Description

Technical Field

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

[0002] Many families now keep pets (such as cats and dogs) and provide them with a comfortable living environment and nutritious food. With the development of technology, feeding pets is no longer limited to manual feeding. To reduce the workload of feeding or to avoid the inability to feed pets in time when the owner is away on business, many owners choose to feed their pets with smart feeding machines.

[0003] In existing technology, feeders typically consist of a food storage bin, a support shell, and a chassis stacked sequentially. A rotating unit is installed inside the food storage bin, and the bottom wall of the support shell is spaced apart from the chassis to form a receiving space. The rotating unit drives the food to rotate, and the food flows from the outlet of the food storage bin into the receiving slot of the support shell. The food then enters the receiving space through an opening in the bottom wall of the receiving slot. A feeding tray is connected to the front of the receiving space, and the food finally enters the feeding tray for the pet to eat, thus feeding the pet. When the weight of the food in the feeding tray reaches a preset value, the rotating unit stops rotating, ending the feeding process. However, although this type of feeder can automatically feed and stop, not all the food rotating from the food storage bin enters the feeding tray. Some food accumulates in the receiving space. This accumulated food may become damp or even spoil due to being detached from the food storage bin. When feeding resumes, this accumulated food enters the feeding tray along with fresh food, potentially causing illness in the pet. Utility Model Content

[0034] Example 1

[0035] This embodiment provides a pet feeder, such as Figures 1 to 3 As shown, this effectively prevents food from piling up in the feeding channel 12, avoids food from getting damp and rotting, and ensures the health of pets.

[0036] like Figures 1 to 3 As shown, the pet feeder includes a main housing 1, a food storage unit 2, a food dispensing assembly 3, and a food pushing assembly 4. The main housing 1 has a food outlet 11, a feeding channel 12, multiple food inlets, and multiple food outlet channels 14. Each food inlet corresponds to one of the multiple food outlet channels 14. The food inlets are connected to the feeding channel 12 via the food outlet channels 14, and the side of the feeding channel 12 opposite to the food outlet channels 14 is connected to the food outlet 11. The height of the feeding channel 12 is lower than the height of the food inlets, and the food outlet channels 14 extend vertically at an angle. The food storage unit 2 is mounted on the main housing 1. Multiple food storage units 2 are provided, each corresponding to one of the multiple food outlets 11. The inner cavity of the food storage unit 2 is connected to the food outlet channels 14 via the food outlets 11, and the food storage unit 2 is configured to store pet food. Multiple food dispensing assemblies 3 are provided, each corresponding to one of the multiple food storage units 2. The feed dispensing assembly 3 is located inside the main housing 1, and part of the feed dispensing assembly 3 extends into the inner cavity of the grain storage component 2, which is used to drive the food in the inner cavity of the grain storage component 2 into the feed inlet. The feed pushing assembly 4 is located at the end of the feeding channel 12 opposite to the feed outlet 11, and the feed pushing assembly 4 is used to push the food in the feeding channel 12 out of the feed outlet 11.

[0037] When it's time to feed the pet, the food in the food storage unit 2, driven by the food dispensing component 3, enters the feeding channel 12 through the food inlet and outlet channel 14. Then, the food pushing component 4 pushes the food out through the outlet 11, thus feeding the pet. By setting multiple food storage units 2, various types of food can be stored separately, preventing cross-contamination of flavors and allowing for simultaneous feeding of multiple types of food, helping the pet obtain more comprehensive nutrition. Once the food enters the feeding channel 12, the food pushing component 4 pushes the food within the channel, pushing all the food out through the outlet 11, effectively preventing food accumulation in the feeding channel 12, avoiding moisture and spoilage, and ensuring the pet's health.

[0038] In this embodiment, two grain storage units 2 are provided, with two grain inlets and two grain outlet channels 14 corresponding to them. In other embodiments, more than two grain storage units 2 may be provided, with more than two grain inlets and grain outlet channels 14 corresponding to them, depending on actual needs. This is not limited here.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the feed pushing assembly 4 includes a power supply component, a coil pipe 42, an electromagnetic coil 43, and a pushing component 44. The power supply component is disposed within the main housing 1. A limiting protrusion is provided circumferentially within the feeding channel 12. One end of the coil pipe 42 passes through the feeding channel 12 and abuts against the limiting protrusion. The other end of the coil pipe 42 extends out of the feeding channel 12 and abuts against the end of the feeding channel 12 opposite to the feed outlet 11. The outer diameter of the coil pipe 42 is smaller than the inner diameter of the feeding channel 12. The electromagnetic coil 43 is circumferentially wound around the outside of the coil pipe 42. The power supply component is energized and connected to the electromagnetic coil 43 to provide forward and reverse current to the electromagnetic coil 43. The pushing component 44 passes through the coil pipe 42 and is capable of reciprocating along the feeding channel 12 to push the food within the feeding channel 12.

