Description

Technical Field

[0001] This utility model relates to the field of massage therapy equipment technology, and in particular to an air wave pressure therapy device. Background Technology

[0002] Air wave pressure therapy device, also known as air wave massager, is a device that uses air pressure fluctuations for massage and is widely used in medical rehabilitation and daily health care.

[0003] Chinese utility model patent CN217366479U discloses an adjustable-size air wave massage hand and leg sleeve, belonging to the field of air wave massage instruments. This utility model includes zippers one, two, three, and four, and the hand and leg sleeve body. The hand and leg sleeve body adopts a multi-segment airbag structure. Zippers one, two, three, and four are respectively located at corresponding positions on the hand and leg sleeve body. Different combinations of zippers one, two, three, and four allow for adjustable size of the hand and leg sleeve body.

[0004] Existing airwave massage therapy devices mostly use a leg sleeve design that covers the entire foot. The leg sleeve is typically formed by multiple large, flexible airbags arranged together. However, this leg sleeve design, with its excessive number and size of flexible airbags, increases inflation time, which is detrimental to achieving a better massage effect. Furthermore, the leg sleeve design is inconvenient for users to wear. Utility Model Content

[0005] To address the technical problems existing in the prior art, the purpose of this utility model is to provide an air wave pressure therapy device that employs a massage belt design. This belt has a flexible body and several air bladders, with a relatively small number of air bladders and a small overall size. This reduces inflation time, allowing the air pump to complete inflation and deflation more quickly, achieving a more ideal massage effect.

[0006] The objective of this utility model is achieved through the following technical solution:

[0037] To facilitate understanding of this utility model, the technical solutions and advantages of the utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Any mechanisms or methods not elaborated in this utility model can be referred to in the prior art. The specific structure and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0038] like Figure 1-7 As shown in the figure, this embodiment provides a preferred structure for an air wave pressure therapy device.

[0039] like Figure 1 As shown, the air wave pressure therapy device of this utility model includes a control device 100 and a massage belt 200. The control device is equipped with a circuit board 110, an air pump 120, and multiple solenoid valves 130 connected to each other. The air pump 120 is connected to the solenoid valves 130. The massage belt 200 includes a flexible belt body 210 and a number of airbags 220 disposed within the flexible belt body 210. The two ends of the flexible belt body 210 are equipped with Velcro. The flexible belt body is configured to be tied to the legs or abdomen of the human body. Each airbag 220 is connected to a corresponding solenoid valve 130 through a silicone tube. The air pump 120 is used to inflate and deflate the airbags 220.

[0040] like Figure 1 As shown, the control device of this utility model includes a housing, a physical button assembly disposed on the housing, a display screen, a power interface, a massage belt interface, etc., as well as a circuit board, an air pump, and multiple solenoid valves disposed on the inner wall of the housing.

[0041] Specifically, circuit board 110 is connected to air pump 120 and solenoid valve 130. As the control core of the entire device, the circuit board integrates key components such as microprocessor, sensor interface, and power management module. The microprocessor is responsible for receiving input commands from the user via physical buttons (such as massage mode, intensity, time, etc.) and controlling the operation of air pump and solenoid valve through preset programs to achieve different massage effects.

[0042] like Figure 4 and Figure 5 As shown, the circuit board includes an air pump / solenoid valve drive circuit. The air pump is a key component that provides power for inflating the airbags. It is connected to multiple solenoid valves via silicone tubing. The solenoid valves control the flow and direction of airflow, with each solenoid valve connected to an airbag via a silicone tubing. When a solenoid valve opens, compressed air from the air pump enters the airbag, inflating it; when the solenoid valve closes, the air inside the airbag is expelled, deflating it. By precisely controlling the opening and closing of the solenoid valves, the airbags can be inflated and deflated in an orderly manner, thus producing a massage effect.

[0043] In a preferred embodiment, the control device further includes a plurality of pressure sensors connected to the circuit board 110, the pressure sensors being used to acquire pressure values ​​within the air chamber of the airbag. Figure 6 As shown, this is the pressure acquisition and amplification circuit on the circuit board. The pressure sensor collects the pressure data inside the airbag, which is then amplified and converted by an AD converter before being sent to the microprocessor, MCU chip, or single-chip microcomputer on the circuit board for feedback control of the inflation status and overpressure protection. The pressure sensor used is the US9111-006S manufactured by Unisense Corporation of Taiwan.

[0044] This invention employs a massage belt design, which includes a flexible belt body 210 and several air bladders 220. The number of air bladders is relatively small, and their volume is also small. This reduces inflation time, allowing the air pump to complete the inflation and deflation operations more quickly, achieving a more ideal massage effect.

[0045] In one specific implementation, the number of airbags 220 is 2 to 4. The airbags 220 are the core components of the massage belt 200, distributed within the flexible belt body. The number of airbags 220 generally corresponds to key areas of the human body, such as the muscle groups of the legs, to achieve the best massage effect. Compared with traditional designs, the volume and number of airbags in this invention are smaller.

