Technical Field

[0001] The present application relates to the technical field of electrical equipment for brewing coffee, and in particular to a retractable powder feeding component and a coffee machine. Background Art

[0002] A fully automatic coffee machine is an appliance that can at least realize the entire process of brewing coffee, including pressing powder, brewing, and removing residues. During use, the brewing unit of the coffee machine moves to the coffee powder adding position to add coffee powder, and then moves to the extraction position to complete coffee extraction. After coffee extraction is completed, the coffee powder cake is pushed out of the brewing unit and the powder cake is swept away, and finally returns to the initial position.

[0003] However, in general coffee machines, in order to avoid the brewing unit or the grinder space, the powder channel is often designed to be very long, and the brewed material is easy to remain on the powder channel, increasing the risk of blocking the powder channel. As time goes by, the waste remaining on the powder channel is easy to deteriorate and mold, which affects the personal health of the user. Utility Model Content

[0004] The present application provides a retractable powder feeding assembly and a coffee machine, wherein the powder feeding channel can reduce the problem of excessive residual waste in the powder feeding channel caused by the powder feeding channel being too long.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] Reference Figure 1 The embodiment of the present application discloses a retractable powder lowering component, which is used in a coffee machine and is used to add coffee powder to a brewing unit 2 in the coffee machine. There is a working chamber 1 in the coffee machine. In the embodiment of the present application, the brewing unit 2 moves linearly in the working chamber 1 under the drive of a driving unit in the coffee machine. During the use of the coffee machine, the brewing unit 2 first moves to a powder receiving position, and coffee powder is added to the brewing unit 2 through the powder lowering component. After the powder is received, the brewing unit 2 continues to move linearly. This process requires the powder lowering component to move and give way to the brewing unit 2.

[0029] Reference Figure 1 and Figure 2 The powder lowering assembly described in the present application includes a fixed bracket 3, a powder lowering channel 4 and a tension spring 5.

[0030] The powder lowering channel 4 is slidably connected with the fixed bracket 3 along the feeding direction, and the feeding direction is the direction in which the coffee powder enters the brewing unit 2 from the external powder making mechanism of the coffee machine. The feeding direction in the coffee machine is as follows: the powder lowering channel 4 extends downwardly from the side wall of the coffee machine to the direction of the moving path of the brewing unit 2. When the brewing unit 2 moves to the powder receiving position, the coffee powder enters the brewing chamber of the brewing unit 2 through the powder lowering channel 4. After the coffee powder is added, the powder lowering channel 4 slides along the fixed bracket 3 to make way for the movement of the brewing unit 2.

[0031] By arranging the powder lowering channel 4 to be slidably connected to the fixed bracket 3, the setting length of the powder lowering channel 4 can be reduced, thereby reducing the problem of excessive residual waste in the powder lowering channel 4 caused by the powder lowering channel 4 being too long.

[0032] In a preferred example, two fixed brackets 3 are provided, and the two fixed brackets 3 are symmetrically arranged on both sides of the powder lowering channel 4; in another example, the two fixed brackets 3 are connected as one. The powder lowering channel 4 is connected to the fixed bracket 3 via a tension spring 5. When the coffee powder is added, the brewing unit 2 continues to move upward, and the brewing unit 2 pushes the powder lowering channel 4 to overcome the elastic force of the tension spring 5 and slide relative to the fixed bracket 3.

[0033] The fixed bracket 3 is provided with a slide groove 31 , and the powder lowering channel 4 is provided with a slide rail 41 matched with the slide groove 31 . The powder lowering channel 4 is slidably connected with the fixed bracket 3 via the slide rail 41 and the slide groove 31 .

[0034] The lower powder channel 4 is provided with an abutment portion 42 at the feed opening, and the abutment portion 42 is located at the end of the slide rail 41. When the lower powder channel 4 is driven by the tension spring 5 to slide downward along the slide groove 31, the abutment portion 42 can limit the lower powder channel 4 to prevent the slide rail 41 from being separated from the slide groove 31. In a preferred example, the abutment portion 42 is a flange integrally provided at the feed opening of the lower powder channel 4.

[0035] Furthermore, in order to improve the structural strength of the powder lowering channel 4 , a reinforcing rib 43 is further provided on the side wall of the powder lowering channel 4 .

[0036] The fixed bracket 3 is fixedly connected to a lower fixed hook 32, the abutting portion 42 is fixedly connected to an upper fixed hook 44, and both ends of the tension spring 5 are respectively connected to the lower fixed hook 32 and the upper fixed hook 44. Under the elastic action of the tension spring 5, when the lower powder channel 4 is in the initial position, the outlet of the lower powder channel 4 is located on the moving path of the brewing unit 2, so that the coffee powder can enter the brewing chamber from the lower powder channel 4.

[0037] In a preferred embodiment, referring to Figure 2 and Figure 3 , the bottom of the outlet of the lower powder channel 4 is provided with an inclined lower powder channel tongue 45, and the lower surface of the lower powder channel tongue 45 is a smooth surface. The brewing unit 2 is fixedly provided with a powder channel top block 21 that cooperates with the lower powder channel tongue 45. After the addition of coffee powder is completed, the brewing unit 2 moves upward, and the powder channel top block 21 abuts against the lower powder channel tongue 45, thereby pushing the lower powder channel 4 to slide upward along the slide groove 31, so that the lower powder channel 4 forms a movement to give way to the brewing unit 2. After the powder channel top block 21 moves to the outlet position of the lower powder channel 4, the brewing unit 2 continues to move upward, and the outlet of the lower powder channel 4 abuts against the side wall of the brewing unit 2 and slides relative to the brewing unit 2 along the side wall of the brewing unit 2.

[0038] In another preferred example, referring to Figure 4The lower powder channel tongue 45 is provided with a lower powder protrusion 451 on one side facing the brewing unit 2. The lower powder protrusion 451 is arranged at the bottom of the lower powder channel tongue 45. The lower powder protrusion 451 is in an arc-shaped structure protruding toward the brewing unit 2 from top to bottom. When the coffee powder is added, the brewing unit 2 continues to move upward, and the powder channel top block 21 first abuts against the lower powder protrusion 451. Since the lower powder protrusion 451 is in a convex arc-shaped structure, when the powder channel top block 21 moves from the lower powder protrusion 451 to the upper part of the lower powder protrusion 451, the moving speed of the lower powder channel 4 will suddenly change, thereby forming the vibration of the lower powder channel 4, so that the excess coffee powder in the lower powder channel 4 can enter the brewing unit 2 through the vibration; when the brewing unit 2 moves downward through the lower powder channel 4, the powder channel top block 21 moves from the upper part of the lower powder protrusion 451 to the lower powder protrusion 451, and the lower powder channel 4 will also vibrate, thereby further reducing the amount of waste remaining in the lower powder channel 4.

[0039] In addition, the present application also discloses a coffee machine, in which the retractable powder lowering component is arranged.

[0040] The working principle of the embodiment of the present application is as follows: when it is necessary to brew coffee, the brewing unit 2 first moves to the powder receiving position, at which time the coffee powder enters the brewing chamber in the brewing unit 2 through the lower powder channel 4; after the powder receiving is completed, the brewing unit 2 continues to move upward, and the powder channel top block 21 and the lower powder channel tongue 45 push the lower powder channel 4 to overcome the elastic force of the tension spring 5 and slide upward, thereby making way for the movement of the brewing unit 2; when the coffee extraction is completed, the brewing unit 2 moves downward, and after the brewing unit 2 passes through the lower powder channel 4, the lower powder channel 4 is reset under the elastic force of the tension spring 5.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
