Description

[Technical Field]

[0001] This utility model relates to the field of pet supplies technology, and in particular to an intelligent pet feeder with food preservation and timed and quantitative feeding functions. [Background Technology]

[0002] As people's living standards improve, pet ownership is becoming increasingly common. Pet feeders, as a convenient tool for pet owners to manage their pets' diet, are widely used. Maintaining the freshness of wet food or food that needs to be preserved for extended periods is a significant challenge.

[0003] Currently, most pet feeders on the market use built-in frozen blue ice for preservation. This method has several drawbacks: First, users need to freeze the blue ice daily before putting it into the feeder, which is cumbersome and time-consuming to maintain. Second, the blue ice refrigeration can cause localized excessively low temperatures in the food, which can easily lead to indigestion, diarrhea, or bloating in pets. Furthermore, the existing automatic feeders use a vertically stacked refrigeration module, resulting in a thicker and less compact device; moreover, the connections between the components are not tight, making it easy for cold air to leak, causing cross-contamination of hot and cold air, insufficient food refrigeration, and wasted energy.

[0004] Therefore, there is an urgent need for a new type of pet feeder that is highly efficient in refrigeration and has a compact structure. [Utility Model Content]

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. To achieve the above objective, this utility model provides a pet feeder, including a shell assembly, a food tray assembly, a temperature regulating assembly, and a controller. The shell assembly includes an upper shell and a lower shell that can be opened and closed, forming a cavity when the upper shell and the lower shell are fastened together. The food tray assembly is disposed within the cavity and is used to hold food. The temperature regulating assembly is disposed within the cavity and is used to regulate the temperature of the environment in which the food tray assembly is located. The controller is embedded in the shell assembly and is used to control the working state of the temperature regulating assembly, thereby adjusting the temperature of the food stored inside and controlling the rotation of the food tray assembly. The temperature regulating assembly is disposed near the food tray assembly and the controller, including... The device includes a thermoelectric cooler, a temperature conductive plate, a cooling block, a heat sink, and a cooling fan. The thermoelectric cooler is electrically connected to the controller and has a cooling side and a heating side, with the cooling side facing the cavity. The temperature conductive plate is located near the bottom of the food tray assembly. The cooling block is disposed between the cooling side of the thermoelectric cooler and the temperature conductive plate to conduct cold energy from the thermoelectric cooler to the temperature conductive plate. The heat sink is thermally connected to the heating side of the thermoelectric cooler. The cooling fan is positioned against the heat sink and has an air outlet facing the lower housing. The temperature conductive plate, the cooling block, the thermoelectric cooler, and the heat sink are connected by fasteners, and a heat-insulating gasket is provided on one side of the fastener.

[0006] Furthermore, the heat sink is a metal structure with multiple heat dissipation fins, and is fixed to the heating side of the semiconductor cooling chip by the fasteners, and the heat insulation gasket is located on one side of the heat sink.

[0007] Furthermore, the lower housing is provided with a mounting base, which includes a first mounting part, a second mounting part, and a third mounting part. The first mounting part is located at the center of the food tray assembly. The second mounting part is located near the side where the upper housing and the lower housing are rotatably connected and is used to mount the controller. The third mounting part is located near the second mounting part and is a hollow square columnar structure, which is used to fix the temperature regulating assembly.

[0008] Furthermore, the temperature regulating component also includes a first air guide and a second air guide. The first air guide and the second air guide are symmetrically arranged on both sides of the second mounting part, abutting against the lower housing, and together with the lower housing, forming an air outlet cavity.

[0009] Furthermore, the semiconductor cooling chip is surrounded by an insulation element, which is sandwiched between the first air guide and the second air guide, and is installed in close contact with the second mounting part, with the cooling block located inside the second mounting part.

[0010] Furthermore, both the first air guide and the second air guide include a first connecting portion, a second connecting portion, and a third connecting portion. The first connecting portion is fixedly attached to the mounting base; the second connecting portion is attached to the second heat insulation pad, which is disposed below the mounting base; and the third connecting portion abuts against the side of the semiconductor cooling chip.

[0011] Furthermore, the lower housing is provided with multiple air outlets corresponding to the cooling fan. The air outlets include a main air outlet facing the cooling fan and side air outlets on both sides of the cooling fan. The main air outlet and the side air outlets are located around the air outlet cavity formed by the first air guide, the second air guide, and the lower housing.

[0012] Furthermore, the pet feeder also includes a temperature detection component, which is connected to the controller.

[0013] Furthermore, the food tray assembly includes a support, multiple food trays, and a first driving component. The support has multiple spaced mounting holes. The multiple food trays are independent disc-shaped structures adapted to the size of the mounting holes and can be detachably installed on the mounting holes of the support, and are positioned close to the temperature conductive plate. The first driving component is electrically connected to the controller and is installed at the center below the support. The controller controls the support to rotate the food trays relative to the outer shell assembly through the first driving component.

[0014] Furthermore, the upper housing has a window, and the temperature regulating component also includes a heat-conducting plate. The heat-conducting plate has a notch, which corresponds to the size of one of the plates. The heat-conducting plate is installed at the notch and spaced apart from the heat-conducting plate. The area above the notch corresponds to the position of the window.

