[0024] As a technical optimization solution of the utility model, by setting a positioning mechanism 7, when the user needs to stop cleaning the protective mesh cover 3, the user can rotate the scraper 5, and then the scraper 5 will drive the positioning frame 71 and the telescopic rod 72 and the magnetic block 73 to rotate. When the magnetic block 73 corresponds to the positioning groove 74, the user moves the magnetic block 73 to the rear side, and then the back side of the magnetic block 73 will be magnetically adsorbed to the rear side of the inner wall of the positioning groove 74, and then the scraper 5 can be positioned to prevent the scraper 5 from being blown to rotate during the normal use of the fan body 2.

[0025] refer to Figure 3 The adjustment assembly 10 includes a screw rod 101 , the front side of the screw rod 101 is fixedly connected to the back side of the connecting rod 8 , and the rear side of the surface of the screw rod 101 is threadedly connected with a screw sleeve 102 .

[0026] As a technical optimization scheme of the utility model, by setting an adjustment component 10, if the user needs to adjust the cleaning force when using the force plate 9, the user can synchronously rotate the two screw sleeves 102, and then use the threaded connection between the screw sleeve 102 and the screw rod 101, so that the screw sleeve 102 will drive the screw rod 101 to move when it rotates, and the screw rod 101 will drive the force plate 9 to move during the movement, so that the distance between the force plate 9 and the fan body 2 is adjusted.

The extension plate 16 is then welded to the force-bearing plate 9 to improve the fixing effect of the extension plate 16, thereby preventing the extension plate 16 from falling and breaking during long-term use.

[0035] The working principle and use process of the utility model are as follows: before the user starts the fan body 2, the user can use the movable connection between the fan body 2 and the adjustment frame 1 to adjust the blowing angle of the fan body 2, and then the fan body 2 can be started. When the fan body 2 is used for a long time and there is too much dust attached to the protective mesh cover 3, the force plate 9 can be used to block part of the airflow blown out when the fan body 2 is turned on, and the force plate 9 is set to be inclined so that the blocked airflow will push the force plate 9 to rotate when it hits the force plate 9, and then the force plate 9 will drive the scraper 5 to rotate, and then the scraper 5 will clean the dust attached to the protective mesh cover 3. When the user needs to stop cleaning the protective mesh cover 3, the user can rotate the scraper 5, and then the scraper 5 will drive the positioning frame 71, the telescopic rod 72 and the magnetic block 73 to rotate. When the magnetic block When 73 corresponds to the positioning groove 74, the user moves the magnetic block 73 to the rear side, and then the back side of the magnetic block 73 will be magnetically adsorbed to the rear side of the inner wall of the positioning groove 74, and then the scraper 5 can be positioned to prevent the scraper 5 from being blown to rotate during the normal use of the fan body 2. When the user needs to adjust the cleaning force during the use of the force plate 9, the user can rotate the two screw sleeves 102 synchronously, and then use the threaded connection between the screw sleeve 102 and the screw rod 101 to make the screw sleeve 102 drive the screw rod 101 to move when it rotates, and the screw 101 will drive the force plate 9 to move during the movement, so that the distance between the force plate 9 and the fan body 2 is adjusted, and the greater the distance between the force plate 9 and the fan body 2, the lower the airflow size received by the force plate 9 will be, so that the cleaning force of the scraper 5 can be adjusted, and it has the ability of auxiliary cleaning.

[0036] To sum up: the adjustable fan, by setting a force-bearing plate 9, can use the force-bearing plate 9 to block part of the airflow blown out when the fan body 2 is turned on, so that the blocked airflow will push the force-bearing plate 9 to rotate when it hits the force-bearing plate 9, and then the force-bearing plate 9 will drive the scraper 5 to rotate and clean, which solves the problem that the protective mesh cover used to protect the fan will be contaminated with a large amount of impurities and dust in the air on the surface after long-term use, causing the protective mesh cover to be too dirty. Conventional cleaning methods usually require users to hold a wet rag to clean it, which wastes manpower and time, and also requires the fan to be turned off, thereby reducing the use effect.
