[0039] 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.

[0040] The electronic brush head 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 8 As shown, the electronic brush head 1 according to the embodiment of the present utility model includes a carrier 10 , bristles, a circuit board 31 , electrical functional parts and a conductive part 33 .

[0042] The electronic brush head 1 is applied to the electric toothbrush 1000, and the carrier 10 has a accommodating cavity 11. The carrier 10 includes a first end 101 and a second end 102. The first end 101 is used to connect with the brush handle 5 of the electric toothbrush 1000, and the bristles are connected to the second end 102. The carrier 10 is used to realize the connection between the brush handle 5 and the electronic brush head 1. The bristles and the brush handle 5 are arranged at both ends of the carrier 10 so that the bristles and the brush handle 5 are arranged at intervals, so that when the user holds the brush handle 5, it is convenient for the user to use the bristles to clean the teeth.

[0043] The circuit board 31 is arranged in the accommodating cavity 11, the conductive part 33 is arranged at the first end 101, the conductive part 33 is electrically connected to the circuit board 31, the electrical functional part is electrically connected to the circuit board 31, and the brush handle 5 supplies power to the circuit board 31 through the conductive part 33. The circuit board 31 can supply power to the electrical functional part and transmit information to the electrical functional part so that the electrical functional part can take effect at the corresponding position of the bristles, thereby meeting the user's multi-functional requirements for the electric toothbrush 1000.

[0044] Among them, the electrical functional component is arranged in the accommodating cavity 11 and / or at least partially exposed on the surface of the carrier 10. When the electrical functional component is working, it can produce an effect at the position corresponding to the bristles, so that when the user uses the bristles to clean teeth, the electrical functional component can provide the user with additional effects through the bristles.

[0045] Specifically, the electrical functional parts in the related technology are arranged at the electronic brush head, and there is a certain distance between the electrical functional parts and the brush handle. When the electronic brush head has multiple electrical functional parts, if each electrical functional part is electrically connected to the brush handle one by one, the electrical connection is more complicated due to the long distance between the electrical functional parts and the brush handle. Moreover, when using wires to realize the electrical connection between the electrical functional parts and the brush handle, due to the long length and large number of wires, too much space in the electric toothbrush will be occupied.

[0046] In this solution, a circuit board 31 is set up, and the circuit board 31 is electrically connected to the brush handle 5 through a conductive member 33, so that the electrical functional parts are electrically connected to the circuit board 31. Since the circuit board 31 and the electrical functional parts are both arranged in the electronic brush head 1, the distance between the electrical functional parts and the circuit board 31 is short, so that the electrical functional parts are electrically connected to the circuit board 31, and the connection method is relatively simple, which makes it easy to integrate multiple electrical functional parts on the circuit board 31, and to simplify the electrical connection structure for electrically connecting multiple electrical functional parts, thereby reducing the space occupied by the electrical connection structure for connecting the electrical functional parts in the electric toothbrush 1000.

[0047] According to the electronic brush head 1 of the embodiment of the utility model, a circuit board 31 is arranged in the accommodating cavity 11, so that the circuit board 31 is electrically connected to the electrical functional parts, which facilitates the simplification of the electrical connection structure for electrically connecting multiple electrical functional parts and reduces the space occupied by the electrical connection structure for connecting the electrical functional parts in the electric toothbrush 1000.

[0048] The electronic brush head 1 according to a specific embodiment of the present utility model is described below with reference to the accompanying drawings.

[0049] In some specific embodiments of the present invention, Figure 1-Figure 8 As shown, the electronic brush head 1 according to the embodiment of the present utility model includes a carrier 10 , bristles, a circuit board 31 , electrical functional parts and a conductive part 33 .

[0050] In some embodiments of the utility model, there are multiple electrical functional parts, and the electronic brush head 1 also includes a power connection part. The circuit board 31 is electrically connected to the electrical functional parts through the power connection part. The number of power connections is greater than the number of conductive parts 33, so as to simplify the electrical connection structure for electrically connecting multiple electrical functional parts.

[0051] Specifically, in the prior art, the electrical functional parts are electrically connected to the brush handle of the electric toothbrush through connecting wires or connecting plates. In the present application, a circuit board 31 is arranged in the accommodating cavity 11, so that the electrical functional parts are electrically connected to the circuit board 31 through the connecting parts. The circuit board 31 is connected to the brush handle 5 through a conductive member 33. The number of connecting wires or connecting plates is the same as the number of connecting parts, but the length of the connecting wires or connecting plates is much larger than the length of the connecting parts. In this way, even if the conductive member 33 is added in the present application compared with the prior art, the number of conductive members 33 is less than the number of connecting wires or connecting plates. Therefore, the present application can simplify the electrical connection structure for electrically connecting multiple electrical functional parts and reduce the space occupied by the electrical connection structure for connecting electrical functional parts in the electric toothbrush 1000.

