Description

Food containers and pet feeders Technical Field

[0001] The present application relates to the field of animal feeding technology, and in particular to a food container and a pet feeder. Background Art

[0002] Existing pet food containers typically require the pet's owner to manually open them when the pet needs to eat. Opening the pet food container relies on human intervention, and without human intervention, the pet cannot open the food container on its own. This can be problematic when the pet owner is away from home and the pet is unable to open the food container on its own. If the pet relies on canned wet food for their diet, being left alone for extended periods of time may result in the pet being unable to access food.

[0003] Application Contents

[0004] The purpose of this application is to solve at least one of the above technical deficiencies.

[0005] To this end, the present application provides a pet feeder, which provides a convenient and reliable way for pets to obtain wet food.

[0006] In order to achieve the above-mentioned object, the pet feeder is used for a food container, and the food container includes a tank body and a sealing film for sealing the tank body. The present application provides a pet feeder, and the pet feeder includes:

[0007] A material transport mechanism, the material transport mechanism comprising a material tray drive assembly and a material tray in transmission connection, the material tray being provided with a receiving area for receiving the food containers, the material tray drive assembly being used to drive the material tray to rotate so that the receiving area has a can opening station and a can sealing station;

[0008] a food container opening mechanism, the food container opening mechanism being provided corresponding to the can opening station and configured to cut the sealing film into a separated portion and a residual portion connected to the can body;

[0009] A food container sealing mechanism is provided corresponding to the can sealing station and is used for sealingly connecting a cover capable of sealing the can body to the can body.

[0010] In the above technical solution of the present application, when the pet needs to eat, the material tray driving assembly drives the material tray to rotate so that the food container located in the accommodating area is moved to the can opening station. Since the food container opening mechanism is arranged corresponding to the can opening station, the sealing film of the sealed can body can be cut into a residual part and a separation part by the food container opening mechanism. The residual part is connected to the can body, and the separation part is separated from the residual part to form an opening for the pet to eat, thereby realizing automatic opening of the food container for the pet without human intervention; after the pet has eaten the food container, if it is not handled in time, the food container after eating will produce an odor and even attract mosquitoes. Therefore, after the pet has eaten the food container, the material tray driving assembly drives the material tray to rotate so that the food container is moved to the can sealing station, and the food container sealing mechanism is arranged to cover the opening of the can body and seal the can body, thereby effectively preventing the food container from producing an odor after eating.

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] It should be noted that all directional indications (such as up, down, etc.) in the implementation manner of this application are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in Figure 1).

Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of these features.

[0043] Moreover, the technical solutions between the various implementation methods of the present application can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] The present application provides a pet feeder 1. In one embodiment, as shown in Figures 1 to 17, the pet feeder 1 is used for a food container 2. The food container 2 includes a can body 22 and a sealing film 23 that seals the can body 22. The pet feeder 1 includes a material transport mechanism 11, a food container opening mechanism 12, and a food container sealing mechanism 14. The material transport mechanism 11 includes a feed tray driving assembly 111 and a material tray 112 that are transmission-connected. The material tray 112 is provided with a receiving area for receiving the food container 2. The feed tray driving assembly 111 is used to drive the material tray 112 to rotate so that the receiving area has a can opening station 1121 and a can sealing station 1122; the food container opening mechanism 12 is provided corresponding to the can opening station 1121, and is used to cut the sealing film 23 into a separation portion 232 and a residual portion 231 connected to the can body 22; the food container sealing mechanism 14 is provided corresponding to the can sealing station 1122, and is used to seal the cover 21 that can seal the can body 22 with the can body 22.

[0045] Among them, when the pet needs to eat, the feed tray driving component 111 drives the material tray 112 to rotate, so that the food container 2 located in the accommodating area moves to the can opening station 1121. Since the food container opening mechanism 12 is corresponding to the can opening station 1121, the sealing film 23 of the sealed can body 22 can be cut into a residual portion 231 and a separation portion 232 by the food container opening mechanism 12. The residual portion 231 is connected to the can body 22, and the separation portion 232 is separated from the residual portion 231 to form an opening for the pet to eat, thereby realizing the opening of the can body 22 when there is no personnel. With the participation of the pet, the food container 2 is automatically opened for the pet; after the pet has eaten the food container 2, if it is not handled in time, the food container 2 will produce an odor and even attract mosquitoes. Therefore, after the pet has eaten the food container 2, the material tray driving assembly 111 drives the material tray 112 to rotate, so that the food container 2 is moved to the can sealing station 1122, and the food container closing mechanism 14 is set to cover the cover 21 at the opening of the can body 22 and seal the can body 22, thereby effectively preventing the food container 2 from producing an odor after eating.

[0046] The lid 21 is then driven by the food tray driving assembly 111 to rotate, so that the food container 2 is moved to the capping station, and the lid 21 on the can body 22 is removed and retained. The material tray 112 is then driven to rotate by the food tray driving assembly 111, and the sealing film 23 is cut by the food container opening mechanism 12. After the pet has finished eating the food container 2, the material tray 112 is driven to rotate by the food tray driving assembly 111 to move the food container 2 to the can sealing station 1122, and the previously retained lid 21 is then covered on the can body 22 by the food container closing mechanism 14, thereby realizing the opening and closing of the food container 2. Among them, the cover body 21 of the food container closing mechanism 14 that is covered on the can body 22 can be a cover body 21 that originally matches the can body 22, or when the food container 2 itself does not have a cover body 21, the food container closing mechanism 14 closes the can body 22 through the cover body 21 that can match the can body 22.

