DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 To be continued Figure 5 As shown, the modular moisture-proof power box provided by the embodiment of this utility model is used for modular moisture-proof treatment of the internal structural components of the power box. It can both ventilate and prevent moisture, and also seal the closed power box to prevent the ingress of external water, thus achieving modular moisture-proofing of the power box. Currently, existing power boxes include a power control terminal 1 and a box body 11 connected through each other. A ventilation opening 12 is provided on the rear side of the box body 11. Moisture-proofing of the internal structural components of the power box is achieved by utilizing the airflow between the power box and the outside air. A condensation dehumidification component 2 is provided on the upper side of the inside of the box body 11, and a bottom cover 31 is provided at the bottom of the box body 11 to cooperate with the condensation dehumidification component 2. The bottom cover 31 can be snapped onto the box body 11, increasing the detachability between the bottom cover 31 and the box body 11, serving as the mounting end for the internal structural components of the power box, facilitating the use of the power box. Next, a magnetic closing component 32 is installed on the bottom cover 31. By using the magnetic closing component 32 to magnetically open and close the bottom cover 31, a magnetic ventilation structure at the bottom of the power box can be added for the discharge of condensed water inside the power box and for sealing the power box when it is powered off. When the power box is in use, it can be opened through the bottom cover 31 to load the required components, and then the area can be sealed to complete the sealing of the power box. When the power box is in use and the power is applied, the magnetic closing component 32 can be used to open the bottom cover 31 to allow external and internal air to circulate for dehumidification. When there is a lot of water vapor in the circulating air, the condensation dehumidification component 2 can be used to condense the water vapor into liquid, which is then discharged through the open bottom cover 31 to increase the dryness inside the power box. When the power box is powered off and closed, the magnetic closing component 32 can close the vent on the bottom cover 31 to seal the power box, achieving dehumidification and drying of the power box under different conditions, improving the operating environment of the components inside the power box, and extending the service life of the power box.

[0027] Next, the switch of the vent 12 on the existing box 11 is set to be one-way. A one-way ventilation component 4 can be installed on the box 11 at the vent 12, so that the gas at the vent 12 can only go out and not enter through the one-way ventilation component, which makes it easy to close and seal the vent 12 after the power box is turned off, complete the moisture prevention at the vent, and solve the dehumidification problem when the existing power box is turned off and stationary.

[0028] It is worth noting that the condensation dehumidification component 2 can use the horizontal end 21 fixed on the box body 11 and the condensation plate 22 set at the lower end of one side of the horizontal end 21 to dehumidify and dry the inside of the power box. Then, a collecting strip 23 is set at the bottom of the condensation plate 22 and extends into the bottom cover 31. When the condensation dehumidification component 2 is used, the water vapor in the power box first comes into contact with the condensation plate 22. After being cooled by the condensation plate 22, it can condense into liquid water. Then, due to the downward tilt of the condensation plate 22 in the power box, the liquid water slides to the lower end of the condensation plate 22 under the influence of gravity. Then, the liquid water is absorbed by the collecting strip 23 set at the bottom of the condensation plate 22 and is transferred into the bottom cover 31. In order to facilitate the use of the power box and the continuous condensation dehumidification in the off state, a water-absorbing structure made of desiccant can be covered in the bottom cover 31 to realize the transfer of condensed water, increase the dryness inside the power box, and perform modular dehumidification for the inside of the power box.

[0029] In some embodiments, the condensation plate 22 can be made of heat-dissipating metal material, and the collecting strip 23 can be made of absorbent cotton material to improve the condensation rate of water vapor on the condensation plate 22 and facilitate the transfer of condensed water. In order to quickly transfer liquid water, the condensation plate 22 is inclined on the horizontal end 21, and the lower end of the condensation plate 22 is set close to the vent 12, so that the condensed liquid water can quickly slide to the collecting strip 23 and turn out by gravity, thereby improving the transfer rate of liquid water and increasing the dryness of the power supply box.

