Description

Technical Field

[0001] This utility model relates to the technical field of feeding machines, and more specifically, to a discharge port cover assembly and a pet feeder. Background Technology

[0002] With the increasing number of pet owners, they are not only concerned about their pets' food and water, but also about their dietary health. Although many automatic feeders have appeared on the market, most of these devices can only perform basic functions such as timed food dispensing and remote food dispensing. However, these automatic feeders cannot heat or sterilize food, and are not suitable for fresh canned food or homemade pet meals that require refrigeration. Pets are prone to gastrointestinal problems if they eat cold food directly.

[0003] In the prior art, Chinese patent CN115517190B discloses a steam-heated automatic pet feeder, including a casing, a mixing tank inside the casing, a mixing module inside the mixing tank for mixing feed, a conveying module connected to the mixing module for discharging feed out of the mixing tank, and a steam heating module inside the casing that releases steam into the mixing tank. Through the combined use of the steam heating module and the mixing module inside the mixing tank, the high temperature of steam is used to thoroughly sterilize and cook the feed, effectively killing bacteria and preventing pets from eating undercooked feed. However, the feeder's cover is directly over the discharge port and is fixedly connected to it. This non-removable design makes cleaning difficult, and over time, food residue clumps together, breeding bacteria and negatively impacting the pet's health. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where the discharge port cover assembly cannot be disassembled and is prone to bacterial growth. This invention provides a discharge port cover assembly and a pet feeder that are easy to disassemble and clean, do not easily breed bacteria, and can protect the intestinal health of pets.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A discharge port cover assembly is provided, which is disposed on a discharge pipe support and includes a baffle and a pipe cover. The baffle is rotatably connected to the pipe cover. The pipe cover has a discharge port that communicates with the discharge pipe support. The discharge pipe support has a snap-fit ​​groove, and the inner wall of the pipe cover has a protrusion that snaps into the snap-fit ​​groove.

[0007] The discharge port cover assembly of this utility model achieves a detachable connection between the discharge port cover assembly and the discharge pipe support by engaging a protrusion on the inner wall of the cover with a snap-fit ​​groove on the discharge pipe support. During use, the cover can be quickly installed by simply snapping it onto the discharge pipe support. Then, the baffle can be rotated to allow food to flow smoothly out of the discharge port inside the cover. The detachable discharge port cover assembly is easy to remove for thorough cleaning after use, preventing food residue from accumulating and breeding bacteria, thereby improving hygiene and protecting pet health.

[0008] Furthermore, the snap-fit ​​groove includes a horizontal channel and a vertical locking section that are interconnected. The horizontal channel is located at the end of the discharge pipe support, and the vertical locking section is perpendicular to the horizontal channel. The boss enters the snap-fit ​​groove through the horizontal channel, and then the pipe cover is rotated, causing the boss to enter the vertical locking section that is perpendicular to the horizontal channel. This allows the boss to be stably snapped into the snap-fit ​​groove, preventing it from falling off during use. The process can be completed simply by rotating the metal part, simplifying the assembly and disassembly process.

[0009] Furthermore, the horizontal channel and the boss are in a clearance fit, and the horizontal channel has a chamfer at the end near the pipe cap. Maintaining a clearance fit between the boss and the horizontal channel, while simultaneously providing a chamfer at the end of the horizontal channel near the pipe cap, facilitates the boss's quick positioning to the installation position and smooth entry into the snap-fit ​​groove.

[0010] Furthermore, the pipe cover is provided with a rotating connecting part protruding from the pipe cover, and the baffle is engaged with the rotating connecting part to control the opening and closing state of the discharge port. The rotating connecting part protrudes from the pipe cover, and by engaging the baffle with the rotating connecting part, the baffle can rotate around the rotating connecting part as the center, thereby adjusting the opening degree of the discharge port inside the pipe wall or keeping it closed.

[0011] Furthermore, the rotating connecting part is provided with a snap-fit ​​post, which is perpendicular to the rotating connecting part, and the baffle is provided with a rotating part that cooperates with the snap-fit ​​post. The rotating part on the baffle cooperates with the snap-fit ​​post on the rotating connecting part, forming a side-opening structure between the baffle and the pipe cover, allowing the baffle to be manually opened and closed to change the opening and closing state of the discharge port.

[0012] Furthermore, the snap-fit ​​post is cylindrical and has mutually parallel reference planes. The axis of the pipe cap is perpendicular to the reference planes, and the rotating part is an open arc shape. By flattening both ends of the cylindrical snap-fit ​​post to form reference planes that are perpendicular to and parallel to the axis of the pipe cap, it is easy to snap the snap-fit ​​post into the open arc-shaped rotating part. Simply align the two ends of the open arc with the two reference planes, which facilitates quick installation and removal of the baffle.

