Description

Technical Field

[0001] The present invention relates to the technical field of electric toothbrushes, and in particular to an omnidirectional electric toothbrush. Background Art

[0002] Electric toothbrushes are new products that have appeared in recent years and have set off a revolution in the field of oral health care abroad. Although the application of electric toothbrushes is not yet popular in China, some people have predicted that they will become an important member of mass health care products. This is because, compared with traditional manual toothbrushes, electric toothbrushes are driven by electricity and their brush heads can move at a speed of thousands or even tens of thousands of times per minute, making them much more efficient than manual toothbrushes.

[0003] Currently, there are two main types of smart toothbrushes on the market, one is the traditional brush head type, and the other is the braces type. Although the traditional brush head type smart toothbrush uses a motor to drive the brush head to rotate or swing at high speed, the user still needs to manually adjust the position of the brush head, which makes brushing troublesome.

[0004] Based on this, smart toothbrushes for braces came into being. Because the brush head of smart toothbrushes for braces is in a shape that matches the teeth, when brushing teeth, users only need to put the braces in their mouths and bite the braces to automatically complete brushing teeth. During the brushing process, users do not need to manually assist in adjusting the position of the brush head. The brushing method is simple and fast.

[0005] However, since the smart toothbrush with braces is driven by a single motor and in order to cover all teeth, its brush head is relatively large. When the user bites the brush head, the brush head can no longer swing due to the user's bite force and can only vibrate under the drive of the motor. The transmission of this vibration on the bristles is very weak, and the friction and vibration between the bristles on the brush head and the various surfaces of the teeth cannot be met, which leads to unsatisfactory brushing effect and efficiency, and poor user experience. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the present invention, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0036] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0039] The embodiment of the present invention discloses an omnidirectional electric toothbrush, which can transmit the power of a single driving mechanism to the bristles on the brush head, so as to ensure that the bristles have sufficient friction and vibration between the teeth, thereby improving the cleaning effect and efficiency of brushing teeth. The following will be described in detail with reference to the accompanying drawings.

[0040] See also Figure 1 , is a schematic structural diagram of an all-round electric toothbrush 100 provided in an embodiment of the present invention. The all-round electric toothbrush 100 includes a brush head part 1 and a driving part 2 fixedly connected to the brush head part 1. The brush head part 1 includes a brush head frame 11 and a plurality of bristle groups arranged on the brush head frame 11. The electric toothbrush 100 also includes a plurality of transmission mechanisms arranged corresponding to the bristle groups and arranged on the brush head frame 11, one of the transmission mechanisms is connected to the driving part 2, two adjacent transmission mechanisms are connected in transmission, and each transmission mechanism is used to connect each bristle group respectively, so as to realize that the power of the driving part 2 is transmitted to each bristle group respectively, thereby driving each bristle group to move.

[0041] It can be seen that by adopting the solution of the present invention, under the design of a single driving mechanism, it is also possible to utilize the transmission mechanism to realize the transmission of power to the driving part 2, so that each bristle group located on the brush head frame 11 can be driven by the power to achieve movement, reducing the vibration attenuation of the process from the driving mechanism to the bristle group, and then realizing the friction and vibration of the bristle group on the teeth when brushing, effectively improving the brushing efficiency and brushing effect.

[0042] In this embodiment, in order to improve the convenience and efficiency of brushing teeth, the brush head frame 11 can be a U-shaped frame or an H-shaped frame, etc., which can achieve full coverage of all teeth of the user. Preferably, this embodiment uses the brush head frame 11 as a U-shaped frame as an example for explanation. It can be understood that in other embodiments, the brush head frame 11 can also be a common strip frame, a circular frame or an elliptical frame, etc.

[0043] like Figures 2 to 4As shown, in this embodiment, an engagement space 11a for teeth to engage is formed on the brush head frame 11, each bristle group is arranged in the engagement space 11a, and each transmission mechanism is arranged outside the engagement space 11a, and is respectively arranged corresponding to the position of each bristle group. Specifically, since the brush head frame 11 can be a U-shaped frame, the engagement space 11a can be a U-shaped engagement space 11a formed on the brush head frame 11. When brushing teeth, the user only needs to place the teeth in the engagement space 11a, so that each bristle group in the engagement space 11a can contact the teeth and generate movement under the drive of the driving part 2, thereby achieving cleaning of different parts of the teeth in the engagement space 11a (such as the inner and outer surfaces of the teeth).