[0015] Compared with the prior art, the pet feeder provided by this utility model has the following significant advantages:

[0016] Highly efficient preservation and precise temperature control. Through a non-vertical stacked layout of the temperature regulation components, the cooling source (semiconductor cooling chip) and the cooling application end (bottom of the plate) are horizontally connected via a cooling guide block, effectively reducing the overall thickness of the equipment and achieving a compact structure. Simultaneously, this layout, combined with insulation design, reduces mutual interference between the hot and cold ends, improves cooling efficiency and temperature control uniformity, prevents localized overcooling or spoilage of food, and ensures long-lasting freshness.

[0017] Excellent heat dissipation and insulation performance. The optimized heat dissipation air duct design (including the main air outlet and side air outlet) and the setting of the first and second air guides ensure that the efficient heat generated by the heat dissipation module is quickly discharged to the outside of the equipment, while effectively isolating the heat dissipation area from the food preservation area, thus ensuring the insulation effect inside the cavity.

[0018] A thoughtful feeding experience. The unique heat-conducting plate design allows for localized heating of food in the designated dish before feeding, ensuring pets, especially during cold seasons, can enjoy food at a comfortable temperature, enhancing their eating experience and benefiting their health.

[0042] Please also refer to Figures 1 to 7 A pet feeder 100 includes a housing assembly 1, a temperature regulating assembly 2, a food tray assembly 3, and a controller 4. The temperature regulating assembly 2 and the food tray assembly 3 are both disposed inside the housing assembly 1. The controller 4 is embedded in the housing assembly 1. The operation panel 41 and the display screen 43 face the outside of the housing assembly 1. The controller 4 is internally provided with a circuit board 45 and wiring connected to the temperature regulating assembly 2 and the food tray assembly 3.

[0043] The outer casing assembly 1 supports the installation of other components and provides a sealed, insulated environment; the food tray assembly 3 stores food for pets; the temperature regulating assembly 2 regulates the temperature inside the outer casing assembly 1, thereby refrigerating the food inside the food tray assembly 3. The controller 4 controls the operating state of the temperature regulating assembly 2, thereby adjusting the temperature of the internally stored food and controlling the rotation of the food tray assembly 3.

[0044] The outer casing assembly 1 includes an upper casing 11 and a lower casing 13. A U-shaped connecting portion 111 is provided on one side of the upper casing 11, clamping both sides of the lower casing 13, allowing the upper casing 11 to rotate and open relative to the lower casing 13. A locking structure 15 and a push-button switch 17 are provided at the other end of the upper casing 11 and lower casing 13 opposite to the U-shaped connecting portion 111. The upper casing 11 and lower casing 13 can be spring-loaded apart by pressing the switch 17, or snapped together to form a cavity 101. To enhance the sealing effect, a sealing ring 19 can also be provided at the contact point between the upper casing 11 and the lower casing.

[0045] The control panel 41 and display screen 43 of the controller 4 are located in the middle area of ​​the U-shaped connecting part 111, maintaining the same horizontal plane as the upper housing 11. The connection between the upper housing 11 and the lower housing 13 is simple and convenient, and a mounting position for the controller 4 is reserved, ensuring that the controller 4 and the upper housing 11 are on the same horizontal plane, without forming any additional protrusions, making it convenient for storage. It should be noted that maintaining a uniform horizontal plane as described in this application does not mean an absolute flat plane; there may be slight height differences. However, for the sake of compact structure and ease of storage, there will generally not be a large height difference, at least within 5cm.

[0046] The food tray assembly 3 is installed in the cavity 101 and includes a bracket 31, a food tray 33 and a first driving member 35. The upper housing 11 includes a fixed food cover 112, a movable food cover 113 and a second driving member 114.

[0047] A window 115 is provided on the fixed food cover 112, and a movable food cover 113 is rotatably positioned relative to the fixed food cover 112. A second drive unit 114 is electrically connected to the controller 4. The movable food cover 113 can rotate and move relative to the fixed food cover 112 via the second drive unit 114, thereby blocking or opening the window 115. The window 115 is positioned relative to the food tray assembly 3 and corresponds to the size of the food tray 33. When the movable food cover 113 rotates to open the window 115, the pet can eat the food in the food tray assembly 3 through the window 115. The second drive unit 114 is electrically controlled via the controller 4. This setup can prevent irregular pet eating habits. Users can set parameters in the controller 4 according to the pet's eating habits to control the opening time of the window 115, ensuring reasonable control of the pet's eating time. Moreover, this setup prevents the food stored in each food tray 33 from being exposed to the air, effectively improving the refrigeration and insulation effect.

[0048] When food needs to be changed, manually press switch 17 to open the upper shell 11, allowing food to be placed into the food tray assembly 3; the operation is very convenient. After the food is stored, close the upper shell 11 to ensure effective isolation between the cavity 101 and the external environment. At the preset feeding time, control the second drive component 114 to open the movable food lid 113, and the pet can begin eating. A first heat insulation pad 116 is sandwiched inside the upper shell 11 to isolate the temperature inside the cavity 101 from the outside of the upper shell 11, further improving the refrigeration and insulation effect.

