Description

Technical Field

[0001] This utility model relates to the technical field of grain storage bins, and in particular to a bin lid and a grain storage bin. Background Technology

[0002] Food storage bins are used to store food, such as cat or dog food. A food storage bin consists of a bin body for holding the food and a lid that seals the bin body. An air pump is installed inside the lid to evacuate air from the inside of the bin, creating a vacuum and preventing the food from oxidizing and spoiling. Currently, most bin lids have a manual vacuum-breaking button. This button is designed so that the vacuum-breaking hole on the lid is blocked upwards, and pressing the button downwards opens the vacuum hole, allowing outside air to enter the bin and release the vacuum. Only after the vacuum is released can the lid be opened. Currently, to improve the reliability of preventing food spoilage, the internal vacuum level is usually set too high. This means that users need to use considerable force to move the vacuum-breaking button downwards to open the vacuum hole, resulting in a poor user experience. Therefore, existing food storage bins need to be improved. Utility Model Content

[0003] This utility model provides a lid and a grain storage container for grain storage, mainly solving the technical problem of how to break the vacuum inside the grain storage container in a more labor-saving way.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A lid for a grain storage jar includes a shell, an air pump, and a vacuum breaking mechanism; the shell has a receiving cavity, the air pump and the vacuum breaking mechanism are both housed in the receiving cavity, and the bottom wall of the shell is provided with an air extraction hole and a vacuum breaking hole that are both connected to the receiving cavity, and the air pump is connected to the air extraction hole through an air pipe.

[0006] The vacuum breaking mechanism includes a button, a movable plate, and a flexible sealing element. The top surface of the housing is provided with a limiting hole, and the button is limited within the limiting hole. The movable plate is rotatably connected to the housing. The sealing element is fixed on the movable plate and located above the vacuum breaking hole. One end of the movable plate away from the sealing element extends downward toward the button. The bottom of the button has a pressing part that applies downward pressure to the movable plate. The bottom surface of the limiting hole has an avoidance hole corresponding to the pressing part that communicates with the receiving cavity.

[0007] In one of the technical solutions, the vacuum breaking mechanism further includes a first elastic member disposed between the movable plate and the inner wall of the housing. The first elastic member is disposed on the side of the movable plate facing away from the button, and the movable plate is subjected to the elastic force of the first elastic member, causing the sealing member to have a tendency to move closer to the vacuum breaking hole.

[0008] In one of the technical solutions, the vacuum breaking mechanism further includes a second elastic element disposed between the button and the inner wall of the housing, and the button has an upward tendency to move away from the limiting hole due to the elastic force of the second elastic element.

[0009] In one of the technical solutions, the bottom of the button is provided with multiple buckles, and the housing is provided with multiple slots on the side wall inside the limiting hole for the buckles to be snapped into one by one. The buckles can move up and down in the slots.

[0010] In one of the technical solutions, the bottom of the button has two protruding posts that bulge downwards. The two protruding posts are located on opposite sides of the pressing part, and each of the protruding posts is fitted with the second elastic element.

[0011] In one technical solution, the movable plate is provided with a mounting hole, and the sealing element includes a first connecting part, a second connecting part, and a third connecting part connected in sequence. The outer diameter of the first connecting part and the outer diameter of the third connecting part are both larger than those of the second connecting part. The sealing element is inserted into the mounting hole. The first connecting part is exposed downward relative to the bottom surface of the movable plate, and the third connecting part is exposed upward relative to the top surface of the movable plate. The end of the first connecting part or the end of the third connecting part is provided with a chamfered structure.

[0012] In one of the technical solutions, the housing includes an upper shell and a lower shell that are fixedly connected. The upper shell and the lower shell together form the accommodating cavity. The limiting hole is opened at the top of the upper shell, and the air extraction hole and the vacuum breaking hole are both opened at the bottom of the lower shell. The air pump is fixedly connected to the lower shell, and the movable plate is rotatably connected to the lower shell.

