Therefore, they cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0069] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0070] Please also refer to Figure 1 and Figure 2 The feeder provided in the embodiment of the present application includes a frame 100 and a feeding box 200, a feed tray assembly 300, a feeding pipeline 400, a waste box 500 and a driving mechanism 600 arranged on the frame 100; the feed tray assembly 300 is arranged below the feeding box 200; the feeding pipeline 400 is arranged between the feeding box 200 and the feed tray assembly 300, and a valve 410 is provided on the feeding pipeline 400; the waste box 500 is arranged below the feed tray assembly 300; the driving mechanism 600 has a first output part and a second output part, the first output part is connected to the valve 410, and the second output part is connected to the feed tray assembly 300.

[0071] The feeding box 200 stores pet food, such as water, nutrient solution, and liquid food. The feed tray assembly 300 serves as the primary feeding area for the pet. The feed pipe 400, a key component connecting the feeding box 200 and the feed tray assembly 300, ensures smooth food delivery from the feeding box 200 to the feed tray assembly 300. The valve 410 allows the user to control the amount of food delivered, achieving precise feeding control. The waste bin 500, located below the feed tray assembly 300, collects waste generated during the pet's feeding process, maintaining a clean and hygienic feeder. The drive mechanism 600 is the power source for the entire feeder. Its first output is connected to the valve 410, controlling its opening and closing. Its second output is connected to the feed tray assembly 300, driving the feed tray assembly 300 to either tilt or position it horizontally. When the feed tray assembly 300 is horizontal, the pet can eat. When the feed tray assembly 300 is tilted, waste from the feed tray assembly 300 can be dumped into the waste bin 500.

[0072] Compared to the prior art, the feeder provided in this embodiment of the present application features a drive mechanism 600 with a first output unit and a second output unit, enabling simultaneous control of the opening and closing of the valve 410 and the horizontal or tilting of the feed tray assembly 300, thereby improving the feeder's automation and feeding efficiency. Furthermore, the provision of a feeding box 200 and a waste bin 500, among other structures, enables automatic delivery of pet food and collection of waste, enhancing the feeder's practicality and convenience.

[0073] In one embodiment, see Figure 3 The tray assembly 300 includes a tray body 310 and a tray cover 320 . The tray cover 320 is sleeved on the tray body 310 . The shape of the tray cover 320 matches the shape of the tray body 310 .

[0074] In this embodiment, by providing a tray cover 320, food is placed directly onto the tray cover 320. The tray cover 320 is easily removable, allowing for replacement, cleaning, and disinfection, thereby improving the hygiene and usability of the feeder. Specifically, the tray cover 320 can be a disposable film cover. After each feeding, the user can simply replace the tray cover 320 with a new one, preventing food residue and bacterial growth. Furthermore, the shape of the tray cover 320 matches the shape of the tray body 310, ensuring that the tray cover 320 fits tightly against the tray body 310 during installation, preventing food from spilling through gaps and improving the cleanliness and hygiene of the feeder.

[0075] In one embodiment, see Figure 3 A raised positioning structure 311 is provided on the edge of the surface of the tray body 310 .

[0076] The positioning structure 311 mates with the inner wall of the feed tray sleeve 320. When the feed tray sleeve 320 is mounted on the feed tray body 310, the positioning structure 311 ensures that the feed tray sleeve 320 is stably fixed to the feed tray body 310, preventing it from slipping or shifting. This design not only enhances the stability of the connection between the feed tray sleeve 320 and the feed tray body 310, but also makes installation and removal of the feed tray sleeve 320 more convenient and quicker for the user. Furthermore, the provision of the positioning structure 311 enhances the overall structural stability and safety of the feeder.

[0077] In one embodiment, see Figure 3 A sensing element 322 is installed in the positioning structure 311, and the sensing element 322 is used to detect whether the material tray sleeve 320 is installed in place.

[0078] When the tray cover 320 is properly installed on the tray body 310, the sensor element 322 accurately detects it and sends a signal, ensuring the feeder can start and operate normally. If the tray cover 320 is not installed properly or is installed incorrectly, the sensor element 322 will sound an alarm, reminding the user to check and adjust it. This design not only improves the intelligence of the feeder, but also effectively avoids problems such as feeder malfunction and food spillage caused by improper installation of the tray cover 320, thereby improving the user experience and the practicality of the feeder.

[0079] In one embodiment, please refer to Figure 4 and Figure 5 The driving mechanism 600 includes a cam 610, a driving member 620 and a sliding frame 630; the cam 610 is rotatably connected to the frame 100; the driving member 620 is transmission-connected to the cam 610, and the driving member 620 is used to drive the cam 610 to rotate reciprocally; the sliding frame 630 is slidably connected to the frame 100, one end of the sliding frame 630 abuts against the cam 610, and the other end of the sliding frame 630 is fixedly connected to the valve core 411 of the valve 410, and the sliding frame 630 forms a first output part.

