[0051] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] The electronic brush head 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0053] like Figure 1-Figure 18 As shown, the electronic brush head 1 according to the embodiment of the present utility model comprises a carrier 10, bristles and electrical components.

[0054] The electronic brush head 1 is used for an electric toothbrush 1000. The carrier 10 is provided with a socket 121. The socket 121 is suitable for the connecting shaft 51 of the brush handle 5 to be inserted to connect with the brush handle 5. The bristles are arranged on the carrier 10. When using the electric toothbrush 1000, the user can hold the brush handle 5, and the brush handle 5 drives the carrier 10 to move, thereby driving the bristles to move, and using the bristles to clean the teeth.

[0055] The electrical component is arranged on the carrier 10, and the electrical component includes an electrical functional part 32 and a first electrical connecting part 33. The electrical functional part 32 is arranged inside the carrier 10 and / or exposed on the surface of the carrier 10. The electrical functional part 32 takes effect at the position corresponding to the bristles, so that when the user uses the bristles to clean the teeth, the electrical functional part 32 can provide the user with additional effects through the bristles, such as providing additional effects such as whitening teeth, observing the inside of the oral cavity, and deep cleaning of the teeth.

[0056] Among them, the electrical functional component 32 can be a light-emitting component, which uses light to achieve whitening, cleaning and other effects on teeth; the electrical functional component 32 can also be a radio frequency electrode, which can emit radio frequency current, and then generate charged particles to decompose tooth stains or decompose dental plaque and tartar; the electrical functional component 32 can also be an electrolytic electrode, which can ionize water or toothpaste to produce cleaning molecules, and use electricity to adsorb the cleaning molecules to the teeth; the electrical functional component 32 can also be a heating wire, which can be used to atomize water or toothpaste to promote the release of cleaning factors in the toothpaste, and can also dry and sterilize the bristles; the electrical functional component 32 can also be a camera, and when the user uses the electric toothbrush 1000, the electrical functional component 32 can be used to take pictures of the inside of the mouth. Of course, the electrical functional component 32 can also be other structures that provide beneficial effects for oral health, and there are no excessive restrictions here.

[0057] The electric function part 32 is electrically connected to the first electric connection part 33, and the first electric connection part 33 is arranged inside the carrier 10 to protect the first electric connection part 33 and prevent the components in the external environment from scratching the first electric connection part 33 and causing damage to the first electric connection part 33. The first electric connection part 33 is suitable for forming a detachable contact connection with the second electric connection part 52 of the brush handle 5 to realize the detachable cooperation between the electronic brush head 1 and the brush handle 5, thereby facilitating the regular replacement of the electronic brush head 1 or the regular cleaning of the brush head.

[0058] Among them, when the electronic brush head 1 is matched with the brush handle 5, the connecting shaft 51 is inserted into the socket 121 to connect with the brush handle 5. At the same time, the second electrical connector 52 on the connecting shaft 51 is located in the socket 121 to be electrically connected to the first electrical connector 33 in the carrier 10. In this way, the carrier 10 can protect the first electrical connector 33 and the second electrical connector 52. On the one hand, it can prevent components in the external environment from scratching the first electrical connector 33 and the second electrical connector 52, affecting the electrical connection between the first electrical connector 33 and the second electrical connector 52. On the other hand, it can provide a relatively sealed working environment for the first electrical connector 33 and the second electrical connection 52. It is not easy for external water to reach the inside of the socket 121, so as to reduce the probability of water reaching the contact and matching area of ​​the first electrical connector 33 and the second electrical connection 52, and reduce the risk of short circuit between the first electrical connector 33 and the second electrical connection 52.

[0059] In addition, the first electrical connection 33 and the second electrical connection 52 are contact connections, which are more stable than wireless connections and other connection methods, so that when the brush handle 5 drives the electronic brush head 1 to vibrate at high frequency, the first electrical connection 33 and the second electrical connection 52 can also maintain a stable electrical connection.

