Description

[Technical Field]

[0001] This invention relates to the field of pet supplies technology, and in particular to a feeder. [Background Technology]

[0002] With the increasing number of pet owners and the faster pace of life, there is a need for more convenient feeding methods, and pet feeders have emerged to meet this need.

[0003] There are various types of pet feeders on the market now, with functions covering timed feeding, intelligent monitoring, and health management, meeting the needs of different pet owners. Especially popular are pet feeders that combine feeding with interaction, allowing pets to not only be fed but also interact with their pets by launching food. However, the delivery systems and processes of these feeders are complex. When delivering cat or dog food, it often requires passing through multiple devices to get the food out of the device, which can easily lead to problems during delivery and reduce the efficiency of interactive feeding. [Summary of the Invention]

[0004] To address the problem that existing pet feeders have complex delivery systems and processes, which can easily lead to problems with food delivery and reduce the efficiency of interactive feeding, this invention provides a feeder.

The launching device includes a first housing, a launching structure, and a driving module and a control module disposed inside the first housing. The driving module is connected to the launching structure.

[0006] The first housing has a discharge port and an opening communicating with the grain storage bin. The launching structure includes a projectile channel that enters the grain storage bin through the opening and a projectile device disposed in the projectile channel.

[0007] The control module controls the drive module to rotate, thereby driving the launching structure to rotate so that the projectile inlet of the projectile channel enters the grain storage bin. After further rotating until the projectile inlet aligns with the discharge outlet, the control module starts the ejection device.

[0009] The first driving unit is connected to the second housing of the launching structure and is used to drive the launching device to rotate;

[0010] The second drive unit is connected to the ejector device that partially extends out of the material channel, and is used to drive the ejector device to slide in the material channel in the direction close to the material inlet or to drive it in the opposite direction to make the ejector device slide and reset in the direction away from the material inlet.

[0011] Preferably, the first drive unit includes a first motor connected to the control module, and a positioning component is also provided inside the first housing. The positioning component is disposed opposite to the first motor. A first positioning structure and a second positioning structure are respectively provided at both ends of the second housing.

[0012] Preferably, the launching structure includes a feeding assembly located inside the second housing, the feeding assembly forming the projectile channel, the feeding assembly having a groove, and a portion of the ejection device extending out of the groove and connecting to the second drive unit.

[0015] Preferably, a slide bar is provided on the feed cylinder along the spring material channel, and a slider is provided on the gear part, the slider being slidably connected to the slide bar.

[0016] Preferably, a stop member is provided at one end of the feeding cylinder near the feeding port of the feeding channel, and the stop member corresponds to the gear part; when the first motor drives the ejector device to eject the grain in the feeding channel out of the discharge port, the end of the gear part of the ejector device near the feeding port abuts against the stop member.

[0017] Preferably, a support is provided at the end of the upper feeding cylinder away from the lower feeding cylinder, and a pressure plate is provided on the support, with the second motor disposed between the support and the pressure plate.

[0018] Preferably, a triggering part is provided on the first housing, and a power supply is provided inside the first housing. The power supply is connected to the control module. The triggering part is provided with multiple buttons, which are respectively connected to the control module and used to generate different triggering commands in response to triggering operations. The control module controls the drive module to drive the launching structure to rotate and the ejection device to slide according to the triggering commands.

[0019] Compared with the prior art, the feeder provided by the present invention has the following advantages:

[0020] 1. This invention provides a feeder, comprising a launching device and a grain storage bin arranged sequentially along the direction of gravity. The launching device includes a first housing, a launching structure, and a driving module and a control module disposed inside the first housing. The driving module is connected to the launching structure. The first housing has a discharge port and an opening communicating with the grain storage bin. The launching structure includes a feed channel that enters the grain storage bin through the opening and a catapult device disposed within the feed channel. The control module controls the driving module to rotate, thereby driving the launching structure to rotate so that the feed port of the feed channel enters the grain storage bin. After further rotation until the feed port aligns with the discharge port, the control module activates the catapult device. By connecting the drive module to the launching structure, the drive module can drive the launching structure to rotate. The launching structure then uses this rotation to scoop up food from the storage bin located below the launching device. When it rotates to align with the discharge port, the food is launched via a catapult located in the feed channel. Thus, during the entire food launching process, after the food is scooped from the storage bin and placed in the feed channel, it is transported solely by the automatic rotation of the launching structure, eliminating the need for other transport devices. This simplifies the food transport system and process, making the food delivery and launching process simpler and faster, thereby improving the efficiency of interactive feeding. Furthermore, even if food falls into the feed channel during rotation, it will fall into the storage bin and will not affect the launching device. Therefore, the need for a separate sealed transport pipe avoids the situation in existing pet feeders where the storage bin is located above the launching structure, where food falls into the feeder during transport and cannot be cleaned up.

