Description

Technical Field

[0001] The utility model relates to the field of carbon nano self-heating knee pads, and more specifically, to a novel carbon nano self-heating knee pad. Background Art

[0002] Knee pads are items used to protect people's knees. They have the functions of sports protection, cold protection, and joint care. They are divided into sports knee pads and health knee pads. They are suitable for athletes, middle-aged and elderly people, and patients with knee diseases.

[0003] The existing knee pads have a single structure and poor warmth retention. They cannot heat up by themselves and need to use electric energy to heat up, etc. For example, CN217509942U provides an electric heating knee pad, which belongs to the technical field of knee pads. The electric heating knee pad includes a knitted knee pad body, a heating wire, a power cord assembly and a power module. The knitted knee pad body is a long cylindrical structure. The heating wire is implanted in a first preset position of the knitted knee pad body, so that the heating wire is bent in multiple places to form a preset shape. The power cord assembly is implanted in a second preset position of the knitted knee pad body, and the power module is implanted in a third preset position of the knitted knee pad. The heating wire is electrically connected to the power module through the power cord assembly. Electric heating is more dangerous and easy to slip off when worn. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-4A novel carbon nano self-heating kneepad comprises a kneepad body 1, the inner surface of the kneepad body 1 is covered with a heating layer 2, the inner side of the heating layer 2 is distributed with carbon nanotubes 3, the inner side of the kneepad body 1 is covered with a thickening layer 4 (the thickening layer 4 is flannel, which is warmer), a first shrink tube 5 is fixed to the inner surface of the upper end of the kneepad body 1, and a second shrink tube 6 is fixed to the inner surface of the lower end of the kneepad body 1;

[0024] The inner surfaces of the first shrinkable tube 5 and the second shrinkable tube 6 are fixed with anti-slip strips 7, and the anti-slip strips 7 are arranged in three groups on one side on the inner surfaces of the first shrinkable tube 5 and the second shrinkable tube 6;

[0025] The back of the heating layer 2 is provided with a Velcro 20, which is bonded to the inner surface of the kneepad body 1 through the Velcro 20. The Velcro 20 adopts a ring structure, and the upper and lower groups are distributed on the back of the heating layer 2, which is bonded and installed, and can be removed when cleaning, and the bonding is stable;

[0026] The first shrink tube 5 and the second shrink tube 6 are made of elastic cloth, and the outer ends thereof are contracted. The anti-slip strip 7 is made of soft silicone strip. When worn, it can be tightened on the legs through the shrink tube, and the inner end is provided with the anti-slip strip 7 of silicone material to fit the legs, which can increase the friction and is not easy to slip off after wearing. The carbon nanotubes 3 are spirally distributed on the inner surface of the heating layer 2. The heating layer 2 is made of knitted fabric. The carbon nanotubes 3 are self-heated to improve the protection and heat preservation. 1) The heating mechanism of the carbon heating material: when electricity is turned on (friction static electricity), carbon molecules produce atoms, ions and electrons, and the carbon molecular groups rub and collide with each other (also called Brownian motion) to generate heat energy. The heat energy is radiated in the form of far infrared rays with a wavelength of 5-14 microns, and the effective electrothermal conversion rate can reach more than 90%. For materials with some carbon nanotubes added, due to the superconductivity of the carbon nanotube material, its heating performance is more stable, and the electrothermal conversion efficiency can reach 99%. Compared with the heating of traditional carbon materials, it has the characteristics of large power per unit area and high energy efficiency, which effectively reduces the usage area.

[0027] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
