[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer.

[0003] Photocuring is the most mainstream method in 3D printing. This method will leave residues on the surface after printing. In order to ensure the smoothness of the surface after printing, polishing is usually required, which will result in more residues on the surface of the printed parts. Therefore, the printed parts need to be cleaned after printing. There are special cleaning equipment in the industry, and home 3D printers usually use ultrasonic cleaning machines to clean the printed parts. However, ultrasonic cleaning machines are relatively expensive and have a low cost-effectiveness for most people. Therefore, most users use water flushing to clean the printed parts. Although this method is economical and inexpensive, the cleaning efficiency and cleaning effect are not high. Therefore, a photocuring 3D printed parts cleaning device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, the utility model provides a light-cured 3D printed part cleaning device to solve the problems of high cost and low water flushing efficiency of existing cleaning machines.

[0031] See also Figure 1 , Figure 2 and Figure 5 , a light-cured 3D printed part cleaning device, comprising:

[0032] A cleaning bucket 1 comprises a barrel body 11, a plug hole 12, a water outlet pipe 13, a water inlet pipe 14, a water inlet hole 15 and a first groove 16. The bottom wall of the barrel body 11 is provided with a plug hole 12, the inner wall of the barrel body 11 is provided with a water inlet pipe 14, the outer surface of the water inlet pipe 14 is provided with a water inlet hole 15, the upper surface of the barrel body 11 is provided with a first groove 16, the first groove 16 is communicated with the water inlet pipe 14, the outer surface of the barrel body 11 is provided with a water outlet pipe 13, and the water outlet pipe 13 is communicated with the barrel body 11;

[0033] A mounting post 5, which is disposed inside the plug hole 12;

[0034] Based on the above, the water flowing into the water inlet pipe 14 can enter the interior of the barrel body 11 through the water inlet hole 15 and be discharged from the water outlet pipe 13, and the setting of the first groove 16 provides a movable space for the pressure spring 7 and the positioning column 8. The mounting column 5 and the plug-in hole 12 cooperate with each other, so that the printed part can be clamped in the cleaning barrel 1 by the mounting column 5, and the effect of fixing different printed parts can be achieved by adjusting the number and position of the mounting column 5.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the regulating inner cylinder 2 is arranged inside the water inlet pipe 14 and includes a communicating hole 22 and a positioning groove 24. The regulating inner cylinder 2 includes an inner cylinder body 21, and the inner cylinder body 21 is arranged inside the water inlet pipe 14. The outer surface of the inner cylinder body 21 is provided with a communicating hole 22, and the communicating hole 22 is connected with the water inlet hole 15. The top end of the inner cylinder body 21 is provided with a top pipe 23, and the outer surface of the top pipe 23 is provided with a positioning groove 24.

[0036] A middle piece 3, which is arranged at the top end of the adjusting inner cylinder 2 and extends to the inside of the adjusting inner cylinder 2;

[0037] Based on the above, the setting of the adjusting inner cylinder 2 plays a role in adjusting the direction of water flow entering the cleaning bucket 1. The middle piece 3, the external water pump 6 and the water outlet pipe 13 are connected by a hose, so that the water flow can circulate between the above three and the cleaning bucket 1. At this time, the water flow entering the water inlet pipe 3 through the adjusting inner cylinder 2 flows into the interior of the cleaning bucket 1 from the connecting hole 22 and the water inlet hole 15. By rotating the adjusting inner cylinder 2, the connecting hole 22 is connected to the water inlet holes 15 at different positions, thereby achieving the effect of changing the direction of the water flow.

[0038] like Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, a top cover 4 is arranged at the top of the cleaning bucket 1, and the top cover 4 includes a cover plate 41, and a lower surface of the cover plate 41 is provided with a through hole 42 and a second groove 43 that are interconnected;

[0039] The pressure spring 7 and the positioning column 8 are both arranged between the cleaning bucket 1 and the top cover 4. The positioning column 8 extends to the inside of the positioning groove 24. The pressure spring 7 is arranged between the second groove 43 and the first groove 16. The positioning column 8 is arranged at one end of the pressure spring 7 close to the positioning groove 24. The surface of the positioning column 8 extending to the positioning groove 24 is an arc surface, and the positioning groove 24 is an arc groove.

[0040] Based on the above, after the top cover 4 and the cleaning bucket 1 are connected to each other, they play a limiting role on the pressure spring 7 and the positioning column 8, so that the positioning column 8 can only move along the direction of the first groove 16 and the second groove 43. The positioning column 8 fits tightly with the positioning groove 24 under the action of the elastic force of the pressure spring 7.

[0041] In actual use of this embodiment, the external water pump 6, the middle piece and the water outlet pipe 13 are connected by a hose, so that water can circulate between the above three and the cleaning bucket 1;

[0042] The inner cylinder 2 is rotated to adjust the position of the communicating hole 22. During the rotation, the positioning groove 24 squeezes the positioning column 8, so that the positioning column 8 moves toward the direction close to the pressure spring 7 and squeezes the pressure spring 7 to generate a reverse elastic force. When the next positioning groove 24 rotates to the position of the positioning column 8, the positioning column 8 is clamped into the interior of the positioning groove 24 under the action of the elastic force, so that the inner cylinder 2 is adjusted and fixed after the angle is changed.

[0043] By changing the position of the connecting hole 22, the direction of the water flowing into the washing barrel 1 is changed. Direction 1 is moving along the inner wall of the barrel body 1, that is, the path of the water flow is circular. Direction 2 is vertical inflow, that is, vertically flushing the printed piece in the washing barrel 1. At this time, the impact force is the largest. Direction 3 is between the above two directions and has the characteristics of the above two directions, but the effect is not as good as the above two directions.

[0044] When the water flows along the direction of the inside of the barrel body 1, a vortex is generated inside the washing barrel 1. Under the action of the vortex, the printed part stuck in the washing barrel 1 by the mounting column 5 is flushed and cleaned. This method can fully clean all parts of the printed part.

[0045] By inserting the mounting column 5 into different plug holes 12, the effect of restricting different printed parts can be achieved, so that the device can be suitable for different printed parts. Compared with an ultrasonic cleaning machine, the device has a simple structure and a low cost. Compared with simply placing the printed part under water for washing, the device is more efficient and has a better cleaning effect, and is more suitable for personal use.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
