Description

Technical Field

[0001] This invention relates to the field of pet feeding and management equipment technology, specifically to an intelligent pet butler. Background Technology

[0002] Pet waste disposal is a persistent headache for pet owners, and there are even potential safety hazards involved, especially since cat and dog feces can contaminate hands, water, and food, potentially transmitting various parasitic diseases. For example, the infection rate of Toxocara canis in puppies is around 80%, while in cats it ranges from 10% to 75%. When cats and dogs defecate or lie down indiscriminately, their fur becomes contaminated with roundworm eggs, which can contaminate water and food, leading to Toxocara migraine in humans. Mild cases may be asymptomatic or only present with unusual behaviors and an increase in eosinophils. Severe cases can cause fever, abdominal pain, vomiting, hepatomegaly, and seizures. Frequently playing with dogs can also lead to the accidental ingestion of Echinococcus granulosus eggs, resulting in echinococcosis. Currently, research on robotic methods for handling cat and dog waste in China is very limited, and most households still rely on manual cleaning. Therefore, automating the operation of machinery in this field is essential for freeing up hands and protecting health.

[0003] In existing solutions, document CN216363089U discloses a pet butler robot, including a carrier shell with a feeding compartment inside; a laying frame installed on one side of the movable compartment, with laying fans on both sides of the laying frame and a storage frame on top; two sets of movable carrier plates; a feeding plate rotatably installed inside the feeding compartment; and a closed plate on top of the carrier shell. The laying fans cooperate with the barrier frame A to blow and lay the material. After a certain period of blowing and laying, the drive motor drives the barrier plate to reset, and at the same time, the adjustment motor drives the climbing partition to rotate and adjust, so that the pet can return to the top of the feeding plate after eating. However, this solution cannot smoothly and flexibly handle pet (especially cat) excrement. Summary of the Invention

[0004] This invention provides an intelligent pet care system that has at least the advantages of automatically cleaning up feces and feeding food.

The inner bottom wall of the can compartment is located between the two belt conveyors. A servo motor six is ​​fixedly installed at the angle of the conveyor belt. A G gear is fixedly installed on the output shaft of the servo motor six. An H gear meshes above the G gear. A feeding plate is fixedly installed on the outer side of the shaft of the H gear. Two symmetrically arranged can hoppers are fixedly installed on the inner wall of the can hopper. A tray is set between the cans inside the can hopper. The can hopper is located above the transverse belt conveyor. A limit frame is fitted on the outer side of the longitudinal belt conveyor. The front end of the limit frame is open and corresponds to the feeding plate. A notch is opened on the surface of the limit frame, which corresponds to the belt ring of the transverse belt conveyor. A servo motor seven is embedded in the vertical plate of the can hopper. A short curved rod is fixedly installed at the output end of the servo motor seven. A long curved rod is hinged to the other end of the short curved rod. A push ring is hinged to the other end of the long curved rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The servo motor nine drives the J gear to rotate, which in turn drives the short rack to unfold synchronously. The pulley seat then slides along the guide rail to both sides, and the chuck unfolds. Conversely, when the chuck is controlled to close, it clamps the outer connecting rods on both sides of the litter scoop. The servo motor ten drives the K gear to roll on the long rack, and the chuck, carrying the litter scoop, scoops up the feces and litter in the litter compartment. The servo motor eleven drives the M gear to rotate, which in turn drives the L gear to rotate. The L gear drives the insertion sleeve and insertion rod to rotate, and the insertion rod drives the roller to rotate. The roller's rotation then moves the strip... The through-hole opens, allowing feces and litter to fall into a garbage bag inside the drawer. The garbage bag is then secured inside the litter box drawer, allowing the owner to change it regularly to clean up feces and maintain the litter box's hygiene. A servo motor drives a B-bevel gear via a three-way coupling, which in turn drives an A-bevel gear. The A-bevel gear then drives a threaded blade to rotate along the shaft, dispensing pre-stored dry food from the upper food storage container through the feeding port for the pet to eat. This automated feeding process ensures that the pet receives food on demand, even when the owner is not home. Attached Figure Description

