Description

Technical Field

[0001] The utility model relates to the field of packaging bags, in particular to a packaging bag with a drying function. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, aiming to facilitate the transportation and storage of goods during the production and circulation processes. Packaging bags are widely used in daily life and industrial production, and their types include woven bags, mesh bags, container bags, composite bags, etc.

[0003] A packaging bag includes a bag body, handles located on the front and back sides of the bag body, and a receiving cavity inside the bag body. By placing the items to be carried in the receiving cavity and then lifting the handles, the items inside the bag body can be lifted. For items that need to be moisture-proof, such as electronic components, medicines, and foods, being directly placed in the receiving cavity for a long time may directly damage or deteriorate the above items. Therefore, how to dehumidify the items located in the packaging bag to keep them dry has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a packaging bag with a drying function, in which the humid air reaching the receiving cavity can enter the reaction chamber and be absorbed by the desiccant, and thus will not stay in the receiving cavity for a long time.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a bag body and handles located on the front and back sides of the bag body. A receiving cavity is provided inside the bag body. It also includes a left drying part, a right drying part, and a cover located in the receiving cavity. The left drying part includes a reaction chamber, an absorption chamber, a partition located between the reaction chamber and the absorption chamber, and a cover body located at the top of the bag body. The upward projection of the reaction chamber falls on the cover, and the cover is detachably connected to the bag body. A number of through holes with diameters smaller than the desiccant are provided on the partition, with the upper sides communicating with the reaction chamber and the lower sides communicating with the absorption chamber. A number of sealing covers are provided above the reaction chamber of the left drying part, and a number of ventilation holes equal to the number of the sealing covers are provided on the left side of the reaction chamber. The diameter of each ventilation hole is smaller than the diameter of the desiccant. Each of the sealing covers is located on the right side of the corresponding ventilation hole and is detachably connected to the bag body.

[0006] The utility model is further provided as follows: Each of the ventilation holes includes a circulation section and a matching section. Each of the circulation sections is located on the left side of the corresponding matching section, and each of the circulation sections is arranged in a constricted shape from left to right.

[0007] The utility model is further provided as follows: The bag body is fixedly installed with a first magic tape inside each of the matching sections. Each of the sealing covers includes an installation section adapted to the shape of the matching section and a contact section located on the right side of the installation section with a diameter larger than that of the installation section. A second magic tape is provided on each of the installation sections corresponding to each first magic tape.

[0008] The utility model is further configured as follows: an installation seat is arranged above the left drying part of the bag body, the cover is rotatably installed on the installation seat, a first magnet is fixedly installed at the bottom of the cover, and a second magnet is arranged on the bag body corresponding to the first magnet.

[0009] The utility model is further configured as follows: disassembly and assembly parts are arranged on both the left and right sides of the handle, and each disassembly and assembly part is located in the accommodation cavity. Each disassembly and assembly part is arranged in a conical shape. An insertion groove for inserting the handle is arranged on the bag body. The diameter of each insertion groove is smaller than the maximum diameter of the disassembly and assembly part and larger than the diameter of the end face of the handle.

[0010] The utility model is further configured as follows: a deformation space is arranged in each of the disassembly and assembly parts.

[0011] The utility model is further configured as follows: each of the disassembly and assembly parts includes a matching part that abuts against the bag body. A plurality of positioning columns protrude from the matching part, and positioning grooves are arranged on the bag body corresponding to the positioning columns.