[0013] This application also provides a grain storage bucket, including a bucket body and a bucket lid as described in any of the above technical solutions. The bucket body is provided with an open grain storage trough, and the bucket lid is used to seal the opening of the grain storage trough. A sealing ring is provided between the bucket body and the bucket lid.

[0014] In one of the technical solutions, a Hall sensor is provided on one of the bucket lid and the bucket body, and a magnet is provided on the other. When the bucket lid is placed on the bucket body, the Hall sensor senses the magnet. The Hall sensor is communicatively connected to the air pump.

[0015] In one of the technical solutions, the bucket lid is detachably connected to the bucket body, a battery is provided in the accommodating cavity of the bucket lid, the battery provides power to the air pump, and a charging port electrically connected to the battery is provided on the shell of the bucket lid.

[0016] Compared with the prior art, the lid for grain storage bins provided by this utility model has at least the following beneficial effects:

[0017] This solution utilizes a vacuum pump to evacuate air from the evacuation port. During this process, the resulting negative pressure causes the seal fixed to the movable plate to reliably block the vacuum-breaking hole under external air pressure, creating a vacuum inside the grain storage container and preventing grain spoilage. When the grain needs to be used, simply press the button downwards. The button's pressing part pushes the movable plate to rotate, causing the seal fixed to the movable plate to move upwards away from the vacuum-breaking hole. This restores the internal air pressure of the grain storage container to atmospheric pressure, allowing the lid to be easily opened and the grain removed. This solution uses a rotating seal to achieve the vacuum-breaking function inside the grain storage container. The seal only needs to rotate a small angle to quickly open the vacuum-breaking hole, making it easier to achieve the vacuum-breaking function. Furthermore, the movable plate acts like a seesaw with a lever structure, using the lever to pry the seal away from the vacuum-breaking hole, significantly reducing the force required to drive the seal away. This allows for a more effortless vacuum-breaking function, thus optimizing the user experience. Attached Figure Description

[0032] It should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Please refer to the following: Figures 1 to 8 This utility model provides a grain storage bin, including a bin body 1 and a bin lid 2. The bin body 1 is provided with an open grain storage trough 11, into which a user can place grain. The bin lid 2 is used to seal the opening of the grain storage trough 11. In order to ensure the sealing between the bin body 1 and the bin lid 2, a sealing ring 3 is usually provided between the bin body 1 and the bin lid 2. The sealing ring 3 can be pre-fixed to the top of the bin lid 2, or it can be pre-fixed to the top of the bin body 1.

[0036] Please refer to the following: Figures 1 to 8 The lid 2 specifically includes a shell 21, a vacuum pump 22, and a vacuum breaking mechanism 23. The shell 21 has a receiving cavity 211, in which the vacuum pump 22 and the vacuum breaking mechanism 23 are both housed. The bottom wall of the shell 21 is provided with a vacuum hole 212 and a vacuum breaking hole 213, which are both connected upward to the receiving cavity 211. Moreover, when the lid 2 is closed relative to the barrel body 1, the vacuum hole 212 and the vacuum breaking hole 213 are actually connected downward to the grain storage tank 11. The vacuum pump 22 is connected to the vacuum hole 212 through an air pipe. The vacuum breaking mechanism 23 specifically includes a button 231, a movable plate 232, and a flexible sealing element 233. A limiting hole 214 is provided on the top surface of the housing 21, and the button 231 is limited within this limiting hole 214, so that the button 231 can only move up and down relative to the housing 21. The movable plate 232 is perpendicular to the housing 21. Figure 7The valve is rotated at point M. The seal 233 is fixed on the movable plate 232 and located above the vacuum hole 213. The seal 233 is used to seal the vacuum hole 213. The seal 233 is preferably a silicone part with good sealing performance. The end of the movable plate 232 away from the seal 233 extends downward toward the button 231. The bottom of the button 231 is provided with a pressing part 2311. The pressing part 2311 is used to apply downward pressure to the movable plate 232. The bottom surface of the limiting hole 214 is provided with a clearance hole 215 at the position corresponding to the pressing part 2311, which communicates with the accommodating cavity 211. The clearance hole 215 is used to avoid the pressing part 2311, so that the pressing part 2311 can apply downward pressure to the movable plate 232 below.

