Description

Technical Field

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

[0002] Superficial needling therapy, also known as push needling therapy, is a type of acupuncture. Its therapeutic principle involves applying pressure to acupoints through small-amplitude vibrations at a specific frequency. Traditional Chinese medicine uses a spiral-shaped needle placed on the acupoint, and then the practitioner slides their hand along the spiral to vibrate the needle and apply pressure. This traditional treatment relies entirely on the doctor's experience, resulting in inconsistent and unreliable therapeutic effects. Therefore, a superficial needling device has been developed that uses machine vibration to apply pressure.

[0003] The vibration structure of superficial acupuncture devices initially employed traditional linear reciprocating mechanisms such as cams and linear motors. These mechanisms suffer from low vibration precision, making it difficult to achieve fine, small-amplitude vibrations. To address this issue, our company has introduced a superficial acupuncture vibration device that utilizes a flat plate vibrator or bone conduction vibrator to drive a vibration head and other vibration transmission components, as disclosed in Chinese patent application number 202410756998.1. While this device can achieve small-amplitude vibrations, the vibration head, pressed and constantly in contact with the vibration transmission components by the limiting component, is tightly bound and locked. This results in very low flexibility and freedom of movement for the vibration head. A significant portion of the vibration energy transmitted from the flat plate vibrator or bone conduction vibrator to the vibration head is absorbed by the limiting component, making it difficult for the vibration energy to accurately reach the human body for superficial acupuncture treatment. Utility Model Content

[0004] The purpose of this invention is to provide a shallow needle oscillator.

[0005] The technical solution to achieve the purpose of this utility model is: a shallow needle vibrator, comprising a housing, a vibration conductor, and a vibration head. The housing has a through hole, the vibration conductor is fixedly installed inside the housing, and a vibration head mounting space is provided inside the housing. The vibration head mounting space is located between the through hole and the vibration conductor. The vibration head includes a connected body and a head. The width of the body is greater than the diameter of the through hole, and the width of the head is not greater than the diameter of the through hole. The body is located within the vibration head mounting space, and the head passes through the through hole and extends out of the housing. The thickness of the body is less than the height of the vibration head mounting space.

[0006] Furthermore, the difference between the height of the vibrating head mounting space and the thickness of the main body is 0.3mm to 0.5mm. The thickness of the main body is less than the height of the vibrating head mounting space, and there is a gap between the vibrating head mounting space and the main body. The size of this gap can be, but is not limited to, any value between 0.3mm and 0.5mm, but preferably 0.4mm.

[0007] Furthermore, the width of the main body is smaller than the width of the vibrating head mounting space, and the width of the head is smaller than the diameter of the through hole. With this configuration, the head of the vibrating head is less restricted by the vibrating head mounting space and the through hole, allowing for greater flexibility and left-right swinging space. This swinging space serves two purposes: firstly, during use, if the head is slightly misaligned with an acupoint, simply swinging the head to align it with the acupoint is sufficient, without needing to adjust the entire position of the shallow needle vibrator, making alignment easier; secondly, during operation, especially when wearing a device with the shallow needle vibrator, when the head of the vibrating head contacts an acupoint, the lateral force on the head can be converted into a swaying motion, preventing lateral scratches and improving the user experience.

[0008] Furthermore, the bottom of the main body is provided with a groove, and the top of the vibration transmission component is provided with a boss, which extends into the groove. The boss and the groove form a limiting position, and during vibration, under the action of this limiting position, the vibration transmission component and the vibration head can be aligned, and the vibration head is not easily misaligned.

[0009] Furthermore, the head is cylindrical, and the through hole is a cylindrical through hole. After the cylindrical head passes through the cylindrical through hole, there is no axial limitation between the two, allowing the vibrating head to have a higher degree of freedom of vibration and more accurate transmission of vibration energy.

