[0001] The present application relates to the technical field of cookware, in particular to a pushing mechanism and a cover assembly and cookware comprising the same. BACKGROUND

[0002] Some cookware on the market are designed with double-layer covers to increase heat preservation and heat accumulation. Such cookware often have two opening and closing keys for controlling the two covers respectively. When a user first contacts such products, he or she cannot accurately identify which cover a certain opening and closing key corresponds to, which is likely to cause misoperation and cannot guarantee that the upper and lower covers are opened in sequence, thereby affecting use. SUMMARY

[0003] The present application aims to overcome the defect that the cookware with double-layer covers in the prior art cannot guarantee that the upper and lower covers are opened in sequence, and provides a pushing mechanism and a cover assembly and cookware comprising the same.

[0004] The present application solves the above technical problems by the following technical scheme:

[0005] A pushing mechanism, comprising a slider and a push rod, the slider being slidable in the movement direction of the push rod and provided with a first abutting surface, the push rod being provided with a second abutting surface, the slider having a locked state and an unlocked state, and the first abutting surface and the second abutting surface being in abutment in the movement direction of the push rod when the slider is in the unlocked state.

[0006] In the present application, in the locked state, the first abutting surface of the slider and the second abutting surface of the push rod are arranged in a staggered manner, and the slider does not abut against the push rod in the movement direction of the push rod, so that the slider is in a stationary state when the push rod moves. When the slider is in the unlocked state, the first abutting surface of the slider and the second abutting surface of the push rod are arranged in a facing manner. When the push rod is pushed, the second abutting surface contacts the first abutting surface and exerts a force in the movement direction of the push rod, so that the slider is displaced under the action of the push rod. It should be understood that the slider can be switched between the locked state and the unlocked state by electronic components or mechanical structures.

[0007] Preferably, the slider can move in a direction perpendicular to the movement direction of the push rod to switch between the locked state and the unlocked state.

[0008] In the present application, a sliding rail or guide rod can be arranged on the slider to switch between the locked state and the unlocked state by moving in a direction perpendicular to the movement direction of the push rod. Compared with other modes such as rotation, such a structure is simpler, more stable and reliable.

[0009] Preferably, the sliding block is provided with a through hole, the push rod passes through the through hole, and the sliding block can move along a direction perpendicular to the movement direction of the push rod through the through hole.

[0010] The through hole is arranged on the sliding block, and the push rod passes through the sliding block, so that the push mechanism is more compact in structure and can save the occupied space. The sliding block can move along a direction perpendicular to the movement direction of the push rod through the through hole, and such a structure can facilitate the switching between the locking state and the unlocking state of the sliding block without being hindered by the push rod.

[0011] Preferably, the first abutting surface is arranged outside the through hole.

[0012] In this structure, compared with arranging a protrusion on the sliding block or other parts of the sliding block to form the first abutting surface, the structure is simple and the processing cost is low.

[0013] Preferably, the sliding block comprises a first sliding block and a second sliding block, the first sliding block can move in a direction perpendicular to the movement direction of the push rod, the second sliding block is movably arranged on the first sliding block and can slide in the movement direction of the push rod, and the first abutting surface is arranged on the second sliding block.

[0014] In this scheme, the sliding block is divided into two parts, the first sliding block serves as the base of the second sliding block and is responsible for the movement in the vertical direction, and drives the second sliding block to move up and down. The first abutting surface is arranged on the second sliding block, and when the second sliding block moves to the unlocking state along with the first sliding block, the first abutting surface of the second sliding block abuts against the second abutting surface of the push rod, and the second sliding block is displaced under the action of the push rod.

[0015] Preferably, the first sliding block is provided with a first elastic member, the first elastic member abuts against and acts on the first sliding block to make the first sliding block tend to the unlocking state.

[0016] In this scheme, the first sliding block can maintain the unlocking state under the action of the first elastic member unless there is an external force.

