Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing pen technology, and more specifically, it relates to a flow divider for a 3D printing pen and a 3D printing pen. Background Technology
[0002] With the development of 3D printing technology, the combination of 3D printing and food is the future trend of 3D printing technology. In food printing with 3D printing pens, the current products on the market use liquid material output, resulting in poor 3D stacking. Therefore, in order to achieve good stacking during the printing process, semi-solid printing material is usually extruded directly through the nozzle. However, this method often suffers from uneven heating and clumping of the printing material, which can easily cause the printing material to accumulate in the nozzle of the 3D printing pen and become unusable. To address this, we provide a new 3D printing pen flow divider and 3D printing pen. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a 3D printing pen diverter and a 3D printing pen to solve the above-mentioned technical problems.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flow divider for a 3D printing pen, comprising: a shuttle body; the shuttle body having a conical structure; a flow divider cavity provided at the upper end of the shuttle body; the flow divider cavity being provided with a plurality of inner channels for the passage of printing material and a plurality of outer channels for the passage of printing material; the plurality of inner channels and the plurality of outer channels being arranged in a concentric ring; the plurality of inner channels and the plurality of outer channels being arranged perpendicular to each other; the feed inlets of the plurality of inner channels and the plurality of outer channels being provided with arc-shaped material guiding structures; and the outer wall of the shuttle body being symmetrically provided with locking slots for engaging with the inner wall of the storage cylinder of the 3D printing pen.
[0005] Optionally, the flow divider cavity is a conical flow divider cavity.
[0006] Optionally, the inner flow channel and the outer flow band have the same diameter, and their diameters are both 1mm-3mm.
[0007] Optionally, the outer wall of the shuttle body is provided with several slots at equal intervals.
[0008] Optionally, the depth of the card slot is 1mm-3mm.
[0009] This application also discloses a 3D printing pen that includes the structure of the 3D printing pen diverter described above.
[0010] In this invention, the inner and outer flow channels on the shuttle body can simultaneously divert and discharge the printing material in the storage cylinder of the 3D printing pen, so that during the semi-solid discharge process, the material does not accumulate in the nozzle of the 3D printing pen, thus preventing the 3D printing pen from becoming unusable.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0016] In this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] This utility model provides a flow divider for a 3D printing pen, such as... Figure 1-2 As shown, it includes: a shuttle body 1; the shuttle body 1 has a conical structure; the upper end of the shuttle body 1 is provided with a flow-dividing cavity 2; the flow-dividing cavity 2 can be provided with a plurality of inner flow channels 3 for the passage of printing material and a plurality of outer flow channels 4 for the passage of printing material; the plurality of inner flow channels 3 and the plurality of outer flow channels 4 are arranged in a concentric ring shape; the plurality of inner flow channels 3 and the plurality of outer flow channels 4 are arranged perpendicular to each other; the feed inlets of the plurality of inner flow channels 3 and the outer flow channels 4 are all provided with arc-shaped material guiding structures 7; the outer wall of the shuttle body 1 is symmetrically provided with locking slots 5 for engaging with the inner wall of the storage tube of the 3D printing pen; the inner flow channels 3 and the outer flow channels have the same diameter, and their diameters are both 1mm-3mm.
[0019] In this embodiment, the flow divider is installed inside the material storage cylinder of the 3D printing pen and located near the nozzle of the 3D printing pen (i.e., below the piston and the printing material). In this embodiment, the diameters of the inner flow channel 3 and the outer flow channel on the shuttle body 1 are much smaller than the diameter of the nozzle of the 3D printing pen. During operation, the semi-solid printing material is divided and discharged through the shuttle body 1 under the pressure of the piston, and then conveyed out from the nozzle of the 3D printing pen for material stacking. This effectively avoids the situation where semi-solid printing material accumulates in the nozzle of the 3D printing pen, causing the 3D printing pen to malfunction.
[0020] Furthermore, the flow divider 2 is a conical flow divider 2.
[0021] Optionally, the outer wall of the shuttle body 1 is provided with several slots 6 at equal intervals; by providing the slots 6, the shuttle body 1 can be connected and installed in the storage cylinder of the 3D printing pen, so as to avoid displacement and loosening.
[0022] Optionally, the depth of the slot 6 is 1mm-3mm.
[0023] This application also discloses a 3D printing pen that includes the structure of the 3D printing pen diverter described above.
[0024] This utility model discloses a flow divider shuttle for a 3D printing pen. The inner flow channel 3 and the outer flow channel 4 on the shuttle body 1 can simultaneously divide and discharge the printing material in the storage cylinder of the 3D printing pen. This prevents the material from clogging the nozzle of the 3D printing pen during the semi-solid discharge process, thus avoiding the situation where the 3D printing pen cannot be used normally.
[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
