Description

Technical field

[0001] The present invention relates to the field of massage devices, in particular an insertable vibration massage device for stimulating certain areas of the body. State of the art

[0002] Existing insertable vibration massage devices have a typical design flaw: their vibration unit is positioned exclusively at the tip of the massager. This fixed position of their vibration source and the singular vibration mode cannot provide compound stimulation that varies dynamically in both spatial position and vibration parameters. The vibration generated by this singular vibration source only covers its limited contact area with the body part (e.g., a cavity area), making it difficult to stimulate multiple sensitive target points within the cavity simultaneously. It is also difficult to provide effective vibration to two or more spatially separated target areas within the cavity at the same time, and it is difficult to achieve a spatially layered (e.g.,to deliver different stimulation intensities at different depths or radial positions within the cave) or a varied composite stimulation experience (e.g., dynamic switching of vibration frequency and amplitude or the synergistic effects of multi-point vibrations). Content of the present invention

[0003] To solve the aforementioned problems of the prior art, the present invention provides a vibration massage device.

[0004] To solve the aforementioned problems, the following technical solution is used in the present invention: a vibration massage device, including: a shaft body, wherein the shaft body is connected to at least a first stimulation head and a second stimulation head, where the cross-sectional area of ​​the first and second stimulation heads exceeds that of the shaft body, and wherein at least one of the first stimulation head and the second stimulation head is internally equipped with a vibration device.

[0005] The present invention solves the problems of the prior art, which are characterized by monotonous stimulation modes and limited effectiveness.

Detailed descriptions

[0006] With reference to Fig. Sections 1 to 8 describe the specific embodiments of the present invention as follows: As in Fig. 1 and Fig. Figure 2 shows an embodiment of a vibration massage device. This vibration massage device can be used to massage parts of the human body, for example, cavity-like areas. The vibration massage device comprises a base 1, an associated shaft body 2, and a stimulation structure located at the distal end of the shaft body 2. In particular, the shaft body 2 serves as a component that connects the base 1 with the stimulation structure and has an overall slim shape with an effective insertion length of 80 mm to 150 mm in order to achieve effective contact with a target area.

[0007] In a specific embodiment, the shaft body 2 has a non-linear design and exhibits a curved shaft construction with a specific curvature, which facilitates better adaptation to the natural contours of internal cavities of the body, thereby enabling the distal stimulation head to come into contact with and act on specific target areas more easily and precisely after insertion of the vibration massage device.

[0008] To balance structural strength and user comfort, the cross-sectional shape of the shaft body 2 is preferably elliptical, with a ratio of its longitudinal axis to its short axis between 1.1 and 1.5. Alternatively, it can also be circular or polygonal (e.g., rectangular). The cross-sectional dimension of the shaft body 2 can remain constant along its length or gradually increase or decrease from one end to the other.

[0009] The shaft body 2 is manufactured from a material with predefined flexibility, for example, medical-grade silicone. This material ensures that the shaft body 2 retains its characteristic curved shape without external force and is simultaneously elastically deformable under the influence of an external force. For example, if a lateral force of 5 N is applied to the distal end of the shaft body, the displacement is between 5 mm and 15 mm, with the plastic deformation after removal of the force not exceeding 2%.

[0010] The shaft body 2 comprises a first end 201 and a second end 202. The first end 201 serves as a connecting end to the base 1, while the second end 202 is the end facing away from the base 1.

[0011] In particular, the first end 201 is connected to the base 1, preferably via an integrated form connection. After the connection, the first end 201 functions as a fixed end.

[0012] The second end 202 serves as a free end for connection to a stimulation structure, thereby enabling a significant displacement or vibration of the second end 202 under the influence of an external force.

[0013] The shaft body 2 is connected to the base 1 at a preset angle. In one embodiment, this connection is perpendicular, meaning that the angle between the shaft body 2 and the base 1 is 90°. In other embodiments, the connection is inclined, with the angle being adjustable, for example, between 30° and 70°.

[0014] In one embodiment, the cross-sectional dimension of the first end 201 is said to exceed that of the remaining main body part of the shaft body 2, forming a stable connection between the first end 201 and the base 1. Here, a stable connection refers to the ability to effectively resist deformation and failure under the influence of external forces and thereby reliably maintain the preset connection angle between the shaft body 2 and the base 1.

