[0041] like Figures 1 to 12 As shown, an embodiment of the present invention provides a dehumidification device, which includes a shell 10 and a dehumidification component 20.

[0042] The dehumidification device provided in this embodiment includes a shell 10 and a dehumidification component 20. The shell 10 has a dehumidification chamber 11, and is provided with a gas inlet 12 and a gas outlet 13 connected to the dehumidification chamber 11. The gas inlet 12 and the gas outlet 13 can be opened and closed, so that the gas in the distribution box is passed into the dehumidification chamber 11 through the gas inlet 12, and the dehumidification component 20 in the dehumidification chamber 11 is used to dehumidify the gas, so as to avoid condensation in the distribution box due to heavy moisture in the gas, thereby affecting the insulation of the equipment. Among them, the dehumidification component 20 includes a first cylinder 21, a second cylinder 22 and a dehumidification filler. The first cylinder 21 is located in the second cylinder 22. A gas channel is arranged between the first cylinder 21 and the second cylinder 22. A first flow hole 211 is arranged on the first cylinder 21. The first flow hole 211 is respectively connected to the gas inlet 12 and the gas channel, so that the gas in the first cylinder 21 can enter the gas channel through the first flow hole 211, and the dehumidification seasoning in the gas channel is used to dehumidify the moisture in the air. The gas channel is connected to the gas outlet 13, so that the air after dehumidification in the gas channel can be discharged through the gas outlet 13, which can improve the dehumidification capacity in the distribution box, avoid the heavy humidity in the distribution box in rainy weather, cause condensation in the distribution box, affect the insulation of the equipment, and ensure the normal operation of the distribution box.

[0043] like Figures 6 to 8As shown, the dehumidification component 20 also includes an air guide column 23, an air guide cover 24, a first partition protrusion 25 and a second partition protrusion 26. The air guide column 23 is arranged in the first cylinder 21, and the air guide cover 24 is sleeved on the outside of the second cylinder 22. A second flow hole 221 is arranged on the second cylinder 22, and the gas channel is connected with the second flow hole 221. The first partition protrusion 25 is arranged on the air guide column 23. The first partition protrusion 25 divides the space between the inner wall of the first cylinder 21 and the air guide column 23 into a plurality of first air guide cavities 31. The second partition protrusion 26 is arranged on the inner wall of the air guide cover 24. The second partition protrusion 26 divides the space between the outer wall of the second cylinder 22 and the air guide cover 24 into a plurality of second air guide cavities 32. The first partition protrusion 25 and the second partition protrusion 26 are vertically staggered, and the gas channel is respectively connected with the first air guide cavity 31 and the second air guide cavity 32. With the above structure, by setting the air guide column 23 in the first cylinder 21, the air guide cover 24 is sleeved on the outside of the second cylinder 22, and a second flow hole 221 is set on the second cylinder 22, so that the gas entering the gas inlet can enter the gas channel through the first flow hole 211, and the gas channel is connected with the second flow hole 221, so that the gas can enter between the air guide cover 24 and the second cylinder 22, wherein a first partition protrusion 25 is set on the air guide column 23, the first partition protrusion 25 divides the space between the inner side wall of the first cylinder 21 and the air guide column 23 into a plurality of first air guide chambers 31, and a second partition protrusion 26 is set on the inner side wall of the air guide cover 24, and the second partition protrusion 26 divides the space between the outer side wall of the second cylinder 22 and the air guide cover 24 into a plurality of second air guide chambers 32, and the first partition protrusion 25 and the second The partition protrusions 26 are arranged in an alternating manner along the vertical direction, so that the gas can first enter the first air guide chamber 31 through the gas inlet, and the gas in the first air guide chamber 31 enters the gas channel through the first flow hole 211, and the moisture in the gas is dehumidified by the dehumidification filler in the gas channel, and the gas in the gas channel enters the second air guide chamber 32 through the second flow hole 221, and then the gas flowing in the second air guide chamber 32 enters the gas channel again through the second flow hole 221, and then the gas in the gas channel enters another first air guide chamber 31 through the first flow hole 211, and then continues to enter another second air guide chamber 32 through the first flow hole 211, the gas channel and the second flow hole 221, so that the dehumidification effect of the dehumidification filler in the gas channel on the gas can be enhanced, so as to ensure that the gas is completely dehumidified and avoid condensation of the gas in the equipment.

