[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0028] like Figure 1-Figure 5 As shown, the present application provides a portable exhaust fan for decoration, including a support assembly 20, and an exhaust assembly 10 movably mounted on the support assembly 20, wherein the exhaust assembly 10 is used to improve the air in the decoration room, and the support assembly 20 is used to support the exhaust assembly 10 as a whole, and can also move the exhaust assembly 10 as a whole.

[0029] The exhaust assembly 10 includes a casing 11, on which a motor (not shown) is installed. A wind wheel 15 is installed on the internal bearing of the casing 11, and the output shaft of the motor is fixedly connected to the wind wheel 15. An air outlet pipe 13 is fixedly installed on the casing 11, and the air outlet pipe 13 is an air outlet. At the same time, the casing 11 is an air inlet. When the motor rotates the wind wheel 15, the wind will enter the interior through the air inlet and then be discharged through the air outlet of the air outlet pipe 13, thereby achieving a blowing effect.

[0030] At the same time, a handle 12 is fixedly mounted on the housing 11, and the handle 12 can be picked up by a worker, so that the device can be picked up through the handle 12, and the device can also be transported as a whole, thereby making the device portable to a certain extent.

[0031] A screen 16 is fixedly installed on the air inlet of the casing 11, so that when the wind enters the interior of the casing 11, the wind will come into contact with the screen 16, so that the screen 16 can prevent foreign matter such as dust, hair, and debris from entering the interior of the blower, reducing the risk of damage and improving the efficiency of the equipment.

[0032] At the same time, several groups of card strips 17 are fixedly installed on the screen 16. The ends of the card strips 17 are convex, and several groups of card slots 18 are opened on the casing 11. The card slots 18 can be adapted to the card strips 17. When the screen 16 is installed on the casing 11, the card strips 17 can be clamped in the card slots 18. The raised parts of the card strips 17 will be on the card slots 18, so that the screen 16 can be smoothly installed on the casing 11. At the same time, the raised parts of the card strips 17 can be pressed so that the card strips 17 will be detached at the card slots 18, so that the screen 16 can be quickly removed from the casing 11.

[0033] A power cord port 14 is fixedly mounted on the housing 11 , and a power cord can be mounted on the power cord port 14 , so that the exhaust assembly 10 can be connected to a power source via the power cord to be driven.

[0034] The support assembly 20 includes a base 21, and the bottom of the base 21 is provided with several groups of moving wheels 22, which can contact the ground. At the same time, a bearing block a23 is fixedly installed on the base 21, and a bearing block b24 is rotatably installed on the bearing block a23, and a placement frame 25 is fixedly installed on the bearing block b24. Both ends of the placement frame 25 are fixedly installed with bearing rings 27. The interiors of the two groups of bearing rings 27 are in contact with the outer sides of the casing 11, so that the casing 11 can rotate on the bearing rings 27, and the bearing block b24 can also rotate on the bearing block a23, so that the exhaust assembly 10 can achieve multi-directional angle adjustment when on the support assembly 20, so that the exhaust assembly 10 can be moved while also meeting different angle requirements, and the placement frame 25 is supported by the base 21, so that the exhaust assembly 10 can be supported and placed on the support assembly 20, so that the exhaust assembly 10 can avoid being picked up by the staff for a long time, and can also be moved by the moving wheels 22.

[0035] The placement rack 25 is provided with a wire groove 26 near the power cord port 14, so that when the housing 11 is rotated by the bearing ring 27, a portion of the power cord will be on the wire groove 26. The wire groove 26 allows the housing 11 and the power cord to be adjusted normally, preventing the placement rack 25 from blocking the power cord.

[0036] At the same time, a collecting tray 28 is fixedly mounted on the placement rack 25 so that the power cord of the exhaust assembly 10 can be wound and collected on the collecting tray 28 after use, thereby preventing the power cord from being easily lost.

[0037] In addition, a fixing bar 29 is fixedly installed on the placement rack 25 near the collection tray 28, and a spring 210 is fixedly installed inside the fixing bar 29. At the same time, a pressure rod 211 is fixedly installed on the spring 210. The pressure rod 211 is close to the collection tray 28, and the pressure rod 211 can be continuously pressed downward by the spring 210. After the power cord is wound and collected on the collection tray 28, the pressure rod 211 is pressed downward by the spring 210, so that the pressure rod 211 can contact the wound power cord, thereby preventing the power cord from falling off after being collected on the collection tray 28.

[0038] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
