Abstract
Description
Technical Field
[0001] This application relates to the field of 3D printing, and more specifically to a mist guide shell with fewer water droplets. Background Technology
[0002] Existing 3D printers for biomaterials (photopolymerization) typically fill the placement chamber with printing material, resulting in significant material waste after printing. To address this limitation, our company employs a small-droplet printing method. This involves adding only a small amount of printing material to the center of the placement chamber, rather than filling it completely, just enough to meet printing requirements. However, in practical applications, heating the placement chamber necessitates maintaining the humidity of the printing material at its center. Our previous design involved adding water and allowing it to evaporate, directing the moisture towards the printing material. However, this method is only suitable for low-frequency printing. For high-frequency printing, it necessitates frequent water additions, which is inconvenient.
[0003] Therefore, there is a need for a mist guide shell that requires no water addition, has a simple structure, and contains few water droplets inside the shell. Summary of the Invention

[0028] Schematic illustration of a low-water-droplet mist guide shell
[0029] refer to Figures 1 to 6 According to a preferred embodiment of the present invention, a low-water-droplet mist guide shell is provided, wherein the structure of the low-water-droplet mist guide shell is as follows: Figure 1 As shown, it includes a housing assembly disposed on the heating platform of an external 3D printer, wherein printing material is dripped onto... Figure 1 The heating platform of the external 3D printer shown is placed in the center of the housing 200. Specifically, the housing 200 has a first cavity 2001 with an opening. The bottoms of the two housing components are placed inside the housing 200 and spaced apart by a predetermined distance. It should also be noted that the housing components are configured to cooperate with an external atomizer, that is, the mist generated by the external atomizer can be guided through the housing components to the printing material located at the center of the housing. Furthermore, the housing components are configured to achieve arc-shaped spraying, thereby ensuring uniform humidity around the printing material and thus ensuring the printing effect.
[0030] Specifically, the housing assembly includes an upper housing 10 and a lower housing 20, which are fixedly connected. Specifically, the outer walls of the upper housing 10 and the lower housing 20 each have at least one first connecting portion 100, and the two first connecting portions 100 correspond one to one. The user can use external screws to thread the two first connecting portions 100 to define the position of the two first connecting portions 100.
[0031] Furthermore, both the upper housing 10 and the lower housing 20 are annular, and the top of the lower housing 20 has two opposing first arc-shaped grooves 201 and two opposing first guide grooves 202. The two first arc-shaped grooves 201 and the two first guide grooves 202 are staggered, and the two first arc-shaped grooves 201 and the two first guide grooves 202 together form a first annular cavity. The bottom of the upper housing 10 also has a second annular cavity 101. The first annular cavity and the second annular cavity 101 together form an airflow channel 300. It should also be noted that the outer wall of the lower housing 20 also has a second connecting portion 21. The second connecting portion 21 is configured to cooperate with an external atomizer, that is, the mist from the atomizer can be guided to the airflow channel 300 through the second connecting portion 21. The structures of the upper housing 10 and the lower housing 20 are as follows... Figure 2 and 3 As shown.
[0032] It should also be noted that when the upper housing 10 and the lower housing 20 are engaged, the upper housing 10 and the lower housing 20 together form two oppositely arranged ventilation gaps 400. Both ventilation gaps 400 are also connected to the airflow channel 300. Specifically, the mist placed in the airflow channel 300 can be guided through the two ventilation gaps 400 to the printing material located at the center of the housing.
[0033] It is worth mentioning that the bottom of the lower housing 20 has two opposing positioning notches 203. Specifically, those skilled in the art should understand that this utility model is placed on the heating platform of an external 3D printer. The external 3D printer also includes two positioning devices, which are configured to cooperate with the two positioning notches 203 respectively, thereby defining the position of the lower housing 20.
[0034] It should also be noted that during the misting process, the mist is guided to the printing material located in the center of the placement shell through the two ventilation openings 400. Therefore, during the humidification process, water droplets will be generated on the wall surface forming the ventilation openings 400. These water droplets will then fall onto the placement shell, resulting in a large accumulation of water droplets on the placement shell over time, which may affect the printing effect. Our company has made improvements to this part to address this issue.
[0035] Specifically, the bottom wall of each ventilation opening 400 is a slope, which guides the formed water droplets into the airflow channel 300, thereby making it less likely for the water droplets generated after misting to fall into the housing.
[0036] Furthermore, the bottom wall forming the second annular cavity 101 also has a plurality of evenly distributed first protrusions 1011, which are arranged in an arc shape and each is directly opposite one of the ventilation openings 400. The bottom wall forming the second annular cavity 101 also has a plurality of evenly distributed second protrusions 1012, which are arranged in an arc shape and each is directly opposite another ventilation opening 400. The structures of the first protrusions 1011 and the second protrusions 1012 are as follows: Figure 3 As shown, the plurality of first protrusions 1011 and the plurality of second protrusions 1012 are all inclined. In addition, the sides of the plurality of first protrusions 1011 and the plurality of second protrusions 1012 that are close to each other are all sloped surfaces. The bottom of the first protrusion 1011 abuts against the bottom wall of the corresponding ventilation opening 400, and the bottom of the second protrusion 1012 also abuts against the bottom wall of the corresponding ventilation opening 400. Thus, the plurality of first protrusions 1011 or the plurality of second protrusions 1012 divide the corresponding ventilation opening 400 into a plurality of spaced ventilation slots 4001.
[0037] It should also be noted that each of the first protrusions 1011 or the second protrusions 1012 has an arc-shaped notch at its bottom. The arc-shaped notch is designed so that the bottom of the first protrusion 1011 or the second protrusion 1012 effectively abuts against the bottom wall of the corresponding ventilation notch 400. Furthermore, the inclined surface of the first protrusion 1011 or the second protrusion 1012 allows water droplets formed on the inclined surface to be guided along the inclined surface of the first protrusion 1011 or the second protrusion 1012 to the inclined surface of the ventilation notch 400, thereby effectively reducing the amount of water droplets falling into the housing.
[0038] It should also be noted that the aforementioned placement shell 200 is configured to mate with the bottom of the lower shell, thereby defining the position of the placement shell. Furthermore, the upper and lower shells can be manufactured as a single piece, such as through blow molding.
[0039] In summary, the low-water-droplet mist guide shell based on the embodiments of this application has been clarified, which provides advantages such as no need to add water, simple structure, and fewer water droplets inside the shell.
[0040] It is worth mentioning that, in the embodiments of this application, the low-droplet mist guide shell has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the low-droplet mist guide shell provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
