Pet feeder

Abstract

This utility model relates to the field of pet supplies technology, and in particular to a pet feeder. The pet feeder of this utility model has a first magnetic suction component at the top of the drive shaft, and a connecting hole at the center of the turntable near the base. A second magnetic suction component is installed inside the connecting hole. When the drive shaft is inserted into the connecting hole, the first and second magnetic suction components are magnetically connected. When the motor starts, the drive shaft and the connecting hole work together to drive the turntable to rotate synchronously, achieving power transmission. Centrifugal force acts on the food on the turntable, causing the food to move towards the edge of the turntable and finally flow out through the food outlet. The first and second magnetic suction components ensure that the drive shaft is tightly attached to the connecting hole, preventing axial disengagement due to vibration or other factors during rotation. Overcoming the magnetic attraction allows for quick separation of the turntable from the base, facilitating separate cleaning of the turntable and the inside of the food storage chamber. This prevents food residue from accumulating and breeding bacteria, and also avoids the risk of food debris and moisture corroding the drive motor and other electrical components.

Description

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

[0002] With the trend of intelligent development of pet products, turntable feeders have become the choice of many pet owners due to their features such as quantitative food distribution, convenient operation, and strong interactivity.

[0003] However, since the turntable parts come into direct contact with food, bacteria can easily grow after long-term use, affecting the hygiene of pets' diets. Therefore, regular and thorough cleaning is necessary. However, the connection between the turntable and the drive unit is often a fixed or complex nested design. Because the drive unit contains electrical components such as motors and circuits, it is easy to damage internal components or cause incomplete cleaning during cleaning, creating hygiene hazards.

[0004] Therefore, there is an urgent need to design a new type of pet feeder that ensures both ease of cleaning and avoids the impact of frequent disassembly on the stability of the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pet feeder.

[0006] The present invention provides a pet feeder, comprising a base and a cover detachably connected to the base. The base and the cover together form a food storage cavity. The side wall of the cover is provided with a food dispensing channel communicating with the food storage cavity. A turntable is provided inside the food storage cavity. A drive motor is provided inside the base. The drive motor includes a drive shaft that extends out of the base, and a first magnetic attractor is provided at the top of the drive shaft. A second magnetic attractor is provided on the side of the turntable near the base. A connecting hole is provided at the center of the side of the turntable near the base, and the second magnetic attractor is provided in the connecting hole. When the drive shaft extends into the connecting hole, the first magnetic attractor and the second magnetic attractor are magnetically connected.

[0007] Preferably, the connecting hole is a blind hole.

[0010] Preferably, the turntable has an annular edge, the base has a circular groove, the turntable is placed in the circular groove, and the annular edge contacts the sidewall of the circular groove.

[0011] Preferably, the opening of the grain outlet channel is inclined downward relative to the horizontal plane.

[0012] Preferably, a baffle is slidably disposed in the grain discharge channel, and a strip groove extending along the sliding direction of the baffle is provided on the grain discharge channel, and a toggle part extending out of the strip groove is provided on the baffle.

[0013] Preferably, the cover is a transparent cover, and an opening is provided on the side of the cover away from the base, and a detachable movable cover is provided in the opening.

[0014] Preferably, the base includes a detachably connected upper base and a lower base, which together form a receiving space when closed, and the drive motor is disposed in the receiving space.

[0015] Preferably, the base is further provided with a control circuit electrically connected to the drive motor. The control circuit includes a wireless communication module. The pet feeder also includes a control button that is signal-connected to the wireless communication module. The base is also provided with a switch and a charging port that are electrically connected to the control circuit.

