They are relative concepts and may change accordingly according to their different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in the present utility model can be understood according to the specific circumstances.

[0031] In some embodiments of the utility model, the cover body includes a cover body 1 and a cover handle 2 buckled with the cover body 1, the cover body 1 is provided with a plug hole 11 and at least two clamping holes 12, the at least two clamping holes 12 are spaced around the center line of the plug hole 11, the cover handle 2 is protrudingly provided with a plug column 21 and at least two clamping members 22, the plug hole 11 is for the plug column 21 to be plugged, a limit assembly is provided between the plug column 21 and the plug hole 11, the limit assembly is used to limit the rotation of the cover handle 2 relative to the clamping hole 12, the clamping member 22 is one by one with the clamping hole 12 Correspondingly, the fastener 22 can pass through the corresponding fastening hole 12, and the inner wall of each fastening hole 12 is provided with a non-return portion 121 and an elastic member 122. The non-return portion 121 and the elastic member 122 in the same fastening hole 12 are spaced apart and relatively distributed, and the gap between the non-return portion 121 and the elastic member 122 forms a fastening position 123, and the fastening position 123 is for the fastener 22 to pass through. When the cover handle 2 is buckled with the cover body 1, the fastener 22 is hooked with the non-return portion 121, and the elastic member 122 is pressed against the side of the fastener 22 away from the non-return portion 121.

[0032] Specifically, the cover body 1 is the main structural part of the cover body, and the cover handle 2 is buckled with the cover body 1 for the user to hold and operate the cover body. The plug hole 11 is provided on the cover body 1 for matching with the plug post 21 of the cover handle 2. At least two clamping holes 12 are provided, which are spaced around the center line of the plug hole 11. The plug post 21 is protrudingly provided on the cover handle 2 for inserting into the plug hole 11. At least two clamping parts 22 are provided, which are provided on the cover handle 2 and correspond to the clamping holes 12 one by one.

[0033] The limiting assembly is disposed between the plug-in column 21 and the plug-in hole 11 , and is used to limit the rotation of the cover handle 2 relative to the cover body 1 .

[0034] The check portion 121 is arranged on the inner side wall of the card hole 12, and is used to hook with the clip 22. The elastic member 122 is arranged on the inner side wall of the card hole 12, and is distributed opposite to the check portion 121, forming a clip position 123. The plug-in column 21 is protrudingly arranged on the cover handle 2. When the cover handle 2 is installed, the plug-in column 21 is inserted into the plug-in hole 11 on the cover body 1. The limit assembly is arranged between the plug-in column 21 and the plug-in hole 11 to ensure that the cover handle 2 can be accurately positioned and prevented from rotating when inserted. Each clip 22 corresponds to a card hole 12, and the clip 22 can pass through the corresponding card hole 12. The check portion 121 and the elastic member 122 are arranged in the card hole 12, forming a clip position 123. After the clip 22 passes through the card hole 12, the check portion 121 is hooked with the clip 22, and the elastic member 122 is pressed against the other side of the clip 22 to ensure a stable buckle. The plug-in column 21 of the lid handle 2 is inserted into the plug-in hole 11 of the lid body 1 to ensure the preliminary connection between the lid handle 2 and the lid body 1 .

[0035] The latch 22 of the lid handle 2 passes through the latch hole 12 of the lid body 1 through the plug-in action, and forms a buckle connection through the check portion 121 and the elastic member 122. The plug-in column 21 is inserted into the plug-in hole 11, and is precisely positioned under the action of the limit assembly to prevent the lid handle 2 from rotating. After the latch 22 passes through the latch hole 12, the check portion 121 hooks with the latch 22, and the elastic member 122 provides additional pressure to ensure a tight buckle connection. When the user applies force to pull out the lid handle 2, the latch 22 is blocked by the check portion 121 to prevent it from falling out, and at the same time, the elastic member 122 maintains pressure to ensure a stable connection.

[0036] Operation steps: Align the cover handle 2 with the plug hole 11 of the cover body 1. Insert the plug post 21 into the plug hole 11 to ensure that the limit assembly is effective to prevent rotation. Continue to apply force to ensure that the buckle 22 passes through the corresponding buckle hole 12. After the buckle 22 passes through the buckle hole 12, the check part 121 hooks with the buckle 22, and the elastic member 122 provides pressure to ensure stability. Confirm that the cover handle 2 is tightly buckled with the cover body 1.

[0037] Technical effect: The hooking of the check portion 121 and the snap member 22, as well as the tightening effect of the elastic member 122, ensures that the cover handle 2 is firmly buckled on the cover body 1. The matching design of the plug-in column 21 and the plug-in hole 11 facilitates installation and removal operations, while the limit assembly ensures correct positioning. The limit assembly limits the rotation of the cover handle 2 relative to the cover body 1, increasing the safety and reliability of use. The elastic member 122 provides continuous pressure to ensure long-term stability of the connection, and remains stable even after multiple operations.

