Description

Technical Field

[0001] This utility model relates to the field of three-sided toothbrush technology, and in particular to an electric three-sided toothbrush. Background Technology

[0002] A large portion of the population uses a horizontal brushing method when brushing their teeth, brushing along the direction of the upper and lower teeth. Current toothbrushes only have one bristle surface, meaning users need to constantly adjust their brushing posture to ensure all three surfaces of the teeth are cleaned. This type of toothbrush and the resulting brushing method leads to low brushing efficiency. Therefore, a three-sided toothbrush is proposed, which can clean all three surfaces of the teeth simultaneously, effectively reducing brushing time by two-thirds, saving time and making it more convenient to use.

[0003] The existing Chinese utility model patent, CN219479466U, entitled "Three-Sided Toothbrush," only allows for manual, rapid back-and-forth movement of the three-sided toothbrush to achieve the effect of brushing teeth from all three sides. This method of brushing teeth lacks the convenience and effort-saving features of an electric toothbrush. Therefore, there is an urgent need for an electric three-sided toothbrush that can achieve the same brushing effect as an electric toothbrush. Utility Model Content

[0004] The purpose of this invention is to provide an electric three-sided toothbrush to solve the problem that existing three-sided toothbrushes can only be manually moved back and forth quickly to achieve the effect of brushing teeth on three sides, and do not have an electric function.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An electric three-sided toothbrush includes a handle, three brush heads, a micro motor, a battery, a gear assembly, flexible shafts, and brush rollers. The handle is connected to the three brush heads. The micro motor, the battery, and the gear assembly are all housed within the handle. The battery is electrically connected to the micro motor via a push-button switch. The power output end of the micro motor is connected to the power input end of the gear assembly. The brush rollers are rotatably mounted on three brushing surfaces of the three brush heads. Multiple flexible shafts are housed within the three brush heads. Each flexible shaft is connected to a power output end of the gear assembly and a power input end of one brush roller.

[0007] A further technical solution is that a cross-sectional groove is provided between the three brushing surfaces of the three-sided brush head.

[0008] A further technical solution is as follows: the gear assembly includes a gear disk, a driving gear, driven gears, and a central shaft. The gear disk is disposed inside the handle. The driving gear and the three driven gears are rotatably mounted on the gear disk. The driving gear meshes with the three driven gears. The power output end of the micro motor is connected to the power input end of the driving gear. The three central shafts are respectively mounted at the center of the three driven gears, and the three central shafts are respectively connected to the three flexible shafts.

[0009] A further technical solution is that the diameter of the driving wheel is smaller than the diameter of the driven wheel.

[0010] A further technical solution is that the brushing surfaces on both sides of the three-sided brush head are inclined outwards.

[0011] A further technical solution is that the three brushing surfaces of the three-sided brush head are provided with receiving grooves that are adapted to the brush roller.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This utility model proposes an electric three-sided toothbrush that overcomes the problem of traditional three-sided toothbrushes requiring manual and rapid back-and-forth movement to brush teeth. This three-sided toothbrush uses a micro motor, gear assembly, and flexible shaft to work together to drive the three brush rollers on the three-sided brush head to rotate together, so as to achieve the effect of automatically brushing three sides of the teeth, which is convenient and labor-saving.

[0014] Moreover, this electric three-sided toothbrush replaces the traditional horizontal brushing method, using a roller brushing method to reduce damage to the gums. Attached Figure Description

[0026] Example 1:

[0027] This implementation example Figure 1 and Figure 2 As shown, an electric three-sided toothbrush includes a handle 1, three brush heads 2, a micro motor 3, a battery 4, a gear assembly 5, flexible shafts 6, and brush rollers 7. The handle 1 is connected to the three brush heads 2. The micro motor 3, battery 4, and gear assembly 5 are all housed inside the handle 1. The battery 4 is electrically connected to the micro motor 3 via a push-button switch 8. The power output end of the micro motor 3 is connected to the power input end of the gear assembly 5. The brush rollers 7 are rotatably mounted on the three brushing surfaces of the three brush heads 2. Multiple flexible shafts 6 are housed inside the three brush heads 2. Each flexible shaft 6 is connected to one power output end of the gear assembly 5 and one power input end of a brush roller 7.

[0028] The working process of this three-sided toothbrush is as follows: First, put the battery 4 into the battery compartment of the handle 1 to power the micro motor 3. Then, squeeze the toothpaste onto the brush rollers 7 of the three-sided brush head 2. Next, press the button switch 8 to start the micro motor 3. The micro motor 3 drives the three flexible shafts 6 to start working through the gear assembly 5. The three flexible shafts 6 drive the three brush rollers 7 to rotate, thereby achieving the effect of automatic brushing of teeth.

[0029] Preferably, a cross-sectional groove 9 is provided between the three brushing surfaces of the three-sided brush head 2.

[0030] The three-sided brush head 2 can be made of a flexible material and combined with the cross-sectional groove 9. When the size of the teeth changes, the three-sided brush head 2 can expand outward when it is squeezed by the teeth to adapt to the change in the teeth. This ensures that the two sides of the brushing surface of the three-sided brush head 2 are in close contact with the sides of the teeth, thereby improving the brushing effect.

[0031] Example 2:

[0032] Based on the above embodiments, this embodiment, for example Figure 3 and Figure 4As shown, the gear assembly 5 includes a gear disk 10, a driving gear 11, driven gears 12, and a central shaft 13. The gear disk 10 is located inside the handle 1. The driving gear 11 and the three driven gears 12 are rotatably mounted on the gear disk 10. The driving gear 11 meshes with the three driven gears 12. The power output end of the micro motor 3 is connected to the power input end of the driving gear 11. The three central shafts 13 are respectively mounted at the center of the three driven gears 12, and the three central shafts 13 are respectively connected to the three flexible shafts 6.

[0033] When the micro motor 3 starts, it drives the drive wheel 11 on the gear disk 10 to rotate. The drive wheel 11 drives the three driven wheels 12 to rotate together. The central shaft 13 on the driven wheel 12 is connected to the flexible shaft 6 through a connector. The flexible shaft 6 drives the brush rollers 7 on the three brushing surfaces of the three-sided brush head 2 to rotate.

[0034] It is worth noting that the structure of the gear assembly 5 can be further optimized by setting a reversing wheel between one of the driven wheels (driving the side brush roller 7 to rotate) and the driving wheel 11, so as to ensure that the driven wheels on both sides can drive the brush rollers 7 on both sides to rotate towards the inner bottom of the three-sided brush head 2 at the same time, so as to throw the tooth dirt to the inner bottom of the three-sided brush head 2 and ensure the cleaning effect.

[0035] Preferably, the diameter of the driving wheel 11 is smaller than the diameter of the driven wheel 12.

[0036] The driving wheel 11 and the driven wheel 12 can achieve a speed reduction effect.

[0037] Preferably, the brushing surfaces on both sides of the three-sided brush head 2 are inclined outwards.

[0038] This tilted design helps it fit the alveolar bone.

[0039] Preferably, the three brush heads 2 have receiving grooves 14 adapted to the brush rollers 7 on their three brushing surfaces.

[0040] The brush roller 7 is located in the receiving groove 14. The bristles of the brush roller 7 protrude outside the receiving groove 14. This is to prevent the brush roller 7 from protruding too much and affecting the teeth, and to ensure that the bristles can effectively clean the teeth.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
