Description

Technical Field

[0001] The invention belongs to the technical field of massagers, and in particular relates to a massage device. Background Art

[0002] Sex massagers are a type of massage device designed for adults, which aims to provide a more private and comfortable experience by imitating the touch and movement of manual massage. This type of device is widely used to enhance the individual's physical and mental pleasure, relieve stress, and promote self-exploration, helping users to relax and enjoy comfortably in a private environment.

[0003] Most existing body massagers use a fixed structure design and lack sufficient joints or flexible connections, which makes it difficult for them to conform to the natural curves of the human body during use, especially to adapt to the slight arcs and angle changes in the massage area. This fixed structure design often cannot fit the complex shape of the body during operation, causing the contact between the massager and the sensitive area to be not gentle or precise enough. Specifically, the contact between the massager and the human body may cause excessive friction or too concentrated pressure, which not only reduces the comfort of the massage, but may even cause discomfort or slight fatigue. Summary of the invention

[0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a massage device.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] See also Figure 1-Figure 14 As shown, the specific embodiments provided by the present invention are as follows:

[0056] refer to Figure 1 As shown, the massage device includes a drive assembly 1, which is used to provide power output. The drive assembly 1 mainly includes a rotating motor 101 and a gear box 102, which cooperate with each other to achieve a stable and efficient transmission effect.

[0057] The rotating motor 101 is used as a core power source, and its output shaft is connected to the input end of the gear box 102. The rotating motor 101 generates a rotational motion after being powered on, and transmits power to the gear box 102.

[0058] The gear box 102 is used to adjust the output speed and torque of the rotary motor 101 to meet the needs of different massage modes. The gear box 102 is provided with multiple sets of gear transmission mechanisms. These gears can be configured with different speed ratios to decelerate or speed up the rotary motion to ensure that the output power is stable and controllable. At the same time, the output end of the gear box 102 is connected to the rotary transmission assembly 2 of the massage device so that the rotary motion can be accurately transmitted.

[0059] refer to Figures 2 to 4As shown, the rotary transmission component 2 is connected to the drive component 1 and is driven by the drive component 1 to rotate along an axis X. The axis X should be understood as defining the rotation centerline of the rotary transmission component 2, that is, the axial direction in which the rotary motion occurs. The rotary transmission component 2 rotates around the axis X under the action of the drive component 1.

[0060] Furthermore, the rotation transmission assembly 2 is composed of a plurality of offset portions 203, and these offset portions 203 are offset in different directions around the axis X. Here, the offset portion 203 should be understood as a mass point formed on the path of the rotation transmission assembly 2, and each mass point represents a component of the rotation transmission assembly 2. Countless offset portions 203 constitute the overall structure of the rotation transmission assembly 2, rather than referring to its motion path.

[0061] refer to Fig.15 As shown, at a specific position of the axis X, the corresponding offset portion 203 has a single offset direction. The offset portion 203 corresponding to the specific position of the axis X is specifically, at a specific position of the axis X, and on a section Y perpendicular to the axis X, the multiple intersections of the rotary transmission component 2 and the section Y are the offset portions 203 at the specific position. Among them, these intersections, i.e., these offset portions 203, have a unified offset direction, i.e., they are consistent when away from the direction of the axis X. Specifically, at a certain position of the axis X, the offset portion 203 at this position is only offset in a certain direction, and there will not be offsets in multiple directions at the same time. That is to say, at each specific position, the offset direction of the offset portion 203 is unique, and there will be no overlap of multiple offset directions.

[0062] In addition, in this embodiment, it is required that at a specific position of the axis X, on the cross section Y perpendicular to the axis X, the offset portion 203 formed by the multiple intersections of the rotation transmission assembly 2 and the cross section Y must have the same offset direction, that is, they are all facing the same side away from the axis X. If the offset directions of these intersections are inconsistent, for example, some intersections are offset to one side away from the axis X, while other intersections are offset to the other side away from the axis X, this situation does not meet the requirements of this embodiment and is not within the protection scope of this embodiment.

[0063] In a specific embodiment, the rotation transmission component 2 is a rod-shaped member or a sheet-shaped member, which is an overall slender structure and can rotate around the axis X.

