Examples

Referring to fig. 1, fig. 1 shows an overall structural schematic diagram of a bladeless fan 10.

The bladeless fan 10 includes a fan body 100, a power mechanism 260, a first temperature sensor 210, an electric heating device 220, a second power supply 230, a second temperature sensor 240, a controller 250, and at least three telescopic brackets 310. The fan body 100 includes a base 110 and a head 120 mounted on the base 110, the base 110 is provided with a containing cavity 113, the power mechanism 260 is mounted in the containing cavity 113, the head 120 is annular, a blowing channel is formed inside the head 120, a blowing port is formed along the circumferential direction of the head 120, and an air flow generated by the power mechanism 260 flows through the blowing channel to blow out the blowing port to form an annular air flow.

In addition, referring to fig. 2 and fig. 3, a plurality of guiding elements 320 are installed inside the base 110, that is, the guiding elements 320 are all installed in the accommodating cavity 113, and the guiding elements 320 are fixed in the accommodating cavity 113 in the base 110. In this embodiment, at least three telescopic brackets 310 are provided, the number of the guide members 320 is the same as that of the telescopic brackets 310, and each guide member 320 is provided corresponding to each telescopic bracket 310.

Wherein, through-channel 321 has been seted up to guide 320, the through-hole 112 that communicates with through-channel 321 has been seted up to the bottom of base 110, through-channel 321 sets up along the direction of height of base 110, the inner wall of through-channel 321 is provided with rubber layer 322, telescopic bracket 310 includes support piece 311 and the handheld portion 312 of being connected with support piece 311, guide way 111 has been seted up to base 110, guide way 111 sets up along the direction of height of base 110, handheld portion 312 wears to locate guide way 111 and can move relative to guide way 111, support piece 311 is installed in through-channel 321, and support piece 311 can follow through-channel 321 and through-hole 112 relative slip, support piece 311 and the contact of rubber layer 322.

When a force is applied to the handle 312, the handle 312 can move relative to the guide slot 111, that is, the handle 312 moves along the height direction of the base 110, the handle 312 moves to drive the supporting member 311 to move along the through channel 321, and since the through channel 321 is also arranged along the height direction of the base 110, the supporting member 311 can also move along the height direction of the base 110. In the present embodiment, the holding portion 312 is rod-shaped, the supporting member 311 is rod-shaped, and the axis of the holding portion 312 is perpendicular to the axis of the supporting member 311. This arrangement can facilitate the application of force to the hand-held portion 312.

Because the inner wall of the through channel 321 is provided with the rubber layer 322, the supporting member 311 generates friction force when sliding, and only when the force is large enough, the supporting member 311 can slide out of the through channel 321 and the through hole 112, so that the supporting member 311 extends out to support the base 110. When no force is applied, the rubber layer 322 has elasticity and has a blocking effect on the supporting member 311, and the supporting member 311 cannot slide relative to the guiding member 320, so that the supporting member 311 cannot slide randomly when supporting the base 110 after the supporting member 311 slides out of the through passage 321 and the through hole 112, and the supporting stability is ensured.

Because each telescopic bracket 310 corresponds to one guide piece 320, the telescopic height of each telescopic bracket 310 can be controlled independently, and when the placing surface of the base 110 is uneven, the base 110 can be stable relative to the horizontal plane by adjusting the telescopic height of each telescopic bracket 310. In addition, when the telescopic bracket 310 forms a support for the base 110, the heat dissipation of the base 110 of the bladeless fan 10 is also facilitated. In addition, the telescopic bracket 310 of the present embodiment is provided with at least three, for example, three, four, or five, etc.

In this embodiment, the power mechanism 260 includes an electric motor and a first power supply device electrically connected to the electric motor, the electric motor draws air into the base 110, surrounds the handpiece 120, and drives the air near the handpiece 120 to enter the handpiece 120 and be ejected out through the air outlet at a high speed. The second power supply device 230 is electrically connected to the electric heating device 220, and the electric heating device 220 is disposed in the fan body 100 and is used for heating the air blown by the fan body 100. In the present embodiment, the electric heating device 220 is disposed inside the handpiece 120 and located at the air outlet of the handpiece 120, so that the wind blown out through the air outlet can be heated by the electric heating device 220 and then changed into hot wind.
