[0001] This utility model relates to the field of kettle technology, and more specifically to a kettle lid locking structure, a kettle lid, and a kettle. Background Technology
[0002] As an indispensable household appliance, the electric kettle provides hot water conveniently and quickly, and is used in every home and office. However, most electric kettles on the market currently open their lids by pressing a button on the handle. This button is mounted on the handle via a connector, and the lid is connected to a lid lock mechanism inside the handle on one side. For example, CN212140224U discloses a kettle lid lock assembly structure, including a bracket, a connector, and a locking key. The connector has two arm beams forming a symmetrical U-shaped structure, with shaft holes on the inner walls of both arm beams. The locking key has shaft heads on both sides, positioned between the two arm beams so that the two shaft heads are rotatably mounted in their respective shaft holes. The connector is fixedly connected to the bracket, which has anti-deformation terminals clamped between the two arm beams. While this prior art ensures the stability of the connector, improves the structural strength between the locking key and the connector, and prevents lid lock failure, it is a single-sided lock with poor sealing, and its complex structure consists of multiple parts. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a kettle lid lock structure, a kettle lid and a kettle, which has a simple structure and high reliability.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a lid lock structure, including a lid opening knob, a connecting rod and a cam arranged sequentially from top to bottom, a lid lock provided on the side of the cam, and a locking tongue provided at the outer end of the lid lock; the lid opening knob is set on the top surface of the lid, the connecting rod is connected to the lower end of the lid opening knob, and a return spring is provided between the cam and the connecting rod; when the lid opening knob is in the pressed state, the connecting rod is connected to the cam, and the cam can be driven to rotate by the lid opening knob, so that the locking tongue on the lid lock retracts or extends relative to the lid; when the cam is in the open position, the locking tongue retracts and is in a state of separation from the lid body; when the cam is in the locked position, the locking tongue extends outward to the outside of the side wall of the lid and is in a state of locking with the lid body.
[0005] This technical solution provides a kettle lid lock structure that utilizes the linkage between a switch knob, a connecting rod, a cam, and a lock lid with a locking tongue. By pressing and rotating the lid opening knob, the kettle lid can be opened and locked. It has fewer components, a simpler structure, higher reliability, and can extend the service life of the kettle lid lock.
[0006] In a preferred embodiment, when the lid-opening knob is not pressed, the linkage is disengaged from the cam. In this technology, the lid lock position does not change when the lid-opening knob is not pressed, thus the state of the locking tongue remains unchanged, allowing the lid to remain in either the unlocked or locked state.
[0007] In a preferred embodiment, the lid locking structure includes at least two lid locks, each symmetrically arranged around the center point of the cam. A guide rail is also provided on the bottom surface of the lid to slide against the lid locks, allowing the lid locks to slide radially back and forth along the cam. This technology, by using at least two lid locks in the lid locking structure, achieves multi-point locking of the lid, resulting in a more secure lock and a better sealing effect.
[0008] In a preferred embodiment, the lid locking structure includes two lid locks, and the cam is elliptical in shape; the two lid locks are symmetrically arranged on both sides of the cam. This technology uses an elliptical cam and two lid locks in combination to achieve double-sided locking of the lid, which is secure, has good sealing performance, and is simple in structure, thus reducing production costs.
[0009] In a preferred embodiment, the lid lock includes a slider and a latch mounting block connected by a lid lock spring. The slider is slidably mounted on a guide rail, and the latch is located on the outer end face of the latch mounting block. An opening for the latch to extend is provided on the side wall of the lid. This technology, by incorporating a lid lock spring, provides stable support for the lid lock while ensuring the slider can automatically reset. The structure is simple, stable, and reliable.
[0010] Furthermore, the outer end face of the latch mounting block is an arc-shaped surface, and at least two latch portions are symmetrically provided on the outer end face of the latch mounting block, making the locking more secure.
[0011] In a preferred embodiment, the upper end face of the connecting rod is provided with multiple protrusions, and the inner side of the top surface of the lid is provided with multiple grooves that mate with the protrusions. When the lid-opening knob is not pressed, the protrusions are inserted into the grooves, locking the connecting rod inside the top surface of the lid, further improving the stability of the lid-locking structure. Furthermore, four protrusions are evenly distributed circumferentially on the upper end face of the connecting rod, resulting in a simple structure and a stable fit.
