Abstract
The utility model is a new electric heating appliance-multifunctional electric heating pad. It is composed of insulating and heat-resisting rubber material and heating element. It has excellent electric safety performance and temperature performance. It has multiple purposes, not only can be used as a household electric heating, physical therapy and drying appliance, but also can be used as an ideal appliance for heating and physical therapy in hotels and hospitals. The industrial heater can be used as a heater of an automobile battery, and can improve the capacity of the battery during freezing prevention and engine starting. A magnetic electric heating pad is pasted below the automobile oil bottom to heat the engine oil, so that the engine is easy to start. The electric heating pad using 6-24V DC power supply can be used for warming the driver in winter, improving the driving condition and preventing accidents.
Description
The utility model relates to a kind of multifunctional electro-heating pad, particularly the multifunctional electro-heating pad made from insulation, heat resistant rubber or magnetic rubber material, heater element.
The electric blanket of Xiao Shouing generally all adopts cotton, cotton blanket to make lining in the market, and insulating varnished silk etc. are as insulating barrier; The electric blanket that heater element adopts polyvinyl chloride wire or nichrome wire etc. to make, though done insulation processing,, started slow (surface temperature was 15 ℃ in 30 minutes), must fold when depositing because area is big, insulated wire is subjected to reasons such as heat ageing, and the electric leakage accident happens occasionally.And bad cleaning, purposes is also single.
The purpose of this utility model just is to produce a kind of multifunctional electro-heating pad, and it serves many purposes, and good electrical safety performance and temperature performance (starting 40 ℃ of fast 3-5 minute surface temperatures) are arranged.Promptly can be used as family's electric heating, physiotherapy, oven dry utensil, can supply hotel, hospital again as heating, lagging facility and physiotherapy apparatus.Going on business, travel, it is also convenient to carry.
Industrial can be as the automobile storage battery heater, pad is placed on below the storage battery and improves the storage battery capacity when being shockproof antifreeze again and engine start.Face pastes a magnetic electrothermal pad heating machine oil under automotive oil, makes engine be easy to start.Use the electric pad of 6-24 volt DC power supply, heating in driving a vehicle in the winter time for the driver improves riving condition, and the accident that prevents takes place.
The utility model is a kind of Multifunction electric pad, and its structure is shown in accompanying drawing 1 plane graph, Fig. 2 profile: (1) is insulation, heat resistant rubber layer, (2) heater element, (5) temperature control switch, (6) rivet, (7) lead, (8) plug.The utility model adopts two layers of insulation, heat-resistant rubber slab heater element to be bonded in middle.
The elastomeric material that the utility model adopts has: non-polar rubbers such as butyl rubber, silicon rubber, natural rubber, thermoplastic elastomer (TPE), select low structure filler vulcanizing system for use.Heater magnetic rubber plate adopts neoprene or natural rubber at the bottom of the automotive oil, selects for use strontium iron powder, aluminium ferronickel powder, iron barium powder etc. as filler.Magnetic rubber plate inner surface is done insulation and is handled, and selects 402 chloroprene rubber adhesive agents (production of Beijing adhesive two factories) for use, or 704 silicon rubber (production of Condar chemical plant, Liyang) etc. are as coating.See accompanying drawing (3).The insulation property of the rubber that the utility model adopts see Table (1).
The specific insulation of table 1 rubber
| Rubber clone | Specific insulation Ω cm |
| Natural | 10 14-10 15 |
| Butyl | 10 15-10 16 |
| Neoprene | 10 10-10 12 |
| Silicon | 10 15-10 17 |
Heat-resisting, the cold resistance of the rubber that the utility model adopts see Table (2).
The thermal endurance of table 2 rubber and cold resistance
| Rubber clone | Maximum operation (service) temperature ℃ | Temperature upper limit commonly used ℃ | Brittleness temperature ℃ |
| Natural | 120 | 70～80 | －50～－70 |
| Butyl | 170 | 150 | －30～－55 |
| Neoprene | 150 | 120 | －35～－42 |
| Silicon | 315 | 200 | －70～－120 |
It is a kind of heating plate made from constantan wire and polyimide film (being applicable to 6～24 volts of direct currents) that the utility model heater element is selected from enamelled wire (being applicable to 50 volts of alternating currents), nichrome wire and Aludirome silk (being applicable to 220 volts of alternating currents), film heating plate.
The utility model external form is fit to make rectangle, and its length and width ratio can change according to different purposes, also can make garden shape, annular.Electric pad can overlap a cotton jacket when using, and also can directly use.The suede processing can be sprayed in the surface, sees accompanying drawing (4).The spray down material is selected cotton, fiber crops, hair, blending lint etc. for use.Through the electric pad that spray suede is handled, temperature retention time is long, good hand touch.
The utility model temperature control method selects for use capacitor charge and discharge temperature control, bidirectional triode thyristor adjuster temperature control, 3～5 grades of manual temperature controls of temperature regulating switch, temperature relay temperature automatically controlled, (more than be applicable to 220 volts of alternating currents).Transformer plugs low pressure temperature control (being applicable to 50 volts of alternating currents) industrially can not established the temperature control switch.
