Bottled water automatic feeding water water route -- operation principle：
Handle 13 on tap pushes closing and closes in water state, bottled water 1 water, and water pump 8 is normally carried out work of drawing water, water pump
8 power of drawing water can overcome the power of the spring 21 in check valve 4；The water that now water pump 8 is taken out makes coffee for the water in bottled water
Coffee drink；Another effect of check valve 4 is also to prevent the aqueous reflux of water tank 9 in bottled water.The version of check valve 4 can be various
Form, and the model of various other plastic cement, five metals, function is and prevents aqueous reflux, can be opened normal by the less draft of water pump 8
Water flowing.This water route principle also can replace tap with magnetic valve（13）, with software control switching water flowing and Guan Shui, realize bottled water
Water supply with Water in Water Tank switches.
Water tank automatic feeding water water route -- operation principle：
Handle 13 on tap pushes opening water flowing state, has water in bottled water 1, and water pump 8 is normally carried out work of drawing water；Now
The water that water pump 8 is taken out makes coffee beverage for the water in water tank；The reason for this kind of state water pump will not take out bottled water is to need
Overcome the power of the spring 21 in the component of check valve 4, as long as and have water in water tank 9, the water of slight pressure will be provided with to water pump,
Water pump can be taken out and make coffee beverage with the water of water tank 9.This water route principle also can replace tap 13 with magnetic valve, be cut with software control
Water flowing and Guan Shui are changed, realizes that bottled water switches with the water supply of Water in Water Tank.
Wherein, described faucet assembly, including：Sebific duct 11 is connect soon;Faucet assembly 12, assembled inside contains moving block
17；Handle 13；Screw 16；Wherein handle 13 can make non-standard component, you can suitably be adjusted by different appearance requirements；Water
The two ends of faucet assembly 12 are connected for fast joint form with connecing sebific duct 11 soon and can carry out fast insert-pull；The screw 16 of handle 13
It is locked on moving block 17；The version that handle 13 may also be employed button bit with moving block 17 is connected；
Tap operation principle：The water flowing of opening of the control faucet assembly 12 of manual toggle handle 13 closes the state of water with closing,
The component of check valve includes：Water inlet end connector 18；Sealing ring 19；Movable sealing block 20；Spring 21；Water outlet end connector 22；
Non-return valve operational principle：When end connector 18 of intaking has water, when water outlet end connector 22 has pumping for water pump to work, water pump is taken out
Waterpower can overcome the power of spring 21, make water reach water outlet end connector 22 from water inlet end connector 18, so as to realize that pumping for water pump works
Action；When water pump does not draw water, spring 21 can promote movable sealing block 20 to move toward water inlet end connector 18 with sealing ring 19, from
And realize that water will not flow backwards；Water inlet end connector 18 can be by ultrasonic wave connection with water outlet end connector 22, or button bit adds sealing ring
Version connects, and makes complete sealing；Sealing ring 19 can be fixed on movable sealing block 20, also may be selected solid
It is scheduled on on water end connector 18.
Therefore, the present invention has advantages below：The water supply of achievable bottled water 1 is cut with the way of supplying water of machine itself water tank 9
Change, the hand gear that coffee machine is mutually switched using bottled water 1 or the water automatic feeding water of water tank 9 is realized, so as to lift whole coffee
The Consumer's Experience effect of machine, enhances the sense directly perceived of user.
Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, it is every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
