[0043] See also Figures 1 to 9The present embodiment provides a pet feeder that can seal and store pet food to avoid the risk of spoilage of pet food. The pet feeder includes a food storage barrel 1, a food discharging mechanism 2, and a vacuum assembly 3. The food storage barrel 1 can be connected to the atmosphere, a first food discharging port 131 is provided at the bottom of the food storage barrel 1, and a food distributing assembly 6 is rotatably provided in the food storage barrel 1. The grain discharging mechanism 2 is arranged below the grain storage barrel 1. The grain discharging mechanism 2 includes a bearing platform 21 and a grain discharging assembly.

The grain discharging assembly can be rotated and switched between a first position and a second position. When in the first position, the blocking member 23 is opposite to the first grain discharging port 131. When in the second position, the grain discharging channel 22 is opposite to the first grain discharging port 131. Driving the bearing platform 21 to rise and fall can make the feed end of the grain discharging channel 22 connect with the first grain discharging port 131, or make the blocking member 23 block the first grain discharging port 131. The grain distributing assembly 6 can transport the pet grain in the grain storage barrel 1 to the grain discharging channel 22. The vacuum assembly 3 is arranged on the grain storage barrel 1.

When storing pet food, the pet food is placed in the food storage barrel 1, and the vacuum assembly 3 is driven to exhaust the air in the food storage barrel 1, thereby ensuring the sealing of the storage barrel, avoiding the contact between the pet food and the air, and reducing the possibility of the pet food spoiling. When discharging food, the food storage barrel 1 is first connected to the atmosphere to release pressure; then the food discharging assembly is driven to descend to a preset height to avoid the food storage barrel 1, so as to avoid interference with the food storage barrel 1 when the food discharging assembly rotates. Then, the grain discharging assembly is driven to rotate to the second position so that the grain discharging channel 22 is opposite to the grain discharging port, and the grain discharging assembly is driven to rise until the feeding end of the grain discharging channel 22 is connected to the first grain discharging port 131. At this time, the grain discharging channel 22 is connected to the grain storage barrel 1 through the first grain discharging port 131; finally, the grain distributing assembly 6 in the grain storage barrel 1 is driven to rotate, thereby driving the pet food in the grain storage barrel 1 to fall into the pet's food bowl through the first grain discharging port 131 and the grain discharging channel 22, and the grain discharging is completed. After the grain discharging is completed, the grain discharging assembly is driven to descend to the preset height again, and the grain discharging assembly is driven to rotate to the first preset position, and the grain discharging assembly is driven to rise at the same time, so that the blocking member 23 blocks the first grain discharging port 131 again, and the vacuum assembly 3 is driven again to exhaust the air in the grain storage barrel 1 to ensure the sealing of the grain storage barrel 1.

[0045] It should be noted that, since the feed end of the grain outlet channel 22 and the axis of the blocking member 23 are located on the same straight line, the angle that the grain outlet assembly needs to rotate from the first position to the second position is 180°.

[0046] Optionally, the grain discharging mechanism 2 also includes a driving assembly, which includes a first driving member 24 and a rotating shaft 25. The first driving member 24 is arranged on the bearing platform 21, one end of the rotating shaft 25 is connected to the output end of the first driving member 24, and the other end is connected to the grain discharging assembly to drive the grain discharging assembly to rotate and switch between the first position and the second position. The first driving member 24 can drive the rotating shaft 25 to rotate, thereby driving the grain discharging assembly connected to the rotating shaft 25 to rotate, so that the grain discharging assembly switches between the first position and the second position. Optionally, the first driving member 24 is a rotating motor. In this embodiment, the first driving member 24 and the grain discharging assembly are respectively arranged on opposite sides of the bearing platform 21 to avoid interference between the two. Further, two shaft holes are relatively arranged on the bearing platform 21, and the rotating shaft 25 is penetrated through the shaft hole and connected to the grain discharging assembly.

The first sealing member 233 is arranged on the second connecting plate 232. When in the second position, the first sealing member 233 is opposite to the first grain outlet 131. The rising supporting platform 21 can drive the first sealing member 233 to be sealed and inserted into the first grain outlet 131. The first connecting plate 231 can ensure the stability of the connection between the blocking member 23 and the grain outlet 22. The second connecting plate 232 provides an installation space for the first sealing member 233. The first sealing member 233 can seal and block the first grain outlet 131, thereby ensuring the sealing of the grain storage barrel 1. Furthermore, the first sealing member 233 is made of rubber material, which has good sealing performance and low price.

[0048] Optionally, it also includes a mounting seat 4 and a second driving member 5 arranged on the mounting seat 4. The mounting seat 4 is arranged below the grain storage barrel 1. The output end of the second driving member 5 is connected to the bearing platform 21 to drive the bearing platform 21 to rise and fall. The mounting seat 4, as a mounting base, can provide stable support for the second driving member 5. The second driving member 5 can be started to drive the bearing platform 21 to rise and fall, thereby driving the grain discharging assembly on the bearing platform 21 to rise and fall, so as to avoid the grain discharging assembly from interfering with the grain storage barrel 1 during the rotation switching between the first position and the second position.

When the bearing platform 21 is driven to rise and fall, the guide rods 41 can slide up and down along the guide cylinders 211, thereby providing a guiding function for the lifting and lowering of the bearing platform 21, and ensuring the stability of the bearing platform 21 when it is lifted and lowered.

[0050] Specifically, see Figure 1 , Figure 5 and Figure 6 The grain storage barrel 1 includes a barrel cover 11, a first barrel body 12 and a second barrel body 13.

The bottom wall of the first barrel body 12 is provided with a second grain outlet 121 connected to the second barrel body 13. The second grain outlet 121 is staggered with the first grain outlet 131. In this way, the grain storage barrel 1 is divided into two parts, upper and lower. After the grain distribution component 6 is started, the pet grain in the first barrel body 12 first enters the second barrel body 13 through the second grain outlet 121, and then enters the grain outlet channel 22 through the first grain outlet 131, thereby changing the falling direction of the pet grain, realizing the layered falling of the pet grain, avoiding the direct falling of the pet grain, and reducing the occurrence of grain leakage. Preferably, the first barrel body 12 includes a first barrel section and a second barrel section that are connected to each other. The second barrel section is connected to the second barrel body 13. The cross-sectional area of ​​the second barrel section gradually decreases from one end connected to the first barrel section to the other end, thereby providing a guide for the pet food and facilitating the pet food to fall into the second barrel body 13.

[0051] Further, see Figure 4 The grain distributing assembly 6 includes a coaxially connected stirring blade 61 and a grain distributing structure. The stirring blade 61 is arranged on the first barrel 12, and the grain distributing structure is arranged on the second barrel 13.

The third driving member 71 can drive the first transmission gear 73 at its output end to rotate, thereby driving the second transmission gear 74 meshed therewith to rotate, so that the stirring blade 61 connected to the transmission shaft 72 and the grain distributing structure rotate synchronously.

When the grain is discharged, the third driving member 71 is intermittently started, the grain distribution structure and the stirring blade 61 rotate intermittently, and the pet food in the first barrel 12 enters a certain grain distribution channel through the second grain outlet 121. When the grain distribution channel rotates to be opposite to the first grain outlet 131, the pet food in the grain distribution channel can fall into the grain outlet channel 22, thereby dividing the discharged grain into two sections, preventing the pet food from falling directly, and reducing the occurrence of grain jamming.