[0080] As the cam 610 reciprocates under the drive of the driver 620, its contour pushes the carriage 630 to slide on the frame 100. This sliding motion of the carriage 630 is converted into linear motion of the valve core 411, thereby controlling the opening and closing of the valve 410. This design enables the drive mechanism 600 to efficiently and accurately control the opening and closing of the valve 410, ensuring that the feeder can quickly and stably supply food when needed. Furthermore, the direct contact between the cam 610 and the carriage 630 reduces intermediate transmission links, improves transmission efficiency, and reduces energy consumption.

[0081] In one embodiment, please refer to Figure 7 and Figure 8The cam 610 includes a base circular portion 6110, and the edge of the side of the base circular portion 6110 has an opening groove 6102. The depth of the opening groove 6102 gradually increases or decreases along the circumferential direction of the base circular portion 6110. Figure 9 As shown; the sliding frame 630 abuts against the opening groove 6102.

[0082] When the cam 610 rotates, the depth change of the opening groove 6102 guides the sliding frame 630 to slide along the frame 100. This design not only increases the stability of the movement of the sliding frame 630, but also makes the movement trajectory of the sliding frame 630 more precise, thereby improving the accuracy of the control of the valve 410.

[0083] In one embodiment, see Figure 11 The sliding frame 630 has a recessed groove 631 , and the cam 610 is partially located in the recessed groove 631 ; the inner side wall of the recessed groove 631 has a raised abutting portion 632 , and the abutting portion 632 abuts against the opening groove 6102 .

[0084] In this embodiment, by providing a recessed groove 631, when the cam 610 rotates, the sliding frame 630 can be prevented from interfering with the cam 610. At the same time, the abutment portion 632 abuts against the opening groove 6102, and can stably transmit the rotational power of the cam 610. When the cam 610 rotates, the depth change of the opening groove 6102 can be utilized to enable the sliding frame 630 to generate linear motion in the depth direction of the opening groove 6102. The cam 610 can be rotated forward and reversed to realize the linear reciprocating motion of the sliding frame 630.

[0085] In one embodiment, see Figure 10 A sliding groove 110 is provided on the frame 100, and the sliding frame 630 is slidably connected to the sliding groove 110; a blind hole 111 is provided at the end of the sliding groove 110, and a first elastic member 112 is provided in the blind hole 111; a guide portion 633 is provided on the outer wall of the sliding frame 630, and the guide portion 633 is arranged to face away from the abutting portion 632, and the guide portion 633 is slidably connected to the blind hole 111 and abuts against the first elastic member 112.

[0086] In this embodiment, by providing the blind hole 111 and the first elastic member 112, the first elastic member 112 can provide a certain restoring force, allowing the sliding frame 630 to return to its initial position more smoothly, thereby ensuring the continuity and stability of the movement of the sliding frame 630. For example, when the cam 610 rotates forward, the depth of the open groove 6102 gradually decreases at the contact position between the open groove 6102 and the abutment 632. At this time, the open groove 6102 pushes the sliding frame 630 toward the first elastic member 112, causing the first elastic member 112 to compress. When the cam 610 rotates backward, the depth of the open groove 6102 gradually increases at the contact position between the open groove 6102 and the abutment 632, and the open groove 6102 gradually tends to separate from the abutment 632. Under the action of the restoring force of the first elastic member 112, the sliding frame 630 is pushed away from the first elastic member 112, so that the abutment 632 and the open groove 6102 always maintain contact, thereby achieving reciprocating linear motion of the sliding frame 630. This structural design not only improves the smoothness of movement, but also enhances the reliability of the system.

[0087] Specifically, the first elastic member 112 can be a spring, with one end of the spring abutting the bottom of the blind hole 111 and the other end abutting the guide portion 633, or being sleeved on the guide portion 633. The elastic force of the spring can compress the sliding frame 630 when pushed by the open slot 6102, and provide a restoring force when the open slot 6102 separates from the abutting portion 632, thereby ensuring continuous and stable movement of the sliding frame 630. In addition, the sliding connection between the guide portion 633 and the blind hole 111 can also guide the movement of the sliding frame 630, improving the accuracy of the movement.

[0088] In one embodiment, please refer to Figure 4 and Figure 12 The valve 410 also includes a valve body 412; the valve body 412 has a transition chamber 413, a liquid inlet 414 and a liquid outlet 415; the liquid outlet 415 is connected to the transition chamber 413; the valve core 411 is slidingly connected to the valve body 412, and the valve core 411 has a first position and a second position. In the first position, the valve core 411 blocks the liquid inlet 414, and in the second position, the liquid inlet 414 is connected to the transition chamber 413.

