Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically to a spinal electrotherapy pad. Background Technology

[0002] With the prevalence of modern office work patterns, prolonged sitting can easily lead to problems such as stiff back muscles, lumbar strain, and poor blood circulation. Spinal electrotherapy cushions, as portable physiotherapy devices, are widely used in homes and offices. With the continuous development of physiotherapy cushion products, spinal electrotherapy cushions integrating electrical stimulation and heat therapy functions are becoming increasingly popular. Heat therapy can relax muscles and promote local blood circulation, which, combined with the electrotherapy electrodes applied to the back, can significantly enhance the therapeutic effect.

[0003] Most existing spinal electrotherapy pads use a built-in heating wire design, with the heating wire located deep within the pad's internal layers. The surface of the pad is where the heating wire contacts the body, and the heating wire is relatively far from the surface. During the heating start-up phase, heat needs to travel a considerable distance to reach the pad's surface. This long heat conduction path and significant heat loss result in slow heating and a long waiting time. Users also experience a poor user experience as they have to wait a long time to feel the warmth after activating the heat therapy function.

[0004] Meanwhile, the heating wire is deeply embedded inside the pad, resulting in slow heating response and potential issues such as heat accumulation inside the pad and uneven surface temperature. The area where the electrode pads are located also experiences delayed heating, preventing the heat therapy and electrotherapy from working simultaneously. Furthermore, the heating wire is far from the contact surface, leading to low heat transfer efficiency and high overall power consumption. Therefore, existing integrated heat therapy back electrotherapy pads suffer from technical problems such as slow heating, long heat conduction paths, difficulty in quickly transferring heat to the pad surface, poor temperature uniformity, and high power consumption. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide a spinal electrotherapy pad with a short heat conduction path, fast heating speed, greatly improving the user experience, high temperature uniformity, and lower power consumption.

[0006] The objective of this invention is achieved through the following technical solution: A spinal electrotherapy pad includes a main body and a heating wire. The main body comprises a lower pad and an upper pad. The upper pad has multiple hollow support protrusions. Each hollow support protrusion is upwardly protruding and forms a cavity inside. The hollow support protrusions are electrode-type hollow support protrusions. The lower pad has multiple upwardly protruding pads. The multiple hollow support protrusions and pads are arranged in a one-to-one correspondence, and the pads are inserted into the cavities. The heating wire includes multiple heating segments, which are arranged in a one-to-one correspondence with the multiple hollow support protrusions. The heating segments are installed between the top of the cavity and the top of the pads.

[0007] The working principle of the above-mentioned spinal electrotherapy pad is as follows: The electrode-type hollow support protrusion contacts the back of the human body, stimulating muscles and nerves with electric current to achieve muscle relaxation therapy. The heating wire generates heat, which is conducted to the surface of the hollow support protrusion to warm the back of the human body, relaxing muscles, promoting local blood circulation, and improving the comfort of electrotherapy. The pad is inserted into the cavity, providing good support for the hollow support protrusion. Because the heating section is installed between the top of the cavity and the top of the pad, the heat generated by the heating section is directly transferred to the surface of the hollow support protrusion. The heat conduction path is short, the heating speed is fast, greatly improving the user experience and also improving temperature uniformity. The heating section is close to the back of the human body, resulting in high heat transfer efficiency and lower power consumption.

[0008] In a preferred embodiment of the present invention, the electrode-type hollow support protrusion includes a support member disposed on an upper pad and a conductive electrode assembled on the upper end of the support member; the cavity is formed inside the support member, and the cavity is a through-cavity. In the above structure, the electrode-type hollow support protrusion adopts a split structure, which allows the conductive electrode to be independently disassembled and replaced, decoupling the structure from the conductive function, and allowing for more flexible material selection; the conductive electrode contacts the back of the human body, providing an electrotherapy effect, and when the heating segment heats up, it transfers heat to the conductive electrode.

[0009] Preferably, a receiving gap is provided between the top of the pad and the lower end face of the conductive electrode, and the heating segment is located in the receiving gap; the heating segment is arranged in a circuitous manner within the receiving gap. With the above structure, the heating segment is in direct contact with the conductive electrode, and the heat of the heating segment can be directly transferred to the conductive electrode. The conductive electrode is in contact with the back of the human body, resulting in a short heat conduction path. In addition, the circuitous arrangement of the heating segment can further improve temperature uniformity and ensure uniform heating of the surface of the conductive electrode.

[0010] Furthermore, the heating segment is in close contact with the lower end face of the conductive electrode. This is to ensure that the heat from the heating segment can be quickly transferred to the conductive electrode.

[0011] Preferably, the heating segments arranged in each accommodating gap are connected in series via heating connecting segments, which are integral structures with the heating segments. By setting heating connecting segments, the heating segments are connected, and the heating connecting segments are integral structures with the heating segments. That is, the spinal electrotherapy pad includes only one heating wire. By arranging the wiring of this heating wire, the heating segments and heating connecting segments are formed. The structure is simple, and the heating connecting segments can also provide a heating effect, realizing the heat therapy function in other areas.

[0012] Preferably, the conductive electrode is made of conductive silicone, and the conductive silicone is connected to a wire. By using conductive silicone, it fits the back of the human body better. The conductive silicone can adapt to deformation, ensuring stable contact between the conductive silicone and the back of the human body. The wire can be used for electrode signal transmission.

[0013] Preferably, the lower pad is provided with a wiring groove. The wiring groove facilitates the routing of the wires to the heating connection section.

[0014] Preferably, one of the hollow support protrusions is a neck hollow support protrusion, and the remaining hollow support protrusions are back hollow support protrusions; the back hollow support protrusions are distributed on both sides of the midline along the length of the upper pad, and the neck hollow support protrusions are located at the end of the midline along the length of the upper pad. By setting the above structure, electrotherapy and heat therapy can be applied to the neck and back of the human body, achieving physiotherapy effects on multiple parts of the back.

[0015] Preferably, the wiring channel includes a main channel located at the centerline of the lower pad along its length and branch channels located between each pad and the main channel. This structure facilitates the routing of the wires and the heating connection section, resulting in a very neat wiring harness. Simultaneously, the heating connection section can heat the other heating sections, providing a certain degree of heat therapy to the spine area on the back.

[0016] Preferably, the electrotherapy pad body is provided with a wiring port, which is connected to the heating wire and the lead wire. By providing the wiring port, it can be used to connect to the output of the main unit.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The spinal electrotherapy pad of the present invention, by setting a pad block and a hollow support protrusion, the heating section of the heating wire is installed between the top of the cavity and the top of the pad block. The heat generated by the heating section is directly transferred to the surface of the hollow support protrusion. The heating section is close to the surface of the hollow support protrusion, the heat conduction path is short, the heating speed is fast, which greatly improves the user experience and also improves the temperature uniformity. The heating section is close to the back of the human body, the heat transfer efficiency is high, and the power consumption is lower.

[0018] 2. The spinal electrotherapy pad of the present invention has a pad block inserted into the cavity. The pad block provides good support for the hollow support protrusion. During use, it prevents the hollow support protrusion from collapsing and ensures stable support for the human back.

[0019] 3. The spinal electrotherapy pad of the present invention comprises a lower pad and an upper pad, which are separate components. This makes it extremely convenient to install the heating wire. Furthermore, when the heating wire, wires, or other internal electrical components of the electrotherapy pad are damaged, the lower and upper pads can be disassembled and separated to repair the electrical components. Compared to an integrated electrotherapy pad, the present invention has lower repair costs. Attached Figure Description
