[0027] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0028] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.
[0029] See also Figure 1-5 As shown, this embodiment provides a drying box that is easy to carry, including a box body 1, an electric heating element 21 arranged in the box body 1, and a box cover 2. The box body 1 includes an inner box body 12 and an outer box body 11. The inner box body 12 and the outer box body 11 are both open at the top. The box cover 2 is hinged at the top of the outer box body 11 and is used to cover the top opening of the outer box body 11.
[0030] The inner box 12 is sleeved in the outer box 11 and can move vertically relative to the outer box 11. At this time, the inner box 12 and the outer box 11 are equivalent to a vertically retractable box 1 structure as a whole, and the vertical here can also be understood as the height direction of the box 1.
[0031] The relative vertical movable structure of the outer box 11 and the inner box 12 is as follows: Figure 1 As shown, a through hole 111 is provided on the bottom plate of the outer box 11 for the inner box 12 to vertically move through. The shape and size of the through hole 111 and the inner box 12 are substantially the same, so that the outer peripheral wall of the inner box 12 slides against the peripheral wall of the through hole 111.
[0032] It is worth mentioning that in order to keep the box cover 2 in a closed state when carrying the transfer box 1 or performing drying operations, in this embodiment, a locking structure is provided between the outer box body 11 and the box cover 2, wherein the locking structure can be a buckle structure on some bags on the market, or a magnetic buckle structure, which is not specifically limited here.
[0033] In this embodiment, Figure 3 As shown, the electric heating element 21 preferably adopts an electric heating wire, which is embedded in the box cover 2; of course, in other optional embodiments, the electric heating element 21 can also be embedded in the peripheral wall of the outer box body 11 and / or the peripheral wall of the inner box body 12, which is not specifically limited here.
[0034] The drying box provided in this embodiment further includes legs 3 that can be folded relative to the box body 1 .
[0035] The drying box provided in this embodiment can switch between a first state and a second state, specifically:
[0036] In the first state, the drying box Figure 1 and Figure 3 As shown, the inner box 12 is retracted in the outer box 11, and the inner box 12 is basically completely contained in the outer box 11; and the support leg 3 is folded at the bottom of the outer box 11 and supports the inner box 12. At this time, the support leg 3 is equivalent to a limiter to limit the inner box 12 from falling out of the bottom of the outer box 11.
[0037] In the second state, the drying box Figure 2 and Figure 4 As shown, the bottom of the inner box 12 extends downward from the bottom of the outer box 11, and the inner box 12 is suspended on the outer box 11, and the support legs 3 are unfolded at the bottom of the outer box 11 to support the entire box 1. Specifically, a convex portion 121 protruding outward is provided on the peripheral wall of the inner box 12. In the second state, the inner box 12 is mounted on the bottom plate of the outer box 11 through the convex portion 121.
[0038] In this embodiment, Figure 3 As shown, the protrusion 121 is preferably a skirt disposed on the top of the inner box body 12 .
[0039] It is worth noting that in the second state, if Figure 4 As shown, the bottom of the inner box body 12 is suspended, that is, the lower end of the support leg 3 is lower than the bottom of the inner box body 12 .
[0040] By designing the box 1 as an outer box 11 and an inner box 12 that can move vertically relative to each other, the box 1 is similar to a vertically retractable box 1 structure; in this way, when some taller devices need to be dried, the box 1 can be switched to the second state, at which time the entire box 1 is supported by the unfolded legs 3, and the inner box 12 extends from the bottom of the outer box 11, thereby increasing the height of the entire box 1 to accommodate the drying of taller devices.
[0041] When it is necessary to carry or dry smaller devices, the box 1 can be switched to the first state, in which the inner box 12 is basically completely retracted in the outer box 11. The height of the entire box 1 is basically the height of the outer box 11 plus the thickness of the box cover 2, thereby reducing the height of the entire box 1 and the volume for easy carrying.
[0042] Moreover, in the first state, the box 1 can also be used to dry some smaller devices. In this state, the internal space of the box 1 is reduced, which is equivalent to compressing the internal space of the box 1, so that the heat generated by the electric heating element 21 can be closer to the devices in the box 1, which is beneficial to improving the drying efficiency.
[0043] In this embodiment, the legs 3 are preferably in two groups, which are respectively hinged to the two lateral sides of the bottom of the outer box body 11; the two legs 3 are basically symmetrically arranged. The lateral direction here refers to the direction perpendicular to the vertical direction.
