Description

Pet feeder Technical Field

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

[0002] There are usually only two ways to handle used pet cans in pet feeders in the related art: one is to stack the used pet cans with a robotic arm, which will cause the stacked pet cans to emit an odor, seriously affecting the user experience; the other is to set up a storage area inside the pet feeder specifically for storing used cans. However, in actual operation, this method is not only difficult to remove the cans from the storage area, but also cannot be conveniently cleaned. If the storage area is not cleaned for a long time, it is easy to produce an odor.

[0003] Application Contents

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a pet feeder that can effectively solve the technical problem that it is difficult for users to take canned waste after consumption.

[0005] In order to achieve the above-mentioned object, the present application provides a pet feeder, wherein the pet feeder includes a waste receiving mechanism, wherein the waste receiving mechanism includes:

[0006] A shell having a cavity, wherein a side wall of the shell is provided with an inlet and outlet hole communicating with the cavity;

[0007] A garbage bin defines a receiving cavity for accommodating waste, and the garbage bin can be moved between a first position and a second position through the inlet and outlet holes. In the first position, the receiving cavity is located inside the cavity, and in the second position, the receiving cavity is located outside the cavity.

[0008] In the above technical solution of the present application, waste is centrally stored through the trash bin. When it is time to discard waste, the user can move the trash bin from the first position to the second position so that the trash bin is located outside the cavity, making it convenient for the user to centrally dispose of the waste in the trash bin and operating it conveniently. At the same time, when waste needs to be stored, the trash bin is located inside the cavity, and the housing helps prevent the spread of odors generated by the waste. This technical solution effectively improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The pet feeder provided in the present application is shown in Figures 1 to 3. The pet feeder includes a garbage holding mechanism 1, which includes a shell 11 and a garbage bin 12. The shell 11 has a cavity 113, and the side wall of the shell 11 is provided with an inlet and outlet hole 114 connected to the cavity 113; the garbage bin 12 defines a receiving cavity 123 for accommodating waste. The garbage bin 12 can move between a first position 124 and a second position 125 through the inlet and outlet hole 114. In the first position 124, the receiving cavity 123 is located inside the cavity 113, and in the second position 125, the receiving cavity 123 is located outside the cavity 113.

[0028] In this embodiment, waste is collected in a centralized manner through the garbage bin 12. When waste needs to be discarded, the user can move the garbage bin 12 from the first position 124 to the second position 125 so that the garbage bin 12 is located outside the cavity 113, which is convenient for the user to centrally process the waste in the garbage bin 12 and is easy to operate. At the same time, when waste needs to be collected, the garbage bin 12 is located in the cavity 113, and the shell 11 helps prevent the spread of odor generated by the waste.

[0029] It should be noted that when the garbage bin 12 is located at the first position 124 , the side wall of the garbage bin 12 can close the inlet and outlet holes 114 , further confining the odor emitted by the waste materials within the housing 11 .

[0030] As shown in Figures 1 and 2, in this embodiment, the waste bin 12 further includes a cover 122 connected to the bin body 121. In the first position 124, the cover 122 seals the inlet and outlet openings 114. By sealing the inlet and outlet openings 114 with the cover 122, the waste bin 12 further effectively confines odors emitted by the waste within the housing 11, thereby improving the user experience.

[0031] In one embodiment, the garbage bin includes a bin body 121, which defines a receiving cavity 123 having a top opening 126. The bin body 121 slidably engages with the inner wall of the cavity 113. The bin body 121 slidably engages with the inner wall of the cavity 113 to enable the bin body 121 to reciprocate relative to the housing 11 between a first position 124 and a second position 125. This facilitates a user to easily extract the bin body 121 from the cavity 113 or insert the bin body 121 into the cavity 113.

[0032] In one embodiment, a guide rail 115 is provided on the inner wall of the cavity 113, and the bin body 121 is slidably engaged with the guide rail 115. In this embodiment, the guide rail 115 is provided to enable the bin body 121 to move relative to the housing 11 along a predetermined path.

