Description
Technical field
The utility model relates to a kind of beverage extraction plant, relates in particular to a kind ofly in order to drive the drives structure that in beverage extraction plant, moving part moves forward and backward, and beverage extraction plant can be coffee machine or other similar devices.
Background technology
Coffee machine is a kind of machine of preparing coffee beverage, the legacy device of coffee machine includes water pot, heating element heater and water pump etc., during use, the capsule that is equipped with ground coffee is placed in coffee machine, during use, by drives structure, two parts in coffee machine are closed up and form extraction chamber again, now coffee capsule is positioned at extraction chamber, during extraction, the water of heating is got in extraction chamber with water pump again, water flows through the coffee raw material that will extract, and coffee beverage 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 with closed in coffee machine with the drives structure of opening two parts:
A kind of is handle and connecting rod drive-type, as a patent No. be ZL00812101.X (notification number is CN1263415Y) mono-kind of Chinese invention patent < < for prepare the device > > of beverage extracting substance disclosed so a kind of parts drives structure of handle and connecting rod drive-type, it comprises closed bar and two draw bars with both arms, two arms of closed bar are fixed on the first pivot of the both sides that are positioned at described the second parts and can rotate around it, draw bar is fixed on the second pivot of the both sides that are positioned at the second parts and can rotates around it, together with the end of two arms of draw bar and closed bar firmly fixes by the 3rd rotatable pivot, so that co-operating makes device closure and opens 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 placing coffee capsule, handle is upwards pulled angled, handle perk, occupy larger height, this coffee machine need be placed on the position with certain altitude space, 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, the packet sending and falling structure > > that is a Chinese utility model patent < < beverage brewing device of ZL201020113007.1 (notification number is CN201617680U) as the patent No. has disclosed a kind of hydraulic drive type drives structure, comprise on the rear wall of support and be fixed with interior holder, on this interior holder, have the rear intake tunnel axially running through, the rear chamber in the second parts with open rearward end, the rear chamber of the second parts is movably set on interior holder and internally holder front and back slippage mutually, and between rear chamber's internal perisporium of the outer peripheral face of interior holder and the second parts for liquid sealing coordinates, on the second parts, be also provided with the liquid outlet channel that is communicated with the cavity on extraneous and described the second parts, in the pilot hole of installation portion, there is interior omoplate, on each lead, be 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, has described in connection and brewage space and extraneous advancing water passage on described the first parts.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 the beverage maker of existing no matter which kind of type of drive, the pattern of two parts relative motions is, the relative support of one of them parts is fixed, the relative support slippage of another parts, it is very long that mobile parts slide onto total mobile route of extraction state, owing to driving impeller that removable parts move to be directly fixed on the rear portion of removable parts, drives structure directly drives parts or impeller slippage, movably impeller is piston piece in hydraulic-driven structure, therefore the distance that piston piece will move is identical with the closed distance that will move of removable parts, cause the shift motion of piston also very long, this will certainly extend the waiting time that beverage extraction plant (as coffee machine) is prepared beverage (as coffee), inefficiency.
Utility model content
Technical problem to be solved in the utility model is the parts connecting rod drives structure that the beverage extraction plant of a kind of energy fast driving parts reach is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of parts connecting rod drives structure of beverage extraction plant, comprise the support with dress bag mouth and the mouth of substitute and the parts that are constrained in energy front and back slippage in support, it is characterized in that: in described support, also retrain the movable part that has energy front and back slippage, this movable part is positioned at the rear portion of parts, between the rear portion of movable part and parts, by two bar linkage structures that are symmetrical set, be connected, described bar linkage structure comprises first connecting rod, second connecting rod and third connecting rod, one end of described first connecting rod is rotatably connected on a side of movable part, one end of described second connecting rod is rotatably connected on a side of support, the other end of first connecting rod is rotatably connected on the middle part of second connecting rod, the other end of second connecting rod and one end of described third connecting rod are rotationally connected, one side at the other end of described third connecting rod and described parts rear portion is rotationally connected.
