Description

TECHNICAL AREA

[0001] The present application relates to the field of massage devices, in particular a vacuum massage structure and a massage device. STATE OF THE ART

[0002] Currently, suction massage is widely used as a form of physical massage therapy in the cosmetic field. To meet the requirements of suction massage, negative pressure massage devices are generally used. The basic principle is to generate a pressure lower than atmospheric pressure using a vacuum generator. This pressure is applied via a suction nozzle to the skin surface of the facial area being massaged, exerting a stimulating effect such as suction and lifting on the skin and subcutaneous tissue. This promotes blood circulation, relieves muscle fatigue, and improves the condition of the facial skin.However, if current vacuum massage devices are used in a humid environment created by large amounts of sweat, water vapor, or liquid substances such as applied skincare products on the skin surface of the massage area, the remaining liquid substances can easily be drawn into the interior of the massage device by the airflow during vacuum generation. This leads to the formation of hygienic dead zones or causes the vacuum generation device to become damp and short circuits to occur, thus compromising the reliability of the vacuum massage device. CONTENT OF THE PRESENT INVENTION

[0003] Embodiments of the present application provide a vacuum massage structure and a massage device that can improve the reliability of the use of the vacuum massage structure.

[0004] In a first aspect, the present application provides a negative pressure massage structure comprising a negative pressure generating assembly, a first chamber, a first connecting channel, and a watertight and air-permeable assembly. The first chamber has at least one first opening that comes into contact with a point to be massaged. The first connecting channel connects the first chamber to the negative pressure generating assembly, the first connecting channel and the first chamber forming a first airflow channel. The watertight and air-permeable assembly is arranged in the first airflow channel and comprises a support element and a watertight and air-permeable membrane. The support element is connected to the inner wall of the first airflow channel, and the watertight and air-permeable membrane is arranged on the support element.The negative pressure generation assembly enables the creation of a negative pressure at the first opening via the first airflow channel, in order to create a stimulating effect on the area to be massaged through the first opening.

[0005] The aforementioned technical solution, by incorporating a waterproof and air-permeable assembly into the first airflow channel, which comprises a waterproof and air-permeable membrane and a support element, with the membrane mounted on the support element, ensures that the waterproof and air-permeable assembly can maintain stable waterproof and air-permeable function under negative pressure. This stable waterproof and air-permeable function of the assembly reduces the likelihood of liquid substances entering sections of the first airflow channel during the use of the negative pressure massage structure, thereby creating hygienic dead zones or penetrating the negative pressure generation assembly and causing short circuits. This increases the reliability of the negative pressure massage structure.

[0006] In a second aspect, embodiments of the present application provide a massage device comprising a first massage structure and the vacuum massage structure according to one of the embodiments of the first aspect, wherein the first massage structure is connected to the vacuum massage structure.

[0009] To clarify the objectives, technical solutions, and advantages of the embodiments of the present application, the technical solutions in the embodiments of the present application are described below in detail and in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are a subset of the embodiments of the present application, but not all embodiments. Based on the embodiments in the present application, all other embodiments that could be obtained by a person skilled in the art without inventive effort fall within the scope of protection of the present application.

[0010] The term "embodiment" in this application means that a particular feature, structure, or property described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this term in different places in the description does not necessarily refer to the same embodiment, nor does it represent an independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art understand, explicitly and implicitly, that the embodiments described in this application may be combined with other embodiments.

[0011] Please refer to Fig. 1 to Fig. 7. Embodiments of the present application provide a vacuum massage structure 100 comprising a vacuum generating assembly 10, a first chamber 20, a first connecting channel 30, and a watertight and air-permeable assembly 50. The first chamber 20 has at least one first opening 21 that comes into contact with a point to be massaged. The first connecting channel 30 connects the first chamber 20 to the vacuum generating assembly 10, the first connecting channel 30 and the first chamber 20 forming a first airflow channel 40. The watertight and air-permeable assembly 50 is arranged in the first airflow channel 40.The waterproof and air-permeable assembly 50 comprises a support element 51 and a waterproof and air-permeable membrane 52 with waterproof and air-permeable properties, wherein the support element 51 is connected to an inner wall of the first airflow channel 40 and the waterproof and air-permeable membrane 52 is arranged on the support element 51; wherein the negative pressure generating assembly 10 through the first airflow channel 40 enables a negative pressure to be generated at the first opening 21 in order to exert a stimulating effect on the area to be massaged through the first opening 21.