[0033] In one embodiment, the housing 11 includes an upper housing 111 and a lower housing 112, which are fastened together to form a cavity 113. The upper housing 111 and the lower housing 112 are detachably connected and can be separated to facilitate assembly of the housing.

[0034] In one embodiment, a first through hole 1111 is provided on the top of the upper shell 111, which is connected to the top opening 126. The garbage holding mechanism 1 also includes a material tray device and a gripping device. The material tray device includes a material tray 13 and a first drive assembly. The first drive assembly is transmission-connected to the material tray 13. The material tray 13 is provided with a connecting through hole 131. The first drive assembly drives the material tray 13 to move so that the connecting through hole 131 has a waste position 1311; the garbage bin 12 is arranged below the material tray device. At the waste position 1311, the first through hole 1111 is connected to the accommodating chamber 123 through the connecting through hole 131; the gripping device includes a claw assembly and a second drive assembly. The claw assembly is used to clamp or release waste. The second drive assembly is transmission-connected to the claw assembly to drive the claw assembly to move. The connecting through hole 131 is at the waste position 1311. The claw assembly can throw the waste into the accommodating chamber 123 through the connecting through hole 131. In this embodiment, after the pet has finished eating the canned food, the eaten canned food is collectively referred to as waste. The second drive assembly drives the claw assembly to clamp the waste, and the first drive assembly drives the material tray 13 to rotate so that the connecting through hole 131 moves to the waste station 1311. When the connecting through hole 131 is located at the waste station 1311, the connecting through hole 131 is connected to the accommodating chamber 123 through the first through hole 1111, and the second drive assembly drives the claw assembly to release the waste so that the waste can pass through the connecting through hole 131 and the first through hole 1111 into the accommodating chamber 123. This reciprocating process realizes automatic cleaning and storage of waste.

[0035] In one embodiment, the material tray 13 is positioned within the cavity 113. A receiving slot 132 for accommodating canned food is provided on the side of the material tray 13 facing away from the waste bin 12. A second through-hole 1112 is provided at the top of the upper housing 111. A first drive assembly drives the material tray 13 to connect the receiving slot 132 with the second through-hole 1112. In this embodiment, if the second through-hole 1112 serves as a feeding port, then the receiving slot 132 contains uncapped pet canned food, allowing the pet to consume through the second through-hole 1112. If the second through-hole 1112 corresponds to a lid opening / closing station, the pet feeder's food container 30 opening mechanism / food container 30 closing mechanism opens or closes the canned food in the receiving slot 132 through the second through-hole 1112.

[0036] There is a pet feeder in the related art, which can also use the garbage bin 12 pull-out structure designed in this application. Specifically, this pet feeder also includes a mounting frame and a feeding device. The garbage holding mechanism 1 is arranged on the top of the mounting frame. The garbage bin 12 defines a holding cavity 123 for accommodating waste. The bottom of the garbage bin 12 is provided with a feed port that passes through the shell 11. The garbage bin 12 can move between a first position 124 and a second position 125 through an inlet and outlet hole 114. In the first position 124, the holding cavity 123 is located in the cavity 113. In the second position 125, the holding cavity 123 is located outside the cavity 113; the feeding device includes a feeding drive assembly and a feeding piece that is transmission-connected to the feeding drive assembly. The feeding piece is used to accommodate waste. The feeding drive assembly can drive the feeding piece to move to the bottom of the feed port and feed the waste into the holding cavity 123 through the feed port through the feeding piece. After the pet has finished eating the canned food, the feeding drive assembly drives the feeding piece to move so that the feeding piece containing the waste moves to the bottom of the feed inlet, and then the feeding drive assembly drives the feeding piece to feed the waste into the accommodating cavity 123.

[0037] It should be noted that the feed drive assembly includes a displacement drive component and a push component, which are transmission-connected to the feed piece. The displacement drive component is connected to the push component, and is used to drive the feed piece to move through the push component, so that the feed piece can move to the bottom of the feed port, and then the push component drives the feed piece to rise and push the waste material in the feed piece into the accommodating chamber 123. Undoubtedly, this embodiment also has the advantage of improving user experience.