[0044] In addition, in order to facilitate carrying the entire drying box, a handle 5 can be provided on the peripheral wall of the outer box body 11 for a person to hold.
[0045] The support leg 3 is flipped relative to the outer box body 11 to achieve folding or unfolding; for example, in this embodiment, the support leg 3 includes two arms 31 and a crossbeam 32 fixed between the two arms 31, and one end of each of the two arms 31 is hinged to the bottom of the outer box body 11.
[0046] The support leg 3 is in the folded state. Figure 1 As shown, the legs 3 are placed together at the bottom of the outer box body 11 and are arranged horizontally. It is worth noting that at this time, the bottom surface of the entire leg 3 does not protrude from the bottom surface of the outer box body 11, for example, the two are flush with each other, so as to ensure that the box body 1 can be stably placed on the workbench when the legs 3 are in the folded state.
[0047] In addition, the support leg 3 is in the unfolded state. Figure 4 As shown, an angle A is formed between the support leg 3 and the vertical plane, wherein 60°≥angle A≥0°. At 0°, the two support legs 3 are both in a vertical state, and when the angle is greater than 0°, preferably 30° or 45°, the two support legs 3 can be in an eight-shape, thereby being able to support the box body 1 more stably.
[0048] In this embodiment, an unlockable locking assembly is provided on the bottom wall of the inner box body 12; the locking assembly is used to lock the supporting leg 3 after the supporting leg 3 is folded to prevent the supporting leg 3 from unfolding.
[0049] Among them, combined Figure 1 and Figure 5 As shown, the locking assembly includes a shell 41 fixed on the bottom wall of the inner box body 12, wherein when the two legs 3 are in a folded state, the cross beams 32 of the two legs 3 are spaced apart to form a spacing space, and the shell 41 is located in the spacing space.
[0050] The housing 41 is provided with bolts 42 corresponding to the two legs 3 on both sides, and the crossbeam 32 of the legs 3 is provided with a hole 321 for the bolt 42 to be inserted horizontally. When the bolt 42 is inserted into the hole 321, the legs 3 are restricted by the bolt 42 and cannot rotate, thus achieving locking; preferably, two bolts 42 are provided on each side of the housing 41, and two holes 321 corresponding to the two bolts 42 on the same side are provided on the corresponding crossbeam to improve the locking effect.
[0051] In this embodiment, the latches 42 are all slidably disposed in the housing 41 in a transverse direction, so that the latches 42 can move in a transverse direction relative to the housing 41 to enter / exit the insertion hole 321. When the latches 42 are pulled out transversely from the insertion hole 321, the lock is unlocked, and the support leg 3 can be turned freely; conversely, when the latches 42 are inserted into the insertion hole 321, the support leg 3 is locked.
[0052] In order to keep the latch 42 in the insertion hole 321 stably, the locking assembly further includes an elastic member, which is used to provide elastic force to drive the latch 42 to move toward the side close to the insertion hole 321, so that the latch 42 is kept in the insertion hole 321 under the elastic force of the elastic member. The elastic member can be a spring 43.
[0053] The specific structure of the locking assembly is as follows: Figure 5As shown, a mounting cavity 411 is provided in the shell 41; two sliders 44 capable of sliding laterally are slidably provided in the mounting cavity 411, and the inner ends of the latches 42 on both sides are respectively fixed on the two sliders 44; a spring 43 is provided in the mounting cavity 411 and is located between the two sliders 44, and the two ends of the spring 43 are respectively fixedly connected or abutted with the two sliders 44, so that the elastic force of the spring 43 makes the two sliders 44 have a tendency to move away from each other laterally, thereby driving the latches 42 on both sides to move outward laterally.
[0054] In order to facilitate the extraction of the latch 42 from the socket 321 to achieve unlocking, in this embodiment, the locking assembly also includes an unlocking portion 45, which is relatively fixed to the latch 42 and can move laterally relative to the shell 41; the unlocking portion 45 at least partially extends out of the shell 41 for pressing.
[0055] For example, in this embodiment, the unlocking portion 45 is in the shape of a plate, which is slidably inserted into the shell 41 in the transverse direction, with one end extending out of the shell 41 and the other end fixedly connected to the slider 44. When unlocking is required, the unlocking portion 45 is pressed inward in the transverse direction, so that the two sliders 44 can be pushed to overcome the elastic force of the spring 43 and move closer to each other, and then the slider 44 can drive the pin 42 to be pulled out of the socket 321 to achieve unlocking.
[0056] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