[0060] At the same time, when the user needs to remove the electronic brush head 1 from the brush handle 5, the first electrical connector 33 is separated from the second electrical connector 52, so that the carrier 10 together with the electrical components can be removed from the brush handle 5. Since the bristles and the electrical components are both arranged in the carrier 10, the electrical components and the bristles always remain relatively still. In this way, when the relative position of the electronic brush head 1 and the brush handle 5 changes, the electrical functional component 32 can still stably apply energy to the corresponding position of the bristles, thereby avoiding the electrical functional component 32 being blocked by the bristles, so that the electrical functional component 32 can stably exert its effect at the corresponding position of the bristles.

[0061] According to the electronic brush head 1 of the embodiment of the utility model, the first electrical connector 33 and the second electrical connector 52 complete the contact electrical connection inside the carrier 10, so that the first electrical connector 33 and the second electrical connector 52 are protected by the carrier 10, and the external water is not easy to reach the inside of the socket 121, so as to reduce the probability of water reaching the contact matching area of ​​the first electrical connector 33 and the second electrical connector 52, reduce the risk of short circuit between the first electrical connector 33 and the second electrical connector 52, and facilitate the stable connection of the first electrical connector 33 and the second electrical connector 52.

[0062] The electronic brush head 1 according to a specific embodiment of the present utility model is described below with reference to the accompanying drawings.

[0063] In some specific embodiments of the present invention, Figure 1-Figure 18 As shown, the electronic brush head 1 includes a carrier 10, bristles and electrical components.

[0064] In some embodiments of the present invention, Figure 5 , Fig.12 As shown, the electrical components include a circuit board 31, a first electrical connector 33 is provided on the circuit board 31, the electrical functional component 32 is electrically connected to the circuit board 31, the brush handle 5 supplies power to the circuit board 31 through the second electrical connector 52 and the first electrical connector 33, the circuit board 31 supplies power to the electrical functional component 32 and transmits information to the electrical functional component 32, so that the electrical functional component 32 can take effect at the corresponding position of the bristles, thereby meeting the user's multi-functional requirements for the electric toothbrush 1000.

[0065] Specifically, the electrical functional component 32 in the related art is arranged at the electronic brush head 1, and there is a certain distance between the electrical functional component 32 and the brush handle 5. When the electronic brush head 1 has multiple electrical functional components 32, if each electrical functional component 32 is electrically connected to the brush handle 5 one by one, due to the long distance between the electrical functional component 32 and the brush handle 5, the electrical connection is more complicated, and when using wires to realize the electrical connection between the electrical functional component 32 and the brush handle 5, due to the long length and large number of wires, too much space in the electric toothbrush 1000 will be occupied.

[0066] In this solution, a circuit board 31 is set up, so that the circuit board 31 and the brush handle 5 are electrically connected to the circuit board 31 through the second electrical connector 52 and the first electrical connector 33, and the electrical functional component 32 is electrically connected to the circuit board 31. Since the circuit board 31 and the electrical functional component 32 are both arranged in the electronic brush head 1, the distance between the electrical functional component 32 and the circuit board 31 is short, so that the electrical functional component 32 and the circuit board 31 are electrically connected. The connection method is relatively simple, which is convenient for integrating multiple electrical functional components 32 on the circuit board 31, and is convenient for simplifying the electrical connection structure for electrically connecting multiple electrical functional components 32, thereby reducing the space occupied by the electrical connection structure for connecting the electrical functional component 32 in the electric toothbrush 1000.

[0067] In some embodiments, there are multiple electrical functional components 32, and the circuit board 31 is electrically connected to the electrical functional components 32 through an electrical connector to integrate the multiple electrical functional components 32 and the circuit board 31 together, wherein the electrical connection structure can be a wire, an electrical contact or a solder joint.