[0012] The vacuum massage structure 100 can further comprise a first housing 60 for receiving the vacuum generating assembly 10, the first chamber 20 and the first connecting channel 30, thereby protecting the individual components in the vacuum massage structure 100.

[0013] The first housing 60 can also be made of a flexible material such as silicone or liquid silicone.

[0014] The first housing 60 may have an outwardly projecting extension section 61; the end of the extension section 61 facing away from the first housing 60 has a second opening 62 which serves to make contact with the area to be massaged; the first opening 21 of the first chamber 20 may be located within the second opening 62 of the extension section 61, and the second opening 62 projects beyond the first opening 21 along the direction of projection of the extension section 61.

[0015] Since the first housing 60, made of flexible material, is relatively soft, the second opening 62 possesses deformability. The deformation of the second opening 62 increases the contact area between the vacuum massage structure 100 and the area to be massaged, ensuring a more concentrated vacuum effect, reducing ineffective leakage, and improving the massage effect. Simultaneously, the second opening 62 projects beyond the first opening 21, creating a stepped structure of first contact followed by suction. This means the second opening 62 initially distributes the pressure through large-area contact to avoid localized stinging during direct suction of the first opening 21. At the same time, the deformation of the extension section 61 absorbs the impact of the pressure, making it suitable for areas with weak muscles and thus increasing the area covered by the vacuum massage structure 100.

[0016] The vacuum generation assembly 10 can be an electric micro-suction pump. By drawing air from a closed cavity using the electric micro-suction pump, a continuous and stably adjustable vacuum environment is created to prevent discomfort caused by pressure fluctuations. The electric micro-suction pump has a fast response speed and small dimensions, making it suitable for small massage devices. It also features good control compatibility and supports PWM speed control or voltage control to implement programmable modes such as pulse and gradient modes (e.g., alternating suction and release).The vacuum generation assembly 10 can also be an electromagnetically driven vacuum unit that uses an electromagnetic coil to move a sliding magnetic block back and forth within a cylinder, changing the cavity volume by displacement to generate a vacuum. The vacuum generation assembly 10 can also employ an integrated structural design consisting of an electric micro-suction pump and a solenoid valve, for example, using a piston solenoid valve as the base structure, with the vacuum-generating cavity integrated directly into the valve body interior. The integrated vacuum generation assembly 10 allows for optimization of the assembly effect of the vacuum massage structure.

[0017] The vacuum generation assembly 10 refers to an assembly that can generate a vacuum in the first chamber 20, and not to an assembly that can only generate a vacuum in the first chamber 20. For example, the vacuum generation assembly 10 can generate a vacuum in the first chamber 20 at one time and, at another time, in conjunction with other structures and control circuit program settings, such as the setting of the exhaust position of the vacuum generation assembly 10 or the position setting of the control valve 130, or the control of the vacuum generation assembly 10, cause the first chamber 20 to have normal pressure or overpressure.

[0018] The first opening 21 can be singly or multiply. In embodiments where multiple first openings 21 are present, the multiple first openings 21 are evenly distributed on the side of the first chamber 20 facing the area to be massaged. By providing multiple first openings 21, the gas flow generated by the vacuum generation assembly 10 can be distributed over several areas, thereby increasing the massage area and thus the massage effect.

[0019] Please continue to refer to Fig. 2 and Fig. 3. The first connecting channel 30 can be a first connecting line. The first connecting line can be a hose or a flexible tube. In embodiments where the first connecting line is a hose, the two ends of the hose can be detachably connected to the first chamber 20 or the vacuum generation assembly 10, respectively, the detachable connection being either an interference fit or a threaded connection.

[0020] Please continue to refer to Fig. 4 and Fig. 5. The first connecting channel 30 can also include a first outlet section 31 and a first inlet section 32, wherein the first outlet section 31 and the first inlet section 32 communicate with each other. The first outlet section 31 can be part of the outer wall of the vacuum generating assembly 10, and the first inlet section 32 can be part of the outer wall of the first chamber 20.

