[0014] The utility model is described in detail below with reference to the accompanying drawings:

[0015] As shown in Figure 1, Figure 2 and Figure Figure 3As shown, a dustproof vector inverter described in the utility model includes a protective box 1, and the front and rear sides of the left sides of the upper and lower parts of the protective box 1 are respectively fixedly connected with fixed plates 2, and the inner middle and outer sides of the fixed plates 2 are respectively provided with through holes; the openings in the middle parts of the front and rear parts of the protective box 1 are respectively fixedly connected with filter screens 3; a box door 4 is installed on the right part of the protective box 1, and the upper and lower sides of the right rear side of the box door 4 are respectively fixedly connected with handles 5; the inner middle part opening of the box door 4 is inlaid with an observation glass plate 6; the inner left middle part of the protective box 1 is fixedly connected with a vector inverter body 7.

[0016] One of the dustproof vector inverters also includes a dustproof cleaning component 8, and the dustproof cleaning component 8 is fixedly connected to the middle right part of the box door 4; the dustproof cleaning component 8 is buckled on the outer side of the observation glass plate 6, which is conducive to achieving the effect of facilitating the protection of the cleaning component and can effectively avoid the problem of large amounts of dust adhering to the observation glass plate and the cleaning component.

[0017] In this embodiment, combined with the Figure 4 As shown, the dust-proof cleaning assembly 8 comprises an annular dust-proof frame 81, an insert block 82 is inserted into the right side of the inside of the annular dust-proof frame 81, and an annular groove is provided in the middle part of the outer wall of the insert block 82, wherein a sealing ring 83 is sleeved on the inner side of the annular groove; the outer wall of the sealing ring 83 is arranged in sliding contact with the inner wall of the annular dust-proof frame 81; a baffle plate 84 is fixedly connected to the right part of the insert block 82, and the baffle plate 84 is located on the right side of the annular dust-proof frame 81, wherein an operating handle 85 is fixedly connected to the middle part of the right part of the baffle plate 84; a fleece-surface Velcro 86 is glued to the left part of the insert block 82, and a hook-surface Velcro 87 is glued to the left part of the fleece-surface Velcro 86, wherein a cleaning sponge sheet 88 is fixedly connected to the left part of the hook-surface Velcro 87, and when the cleaning sponge sheet 88 needs to be cleaned, the operator can directly tear off the hook-surface Velcro 87 from the fleece-surface Velcro 86, and then the operator can clean the cleaning sponge sheet 88, thereby achieving the effect of facilitating the cleaning of the cleaning sponge sheet 88.

[0018] In this embodiment, specifically, the left portion of the annular dustproof frame 81 is fixedly connected to the middle portion of the right portion of the door 4 , and the annular dustproof frame 81 is buckled onto the outer side of the observation glass plate 6 .

[0019] In this embodiment, specifically, the left portion of the cleaning sponge sheet 88 is pressed against the right portion of the observation glass plate 6 .

[0020] In this embodiment, specifically, the outer diameter of the sealing ring 83 is larger than the inner diameter of the annular dustproof frame 81, so that when the plug block 82 is inserted into the interior of the annular dustproof frame 81, the sealing ring 83 will be squeezed by the annular dustproof frame 81 and the plug block 82, thereby effectively increasing the friction between the plug block 82 and the annular dustproof frame 81, thereby avoiding the problem of the plug block 82 falling off from the interior of the annular dustproof frame 81 by itself.

[0021] In this embodiment, specifically, the sealing ring 83 is a rubber ring.

[0022] In this embodiment, specifically, the cleaning sponge sheet 88 is a polyvinyl alcohol sponge sheet.

[0023] In this embodiment, specifically, the annular dustproof frame 81 is an annular stainless steel frame.

[0024] In this embodiment, specifically, the protection box 1 is a stainless steel box with an opening on the right.

[0025] In this embodiment, specifically, the filter screen 3 is a primary plate type air filter screen.

[0026] In this embodiment, specifically, the observation glass plate 6 is a transparent tempered glass plate.

[0027] In this embodiment, when protecting the cleaning component and the observation glass plate 6, the operator can directly pick up the baffle 84 through the operating handle 85 and insert the plug block 82 into the annular dustproof frame 81. Since a sealing ring 83 is provided on the outer wall of the plug block 82, the gap between the annular dustproof frame 81 and the plug block 82 can be sealed by the sealing ring 83. Since the annular dustproof frame 81 is buckled on the outer side of the observation glass plate 6, and the cleaning sponge sheet 88 is located in the annular dustproof frame 81, the cleaning component and the observation glass plate 6 will not be contaminated by a large amount of dust, thereby achieving the effect of facilitating the protection of the cleaning component and effectively avoiding the problem of a large amount of dust adhering to the observation glass plate 6 and the cleaning component. When observing the working condition of the vector inverter body 7 through the glass plate 6, the operator can first rotate the baffle 84 through the operating handle 85, so that the baffle 84 drives the cleaning sponge 88 to rotate through the plug 82, the fur-side Velcro 86 and the hook-side Velcro 87, and the cleaning sponge 88 will wipe the observation glass plate 6. Because the observation glass plate 6 and the cleaning component are not contaminated by a large amount of dust, no dust marks will be generated on the observation glass plate 6 after wiping. Finally, the operator can pull the baffle 84 to the right through the operating handle 85 until the cleaning component is moved out of the inside of the annular dustproof frame 81, and then the operator can observe the working condition of the vector inverter body 7 through the observation glass plate 6.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