[0064] refer to Figure 8 As shown, the structure of the rod-shaped member is arranged along a spiral ascending path, which means that the shape of the rod-shaped member is not a simple straight line or planar structure, but is distributed in a spiral shape around the axis X, so that it can produce a continuous and smooth offset motion during the rotation process.

[0065] In this example, the offset portion 203 should be understood as any point on the spiral path, that is, countless particles constituting the spiral structure. Since the spiral structure itself has a certain radial offset relative to the axis X, these particles have different offsets at different positions and together form the overall structure of the rotary transmission component 2. At any specific position of the axis X, the corresponding offset portion 203 has only a single offset direction, that is, the particles at this position are offset along the tangent direction of the spiral path, and will not be offset in multiple different directions at the same time.

[0066] For example, the structure of the rod-shaped member or the structure of the sheet-shaped member is in an S-shaped or quasi-S-shaped path. This means that the rod-shaped member or the sheet-shaped member is not a straight line or a spiral in a single direction, but presents a curved path similar to an S-shaped in the direction of the axis X, so that it can generate complex and varied offset motions during the rotation process.

[0067] In this example, the offset portion 203 should be understood as countless particles distributed along an S-shaped or quasi-S-shaped path. Due to the characteristics of the S-shaped structure, each particle has a different degree of offset relative to the axis X, and together constitutes the overall shape of the rotation transmission component 2. At any specific position of the axis X, the corresponding offset portion 203 has only a single offset direction, that is, the direction of the particle offset at this position is determined, and it will not be offset in multiple directions at the same time.

[0068] refer to Figures 9 to 10 As shown, exemplarily, the structure of the rod-shaped member is a linear path, that is, the main form of the rod-shaped member extends as a straight line along the axis X direction. However, on the circumferential wall surface of the rod-shaped member, there are prismatic structures 201 protruding from the circumferential wall surface. These prismatic structures 201 are distributed along the surface of the rod-shaped member and present a spiral path form. That is, these prismatic structures 201 rise in a spiral along the circumferential wall surface of the rod-shaped member, forming a surface feature similar to a spiral protrusion.

[0069] In this example, the offset portion 203 should be understood as any point on the prismatic structures 201. Since the prismatic structures 201 are spirally shaped and protrude along the surface of the rod-shaped member, these structures will produce different offset effects during the rotation process. Specifically, a certain point of each protruding prismatic structure 201 will deviate outward and form an offset direction along the spiral path.

[0070] Exemplarily, the structure of the rod-shaped member is a linear path, that is, the rod-shaped member extends in a straight line in the direction of axis X. Meanwhile, discontinuous local protruding structures 202 are provided on the circumferential wall surface of the rod-shaped member, and these protruding parts partially protrude from the circumferential wall surface of the rod-shaped member.

[0071] These local protrusion structures 202 are not evenly distributed along the entire circumference, but are distributed on the surface of the rod-shaped member in an interval manner, forming a discontinuous protrusion pattern. These protrusions will produce different contact effects during the rotation process, providing a varying massage force and contact feeling.

[0072] In this example, the offset portion 203 is each protruding point of the local protruding structures 202 during the rotation process.

[0073] refer to Figures 5 to 6 As shown, it includes a supporting keel 3. The supporting keel 3 has an inner cavity 301 and an outer supporting wall 302.

[0074] The inner cavity 301 is used to install and accommodate the rotary transmission component 2. The outer support wall 302 carries the driving movement of the rotary transmission component 2 and contacts the human body tissue, ensuring that the massage force generated during the movement of the rotary transmission component 2 can be transmitted to the human body surface, thereby achieving an effective massage effect.

[0075] In a specific embodiment, the support keel 3 is a spring structure. The inner cavity 301 should be understood as the internal space of the spring structure, which is used to accommodate and install the rotary transmission component 2. The inner cavity 301 of the spring structure has a certain elasticity and variability in shape, and can be deformed to a certain extent according to the movement trajectory of the rotary transmission component 2 and the movement direction of the offset portion 203. The external support wall 302 should be understood as a part of the spring structure, that is, it constitutes the outer layer of the spring structure and has certain elastic properties. Since the support keel 3 is a spring structure as a whole, its external support wall 302 can produce elastic deformation when driven by the rotary transmission component 2, and adapt to the contact pressure of human tissue through the deformation, making the massage process softer and more comfortable. The elasticity of the external support wall 302 not only helps to disperse the massage force and avoid discomfort caused by excessive local pressure, but also can be adaptively adjusted with the movement of the rotary transmission component 2, thereby improving the dynamic response capability of the massage device.

