Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] As Figures 1 to 7 shown, an embodiment of the present utility model provides a cover assembly. The cover assembly includes an inner cover 20 and an anti-blocking cover 30. The inner cover 20 has a mounting hole 21 penetrating up and down. The inner cover 20 is provided with a downwardly extending flanging 22 at the mounting hole 21. The anti-blocking cover 30 is detachably connected to the flanging 22. When the cover assembly discharges gas through an exhaust pipe installed at the mounting hole 21, the anti-blocking cover 30 can be used to prevent food in the cooking appliance from contaminating and blocking the exhaust pipe.

[0033] Applying the cover assembly provided in this embodiment, the cover assembly includes an inner cover 20 and a clogging prevention cover 30. By arranging the clogging prevention cover 30 at the flanging 22, compared with the related art where the clogging prevention cover and the inner cover are connected by a connecting member, in this embodiment, by providing a flanging 22 at the mounting hole 21 and detachably connecting the clogging prevention cover 30 to the flanging 22, it is convenient to install the clogging prevention cover 30, the connecting member is omitted, and the installation structure of the clogging prevention cover is simplified.

[0034] It should be noted that the flanging 22 and the inner cover 20 are of an integrally formed structure.

[0035] As Figure 3 and Figure 7 shown, the upper end of the clogging prevention cover 30 has an opening 31. The clogging prevention cover 30 is sleeved on the outside of the flanging 22 through the opening 31, and the clogging prevention cover 30 is snap-connected to the flanging 22. Since the clogging prevention cover 30 is sleeved on the outside of the flanging 22 through the opening 31 and the clogging prevention cover 30 is snap-connected to the flanging 22, the detachable connection structure between the clogging prevention cover 30 and the flanging 22 is simple and easy to operate.

[0036] As Figures 5 to 7 shown, the clogging prevention cover 30 includes an inner side wall and a first snap connection platform 32 provided on the inner side wall. The flanging 22 includes an outer side wall and a second snap connection platform 221 provided on the outer side wall. The first snap connection platform 32 is snap-connected to the second snap connection platform 221. By utilizing the snap connection between the first snap connection platform 32 and the second snap connection platform 221, the disassembly and assembly operation of the clogging prevention cover 30 relative to the flanging 22 is fast and reliable.

[0037] As Figure 5 and Figure 6 shown, the radial dimension of the second snap connection platform 221 is L1, the height difference between the lower surface of the counterbore 23 and the upper end of the second snap connection platform 221 is L2, the radial dimension of the first snap connection platform 32 is L3, and the height difference between the lower end of the first snap connection platform 32 and the upper end of the clogging prevention cover 30 is L4, where L1 > L3 and L2 > L4.

[0038] As Figure 6 and Figure 7 shown, the first snap connection platform 32 is a convex bulge provided on the inner side wall of the clogging prevention cover 30. The first snap connection platform 32 can be integrally formed with the clogging prevention cover 30, making the first snap connection platform 32 easy to process and form.

[0039] As Figure 6 and Figure 7 shown, the convex bulge is an annular structure extending along the circumferential direction of the clogging prevention cover 30. By adopting the annular convex bulge structure, the reliability of the snap connection between the first snap connection platform 32 and the second snap connection platform 221 in the circumferential direction of the clogging prevention cover 30 can be improved.

[0040] It should be noted that the convex bulge may also include a plurality of dot-like structures distributed along the circumferential direction of the clogging prevention cover 30.

[0041] As shown Figure 5 in FIG. 1, the flanging 22 includes a connecting cylinder section 222 and an upwardly turned cylinder section 223 disposed around the outer side of the connecting cylinder section 222. The upper end of the connecting cylinder section 222 is connected to the inner lid 20, the lower end of the connecting cylinder section 222 is connected to the lower end of the upwardly turned cylinder section 223, the upper end of the upwardly turned cylinder section 223 is spaced from the lower surface of the inner lid 20, and the upwardly turned cylinder section 223 forms a second snap connection platform 221. With the flanging having the above structure, since the lower end of the connecting cylinder section 222 is connected to the lower end of the upwardly turned cylinder section 223, during the process of installing the anti-blocking cover 30 onto the flanging 22, it is possible to avoid the lower ends of the connecting cylinder section 222 and the upwardly turned cylinder section 223 from damaging the anti-blocking cover 30, and it is easy to process and form.

[0042] Among them, the connection between the connecting cylinder section 222 and the upwardly turned cylinder section 223 is elastic. Thus, during the process of installing the anti-blocking cover 30 onto the flanging 22, the upwardly turned cylinder section 223 is deformed inwardly under the action of the inner side wall of the anti-blocking cover 30, reducing the installation resistance of the anti-blocking cover 30.

[0043] As shown Figure 5 in FIG. 2, the connecting cylinder section 222 and / or the upwardly turned cylinder section 223 is a tapered cylinder that gradually contracts in the upward-to-downward direction. During the process of installing the anti-blocking cover 30 onto the flanging 22, with the above structure, it is convenient to align the upper end of the anti-blocking cover 30 with the flanging 22, and it is convenient to cover the anti-blocking cover 30 on the flanging 22, facilitating installation.

