Description

Technical Field

[0001] The utility model relates to the field of moisture-proof and dehumidification functions, in particular to a dehumidification bag. Background Art

[0002] A humid environment can cause clothes to become damp, food and other materials to become moldy, and can also affect people's health. Especially in southern my country, there are many rainy days and heavy humidity, so dehumidification equipment is essential. Therefore, moisture-absorbing bags with a compact design and easy use are widely used.

[0003] For example, patent CN 206950936 U discloses a dehumidification hook bag, which includes a moisture absorbing bag and a water collecting bag. The moisture absorbing bag is filled with a moisture absorbent, and the solution formed after being damp is collected in the water collecting bag.

[0004] At present, most of the dehumidification bags on the market adopt such a design, and the advantages of this design are also obvious. The outside of the dehumidifying bag is mostly made of breathable paper or materials with a certain water-locking ability to make the dehumidification effect better; a large amount of desiccant can be placed inside the dehumidifying bag, and the desiccant effect is obvious. The formed solution is uniformly collected in the water collection bag, which will not cause environmental pollution.

[0005] However, the same design has obvious disadvantages: first, the moisture-absorbing bag is usually made of breathable paper material. If the area of ​​breathable paper is too large, the production cost will inevitably increase. A large amount of desiccant needs to be filled in the moisture-absorbing bag. Although the large breathable area can quickly absorb water vapor in the air and make the desiccant deliquesce quickly, it will also cause waste of desiccant, making it difficult to maintain its moisture absorption performance for a long time. Secondly, after the desiccant deliquesces quickly and in large quantities and flows into the water collection bag, the weight of the entire dehumidification bag is increased. For the hanging desiccant bag, it is easy to cause the desiccant bag to fall, resulting in damage to the desiccant bag and spillage of the contents. At the same time, since the water collection bag is generally made of ordinary plastic film material, it has almost no promoting effect on the moisture-absorbing bag except for collecting water. The desiccant that has not been completely deliquesced in the water collection bag is easy to gather at the bottom of the bag, and even form crystals, which can easily cause the bottom of the water collection bag to be punctured. In addition, if the water level in the water collection bag is not designed reasonably, it will also contaminate the desiccant near the water collection bag, resulting in contamination and waste of the desiccant.

[0006] Therefore, in view of the existing design forms of desiccant bags on the market, there is an urgent need for a hanging dehumidification product that can not only ensure or even improve its desiccant effect but also reduce production costs and is suitable for hanging use. Through the reasonable design and improvement of the water collection area in the dehumidification bag, it can also achieve a more obvious promoting effect on the dehumidification function of the dehumidification bag to a certain extent, thereby further improving the dehumidification efficiency of the dehumidification bag. Utility Model Content

[0007] In order to solve the problems mentioned in the background technology and overcome the above shortcomings, the utility model provides the following technical solutions:

[0008] Existing dehumidification bags are usually mainly composed of a bag-like structure with plastic sealing on both sides. The front side is a plastic film, and the back side is generally divided into two sections, the upper part is a breathable paper area, the lower part is a plastic film area, and the middle is separated by a middle seal; there are also self-supporting structures, which increase the bottom surface design; in order to increase the capacity, folded accordion-style sides can also be set; the added bottom and sides are generally waterproof plastic film or other materials.

[0009] The dehumidification bag of the present application is based on the existing dehumidification bag, and the area size of the plastic film area and the breathable paper area on the back of the dehumidification bag is adjusted according to actual needs to fully exert the efficiency of the desiccant.

[0010] On the back of the dehumidification bag, the breathable paper and the plastic film are bonded together using heat sealing technology to form an integrated sheet structure, which is divided into a breathable paper area and a plastic film area according to different materials used.

[0011] Furthermore, the top of the breathable paper area can be replaced by a plastic film to form an upper plastic film area, and the height of the upper plastic film area is no greater than that of the breathable paper area; that is, the back of the dehumidification bag is composed of an upper plastic film area, a middle breathable paper area, and a water collection bag plastic film area in sequence.

