[0020] The utility model will be further explained in detail below in combination with the drawings and through examples, and the following examples are the explanation of the utility model, and the utility model is not limited to the following examples.

[0021] Example

[0022] Reference Figure 1 - Figure 4 In this embodiment, a fan with dust filtering function is provided, which is particularly used in the air circulation system of a railway transport carriage, and is particularly used for pre-treating the air before introducing fresh air into the carriage. Specifically, the fan comprises a housing 11 and a blade group 12 rotatably arranged in the housing 11. The front side of the housing 11 is connected and fixed with a front panel 13, and the rear side is connected and fixed with a dust filtering assembly 14. Specifically, the fan is installed in the fresh air introducing device in the carriage, and the rotating blade group 12 arranged in the housing 11 drives the air flow, and the dust filtering assembly 14 connected to the rear side of the housing 11 is used for preliminarily filtering the dust of the incoming fresh air. Therefore, the air is preliminarily filtered before entering the carriage, which not only ensures the input of fresh air, but also reduces the dust and pollutants entering the carriage, so as to purify and introduce fresh air, and help to improve the air quality in the carriage.

[0023] Specifically, in this embodiment, the dust filtering assembly 14 comprises a storage compartment 15 for placing a filter element and a compartment cover 16. A plurality of strip-shaped ventilation holes 17 are formed around the storage compartment 15, and the bottom end of the compartment cover 16 is hingedly connected to the storage compartment 15, and the top end is fixed to the storage compartment 15 by two locking components 18. The storage compartment 15 is used for placing the filter element, and the rear side of the housing 11 is further connected and fixed with a baffle 19, which is used for isolating the filter element to avoid the filter element invading the housing 11 and scratching the internal blade group 12. The filter element adopts a cylindrical structure and is matched with the square profile of the storage compartment 15, and the filter element is replaceable. First, the locking state of the compartment cover 16 is released by operating the locking component 18, then the old filter element is taken out by turning down the compartment cover 16 along the hinge part, and the dust and impurities remaining in the compartment are cleaned (which can be blown out by reversing the rotation of the blade group 12), the compartment cover 16 is closed again after the filter element is in place, and finally the two locking components 18 at the top end of the compartment cover 16 are reset and locked by operating the locking component 18 again.

[0024] Referring to Figure 4 The locking component 18 in the embodiment includes a locking block 21 and a locking hook 22. The locking block 21 is fixedly arranged on the cover 16. The locking hook 22 includes a rotating end 23 and a movable end 24. The rotating end 23 is rotatably arranged on the placing bin 15. The movable end 24 is rotatable about the rotating end 23 and is provided with a protruding structure 25. An arc-shaped locking slot 26 that is matched with the protruding structure 25 is arranged on the locking block 21. The locking or unlocking of the locking component 18 can be realized by manually rotating the locking hook 22 to make the protruding structure 25 of the rotating end 23 slide into or out of the arc-shaped locking slot 26.

[0025] In the embodiment, the dust filtering assembly 14 and the shell 11 are first assembled. The two are fixedly connected through bolts and nuts. Specifically, the dust filtering assembly 14 further includes a fixed frame 27. The placing bin 15 is detachably fixedly connected with the fixed frame 27. Frame holes 28 are arranged at the four corners of the fixed frame 27. A first hole group 29 that is matched with the frame holes 28 is arranged at the four corners of the rear side of the shell 11. During assembly, the fixed frame 27 is first connected with the shell 11. Specifically, the frame holes 28 on the fixed frame 27 are aligned with the first hole group 29. The bolts are sequentially inserted through the two holes (the frame holes 28 and the first hole group 29) and then are fixedly connected through the nuts.

[0026] After the dust filtering assembly 14 and the shell 11 are assembled, the front panel 13 is then assembled. In the embodiment, the front panel 13 and the shell 11 are also detachably fixedly connected through bolts and nuts. Specifically, the front panel 13 includes a fixed frame 34 and a cover plate 35. A plurality of frame holes 36 are arranged on the fixed frame 34. A second hole group 37 that is matched with the mounting hole positions is arranged at the four corners of the front side of the shell 11. During installation, the bolts are first inserted through the second hole group 37 from back to front. Then, the frame holes 36 on the fixed frame 34 are aligned with the second hole group 37. The bolts are simultaneously inserted through the frame holes 36 and then are fixedly connected through the nuts. After the fixed frame 34 is fixedly connected, the cover plate 35 is closed. The cover plate 35 plays a decorative role and can shield the connecting members such as the bolts and nuts. In the embodiment, the fixed frame 34 and the cover plate 35 are both provided with ventilation holes. The bottom end of the cover plate 35 is hingedly connected with the fixed frame 34. The top end is fixedly connected through a spring buckle 41. The spring buckle 41 can be unlocked by being pressed during use. This facilitates the downward flipping and dismounting of the cover plate 35 and the maintenance and repair of the internal structure. Meanwhile, the cover plate 35 also plays a decorative role and shields the connecting members such as the bolts and nuts, thereby ensuring the neatness and beauty of the appearance.

[0027] In this embodiment, the fan is particularly suitable for installation in a railway carriage. The inside of the carriage is provided with a dedicated mounting opening, and the fan is mounted through the mounting structure on the fixing frame 34. Specifically, the fixing frame 34 is symmetrically provided with outwardly protruding mounting buckles 42 on the left and right sides, and the front side of the fixing frame 34 is designed with an extension part 43 extending to the periphery. When installing, the fan is installed from the inside of the carriage, so that the mounting buckles 42 are clamped into the mounting opening reserved in the carriage, and the extension part 43 is tightly fixed with the inner wall of the carriage. Since the design size of the extension part 43 is slightly larger than the mounting opening, the mounting buckles 42 can effectively realize the stable fixation of the fan after being clamped.
