[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings, and the above-mentioned and other objects, features, aspects and advantages of the present invention will become more obvious, so that those skilled in the art can implement them according to the description.
[0039] In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like components.

In particular, "height" is equivalent to the dimension from top to bottom, "width" is equivalent to the dimension from left to right, and "depth" is equivalent to the dimension from front to back. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directions should not be interpreted as restrictive terms.
[0041] Terms related to attachment, coupling, and the like (eg, "connected" and "attached") refer to either a fixed or attached relationship between structures, either directly or indirectly, and either movable or rigid attachments or relationships, unless expressly stated otherwise, of the structures to one another through intermediate structures.
[0042] According to one embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown in the figure, it can be seen that the guide lining structure includes:
[0043] The front shell 110 has a ring shape in the middle, with a height greater than a width, and includes two vertical sections 114 and two curved sections 113;
[0044] A rear shell 120 whose shape and size match those of the front shell 110 , and the front shell 110 and the rear shell 120 are combined to form an air duct 115 located therebetween and having an air inlet; and
[0045] The nozzle 111 is provided on the front shell 110 and / or the rear shell 120 so that the air duct 115 is connected to the outside through the nozzle 111.
[0046] Reference Figure 4 , Figure 5 , wherein a nozzle liner 131 opposite to the nozzle 111 is provided in the air duct 115 , so that each nozzle 111 is arranged to receive air from a corresponding one of the nozzle liner 131 .
[0047] Reference Figure 6 The nozzle liner 131 includes a left liner 1311 and a right liner 1312 that are opposite and spaced apart to form a space between the left liner 1311 and the right liner 1312. Figure 3 The guide air duct 133 is connected to the nozzle 111.
[0048] The guide air duct 133 is provided with guide plates 132 opposite to the nozzle 111 at intervals, so that the guide air duct 133 is divided into a left guide air duct 1331 and a right guide air duct 1332 by the guide plates 132 .
[0049] The nozzle liner 131 is described in more detail. The nozzle liner 131 is V-shaped as a whole. The angle formed by the nozzle liner 131 is smaller than the angle of the front shell 110. Figure 6 As shown, the nozzle liner 131 is formed by the intersection of the left liner 1311 and one end of the right liner 1312. Figure 7 Air outlets 1315 are provided at intervals at the intersection of the left lining plate 1311 and the right lining plate 1312 , wherein the number, shape and position of the air outlets 1315 are consistent with those of the nozzles 111 .
[0050] According to Figure 8 , Fig. 9 As shown in the figure, it can be seen that the guide plate 132 includes a guide front portion 1321 and a guide rear portion 1322, and the guide plate 132 is preferably in a water drop shape, and the guide plate 132 is connected to the nozzle front portion through the nozzle liner 131;
[0051] A flow guiding groove 13211 is provided on a surface of the flow guiding front portion 1321 facing the flow guiding rear portion 1322;
[0052] The surface of the flow guiding rear portion 1321 facing the flow guiding front portion 1321 is provided with a flow guiding flange 13221;
[0053] Among them, the guide flange 13221 is used in conjunction with the guide groove 13211. Preferably, the guide front part 1321 and the guide rear part 1322 are solid. Because the guide plate 132 is hollow inside and is spliced by the guide front part 1321 and the guide rear part 1322, gaps will be generated, which will generate noise. If the guide plate 132 is solid, the noise can be reduced.
[0054] The cross section of the guide plate 132 is in the shape of a water drop;
[0055] Wherein, the major axis of the cross section of the guide plate 132 is Figure 7 The central axes of the air outlets 1315 are shown to be collinear.
[0056] At least one side of the guide plate 132 is provided with a protruding flow guide hole 13222; the inner side of the nozzle liner 131 is provided with a liner through hole, the number and position of the liner through holes are consistent with the flow guide holes 13222, and the liner through holes are fixedly connected with the flow guide holes 13222 through the through holes.
[0057] In a specific embodiment, when the outside air flows into the bladeless fan, the driving device inside the bladeless fan drives the air flow to flow upward into the air duct 115 formed by the front shell 110 and the rear shell 120. Since the nozzle liner 131 is provided in the vertical section 114 of the front shell 110, which is V-shaped, the air flows in from the large opening of the V and is discharged from the small opening. The nozzle liner 131 is provided to avoid the whistling and noise caused by the roughness and roughness of the front shell 110. In addition, due to the The guide front portion 1321 and the guide rear portion 1322 are combined into a closed guide surface, and a left guide air duct 1331 and a right guide air duct 1332 are formed between the guide surface and the front portion of the nozzle 111 and the nozzle liner 131. Because the nozzle liner 131 is V-shaped, the left guide air duct 1331 and the right guide air duct 1332 are continuously reduced along the direction of movement of the air flow, thereby reducing the sound pressure level of the whole machine noise, making the wind softer, and improving the user experience. The guide surface makes the airflow ejected from the nozzle 111 a mixture of airflows in at least two directions.
[0058] Because the angle of the nozzle liner 131 is smaller than that of the front shell 110, the internal space of the air duct 115 becomes smaller. When the air flow enters the air duct 115 at a high speed, a pressure difference is generated, making the air flow discharged from the bladeless fan stronger, thereby accelerating the discharge of the air flow.
[0059] like Figure 7 As shown, at least two hooks 1313 are provided between the air outlets 1315, and the cross-sectional area of the hooks 1313 gradually decreases along the protruding direction thereof; a slot 1317 is formed between the hooks 1313, wherein the slot 1317 is adapted to the spacing structure 112 between the nozzles 111 spaced apart in pairs, wherein the slot 137 is adapted to the spacing structure 112 between the nozzles 135 spaced apart in pairs, so that the nozzle liner 131 is further fixed to the front shell 110 while being fixed by the locking structure 1314, thereby improving its stability and increasing the service life of the nozzle liner 131.
[0060] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.
[0061] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and implementation modes.
