Description

Technical Field

[0001] This utility model relates to the field of pet feeding technology, and in particular to a rotary-sealed pet feeder. Background Technology

[0002] Pet feeders are primarily used to store pet food for regular feeding, making pet care convenient. Because the pet food in a feeder is dispensed periodically, it is stored for a relatively long time, thus requiring a high level of airtightness.

[0003] When a pet feeder dispenses food, it usually uses a rotating actuating mechanism to move the food from the collection bin to the dispensing port. After each dispensing, the dispensing port must be sealed; otherwise, the seal may be inadequate, resulting in the pet food inside becoming damp.

[0004] However, existing pet feeders generally have a sealing structure on the actuating component. This allows the actuating component to seal the outlet during rotation. However, friction between the actuating component and the internal structure of the sealing structure can affect the rotation of the actuating component, resulting in uneven rotation. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a rotary sealing pet feeder, in which a sealing element is sealed with a rotating pusher block at the outlet position, so that the rotation of the pusher block is smoother.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A rotary-sealed pet feeder, comprising,

[0008] A storage bucket, wherein the storage bucket has a storage cavity inside, and the storage bucket has an outlet that communicates with the storage cavity;

[0009] The discharge hopper assembly includes a discharge hopper and a sealing element. The discharge hopper is connected to the bottom end of the storage bucket and communicates with the outlet. The discharge hopper has a discharge port, and the sealing element seals and surrounds the periphery of the discharge port.

[0010] A feeding assembly includes a feeding component and a driving component. The feeding component is rotatably mounted on the discharge bin. The feeding component has a plurality of feeding blocks, which are distributed circumferentially around the feeding component. The driving component is used to drive the feeding component to rotate so that one of the feeding blocks corresponds to or is offset from the discharge port. When the feeding block corresponds to the discharge port, it is sealed with the sealing component.

[0011] Furthermore, the discharge port has a first discharge section and a second discharge section, the first discharge section extending axially along the discharge bin, the second discharge section extending radially along the discharge bin, and the first discharge section and the second discharge section communicating with each other.

[0012] The sealing element includes a first sealing section and a second sealing section. The first sealing section surrounds the outer periphery of the first outlet section. The second sealing section is connected to the bottom end of the first sealing section and surrounds the outer periphery of the second sealing section.

[0013] Furthermore, the sealing element also includes a sealing sleeve, which has a first through-hole and a second through-hole. The first through-hole corresponds to the first outlet section, and the second through-hole corresponds to the second outlet section. The sealing sleeve is fitted onto the outer peripheral wall of the discharge hopper. The first sealing section and the second sealing section surround the inner peripheral wall of the through-hole.

[0014] Furthermore, the top of the sealing sleeve is provided with a downwardly extending covering section, which extends downward through the top of the discharge hopper and covers the inner side of the top of the discharge hopper.

[0015] Furthermore, the discharge hopper is provided with a positioning protrusion; the sealing sleeve is provided with a positioning through hole; the positioning protrusion is used to pass through the positioning through hole.

[0016] Furthermore, both the first sealing section and the second sealing section are provided with sealing edges extending into the inside of the discharge port; the sealing edges are used to be deformed by the pressure of the pusher block.

[0017] Furthermore, both the outer periphery of the first outlet section and the outer periphery of the second outlet section are provided with a first buckle; both the first sealing section and the second sealing section are provided with a first latch; the first buckle is engaged with the first latch.

[0018] Furthermore, the first buckle is provided with a limiting piece; the limiting piece is used to press against the sealing element after the first buckle is engaged with the first bayonet.

[0019] Furthermore, the storage bin is equipped with a pusher, which includes a pusher shaft and several pusher blades. The pusher shaft is rotatably mounted on the storage bin. The pusher blades are used to push materials to the outlet when the pusher shaft rotates. The pusher shaft is used to be synchronously connected with the power shaft of the drive component.

[0020] Furthermore, the side wall of the outlet is provided with a scraper, which is used to scrape off the material of the pusher block when the pusher block rotates to the outlet position.

[0021] In summary, this utility model has the following technical effects:

[0022] 1. After each quantitative feeding is completed, the feeding block and the discharge port are sealed with a sealing element. After feeding is completed, the sealing element is used to seal the discharge port to prevent external moisture from entering through the discharge port and causing the material in the discharge hopper to become damp.

[0023] 2. Since the sealing element is located at the discharge port, it does not rotate with the pusher block of the pusher. It only cooperates to seal when the pusher block corresponds to the discharge port position. This will not affect the rotation of the pusher and the sealing state is stable.

Detailed Implementation

[0033] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] See Figures 1-8 This utility model discloses a rotary sealing pet feeder, including a storage bin 10, a dispensing chamber assembly and a pushing assembly. The storage bin 10 has a storage cavity 11 and an outlet 12, which communicates with the storage cavity. The storage cavity 11 can store pet food and other materials.

[0037] The specific dispensing hopper assembly includes a dispensing hopper 20 and a sealing element 40. The dispensing hopper 20 is connected to the bottom end of the storage container 10, and the dispensing hopper 20 is connected to the outlet 12, so that the pet food in the storage container 10 can be guided into the dispensing hopper 20 through the outlet 12. The dispensing hopper 20 is provided with a dispensing port 21, and the sealing element 40 is sealed around the periphery of the dispensing port 21.

