[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar parts or parts having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1-Figure 6 As shown, an embodiment of the present invention provides an air conditioning device, which includes a shell 1, an air intake component 2, an exhaust component 3 and a drying component 4. The shell 1 has a accommodating chamber 11 inside, and the shell 1 is provided with an inlet and an outlet connected to the accommodating chamber 11; the air intake component 2 is arranged outside the shell 1 and connected to the inlet, and the exhaust component 3 is arranged outside the shell 1 and connected to the outlet. The drying component 4 is arranged in the accommodating chamber 11, and the drying component 4 includes a drying sheet 41 wound in a roll shape, and the rolled drying sheet 41 is a multi-layer structure, and the core position of the drying sheet 41 forms an air intake channel, and the drying sheet 41 has a tightened state (there is no gap between the drying sheets 41 of the multi-layer structure) and a loose state (there is a gap between the drying sheets 41 of the multi-layer structure).

[0046] When the air conditioning device is working (i.e., dehumidifying the air), the drying sheet 41 is in a tightened state, and the air enters the air intake channel through the first air intake port of the air intake component 2, and then passes through the multi-layer structure of the drying sheet 41 and is discharged through the first exhaust port of the exhaust component 3. When the air passes through the drying sheet 41, the drying sheet 41 can absorb the moisture of the air so that dry air is discharged.

[0047] When the drying component 4 is drying and recovering, the drying sheet 41 is in a loose state, and the drying gas enters the accommodating chamber 11 through the second air inlet port of the air inlet component 2, and enters the drying sheet 41 through the gaps between the drying sheets 41 of the multi-layer structure, ensuring that the drying gas is in full contact with the drying sheet 41. The drying gas is then discharged through the second exhaust port of the exhaust component 3. After the drying gas enters the drying sheet 41 and is discharged through the second exhaust port, the moisture of the drying sheet 41 can be taken away, so that the drying sheet 41 can be dried and recovered.

[0048] The air conditioning device switches the drying sheet 41 between a tightened state and a loose state to enable the drying component 4 to dehumidify and dry the air, and to achieve drying recovery of the drying component 4, thereby effectively improving the dehumidification and drying effect, and the drying recovery efficiency.

[0049] In this embodiment, when the air conditioning device is installed in the underground space, the first air inlet port of the air inlet component 2 is connected to the underground space, and the second air inlet port of the air inlet component 2 is connected to a drying device that can generate dry gas, which can be a hot air blower; the first exhaust port of the exhaust component 3 is connected to the underground space, and the second exhaust port of the exhaust component 3 is connected to the aboveground space. When it is necessary to dehumidify the air in the underground space, the first air inlet port is in an open state, the second air inlet port is in a closed state, the first exhaust port is in an open state, the second exhaust port is in a closed state, the air enters the air inlet channel through the first air inlet port, and is discharged through the first exhaust port after passing through the drying sheet 41 and flows back to the underground space, so as to achieve dehumidification and regulation of the air in the underground space; when it is necessary to dry and restore the drying component 4, the second air inlet port is in an open state, the first air inlet port is in a closed state, the second exhaust port is in an open state, the first exhaust port is in a closed state, the drying device is turned on and the dry gas is blown into the accommodating cavity 11 through the second air inlet port, and the dry gas is taken away by the drying sheet 41 and then discharged to the aboveground space through the second exhaust port, so as to achieve dry restoration of the drying component 4.

[0050] It is understandable that in order to achieve rapid air flow, such as Figure 2 As shown, the air conditioning device further comprises an air pump 5, which can be arranged outside the housing 1 and communicated with the inlet.