[0040] When food enters the feeding channel 12, the power supply unit provides a positive current to the electromagnetic coil 43. The energized electromagnetic coil 43 generates a magnetic field, which acts on the pushing member 44, causing it to exert a positive force. This allows the pushing member 44 to move forward along the feeding channel 12, pushing the food out of the outlet 11 and feeding the pet. This prevents food from accumulating in the feeding channel 12 for extended periods, avoiding moisture and spoilage, and ensuring the pet receives fresh food, thus protecting its health. After feeding, the power supply unit provides a reverse current to the electromagnetic coil 43. This causes the pushing member 44 to exert a reverse force, allowing it to move backward along the feeding channel 12, pushing the food again. By controlling the direction of the current supplied by the power supply unit, the pushing member 44 can move back and forth along the feeding channel 12, thus feeding the pet.

[0041] Optionally, such as Figure 1 and Figure 2 As shown, the pushing member 44 includes a magnetically conductive part 441, a connecting part 442, a pushing part 443, and a stop part 444. The connecting part 442 passes through the coil pipe 42, and the magnetically conductive part 441 is disposed on the connecting part 442 and located inside the coil pipe 42. One end of the connecting part 442 is connected to the stop part 444, and the other end is connected to the pushing part 443, which is located inside the feeding channel 12. The pushing part 443 has a launching state that pushes food and an initial state that is away from the food outlet 11. In the launching state, the stop part 444 abuts against the coil pipe 42. In the initial state, the side of the pushing part 443 away from the food outlet 11 abuts against the limiting protrusion.

[0042] When food enters the feeding channel 12, the control power supply provides a positive current to the electromagnetic coil 43, causing the electromagnetic coil 43 to generate a magnetic field. Under the action of the magnetic field, the magnetic conductive part 441 generates a magnetic force, which causes the magnetic conductive part 441 to drive the connecting part 442, the pushing part 443, and the stop part 444 to move forward along the feeding channel 12 until the stop part 444 comes into contact with the coil pipe 42. During this process, the pushing part 443 pushes the food in the feeding channel 12 and pushes the food out of the food outlet 11, thereby preventing the food from accumulating in the feeding channel 12 and preventing the food from getting damp and rotting. After the magnetic conductive part 441 generates a magnetic force, it will propel forward instantly, causing the food to be ejected from the food outlet 11 in a shooting motion, increasing the interaction between the pet and attracting the pet to eat. After the food is pushed out, the control power supply unit provides a reverse current to the electromagnetic coil 43, which causes the magnetic part 441 to generate a reverse magnetic force. This causes the magnetic part 441 to drive the connecting part 442, the pushing part 443 and the stop part 444 to move backward along the feeding channel 12 until the pushing part 443 comes into contact with the limiting protrusion, so that the pushing part 443 can push out the food again.

[0043] Optionally, such as Figure 1 and Figure 3 As shown, the feed unloading assembly 3 includes a rotary drive mechanism 31 and a sorting structure 32. The housing of the rotary drive mechanism 31 is disposed within the main housing 1, and the output end of the rotary drive mechanism 31 is connected to the sorting structure 32 via a transmission connection. The sorting structure 32 is disposed within the inner cavity of the feed storage unit 2, and the sorting structure 32 is provided with a sorting channel 321. Food in the feed storage unit 2 can enter the sorting channel 321, which has a feed unloading state communicating with the feed inlet and a blocked state blocking the feed inlet.

[0044] When it is time to feed the pet, the rotary drive mechanism 31 is activated, which drives the sorting structure 32 to rotate, so that the food in the food storage unit 2 enters the sorting channel 321 of the sorting structure 32. If the sorting channel 321 is blocked at this time, the sorting structure 32 will continue to rotate with the food, so that the sorting structure 32 rotates until the sorting channel 321 is connected to the food inlet. Even if the sorting channel 321 is in the food feeding state, the food will enter the food outlet channel 14 from the food inlet through the sorting channel 321, and finally enter the feeding channel 12. Then, under the action of the food pushing component 4, the food in the feeding channel 12 is pushed out from the food outlet 11.

