With continued reference to fig. 1-5, the outer housing 10 includes a base 11, a connecting socket 12, and an outer tube 13. Wherein, the connecting base 12 is rotatably connected to the base 11 (see the following description), the outer tube 13 is correspondingly fixed on the connecting base 12, the outer tube 13 is a hollow structure and the top thereof has the opening. In the present invention, gas inlet 121 is disposed at the bottom of connecting base 12, and the top of connecting base 12 is communicated with the hollow structure of outer tube 13, and turbine assembly 20 is mounted above connecting base 12, so that gas can enter from gas inlet 121 and form a gas flow from bottom to top under the action of turbine assembly 20.

Thus, the gas entering through the gas inlet 121 is filtered by the filter element 14, and then forms a bottom-up gas flow by the action of the turbine assembly 20; in addition, the filter member 14 has an isolating and absorbing function for noise transmitted to the bottom direction of the fan 1, thereby reducing noise generated when the fan 1 operates.

In the present invention, the filter element 14 is made of a flexible material, such as a sound-absorbing sponge, but not limited thereto.

Referring again to fig. 3-4, the air suspension fan 1 of the present invention further includes a spacer 50, the spacer 50 has a shape corresponding to the shape of the outer tube 13 and is disposed closely to the inner wall of the outer tube 13, a gap is formed between the spacer 50 and the flow guide 30, the gap is greater than the thickness of the extension tube 40, and the extension tube 40 is movably disposed between the flow guide 30 and the spacer 50. The insulator 50 serves to absorb and insulate noise generated when the turbine assembly 20 operates, thereby making the aero-levitation fan 1 less noisy.

3-4 and 6-7, the isolation member 50 is connected to the bottom of the flow guide member 30, a gap between the two forms a passage for the telescopic tube 40 to move up and down, and the top of the flow guide member 30 protrudes out of the isolation member 50; when the telescopic tube 40 is in the first position, the bottom thereof abuts against the bottom of the partition 50 connected to the deflector 30.

In the present invention, the bottom end of the flow guiding member 30 has a step-shaped bearing portion 31, and a gap between the flow guiding member 30 and the spacer 50 under the bearing portion 31 forms a locking groove 32, as shown in fig. 4 and 7. Meanwhile, a shoulder 42 corresponding to the bearing portion 31 is disposed at the bottom end of the telescopic tube 40, when the telescopic tube 40 is at the first position, the shoulder 42 abuts against the bearing portion 31, and the bottom end of the telescopic tube 40 is engaged with the inside of the locking slot 32 and abuts against the bottom surface of the locking slot 32, as shown in fig. 4.

In addition, the bottom of the outer wall of the spacer 50 is provided with a notch 51, the inner wall of the outer tube 13 is provided with a protruding portion (not shown) corresponding to the notch 51, when the spacer 50 and the diversion element 30 are installed, the spacer 50 is tightly attached to the inner wall of the outer tube 13, and the notch 51 on the spacer 50 is correspondingly clamped with the protruding portion on the outer tube 13, so that the spacer 50 is positioned.

More specifically, the partition 50 is integrally formed with the flow guide 30, and the partition 50 and the flow guide 30 are integrally formed by using a flexible material (e.g., a sound-absorbing sponge), so that both have a good noise reduction function and can well absorb noise generated when the turbine assembly 20 operates.

As shown in fig. 7, the flow guiding member 30 has a conical structure, i.e., the outer diameter of the flow guiding member 30 gradually increases from top to bottom, and the separating member 50 has a cylindrical structure, so that the gap between the two gradually decreases from top to bottom. When the telescopic tube 40 is installed outside the diversion member 30, the telescopic tube 40 moves up and down along the inner wall of the partition member 50, so that the distance between the telescopic tube 40 and the diversion member 30 is gradually reduced from top to bottom, and thus, the air flow guided out by the telescopic tube 40 flows from top to bottom along the gap between the telescopic tube 40 and the diversion member 30, and in the process, the gap is gradually reduced from top to bottom, so that the air flow can always keep a certain pressure in the flowing process, the pressure of the air flow at the lower end of the air outlet 41 is ensured to be approximately equal to the pressure at the upper end of the air outlet, and the air flow sprayed out of the air outlet 41 is more uniform.