[0013] Furthermore, it also includes a sealing ring. The baffle has a mounting groove, and the sealing ring is fitted onto the mounting groove and has an interference fit with the discharge port. When the discharge port cover is closed, the sealing ring abuts against the inner wall of the cover and has an interference fit, thereby achieving a stable seal of the discharge port cover and preventing the internal high-temperature steam from flowing out and scalding the user.

[0014] Furthermore, the bosses are arc-shaped and evenly distributed around the circumference of the pipe cover. Multiple arc-shaped bosses are evenly distributed around the inner wall of the pipe cover, improving connection reliability. Damage to a single boss does not affect use and prevents misalignment during installation.

[0015] This utility model also provides a pet feeder, including a housing, a cooking chamber disposed within the housing for heating food, a discharge pipe support communicating with the cooking chamber, a conveying component disposed within the cooking chamber for conveying food to the discharge port, and a discharge port cover assembly, wherein the discharge port cover assembly is snapped into the discharge pipe support.

[0016] This utility model of a pet feeder allows users to simply put pet food, such as chilled canned food, into the cooking chamber for heating. Once cooked, the food falls into the conveying assembly, which then transports it to the outlet. As the food moves, it passes through the outlet support, which opens the outlet cover and flows out of the outlet, eliminating the need for manual operation.

[0017] Furthermore, the conveying assembly includes a motor disposed within the housing, a conveying cylinder communicating with the cooking cavity, a stirring rod disposed within the cooking cavity and connected to the motor, and a conveying screw disposed within the conveying cylinder. The conveying cylinder is disposed within the discharge pipe support, and the conveying screw is connected to the stirring rod, which is equipped with multiple sets of stirring blades. When the motor drives the stirring rod to rotate, the food is stirred and broken up by the stirring blades in the cooking cavity. After the food falls into the conveying cylinder, the motor drives the conveying screw to rotate, gradually pushing the food out of the conveying cylinder, allowing the food to push open the discharge port cover assembly, thereby achieving automatic opening of the cover.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The outlet cover and outlet bracket are detachably connected, which makes it easy to disassemble and clean, avoids the growth of bacteria, and protects the pet's intestinal health;

[0020] 2. It has a good sealing effect, and internal steam is not easily leaked during cooking, thus avoiding scalding the user;

[0021] 3. The material is pushed to the outlet by the conveying screw, and the outlet cover will be automatically opened without manual operation. Attached Figure Description

[0034] Example 1

[0035] This embodiment is the first embodiment of the discharge port cover assembly, which is installed on the discharge pipe support 300 and includes a baffle 100 and a pipe cover 200. The baffle 100 and the pipe cover 200 are rotatably connected. The pipe cover 200 is provided with a discharge port 210 that communicates with the discharge pipe support 300. The discharge pipe support 300 is provided with a snap-fit ​​groove 310. The inner wall of the pipe cover 200 is provided with a boss 220 that snaps into the snap-fit ​​groove 310.

[0036] like Figure 1 As shown, in this embodiment, the discharge port cover assembly is detachably connected to the discharge pipe support 300 by engaging the protrusion 220 on the inner wall of the pipe cover 200 with the snap-fit ​​groove 310 on the discharge pipe support 300. During use, the pipe cover 200 and the discharge pipe support 300 can be snapped together for quick installation. Then, the baffle 100 is rotated to allow the food to flow smoothly out of the discharge port 210 inside the pipe cover 200. The detachable discharge port cover assembly is easy to remove for thorough cleaning after use, preventing food residue from accumulating and breeding bacteria, thereby improving hygiene and protecting the pet's health.

[0037] like Figure 1 As shown, the snap-fit ​​groove 310 includes a horizontal channel 311 and a vertical locking section 312 that are interconnected. The horizontal channel 311 is located at the end of the discharge pipe support 300, and the vertical locking section 312 is perpendicular to the horizontal channel 311. The boss 220 enters the snap-fit ​​groove 310 from the horizontal channel 311. Then, the pipe cover 200 is rotated, which drives the boss 220 into the vertical locking section 312 that is perpendicular to the horizontal channel 311, so that the boss 220 can be stably snapped into the snap-fit ​​groove 310, preventing it from falling off during use. At the same time, it can be completed by simply rotating, which simplifies the disassembly and assembly process.

[0038] The horizontal channel 311 and the boss 220 are in clearance fit, and the end of the horizontal channel 311 near the pipe cover 200 is chamfered. The clearance fit between the boss 220 and the horizontal channel 311, and the chamfer at the end of the horizontal channel 311 near the pipe cover 200, facilitates the quick positioning of the boss 220 to the installation position and smooth entry into the snap-fit ​​groove 310.

