DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a silent floor fan as Figures 1-4 shown, which includes a control panel 1. A telescopic component 2 for adjusting the height of the control panel 1 is provided at the bottom of the control panel 1. An air outlet component 4 for discharging air is provided at the top of the control panel 1. A limiting component 3 for limiting the moving distance of the control panel 1 is provided at the bottom of the control panel 1. The limiting component 3 includes a positioning cylinder 302 provided at the bottom of the control panel 1. A positioning member for fixing the position of the positioning cylinder 302 is provided at the connection between the control panel 1 and the positioning cylinder 302. A limiting hole 303 is formed on one side of the positioning cylinder 302. The telescopic component 2 includes a threaded rod 204, and the threaded rod 204 is inserted and connected inside the limiting hole 303.

[0022] It should be noted that the provided control panel 1 and the air outlet component 4 are a silent floor fan of model SAF35MA; when the control panel 1 is moved upward and the threaded rod 204 is brought into contact with the inner wall of the bottom end of the limiting hole 303, due to the pulling of the threaded rod 204, the positioning cylinder 302 cannot move further, thereby restricting the moving distance of the control panel 1 through this design.

[0023] Specifically, the telescopic component 2 further includes an extension rod 201 fixedly connected to the bottom end of the control panel 1. A fixed sleeve 203 is sleeved at the bottom of the extension rod 201. The threaded rod 204 is threadedly inserted and connected to one side of the fixed sleeve 203. Both the extension rod 201 and the fixed sleeve 203 are inserted and connected inside the positioning cylinder 302. One end of the threaded rod 204 is fixedly connected with a torsion cap 202 for rotating the threaded rod 204.

[0024] It should be noted that the hole opened in the middle of the fixed sleeve 203 is adapted to the extension rod 201, enabling the extension rod 201 to move inside the fixed sleeve 203. A threaded hole adapted to the threaded rod 204 is opened on one side of the fixed sleeve 203. One end of the threaded rod 204 is inserted into the fixed sleeve 203 through the threaded hole, and the extension rod 201 is squeezed. Thus, when it is necessary to fix the position of the extension rod 201, by turning the threaded rod 204, it moves towards the side of the extension rod 201, and the extension rod 201 is squeezed and fixed by the threaded rod 204 and the inner wall on one side of the fixed sleeve 203, thereby preventing the extension rod 201 from moving further and completing the fixing of the height of the floor fan. The set twist cap 202 is used to rotate the threaded rod 204.

[0025] Specifically, the positioning member includes a threaded cylinder 301 fixedly connected to the bottom end of the control panel 1, and the positioning cylinder 302 is threadedly inserted and connected to the bottom of the threaded cylinder 301.

[0026] It should be noted that threads are opened at the top end of the positioning cylinder 302 for fixing the positioning cylinder 302 inside the threaded cylinder 301 through the opened threads when it is necessary to fix the position of the positioning cylinder 302.

[0027] Furthermore, when it is necessary to fix the position of the positioning cylinder 302, first, the positioning cylinder 302 is sleeved on the outer wall of the fixed sleeve 203, the limiting hole 303 opened on the positioning cylinder 302 is aligned with the threaded hole opened on the fixed sleeve 203, the threaded rod 204 is passed through the limiting hole 303, and one end of it is inserted into the threaded hole. Then, the extension rod 201 at the bottom end of the control panel 1 is passed through the positioning cylinder 302, and its end is inserted into the fixed sleeve 203. The positioning cylinder 302 is fixed at the bottom of the threaded cylinder 301 through the opened threads. Thus, when the control panel 1 needs to adjust the height, the control panel 1 drives the extension rod 201 and the positioning cylinder 302 to move, and the moving distance of the control panel 1 and the extension rod 201 is limited by the positioning cylinder 302 that limits the moving distance.

[0028] Specifically, a support component 5 for fixing the position of the telescopic component 2 is arranged at the bottom of the telescopic component 2. The support component 5 includes a chassis 501 threadedly sleeved on the bottom end of the fixed sleeve 203, and a plurality of support blocks 502 are symmetrically and fixedly connected to the center of the bottom end of the chassis 501.

[0029] It should be noted that the set chassis 501 is disc-shaped, and support blocks 502 are symmetrically arranged at the center of the bottom end of the chassis 501 to provide support for the fixed sleeve 203. By means of the chassis 501, the weight at the bottom end of the fixed sleeve 203 is increased, which helps to lower the center of gravity, makes the whole device more stable, ensures that the fan will not tilt or shake during operation, thereby reducing the occurrence of accidents and increasing the safety in use. A thread is sleeved at the bottom end of the fixed sleeve 203, and a thread groove is formed at the top end of the chassis 501. When it is necessary to fix the bottom end of the fixed sleeve 203 to the top end of the chassis 501, the thread formed at the bottom end of the fixed sleeve 203 is directly inserted into the thread groove formed at the top end of the chassis 501, so as to fix the two of them.

[0030] Specifically, the air outlet assembly 4 includes a motor 401 arranged at the top end of the control panel 1. The output end of the motor 401 is fixedly connected with a fan blade 402, and a protective cover 403 for protecting the fan blade 402 is fixedly connected to one side of the motor 401.

[0031] It should be noted that the set control panel 1 is used to control the opening and closing of the motor 401. The set fan blade 402 is fixed to the output end of the motor 401. During use, the fan blade 402 is driven to rotate by the motor 401. The set protective cover 403 is used to prevent the user from contacting the high-speed rotating fan blade 402, so as to protect the user.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
