Description

Technical Field

[0001] This invention relates to the field of physiotherapy technology, and more specifically, to a massage device. Background Technology

[0002] Massage is a common and ancient form of physical therapy. Massage applies mechanical energy, such as vibration, to appropriate parts of the body to increase the temperature of the massaged area, promote blood circulation, relax muscles, relieve local spasms and pain, and stimulate the body's nerves. This, in turn, improves the body's fluid secretion, thereby stimulating the nerves, enhancing feelings of pleasure, eliminating fatigue, and fostering a more positive mindset.

[0003] Most existing massage devices, especially small ones such as massage sticks and vibrators, generally apply vibrations to specific areas of the body through direct contact. However, this direct contact massage can potentially cause skin allergies or inflammation due to hygiene issues.

[0004] Patent application WO2015 / 039787 discloses a stimulation device with a small direct contact area with the massaged area of ​​the human body. It creates an alternating pressure field between the massaged area and the massager, generating a massage effect on the massaged area. While this stimulation device reduces contact with the human body, its chambers—including a first chamber 3, a second chamber 4, and a connecting channel 5—have significant drawbacks. First, bodily fluids, moisture from the air, and even dirt can easily enter the first chamber 3 through the second chamber 4 and the connecting channel 5. Furthermore, the connection between the first and second chambers 3 and 4 via the narrow-diameter connecting channel 5 makes cleaning difficult, hindering the removal of dirt and bacteria, leading to bacterial growth, unpleasant odors, and negatively impacting the user experience. Secondly, the stimulation device provides positive or negative pressure to the second chamber 4 through the connecting channel 5 with a small inner diameter, which causes the drive mechanism to consume a large amount of power in order to achieve the corresponding pressure field change. Not only is the energy consumption high, but the rapid airflow passing back and forth through the connecting channel 5 with a small inner diameter also easily generates noise.

[0005] Patent application WO2017174607A1 discloses a pressure wave massage device, which uses a driving device to deform the second end 12b of the cavity 12 of the pressure wave massage device, thereby causing alternating pressure changes within the cavity 12. Accordingly, the pressure wave massage device disclosed in this patent has a simpler structure, and the structure of the single cavity 12 reduces the difficulty of cleaning. However, the pressure wave massage device disclosed in this patent has several drawbacks: First, the pressure change in the cavity 12 of this pressure wave massage device comes from the deformation of the flexible diaphragm (second end 12b), making it difficult to generate a sufficiently large volume change and a sufficiently large pressure change within the cavity 12. Although the inventors claim that the volume change of the cavity 12 is not less than 1 / 8 of the minimum volume, or even greater, in actual testing, it is quite difficult to achieve a large volume change in the cavity 12 through the deformation of the flexible diaphragm; the motor requires a large energy consumption to drive the repeated deformation of the flexible diaphragm. Secondly, the pressure changes in the cavity 12 of this pressure wave massage device originate from the deformation of the flexible diaphragm (second end 12b). The high-frequency deformation of the flexible diaphragm generates significant noise, reducing the user experience. Thirdly, the drive unit of this pressure wave massage device is directly connected to the flexible diaphragm. The cavity volume changes by pressing and stretching a portion of the flexible diaphragm, causing it to deform. This means that the area where the flexible diaphragm connects to the drive unit will repeatedly deform, easily leading to excessive fatigue at the connection point and further increasing noise. Finally, the second end 12b of the cavity 12 of this pressure wave massage device is a flexible diaphragm, directly connected to the drive unit. This makes it difficult to remove and reinstall the second end 12b from the drive unit, and also prevents the first end 12a connected to the second end 12b from being replaced. This hinders the user from changing the cavity structure according to their needs and makes it inconvenient for the user to disassemble it for thorough cleaning and maintenance. Summary of the Invention

[0006] The main advantage of this invention is that it provides a massage device that, while satisfying hygiene requirements, can more easily achieve large volume changes in the cavity and generate sufficient pressure changes within the cavity.

Therefore, the above terms should not be construed as limiting the invention.

