[0042] The present application provides a pet feeder 1, as shown in Figures 1-4 and Figure 9 The pet feeder 1 is used for a can 2, the can 2 includes a can body 21 and a cover 22 detachably connected to cover the can body 21, in an embodiment, the pet feeder 1 includes a material disc 11, a cover rotating device 12 and a lifting device 13, the material disc 11 is provided with a first limiting part 111, the first limiting part 111 is used for abutting against the can body 21 to limit the rotation of the can body 21; the cover rotating device 12 includes a first driving assembly 121 and a cover rotating assembly 122, the cover rotating assembly 122 includes a cover rotating piece 1221, the first driving assembly 121 is in transmission connection with the cover rotating piece 1221, the cover rotating piece 1221 is provided with a second limiting part 12213, the second limiting part 12213 is used for limiting cooperation with the cover 22 to drive the cover 22 to rotate; the lifting device 13 is in transmission connection with the first driving assembly 121, the lifting device 13 drives the cover rotating device 12 to move in the up-down direction, the cover rotating device 12 is used for driving the cover 22 to rotate relative to the can body 21.

[0043] ​When the pet has a feeding demand, the lifting device 13 drives the screw cap 1221 in the first driving assembly 121 to move towards the can 2, the second limiting part 12213 on the screw cap 1221 can be limited with the cover 22 of the can 2 on the material disc 11, the screw cap 1221 is driven to rotate by the first driving assembly 121, the first limiting part 111 on the material disc 11 can limit the rotation of the can body 21 relative to the material disc 11 to make the cover 22 and the can body 21 separate, so that the automatic opening of the cover of the can 2 is completed by the pet feeder 1 without the participation of personnel.

[0044] It should be noted that the first limiting part 111 can be a magnetic attraction piece, the first limiting part 111 can attract the can body 21 in contact with it, so as to limit the rotation of the can body 21 relative to the material disc 11; or the first limiting part 111 can be a lock, the first limiting part 111 is locked by the lock to limit the rotation of the can body 21 relative to the material disc 11.

[0045] It should be further pointed out that the cover 22 and the can body 21 are rotationally connected, the cover 22 rotates relative to the can body 21, so as to release the threaded connection, after the threaded connection is released, the cover 22 and the can body 21 are separated.

[0046] In the embodiment, the cover 22 and the can body 21 are in threaded connection; in other embodiments, the cover 22 and the can body 21 are in rotationally buckled connection.

[0047] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 The pet feeder 1 further comprises a second driving assembly 17, the second driving assembly 17 is in transmission connection with the material disc 11, and is used to drive the material disc 11 to rotate.

[0048] As shown in Figures 4-8As shown, in one embodiment, the first drive assembly 121 includes a first drive member 1211 and a first transmission member 1212 connected to each other. The capping member 1221 is slidably engaged with the first transmission member 1212. The capping member 1221 is movable in the vertical direction relative to the first transmission member 1212 and has a first position 12215 and a second position. In the first position 12215, the second limiting part 12213 is used to limit the engagement with the cover 22. In the second position, the second limiting part 12213 is used to disengage from the cover 22. In this embodiment, the lifting device 13 drives the capping member 1221, which is connected to the transmission of the first driving component 121, to move downward toward the can 2 so that the capping member 1221 contacts the lid 22. At this time, the second limiting part 12213 on the capping member 1221 may be in a limiting engagement with the lid 22 located on the material tray 11. Alternatively, the second limiting part 12213 on the capping member 1221 may not be in a limiting engagement with the lid 22 located on the material tray 11. In this case, when the first driving component 121 drives the capping member 1221 to rotate, the capping member 1221 slides with the first transmission component 1212, and the capping member 1221 moves downward and engages with the lid 22 located on the material tray 11.

[0049] Moreover, in the above technical solution, since the capping component 1221 and the first transmission component 1212 can slide and cooperate in the vertical direction, the first transmission component 1212 does not need to rise in coordination with the continuously rising position of the cover 22 as the capping component 1221 drives the cover 22 to rotate, because the capping component 1221 will slide upward relative to the first transmission component 1212 as the cover 22 rises.