[0010] Furthermore, the top surface of the head is spherical. The spherical top surface of the head is rounded and without sharp edges, preventing scratches to the human body during use. Simultaneously, the spherical top surface provides a larger contact area when in contact with the human body, resulting in lower pressure under the same force, and a more subtle and gentler "blunt" feeling of force.

[0011] Furthermore, the head is located in the middle of the main body, and the cross-section of the vibrating head is T-shaped. The T-shaped vibrating head has better symmetry, and the vibrating head operates more stably when the vibration transmission component drives the vibrating head to vibrate.

[0012] Furthermore, the housing includes a housing body and an assembly. The housing body has a mounting hole with a diameter not less than the diameter of the through hole. The assembly is located at the mounting hole and is assembled and connected to the housing body. The through hole is located on the assembly. The space between the vibration conductor and the assembly forms the vibration head mounting space. The housing can be a single-piece structure or assembled from the housing body and the assembly. Compared to the former, the latter, where the housing body and the assembly are assembled, offers greater flexibility in their design, allowing for the use of different materials. For example, the housing body can be a rigid structure, while the assembly can be a flexible structure.

[0013] Furthermore, the fitting is made of silicone. Silicone fittings are highly flexible, and the space between them and the vibration transmission component forms the installation space for the vibration head. When the main body is positioned within this installation space, during use, the silicone fitting can buffer the force exerted by the vibration head, making the vibration gentler and providing a better human experience, without causing stinging sensations, while also reducing vibration noise. On the other hand, the deformation of the silicone fitting provides a larger travel space for the vibration head, allowing for a larger vibration amplitude and a wider vibration range. Within this wider vibration range, the vibration head can generate more vibration modes, conveniently meeting the needs of superficial needle treatment under various vibration modes.

[0014] Furthermore, the assembly is located within the housing body. The assembly can be located either outside or inside the housing body. Compared to the former, when the assembly is located inside the housing body, the installation of the assembly is more secure and reliable under the constraint of the housing body.

[0015] Furthermore, the fitting includes a cap body and a brim extending outward from the bottom periphery of the cap body. The cap body extends into and fits into the mounting hole, and the through hole is located on the cap body. After the cap body extends into and fits into the mounting hole, on the one hand, the cap body can fill the mounting hole, making the overall shell more flat and aesthetically pleasing; on the other hand, it can reduce the thickness of the shell, making the required length of the head extending out of the shell shorter. This makes installation more convenient, and the shorter head also results in more stable force transmission when vibrations act on the human body, reducing swaying.

[0016] Furthermore, the top surface of the cap is flush with the surface of the housing body. This design makes the overall housing smoother and more aesthetically pleasing.

[0017] Furthermore, the main body is located within the cap body. In this configuration, the main body within the cap body is, on the one hand, limited by the cap body for easy installation; on the other hand, the cap body, without the shell's obstruction, has a stronger deformation capacity. During vibration of the vibrating head, the force of the main body acts on the more deformable cap body, resulting in better vibration buffering. The vibration of the vibrating head is gentler, providing a better human experience, without causing stinging sensations, and also reducing vibration noise. Moreover, with the deformation of the more deformable cap body, the main body can vibrate with a larger amplitude, satisfying a wider vibration range.

[0018] Furthermore, a limiting seat is provided within the housing body, and the periphery of the accessory is clamped between the housing body and the limiting seat. When the accessory includes a cap body and a brim extending outward from the bottom periphery of the cap body, the periphery of the brim is clamped between the housing body and the limiting seat. The accessory and the housing body can be fixed by adhesive, bolts, or clamping. For ease of assembly and disassembly and to avoid damaging the accessory, clamping is preferred.

[0019] Furthermore, the housing body includes an upper housing and a lower housing that interlock. This arrangement facilitates the assembly and disassembly of the housing body. The upper housing and the lower housing can be secured together with bolts.

