Conductive structure of sonic vibration motor, electric toothbrush, and brush head power supply structure thereof

Abstract

The present application belongs to the field of electric toothbrushes. Provided are a conductive structure of a sonic vibration motor, an electric toothbrush and a brush head power supply structure thereof. The conductive structure comprises a sonic vibration motor body, a hollow conductive motor shaft and a conductive assembly. The motor shaft of the sonic vibration motor is implemented as a hollow conductive structure, the inside thereof serving as a wiring channel; the conductive assembly passes through the body along the central axis of the motor shaft and is externally connected, so as to form a first conducting circuit; and the motor shaft itself serves as a second conducting circuit by means of the conductivity property thereof. Two ends of the two conducting circuits are respectively connected to an electric element and a power supply to form a circuit. Thus, by means of fully utilizing the features of the structure of the sonic vibration motor itself, the present application simply needs to configure the motor shaft to be hollow, and does not need significant structural modification on the motor. Since a first power connection output end and a second power connection output end are both integrated on the motor shaft itself, although the motor vibrates reciprocatingly at a high frequency, the power connection efficiency is not affected, and extra wiring layout is not needed. In addition, the two output ends allow externally-assembling installation, thereby achieving advantages in both safety and convenience.

Description

Conductive structure of sonic motor, electric toothbrush and brush head power supply structure thereof Technical Field

[0001] The present invention relates to the field of electric toothbrushes, and in particular provides a conductive structure of a sonic motor, an electric toothbrush and a power supply structure for a brush head thereof. Background Art

[0002] With the development of intelligent society, more and more electrical appliances are entering the public's lives. As living standards improve, more and more consumers are paying attention to oral health issues. For example, electric toothbrushes, which use a sonic motor as a driving force, generate high-frequency reciprocating vibrations of a certain amplitude to drive the brush head to oscillate at high frequencies, thereby achieving tooth cleaning and greatly improving daily life. Currently, there are few electric toothbrushes on the market with illuminated brush heads and other functions. Most are conventional electric toothbrushes. A few blue-light or red-light electric toothbrushes often require significant modifications to the motor output shaft to complete the power supply wiring, making the structure complex. Alternatively, the addition of parts or changes in motor type can significantly reduce motion transmission efficiency, thereby reducing the amplitude and frequency of the brush head's oscillation. For example, Chinese patent CN 215019476 U describes a sonic electric toothbrush structure with sterilization and blue-light whitening. This structure uses a wireless charging coil for power supply, which inevitably increases the number of parts, resulting in unsatisfactory brush head oscillation. Alternatively, to accommodate the conductive components, the brush head and motor output shaft increase in size, reducing the user experience. To address this issue, the present invention has been developed.

[0060] in: DETAILED DESCRIPTION

[0061] The preferred embodiments described below are for illustrative purposes only, and those skilled in the art may readily conceive of other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0062] Unless the context clearly requires otherwise, throughout the specification and claims, words such as "include," "comprising," and similar expressions should be interpreted as inclusive rather than exclusive or exhaustive; that is, as meaning "including but not limited to." The word "and / or" is used to simplify expressions. For example, "A and / or B" includes both "A and B" and "A or B," where "A or B" is interpreted as either "A" or "B"; and "A and B" is interpreted as both "A" and "B" being selected.

[0063] The sonic motor or sonic motor of an electric toothbrush is a motor that, when powered alternately in forward and reverse directions at a certain frequency, causes the motor output shaft to swing back and forth at this frequency, thereby truly achieving the "brushing teeth" action. This vibration principle is based on the attraction and repulsion of the stator and rotor inside the motor. There is no mechanical friction inside the motor, and it has strong stability, high output power, and can generate high-frequency vibrations, achieving a similar "sound wave" effect. Therefore, it is accepted and widely used by people in this field. The above is necessary for understanding the premise of this application.

