Multipurpose knapsack with heat dissipation and cooling function

Abstract

The invention relates to a multipurpose knapsack with a heat dissipation and cooling function. The multipurpose knapsack comprises a knapsack body (1), and is characterized in that a base plate seat (2) is fixed on the bottom of the knapsack body (1), one or more extractor fans (3) are installed in the internal cavity of the base plate seat (2), a solar cell panel (7) is installed on the external surface of the knapsack body (1), the solar cell panel (7) is connected with an electric energy conversion module (8), the output terminal of the electric energy conversion module (8) is connected with a storage battery (9), the output terminal of the storage battery (9) is connected with a charging interface (10), and the charging interface (10) is arranged in the outer side of the base plate seat (2). The extractor fans on the bottom of the knapsack body can accelerate air flow on the back, and can provide cool air flow for the user, the multipurpose knapsack has a heat dissipation and cooling function and is good in comfortableness, the solar cell panel can provide power for miniature current-using equipment such as mobile phones, and the multipurpose knapsack is beneficial to usage of electronic products during the outdoor exercise process.

Description

technical field [0001] The invention relates to a multi-purpose backpack, in particular to a multi-purpose backpack capable of dissipating heat and cooling, and belongs to the technical field of daily necessities. Background technique [0002] It is generally necessary to carry a backpack for outdoor sports or traveling. The backpack is close to the back, not ventilated, and the temperature is high. When the external temperature is high, it is easier to sweat, and the use comfort is poor. Moreover, the existing knapsack has a simple structure and cannot provide power for small electrical equipment such as mobile phones, which is unfavorable for the use of electronic products during outdoor sports. Contents of the invention [0003] The purpose of the present invention is to solve the defects and insufficiencies of existing knapsacks which are simple in structure, do not have the function of heat dissipation and cooling, are poor in use comfort, and cannot provide power for...
