[0057] Example 1

[0058] See also Figure 1-Figure 4 In this embodiment, an air outlet component includes:

[0059] The hollow housing 1 is provided with an air inlet 11 and an air outlet 12 which are arranged opposite to each other;

[0060] The assembly platform 13 is disposed in the inner cavity of the hollow shell 1 and is capable of forming an annular air duct 14 with its inner wall, and the air inlet 11 realizes air convection with the air outlet 12 through the annular air duct 14;

[0061] The fan blade structure 15 is disposed at one end of the assembly platform 13 close to the air inlet 11;

[0062] A negative ion generator 2, comprising a generator body 21 and a negative ion emission head 22 which are electrically connected;

[0063] The negative ion cabin 3 is detachably fixed to one end of the assembly platform 13 close to the air outlet 12, and a communicating slot 31 and a through hole 32 are provided at the inner end. The generator body 21 is adapted to the slot 31, and the discharge end of the negative ion emission head 22 passes through the through hole 32, and its end extends to the side close to the air outlet 12.

[0064] The working principle of this embodiment is as follows: first, the generator body 21 is used to increase the DC low voltage (DC 5V) to a DC negative high voltage (DC-2.9~-3.4KV), and the negative ion emitter 22 generates a high corona to ionize the air, releasing a large number of electrons that are captured by oxygen molecules in the air to form negative ions, which escape from the air outlet 12 through the perforations 32, and then the fan blade structure 15 is used to make the air inlet 11 and the air outlet 12 realize air convection, and diffuse the negative ions located at the air outlet 12 into the indoor space. The concentration of negative ions that can be generated by this embodiment is: (2.2~2.6)×10 6 PCS / cm3. This increases the concentration of negative ions in the air and achieves the function of purifying the air, which is conducive to meeting more usage needs and broadening the application scenarios of the air outlet components.

[0065] Preferably, it also includes:

[0066] The high voltage line 23 can pass through the through hole 32, the input end is electrically connected to the generator body 21, and the output end is connected to the negative ion emission head 22;

[0067] A first power supply line 24 has a lead hole on the assembly platform 13 , an input end passes through the lead hole and is electrically connected to a power source, and an output end is electrically connected to the generator body 21 .

Since the blades will rub against the air when rotating and will carry static electricity on the blades, especially when the negative ion emitter 22 is working, the negative ions diffuse into the indoor space and will make the dust, pollen, dander and other particles in the air charged. The charged particles are easily attached to the statically charged blades, resulting in the cleaning frequency of the blades being higher than that of the blades of conventional fans. The present embodiment uses an antistatic coating to reduce the situation where charged particles adhere to the blades, which is beneficial to improving the cleanliness of the blades and reducing the cleaning frequency.

[0077] Preferably, it also includes:

[0078] The second rib is disposed on the through hole 32. The negative ion emitter 22 is a carbon brush head. The second rib acts on the carbon brush head and enables the carbon brush head to be suspended above the air outlet 12. Further, the safety of use is improved.

[0079] Preferably, it also includes:

[0080] A buckle, arranged at the inner end of the negative ion capsule 3;

[0081] The buckle position is arranged at one end of the assembly platform 13 close to the negative ion capsule 3 and can be matched with the buckle. The structure is simple and easy to assemble.
