Description
Technical field
The invention belongs to the technical field of coffee machine, particularly relate to a kind of hydraulic-driven structure driving moving part movement in coffee machine.
Background technology
Coffee machine is a kind of machine preparing coffee beverage, the legacy device of coffee machine includes water pot, heating element heater and water pump etc., during use, the capsule being equipped with ground coffee is placed in coffee machine, during use, by drives structure, two parts in coffee machine are closed up formation extraction chamber again, now coffee capsule is positioned at extraction chamber, is got to by the water water pump of heating in extraction chamber during extraction again, water flows through the coffee raw material that will extract, and coffee beverage then flows to cup from the outlet pipe of coffee machine.
Existing beverage maker mainly contains two kinds of forms as driven two parts to move in coffee machine with drives structure that is closed and that open two parts:
One is handle and connecting rod drive-type, a kind of parts drives structure of handle and connecting rod drive-type as disclosed in the patent No. Chinese invention patent " a kind of device in order to prepare beverage extracting substance " that is ZL00812101.X (notification number is CN1263415Y), it comprises the closed bar and two draw bars with both arms, the first pivot that two arms of closed bar are fixed on the both sides being positioned at described second parts can rotate around it, the second pivot that draw bar is fixed on the both sides being positioned at the second parts can rotate around it, together with the end of draw bar and two arms of closed bar is firmly fixed by the 3rd rotatable pivot, so that co-operating makes device close and open mutually.
The parts drives structure of handle and connecting rod formula relates to the many complex structures of parts, during use, need upwards pull or press down handle, before placement coffee capsule, handle be upwards pulled angled, handle tilts, occupy larger height, this coffee machine need be placed in there is certain altitude space position on, could use, to coffee machine to lay space requirement high, use not humane.The parts drives structure of existing handle and connecting rod formula realizes the locking of two parts by bar linkage structure in addition, for preventing leaking in extraction process, coffee machine has higher coupling mechanism force requirement to two parts, like this after two parts close up, because the coupling mechanism force between two parts is very large, as will be again opened two parts, needing more energetically could pulling handle, operation effort.
Another kind is hydraulic drive type, a kind of hydraulic drive type drives structure as disclosed in the patent No. Chinese utility model patent " a kind of packet sending and falling structure of beverage brewing device " that is ZL201020113007.1 (notification number is CN201617680U), the rear wall comprising support is fixed with internal fixtion seat, this internal fixtion seat has the rear intake tunnel axially run through, there is in second parts the rear chamber of open rearward end, the rear chamber of the second parts to be movably set on internal fixtion seat and can slippage before and after internal fixtion seat relatively, and for liquid sealing coordinates between the outer peripheral face of internal fixtion seat and rear chamber's internal perisporium of the second parts, second parts are also provided with the liquid outlet channel of the cavity be communicated with on extraneous and described second parts, in the pilot hole of installation portion, there is interior omoplate, each lead is also arranged with back-moving spring, one end of this back-moving spring is resisted against on the antetheca of support, the other end of back-moving spring is resisted against on the interior omoplate in described pilot hole, described first parts has described in connection and brewages space and extraneous advancing water passage.
Hydraulic-driven structure is equivalent to handle and connecting rod drives structure and has the advantages such as structure is relatively simple, coupling mechanism force is strong, easy to operate, space hold is few.In existing hydraulic-driven structure, piston structure is formed between the rear chamber of internal fixtion seat and the second parts, when high-pressure cold water from after intake tunnel enter internal fixtion seat front end face and the second parts rear chamber between form plunger shaft in column, high-pressure cold water needs to be full of whole plunger shaft could promote the elastic force reach that the second parts overcome back-moving spring, the space occupied due to plunger shaft is larger, it is long that high-pressure cold water is full of plunger shaft required time, this will certainly affect the waiting time of coffee machine extraction coffee, waiting time approximately needs more than 40 second, inefficiency.Therefore existing hydraulic-driven structure also can be further improved.
