[0022] For ease of understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this invention belongs. The terms used in this specification and in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0024] Example 1

[0025] like Figure 1 and Figure 3 As shown, this embodiment provides a food dispensing device for a bird feeder, comprising a feeding tray 1 and a driver 2. The feeding tray 1 is provided with an assembly hole 11. A food storage cylinder 3 is provided at the bottom of the feeding tray 1. The food storage cylinder 3 is provided with a food outlet 31 communicating with the assembly hole 11. A material pusher 4 is provided in the food storage cylinder 3.

[0026] The driver 2 is used to drive the pushing member 4 to move so as to push the bird feed contained in the grain storage barrel 3 out of the grain outlet 31 .

[0027] The top of the grain storage barrel 3 passes through the mounting hole 11 and protrudes from the feeding tray 1. An annular frustum 5 is sleeved around the outer periphery of the top of the grain storage barrel 3. Specifically, the grain outlet 31 is set higher than the height of the mounting hole 11, so that the top of the grain storage barrel 3 protrudes slightly relative to the feeding tray 1. This allows the bird feed flowing out of the grain outlet 31 to flow divergently toward the feeding tray 1, resulting in more uniform feed discharge and preventing accumulation. Preferably, the mounting hole 11 is located in the center of the feeding tray 1 to ensure uniform feed discharge.

[0028] Preferably, the grain storage hopper 3 is equipped with a detection mechanism for detecting the amount of bird feed remaining. The detection mechanism can be electrically connected to the smart terminal. When the amount of bird feed is too low, the user is reminded to refill the bird feed. When the amount of bird feed reaches the maximum level during refilling, the user is reminded to stop refilling the bird feed. The detection mechanism can be a pressure sensor located on the pusher 4, which directly detects the weight of the bird feed and determines the amount of bird feed in the grain storage hopper 3 based on the weight. Alternatively, the detection mechanism can be a photoelectric sensor located at the upper and lower ends of the grain storage hopper 3, which determines the amount of bird feed in the grain storage hopper 3 based on the volume. To determine whether the feeding tray 1 needs to be replenished with bird feed, a timed feed dispensing program can be set. When the set time is reached, the driver 2 will activate accordingly, thereby replenishing the feeding tray 1 at the set time. Alternatively, image recognition technology can be used to identify whether the feeding tray 1 is filled with bird feed. Typically, the driver 2 will activate to replenish the feeding tray 1 when the feeding tray 1 is detected to be at or near the empty space.

[0029] The pusher 4 and the bottom end of the grain storage barrel 3 cooperate to form a push chamber 7. The air pump 21 is electrically connected to an air pressure sensor 23, and the detection end of the air pressure sensor 23 is disposed in the push chamber 7. The driver 2 also includes a controller 24. The air pump 21 and the air pressure sensor 23 are electrically connected to the controller 24. The controller 24 controls the operation or stop of the air pump 21. The air pressure sensor 23 detects the air pressure value in the push chamber 7 and feeds it back to the controller 24. The controller 24 converts the air pressure value into a weight value, and the controller 24 determines whether to issue a signal to replenish bird feed based on the weight value.

[0030] Specifically, the controller 2 controls the air pump 21 to work, filling the push chamber 7 with air, allowing the pusher 4 to rise to a height of H. At this time, the air pressure sensor 23 detects the air pressure value in the push chamber 7 and feeds it back to the controller 24. The controller 24 converts the air pressure value into a weight value. The controller 24 determines whether to send a signal to replenish bird feed based on the weight value. The weight value is preset. When the actual feedback weight value is within the set weight value range, a signal to replenish bird feed is sent to the smart terminal. For the detection of height H, a photoelectric sensor can be fixed at a certain position on the inner wall of the grain storage barrel 3, or a movement sensor can be set on the pusher 4 to detect the actual movement height of the pusher 4, which is the height H.

