Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.
[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a massage therapy device provided in an embodiment of the present invention. The massage therapy device includes a fascia ball 1.
[0022] The outer surface of the fascia ball 1 is provided with an elastic therapy layer 2, the inside of the elastic therapy layer 2 is provided with a support layer 3, and the inside of the support layer 3 forms a hollow cavity 4; the fascia ball 1 is provided with an injection hole 5 that communicates with the hollow cavity 4, and a removable plug 6 is installed on the injection hole 5; the injection hole 5 is used to inject a liquid medium 7 in a preset temperature range into the hollow cavity 4.
[0023] Specifically, the elastic therapy layer 2 can be made of rubber or silicone; the support layer 3 can be made of metal, such as a hollow metal sphere. The support layer 3 can also be made of high-strength fiber material with three-dimensional weaving. This three-dimensional weaving method allows the support layer 3 to have excellent mechanical properties in all directions, enabling it to withstand greater pressure without easily deforming. After the liquid medium 7 is injected into the hollow cavity 4, even when the fascia ball 1 is subjected to significant external pressure (such as the heavy pressure of the user's body weight), the support layer 3 can still maintain the basic shape of the fascia ball 1, ensuring that the liquid medium 7 is evenly distributed within the cavity and that heat transfer is stable. At the same time, the high-strength fiber material has a lighter weight, which will not excessively increase the overall weight of the fascia ball 1, ensuring ease of use and flexibility.
[0024] The liquid medium 7 can be hot water. To facilitate the filling of the fascia ball 1 with hot water, an vent hole communicating with the hollow cavity 4 can be provided on the fascia ball 1. The vent hole can be a small hole, the diameter of which is determined according to the size of the fascia ball 1, for example, 0.2-0.5 mm. For a fascia ball 1 with a diameter of 10 cm, the vent hole diameter can be set to 0.3 mm. Alternatively, a vent hole structure with a one-way valve can be used. When hot water is filled, air can be smoothly discharged from the inside of the fascia ball 1, and when the internal pressure of the fascia ball 1 is balanced with the external pressure, the one-way valve automatically closes to prevent hot water leakage.
[0025] For example, please refer to Figure 2 , Figure 2 This is a schematic diagram of the support layer 3. The support layer 3 is a skeleton structure, and the area of each hollow part 18 of the skeleton structure is smaller than a preset value. The preset value can be determined based on the strength requirements of the support layer 3. The skeleton structure can withstand external pressure during the use of the fascia ball 1 while maintaining its own structural integrity, and will not easily break or deform. It can be understood that the skeleton structure allows the liquid medium 7 to directly contact the elastic therapy layer 2. When the liquid medium 7 is hot water, it can conduct heat more easily, reducing the heat insulation inside the support layer 3.
[0026] To improve the overall structural strength of the support layer 3 of the skeleton structure, injection holes 5 are opened at the connection nodes of the skeleton structure. The connection nodes of the skeleton structure are the places where multiple skeletons intersect. These parts are relatively more stable in terms of structural mechanics and have higher strength and load-bearing capacity.
[0027] During long-term use of the fascia ball 1, the supporting layer 3 and the elastic therapy layer 2 may experience relative displacement or separation due to frequent compression, friction, and temperature changes. Therefore, in one specific embodiment, the elastic therapy layer 2 has a first protrusion 8 inside, which is used to embed the hollow portion 18 of the skeleton structure. The shape, size, and distribution of the first protrusion 8 are adapted to the hollow portion 18 of the skeleton structure. The first protrusion 8 can be columnar, conical, or other suitable shapes. After the first protrusion 8 is embedded in the hollow portion 18, it enhances the connection stability between the supporting layer 3 and the elastic therapy layer 2. Under various usage conditions of the fascia ball 1, whether it is normal rolling massage, local compression, or thermal expansion and contraction caused by temperature changes, both can maintain a tight bond. This ensures the structural integrity of the fascia ball 1, enabling it to continuously and stably perform its massage therapy function and extending the product's service life.
[0028] In practical applications, relying solely on injecting liquid medium 7 (such as hot water) into the fascia ball 1 will cause its temperature to gradually decrease over time, making it difficult to maintain a suitable therapeutic temperature range for an extended period. Therefore, in one specific embodiment, a metal inner liner 10 is provided within the hollow cavity 4, and the metal inner liner 10 is filled with a thermoregulatory phase change medium 11. The metal inner liner 10 can be installed within the hollow cavity 4 via multiple connectors 12. The metal inner liner 10 can be made of a material with good thermal conductivity, such as copper or aluminum. Filling the metal inner liner 10 with a thermoregulatory phase change medium 11 (PCM) can balance the temperature of the fascia ball 1. A suitable phase change medium 11 with a phase change temperature can be selected based on the usage requirements of the fascia ball 1. For example, if it is desired that the fascia ball 1 can maintain a temperature range of approximately 40-45°C for an extended period, a thermoregulatory phase change medium 11 with a phase change temperature of approximately 42°C can be selected. When the temperature of the fascia ball 1 rises, the heat-regulating phase change medium 11 absorbs heat and undergoes a phase change, thus delaying the temperature rise. When the temperature decreases, the heat-regulating phase change medium 11 releases heat to maintain a stable temperature. The heat-regulating phase change medium 11 can be sodium sulfate decahydrate, stearic acid, etc. The heat-regulating phase change medium 11 can prolong the duration of the fascia ball 1 in the preset temperature range, thus improving the ease of use.