[0016] Compared with the prior art, the pet feeder provided by this utility model has the following beneficial effects: 1. The pet feeder provided in this embodiment of the utility model has a base and a cover that are detachably connected and enclose a food storage chamber for storing pet food. The side wall of the cover has a food dispensing channel communicating with the food storage chamber. A turntable is installed inside the food storage chamber. A drive motor is installed inside the base. The drive motor includes a drive shaft that extends out of the base, and a first magnetic attractor is located at the top of the drive shaft. A connecting hole is located at the center of the turntable near the base, and a second magnetic attractor is located inside the connecting hole. When the drive shaft is inserted into the connecting hole, the first and second magnetic attractors are magnetically connected. When the motor starts, the drive shaft engages with the connecting hole, driving the turntable to rotate synchronously, thus transmitting power. Simultaneously, the first and second magnetic attractors keep the drive shaft tightly attached to the connecting hole, preventing axial disengagement due to vibration or other factors during rotation. When the turntable rotates, centrifugal force acts on the food on the turntable, causing the food to move towards the edge of the turntable and eventually flow out through the food dispensing channel. The rotation speed or angle of the turntable can be adjusted by the drive motor to achieve quantitative food dispensing. The drive shaft can be pulled out by overcoming the magnetic attraction, which allows for quick separation of the turntable and the base. This facilitates separate cleaning of the turntable and the inside of the grain storage chamber, preventing food residue from accumulating and breeding bacteria. It also avoids the risk of food debris and moisture corroding electrical components such as the drive motor.

[0017] 2. The pet feeder provided in this embodiment of the utility model has a blind hole for the connection hole. This design can further ensure the sealing of the food storage chamber and prevent food scraps from entering the connection hole from the turntable, causing jamming and unsanitary corners.

[0018] 3. The pet feeder provided in this embodiment of the utility model has a protruding part extending from the inner surface of the turntable on the side facing the cover. The protruding part is elongated. The protruding part provides a stable point of force for the user, facilitating quick and easy disassembly and installation of the turntable. The protruding part also prevents food from piling up or clogging. When the turntable rotates, the elongated protruding part guides the flow of food, allowing it to enter the food dispensing channel evenly and be dispensed more smoothly. The protruding part can also divide the food storage chamber into different spaces for storing different types of food.

[0019] 4. The pet feeder provided in this embodiment of the utility model has a third magnetic component on the side of the turntable near the base. A Hall switch is installed inside the base, and a detection hole is opened on the side of the base near the turntable corresponding to the third magnetic component. The sensing end of the Hall switch extends into the detection hole. The Hall switch cooperates with the third magnetic component to sense the positional relationship between the turntable and the base. This design ensures that the third magnetic component will be aligned with the sensing end of the Hall switch in the detection hole after the food tray is installed in place. Only after the Hall switch outputs a confirmation signal will the drive motor be allowed to start. This completely avoids the drive motor running idle or driving misaligned parts when the food tray is not installed or is installed crookedly, preventing equipment damage or food leakage.

[0020] 5. The pet feeder provided in this embodiment of the utility model has a turntable with an annular edge and a base with a circular groove. The turntable is placed in the circular groove, and the annular edge contacts the side wall of the circular groove. This design facilitates installation and provides circumferential restraint to the turntable, preventing lateral displacement, swaying, or tilting during rotation due to food pushing force, motor vibration, or pet contact. This ensures that the turntable rotates stably around the central axis, guaranteeing uniform food dispensing and reliable power transmission. Furthermore, the annular edge forms a physical barrier at the bottom of the food storage chamber, effectively preventing small food particles from leaking into the base through the gap between the turntable and the base, reducing the risk of contamination and damage to electrical components.

[0021] 6. In the pet feeder provided in this embodiment of the present invention, the opening of the food dispensing channel is inclined downward relative to the horizontal plane. The inclined opening can form a clear food dispensing trajectory, reducing food scattering or splashing and keeping the feeding environment clean.

[0022] 7. The pet feeder provided in this embodiment of the present invention has a baffle slidably installed in the food dispensing channel. The baffle is used to block or open the food dispensing path of the food dispensing channel. A strip groove extending along the sliding direction of the baffle is provided on the food dispensing channel. A toggle part extending out of the strip groove is provided on the baffle. The user can drive the baffle to move synchronously by sliding the toggle part along the strip groove to switch the on / off state of the food dispensing channel.

