The fourth sawtooth bar and the second sawtooth bar form a V-shaped offset structure at the second air outlet 32, so that the air and other fluids can borrow fulcrums from each other in the process of passing through the second air outlet 32 ​​to be blown out of the wind knife. Under the same pressure and angle, the air flows and hits each other, which has the effect of mutually reinforcing the assistance, making the pressure stronger, and effectively improving the flow rate of the air compressed by the fan to be blown out of the wind knife through the second air outlet 32 ​​under the action of the rebound force. In the embodiment provided by the present invention, the third serrations and the fourth serrations are symmetrically arranged relative to the partition plate 20, so that the V-shaped staggered structure formed by the third serrations and the first serrations at the first air outlet 31 is symmetrical with the V-shaped staggered structure formed by the fourth serrations and the second serrations at the second air outlet 32, thereby making the structure of the double wind nozzle structure 30 formed by the partition plate 20 and the top ends of the first air guide portion 11 and the second air guide portion 12 more uniform, thereby effectively improving the flow rate of the air compressed by the fan blowing out of the wind knife through the first air outlet 31 and the second air outlet 32, while effectively simplifying the wind knife structure, reducing the volume of the wind knife, and improving the efficiency of blowing air out of the wind knife through the double wind nozzle structure 30 and onto the glass, thereby improving the drying efficiency of the glass cleaning machine using the double wind nozzle staggered wind knife 100 when drying glass.
