[0039] 1 to 20 show a specific embodiment of the feeder proposed in this application.

[0040] In the embodiment of the present application, as shown in Figures 1 to 6, the feeder includes a shell 100, a metal liner 200, a semiconductor refrigeration sheet 300, a food bowl 400 and a first thermal insulation member 500. The shell 100 includes a first partition 110, which divides the interior of the shell 100 into a first chamber and a second chamber spaced apart in the vertical direction. The first partition 110 is formed with a first through hole 111. The metal liner 200 includes a main body 210 and a first boss 220 connected to each other. The main body 210 is provided with a first through hole 111. In the first chamber, the semiconductor refrigeration plate 300 has a cooling end 310 and a heating end 320 that are relatively arranged. The first boss portion 220 is connected to the cooling end 310 through the first through hole 111. The food bowl 400 is arranged in the first chamber. The metal liner 200 exchanges heat with the cooling end 310 and transfers the heat exchanged to the food bowl 400. The first thermal insulation component 500 is at least arranged between the first partition 110 and the plane where the semiconductor refrigeration plate 300 is located. The first thermal insulation component 500 is arranged around the first boss portion 220.

[0041] In this embodiment, the cooling end 310 of the semiconductor refrigeration plate 300 exchanges heat with the first chamber through the metal inner liner 200, which can reduce the temperature of the first chamber, thereby keeping the food in the food bowl 400 fresh; the first thermal insulation component 500 is arranged between the first partition 110 and the plane where the semiconductor refrigeration plate 300 is located, which can better block the heat transfer between the first chamber and the heating end 320, thereby prompting the cooling end 310 of the semiconductor refrigeration plate 300 to maintain a better cooling effect, thereby ensuring the refrigeration effect of the feeder.

[0042] It is understood that connection includes direct connection and indirect connection through an intermediary. In this embodiment, the first boss portion 220 is directly connected to the cooling end 310 through the first through hole 111. In other embodiments, the first boss portion 220 is connected to a metal heat transfer block through the first through hole 111, and the metal heat transfer block is connected to the cooling end 310. The metal heat transfer block can be an aluminum block, a copper block, or the like.

[0043] The present application is based on the following findings of the present applicant: in the prior art, the design of the feeder using a Peltier device for freshness preservation is unreasonable, and the temperatures of the cooling end 310 and the heating end 320 interfere with each other, which has a negative impact on the cooling capacity of the wet food feeder.

[0044] The technical solution of the embodiments of the present application overcomes the shortcomings of the prior art. Specifically, a housing 100 is formed around a chamber, and a first partition 110 is disposed within the chamber. The first partition 110 separates the chamber into a first chamber and a second chamber, with the first chamber being located above the second chamber and independent of the first chamber. The first and second chambers are connected via a first through hole 111 defined in the first partition 110. The semiconductor refrigeration plate 300 is arranged opposite to the first through hole 111, the metal inner liner 200 is located in the first chamber, and the first boss portion 220 of the metal inner liner 200 extends toward the second chamber and passes through the first through hole 111 to be connected to the refrigeration end 310, and performs heat exchange with the refrigeration end 310. The heat obtained by the heat exchange is transferred to the main body 210, and the main body 210 transfers the low temperature to the food bowl 400 through the first chamber, thereby achieving the effect of keeping the food in the food bowl 400 fresh; the first thermal insulation component 500 is arranged between the first partition 110 and the plane where the semiconductor refrigeration plate 300 is located, which can better block the heat transfer between the first chamber and the heating end 320, thereby prompting the refrigeration end 310 of the semiconductor refrigeration plate 300 to maintain a better cooling effect, thereby ensuring the refrigeration effect of the feeder.

[0045] It can be understood that the definition is: the plane between the cooling end 310 and the heating end 320 is the first plane; in this embodiment, the first thermal insulation component 500 is arranged between the first partition 110 and the first plane; in other embodiments, the first thermal insulation component 500 is arranged between the first partition 110 and the plane where the cooling end 310 is located, or the first thermal insulation component 500 is arranged between the first partition 110 and the plane where the heating end 320 is located.

[0046] As shown in Figure 1, the metal liner 200 is made of aluminum, a material with good thermal conductivity. The main body 210 and the first boss 220 of the metal liner 200 are integrally formed. The thickness of the main body 210 is the same as that of the first boss 220, ensuring effective heat transfer. The main body 210 extends over most of the bottom wall of the first chamber. The portion of the food bowl 400 facing the metal liner 200 receives the low temperature transmitted by the metal liner 200, thereby preserving food freshness. In practice, the first boss 220 can be formed directly on the metal liner 200 using a mold or by stamping.

[0047] As shown in Figure 1, the feeder includes a panel 112, which extends downward from the inner wall of the first through hole 111. The outer wall of the panel 112 is connected to the first thermal insulation component 500, and the inner wall of the panel 112 is connected to the first boss portion 220.

[0048] In this embodiment, the enclosure 112 is connected to the side of the first partition 110 facing away from the first chamber and is disposed circumferentially around the first through-hole 111. The enclosure 112 extends from the first through-hole 111 away from the first partition 110. In practice, the enclosure 112 and the first partition 110 are integrally formed. The inner circumferential wall of the enclosure 112 contacts the first boss 220, while the outer circumferential wall of the enclosure 112 is connected to the thermal insulation component to prevent the temperature of the first boss 220 from dissipating from the enclosure 112 to the surrounding area, thereby ensuring the cooling effect of the first boss 220.

