Detailed Description
The utility model will be further described with reference to the drawings and embodiments.
Referring to fig. 1 to 3 in combination, a double-layer wind scooper comprises a wind scooper outer shell 2 and a wind scooper inner shell 1 fixed on the inner side of the wind scooper outer shell 2, wherein the wind scooper outer shell 2 and the wind scooper outer shell 2 are fixedly connected through screws, so that the wind scooper is convenient to install and detach, and a concentric double-layer structure is formed in a space between the wind scooper inner shell 1 and the wind scooper outer shell 2;
the air guide cover inner shell 1 comprises an inner cavity 1A, an air tap 1B arranged at one end of the inner cavity 1A and an air pipe interface 1C arranged between the inner cavity 1A and the air tap 1B, wherein an air passage is arranged in the air pipe interface 1C and is communicated with the inner cavity 1A and the air pipe interface 1C;
an outer cavity 2A is arranged between the air guide cover outer shell 2 and the air guide cover inner shell 1, an air pipe interface 1C is positioned in the outer cavity 2A, and an air outlet 2B is arranged between the air guide cover outer shell 2 and the air tap 1B.
It is emphasized that: this bilayer wind scooper installs on the laser module, and the laser module includes the shell and installs the laser tube core subassembly 4 inboard at the shell, and the sealing washer 5 is used to the hookup location of wind scooper inner shell 1 and laser tube core subassembly 4 is sealed, and radiator fan 6 that is used for carrying out radiating to laser tube core subassembly 4 is installed to laser tube core subassembly 4 one end, and outer cavity 2A is in radiator fan 6's wind channel end, and the external trachea 3 of trachea interface 1C links to each other with the air supply, the tip of trachea interface 1C is the round platform shape, is convenient for be connected with trachea 3.
The outer wall of the end part of the air tap 1B is provided with a chamfer 1B1, so that air flow is blown away to the air tap 1B along the chamfer 1B.
The side wall of the air guide cover shell 2 is provided with a mounting plate 2C, and the mounting plate 2C is provided with mounting holes, so that the air guide cover shell 2 is conveniently connected with a laser module.
Working principle: the radiator fan 6, the laser tube core assembly 4 and the air guide cover are vertically distributed, laser is emitted from the air tap 1B, the air guide cover shell 2 is positioned at the tail end of an air channel of the radiator fan 6, the outer diameter of the air guide cover shell 2 is large enough, the outer cavity 2A can bear a certain air quantity, and the air quantity is converged to the air outlet 2B through the outer cavity 2A which is gradually reduced. Because the air tap 1B and the air outlet 2B are coaxially distributed, certain air flows exist all the time around the air tap 1B, and when laser engraving is performed, the air sources are required to be closed, and the air flows guided by the air radiator fan 6 can play a role in blowing dust and preventing the plug.
