The air intake pipe 11 is fixedly connected to the side wall of the emergency power supply body 1. The suction hopper 12 is fixedly connected to the end of the air intake pipe 11 away from the emergency power supply body 1. The exhaust fan 13 is installed in the middle of the air intake pipe 11.

The filter bag 14 filters the incoming air, and the filtered air enters the emergency power supply body 1, creating positive pressure inside the emergency power supply body 1. When impurities or foreign objects are adsorbed on the surface of the filter bag 14, the pull ring 16 is pulled, and the pull ring 16 drives the pull rope 15 to pull the filter bag 14 out of the suction hopper 12. Shaking the pull rope 15 and the filter bag 14 shakes off the impurities adsorbed on the surface of the filter bag 14. Through the above structure, the filter bag 14 filters the air entering the emergency power supply body 1, forming an air intake filter structure.

[0027] like Figures 4 to 6As shown, the drying assembly includes a drying box 2, a cover plate 21, and a handle 22. The drying box 2 is detachably installed in the middle of the air inlet pipe 11. The cover plate 21 is detachably installed on the top of the drying box 2. A sealing component is provided at the bottom of the cover plate 21. The handle 22 is fixedly connected to the top of the cover plate 21. An anti-slip component is provided in the middle of the handle 22. During operation, desiccant is placed inside the drying box 2, the drying box 2 is inserted into the middle of the air inlet pipe 11, the cover plate 21 is placed on top of the air inlet pipe 11, and the air blown into the emergency power supply body 1 by the exhaust fan 13 is dried by the desiccant inside the drying box 2, absorbing the moisture in the air and reducing the moisture content of the air entering the emergency power supply body 1. When removing the desiccant, hold handle 22 and pull the desiccant box 2 out from the middle of the air inlet pipe 11 to replace it with a new desiccant assembly. Through the above structure, the desiccant inside the desiccant box 2 dries the air entering the emergency power supply body 1, forming an air drying structure. This achieves the function of drying the air entering the emergency power supply body 1, solving the problem of oxidation and corrosion of the switch contacts inside the emergency power supply body 1 caused by high external air humidity entering the body.