[0049] In this embodiment, the bottom wall of the first boss portion 220 is connected to the cooling end 310, and the side wall of the first boss portion 220 is connected to the enclosure 112. Specifically, the metal liner 200 is disposed between the food bowl 400 and the first partition 110. The metal liner 200 is recessed from the side facing the food bowl 400 toward the second inner cavity. The first boss portion 220 is formed on the side of the metal liner 200 facing the first partition 110. The bottom of the first boss portion 220 is bonded to the cooling end 310 through the first through hole 111. The two can be bonded using thermally conductive adhesive. In this way, the cooling end 310 and the metal liner 200 are in direct contact and heat exchange, avoiding temperature loss caused by connection through an adapter, thereby improving cooling efficiency and cooling effect. The first boss portion 220 passes through the first through hole 111 so as to extend out of the first partition plate 110 . The sidewall of the first boss portion 220 is connected to the enclosure plate 112 to support the first boss portion 220 and prevent temperature loss of the first boss portion 220 .

[0050] As shown in Figure 1, the first partition 110 has a second through-hole 113, and the metal liner 200 covers the second through-hole 113. The first partition 110 is bonded to the metal liner 200. In a specific implementation, the metal liner 200 is connected to the first partition 110, which is made of plastic, and the two are fixedly connected using a "beer-in-beer" process. In this process, the metal liner 200 is placed upside down in a mold, with a portion of the mold resting on the metal liner 200. Then, injection molding material is poured into the mold. After this process is completed, the portion of the metal liner 200 abutted by the mold is not covered by the injection molding material, forming the aforementioned third through-hole 161. The "beer-in-beer" process secures the connection between the first partition 110 and the metal liner 200, effectively preventing condensation formed in the first chamber from entering the second chamber through the gap between the metal liner 200 and the first partition 110, thus providing a good seal.

[0051] As shown in Figure 2, the shell 100 also includes an outer tube 120, an inner tube 130, a top plate 140 and a bottom plate 150. The first partition plate 110 is connected to the inner circumferential wall of the inner tube 130, so that the first partition plate 110 and the inner tube 130 surround each other to form a first chamber. The top plate 140 is connected between the top end of the outer tube 120 and the top end of the inner tube 130, so that the top plate 140, the inner tube 130 and the outer tube 120 surround each other to form an annular cavity. The bottom plate 150 is connected to the bottom end of the outer tube 120, so that the outer tube 120, the first partition plate 110 and the bottom plate 150 surround each other to form a second chamber. The annular cavity is provided with a second thermal insulation component 510.

[0052] In this embodiment, the inner cylinder 130 is located within the space enclosed by the outer cylinder 120. The first partition 110 is located within the space enclosed by the inner cylinder 130 and is also connected to the inner circumferential wall of the inner cylinder 130. The first chamber is located within the space enclosed by the first partition 110 and the inner cylinder 130. The two side edges of the top plate 140 are respectively connected to the inner cylinder 130 and the outer cylinder 120, and the three surround and form an annular cavity. The bottom plate 150 is connected to the end of the outer cylinder 120 facing away from the top plate 140, and the bottom plate 150, the outer cylinder 120, and the first partition 110 surround and form a second chamber. The first thermal insulation member is located in the second chamber to prevent the heat in the second chamber from affecting the cooling effect of the first chamber. The second thermal insulation member 510 is disposed in the annular cavity to insulate the first chamber and further ensure the cooling and fresh-keeping effect of the first chamber. In addition, the first thermal insulation member 500 and the second thermal insulation member 510 are integrally molded to save processes and procedures.

[0053] As shown in Figure 1, the feeder also includes a second partition 160, which is arranged between the first partition 110 and the bottom plate 150. The second partition 160 is connected to the inner wall of the outer tube 120. The second partition 160 is provided with a third through hole 161, and the third through hole 161 is arranged corresponding to the heating end 320. The first thermal insulation component 500 is installed on the second partition 160.

[0054] In this embodiment, the second partition 160 is connected to the bottom plate 150 and the first partition 110, respectively. For example, the first partition 110 and the second partition 160 can be connected by screws passing through the first thermal insulation component 500. Of course, the screws can pass through the bottom plate 150 and then connect the first partition 110 and the second partition 160, respectively, to achieve a locked fixation of the three. The first thermal insulation component 500 is arranged in the space between the second partition 160 and the first partition 110 to prevent heat exchange between the second chamber and the first chamber, thereby ensuring the cooling effect of the first chamber. In the specific implementation process, the second partition 160 has a third through hole 161, and the heating end 320 is correspondingly arranged in the third through hole 161 and is connected to the second inner cavity through the third through hole 161.

[0055] As shown in Figure 1, the feeder also includes a heat dissipation component 700. A first groove 162 is formed on the side of the second partition 160 facing the bottom plate 150. The first groove 162 and the bottom plate 150 together form a heat dissipation duct 710. The heat dissipation component 700 is arranged in the heat dissipation duct 710 and is used to dissipate heat from the heating end 320.

