[0033] The technical solutions of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0034] Figure 1 is a schematic diagram of the overall structure of the bladeless fan shown in the embodiments of the present utility model;

[0035] Figure 2 is an exploded view of the running - horse lamp assembly 3 shown in the embodiments of the present utility model;

[0036] Figure 3 is a schematic diagram of the structure of the running - horse lamp assembly 3 shown in the embodiments of the present utility model.

[0037] Please refer to Figures 1 to 3 , a bladeless fan provided by the embodiments of the present utility model includes a base 1 for supplying air, a fan head 2 for discharging air, and a running - horse lamp;

[0038] The top end surface of the base 1 is provided with a receiving groove 11, and the receiving groove 11 has an electricity - connecting contact surface;

[0039] The running - horse lamp assembly 3 includes a circuit board 30 and a plurality of RGB lamp beads 31. The plurality of RGB lamp beads 31 are evenly distributed on the circuit board 30, and the circuit board 30 can be connected to the base 1 through the electricity - connecting contact surface.

[0040] Specifically, after the running - horse lamp assembly 3 is installed in the receiving groove 11 and contacts the electricity - connecting contact surface of the receiving groove 11, conduction is achieved. When the bladeless fan is started, the base 1 supplies power to the circuit board 30, and the plurality of RGB lamp beads 31 can emit light according to a preset program, realizing the change of light effects of multiple different colors, thereby improving the recognition rate of the bladeless fan in a soft - light or light - less environment, facilitating the user to observe the location of the bladeless fan, and then smoothly approaching the bladeless fan for operation or avoiding the bladeless fan. The RGB lamp bead 31 is a lighting device composed of LED chips of three colors: red, green, and blue, and can realize different color changes and mixtures by controlling the brightness of the three colors, achieving the output of light effects of multiple colors.

[0041] In a possible implementation, the above bladeless fan further includes a monochromatic light 4, which is disposed on the side wall of the base 1. The monochromatic light 4 is adjacent to the control button 13 of the base 1, and the irradiation direction of the monochromatic light 4 faces the control button 13. In practical applications, in order to facilitate users with limited mobility to operate the bladeless fan smoothly, the control button 13 is installed at the bottom of the base 1, so that people with limited mobility can save the need to bend down to operate and realize the control of the bladeless fan by stepping on it with their feet. Therefore, in a low-light or no-light environment, the monochromatic light 4 provided on the side wall of the base 1 gives the user an indication direction to facilitate operation by stepping on it with their feet.

[0042] In a possible implementation, the above running light assembly 3 of the bladeless fan further includes a lamp cover 32 and a wire.

[0043] A wire hole is provided on the side wall of the lamp cover 32.

[0044] The first end of the wire is connected to the circuit board 30. The second end of the wire passes through the wire hole, and the end face of the second end forms a conductive contact surface. When the conductive contact surface is connected to the power connection contact surface, the circuit board 30 is connected to the base 1. Specifically, the power connection contact surface in the accommodation groove 11 can be arranged in the form of a conductive spring or a conductive elastic sheet. After the lamp cover 32 is embedded in the accommodation groove 11, the wire connected to the circuit board 30 passes through the wire hole of the lamp cover 32 and thus contacts and abuts against the conductive spring or the conductive elastic sheet.

[0045] In a possible implementation, the above lamp cover 32 of the bladeless fan includes a first frame 321 and a second frame 322. The first frame 321 and the second frame 322 are overlapped to form a chamber for accommodating the circuit board 30, and the circuit board 30 is arranged in a frame structure.

[0046] In a possible implementation, for the convenience of quickly assembling the running light assembly 3, please refer to Figure 2 and Figure 3 , the lamp cover 32 of the above bladeless fan is connected to the base 1 by a buckle, and the first frame 321 and the second frame 322 are connected by a buckle. With this arrangement, the overall assembly effect of the bladeless fan can be improved, and it is convenient to replace or maintain the running light assembly 3.

[0047] In a possible implementation, the above running light assembly 3 of the bladeless fan further includes a bracket 33, a first damping rotating shaft 34 and a second damping rotating shaft 35. The bracket 33, the first damping rotating shaft 34 and the second damping rotating shaft 35 are all arranged in a hollow structure.

[0048] The bracket 33 is connected to the side wall of the accommodating groove 11 through the first damping shaft 34; the second damping shaft 35 passes through the wire hole and is connected to the middle part of the bracket 33, and the wire passes through the second damping shaft 35, the bracket 33 and the first damping shaft 34 in sequence, and the wire forms the conductive contact surface at the end of the first damping shaft 34.

[0049] like Figure 4 and Figure 5 As shown, in a specific implementation, the user can rotate the bracket 33 to lift the bracket 33 from the accommodating groove 11, and fix the rotation angle of the bracket by the first damping shaft 34, and then rotate the lampshade 32 to change the relative angle of the lampshade 32, and use the second damping shaft to fix the rotation angle of the lampshade, thereby adjusting the light output angle of the RGB lamp bead 31 to achieve light output requirements at multiple angles.

[0050] In a possible implementation, the first damping shaft 34 of the bladeless fan includes a first shaft 340 and a plurality of stacked washers 341 and damping washers 342, wherein the plurality of stacked washers 341 and damping washers 342 are sleeved on the first shaft 340, and the bracket 33 and the base 1 can rotate relative to each other to squeeze the washers 341 and damping washers 342; the first shaft 340 is a hollow rod. Specifically, by sleeved washers 341 and damping washers 342 on the first shaft 340 and the second shaft, when the washers 341 and damping washers 342 are rotated under force, the washers 341 and damping washers 342 rotate synchronously, and the friction force generated by the movement of each damping washer 342 relative to the washers 341 ensures that the bracket 33 and the lampshade 32 can maintain a fixed effect at various angles during the rotation process.

[0051] In this embodiment, the arrangement direction of the second damping shaft is the same as that of the first shaft, and will not be described in detail herein.

[0052] In a possible implementation, a side wall of the accommodating groove 11 of the bladeless fan extends outward to form a groove (not shown) for moving the bracket 33; the RGB lamp beads 31 are seven-color lamp beads. In specific applications, the groove can facilitate the user's hand to touch the lampshade and lift it.

[0053] Compared with the prior art, the bladeless fan provided by the utility model can allow users to quickly locate the bladeless fan through the light effect emitted by the marquee assembly 3 in a weak light or no light environment, making it convenient for users to approach the property fan to operate it, or walk around the bladeless fan to avoid being tripped by the bladeless fan and falling.

[0054] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary skill in the art to understand the embodiments disclosed herein.
