[0040] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0042] like Figure 1 as well as Figure 2 As shown, this application provides a massage device 10, including a flexible wear strap 100 and a massage device 200, the massage device 200 being fixed to the flexible wear strap 100. This facilitates the fixation of the massage device 200 to the user's body via the flexible wear strap 100.

[0043] The massage device 200 includes a negative pressure suction member 210, a support assembly 220, and a massage assembly 230. The negative pressure suction member 210 has a cavity 211 with a suction port 201. The support assembly 220 is disposed within the cavity 211 and fixedly connected to the negative pressure suction member 210. The massage assembly 230 is mounted on the support assembly 220. The massage assembly 230 includes a massage section 231 movably disposed within the cavity 211.

[0044] When in use, the massage device 10 is secured to the user's body via a flexible strap 100. Simultaneously, the negative pressure suction member 210 generates suction, further securing the massage component 230 to the area to be massaged 231. The massage component 230 is then activated, vibrating and massaging the area to be massaged 231 to alleviate discomfort. During this process, the negative pressure suction member 210, in conjunction with the flexible strap 100, reliably secures the massage device 200 to the user's body. Furthermore, the negative pressure suction generated by the massage component 231 during vibration ensures that the massage component 231 remains aligned with the area to be massaged 231, preventing movement and ensuring a consistent massage effect, thereby enhancing the overall massage performance of the massage device 10.

[0045] It should be noted that the flexible wearable device 100 can be implemented in various ways, as long as it can be strapped to the user's waist, back, shoulders, neck, hips, and limbs. For example, in some embodiments, the flexible wearable device 100 includes a strap. Alternatively, in some embodiments, one end of the flexible wearable device 100 has a male Velcro strap, and the other end has a female Velcro strap. Alternatively, in some embodiments, one end of the flexible wearable device 100 has a locking part, and the other end has a buckle part that engages with the locking part. In other embodiments, the flexible wearable device 100 also has a belt, waistband, or other similar structures.

[0046] It should be noted that the negative pressure adsorption component 210 can be implemented in various ways, including manually generating adsorption force. For example, negative pressure adsorption force can be generated by squeezing the elastic material. Alternatively, the negative pressure adsorption component 210 has a canister with a piercing design, and the canister can generate adsorption force by rotating the suction rod. It can also be connected to a negative pressure generator 300 to generate adsorption force in the cavity 211.

[0047] like Figure 2 As shown, in some embodiments, the negative pressure adsorption member 210 is elastic, enabling the cavity 211 to generate adsorption force. Thus, by squeezing the negative pressure adsorption member 210, elastic deformation occurs, reducing the volume of the cavity 211. After the negative pressure adsorption member 210 is tightly fitted to the skin, releasing it allows the negative pressure adsorption member 210 to expand the volume of the cavity 211 under elastic restoring action, thereby generating negative pressure adsorption force within the cavity 211.

[0048] like Figure 3 as well as Figure 5 As shown, in some embodiments, the negative pressure adsorption component 210 is provided with a vent 202, and the massage device 10 also includes a negative pressure generator 300, which is fixed to the flexible wearable 100 and has an air intake portion communicating with the vent 202. Thus, the negative pressure generator 300 can draw away the gas in the cavity 211 through the vent 202, so that the cavity 211 can generate an adsorption force that adheres and fixes to the user's body.

[0049] like Figure 2 as well as Figure 3 As shown, in some embodiments, the massage devices 200 include at least two and are spaced apart on the flexible wear 100. Thus, by using at least two massage devices 200, multiple parts of the user's body can be massaged simultaneously, which helps to improve the massage efficiency of the massage device 10.

[0050] like Figure 4 As shown, in some embodiments, the flexible wearer 100 includes a proximal surface 110 and a distal surface 120 disposed opposite to the proximal surface 110. The massage device 200 and the negative pressure generator 300 are disposed on the proximal surface 110. In this way, the massage device 200 and the negative pressure generator 300 are integrated on the proximal surface 110, making the distal surface 120 flatter and more convenient for users to massage their lower back while lying down.

[0051] In other embodiments, the negative pressure generator 300 is positioned on the distal skin surface 120. This arrangement of the negative pressure generator 300 does not interfere with the massage device 200, allowing the massage device 200 to better conform to the user's skin.

[0052] It should be understood that "skin-friendly side 110" should be interpreted broadly, usually referring to the side that is in contact with the user's skin.

[0053] like Figure 3 As shown, in some embodiments, the negative pressure generator 300 includes a negative pressure pump 310 and a pressure holding valve 320 connected to the negative pressure pump 310, with the suction section disposed at the pressure holding valve 320. Thus, the pressure holding valve 320 can improve the stability of the gas suction by the negative pressure pump 310, and can also continue to increase the suction force for the cavity 211 after the negative pressure pump 310 is powered off, ensuring that the negative pressure adsorption component 210 can reliably adhere to the user's body.

[0054] like Figure 3 As shown, in some embodiments, the suction section is connected to the vents 202 of at least two massage devices 200. Thus, the negative pressure generator 300 can provide a suction function for at least two massage devices 200, causing the cavities 211 of at least two negative pressure suction members 210 to generate suction force.

[0055] like Figure 3 As shown, in some embodiments, the massage device 10 also includes a vent pipe 400, one end of which is connected to the suction unit and the other end of which is connected to the vent hole 202. Thus, the vent pipe 400 allows for more flexible positioning of the negative pressure pump 310 and the massage device 200.

