[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work fall within the protection scope of the present invention.

[0047] In the drawings, for clarity, the shapes and dimensions may be enlarged, and the same reference numerals will be used throughout the figures to indicate the same or similar components.

[0048] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined with respect to the structures shown in the respective drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientations should not be construed as restrictive terms.

[0049] Terms related to attachment, connection, etc. (e.g., "connected" and "attached") refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as a movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0050] According to an embodiment of the present invention in combination with Figure 1 , Figure 2 and Figure 3 as shown, it can be seen that the impeller lead-out structure includes:

[0051] A base 1 with a hollow interior, forming an accommodation space; an air flow generator 2; which is arranged in the accommodation space formed by the filtering device 1; a diverter 3, which is arranged directly above the air flow generator 2.

[0052] Wherein, a first lead hole 232 is provided on the air flow generator 1, a second lead hole 3231 is provided on the bottom surface of the diverter 3, and the base 1, the air flow generator 2 and the diverter 3 are coaxially arranged in sequence from top to bottom.

[0053] According to Figure 4As shown, it can be clearly seen that the diverter 3 includes a first member 31 with a hollow interior; a second member 32 with a recessed interior and coaxially disposed above the first member 31; wherein, at least two annular diversion openings 322 are provided at the upper end of the second member 32, and the first member 31 and the second member 32 are oppositely disposed to form a diversion space.

[0054] The annular diversion openings 322 are closely attached to the air duct 4, and a sealing ring is further provided around the annular diversion openings 322 to ensure that the air flow in the diversion space does not leak out, thereby improving the strength of the air flow.

[0055] Reference Figure 5 shows that a second skirt 321 extends downward from the middle of the second member 32, and a partition 323 is provided inside the second skirt 321; wherein, the partition 323 is integrally formed with the second skirt 321 and divides the second skirt 321 into an upper skirt 3211 and a lower skirt 3212, and a second lead hole 3231 is provided on the partition 323.

[0056] The first lead hole 232 and the second lead hole 3231 are arranged with the maximum displacement in the horizontal direction, so as to increase the path of the circuit and reduce the occurrence of circuit winding.

[0057] Now referring to Figure 6 which details that the air flow generator 2 includes: a power chamber 25 that provides kinetic energy for generating high-speed air flow, and an impeller driver 251 is provided inside the power chamber 25, and the impeller driver 251 is connected to the control panel 22; a diversion pipe 22 with a hollow interior and both upper and lower ends open to form an upper opening and a lower opening respectively; an impeller 24 coaxially disposed below the power chamber 210, and the power output end of the impeller driver 251 is drivingly connected to the impeller 24, so that the impeller 24 rotates around the axis of the diversion pipe 22 under the drive of the impeller driver 251;

[0058] The diversion pipe 22 has a hollow interior and both upper and lower ends are open to form an upper opening and a lower opening respectively;

[0059] The circuit chamber 21 has a hollow interior and is disposed between the second member 31 and the power chamber 25;

[0060] Wherein, the power chamber 25 and the impeller 24 are disposed inside the diversion pipe 22 and form an annular diversion cavity 231, and the cross-sectional area of the circuit chamber 21 gradually decreases along the air flow direction.

[0061] The upper end surface of the circuit chamber 21 is provided with a lead hole 211, and the lead hole 211 is arranged directly below the second lead hole 3231 and is in close connection with the second lead hole 3231; a flange 212 is also provided, and the flange 212 is adapted to the lower skirt 3212. The flange 212 and the lower skirt 3212 are alternately fitted to form a sealed state between the second member 31 and the lead chamber 21, preventing the air flow in the air duct 4 from entering the lead chamber 21, which may cause noise, poor air outlet effect, high energy consumption, and reduced user experience.

[0062] Now in combination with Figure 9 , referring to Figure 7 and Figure 8 , it can be noted that load-bearing columns 212 and rib plates 213 are arranged at intervals inside the circuit chamber 21, and the rib plates 213 are integrally formed with the circuit chamber 21. Now referring to Figure 10 and Figure 11 , it can be clearly understood that a support ring 26 is also provided below the circuit chamber 21. Arc-shaped grooves 262 are arranged at intervals in the inner circle of the support ring 26, and the arc-shaped grooves 262 are adapted to the load-bearing columns 212. A snap flange 261 extending radially outward is provided at the bottom of the support ring 26.

[0063] Now in combination with Figure 12 , referring to Figure 13 , it can be clearly understood that a sealing ring 27 is provided below the circuit chamber 21. The sealing ring 27 is preferably made of rubber. A clamping groove 272 is provided in the inner circle of the sealing ring 27, and the clamping groove 272 is adapted to the snap flange 261. At least two protrusions 273 are provided on the bottom surface of the sealing ring 27, and a clamping claw 271 extending radially downward is provided on its outer circle.

[0064] In combination with Figure 13 , referring to Figure 6 again, it can be clearly seen that in the specific embodiment, the bottom end of the sealing ring 27 is in close contact with the upper end surface of the air flow generator 2. Since the sealing ring 27 is provided with clamping claws 271, the gap between the circuit chamber 21 and the air flow generator 2 is filled to form a sealed space. When the protrusions 273 at the bottom of the sealing ring 27 are subjected to the pressure of the circuit chamber 21 and the diverter 3, they will deform downward, enabling more surfaces to contact the upper end surface of the air flow generator 2. On the one hand, it plays a buffering role, and on the other hand, the air between two adjacent protrusions 273 is squeezed out, enhancing the fixation of the sealing ring 27 on the air flow generator 2 and preventing it from easily detaching from the air flow generator 2, thereby enhancing the tightness.

[0065] The rib plate 213 is in close contact with the upper end surface of the sealing ring 27 to strengthen the strength of the outer wall of the wiring chamber 21. The support ring 26 adapted to the sealing ring 27 is adapted to the load-bearing column 212 to enhance the strength of the middle part of the wiring chamber 21. The support ring 26 is provided in a ring shape to reduce the cost while ensuring the supporting effect, and another purpose is to provide more wiring storage space in the wiring chamber 21.

[0066] According to Figure 14 As shown, it can be clearly seen that a main board bracket 11 is provided on the base 1, and a main board 12 is installed on the main board bracket 11. The overall height of the main board 12 can cover the lowest part of the second component 32 of the shunt 3.

[0067] In the specific implementation, the circuit starts from the impeller driver 251 in the power chamber, passes through the control panel 22, sequentially passes through the first lead hole 232, the lead hole 211, and the second lead hole 3231, and finally is connected to the main board 12; the main board 12 controls the control panel 22, thereby controlling the impeller driver 251, further controlling the impeller 24, and finally controlling the wind speed of the bladeless fan, so that the circuit can be connected to the main board without passing through the air duct, avoiding the phenomenon of uneven air flow caused by the circuit passing through the air duct, further improving the smoothness of the air flow, and reducing noise.

[0068] In the preferred implementation, the outlet direction of the circuit is not specified on the top surface of the air flow generator, and it can be the side surface or the bottom surface; parts can be used to wrap the circuit, which can protect the circuit and also enable the circuit to pass through the air duct; some guide vanes are thickened so that the circuit passes through the inside of the guide vanes. It should be understood that the part of the guide vanes should be fixed inside the bladeless fan to prevent the circuit from winding.

[0069] The number of devices and the processing scale described here are used to simplify the description of the present invention. The application, modification, and variation of the present invention are obvious to those skilled in the art.

[0070] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made.
