Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of leg steaming devices, and more particularly to a far-infrared steaming barrel with a heat equalization partition structure. Background Technology
[0002] In the fast-paced urban life, many people are constantly rushing between work and life, often feeling stressed and exhausted, needing appropriate ways to regulate their mind and body and relieve stress. Foot soaking is an excellent method. Immersing the feet in hot water promotes blood circulation, increases blood flow, accelerates metabolism, and helps provide the body with more oxygen and nutrients. It also stimulates acupoints; the feet have many reflex points related to the body's internal organs, nervous system, and circulatory system. Stimulating these reflex points can promote the coordinated operation of various organs and systems, enhance the body's immunity, relieve muscle fatigue, and improve sleep quality. However, foot soaking requires holding hot water, and after soaking, the waste water needs to be poured out and the foot soak container cleaned. To simplify this process while still achieving the effect of leg heat therapy, engineers have designed a sauna barrel with electrically heated heating elements to achieve waterless foot therapy. In the sauna barrel, to prevent direct skin contact with the heating element surface and to prevent electric shock, an insulating plate is installed. This insulating plate is usually made of high-temperature resistant glass or metal mesh. Far-infrared mica heating plates that emit far-infrared rays can convert electrical energy into heat energy while simultaneously emitting far-infrared radiation. The principle behind this is that the surface of the mica plate is coated with far-infrared radiating materials, such as zirconium oxide, silicon carbide, inorganic ceramics, or graphene. It is well known that far-infrared rays in the 8-14 micrometer wavelength band can be directly absorbed by skin tissue, promoting blood circulation and tissue metabolism. Using quartz glass that transmits far-infrared rays is too expensive, and metal mesh is not suitable as it reflects far-infrared rays. Utility Model Content

[0032] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.
[0033] Please refer to Figures 1 to 15 This is a specific embodiment of the far-infrared sauna barrel with a uniform heat distribution structure disclosed in this technical solution. The barrel body 1 of this embodiment is designed with a rectangular cross-section and chamfered corners. The far-infrared sauna barrel includes a barrel body 1 with a hollow interior and an open top. The inner wall of the barrel body 1 includes four straight walls. Four far-infrared mica heating plates 3 are provided on the inner wall of the barrel body 1. Each of the four far-infrared mica heating plates 3 has a heat-insulating corner sleeve 304 made of silicone. A control unit is provided inside the barrel body 1. The far-infrared mica heating plates 3 are electrically connected to the control unit. A heat-insulating plate 2 is provided on the back of the far-infrared mica heating plate 3. A uniform heat distribution structure is provided on the front of the far-infrared mica heating plate 3, surrounding the interior of the barrel body 1. The uniform heat distribution structure is a bamboo partition curtain 4 with uniformly spaced vertical gaps. The gaps in the bamboo partition curtain 4 effectively prevent direct contact with the high-temperature far-infrared mica heating plate 3, thus preventing burns, while allowing the far-infrared rays generated by the far-infrared mica heating plate 3 to pass through the gaps and irradiate the feet. Preferably, the bamboo partition curtain 4 is made by weaving several thin bamboo strips arranged at even intervals as warp threads, then joined by connecting threads to form weft threads. Figure 15 (As shown). Preferably, the thin bamboo strips retain the bamboo skin side, and the bamboo skin side of the bamboo partition curtain 4 faces inward. Since bamboo skin has low water absorption and repellent properties, using bamboo partition curtain 4 facilitates cleaning.
[0034] Please refer to Figures 1 to 5 The far-infrared mica heating plate 3 has a through hole 301 at its center. A first protrusion 302 and a second protrusion 303 are respectively provided on the front and back sides of the far-infrared mica heating plate 3 at the through hole 301. The first protrusion 302 and the second protrusion 303 are connected and fixed by screws inserted into the through hole 301. The first protrusion 302 abuts against the back of the bamboo partition curtain 4, forming a gap between the back of the bamboo partition curtain 4 and the front of the far-infrared mica heating plate 3. The second protrusion 303 abuts against the front of the heat insulation plate 2, forming a gap between the back of the far-infrared mica heating plate 3 and the front of the heat insulation plate 2. The heat insulation plate 2 is used to separate the heat generated by the far-infrared mica heating plate 3 from the inner wall of the barrel 1, preventing the side wall of the barrel 1 from being affected by high temperatures.
[0035] Please refer to Figure 6 As a preferred structural design for the barrel body 1, a two-section design is adopted. The barrel body 1 includes a lower shell 11 and an upper shell 12, both formed by plastic injection molding. The bottom of the lower shell 11 has multiple protruding edges 111 arranged along its sides. The outer side of each protruding edge 111 serves as a bottom insertion limit for the bamboo partition curtain 4. The inner wall of the upper shell 12 has slots 121 for inserting the far-infrared mica heating plate 3. These slots 121 have an "L"-shaped cross-section, and are arranged facing each other on the inner wall of the upper shell 12, forming guide slots for inserting and fixing the far-infrared mica heating plate 3, making installation of the far-infrared mica heating plate 3 very convenient. Through this two-section design, the barrel body 1 can be customized to meet specific needs, such as for taller consumers who require a deeper barrel body. This can be achieved by simply increasing the height of either the upper shell 12 or the lower shell 11, without requiring a complete mold design, thus saving development costs.

The addition of the electrically heated glass plate 7 at the bottom enables heating and sweating of the soles of the feet, stimulating acupoints on the soles of the feet. The fixing frame 8 is fixedly connected to the mounting position by screws. The mounting position has screw connecting posts at the four corners and the fixing frame 8 has corresponding screw holes to press the electrically heated glass plate 7 placed at the bottom of the fixing frame 8. A sealing strip 81 is provided to prevent sweat from entering the bottom of the electrically heated glass plate 7 from the edge. The sealing strip 81 is preferably made of silicone.