[0056] In this embodiment, the heating end 320 is connected to a heat dissipation assembly 700, which dissipates heat generated by the heating end 320, preventing the hot air from being retained in the second chamber for a long time and affecting the cooling effect. In a specific implementation, the heat dissipation assembly 700 includes a radiator and a fan. The radiator is connected to the heating end 320 and exchanges heat with the heating end 320 to achieve the heat dissipation effect. The second partition 160 is recessed toward the first chamber on the side facing the bottom plate 150 to form a first groove 162. A heat dissipation duct 710 is formed between the first groove 162 and the bottom plate 150. An air inlet and an air outlet are provided on opposite sides of the housing 100. The fan generates a heat dissipation airflow in the heat dissipation duct 710. External air enters the heat dissipation duct 710 through the air inlet 7111 and is discharged through the air outlet 7121. The heat dissipation assembly 700 is located in the heat dissipation duct 710. The heat dissipation airflow passes through the radiator 730, removing heat from the surface of the radiator 730, achieving the heat dissipation effect. The low-temperature airflow entering from the air inlet 7111 takes away the heat of the radiator 730 after passing through the radiator 730, thereby increasing the temperature of the low-temperature airflow and forming a high-temperature airflow. Since the air inlet 7111 and the air outlet 7121 are arranged relative to each other, the high-temperature airflow formed by passing through the radiator 730 is directly discharged through the air outlet 7121 and will not stay in the second chamber for too long, thereby achieving a good heat dissipation effect.

[0057] As shown in FIG. 4 , the feeder further includes a first driving mechanism 800 for driving the food bowl 400 to rotate, and the first heat-insulating component 500 has a receiving cavity for receiving the first driving mechanism 800 .

[0058] As shown in Figure 4, the first thermal insulation member 500 is located between the second partition 160 and the first partition 110. The first thermal insulation member 500 is recessed toward the first chamber on the side of the first partition 110, forming a storage cavity on the side of the first thermal insulation member 500 facing the first partition 110. Simultaneously, the first thermal insulation member 500 protrudes toward the second chamber on the side facing the second chamber. Accordingly, the second partition 160 is recessed to form a receiving groove that accommodates the protruding portion of the first thermal insulation member 500. The first drive mechanism 800 drives the food bowl 400 to rotate within the first chamber. One end of the first drive mechanism 800 is located within the storage cavity, while the other end extends beyond the first partition 110 and connects to the bottom bowl to drive the food bowl 400 to rotate.

[0059] As shown in Figure 1, the first partition 110 has a fourth through hole 114, and the first driving mechanism 800 includes a first motor 810 and a first transmission member 820 that are connected to each other. The first motor 810 is arranged in the holding cavity, and the first transmission member 820 passes through the fourth through hole 114 into the first cavity. The first transmission member 820 is detachably connected to the food bowl 400; when the first transmission member 820 is connected to the food bowl 400, the first motor 810 drives the food bowl 400 to rotate.

[0060] The output shaft of the first motor 810 of the first drive mechanism 800 is connected to the first transmission member 820. One end of the first transmission member 820 passes through the fourth through hole 114 and is drivingly connected to the food bowl 400, and both are detachable. Specifically, one of the first transmission member 820 and the food bowl 400 is provided with a convex portion, and the other is provided with a concave portion. The convex and concave portions cooperate with each other to restrict the circumferential rotation of the first transmission member 820 and the food bowl 400. In this way, the rotation of the first transmission member 820 drives the rotation of the food bowl 400. If the food bowl 400 and the first transmission member 820 are connected by a spline, or if they are detachably plugged into each other, disassembly is convenient.

[0061] In this embodiment, the food bowl 400 is provided with a plurality of spaced troughs 410. Rotating the food bowl 400 allows the positions of the troughs 410 within the first chamber to be switched, thereby achieving the effect of refrigerating and preserving food in different troughs 410. It will be appreciated that the center of the food bowl 400 is connected to the first transmission member 820 to ensure stable rotation of the food bowl 400 driven by the first motor 810.

[0062] As shown in FIG. 1 , the first partition 110 includes a refrigeration zone 116 and a dining zone 115 . The area of ​​the refrigeration zone 116 is larger than that of the dining zone 115 . The metal liner 200 is disposed in the refrigeration zone 116 .

[0063] In this embodiment, the metal liner 200 is tightly connected to the first partition 110. Accordingly, the metal liner 200 is connected to the portion of the first partition 110 corresponding to the refrigeration zone 116, while the portion corresponding to the feeding zone 115 is not connected to the metal liner 200. In practice, when a pet consumes food in the portion of the food bowl 400 corresponding to the feeding zone 115, the portion of the food bowl 400 corresponding to the refrigeration zone 116 is kept cool, preserving the food in the bowl 400 and preventing spoilage. Furthermore, the food in the food bowl 400 corresponding to the trough 410 is heated and thawed as it is transferred to the feeding zone 115, making it easier for the pet to consume.

[0064] As shown in Figure 2, the housing 100 includes an upper cover 600, which covers the first chamber and is provided with a feeding port 610 connected to the first chamber. In a specific implementation, the upper cover 600 is located above the first chamber and is used to open and close the first chamber. When the first chamber is opened, food can be placed in the food bowl 400. When the first chamber is closed, the pet can consume the food on the food bowl 400 through the feeding port 610 of the upper cover 600. The feeding port 610 is arranged to correspond to the feeding area 115 of the first partition 110 to prevent the food from being too cold and affecting the pet's consumption. When the pet eats through the feeding port 610, the food in the trough 410 of the food bowl 400 located in the feeding area 115 is consumed. To maintain the cooling and freshness of the first chamber, the upper cover 600 also includes a door 620. After the pet stops eating, the door 620 closes the feeding port 610, preventing heat exchange between the first chamber and the outside world, which could cause the food to spoil. When the pet needs to eat, the door 620 opens the feeding port 610 to allow the pet to eat. As will be appreciated, the first drive mechanism 800 drives the food bowl 400 to rotate, switching between different troughs corresponding to the feeding port 610, allowing the pet to use different foods.