[0022] Please see Figure 21-24 The cleaning component 9 includes a litter scoop 91. The litter scoop 91 is slidably mounted to the litter compartment 4 on both sides via sliders and slide bars. The sliders on both sides of the litter scoop 91 are connected to the inner side of the clamp 64 via external connecting rods 92. The front end of the litter compartment 4 is slidably connected to a drawer box 93. A roller 94 with a strip-shaped through hole is rotatably mounted on the bottom wall of the litter compartment 4 and above the drawer box 93. A plug rod 95 is fixedly mounted on the side of the roller 94. The plug rod 95 is inserted into a plug sleeve 96. An L gear 97 is fixedly mounted on the outside of the plug rod 95. An M gear 98 meshes with the side of the L gear 97. The M gear 98 is mounted at the same height as the output end of the servo motor 11 99. The servo motor 11 99 is fixedly mounted on the frame of the feed compartment 3 via a support.

[0023] When moving: Servo motor 105 drives gear A 106 to rotate, gear A 106 drives gear B 107 to rotate, gear B 107 drives gear C 108 to rotate, and gear C 108 drives drive wheel 109 to roll; servo motor 1010 drives gear D 1011 to rotate, gear D 1011 rotates in gear ring 102, and then turntable 103 also rotates in fixed ring 101. Finally, drive wheel 109 turns. Through the synchronous operation of the four drive components 10, the entire breeding house can be moved. By controlling the two drive components 10 on the left to move to the left and the two drive components 10 on the right to move to the right, the food compartment 2 and the feed compartment 3 will open in opposite directions, thus providing greater adaptability and flexibility. The pet house can also extend or retract according to actual needs to better accomplish various tasks. This telescopic mechanism also brings more possibilities to the pet house, making it more convenient and practical in daily use and providing a better experience for pet owners.

[0024] When feeding canned goods: In the canning hopper 720, each can has a tray underneath it, such as... Figure 11-12 This design aims to prevent the base of the top can from interlocking with the lid of the bottom can when cans are stacked, thus facilitating the removal of the cans. After the user selects a specific wet food brand and flavor, servo motor 721 drives the short crank rod 722 to rotate, which in turn drives the long crank rod 723 to move forward. The push ring 724 at the front end of the long crank rod 723 pushes the selected can onto a horizontally positioned belt conveyor. Figure 12 Then, the horizontally positioned belt conveyor transports the cans to the longitudinal belt conveyor below the can opener assembly 7; Next, servo motor 71 drives the lead screw shaft 72 to rotate, allowing the drive arm 73 to move up and down, thus adjusting the can opener 712 to the can's position. Servo motor 78 drives gears F and C (bevel gears) to rotate; gear F rotates around gear E, allowing the can opener 712 to perform a circular cut. Simultaneously, bevel gear C drives bevel gear D to rotate, which in turn rotates the can opener 712, causing it to cut the can lid along the can's surface. At the same time, the electromagnet 77 below activates, attracting the metal can lid and preventing it from falling off. After opening the can, the can opener assembly 7 returns to its original position, ready to open the next can. Finally, servo motor 716 drives the dispensing plate 719 to rotate and attach to the belt ring 714. The longitudinal belt conveyor transports the opened canned food to the dispensing plate 719, whereupon the can slides down to the ground, completing the feeding process. This design automates, expedits, and speeds up the wet food feeding process, allowing owners to feed their pets wet food even when they are not at home. Similar to dry food dispensers, wet food dispensers will also remind owners to replenish the food when it's low. Pet Manager will send notifications via a side display or mobile app to remind owners to check the canned food levels, ensuring that pets can continuously enjoy healthy wet food feedings. The wet food feeding device is an intelligent feeding function of Pet Butler. Its four parts, namely canned food storage, canned food transportation, can opening, and feeding, work closely together to provide pet owners with a convenient, fast, and reliable wet food feeding function to meet the dietary needs of their pets.

