[0051] In this embodiment, the ventilation holes 3 on the bottom shell 1 and the upper cover 2 can allow air to pass through to achieve double-sided moisture absorption. The ventilation holes 3 are designed to prevent desiccant leakage, and the desiccant will not leak out through the ventilation holes 3. When the air carrying water vapor enters the installation cavity surrounded by the upper cover 2 and the bottom shell 1, the water vapor in the air will be absorbed by the desiccant. At the same time, the air carrying water vapor will also enter the display window assembly, and the color-changing desiccant will absorb the water vapor in the air. When the desiccant is full of water vapor, the color-changing desiccant in the display window assembly will also be full of water vapor. The color-changing desiccant in the display window assembly turns into the first color. The user can judge the state of the dehumidifier according to the color of the color-changing desiccant. The dehumidifier is small in size and can be suitable for dehumidification in small spaces.

[0052] In one embodiment, the upper cover 2 cooperates with the bottom shell 1 to form a flat structure.

[0053] In this embodiment, since the upper cover 2 cooperates with the bottom shell 1 to form a flat structure, the dehumidifier is small in size and can be used for dehumidification in a small space.

[0054] Specifically in one embodiment, Figure 1 and Figure 2 As shown, the bottom shell 1 and the upper cover 2 are shaped like a tennis racket.

[0055] The bottom surface of the bottom shell 1 is a curved surface with a small curvature. The side wall of the bottom shell 1 is an arc surface except for a flat surface at one end. The shape of the edge of the upper cover 2 is the same as that of the edge of the bottom shell 1.

[0056] Specifically in one embodiment, the ventilation hole 3 is a strip-shaped hole, and the size of the desiccant in all directions is larger than the width of the ventilation hole 3, ensuring that the desiccant will not leak out from the ventilation hole 3. In addition, the ventilation hole 3 is a strip-shaped hole, which can increase the area of ​​the ventilation hole 3, making the air flow smoother and improving the dehumidification efficiency.

[0057] Specifically in one embodiment, the ventilation hole 3 is a strip-shaped hole, the width of the ventilation hole 3 is less than 2 mm, and the diameter of the desiccant is 3 mm, ensuring that the desiccant will not leak out from the ventilation hole 3. In addition, the ventilation hole 3 is a strip-shaped hole, which can increase the area of ​​the ventilation hole 3, make the air flow smoother, and improve the dehumidification efficiency.

[0058] In an embodiment not shown in the figure, the ventilation hole 3 may be a circular hole, the aperture of the ventilation hole 3 may specifically be 2 mm, and the diameter of the desiccant is 3 mm, so as to ensure that the desiccant does not leak out from the ventilation hole 3 .

[0059] Specifically in one embodiment, the desiccant is a silica gel desiccant, which is a colorless, transparent, silicon dioxide crystal (also known as silica gel), a chemically inert crystal, the interior of which is an extremely fine pore mesh structure, which can absorb water and retain it through its physical attraction. The silica gel desiccant has a strong moisture absorption capacity and strong adsorption performance, and it will not soften or liquefy even if the silica gel desiccant is completely immersed in water. It has the characteristics of being non-toxic, odorless, non-corrosive, and non-polluting, so it can be in direct contact with any object.

[0060] Specifically in one embodiment, the color-changing desiccant is color-changing silica gel, which gradually changes color after absorbing moisture. The water absorption condition of the dehumidifier desiccant can be obtained by observing the color change of the color-changing silica gel in the display window assembly.

[0061] Specifically in one embodiment, the first color is dark green, and the color change range gradually changes with the water absorption, first turning into light green and then gradually turning into dark green. Therefore, the water absorption of the dehumidifier desiccant can be obtained by observing the color change of the color-changing silica gel in the display window assembly.

[0062] In one embodiment, the display window assembly includes a display window 4 and a cover plate 5, which enclose an installation space. The cover plate 5 is provided with a first ventilation hole 502 connecting the installation space and the installation cavity, and the display window 4 is provided with a second ventilation hole 6 connecting the installation space and the outside world. A color-changing desiccant is provided in the installation space.

[0063] In this embodiment, the display window 4 is provided with a second vent hole 6 connecting the installation space and the outside, and the outside air can enter the installation space through the second vent hole 6 on the display window 4. The cover plate 5 is provided with a first vent hole 502 connecting the installation space and the installation cavity, which can ensure that the water absorption degree of the desiccant in the installation cavity is consistent with the water absorption degree of the color-changing desiccant in the installation space. When the air carrying water vapor enters the installation cavity surrounded by the upper cover 2 and the bottom shell 1, the water vapor in the air will be absorbed by the desiccant, and at the same time, the air carrying water vapor will also enter the installation space, and the color-changing desiccant will absorb the water vapor in the air. When the desiccant is full of water vapor, the color-changing desiccant in the installation space will also be full of water vapor, and the color-changing desiccant in the installation space will turn into the first color. The user can judge the state of the dehumidifier by observing the color displayed on the display window 4.