[0047] In one embodiment, a first limiting portion 1126 is provided at the accommodating area, and the first limiting portion 1126 is used to abut against the can body 22 to limit the rotation of the can body 22. The food container closing mechanism 14 includes a screw-on cover device and a first lifting device 12120: the screw-on cover device includes a first driving assembly 1211 and a screw-on cover assembly 1212, the screw-on cover assembly 1212 includes a screw-on cover member 12121, the first driving assembly 1211 is transmission-connected to the screw-on cover member 12121, and the screw-on cover member 12121 is provided with a second limiting portion 121211, and the second limiting portion 121211 is used to cooperate with the cover body 21 to drive the cover body 21 to rotate; the first lifting device 12120 is transmission-connected to the first driving assembly 1211, and the first lifting device 12120 drives the screw-on cover device to move in the up and down directions, and the screw-on cover device is used to drive the cover body 21 to rotate toward or away from the can body 22. When it is necessary to remove the cover 21 from the tank body 22, the first lifting device 12120 drives the rotary cover member 12121, which is transmission-connected to the first driving assembly 1211, to move toward the direction close to the food container 2 through the first driving assembly 1211. The second limiting portion 121211 on the rotary cover member 12121 can cooperate with the limit of the cover 21 of the food container 2 located on the material tray 112. The rotary cover member 12121 is driven to rotate by the first driving assembly 1211. Since the tank body 22 of the food container 2 abuts against the first limiting portion 1126 on the material tray 112, the first limiting portion 1126 can limit the rotation of the tank body 22 relative to the material tray 112 to disengage the cover body 21 from the tank body 22, thereby realizing the automatic opening of the food container 2 by relying on the food container closing mechanism 14 without the participation of personnel.

[0048] It should be noted that the first limiting portion 1126 can be a magnetic component, which can absorb the tank body 22 in contact with it, thereby limiting the rotation of the tank body 22 relative to the material tray 112; or the first limiting portion 1126 can be a lock, which can lock the first limiting portion 1126 through the lock to limit the rotation of the tank body 22 relative to the material tray 112.

[0049] It should also be noted that those skilled in the art will know that the cover body 21 and the tank body 22 are connected by a rotational fit, and the cover body 21 rotates relative to the tank body 22 to release the threaded fit relationship. After the threaded fit relationship is released, the cover body 21 is detached from the tank body 22.

[0050] In this embodiment, the cover 21 and the tank body 22 are threadedly engaged; in other embodiments, the cover 21 and the tank body 22 are rotationally snap-fitted.

[0051] According to one embodiment of the present application, the screw-on cover 12121 can be a magnetic part that absorbs the cover body 21. When the cover body 21 needs to be sealed and connected to the tank body 22, the first lifting device 12120 drives the screw-on cover 12121 to move toward the tank body 22 through the first driving component 1211 until it is released from the tank body 22. The screw-on cover 12121 is driven to rotate by the first driving component 1211, thereby restoring the threaded fit between the cover body 21 and the tank body 22, thereby realizing automatic sealing of the food container 2 by relying on the food container closing mechanism 14 without human intervention.

[0052] In one embodiment, the first driving component 1211 includes a first driving member 12111 and a first transmission member 12112 that are connected to each other, the rotary cover member 12121 slides with the first transmission member 12112, the rotary cover member 12121 can move in the up and down directions relative to the first transmission member 12112 and has a first position and a second position. In the first position, the second limiting portion 121211 is used to limit the cooperation with the cover body 21, and in the second position, the second limiting portion 121211 is used to disengage from the cover body 21; the rotary cover assembly 1212 also includes a first restoring member 12102, one end of the first restoring member 12102 is connected to the rotary cover member 12121, and the other end of the first restoring member 12102 is connected to the first transmission member 12112, and the first restoring member 12102 applies an elastic restoring force to the rotary cover member 12121 to move from the second position to the first position.

[0053] In the solution of this embodiment, the first lifting device 12120 drives the rotary cover member 12121, which is transmission-connected to the first driving component 1211, through the first driving component 1211 to move downward close to the can 2 so that the rotary cover member 12121 contacts the cover body 21. At this time, the second limiting portion 121211 on the rotary cover member 12121 may be limitedly matched with the cover body 21 located on the material tray 112. It is also possible that the second limiting portion 121211 of the rotary cover member 12121 is not limitedly matched with the cover body 21 located on the material tray 112. In this case, when the first driving component 1211 drives the rotary cover member 12121 to rotate, the rotary cover member 12121 slides with the first transmission member 12112. At this time, the rotary cover member 12121 moves downward and is limitedly matched with the cover body 21 located on the material tray 112.

[0054] Moreover, in the above technical solution, since the rotary cover member 12121 and the first transmission member 12112 can slide and cooperate in the up and down directions, the first transmission member 12112 does not need to rise in conjunction with the continuously rising position of the cover body 21 during the process of the rotary cover member 12121 driving the cover body 21 to rotate, because the rotary cover member 12121 will slide upward relative to the first transmission member 12112 as the cover body 21 rises.

