[0001] The utility model relates to the field of grain storage barrels, and particularly relates to a lid opening structure of a grain storage barrel and a vacuum grain storage barrel thereof. Background Art

[0002] When taking or putting grains in the existing vacuum grain storage barrel, first, the air release operation needs to be carried out, and the lid can be opened only after the air pressure is balanced. This increases the operation steps and time, and it will bring inconvenience to users who frequently take grains. For example, when taking grains for pets, it may be necessary to quickly obtain grains, but due to the separation of air release and lid opening, the whole process becomes lengthy, affecting the use experience. In addition, users may forget to perform the air release operation first and directly open the lid during the use process, which may damage the sealing structure of the grain storage barrel. For example, in a hurry, the lid may be forcibly opened, resulting in deformation or damage of the sealing components, affecting the vacuum performance of the grain storage barrel.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

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

[0027] Now, with reference to the accompanying drawings, a further description of the preferred embodiments of the present utility model will be given. As shown in Figures 1 to 3 A barrel cover opening structure of a grain storage barrel includes a barrel body 10 and a cover body 20 covering the barrel body 10. An air vent 21 is provided at the bottom of the cover body 20. A handle 100 is provided inside the cover body 20. The handle 100 is rotationally connected to the cover body 20 through a first rotating shaft 110. The handle 100 includes a first driving part 120 and a first driven part 130. The first driving part 120 and the first driven part 130 rotate synchronously around the first rotating shaft 110. The first driving part 120 extends to the outside of the cover body 20. A lever transmission member 200 is provided on one side of the first driven part 130. A sealing member 210 is provided on the side of the lever transmission member 200 away from the handle 100. The sealing member 210 plugs the air vent 21. A lever linkage is formed between the handle 100 and the lever transmission member 200 to drive the lever transmission member 200 to rotate clockwise, so that the sealing member 210 is disengaged from the air vent 21.

[0028] When those in the art are using it, in combination with Figure 4 and Figure 5As shown, the barrel body 10 is in a vacuum state. Therefore, under the pressure difference between the inside and outside, the cover body 20 is pressed on the barrel body 10. At this time, the seal 210 blocks the ventilation hole 21. The user first controls the first driving part 120 to rotate counterclockwise, and the first driven part 130 also rotates counterclockwise around the first rotating shaft 110. Since a lever linkage is formed between the handle 100 and the lever transmission part 200, the lever transmission part 200 can be pressed to rotate in the reverse direction, that is, drive the lever transmission part 200 to rotate clockwise. Since the seal 210 is arranged on the side away from the handle 100, when the lever transmission part 200 rotates clockwise, the seal 210 will be driven to rise, so as to disengage from the ventilation hole 21, so that air can enter the barrel body 10 from the gap of the cover body 20, so that the pressure inside and outside the barrel body 10 is balanced, and the cover body 20 can be opened. Compared with the prior art, in this application, the barrel body 10 can be deflated while the cover body 20 is opened, and there is no need to separately set a deflation structure at other positions of the cover body 20. One structure realizes two functions at the same time, which greatly simplifies the structure and production cost of the cover body 20 while facilitating the user to open the cover body 20.

[0029] Furthermore, on the basis of the above embodiments, in combination with Figure 3 and Figure 5 As shown, the lever transmission part 200 is rotationally connected to the cover body 20 through the second rotating shaft 220. The lever transmission part 200 includes a second driving part 230 and a second driven part 240. The second driving part 230 is located below the first driven part 130. In this way, when the user controls the first driving part 120 to rotate counterclockwise, the first driven part 130 also rotates counterclockwise around the first rotating shaft 110, so that the second driving part 230 can be pressed to rotate clockwise, and then drive the second driven part 240 to rotate clockwise around the first rotating shaft 110, driving the seal 210 to rise, so as to disengage from the ventilation hole 21.

[0030] In some embodiments, as Figure 5 shown, there is a gap 250 between the second driving part 230 and the first driven part 130, which can prevent the user from accidentally touching the handle 100 and then controlling the lever transmission part 200 to operate the seal 210 to disengage from the ventilation hole 21, thereby further improving the stability of the structure.

[0031] Furthermore, on the basis of the above embodiments, in combination with Figure 3 and Figure 5As shown, a support cover 22 is provided inside the cover body 20. The support cover 22 covers the ventilation hole 21 and forms a receiving cavity 23 above the ventilation hole 21. A limiting plate 24 is provided inside the receiving cavity 23. The top of the limiting plate 24 is connected to the second driven part 240. The sealing member 210 is provided at the bottom of the limiting plate 24. In this way, the second driven part 240 will drive the limiting plate 24 and the sealing member 210 to lift and lower synchronously. Since the limiting plate 24 is located inside the receiving cavity 23, the lifting and lowering range of the limiting plate 24 and the sealing member 210 will be limited by the receiving cavity 23, thereby preventing the sealing member 210 from rising too high and causing it to be unable to re-seal the ventilation hole 21 again.

[0032] In some embodiments, as Figure 5 shown, a first spring 25 is further provided between the top of the limiting plate 24 and the top of the receiving cavity 23. When the second driven part 240 drives the limiting plate 24 and the sealing member 210 to lift synchronously, the first spring 25 is compressed. When the second driven part 240 drives the limiting plate 24 and the sealing member 210 to lower synchronously, the first spring 25 will provide pressure to the limiting plate 24, so that the sealing member 210 can better seal the ventilation hole 21.

[0033] Furthermore, on the basis of the above embodiments, as Figure 5 shown, the top of the cover body 20 is bent downward to form a first bending part 26. A second spring 260 is provided between the first bending part 26 and the first driving part 120. When the user first controls the first driving part 120 to rotate counterclockwise, the second spring 260 is compressed. When the user disengages from the first driving part 120, the second spring 260 will provide pressure to the first driving part 120 to keep it restored to its original state, thereby further preventing the user from accidentally touching the handle 100.

[0034] Furthermore, on the basis of the above embodiments, as Figure 5 shown, a second bending part 11 is further bent outward at the top of the barrel body 10. A buckle groove 140 is provided on the handle 100. The buckle groove 140 is buckled with the second bending part 11. In this way, when the barrel body 10 is in a vacuum state, the cover body 20 will sink under the action of the internal and external pressure difference to form a self-suction effect with the barrel body 10. At this time, the buckle connection between the buckle groove 140 and the second bending part 11 can further improve the sealing performance between the barrel body 10 and the cover body 20. When the cover body 20 needs to be opened, the user controls the first driving part 120 to rotate counterclockwise to disengage the buckle connection between the buckle groove 140 and the second bending part 11.

[0035] The present application also provides a vacuum grain storage barrel applying the barrel cover opening structure of the above grain storage barrel, as Figure 1As shown, it includes a barrel body 10 and a cover body 20. A vacuum pump 27 and a battery box 28 for supplying power to the vacuum pump 27 are provided inside the cover body 20. The way of setting a vacuum pump 27 inside the cover body 20 is prior art and will not be elaborated here.

[0036] Furthermore, on the basis of the above-mentioned embodiment, as Figure 5 shown, a sealing ring 12 is provided between the barrel body 10 and the cover body 20. When the barrel cover covers the barrel body 10, the vacuum pump 27 is started to make the inside of the barrel body 10 in a vacuum state. At this time, the cover body 20 squeezes the barrel body 10 inward. Under the action of the internal and external pressure difference, the cover body 20 will sink to form a self-suction effect with the barrel body 10, thereby compressing the sealing ring 12 and further improving the sealing effect.

[0037] Details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
