Description

Technical Field

[0001] The utility model relates to the technical field of lunch box crushing, and particularly relates to a lunch box crusher. Background Art

[0002] As the name implies, a lunch box is a container used to hold food and is convenient for carrying and eating. With the accelerating pace of life and the rise of the takeaway culture, lunch boxes are used more and more widely in daily life. They not only appear in occasions such as family dinners, picnics, and outdoor activities, but also become an important tool for groups such as office workers and students to solve lunch problems. There are various types of lunch boxes, which can be divided into plastic lunch boxes, paper lunch boxes, metal lunch boxes, etc. according to factors such as material, function, and size. Among them, although plastic lunch boxes are light, waterproof, and easy to clean, the plastic material is difficult to degrade and requires a lunch box crusher to crush it for subsequent recycling and reducing environmental pollution.

[0003] The existing lunch box crusher uses crushing components to extrude and break waste lunch boxes. During operation, vulnerable parts such as blades and crushing plates rub against the lunch boxes and will gradually wear out and need to be replaced regularly. In order to ensure the crushing effect, the crushing components are tightly arranged with the outer shell. The internal space of the outer shell is narrow, which is not convenient for disassembling and maintaining the vulnerable parts, resulting in a large amount of manpower and time being required to maintain the device. Therefore, we propose a lunch box crusher to solve the problems mentioned above. Summary of the Utility Model