[0051] Optionally, the air intake assembly 2 includes a first air intake pipe 21 and a second air intake pipe 22 connected to the first air intake pipe 21, the first air intake pipe 21 is connected to the inlet, the air pump 5 can be arranged in the first air intake pipe 21 and connected to the inlet, the outer end of the first air intake pipe 21 is a first air intake port, the first air intake pipe 21 is provided with a first valve 211, and the first valve 211 is used to open or close the first air intake port; the outer end of the second air intake pipe 22 is a second air intake port, the second air intake pipe 22 is provided with a second valve 221, and the second valve 221 is used to open or close the second air intake port. The structure is simple in design and easy to operate.

[0052] Optionally, the exhaust assembly 3 includes a first exhaust pipe 31 and a second exhaust pipe 32 connected to the first exhaust pipe 31, the first exhaust pipe 31 is connected to the outlet, the outer end of the first exhaust pipe 31 is a first exhaust port, the first exhaust pipe 31 is provided with a third valve 311, and the third valve 311 is used to open or close the first exhaust port; the outer end of the second exhaust pipe 32 is a second exhaust port, the second exhaust pipe 32 is provided with a fourth valve 321, and the fourth valve 321 is used to open or close the second exhaust port. The structure is simple in design and easy to operate.

[0053] Optionally, the drying assembly 4 further includes a telescopic tube 42 and a sealing plug 43. The telescopic tube 42 is disposed in the accommodating chamber 11, and one end of the telescopic tube 42 is connected to the inlet, that is, the air or dry gas is output through the telescopic tube 42 after passing through the inlet; the sealing plug 43 is sleeved on the outer wall of the other end of the telescopic tube 42. When the air conditioning device is working, the drying sheet 41 is in a tightened state, the other end of the telescopic tube 42 can be extended and extended into the air inlet channel, and the sealing plug 43 can abut against the drying sheet 41 and close the air inlet channel, so as to prevent the air from being output into the air inlet channel through the telescopic tube 42 and then entering the accommodating chamber 11 through the gap between the telescopic tube 42 and the air inlet channel, thereby reducing the air dehumidification effect. When the drying component 4 is dried and restored, the drying sheet 41 is in a loose state, the other end of the telescopic tube 42 is retracted to the outside of the air inlet passage, and the sealing plug 43 is separated from the drying sheet 41. By separating the sealing plug 43 from the drying sheet 41, it is possible to prevent the sealing plug 43 from affecting the switching of the tightened state and the loose state of the drying sheet 41, and the other end of the telescopic tube 42 is retracted to the outside of the air inlet passage. The dry air enters the accommodating chamber 11 through the dry gas transported by the telescopic tube 42, and then enters the gaps between the drying sheets 41 of the multi-layer structure. By retracting the telescopic tube 42, it is convenient for the dry gas to enter the gaps of the drying sheets 41, so that the drying recovery efficiency of the drying sheets 41 is higher.

[0054] Furthermore, the drying sheet 41 is arranged in a roll shape in the accommodating cavity 11, and one end of the drying sheet 41 away from the sealing plug 43 abuts against the inner wall of the accommodating cavity 11 to close the end of the air inlet passage away from the sealing plug 43. This structure prevents air from flowing out without passing through the drying sheet 41.

[0055] Specifically, the drying component 4 also includes a telescopic driving member 44, which is arranged in the accommodating chamber 11, and the fixed end of the telescopic driving member 44 is fixedly connected to the inner wall of the accommodating chamber 11, and the output end of the telescopic driving member 44 is fixedly connected to the sealing plug 43. The telescopic driving member 44 can drive the sealing plug 43 to approach or move away from the drying sheet 41, so that the sealing plug 43 can abut against the drying sheet 41, or be separated from the drying sheet 41; and the sealing plug 43 can drive the telescopic tube 42 to extend or contract when moving.

[0056] Optionally, the telescopic driving member 44 may be an electric telescopic rod. In order to stabilize the structure, the telescopic driving member 44 may include at least two electric telescopic rods.

[0057] Optionally, the drying assembly 4 further includes a driving component, which is used to switch the drying sheet 41 between a tightened state and a loosened state, so that the switching of the drying sheet 41 is more convenient.

