Description

Technical Field

[0001] This utility model relates to the field of intelligent beverage vending machines, specifically a coffee stirring and steam extraction device and its coffee machine. Background Technology

[0002] Coffee machines typically supply coffee powder to the mixing unit via a powder container assembly and inject hot water into the mixing unit via a water inlet assembly. After the mixing unit completes the mixing of the powder, the coffee is dispensed through the spout assembly. However, moisture can easily remain in the mixing unit, causing the coffee powder to clump. Chinese patent CN201076360Y discloses a coffee machine that uses a blower to remove moisture from the mixing cup. This coffee machine has the following problems:

[0003] 1) The blower is large and takes up a lot of space. If a small fan is used instead, there is a problem of insufficient suction.

[0004] 2) The blower draws air from both mixing cups simultaneously through the pipes, and cannot draw air from only one mixing cup, resulting in high energy consumption.

[0005] In addition, the top cover of the existing coffee machine feed container can be opened to replace the powder, but this poses a risk of the top cover opening accidentally, which will affect the sealing of the feed container. Utility Model Content

[0006] The purpose of this invention is to provide a coffee stirring and steam extraction device and a coffee machine thereof to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A coffee stirring and steam extraction device includes several stirring components and a steam extraction component connected to the stirring components.

Each branch steam extraction pipe 201 is connected to a stirring component 1 in a one-to-one correspondence. Both the first fan 202 and the second fan 203 are miniature fans. Both the first fan 202 and the second fan 203 can be controlled independently. When each stirring component 1 needs steam extraction, only the first fan 202 and the corresponding second fan 203 can be turned on, thus saving energy.

[0036] It is understood that in the above technical solution, the coffee stirring steam extraction device of this utility model is configured with a separate steam extraction branch pipe 201 with a built-in second fan 203 for each stirring component 1 for steam extraction. In addition, steam extraction is also performed on all steam extraction branch pipes 201 through a steam extraction main pipe 200 with a first fan 202, which not only ensures the suction power, but also avoids the problems of excessive blower size and noise.

[0037] Continue reading Figure 6 In one embodiment of the present invention, the stirring assembly 1 includes a stirrer 101 and a steam extraction cover 100 disposed on the upper end of the stirrer 101.