[0045] Optionally, such as Figure 1 and Figure 3 As shown, the sorting structure 32 includes a rotating shaft 322, a sorting disc 323, and spiral blades 324. The rotating shaft 322 is connected to the output end of the rotary drive mechanism 31, and passes vertically through the housing and into the inner cavity of the grain storage component 2. The spiral blades 324 are circumferentially wound around the rotating shaft 322 and extend vertically. The sorting disc 323 includes a connecting sleeve and multiple sorting blades. The connecting sleeve is fitted onto the rotating shaft 322 and is located below the spiral blades 324. The multiple sorting blades are circumferentially spaced on the connecting sleeve, and adjacent sorting blades form a sorting channel 321. The lower end of the spiral blades 324 communicates with any of the sorting channels 321.

[0046] When it is time to feed the pet, the rotary drive mechanism 31 is activated. The rotary drive mechanism 31 drives the rotating shaft 322, the sorting tray 323, and the spiral blades 324 to rotate synchronously. During this process, the spiral blades 324 rotate the food in the food storage unit 2 and the food is transferred from the lower end of the spiral blades 324 into the sorting channel 321. When the sorting tray 323 rotates to the point where the sorting channel 321 connects with the food inlet, the food enters the food outlet channel 14 from the sorting channel 321 through the food inlet, and finally enters the feeding channel 12. By setting the spiral blades 324 and the sorting tray 323, the amount of food entering the feeding channel 12 each time can be guaranteed to be the same, thereby more accurately controlling the amount of food consumed by the pet and avoiding overfeeding which may affect the pet's digestion.

[0047] For example, the rotary drive mechanism 31 includes a rotary motor, etc.

[0048] In this embodiment, five sorting blades are provided. In other embodiments, two to four, or even more than five sorting blades may be provided as needed; this is not limited here.

[0049] Optionally, the pet feeder also includes a weighing platform. The weighing platform is located on the bottom wall of the feeding channel 12 and is used to detect the weight of the food within the feeding channel 12. When feeding a pet, food enters the feeding channel 12 under the action of the food dispensing component 3. When the weighing platform detects that the weight of the food in the feeding channel 12 is the preset feeding weight, it stops the food dispensing component 3 from pushing the food into the food outlet 11. Then, the food pushing component 4 pushes the food out of the food outlet 11. By setting up a weighing platform, the amount of food fed to the pet can be more accurately controlled, precisely controlling the pet's food intake and contributing to scientific pet feeding.

[0050] For example, the weighing platform includes pressure sensors, etc.

[0051] Optionally, the pet feeder also includes a drying element, which is located on the inner wall of the food storage container 2. By installing the drying element, moisture inside the food storage container 2 can be absorbed, thereby reducing the humidity of the food, keeping the food dry, helping to prevent food spoilage and mold, and extending its shelf life.

[0052] For example, the drying component includes a bamboo charcoal bag. The bamboo charcoal bag is hung on the inner wall of the grain storage container 2, which not only keeps the food inside the container 2 dry but also prevents the formation of odors. In other embodiments, the drying component also includes a silicone bag, etc., which is not limited here.

[0053] Example 2

[0054] Based on the same inventive concept as Embodiment 1, this embodiment provides a pet feeder. The difference between this embodiment and Embodiment 1 is that the food pushing assembly 4 includes a push plate and a telescopic drive mechanism. The housing of the telescopic drive mechanism is disposed within the feeding channel 12 and located on the side of the feeding channel 12 away from the food outlet 11. The output end of the telescopic drive mechanism is connected to the push plate via a transmission connection. The telescopic drive mechanism is used to drive the push plate to move along the feeding channel 12 to push the food within the feeding channel 12. When food enters the feeding channel 12, the telescopic drive mechanism is extended, driving the push plate forward, thus pushing the food forward and ejecting all the food from the food outlet 11 out of the feeding channel 12. This prevents food from accumulating in the feeding channel 12 for extended periods, avoids food spoilage due to moisture, ensures the pet can eat fresh food, and safeguards the pet's health. After the food is ejected, the telescopic drive mechanism is retracted, driving the push plate backward to its initial position, facilitating the telescopic drive mechanism to push the food again.

[0055] For example, the telescopic drive mechanism includes a telescopic cylinder or a telescopic electric cylinder, etc.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
