Tear film instability, increased tear osmotic pressure, ocular surface inflammation and damage, and neurological abnormalities are the main pathogenesis of dry eye and are also common causes of dry eye.
[0003] A vibration therapy device is one of the commonly used devices for treating dry eyes. It places a massage head on the nasal bone area of the human face so that the massage head vibrates to stimulate the lacrimal gland nerves to produce tears.
[0004] However, the existing vibration therapeutic apparatus has poor vibration effect and controllability and produces relatively high noise. Utility Model Content
[0005] The embodiment of the utility model provides a vibration therapeutic device, which has better vibration effect and controllability and low noise.
[0006] The utility model embodiment provides a vibration therapy device, comprising: a shell; a vibration head, including an excitation end, the excitation end extending out of the shell; a vibration transmitter connected to the vibration head; an amplitude limiting member, one end of which is connected to the shell, and the other end is connected to the vibration transmitter, for supporting the vibration transmitter and limiting the suspended vibration of the vibration transmitter along the axial direction of the amplitude limiting member within a preset amplitude range; a vibration driving member, the vibration driving member is connected to the vibration transmitter, and the vibration driving member is used to drive the vibration transmitter to vibrate along the axial direction of the vibration head, so as to drive the excitation end to apply vibration excitation along the axial direction of the vibration head.
[0007] The vibration therapy device of the utility model directly drives the vibration transmitting body and the vibration head connected as one body to vibrate through the vibration driving member, without relying on resonance to transmit vibration, and has a better vibration effect. The amplitude limiting member limits the vibration of the vibration transmitting body in the axial direction of the amplitude limiting member, so that the vibration body mainly vibrates in the axial direction of the vibration head, and then drives the excitation end of the vibration head to apply vibration excitation in the axial direction of the vibration head to stimulate the lacrimal gland nerve to produce tears. Not only the vibration controllability is enhanced, but also the vibration reduction effect is good and the noise is small.
[0008] In a feasible solution, the vibration therapy device includes a plurality of amplitude limiting members, and the plurality of amplitude limiting members are distributed at intervals between the vibration transmission body and the housing. The plurality of amplitude limiting members can further improve the vibration reduction effect and reduce noise.

By arranging the columnar main body portion of the amplitude limiting member so that its rotation center axis is co-directional with the axial direction of the amplitude limiting member, when the vibration driving member is working, the columnar main body portion of the amplitude limiting member utilizes deformation along the direction of its own rotation center axis to achieve vibration reduction in the axial direction of the amplitude limiting member, which has a simple structure and a good vibration reduction effect.
[0010] In a feasible solution, a through hole is provided in the amplitude limiting member and penetrates the amplitude limiting member in the axial direction thereof. The design of the through hole can further improve the deformation flexibility of the amplitude limiting member along the direction of its own rotation center axis, and achieve a better shock absorption effect.

The vibration driving member is arranged between the floating bracket and the pressure bridge of the vibration transmission body, and the vibration generated by the vibration driving member can be directly transmitted to the vibration transmission body, with high vibration transmission efficiency, controllable vibration and better effect.
[0012] In a feasible solution, the pressure bridge includes a strip-shaped pressing part and a first arm and a second arm respectively connected to the two ends of the pressing part, the first arm is connected to one end of the vibration head, and the other end of the vibration head away from the first arm is the free excitation end; the first arm and the second arm are respectively connected to the floating bracket. The pressing part of the pressure bridge and the first arm and the second arm at the two ends form a U-shaped structure, which can stably connect the vibration drive member and the vibration transmission body.
[0013] In a feasible solution, the floating bracket is provided with a groove, and the vibration driving member is fixed between the groove and the pressing part. The groove combined with the U-shaped structure of the pressure bridge can form a receiving cavity to accommodate the vibration driving member, so as to more stably install the vibration driving member and prevent the vibration driving member from loosening.
[0014] In a feasible solution, at least one weight-reducing groove is provided on the floating bracket, which can reduce the weight of the floating bracket and reduce the noise caused by the vibration of the floating bracket.