[0029] Referring to the accompanying drawings of this invention Figures 1 to 4CA massage device according to an embodiment of the present invention is described, comprising at least one massage device 10 and a drive device 20, wherein the massage device 10 includes a rigid plate 11, a massage body 12 and a foldable assembly 13, wherein a first end 131 and a second end 132 of the foldable assembly 13 are hermetically connected to the rigid plate 11 and the massage body 12, respectively, wherein the massage device 10 has a cavity 100, wherein the rigid plate 11, the massage body 12 and the foldable assembly 13 form the cavity 100, and the cavity 100 extends from the rigid plate 11 to the massage body 12, wherein the cavity 100 has an opening 1201 formed in the massage body 12, and wherein the drive device 20 is configured to drive the unfolding and folding of the foldable assembly 13, thereby causing the volume of the cavity 100 to vary between a minimum volume and a maximum volume. Preferably, to ensure a sufficiently large volume change and a sufficiently large pressure change within the cavity 100, the ratio of the minimum volume to the maximum volume of the cavity 100 is no greater than 4 / 5. Preferably, the cavity 100 of the massage device 10 of the massage apparatus of the present invention has a continuous cylindrical structure to allow gas to flow smoothly within the cavity 100. In some embodiments, the rigid plate 11 is made of a material that is not easily deformed under stress, such as hard metals or alloys, high-strength plastics, etc., to facilitate the transmission of driving force to the foldable assembly 13. In other embodiments, the rigid plate 11 is made of silicone rubber and has sufficient thickness to provide sufficient rigidity and resistance to deformation. Preferably, the rigid plate 11 and the foldable assembly 13 are made of the same material, allowing them to be integrally molded, thereby reducing the manufacturing steps and costs of both. For example, both the rigid plate 11 and the foldable assembly 13 are made of silicone rubber. Furthermore, the rigid plate 11 (and the massage body 12) and the foldable assembly 13 are both made of rubber. Preferably, the rigid plate 11, the foldable assembly 13, and the massage body 12 are configured to be airtight, so that airflow can only flow into and out of the cavity 100 through the opening 1201, thereby allowing the air pressure inside the cavity 100 to change accordingly with the change in the volume of the cavity 100 when the opening 1201 of the cavity 100 is closed.

[0030] As shown in the attached image. Figures 2A to 4CAs shown, in an embodiment of the massage device of the present invention, the cavity 100 of the massage device 10 forms a first end 101 and a second end 102, wherein the massage body 12 of the massage device 10 forms the first end 101 of the cavity 100, and the foldable component 13 forms the second end 102 of the cavity 100. In other words, since the foldable component 13 can be folded and unfolded, the volume of the second end 102 formed by the foldable component 13 can vary regularly or irregularly, thereby causing corresponding regular or irregular changes in the air pressure within the cavity 100. Preferably, the first end 101 and the second end 102 of the cavity 100 of the massage device 10 of the massage device of the present invention are both continuous cylindrical structures, so that gas can flow smoothly within the cavity 100. Preferably, the inner diameters of the first end 101 and the second end 102 of the cavity 100 of the massage device 10 of the massage apparatus of the present invention are substantially the same, and the inner diameters of the first end 101 and the second end 102 are uniform, so that gas can flow smoothly within the cavity 100 and is less prone to noise. More preferably, the inner diameter of the first end 101 of the cavity 100 of the massage device 10 of the massage apparatus of the present invention is larger than the inner diameter of the second end 102. Optionally, the first end 101 of the cavity 100 of the massage device 10 of the massage apparatus of the present invention has a trapezoidal cross-section, and the opening 1201 of the cavity 100 forms the end of the larger end of the trapezoidal cross-section. In other words, the first end 101 extends outward from the second end 102, and the inner diameter of the first end 101 gradually increases. However, the opening 1201 of the cavity 100 may also form the end of the smaller end of the frustum-shaped cross-section. Those skilled in the art will understand that variations in the shape and size of the cavity 100 should not be considered a limitation on the scope of protection of the massage device of this invention.

[0031] As shown in the attached image. Figures 2A to 4C As shown, in the massage device 10 of the massage device according to the embodiment of the present invention, the first end 131 and the second end 132 of the foldable component 13 are respectively hermetically connected to the rigid plate 11 and the massage body 12, so that one end of the second end 102 is sealed by the rigid plate 11, and the other end of the second end 102 is connected to the first end 101, thereby forming the cavity 100.

