Abstract
The utility model discloses a schoolbag, which belongs to the technical field of study articles, and comprises a bag body, straps, two sandwich layers and rainproof cloth. The sandwich layer 1 is provided with a zipper connected with the rainproof cloth. When not in use, the rainproof cloth is put in the sandwich layer 1; when an umbrella is opened on a rainy day, the rainproof cloth is put down to block rain for the schoolbag; and the rainproof cloth can have different patterns for a user to select. The sandwich layer 2 is a sealing sandwich layer, wherein phase-change materials are sealed in the sandwich layer 2; when the temperature is higher than the phase-change temperature, the phase-change materials absorb heat; and when the temperature is lower than the phase-change temperature, the phase-change materials release heat, and thereby the back part of the schoolbag can maintain a certain temperature.
Description
Technical field
The utility model relates to school bag, and more particularly, the utility model relates to the constant temperature school bag.
Technical background
Existing school bag has increased newly than before as variable volume, and is antitheft, many functions such as Reduction of Students' Study Load.But keeping remaining blank on the constant temperature, rainproof upward effect is bad.
Summary of the invention
Summer the back knapsack back of going to school contact always awfully hotly with school bag, feel very uncomfortable, arrived school and also can get the back wet.Rainy day the back school bag hold up an umbrella, the water that flows down on the umbrella always can be got school bag wet.The invention provides a kind of constant temperature but also can be of not only can having kept in order to overcome above problem at rainproof school bag of rainy day.
This school bag is achieved by the following technical programs:
In order to realize purpose of the present invention, the one side that this school bag is connected with inclusion at braces is provided with a Sealed sandwich, is provided with interlayer above the inclusion.
What described braces was connected sealing in the interlayer of one side with inclusion is the phase-transition heat-preserving material, absorb heat when temperature is higher than phase transition temperature, thereby heat release reaches the purpose that keeps constant temperature when temperature is lower than phase transition temperature.What place in the interlayer above the described inclusion is the rainproof cloth that links to each other by slide fastener with inclusion, and it is that school bag keeps off the rain when holding up an umbrella that this rainproof cloth is used for the rainy day, different patterns can be arranged on this cloth and can dismantle, and the user can be according to hobby change cloth.
This school bag has the following advantages:
1, simple in structure being convenient to produced.
2, can keep the constant temperature can be rainproof practical.
3, it is elegant in appearance to change the pattern of rainproof cloth.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: school bag waterproof cloth feed collet layer 1 phase-transition heat-preserving material interlayer 2
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Interlayer 1 is an interlayer of placing rainproof cloth, in slide fastener is arranged, rainproof cloth is connected by slide fastener with inclusion, rainproof cloth can have different pattern users to select according to hobby.Interlayer 2 is wherein sealing the phase-transition heat-preserving material for Sealed sandwich, and the phase transition temperature of this material is about 30 degrees centigrade.When temperature is higher than phase transition temperature the heat absorption heat release when being lower than phase transition temperature, the temperature maintenance of human body back and school bag in suitable temperature.
Claims (3)
1. a school bag comprises inclusion, and braces and interlayer is characterized in that, the one side that inclusion is connected with braces has interlayer, and interlayer is arranged above the inclusion.
2. according to claims 1 described school bag, it is characterized in that the interlayer of the one side that described inclusion is connected with braces is a Sealed sandwich, is the phase-transition heat-preserving material in the interlayer.
