[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] See also Figure 1-6, a structure 100 for manually controlling the air outlet direction of a tower fan provided by the present invention, the structure 100 for manually controlling the air outlet direction of a tower fan, includes a shell 50, a mounting frame 10 arranged on the shell 50, a plurality of air guide vanes 20 arranged in sequence from top to bottom in the mounting frame 10, and an adjustment assembly 30 for adjusting the angle of the air guide vanes 20 in the mounting frame 10; the adjustment assembly 30 includes a dial 31, a plurality of connecting rods 32 rotatably connected to the air guide vanes 20, and a connecting structure arranged on both sides of the dial 31 and used for transmission connection between the dial 31 and the connecting rod 32. When the dial 31 is rotated, the connecting structure drives the connecting rod 32 to drive the air guide vanes 20 to swing in the mounting frame 10, so as to adjust the angle of the air guide vanes 20 in the mounting frame 10. When using the manual tower fan airflow direction control structure 100 to adjust the tower fan's airflow direction, the user only needs to rotate the dial wheel 31, causing the connecting structure to drive the connecting rod 32 to cause the air guide 20 to swing within the mounting frame 10, thereby adjusting the angle of the air guide 20 within the mounting frame 10, thereby meeting the user's needs for blowing air at different angles and improving the user's experience during use. In addition, by using the connecting rod 32 to rotate with the air guide 20 and using the connecting structure to drive the dial wheel 31 and the connecting rod 32, the structure of the adjustment assembly 30 can be effectively simplified, reducing the number of installation steps and improving installation efficiency.

[0031] like Figure 3 and Figure 4 As shown, in the embodiment provided by the present invention, the connection structure is a crank 33 provided on both sides of the dial wheel 31, and the crank 33 cooperates with the connecting rod 32 to form a crank 33-connecting rod 32 structure. By the crank 33 on both sides of the dial wheel 31 cooperating with the connecting rod 32 to form a crank 33-connecting rod 32 structure, the transmission connection structure between the dial wheel 31 and the connecting rod 32 can be effectively simplified. At the user operation level, the wind direction control of the air guide 20 driven by the connecting rod 32 in the vertical direction can be achieved by rotating the dial wheel 31, thereby effectively simplifying the user's operation of adjusting the angle of the air guide 20 in the mounting frame 10, meeting the user's needs for blowing air at different angles, and thus improving the user's experience during use.

[0032] like Figure 2 、 Figure 3 and Figure 4As shown, in the embodiment provided by the present invention, the crank 33 includes a first driving section 331 connected to both sides of the thumbwheel 31 and a first mating section 332 for transmission connection with the connecting rod 32. A connecting section 333 is perpendicularly disposed between the first mating section 332 and the first driving section 331. The connecting rod 32 includes a second mating section 321 and a second driving section 322 that is rotationally connected to the plurality of air guide vanes 20. The second mating section 321 extends obliquely from the second driving section 322 to the first mating section 332 and is transmission-connected to the first mating section 332. The second mating section 321 is provided with a first rotation groove 3211 into which the first mating section 332 is inserted and rotationally connected. The first driving section 331 of the crank 33 effectively ensures the mating accuracy between the first mating section 332 and the second mating section 321 of the connecting rod 32, thereby effectively ensuring that the end of the first mating section 332 is inserted into the first rotation groove 3211 of the second mating section 321, thereby achieving transmission connection between the first mating section 332 of the crank 33 and the second mating section 321 of the connecting rod 32. In addition, by utilizing the second driving section 322 of the connecting rod 32 to rotate in connection with the multiple air guide blades 20, the positioning accuracy of the multiple air guide blades 20 arranged in sequence from top to bottom between the mounting frame 10 and the connecting rod 32 can be effectively guaranteed, and the operation of driving the multiple air guide blades 20 to swing in the mounting frame 10 can be achieved, thereby meeting the user's needs for blowing air at different angles, thereby improving the user's experience during use.

[0033] like Figure 1 、 Figure 5 and Figure 6 As shown, the mounting frame 10 is a hollow structure and forms an installation space for the air guide 20 and an air outlet; the air guide 20 is rotatably connected to the second driving section 322 of the connecting rod 32 and the mounting frame 10 through the first rotating shaft 21 and the second rotating shaft 22; the second driving section 322 is provided with a plurality of second rotating grooves 3221 for the first rotating shaft 21 to be embedded in, and the mounting frame 10 is provided with a plurality of third rotating grooves 11 for the second rotating shaft 22 to be embedded in.

In addition, the two-point support of the first rotating shaft 21 and the second rotating shaft 22 of the air guide blade 20 by the second rotating groove 3221 and the third rotating groove 11 can further improve the stability of the rotational connection of the air guide blade 20 between the mounting frame 10 and the connecting rod 32.

The mounting frame 10 is provided with a plurality of mounting posts 14. Locking members pass through the mounting holes 41 of the air outlet grille 40 and are locked into the mounting posts 14 of the mounting frame 10, thereby securely connecting the air outlet grille 40 to the mounting frame 10. By using locking members such as bolts, studs, and pins to pass through the mounting holes 41 of the air outlet grille 40 and to be locked into the mounting posts 14 of the mounting frame 10, the stability of the fixed connection between the air outlet grille 40 and the mounting frame 10 can be effectively ensured.
