Description

Technical Field

[0001] This utility model relates to the field of pressure cooker lid opening and closing technology, and in particular to a pressure cooker lid opening and closing device. Background Technology

[0002] A pressure cooker, also known as a pressure pot or pressure casserole, is a type of kitchen cookware. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure. By applying pressure to water, the water reaches a higher temperature without boiling, thus speeding up the cooking process. It can heat food to over 100°C. In high-altitude areas, pressure cookers can prevent the problem of water's boiling point lowering and food becoming difficult to cook thoroughly.

[0003] The upright clamping pot lid and pressure cooker disclosed in Chinese patent CN215874270U include a lid body, a clamping mechanism and a support handle. The support handle is rotatably connected to the clamping mechanism to control the opening and closing of the clamping mechanism. A first support point is provided on the outer edge of the lid body or the outer edge of the clamping mechanism. Two second support points are provided on the outer end of the support handle. The first support point and the two second support points act simultaneously on the placement surface to keep the pot lid in an upright state.

[0004] When the existing pressure cooker needs to be opened, the safety valve must be pressed down to disengage the bottom of the safety valve from the valve hole. The support handle is then rotated to move the top of the safety valve into the movable hole, and then the clamping mechanism is opened. However, the pressure inside the pressure cooker is high during use. If the lid is opened directly, steam will rush out and easily burn the user, resulting in low safety.

[0005] To solve the above problems, this utility model proposes a pressure cooker lid opening and closing device. Utility Model Content

The driving component and the fastening components slide together.

[0008] Preferably, the driving component includes a limiting frame and a driving disc. A driving groove is fixedly installed on the upper surface of the pot lid, and the driving disc is rotatably installed inside the driving groove. The upper surface of the driving disc is integrally formed with a limiting frame, and a handle is installed on the outer side of the limiting frame for limiting.

[0009] Preferably, the buckle member comprises movable plates and lid teeth of a pot cover, the upper end surface of the pot cover is uniformly provided with the movable plates in a sliding manner, and the movable plates are slidably connected with the driving disc.

[0010] Preferably, the outer side of the pot cover is provided with a cover, and the handle extends upwards to above the cover.

[0011] Preferably, two guide grooves are formed in each movable plate, a guide rod is fixedly installed on the upper end surface of the pot cover and corresponds to the position of the guide groove, and the guide rod is slidably installed in the guide groove.

[0012] Preferably, a through groove is formed in each movable plate, a second spring is fixedly connected in the through groove, a division frame is fixedly installed on the upper end surface of the pot cover, and the other end of the second spring is fixedly connected with the division frame.

[0013] Preferably, a driving guide groove is formed in the driving disc and corresponds to the position of each movable plate, the driving guide groove is in an L shape, a sliding block is slidably installed in the driving guide groove, and the sliding block is fixedly connected with the corresponding movable plate.

[0040] The movable plate 9 is provided with a float hole 23, the pot cover 10 is slidably provided with a float 16 at a position corresponding to the float hole 23, and the float 16 is insertedly connected with the float hole 23.

[0041] The inner side of the pot cover buckle tooth 12 is fixedly provided with a second air bag 6, the inner side of the pot cover buckle tooth 12 is fixedly provided with a first air bag 5, the inside of the pot cover buckle tooth 12 is provided with an air channel 2, and the first air bag 5 and the second air bag 6 are communicated through the air channel 2.

[0042] Working principle:

[0043] In use, Figure 1 As shown, the inner pot 1 is in a cover closing state. The inner pot 1 is arranged in the pot body assembly.

[0044] When the lid is closed, rotating the handle 3 causes the limiting frame 22 and the drive plate 8 to rotate. The rotation of the drive plate 8 causes the slider at the bottom of the movable plate 9 to slide along the drive guide groove 19, thereby pulling the lid latch 12 towards the axis of the lid 10. This positions the edge of the lid 10 and the latch 20 between the lid latch 12, thus closing the pressure cooker.

[0045] The first airbag 5 on the inner vertical surface of the lid buckle 12 first contacts the edge of the lid 10 and the pot tooth 20, and then squeezes the first airbag 5, so that the gas inside the first airbag 5 is discharged into the second airbag 6 through 2, causing the second airbag 6 to expand. Then, under the action of the first airbag 5 and the second airbag 6, the connection between the lid buckle 12 and the edge of the lid 10 and the pot tooth 20 becomes tighter.

[0046] When the inner pot 1 is heated and pressurized, the float 16 slides upward along the lid 10 into the float hole 23 under the pressure of the inner pot 1, thereby locking the movable plate 9. Under the action of the float 16, the movable plate 9 cannot be rotated, preventing the inner pot 1 from being opened under pressure, further preventing the possibility of the inner pot 1 being opened under pressure, and improving the safety of the device.

[0047] After the inner pot 1 is depressurized, the float 16 moves downward away from the float hole 23 and eventually moves down until the upper edge of the float 16 is exactly between the movable plate 9 and the pot lid 10, thereby releasing the restriction on the movable plate 9. The handle 3 is turned counterclockwise to make the limiting frame 22 rotate, and the driving plate 8 is rotated counterclockwise through the limiting frame 22. The rotation of the driving plate 8 causes the driving guide groove 19 to tilt, thereby causing the movable plate 9 to slide along the guide rod 11 through the guide groove 24 towards the outer edge of the driving plate 8 (i.e., the outer edge of the pot lid 10). At this time, the lower end of the pot lid fastener 12 moves to the edge of the pot lid 10, thereby opening the pot lid 10.

[0048] like Figure 9 As shown, when the lid is closed, the second spring 25 in the through groove 18 is in its original state. When the lid is opened, the movable plate 9 slides towards the outer edge of the drive disk 8, causing the second spring 25 to stretch. This causes the second spring 25 to contract when the lid is closed, assisting the movable plate 9 to move towards the axis of the drive disk 8.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
