[0032] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0033] Figure 1 and Figure 2 A schematic structural diagram of a pot cover 300 in a locked state according to an embodiment of the present invention is shown; Figure 3 and Figure 4 A schematic structural diagram of a pot cover 300 in an unlocked state according to an embodiment of the present invention is shown.

[0034] like Figures 1 to 4 As shown, the pot cover 300 includes a cover body 100 and a support member 200. The support member 200 is located above the cover body 100 and is detachably mounted on the top surface of the cover body 100. The cover body 100 can rotate relative to the support member 200. In actual application, both ends of the support member 200 are fixedly connected to the pot body. By operating the cover body 100 to rotate relative to the pot body and the support member 200, the cover body 100 is opened or locked relative to the pot body.

[0035] like Figure 2 and Figure 4 As shown, the center of the cover 100 is provided with a central column 150, and the cover 100 is also provided with a connecting column 130 in an area away from the central column 150. The center of the support 200 is provided with a slot 250, and correspondingly, the support 200 is provided with a connecting hole 230 that matches the connecting column 130 in an area away from the slot 250, as shown in FIG. Figure 1 As shown, the connecting hole 230 is in an arc shape, so that the connecting column 130 can rotate and slide relatively in the connecting hole 230. The support member 200 is rotatably mounted on the central column 150 and the connecting column 130 through the slot 250 and the connecting hole 230, respectively. Specifically, when the cover 100 is rotated, the support member 200 can rotate relative to the central column 150 through the slot 250, and then rotate relative to the center of the cover 100. At the same time, the connecting column 130 on the cover 100 also rotates relative to the center of the support member 200. Since the connecting hole 230 is in an arc shape, the connecting column 130 can slide relatively in the connecting hole 230. In addition, the support member 200 can also rotate relative to the connecting column 130 through the connecting hole 230, thereby rotating eccentrically relative to the cover 100.

[0036] Furthermore, if Figure 2 and Figure 4As shown, the pot cover 300 further includes a rotating operating member 260, which includes a rotating column 265, which is rotatably installed in the slot 250, and the slot 250 and the rotating column 265 are both sleeved on the central column 150, so that the central column 150 is also located in the rotating column 265. Figure 6 As shown, a notch 261 is provided at the lower end of the side wall of the rotating column 265. Specifically, an annular fixed wall 268 is provided at the lower end of the rotating column 265. The notch 261 is arranged on the annular fixed wall 268. It can be understood that the notch 261 and the annular fixed wall 268 are in a corresponding relationship and are relatively positioned.

[0037] Among them, Figure 2 , Figure 7 and Figure 8 As shown, by rotating the rotating operating member 260, the rotating column 265 is rotated relative to the slot 250, and can be rotated until the annular fixed wall 268 is connected to the inner wall of the slot 250 to form a closed ring, that is, the gap 261 is blocked by the inner wall of the slot 250, so that the center column 150 can be locked through the closed ring. At this time, the support member 200 can only rotate relative to the center column 150 (that is, rotate relative to the center of the cover body 100) and cannot be separated from the center column 150, so that the support member 200 cannot be removed from the cover body 100, that is, the support member 200 and the cover body 100 are in a locked state.

[0038] In addition, if Figure 4 and Fig. 9 As shown, by rotating the rotating operating member 260, the rotating column 265 is rotated relative to the slot 250, and the notch 261 on the rotating column 265 is rotated to a specified position. At this time, the notch 261 is no longer blocked by the inner wall of the slot 250, and the center column 150 is no longer locked by the closed ring. When the support member 200 is rotated, the support member 200 no longer rotates relative to the center column 150, but rotates eccentrically relative to the connecting column 130 at the eccentric position on the cover body 100. The center column 150 also rotates relative to the connecting column 130 and deviates relative to the slot 250, and the center column 150 can move outside the notch 261 and disengage from the slot 250. Fig.10 At this time, the support member 200 and the cover body 100 are in an unlocked state, and the support member 200 can be removed from the cover body 100 and separated from the cover body 100. It can be seen that by operating the rotating column 265 to the corresponding position, the support member 200 and the cover body 100 can be unlocked, so that the support member 200 can be easily removed for cleaning.

[0039] According to one embodiment, a slot 250 is provided in the support member 200. The slot 250 has a transverse gourd-shaped cross section, including a receiving slot portion with a larger radius and a limiting slot portion with a smaller radius, the central column 150 is located in the limiting slot portion, and the rotating column 265 is installed in the receiving slot portion.

