detailed description

Fig. 1 is a schematic structural view of a storage box according to an embodiment of the present invention, and Fig. 2 is a schematic structural exploded view of a storage box according to an embodiment of the present invention. Referring to Fig. 1 and Fig. 2, a storage space for storing articles is defined in the storage box 1, and the storage box 1 may be roughly in the shape of a cuboid.

In particular, the storage box 1 further includes a humidity regulating device 10 and a function switching device. The humidity adjustment device 10 has a moisturizing module 11 for increasing or maintaining the humidity of the storage space and a drying module 12 for reducing the humidity of the storage space. The function switching device is disposed in a cavity 41 formed outside the storage box 1 , and includes a knob 21 rotatably installed in the cavity 41 . The bottom of the cavity 41 defines a bottom notch 412 adjacent to the bottom wall 411 of the cavity 41 , that is, the bottom wall 411 and the bottom notch 412 together form the bottom of the cavity 41 . Both the moisturizing module 11 and the drying module 12 are fixed on the inner surface of the knob 21 facing the concave cavity 41, so that at least part of the moisturizing module 11 or at least part of the drying module 12 are exposed to the reservoir through the bottom gap 412 of the concave cavity 41 as the knob 21 rotates. The storage space in the storage box 1 can selectively make the storage box 1 work in a moisturizing mode or a drying mode. That is to say, the moisturizing module 11 and the drying module 12 can rotate with the rotation of the knob 21 , so that during the rotation, one of the moisturizing module 11 and the drying module 12 is exposed to the storage space through the bottom gap 412 . When the moisturizing module 11 rotates to the position aligned with the bottom notch 412 to be exposed to the storage space, the storage box 1 works in the moisturizing mode; when the drying module 12 rotates to the position aligned with the bottom notch 412 to be exposed to the storage space , the storage box 1 works in the drying mode. Specifically, the knob 21 has a grip portion 211 protruding upward from its upper surface, so that the user can apply force to the knob 21 to rotate through the grip portion 211 .

Thus, the user can rotate the moisturizing module 11 and the drying module 12 by rotating the knob 21 to change the position of the moisturizing module 11 and the drying module 12 relative to the bottom notch 412, so that the moisturizing module 11 or the drying module 12 passes through the cavity 41. The bottom notch 412 exposes the storage space in the storage box 1 . When the moisturizing module 11 is exposed to the storage space, the storage box 1 works in the moisturizing mode, and when the drying module 12 is exposed to the storage space, the storage box 1 works in the dry mode, so that the same storage space can be dry and wet. purpose of use. Both the moisturizing mode and the drying mode of the storage box 1 are realized by the humidity adjustment device 10 without any external parts, so the storage box 1 of the present invention can be used as an independent storage device, which can be placed on In air-cooled refrigerators, direct-cooled refrigerators, freezers or other storage devices, the storage box 1 of the present invention can even be directly placed in an indoor environment, and has a wide range of applications.

At the same time, since the storage box 1 can be freely switched between its moisturizing mode and drying mode by manually rotating the knob 21 outside the storage box 1, no other operations or other structures are required, so in the present invention, the storage box The switching process between the moisturizing mode and the drying mode of the box 1 is simpler and more convenient.

Furthermore, the storage box 1 of the present invention drives the rotation of the moisturizing module 11 and the drying module 12 through the rotation of the knob located in the concave cavity 41 outside the storage box, thereby completely covering the moisturizing module 11 or the drying module 12 through the bottom wall 411 of the concave cavity 41. Completely covering the drying module 12 to realize the drying mode or moisturizing mode of the storage box 1 , simplifies the structure of the storage box 1 .

In some embodiments of the present invention, the moisturizing module 11 is configured to allow the moisture in the storage space to permeate to the external environment through it when the humidity in the storage space is greater than a predetermined humidity threshold. When the humidity in the storage space is below the predetermined humidity threshold, the moisture in the storage space is prevented from penetrating into the external environment through it, and the moisture in the external environment is allowed to penetrate into the storage space through it, until the humidity in the storage space reaches Predetermined humidity threshold. Specifically, in some embodiments of the present invention, the moisturizing module 11 has micropores that allow moisture to pass through in both directions. Microscopically, no matter whether the humidity in the storage space is greater than the predetermined humidity threshold, part of the moisture in the storage space penetrates into the external environment through the moisturizing module 11 and part of the moisture in the external environment penetrates into the storage space through the moisturizing module 11 . When the humidity in the storage space is below the predetermined humidity threshold, the amount of moisture penetrating from the storage space to the external environment is smaller than the amount of moisture penetrating from the external environment to the storage space. At this time, macroscopically, the moisturizing module 11 can be considered to prevent the moisture in the storage space from penetrating into the external environment through it, and allow the moisture in the external environment to permeate into the storage space through it.

Further, the drying module 12 is configured to reduce humidity in the storage space by absorbing moisture in the storage space. That is to say, the drying module 12 is a hygroscopic drying module that reduces the humidity of the storage space by absorbing moisture in the storage space.