[0076] In addition, the elastic properties of the external support wall 302 enable it to provide a buffering effect during the massage process. When the offset portion 203 of the rotating transmission assembly 2 touches the external support wall 302, the external support wall 302 will generate a certain feedback force due to elastic deformation, making the overall contact feel of the massage device more natural and reducing the stiff mechanical feel.

[0077] refer to Figure 4 As shown, the offset distance d of at least part of the offset portion 203 is i The minimum distance r from the edge of the inner cavity 301 of the spring structure at the corresponding position of the axis X to the central axis X is greater than minIt should be understood that, during the movement of the rotating transmission assembly 2, at least part of the offset distance d of the offset portion 203 i , that is, the maximum offset of the offset portion 203 relative to the central axis X is greater than the minimum distance r from the edge of the inner cavity 301 of the spring structure to the central axis X. min In other words, when the rotary transmission component 2 rotates, the position of some offset parts 203 will exceed the range of the edge of the spring structure inner cavity 301 closest to the central axis X. This means that the rotary transmission component 2 will periodically contact or act on the inner wall of the spring structure during movement, thereby causing the spring structure to deform or react to force.

[0078] Specifically, when the spring structure is driven by the rotary transmission assembly 2 and subjected to external contact pressure, the spring structure will overall present morphological changes in multiple directions or dimensions.

[0079] In the radial direction, the spring structure as a whole will present a dynamic morphological change of wave-like fluctuation. Specifically, when the rotary transmission assembly 2 moves, its offset portion 203 will periodically apply a force, causing the outer support wall 302 of the spring structure to produce an undulating deformation in the radial direction.

[0080] Combined with the characteristics of the spring structure, the spring structure has natural elasticity and flexibility, and can dynamically adjust the strength according to the periodic force applied by the offset portion 203 of the rotary transmission assembly 2. When the rotary transmission assembly 2 moves, the force of the offset portion 203 will periodically push the spring structure to produce fluctuations in the radial direction. This wave-like fluctuation brings about gradually changing pressure, which can effectively avoid problems such as single pressure and uneven intensity that may occur in traditional massage equipment. Through this natural adjustment of force, the massage device can automatically adjust the massage strength according to demand, thereby ensuring comfort and diversity during the massage process.

[0081] The wave-like undulation of the spring structure enables the outer support wall 302 to dynamically change shape to better fit the curves of the human body and the tissue layers of different parts. This fit improves the efficiency of the massage while reducing the discomfort that may be caused by poor contact. For example, in more sensitive parts, the undulation can avoid excessive pressure concentration and provide a softer massage effect; while in harder parts, the undulation may provide a deeper massage effect.

[0082] This change in force makes the massage no longer a single linear one. Instead, it produces varying massage intensities in different time periods through wave-like fluctuations, thereby making deep muscle relaxation more balanced and avoiding the discomfort that may be caused by a single depth massage.

[0083] The wave-like change of the spring structure in the radial direction is not just a simple change in force, but also includes local adaptive adjustment. Depending on the massage part, the spring structure can achieve local pressure changes through slight deformation. This change can adjust the force in time according to the actual situation, and the massage intensity obtained by different parts is more personalized. This adaptive and pressure adjustment ability greatly improves the flexibility and comfort of the massage device, ensuring that each part can obtain appropriate force adjustment during the massage process, avoiding discomfort caused by excessive or weak force.

[0084] Exemplarily, the outer support wall 302 of the spring structure of the support keel 3 in the cross section S perpendicular to the axial direction is circular. It should be understood that the outer support wall 302 of the spring structure of the support keel 3 in the cross section S perpendicular to the axial direction is circular, that is, when the support keel 3 is observed from the vertical direction of the rotation axis of the rotation transmission component 2, the cross-sectional shape of the outer support wall 302 is a circle. This means that the outer support wall 302 of the support keel 3 is not angular or irregular in shape, but is a smooth circular curved surface, which helps to better contact with the human body and provide a uniform and comfortable massage effect.

