Modes for Carrying Out the Invention

[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0035] It should be understood by those skilled in the art that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0036] As shown in Figures 1 to 10, a pet feeder using a feeder food dispensing mechanism disclosed herein comprises a grain bin, a feeding tray 4 and a feeder food dispensing mechanism. The feeder food dispensing mechanism delivers food from the grain bin to the feeding tray 4.

[0037] In this example, the food outlet 15 of the food outlet mechanism of the feeder is located at the entrance of the feeding tray 4. The food outlet 15 and the entrance are distributed up and down. The food falling from the food outlet 15 falls into the feeding tray 4, and the pet eats the food through the feeding tray 4.

[0038] As shown in Figures 9 and 10, the granary includes a grain barrel 1 and a base 2. The grain barrel 1 and the base 2 are detachably connected up and down. The base 2 is arranged on the upper side of the transverse section 3. After the grain barrel 1 and the base 2 are connected, the outlet of the grain barrel 1 is connected to the grain outlet 5 up and down.

[0039] The grain barrel 1 and the base 2 are detachably connected up and down, which makes it easy to remove and clean the grain barrel 1. When the grain barrel 1 is removed, the grain outlet 5 is also exposed, which makes it easy to clean the grain outlet 5.

[0040] In this example, as shown in FIG9 , a vertical outlet 17 is provided at the lower end of the grain barrel 1 .

[0041] As shown in FIG3 , the feeder's grain discharging mechanism includes a grain discharging channel, which includes at least a transverse section 3 with a grain dropout opening 5 disposed on its upper side. The mechanism also includes a reciprocating grain pusher 6, which is sleeved and mated with the transverse section 3 and is used to push grain in the transverse section 3 forward; a grain discharging baffle 7, which is located at the exit of the grain discharging channel or in the portion between the exit of the grain discharging channel and the grain dropout opening 5. A grain storage chamber 8 is formed between the grain discharging baffle 7 and the reciprocating grain pusher 6. When the reciprocating grain pusher 6 pushes the grain in the transverse section 3 forward, the grain discharging baffle 7 is pushed open by the grain to discharge the grain. The exit of the grain discharging channel is the grain discharging opening 15.

[0042] Regarding the arrangement of the grain discharge baffle 7, on the one hand, the grain discharge baffle 7, the transverse section 3, and the reciprocating grain pusher 6 together form a temporary grain storage chamber 8. When the reciprocating grain pusher 6 reciprocates, the amount of grain discharged is controlled by the reciprocating stroke. Regarding the spacing between the lower end of the grain discharge baffle 7 and the inner bottom surface of the grain discharge port 15, it is set according to the type of grain. If the grain particles are large, the spacing height can be larger, and if the grain particles are small, the spacing height can be smaller.

[0043] Regarding the arrangement of the grain discharge baffle 7, on the other hand, as shown in Figures 3 and 4, the upper end of the grain discharge baffle 7 is rotatably connected to the base 2. A torsion spring can be provided at the upper end of the grain discharge baffle 7 to provide a restoring force, or the principle of gravity can be used to provide a restoring force for the grain baffle. This restoring force provides the grain supply baffle with a certain resistance to opening. In this way, when the reciprocating grain pusher 6 is not pushed forward, the grain accumulated in the grain barrel 1 is reduced from pushing the grain supply baffle open due to its own gravity, resulting in a large amount of grain leakage. In short, the main force for pushing the grain supply baffle open comes from the force generated by the reciprocating grain pusher 6 when pushing the grain in the transverse section 3 forward.

[0044] Although the upper end of the grain discharge baffle 7 is rotatably connected as an example, other structures may also be used, such as a side end of the grain discharge baffle 7 rotatably connected, or even a lower end of the grain discharge baffle 7 rotatably connected. Any grain discharge baffle 7 that is applicable to the present disclosure is acceptable.

[0045] In this example, as shown in Figures 3, 8, and 11, the grain discharge passage is formed by a transverse section 3, the front end of which is open as a grain discharge port 15. The upper side of the front end of the transverse section 3 is a grain drop port 5. A grain discharge baffle 7 is provided at the grain drop port 15, located behind the grain drop port 5 and movably cooperating with a grain pusher 6. This allows the grain discharge passage to be very short, which facilitates a smaller overall structural volume. Furthermore, the length of the grain storage chamber 8 is also shorter, which helps reduce the capacity of the grain storage chamber 8 and the amount of exposed grain. In other words, it is better to store the grain primarily within the grain barrel 1.

[0046] There are many structures that drive the reciprocating grain pushing head 6 to move back and forth, which cannot be listed exhaustively. All structures that are applicable to the present disclosure can be applied to the present disclosure.

[0047] In this example, the structure that drives the reciprocating grain pushing head 6 to move back and forth adopts a crank 10 motion structure. The crank 10 motion structure is connected to the reciprocating grain pushing head 6, and the crank 10 motion structure reciprocates to drive the reciprocating grain pushing head 6 to move back and forth.

