Abstract

The utility model relates to a low-voltage electric-heating footwear, composed of a common footwear body, a resistance wire with low resistance ratio arranged at the front part of a sole, a plug in a footwear heel, a wire connected with the resistance wire through the sole and the inner part of the footwear heel and a buckle cover on the footwear heel; a heat insulating footwear pad is arranged in the footwear which is matched with a common power source box with low-voltage. The utility model has the advantages of safety, saving electricity, good using effect, convenience and no limitation in place, and can keep the appearance of the common footwear.

Description

Low-voltage electric-heating footwear

The utility model belongs to the footwear technical field.

Existing electric heating shoes adopts wooden, directly adopt 220 volts of city's electrical heating, its footwear body seriously breaks away from the outward appearance and the heavy inconvenience walking of shoes, can only when heating, pin be penetrated wherein temporarily, change loaded down with trivial detailsly, in a single day the footwear body breaks or makes moist, and 220 volts of voltages will directly threaten personal safety, and generally all more than 20W, power consumption is big for the heating resistance wire that adopts.

The purpose of this utility model is to provide a kind of outward appearance to keep the city shoe style, and that indoor and outdoor is used is unrestricted, adopt low-voltage power supply, the low pressure electrically warmed shoe of safe in utilization, convenient, power saving.

The technical solution of the utility model is: the special character of this low pressure electrically warmed shoe is that it is by the various city shoes of city shoe body 1(), place footwear body 1 sole forepart (at the minimum position of human body temperature---toe and sole forward position local heat, thereby reach energy to economize most, minimum cost reaches the antifreeze effect that heats up) resistance wire 6, build-in in the various common double line sockets of the socket 4(of footwear body 1 heel inboard all can), be connected in inboard also common the buckle cover 3(of housing on socket 4 of heel and can be the band button, the hinge button, the plastic sheet of Simple zipper etc., sheet rubber, cloth sheet etc., in case Buddhist nun, sand enters in the socket), form through sole and the inner plain conductor 5 that connects resistance wire 6 and socket 4 of heel, resistance wire is 20-30 Europe, the shoes operating voltage is that the 6-20 volt (adopts low-voltage, small-power, at the main position heating of human body sole, so safety, power saving, heat effective).

Special character of the present utility model also is also to be lined with on footwear body 1 insole common heat insulating mattress 2(of sole-shaped and can be heat-barrier material pads such as asbestos, glass fibre, and thickness is fixed according to needs) so that still can be incubated for a long time after the shoes outage.These shoes also are furnished with the common many grades of output low-tension supplies with 1 split of footwear body, its output be connected to heel on the plug that is used of socket, output voltage is the 6-20 volt; Can insert on the shoes socket during use easily and heat up, can select voltages according to various ambient conditions, and can be when the beginning preheating with high pressure, the back of heating up with the low pressure insulation, guarantee not only warm but also power saving; When not using, can take in the portable package, easy to use.

Fig. 1 is the utility model cross-sectional schematic;

Fig. 2 is the utility model sole cross-sectional schematic;

Fig. 3 is the utility model low-tension supply embodiment circuit diagram.

Further set forth embodiment of the present utility model below in conjunction with accompanying drawing:

As Fig. 1,2, shown in 3, this low pressure electrically warmed shoe is by city shoe body 1, place 24 Europe resistance wires 6 of footwear body 1 sole forepart, build-in is in the common cylindricality socket 4 of footwear body 1 heel inboard, be connected in the inboard also common easy-to-draw locking plate of housing on socket 4 of heel and buckle cover 3, through sole and the inner plain conductor 5 that connects resistance wire 6 and socket 4 of heel, fill up the outer infantees of the thick asbestos shoe-pad of 4mm 2(on footwear body 1 insole), (output voltage is 6 to split type 3 grades of power transformers, 10,15 volts, among Fig. 3: R1 200K Ω resistance, the L250V neon bulb, B 6W3 tapped transformer, K SP3T switch, RL---24 Ω resistance wires 6).

During use, directly these footwear are through at and do the conventional shoe use on the pin.When needing heating, open the button cover 3 of heel medial surface, low-tension supply one end is inserted socket 4, the other end inserts commercial power socket, and the footwear internal resistance wire will heat up under the voltage effect and heat toe and sole front portion, reaches warm pin and antifreeze effect.Little because of resistance wire resistance, the shoes operating voltage is low, so safety, power saving, temperature can be too not high and bathe one's feet in hot water.When not heating, power pack two ends plug is taken off, button cover 3 gets final product on the good heel of buckle closure, and is easy to use.

The utlity model has that safety, power saving, result of use are good, convenient, indoor and outdoor uses unrestrictedly, keeps the advantage of conventional shoe style.

Experimental result (resistance wire 24 Europe, with common cloth shoe-pad, shoe insole surface has covering) when following table is 0 ℃ of an ambient air temperature.

Resistance wire both end voltage (V)	Heating-up time (branch)	Shoe insole surface temperature ℃	Every pair of footwear power consumption (W)
				6	3	14	1.5
10	6	22	3.6
				15	14	28	6.8