[0049] Please continue reading. Figure 5 and Figure 6The bracket 31 has a circular structure with multiple spaced mounting holes 311. The food trays 33 are multiple independent disc-shaped structures that can be installed on the mounting holes 311 of the bracket 31, and their size is adapted to the mounting holes 311. The first drive component 35 is installed at the center of the bottom of the bracket 31, controlling the bracket 31 to rotate the food trays 33, so that the multiple food trays 33 can correspond to the window 115 respectively, allowing the pet to eat food from different food trays 33 through the window 115. The first drive component 35 is controlled by the controller 4, which can effectively control the pet's eating. With this setting, the user can store food on each food tray 33 in advance and set the parameters of the controller 4. Through the coordinated rotation of the second drive component 114 and the first drive component 35, the user can control the pet's eating time and type, especially when the user is not at home, ensuring that the pet can eat a fixed amount of food at the designated feeding time.

[0050] In addition, the multiple independent plates 33 ensure that the plates 33 do not affect each other. On the one hand, their temperatures are not affected, and on the other hand, users can take out and put away food separately for cleaning or placing.

[0051] Please refer to the following: Figure 5 The bracket 31 is detachably connected to the lower housing 13 and the first drive member 35, facilitating removal, washing, and cleaning. At least two stepped grooves 312 are provided on the periphery of the bracket 31 near the protruding position above the first drive member 35. The size of the grooves 312 is approximately the same as the size of a human finger, allowing users to easily install and remove them using their fingers. Furthermore, the bracket 31 can be labeled with numbers 313 corresponding to different food dishes 33, allowing users to install the food according to the number 313. A controller 4 is then set to precisely control the rotation angle of the bracket 31, ensuring the pet eats the food from the food dish 33 according to a predetermined plan.

[0052] Please continue to refer to the following: Figure 6 , Figure 9 and Figure 10 The bracket 31 has a sidewall 314 around its periphery near the lower part of the first drive member 35, and at least two observation holes 315 with a preset spacing are provided on the sidewall 314. Correspondingly, the pet feeder 100 is also provided with a rotation detection component 6, which is set with the same preset spacing relative to the positions of the two observation holes 315, and is used to detect the rotation position of the bracket 31.

[0053] Specifically, the rotation position of the bracket 31 is determined by detecting whether it passes through two observation holes 315 during its rotation. This, combined with the identification number 313 on the bracket 31, is used to determine the unique installation position of the bracket 31. After the bracket 31 is installed, each food tray 33 is placed on the installation hole 311, food is placed in it, and the upper shell 11 is closed. To ensure that the food in all food trays 33 is kept refrigerated and warm, the controller 4 uses the first drive component 35 to control the bracket 31 to rotate continuously and at regular intervals for thorough refrigeration. When the pet needs to eat, the controller 4 uses the second drive component 114 to control the food lid to open the window 115. After the pet finishes eating, the food lid closes the window 115, and the controller 4 continues to rotate the bracket 31. When the pet eats again, the controller 4 uses the rotation detection component 6 to determine the rotation position of the bracket 31, and controls the bracket 31 to stop at the corresponding window 115 based on the position of the next number 313, so that the pet can accurately eat the food of the next number 313.

[0054] Please continue reading. Figure 3 , Figure 4 , Figure 7 and Figure 8 The temperature regulating component 2 is located near the food tray component 3 and the controller 4. The temperature regulating component 2 includes a semiconductor cooling chip 21, a cooling block 22, a temperature conduction plate 23, a heat sink 24, a cooling fan 25, and a heat conduction plate 26.

[0055] The cooling fan 25, heat sink 24, thermoelectric cooler 21, cooling block 22, and temperature conduction plate 23 are stacked and installed in sequence. The cooling fan 25 is positioned against the heat sink 24 facing the lower housing 13. The lower housing 13 has ventilation openings 131 corresponding to the cooling fan 25, including an air inlet 1311 facing the cooling fan 25 and air outlets 1313 on both sides of the cooling fan 25. The temperature conduction plate 23 is positioned near the bottom of the plate 33.

[0056] The thermoelectric cooler 21 includes a cooling side 211 and a heating side 213. The heating side 213 is attached to the heat sink 24, and the cooling side 211 is attached to the cooling block 22. The cooling block 22 is disposed between the cooling side 211 of the thermoelectric cooler 21 and the temperature conductive plate 23, and is used to conduct cold energy from the thermoelectric cooler 21 to the temperature conductive plate 23. Since the thermoelectric cooler 21 is a thin sheet structure, its cooling temperature is unstable. By setting the cooling block 22, the temperature of the thermoelectric cooler 21 can be concentrated in the cooling block 22 and then transferred to the temperature conductive plate 23, which can ensure a continuous cooling effect.

[0057] The controller 4 controls the cooling of one side of the semiconductor cooling chip 21, and transfers the temperature to the temperature conduction plate 23 through the cooling block 22, and then to the plate 33 through the temperature conduction plate 23, thereby controlling the temperature of the food in the plate 33.

[0058] Please refer to this carefully. Figure 7 and Figure 8 To ensure effective temperature transfer and prevent temperature interference between the cooling side 211 and the heating side 213, the temperature conduction plate 23, the cooling block 22, the thermoelectric cooler 21, and the heat sink 24 are connected by fasteners (not shown), with a heat insulation gasket 203 on one side of the fastener. Using fasteners instead of other structural supports ensures a tight, seamless fit between the temperature conduction plate 23, the cooling block 22, the thermoelectric cooler 21, and the heat sink 24, preventing temperature leakage and improving transfer efficiency. Furthermore, the heat insulation gasket 203 prevents the temperature from being neutralized at both ends of the cooling side 211 and the heating side 213 by the fasteners. The fasteners can be threaded or studded, and there can be one or more sets used in combination. The installation method can be from the cooling side 211 to the heating side 213 or vice versa; there are no restrictions.

