Description

Technical Field

[0001] The present invention belongs to the technical field of moxibustion equipment, and in particular relates to a smokeless moxibustion device and method for Neiguan acupoint. Background Art

[0002] Moxibustion is one of the three major treatments in traditional Chinese medicine, along with decoctions and acupuncture. It has long been an important means of treating diseases in traditional Chinese medicine. It mainly uses burning moxa sticks to warm and stimulate the acupuncture points of the human body, thereby achieving the effects of warming the meridians and dispelling cold, promoting blood circulation and removing blood stasis, and regulating qi and blood. The therapeutic effect of moxibustion comes from multiple factors such as warm stimulation, light radiation, and harmful substances generated by combustion. In particular, warm stimulation can improve the therapeutic effect by dilating capillaries, promoting metabolism, and enhancing the absorption of nutrients. Accurate temperature control is the key to the moxibustion process. Too high or too low a temperature may affect the therapeutic effect and even cause burns.

[0003] Traditional moxibustion methods usually rely on manual operations or simple moxibustion instruments, which have shortcomings. Manual moxibustion requires manual adjustment of the distance between the moxa stick and the skin. The operation is cumbersome and cannot guarantee precise temperature control, which can easily lead to temperature fluctuations and increase the risk of burns. Traditional moxibustion devices are mostly heated by air outlet adjustment or mechanical adjustment, with low precision and slow response, and cannot cope with rapidly changing environmental conditions or differences in user physique. In addition, the burning of moxa sticks will produce a lot of smoke and dust, which not only affects the use environment, but may also have adverse effects on the respiratory tract. The existing moxibustion equipment has a single function, and it is difficult to implement complex moxibustion methods such as sparrow pecking moxibustion and spiral moxibustion. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a smokeless moxibustion device and method for Neiguan acupoint, wherein the moxibustion module is fixed at the Neiguan acupoint by an elastic strap, and the mode control of the moxibustion module is realized by a control module. The smokeless moxibustion device can realize intelligent and precise temperature control through its control method, realize multiple modes of moxibustion, and bring a safer, more convenient and comfortable moxibustion experience.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A smokeless moxibustion device for Neiguan acupoint comprises an elastic band 2, one end of which is provided with a Velcro 1, a moxibustion module 3 is provided on the elastic band 2, and the moxibustion module 3 is connected to a control module 4 through a line 5.

[0007] The moxibustion module 3 includes a hollow shell 11, a pressure sensor 6 and a temperature sensor 7 are arranged on the surface of the shell 11, and replaceable moxibustion essential oil tablets 8, thermal conductive silicone grease 9 and a heating plate 10 are stacked in sequence inside the shell.

[0008] The heating sheet 10 is a geometric array composed of multiple heating resistor sheets. The geometric array is arranged in a matrix form. Each heating resistor sheet is equipped with an independent field effect transistor switch. Each heating resistor sheet is connected in series independently and then in parallel to the power supply circuit. The independently controlled switch adjusts the thermoelectric power to realize the adjustment of the heating space size and position.

[0009] The control module 4 is built-in with a Bluetooth unit 12. The signal output end of the Bluetooth unit 12 is connected to the signal receiving end of the controller 13, and the signal output end of the controller 13 is connected to the heating sheet 10 to realize temperature control.

[0010] The data receiving end of the controller 13 is connected to the pressure sensor 6 and the temperature sensor 7.

[0011] The control module 4 is preset with a mild moxibustion mode, a pecking moxibustion mode, and a rotating moxibustion mode.

[0012] The mild moxibustion mode performs moxibustion on the acupoint by continuously providing heat.

[0013] The pecking moxibustion mode simulates the pecking moxibustion operation through periodic heating power fluctuations.

[0014] The rotating moxibustion mode simulates the rotating moxibustion operation through dynamic switching of the heating area.