[0050] like Figure 8 As shown, in one embodiment, the capping assembly 122 further includes a limiting member 1222, which is movably disposed on the first transmission member 1212. The limiting member 1222 is connected to the capping member 1221. When the capping member 1221 moves downward for a first stroke, the limiting member 1222 abuts against the first transmission member 1212. In this embodiment, by setting the limiting member 1222 to be connected to the capping member 1221, when the capping member 1221 moves downward relative to the first transmission member 1212 from the first position 12215 for a first stroke, the limiting member 1222 abuts against the transmission member, thereby limiting the capping member 1221 from continuing to descend and preventing the capping member 1221 from separating from the first transmission member 1212 due to gravity, which would lead to failure of the sliding fit.

[0051] And, as Figure 6 and Figure 8As shown, the screw cap assembly 122 further comprises a first reset member 1223, one end of the first reset member 1223 is connected with the screw cap member 1221, and the other end of the first reset member 1223 is connected with the first transmission member 1212, and the first reset member 1223 applies an elastic reset force to the screw cap member 1221 to move from the second position to the first position 12215. In the embodiment, the first reset member 1223 is arranged to drive the screw cap member 1221 to move to the first position 12215. If the second limiting portion 12213 fails to limit the cap body 22 when the lifting device 13 drives the first transmission member 1212 to descend the third stroke, the second limiting portion 12213 will be lifted by the cap body 22 and slide upward relative to the first transmission member 1212. At this time, the first driving member 1211 needs to drive the screw cap member 1221 to rotate by a preset angle. During the rotation of the screw cap member 1221, if the second limiting portion 12213 can limit the cap body 22 after descending at a certain position, the first reset member 1223 can quickly drive the screw cap member 1221 to move downward to make the second limiting portion 12213 limit the cap body 22 when the screw cap member 1221 rotates to the position. It should be noted that the first reset member 1223 can be a spring.

[0052] As shown in Figure 6 and Figure 7 The first transmission member 1212 is provided with a first installation channel 12121 penetrating upward and downward, the screw cap member 1221 comprises a screw cap body 12211 and a sliding portion 12212 connected with each other, the screw cap body 12211 is provided with a second limiting portion 12213, and the sliding portion 12212 is arranged in the first installation channel 12121 and in sliding cooperation with the first installation channel 12121. In the embodiment, the sliding portion 12212 is arranged in sliding cooperation with the first installation channel 12121, and the first installation channel 12121 can limit the movement of the screw cap body 12211 in the radial direction of the first installation channel 12121.

[0053] According to an embodiment of the present application, the number of the first installation channels 12121 is at least two, and the sliding portion 12212 is arranged in one-to-one correspondence with the number of the first installation channels 12121. By arranging at least two first installation channels 12121, the rotation of the screw cap body 12211 relative to the first transmission member 1212 is limited.

[0054] According to another embodiment of the present application, the first installation channel 12121 and the sliding portion 12212 are connected through a spline, so that the first installation channel 12121 can move relative to the sliding channel, and the spline connection can drive the screw cap body 12211 to rotate through the first transmission member 1212.

[0055] As shown in Figure 3 、 Figure 4 andFigure 6 As shown, in one embodiment, the first drive assembly 121 further includes a first bracket 1213, and the first drive member 1211 is mounted on the first bracket 1213. The lifting device 13 includes a second drive member 131 and a second transmission member 132 that are connected by transmission. The second transmission member 132 is provided with a lifting part 13211. The lifting part 13211 is in rolling cooperation with the first bracket 1213. The second drive member 131 drives the second transmission member 132 to move in the left and right directions, so that the lifting part 13211 can drive the first bracket 1213 to move in the up and down directions. In this embodiment, the second driving member 131 can drive the second transmission member 132 to move back and forth in the left and right direction. By providing the lifting part 13211, when the second driving member 131 drives the second transmission member 132 to move to the left, the lifting part 13211 can guide the first bracket 1213 to move upward; when the second driving member 131 drives the second transmission member 132 to move to the right, the lifting part 13211 can guide the first bracket 1213 to move downward, thereby converting the left and right movement of the second transmission member 132 into the up and down movement of the first bracket 1213 through the lifting part 13211.

[0056] In one embodiment, the second transmission member 132 includes a lifting body 1321 and a rack 1322 connected to each other. The lifting part 13211 is disposed on the lifting body 1321, and the output shaft of the second drive member 131 is provided with a gear 1311 for meshing with the rack 1322. In this embodiment, transmission is achieved through the meshing of the gear 1311 and the rack 1322, thereby effectively improving the transmission accuracy.