[0020] Furthermore, the vibration transmission element is a flat plate vibrator or a bone conduction vibrator. The vibration transmission element can be a traditional mechanical vibration mechanism, such as a cam-type vibration mechanism or a linear motor, or it can be a flat plate vibrator or a bone conduction vibrator. Compared to mechanical vibration mechanisms, flat plate vibrators or bone conduction vibrators are not only smaller and easier to install, but also have higher vibration precision, capable of achieving even minute vibrations, resulting in better therapeutic effects for shallow needle therapy with small amplitude vibrations.

[0021] This utility model relates to a shallow needle vibrator. By making the thickness of the main body less than the height of the vibrating head mounting space, the main body in the vibrating head mounting space is not compressed or locked, and the main body has a vibration space within the vibrating head mounting space. The presence of this vibration space provides two advantages. First, it grants the vibrating head greater freedom of movement. With fewer restrictions, except for the vibration stroke limit, the vibration energy transmitted to the vibrating head by the vibration conductor is largely absorbed before reaching the vibration stroke limit, preventing it from being transferred to other components. This absorption of most of the vibration energy by the vibration conductor allows for more accurate vibration carrying that energy. In other words, after the vibration conductor produces the vibration for shallow acupuncture treatment, the vibrating head can accurately reproduce that vibration, thus acting on the body and improving the therapeutic effect. Second, the vibration space also provides a larger stroke range for the vibrating head, allowing for greater vibration amplitude and a wider vibration range. This wider range enables the vibrating head to form more vibration modes, facilitating shallow acupuncture treatment under various vibration patterns.

[0022] Furthermore, in this invention's shallow needle vibrator, with its separate structure of the vibrating head and the vibration transmission component, the installation of the vibrating head is unaffected by the installation accuracy of the vibration transmission component, facilitating installation. While the vibration transmission component drives the vibrating head to vibrate, during the process of acting on the human body, the vibration of the vibration transmission component does not directly act on the human body, but is transmitted through the vibrating head. The vibrating head both transmits the vibration of the vibration transmission component and isolates the vibration force on the vibration transmission component. In particular, the main body reserves vibration space within the installation space of the vibrating head, allowing the vibrating head greater degrees of freedom. The rigid connection between the vibration transmission component and the vibrating head is not static. During the process of the vibration transmission component driving the vibrating head to strike, if the vibrating head is still moving forward due to inertia while the vibration transmission component has retracted, the rigid connection between the separately configured vibration transmission component and the vibrating head weakens, reducing force transmission and resulting in a gentler final force from the vibrating head. Compared to the direct vibration and harsh force of a one-piece structure, the vibrating head of this invention, which is separately set from the vibration transmission component and has a greater degree of vibration freedom, delivers a gentler force to the human body, without causing stinging sensation, making it more acceptable to the human body and providing a better experience and comfort.

[0024] Figure 2This is a three-dimensional cross-sectional view of the shallow needle oscillator of this utility model;

[0025] Figure 3 This is a cross-sectional structural schematic diagram of the shallow needle oscillator of this utility model. Detailed Implementation

[0026] The preferred embodiment of the shallow needle oscillator of this utility model will be described in detail below with reference to the accompanying drawings:

[0027] like Figures 1 to 3 As shown, a shallow needle oscillator includes a housing 1, a vibration conductor 2, and a vibration head 3. The housing 1 has a through hole 10. The vibration conductor 2 is fixedly installed inside the housing 1. A vibration head mounting space 20 is provided inside the housing 1, located between the through hole 10 and the vibration conductor 2. The vibration head 3 includes a connected body 31 and a head 32. The width D1 of the body 31 is greater than the diameter R1 of the through hole 10, and the width D2 of the head 32 is not greater than the diameter R1 of the through hole 10. The body 31 is located within the vibration head mounting space 20, and the head 32 passes through the through hole 10 and extends out of the housing 1. Along the vibration direction of the vibration head 3, the thickness H1 of the body 31 is less than the height H2 of the vibration head mounting space 20.