[0068] In some optional embodiments of the present invention, Figure 4 As shown, the first electrical connector 33 includes a contact point arranged on the circuit board 31. When the connecting shaft 51 of the brush handle 5 is inserted into the socket 121 and plugged into place, the contact point contacts and is electrically connected with the second electrical connector 52 on the connecting shaft 51 to realize the electrical connection between the circuit board 31 and the electrical functional part 32, so that the brush handle 5 can supply power to the circuit board 31. Since the circuit board 31 is electrically connected to the electrical functional part 32, the circuit board 31 can conduct electricity to the electrical functional part 32 and can transmit information to the electrical functional part 32, so that the electrical functional part 32 can work normally and the electrical functional part 32 can take effect at the corresponding position of the bristles.

[0069] In some specific embodiments of the present invention, the first electrical connector 33 includes multiple contact contacts, which are arranged on the same side of the circuit board 31 and are spaced apart in a direction perpendicular to the axial direction of the connecting shaft 51, so that when the first electrical connector 33 and the second electrical connector 52 are in contact and mating, the multiple contact contacts located on the same side are conveniently electrically connected to the second electrical connector 52, and the multiple contact contacts are spaced apart to keep a distance between the contact contacts, thereby avoiding electrical connection between the contact contacts and causing a short circuit.

[0070] The structure of arranging the first electrical connector 33 on the circuit board 31 is relatively simple, which is convenient for reducing the processing difficulty and improving the stability of the electrical connection between the circuit board 31 and the first electrical connector 33 .

[0071] In some embodiments, the axial direction of the circuit board 31 and the connecting shaft 51 extends in the vertical direction, and the width direction of the circuit board 31 extends in the horizontal direction. The first electrical connector 33 includes two contact contacts, and the two contact contacts are spaced apart along the width direction of the circuit board 31 to keep a distance between the two contact contacts, thereby avoiding electrical connection between the two contact contacts and causing a short circuit.

[0072] In some embodiments of the present invention, Fig.10 , Fig.11 As shown, the first electrical connector 33 includes a spring piece 341, which is exposed in the socket 121, so that the end of the spring piece 341 exposed from the socket 121 can be electrically connected to the electrical functional part 32 outside the socket 121, thereby enabling the brush handle 5 to supply power to the electrical functional part 32 through the first electrical connector 33 and the second electrical connector 52.

[0073] In some embodiments, the electronic brush head 1 also includes a circuit board 31, the electrical functional component 32 is electrically connected to the circuit board 31, the end of the spring 341 protruding from the socket 121 is used to be electrically connected to the circuit board 31, and the end of the spring 341 located in the socket 121 is used to be electrically connected to the second electrical connector 52 on the connecting shaft 51, so that the brush handle 5 can supply power to the circuit board 31 through the second electrical connector 52 and the first electrical connector 33, so that the circuit board 31 supplies power to the electrical functional component 32, so that the electrical functional component 32 can function.

[0074] In some optional embodiments of the present invention, there are multiple first electrical connectors 33 that are spaced apart to surround an insertion space 342, and the connecting shaft 51 is inserted into the insertion space 342 to achieve contact-type detachable cooperation between the second electrical connector 52 on the connecting shaft 51 and the first electrical connector 33, thereby achieving detachable cooperation between the connecting shaft 51 and the electronic brush head 1.

[0075] Among them, when the connecting shaft 51 is inserted into the insertion space 342, the second electrical connector 52 contacts and cooperates with multiple spring sheets 341. The multiple spring sheets 341 can clamp the second electrical connector 52 in the insertion space 342, thereby realizing the fixed connection between the second electrical connector 52 and the first electrical connector 33, and then fixing the end of the connecting shaft 51 extending into the socket 121, thereby realizing the detachable cooperation between the electronic brush head 1 and the connecting shaft 51.

