[0002] Electric slow cookers are currently the most widely used slow cooking appliances in homes, businesses, restaurants, and other establishments. Slow cookers typically use electric heating to heat a heating plate at the bottom of the pot, generating even heat. Slow cookers have a long heating time, usually set to 4 to 8 hours or longer. The lid is usually sealed to the pot to prevent steam escape and maintain a stable temperature and humidity inside. The lid also seals the pot, preventing spills when taken outdoors for camping, making it very convenient to use.

[0003] Chinese patent document CN201721014314.2 discloses a slow cooker with a locking structure. The hook is placed on the latch in a movable, unlocked state. Then, the folding part is flipped upwards, and the cam rotates clockwise under the pull of the folding part. The mounting post pulls the hook downwards until the folding part returns to a horizontal position, tightening the hook and latch to lock the lid and press against the sealing ring between the lid and the pot body, forming a sealed lid and preventing spillage. However, when unlocking is needed, the locking structure cannot provide an effective grip to quickly remove the hook. Furthermore, the locking structure cannot provide a sturdy support point for moving the slow cooker; a separate handle needs to be installed on the pot body as a support point, resulting in a complex overall structure and increased cost.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a slow cooker, including a pot body 1, a pot lid 2, and a locking assembly. The pot lid 2 covers the pot body 1. Two locking assemblies are provided, symmetrically arranged on the outer periphery of the pot body 1. Each locking assembly includes a fixing base 31, a plate buckle 32, and a hook 33. The fixing base 31 is located on the outer periphery of the pot body 1. One end of the plate buckle 32 is hinged to the fixing base 31 through a first hinge point 11, and the other end is free. The hook 33... 33 is hinged to the plate buckle 32 through the second hinge point 12, the second hinge point 12 being located between the first hinge point 11 and the free end. The plate buckle 32 is used to rotate around the first hinge point 11 so that the hook buckle 33 is driven by the second hinge point 12 to lock the pot lid 2 onto the pot body 1. The hook buckle 33 is provided with a gripping part 331, which extends away from the pot lid 2 and can be gripped by the hand.

[0023] In the locked state, the second hinge point 12 is located below the first hinge point 11. The plate buckle 32, through the cooperation of the fixing seat 31, the first hinge point 11, and the second hinge point 12, secures the hook 33 onto the pot lid 2. The pot lid 2 is compressed by the locking assembly, resulting in an upward prestress that causes the hook 33 to interfere with the edge of the pot body 1, preventing the lid assembly from opening. Due to the tight fit between the pot lid 2 and the pot body 1, the pot lid 2 seals the edge of the pot body 1, thereby preventing the soup from overflowing and preventing the pot lid 2 from falling off.

[0024] Because the hook 33 in this application is equipped with a grip 331, when the slow cooker needs to be moved, the slow cooker can be moved simply by holding the grip 331, eliminating the need for a separate handle on the pot body 1 to provide a support point. When moving the slow cooker, the end of the hook 33 that is pressed against the lid 2 receives upward pressure from the lid 2, and the grip 331 also receives upward pressure from the hand. Meanwhile, the hook 33 receives downward pressure at the second hinge point 12. This downward pressure cancels out the two upward pressures, achieving a force balance and preventing the hook from coming undone during the movement of the slow cooker using the grip 331. Furthermore, the locking assembly of this application has a simple structure, consisting of only a few parts, which greatly reduces production costs while maintaining practicality.

[0025] It is worth noting that, such as Figure 5As shown, the locking assembly of this application is also applicable to the pot body 1 with a handle 13. Since the pot body 1 is provided with a handle 13, the user can choose either the grip 331 or the handle 13 as a support point. For example, if the pot body 1 contains a large amount of soup, the handle 13 can be chosen as the support point. Alternatively, when it is not necessary to close the lid 2 onto the pot body 1, and only the pot body 1 needs to be moved, the handle 13 can provide a support point for moving the pot body 1.

[0026] Furthermore, a sealing ring can be provided on the lid 2. When the hook 33 locks the lid 2, the sealing ring is compressed by the locking assembly, creating an upward prestress. This causes the hook 33 to interfere with the edge of the pot body 1. The elasticity of the sealing ring itself creates a sealed space between the pot body 1 and the sealing ring, thus preventing soup from spilling and the lid from falling off. The sealing ring further enhances the sealing performance between the lid 2 and the pot body 1.

