[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0044] like Figure 1-8 As shown in the figure, this embodiment discloses a pet feeder, including a main body 1. A feeding tray 4 is rotatably disposed inside the main body 1, and multiple feeding slots 4a are arranged in a ring around its center of rotation. The outer edge of the feeding tray 4 cooperates with the inner wall of the main body 1 to form a support, allowing the feeding tray 4 to rotate smoothly within the main body 1 around its central axis. Each feeding slot 4a is used to hold pet food, which can be dry food, wet food, or treats. Different feeding slots 4a are separated from each other to prevent cross-contamination or mixing of different types of food.

[0045] Furthermore, combined Figure 1 As shown, the upper cover 2 is pivotally connected to the main body 1. The upper cover 2 is connected to the main body 1 via a hinge structure and can be opened and closed around the connecting axis. A switch 5 is provided on the front edge of the main body 1. The latch of the switch 5 hooks onto the upper cover 2 to keep the upper cover 2 closed. Pressing the switch 5 unlocks it, allowing the upper cover to separate from the main body 1 so that food can be added to the feeding dish 4. When the upper cover 2 is closed on the main body 1, a closed food storage space is formed between the upper cover 2 and the feeding dish 4. This space can effectively isolate the external environment when the feeding opening 2a is not opened, preventing dust, foreign objects and insects from entering, and maintaining the hygiene of the food storage space and the freshness of the food.

[0046] Furthermore, sensors are mounted on the main body 1 and / or the upper cover 2 to detect whether a pet is approaching. In this embodiment, the sensors can be of the type of distance sensor 7 and RFID sensor, wherein the distance sensor 7 includes types such as infrared sensor, ultrasonic sensor, and laser sensor. In this embodiment, the distance sensor 7 specifically adopts an ultrasonic sensor. The sensor is connected to the control circuit on the circuit board 11 and can transmit the detected pet approach signal to the control system to trigger the corresponding feeding action.

[0047] Furthermore, combined Figure 2 As shown, a feeding port 2a is located on the upper cover 2. The opening size of the feeding port 2a matches the size of a single feeding trough 4a, ensuring that the pet can easily access the food when the feeding trough 4a is aligned with the feeding port 2a. A door 3 is located above the feeding port 2a and is connected to the upper cover 2 via hinges, allowing the feeding port 2a to be opened or closed. During non-feeding periods, the door 3 remains closed to prevent the pet from accessing the food and to prevent external contamination. During feeding periods, when a sensor detects a pet approaching, the door 3 automatically opens, exposing the corresponding feeding trough 4a, allowing the pet to eat directly.

[0048] Furthermore, combined Figure 3 As shown, a first motor 8 is installed inside the upper cover 2. The first motor 8 is connected to the door 3 and is used to drive the door 3 to open or close. The first motor 8 can be a geared DC motor or a stepper motor, which, together with gears, connecting rods, or slide rail mechanisms, achieves smooth opening and closing of the door 3, with high control precision and low operating noise, thereby achieving automated feeding control without disturbing the pet. In this embodiment, the motor shaft of the first motor 8 directly drives the door 3 to open and close.

[0049] Furthermore, combined Figure 4-6 As shown, the main body 1 contains a second motor 9, which is connected to the center of the feeding tray 4 and drives the feeding tray 4 to rotate, so that multiple feeding troughs 4a are aligned with the feeding opening 2a in sequence. The second motor 9 is fixedly mounted on a bracket in the installation space, and its output shaft has a spline-shaped connecting part 9a. Correspondingly, a spline-shaped connecting groove 4b is opened at the center of the bottom of the feeding tray 4. The connecting groove 4b and the connecting part 9a are interlocked and cooperate with each other, and the torque is transmitted through the spline, so as to realize the stable drive of the second motor 9 on the feeding tray 4 and prevent slippage or displacement during long-term use.