[0064] Example 1:

[0065] Please refer to Figures 1 to 5 in conjunction with Figures 6 and 7. Figures 1 and 3 do not show the mounting bracket in order to illustrate the conductive path, but this is fully shown in Figures 2, 6, and 7. The present invention primarily provides a conductive structure for an acoustic wave motor, comprising an acoustic wave motor body 1, a hollow conductive shaft 2, and a conductive assembly. One end of the hollow conductive shaft 2 is inserted into the acoustic wave motor body 1 and is output by the acoustic wave motor body 1 to produce high-frequency reciprocating vibrations of a certain amplitude. A section of the hollow conductive shaft 2 extends outside the acoustic wave motor body 1 to form an output section 20. The output section 20 has a first power output terminal 201, and the hollow conductive shaft 2 also has a first power input terminal 221. The conductive assembly includes at least a first conductive member 31, a second conductive member 33, and an insulating mounting base 32. The first conductive member 31 is mounted on the output section 20 via the insulating mounting base 32 to form a second power output terminal. One end of the second conductive member 33 is connected to the first conductive member 31, and the other end passes through the hollow conductive shaft 2 and extends outward to form a second power input terminal 331.

[0066] As shown in Figures 6 and 7 , the mounting bracket 4 can be sleeved onto the hollow conductive shaft 2 and at least circumferentially fixed relative to the hollow conductive shaft 2. The mounting bracket 4 has a first assembly port 41 for assembling and connecting electrical components at the first power output terminal 201, and a second assembly port 42 for assembling and connecting electrical components at the second power output terminal. This embodiment implements the motor shaft of the acoustic wave motor as a hollow conductive structure, with its interior serving as a wiring channel. The conductive component extends from the shaft's central axis through the body to form a first conductive path, while the motor shaft itself, utilizing its conductive properties, serves as a second conductive path. Both ends connect to the electrical components and the power supply, respectively, forming pathways. This fully utilizes the inherent structural characteristics of the acoustic wave motor, requiring only a hollow shaft configuration without requiring major structural modifications to the motor. Furthermore, both the first power output terminal 201 and the second power output terminal are integrated into the motor shaft itself. Despite the high-frequency reciprocating vibration of the motor, this does not affect power connection efficiency, eliminating the need for additional wiring layout. Furthermore, both output terminals can be externally assembled, offering unparalleled advantages in safety and convenience.

[0067] The above is necessary for implementing the basis of this embodiment, and is further described in detail below with reference to the accompanying drawings:

[0068] In this embodiment, the sonic motor body 1 is implemented as the structure of the sonic motor except for the motor shaft, which includes a shell, a stator, a rotor and bearing parts in the openings at both ends of the shell. This is the principle structure of the sonic motor and sonic motor. This embodiment does not make technical improvements to the principle structure, so it will not be elaborated.

[0069] As a preferred embodiment of this embodiment, please refer to Figures 1 and 2. The hollow conductive shaft 2 also includes a shaft wire 22. One end of the shaft wire 22 is connected to the hollow conductive shaft 2 and the first power output terminal 201 for electrical conduction, and the other end is implemented as the first power input terminal 221. In practice, the other end of the shaft wire 22 is connected to the control motherboard 8 or battery 9 of the power supply component (as shown in Figure 12), and the electrical components are powered by connecting to the first power output terminal 201. Preferably, the shaft wire 22 is wrapped with insulating plastic to prevent leakage. During the wiring process, the maximum amplitude of a reciprocating swing of the hollow conductive shaft 2 should be considered, and the reserved space length should be sufficient to prevent it from being broken.

[0070] Furthermore, the shaft conductor 22 can be routed internally or externally within the hollow conductive shaft 2. For external routing, as shown in FIG1 , a connection hole 21 is formed in the sidewall of the output section 20 of the hollow conductive shaft 2. One end of the shaft conductor 22 is concealedly connected to the hollow conductive shaft 2 through the connection hole 21, while the other end extends outside the hollow conductive shaft 2 to the power supply element.

[0071] Alternatively, during internal wiring, a connection hole 21 is formed on the side wall of the output section 20 of the hollow conductive shaft 2, and one end of the shaft wire 22 is hidden and connected to the hollow conductive shaft 2 through the connection hole 21, and the other end extends and is routed inside the hollow conductive shaft 2.

[0072] Furthermore, referring to FIG3 , this embodiment further includes a first conductive sheet 23, which is mounted on the acoustic wave motor body 1 and in contact with the hollow conductive shaft 2. One end of the shaft conductor 22 is connected to the first conductive sheet 23 to facilitate electrical conduction between the shaft conductor 22 and the hollow conductive shaft 2. Preferably, the first conductive sheet 23 has a through-hole in the middle, in which a flexible contact portion 231 is provided. The hollow conductive shaft 2 is passed through the through-hole, and the flexible contact portion 231 is pressed against the hollow conductive shaft 2 for contact and electrical conduction. The first conductive sheet 23 can be mounted on the acoustic wave motor body 1. Preferably, there are two flexible contact portions 231, located on both sides of the hollow conductive shaft 2, in contact with the hollow conductive shaft 2. The flexible contact portions 231 can be implemented as metal conductors or stranded metal wires.

