Description

Technical Field

[0001] The invention relates to an automatic cover flipping device and a food processor using the automatic cover flipping device. 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 widely popular in the market. While food processors provide people with a convenient cooking method, they also have some problems.

[0003] Currently, most food processors on the market require users to open and close the lids themselves. During the cooking process, if you need to collect juice, the lid cannot be opened automatically, causing the steam to escape, resulting in too much soup in the dish, affecting the quality and taste of the dish. When you need to add ingredients, you must open the lid yourself, which is inconvenient. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide an automatic lid-turning device capable of opening a pot lid to two different angles in view of the above-mentioned prior art.

[0005] The second technical problem to be solved by the present invention is to provide a food processor using the automatic cover opening device according to the above-mentioned prior art.

[0010] And the setting positions of the first micro switch and the second micro switch satisfy:

The first surface or the first arc surface continues to touch the first micro switch, while the other side of the cam never touches the second micro switch; when the cam continues to rotate in the first direction driven by the output shaft of the driving motor, and the rotation angle is equal to β, the first inclined surface or the first arc surface on one side of the cam always touches the first micro switch, and the second inclined surface on the other side of the cam begins to touch the second micro switch; when the cam continues to rotate in the first direction driven by the output shaft of the driving motor, and the rotation angle is greater than β, the first inclined surface or the first arc surface on one side of the cam always touches the first micro switch, and the second inclined surface or the second arc surface on the other side of the cam always touches the second micro switch, β>α.

[0014] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a food processor using the above-mentioned automatic lid-opening device, comprising a cup body with an opening on the top, and a pot cover arranged at the opening of the cup body, characterized in that: the pot cover is connected to the automatic lid-opening device with the above-mentioned structure.

[0015] As an improvement, the food processor provided by the present invention further includes a machine body, the cup body is arranged on the machine body, and the automatic cover-opening device is fixed on the machine body.
