[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0023] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1, combined with Figures 1-4 This embodiment describes a double-door dustproof electrical box, including an electrical box body 1, a box door 2, and a curtain door 3. The electrical box body 1 is connected to the box door 2. The curtain door 3 is installed on the electrical box body 1 and is located inside the box door 2. An inner sealing strip 8 is provided on the electrical box body 1 and is located outside the curtain door 3. An outer sealing strip 9 is provided on the inner side of the box door 2. The box door 2 is fastened to the electrical box body 1, and the inner sealing strip 8 and the outer sealing strip 9 are connected in cooperation.

[0026] The electrical enclosure 1 has a base plate 5 and a side plate 6 installed inside. The base plate 5 and the side plate 6 are arranged perpendicularly. In this embodiment, the base plate 5 and the side plate 6 are integrally formed, and multiple ventilation holes are machined on the base plate 5 and the side plate 6 respectively. Under the action of the base plate 5 and the side plate 6, the interior of the electrical enclosure 1 is divided into a main cavity 10 and a secondary cavity 11. A fan 7 is installed on the side wall of the electrical enclosure 1, and the fan 7 is connected to the secondary cavity 11. The main cavity 10 and the secondary cavity 11 are connected through the multiple ventilation holes on the base plate 5 and the side plate 6.

[0027] When cleaning the dust inside the electrical enclosure 1, turn on the fan 7 and adjust its speed to maximum to create a rapid airflow inside the electrical enclosure 1. This draws the dust from the main chamber 10 through the vents in the bottom plate 5 and side plate 6 into the secondary chamber 11. Since the main chamber 10 houses the electrical components, most of the dust adheres to the side walls of the bottom plate 5 and side plate 6 and enters the secondary chamber 11 under the action of the fan 7. A simple cleaning of the main chamber 10 is sufficient. The secondary chamber 11 does not house any electrical components. The bottom plate 5 and side plate 6 are disassembled and cleaned, and then the dust in the secondary chamber 11 is cleaned. The area of ​​the secondary chamber 11 is smaller than that of the main chamber 10, improving cleaning efficiency and reducing the risk of damaging electrical components during cleaning.

[0028] After cleaning the dust, reinstall the base plate 5 and side plates 6 inside the electrical enclosure 1. Then, pull down the curtain door 3 installed on the top inner side of the electrical enclosure 1, and then fasten the enclosure door 2 onto the electrical enclosure 1, locking the enclosure door 2 with the door lock 4. Most of the dust that enters daily through the hinges or gaps between the enclosure door 2 and the electrical enclosure 1 is blocked by the curtain door 3, effectively preventing excessive dust inside the electrical enclosure 1 from affecting the electrical components and reducing the frequency of cleaning the electrical enclosure 1. During daily use of the electrical enclosure 1, the fan 7 is turned off or adjusted to its minimum speed, which is beneficial for heat dissipation of the electrical components inside the electrical enclosure 1.

[0029] Example 2, combined with Figures 1-4 This embodiment describes a double-door dustproof electrical box. Multiple fixing holes 12 are machined on the back of the electrical box 1. Expansion bolts are driven into the wall through the fixing holes 12 from inside the electrical box 1, thereby fixing the electrical box 1 to the wall.

[0030] Example 3, combined with Figure 5 This embodiment describes a double-door dustproof electrical box. Unlike embodiment 2, this embodiment has multiple connecting pieces 13 welded to the back of the electrical box 1. Expansion bolts pass through the connecting pieces 13 and are driven into the wall to fix the electrical box 1 to the wall.

[0031] This embodiment is merely an exemplary description of the present utility model and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