[0055] When the first lifting device 12120 drives the first transmission member 12112 to descend to the third stroke, the second limiting portion 121211 fails to cooperate with the cover body 21, and the second limiting portion 121211 will be lifted up by the cover body 21 and slide upward relative to the first transmission member 12112. At this time, the first driving member 12111 is required to drive the rotary cover member 12121 to rotate a preset angle. During the rotation of the rotary cover member 12121, if the rotary cover member 12121 is able to complete the limiting cooperation with the cover body 21 after the second limiting portion 121211 descends at a certain position, then when the rotary cover member 12121 rotates to this position, the first restoring member 12102 can quickly drive the rotary cover member 12121 to move downward, so that the second limiting portion 121211 completes the limiting cooperation with the cover body 21. It should be noted that the first restoring member 12102 can be a spring.

[0056] In one embodiment, the rotary cover assembly 1212 further includes a limit member 12123, which is movably provided on the first transmission member 12112. The limit member 12123 is connected to the rotary cover member 12121. When the rotary cover member 12121 moves downward by a first stroke, the limit member 12123 abuts against the first transmission member 12112. In this embodiment, the limit member 12123 is connected to the rotary cover member 12121. When the rotary cover member 12121 moves downward by a first stroke from the first position relative to the first transmission member 12112, the limit member 12123 abuts against the transmission member, thereby limiting the rotary cover member 12121 from continuing to descend, thereby preventing the rotary cover member 12121 from being separated from the first transmission member 12112 due to the action of gravity, resulting in failure of the sliding fit.

[0057] As shown in Figure 5, the first transmission member 12112 is provided with a first installation channel 121121 that runs through the upper and lower parts. The rotary cover member 12121 includes a rotary cover body and a sliding portion 12212 that are connected to each other. The rotary cover body is provided with a second limiting portion 121211. The sliding portion 12212 is provided in the first installation channel 121121 and slides with the first installation channel 121121. In this embodiment, by setting the sliding portion 12212 to slide with the first installation channel 121121, the first installation channel 121121 can limit the rotary cover body, that is, limit the movement of the rotary cover body along the radial direction of the first installation channel 121121.

[0058] As shown in Figure 5, the first drive assembly 1211 also includes a first bracket 12113, the first drive member 12111 is installed on the first bracket 12113, the first lifting device 12120 includes a second drive member 121201 and a second transmission member 12122 that are transmission-connected, the second transmission member 12122 is provided with a lifting portion 12128, the lifting portion 12128 is rollingly engaged with the first bracket 12113, the second drive member 121201 drives the second transmission member 12122 to move left and right, so that the lifting portion 12128 can drive the first bracket 12113 to move up and down. In this embodiment, the second driving member 121201 can drive the second transmission member 12122 to move back and forth in the left and right directions. By setting the lifting part 12128, when the second driving member 121201 drives the second transmission member 12122 to move to the left, the lifting part 12128 can guide the first bracket 12113 to move upward; when the second driving member 121201 drives the second transmission member 12122 to move to the right, the lifting part 12128 can guide the first bracket 12113 to move downward, thereby converting the left and right movement of the second transmission member 12122 into the up and down movement of the first bracket 12113 through the lifting part 12128.

[0059] In one embodiment, the second transmission member 12122 includes a lifting body 12124 and a rack 12125 connected to each other. The lifting portion 12128 is provided on the lifting body 12124. The output shaft of the second driving member 121201 is provided with a gear 12126 for meshing with the rack 12125. This embodiment achieves transmission through the meshing of the gear 12126 and the rack 12125, thereby effectively improving transmission accuracy.

[0060] Those skilled in the art can easily think of realizing the reciprocating movement of the second transmission member 12122 through a screw assembly, that is, the output shaft of the second driving member 121201 is connected to the screw of the screw assembly, and the lifting part 12128 is connected to the slider of the screw assembly, which can also realize the reciprocating movement of the second transmission member 12122.

[0061] Moreover, in one embodiment, the height of the lifting portion 12128 is arranged to increase along the extension direction of the rack 12125, wherein the height of the lifting portion 12128 gradually increases along the extension direction of the rack 12125, so that the lifting movement can be smoother.

[0062] As shown in FIG4 , the lifting portion 12128 is formed with a slide groove 12127. The first bracket 12113 is connected to a rolling element 12114. At least a portion of the rolling element 12114 extends into the slide groove 12127 and rolls with the bottom wall 222 of the slide groove 12127. The rolling element 12114 may be a first rolling wheel. The rolling engagement of the first rolling wheel with the bottom wall 222 of the slideway results in less friction than the sliding engagement between the first bracket 12113 and the slide groove 12127.

[0063] As shown in Figures 4 and 5, the pet feeder 1 includes a second bracket 17, a second driving member 121201 mounted on the second bracket 17, and a second mounting channel 171 extending vertically therethrough. The first bracket 12113 is disposed within and slidably engages with the second mounting channel 171. The second transmission member 12122 slidably engages with the second bracket 17 or rolls with the second bracket 17. In this embodiment, the provision of the second mounting channel 171 allows the second mounting channel 171 to, while slidingly engaging with the first bracket 12113, also limit the position of the first bracket 12113, restricting movement of the first bracket 12113 relative to the second mounting channel 171 in a radial direction. The second transmission member 12122 can be directly slidably matched with the second bracket 17, or the second transmission member 12122 can be rolling matched with the second bracket 17, wherein the friction force exerted on the second transmission member 12122 in the rolling match is smaller than the friction force exerted on the second transmission member 12122 in the sliding match.

