Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, and in particular to a toothbrush. Background Technology

[0002] A vibrating electric toothbrush is a highly efficient oral cleaning tool that combines sonic vibration and rotation technology. It removes plaque and food debris from the tooth surface through high-speed vibration or rotation, helping users clean their teeth and massage their gums more effectively. Vibrating electric toothbrushes typically have two working modes: sonic vibration, which uses high-frequency vibration (usually thousands to tens of thousands of times per minute) to generate fluid dynamics, effectively cleaning the tooth surface and reaching deep into the gaps between teeth; and rotation and oscillation, which uses a rotating brush head or oscillation at a specific angle to enhance the cleaning effect.

[0003] In related technologies, the toothbrush swing angle is above 5° (with the center symmetry line as a reference, 2.5° on the left and right respectively). Because the toothbrush head rotates at a large angle, the range of motion of the cable with pressure sensing function is limited, making it easy to be pulled or even broken. In addition, the limited rotation angle of the brush head will affect the stability and lifespan of the toothbrush. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a toothbrush in which the connecting wire is not easily pulled or broken, thereby improving the stability and lifespan of the toothbrush.

[0005] The toothbrush according to this utility model includes: a bracket, a motor, a circuit board, and a pressure detection component. The bracket is provided with a motor receiving cavity and a clearance cavity. The motor is disposed in the motor receiving cavity. The output shaft passes through the clearance cavity and partially extends out of the bracket. The pressure detection component includes a pressure sensor and a connecting wire. The first end of the connecting wire is electrically connected to the circuit board and the second end is electrically connected to the pressure sensor. The second end of the connecting wire is disposed on the output shaft and located in the clearance cavity. The portion of the connecting wire located in the clearance cavity is bent or bent to form a redundant part.

[0006] Therefore, by setting a motor housing cavity and a clearance cavity on the bracket, the connecting wire is set in the clearance cavity and electrically connected to the circuit board and pressure sensor. Moreover, the part of the connecting wire in the clearance cavity is bent or bent to form a redundant part. This ensures that the redundant part has a certain range of motion, that is, it ensures that when the brush head rotates, the redundant part will not cause the connecting wire to be pulled taut. This can ensure the rotation angle of the brush head, prevent the connecting wire from breaking, reduce the collision of the connecting wire, and reduce the noise generated by the resonance between the connecting wire and the motor. In this way, the stability, service life and comfort of the toothbrush can be improved.

[0007] In some examples of this utility model, the redundant part is curved.

[0008] This design ensures that the curved redundant part experiences more balanced stress during brush head rotation, preventing stress concentration in localized areas and further avoiding localized breakage of the redundant part after prolonged use, thus promoting the longevity of the toothbrush. The curved redundant part also provides extra tension, reducing the contact area between the redundant part and the motor, further reducing resonance between them, and minimizing collisions between the connecting cable and other components, thereby improving the stability of the connecting cable.

[0009] In some examples of this utility model, the bracket is provided with a first fixing part, the connecting line is provided with a second fixing part, the second fixing part is located at the end of the redundant part away from the second end, and the second fixing part is provided on the first fixing part.

[0010] With this configuration, the connecting wire is fixed to the bracket, allowing it to stably transmit current between the motor and the pressure sensor. Furthermore, the second fixing part is positioned away from the second end of the redundant part, with the second end close to the output shaft. This ensures the second fixing part does not interfere with the movement of the redundant part, allowing part of the connecting wire to be fixed to the bracket while another part moves with the brush head's movement, thus preventing the connecting wire from breaking. Additionally, the movable part of the connecting wire is located between the output shaft and the second fixing part, preventing other parts of the connecting wire from being interfered with by the output shaft, thereby improving the toothbrush's structural stability.

[0011] In some examples of this utility model, one of the first fixing part and the second fixing part is provided with a fixing hole and the other is provided with a fixing post, the fixing post passing through the fixing hole; and / or the second fixing part is bonded to the first fixing part.

[0012] With this configuration, the connecting cable is connected to the bracket, and the connecting cable can also be restrained to a certain extent. This ensures that when the brush head moves the redundant part, the other parts of the connecting cable remain stably connected to the bracket, thus guaranteeing the performance of the connecting cable.