[0037] Specifically, in use, the grain storage bin of this solution uses a vacuum pump 22 to evacuate air from the evacuation port 212. During the evacuation process, a negative pressure is formed inside, which makes the seal 233 fixed on the movable plate 232 more reliably block the vacuum hole 213 under the pressure of the external air, so that the grain storage tank 11 inside the grain storage bin can form a vacuum state, thereby preventing the grain inside from spoiling. When the grain inside needs to be used, simply press the button 231 downwards. The pressing part 2311 of the button 231 will push the movable plate 232 to rotate, so that the seal 233 fixed on the movable plate 232 moves upwards away from the vacuum hole 213, thereby allowing the air pressure in the grain storage tank 11 inside the grain storage bin to return to the same as atmospheric pressure. At this time, the lid 2 can be easily opened and the grain inside can be taken out. This solution uses the rotation of the driving seal 233 to achieve the vacuum breaking function inside the grain storage tank. The seal 233 only needs to be rotated by a small angle to quickly open the vacuum breaking hole 213. This method makes it easier to achieve the vacuum breaking function. At the same time, the movable plate 232 is equivalent to a seesaw with a lever structure. Using the lever to pry the seal 233 away from the vacuum breaking hole 213 helps to significantly reduce the force required to drive the seal 233 away from the vacuum breaking hole 213. In other words, the vacuum breaking function inside the grain storage tank can be achieved in a more effortless way, thereby optimizing the user experience.

[0038] Please see Figure 4The vacuum breaking mechanism 23 also includes a first elastic element 24 disposed between the movable plate 232 and the inner wall of the housing 21. The first elastic element 24 is preferably a spring. This first elastic element 24 is disposed on the side of the movable plate 232 facing away from the button 231. Furthermore, the movable plate 232, under the elastic force of the first elastic element 24, has an upward rotational tendency, thereby causing the sealing element 233 to have a tendency to move closer to the vacuum breaking hole 213. By providing the first elastic element 24, the sealing element 233 can automatically abut against the vacuum breaking hole 213 when the button 231 is not pressed. When air is pumped out of the internal grain storage tank 11, the sealing element 233 can reliably block the vacuum breaking hole 213, thereby improving the reliability of forming a negative pressure inside the grain storage tank 11 when air is pumped out. In practice, when the button 231 is pressed down, the user needs to overcome the elastic force of the first elastic element 24.

[0039] Please refer to it again. Figure 4 The vacuum breaking mechanism 23 also includes a second elastic element 25 disposed between the button 231 and the inner wall of the housing 21. The second elastic element 25 is preferably a spring. The button 231, under the elastic force of the second elastic element 25, has an upward tendency to disengage from the limiting hole 214. By providing the second elastic element 25, when the vacuum inside the grain storage tank 11 is broken and the user releases the button 231, the button 231 can return to its initial position. Please refer to [further details omitted]. Figure 4 and Figure 8 Preferably, the bottom of the button 231 has two protruding posts 2313 protruding downwards. The two protruding posts 2313 are respectively located on opposite sides of the pressing part 2311. Each of the protruding posts 2313 is fitted with the aforementioned second elastic element 25. With this design, it can be ensured that the elastic direction of the second elastic element 25 is in the up and down direction, and the button 231 can be subjected to elastic force more evenly, preventing the button 231 from getting stuck in the limiting hole 214 and being unable to move up and down.

