Cover opening and closing damping limit device and cooking appliance

Abstract

The invention discloses a cover opening and closing damping limit device and a cooking appliance. The cover opening and closing damping limit device realizes self-locking through a damping device so as to allow the cooking appliance to be fixed at any angle within the defined maximum opening and closing cover angle range without any limitation by the weight of the cover. Consequently, the cover opening and closing damping limit device and the cooking appliance are easy to use.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a lid opening and closing damping and limiting device and cooking utensils. Background technique [0002] There are many types of electric cookers on the market. According to the opening and closing of the lid, there are mainly split type and one-piece type. Among them, the split type pot lid is separated from the base. When taking out food, the pot lid needs to be taken out. It is not very convenient for users to use it, but the one-piece pot cover is movably connected with the base body, and the pot cover and the base body do not need to be separated, which is more convenient for users to use. Therefore, the pot with this one-piece pot cover It is becoming more and more popular. Specifically, the one-piece pot cover is generally hinged on the base through a rotating shaft. The rotating shaft is covered with a torsion spring. The two ends of the torsion spring are respe...

Problems solved by technology

[0004] 1. Like an ordinary electric rice cooker, the lid is relatively light. When the lid is opened, the hinged part of the lid rotates relative to the hinged part. The self-locking of the lid is made by springs and hooks between simple parts. It is easy to open and close the lid, but it is only suitable for the situation that the lid is light, and this structure cannot be used when the lid is heavy

[0005] 2. When the lid is heavy, it is like the lid of an egg beater, meat grinder, dough kneader, or fryer. There are motors, wind wheels, blades and other accessories on the lid, so the lid will be very heavy. Ordinary The self-locking structure of opening the cover cannot support the limit function at a certain angle, so these machines have a head locking mechanism to lock the machine head; specifically, it is mainly fixed by inserting a positioning pin into the middle of the two parts After opening the cover, press the switch to make the positioning pin pass through the two parts to fix it. This fixing method is limited to a few specific angles, which cannot meet the needs of different customers at any angle, and usually requires additional Auxiliary switch off to achieve, the operation is inconvenient
