Inside, the driving device 3250 is in transmission connection with the gear set 3240.

The upper end surfaces of the fixed layer 3230 and the rotating layer 3220 are provided with a straight partition 3231 and a circumferential partition 3221 spaced apart;

Wherein, the straight partition 3231 is radially formed from the center of the fixed layer 3230 and the rotating layer 3220 in the radial direction;

The circumferential partition 3221 is concentric circles in the radial direction;

The straight baffle 3231 and the circumferential baffle 3221 are intersected in the same plane to form a mesh barrier. The barrier not only ensures the strength of the structure, but also saves materials and provides a certain degree of waterproofing. effect.

A base baffle 3210 is provided on the periphery of the fixed layer 3230 and the rotating layer 3220;

Wherein, the base baffle 3210 wraps the fixed layer 3230 and the rotating layer 3220, the base baffle 3210 is provided with a switch button 3211, and the surface of the fixed layer 3220 facing the ground is arranged in a circular array. The supporting feet are used to support the bladeless fan without direct contact with the ground, so that the bladeless fan is more stable.

The gear set 3240 is sleeved on the rotating layer 3220;

The rotating layer 3220 has a hollow center and extends to both sides to form a hollow cylinder 3222, and the gear set 3220 is arranged in cooperation with the hollow cylinder 3222.

A supporting column 3241 is provided on the gear set 3240;

The support column 3241 is provided with at least part of a spring, the end of which is a smooth round head, and the support column 3241 is provided with a part of the spring that can move in the axial direction as the driving device 3250 generates vibration in the axial direction. Move up and down to relieve the vibration in the axial direction caused by the driving device 3250.

Referring now to FIG. 16, it can be seen that the surface of the large gear of the gear set 3240 facing the fixed layer 3230 is provided with smooth grooves 24 arranged in a circular array;

The edge of the base surface 340 is tightly combined with the bottom edge of the filter structure 310 of the bladeless fan, and the side of the filter structure 310 is provided with meshes arranged in an array. The mesh at the end is sparse, which is due to the fact that under the action of the driving device inside the filter structure, the suction force of the air in the middle of the filter structure is relatively large, and the suction force at the upper and lower ends is weak, so there is no need to open more meshes, which saves materials; The filter structure 310 also has a certain supporting effect on the bladeless fan, and the sparse meshes at the upper and lower ends ensure the pressure strength of the filter structure 310.

An air intake space 3310 is formed between the base surface 340 and the rotating base device 320, so the filter structure 310 of the bladeless fan does not directly contact the rotating base device 320, and the outside air flow enters through the air intake space 3310 Because the driving device 3250 is partially exposed to the air intake space 3310, under the action of the air flow, part of the heat generated by the driving device 3250 can be taken away, the temperature is reduced, and the driving device 3250 is increased.

The bladeless fan can be driven to rotate as a whole.

According to an embodiment of the present invention in combination with the illustrations in Figs. 17 and 18, it can be seen that the air flow generating structure includes:

The filter member 410 is hollow inside to form an accommodation space; and

An air flow generating device 420, which is erected in the containing space of the filter member;

Wherein, the filter member 410 completely wraps the air flow generating device 420.

The curved side of the filter member 410 is provided with grids or grids in an array as a whole.

The air flow generating device 420 includes:

The drainage tube 4210 is hollow inside and both upper and lower ends are open to form an upper opening and a lower opening respectively;

The power chamber 4220 is spaced and coaxially arranged in the drainage tube 4210 to form an annular drainage cavity 4230 between the drainage tube 4210 and the power chamber 4220.

The annular drainage cavity 4230 is provided with a rotating impeller 4240 coaxially arranged with the drainage tube 4210, and an impeller driver 4250 is provided in the power chamber 4220. The power output end of the impeller driver 4250 is connected to the rotating impeller. The 4240 is in a transmission connection, so that the rotating impeller 4240 is driven by the impeller driver 4250 to make a rotational movement around the axis of the drainage tube 4210.

The rotating impeller 4240 is arranged downstream of the airflow in the draft tube 4210.

A fixing assembly for fixing the power chamber 4220 is fixedly connected between the power chamber 4220 and the drainage pipe 4210, and the fixing assembly is arranged upstream of the airflow in the drainage pipe 4210.

The fixed assembly is at least two guide vanes 4260 fixed between the power chamber 4220 and the draft tube 4210. In a specific embodiment, the rotating impeller 4240 is located at the lower opening of the draft tube 4210. The guide vane 4260 is located at the upper opening of the draft tube 4210.

The guide vane 4260 can correct the flow direction of the airflow deflected after being driven by the rotating impeller 4240. The deflection direction of the rotating impeller 4240 makes the airflow flow clockwise or counterclockwise in a vortex. The deflection direction of 4260 is opposite to the deflection direction of the rotating impeller 4240, and the airflow rotating clockwise or counterclockwise is guided by the guide vane 4260 in the opposite deflection direction, so that the corrected airflow direction is the same as the deflection direction of the airflow. The axial direction of the drainage tube 4210 is consistent, which improves the smoothness of air flow and reduces the generation of noise.

Now referring to Figure 19, it can be seen that the guide vane 4260 includes an introduction section 4261 and an exit section 4262 arranged in sequence along the flow direction of the airflow. The radius of curvature of the introduction section 4261 is set so that the flow direction of the airflow before correction is consistent with the flow direction of the airflow. The tangent directions at the entrance of the lead-in section 4261 are consistent, and the radius of curvature of the lead-in section 4261 is smaller than the radius of curvature of the lead-out section 4262. The lead-in section 4261 and the lead-out section 4262 are in a smooth transition, which further solves the problem of air flow. The problem of noise caused by poor circulation.

The lower opening of the drainage tube 4210 is successively formed along the direction opposite to the air flow direction: a tapered section 4211, the cross-sectional diameter of which gradually decreases in the direction opposite to the air flow direction; and a tapered section 4212 , Its cross-sectional diameter is gradually expanding in the direction opposite to the direction of air flow. The overall cross-sectional area of the draft tube 4210 first gradually decreases along the flow direction of the airflow and then gradually expands. The divergent section 4212 has the advantage of enlarging the air intake, and a large amount of airflow gathers in the gradual Section 4212, because the intersection of the tapered section 4211 and the tapered section 4212 is the place where the interface diameter is the smallest. Before entering the diverging section 4212 or when entering the diverging section 4212, the airflow movement follows the principle of "when the fluid moves in the tube, the flow velocity is large at a small section, and the flow velocity is small at a large section", so the airflow continues to accelerate. When it reaches the narrow throat, the velocity has exceeded the speed of sound. The transonic fluid no longer follows the principle of "higher velocity at small cross-sections and low velocity at large cross-sections" when moving, but on the contrary, the larger the cross-section, the faster the velocity, which increases the flow velocity of the airflow entering the splitter 430. , Improve user experience.

In a specific embodiment, the air flow generating device 420 is completely placed in the containing space, and because the curved side of the filter member 410 is provided with grids or meshes arranged in an array, the air flow is increased. The air area increases the air purification area; there is no need to add a sealing device between the air flow generating device 420 and the filter member 410, so that the bladeless fan will not fail due to the missing installation or failure of the sealing device.