[0012] A kettle lid includes a lid locking structure as described in any of the above technical solutions. The kettle lid in this technology, employing the aforementioned lid locking structure, offers convenient opening and closing, high reliability, and a longer service life.
[0013] A kettle includes a kettle body and a lid as described in the above-described technical solution.

[0030] Reference Figure 1-9 This invention describes a kettle lid locking structure, a kettle lid, and a kettle according to an embodiment of the present invention. The kettle can be an electric kettle, a thermos kettle, or other types of kettles.
[0031] In one embodiment, such as Figure 1-7 As shown, a lid lock structure includes a lid opening knob 1, a connecting rod 2 and a cam 3 arranged sequentially from top to bottom. A lid lock 4 is provided on the side of the cam 3, and a locking tongue 40 is provided at the outer end of the lid lock 4.
[0032] The lid opening knob 1 is located on the top surface of the lid 100, the connecting rod 2 is connected to the lower end of the lid opening knob 1, and a return spring 5 is provided between the cam 3 and the connecting rod 2;
[0033] When the lid opening knob 1 is in the pressed state, the connecting rod 2 is connected to the cam 3. The cam 3 can be rotated by the lid opening knob 1 so that the locking tongue 40 on the lid lock 4 retracts or extends relative to the lid 100.
[0034] When the cam 3 is in the open position, the locking tongue 40 retracts and is separated from the body 200. At this time, the lid 100 is unlocked from the body 200, and the user can remove the lid 100 from the body 200.
[0035] When the cam 3 is in the locked position, the locking tongue 40 extends outward to the outside of the side wall of the lid 100 and is locked to the body 200. At this time, the lid 100 is locked to the body 200, and the user cannot remove the lid 100 from the body 200.
[0036] The lid-opening knob 1 is a rotatable button, with its upper end exposed on the top surface of the lid 100 for the user to press and rotate. The connecting rod 2 can be fixedly connected to the lower end of the lid-opening knob 1; it can be an independent connecting rod structure or an integrally formed structure with the lid-opening knob 1. When the lid-opening knob 1 is pressed, the rotating shaft of the cam 3 inserts into the connecting hole at the bottom of the connecting rod 2, thus achieving a mating connection. The shape of the cam 3 is not limited, as long as its outer peripheral sidewall can drive the lid lock 4 to move inward or outward when the cam 3 rotates, so that the locking tongue 40 retracts or extends relative to the lid 100. The number of lid locks 4 varies depending on the shape of the cam 3; it can be one or more. For example, when the cam 3 is elliptical, there are two lid locks 4; when the cam 3 is star-shaped, there can be 3 to 4 lid locks 4. Each lid lock 4 corresponds to one tooth of the cam 3. When the top of the tooth of the cam 3 abuts against the lid lock 4, the cam 3 is in the locked position. At this time, the lid lock 4 moves to the last position, and the locking tongue 40 extends outward to the outside of the side wall of the lid 100 and locks with the port of the pot body 200.
[0037] In practice, when the lid 100 is in the locked state, the lid opening knob 1 is pressed. Since the connecting rod 2 is connected to the lid opening knob 1, rotating the lid opening knob 1 can drive the connecting rod 2 and the cam 3 to rotate. When the cam 3 rotates to the open position, the side lid lock 4 moves inward, causing the locking tongue 40 to retract inward, and the lid 100 separates from the pot body 200. Then, the lid opening knob 1 is released, and the connecting rod 2 returns to its original position under the elastic force of the return spring 5. The lid lock 4 and its locking tongue 40 remain in the same position, keeping the lid 100 in the open state.
[0038] When the lid 100 is in the open position, the lid opening knob 01 is pressed, and the connecting rod 02 is connected to the cam 03. Rotating the lid opening knob 1 can drive the connecting rod 2 and the cam 3 to rotate. When the cam 3 rotates to the locked position, the side lid lock 4 moves outward, causing the locking tongue 40 to extend outward to the outside of the side wall of the lid 100, so that the locking tongue 40 locks the lid body 200. Then, the lid opening knob 1 is released, and the connecting rod 2 returns to its original position under the elastic force of the return spring 5. The lid lock 4 and its locking tongue 40 remain in the same position, so that the lid 100 is kept in the locked position.