[0052] The electrical connection structure may be a wire, an electrical contact or a welding point.

[0053] In some embodiments, each electrical functional component is electrically connected to the circuit board 31 through a corresponding electrical connection. In order to form a loop between the electrical functional component and the circuit board 31, each electrical functional component needs to be electrically connected to the circuit board 31 by at least two electrical connections. In order to realize the loop between the circuit board 31 and the brush handle 5 in the electric toothbrush 1000, at least two conductive parts 33 need to be electrically connected between the circuit board 31 and the brush handle 5. Therefore, when the electronic brush head 1 includes multiple electrical functional components, the number of electrical connections is greater than the number of conductive parts 33. Compared with the prior art, even if the present application adds conductive parts 33, the number of conductive parts 33 is less than the number of power connection wires or power connection plates. Therefore, the present application can simplify the power connections and reduce the space occupied by the power connections in the electric toothbrush 1000.

[0054] In some embodiments, the electrical connection member may be a wire, an electrical contact, or a solder joint, that is, the electrical functional component and the circuit board 31 may be electrically connected via a wire, an electrical contact, or a solder joint.

[0055] When there are multiple electrical functional components, the electrical connection method between each electrical functional component and the circuit board 31 can be the same or different, and no excessive restrictions are made here.

[0056] In some examples, the electrical functional parts in the prior art are connected to the brush handle via a wire. Since the distance between the electrical functional parts and the brush handle is far, the length of the wire connecting the electrical functional parts and the brush handle is long, and the wire used to connect the electrical functional parts and the brush handle occupies a large space in the electric toothbrush. The electrical functional parts and the circuit board 31 of this embodiment are electrically connected via electrical contacts and solder joints, thereby facilitating a reduction in the number of wires in the electric toothbrush 1000 and reducing the space occupied by the wires in the electric toothbrush 1000.

[0057] In some embodiments of the present invention, the conductive member 33 includes a power supply part 331 , and the handle 5 in the electric toothbrush 1000 is electrically connected to the circuit board 31 via the power supply part 331 , so as to supply power to the circuit board 31 via the power supply part 331 .

[0058] The power supply part 331 includes a positive power supply part and a negative power supply part, so that a loop is formed between the circuit board 31 and the brush handle 5 by using the power supply part 331, so that the brush handle 5 can smoothly supply power to the circuit board 31.

[0059] In some optional embodiments of the present invention, the conductive member 33 also includes an information transmission unit. The signal received in the electric toothbrush 1000 is transmitted to the circuit board 31 through the information transmission unit. After receiving the information, the circuit board 31 can transmit the corresponding information to the electrical functional component, so that the corresponding electrical functional component can make a corresponding response, thereby achieving a corresponding effect.

[0060] In some embodiments, the information transmission part is a signal transmission line. The electrical signal received at the brush handle 5 can be transmitted to the circuit board 31 through the signal transmission line, and then transmitted to the electrical functional parts through the circuit board 31, so that the corresponding electrical functional parts can respond accordingly according to the signal, thereby achieving the corresponding effect.

[0061] In other embodiments, the information transmission part is a communication module, which is suitable for signal transmission with the brush handle 5 to receive and / or output signals. The signal received at the brush handle 5 can be transmitted to the circuit board 31 through the communication module, and then transmitted to the electrical functional parts through the circuit board 31, so that the electrical functional parts can respond accordingly according to the signal, thereby achieving the corresponding effect.

[0062] In some embodiments of the present invention, there are multiple electrical functional components, and the multiple electrical functional components are connected to the circuit board 31, so that the multiple electrical functional components can be integrated together by using the circuit board 31. In this way, when installing the multiple electrical functional components on the carrier 10, there is no need to install the electrical functional components on the carrier 10 one by one. The multiple electrical functional components and the circuit board 31 can be installed on the carrier 10 together, which is convenient to simplify the installation steps and reduce the difficulty of installation.

[0063] In some embodiments of the present invention, there are multiple electrical functional components, the types of the multiple electrical functional components are the same, and the multiple electrical functional components can achieve the same function. By setting up multiple electrical functional components, the effect of the electrical functional components can be improved.