[0013] In some examples of this utility model, a positioning groove is provided on the side of the bracket away from the avoidance cavity, and at least a portion of the connecting line between the first end and the second fixing part is provided in the positioning groove.

[0014] With this configuration, the positioning groove limits the connection line, thus preventing it from moving randomly. Moreover, the connection line located in the positioning groove is positioned between the second fixing part and the second end. This section of the connection line does not move within the positioning groove, thereby ensuring the stability of the connection between the connection line and the pressure sensor. It also does not affect the redundant part from moving with the brush head, which is beneficial to the stability of the connection line and ensures the range of motion of the brush head.

[0015] In some examples of this utility model, the bracket includes: a first bracket and a second bracket. The first bracket is provided with a first motor receiving cavity and a first clearance cavity. The second bracket is disposed on the first bracket and is provided with a second motor receiving cavity and a second clearance cavity. The first bracket and the second bracket are fastened together to form part or all of the motor receiving cavity and part or all of the clearance cavity.

[0016] With this configuration, after the first and second brackets are fastened together, a motor can be placed between the first and second motor receiving cavities, thus fixing the motor inside the brackets. The first and second clearance cavities form a partial or complete clearance cavity. After the motor is installed in the motor receiving cavity, the output shaft is placed in the clearance cavity, which provides movement space for the output shaft. This allows the motor's power to be transmitted to the brush head through the output shaft. The fastening method also facilitates the installation of pressure sensors and connecting wires on the output shaft, thus improving efficiency.

[0017] In some examples of this utility model, the toothbrush further includes a pad disposed between the connecting wire and the bracket.

[0018] This design allows the connecting cable to fit more tightly against the pad or bracket, thus facilitating a secure installation between the connecting cable and the bracket. Furthermore, when the brush head swings, the connecting cable will be pulled and tend to move, and the pad can cushion the connecting cable, thereby preventing collisions between the connecting cable and the bracket and further reducing the noise generated by the high-frequency collision of the connecting cable with the bracket.

[0019] In some examples of this utility model, the toothbrush further includes: a display screen, a bracket with a mounting groove, the mounting groove and the circuit board being spaced apart along the length of the bracket, the display screen being disposed in the mounting groove, and the display screen being electrically connected to the circuit board.

[0020] This design allows the toothbrush to form a long, rectangular shape, and also allows the display screen to be placed adjacent to the circuit board. This facilitates electrical connection between the display screen and the circuit board, enabling the display screen to show relevant information and thus helping users to use the toothbrush properly.

[0021] In some examples of this utility model, the inner sidewall of the mounting groove is provided with an elastic buffer, which contacts and engages with the outer peripheral wall of the display screen; and / or the display screen is bonded to the bottom of the mounting groove.

[0022] With this design, the elastic buffer is located between the display screen and the mounting slot. If the toothbrush is accidentally dropped, the elastic buffer provides elasticity and cushioning to the display screen, thereby preventing collisions between the display screen and the bracket and extending the lifespan of both the toothbrush and the display screen.

[0023] In some examples of this utility model, the bracket is provided with a battery receiving cavity, and the toothbrush also includes a battery disposed in the battery receiving cavity; wherein, the bracket is provided with a clamping part on at least one side of the battery receiving cavity, and the clamping part clamps the battery.

[0024] With this configuration, the clamping part can be located on one side or both sides of the battery housing cavity. After the battery is placed in the battery housing cavity, the clamping part holds the battery, thereby making the battery and the bracket more securely fixed in the axial direction.

[0025] In some examples of this utility model, the toothbrush further includes: a handle housing and a light emitter. The handle housing is provided with a light-transmitting part. The light emitter is electrically connected to a circuit board and the emitted light is suitable for transmission outward through the light-transmitting part. The light emitter can control the light emission to make the light-transmitting part gradually fill up.

[0026] With this setup, the circuit board controls the light emitter to turn on or off. When the light emitter is on, the light can be emitted outward through the light-transmitting part, allowing the user to observe the light emitted by the light emitter. The light emitter gradually fills the light-transmitting part with the intensity of the light emitted by itself. That is, as the user brushes their teeth for a longer period of time, the light-transmitting part is gradually filled with light, thus serving as a reminder to the user.

