DETAILED DESCRIPTION

[0026] 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.

[0027] Please refer to Figure 1-9A quantitative powder taking device comprises a powder storage cylinder 2, one end of which is provided with a powder injection port 21, and the other end is provided with a powder outlet 22, the powder storage cylinder 2 comprises a circular outer cylinder 26 and a quadrilateral inner cylinder 23, any three sides of the circular outer cylinder 26 and the quadrilateral inner cylinder 23 are provided with corresponding slots 41, an elastic sealing mechanism is provided between the circular outer cylinder 26 and the quadrilateral inner cylinder 23, and the elastic sealing mechanism corresponds to the slots 41 one by one, and the plug plate 4 is inserted into any one of the slots 41 to isolate the internal quadrilateral inner cylinder 23 up and down, and after the plug plate 4 isolates the powder, the powder near the powder outlet 22 is discharged to achieve quantitative powder taking.

[0028] Please refer again Figure 3 and Fig. 9 Four slots 4 are provided on one side, three slots 4 are provided on the two adjacent left and right sides respectively, and the total number of slots is ten, and the ten slots 4 are arranged in an array in the height direction of the powder storage tube 2; the heights between each two adjacent slots on the three sides are consistent.

[0029] In the solution of the utility model, ten slots correspond to ten spoonfuls of quantitative powder, wherein the four slots on one side correspond to 1, 4, 7, and 10 spoonfuls of powder, the three slots on the left correspond to 2, 5, and 8 spoonfuls of powder, and the three slots on the right correspond to 3, 6, and 9 spoonfuls of powder, and labels of corresponding spoon numbers are affixed to the ten slots.

[0030] Before use, the powder is first injected into the powder storage tube 2 to fill the quadrilateral inner tube 23 with the powder, and then the powder can be taken out quantitatively; for example, if 6 spoonfuls of powder need to be taken out quantitatively, the insert plate 4 is inserted into the slot 41 corresponding to 6 spoonfuls. At this time, the internal powder is separated from the upper and lower parts by the insert plate 4, and the volume of the powder under the insert plate 4 is 6 spoonfuls. Finally, 6 spoonfuls of powder are discharged from the powder outlet 22.

[0031] Similarly, to take 10 spoons of powder, insert the plug plate into the top slot, and to take 1 spoon of milk powder, insert the plug plate into the bottom slot; according to needs, insert the plug plate 4 into the slot 41 corresponding to the number of spoons to quantitatively take powder. Inserting the plug plate 4 into different slots 41 will take out different volumes of powder to ensure the accuracy of powder taking; in the idle state, the plug plate is inserted into the top slot (10 spoons).

[0032] In the solution of the utility model, since the slot 41 passes through the quadrilateral inner cylinder 23 and the circular outer cylinder 26, the internal powder is easy to spill out from the slot 41 during use, causing waste. Therefore, the elastic sealing mechanism can avoid the waste of powder spilling and improve the overall sealing performance.

[0033] Specifically, the elastic sealing mechanism includes a sealing gate 261 and a spring 262 above the sealing gate 261, a gate platform 24 extending outward is provided on the quadrilateral inner cylinder 23, a spring fixing cylinder 25 is provided on the outer wall of the quadrilateral inner cylinder 23, one end of the spring 262 is fixed in the spring fixing cylinder 25, a countersunk hole is provided on the surface of the sealing gate 261, and the other end of the spring 262 is fixed in the countersunk hole of the sealing gate 261. Under normal circumstances, the bottom surface of the sealing gate is in contact with the surface of the gate platform 24; under normal circumstances (when the plug plate 4 is not inserted into the slot 41), the bottom surface of the sealing gate 261 is in contact with the surface of the gate platform 24, and the inner side of the sealing gate 261 is connected to the outer wall of the quadrilateral inner cylinder 23. At this time, the slot 41 is blocked by the sealing gate 261, and the internal powder cannot be spilled from the slot, thereby ensuring the overall sealing.