[0089] In this embodiment, the movement state of the valve core 411 can be controlled by the sliding frame 630. Specifically, when the sliding frame 630 performs reciprocating linear motion under the action of the cam 610, it can drive the valve core 411 to slide within the valve body 412. When the sliding frame 630 moves to a specific position, it pushes the valve core 411 to move to the first position. At this time, the valve core 411 is tightly fitted at the liquid inlet 414, effectively preventing liquid from flowing from the liquid inlet 414 into the transition chamber 413. When the sliding frame 630 moves in the opposite direction, it drives the valve core 411 to move to the second position. At this time, the channel between the liquid inlet 414 and the transition chamber 413 is opened, allowing liquid to smoothly flow from the liquid inlet 414 into the transition chamber 413 and then out through the liquid outlet 415. This design not only realizes the automated control of the valve 410, but also improves the efficiency and accuracy of liquid flow.

[0090] In one embodiment, see Figure 5 The material delivery pipeline 400 includes a feed pipe 420 and a discharge pipe 430. One end of the feed pipe 420 is connected to the feeding box 200, and the other end of the feed pipe 420 is connected to the liquid inlet 414; one end of the discharge pipe 430 is connected to the liquid outlet 415, and the other end of the discharge pipe 430 faces the material tray assembly 300.

[0091] In this embodiment, the provision of a feed pipe 420 and a discharge pipe 430 enables efficient and smooth delivery of pet food and fluids from the feeding box 200 to the feeding tray assembly 300. The feed pipe 420 is connected to the feeding box 200, ensuring stable food delivery to the feeding line 400. The discharge pipe 430 delivers the food directly to the top of the feeding tray assembly 300, making it easier for the pet to eat. This design not only simplifies the feeding process but also improves feeding efficiency and accuracy.

[0092] In one embodiment, see Figure 6 The driving mechanism 600 also includes a connecting rod 640, and a sliding member 641 is connected to the first end near the connecting rod 640, and the sliding member 641 is slidably connected to the cam 610; a rotating shaft 642 is provided near the second end of the connecting rod 640, and the rotating shaft 642 is rotatably connected to the frame 100; the material tray assembly 300 is connected to the rotating shaft 642, and the rotating shaft 642 forms a second output part.

[0093] As cam 610 rotates, the changes in its profile drive slider 641 to slide back and forth along connecting rod 640. This sliding motion is transmitted to shaft 642 via connecting rod 640, which in turn drives shaft 642 to rotate on frame 100. Because tray assembly 300 is connected to shaft 642, the rotational motion of shaft 642 is directly converted into rotation or oscillation of tray assembly 300, thereby enabling tray assembly 300 to be placed horizontally or tilted.

[0094] In one embodiment, see Figure 7 The cam 610 also includes a lift portion 6120. A slide groove 6103 is provided on the side of the cam 610 facing away from the exit groove 6102. The slide groove 6103 extends from the lift portion 6120 to the base circle portion 6110. The trajectory of the slide groove 6103 is a curve, and the sliding member 641 is slidably connected to the slide groove 6103.

[0095] In this embodiment, the provision of a chute 6103 allows the slider 641 to move along the trajectory of the chute 6103. When the cam 610 rotates to the lift portion 6120, the slider 641 gradually rises under the guidance of the chute 6103. This upward movement is transmitted to the rotating shaft 642 via the connecting rod 640, causing the rotating shaft 642 to gradually tilt the feed tray assembly 300. When the cam 610 rotates to the base circle portion 6110, the slider 641 gradually descends under the guidance of the chute 6103. Similarly, this downward movement is transmitted to the rotating shaft 642 via the connecting rod 640, causing the rotating shaft 642 to gradually level the feed tray assembly 300. This design not only ensures smooth tilting and leveling of the feed tray assembly 300, but also improves the continuity and stability of the movement, ensuring smooth and efficient operation of the feeder.

[0096] In one embodiment, please refer to Figure 7 and Figure 9 The cam 610 has a toothed structure 6101 on the side of the slide groove 6103 . The toothed structure 6101 is located at the edge of the base circular portion 6110 . The toothed structure 6101 is in transmission connection with the driving member 620 .

[0097] The toothed structure 6101 cleverly coordinates with the driver 620 to achieve rotational drive of the cam 610. When the driver 620 is activated, its power is transmitted to the cam 610 through the toothed structure 6101, driving the cam 610 to rotate. Because the toothed structure 6101 is located at the edge of the base circle 6110, when the cam 610 rotates, the toothed structure 6101 can smoothly engage with the driver 620, ensuring the accuracy and reliability of the rotational motion. This design not only simplifies the overall structure of the feeder, but also improves its operating efficiency and stability, allowing the feeder to more accurately complete feeding tasks.

