Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pressure cookers, and in particular to a fixing device, a handle, and a pressure cooker. Background Technology
[0002] A "micro pressure cooker" is a kitchen appliance that combines the features of a pressure cooker and a regular cookware. It adds a micro-pressure sealing function to traditional cookware (such as soup pots and stew pots), which can generate a pressure environment that is slightly higher than normal pressure cooking (usually lower than that of a traditional pressure cooker).
[0003] Chinese utility model patent CN222898969U disclosed on May 27, 2025, a micro pressure cooker with a quick-release handle, including a pot body and a pot lid. The pot lid is placed on top of the pot body. A pair of pot ears are provided on opposite sides of the pot body. The quick-release handle includes a lower side ear and an upper side ear. The lower side ear is detachably and movably mounted on the pot ear, and the upper side ear is detachably and movably mounted on the lower side ear. The upper side ear slides along the lower side ear to press or release the pot lid. This cookware features a simple structure with few parts, requiring no special tools and is easy to assemble and disassemble. Simply hold the upper side lug with one hand and move it horizontally. Moving it inwards presses the lid to increase and lock pressure, improving cooking efficiency. Moving it outwards releases the lid, allowing for pressure release. The side lugs feature a quick-release design, allowing for rapid separation and reassembly of the pot body. It maintains constant pressure inside the pot and automatically releases pressure when over-pressure occurs. While this patented method involves manually pushing the upper side lug to lock or unlock the lid, this method poses a risk of steam burns when the hand is close to the lid during unlocking.
[0004] Therefore, it is necessary to propose a micro pressure cooker that is less likely to burn hands. Summary of the Invention

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0029] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.
[0030] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.
[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0032] See Figure 1 This utility model provides a micro pressure cooker, which includes a pot body, a pot lid, and a handle provided on the pot body. A fixing device is used to fix the pot body and the pot lid. The fixing part 1 of the fixing device is installed on the handle, and the pressing part 2 presses down to press the pot lid when fully pressed down.
[0033] The pressing component 2 has different states. The fully pressed state is achieved when the pressing component 2 rotates counterclockwise to... Figure 2 In this state, the lid can be secured. Preferably, the pressing member 2 is in a horizontal state. Other states where the lid is not secured are considered incomplete pressing.
[0034] The fixing devices can be used not only for the pot body and lid, but also for securing other two components, such as boxes connected by hinges. Furthermore, the number of fixing devices can be selected according to actual requirements, preferably with a symmetrical distribution on both sides.
[0035] The following section describes the specific structure of the fixing device used to secure the lid and body of the pot.
[0036] See Figure 1-6 The fixing device includes a fixing member 1 and a pressing member 2 rotatably mounted on the fixing member 1 via a rotating shaft. The fixing member 1 has a locking block 11 that tends to move towards the pressing member 2. The fixing member 1 also has a button 12; when the button 12 is pressed down, it pushes the locking block 11 away from the pressing member 2. A torsion spring is mounted on the rotating shaft of the pressing member 2. When the pressing member 2 is fully pressed down, the locking block 11 blocks the pressing member 2, preventing it from rotating. Here, "fully pressed down" means the locking block blocks the pressing member, preventing further rotation. For better fixation of the lid, the pressing member 2 can also be positioned horizontally for "fully pressed down," with other states representing the lid being loosened.
[0037] Specifically, with Figure 2 For example, the locking block 11 moves back and forth within the fixing member 1. The locking block 11 has a protrusion 112 for locking the lower pressing member 2. When the locking block moves to the leftmost position, the protrusion 112 locks the lower pressing member 2. When the locking block moves to the right, the pressing member 2 can rotate clockwise under the action of the torsion spring. The button is used to control the locking block to move to the right, making operation simpler. Thus, when releasing the lower pressing member, there is no need to touch it with your hand. Pressing the button, which is further away from the lid, prevents burns from steam on the lid or contact with the lid.
[0038] Furthermore, see Figure 1 The fixing member 1 has a fixing part 13 on the side where the pressure member 2 is installed. The fixing part 13 is also provided with screw holes, through which the fixing device is fixed to the handle as a whole, and the handle is fixed to the pot body.
[0039] like Figure 2 The pressing component 2 includes a rotating part 21 and a pressure plate 22 disposed on the rotating part 21. The rotating part 21 is mounted on the fixing component 1 via a rotating shaft. The farthest end of the pressure plate 22 protrudes from the fixing component 1 when fully pressed down. After the fixing component 1 is fixed to the handle, the longer pressure plate 22 can better secure the pot lid.
[0040] The rotating part 21 is cam-shaped, meaning it is not a circle with a uniform radius everywhere; different radii are required to achieve fixation with the locking block. The rotating part 21 is provided with a locking surface 211, which is radially positioned to abut against the locking block 11 during rotation, preventing the rotating part 21 from rotating further.
[0041] See Figure 1 , Figure 3 and Figure 4 The rotating part 21 extends baffles 212 on both sides of the axial direction. The fixing member 1 is provided with shoulders 14 corresponding to the baffles 212. When the rotating part 21 is not in contact with the locking block 11, when the rotating part rotates clockwise (with... Figure 2 (For example, in the direction of rotation), the shoulder 14 can block the baffle 212 so that it no longer rotates clockwise, thus forming a limit.
[0042] For further details, please refer to [link / reference]. Figure 2 The fixing component 1 is L-shaped and is fixed to the pot body with the handle. It has no excessive protrusions, making it more aesthetically pleasing. The fixing component 1 has a cavity 15. The button 12 moves vertically along the cavity 15, and the locking block 11 moves horizontally along the cavity 15.
[0043] In an optional embodiment, see [link to relevant documentation] Figure 2 , Figure 5 and Figure 6 The locking block 11 is provided with a first inclined block 111, and the button 12 is provided with a second inclined block 121. The inclined surfaces of the first inclined block 111 and the second inclined block 121 correspond to each other and are always connected. With the first inclined block 111 and the second inclined block 121 corresponding to each other, when the button is pressed down, the locking block can move away from the pressing member 2.
[0044] Furthermore, see Figure 6 The locking block 11 has a first elastic element 113 at the end away from the pressing member 2. The elastic element 113 can be a spring or other elastic material, and is located on the side away from the pressing member 2. The elastic element 113 is always in contact with the inner wall of the cavity 15, so that the locking block always tends to move closer to the pressing member 2.
[0045] In an optional embodiment, see [link to relevant documentation] Figure 5 The button 12 has latches 122 on both sides and a second elastic element 123 at its bottom. A hollow guide post can be provided within the cavity 15. The second elastic element 123 can be a spring or other elastic material, and it moves up and down along the guide post. Alternatively, the second elastic element 123 can be omitted, and the button 12 can simply have a guide space for vertical movement. The latches 122 prevent the button from falling out of the cavity 15 and affecting its use.
[0046] Specific work process:
[0047] After placing the lid on the pot body, manually rotate the lower pressure piece 2 counterclockwise. Figure 2 (For example), after the snap-fit surface 211 of the rotating part 21 and the protrusion 112 abut against each other, the pressure plate 22 presses down on the pot lid, and the pressure plate 22 cannot be released automatically. At this time, the fixing device can fix the pot lid.
[0048] When you need to remove the pot lid, simply press button 12. The second inclined block 121 moves downward, pushing the first inclined block 111, causing the locking block 11 to move to the right. The pressing part 2 rotates clockwise under the action of the torsion spring, and the rotation no longer holds the pot lid in place. At this point, the pot lid can be removed. Direction determination is illustrated in example 2.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