[0048] Furthermore, as shown in Figures 4 and 6, the crank 10 motion structure includes an electric motor 9 and a crank 10. The electric motor 9 is laterally arranged on one side of the reciprocating grain pusher 6 and is fixedly mounted on the transverse section 3 or the base 2. The reciprocating grain pusher 6 is provided with a vertical mating portion 11 with a side opening. The crank 10 is inserted from the side into the vertical mating portion 11 for mating. The electric motor 9 rotates continuously to drive the crank 10 to reciprocate. The reciprocating motion of the crank 10 drives the reciprocating grain pusher 6 to reciprocate via the vertical mating portion 11. This is conducive to a smaller structure. In addition, the electric motor 9 is continuously operated without the need for reversing, which is conducive to simplifying the drive circuit of the electric motor 9 and has a high drive efficiency, which is conducive to ensuring grain output efficiency.

[0049] In this example, as shown in Figures 3, 4, 5 and 7, the vertical fitting portion 11 is configured as a vertical hole, but may also be a vertical slot.

[0050] In order to further reduce the volume, as shown in Figures 4, 5, 6 and 7, a receiving groove 12 is provided on one side of the reciprocating grain pushing head 6, the side opening of the vertical matching part 11 is located in the receiving groove 12, and at least a part of the electric motor 9 is received in the receiving groove 12.

[0051] In order to accommodate at least part of the electric motor 9 in the accommodating groove 12 , i.e., to insert it into the accommodating groove 12 , as shown in FIG8 , the transverse section 3 is adaptively provided with a side connecting opening 18 on the side, and the electric motor 9 enters the accommodating groove 12 through the side connecting opening 18 .

[0052] As can be seen from the above, the food discharging mechanism of the feeder disclosed herein has a very compact structure and a small size.

[0053] In some embodiments, as shown in Figures 3, 4, and 5, the front end of the reciprocating grain pusher 6 is provided with a trumpet-shaped grain pushing peripheral portion. This allows for better grain pushing, reduces grain jamming when the grain is thin, and allows for smoother grain delivery. Overall, this helps improve the compatibility of the present disclosure.

[0054] In some embodiments, as shown in Figures 7, 8, and 11, the transverse section 3 is a pipe with a rectangular or trapezoidal cross-section, and the trumpet-shaped grain pushing peripheral portion is composed of grain pushing pieces 13 located on both sides and the bottom of the pipe.

[0055] In this example, a trapezoidal surface is used, and the bottom edge of the trapezoidal surface is located on the upper side of the pipe, which results in a trapezoidal surface. This is conducive to a larger opening of the grain drop port 5, ensuring that the grain enters the transverse section 3. In addition, the trumpet-shaped grain pushing portion is composed of the grain pushing pieces 13 located on both sides and the lower side of the pipe, but the grain pushing piece 13 is not provided on the upper side of the pipe. In this way, the grain pushing piece 13 is prevented from pushing the grain upward, or even causing the grain to get stuck, and the grain pushing piece 13 is also easily damaged.

[0056] The grain pushing piece 13 can be made of silica gel, which is conducive to elasticity and hygiene.

[0057] In some embodiments, as shown in Figures 4, 5, and 11, the grain pushing pieces 13 on both sides and the lower side are connected to form a U-shaped piece 14, and the U-shaped piece 14 is connected to the front end of the reciprocating grain pushing head 6. This facilitates production.

[0058] In some embodiments, as shown in Figures 2, 3, 8, 9, and 11, the transverse section 3 is a U-shaped slotted tube with an upper opening. The length of the outlet of the grain barrel 1 in the front-to-back direction is shorter than the upper opening of the U-shaped slotted tube. The outlet of the grain barrel 1 is connected to the upper opening of the U-shaped slotted tube. The reciprocating grain pusher 6 cooperates with the U-shaped slotted tube and is located behind the outlet of the grain barrel 1. A seal 16 is provided between the reciprocating grain pusher 6 and the grain barrel 1. This simplifies the structure and facilitates manufacturing. In addition, the reciprocating grain pusher 6 and the grain drop port 5 are exposed by removing the grain barrel 1, making it easier to clean.

[0059] In this example, as shown in Figures 3 and 11, Figure 11 is used to indicate the position of the seal 16. The seal 16 is actually connected to the lower end of the grain barrel 1. When the grain barrel 1 is taken out, the seal 16 is removed together with the grain barrel 1.

[0060] In order to better match the reciprocating motion of the reciprocating grain pushing head 6, the sealing sheet of the sealing member 16 is tilted as shown in FIG3. When the reciprocating grain pushing head 6 retracts, the sealing sheet scrapes off the grain on the top surface of the reciprocating grain pushing head 6 like a scraper.

[0061] When understanding the present disclosure, if necessary, the above structure can be understood with reference to other embodiments / drawings, and will not be described in detail here.

[0062] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