[0015] In a feasible solution, the vibration driving member includes a motor and an eccentric block connected to the output shaft of the motor, the motor is connected to the vibration transmitting body, and the output shaft of the motor is configured to drive the eccentric block to rotate to generate a radial exciting force along the radial direction of the output shaft, and the radial exciting force is used to generate vibrations parallel to the axial direction of the vibration head and parallel to the axial direction of the amplitude limiting member. Due to the design of the amplitude limiting member, the vibration parallel to the axial direction of the amplitude limiting member is limited within a preset amplitude range, so that the vibration is mainly generated in the axial direction parallel to the vibration head, and the controllability is good.
[0016] In a feasible solution, the radial exciting force is in the range of 3N-10N. The radial exciting force in this range has a significant stimulation effect, significantly increases tears, and can effectively relieve symptoms such as dry eyes and fatigue. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The technical solution of the present utility model is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0026] refer to Figures 1 to 4 The vibration therapy device of one embodiment of the utility model includes a housing 100 , a vibration head 200 , a vibration transmitting body 300 , an amplitude limiting component 400 , and a vibration driving component 500 .
[0027] The vibration head 200 includes an excitation end 210 and a connection end 220 . The excitation end 210 extends out of the housing 100 , and the connection end 220 is connected to the vibration transmission body 300 .
[0028] The vibration transmitting body 300 is located in the housing 100 and supported on the amplitude limiting member 400 .
[0029] The amplitude limiting member 400 is located in the housing 100, with one axial end connected to the vibrator 300 and the other axial end connected to the housing 100. The amplitude limiting member 400 is used to limit the suspended vibration of the vibrator 300 along the axial direction of the amplitude limiting member 400 to within a preset amplitude range.
[0030] The vibration driving member 500 includes a motor 510 and an eccentric mass 520. The motor 510 includes a motor housing 511, a stator and a rotor (not shown) disposed in the motor housing 511, and an output shaft 512 connected to the rotor of the motor 510. The motor housing 511 is connected to the vibration transmitting body 300. The output shaft 512 is connected to the eccentric mass 520.
[0031] When the motor 510 is working, the output shaft 512 of the motor 510 drives the eccentric mass 520 to rotate to generate a radial exciting force along the radial direction of the output shaft 512 of the motor 510 (formed by the inertia force generated by the rotation of the eccentric mass 520). The exciting force is transmitted to the motor housing 511 by the output shaft 512 of the motor 510, and directly drives the vibration transmitter 300 connected to the vibration head 200 to vibrate along the axial direction of the vibration head 200, so that the excitation end 210 of the vibration head 200 applies vibration excitation along the axial direction of the vibration head 200.
[0032] Specifically, the radial exciting force is generated parallel to the axial direction of the vibration head 200 (eg Figure 3 The X-axis direction shown in FIG. 4 ) and the axial direction parallel to the amplitude limiting member 400 (as shown in FIG. Figure 3 The Z-axis direction shown in FIG. 1 will not produce vibrations parallel to the direction shown in FIG. Figure 3 The vibration in the Y-axis direction shown. Due to the design of the amplitude limiting member 400, the vibration in the axial direction parallel to the amplitude limiting member 400 (i.e., vibration in the Z-axis direction) is limited to a preset amplitude range (preferably within an amplitude range of ±1 mm, more preferably within an amplitude range of ±0.5 mm), so that the vibration is mainly generated in the axial direction parallel to the vibration head 200 (i.e., vibration in the X-axis direction), that is, the radial exciting force is converted into reciprocating motion in the X-axis direction. Therefore, when using, the user can place the excitation end 210 of the vibration head 200 in the nasal bone area so that it applies vibration excitation along the axial direction of the vibration head 200 to stimulate the lacrimal gland nerve to produce tears. Not only is the therapeutic effect good, but the vibration controllability is also enhanced, the vibration reduction effect is good, and the noise is low.
[0033] The calculation formula of the radial exciting force is as follows:
[0034] F=mrω=(W / g)*r*(2πn / 60)
[0035] Wherein, F represents the radial exciting force, in N; m represents the mass of the eccentric mass 520, in Kg; r represents the eccentricity of the eccentric mass 520, in m; ω represents the angular velocity of the eccentric mass 520, in rad / s; W represents gravity, in N; g represents the acceleration of gravity, in m / s2; and n represents the rotation speed of the eccentric mass 520, in r / min.