[0065] Heat dissipation components:

[0066] In this embodiment, as shown in Figures 7 to 10, the second partition 160 divides the second chamber into a third chamber and a fourth chamber separated along the upper and lower directions. The second thermal insulation component 510 is arranged in the third chamber. The second partition 160 is provided with a third through hole 161. The semiconductor refrigeration plate 300 is arranged corresponding to the third through hole 161. The heating end 320 faces the fourth chamber. The heat dissipation component 700 is arranged in the fourth chamber. A heat dissipation duct 710 is formed in the fourth chamber. The air inlet 7111 and the air outlet 7121 of the heat dissipation duct 710 are respectively provided on two opposite side walls of the fourth chamber. The heat dissipation component 700 is provided in the heat dissipation duct 710 and is used for heat dissipation at the heating end 320.

[0067] In this embodiment, the cooling end 310 of the semiconductor refrigeration plate 300 exchanges heat with the first chamber, which can reduce the temperature of the first chamber and thus keep the food in the food bowl 400 fresh; the heating end 320 faces the fourth chamber, which can reduce the heat transfer to the first chamber. At the same time, the air inlet 7111 and the air outlet 7121 of the heat dissipation duct 710 are relatively arranged so that the heat can be dissipated quickly and effectively to avoid heat backflow.

[0068] This application is based on the applicant's discovery that prior art feeders utilizing Peltier devices for fresh-keeping have the following design flaws: For example, in designs where air enters the housing through vents on the side of the housing, is drawn through heat sinks, and then exhausted through exhaust holes in the bottom of the housing, hot air cannot be quickly exhausted, at least due to the upward tendency of hot air. For example, in designs where the fresh-keeping compartment and heat-dissipating compartment are placed in front of each other, structural limitations require that the airflow, after passing through the heat sink, be diverted and exhausted through the outlet. During this process, the hot air flow is obstructed by corners and curves.

[0069] The technical solution of the embodiment of the present application overcomes the shortcomings of the prior art. Specifically, in this embodiment, the shell 100 has a second chamber, and the second chamber is divided by a second partition 160 to form a third chamber and a fourth chamber. The third chamber is above the fourth chamber and is interconnected through the third through hole 161 on the second partition 160. The food bowl 400 is located in the first chamber, and the cooling end 310 of the semiconductor refrigeration plate 300 is directed toward the first chamber through the third through hole 161 and reduces the temperature in the first chamber, thereby achieving a cooling effect and preserving the food in the food bowl 400. The heating end 320 of the semiconductor refrigeration plate 300 is directed toward the fourth chamber, and a heat dissipation component 700 is provided in the fourth chamber to dissipate heat from the semiconductor refrigeration plate 300, thereby achieving a heat dissipation effect. Specifically, the fourth chamber is formed with a heat dissipation duct 710, and the air inlet 7111 and the air outlet 7121 are arranged opposite to each other and opened on two opposite side walls of the fourth chamber. In this way, a heat dissipation airflow is formed from the air inlet 7111 to the air outlet 7121, and the heat dissipation component 700 is connected to the heating end 320 and performs heat exchange with the heating end 320. The heat dissipation airflow flows from the air inlet 7111 to the air outlet 7121 and passes through the heat dissipation component 700 to take away the heat of the heat dissipation component 700, thereby dissipating the heat of the heating end 320.

[0070] A first groove 162 is formed on one side of the second partition plate 160 facing the fourth chamber, and the first groove 162 and the bottom wall of the fourth chamber together form a heat dissipation duct 710. The structure of this embodiment is simple.

[0071] As shown in FIG8 , heat dissipation assembly 700 includes fan 720. Heat dissipation duct 710 includes inlet duct 711 and outlet duct 712. Inlet 7111 and the air inlet side of fan 720 communicate with inlet duct 711. Outlet 7121 and the air outlet side of fan 720 communicate with outlet duct 712. The flow area of ​​at least one section of outlet duct 712 gradually increases along outlet 7121. This embodiment effectively improves the efficiency of heat dissipation airflow out of outlet 7121, speeding up the airflow discharge rate and thereby improving heat dissipation efficiency.

[0072] In a specific implementation, the air inlet duct 711 and the air outlet duct 712 form the heat dissipation duct 710. It is understood that the portion between the air inlet side of the fan 720 and the air inlet 7111 is the air inlet duct 711, and the portion between the air outlet side of the fan 720 and the air outlet 7121 is the air outlet duct 712. Under the action of the fan 720, external air enters the air inlet duct 711 from the air inlet 7111, passes through the fan 720, enters the air outlet duct 712, and is finally discharged from the air outlet 7121.

[0073] It is understandable that the portion of the heat dissipation component 700 that contacts the heating end 320 can be located in the air inlet duct 711 or in the air outlet duct 712. Of course, in order to ensure the heat dissipation effect, it is preferred to locate the heat dissipation component 700 in the air outlet duct 712.

[0074] It is understood that the specific methods for achieving "the flow area of ​​at least a section of the air outlet duct 712 gradually increases along the direction of the air outlet 7121" include at least the following methods. Method 1: As shown in Figure 9, the bottom wall of the first groove 162 has a first inclined portion 713, which is inclined upward toward the bottom wall surface away from the fourth chamber. Method 2: As shown in Figure 9, the side wall of the first groove 162 has a second inclined portion 714, which is inclined outward toward the air outlet 7121.