As shown in fig. 3-4 and 10, the air-suspending fan 1 of the present invention further includes a mounting base 60 mounted above the support member 15 for mounting the turbine assembly 20. Specifically, the mounting seat 60 is provided with a mounting hole 61 corresponding to the shape of the turbine assembly 20, a through hole (not numbered) communicating with the mounting hole 61 is opened at the lower end of the mounting seat 60, and a supporting portion 62 is protruded from the exterior of the mounting seat 60. The mounting seat 60 is disposed on the supporting member 15, the outer wall of the mounting seat abuts against the inner wall of the outer tube 13, the turbine assembly 20 is embedded in the mounting hole 61, meanwhile, the bottom of the flow guiding member 30 and the bottom of the isolating member 50 abut against the supporting portion 62 of the flow guiding member, and the bottom of the flow guiding member 30 is clamped outside the turbine assembly 20, as shown in fig. 4.

Preferably, the mounting base 60 is integrally formed by a flexible material, for example, a sound-absorbing sponge, so that the mounting base 60 can absorb vibration and noise generated by the turbine assembly 20 during operation, and further reduce noise of the air suspension fan 1.

As shown in fig. 8 to 9, the turbine assembly 20 includes an impeller housing 21, an impeller 22 disposed in the impeller housing 21, and a motor (not numbered) connected to the impeller 22, and the motor drives the impeller 22 to rotate, thereby forming a bottom-up airflow. Other structures and operating principles of the turbine assembly 20 are well known to those skilled in the art and will not be described in detail herein.

Referring to figures 1-4 and 11-13, the telescopic tube 40 has a first position retracted into the outer housing 10 and a second position protruding out of the outer housing 10, and the air flow generated by the turbine assembly 20 drives the telescopic tube 40 from the first position to the second position. And when the telescopic tube 40 is located at the first position, the air outlet 41 thereon is located in the outer shell 10, as shown in fig. 1-2 and 4; when the bellows 40 is moved up to the second position, the air outlet 41 thereof is exposed from the outer casing 10, so that the air flow can be ejected through the air outlet 41, as shown in fig. 11-13.

Referring to fig. 3 and 6-7, a guiding structure extending along the height direction of the outer tube 13 is provided between the telescopic tube 40 and the outer tube 13 or between the telescopic tube 40 and the spacer 50 for guiding the movement of the telescopic tube 40; and a positioning structure is arranged between the telescopic tube 40 and the outer tube 13 or between the telescopic tube 40 and the partition 50 to position the telescopic tube 40 at the second position.

Preferably, the guiding structure is a groove and a rib which are arranged between the telescopic pipe 40 and the isolating piece 50 and are matched with each other, the rib is arranged on one of the telescopic pipe 40 and the isolating piece 50, the groove is arranged on the other of the telescopic pipe 40 and the isolating piece 50, and both the groove and the rib extend along the sliding direction of the telescopic pipe 40. Of course, the guiding structure is not limited to the groove and the rib, and other structures can be provided.

As shown in fig. 6 to 7, in the present invention, the inner wall of the partition 50 is formed with a groove 52 extending along the height direction thereof. Correspondingly, the outer wall of the telescopic tube 40 is convexly provided with a rib 43 corresponding to the groove 52, and the length of the rib 43 is smaller than the height of the telescopic tube 40, as shown in fig. 3. After the telescopic tube 40 is installed, the rib 43 is correspondingly engaged with the groove 52, so as to guide the telescopic tube 40 to slide up and down.

In the present invention, the positioning structure comprises a first flange disposed on the telescopic tube 40 and a second flange 131 disposed on the outer tube 13. Wherein the first flange protrudes from the outer wall of the telescopic tube 40, the second flange 131 protrudes from the inner wall of the outer tube 13, and when the telescopic tube 40 slides upwards to the second position, the first flange abuts against the second flange 131, thereby preventing the telescopic tube 40 from being separated from the outer tube 13.

