Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a food storage bin and feeder. Background Technology

[0002] Most existing feeder containers use a structure consisting of a container body and a lid. To improve sealing, a common practice is to install a sealing ring on the lid. When the lid is closed, the sealing ring comes into close contact with the inner wall of the container, filling the gaps to achieve a seal.

[0003] However, of the two structures mentioned above, the grain storage hopper without a sealing ring is easier to open and close, but its sealing performance is insufficient, making the grain susceptible to moisture and spoilage. While the grain storage hopper with a sealing ring improves sealing, frictional resistance between the sealing ring and the inner wall of the hopper causes stumbling and difficulty in operation, resulting in a poor user experience. Therefore, there is an urgent need to design a grain storage hopper that balances high sealing performance with smooth operation. Utility Model Content

[0004] This utility model provides a grain storage bin and a feeder to achieve both high sealing performance and smooth operation.

[0005] In a first aspect, this utility model discloses a grain storage bin, comprising:

[0006] The barrel has an opening at the top that communicates with its interior;

[0007] A top cover, which is provided at the opening;

[0008] A force-applying component is movably connected to the upper cover. The force-applying component includes a force-applying part and a connecting part. The force-applying part is located on the outside, and the connecting part is connected to the force-applying part and located inside the barrel.

[0009] An elastic seal is located inside the barrel and connected to the connecting part. The elastic seal is spaced apart from the top cover. The elastic seal includes an annular sealing part that surrounds the inner wall of the barrel.

[0010] When the force-applying component moves the elastic seal to abut against the top cover, the annular sealing part can deform under force and expand outward to abut against the inner wall of the barrel.

[0011] In one embodiment, the upper cover is provided with a sliding groove that extends in the depth direction of the barrel, and the upper cover is also provided with an opening communicating with the sliding groove.

[0012] The force-applying component also includes a sliding part, which is slidably connected to the slide groove and connected to the connecting part. In the extension direction perpendicular to the slide groove, the force-applying part is rotatably connected to the sliding part through the through-hole. Rotating the force-applying part allows the sliding part to slide in the slide groove, and the elastic seal can contact or separate from the top cover.

[0013] In one embodiment, the force-applying part includes a first end and a second end, and the sliding part is configured as two symmetrically arranged connecting lugs; two openings are provided, and the two openings are symmetrically arranged on both sides of the upper cover, so that the two connecting lugs are rotatably connected to the first end and the second end respectively.

[0014] In one embodiment, the top of the cover is provided with a limiting notch, and the force-applying part of the force-applying member can be screwed into or out of the limiting notch. The limiting notch is used to limit the rotation range of the force-applying part.

[0015] In one embodiment, the first end includes a first bottom wall and a first side wall adjacent to the first bottom wall. The distance between the first bottom wall and the rotation axis of the first end is greater than the distance between the first side wall and the rotation axis of the first end, so that when the first end rotates to the point where the first bottom wall abuts against the bottom of the limiting notch and the connecting segment is located in the limiting notch, the elastic seal can contact the top cover; and when the first end rotates to the point where the first side wall abuts against the bottom of the limiting notch and the connecting segment is rotated out of the limiting notch, the elastic seal can separate from the top cover.

[0016] In one embodiment, the annular sealing portion is hollow inside to define an elastic compression space, and the annular sealing portion has a gradually narrowing tendency in the direction away from the upper cover.

[0017] In one embodiment, the connecting part includes an outer peripheral surface surrounding the inner wall of the grain bucket, and an annular groove is provided on the outer peripheral surface; the elastic seal also includes a fixing part, which is connected to the side of the annular seal away from the top cover, and the fixing part is provided with a connection port communicating with the interior of the annular seal; the fixing part also includes an end wall adjacent to the connection port, and the end wall is clamped at the annular groove.

[0018] Secondly, this utility model also discloses a feeder, which includes the grain storage bucket described in the above embodiments.

