Abstract

The utility model relates to a low-voltage temperature controllable AC electric-heating shoe-pad, comprising a shoe pad, an electric heating wire arranged in the shoe pad, a connecting assembly, a power transformer and a temperature switch with different gears. The utility model is characterized in that the secondary winding of the power transformer is provided with a plurality of taps to provide the voltage with different values, and the power transformer is matched with the temperature switch with different gears to provide the electric heating wire with the voltage with different values. The utility model only uses low voltage in the shoe pad, and thus the shoes are worn safely; the heating power and the heating temperature can be adjusted into different states according to the user's needs; the utility model is worn comfortably and can save electric energy. When the moving distance is over the length of the wire, the plug of the electric heating shoe can be pulled out for the user walking conveniently without taking off the shoe.

Description

Low-voltage temp. controllable AC electric-heating shoe-pads

The utility model relates to a kind of adjustable electric heating shoe pad of AC low-tension that has electric heater unit of using in the daily life.

In recent years, electric heating shoe-pad (electric heating shoes) begins to obtain people's attention and employing because of it has the advantage that cost is low, power consumption is little, individual heating effect is good, and is wherein more economical and practical to use electric main to make the electric heating shoe-pad (electric heating shoes) of power supply again.But following still unsatisfactory problem is, in numerous this type electric heating shoe-pad (electric heating shoes) products or patent application design, electric main has directly been introduced shoe-pad (footwear) inside, so just caused dangerous in the electricity consumption.Having notification number only is CN2123902U " electric heating shoe-pad ", then take electric main is introduced within the shoe-pad after the transformer step-down becomes safe voltage again, so it has the sense of security in the use.Yet be that this electric heating shoe-pad can not come stepping to regulate the temperature height according to user's needs to what it still felt blemish in an otherwise perfect thing.

The purpose of this utility model is that a kind of adjustable electric heating shoe pad of AC low-tension that can come stepping to regulate the temperature height according to user's needs is provided.

Solution of the present utility model is as follows.Connector assembly that it still includes shoe-pad, be contained in heating wire in the shoe-pad, link to each other with heating wire by lead and the power transformer that has attaching plug, and its feature part is, the secondary winding of power transformer has a plurality of taps that many group voltages can be provided, also have in addition by lead respectively with a plurality of taps of power transformer secondary winding and the stepping temperature regulating switch that links to each other with connector assembly.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the embodiment of a kind of concrete structure of the utility model;

Fig. 2 is the electrical schematic diagram of Fig. 1 the utility model embodiment.

Referring to Fig. 1 and Fig. 2,1 of the shoe-pad among Fig. 1 shows right shoe-pad, and the structure of left shoe-pad is identical, so save.Shoe-pad 1 is by the asbestos cloth that mediates 11 and be in asbestos cloth 11 outer multilayer cottons 12 and make and form, heating wire 2 right bend alignment are fixed between the two-layer asbestos cloth 11, two terminations on heating wire 2 right sides link to each other with the socket 41 of connector assembly 4 by lead 3, the elementary winding of power transformer 5 is connected to attaching plug 7 by lead 6, the secondary winding of power transformer 5 has three taps, stepping temperature regulating switch 8 adopts double-point double-throw switch, be installed on the shell of power transformer 5, link to each other with three taps of transformer 5 secondary winding and the plug 42 of connector assembly 4 respectively by lead 9.When attaching plug 7 connects the 220V electric main, respectively double-point double-throw switch 8 is invested " fast heat " and " constant temperature " two different gears, then power transformer 5 can provide the low pressure of two groups of different sizes below the 15V to heating wire 2 right sides and 2 left sides, to form the electrical heating powers of different sizes.Test shows that the adult uses electric heating shoe-pad, carries out " fast heat " with the 15W power consumption, can reach the needed temperature of people in 1.5 minutes, then can keep " constant temperature " with the 7.5W power consumption.Child is no more than 10W with the electric heating shoe-pad power consumption.According to the length of power consumption and shoe-pad, select suitable heating wire diameter and length, make the heating wire surface temperature be no more than 80 ℃, to guarantee not burn out shoe-pad.Power transformer secondary winding of the present utility model also can adopt more than three taps, increases the temperature adjustment gear of stepping temperature regulating switch simultaneously.The low-voltage that provides to heating wire is as long as all can below the 36V human safety voltage.

The utility model is just introduced shoe-pad inside with low pressure, and is therefore safe and reliable, and its heating power and heating-up temperature can be carried out stepping according to user's needs and be regulated Energy and comfort, and saving electric energy.Shoe-pad adopts connector assembly with being connected of power transformer, when the distance of walking about surpasses conductor length, can pull up the plug of electric heating shoe-pad, and the user need not take off one's shoes and walk conveniently.

Claims

1, the adjustable electric heating shoe pad of a kind of AC low-tension, connector assembly that includes shoe-pad, is contained in heating wire in the shoe-pad, links to each other with heating wire by lead and the power transformer that has attaching plug, it is characterized in that, the secondary winding of power transformer has a plurality of taps that many group voltages can be provided, also have in addition by lead respectively with a plurality of taps of power transformer secondary winding and the stepping temperature regulating switch that links to each other with connector assembly.

2, electric heating shoe-pad as claimed in claim 1 is characterized in that, the secondary winding of power transformer has three taps, and the stepping temperature regulating switch adopts double-point double-throw switch.