[0036] Preferably, when the frequency of the motor 510 is in the range of 200 Hz-300 Hz, the radial exciting force F is in the range of 3N-10 N. The radial exciting force in this range has a significant stimulation effect, tears increase significantly, and can effectively relieve symptoms such as dry eyes and fatigue.
[0037] In practice, the material density, eccentricity, and size of the eccentric block 520 can be determined according to the exciting force range (3N-10N). Then, the starting torque and rated torque of the motor 510 can be determined according to the mass m and eccentricity r of the selected eccentric block 520 to calibrate the characteristic curve of the motor 510.
[0038] The calculation formula of the starting torque of the motor 510 is as follows:
[0039] M=m*g*r
[0040] Wherein, M represents the starting torque, m represents the mass of the eccentric mass 520 , g represents the acceleration of gravity, and r represents the eccentricity of the eccentric mass 520 .
[0041] Accordingly, the rotation speed of the motor 510 may be determined according to the frequency range (200 Hz-300 Hz).
[0042] To ensure that the motor 510 starts smoothly and operates at a constant speed, the motor 510 is also electrically connected to the circuit board 600. The circuit board 600 outputs a corresponding voltage value according to the characteristic curve of the motor 510, thereby controlling the motor 510 to start smoothly and operate at a constant speed at the rated operating speed.
[0043] The circuit board 600 is also electrically connected to the battery 700. Preferably, the battery 700 is a lithium-ion battery, and the housing 100 is provided with a USB charging port 101 connected to the circuit board 600 for repeated charging.
[0044] Specifically, in this embodiment, the housing 100 includes a first half shell 110 and a second half shell 120. The first half shell 110 and the second half shell 120 are buckled with each other and can be fixedly connected by screws. Of course, in other embodiments, the first half shell 110 and the second half shell 120 can also be fixedly connected in other ways, and even the housing 100 can also be integrally formed.
[0045] The first half shell 110 and the second half shell 120 are enclosed together to form a receiving chamber 102 for receiving the vibration transmitting body 300, the amplitude limiting member 400, the vibration driving member 500, the circuit board 600 and the battery 700. The USB charging port 101 is provided on one side of the second shell 120. Furthermore, a notch 103 is provided on the other side of the second shell 120 for allowing the excitation end 210 of the vibration head 200 to extend out of the shell 100.
[0046] Also refer to Figures 3 to 5 In this embodiment, the vibration head 200 is roughly bullet-shaped, and its excitation end 210 is a free end. The excitation end 210 preferably has a conical smooth outer surface to gently contact the user's nose skin.
[0047] The vibration transmission body 300 includes a fixedly connected pressure bridge 310 and a floating bracket 320. The pressure bridge 310 is fixedly connected to the vibration head 200, preferably integrally connected, to enhance the connection strength between the pressure bridge 310 and the vibration head 200, and can directly transmit vibration, with higher vibration efficiency. The floating bracket 320 is connected to the amplitude limiting member 400. The motor 510 is arranged between the floating bracket 320 and the pressure bridge 310.
[0048] Specifically, the pressure bridge 310 is roughly U-shaped, including a strip-shaped pressing portion 311 and a first arm 312 and a second arm 313 respectively connected to both ends of the pressing portion 311. The pressing portion 311, the first arm 312 and the second arm 313 together enclose a first groove 314. The first arm 312 is connected to the connecting end 220 of the vibration head 200. The side of the second arm 313 is not connected to other components.
[0049] The floating bracket 320 is generally plate-shaped, and has a second groove 321 formed thereon that is aligned with the first groove 314. The motor housing 511 of the motor 510 is received in the first groove 314 and the second groove 314, and the installation is stable and reliable. In addition, the first groove 314 and the second groove 321 also help to reduce the weight of the vibration transmission body 300 and reduce the noise caused by the vibration of the vibration transmission body 300.