[0085] Exemplarily, the shape of the inner cavity 301 is one or more of an ellipse, a rectangle, a rounded rectangle or a runway shape. That is, the inner cavity 301 supporting the keel 3 can adopt different cross-sectional shapes to meet different functional requirements according to specific design requirements. The ellipse has smooth edges, can evenly distribute pressure, and can effectively adapt to different contact areas. The rectangle provides a more straight contact surface. The rounded rectangle combines the straight line characteristics of the rectangle and the smooth transition of the circle, which can reduce the discomfort caused by sharp angles while ensuring the structural strength, and provide a more comfortable contact surface.

[0086] In a specific embodiment, the short axis of the inner cavity 301 or the short side of the rectangle is not greater than 2 / 3 of the long axis or long side. It should be understood that the short axis of the inner cavity 301 (for an elliptical inner cavity 301) or the short side of the rectangle (for a rectangular or rounded rectangular inner cavity 301) is not greater than 2 / 3 of the long axis or long side. That is, whether the inner cavity 301 is an ellipse, rectangle, rounded rectangle or other geometric shape, the length of its short axis or short side is less than or equal to 2 / 3 of the long axis or long side.

[0087] By ensuring that the short axis or short side of the inner cavity 301 does not exceed 2 / 3 of the long axis or long side, the shape and structure of the inner cavity 301 space can be effectively optimized to avoid the space being too narrow or asymmetric when accommodating internal components. This design can ensure that the components in the inner cavity 301 can move in a relatively spacious space, reducing the stuck or unstable movement of components caused by too compact a space.

[0088] Exemplarily, the spring structure is a spiral ascending structure, which means that the overall shape of the spring is spiral and gradually ascends along the axial direction, that is, each circle or each section rotates around the central axis, thereby providing relatively smooth mechanical properties.

[0089] refer to Fig.11 As shown, in a specific embodiment, each turn of the spring structure has an equal pitch and radius. This means that the pitch (axial distance between two adjacent turns) and radius (radius of the circular cross section of each turn) of each turn of the spring are constant and consistent. Due to the equality of pitch and radius, the elastic coefficient of the spring remains constant throughout the entire working range, which helps to achieve uniform force transmission and avoid uneven force distribution in different parts.

[0090] refer to Fig.12 As shown, in a specific embodiment, each circle of the spring structure is arranged in the form of one circle being larger and the other being smaller, that is, the radius between each circle of the spring gradually changes, presenting a structure of alternating increase and decrease. The radius of each circle changes alternately, so that there are different sizes between every two circles - the radius of one circle is larger, and the radius of the next circle is smaller, forming a periodic fluctuation structure. The alternating increase and decrease of the circle shape helps to improve the morphological stability of the spring. Compared with the traditional uniform design, this variable design can better disperse the stress when the spring is under force, avoid excessive load on a certain part of the spring, thereby reducing the possibility of local fatigue and damage, and increasing the service life of the spring.

[0091] refer to Fig.13 As shown, the spring structure is exemplarily composed of a plurality of elastic bodies that are not connected to each other. Each elastic body acts as an independent unit, and these elastic bodies can be physically connected by flexible connectors. Each elastic body can independently respond to external forces during the massage process, thereby providing the required elasticity and support force.

[0092] refer to Figures 13 to 14 As shown, the massage device has a one-way limiting portion 4;

[0093] The one-way limiting portion 4 has a single in-plane free bending dimension;

[0094] The one-way limiting portion 4 is arranged on the supporting keel 3; and,

[0095] The bendable plane of the one-way limiting portion 4 is parallel to the long axis or the long side.

[0096] It should be understood that, in this specific embodiment, the one-way limiting portion 4 is a key component of the massage device, which is used to control and limit certain movement directions.

[0097] Specifically, the one-way limiter 4 allows the support keel 3 to bend freely only in a specific plane, and the bending dimension is single, that is, the limiter only allows the support keel 3 to deform in a specific direction. Its function is to limit the free movement of the support keel 3 in the direction to avoid excessive movement of the device or movement path that does not meet the expected path.

[0098] The bendable plane of the one-way limiter 4 is parallel to the long axis or long side, that is, the bendable plane of the one-way limiter 4 is at a vertical angle to the long axis or long side of the support keel 3. Thus, the one-way limiter 4 can provide effective constraints to prevent the device from being displaced or deformed in an unwanted direction.

