DETAILED DESCRIPTION

[0043] The application will now be described further to with reference to the drawings. These drawings show only the essential parts of the application and are not to scale as they are intended for use in illustration of the application. Hence, they show only those parts of the application that are relevant for an understanding of the application.

[0044] Electric pressure cooker, please refer to Figures 1-3 As shown, it comprises: pot body 100, pot cover 200 and supporting cantileaver 300.

[0045] The pot body 100 can be provided with an inner container which can be fixed to the pot body 100 or can be taken out of the pot body 100. The pot cover 200 is arranged on the top of the pot body 100. The support cantilever 300 is arranged on the pot body 100, so that the pot cover 200 can be installed on the pot body 100 in a flip cover mode or can be completely removed from the pot body 100 for convenient cleaning.

[0046] Specifically, as shown in Figure 1 and Figure 4 , the support cantilever 300 is generally in an L shape. One end of the support cantilever 300 is rotatably connected to the side surface of the pot body 100, and the other end is assembled with the pot cover 200.

[0047] The pot cover 200 is detachably assembled with the support cantilever 300. One of the pot cover 200 and the support cantilever 300 is provided with a recess, and the other is provided with a boss. One of the recess and the boss is provided with a limiting groove, and the other is provided with a protrusion which can be clamped into the limiting groove.

[0048] The support cantilever 300 is rotatably connected to the side surface of the pot body 100. The support cantilever 300 can be rotated to a first position and a second position.

[0049] When the support cantilever 300 is rotated to the first position, the pot cover 200 is arranged on the pot body 100. When the support cantilever 300 is rotated to the second position, the pot cover 200 is separated from the pot body 100.

[0050] Specifically, in one embodiment, a recess can be arranged at the center of the pot cover 200, and a boss can be arranged on the support cantilever 300.

[0051] Then, a limiting groove is arranged on the inner side wall of the recess, and a protrusion is arranged on the outer wall of the boss.

[0052] Alternatively, a protrusion is arranged on the inner side wall of the recess, and a limiting groove is arranged on the outer wall of the boss.

[0053] When assembled, the boss is aligned and clamped into the recess, and the protrusion is aligned and clamped into the limiting groove.

[0054] In another embodiment, a recess can be arranged at the center of the support cantilever 300, and a boss can be arranged on the pot cover 200.

[0055] Then, a limiting groove is arranged on the inner side wall of the recess, and a protrusion is arranged on the outer wall of the boss.

[0056] Alternatively, a protrusion is arranged on the inner side wall of the recess, and a limiting groove is arranged on the outer wall of the boss.

[0057] When assembled, the boss is aligned and clamped into the recess, and the protrusion is aligned and clamped into the limiting groove.

[0058] The two modes can complete the simple assembly between the pot cover 200 and the support cantilever 300 through the cooperation of the boss and the recess and the cooperation of the protrusion and the limiting groove.

[0059] As shown in Figure 4 , the support cantilever 300 is located at the first position, and the support cantilever 300 can be rotated clockwise with the first position as a reference to the second position. Figure 4 Figure 4 Further, the support cantilever 300 can be rotated clockwise by an angle of a, 0° < a < 180°.

[0060] Preferably, the support cantilever 300 can be rotated clockwise by an angle of 90°, and the support cantilever 300 drives the pot cover 200 to rotate to the vertical position, which is approximately as shown in

[0061] Preferably, the support cantilever 300 can be rotated clockwise by an angle of 135°, and the support cantilever 300 drives the pot cover 200 to rotate to the inclined position, which is approximately as shown in Figure 14 .

[0062] Preferably, the support cantilever 300 can be rotated clockwise by an angle of 135°, and the support cantilever 300 drives the pot cover 200 to rotate to the inclined position, which is approximately as shown in Figure 13 .

[0063] Further, one end of the support cantilever 300 is connected to the back of the pot body 100, and a rotating shaft, a shaft hole or the like structure is arranged between the support cantilever 300 and the pot body 100, so that the support cantilever 300 can be pivoted and rotated.

[0064] Alternatively, one end of the support cantilever 300 is connected to the back of the pot body 100, and a rotating shaft, a shaft hole, a multi-stage gear disc or the like structure is arranged between the support cantilever 300 and the pot body 100, so that the support cantilever 300 can be rotated to different positions relative to the pot body 100, such as a second position of 90° or a third position of 135°.

[0065] In one embodiment, the pot cover 200 or the support cantilever 300 is provided with a lock catch assembly 400, which comprises a lock tongue 410 and a reset spring 430.