[0012] By adopting the above technical solutions, for items such as electronic components, medicines, and foods that need moisture protection, after placing them in the accommodation cavity and then installing the cover on the upper part of the bag body, it is difficult for external moisture to enter the accommodation cavity across the cover. At this time: 1. Since a desiccant is installed in the reaction chamber, the moisture in the accommodation cavity can enter the reaction chamber through each ventilation hole and react with the desiccant. Depending on the type of desiccant, different effects will be produced. For example, if silica gel is selected, the water vapor molecules in the air in the accommodation cavity will be attracted by the surface of the silica gel and enter. As time goes by, the silica gel will gradually adsorb more moisture. When the silica gel is saturated, it can be regenerated by taking it out and heating, that is, promoting the evaporation of water molecules in the silica gel. If the desiccant is calcium chloride, after it absorbs water vapor, it will form a liquid and then enter the absorption chamber through the through holes on the partition board, that is, the water vapor can react with calcium chloride to combine and produce a liquid to reach the absorption chamber. That is, by selecting different desiccants, the water vapor molecules in the accommodation cavity can enter the left drying part and will not adhere to the surface of the items for a long time to cause deterioration. Also, because the upward projection of the reaction chamber will fall on the cover and the cover is detachably connected to the bag body, when it is necessary to replace the desiccant and pour out the liquid in the reaction chamber (after completely taking out the items in the accommodation cavity), by removing the cover, the desiccant can be taken out, replenished, and the liquid can be poured out; 2. Since each sealing cover is detachably connected to the bag body, before the accommodation cavity of the bag body is filled with items, if the sealing cover is not removed, water vapor will not enter the reaction chamber through each ventilation hole, and resource waste will not occur.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Such as Figures 1-9As shown, the utility model discloses a packaging bag with a drying function, comprising a bag body 1 and handles 2 located at the front and rear sides of the bag body 1, wherein a receiving chamber 11 is arranged in the bag body 1, and the bag body 1 and the internal articles can be moved by placing the objects to be stored in the receiving chamber 11 and lifting the handles 2, and further comprising a left drying part 3, a right drying part 4, a sealing cover 5 and a cover body 6 located at the top of the bag body 1, wherein the inner wall of the cover body 6 abuts against the bag body 1, the left drying part 3 comprises a reaction chamber 31 filled with a desiccant such as calcium chloride, silica gel, etc., an absorption chamber 32 and a partition 33 located between the reaction chamber 31 and the absorption chamber 32, the upward projection of the reaction chamber 31 falls on the sealing cover 5, and the sealing cover 5 and the bag body 1 are connected by magnetic attraction, Velcro, etc. Removable connection, the partition 33 is provided with a plurality of through holes 331 whose upper side is connected to the reaction chamber 31 and whose lower side is connected to the absorption chamber 32, and whose diameter is smaller than that of the desiccant, the left drying part 3 is provided with a plurality of sealing covers 534 located above the reaction chamber 31, and a plurality of air holes 35 with the same number as the sealing covers 534 are provided on the left side of the reaction chamber 31, and the diameter of each air hole 35 is smaller than that of the desiccant, and each sealing cover 534 is located on the right side of the corresponding air hole 35 and is detachably connected to the bag body 1 by means of Velcro, magnetic attraction, etc. For electronic components, medicines, foods and other objects that need to be moisture-proof, they are placed in the accommodating chamber 11 and then the cover body 6 is installed above the bag body 1, so that it is difficult for external moisture to pass through the cover body 6 and enter the accommodating chamber 11. At this time: 1. Since the reaction chamber 31 is filled with a desiccant, the moisture in the accommodating chamber 11 can enter the reaction chamber 31 through the air holes 35 to react with the desiccant. Different types of desiccant will produce different effects: if silica gel is used, the water vapor molecules in the air in the accommodating chamber 11 will be attracted by the surface of the silica gel and enter. As time goes by, the silica gel will gradually absorb more moisture. When the silica gel is saturated, it can be taken out and heated to regenerate it, that is, the water molecules in the silica gel are caused to evaporate. If the desiccant is calcium chloride, it will form a liquid after absorbing the water vapor and then enter the absorption chamber 32 through the through hole 331 on the partition 33, that is, the water vapor can react with the calcium chloride to produce a liquid that reaches the absorption chamber 32. That is, different desiccants are selected to enable the water vapor molecules in the accommodating chamber 11 to enter the left drying part 3 without adhering to the surface of the article for a long time to deteriorate it. Because the upward projection of the reaction chamber 31 will fall on the cover 5 and the cover 5 is detachably connected to the bag body 1, when it is necessary to replace the desiccant and pour out the liquid in the reaction chamber 31 (after the articles in the accommodating chamber 11 are completely taken out), the cover 5 can be removed to remove and replenish the desiccant and pour out the liquid; 2. Because each sealing cover 534 is detachably connected to the bag body 1, before the accommodating chamber 11 of the bag body 1 is filled with articles, the sealing cover 534 is not removed to prevent water vapor from entering the reaction chamber 31 through the air holes 35 and causing waste of resources.

[0031] Preferably, each of the air holes 35 includes a flow section 351 and a matching section 352, and each of the flow sections 351 is located on the left side of the corresponding matching section 352, and each of the flow sections 351 is configured to be narrowed from left to right. Since the flow section 351 of each air hole 35 is configured to be expanded from left to right, water vapor molecules located in the accommodating chamber 11 can enter the flow section 351 of the air hole 35 more smoothly and efficiently during use. Since the right side of each flow section 351 is the part with the smallest diameter, it is difficult for desiccant such as calcium chloride and silica gel located in the reaction chamber 31 to cross the flow section 351 and enter the accommodating chamber 11, thereby further improving the stability of the desiccant located in the reaction chamber 31.

