Description
A pet feeder with good sealing performance Technical Field
[0001] This invention relates to the technical field of pet feeding, and in particular to the technical field of pet feeders with good sealing performance. Background Technology
[0002] With the improvement of living standards, more and more families in modern society are keeping pets. Modern life is very fast-paced, and many people cannot feed their pets during work or leisure time when they are out. Most people will put food in a bowl before leaving and let their pets eat on their own, searching for food when they want to. However, this can easily lead to pets overeating and not eating regularly, causing indigestion and harming their health, bringing unnecessary trouble to the owner. Therefore, pet feeders, as an important part of a pet's basic needs, have gradually become popular among pet owners.
[0003] Pet feeders typically allow for timed and measured feeding of pets, providing convenience for pet owners. For example, Chinese invention patent CN104067953A discloses a pet feeder mainly composed of a base shell, a feeding hopper, a food tray, a motor, and a power switch. The base shell has a feeding port inside, below which is a spiral sleeve fixedly connected to the feeding port. A screw is installed inside the spiral sleeve, one end of which is fixedly connected to the motor, and the other end is fixed inside the spiral sleeve via a screw support. The screw has spiral blades. A nose cap is installed on the outside of the spiral sleeve and fixedly connected to the base shell by a snap-fit. The nose cap has a downward-curving feeding channel inside. The base shell has a base with a groove at its bottom. A food tray is located below the nose cap and is positioned within the groove of the base. The pet feeder also includes a circuit control system for controlling various feeding functions. This pet feeder uses a rotating spiral blade to deliver food from the feed hopper to the food dish for the pet. However, the problem with this type of feeder is that the spiral blade cannot be sealed, leaving the pet food inside the feed hopper directly exposed to the air. External air and moisture can easily enter the feed hopper, affecting the pet food and causing it to spoil. Summary of the Invention

[0035] Referring to Figures 1-9, the present invention discloses a pet feeder with good sealing performance, comprising a main body 1, a basin 2 for holding pet food on one side of the main body 1, a food storage bin 3 with its opening facing downwards inside the main body 1, a rotating dispensing mechanism at the opening of the food storage bin 3, the rotating dispensing mechanism including a third cover 6 located at the opening of the food storage bin 3 and a first cover 4 located between the third cover 6 and the opening of the food storage bin 3, a second cover 5 and a rotating space 11 for the second cover 5 to rotate are provided between the first cover 4 and the third cover 6, the second cover 5 being rotatably disposed in the rotating space. Inside compartment 11, the first cover 4 is provided with a first discharge port 41 that communicates with the grain storage space inside the grain storage jar 3. The second cover 5 is provided with two second grain storage parts 51 that correspond to the first discharge port 41. The second grain storage parts 51 are arranged through the upper and lower surfaces of the second cover 5. The third cover 6 is provided with a third discharge port 61 that corresponds to the second grain storage parts 51. The third discharge port 61 and the first discharge port 41 are arranged alternately. The main body 1 is also provided with a grain discharge channel 12. One end of the grain discharge channel 12 is connected to the third discharge port 61, and the other end is set towards the basin 2. In this embodiment, a food storage bin 3 is used to store pet food, preventing it from getting damp and spoiling. A basin 2 is provided to receive the pet food and feed it to the pet. The food storage bin 3 is sealed by the cooperation of three layers of lids: a first lid 4, a second lid 5, and a third lid 6. This reduces the interaction between the inside of the food storage bin 3 and the outside air during the dispensing process, preventing the pet food stored inside from getting damp or spoiling. Quantitative dispensing can be completed by controlling the rotation of the second lid 5, making the dispensing amount more controllable. During dispensing, the second lid 5 is rotated. When the upper end of the second food storage section 51 of the second lid 5 is connected to the first discharge port 41, the pet food stored in the food storage bin 3 can fall into the second food storage section 51 through the first discharge port 41. At this time, the second food storage section 51 is offset from the third discharge port 61, and the second lid 5 can fit against the upper surface of the third lid 6, preventing air from entering. The second cover 5 continues to rotate, and the second food storage section 51 is offset from the first feeding port 41. At this time, the upper end of the second food storage section 51 is closed until the second cover 5 rotates to the point where the second food storage section 51 is connected to the third feeding port 61. The pet food stored in the second food storage section 51 can be discharged through the third feeding port 61. At this time, the upper surface of the second cover 5 can fit against the first cover 4, thus keeping it sealed and preventing air from entering the food storage space through the second food storage section 51 and the first feeding port 41. This also minimizes the interaction between the food storage bin 3 and the outside air during the discharge process, preventing external moisture, bacteria, fungi, and dust from entering the food storage bin 3. The pet food discharged from the third feeding port 61 flows into the basin 2 through the food discharge channel 12 for the pet to eat. The food discharge channel 12 is inclined so that it has a certain angle, and the pet food can automatically roll into the basin 2 under the action of gravity.
[0036] Referring to Figures 1, 2, and 3, a feeding section 15 for placing the basin 2 is provided on one side of the main body 1. The feeding section 15 is detachably mounted on its upper side, and a weighing sensor 16 is provided on the feeding section 15 for cooperating with the basin 2. The weighing sensor 16 is connected to the control system inside the main body 1. By monitoring the weight of pet food in the basin 2, the amount of food consumed can be monitored. The weighing sensor 16 can also be used to control the automatic replenishment of pet food. When the weight of pet food in the basin 2 is lower than a certain value, the rotating dispensing mechanism can be controlled to automatically operate and replenish the pet food.