[0066] In this embodiment, the lock catch assembly 400 is arranged in the pot cover 200, as shown in Figures 5-6 , the lock catch assembly 400 comprises a lock tongue 410 and a reset spring 430, and the lock tongue 410 extends into the limiting groove under the elastic force of the reset spring 430 to prevent the protrusion from exiting the limiting groove.

[0067] ​When the pot cover 200 and the support cantilever 300 are assembled, the user pushes the protrusion into the limiting groove, the locking tongue 410 moves inward and leaves the limiting groove under the external force, and after the protrusion enters the limiting groove, the locking tongue 410 moves again and protrudes into the limiting groove under the elastic force of the reset spring 430, so that the protrusion cannot exit the limiting groove, that is, the pot cover 200 and the support cantilever 300 cannot be separated.

[0068] Further, the pot cover 200 defines a position for assembling the locking tongue 410 and the reset spring 430, specifically, the pot cover 200 can be provided with a protrusion or the like structure to define the position for assembling the locking tongue 410 and the reset spring 430;

[0069] In an embodiment, the lock catch assembly 400 further comprises a gravity pin 420.

[0070] The gravity pin 420 interferes with the locking tongue 410 when the support cantilever 300 is rotated to the first position, so that the locking tongue 410 cannot leave the limiting groove.

[0071] The gravity pin 420 is out of interference with the locking tongue 410 when the support cantilever 300 is rotated to the second position, and the locking tongue 410 leaves the limiting groove under the external force.

[0072] Further, the locking tongue 410 is provided with an embedded groove 411 with an opening facing upward, and the gravity pin 420 is located in a vertical position when the pot cover 200 is placed on the pot body 100, and the gravity pin 420 partially enters the embedded groove 411 under its own gravity.

[0073] As shown in Figure 6 , the pot cover 200 is placed horizontally, in this orientation, the gravity pin 420 is vertically installed, the locking tongue 410 is horizontally installed and moves horizontally, the reset spring 430 is horizontally installed and provides elastic force for the horizontal movement of the locking tongue 410, and the pot cover 200 defines a vertical channel for assembling the gravity pin 420.

[0074] The gravity pin 420 interferes with the locking tongue 410 when the support cantilever 300 is rotated to the first position, so that the locking tongue 410 cannot leave the connection between the pot cover 200 and the support cantilever 300; as shown in Figures 5-6 , after the pot cover 200 is installed on the support cantilever 300, and the support cantilever 300 is in the first position, the orientation of the locking tongue 410 is horizontal installation, and the gravity pin 420 is vertically installed; as shown in Figure 6 , the locking tongue 410 protrudes from the connection between the pot cover 200 and the support cantilever 300 under the elastic force of the reset spring 430, that is, Figure 6 , the locking tongue 410 protrudes to the left; Figure 6The middle and heavy gravity pin 420 has not been moved down, but the gravity pin 420 should be moved down under its own gravity, and partially inserted into the lock tongue 410 to form an interference with the lock tongue 410, so that the lock tongue 410 cannot move to the right and cannot leave the connection between the pot cover 200 and the supporting cantilever 300, so that the pot cover 200 and the supporting cantilever 300 cannot be separated;

[0075] The gravity pin 420 is out of interference with the lock tongue 410 when the supporting cantilever 300 is rotated to the second position, and the lock tongue 410 leaves the connection between the pot cover 200 and the supporting cantilever 300 under external force; specifically, as shown in Figure 13 When the pot cover 200 and the supporting cantilever 300 are rotated, the pot cover 200 is inclined to be arranged, and the rotation angle of the pot cover 200 is greater than 90°, at this time, the gravity of the gravity pin 420 does not point to the lock tongue 410, and the gravity pin 420 leaves the lock tongue 410 under its own gravity, that is, it no longer forms an interference with the lock tongue 410, and the lock tongue 410 can move inward to leave the connection between the pot cover 200 and the supporting cantilever 300, so that the pot cover 200 can be removed from the supporting cantilever 300.

[0076] More specifically, as shown in Figure 6 The lock tongue 410 is provided with an embedded groove 411 with an opening upward, and the gravity pin 420 is located in a vertical position when the pot cover 200 is arranged on the pot body 100, and the gravity pin 420 partially enters the embedded groove 411 under its own gravity.

[0077] In the above technology, when the pot cover 200 is arranged on the pot body 100, the gravity pin 420 is clamped in the lock tongue 410, which ensures that the pot cover 200 cannot leave the supporting cantilever 300.