[0021] A spiral groove can be provided on the inner wall of the first airflow channel 40. By providing the spiral groove, the air flowing in the first airflow channel 40 can be set into rotation. The rotating airflow can create turbulence at the point to be massaged, thus improving the massage effect.

[0022] The fact that the waterproof and air-permeable assembly 50 is arranged in the first airflow channel 40 can mean that the waterproof and air-permeable assembly 50 is arranged in the first connecting channel 30, or that the waterproof and air-permeable assembly 50 is arranged in the first chamber 20.

[0023] The waterproof and breathable membrane 52 is primarily waterproof and breathable because it contains millions of micropores, each a thousand times thinner than a human hair. Water droplets have a high surface tension and cannot penetrate these micropores, while air molecules are extremely small and can pass through freely.

[0024] When the waterproof and air-permeable membrane 52 lies close to the skin of the area being massaged, the membrane 52 is compressed and deformed during the massage, causing the micropores on the membrane 52 to close and interrupting the airflow. Therefore, in embodiments where the waterproof and air-permeable assembly 50 is located in the first chamber 20, the position of the waterproof and air-permeable assembly 50 must be chosen so that it does not come into contact with the skin of the area being massaged during the massage process.

[0025] The waterproof and air-permeable membrane 52 can be arranged on the carrier element 51 by gluing, whereby the gluing can be ultrasonic gluing, hot melt gluing or adhesive gluing.

[0026] The support element 51 can have a single-layer or a multi-layer structure. In embodiments where the support element 51 has a single-layer structure, it can be made of stainless steel or plastic. Please refer to further information. Fig. 6 and Fig. 7. The surface of the support element 51 is provided with ventilation holes 511. Several ventilation holes 511 are provided, evenly distributed on the support element 51. By providing several ventilation holes 511 on the surface of the support element 51, the support element 51 becomes permeable to air. The pore diameter of the ventilation holes 511 is R1, where 0.1 mm ≤ R1 ≤ 0.5 mm. R1 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc., or lie within a range consisting of any two of the above values.

[0027] In embodiments in which the support element 51 is made of stainless steel or plastic, the waterproof and air-permeable membrane 52 can be arranged on the support element 51 by gluing.

[0028] In the projection plane of the support element 51, the projection shape of the ventilation holes 511 can be rectangular or circular. In embodiments where the projection shape of the ventilation holes 511 is circular, the pore diameter R1 of the ventilation holes 511 can be the radius of the ventilation holes 511.

[0029] In embodiments where the support element 51 is a single-layer structure, the support element 51 can also be made of ceramic material. By controlling the process conditions during the sintering process, pores can be formed on the surface of the ceramic material, making the support element 51 permeable to air.

[0030] In embodiments in which the support element 51 is made of ceramic material, the waterproof and air-permeable membrane 52 can be arranged on the support element 51 by gluing.

[0031] In embodiments where the support element 51 is a single-layer structure, the support element 51 can also be made of a mesh material (gauze). By adjusting the mesh size of the mesh, the support element 51 becomes air-permeable.

[0032] In embodiments in which the support element 51 is made of a mesh material, the waterproof and air-permeable membrane 52 can be arranged on the support element 51 by ultrasonic bonding or hot melt bonding.

[0033] In embodiments in which the support element 51 is a multi-layered structure, the support element 51 can comprise a stainless steel layer and a mesh layer, wherein the stainless steel layer is arranged on the mesh layer by gluing.

[0034] In embodiments in which the support element 51 comprises a stainless steel layer and a mesh layer, the waterproof and air-permeable membrane 52 can be arranged on the mesh layer by ultrasonic bonding or hot melt bonding.

[0035] Please continue to refer to Fig. 2. The support element 51 has one side facing the first opening 21 and another side facing away from the first opening 21. The waterproof and air-permeable membrane 52 can be arranged on the side of the support element 51 facing the first opening 21. By arranging the waterproof and air-permeable membrane 52 on the side of the support element 51 facing the first opening 21, liquid substances are blocked on the side of the membrane 52 facing the first opening 21 due to the waterproof effect of the membrane 52, thereby reducing the likelihood of liquid substances coming into contact with the support element 51 and increasing the service life of the support element 51.