[0098] In one embodiment, see Figure 13 A fixed shaft 643 is provided near the first end of the connecting rod 640, and the sliding member 641 is rotatably connected to the fixed shaft 643.

[0099] In this embodiment, the provision of a fixed shaft 643 allows the slider 641 to rotate relative to the fixed shaft 643, thereby increasing the flexibility of the sliding connection between the slider 641 and the chute 6103. Specifically, when the cam 610 rotates, the curved trajectory of the chute 6103 guides the slider 641 in a complex, compound motion. The rotational connection between the slider 641 and the fixed shaft 643 allows for the smooth transmission of this complex motion, ensuring that the tray assembly 300 moves along a predetermined trajectory. This design not only improves the motion accuracy and flexibility of the entire drive mechanism 600 but also enhances its ability to adapt to complex working environments.

[0100] In one embodiment, see Figure 10 The frame 100 is provided with a receiving groove 120 and a limiting portion 130, and a second elastic member 140 is provided in the receiving groove 120; please refer to Figure 14 The driving mechanism 600 also includes a tensioning member 700, the bottom of the tensioning member 700 has a blocking portion 710, and the middle part of the tensioning member 700 is rotatably connected to the frame 100; one end of the tensioning member 700 abuts against the lifting portion 6120, and the other end of the tensioning member 700 can abut against the limiting portion 130; the blocking portion 710 is located in the accommodating groove 120 and abuts against the second elastic member 140.

[0101] As the cam 610 rotates, the lift portion 6120 gradually pushes one end of the tensioning member 700, causing it to rotate about its center of rotation. As the tensioning member 700 rotates, its other end gradually approaches the stop portion 130 until it ultimately abuts against the stop portion 130. During this process, because the blocking portion 710 remains within the receiving groove 120 and abuts against the second elastic member 140, the second elastic member 140 exerts a reverse elastic force on the tensioning member 700. This elastic force helps maintain stable contact between the tensioning member 700, the lift portion 6120, and the stop portion 130, thereby enhancing the stability and reliability of the entire drive mechanism 600.

[0102] Furthermore, the provision of the tensioning member 700 and the second elastic member 140 can, to a certain extent, compensate for the increased gap between components due to prolonged use or wear. When the gap between components increases, the elastic force of the second elastic member 140 pushes the tensioning member 700 into closer contact with adjacent components, thereby reducing or eliminating the gap and ensuring the continued stable operation of the drive mechanism 600. This design not only improves the durability of the drive mechanism 600 but also reduces maintenance costs.

[0103] In one embodiment, see Figure 8 A matching groove 6104 is provided on the edge of the second surface of the lift portion 6120 , and the tensioning member 700 abuts against the lift portion 6120 at the matching groove 6104 . The matching groove 6104 has a protruding and smoothly transitioned blocking structure 6105 .

[0104] This design makes the contact between the tensioning member 700 and the lift portion 6120 more stable, making relative sliding or separation less likely to occur. The raised and smoothly transitioned blocking structure 6105 can provide additional resistance when the tensioning member 700 abuts the lift portion 6120, effectively preventing the tensioning member 700 from accidentally moving during the force application process. At the same time, this smooth transition design also reduces friction and wear between components, extending the service life of the drive mechanism 600. The provision of the matching groove 6104 also facilitates the installation and removal of the tensioning member 700, improving the maintainability of the entire drive mechanism 600.

[0105] In one embodiment, see Figure 6 The driving mechanism 600 further includes a driving gear 650 and a transmission gear 660 that mesh with each other. The driving gear 650 is connected to the driving member 620 , and the transmission gear 660 meshes with the tooth structure 6101 .

[0106] In this embodiment, the drive gear 650 is fixedly connected to the drive member 620. When the drive member 620 rotates, the drive gear 650 rotates accordingly. The transmission gear 660 is tightly engaged with the tooth structure 6101 of the cam 610, transmitting the rotational power of the drive gear 650 to the cam 610, driving it to perform reciprocating rotational motion. This gear transmission method is not only compact in structure and high in transmission efficiency, but also can achieve smooth power transmission and reduce the generation of vibration and noise. In addition, by adjusting the gear ratio of the drive gear 650 and the transmission gear 660, the rotation speed of the cam 610 can be flexibly controlled to meet the needs of different application scenarios.

[0107] Specifically, drive element 620 can utilize a servo motor, which offers high precision, high stability, and ease of control, enabling precise control of the rotational speed and position of cam 610. Driven by the servo motor, cam 610 rotates smoothly and continuously along a predetermined trajectory. This design not only improves the motion accuracy and controllability of drive mechanism 600 but also enhances its adaptability to complex operating environments, providing a more stable and efficient driving force for various automated equipment and production lines.

