Description

Technical Field

[0001] This application relates to the field of mechanical tooling technology, and in particular to a deoxidation device. Background Technology

[0002] The aging process of tobacco leaves under controlled atmosphere (CA) technology requires continuous changes in the oxygen concentration inside the protective cover used to seal the tobacco stacks. The tobacco stacks typically undergo three stages inside the protective cover: CA anti-mold and insect control, CA aging, and CA preservation. CA anti-mold and insect control requires a low-oxygen environment with an oxygen concentration of less than or equal to 2% inside the protective cover. CA aging requires a re-oxygen environment with an oxygen concentration of about 8% inside the protective cover. CA preservation requires a low-oxygen environment with an oxygen concentration of less than or equal to 2% inside the protective cover. The low-oxygen environment is achieved by adding an oxygen absorber.

[0003] Modified atmosphere packaging (MAP) for mold and insect control typically requires a conditioning period of at least two years, as does modified atmosphere aging. Therefore, the oxygen absorber placed inside the protective enclosure becomes largely ineffective after these two processes. When entering the modified atmosphere preservation stage, a new oxygen absorber needs to be added to the enclosure. The traditional method involves damaging the protective enclosure, adding the new oxygen absorber, and then repairing and resealing it. This process is time-consuming and labor-intensive, impacting the convenience of oxygen absorber application. Utility Model Content

[0004] One of the technical problems addressed by this application is how to improve the ease of use of deoxygenation devices.

[0005] A deoxidizing device is used to install within a protective cover of a sealed smoke stack, the deoxidizing device comprising:

[0006] Load-bearing components;

[0007] Mounting component, which is connected to the carrier component and is used for mounting inside the protective cover;

[0008] A deoxidizing unit, comprising a sealed bag and a deoxidizing agent, wherein the deoxidizing agent is contained within the sealed bag; and

[0009] An unlocking component is connected to the sealed bag and is used to unlock the sealed bag to open it.

[0010] In one embodiment, there are multiple deoxygenation units, which are spaced apart on the carrier.

[0011] In one embodiment, the sealed bag includes a bag body and a locking body, the deoxidizer is contained within the bag body, and the locking body is disposed on the bag body and seals the bag body.

[0012] In one embodiment, the bag body includes two spaced-apart receiving pieces, the locking body includes a protrusion, the protrusion protruding from one of the receiving pieces and located within the bag body, the other receiving piece has a groove, the protrusion and the groove cooperate to seal the bag body, and the unlocking element is disposed on the receiving piece.

[0013] In one embodiment, the accommodating piece has a connecting portion, which is the portion of the accommodating piece located between one end of the bag body opening and the protrusion or the groove, and the unlocking member is disposed on the connecting portion.

[0014] In one embodiment, the dimension of the connecting portion in the length direction of the sealed bag is 0.8 mm to 1.5 mm.

[0015] In one embodiment, the unlocking element includes a rivet and a pull ring, the rivet being connected to the receiving piece and the pull ring being disposed on the rivet.

[0016] In one embodiment, the sealing bag has fixing points located at both ends in the width direction of the sealing bag, and the fixing points are thermally fused to the carrier.

[0017] In one embodiment, the carrier is a plastic composite film.

[0018] In one embodiment, the mounting component includes a mounting part and a hook, the carrier is fixedly connected to the mounting part, and the hook is connected to the mounting part and used to hang inside the protective cover.

[0019] One technical advantage of one embodiment of this application is that, given that the deoxygenation device includes an unlocking mechanism, it can be placed inside the protective cover while it is sealed. When the tobacco stack enters the modified atmosphere storage stage, the sealed bag can be opened via the unlocking mechanism without damaging the protective cover, ensuring that the deoxygenating agent inside the sealed bag deoxygenates the gas within the space enclosed by the protective cover, thereby reducing the oxygen concentration within that space to the range required for the modified atmosphere storage stage. This simplifies the operation of the deoxygenation device, eliminating the need to damage and reseal the protective cover, thus improving the ease of use of the device and the deoxygenating agent. Furthermore, it avoids the drawback of increased oxygen concentration caused by damage to the protective cover, ensuring that less deoxygenating agent is consumed during the modified atmosphere storage stage of the tobacco stack, ultimately reducing the processing cost of the modified atmosphere storage stage.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0034] Referring to Figure &, an embodiment of this application provides a deoxidation device 10 for installation inside a protective cover of a sealed tobacco stack. The protective cover can be made of flexible materials, such as plastic. After the protective cover is fitted over the tobacco stack from top to bottom, the lower end of the protective cover can be heat-sealed, thus providing a good seal for the tobacco stack. Therefore, the protective cover can provide a good environment for modified atmosphere storage, mold and insect control, modified atmosphere aging, and modified atmosphere preservation of the tobacco stack.

