Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] See also Figure 1-5A stably supported silent floor fan comprises a base 1, a non-slip pad 2 is fixedly connected to the bottom of the base 1, a support rod 3 is threadedly connected to the base 1, a moving rod 6 is connected to the support rod 3 through an adjustment component 5, a stabilizing mechanism 4 is arranged on the moving rod 6, a fan body 7 is fixedly connected to the moving rod 6, a protective cover is arranged outside the fan blades of the fan body 7, and a plurality of ventilation holes are opened on the protective cover, and the setting of the protective cover can prevent the user from being injured due to accidentally touching the fan blades during use, and the setting of the ventilation holes, To ensure that the wind generated by the fan blades can be transmitted through the ventilation holes, the stabilizing mechanism 4 includes a fixed block 41, the fixed block 41 is fixedly connected to the moving rod 6, the moving rod 6 is rotatably connected to the rotating rod 42, the rotating rod 42 is slidably connected to the fixed rod 43, a slide plate 44 is slidably connected to the inner wall of the rotating rod 42, a clamping block 45 is fixedly connected to the slide plate 44, a clamping hole of the same size as the clamping block 45 is opened on the inner wall of the fixing rod 43, and the cross-section of the clamping block 45 is trapezoidal. The shape of the clamping block 45 ensures that when the slide plate 44 is not subjected to external force, the fixed The rod 43 can move unidirectionally on the rotating rod 42, the slide plate 44 is elastically connected to the inner wall of the rotating rod 42 through a spring 46, the rotating rod 42 is elastically connected to the fixed rod 43 through a tension spring 47, and a connecting hole 48 is provided at one end of the fixed rod 43 away from the rotating rod 42. A connecting seat 49 is fixedly connected to the base 1, and a screw 410 is threadedly connected to the connecting seat 49. An air pressure chamber 411 is provided inside the fixed block 41, and a push block 412 is slidably connected to the inner wall of the air pressure chamber 411. Trapezoidal block 413, trapezoidal block 413 is elastically connected to the inner wall of air pressure chamber 1 411 through spring 2 414, and fixed block 41 is slidably connected with control ring 415, by changing the position between rotating rod 42 and fixed rod 43, it is ensured that when fan main body 7 is at different heights, the fan main body 7 can be supported. And through the joint action of air pressure chamber 1 411, push block 412, trapezoidal block 413, spring 2 414 and control ring 415, fixed rod 43 can be automatically reset, so that the staff can adjust the spacing conveniently.

[0023] When in use, the staff first adjusts the distance between the support rod 3 and the moving rod 6 by adjusting the assembly 5, and fixes them by adjusting the assembly 5. When the fixation is completed, the staff first moves the control ring 415 upwards to make the control ring 415 leave the area where the trapezoidal block 413 is located, so that the trapezoidal block 413 moves outward under the drive of the spring 414, so that the air pressure inside the air pressure chamber 1 411 is reduced, so that the push block 412 moves towards the direction close to the air pressure chamber 1 411 under the action of the air pressure, so that the slide plate 44 is not squeezed by the push block 412. The sliding plate 44 is pressed by the spring 46 to move to the outside of the rotating rod 42, and the fixing rod 43 and the rotating rod 42 are relatively fixed through the clamping block 45 and the clamping hole on the fixing rod 43. At this time, the staff pulls the fixing rod 43. Since the fixing rod 43 contacts the inclined surface of the clamping block 45 when moving, it can squeeze the clamping block 45. When the staff stops pulling the fixing rod 43, although the fixing rod 43 has the tension of the tension spring 47, the sliding plate 44 is squeezed by the spring 46 so that the clamping block 45 enters the clamping hole on the fixing rod 43. When the rod 43 moves toward the direction close to the tension spring 47, the fixing rod 43 will contact the longer side of the block 45, so the fixing rod 43 cannot move. At this time, the staff puts the end of the fixing rod 43 into the inside of the connecting seat 49, and rotates the screw 410 so that the screw 410 enters the connecting hole 48 opened on the fixing rod 43, so that the fixing rod 43 is fixed. When it is necessary to release the limit, the staff first rotates and removes the screw 410, and then moves the control ring 415 downward, so that the control ring 415 squeezes the trapezoidal block 413, so that the trapezoidal block 413 is 13 moves in the direction approaching the air pressure chamber 411, thereby reducing the volume inside the air pressure chamber 411, thereby increasing the air pressure inside the air pressure chamber 411, thereby causing the push block 412 to move in the direction away from the air pressure chamber 411, thereby causing the push block 412 to push the slide plate 44, causing the slide plate 44 to drive the clamping block 45 to move, causing the clamping block 45 to move away from the clamping hole opened on the fixing rod 43, at which time the fixing rod 43 is reset under the pull of the tension spring 47, thereby resetting the fixing rod 43, making it convenient for the staff to store or readjust the length of the fixing rod 43.