[0076] like Fig.16As shown, in the present embodiment, the electrical component includes two spring pieces 341, and the two spring pieces 341 are arranged at intervals along the radial direction of the connecting shaft 51. The second electrical connecting part 52 includes a positive electrode connecting part and a negative electrode connecting part. When the connecting shaft 51 is inserted into the insertion space 342, one of the spring pieces 341 is in contact with and electrically connected to the positive electrode connecting part, and the other spring piece 341 is in contact with and electrically connected to the negative electrode connecting part, thereby forming a loop between the brush handle 5 and the electrical functional part 32 to supply power to the electrical functional part 32, so that the electrical functional part 32 can work normally to play a role at the corresponding position of the bristles.

[0077] At the same time, the two spring sheets 341 are arranged opposite to each other along the radial direction of the connecting shaft 51, so that when the connecting shaft 51 extends into the insertion space 342, the two spring sheets 341 can clamp the second electrical connector 52 on the connecting shaft 51, thereby limiting the position of the second electrical connector 52 and fixing the end of the connecting shaft 51, thereby realizing a fixed connection between the electronic brush head 1 and the brush handle 5.

[0078] In some embodiments, the electrical component may also include three spring clips 341. Correspondingly, the second electrical connector 52 includes not only a positive electrode connector and a negative electrode connector, but also a signal transmission part, wherein two spring clips 341 are respectively in contact with and electrically connected to the positive electrode connector and the negative electrode connector, and the remaining spring clip 341 is electrically connected to the signal transmission part, so that the signal at the brush handle 5 can be transmitted to the electrical functional part 32 through the signal transmission part, so that the electrical functional part 32 can work according to the signal, for example, start or stop working according to the signal, adjust the working intensity according to the signal, etc. Of course, the electrical component may also include four or five spring clips, and multiple spring clips are respectively electrically connected to the second electrical connector 52, and no excessive restrictions are made here.

[0079] In some specific embodiments of the present invention, Fig.16 As shown, each first electrical connector 33 includes an electrical connection end 343 in contact with the second electrical connector 52, and at least one first electrical connector 33 is provided with a guide portion 345, which extends obliquely in a direction away from the electrical connection end 343, and the guide portion 345 is used to guide the second electrical connector 52 to the insertion space 342. When the connecting shaft 51 is inserted into the socket 121, the guide portion 345 can guide the movement of the second electrical connector 52, so that the second electrical connector 52 can be smoothly moved into the plug-in space, thereby realizing a smooth electrical connection between the second electrical connector 52 and the electrical connection end 343. At the same time, when guiding the movement of the second electrical connector 52, the movement of the connecting shaft 51 can be guided, so that the connecting shaft 51 can be smoothly inserted into the socket 121, thereby realizing the plug-in fit between the electronic brush head 1 and the brush handle 5.

[0080] like Fig.16As shown, in this embodiment, the electrical component includes two first electrical connectors 33, and the two first electrical connectors 33 are arranged at intervals along the radial direction of the connecting shaft 51. Each first electrical connector 33 is provided with a guide portion 345. Since the guide portion 345 extends obliquely in a direction away from the power connection end 343, in the radial direction of the connecting shaft 51, the distance between the ends of the two guide portions 345 toward the brush handle 5 is greater than the distance between the two guide portions 345 and the connection to the power connection end 343, so that the second electrical connector 52 can easily enter the insertion space 342, and at the same time, the moving direction of the second electrical connector 52 can be guided so that the second electrical connector 52 moves in a direction close to the power connection end 343, so as to achieve smooth cooperation between the second electrical connector 52 and the power connection end 343.

[0081] In some specific embodiments of the present invention, Fig.16 As shown, each first electrical connector 33 includes an electrical connection end 343 in contact with the second electrical connector 52. In the axial direction of the connecting shaft 51, at least two electrical connection ends 343 are spaced apart to space the two electrical connection ends 343 radially along the connecting shaft 51, thereby facilitating further spacing of the two electrical connection ends 343 to avoid connection between the two electrical connection ends 343 and avoid causing a short circuit.