In some embodiments of the present invention, the moisturizing module 11 may include at least one moisture-permeable membrane with a predetermined moisture-permeable threshold, and the drying module 12 may include at least one plate-shaped component made of hygroscopic material. Preferably, the drying module 12 in the embodiment of the present invention may include a plurality of plate-shaped components 121 made of hygroscopic materials, and the multiple plate-shaped components 121 are stacked to improve the moisture absorption capacity of the drying module 12 . Of course, in other embodiments of the present invention, when the moisturizing module 11 can also include multiple moisture-permeable films, the multiple moisture-permeable films can be stacked or arranged side by side, and the predetermined moisture permeability thresholds of the multiple moisture-permeable films can be the same. , can also be different.

In some embodiments of the present invention, both the moisturizing module 11 and the drying module 12 are disposed adjacent to or close to the inner surface of the knob 21 . That is to say, the moisturizing module 11 and the drying module 12 can both extend parallel to the inner surface of the knob 21, that is, the moisturizing module 11 and the drying module 12 can extend in the horizontal direction and be adjacent to each other. The inner surfaces of the knob 21 do not overlap.

Further, a ventilation hole 212 is opened in at least a part of the area of the knob 21 opposite to the moisturizing module 11 , so that the storage space communicates with the external environment through the ventilation hole 212 . When the moisturizing module 11 is exposed to the storage space through the bottom gap 412 , moisture can permeate back and forth between the storage space and the external environment through the moisturizing module 11 and the ventilation hole 212 .

Specifically, the handle portion 211 on the knob 21 may extend along the diameter of the circular outer surface of the knob 21 , so as to divide the surface area of the knob 21 into two semicircular areas with approximately the same area. The moisturizing module 11 and the drying module 12 can be respectively fixed on the inner surface of the knob 21 in areas corresponding to the two semicircular areas. The ventilation hole 212 can be opened in a semicircular area corresponding to the moisturizing module 11 .

In some embodiments of the present invention, the storage box 1 further includes a box body 30 with an upward opening and a cover body 40 used to cover the upward opening, and the mating interface between the box body 30 and the cover body 40 forms an airtight Sealing to prevent moisture from entering and leaving the storage space from the mating interface of the box body 30 and the cover body 40, so that the storage space can achieve a sealed environment or a high-humidity environment with controllable humidity. Specifically, an annular sealing ring (not shown in the figure) may be provided at the mating interface between the cover body 40 and the box body 30 to achieve an airtight seal between the two.

Further, the cavity 41 may be formed on the outer side of the cover 40 or any sidewall of the box body 30 . That is to say, the cavity 41 can be located on the top or side of the storage box 1 . Preferably, in the embodiment of the present invention, the cavity 41 is formed on the outside of the cover 40 , that is, on the top of the storage box 1 , so as to facilitate switching of the storage mode (dry mode or moisturizing mode) of the storage box 1 . Specifically, the concave cavity 41 can be recessed into the storage space from the outer surface of the cover body 40 .

In some embodiments of the present invention, the surface area of the bottom wall 411 of the concave cavity is greater than or equal to the cross-sectional area of any module in the moisturizing module 11 and the drying module 12, so that the moisturizing module 11 or the drying module 12 is concaved with the rotation of the knob 21. The bottom wall 411 of the cavity 41 is completely covered. That is to say, the bottom wall 411 of the cavity 41 extends along the horizontal direction and is located below the moisturizing module 11 and the drying module 12 . When the knob 21 is rotated to a certain position, the moisturizing module 11 can be completely or partially exposed to the storage space of the storage box 1 through the bottom gap 412 of the cavity 41 , and at this time, the bottom wall 411 of the cavity 41 completely covers the drying module 12 , storage box 1 is in moisturizing mode. When the knob 21 is rotated to another position, the drying module 12 can be completely or partially exposed to the storage space of the storage box 1 through the bottom gap 412 of the cavity 41, and the bottom wall 411 of the cavity 41 completely covers the moisturizing module. 11. Storage box 1 is in drying mode. The moisturizing module 11 and the drying module 12 can be in any feasible shape, such as sector, circle, square, rhombus or any irregular shape.

In some embodiments of the present invention, the center of the bottom of the concave cavity 41 is provided with a mounting portion 413 for rotational connection with the knob 21, and the bottom wall 411 of the concave cavity 41 is centered on the center of the mounting portion 413 and adjacent to A fan-shaped wall on the periphery of the mounting portion 413 . Those skilled in the art should understand that the bottom of the cavity 41 refers to the area formed by the bottom wall 411 and the bottom notch 412 of the cavity 41 . Specifically, in the embodiment of the present invention, the concave cavity 41 may be approximately a cylindrical cavity, and its bottom is approximately circular, that is, the area formed by the bottom wall 411 and the bottom notch 412 is approximately circular. The center of the bottom of the concave cavity 41 is an area that spreads outward around the center of the circular bottom. The area may be a circular area, that is, the cross section of the mounting portion 413 may be substantially circular with a central through hole. The cavity bottom wall 411 and the mounting portion 413 can be integrally formed, or can be assembled to form a whole.

