The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
As shown in fig. 1-2, the print head of the 3D printer comprises a spray head 5, a flow guide groove 6, a cooling fan 7 and an extruder 8, the print head moves on a first X-axis cross bar 9 and a second X-axis cross bar 10 of the 3D printer, the cooling fan 7 is arranged above the flow guide groove 6, the flow guide groove 6 is connected with an obliquely opposite vortex airflow generator, the obliquely opposite vortex airflow generator comprises a generator body, the obliquely opposite vortex airflow generator consists of a left air outlet 1 and a right air outlet 2 which are obliquely opposite and are centered on the spray head 5, a left air flow guide claw 3 is arranged on the left air outlet 1, a right air flow guide claw 4 is arranged on the right air outlet 2, and air flows generated by the cooling fan 7, through the flow guide groove 6, enter the obliquely opposite vortex airflow generator and flow out of the left air outlet 1 and the right air outlet 2 of the obliquely opposite vortex airflow generator respectively.
Wherein, left side air outlet 1 and right side air outlet 2 are mirror image design, and left side air flow guiding claw 3 and right side air flow guiding claw 4 are mirror image design.
Because the 3D printer is in the printing process, the moving direction of the nozzle 5 is mostly anticlockwise (overlook angle), as shown in fig. 4, the left air flow guiding claw 3 and the right air flow guiding claw 4 are respectively carried on the left auxiliary air outlet 12 and the right auxiliary air outlet 14, and the set positions are left, front and right, so that anticlockwise annular heat dissipation air flow is formed, and the air flow is beneficial to dissipating heat along the moving direction of the nozzle 5.
As shown in fig. 4, the left main air outlet 11 and the right main air outlet 13 are provided as inclined air outlets, the inclined air outlets are inclined in a horizontal direction and a vertical direction, the inclined direction of the left main air outlet 11 in the horizontal direction is from top left to bottom right, and the inclined direction of the right main air outlet 13 in the horizontal direction is from bottom right to left.
As shown in fig. 3, the design of the inclined air outlets of the left main air outlet 11 and the right main air outlet 13 makes bidirectional air flows staggered, so as to avoid the reduction of heat dissipation efficiency caused by the opposite impact of the air flows.
As shown in fig. 4, the inclination direction of the left side auxiliary air outlet 12 of the left side air outlet 1 in the horizontal direction is from left to right and the inclination direction of the right side auxiliary air outlet 14 of the right side air outlet 2 in the horizontal direction is from right to left and from top to bottom;
as shown in fig. 3, the left air outlet 1 is inclined from top to bottom, and as can be seen in fig. 3, the included angle between the left air outlet 1 and the air outlet direction of the left main air outlet 11 is an acute angle, and the included angle between the right auxiliary air outlet 14 of the right air outlet 2 and the air outlet direction of the right main air outlet 13 is an acute angle.
As shown in fig. 3, the air flow blown out from the left auxiliary air outlet 12 is faster than the air flow of the left main air outlet 11, so that the air flow of the left auxiliary air outlet 12 is firstly contacted with the left air flow guiding claw 3, and then the oblique air flow blown out from the left main air outlet 11 is integrated, so that the excessive loss of the oblique air flow of the left main air outlet 11 is avoided. The airflow blown out from the right side auxiliary air outlet 14 of the right side air outlet 2 is faster than the airflow blown out from the right side main air outlet 13, so that the airflow of the right side auxiliary air outlet 14 is firstly contacted with the right side airflow guiding claw 4, and then the oblique airflows blown out from the right side main air outlet 13 are integrated, so that the excessive loss of the oblique airflows of the right side main air outlet 13 is avoided.
As shown in fig. 4, since the left air guide claw 3 and the right air guide claw 4 have a certain bending angle in the horizontal direction, the air flow blown out from the left auxiliary air outlet 12 has a certain rotation angle in the air flow direction under the guidance of the left air guide claw 3, and the air flow blown out from the right auxiliary air outlet 14 has a certain rotation angle in the air flow direction under the guidance of the right air guide claw 4.
As shown in fig. 3, the air flows from the left main air outlet 11 and the left sub air outlet 12 are guided by the left air flow guide claw 3 and the right air flow guide claw 4, and after being merged with the air flows from the right main air outlet 13 and the right sub air outlet 14, a counterclockwise (in a top view) air flow vortex is formed around the nozzle 5.
As shown in fig. 5, taking the left air outlet 1 as an example, the left air outlet 1 is formed by combining a left main air outlet 11 and a left auxiliary air outlet 12, and is divided into the left main air outlet 11 and the left auxiliary air outlet 12 according to the size of the air outlet, and the air inlets of the left main air outlet 11 and the left auxiliary air outlet 12 are equal in size, but since the air outlet of the left main air outlet 11 is larger than the air outlet of the left auxiliary air outlet 12, the air flow blown out by the left main air outlet 11 is relatively low-speed air flow, the air flow blown out by the left auxiliary air outlet 12 is high-speed air flow, and the left air flow guide claw 3 is mounted on the left auxiliary air outlet 12.
As shown in fig. 8, the end of the left air flow guiding claw 3 is set to twist downwards by a certain angle in the vertical direction, while as can be seen in fig. 6, the opening direction of the left main air outlet 11 is set to tilt downwards by a certain angle in the vertical direction, and as can be seen in fig. 7, the opening direction of the left auxiliary air outlet 12 is set to tilt downwards by a certain angle in the vertical direction, so that the swirl air flow formed by converging the air flows from the air outlets on both sides is under the nozzle 5, and the swirl air flow cools the printing material from the nozzle 5, but does not cool the nozzle 5 itself.
As shown in fig. 9, the air flow forms a counter-clockwise swirl heat dissipation air flow in the horizontal direction under the action of the diagonally opposite swirl air flow generator, and simultaneously forms a swirl air hole in the center.
As shown in fig. 10, the nozzle 5 is located directly above the swirl hole, so the nozzle 5 itself is not affected by the swirl flow. Because the printing head is in the printing process, the moving direction of the spray head 5 is mostly anticlockwise (overlook angle), and the anticlockwise swirl airflow flowing direction is the same as the moving direction of the spray head 5, so that the airflow can radiate along the moving direction of the spray head 5.
As shown in fig. 10, by the action of the diagonally opposite swirl flow generators, the swirling heat dissipation air flow is formed to be inclined downward in the vertical direction, and the inclined downward air flow is beneficial to cool the printing material coming out of the ejection head 5.
Under the holding of the radiating effect of the omnidirectional vortex cooling, the 3D printer can successfully print the arm-spread structure with the included angle of 0-85 degrees with the vertical direction under the unsupported condition, so that the structural reliability of the 3D printing model is enhanced, meanwhile, the phenomena of wiredrawing, curling, thermal deformation, bridging sagging and the like are reduced, and the success rate of 3D printing is improved.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