[0057] Those skilled in the art will readily conceive of using a lead screw assembly to achieve the reciprocating movement of the second transmission member 132. That is, the output shaft of the second drive member 131 is connected to the screw of the lead screw assembly, and the lifting part 13211 is connected to the slider of the lead screw assembly, which can also achieve the reciprocating movement of the second transmission member 132.

[0058] Furthermore, in one embodiment, the height of the lifting part 13211 is arranged to increase gradually along the extension direction of the rack 1322, so that the lifting movement of the first mounting frame can be more stable.

[0059] like Figure 4 As shown, the lifting part 13211 has a sliding groove 13212, and the first bracket 1213 is connected to a rolling element 12131. At least a portion of the rolling element 12131 extends into the sliding groove 13212 and rolls in engagement with the bottom wall of the sliding groove 13212. The rolling element 12131 can be a first rolling wheel. The rolling engagement between the first rolling wheel and the bottom wall of the sliding groove results in less friction compared to the sliding engagement between the first bracket 1213 and the sliding groove 13212.

[0060] likeFigure 3 , Figure 4 and Figure 6 As shown, in one embodiment, the pet feeder 1 includes a second bracket 14, a second drive member 131 mounted on the second bracket 14, and a second mounting channel 141 extending vertically through the second bracket 14. A first bracket 1213 is disposed in the second mounting channel 141 and slidably engages with the second mounting channel 141. A second transmission member 132 slidably engages with the second bracket 14 or rolls with the second bracket 14. In this embodiment, by providing the second mounting channel 141, the second mounting channel 141 can limit the movement of the first bracket 1213 relative to the second mounting channel 141 in the radial direction when it is slidably engaged with the first bracket 1213. The second transmission member 132 can either slidably engage with the second bracket 14 or roll with the second bracket 14. The frictional force experienced by the second transmission member 132 in the rolling engagement is smaller than that in the sliding engagement.

[0061] In one embodiment, the second support 14 is provided with a plurality of rollers 142, which are arranged sequentially along the moving direction of the second transmission member 132, and the rollers 142 roll in cooperation with the second transmission member 132. By providing a plurality of rollers 142, the reliability of the support provided by the rollers 142 to the second transmission member 132 is ensured.

[0062] like Figure 4 As shown, in one embodiment, the pet feeder 1 further includes a claw assembly 15, which is connected to the first drive assembly 121. The claw assembly 15 is used to grip or release the cover 22. In this embodiment, by providing the claw assembly 15, the cover 22, which is disengaged from the can body 21, can be gripped or released by the claw assembly 15.

[0063] In this embodiment, after the cover 22 is separated from the can 21, the claw assembly 15 holds the cover 22, and the lifting device 13 drives the cover 22 to rise through the claw assembly 15, so that the cover 22 can move away from the can 21.

[0064] Further, in an embodiment, the pawl assembly 15 is hinged with the first driving assembly 121, the pawl assembly 15 comprises a pawl 151 and a second reset member 152, the pawl 151 is used to detachably connect with the clamping portion 223 arranged on the cover 22, the pawl 151 is movable between a third position 1513 matched with the clamping portion 223 and a fourth position disengaged from the clamping portion 223, and the second reset member 152 applies an elastic reset force to the pawl 151 to move from the fourth position to the third position 1513. In this embodiment, the second reset member 152 is arranged to apply the elastic reset force to the pawl 151 to move to the third position 1513, so that the pawl 151 abuts against the clamping portion 223, thereby improving the reliability of the clamping cooperation between the pawl 151 and the clamping portion 223.

[0065] As shown in Figure 1 and Figure 10 In an embodiment, the pet feeder 1 further comprises a third support 16 arranged on the outer periphery of the pawl 151, and an inner wall of the third support 16 is provided with a first inclined surface 161 extending upwardly from the outside to the inside and towards the first driving assembly 121, and the pawl 151 cooperates with the first inclined surface 161 when the lifting device 13 moves upwardly to guide the pawl 151 from the third position 1513 to the fourth position. In this embodiment, when the lifting device 13 drives the transmission member to move upwardly, the pawl 151 abuts against the first inclined surface 161 and moves from the third position 1513 to the fourth position under the guidance of the first inclined surface 161, so that the cover 22 clamped by the pawl 151 is separated from the pawl 151; that is, the pawl assembly 15 clamps or releases the cover 22 without relying on the driving member driving the pawl 151 to reciprocate between the third position 1513 and the fourth position, so the cost is lower.