[0039] The lid lock structure in the above embodiment can open and lock the lid 100 by pressing and rotating the lid opening knob 1. It has fewer components, a simpler structure, higher reliability, and can extend the service life of the lid lock.
[0040] In this embodiment, when the cover opening knob 1 is not pressed, the connecting rod 2 is separated from the cam 3.
[0041] When the lid opening knob 1 is not pressed, the lid lock 4 remains in the same position, so that the state of the locking tongue 40 remains unchanged. That is, the locking tongue 40 will always be in a state of being separated from or locked from the pot body 200 until the lid opening knob 1 is pressed and rotated next time.
[0042] In this embodiment, the lid locking structure includes at least two lid locks 4, each lid lock 4 being symmetrically arranged around the center point of the cam 3; the bottom surface of the lid 100 is also provided with a guide rail that slides with the lid lock 4, and the lid lock 4 can slide back and forth radially along the cam 3 via the guide rail. By providing at least two lid locks 4, the lid locking structure can achieve multi-point locking of the lid 100, resulting in a more secure lock and a better sealing effect.
[0043] In this embodiment, the above-mentioned lid lock structure includes two lid locks 4, and the cam 3 is elliptical in shape; the two lid locks 4 are symmetrically arranged on both sides of the cam 3.
[0044] In practice, when the two ends of the elliptical major axis of the cam 3 abut against the two lid locks 4 respectively, the two lid locks 4 move outward, so that the locking tongue 40 extends outward to lock with the pot body 200, and the cam 3 is in the lid-locked position; when the elliptical minor axis of the cam 3 is between the two lid locks 4, the two lid locks 4 move inward, so that the locking tongue 40 retracts inward and separates from the pot body 200, and the cam 3 is in the lid-open position.
[0045] In this embodiment, the lid lock 4 includes a slider 42 and a latch mounting block 43 connected by a lid lock spring 41. The slider 42 is slidably mounted on a guide rail, and the latch portion 40 is located on the outer end face of the latch mounting block 43. An opening for the latch portion 40 to extend is provided on the side wall of the lid 100. The lid lock spring 41 is used to ensure that the slider 42 can automatically reset and to provide support force to the latch mounting block 43.
[0046] In this embodiment, the outer end face of the latch mounting block 43 is an arc-shaped surface, and at least two latch portions 40 are symmetrically provided on the outer end face of the latch mounting block 43, making the locking more stable.
[0047] In this embodiment, the upper end face of the connecting rod 2 is provided with a plurality of protrusions 21, and the inner side of the top surface of the lid 100 is provided with a plurality of grooves 101 that cooperate with the plurality of protrusions; when the lid opening knob 1 is in the non-pressed state, the plurality of protrusions 21 are inserted into the plurality of grooves 101, which can lock the connecting rod 2 on the inner side of the top surface of the lid 100, thereby improving the stability of the lid locking structure.
[0048] In this embodiment, four protrusions 21 are evenly provided circumferentially on the upper end surface of the connecting rod 2, which has a simple structure and a stable fit.
[0049] In another embodiment, such as Figure 1-7 As shown, the present invention provides a kettle lid, which includes a kettle lid locking structure as described in any of the above embodiments.
[0050] The kettle lid 100 includes a lid top cover 103 and a lid bottom cover 104. The lid top cover 103 and the lid bottom cover 104 are sealed together to form a cavity. The lid lock structure is located in the cavity. The lid top cover 103 is provided with a mounting hole for installing the lid opening knob 1. The side wall of the lid bottom cover 104 is provided with an opening for the locking tongue 40 to extend.
[0051] Furthermore, a sealing ring 102 may be provided between the upper lid 103 and the lower lid 104. The inner side of the sealing ring 103 is located between the upper lid 103 and the lower lid 104 to provide a sealing connection, and the outer side is in close contact with the mouth of the pot to provide a sealing function between the mouth of the pot and the lid 100.