Preferably, the first flange is the end of the rib 43 (as shown in fig. 13), and when the telescopic tube 40 is slid upward to the second position, the end of the rib 43 abuts against the second flange 131, so as to position the telescopic tube 40.

Referring again to figures 1-4 and 11-13, the air suspension fan 1 of the present invention further comprises a decorative member 70, the decorative member 70 being provided at the top of the bellows 40 and being either integrally formed with the bellows 40 or otherwise secured or removably attached to the top of the bellows 40. When the fan 1 is operated, the telescopic pipe 40 is lifted to the second position, so that the decoration piece 70 is at a relatively high position, and when the fan 1 stops operating, the decoration piece 70 is moved downwards to a relatively low position and still has decoration, so that the air suspension fan 1 has high ornamental value.

In a preferred form of the present invention, decorative member 70 is a globe integrally formed with telescoping tube 40 and located at the top of telescoping tube 40, the globe having a hollow structure with the interior of the globe communicating with the hollow structure of telescoping tube 40, i.e., the top of telescoping tube 40 is sealed by the globe. When the telescopic tube 40 is at the first position, the lower end of the telescopic tube 40 is clamped in the clamping groove 32 and abuts against the bottom surface of the clamping groove 32, the globe is at a position relatively close to the outer tube 13, when the telescopic tube 40 is lifted to the second position, the globe is lifted along with the telescopic tube, and the globe can be normally used no matter whether the air suspension fan 1 works or not and has a good decoration effect.

Further, the ratio of the telescopic tube 40 to the outer tube 13 can be set such that when the telescopic tube 40 is in the first position, the globe at the top thereof is just supported on the top of the outer tube 13 (see fig. 4) while the bottom thereof abuts against the bottom of the deflector 30. Of course, the proportions of the telescopic tube 40 and the outer tube 13 and the shapes and sizes of the outer tube 13 and the globe may be set as required so that the globe can be received in the outer tube 13 when the telescopic tube 40 is in the first position.

In the present invention, an isolation layer (not shown) is further provided on the inner surface of the globe, and the isolation layer is made of a flexible material, for example, a sound-absorbing sponge is provided on the inner surface of the globe, so that when the air current acts on the top of the globe, the generated vibration and noise are absorbed by the isolation layer, and the noise of the fan 1 is further reduced.

It will be appreciated that when the air suspension fan 1 is not provided with the decoration 70 or the decoration 70 is additionally fixed to the top of the telescopic tube 40, an isolation layer may be provided on the inner surface of the top of the telescopic tube 40 to reduce noise when the fan 1 is operated.

With the above description, the air suspension fan 1 of the present invention has the filtering member 14 and the mounting base 60 with good noise reduction effect at the bottom, the isolation layer at the top globe inner surface or the top of the extension tube 40, and the isolation member 50 at the side, so that the air suspension fan 1 has good noise reduction effect at the periphery by the sound absorption structure at the top, the bottom, and the side, thereby making the air suspension fan 1 have very small noise.

Referring to fig. 4-5 and 13 again, in the present invention, a driving mechanism 80 is further disposed between base 11 and connecting seat 12, and driving mechanism 80 is used for driving connecting seat 12 and outer tube 13 to rotate relative to base 11. Specifically, the driving mechanism 80 includes a motor 81 disposed on the connecting base 12 and a gear plate 82 (see fig. 4-5) disposed on the base 11 and engaged with the motor 81, and the motor 81 rotates relative to the gear plate 82 to drive the connecting base 12 mounted with the motor 81 to rotate synchronously, so that the outer tube 13 connected to the connecting base 12 rotates synchronously, and the outer tube 13 drives the isolating member 50, the telescopic tube 40 and the flow guiding member 30 to rotate synchronously, and the swing function of the fan 1 is realized due to the rotation of the telescopic tube 40.