[0015] A smokeless moxibustion method for the Neiguan acupoint, using the above device, includes the following steps:

[0016] S1: First, wind the elastic band 2 around the wrist, and then fix the elastic band 2 through the magic tape 1, so that the moxibustion module 3 is placed at the Neiguan acupoint position, and wirelessly connect to the mobile terminal through the Bluetooth unit 12.

[0017] S2: Detect the fitting degree through the pressure sensor 6. When the fitting degree reaches the preset threshold, use the mobile terminal to remotely control the control module 4 to start the heating sheet 10.

[0018] S3: Real-time monitor the skin temperature through the temperature sensor 7. The control module 4 dynamically adjusts the heating power of the heating sheet 10 according to the preset mode to keep the temperature within the range of 42 - 46 °C.

[0019] S4: When the heating time reaches the set value, the control module 4 automatically turns off the heating sheet 10.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Through the control of the heating sheet 10 by the control module 4, the present invention realizes precise temperature control. Combined with the elastic strap 2 and the pressure sensor 6, while ensuring the precise positioning of the Neiguan acupoint, it can dynamically sense the skin fit and automatically adjust the heating power, completely solving the problems of large temperature fluctuations (more than ±5°C) in traditional moxibustion and easy scalding caused by manual operation. The use of replaceable moxa essential oil tablets instead of open-flame combustion realizes smokeless penetration of medicinal effects and meets the indoor environmental protection requirements.

[0022] 2. The control module 4 of the present invention supports intelligent switching of multiple traditional Chinese medicine classic moxibustion methods such as the preset mild moxibustion mode, pecking moxibustion mode, and revolving moxibustion mode, breaking through the limitation of single function of traditional devices. With a lightweight design, it can be worn all day long in scenarios such as work and commuting, especially suitable for the fragmented health management needs of modern urban people.

[0023] 3. The present invention integrates a Bluetooth unit 12, and a customized moxibustion plan can be set through a mobile terminal application. Users can adjust the temperature curve and moxibustion method combination according to their physical characteristics. The system is built-in with a safety protection mechanism, which can automatically cut off the power and push warning information when the pressure or temperature is abnormal, realizing a safe moxibustion experience with zero manual attendance.

[0024] In summary, the present invention has the characteristics of intelligence, environmental protection, universality, safety, precise control, and diverse modes. Brief Description of the Drawings

Detailed Embodiment

[0030] The following describes in detail the structural principle and working principle of the present invention with reference to the drawings.

[0031] As Figure 1As shown, a smokeless moxibustion device for Neiguan acupoint includes an elastic band 2, one end of which is provided with a Velcro 1, and a power supply. The elastic band 2 is provided with a moxibustion module 3, and the moxibustion module 3 is connected to the control module 4 through a line 5.

[0032] Furthermore, the elastic bandage 2 is provided with acupoint location size marks, which is convenient for positioning the Neiguan acupoint when worn on the wrist bone. The elastic bandage 2 is made of elastic cotton cloth, which has elasticity, heat preservation and appropriate breathability to ensure comfort for long-term wearing.

[0033] Furthermore, the Velcro 1 is used to adjust the elastic strap 2 so that it is suitable for arms of different thicknesses, ensuring accurate moxibustion.

[0034] like Figure 2 As shown, the moxibustion module 3 includes a hollow shell 11, a pressure sensor 6 and a temperature sensor 7 are arranged on the surface of the shell 11, and replaceable moxibustion essential oil tablets 8, thermal grease 9 and a heating plate 10 are stacked in sequence inside the shell.

[0035] Furthermore, the pressure sensor 6 is used to detect the fitting pressure between the elastic bandage 2 and the skin, with an operating range of 5 to 20 kPa, to ensure close contact between the moxibustion device and the skin, improve the moxibustion effect, and avoid temperature fluctuations caused by uneven pressure.

[0036] Furthermore, the temperature sensor 7 is attached to the surface of the housing 11 to monitor the temperature of the skin contact surface in real time to ensure the accuracy of the temperature feedback.

[0037] Furthermore, the replaceable moxibustion essential oil tablets 8 can be loaded before each moxibustion and taken out after use to ensure the medicinal effect of each moxibustion.