[0023] 8. The pet feeder provided in this embodiment of the utility model has a transparent cover with an opening on the side of the cover away from the base. A detachable movable cover is provided inside the opening. This design makes it convenient for users to observe the state inside the food storage chamber and clean or add food in a timely manner.

[0024] 9. The pet feeder provided in this embodiment of the utility model includes a base comprising a detachably connected upper base and a lower base. When the upper and lower bases are closed, they form an accommodating space, and a drive motor is disposed within the accommodating space. The upper and lower bases are detachable, facilitating the installation and maintenance of components within the accommodating space.

[0025] 10. The pet feeder provided in this embodiment of the utility model includes a control circuit electrically connected to the drive motor inside the base, and a switch and charging port electrically connected to the control circuit on the base. The operation of the drive motor can be controlled by preset programs in the control circuit, such as rotation duration, frequency, and start / stop timing, to achieve functions such as quantitative food dispensing and timed feeding. The external switch is directly connected to the control circuit, allowing for quick start / stop or mode switching of the feeder. The charging port eliminates the need for a dedicated power supply, improving ease of use. The control circuit includes a wireless communication module, and the pet feeder also includes a control button connected to the wireless communication module. This design allows the control button to be set independently and flexibly installed in a location easily accessible to the pet, enabling the pet to actively trigger food dispensing and enriching the pet's daily activities.

[0039] Please see Figures 1 to 4 The first embodiment of this utility model provides a pet feeder 1, including a base 10 and a cover 20 detachably connected to the base 10. The base 10 and the cover 20 enclose a food storage cavity 100. The side wall of the cover 20 is provided with a food dispensing channel 200 communicating with the food storage cavity 100. A turntable 30 is provided inside the food storage cavity 100. A drive motor is provided inside the base 10. The drive motor 101 includes a drive shaft 102. The drive shaft 102 extends out of the base 10, and a first magnetic suction member 103 is provided on the top of the drive shaft 102. A connecting hole 301 is provided on the side of the turntable 30 near the base 10. A second magnetic suction member 300 is provided in the connecting hole 301. When the drive shaft 102 extends into the connecting hole 301, the first magnetic suction member 103 and the second magnetic suction member 300 are magnetically connected.

[0040] Understandably, the base 10 and the cover 20 are detachably connected to form a food storage cavity 100 for storing pet food, and a food dispensing channel 200 is provided on the side wall of the cover 20 for dispensing food. The turntable 30, which is located in the food storage cavity 100, serves as the core component for food dispensing. It is detachably connected to the base 10 via magnetic attraction and engages with the drive shaft 102 through the connecting hole 301, and is driven to rotate by the drive motor 101.

[0041] Specifically, the drive shaft 102 of the drive motor 101 extends out of the base 10. When it engages with the connecting hole 301, the first magnetic member 103 at its top magnetically connects with the second magnetic member 300 inside the connecting hole 301. When the motor starts, the drive shaft 102 engages with the connecting hole 301, driving the turntable 30 to rotate synchronously, thus transmitting power. At the same time, the first magnetic member 103 and the second magnetic member 300 keep the drive shaft 102 tightly attached to the connecting hole 301, preventing it from axially dislodging due to vibration or other factors during rotation. When the turntable 30 rotates, centrifugal force acts on the food on the turntable 30, causing the food to move towards the edge of the turntable 30 and finally flow out through the food outlet channel 200, completing the feeding process.

[0042] Optionally, both the first magnetic component 103 and the second magnetic component 300 may be magnetic; or only one of them may be magnetic, while the other is an iron component. It should be noted that, regardless of the configuration, the magnetic strength of the first magnetic component 103 and the second magnetic component 300 must meet the actual usage requirements to ensure sufficient magnetic force for a stable connection.

