[0024] Specific improvement, the side of the front shell 2 is provided with the moisture discharge port 23 distributed upward and downward, and the side of the front shell 2 is provided with the heat dissipation hole 22 distributed in the middle; The moisture discharge port 23 is used to discharge moisture in a large diameter, and the heat dissipation hole 22 is used for high-efficiency heat dissipation.

[0025] The overall function of the dehumidification device is to adsorb the moisture in the moisture-proof box and discharge it outside the box, thereby reducing the humidity.

[0026] Working state: the humidity in the moisture-proof box is greater than the preset humidity, the dehumidification device starts to work to reduce the humidity; when the humidity is reduced to the set humidity, the dehumidification device stops working and enters the standby state; The humidity in the moisture-proof box is less than the preset humidity, the humidifier starts to work to increase the humidity; when the humidity rises to the set humidity, the humidifier stops working and enters the standby state, and the dehumidification core 14 power supply is required.

[0027] The dehumidification device is installed on one side of the sealed moisture-proof box, one side with the moisture suction port 12 faces inwards, and the other side with the moisture discharge port 23 faces outwards.

[0028] The molecular sieve desiccator 28 is made of molecular sieve particles, has a large specific surface area, and the specific surface area of each gram of the molecular sieve can reach 800-1000 square meters; the huge specific surface area and uniform microporous structure endow the molecular sieve with strong and efficient adsorption capacity, so that the molecular sieve can quickly and massively adsorb small molecules such as water vapor; at the same time, the molecular sieve has strong affinity for water molecules and can maintain good adsorption performance in an environment with low relative humidity.

[0029] With the continuous progress of the adsorption process, the micropores in the molecular sieve are gradually filled with water molecules, and when the saturation state is reached, the molecular sieve loses the dehumidification capacity, and at this time, the molecular sieve needs to be regenerated to restore the adsorption performance; in the regeneration stage, the control system starts the heating device in the molecular sieve dehumidification module to heat the molecular sieve to a certain temperature, usually 200-240°C; under the action of high temperature, the adsorption force between the molecular sieve and the water molecules is weakened, and the water molecules are desorbed from the micropores to form high-temperature water vapor; the high-temperature water vapor is spontaneously discharged from the exhaust port to the outside of the desiccant box; after a period of regeneration, the molecular sieve returns to the initial state and regains the adsorption capacity, and can be used for dehumidification again.

[0030] When the hinged door 29 faces the moisture absorption port, the exhaust port is closed, and the molecular sieve desiccator 28 adsorbs moisture; when the hinged door 29 faces the exhaust port, the moisture absorption port is closed, and the PTC heating sheet inside the molecular sieve desiccator 28 generates heat to discharge moisture outward, and the heating sheet inside the molecular sieve desiccator 28 is used for heating and baking to regenerate the molecular sieve desiccator 28.

[0031] The memory spring 242 will contract after being heated and will stretch after stopping heating, and the contraction or stretching of the memory spring 242 is controlled by the PTC heating sheet 24, so as to control the switching direction of the hinged door 29.

[0032] The stepping motor 17 rotates to control the extension and contraction of the connecting rod B 174, and when the connecting rod B 174 contracts, the sealing cover 13 of the moisture absorption port 12 is opened; when the connecting rod B 174 extends, the sealing cover 13 of the moisture absorption port 12 is closed.

[0033] The dehumidification cycle is about 3.5 hours, including 3 hours of moisture absorption process and 0.5 hours of moisture discharge process, and if the humidity does not reach the setting, the next cycle will continue; if the humidity reaches the setting, the working cycle will stop and enter the standby state.

[0034] When the humidity sensor senses that the humidity in the humidity-proof box is higher than the preset humidity, the sealing cover 13 of the moisture absorption port 12 is opened, the hinge door 29 is turned to the moisture absorption port 12, the molecular sieve humidity-proof bead filter core 28 absorbs moisture, and after 3 hours, the sealing cover 13 of the moisture absorption port 12 is closed, the hinge door 29 is turned to the moisture discharge port 23, the heating sheet in the molecular sieve humidity-proof bead filter core 28 generates heat for 0.5 hours, the molecular sieve humidity-proof bead filter core 28 releases moisture to the outside of the humidity-proof box after being heated, and the above steps are repeated until the humidity reaches the setting.

[0035] As shown in the working process, when the humidity reaches the preset humidity, the sealing cover 13 of the moisture absorption port 12 is closed, and at this time, the humidity in the humidity-proof box no longer decreases.

[0036] The above shows and describes the basic principles and main features of the present application and the advantages of the present application, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0037] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that those skilled in the art can understand.
