[0024] Please see Figure 1-6 The technical solution provided by this utility model specifically includes the following embodiments:

[0025] A public utility management publicity device includes two columns 1, a publicity board 2, and a ridge-shaped roof 4. The publicity board 2 is located between the two columns 1, and the ridge-shaped roof 4 is fixedly connected to the top of the two columns 1. Multiple connecting plates 3 are fixedly connected between the columns 1 and the publicity board 2. A dehumidification mechanism 5 is installed above the publicity board 2, and the dehumidification mechanism 5 extends to both sides of the publicity board 2.

[0026] The dehumidification mechanism 5 includes an air pump 501, a condensing mechanism, a drying mechanism, and an air duct assembly. The air pump 501 is fixedly connected to one side of the bulletin board 2, and the condensing mechanism and the drying mechanism are both fixedly connected to the other side of the bulletin board 2. The drying mechanism is located below the condensing mechanism. The bulletin board 2, the air pump 501, the condensing mechanism, and the drying mechanism are interconnected through the air duct assembly.

[0027] The dehumidification mechanism 5 circulates the air in the bulletin board 2 through the air pump 501 and the air duct assembly. During this process, the circulating air is dehumidified twice through the condensation mechanism and the drying mechanism to prevent the bulletin board in the bulletin board 2 from becoming damp and damaged.

[0028] The condensation mechanism includes a housing 507, inside which a partition 508 is fixedly connected. The partition 508 divides the interior of the housing 507 into a hot-end chamber 509 and a cold-end chamber 510 distributed to the left and right. A semiconductor cooler 511 is embedded in the partition 508. The hot end and cold end of the semiconductor cooler 511 are located inside the hot-end chamber 509 and the cold-end chamber 510, respectively. A heat dissipation vent 512 is provided on the rear side of the housing 507, and the heat dissipation vent 512 is connected to the interior of the hot-end chamber 509.

[0029] The semiconductor cooler 511 in the condensation mechanism mainly consists of a semiconductor cooler, a fan for heat dissipation at the hot end, and fins for cooling at the cold end. The semiconductor cooler 511 is a prior art product, so it will not be described in detail here. After the humid air enters the cold end chamber 510 and comes into contact with the fins, it is pre-cooled. The moisture in the air condenses into water droplets and drips down. The humidity of the air after condensation is reduced. At this time, it is discharged and undergoes secondary dehumidification treatment by the drying mechanism.

[0030] The drying mechanism includes a second box 519, which is located below the first box 507. Inside the second box 519, there are vertically distributed air venting plates 520 and filter plates 522. The second box 519 is filled with activated carbon 521, which is located between the air venting plates 520 and the filter plates 522.

[0031] The activated carbon 521 in the drying mechanism can dry and dehumidify the air again. The moisture in the air is re-adsorbed and then returns to the inside of the display board 2. The air vent plate 520 can divert and guide the air entering the box 2 519 to fully contact the activated carbon, which can improve the dehumidification efficiency of the activated carbon in the dehumidification mode and the drying efficiency of the activated carbon in the drying mode. The filter plate 522 can prevent the activated carbon 521 from falling into the air duct 6 523 and air duct 7 524 and clogging it.

[0032] The duct assembly includes duct 1 (502), duct 2 (503), duct 3 (504), duct 4 (513), duct 5 (514), duct 6 (523), and duct 7 (524). Two ducts 3 (504) are provided. Duct 1 (502) and duct 2 (503) are fixedly connected to the air inlet and outlet of the air pump 501, respectively. The end of duct 1 (502) passes through one side of the bulletin board 2 and connects to the interior of the bulletin board 2. Both ducts 3 (504) are fixedly connected to the ends of duct 2 (503). The ends of ducts 3 (504) are fixedly connected to the top of box 1 (507), and the two boxes 1 (507) are respectively connected to the hot end chamber 509 and the cold end chamber. The interior of chamber 510 is interconnected. The fourth air duct 513 and the fifth air duct 514 are fixedly connected between box body 1 507 and box body 2 519. The fourth air duct 513 and the fifth air duct 514 are distributed on the left and right. The fourth air duct 513 and the fifth air duct 514 are respectively connected to the interior of hot end chamber 509 and cold end chamber 510. The sixth air duct 523 and the seventh air duct 524 are distributed on the left and right and fixedly connected to the bottom of box body 2 519. The fourth air duct 513, the fifth air duct 514, the sixth air duct 523 and the seventh air duct 524 are all connected to the interior of box body 2 519. The end of the seventh air duct 524 passes through the other side of the bulletin board 2 and is connected to the interior of the bulletin board 2.