[0012] The breathable paper area and the plastic film area below the breathable paper area are collectively referred to as the dehumidification area. The dehumidification area mainly consists of two components: one part is the moisture absorption area, and the other part is the water collection bag. The two parts are separated by a middle seal with water permeable holes. The middle seal is pressed at the breathable paper area. The front and back sides of the dehumidification bag are pressed together by the middle seal to form a pocket structure on the upper part of the dehumidification bag, that is, the area from the top of the breathable paper area to the middle seal is the moisture absorption area, and the part below the middle seal forms an internal hollow structure, which is the water collection bag.

[0013] The water collecting bag is below the moisture absorption zone, and the back of the moisture absorption zone is entirely breathable paper. The breathable paper area extends downward to the water collecting bag through the middle seal position, that is, a part of the water collecting bag is made of breathable paper and a part is plastic film. Below the moisture absorption zone is the breathable paper area of ​​the water collecting bag, and below the breathable paper area of ​​the water collecting bag is the plastic film area of ​​the water collecting bag.

[0014] Since part of the water collecting bag is also made of breathable paper material, such a design increases the range of the breathable paper in the water collecting bag, thereby increasing the overall moisture absorption area of ​​the dehumidification bag. Not only can the upper moisture absorption area absorb moisture, but moisture may also enter the dehumidification bag through the water collecting bag and be absorbed by calcium chloride. Moreover, the calcium chloride entering the water collecting bag is usually not completely deliquesced by moisture absorption. Such a design allows the calcium chloride in the water collecting bag to continue to absorb water vapor in the space using the breathable paper in the water collecting bag, so that the calcium chloride is fully utilized and continues to play a role. In addition, high-concentration calcium chloride solution is easy to crystallize, resulting in puncture of the bottom of the plastic film. The calcium chloride in the water collecting bag continues to absorb water to reduce the concentration of the formed calcium chloride solution, and the diluted calcium chloride solution will not damage the plastic film, thereby reducing the risk of damage to the water collecting bag.

[0015] Furthermore, the height ratio of the breathable paper in the moisture absorption area to the breathable paper in the water collection bag is 1.5 to 2:1.

[0016] Furthermore, a water level line is provided on the water collecting bag. When the solution in the water collecting bag reaches near the water level line, the dehumidification bag needs to be replaced in time to prevent the solution collected in the water collecting bag from reaching near the water permeable holes due to its large amount and contaminating the desiccant at the bottom of the moisture absorption area; at the same time, it can also avoid the situation where the breathable paper is damaged due to the solution collected in the water collecting bag exceeding the load capacity of the breathable paper, causing the solution or other contents therein to leak out.

[0017] Furthermore, the water level line on the water collecting bag is arranged at one third of the water collecting bag from top to bottom.

[0018] After the hygroscopic area is filled with the hygroscopic agent, the top of the pocket structure can be sealed. Such a pocket structure can flexibly adjust and control the filling amount of the hygroscopic agent in the hygroscopic area.

[0019] The moisture absorption area is filled with an appropriate amount of moisture absorbent, such as calcium chloride. When in use, the calcium chloride can absorb moisture in the space through the breathable paper. The solution formed by the deliquescent reaction of the upper calcium chloride flows to the bottom of the moisture absorption area and reaches the position of the middle seal. The middle seal is provided with a water-permeable hole, and the solution flows from the water-permeable hole into the water collection bag below for unified collection and treatment.