[0021] 2. The driving module in this embodiment of the invention includes a first driving unit and a second driving unit. The launching structure includes a second housing, and a projectile channel passes through the second housing. The control module is signal-connected to the first driving unit and the second driving unit respectively. The first driving unit is connected to the second housing of the launching structure and is used to drive the launching device to rotate. The second driving unit is connected to the ejection device that partially extends out of the projectile channel and is used to drive the ejection device to slide in the projectile channel along the direction close to the projectile opening or drive it in the opposite direction to make the ejection device slide and reset in the direction away from the projectile opening. By setting up the first driving unit and the second driving unit, the rotation of the launching structure as a whole and the sliding of the ejection device on the projectile channel can be driven by different driving modules, thereby improving the flexibility and accuracy of the driving.

[0022] 3. In this embodiment of the invention, the first driving unit includes a first motor connected to the control module. A positioning component is also provided inside the first housing, positioned opposite to the first motor. A first positioning structure and a second positioning structure are respectively provided at both ends of the second housing. The first positioning structure is connected to the first motor, and the second positioning structure is rotatably connected to the positioning component. By positioning the component opposite to the first motor, the overall structure after the positioning component and the first positioning structure are connected will also be in a relative state with the overall structure after the second positioning structure and the first motor are connected. This limits the current position of the launching device and allows them to be arranged sequentially in a straight line. Therefore, when the first motor drives the launching device to rotate, it can rotate around this straight line as an axis, thus limiting the rotation direction of the launching device and preventing overall movement or deviation in the rotation direction, thereby making the overall rotation of the launching device more stable.

[0023] 4. The launching structure in this embodiment of the invention includes a feeding assembly, within which a projectile channel is formed. A groove is provided on the feeding assembly, and a portion of the launching device extends out of the groove to connect with the second driving unit. The groove simplifies the sliding of the launching device within the projectile channel and also makes it easier for a portion of the launching device to extend and connect with the driving unit, thus simplifying the driving and sliding of the launching device.

[0024] 5. In this embodiment of the invention, the second drive unit includes a second motor and a power gear connected to the second motor. The second motor is connected to a control module. The ejection device includes a projectile cylinder and a gear section. The projectile cylinder is located within the projectile channel, and the gear section extends out of the projectile channel and meshes with the power gear. This enables the second motor to drive the ejection device to slide within the projectile channel to complete the digging and ejection of grain, thereby achieving high-precision control of the grain ejection and ensuring consistency in each ejection.

[0025] 6. In this embodiment of the invention, a sliding rod is provided on the upper edge of the feed cylinder along the spring material channel, and a slider is provided on the gear part. The slider and the sliding rod are slidably connected. Thus, when the spring cylinder slides in the spring material channel, the slider will also slide on the sliding rod. This further limits the gear part extending out of the spring material channel by the sliding rod, preventing the gear part extending out of the spring material channel from shaking during the sliding process and affecting the connection with the power gear.

[0026] 7. In this embodiment of the invention, a stop member is provided at one end of the feed cylinder near the feed outlet of the feed channel, and the stop member corresponds to the gear part; when the first motor drives the ejector device to eject the grain in the feed channel out of the discharge port, the end of the gear part of the ejector device near the feed outlet abuts against the stop member. This achieves the limitation of the movement distance of the ejector device in the ejection channel along the direction near the feed outlet by the abutment of the stop member, and avoids excessive sliding of the ejector device.

[0027] 8. In this embodiment of the invention, a support is provided at the end of the upper feeding cylinder away from the lower feeding cylinder, and a pressure plate is provided on the support. The second motor is positioned between the support and the pressure plate, thereby firmly fixing the second motor to the upper feeding cylinder by the clamping of the support and the pressure plate, improving the stability of the connection between the second motor and the ejection device through the power gear. In addition, the pressure plate can protect the second motor and prevent the second motor from directly contacting the second housing.