[0040] Please refer to the following: Figures 4 to 6 and Figure 8 The bottom of the button 231 is provided with multiple buckles 2312. The housing 21 has multiple slots 216 on the side wall inside the limiting hole 214. The multiple buckles 2312 are snapped into the multiple slots 216 one by one. The slots 216 are used to restrict the button 231 from moving upward away from the limiting hole 214 under the elastic force of the second elastic member 25. However, the buckles 2312 can move up and down in the slots 216, so that the button 231 can press down on the movable plate 232.

[0041] Please refer to the following: Figure 4 and Figure 9The movable plate 232 is provided with a mounting hole 2321. The sealing element 233 includes a first connecting part 2331, a second connecting part 2332, and a third connecting part 2333 connected in sequence. The first connecting part 2331, the second connecting part 2332, and the third connecting part 2333 are preferably cylindrical structures. The outer diameter of the first connecting part 2331 and the outer diameter of the third connecting part 2333 are larger than the outer diameter of the second connecting part 2332. The sealing element 233 is inserted into the mounting hole 2321 of the movable plate 232. After insertion, the first connecting part 2331 is exposed with its bottom surface facing downward relative to the movable plate 232, and the third connecting part 2333 is exposed with its top surface facing upward relative to the movable plate 232. This design helps to ensure that the sealing element 233 can be reliably fixed on the movable plate 232 and that the sealing element 233 can move upward away from the vacuum breaking hole 213 when the movable plate 232 is pried by the button 231, thereby improving the reliability of vacuum breaking. In addition, a chamfered structure 2334 is provided at the end of the first connecting part 2331 or the end of the third connecting part 2333. The chamfered structure 2334 makes it easier for the seal 233 to be inserted into the mounting hole 2321 of the movable plate 232.

[0042] Please refer to the following: Figures 1 to 7 The housing 21 is specifically designed to include an upper housing 217 and a lower housing 218 fixedly connected. The upper housing 217 and the lower housing 218 together enclose the aforementioned accommodating cavity 211. By designing the housing 21 as a separate unit, it is beneficial to install the vacuum pump 22 and the vacuum breaking mechanism 23 inside the housing 21. In fact, the aforementioned limiting hole 214 is opened at the top of the upper housing 217, and the aforementioned air extraction hole 212 and vacuum breaking hole 213 are both opened at the bottom of the lower housing 218. Preferably, the vacuum pump 22 is fixed at the top of the lower housing 218, and the movable plate 232 is preferably attached to the lower housing 218. Figure 7 Rotary connection at point M.

[0043] Please see Figure 5 One of the bucket lid 2 and the bucket body 1 is equipped with a Hall sensor 26, and the other is equipped with a magnet. The Hall sensor 26 is communicatively connected to the aforementioned air pump 22. In this embodiment, the Hall sensor 26 is preferably set on the bucket lid 2. When the bucket lid 2 is closed relative to the bucket body 1, the Hall sensor 26 can sense the magnet inside the bucket body 1. At this time, the air pump 22 can be automatically started to pump air from the inside of the grain storage tank 11. In addition, the user can also choose not to automatically start the air pump 22 after closing the bucket lid 2. The user can also start the air pump 22 by operating the control button 27 on the bucket lid 2 or by using a mobile APP.

[0044] Please refer to the following: Figure 1 and Figure 5The lid 2 and the body 1 are designed to be detachably connected. A rechargeable battery 28 is installed in the cavity 211 of the lid 2. This battery 28 is electrically connected to the air pump 22 to provide the power required for the air pump 22 to operate. The shell 21 of the lid 2 is provided with a charging port 29 that is electrically connected to the battery 28. When the battery 28 inside the lid 2 is depleted, the user can remove the lid 2 from the body 1 and then plug the charging cable into the charging port 29 of the lid 2 to charge the battery 28 inside the lid 2. Compared with the existing solution of designing a detachable battery module on the lid 2, this solution is less expensive while still achieving the function of recharging the lid 2.

[0045] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
