The purpose of this utility model is to overcome the deficiencies in the prior art, aims to provide a kind of thermal effect height, and is easy to carry, safe in utilization, and the electric heating product series spare of the totally-enclosed maintenance-free storage battery composition of Pb-Ca-Al alloy electrode is grown and had to the life-span.
The utility model electric heating product series spare comprises the electric heating product spare of making clothes, footwear, cap, quilt, cotton-padded mattress, pad, baby's constant temperature insulating bag, shoulder protector, gloves, waistband, stomacher, knee-pad, socks and electric heating constant temperature sleeve-like; voltage range is in the DC power supply of 1.8V-6.3V; connect with power line; in order to reach the optimal heat effect; specially use electric heating element in electric heating product spare, it comprises metal wool, screening glass and the heating wire of being made up of following composition (percentage by weight):
Ag：3－5％，Si 0.1－0.15％，Mg：0.01－0.1％，Mn：0.2－0.8％，
C:0.05-0.1%, rare earth: 0.2-1.2%, surplus its is Ni.Heating wire is made sewer on metal wool, and screening glass is attached to the outside of the metal wool part with heating wire, and electric power connection line then is connected with heating wire by screening glass.
The various body heating that the utility model is made is incubated articles for use, the thermal effect height, long service life, beyond safe and reliable, wear comfortablely, in light weight in addition, can repeatedly wash, but the wearing DC power supply portably uses all day with oneself, and some disease is had the certain supplemental treatment and the function of health care.Simple in structure, make producing conveniently, with low cost.
In order to introduce the utility model in detail, be introduced below in conjunction with accompanying drawing:
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is an electric heating product spare cutaway view of the present utility model;
With reference to Fig. 1, the utility model is by battery 1, electric power connection line 2, and the heating 3 in the electric heating product spare 4 forms various serial body heating's thermal insulation articles.
Battery 1, be a kind of battery with Pb-Ca-Al alloy electrode, a kind of energy that is inventor's utility model of declaring on December 8th, 90, application number 902255495 is big, in light weight, volume is little, need not regular maintenance, the battery of totally-enclosed, the special-shaped shell that is particularly suitable for special occasions, this battery can be accomplished the rapid lapse of time so of a year and a half at least Non-maintaining, voltage is at 1.8V-6.6V. The invention of this battery is that the utility model has been established important foundation.
Electric power connection line 2, with direct-current power supply heating 3, this silk is nickel alloy wire, and fuel factor is fabulous, belong to positive polar filament, when temperature is elevated to certain limit, resistance value just increases, and has good thermostatic characteristics, this heating wire middle rare earth composition is take the rare earth element of cerium (Ce) as one or more main any combination, this wire diameter is between 0.2-0.4mm, and wherein take 0.25mm as good, succeeding in developing of this plays a part crucial for invention of the present utility model.
With reference to Fig. 2, anti-bacteria cloth A is a kind of fabric with antibiotic odour repellent function, is a patented product that obtains Jiangsu Province's new product Taurus prize, and this product is applied to the utility model, plays health care. Metal wool B is that the benefit people in Shanghai pack the patented product of equipment factory, is a kind of Novel heat-preservation inner lining material, it be the reflex of utilizing metal level with heat again radiation turn back on the human body, make warming and heat insulation effect of the present utility model better. This product obtains State Scientific and Technological Commission's 90 annuity arrows prize.