[0043] Understandably, to reliably drive the drive shaft 102 to rotate the turntable 30, when the drive shaft 102 is inserted into the connecting hole 301, at least one set of mutually abutting rigid force transmission surfaces are formed between the outer peripheral surface of the drive shaft 102 and the hole wall of the connecting hole 301, so as to convert the rotational force of the drive shaft 102 into the torque of the turntable 30. In this embodiment, the specific shape of the drive shaft 102 and the connecting hole 301 is not limited, and they can be mutually matching square shaft and square hole, spline shaft and spline hole, hexagonal shaft and hexagonal hole, etc.

[0044] Understandably, in this embodiment, the detachable connection method between the cover 20 and the base 10 is not limited. For example, the cover 20 and the base 10 may be provided with corresponding buckles and grooves, and the detachable connection between the two can be achieved through the cooperation of the buckles and grooves. The cover 20 and the base 10 may also be detachably connected by threads.

[0045] Understandably, by controlling the drive motor 101, the rotation speed or angle of the turntable 30 can be adjusted to achieve quantitative feed dispensing, avoid food accumulation or blockage, and improve feeding efficiency. The connection hole 301 should be located at the center of the turntable 30 to ensure its stability when driven to rotate.

[0046] Understandably, the detachable design of the cover 20 and base 10 facilitates cleaning of the interior of the grain storage chamber 100 by opening the cover 20. The turntable 30 is magnetically connected to the base 10 via the first magnetic 103 and the second magnetic 300, allowing for direct separation and removal by overcoming magnetic force. This facilitates separate cleaning of the turntable 30 and the interior of the grain storage chamber 100, preventing food residue from accumulating and breeding bacteria. Electrical components such as the drive motor 101 are housed within the base 10, forming a physical isolation between them and the grain storage chamber. This also avoids the risk of food debris and moisture corroding the drive motor 101 and other electrical components during use and cleaning.

[0047] Specifically, an opening 104 is provided on the side of the base 10 near the grain storage chamber 100, corresponding to the drive shaft 102. The drive shaft 102 extends out of the base 10 through the opening 104. The opening 104 is slightly larger than the diameter of the drive shaft 102. This provides sufficient room for the drive shaft 102 to ensure smooth rotation, while preventing the opening 104 from being too large, which could cause food in the grain storage chamber 100 to enter the base 10 through gaps or get stuck in the gap between the drive shaft 102 and the opening 104.

[0048] Furthermore, the connection hole 301 is a blind hole that does not penetrate the bottom of the turntable 30. This design can further ensure the sealing of the grain storage chamber 100 and prevent food debris from entering the connection hole 301 from the turntable 30, causing jamming and unsanitary corners.

[0049] Furthermore, the turntable 30 is provided with a protrusion 302 protruding from the inner surface on the side facing the cover 20, and the protrusion 302 is elongated.

[0050] Understandably, the protrusion 302 provides the user with a stable point of leverage, facilitating the quick and easy disassembly and installation of the turntable 30. The protrusion 302 can also be configured in different shapes to divide the grain storage chamber 100 into different spaces for storing different types of food.

[0051] Specifically, in this embodiment, the protrusion 302 is a long, protruding strip that passes through the center of the turntable 30 and is integrally formed with the turntable 30. This design can also prevent food from accumulating or clogging. When the turntable 30 rotates, the long, protruding part 302 can guide the flow of food so that the food can enter the food outlet channel 200 evenly and be dispensed more smoothly.

[0052] Furthermore, a third magnetic suction element 304 is provided on the side of the turntable 30 near the base 10, and a Hall switch 109 is provided inside the base 10. A detection hole 111 is opened on the side of the base 10 near the turntable 30 corresponding to the third magnetic suction element 304, and the sensing end 110 of the Hall switch 109 extends into the detection hole 111.

[0053] Understandably, the Hall switch 109 cooperates with the third magnetic component 304 to sense the positional relationship between the turntable 30 and the base 10. This design ensures that after the food tray is installed in place, the third magnetic component 304 will be aligned with the sensing end 110 of the Hall switch 109 in the detection hole 111, triggering the Hall switch 109 to output a confirmation signal before allowing the drive motor 101 to start. This completely prevents the drive motor 101 from running idle or driving misaligned components when the food tray is not installed or is installed incorrectly, preventing equipment damage or food leakage.