[0027] Compared with the prior art, this utility model adopts a motor receiving cavity and a clearance cavity on the bracket. The connecting wire is set in the clearance cavity and electrically connected to the circuit board and pressure sensor. Moreover, the connecting wire is partially bent or bent in the clearance cavity to form a redundant part. This can ensure that the redundant part has a certain range of motion, that is, ensure that the connecting wire is not pulled taut when the brush head rotates. This can ensure the rotation angle of the brush head, prevent the connecting wire from breaking, reduce the collision of the connecting wire, and reduce the noise generated by the resonance between the connecting wire and the motor. In this way, the stability, service life and comfort of the toothbrush can be improved.

[0041] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0042] The following is for reference. Figures 1-8 Describes a toothbrush 100 according to an embodiment of the present invention. For example, an electric toothbrush.

[0043] like Figures 1-8As shown, the toothbrush 100 according to this utility model includes: a bracket 10, a motor 30, a circuit board 40, and a pressure detection component 50. The bracket 10 is provided with a motor receiving cavity 11 and a clearance cavity 12. The motor 30 is disposed in the motor receiving cavity 11. The output shaft 31 passes through the clearance cavity 12 and partially extends out of the bracket 10. The pressure detection component 50 includes a pressure sensor 51 and a connecting wire 52. The first end of the connecting wire 52 is electrically connected to the circuit board 40 and the second end is electrically connected to the pressure sensor 51. The second end of the connecting wire 52 is disposed in the output shaft 31 and located in the clearance cavity 12. The portion of the connecting wire 52 located in the clearance cavity 12 is bent or bent to form a redundant portion 521.

[0044] It is understood that the bracket 10, motor 30, circuit board 40, and pressure detection component 50 constitute the main structure of toothbrush 100. The bracket 10 is provided with a motor receiving cavity 11 and a clearance cavity 12. The motor 30, circuit board 40, and pressure detection component 50 are disposed within the bracket 10, that is, the motor 30 is disposed within the motor receiving cavity 11 and the clearance cavity 12. The circuit board 40 and the bracket 10 are fixed by protrusions or by adhesive bonding, so that the circuit board 40 can be fixed on the bracket 10. A part of the pressure detection component 50 is disposed in the clearance cavity 12. This allows the bracket 10 to protect the motor 30, circuit board 40, and pressure detection component 50, thereby extending the service life of the motor 30, circuit board 40, and pressure detection component 50, as well as the overall service life of toothbrush 100.

[0045] The motor 30 has an output shaft 31. The clearance cavity 12 provides movement space for the output shaft 31. A part of the output shaft 31 passes through the clearance cavity 12 and extends out of the bracket 10. This allows the output shaft 31 to connect to other components, thus facilitating the transmission of power from the motor 30 to the output shaft 31. The pressure sensor 51 and the connecting line 52 constitute the main structure of the pressure detection assembly 50. The connecting line 52 has two ends, namely a first end and a second end. The first end is electrically connected to the circuit board 40, and the second end is electrically connected to the pressure sensor 51. This allows the circuit board 40 and the pressure sensor 51 to be connected through the connecting line 52. Moreover, the second end is close to the output shaft 31. The clearance cavity 12 can provide an installation position for the second end and provide movement space for the output shaft 31.

[0046] Specifically, the portion of the connecting wire 52 located in the clearance cavity 12 has a bend or redundant portion 521. This portion is bent within the clearance cavity 12. When the toothbrush 100 is in operation, the connecting wire 52 is driven by the rotation of the toothbrush head 100. The connecting wire 52 located in the clearance cavity 12 can unfold, thereby ensuring the range of motion of the connecting wire 52. This ensures that the redundant portion will not cause the connecting wire 52 to be pulled or tightened when the brush head rotates, thereby increasing the rotation angle of the brush head and preventing the connecting wire 52 from being torn off. This extends the service life of the connecting wire 52 and prevents the pressure sensor 51 from being damaged by the swing of the brush head.

