Abstract
The utility model discloses a rechargeable electric heating blanket which mainly comprises a blanket (1), a heating element (2) and an electric device control box (3). The utility model is characterized in that the heating element (2) comprises the carbon fiber electrothermal wire in curved shape or random shape distributed between the interlayer of the blanket (1), or the carbon fiber electrothermal cloth formed by directly braiding with the fiber on the surface of the blanket. Two outgoing lines of the heating element (2) are accessed to the electric device control box (3). The utility model has better suppleness and higher electric heating conversion efficiency. The rechargeable electric heating blanket with automatic protector and wide application range can automatically control the temperature and is not limited by the power supply, being especially suitable for people who are in field operation to sleep and get warm at night.
Description
Affiliated technical field
The utility model relates to a kind of rechargeable AC/DC electric blanket.
Background technology
The electric blanket that people use traditionally mostly uses metal heating line, is with dielectric film in its outside and makes the heating line.But because the heater of its use is made by metal material, flexibility is undesirable, frangibility, easily aging, electric conversion efficiency is low, uses power supply to be High Level AC Voltage simultaneously, and the electric current spark is easily arranged during switch, security performance is relatively poor, can't use under the situation of alternating current.
Summary of the invention
The purpose of this utility model provides that a kind of softness is good, low-voltage safety, power saving, easy to use, can A.T.C and the rechargeable AC/DC electric blanket that can use in the open air.
In order to achieve the above object, technical solutions of the utility model are: mainly comprise blanket, heater and electric appliance control box, described heater comprises the carbon fibre electrothermal wire that is distributed in curved shape between the blanket interlayer or arbitrary shape or the carbon fiber electric heating cloth that directly forms with the braiding of blanket surface fiber, two lead-out wires access electric appliance control boxes of described heater.
The blanket fiber surface of described electric heating cloth and carbon fibre electrothermal wire are broadwise and radially or radially form with broadwise or oblique crossing braiding.Described electric appliance control box is provided with control switch, charging socket, supply socket, is provided with high power capacity rechargeable battery, automatic constant-temperature and automotive quick-heat system, automatic battery monitoring system in the electric appliance control box.
The utility model is owing to adopted carbon fibre to make heater, and be provided with automatic control system, its heater can be the heating line, making between lining material and lining, also can be electrothermal cloth, directly as lining, have softness and higher electric conversion efficiency preferably, electric conversion efficiency is higher by 30% than metallic heating body, and with the water phenomenon that is not short-circuited, can not cause short circuit or electric shock phenomenon because of situations such as child's enuresis.Owing to be provided with automatic constant-temperature and automotive quick-heat system in the electric appliance control box, can keep guaranteeing in temperature constant and the utmost point cold environment heating up continuously in a few minutes reaches the temperature that sets.Warning was sent in shutdown automatically simultaneously when cell voltage was not enough, reminded the user in time to change battery, to guarantee the useful life of battery.Control box is provided with external power supply and charge power supply socket, is convenient to external power supply and battery charge.
The utility model provides a kind of softness good, the electric conversion efficiency height, and low-voltage safety, the power and energy saving, easy to use, AC/DC electric blanket that can A.T.C is applicable to family's sleep in winter heating, is more suitable for the field work personnel needs of warming oneself evening.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the electric blanket structural representation that carbon fibre electrothermal wire and the braiding of blanket surface fiber form.
Among Fig. 1, electric blanket 1, heater 2, electric appliance control box 3, power control switch 4, charging jack 5, supply socket 6.
Embodiment
According to a kind of rechargeable electric blanket shown in Figure 1, between its lining or blanket 1 interlayer is carbon fiber exothermic part 2, electric appliance control box 3 is provided with control switch 4, charging jack 5, supply socket 6, heater 2 leads insert in the supply socket 6 of electric appliance control box during use, control switch 4 is allocated to temperature required, the thermostatic control system in the electric appliance control box reaches by the operating voltage of adjusting heater adjusts electric blanket temperature to set point.
Be provided with automatic constant temperature system, battery automatic monitored control system in the electric appliance control box.
Thermostatic control system reaches the purpose of constant temperature by heat-sensitive sensor and power switch circuit TWH8778 or TWH8751 control heater size of current and the length of conduction time.
The battery automatic monitored control system is provided with in order to prevent excessive the discharging and recharging of rechargeable battery; it is to utilize the stabilized voltage characteristic of voltage-stabiliser tube to check cell voltage; the break-make of control whole system power supply circuits when cell voltage is higher or lower than protection voltage, can be cut off the electricity supply automatically.