[0015] In another embodiment, the wall thickness of the first end 201 is greater than that of the remaining main body part of the shaft body 2, which increases the torsional stiffness at the connection point between the first end 201 and the base 1 and also serves to maintain the preset connection angle between the shaft body 2 and the base 1.

[0016] In a further embodiment, both the cross-sectional dimension and the wall thickness of the first end 201 are larger than those of the remaining main body part of the shaft body 2.

[0017] In one specific embodiment, the maximum cross-sectional dimension of the shaft body 2 is between 5 mm and 30 mm. Preferably, the maximum cross-sectional dimension of the shaft body 2 is 10 mm.

[0018] In one specific embodiment, the length of the shaft body 2 is between 80 mm and 150 mm.

[0019] In one specific embodiment, the angle between the shaft body 2 and the base is 190°.

[0020] In a specific embodiment, the angle between the shaft body 2 and the base 1 is between 30° and 70° to accommodate certain application scenarios. For example, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°.

[0021] In a specific embodiment, the shaft body 2 has a linear configuration to meet certain application scenarios.

[0022] In a specific embodiment, the interior of the shaft body 2 has a cavity structure 204. An elastic support rod 205 is provided within this cavity structure 204. This support rod 205 serves to maintain the curved shaft construction of the shaft body 2 and simultaneously impart flexibility and elasticity to the shaft body 2.

[0023] More precisely, its inherent stiffness, due to the flexible material of the shaft body 2 and its hollow structure 204, is insufficient to withstand the forces of gravity. Therefore, an internal elastic support rod 205 provides the core bending stiffness and shape recovery force of the shaft body 2. This ensures that the shaft body 2 maintains its curved shaft structure stably even at rest or under minor external forces (such as malfunctions or accidental contact), thus preventing excessive deformation.

[0024] Overall, the internal elastic support rod 205 enables effective control over the overall stiffness of the shaft body 2. It provides sufficient support to maintain the shape of the originally flexible hollow shaft body 2 while ensuring that it can return to its original shape after bending.

[0025] Naturally, the inner support rod 205 in the shaft body 2 with its cavity structure 204 also prevents excessive flattening or collapse of the cavity and thus ensures the basic structural integrity of the shaft body 2.

[0026] The material for the support rod 205 can be selected from elastic plastics such as nylon or polypropylene. Furthermore, the installation procedure for the support rod 205 can be configured in various ways: One option is a non-fixed installation, in which the support rod 205 is completely embedded in the cavity structure 204 and primarily serves an elastic support function. The other option is a fixed installation, in which its end is connected to the base 1 and additionally serves a connecting reinforcement function.

[0027] As in the Fig. As shown in Figures 5 to 6, the support rod 205 is further equipped with a cable duct 206.

[0028] The base 1 is firmly connected to the first end 201 of the shaft body 2 by integral molding or bonding. Its outer contour extends beyond that of the shaft body 2 and has an asymmetrical profile (e.g., lip-shaped). This provides the user with an easy-to-grip and stable holding area. Furthermore, the base 1 can rest against the outer surface of the body during use, preventing accidental slippage of the product into the body and thus ensuring safe use.

[0029] As in Fig. As shown in Figures 3 to 4, in a specific embodiment the shaft body 2 and the base 1 use an asymmetric (or eccentric) connection. In particular, a connection point of the shaft body 2 is offset from the geometric center of the base 1 (e.g., its center of gravity or the center of its outer contour) and positioned closer to an end or a side edge of the base 1.

[0030] In a specific embodiment, the end surface of the base 1 facing the stimulation structure has a massage structure 101 to provide massage stimulation to the area of ​​the outer body to be massaged (e.g., a marginal area of ​​a cavity-like region).

[0031] This massage structure 101 can be projections, such as one or more discrete, small raised points, granules or stripe-like ribs, which are additionally provided on the surface of the end face of the base 1.

