Abstract
The utility model discloses a cool and warm dual-purpose knapsack, comprising a bag body front face and a bag body rear face, wherein the bag body rear face is provided with a hollow hard interlayer; the interlayer is internally provided with a plurality of fans; one side of the interlayer, which is in contact with a back part, is fixedly provided with a plurality of self-temperature-controlling electric heating belts; a gap between the every two self-temperature-controlling electric heating belts on the interlayer is provided with a plurality of through holes; the bag body front face is provided with a solar cell panel and a selective switch; and the fans and the self-temperature-controlling electric heating belts form a closed loop circuit through the selective switch and the solar cell panel. The cool and warm dual-purpose knapsack disclosed by the utility model integrates heat insulation and warm keeping functions, and can be used all the year round; in summer, solar energy can supply power to the fans and cold air is transmitted to the back part through the through holes so as to improve the heat radiation and ventilation conditions between the back part and the bag body; and in winter, the solar energy supplies the power to the self-temperature-controlling electric heating belts to generate a suitable temperature to keep the back part warm. The cool and warm dual-purpose knapsack disclosed by the utility model does not need a battery or has to be pre-charged, so that the energy source is saved and influences caused by the environment are smaller; and the cool and warm dual-purpose knapsack is simple in structure, and is convenient and practical.
Description
Technical field
The utility model relates to a kind of bag, relates in particular to a kind of both cooling and heating knapsack.
Background technology
in daily life, knapsack is even with its active force, reasonable stress, enjoy consumers welcomed, but knapsack has a problem, be exactly that human body back is close at the knapsack back side all the time, when temperature raises, inclusion and human body close contact place can't breathe freely, can't distribute after perspiring, will produce the sensation of sultry discomfort, and, perspire and can not in time kill again in the back, easily cause various skin diseases, if cold weather, the knapsack back side does not have again good attemperator, do not have good heat insulation effect, people have also done a lot of improvement for knapsack, as increase air-permeable mattress, but can not play good effect, can not be heat insulation, the effect of insulation focuses on a knapsack simultaneously, and present heat insulation, attemperator, all need battery or pre-charge, trouble wastes energy again.
Summary of the invention
The purpose of this utility model just is to provide a kind of and addresses the above problem, and integrates heat insulation, is incubated, energy savings, wide application, less both cooling and heating knapsack affected by environment.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of both cooling and heating knapsack, comprise the positive and inclusion of the inclusion back side, the inclusion back side is provided with a hollow hard sandwich, be provided with several fans in interlayer, be fixed with several self temperature control heating tapes on interlayer and one side that the back contacts, on interlayer, the gap of temperature self controlled electrically-heated interband has several through holes, the inclusion front is provided with solar panel and selector switch, and described fan and self temperature control heating tape all consist of the closed-loop path by selector switch and solar panel.
As preferably: described fan is two.
As preferably: described several self temperature control heating tapes are connected in parallel.
Compared with prior art, the utility model has the advantage of: integrate heat insulation, warming, the four seasons all can use, be fan power supply by solar energy summer, cool breeze sees through through hole and is sent to the back, improves the heat dissipation ventilation situation between back and inclusion, and be self temperature control heating tape power supply by solar energy winter, producing suitable temperature is that the back is warming, the utility model need not to use battery or precharge, and energy savings is affected by environment less, simple in structure, convenient and practical.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment 1.
Fig. 2 is the functional circuit of this utility model.
In figure: 1, inclusion is positive, and 2, the inclusion back side, 3, interlayer, 4, fan, 5, self temperature control heating tape, 6, through hole, 7, solar panel, 8, selector switch.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1: referring to Fig. 1, Fig. 2, the utility model comprises inclusion positive 1 and the inclusion back side 2, the inclusion back side 2 is provided with a hollow hard sandwich 3, be provided with two fans 4 in interlayer 3, be fixed with the self temperature control heating tape 5 of three parallel connections on interlayer 3 and one side that the back contacts, on interlayer 3, the gap of 5 of self temperature control heating tapes has four through holes 6, inclusion front 1 is provided with solar panel 7 and selector switch 8, and described fan 4 and self temperature control heating tape 5 all consist of the closed-loop path by selector switch 8 and solar panel 7.
summer is when using, can select fan 4 to be connected with solar panel 7 by selector switch 8, by solar powered drive fan 4 work, the cool breeze that fan 4 produces is delivered to the back by through hole 6, improve the circulation of air situation of the inclusion back side 2 and back contact-making surface, make human body sensory comfortable nice and cool, hollow hard sandwich 3 can be played a supporting role, can not push fan 4, during use in winter, can select solar panel 7 by selector switch 8 is self temperature control heating tape 5 power supplies, self temperature control heating tape 5 can be controlled at temperature in suitable scope, temperature can be not too high or too low, can provide good thermal source for human body back, play the effect of insulation, adopt mode in parallel between self temperature control heating tape 5, if wherein one breaks down, can not affect whole heat supply, the collecting and distributing heat of the utility model, warming in one, be fit to four seasons use, adopt solar panel 7 power supplies, need not to use battery or precharge, simple in structure, widely applicable.
