[0034] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0035] Figure 1 The utility model discloses an embodiment structure of the pet feeder for realizing accurate feeding Figure 1 . Please see Figure 1 、 Figure 2 and Figure 3 , the pet feeder for realizing accurate feeding includes: storage bin 1, signal receiver 2 (see Figure 3 ), controller 3 (see Figure 3 ), material distributing assembly 4 and feeding assembly 5.

[0036] Among them, storage bin 1 is used to store pet feed. Exemplarily, the storage bin 1 adopts a cylindrical structure, which is hollow inside to store pet feed, and the top of the storage bin 1 is open and provided with a cover, which facilitates the addition of pet feed to the storage bin 1.

[0037] Signal receiver 2 is used to receive the induction signal emitted by the signal transmitter 6 provided on the pet. It should be noted that in the embodiment, one signal receiver 2 and multiple signal transmitters 6 are provided, each signal transmitter 6 emits an induction signal of different frequency and is provided on a different pet, and when the pet approaches the pet feeder, the signal receiver 2 can receive the induction signal emitted by the signal transmitter 6 on the pet.

[0038] Controller 3 is electrically connected with the signal receiver 2, used to receive and identify the induction signal, and then generate a corresponding quantitative feeding signal according to the feeding plan corresponding to the induction signal. It should be noted that the feeding plan of each pet is pre-stored in the controller 3, and the feeding plan of each pet contains the corresponding feeding amount of the pet, and the controller 3 can identify the feeding plan corresponding to the induction signal after receiving the induction signal, and then generate a corresponding quantitative feeding signal according to the feeding plan.

[0039] Material distributing assembly 4 is electrically connected with the controller 3, and the inlet 4A (see Figure 4 ) of the material distributing assembly 4 is provided at the bottom of the storage bin 1 and communicates with the storage bin 1, and the material distributing assembly 4 is used to receive the quantitative feeding signal and separate the pet feed sliding into the inlet 4A according to the quantitative feeding signal, and then the pet feed is discharged from the outlet 4B (see Figure 5) and discharged. The dispensing assembly 4 separates the pet food that slides in from the feeding port 4A, and discharges the separated pet food from the discharge port 4B of the dispensing assembly 4. The dispensing assembly 4 can separate the pet food in the storage bin 1, so that the amount of pet food discharged from the dispensing assembly 4 each time is maintained within a certain range. By controlling the number of times the dispensing assembly 4 discharges pet food, the total amount of pet food added to the feeding assembly 5 during each feeding process can be controlled, thereby achieving the purpose of quantitative feeding. In this embodiment, after receiving the quantitative feeding signal sent by the controller 3, the dispensing assembly 4 confirms how much pet food needs to be separated and discharged into the feeding assembly 5 according to the quantitative feeding signal for the pet to eat.

[0040] The feeding assembly 5 is arranged adjacent to the discharge port 4B, so that the pet food discharged from the discharge port 4B falls into the feeding assembly 5. For example, the feeding assembly 5 is arranged below the discharge port 4B, and after the pet food in the dispensing assembly 4 is separated quantitatively, it slides under the action of gravity from the discharge port 4B to the feeding assembly 5.

[0041] Specifically, initially, when the pet does not approach the pet feeder, the pet feeder is not activated and feeding is not performed. When the pet approaches the pet feeder, the signal receiver 2 begins to receive the sensing signal emitted by the signal emitter 6 on the pet and sends the sensing signal to the controller 3. The controller 3 identifies the sensing signal and confirms the feeding plan corresponding to the sensing signal, generates a quantitative feeding signal according to the feeding amount of the pet in the feeding plan, and sends the quantitative feeding signal to the dispensing assembly 4. The dispensing assembly 4 separates the pet food according to the feeding amount in the quantitative feeding signal after receiving the quantitative feeding signal, and discharges the separated pet food to the feeding assembly 5 for the pet to eat. Each pet can correspond to a signal emitter 6, and each signal emitter 6 emits a signal of different frequency, so that each pet corresponds to a sensing signal, and the controller 3 can achieve quantitative feeding for each pet according to the different sensing signals, thereby meeting the needs of multi-pet families.

