[0004] With an increasing number of people keeping pets, the demand for pet food is also increasing. There are many different types of pet food available. Canned food is generally used to hold wet food such as meat paste. Wet food is soft and has a rich flavor, making it more attractive to pets and stimulating their appetite. Consequently, canned food has become an indispensable food for improving a pet's diet. However, opening cans still relies on the pet owner or breeder to manually open the can. If the pet owner or breeder doesn't have the time or convenience to open the can every time they feed their pet, the pet will lose access to the wet food enclosed in the can. Therefore, there is a need for an animal feeding system that can automatically open canned food.

[0059] The present application proposes an animal feeding system.

[0060] In the prior art, the cans still rely on the pet owner or breeder to manually open the cans. If the pet owner or breeder does not have the time or convenience to open the cans to feed the pets every time, the pets will not be able to obtain the wet food packaged in the cans.

[0061] To address the aforementioned technical issues, the present invention employs a can pressing device to abut the can body, restricting its vertical movement, and a lid-pushing device to pull the lid body vertically, separating the lid from the can body. This automatically opens the food container for pets to eat without requiring human intervention. Specifically, the lid-pushing device includes a lid-pushing body and a first drive assembly. When the engaging assembly engages the lid body, the first drive assembly drives the lid-pushing body to move from a first position toward a second position, separating the lid from the can body and opening the food container.

[0062] The above technical solution will be described in detail below with reference to the accompanying drawings.

[0063] In an embodiment of the present application, as shown in Figures 1 to 9, the animal feeding system is used for a food container. The food container includes a cover 2000 and a can 1000 that are snap-fitted together. The animal feeding system includes a can pressing device 10 and a lid pulling device 20. The can pressing device 10 is used to abut against the can 1000 to limit the vertical movement of the can 1000. This technical solution is applicable to food containers in which the cover 2000 and the can 1000 are snap-fitted together. It is understood that the food container can be opened by moving the cover 2000 and the can 1000 away from each other, or by moving one of the cover 2000 and the other away from each other. In this embodiment, the can pressing device 10 abuts against the can 1000 to limit its vertical displacement, and the lid pulling device 20 engages with the cover 2000, causing the cover 2000 to move vertically and separate from the can 1000, thereby opening the food container.

[0064] In this embodiment, the sliding cover device 20 includes a sliding cover body 100 and a first drive assembly 300. Specifically, the sliding cover body 100 is movably connected to the clamping assembly 200. The clamping assembly 200 has a clamping state and a loose state. The clamping assembly 200 can switch between the clamping state and the loose state. In the clamping state, the clamping assembly 200 is engaged with the cover body 2000, and in the loose state, the clamping assembly 200 is separated from the cover body 2000. The first drive assembly 300 is transmission-connected to the sliding cover body 100 and enables the sliding cover body 100 to have a first position and a second position in a vertical direction, with the first position being below the second position. In the first position, the clamping assembly 200 is used to engage with the cover body 2000. In the second position, the cover body 2000 is separated from the can body 1000. The first drive assembly 300 drives the sliding cover body 100 to move between the first position and the second position.

[0065] The first drive assembly 300 can be a motor-driven lifting structure or a cylinder-driven lifting structure, which is not limited in this embodiment. In a specific implementation process, with reference to Figures 8 and 9, the first drive assembly 300 drives the sliding cover body 100 to move in a vertical direction, and causes the sliding cover body 100 to have a first position and a second position in its movement range, and a certain distance between the first position and the second position to ensure that the cover body 2000 and the sliding cover body 100 are completely separated from the tank body 1000. It is understandable that after the cover body 2000 and the sliding cover body 100 are separated from the tank body 1000, the tank body 1000 can be moved to the feeding position of the animal feeding system for the pet to eat. The cover body 2000 has a card slot, and the locking assembly 200 is connected to the cover body 2000 through the card slot, so that when the first driving assembly 300 drives the sliding cover body 100 to move vertically, it can pull the cover body 2000 to move synchronously. At the same time, the can pressing device 10 limits the movement of the can body 1000 in the vertical direction. In this way, the sliding cover body 100 can pull the cover body 2000 away from the can body 1000 to open the food container.

[0066] In this embodiment, as shown in Figures 11, 16, or 22, the food container further includes a sealing membrane 3000 for sealing the receiving cavity. A portion of the sealing membrane 3000 is connected to the lid 2000, while another portion of the sealing membrane 3000 is at least partially connected to the tank body 1000. Thus, when the lid 2000 of the animal feeding system is opened, the sealing membrane 3000 and the lid 2000 are removed from the tank body 1000 together. Specifically, the tank pressing device 10 is configured to abut against the top of the support portion of the tank body 1000 to restrict vertical movement of the tank body 1000. The lid pulling device 20 cooperates with the lid 2000 and moves vertically, pulling the lid 2000 away from the tank body 1000. The sealing membrane 3000 moves synchronously with the lid 2000 and leaves the tank body 1000, exposing the food in the receiving cavity for consumption by the pet, thereby achieving the effect of automatically opening the food container. In other embodiments, the tank body and lid can be used directly to seal the food. In this embodiment, the supporting portion of the tank body 1000 is the first flange portion 1210 of the supporting member 1200 .

[0067] In this embodiment, a food container is placed within the animal feeding system and is driven to move below the sliding lid device 20. The food container can be moved by rotating a turntable, or manually, for example, which is not limited in this embodiment. At this point, the sliding lid body 100 is positioned away from the food container, which serves as the initial position of the sliding lid body 100. When the animal feeding system controls the opening of the food container, the first drive assembly 300 drives the sliding lid body 100 downward from the initial position to the first position, which serves as the first stroke of the sliding lid device 20. It will be appreciated that, in order for the engaging assembly 200 to smoothly engage with the engaging slot of the lid body 2000, the engaging assembly 200 is in a released state before reaching the first position. When the sliding lid body 100 reaches the first position, the locking assembly 200 switches from a loose state to a locked state, locking the lid body 2000. After the locking assembly 200 locks the lid body 2000, the first driving assembly 300 drives the sliding lid body 100 upward. Simultaneously, the locking assembly 200 pulls the lid body 2000 upward. Furthermore, the can pressing device 10 restricts the movement of the can body 1000, forcing the lid body 2000 away from the can body 1000, thereby opening the food container. The sliding lid body 100 and the lid body 2000 move from the first position to the second position, which constitutes the second stroke of the sliding lid device 20. It will be appreciated that during the second stroke, when the sliding lid body 100 is in the second position, the locking assembly 200 is in a locked state to prevent the lid body 2000 from falling. The can body 1000 can then be moved to the feeding position of the animal feeding system for consumption by the pet.

[0068] Furthermore, after the pet finishes eating, the tank body 1000 moves from the feeding position to below the sliding cover device 20. The first drive assembly 300 drives the sliding cover body 100 and the cover body 2000 to descend from the second position to the first position, which constitutes the third stroke of the sliding cover device 20. It will be appreciated that during this stroke, the locking assembly 200 is in a locked state to prevent the cover body 2000 from falling. After the sliding cover body 100 reaches the first position, the cover body 2000 is locked to the tank body 1000. The locking assembly 200 switches from the locked state to a loose state and moves away from the cover body 2000. The first drive assembly 300 then drives the sliding cover body 100 and the locking assembly 200 to ascend, possibly to the initial position or the second position, which constitutes the fourth stroke of the sliding cover device 20. It will be appreciated that in one embodiment, the food in the tank body 1000 may be completely consumed. In this case, the animal feeding system may drive the food container to the discard position for disposal. In another embodiment, there may be a situation where there is still food in the tank 1000. In this case, the animal feeding system can drive the food container to a refrigerated storage position to ensure the quality of the food.

