Description
Technical field
The utility model relates to a kind of parts of coffee machine, is specifically a kind of water feed apparatus of coffee machine.
Background technology
Coffee machine comprises frame and slide block, frame is provided with chute, slide block sliding fit is in chute, frame is provided with the rotating disk for driving slide block to move along chute, be on the circumference of rotating disk, to be hinged with one end of connecting rod, the other end and the slide block of connecting rod are hinged, rotate rotating disk, just can be through connecting rod band movable slider along chute slippage; Slide block top is provided with the chamber of brewageing of upper end open, and in frame, is provided with filter plate, and slide block rises to certain position and brewages chamber and just can hold out against with upper filter plate, brewages chamber sealing.On slide block, be fixed with one with the adapter of brewageing chamber and being communicated with, in frame, be fixed with a joint being communicated with water inlet pipe, when slide block rises while making to brewage chamber sealing, take over and be linked in the outer and adapter of joint and be communicated with docking with joint.As shown in Figure 1, joint 101 with the concrete docking structure of taking over 102 is: in the pipeline of joint 101, be provided with step surface 103 and spool 104, on step surface 103, be fixed with sealing ring 108, spool 104 pushes against and makes joint 101 sealings with the sealing ring 108 of step surface 103 under stage clip 105 effect, joint 101 is stretched out in the lower end of spool 104, take over and in 102, to be provided with one for by the top 106 on top on spool 104, when slide block rises to when forming sealing and brewageing chamber, take over 102 along with slide block rises and joint 101 fits, simultaneously, the top 106 of adapter 102 is also followed and is risen the spool of joint 101 104 jack-up, taking over 102 docks with joint 101, water inlet pipe 107 and brewage chamber and be communicated with.
Along with slide block rises, to brewage chamber sealing and joint and dock with adapter, water is brewageed chamber along with water inlet pipe, joint, adapter enter and is carried out coffee brewing.In brewing process, the indoor pressure of brewing cavity can progressively increase, likely slide block is pressed down, once slide block is pressed towards lower slider, also can follow decline with the adapter that slide block is fixing, and because joint is with to take over size all less, therefore again push against with the sealing ring of the step surface of joint under stage clip effect even if take over spool that one end distance that declines very little all can cause the top jack-up of being taken over, cause tab closure, make to brewage chamber and cut off the water supply.
Utility model content
The technical problems to be solved in the utility model is, a kind of water feed apparatus that can avoid brewageing in brewing process the coffee machine that chamber cuts off the water supply is provided.
Technical solution of the present utility model is, a kind of water feed apparatus of coffee machine is provided, it comprises the slide block of sliding fit in the chute of coffee machine frame and is arranged on the rotating disk for driving slide block to move along chute in coffee machine frame, slide block is provided with the chamber of brewageing of upper end open, in frame, be provided with the upper filter plate of brewageing chamber for sealing, on slide block, be fixed with and the adapter of brewageing chamber and being communicated with, in frame, be fixed with and be communicated with water inlet pipe and the joint for docking with adapter, on rotating disk, be fixed with concentric cam, water inlet pipe is provided with water intaking valve, in water intaking valve, be provided with step surface, on step surface, be fixed with seal washer, the spool of water intaking valve pushes against with the seal washer of step surface under action of reset spring, spool is provided with the top pushing against with cam, brewage under chamber closed state, take over joint fit and dock, simultaneously, cam backs down the spool of water intaking valve from the seal washer of step surface.
Adopt above structure coffee machine water feed apparatus compared with prior art, have the following advantages:
In brewing process, although along with the indoor hydraulic pressure of brewing cavity increases, slide block glides, make small angle of the reverse deflection of driven by rotary disc cam, make a bit of distance of top retraction, cause spool to move to step surface, because cam size is much larger with respect to joint and adapter, although finally cause spool to move to step surface therefore minimum deflection occurs cam, but the distance that spool moves is small, the seal washer of the spool after movement and the step surface of water intaking valve remains disengaging, water intaking valve can not seal, still the connection of water inlet pipe, therefore brewageing chamber while effectively having avoided brewageing cuts off the water supply.
