[0052] A smart electric toothbrush provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] Embodiment 1

[0054] Please also read Figure 1 as well as Figure 2, is a schematic diagram of the structure of an intelligent electric toothbrush provided by the present invention. The intelligent electric toothbrush includes a brush head part 1 and a driving part 2. The brush head part 1 includes a brush head frame and bristles. The brush head frame is provided with an occlusal groove 12 for teeth to occlude. The occlusal groove 12 includes a bottom surface and two oppositely arranged side surfaces. The bristles include first bristles 11a and second bristles 11b. The first bristles 11a are arranged on the two side surfaces, and the second bristles 11b are arranged on the bottom surface. The first bristles 11a and the second bristles 11b are respectively used to clean different surfaces of the teeth. The driving part 2 includes a driving mechanism and a driving shaft 22. One end of the driving shaft 22 is connected to the driving mechanism, and the other end of the driving shaft 22 is connected to the brush head frame. The driving mechanism is used to drive the driving shaft 22 to drive the brush head frame to move.

[0055] Furthermore, the number of the occlusal grooves 12 opened in the brush head skeleton may be one or two. Specifically, when there is one occlusal groove 12, the occlusal groove 12 can only accommodate one row of teeth (upper row of teeth or lower row of teeth). At this time, the inner surface and outer surface of the teeth are opposite to the two side surfaces of the occlusal groove 12, that is, the first bristles 11a are used to clean the inner surface and outer surface of the teeth; the occlusal surface of the teeth is opposite to the bottom surface of the occlusal groove 12, that is, the second bristles 11b are used to clean the occlusal surface of the teeth. With the above design, the smart electric toothbrush can cover multiple surfaces of the teeth for cleaning at the same time, which helps to improve the cleaning efficiency. When there are two occlusal grooves 12, the two occlusal grooves 12 can be used to accommodate the upper row of teeth and the lower row of teeth respectively, so as to achieve the cleaning of the upper row of teeth and the lower row of teeth at the same time, which is conducive to further improving the cleaning efficiency. This embodiment is mainly described by taking the case where there are two occlusal grooves 12 as an example.

[0056] In this embodiment, the brush head frame includes a first frame 10a and a second frame 10b fixed to the first frame 10a. The first frame 10a and the second frame 10b are both provided with an engaging groove 12. When the first frame 10a and the second frame 10b are both provided with an engaging groove 12, the opening direction of one of the engaging grooves 12 is opposite to the opening direction of the other engaging groove 12, so that the two rows of teeth can be respectively engaged in the two engaging grooves 12.

[0057] Furthermore, if Figure 2As shown, the brush head skeleton also includes a first plate-like structure 13, a second plate-like structure 14 and a third plate-like structure 15, wherein the second plate-like structure 14 is opposite to and spaced from the first plate-like structure 13, and the third plate-like structure 15 is connected between the first plate-like structure 13 and the second plate-like structure 14, so that the first plate-like structure 13 and the second plate-like structure 14 are simultaneously separated into a first part 101 and a second part 102, wherein the first part 101 and part of the third plate-like structure 15 form a first skeleton 10a, the second part 102 and another part of the third plate-like structure 15 form a second skeleton 10b, the gap between the first plate-like structure 13 of the first part 101 and the second plate-like structure 14 of the first part 101 forms one of the engaging grooves 12, and the gap between the first plate-like structure 13 of the second part 102 and the second plate-like structure 14 of the second part 102 forms another engaging groove 12.

[0058] Among them, the first plate-like structure 13, the second plate-like structure 14 and the third plate-like structure 15 are all flat plate structures. Since the first plate-like structure 13 and the second plate-like structure 14 are all flat plate structures, the brush head part 1 only covers part of the upper and lower rows of teeth, which is different from the U-shaped block electric toothbrush (i.e., the brush head is a U-shaped brush head) whose overall structure matches the shape of the two rows of teeth. Although the U-shaped block electric toothbrush can cover all teeth at once, at the same time, because the U-shaped block electric toothbrush is highly matched with the teeth, when the teeth are engaged on the U-shaped brush head, it is difficult for the U-shaped brush head to move relative to the teeth (for example, rotate or produce relative displacement). In addition, since the U-shaped block electric toothbrush usually cleans the teeth by vibrating the brush head through the vibration of the motor, the U-shaped block electric toothbrush is limited by its structural shape, so the vibration attenuation of its motor is more serious, resulting in poor cleaning effect. The brush head part 1 of the smart electric toothbrush provided in this embodiment has high mobility and can easily move relative to the teeth (such as rotating, displacing, etc.), which greatly improves the convenience of use and cleaning efficiency of the smart electric toothbrush.