[0069] In other embodiments, when the sliding cover body 100 reaches the first position, the snap assembly 200 moves downward with the cover body 2000 and then abuts against the can body 1000, and then the sliding cover body 100 continues to move downward until it reaches the first position. During this process, the sliding cover body 100 can achieve snap-fit ​​cooperation between the cover body 2000 and the can body 1000.

[0070] In some embodiments, as shown in Figures 3 and 4, the lid-lifting device 20 further includes a second drive assembly 400, which includes a second motor 410 and a first cam 420. The second motor 410 is connected to the first cam 420 to drive the first cam 420 to rotate. The outer peripheral wall of the first cam 420 is formed with a protrusion 421 and a recessed portion 422 extending in a direction perpendicular to the axial direction of the second motor 410. The clamping assembly 200 includes a clamping member 210, which includes a clamping portion 211 and a pushing portion 212 connected to each other. Specifically, the clamping member 210 extends in the radial direction of the first cam 420. The pushing portion 212 is provided at one end of the clamping member 210 and is close to the first cam 420, for abutting against the protrusion 421 and the recessed portion 422. The clamping portion 211 is provided at the other end of the clamping member 210 and is away from the first cam 420 for clamping the lid 2000. In the clamped state, the first cam 420 drives the protrusion 421 to abut against the pushing portion 212, and the pushing portion 212 drives the locking portion 211 to engage with the cover body 2000. In the loosened state, the first cam 420 drives the recessed portion 422 to abut against the pushing portion 212, and the pushing portion 212 drives the locking portion 211 to separate from the cover body 2000.

[0071] 5 and 7 , the output shaft of the second motor 410 is connected to the first cam 420, driving the first cam 420 to rotate. During the rotation of the first cam 420, the protrusion 421 and the recess 422 of the first cam 420 alternately abut against the push portion 212 of the clamping member 210, thereby switching the clamping assembly 200 between a clamped state and a loosened state. In this embodiment, a plurality of clamping members 210 are spaced apart along the circumferential direction of the first cam 420 to ensure that the clamping member 210 can smoothly pull the cover 2000 after being engaged with the cover 2000. Accordingly, the number of protrusions 421 and recesses 422 is the same as or greater than the number of clamping members 210, ensuring that each clamping member 210 abuts against a protrusion 421 or recess 422 during the rotation of the cam. In this embodiment, the engaging member 210 is engaged with the groove of the cover 2000. In this embodiment, as shown in FIG16 , in the locked state, the engaging assembly 200 is engaged with the groove 2400, and in the loose state, the engaging assembly 200 is separated from the groove 2400. It is understood that the number of grooves defined in the cover 2000 may be the same as or greater than the number of the engaging members 210; or the groove of the cover 2000 may be a single integral groove, ensuring that each engaging member 210 is engaged with its corresponding groove in the locked state.

[0072] In a specific implementation, the axis of the second cam 430 coincides with the axis of the sliding cover body 100, and the connecting member 210 extends in a radial direction consistent with the second cam 430, moving in the radial direction. Furthermore, the sliding cover body 100 is sleeve-shaped and has a first internal accommodating space. The second drive assembly 400 and the engaging assembly 200 are disposed within the first accommodating space. This allows for efficient space utilization and helps reduce the overall volume of the animal feeding system. The lower wall of the first accommodating space is formed with a guide rail 140, and the connecting member 210 slidably engages with the guide rail 140. Specifically, in one embodiment, the lower wall of the sliding cover body 100 is formed with a chute, and the connecting member 210 is slidably connected within the chute. The inner wall of the chute forms the guide rail 140, allowing the connecting member 210 to slide along the inner wall of the chute. Specifically, in one embodiment, the lower wall of the sliding cover body 100 facing away from the first accommodating space is connected to a limiting plate 120, and the bottom of the sliding cover body 100 is recessed upward to form the first accommodating space. The limiting plate 120 is disposed at the bottom of the first accommodating space. In this case, the upper surface of the limiting plate 120 constitutes the lower wall of the first accommodating space. In another embodiment, the lower wall of the sliding cover body 100 facing away from the first accommodating space is connected to the limiting plate 120, and the bottom of the sliding cover body 100 is recessed toward the first accommodating cavity, thereby forming a slide groove between the limiting plate 120 and the sliding cover body 100. The clip 210 slides within the slide groove, and the inner wall of the slide groove and the limiting plate 120 form a guide rail 140, along which the clip 210 moves.

[0073] As shown in FIG6 , a second avoidance groove 121 is provided at the center of the limiting plate 120 , and the second avoidance groove 121 is used to avoid the handle portion 2500 of the cover body 2000 as shown in FIG16 .

[0074] In this embodiment, the first cam 420 rotates so that the protrusion 421 abuts against the pushing portion 212, thereby driving the clamping member 210 to move, and causing the locking portion 211 to extend out of the sliding cover body 100 and clamp the cover body 2000. When the first cam 420 continues to rotate so that the recessed portion 422 is opposite to the pushing portion 212, the clamping member 210 needs to retract so that the pushing portion 212 abuts against the recessed portion 422. Therefore, in this embodiment, the engaging assembly 200 further includes a reset member 220. Specifically, the reset member 220 has a certain elasticity and is connected to the engaging member 210. When the protruding portion 421 drives the engaging member 210 to move, the reset member 220 is compressed and has a certain elastic force. When the first cam 420 continues to rotate and the recessed portion 422 is opposite to the pushing portion 212, the reset member 220 returns to its original state and releases the elastic force, thereby driving the engaging member 210 to move in the opposite direction and cooperating with the rotation of the first cam 420 to make the pushing portion 212 abut against the recessed portion 422. The reset member 220 can be made of elastic rubber, silicone, or a spring, etc., which is not limited in this embodiment.

[0075] In a specific implementation, the clamping member 210 is further formed with a fixing portion 215 extending upward along the motor axis of the second motor 410. One end of the reset member 220 is connected to the sliding cover body 100, and the other end of the reset member 220 is connected to the fixing portion 215. The reset member 220 applies an elastic reset force to the clamping member 210 to move it from a clamped state to a loose state. Specifically, a mounting plate is formed on the inner wall of the first accommodating space of the sliding cover body 100. An elongated hole is defined in the lower wall of the first accommodating space. The elongated hole extends in the same direction as the clamping member 210. The top surface of the clamping member 210 protrudes upward to form the fixing portion 215, which slides within the elongated hole. One end of the reset member 220 is connected to the mounting plate, and the other end is connected to the fixing portion 215, thereby compressing the reset member 220 during the movement of the clamping member 210 from the loose state to the clamping state, so that the reset member 220 has a reset force to restore the original state. When the clamping member 210 is converted from the clamping state to the loose state, the protrusion 421 of the first cam 420 gradually moves away from the pushing portion 212. At this time, the reset member 220 is restored to its original state due to the reset force, thereby driving the clamping member 210 to move in the opposite direction. In this way, the pushing portion 212 of the clamping member 210 abuts the recessed portion 422 of the first cam 420, that is, the clamping member 210 is in the loose state. In addition, it is understandable that the end surface of the pushing portion 212 and the side surface of the protrusion 421 are both arranged as arc surfaces, thereby ensuring that the clamping member 210 switches smoothly between the clamping state and the loose state.