[0032] As shown in the attached image. Figures 2A to 4CAs shown, the foldable component 13 of the massage device 10 according to an embodiment of the present invention includes a set of folding units 133, wherein each folding unit 133 forms a gas channel 1330, and each folding unit 133 has a first stack 1331 and a second stack 1332, wherein the first stack 1331 and the second stack 1332 of each folding unit 133 are hermetically connected together to form an outwardly protruding first ridge 1333 and a first folding space 1334 located between the first stack 1331 and the second stack 1332, wherein the first folding space 1334 of each folding unit 133 is connected to the gas channel 1330, wherein every two adjacent folding units 133 are hermetically connected end-to-end to form an inwardly protruding second ridge 1335 and a second folding space 1336 located between the two adjacent folding units 133 and to make the gas channels 1330 of the two adjacent folding units 133 interconnected. In other words, the gas channel 1330 of the folding unit 133 of the folding assembly 13 and the first folding space 1334 connected to the gas channel 1330 together form the second end 102 of the cavity 100. Accordingly, the first folding space 1334 of the folding unit 133 of the folding assembly 13 of the massage device 10 of the present invention and the second folding space 1336 formed by each two adjacent folding units 133 allow the foldable assembly 13 of the massage device 10 of the present invention to be unfolded when the rigid plate 11 is driven to move away from the massage body 12, so as to increase the length of the gas channel 1330 of the folding unit 133 of the foldable assembly 13, the volume of the first folding space 1334 and the second end 102 to have a larger volume; and to be folded when the rigid plate 11 is driven to move closer to the massage body 12, so as to reduce the length of the gas channel 1330 of the folding unit 133 of the foldable assembly 13, the volume of the first folding space 1334 and the second end 102 to have a smaller volume. It is understood that the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the massage apparatus of the present invention can hermetically separate the first folding space 1334 from the second folding space 1335 respectively. It is understood that the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the massage apparatus of the present invention are sheet-like for easy folding. It is understood that when the foldable component 13 of the massage device 10 of the massage apparatus of the present invention is unfolded, the volume of the second folding space 1336 formed by two adjacent folding units 133 can also become larger; when the foldable component 13 of the massage device 10 of the massage apparatus of the present invention is folded, the volume of the second folding space 1336 formed by two adjacent folding units 133 can also become smaller.It is understood that the rigid plate 11 of the massage device 10 of the massage device of the present invention is driven by the driving device 20 of the massage device of the present invention to move back and forth, thereby driving the rigid plate 11 to move back and forth away from the massage body 12 and towards the massage body 12, and causing positive or negative pressure to be alternately generated in the second end 102 (especially when the opening 1201 of the cavity 100 is closed). Those skilled in the art will understand that when the massage device of the present invention is used for massage, the massage body 12 of the massage device 10 is pressed on the human body massage area and the opening 1201 of the cavity 100 is at least partially closed or blocked by the human body massage area, thereby causing the air pressure in the cavity 100 to change when the rigid plate 11 of the massage device 10 of the massage device of the present invention is driven to move back and forth. Accordingly, firstly, the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention is folded and unfolded as a whole, which allows the rigid plate 11 of the massage device to have a larger stroke and makes it easier for the second end 102 of the massage device 10 to achieve large volume changes, so as to generate sufficient air pressure changes within the second end 102. Secondly, the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention is folded and unfolded as a whole, avoiding localized, repetitive, and high-frequency deformation of the flexible diaphragm of the drive device of the pressure wave massage device in publication number WO2017174607A1, which enables less noise to be generated when the volume of the cavity 100 of the massage device 10 of the present invention changes. Furthermore, the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention is folded and unfolded as a whole. This allows the massage device of the present invention to avoid the defects of the pressure wave massage device in publication number WO2017174607A1, where the driving device acts on a local position of the flexible diaphragm, causing deformation of the flexible diaphragm by pressing and stretching, resulting in repeated deformation of the connection between the flexible diaphragm and the driving device and excessive fatigue leading to breakage. Further, the fact that the foldable component 13 of the massage device 10 of the present invention is unfolded and folded as a whole also means that when the second end 102 of the foldable component 13 changes, the stress on the connection between the folding unit 133 of the foldable component 13 and the rigid plate 11 is less, consuming less energy and being easier to implement. This avoids the connection between the foldable component 13 and the rigid plate 11 undergoing excessive repeated deformation, which could damage the foldable component 13 or even the entire massage device 10. Preferably, the first stack 1331 and the second stack 1332 of the folding unit 133 are both annular, so that the first folding space 1334 surrounds the gas channel 1330 and the second end 102 has a circular or elliptical cross-section.The first stack 1331 and the second stack 1332 of the folding unit 133 are both annular, which facilitates folding between the first stack 1331 and the second stack 1332 of the folding unit 133 and folding between adjacent folding units 133. However, the first stack 1331 and the second stack 1332 of the folding unit 133 may also be any other shape that enables the folding and unfolding of the foldable component 13. Those skilled in the art will understand that the shape of the first stack 1331 and the second stack 1332 of the folding unit 133 should not be a limitation on the scope of protection of the massage device of the present invention. Preferably, the first stack 1331 and the second stack 1332 of the foldable component 13 of the massage device 10 of the massage device of the present invention are integrally formed. More preferably, the rigid plate 11, the foldable component 13, and the massage body 12 are made of the same material and integrally formed. In other words, by increasing the thickness of the rigid plate 11 and the massage body 12, the rigidity of the rigid plate 11 and the massage body 12 can be ensured, and by reducing the thickness of the first layer 1331 and the second layer 1332 of the foldable assembly 13, it can be folded. This allows the rigid plate 11, the foldable assembly 13, and the massage body 12 to be integrally molded from the same material, thereby significantly simplifying the manufacturing process of the massage device 10 of the massage device of the present invention and reducing its manufacturing cost. This simplification of the manufacturing process of the massage device 10 of the massage device of the present invention further avoids the difficulties in connecting, fixing, and sealing the flexible diaphragm with the rigid drive mechanism and rigid wall, significantly reducing manufacturing difficulty and improving product yield.

