Abstract
Description
Technical Field
[0001] The utility model relates to the field of coffee machines, in particular to a coffee powder transfer device inside a coffee machine. Background Art
[0002] During the process of brewing coffee in a coffee machine, after grinding coffee beans into coffee powder by a grinding device, it is necessary to transfer the ground coffee powder inside the coffee machine to a pressing and brewing device for pressing and brewing. However, the existing powder dropping mechanism for coffee powder requires a certain height difference. However, with the continuous miniaturization of household and commercial coffee machines, the layout of each functional unit inside the machine body is becoming more and more compact, and the space inside the machine body that can provide a height difference is getting smaller and smaller. Therefore, technicians in this field are committed to developing a device that can transfer coffee powder between different functional units inside a coffee machine under the conditions of a small height difference and a short distance. Summary of the Utility Model
[0003] To achieve the above object, the utility model provides a coffee powder transfer device inside a coffee machine, including: an L-shaped housing, which includes a vertical section cavity and a horizontal section cavity inside the L-shaped housing; a powder inlet for coffee powder is provided at the top of the vertical section cavity, and the coffee powder enters the vertical section cavity from the powder inlet and falls into the horizontal section cavity through the vertical section cavity; the horizontal section cavity includes two connected first circular cavities and second circular cavities; a first runner is provided in the first circular cavity, and a second runner is provided in the second circular cavity, and the first runner and the second runner are driven to rotate by a reduction gear set; the coffee powder falling into the horizontal section cavity through the vertical section cavity is first transported into the first circular cavity by the rotation of the blades of the first runner, then transported into the second circular cavity by the rotation of the blades of the second runner, and finally output from the powder outlet.
[0004] Further, the first runner and the second runner are of the same size, each runner only includes two blades, and the rotation speeds of the first runner and the second runner are set to be the same or an integer multiple by the reduction gear set.
[0005] Further, the rotation speed of the second runner is not lower than that of the first runner to prevent coffee powder from accumulating in the horizontal section cavity.
[0006] The coffee powder transfer device provided by the utility model can realize the short-distance horizontal transportation of coffee powder inside the coffee machine under the condition of a low height difference.
[0007] The following will further illustrate the concept, specific structure and technical effects generated by the utility model with reference to the drawings, so as to fully understand the purpose, features and effects of the utility model. Description of the Drawings
[0008] Figure 1 is an internal view of the coffee powder transfer device inside the coffee machine of the present utility model;

[0010] The following introduces multiple preferred embodiments of the present utility model with reference to the accompanying drawings of the specification to make its technical content clearer and easier to understand. The present utility model can be embodied in many different forms of embodiments, and the protection scope of the present utility model is not limited to the embodiments mentioned in the text.
[0011] In the drawings, components with the same structure are denoted by the same numerical reference signs, and components with similar structures or functions everywhere are denoted by similar numerical reference signs. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model does not limit the size and thickness of each component. To make the illustration clearer, the thickness of some parts in the drawings is appropriately exaggerated.
[0012] As shown in FIGS. 1-2, the coffee powder transfer device inside the coffee machine according to the present utility model includes an L-shaped housing 1. Inside the L-shaped housing 1, there is a vertical section cavity 12 and a horizontal section cavity. At the top of the vertical section cavity 12, there is a powder inlet 11 for coffee powder. The coffee powder enters the vertical section cavity 12 of the L-shaped housing 1 through the inlet 11 and then falls into the horizontal section cavity via the vertical section cavity 12. The horizontal section cavity includes two connected first circular cavities 13 and second circular cavities 14. A first runner 2 is provided in the first circular cavity 13, and a second runner 3 is provided in the second circular cavity 14. The first runner 2 and the second runner 3 are driven to rotate by a reduction gear set 4. In this embodiment, the first runner 2 and the second runner 3 are of the same size, and each runner only includes two blades. The rotation speeds of the first runner 2 and the second runner 3 are set to be the same or an integer multiple through the reduction gear set, so that the blades of the two runners will not interfere with each other during rotation.
[0013] The coffee powder that falls into the horizontal section cavity through the vertical section cavity 12 is conveyed by the rotation of the first runner 2, enters the second circular cavity 14 through the first circular cavity 13, and then is conveyed by the rotation of the second runner 3 and output from the powder outlet 15.
[0014] In order to prevent the coffee powder from accumulating in the horizontal section cavity, on the premise that the first runner 2 and the second runner 3 are of the same size, the rotation speed of the second runner 3 should not be lower than that of the first runner 2.
[0015] The coffee powder transfer device provided by the present utility model can realize the short-distance horizontal transportation of coffee powder in the coffee machine under the condition of low head.
[0016] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