[0028] This utility model relates to a shallow needle vibrator. The housing 1 is used to encapsulate the vibration transmission element 2 or the vibration head 3. The vibration transmission element 2 vibrates, and the vibrating vibration element 2 then transmits power to the vibration head 3, causing the vibration head 3 to vibrate as well. In the vibration head 3, the width D1 of the main body 31 is greater than the diameter R1 of the through hole 10, which is used to limit the main body 31 within the vibration head mounting space 20; the width D2 of the head 32 is not greater than the diameter R1 of the through hole 10, and the head 32 passes through the through hole 10 to extend out and contact the human body, thus exerting a force on the human body. The thickness H1 of the main body 31 is less than the height H2 of the vibration head mounting space 20, so the main body 31 is not compressed or locked, and the main body 31 has vibration space within the vibration head mounting space 20.

[0029] In use, the head 32 of the vibrating head 3 is placed against the acupoint on the human body. Under the pressure of the human body, the main body 31 of the vibrating head 3 is in contact with the vibration transmission element 2. Then, the vibration transmission element 2 is activated, driving the vibrating head 3 to vibrate. The vibrating head 32 acts on the human body to achieve superficial acupuncture treatment.

[0030] This utility model of a shallow needle vibrator ensures that the thickness H1 of the main body 31 is less than the height H2 of the vibrating head mounting space 20, so that the main body 31 of the vibrating head mounting space 20 is not compressed or locked, and the main body 31 has a vibration space within the vibrating head mounting space 20. The presence of this vibration space provides two advantages. First, it grants the vibrating head 3 greater freedom of vibration. With fewer restrictions, except for the vibration stroke limit, the vibration transmission element 2 drives the vibrating head 3 to vibrate. When transmitting vibration energy to the vibrating head 3, this energy is almost entirely absorbed by the vibrating head 3 before reaching the vibration stroke limit, without being transferred to other components. Having absorbed most of the vibration energy from the vibration transmission element 2, the vibrating head 3 can more accurately reproduce the vibration carrying that energy. In other words, after the vibration transmission element 2 produces the vibration for shallow acupuncture treatment, the vibrating head 3 can more accurately reproduce the vibration produced by the vibration transmission element 2, thus acting on the human body and achieving better shallow acupuncture treatment results. Second, the presence of this vibration space also provides the vibrating head 3 with a larger stroke space, allowing for a larger vibration amplitude and a wider vibration range. Within this wider vibration range, the vibrating head 3 can form more vibration modes, conveniently meeting the needs of shallow acupuncture treatment under various vibration modes.

[0031] Furthermore, in the shallow needle vibrator of this invention, with the vibrating head 3 and the vibrating transmission component 2 separately configured, the installation of the vibrating head 3 is not affected by the installation accuracy of the vibrating transmission component 2, facilitating installation. While the vibrating transmission component 2 drives the vibrating head 3 to vibrate, during the process of acting on the human body, the vibration of the vibrating transmission component 2 does not directly act on the human body, but is transmitted through the vibrating head 3. The vibrating head 3 both transmits the vibration of the vibrating transmission component 2 and isolates the vibration force on the vibrating transmission component 2. In particular, the main body 31 reserves vibration space within the vibrating head installation space 20. With greater vibration freedom, the rigid connection between the vibrating transmission component 2 and the vibrating head 3 is not constant. During the process of the vibrating transmission component 2 driving the vibrating head 3 to strike, when the vibrating head 3 is inertially forward while the vibrating transmission component 2 has retracted, the rigid connection between the separately configured vibrating transmission component 2 and the vibrating head 3 weakens, reducing the force transmission, and the final force exerted by the vibrating head 3 is more gentle. Compared to the direct vibration and harsh force of a one-piece structure, the vibration head 3, which is separately set from the vibration transmission component 2 in this invention, delivers a gentler force to the human body, without causing stinging sensation, making it more acceptable to the human body and providing a better experience and comfort.