[0059] In this embodiment, firstly, two fasteners are installed at intervals from one side of the heat sink 24. A heat insulation element 29 is fitted around the periphery of the thermoelectric cooler 21, passing through the heat sink 24 and the heat insulation element 29 before being threadedly connected to the cooling block 22. A heat insulation gasket 203 is provided on one side of the heat sink 24 to prevent heat transfer between the heat sink 24 and the cooling block 22 through the fasteners. Then, four fasteners are installed at intervals from one side of the temperature conduction plate 23, passing through the temperature conduction plate 23 before being threadedly connected to the cooling block 22. Since both the temperature conduction plate 23 and the cooling block 22 are located on the cooling side 211, there is no need to provide a heat insulation gasket 203 for isolation. Of course, in other embodiments, other methods can be selected to set the fasteners and heat insulation gaskets 203, which will not be described in detail here.

[0060] A notch 231 is formed in the temperature conductive plate 23, and the notch 231 corresponds to the size of a food dish 33. A heat-conducting plate 26 is installed at the notch 231, and the area above the notch 231 corresponds to the position of the window 115. The heat-conducting plate 26 is controlled by the controller 4 to dissipate heat and heat the food in the food dish 33 located below the window 115, thereby keeping the food in the food dish 33 at a low temperature and heating the food in the food dish 33 that the pet is about to eat, ensuring that the food is kept fresh while allowing the pet to eat heated food.

[0061] Please continue reading. Figure 3 , Figure 4 and Figures 9 to 11The lower housing 13 is provided with a mounting base 133, and a second heat insulation pad 135 is sandwiched under the mounting base 133. Together with the first heat insulation pad 116, they block the temperature outside the cavity 101 and the outer shell assembly 1, ensuring the preservation temperature of the food inside the cavity 101.

[0062] Mounting base 133 includes a first mounting part 1331, a second mounting part 1335 and a third mounting part 1333. The first mounting part 1331 is located at the center of the support 31 of the food tray assembly 3, forming a part that protrudes towards the support 31, and forms a mounting cavity 1301 with the second heat insulation pad 135. The first driving member 35 is located in the mounting cavity 1301 of the first mounting part 1331 and is connected to the support 31 through the first through hole 1303 on the first mounting part 1331, thereby controlling the rotation of the support 31.

[0063] Please refer to this carefully. Figure 11 To facilitate installation, the first mounting part 1331 features a boss structure 1302 extending towards the plate 33. A first through hole 1303 is formed on the upper surface of the boss structure 1302. The first driving component 35 includes a motor 351 and a transmission cover 353. The motor 351 is located inside the mounting cavity 1301 and drives the rotating core 355 through the first through hole 1303. The transmission cover 353 covers the outside of the boss structure 1302 and engages with the rotating core 355. The transmission cover 353 also engages with the bracket 31. The rotation detection component 6 is arranged around the lower periphery of the boss structure 1302, corresponding to the observation hole 315 on the bracket 31. Through the boss structure 1302 of the first mounting part 1331, the first driving component 35, the transmission cover 353, the bracket 31, and the rotation detection component 6 are relatively stably installed, effectively saving space in the internal cavity 101 of the outer shell assembly 1, while simultaneously meeting the functional requirements of rotation control and rotation angle monitoring of the bracket 31.

[0064] The second mounting portion 1335, located near the side where the upper housing 11 and the lower housing 13 are rotatably connected, forms a mounting space flush with the middle area of ​​the U-shaped connecting portion 111, for mounting the controller 4. The second mounting portion 1335 is also provided with a second through hole 1305 that rotatably connects with the upper housing 11. The upper housing 11 is clamped to both sides of the second mounting portion 1335 through the second through hole 1305, achieving a rotatable connection.

[0065] The third mounting part 1333 is located close to the second mounting part 1335. The third mounting part 1333 is a hollow square columnar structure, which is used to fix and install the temperature regulating component 2.

[0066] Please continue to refer to the following: Figure 4 , Figure 8 and Figure 12The temperature regulating component 2 also includes a first air guide 27 and a second air guide 28, which are symmetrically arranged on both sides of the second mounting portion 1335. A heat insulation component 29 is fitted around the periphery of the thermoelectric cooler 21 and sandwiched between the first air guide 27 and the second air guide 28, and is mounted flush with the third mounting portion 1333. A cooling block 22 is located within the third mounting portion 1333, with one side flush with the thermoelectric cooler 21 and the other side flush with the temperature conduction plate 23. This transfers the cooled temperature from the thermoelectric cooler 21 to the plate 33. Furthermore, the heat insulation component 29 and the third mounting portion 1333 better lock in the cold temperature emitted from the cooling side 211 of the thermoelectric cooler 21, preventing leakage.

[0067] The lower housing 13 is provided with multiple vents 131 corresponding to the cooling fan 25. The first air guide 27, the second air guide 28 and the semiconductor cooling chip 21 together with the lower housing 13 form an air outlet 137. The heat sink 24 is a metal structure with multiple heat sink fins, which is fixed to the heating side 213 of the semiconductor cooling chip 21 by fasteners. The cooling fan 25 is close to the heat sink 24 and is positioned relative to the vents 131 to exhaust the heat emitted by the semiconductor cooling chip 21 from the air outlet 1311 without affecting the internal temperature of the food tray assembly 3.

