Description

Portable heater

Technical Field

The invention relates to a portable warmer.

Background

The warmer is a heating device which is common in winter. Except for the electric blanket, a small warmer is common, and is laid on the ground for warming feet or on a table top for warming hands or on legs for warming the legs in winter.

However, the small-sized warmer in the prior art is made of rubber materials, when the small-sized warmer is used, harmful substances are volatilized due to electric heating, and after researches on the warmer of 10 different shops purchased on the internet, 9 types of the warmer have large smell, and the rest of the warmer has no obvious peculiar smell, but has much higher price compared with other types of the warmer. In addition, in order to reduce the manufacturing cost, the products are not enough in safety protection, so that fire disasters are easy to happen, and the volume structure is large when the fire disasters are carried due to the inconvenience in rolling.

Therefore, a portable warmer which is small in size structure, easy to curl and store and good in safety performance is designed.

Disclosure of Invention

The invention aims to provide a portable warmer which is small in size and structure, easy to curl and store and good in safety performance.

In order to solve the problems, the invention adopts the following technical scheme:

a portable warmer comprises a heating part, a manual temperature control regulating switch and an infrared remote controller, wherein the manual temperature control regulating switch is used for controlling the heating temperature and time of the heating part; the polyester cotton layer, the bamboo mat layer, the heat preservation cotton layer, the reflection film layer and the heating sheet are sequentially and compositely connected from top to bottom, universal shaping bent pipes are mounted at the upper portion and the lower portion of the bamboo mat layer, and the universal shaping bent pipes are clamped between the polyester cotton layer and the heat preservation cotton layer.

Preferably, the heating sheet comprises an upper substrate layer and a lower substrate layer, and further comprises a high-temperature wire, a carbon fiber electric heating wire is connected in series on the high-temperature wire, a plurality of temperature limit switches are assembled on the high-temperature wire, and two ends of the high-temperature wire are connected with the manual temperature control adjusting switch; an aluminum foil layer is matched between the inner sides of the two substrate layers, and the high-temperature lead and the carbon fiber electric heating wire are arranged in the aluminum foil layer; and a temperature measuring probe is also assembled between the two aluminum foil layers and is connected with the manual temperature control regulating switch.

Preferably, one of them layer substrate layer is silver fiber material, and the opposite side substrate layer is the cotton material of dacron, and when using, the substrate layer laminating human of silver fiber material.

The raw material of the polyester cotton is polyester staple fiber. Generally solid, poor in elasticity and heat retention, heavy in feeling, generally unfinished and poor in quality. As the service time is prolonged, the elasticity of the fiber is damaged and the fiber is pressed to be dead, shrunk and agglomerated, and the cotton is commonly used as the filling material of low-grade home textiles.

The heat-insulating cotton is a novel non-toxic, harmless and pollution-free heat-insulating material prepared from high-purity clay clinker, alumina powder, silica powder, chrome quartz sand and the like.

The heat insulating cotton can be further processed into products such as fiber blankets, boards, paper, cloth, ropes and the like. The ceramic fiber is a high-efficiency heat-insulating material, and has the characteristics of light weight, oxidation resistance, low heat conductivity, good flexibility, corrosion resistance, small heat capacity, sound insulation and the like.

Reflective films can generally be classified into two broad categories, metallic reflective films and all dielectric reflective films. In addition, there is a metal dielectric reflective film combining both. In the present invention, a metal dielectric reflective film is preferably used.

Generally, metals have a large extinction coefficient, and when a light beam is incident from air to the surface of the metal, the amplitude of light entering the metal is rapidly attenuated, so that the light energy entering the metal is correspondingly reduced, and the reflected light energy is increased. The larger the extinction coefficient, the more rapidly the light amplitude decays, the less light energy enters the interior of the metal, and the higher the reflectivity. Those metals having a large optical coefficient and stable optical properties are always selected as the metal film material. The metal thin material commonly used in the ultraviolet region is aluminum, aluminum and silver are commonly used in the visible region, gold, silver and copper are commonly used in the infrared region, and chromium and platinum are also commonly used as film materials of some special films. Materials such as aluminum, silver, and copper are easily oxidized in air to deteriorate the performance, and therefore, must be protected by a dielectric film. Commonly used protective film materials include silicon monoxide, magnesium fluoride, silicon dioxide, aluminum oxide and the like.

The metal reflecting film has the advantages of simple preparation process and wide working wavelength range, and has the defects of large optical loss and impossible high reflectivity. In order to further improve the reflectance of the metal reflective film, the metal dielectric reflective film may be formed by plating several dielectric layers of a predetermined thickness on the outer side of the film. It should be noted that the metal dielectric reflective film increases the reflectivity at a certain wavelength (or a certain wavelength range), but destroys the neutral reflection characteristic of the metal film.

All dielectric reflective films are based on multi-beam interference. In contrast to antireflection coatings, a thin film with a refractive index higher than that of the substrate material is coated on the optical surface to increase the reflectivity of the optical surface. The simplest multilayer reflection is formed by alternately evaporating two materials with high and low refractive indexes, and the optical thickness of each film is one quarter of a certain wavelength. Under this condition, the reflected light vectors on the interfaces participating in the superposition have the same vibration direction. The composite amplitude increases with the number of layers of the film.

The mounting mode of the universal shaping elbow is as follows:

when the material is cut, the cutting width of the heat-insulation cotton layer is larger than that of the polyester cotton layer, then two ends of the heat-insulation cotton layer are curled, an opening inserted into the universal shaping bent pipe is formed after curling, then the universal shaping bent pipe is inserted into the opening formed by curling, and the two ends of the universal shaping bent pipe are plugged.

The bamboo mat layer is directly clamped in the heat insulation cotton layer and the polyester cotton layer, when the bamboo mat layer is installed, glue is brushed at the position of the bottom extending edge of the polyester surface layer, and then the polyester cotton layer and the heat insulation surface layer are glued and fixed in a gluing and fixing mode. In order to ensure the characteristics of the bamboo mat, glue is not brushed among the bamboo mat, the heat preservation cotton layer and the polyester cotton layer.

Before the bamboo mat layer is assembled, the extending position of the bamboo mat layer needs to be covered with the edge, so that damage to other structural components of the product caused by the fact that burrs of the bamboo mat layer are exposed outwards is avoided.

The invention has the beneficial effects that:

1. the volume is obviously reduced and the carrying is more convenient due to the structure of the winding drum;

2. can be put up and laid down, and can be unfolded and laid flat, thereby realizing multiple purposes;

3. the sheet can be transversely stretched or curled at any angle, and can be shaped and not easily deformed after being bent, so that the sheet can be used in different environments and different spaces;

4. the product is additionally provided with a plurality of temperature limit switches and a temperature control probe, so that multiple safety protection is realized.