[0064] Specifically in one embodiment, the display window 4 is made of a transparent material.

[0065] In one embodiment, a plurality of slots 501 are disposed at the edge of the cover plate 5 , and a plurality of buckles 401 are disposed at the display window 4 . The buckles 401 are embedded in the slots 501 and are buckled with the upper cover 2 .

[0066] In this embodiment, the card slot 501 at the edge of the cover plate 5 can assist in positioning the installation of the display window 4, and the buckle 401 on the display window 4 is embedded in the card slot 501 and snap-connected with the upper cover 2. The structure is simple and compact, which facilitates the installation of the display window assembly.

[0067] Specific as Figure 4 As shown, the buckle 401 includes an elastic cantilever 4011 and a locking portion 4012 disposed at the end of the elastic cantilever 4011 , and the width of the locking slot 501 is consistent with the width of the elastic cantilever 4011 .

[0068] Specifically in one embodiment, the upper cover 2 is provided with a latch hole 201 , the cover plate 5 and the display window 4 are located in the latch hole 201 , and the buckle 401 on the display window 4 passes through the latch hole 201 and abuts against the inner surface of the upper cover 2 .

[0069] Specifically in one embodiment, Figure 5 As shown, four slots 501 are provided at the edge of the cover plate 5 , and four buckles 401 are provided at the display window 4 .

[0070] In one embodiment, a heating structure is provided in the installation cavity, and the water vapor absorbed by the color-changing desiccant evaporates due to heat, and the color-changing desiccant changes to a second color.

[0071] In this embodiment, a heating structure is provided in the installation cavity. When the heating structure is working, the desiccant in the installation cavity and the color-changing desiccant in the installation space can be quickly dehydrated, so that the desiccant in the installation cavity and the color-changing desiccant in the installation space can restore the water absorption function. The desiccant and the color-changing desiccant are recycled, and the user does not need to frequently replace the desiccant, thereby improving the practicality of the dehumidifier.

[0072] In addition, when the heating structure is working, the heating structure generates heat, which can be used to dry the air and the generated heat can also be used for heating, thereby improving the practicality of the dehumidifier.

[0073] Specifically in one embodiment, the second color is orange, and when the heating structure works to dehydrate the color-changing desiccant, the color-changing desiccant turns orange.

[0074] In one embodiment, the heating structure includes a heat conducting plate 7 and two heating elements 8 fixedly disposed on the heat conducting plate 7 , and the two heating elements 8 are distributed on both sides of the symmetry axis of the heat conducting plate 7 .

[0075] In this embodiment, by setting two heating elements 8, the heating efficiency can be improved. The two heating elements 8 are set on the heat conducting plate 7. The heat generated by the heating elements 8 can be transferred to the heat conducting plate 7. The heat conducting plate 7 has a larger area than the heating elements 8 and can fully contact with the desiccant, so as to quickly dehydrate the desiccant in the installation cavity and the color-changing desiccant in the installation space, so that the desiccant in the installation cavity and the color-changing desiccant in the installation space can restore the water absorption function.

[0076] Specifically in one embodiment, Figure 7 As shown, a through hole 701 is provided at the symmetry axis of the heat conducting plate 7 , and two heating elements 8 are distributed on both sides of the through hole 701 .

[0077] Specifically in one embodiment, the heating element 8 is fixed on the heat conducting plate 7 via a pressing plate 9 .

[0078] Specifically in one embodiment, one side of the pressing plate 9 is hinged to the heat conducting plate 7. After the heating element 8 is placed on the heat conducting plate 7, the pressing plate 9 is rotated so that the pressing plate 9 is buckled on the heating element 8. Then, the other side of the pressing plate 9 is fixed to the heat conducting plate 7 by screws. In this way, the heating element 8 is fixed without damaging the surface of the heating element 8.

[0079] Specifically in one embodiment, the heating element 8 is a PTC heating element.

[0080] In one embodiment, the two heating elements 8 are parallel to each other and staggered.

[0081] In this embodiment, the two heating elements 8 are arranged parallel to each other and staggered. Experimental data show that, compared with a symmetrical arrangement, the parallel and staggered arrangement can shorten the drying time of the desiccant and improve user satisfaction.