[0047] For example, the redundant part 521 is curved. During the rotation of the brush head, the curved redundant part 521 is subjected to more balanced force, preventing stress concentration in a local area of ​​the redundant part 521 and avoiding breakage after prolonged use. This can improve the service life of the toothbrush 100. It can not only reduce the space occupied by the redundant part 521, but also reduce the contact area between the redundant part 521 and the motor 30, further reducing the resonance between the redundant part 521 and the motor 30. In addition, the movement of the redundant part 521 does not affect the movement of other parts of the connecting line 52, thereby expanding the pulling range of the connecting line 52 and reducing the collision between the connecting line 52 and other components, thus improving the stability of the connecting line 52.

[0048] Therefore, by setting a motor receiving cavity 11 and a clearance cavity 12 on the bracket 10, the connecting wire 52 is set in the clearance cavity 12 and electrically connected to the circuit board 40 and the pressure sensor 51. Moreover, the part of the connecting wire 52 in the clearance cavity 12 is bent or bent to form a redundant part 521. This ensures that the redundant part 521 has a certain range of motion, that is, it ensures that when the brush head rotates, the setting of the redundant part 521 will not cause the connecting wire 52 to be pulled taut. This can ensure the rotation angle of the brush head, prevent the connecting wire 52 from breaking, reduce the collision of the connecting wire 52, and reduce the noise generated by the resonance between the connecting wire 52 and the motor 30. In this way, the stability, service life and comfort of the toothbrush 100 can be improved.

[0049] In addition, such as Figure 5 and Figure 6 As shown, the bracket 10 is provided with a first fixing part 13, and the connecting line 52 is provided with a second fixing part 522. The second fixing part 522 is located at the end of the redundant part 521 away from the second end, and the second fixing part 522 is provided on the first fixing part 13.

[0050] It is understood that a first fixing part 13 is provided on the side surface of the bracket 10 facing the relief cavity 12, and a second fixing part 522 is provided on a part of the connecting wire 52 near the relief cavity 12. The first fixing part 13 and the second fixing part 522 are fixedly engaged, so that the connecting wire 52 can be fixed on the bracket 10, thereby allowing the connecting wire 52 to stably transmit the current between the motor 30 and the pressure sensor 51. Moreover, the second fixing part 522 is located in the direction away from the second end of the redundant part 521, and the second end is close to the output shaft 31. This allows the redundant part 521 to be located in the relief cavity 12, and the second fixing part 522 does not affect the movement of the redundant part 521. Thus, a part of the connecting wire 52 can be fixed on the bracket 10, and a part can move with the swing of the brush head, thereby preventing the connecting wire 52 from being torn. Furthermore, the movable part of the connecting wire 52 is between the output shaft 31 and the second fixing part 522, and the other parts of the connecting wire 52 will not be interfered with by the output shaft 31, thereby improving the structural stability of the toothbrush 100.

[0051] Optionally, such as Figure 5 and Figure 6 As shown, one of the first fixing part 13 and the second fixing part 522 is provided with a fixing hole and the other is provided with a fixing post. The fixing post passes through the fixing hole, and the second fixing part 522 is bonded to the first fixing part 13.

[0052] In other words, the first fixing part 13 is a fixing hole, and the second fixing part 522 is a fixing post, or the first fixing part 13 is a fixing post, the second fixing part 522 is a fixing hole, and the fixing post passes through the fixing hole, or the first fixing part 13 and the second fixing part 522 are bonded together. This allows the connecting wire 52 to be connected to the bracket 10 and also provides some restraint to the connecting wire 52. The redundant part 521 is located on the side of the second fixing part 522 near the output shaft 31, so that the movement of the redundant part 521 does not affect the part of the connecting wire 52 that is fixed to the bracket 10, thereby preventing the connecting wire 52 from having an excessive range of movement and affecting the current transmission performance.

[0053] In addition, such as Figure 5 and Figure 6 As shown, a positioning groove 14 is provided on the side of the bracket 10 away from the avoidance cavity 12, and at least a portion of the connecting line 52 located between the first end and the second fixing part 522 is provided in the positioning groove 14.