[0044] Furthermore, the brush head frame 11 is provided with an engagement groove extending along the extension direction of the brush head frame 11 itself, and the interior of the engagement groove forms the above-mentioned engagement space 11a. In other words, the engagement space 11a is formed by providing the engagement groove on the brush head frame 11, and the above-mentioned bristle group is located in the engagement groove, and the transmission mechanism is located outside the engagement groove. Specifically, because the brush head frame 11 is a U-shaped frame, the engagement groove is also a U-shaped groove provided on the brush head frame 11, and in order to adapt to the user's teeth and be able to fully accommodate the user's teeth, the extension length of the engagement groove on the brush head frame 11 is slightly greater than the length of the user's entire row of teeth.

[0045] Furthermore, the brush head frame 11 includes a first frame 11b and a second frame 11c connected to the first frame 11b, and the bite space 11a is formed on both the second frame 11c and the first frame 11b, and the opening direction of the bite space 11a located on the first frame 11b is opposite to the opening direction of the bite space 11a located on the second frame 11c. Specifically, the bite spaces 11a formed on the first frame 11b and the second frame 11c are respectively used to correspond to the upper teeth and lower teeth of the user, that is, when using the electric toothbrush 100 of the present invention, the upper teeth can be placed in the bite space 11a of the second frame 11c, and the lower teeth can be placed in the bite space 11a of the first frame 11b, so that the bristle groups located in the bite space 11a of the first frame 11b and the second frame 11c can be used to clean the various surfaces of the upper teeth (such as the inner and outer surfaces and the bite surface) and the various surfaces of the lower teeth (such as the inner and outer surfaces and the bite surface), thereby achieving coverage of various surfaces of the teeth, which is beneficial to improving the brushing efficiency.

[0046] Furthermore, in order to clean different surfaces of teeth, each bristle group may include a first bristle group 12a and a second bristle group 12b, wherein the first bristle group 12a is used to clean the inner and outer surfaces of teeth, and the second bristle group 12b is used to clean the occlusal surface of teeth. Since each transmission mechanism is respectively arranged corresponding to each bristle group, each transmission mechanism includes a first transmission mechanism 31 and a second transmission mechanism 32, wherein the first transmission mechanism 31 is arranged corresponding to the first bristle group 12a and is fixedly connected to the first bristle group 12a, and the second transmission mechanism 32 is arranged corresponding to the second bristle group 12b and is fixedly connected to the second bristle group 12b, thereby realizing the transmission of the power of the driving part 2 to the first bristle group 12a via the first transmission mechanism 31, and the transmission of the power of the driving part 2 to the second bristle group 12b by the second transmission mechanism 32, thereby realizing the friction and vibration of the first bristle group 12a and the second bristle group 12b on different surfaces of teeth.

[0047] Among them, as an optional embodiment, at least one of the first transmission mechanisms 31 can be connected to the driving part 2, and the second transmission mechanism 32 can be connected to the first transmission mechanism 31, so that the power of the driving part 2 can be transmitted to the first brush group 12a and the second transmission mechanism 32 through the first transmission mechanism 31, and then the second transmission mechanism 32 can also transmit the power of the driving part 2 to the second brush group 12b.

[0048] As another optional embodiment, at least one of the second transmission mechanisms 32 can be connected to the driving part 2, and the second transmission mechanism 32 can be connected to the first transmission mechanism 31 at the same time, so as to achieve the effect of transmitting the power of the driving part 2 to the first transmission mechanism 31 through the second transmission mechanism 32.

[0049] Specifically, since the brush head frame 11 can be a U-shaped frame, the first frame 11b and the second frame 11c are also U-shaped frames. In addition, since the second frame 11c and the first frame 11b are actually the same in structure, the following only takes the first frame 11b as an example to describe its specific structure in detail.

[0050] Specifically, Figure 2 As shown, the first frame 11b is provided with an engagement groove for teeth to engage with, and the engagement space 11a is formed inside the engagement groove.