[0054] Optionally, the third magnetic element 304 can be configured as one or more. When multiple elements are configured, they should be evenly distributed along the same circumference centered on the center of the turntable 30 to ensure that when the turntable 30 rotates around its central axis to different installation angles, at least one third magnetic element 304 can be precisely aligned with the Hall element in the detection hole 111 to trigger magnetic field induction. This enables reliable position detection of the turntable 30 at different installation angles, ensuring that the food tray can be determined to be in place and the motor can be started regardless of how it is rotated during installation.

[0055] Furthermore, the turntable 30 is provided with an annular edge 303, the base 10 is provided with a circular groove 105, the turntable 30 is placed in the circular groove 105, and the annular edge 303 contacts the side wall of the circular groove 105.

[0056] Understandably, a circular groove 105 is provided on the base 10 for easy user installation. The annular edge 303 contacts the side wall of the circular groove 105, which can circumferentially limit the turntable 30, preventing the turntable 30 from shifting laterally, shaking, or tilting during rotation due to food pushing, motor vibration, or pet touching, ensuring that the turntable 30 always rotates stably around the central axis, guaranteeing uniform food dispensing and reliable power transmission. Furthermore, the annular edge 303 can form a physical barrier at the bottom of the food storage chamber 100, effectively preventing small food particles from leaking into the base 10 from the gap between the turntable 30 and the base 10, reducing the risk of contamination and damage to electrical components.

[0057] Furthermore, the opening 204 of the grain discharge channel 200 is inclined downward relative to the horizontal plane.

[0058] Understandably, the downward-sloping opening 204 creates a clear food dispensing trajectory, reducing food spillage or splashing and keeping the feeding environment clean.

[0059] Please refer to further information. Figure 5 A baffle 201 is slidably installed inside the grain discharge channel 200. A strip groove 202 extending along the sliding direction of the baffle 201 is provided on the grain discharge channel 200. A toggle part 203 extending out of the strip groove 202 is provided on the baffle 201.

[0060] Understandably, the baffle 201 is used to block or open the grain discharge path of the grain discharge channel 200. Due to the cooperation of the strip groove 202 and the actuating part 203, the user can drive the baffle 201 to move synchronously by sliding the actuating part 203 along the strip groove 202 to switch the on / off state of the grain discharge channel 200.

[0061] Specifically, in this embodiment, the baffle 201 is an arc-shaped plate that matches the curvature of the cover 20. A placement cavity 208 is also provided between the cover 20 and the grain outlet channel 200. The placement cavity 208 is connected to the grain outlet channel 200. When it is necessary to open the grain outlet channel 200, the actuating part 203 is pushed to slide the baffle 201 into the placement cavity 208. The baffle 201 adopts an arc-shaped design that matches the curvature of the cover 20. When sliding, it can fit tightly against the outer side of the cover 20, avoiding excessive frictional resistance or jamming caused by shape mismatch, and ensuring that the baffle 201 can move smoothly when the actuating part 203 is pushed. The placement cavity 208 serves as a storage space when the baffle 201 is open, which can prevent the baffle 201 from interfering with the grain outlet and ensure the smoothness of the grain outlet. The diameter of the portion of the actuating part 203 extending out of the strip groove 202 is larger than the diameter of the portion of the actuating part 203 located inside the strip groove 202, to prevent the actuating part 203 from falling off the strip groove 202.

[0062] Understandably, to ensure the baffle 201 is more securely installed within the grain outlet channel 200, a guide rail (not shown) can be provided on the inner wall of the cover 20 corresponding to the edge of the baffle 201. The baffle 201 is then mounted on the guide rail and can slide along it. Furthermore, a locking structure (not shown) can be provided at both ends of the guide rail. When the user pushes the actuating part 203 to slide the baffle 201, the locking structure ensures that the baffle 201 remains stable in its current position. By sliding the actuating part 203 along the strip groove 202, the user can move the baffle 201 synchronously to switch the on / off state of the grain outlet channel 200.