[0019] In one embodiment, the system further includes a base and a water storage tank. The outer periphery of the base is provided with a food outlet and a water outlet. The food outlet is used to supply food to the feeding trough, and the water outlet is used to add water to the drinking trough. The food storage tank is detachably connected to the base and communicates with the food outlet, allowing the food in the food storage tank to be discharged from the food outlet. The water storage tank is detachably connected to the base and is located adjacent to the food storage tank, communicating with the water outlet, allowing the water in the water storage tank to flow out from the water outlet.

[0020] In one embodiment, a control panel is detachably connected to the outer peripheral surface of the base, and a main control board is provided inside the base, the main control board being electrically connected to the control panel.

[0021] The beneficial effects of the pet water and feeder provided in this embodiment of the utility model are as follows: the food storage container can not only significantly improve the sealing effect, but also make the opening and closing of the lid smoother, thereby greatly improving the user experience.

[0022] Specifically, the top cover covers the container. By operating the force-applying part of the force-applying component, the connecting part moves, causing the elastic seal to move and come into contact with the top cover. The annular sealing part of the elastic seal, under the pressure of the top cover, deforms and gradually expands outward until it tightly adheres to the inner wall of the container, thus improving the sealing of the grain storage container and effectively preventing the grain from becoming damp and spoiling. Furthermore, by operating the force-applying part in the opposite direction, the connecting part can cause the elastic seal to disengage from the top cover. At this point, the annular seal, no longer under pressure, recovers its shape through its own elasticity, releasing its contact with the inner wall of the grain container. Throughout the process of opening or closing the top cover, the frictional resistance between the elastic seal and the inner wall of the container is reduced, making operation easier and smoother, and providing a better user experience.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] This utility model embodiment provides a grain storage bin 10, which is applied to a feeder 1000, such as... Figure 1 - Figure 2 As shown, the grain storage bin 10 includes a bin body 11, a top cover 12, a force-applying component 13, and an elastic sealing component 14. The top of the bin body 11 has an opening 111 communicating with its interior; the top cover 12 is placed over the opening 111; the force-applying component 13 is movably connected to the top cover 12, and includes a force-applying part 131 and a connecting part 132. The force-applying part 131 is located externally, and the connecting part 132 is connected to the force-applying part 131 and located inside the bin body 11; the elastic sealing component 14 is located inside the bin body 11 and connected to the connecting part 132. The elastic sealing component 14 is spaced apart from the top cover 12, and includes an annular sealing part 141 surrounding the inner wall of the bin. When the force-applying component 13 moves the elastic sealing component 14 to abut against the top cover 12, the annular sealing part 141 deforms under force and expands outward to abut against the inner wall of the bin body. This application solves the problems of insufficient sealing performance and jamming caused by friction of the sealing component when opening and closing the cover in the prior art. The grain storage bin 10 not only significantly improves the sealing effect, but also makes the opening and closing of the lid 12 smoother, thereby greatly improving the user experience.

[0042] Specifically, the top cover 12 covers the barrel 11. By operating the force-applying part 131 of the force-applying component 13, the force-applying part 131 drives the connecting part 132 to move, thereby moving the elastic seal 14 to abut against the top cover 12. The annular sealing part 141 of the elastic seal 14 deforms and gradually expands outward due to the pressure from the top cover 12 until it fits tightly against the inner wall of the barrel 11, thereby improving the sealing performance of the grain storage barrel 10 and effectively preventing the grain from getting damp and deteriorating. Furthermore, by operating the force-applying part 131 in the opposite direction, the connecting part 132 can also cause the elastic seal 14 to disengage from the top cover 12. At this time, since the annular sealing part 141 is released from the force, it recovers through its own elasticity and is no longer abutting against the inner wall of the grain barrel. During the entire process of the user opening or closing the top cover 12, the frictional resistance between the elastic seal 14 and the inner wall of the barrel 11 is smaller, the operation becomes easier and smoother, and the user experience is better.

[0043] It should be noted that the elastic seal 14, due to its elastic deformation characteristics, can deform under stress and return to its initial state using its own elastic potential energy when not under stress. The elastic seal 14 can be made of silicone, rubber, or other elastic materials, and there is no limitation on its materials.