[0076] In this embodiment, as shown in Figure 6, the locking portion 211 is formed with a first guide slope 213 and a support surface 214 that are interconnected. The first guide slope 213 extends upward from the edge of the locking member 210 to the support surface 214. When the sliding cover body 100 moves to the first position, the first guide slope 213 is used to cooperate with the cover body 2000 to guide the cover body 2000 into the support surface 214.

[0077] It is understandable that in practice, the placement of the food container is not precise. However, the sliding cover body 100 needs to cooperate with the cover body 2000 of the food container to ensure that the engaging portion 211 of the engaging member 210 can be smoothly engaged with the groove of the cover body 2000. In this embodiment, the first guiding inclined surface 213 cooperates with the cover body 2000 to facilitate the engagement of the peripheral surface of the sliding cover body 100 with the top of the cover body 2000, thereby facilitating the insertion of the engaging portion 211 into the cover body 2000. At the same time, the supporting surface 214 cooperates and abuts with the cover body 2000, ensuring that the sliding cover body 100 can smoothly pull the cover body 2000.

[0078] Furthermore, a guide portion 110 is provided at the bottom end of the sliding cover body 100 for engaging with the cover body 2000. The guide portion 110 is adapted to move within the inner circumferential wall of the cover body 2000 to allow the sliding cover body 100 to be moved in and out of the cover body 2000. The guide portion 110 is provided with a first through hole 111. In a tightened state, an engaging portion 211 can extend from the first through hole 111 and engage with the cover body 2000. In a specific embodiment, the guide portion 110 is provided at the bottom edge of the sliding cover body 100 and is arranged circumferentially along the sliding cover body 100. In a loosened state, the engaging portion 211 is located within the first through hole 111, or the end of the engaging portion 211 is flush with the guide portion 110, thereby preventing the engaging portion 211 from interfering with the sliding cover body 100 entering the cover body 2000.

[0079] In a more specific implementation process, as shown in Figure 16, the cover body 2000 includes a side wall portion 2100, a cover tray portion 2200 and a cover flange portion 2300. The cover tray portion 2200 is connected to the inner peripheral wall of the side wall portion 2100. The cover tray portion 2200 divides the cover body 2000 into a recessed space with an opening open upward and a lower space with an opening open downward. The cover flange portion 2300 is arranged in the recessed space. One end of the cover flange portion 2300 is connected to the side wall portion 2100, and the other end of the cover flange portion 2300 extends inward in a direction away from the cover body 2000. The cover flange portion 2300, the side wall portion 2100 and the cover tray portion 2200 enclose a groove 2400; in the clamped state, the guide portion 110 extends into the groove 2400 and is clamped with the cover flange portion 2300, so that the cover body 2000 can be pulled to move when the cover main body 100 is pulled up.

[0080] Furthermore, the guide portion 110 is formed with a second guide slope 112, which slopes vertically upward from the bottom of the sliding lid body 100 toward the tank pressing device 10. When the sliding lid body 100 moves to the first position, the second guide slope 112 cooperates with the lid body 2000 to move the sliding lid body 100 into the lid body 2000. Specifically, the second guide slope 112 and the first guide slope 213 are both located at the edges of the lid body 2000. The second guide slope 112 is respectively connected to the outer side wall and the outer bottom wall of the sliding lid body 100 and contacts the lid body 2000, thereby guiding the sliding lid body 100 to enter and exit the lid body 2000 smoothly. In this embodiment, the second guide slope 112 is arranged in conjunction with the first guide slope 213, and the inclination direction and angle of the two slopes are consistent, so that the bottom of the sliding lid body 100 can enter and exit the lid body 2000 smoothly.

[0081] Optionally, the second drive assembly 400 also includes a second cam 430, the first cam 420 has a camshaft 423, the second cam 430 is sleeved on the camshaft 423, the second motor 410 drives the first cam 420 and the second cam 430 to move synchronously, and the animal feeding system also includes a first detection assembly 130, the first detection assembly 130 includes a first signal transmitter 131 and a first signal receiver 132, the first signal transmitter 131 is fixedly connected to the second cam 430, and the first signal receiver 132 is fixedly connected to the sliding cover body 100, and in the clamped state and / or loosened state, the first signal transmitter 131 and the first signal receiver 132 are correspondingly arranged.

[0082] In a specific implementation, the second cam 430 is located above the first cam 420. The camshaft 423 of the first cam 420 extends upward along the axial direction, so that the second cam 430 is sleeved on the camshaft 423. A limiting plane is defined between the camshaft 423 and the second cam 430 to prevent circumferential rotational displacement of the first cam 420 and the second cam 430 during rotation, thereby allowing the second motor 410 to drive the first cam 420 and the second cam 430 to rotate synchronously. In this embodiment, the movement of the engaging assembly 200 is detected by the first detection assembly 130. Specifically, the rotation of the second cam 430 causes the first signal transmitter 131 to trigger the first signal receiver 132, thereby detecting the movement of the engaging assembly 200. Specifically, the first signal transmitter 131 is fixedly connected to the second cam 430, and the second cam 430 moves synchronously with the first cam 420. When the first cam 420 prompts its protruding portion 421 to drive the clamping member 210 so that it is in a clamped state, the first signal transmitter 131 fixedly connected to the second cam 430 and the first signal receiver 132 are correspondingly arranged. At this time, the first detection component detects that the clamping component 200 is in a clamped state; or, when the first cam 420 prompts its recessed portion 422 to drive the clamping member 210 so that it is in a loose state, the first signal transmitter 131 fixedly connected to the second cam 430 and the first signal receiver 132 are correspondingly arranged. At this time, the first detection component detects that the clamping component 200 is in a loose state.

[0083] In this embodiment, as shown in Figure 7, the first detection component 130 includes two first signal transmitters 131, wherein the first signal transmitter 131 located above the protrusion 421 is used to detect whether the locking component is in a locked state, and the first signal transmitter 131 located above the recessed portion 422 is used to detect whether the locking component is in a loose state.

[0084] In this embodiment, as shown in FIG7 , the first detection assembly 130 is a mechanical switch, the first signal transmitter 131 is a mechanical protrusion, and the first signal receiver 132 is a mechanical button. Specifically, the mechanical protrusion is disposed on the peripheral sidewall of the second cam 430. In practice, the peripheral sidewall of the second cam 430 is provided with a protrusion. The mechanical button is on the sliding cover body 100 and located on one side of the second cam 430. Thus, rotation of the second cam 430 causes the mechanical protrusion to contact the mechanical button, thereby triggering the first signal receiver 132 to generate the first detection signal. It will be appreciated that, as needed, multiple mechanical protrusions may be disposed on the peripheral sidewall of the second cam 430 at intervals along the circumferential direction. In this way, each rotation of the second cam 430 causes the mechanical protrusion to contact the mechanical button multiple times, thereby satisfying the detection requirements of the engaging assembly 200. Furthermore, in this embodiment, the number of mechanical protrusions is consistent with the number of protrusions 421, and the angles of the protrusions extending in the same direction are consistent.

[0085] Furthermore, the first detection component 130 includes two first signal receivers 132, the number of first signal transmitters 131 is the same as the number of the clips 210 and is N, and in the projection on the horizontal plane, the first signal transmitters 131 and the clips 210 are equally spaced along the axis of the second motor 410, and the line connecting the axis of the second motor 410 and one of the first signal receivers 132 is L1, and the line connecting the axis of the second motor 410 and the other first signal receiver 132 is L2, wherein the central angle defined between L1 and L2 is α, and α and N satisfy the following relationship: α=180 / N.