[0073] It should be noted that in this embodiment, the hollow conductive shaft 2 serves as a conductive bridge for electrically connecting the power supply and the power consumption components. The connection between the power supply and the hollow conductive shaft 2 is not limited to any specific method. While the aforementioned connection method involves contact with the first conductive sheet 23 and the shaft wire 22, other methods are also possible and should not be construed as limiting. The first and second power input terminals 221 and 331 can be connected to the power supply directly via positive and negative wires, or via contact connections such as electrode sheets or metal springs, depending on the specific implementation.

[0074] Furthermore, the first conductive member 31 is a first electrode, and the second conductive member 33 is a second wire; the first electrode is mounted at the end of the output section 20 through the insulating mounting seat 32, the second wire is passed through the hollow conductive shaft 2 and connected to the first electrode, the second power input end 331 is defined as the end of the second wire away from the first electrode, and the second power output end is defined as the first electrode.

[0075] Furthermore, in conjunction with Figures 6, 7 and 8, in order to facilitate docking with electrical components, this embodiment also includes an electrical connection assembly, which includes a first electrical connection assembly 72 and a second electrical connection assembly 71. The first electrical connection assembly 72 is detachably assembled to the first assembly port 41 and contacts the first electrical output terminal 201, and the second electrical connection assembly 71 is detachably assembled to the second assembly port 42 and contacts the second electrical output terminal; the first electrical connection assembly 72 and the second electrical connection assembly 71 are connected to the positive and negative poles of the electrical components through wires for power supply.

[0076] As a preferred embodiment of this embodiment, the first power connection member 71 is implemented as a conductive spring. The bottom of the conductive spring has an elastic deformation portion 711. The mounting bracket 4 is provided with a guide groove 40 along the insertion direction. The first assembly opening 41 is located within the guide groove 40. The conductive spring compresses the elastic deformation portion 711 and is inserted along the guide groove 40 into the first assembly opening 41. The elastic deformation portion 711 extends into the first assembly opening 41 and contacts the first power output terminal 201 for electrical conduction.

[0077] Furthermore, the second electrical connection member 72 is a conductive probe that contacts the first electrode for electrical conduction. The electrical component only needs to be connected to the conductive probe and the conductive spring via a wire for electrical conduction. Preferably, the conductive spring is implemented as a deformable spring, with the deformable portion corresponding to the elastic deformation portion 711.

[0078] The power supply element in this embodiment can be implemented as a control mainboard 8, and the power-consuming element can be implemented as a lighting effect function component, a sensor or a camera component, etc. provided in the electric toothbrush head 5.

[0079] Please refer to FIG2 . The conductive paths of this embodiment are as follows:

[0080] First, the power supply element is connected to the positive and negative poles through the first power input terminal 221 and the second power input terminal 331, and then the first power input terminal 221 is connected to the connection hole 21 on the output section 20 through the machine shaft wire 22. At the same time, the first power output terminal 201 on the machine shaft output section 20 is conductive to form a first circuit; the second power input terminal 331 is connected to the first conductive member 31 (implemented as the first electrode, also defined as the second power output terminal) through the second conductive member 33 (implemented as the second wire) to form a second circuit, and the insulating properties of the insulating mounting base 32 and the second wire prevent a short circuit from being formed between the two circuits; finally, the positive and negative poles of the electrical element are connected to the first power output terminal 201 and the first electrode.

[0081] The beneficial effects of the above technical solutions can come from one or a combination of the following:

[0082] The present application implements the motor shaft of the sonic wave motor as a hollow conductive structure, the interior of which serves as a wiring channel, and the conductive component is passed from the shaft along the axis through the body to form a first conductive circuit, and the motor shaft itself uses its conductive properties as a second conductive circuit; the two ends are respectively connected to the electrical components and the power supply to form a path; the structural characteristics of the sonic wave motor itself are fully utilized, and it is only necessary to set the shaft hollow without making major structural changes to the motor; and the first power output terminal 201 and the second power output terminal are integrated in the motor shaft itself. Although the motor vibrates reciprocatingly at high frequency, it does not affect the power connection efficiency, and no additional wiring layout is required. The two output terminals are stably contacted internally through the mounting bracket 4 and assembled externally, which has incomparable advantages in safety and convenience.

