Description

Technical Field

[0001] The utility model discloses a multifunctional student chair with heating function, belonging to teaching equipment. Background Art

[0002] In winter, students' hands and feet are not flexible when studying and doing homework due to the cold weather, which affects their studies. Long-term exposure to cold weather can cause great harm to the body. At the same time, there are more and more student supplies and tools, and schoolbags can't be put into the desk. Putting a small schoolbag on the chair can solve this problem. There also needs to be a place to put items such as water cups. This requires a device that can meet the needs of sitting and studying, keep the body warm, and place schoolbags, water cups and other items. A multifunctional student chair is needed to solve the problem. There are no similar products on the market. Some electric heaters with heating function cannot meet the above needs, and they have high power and waste energy. Therefore, people are in urgent need of good products that can solve these problems. Utility Model Content
