DETAILED DESCRIPTION

[0031] The following will be combined with the drawingsFigures 1-2 This application is described in further detail.

[0032] The present application discloses a plug-in high-discharge fan, referring to Figure 1 and Figure 2 As shown, the plug-in high-exhaust fan includes a chassis 1, a multi-parameter exhaust gas detection probe 2, a control mechanism 3, a driving mechanism 4, an installation mechanism 5 and a protection mechanism 6. The chassis 1 is horizontally arranged, and the length direction of the chassis 1 is perpendicular to the ground.

[0033] Reference Figure 1 and Figure 2 As shown, an exhaust port 11 and an air outlet 12 are provided on the chassis 1, and the air outlet 12 is located above the exhaust port 11. A multi-parameter exhaust gas detection probe 2 is provided in the chassis 1, and the multi-parameter exhaust gas detection probe 2 is provided at the air outlet 12. A fresh air duct 13 is provided on the side of the chassis 1, and the fresh air duct 13 is connected to the exhaust port 11. A bypass valve 14 is provided in the fresh air duct 13.

[0034] Reference Figure 1 and Figure 2 As shown, during the exhaust gas emission process, when the multi-parameter exhaust gas detection probe 2 detects that the exhaust gas concentration meets the emission standard, the bypass valve 14 is controlled to close the fresh air duct 13, and the fresh air duct 13 does not transmit fresh air. When the multi-parameter exhaust gas detection probe 2 detects that the exhaust gas concentration is higher than the emission standard, the bypass valve 14 is controlled to open the fresh air duct 13, and the fresh air duct 13 transmits fresh air, which can automatically adjust the exhaust gas concentration and save resources.

[0035] Reference Figure 1 and Figure 2 As shown, a high-voltage optical network 131 is detachably provided at the entrance of the fresh air duct 13, and a high-voltage optical network 15 is detachably provided at the exhaust port 11, thereby reducing the possible impact of mosquitoes on the indoor environment and improving the safety of the fan operation. The low-temperature plasma generated by the high-frequency voltage of the high-voltage optical network 131 and the high-voltage optical network 15 causes the VOCS to undergo ionization, dissociation and oxidation reactions, generating harmless or low-toxic substances, thereby achieving the purpose of killing bacteria.

[0036] Reference Figure 1 and Figure 2As shown, the regulating mechanism 3 includes a blade 31 and an electric regulating valve 32. The electric regulating valve 32 is arranged in the chassis 1. The blade 31 is rotatably arranged in the chassis 1. The blade 31 is arranged above the exhaust port 11. The blade 31 is arranged obliquely above the bypass valve 14. In the process of discharging exhaust gas, the exhaust gas discharge rate can be controlled by adjusting the flip angle of the blade 31. When the blade surface of the blade 31 is controlled by the bypass valve 14 to be parallel to the ground, the ventilation gap left is small, which reduces the exhaust gas discharge rate. When the blade surface of the blade 31 is controlled by the bypass valve 14 to be vertical to the ground, the ventilation gap left is large, which increases the exhaust gas discharge rate, thereby facilitating the adjustment of the exhaust gas discharge rate.

[0037] Reference Figure 1 and Figure 2 As shown, the driving mechanism 4 includes a motor 41 and an impeller 42. The motor 41 is arranged in the chassis 1. The impeller 42 is fixed to the output shaft of the motor 41. The impeller 42 is located above the blade 1 31. The motor 41 is located above the impeller 42. The impeller 42 is a mixed flow impeller 42.

The induction effect can provide an airflow that is three times its own, thereby reducing the concentration of pollutants, achieving compliant emissions, reducing energy consumption, and improving the exhaust emission effect.

[0039] Reference Figure 1 and Figure 2 As shown, the protective mechanism 6 includes a damper blade 61, which is rotatably arranged in the chassis 1. During the exhaust gas discharge process, the exhaust gas gives the damper blade 61 a force to flip upward, and the damper blade 61 is away from the air outlet 12 of the chassis 1, so that the exhaust gas can be discharged. The damper blade 61 can prevent rainwater from entering the chassis 1 on rainy days and causing damage to the fan, thereby further improving the overall working stability of the fan.

[0040] Reference Figure 1 and Figure 2 As shown, the mounting mechanism 5 includes a placement tube 51 and a heat dissipation tube 52. The placement tube 51 is arranged on the chassis 1. The placement tube 51 is connected to the inside of the chassis 1.
