Description

Technical Field

[0001] This utility model relates to the field of grain storage containers, and more specifically to a vacuum grain storage container. Background Technology

[0002] Vacuum grain storage bins typically use a pivot joint to connect the bin body and the lid, with a sealing ring between them. When a vacuum is drawn inside the bin, the lid moves towards the bin body under the pressure difference, compressing the sealing ring and ensuring the airtightness between the bin body and the lid.

[0003] Existing vacuum grain storage containers typically have a handle at the bottom of the lid. This handle is used to lock the lid and container together when the lid is on top, ensuring a tight seal. However, when a vacuum is applied to the inside of the container, the lid moves towards the container, compressing the sealing ring and reducing the distance between them. Since the locking distance on the handle is usually fixed, when the distance between the lid and container decreases, the handle may lose its ability to lock them together, thus failing to effectively guarantee a tight seal.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, a grain storage bin includes a bin body 100 and a lid 200. A vacuum module 210 is provided inside the lid 200. When the lid 200 covers the top of the bin body 100, the vacuum module 210 is used to extract the air inside the bin body 100 through the lid 200. A snap-fit ​​part 110 extends outward from the top edge of the bin body 100. An elastic sealing element 120 is provided between the bottom of the lid 200 and the top of the snap-fit ​​part 110. One end of the lid 200 is connected to the top of the bin body 100, and the bottom of the other end of the lid 200 is provided with a first hook structure 220 and a second hook structure 230. When the vacuum module 210 is not activated, the first hook structure 220 is snapped into the snap-fit ​​part 110. When the vacuum module 210 is activated, the second hook structure 230 is snapped into the snap-fit ​​part 110.

[0028] In the working state of this embodiment, the container 100 is used to store food, such as pet food. After the food is placed inside the container 100, the lid 200 is placed over the top of the container 100. At this time, the elastic sealing member 120 presses against the bottom of the lid 200 and the top of the locking part 110 respectively. In this state, the first hook structure 220 and the locking part 110 form a snap connection, thereby fixing the lid 200 and the container 100 together. When vacuum preservation is required inside the container, the vacuum module 210 is activated to vacuum the container. When the body 100 is evacuated, the air inside the body 100 is drawn out through the cover 200. Due to the negative pressure inside the barrel, the elastic seal 120 is compressed in this state. At this time, the second hook structure 230 and the hook part 110 form a snap connection, so that the cover 200 and the barrel 100 can continue to be fixed. It should be noted that in this application, the first hook structure 220 and the second hook structure 230 can be installed on the cover 200 or on the barrel 100, and the principle is the same.

[0029] Compared with the prior art, this application provides a first hook structure 220 and a second hook structure 230 at the bottom of the cover 200. When vacuuming is not required, the cover 200 and the barrel 100 are connected by a snap-fit ​​connection to the snap-fit ​​part 110 through the first hook structure 220. When vacuuming is required, the cover 200 and the barrel 100 continue to be connected by a snap-fit ​​connection to the snap-fit ​​part 110 through the second hook structure 230. Thus, this application can maintain good sealing between the barrel 100 and the cover 200 in any state.

[0030] Furthermore, based on the above embodiments, combined with Figure 1 , Figure 2 and Figure 3As shown, a handle 300 is provided inside the cover 200. The handle 300 includes a connecting end 310 and an operating end 320. The connecting end 310 forms a pivot connection with the cover 200. When the cover 200 covers the top of the barrel 100, the locking part 110 is located between the connecting end 310 and the operating end 320. That is, the handle 300 can swing back and forth with the connecting end 310 as the axis toward the locking part 110. The first hook structure 220 and the second hook structure 230 are provided on the side of the operating end 320 facing the locking part 110. Thus, under normal conditions, When the vacuum module 210 is not activated, the operating handle 300 moves toward the locking part 110 of the barrel 100 with the connecting end 310 as the axis, thereby forming a snap connection between the first hook structure 220 and the locking part 110. When the vacuum module 210 is activated, the elastic seal 120 is compressed, and the operating end 320 descends relative to the locking part 110. At this time, the operating handle 300 moves toward the locking part 110 of the barrel 100 with the connecting end 310 as the axis, thereby forming a snap connection between the second hook structure 230 and the locking part 110.

