Description

Technical Field

[0001] This utility model belongs to the field of pet feeder technology, specifically relating to a feeder outlet structure. Background Technology

[0002] In the pet feeder market, the sealing structure of the dispensing spout is a key factor affecting the preservation quality of the food. Currently, pet feeder dispensing spouts on the market have several defects. Some products lack a cover, leaving the spout completely open after feeding, with no moisture protection, and the food is directly exposed to the air, making it highly susceptible to moisture. Others, while having a cover, rely solely on the cover's own weight to close the dispensing spout. Due to the complexities of actual use, the cover cannot guarantee complete closure after each feeding, resulting in poor moisture protection.

[0003] The main reason for these problems lies in the overly simplistic product design, which fails to adequately consider the importance of moisture protection for the feed and the reliability of the lid's closure. Attempts to solve these problems have encountered numerous difficulties. For example, while increasing the weight of the lid can improve the likelihood of closure to some extent, it affects the overall stability and aesthetics of the feeder; adopting a complex mechanical structure increases costs and the risk of product failure. These problems not only lead to feed spoilage and shorten its shelf life but may also cause pets to become ill from consuming spoiled feed, significantly impacting the user experience. An innovative feed outlet structure is urgently needed to solve these problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a feeder outlet structure that effectively prevents the feed inside the feeder from becoming damp and spoiling by actively closing the outlet cover, significantly extending the feed's shelf life, enabling long-term fully automatic feeding, ensuring pet food quality, maintaining pet health, and improving the user experience.

[0005] Structural composition: The feeder outlet structure of this utility model mainly includes a pusher screw, screw arm, outlet cover, cover rib, cover spring, feed cylinder and outlet, etc.

[0006] Connection and positional relationships: The feed screw is located inside the feed cylinder and can rotate around its own axis. The screw arm is connected to the feed screw. The discharge port cover is installed at the discharge port, and the cover rib is set on the discharge port cover, cooperating with the screw arm. One end of the cover spring is connected to the discharge port cover, and the other end is fixed to the main structure of the feeder, so that the discharge port cover is always subjected to pressure in the closing direction.

[0007] When the feeder begins feeding, the pusher screw starts and rotates. As the screw rotates, the screw arm gradually moves outward until it hits the rib of the discharge port, thus opening the discharge port door and allowing feed to fall out. The screw continues to rotate, and the screw arm gradually retracts, disengaging from the rib of the discharge port door. Under the pressure of the door spring, the discharge port door gradually reduces its opening angle until it is completely closed. Just before the end of the feeding cycle, the screw arm reverses and retracts, pushing any remaining feed around the discharge port door into the feed hopper. Then, under spring pressure, the discharge port door closes completely again, effectively preventing moisture from entering and keeping the feed dry.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] Mainstream products on the market often fail to effectively seal the feed outlet, resulting in the feed remaining dry for only about a week. However, the feed outlet structure of this invention allows the feed to remain dry for up to a month under normal conditions. This not only ensures the quality of the feed throughout the entire feeding cycle and reduces waste, but also significantly lowers the risk of pets getting sick from consuming spoiled feed, thus improving user satisfaction and overall experience with the pet feeder.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1-4 As shown;

[0020] A feeder outlet structure includes a pusher screw 1, a screw arm 2, an outlet cover 3, a cover rib 4, a cover spring 5, a feed cylinder 7, an outlet 8, and a feeder body 9.

[0021] This implementation plan addresses the technical problems existing in the prior art, such as the various defects in the dispensing structure of pet feeders currently on the market, as disclosed in the background section above. Some products lack a cover, leaving the dispensing port completely open after feeding, with no moisture-proof measures, exposing the feed directly to the air and making it highly susceptible to moisture. Others, while equipped with covers, rely solely on the weight of the cover itself to close the dispensing port. Due to the complexity of actual usage scenarios, the cover cannot guarantee complete closure after each feeding, resulting in poor moisture protection. Considering practical use, this problem is clearly real and difficult to solve. Therefore, to address this technical problem, a new dispensing structure for pet feeders is provided.

[0022] like Figure 1-4 As shown in the figure;

[0023] In summary, the feeding screw 1 is located inside the feed cylinder 7 and is rotatable; the screw arm 2 is connected to the feeding screw 1; the discharge port cover 3 is installed at the discharge port 8; the cover rib 4 is provided on the discharge port cover 3 and cooperates with the screw arm 2; one end of the cover spring 5 is connected to the discharge port cover 3, and the other end is fixed to the feeder body 9; the feeder body 9 is provided with a control panel 10; and the bottom of the feeder body 9 is provided with a mounting bracket 11 and a mounting knob 6.

[0024] During feeding, the feed pusher screw 1 rotates, causing the screw arm 2 to push open the door cover rib 4, thus opening the outlet door cover 3, and the feed falls through the outlet 8; the feed pusher screw 1 continues to rotate, the screw arm 2 retracts and disengages from the door cover rib 4, and the outlet door cover 3 closes under the pressure of the door cover spring 5.

[0025] Before the feeding program ends, the rotating arm of the pusher screw 1 reverses and retracts, pushing the feed around the discharge port cover 3 into the feed cylinder 7. Then the discharge port cover 3 is completely closed under the pressure of the cover spring 5.

[0026] The door cover spring 5 provides pressure to the discharge port door cover 3 in the closing direction at all times, ensuring that the discharge port door cover 3 remains closed when not feeding.

[0027] The 8-structured discharge port is designed to prevent feed from getting damp and spoiling, thus extending the feed's shelf life within the feeder.

[0028] Installation and Assembly: During the manufacturing process, the feed screw and screw arm are precision machined to ensure dimensional accuracy and mechanical properties. The feed screw is installed inside the feed cylinder to ensure smooth and stable rotation. A discharge port cover is installed at the discharge port, ensuring the cover ribs precisely align with the screw arm. One end of the cover spring is securely fixed to the discharge port cover, and the other end is installed in a suitable position on the feeder body, ensuring the spring provides stable closing pressure. Finally, the entire discharge port structure is assembled with other feeder components, such as the control panel, mounting knobs, and mounting brackets, to form a complete pet feeder.

[0029] Usage: When using the feeder, the user first loads the feed into the feed hopper and sets the feeding time and amount via the control panel. When the set feeding time arrives, the feeder starts, the pusher screw begins to rotate, and the feed is dispensed according to the working principle described above. Throughout the feeding process, the user does not need to worry about the outlet sealing; simply check the remaining feed in the hopper periodically and replenish it as needed. After the feeder has been running for a period of time, the user can clean and maintain the outlet structure as needed to ensure all components are functioning properly.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