[0050] Furthermore, combining Figure 7As shown, the main body 1 is equipped with an angle sensor 12, which is used to detect the rotation angle of the feeding tray 4. The angle sensor 12 can be a Hall sensor, photoelectric encoder or potentiometer, etc. By monitoring the angle position of the feeding tray 4 in real time, the detection signal is fed back to the control system to ensure that the feeding trough 4a and the feeding port 2a are accurately aligned, and to avoid deviations that would prevent the food from being accurately fed.

[0051] Furthermore, combined Figure 2 As shown, the surface of the top cover 2 has a groove 2b, and the feeding opening 2a is located at the bottom of the groove 2b. When the pet is eating, its head can be accurately inserted into the feeding opening 2a, effectively reducing the possibility of food splashing or falling out.

[0052] Furthermore, the sensor includes a distance sensor 7, which is installed near the feeding port 2a to detect the approach distance of the pet; and / or the sensor includes an RFID sensor for use in conjunction with an RFID tag worn on the pet to identify different individual pets and enable targeted feeding.

[0053] Furthermore, combined Figure 8 As shown, the semiconductor cooler 10 is installed in the cooling mounting position inside the main body 1. Its working surface is in close contact with the feeding tray 4, and it transfers low temperature to the food storage area inside the feeding tray 4 through heat conduction to achieve food cooling and preservation. On the other side of the semiconductor cooler 10, heat dissipation fins 10a are provided, which are in close contact with its heating surface to absorb the heat generated during operation. A cooling fan 10b is arranged on one side of the heat dissipation fins 10a, with the air inlet of the cooling fan 10b facing the heat dissipation fins 10a. Through forced convection, heat is carried into the heat dissipation channel 1a and exhausted to the outside air of the main body 1 through the heat dissipation grilles 1b at both ends, forming a highly efficient heat exchange channel to ensure the continuous and stable operation of the cooling system.

[0054] Furthermore, combining Figure 5 As shown, the main body 1 has a horizontally extending heat dissipation channel 1a. At both ends of the heat dissipation channel 1a are heat dissipation grilles 1b for air circulation. The heat dissipation channel 1a penetrates the outer shell of the main body 1 and is separated from the internal installation space, thus ensuring heat dissipation efficiency while preventing external dust and hair from entering the internal working cavity. The installation space is used to accommodate components such as the second motor 9, the semiconductor cooler 10, the angle sensor 12, and the circuit board 11. A heat dissipation hole 1c is provided at the bottom of the installation space to dissipate the heat generated by the second motor 9, the circuit board 11, and other components into the external air.

[0055] Furthermore, the upper cover 2 is equipped with a disinfection device (not shown in the figure), which includes an ozone generator and / or an ultraviolet lamp for sterilizing the feeding port 2a and its surrounding area. The disinfection device can automatically operate after each feeding or at set time intervals, effectively inhibiting bacterial growth and improving the hygiene level of the feeder.

[0056] Furthermore, combined Figure 2 As shown, the surface of the main body 1 is provided with a display panel 6, which is used to display information such as feeding time and equipment working status, so that users can understand the operation of the equipment in real time.

[0057] Furthermore, combining Figure 1-2 As shown, in different usage scenarios, the multiple feeding troughs 4a of the feeding tray 4 can be divided into different functional zones.

[0058] In the first usage scenario, the feeding tray 4 has six equally distributed feeding troughs 4a, each of which can correspond to food for different days or different meals, realizing timed and quantitative feeding. For example, the six feeding troughs 4a correspond to pet food for six days from Monday to Saturday, and the control board controls the second motor 9 to advance one feeding trough 4a each day.

[0059] In the second usage scenario, the six feeding troughs 4a each hold different types of food, allowing for food combinations to meet the pet's diverse nutritional needs during feeding. For example, the pet can be fed multiple times a day, with different types of food each time.

[0060] In the third usage scenario, there are multiple pets in the home, each wearing a unique RFID tag. When the sensor detects a specific pet approaching, the system controls the feeding tray 4 to rotate to the corresponding feeding trough 4a. For example, one feeding trough 4a contains cat food for cats, and another feeding trough 4a contains dog food for dogs, thus allowing multiple pets to share the same feeder without interfering with each other.
