Description

Technical Field

[0001] The invention relates to a pot cover assembly and a food processor using the pot cover assembly. Background Art

[0002] With the development of society, people's pursuit of quality of life is constantly improving. More people choose to cook their own food, and food processors are also popular in the market. Food processors combine multiple functions such as cooking, juicing, grinding, and stirring. They can not only cook dishes, but also squeeze juice and stir meat stuffing. The cup body and the machine base are detachable for easy storage. It has the characteristics of one machine with multiple uses and easy to use. The lid of the existing food processor needs to be opened and closed by the user. If a food processor is used to cook dishes, when the juice needs to be collected, the lid cannot be opened automatically to allow the water vapor to escape, resulting in too much soup in the dish, affecting the quality and taste of the dish. When it is necessary to add ingredients, the user must open the lid by himself, which causes artificial inconvenience.

[0003] To this end, the Chinese patent application with application number 201910567755.2 discloses a food processor that can automatically open and close the lid of the pot, which includes a machine base, a pot body with an opening on the top of the machine base, a pot lid arranged at the opening of the pot body, and the pot lid is connected to a flip cover arm, one end of the flip cover arm is rotatably connected to the machine base, and a driving mechanism is provided in the machine base that can drive the flip cover arm to rotate so as to drive the pot lid to open from the opening of the pot body or drive the pot lid to be set at the opening of the pot body. The driving mechanism can drive the flip cover arm to rotate at different angles, so that the pot lid opens at different angles, realizing the functions of collecting juice and adding dishes. However, in this structure, during the process of opening the pot lid, the entire pot lid is in an open state as a whole. If the stirring component or knife group in the food processor is still rotating at a high speed, there is a risk that the high-temperature soup will easily spill out of the pot body. Therefore, many food processors are designed with a pressing structure to press the cup cover onto the cup body during the structural design process. When the food processor is in use, the cup cover needs to be pressed against the cup body first to prevent the cup body from shaking and reduce the noise of the whole machine. At the same time, as long as the food processor is executing a certain cooking program, the pot cover is not allowed to separate from the pot body during the process. Therefore, how to achieve filling and juice collection for food processors with such pot covers still needs further improvement. Summary of the invention