[0032] These protrusions, through their shape and arrangement, can create specific tactile stimulation. For example, several discreet, small raised points or granules may be incorporated, concentrating pressure on a small area and thus providing a focused sensation. Alternatively, one or more strip-like ribs may be included. When the user moves the massager along the direction of the ribs, a continuous stroking or scratching sensation is generated.

[0033] The stimulation structure is located at the distal end of the shaft body 2, i.e., the end furthest from the base 1.

[0034] In this embodiment, the stimulation structure consists of two spherical stimulation heads, i.e., a first stimulation head 301 and a second stimulation head 302, which are connected at different positions along the shaft body 2. For example, one stimulation head can be positioned at the distal end of the shaft body, while the other is located in the middle of the shaft, with the two arranged parallel along the axial direction of the shaft body 2.

[0035] Alternatively, the two stimulation heads can be positioned at the distal end, but extend in opposite directions, forming a forked structure.

[0036] It should be noted that the shaft body 2 in this embodiment differs from the rod-shaped body of conventional insertable vibration massage devices. The rod-shaped body of conventional insertable vibration massage devices primarily serves to provide the length and volume for insertion, thereby filling the body's internal cavities, and through its complete insertion and movement, it achieves comprehensive stimulation of the inner walls within the cavity-like area.

[0037] In particular, each stimulation head has a massage head 401 and a connecting neck 402. The massage head 401 serves to directly touch and stimulate the area to be massaged, while the connecting neck 402 serves to connect the massage head 401 to the shaft body 2.

[0038] In particular, each massage head 401 has a spherical contour without sharp edges or textures on its outer surface to ensure smoothness upon contact.

[0039] The diameter of the massage head 401 is a configurable parameter, whereby the two massage heads can be the same size or have specific differences (e.g. one with a diameter of 20 mm and the other with 18 mm).

[0040] Furthermore, the cross-sectional area of ​​the first stimulation head 301 and the second stimulation head 302 exceeds that of the shaft body 2. This means that the first stimulation head 301 and the second stimulation head 302 can occupy a larger contact area or contact space on the area to be massaged, which serves to provide a more thorough vibration transmission and more comprehensive stimulation coverage, while the shaft body 2 primarily fulfills connection and installation functions.

[0041] Or, in a specific embodiment, the circumferential surface of the massage head 401 has stimulating protrusions. These stimulating protrusions can be multiple, with heights of 1 mm to 5 mm, and serve to increase friction during the massage and to distribute the individual contact pressure over several stimulation points.

[0042] In one specific embodiment, the diameter of each stimulation head is between 10 mm and 35 mm.

[0043] The connecting neck 402 has a curved beam structure, with one end connected to the distal end of the shaft body 2 and the other end connected to the surface of the massage head 401.

[0044] In a specific embodiment, the first stimulation head 301 and the second stimulation head 302 have an inwardly curved configuration. Specifically, the first stimulation head 301 is used as an example. The connecting neck 402 of the first stimulation head 301 is formed by an extension from the second end 202 of the shaft body 2, this extension segment 4021 forming the connecting neck 402 of the first stimulation head 301.

[0045] Furthermore, during the insertion of the vibration massager, the two stimulation heads can jointly experience a slight displacement along the axis of the shaft body 2 towards the base 1, effectively reducing resistance upon initial contact and penetration.

[0046] In a specific embodiment, the extension segment 4021 is integrally formed with the circumferential wall surface of the massage head 401. The extension segment 4021 is designed to project beyond the circumferential wall surface of the massage head 401, thereby increasing the contact area with the massage head 401 and consequently improving the connection strength.

[0047] Within the stimulation structure, namely within the first stimulation head 301 and the second stimulation head 302, at least one vibration device 5 is incorporated, for example, a vibration motor or an oscillating motor. This vibration device 5 is connected to an internal power source, such as a rechargeable battery incorporated in the base 1 or the shaft body 2, and to an electronic control module, whereby the user can control the activation, deactivation, and switching between vibration modes and intensities via buttons on the base 1 or other methods (e.g., app control, voice control).

[0048] Accordingly, in one embodiment, a vibration device 5 is provided only in one of the stimulation heads, whereby the massage stimulation is supplied from a single vibration source.