[0108] In one embodiment, the transmission gear 660 includes a duplex gear, an input end of the duplex gear is engaged with the driving gear 650 , and an output end of the duplex gear is engaged with the tooth structure 6101 .

[0109] In this embodiment, by providing a double gear, the structure of the drive mechanism 600 is made more compact, while achieving smooth power transmission and effective speed control. The design of the double gear enables the drive mechanism 600 to carry greater torque while maintaining a small size, thereby improving transmission efficiency and stability. In addition, the input end of the double gear is tightly meshed with the drive gear 650, ensuring lossless power transmission; its output end matches the tooth structure 6101 of the cam 610, achieving precise power transmission and stable rotation of the cam 610. This design not only optimizes the structure of the drive mechanism 600, but also improves the performance and reliability of the entire drive mechanism 600.

[0110] It is understandable that the double gear includes a first gear and a second gear arranged coaxially, wherein the first gear is engaged with the drive gear 650 as the input end, and is responsible for receiving and transmitting the rotational power from the drive gear 650; the second gear is tightly engaged with the tooth structure 6101 of the cam 610 as the output end, and converts the received power into the reciprocating rotation required by the cam 610. The coaxial arrangement of the first gear and the second gear not only simplifies the structure of the drive mechanism 600, but also makes the power transmission more direct and efficient. In addition, the number of teeth of the first gear and the second gear can be flexibly designed according to actual needs to achieve smooth power transmission and effective speed regulation. This double gear design not only improves the transmission efficiency and stability of the drive mechanism 600, but also provides a more reliable and efficient driving force for the entire drive mechanism 600.

[0111] In one embodiment, see Figure 6 The driving mechanism 600 further includes a first position sensing element 810 , which is mounted on the frame 100 and close to the cam 610 . The first position sensing element 810 is used to monitor the position of the cam 610 .

[0112] In this embodiment, by providing a first position sensing element 810, the motion state of the cam 610 can be sensed in real time, ensuring the accurate rotational position of the cam 610, thereby controlling the forward or reverse rotation of the driver 620. When the rotational position of the cam 610 reaches the desired set value, the first position sensing element 810 quickly emits a signal. After receiving and processing the signal, the control system sends a command to the driver 620, which then responds by either continuing forward rotation to maintain stable rotation of the cam 610 or reversing to adjust the position of the cam 610. This real-time monitoring and instant feedback mechanism greatly improves the accuracy and response speed of the driver mechanism 600's control of the cam 610's position, ensuring the stability and reliability of the entire system.

[0113] In one embodiment, see Figure 6The driving mechanism 600 further includes a second position sensing element 820 . The second position sensing element 820 is mounted on the frame 100 and is close to the sliding frame 630 . The second position sensing element 820 is used to monitor the position of the sliding frame 630 .

[0114] In this embodiment, the second position sensing element 820 is provided to sense the movement of the carriage 630 in real time, thereby determining whether the valve 410 is open or closed. When the carriage 630 moves to a specific position, the second position sensing element 820 generates a signal. This signal is received and processed by the control system, which then sends a command to the driver 620, thereby achieving precise control over the opening or closing of the valve 410.

[0115] In one embodiment, see Figure 5 The driving mechanism 600 further includes a third position sensing element 830 , which is mounted on the frame 100 and close to the tray assembly 300 . The third position sensing element 830 is used to monitor the position of the tray assembly 300 .

[0116] In this embodiment, by providing the third position sensing element 830 , the motion state of the tray assembly 300 can be sensed in real time to obtain the posture information of the tray, thereby ensuring the material supply to the tray.

[0117] Specifically, the first position sensing element 810, the second position sensing element 820, and the third position sensing element 830 can all be photoelectric sensors. Photoelectric sensors have the characteristics of high sensitivity, fast response speed, and good stability, and can accurately monitor the positions of the cam 610, the slide 630, and the tray assembly 300. When the cam 610, the slide 630, or the tray assembly 300 moves to a specific position, the photoelectric sensor can quickly sense and send a signal. After the signal is received and processed by the control system, the instruction is sent to the drive member 620 to achieve precise control of the rotation of the cam 610, the opening or closing of the valve 410, and the posture of the tray. This design not only improves the motion accuracy and controllability of the entire drive mechanism 600, but also enhances its ability to adapt to complex working environments, providing a more stable and efficient driving force for various automated equipment and production lines.

[0118] In one embodiment, see Figure 15 A first triangular prism structure 210 is provided on the inner wall of the bottom of the feeding box 200 , and a first liquid level detection element 150 is provided on the frame 100 . The first liquid level detection element 150 is arranged close to the first triangular prism structure 210 .