[0035] The deoxygenation device 10 includes a support member 100, a mounting member 200, a deoxygenation unit 300, and an unlocking member 400. The mounting member 200 is connected to the support member 100 and is installed within a sealed space enclosed by a protective cover. For example, the mounting member 200 can be installed on the tobacco stack or on the protective cover. The deoxygenation unit 300 includes a sealed bag 310 and a deoxygenating agent, with the deoxygenating agent contained within the sealed bag 310. The unlocking member 400 is connected to the sealed bag 310 and is used to unlock the sealed bag 310 to open it. When the tobacco stack enters the modified atmosphere storage stage, given the flexibility of the protective cover, it is possible to allow the user to simultaneously hold the protective cover and the unlocking member 400 without damaging the cover. That is, the user can apply force to the unlocking member 400 through the protective cover, thereby unlocking the sealed bag 310. Once unlocked, the sealed bag 310 will be in an open state, meaning that the containment space of the sealed bag 310 is connected to the space enclosed by the protective cover. This allows the deoxygenating agent in the containment space to deoxygenate the gas in the space enclosed by the protective cover, thereby reducing the oxygen concentration in the space enclosed by the protective cover to a set range.

[0036] If the protective cover is damaged and the deoxidizer is directly added inside, it would require several steps. First, the cover needs to be damaged, the deoxidizer added, and then the cover resealed using a heat-sealing method. This process would be extremely labor-intensive, making the addition of the deoxidizer time-consuming and costly, thus affecting the convenience of deoxidation treatment. Second, damage to the cover would allow outside air to enter, disrupting the original environment and increasing the concentration of deoxidizer inside. This would require more deoxidizer during the controlled atmosphere storage stage of the smokestack, thereby increasing the processing cost of this stage.

[0037] The deoxygenation device 10 in the above embodiments can be placed inside the protective cover while it is being sealed. When the tobacco stack enters the modified atmosphere storage stage, the sealing bag 310 can be opened via the unlocking component 400 without damaging the protective cover. This ensures that the deoxygenating agent inside the sealing bag 310 deoxygenates the gas in the space enclosed by the protective cover, thereby reducing the oxygen concentration in the space enclosed by the protective cover to the range required for the modified atmosphere storage stage. This simplifies the operation of the deoxygenation device 10, eliminating the need to damage and reseal the protective cover, thus improving the ease of use of the deoxygenation device 10 and the convenience of the deoxygenating agent's deoxygenation process. Furthermore, it avoids the drawback of increased oxygen concentration caused by damage to the protective cover, ensuring that less deoxygenating agent is consumed during the modified atmosphere storage stage of the tobacco stack, ultimately reducing the processing cost of the modified atmosphere storage stage.

[0038] In some embodiments, the carrier 100 can be a plastic composite film, such as a PVC composite film. The length of the carrier 100 can be approximately 1000 mm, the width of the carrier 100 can be approximately 250 mm, and the thickness of the carrier 100 can be approximately 0.08 mm. The mounting component 200 includes a mounting part 210 and a hook 220. The carrier 100 is fixedly connected to the mounting part 210. For example, one end of the carrier 100 can be wound around the crossbar 211 of the mounting part 210, so that the carrier 100 is fixedly connected to the crossbar 211 of the mounting part 210 by heat fusion, thereby suspending the carrier 100 on the mounting part 210. The hook 220 is connected to the mounting part 210. The hook 220 can be connected to the chimney stack or protective cover, so that the hook 220 is suspended on the chimney stack or protective cover, thereby allowing the entire mounting component 200 to be hung inside the protective cover, and also allowing the carrier 100 to be hung inside the protective cover. In other embodiments, the mounting part 210 can be fixed inside the protective cover by means of adhesive bonding or snap-fit ​​connection.

[0039] In some embodiments, the sealing bag 310 may be made of plastic material, with a length of approximately 300 mm, a width of approximately 200 mm, and a thickness of approximately 0.2 mm. Multiple sealing bags 310 may be arranged at intervals along the suspension direction of the support member 100, i.e., along the vertical direction. The spacing between any two adjacent sealing bags 310 may be equal, for example, approximately 20 mm. Generally, three sealing bags 310 may be arranged at intervals on the support member 100. By providing multiple sealing bags 310, sufficient deoxidizer is contained within the deoxidizing device 10, ensuring that the deoxidizer reduces the oxygen concentration within the protective cover to the required range.