[0049] Or, in another embodiment, both the first stimulation head 301 and the second stimulation head 302 are provided with vibration devices 5. For example, a first vibration device 501 is provided in the first stimulation head 301, while a second vibration device 502 is provided in the second stimulation head 302. Consequently, the first vibration device 501 in the first stimulation head 301 and the second vibration device 502 in the second stimulation head 302 can vibrate independently of each other or in a coordinated manner.This dual, independently controllable vibration system enables the vibration massager in this embodiment to provide an extremely diverse, customizable and multifaceted vibration stimulation experience (this includes independent control of two vibration modes and several preset combinations, allowing users to set the frequency, amplitude and activation and deactivation times of each vibration device via electronic devices), which far surpasses the effects that can be achieved with a single vibration source or two synchronized vibration sources.

[0050] Based on the two embodiments described above, the contact surface is spherical because the first stimulation head 301 and the second stimulation head 302 make contact with the area to be massaged (especially the cavity-like areas) via a spherical design. This avoids local pressure concentration caused by sharp points or edges, as would occur with contact ends with points, making the stimulation gentler and safer. Furthermore, the mechanical vibration energy generated by the internal vibration device 5 is distributed evenly across the spherical surface, thus avoiding any concentration or damping of the vibration energy that could be caused by angular or asymmetrical shapes.

[0051] On the other hand, both the first stimulation head 301 and the second stimulation head 302 possess a certain degree of mobility. In particular, when the first stimulation head 301 and the second stimulation head 302 come into contact with the inner wall of the cavity and are subjected to non-axial contact forces (such as lateral pressure from body movements or muscle contractions), they are not rigidly fixed, but can perform small inclinations and oscillations at their connection points.

[0052] In one embodiment, this range of motion allows the first stimulation head 301 and the second stimulation head 302 to deflect within a conical space of ±5 degrees from their central position.

[0053] As in Fig.As shown in Figure 8, a specific embodiment comprises an electronic control module 6 which is electrically or signal-wise connected to the first vibration device 501 and / or the second vibration device 502, thereby enabling independent control of their vibration parameters.

[0054] The vibration parameters include: activation or deactivation, vibration intensity and vibration frequency.

[0055] Especially when both the first vibration device 501 and the second vibration device 502 are present: In one application scenario, the electronic control module 6, for example, controls the first vibration device 501 to activate the vibration, while it controls the second vibration device 502 to deactivate the vibration, with both devices alternately switching the vibration on and off to generate an intermittent, alternating pulse stimulation.

[0056] Alternatively, in another application scenario, the electronic control module 6 controls the fluctuation of the vibration intensity of the first vibration device 501 and the second vibration device 502. For example, the vibration intensity of the first vibration device 501 can be relatively higher, while that of the second vibration device 502 is comparatively lower. Furthermore, the vibration intensity of the first vibration device 501 and the second vibration device 502 can alternately increase or decrease. In particular, if the vibration intensity of the first vibration device 501 gradually increases from a low level, the vibration intensity of the second vibration device 502 decreases synchronously from a high level, and vice versa.

[0057] Furthermore, in another application scenario, the electronic control module 6 controls the fluctuation of the vibration frequency of the first vibration device 501 and the second vibration device 502. For example, the vibration frequency of the first vibration device 501 can be relatively faster, while that of the second vibration device 502 is comparatively slower. In addition, the vibration frequency of the first vibration device 501 and the second vibration device 502 can alternately accelerate or decelerate. In particular, if the vibration frequency of the first vibration device 501 gradually increases from a slow state, the vibration frequency of the second vibration device 502 decreases synchronously from a fast state, and vice versa.

[0058] Especially if only one vibration device 5 is present, for example if only the first vibration device 501 is installed: In one application scenario, the electronic control module 6 controls the first vibration device 501 to generate intermittent vibrations or continuous vibrations or vibrations with continuously varying intensity or frequency, thereby providing a diverse massage experience from a single vibration source.

[0059] In another specific embodiment, a communication module 7 is included, which is designed for connection with external electronic devices 8. For example, it can establish a communication link with a computing device that has communication functions, such as the user's smartphone, tablet computer, or PC.