[0036] The waterproof and air-permeable membrane 52 can also be arranged on the opposite side of the support element 51, away from the first opening 21. Since the support element 51 possesses a certain structural rigidity, arranging the waterproof and air-permeable membrane 52 on the side opposite the first opening 21 effectively prevents the user's fingers from coming into direct contact with the waterproof and air-permeable membrane 52 when cleaning the vacuum massage structure 100. This reduces the likelihood of external forces exerted by the fingers acting directly on the waterproof and air-permeable membrane 52, thus increasing the service life of the waterproof and air-permeable assembly 50.

[0037] In this embodiment, the provision of the watertight and air-permeable assembly 50 in the first airflow channel 40, comprising the support element 51 and the watertight and air-permeable membrane 52, achieves, through the air permeability of the support element 51 and the watertight and air-permeable properties of the membrane 52, that the assembly 50 blocks liquid substances in the first airflow channel 40 while simultaneously allowing gas to pass through. Since the support element 51 is connected to the inner wall of the first airflow channel 40 and the membrane 52 is arranged on the support element 51, the membrane 52 is well supported by the support element 51, which increases the tensile strength of the assembly 50. Due to this increased tensile strength, the assembly 50 is not easily damaged by the forces of the airflow during operation under negative pressure.Since the assembly 50 is both waterproof and air-permeable, it can ensure stable operation under negative pressure. During use of the negative pressure massage structure 100, the negative pressure generating assembly 10 creates a negative pressure at the first opening 21 via the first airflow channel 40, thereby drawing in the skin of the area being massaged and producing a suction-like massage effect. The negative pressure generating assembly 10 draws liquid substances and gas together into the first airflow channel 40. Because the waterproof and air-permeable assembly 50 blocks liquid substances, they do not enter parts of the first airflow channel 40 or pass through it into the negative pressure generating assembly 10. This reduces the likelihood of hygienic dead spots or short circuits in the negative pressure generating assembly 10 and thus increases the reliability of the negative pressure massage structure 100.

[0038] In some embodiments, see further below. Fig. 2 and Fig. 4, the first chamber 20 has a first end 201 and a second end 202, the first end 201 being located near the first opening 21 and the second end 202 being located near the first connecting channel 30. The watertight and air-permeable assembly 50 is arranged in the first chamber 20 and is located between the first end 201 and the second end 202.

[0039] In this embodiment, the corner areas at the second end 202 of the first chamber 20, far from the first opening 21, as well as the interior of the first connecting channel 30, are relatively narrow spaces. If liquid substances are drawn into these narrow spaces, hygienic dead zones that are difficult to clean can easily form. By arranging the watertight and air-permeable assembly 50 in the first chamber 20 between the first end 201 and the second end 202, the assembly 50 can effectively prevent liquid substances from entering the narrow spaces (e.g., corner areas at the second end 202 and the interior of the first connecting channel 30). This reduces the likelihood of hygienic dead zones forming, improves the hygiene of the vacuum massage structure 100, and further increases its reliability.

[0040] In some embodiments, see further below. Fig. 2 to Fig. 5, the vacuum generation assembly 10 includes a vacuum pump.

[0041] Since a vacuum pump can realize the vacuum function in a small installation space, the design of the vacuum generation assembly 10 as a vacuum pump fulfills the design requirements of the vacuum massage structure 100.

[0042] In some embodiments, see Fig. 8, the waterproof and air-permeable membrane 52 is coated with a hydrophobic coating 70.

[0043] The hydrophobic coating 70 can be arranged by bonding it onto the waterproof and air-permeable membrane 52, whereby the bonding can be ultrasonic bonding, hot melt bonding or gluing.

[0044] In this embodiment, the hydrophobic coating 70 on the membrane 52 allows the "lotus effect" of the hydrophobic coating 70 to be utilized, so that liquid substances do not spread on the surface of the coating 70, but instead form small water droplets and roll on the surface. Under the influence of gravity, the liquid substances can thus be more easily drained from the first opening 21.