[0119] In this embodiment, by providing the first triangular prism structure 210 and the first liquid level detection element 150 , accurate detection of the liquid level of liquid food such as pet milkshake, water, milk, etc. in the feeding box 200 can be achieved.

[0120] In one embodiment, see Figure 16 The first liquid level detection element 150 includes a first transmitting end 151 and a first receiving end 152 . The first transmitting end 151 is used to transmit a signal to the liquid level to be monitored, and the first receiving end 152 is used to receive a signal reflected by the first triangular prism structure 210 .

[0121] When the first triangular prism structure 210 is not covered with liquid, the signal emitted by the first transmitting end 151 will be reflected back from the inside of the first triangular prism structure 210 and received by the first receiving end 152; when the first triangular prism structure 210 is covered with liquid, due to the presence of liquid, the signal emitted by the first transmitting end 151 will pass through the first triangular prism structure 210 and be absorbed by the liquid, and the first receiving end 152 cannot receive the signal; therefore, it is possible to determine whether there is liquid at the position of the first triangular prism structure 210 by determining whether the first receiving end 152 receives the signal.

[0122] In this embodiment, the first triangular prism structure 210 is arranged at the bottom of the feeding box 200. When the first receiving end 152 of the first liquid level detection element 150 can receive the signal emitted by the first transmitting end 151, it indicates that the liquid in the feeding box 200 has reached the lowest liquid level. At this time, the liquid needs to be replenished in time to avoid the feeding box 200 being empty of liquid, which affects the normal operation of the feeder.

[0123] In one embodiment, see Figure 16 A first groove 230 is provided on the outer wall of the feeding box 200 , and the position of the first groove 230 is opposite to the position of the first triangular prism structure 210 .

[0124] In this embodiment, by providing the first groove 230 , the propagation path of the signal transmitted by the first liquid level detection element 150 on the outer wall of the feeding box 200 is shortened, the attenuation of the signal is reduced, and the efficiency of signal transmission is improved.

[0125] In one embodiment, the cross-sectional shape of the first groove 230 is rectangular or V-shaped.

[0126] In this embodiment, the rectangular or V-shaped design of the first groove 230 makes the reflection of the signal in the first groove 230 more regular, thereby enhancing the signal transmission effect and improving the accuracy of liquid monitoring.

[0127] In one embodiment, please refer to Figure 17 and Figure 18The opening end of the feeding box 200 is provided with a box cover 220, and the edge of the box cover 220 that contacts the feeding box 200 is provided with multiple raised structures 221. The raised structures 221 are used to create an air circulation gap between the feeding box 200 and the box cover 220.

[0128] In this embodiment, the provision of raised structure 221 creates a certain gap between the lid 220 and the feeding box 200, thereby ensuring air circulation between the feeding box 200 and the lid 220. This design helps maintain air circulation within the feeding box 200, ensuring that the feeding box 200 can function properly. Furthermore, the provision of raised structure 221 increases the tension in the connection between the lid 220 and the feeding box 200, thereby improving the stability of the lid 220.

[0129] In one embodiment, please refer to Figure 15 and Figure 17 A positioning hole 171 is provided on the frame 100 , and a positioning column 240 is provided on the feeding box 200 , and the positioning column 240 cooperates with the positioning hole 171 .

[0130] In this embodiment, the coordinated arrangement of positioning post 240 and positioning hole 171 allows the feeding box 200 to be stably mounted on the frame 100, avoiding monitoring errors caused by unstable installation. This also ensures the accuracy of the positional relationship between the first liquid level detection element 150 and the first triangular prism structure 210, improving the precision and reliability of liquid monitoring. Furthermore, the provision of positioning hole 171 and positioning post 240 facilitates the removal and replacement of the feeding box 200, enhancing the maintenance efficiency of the feeder.

[0131] In one embodiment, please refer to Figure 19 and Figure 20 A second triangular prism structure 510 is provided inside the side of the waste box 500, and a second liquid level detection element 160 is provided on the frame 100. The second liquid level detection element 160 is arranged close to the second triangular prism structure 510; the height direction of the second triangular prism structure 510 is consistent with the height direction of the waste box 500.

[0132] In this embodiment, by providing a second triangular prism structure 510 and a second liquid level detection element 160, precise monitoring of the liquid level within the waste bin 500 can be achieved. When the liquid within the waste bin 500 reaches or exceeds a preset height, the second liquid level detection element 160 can accurately sense and issue a signal, thereby reminding the user to promptly dispose of the liquid within the waste bin 500. This design not only improves the accuracy of liquid level monitoring but also helps maintain the cleanliness and hygiene of the feeder, avoiding contamination and inconvenience caused by overflow from the waste bin 500. Furthermore, the height direction of the second triangular prism structure 510 aligns with the height direction of the waste bin 500, ensuring the accuracy and reliability of liquid level monitoring.