[0038] In addition, the material pushing assembly includes a material pushing component and a driving component 50. The material pushing component is rotatably mounted on the discharge bin 20. The material pushing component is provided with a plurality of material pushing blocks 31, which are distributed circumferentially around the material pushing component. The driving component 50 can drive the material pushing component to rotate so that one of the material pushing blocks 31 corresponds to or is offset from the discharge port 21. When the material pushing block 31 corresponds to the discharge port 21, it is sealed with the sealing component 40.

[0039] Based on the above structure, when using the rotary sealing pet feeder of this utility model, pet food can be stored in the storage bin 10, and the discharge bin 20 can be assembled to the bottom of the storage bin 10 by screws or threads or by snap-fit, so that the outlet 12 of the storage bin 10 and the opening of the discharge bin 20 are connected. In this way, when feeding materials, the pet food in the storage bin 10 can be quantitatively fed into the discharge bin 20. Then, the drive component 50 drives the pusher component to rotate, which can drive the pusher block 31 on the pusher component to rotate. During the rotation, the pusher block 31 can push the material in the discharge bin 20 to the discharge port 21. The gap between two adjacent pusher blocks can allow the material to fall. In this way, each time the pusher component 30 rotates, it can push the material between the two pusher blocks to the discharge port 21, realizing quantitative feeding.

[0040] It should be noted that when the pusher 30 is not rotating, one of its push blocks is positioned at the discharge port 21 and seals with the seal 40. Each time the pusher 30 rotates, it can rotate the push block at the discharge port 21 to be offset from the discharge port 21, while the other push block faces the discharge port 21 and pushes the material out of the discharge port 21. When it is aligned with the discharge port 21 again, it seals with the seal 40. That is, after each quantitative push is completed, the pusher block 31 seals with the seal 40 at the discharge port 21. After the push is completed, the seal 40 seals the discharge port 21 to prevent external moisture from entering through the discharge port 21 and causing the material in the discharge hopper 20 to become damp.

[0041] Of course, if the sealing structure is set on the pusher block 31 of the pusher component, the seal 40 on the pusher block 31 will rub against the inner wall of the discharge chamber 20 during rotation. This will not only affect the rotation of the pusher block 31, but also cause wear on the seal 40, affecting the sealing effect in the later stage. Therefore, in this embodiment, since the seal 40 is set at the discharge port 21, it does not rotate with the pusher block 31 of the pusher component. It only cooperates to seal when the pusher block 31 corresponds to the position of the discharge port 21. This will not affect the rotation of the pusher component, and the sealing state is stable.

[0042] See Figure 1 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6This embodiment provides a first type of sealing element 40 structure. Specifically, the discharge port 21 has a first discharge section 211 and a second discharge section 212. The first discharge section 211 extends axially along the discharge chamber 20, and the second discharge section 212 extends radially along the discharge chamber 20. The first discharge section 211 and the second discharge section 212 are interconnected. Thus, when material is discharged, the pushing block can discharge the material from the axial first discharge section 211 and the radial second discharge section 212, thereby increasing the discharge speed.

[0043] The sealing element 40 includes a first sealing section 43 and a second sealing section 44. The first sealing section 43 is disposed around the outer periphery of the first outlet section 211. The second sealing section 44 is connected to the bottom end of the first sealing section 43 and is disposed around the outer periphery of the second sealing section 44. In this way, the first sealing section 43 seals the axial periphery of the first outlet section 211, and the second sealing section 44 seals the radial periphery of the second outlet section 212. The sealing is only performed at the discharge port 21, without having to cover the entire discharge hopper 20. This saves on the amount of sealing element 40 used and reduces costs.

[0044] Further, see Figure 2 , Figure 7 as well as Figure 8 This embodiment also provides a second sealing element 40 structure. In the second structure, the sealing element 40 further includes a sealing sleeve 46. The sealing sleeve 46 has a first through-hole and a second through-hole. The first through-hole corresponds to the first outlet section 211, and the second through-hole corresponds to the second outlet section 212. The sealing sleeve 46 is fitted onto the outer peripheral wall of the discharge hopper 20, and the first sealing section 43 and the second sealing section 44 surround the inner peripheral wall of the through-hole. That is, the first sealing section 43 surrounds the inner peripheral wall of the first through-hole, and the second sealing section 44 surrounds the inner peripheral wall of the second through-hole.

[0045] When the sealing element 40 is assembled with the discharge chamber 20, the sealing sleeve 46 of the sealing element 40 is fitted onto the outer periphery of the discharge chamber 20, fully covering the discharge chamber 20, thus providing a large sealing surface. After the sealing sleeve 46 is fitted, since the first sealing section 43 surrounds the inner peripheral wall of the first through-hole and the second sealing section 44 surrounds the inner peripheral wall of the second through-hole, the first sealing section 43 can correspondingly seal the periphery of the first outlet section 211, and the second sealing section 44 correspondingly seals the periphery of the second outlet section 212, thus providing a positioning seal at the discharge port 21 of the discharge chamber 20.