[0033] It is worth noting that the folding unit 133 of the foldable component 13 of the massage device 10 of the massage apparatus of the present invention is made of a material with appropriate tensile strength and hardness. For example, the manufacturing material of the folding unit 133 may be rubber, polyethylene, polypropylene, polyvinyl chloride, silicone rubber, organosilicon polymer, etc. It is understood that the first layer 1331 and the second layer 1332 of the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention have appropriate thickness (the thickness of the first layer 1331 and the second layer 1332 of the folding unit 133 should not be too large or too small: if the thickness of the layers of the folding unit 133 is too large, it is not easy to fold; if the thickness of the layers of the folding unit 133 is too small, it is not easy to form). Exemplarily, the tensile strength of the manufacturing material of the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the massage apparatus of the present invention is not less than 4 MPa. It is understood that the greater the tensile strength of the manufacturing materials of the first layer 1331 and the second layer 1332 of the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention, the smaller the thickness of the first layer 1331 and the second layer 1332 of the folding unit 133 can be; conversely, the smaller the tensile strength of the manufacturing materials, the greater the thickness of the first layer 1331 and the second layer 1332 of the folding unit 133 should be. Therefore, the tensile strength of the manufacturing materials of the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the present invention may also be less than 4 MPa. The magnitude of the tensile strength of the manufacturing materials of the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the present invention should not be a limitation on the scope of protection of the present invention. Exemplarily, the hardness of the manufacturing material of the first layer 1331 and the second layer 1332 of the folding unit 133 of the foldable component 13 of the massage device 10 of the present invention is Shore hardness 0-60. It is understood that the lower the hardness of the manufacturing material of the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the present invention, the greater the thickness of the first layer 1331 and the second layer 1332 of the foldable unit 133 should be; conversely, the greater the hardness of the manufacturing material, the smaller the thickness of the first layer 1331 and the second layer 1332 of the foldable unit 133 should be. Considering that materials with higher or lower hardness may also be used to manufacture the first layer 1331 and the second layer 1332 of the foldable component 13 of the massage device 10 of the present invention, the hardness of the material should not be a limitation on the scope of protection of the present invention.It is understood that the rigid plate 11 and the foldable component 13, or even the rigid plate 11, the foldable component 13 and the massage body 12, can be integrally made of the same material, so that the rigid plate 11, the foldable component 13 and the massage body 12 can be molded in one piece, reducing the manufacturing steps of the massage device 10 of the massage device of the present invention and reducing the manufacturing cost.

