Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of 3D printing, in particular to a drip-proof flow guide nozzle and a 3D printing resin tank using the same. BACKGROUND

[0002] At present, 3D printing resin tanks are commonly used in light-curing 3D printing forming technology to hold resin solution. When the resin solution is poured for recycling, the resin solution often hangs on the wall and drips along the edge of the resin tank. Since the resin solution is not easy to clean and is a liquid with certain hazards, the dripping not only pollutes the environment but also causes continuous harm. Some single-layer nozzles have a certain anti-dripping effect for fast fluid, but when applied to viscous fluid such as resin solution, the solution is not easy to cut off in a short time due to its viscosity, so liquid is easily left at the end of the nozzle, resulting in dripping even after the resin tank is placed flat. Therefore, this single-layer nozzle cannot achieve anti-dripping and usually needs to be manually wiped. Therefore, a device is needed to prevent the resin solution from dripping. CONTENT OF THE INVENTION

[0003] The purpose of the present application is to provide a drip-proof flow guide nozzle and a 3D printing resin tank using the same. The drip-proof flow guide nozzle adopts a double-layer plate flow guide scheme, can guide the flow when pouring through the flow guide plate, and can collect the resin flowing back from the wall through the backflow plate, thereby preventing the resin solution from dripping.

[0004] The drip-proof flow guide nozzle provided by the present application is installed on the mouth of a container and used for guiding flow when pouring liquid. The drip-proof flow guide nozzle comprises a base, a flow guide plate, a backflow plate, a groove, and a flow guide port. The flow guide plate and the backflow plate are connected to the base in front of and behind each other. The flow guide plate is used for guiding flow when pouring liquid.

The groove is used for collecting the backflow liquid. The flow guide port is arranged at the bottom of the groove. The flow guide port penetrates through the flow guide plate. The flow guide port is used for guiding the collected liquid into the container.

[0005] Further, a fixing hole is arranged on the base. The fixing hole is used for fixing the drip-proof flow guide nozzle to the mouth of the container.

[0006] Further, notches are arranged on both sides of the flow guide plate. The notches are used for guiding liquid to the groove when the pouring flow of liquid is too large to prevent the liquid from overflowing outside the two sides of the flow guide plate.

[0007] Preferably, the number of flow guide ports is two. The flow guide ports are arranged on both sides of the bottom of the groove.

[0008] Preferably, the shape of the flow guide plate and the backflow plate is circular arc or angle.

[0009] Preferably, the surface of the flow guide plate is smooth; the surface of the backflow plate is smooth.

[0010] The purpose of the present application is also to provide a 3D printing resin tank, and specifically the 3D printing resin tank comprises the anti-dripping flow guide nozzle described above.

[0011] Further, the 3D printing resin tank comprises a frame, a release film and a film pressing frame; the frame is a hollow tank body; the release film is used for light curing printing light transmission and release film demolding; the film pressing frame tightens and fixes the release film to the bottom of the frame, so that the release film and the frame form a resin tank.