[0034] The sealing gate 261 has a sloped surface on the outside. During the quantitative powder taking process, the plug plate 4 needs to be inserted into the corresponding slot 41. At this time, the plug plate 4 passes through the sealing gate 261 when inserted into the quadrilateral inner cylinder 23 at the sloped surface. The sealing gate 261 moves upward through the spring 262. During the insertion, the bottom surface of the plug plate 4 contacts the surface of the gate platform 24, and the surface of the plug plate 4 contacts the bottom surface of the sealing gate 261. During the insertion and powder taking process, the internal powder cannot be spilled.

[0035] That is to say, in the idle state, the spring 262 pushes the sealing gate 261 downward through the downward elastic force, so that the bottom of the sealing gate 261 contacts the surface of the gate platform 24 to achieve sealing. When the plug plate 4 is inserted, the plug plate passes through the sealing gate 261, and the sealing gate 261 moves upward to squeeze the spring 262, and the upper and lower surfaces of the plug plate 4 contact the sealing gate 261 and the gate platform 24 respectively, and the sealing is also achieved; therefore, regardless of whether the powder is taken in a certain amount, the overall sealing can be guaranteed to prevent the internal powder from spilling.

[0036] In addition, a flexible rubber may be provided on the surface of the sealing gate 261, and the flexible rubber may be deformed when in contact, thereby further improving the sealing performance.

[0037] The inner wall of the quadrilateral inner cylinder 23 is provided with a limiting slideway 231, and the inserting plate 4 is provided with a smooth surface. The inserting plate 4 is smoothly inserted and pulled out of the quadrilateral inner cylinder 23 through the limiting slideway 231, thereby isolating the internal powder and ensuring the precision of quantitative powder extraction.

[0038] Furthermore, the powder injection port 21 is sealed by the powder injection port cover 1, and the powder outlet 22 is sealed by the powder outlet cover 3. The powder injection port cover 1 and the powder outlet cover 3 are both connected to the powder storage cylinder 2 through threads. When taking powder, the powder outlet cover 3 is screwed down by threads to leak out the powder outlet 22.

[0039] The powder filling port cover 1 is provided with a spare plug plate 5 with plug-in connection, wherein the powder filling port cover 1 is a double-layer structure, and the spare plug plate is arranged between the double-layer structure; the powder outlet cover 3 includes a waste powder collecting chamber 31, the bottom of the waste powder collecting chamber 31 is provided with a sealing plug 33, and the first filter screen 32 is provided at the upper port of the waste powder collecting chamber 31. After the powder is taken out, the residual powder passes through the first filter screen 32 and falls into the waste powder collecting chamber 31 to avoid spilling everywhere.

[0040] Based on the above embodiment, in order to ensure the smooth discharge of the internal powder, a vertical groove 6 is provided on the back of the powder storage tube 2, and a second filter screen 61 is provided in the vertical groove 6. An air hole is provided on the quadrilateral inner tube 23, and a third filter screen 27 is provided in the air hole. At this time, the interior of the quadrilateral inner tube 23 is connected with the outside through the third filter screen 27 and the second filter screen 61, and the atmospheric pressure inside and outside is consistent, which can ensure the smooth falling of the powder, avoid the bridging of the powder due to the lack of connection between the inside and the outside, and make the powder taking process more convenient.

[0041] Based on the above embodiment, the second filter screen 61 and the third filter screen 27 can allow the inside and outside air to communicate, but the powder cannot pass through, thereby preventing the powder from spilling out of the second filter screen 61 and the third filter screen 27; wherein the second filter screen 61 and the third filter screen 27 are not less than 200 meshes.

[0042] Based on the above embodiment, the slot 41 can also be arranged on one or more sides of the circular outer cylinder 26 and the quadrilateral inner cylinder 23, and the vertical slot 6, the second filter screen 61 and the third filter screen 27 can also be arranged on any one side or multiple sides.

[0043] 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.