[0038] In addition, the materials of the lid handle 2 and the lid body 1 can be selected according to different application requirements, such as plastic, metal, etc., to meet different strength and durability requirements. The elastic member 122 can also be made of different elastic materials, such as rubber, spring, etc., and the elastic strength can be adjusted as needed.

[0039] In some embodiments of the present invention, the buckle 22 is provided with an anti-drop hook 221 protruding toward the elastic member 122 , and the upper side of the anti-drop hook 221 is pressed against the bottom of the elastic member 122 to prevent the buckle 22 from falling out of the buckle hole 12 .

[0040] Specifically, the anti-drop hook 221 is a raised portion on the latch 22 , which is usually designed to be hook-shaped or protruding so as to interact with the elastic member 122 after being inserted into the latch hole 12 to prevent the latch 22 from escaping from the latch hole 12 .

[0041] When the anti-detachment hook 221 is a hook-shaped structure, the upper side of the anti-detachment hook 221 is curved, which is convenient for fixation under the pressure of the elastic member 122 .

[0042] When the anti-disconnection hook 221 is a protruding structure, the protruding structure is a protruding portion facing the elastic member 122 , and is used to press against the bottom of the elastic member 122 after the buckle member 22 is fully inserted.

[0043] The anti-disconnection hook 221 is located on the latch 22, arranged on the side of the latch 22, and protrudes toward the elastic member 122. Its specific position allows the anti-disconnection hook 221 to just contact and press against the bottom of the elastic member 122 when the latch 22 passes through the latch hole 12 and hooks with the non-return portion 121. The reaction force provided by the elastic member 122 makes the anti-disconnection hook 221 close to its bottom, forming an additional fixing point. This ensures that even if the cover handle 2 is subjected to external force in the pulling-out direction, the latch 22 will not easily disengage from the latch hole 12, because the presence of the anti-disconnection hook 221 provides additional resistance. The anti-disconnection hook 221 ensures a tight connection between the cover handle 2 and the cover body 1, avoids looseness, and improves reliability during use.

[0044] Preferably, the number of the locking members 22 and the number of the locking holes 12 are both three.

[0045] Specifically, the distribution of the three snap members 22 and the snap holes 12 can make the connection between the cover handle 2 and the cover body 1 more stable and balanced, disperse the force, improve the reliability of the overall structure, and better withstand various external forces during use. Secondly, compared with the case with a smaller number, the setting of the three snap members 22 increases the contact points and fixing points of the buckle, further enhancing the tightness and stability of the connection between the cover handle 2 and the cover body 1, which is not easy to loosen or fall off.

[0046] Of course, in other examples, the number of the fasteners 22 and the fastener holes 12 can be flexibly adjusted as needed, and the number of the fasteners 22 and the fastener holes 12 is not specifically limited herein.

[0047] In some embodiments of the utility model, the limiting assembly includes at least two limiting ridges 23 and at least two limiting grooves 13, the length direction of the limiting ridges 23 and the length direction of the limiting grooves 13 are parallel to the axial center line of the plug-in hole 11, and the cover handle 2 is inserted into the plug-in hole 11 under the cooperation of the limiting ridges 23 and the limiting grooves 13.

[0048] Specifically, the limiting convex strip 23 is usually a long strip protrusion, the length direction of which is parallel to the axis of the plug-in hole 11, and the cross-section can be rectangular, semicircular or other suitable shapes to ensure that it can match the limiting groove 13 during the plug-in process. The limiting groove 13 is a long strip groove that matches the shape of the limiting convex strip 23, the length direction of which is also parallel to the axis of the plug-in hole 11, and the cross-sectional shape corresponds to the limiting convex strip 23. The limiting convex strip 23 is arranged on the plug-in column 21 of the cover handle 2, and is distributed along the length direction of the plug-in column 21. Usually, at least two limiting convex strips 23 are evenly distributed on the periphery of the plug-in column 21. The limiting groove 13 is arranged on the inner wall of the plug-in hole 11 of the cover body 1, and the position corresponds to the limiting convex strip 23, ensuring that the limiting convex strip 23 can slide smoothly into the limiting groove 13 when the plug-in column 21 is inserted into the plug-in hole 11. The plug-in column 21 of the cover handle 2 is aligned with the plug-in hole 11 of the cover body 1, so that the limiting convex strip 23 is aligned with the limiting groove 13. The plug-in column 21 is inserted into the plug-in hole 11, and the limiting convex strip 23 slides along the limiting groove 13 to ensure that the plug-in column 21 can smoothly enter the plug-in hole 11. When the plug-in column 21 is fully inserted into the plug-in hole 11, the cooperation of the limiting convex strip 23 and the limiting groove 13 limits the rotation of the cover handle 2. The cooperation design of the limiting convex strip 23 and the limiting groove 13 enables the cover handle 2 to be accurately aligned with a specific angle when inserted into the cover body 1, thereby preventing the cover handle 2 from rotating after installation. The limiting convex strip 23 slides along the limiting groove 13 during the insertion process, providing a good guiding effect, ensuring a smooth and accurate plug-in process. The presence of the limiting assembly enhances the connection stability between the cover handle 2 and the cover body 1, ensuring that the snap-on member 22 is accurately matched with the snap-on hole 12. The cooperation between the limiting convex strip 23 and the limiting groove 13 effectively limits the rotation of the lid handle 2 relative to the lid body 1, ensuring the stable cooperation between the latch 22 and the latch hole 12. The cooperation between the limiting convex strip 23 and the limiting groove 13 ensures the precise positioning of the lid handle 2 during installation, improving the installation accuracy. The setting of the limiting assembly increases the connection strength between the lid handle 2 and the lid body 1, making the overall structure more stable. The limiting assembly provides a clear guide, making the installation operation of the lid handle 2 easier and more efficient.

