[0035] In order to solve the above problems, please refer to Figures 1 to 3 The dustproof structure assembly provided by the utility model is described. The dustproof structure assembly comprises a panel grille 1, a support framework 3 and a dustproof screen 5. The edge of the rear side of the panel grille 1 is provided with a framework buckle 2. The support framework 3 is of a grid structure, and the edge of the rear side of the support framework 3 is provided with a clamping groove 4. The support framework 3 is arranged at the rear side of the panel grille 1. The framework buckle 2 is clamped with the clamping groove 4 to limit the displacement of the support framework 3 in the front-rear direction. The dustproof screen 5 is integrally connected to the support framework 3 and can cover the grille opening of the panel grille 1.

[0036] In this embodiment, the front side of the device body is provided with an opening, and the panel grille 1 is detachably arranged at the opening of the front side of the device body.

[0037] In this embodiment, in order to achieve lightweight and low-cost setting, the support framework 3 is preferably made of plastic, and the material of the dustproof screen 5 can be metal, nylon fiber, etc. The dustproof screen 5 and the support framework 3 can be integrally connected through a secondary injection molding process. If the secondary injection molding process is used to achieve the integral connection, the dustproof screen 5 and the support framework 3 are integrally connected, the connection strength between the two is high, and the connection of the edge of the dustproof screen 5 and the support framework 3 is more sufficient, and the dustproof screen 5 is more relaxed.

[0038] In this embodiment, the support framework 3 is pushed forward to realize the clamping of the framework buckle 2 and the clamping groove 4, and the support framework 3 is moved backward to realize the separation of the framework buckle 2 and the clamping groove 4.

Meanwhile, since the dustproof net 5 covers the grille opening of the panel grille 1, the reliability of dustproof filtration can be effectively ensured. If the dustproof net 5 needs to be cleaned, the panel grille 1 is detached from the equipment body, and then the support framework 3 together with the dustproof net 5 is detached from the rear side of the panel grille 1, so that the support framework 3 and the dustproof net 5 can be cleaned separately, without affecting the components that need to be waterproofed arranged on the panel grille 1, effectively avoiding the problem of forming a cleaning dead angle between the traditional panel and the filter net, greatly reducing the cleaning difficulty, directly replacing the dustproof layer in the case of serious blockage of the dustproof net 5 and difficult cleaning, and optimizing the cleaning and use cost.

[0040] In some embodiments, referring to Figures 1 to 7 , the support framework 3 has longitudinally arranged support bars 310 and transversely arranged support bars 320, and the panel grille 1 has longitudinally arranged grille bars 120 and transversely arranged grille bars 130. In the front-rear direction, the longitudinally arranged support bars 310 are located directly behind the longitudinally arranged grille bars 120, and the transversely arranged support bars 320 are located directly behind the transversely arranged grille bars 130, so as to avoid the longitudinally arranged support bars 310 and the transversely arranged support bars 320 from hindering the ventilation effect of the grille opening. In specific implementation, in a plane perpendicular to the front-rear direction, the orthographic projection contour line of the transversely arranged support bars 320 does not protrude from the orthographic projection contour line of the transversely arranged grille bars 130, and the orthographic projection contour line of the longitudinally arranged support bars 310 does not protrude from the orthographic projection contour line of the longitudinally arranged grille bars 120, so as to avoid hindering the ventilation to the greatest extent.

[0041] In some embodiments, referring to Figures 1 to 3 , Figure 6 and Figure 7 , the rear side of the panel grille 1 is provided with support ribs 6, which are attached to the outer circumferential surface of the support framework 3, so as to limit the displacement of the support framework 3 in a direction perpendicular to the front-rear direction. By arranging the support ribs 6, the contact area between the support ribs 6 and the support framework 3 is small, and the assembly error between the support ribs 6 and the support framework 3 is small, so that the support framework 3 can be effectively limited. In specific implementation, a plurality of support ribs 6 are distributed along the circumference of the panel grille 1.

[0042] In some specific embodiments, referring to Figure 3The support rib 6 has a guide surface 601 gradually inclined inward from back to front, and a skeleton accommodating space with gradually increasing cross-sectional area from back to front is enclosed between the plurality of support ribs 6. Since the rear side of the skeleton accommodating space is large, the support skeleton 3 is facilitated to enter. With the support skeleton 3 gradually advancing forward, the support skeleton 3 is gradually aligned with the panel grille 1 under the guidance of the guide surface 601, so that the clamping assembly between the support skeleton 3 and the panel grille 1 is more convenient and efficient.

