The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 3; The water route switching valve of this coffee machine comprises valve body 1 and valve gap 2, and the push rod 10 that has spring 30 is arranged in the cavity of valve body 1; Sealing ring is set on the push rod 10; Valve body 1 is provided with the hose nozzle that communicates with cavity more than two, and sealing ring is more than three, and sealing ring is along the axial setting of push rod 10; Adjacent two sealing rings are divided into cavity the chamber of a relative closure jointly with push rod 10, and all hose nozzles that are positioned at same chamber are interconnected.
One end of push rod 10 is crimped on the spring 30, and an end of the other end of push rod 10 and power transmission shaft 11 joins, and the other end of power transmission shaft 11 is socketed in the push rod cup 12, and push rod cup 12 is slidingly installed in the valve gap 2.
Be provided with the step more than two on the inwall of valve gap 2 vertically, the end of step is provided with the inclined-plane, is provided with guide chute 2.1 between the step; Towards being arranged with guiding tooth 12.2, the middle and lower part of push rod cup 12 is provided with outstanding last guide pad 12.1 along circumferentially in the bottom of push rod cup 12; Last guide pad 12.1 is slidingly installed in the guide chute 2.1; The middle and lower part of power transmission shaft 11 is provided with following guiding tooth 11.1 outstanding more than up; Under lead tooth 11.1 join with last guiding tooth 12.2.Under lead tooth 11.1 and last guiding tooth 12.2 engagement location.
In the present embodiment, sealing ring has three, is respectively first sealing ring, second sealing ring and the 3rd sealing ring; First sealing ring, second sealing ring and the 3rd sealing ring are with the push rod 10 common chambers that cavity are divided into two relative closures.Hose nozzle has three, is respectively first hose nozzle, second hose nozzle and the 3rd hose nozzle.Water route switching valve in the present embodiment is the structure of one-in-and-two-out.
Following guiding tooth on the power transmission shaft 11 can be distinguished snap-lock with the inclined-plane of guiding tooth and valve gap 2 on the push rod cup 12 during different axial location in valve gap 2.When push rod 10 moved in valve body 1, the chamber of above-mentioned sealing also moved vertically, the hose nozzle of diverse location is communicated with or closes, and reached the function in conversion water route.
The course of work of the utility model is: the first step: under original state; Two hermetic cavity chambers have been constituted at valve body 1 and push rod 10 and sealing ring 20; The chamber of left end has included only first hose nozzle, therefore is equivalent to sealed, and the chamber of right-hand member has comprised second hose nozzle and the 3rd hose nozzle; This moment, second hose nozzle and the 3rd hose nozzle were connection, saw Fig. 2.
Second step: apply external force and press push rod cup 12, move a segment distance after push rod cup 12 drives power transmission shaft 11 and push rod 10, and compression spring 30; After external force removes under the elastic force effect of spring 30; The following guiding tooth of power transmission shaft 11 is being fixed up at the step place after angle of rotation on the inclined-plane of the step of valve gap 2, and push rod 10 is pinned in the position of confirming, this moment, the sealed chamber of left end included first hose nozzle and second hose nozzle; Promptly first hose nozzle and second hose nozzle are what be communicated with; And the chamber of right-hand member has included only hose nozzle C, is equivalent to sealed, and sees Fig. 3.
The 3rd step: apply external force once more and press push rod cup 12; Push rod cup 12 moves a segment distance after continuing to drive power transmission shaft 11 and push rod 10; And compression spring 30, under the elastic force effect of spring 30, the following guiding tooth of power transmission shaft 11 enters in the guide chute of valve gap 2 after on the inclined-plane of the step of valve gap 2, rotating an angle again after external force removes; Spring 30 promotes push rod 10 and is returned to initial position and pinning; It is obstructed that revert to first hose nozzle this moment, and the original state that second hose nozzle and the 3rd hose nozzle are communicated with is seen Fig. 2.More than be a complete operation cycle, can be communicated with by the different water route of this Cyclic Selection.
