Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] See appendix Figures 1 to 16 A pet feeder, comprising:

[0050] The base 1 has a mounting groove 10 and an outlet 11 that connects to the mounting groove 10 on its top.

[0051] The snap-fit ​​mechanism 2 is installed inside the base 1, and one end of the snap-fit ​​mechanism 2 can extend into the mounting groove 10;

[0052] Grain hopper 3, with a first grain outlet 30 on the lower side of grain hopper 3;

[0053] The chuck 4 is connected to the bottom of the grain hopper 3. The chuck 4 has a second grain outlet 40 at the position corresponding to the first grain outlet 30. The chuck 4 can be inserted into the mounting groove 10 and the second grain outlet 40 is aligned with the outlet 11. The chuck 4 also has a fastening groove 41 on both sides. The fastening mechanism 2 can be inserted into the fastening groove 41 for fastening.

[0054] The sealing mechanism 5 includes a rotating member 50, a connecting channel 51 disposed on the rotating member 50, and a sealing plug 52 movable on the rotating member 50. The rotating member 50 is rotatably mounted on the chuck 4. Rotating the rotating member 50 can cause the connecting channel 51 to connect the first grain outlet 30 and the second grain outlet 40 or cause the sealing plug 52 to close the first grain outlet 40.

[0055] The drive mechanism 6 is installed inside the base 1 and is driven by the sealing mechanism 5 to drive the rotating part 50 to rotate or to raise and lower the sealing plug 52.

[0056] Specifically, a vacuum-sealed top cover can be detachably installed on the upper part of the feed hopper. A vacuum extraction device can be installed inside the top cover, chuck, or base. The chuck is bolted to the feed hopper, and the sealing mechanism is installed on the side of the chuck facing the feed hopper, allowing for easy disassembly of both the sealing mechanism and the feed hopper. When cleaning the feed hopper, first, open the vent to allow outside air to enter, removing the negative pressure inside. Then, release the chuck using the locking mechanism, remove the feed hopper and chuck assembly, and then remove the chuck separately (this also releases the seal on the first feed outlet), allowing the feed hopper to be cleaned independently. This design combines sealing and easy disassembly, making the pet feeder easier to clean. The drive mechanism can rotate the rotating parts, while the sealing plug can be raised and lowered using either a motor or a mechanical mechanism.

[0057] Furthermore, the drive mechanism 6 includes a first rotating shaft 61, the rotating component 50 includes a rotating sleeve 500 and a connecting plate 501 disposed on the rotating sleeve 500, the rotating sleeve 500 is detachably mounted on the first rotating shaft 61, the connecting channel 51 is connected to the rotating sleeve 500 and the rotating sleeve 500, the connecting plate 501 and the connecting channel 51 are integrally formed, the sealing plug 52 is movably disposed on the connecting plate 501 and the central axis rotation radius of the connecting channel 51 is the same as the central axis rotation radius of the sealing plug 52.

[0058] Specifically, the drive mechanism includes a power element for driving the first rotating shaft to rotate; while the base contains related control and energy components for controlling the drive mechanism's operation, such as driving and shutting it down. The rotation radius of the central shaft of the connecting channel 51 is the same as that of the central shaft of the sealing plug 52, so that after the rotating part rotates to a designated position, the connecting channel or the sealing plug can fit the position and shape of the first and second grain outlets.

[0059] Furthermore, in this embodiment, the lifting and lowering movement of the sealing plug does not require additional power; instead, the lifting and lowering action of the sealing plug can be performed simultaneously with the rotation of the rotating component. Specifically, the upper side of the connecting plate 501 is provided with a first inclined slider 5011, and the lower side of the sealing plug 52 is provided with an inclined groove 520. The sealing plug 52 is located above the connecting plate 501, and the first inclined slider 5011 moves within the inclined groove 520.

[0060] A guide groove 5010 is provided through the connecting plate 501, and a guide post 521 that penetrates the guide groove 5010 is also connected to the sealing plug 52;

[0061] The lower side of the connecting plate 501 is provided with a second inclined slider 5012. The first inclined slider 5011 and the second inclined slider 5012 are inclined in opposite directions. The guide post 521 is provided with a slider 522 at one end below the connecting plate 501. The slider 522 and the second inclined slider 5012 are slidably connected to each other.

[0062] The sealing plug 52 is also provided with a platform 523, and the chuck 4 is provided with a first limiting boss 42 and a second limiting boss 43. By rotating the rotating member 50 and making the platform 523 abut against the first limiting boss 42, the sealing plug 52 can slide up along the first inclined slider 5011 and block the first grain outlet 30. By rotating the rotating member 50 and making the platform 523 abut against the second limiting boss 43, the slider 522 can descend along the second inclined slider 5012 and the sealing plug 52 can be set to fit against the connecting plate 501.

[0063] Specifically, the top of the sealing plug is soft and elastic. The lifting power of the sealing plug is provided by the interaction between the first inclined slider and the inclined groove, while the lowering power is provided by its own weight and the interaction between the second inclined slider and the slider. Furthermore, the upward movement of the sealing plug also serves to press and seal the first grain outlet. The guide groove and guide post are used to limit the movement distance of the sealing plug on the connecting plate and to prevent the sealing plug from detaching from the connecting plate. More specifically, the structures of the first and second inclined sliders are shown in the attached figure. Figure 11 , 12 As shown in Figure 13, the first limiting protrusion is located near the second grain outlet. When the abutment presses against the first limiting protrusion, the sealing plug rises and does not stop the first grain outlet; when the abutment presses against the second limiting protrusion, the connecting channel connects the first grain outlet and the second grain outlet.