[0027] Specifically, when locking is required, first place the lid 2 on the pot body 1, with the fixing base 31, plate buckle 32, and hook buckle 33 in a free state. Rotate the hook buckle 33 around the second hinge point 12 and push it above the lid 2. Rotate the plate buckle 32 in the opposite direction. Before the free end of the plate buckle 32 rotates around the first hinge point 11 to the point where its movement trajectory is farthest from the pot body 1, the lid 2 is not subjected to any force from the hook buckle 33. After the free end of the plate buckle 32 has rotated past the point where its movement trajectory is farthest from the pot body 1, the second hinge point 12 causes the hook buckle 33 to press against the lid 2, and under the prestress of the sealing ring, the hook buckle 33 interferes with the edge of the pot body 1. When the plate buckle 32 rotates to its lowest point, the lid 2 and the pot body 1 are locked.

[0028] To open the pot lid 2, first move the buckle 32 from bottom to top, so that the buckle 32 rotates around the first hinge point 11. After the free end of the buckle 32 rotates around the first hinge point 11 to the point where its movement trajectory is farthest from the pot body 1, the upward prestress of the sealing ring disappears. Then, rotate the hook 33 around the second hinge point 12 and push it to the top away from the pot lid 2, so that the pot lid 2 can be easily removed.

[0029] In one feasible embodiment, the hook 33 is provided with a protrusion 332, which is located on the side away from the gripping part 331. The pot lid 2 is provided with a flange 21 that mates with the protrusion 332. The protrusion 332 is pressed onto the flange 21 to lock the pot lid 2 onto the pot body 1. In this embodiment, the protrusion 332 extends downward and the flange 21 extends upward. A snap-fit ​​surface is formed on the side of the protrusion 332 near the flange 21, and a guide slope is formed on the other side. The snap-fit ​​surface is used to abut against the flange 21 to hook the flange 21, and the guide slope guides the protrusion 332 when the hook 33 enters above the pot lid 2.

[0030] In one feasible embodiment, the grip portion 331 is recessed with a concave surface 3311 and an arc-shaped surface 3312. The arc-shaped surface 3312 is located below the concave surface 3311. The concave surface 3311 is used to accommodate the thumb of the hand, and the arc-shaped surface 3312 is used to abut against the other four fingers of the hand. In this embodiment, the concave surface 3311 serves a positioning and anti-slip function, ensuring that the thumb can be accurately placed on the grip portion 331 when transferring the slow cooker, and providing anti-slip protection. The arc-shaped surface 3312 is designed to better adapt to the natural grip of the hand, especially when using heavy cookware such as slow cookers. The arc-shaped grip portion 331 reduces pressure on the fingers, making it more comfortable to hold and less likely to cause hand fatigue. The arc design also helps to improve the stability and structural strength of the hook 33. Appropriate bending can distribute the force acting on the hook 33, making it less prone to deformation or breakage when bearing heavy objects.

[0031] In one feasible implementation, the hook 33 includes a connecting handle 333, one end of which is connected to the gripping part 331, and the other end is connected to the plate buckle 32 via the second hinge point 12.

[0032] Furthermore, the buckle 32 has a notch 321, and both the first hinge point 11 and the second hinge point 12 are located within the notch 321. One end of the connecting handle 333 extends into the notch 321 and is connected to the buckle 32 via the second hinge point 12. The notch 321 provides accommodating space for the first hinge point 11 and the second hinge point 12, reducing the overall size of the buckle 32.

[0033] In one feasible embodiment, the connecting handle 333 has a first recess 3331 recessed on the side near the fixing seat 31. The first recess 3331 is used to accommodate the first hinge point 11 after the hook 33 locks the lid 2 onto the pot body 1. This embodiment is suitable for fixing seats 31 that protrude outwards from the pot body 1. The first recess 3331 allows the connecting handle 333 to adapt to the shape of the fixing seat 31 and also allows for a better fit to the fixing seat 31.

[0034] In one feasible embodiment, the connecting handle 333 has a plurality of reinforcing ribs 3332 protruding from the side away from the fixing base 31, and the reinforcing ribs 3332 extend vertically. In this embodiment, the reinforcing ribs 3332 can ensure that the connection strength of the connecting handle 333 is improved while greatly reducing the material required to manufacture the locking assembly, thereby reducing production costs.