[0040] Specifically, when the operating rotating column 265 is rotated, the notch 261 can rotate with the rotating column 265 to a position opposite to the above-mentioned limiting groove portion, that is, a position where the annular fixed wall 268 overlaps with the limiting groove portion, so that a closed loop cannot be formed to lock the central column 150. At this time, by rotating the cover body 100 to make the support member 200 rotate eccentrically relative to the connecting column 130, the central column 150 can move relatively to the outside of the notch 261 and escape from the slot 250. In addition, the notch 261 can also rotate with the rotating column 265 to a position overlapping with the above-mentioned limiting groove portion, that is, a position where the annular fixed wall 268 corresponds to the limiting groove portion, and the inner wall of the annular fixed wall 268 of the rotating column 265 and the inner wall of the above-mentioned limiting groove are connected together to form a closed loop, through which the central column 150 can be locked.

[0041] According to yet another embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a cavity is provided at the center of the support member 200, and a shaft seat 220 is fixedly installed in the cavity. The shaft seat 220 and the support member 200 are separate structures. Figure 5 2 shows a schematic diagram of the structure of the shaft seat 220, the shaft seat 220 is provided with a slot 250 and a limit slot 251, and the shaft seat 220 is also provided with a notch 252 that is connected to the slot 250 and the limit slot 251. Figures 6 to 9 As shown, the rotating column 265 is located in the slot 250. By rotating the rotating operating member 260, the rotating column 265 can rotate relative to the slot 250, and the notch 261 on the side wall of the rotating column 265 can rotate with the rotating column 265 to align with or stagger with the notch portion 252. When the notch 261 rotates to stagger with the notch portion 252, a closed loop locking center column 150 can be formed. Figure 7 and Figure 8 When the notch 261 is rotated to align with the notch portion 252, the central column 150 is no longer locked, so that the central column 150 can be relatively moved outside the notch 261, such as Fig. 9 and Fig.10 shown.

[0042] Specifically, the shaft seat 220 is a hollow cylindrical structure with one end open, which includes an open end at the upper end and a sealing end at the lower end. The sealing end extends inward and upward to form a fixed inner cylinder 258. The fixed inner cylinder 258 is provided with a through hole that passes through the sealing end of the shaft seat 220. The through hole is the limiting groove 251. The shape of the limiting groove 251 matches the shape of the center column 150, so that the center column 150 is clamped in the limiting groove 251. Figure 5As shown, the slot 250 is the space between the inner wall of the shaft seat 220 and the outer wall of the fixed inner tube 258. The notch 252 is opened at the lower end of the side wall of the shaft seat 220 and passes through the sealing end of the shaft seat 220 and the wall of the fixed inner tube 258 respectively.

[0043] like Figure 2 , Figure 4 and Figure 5 As shown, the height of the fixed inner cylinder 258 is less than the height of the shaft seat 220, and the fixed inner cylinder 258 is coaxially arranged with the inner wall of the shaft seat 220. The annular fixed wall 268 is rotatably installed between the outer wall of the fixed inner cylinder 258 and the inner wall of the shaft seat 220. Figure 5 As shown, the notch 252 is provided at the junction of the side wall and the bottom wall of the shaft seat 220, and the cross-section of the notch 252 is L-shaped, that is, a portion of the lower end of the side wall and the bottom wall of the shaft seat 220 are connected to the slot 250. The fixed inner cylinder 258 is formed by extending upward from the junction of the bottom wall of the shaft seat 220 and the notch 252, so that the fixed inner cylinder 258 is connected to the bottom of the notch 252.

[0044] Further, see Figure 2 , Figure 7 and Figure 8 By rotating the rotating operating member 260, the annular fixed wall 268 on the rotating column 265 rotates to a position opposite to the limiting groove portion 251 of the fixed inner cylinder 258, and the notch 261 rotates to stagger with the notch portion 252, Figure 2 The relative position of the middle rotating column 265 and the card slot 250, the annular fixed wall 268 on the rotating column 265 and the inner wall of the fixed inner cylinder 258 are connected together to form a closed loop, thereby locking the central column 150. At this time, the support member 200 can only rotate relative to the center of the central column 150 and the cover body 100, and cannot be separated from the central column 150. At this time, the support member 200 and the cover body 100 are in a locked state and cannot be separated from each other. Figure 4 , Fig. 9 and Fig.10 As shown, by rotating the rotating operating member 260, the annular fixed wall 268 on the rotating column 265 continues to rotate 180 degrees, and the annular fixed wall 268 rotates to be sleeved on the outer wall of the fixed inner cylinder 258, and the notch 261 rotates to align with the notch portion 252, and the notch 261 rotates to align with the notch portion 252. Figure 4 The relative position of the central rotating column 265 and the locking groove 250. At this time, the central column 150 is no longer locked by the closed ring. When the cover 100 is rotated, when the support member 200 rotates eccentrically relative to the cover 100 around the connecting column 130, the central column 150 also rotates relative to the connecting column 130 and can move relative to the locking groove 250 to the outside of the notch 261, so that the support member 200 can be removed from the cover 100 and separated from the cover 100, that is, the support member 200 and the cover 100 are unlocked.