[0066] In an embodiment, when the lifting device 13 moves upwardly by a second stroke, the top of the pawl 151 abuts against the first inclined surface 161; that is, the lifting device 13 needs to move upwardly by the second stroke to ensure the separation of the cover 22 from the tank 21, and the top of the pawl 151 abuts against the first inclined surface 161 to avoid the interference between the movement of the tank 21 and the cover 22.

[0067] According to an embodiment of the present application, the number of the pawl assemblies 15 is at least two, and the at least two pawl assemblies 15 are arranged along the circumference of the first transmission member 1212 to enhance the reliability of clamping the cover 22.

[0068] As shown in Figure 10As shown, the third support 16 is a protective shell, which is arranged on the periphery of the rotating cover device 12, the first inclined surface 161 extends along the circumference of the protective shell, and the protective shell is provided with a third installation passage 162 for the rotating cover device 12 to pass through. The third support 16 is a protective shell, which is used to protect the components inside the protective shell.

[0069] As shown in the drawings, Figure 4 In an embodiment, the claw 151 comprises a hinged part 1511 and a hook part 1512 connected with each other, the hinged part 1511 is hinged with the first driving assembly 121, and the clamping part 223 is an annular groove, and the hook part 1512 at least partially extends into the annular groove and hooks the cover 22 at the third position 1513; wherein the clamping part 223 is an annular groove, so that the hook part 1512 can more easily complete the clamping cooperation with the groove wall of the annular groove, that is, the hook part 1512 can be clamped and cooperated with the groove wall at any position in the circumference of the annular groove.

[0070] As shown in the drawings, Figure 4 The bottom end of the claw 151 has a second inclined surface 1514, which extends upward from the outside to the inside and towards the first driving assembly 121, and the second inclined surface 1514 cooperates with the cover 22 when the lifting device 13 moves downward, so as to guide the claw 151 from the third position 1513 to the fourth position. In this embodiment, the second inclined surface 1514 is arranged at the bottom end of the claw 151, so that when the lifting device 13 drives the claw 151 to descend, the claw 151 will not collide with the top of the cover 22 and be damaged, and the second inclined surface 1514 will drive the claw 151 to move from the third position 1513 to the fourth position, until the hook part 1512 is separated from the cover 22, and the claw 151 will move to the third position 1513 under the action of the second reset member 152, so as to complete the clamping cooperation with the annular groove.

[0071] As shown in the drawings, Figure 3 , Figure 8 and Figure 9 In an embodiment, the first limiting part 111 has a plurality of first clamping teeth 1111, which extend upward, and the first clamping teeth 1111 are used to limit the cooperation with the first clamping groove 211 arranged on the bottom of the tank 21; wherein the first clamping teeth 1111 are used to limit the cooperation with the first clamping groove 211, so that the first limiting part 111 can limit the rotation of the tank 21 relative to the material tray 11.

[0074] According to another embodiment of the present application, a boss is arranged on the top of the cover 22, and the outer wall of the boss is provided with a plurality of clamping grooves arranged along the circumference of the boss, and the bottom surface of the rotating cap 1221 is provided with a recess cavity for accommodating the boss, and the inner wall of the recess cavity is inwardly protruding to form a plurality of clamping teeth arranged along the extension direction of the inner wall of the recess cavity, and the clamping teeth are used for limiting cooperation with the clamping grooves.

[0075] In addition, the present application also provides a control method of a pet feeding device, which is applied to the pet feeding device described above, and the pet feeding device further comprises a second driving assembly, the second driving assembly is in transmission connection with the material disc, one side of the material disc facing the rotating cap device is provided with an accommodation area for accommodating the can, the accommodation area is the first limiting part, and the second driving assembly is used for driving the material disc to rotate so that the accommodation area has a can opening station; the first driving assembly comprises a first driving part and a first transmission part connected with each other, and the rotating cap is in sliding cooperation with the first transmission part.

[0076] Referring to Figure 11 , Figure 11 The flowchart of the control method of the pet feeding device according to the first embodiment of the present application, the control method comprises the following steps:

[0077] S100, obtaining a can opening instruction, and controlling the second driving assembly to rotate so that the accommodation area reaches the can opening station;

[0078] The user can send an opening cover instruction to the pet feeder through a button on the pet feeder or a remote terminal, and when the pet feeder obtains the opening cover instruction, the second driving assembly drives the material tray to rotate so that the containing area reaches the opening cover station.