[0049] In some embodiments of the utility model, at least two limiting protrusions 14 are protruding from the cover body 1, and a limiting protrusion 14 is provided between any two adjacent card holes 12. All the limiting protrusions 14 are spaced apart around the center line of the plug-in hole 11, and a limiting arc groove 24 is formed between any two snap fasteners 22. The limiting arc grooves 24 correspond one-to-one to the limiting protrusions 14, and the two ends of the limiting protrusion 14 are respectively pressed against the two ends of the corresponding limiting arc grooves 24.

[0050] Specifically, when the plug-in column 21 of the cover handle 2 is inserted into the plug-in hole 11 of the cover body 1, the limiting protrusion 14 on the cover body 1 will enter the corresponding limiting arc groove 24 on the cover handle 2, and the two ends of the limiting protrusion 14 will be tightly against the two ends of the limiting arc groove 24. Through the cooperation between the limiting protrusion 14 and the limiting arc groove 24, the rotation of the cover handle 2 in the circumferential direction relative to the cover body 1 can be further limited, the stability and reliability of the cover handle 2 after being connected to the cover body 1 are enhanced, and unnecessary shaking or rotation during use is prevented, ensuring the firmness of the cover structure and the safety of use. At the same time, this design also helps with precise positioning and installation, making the buckling operation of the cover handle 2 and the cover body 1 more accurate and smooth.

[0051] In some embodiments of the utility model, a first guiding slope 222 is provided on the latch 22, and a second guiding slope 1211 cooperating with the first guiding slope 222 is provided on the check portion 121. The latch 22 passes through the latch hole 12 under the guidance of the first guiding slope 222 and the second guiding slope 1211.

[0052] Specifically, the first guide slope 222 is a slope located at the front end of the latch 22, and is usually in a smooth slope shape, so as to guide the latch 22 into the latch hole 12 during the insertion process. The first guide slope 222 is arranged at the front end of each latch 22, facing the plug hole 11 of the cover body 1. The second guide slope 1211 is a slope located on the non-return portion 121, matching with the first guide slope 222, and is usually also in a smooth slope shape, so as to cooperate with the first guide slope 222. The second guide slope 1211 is arranged on the non-return portion 121 of each latch hole 12, parallel to the inner side wall of the latch hole 12, and facing the direction of the latch 22.

[0053] When the plug-in column 21 of the cover handle 2 is inserted into the plug-in hole 11 of the cover body 1, the first guide bevel 222 at the front end of the clip 22 first contacts the second guide bevel 1211 of the check portion 121 in the clip hole 12. During the plug-in process, the first guide bevel 222 slides along the second guide bevel 1211 to guide the clip 22 to smoothly pass through the clip position 123 of the clip hole 12. The design of the first guide bevel 222 and the second guide bevel 1211 provides a good guiding effect, so that the clip 22 can smoothly slide through the check portion 121 and enter the clip hole 12 during the insertion process. The design of the guide bevel reduces the resistance of the clip 22 during insertion and prevents jamming or damage during the plug-in process. The bevel guide ensures that the clip 22 can automatically align to the correct position after entering the clip hole 12, and ensures that the clip 22 can accurately cooperate with the check portion 121 and the elastic member 122. Guided by the guide bevel, the fastener 22 can smoothly pass through the fastener hole 12, avoiding the jamming phenomenon during the installation process and improving the installation efficiency. After the fastener 22 enters the fastener hole 12, the cooperation of the first guide bevel 222 and the second guide bevel 1211 enables the fastener 22 to automatically align and hook with the non-return portion 121, ensuring the secure buckling of the cover handle 2 and the cover body 1. The design of the bevel reduces the friction between the fastener 22 and the inner wall of the fastener hole 12, effectively reducing the wear between the components and extending the service life of the device.