[0064] In one embodiment, the second bracket 17 is provided with a plurality of rollers 172, which are sequentially arranged along the moving direction of the second transmission member 12122. The rollers 172 are in rolling engagement with the second transmission member 12122. By providing a plurality of rollers 172, the reliability of the rollers 172 in supporting the second transmission member 12122 is ensured.

[0065] In one embodiment, the pet feeder 1 further comprises a claw assembly 13 connected to the first drive assembly 1211. The claw assembly 13 is configured to clamp or release the cover 21. The claw assembly 13 is hingedly connected to the first drive assembly 1211 and comprises a claw 131 and a second return member 132. The cover 21 has a clamping portion 211 detachably connected to the claw 131. The claw 131 is movable between a third position in which it engages with the clamping portion 211 and a fourth position in which it disengages from the clamping portion 211. The second return member 132 applies an elastic return force to the claw 131 to move it from the fourth position to the third position. In this embodiment, after the cover 21 is separated from the tank 22, the claw assembly 13 clamps the cover 21, and the lifting device drives the cover 21 upward via the claw assembly 13, allowing the cover 21 to move away from the tank 22. In this embodiment, the second restoring member 132 is provided to apply an elastic restoring force to the claw 131 to move it to the third position, so that the claw 131 is pressed against the engaging portion 211 , thereby improving the reliability of the engaging fit between the claw 131 and the engaging portion 211 .

[0066] As shown in Figures 4 and 12, in one embodiment, the pet feeder 1 further includes a third bracket 18, which is disposed on the outer periphery of the claw 131. The inner wall of the third bracket 18 is provided with a first inclined surface 181, which extends upward from the outside to the inside toward the first drive assembly 1211. When the first lifting device 12120 moves upward, the claw 131 cooperates with the first inclined surface 181 to guide the claw 131 from the third position to the fourth position. In this embodiment, when the claw 131 clamps the cover body 21, the first lifting device 12120 will drive the transmission member to rise, and the claw 131 will abut against the first inclined surface 181 and move from the third position to the fourth position under the guidance of the first inclined surface 181, so that the cover body 21 clamped by the claw 131 is separated from the claw 131; that is, in this solution, the clamping or releasing of the cover body 21 by the claw assembly 13 does not rely on the driving member that drives the claw 131 to move back and forth between the third position and the fourth position, so the cost is lower.

[0067] In one embodiment, when the first lifting device 12120 moves upward to the second stroke, the top of the claw 131 abuts against the first inclined surface 181; that is, the first lifting device 12120 needs to move upward to the second stroke to ensure the separation of the cover body 21 and the tank body 22, and the top of the claw 131 abuts against the first inclined surface 181 to avoid the movement of the tank body 22 interfering with the cover body 21.

[0068] As shown in Figure 12, the third bracket 18 is a protective housing, which is located around the outer periphery of the rotary cover assembly 1212. The first inclined surface 181 extends along the circumference of the protective housing, and the protective housing defines a third mounting channel 182 for the rotary cover assembly 1212 to pass through. The third bracket 18 is a protective housing that protects the components located within the protective housing.

[0069] In one embodiment, the claw 131 includes a hinged portion 1311 and a hook portion 1312 that are interconnected. The hinged portion 1311 is hinged to the first drive assembly 1211, and the side wall of the cover body 21 is provided with an annular groove, which is the clamping portion 211; in the third position, the hook portion 1312 at least partially extends into the annular groove and hooks the cover body 21; wherein the clamping portion 211 is an annular groove, so that the hook portion 1312 can more easily complete the clamping fit with the groove wall of the annular groove, that is, the hook portion 1312 can be clamped fit with the groove wall at any position on the circumference of the annular groove.

[0070] As shown in FIG4 , the bottom end of the claw 131 has a second inclined surface 1313. The second inclined surface 1313 extends upward from the outside to the inside toward the first drive assembly 1211. The second inclined surface 1313 cooperates with the cover 21 when the first lifting device 12120 moves downward to guide the claw 131 from the fourth position to the third position. In this embodiment, by providing the second inclined surface 1313 at the bottom end of the claw 131, when the lifting device drives the claw 131 downward, the claw 131 will not collide with the top of the cover 21, thereby preventing damage to the claw 131. The second inclined surface 1313 will drive the claw 131 to move from the third position to the fourth position until the hook portion 1312 separates from the cover 21. The claw 131 will then move to the third position under the action of the second reset member 132, thereby completing the engagement with the annular groove.

[0071] As shown in Figures 2 and 15, in one embodiment, the first limiting portion 1126 has a plurality of first latch teeth 11261, and the plurality of first latch teeth 11261 extend upward, and the first latch teeth 11261 are used to cooperate with the first latch groove 221 provided at the bottom of the tank body 22; wherein the first latch teeth 11261 cooperate with the first latch groove 221 to limit the first limiting portion 1126 can limit the rotation of the tank body 22 relative to the material tray 112.

[0072] As shown in FIG6 , the second position-limiting portion 121211 has a plurality of second latching teeth 121212, which are arranged sequentially along the circumference of the rotary cover member 12121. The plurality of second latching teeth 121212 extend outwardly, and the second latching teeth 121212 are configured to engage with a second latching groove 213 provided on the inner wall of the groove 212 provided on the top surface of the cover body 21. The top surface of the cover body 21 is provided with a groove 212, and the inner wall of the groove 212 is recessed to form the second latching groove 213. The second latching groove 213 engages with the second latching teeth 121212 to enable the second position-limiting portion 121211 to transmit torque to the cover body 21, thereby driving the cover body 21 to rotate relative to the tank body 22.