[0051] The occlusal groove includes two side surfaces 111 that are oppositely arranged inside, and the two side surfaces 111 are both arc-shaped surfaces. A plurality of the first bristle groups 12a are arranged on the two side surfaces 111, and the bristle extension direction of the first bristle group 12a located on one of the side surfaces 111 and the bristle extension direction of the first bristle group 12a located on the other side surface 111 are arranged to face each other. In this way, when the teeth are located in the occlusal space 11a, the first bristle groups 12a facing each other can clean the inner and outer surfaces of the teeth respectively, thereby achieving cleaning of different parts of the teeth at the same time, and the cleaning efficiency is high. More specifically, the first bristle group 12a located on one of the side surfaces 111 is used to clean the inner surface of the teeth (i.e., the inner tooth surface), and the first bristle group 12a located on the other side surface 111 is used to clean the outer surface of the teeth (i.e., the outer tooth surface).

[0052] Preferably, in order to facilitate the arrangement of the first bristle group 12a on the two side surfaces 111 in the occlusal space 11a, a plurality of first positioning holes 111a are provided on the two side surfaces 111, and the plurality of first positioning holes 111a are arranged in sequence along the extension direction of the side surface 111, so that the position of the first bristle group 12a on the side surface 111 can be positioned through the first positioning holes 111a, and at the same time, it can also ensure that the arrangement of the first bristle group 12a on the side surface 111 can also be arranged in sequence along the extension direction of the side surface 111, thereby ensuring that each tooth can contact the first bristle group 12a. It is understandable that when arranging, the spacing between two adjacent first bristle groups 12a on the same side surface 111 can be adjusted with reference to the spacing between two adjacent teeth.

[0053] Furthermore, the first frame 11b also includes two outer wall surfaces 112 located outside the bite groove, wherein one outer wall surface 112 is arranged opposite to one of the side surfaces 111, and the other outer wall surface 112 is arranged opposite to the other side surface 111. Since each first transmission mechanism 31 is arranged corresponding to each first bristle group 12a, a plurality of first transmission mechanisms 31 are arranged on the two outer wall surfaces 112, and the positions of the first transmission mechanisms 31 located on the two outer wall surfaces 112 correspond to the positions of the first bristle groups 12a located on the two side surfaces 111, so that each first transmission mechanism 31 corresponds to each first bristle group 12a and is fixedly connected to each first bristle group 12a, thereby enabling the first transmission mechanism 31 to transmit the driving power to each first bristle group 12a. It should be known that two adjacent first transmission mechanisms 31 located on any outer wall surface 112 should be connected in transmission. In this way, when one of the first transmission mechanisms 31 is connected to the driving part 2, the power of the driving part 2 can be transmitted to each first transmission mechanism 31 by utilizing the one of the first transmission mechanisms 31, thereby eliminating the need for each first transmission mechanism 31 to be connected to the driving part 2, thereby facilitating the structural design of the electric toothbrush 100.

[0054] Furthermore, if Figures 2 to 4 As shown, since the first transmission mechanism 31 is provided on both the first frame 11b and the second frame 11c, at least one of the first transmission mechanisms 31 located on the first frame 11b and at least one of the first transmission mechanisms 31 located on the second frame 11c are connected to the driving part 2, so that the power of the driving part 2 is transmitted to other first transmission mechanisms 31 located on the first frame 11b through at least one of the first transmission mechanisms 31 located on the first frame 11b, and the power of the driving part 2 is transmitted to other first transmission mechanisms 31 located on the second frame 11c through at least one of the first transmission mechanisms 31 located on the second frame 11c.

[0055] In this embodiment, the occlusal space 11a further includes an occlusal bottom surface 113 (i.e., the bottom surface of the occlusal groove), on which a plurality of second bristle groups 12b are arranged, and the electric toothbrush 100 further includes a plurality of second transmission mechanisms 32 located outside the occlusal space 11a, each second transmission mechanism 32 is respectively arranged corresponding to each second bristle group 12b and is fixedly connected to each second bristle group 12b, and each second transmission mechanism 32 is respectively connected to each first transmission mechanism 31 in transmission. Specifically, the second bristle groups 12b are arranged on the occlusal bottom surface 113 in a sequential arrangement along the extension direction of the occlusal bottom surface 113, and the spacing between two adjacent second bristle groups 12b can also be set with reference to the spacing between two adjacent first bristle groups 12a. Preferably, each second bristle group 12b is located between two first bristle groups 12a disposed toward each other, and the extension direction of the bristles on each second bristle group 12b is perpendicular to the extension direction of the bristles on each first bristle group 12a. That is to say, the bristles of the second bristle group 12b extend upward along the occlusal bottom surface 113, while the bristles of the first bristle group 12a extend in a direction parallel to the occlusal bottom surface 113. It can be seen that the second bristle group 12b can be used to clean the molar surface of the teeth (i.e., the occlusal surface of the teeth), while the first bristle groups 12a on both sides are used to clean the inner and outer surfaces of the teeth, respectively. Therefore, when the electric toothbrush 100 of the present invention is used, when the teeth are placed in the occlusal space 11a, the first bristle group 12a and the second bristle group 12b can be used to simultaneously clean different parts of the teeth, so that the user does not need to manually adjust the brushing angle and brushing position, and the brushing method is simpler and more convenient.