[0044] In this embodiment, both the connecting cylinder section 222 and the upwardly turned cylinder section 223 are tapered cylinders that gradually contract in the upward-to-downward direction.

[0045] As shown Figure 6 and Figure 7 in FIGS. 3 and 4, the anti-blocking cover 30 is provided with a break groove 33 extending along its axial direction, and the upper end of the break groove 33 extends to the opening 31. During the process of installing the anti-blocking cover 30 onto the flanging 22, it makes the opening 31 of the anti-blocking cover 30 easy to deform, align the opening 31 with the flanging 22, make the opening 31 sleeved on the outer side of the flanging 22, and push the anti-blocking cover 30 in the direction close to the inner lid 20, making the opening 31 expand and deform outwardly, thereby snap-connecting the anti-blocking cover 30 and the flanging 22, reducing the installation resistance of the anti-blocking cover 30.

[0046] As shown Figure 6 and Figure 7 in FIGS. 5 and 6, the anti-blocking cover 30 is provided with a plurality of break grooves 33 arranged along its circumferential direction.

[0047] As shown Figure 6As shown, a flaring structure communicating with the opening 31 is provided on the anti-blocking cover 30. During the process of installing the anti-blocking cover 30 onto the flanging 22, the flaring structure is adopted, which facilitates aligning the opening 31 with the flanging 22 and covering the anti-blocking cover 30 on the anti-blocking cover 30, thus facilitating the installation.

[0048] As Figures 1 to 3 shown, the cover assembly further includes an exhaust pipe sealing ring 40, which is inserted through the flanging and is snap-connected to the flanging. By providing the exhaust pipe sealing ring 40, the airtightness at the installation hole 21 can be improved, and the exhaust pipe sealing ring 40 is snap-connected to the flanging, making the exhaust pipe sealing ring 40 easy to assemble.

[0049] As Figure 1 and Figure 5 shown, the outer wall of the exhaust pipe sealing ring 40 has a third snap-connecting platform 41 and a fourth snap-connecting platform 42 arranged at intervals along its axial direction. The upper surface of the inner cover 20 has a sunken platform 23, and the inner hole of the sunken platform 23 forms the installation hole 21. The third snap-connecting platform 41 is snap-connected to the upper surface of the sunken platform 23, and the fourth snap-connecting platform 42 is snap-connected to the lower end of the flanging 22. With the above structure, by using the third snap-connecting platform 41 to be snap-connected to the upper surface of the sunken platform 23 and the fourth snap-connecting platform 42 to be snap-connected to the lower end of the flanging 22, the exhaust pipe sealing ring 40 can be quickly and stably installed in the installation hole 21. Moreover, by providing the sunken platform 23 on the upper surface of the inner cover 20 and the inner hole of the sunken platform 23 forming the installation hole 21, the size of the exhaust pipe sealing ring 40 in the up and down direction can be reduced, which is beneficial to improving the structural compactness of the cover assembly.

[0050] It should be noted that the structure of this embodiment can also be applied to the cover assembly of the caliper structure.

[0051] Another embodiment of the present utility model provides a cooking appliance, which includes a pot body and a cover assembly. The cover assembly is openably and closably covered on the pot body. The cover assembly further includes a face cover, a lining, and an exhaust pipe. The lining is arranged below the face cover, the inner cover 20 of the cover assembly is arranged below the lining, the exhaust pipe passes through the lining, the lower end of the exhaust pipe passes out of the installation hole 21 of the cover assembly, and the inner cover 20 is provided with a cover tooth 24. The cover assembly is the cover assembly provided above. When the cover assembly exhausts through the exhaust pipe installed at the installation hole 21 in the cooking appliance of this embodiment, the anti-blocking cover 30 can be used to prevent the food in the cooking appliance from contaminating and blocking the exhaust pipe. By arranging the anti-blocking cover 30 on the flanging 22, compared with the related art in which the anti-blocking cover and the inner cover are connected by a connecting piece, in this embodiment, by providing the flanging 22 at the installation hole 21 and detachably connecting the anti-blocking cover 30 to the flanging 22, it is convenient to install the anti-blocking cover 30, the connecting piece is omitted, and the installation structure of the anti-blocking cover is simplified.

[0052] Among them, when the cover body assembly is covered on the pot body and the inner cover 20 is rotated relative to the outer cover, the cover teeth 24 can be engaged with or separated from the pot teeth of the pot body. The face cover can be used to shield the inner liner and the components provided on the inner liner.

[0053] In this embodiment, a chute is provided on the inner side wall of the outer cover, and a plug block slidably engaged with the chute is provided on the outer side wall of the inner cover 20. The dimension of the chute along the circumferential direction of the outer cover is larger than the dimension of the plug block along the circumferential direction of the outer cover, and the width of the chute is larger than the dimension of the plug block along the width direction of the chute. A cover tooth that is engaged with the pot teeth of the pot body of the cooking appliance is provided at the lower edge of the inner cover 20. When installing the inner cover 20, the inner cover 20 that is inclined relative to the outer cover is used to insert the plug block into the chute, and then the inner cover 20 is pushed, so that with the plug block as the swing point, the inner cover 20 swings towards the direction close to the outer cover, thereby installing the inner cover 20 on the outer cover. When disassembling the inner cover 20, the inner cover 20 is pulled, so that with the plug block as the swing point, the inner cover 20 swings towards the direction away from the outer cover, and the inner cover 20 is inclined relative to the outer cover to facilitate taking out the plug block from the chute.