[0031] It is worth mentioning that the air pressure sensor 23 and the controller 24 work together to achieve the purpose of the detection mechanism detecting the amount of bird food. The detection mechanism and the air pressure sensor 23 can be set at the same time to achieve multiple detections, making it more accurate to judge the amount of bird food.

[0032] The pusher 4 slides and seals within the grain storage barrel 3. The driver 2 includes an air pump 21 and a control valve 22. The control valve 22 communicates between the bottom of the grain storage barrel 3 and the air pump 21. Specifically, the shape of the pusher 4 matches the inner wall of the grain storage barrel 3 to ensure a sliding and sealing fit. The pusher 4 divides the inner cavity of the grain storage barrel 3 into an upper cavity and a lower cavity. The upper cavity contains bird feed, and the control valve 22 communicates with the lower cavity, which is the push cavity 7. During operation, the air pump 21 is activated, and the gas is filled into the lower chamber through the control valve 22, thereby pushing the pusher 4 to slide upward and away from the bottom surface of the grain storage barrel 3, so that the bird food is pushed out from the grain outlet 31. At this time, the control valve 22 is equivalent to a one-way valve, and the gas can only flow into the lower chamber; after the bird food is replenished, the control valve 22 will be reversed to discharge the gas in the lower chamber, so that the pusher 4 and the bottom surface of the grain storage barrel 3 are against each other, and the bird food will not always be in the grain outlet 31, preventing birds from directly pecking at the bird food in the grain storage barrel 3. It should be noted that the driver 2 can also be a cylinder, a hydraulic cylinder and other driving mechanisms, which can make the pusher 4 move along the axial direction of the grain storage barrel 3 to push out the bird food. The structure thereof will not be described in detail here. Of course, the pusher 4 can also be a spiral conveying rod, and the driver 2 uses a motor, which can also achieve the purpose of pushing out the bird food. The structure thereof will not be described in detail here.

[0033] The present invention also includes a one-way opening and closing mechanism 6 for opening and closing the grain outlet 31. The one-way opening and closing mechanism 6 includes a support frame 601 connected to the grain outlet 31. A cover plate 602 is slidably connected to the support frame 601. The cover plate 602 is disposed opposite the grain outlet 31 and has a size equal to or larger than the diameter of the grain outlet 31. Specifically, the support frame 601 is provided with a sliding hole 6011, and the cover plate 602 is provided with a sliding rod 6021 that slidably engages with the sliding hole 6011. The sliding rod 6021 is extended along the axial direction of the grain outlet 31, and a limit block 603 is provided at the end of the sliding rod 6021 to engage with the support frame 601. Under normal circumstances, the cover 602 closes the food outlet 31 under the action of gravity, preventing birds from eating the bird food in the food storage barrel 3; when the bird food is pushed upward, the cover 602 will be pushed upward, and the slide rod 6021 will slide relative to the slide hole 6011 until the limit block 603 abuts against the support frame 601, and the bird food can flow out of the food outlet 31 smoothly, so as to smoothly replenish the bird food to the feeding tray 1.

[0034] Example 2

[0035] refer to Figures 4 and 5 As shown, the one-way opening and closing mechanism 6 includes a diverter tube 611 connected to the grain outlet 31. The sidewall of the diverter tube 611 is circumferentially defined with a plurality of diverter openings 6111. The diverter tube 611 is provided with a plurality of one-way doors 612 corresponding to the diverter openings 6111. The top of the one-way doors 612 is rotatably connected to the diverter tube 611, and the bottom of the one-way doors 612 engages with an outer stopper of the diverter tube 611. A retaining edge 613 is provided at the top of the diverter tube 611. The retaining edge 613 has a larger diameter than the diverter tube 611. Under normal circumstances, the one-way door 612 closes the diverter openings 6111 under the action of gravity, thus preventing birds from consuming the bird feed in the grain storage barrel 3. As the bird feed is pushed upward, it passes through the grain outlet 31 and flows into the diverter openings 6111, pushing open the one-way door 612, allowing the bird feed to flow out smoothly and replenish the feeding tray 1.
