Background technique
As the improvement of people's living standards, coffee beverage starts to be liked by people, and becomes people and especially chase after
Seek the daily drinks of quality of the life person.The production method of current coffee beverage mainly has: using instant formula coffee brewing, using
Existing ground coffee oneself carries out brewed in coffee machine and grinds coffee bean and further brewed etc. using coffee machine scene.
Above-mentioned coffee machine has heat generating device usually to heat to the water for flowing through the heat generating device, and will be heated
Hot water shower to ground coffee on brew obtained coffee beverage.
As shown in Figure 1, as a kind of schematic cross-section of the coffee machine of the prior art, it is special to be disclosed in Chinese utility model
In benefit application the 201020553983.9th (Authorization Notice No. is 201861447 U of CN).The coffee machine includes that main body (is not schemed
Show), water tank 1, float trap 2, container 3, water inlet silicone tube 4, heat-generating pipe 5, check valve 6, the fixed bracket 7 of float trap, water outlet silica gel
Pipe 8 and U-bend 9 etc..The heat-generating pipe 5 is tightly attached on the U-bend 9, to provide heat to the U-bend 9 in heating power
Amount.
The working principle of the coffee machine shown in FIG. 1 is: quantitative water is added to water tank 1, due to the pressure of water in water tank 1
It acts on and washes float trap 2 open, water flows into container 3, and the floating of float trap 2 under the buoyancy of water in container 3 blocks water tank 1
Collector nozzle, the water in container 3 washes check valve 6 open under atmospheric pressure, and water is heated by U-bend 9, from U-bend 9
Water outlet stream by water outlet silicone tube 8 and fill the funnel of ground coffee, the coffee beverage being brewed to finally flows in glass.
This heat generating device being combined by heat-generating pipe 5 and U-bend 9 is that (what is generallyd use is electricity to general electrothermal tube
Hinder heating coil), since the fitting between its heat-generating pipe 5 and U-bend 9 is difficult to reach close contact and heat-generating pipe 5 not