[0056] like Figure 3 As shown, in some embodiments, the negative pressure generator 300 further includes a pressure relief valve 340, the air inlet of the negative pressure pump 310 is connected to the pressure holding valve 320, and the air outlet of the negative pressure pump 310 is connected to the pressure relief valve 340.

[0057] In some embodiments, at least a portion of the ventilator 400 is embedded within the flexible band 100. This facilitates full utilization of the thickness of the flexible band 100 to secure the ventilator 400, preventing it from moving freely and separating from the vent 202 or the inhalation portion.

[0058] In some embodiments, the ventilation tube 400 corresponds one-to-one with the massage device 200.

[0059] like Figure 3 As shown, in some embodiments, the negative pressure generator 300 further includes a diversion valve 330, through which the air intake section is connected to one end of at least two air vents 400. Thus, the diversion valve 330 can draw air evenly, making the suction force generated by each negative pressure adsorption element 210 more uniform and improving the massage effect.

[0060] In conjunction with any embodiment of the above-described vent 202, such as Figure 5 as well as Figure 6 As shown, in some embodiments, the negative pressure adsorption component 210 includes a rigid cavity 212 with a cavity 211. The rigid cavity 212 has a vent 202 communicating with the negative pressure pump 310. The support component 220 is fixedly connected to the rigid cavity 212, and at least a portion of the support component 220 is spaced apart from the sidewall of the cavity 211. Thus, by utilizing the sufficient strength of the rigid cavity 212, the cavity 211 can generate a greater adsorption force, enabling the rigid cavity 212 to cooperate with the negative pressure generator 300 to provide cupping therapy. like Figure 5 as well as Figure 6 As shown, in some embodiments, the rigid cavity 212 is provided with a flange 203, the cross-section of which is arc-shaped. In this way, the flange 203 can increase the contact area between the rigid cavity 212 and the user's skin, making the rigid cavity 212 adhere more firmly to the user's skin.

[0061] like Figure 6As shown, in some embodiments, the support component 220 and the inner wall of the cavity 211 are spaced apart to form an annular channel 204, and the vent 202 communicates with the annular channel 204. In this way, the annular channel 204 can generate a negative pressure adsorption force, so that the support component 220 can be reliably fixed above the part to be massaged 231.

[0062] It should be noted that the massage component 230 can be implemented in various ways, including but not limited to a vibration motor, a telescopic presser (such as a telescopic motor used in fascia guns), a oscillating massager, a rotating massager, and so on.

[0063] like Figure 6 As shown, in some embodiments, the massage assembly 230 includes a vibration motor 232 capable of driving the massage section 231 to vibrate.

[0064] like Figure 6 As shown, in some embodiments, the support component 220 includes a protective frame 221, which is fixedly connected to the bottom of the negative pressure adsorption member 210 and forms a protective cavity 205 for the massage component 230. This improves the protective performance of the massage component and enhances the durability of the massage device.

[0065] It should be noted that there are various ways to achieve the "fixed connection" between the bottom of the protective frame 221 and the negative pressure adsorption component 210, including but not limited to adhesive fixing, snap-on fixing, screw fixing, etc.

[0066] In some embodiments, the protective frame 221 and the negative pressure adsorption component 210 are integrally formed and fixed. This helps to reduce assembly steps.

[0067] like Figure 6 As shown, in some embodiments, the massage device 200 further includes a deformable first pulse electrode 240, which is fixedly connected to the protective frame 221 and covers the protective cavity 205. The massage part 231 can press against the first pulse electrode 240. Thus, the massage device 200 can also provide pulse massage function through the first pulse electrode 240, further improving the massage effect of the massage device 10. When the massage part 231 vibrates, it can press against the first pulse electrode 240 to transmit the vibration to the user's body.

[0068] In addition, the first pulse electrode 240 has adhesive properties, which can further improve the fixation reliability of the massage device 200 to the user's body.

[0069] Optionally, the first pulse electrode 240 has a heating element. Thus, when the massage device 200 provides pulse massage via the first pulse electrode 240, it can also use the heating element for heat therapy to enhance the massage effect.

[0070] like Figure 6 As shown, in some embodiments, the massage device 200 further includes a first heating element 250, which is disposed between the first pulse electrode plate 240 and the massage part 231. Thus, the massage device 200 can also provide a heat therapy function through the first heating element 250, further enhancing the massage effect of the massage device 10.

[0071] like Figure 7 As shown, in some embodiments, the support assembly 220 further includes an elastic shield 222, which is fixedly connected to the protective frame 221 and covers the protective cavity 205. The massage unit 231 can press against the elastic shield 222. Thus, when the massage unit 231 is used for vibration, it can press against the elastic shield 222 to transmit the vibration to the user's body.

[0072] like Figure 7 As shown, in some embodiments, the massage device 200 further includes a second pulse electrode 260, which is fixed to the outer wall of the elastic shield 222 and positioned towards the suction port 201. Thus, the massage device 200 can also provide a pulse massage function through the second pulse electrode 260. In addition, the second pulse electrode 260 has adhesive properties, which can further improve the fixation reliability of the massage device 200 to the user's body.

[0073] like Figure 7 As shown, in some embodiments, the massage device 200 further includes a second heating element 270 disposed within the protective cavity 205, and the second heating element 270 is fixed to the elastic shielding member 222. Thus, the massage device 200 can also provide a heat therapy function through the second heating element 270, further enhancing the massage effect of the massage device 10.

[0074] In addition, the second pulse electrode and the second heating element are fixed on the elastic shielding element, which makes them easy to replace.