[0043] In some embodiments, referring to Figure 3 , Figure 6 and Figure 7 , the support rib 6 includes a plurality of first support ribs 610 respectively arranged on the upper side and the lower side of the panel grille 1, and a plurality of second support ribs 620 arranged on the left side and the right side of the panel grille 1; the first support rib 610 has a first rib strutting plate 611, a second rib strutting plate 612 and a contact strutting plate 613 connected in sequence from outside to inside, the first rib strutting plate 611 and the contact strutting plate 613 are both perpendicular to the second rib strutting plate 612, the second rib strutting plate 612 is perpendicular to the inside-outside direction, and the inside edge of the contact strutting plate 613 forms the guide surface 601. This embodiment exemplarily shows a rectangular panel grille 1, the long side of which is parallel to the left-right direction, and the short side is parallel to the up-down direction. In this embodiment, the first rib strutting plate 611, the second rib strutting plate 612 and the contact strutting plate 613 cooperatively form a rib structure with a cross-shaped cross section, so that the first support rib 610 has higher bending and torsional strength and can still maintain good structural stability after being in close contact with the support skeleton 3. Therefore, the first support rib 610 is applied to the upper side and the lower side of the panel grille 1 which is more affected by gravity, to ensure the limiting effect of the upper side and the lower side.

[0044] Optionally, the second support rib 620 on the left and right sides has a rib structure with a one-shaped cross section, as shown in 2. Alternatively, the second support rib 620 on the left and right sides can also have a cross-shaped, T-shaped or other cross-sectional structure, which is not limited herein.

[0045] In some embodiments, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the rear side of the panel grille 1 is provided with a main body mounting member 7 capable of being connected with the equipment main body. In order to avoid affecting the installation of the panel grille 1 and the equipment main body, the outer peripheral edge of the support skeleton 3 is provided with an avoidance recess 8 corresponding to the main body mounting member 7.

[0046] Optionally, referring to Figure 2 , Figure 6 and Figure 7The body mounting member 7 includes a body mounting buckle 710 and a body positioning rib 720.

[0047] Alternatively, the body mounting member 7 includes a fastener and a panel mounting hole formed on the panel grid 1. A body mounting hole corresponding to the panel mounting hole is formed on the device body. The fastener (for example, a threaded fastener) penetrates through the panel mounting hole and is connected with the body mounting hole, so as to realize the connection of the panel grid 1 and the device body.

[0048] Optionally, referring to Figure 1 and Figure 4 , the avoidance recess 8 is a trapezoidal groove with a width gradually decreasing from outside to inside. The trapezoidal groove design not only meets the avoidance requirement, but also improves the bearing capacity of the slotted part by virtue of the strong stability of the trapezoidal structure, thereby avoiding affecting the overall structural strength of the support framework 3.

[0049] In some embodiments, referring to Figures 1 to 4 , in order to improve the structural strength of the support framework 3 and facilitate the installation of the dustproof net 5, the support framework 3 further has a support outer frame 330.

[0050] In some embodiments, referring to Figure 4 and Figure 5 , the longitudinal support bars 310 and the transverse support bars 320 divide the inner side of the support outer frame 330 into a plurality of grid spaces 301. The support outer frame 330, the longitudinal support bars 310 and the transverse support bars 320 are provided with a connecting boss 350 on the side facing the grid space 301. The dustproof net 5 is arranged one-to-one corresponding to the grid space 301. The edge of the dustproof net 5 is integrally connected with the rear side of the connecting boss 350, thereby reducing the connection difficulty of the dustproof net 5 and the support framework 3.

[0051] Optionally, the connecting boss 350 is arranged close to the front side of the support outer frame 330, the longitudinal support strip 310 or the transverse support strip 320, and the front side of the connecting boss 350, the front side of the support outer frame 330, the front side of the longitudinal support strip 310 and the front side of the transverse support strip 320 are flush with each other, so that the support framework 3 as a whole has a flat front surface, avoiding forming a dead angle where particles are easy to accumulate, facilitating cleaning, and also facilitating installation with the panel grille 1.