Further, the sector angle of the bottom wall 411 of the cavity 41 may be 180°. That is to say, the inner edge of the bottom wall 411 is adjacent to or overlaps with the outer semi-circumferential edge of the mounting portion 413, and the outer edge of the bottom wall 411 is centered on the center of the mounting portion 413 and the outer side of the bottom wall 411 with the center of the mounting portion 413. The distance from the edge is that the semicircle of the radius coincides. In other words, the bottom wall 411 may be a semicircular ring concentric with the installation part 413 and located on the periphery of the installation part 413 . The inner edge of the bottom wall 411 is the curved edge of the bottom wall 411 close to the mounting portion 413 , and the outer edge of the bottom wall 411 is the curved edge of the bottom wall 411 away from the mounting portion 413 .

In some embodiments of the present invention, both the moisturizing module 11 and the drying module 12 are generally fan-shaped plates with the center of the installation part 413 as the center, that is, both are generally fan-shaped plates concentric with the installation part 413 . The sector angle of the moisturizing module 11 and the sector angle of the drying module 12 are both 180°, and the distance between the inner edge of the moisturizing module 11 and the distance between the inner edge of the drying module 12 and its outer edge is less than or equal to the bottom of the concave cavity 41 The distance from the inside edge of the wall 411 to its outside edge. The distance between the inner edge of the moisturizing module 11 and the outer edge thereof in the present invention means the difference between the distance between the center of the mounting part 413 and the distance between the center of the mounting part 413 and the distance from the inner edge of the moisturizing module 11 , that is, the vertical distance between the inner edge of the moisturizing module 11 and its outer edge. The distance between the inner edge of the drying module 12 and its outer edge is similar to the distance between the inner edge of the moisturizing module 11 and its outer edge, and will not be repeated here.

Specifically, the moisturizing module 11 and the drying module 12 may be arranged such that their inner edges meet end to end to form a first circle, and their outer edges meet end to end to form a second circle. The area between the first circumference and the second circumference overlaps with the area covered by the bottom of the cavity 41 up and down. That is to say, both the moisturizing module 11 and the drying module 12 are semicircular rings with the same shape and cross-sectional area as the bottom wall 411 , and the moisturizing module 11 and the drying module 12 form an almost complete ring on the inner surface of the knob 21 .

Those skilled in the art should understand that in other embodiments of the present invention, the fan angles of the bottom wall 411 of the concave cavity 41, the moisturizing module 11 and the drying module 12 are not all limited to 180°, and may be less than 180°, or may be Both are greater than 180°, and the sector angle of the bottom wall 411 may be greater than 180°, and the sector angle of the moisturizing module 11 and the drying module 12 is less than or equal to 180°. The fan angle between the bottom wall 411 of the concave cavity 41, the moisturizing module 11 and the drying module 12 can be the same or different, as long as the angle of the fan angle of the concave cavity bottom wall 411 is greater than or equal to the moisturizing module 11 and the drying module 12 The angle of the sector angle is enough.

Referring to FIG. 3 , the knob 21 further includes a cylindrical side wall 213 extending from its inner surface toward the cavity 41 , and the cylindrical side wall 213 defines an area for fixing the moisturizing module 11 and the drying module 12 inside. The cylindrical sidewall 213 protrudes into the cavity 41 and is in close contact with the sidewall of the cavity 41 . This not only allows the knob 21 to rotate in the concave cavity 41 , but also ensures that an airtight seal is formed between the knob 21 and the concave cavity 41 to a certain extent. Therefore, when the bottom wall 411 of the cavity covers the moisturizing module 11 , the moisturizing module 11 is completely isolated from the storage space, and a strictly sealed dry environment is formed in the storage box 1 . When the cavity bottom wall 411 covers the drying module 12, the drying module 12 is completely isolated from the storage space, so as to prevent the drying module 12 from absorbing moisture in the storage space when the storage box 1 is in the moisturizing mode.

The bracket 221 and the bracket 222 can be located under the moisturizing module 11 and the drying module 12 respectively, and ventilation holes are opened on the bracket 221 and the bracket 222, so that the moisturizing module 11 and the drying module 12 communicate with the storage space. In order to facilitate the fixed connection between the bracket 221 and the bracket 222 and the knob 21, the moisturizing module 11 and the drying module 12 can be provided with a gap or a through hole for the connecting piece to pass therethrough. The size of the gap or the through hole is relatively small, which hardly affects the moisturizing module. 11 and the overall appearance shape of drying module 12.

Further, both the bracket 221 and the bracket 222 may be generally fan-shaped brackets with a fan angle of 180°, and the fan-shaped brackets may be provided with buckles for locking with the cover 40 . The bracket 221 and the bracket 222 can be plastic brackets to reduce their weight, thereby reducing the overall weight of the storage box 1 .

A sealing ring (not shown) similar in shape to the edge of the concave cavity bottom wall 411 may be provided to further improve the sealing performance between the bottom wall 411 and the moisturizing module 11 or the drying module 12 .