[0064] In some embodiments, the electrical functional component 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.

[0065] 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.

[0066] In other embodiments, the electrical functional component 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.

[0067] In other embodiments, the electrical functional component is 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 electrolytic electrode can also be used to massage the gums, reduce inflammation, and promote blood circulation.

[0068] In other embodiments, the electrical functional component 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.

[0069] In other embodiments, the electrical functional component is a camera. When the user uses the electric toothbrush 1000, the electrical functional component 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 judgment of the health of the oral cavity.

[0070] In some other embodiments, the electrical functional component is a thermal imager, which 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.

[0071] In other embodiments of the present invention, the electronic brush head 1 includes various types of electrical functional parts, so that the electronic brush head 1 has different functions to meet the multi-functional needs of users.

[0072] In some embodiments, the plurality of electrical functional components include a light emitting component and a camera. The light emitting component is used to illuminate the inside of the oral cavity and provide a light source for the camera so that the camera can take clear pictures of the inside of the oral cavity, thereby facilitating the judgment of the health condition of the oral cavity.

[0073] In some embodiments, the plurality of electrical functional components may include two or more of a light emitting component, a radio frequency electrode, an electrolysis electrode, a heating wire, a camera, and a thermal imager, without further limitation.

[0074] In some embodiments of the present invention, Figure 4 As shown, the conductive member 33 is formed as an elastic member, one end of the conductive member 33 is electrically connected to the circuit board 31 and the other end is suitable for elastic contact with the brush handle 5 of the electric toothbrush 1000, and the brush handle 5 is detachably electrically connected to the conductive member 33, so that the conductive member 33 can be used to realize the electrical connection between the circuit board 31 and the brush handle 5, so that the brush handle 5 can conduct electricity to the circuit board 31 through the conductive member 33.

[0075] The conductive member 33 is removably matched with the brush handle 5 in elastic contact, so that the electronic brush head 1 can be easily removed from the brush handle 5 , so that the user can repair and clean the electronic brush head 1 .

[0076] In some optional embodiments of the present invention, there are multiple conductive members 33, and a clamping space is defined between the multiple conductive members 33. The circuit board 31 is clamped in the clamping space and electrically connected to each conductive member 33 to achieve a stable electrical connection between the conductive member 33 and the circuit board 31.

[0077] In some embodiments, the conductive member 33 includes a positive power supply part and a negative power supply part, and a clamping space is formed between the positive power supply part and the negative power supply part. The positive power supply part and the negative power supply part are located on both sides of the thickness direction of the circuit board 31 and the circuit board 31 is clamped in the clamping space. On the one hand, the end of the circuit board 31 can be fixed, and on the other hand, a stable electrical connection between the conductive member 33 and the circuit board 31 can be achieved.

[0078] In some embodiments of the present invention, Figure 5 As shown, the carrier 10 includes a brush tube 103 and a hair transplanting plate 104, the bristles are connected to the hair transplanting plate 104, the brush tube 103 has a accommodating cavity 11, and the hair transplanting plate 104 is separately arranged from the brush tube 103, so that after the bristles are implanted on the hair transplanting plate 104, the hair transplanting plate 104 can be installed on the brush tube 103, which is convenient for reducing the difficulty of hair transplanting.

[0079] The brush barrel 103 is relatively large in size and it is difficult to fix the brush barrel 103 . By implanting the bristles on the bristle implanting plate 104 and then fixing the bristle implanting plate 104 on the brush barrel, the difficulty of bristle implanting can be reduced.

[0080] In some embodiments, the outer peripheral surface of the brush tube 103 is an arc surface, and the hair transplanting plate 104 has at least one plane. When the bristles need to be implanted on the carrier 10, it is more difficult to fix the brush tube 103, but it is relatively simple to fix the hair transplanting plate 104, which makes it convenient to implant the bristles on the hair transplanting plate 104, thereby reducing the difficulty of hair transplanting.

[0081] In some optional embodiments of the present invention, at least one electrical functional component is arranged opposite to the hair implantation plate 104 to act on the bristles, so that the electrical functional component can function in the oral cavity, thereby meeting the needs of the user.

[0082] In some embodiments, when the electrical functional component is working, the electrical functional component can produce an effect at the bristles or around the bristles, for example, it can generate a light beam at the bristles or around the bristles, and the light beam is used to clean the bacteria on the bristles, thereby sterilizing the oral cavity and whitening the teeth.

