Fully automatic liquid path conversion equipment and coffee machineTechnical field
The utility model relates to a kind of fully automatic liquid path conversion equipment and coffee machine.
Background technology
Existing coffee machine is more and more universal, no matter in family or business, is seen everywhere.But the fluid path in existing pressure coffee machine is generally controlled with magnetic valve or hand control valve.If magnetic valve is controlled, expensive price, is to be generally used on high-grade machine.If hand control valve controls, inconvenient operation, especially, in milk making or while beating steam, first revolves and starts in the past machine, and after having worked, cycle carrys out pressure release again.
The knob type liquid passageway converting device that Chinese patent literature CN201223302Y discloses a kind of pressure coffee machine on April 22nd, 2009, comprise rotary switch and heating pot body, it is characterized in that being provided with between rotary switch and heating pot body knob water-flowing path conversion equipment, this device comprises valve body, in valve body, be provided with front chamber and rear chamber, front chamber is provided with import, rear chamber is provided with outlet, between front chamber and rear chamber, be provided with center-aisle, camshaft lays respectively at any one in front chamber and rear chamber with the piston with spring, piston middle part is crimped on center-aisle, piston one end is crimped on camshaft, camshaft and rotary switch join.Piston middle part is provided with limited step, and sealing ring one side pressure is connected on limited step, and opposite side is crimped on center-aisle, and piston one end is through center-aisle and camshaft crimping.This knob type liquid passageway converting device is Manual structure, transfers to and beat in steam course after making coffee, and needs user's manual rotation turn-knob, so make user not too satisfied.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, flexible operation, automaticity is high, cost of manufacture is low fully automatic liquid path conversion equipment and coffee machine, to overcome weak point of the prior art.
A kind of fully automatic liquid path conversion equipment by this object design, includes:
At least plural fluid path, transaxle, in order to switch the conducting of above-mentioned path or to close;
Motor, in order to drive this transaxle,
Fluid path switching signal circuit, is connected with this transaxle, in order to produce the electrical signals of this transaxle position;
Controller, the electrical signals sending in order to receive this circuit, and this selection of Motor ground of instruction rotates or stops operating, to realize the conducting of above-mentioned path or to close.
Further, fluid path switching signal circuit comprises swivel plate, and this swivel plate is connected with this transaxle in the mode that can rotate with this transaxle, and is provided with electric conductor sheet on this swivel plate.
Further, fluid path switching signal circuit comprises activation signal plate, and it includes at least two contact conductor pieces, and it contacts with above-mentioned swivel plate, forms circuit turn-on, and produce the electrical signals of this transaxle position with this electric conductor sheet.
Further, electric conductor sheet includes inner ring metal ring plate, and the outer ring becket being connected with this inner ring metal ring plate.
Further, activation signal plate includes circuit board, and the contact electric conductor sheet being electrically connected with it, and wherein this contact electric conductor sheet and this inner ring metal ring plate, outer ring becket are electrically connected or disconnect.
Further, circuit board layout has circuit, and this circuit one end and this controller are electrically connected, and the circuit other end contacts electric conductor sheet and is electrically connected with this.
Further, contact electric conductor sheet includes more than two.
A coffee machine, it includes above-mentioned arbitrary fully automatic liquid path conversion equipment.
The utility model adopts after above-mentioned technical scheme, and by the transaxle in the rotation drive fluid path conversion equipment of motor output shaft, thereby the water outlet port changing in fluid path conversion equipment opens and closes, and finally realizes the logical and disconnected of fluid path.
The utility model is by driven by motor fluid path conversion equipment, by controller, control motor, thereby the fluid path in realization control coffee machine is logical and disconnected, operating in a key is quite simple, only need by function key, fluid path conversion equipment just can be screwed into corresponding position automatically, and coffee machine just can be realized corresponding function, comprises and makes coffee, beats steam, pressure release etc.; Can replace solenoid control fluid path completely, and low price.
The utlity model has simple and reasonable, flexible operation, automaticity is high, cost of manufacture is low feature.
Accompanying drawing explanation
Fig. 1 is the utility model one example structure schematic diagram.
Fig. 2 is the rear perspective schematic diagram of Fig. 1.
In figure: 1 is motor, 2 is fluid path conversion equipment, and 21 is fluid path, and 3 is swivel plate, and 31 is electric conductor sheet, and 4 is activation signal plate, and 41 is contact electric conductor sheet.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1-Fig. 2, this coffee machine, comprise fluid path conversion equipment 2, on this fluid path conversion equipment 2, be provided with two above fluid paths 21, also comprise motor 1 and pcb board, this pcb board comprises swivel plate 3 and activation signal plate 4, and fluid path conversion equipment 2 and swivel plate 3 join with the output shaft of motor 1, activation signal plate 4 setting corresponding to swivel plate 3, activation signal plate 4 is fixed on the body of coffee machine.
In the present embodiment, on swivel plate 3, be provided with more than one electric conductor sheet 31; On activation signal plate 4, be provided with more than one contact electric conductor sheet 41.
Motor 1 in rotation process, when the contact electric conductor sheet 41 on activation signal plate 4 carries out contraposition with the electric conductor sheet 31 on swivel plate 3, just provides the controller of signal to coffee machine with swivel plate 3, by whether stop motion of controller monitoring motor 1.
Principle based on same, when coffee machine will be realized certain function, first by controller, provide instruction, motor 1 just starts to rotate, while swivel plate 3, during electric conductor sheet 31 contraposition on contact electric conductor sheet on activation signal plate 4 41 and swivel plate 3, just feed back signal to controller, thereby realize fluid path 21 logical and disconnected of fluid path conversion equipment 2.