[0032] The bag body 1 is located in each matching section 352 and is fixedly installed with a first magic tape 12 by bonding or other means. Each sealing cover 534 includes a mounting section 341 that is adapted to the shape of the matching section 352 and a contact section 342 that is located on the right side of the mounting section 341 and has a diameter larger than that of the mounting section 341. Each mounting section 341 is provided with a second magic tape 3411 corresponding to each first magic tape 12. Since the bag body 1 is located in each matching section 352 and is provided with a first magic tape 12, when the desiccant in the left drying section 3 does not need to be activated, it is not necessary to remove the second magic tape 3411. The sticker 3411 is attached to each sealing cover 534 on the bag body 1. After the moisture-proof object is placed in the accommodating cavity 11, the second Velcro 3411 on the corresponding mounting section 341 is driven by contacting each contact section 342 and then bending the contact section 342 to separate it from the corresponding first Velcro 12 and then activate each air hole 35, so that after the cover body 6 is placed on the bag body 1, the water vapor in the accommodating cavity 11 can pass through the air holes 35 and then react with the desiccant in the reaction chamber 31, thereby achieving adsorption of the water vapor in the accommodating cavity 11.

[0033] In addition, the bag body 1 is provided with a mounting seat 13 above the left drying part 3, the cover 5 is rotatably mounted on the mounting seat 13, the bottom of the cover 5 is fixedly mounted with a first magnet 51 by bonding or the like, and the bag body 1 is provided with a second magnet 14 corresponding to the first magnet 51. Since the cover 5 is rotatably mounted on the mounting seat 13, when there is no need to remove or replenish the desiccant, unrelated personnel will not flip the cover 5 upwards. At this time, the first magnet 51 of the cover 5 is attracted with the second magnet 14 on the bag body 1, so that the cover 5 is stably located above the reaction chamber 31, and the desiccant will not leave the bag body 1. When it is necessary to remove or replenish the desiccant, the desiccant can be removed and replaced by flipping the cover 5 upwards, and after ensuring that the objects in the accommodating chamber 11 are completely taken out, the inverted bag body 1 can enable the liquid in the absorption chamber 32 to reach the reaction chamber 31 through the through holes 331 and then pass over the flip cover and separate from the bag body 1.

[0034] The left and right sides of the handle 2 are provided with disassembly parts 21, and each disassembly part 21 is located in the accommodating cavity 11. Each of the disassembly parts 21 is arranged in a conical shape. The bag body 1 is provided with a loading groove 15 for the handle 2 to be inserted. The diameter of each loading groove 15 is smaller than the maximum diameter of the disassembly part 21 and larger than the diameter of the end face of the handle 2. Since each disassembly part 21 on the handle 2 is located in the accommodating cavity 11 and the diameter of the loading groove 15 is smaller than the maximum diameter of the disassembly part 21, when the handle 2 is inserted, the handle 2 is inserted into the bag body 1. When the handle 2 is loaded into the bag body 1, each disassembly and assembly part 21 needs to forcibly pass over the corresponding loading groove 15 so that each disassembly and assembly part 21 is stably located in the accommodating cavity 11 and abuts against the bag body 1. Similarly, when the handle 2 needs to be removed from the bag body 1, the disassembly and assembly part 21 is bent so that it is forcibly passed over the loading groove 15 and separated from the bag body 1. The conical disassembly and assembly part 21 enables it to be aligned with the loading groove 15 more smoothly and pass over the loading groove 15 to abut against the bag body 1.

[0035] Preferably, each of the disassembly and assembly parts 21 is provided with a deformation space. Since each of the disassembly and assembly parts 21 is provided with a deformation space, when the handle 2 is removed from the bag body 1, the disassembly and assembly part 21 can be more smoothly moved to separate from the loading groove 15.

[0036] Among them, each of the disassembly and assembly parts 21 includes a matching part 212 that abuts against the bag body 1, and a plurality of positioning posts 2121 are protrudingly provided on the matching part 212. The bag body 1 is provided with a positioning groove 16 corresponding to each positioning post 2121. Since the disassembly and assembly part 21 can be inserted into the corresponding positioning groove 16 after forcibly crossing the loading groove 15, the disassembly and assembly part 21 located in the accommodating cavity 11 cannot be rotated compared with the bag body 1, so that the disassembly and assembly part 21 can be stably located in the bag body 1. When it is necessary to separate the handle 2 from the bag body 1, it is necessary to first separate each positioning post 2121 from the corresponding positioning groove 16 and then the disassembly and assembly part 21 can be pried to separate it from the corresponding loading groove 15.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