[0044] There are many ways in which the force-applying component 13 is movably connected to the upper cover 12, and no limitation is made here. Exemplarily, in one embodiment, the force-applying component 13 further includes a screw portion (not shown in the figure), which is threadedly connected to the upper cover 12. The screw portion is located between the force-applying portion 131 and the connecting portion 132. By turning the force-applying portion 131, the connecting portion 132 is moved up or down, thereby allowing the elastic seal 14 to contact or separate from the upper cover 12. In another embodiment, the force-applying component 13 further includes a rack portion (not shown in the figure). A gear is rotatably provided inside the upper cover 12, and the gear is meshed with the rack. The rack portion is located between the force-applying portion 131 and the connecting portion 132. By pushing or pulling the force-applying portion 131, the connecting portion 132 is moved up or down, thereby allowing the elastic seal 14 to contact or separate from the upper cover 12.

[0045] Reference Figure 3 - Figure 6 Preferably, in another embodiment, the upper cover 12 is provided with a groove 121 extending in the depth direction of the barrel 11, and the upper cover 12 is also provided with an opening 122 communicating with the groove 121; the force-applying member 13 also includes a sliding part 133, which is slidably connected to the groove 121 and connected to the connecting part 132. In the extension direction perpendicular to the groove 121, the force-applying part 131 is rotatably connected to the sliding part 133 through the opening 122. Rotating the force-applying part 131 causes the sliding part 133 to slide in the groove 121, and the elastic seal 14 can contact or separate from the upper cover 12. In this way, the user only needs to operate within a limited angle (such as... Figure 5 and Figure 6 (As shown in O) Rotate the force-applying part 131, and the rotational motion of the force-applying part 131 can be converted into the sliding part 133 moving vertically in the groove 121 (as shown in O). Figure 5 and Figure 6 The elastic seal 14 moves up or down along the Z-axis (i.e., the depth direction of the barrel 11) to bring it into contact with or separate from the top cover 12. This operation method is more intuitive, convenient, and efficient, and effectively saves time in sealing and unsealing operations.

[0046] Specifically, the force-applying part 131 includes a first end 1311 and a second end 1312, and the sliding part 133 is configured as two symmetrically arranged connecting lugs 1331; two openings 122 are provided, and the two openings 122 are symmetrically arranged on both sides of the upper cover 12, so that the two connecting lugs 1331 are rotatably connected to the first end 1311 and the second end 1312 respectively. In this way, the two connecting lugs 1331 are rotatably connected to the first end 1311 and the second end 1312 respectively, which can improve the rotational connection stability between the force-applying part 131 and the sliding part 133, and is more conducive to the force transmission to the connecting part 132, so as to ensure that the elastic seal 14 can contact or separate from the upper cover 12, thereby improving the reliability of the overall structure.

[0047] In one embodiment, the force-applying part 131 further includes a connecting section 1313. The first end 1311 is connected to the second end 1312 through the connecting section 1313. The top of the upper cover 12 is provided with a limiting notch 123. The first end 1311 and the second end 1312 are located in the limiting notch 123, and the limiting notch 123 is located on the rotation path of the force-applying part 131, so that the connecting section 1313 can be screwed into or out of the limiting notch 123. The limiting notch 123 is used to limit the rotation range of the force-applying part 131. With this configuration, the limiting notch 123 can limit the rotation range of the force-applying part 131, which helps to improve the accuracy of the user's operation of the force-applying part 131 and reduce the occurrence of misoperation.

[0048] In addition, after the connecting section 1313 is rotated out of the limiting notch 123, the connecting section 1313 can also serve as a handle for the user to hold, making it easier for the user to open and close the top cover 12.