[0038] As shown in Figures 1 to 4, in one embodiment, at least one of the contact surfaces between the cavity 113 and the bin body 121 is provided with a rib 127, which extends along the direction of movement of the trash bin 12. The provision of the rib 127 effectively enhances the strength of the structural member provided with the rib 127. According to one embodiment of the present application, the bottom of the bin body 121 is provided with multiple ribs 127, which extend along the sliding direction of the bin body 121 relative to the housing 11. This reduces the contact area between the bin body 121 and the inner wall of the cavity 113 during the drawing process, thereby reducing vibration and loss caused by friction and making the bin body 121 less susceptible to deformation.

[0039] In one embodiment, the housing 11 includes a stopper 116 for limiting the upward movement of the trash bin 12. One end of the stopper 116 is connected to the inner wall of the cavity 113, and the other end of the stopper 116 extends away from the housing 11. In this embodiment, the stopper 116 is provided to limit the movement of the trash bin 12, ensuring that the trash bin 12 can slide smoothly relative to the housing 11.

[0040] As shown in Figures 5 to 10, in one embodiment, the pet feeder further includes a food container opening mechanism 2 and a detection device 22. The food container opening mechanism 2 includes a lifting device 21. The lifting device 21 includes a lifting drive assembly 211 and a bracket 212 that is transmission-connected to the lifting drive assembly 211. The lifting drive assembly 211 is used to drive the bracket 212 to move in the up and down directions to multiple positions; the detection device 22 includes a signal transmitter 221 and multiple signal receivers 222. The relative positions of the multiple signal receivers 222 and the shell 11 are fixed. The signal transmitter 221 is provided on the lifting device 21. When the bracket 212 is at one of the multiple positions, at least one signal receiver 222 is provided corresponding to the signal transmitter 221.

[0041] In this embodiment, the process of opening the food container 30 and the process of handling the cover body 122 both require that the lifting drive assembly 211 drive the bracket 212 connected thereto to accurately stay at different height positions. A signal receiver 222 is provided at each position where the bracket 212 needs to stay, and the signal transmitter 221 is provided on the lifting device 21. At each position where the bracket 212 needs to stay, the signal emitted by the signal transmitter 221 can be received by at least one signal receiver 222. After the signal receiver 222 receives the signal, the lifting drive assembly 211 stops operating so that the bracket 212 can accurately stay at the position where it needs to stay, thereby ensuring the stable operation of the pet feeder.

[0042] It should be noted that the pet feeder also includes a controller, and each signal receiver 222 is connected to the controller for communication. The controller is also connected to the lifting drive assembly 211 for communication. After receiving the signal, the signal receiver 222 transmits the information to the controller, and the controller then controls the lifting drive assembly 211 to stop running.

[0043] In one embodiment, the lifting drive assembly 211 includes a lifting drive member 2111 and a transmission member 2112 in a transmission connection. The transmission member 2112 is provided with a lifting portion 21123. The bracket 212 is connected to a rolling member 2121. The lifting portion 21123 and the rolling member 2121 are in rolling engagement. The lifting drive member 2111 drives the transmission member 2112 to move left and right, so that the lifting portion 21123 can drive the bracket 212 to move up and down. The lifting drive member 2111 can drive the transmission member 2112 to move back and forth in the left and right directions. By providing the lifting portion 21123, when the lifting drive member 2111 drives the transmission member 2112 to move left, the lifting portion 21123 can guide the bracket 212 to move upward; when the lifting drive member 2111 drives the transmission member 2112 to move right, the lifting portion 21123 can guide the bracket 212 to move downward, thereby converting the left and right movement of the transmission member 2112 into up and down movement of the bracket 212 through the lifting portion 21123.

[0044] It should be noted that the rolling element 2121 may be a first rolling wheel, and the rolling cooperation between the first rolling wheel and the bottom wall of the slideway produces less friction than the sliding cooperation between the bracket 212 and the slide groove 21124 .