[0054] In some embodiments of the present invention, a buckle head 223 protruding toward the non-return portion 121 is provided on the buckle member 22 , and the upper part of the buckle head 223 is pressed against the bottom of the non-return portion 121 to prevent the buckle member 22 from falling out of the buckle hole 12 .

[0055] Specifically, the buckle head 223 protrudes toward the direction of the non-return portion 121, and is usually triangular or trapezoidal, so that it can be firmly matched with the non-return portion 121. The buckle head 223 has a plane or a slightly curved surface above it, which is tightly abutted against the bottom of the non-return portion 121. The protruding direction of the buckle head 223 is opposite to the position of the non-return portion 121, so that it can form a firm connection with the non-return portion 121 when the cover handle 2 is buckled. When the cover handle 2 is installed, the buckle 22 passes through the clamping hole 12, and the front end of the buckle head 223 first contacts the non-return portion 121. When the buckle 22 completely passes through the clamping hole 12, the upper plane of the buckle head 223 is tightly abutted against the bottom of the non-return portion 121 to form a buckle connection. When the cover handle 2 is pressed downward, the first guide slope 222 of the buckle 22 guides the buckle 22 to pass through the clamping hole 12 smoothly. When the buckle 22 completely enters the hole 12, the protruding portion of the buckle head 223 passes through the buckle position 123 in the hole 12 and finally abuts against the bottom of the non-return portion 121. The buckle head 223 is designed so that its upper plane can fit tightly against the bottom of the non-return portion 121 to prevent it from sliding upward or falling out.

[0056] In some embodiments of the present invention, an insertion end 224 is disposed at the bottom end of the locking member 22 , and the insertion end 224 is chamfered with an arc transition.

[0057] Specifically, the insertion end 224 is in a circular arc chamfer transition, that is, its end is in a circular arc shape. This design makes the insertion end 224 smooth and has no sharp edges, which is conducive to smooth insertion and passing through the clamp hole 12. The circular arc chamfer can be in the shape of a partial sphere or a cylindrical surface, depending on the design requirements. The insertion end 224 is located at the bottom end of the clamp 22, that is, the end portion of the clamp 22. This portion is the portion that first contacts the inner wall of the clamp hole 12 when the clamp 22 is inserted into the clamp hole 12.

[0058] When the cover handle 2 is pressed downward, the insertion end 224 of the latch 22 first enters the hole 12. The design of the circular chamfer allows the insertion end 224 to smoothly contact the inner wall of the hole 12 when inserted into the hole 12, and gradually guides the entire latch 22 into the hole 12. The circular chamfer transition of the insertion end 224 cooperates with the smooth transition surface of the inner wall of the hole 12 to achieve smooth insertion and reduce insertion resistance. The circular chamfer design allows the latch 22 to be inserted into the hole 12 more smoothly, reduces insertion resistance and jamming, and improves assembly efficiency. Even in the case of imprecise operation, the circular arc shape of the insertion end 224 can effectively guide the latch 22 into the hole 12, reducing the wear on the hole 12 and the latch 22. The circular chamfer design reduces the wear of the latch 22 on the inner wall of the hole 12, thereby extending the service life of the cover body. During the insertion and buckling process, the smooth transition surface of the insertion end 224 can protect the inner wall of the card hole 12 from being scratched or damaged.

[0059] In some embodiments of the present invention, a metal piece (not shown) is provided on the surface of the cover body 1 away from the cover handle 2 , and a through hole 25 is provided through the plug-in column 21 , and a screw passes through the through hole 25 to connect with the cover body 1 .

[0060] Specifically, in the cover body, the screw passes through the through hole 25 on the plug-in column 21, and then the cover body 1 is connected to the metal part. In this way, the cover body and the metal part are easily fixed together. In this embodiment, the cover body 1 and the cover handle 2 are not plastic parts. By setting the metal part on the surface of the cover body 1 away from the cover handle 2, it can accurately cover the plastic part on the cover body 1. The metal part plays a role of isolation and protection, avoiding direct exposure of the plastic part, thereby reducing the potential health risks that may be caused by the plastic part, and this connection method using screws can ensure that this performance can be stably exerted. The stability of the cover body is improved as a whole, ensuring that it can play a better role during use.

[0061] In some embodiments of the present invention, the kettle comprises a kettle body and a cover body in any one of the above embodiments, and the cover body is used to cover the opening on the top of the kettle body.

[0062] The utility model provides a check portion 121 and an elastic member 122 on the clamping hole 12, so that the clamping member 22 is more stable and not easy to be separated when subjected to force; at the same time, the assembly process is simplified, screw fixing is omitted, and the assembly cost and time are reduced.