[0056] Furthermore, since each second transmission mechanism 32 is respectively arranged corresponding to each second bristle group 12b, the plurality of second transmission mechanisms 32 are arranged on the lower surface of the first frame 11b opposite to the occlusal bottom surface 113, and each second transmission mechanism 32 can extend from the lower surface to the outer wall surface 112 of the first frame 11b and be connected to the first transmission mechanism 31 located on the outer wall surface 112. Thus, the power of the driving part 2 can be transmitted to the second transmission mechanism 32 through the first transmission mechanism 31, thereby achieving the effect of transmitting the power to the second bristle group 12b through the second transmission mechanism 32.

[0057] In this embodiment, in order to reduce the number of second transmission mechanisms 32, the second bristle group 12b on the first frame 11b can be extended to the occlusal bottom surface 113 of the second frame 11c, that is, the second bristle group 12b on the occlusal bottom surface 113 of the first frame 11b and the second bristle group 12b on the occlusal bottom surface 113 of the second frame 11c are a common bristle group. The specific implementation method can be: a plurality of second positioning holes 113a are opened on the occlusal bottom surface 113 of the first frame 11b and penetrate to the occlusal bottom surface 113 of the second frame 11c, and each second bristle group 12b is positioned and installed on the occlusal bottom surface 113 through each second positioning hole 113a, and it is necessary to ensure that the bristles of each second bristle group 12b can protrude from the occlusal bottom surface 113. Such a configuration can not only reduce the number of second transmission mechanisms 32 but also reduce the number of second bristle groups 12b, thereby saving material and equipment costs and reducing the difficulty of assembling components.

[0058] Furthermore, if Figure 3 and Figure 4 As shown, when the first frame 11b is connected to the second frame 11c, the first transmission mechanism 31 located outside the engagement space 11a of the first frame 11b is arranged in a U-shape along the extension direction of the first frame 11b, and the first transmission mechanism 31 located outside the engagement space 11a of the second frame 11c is also arranged in a U-shape along the extension direction of the second frame 11c, that is, each first transmission mechanism 31 located on the first frame 11b is respectively arranged corresponding to each first transmission mechanism 31 located on the second frame 11c, and each second transmission mechanism 32 is transmission-connected to each first transmission mechanism 31 located on the first frame 11b and each first transmission mechanism 31 located on the second frame 11c, and is located between the two first transmission mechanisms 31. It should be known that, in the present embodiment, the first transmission mechanism 31 located on the first frame 11b and the first transmission mechanism 31 located on the second frame 11c are not in contact with each other, and since the second transmission mechanism 32 is transmission-connected between the upper and lower first transmission mechanisms 31, therefore, in the present solution, one of the first transmission mechanisms 31 located on the first frame 11b and one of the first transmission mechanisms 31 located on the second frame 11c can be connected to the driving part 2, and then the second transmission mechanism 32 can be transmission-connected to the two first transmission mechanisms 31, thereby realizing the power transmission of the driving part 2.

[0059] In this embodiment, the first transmission mechanism 31 and the second transmission mechanism 32 can both be gear transmission mechanisms, and the transmission connection between two adjacent first transmission mechanisms 31 means that the two adjacent gear transmission mechanisms are meshed with each other. The transmission connection between the second transmission mechanism 32 and the two first transmission mechanisms 31 means that the gears of the second transmission mechanism 32 are meshed with the gears of the two first transmission mechanisms 31. The movement direction of each first transmission mechanism 31 located on the first frame 11b is the same as the movement direction of the corresponding first transmission mechanism 31 located on the second frame 11c, and the movement direction of the second transmission mechanism 32 located between the upper and lower first transmission mechanisms 31 is opposite to the movement direction of the upper and lower first transmission mechanisms 31. In addition, it should be known that the number of teeth of each first transmission mechanism 31 can be the same or different. When the number of teeth of each first transmission mechanism 31 is the same, the movement speed of the first bristle group 12a driven by it is the same. When the number of teeth of each first transmission mechanism 31 is different, the rotation speed of the one with fewer teeth is faster, and the rotation speed of the one with more teeth is slower. Therefore, the rotation speed of different first bristle groups 12a can be adjusted by the number of teeth of the first transmission mechanism 31, so that adaptive adjustment can be made for the tooth positions that require greater cleaning force, and the brushing effect is better. Similarly, the same is true for the second transmission mechanism 32. The number of teeth of each second transmission mechanism 32 can be the same or different. The rotation speed of the second bristle group 12b can also be adjusted by adjusting the number of teeth of the second transmission mechanism 32.