[0133] In one embodiment, see Figure 20 The second liquid level detection element 160 includes a second transmitting end 161 and a second receiving end 162 . The second transmitting end 161 is used to transmit a signal to the liquid level to be monitored, and the second receiving end 162 is used to receive a signal reflected by the second triangular prism structure 510 .

[0134] In this embodiment, the working principle of the second liquid level detection element 160 is similar to the working principle of the first liquid level detection element 150. When the second receiving end 162 can receive the signal transmitted by the second transmitting end 161, it indicates that the liquid in the waste box 500 has not reached the highest water level position, and waste can continue to be dumped into the waste box 500; when the second receiving end 162 cannot receive the signal transmitted by the second transmitting end 161, it indicates that the highest water level position in the waste box 500 has been covered by liquid, and dumping waste into the waste box 500 should be stopped, and the waste box 500 should be removed to clean the waste in the waste box 500.

[0135] In one embodiment, please refer to Figure 21 and Figure 22 A second groove 520 is provided on the outer wall of the waste box 500 , and the position of the second groove 520 is opposite to the position of the second triangular prism structure 510 .

[0136] In this embodiment, by providing the second groove 520, the propagation path of the signal emitted by the second liquid level detection element 160 on the outer wall of the waste box 500 is shortened, the attenuation of the signal is reduced, and the efficiency of signal transmission is improved.

[0137] In one embodiment, the cross-sectional shape of the second groove 520 is rectangular or V-shaped.

[0138] In this embodiment, the rectangular or V-shaped design of the second groove 520 makes the reflection of the signal in the second groove 520 more regular, thereby enhancing the signal transmission effect and improving the accuracy of liquid monitoring.

[0139] In one embodiment, see Figure 24 A receiving cavity 172 is provided in the frame 100 , and the waste box 500 is placed in the receiving cavity 172 .

[0140] In this embodiment, by providing the accommodating chamber 172, the waste bin 500 can be placed more securely, thereby avoiding monitoring errors caused by the shaking of the waste bin 500. The design of the accommodating chamber 172 can also limit the waste bin 500 to prevent it from shifting during operation, thereby ensuring the accuracy of the relative positional relationship between the second liquid level detection element 160 and the second triangular prism structure 510, and improving the accuracy and reliability of liquid monitoring. At the same time, the provision of the accommodating chamber 172 also facilitates the installation and disassembly of the waste bin 500, thereby improving the maintenance efficiency of the feeder. In addition, the accommodating chamber 172 can also protect the waste bin 500, preventing it from being disturbed and damaged by the external environment, thereby extending the service life of the waste bin 500.

[0141] In one embodiment, see Figure 24 A positioning protrusion 173 is provided in the accommodating cavity 172 , and a first positioning groove 530 is provided on the waste box 500 , and the first positioning groove 530 cooperates with the positioning protrusion 173 .

[0142] In this embodiment, the positioning protrusion 173 cooperates with the first positioning groove 530 to fix the position of the waste bin 500 in the accommodating chamber 172, preventing it from shaking or shifting during operation. This design not only improves the stability and accuracy of the feeder, but also makes the installation of the waste bin 500 easier and faster. At the same time, the cooperation between the positioning protrusion 173 and the first positioning groove 530 also has a certain guiding effect, which helps to quickly find the correct disassembly position when disassembling the waste bin 500, thereby improving the maintenance efficiency of the feeder. In addition, the design of the positioning protrusion 173 and the first positioning groove 530 can also be adjusted according to actual needs to accommodate waste bins 500 of different specifications and sizes, thereby improving the versatility and flexibility of the feeder.

[0143] In one embodiment, see Figure 23 An elastic snap buckle 174 is provided in the accommodating cavity 172 , and a second positioning groove 540 is provided on the waste box 500 , and the elastic snap buckle 174 is snapped into the second positioning groove 540 .

[0144] In this embodiment, by providing a flexible snap 174 that cooperates with the second positioning slot 540, the waste bin 500 can be quickly installed and removed. The operator simply aligns the second positioning slot 540 on the waste bin 500 with the flexible snap 174 within the accommodating cavity 172 and gently presses to complete installation. To remove the waste bin 500, simply press the flexible snap 174 to easily remove it. This design not only simplifies the installation and removal process, improving work efficiency, but also helps ensure the stability and reliability of the waste bin 500 after installation. Furthermore, the cooperation between the flexible snap 174 and the second positioning slot 540 provides a certain buffering effect, which can, to a certain extent, reduce vibration and impact of the waste bin 500 during operation, thereby extending the service life of the waste bin 500 and the feeder.