[0075] In a specific implementation process, the air outlet duct 712 may be provided with only the first inclined portion 713 , or only the second inclined portion 714 , or both.

[0076] As shown in Figure 8, the flow area of ​​at least one section of the air inlet duct 711 gradually increases along the direction of the air inlet 7111. In this embodiment, the cross-sectional area of ​​the air duct section near the fan 720 is smaller, which can increase the speed and pressure of the airflow at this location, providing sufficient thrust for the hot air flow to overcome the resistance of the entire air duct system and maintain good air circulation and fluidity.

[0077] In this embodiment, the cross-sectional area of ​​the outlet duct 712 increases near the outlet 7121, while the cross-sectional area of ​​the inlet duct 711 decreases near the fan 720. Since the airflow gradually converges from a large cross-sectional area to a small cross-sectional area in the inlet duct 711, the airflow velocity increases and the thrust is enhanced, creating a stronger convection effect within the heat sink 730. Since the outlet 7121 is the final outlet for the airflow, the duct section with a larger cross-sectional area of ​​the outlet duct 712 allows more hot air to pass through and contact the outlet 7121, thereby effectively discharging heat from the housing 100.

[0078] As shown in Figure 7, the heat dissipation assembly 700 includes a heat sink 730, which includes a heat conductive base 732 and a plurality of heat dissipation fins 731. The heat conductive base 732 is connected to the heating end 320. The plurality of heat dissipation fins 731 are distributed at intervals on the heat conductive base 732. A heat dissipation channel is formed between two adjacent heat dissipation fins 731. The extension direction of the heat dissipation channel is the same as the extension direction of the heat dissipation duct 710.

[0079] During the specific implementation process, the heat-conducting base 732 and the heat-dissipating fins 731 are both made of metal materials with good heat conduction efficiency, and the two can be an integrally formed structure. One side of the heat-conducting base 732 is connected to the heating end 320 by bonding or bolting, and the heat-conducting base 732 exchanges heat with the heating end 320 of the semiconductor refrigeration plate 300. A plurality of spaced heat-dissipating fins 731 are provided on the other side of the heat-conducting base 732, and heat is further transferred to the heat sink. The heat-dissipating fins 731 are spaced apart on the heat-conducting base 732, and a heat dissipation channel is formed between adjacent heat-dissipating fins 731. After passing through the heat-dissipating channel, the heat-dissipating airflow takes away the heat on the surface of the heat-dissipating fins 731, thereby achieving the heat dissipation effect. The extension direction of the heat-dissipating channel is the same as the extension direction of the heat-dissipating air duct 710, that is, the heat-dissipating channel is provided in parallel with the heat-dissipating air duct 710. The heat-dissipating airflow can quickly pass through the heat-dissipating channel and take away the heat from the heat-dissipating fins 731 and the heat-dissipating base 732, further improving the heat dissipation efficiency.

[0080] As shown in FIG7 , the heat dissipation fins 731 include inner fins 7311 and outer fins 7312 . The outer fins 7312 are provided on both sides of the inner fins 7311 . The thickness of the outer fins 7312 is greater than that of the inner fins 7311 . This embodiment can increase the strength of the heat sink 730 .

[0081] In this embodiment, the distance between adjacent inner fins 7311 is 6 mm. Compared to a densely packed arrangement of fins 731, this allows for faster airflow through the heat dissipation channel, improving heat dissipation efficiency. The thickness of the inner fins 7311 is thinner than that of the outer fins 7312. Thinner inner fins 7311 provide greater heat dissipation efficiency, while thicker outer fins 7312 enhance the strength of the heat sink 730.

[0082] In some embodiments, a mounting channel is formed between the outer fin 7312 and the adjacent inner fin 7311 , and screws pass through the mounting channel through the heat conductive base 732 to connect to the second partition plate 160 .

[0083] In another embodiment, a mounting channel is formed between the heat dissipation fins 731 . The mounting channel is perpendicular to the heat dissipation channel. Screws pass through the heat conductive base 732 from the mounting channel to connect to the second partition plate 160 .

[0084] Optionally, a standard point is defined on the outlet surface of the fan 720 in the vertical direction. The distance between the standard point and the top of the outlet surface is 1 / 3 of the outlet surface's vertical height. The ends of the heat dissipating fins 731 that contact the heat conductive base 732 are located at the same level as the standard point. To ensure effective heat dissipation, the outlet surface of the fan 720 passes over the heat dissipating fins 731 as much as possible. In this embodiment, the tops of the heat dissipating fins 731, i.e., the ends where the heat dissipating fins 731 connect to the heat conductive base 732, are located at 1 / 3 of the outlet surface's vertical height. This allows the heat dissipating airflow to pass over the majority of the radiator 730, improving heat dissipation efficiency.

[0085] As shown in FIG7 , the bottom wall of the first groove 162 is provided with a second groove 163, and the third through hole 161 is provided in the bottom wall of the second groove 163. A second boss portion 7321 is formed on the surface of the heat conductive base 732 facing the second partition plate 160. The second boss portion 7321 is embedded in the second groove 163 to connect with the heating end 320. In this embodiment, the connection between the second boss portion 7321 and the heating end 320 forms a close thermal conductive contact, promoting heat transfer between the heating end 320 and the heat conductive base 732.

[0086] As shown in FIG10 , a third groove 164 is formed on the side of the second partition 160 facing the first chamber. The feeder further includes a first drive mechanism 800 for rotating the food bowl 400. The first drive mechanism 800 is at least partially disposed within the third groove 164. This embodiment facilitates miniaturization of the overall structure of the feeder.