[0060] The communication module 7 can, for example, be wireless communication technologies such as a Bluetooth communication module, a Wi-Fi communication module, or a communication module with Near Field Communication (NFC).

[0061] Among these, the Bluetooth communication module (especially Bluetooth Low Energy, BLE) is preferred in this embodiment due to its low power consumption and convenient pairing, making it suitable for continuous data exchange over short distances. A Wi-Fi communication module, on the other hand, offers extended connection ranges and enables remote control via the internet, making it suitable for scenarios requiring remote operation. An NFC communication module can be used to facilitate the initial connection setup, for example, by allowing a mobile phone to "tap" the device to quickly wake up the application and initiate Bluetooth or Wi-Fi pairing.

[0062] The electronic control module 6 independently controls the vibration parameters of the first vibration device 501 and / or the second vibration device 502 on the basis of an audio signal received by the communication module 7.

[0063] In an application scenario, the audio signal can, for example, originate from locally stored audio files within the electronic device 8 and / or from network streaming audio that is received and played back by an application.

[0064] In particular, in the example of the simultaneous installation of the first vibration device 501 and the second vibration device 502, when a user plays a piece of music or a video in the electronic device 8, the electronic control module 6 controls the vibration parameters of the first vibration device 501 and the second vibration device 502 based on the amplitude or frequency characteristics of the audio signal of this piece of music or video. Amplitude refers to the volume or loudness of a voice, while frequency refers to the pitch or tone of the voice. For example, if the volume or pitch of the music or video increases, the vibration amplitude of the first vibration device 501 and the second vibration device 502 increases synchronously, and vice versa.For example, if the volume or pitch of the music or video increases, the vibration frequency of the first vibration device 501 and the second vibration device 502 increases synchronously and vice versa.

[0065] In another application scenario, the audio signal can be a real-time audio input captured by the microphone of the electronic device 8, with this audio input including the user's voice.

[0066] In particular, if the volume or pitch of the user's voice increases during use of the massage device, the vibration amplitude of the first vibration device 501 and the second vibration device 502 increases synchronously, and vice versa. Or, if the volume or pitch of the user's voice increases during use of the massage device, the vibration frequency of the first vibration device 501 and the second vibration device 502 increases synchronously, and vice versa.

[0067] In summary, the present invention overcomes the limitations of conventional single-point vibration by arranging a first vibration device 501 and a second vibration device 502, which are controlled independently of each other by an electronic control module 6, wherein, by the independent control of the two vibration devices, the monotonous repetitive mechanical vibration is transformed into a multi-layered dynamic tactile feedback, thereby improving the sensory experience of massage stimulation.

[0068] In a preferred embodiment, an additional device (non-vibrating device) is included, which may be provided in the first stimulation head 301 and the second stimulation head 302 or arranged in a single stimulation head. Such an additional device serves to provide additional functions beyond vibration; in particular, it may comprise the following types: The additional device is, for example, a counterweight sphere. By arranging the counterweight sphere with a specific mass (e.g., a cone-shaped sphere) in the stimulation head, the weight, rotational inertia, and overall center of gravity of the stimulation head can be changed.

[0069] Or the additional device is a sensor, such as: a pressure sensor for real-time detection of the contact pressure between the stimulation head and the body, a temperature sensor for monitoring the body surface temperature in the contact area, or an electromyography sensor for recording muscle contraction activity, which is particularly suitable for biofeedback training in conjunction with Kegel exercises.

[0070] In addition, the extra device is a mini camera for internal image recording.

[0071] Or the additional device is a heat conduction unit, i.e., a built-in heating device to provide controllable thermostimulation or thermotherapy.

[0072] Or the additional device is an electrical stimulation unit that can be used to generate microcurrents (e.g. EMS) to provide contraction stimulation at the muscle level.

[0073] Or the additional device is a fluid delivery system that dispenses lubricant or other functional fluids as needed through a built-in micropump or a squeezable fluid reservoir.

[0074] Although exemplary embodiments of the present invention have been shown and described, it will be clear to those skilled in the art that numerous variations, modifications, substitutions, and changes to these embodiments can be made without departing from the principles and spirit of the present invention. The scope of the invention is defined by the appended claims and their equivalents.