[0054] It is understandable that the bracket 10 is provided with a positioning groove 14, which is located on the side of the avoidance cavity 12 away from the output shaft 31. Moreover, the positioning groove 14 is opened along the length of the bracket 10. This allows the positioning groove 14 to limit the connection line 52, thereby preventing the connection line 52 from moving randomly. Furthermore, the connection line 52 located in the positioning groove 14 is positioned between the second fixing part 522 and the second end. This section of the connection line 52 does not move within the positioning groove 14, thereby ensuring the stability of the connection between the connection line 52 and the pressure sensor 51. It also does not affect the redundant part 521 from moving with the brush head, which is beneficial to the stability of the connection line 52 and ensures the range of motion of the brush head.

[0055] In addition, such as Figure 4 , Figure 5 and Figure 7 As shown, the bracket 10 includes: a first bracket 15 and a second bracket 16. The first bracket 15 is provided with a first motor receiving cavity and a first clearance cavity. The second bracket 16 is disposed on the first bracket 15 and is provided with a second motor receiving cavity and a second clearance cavity. The first bracket 15 and the second bracket 16 are fastened together to form part or all of the motor receiving cavity 11 and to form part or all of the clearance cavity 12.

[0056] In other words, the first bracket 15 and the second bracket 16 constitute the main structure of the bracket 10. The first bracket 15 and the second bracket 16 are fastened together, which facilitates the installation and disassembly of the bracket 10. It also allows the first bracket 15 and the second bracket 16 to press the connecting line 52, making the connection between the connecting line 52 and the bracket 10 more secure. This facilitates the replacement of the motor 30, circuit board 40, connecting line 52 and pressure sensor 51, thereby improving the service life and resale value of the toothbrush 100. The fastening method also facilitates the installation of the pressure sensor 51 and connecting line 52 on the output shaft 31, thereby improving the assembly efficiency of the toothbrush 100.

[0057] The first bracket 15 is provided with a first motor receiving cavity and a first clearance cavity, and the second bracket 16 is provided with a second motor receiving cavity and a second clearance cavity. The first motor receiving cavity and the second motor receiving cavity correspond to each other, and the first clearance cavity and the second clearance cavity correspond to each other. After the first bracket 15 and the second bracket 16 are fastened together, the motor 30 can be placed between the first motor receiving cavity and the second motor receiving cavity, so that the motor 30 can be fixed in the bracket 10. The first clearance cavity and the second clearance cavity form a partial or complete clearance cavity 12. After the motor 30 is installed in the motor receiving cavity 11, the output shaft 31 is placed in the clearance cavity 12, so that the clearance cavity 12 can provide movement space for the output shaft 31, and thus the power of the motor 30 can be transmitted to the brush head through the output shaft 31.

[0058] In addition, the toothbrush 100 also includes a pad, which is disposed between the connecting wire 52 and the bracket 10. It is understood that the pad, located in the positioning groove 14, not only allows the connecting wire 52 to fit more tightly with the pad or bracket 10, thus making the installation between the connecting wire 52 and the bracket 10 more secure, but also, when the brush head oscillates, the connecting wire 52 is subjected to tension and has a tendency to move. The pad cushions the connecting wire 52, preventing collisions between the connecting wire 52 and the bracket 10, thereby improving the stability between the connecting wire 52 and the bracket 10, and reducing the noise generated by the high-frequency collision of the connecting wire 52 with the bracket 10.

[0059] In addition, such as Figure 7 and Figure 8 As shown, the toothbrush 100 also includes: a display screen 60, a bracket 10 having a mounting groove 17, the mounting groove 17 and the circuit board 40 being spaced apart along the length of the bracket 10, the display screen 60 being disposed in the mounting groove 17, and the display screen 60 being electrically connected to the circuit board 40.

[0060] In other words, the bracket 10 is provided with a mounting slot 17, which provides installation space for the display screen 60. Furthermore, the mounting slot 17 and the circuit board 40 are spaced apart along the length of the bracket 10, allowing the toothbrush 100 to form a long, rectangular whole. This also allows the display screen 60 and the circuit board 40 to be arranged adjacent to each other, facilitating electrical connection between them and enabling the display screen 60 to show relevant information. This, in turn, allows the user to use the toothbrush 100 appropriately. For example, the display screen 60 can show the remaining battery level or vibration level, allowing the user to use it according to their actual needs, thus enhancing the practicality of the toothbrush 100.