[0029] Please continue reading. Figure 1 Different shapes and sizes of massage bumps or textures can be designed on the outer surface of the elastic therapy layer 2, serving as the second raised part 9. Their height and spacing are designed based on usage needs. When the fascia ball 1 rolls on the muscle, the bumps can precisely stimulate muscle nodules and trigger points, similar to the finger pressure of a professional rehabilitation therapist, enhancing the targeting and depth of the massage. Alternatively, a spiral texture can be used, producing a massage-like effect during rolling, promoting muscle relaxation and stretching. These massage bumps and textures can be customized according to the muscle characteristics and massage needs of different parts of the body. For example, larger, harder bumps can be used to stimulate acupoints on the soles of the feet during foot massage, while finer, softer textures can be used during neck massage to avoid overstimulation.
[0030] For further information, please refer to [link / reference]. Figure 1 A temperature indicator 13 is embedded in the outer surface of the fascia ball 1. The temperature indicator 13 can be a temperature-sensing paper encapsulated on the outer surface of the fascia ball 1, or it can be a liquid crystal temperature indicator bar. The surface temperature of the fascia ball 1 can be determined based on the temperature displayed by the temperature indicator 13, helping the user adjust the massage method or change the liquid medium 7 according to the temperature, ensuring a good thermotherapy effect with each use. At the same time, the temperature indicator 13 improves safety, allowing users to avoid using the fascia ball 1 at excessively high temperatures and reducing the risk of burns.
[0031] If the injection hole 5 is not properly sealed, the liquid medium 7 (such as hot water, oil, etc.) inside the hollow cavity 4 can easily leak out during the use of the fascia ball 1, which will not only wet the surrounding environment but also soil the user's clothing. Therefore, in one specific embodiment, the injection hole 5 and the plug 6 are connected by a threaded structure. Please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic diagram of the connection structure between the injection hole 5 and the plug 6. A sealing element 19 can be installed on the plug 6.
[0032] Those skilled in the art will understand that achieving heat therapy or insulation by injecting hot water into a closed container is common knowledge. For example, everyday hot water bottles achieve a continuous heat release effect by injecting hot water into a sealed cavity and sealing it with a plug. This type of structure is widely used in medical heat therapy, rehabilitation therapy, and daily health care, and mature technologies have been developed for its sealing structure, hygiene control, and reusability. Therefore, the technique of injecting hot water into the fascia ball through an injection hole to achieve heating in this application is a reasonable application of existing mature technology. After use, the liquid medium can be discharged through the injection hole, and the hollow cavity can be rinsed with clean water or disinfectant, thus achieving reusability and hygiene assurance.
[0033] The inner wall of the injection hole 5 is machined with internal threads, and correspondingly, the outer wall of the plug 6 is provided with matching external threads. The thread pitch, tooth profile, and other parameters can be reasonably determined based on factors such as the size of the injection hole 5 and the overall dimensions of the fascia ball 1. The threaded connection allows for a tight fit between the injection hole 5 and the plug 6, forming multiple lines of sealing through the thread engagement. When the plug 6 is screwed into the injection hole 5, the tiny gaps between the threads are filled by the surface tension of the liquid medium 7 and the rubber seals 19, effectively preventing leakage of the liquid medium 7. Even under significant external force, changes in internal pressure, or prolonged use, the fascia ball 1 maintains a good seal, ensuring stable storage of the liquid medium 7 inside the fascia ball 1.
[0034] In practical applications, when directly injecting liquid medium 7 into the injection hole 5 of the fascia ball 1, it is often necessary to hold the fascia ball 1 with one hand and the container holding the liquid medium 7 with the other. This operation is cumbersome and makes it difficult to ensure a smooth and precise injection process. Especially when the injection hole 5 is relatively small, problems such as liquid spillage and difficulty in controlling the injection speed can easily occur, affecting injection efficiency and user experience. Therefore, please refer to... Figure 4 In one specific embodiment, the physiotherapy device further includes an infusion stand 14.
[0035] The infusion stand 14 is equipped with a positioning seat 15 for supporting the fascia ball 1. The top of the positioning seat 15 is equipped with an injection hopper 16 that connects to the injection hole 5. The infusion stand 14, as a supporting structure, has good stability and can be made of metal or plastic. The positioning seat 15 is set on the infusion stand 14, and its shape and size are customized according to the shape of the fascia ball 1. For example, if the fascia ball 1 is spherical, the positioning seat 15 can be designed as a hemispherical groove that fits into the lower half of the fascia ball 1, or a seat with a circumferential structure, which can accurately fix the fascia ball 1 in the corresponding position, restrict its movement and shaking during the injection process, and ensure that the injection hole 5 is always aligned with the injection device, facilitating subsequent injection operations. The injection hopper 16 is located on top of the positioning seat 15. Its shape is a funnel, wider at the top and narrower at the bottom. The larger opening end is convenient for receiving the liquid medium 7, such as hot water poured from the spout of an ordinary kettle. The lower part of the injection hopper 16 is connected to the injection hole 5 of the fascia ball 1 via a pipe or direct connection.
[0036] like Figure 4 As shown, the injection hopper 16 can be configured as a flip-up structure. The arrow in the figure indicates the flipping direction of the injection hopper 16. This flip-up structure facilitates the placement of the fascia ball 1 for injection. The fascia ball 1 is fixed by the positioning seat 15 on the infusion stand 14, eliminating the need for the user to hold the fascia ball 1 during injection. The user can more easily operate the injection container and control the injection speed with both hands. The accurate connection between the injection hopper 16 and the injection hole 5 allows the liquid medium 7 to flow precisely into the fascia ball 1, avoiding spillage of the liquid medium 7 and inaccurate injection, thus improving the efficiency and convenience of injection.
[0037] Furthermore, the pouring stand 14 is provided with a handhold 17 for easy gripping. A handle-like structure can be installed on one side of the pouring stand 14. The shape of the handle conforms to the gripping action of the human hand, ensuring that the stand can maintain balance and facilitate the application of force when moving or operating the pouring stand 14 while holding the handhold 17.