[0063] Furthermore, the cover 20 is a transparent cover 20, and an opening 204 is provided on the side of the cover 20 away from the base 10, and a detachable movable cover 205 is provided in the opening 204.

[0064] Understandably, the transparent cover 20 allows users to observe the state inside the food storage chamber 100, such as the amount of food remaining or whether the food has spoiled, so that food can be added or cleaned in a timely manner. The opening 204 and the movable cover 205 allow users to add food directly without having to open the entire cover 20.

[0065] Please refer to the following: Figure 2 and Figure 3 Furthermore, the base 10 includes an upper base 106 and a lower base 107 that are detachably connected. When the upper base 106 and the lower base 107 are closed, they form a receiving space 108. The drive motor 101 is disposed in the receiving space 108.

[0066] Understandably, the upper base 106 and the lower base 107 are detachable to facilitate the installation and maintenance of components within the housing space 108.

[0067] In this embodiment, the detachable connection method of the upper base 106 and the lower base 107 is not limited. For example, the upper base 106 and the lower base 107 can be detachably connected by a snap-fit ​​or by a thread.

[0068] Please combine further Figure 1 and Figure 6 The base 10 also contains a control circuit (not shown) that is electrically connected to the drive motor 101. The base 10 also contains a switch 206 and a charging port 207 that are electrically connected to the control circuit.

[0069] Understandably, the operation of the drive motor 101 can be controlled by preset programs in the control circuit, such as rotation duration, frequency, and start / stop timing, to achieve functions such as quantitative feed dispensing and timed feeding. The external switch 206 is directly connected to the control circuit, which can quickly realize the overall start / stop or mode switching of the feeder. The charging port 207 eliminates the need for users to equip themselves with a dedicated power supply, improving ease of use.

[0070] Furthermore, the control circuit includes a wireless communication module (not shown), and the pet feeder 1 also includes a control button 40 that is signal-connected to the wireless communication module.

[0071] Understandably, due to the wireless communication module, the control button 40 can be installed separately. Users can flexibly place the control button 40 in a location easily accessible to the pet, allowing the pet to actively trigger food dispensing, thus enriching the pet's daily activities. Users can also operate the control button 40 remotely, improving the convenience of feeding.

[0072] Compared with the prior art, the pet feeder provided by this utility model has the following beneficial effects: 1. The pet feeder provided in this embodiment of the utility model has a base and a cover that are detachably connected and enclose a food storage chamber for storing pet food. The side wall of the cover has a food dispensing channel communicating with the food storage chamber. A turntable is installed inside the food storage chamber. A drive motor is installed inside the base. The drive motor includes a drive shaft that extends out of the base, and a first magnetic attractor is located at the top of the drive shaft. A connecting hole is located at the center of the turntable near the base, and a second magnetic attractor is located inside the connecting hole. When the drive shaft is inserted into the connecting hole, the first and second magnetic attractors are magnetically connected. When the motor starts, the drive shaft engages with the connecting hole, driving the turntable to rotate synchronously, thus transmitting power. Simultaneously, the first and second magnetic attractors keep the drive shaft tightly attached to the connecting hole, preventing axial disengagement due to vibration or other factors during rotation. When the turntable rotates, centrifugal force acts on the food on the turntable, causing the food to move towards the edge of the turntable and eventually flow out through the food dispensing channel. The rotation speed or angle of the turntable can be adjusted by the drive motor to achieve quantitative food dispensing. The drive shaft can be pulled out by overcoming the magnetic attraction, which allows for quick separation of the turntable and the base. This facilitates separate cleaning of the turntable and the inside of the grain storage chamber, preventing food residue from accumulating and breeding bacteria. It also avoids the risk of food debris and moisture corroding electrical components such as the drive motor.

[0073] 2. The pet feeder provided in this embodiment of the utility model has a blind hole for the connection hole. This design can further ensure the sealing of the food storage chamber and prevent food scraps from entering the connection hole from the turntable, causing jamming and unsanitary corners.