[0087] During implementation, the third groove 164 is recessed from the side of the second partition 160 facing the first chamber toward the fourth chamber. The food bowl 400 is located within the first chamber, and a first drive mechanism 800 is disposed between the food bowl 400 and the second partition 160. The first drive mechanism 800 drives the food bowl 400 to rotate within the first chamber. Furthermore, the first drive mechanism 800 includes a first motor 810, the output shaft of which is drivably connected to the food bowl 400. The food bowl 400 is formed with a plurality of food troughs 410 for placing food. The position of the food troughs 410 is changed by the rotation of the food bowl 400. The housing 100 is provided with a feeding port 610, which is connected to the first chamber. The pet consumes food from the food bowl 400 through the feeding port 610. By rotating the food bowl 400, the pet can select food from different food troughs 410 through the feeding port 610 provided in the housing 100.

[0088] To prevent pets from touching the internal structure of the housing 100 or from being injured by components such as the fan 720 and radiator 730 within the housing 100, as shown in FIG7 , the heat dissipation assembly 700 includes an air inlet frame 121 and an air outlet frame 122. The air inlet frame 121 is mounted at the air inlet 7111, and the air outlet frame 122 is mounted at the air outlet 7121. Furthermore, the arrangement of the air inlet frame 121 and the air outlet frame 122 prevents debris from entering the heat dissipation duct 710 and causing damage.

[0089] In a specific implementation process, the air inlet 7111 and the air outlet 7121 are opened on both side walls of the shell 100 , and the air inlet frame 121 and the air outlet frame 122 are respectively connected to the shell 100 .

[0090] Door panel removal:

[0091] In the technical solution of the present application, as shown in Figures 11 to 20, the feeder includes a base, an upper cover 600, a second drive mechanism 900, a door body 620 and a locking mechanism. The base defines a receiving cavity with a top opening, the upper cover 600 is covered on the base, and the upper cover 600 is provided with a feeding port 610 communicating with the receiving cavity. The second drive mechanism 900 is installed on the upper cover 600, and the second drive mechanism 900 has a positioning portion 910. The door body 620 is detachably connected to the positioning portion 910. When the door body 620 is connected to the second drive mechanism 900, the second drive mechanism 900 The door body 620 is driven to rotate to open or close the feeding port 610. The second driving mechanism 900 is connected to the locking mechanism to drive the locking mechanism to rotate. The locking mechanism includes a locking member 920 and a reset member 930. The door body 620 has a clamping portion 621 detachably connected to the locking member 920. The locking member 920 can move between a locked position that cooperates with the clamping portion 621 and an unlocked position that disengages from the clamping portion 621. The reset member 930 is connected to the locking member 920. The reset member 930 applies an elastic reset force to the locking member 920 to move from the unlocked position to the locked position.

[0092] In this embodiment, when the door body 620 needs to be removed, the user first moves the locking piece 920 to the unlocking position so that the door body 620 and the locking mechanism are unlocked, and then removes the door body 620 from the positioning portion 910 of the second drive mechanism 900. The user can clean the door body 620 after removing the door body 620; when the user needs to install the door body 620 on the upper cover 600, the user first connects and positions the door body 620 and the second drive mechanism 900 through the positioning portion 910, and then moves the locking piece 920 to the locking position so that the locking mechanism locks the door body 620, so that the door body 620 can be quickly installed; when the second drive mechanism 900 is in motion, the door body 620 and the locking mechanism connected to the second drive mechanism 900 rotate synchronously.

[0093] As shown in Figures 16-18 , in this embodiment, a feeding port 610 extends through the upper cover 600. A food container is placed in the base, and the upper cover 600 covers the base. The pet consumes the food in the container through the feeding port 610. The outline and shape of the feeding port 610 are not limited in this embodiment; the size of the feeding port 610 can accommodate most pets or be customized to suit different pets. A door 620 is rotatably connected to the upper cover 600 and is connected to a second drive mechanism 900. The second drive mechanism 900 rotates the door 620 to open and close the feeding port 610. When the pet needs to eat, the second drive mechanism 900 rotates the door 620 to open the feeding port 610, allowing the pet to consume the food in the container through the feeding port 610. When the pet finishes eating, the second drive mechanism 900 rotates the door 620 in the opposite direction to close the feeding port 610, preventing the food from being exposed to the environment for extended periods, potentially contaminating it and attracting flies and insects.

[0094] 13-14 , the second drive mechanism 900 also drives the locking mechanism to rotate, and the locking mechanism rotates synchronously with the door body 620. The locking mechanism includes a locking member 920 and a reset member 930. The door body 620 has a snap-fit ​​portion 621 that is detachably connected to the locking member 920, so that the locking member 920 has a locked position and an unlocked position. Specifically, when the locking member 920 is in the locked position, the locking member 920 cooperates with the clamping portion 621 to connect the locking member 920 to the door body 620, and the door body 620 rotates to open or close the feeding port 610 under the drive of the second drive mechanism 900; when the locking member 920 is in the unlocked position, the locking member 920 can be disengaged from the clamping portion 621, and then the door body 620 is disengaged from the locking member 920, and the door body 620 can further be disengaged from the positioning portion 910 of the second drive mechanism 900, so that the door body 620 can be disassembled and cleaned. When the door body 620 needs to be installed, the door body 620 is first connected to the second drive mechanism 900 through the positioning portion 910 to achieve positioning, and then the locking member 920 is moved to the locked position so that the locking mechanism locks the door body 620, so that the door body 620 can be installed quickly and conveniently. The reciprocating movement of the locking member 920 allows the locking member 920 to reciprocate between the locked position and the unlocked position. The locking mechanism further includes a reset member 930, which is connected to the locking member 920 and applies an elastic reset force to the locking member 920 to move from the unlocked position to the locked position. In addition, it is understood that the door body 620 is provided with a component that cooperates with the positioning portion 910. The two cooperate to achieve the positioning and connection of the door body 620, so that the second driving mechanism 900 can drive the door body 620 to rotate.