[0034] As shown in the attached image. Figures 2A to 4C As shown, preferably, the outer diameter of the rigid plate 11 of the massage device 10 according to the embodiment of the present invention is not less than the outer diameter of the foldable component 13, so as to ensure that the foldable component 13 is unfolded and folded as a whole.

[0035] As shown in the attached image. Figures 2A to 4C As shown, optionally, the foldable assembly 13 of the massage device 10 according to an embodiment of the present invention further includes at least one first connector 1351, wherein the first connector 1351 is sheet-shaped and extends between the rigid plate 11 and the folding unit 133 adjacent to the rigid plate 11. Preferably, the first connector 1351 extends obliquely between the rigid plate 11 and the folding unit 133 adjacent to the rigid plate 11. Exemplarily, the first connector 1351 is formed from at least a portion of the second stack 1332 of the folding unit 133 to ensure that the foldable assembly 13 can be smoothly folded. As shown in the figures Figures 2A to 4C As shown, preferably, the first connector 1351 is hermetically sealed at the outer edge 1101 of the rigid plate 11, thereby enabling the first connector 1351 and the rigid plate 11 to form an end-folding space 1337 between them, allowing the foldable assembly 13 to be folded smoothly. It can be understood that the first connector 1351 extends from the rigid plate 11 toward the gas channel 1330. (See attached figures) Figures 2A to 4CAs shown, optionally, the foldable assembly 13 of the massage device 10 according to an embodiment of the present invention further includes at least one second connector 1352, wherein the second connector 1352 is sheet-shaped and extends between the massage body 12 and the folding unit 133 adjacent to the massage body 12. Preferably, the second connector 1352 extends obliquely between the massage body 12 and the folding unit 133 adjacent to the massage body 12. Optionally, the second connector 1352 is formed from at least a portion of the first stack 1331 of the folding unit 133 to ensure that the foldable assembly 13 can be smoothly folded. Preferably, the second connector 1352 is hermetically sealed to the inner wall 1202 of the massage body 12, thereby enabling the second connector 1352 and the folding unit 133 adjacent to the massage body 12 to form a folding space 1338 at the other end located between them, so that the foldable assembly 13 can be smoothly folded. It can be understood that the second connector 1352 extends from the inner wall 1202 of the massage body 12 toward the gas channel 1330. (See attached figures.) Figure 4D As shown, in some embodiments, the foldable component 13 of the massage device 10 according to embodiments of the present invention includes only a second connector 1352 extending obliquely between the massage body 12 and the folding unit 133 adjacent to the massage body 12. In other embodiments, the foldable component 13 of the massage device 10 according to embodiments of the present invention includes only a first connector 1351 extending obliquely between the rigid plate 11 and the folding unit 133 adjacent to the rigid plate 11.