[0054] Among them, when the inner cover 20 is installed on the outer cover and the cover body assembly is covered on the pot body, since the dimension of the chute along the circumferential direction of the outer cover is larger than the dimension of the plug block along the circumferential direction of the outer cover, the inner cover 20 can be rotated relative to the outer cover, and the plug block slides in the chute along the rotation direction, so that the cover teeth are engaged with or separated from the pot teeth of the pot body. During the cooking process, since the width of the chute is larger than the dimension of the plug block along the width direction of the chute, with the change of the pressure inside the cooking appliance, the inner cover 20 floats towards the direction close to or away from the outer cover relative to the pot body, and the plug block slides in the chute along the floating direction.

[0055] In this embodiment, a guide groove is further provided on the inner side wall of the outer cover, and a clamping block that is guidingly engaged with the guide groove is provided on the outer side wall of the inner cover 20. When installing the inner cover 20, the inner cover 20 that is inclined relative to the outer cover is used to insert the plug block into the chute, and then the inner cover 20 is pushed, so that with the plug block as the swing point, the inner cover 20 swings towards the direction close to the outer cover, and the clamping block extends into the guide groove, thereby installing the inner cover 20 on the outer cover. When disassembling the inner cover 20, the inner cover 20 is pulled, so that with the plug block as the swing point, the inner cover 20 swings towards the direction away from the outer cover, and the clamping block disengages from the guide groove, and the inner cover 20 is inclined relative to the outer cover to facilitate taking out the plug block from the chute.

[0056] In this embodiment, the dimension of the guide groove along the circumferential direction of the outer cover is larger than the dimension of the clamping block along the circumferential direction of the outer cover. When the inner cover 20 is rotated relative to the outer cover, the clamping block slides in the guide groove along the rotation direction. The width of the guide groove is larger than the dimension of the clamping block along the width direction of the guide groove. During the floating process of the inner cover 20, the clamping block slides in the guide groove along the floating direction.

[0057] In this embodiment, the cover assembly further includes a support member movably disposed on the outer cover. The support member has a second avoidance position for avoiding the clamping block from entering the guide groove and a support position for supporting the clamping block to keep the clamping block in the guide groove. When the support member is in the second avoidance position, the inner cover can be detached from the outer cover. When the support member is in the support position, the inner cover 20 is installed on the outer cover. When installing the inner cover 20, the inner cover 20 is inclined relative to the outer cover to insert the insertion block into the sliding groove, and then the inner cover 20 is pushed. Thus, with the insertion block as the swing point, the inner cover 20 swings towards the direction close to the outer cover, so that the clamping block presses the support member, the support member switches to the avoidance position, the clamping block extends into the guide groove, and the support member switches to the support position, thereby installing the inner cover 20 on the outer cover. When detaching the inner cover 20, the support member is switched to the avoidance position, and the inner cover 20 is pulled. Thus, with the insertion block as the swing point, the inner cover 20 swings towards the direction away from the outer cover, so that the clamping block disengages from the guide groove, and the inner cover 20 is inclined relative to the outer cover to facilitate removing the insertion block from the sliding groove.

[0058] In this embodiment, a notch communicating with the guide groove is provided on the outer cover, the support member is disposed in the notch, and the clamping block can enter and exit the guide groove through the notch.

[0059] In the related art, a pivot is provided at the central position of the outer cover, and the inner cover is connected to the pivot by means of a nut to make the pivot and the inner cover be movably connected.

[0060] In this embodiment, the installation hole only avoids the exhaust pipe. Since the pivot in the related art is not provided on the outer cover, the installation hole does not need to be set as a pivot hole for cooperating with the pivot, reducing components and costs. Moreover, the exhaust pipe provided on the outer cover will not interfere with the pivot in the related art, and the original set position of the exhaust pipe does not need to be adjusted on the outer cover, ensuring the original layout design on the outer cover. That is, on the premise that only minimal modifications are made to the cover assembly of the present application, the exhaust pipe can be retained at the original position. In this way, during the mold processing of the outer cover and the inner cover 20, the mold does not need to be greatly adjusted, which can reduce the design cost and improve the processing efficiency.

[0061] Specifically, the exhaust pipe sealing ring 40 is used to seal the gap between the installation hole 21 and the exhaust pipe, and the anti-blocking cover 30 is used to block food to prevent the exhaust pipe from being blocked.

[0062] In this embodiment, a pressure limiting valve that can be opened and closed is provided on the exhaust pipe.

[0063] It should be noted that the cooking appliance can be an electric pressure cooker or other cooking appliances with a pressure cooking function.
