Description

A kind of far-infrared heating and warming insole

technical field

The utility model relates to a thermal insole, in particular to a far-infrared heating thermal insole.

Background technique

Thermal insoles are used more and more commonly in daily life. The existing thermal insoles are generally composed of insoles and heating elements arranged in the insoles to realize the conversion of electrical energy into heat energy. This can play a role in keeping warm. But in the process of wearing, there will also be airtight, not soft, and uncomfortable phenomena, and some thermal insole devices with external connection circuits usually do not keep warm for a long time. Due to long-term wearing, the insole heating device is easy to be damaged and loses thermal performance. ; At the same time, it is inconvenient to go out and use due to the need for charging, and sometimes even rechargeable batteries will cause unsafe factors; therefore, how to solve the above problems has become an urgent problem to be solved.

Utility model content

The technical problem to be solved by the utility model is to provide a far-infrared heating insole with long service life, good heat preservation effect, long time, good air permeability, easy to use, not easy to damage and high safety for the above-mentioned shortcomings of the prior art. .

In order to solve the above-mentioned technical problems, a far-infrared heating and warming insole of the present invention includes an insole body, and the insole body includes a middle heat transfer sponge, a cortex layer arranged on the upper surface of the middle heat transfer sponge, and an inner layer arranged on the middle heat transfer sponge. The nylon cloth on the lower surface, the heat transfer sponge in the middle is provided with a heating device, and the heating device includes a battery connected in sequence, an electrical connection switch, a charging circuit and a heating sheet.

In the above-mentioned far-infrared heating and warming insole, the charging circuit is provided with an electrical connection plug to connect to an external circuit.

In the above-mentioned far-infrared heat-retaining insole, the heat-generating devices are all electrically connected circuits and are configured as an integral structure.

After the utility model adopts the above-mentioned structure, an intermediate heat transfer sponge layer is arranged in the insole to ensure the overall softness of the insole, and the user feels very comfortable when wearing it, and the sponge has the characteristics of heat preservation and ventilation, which effectively ensures Warm and breathable effect; by setting the battery as an explosion-proof battery of 1100 mAh, and the specified current is 3.7 volts, the safety of the battery during charging is ensured, and the battery used can use 3 to 5 batteries at a time when the power is saturated. hour, which ensures that users can use it outdoors. This kind of battery can withstand a pressure of 90 kilograms, and the entire insole device will not be damaged due to weight problems, which greatly meets the needs of more consumers and ensures that the insole Longer service life.

The utility model will be further described in detail below in conjunction with the embodiments in the accompanying drawings, but this does not constitute any limitation to the utility model.

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the utility model sectional structure schematic diagram;

Fig. 3 is a structural schematic diagram of the heating device of the present invention.

Among the figure: insole body 1, intermediate heat transfer sponge 2, cortex 3, nylon cloth 4, heating device 5, battery 51, switch 52, charging circuit 53, heating sheet 54, plug 55.

Detailed ways

As shown in Figures 1 to 3, a far-infrared heating and warming insole of the present invention includes an insole body 1, and the insole body 1 includes an intermediate heat transfer sponge 2 and a cortex layer on the upper surface of the intermediate heat transfer sponge 2. 3 and the nylon cloth 4 arranged on the lower surface of the intermediate heat transfer sponge 2, wherein the intermediate heat transfer sponge 2 is provided with a heating device 5, and the heating device 5 includes a battery 51 connected in sequence, an electrical connection switch 52 , charging circuit 53 and heating sheet 54.

The charging circuit 53 is provided with an electrical connection plug 55 to connect to an external circuit.

The heating devices 5 are all electrically connected circuits and are configured as an integral structure.

When the utility model is actually used, a layer of intermediate heat transfer sponge 2 is arranged in the insole to ensure that the user is soft and comfortable when wearing the insole, and the overall softness of the insole is guaranteed. Because the sponge has the characteristics of heat preservation and ventilation, it is arranged on the insole The interior can also ensure breathable and warm effects, and users feel more relaxed and comfortable when exercising or walking outdoors; the battery is an explosion-proof battery of 1100 mAh, and the specified current is 3.7 volts, which ensures the safety of the battery during charging , and the user can use it for 3 to 5 hours at a time when the battery is saturated, which ensures that the user can use it outdoors for a long time. The entire insole device is destroyed, which greatly satisfies the needs of more consumers and also ensures that the insole has a longer service life.

In summary, the utility model has been made into actual samples according to the contents of the instructions and illustrations and has been tested for a long time. Judging from the effect of the test, it can be proved that the utility model can achieve its expected purpose, and its practical value is worthless. Doubt. The above-mentioned embodiments are only used to illustrate the utility model for convenience, and are not intended to limit the utility model in any form. Anyone with ordinary knowledge in the technical field, if not departing from the scope of the technical characteristics of the utility model , Equivalent embodiments made with partial changes or modifications using the technical content disclosed in the utility model, and without departing from the technical features of the utility model, all still fall within the scope of the utility model's technical features.
