For those skilled in the art, the specific meanings of the above - mentioned terms in the present utility model can be understood according to specific situations.

[0031] The present utility model provides a powder equal - quantity distribution device for an automatic coffee machine, which can accurately control the discharge amount with a simple structure as Figure 1 shown.

[0032] A powder equal - amount distribution device for an automatic coffee machine, comprising an equal - amount mechanism and a motor 7; the equal - amount mechanism is used to store equal amounts of powder, including a fixed component 1 and a moving component 2, and equal - amount cells 3 on the moving component 2; the fixed component 1 serves as a housing, the moving component 2 is arranged inside the fixed component 1 and moves driven by the motor 7, a powder inlet 4 is provided above the fixed component, and a powder outlet 5 is provided below. The moving component 2 receives powder from the powder inlet 4 and then discharges the powder in the equal - amount cells from the powder outlet 5; the motor 7 is arranged on the fixed component 1 and is connected to the moving component 2.

[0033] During use, the moving component 2 is installed inside the fixed component 1 and connected to the motor 7. The moving component 2 and the inner wall of the fixed component 1 form equal - amount cells 3. When the motor 7 drives the moving component 2 to rotate, when the empty equal - amount cell 3 rotates to the powder inlet 4, it can receive and store the powder transferred from above, and then continues to rotate to the powder outlet 5 driven by the motor 7. The powder drops from the powder outlet 5 under the action of gravity to complete the batching.

[0034] Embodiment 1

[0035] In this embodiment, as Figure 1-4 shown, the moving component 2 is a windmill - type distributor. The windmill - type distributor includes a plurality of identical wing plates 8 and a rotating shaft. The rotating shaft is integrally formed with the plurality of identical wing plates 8. The number of wing plates 8 can be determined according to the amount of powder to be added.

[0036] Two adjacent wing plates 8 of the moving component 2 form an equal - amount cell 3. When the number of wing plates 8 is large, the volume of the equal - amount cell 3 formed by the two wing plates 8 and the inner wall of the fixed component 1 is smaller. When the number of wing plates 8 is small, the volume of the equal - amount cell 3 formed by the two wing plates 8 and the inner wall of the fixed component 1 is larger.

[0037] During use, the moving component 2 of the windmill - type distributor rotates driven by the motor 7. The equal - amount cell 3 formed by the wing plates 8 of the windmill - type distributor, when rotating to the powder inlet 4, the powder falls from the powder inlet 4 and is stored in the equal - amount cell. The motor 7 continues to drive the moving component 2 to rotate, driving the equal - amount cell 3 storing the powder to the powder outlet 5, and the powder drops from the powder outlet 5 to complete the batching.

[0038] Embodiment 2

[0039] In this embodiment, as Figures 5-6As shown, the moving component 2 is a turntable-type dispenser with a through hole penetrating up and down to form equal compartments 3; the fixed component 1 is a cylindrical shell and is coaxial with the moving component 2. One side of the upper wall of the fixed component 1 is provided with a powder inlet 4, and one side of the lower wall far from the powder inlet 4 is provided with a powder outlet 5. The distances from the powder inlet 4, the powder outlet 5, and the axis of the equal compartment 3 to the axis of the fixed component 1 with a cylindrical shell are all the same. The motor 7 is arranged at the axis of the fixed component 1 and is connected to the moving component 2, and can control the moving component 2 to rotate along the axis on the fixed component 1.

[0040] During use, the motor 7 drives the moving component 2 to rotate, so that the equal compartment 3 rotates to the lower part of the powder inlet 4, and the powder falls from the powder inlet 4 into the equal compartment 3. The motor 7 continues to drive the moving component 2 to rotate in the direction shown. Figure 6 so that the equal compartment 3 rotates to the upper part of the powder outlet 5, and the powder falls from the equal compartment, reciprocating to complete batching.

[0041] Compared with Embodiment 1, in this embodiment, the moving component 2 and the fixed component 1 are disc-shaped, which can effectively save space in height and is more suitable for use in cases where the space in the axial direction is small.

[0042] Embodiment 3

[0043] In this embodiment, as shown Figure 6 the moving component 2 is a cuboid dispenser with a through hole penetrating up and down to form equal compartments 3. The fixed component 1 is a cuboid shell. One side of the upper wall of the fixed component 1 is provided with a powder inlet 4, and one side of the lower wall far from the powder inlet 4 is provided with a powder outlet 5. The motor 7 is arranged on the fixed component 1 and is connected to the moving component 2, and can drive the moving component 2 to make reciprocating motion in the fixed component 1;

[0044] During use, the motor controls the moving component 2 to move to the side with the powder inlet 4, and the powder falls from the powder inlet 4 and is stored in the equal compartment 3. Then the motor controls the moving component 2 to move to the side with the powder outlet 5 along the Figure 7 (A) arrow direction, and the powder falls from the equal compartment 3 through the powder outlet 5, and then moves to the side with the powder inlet 4 along the Figure 7 (B) arrow direction to receive the powder falling from the powder inlet 4, reciprocating to complete batching.

[0045] Compared with Embodiments 1 and 2, the fixed component 1 and the moving component 2 adopted in this embodiment have a smaller width and are more suitable for use in narrow spaces.

[0046] Embodiment 4

[0047] This embodiment is a supplement to other embodiments, mainly used to solve the problem that the number of material discharges and the total amount of discharged materials cannot be controlled.

[0048] In this embodiment, a control unit is further provided on the motor 7. The control unit is used to control the start and stop of the motor 7. When the equal - amount grid 3 filled with powder rotates to the powder outlet 5, the motor stops working. After all the powder has fallen from the powder outlet 5, the motor 7 is started again. The output of the powder can be controlled by controlling the start and stop of the motor 7.

[0049] A sensor 6 is further provided on the fixed component 1, and a sensor trigger point 9 is also provided on the contact end of the equal - amount grid 3 and the powder outlet 5. The sensor 6 is arranged at the left and right ends of the fixed component 1 located at the powder outlet. The sensor 6 is used to judge whether the equal - amount grid 3 reaches the powder outlet 5, assist the control unit to control the start and stop of the motor 7, and then record the number of powder discharges, so as to calculate the total amount of powder distribution. Specifically, to control the total amount of output powder, let the amount of powder that the equal - amount grid can hold be x, unit: gram, the number of start - stop times of the motor be: t, and the total amount of output powder be: A, unit: gram. Then the total amount of output powder A is

[0050] A = x×t

[0051] When the user needs to control the number of material discharges, the sensor 6 can also transmit the recorded number of powder discharges to the control unit. The control unit can control the start and stop of the motor. When the preset number of material discharges is reached, the control unit can control the motor 7 to stop running.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