[0061] In addition, such as Figure 7 and Figure 8 As shown, an elastic buffer 18 is provided on the inner side wall of the mounting groove 17. The elastic buffer 18 contacts and engages with the outer peripheral wall of the display screen 60, and the display screen 60 is bonded to the bottom of the mounting groove 17.

[0062] Understandably, an elastic buffer 18 is provided on the mounting slot 17. One side of the elastic buffer 18 is attached to the inner wall of the mounting slot 17, and the other side is attached to the outer periphery of the display screen 60. This allows the elastic buffer 18 to be positioned between the display screen 60 and the mounting slot 17. If the toothbrush 100 is accidentally dropped, the elastic buffer 18 provides elasticity and cushioning to the display screen 60, thereby preventing collisions between the display screen 60 and the bracket 10, and thus extending the service life of both the toothbrush 100 and the display screen 60. For example, the elastic buffer 18 can be made of thermoplastic polyurethane soft rubber, ensuring cushioning performance without excessively increasing the overall weight of the toothbrush 100.

[0063] In addition, such as Figures 3-5 and Figure 7 As shown, the bracket 10 is provided with a battery receiving cavity 19, and the toothbrush 100 also includes a battery 70, which is disposed in the battery receiving cavity 19; wherein, the bracket 10 is provided with a clamping part 20 on at least one side of the battery receiving cavity 19, and the clamping part 20 clamps the battery 70.

[0064] In other words, the bracket 10 is provided with a battery receiving cavity 19, which is in a semi-open state. The battery receiving cavity 19 can limit the battery 70, thereby facilitating the installation of the battery 70 on the bracket 10. The bracket 10 can also protect the battery 70, thereby extending the service life of the battery 70. The bracket 10 is provided with a clamping part 20, which can be on one side or both sides of the battery receiving cavity 19. After the battery 70 is placed in the battery receiving cavity 19, the clamping part 20 clamps the battery 70, thereby making the battery 70 and the bracket 10 more firmly fixed in the axial direction.

[0065] In addition, such as Figure 2 and Figure 4 As shown, a guide portion 21 is provided on the bracket 10, and a guide groove 81 is provided on the inner side of the handle housing 80. The guide portion 21 protrudes relative to the surface of the bracket 10, and the guide portion 21 and the guide groove 81 are guided and engaged, so that the handle housing 80 can be placed on the bracket 10, and thus it is convenient for the user to operate the handle housing 80 to use the toothbrush 100.

[0066] In addition, such as Figure 1 and Figure 6 As shown, the toothbrush 100 also includes: a handle housing 80 and a light emitter 90. The handle housing 80 is provided with a light-transmitting part 82. The light emitter 90 is electrically connected to the circuit board 40 and the light emitted is suitable for transmission outward through the light-transmitting part 82. The light emitter 90 can control the light emission so that the light-transmitting part 82 gradually fills up.

[0067] It is understandable that a light-transmitting part 82 is provided on the handle shell 80, and the light emitter 90 is electrically connected to the circuit board 40, so that the circuit board 40 can control the light emitter 90 to turn on or off. When the light emitter 90 is turned on, the light can be emitted outward through the light-transmitting part 82, allowing the user to observe the light emitted by the light emitter 90. The light emitter 90 and the light-transmitting part 82 are set to different colors. The intensity of the light emitted by the light emitter 90 gradually fills the light-transmitting part 82. That is, as the user's brushing time increases, the light-transmitting part 82 is gradually filled with light, thus serving as a reminder to the user. For example, the light emitter 90 is made into a long strip, and the light emitted by the light emitter 90 can gradually fill the strip. If the brushing time is 2 minutes, as the user uses the toothbrush 100, the length of the light in the light-transmitting part 82 gradually increases. When the 2 minutes are up, the light from the light emitter 90 fills the light-transmitting part 82, thus allowing the user to brush their teeth for a more scientific and reasonable time, thereby enhancing the technological sophistication of the toothbrush 100.