[0083] While completing the external output linkage through the mounting bracket 4, the structure of the mounting bracket 4 can also be attached. When the electrical components are installed on the mounting bracket 4, they can be assembled with the assembly port on the mounting bracket 4 at the same time, thereby realizing the power connection of the two output ends.

[0084] The hollow conductive shaft 2 can be used for all internal wiring, or a line can be led out to the outside using the shaft wire 22. It has strong adaptability and wide application. It is particularly suitable for the conductive structure where the power supply is on one side of the sonic motor body 1 and the electrical components are on the other side. It has strong integration and high space utilization, reduces the difficulty of wiring, and improves durability.

[0085] The two power output terminals are connected separately through the power connection assembly, making assembly very convenient and providing clear wiring. The power supply circuit is integrated into the acoustic motor, and the circuit for the power component is integrated into the power component structure. The two only need to be assembled and connected. The mounting bracket 4 further stabilizes the contact structure between the two, greatly improving reliability compared to the purely wired connection available on the market.

[0088] Furthermore, the conductive structure of the acoustic wave motor includes an acoustic wave motor body 1, a hollow conductive shaft 2, and a conductive assembly. One end of the hollow conductive shaft 2 extends through the interior of the acoustic wave motor body 1 and is output by the acoustic wave motor body 1 as a high-frequency reciprocating vibration of a certain amplitude. A section of the hollow conductive shaft 2 extends outside the acoustic wave motor body 1 to form an output section 20. The output section 20 has a first power output terminal 201. The hollow conductive shaft 2 also has a first power input terminal 221.

[0102] The beneficial effects of the present invention are:

[0103] The present application implements the motor shaft of the sonic wave motor as a hollow conductive structure, the interior of which serves as a wiring channel, and the conductive component is passed from the shaft along the axis through the body to form a first conductive circuit, and the motor shaft itself uses its conductive properties as a second conductive circuit; the two ends are respectively connected to the electrical components and the power supply to form a path; the structural characteristics of the sonic wave motor itself are fully utilized, and it is only necessary to set the shaft hollow without making major structural changes to the motor; and the first power output terminal 201 and the second power output terminal are integrated in the motor shaft itself. Although the motor vibrates reciprocatingly at high frequency, it does not affect the power connection efficiency, and no additional wiring layout is required. The two output terminals are stably contacted internally through the mounting bracket 4 and assembled externally, which has incomparable advantages in safety and convenience.

[0104] While completing the external output linkage through the mounting bracket 4, the structure of the mounting bracket 4 can also be attached. When the electrical components are installed on the mounting bracket 4, they can be assembled with the assembly port on the mounting bracket 4 at the same time, thereby realizing the power connection of the two output ends.

It is particularly suitable for the conductive structure where the power supply is on one side of the sonic motor body 1 and the electrical components are on the other side. It has strong integration and high space utilization, reduces the difficulty of wiring, and improves durability.

[0106] The two power output terminals are assembled and connected separately through the power connection components, which makes assembly very convenient and the lines are clear. The lines of the power supply structure are integrated on the sonic motor, and the lines of the electrical components are integrated in the electrical component structure. The two only need to be assembled and installed to achieve contact; and the mounting bracket 4 further stabilizes the contact structure of the two, which greatly improves the reliability compared to the pure wire connection on the market.

[0107] The brush handle 6 of the electric toothbrush is plugged into the mounting bracket 4, allowing the sonic motor body 1 to electromagnetically drive the hollow conductive shaft 2. This, in turn, drives the brush handle 6 through the mounting bracket 4 to rotate back and forth at a high frequency, ultimately driving the brush head 5 to oscillate at a high frequency. The two electrical connections are implemented as a conductive probe and a conductive spring. The conductive probe plugs into the first electrode, while the conductive spring is assembled with the mounting bracket 4 via a guide slot 40. The structural stability of the mounting bracket 4 ensures electrical contact, ensuring high assembly and stability.