[0030] When using the power supply box, a first air vent 311 can be opened at the bottom cover 31. When the power supply box is powered off, the first air vent 311 can be sealed using the magnetic closure assembly 32. Figure 3 and 4 As shown, in some embodiments, the magnetic closing assembly 32 includes a slide rail 321 fixed on the bottom cover 31, and a baffle plate 33 is slidably mounted on the slide rail 321. The baffle plate 33 can be made of magnetic metal material. The first air vent 311 can be magnetically opened and closed by an electromagnetic plate 34 and a magnetic plate 341 respectively provided at both ends of the slide rail 321. The electromagnetic plate 34 uses an existing electromagnet structure and is connected to the power supply in the power supply box. When the power supply box is powered on, part of the power can be supplied to the electromagnetic plate 34 to make it magnetic. Furthermore, the electromagnetic conductivity of the electromagnetic plate 34 is greater than that of the magnetic plate 341. Therefore, when the electromagnetic plate 34 is energized, the shielding plate 33 will be attracted to the electromagnetic plate 34 and move towards the electromagnetic plate 34 via the slide rail 321, opening the first air vent 311. When the power box is de-energized, the electromagnetic plate 34 is not magnetic, the shielding plate 33 will be attracted to the magnetic plate 341 and move towards the magnetic plate 341, sealing the first air vent 311, thus achieving the magnetic closure of the power box and facilitating the power box to be energized and used in different states.

[0031] It is worth noting that the shield 33 will have a second air vent 331 that cooperates with the first air vent 311. Furthermore, a roller 323 is slidably mounted in the slide rail 321, and the roller 323 can be fixedly connected to the shield 33. The roller 323 is then connected to the upper and lower ends of the slide rail 321 by folding springs 322. Both ends of the folding springs 322 can be equipped with damping pads that are in close contact with the slide rail 321. The shield 33 is elastically slidably mounted on the slide rail 321. Utilizing the elastic return of the folding springs 322 and the friction between the damping pads and the slide rail 321, the electromagnetic plate 34 and the magnetic plate 341 are elastically connected to the shield 33, facilitating the opening or closing of the shield 33 using the second air vent 331 to the first air vent 311, thus increasing the opening and closing sensitivity of the shield 33. To continuously dehumidify the existing ventilation openings 12, such as... Figure 2 and 5 As shown, a one-way ventilation component can be used to set the ventilation opening 12 as an outlet-only structure, thus achieving moisture-proof treatment at the electromagnetic box ventilation opening 12. Figure 5 As shown, the ventilation assembly 4 includes a connecting seat 41 fixed to the housing 11. Multiple right-angle bearings are provided on the inner side of the connecting seat 41. A sealing plate 42 is rotatably mounted on one side of each right-angle bearing. Furthermore, an elastic strip 43 is provided on the side of the sealing plate 42 near the ventilation opening 12. The simultaneous use of the right-angle bearings and the elastic strip 43 facilitates the restriction of the rotation angle and direction of the sealing plate 42, providing favorable conditions for the ventilation opening 12 to only allow airflow without inflow. The edges of the multiple sealing plates 42 overlap, sealing the connecting seat 41. The elastic strip elastically connects the multiple sealing plates 42, facilitating the sealing of the sealing plate 42. 2. Closure: When the power supply box is in use, the internal heat dissipation device uses a fan to circulate internal air with external gas. When the fan is working, the gas generated first enters the connector 41, and pushes the sealing plate 42 through the right-angle shaft seat to open the vent 12 and blow it to the outside, realizing air circulation and dehumidification of the power supply box. When the power supply box is powered off, the fan stops blowing air, the sealing plate 42 is reset by the elastic strip, and then the connector 41 can be closed to achieve the sealing of the vent 12, forming a modular moisture-proof at the vent 12, which can then seal the internal components of the power supply box and increase the moisture-proof effect of the power supply box.

[0032] To further ensure the dryness and moisture-proofness of the power supply box, a perforated box 5 can be fitted inside the box body 11, creating a gap between the perforated box 5 and the box body 11. Then, drying particles are filled between the perforated box 5 and the box body 11 to dehumidify the inside of the power supply box, facilitating long-term use of the power supply box.

[0033] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