[0086] In this embodiment, N is 4, where α is 45°, and the first signal transmitters 131 are evenly spaced on the second cam 430. When the first signal transmitter 131 triggers the first signal receiver 132 located above the protrusion 421, the first cam 420 drives the latching member 210 to extend and engage with the cover 2000. At this point, the latching assembly 200 is in a locked state, and the first drive assembly 300 can drive the sliding cover body 100 to rise, simultaneously with the cover 2000. The second cam 430 rotates another 45°, and the first signal transmitter 131 triggers the first signal receiver 132 located above the recessed portion 422. The latching member 210 engages with the recessed portion 422 of the first cam 420. At this point, the latching assembly 200 is in a released state, and the first drive assembly 300 can further drive the sliding cover body 100 away from the cover 2000. During this process, the pull-lid main body 100 moves from the first position to the second position, pulling the cover body 2000 away from the can body 1000 , and then moves from the second position to the first position, covering the cover body 2000 on the can body 1000 .

[0087] Furthermore, the first drive assembly 300 includes a first motor 310 and a first transmission member 340 that are transmission-connected. The first transmission member 340 is fixedly connected to the sliding cover body 100. The first motor 310 drives the first transmission member 340 to move in the vertical direction. The pressure member 600 is in the shape of a sleeve having an internal second accommodating space. The pressure member 600 is open at one end close to the food container and has a second through hole 611 formed at the other end that passes through the upper and lower ends. The sliding cover body 100 is arranged in the second accommodating space. The first transmission member passes through the second through hole 611 to drive the sliding cover body 100 to move in the vertical direction.

[0088] The sliding lid body 100 is located within the second accommodation space of the pressure member 600 and moves within the second accommodation space. As will be appreciated, the bottom end of the pressure member 600 is open, facilitating connection between the sliding lid body 100 and the lid body 2000, thereby opening the lid body 2000. The pressure member 600 is sleeved onto the exterior of the sliding lid body 100, with its bottom end surface abutting the support portion of the can body 1000. As will be appreciated, in horizontal projection, the outer wall of the support portion is located outside the pressure member 600, ensuring effective contact between the pressure member 600 and the support portion, thereby effectively limiting the vertical displacement of the can body 1000.

[0089] As shown in Figure 4, the top of the pressure member 600 is provided with a second through-hole 611. In one embodiment, the pressure member 600 has an integral top portion with the second through-hole 611 disposed therein. The first motor 310 is mounted on the top portion of the pressure member 600, on a side facing away from the second receiving cavity. In another embodiment, the animal feeding system further comprises a fixing member 610, to which the pressure member 600 and the sliding lid body 100 are respectively fixedly connected. The fixing member 610 is screwed or snap-fitted to the top portion of the pressure member 600, thereby sealing the second receiving cavity at the top portion. The first motor 310 is mounted on a side of the fixing member 610 facing away from the fixing member 610. The first motor 310 drives the sliding lid body 100 to move between the first position and the second position via a first transmission member. The first transmission member may be a gear transmission mechanism, a conveyor belt mechanism, or the like, though this is not limited in this embodiment. It is sufficient that the sliding lid body 100 is driven by the first motor 310 to move up and down. In this embodiment, the fixing member 610 simultaneously connects the pressure member 600 and the sliding lid body 100, so that the movement of the pressure member 600 can drive the movement of the sliding lid body 100. Specifically, during the separation of the tank body and the lid body of this embodiment of the animal feeding system, the pressure member 600 moves downward to abut the support portion of the tank body 1000. At this time, the pressure member 600 drives the sliding lid body 100 to move downward, and then the sliding lid body 100 moves downward again to reach the first position. After the engaging assembly 200 engages with the lid body, the sliding lid body 100 moves upward to separate the tank body 1000 and the lid body 2000.

[0090] In this embodiment, the bottom of the pressure member 600 is formed with a flange 620 extending outward in the circumferential direction. The flange 620 is used to abut the support portion of the can body 1000 to increase the contact area between the pressure member 600 and the support portion. In this embodiment, to ensure the effectiveness of the abutment, the top surface of the support portion is flat, which also facilitates the abutment of the flange 620 and the support portion. Specifically, the bottom end of the pressure member 600 is bent in a direction away from the axis to form the flange 620. The pressure member 600 surrounds the sliding cover body 100 and the cover body 2000 in the second storage space. The flange 620 abuts the support portion to limit the vertical and upward displacement of the can body 1000.

[0091] Furthermore, the fixing member 610 is provided with a second through hole 611, the first transmission member includes a first gear 320 and a first rack 330, the first motor 310 is installed on the fixing member 610, the output shaft of the first motor 310 is connected to the first gear 320, the first rack 330 has a first surface and a second surface arranged opposite to the first surface, the first surface is engaged with the first gear 320 for transmission, and the surface of the fixing member 610 facing the first motor 310 forms a limiting portion 612, the limiting portion 612 is arranged close to the second surface for limiting the first rack 330 to move in a direction away from the first gear 320, and the first rack 330 passes through the second through hole 611 to drive the sliding cover body 100 to move in the vertical direction.

[0092] In a specific embodiment, the first rack 330 extends vertically, with one end of the first rack 330 connected to the top of the sliding lid body 100. The other end of the first rack 330 is disposed through the second through-hole 611, allowing the first rack 330 to slide along the second through-hole 611. The first motor 310 drives the first rack 330 to move vertically between the first position and the second position via the first gear 320, further moving the sliding lid body 100. The fixing member 610 is connected to the limiting portion 612, which contacts the second surface of the first rack 330 to prevent the first rack 330 from shifting horizontally. This prevents horizontal shaking of the sliding lid body 100 and improves the stability of the first rack 330 and the movement of the sliding lid body 100. It also ensures that the first rack 330 is always meshed with the first gear 320, ensuring the effectiveness of the first motor 310 in driving the first rack 330 to move. It can be understood that the first surface of the first rack 330 is provided with gear teeth and is used to engage with the first gear 320 , and the second surface is a plane to facilitate cooperation with the limiting portion 612 .

[0093] In one embodiment, the limiting portion 612 includes a third roller 613, which can roll with the first rack 330 to reduce friction. Specifically, the peripheral sidewall of the third roller 613 contacts the second surface of the first rack 330, allowing the first rack 330 and the third roller 613 to roll with each other, thereby reducing friction. In a specific implementation, the third roller 613 is fixed to the fixed member 610 and rotates relative to the fixed member 610. In another embodiment, the limiting portion 612 includes a ball bearing, which contacts the first rack 330, further reducing friction.

[0094] Optionally, the animal feeding system further includes a second detection assembly 630, which includes a second signal transmitter 631 and a second signal receiver 632. The second signal transmitter 631 is fixedly connected to the first rack 330, and the second signal receiver 632 is fixedly connected to the fixing member 610. The second detection assembly 630 is used to cooperate with the first drive assembly 300 to control the movement of the sliding cover body 100.

[0095] The second detection component 630 can be a photoelectric sensor or a mechanical switch, etc., which is not limited in this embodiment, and only needs to ensure smooth triggering. In a specific implementation, the second detection component 630 is a mechanical switch, such as a travel switch. Specifically, the second signal transmitter 631 is a mechanical protrusion, and the second signal receiver 632 is a mechanical button. In the first position, the second signal transmitter 631 and the second signal receiver 632 abut. When the first rack 330 moves until the second signal transmitter 631 triggers the second signal receiver 632, the second signal receiver 632 is triggered to generate a second detection signal; in this embodiment, the second detection signal is a signal that detects that the sliding cover body 100 has reached the first position.