[0028] 9. In this embodiment of the invention, a trigger unit is provided on the first housing, and a power supply is provided inside the first housing. The power supply is connected to the control module. Multiple buttons are provided on the trigger unit, and each button is connected to the control module to generate different trigger commands in response to trigger operations. The control module controls the drive module to drive the launching structure to rotate and the ejection device to slide according to the trigger commands. The button-triggered design makes the grain launching control more intuitive, easier for users to understand and operate, and allows users to quickly get started. Furthermore, it makes the user's operating intentions clearer, effectively reducing erroneous operations caused by accidental touches. [Attached Image Description]

Detailed Implementation Methods

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0042] Please see Figure 1 and Figure 2 The first embodiment of the present invention provides a feeder 1, including a launching device 10 and a grain storage bin 20 arranged sequentially along the direction of gravity. The launching device 10 includes a first housing 11, a launching structure 12, and a driving module 13 and a control module 15 disposed inside the first housing 11. The driving module 13 is connected to the launching structure 12.

[0043] The first housing 11 has a discharge port 111 and an opening 112 that communicates with the grain storage bin 20. The launching structure 12 includes a projectile channel 1223 that enters the grain storage bin 20 through the opening 112 and a projectile device 123 disposed in the projectile channel 1223.

[0044] The control module 15 controls the drive module 13 to rotate, thereby driving the launching structure 12 to rotate so that the projectile port 1229 of the projectile channel 1223 enters the grain storage bin 20. After further rotation until the projectile port 1229 corresponds to the discharge port 111, the control module 15 controls the launching device 123 to start.

[0045] Specifically, a launching device 10 and a grain storage bin 20 are arranged sequentially along the direction of gravity, with the grain storage bin 20 located below the launching device 10. An opening 112 is formed on the first housing 11 of the launching device 10 corresponding to the position of the grain storage bin 20. This opening 112 communicates with the grain storage bin 20, and the launching structure 12 is positioned corresponding to this opening 112. Part of the launching structure 12 is located inside the first housing 11, while another part is located inside the grain storage bin 20. This creates a rotational space for the entire launching structure 12 to rotate, allowing it to rotate directly above the grain storage bin 20, as the first housing 11 of the launching device 10 communicates with the grain storage bin 20 through the opening 112. The control module 15 can be a main control PCB board. Using a main control PCB board as the control module 15 provides reliable electrical connections, enables compact component layout, reduces production costs, improves production efficiency, and facilitates maintenance and upgrades.

[0046] Understandably, the connection between the drive module 13 and the launching structure 12 allows the drive module 13 to drive the launching structure 12 to rotate on the grain storage bin 20. When the launching structure 12 rotates, it drives the feed channel 1223 to rotate as well, causing the feed inlet 1229 of the feed channel 1223 to rotate into the grain stored in the grain storage bin 20 below the launching device 10. This allows the grain to enter the feed channel 1223 from the feed inlet 1229 and abut against the ejection device 123, thus realizing the retrieval of grain from the storage bin using the rotation of the launching structure 12 itself. When the feed inlet 1229 of the feed channel 1223 rotates to correspond with the discharge port 111, the retrieval of grain is launched by the ejection device 123 located within the feed channel 1223, allowing the grain to enter the outside through the discharge port 111. Therefore, in the overall process of digging, conveying, and launching food, after the food is dug out from the food storage bin 20 and is located only in the feed channel 1223, it is conveyed only by the automatic rotation of the launching structure 12, without the need for other conveying devices. This simplifies the food conveying system and process, making the food conveying and launching process simpler and faster, thereby improving the efficiency of interactive feeding. In addition, even if the food in the feed channel 1223 of the feeder 1 in this embodiment of the invention falls during rotation, it will fall into the food storage bin 20 due to gravity and will not fall into the launching device 10, thus not affecting the launching device 10. Therefore, it is not necessary to set up a separate sealed conveying pipe to avoid the situation in existing pet feeders 1 where the food storage bin 20 is set above the launching structure 12 and the food falls into the feeder 1 during the conveying process and cannot be cleaned up.