[0082] In some embodiments of the present invention, Figure 5-Figure 8 As shown, Figure 11-Figure 14 As shown, the carrier 10 includes a brush cylinder 11 and a plug-in 12, the brush cylinder 11 is provided with a accommodating cavity 111, the plug-in 12 is fixed to the inner wall of the accommodating cavity 111, a socket 121 is provided in the plug-in 12, and a first electrical connector 33 is fixed to the plug-in 12 and is located in the socket 121, so that the plug-in 12 can be used to protect the first electrical connector 33 to prevent components in the external environment from scratching the first electrical connector 33 and causing damage to the first electrical connector 33.

[0083] In some optional embodiments of the present invention, Figure 5 , Fig.12 As shown, the plug-in 12 and the inner wall of the accommodating cavity 111 are sealed and connected, wherein the connecting shaft 51 is plugged into the socket 121, and there is a risk of water ingress at the end of the electronic brush head 1 facing the brush handle 5. Water can easily enter the interior of the carrier 10 along the inner wall of the plug-in 12 and the accommodating cavity 111, and can easily cause damage to the electrical functional parts 32 inside the carrier 10. Therefore, the plug-in 12 and the inner wall of the accommodating cavity 111 are sealed and connected to prevent water from entering the accommodating cavity 111 from the gap between the plug-in 12 and the inner wall of the accommodating cavity 111, and to prevent the electrical functional parts 32 inside the carrier 10 from being affected.

[0084] In some embodiments, Fig.12As shown, a first sealing ring 41 is provided on the outer peripheral surface of the plug-in 12 to seal the gap between the plug-in 12 and the accommodating cavity 111 to prevent water from entering the interior of the carrier 10 through the gap between the plug-in 12 and the accommodating cavity 111 and causing damage to the electrical functional parts 32 inside the carrier 10.

[0085] In some embodiments, a sealant is provided at the gap between the plug-in 12 and the inner wall of the accommodating cavity 111. The sealant can seal the gap between the plug-in 12 and the accommodating cavity 111 to prevent water from entering the interior of the carrier 10 through the gap between the plug-in 12 and the accommodating cavity 111, thereby preventing the electrical functional components 32 inside the carrier 10 from being damaged.

[0086] In other embodiments of the present invention, Figure 5 As shown, a second sealing ring 42 is provided on the outer peripheral surface of the connecting shaft 51 to seal the gap between the connecting shaft 51 and the accommodating cavity 111, thereby preventing water from entering the interior of the carrier 10 through the gap between the connecting shaft 51 and the accommodating cavity 111, thereby preventing the electrical functional parts 32 inside the carrier 10 from being damaged.

[0087] In some optional embodiments of the present invention, Figure 5 As shown, the electrical component includes a circuit board 31, and the first electrical connector 33 includes a contact point provided on the circuit board 31. The portion of the circuit board 31 provided with the contact point passes through the plug-in 12 to extend into the socket 121. The circuit board 31 and the plug-in 12 are sealed and connected to prevent water from entering the interior of the carrier 10 through the gap between the plug-in 12 and the circuit board 31 when water enters the socket 121, thereby preventing water from damaging the electrical functional parts 32 inside the carrier 10.

[0088] In some embodiments, a sealant is provided in the gap between the circuit board 31 and the plug-in 12. On the one hand, the sealant can fix the circuit board 31 on the plug-in 12 to prevent the circuit board 31 from moving relative to the plug-in 12, thereby ensuring that the contact points on the circuit board 31 can be stably connected to the second electrical connector 52. On the other hand, the sealant can seal the connection between the circuit board 31 and the plug-in 12 to prevent water from entering the interior of the carrier 10 from the gap between the plug-in 12 and the circuit board 31 when water enters the socket 121, thereby preventing water from damaging the electrical components inside the carrier 10.

