Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] like Figure 1-4 As shown, the present application provides a centrifugal fan with a detachable supporting device, including a base 1, on which a centrifugal fan body 2 is mounted, an air inlet pipe 3 is fixedly connected to one side of the centrifugal fan body 2, and a power source is connected so that the centrifugal fan body 2 works, air is sucked in through the air inlet pipe 3, and finally sent out from the air outlet pipe at the other end of the centrifugal fan body 2, thereby blowing out a strong air flow.

[0031] like Figure 2 and Figure 3 As shown, a replacement mechanism 4 is provided on the air inlet pipe 3, and the replacement mechanism 4 includes a rectangular groove 43 opened on the air inlet pipe 3, and a filter screen 41 is slidably connected inside the rectangular groove 43, and a handle 49 is fixedly connected to the filter screen 41, and a plurality of rubber sleeves are fixedly connected to the handle 49. When a person needs to replace the filter screen 41, the person can hold the handle 49, so as to facilitate the person's hand to exert force on the filter screen 41, and then the filter screen 41 can be inserted into the air inlet pipe 3 through the rectangular groove 43, thereby realizing the preliminary installation between the filter screen 41 and the air supply pipe.

[0032] The opposite sides of the air inlet pipe 3 are fixedly connected with a fixing frame 44, and the inner wall of the fixing frame 44 is slidably connected with a square plate 45. Two plug posts 48 are symmetrically fixedly connected to the square plate 45. A circular column 46 is fixedly connected to the side of the square plate 45 away from the plug posts 48, and the circular column 46 is slidably connected to the fixing frame 44. The air inlet pipe 3 is provided with a plug hole 42 at a position relative to the plug post 48, and the plug hole 42 penetrates the air inlet pipe 3 and extends to one side of the filter screen 41. A spring 47 is sleeved on the circular column 46, and the two ends of the spring 47 are respectively connected to the fixing frame 4 4 is fixedly connected to the square plate 45, and the end of the circular column 46 away from the square plate 45 is fixedly connected to the ball. Before installing the filter screen 41, the personnel can pull the two balls away from each other. At this time, the ball will drive the plug post 48 on the square plate 45 to move out of the socket 42 on the filter screen 41. At this time, the personnel can replace the filter screen 41 and release the ball. The plug post 48 will be indirectly affected by the elastic force of the spring 47 and automatically inserted into the socket 42, thereby realizing the complete installation between the filter plate and the air inlet pipe 3.

[0033] like Figure 4As shown, a support mechanism 5 is provided between the base 1 and the centrifugal fan body 2, and the support mechanism 5 includes three telescopic frames 501 fixedly connected to the base 1, one end of the telescopic frame 501 is fixedly connected to a rectangular plate 502, the rectangular plate 502 is fixedly connected to the centrifugal fan body 2, two positioning blocks 504 are symmetrically fixedly connected to the rectangular plate 502, a mounting plate 503 is placed on the rectangular plate 502, and two positioning holes 505 are symmetrically provided on the mounting plate 503.

Square holes 506 are provided on the opposite sides of the mounting plate 503. The setting of the circular column 46 can prevent the plug-in frame 507 from rotating at an angle during the moving rod process. The inner wall of the fixed folding block 508 is threadedly connected with a bolt rod 511, and one end of the bolt rod 511 is rotatably connected to the plug-in frame 507.

When the bracket 507 is inserted into the positioning block 504, the centrifugal fan body 2 and the support mechanism 5 are completely installed.

[0037] Working principle: When personnel need to replace the filter 41, they can vertically insert the filter 41 into the air inlet duct 3 along the direction of the rectangular groove 43, and at the same time insert the column 48 into the socket 42 on the filter 41 to fix the position of the filter 41 on the air inlet duct 3.

[0038] At the same time, in order to facilitate the carrying of the entire centrifugal fan body 2, the centrifugal fan body 2 and the supporting mechanism 5 can be disassembled and assembled, and the positioning block 504 is inserted into the positioning hole 505, thereby realizing the overall positioning and preliminary installation of the centrifugal fan body 2 and the supporting mechanism 5. At the same time, by rotating the bolt rod 511, the bracket 507 is driven to be inserted into the square hole 506 on the positioning block 504, thereby realizing the complete installation between the centrifugal fan body 2 and the supporting mechanism 5. At this time, the personnel can use the electric telescopic rod 512 to realize the height adjustment between the centrifugal fan body 2 and the base 1, thereby meeting the needs of various scenarios.