[0037] Referring to Figures 1 and 3, the bowl 2 is gradually tilted downwards from the direction closest to the main body 1 to the direction furthest from the main body 1. This facilitates the automatic collection of pet food away from the main body 1 under the influence of gravity, reducing the impact of the main body 1 on the pet's eating process. Example
[0038] Referring to Figures 1 and 3, the main body 1 has an installation cavity 13 for housing the food storage bin 3 and the rotary dispensing mechanism. The food storage bin 3 is detachably installed in the installation cavity 13, and the top of the installation cavity 13 is provided with a cover plate 14 detachably connected to it. The detachable installation of the food storage bin 3 inside the main body 1 allows for easy removal and replacement of pet food, making pet food replacement more convenient. In this embodiment, when the food storage bin 3 is full of pet food, it and the rotary dispensing mechanism can be sold as a whole. Replacing the food storage bin 3 and the rotary dispensing mechanism as a whole during replacement makes pet food replacement more convenient, changing the pet food replacement method and eliminating the need for cumbersome steps such as opening bags and emptying food.
[0039] Referring to Figures 4, 5, and 6, a vertically positioned drive shaft 52 is provided at the end of the second cover 5 furthest from the grain storage hopper 3. A through hole 62 adapted to the drive shaft 52 is provided on the third cover 6. The drive shaft 52 is rotatably connected to the through hole 62. A drive motor (not shown in the figures) is provided inside the main body 1 and is drively connected to the drive shaft 52. A transmission slot 521 and a transmission block are respectively provided at the end of the drive shaft 52 and the drive shaft of the drive motor, and the transmission slot 521 and the transmission block are detachably connected. This facilitates the replacement of the grain storage hopper 3 and the rotating discharge mechanism as a whole, and facilitates transmission.
[0040] Preferably, a sealing ring 9 is provided between the drive shaft 52 and the inner wall of the through hole 62. The sealing ring 9 is used to improve the sealing between the drive shaft 52 and the inner wall of the through hole 62, preventing outside air from entering the interior through the through hole 62.
[0041] Referring to Figures 4, 5, 6, and 7, a stirring blade 7 is provided on the side of the first cover 4 near the internal storage space of the food storage bin 3. A vertically arranged blade shaft 71 is provided in the middle of the stirring blade 7. The blade shaft 71 passes through the first cover 4 and is fixedly connected to the second cover 5. The blade shaft 71 is rotatably connected to the first cover 4. When the second cover 5 rotates, it can drive the stirring blade 7 to rotate as well, thereby agitating the pet food inside and facilitating its flow into the first feeding port 41, preventing the pet food from clumping.
[0042] Referring to Figures 6 and 9, the third cover 6 is detachably fixed to the grain storage jar 3. The opening of the grain storage jar 3 has a first stepped surface 32 that matches the outer ring of the first cover 4. The third cover 6 has a second stepped surface 63 that matches the outer ring of the first cover 4. The first cover 4 is located between the second stepped surface 63 and the first stepped surface 32. When the third cover 6 is threadedly connected to the grain storage jar 3, the second stepped surface 23 of the third cover 6 can press the first cover 4 onto the first stepped surface 32, thereby firmly fixing the first cover 4 and improving the sealing between the outer ring of the first cover 4 and the grain storage jar 3, preventing outside air from entering through the gap between the first cover 4 and the grain storage jar 3. (Example)
[0043] Referring to Figures 10 and 11, an elastic element 8 is provided between the second cover 5 and the third cover 6 to drive the second cover 5 to translate towards the first cover 4. The elastic element 8 drives the second cover 5 to move towards the end of the first cover 4, so that the second cover 5 can fit against the first cover 4, improving the sealing between the second cover 4 and the first cover 4. When the first discharge port 41 is misaligned with the second grain storage section 51, the mutually fitted second cover 5 and first cover 4 can prevent air from entering the interior of the barrel 1 through the gap between the second cover 5 and the first cover 4.
[0044] Preferably, the elastic element 8 is a spring, and the second cover 5 is provided with a spring cavity 54 for accommodating the spring. The spring cavity 54 is annular, which makes the spring more stable and reduces costs.
[0045] Referring to Figures 10 and 12, the second cover 5 has a sealing protrusion 55 at one end away from the elastic member 8, which is adapted to the first discharge port 41. The sealing protrusion 55 can cooperate with the first discharge port 41 to seal the first discharge port 41, improve the sealing performance, and prevent air from entering.
[0046] Preferably, the second cover 5 is covered with a silicone layer. The interior of the second cover 5 is rigid and serves as a support, while the silicone layer has a certain degree of elasticity, allowing it to better fit with the third cover 4 and the first cover 6, thereby improving the sealing performance.
[0047] Working process of this invention:
[0048] This invention discloses a pet feeder with good sealing performance. During operation, when dispensing food, the second cover 5 is controlled to rotate. When the upper end of the second food storage section 51 of the second cover 5 is connected to the first dispensing port 41, the pet food stored in the food storage bin 3 can fall into the second food storage section 51 through the first dispensing port 41. At this time, the second food storage section 51 is offset from the third dispensing port 61, and the second cover 5 can fit against the upper surface of the third cover 61 to prevent air from entering. The second cover 5 continues to rotate, and the second food storage section 51 and the first dispensing port 41... The feed inlets 41 are staggered, and the upper part of the second food storage section 51 is closed until the second cover 5 rotates to connect the second food storage section 51 with the third feed inlet 61. The pet food stored in the second food storage section 51 can be discharged through the third feed inlet 61. At this time, the upper surface of the second cover 5 can fit with the first cover 4 to keep it closed and prevent air from entering the food storage space through the second food storage section 51 and the first feed inlet 41. The pet food discharged from the third feed inlet 61 flows into the basin 2 through the food outlet channel 12 for the pet to eat.