[0089] In some optional embodiments of the present invention, Fig.12As shown, the first electrical connector 33 is formed as a spring piece 341, and the electronic brush head 1 also includes a connector 13, to which the spring piece 341 is fixed. The connector 13 is used to fix the position of the spring piece 341, and the connector 13 is inserted into the plug-in 12 so that the first electrical connector 33 is located in the socket 121. By fixing the position of the plug-in 12, the position of the first electrical connector 33 can be fixed, so that the spring piece 341 will not move when subjected to a force but can undergo elastic deformation, so that the spring piece 341 can be smoothly electrically connected to the second electrical connector 52.

[0090] In some embodiments, Fig.15 , Fig.16 As shown, the electrical component includes two spring pieces 341, which are arranged in the connector 13 at intervals, and the two spring pieces 341 are kept at a distance to prevent the two spring pieces 341 from contacting each other when subjected to a force, thereby preventing a short circuit. The spring pieces 341 are irregular in shape, and compared with directly setting the spring pieces 341 in the socket 121, it is simpler to first set the spring pieces 341 on the connector 13 and then set the connector 13 in the socket 121, which is convenient for reducing the difficulty of installation.

[0091] In some specific embodiments of the present utility model, a fixed glue layer is provided between the spring piece 341 and the connector 13, which is used to fix the spring piece 341 on the connector 13 on the one hand, and can seal the gap between the spring piece 341 and the connector 13 on the other hand, so as to prevent water in the socket 121 from flowing from the gap between the spring piece 341 and the connector 13 to the electrical functional component 32, thereby preventing the electrical functional component 32 from being damaged.

[0092] In some specific embodiments of the present invention, a sealant is provided between the connector 13 and the plug-in 12 to seal the gap between the connector 13 and the plug-in 12 to prevent water in the socket 121 from flowing from the gap between the connector 13 and the plug-in 12 to the electrical functional component 32, thereby preventing the electrical functional component 32 from being damaged.

[0093] In some optional embodiments of the present invention, Figure 5-Figure 7 , Figure 12-14 As shown, the plug-in 12 is provided with an elastic buckle 122 , which is suitable for buckling with the connecting shaft 51 to achieve plug-in and fixed fit with the connecting shaft 51 , thereby achieving fixed connection between the electronic brush head 1 and the brush handle 5 .

[0094] In some specific embodiments of the present invention, Figure 5 , Fig.12As shown, an avoidance space 123 is formed between the elastic buckle 122 and the inner peripheral wall of the accommodating cavity 111 to reserve space for the elastic deformation of the elastic buckle 122, thereby preventing the inner wall of the accommodating cavity 111 from abutting against the elastic buckle 122 when the elastic buckle 122 is elastically deformed, thereby blocking the cooperation between the plug-in 12 and the connecting shaft 51.

[0095] like Figure 6 and Figure 7 , Fig.13 and Fig.14 As shown, in the axial direction of the connecting shaft 51, a protrusion 511 and a groove 512 are continuously provided on the connecting shaft 51. When the connecting shaft 51 is inserted into the insertion hole 121, the protrusion 511 on the connecting shaft 51 first cooperates with the elastic buckle 122, so that the elastic buckle 122 is elastically deformed in the direction away from the connecting shaft 51. At this time, at least a part of the elastic buckle 122 extends into the avoidance space 123. Subsequently, when the protrusion 511 and the elastic buckle 122 are disengaged, the elastic buckle 122 recovers the deformation and the free end of the elastic buckle 122 extends into the groove 512, so as to realize the buckle fit between the elastic buckle 122 and the connecting shaft 51.

[0096] Among them, a protrusion 511 and a groove 512 are provided to facilitate determining the relative position of the connecting shaft 51 and the socket 121 when the connecting shaft 51 is inserted into the socket 121. At the same time, when one end of the elastic buckle 122 is inserted into the groove, the relative rotation of the connecting shaft 51 and the electronic brush head 1 can be restricted.

