Description

Technical Field

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

[0002] To improve sealing performance and prevent grain from getting damp and spoiling, existing grain storage containers are often designed with a vacuum structure. This means that the air inside the container is extracted by an air extraction device to create a negative pressure environment, thereby inhibiting bacterial growth and delaying grain oxidation and spoilage. However, in actual use, if users need to open such vacuum grain storage containers, the negative pressure inside often makes it difficult to open the lid. This is not only inconvenient to use, but may also cause damage to the lid or spillage of contents due to excessive force.

[0003] Currently, some vacuum grain storage containers use a manual micro-vent valve for depressurization, which has problems such as complex structure, inconvenient operation, and insufficient sealing. Users often need to unscrew the small nut or pull out the rubber stopper, making the depressurization process difficult to control and potentially causing air leakage. In addition, some products are not equipped with an independent depressurization structure, and users can only depressurize by forcibly prying the edge of the lid, which not only poses safety risks but also reduces the product's lifespan.

[0040] The present invention will be further described below with reference to the accompanying drawings.

[0041] like Figures 1 to 7As shown, this embodiment provides a vacuum grain storage bin, including a bin body 1 and a bin lid 2 disposed on the top of the bin body 1. The bin lid 2 includes an upper cover 21 and a lower cover 22. The upper cover 21 is provided with an air extraction component 3, and the lower cover 22 is provided with an air extraction hole 221 and a pressure relief hole 222 communicating with the inner cavity of the bin body 1. The air extraction component 3 is connected to the air extraction hole 221 through a pipeline to extract the air from inside the bin body 1, thereby creating a negative pressure environment, which is beneficial for the long-term preservation of grain and for moisture and insect prevention. The upper cover 21 is also equipped with a pressure relief button 41, which is used to release the negative pressure inside the bucket and make it easier for users to open the lid 2. To achieve this function, a movable rod 4 is provided between the upper cover 21 and the lower cover 22. One end of the movable rod 4 is connected to the pressure relief button 41, and the other end of the movable rod 4 is connected to a sealing plug 42. The sealing plug 42 abuts against the pressure relief hole 222. When the pressure relief button 41 is pressed, the movable rod 4 rotates, pushing the sealing plug 42 to open the pressure relief hole 222, so that the pressure difference inside and outside the bucket is quickly balanced, making it easy to open the lid.

[0042] like Figure 4 and Figure 5 As shown, to achieve the above structure, a rotating shaft 43 is provided in the middle of the movable rod 4, and a rotating bracket 211 is provided on the bottom of the upper cover 21. The rotating shaft 43 is rotatably installed in the connecting hole 2111 of the rotating bracket 211, so that the movable rod 4 can rotate stably and flexibly when the pressure relief button 41 is pressed. An elastic element 44 is also provided between the movable rod 4 and the upper cover 21. One end of the elastic element 44 abuts against the end of the movable rod 4 near the sealing plug 42, and the other end abuts against the upper cover 21, which is used to provide a restoring force so that the sealing plug 42 automatically springs back to its original position when not operated, ensuring that the pressure relief hole 222 is in a sealed state.

[0043] like Figure 3 As shown, the air extraction assembly 3 includes an air extraction housing 31, and an air extraction pump 32, a power supply 33, a control circuit board 34, and a three-way connector 36 disposed inside the housing. The air extraction port 221 is connected to the first end of the three-way connector 36 via a pipe, the air extraction end of the air extraction pump 32 is connected to the second end of the three-way connector 36, and the third end of the three-way connector 36 is connected to a pressure sensor 37 disposed on the control circuit board 34 via a pipe. This sensor is used to monitor the pressure changes inside the tank in real time, thereby automatically controlling the start and stop of the air extraction pump 32 through the control circuit board 34 to achieve intelligent air extraction control. The vacuum housing 31 is provided with a cover plate 38, and the cover plate 38 is provided with a vacuum switch 39 for triggering the trigger button on the control circuit board 34. The user can conveniently control the vacuum function through the vacuum switch 39. The vacuum housing 31 is installed in the mounting groove 212 of the upper cover 21. The inner wall of the mounting groove 212 is provided with an L-shaped stop buckle 2121. The vacuum housing 31 is provided with a stop block 311. After the vacuum housing 31 rotates, the stop block 311 engages with the stop buckle 2121, which is convenient for disassembly and assembly, and allows the user to remove the vacuum assembly 3 for independent charging.

[0044] like Figures 8 to 10 As shown, the barrel 1 is equipped with a detachable measuring container 5 inside. A limit bar 11 is provided on the inner wall of the barrel 1. The measuring container 5 can be stably installed on the limit bar 11, making it convenient for users to scoop out an appropriate amount of grain.

[0045] like Figure 9 As shown, a mesh cover 6 is detachably installed on the bottom surface of the lower cover 22. A desiccant can be placed inside the mesh cover 6 to absorb any residual moisture at the bottom of the container, further keeping the inside dry. The mesh cover 6 is provided with a buckle 62, and the lower cover 22 is provided with a corresponding slot 223. The two are stably connected by a snap-fit ​​method, making installation and replacement very convenient.

[0046] like Figure 10 As shown, in addition, a grain scoop 7 can be detachably installed on the bottom surface of the lower cover 22. The grain scoop 7 is provided with a first magnetic attachment 71, and a second magnetic attachment 224 is provided at the corresponding position on the lower cover 22. The grain scoop 7 is attracted and fixed to the lower cover 22 by magnetic attraction, which not only improves the overall storage neatness, but also prevents the grain scoop 7 from being lost.

[0047] The basic working principle of this utility model is as follows: When in use, the user first opens the lid 2, puts the grain to be stored into the barrel 1, and then closes the lid 2. After ensuring that it is closed, the user presses the air extraction switch 39 on the upper cover 21, the air extraction component 3 starts, the air extraction pump 32 starts running, the air inside the barrel is sucked out through the air extraction hole, and the air pressure sensor 37 monitors the air pressure inside the barrel in real time. When the air pressure reaches the set vacuum state, the control circuit board 34 controls the air pump 32 to automatically stop running. At this time, a vacuum state is formed inside the barrel 1, effectively isolating air, extending the storage time of the grain, and preventing moisture and insects. If the grain needs to be removed, the user presses the pressure relief button 41, the movable rod 4 rotates, and drives the sealing plug 42 to disengage from the pressure relief hole 222. Since the pressure relief hole 222 is connected to the outside atmosphere, the outside air quickly enters the barrel 1 through the pressure relief hole 222, the air pressure inside and outside the barrel is balanced, the negative pressure is released, and the barrel lid 2 can be easily opened. The bottom of the barrel lid 2 also has a detachable grain scoop 7 for easy grain removal. After use, it is sucked back into its original position, keeping it clean and tidy. When the power of the air extraction component 3 is insufficient, the air extraction housing 31 in the upper cover 21 can be unscrewed and charged separately. After being charged, it can be reinstalled and used again.

[0048] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
