TECHNICAL FIELD

[0001] The present application relates to the fan technical field, especially to a spray fan. BACKGROUND

[0002] At present, the spray fan is widely used in the relatively dry environment, mainly through the fan blade rotation to generate airflow, and combines the atomizing device, diffuses the mist to the air, thereby plays the effect of increasing the air humidity and cooling. The spray fan generally includes a fan shell, a fan mechanism installed on the fan shell, an atomizing device installed on the fan shell, and a gas delivery pipe for delivering the mist produced by the atomizing device to the front side of the fan mechanism. The gas delivery pipe forms an air outlet on the front side of the fan mechanism. When the above-mentioned spray fan is running, the atomizing device atomizes the water mist into mist through high-frequency vibration, the mist is output from the air outlet through the gas delivery pipe, and the wind blown by the fan mechanism is delivered to the surrounding environment. For the above-mentioned related technology, the inventor believes that the amount of mist output from the air outlet is small, and the effect of diffusing the mist to the surrounding environment of the spray fan needs to be improved. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the effect of diffusing the mist output by the spray fan to the surrounding environment, the present application provides a spray fan.

At least one side of the air outlet channel is provided with a long strip-shaped mist outlet along the height direction. The fan shell is also provided with a mist outlet assembly for delivering the mist output by the atomizing device to the mist outlet.

[0006] By adopting the above technical scheme, the fan mechanism will form a high-speed airflow at the air outlet channel when running. According to Bernoulli's principle, the air pressure at the air outlet channel is low, so that the mist in the mist outlet assembly can be extracted through the mist outlet, which helps to make the spray range of the spray fan more ideal and improves the effect of diffusing the mist output by the spray fan to the surrounding environment.

[0009] Optionally, the length of the mist outlet is 60% to 95% of the height of the air outlet channel.

[0010] By limiting the length of the mist outlet and the proportion of the height of the air outlet channel, the amount of mist output by the mist outlet is ideal within the proportion range, and the effect of the mist fan output diffusing mist into the surrounding environment is further improved.

[0043] With reference to Figure 2 , Figure 4 andFigure 7 The side edge of the air outlet channel 13 is provided with a long strip-shaped mist outlet 131 in the height direction. The mist outlet 131 penetrates and communicates the installation chamber 15 and the air outlet channel 13. The air outlet channel 13 has two mist outlets 131, and the two mist outlets 131 are symmetrically arranged on both sides of the air outlet channel 13. The length of the mist outlet 131 is 60% to 95% of the height of the air outlet channel 13. In this embodiment, the length of the mist outlet 131 is 90% of the height of the air outlet channel 13.

[0044] Referring to Figure 3 and Figure 8 The mist outlet assembly 4 includes two mist outlet pipes 41 corresponding to the installation chamber 15 and arranged in the installation chamber 15, a mist outlet tee 42 for connecting the mist outlet pipe 41 and the atomizing device 3, and a connecting pipe 43 connecting the mist outlet pipe 41 and the mist outlet tee 42.

[0048] In combination Figures 1 to 9 The implementation principle of the spray fan according to an embodiment of the present application is as follows: the mist generated by the atomizing device 3 is divided into two mist outlets 131 of the mist outlet pipes 41 through the mist outlet tee 42. When the fan motor 221 drives the cross-flow fan 22 to rotate, the airflow enters the air inlet grille 17 of the mounting housing 11, and under the action of the cross-flow fan 22, the first guide plate 213 and the second guide plate 214, the airflow blows along the airflow channel to the air outlet channel 13, and forms a high-speed airflow in the air outlet channel 13. According to Bernoulli's principle, the air pressure at the air outlet channel 13 is lower, so that the mist in the mist outlet assembly 4 can be sucked out through the mist outlet 131, and under the action of the cross-flow fan 22, the mist is blown to a farther place, thereby improving the effect of diffusing the mist output by the spray fan to the surrounding environment.