[0038] Furthermore, the replaceable moxibustion essential oil tablets 8 are formed by pressing the wormwood extract through a scientific formula, with a thickness of 2 to 3 mm, and can slowly release the medicinal effect during the moxibustion process. The medicinal ingredients of wormwood mainly include: volatile oil, which has the effects of warming the meridians and dispelling cold, promoting blood circulation and removing blood stasis, helping to improve local blood circulation and relieve muscle soreness; wormwood flavonoids, which have antioxidant effects, can help relieve physical fatigue and enhance immunity. During the treatment process, the replaceable moxibustion essential oil tablets 8 not only regulate the body's qi and blood through warm stimulation, but also release natural herbal ingredients, which are absorbed through the skin to exert deep therapeutic effects, thereby providing a more comprehensive therapeutic effect.

[0039] Furthermore, a thermal conductive silicone grease 9 is disposed on the outside of the heating plate 10 to effectively reduce heat loss, maintain high efficiency of heat transfer and heating system, and also ensure thermal efficiency and safety of use of the equipment.

[0040] The heating sheet 10 is a geometric array composed of multiple heating resistor sheets. The geometric array is arranged in a matrix form. Each heating resistor sheet is equipped with an independent field-effect transistor switch. Each heating resistor sheet is connected to the power supply circuit in series independently and then in parallel. The separately controlled switches adjust the thermoelectric power to achieve the adjustment of the heating space size and position.

[0041] Furthermore, the heating sheet 10 is composed of multiple heat-generating thermocouples, which can accurately control the on-off of the current to achieve precise control of resistance heating. In this way, the present invention can dynamically adjust the heating power and heating position without relying on mechanical adjustment, so as to achieve precise temperature control.

[0042] As Figure 3 shown, the control module 4 integrates a Bluetooth unit 12. The signal output end of the Bluetooth unit 12 is connected to the signal receiving end of the controller 13, and the signal output end of the controller 13 is connected to the heating sheet 10 to control its temperature;

[0043] The data receiving end of the controller 13 is connected to the pressure sensor 6 and the temperature sensor 7.

[0044] The control module 4 is preset with mild moxibustion mode, pecking moxibustion mode and revolving moxibustion mode;

[0045] The mild moxibustion mode performs moxibustion on acupoints by continuously providing heat;

[0046] The pecking moxibustion mode simulates the pecking moxibustion operation through periodic heating power fluctuations;

[0047] The revolving moxibustion mode simulates the revolving moxibustion operation by dynamically switching the heating area.

[0048] Furthermore, the control module 4 of the present invention integrates a Bluetooth unit 12. Users can remotely set moxibustion modes (such as mild moxibustion, pecking moxibustion, revolving moxibustion, etc.) through a mobile phone APP, and can also monitor data such as temperature and time in real time. Users can select different moxibustion modes. For example, in the pecking moxibustion mode, the system alternately switches the target temperature between 42°C and 46°C at a preset frequency (such as 6 times per minute) to simulate the treatment technique of pecking moxibustion. Another example is the revolving moxibustion mode. By controlling the power and time of the heating sheet, the effect of revolving moxibustion is simulated to achieve precise acupoint stimulation.

[0049] Furthermore, the remote operation and data recording functions make the moxibustion process more convenient. Users can make real-time adjustments according to personal needs, and ensure the accuracy and efficiency of the treatment process.

[0050] A smokeless moxibustion method for the Neiguan acupoint, using a smokeless moxibustion device for the Neiguan acupoint, includes the following steps:

[0051] S1: First, wrap the elastic band 2 around the wrist, and then fix the elastic band 2 with the magic tape 1 so that the moxibustion module 3 is placed at the Neiguan acupoint position, and wirelessly connect to the mobile terminal through the Bluetooth unit 12;

[0052] S2: Detect the fitting degree through the pressure sensor 6. When the fitting degree reaches the preset threshold, use the mobile terminal to remotely control the module 4 to start the heating sheet 10;
