.

[0034] 4: The silicone toothbrush head with cleaning function is added with selected pumice 80 mesh, accounting for 5%, silicone oil 5%, anti-wear agent 2%, and aluminum oxide 5%. When it is dipped in water (cooling) and cleaned at a speed of 7000 rpm, it has excellent cleaning ability, but there are slight scratches on the PC surface.

[0035] Conclusion: Adding selected pumice stones can enhance cleaning power, but it will scratch the surface.

[0036] 5: The silicone toothbrush head with cleaning function is added with selected pumice 200 mesh, accounting for 5%, silicone oil 5%, anti-wear agent 2%, aluminum oxide 5%. When it is dipped in water (cooling) and cleaned at a speed of 7000 rpm, it has excellent cleaning ability and there are no scratches on the PC surface.

[0037] Conclusion: Adding selected pumice can enhance the cleaning ability. If the particle size is too coarse, it will scratch the surface. If the particle size is moderate, it will not damage the surface.

[0038] Summarizing the appeal, it concluded: 1: Ordinary electric toothbrushes and ordinary manual toothbrush structural products have poor cleaning capabilities.

[0039] 2: The silicone toothbrush head with cleaning material has poor cleaning ability at low speed.

[0040] 3: The silicone toothbrush head without cleaning material has poor cleaning ability at a speed of 7000 rpm.

[0041] 4: For a silicone toothbrush head with cleaning material, if the pumice stone is coarse in size, it will scratch the cleaning surface.

[0042] 5: The silicone toothbrush head with cleaning material has a cleaning effect and the fine particle size of the pumice stone will not scratch the cleaning surface.

[0043] Based on the above five experimental results, it can be concluded that the silicone toothbrush head with cleaning material has a strong cleaning effect, but the particle size of the pumice stone and the ratio of pumice stone, silicone, silicone oil and anti-wear agent must be adjusted to obtain both excellent cleaning effect and no damage to the cleaning surface.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