[0040] In some embodiments, the sealed bag 310 has fixing points 311b located at both ends in the width direction of the sealed bag 310. The fixing points 311b are fixedly connected to the carrier 100, for example, the fixing points 311b and the carrier 100 can be heat-fused together. For example, the sealed bag 310 and the carrier 100 can be heated and pressurized by a high-temperature clamping machine, thereby causing the molecules of the sealed bag 310 and the carrier 100 to undergo structural changes under the action of heat and pressure, ultimately causing the fixing points 311b of the sealed bag 310 to be heat-fused together with the carrier 100, thus effectively fixing the sealed bag 310 to the carrier 100. In other embodiments, the sealed bag 310 can also be fixedly connected to the carrier 100 by adhesive bonding.

[0041] In some embodiments, the sealed bag 310 includes a bag body 311 and a locking body 312. The deoxidizer is contained within the accommodating space enclosed by the bag body 311, and the locking body 312 is disposed on the bag body 311 and seals the bag 310 body. When a force is applied to the unlocking member 400, the locking body 312 can be unlocked, thereby making the bag body 311 and the entire sealed bag 310 in an open state. That is, the accommodating space enclosed by the bag body 311 is interconnected with the space enclosed by the protective cover, effectively ensuring that the deoxidizer in the bag body 311 deoxidizes the space enclosed by the protective cover to reduce the oxygen concentration.

[0042] In some embodiments, the bag body 311 includes two receiving pieces 311a, which are spaced apart along the thickness direction of the bag body 311. The locking body 312 includes a protrusion 312a located within the receiving space of the bag body 311, such that the protrusion 312a protrudes from one of the receiving pieces 311a along the thickness direction. A groove is recessed on the other receiving piece 311a, forming an open slot along the thickness direction of the receiving piece 311a. When the protrusion 312a and the groove engage, they form an interlocking relationship, thereby sealing the opening of the sealed bag 310, thus achieving a sealing treatment of the sealed bag 310. The unlocking element 400 is disposed on the receiving piece 311a. When force is applied to the unlocking element 400, the protrusion 312a can be disengaged from the groove, thereby releasing the engagement between the protrusion 312a and the groove, and thus releasing the locking and sealing effect of the locking body 312 on the bag body 311. In other embodiments, the locking body 312 can also be a structure such as double-sided adhesive, as long as the locking body 312 can lock and unlock the receiving space of the sealed bag 310.

[0043] In some embodiments, the receiving piece 311a has a connecting portion 311c, which is the portion of the receiving piece 311a located between one end of the receiving piece 311a at the opening of the bag body 311 and the protrusion 312a or the groove. An unlocking member 400 is disposed on the connecting portion 311c. During the unlocking process of the locking body 312, an outward pulling force can be applied to the connecting portion 311c by the unlocking member 400, thereby causing the protrusion 312a to disengage from the groove, thus unlocking the locking body 312 and leaving the sealed bag 310 in an open state. In other embodiments, the unlocking member 400 may also be disposed at other locations on the receiving piece 311a, as long as the lock body can be unlocked by the unlocking member 400.

[0044] In some embodiments, the dimension of the connecting portion 311c in the length direction of the sealed bag 310 is 0.8 mm to 1.5 mm. For example, the dimension of the connecting portion 311c in the length direction of the sealed bag 310 can be 0.8 mm, 1 mm, or 1.5 mm, etc. This ensures that there is sufficient installation space on the connecting portion 311c to accommodate the unlocking member 400, and also allows the unlocking member 400 to quickly disengage the protrusion 312a from the groove, thus achieving rapid unlocking of the locking body 312.

[0045] In some embodiments, the unlocking member 400 includes a rivet 410 and a pull ring 420. The rivet 410 is fixedly connected to the receiving piece 311a, and the pull ring 420 is disposed on the rivet 410. The pull ring 420 may be annular. During operation, the user can pinch the protective cover and engage the pull ring 420 with their fingers, allowing the fingers to easily apply force to the pull ring 420. This causes the pull ring 420 to disengage the protrusion 312a from the groove through the rivet 410 and the connecting portion 311c, thus achieving quick unlocking of the locking body 312.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