[0059] Furthermore, the first plate-like structure 13 of the first part 101 and the second plate-like structure 14 of the first part 101 both have a first side surface 131 facing one of the bite grooves 12, that is, the two first side surfaces 131 are the two side surfaces of the bite groove 12 formed by the first part 101; the first plate-like structure 13 of the second part 102 and the second plate-like structure 14 of the second part 102 both have a second side surface 132 facing the other bite groove 12, that is, the two second side surfaces 132 are the two side surfaces of the bite groove 12 formed by the second part 102. The third plate-like structure 15 includes a first surface 151 located at the first part 101 and a second surface (not marked) located at the second part 102. The second surface is arranged opposite to the first surface 151, and the first surface 151 and the second surface respectively form the bottom surfaces of two bite grooves 12. That is, the two first side surfaces 131 and the first surface 151 are combined to form the bite groove 12 of the first part 101, and the two second side surfaces 132 and the second surface are combined to form the bite groove 12 of the second part 102.

[0060] Furthermore, on the third plate-like structure 15 , the first surface 151 may be provided with a plurality of penetration holes penetrating to the second surface, so as to help the toothpaste to penetrate from the first surface 151 to the second surface through the penetration holes.

[0061] Furthermore, in order to prevent the brush head frame from causing wear or damage to the oral cavity, the brush head portion 1 may also include a protective layer 16, such as Figure 3 As shown, the protective layer 16 completely covers the periphery and outer surface of the brush head frame to completely cover the corners of the brush head frame to prevent the brush head frame from hitting the teeth or gums when the brush head part 1 moves relative to the oral cavity, thereby preventing damage to the inside of the oral cavity. The protective layer 16 is made of a material with low hardness or a certain elasticity, such as a soft rubber material, so that the protective layer 16 can protect the inside of the oral cavity and improve the user's comfort.

[0062] Specifically, see Figure 2 as well as Figure 3 The protective layer 16 can be integrally formed into a protective cover that matches the shape of the brush head frame, and then the brush head frame is placed in the protective cover so that the protective layer 16 completely covers the outer surface and periphery of the brush head frame. The protective layer 16 can also be divided into several pieces and affixed to the outer surfaces and peripheries of the first plate-like structure 13 and the second plate-like structure 14, and the periphery of the third plate-like structure 15 respectively.

[0063] In this embodiment, the smart electric toothbrush can drive the drive shaft 22 to move through the drive mechanism, thereby driving the brush head frame to move. Figure 1 as well as Figure 4The drive shaft 22 and the brush head part 1 can be connected through a fixing rod 4. Specifically, one end of the fixing rod 4 is fixedly connected to the brush head part 1, for example, it can be fixedly connected to the outer surface of the first plate-like structure 13 or the outer surface of the second plate-like structure 14, and the other end of the fixing rod 4 is detachably connected to the other end of the drive shaft 22. The detachable connection method allows the drive mechanism to replace different brush head frames according to customer needs, which is conducive to improving the applicability of the drive mechanism.

[0064] Furthermore, the other end of the fixing rod 4 is provided with a first step groove 41, the groove side of the first step groove 41 includes a first horizontal step surface 411a and a first vertical step surface 411b fixedly connected to the first horizontal step surface 411a, and the other end of the driving shaft 22 forms a second step corresponding to the first step groove 41, the second step includes a second horizontal step surface 412a and a second vertical step surface 412b fixedly connected to the second horizontal step surface 412a. Specifically, when the fixing rod 4 is connected to the driving shaft 22, the second step is located in the first step groove 41, and the first horizontal step surface 411a and the second horizontal step surface 412a are correspondingly arranged and abutted against each other, and the first vertical step surface 411a and the second vertical step surface 412b are correspondingly arranged and abutted against each other, so as to realize the connection between the fixing rod 4 and the driving shaft 22. In this way, when the driving shaft 22 moves along its own length direction, due to the abutment between the second horizontal step surface 412a and the first horizontal step surface 411a, and the second vertical step surface 412b and the first vertical step surface 411a, the driving shaft 22 will never change in displacement relative to the fixed rod 4, thereby achieving the movement of the fixed rod 4 driven by the driving shaft 22.