[0017] Preferably, the first sliding block comprises a guide rod and a second elastic member, the guide rod is parallel to the movement direction of the push rod, the second sliding block is movably arranged on the guide rod, and the second elastic member acts on the second sliding block to abut against the first sliding block.

[0018] In this scheme, the second sliding block can automatically reset to abut against the first sliding block under the action of the second elastic member when the force of the push rod disappears.

[0019] A cover assembly comprises:

[0020] An upper cover, comprising a first lock catch and a limiting part, the limiting part being arranged at an opening and closing end of the upper cover;

[0021] A lower cover, comprising a pushing mechanism as described above, a second lock catch and a third lock catch, the second lock catch and the third lock catch being arranged rotatably on the lower cover, the push rod abutting against the second lock catch, and the sliding block abutting against the third lock catch.

[0024] In this solution, the push rod is pushed to apply a force to the distal end of the second lock catch, so that the second lock catch rotates, the locked state of the second lock catch and the first lock catch is destroyed, and the upper cover is opened relative to the lower cover. At this time, the limiting part of the upper cover is away from the lower cover with the opening and closing end, the sliding block loses the action of the limiting part and turns into an unlocked state, the first abutting surface of the sliding block and the second abutting surface of the push rod are arranged opposite to each other, the push rod is pushed, the second abutting surface contacts the first abutting surface and applies a force consistent with the movement direction of the push rod, the sliding block is displaced under the action of the push rod, applies a force to the distal end of the third lock catch, so that the third lock catch rotates, the locked state of the third lock catch and the fourth lock catch is destroyed, and the lower cover is opened relative to the base.

[0064] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0065] Example 1

[0066] like Figure 1 , Figure 3 As shown, a pushing mechanism includes a slider 1 and a push rod 2. The slider 1 can slide in the direction of movement of the push rod 2 and is provided with a first abutting surface 14. The front part of the push rod 2 is composed of a thin cylinder and the rear part is composed of a thick cylinder. The protrusion of the thick cylinder relative to the thin cylinder forms a second abutting surface 21. The slider 1 can move in the vertical direction to switch between a locked state and an unlocked state. When the slider 1 is in the unlocked state, the first abutting surface 14 and the second abutting surface 21 abut against each other in the direction of movement of the push rod 2.

[0067] In the scheme, the above structure is adopted, in the locked state, the first abutting surface 14 of the sliding block 1 is arranged in a staggered manner with the second abutting surface 21 of the push rod 2, and the sliding block 1 does not abut with the push rod 2 in the movement direction of the push rod 2, and the sliding block 1 is in a static state when the push rod 2 moves. When the sliding block 1 is in the unlocked state, the first abutting surface 14 of the sliding block 1 is arranged towards the second abutting surface 21 of the push rod 2, and the push rod 2 is pushed with force, the second abutting surface 21 contacts the first abutting surface 14 and applies a force consistent with the movement direction of the push rod 2, and the sliding block 1 is displaced under the action of the push rod 2. By providing a sliding rail or guide rod 113 on the sliding block 1, the movement of the sliding block 1 in the up-down direction is realized to switch the locked state and the unlocked state, and the switching state is more simple, stable and reliable. Of course, in other embodiments, the sliding block 1 can also be switched between the locked state and the unlocked state by rotation, even electronic signals of electronic components and other ways. For example, when the push rod is pushed for the first time, an unlocking electrical signal can be generated at the same time, so that the sliding block is unlocked, and when the push rod is pushed for the second time, the unlocked sliding block is displaced under the action of the push rod.

[0068] As shown in Figure 1 , Figure 3 As a preferred embodiment, the sliding block 1 includes a first sliding block 11 and a second sliding block 12, the first sliding block 11 can move in a direction perpendicular to the movement direction of the push rod 2, and the second sliding block 12 is movably arranged on the first sliding block 11 and can slide in the movement direction of the push rod 2, the first sliding block 11 and the second sliding block 12 are provided with a through hole 13, the push rod 2 penetrates through the through hole 13, and the first sliding block 11 and the second sliding block 12 can move up and down along a direction perpendicular to the movement direction of the push rod 2 through the through hole 13.

