Description

Technical Field

[0001] This utility model relates to the field of electric pressure cooker technology, specifically to an electric pressure cooker with adjustable pressure. Background Technology

[0002] Electric pressure cookers are an upgraded replacement for traditional pressure cookers and rice cookers. They combine the advantages of both, employing new technologies and structures such as elastic pressure control, dynamic sealing, an external rotating lid, and an adjustable displacement electric switch. They offer fully sealed cooking and continuously adjustable pressure, completely solving the safety issues associated with traditional pressure cookers and eliminating the safety hazards that have plagued consumers for years. Their thermal efficiency exceeds 80%, saving time and electricity (more than 30% more energy than ordinary rice cookers). However, existing electric pressure cookers also have drawbacks. The pressure is not adjustable; regardless of the amount of food in the inner pot, while the heating temperature is controllable, the heating pressure is uncontrollable, lacking user-friendliness and failing to meet the needs of current consumers. Utility Model Content

[0027] like Figure 1-4 As shown, an adjustable pressure electric pressure cooker includes:

[0028] The pot body 10 is provided with an inner cavity 101, and an inner liner 102 is provided inside the inner cavity 101. A first opening is provided on the inner cavity 101 for the inner liner 102 to enter.

[0029] A lid 20 is installed on the first opening, and the lid 20 is hinged to the pot body 10;

[0030] The pressure relief assembly 30 includes a connecting pipe 302, a plug 303, and a driving component. A pressure relief chamber 301 is provided on the pot lid 20. The top of the pressure relief chamber 301 has a second opening communicating with the outside. The pressure relief assembly 30 is installed inside the pressure relief chamber 301. The connecting pipe 302 penetrates the inner wall of the pressure relief chamber 301 and communicates the pressure relief chamber 301 with the inner cavity 101. The plug 303 is disposed inside the connecting pipe 302 and can be positioned relative to the connected component. The tube 302 slides, and the outer diameter of the plug 303 matches the inner diameter of the connecting tube 302. The plug 303 is placed on the end face of the connecting tube 302, which has an air tube 3032. The side of the plug 303 has a connecting hole 3033 that communicates with the air tube 3032. The driving member is adapted to drive the plug 303 to slide relative to the connecting tube 302 so that the tube wall of the connecting tube 302 can block or open the connecting hole 3033.

[0031] When this invention is in operation, the lid 20 is placed on the pot body 10 to seal the inner cavity 101. The steam generated during heating enters the pressure relief chamber 301 through the gas pipe 3032 and the connecting hole 3033, and flows out through the second opening at the top of the pressure relief chamber 301. During this process, to prevent the pressure inside the inner cavity 101 from being too low and thus failing to cook the food quickly, the plug 303 can be driven downward by the driving component, so that the connecting hole 3033 is partially submerged in the connecting pipe 302, thereby reducing the steam flow rate entering the pressure relief chamber 301 through the connecting hole 3033 and preventing the pressure inside the inner cavity 101 from dropping rapidly. When the pressure inside the inner cavity 101 is too high, the plug 303 can be driven upward by the driving component to increase the steam flow rate entering the pressure relief chamber 301 through the connecting hole 3033, thereby quickly reducing the pressure inside the inner cavity 101.

[0032] This utility model utilizes the connection pipe 302, the plug 303 and the driving component to cooperate, and the driving component drives the plug 303 to move within the connection pipe 302, thereby controlling the opening range of the connecting hole 3033, adjusting the flow rate of steam discharged from the connecting hole 3033, and thus achieving the purpose of regulating the pressure inside the inner cavity 101.

[0033] Specifically, in this embodiment, the driving component includes a toggle sleeve 304 and a driving sleeve 305. The toggle sleeve 304 is disposed inside the pressure relief chamber 301 and can move up and down relative to the pressure relief chamber 301. The plug 303 is fixedly connected to the side of the outer portion of the connecting pipe 302 with a sliding rod 3031. The end of the sliding rod 3031 is slidably connected to the inner wall of the pressure relief chamber 301. The toggle sleeve 304 is sleeved on the outside of the plug 303, and the side of the toggle sleeve 304 has an opening for the sliding rod 303. 1. A clearance hole 3041 is passed through. The bottom end of the drive sleeve 305 is sleeved on the outside of the actuating sleeve 304 and threadedly connected to the actuating sleeve 304, so as to facilitate the drive sleeve 305 to drive the actuating sleeve 304 to move up and down relative to the pressure relief chamber 301. The top end of the drive sleeve 305 extends out of the second opening and is provided with a rotating seat 306. The rotating seat 306 is rotatably connected to the second opening. The top end of the rotating seat 306 is provided with a pressure relief hole 3061 communicating with the pressure relief chamber 301.

[0034] During operation, the operator can rotate the drive sleeve 305 to drive the actuating sleeve 304 to move up or down. During the upward or downward movement of the actuating sleeve 304, the upper or lower edge of the clearance hole 3041 will abut against the slide rod 3031, and drive the plug 303 to move up or down, thereby controlling the gas flow rate into the pressure relief chamber 301.

[0035] In order to facilitate the movement of the sliding rod 3031 along with the toggle sleeve 304, in this embodiment, the inner wall of the clearance hole 3041 abuts against the sliding rod 3031, so that the sliding rod 3031 can move together with the toggle sleeve 304.

[0036] This configuration ensures that there is no gap between the actuating sleeve 304 and the slide bar 3031, thereby limiting the radial rotation of the actuating sleeve 304 and preventing the actuating sleeve 304 from rotating with the driving sleeve 305 during the movement of the driving sleeve 305.

[0037] Furthermore, in order to enable the pressure relief assembly 30 to automatically adjust the pressure relief speed according to the pressure inside the inner cavity 101 and avoid excessive pressure inside the inner cavity 101 that could damage the electric pressure cooker, in this embodiment, the pressure relief assembly 30 also includes an elastic element 308 and a fixed seat 309. The fixed seat 309 is disposed above the plug 303, and a fixed rod 3091 is disposed on the outer side of the fixed seat 309 and fixedly connected to the inner wall of the pressure relief chamber 301. The actuating sleeve 304 has a through hole for the fixed rod 3091 to pass through. The elastic element 308 is disposed between the fixed seat 309 and the plug 303, so that the elasticity of the elastic element 308 can be used to adjust the position of the plug 303 in the connecting pipe 302 to regulate the gas flow rate entering the pressure relief chamber.

[0038] Of course, the clearance hole 3041 can also be set to extend along the length direction of the actuating sleeve 304. This setting allows the slide bar 3031 to move back and forth along the length direction of the clearance hole 3041, thereby preventing the plug 303 from abutting against the actuating sleeve 304 and getting stuck during automatic adjustment.

[0039] In addition, to facilitate the user's rotation of the drive sleeve 305, in this embodiment, a rotating sleeve 307 extends downward from the outer side of the rotating seat 306. The rotating sleeve 307 is fitted onto the outer side of the pressure relief chamber 301 and is rotatably connected to the pressure relief chamber 301, so that the user can drive the drive sleeve 305 to rotate by rotating the rotating sleeve 307, while avoiding scalding the user when steam sprays out from the pressure relief hole 3061.

[0040] In order to improve the friction of the rotating sleeve 307, a friction surface is provided on the outer side of the rotating seat 306 in this embodiment.

[0041] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