[0047] It should be noted that the launching device 10 and the grain storage silo 20 are detachably connected to facilitate the filling of grain into the grain storage silo 20, as well as the disassembly, maintenance, and cleaning of both the launching device 10 and the grain storage silo 20. In this embodiment, the method of detachable connection between the launching device 10 and the grain storage silo 20 is not limited, as long as it allows for disassembly without causing damage to either device.

[0048] Please see Figure 2 and Figure 3 Furthermore, the drive module 13 includes a first drive unit 131 and a second drive unit 132, the launching structure 12 includes a second housing 121, the ammunition channel 1223 passes through the second housing 121, and the control module 15 is signal connected to the first drive unit 131 and the second drive unit 132 respectively.

[0049] The first drive unit 131 is connected to the second housing 121 of the launch structure 12 and is used to drive the launch device 10 to rotate.

[0050] The second drive unit 132 is connected to the ejector 123 that extends out of the material channel 1223, and is used to drive the ejector 123 to slide in the material channel 1223 in the direction close to the material port 1229 or drive it in the opposite direction to make the ejector 123 slide and reset in the direction away from the material port 1229.

[0051] Specifically, the first drive unit 131 is connected to the second housing 121 of the launching structure 12, which enables the first drive module 13 to drive the launching structure 12 to rotate on the grain storage bin 20, so that the material channel 1223 of the launching structure 12 can complete the digging and transportation of grain through rotation.

[0052] More specifically, the second drive unit 132 is connected to the ejector device 123 that partially extends out of the material channel 1223, enabling the ejector device 123 to slide within the material channel 1223. Specifically, when the first drive unit 131 drives the launching structure 12 to rotate as a whole, so that the material outlet 1229 of the material channel 1223 corresponds to the discharge outlet 111 of the first housing 11, the second drive unit 132 can drive the ejector device 123 to slide within the material channel 1223 in a direction close to the material outlet 1229 to eject the grain in the material channel 1223 out of the discharge outlet 111. After ejecting the grain and before retrieving it, the ejector device 123 can be driven to slide away from the material inlet 1229 and stop after sliding to a preset distance from the material inlet 1229, i.e., sliding reset. This creates a receiving space between the side of the ejector device 123 near the material inlet 1229 and the material channel 1223, used to receive the retrieving grain and limit the sliding space and distance for ejection by the ejector device 123. By setting the preset distance value, the sliding distance of the ejector device 123 during ejection within the material channel 1223 can be controlled, as can the amount of grain retrieving each time. The longer the preset distance value, the more grain can be retrieving in a single operation.

[0053] Therefore, by setting the first drive unit 131 and the second drive unit 132 to be connected to the control module 15 respectively, it is possible to drive the rotation of the launching structure 12 as a whole and the bidirectional sliding of the ejector device 123 on the projectile channel 1223 with different drive units. That is, the rotation of the launching structure 12 as a whole is controlled and driven separately and the bidirectional sliding of the ejector device 123 on the projectile channel 1223 is controlled and driven separately, which is more conducive to improving the flexibility and accuracy of the drive.

[0054] Optionally, as another embodiment of driving the ejector device 123 to slide within the material channel 1223, the ejector device 123 may be connected to an elastic element. After the ejector device 123 is driven to slide away from the material outlet 1229 in the material channel 1223, the elastic element deforms. During ejection, the elastic element returns to its original shape and generates an elastic force on the ejector device 123, causing the ejector device 123 to slide away from the material outlet 1229 under the action of the elastic force, thereby realizing ejection.

[0055] Please see Figures 2-4 Furthermore, the first drive unit 131 includes a first motor 1311 connected to the control module 15, and a positioning component 14 is also provided inside the first housing 11. The positioning component 14 is disposed opposite to the first motor 1311. The second housing 121 has a first positioning structure 1211 and a second positioning structure 1212 respectively at both ends. The first positioning structure 1211 is connected to the first motor 1311, and the second positioning structure 1212 is rotatably connected to the positioning component 14.

[0056] Understandably, in this embodiment, the overall rotation of the launching structure 12 can be driven by a motor, which can improve the controllability and accuracy of the overall rotation of the launching structure 12. The positioning component 14 can further limit the position of the launching structure 12, preventing the launching structure 12 from shaking or shifting during rotation, thereby avoiding misalignment between the projectile port 1229 and the discharge port 111 during final ejection.