[0074] 3. The pet feeder provided in this embodiment of the utility model has a protruding part extending from the inner surface of the turntable on the side facing the cover. The protruding part is elongated. The protruding part provides a stable point of force for the user, facilitating quick and easy disassembly and installation of the turntable. The protruding part also prevents food from piling up or clogging. When the turntable rotates, the elongated protruding part guides the flow of food, allowing it to enter the food dispensing channel evenly and be dispensed more smoothly. The protruding part can also divide the food storage chamber into different spaces for storing different types of food.

[0075] 4. The pet feeder provided in this embodiment of the utility model has a third magnetic component on the side of the turntable near the base. A Hall switch is installed inside the base, and a detection hole is opened on the side of the base near the turntable corresponding to the third magnetic component. The sensing end of the Hall switch extends into the detection hole. The Hall switch cooperates with the third magnetic component to sense the positional relationship between the turntable and the base. This design ensures that the third magnetic component will be aligned with the sensing end of the Hall switch in the detection hole after the food tray is installed in place. Only after the Hall switch outputs a confirmation signal will the drive motor be allowed to start. This completely avoids the drive motor running idle or driving misaligned parts when the food tray is not installed or is installed crookedly, preventing equipment damage or food leakage.

[0076] 5. The pet feeder provided in this embodiment of the utility model has a turntable with an annular edge and a base with a circular groove. The turntable is placed in the circular groove, and the annular edge contacts the side wall of the circular groove. This design facilitates installation and provides circumferential restraint to the turntable, preventing lateral displacement, swaying, or tilting during rotation due to food pushing force, motor vibration, or pet contact. This ensures that the turntable rotates stably around the central axis, guaranteeing uniform food dispensing and reliable power transmission. Furthermore, the annular edge forms a physical barrier at the bottom of the food storage chamber, effectively preventing small food particles from leaking into the base through the gap between the turntable and the base, reducing the risk of contamination and damage to electrical components.

[0077] 6. In the pet feeder provided in this embodiment of the present invention, the opening of the food dispensing channel is inclined downward relative to the horizontal plane. The inclined opening can form a clear food dispensing trajectory, reducing food scattering or splashing and keeping the feeding environment clean.

[0078] 7. The pet feeder provided in this embodiment of the present invention has a baffle slidably installed in the food dispensing channel. The baffle is used to block or open the food dispensing path of the food dispensing channel. A strip groove extending along the sliding direction of the baffle is provided on the food dispensing channel. A toggle part extending out of the strip groove is provided on the baffle. The user can drive the baffle to move synchronously by sliding the toggle part along the strip groove to switch the on / off state of the food dispensing channel.

[0079] 8. The pet feeder provided in this embodiment of the utility model has a transparent cover with an opening on the side of the cover away from the base. A detachable movable cover is provided inside the opening. This design makes it convenient for users to observe the state inside the food storage chamber and clean or add food in a timely manner.

[0080] 9. The pet feeder provided in this embodiment of the utility model includes a base comprising a detachably connected upper base and a lower base. When the upper and lower bases are closed, they form an accommodating space, and a drive motor is disposed within the accommodating space. The upper and lower bases are detachable, facilitating the installation and maintenance of components within the accommodating space.

[0081] 10. The pet feeder provided in this embodiment of the utility model includes a control circuit electrically connected to the drive motor inside the base, and a switch and charging port electrically connected to the control circuit on the base. The operation of the drive motor can be controlled by preset programs in the control circuit, such as rotation duration, frequency, and start / stop timing, to achieve functions such as quantitative food dispensing and timed feeding. The external switch is directly connected to the control circuit, allowing for quick start / stop or mode switching of the feeder. The charging port eliminates the need for a dedicated power supply, improving ease of use. The control circuit includes a wireless communication module, and the pet feeder also includes a control button connected to the wireless communication module. This design allows the control button to be set independently and flexibly installed in a location easily accessible to the pet, enabling the pet to actively trigger food dispensing and enriching the pet's daily activities.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