[0020] The upper and lower plastic film parts of the three-stage hanging dehumidification bag are both made of plastic film materials. According to actual use needs, holes can be punched in the plastic film area or used in other ways. The upper and lower plastic film areas can also be reasonably designed as needed to improve the overall aesthetics of the three-stage hanging dehumidification bag.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The dehumidification bag of the present application appropriately reduces the area of ​​the breathable paper through reasonable design, but adds a breathable paper area to the water collection bag part, thereby reducing the production cost while ensuring the moisture absorption efficiency of the dehumidification bag: by reducing the area of ​​the breathable paper in the moisture absorption zone, not only the filling amount of the desiccant in the moisture absorption zone is reduced, the weight of the dehumidification bag is reduced to prevent it from falling, but also the moisture absorption speed is easy to control so that the desiccant can fully absorb moisture; at the same time, the height of the breathable paper in the water collection bag part is increased, so that the desiccant that still has a moisture absorption effect in the calcium chloride solution in the water collection bag can continue to play a role, improve the moisture absorption efficiency, stabilize the moisture absorption rate of the entire dehumidification bag, and maximize the utilization of the desiccant.

[0023] 2. Since the solution formed by the desiccant after absorbing moisture is prone to condensation and crystallization when the concentration is high, which will cause the bottom of the water collection bag to be punctured, a part of breathable paper area is also provided on the water collection bag, which not only facilitates the desiccant that has not been completely deliquesced in the water collection bag to continue to absorb moisture, but also can reduce the concentration of the solution formed by the desiccant after absorbing moisture by allowing the desiccant to continue to absorb moisture and deliquesce, thereby reducing the risk of damage to the water collection bag.

[0024] 3. The moisture absorption area and the water collection bag are separated by the middle seal. The solution formed in the moisture absorption area can flow into the water collection bag through the water-permeable holes on the middle seal to avoid contaminating the moisture absorbent. A water level line is also provided on the water collection bag with clear markings for easy observation, and the generated solutions are collected uniformly to avoid environmental pollution.

[0025] 4. By adding the upper plastic sealing area and the water collection bag plastic film area, the design can be carried out according to the actual production and life needs, thereby improving the applicability and aesthetics of the dehumidification bag, making it easier to place and store, and saving space.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0031] Example 1

[0032] The dehumidification bag products currently on the market usually use the middle seal 42 as the dividing line. The part above the middle seal is made of fully breathable paper material to facilitate the moisture absorption of the desiccant. The part below the middle seal is a water collection bag made of full plastic film material to collect the solution produced after the desiccants deliquesce. However, such a design will cause the desiccant to deliquesce quickly and its moisture absorption rate cannot be controlled. A large amount of desiccant will gather at the bottom of the water collection bag to form a supersaturated solution, which not only causes a waste of the desiccant, but also the concentration of the supersaturated solution containing the desiccant is too high, which is easy to produce crystals and easily puncture the bottom of the water collection bag, causing the solution to leak.

[0033] like Figure 1 As shown, the applicant has made a two-stage hanging dehumidification bag to meet market demand. The dehumidification bag is 160 mm long and 300 mm high. The front and bottom surfaces are plastic film, and the back surface is made of breathable paper and plastic film respectively.

[0034] The two-stage hanging dehumidification bag is divided into two parts, upper and lower parts, by a middle seal 42. The part above the middle seal 42 is the moisture absorption area 21, which is made of breathable paper and has a height of 153 mm; the part below the middle seal 42 is a water collection bag, which has a height of 140 mm, of which the height of the breathable paper area 22 of the water collection bag is 7 mm, and the rest is the plastic film area 3 of the water collection bag.

[0035] A lower heat-sealed edge 41 having the same length as the two-stage dehumidification bag is provided between the breathable paper area 22 of the water collecting bag and the plastic film area 3 of the water collecting bag. The height of the lower heat-sealed edge 41 is 15 mm, and the breathable paper and the plastic film are bonded together through the lower heat-sealed edge.

[0036] The middle seal 42 has the same length as the two-stage hanging dehumidification bag, and the height of the middle seal 42 is 7 mm. A number of water-permeable holes 421 are provided on the middle seal 42 at equal distances. During use, the desiccant in the moisture absorption zone 21 absorbs moisture in the space to form a solution which flows into the water collection bag through the water-permeable holes 421 and is collected uniformly by the water collection bag.

