Detailed Description

The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, which will enable those skilled in the art to practice the present invention with reference to the accompanying specification.

In the drawings, the shape and size may be exaggerated for clarity, and the same reference numerals will be used throughout the drawings to designate the same or similar components.

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 configurations shown in the respective drawings, and in particular, "height" corresponds to a dimension from top to bottom, "width" corresponds to a dimension from left to right, "depth" corresponds to a dimension from front to rear, which are relative concepts, and thus may be varied accordingly depending on the position in which it is used, and thus these or other orientations should not be construed as limiting terms.

Terms concerning attachments, coupling and the like (e.g., "connected" and "attached") refer to a relationship wherein structures are secured or attached, either directly or indirectly, to one another through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.

According to an embodiment of the present invention, with reference to the illustrations of fig. 1 and fig. 2, it can be seen that the flow dividing structure includes:

a first member 10 having a hollow interior to form a connection space 111; and

a second member 20 recessed therein and coaxially mounted on the first member 10,

wherein, the second component 20 is provided with at least two annular diversion ports 210, the first component 10 is matched with the second component 20, and a diversion channel is formed between the first component 10 and the second component 20.

The first member is provided with a first curved member 110, the first curved member 110 wrapping the second member 20. At least four supporting parts 120 are arranged around the outer side of the first bending member 110, and are used for erecting the flow dividing structure inside the bladeless fan body. The first bending member 110 extends downward to form a connection part 130, and as can be seen from fig. 6, the connection part 130 is used for connecting the driving device 40 of the bladeless fan, so that the air flow in the body can smoothly enter the flow dividing structure 30.

Referring to fig. 3, 4 and 5, the second member 20 is provided with a second bending member 220, which is disposed opposite to the first bending member 110 to form a diversion space, and the at least two annular diversion ports 210 are disposed at an end of the second bending member 220. The air flow in the bladeless fan body enters the flow dividing structure 30 from the inner side of the fan body through the driving device 40, the air flow is separated to at least two annular ports 230 in a flow dividing channel of the flow dividing structure 30, the annular flow dividing ports 230 extend into and are tightly attached to the flow dividing channel 251, the air flow smoothly enters the flow dividing channel 251, the air flow is prevented from rapidly entering a long and narrow nozzle to form noise, and user experience is improved.

The bottom of the second bending member 220 is recessed downward to form a groove 230, and the groove 230 is disposed in the connecting space 111 formed by the first member 10. The groove 230 is internally provided with a convex block 240, the inside of the convex block 240 is an open space, the open space is provided with a motor device of the driving device 40, so that the inner space is further saved, the end face of the convex block 240 is provided with at least four supporting seats 241, the supporting seats 241 are used for supporting the shell of the sub-runner 251, the abrasion of the shell of the sub-runner 251 and the sub-runner structure 30 is reduced, and the service life of the sub-runner 251 is further prolonged.

The shape of subchannel 251 is changeable, has a plurality of angles, though annular subchannel 210 stretches into and hugs closely in subchannel 251, still can be because of the multi-angle of subchannel 251 produces the gap, follows the air current that annular subchannel 210 got into returns in the organism of bladeless fan, causes the problem that the air current intensity of ejaculating is not enough, still probably causes the noise, annular subchannel 210's periphery is equipped with sealing washer 252, has the multi-angle, inboard with annular subchannel 210 closely laminates, the outside with subchannel 251 closely laminates, can effectively block gaseous backward flow, prevents that the air flow from diffusing all around, has not only improved the intensity of air, has still reduced the noise, further improves user experience degree.

In a specific embodiment, the arrangement of the annular diversion ports 210 may be that at least two of the annular diversion ports 210 are arranged on the second member 20 side by side with an interval, or may be arranged in a circumferential array around the central axis of the second member 20; wherein the number of the first bending members 110 of the first member 10 and the second bending members 220 of the second member 20 is the same as the number of the annular diversion ports 210.

The number of apparatuses and the scale of the process described herein are intended to simplify the description of the present invention. Applications, modifications and variations of the present invention will be apparent to those skilled in the art.