[0058] Furthermore, if Figure 3-Figure 6 As shown, the driving component includes a driving motor 45 and a spring sheet 46 wound in a coiled shape, the spring sheet 46 is fixed to the inner surface or outer surface of the drying sheet 41 (may be glued), and the driving motor 45 can drive the spring sheet 46 to roll or unroll, so as to drive the drying sheet 41 to roll or unroll, so as to switch between the rolled state and the loose state. By providing the spring sheet 46, the spring sheet 46 can support the drying sheet 41, so that the rolling and unrolling of the drying sheet 41 are smoother.

[0059] Optionally, a plurality of spring sheets 46 may be provided, and the plurality of spring sheets 46 are spaced apart along the extending direction of the air inlet passage, so as to provide more stable support for the drying sheet 41 .

[0060] In order to facilitate the driving motor 45 to drive the spring sheet 46 to reel in and out, the driving component also includes a connecting rod 47, which is connected to the inner ends of multiple spring sheets 46. The output shaft of the driving motor 45 is provided with a rocker rod 451, which is connected to one end of the connecting rod 47. When the driving motor 45 drives the rocker rod 451 to rotate forward or reverse, it can drive the connecting rod 47 to rotate forward or reverse, thereby driving the spring sheet 46 to reel in or out.

[0061] Furthermore, the driving component also includes a limiting rod 48, which is connected to the outer ends of multiple spring sheets 46. A limiting groove 111 is provided on the inner side wall of the accommodating chamber 11 away from the air intake assembly 2 along its axial direction. The extension direction of the limiting groove 111 is perpendicular to the axial direction of the accommodating chamber 11. One end of the limiting rod 48 is slidably limited in the limiting groove 111. When the spring sheet 46 is wound or unwound, the outer end of the spring sheet 46 moves along the extension direction of the limiting groove 111. By setting the limiting rod 48, the spring sheet 46 can be prevented from position displacement.

[0062] Optionally, the drying sheet 41 may be a sponge sheet or other material having dense pores and capable of absorbing moisture. The sponge sheet may be filled with a desiccant to improve the moisture absorption effect of the drying sheet 41 .

[0063] In this embodiment, the housing 1 is cylindrical, the drying sheet 41 is arranged in a roll in the accommodating chamber 11, the axis of the air inlet passage coincides with the axis of the housing 1, the inlet is arranged on the side wall of the housing 1 along its axis, and the axis of the inlet coincides with the axis of the housing 1, so that the axis of the telescopic tube 42 coincides with the axis of the air inlet passage, and the structural design is reasonable. The outlet is arranged on the outer peripheral wall of the housing 1, so that the air enters the air inlet passage and passes through the drying sheet 41 for discharge.

[0064] Optionally, refer to Figure 1-Figure 2 The housing 1 has two accommodating chambers 11 arranged at intervals along the axial direction of the housing 1. Drying components 4 are arranged in the two accommodating chambers 11, and the inlet and outlet of each accommodating chamber 11 are respectively connected to the first air intake pipe 21 of the air intake component 2 and the first exhaust pipe 31 of the exhaust component 3. The two drying components 4 can work and dry and recover alternately, or the two drying components 4 can work and dry and recover simultaneously. By setting two accommodating chambers 11, the air conditioning efficiency can be effectively improved.

[0065] The portion of the housing 1 between the two accommodating chambers 11 is provided with an installation space, and the two drive motors 45 are symmetrically installed in the installation space, and the output shafts of the two drive motors 45 can extend into the two accommodating chambers 11 respectively.

[0066] In this embodiment, the air conditioning device also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical components used in this solution, including but not limited to the telescopic drive member 44, the drive motor 45, the drying device, the air pump 5, etc.

[0067] The air conditioning device also includes a display screen, through which commands can be input to the air conditioning device, and the display screen can also display the working status of the underground space air conditioning device.
