Abstract
The positive temperature coefficient electric heating ceramic constant temperature electric heating bag is characterized in that: the two electrodes of the electrothermal ceramic are respectively connected with two contact brass electrodes, the yellow wax silk insulator covers the brass electrodes, and the leads of the two brass electrodes respectively penetrate through the wooden frame holes to be connected with one ends of the fuse and the temperature relay.
Description
This utility model belongs to the articles for daily use.
The local heating system of the household person of selling mainly contains electric warming pad, hot-water bag, chemical hand warmer etc. in the market, and the said goods is domestic prior art.
Though electric warming pad has certain physiotherapy function to diseases such as chronic arthritis, nephritis, gastropathy, rheumatism hemorrhoid, be afraid of folding, generation magnetic field but there is, can not be temperature automatically controlled and cause body water to evaporate in a large number, cause that mouth and nose are dry, bring out skin allergy, make that the people is fed up with, shortcoming such as weak, fidgety.Though hot-water bag does not produce magnetic field, owing to need the manufacture hot water before using, exist initial stage temperature height simultaneously, become cold bag after 3--4 hour, can not keep homothermic shortcoming continuously.The chemistry hand warmer then exists and need to change chemical drugs, easily shortcoming such as pollutes.
The purpose of this utility model is to provide a kind of relatively safety, the local heating system of ideal household person, and is folding to solve the electric warming pad fearness that exists in the prior art, produces magnetic field, can not be temperature automatically controlled; Before using, hot-water bag needs the manufacture hot water, initial stage temperature height, temperature retention time weak point; The chemistry hand warmer shortcomings such as inconvenience and pollution of changing dressings.
Design of the present utility model is: it is made up of positive temperature coefficient electric ceramic, brass electrode, insulating varnished silk, wooden frame, temperature relay, fuse, power line, cover plate, cotton blanket heat-storing material, polrvinyl chloride waterproof jacket, decoration woollen blanket cover, switch assembly, plug; Make the heating core body with electric ceramic, electric ceramic the two poles of the earth are connected with two contact brass electrodes respectively, the insulating varnished silk insulator covers the brass electrode outside, two brass electrode lead-in wires pass the wooden frame hole respectively and are connected with temperature relay one end with fuse, the temperature relay other end is connected with another fuse again, two fuse other ends are connected with bifilar power supply lead wire respectively, behind the access switch assembly, are connected with plug by the switch assembly extracting power supply cord again; Electric ceramic, brass electrode, insulating varnished silk insulator, temperature relay, fuse are packed in the wooden frame lattice, nail on the plywood cover plate of band louvre up and down, put the cotton blanket heat-storing material again, put the polrvinyl chloride waterproof jacket, put again and decorate the woollen blanket cover, become the local heating system of flexible bag-like individual after the stitching.
This utility model compared with prior art, its advantage is: because design pouch profile, and coat flexible woollen blanket, cotton blanket heat-storing material, similar to traditional hot-water bag, make the people be easy to accept, do not produce magnetic field, harmless, decoration woollen blanket outside is provided the towel cover for oneself by the user and can be changed washing at any time, does not have the skin cross infection.Because can be temperature automatically controlled, heater element appearance maximum temperature be lower than 60 ℃, not only help to the body local disease keep healthy, physical therapy, hot compress, be again simultaneously the equipment of the warm hands of northern old people, warming the stomach, warm foot; In order to prevent that electric ceramic from burning because of the qualitative factor part, make that electric current is excessive, temperature is too high and work the mischief, established the fuse and the JW of the different blowout currents of twice
7-3-60 ℃ of temperature relay makes it safe and reliable, scalds and fire to prevent.
Figure of description:
Fig. 1 is positive temperature coefficient electric ceramic constant temperature electric heating bag constructions figure, wherein: 1, towel overcoat; 2, decorate woollen blanket; 3, polrvinyl chloride waterproof jacket; 4, accumulation of heat cotton blanket; 5, plywood cover plate; 6, wooden frame; 7, electric ceramic; 8, brass electrode, 9, insulating varnished silk insulator;
Fig. 2 is the internal structure wiring diagram, wherein: 10, fuse; 11, JW
7The type temperature relay; 12, power line;
Fig. 3 is an electrical schematic diagram, wherein: 13, switch assembly; 14, attaching plug.
Circuit theory is: circuit is connected after-current by the plug switch assembly of flowing through, and one the tunnel through overcurrent fuse RD1, K switch, resistance R and LED, K switch, fuse RD4Get back to power supply and do the energising indication: fuse RD flows through on another road1, K switch, fuse RD2，JW
7Type temperature relay, electric ceramic, fuse RD3, K switch, fuse RD4Get back to power supply and do the heating heating; When the electric ceramic temperature reached 55 ± 5 ℃, it is infinitely great that resistance value is, and electric current levels off to zero, if when electric ceramic had puncture to wait fortuitous event, temperature surpassed 60 ℃, JW7The type temperature relay is cut off the electricity supply and is the protection state.
Most preferred embodiment of the present utility model is: it is as the heating core body by electric ceramic (7); Contact brass electrode (8) in addition up and down; Again coated with insulating varnished silk insulator (9); Pack in the wooden frame (6); Nail has the plywood cover plate (5) of band louvre up and down; The outside coats cotton blanket heat-storing material (4); Put polrvinyl chloride waterproof jacket (3); The outside coats and decorates woollen blanket (2) again; Outermost is towel cover (1); The lead-in wire of electric ceramic passes wooden frame and joins with fuse (10) and temperature relay (11), joins with power line (12) again; Power line joins through switch assembly (13) and plug (14).