[0068] Both the first air guide 27 and the second air guide 28 include a first connecting portion 271, a second connecting portion 273, and a third connecting portion 275. The first connecting portion 271 is fixedly attached to the mounting base 133, the second connecting portion 273 is attached to the second heat insulation pad 135, and the third connecting portion 275 abuts against the side of the heat insulation member 29 around the semiconductor cooling chip 21. The air inlet 1311 and the air outlet 1313 are both located around the air outlet cavity 137 formed by the first air guide 27, the second air guide 28, and the lower housing 13. This allows the first air guide 27 and the second air guide 28 to clamp the semiconductor cooling chip 21 and block the air outlet cavity 137 from the cavity 101 where the food tray assembly 3 is located, preventing heat cross-contamination and improving the heat preservation effect. In addition, the second connecting portion 273 can also conduct the surrounding heat to the air outlets 1313 on both sides of the cooling fan 25, thereby increasing the heat dissipation efficiency.

[0069] The pet feeder 100 also includes a temperature detection component (not shown). The temperature detection component is connected to the controller 4 and is used to detect the external ambient temperature of the housing component 1 and the temperature of the air outlet cavity around the heat sink, thereby monitoring the heat dissipation. When the temperature inside the air outlet cavity is higher than the external temperature of the housing component 1 and exceeds a preset threshold, the controller will issue a warning message to remind the user that there is a heat dissipation problem.

[0070] Please refer to the following: Figure 13To ensure the cooling temperature inside the cavity 101, it is necessary to improve the sealing performance of the cavity 101. In this embodiment, in addition to the first heat insulation pad 116 and the second heat insulation pad 135, a third heat insulation pad 117 is also sandwiched inside the movable food cover 113. When the movable food cover 113 rotates relative to the fixed food cover 112 to the position of blocking the window 115, the third heat insulation pad 117 works together with the first heat insulation pad 116 and the second heat insulation pad 135 to ensure that the temperature inside the cavity 101 is isolated from the ambient temperature outside the outer shell assembly 1 and will not overflow through the window 115.

[0071] The bottom of the lower housing 13 is also equipped with multiple anti-slip pads 139, which allows the pet feeder 100 to be placed stably and in contact with the ground, preventing it from being easily kicked away by the pet and causing the food stored in the dish 33 to spill out.

[0072] Compared with the prior art, the pet feeder 100 provided in this application has the following significant advantages:

[0073] Highly efficient preservation and precise temperature control. Through the non-vertical stacking layout of the temperature regulation component 2, the cooling source (semiconductor cooling chip 21) and the cooling application end (bottom of the plate 33) are horizontally connected via the cooling guide block 22, effectively reducing the overall thickness of the equipment and achieving a compact structure. Simultaneously, this layout, combined with heat insulation design, reduces mutual interference between the hot and cold ends, improves cooling efficiency and temperature control uniformity, prevents localized overcooling or spoilage of food, and ensures long-lasting freshness.

[0074] Intelligent feeding management. By incorporating a rotatable multi-plate structure 33 and an openable / closable window 115, combined with precise control of the rotating food cover 113 and plates 33 by the controller 4, precise management of pet feeding time, portion size, and food type is achieved. Users can pre-set feeding plans, making it especially suitable for pet owners with busy work schedules or those who need to travel.

[0075] A thoughtful feeding experience. The unique heat-conducting plate 26 design can locally heat the food in the designated dish 33 before the pet eats, so that the pet, especially in cold seasons, can eat food at a suitable temperature, improving the pet's eating experience and benefiting the pet's health.

[0076] Independent refrigeration control and management. By setting up multiple independent plates 33, the plates 33 can avoid affecting each other. On the one hand, their individual temperatures are not affected, and on the other hand, users can take out and put away food separately for cleaning or placing.

[0077] Effective refrigeration temperature control. By setting the first heat insulation pad 116, the second heat insulation pad 135, and the third heat insulation pad 117 at the positions of the upper shell 11, the lower shell 13, and the movable food cover 113, the temperature inside the cavity 101 is isolated from the external ambient temperature of the outer shell assembly 1 as much as possible, thereby effectively controlling the refrigeration temperature.

[0078] Excellent heat dissipation and insulation performance. The optimized heat dissipation air duct design (including air inlet 1311 and air outlets 1313 on both sides) and the setting of the first air guide 27 and the second air guide 28 ensure that the efficient heat generated by the heat dissipation module is quickly discharged to the outside of the equipment, while effectively isolating the heat exchange between the heat dissipation area and the food preservation area, thus ensuring the insulation effect inside the cavity 101.

[0079] Convenient user operation. The controller 4 is integrated into the U-shaped connector 111 of the upper housing 11 and is flush with the surface of the housing, resulting in a simple appearance and easy operation. The upper housing 11 is opened and closed using a push-button buckle structure, which allows users to quickly open the feeder for food addition or cleaning and maintenance.

[0080] Please refer to the following: Figures 1 to 4 and Figure 14 This application also provides a pet feeder control method, in which the pet feeder 100 uses the method to cool the food in the cavity 101 and control the pet's eating, specifically including the following steps:

[0081] S1. Provide a housing assembly 1, which includes an upper housing 11 and a lower housing 13, and identify that the upper housing 11 and the lower housing 13 in the housing assembly 1 are fastened together to form a cavity 101;

[0082] S2. Provide a temperature regulating component 2, which includes a semiconductor cooling chip 21. The cooling side 211 of the semiconductor cooling chip 21 faces the cavity 101, and control the temperature regulating component 2 to cool the cavity 101.