[0099] By achieving free bending in a single plane in the one-way limiter 4, unnecessary movement or deviation can be avoided. The limiter provides an effective constraint to ensure that the support keel 3 works according to the predetermined path and angle. This restrictive movement design effectively prevents irregular movement of the device during use and improves the overall stability and accuracy.

[0100] Based on this, due to the existence of the one-way limiting portion 4, the supporting keel 3 can move under the drive of the rotary transmission driving member, and this movement is similar to the serpentine movement of snakes when walking.

[0101] Specifically, the one-way limiter 4 constrains the movement direction of the support keel 3, so that it can only bend freely in a specific plane and cannot deform in other directions, which can effectively guide the movement trajectory of the support keel 3 to present a snake-like movement pattern.

[0102] The serpentine motion should be understood as imitating the motion law of snakes when walking, that is, each part of the body (supporting keel 3) bends in turn, and local thrust is output in each bending area to form a coherent and smooth bending movement.

[0103] Through the serpentine motion, the support keel 3 can better adapt to the different curves of the human body, especially during the massage process, it can fit the sensitive parts of the human body and achieve a squeezing massage effect (it should be understood that during the movement of the curved area of ​​the support keel 3 protruding toward the part to be massaged and sinking away from the part to be massaged, the curved area provides a massage effect similar to squeezing and patting to the part to be massaged). This serpentine-like motion mode increases the flexibility and adaptability of the massage device and can better handle body parts with complex shapes.

[0104] The wave-like propulsion method of the serpentine motion can effectively disperse the massage force, avoid concentrating it on a certain point or area, and provide a more uniform squeezing massage feeling.

[0105] The serpentine motion design allows the device to exhibit a smooth and continuous motion trajectory when working, avoiding abrupt or unnatural movements of the device. This smooth motion feeling not only improves the operating stability of the device, but also greatly enhances the comfort of the massage process, avoiding possible friction or discomfort.

[0106] In a specific embodiment, the one-way limiter 4 is a sheet or plate-like structure and is arranged on one or both sides of the short side or short axis of the support keel 3. The bendable plane of the sheet or plate-like structure, i.e., the wider plane, is parallel to the long side or long axis. The support keel 3 can pass through the sheet or plate-like structure to form a sliding connection.

[0107] In a specific embodiment, the one-way limiting portion 4 may also be provided on one or both sides of the long side or long axis of the supporting keel 3. The supporting keel 3 is slidably connected to the bendable plane of the one-way limiting portion 4 (e.g., a slot of a certain width is provided on the bendable plane, and the outer supporting wall 302 of the supporting keel 3 is located in the slot).

[0108] As shown in the reference figure, the massage device includes a massage head 5. The massage head 5 is connected to the end of the support keel 3. When the support keel 3 performs a serpentine motion, the massage head 5 synchronously follows the swing, thereby providing a squeezing massage effect on the massaged part, especially the cave-shaped part to be massaged on the human body.

[0109] In a specific embodiment, a stimulation device is disposed inside the massage head 5. For example, the stimulation device is a vibration motor for providing vibration massage stimulation.

[0110] The massage device has an elastic layer, such as a silicone material, which wraps the entire massage device. This elastic layer is not just a cover for the appearance, it will closely cooperate with the serpentine movement of the support keel 3 and respond to the movement of the support keel 3 synchronously.

[0111] Specifically, the elastic layer is the surface part of the massage device, wrapped around the entire device, and provides a direct contact experience for the user. The material of the skin layer, such as silicone, has good softness and adaptability, can provide a comfortable touch, and has sufficient elasticity and flexibility to respond to the movement of the supporting keel 3.

[0112] When the support keel 3 performs serpentine motion under the action of the rotating transmission drive member, the elastic layer will synchronously follow this motion change. That is to say, as the support keel 3 moves in a wave-like manner or is partially bent, the skin layer will also undergo corresponding deformation in the same direction, so that the surface of the entire device fits the human body smoothly and provides a better massage effect. This synchronous serpentine motion means that the deformation and movement of the elastic layer will be consistent with the serpentine path of the support keel 3, which not only improves comfort, but also increases the accuracy and uniformity of the massage.