[0033] Solenoid valve 1 505 and solenoid valve 2 506 are respectively installed on the two ducts 3 504, one-way valve 515 is installed on the ducts 4 513 and 514, and solenoid valve 4 525 and solenoid valve 526 are respectively installed on the ducts 6 523 and 7 524.

[0034] By cooperating with the air pump 501, condensation mechanism, drying mechanism, air duct assembly, and corresponding solenoid valves 505, 506, 515, 518, 525, and 526, two working modes can be achieved: dehumidification mode and drying mode (see the working principle section for details). The dehumidification mode can dehumidify the air in the bulletin board 2 to prevent the bulletin board from getting damp and damaged. The drying mode can achieve the function of self-drying and recycling of activated carbon 521.

[0035] A water collection hopper 516 is fixedly connected to the bottom of the first box 507. The water collection hopper 516 is connected to the interior of the cold end chamber 510. A drain pipe 517 is fixedly connected to the bottom of the water collection hopper 516. The drain pipe 517 is located above the second box 519 and extends to the bottom of the second box 519. A solenoid valve 518 is installed on the drain pipe 517.

[0036] The water condensed in the cold end chamber 510 will eventually drip into the water collection hopper 516 for collection. The opening interval and opening duration of the solenoid valve 518 can be set by the controller 8. When the solenoid valve 518 is opened, the condensate collected in the water collection hopper 516 can be discharged through the drain pipe 517.

[0037] Two front-to-back shielding plates 6 are connected between the column 1 and the bulletin board 2. Two vertically distributed hooks 61 are fixedly connected to the inner side of the shielding plate 6. The hooks 61 are hung on the connecting plate 3. The connecting plate 3 is located between two adjacent front-to-back shielding plates 6. One of the shielding plates 6 has a ventilation opening 7, which is located directly behind the heat dissipation vent 512.

[0038] The baffle 6 is connected to the connecting plate 3 by hook 61. The baffle 6 can cover the various components in the dehumidification mechanism 5, which can improve the aesthetics and prevent passers-by from touching it. The ventilation opening 7 on the baffle 6 located at the rear of the box 507 can cooperate with the heat dissipation opening 512 to dissipate the heat from the hot end of the semiconductor cooler 511 in the hot end chamber 509.

[0039] On the other side of the bulletin board 2, a controller 8 is installed. The air pump 501, semiconductor cooler 511, solenoid valve 1 505, solenoid valve 2 506, solenoid valve 3 518, solenoid valve 4 525 and solenoid valve 526 in the dehumidification mechanism 5 are all electrically connected to the controller 8 and are controlled by the controller 8. These electrical devices are all powered by external lines, and the power supply method is relatively conventional, so it will not be described in detail here.

[0040] Working principle:

[0041] There are two working modes to meet different needs: dehumidification mode and drying mode.

[0042] Dehumidification mode: At this time, solenoid valves 1-505, 3-518, and 5-526 are closed, while solenoid valves 2-506 and 4-525 are open. During use, the air pump 501 and duct 1-502 extract the humid air from the bulletin board 2. Then, through duct 2-503 and duct 3-504, the humid air is guided to the condensation mechanism and enters the cold end chamber 510. When the humid air enters the cold end chamber 510, it encounters the fins of the cold end of the semiconductor cooler 511, and the moisture in the humid air is condensed into water droplets. The air after condensation and dehumidification enters the box 2 519 through duct 5-514 and is dried again by activated carbon 521. Finally, the dried air returns to the bulletin board 2 through duct 7-524 to achieve the purpose of dehumidifying the air in the bulletin board 2 and preventing the bulletin board from getting damp and damaged.

[0043] Drying mode: At this time, solenoid valves 2 (506), 3 (518), and 4 (525) are closed, while solenoid valves 1 (505) and 5 (526) are open. During use, air pump 501 and air duct 1 (502) draw air out of the bulletin board 2, and then guide the air to the condensing mechanism and into the hot end chamber 509 through air ducts 2 (503) and 3 (504). After entering the hot end chamber 509, in addition to some air being discharged from the heat dissipation port 512, the hot air in the heat dissipation port 512 is also blown into the box 2 (519) through air duct 4 (513). After entering the box 2 (519), the hot air can dry and remove the moisture adsorbed in the activated carbon 521 and discharge it through air duct 6 (523), so as to achieve the purpose of self-drying and recycling of activated carbon 521.