[0045] Alternatively, if Figure 7 and Fig. 9 As shown, the cross section of the center column 150 is in an "I" shape, which includes a center column 155, and also includes a first stop block 151 and a second stop block 152 respectively fixed at the upper end and the lower end of the center column 155, and a step surface is formed between the center column 155 and the first stop block 151 and the second stop block 152. The center column 155 can be clamped in the limiting groove 251 and abut against the inner wall of the fixed inner cylinder 258.

[0046] Specifically, Figure 2 and Figure 4 As shown, the lower end surface of the first stopper 151 abuts against the upper end edge of the fixed inner cylinder 258, and the annular fixed wall 268 at the lower end of the rotating column 265 can rotatably abut against the side end surface of the first stopper 151. That is, when the rotating column 265 rotates, the annular fixed wall 268 at the lower end of the rotating column 265 can rotate with the rotating column 265 relative to the first stopper 151 and abut against different parts of the side end surface of the first stopper 151. In addition, as Figure 7 and Fig. 9 As shown, the bottom of the slot 250 is further provided with an arc-shaped baffle 255, which is the bottom wall of the sealing end of the shaft seat 220. The central column 155 is clamped in the limiting groove 251 of the slot, and the arc-shaped baffle 255 abuts against the side wall of the central column 155 and is located at the step surface of the second stop block 152, that is, the arc-shaped baffle 255 abuts against the side wall of the central column 155 and stops at the upper end edge of the second stop block 152.

[0047] In addition, in an embodiment according to the present invention, Figures 1 to 4 As shown, the cover body 100 is symmetrically provided with two limiting posts 110 relative to the center of the cover body 100, and the connecting post 130 is arranged in the area between the central post 150 and the limiting post 110. Correspondingly, the support member 200 is symmetrically provided with two arc grooves matching with the limiting posts 110 relative to the center of the support member 200, and the arc grooves include a first section of the guide groove 210 and a second section of the offset groove 215 smoothly connected to the guide groove 210 at the first end.

[0048] Among them, Figure 1 As shown, when the support member 200 and the cover body 100 are locked, when the support member 200 rotates relative to the center of the cover body 100, the limiting posts 110 on the cover body 100 will be driven to slide relative to the guide grooves 210, and the sliding tracks of the two limiting posts 110 in their corresponding guide grooves 210 are symmetrical relative to the center of the support member 200; Figure 3As shown, by rotating the rotating operating member 260 so that the center column 150 is not locked by the closed ring, when the support member 200 rotates eccentrically relative to the connecting column 130 of the cover body 100, the two limiting columns 110 will be driven to rotate relative to the connecting column 130 and deflect in the offset groove 215. It should be understood that due to the eccentric rotation, the offset tracks and distances of the two limiting columns 110 in their corresponding offset grooves 215 are not the same. Preferably, the symmetry centers of the two offset grooves 215 can be set to deviate from the center column 150, for example, the symmetry centers are set to be located at the position of the connecting column 130, so as to facilitate the displacement of the limiting columns 110 in the offset groove 215. Here, the cooperation of the guide groove 210 and the offset groove 215 with the limiting column 110 plays a guiding and auxiliary role for the central rotation and eccentric rotation of the support member 200 relative to the cover body 100, and assists the disassembly and separation of the support member 200 and the cover body 100. It should be noted that the width of the guide groove 210 is smaller than the cross-sectional width of the top of the limit column 110, so that it can be stopped at the top of the limit column 110, and the width of the offset groove 215 is larger than the cross-sectional width of the top of the limit column 110, so that it can be separated from the limit column 110 upward.

