The technical problem that evaporation nozzle is blocked.
In order to solve the above technical problems, the utility model provides a kind of evaporation source covering plate structure of evaporator, including evaporation
Nozzle and the first evaporation source cover board body and the second evaporation source cover board body positioned at evaporation nozzle right both sides, described first
The upper and lower surface of evaporation source cover board body and the second evaporation source cover board body is respectively covered with the netted braiding structure of pair of lamina.
Further, the first evaporation source cover board body and the second evaporation source cover board body longitudinal axis pair along where being deposited nozzle
Claim.
Further, the inclination angle of the first evaporation source cover board body and the second evaporation source cover board body horizontal by setting
Degree.
Further, the inclination angle between the first evaporation source cover board body and horizontal plane is 90 ° to 180 °, and second steams
The inclination angle risen between cover board body and horizontal plane is 0 ° to 90 °.
Further, the netted braiding structure of bilayer is formed by the first braiding layer and the braiding of the second braiding layer, the net
Shape braiding structure is close to the upper surface or footwear surface of the first evaporation source cover board body or the second evaporation source cover board body.
Further, the mesh aperture of first braiding layer is less than the mesh aperture of the second braiding layer.
Further, the woven stripe width of first braiding layer is more than the width of the woven stripe of the second braiding layer.
Further, the mesh form of first braiding layer and the second braiding layer is made as needed.
The beneficial effects of the utility model are：In the evaporation source covering plate structure of the evaporator of the utility model, it is being deposited
The upper and lower surface of the evaporation source cover board body of nozzle right both sides covers double-deck netted braiding structure, makes what is sprayed from evaporation nozzle
Evaporation material is deposited in the mesh of double-deck netted braiding structure, effectively reduces the organic material accumulated on evaporation source cover board, pole
It is big to improve the evaporation source continuous use time, so as to improve production capacity；Avoid evaporation material to block evaporation nozzle at the same time, it is good to improve product
Rate.
Brief description of the drawings
Fig. 1 is the evaporation source structure diagram of evaporator in the utility model；