[0096] In one embodiment, two second signal transmitters 631 and two second signal receivers 632 are provided, wherein one second signal transmitter 631 is provided on the first rack 330 and located above the fixing member 610, and one second signal receiver 632 is installed on the fixing member 610 and located on the side of the fixing member 610 facing away from the second receiving space. In this case, the second signal transmitter 631 is used to trigger the second signal receiver 632. Another second signal transmitter 631 is provided on the first rack 330 and located below the fixing member 610, or another second signal transmitter 631 is provided on the top surface of the sliding cover body 100, and another second signal receiver 632 is installed on the fixing member 610 and located on the side of the fixing member 610 facing the second receiving space. In this case, the second signal transmitter 631 is used to trigger the second signal receiver 632. In another embodiment, the first rack 330 is equipped with a second signal transmitter 631, and the fixing member 610 is provided with two second signal receivers 632 with a vertical spacing distance. When the sliding cover body 100 is in the first position, the second signal transmitter 631 triggers one of the second signal receivers 632, and when the sliding cover body 100 is in the second position, the second signal transmitter 631 triggers the other second signal receiver 632.

[0097] Based on the above, when the sliding cover body 100 moves to the first position, the second signal transmitter 631 and the second signal receiver 632 are correspondingly arranged to generate a detection signal. When the sliding cover body 100 moves to the second position, another second signal transmitter 631 and another second signal receiver 632 are correspondingly arranged to generate a detection signal.

[0098] Optionally, the tank pressing device 10 includes a pressure piece 600 and a third drive assembly 500. The outer peripheral wall of the tank body 1000 is provided with a support portion. The third drive assembly 500 is transmission-connected to the pressure piece 600 so that the pressure piece 600 has a third position and a fourth position in the vertical direction. In the third position, the pressure piece 600 abuts against the support portion to limit the movement of the tank body 1000 in the vertical direction. In the fourth position, the pressure piece 600 is separated from the support portion, and the third drive assembly 500 drives the pressure piece 600 to move between the third position and the fourth position.

[0099] During the specific implementation, the support portion is fixed to the outer peripheral wall of the tank body 1000, and the support portion protrudes from the outer peripheral wall to facilitate the pressure member 600 to move from top to bottom and abut against the top surface of the support portion. Specifically, the bottom of the pressure member 600 abuts against the top surface of the support portion. The third drive assembly 500 drives the pressure member 600 to move up and down, and the third position is located below the fourth position. The third drive member drives the pressure member 600 to move from the fourth position to the third position. The pressure member 600 moves from the direction away from the support portion to the direction close to the support portion and abuts against the support portion. This process is regarded as the fifth stroke of the pressure member 600. The third drive assembly 500 drives the pressure member 600 to move from the third position to the fourth position. The pressure member 600 moves from the support portion to the direction away from the support portion. This process is regarded as the sixth stroke of the pressure member 600. Among them, the third drive member can be a motor drive structure or a cylinder lifting mechanism, which is not limited in this embodiment.

[0100] Furthermore, the third drive assembly 500 includes a third motor 510 and a second transmission member, the second transmission member includes a second gear 520 and a second rack 530, the output shaft of the third motor 510 is transmission-connected to the second gear 520, the pressure member 600 is fixedly connected to the second rack 530, and the second gear 520 and the second rack 530 are meshed and driven to drive the pressure member 600 to move in the vertical direction.

[0101] In this embodiment, the third motor 510 drives the pressure member 600 to move between the third position and the fourth position through the second transmission member. Specifically, the second rack 530 is vertically extended and fixedly installed on the outer wall of the pressure member 600. The third motor 510 drives the second gear 520 to rotate, so that the second rack 530 moves in the vertical direction, thereby realizing the movement of the pressure member 600 between the third position and the fourth position.

[0102] Optionally, the animal feeding system further comprises a sleeve-shaped housing 900 having an internal third accommodation space. The third motor 510 is mounted on the housing 900, and the can pressing device 10 and the lid pulling device 20 are disposed in the third accommodation space. In a specific implementation, the housing 900 encloses the exterior of the pressing member 600 via the third accommodation space. The third motor 510 is mounted on the housing 900. The housing 900 defines a first avoidance groove 910 to avoid the second rack 530, thereby allowing the second rack 530 to slide within the first avoidance groove 910.

[0103] As will be appreciated, the sliding lid body 100 is located within the second accommodation space of the pressure member 600 and also moves up and down within the second cavity. This creates a gap between the outer wall of the sliding lid body 100 and the inner wall of the second accommodation space. This may cause the sliding lid body 100 to wobble during vertical movement, preventing it from entering the lid body 2000. This could result in the engaging member 210 being unable to engage with the lid body 2000, and thus preventing the food container from being opened. In this embodiment, the animal feeding system further includes a first travel assembly 700, which includes a first roller 710 mounted on the sliding lid body 100 and configured to roll with the pressure member 600 to reduce friction generated during relative movement between the sliding lid body 100 and the pressure member 600.

[0104] 4 and 6 , the present embodiment provides a first running assembly 700 on the sliding cover body 100 and contacts the pressure member 600 to limit the horizontal displacement of the sliding cover body 100, thereby providing a good position limiting and guiding effect on the sliding cover body 100. Specifically, the first running assembly 700 further includes a first mounting seat 720, which is fixed to the side wall of the sliding cover body 100 by screws, and a first roller 710 is mounted within the first mounting seat 720, with the outer peripheral side wall of the first roller 710 contacting the inner wall of the pressure member 600. When the sliding cover body 100 moves up and down, the first roller 710 rolls along the pressure member 600, reducing friction between the sliding cover body 100 and the pressure member 600, and further providing a position limiting effect on the sliding cover body 100, thereby improving the stability of the sliding cover body 100 when moving up and down. It is understood that, depending on actual needs, the first mounting base 720 may be provided with a plurality of first rollers 710 to further improve the stability of the sliding cover body 100. Furthermore, a plurality of first travel assemblies 700 may be provided at intervals along the circumference of the sliding cover body 100 to ensure the balance of the sliding cover body 100. The first rollers 710 may be made of a soft material such as rubber or silicone to reduce wear and noise while also saving costs.

[0105] The animal feeding system also includes a second walking component 800, which includes a second roller 810. The second roller 810 is assembled on the housing 900 and can roll with the pressure member 600 to reduce the friction generated when the pressure member 600 moves relative to the housing 900.

[0106] With reference to the above, during the specific implementation, the pressure member 600 moves within the third accommodation space of the housing 900. This creates a certain gap between the outer wall of the pressure member 600 and the inner wall of the third accommodation space. This may cause the pressure member 600 to wobble during vertical movement and fail to accurately abut the support portion of the can body 1000. Consequently, the pressure member 600 cannot limit the can body 1000, and the food container cannot be opened. This embodiment provides a second travel assembly 800 between the pressure member 600 and the housing 900 to limit the horizontal displacement of the pressure member 600, ensuring smooth opening of the can body 1000.

[0107] Specifically, the second travel assembly 800 further includes a second mounting base 820, which is fixed to the side wall of the pressure member 600 via screws. A second roller 810 is mounted within the second mounting base, with the outer peripheral side wall of the second roller 810 contacting the inner wall of the housing 900. During the upward and downward movement of the pressure member 600, the second roller 810 rolls along the pressure member 600, reducing friction between the pressure member 600 and the housing 900. It also acts as a position limiter for the pressure member 600, thereby improving the stability of the upward and downward movement of the pressure member 600. It is understood that, as needed, the second mounting base 820 may be provided with multiple second rollers 810 to further improve the stability of the pressure member 600. Furthermore, multiple second travel assemblies 800 may be spaced apart along the circumference of the pressure member 600 to ensure the balance of the pressure member 600. The second rollers 810 may be made of a soft material such as rubber or silicone to reduce wear and noise, while also saving costs.