[0049] Specifically, Fig.11 and Fig.12 As shown, the limiting column 110 includes a column 111 and a truncated cone 112 located at the top of the column 111, a step surface is formed between the truncated cone 112 and the column 111, and one end of the column 111 away from the truncated cone 112 is fixedly connected to the cover 100, the width of the guide groove 210 is smaller than the diameter of the truncated cone 112, and the width of the offset groove 215 is larger than the diameter of the truncated cone 112. Figure 1 , Figure 3 and Fig.11 As shown, the guide groove 210 is in the shape of an arc strip, and the offset groove 215 is in the shape of an arc block. Therefore, when the support member 200 is locked with the cover body 100, that is, in the state of the closed ring lock center column 150, when the cover body 100 is rotated to make the limit column 110 slide relative to the guide groove 210, the column 111 of the limit column 110 is inserted into the guide groove 210 and is stopped on the top surface of the guide groove 210 by the round table 112, that is, the guide groove 210 is stopped below the round table 112, so that the guide groove 210 cannot be separated from the limit column 110 upwards; when the support member 200 is disassembled, the rotating operating member 260 is rotated to make the limit column 110 slide relative to the guide groove 210. The center column 150 is not locked by the closed ring. When the cover body 100 is rotated, the support member 200 rotates eccentrically relative to the cover body 100, and the limiting column 110 slides relative to the offset groove 215. When the eccentric rotation causes the center column 150 to move outside the notch 261, the slot 250 of the support member 200 is disengaged from the center column 150. Moreover, since the width of the offset groove 215 is greater than the width of the cone 112, the offset groove 215 can also be disengaged upward from the limiting column 110, so that the support member 200 can be taken away upward and separated from the cover body 100.

[0050] Further, Figure 1 The figure also shows the sliding track range of the limit column 110 and the connecting column 130 when the support member 200 rotates relative to the center of the cover body 100, and the rotation angle is along the rotation from yy to xx. When the support member 200 rotates eccentrically relative to the connecting column 130 of the cover body 100, the center column 150 deviates relative to the slot 250, and the limit column 110 deviates relative to the offset slot 215. The offset track is shown in FIG. Figure 3 As shown, the rotation angle is the rotation from xx to zz, and the offset tracks of the two limit posts 110 in their corresponding offset grooves 215 are not the same. Figure 3 It can also be seen in the figure that the limiting column 110 which is farther away from the central hole 230 has a longer offset track in the offset groove 215 .

[0051] Here, it should be understood that the rotation angle and sliding trajectory of the limiting column 110 and the connecting column 130 can be adjusted by the gear assembly, and the rotation angles of the two can be set to be the same or different, which will not be listed here one by one.

[0052] In an embodiment according to the present invention, Figure 2 , Figure 4 and Figure 6 As shown, the rotating operating member 260 includes a rotating column 265 and an operating portion 266 located at the upper end of the rotating column 265. The support member 200 includes a fixed portion 280 located at the lower end and a top cover 290 snap-connected to the top surface of the fixed portion 280, and a accommodating space is formed between the top cover 290 and the fixed portion 280. A through hole is provided on the top cover 290 to facilitate the exposure of the operating portion 266. The operating portion 266 protrudes from the outside of the support member 200 through the through hole of the top cover 290, so that the rotating operating member 260 is pressed or rotated by rotating the operating portion 266. In addition, a baffle 267 is fixedly connected between the rotating column 265 and the operating portion 266. The baffle 267 is formed by protruding from the lower end of the operating portion 266, and the width of the baffle 267 is greater than the width of the rotating column 265, thereby forming a step surface between the baffle 267 and the rotating column 265. As shown Figure 2 and Figure 4 As shown, the rotating column 265 is accommodated in the slot 250, the operating portion 266 protrudes outside the support member 200 for easy operation, and the baffle 267 can be stopped at the bottom surface of the top cover 290 to limit the rotating operating member 260 from escaping upward from the support member 200.

[0053] Furthermore, if Figure 6 As shown, two plug-in posts 269 are symmetrically provided at both ends of the baffle 267, and the plug-in posts 269 can be plugged into the sockets (not marked in the figure) of the upper cover 290 and snap-connected therewith. By pressing the rotating operating member 260, the plug-in posts 269 are disengaged from the sockets, so that the rotating operating member 260 can be selected. Figure 2 and Figure 4As shown, the top surfaces of the baffle 267 and the shaft seat 220 are both located in the accommodation space between the top cover 290 and the fixing part 280, and there is a space of a certain height between the baffle 267 and the top surfaces of the shaft seat 220. The rotating operating member 260 can be sleeved with an elastic member, which can be a spring 240, and the spring 240 abuts between the top surfaces of the baffle 267 and the shaft seat 220. Thus, when the rotating operating member 260 is pressed, the extrusion spring 240 is compressed downward, and the plug-in column 269 is disengaged from the socket so that the rotating operating member 260 can be rotated; when the rotating operating member 260 is rotated 180° and released, the rotating operating member 260 can be restored to its original position by the elastic restoring force of the spring 240, so that the plug-in column 269 is clamped in the socket again. With the above arrangement, the rotating operating member 260 can only be rotated when pressed, avoiding the accidental unlocking of the support member 200 from the cover body 100 due to misoperation.

[0054] In addition, if Figure 1 and Figure 3 As shown, a mark 291 is also provided on the top surface of the top cover 290. The mark is used to show whether the cover body 100 and the support member 200 are currently in a locked state or an unlocked state.