[0046] It should be noted that regardless of whether the seal 40 adopts the first or the second structure, the seal 40 can be made of materials such as sealing silicone or sealing rubber.

[0047] Furthermore, a downward-extending covering section can be provided at the top of the sealing sleeve 46. After the sealing sleeve 46 is fitted onto the outer peripheral wall of the discharge chamber 20, the covering section extends downward through the top of the discharge chamber 20 and covers the inner side of the top of the discharge chamber 20. This allows for sealing around the top edge of the discharge chamber 20. After the discharge chamber 20 is assembled with the storage bucket 10, the covering section at the top of the sealing sleeve 46 can seal the connection between the top of the discharge chamber 20 and the bottom of the storage bucket 10, further improving the internal sealing performance and providing better moisture protection.

[0048] Furthermore, since the sealing sleeve 46 and the discharge chamber 20 have a large sealing assembly surface, in order to prevent the sealing sleeve 46 from slipping off and to stabilize the assembly structure, a positioning protrusion 23 can be provided on the discharge chamber 20, and a positioning through hole 461 can be provided on the sealing sleeve 46. In this way, after the sealing sleeve 46 is assembled to the outside of the discharge chamber 20, the positioning protrusion 23 on the outside of the discharge chamber 20 passes through the positioning through hole 461 of the sealing sleeve 46 to achieve positioning assembly of the sealing sleeve 46, prevent it from falling off, and stabilize the sealing structure.

[0049] Regardless of whether the first or second sealing structure is used, in order to further improve the sealing effect, both the first sealing section 43 and the second sealing section 44 are provided with sealing edges 41. After the first sealing section 43 covers the first outlet section 211 and the second sealing section 44 covers the second outlet section 212, the sealing edges 41 can extend into the inside of the discharge port 21. In this way, when the pusher block 31 rotates to correspond with the discharge port 21, the pusher block 31 can press against the sealing edge 41, causing the sealing edge 41 to deform. After deformation, a larger sealing surface is generated to seal the position of the discharge port 21, thus improving the sealing effect.

[0050] Furthermore, to prevent stable assembly of the first sealing section 43 with the first outlet section 211 and the second sealing section 44 with the second outlet section 212, a first buckle 22 can be provided on the outer periphery of both the first outlet section 211 and the second outlet section 212; both the first sealing section 43 and the second sealing section 44 are provided with a first latch 45. When the sealing element 40 is assembled with the outlet 21 of the discharge chamber 20, the first sealing section 43 is correspondingly arranged around the periphery of the first outlet section 211, and the first latch 45 around the periphery of the first outlet section 211... The buckle 22 can be snapped into the first slot 45 of the first sealing section 43 for snapping, and the first buckle 22 around the second outlet section 212 can be snapped into the first slot 45 of the second sealing section 44 for snapping. This can effectively prevent the first sealing section 43 from separating from the second density section from the first outlet section 211 and the second outlet section 212. That is, it acts as a positioning element for the sealing element 40 at the outlet 21, and prevents separation at the outlet 21. The sealing structure at the outlet 21 is restricted, and the sealing structure is more stable.

[0051] Of course, in the absence of the first buckle 22 and the first latch 45, the assembly of the above-mentioned sealing element 40 with the discharge port 21 can also be achieved by using the elasticity of the sealant to achieve a tight fit at the discharge port 21 position, or by setting sealing grooves in the first sealing section 43 and the second sealing section 44, and covering the discharge port 21 position with the sealing groove structure.

[0052] Furthermore, a limiting piece 221 can be provided on the first buckle 22; after the first buckle 22 is engaged with the first latch 45, the limiting piece 221 is pressed against the seal 40, so that the limiting piece 221 is on the outside of the seal 40 to prevent detachment, and the assembly structure is more stable.

[0053] Furthermore, a pusher 60 is provided inside the storage bin 10. The pusher 60 includes a pusher shaft and several pusher blades 61. The pusher shaft is rotatably mounted on the storage bin 10, so that when the pusher shaft rotates, the pusher blades 61 can push the material to the outlet 12. The pusher shaft is used to synchronously connect with the power shaft of the drive unit 50. That is, when pushing the material, the drive unit 50 drives the pusher 30 and the pusher shaft of the pusher 60 to rotate simultaneously, so that the pusher blades 61 in the storage bin 10 push the material to the outlet 12 position and drop it into the gap between the two pusher blocks. At the same time, the pusher blocks rotate and push the material out through the discharge port 21 position.

[0054] Of course, the aforementioned driving component can be a drive motor as used in existing technology, whose shaft can drive the pusher and pusher components to rotate. Alternatively, the drive motor's shaft can be combined with a gear transmission structure to drive the pusher and pusher components to rotate. The specific structure of the driving component can be selected according to actual needs.

[0055] Furthermore, the side wall of the outlet 12 is provided with a scraper. The scraper can scrape off the material on the pusher block 31 when the pusher block 31 rotates to the outlet 12 position, so as to prevent the material from sticking to the pusher block 31 and causing jamming. The scraper can be a structure such as a brush.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