[0108] Optionally, the animal feeding system also includes a third detection component 920, which includes a third signal transmitter 921 and two third signal receivers 922. The third signal transmitter 921 is fixedly connected to the tank pressing device 10, and the third signal receiver 922 is fixedly connected to the housing 900. In the third position, one of the two third signal receivers 922 is set corresponding to the third signal receiver 922, and in the fourth position, the other of the two third signal receivers 922 is set corresponding to the third signal receiver 922.

[0109] The third detection assembly 920 cooperates with the third drive assembly 500 to control the movement of the pressure member 600. Specifically, a third signal transmitter 921 can be disposed on the second rack 530 and move with the second rack 530, or the second rack 530 can serve as the third signal transmitter 921. Two third signal receivers 922 are disposed on the housing 900, with a distance between them corresponding to the movement distance of the pressure member 600. In this embodiment, when the pressure member 600 reaches the fourth position, the rack is positioned between the two third signal receivers 922. The pressure member 600 moves upward, causing the top end of the rack to contact one of the third signal receivers 922. This triggers the third signal receiver 922 and generates a third detection signal to determine the position of the pressure member 600. Similarly, when the pressure member 600 reaches the third position and the bottom end of the rack contacts the other third signal receiver 922, the other third signal receiver 922 is triggered, causing the third motor 510 to stop and generate a third detection signal to determine the position of the pressure member 600.

[0110] In the specific implementation process, the third detection component 920 is a photoelectric sensor, the third signal transmitter 921 is a photoelectric transmitter, and the third signal receiver 922 is a photoelectric receiver; or, the third detection component 920 is a magnetic field sensor, the third signal transmitter 921 is a magnetic signal transmitter, and the third signal receiver 922 is a magnetic signal receiver; or, the third detection group is a mechanical switch, the third signal transmitter 921 is a mechanical protrusion, and the third signal receiver 922 is a mechanical button. This embodiment will not be described in detail.

[0111] In an embodiment of the present application, as shown in Figures 10 to 16, the food container comprises: a can body 1000 and a lid 2000, and the can body 1000 and the lid 2000 are snap-fitted together to facilitate opening and closing the lid 2000. The can body 1000 comprises a container body 1100 and a support member 1200. The container body 1100 comprises a container bowl 1110, which has a receiving cavity for holding food and an upwardly open opening communicating with the receiving cavity. The support member 1200 comprises a first flange portion 1210, one end of the first flange portion 1210 being connected to the outer peripheral wall of the container bowl portion 1110, and the other end of the first flange portion 1210 extending outwardly in a direction away from the container body 1100.

[0112] During the specific implementation process, the horizontal projection of the opening of the accommodating cavity can be a circle, square or other irregular shape, which is not limited in this embodiment. It can be understood that the accommodating cavity is used to hold food. In practice, the food can be dry food or moist food. In some embodiments, in order to ensure the sealing of the accommodating cavity, the cover 2000 covers the accommodating cavity of the container bowl 1110, so that the accommodating cavity has a certain sealing property, thereby ensuring the quality of the food. After the cover 2000 leaves the tank body 1000, the opening is exposed to the outside world, and the pet eats the food in the accommodating cavity from the opening. In other embodiments, the cover 2000 covers the accommodating cavity of the container bowl 1110, so that the accommodating cavity has a certain sealing property, thereby preventing the outflow of food odor or preventing the entry of insects.

[0113] As shown in Figures 13 and 14 , the support member 1200 is fixedly mounted on the outer peripheral wall of the container bowl 1110. One end of the first flange portion 1210 is connected to the container bowl 1110. The connection between the support member 1200 and the container bowl 1110 can be adhesively fixed, or the support member 1200 can be locked and fixed to the outer peripheral wall of the container bowl 1110 using a connector such as a screw or pin. In this embodiment, the support member 1200 is adhesively bonded to the container body, i.e., glue is applied between the two to ensure a tight bonded connection. In a specific implementation, the support member 1200 is used to abut against the animal feeding system when opening the food container. Specifically, the other end of the support member 1200 extends beyond the outer peripheral wall of the container body 1100, so that the portion between the one end and the other end of the support member 1200 extends beyond the outer peripheral wall of the support member 1200, facilitating the abutment of the animal feeding system against the support member 1200 when opening the food container. During the specific implementation process, in the projection of the food container on the horizontal plane, the outer edge of the first flange portion 1210 protrudes from the outer peripheral surface of the cover body 2000, avoiding interference from the container bowl portion 1110, so that when the animal feeding system pulls to open the cover body 2000, the movement of the tank body 1000 is restricted by abutting the support member 1200, making it convenient for the animal feeding system to drive the cover body 2000 away from the tank body 1000 and open the food container for the pet to eat.

[0114] Referring to Figures 16 and 17, the cover body 2000 includes a cover tray portion 2200 connected to the inner circumferential wall of the side wall portion 2100, the cover tray portion 2200 divides the cover body 2000 into a recessed space with an opening open upward and a lower space with an opening open downward, the cover flange portion 2300 is arranged in the recessed space, one end of the cover flange portion 2300 is connected to the side wall portion 2100, and the other end of the cover flange portion 2300 extends inward in a direction away from the cover body 2000, the cover flange portion 2300 and the side wall portion 2100 and the cover tray portion 2200 enclose a groove 2400; when the cover body 2000 is assembled on the can body 1000, the container bowl portion 1110 is snap-fitted with the side wall portion 2100.

[0115] In a specific implementation, as shown in FIG12 , when the cover 2000 is assembled on the can body 1000, the container body 1100 and the cover 2000 engage with each other, facilitating the opening and closing of the cover 2000. The container body 1100 and the cover 2000 may be engaged with each other by means of a snap fit, or by providing mutually cooperating protrusions, with the two protrusions acting as a locking limiter for each other.

[0116] Optionally, the support member 1200 and the container body 1100 are not integrally formed. It is understood that the support member 1200 is fixedly connected to the container body 1100 so that the animal feeding system abuts against the support member 1200 to limit the movement of the container body 1100. In the specific implementation process, on the one hand, the production of the container body 1100 and the support member 1200 are separate. The container body 1100 has a separate mold, and the support member 1200 also has a separate mold, which can simplify the design and manufacture of the molds. On the other hand, the container bowl 1110 of the container body 1100 is used to hold food, and thus the material control of the container body 1100 is relatively strict, meeting the hygiene requirements of pet food. However, the support member 1200 does not contact food and can be made from a variety of materials, which can leave more room for industrial implementation.

[0117] The cover body 2000 is snap-connected to the container body 1100. Optionally, in one embodiment, the container body 1100 further includes a second flange portion 1120, one end of the second flange portion 1120 is connected to the container bowl portion 1110, and the other end of the second flange portion 1120 extends outward in a direction away from the container body 1100. In the projection of the food container in the horizontal plane, the outer edge of the second flange portion 1120 protrudes from the outer peripheral surface of the container bowl portion 1110. The cover body 2000 further includes a third flange portion 2600, one end of the third flange portion 2600 is connected to the side wall portion 2100, and the other end of the third flange portion 2600 extends inward in a direction away from the cover body 2000. When the cover body 2000 is assembled on the can body 1000, the third flange portion 2600 is snap-fitted with the second flange portion 1120.

