Cold and heat double-supply type solar backpack

Abstract

The invention provides a cold and heat double-supply type solar backpack, which is capable of heating sweat of a user so as to promote volatilization and to regulate temperature of an ambient environment of the user. The solar backpack is characterized by comprising a backpack main body, a supporting piece, a temperature regulating part, a power supply part and a control part, wherein a cavity is kept in the supporting piece; the temperature regulating part comprises a breathable cotton layer which is paved on one side of the supporting piece, an anti-condensing, heat-insulating and gas-proofing laminated board which is arranged in the supporting piece and semiconductor refrigerating sheets which are arranged on the anti-condensing, heat-insulating and gas-proofing laminated board; the power supply part comprises a lithium battery, a solar cell panel and a charging protector; the control part comprises a controller, wherein an air inlet is formed in the lower side of the supporting piece and air outlets are formed in the upper side of the supporting piece; the temperature regulating part further comprises a fan which is arranged in the air inlet; by virtue of the fan, moist and heat air and cold air are discharged to the air outlets and are mixed, so that mixed air at a certain temperature is formed; and the mixed air is discharged from the air outlets and participates in heat exchange with ambient air of the user, so that temperature regulating is implemented, and a purpose of preventing rheumatic diseases in the user is achieved.

Description

technical field [0001] The invention relates to a solar energy backpack, in particular to a cooling and heating dual-supply solar energy backpack. Background technique [0002] Nowadays, there are more and more backpackers whether they are working, going to school or traveling, but today’s backpacks do not have a good back cooling device, and the resulting problem is that the parts of the backpack that are in contact with the human body can easily cause the human body to sweat and get wet , produce discomfort, if things go on like this can cause skin diseases such as rheumatism and eczema. [0003] Existing semiconductor refrigeration packs generally use refrigeration sheets to directly contact the back of the human body, which can easily cause local temperature discomfort, which will seriously block blood circulation, close the sweat pores on the back, and cause diseases such as folliculitis. At the same time, there is no external support device for the cooling sheet, whic...

Problems solved by technology

[0002] Nowadays, there are more and more backpackers whether they are working, going to school or traveling, but the current backpacks do not have a good back cooling device, and the resulting problem is that the parts of the backpack that are in contact with the human body can easily cause the human body to sweat and get wet , produce discomfort, and in the long run, it will cause skin diseases such as rheumatism and eczema

[0003] Existing semiconductor refrigeration packs generally use refrigeration sheets to directly contact the back of the human body, which can easily cause local temperature discomfort, which will seriously block blood circulation, close sweat pores on the back, and cause folliculitis and other diseases

At the same time, there is no external support device for the cooling plate, which is easy to be crushed and damaged