[0042] The pet feeder of the present embodiment can achieve precise feeding. By arranging the signal receiver 2 and the signal emitter 6 that emits sensing signals of different frequencies on different pets, the corresponding pet can be identified according to the sensing signal emitted by the signal emitter 6, and the dispensing assembly 4 can be controlled to quantitatively feed the pet according to the pre-set feeding plan for the pet. The feeding plans for different pets are different, so that the pet feeder of the present embodiment can quantitatively feed different pets, avoiding overfeeding or underfeeding, and meeting the feeding needs of multi-pet families without the need to purchase multiple pet feeders.

[0043] Further, in order to avoid pets fighting for food, on the basis of the above embodiments, in other embodiments, for example,Figure 2 As shown, the pet feeder further comprises a housing 7, the storage bin 1, the dispensing assembly 4, the feeding assembly 5 and the controller 3 are arranged in the housing 7, the housing 7 is provided with a feeding window 71, the signal receiver 2 and the feeding assembly 5 are arranged in the housing 7 and adjacent to the feeding window 71.

[0044] Specifically, by arranging the feeding window 71 on the housing 7 and arranging the feeding assembly 5 in the housing, when the pet feeds, the pet needs to put the head into the feeding window 71, and the size of the feeding window 71 is limited, only one pet can put the head into the feeding window 71, so that the pet will not be robbed when feeding, and the pet's own feeding is ensured.

[0045] Further, the housing 7 is further provided with a display screen and a touch screen for displaying relevant information and interacting.

[0046] Further, in the embodiment, the signal receiver 2 comprises an RFID induction coil, the signal transmitter 6 comprises an RFID electronic tag, the RFID induction coil is arranged adjacent to the feeding window 71, and the RFID electronic tag is arranged at the neck of the pet.

[0047] Specifically, RFID is the abbreviation of Radio Frequency Identification, also known as electronic tag, RFID is an automatic identification technology, RFID is a technology that uses radio frequency signals to realize non-contact information transmission through space coupling (alternating magnetic field or electromagnetic field) and achieves identification through the transmitted information. In the embodiment, the RFID electronic tag is used as the signal transmitter 6, and the signal transmitter 6 is installed in the neck area of the pet; the RFID induction coil is used as the signal receiver 2 for receiving the radio frequency signals sent by the RFID electronic tag. It should be noted that the power of the signal transmitter 6 and the signal receiver 2 needs to be set in the embodiment to limit the range of the signal receiver 2 that can receive the induction signals, and the signal receiver 2 cannot receive signals beyond the range, so that the signal receiver 2 can receive the signals transmitted by the signal transmitter 6 when the signal transmitter 6 is close to the preset range of the signal receiver 2, preventing false touch. Preferably, the signal receiver 2 should be arranged adjacent to the feeding assembly 5, when the pet needs to feed, the neck area of the pet will be close to the feeding assembly 5, arranging the signal receiver 2 adjacent to the feeding assembly 5 and arranging the signal transmitter 6 in the neck area of the pet, so as to facilitate receiving the signals transmitted by the signal transmitter 6 when the pet is close to the feeding assembly 5.

[0048] Further, in order to ensure the cleanliness of the feeding assembly 5 and avoid the contamination of the feeding assembly 5 affecting the health of the pet, on the basis of the above embodiment, in other embodiments, such as Figure 6 andFigure 7 As shown, the feeding assembly 5 comprises a mounting base 51, a feeding bowl 52, a first driving motor 53 and a first transmission assembly 54. One end of the feeding bowl 52 is rotatably connected to the mounting base 51. The output end of the first driving motor 53 is connected to the first transmission assembly 54. The first transmission assembly 54 is connected to one end of the feeding bowl 52. The first driving motor 53 drives the first transmission assembly 54 to rotate, and the first transmission assembly 54 drives the feeding bowl 52 to rotate, so that the feeding bowl 52 rotates between a first preset position where the pet cannot eat and a second preset position where the pet can eat.

