[0025] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Please see attached Figure 1 To Attachment Fig. 9 A pressure cooker comprises a pot body 2 and a pot cover assembly matched with the pot body, the pot cover assembly comprises a pot cover 1, the pot cover 1 is provided with a lower handle 3, the lower handle 3 is provided with an upper handle assembly 4 which can rotate relative to the lower handle, the upper handle assembly 4 is provided with a movably arranged pressure limiting valve 5, the pot cover 1 is provided with an exhaust pipe 6 fixed to the pot cover and extending into the pressure limiting valve 5, the pressure limiting valve can move up and down relative to the exhaust pipe, specifically, the upper handle assembly 4 comprises a standable handle 41 and a handle decorative cover 42, the standable handle 41 is provided with a boss 411, the lower handle 3 is provided with a cavity 31 for the boss 411 to extend into relative to the standable handle 41, the handle decorative cover 42 is provided with a handle hook 421, the standable handle 41 is provided with a handle slot 410 which cooperates with the handle hook 421 to fix the handle decorative cover 42 to the standable handle 41. During assembly, the decorative cover can be fixed on the standable handle by aligning the handle hook and snapping it into the handle slot, and then the boss on the standable handle cooperates with the cavity on the lower handle to achieve preliminary positioning of the upper handle assembly, which has a reasonable structure.

[0027] Furthermore, a rotation positioning structure is provided between the upper handle assembly 4 and the lower handle 3, and the upper handle assembly 4 is switched between the first state and the second state through the rotation positioning structure, and in the second state, the upper handle assembly lifts the pressure limiting valve 5 to achieve exhaust. Specifically, the circumference of the boss 411 is provided with a mounting groove 412, and the rotation positioning structure includes a positioning block 72, a positioning pin 71 and an elastic member 73. The positioning block 72 is arranged in the mounting groove 412, and a positioning cavity 721 and a fixing stud 722 are provided on the positioning block 72. The positioning pin 71 is arranged in the positioning cavity 721 and partially protrudes from the circumference of the boss 411. The elastic member 73 is a compression spring, which abuts between the positioning pin 71 and the standable handle 41 to provide elastic force to the positioning pin so that it protrudes from the circumference of the boss, and is movably arranged in the positioning cavity. The fixing stud 722 fixes the positioning block 72 to the standable handle 41 by screws. During assembly, the locating pin is installed into the locating cavity of the locating block, and then the compression spring is installed to form a locating assembly, and then the locating assembly is installed into the mounting groove of the standable handle, and the locating assembly is fixed in the standable handle by screws through fixing studs to form an independent upper handle assembly, which is easy to disassemble and clean.

[0028] In this embodiment, the side wall of the cavity 31 is provided with a slide groove 32 for the positioning pin 71 to be inserted into. The slide groove 32 is arranged along the circumference of the cavity 31 and is provided with a first slot 33 for the positioning pin 71 to be inserted into and a second slot 34 for the positioning pin to be inserted into. The second slot 34 is located at the end of the slide groove 32, and the first slot 33 is arranged between the slide groove insertion port and the second slot 34. The specific process of fixing the upper handle assembly on the lower handle is as follows: align and insert the positioning pin into the insertion port of the lower handle slide groove, and then rotate clockwise, the positioning pin is pushed into the positioning cavity, the compression spring is compressed, and the positioning pin slides in the slide groove. When the standable handle is rotated until the positioning pin is just inserted into the first slot (that is, when the standable handle is rotated to be parallel to the lower handle, the first state switching is completed), the pressure cooker is switched to the working gear, and the compression spring pushes the positioning pin out, so that the standable handle is fixed in the working position. When the standable handle is rotated until the positioning pin just fits into the second slot (that is, when the edge of the pot cover, the lower handle and the standable handle form a triangle supported on the table, the second state switching is completed), the compression spring pushes the positioning pin out, so that the standable handle is fixed in the standable position.

[0029] In this embodiment, an assembly cavity is provided on the side of the standable handle 41 opposite to the boss 411, and the pressure-limiting valve 5 is arranged in the assembly cavity after passing through the handle decorative cover 42, and the slide groove 32 gradually rises along the side wall of the cavity 31, and the vertical height of the center of the second groove 34 from the bottom surface of the cavity 31 is higher than the vertical height of the center of the first groove 33 from the bottom surface of the cavity 31, the vertical height H between the second groove 34 and the first groove 33 is greater than the distance D between the bottom surface of the pressure-limiting valve 5 and the inner bottom surface of the standable handle, and the radial depth of the first groove 33 and the second groove 34 along the side wall of the cavity 31 is greater than the depth of the slide groove 32. After cooking is finished, open the pot lid and rotate the stand-up handle clockwise. In the process of rotating the stand-up handle clockwise from the working position to the stand-up position, due to the spiral rise of the slide groove, the rising height from the center of the first slot to the center of the second slot is H, where H>D. In the process of clockwise rotation, the bottom surface of the stand-up handle will contact the bottom surface of the pressure limiting valve, thereby lifting the pressure limiting valve to achieve the purpose of rapid pressure relief.

[0030] In addition, the stand-up handle can be removed by turning it counterclockwise to the position where the slide slot is inserted, which is convenient and quick to clean.

[0031] Preferably, three mounting grooves 412 are provided, and the three mounting grooves are evenly distributed along the circumference of the boss, each mounting groove is provided with the positioning pin 71, and three sliding grooves 32 are also provided correspondingly, and the three sliding grooves are evenly distributed along the circumference of the cavity, so that the stand-up handle can be more stably installed on the lower handle, and the structure is simple.

[0032] In order to facilitate the assembly of the standable handle, in this embodiment, the standable handle 41 is provided with an indication protrusion 413 in the circumference, and the upper surface of the lower handle 3 is provided with an indication icon 35 that cooperates with the indication protrusion 413 to facilitate the boss 411 of the standable handle to extend into the cavity 31 of the lower handle and insert the positioning pin 71 into the slide groove 32. Align the indication protrusion on the upper handle assembly with the indication icon on the lower handle to complete the alignment of the positioning pin and the slide groove, and then insert the positioning pin into the slide groove and rotate it clockwise to complete the assembly of the standable handle.

[0033] The pressure cooker of the present application can fix the upper handle in the standing position by rotating the standing handle clockwise, and then open the pot cover, and form a triangular support through the edge of the pot cover, the lower handle and the standing handle, so that the pot can stand on the table, thereby reducing the space occupied by the pot cover. At the same time, the pressure limiting valve can be indirectly pushed out during the process of rotating the standing handle, thereby achieving the purpose of safe, fast and rapid pressure relief.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