[0095] As shown in Figure 15, the second transmission member 940 has a protrusion formed on the surface closest to the door body 620. This protrusion serves as a positioning portion 910. The door body 620 has a fifth through-hole 623, into which the protrusion engages. The second transmission member 940 also drives the door body 620 to rotate by engaging the protrusion in the fifth through-hole 623. When installing the door panel on the upper cover 600, the user first engages the protrusion in the fifth through-hole 623 to connect and position it, and then installs the locking mechanism. The positioning portion 910 facilitates the positioning and installation of the door body 620, ensuring that the feeding port 610 can be accurately opened and closed during the rotation of the door body 620.

[0096] In a specific implementation, the protrusion mates with the fifth through hole 623 and can be integrally formed with the second transmission member 940 to enhance the strength of the positioning portion 910. Alternatively, the protrusion can be formed by recessing the side of the second transmission member 940 facing away from the door body 620 toward the door body 620, thereby forming a protrusion on the opposite side of the second transmission member 940. The cross-section of the protrusion and the fifth through hole 623 can be circular, square, or any other shape, not limited to this in this embodiment, as long as the two mate.

[0097] In another embodiment, the second transmission member 940 is provided with a fifth through hole, the door body 620 is provided with a protrusion, the fifth through hole is a positioning portion, and the protrusion is embedded in the fifth through hole, which can also realize driving the door body 620 to rotate. Please refer to the above embodiment and will not be described in detail here.

[0098] As shown in Figure 12, the second driving mechanism 900 includes a second motor 950 and a second transmission member 940. One end of the second transmission member 940 is fixedly connected to the motor shaft of the second motor 950, and the other end of the second transmission member 940 is detachably connected to the door body 620. In the specific implementation process, the second motor 950 is installed on the upper cover 600, the motor shaft of the second motor 950 is connected to the second transmission member 940, and the door body 620 is driven to rotate through the second transmission member 940. Specifically, the second transmission member 940 may be provided with a fixing hole, and the motor shaft of the second motor 950 is inserted into the fixing hole. It is understandable that a driving surface is formed between the motor shaft and the fixing hole, and the motor shaft is driven and connected to the second transmission member 940 through the driving surface, and drives the second transmission member 940 to rotate, thereby driving the door body 620 to rotate. It is understandable that the fixing hole can be a blind hole or a through hole.

[0099] As shown in Figures 13-14, the locking member 920 has a hook portion 921. The door body 620 has a sixth through hole, which serves as the engaging portion 621. In the locked position, the hook portion 921 passes through the sixth through hole and engages with the side of the door body 620 facing away from the upper cover 600. Specifically, the locking member 920 is connected to the second drive mechanism 900, and the hook portion 921 of the locking member 920 engages with the door body 620, thereby enabling the locking member 920 to be removable from the door body 620. The hook portion 921 is provided with a hook. When the locking member 920 is in the locked position, the hook 410 extends from the sixth through hole to the side of the door body 620 facing away from the upper cover 600 and engages with the door body 620. To disassemble, the hook portion 921 is driven toward the unlocked position, moving the hook portion 921 away from the locked position, and then separating the hook portion 921 from the sixth through hole. In this way, the door body 620 is detachably connected to the locking member 920 and the second transmission member 940, so that the door body 620 is easily disassembled by being engaged with the hook portion 921 and the second motor 950 driving the door body 620 to rotate through the second transmission member 940.

[0100] As shown in Figure 12, the second transmission member 940 includes a cylindrical portion 941, the cylindrical portion 941 includes a bottom wall and a side wall extending from the edge of the bottom wall in a direction away from the bottom wall, the bottom wall is provided with a mounting hole, the locking member 920 has a fixing portion 922, the fixing portion 922 is connected to the hook portion 921, the fixing portion 922 is provided in the accommodating space enclosed by the side wall and the bottom wall, and the hook portion 921 extends out of the accommodating space from the mounting hole.

[0101] As shown in Figure 15, one end of the reset member 930 is connected to the fixed portion 922, and the other end of the reset member 930 is connected to the cylindrical portion 941. In a specific implementation, the reset member 930 is an elastic element, and the elasticity imparts elastic force to the fixed portion 922, allowing the hook portion 921 to firmly engage the door body 620. In this embodiment, the reset member 930 is a spring, one end of which abuts the inner wall of the accommodating space and the other end abuts the fixed portion 922, so that the fixed portion 922 is closely attached to the inner wall of the accommodating space, thereby causing the hook portion 921 to abut the side wall of the sixth through hole, ensuring the effective engagement of the hook portion 921 with the door body 620.