[0069] In the scheme, the sliding block 1 is divided into two parts, the first sliding block 11 serves as the base of the second sliding block 12 and is responsible for the movement in the vertical direction, driving the second sliding block 12 to move up and down. The first abutting surface 14 is arranged on the second sliding block 12, and when the second sliding block 12 moves with the first sliding block 11 to reach the unlocked state, the first abutting surface 14 of the second sliding block 12 abuts towards the second abutting surface 21 of the push rod 2, and the second sliding block 12 is displaced under the action of the push rod 2. Of course, in other embodiments, the sliding block 1 can also be a whole, and the vertical and horizontal movements can be realized by the combination of the sliding rail and the guide rod 113. The through hole 13 is arranged on the first sliding block 11 and the second sliding block 12, and the push rod 2 penetrates through the first sliding block 11 and the second sliding block 12, so that the top pushing mechanism is more compact in structure and can save the occupied space. The first sliding block 11 and the second sliding block 12 can move up and down along a direction perpendicular to the movement direction of the push rod 2 through the through hole 13, and such a structure can facilitate the switching between the locked state and the unlocked state of the sliding block 1.

[0070] As shown in Figure 2As shown, as a preferred embodiment, the through hole 13 of the second slider 12 is large at the top and small at the bottom, and the port of the smaller end of the through hole 13 at the bottom is the first abutting surface 14.

[0071] With this structure, compared with the structure in which a protrusion is arranged in the through hole 13 of the second slider 12 to form the first abutting surface 14, the structure is simple and the processing cost is low. Of course, in other embodiments, the through hole 13 of the second slider 12 can be of any irregular shape, so that part of the port of the through hole 13 forms the first abutting surface 14.

[0072] As shown in Figure 1 , Figure 3 As a preferred embodiment, the first slider 11 is provided with a first elastic member 111, which abuts against and acts on the first slider 11 to make the first slider 11 tend to be in the unlocked state.

[0073] In this scheme, under the action of an external force, the first elastic member 111 deforms, and the first slider 11 remains in the locked state; after the external force is removed, the first elastic member 111 returns to its original state and exerts a force on the first slider 11 to switch it to the unlocked state.

[0074] As shown in Figure 1 , Figure 2 As a preferred embodiment, the first slider 11 includes a guide rod 113 parallel to the movement direction of the push rod 2, and a second elastic member 112, and the second slider 12 is provided with a guide hole 121 and movably sleeved on the guide rod 113, and the second elastic member 112 acts on the second slider 12 to abut against the first slider 11.

[0075] In this scheme, under the action of the second elastic member 112, the second slider 12 can automatically reset to abut against the first slider 11 after the action force of the push rod 2 disappears.

[0076] As shown in Figure 3 , Figure 4 As shown in the embodiment, a cover assembly is provided, which includes an upper cover 3, a lower cover 4, and a base 5, wherein the upper cover 3 includes a first lock 31 and a limiting portion 32, and the limiting portion 32 is arranged at the opening and closing end of the upper cover 3; the lower cover 4 includes the push mechanism, a second lock 41, and a third lock 42, the second lock 41 and the third lock 42 are rotationally arranged on the lower cover 4, the slider 1 is provided with a boss 16 at the upper side, the lower cover 4 has a through hole 43 at the boss 16, the push rod 2 abuts against the second lock 41, and the slider 1 abuts against the third lock 42. The base 5 is provided with a fourth lock 51.

[0077] The latch of the first latch 31 engages with the latch of the second latch 41. The push rod 2 can act on the second latch 41 to unlock the second latch 41 from the first latch 31. The latch of the fourth latch 51 engages with the latch of the third latch 42. The slider 1 can act on the third latch 42 to unlock the third latch 42 from the fourth latch 51. The limiting part 32 and the slider 1 abut against each other through the through hole 43.