[0079] S200, controlling the lifting device to move downwardly by a third stroke;

[0080] The lifting device drives the first driving assembly to descend, and since the first driving assembly is in transmission connection with the cap screwing member, the cap screwing member is driven to descend, that is, the lifting device drives the cap screwing member to descend by a third stroke through the first driving assembly so that the cap screwing member and the cover body are in contact, and the second limiting part of the cap screwing member is in limiting cooperation with the cover body of the can on the material tray.

[0081] S300, controlling the first driving assembly to rotate in a first direction;

[0082] Since the second limiting part of the cap screwing member is in limiting cooperation with the cover body, when the first driving assembly drives the cap screwing member to rotate in the first direction, the cap screwing member can transmit the torque to the cover body, and since the first limiting part is in abutment with the can body, the cover body can rotate in the first direction relative to the can body; since the can body and the cover body are in rotary cooperation connection, the cover body rotates in the first direction relative to the can body, and the connection relationship can be released.

[0083] In the embodiment, the cover body 22 is in screw cooperation with the can body 21; in other embodiments, the cover body 22 is in rotary snap cooperation with the can body 21.

[0084] As shown in Figures 4-8 Since the cap screwing member and the first transmission member can slide in the up-down direction, in the process that the cap screwing member drives the cover body to rotate in the first direction, the first transmission member does not need to ascend with the ascending position of the cover body, because the cap screwing member will slide upward relative to the first transmission member with the ascending of the cover body.

[0085] According to an embodiment of the present application, the step S300 comprises:

[0086] S310, controlling the first driving assembly to rotate in the first direction so that the second limiting part is in limiting cooperation with the cover body;

[0087] S320, controlling the first driving assembly to rotate in the first direction.

[0088] If the lifting device drives the first transmission member to descend the third stroke, the second limiting part fails to limit the cap body, and the second limiting part is lifted by the cap body and slides upward relative to the first transmission member. At this time, the first driving member needs to drive the cap rotating member to rotate. In the rotating process, the second limiting part moves downward relative to the first transmission member at a position under the influence of the restoring force of the spring, so that the limiting cooperation between the second limiting part and the cap body is completed, and the subsequent rotation of the cap rotating member in the first direction driven by the first driving assembly can smoothly transmit the torque to the cap body.

[0089] In addition, the application further provides a control method of the pet feeder, which is applied to the pet feeder described above, and the pet feeder further comprises a second driving assembly, the second driving assembly is in transmission connection with the material disc, one side of the material disc towards the cap rotating device is provided with a containing area for containing the can, the containing area is the first limiting part, and the second driving assembly is used for driving the material disc to rotate so that the containing area has a capping station; the first driving assembly comprises a first driving member and a first transmission member which are connected with each other, the cap rotating member is in sliding cooperation with the first transmission member;

[0090] Referring to Figure 12 , Figure 12 FIG. 2 is a flowchart of a control method of a pet feeder according to a second embodiment of the application, and the control method comprises the following steps:

[0091] S100', a capping instruction is acquired, and the second driving assembly is controlled to rotate so that the containing area reaches the capping station;

[0092] A user can send a capping instruction to the pet feeder through a button on the pet feeder or a remote terminal. When the pet feeder acquires the capping instruction, the second driving assembly drives the material disc to rotate so that the containing area reaches the capping station.

[0093] In this embodiment, the positions of the uncapping station and the capping station are the same. In other embodiments, the positions of the uncapping station and the capping station are different.

[0094] S200', the lifting device is controlled to move downward by a fourth stroke;

[0095] The lifting device drives the first driving assembly to descend. Since the first driving assembly is in transmission connection with the cap rotating member, the cap rotating member is driven to descend together, that is, the lifting device drives the cap rotating member to descend by the fourth stroke through the first driving assembly, so that the cap body contacts the can body.

[0096] In this embodiment, the distances of the third stroke and the fourth stroke are the same. In other embodiments, the distances of the third stroke and the fourth stroke are different.

[0097] S300', control the first driving assembly to rotate in a second direction.

[0098] The first driving assembly drives the rotating cover to rotate, so that the second limiting part on the rotating cover can be limitedly matched with the cover body. Since the can body of the can and the first limiting part on the material disc abut, the first limiting part can limit the rotation of the can body relative to the material disc. Therefore, when the first driving assembly drives the rotating cover to rotate in the second direction, the rotating cover can transmit the torque to the cover body. Since the first limiting part abuts against the can body, the cover body can rotate in the second direction relative to the can body. The can body and the cover body are rotationally and matchingly connected, so that the rotation of the cover body in the second direction relative to the can body can restore the connection.