[0060] Furthermore, since the first transmission mechanism 31 and the second transmission mechanism 32 are both gear transmission mechanisms, and since the second transmission mechanism 32 is transmission-connected between the two first transmission mechanisms 31, the movement direction of the first bristle group 12a is set opposite to the movement direction of the second bristle group 12b. For example, when the first bristle group 12a moves along the first direction, the second bristle group 12b should move along the second direction. The first direction may be clockwise, and the second direction may be counterclockwise.

[0061] Please also read Figures 5 to 7In the present embodiment, the brush head frame 11 further comprises a cover 11d connected to the first frame 11b and the second frame 11c. The cover 11d covers the outside of the first frame 11b and the second frame 11c and is used to cover the first transmission mechanism 31 and the second transmission mechanism 32 located outside the engagement space 11a. Specifically, the cover body 11d includes a first cover body 115 and a second cover body 116, and the first cover body 115 covers the U-shaped recesses of the first frame 11b and the second frame 11c, and is used to cover the first transmission mechanism 31 and the second transmission mechanism 32 located at the U-shaped recesses of the first frame 11b and the second frame 11c, and this part of the first transmission mechanism 31 and the second transmission mechanism 32 are used to transmit the power of the driving part 2 to the first bristle group 12a and the second bristle group 12b located on one of the side surfaces 111 of the occlusal space 11a of the first frame 11b and the second frame 11c, so that this part of the first bristle group 12a and the second bristle group 12b can clean the inner surface (i.e., the inner tooth surface) and the occlusal surface of the teeth. Similarly, the second cover body 116 covers the position of the first frame 11b and the second frame 11c opposite to the U-shaped recess, and is used to cover the first transmission mechanism 31 and the second transmission mechanism 32 located at this position, and this part of the first transmission mechanism 31 and the second transmission mechanism 32 are used to transmit the power of the driving part 2 to the first bristle group 12a and the second bristle group 12b on the other side 111 of the occlusal space 11a of the first frame 11b and the second frame 11c, and this part of the first bristle group 12a and the second bristle group 12b are used to clean the outer surface of the teeth (i.e., the outer tooth surface) and the occlusal surface, respectively. Preferably, the first cover 115 and the second cover 116 can be connected to the first frame 11b and the second frame 11c in a detachable manner such as screw fixing or snap fixing, so that when any of the first transmission mechanism 31 or the second transmission mechanism 32 fails, the user can check the operation of the first transmission mechanism 31 and the second transmission mechanism 32 by separating the first cover 115 or the second cover 116 from the first frame 11b and the second frame 11c. It is understandable that in other embodiments, the first cover 115 and the second cover 116 can also be fixedly connected to the first frame 11b and the second frame 11c by gluing or welding.

[0062] In this embodiment, the first bristle group 12a includes a first bristle carrier 121 and first bristles 122 arranged on the first bristle carrier 121. The first bristle carrier 121 may be a carrier plate, on which a plurality of openings (not shown) may be arranged, and each first bristle 122 is arranged corresponding to each opening, so as to fix the first bristle 122 on the first bristle carrier 121. Specifically, in order to facilitate connection with the first positioning hole 111a in the occlusal space 11a, a positioning shaft 121a may be arranged on the first bristle carrier 121, and the positioning shaft 121a is passed through the first positioning hole 111a, so as to realize the positioning of the first bristle group 12a in the occlusal space 11a.

[0063] Further, the first transmission mechanism 31 is fixedly connected to the positioning shaft 1211. Specifically, the positioning shaft 1211 is inserted into the first transmission mechanism 31 and is fixedly connected to the first transmission mechanism 31 by glue bonding, ultrasonic welding or screw fixing, so as to avoid the positioning shaft 1211 and the first transmission mechanism 31 from loosening or falling off during the movement, and ensure that the first transmission mechanism 31 can transmit the power of the driving part 2 to the positioning shaft 1211, and then transmit it to the first bristles 122 through the positioning shaft 1211. It can be understood that in other embodiments, the first transmission mechanism 31 can also be integrally formed with the positioning shaft 1211.