[0145] In one embodiment, see Figure 25 The elastic clip 174 includes a clip body 1741, a rebound member 1742 and a fixing member 1743. The rebound member 1742 is arranged between the clip body 1741 and the fixing member 1743. The bottom of the accommodating cavity 172 is provided with an avoidance hole 1721. The clip body 1741 is located in the avoidance hole 1721, and the fixing member 1743 is connected to the frame 100; when the rebound member 1742 is compressed, the clip body 1741 is flush with the bottom surface of the accommodating cavity 172; when the rebound member 1742 is extended, the clip body 1741 protrudes from the bottom surface of the accommodating cavity 172 and is clamped in the second positioning groove 540.

[0146] This design makes the elastic buckle 174 more flexible and reliable when fixing and releasing the waste bin 500. When the rebound member 1742 is in a compressed state, the buckle body 1741 is flush with the bottom surface of the accommodating chamber 172 and will not cause any obstruction, which facilitates the smooth insertion of the waste bin 500. When the rebound member 1742 is extended, the buckle body 1741 will protrude from the bottom surface of the accommodating chamber 172 and tightly snap into the second positioning groove 540 on the waste bin 500, thereby achieving a stable fixing effect. In addition, the setting of the avoidance hole 1721 also cleverly solves the problem of the position of the buckle body 1741 in the accommodating chamber 172, which not only ensures the normal operation of the buckle, but also avoids interference with other parts of the accommodating chamber 172. This structural design not only improves the overall performance of the feeder, but also brings a more convenient and efficient user experience to the user.

[0147] In one embodiment, please refer to Figure 21 and Figure 22 A handle 550 is provided on the outer side of the waste box 500.

[0148] In this embodiment, the provision of a handle 550 allows the operator to more conveniently move and carry the waste bin 500, thereby improving operational convenience. The handle 550 is typically designed using durable materials to ensure it is not damaged during handling while also being able to withstand a certain weight. The shape and size of the handle 550 are also appropriately designed based on the size of the waste bin 500 and the intended use scenario, ensuring that the operator can comfortably grip and easily move the waste bin 500. This design makes the feeder more user-friendly during daily use and maintenance, improving work efficiency and the operator experience.

[0149] In another embodiment of the present application, see Figure 26 The bottom surface of the feeding box 200 is provided with a capacitance sensor 250, and the bottom surface of the outside of the feeding box 200 is provided with a signal control board 260, which is electrically connected to the capacitance sensor 250; the capacitance sensor 250 is used to detect the height change of the liquid level inside the feeding box 200. When the surface of the capacitance sensor 250 is not covered with liquid, its capacitance value will change, and the signal control board 260 detects the height of the liquid level based on the change in the capacitance value of the capacitance sensor 250. This design provides another means of monitoring the liquid level in the feeding box 200, increasing the diversity and flexibility of liquid level monitoring. The capacitance sensor 250 has the characteristics of high precision and high sensitivity, and can reflect the changes in the liquid level in real time and accurately, ensuring the accuracy of the monitoring results. At the same time, the electrical connection design between the capacitance sensor 250 and the signal control board 260 makes the transmission and processing of signals more efficient and reliable, thereby improving the overall performance of the feeder.

[0150] In one embodiment, see Figure 2 The feeder also includes a control circuit board 910, which is arranged on the frame 100 and is used to receive signals from various sensors and control the operation of each drive component 620. As the "brain" of the entire feeder, the control circuit board 910 is responsible for processing and analyzing signals from various position sensing elements, liquid level detection elements, etc., and issuing instructions to the drive mechanism 600 according to preset programs and logic to achieve precise control of functions such as the rotation of the cam 610, the opening and closing of the valve 410, the posture of the tray assembly 300, and liquid monitoring. This design enables the feeder to achieve automated and intelligent operation, greatly improving work efficiency and accuracy. At the same time, the control circuit board 910 also has fault self-detection and alarm functions. When the system fails or an abnormal situation occurs, it can quickly issue an alarm signal to remind the user to deal with it in time, ensuring the stable operation and safety of the feeder.

[0151] In one embodiment, see Figure 2The feeder also includes a battery 920, which is arranged on the frame 100 and is used to provide power support for the entire feeder. This design allows the feeder to continue to operate normally in the event of a power outage or no power supply outdoors, ensuring the continuous operation and reliability of the feeder. The battery 920 usually uses a high-performance, long-life battery to ensure that it can provide stable power output during long-term use. At the same time, the battery 920 is also equipped with an intelligent power management system that can monitor the battery power in real time and issue a reminder when the power is low so that the user can charge or replace the battery in time. This design not only improves the convenience of use of the feeder, but also ensures its stable operation in various environments.

[0152] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