[0037] Since a part of the water collecting bag breathable paper area 22 is added to the water collecting bag area, the calcium chloride that is not completely dissolved in the water collecting bag can continue to exert its moisture absorption performance, and at the same time, the concentration of the solution in the water collecting bag can be reduced to avoid the problem of the water collecting bag rupture.

[0038] Example 2

[0039] Based on Example 1, the applicant found that although a breathable paper area 22 of the water collecting bag was set, since the height of the breathable paper area 22 of the water collecting bag was relatively small, while the height of the breathable paper in the moisture absorption area 21 was relatively large, the moisture absorption rate of the moisture absorption area 21 and the continuous effect of calcium chloride in the water collection bag could be further improved.

[0040] In the actual use of the two-stage hanging dehumidification bag in Example 1, calcium chloride is selected as the desiccant, and calcium chloride is fully filled into the moisture absorption area 21. During use, it is found that Figure 1 Although a large amount of calcium chloride can be filled into the two-stage hanging dehumidification bag shown, since the moisture absorption zone 21 is made of breathable paper, the range of the breathable paper is too large and is not suitable for operations such as punching, which is not conducive to the hanging of the dehumidification bag and will also increase the cost of using the breathable paper. At the same time, it is found that since a large amount of calcium chloride is filled in the moisture absorption zone 21, although the moisture absorption rate is very fast, the generated solution flows from the moisture absorption zone 21 to the water collection bag 22. Since the moisture absorption zone 21 is large, the solution will contaminate other calcium chlorides that have not been hydrolyzed during the flow process. Some calcium chloride has not yet fully absorbed moisture and flows into the water collection bag through the middle seal with the solution, resulting in a decrease in its moisture absorption effect. Moreover, since the area of ​​the breathable paper zone 22 of the water collection bag is relatively small, the expectation that the breathable paper in the breathable paper zone 22 of the water collection bag will play a role in enhancing the moisture absorption effect has not met expectations. Therefore, the applicant has improved the product design scheme based on the existing products, that is, a three-stage hanging dehumidification bag of the present application.

[0041] A three-stage hanging dehumidification bag Figure 2 As shown, the dehumidification bag is 160 mm long and 300 mm high, which are the same length and height as the original two-stage dehumidification bag. The front and bottom surfaces are plastic film, and the back surface is made of breathable paper and plastic film respectively.

[0042] like Figure 2 As shown, the height of the upper plastic film area 1 of the three-stage hanging dehumidification bag is 60 mm. The upper plastic film area 1 is added on the original basis to facilitate adaptation to usage scenarios. Holes can be punched or hooks can be added to the upper plastic film area 1 for easy hanging use.

[0043] The top of the breathable paper area is replaced by a plastic film, so the back of the entire dehumidification bag is divided into three parts: upper, middle and lower, which are separated by an upper heat-sealed edge 4 and a lower heat-sealed edge 41, wherein the upper and lower parts are both plastic film areas, and the middle part is a breathable paper area.

[0044] The length of the heat-sealed edge on the back of the dehumidification bag is consistent with the length of the dehumidification bag, and the height can be 12-16 mm. The upper heat-sealed edge 4 and the lower heat-sealed edge 41 are the same as the length of the dehumidification bag, and the height is 15 mm. The heat-sealed edge is used to stick the breathable paper to the plastic film.

[0045] The upper plastic film area of ​​the dehumidification bag, the middle breathable paper area, and the plastic film area of ​​the water collection bag have a height ratio of 1:1 to 1.5:2.

[0046] The part below the upper heat-sealed edge 4 is the dehumidification zone 2, which is composed of a moisture absorption zone 21 and a water collecting bag. The moisture absorption zone 21 is 48 mm high, and the water collecting bag is 170 mm high, wherein the breathable paper zone 22 of the water collecting bag is 37 mm high, and the rest is the plastic film zone 3 of the water collecting bag. The moisture absorption zone 21 is separated from the breathable paper zone 22 of the water collecting bag by a middle seal 42, and the front and back of the dehumidification bag are pressed together by the middle seal 42. The middle seal 42 is the same length as the two-stage hanging dehumidification bag, and the middle seal 42 is 7 mm high. A number of water-permeable holes 421 are provided on the middle seal 42 at equal distances.