[0083] Specifically, when the electric toothbrush 1000 is used, the bristles are in contact with the teeth, and the electrical functional parts are arranged opposite to the hair implantation plate 104, so that the electrical functional parts can act on the teeth, thereby meeting the user's needs for whitening, observation, deep cleaning, etc. of the teeth.

[0084] In some specific embodiments of the present invention, Figure 4 , Figure 8 As shown, the end of the brush barrel 103 is provided with an installation cavity 12 for placing the bristle implanting plate 104, and the installation cavity 12 is connected with the accommodating cavity 11 through a through channel 13. The circuit board 31 is an elastic member suitable for extending into the accommodating cavity 11 through the through channel 13, so that the circuit board 31 can be installed in the accommodating cavity 11, so that the electrical functional parts electrically connected to the circuit board 31 are arranged opposite to the bristles.

[0085] like Figure 8 As shown, the installation cavity 12 has a side opening. When the circuit board 31 is installed in the accommodating cavity 11, one end of the circuit board 31 enters the installation cavity 12 through the side opening, and this end of the circuit board 31 passes through the through channel 13 to enter the accommodating cavity 11. When the circuit board 31 is installed in the accommodating cavity 11, the circuit board 31 can undergo elastic deformation, thereby reducing the difficulty of installation so that the circuit board 31 can be smoothly installed in the accommodating cavity 11.

[0086] In some embodiments, Figure 5 , Figure 8 As shown, a slot 14 is provided in the accommodating cavity 11, and the circuit board 31 is inserted into the slot 14 to fix the position of the circuit board 31, thereby preventing the circuit board 31 from shaking when the electric toothbrush 1000 is moved or used, thereby preventing the circuit board 31 from affecting the electrical connection with the conductive part 33 and the electrical functional parts.

[0087] In some examples, such as Figure 5 , Figure 7 As shown, the inner wall of the accommodating cavity 11 is provided with a protruding protrusion 15, and the slot 14 is provided in the protruding portion 15. When the circuit board 31 is inserted into the slot 14, the protruding portion 15 can limit the movement of the circuit board 31, thereby fixing the circuit board 31 in the accommodating cavity 11.

[0088] like Figure 7 As shown, in this embodiment, the protrusion 15 includes a first protrusion 151 and a second protrusion 152, and the first protrusion 151 and the second protrusion 152 are spaced apart along the thickness direction of the circuit board 31 to limit the movement of the circuit board 31 and thereby fix the circuit board 31 in the accommodating cavity 11.

[0089] In some examples, the thickness direction of the circuit board 31 extends in the front-to-back direction, the length direction of the circuit board 31 extends in the up-down direction, the upper end of the circuit board 31 is abutted against the wall of the accommodating cavity 11, the lower end of the circuit board 31 is electrically connected to the conductive member 33, the left and right ends of the circuit board 31 are both abutted against the wall of the accommodating cavity 11, the first protrusion 151 located on the front side of the circuit board 31 is used to limit the forward movement of the circuit board 31, and the second protrusion 152 located on the rear side of the circuit board 31 is used to limit the backward movement of the circuit board 31, so as to fully fix the position of the circuit board 31 from all directions of the circuit board 31, and then confine the circuit board 31 in the accommodating cavity 11, so as to avoid the circuit board 31 shaking when moving or using the electric toothbrush 1000, thereby affecting the electrical connection between the circuit board 31 and the conductive member 33 and the electrical functional parts.

[0090] In some embodiments, Figure 5 , Figure 8 As shown, the accommodating cavity 11 includes a first part 111, a second part 112 and a third part 113. The first part 111 is used to place electrical functional parts. In the height direction of the electronic brush head 1, the second part 112 is located between the first part 111 and the third part 113. The slot 14 is located in the third part 113. The second part 112 is arranged opposite to the slot 14. When the circuit board 31 extends into the accommodating cavity 11 through the through channel 13, a part of the circuit board 31 extends into the slot 14 through the second part 112, and the other part remains in the first part 111 and the second part 112, so as to set the circuit board 31 in the accommodating cavity 11.

[0091] Among them, in the cross-section perpendicular to the height direction, the maximum cross-sectional area of ​​the second part 112 is respectively smaller than the minimum cross-sectional area of ​​the first part 111 and the minimum cross-sectional area of ​​the third part 113. When the circuit board 31 extends into the slot 14 through the second part 112, the second part 112 can guide the movement of the circuit board 31 on the one hand, and limit the distance that the circuit board 31 extends into the slot 14 on the other hand.