[0057] Specifically, the positioning component 14 can be arranged opposite to the first motor 1311. The first positioning structure 1211 and the second positioning structure 1212 respectively provided at both ends of the second housing 121 will be arranged corresponding to the positioning component 14 and the first motor 1311, that is, the first positioning structure 1211 and the second positioning structure 1212 are located at opposite ends of the second housing 121 and are arranged opposite to each other. Thus, the overall structure after the positioning component 14 and the first positioning structure 1211 are connected will also be in a relative state with the overall structure after the second positioning structure 1212 and the first motor 1311 are connected, limiting the launching device 10 to its current position and arranging them sequentially in a straight line. This allows the first motor 1311 to drive the launching device 10 to rotate around this straight line as an axis, thereby limiting the rotation direction of the launching device 10 and preventing overall movement or deviation in the rotation direction, thus making the overall rotation of the launching device 10 more stable.

[0058] Please combine Figure 2 and Figure 4Furthermore, the launching structure 12 includes a feeding assembly 122 located inside the second housing 121. A projectile channel 1223 is formed inside the feeding assembly 122. A groove 1224 is provided on the feeding assembly 122. Part of the ejection device 123 extends out of the groove 1224 and connects to the second drive unit 132.

[0059] Understandably, the feeding assembly 122 is located inside the second housing 121, and the second housing 121 can protect the feeding assembly 122. Furthermore, the groove 1224 simplifies the sliding of the ejector device 123 within the material channel 1223, and also makes it easier for parts of the ejector device 123 to extend and connect with the drive unit, thus simplifying the driving and sliding of the ejector device 123.

[0060] Please combine Figure 2 and Figure 4 Furthermore, the feeding assembly 122 includes an upper feeding cylinder 1221 and a lower feeding cylinder 1222, which are engaged to form a spring material channel 1223 and a chute 1224.

[0061] Understandably, the engagement of the upper feed cylinder 1221 and the lower feed cylinder 1222 to form the material channel 1223 and the chute 1224 makes the installation of the ejection device 123 easier and more flexible. At the same time, the separate upper feed cylinder 1221 and lower feed cylinder 1222 also make it easier to control the size of the chute 1224.

[0062] Please see Figures 3-5 Furthermore, the second drive unit 132 includes a second motor 1321 and a power gear 1322 connected to the second motor 1321. The second motor 1321 is connected to the control module 15. The ejection device 123 includes a projectile section 1231 and a gear section 1232. The projectile section 1231 is located in the projectile channel 1223, and the gear section 1232 extends out of the projectile channel 1223 and meshes with the power gear 1322.

[0063] Understandably, in this embodiment, the ejection device 123 can also be driven by a motor. The second motor 1321 in the second drive unit 132 is connected to the power gear 1322, which is connected to the gear portion 1232 extending from the material channel 1223. Through the power gear 1322, the power generated by the second motor 1321 can be accurately and efficiently transmitted to the ejection device 123, enabling the second motor 1321 to drive the ejection device 123 to slide within the material channel 1223 to complete the digging and ejection of the grain. This achieves high-precision control of the grain ejection, ensuring consistency in each ejection. Furthermore, the power gear 1322 allows for a more compact structure in the second drive unit 132, saving space.

[0064] Specifically, the entire projectile section 1231 of the ejection device 123 is located within the projectile channel 1223. The shape of the projectile section 1231 is consistent with that of the projectile channel 1223, both being cylindrical structures. The outer diameter of the projectile section 1231 is smaller than the inner diameter of the projectile channel 1223. This diameter relationship must ensure that the excavated grain will not enter or be trapped between the inner wall of the projectile channel 1223 and the outer wall of the projectile section 1231. The bottom wall of the projectile section 1231 that abuts against the excavated grain and the gear section 1232 are arranged sequentially along the direction close to the projectile opening 1229. That is, the bottom wall of the projectile section 1231 that abuts against the excavated grain is closer to the projectile opening 1229 than the gear section 1232, thereby preventing the excavated grain from slipping out of the chute 1224.

[0065] Please see Figure 4 and Figure 5 Furthermore, a slide bar 1227 is provided on the feed cylinder 1222 along the spring material channel 1223, and a slider 1233 is provided on the gear part 1232, with the slider 1233 slidably connected to the slide bar 1227.