[0025] When feeding dry food: There are two feed dispensing components 8, which allows it to feed two different kinds of food at the same time, meeting the feeding needs of multi-pet families, and also allowing a single pet to enjoy different flavors of cat food to choose and mix freely.

[0026] The spiral blade 83 is a key component of the feed dispensing assembly 8. Its three-layer spiral design effectively ensures the airtightness of stored food such as cat food, preventing moisture and spoilage. It also precisely controls the amount of freeze-dried food or cat food delivered by adjusting the number of rotations, ensuring pets receive the appropriate amount of food. This design allows for a more scientific and healthy diet for pets, preventing health problems caused by overfeeding or underfeeding.

[0027] When the food dispenser displays a low food level, the Pet Butler will extend its reach and open the lid at the top of the food compartment 81, allowing pet owners to replenish the food. This design makes the Pet Butler very convenient to use, allowing owners to check and add food at any time, ensuring their pets don't go hungry due to insufficient food.

[0028] When feeding begins, servo motor 86 drives bevel gear 85 to rotate via a coupling. Bevel gear 85 drives bevel gear 84 to rotate, which in turn drives threaded blade 83 to rotate along the shaft. Threaded blade 83 then dispenses pre-stored dry food from the upper food storage container through the feeding port for the pet to eat. This automated feeding process ensures that the pet receives food on demand, even when the owner is not at home.

[0029] When dispensing cat litter: The cat litter is pre-stored in the cat litter bin 51. The servo motor 8 54 drives the I gear 52 to rotate, and the I gear 52 drives the adjacent I gear 52 to rotate synchronously. Then, the two bin baffles 53 open synchronously, and the cat litter will fall from the cat litter bin 51 into the cat litter compartment 4. The servo motor 10 68 drives the K gear 69 to roll on the long rack 610, and then the cat litter bin 51 will also move, which can make the cat litter dispensed evenly.

[0030] When cleaning feces: Servo motor 67 drives J gear 66 to rotate, which in turn drives short rack 65 to unfold synchronously. Then, pulley seat 63 slides to both sides along guide rail 62, and then chuck 64 unfolds. Conversely, when chuck 64 is brought closer, it clamps the outer connecting rods 92 on both sides of litter scoop 91. Servo motor 68 drives K gear 69 to roll on long rack 610, and chuck 64, along with litter scoop 91, removes feces and litter from litter compartment 4. The scooping action is achieved by servo motor 1199 driving M gear 98 to rotate, which in turn drives L gear 97 to rotate. L gear 97 then drives plug sleeve 96 and plug rod 95 to rotate, which in turn drives roller 94 to rotate. The rotation of roller 94 opens the strip-shaped through hole, allowing feces and cat litter to fall into the garbage bag in drawer box 93. The garbage bag is then fixed inside the litter box drawer, allowing the owner to change the garbage bag regularly to clean up feces and maintain the hygiene of the litter box.

[0031] The intelligent pet butler provided by this invention adopts a low-center-of-gravity steering wheel layout and a symmetrical sliding rail layout, which ensures overall balance during extension and retraction, optimizes space utilization, and occupies a small footprint. The steering motion of the chassis steering wheels drives the extension and retraction rails, achieving overall robot extension and retraction without the need for an additional motor, eliminating redundant drive components. This invention proposes a clever solution of "gripper linkage + roller-type cat litter handling," facilitating automatic cat litter replenishment and enabling fully unmanned operation from scooping and packing to refilling cat litter. This invention can adapt to cans of different heights, using a collaborative mechanism of "rotating blade + electromagnet adsorption" for precise can opening. Dual motors drive the blade to rotate and cut along the edge of the can, avoiding blade jamming or can deformation caused by traditional straight cutting, ensuring the can lid separates completely without falling into the food, and the can slides off after opening.