[0045] In some embodiments, the waterproof and air-permeable membrane 52 is one or more of the following membranes: an expanded polytetrafluoroethylene (ePTFE) membrane, a thermoplastic polyurethane (TPU) membrane, a polyethylene membrane, an acrylic membrane, a polypropylene membrane, a polyethersulfone membrane, a polyethylene terephthalate membrane, and a polyvinylidene fluoride membrane.

[0046] The waterproof and air-permeable membrane 52 can be an oleophobically modified ePTFE membrane. Oleophobic modification is a process for optimizing the surface properties of the ePTFE membrane, in which its surface energy is lowered by physical or chemical methods to improve the repellency of oily substances.

[0047] The surface of the ePTFE membrane can be coated with a fluorine compound to achieve the effect of oleophobic modification.

[0048] The oleophobically modified ePTFE membrane possesses both hydrophobic and oleophobic properties, meaning it blocks moisture and repels oily substances such as essential oils and massage creams. This prevents oily residues from accumulating on the membrane surface and clogging the micropores, thus extending the membrane's effective lifespan. The oleophobically modified ePTFE membrane meets medical standards, is non-toxic, hypoallergenic, and does not cause adverse reactions upon prolonged contact with human tissue, reducing the risk associated with long-term use. The thickness of the oleophobically modified ePTFE membrane can be as low as 0.02 mm, allowing for integration into small massage device cavities and offering a wide range of applications.

[0049] In this embodiment, the membrane materials mentioned (ePTFE, TPU, PE, acrylic, PP, PES, PET, PVDF) exhibit good waterproofness, air permeability, flexibility and chemical stability, so that the waterproof and air-permeable membrane 52 has good waterproof and air-permeable properties.

[0050] In some embodiments, see Fig. 9 to Fig. 12, a quick-release assembly 80 is also provided, wherein the support element 51 is detachably connected to the inner wall of the first airflow channel 40 via the quick-release assembly 80.

[0051] The support element 51 can be connected to the inner wall of the first connecting channel 30 via the quick-release assembly 80. The support element 51 can also be connected to the inner wall of the first chamber 20 via the quick-release assembly 80.

[0052] The connection of the support element 51 to the inner wall of the first airflow duct 40 via the quick-release assembly 80 can be a detachable connection, e.g., a threaded connection or a snap-fit ​​connection. The detachable connection facilitates the replacement of the watertight and air-permeable assembly 50 for the user.

[0053] In this embodiment, the detachable connection of the support element 51 to the inner wall of the first airflow channel 40 by means of the quick-release assembly 80 ensures that the support element 51 is more firmly connected to the inner wall during assembly. This allows the support element 51 to withstand external forces and prevents it from easily detaching due to vibrations, tension, or other external factors, thus increasing the tensile strength of the assembly 50. During disassembly, the support element 51 can be quickly removed from the inner wall, enabling rapid replacement.

[0054] In some embodiments, see further below. Fig. 9 and Fig. 10, the quick-release assembly 80 comprises a first threaded section 81 and a second threaded section 82, which are in thread engagement. The first threaded section 81 is arranged circumferentially on the outer wall of the support element 51, and the second threaded section 82 is arranged circumferentially on the inner wall of the first airflow channel 40.

[0055] The first thread section 81 can be an external thread or an internal thread. The second thread section 82 can be an internal thread or an external thread.

[0056] In this embodiment, the support element 51 is secured by the threaded engagement between the first threaded section 81 on the support element 51 and the second threaded section 82 in the first airflow channel 40. This makes the connection even stronger, so that the support element 51 better withstands external forces, is less likely to loosen, and the tensile strength of the assembly 50 is further increased. At the same time, the threaded engagement allows for quick disassembly.

[0057] In some embodiments, see further below. Fig. 11 and Fig. 12, the quick-release assembly 80 comprises a first locking section 83 and a second locking section 84, which are engaged in a locking position. The first locking section 83 is arranged circumferentially on the outer wall of the support element 51, and the second locking section 84 is arranged circumferentially on the inner wall of the first airflow channel 40.

[0058] The first detent section 83 can be a detent groove or a detent hook. The second detent section 84 can be a detent hook or a detent groove.

[0059] In this embodiment, the support element 51 is fixed by the locking engagement between the first locking section 83 and the second locking section 84. This also increases the strength of the connection and the tensile strength of the assembly 50 and enables quick disassembly.