[0050] Preferably, at least one weight-reducing groove 322 is provided on the floating support 320, for example Figure 5 As shown, a right-angled weight-reducing groove 322 is opened at one end of the floating bracket 320 to further reduce the weight of the floating bracket 320 and reduce the noise caused by the vibration of the floating bracket 320, thereby achieving lightweight products and easier use.
[0051] In this embodiment, the pressure bridge 310 and the floating bracket 320 are connected to the floating bracket 320 by connecting members (not shown, such as screws) through the first arm 312 and the second arm 313 of the pressure bridge 310 until they are connected to the floating bracket 320 to achieve fixed connection. Preferably, the connection position of the pressure bridge 310 and the floating bracket 320 is close to one side of the output shaft 512 of the motor 510 (compare Figure 3 and Figure 4 ), that is, the side close to the eccentric block 520. This can further reduce the vibration caused by the rotation of the eccentric block 520. In the present embodiment, the eccentric block 520 is cylindrical and is provided with an eccentric hole 521 for connecting with the output shaft 512 of the motor. In other embodiments, the eccentric block 520 may also adopt other shapes, such as a fan shape, etc., which will not be described here. It can also be understood that in other embodiments, the pressure bridge 310 and the floating bracket 320 may not be designed as separate bodies, but may be integrally formed to avoid problems such as connection failure caused by vibration.
[0052] Preferably, an amplitude limiting member 400 is respectively provided at the four corners of the floating bracket 320. Specifically, a connecting block 323 is protruded from one side of the floating bracket 320 opposite to the weight reducing groove 322, two first connecting holes 324 are provided at intervals on the bottom of the weight reducing groove 322, and two second connecting holes 325 are provided at intervals on the connecting block 323. The first connecting hole 324 and the second connecting hole 325 are used to connect with the corresponding amplitude limiting member 400.
[0053] Thus, the amplitude limiting members 400 are distributed between the floating bracket 320 and the housing 100 at intervals, and a more uniform vibration reduction effect can be achieved for each part of the floating bracket 320. It can be understood that the four amplitude limiting members 400 in this embodiment are only shown as an example. In other embodiments, the amplitude limiting members 400 can also be used in other quantities, such as 1, 2, 3, 5, 6, etc.
[0054] In this embodiment, the amplitude limiting member 400 is made of a deformable elastic material (such as silicone). Figure 5 As shown, the amplitude limiting member 400 includes a first connecting portion 410 for connecting to the shell 100, a second connecting portion 420 for connecting to the vibration transmitter 300, and a columnar main body portion 430 connected between the first connecting portion 410 and the second connecting portion 420, and the axial direction of the amplitude limiting member 400 is codirectional with the rotation center axis of the columnar main body portion 430.
[0055] Thus, when the motor 510 is working, the vibration parallel to the axial direction of the amplitude limiting member 400 can be offset by the deformation of the columnar main body 430 of the amplitude limiting member 400 and limited to a preset amplitude range. Preferably, the main body 430 is cylindrical to enhance the deformation flexibility of the main body 430.
[0056] Preferably, each of the amplitude limiting members 400 is provided with a through hole 440 penetrating the amplitude limiting member 400 in the axial direction, so as to further improve the deformation flexibility of the amplitude limiting member 400 along the direction of its own rotation center axis and achieve a better shock absorption effect.
[0057] In this embodiment, the first connection portion 410 and the second connection portion 420 of the amplitude limiting member 400 are constructed as annular grooves recessed at both axial ends of the amplitude limiting member 400, wherein the annular groove of the first connection portion 410 is used to be inserted into the first connection hole 324 or the second connection hole 325 of the floating bracket 320, and the annular groove of the second connection portion 420 is used to be connected to the shell 100.
[0058] It is understandable that in other embodiments, the first connection portion 410 and the second connection portion 420 of the amplitude limiting member 400 may also adopt other shapes / structures, as long as they can be connected to the floating bracket 320 and the housing 100. In addition, the main body 430 of the amplitude limiting member 400 may also adopt other structures, such as prism, sphere, cone, etc., which will not be described in detail here.
[0059] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact via an intermediate medium.
[0060] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