Meanwhile, due to the rotation of the extension tube 40, the globe arranged on the top of the extension tube 40 synchronously rotates along with the extension tube. Therefore, the globe on the top of the fan 1 can rotate all the time while the fan operates, and high ornamental and decorative effects are achieved.

The working principle and different usage states of the air suspension fan 1 will be described with reference to fig. 1-13.

Referring to fig. 1-2 and 4, when the air suspension fan 1 is in the first use state, the telescopic tube 40 is in the first position, the bottom end thereof is engaged in the slot 32 between the air guiding member 30 and the isolating member 50, the shoulder 42 abuts against the bearing portion 31, and the decoration member 70 disposed on the top thereof is borne on the top of the outer tube 13, thereby providing decoration and ornamental features.

When the turbine assembly 20 works, the turbine assembly 20 makes the air entering the outer tube 13 form an air flow from bottom to top, and the air flow is guided by the flow guide element 30 and then acts on the top of the telescopic tube 40 or acts on the top of the decorative element 70, so that the telescopic tube 40 rises under the action of the air flow, and the decorative element 70 rises along with the air flow; when the telescopic tube 40 moves to the second position, the first flange (i.e. the end of the rib 43) on the telescopic tube is abutted against the second flange 131 on the outer tube 13, as shown in fig. 13, so as to prevent the telescopic tube 40 from separating from the outer tube 13, and the air flow acts on the top of the telescopic tube 40 and then moves downwards under the guiding action of the telescopic tube 40, i.e. the air flow moves downwards along the gap between the telescopic tube 40 and the flow guide member 30 and then is ejected out through the air outlet 41 on the telescopic tube 40, thereby realizing the function of the fan 1. And because the flow guide member 30 is in a conical structure, the air flow moving downwards under the guiding action of the extension tube 40 can always keep a certain pressure, so that the air flow sprayed out from the air outlet 41 is uniform. Without stopping the turbine assembly 20, the extension tube 40 is always in the second position and the fan is always in operation, while the garnish 70 is always in a higher position, more ornamental, as shown in fig. 11-13.

Meanwhile, when the driving mechanism 80 operates, the motor 81 rotates relative to the toothed disc 82, so that the connecting base 12 provided with the motor 81 rotates therewith, the connecting base 12 drives the outer tube 13 to synchronously rotate relative to the base 11, and because the positioning structure is arranged between the outer tube 13 and the isolating piece 50, and the guide structure extending along the vertical direction is arranged between the isolating piece 50 and the telescopic tube 40, the outer tube 13 drives the isolating piece 50 and the telescopic tube 40 to synchronously rotate therewith, so that the decoration 70 at the top of the telescopic tube 40 generates a rotating effect, and the decoration and the interestingness are achieved.

When the turbine assembly 20 stops working, the bellows 40 loses the effect of the air flow and thus moves downwards under its own weight to the first position, as shown in fig. 1-2 and 4, which has a small volume and occupies a small space.

Because the air outlet 41 of the air suspension fan 1 is arranged on the extension tube 40, the extension tube 40 is movably sleeved between the flow guide member 30 and the outer shell 10, the turbine assembly 20 is utilized to form air flow from bottom to top, the flow guide member 30 is utilized to guide the air flow to act on the top of the extension tube 40, so that the extension tube 40 moves upwards to extend out of the outer shell 10 to expose the air outlet 41, and the extension tube 40 guides the air flow to the air outlet 41 and flows out; the user has cool wind feeling through continuous airflow, and the airflow is soft and stable; when the fan is not used, the turbine assembly 20 stops working to enable the telescopic pipe 40 to move downwards under the action of gravity, so that the fan 1 has a smaller volume and occupies a small space; meanwhile, any decoration 70 can be arranged on the top of the telescopic tube 40, and the fan 1 has higher ornamental value and decorative value while keeping the basic function thereof by means of the extension and retraction of the telescopic tube 40; in addition, the air suspension fan 1 is simple in structure, concise in appearance and convenient to clean.

The above disclosure is only for the preferred embodiment of the present invention, and it should be understood that the present invention is not limited thereto, and the invention is not limited to the above disclosure.