[0064] Furthermore, the sealing plug 52 is also sleeved on the rotating sleeve 500, and the connecting plate 501 is also provided with a positioning boss 5013, and the sealing plug 52 is provided with a positioning groove 524. When the sealing plug 52 is attached to the connecting plate 501, the positioning boss 5013 is located in the positioning groove 524, which is used to lock the position of the sealing plug and prevent the sealing plug from shaking randomly.

[0065] Furthermore, the chuck 4 is provided with a sliding groove 44 arranged around the circumference of the first rotating shaft 61, and a sliding boss 510 is provided on the lower side of the connecting channel 51. Both the sliding boss 510 and the slider 522 are located within the sliding groove 44. Specifically, the sliding groove is used to limit and stabilize the rotational position of the rotating component, and to reserve sufficient space for the lifting and lowering of the guide rod and the slider.

[0066] Furthermore, the locking mechanism 2 includes two locking rods 20, an elastic element 21, and a pusher 22. The two locking rods 20 are symmetrically arranged on both sides of the base 1. The middle part of the locking rod 20 is rotatably connected to the base 1. The first end of the locking rod 20 can extend into the mounting groove 10 and lock onto the fastening groove 41. The second ends of the two locking rods 20 are connected to each other through the elastic element 21. The pusher 22 is slidably arranged on the base 1 and is drivenly connected to the second ends of the two locking rods 20 to drive the second ends of the two locking rods 20 to move closer to each other.

[0067] Specifically, both levers rotate on a horizontal plane, pushing the pusher to slide on the base, thereby causing the second ends of the two levers to move closer to each other, which in turn causes the first ends of the two levers to move away from each other. During this process, the first ends of the two levers will disengage from the locking groove, thereby releasing the lock on the grain hopper and the chuck.

[0068] Additionally, the pusher has a first inclined portion on one side of its base, and the second end of the locking rod has a second inclined portion, with the first and second inclined portions slidably connected. Moving the pusher causes the first inclined portion to move toward the second inclined portion, simultaneously squeezing the second inclined portion away from the first inclined portion. In this embodiment, this manifests as the second ends of the two locking rods moving closer together. However, if no external force subsequently drives the pusher to reset, the second inclined portion remains locked in position by the first inclined portion. The two ends of the first elastic member are respectively connected to the second ends of the two locking rods, providing power for the reset swing of the two locking rods after the pusher is pushed back to reset by an external force. This design allows the user to simultaneously use both hands to lift the grain container after the two locking rods have unlocked the chuck and grain container, preventing the chuck and grain container from being relocked due to the locking rods resetting on their own.

[0069] Furthermore, the grain hopper 3 is also equipped with a grain dispensing mechanism 7, which includes:

[0070] The hopper 70 is installed inside the grain hopper 3, and the hopper 70 is provided with an upper cavity 701 and a lower cavity 702. The upper cavity 701 is connected to the inside of the grain hopper 3, and the lower cavity 702 is connected to the first grain outlet 30. The upper cavity 701 and the lower cavity 702 are connected through an inlet 703, and the inlet 703 and the first grain outlet 30 are staggered.

[0071] Loosening component 71 is rotatably installed in the upper cavity 701;

[0072] The discharge component 72 is rotatably installed in the lower cavity 702. Multiple material distribution rods 720 are evenly distributed around the circumference of the discharge component 72. The space between adjacent material distribution rods 720 is formed. The material distribution rods 720 are provided with upwardly extending scraper combs 721. The scraper combs 721 are made of elastic material.

[0073] The drive mechanism 6 also includes a second rotating shaft 62. The first rotating shaft 61 and the second rotating shaft 62 are coaxially arranged, and the second rotating shaft 62 penetrates the first rotating shaft 61 and the rotating sleeve 500. The second rotating shaft 62 also penetrates the hopper 70 and extends into the upper cavity 701, so that the loosening part 71 and the discharge part 72 are both installed on the second rotating shaft 62.

[0074] Specifically, the area between two adjacent feed dispensing rods constitutes a feed-fixing space, with each space containing roughly the same amount of pet food. The upper chamber opens upwards, and the lower chamber opens downwards, ensuring neither is sealed and facilitating subsequent cleaning of the feed hopper. The first feed outlet and inlet are staggered to prevent food particles from the upper chamber from falling directly from the inlet, passing through the lower chamber, and exiting from the first feed outlet. The feed outlet, feed dispensing rods, and scraper comb are integrally molded structures, all made of elastic material, as is the loosening component. In this embodiment, the elastic material is one with good flexibility and mechanical properties, such as rubber or PU. The upward-extending scraper comb makes the side of the dispensing part near the inlet soft and more elastically deformable. This allows it to scrape away pet food stuck in the food inlet to a certain extent. If it encounters pet food that cannot be scraped away, the scraper comb itself elastically deforms and passes over the stuck food during movement. This prevents the scraper comb from wearing down due to long-term hard impacts and also prevents the food from being crushed, leading to the accumulation of powder in the lower chamber. This is also suitable for situations where the food storage space is full. The dispensing rod used for dispensing food also functions as a comb and prevents the dispensing part from hard impacting the pet food, effectively improving its service life.

[0075] On the other hand, the drive mechanism has two power units, which are used to drive the first rotating shaft and the second rotating shaft respectively. The coaxial series connection structure of the first rotating shaft and the second rotating shaft can ensure that the transmission of the sealing mechanism by the first rotating shaft and the transmission of the loosening and discharging parts by the second rotating shaft do not interfere with each other.

[0076] Furthermore, the hopper 70 is transparent or partially transparent, and the base 1 is also equipped with an infrared sensor 12. The infrared sensor 12 is used to detect the inside of the upper cavity, so as to facilitate the observation of the internal condition during later cleaning and to facilitate the detection of the amount of grain in the upper cavity.

[0077] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. Although embodiments of the invention have been shown and described, those skilled in the art will recognize that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