[0046] In one specific embodiment, the flexible band 210 is preferably made of soft, comfortable fabric that conforms to the body's legs or abdomen. Both ends of the flexible band are equipped with Velcro, allowing the user to flexibly adjust the tightness of the band according to their leg or abdominal size, ensuring the massage band is securely fixed to the body. Each airbag is connected to a solenoid valve via a silicone tube. The silicone tube has good flexibility and airtightness, ensuring smooth airflow. This one-to-one connection method allows each airbag to be independently controlled, achieving different massage effects according to different massage needs.

[0047] In a specific implementation, such as Figure 3 and Figure 7 As shown, the airbag 220 has a cylindrical structure. The outer wall of the airbag 220 has multiple pleats 221, which are distributed sequentially along the axis of the airbag. The pleats 221 are annular pleats. The cylindrical end of the airbag bulges when inflated, and the end comes into contact with the human body during inflation, applying pressure and massage.

[0048] Understandably, the outer wall of the airbag 220 has multiple annular pleats, which are distributed sequentially along the axis of the airbag. The pleats 221 are designed similarly to the pleats of an accordion, allowing them to freely expand and contract during inflation and deflation. The columnar end of the airbag bulges out during inflation, forming a contact surface with a certain degree of elasticity and pressure.

[0049] In practice, the airbag is relatively small in size, with a cylindrical diameter of 30mm or 40mm and a height of 30-35mm.

[0050] In a preferred embodiment, a plurality of constraint rings 222 are fitted onto the outer peripheral wall of the airbag 220, and the constraint rings 222 are disposed between two adjacent pleats 221; the outer diameter of the constraint rings 222 is smaller than the outer diameter of the pleats 221 of the airbag 220, and the constraint rings are configured to constrain the radial expansion of the airbag.

[0051] Understandably, the constraint ring 222 can effectively control the expansion profile of the airbag during inflation by limiting its radial expansion. The massage thrust primarily comes from axial expansion; therefore, using a constraint rope to restrict the radial expansion of the airbag to achieve a better massage effect increases the airbag's thrust and axial elongation.

[0052] In one specific implementation, the restraint ring 222 is a nylon rope or aramid rope tied to the airbag. Nylon rope has good elasticity and abrasion resistance, which can effectively restrain the radial expansion of the airbag. Aramid rope is a high-performance fiber rope with advantages such as high strength, high modulus, high temperature resistance, cut resistance, and chemical corrosion resistance.

[0053] Regarding the airbag installation method, the flexible belt 210 is equipped with a mounting base 211 adapted to the airbag 220, and the mounting base 211 has multiple buckles. The end of the airbag 220 is provided with a connector 223, which has buckle holes that can be fitted with the buckles. The airbag is detachably fastened to the mounting base of the flexible belt through the connector. The airbag installation method adopts a detachable design, enabling quick installation and removal through the mounting base on the flexible belt and the connector at the end of the airbag. This design not only improves the ease of equipment maintenance.

[0054] Specifically, the connector is a circular disc structure with multiple snap holes. The connector is fixed to one end of the airbag using adhesive. It is made of the same material as the airbag.

[0055] In one specific implementation, the flexible belt 210 adopts a composite fabric structure, comprising an outer fabric, an inner lining, and an inner fabric sewn together as one piece, with the inner fabric used for contact with the human body. The inner lining is fixed to the outer fabric, the mounting base is fixed to the inner lining, and the airbag is located between the inner lining and the inner fabric.

[0056] The flexible belt 210 employs a composite fabric structure, consisting of an outer fabric, an inner lining, and a third fabric sewn together as a single unit. The outer fabric, located on the outermost layer, is typically made of abrasion-resistant materials such as nylon, polyester, or composite fibers. Its primary function is to protect the internal structure from external friction and damage, while also providing a degree of aesthetic appeal. The inner lining provides support and secures the mounting base 211 and the airbag 220. The innermost fabric, the flexible belt's innermost layer, comes into direct contact with human skin and is usually made of soft, breathable materials. Its main function is to provide a comfortable feel and reduce skin irritation.

[0057] In one specific implementation, the outer fabric is made of nylon. The inner fabric has a mesh structure and is woven from PHBV / PLA fibers and spandex. The lining is made of aramid fabric. The mesh structure significantly increases the overall breathability and heat dissipation of the flexible belt, reducing stuffiness and thus enhancing comfort during use. PHBV / PLA fibers have antibacterial and mite-repellent properties. The weaving of PHBV / PLA fibers and spandex gives the fabric elasticity, while the mesh structure reduces the contact area between the fabric and the skin, resulting in good skin contact and breathability, comprehensively improving the comfort of the massage belt.

[0058] The high strength of the aramid fabric provides stable support for the airbag 220, ensuring that the airbag 220 will not shift during use.

[0059] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
