Description

Technical Field

[0001] This utility model relates to the field of cookware technology, specifically to a cookware with a knob-type limit. Background Technology

[0002] Cookware is a utensil used for cooking, typically made of metal, ceramic, or other heat-resistant materials. Its main function is to hold food and use heat to perform various cooking methods such as boiling, stewing, stir-frying, and pan-frying. Cookware designs vary widely; the bottom is usually flat to ensure even heat distribution, while the edges are designed to be high, low, or curved depending on the intended use. Handles facilitate gripping and movement, and some cookware is also equipped with lids to lock in heat and moisture. Whether in a home kitchen or a professional restaurant, cookware is an indispensable tool; it is not only the core medium for cooking but also influences the taste and efficiency of the dishes.

[0003] Most existing cookware has a fixed design, which makes locking and unlocking the lid cumbersome. Accidental opening during locking poses a safety hazard. Furthermore, most cookware cannot separate soup from food, requiring manual removal of the food, which is complicated, time-consuming, and results in a poor user experience. Some cookware has a detachable device, but it is difficult to disassemble and clean thoroughly, leaving residue. Summary of the Invention

During the process of separating the soup and ingredients using the bidirectional single-sided strainer 4, first, engage the locking shaft 421 on the strainer assembly 402 with the mounting locking assemblies 401 on the left and right sides of the inner side of the pot body 1. During engagement, press the locking shaft 421 firmly into the locking groove 412 to complete the engagement. To remove it, simply pull it upwards. During the process, the locking shaft 421 moves along the arc-shaped limiting block 4133. The arc-shaped limiting device 413 is under pressure, causing the telescopic spring 4132 to contract. This completes the locking and unlocking process. After the filter plate assembly 402 and the mounting locking assembly 401 are locked together, the first snap button 4231 is connected to the locking body 403. During the connection process, the locking tongue 4234 contracts along the locking fixing groove 431 to complete the locking. When it is necessary to remove the device, press the second snap button. The connecting post 4237 causes the connecting post 4237 on the first snap 4231 to move downward. When the connecting post 4237 moves downward, it causes the annular elastic band 4236 to contract. Subsequently, the annular elastic band 4236 causes the snap tongue 4234 to contract, and then it can be removed from the snap fixing groove 431. During the removal process, the snap tongue 4234 on the second snap 4232 can act as a handle to facilitate the removal of the snap assembly 423 from the snap body 403.