[0060] In some embodiments, see Fig. 13, the first chamber 20 has a first end 201 and a second end 202, with the first end 201 being located near the first opening 21 and the second end 202 being located near the first connecting channel 30. The dimension of the first chamber 20 gradually decreases from the first end 201 to the second end 202.

[0061] The cross-sectional shape of the first chamber 20 can be rectangular or circular. In embodiments where the cross-section is circular, the radius of the first chamber 20 can gradually decrease from the first end 201 to the second end 202.

[0062] In this embodiment, the interior of the first chamber 20 is conical due to its tapered dimensions. As gas enters the first chamber 20 and flows from the first end 201 to the second end 202, the cross-sectional area of ​​the flow decreases continuously, thereby increasing the flow velocity of the gas in the first chamber 20. This enhances the suction effect of the first chamber 20 and improves the massage effect.

[0063] In some embodiments, see Fig. 14, a spray assembly 90 is further provided. The first chamber 20 has a first end 201 and a second end 202, the first end 201 being located near the first opening 21 and the second end 202 being located near the first connecting channel 30. The spray assembly 90 is arranged at the first end 201.

[0064] The atomization assembly 90 can be a piezoelectric ceramic plate that directly contacts liquid substances and generates a cavitation effect through high-frequency vibration from 1.7 MHz to 3.5 MHz, thereby immediately breaking down water molecules into micrometer-sized water mist.

[0065] In this embodiment, the atomizing assembly 90 can atomize liquid substances at its first end 201. This breaks up any remaining liquid substances on the inner wall of the first chamber 20 into a large number of tiny droplets, suspending them in the gas to form a gas-liquid two-phase flow. This reduces the likelihood of liquid substances remaining on the inner wall of the first chamber 20.

[0066] In some embodiments, see Fig. 15 and Fig. 16, furthermore a protective element 110 is provided, which is arranged in the first airflow channel 40 and is located between the first opening 21 and the waterproof and air-permeable assembly 50.

[0067] The protective element 110 can be arranged in the first connecting channel 30 or in the first chamber 20.

[0068] The protective element 110 can comprise a first protective element 111 and a second protective element 112. There can be one or more first protective elements 111 and second protective elements 112.

[0069] In embodiments with one protective element each, the two ends of the first protective element 111 and the second protective element 112 are each connected to the inner wall of the first connecting channel 30 or the first chamber 20, intersecting and forming a cross structure.

[0070] In embodiments with multiple protective elements, these are each connected to the inner walls and cross over each other to form a network structure.

[0071] Due to its cross or mesh structure, the protective element 110 is air-permeable.

[0072] In this embodiment, the protective element 110 effectively prevents the user's fingers from coming into direct contact with the waterproof and air-permeable assembly 50 during cleaning, thus increasing the service life of the assembly 50.

[0073] In some embodiments, the first opening 21 is made of a flexible material, wherein the flexible material is one or more of the following materials: TPE, POE, PVC, silicone or liquid silicone.

[0074] In this embodiment, materials such as TPE, POE, PVC, silicone, or liquid silicone have a low Shore hardness and therefore a low modulus of elasticity. This makes the first opening 21 softer and more easily deformable. This allows the first chamber 20 to better adapt to the shape of the area being massaged during use, so that the first opening 21 fits more snugly against the skin, further improving the massage effect.

[0075] In some embodiments, see Fig. 17, furthermore a first elastic element 120 is provided, which is received in the first connecting channel 30.

[0076] The first elastic element 120 can be a spring or a metal spring leaf. In embodiments where the first elastic element 120 is a spring, the length of the spring can be equal to the length of the first connecting channel 30.

[0077] In this embodiment, the deformability of the first connecting channel 30 is limited, so that after bending due to external force, it may not return to its original state, which reduces the flow area and impairs the suction effect. The first elastic element 120 inside increases the deformability, allowing the channel to return to its original state after bending, thus reducing the influence of cross-sectional changes on the massage effect.

[0078] In some embodiments, see Fig. 18, a control valve 130 is also provided, which is arranged on the first connecting channel 30 and controls its opening or closing.