[0097] In some optional embodiments of the present invention, Figure 5 , Fig.12 As shown, the first electrical connector 33 is located on a side of the plug 12 away from the entrance of the socket 121, so that the first electrical connector 33 is set at an end away from the entrance of the socket 121. Since there is a risk of water ingress at one end of the entrance of the socket 121, this arrangement is convenient for reducing the possibility of water reaching the first electrical connector 33 and reducing the impact of water on the first electrical connector 33.

[0098] In some embodiments of the utility model, the electrical functional component 32 is a light-emitting component, which can emit a blue light beam with a wavelength of 480-520mm. The blue light can destroy the DNA and RNA structures of bacteria and viruses, thereby achieving a sterilization effect. At the same time, the blue light can also whiten teeth. When the user needs to whiten their teeth, a special whitening agent composed mainly of hydrogen peroxide and silica can be applied to the bristles. At this time, when the blue light is irradiated on the teeth and the whitening agent, an oxidation-reduction reaction will occur on the teeth, thereby achieving the effect of whitening the teeth.

[0099] Among them, the light emitted by the light-emitting part can also be used for lighting, catalyzing the ingredients of toothpaste, reducing inflammation in the oral cavity, promoting blood circulation, etc., and there are no excessive restrictions here.

[0100] In other embodiments, the electrical functional component 32 is a radio frequency electrode, which can emit a radio frequency current, thereby generating charged particles to decompose tooth stains or decompose dental plaque and tartar. Due to the pervasive nature of radio frequency, the radio frequency current can reach blind spots such as tooth gaps and gum lines that are not cleaned by ordinary toothbrushes, thereby meeting the need to clean the blind spots.

[0101] In other embodiments, the electric functional part 32 is an electrolytic electrode, which can ionize water or toothpaste to generate cleaning molecules, and use electricity to adsorb the cleaning molecules to the teeth. The electrolytic electrode can also be used to massage the gums, reduce inflammation, and promote blood circulation. In other embodiments, the electric functional part 32 is a heating wire, which can be used to atomize water or toothpaste to promote the release of cleaning factors in the toothpaste, and can also dry and sterilize the bristles.

[0102] In some other embodiments, the electric function part 32 is a camera. When the user uses the electric toothbrush 1000, the electric function part 32 can be used to photograph the inside of the oral cavity. The user can use the camera to observe the inside of the oral cavity, thereby facilitating the judgment of the health of the oral cavity. In some other embodiments, the electric function part 32 is a thermal imager. The thermal imager is used to form a photoelectric thermal image. When the user uses the electric toothbrush 1000, a photoelectric thermal image of the oral cavity can be formed, thereby facilitating the judgment of the health of the oral cavity.

[0103] The electric toothbrush 1000 according to the embodiment of the present invention is described below. The electric toothbrush 1000 according to the embodiment of the present invention comprises the electronic brush head 1 and the brush handle 5 according to the above embodiment of the present invention, the brush handle 5 is provided with a connecting shaft 51 and a second electrical connector 52 provided on the connecting shaft 51, and the first electrical connector 33 and the second electrical connector 52 form a detachable contact connection.

[0104] According to the electric toothbrush 1000 of the embodiment of the utility model, the first electrical connector 33 and the second electrical connector 52 are electrically connected in contact within the carrier 10, so that the first electrical connector 33 and the second electrical connector 52 are protected by the carrier 10, and the water from the outside is not easy to reach the inside of the jack 121, so as to reduce the probability of water reaching the contact and matching area of ​​the first electrical connector 33 and the second electrical connector 52, reduce the risk of short circuit of the first electrical connector 33 and the second electrical connector 52, and facilitate the stable connection of the first electrical connector 33 and the second electrical connector 52. In some embodiments of the utility model, at least one of the first electrical connector 33 and the second electrical connector 52 is elastic, so that when the first electrical connector 33 and the second electrical connector 52 are in contact and matching, it is convenient to form an elastic extrusion contact between the first electrical connector 33 and the second electrical connector 52, so as to improve the stability of the electrical connection between the first electrical connector 33 and the second electrical connector 52.
