Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides an air outlet assembly 1, which includes a housing 11, a fan 12 and a first air outlet 113. Casing 11 has the first uncovered 112 and the second uncovered 113 of inner chamber 111 and intercommunication inner chamber 111, and in the cavity was located to fan 12, the air-out side of fan 12 corresponded first uncovered 112 and laid, and the air-in side of fan 12 corresponds second uncovered 113 and lays, and casing 11, and intercommunication inner chamber 111 are worn to locate by first exhaust vent 113.

Above-mentioned air-out subassembly 1, when actual operation, air-out subassembly 1 can install in electrical equipment's air outlet department. When the fan 12 rotates, air (and/or water mist) in the electrical equipment is drawn into the inner cavity 111 through the second opening 113 and discharged out of the inner cavity 111 through the first opening 112, and finally discharged into the environment; meanwhile, when the fan 12 rotates, because the inner cavity 111 is communicated with the inside of the electrical equipment through the first air outlet 113, air (and/or water mist) in the electrical equipment can be sucked into the inner cavity 111 through the first air outlet 113, and is discharged out of the inner cavity 111 through the first opening 112, and finally discharged into the environment.

Compared with the prior art, the circulation path of the air (and/or the water mist) is increased, the exhaust air quantity of the fan 12 in unit time is increased, the exhaust speed of the air (and/or the water mist) is increased, and the efficiency of the fan 12 is improved under the condition that the size and the power of the fan 12 are not increased.

It can be understood that the air outlet side of the fan 12 is disposed corresponding to the first opening 112, and the air inlet side of the fan 12 is disposed corresponding to the second opening 113, that is, the air discharge direction of the fan 12 is toward the first opening 112.

Preferably, the number of the first air outlet holes 113 is multiple, and the multiple first air outlet holes 113 are arranged around the fan 12. Therefore, air circulating through the first air outlet can enter the inner cavity 111 from all directions, and the operation stability of the equipment is maintained.

Specifically, in the embodiment, referring to fig. 2 and 3, the air outlet assembly 1 further includes a nozzle 13 protruding from the inner wall of the housing 11, the nozzle 13 has a first port 131 and at least one second port 132 communicating with the first port 131, the first port 131 of the nozzle 13 is disposed on the inner wall of the housing 11 and communicates with the first air outlet 113, and the second port 132 of the nozzle 13 protrudes toward the first opening 112.

In actual operation, the rotation of the fan 12 causes the inner cavity 111 to form a negative pressure, and under the action of the negative pressure, part of the air (and/or water mist) enters the nozzle 13 through the first port 131, and then is divided by the second port 132 to be ejected toward the first opening 112 along different directions. Therefore, the flow path of the air (and/or the water mist) is increased, the air (and/or the water mist) can be divided into a plurality of strands to be sprayed out along all directions, the movement direction of the air (and/or the water mist) discharged through the first opening 112 is dispersed in the environment along all directions, the water mist can fill the whole environment more easily, and the humidity balancing process of all places of the whole environment is accelerated.

In this way, the nozzle 13 is in the form of a fork, which enables the air ejected by the nozzle 13 to move in multiple directions, accelerating the diffusion of the air (and/or water mist) in the environment.

Further, openings for communicating the first port 131 with the second port 132 are provided in the main flow path and the branch flow path, and the air introduced into the head 13 through the first port 131 can be ejected from the openings, thereby further increasing the ejection direction of the air.

In some embodiments, referring to fig. 4, the fan 12 includes a fan blade 121 and a second air outlet 125 disposed on the fan blade 121, wherein the second air outlet 125 penetrates from the windward side of the fan blade 121 to the leeward side of the fan blade 121. In actual operation, when the fan blade 121 rotates, when air (and/or water mist) entering through the second opening 113 reaches the fan blade 121, a part of the air (and/or water mist) moves towards the first opening 112 through the trailing edge of the fan blade 121, and the other part of the air (and/or water mist) moves towards the first opening 112 through the second air outlet 125 on the fan blade 121, so that the air (and/or water mist) discharged through the first opening 112 can be discharged towards different directions, and the diffusion of the air (and/or water mist) in the environment is accelerated, so that the air (and/or water mist) can more quickly fill the whole environment, and the problem of poor user experience caused by the concentrated discharge of the air (and/or water mist) towards one direction is avoided.

The end cover 122 has a third air outlet 126, and the third air outlet 126 communicates with the second opening 113 and the first opening 112.

During the process that the motor drives the rotating shaft 123 to rotate, the end cap 122 and the fan blades 121 rotate along with the rotating shaft. In practical operation, after the fan blade 121 rotates to drive air (and/or water mist) to enter the inner cavity 111 through the second opening 113, a part of the air (and/or water mist) moves towards the first opening 112 through the third air outlet 126, and is discharged in different directions under the guidance of the third air outlet 126. Therefore, the third end cover 122 can be prevented from blocking the movement of air (and/or water mist), the movement of the air (and/or water mist) in the inner cavity 111 is accelerated, and the movement direction of the air (and/or water mist) exhausted through the first opening 112 is increased, so that the exhaust angle range of the air outlet assembly 1 is wider, the air (and/or water mist) can be accelerated to diffuse in the environment, and the comfort level of a user is improved.