[0083] S3. Provide a food tray assembly 3, which includes a support 31, multiple food trays 33 and a first driving component 35. The food trays 33 are detachably installed on the support 31. Control the first driving component 35 to drive the support 31 and the food trays 33 to rotate in a preset direction at a time.

[0084] S4. The upper housing 11 includes a fixed food cover 112 with a window 115, a movable food cover 113 and a second driving member 114. When the preset eating time is reached, the plate 33 is controlled to move to the position below the window 115, and the second driving member 114 is controlled to drive the movable food cover 113 to rotate and move relative to the fixed food cover 112 to open the window 115.

[0085] S5. After eating, control the second drive unit 114 to drive the movable food cover 113 to rotate and move relative to the fixed food cover 112, close the window 115, and continue to control the first drive unit 35 to drive the support 31 and the plate 33 to rotate at a time.

[0086] The pet feeder control method achieves refrigerated preservation of food stored in the cavity 101 by identifying and controlling the status of the outer shell assembly 1, temperature regulation assembly 2, and food tray assembly 3. Due to the spatial limitations of the thermoelectric cooler 21, the temperature decreases as it approaches the cooling point, while the temperature increases further away. In existing pet feeders, the food tray assembly 3 remains in a fixed position during the preservation phase, and rotation is only controlled when the pet needs to eat. This results in food stored further away from the thermoelectric cooler 21 typically being at a higher temperature and prone to spoilage. However, this method, by controlling the first drive component 35 to rotate the support 31 and the food tray 33 at regular intervals, ensures that all food stored in the cavity 101 reaches the cooling point, thereby guaranteeing a uniform refrigeration temperature and preventing food spoilage.

[0087] The timed rotation in S3 and S5 refers to the fact that after each plate 33 rotates to the position of the cooling point, it will stay for a certain period of time, such as about half an hour. This ensures sufficient cooling and preservation while saving power consumption of the first drive component 35. Of course, the dwell time is not limited and can be set as needed.

[0088] Please refer to the following: Figure 15 and Figure 16 Furthermore, to better ensure refrigeration effectiveness, S3 also includes the following steps:

[0089] S31. According to the pet's eating order, multiple food dishes 33 are numbered and installed sequentially in the first direction A circumferential direction. The food dishes 33 include a first feeding dish, a second feeding dish, and a third feeding dish; wherein, the first feeding dish is the first food dish 33 to be fed, the second feeding dish is the last food dish 33 to be fed, and the third feeding dish is the second to last food dish 33 to be fed.

[0090] S32. Set the preset optimal cooling point position, and control the first driving component 35 to drive the bracket 31 and the plate 33 to rotate, so that the second eating plate reaches the cooling point position.

[0091] S33. Set a first preset time, control the first driving component 35 to stop rotating, and after the first preset time, control the first driving component 35 to continue rotating along the first direction A until the third eating plate reaches the cooling point position.

[0092] S34. According to the first direction A and the first preset time, the first driving component 35 is continuously controlled to drive the bracket 31 and the plate 33 to rotate at a time.

[0093] It is important to note that, based on the above description, the thermoelectric cooler 21 has a sheet-like structure, with the cooling side 311 having the lowest temperature. Therefore, the cooling point location refers to the position of the plate 33 closest to the cooling side 311 of the thermoelectric cooler 21. Of course, depending on the number and position of the plates 33, there are two scenarios. First, a single plate 33 is located at the position closest to the thermoelectric cooler 21 as the cooling point location. Second, two plates 33 are symmetrically located at the positions closest to the thermoelectric cooler 21 as the cooling point locations. However, although there are two scenarios, they do not affect the pre-setting of the cooling point location or the arrival of the second and / or third serving plates at the cooling point location. In the second scenario, and the third serving plate is adjacent to the second serving plate, initially both the second and third serving plates arrive at the cooling point location simultaneously. In step S33, the third serving plate rotates to reach the original cooling point location of the second serving plate. This does not conflict with the above method; it is mainly used to confirm the rotation direction of the plates 33 and to explain the control method in detail.

[0094] The second serving plate, being the last plate used for eating, 33 must be kept for a longer period. Therefore, by numbering them sequentially and prioritizing the arrival of the second serving plate at the refrigeration point, the refrigeration effect of the second serving plate can be ensured. Continuing to rotate in the first direction A allows the plates 33 to arrive at the refrigeration point in reverse order, opposite to the eating sequence, thus ensuring that the last serving plate 33 is kept long enough until the time of eating, guaranteeing effective refrigeration.

[0095] Of course, in S34, when the first drive unit 35 drives the bracket 31 and the food tray 33 to rotate along the first direction A, so that the first food tray reaches the cooling point position, it continues to rotate along the first direction A to control the second food tray to reach the cooling point position again. That is to say, during the initial refrigeration process, before the pet's first feeding time of the day, the rotation is controlled along the first direction A, and each food tray 33 is controlled to reach the cooling point position in reverse order to ensure that the cooling temperature of each food tray 33 is more even.