[0078] In this design, the middle parts of the second latch 41 and the third latch 42 are hinged relative to the lower cover 4. The second latch 41 is equipped with a torsion spring so that it rotates in the direction of engaging with the first latch. The third latch 42 is equipped with another torsion spring so that it rotates in the direction of engaging with the fourth latch. The push rod 2 is pushed to apply force to the end of the second latch 41 away from the first latch 31, causing the second latch 41 to rotate and breaking the fastening state between the second latch 41 and the first latch 31. The upper cover 3 opens relative to the lower cover 4. The push rod 2 is released, and the second latch 41 returns to its state before rotation under the action of the torsion spring so that the second latch 41 can engage with the first latch 31 when the upper cover 3 and the lower cover 4 close next time. At this time, as the opening and closing end moves away from the lower cover 4, the limiting part 32 of the upper cover 3 loses the function of the limiting part 32. The slider 1 moves under the action of the first elastic element 111, causing the slider 1 to switch to the unlocked state. The first abutting surface 14 of the slider 1 and the second abutting surface 21 of the push rod 2 are arranged facing each other. Pushing the push rod 2, the second abutting surface 21 contacts the first abutting surface 14 and applies a force in the same direction as the movement of the push rod 2. The slider 1 is displaced under the action of the push rod 2, and a force is applied to the end of the third latch 42 away from the fourth latch 51, causing the third latch 42 to rotate, breaking the fastening state of the third latch 42 and the fourth latch 51. The lower cover 4 opens relative to the base 5. The third latch 42 returns to the state before rotation under the action of the torsion spring after the push rod 2 is released, so that the third latch 42 and the fourth latch 51 can be fastened when the lower cover 4 and the base 5 are closed next time. The limiting part 32 abuts against the boss 16 of the slider 1 through the through hole 43. The limiting method is simple, easy to implement, and has low manufacturing cost.

[0079] like Figure 5 As shown, this embodiment also provides a cookware, including the lid assembly as described above.

[0080] With the above structure, the user can open the upper cover 3 and the lower cover 4 in sequence by pushing the push rod 2 with a single, repetitive operation.

[0081] Example 2

[0082] like Figure 6As shown, it is the embodiment 2 of the present application, the embodiment is basically same with embodiment 1, the difference is the structure of the upper cover 3 and the slider 1. Specifically, in the embodiment, the slider 1 is provided with the first magnetic member 15, and the limiting portion 32 of the upper cover 3 is the second magnetic member 33. In the scheme, the slider 1 is provided with the first magnetic member 15, and the limiting portion 32 of the upper cover 3 is composed of the second magnetic member 33, without opening the through hole 43 on the lower cover 4, the limiting portion 32 can rely on the repulsion between the magnetic members to exert force on the slider 1 to make the slider 1 in the locked state. When the upper cover 3 is opened relative to the lower cover 4, the second magnetic member 33 is away from the first magnetic member 15, the repulsion of the second magnetic member 33 to the first magnetic member 15 disappears, the slider 1 moves upward to switch to the unlocking state, and the first abutting surface 14 of the slider 1 is arranged opposite to the second abutting surface 21 of the push rod 2. Push the push rod 2 again, the second slider 12 is displaced under the action of the push rod 2, so that the third lock 42 is rotated, the locking state of the third lock 42 and the fourth lock 51 is destroyed, and the lower cover 4 is opened relative to the base 5. Such structure makes the sealing of the lower cover 4 better, which is conducive to ensuring the heat preservation and heat storage function of the cover assembly. Of course, in other embodiments, the limiting portion 32 can also attract the second magnetic member, at this time, the shape of the through hole of the second slider is changed to be large at the bottom and small at the top, which can also achieve the effect of making the slider 1 in the locked state.
