Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pet products, and particularly relates to a pet feeding device with falling detection. BACKGROUND

[0002] With the improvement of people's living standards, more and more families choose to raise pets to add fun to life. However, the diet management of pets has become a big challenge for pet owners, and many owners will use a feeding machine to automatically feed the pets on a regular basis.

[0003] Most of the existing pet feeding machines focus on guaranteeing feeding. In order to ensure that the pets can eat smoothly, a large single grain output is generally designed, and a stacking type grain output mode is adopted. This mode cannot meet the individualized needs of a part of pet owners for less food and more meals. In addition, due to the different sizes and shapes of pet food and the mixing of large particles in small particle food, in order to be compatible with these larger or less flowable particles, the existing feeding machine usually needs to be designed with a larger cavity volume or a larger opening cross-sectional area. However, when the particles are small and have good flowability, the feeding machine is prone to drop a large amount of food at one time, thereby causing a "snow avalanche" of food, which not only causes waste of food, but also makes the grain outlet unable to be closed in time.

[0004] Therefore, the present application provides a pet feeding device with falling detection to solve the above problems. CONTENT OF THE UTILITY MODEL

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] This embodiment provides a pet feeding device with drop detection, such as... Figures 1-2 As shown, the pet feeding device includes a base 1 and a roller structure 2 mounted on the base 1 for dispensing food. The roller structure 2 includes a food bin 21 rotatably mounted on the base 1, a cover 22 screwed to the end of the food bin 21 away from the base 1, a food dispensing pipe 23 passing through the end of the cover 22 away from the food bin 21 and fixedly connected to the cover 22, internal threads 25 fixedly mounted in the cover 22 and the food dispensing pipe 23 for moving the pet food outward, and a motor 24 mounted on the base 1 for driving the food bin 21 to rotate. The food bin 21, the center of the food bin 21 and the food dispensing pipe 23 are coaxially arranged. The pet feeding device also includes a circuit board 3 fixedly mounted on the base 1 at a position below the outlet of the food dispensing pipe 23 away from the cover 22, and a light curtain connected to the input end of the circuit board 3 for detecting whether the pet food has fallen at the outlet of the food dispensing pipe 23. The motor 24 is connected to the output end of the circuit board 3.

[0030] In order to facilitate the installation and use of the motor 24, the base 1 is provided with a housing 11 at the position corresponding to the motor 24, and the motor 24 is fixedly installed in the housing 11. The design of the housing 11 provides a stable installation environment for the motor 24, which can effectively prevent the motor 24 from being interfered with by the external environment during operation, such as dust and moisture.

[0031] In use, when the motor 24 is started, it drives the grain bin 21 to rotate around its center, since the grain bin 21, the center of the grain bin 21 and the grain outlet pipe 23 are coaxially arranged, so the rotation of the grain bin 21 drives the cover 22 and the grain outlet pipe 23 to rotate together. However, in the process of rotation, the pet food is moved outward along the thread direction under the action of gravity and the friction of the internal thread 25. With the continuous rotation of the grain bin 21, the pet food is gradually pushed to the outlet of the grain outlet pipe 23 and discharged, so that it can be compatible with large-diameter or poor-flowing granular pet food. When the pet food falls from the outlet of the grain outlet pipe 23, it will block the light of the light curtain. After the light curtain detects the change, it will transmit a signal to the circuit board 3. After the circuit board 3 receives the signal, it will immediately control the motor 24 to stop rotating, so that the accurate control of the single-time food discharge amount can be ensured.

[0032] Specifically, the pet feeding device further comprises a detachable part 4 arranged on the grain bin 21 and the motor 24 for disassembling the grain bin 21 and the motor 24. The detachable part 4 comprises a special-shaped plug block 42 rotatably connected to the bin body 11 and fixedly connected with the output shaft of the motor 24, and a special-shaped plug hole 41 fixedly arranged at one end of the grain bin 21 away from the cover 22 for matching with the special-shaped plug block 42.

[0033] When it is necessary to disassemble the grain bin 21 for cleaning or maintenance, first, turn off the power of the motor 24 to ensure safety, then rotate or push the special-shaped plug block 42 to separate it from the special-shaped plug hole 41. Once the special-shaped plug block 42 is separated from the special-shaped plug hole 41, the grain bin 21 can be removed from the base 1 and the motor 24. Then, the cover 22 can be loosened to unseal the grain bin 21, so that the inside of the grain bin 21 can be cleaned and maintained. When it is necessary to install, align the grain bin 21 with the position on the base 1, and align the special-shaped plug hole 41 with the special-shaped plug block 42. Rotate or push the special-shaped plug block 42 to firmly insert it into the special-shaped plug hole 41, so as to ensure the stable connection between the grain bin 21 and the motor 24.

[0034] Further, the base 1 is provided with a support part 5 corresponding to the outlet of the grain outlet pipe 23 for supporting the grain outlet pipe 23. The support part 5 comprises a lower baffle 51 fixedly arranged on the base 1 corresponding to the outlet position of the grain outlet pipe 23 for supporting one side of the bottom end of the grain outlet pipe 23, and side baffles 52 fixedly arranged on the base 1 and located on both sides of the lower baffle 51 for supporting both sides of the grain outlet pipe 23. The end of the circuit board 3 away from the base 1 is fixedly connected with the lower baffle 51, and the light curtain is fixedly arranged at the intersection of the circuit board 3 and the lower baffle 51.

[0035] When the pet feeding device is working, the food dispensing pipe 23 will rotate along with the rotation of the food bin 21. At this time, the lower baffle 51 and the side baffle 52 provide stable support for the food dispensing pipe 23, preventing it from shaking or tilting due to rotation. At the same time, when it is necessary to disassemble the food bin 21, the food dispensing pipe 23 can be directly placed in the position of the support member 5 and rotated or lifted, so that it can directly contact the support member 5 to support and limit the food dispensing pipe 23, so as to further disassemble the food bin 21 and the cover 22.

[0036] Example 2

[0037] Unlike Example 1, as Figure 3 As shown, in order to further promote the even distribution and leveling of pet food, a vortex surface 221 is fixedly provided on the inner side of the cover 22 for lifting the pet food in the food bin 21 to the center. The design of the vortex surface 221 helps to lift the pet food to the center position when the food bin 21 rolls, further promoting the even distribution and leveling of pet food. In particular, when less than half of the pet food remains in the food bin 21, this design can ensure that the pet food can flow smoothly to the outlet, avoiding the problems of blockage or uneven food dispensing.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