[0065] Further, as an optional implementation, please refer to Figure 5 as well as Figure 6 The smart electric toothbrush can adopt a single drive solution, that is, when the number of the driving mechanisms of the driving part 2 is one, the structure of the driving part 2 can be specifically as follows: the driving part 2 also includes a driving shell 23 and a connecting component 24 fixedly connected to the driving shaft 22, the driving mechanism is located in the driving shell 23, and the connecting component 24 is located outside the driving shell 23, the output shaft 211 of the driving mechanism extends from the driving shell 23 to the outside of the driving shell 23 and is sleeved in the driving shaft 22, so that one end of the driving shaft 22 can telescope relative to the output shaft 211 of the driving mechanism, and the other end of the driving shaft 22 extends from the driving shell 23 to the outside of the driving shell 23 and is fixed to the brush head frame.

[0066] Specifically, in order to realize the telescopic movement of the drive shaft 22 relative to the output shaft 211 of the drive mechanism, the smart electric toothbrush also includes a limiting structure, which includes an inclined surface 311. The limiting structure is arranged near the connecting component 24, and the end of the connecting component 24 away from the drive shaft 22 is slidably connected to the inclined surface 311, so that under the drive mechanism, the drive shaft 22 rotates along its axis and drives the connecting component 24 to slide along the inclined direction of the inclined surface 311, so that under the sliding action of the connecting component 24, the drive shaft 22 is simultaneously displaced along the length direction of the drive shaft 22 (that is, one end of the drive shaft 22 undergoes telescopic movement relative to the drive mechanism). With the above design, the brush head skeleton can simultaneously rotate along the axis of the drive shaft 22 and displace along the length direction of the drive shaft 22, which helps the brush head skeleton to clean the teeth from multiple directions, effectively improving the cleaning efficiency of the smart electric toothbrush, and because the brush head skeleton can be displaced relative to the drive shaft 22, when using the smart electric toothbrush, the user does not need to manually move the smart electric toothbrush to adjust the brushing angle, which effectively improves the user's convenience.

[0067] For further information, see Figure 5 The smart electric toothbrush further comprises a fixing block 3, which is fixedly connected to the driving housing 23, and the limiting structure can be an inclined groove 31 opened on the fixing block 3, the inclined groove 31 is located outside the driving housing 23, the groove side of the inclined groove 31 is the above-mentioned inclined surface 311, and the connecting component 24 is slidably located in the inclined groove 31. The fixing block 3 comprises a top end and a bottom end, the bottom end of the fixing block is fixedly connected to the driving housing 23, and the groove direction of the inclined groove 31 is inclinedly set from the bottom end of the fixing block 3 to the bottom end of the fixing block 3. Specifically, when the connecting component 24 is a rod structure, the inclined groove 31 can be a through groove, and the connecting component 24 can reciprocate in the inclined groove 31 along the inclined surface 311; when the connecting component 24 is a pulley structure, the connecting component 24 includes a pulley and a pulley connecting rod, one end of the pulley connecting rod is fixedly connected to the drive shaft 22, and the other end of the pulley connecting rod is fixedly connected to the pulley, the inclined groove 31 is a blind groove, and the pulley reciprocates in the inclined groove 31 along the inclined surface 311.

[0068] As another optional implementation, Figure 7As shown, the smart electric toothbrush can also adopt a dual-drive solution, that is, the number of the driving mechanisms of the driving part 2 is two. Specifically, the structure of the driving part 2 can be: the driving mechanism includes a first driving mechanism 21a, a second driving mechanism 21b and a connecting rod mechanism 25, one end of the driving shaft 22 is connected to the first driving mechanism 21a, and the connecting rod mechanism 25 is connected between the first driving mechanism 21a and the second driving mechanism 21b. The first driving mechanism 21a is used to drive the driving shaft 22 to rotate along its own axis, thereby driving the brush head frame to rotate along the driving shaft 22; the second driving mechanism 21b drives the connecting rod mechanism 25 to drive the first driving mechanism 21a and the driving shaft 22 to displace along the length direction of the driving shaft 22, thereby driving the brush head frame to displace along the length direction of the driving shaft 22.