[0118] In a specific implementation, the second flange portion 1120 is disposed around the sidewall of the container body 1100. In this embodiment, the second flange portion 1120 conforms to the contour of the outer peripheral wall of the container body 1100. Specifically, the second flange portion 1120 is annular and disposed around the edge of the container body 1100 near the opening. The inner edge of the annular second flange portion 1120 is connected to the outer peripheral sidewall of the container bowl 1110, and the outer edge of the second flange portion protrudes from the outer peripheral surface of the container bowl 1110. In this way, the second flange portion extends horizontally and away from the container bowl 1110. It will be understood that the second flange portion 1120 can serve as a flange structure at the upper end of the container bowl 1110. Furthermore, the second flange portion 1120 constitutes the upper peripheral edge of the container body 1100. In practice, the second flange portion 1120 is integrally provided with the container bowl portion 1110 , thereby improving the overall strength and also improving the connection strength between the cover body 2000 and the can body 1000 .

[0119] Optionally, in another embodiment, the support member 1200 further includes a fourth flange portion 1220, which constitutes the upper periphery of the support member 1200. In the projection of the food container in the horizontal plane, the outer edge of the fourth flange portion 1220 protrudes from the outer peripheral surface of the container bowl portion 1110; the cover body 2000 further includes a third flange portion 2600, one end of the third flange portion 2600 is connected to the side wall portion 2100, and the other end of the third flange portion 2600 extends inward in a direction away from the cover body 2000; when the cover body 2000 is assembled on the tank body 1000, the fourth flange portion 1220 is snap-fitted with the third flange portion 2600.

[0120] As shown in Figure 13 , the fourth flange portion 1220 and the first flange portion 1210 are respectively located at the upper and lower ends of the support member 1200. The fourth flange portion 1220 constitutes the upper periphery of the support member 1200, and the first flange portion constitutes the lower periphery of the support member 1200. One inner end of the fourth flange portion 1220 is close to the container bowl portion 1110, while the other end extends away from the container bowl portion 1110. This allows the outer edge of the fourth flange portion 1220 to protrude from the outer circumference of the container bowl portion 1110, thereby facilitating the snap connection between the third flange portion 2600 and the fourth flange portion 1220 and avoiding interference with the container bowl portion 1110.

[0121] In this embodiment, the container body 1100 also includes a second flange portion 1120, one end of the second flange portion 1120 is connected to the container bowl portion 1110, and the other end of the second flange portion 1120 extends outward in a direction away from the container body 1100. The upper surface of the fourth flange portion 1220 is connected to the lower surface of the second flange portion 1120. In the projection of the food container in the horizontal plane, the outer edge of the fourth flange portion 1220 protrudes from the outer peripheral surface of the second flange portion 1120.

[0122] Specifically, it should be noted that one end of the second flange portion 1120 is a sidewall of the second flange portion 1120 that is adjacent to the accommodating cavity. It is connected to the outer circumference of the container bowl 1110 and extends circumferentially around the container bowl 1110. The other end of the second flange portion 1120 extends away from the container bowl 1110, extending beyond the container bowl 1110. In practice, it is understood that the second flange portion 1120 can serve as a flanged edge at the upper end of the container bowl 1110. The second flange portion 1120 is integrally formed with the container bowl 1110, thereby enhancing overall strength and the connection between the lid 2000 and the can body 1000. Furthermore, the outer edge of the fourth flange portion 1220 protrudes beyond the outer circumference of the second flange portion 1120, facilitating snap-fit ​​connection with the lid 2000 and protecting the second flange portion 1120.

[0123] Optionally, the cover 2000 further includes a lid tray portion 2200 connected to the inner circumferential wall of the sidewall portion 2100. The lid tray portion 2200 divides the cover 2000 into a recessed space with an upward opening and a lower space with a downward opening. A lid flange portion 2300 is disposed in the recessed space. The lid flange portion 2300, the sidewall portion 2100, and the lid tray portion 2200 enclose a groove 2400. When an animal feeding system including a food container is connected to the cover 2000, the animal feeding system engages with the groove 2400. In this embodiment, the groove 2400 is an annular groove.

[0124] In a specific implementation, the shape of the lid tray portion 2200 is adapted to the opening of the accommodating cavity. When the lid 2000 is assembled on the tank body 1000, the lid tray portion 2200 seals the opening. The sidewall portion 2100 is arranged along the sidewall edge of the lid tray portion 2200 and surrounds the lid tray portion 2200. The upper and lower ends of the sidewall portion 2100 are respectively located on either side of the lid tray portion 2200, thereby forming a recessed space on one side of the lid tray portion 2200 and a lower space on the other side. The upper portion of the recessed space has an opening to facilitate the connection of an external animal feeding system to the lid 2000 so that the lid 2000 can be removed from the tank body 1000. The lower portion of the lower space has an opening, and the top portion of the tank body 1000 is accommodated in the lower space through the opening. The edge of the lid flange 2300 connects to the top edge of the sidewall 2100 and extends toward the axis of the lid 2000. The lid flange 2300, the sidewall 2100 located on one side of the recessed space, and the lid tray 2200 surround a recess 2400, with the lid flange 2300 forming the upper perimeter of the lid 2000. The external animal feeding system extends into the recess 2400 and engages with the lid 2000. Further upward movement of the lid 2000 moves the lid 2000 away from the can body 1000, thereby opening the food container. It should be noted that, to ensure effective engagement of the external animal feeding system with the lid 2000, the lid flange 2300 extends radially along the lid 2000, positioning the lid flange 2300 horizontally. Specifically, the lid flange 2300 is positioned horizontally, facing the bottom wall of the recess 2400, to enhance the stability of the engagement.

[0125] Furthermore, based on the above, in this embodiment, the second flange portion 1120 forms the upper periphery of the container body 1100. When the lid 2000 is assembled on the can body 1000, the inner edge of the lid flange portion 2300 does not protrude beyond the inner surface of the second flange portion 1120 in the horizontal projection of the food container. This design, when the width of the engaging portion of the groove 2400 is constant, makes stacking multiple lids 2000 more stable compared to other solutions (e.g., where the inner edge of the lid flange portion 2300 protrudes beyond the inner surface of the second flange portion 1120), thereby facilitating factory transportation and assembly. Multiple lids 2000 stacked together are shown in Figure 18.

[0126] Furthermore, it is understood that bacteria and moisture in the air can affect the food within the container bowl 1110, causing it to spoil easily. Therefore, it is necessary to seal the receiving cavity of the container bowl 1110 to extend the shelf life of the food. Optionally, in this embodiment, as shown in Figures 11 and 16 , the food container further includes a sealing film 3000 for sealing the receiving cavity. A portion of the sealing film 3000 is connected to the lid tray 2200, while another portion of the sealing film 3000 is at least partially connected to the container bowl 1110. This seals the receiving cavity while also being connected to the lid tray 2200. Consequently, when the lid 2000 is driven away from the can body 1000, the sealing film 3000 simultaneously separates from the container bowl 1110, exposing the food without the need to open the sealing film 3000 again. Furthermore, the sealing film 3000 can be connected by adhesive bonding or hot melt bonding, depending on actual needs and the material of the sealing film 3000. In a specific implementation process, in order to ensure that the sealing film 3000 has a certain strength and avoids damage, the sealing film 3000 is made of aluminum film.