[0066] Understandably, the slider 1233 is sleeved on the slide rod 1227 and slidably connected to the slide rod 1227. Thus, when the cartridge part 1231 slides in the material channel 1223, the slider 1233 will also slide on the slide rod 1227. This further limits the gear part 1232 extending out of the material channel 1223 through the slide rod 1227, preventing the gear part 1232 extending out of the material channel 1223 from shaking during the sliding process, which would affect the connection with the power gear 1322 and affect the stability of the ejector device 123 ejecting the grain.

[0067] It should be noted that by using a motor-driven catapult 123 to slide within the projectile channel 1223, high-precision control of the catapult launch angle, launch speed, and launch distance can be achieved. Furthermore, the motor-driven catapult can be quickly started and stopped, improving launch efficiency and making it suitable for frequent launch requirements.

[0068] Optionally, as an embodiment where the ejector device 123 slides within the feed channel 1223, an elastic element can be provided on the slide rod 1227. When the slider 1233 of the ejector device 123 is sleeved on the slide rod 1227, the elastic element can also be connected. When the ejector device 123 slides away from the feed inlet 1229, the elastic element deforms. During ejection, the elastic element returns to its original shape, generating a spring force on the slider 1233 of the ejector device 123. This spring force causes the entire ejector device 123 to slide away from the feed inlet 1229, thus ejecting the grain. Using an elastic element as the power source for ejecting grain results in a simple structure, lower manufacturing cost, and no need for an additional power source, enabling ejection to be completed without power.

[0069] Please see Figure 5 Furthermore, a stop member 1228 is provided at one end of the feed cylinder 1222 near the feed port 1229 of the feed channel 1223, and the stop member 1228 corresponds to the gear part 1232; when the first motor 1311 drives the ejector device 123 to eject the grain in the feed channel 1223 out of the discharge port 111, the end of the gear part 1232 of the ejector device 123 near the feed port 1229 abuts against the stop member 1228.

[0070] Understandably, the stop member 1228 is provided corresponding to the gear part 1232. The stop member 1228 restricts the movement distance of the ejector device 123 in the ejection channel along the direction close to the projectile inlet 1229, thus preventing excessive sliding of the ejector device 123. In addition, the stop member 1228 can also buffer the sliding of the ejector device 123, preventing excessive sliding of the ejector device 123 from causing impact damage to the lower housing.

[0071] Optionally, the stop member 1228 can be a flexible member. The flexible member can limit the movement distance of the ejection device 123 in the ejection channel along the direction close to the feed port 1229, while also improving the buffering effect on the ejection device 123 and further protecting the ejection device 123.

[0072] Please see Figure 3 and Figure 4 Furthermore, a support 1225 is provided at the end of the feed cylinder 1221 away from the feed cylinder 1222, and a pressure plate 1226 is provided on the support 1225. The second motor 1321 is located between the support 1225 and the pressure plate 1226.

[0073] Understandably, since the second motor 1321 needs to be connected to the control module 15, the configuration of the second motor 1321 also needs to consider the circuit connection with the control module 15. Therefore, in order to facilitate the circuit connection between the second motor 1321 and the control module 15, the second motor 1321 is preferably located outside the material channel 1223. A bracket 1225 is set at the end of the upper cylinder 1221 away from the lower cylinder 1222 to fix the second motor 1321 on the upper cylinder 1221. A wire passage 1213 can be set in the second positioning structure 1212, and a pin PCB board 141 can be set on the positioning component 14. The pin PCB board 141 is connected to the control module 15 through the pin. The wires of the second motor 1321 can enter the wire passage cavity and connect with the pin on the positioning component 14, thereby realizing the circuit connection between the second motor 1321 and the control module 15.

[0074] It should be noted that, in order to facilitate the circuit connection between the second motor 1321 and the control module 15, the second motor 1321 is located outside the material channel 1223. Therefore, the second motor 1321 and the ejection device 123 cannot be directly driven. Therefore, a power gear 1322 is required and part of the ejection device 123 is exposed. That is, the gear part 1232 is exposed outside the material channel 1223 so that the power of the second motor 1321 is transmitted to the gear part 1232 through the power gear 1322 to complete the overall movement of the ejection device 123.

