Implementation

[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0024] A fan lifting control knob device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings. Example

[0025] For easier understanding, see Figures 1 to 8 An embodiment of a fan lifting control knob device provided by the utility model includes a light shield 1 installed between a surface shell 11 and a base 12, a knob assembly 2 is arranged on the inner side of the light shield 1, a movable bracket 3 that slides up and down is arranged on the inner side of the light shield 1, and the movable bracket 3 is located below the knob assembly 2, columns 4 are fixedly connected to both sides of the bottom of the inner side of the light shield 1, circular grooves matching the columns 4 are opened on both sides of the movable bracket 3, and the columns 4 are slidably connected to the circular grooves on the movable bracket 3, a sliding groove 10 is opened on the inner wall of the light shield 1, a slider 14 is fixedly connected to the side wall of the movable bracket 3, and the slider 14 slides in the sliding groove 10 in a matching manner.

[0026] It should be noted that the movable bracket 3 can be used to drive the knob assembly 2 to move up and down, and in the process of the movable bracket 3 moving up and down, the slider 4 on the movable bracket 3 is slidably connected to the slide groove 10 on the light shield 1, and the movable bracket 3 slides on the column 4, thereby ensuring that the movable bracket 3 has a relatively stable up and down sliding during the lifting process, avoiding unstable situations such as swinging.

[0027] In an optional embodiment: the knob assembly 2 includes a knob potentiometer installed on the inner side of the movable bracket 3, and a knob shell 13 is fixedly installed on the top of the knob potentiometer.

[0028] It should be noted that the installed knob potentiometer is used to electrically control the fan, and the installed knob housing 13 is used to drive the knob potentiometer.

[0029] In an optional embodiment: a spring 5 is slidably mounted on the side wall of the column 4 , and one end of the spring 5 is supported on one end of the light shield 1 , and the other end of the spring 5 is supported on one end of the movable bracket 3 .

[0030] It should be noted that after the knob assembly 2 reaches the highest point, the machine is turned off and the movable bracket 3 relies on the elastic force of the spring 5 to drive the knob assembly 2 back to the level of the knob shell 13 and the face shell 11.

[0031] In an optional embodiment: a question mark-shaped stopper 9 is fixedly connected to the inner wall of the light shield 1. A drive motor 6 is fixedly installed on one side of the light shield 1, and a transmission shaft 7 is fixedly connected to the output end of the drive motor 6, and a drive member 8 is fixedly connected to the other end of the transmission shaft 7, and the drive member 8 cooperates with the stopper 9.

[0032] It should be noted that the installed driving motor 6 drives the transmission shaft 7 to rotate, and during the rotation of the transmission shaft 7, the driving member 8 can be driven to rotate, and the structure of the driving member 8 cooperates with the question mark-shaped limit block 9;

[0033] When shutting down, see attached Figure 7 The driving member 8 rotates until the rectangular block contacts the arc-shaped portion of the limit block 9 to prevent the driving member 8 from further rotating. At this time, the movable bracket 3 drives the knob assembly to be flush with the surface shell 11.

[0034] When booting, see attached Figure 8 The driving member 8 rotates until the rectangular block contacts the rectangular portion of the limiting block 9, and the driving member 8 stops rotating. At this time, the movable bracket 3 drives the knob assembly to rise to the highest point.

[0035] The knob potentiometer in the present invention is a well-known component and will not be described in detail here.

[0036] Working principle: When in use, the installed drive motor 6 drives the transmission shaft 7 to rotate, and during the rotation of the transmission shaft 7, the drive member 8 can be driven to rotate. The structure of the drive member 8 cooperates with the question mark-shaped limit block 9. When shutting down, see the attached Figure 7 , the driving member 8 rotates until the rectangular block contacts the arc portion of the limit block 9 to prevent the driving member 8 from further rotating. At this time, the movable bracket 3 drives the knob assembly to be flush with the face shell 11. When turning on the machine, see the attached Figure 8 The driving member 8 rotates until the rectangular block contacts the rectangular portion of the limit block 9, and the driving member 8 stops rotating. At this time, the movable bracket 3 drives the knob assembly to rise to the highest point. When shutting down, the movable bracket 3 relies on the elastic force of the spring 5 to drive the knob assembly 2 back to the level of the knob shell 13 and the face shell 11.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