[0049] In one embodiment, the first end 1311 includes a first bottom wall 1311a and a first side wall 1311b adjacent to the first bottom wall 1311a. The distance between the first bottom wall 1311a and the rotation axis of the first end 1311 is greater than the distance between the first side wall 1311b and the rotation axis of the first end 1311. This allows the elastic seal 14 to contact the upper cover 12 when the first end 1311 rotates to the point where the first bottom wall 1311a abuts against the bottom of the limiting notch 123 and the connecting segment 1313 is located in the limiting notch 123. Furthermore, when the first end 1311 rotates to the point where the first side wall 1311b abuts against the bottom of the limiting notch 123 and the connecting segment 1313 is rotated out of the limiting notch 123, the elastic seal 14 can separate from the upper cover 12. With this configuration, when the connecting section 1313 is screwed into the limiting notch 123, the first bottom wall 1311a abuts against the bottom of the limiting notch 123, at which point the elastic seal 14 contacts the upper cover 12 to seal the grain hopper. The distance between the first bottom wall 1311a and the rotation axis of the first end 1311 (e.g., ...) Figure 6 (as shown in p) is greater than the distance between the first sidewall 1311b and the axis of rotation of the first end 1311 (e.g., p). Figure 5 As shown in u), when the connecting section 1313 is rotated out of the limiting notch 123 until the first sidewall 1311b abuts against the bottom of the limiting notch 123, the rotation axis of the first end 1311 will descend relative to the slide groove 121, thereby causing the connecting part 132 to move downward and the elastic seal 14 to separate from the upper cover 12.

[0050] Similarly, the second end 1312 includes a second bottom wall and a second side wall adjacent to the second bottom wall, the distance between the second bottom wall and the axis of rotation of the second end 1312 being greater than the distance between the second side wall and the axis of rotation of the second end 1312.

[0051] It is worth mentioning that, by implementing the above embodiments, when the user needs to unseal the grain storage bin 10, they only need to unscrew the connecting section 1313 out of the limiting notch 123. At this time, the elastic sealing element 14 can release the seal, and the user can then lift the top cover 12 by holding the connecting section 1313 to complete the opening action. When the user needs to close the cover, they only need to fasten the top cover 12 and then screw the connecting section 1313 into the limiting notch 123. At this time, the elastic sealing element 14 can seal the bin body 11. The smoothness of the entire operation process is greatly improved, and the user experience is better.

[0052] In addition, when the grain storage bin 10 is closed and sealed, the entire force-applying part 131 is completely contained in the limiting notch 123, which can reduce the space occupied by the force-applying part 131 and reduce the size of the grain storage bin 10 itself.

[0053] In one embodiment, a support 1314 is provided outside the force-applying part 131, and the support 1314 is located on the rotation path of the force-applying part 131. With this arrangement, the user can apply force to the force-applying part 131 through the support 1314, making it easier for the user to operate the force-applying part 13.

[0054] In one embodiment, a boss is provided on the side of the top cover facing the opening. The boss is received at the opening, and the outer contour shape of the boss matches the inner contour shape of the opening. The resilient seal is located on the side of the boss away from the force-applying element. In this way, the boss can mate with the opening to guide the top cover to be placed on the barrel body in the correct installation direction.

[0055] Reference Figure 4 and Figure 7 In one embodiment, the annular sealing portion 141 is hollow inside to define an elastic compression space 1411, and the annular sealing portion 141 gradually narrows in the direction away from the upper cover 12. This configuration provides a sufficient buffer area in the elastic compression space 141 when the side of the annular sealing portion 141 closest to the upper cover 12 comes into contact with it, allowing the annular sealing portion 141 to deform more smoothly and fully. Furthermore, because the annular sealing portion 141 has a gradually narrowing profile from top to bottom, it effectively guides the deformation direction of the annular sealing portion 141 when compressed, allowing it to deform and expand stably from the center outwards. This makes it easier and more reliable for the annular sealing portion 141 to deform and press against the inner wall of the barrel 11, achieving an excellent sealing effect.

[0056] Reference Figure 4In one embodiment, the connecting portion 132 includes an outer peripheral surface 1321 surrounding the inner wall of the grain hopper, and an annular groove 1321a is provided at the outer peripheral surface 1321. The elastic seal 14 also includes a fixing portion 142, which is connected to the side of the annular seal 141 away from the upper cover 12. The fixing portion 142 has a connection port 1421 communicating with the interior of the annular seal 141. The fixing portion 142 also includes an end wall 1422 adjacent to the connection port 1421, which is clamped at the annular groove 1321a. With this arrangement, the end wall 1422 and the annular groove 1321a cooperate to increase the contact area between the elastic seal 14 and the connecting portion 132, which is more conducive to improving the connection stability of the two and further improving the reliability of the overall structure.

