Description
Technical field
The present invention relates to electric heating technical fields, more particularly to one kind not only can ensure that user's absolute safety but also can expire
Sufficient human body different zones are to realizing temperature controlled intelligent and safe electric blanket and heating means on the basis of temperature requirements.
Background technique
Common electric blanket is a kind of contact electric heating appliance, and insulation performance is reached the special soft of certain safety standard by it
Cable-styled heating element is woven into disk serpentine or sews up in woollen blanket, and when energization can produce heat appropriate, generated heat some
It is that equilibrium is constant, there are also some controllable adjustables.
Different electric blankets has the characteristics that respectively to protrude, for example, in power consumption, temperature adjusting, degree easy to use, use
Range, durability etc. have certain novelty.
Reach in view of people using the most basic original intention of electric blanket is mainly the temperature in sleep raising quilt
Heating purpose, certainly, it may also be used for bedding removes moisture dehumidifying, and safety becomes the prerequisite item for manufacturing various different characteristics electric blankets
Part, some Special use groups, for example, pregnant woman, children, old man etc. can electric blankets safe to use.
The safety of electric blanket is mainly reflected in radiation safety, power safety, temperature safety at present, is ensuring these safety
On the basis of performance, electric blanket can be made to play its advantages to the full extent, for example, there is good guarantor to the people for having rheumatism
Shield effect and the chance that can reduce its breaking-out, for another example, to old man or the special weakling of constitution, electric blanket, which also can provide, to be compared
Good care.
Although the further research and development to electric blanket can play the above advantage, problem is also following, for example, if electricity
Hot blanket sole mass is not up to standard, is likely to that there is a phenomenon where leak electricity after prolonged use;It is obtained if temperature is higher always
Less than the control of different demands, then people's internal water and salinity are obviously lost, and are easy to appear dry, pharyngalgia, nostril bleeding, skin
Dry and constipation etc.;It is extremely wide to the health effect of human body if the electromagnetic radiation of electric blanket is stronger, Chang Huiyin
People's heart rate is played, blood pressure raising, accelerated breathing, wheezes, perspire;If the physical vigor of children is bigger, and uncomfortable electricity
The suitable temperature of hot blanket, can make child decline cold resistance, and immunity can also decrease;In addition, for electric blanket
Harm be also manifested by the excessively high quality that can reduce sleep of temperature, lassitude after making get up for second day;It heats up according to machinery,
The balancing of human body can be destroyed, so that blood pressure be promoted to increase.
Those skilled in the art have carried out analysis using many experiences of electric blanket according to family and have found:
The unsafe factor of electric blanket is caused to specifically include that the blanket body electrification 220V alternating current of most of electric blankets directly and people
Body contact, thus there is electric shock hidden danger;Simultaneously as electric blanket device ac capacitor is also easy to produce alternating magnetic field, it is used for a long time
Human health can be generated harmful;
On the basis of not having higher-security energy, electric blanket is caused to be unable to satisfy the factor packet of human body use demand
Include: since mechanical temp controlled mode is simple, being unable to satisfy different use groups, human body whole night makes the different demands of temperature, difference
With the various demands such as environment;Meanwhile existing some low-voltage electrical heating blanket product temperature control methods are then damaged according to components such as linear switches
Consumption is big, and there is response speeds it is slow, control precision is low, human-computer interaction is poor the disadvantages of.
In conclusion the present invention is exactly on the basis of existing well-known technique, in conjunction with the verifying of practical application, to same skill
Product structure in art field proposes that the technical solution further researched and developed with designed, these technical solutions proposed are entirely capable of solving
Problem certainly of the existing technology, while being also beneficial to the solution of numerous technical problems of same technical field and developing skill
