Example one
The feeding device is used for a three-dimensional printer and comprises a material storage tank 100, an air inlet pipe 101 and a material outlet pipe 102; the material storage tank 100 is used for storing materials, and the material storage tank 100 is arranged above a material tray 103 of the three-dimensional printer; the air inlet end 106 of the air inlet pipe 101 is located outside the storage tank 100 and is a first preset distance away from the bottom surface of a tray 103 of the three-dimensional printer, and the air outlet end 107 of the air inlet pipe 101 is located inside the storage tank 100 and is located above the liquid level of the material; the feed end 108 of the discharge pipe 102 is located in the liquid level of the material in the storage tank 100, and the discharge end 109 of the discharge pipe 102 is used for the charging tray 103 to add the material.
In consideration of the application of providing a material to a three-dimensional printer, the material is exemplified as a photosensitive resin in this embodiment and the following embodiments.

Referring to fig. 2, a part of the air inlet pipe 101 is disposed outside the storage tank 100, an air inlet end 106 of the air inlet pipe 101 is located outside the storage tank 100 and is a first preset distance away from the bottom surface of a tray 103 of the three-dimensional printer, and an air outlet end 107 of the air inlet pipe 101 is located inside the storage tank 100 and is located above the liquid level of the photosensitive resin.
In the actual use process, the discharging pipe 102 and the air inlet pipe 101 are aligned with the tray 103, the discharging pipe 102 is used for conveying photosensitive resin, and the air inlet pipe 101 is used for communicating the inside of the storage tank 100 with the atmosphere, specifically, the position of the air inlet end 106 of the air inlet pipe 101 inside the storage tank 100 is higher than the liquid level of the photosensitive resin in the storage tank 100, in other words, the air outlet end 107 of the air inlet pipe 101 cannot be immersed in the photosensitive resin liquid, in addition, the distance between the air inlet end 106 of the air inlet pipe 101 and the bottom surface of the tray 103 can be set according to the required liquid level in the tray 103, in other words, the preset liquid level H in fig. 1 determines the storage amount of the photosensitive resin in the tray 103.
More specifically, when the liquid level of the photosensitive resin in the material tray 103 is less than the preset liquid level H (i.e., the first predetermined distance), the interior of the material storage tank 100 is communicated with the atmosphere, and the photosensitive resin in the material storage tank 100 flows into the material tray 103 from the discharge pipe 102 under the action of the self gravity. When the liquid level of the photosensitive resin in the material tray 103 reaches the preset liquid level H, the air inlet end 106 of the air inlet pipe 101 is blocked by the photosensitive resin, and the inside of the material storage tank 100 is not communicated with the atmosphere, so that the photosensitive resin in the material storage tank 100 is in a balanced state, namely, the material storage tray 103 is not fed. And as the photosensitive resin in the material tray 103 is supplied to the three-dimensional printer for use, when the photosensitive resin is gradually supplied to the three-dimensional printer, the photosensitive resin in the material tray 103 is gradually reduced, when the liquid level height of the photosensitive resin in the material tray 103 is smaller than the preset liquid level height H, the material storage tank 100 is communicated with the atmosphere again through the air inlet pipe 101, the photosensitive resin in the material storage tank 100 continuously flows into the material tray 103 from the discharge pipe 102 under the action of self gravity, and therefore automatic circulating feeding of the three-dimensional printer is achieved.