[0099] Since the rotating cover and the first transmission part can be slidably matched in the up-down direction, in the process that the rotating cover drives the cover body to rotate in the second direction, the first transmission part does not need to descend with the descending position of the cover body, because the rotating cover will slide downward relative to the first transmission part with the descending of the cover body under the action of gravity.

[0100] In the embodiment, the cover body 22 is threadedly matched with the can body 21. In other embodiments, the cover body 22 is rotationally and buckled matched with the can body 21.

[0101] The control method of the pet feeder of the present application, in combination with the structural design of the pet feeder, when the pet finishes eating, in order to avoid the open can body emitting odor, the pet feeder receives the cover instruction, controls the second driving assembly to rotate so that the containing area reaches the cover station, the pawl assembly clamps the cover body, controls the lifting device to drive the pawl assembly connected with the first driving assembly to move towards the can through the first driving assembly, when the lifting device moves downward by the fourth stroke to make the cover body and the can body contact, the first driving assembly drives the rotating cover to rotate so that the second limiting part on the rotating cover can be limitedly matched with the cover body. Since the can body of the can and the first limiting part on the material disc abut, the first limiting part can limit the rotation of the can body relative to the material disc. Therefore, the cover body can rotate in the second direction relative to the can body under the driving of the first driving assembly to connect the cover body and the can body, so that the automatic covering of the can is completed by the pet feeder without the participation of personnel.

[0102] According to another embodiment of the present application, the pet feeder further comprises a pawl assembly connected with the first driving assembly, the pawl assembly being used for clamping or releasing the cover, the pawl assembly being hinged with the first driving assembly, the pawl assembly comprising a pawl and a second reset member, the pawl being used for detachably connecting with a clamping part arranged on the cover, the pawl being movable between a third position matched with the clamping part and a fourth position disengaged from the clamping part, the second reset member applying an elastic reset force to the pawl for moving from the fourth position to the third position; the pet feeder further comprises a third support arranged on the outer periphery of the pawl, an inner wall of the third support being provided with a first inclined surface extending upwardly from outside to inside and toward the first driving assembly, the pawl being matched with the first inclined surface when the lifting device moves upwardly to guide the pawl from the third position to the fourth position; the pawl comprises a first station, a second station and a third station arranged in sequence and spaced apart from bottom to top; the material tray is further provided with a garbage port, and a garbage bin is arranged below the material tray, an opening of the garbage bin facing the garbage port; the S400 comprises:

[0104] S420, controlling the second driving assembly to drive the material tray to rotate so as to rotate the garbage port below the cover;

[0105] S430, controlling the lifting device to drive the pawl to move upwardly to the third station so as to release the cover under the guidance of the guide surface.

[0106] If the cover needs to be recycled, after the lifting device drives the first transmission member to move downwardly by a third stroke and the pawl is in the first station, the cover is disengaged from the rotation with the tank, the lifting device is controlled to drive the pawl to move upwardly to the second station, at this time, the cover fixed by the pawl also moves upwardly with the pawl, the first limiting part is further provided with a feeding station, at this time, the tank can be rotated to the feeding station without interference with the cover, when the first limiting part is in the feeding station, the garbage port is below the cover, the lifting device is controlled to drive the pawl to move upwardly to the third station, in the process of the pawl moving upwardly from the second station to the third station, the pawl moves from the third position to the fourth position under the guidance of the first inclined surface to disengage the clamping part of the cover, so that the cover can be smoothly dropped into the garbage bin through the garbage port, thereby realizing the recycling of the cover.

[0107] According to another embodiment of the present application, after the opened can is rotated to the feeding station, the pet starts to eat, and after the pet finishes eating, the can is rotated to below the cover, the cover is restored to be in the rotating cooperation with the can body through the cooperation of the lifting device and the cover rotating device, the pawl still maintains the clamping of the cover, the lifting device drives the pawl to rise to the second station, at this time, the assembled can rises together with the pawl, the garbage port is rotated to below the can, and the lifting device drives the pawl to rise to the third station, in the process that the pawl rises from the second station to the third station, the pawl moves from the third position to the fourth position under the guidance of the first inclined surface, so that the clamping cooperation between the pawl and the cover is released, so that the can can smoothly fall into the garbage bin through the garbage port, and since the can body and the cover are in the sealed connection, the peculiar smell is not generated.

[0108] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the concept of the present application, and directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present application.
