Description

Technical Field

[0001] This utility model relates to the field of sauna barrel technology, and in particular to a far-infrared heat therapy barrel. Background Technology

[0002] A foot bath tub is a household product. Most foot bath tubs on the market currently utilize warm steam applied to the feet, leveraging the rich meridians and acupoints of the feet to regulate overall bodily functions—a health-preserving method. It uses the warmth of the steam to promote blood circulation in the feet and throughout the body, resulting in a series of health benefits. However, uneven steam distribution and temperature affect the effectiveness of the product; the usage time is relatively short when full of water (approximately 20 minutes); and the large amount of steam creates a damp environment, negatively impacting the user experience.

[0003] Therefore, we propose a far-infrared heat therapy barrel based on infrared photonic crystal heating technology. Utility Model Content

[0020] This utility model proposes a far-infrared heat therapy barrel.

[0021] like Figures 1 to 6As shown, in one embodiment of this utility model, the far-infrared heat therapy barrel includes a barrel body 101, a heat-conducting inner shell 102, an infrared radiation heating wire 103, an infrared radiation heating plate 104, and an upper shell 105. The heat-conducting inner shell 102 is embedded in the barrel body 101. The infrared radiation heating wire 103 is wound around the outer or inner peripheral wall of the heat-conducting inner shell 102. The infrared radiation heating wire 103 includes a core material 1031, a first reflective coating 1032, and a first photonic crystal infrared radiation heating coating 1033. The first reflective coating 1032 is disposed on the outer peripheral wall of the core material 1031, and the first photonic crystal infrared radiation heating coating 1033 is disposed on the outer peripheral wall of the first reflective coating 1032. The infrared radiation heating plate 104 is disposed at the bottom of the heat-conducting inner shell 102. The infrared radiation heating plate 104 includes a substrate 1041 and a second reflective coating. The substrate 1042 and the second photonic crystal infrared radiation heating coating 1043 are respectively disposed on the lower end wall of the substrate 1041 and the second photonic crystal infrared radiation heating coating 1043 is disposed on the upper end wall of the substrate 1041. The upper housing 105 is disposed on the upper end of the heat-conducting inner housing 102. The upper end of the upper housing 105 is provided with an opening 1051 for two feet to be inserted. The upper housing 105 is provided with a control main board (not shown). The control main board is provided with an infrared radiation driving circuit. The infrared radiation driving circuit is electrically connected to the second photonic crystal infrared radiation heating coating 1043. The infrared radiation heating wire 103 is electrically connected to the control main board. While generating heat, the first photonic crystal infrared radiation heating coating 1033 and the second photonic crystal infrared radiation heating coating 1043 can also release far-infrared rays with a wavelength of 8.0μm to 20μm, which has a physiotherapy and health care effect.

[0022] Specifically, the upper wall of the upper housing 105 is provided with an LCD screen 1052, a touch button 1053, and a status indicator light 1054 that are electrically connected to the control motherboard.

[0023] Specifically, it also includes a temperature sensor (not shown). The temperature sensor is set on the inner peripheral wall and the inner bottom wall of the heat-conducting inner shell 102. The temperature sensor is electrically connected to the control motherboard and can monitor the problems of the heat-conducting inner shell in real time, so that the physiotherapy barrel has a temperature control function to avoid the temperature being too high or too low.

[0024] Specifically, the inner circumferential wall of the barrel 101 is provided with a heat insulation layer (not shown) to reduce heat transfer and lower energy consumption.

[0025] Specifically, the thermal insulation layer is formed using vacuum insulation panels. Vacuum insulation panels (VIP panels) are a type of vacuum insulation material, which is composed of a core material and a vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, thus significantly reducing the thermal conductivity to 0.002-0.004 W / mK, which is 1 / 10 of the thermal conductivity of traditional insulation materials. Vacuum insulation panels are mainly composed of core material, barrier film, and getter, thereby achieving a good thermal insulation effect.

[0026] Specifically, it also includes a movable cover 106, which is detachably installed on the upper end of the opening 1051 and serves to prevent dust when the physiotherapy tub is not in use.

[0027] Specifically, it also includes omnidirectional casters (not shown), which are respectively set at the four bottom corners of the lower end wall of the barrel 101 to facilitate the movement of the physiotherapy barrel and allow the physiotherapy barrel to be moved at will.

[0028] Specifically, the far-infrared light emitted by the first photonic crystal infrared radiation heating coating 1033 and the second photonic crystal infrared radiation heating coating 1043 both have a wavelength range of 8.0μm to 14μm, which is consistent with the optimal wavelength range for human biological effects. This allows for faster and more uniform heat generation, and the concentrated and stable energy of the infrared radiation significantly improves the heating effect, enhances the precision and energy utilization of thermotherapy, and effectively improves the therapeutic effect.

[0029] Specifically, the mechanism by which this invention excites far-infrared light through a photonic crystal infrared radiation heating coating is as follows: Photonic crystals are materials with periodic refractive indices or dielectric constants. The periodic structure of a photonic crystal can interact with the plasmon resonance effect on the surface of a metal thin film, thereby enhancing light of specific wavelengths on the surface. By controlling the structural parameters of the photonic crystal, the resonant frequency can be adjusted, thus exciting the emission of infrared light. Furthermore, the emitted infrared band can be flexibly controlled by changing the lattice size of the photonic crystal. The second photonic crystal infrared radiation heating coating, through a three-dimensional photonic crystal structure design, introduces a photonic bandgap and is designed to achieve efficient heating of specific wavelengths based on the infrared absorption peaks of different materials. It utilizes the infrared radiation effect of the photonic crystal to achieve high efficiency, low energy consumption, and uniform heating. Far-infrared rays are hailed as the "light of life" by the modern medical community. Studies have shown that the human body is a good absorber of far-infrared rays with a wavelength greater than 6μm. After receiving far-infrared rays, the human body's tissues and cells resonate and absorb them, which can enhance activity and promote metabolism. The photonic crystal infrared radiation heating coating of this utility model not only generates heat but also emits far-infrared radiation with a wavelength of 8.0μm to 14μm, which can play a role in far-infrared health care and radiation therapy for the human body. In terms of physiological effects, the highly efficient far-infrared heat therapy can effectively improve blood circulation, relieve muscle fatigue, activate cells and promote metabolism, dredge meridians, dispel wind and dampness, relieve pain and cold, and enhance the body's disease resistance.

[0030] The photonic crystal infrared radiation heating coating has excellent thermal conductivity, heats up quickly, and can rapidly reach the preset temperature after being powered on. It also heats up evenly, maintaining overall temperature uniformity during the heating process to avoid local overheating. Furthermore, it has a long service life, is energy-efficient, and has high heat conversion efficiency, effectively converting electrical energy into heat energy and reducing energy waste.

[0031] This invention can effectively relieve cold hands and feet and knee pain. The far-infrared rays resonate with water molecules in the human body, accelerating blood circulation and warming the body. Deep warmth is delivered from the feet to the whole body.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