[0069] Furthermore, the driving mode of the first driving mechanism 21a and the second driving mechanism 21b can be intermittent driving or simultaneous driving. The intermittent driving mode means that a certain driving mechanism is driven once or multiple times for a period of time, and then stops driving for a period of time. Specifically, when the first driving mechanism 21a and the second driving mechanism 21b are driven simultaneously, the brush head skeleton can rotate along the axis of the driving shaft 22 and displace along the length direction of the driving shaft 22 at the same time. At this time, the brush head skeleton can clean the teeth from multiple directions at the same time, which is beneficial to improve the cleaning effect of the smart electric toothbrush.

[0070] When the first driving mechanism 21a and the second driving mechanism 21b are intermittently driven, the following situations can be considered:

[0071] First, the first driving mechanism 21a is continuously driven, and only the second driving mechanism 21b is intermittently driven, that is, the brush head skeleton rotates along the axis of the driving shaft 22 all the time, and at the same time, the brush head skeleton displaces intermittently along the length direction of the driving shaft 22;

[0072] Second, the second driving mechanism 21b is continuously driven, and only the first driving mechanism 21a is intermittently driven, that is, the brush head skeleton is always displaced along the length direction of the driving shaft 22, and the brush head skeleton is intermittently rotated along the axis of the driving shaft 22;

[0073] Third, the first driving mechanism 21a and the second driving mechanism 22b are both intermittently driven, so the driving shaft 22 can be driven only by the first driving mechanism 21a or only by the second driving mechanism 21b at certain times, and at this time, the brush head skeleton only moves in one direction; in addition, in other time periods, the driving shaft 22 can be driven by the first driving mechanism 21a and the second driving mechanism 21b at the same time, and at this time, the brush head skeleton moves at the same time;

[0074] Fourth, the first driving mechanism 21a and the second driving mechanism 21b are both intermittently driven, and the two are driven in turns, that is, after the first driving mechanism 21a drives for a period of time, the first driving mechanism 21a stops driving, and then the second driving mechanism 21b starts driving, and the second driving mechanism 21b drives for a period of time and then stops driving, thereby repeating the driving process of the first driving mechanism 21a and the second driving mechanism 21b.

[0075] Specifically, for the above four different intermittent driving conditions of the first driving mechanism 21a and the second driving mechanism 21b, the driving time of the first driving mechanism 21a and the second driving mechanism 21b can be preset to control the duration of each driving of the first driving mechanism 21a and the second driving mechanism 21b, so as to achieve the most scientific driving duration distribution.

[0076] For further information, see Figure 8 The connecting rod structure 25 includes a first connecting rod 251 and a second connecting rod 252. One end of the first connecting rod 251 is hinged to the first driving mechanism 21a, and the other end of the first connecting rod 251 is hinged to one end of the second connecting rod 252. The other end of the second connecting rod 252 is fixed to the second driving mechanism 21b. The second connecting rod 252 is used to drive the first connecting rod 251 and the first driving mechanism 21a to move along the length direction of the driving shaft 22 under the drive of the second driving mechanism 21b.

[0077] Further, the first driving mechanism 21a includes a bottom end 231 disposed away from the driving shaft 22, and a driving connecting member 231a disposed opposite to the bottom end 231 is fixedly disposed. When the number of the driving connecting member 231a is one, a first connecting groove 231b is provided on the end of the driving connecting member 231a away from the first driving mechanism 21a, and one end of the first connecting rod 251 is located in the first connecting groove 231b and is hinged to the two groove surfaces of the first connecting groove 231b; when the number of the driving connecting members 231a is two, the two driving connecting members 231a can be plate-like structures disposed at intervals, and one end of the first connecting rod 251 is hinged between the two driving connecting members 231a. A second connecting groove 252a is provided on the other end of the second connecting rod 252, and the other end of the first connecting rod 251 is located in the second connecting groove 252a and the first connecting rod 251 is hinged to the groove surface of the second connecting groove 252a. With the above-mentioned structural design, when setting the relative positions of the first driving mechanism 21a and the second driving mechanism 21b, the second driving mechanism 21b is set at the bottom end 231 of the driving housing 23 through the connecting rod mechanism 25, which is conducive to reasonably allocating the positions of the first driving mechanism 21a and the second driving mechanism 21b, and helps to make the internal structure of the smart electric toothbrush compact.

At the same time, the driving mechanism drives the driving shaft to drive the brush head frame to move, so that the first bristles and the second bristles can move relative to the teeth, further improving the cleaning efficiency and cleaning effect.

[0079] Embodiment 2

[0080] See also Fig. 9 , is a schematic diagram of the structure of an intelligent electric toothbrush provided by the present invention.