[0078] Alternatively, when the supporting cantilever 300 can have multiple rotation positions, when rotated to a certain angle in the first rotation position, and the rotation angle is between 0°-90°, although the pot cover 200 can also be opened relative to the pot body 100, but at this angle, the gravity of the gravity pin 420 or part of the gravity still points to the lock tongue 410, so that the gravity pin 420 is still partially inserted into the embedded groove 411 of the lock tongue 410, at this time the pot cover 200 still cannot be removed from the supporting cantilever 300; when the supporting cantilever 300 is rotated between 90°-180°, after the pot cover 200 leaves the pot body 100, the gravity pin 420 leaves the embedded groove 411 of the lock tongue 410 under its own gravity, at this time the pot cover 200 can be removed from the supporting cantilever 300.

[0079] In one embodiment, as shown in Figures 7-10 In order to assemble the pot cover 200 and the supporting cantilever 300, a recess 210 is arranged on the upper surface of the pot cover 200, and the supporting cantilever 300 is correspondingly provided with a boss 310 clamped into the recess 210.

[0080] Specifically, the center of the pot cover 200 is provided with a recess 210, which is generally circular, and the boss 310 is also a circular table, which can be assembled with the support cantilever 300, and then the pot cover 200 and the pot body 100 are rotated and locked or unlocked, and the boss 310 can rotate in the recess 210. More specifically, as shown in Figure 2 and Figure 3 The pot cover 200 is provided with an upper pot tooth 260, and the pot body 100 is correspondingly provided with a lower pot tooth 110. When assembled, the upper pot tooth 260 and the lower pot tooth 110 are engaged when the pot cover 200 and the pot body 100 are rotated and locked, and the pot cover 200 will not be blown open by high-temperature steam when the inner container generates high temperature during cooking. When the pot cover 200 and the pot body 100 are rotated and unlocked, the upper pot tooth 260 and the lower pot tooth 110 are misaligned, so that the pot cover 200 can be separated from the pot body 100.

[0081] Further, as shown in Figures 7-10 The side of the recess 210 is provided with a limiting groove 211, and the side of the boss 310 is provided with a protrusion 311 which can be inserted into the limiting groove 211. The locking tongue 410 protrudes out of the limiting groove 211 under the elastic force of the reset spring 430, so that the protrusion 311 is limited in the limiting groove 211.

[0082] Specifically, as shown in Figure 8 The limiting groove 211 is L-shaped, and has a vertical segment 2111 and a horizontal segment 2112 connected to each other, and the locking tongue 210 protrudes into the vertical segment 2111.

[0083] As shown in Figure 10 The boss 310 is radially provided with a protrusion 311 on the side;

[0084] When assembled, the support cantilever 300 is in the second position, the recess 210 of the pot cover 200 is aligned with the boss 310 of the support cantilever 300, and then the pot cover 200 is pushed towards the support cantilever 300, and the boss 310 enters the recess 210. During this process, since the pot cover 200 is generally placed vertically at 90°, the gravity pin 420 moves away from the insertion groove 411 of the locking tongue 410, and under the reaction force of the boss 310, the locking tongue 410 moves towards the inside of the pot cover 200, avoiding the protrusion 311, and the protrusion 311 moves from the beginning to the end of the vertical segment 2111, and then the locking tongue 410 is again protruded out of the vertical segment 2111 under the elastic force of the reset spring 430, and the locking tongue 410 interferes with the protrusion 311, preventing the protrusion 311 from exiting the vertical segment 2111, and then preventing the pot cover 200 from being separated from the support cantilever 300.

[0085] When the support cantilever 300 rotates from the second position to the first position, the pot cover 200 is driven to rotate, and when the rotation is less than 90°, the gravity pin 420 moves to the embedding groove 411 of the locking tongue 410 under the action of gravity, and the gravity pin 420 is partially clamped in the embedding groove 411, so that the locking tongue 410 cannot be moved inward, that is, the protrusion 311 cannot move along the vertical section 2111 and away from the vertical section 2111, thereby preventing the pot cover 200 from being separated from the support cantilever 300.

[0086] When the support cantilever 100 is in the first position, the pot cover 200 is arranged behind the pot body 100, and the pot cover 200 needs to be rotationally locked with the pot body 100, so that the pot cover 200 rotates on the pot body 100 by a certain angle, so that the upper pot tooth 260 and the lower pot tooth 110 are engaged, and the assembly of the pot cover 200 and the pot body 100 is stable; during the rotation of the pot cover 200 on the pot body 100, the protrusion 311 rotates in the horizontal section 2112.