[0045] The transmission member 2112 further includes a pressing portion 21126 and a transition portion 21125. The transition portion 21125 is connected to the lifting portion 21123. The pressing portion 21126 is located above the transition portion 21125. When the rolling element 2121 leaves the lifting portion 21123 and rolls toward the transition portion 21125, the pressing portion 21126 cooperates with the bracket 212 to reduce the distance between the rolling element 2121 and the transition portion 21125. In the embodiment of the present application, when the bracket 212 moves on the transmission member 2112, such as when the rolling element 2121 falls from the lifting portion 21123 and is intended to fall above the transition portion 21125, the rolling element 2121 of the bracket 212 will be suspended above the transmission member 2112. At this time, the pressing portion 21126 will press the bracket 212 downward to reduce the distance between the rolling element 2121 and the transition portion 21125.

[0046] In one embodiment, multiple signal receivers 222 are arranged in sequence in the left-right direction, and the signal transmitter 221 is disposed on the transmission member 2112. The left-right movement of the transmission member 2112 drives the signal transmitter 221, so that the signal transmitter 221 sequentially corresponds to the multiple signal receivers 222. When the lifting drive member 2111 drives the transmission member 2112 in the left-right direction, the signal transmitter 221 located on the transmission member 2112 also moves therewith. Since the multiple signal transmitters 221 are also arranged in sequence in the left-right direction, the transmission member 2112 moving in the left-right direction drives the signal transmitter 221 to pass through the multiple signal transmitters 221 in sequence.

[0047] According to one embodiment of the present application, the signal transmitter 221 is set on the bracket 212, and multiple signal receivers 222 are arranged in sequence along the up and down directions. The bracket 212 moves along the up and down directions, so that at the position where the bracket 212 stops, there is at least one signal receiver 222 that can receive the signal sent by the signal transmitter 221.

[0048] In one embodiment, the plurality of signal receivers 222 include a first signal receiver 2221, and the plurality of positions include a downward position. In the downward position, the first signal receiver 2221 is positioned corresponding to the signal transmitter 221, and the rolling element 2121 is located at the end of the transition portion 21125 away from the lifting portion 21123. When the bracket 212 is in the downward position, the first signal receiver 2221 can receive a signal from the signal transmitter 221, which is then transmitted to the controller. The controller then controls the lifting drive 2111 to stop moving, thereby allowing the bracket 212 to accurately remain in the downward position.

[0049] In one embodiment, the multiple signal receivers include a second signal receiver 2222, and the multiple positions include a capping position. In the capping position, the second signal receiver 2222 is positioned corresponding to the signal transmitter 221, and the rolling element 2121 is located at one end of the transition portion 21125 near the lifting portion 21123. When the bracket 212 is in the capping position, the second signal receiver 2222 receives a signal from the signal transmitter 221, which is then transmitted to the controller. The controller then controls the lifting drive 2111 to stop moving, allowing the bracket 212 to accurately remain in the capping position.

[0050] In one embodiment, the plurality of signal receivers includes a third signal receiver 2223, and the plurality of positions includes a lid-lifting position. In the lid-lifting position, the third signal receiver 2223 is positioned corresponding to the signal transmitter 221, and the rolling element 2121 is located on the lifting portion 21123. When the bracket 212 is in the lid-lifting position, the third signal receiver 2223 receives a signal from the signal transmitter 221, which is then transmitted to the controller. The controller then controls the lifting drive 2111 to stop moving, thereby allowing the bracket 212 to accurately remain in the lid-lifting position.

[0051] In one embodiment, the multiple signal receivers include a fourth signal receiver 2224, and the multiple positions include a cap-dropping position. In the cap-dropping position, the fourth signal receiver 2224 is positioned corresponding to the signal transmitter 221, and the rolling element 2121 is located at the end of the lifting portion 21123 away from the transition portion 21125. The multiple signal receivers include a third signal receiver 2223, and the multiple positions include a cap-lifting position. In the cap-lifting position, the third signal receiver 2223 is positioned corresponding to the signal transmitter 221, and the rolling element 2121 is located at the lifting portion 21123. When the bracket 212 is in the cap-dropping position, the fourth signal receiver 2224 receives a signal from the signal transmitter 221, which is then transmitted to the controller. The controller then controls the lifting drive 2111 to stop moving, allowing the bracket 212 to accurately remain in the cap-dropping position.

