Description

Technical Field

[0001] The utility model relates to the field of exhaust structures, in particular to an exhaust structure of a double-layer barrel and a vacuum grain storage barrel thereof. Background Art

[0002] The barrel body of the existing vacuum grain storage barrel is usually single-layer. The barrel body is used to store food in a vacuum state. However, if the food needs to be taken out, it may be necessary to repeatedly open the barrel body to break the vacuum state of the barrel body, which will affect some foods that need to be stored for a long time.

[0003] After the improvement, the barrel body mostly adopts a double-layer barrel body, that is, the inner barrel body is sleeved in the outer barrel body. When the inner and outer barrel bodies are vacuumed at the same time, the inner barrel body cannot be taken out from the outer barrel body, which causes great inconvenience to the user when storing food. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an exhaust structure of a double-layer barrel body, comprising an inner barrel body and an outer barrel body, the inner barrel body being arranged in the outer barrel body, the side walls between the inner barrel body and the outer barrel body being gap-fitted, a through hole being opened on the side wall of the inner barrel body, a blocking piece being attached to the inner wall of the inner barrel body, the blocking piece being fitted on one side of the through hole, a limiting piece being arranged on the side of the blocking piece away from the through hole, a spring being arranged between the blocking piece and the limiting piece, a rotating piece being arranged around the blocking piece, a rotating handle being connected to the rotating piece, a lifting structure being arranged in the rotating piece, and when the rotating piece drives the lifting structure to rotate synchronously, the blocking piece is lifted toward the side away from the through hole by the lifting structure.

[0005] Furthermore, the lifting structure includes a raised portion and a recessed portion arranged at intervals in the rotating member, the raised portion protrudes toward a side away from the through hole, and the blocking member includes a blocking portion and a contact portion extending along the blocking portion toward the rotating member.

[0006] Furthermore, the number of the contact portions is two, and they are symmetrically arranged along both sides of the blocking portion.

[0007] Furthermore, a guide member is provided between the blocking member and the limiting member, and the guide member is annular, with one end of the guide member arranged around the blocking member and the other end being in contact with the limiting member. A guide groove is provided on the guide member, and the guide groove is provided between the blocking member and the limiting member, and the contact portion is provided in the guide groove.

[0008] Furthermore, a top plate is provided on a side of the limiting member away from the guide member, and the top plate is fixed on a side of the rotating member away from the through hole.

[0009] Furthermore, a silicone sheet is provided at the bottom of the sealing portion.

[0010] Furthermore, a guide column is provided in the middle of the guide member, and a guide hole is provided on the blocking member.

[0011] The present application also provides a vacuum grain storage barrel using the above-mentioned double-layer barrel exhaust structure, including a cover body covering the inner barrel body and the outer barrel body, wherein a vacuum pump and a battery box are arranged in the cover body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. When the outer barrel is in a vacuum state, under the action of the pressure difference between the inside and the outside, the side wall of the outer barrel will be tightly attached to the side wall of the inner barrel, so that the inner barrel and the outer barrel cannot be separated. At this time, the spring is in a compressed state, and the blocking piece is pressed against the through hole by one end of the spring, while the other end of the spring abuts against the limit piece. When the rotating member drives the lifting structure to rotate, the blocking piece is lifted to the side away from the through hole by the lifting structure, so that it can no longer be attached to the through hole, so that air can flow between the inner barrel and the outer barrel through the through hole, so that the pressure difference between the inside and the outside is balanced, so that the inner barrel can be taken in and out of the outer barrel.

[0014] 2. The inner barrel can be used to place some more commonly used foods, so that in daily use, you only need to open the lid to take things out of the inner barrel. When you need to take out the food in the outer barrel, you can operate the rotating handle to remove the vacuum state of the outer barrel and take the inner barrel out of the outer barrel.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] 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.

[0031] The preferred embodiment of the present invention will be further described with reference to the accompanying drawings. Figures 1 to 4 As shown, the exhaust structure of the double-layer barrel body includes an inner barrel body 10 and an outer barrel body 20, wherein the inner barrel body 10 is arranged in the outer barrel body 20, and the side walls between the inner barrel body 10 and the outer barrel body 20 are in a clearance fit, a through hole 11 is opened on the side wall of the inner barrel body 10, and a blocking member 100 is attached to the inner wall of the inner barrel body 10, wherein the blocking member 100 is attached to one side of the through hole 11, and a limiting member 200 is provided on the side of the blocking member 100 away from the through hole 11, wherein the blocking member 100 and the limiting member 200 are in a clearance fit ... A spring (not shown in the figure) is provided between the parts 200, and a rotating part 300 is provided around the blocking part 100. The rotating part 300 is connected to a rotating handle 30. The user can drive the rotating part 300 to rotate around the blocking part 100 by operating the rotating handle 30. A lifting structure is provided in the rotating part 300. When the rotating part 300 drives the lifting structure to rotate synchronously, the blocking part 100 is lifted toward the side away from the through hole 11 by the lifting structure.