[0057] Reference Figure 8 and Figure 9 The present invention also discloses a feeder 1000, which includes the grain storage bucket 10 of the above embodiments.

[0058] In one embodiment, the feeder 1000 further includes a base 20 and a water storage tank 30; the outer peripheral surface 1321 of the base 20 is provided with a food outlet 22 and a water outlet, the food outlet 22 is used to supply food to the feeding bowl 40, and the water outlet is used to add water to the drinking bowl 50; the food storage tank 10 is detachably connected to the base 20 to communicate with the food outlet 22, and the food in the food storage tank 10 can be discharged from the food outlet 22; the water storage tank 30 is detachably connected to the base 20 and is adjacent to the food storage tank 10 to communicate with the water outlet, and the water in the water storage tank 30 can flow out from the water outlet. With this configuration, both the food storage bin 10 and the water storage bin 30 are mounted on the same base 20. Food from the food storage bin 10 can be supplied to the feeding bowl 40 through the food outlet 22 of the base 20, while water from the water storage bin 30 can be supplied to the water bowl 50 through the water outlet of the base 20. The integration of the food and water bins on the same base 20 significantly reduces the overall space occupied by the equipment. Users only need to operate one device to simultaneously supply food to the pet's feeding bowl 40 and refill water to the water bowl 50, greatly improving ease of use and reducing daily maintenance workload.

[0059] There are many ways to detach the water tank 30, the grain tank 10 and the base 20, such as magnetic connection or plug connection, and no limit is made on the connection method here.

[0060] In one embodiment, a control panel 21 is detachably connected to the outer peripheral surface 1321 of the base 20, and a main control board (not shown in the figure) is provided inside the base 20, which is electrically connected to the control panel 21. In this way, the control panel 21 facilitates user operation of the feeder 1000, and the feeder 1000 can also replace different types of control panels 21 according to different functions, giving users more diverse choices.

[0061] There are many ways to detachably connect the control panel 21 and the base 20. For example, they can be connected by magnetic attraction or snap-fit, and no limitation is made here.

[0062] Specifically, the control components include a display screen (not shown in the figure), a microphone (not shown in the figure), a camera component, and several buttons; the display screen, microphone, buttons, and camera component are all electrically connected to the main control board. The display screen can display information, the microphone is used to play sound, and the buttons facilitate user control of the feeder 1000, thereby achieving better human-computer interaction.

[0063] In one embodiment, the main control board includes a communication module, a video processing module, a food dispensing control module, a pet sensing module, and a recording module. The communication module allows users to remotely connect to and operate the pet water and feeder 1000 more stably via a mobile terminal, and to remotely communicate with their pets. The video processing module processes captured video information, ensuring stable compression and storage of the input video source. The food dispensing control module controls the number of times food is dispensed at regular intervals. The pet sensing module determines whether the pet is near the device based on the image captured by the camera component. The recording module records and plays user-recorded audio to attract the pet. This configuration makes the feeder 1000 more functional and further improves the user experience.

[0064] Ideally, the main control board also includes a pet behavior analysis module to determine the pet's current status, allowing users to better understand the pet's situation at home.

[0065] In one embodiment, the pet water feeder also includes a power supply module (not shown in the figure). The power supply module is installed at the base 20 and is electrically connected to the main control board. The power supply module includes a DC power supply and an AC power supply. The AC power supply is electrically connected to a household socket via a power cord to power the main control board; the DC power supply powers the main control board via a battery pack. Thus, the pet water feeder can be powered by both a plug and a battery pack, providing dual power supply protection. In the event of a power outage, it can automatically switch to battery power to ensure continuous operation of the device and prevent interruption of pet feeding.

[0066] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