[0047] Compared with the original product, although the height of the moisture absorption zone 21 is shortened, the height of the breathable paper zone 22 of the water collecting bag is correspondingly expanded. Since the height of the moisture absorption zone 21 is reduced, the solution formed in the moisture absorption zone 21 can quickly flow into the water collecting bag 22 below through the water permeable hole 421, effectively avoiding the decrease in the moisture absorption effect of calcium chloride caused by the solution, and at the same time reducing the moisture absorption rate to a certain extent, so that the desiccant can slowly play a role and fully absorb; at the same time, since the height of the breathable paper zone 22 of the water collecting bag is increased, and a water level line is set at one-third from top to bottom, it is convenient to observe and replace the dehumidification bag in time. Even if there is more solution in the water collecting bag 22, it will not contaminate the calcium chloride at the bottom of the moisture absorption zone 21. In addition, the water collecting bag 22 is also made of breathable paper, which can be effectively utilized to accelerate the moisture absorption rate.

[0048] The two-stage dehumidification bag in Example 1 is modified into a three-stage hanging dehumidification bag in Example 2, that is, Figure 1 Modified to Figure 2 For the design of adding the upper plastic sealing area 1 on the upper part, it is only necessary to move the top of the breathable paper part on the back downward on the original basis, and the area of ​​the breathable paper can be appropriately adjusted according to needs.

[0049] Example 3

[0050] Based on Example 1 and Example 2, the heights of the moisture absorption area 21 and the breathable paper area 22 of the water collecting bag can also be adjusted individually by moving up the pressing position of the middle seal 42, and the overall height of the breathable paper area can be adjusted according to actual needs, so that the product can be improved in practicality, applicability and aesthetics.

[0051] The improved dehumidification bag of Example 3 has an overall front length of 160 mm and a height of 300 mm. The front and bottom surfaces are made of plastic film, and the back surface is made of breathable paper and plastic film respectively.

[0052] The two-stage hanging dehumidification bag is divided into two parts, an upper part and an lower part, by a middle seal 42. The part above the middle seal 42 is the moisture absorption zone 21, which is made of breathable paper and has a height of 153 mm; the part below the middle seal 42 is a water collection bag, which has a height of 140 mm, wherein the height of the breathable paper zone 22 of the water collection bag is 7 mm, and the rest is the plastic film zone 3 of the water collection bag. The improved dehumidification bag of Example 3 moves the position of the middle seal 42 upward on the basis of the two-stage type, adjusts the height of the moisture absorption zone 21 to 48 mm, and the height of the water collection bag is 170 mm, wherein the height of the breathable paper zone 22 of the water collection bag is 37 mm, and the rest is the plastic film zone 3 of the water collection bag.

[0053] A lower heat-sealed edge 41 of the same length as the two-stage dehumidification bag is provided between the breathable paper area 22 of the water collecting bag and the plastic film area 3 of the water collecting bag. The height of the lower heat-sealed edge 41 is 15 mm. The breathable paper and the plastic film are bonded together through the lower heat-sealed edge. An upper plastic film area can also be added above the breathable paper area on the back side as needed, and the top of the breathable paper is bonded to the bottom of the upper plastic film area with the upper heat-sealed edge 4.

[0054] The middle seal 42 has the same length as the two-stage hanging dehumidification bag, and the height of the middle seal 42 is 7 mm. A number of water-permeable holes 421 are provided on the middle seal 42 at equal distances. During use, the desiccant in the moisture absorption zone 21 absorbs moisture in the space to form a solution which flows into the water collection bag through the water-permeable holes 421 and is collected uniformly by the water collection bag.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