[0073] In one embodiment, the food container opening mechanism 12 comprises:

[0074] A second lifting device 141 includes a first lifting assembly 1411. The first lifting assembly 1411 includes a third driving member 14111 and a third transmission member 14112 that are transmission-connected. The third driving member 14111 is used to drive the third transmission member 14112 to move in the up and down directions.

[0075] The annular tool 142 is connected to the third transmission member 14112. The third transmission member 14112 drives the annular tool 142 to move so that the annular tool 142 has a fifth position and a sixth position. The annular tool 142 has a cutting portion 1423 for cutting the sealing film 23. The annular tool 142 is in the fifth position, and the cutting portion 1423 is used to abut against the sealing film 23. The annular tool 142 is in the sixth position, and the cutting portion 1423 is used to separate the residual portion 231 located on the outside of the annular tool 142 from the separation portion 232 located on the inside of the annular tool 142. When the pet needs to eat, the third driving member 14111 drives the third transmission member 14112 to descend. Since the annular cutter 142 is connected to the third transmission member 14112, the third driving member 14111 can drive the annular cutter 142 to descend to the fifth position through the third transmission member 14112. The bottom of the annular cutter 142 is provided with a cutting portion 1423. When the annular cutter 142 is in the fifth position, the cutting portion 1423 abuts against the sealing film 23, and the third driving member 14111 drives the annular cutter 142 to descend from the fifth position to the sixth position. The cutting portion 1423 cuts the sealing film 23 into a residual portion 231 located on the outside of the annular cutter 142 and a separating portion 232 located on the inside of the annular cutter 142, that is, the annular cutter 142 cuts the separating portion 232 off the original sealing film 23, and then the annular cutter 142 is driven upward by the third driving member 14111, so that the pet can easily remove the separating portion 232 and enjoy the food inside the tank body 22; thus, the food container 2 sealed by the sealing film 23 is opened through the pet feeder 1 without human intervention.

[0076] In one embodiment, the annular cutter 142 further includes a first support portion 1424 for supporting the separating portion 232. The second transmission member 12122 drives the annular cutter 142 to move so that the annular cutter 142 has a seventh position. When the annular cutter 142 is in the seventh position, the first support portion 1424 is configured to abut against the separating portion 232 to restrict the free fall of the separating portion 232. In this embodiment, the first support portion 1424 is configured to abut against the separating portion 232 when the annular cutter 142 is in the seventh position, providing reliable support for the separating portion 232 and preventing the separating portion 232 from falling due to gravity and separating from the first support portion 1424. When the annular cutter 142 is in the seventh position, the second driving member 121201 drives the annular cutter 142 upward via the second transmission member 12122, thereby driving the separating portion 232 to move away from the canister 22, thereby preventing the separating portion 232 from being accidentally ingested by the pet while eating. It should be noted that the sealing film 23 is an aluminum-plastic film or tin foil with a certain hardness.

[0077] In one embodiment, the second lifting device 141 further includes a second lifting assembly 1412, and the second lifting assembly 1412 includes a fourth driving member 14121 and a fourth transmission member 14122 that are transmission-connected. The fourth driving member 14121 is used to drive the fourth transmission member 14122 to move in the up and down directions so that the fourth transmission member 14122 abuts against or separates from the tank body 22; the fourth driving member 14121 is used to drive the fourth transmission member 14122 to move in the direction close to the tank body 22 so that the fourth transmission member 14122 can abut against the tank body 22, thereby avoiding After the annular cutter 142 cuts the sealing film 23, the third driving member 14111 drives the annular cutter 142 to rise through the third transmission member 14112, and the can body 22 is also driven to move upward. Because the fourth transmission member 14122 abuts against the can body 22, it will limit the upward movement of the can body 22. Therefore, the annular cutter 142 cannot drive the can body 22 to rise together after cutting the sealing film 23, thereby avoiding the can body 22 that rises together with the annular cutter 142 from falling and causing the food inside the can body 22 to spill.

[0078] As shown in Figures 7 and 10, the annular cutter 142 includes a cutter body 1421 and a plurality of cutting teeth 1422. The plurality of cutting teeth 1422 are provided on the bottom end surface of the cutter body 1421. The plurality of cutting teeth 1422 extend downwardly and are arranged in sequence along the extension direction of the cutter body 1421. The provision of the plurality of cutting teeth 1422 facilitates the complete separation of the separation portion 232 from the residual portion 231, thereby preventing the separation portion 232 and the residual portion 231 from remaining connected.

[0079] Furthermore, in one embodiment, the annular cutter 142 further includes a first protrusion 1424A, which is disposed on the inner circumferential wall of the cutter body 1421 or on the inner circumferential wall of the cutting teeth 1422. The first protrusion 1424A serves as a first support portion 1424. A plurality of first protrusions 1424A are arranged along the extension direction of the annular cutter 142, and the tops of the first protrusions 1424A are configured to abut against the separating portion 232. The first protrusions 1424A may be disposed on the inner wall of the cutter body 1421 and spaced apart along the circumference of the inner wall of the cutter body 1421, or may be disposed on the cutting teeth 1422 and spaced apart along the arrangement direction of the plurality of cutting teeth 1422. Those skilled in the art will appreciate that the first protrusions 1424A may be arc-shaped or hook-shaped.