[0049] Specifically, the rotatable connection between the feeding bowl 52 and the mounting base 51 can be achieved by a rotating shaft 42. A mounting hole is provided on the mounting base 51, and the rotating shaft 42 is rotatably arranged in the mounting hole. The rotating shaft 42 is connected to the feeding bowl 52. Thus, the rotatable connection between the feeding bowl 52 and the mounting base 51 is achieved. It should be noted that the feeding bowl 52 needs to rotate between the first preset position and the second preset position. When the rotatable feeding bowl 52 is installed on the pet feeder, a corresponding space needs to be reserved on the pet feeder for the rotation of the pet feeder. In order to better maintain the cleanliness of the feeding bowl 52, when the feeding bowl 52 is rotated to the first preset position, the bowl opening can be attached to the shell area of the pet feeder to prevent foreign matter from falling into the feeding bowl 52. Therefore, the first preset position should also be set in combination with the shell structure of the pet feeder. In this embodiment, the first preset position and the second preset position are pre-set. For example, as shown in Figure 7 As shown, the first preset position can be a high position, that is, by rotating the feeding bowl 52, one end of the feeding bowl 52 is obviously raised, so that the pet cannot touch the bowl cavity area of the feeding bowl 52. When the rotatable feeding bowl 52 device is installed on the pet feeder, the feeding bowl 52 can be rotated to one end to be raised, so that the bowl opening area of the feeding bowl 52 is close to the side wall or other area of the pet feeder, so that the pet cannot touch the bowl cavity area of the feeding bowl 52. As shown in Figure 6 As shown, the second preset position is an area convenient for the pet to eat, for example, the position of placing the feeding bowl 52 on the ground so that the pet can eat by lowering its head.

[0050] In addition, in order to reduce the manual operation of the user, the first driving motor 53 and the first transmission assembly 54 are arranged, the output end of the first driving motor 53 is connected with the first transmission assembly 54, the first transmission assembly 54 is connected with one end of the feeding basin 52, the first driving motor 53 drives the first transmission assembly 54 to rotate, the first transmission assembly 54 drives the feeding basin 52 to rotate, so that the feeding basin 52 rotates between the first preset position where the pet cannot eat and the second preset position where the pet can eat, thereby the user does not need to manually rotate the feeding basin 52. The first driving motor 53 can be controlled by a switch, when the user turns on the switch, the first driving motor 53 starts to work and drives the feeding basin 52 to rotate, when the user turns off the switch, the first driving motor 53 stops working.

[0051] In the embodiment, the feeding basin 52 is arranged to rotate on the mounting seat 51, when the pet needs to eat, the feeding basin 52 is rotated to the second preset position to allow the pet to eat, when the pet finishes eating, the feeding basin 52 is rotated to the first preset position where the pet cannot eat, which is only put down when the pet eats and is collected when the pet does not eat, which is beneficial to keep the feeding basin 52 clean and prevent the pet from polluting the feeding basin 52 during the non-eating time, thereby ensuring the cleanliness of the pet feeding environment and avoiding affecting the health of the pet.

[0052] Further, in order to further improve the intelligent degree and prevent the feeding basin 52 from being excessively rotated, on the basis of the above embodiment, in other embodiments, as shown in Figure 8 The feeding assembly 5 further comprises a first limiting piece 55, a first trigger piece 56, a second limiting piece 57 and a second trigger piece 58, the first limiting piece 55 and the second limiting piece 57 are arranged on the mounting seat 51 and are respectively electrically connected with the first driving motor 53, the first trigger piece 56 and the second trigger piece 58 are arranged on the first transmission assembly 54, the first transmission assembly 54 drives the first trigger piece 56 and the second trigger piece 58 to rotate when rotating; the first limiting piece 55 is provided with a first elastic switch 551, the first elastic switch 551 is arranged on the rotation path of the first trigger piece 56, when the feeding basin 52 rotates to the first preset position, the first trigger piece 56 just presses the first elastic switch 551, the first limiting piece 55 is triggered and controls the first driving motor 53 to stop working; the second limiting piece 57 is provided with a second elastic switch 571, the second elastic switch 571 is arranged on the rotation path of the second trigger piece 58, when the feeding basin 52 rotates to the second preset position, the second trigger piece 58 just presses the second elastic switch 571, the second limiting piece 57 is triggered and controls the first driving motor 53 to stop working.