[0044] It should be noted that, since the first partition protrusion 25 and the second partition protrusion 26 are arranged at a vertical interval, it means that when the gas enters the gas channel through the first flow hole 211 and enters the second air guide chamber 32 to flow, when the gas enters the gas channel from the second air guide chamber 32 through the second flow hole 221, the gas channel then enters the first air guide chamber 31, so that the gas, under the action of the first flow hole 211, the gas channel and the second flow hole 221, realizes the gas in the first air guide chamber 31, the gas channel and the second air guide chamber 32 to flow alternately, so that the gas flows upward from the bottom of the dehumidification chamber 11, and the gas enters the gas channel in the first air guide chamber 31. The gas enters the second air guide cavity 32 through the gas channel, and the gas in the second air guide cavity 32 enters the gas channel again. At this time, the gas gradually flows upward in the dehumidification cavity 11, thereby ensuring that the dehumidification filler in the dehumidification cavity 11 can dehumidify the gas, so that the gas needs to enter the gas channel when entering the second air guide cavity 32 from the first air guide cavity 31, and the gas also needs to enter the gas channel when entering the first air guide cavity 31 from the second air guide cavity 32, so that the dehumidification filler filled vertically in the gas channel can dehumidify the gas, so that it can be ensured that the dehumidification filler filled vertically along the gas channel can dehumidify the moisture of the gas, and ensure the dehumidification effect. Specifically, guided by the first air guide cavity 31 and the second air guide cavity 32, the gas channel of the dehumidification component 20 shuttles in a wave shape to fully dry the moisture, so as to achieve the purpose of fully drying the moisture in an environment where the humidity rises rapidly.

[0045] like Figure 7 As shown, the first partition protrusion 25 is connected to the inner wall of the first cylinder 21, the upper surface and the lower surface of the first partition protrusion 25 are both arc-shaped surfaces, and the upper surface and the lower surface of the second partition protrusion 26 are both arc-shaped surfaces. By adopting the above structure, the upper surface and the lower surface of the first dividing protrusion 25 are both arc-shaped surfaces, and the upper surface and the lower surface of the second dividing protrusion 26 are both arc-shaped surfaces, so that the surface where the gas flows through the first air guide chamber 31 can be an arc-shaped surface, so that the surface where the gas flows is an arc-shaped structure, avoiding the angular structure that causes condensation of gas in the first air guide chamber 31 and the second air guide chamber 32, ensuring smoother gas circulation, and setting the arc-shaped surface can better guide the gas from the first air guide chamber 31 through the first flow hole 211 into the gas channel, and the gas channel then enters the second air guide chamber 32 through the second flow hole 221, and the second air guide chamber 32 is under the action of the second dividing protrusion 26. Smooth gas circulation is ensured, and then under the action of the arc-shaped surface, condensation can be avoided and a part of the guiding effect on the flow of gas can be played.

[0046] like Figures 1 to 5As shown, the housing 10 includes a first shell 14, a second shell 15 and a third shell 16. The first shell 14 has a discharge chamber 141 for storing dehumidification fillers. The dehumidification chamber 11 is arranged in the second shell 15. The third shell 16 has a discharge chamber 161 to discharge the dehumidification fillers into the discharge chamber 161. The discharge chamber 141 is connected to the top of the gas channel through the first discharge port 33. The bottom of the gas channel is connected to the discharge chamber 161 through the second discharge port 34. The gas inlet 12 and the gas outlet 13 are both arranged in the second shell 15. With the above structure, by arranging the discharge chamber 141 on the first shell 14, the discharge chamber 141 can play a role in storing the dehumidification fillers. The dehumidification chamber 11 is arranged in the second shell 15. The discharge chamber 161 is arranged in the third shell 16, so that the dehumidification fillers in the dehumidification chamber 11 of the second shell 15 can be discharged into the discharge chamber 161 for discharge. Specifically, the discharge chamber 141 is connected to the top of the gas channel through the first discharge port 33, so that the dehumidification filler in the discharge chamber 141 can enter the gas channel, and the bottom of the gas channel is connected to the discharge chamber 161 through the second discharge port 34, so that the dehumidification filler in the dehumidification chamber 11 can be discharged into the discharge chamber 161 through the second discharge port 34. This makes it easy to replace the dehumidification filler in the gas channel, and ensures that the dehumidification filler in the gas channel can always have a dehumidification effect on the gas in the dehumidification chamber 11, thereby avoiding the long dehumidification time of the dehumidification filler affecting the dehumidification effect of the dehumidification component 20.

Since the discharge port is connected to the second discharge port 34, it is convenient to discharge the dehumidification filler in the gas channel into the discharge chamber 161 through the discharge port and the second discharge port 34, so that the discharge chamber 141 discharges the dehumidification filler into the gas channel, and the dehumidification filler in the gas channel is discharged into the discharge chamber 161. In this way, the dehumidification filler in the gas channel can be replaced to ensure the dehumidification effect of the dehumidification filler.