[0036] Attached image Figure 4EThe illustration shows an optional embodiment of the foldable component 13 of the massage device 10 according to an embodiment of the present invention, wherein the foldable component 13A forms an air channel 1330A, wherein the foldable component 13A includes a first stack 1331A and a second stack 1332A, wherein one end of the first stack 1331A is hermetically connected to the rigid plate 11, and the first stack 1331A extends obliquely outward from the rigid plate 11, and one end of the second stack 1332A is hermetically connected to the massage body 1. 2. The second layer 1332A extends outward from the massage body 12 at an angle, wherein the other end of the first layer 1331A and the other end of the second layer 1332A are hermetically connected to form an outwardly protruding first ridge 1333A and a first folding space 1334A located between the first layer 1331A and the second layer 1332A, wherein the first folding space 1334A is connected to the gas channel 1330A, thereby forming the first end 101 of the cavity 100 of the foldable assembly 13. In other words, the first stack 1331A extends obliquely between the rigid plate 11 and the second stack 1332A, and the second stack 1332A extends obliquely between the massage body 12 and the first stack 1331A. The first stack 1331A and the second stack 1332A extend in different directions, but they extend towards each other, so that the first stack 1331A and the rigid plate 11 form a second folding space 1335A between them, and the second stack 1332A and the massage body 12 form a third folding space 1336A between them. This allows the first stack 1331A and the second stack 1332A to be folded and unfolded, so that the volume of the first folding space 1334A and the gas channel 1330A becomes smaller and larger. It is understood that the first layer 1331A and the second layer 1332A of the foldable component 13A of the massage device 10 of the massage apparatus of the present invention can hermetically separate the first folding space 1334A from the second folding space 1335A and the third folding space 1336A, respectively.

The annular shape of the first stack 1331A and the second stack 1332A of the foldable component 13A of the massage device 10 of the present invention also facilitates the folding of the first stack 1331A and the second stack 1332A.

This allows the first stack 1331B and the second stack 1332B to be folded and unfolded, so that the volume of the first folding space 1334B, the second folding space 1335B and the gas channel 1330B becomes smaller and larger, respectively.

The first end 131 and the second end 132 of the foldable assembly 13 are hermetically connected to the rigid plate 11 and the connecting portion 122C, respectively, and the inner wall of the connecting portion 122C is arc-shaped. Preferably, the arc angle corresponding to the arc-shaped inner wall of the connecting portion 122C is not greater than 90 degrees to reduce the obstruction of the inner wall to the free flow of air. The inner wall of the transition portion 122C of the massage device 10C of the present invention is arc-shaped, thereby making the main body portion 121C of the massage body 12C and the foldable component 13 at an angle. It is worth noting that by setting the main body portion 121C of the massage body 12C and the foldable component 13 at an angle, the folding and unfolding direction of the foldable component 13 is prevented from being in the same straight line direction as the extending direction of the massage body 12, thereby reducing the lateral dimension of the massage head of the present invention and promoting the miniaturization of the massage device. Figures 5A to 5C As shown, the cavity 100C of the massage device 10C of the massage apparatus of the present invention has a first end 101C and a second end 102. The massage body 12C of the massage device 10C forms the first end 101C, and the foldable component 13 forms the second end 102. Accordingly, the main difference between the massage device 10C of the massage apparatus according to the embodiment of the present invention and the massage device 10 is the structural difference between the massage body 12 and the massage body 12C. The structures of other structures or components of the massage device 10C are basically the same as those of the massage device 10.

As shown in the figure Figures 6A to 6D As shown, the foldable component 13D of the massage device 10 of the massage apparatus of the present invention forms the second end 102D of the cavity 100D of the massage device 10 of the massage apparatus of the present invention. (See attached figures) Figures 6A to 6D As shown, the foldable component 13D of the massage device 10 of the massage apparatus of the present invention includes a flexible bag 133D and a set of support rings 134D, wherein the support rings 134D are spaced apart and supported on the inner wall of the flexible bag 133D, and the axis of the support rings 134D is perpendicular to the extending direction of the flexible bag 133D, thereby enabling the foldable component 13D to be unfolded and folded. Accordingly, as shown in the figures... Figure 6B As shown, when the foldable component 13D is unfolded, the flexible bag 133D is stretched or pulled under the support of the support ring 134D, and the volume of the two ends 102D of the cavity 100D is increased; as shown in the attached figure. Figure 6C As shown in the figure, when the foldable component 13D is folded, the flexible bag 133D is folded under the support of the support ring 134D and the volume of the two ends 102D of the cavity 100D is reduced; as shown in the figure. Figure 6A As shown, when the foldable component 13D is in its initial state, the volume of the two ends 102D of the cavity 100D remains at its initial size under the support of the support ring 134D. It can be understood that the main difference between the massage device 10D and the massage device 10 according to this embodiment of the invention is the structural difference between the foldable component 13 and the foldable component 13D; the structures of other structures or components of the massage device 10D are basically the same as those of the massage device 10.