[0032] In this invention, the shallow needle vibrator preferably has a height H2 of the vibrating head mounting space 20 and a thickness H1 of the main body 31 of 0.3mm to 0.5mm. The thickness H1 of the main body 31 is less than the height H2 of the vibrating head mounting space 20, and there is a gap between the vibrating head mounting space 20 and the main body 31. The size of this gap can be, but is not limited to, any value between 0.3mm and 0.5mm, but preferably 0.4mm.

[0033] In this invention, the width D1 of the main body 31 is smaller than the width D3 of the vibrating head mounting space 20, and the width D2 of the head 32 is smaller than the diameter R1 of the through hole 10. With this configuration, the head 32 of the vibrating head 3 is less restricted by the horizontal direction of the vibrating head mounting space 20 and the through hole 10, allowing for greater flexibility and left-right swinging space. This swinging space allows for several advantages. First, during use, if the head 32 is slightly misaligned with an acupoint, simply swinging the head 32 to align it with the acupoint is sufficient, without needing to adjust the entire position of the shallow needle vibrator, making alignment easier. Second, during operation, especially when wearing a device with the shallow needle vibrator, when the head 32 of the vibrating head 3 touches an acupoint, the lateral force on the head 32 can be converted into a sway, preventing the head 32 from scratching the body and improving the user experience.

[0034] In this invention, a shallow needle vibrator is preferably provided with a groove 311 at the bottom of the main body 31 and a boss 21 at the top of the vibration transmission member 2, the boss 21 extending into the groove 311. The boss 21 and the groove 311 form a limiting position, and during vibration, under the action of this limiting position, the vibration transmission member 2 and the vibration head 3 can be aligned, and the vibration head 3 is not easily misaligned.

[0035] In this invention, the shallow needle vibrator preferably has a cylindrical head 32 and a cylindrical through hole 10. After the cylindrical head 32 passes through the cylindrical through hole, there is no axial limitation between them, allowing the vibrating head 3 to have greater freedom of movement and more accurate energy transmission.

[0036] In this invention, the shallow needle vibrator preferably has a spherical top surface on its head 32. The spherical top surface of the head 32 is rounded and without sharp edges, preventing scratches to the human body during use. Furthermore, the spherical top surface provides a larger contact area with the human body, resulting in lower pressure under the same force and a more subtle, gentler sensation of force. The top radius of the head 32 can be, but is not limited to, 2.5 mm.

[0037] In this invention, the shallow needle vibrator preferably has its head 32 located in the middle of the main body 31, and the cross-section of the vibrating head 3 is T-shaped. The T-shaped vibrating head 3 has better symmetry, and the vibrating head 3 operates more stably when it is driven to vibrate by the vibration transmission member 2.

[0038] In this invention, a shallow needle vibrator is preferably constructed in which the housing 1 comprises a housing body 11 and an assembly 12. The housing body 11 has a mounting hole 110, the diameter R2 of which is not less than the diameter R1 of the through hole 10. The assembly 12 is located at the mounting hole 110 and is assembled and connected to the housing body 11. The through hole 10 is located on the assembly 12. The space between the vibration conductor 2 and the assembly 12 forms the vibration head mounting space 20. The housing 1 can be a single integral structure or assembled from the housing body 11 and the assembly 12. Compared to the former, the latter, where the housing body 11 and the assembly 12 are assembled, allows for greater flexibility in their design, enabling the use of different materials. For example, the housing body 11 can be a rigid structure, while the assembly 12 can be a flexible structure.