[0052] In one embodiment, the first signal receiver 2221, the second signal receiver 2222, the third signal receiver 2223 and the fourth signal receiver 2224 are arranged in sequence from right to left; since the signal transmitter 221 is installed on the transmission member 2112, when the can needs to be opened, the transmission member 2112 will start to move from right to left, so that the signal reflector passes through the first signal receiver 2221, the second signal receiver 2222, the third signal receiver 2223 and the fourth signal receiver 2224 in sequence, and enables the bracket 212 to accurately stay in the pressing position, the rotating cover position, the lifting cover position and the throwing cover position respectively.

[0053] According to an embodiment of the present application, the surfaces of the pressing portion 21126 and the lifting portion 21123 facing each other are parallel to each other. This arrangement can make the appearance of the transmission member 2112 more beautiful.

[0054] In one embodiment, the detection device 22 is a photoelectric sensor, the signal transmitter 221 is a photoelectric transmitter, and the signal receiver is a photoelectric receiver; according to one embodiment of the present application, the detection device 22 is a magnetic field sensor, the signal transmitter 221 is a magnetic signal transmitter 221, and the signal receiver is a magnetic signal receiver; according to another embodiment of the present application, the detection device 22 is a mechanical switch, the signal transmitter 221 is a mechanical protrusion, and the signal receiver is a mechanical button.

[0055] In one embodiment, the first drive assembly further includes a bracket 212, a second drive member is mounted on the bracket 212, and the lifting device 21 includes a second drive member and a transmission member 2112 in a transmission connection. The transmission member 2112 is provided with a lifting portion 21123. The lifting portion 21123 is in rolling engagement with the bracket 212. The second drive member drives the transmission member 2112 to move left and right, so that the lifting portion 21123 can drive the bracket 212 to move up and down. In this embodiment, the second drive member can drive the transmission member 2112 to move back and forth in the left and right directions. By providing the lifting portion 21123, when the second drive member drives the transmission member 2112 to move left, the lifting portion 21123 can guide the bracket 212 to move upward; when the second drive member drives the transmission member 2112 to move right, the lifting portion 21123 can guide the bracket 212 to move downward, thereby converting the left and right movement of the transmission member 2112 into up and down movement of the bracket 212 through the lifting portion 21123.

[0056] In one embodiment, the transmission member 2112 includes a lifting body 21121 and a rack 21122 connected to each other. The lifting portion 21123 is provided on the lifting body 21121. The output shaft of the second driving member is provided with a gear 21111 for meshing with the rack 21122. This embodiment achieves transmission through the meshing of the gear 21111 and the rack 21122, thereby effectively improving transmission accuracy.

[0057] Those skilled in the art can easily think of realizing the reciprocating movement of the transmission member 2112 through a screw assembly, that is, the output shaft of the second driving member is connected to the screw of the screw assembly, and the lifting part 21123 is connected to the slider of the screw assembly, which can also realize the reciprocating movement of the transmission member 2112.

[0058] Moreover, in one embodiment, the height of the lifting portion 21123 is arranged to increase along the extension direction of the rack 21122, wherein the height of the lifting portion 21123 gradually increases along the extension direction of the rack 21122, so that the lifting movement of the first mounting frame can be smoother.

[0059] The lifting portion 21123 is formed with a slide groove 21124. The bracket 212 is connected to a rolling element 2121. At least a portion of the rolling element 2121 extends into the slide groove 21124 and rolls against the bottom wall of the slide groove 21124. The rolling element 2121 can be a first rolling wheel. The rolling engagement of the first rolling wheel with the bottom wall of the slideway reduces friction compared to the sliding engagement between the bracket 212 and the slide groove 21124.

[0060] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present application.