[0080] Those skilled in the art will appreciate that, in a scheme where the first protrusion 1424A is provided on the cutting tooth 1422, the third position of the annular cutter 142 is provided between the first position of the annular cutter 142 and the second position of the annular cutter 142; or in a scheme where the first protrusion 1424A is provided on the inner wall of the cutter body 1421, the third position of the annular cutter 142 is provided below the second position of the annular cutter 142.

[0081] According to an embodiment of the present application, the plurality of first protrusions 1424A are divided into a first protrusion group 1424A and a second protrusion group 1425A. The first protrusion group 1424A and the second protrusion group 1425A both include a plurality of first protrusions 1424A sequentially spaced along the circumference of the annular tool. The first protrusion group 1424A and the second protrusion group 1425A are spaced along the axial direction of the annular tool 142, that is, the first protrusion group 1424A is a circle of first protrusions 1424A, and the second protrusion group 1425A is Regarding the other circle of first protrusions 1424A, the separating portion 232 generally first abuts against the first protrusions 1424A in the group of first protrusions 1424A disposed near the top. As the separating portion 232 rises with the annular cutter 142, even if the separating portion 232 falls relative to the annular cutter 142, the protrusions of the group of second protrusions 1425A can provide support for it, thereby preventing the separating portion 232 from separating from the annular cutter 142 and ensuring that the annular cutter 142 can smoothly remove the separating portion 232 from the can body 22. It should be noted that the first protrusions 1424A of the group of first protrusions 1424A can be disposed on the inner wall of the cutter body 1421, and the second protrusions 1425A of the group of second protrusions 1425A can be disposed on the inner wall of the cutting teeth 1422.

[0082] In one embodiment, the fourth transmission member 14122 defines a first chamber 14123 having a bottom opening, the third transmission member 14112 is at least partially disposed within the first chamber 14123, and the annular cutter 142 is capable of extending from the bottom opening of the first chamber 14123. Compared to a case where the third transmission member 14112 and the fourth transmission member 14122 are spaced apart, the provision of the first chamber 14123 within the fourth transmission member 14122, which is capable of accommodating at least a portion of the third transmission member 14112, effectively reduces the overall volume.

[0083] In addition, in one embodiment, the third transmission member 14112 defines a second chamber 14113 having a bottom opening, a first through hole 14124 is provided on the top wall of the first chamber 14123, and a second through hole 14114 is provided on the top wall of the second chamber 14113. The pet feeder 1 also includes: a separation assembly 30 and a fixing base 40, the separation assembly 30 includes a connecting member 31 and a separating member 32 connected to each other, and the separating member 32 is at least partially provided in the second chamber 14113; the fixing base 40 is fixed in relative position to the third driving member 14111, one end of the connecting member 31 is connected to the fixing base 40, and the other end of the connecting member 31 passes through the first through hole 14124 and the second through hole 14114 to connect to the separating member 32; the fourth transmission member 14122 and the third transmission member 14112 are both slidably engaged with the connecting member 31, so that the fourth transmission member 14122 and the third transmission member 14112 can move in the up and down directions relative to the connecting member 31.

[0084] Among them, after the annular cutter 142 cuts the separation portion 232, the first protrusion 1424A provides support for the separation portion 232, so that the third driving member 14111 can drive the annular cutter 142 to rise through the third transmission member 14112, thereby driving the separation portion 232 away from the can body 22. In order to enable the annular cutter 142 to open a new food container 2, it is necessary to separate the separation portion 232 from the annular cutter 142. Due to the existence of the first protrusion 1424A, the separation portion 232 cannot fall freely under the total force of gravity. Therefore, by providing a separation member 32, and then connecting the separation member 32 and the fixed member through the connecting member 31, The seat 40 is connected so that the movement of the third transmission member 14112 and the fourth transmission member 14122 will not drive the separation member 32 to move together, that is, the third transmission member 14112 continues to rise under the drive of the third driving member 14111, so that the separation portion 232 abuts against the separation member 32. The third transmission member 14112 continues to rise, and the fixed separation member 32 moves downward relative to the third transmission member 14112, thereby generating a downward force on the separation portion 232, so that the separation portion 232 can smoothly separate from the first supporting portion 1424, so that the annular knife 142 can cut the sealing film of the new food container 2.

[0085] Furthermore, in one embodiment, the connecting member 31 includes a third limiting portion 311, a connecting portion 312 and a fourth limiting portion 313 connected in sequence, the third limiting portion 311 is connected to the fixed seat 40, the fourth transmission member 14122 slides with the third limiting portion 311, the sizes of the third limiting portion 311 and the fourth limiting portion 313 are both larger than the connecting portion 312, the connecting portion 312 slides with the third transmission member 14112, the third limiting portion 311 and the fourth limiting portion 313 are used to limit the sliding stroke of the third transmission member 14112, and the fourth limiting portion 313 is connected to the separating member 32. The size of the third limiting portion 311 and the size of the fourth limiting portion 313 are both larger than the size of the connecting portion 312, so that when the third transmission member 14112 slides relative to the connecting portion 312, the stroke of the third transmission member 14112 will be limited by the third limiting portion 311 and the fourth limiting portion 313, thereby preventing the third transmission member 14112 from exceeding the original stroke and causing collision with other components.

