[0023] At present, the lid and the pot body of the pressure cooker are locked by rotating the lid with a long handle, and the lid is opened and closed by rotating. When operating, the user needs to use both hands to operate and drive it to rotate, which is inconvenient to use, and the extended long handle affects the overall aesthetics of the pressure cooker.
[0024] For this purpose, refer to Figure 1 , Figure 2 and Figure 3, is a pressure cooker proposed by the utility model, comprising a pot body 100, a cover body 200 and a locking assembly 300. The pot body 100 is provided with a heating chamber with an opening 110 at the upper part, and a fixed side plate is arranged around the outer edge of the opening 110 of the pot body 100. The cover body 200 is covered on the upper part of the pot body 100 to block the opening 110. The locking assembly 300 is used to lock or open the pot body 100 and the cover body 200. The locking assembly 300 comprises a mounting seat 350 and two limiting frames 310 relatively arranged at both ends of the mounting seat 350. The mounting seat 350 is fixedly connected to the cover body 200 and is provided with a driving gear 330. The limiting frame 310 is an arc-shaped groove structure, and the opening 110 faces one side of the pot body 100. The upper and lower side edges of the limiting frame 310 can respectively abut against the upper surface of the cover body 200 and the fixed side plate. On the lower surface of the plate, the limit frame 310 is connected to the driving plate 320, and the driving plate 320 is provided with a driving rack 340. The driving rack 340 is meshed with the driving gear 330, and the driving gear 330 is connected to the driving part 400. The driving part 400 extends above the cover body 200. The driving part 400 rotates to drive the driving gear 330 to rotate, and then drives the limit frame 310 to translate toward or away from the cover body 200 to lock or open the pot body 100 and the cover body 200. It can be understood that the cover body 200 generally has a hood-like structure with a slight arch. The cover body 200 is placed on the pot body 100 corresponding to the position of the opening 110, and then the driving part 400 is rotated to drive the driving gear 330 to rotate. Further, the driving rack 340 meshing with the driving gear 330 translates toward one side of the driving gear 330 as the driving gear 330 rotates. The driving plate 320 connected to the driving rack 340 then drives the limit frame 310 to translate toward the inner side of the cover body 200 until the limit frame 310 is embedded in the connection between the cover body 200 and the pot body 100, and the upper and lower side edges of the limit frame 310 respectively abut the upper surface of the cover body 200 and the lower surface of the fixed side plate, thereby achieving the locking of the cover body 200 and the pot body 100. When the cover body 200 needs to be opened, the driving plate 320 drives the driving gear 330 to rotate, thereby driving the driving rack 340 to translate toward the outside away from the driving gear 330, and then drives the limit frame 310 to move toward the outside of the cover body 200. The two side plates of the limit frame 310 are separated from the cover body 200 and the fixed side plates, thereby achieving unlocking.
[0025] It should be noted that the teeth of the limiting rack are located on the side close to the driving gear 330 and the two are opposite to each other, which is an internal tooth setting. In other embodiments, the teeth of the two limiting racks are located on the opposite sides, which is an external tooth setting. In the two embodiments, the rotation direction for achieving locking is different, which is not the only limitation here.
[0026] Reference Figure 2The driving plate 320 is provided with a guide hole 322, and a guide shaft is passed through the guide hole 322. The guide shaft is connected to the top surface of the cover body 200 to guide the moving direction of the driving plate 320 to prevent the driving plate 320 from shifting in the translation direction, causing the limit block to be unable to move and then stuck, thereby ensuring the normal use of the locking assembly 300.
[0027] Reference Figure 2 The cover body 200 is provided with an air valve 500, and the driving plate 320 is provided with a limiting hole 321 corresponding to the position of the air valve 500. The limiting hole 321 includes two connected wide holes 321a and a narrow hole 321b. The narrow hole 321b is located on the side away from the limiting frame 310. When the pressure cooker is started, the air valve 500 moves upward and can abut against the hole wall of the narrow hole 321b to limit the movement of the limiting frame 310 toward the outside of the cover body 200, so as to completely lock the pot body 100 and the cover body 200. It should be noted that after the pressure cooker is heated, high pressure is generated inside, which in turn drives the gas valve 500 to move toward the outside of the cover body 200, that is, to move upward, so that it extends out of the limiting hole 321. At this time, when the driving part 400 drives the driving plate 320 to move, the limiting hole 321 abuts against the side wall of the gas valve 500, limiting the movement of the driving part 400, thereby achieving complete locking of the cover body 200 and the pot body 100, thereby eliminating the safety risks caused by the pressure cooker being opened during use.
[0028] In other embodiments, it should be noted that the valve body of the air valve 500 is in a cone shape with a narrow top and a wide bottom. If the initial position of the air valve 500 extends out of the limiting hole 321, the limiting effect is achieved by setting the narrow hole 321b and the wide hole 321a. The narrow part of the air valve 500 is initially located in the wide hole 321a, and the narrow part can smoothly enter the narrow hole 321b. The remaining distance is enough for the driving plate 320 to move and drive the limiting frame 310 to disengage. When in use, the air valve 500 is lifted up due to high pressure, and its wide part enters the wide hole 321a but cannot enter the narrow hole 321b. At this time, the rotating driving part 400 will cause the hole wall of the wide hole 321a to abut against the side wall of the air valve 500, so that the cover body 200 and the pot body 100 are completely locked.
[0029] Reference Figure 2 The mounting seat 350 is provided with limiting side plates 351 on both sides along the length direction. The limiting side plates 351 can abut against the side walls of the driving plate 320 and the driving rack 340 to limit the driving plate 320 or the driving rack 340 from slipping, further ensuring the normal use of the locking assembly 300.
[0030] Reference Figure 1 and Figure 3The driving part 400 includes a sleeve 420 and a turntable 410 connected to the top of the sleeve 420. The bottom of the sleeve 420 is provided with a special-shaped groove 421. The top of the driving gear 330 is provided with a special-shaped boss 331. The sleeve 420 is engaged with the special-shaped boss 331 through the special-shaped groove 421 to fix the driving gear 330. The user opens and closes the cover 200 through the turntable 410, which is convenient to use and replaces the long handle structure, making the overall appearance of the pressure cooker more beautiful. Optionally, the peripheral side wall of the turntable 410 is provided with anti-slip convex patterns 411, so as to increase the friction of the contact surface and facilitate the user to rotate the turntable 410.
[0031] Reference Figure 1 The locking assembly 300 also includes a cover body, which is disposed above the mounting seat 350 to cover the driving plate 320 to maintain the consistency of the appearance of the pressure cooker.
[0032] Reference Figure 1 Two lifting handles 130 are arranged at opposite positions along the side wall of the pot body 100 to facilitate users to take the pressure cooker and prevent burns caused by direct contact with the pot body 100.
[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