[0096] To ensure the pet eats in a preset order, in S4, when the preset feeding time arrives, the food tray 33 is controlled to move to the position below window 115, including:

[0097] A rotation detection component 6 is provided to identify the rotational positions of the support 31 and the food tray 33, and to control the first drive component 35 according to the pet's feeding sequence, so that the food tray 33 corresponding to the feeding sequence number reaches below the window 115. At this time, the first drive component 35 is controlled to rotate directly, without the need for timed rotation, so that the next food tray 33 to be fed can be quickly and accurately placed below the window 115.

[0098] Please see Figure 17 To further improve refrigeration efficiency, in S5, the first drive unit 35 continues to control the timed rotation of the support 31 and the plate 33, including:

[0099] S51. Based on the number of plate 33 used in S3, determine the number of the fourth plate that was most recently used.

[0100] S52, control the first driving component 35 to drive the bracket 31 and the plate 33 to rotate, so that the second eating plate reaches the cooling point position;

[0101] S53. According to the first direction A and the first preset time, the first driving component 35 is continuously controlled to drive the bracket 31 and the plate 33 to rotate at a time until the fifth eating plate reaches the cooling point position and stops. The fifth eating plate is the plate 33 that will be used for the next eating relative to the fourth eating plate.

[0102] S54. Control the first driving component 35 to drive the bracket 31 and the plate 33 to rotate in the second direction B opposite to the first direction A, until the second eating plate reaches the cooling point position again and stops.

[0103] S55, control the first drive unit 35 to drive the bracket 31 and the plate 33 to rotate again along the first direction A, and repeat S53 and S54.

[0104] Since the pet has already eaten, there is no longer any food left between the second and fourth feeding dishes, so a good refrigeration effect is not needed. Therefore, continuing to control the first drive component 35 to rotate the bracket 31 and the dish 33 only needs to be done around the fifth feeding dish and the second feeding dish, which still contains food. By switching between rotation in the first direction A and the second direction B, it is ensured that the fifth feeding dish and the second feeding dish alternately reach the cooling point, effectively increasing the refrigeration effect while further saving energy consumption.

[0105] In S32 and S52, controlling the first drive unit 35 to rotate the bracket 31 and the plate 33 so that the second serving plate reaches the cooling point includes:

[0106] Based on the number of the fourth serving plate, the positional relationship between the fourth and second serving plates is determined, and the rotation direction is controlled to either direction A or direction B, ensuring that the second serving plate reaches the cooling point as quickly as possible. To ensure that the second serving plate reaches the cooling point first each time, after eating, the first drive unit 35 needs to be controlled to move the second serving plate to the cooling point as quickly as possible. At this time, either direction A or direction B can be selected for rotation control. However, to reduce power consumption and achieve the fastest possible arrival, by identifying the number of the fourth serving plate, the rotation position of plate 33 can be analyzed and calculated, and the optimal control scheme can be selected.

[0107] Similarly, in S4, after identifying the rotational positions of the support 31 and the plate 33, in order to make the plate 33 corresponding to the eating sequence number reach the bottom of the window 115 as quickly as possible, the first drive unit 35 can be controlled to rotate in the first direction A or the second direction B according to the rotational position information of the support 31 and the plate 33, so that the shortest rotational path can achieve the control purpose.

[0108] In this embodiment, the pet feeder control method further includes:

[0109] S6. When one of the following conditions is met, control the first drive unit 35 to stop rotating at a set time:

[0110] (1) Detect that the upper housing 11 and the lower housing 13 are in the open state;

[0111] (2) Only the second eating plate remains uneaten in the cavity 101 and the second eating plate has been rotated to the position of reaching the cooling point;

[0112] (3) Only the second and third eating plates remain uneaten in the cavity 101 and the second and third eating plates have rotated to the position of the cooling point.

[0113] By detecting the open and closed states of the upper housing 11 and the lower housing 13, the rotation of the first drive component 15 can be controlled to start or stop. This can also effectively reduce power consumption, and the rotation will not occur when the user replaces or cleans the plate 33 and the bracket 31.

[0114] Furthermore, when it is detected that only the second eating plate remains in the cavity 101 and the second eating plate has rotated to the position of reaching the cooling point, or when the second and third eating plates remain uneaten in the cavity 101 and the second and third eating plates have rotated to the position of reaching the cooling point, the drive is also stopped. It is only necessary to keep the last eating plate 33 in the cooling point position for refrigeration, so as to ensure the refrigeration effect while reducing the power consumption of the first drive unit 35.

[0115] It should be noted that the location of the cooling point is defined in this application, and the definition already indicates that there are two situations. Therefore, when determining whether to stop driving the first driving member 15 to rotate, it is necessary to consider the two situations of the plate 33 setting, so that this application can adapt to different plate 33 setting situations.

[0116] In this embodiment, the bracket 31 is made of plastic and has multiple spaced mounting holes 311. The multiple plates 33 are independent disc-shaped structures made of thermally conductive metal, adapted to the size of the mounting holes, and detachably mounted on the mounting holes 311 of the bracket 31. This design ensures that the temperature of each plate 33 is conducted without affecting each other.

[0117] To ensure that pets can eat heated food before mealtime, the temperature control component 2 also includes a heat-conducting plate 26. The heat-conducting plate 26 is positioned below the window 115 and close to the food dish 33. In step S4, before the preset feeding time arrives and the food dish 33 reaches the position below the window 115, the heat-conducting plate 26 is controlled to dissipate heat, heating the food in the food dish 33 located below the window 115. After being heated by the heat-conducting plate 26, the pet can eat food at a suitable temperature, rather than refrigerated food, which contributes to the pet's dietary health.