[0053] It should be noted that in the embodiment, the first trigger 56 is provided with the first protrusion 561, the second trigger 58 is provided with the second protrusion 581, the first elastic switch 551 is arranged on the rotating path of the first protrusion 561, the second elastic switch 571 is arranged on the rotating path of the second protrusion 581, when the feeding bowl 52 rotates to the first preset position, the first protrusion 561 just presses the first elastic switch 551, the first limiting part 55 is triggered, when the feeding bowl 52 rotates to the second preset position, the second protrusion 581 just presses the second elastic switch 571, the second limiting part 57 is triggered.

[0054] Specifically, when the elastic switch is pressed, it will deform, so that the internal circuit is connected, and after stopping pressing, the elastic switch restores to the original state due to its own elasticity, and its internal circuit will be disconnected. In the embodiment, when the first driving motor 53 starts to work, the first protrusion 561 or the second protrusion 581 starts to rotate, during the rotation, when the first protrusion 561 touches the first elastic switch 551, the first elastic switch 551 is pressed, the first elastic switch 551 is connected, the first limiting part 55 is triggered by sensing the electric signal, and the first driving motor 53 is controlled to stop working, and when the first protrusion 561 does not touch the first elastic switch 551, the first elastic switch 551 is always in a disconnected state, and the first limiting part 55 will not be triggered; when the second protrusion 581 touches the second elastic switch 571, the second elastic switch 571 is pressed, the second elastic switch 571 is connected, the second limiting part 57 is triggered by sensing the electric signal, and the first driving motor 53 is controlled to stop working, and when the second protrusion 581 does not touch the second elastic switch 571, the second elastic switch 571 is always in a disconnected state, and the second limiting part 57 will not be triggered.

[0055] Further, in order to improve the intelligent degree, on the basis of the above embodiment, in other embodiments, as shown in Figure 3 The first driving motor 53 is electrically connected with the controller 3, and the controller 3 is further used for controlling the first driving motor 53 to work to drive the feeding bowl 52 to rotate from the first preset position to the second preset position after receiving the sensing signal; or the controller 3 is further used for controlling the first driving motor 53 to work to drive the feeding bowl 52 to rotate from the second preset position to the first preset position after not receiving the sensing signal.

[0056] Specifically, in the initial state, the feeding bowl 52 is in a first preset position where the pet cannot eat. After the pet approaches the feeding bowl 52, when the signal receiver 2 receives the induction signal emitted by the signal emitter 6, the controller 3 controls the first driving motor 53 to work, the first driving motor 53 drives the first transmission assembly 54, and the first transmission assembly 54 drives the feeding bowl 52 to rotate from the first preset position to a second preset position where the pet can eat. When the pet finishes eating and moves away from the feeding bowl 52, the signal receiver 2 cannot receive the induction signal, the controller 3 controls the first driving motor 53 to drive the first transmission assembly 54, and the first transmission assembly 54 drives the feeding bowl 52 to rotate from the second preset position to the first preset position.

[0057] The present embodiment automatically controls the opening and closing of the feeding bowl 52 according to whether the pet approaches the feeding bowl 52 through the controller 3, the signal emitter 6 and the signal receiver 2, so that the rotatable feeding bowl 52 device has a higher degree of automation and intelligence, further reduces the manual operation that the user needs to perform, and improves the user experience.