[0086] As shown in Figure 8, the outer wall of the third transmission member 14112 is provided with a plurality of first transmission teeth 14115, and the plurality of first transmission teeth 14115 are arranged in a vertical direction. The output shaft of the third driving member 14111 is provided with a first transmission wheel 14116 for engaging with the first transmission teeth 14115. The outer wall of the fourth transmission member 14122 is provided with a plurality of second transmission teeth 14126, and the plurality of second transmission teeth 14126 are arranged in a vertical direction. The output shaft of the fourth driving member 14121 is provided with a second transmission wheel 14125. The side wall 223 of the fourth transmission member 14122 is provided with a second through hole 14114, so that the second transmission wheel 14125 can pass through the second through hole 14114 and engage with the second transmission teeth 14126. This embodiment has higher precision through the meshing transmission of the first transmission wheel 14116 and the first transmission tooth 14115, which is more conducive to controlling the lifting stroke of the third transmission member 14112; the meshing transmission of the second transmission wheel 14125 and the second transmission tooth 14126 can also enable the lifting stroke of the fourth transmission member 14122 to be controlled more accurately.

[0087] As shown in FIG8 , the annular cutter 142 is disposed around the side of the third transmission member 14112. The side of the third transmission member 14112 protrudes outward to form an annular stopper protrusion 14117. The bottom of the annular stopper protrusion 14117 is configured to abut against the top of the annular cutter 142. The provision of the annular stopper protrusion 14117 in this embodiment prevents the annular cutter 142 from moving upward relative to the third transmission member 14112 during the cutting of the sealing film, which could result in the annular cutter 142 not cutting properly, and thus prevent the separation portion 232 from being completely separated from the residual portion 231, thus affecting the smooth removal of the separation portion 232.

[0088] In one embodiment, the annular cutter 142 further includes a second support portion 1425 for supporting the residual portion 231. The third transmission member 14112 drives the annular cutter to move so that the annular cutter has a fourth position. In the fourth position, the second support portion 1425 is configured to abut against the residual portion 231, thereby limiting the free fall of the residual portion 231. The provision of the second support portion 1425 allows the annular cutter 142 to abut against the residual portion 231, thereby limiting the free fall of the residual portion 231, and then, driven by the third driving member 14111, lift the can 22 after the pet has finished eating.

[0089] As shown in Figures 13 and 14, in one embodiment, the outer wall of the annular cutter 142 is provided with a plurality of second protrusions 1425A, which serve as the second support portion 1425. The plurality of second protrusions 1425A are arranged along the extension direction of the annular cutter 142, and the second protrusions 1425A are used to abut against the residual portion 231. By providing the plurality of second protrusions 1425A, this embodiment can provide reliable support for the residual portion 231. It should be noted that the second protrusions 1425A can be arc-shaped protrusions or hook-shaped protrusions. It should be noted that the second protrusions 1425A can be provided on the outer wall of the cutter body 1421 or on the outer wall of the cutting teeth 1422.

[0090] According to one embodiment of the present application, the multiple second protrusions 1425A can also be divided into a third protrusion group and a fourth protrusion group. The third protrusion group and the fourth protrusion group both include multiple second protrusions 1425A arranged in sequence along the circumference of the annular cutter 142. The third protrusion group and the fourth protrusion group are arranged at intervals along the axial direction of the annular cutter 142. The third protrusion group is located above the fourth protrusion group. The residual portion 231 generally abuts against the second support portion 1425 in the third protrusion group. Even if the tank body 22 falls relative to the annular cutter 142, the fallen residual portion 231 can still abut against the second support portion 1425 in the fourth protrusion group, thereby effectively preventing the tank body 22 from falling from the annular cutter 142.

[0091] In one embodiment, the material tray 112 is further provided with a communicating through-hole 1127. The material tray driving assembly 111 drives the material tray 112 to rotate so that the communicating through-hole 1127 has a waste station 1123. The pet feeder 1 further includes a garbage bin 15. The garbage bin 15 is provided below the material transport mechanism 11. The garbage bin 15 defines a receiving cavity with a top opening 224. The communicating through-hole 1127 is connected to the receiving cavity through the top opening 224. The claw assembly 13 is also used to clamp or release waste. The pet feeder 1 further includes a food storage mechanism 16 for storing food containers 2. The first drive assembly 1211 drives the material tray 112 to rotate, causing the receiving slot 1125 to have a discharge position 1124 corresponding to the food storage mechanism 16. When the receiving area is at the discharge position 1124, the communication hole 1127 is located at the waste position 1123. In this embodiment, when the receiving slot 1125 is at the discharge position 1124, the communication hole 1127 is located at the waste position 1123. This allows the used food container 2 to be simultaneously discharged from the communication hole 1127 into the trash bin 15 and the food storage machine to place a new food container 2 into the receiving slot 1125, effectively improving the operating efficiency of the pet feeder 1.

[0092] As shown in FIG16 , in one embodiment, the pet feeder 1 further includes a sorting device 50 disposed within the receiving chamber and used to push waste material within the receiving chamber to move. Current pet feeding devices generally manually clean food containers after pets have eaten. However, if a robot were to uniformly discard the used food containers into a trash can through a garbage port, the stacking of the food containers would result in the space within the trash can being underutilized. This would cause the stacked food containers to exceed the garbage port before filling up the trash can, preventing the robot from discarding them again. Manual cleaning of the food containers would still be necessary. Therefore, when the waste material is food container 2, this solution adds a sorting device 50 to push the food container 2 within the receiving chamber to move, preventing the stacking of food containers 2 and allowing the receiving chamber to accommodate more food containers 2.