[0118] Finally, taking the five plates 33 set in this embodiment as an example, the above method will be briefly summarized and explained.

[0119] The five food trays 33 are numbered 1, 2, 3, 4, and 5 according to the pet's feeding order, with food placed on each tray 33. Specifically, tray 1 corresponds to the first feeding tray, tray 5 to the second feeding tray, and tray 4 to the third feeding tray. When the upper shell 11 and lower shell 13 are engaged to form a cavity 101, the first drive unit 35 is controlled to rotate the bracket 31 and the food trays 33 until the second feeding tray (tray 5) and the third feeding tray (tray 4) reach the cooling point. After a first preset time, such as half an hour, the rotation is controlled along the first direction A until the third feeding tray (tray 4) reaches the original cooling point position of tray 5, and the tray (tray 3) reaches the original cooling point position of tray 4. Thereafter, the food trays 33 are rotated to their cooling point positions every half hour.

[0120] Set a preset feeding time. Upon the first feeding time, control the first feeding tray (number 1) to move below window 115. After the pet finishes eating, rotate the second feeding tray (number 5) to the position where it reaches the cooling point, and then rotate it in the first direction (A) according to the timer control.

[0121] At this point, plate 1 is the fourth plate that has most recently finished eating, and plate 2 corresponds to the fifth plate. After the fifth plate (plate 2) rotates to the position where it reaches the cooling point, it stops rotating in the first direction (A) and starts rotating in the second direction (B), causing plate 3 (plate 33) to rotate to the position where it reaches the cooling point. This continues until the second plate (plate 5) rotates to the position where it reaches the cooling point, at which point it stops and then rotates in the opposite direction, starting in the first direction (A). Repeating these steps ensures that only plates 33 between 2 and 5 (plates 33 that have not yet been eaten) reach the cooling point, while plate 1 remains stationary.

[0122] After the pet has finished eating three times, the fourth feeding dish (numbered 3) corresponds to the one that was most recently finished. After this, dishes 33 numbered 1 through 3 no longer reach the cooling point; instead, dishes 33 numbered 4 and 5 directly reach the cooling point and stop rotating. When the upper housing 11 and lower housing 13 are detected to be in the open state, or when dishes 33 numbered 4 and 5 remain uneaten in the cavity 101 and have already rotated to the cooling point, the timed rotation of the first drive unit 35 is stopped, thereby reducing energy consumption.

[0123] Of course, each time before the preset feeding time arrives, and the food plate 33 reaches the position below the window 115, the heat-conducting plate 26 is controlled to dissipate heat to heat the food in the food plate 33 located below the window 115, ensuring that the pet eats at a suitable temperature and has a healthy diet.

[0124] Compared with the prior art, the pet feeder control method provided in this application has the following significant advantages:

[0125] Intelligent food preservation and uniform temperature control. By controlling the timed rotation of the food tray assembly 3, all trays 33 are rotated to the cooling point, achieving uniform cooling and preventing localized overheating that could lead to food spoilage. Compared to traditional static storage methods, this method significantly improves the overall food preservation effect and extends the shelf life of wet or perishable foods.

[0126] An energy-efficient refrigeration strategy. The method introduces an "on-demand rotation" and "directional dwell" mechanism, which drives the plate 33 to rotate only when necessary and dwells in a specific position for a preset time (such as half an hour). This ensures the refrigeration effect while significantly reducing the energy consumption of the motor 351 and improving the equipment's endurance.

[0127] Precise feeding sequence control and position recognition. Combining the rotation detection component 6 and the tray numbering system 33, the controller can accurately identify the position of each tray 33 and control it to precisely stop below the window 115 according to the preset feeding sequence. This enables precise management of pets' feeding time, amount, and type, making it especially suitable for pets with multiple meals or special dietary needs.

[0128] The system dynamically adjusts the refrigeration range to optimize energy consumption. After the pet has eaten, the system automatically identifies the food bowl 33 that has been eaten and dynamically reduces the refrigeration range, cooling only the uneaten food bowl 33 in rotation. This strategy ensures the freshness of leftover food while further reducing energy consumption and improving overall energy efficiency.

[0129] Flexible rotation direction control and path optimization. The controller intelligently selects the shortest rotation path (forward or reverse) based on the current position of the plate 33 and the target position, shortening the positioning time, reducing mechanical wear, and improving response speed and system lifespan.

[0130] The method provides a user-friendly interaction and maintenance experience. It integrates an opening / closing detection function, automatically pausing rotation when the upper casing is opened, allowing users to safely and conveniently add food or clean the plate, thus improving both the user experience and operational safety.

[0131] Intelligent feeding logic adaptable to multiple scenarios. Supports feeding plans with multiple food plates 33 and multiple time points. Users can flexibly set the feeding order and time of different food plates 33 to meet the diverse needs of pets in various scenarios such as daily feeding, holiday leave, or medical diet management.

[0132] On the other hand, the pet feeder provided in this application includes a controller and a computer program stored on the controller and executable thereon. When the controller executes the program, it implements the pet feeder control method.

[0133] In addition, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed, implements the pet feeder control method.

[0134] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
