Description

Technical Field

[0001] This utility model relates to the field of sauna bath box technology, specifically a sauna bath box with a flexible heating plate. Background Technology

[0002] Sauna, also known as Finnish sauna, refers to the process of using steam to treat the body in a closed room. The temperature inside a sauna can typically reach over 60℃. Originating in Finland, saunas have a history of over 2000 years. Utilizing the repeated hot and cold stimulation of dry steam washing over the whole body, blood vessels repeatedly dilate and contract, enhancing vascular elasticity and preventing arteriosclerosis. In typical home saunas, a sauna tub is an indispensable piece of equipment. Sauna tubs, also called sauna barrels or exercise sweat machines, are a new type of beauty and health product that has gained popularity due to their foldable design, ease of storage, and convenient use. Their function is based on the principle of thermotherapy. A steam engine delivers steam into the tub, and when a person sits inside, the steam warms the skin, increasing the surface temperature and accelerating the activity of skin cells. This causes the capillaries on the skin's surface to dilate, expelling impurities accumulated in skin folds through sweat, thus achieving the effects of clearing meridians, increasing blood circulation, and detoxifying and beautifying the skin.

[0003] Traditional sauna boxes consist of a box frame, a box fabric covering the frame, and an electric heating device installed inside the box fabric. The traditional electric heating device uses a heating plate, which is attached to the inner box fabric in sheet form. Traditional sauna box heating has the following problems: 1. The heating plate is mostly located at the bottom of the inner box fabric, usually on the front and left / right sides (excluding the side where it enters). Using a large heating plate results in insufficient coverage, uneven heating, and poor performance. 2. The large heating plate also makes it difficult to roll up the box fabric, taking up a lot of space and hindering container shipping. Therefore, further optimization is urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sauna box with a flexible heating plate that offers wide heating coverage, excellent heating uniformity, small roll-up space, and detachable design.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A sauna box with a flexible heating element includes a rectangular box frame covered with a sauna sheet. The box frame divides the sauna sheet into a front sheet, a back sheet, a left sheet, a right sheet, a top sheet, and a bottom sheet. The front sheet has a lifting flap with an opening. A flexible heating element is detachably mounted on the inside of the sauna sheet. The flexible heating element includes, from top to bottom, an insulating fabric, a heating wire, and a needle-punched fabric. The heating wire is evenly sewn between the insulating fabric and the needle-punched fabric.

[0007] Preferably, the flexible heating element is provided with a zipper mother strip around its perimeter, and the sauna bath cloth is provided with a zipper daughter strip. The flexible heating element is detachably mounted on the sauna bath cloth through the zipper structure of the zipper mother strip and the zipper daughter strip.

[0008] Preferably, the flexible heating element is provided with Velcro around its perimeter, and the sauna bath cloth is provided with Velcro tabs. The flexible heating element is detachably mounted on the sauna bath cloth via the Velcro and Velcro tabs.

[0009] Preferably, the flexible heating element is detachably mounted on the rear bath cloth, left bath cloth, and right bath cloth.

[0010] Preferably, the lifted cloth is provided with a viewing window.

[0011] Preferably, a light panel is provided on the top shower cloth.

[0012] Preferably, a heating pedal is provided on the bath bath cloth.

[0013] Preferably, the bathtub frame includes a support rod and a T-joint, wherein the support rod is detachably connected via the T-joint to form a cuboid bathtub frame.

[0014] Preferably, the sauna bath cloth is made of Oxford cloth, the heat insulation cloth is made of plush cloth, and the needle-punched cloth is made of cotton cloth.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a sauna box with a flexible heating element. The flexible heating element has an overall detachable structure, which can cover the entire sauna bath cloth, providing wide coverage. Furthermore, the heating wires are evenly sewn between the insulation cloth and the needle-punched cloth, ensuring uniform heating and avoiding the situation where the upper side is cold and the lower side is hot.

[0017] This utility model features a sauna box with a flexible heating element. The flexible heating element is composed of three parts: insulation cloth, heating wire, and needle-punched cloth, which makes it sufficiently flexible, detachable, and rollable, greatly reducing the space occupied, facilitating container shipping, and making it more practical.