[0127] The lid tray portion 2200 is provided with a first through-hole 2210. The sealing film 3000 includes a main body of the sealing film 3000 and a connecting ear portion 3200 extending outward from the outer periphery of the main body of the sealing film 3000. The main body of the sealing film 3000 is connected to the upper surface of the container bowl portion 1110. The connecting ear portion 3200 passes through the first through-hole 2210 and enters the recessed space, where it is connected to the upper surface of the lid tray portion 2200. In a specific implementation, the connecting ear portion 3200 is integrally formed with the main body of the sealing film 3000 to enhance its strength. As will be appreciated, the portion of the sealing membrane 3000 body near the edge is connected to the top surface of the container bowl 1110. To ensure that the lid 2000 can smoothly drive the sealing membrane 3000 in synchronous movement, the connecting ear 3200 is connected to the edge of the sealing membrane 3000 body. This allows the force of the lid 2000 to act directly on the edge of the sealing membrane 3000 body, further releasing the connection between the sealing membrane 3000 body and the container bowl 1110. A first through-hole 2210 is defined near the edge of the lid tray 2200. The end of the connecting ear 3200, facing away from the sealing membrane 3000 body, passes through the first through-hole 2210 and enters the recessed space. One surface of the connecting ear 3200 is connected to the surface of the lid tray 2200 facing the recessed space. The connecting ear 3200 allows the tensile force of the lid 2000 to be applied directly to the connection between the sealing membrane 3000 body and the container bowl 1110, making release of the two more labor-efficient. Furthermore, in order to ensure balance and effectively separate the sealing film 3000 body from the container bowl 1110, in a specific implementation process, the sealing film 3000 body is provided with at least two groups of connecting ears 3200, which are symmetrically arranged.

[0128] Referring to Figures 19 to 22, another embodiment of the food container of the present application includes a sealing film 3000 comprising a sealing film body 3100 and a connecting ear 3200 extending outward from the outer periphery of the sealing film body 3100. The sealing film body 3100 is connected to the upper surface of the container bowl 1110. The connecting ear 3200 is folded upward and inward to connect to the lower surface of the lid tray 2200. It is understood that the portion of the sealing film body 3100 near the edge is connected to the top surface of the container bowl 1110. To ensure that the lid 2000 can smoothly drive the sealing film 3000, the connecting ear 3200 is connected to the edge of the sealing film body 3100. The connecting ear 3200 is folded upward and inward to connect to the lid 2000. This allows the force of the lid 2000 to be transmitted to the edge of the sealing film body 3100 through the connecting ear 3200, thereby further releasing the connection between the sealing film body 3100 and the container bowl 1110.

[0129] In these embodiments, as shown in FIG22 , the connecting ear 3200 includes a first adhesive section 3210 and a second adhesive section 3220 connected to each other. The first adhesive section 3210 is closer to the outer periphery of the sealing film body 3100 than the second adhesive section 3220. The sealing film 3000 includes two connecting ears 3200. The first adhesive section 3210 of one of the two connecting ears 3200 is connected to the lower surface of the lid tray portion 2200, and the second adhesive section 3220 of the other of the two connecting ears 3200 is connected to the lower surface of the lid tray portion 2200. It will be appreciated that when the lid body 2000 moves upward, the two connecting ears 3200 of the sealing film 3000 are subjected to forces of different magnitudes, which helps maintain the structural stability of the food container.

[0130] To ensure that the sealing film body 3100 is effectively separated from the container bowl 1110 , in a specific implementation process, the sealing film 3000 includes a plurality of connecting ears 3200 , and the plurality of connecting ears 3200 are axially symmetrically arranged about the central axis of the sealing film 3000 .

[0131] As shown in Figure 22, when the sealing film 3000 is assembled on the can body 1000 and the cover body 2000, in the projection of the food container in the horizontal plane, the outer edge of the sealing film 3000 (such as the folded part of the connecting ear 3200 when the second bonding section 3220 of the connecting ear 3200 is connected to the lower surface of the cover tray part 2200) will protrude from the outer peripheral surface of the container body 1100, and the cover body 2000 will cover and accommodate the outer part of the sealing film 3000 protruding from the outer peripheral surface of the container body 1100.

[0132] Furthermore, the cover body 2000 also includes a handle portion 2500, which is arranged in the recessed space. The handle portion 2500 is connected to the cover tray portion 2200. In the axial direction of the central axis of the cover body 2000, the upper surface of the handle portion 2500 is lower than the cover flange portion 2300. The cover tray portion 2200 is provided with a second through hole 2220. The handle portion 2500 is arranged above the second through hole 2220. The food container is in the projection of the horizontal plane, and the second through hole 2220 is located at the center of the cover body 2000.

[0133] The handle 2500 is used for carrying, facilitating lifting the lid 2000. To enhance its strength, the handle 2500 is integrally formed with the lid tray 2200. In practice, the handle 2500 is a curved strip structure, connected to the lid tray 2200 at each end. The ends extend in an arc toward the center, resulting in the center of the handle 2500 protruding upward and higher than the ends. This creates a space between the handle 2500 and the lid tray 2200, making it easier to insert a hand into the space between the handle 2500 and the lid tray 2200, thereby lifting the handle 2500. Furthermore, the lid tray 2200 is provided with a second through-hole 2220, with the handle 2500 positioned above the second through-hole 2220. Specifically, the handle portion 2500 is disposed across the second through hole 2220 to increase the space below the handle portion 2500 , making it easier to insert a hand to pull the cover 2000 .

[0134] Optionally, the side wall of the container bowl 1110 includes a first section 1111, a second section 1112 and a third section 1113, and the extension direction of the second section 1112 is perpendicular to the central axis of the container body 1100, so that the second section 1112 has a first circumferential wall and a second circumferential wall, and the second circumferential wall is arranged at one end of the second section 1112 close to the central axis of the container body 1100, the first section 1111 extends upward from the first circumferential wall of the second section 1112 to an opening connected to the accommodating cavity, and the third section 1113 extends downward from the second circumferential wall of the second section 1112 to the bottom wall of the container bowl 1110, and the support body includes a step portion 1230, the upper part of the step portion 1230 is connected to the first section 1111, the platform part of the step portion 1230 is connected to the second section 1112, and the lower part of the step portion 1230 is connected to the third section 1113.

[0135] As shown in FIG14 , in a specific embodiment, the second section 1112 extends horizontally. The end of the second section 1112 near the central axis of the container bowl 1110 forms a second peripheral wall. The first peripheral wall and the second peripheral wall are disposed opposite each other. Specifically, one end of the first section 1111 is connected to the first peripheral wall and extends upward to the opening of the accommodating cavity. One end of the third section 1113 is connected to the second peripheral wall and extends downward to the bottom wall of the container bowl 1110. Thus, the first section 1111, the second section 1112, and the third section 1113 form the sidewall of the container bowl 1110. A stepped structure is formed at the second section 1112, which cooperates with the stepped portion 1230 of the support body. This allows the support body, i.e., the stepped portion 1230 and the upward and downward extending portions of the stepped portion 1230, to respectively cooperate and connect with the sidewall of the container bowl 1110, thereby improving the connection strength between the support member 1200 and the container bowl 1110.

[0136] In practice, the food container is placed in the animal feeding system and the cover 2000 is automatically opened. It can be understood that there is a space or groove for placing the food container in the animal feeding system. The animal feeding system needs to cooperate with the cover 2000 and the tank body 1000 respectively so that the cover 2000 leaves the tank body 1000. There are certain positioning requirements for the placement of the food container, so that the food container is placed in the corresponding position each time to ensure cooperation with the animal feeding system. This embodiment achieves the positioning requirements of the food container by providing a positioning portion 1240 on the support member 1200.