[0075] Specifically, a pressure plate 1226 is provided on the bracket 1225, thereby forming a clamping space between the bracket 1225 and the pressure plate 1226. This clamping space secures the second motor 1321 firmly to the feed cylinder 1221, improving the stability of the connection between the second motor 1321 and the ejector device 123 via the power gear 1322. Furthermore, the pressure plate 1226 protects the second motor 1321, preventing it from directly contacting the second housing 121.

[0076] Please see Figure 2 Furthermore, a trigger part 113 is provided on the first housing 11, and a power supply 16 is provided inside the first housing 11. The power supply 16 is connected to the control module 15. Multiple buttons 1131 are provided on the trigger part 113. The multiple buttons 1131 are respectively connected to the control module 15 and are used to generate different trigger commands in response to trigger operations. The control module 15 controls the drive module 13 to drive the launching structure 12 to rotate and the ejection device 123 to slide according to the trigger commands.

[0077] Understandably, as one implementation method for powering the feeder 1, a power supply can be installed inside the feeder 1, and power can be supplied to the feeder 1 via power supply 16. Power supply 16 can be a rechargeable power supply for repeated charging and use. Alternatively, it can be a disposable power supply, extending the service life of the feeder 1 by replacing power supply 16. This implementation comparison is not limited, as long as it can supply power to the control module 15 and the drive module 13. Furthermore, the setting of triggering the drive with button 1131 makes the feed dispensing control more intuitive, easier for users to understand and operate, and allows users to quickly get started. In addition, it makes the user's operating intentions clearer, effectively reducing erroneous operations caused by accidental touches.

[0078] As another embodiment of powering the feeder 1, a data interface 114 can be provided on the launching device 10. This data interface 114 can be connected to the control module 15 to power the feeder 1 and transmit data via an external power supply.

[0079] Optionally, a power supply 16 and a data interface 114 can be set simultaneously to supply power to the feeder 1 through multiple power supply modes, making it easier to select different power supply methods according to different situations and making it more convenient for users to use.

[0080] Optionally, a wireless module can be installed inside the transmitter 10 to connect with the control module 15, so that the rotation of the launching structure 12 and the sliding of the ejection device 123 in the transmitter 10 can be controlled by mobile devices such as mobile phones. The wireless module allows users to customize the ejection distance and the amount of ejected grain, which helps to meet the needs of different users.

[0081] Optionally, a prompting device 17 connected to the control module 15 can be provided on the transmitting device 10. The prompting device 17 can be an audio prompting device, such as a horn or a buzzer; it can also be a display device, such as a lamp or a display screen; or it can be both an audio prompting device 17 and a display device, to provide prompts when the feeder 1 is working.

[0082] Compared with the prior art, the feeder provided by the present invention has the following advantages:

[0083] 1. This invention provides a feeder, comprising a launching device and a grain storage bin arranged sequentially along the direction of gravity. The launching device includes a first housing, a launching structure, and a driving module and a control module disposed inside the first housing. The driving module is connected to the launching structure. The first housing has a discharge port and an opening communicating with the grain storage bin. The launching structure includes a feed channel that enters the grain storage bin through the opening and a catapult device disposed within the feed channel. The control module controls the driving module to rotate, thereby driving the launching structure to rotate so that the feed port of the feed channel enters the grain storage bin. After further rotation until the feed port aligns with the discharge port, the control module activates the catapult device. By connecting the drive module to the launching structure, the drive module can drive the launching structure to rotate. The launching structure then uses this rotation to scoop up food from the storage bin located below the launching device. When it rotates to align with the discharge port, the food is launched via a catapult located in the feed channel. Thus, during the entire food launching process, after the food is scooped from the storage bin and placed in the feed channel, it is transported solely by the automatic rotation of the launching structure, eliminating the need for other transport devices. This simplifies the food transport system and process, making the food delivery and launching process simpler and faster, thereby improving the efficiency of interactive feeding. Furthermore, even if food falls into the feed channel during rotation, it will fall into the storage bin and will not affect the launching device. Therefore, the need for a separate sealed transport pipe avoids the situation in existing pet feeders where the storage bin is located above the launching structure, where food falls into the feeder during transport and cannot be cleaned up.