[0093] In one embodiment, the sorting device 50 is installed on the side of the material tray 112 facing the garbage bin 15, and the material tray driving assembly 111 drives the sorting device 50 to move through the material tray 112; the sorting device 50 is installed on the material tray 112, and in the process of the first driving assembly 1211 driving the material tray 112 to rotate, the sorting device 50 will also move with the rotation of the material tray 112, thereby pushing the food container 2 in the receiving bin to move, so that the receiving bin can accommodate more food containers 2, that is, the sorting device 50 and the material tray 112 share a first driving assembly 1211, which is lower in cost than using one driving member to drive both the sorting device 50 and the material tray 112.

[0094] Furthermore, in one embodiment, the organizing device 50 includes a brush assembly 51, which includes a mounting member 511 and a plurality of bristle members 512. The plurality of bristle members 512 are mounted on the mounting member 511, which is connected to the material tray 112. The plurality of bristle members 512 are sequentially arranged along the radial direction of the material tray 112. By providing the plurality of bristle members 512 and sequentially arranging the plurality of bristle members 512 along the radial direction of the material tray 112, the brush assembly 51 can move more food containers 22 as the material tray 112 rotates.

[0095] Moreover, in one embodiment, a mounting groove 1128 is provided on the side of the material tray 112 facing the garbage bin 15 , and the mounting member 511 is connected to the groove wall of the mounting groove 1128 ; the mounting member 511 is provided in the mounting groove 1128 , which facilitates the installation and positioning of the mounting member 511 .

[0096] It should be noted that the arranging device 50 is made of a flexible material. The flexible material is used to prevent the brush member 512 from affecting the normal rotation of the material tray when it is unable to continue to push the food container 2 to move.

[0097] It should also be noted that the arranging device 50 is an integrally formed part, which makes the arranging device 50 easier to process and assemble.

[0098] As shown in Figure 17, each brush member 512 extends in the vertical direction, and the bottom of the brush member 512 is spaced apart from the bottom wall 222 of the garbage bin; the brush member 512 extends in the vertical direction, which can push more food containers 2 to move, and the bottom of the brush member 512 is spaced apart from the bottom wall 222 of the garbage bin 15, which helps the brush member 512 to push the food container 2 in a higher position to a lower position, that is, it is more conducive to the stacking of the food containers 2, so that more food containers 2 can be accommodated in the accommodating cavity.

[0099] The tray drive assembly 111 is arranged on a side of the material tray 112 away from the garbage bin 15. This arrangement ensures that the tray drive assembly 111 does not occupy space in the accommodating cavity, thereby enabling the accommodating cavity to accommodate more food containers 2.

[0100] Figures 18 to 22 show a specific embodiment of the food container 2 provided in this application.

[0101] As shown in Figures 18 to 22, the food container 2 includes a tank body 22 and a lid body 21. The tank body 22 includes a substantially disc-shaped tank body 220. The tank body 220 includes a bottom wall 222, a side wall 223, and a top opening 224. The side wall 223 includes an upper section 223a and a lower section 223b. The lower section 223b extends from the edge of the bottom wall 222 in a direction away from the bottom wall 222, and the upper section 223a extends from the edge of the lower section 223b to the top opening. The top edge of the top opening 224, on the axial section passing through the central axis of the tank body 220, the inner surface of the bottom wall 222 includes an arc segment 222a protruding toward the top opening 224, the inner surface of the lower segment 223b is sloped, and the inner diameter of the lower segment 223b gradually increases in the upward direction; the cover body 21 closes the top opening 224 to define an enclosed accommodating space between the tank body 220 and the cover body 21, and the cover body 21 is rotatably matched with the tank body 22.

[0102] In this embodiment, the design of the bottom wall 222 and the side wall 223 of the tank body 220 of the food container 2 allows the pet to easily lick the food with its tongue, making it easier for the pet to ingest food. The food container 2 not only serves as a food packaging container, but also has the function of tableware, allowing pet owners to provide wet food to their pets more conveniently.

[0103] As shown in FIG. 22 , in this embodiment, the cover 21 and the tank body 22 are threadedly engaged; in other embodiments, the cover 21 and the tank body 22 are rotationally snap-fitted.

[0104] As shown in Figure 22, the tank body 22 also includes a support boss 225, one end of the support boss 225 is connected to the outer surface of the upper part 223a, and the other end of the support boss 225 extends in a direction away from the upper part 223a. The inner surface of the support boss 225 and the outer surface of the lower part 223b form an annular groove 226.

[0105] As shown in Figure 19, the tank body 22 further includes a connecting plate 227, which is disposed in the annular groove 226 and connected to the groove wall of the annular groove 226. The solution of this embodiment can increase the structural strength of the food container 2.

[0106] As shown in Figure 21, the bottom of the support boss 225 is provided with a plurality of third latching teeth 2251, which are sequentially distributed along the bottom of the support boss 225. This embodiment can increase the structural strength of the food container 2.

[0107] As shown in Figure 21, a recessed space 212 is provided on the upper portion of the cover 21, and a third latching groove 2121 is provided on the side of the recessed space 212. The solution of this embodiment can increase the structural strength of the food container 2.

[0108] As shown in Figure 21, there are multiple third slots 2121, and the multiple third slots 2121 are sequentially distributed along the side wall 223 of the recessed space 212. The solution of this embodiment can increase the structural strength and aesthetics of the food container 2.