[0031] Furthermore, based on the above embodiments, such as Figure 3 As shown, the first hook structure 220 and the second hook structure 230 extend outwards towards the barrel 100 along a first step 220a and a second step 230a, respectively. The first step 220a is located below the second step 230a, and the length of the first step 220a is greater than the length of the second step 230a. When the vacuum module 210 is not activated, the operating handle 300 is moved towards the locking part 110 of the barrel 100 with the connecting end 310 as the axis, thereby locking the first step 220a at the bottom of the locking part 110, thus securing the cover 200 and the barrel. When the vacuum module 210 is activated, the operating end 320 will descend relative to the locking part 110. At this time, the first step 220a descends, causing the position of the second step 230a to be directly opposite the bottom of the locking part 110. Then, the operating handle 300 can be moved towards the locking part 110 of the barrel 100 with the connecting end 310 as the axis, so that the second step 230a is locked at the bottom of the locking part 110. This allows the barrel 100 and the cover 200 to maintain good sealing performance in any state.

[0032] Furthermore, based on the above embodiments, such as Figure 3As shown, a wrench 330 is provided on the side of the operating end 320 away from the first step 220a and the second step 230a. The wrench 330 is perpendicular to the operating end 320. The wrench 330 is used by the operator to make it easier to move the handle 300 about the connecting end 310 towards the locking part 110 of the barrel 100.

[0033] Furthermore, based on the above embodiments, such as Figure 5 As shown, a first rotating shaft 240 is provided inside the cover 200, and the connecting end 310 is sleeved on the first rotating shaft 240, thereby forming a rotating shaft connection between the handle 300 and the cover 200. An elastic element 250 is provided between the first rotating shaft 240 and the connecting end 310. One end of the elastic element 250 is fixed on the first rotating shaft 240, and the other end contacts the connecting end 310. The elastic element 250 is used to provide elastic force to the handle 300 to move toward the barrel 100. Thus, in this application, regardless of whether a vacuum is drawn, as long as the cover 200 covers the top of the barrel 100, the elastic element 250 can provide elastic force to make its first step 220a or second step 230a engage with the engaging part 110.

[0034] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5 As shown, an air vent 260 is provided at the bottom of the cover 200. The vacuum module 210 includes a vacuum pump 211, which is connected to the air vent 260 and is used to extract air from the barrel 100 through the air vent 260. A control circuit board 212 and a battery 213 are respectively provided on the vacuum pump 211. The battery 213 is electrically connected to the control circuit board 212 and the vacuum pump 211. The control circuit board 212 is used to send corresponding electrical signals to the vacuum pump 211 to control the start and stop of the vacuum pump 211. The specific principle is a well-known technology and will not be described in detail here.

[0035] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5As shown, an air inlet 270 is provided at the bottom of the cover 200, and a sealing member 280 is provided inside the cover 200, covering the top of the air inlet 270. A clamping member 290 is provided outside the sealing member 280, and the sealing member 280 is clamped and suspended at the bottom of the clamping member 290. The clamping member 290 has second rotating shafts 291 at both ends, and a bracket 292 is provided inside the cover 200. The second rotating shafts 291 are sleeved on the bracket 292, so that the clamping member 290 and the bracket 292 form a rotating shaft connection. When it is necessary to break the vacuum state, it is only necessary to operate the clamping member 290 to rotate on the bracket 292, so that the clamping member 290 drives the sealing member 280 to rise and move away from the air inlet 270. In this way, external air can enter the barrel 100 through the air inlet 270, thereby breaking the vacuum state.

[0036] Furthermore, based on the above embodiments, such as Figure 5 As shown, the connecting end 310 has a protrusion 311 extending towards the clamping member 290. The protrusion 311 contacts the top of the clamping member 290 on the side away from the sealing member 280. Thus, when it is necessary to break the vacuum, simply rotate the handle 300 clockwise, causing the protrusion 311 to move downwards relative to the side of the clamping member 290 away from the sealing member 280. This causes the clamping member 290 to lift the sealing member 280 away from the air inlet 270, allowing external air to enter the barrel 100 through the air inlet 270, thereby breaking the vacuum. In this state, the handle 300 can be used not only to drive the first step 220a and the second step 230a, but also to drive the sealing member 280, thus achieving two different functions.

[0037] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
