[0029] like Figures 1 to 6As shown, a metering type electric energy meter box includes: a fixed box 1, a drying block 103 is provided inside the fixed box 1, a dustproof net 102 is provided on the outside of the fixed box 1, and the dustproof net 102 is arranged directly below the drying block 103; a ventilation mechanism is arranged inside the fixed box 1, for conducting the air inside the fixed box 1, the ventilation mechanism includes a sealing member 2 and a fixing member 3, the fixing member 3 is arranged inside the fixed box 1, the sealing member 2 is arranged inside the fixed box 1, and the sealing member 2 cooperates with the fixing member 3 to block water; an exhaust member 4 is arranged outside the fixed box 1, for exhausting air. Specifically, when the meter box is in use, First, the meter is installed inside the fixing part 3 to facilitate fixing the meter when in use. During the use of the meter, the cooperation of the sealing part 2 and the fixing part 3 drives the air inside the fixing box 1 to flow, thereby cooling the meter. Finally, the direction of the air flow is guided by the exhaust part 4 to ensure the cooling effect during the use of the meter. An electric energy meter is installed inside the fixing part 3. The electric energy meter counts the amount of electric energy used during use. The meter is existing technology and will not be explained in detail here. The fixing box 1 provides support for the fixing part 3 to avoid damage to the fixing part 3 due to force during use.

[0030] like Figures 1 to 6 As shown, a plurality of ear plates 101 are further provided on the outside of the fixed box 1. Specifically, the ear plates 101 can be connected to the fixed box 1 by welding or threading, so that the position of the fixed box 1 can be fixed by the ear plates 101 during use, ensuring the stability of the position of the fixed box 1 when in use. The dustproof net 102 filters the air entering from the bottom to prevent dust from entering the interior of the fixing part 3. The dustproof net 102 is connected to the fixed box 1 by a magnet or a snap, which is convenient for removing and cleaning the dustproof net 102 when in use. The drying block 103 absorbs the moisture of the air entering from the bottom of the fixed box 1 to prevent moisture from condensing inside the fixed box 1 and causing short circuit damage to the meter.

[0031] like Figures 1 to 6As shown, the sealing member 2 includes a rotating cover 201, which is rotatably connected to the fixed box 1. The rotating cover 201 is provided with a baffle 202 on one side relative to the fixed box 1. An air inlet 204 and an inclined slot 205 are provided inside the rotating cover 201, and the air inlet 204 and the inclined slot 205 pass through the rotating cover 201. There are multiple air inlet holes 204, and multiple filter blocks 203 are provided between the rotating cover 201 and the baffle 202. Specifically, during use, air enters the rotating cover 201 and the baffle 202 through the air inlet holes 204, and then the air enters the fixed box 1 under the guidance of the baffle 202 to cool the meter, thereby ensuring the meter's stability during use. The rotating cover 201 cooperates with the baffle 202 to guide the air while preventing water droplets from directly entering the fixed box 1 with the air. The baffle 202 cooperates with the inclined slot 205 to divert and discharge the blocked water, thereby preventing the blocked water from The filter block 203 is stacked between the filter block 203 and the rotating cover 201, and the drying block 103 and the filter block 203 are filled with desiccant. There is no restriction on the material of the desiccant, and it can be a silica gel desiccant, a mineral desiccant, a molecular sieve desiccant, or other materials that absorb moisture in the air, so that it can absorb moisture in the air during use to ensure that the air entering the fixed box 1 is dry. The filter block 203 can be replaced according to the usage to ensure the water absorption effect of the desiccant. The rotating cover 201 is rotatably connected to the fixed box 1, which is convenient for maintenance and replacement of the meter during use. An observation window is also provided inside the rotating cover 201, through which the data of the meter can be intuitively viewed. A sealing strip is provided between the rotating cover 201 and the fixed box 1 to prevent water from seeping into the fixed box 1 through the gap between the rotating cover 201 and the fixed box 1 during use, thereby ensuring the sealing effect during use.

[0032] like Figures 1 to 6As shown, the fixing member 3 includes a connecting shell 301, which is arranged inside the fixing box 1, and a cavity 302 is opened inside the connecting shell 301. A connecting hole 303 is opened on the outside of the connecting shell 301, and the connecting hole 303 is connected to the cavity 302, and the connecting hole 303 is located directly above the drying block 103. A plurality of partitions 304 are provided inside the cavity 302, and a plurality of air guide holes are opened on the inner wall of the connecting shell 301. Specifically, during use, the connecting shell 301 cooperates with the cavity 302 to guide the air entering from the drying block 103, and at the same time, the air inside the cavity 302 is uniformly guided through the partition 304, so that the air flows evenly inside the cavity 302. At the same time, the connecting pipe 305 cooperates with the air inlet hole 204 to enter the fixed box 1. The air is sucked into the cavity 302, thereby cooling the meter. During use, the air is first driven to flow inside the cavity 302 through the exhaust member 4. Since the cavity 302 is connected to the fixed box 1 through the air guide hole, the air entering the fixed box 1 through the air inlet hole 204 is sucked into the cavity 302 through the air guide hole during the air flow inside the cavity 302, thereby cooling the meter. The cooperation of the baffle 202 and the connecting shell 301 can block the inhaled water droplets from the meter during use, while cooling the meter, to avoid short circuit caused by contact between water and the meter. Multiple air guide holes cooperate with the partition 304 to evenly suck the air inside the fixed box 1 into the cavity 302, to avoid dead corners of air flow inside the fixed box 1.

There are multiple mounting brackets 306 and connecting pipes 305, and the connecting pipes 305 correspond one-to-one to the air guide holes, and the connecting pipes 305 are connected to the partition 304. Specifically, the connecting pipe 305 is inclined, and the air inlet end of the connecting pipe 305 is opposite to the direction of air flow inside the cavity 302, so as to avoid the air from entering the fixed box 1 through the connecting pipe 305 during the flow process, causing air turbulence inside the fixed box 1. The mounting bracket 306 provides support for the meter to ensure that the position of the meter is stable during installation.

[0034] like Figures 1 to 6As shown, the exhaust member 4 includes a fixed block 401, which is arranged at the end of the fixed box 1, and a connecting groove 402 and a communicating groove 404 are respectively opened inside the fixed block 401, and the connecting groove 402 and the communicating groove 404 are connected, the connecting groove 402 is connected to the cavity 302, and a fan 403 is provided inside the communicating groove 404, and a fixed cover 405 is provided on the outside of the fixed block 401. Specifically, when in use, the air is controlled to flow inside the cavity 302 by the cooperation of the fan 403, the connecting groove 402 and the communicating groove 404. At the same time, the fixed cover 405 is cooperated to control the flow direction of the air to avoid the inhalation of water vapor when the air flows in the opposite direction. The fan 403 can drive the air to flow. The fan 403 is a prior art and will not be explained in detail here. The fan 403 cooperates with the communicating groove 404 to guide the air inside the cavity 302 so that the air can be discharged. The fixed cover 405 is a one-way valve to prevent external air from entering the fixed box 1 when it is not in use.