[0079] In embodiments with control valve 130, the vacuum massage structure 100 can include a circuit control assembly that is electrically connected to the control valve 130 and the vacuum generation assembly 10 and controls their opening or closing.

[0080] In this embodiment, the control valve 130 can rapidly open and close the first connecting channel 30, creating a pulsed vacuum in the first chamber 20. This causes the first opening 21 to perform alternating suction, release, re-suction, and re-release actions on the area to be massaged. This effectively activates the proprioceptors of the muscles, promotes blood circulation, and improves relaxation. Furthermore, the control valve 130 can regulate the duration of the vacuum suction to adapt the intensity to different massage areas.

[0081] In some embodiments, see Fig. 19, a second connecting line 140 is also provided. One end of the second connecting line 140 communicates with the vacuum generating assembly 10, the other end with the environment of the vacuum massage structure 100. When the control valve 130 closes the first connecting channel 30, the vacuum generating assembly 10 draws in air through the second connecting line 140.

[0082] The first housing 60 may have a first ventilation opening that connects the inside and outside of the structure, with the other end of the second connecting line 140 being able to communicate with this opening.

[0083] The second connecting line 140 can be a hose or flexible pipe, the ends of which can be detachably connected.

[0084] In this embodiment, the second connecting line 140 ensures that the vacuum generating assembly 10 immediately draws in air from the outside when the control valve 130 closes the first connecting channel 30. This allows the vacuum generating assembly 10 to operate continuously and maintain a stable pressure. Without the second connecting line 140, closing the first connecting channel 30 would cause a sudden pressure surge, and upon reopening, the suction force could drop or rise abruptly, potentially leading to strong suction or pulling on the skin. The second connecting line 140 balances the pressure and prevents sudden changes in suction force during switching, thus increasing user comfort.

[0085] In some embodiments, see Fig. 20, furthermore a second elastic element 150 is provided, which is included in the second connecting line 140.

[0086] The second elastic element 150 can be a spring or a metal leaf spring. In embodiments where the second elastic element 150 is a spring, the length of the spring can be equal to the length of the second connecting line 140.

[0087] In this embodiment, the second elastic element 150 increases the deformability of the second connecting line 140, so that it can return to its original state after bending, which reduces the influence of cross-sectional changes on the massage effect.

[0088] In some embodiments, see Fig. 21, the present application provides a massage device 1000 comprising a first massage structure 200 and the vacuum massage structure 100 according to one of the embodiments mentioned above, wherein the first massage structure 200 is connected to the vacuum massage structure 100.

[0089] The first massage structure 200 may also include a second housing 202, which may or may not be part of the first housing 60. The second housing 202 may be made of a flexible material such as silicone or liquid silicone.

[0090] The surface of the first massage structure 200 can be provided with first massage sections 201, which may include several first projections or uninterrupted second projections.

[0091] In some embodiments, see further below. Fig. 21, a connecting element 210 is further provided, wherein the first massage structure 200 is flexibly connected to the vacuum massage structure 100 via the connecting element 210.

[0092] The connecting element 210 can be a plastically deformable plastic part.

[0093] In this embodiment, the connecting element 210 allows the first massage structure 200 to be movable relative to the vacuum massage structure 100. By rotating the first massage structure 200, its angle can be adjusted so that both structures can simultaneously massage two different areas, further improving the massage effect.

[0094] In some embodiments, see Fig. 22, a vibration assembly 220 is also provided, which is arranged in the first massage structure 200 and drives it to vibrate.

[0095] The vibration assembly 220 can be a micro vibration motor.

[0096] In this embodiment, the vibration assembly 220 provides a vibration massage, which further improves the massage effect.

[0097] In some embodiments, see Fig.23, a heating assembly 230 is also provided, which is arranged in the first massage structure 200 and is in heat exchange with it.

[0098] The heating assembly 230 can be a heating element.

[0099] In this embodiment, the heating assembly 230 enables the simulation of a temperature environment during the massage, which further improves the massage effect.

[0100] It is obvious to the person skilled in the art that the embodiments mentioned above serve only to illustrate the technical solutions of the present application and are not intended to limit them. All modifications, equivalent substitutions, and improvements made in the spirit and principle of the present application are intended to be included within the scope of protection of the present application.