[0082] It should be noted that the staggered arrangement specifically refers to the asymmetrical arrangement of the two heating elements 8 .

[0083]

[0084]

[0085] As shown in Table 1, through experimental comparison, the parallel staggered design scheme shortens the average drying time by 6.8 hours compared with the side-by-side symmetrical design scheme.

[0086] In one embodiment, the edge of the heat conducting plate 7 is close to the cavity wall of the installation cavity.

[0087] In this embodiment, the area of ​​the heat conducting plate 7 is as large as possible, thereby increasing the contact area with the desiccant, allowing various parts to be dried simultaneously, improving the drying efficiency, and reducing energy loss.

[0088] Specific as Figure 6 and Figure 7 As shown, one end of the heat conducting plate 7 is provided with a notch to avoid the coupler, and the other end is spaced a certain distance from the hanging structure to avoid interference with the hanging structure. Both sides of the heat conducting plate 7 are as close to the bottom shell 1 as possible.

[0089] Specifically in one embodiment, the heat conducting plate 7 is an aluminum plate.

[0090] In one embodiment, the upper cover 2 and the bottom shell 1 both include an opening area, and the opening area is provided with a ventilation hole 3; the ratio of the area of ​​the opening area of ​​the upper cover 2 to the surface area of ​​the upper cover 2 is A, A ≥ 90%, and / or, the ratio of the area of ​​the opening area of ​​the bottom shell 1 to the outer surface area of ​​the bottom shell 1 is B, B ≥ 90%.

[0091] In this embodiment, the opening area is large and the double-sided moisture absorption allows the water vapor in the air to effectively enter the dehumidifier and fully contact the desiccant to achieve the best moisture absorption effect. In addition, the strength requirements can still be met and the product drop performance requirements can be met.

[0092] Specifically in one embodiment, the upper cover 2 and the bottom shell 1 further include closed areas, and the closed areas respectively surround the outer sides of the opening areas.

[0093] In one embodiment, the dehumidifier also includes a bracket 10, which is hinged to the bottom shell 1. The bracket 10 has a storage position and an expanded position. When the bracket 10 is in the storage position, the bracket 10 is in contact with the bottom shell 1. When the bracket 10 is in the expanded position, the end of the bracket 10 away from the bottom shell 1 is suitable for supporting the surface of an object.

[0094] In this embodiment, by setting the bracket 10, when the dehumidifier is used, the bracket 10 is rotated to the unfolded position. At this time, the bottom shell 1 and the bracket 10 are supported on the surface of the object, and the dehumidifier stands up, which can enable rapid air convection and improve the moisture absorption effect; when the dehumidifier is not needed, the bracket 10 is rotated to the storage position, and the bracket 10 is fitted with the bottom shell 1, thereby reducing the space occupied by the dehumidifier and facilitating storage.

[0095] In one embodiment, Figure 8 As shown, when the bracket 10 is in the unfolded position, the angle between the plane where the top of the bottom shell 1 is located and the horizontal plane is 53°.

[0096] In this embodiment, when the angle between the plane where the top of the bottom shell 1 is located and the horizontal plane is 53°, the center of gravity of the product can be maintained at the midpoint of the two supporting points to achieve effective fixation. In this position, the heat is uniform, which can fully take away the water molecules in the desiccant, while effectively avoiding the ventilation holes 3 from being blocked, thereby achieving a high drying effect.

[0097] Specifically, by performing temperature field simulation analysis at inclination angles of 0°, 53° and 90°, it is found that at 0° and 90°, there is local temperature concentration and overall temperature unevenness. At 53°, the air achieves effective convection and the heat is uniform, which can fully take away the water molecules in the desiccant, while effectively avoiding the ventilation hole 3 from being blocked, thereby achieving a high drying effect.

[0098] In one embodiment, the upper cover 2 or the bottom shell 1 is provided with a hanging structure.

[0099] In this embodiment, the provision of the hanging structure makes it easy to hang up the desiccant for use, thereby reducing the space occupied by the desiccant.

[0100] Specifically in one embodiment, the hanging structure is a hanging rope 11 .

[0101] Specifically in one embodiment, the hanging rope 11 is fixed in the bottom shell 1 and a portion thereof is exposed. When the upper cover 2 is closed on the bottom shell 1 , only a portion of the hanging rope 11 can be seen from the outside.

[0102] In one embodiment, the bottom shell 1 is provided with a power socket 12 and an indicator light 13. The indicator light 13 is located on one side of the power socket 12.