[0084] 2. The driving module in this embodiment of the invention includes a first driving unit and a second driving unit. The launching structure includes a second housing, and a projectile channel passes through the second housing. The control module is signal-connected to the first driving unit and the second driving unit respectively. The first driving unit is connected to the second housing of the launching structure and is used to drive the launching device to rotate. The second driving unit is connected to the ejection device that partially extends out of the projectile channel and is used to drive the ejection device to slide in the projectile channel along the direction close to the projectile opening or drive it in the opposite direction to make the ejection device slide and reset in the direction away from the projectile opening. By setting up the first driving unit and the second driving unit, the rotation of the launching structure as a whole and the sliding of the ejection device on the projectile channel can be driven by different driving modules, thereby improving the flexibility and accuracy of the driving.

[0085] 3. In this embodiment of the invention, the first driving unit includes a first motor connected to the control module. A positioning component is also provided inside the first housing, positioned opposite to the first motor. A first positioning structure and a second positioning structure are respectively provided at both ends of the second housing. The first positioning structure is connected to the first motor, and the second positioning structure is rotatably connected to the positioning component. By positioning the component opposite to the first motor, the overall structure after the positioning component and the first positioning structure are connected will also be in a relative state with the overall structure after the second positioning structure and the first motor are connected. This limits the current position of the launching device and allows them to be arranged sequentially in a straight line. Therefore, when the first motor drives the launching device to rotate, it can rotate around this straight line as an axis, thus limiting the rotation direction of the launching device and preventing overall movement or deviation in the rotation direction, thereby making the overall rotation of the launching device more stable.

[0086] 4. The launching structure in this embodiment of the invention includes a feeding assembly, within which a projectile channel is formed. A groove is provided on the feeding assembly, and a portion of the launching device extends out of the groove to connect with the second driving unit. The groove simplifies the sliding of the launching device within the projectile channel and also makes it easier for a portion of the launching device to extend and connect with the driving unit, thus simplifying the driving and sliding of the launching device.

[0087] 5. In this embodiment of the invention, the second drive unit includes a second motor and a power gear connected to the second motor. The second motor is connected to a control module. The ejection device includes a projectile cylinder and a gear section. The projectile cylinder is located within the projectile channel, and the gear section extends out of the projectile channel and meshes with the power gear. This enables the second motor to drive the ejection device to slide within the projectile channel to complete the digging and ejection of grain, thereby achieving high-precision control of the grain ejection and ensuring consistency in each ejection.

[0088] 6. In this embodiment of the invention, a sliding rod is provided on the upper edge of the feed cylinder along the spring material channel, and a slider is provided on the gear part. The slider and the sliding rod are slidably connected. Thus, when the spring cylinder slides in the spring material channel, the slider will also slide on the sliding rod. This further limits the gear part extending out of the spring material channel by the sliding rod, preventing the gear part extending out of the spring material channel from shaking during the sliding process and affecting the connection with the power gear.

[0089] 7. In this embodiment of the invention, a stop member is provided at one end of the feed cylinder near the feed outlet of the feed channel, and the stop member corresponds to the gear part; when the first motor drives the ejector device to eject the grain in the feed channel out of the discharge port, the end of the gear part of the ejector device near the feed outlet abuts against the stop member. This achieves the limitation of the movement distance of the ejector device in the ejection channel along the direction near the feed outlet by the abutment of the stop member, and avoids excessive sliding of the ejector device.

[0090] 8. In this embodiment of the invention, a support is provided at the end of the upper feeding cylinder away from the lower feeding cylinder, and a pressure plate is provided on the support. The second motor is positioned between the support and the pressure plate, thereby firmly fixing the second motor to the upper feeding cylinder by the clamping of the support and the pressure plate, improving the stability of the connection between the second motor and the ejection device through the power gear. In addition, the pressure plate can protect the second motor and prevent the second motor from directly contacting the second housing.

[0091] 9. In this embodiment of the invention, a trigger unit is provided on the first housing, and a power supply is provided inside the first housing. The power supply is connected to the control module. Multiple buttons are provided on the trigger unit, and each button is connected to the control module to generate different trigger commands in response to trigger operations. The control module controls the drive module to drive the launching structure to rotate and the ejection device to slide according to the trigger commands. The button-triggered design makes the grain launching control more intuitive, easier for users to understand and operate, and allows users to quickly get started. Furthermore, it makes the user's operating intentions clearer, effectively reducing erroneous operations caused by accidental touches.