[0032] When the outer barrel body 20 is in a vacuum state, under the action of the internal and external pressure difference, the side wall of the outer barrel body 20 will be tightly attached to the side wall of the inner barrel body 10, so that the inner barrel body 10 and the outer barrel body 20 cannot be separated. At this time, the spring is in a compressed state, and the sealing member 100 is pressed against the through hole 11 by one end of the spring, while the other end of the spring abuts against the limit member 200. When the rotating member 300 drives the lifting structure to rotate, the sealing member 100 is lifted up by the lifting structure to the side away from the through hole 11, so that it can no longer be attached to the through hole 11, so that air can flow into between the inner barrel body 10 and the outer barrel body 20 through the through hole 11, so that the internal and external pressure difference is balanced, so that the inner barrel body 10 can be taken in and out of the outer barrel.

[0033] On the basis of the above embodiment, Figure 3 and Figure 4 As shown, the lifting structure includes a protrusion 310 and a recessed portion 320 arranged at intervals in the rotating member 300, the protrusion 310 protrudes toward the side away from the through hole 11, and the blocking member 100 includes a blocking portion 110 and a contact portion 120 extending along the blocking portion 110 toward the rotating member 300. Under normal circumstances, the contact portion 120 is located in the recessed portion 320. At this time, the blocking member 100 is pressed against the through hole 11 by one end of the spring. When the rotating member 300 begins to rotate around the blocking member 100, after the protrusion 310 contacts the contact portion 120, since the protrusion 310 protrudes toward the side away from the through hole 11, the blocking member 100 is lifted toward the side away from the through hole 11 by the protrusion 310, so that it can no longer be attached to the through hole 11, so that air can flow into the outer barrel body 20 through the through hole 11.

[0034] In some embodiments, as Figure 3 As shown, there are two contact portions 120, which are symmetrically arranged along both sides of the blocking portion 110. In this way, the blocking member 100 is pushed up by the protrusion 310 to the side away from the through hole 11, so that the blocking member 100 can be more balanced when being pushed up, so that air can flow better between the inner barrel body 10 and the outer barrel body 20 through the through hole 11.

[0035] On the basis of the above embodiment, Figure 5 and Figure 6As shown, a guide member 400 is provided between the blocking member 100 and the limiting member 200, and the guide member 400 is annular, with one end of the guide member 400 arranged around the blocking member 100, and the other end being fitted with the limiting member 200. A guide groove 410 is provided on the guide member 400, and the guide groove 410 is provided between the blocking member 100 and the limiting member 200, and the contact portion 120 is provided in the guide groove 410. In this way, when the blocking member 100 is pushed up to the side away from the through hole 11 by the protrusion 310, the contact portion 120 can continue to move along the guide groove 410, thereby avoiding the blocking member 100 from being deflected when moving, which may make it impossible to recover.

[0036] In some embodiments, combined Figure 2 and Figure 7 As shown, a top plate 500 is provided on the side of the limiting member 200 away from the guide member 400, and the top plate 500 is fixed on the side of the rotating member 300 away from the through hole 11, so that the top plate 500 can support the limiting member 200 from the side of the limiting member 200 away from the blocking member 100, thereby preventing the spring from being compressed again after the blocking member 100 is pushed up, thereby causing the limiting member 200 to be dislocated.

[0037] In some embodiments, combined Figure 2 and Figure 7 As shown, a silicone sheet 130 is provided at the bottom of the sealing portion 110. Since silicone itself has elasticity, when the spring is in a compressed state and the sealing portion 110 is pressed against the through hole 11 by one end of the spring, the silicone sheet 130 can utilize the characteristics of the silicone material itself to deform, thereby achieving a better pressing effect.

[0038] In some embodiments, as Figure 6 As shown, a guide column 420 is further provided in the middle of the guide member 400, and a guide hole 140 is provided on the blocking member 100. When the blocking member 100 is in the guide member 400, the guide column 420 is inserted into the guide hole 140. In this way, when the blocking member 100 is pushed toward the side away from the through hole 11 by the protrusion 310, the guide hole 140 can move along the guide column 420, thereby avoiding the blocking member 100 from deflecting when moving, which may make it impossible to restore.

[0039] The present application also provides a vacuum grain storage barrel using the exhaust structure of the double-layer barrel body, such as Figure 8 As shown, it includes a cover body 40 covering the inner barrel body 10 and the outer barrel body 20, and a vacuum pump 41 and a battery box 42 for providing power to the vacuum pump 41 are arranged in the cover body 40. The vacuum pump 41 is arranged in the cover body 40 for vacuuming. This is the existing technology and will not be described here.

[0040] like Figure 8 As shown, when the cover 40 covers the inner barrel body 10 and the outer barrel body 20, the vacuum pump 41 is started to make the inner barrel body 10 and the outer barrel body 20 in a vacuum state at the same time. At this time, the cover 40 is opened to make the vacuum state of the inner barrel body 10 contact, but under the action of the pressure difference between the inside and the outside, the side wall of the outer barrel body 20 will be tightly attached to the side wall of the inner barrel body 10, so that the outer barrel body 20 is still in a vacuum state. At this time, the exhaust structure in the above embodiment can be utilized to operate the rotating handle 30 to balance the internal and external pressures, so that the inner barrel body 10 can be taken in and out of the outer barrel.

[0041] In this way, the inner barrel body 10 can be used to place some more commonly used foods, so that in daily use, one only needs to open the lid body 40 to take things out of the inner barrel body 10. When it is necessary to take out the food in the outer barrel body 20, the vacuum state of the outer barrel body 20 can be removed by operating the rotating handle 30, and the inner barrel body 10 can be taken in and out of the outer barrel.

[0042] The above exemplary embodiments are detailed, and the present invention may be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included within the present invention.