[0102] As shown in FIG12 , the feeder further includes a pressure plate 960 disposed within the accommodating space. The pressure plate 960 has a through hole for the motor shaft of the second motor 950 to pass through. The pressure plate 960 is disposed at the top of the fixing portion 922 . The pressure plate 960 is fixedly connected to the second transmission member 940 , such as by screws. The side of the pressure plate 960 facing the accommodating space constrains the fixing portion 922 and the reset member 930 .

[0103] As shown in Figure 12, the upper cover 600 is fixedly installed with a sleeve 970, which is sleeved on the outer peripheral wall of the cylindrical portion 941; the outer wall of the cylindrical portion 941 of the second transmission member 940 is rotatably connected to the connecting hole 681 of the upper cover 600 through the sleeve 970 to protect the upper cover 600 and avoid wear when the second transmission member 940 rotates.

[0104] As shown in Figure 15, the second transmission member 940 includes a sensing portion 942, which extends from the circumferential edge of the cylindrical portion 941 in a direction away from the cylindrical portion 941. The feeder also includes a sensing switch 943, which is communicated with the second motor 950. The sensing switch 943 is used to detect the sensing portion 942 to generate a control signal. The sensing portion 942 includes two circumferentially spaced notches. The sensing switch 943 is a photoelectric switch. The central angle formed between the two notches is the same as the rotation range angle of the door body 620.

[0105] During the specific implementation process, the sensing portion 942 is arranged at one end of the cylindrical portion 941 away from the door body 620, and extends along the circumferential edge of the cylindrical portion 941 in a direction away from the cylindrical portion 941, and is provided with two notches, which are spaced circumferentially. In this embodiment, the sensing switch 943 is connected to the second motor 950 for communication, and the sensing switch 943 is used to detect the position of the door body 620 to achieve the rotational positioning of the door body 620. It is understandable that the sensing switch 943 includes a transmitting end and a receiving end, and the transmitting end and the receiving end are spaced apart. The sensing portion 942 rotates in the space between the transmitting end and the receiving end. When the notch rotates to the space, the light emitted by the transmitting end is received by the receiving end, and a control signal is generated. The second motor 950 stops the action according to the control signal, thereby placing the door body 620 in an open or closed state.

[0106] As shown in Figures 16-18, the upper cover 600 is provided with a first stopper 651 and a second stopper 652 spaced apart on the side facing the accommodating cavity. When the door 620 fully closes the feeding port 610, the door 620 abuts the first stopper 651. When the door 620 fully opens the feeding port 610, the door 620 abuts the second stopper 652. The first stopper 651 and the second stopper 652 are integrally formed with the upper cover 600 and serve to limit the rotational position of the door 620, preventing it from excessive rotation.

[0107] Specifically, in one embodiment, the upper cover 600 has a plurality of protrusions on its surface facing the accommodating cavity, which are a first limiting portion 651 and a second limiting portion 652. The door body 620 rotates between the two protrusions and abuts against the sidewall of the corresponding protrusion when rotating to a corresponding position.

[0108] In another embodiment, as shown in FIG19 , a fourth groove 650 is provided on the side of the upper cover 600 facing the accommodating cavity. The door body 620 moves within the fourth groove 650. The fourth groove 650 is within the range of movement of the door body. The groove walls where the fourth groove 650 abuts against the door body 620 are respectively a first limiting portion 651 and a second limiting portion 652. In this embodiment, the door body 620 reciprocates within the fourth groove 650. The two groove walls of the fourth groove 650 form the first limiting portion 651 and the second limiting portion 652, which limit the rotation range of the door body 620.

[0109] As shown in Figure 16, the feeder includes a first driving mechanism 800 and a food bowl 400 arranged in the accommodating cavity. The food bowl 400 has a plurality of food troughs 410 for accommodating food. The first driving mechanism 800 is installed on the base. The first driving mechanism 800 drives the food bowl 400 to rotate so that at least one of the food troughs 410 is exposed to the feeding port 610.

[0110] In this embodiment, the first drive mechanism 800 drives the food bowl 400 to rotate circumferentially. To ensure smooth rotation and coordination between the food bowl 400 and the door 620, the rotation axis is the central axis of the food bowl 400. One side of the food bowl 400 is recessed to form a food trough 410. In this embodiment, the food bowl 400 includes multiple spaced-apart food troughs 410. When the feeding port 610 is open, the food trough 410 communicates with the outside world through the feeding port 610, allowing the pet to consume food from the trough 410. In this embodiment, the food bowl 400 can be rotated to switch between different food troughs 410 and the feeding port 610. If the user places different foods in different food troughs 410, the pet can consume different foods from different food troughs 410 through the same feeding port 610, increasing the variety of food available to the pet fish. If different food troughs 410 are set to rotate to the feeding area 115 at different times, automatic feeding can be implemented at different times.

[0111] As shown in Figures 16-18, the center of the food bowl 400 is recessed away from the upper cover 600 to form an escape groove 420. When the upper cover 600 is closed on the base, the end of the locking member 920 away from the upper cover 600 is located in the escape groove 420. Because the locking member 920 rotates synchronously with the door body 620 under the drive of the second motor 950, the food bowl 400 rotates circumferentially under the drive of the first drive mechanism 800. When the upper cover 600 is closed on the base, the end of the locking member 920 away from the upper cover 600 is located in the escape groove 420, without affecting the rotation of the door body.

[0112] As shown in FIG. 12 , in order to seal the door 620 and the upper cover 600 to prevent a gap from forming between the door 620 and the upper cover 600 so as to allow flies and insects to pass through and enter the food bowl 400 , the door 620 is provided with a first sealing member 660 in contact with the upper cover 600 .