[0024] Embodiment 2

[0025] See also Figure 1-6On the basis of the first embodiment, the adjustment component 5 includes a second air pressure chamber 51, which is opened in the inner wall of the support rod 3, and a moving ring 52 is slidably connected to the inner wall of the second air pressure chamber 51. The shape of the second air pressure chamber 51 is annular, and the moving ring 52 is consistent with the cross-sectional shape of the second air pressure chamber 51. By setting the shape of the second air pressure chamber 51, it is ensured that the moving ring 52 can move inside the second air pressure chamber 51. The second air pressure chamber 51 is connected to an airbag 1 53, and the airbag 1 53 is set in the inner wall of the support rod 3. The second air pressure chamber 51 is connected to an airbag 2 54. The end of the moving ring 52 close to the airbag 1 53 is fixedly connected to a spring 3 55, and the end of the spring 3 55 away from the moving ring 52 is fixedly connected to the second air pressure chamber 51 1, and a fixing ring 56 is slidably connected to the outer wall of the support rod 3. The friction between the fixing ring 56 and the support rod 3 is relatively large, and the inner wall of the fixing ring 56 is consistent in shape with the outer wall of the support rod 3. The setting of the friction force ensures that the fixing ring 56 is not easy to move without external force. The shape consistency of the inner wall of the fixing ring 56 and the outer wall of the support rod 3 ensures that the fixing ring 56 can slide on the outer wall of the support rod 3. The movement of the fixing ring 56 enables the moving ring 52 to move inside the air pressure chamber 2 51, and the expansion of the airbag 1 53 fills the gap between the moving rod 6 and the support rod 3, thereby achieving the effect of facilitating the adjustment of the distance between the support rod 3 and the moving rod 6 and making it relatively fixed.

[0026] During use, on the basis of the first embodiment, when it is necessary to adjust the distance between the support rod 3 and the moving rod 6, the staff first moves the fixing ring 56 so that the fixing ring 56 does not squeeze the airbag 2 54. At this time, since the airbag 2 54 is in an inflatable state, the fixing ring 56 moves toward the direction close to the airbag 2 54 under the action of the rebound force of the spring three 55. Therefore, the pressure on the side of the air pressure chamber 2 51 close to the airbag 1 53 is reduced. Therefore, the gas inside the airbag 1 53 enters the air pressure chamber 2 51. At this time, the airbag 1 53 shrinks. The distance between the moving rods 6 can be adjusted. When the adjustment is completed, the staff moves the fixed ring 56 again, so that the fixed ring 56 squeezes the airbag 2 54, so that the gas inside the airbag 2 54 enters the interior of the air pressure chamber 2 51, so that the moving ring 52 moves under the action of air pressure, and the gas on the side of the moving ring 52 close to the airbag 1 53 enters the airbag 1 53, so that the airbag 1 53 expands, so that the airbag 1 53 fills the gap between the support rod 3 and the moving rod 6, so that the support rod 3 and the moving rod 6 reach a relatively fixed state.
