Existing electric control boxes often use internal fans to dissipate heat. However, during the heat dissipation process, dust in the air is often sucked into the electric control box. The floating dust is easy to adhere to the surface of the equipment inside the electric control box, affecting the heat dissipation of the equipment. When the dust floats near the heat dissipation port, it is easy to adhere to the heat dissipation port, blocking the heat dissipation port and reducing the heat dissipation effect.

[0024] Example:
[0025] like Figure 1-Figure 5 As shown, an electric control box for a high-voltage generating device comprises a box body 1 and a box door 2, the box door 2 is hinged to the box body 1, the box body 1 has an air inlet 3 and a heat dissipation port 4, the positions of the air inlet 3 and the heat dissipation port 4 correspond, a mounting shell 5 fixedly connected to the box body 1 is arranged at the air inlet 3, a motor 6 is fixedly installed in the mounting shell 5, a fan 7 is fixedly sleeved on the output end of the motor 6, a ventilation duct 8 is arranged at the air inlet 3, the ventilation duct 8 is located outside the box body 1, and the ventilation duct 8 is fixedly connected to the box body 1, a dust removal part 9 is arranged at one end of the ventilation duct 8 away from the box body 1, and the dust removal part 9 is used for filtering dust in the air to prevent dust from entering the inside of the box body 1 through the air inlet 3.
[0026] In this embodiment, the front of the box body 1 has an opening, and the air inlet 3 and the heat dissipation outlet 4 are respectively located on both sides of the box body 1, and the heat dissipation outlet 4 is in a mesh shape.
[0027] The dust removal unit 9 includes a filter cloth 91 , which is wrapped around the opening of the ventilation pipe 8 . During the heat dissipation process, the fan 7 inhales air, and dust in the air is blocked by the filter cloth 91 and cannot enter the box body 1 .
[0028] The filter cloth 91 is woven from a single synthetic fiber, has a good filtering effect, is not easy to be blocked, and can provide a higher ventilation volume than other filter materials. The filter cloth 91 is easy to clean and regenerate, has low cost, and is a preferred filter material.
[0029] The filter cloth 91 and the ventilation pipe 8 are connected by a fastening clamp 92 to prevent the filter cloth 91 from falling off and facilitate the replacement of the filter cloth 91.
[0030] In this embodiment, the fastening clamp 92 is tightened by bolts and nuts to fix the filter cloth 91 on the ventilation pipe 8.
[0031] There are two groups of air inlet 3 and heat dissipation outlet 4, so as to enhance the heat dissipation effect and offset the influence of filter cloth 91 on the ventilation volume.
[0032] A dust cover 41 is provided at the heat dissipation port 4. The dust cover 41 is located outside the box body 1 and is fixedly connected to the box body 1. The bottom of the dust cover 41 has an opening. When the fan 7 is not working, the dust cover 41 can effectively reduce the dust in the air from floating into the box body 1 from the heat dissipation port 4. When the fan 7 is working, the hot air dissipated from the heat dissipation port 4 returns to the atmosphere from the opening at the bottom of the dust cover 41.
[0033] In this embodiment, the height of the dust cover 41 is greater than the diameter of the heat dissipation port 4 , and the dust cover 41 completely covers the heat dissipation port 4 to achieve a better dust-proof effect.
[0034] The dust cover 41 has a guide plate 42 on one side away from the box body 1 . The guide plate 42 is arranged to be inclined downward in a direction away from the box body 1 . The guide plate 42 can guide the hot air emitted from the heat dissipation port 4 to quickly return to the atmosphere from the opening at the bottom of the dust cover 41 .
[0035] The opening of the box body 1 is provided with matching plates 11 on all sides, and the matching plates 11 are located outside the box body 1. The door 2 is provided with snap-fit plates 21 on all sides, and the widths of the matching plates 11 and the snap-fit plates 21 are consistent. When the door 2 of the electric control box is closed, the snap-fit plates 21 are located on the outside of the matching plates 11, thereby increasing the distance that the dust enters the box body 1 from the door 2, thereby reducing the probability of dust entering the box body 1.
[0036] In this embodiment, the matching plate 11 is arranged perpendicularly to the plane where the opening of the box body 1 is located, and the buckling plate 21 is arranged perpendicularly to the box door 2 .
[0037] The end of the door 2 away from its rotation axis is rotatably sleeved with a rotating rod 22, and the outer ring of the rotating rod 22 extending out of the inner side of the door 2 is fixedly sleeved with a lock plate 23, and the outer ring of the rotating rod 22 extending out of the outer side of the door 2 is fixedly sleeved with a knob 24. The inner side wall of the box body 1 close to the matching plate 11 is fixedly connected with an L-shaped baffle 12. When the door 2 needs to be closed, the door 2 is buckled with the box body 1, and the knob 24 is turned clockwise to drive the rotating rod 22 and the lock plate 23 to rotate until the lock plate 23 is rotated. The lock plate 23 is in a horizontal state and the box door 2 is locked. When the box door 2 needs to be opened, the knob 24 is turned counterclockwise to drive the rotating rod 22 and the lock plate 23 to rotate until the lock plate 23 rotates out of the baffle 12 and is in a vertical state. The box door 2 can be opened by pulling the knob 24, thereby realizing the rapid opening and closing of the box door 2 and facilitating the maintenance of the electric control box.
[0038] The knob 24 has a pointing slot 241 , and the position of the pointing slot 241 corresponds to the position of the lock plate 23 . The state of the lock plate 23 can be determined by observing the pointing slot 241 , so as to control the opening and closing of the electric control box door 2 .
[0039] In this embodiment, the pointing slot 241 is located at a side of the knob 24 away from the door 2 , so that the pointing slot 241 is easy to observe.
[0040] The present embodiment proposes an electric control box for a high-voltage generating device which can effectively prevent dust. When the electric control box is not working, the dust cover 41 can effectively reduce the dust in the air from floating into the box body 1 from the heat dissipation port 4. The filter cloth 91 can filter the dust in the air to prevent the dust from entering the box body 1 through the air inlet 3. When the electric control box is working, the fan 7 rotates to suck the air with lower outside temperature into the electric control box through the air inlet 3. During this process, the dust in the air will be blocked by the filter cloth 91 and cannot enter the electric control box. The air with higher temperature in the electric control box will be released from the heat dissipation port 4 and finally return to the atmosphere from the opening at the bottom of the dust cover 41. When the box door 2 is closed, even if the dust in the air enters from the gap between the box door 2 and the box body 1, it will often only fall on the matching plate 11 but will not enter the box body 1, thereby achieving the effect of effective dust prevention. The heat dissipation port 4 will not be blocked and will not affect the heat dissipation effect of the electric control box.
[0041] The embodiment of the present embodiment is described above in conjunction with the accompanying drawings, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present embodiment, ordinary technicians in this field can also make many forms without departing from the purpose of the present embodiment and the scope of protection of the claims, all of which are within the protection of the present embodiment.