[0092] Specifically, the circuit board 31 includes a first plate portion, a second plate portion and a third plate portion. The first plate portion is located in the first part 111, the second plate portion is located in the second part 112, and the third plate portion is located in the third part 113. When the circuit board 31 is installed in the accommodating cavity 11, when the third plate portion passes through the second part 112, since the cross-sectional area of ​​the third plate portion is smaller than that of the second part 112, the third plate portion can smoothly pass through the second part 112 to reach the third part 113. At the same time, the second part 112 can guide the movement of the third part 113, so that the third part 113 can smoothly reach the slot 14.

[0093] In some embodiments, at least part of the cross-sectional area of ​​the first plate portion is larger than the cross-sectional area of ​​the second portion 112, so that when the third plate portion moves to the third portion 113, the first plate portion cannot pass through the second portion 112 to reach the third portion 113, thereby enabling the first plate portion to be confined within the first portion 111 to limit the position of the circuit board 31 and prevent the circuit board 31 from escaping from the accommodating cavity 11.

[0094] In some embodiments, Figure 8 As shown, the first part 111, the second part 112 and the slot 14 are arranged in the up-down direction (it should be understood here that the above direction limitation is only for the convenience of describing the accompanying drawings and will not limit the actual setting position and direction of the electronic brush head 1), the second part 112 connects the first part 111 and the slot 14, the first part 111 and the through channel 13 are arranged opposite to each other in the front-to-back direction, the circuit board 31 extends into the first part 111 from the through channel 13, moves along the wall surface of the first part 111 to the second part 112, passes through the second part 112 and extends into the slot 14, and then the circuit board 31 is set in the accommodating cavity 11.

[0095] In some embodiments of the present invention, Figure 8 As shown, the bottom wall of the mounting cavity 12 is provided with a supporting surface 16 surrounding the through channel 13, and the hair-implanting plate 104 is supported on the supporting surface 16 to limit the position of the hair-implanting plate 104, so that at least one electrical functional component is arranged opposite to the hair-implanting plate 104, so that the electrical functional component can act on the bristles, and thus the electrical functional component can play a role when the user uses the electric toothbrush 1000 to clean teeth.

[0096] In some optional embodiments of the present invention, the hair-implanting plate 104 and the supporting surface 16 are sealed to seal the gap between the hair-implanting plate 104 and the supporting surface 16, so as to prevent water from entering the accommodating cavity 11 through the gap between the hair-implanting plate 104 and the supporting surface 16 when the electric toothbrush 1000 is used, thereby preventing the circuit board 31 from being damaged.

[0097] In some specific embodiments of the utility model, the support surface 16 is provided with a sealing groove 161 arranged around the through channel 13, and a sealing layer adhered to the hair implanting board 104 is provided in the sealing groove 161. On the one hand, the sealing strip is used to fix the hair implanting board 104 on the support surface 16, and on the other hand, it can seal the gap between the support surface 16 and the hair implanting board 104 to prevent water from entering the accommodating cavity 11 through the gap between the hair implanting board 104 and the support surface 16, thereby avoiding damage to the circuit board 31.

[0098] Among them, by setting the sealing groove 161, a part of the sealing strip is set in the sealing groove 161, which is convenient for increasing the connection area between the sealing strip and the support surface 16, and then using the sealing strip to stably fix the hair implantation plate 104 and the support surface 16 together.

[0099] The electric toothbrush 1000 according to the embodiment of the present invention is described below.

[0100] The handle 5 is provided with an insertion portion 51, which is inserted into the first end 101 to drive the electronic brush head 1 to vibrate, thereby driving the bristles at the second end 102 of the electronic brush head 1 to vibrate, so that the bristles can vibrate to clean the teeth. The handle 5 also includes a power supply 52, which is used to supply power to the circuit board 31. Since the circuit board 31 is electrically connected to the electrical functional part, the circuit board 31 can supply power to the electrical functional part so that the electrical functional part can function.

[0101] According to the electric toothbrush 1000 of the embodiment of the utility model, by utilizing the electronic brush head 1 according to the above-mentioned embodiment of the utility model, by arranging the circuit board 31 in the accommodating cavity 11, the circuit board 31 is electrically connected to the electrical functional parts, so as to simplify the electrical connection structure for electrically connecting multiple electrical functional parts and reduce the space occupied by the electrical connection structure for connecting the electrical functional parts in the electric toothbrush 1000.
