Coffee brewing machine

Abstract

Provided is a coffee brewing machine, including a base frame with a spiral guideway, and a water supply mechanism arranged on the base frame. The water supply mechanism comprises a rotating shaft, a driving unit which drives the rotating shaft to rotate along a rotation center, a water outlet pipe passing into the rotating shaft, and a guiding element which is inserted on a guide hole of the rotating shaft and moves along a translation direction. The water outlet pipe is provided with a water outlet end which is driven by the guiding element to move along the spiral guideway when the rotating shaft rotates. The water outlet pipe can be further provided with two pipe sections which are connected with each other, wherein one pipe section rotates with the rotating shaft. The above structure can shorten motion path of the water outlet pipe in spiral water supply, and improves smooth property and use security of the coffee brewing machine in operation.

Description

technical field [0001] The present invention relates to a brewing machine, in particular to a coffee brewing machine suitable for brewing ground coffee. Background technique [0002] refer to figure 1 , 2 As shown, it is an existing coffee machine 1 that can brew ground coffee powder. The coffee machine 1 includes a base frame 11, and the base frame 11 includes a base 111 for placing the coffee pot, and a The base 111 is parallel to the top cover 112 up and down, and a column 113 connected between the base 111 and the top cover 112, and the coffee machine 1 also includes: a water tank 12 installed in the column 113, a line and the water tank 12 connected to the water outlet pipe 13, and a driving mechanism 10 that is installed on the top cover 112 and can drive a water supply end 131 of the water outlet pipe 13 to move spirally. The drive mechanism 10 includes a motor 14, a turntable 15 horizontally positioned in the top cover 112, a rotating shaft 16 interlocked with the...

Problems solved by technology

[0004] Although the existing coffee machine 1 can achieve the purpose of spiral water outlet through the cooperation of the above components, the structure of the coffee machine 1 is quite complicated and the production cost is relatively high

In the design of the water outlet, the outlet pipe 13 of the aforementioned coffee machine 1 protrudes from the side of the column 113 of the base frame 11, and is directly connected to the bottom of the moving part 182 through the bearing 19. In the process of water outlet, the outlet pipe 13 will be drawn by the moving part 182 to spirally surround, not only the outlet pipe 13 is easy to wrap around the outer periphery of the moving part 182, but also because the outlet pipe 13 is an exposed design, the The outlet pipe 13 is also easily scratched and broken by surrounding objects during use, causing hot water to flow out