[0039] like Figure 4 , Figure 5 , Figure 6 As shown, the discharge port cover assembly in this embodiment also includes a sealing ring 120. The baffle 100 has a mounting groove 130, and the sealing ring 120 is fitted onto the mounting groove 130 with an interference fit to the discharge port 210. When the discharge port 210 cover is closed, the sealing ring 120 abuts against the inner wall of the pipe cover 200 with an interference fit, thereby achieving a stable seal of the discharge port 210 cover and preventing the outflow of high-temperature steam from scalding the user.

[0040] like Figure 2 As shown, the bosses 220 are arc-shaped and evenly distributed around the circumference of the pipe cover 200. Multiple arc-shaped bosses 220 are evenly arranged around the inner wall of the pipe cover 200 to improve connection reliability. Damage to a single boss 220 does not affect use and can prevent misalignment during installation.

[0041] Example 2

[0042] This embodiment is a second embodiment of the discharge port cover assembly. Similar to the first embodiment, the difference lies in that the pipe cover 200 has a rotating connecting portion 230 protruding from it. The baffle 100 is engaged with the rotating connecting portion 230 to control the opening and closing state of the discharge port 210. The rotating connecting portion 230 protrudes from the pipe cover 200. By engaging the baffle 100 with the rotating connecting portion 230, the baffle 100 can rotate around the rotating connecting portion 230 as its center, thereby adjusting the opening degree of the discharge port 210 inside the pipe wall or maintaining its closed state. In this embodiment, the rotation plane of the baffle 100 can be parallel to the axis of the pipe cover 200, i.e., a side-opening baffle 100, or it can be perpendicular to the axis of the pipe cover 200, i.e., a rotating structure. By changing the rotation angle of the baffle 100, the opening and closing degree of the discharge port 210 can be changed.

[0043] like Figure 1 , Figure 3As shown, the rotating connecting part 230 is provided with a snap-fit ​​post 240, which is perpendicular to the rotating connecting part 230. The baffle 100 is provided with a rotating part 110 that cooperates with the snap-fit ​​post 240. The rotating part 110 on the baffle 100 cooperates with the snap-fit ​​post 240 on the rotating connecting part 230, and the baffle 100 and the pipe cover 200 form a side-opening structure, which can be manually opened and closed to change the opening and closing state of the discharge port 210.

[0044] like Figure 3 As shown, the snap-fit ​​post 240 is cylindrical and has mutually parallel reference planes 241. The axis of the tube cap 200 is perpendicular to the reference plane 241, and the rotating part 110 is an open arc shape. In this embodiment, the rotating part 110 is a three-quarter arc shape, with the open section accounting for one-quarter of the arc, used to mate with the snap-fit ​​post 240. The two ends of the cylindrical snap-fit ​​post 240 are flattened to form reference planes 241 that are perpendicular to and parallel to the axis of the tube cap 200, making it easy to snap the snap-fit ​​post 240 into the open arc-shaped rotating part 110. It is only necessary to align the two ends of the open arc with the two reference planes 241 respectively, which facilitates the quick installation and removal of the baffle 100.

[0045] Example 3

[0046] This embodiment is the first embodiment of a pet feeder, including a housing 400, a cooking chamber 500 disposed in the housing 400 for heating food, a discharge tube support 300 communicating with the cooking chamber 500, a conveying component 600 disposed in the cooking chamber 500 for conveying food to the discharge port 210, and a discharge port cover assembly, which is snapped into the discharge tube support 300.

[0047] The pet feeder in this embodiment, such as Figure 7 , Figure 8 As shown, users only need to put pet food such as chilled canned food into the cooking chamber 500 for heating. The cooked food will fall into the conveying component 600, which will transport the food to the discharge port 210. During the movement of the food, it passes through the discharge pipe support 300, opens the discharge port cover component, and flows out from the discharge port 210 without manual operation.

[0048] like Figure 8 , Figure 9As shown, the conveying assembly 600 includes a motor 610 disposed within the housing 400, a conveying cylinder 620 communicating with the cooking chamber 500, a stirring rod 630 disposed within the cooking chamber 500 and connected to the motor 610, and a conveying screw 640 disposed within the conveying cylinder 620. The conveying cylinder 620 is disposed within the discharge pipe support 300. The conveying screw 640 is connected to the stirring rod 630, and the stirring rod 630 is provided with multiple sets of stirring blades 650. When the motor 610 drives the stirring rod 630 to rotate, the food is stirred and broken up by the stirring blades 650 in the cooking chamber 500. After the food falls into the conveying cylinder 620, the motor 610 drives the conveying screw 640 to rotate, gradually pushing the food out of the conveying cylinder 620, so that the food can push open the discharge port cover assembly, thereby realizing automatic opening of the cover.