[0064] Furthermore, the first bristles 122 can be hard bristles or soft bristles. Preferably, the first bristles 122 are hard bristles, such as nylon yarn, Dupont yarn, etc., so that the inner and outer surfaces of the teeth can be strongly cleaned.

[0065] In the present embodiment, the second bristle group 12b includes a second bristle carrier (not marked) and second bristles (not marked), and the second bristle carrier may be a cylindrical structure, and the second bristles are arranged on the outer surface of the second bristle carrier. Specifically, in order to facilitate the positioning of the second bristle group 12b on the occlusal bottom surface 113, positioning posts (not marked) are respectively arranged on both end surfaces of the second bristle carrier, and the positioning post located on one end of the second bristle carrier is penetrated through the occlusal bottom surface 113 of the first frame 11b, and the positioning post located on the other end of the second bristle carrier is penetrated through the occlusal bottom surface 113 of the second frame 11c, so that the second bristles can extend from the occlusal bottom surface 113 of the first frame 11b to the occlusal bottom surface 113 of the second frame 11c, so that the second bristle group 12b can be shared by the first frame 11b and the second frame 11c.

[0066] Furthermore, the second transmission mechanism 32 is fixedly connected to one of the positioning columns, so that the power of the driving part 2 is transmitted to the second bristles through the second transmission mechanism 32 .

[0067] Furthermore, the material of the second bristles can be the same as or different from that of the first bristles 122. For example, the second bristles can be hard bristles the same as the first bristles 122 or soft bristles different from the first bristles 122. Preferably, the material of the second bristles is different from that of the first bristles 122, and the second bristles are soft bristles, such as soft silicone bristles.

[0068] Please refer again Figures 1 to 4 In this embodiment, the brush head part 1 also includes a transmission shaft 4, which is located in the brush head frame 11, and one end of the transmission shaft 4 is fixed to the driving part 2, and the other end of the transmission shaft 4 is connected to the transmission mechanism to achieve the transmission of the power of the driving part 2 to the transmission mechanism. Specifically, the transmission shaft 4 is connected to any one of the second transmission mechanisms 32, and since the second transmission mechanism 32 is a gear transmission mechanism, a first gear 41 may be provided on the transmission shaft 4, and the transmission shaft 4 is provided on the other end of the transmission shaft 4 for meshing connection with one of the first transmission mechanisms 31 (i.e., the gear transmission mechanism). Preferably, one of the first transmission mechanisms 31 may be a first transmission mechanism 31 located at the center of the brush head frame 11, and the transmission shaft 4 is also located at the center of the brush head frame 11.

[0069] Furthermore, since the brush head frame 11 includes a first frame 11b and a second frame 11c, and the first frame 11b and the second frame 11c are both provided with a first transmission mechanism 31, and there is no direct transmission relationship between the first transmission mechanism 31 located on the first frame 11b and the first transmission mechanism 31 located on the second frame 11c, therefore, in the actual structure, the transmission shaft 4 should be simultaneously connected to one of the first transmission mechanisms 31 located on the first frame 11b and one of the first transmission mechanisms 31 located on the second frame 11c.

[0070] Furthermore, since the first transmission mechanism 31 and the second transmission mechanism 32 are not only located at the U-shaped recesses of the first frame 11b and the second frame 11c, but also located at the positions of the first frame 11b and the second frame 11c opposite to the U-shaped recesses, a second gear 42 should be provided on the transmission shaft 4, wherein the first gear 41 is used for transmission connection with the first transmission mechanism 31 located at the positions of the first frame 11b and the second frame 11c opposite to the U-shaped recesses thereof, and the second gear 42 is used for transmission connection with the first transmission mechanism 31 located at the U-shaped recesses of the first frame 11b and the second frame 11c. Thus, the first gear 41 can be located at one end of the transmission shaft 4 away from the driving mechanism, and the second gear 42 can be located at one end of the transmission shaft 4 away from the driving mechanism.

