DETAILED DESCRIPTION

[0029] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0030] Please refer to Figure 1-11 A quantitative powder box sealing structure comprises a powder tube 1 and an outer tube 2 below the powder tube 1, the powder tube 1 and the outer tube 2 are detachably connected by a thread, a powder injection port 11 is provided on the top of the powder tube 1, a powder outlet 3 is provided on the bottom of the outer tube 2, an inner tube 21 is provided in the outer tube 2, the inner tube 21 is communicated with the powder tube 1, a plurality of corresponding insertion slots 4 are respectively provided around the outer tube 2 and the inner tube 21, one of the insertion slots 4 is provided with an insertion plate 5, the insertion plate 5 separates the powder in the inner tube 21 up and down, the powder under the insertion plate 5 falls out at the powder outlet 3, and an elastic sealing shell 24 corresponding to the insertion slot 4 is provided on the outer wall of the inner tube 21.

[0031] The cross section of the inner cylinder 21 is quadrilateral, and the slots 4 are arranged on any three sides; and in the height direction, the distance between each two adjacent slots 4 is consistent; that is, the inserting plate 5 can be inserted into the corresponding slot 4 to take out powders of different volumes, thereby ensuring the powder taking accuracy; in addition, due to the establishment of the elastic sealing shell 24, the overall sealing can be ensured to prevent the internal powder from spilling.

[0032] In this embodiment, different slots 4 correspond to different volumes of powder, and the gate plate 51 can be inserted into different slots 4 to take out different volumes of powder; when in use, the corresponding slot can be selected according to the amount of powder to be taken, so that the powder can be quantitatively taken out to ensure the powder taking accuracy.

[0033] In this embodiment, the inserting plate 5 includes an internal gate plate 51, and the gate plate 51 is inserted into the inner cylinder 21 in the inserting slot 4, so that the internal powder is separated up and down.

[0034] Specifically, the outer wall of the inner tube 21 is provided with a plurality of extension plates 22, the upper surface of the extension plate 22 is flush with the inner bottom surface of the insertion slot 4, and the lower surface of the extension plate 22 is in elastic contact with the elastic sealing shell 24; under normal conditions, the bottom surface of the elastic sealing shell 24 is in contact with the upper surface of the extension plate 22, and the internal powder is shielded by the elastic sealing shell 24; when in use, the elastic sealing shell 24 moves upward after the insertion plate 5 is inserted into the insertion slot 4, and the bottom surface of the elastic sealing shell 24 is in contact with the surface of the gate plate 51, and the insertion slot is shielded regardless of whether it is used or not, and the internal powder cannot penetrate, thereby ensuring the sealing of the powder box.

[0035] A countersunk hole 242 is provided above the elastic sealing shell 24, and a spring 25 is provided in the countersunk hole 242. One end of the spring 25 is provided in the countersunk hole 242, and the other end contacts the lower surface of the extension plate 22. When the gate plate 51 is inserted into the insertion slot 4, the elastic sealing shell 24 moves upward through the spring 25. After the elastic sealing shell 24 moves upward, a plug-in position is reserved for the gate plate 51. After the gate plate 51 is inserted, the insertion slot is blocked to prevent powder leakage.

[0036] In order to further ensure the vertical elastic movement of the elastic sealing shell 24, protrusions 28 are further provided on both sides of the outer wall of the inner cylinder 21. The four corners of the elastic sealing shell 24 are respectively provided with transversely extending ear plates 241, and the protrusion 28 is arranged between the two ear plates 241 on the same side; Figure 7 .

[0037] When the elastic sealing shell 24 moves upward, the lower ear plate 241 contacts the bottom surface of the protrusion. When the elastic sealing shell 24 elastically moves downward, the upper ear plate 241 contacts the surface of the protrusion. This limits the movement trajectory of the elastic sealing shell 24 and makes the overall operation more stable.

[0038] In order to prevent the elastic sealing shell 24 from falling off, ribs 23 are provided on the edges around the inner cylinder 21. The ribs 23 cover the ear plates 241 and the protrusions 28. After the ear plates 241 are covered, the elastic sealing shell 24 naturally cannot fall off. The ribs 23 are fixed to the inner cylinder 21 by screws 231.

[0039] A stepped hole 232 is provided on the surface of the rib 23, a spring 234 is provided in the stepped hole 232, and the screw 231 squeezes the spring 234 to fix the rib 23 on the inner tube 21. A notch 233 is also provided on one side of the rib 23, and both ends of the middle extension plate 22 are arranged at the notch 233.

[0040] Furthermore, in order to ensure smooth discharge of the powder under the gate plate 51, the inner cylinder 21 is provided with multiple groups of air holes 26 on the side where the insertion slot 4 is not provided, and multiple groups of air holes 27 are provided on the other three sides. A waste powder collecting chamber 244 is provided on the inner side of the elastic sealing shell 24, and the waste powder collecting chamber 244 covers the corresponding air hole 27. A through hole 243 is provided on the outer surface of the elastic sealing shell 24, and the air hole 26, the air hole 27, and the waste powder collecting chamber 244 are connected to the through hole 243.

[0041] In this embodiment, the inner diameters of the concentrated air hole 1 26 , the air hole 27 , the waste powder collecting chamber 244 and the through hole 243 are 1-3 mm.

[0042] The air hole 1 26, the air hole 27, and the waste powder collecting chamber 244 are connected to the through hole 243, and the main purpose is to exhaust air, avoid bridging of the internal powder, and ensure that the powder under the gate plate 51 is discharged smoothly;

[0043] During the exhaust process, a very small amount of powder will be discharged from the air vent 27 into the waste powder collection chamber 244 along with the air, so that the discharged waste powder can be collected; this phenomenon is very rare because the hole diameter is small, so the powder will hardly leak out from the air vent 1 26 or the air vent 2 27, or the amount that can leak out can be ignored, and the establishment of the waste powder collection chamber 244 can be understood as prevention and collection to avoid leakage.

[0044] This principle is similar to the air holes at the bottom of the milk powder spoon in the prior art, which are used for exhaust and higher storage and discharge of powder, and will not be elaborated here.

[0045] In this embodiment, different insertion slits correspond to air holes 1 at different heights to ensure smooth exhaust and powder extraction.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