[0028] like Figure 5 and Figure 6 As shown, the locking assembly includes a locking block 3, a sliding block 31, and a spring 32. The locking block 3 is rotatably connected to the side wall of the air inlet pipe 11 near the drying box 2. A pair of locking blocks 3 are provided on the side wall of the air inlet pipe 11 and are symmetrically arranged. The sliding block 31 is slidably connected to the bottom of the locking block 3 near the drying box 2. One end of the spring 32 is fixedly connected to the top of the sliding block 31. Multiple sets of springs 32 are provided on the top of the sliding block 31 and are evenly distributed on the top of the sliding block 31. The other end of the spring 32 is fixedly connected to the inside of the locking block 3. A pair of slots are provided on the cover plate 21 near the top of the sliding block 31. During operation, when the drying box 2 is inserted into the middle of the air inlet pipe 11, the cover plate 21 covers the air inlet pipe 11. At the top, rotating the locking block 3 causes it to lock onto the top of the cover plate 21. The sliding block 31 slides into the slot at the top of the cover plate 21 under the elastic force of the locking block 3. The sliding block 31 is then locked between the locking block 3 and the slot of the cover plate 21, fixing the cover plate 21 to the top of the air inlet pipe 11. This structure, where the sliding block 31 is locked between the locking block 3 and the cover plate 21, forms a locking and fixing structure for the cover plate 21. This achieves the function of fixing the cover plate 21 to the top of the air inlet pipe 11, solving the problem of the cover plate 21 becoming loose at the top of the air inlet pipe 11, reducing the possibility of air leakage due to loosening between the air inlet pipe 11 and the cover plate 21, and improving the stability of the cover plate 21 and the drying box 2 during installation.
[0029] like Figure 2As shown, the air outlet assembly includes a check valve 4. The check valve 4 is installed on the side wall of the emergency power supply body 1 away from the air inlet pipe 11. During operation, the check valve 4 has a one-way ventilation structure. After positive pressure is formed inside the emergency power supply body 1, when the air pressure is greater than the preset pressure of the check valve 4, the check valve 4 is opened and air is discharged from the check valve 4. When the air pressure is less than the preset pressure of the check valve 4, the check valve 4 is closed. Through the above structure, the one-way ventilation setting of the check valve 4 forms a one-way air outlet structure of the device, which improves the sealing of the device and reduces the possibility of external air or impurities entering the interior of the emergency power supply body 1.
[0030] like Figure 5 As shown, the anti-slip component includes a silicone strip 5; the silicone strip 5 is fixedly connected to the middle of the handle 22; during operation, when the handle 22 is gripped, the hand comes into contact with the silicone strip 5, increasing the friction between the hand and the handle 22; through the above structure, the silicone strip 5 comes into contact with the hand to increase the friction, forming an anti-slip structure for the handle 22, increasing the friction between the hand and the handle 22 when the handle 22 is pulled, and reducing the slippage that occurs when the handle 22 is pulled.
[0031] like Figure 6 As shown, the sealing assembly includes a sealing strip 6; the sealing strip 6 is fixedly connected to the bottom of the cover plate 21; during operation, when the cover plate 21 covers the top of the air inlet pipe 11, the sealing strip 6 seals the space between the cover plate 21 and the air inlet pipe 11, reducing the leakage of air between the cover plate 21 and the air inlet pipe 11, improving the sealing performance of the device, and reducing the entry of external air that has not been dried into the interior of the emergency power supply body 1.
[0032] During operation, when using the emergency power supply unit 1, the desiccant is placed inside the drying assembly, which is then installed in the middle of the air intake assembly and secured with the locking assembly. The air intake filter assembly filters outside air and draws it into the emergency power supply unit 1. As air enters the unit, the drying assembly dries it, maintaining a positive pressure inside the unit. Air is then exhausted from the gaps or exhaust assembly, keeping the interior of the unit dry. The exhaust fan 13 is then activated, drawing outside air into the unit. When the air is inside the emergency power supply body 1, the filter bag 14 is tightly attached to the suction duct 12 and the baffle 17. The filter bag 14 filters the incoming air, and the filtered air enters the emergency power supply body 1, creating positive pressure inside the emergency power supply body 1. When impurities or foreign objects are adsorbed on the surface of the filter bag 14, pull the pull ring 16. The pull ring 16 drives the pull rope 15 to pull the filter bag 14 out of the suction duct 12. Shake the pull rope 15 and the filter bag 14 to shake off the impurities adsorbed on the surface of the filter bag 14. Put the desiccant into the drying box 2, insert the drying box 2 into the middle of the air inlet pipe 11, cover the top of the air inlet pipe 11 with the cover plate 21, and blow the exhaust fan 13 towards the emergency power supply body 1. The air inside the power supply unit 1 is dried by the desiccant inside the drying box 2, which absorbs moisture from the air, reducing the moisture content of the air entering the emergency power supply unit 1. When replacing the desiccant, hold the handle 22 and pull the drying box 2 out from the middle of the air inlet pipe 11 to replace it with a new drying component. When the drying box 2 is inserted into the middle of the air inlet pipe 11, the cover plate 21 covers the top of the air inlet pipe 11. Rotate the locking block 3, and the locking block 3 locks into the top of the cover plate 21. The sliding block 31 slides into the slot on the top of the cover plate 21 under the elastic force of the locking block 3. The sliding block 31 is locked between the locking block 3 and the slot of the cover plate 21, fixing the cover plate 21 to the top of the air inlet pipe 11. Check valve 4 is a one-way ventilation structure. After positive pressure is formed inside the emergency power supply body 1, the air pressure is greater than the preset pressure of the check valve 4, the check valve 4 is opened, and air is discharged from the check valve 4. After the air pressure is less than the preset pressure of the check valve 4, the check valve 4 is closed. When the handle 22 is held, the hand comes into contact with the silicone strip 5, increasing the friction between the hand and the handle 22. When the cover plate 21 is placed on top of the air inlet pipe 11, the sealing strip 6 seals the cover plate 21 and the air inlet pipe 11, reducing the leakage of air between the cover plate 21 and the air inlet pipe 11, improving the sealing performance of the device, and reducing the entry of external air that has not been dried into the interior of the emergency power supply body 1.