[0071] In this embodiment, the driving part 2 may include a housing 21 and a driving mechanism 22 disposed in the housing 21. The output shaft of the driving mechanism 22 extends from the housing 21 to the inside of the brush head frame 11 and is fixedly connected to the transmission shaft 4. Specifically, the housing 21 may be used to form the handle of the electric toothbrush 100 for the user to hold and use. The driving mechanism 22 may be a micro motor disposed in the housing 21, and is used to provide power for the brush head part 1 to vibrate.

[0072] Furthermore, the housing 21 may include an upper shell 21a and a lower shell 21b. The lower shell 21b and the upper shell 21a may be connected together by threaded connection, snap connection, glue bonding or ultrasonic welding, and an internal space for placing the driving mechanism 22 is formed inside the lower shell 21b.

[0073] Furthermore, a hollow fixing frame 211 may be provided in the outer shell 21b, and the fixing frame 211 is fixed inside the lower shell 21b, and the driving mechanism 22 is provided in the hollow part of the fixing frame 211 to realize the positioning and fixing of the driving mechanism 22 inside the lower shell 21b.

[0074] Furthermore, in order to facilitate the connection between the brush head part 1 and the driving part 2, a connecting seat 11e can be provided on the brush head frame 11, and the connecting seat 11e is arranged toward the outer shell 21 and forms a gap with the outer shell 21, and the interior of the connecting seat 11e is connected with the interior of the brush head frame 11, and one end of the output shaft of the driving mechanism 22 extends into the interior of the connecting seat 11e and extends to the interior of the brush head frame 11 to connect with the transmission mechanism. Specifically, the transmission shaft 4 is located in the connecting seat 11e, and one end of the output shaft of the driving mechanism 22 extends into the interior of the connecting seat 11e and is connected to one end of the transmission shaft 4, and the other end of the transmission shaft 4 extends from the interior of the connecting seat 11e to the interior of the brush head frame 11 and is connected to the first transmission mechanism 31.

[0075] Specifically, the specific working process of the electric toothbrush 100 during brushing is as follows:

[0076] First, insert the teeth into the occlusal space 11a and start the driving mechanism 22. The driving mechanism 22 drives the transmission shaft 4 to move, so that the power part of the driving mechanism 22 is transmitted to the first transmission mechanism 31 through the transmission shaft 4, and then transmitted to the second transmission mechanism 32 via the first transmission mechanism 31. Therefore, the first bristle group 12a and the second bristle group 12b fixedly connected to the first transmission mechanism 31 and the second transmission mechanism 32 can be driven by the corresponding first transmission mechanism 31 and the second transmission mechanism 32 to vibrate, thereby cleaning the inner and outer surfaces and occlusal surfaces of the teeth.

[0077] It should be known that the movement duration of the drive mechanism 22 can be set in advance according to the user's usage habits, for example, it can be set to 10s, 20s or 30s, so that the drive mechanism 2220 will automatically stop after 10s, 20s or 30s of starting, which means that the user has finished brushing their teeth. Of course, the user can also control the start time of the drive mechanism 22 at any time. For example, after the drive mechanism 22 is started, the user can control the stop or restart of the drive mechanism 22 by controlling the control button of the drive mechanism 22.

[0078] The omnidirectional electric toothbrush provided in the embodiment of the present invention is provided with a plurality of first transmission mechanisms which are sequentially connected to each other and a plurality of second transmission mechanisms which are connected to each other in transmission on the brush head frame, and the first transmission mechanism is correspondingly provided and connected to the first bristle group, and the second transmission mechanism is correspondingly provided and connected to the second bristle group, and at the same time the first transmission mechanism is connected to the driving part through the transmission shaft, so that the power of the driving part is transmitted to the first bristle group, the second transmission mechanism and the second bristle group through the first transmission mechanism, so that even when a single driving mechanism is used and the driving mechanism is far away from the brush head frame, the power of the driving part can be transmitted to the second bristle group and the first bristle group via the second transmission mechanism and the first transmission mechanism, which effectively solves the problem that the transmission of the motor of the traditional braces-type smart toothbrush on the bristles is very weak and cannot meet the friction and vibration between the bristles and the various surfaces of the teeth, and is conducive to improving the cleaning effect and brushing efficiency of teeth.

[0079] In addition, the electric toothbrush adopts a first transmission mechanism and a second transmission mechanism, both of which are arranged inside the brush head frame, which can effectively avoid the problem of water ingress into the first transmission mechanism and the second transmission mechanism causing operating failures, which is beneficial to improving the waterproof performance and service life of the electric toothbrush.
