Abstract
The utility model relates to an automatic temperature control infrared health electric heating rug, comprising an electric blanket, an upper layer (1), a lower layer (2), heating wires (3), and a temperature control system (5). The bottom surface of the electric blanket upper layer (1) is sprayed with a far ultrared paint (12); the temperature control system (5) is additionally provided with a comparator (6), and the first input end (13) is connected with a temperature sensor (7). The utility model transmits the temperature signal to the comparator (6) through the temperature sensor (7), and the output signal controls the attraction of a relay after comparison. The scheme solves the defects that the existing electric blanket only has a high and a low temperature and can not randomly control the temperature, and the utility model is additionally provided with a far infrared medical care efficacy.
Description
The utility model relates to the temperature control system and the structural improvement of electric blanket.
In the prior art, electric blanket adopts a diode to make halfwave rectifier usually, has only the branch of high and low temperature second gear, temperature can not arbitrarily be controlled, in different regions, Various Seasonal, it is overheated that the high temperature shelves are often appearred in the different people of health condition, low temperature shelves phenomenon such as temperature is not enough again.
In view of the deficiency that prior art exists, the utility model aims to provide a kind ofly can regulate the electric blanket of temperature automatically according to the human body needs; Another purpose of the present utility model is that the far infrared medicinal health care function is provided in warming.
The utility model is realized in the following ways.The utility model comprises (1) on the electric blanket, following (2) layer, heating wire (3), attaching plug (4), temperature-controlling system (5), spray red coating far away (12) in the bottom surface of electric blanket upper strata (1), in temperature-controlling system (5), have additional first (13), the comparator (6) of second (14) input and an output (15), first input end (13) in described comparator (6) connects temperature sensor (7), the potentiometer (8) and variable resistor (9) that connect series connection at described second input (14), the base stage (16) that connects transistor (10) at described output (15), collector output (17) in transistor (10) connects relay (11), by temperature sensor (7) temperature signal is sent to comparator (6) and compares, the adhesive that comes control relay (11) by the signal of output after relatively.
The utility model has compared with prior art solved the difficult problem that different regions, Various Seasonal, the different selected warming temperature of personal health condition have nothing in common with each other, simultaneously a large amount of conserver power source, and play medical care effect.
The utility model has following accompanying drawing
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is a sectional side elevation of the present utility model
Fig. 3 is temperature-controlling system circuit theory diagrams in the utility model
Accompanying drawing has been represented structure of the present utility model and principle thereof, is further elaborated in conjunction with the embodiments more below.The utility model comprises go up (1) of electric blanket, following (2) layer, heating wire (3), attaching plug (4), temperature-controlling system (5), be coated with far ultrared paint (12) in the bottom surface of electric blanket upper strata (1), in temperature control system (5), have additional first (13), the comparator (6) of second (14) input and an output (15), and by negative thermistor (7), potentiometer (8), variable resistor (9), resistance R 1, the measuring bridge that R2 forms, first output (13) at described comparator (6) connects negative thermistor (7), second input (14) connects the potentiometer (8) and variable resistor (9) of series connection, its output (15) connects the base stage (16) of triode (10), the collector output (17) of triode (10) connects relay (11), variation by negative thermistor (7) sensible temperature, and signal is transported to comparator (6) compares, by the adhesive of the signal control relay (11) of output after relatively.AC power 220V is through power transformer (18), obtaining the 12V direct current after bridge rectifier (19) voltage stabilizing uses for comparator (6) and triode (10), regulate variable resistor (9) and can reach adjusting electric blanket holding temperature, when electric blanket temperature does not reach temperature required, first input end (13) voltage of comparator (6) is higher than the voltage of second input (14), then comparator (6) has positive voltage output, triode (10) conducting, relay (11) winding has electric current to pass through, then relay (11) adhesive, be that J2 contacts with J3, heating wire (3) conducting heat temperature raising, at this moment red led (20) is bright, when the temperature of electric blanket reaches required adjusting temperature, measuring bridge reaches balance, the no positive voltage output of comparator (6), then not conducting of triode (10), relay (11) not adhesive of dead electricity, be that contact J2 contacts with J1, heating wire (3) no current passes through, and at this moment electric blanket keeps constant temperature, and green indicating lamp (21) is bright.One deck far ultrared paint (12) in the spraying of the bottom surface, upper strata (1) of electric blanket raises and is absorbed by the body along with electric blanket temperature simultaneously, far ultrared paint by oxide and clay, water mixing stirring, pulverizing, high temperature burn red, pulverize and form again, described oxide can be multiple oxides such as zirconium dioxide, titanium dioxide, chromium dioxide, manganese dioxide, iron oxide, it plays sterilization, relaxes the muscles and stimulate the blood circulation, eliminates effects such as fatigue human body, particularly to lumbar muscular injury, diseases such as arthritis have special curative effect.The utility model collection temperature automatically controlled with health care be one, be the warming desirable articles for use of passing the winter during people live.