[0087] Similarly, during the unlocking process between the pot cover 200 and the pot body 100, the pot cover 200 is reversely rotated on the pot body 100, the protrusion 311 is reversely rotated in the horizontal section 2112, the upper pot tooth 260 and the lower pot tooth 110 are staggered, the support cantilever 300 is rotated to the second position, the gravity pin 420 is away from the embedding groove 411, the pot cover 200 is pulled, and the locking tongue 410 is moved inward to avoid the protrusion 311 under the action of the protrusion 311. The protrusion 311 moves to the beginning of the vertical section 2111 and away from the vertical section 2111, and the pot cover 200 is removed from the support cantilever 300.

[0088] In the present technology, as shown in Figure 11 , when the pot cover 200 is installed on the support cantilever 300, the upper pot tooth 260 of the pot cover 200 and the lower pot tooth 110 of the pot body 100 are staggered, and the support cantilever 300 can be directly rotated to arrange the pot cover 200 on the pot body 100, without the need for repositioning; as shown in Figure 12 , then the pot cover 200 is rotated by a certain angle, and the pot cover 200 and the pot body 100 are locked, which is simple and fast.

[0089] As shown in Figure 9 , the lock catch assembly 400 is provided with two symmetrical groups, and the protrusion 311 is also provided with two; alternatively, the number of the lock catch assembly 400 and the protrusion 311 can be changed accordingly.

[0090] In an embodiment, as shown in Figure 4 and Figure 10 , the support cantilever 300 is provided with a fan 320, the fan 320 is arranged close to or corresponding to the boss 310, and the surface of the support cantilever 300 is provided with an air inlet hole 301 and an air outlet hole 302 communicating with the fan 320;

[0091] AsFigure 10 As shown, the side of the support cantilever 300 and the end of the assembled pot cover 200 is provided with an air inlet hole 301, and the lower surface of the boss 310 is provided with an air outlet hole 302. When the fan 320 is running, the airflow enters from the air inlet hole 301 and is discharged from the air outlet hole 302.

[0092] As shown, the pot cover 200 is provided with an air inlet 201 and an air outlet 202. The air outlet hole 302 corresponds to the position of the air inlet 201. The air inlet 201 is located in the recess 210, and the air outlet 202 is located on the side of the pot cover 200. The airflow enters from the air inlet 201, flows inside the pot cover 200, and is discharged from the air outlet 202. Figure 7 Figure 9 As shown, the pot cover 200 is provided with an air inlet 201 and an air outlet 202. The air outlet hole 302 corresponds to the position of the air inlet 201. The air inlet 201 is located in the recess 210, and the air outlet 202 is located on the side of the pot cover 200. The airflow enters from the air inlet 201, flows inside the pot cover 200, and is discharged from the air outlet 202.

[0093] Further, the pot cover 200 includes an outer cover 220 and an inner cover 230, and a air duct is formed between the two, which connects the air inlet 201 and the air outlet 202.

[0094] After the pot cover 200 is installed on the support cantilever 300, when the fan 320 is running, the airflow enters from the air inlet hole 301, is discharged from the air outlet hole 302, enters the air duct of the pot cover 200 through the air inlet 201, and is finally discharged from the air outlet 202. This can quickly cool the pot cover 200, achieve rapid pressure reduction, and finally achieve the purpose of quickly opening the cover.

[0095] In one embodiment, the pot cover 200 is provided with a pressure relief port 203, the support cantilever 300 is provided with a sealing member 303, and after the pot cover 200 is assembled on the support cantilever 300, the sealing member 303 seals the pressure relief port 203. The pressure relief port 203 is located at the center of the recess 210, and the sealing member 303 is located at the center of the boss 310.

[0096] When the pot cover 200 is not assembled on the support cantilever 300 but is directly installed on the pot body 100, the pressure relief port 203 is in an open state, and the inner container is not pressurized, ensuring the safety of product use.

[0097] In one embodiment, the pot cover 200 is provided with a handle portion 270, an exhaust pipe 240, and a pressure limiting valve 250, and the exhaust pipe 240 communicates with the pot body 100.

[0098] The exhaust pipe 240 and the pressure limiting valve 250 are mainly used for pressure relief of the inner container to prevent the pressure in the inner container from being too large or to enable the pot cover to be quickly opened after pressure relief.

[0099] The handle portion 270 is mainly used for facilitating the separation of the pot cover 200 and the support cantilever 300 by applying force. The shape and structure of the handle portion 270 can not be limited.