[0039] Preferably, the fitting 12 of this shallow needle vibrator is made of silicone. The silicone fitting 12 has high flexibility, and the space between it and the vibration conductor 2 forms the vibration head mounting space 20. After the main body 31 is located within the vibration head mounting space 20, during use, on the one hand, the silicone fitting 12 can buffer the force of the vibration of the vibration head 3, making the vibration of the vibration head 3 gentler, providing a better human experience, and reducing the stinging sensation; on the other hand, the deformation of the silicone fitting 12 also provides a larger stroke space for the vibration of the vibration head 3, allowing the vibration head 3 to perform a larger vibration amplitude and a wider vibration range. Within this wider vibration range, the vibration head 3 can form more vibration modes, conveniently meeting the needs of shallow needle treatment under different vibration modes.

[0040] In this invention, the shallow needle vibrator preferably has the assembly 12 located inside the housing body 11. The assembly 12 can be located outside or inside the housing body 11. Compared to the former, when the assembly 12 is located inside the housing body 11, the installation of the assembly 12 is more secure and reliable under the constraint of the housing body 11.

[0041] In this utility model of a shallow needle vibrator, preferably, the assembly 12 includes a cap 121 and a brim 122 extending outward from the bottom periphery of the cap 121. The cap 121 extends into and fits into the mounting hole 110, and the through hole 10 is located on the cap 121. After the cap 121 extends into and fits into the mounting hole 110, on the one hand, the cap 121 can fill the mounting hole 110, making the overall shell 1 flatter and more aesthetically pleasing; on the other hand, it can reduce the thickness of the shell 1, making the required length of the head 32 extending out of the shell 1 shorter. This makes the installation more convenient, and the shorter head 32 also makes the force transmission more stable when vibrating on the human body, reducing sway.

[0042] In this invention, the top surface of the cap 121 is flush with the surface of the housing body 11. This arrangement makes the overall housing 1 more flat and aesthetically pleasing.

[0043] In this invention, the shallow needle vibrator preferably has its main body 31 located within the cap 121. With this configuration, the main body 31, located within the cap 121, is limited by the cap 121, facilitating installation. Furthermore, without the shell 1 providing support, the cap 121 has a stronger deformation capacity. During vibration of the vibrating head 3, the force exerted by the main body 31 on the more deformable cap 121 results in better vibration buffering by the cap 121, leading to a gentler vibration from the vibrating head 3, improved comfort, and reduced vibration noise without causing stinging. Moreover, the deformation of the cap 121 allows for a larger vibration amplitude and a wider vibration range.

[0044] In this invention, a shallow needle vibrator is preferably provided with a limiting seat 13 inside the housing body 11, and the periphery of the fitting 12 is clamped between the housing body 11 and the limiting seat 13. When the fitting 12 includes a cap 121 and a brim 122 extending outward from the bottom periphery of the cap 121, the periphery of the brim 122 is clamped between the housing body 11 and the limiting seat 13. The fitting 12 and the housing body 11 can be fixed by adhesive, bolts, or clamping. For ease of disassembly and assembly, and to avoid damaging the fitting 12, clamping is preferred.

[0045] In this invention, the shallow needle vibrator preferably includes an upper housing 111 and a lower housing 112 that interlock. This arrangement facilitates the assembly and disassembly of the housing 11. The upper housing 111 and the lower housing 112 can be fixed together by bolts.

[0046] Preferably, the vibration transmission element 2 of this invention is a flat plate vibrator or a bone conduction vibrator. The vibration transmission element 2 can be a traditional mechanical vibration mechanism, such as a cam-type vibration mechanism or a linear motor, or it can be a flat plate vibrator or a bone conduction vibrator. Compared to mechanical vibration mechanisms, flat plate vibrators or bone conduction vibrators are not only smaller and easier to install, but also have higher vibration precision, capable of achieving even minute vibrations, resulting in better therapeutic effects for shallow acupuncture treatment with small amplitude vibrations. Flat plate vibrators and bone conduction vibrators are existing structures, and will not be elaborated upon further in this invention.

[0047] This utility model of shallow needle oscillator can be used directly, or it can be used with a strap, or it can be installed inside an eyeglass frame.

[0048] For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model, and all such deductions or substitutions should be considered to fall within the protection scope of this utility model.
