Abstract

The utility model relates to a hydraulic drive structure for a part of a beverage extraction device. The hydraulic drive structure comprises a base and the part. The hydraulic drive structure is characterized in that a piston part capable of sliding front and back is restrained in the base, the piston part is disposed at the rear of the part and is driven to move forward by the hydraulic drive structure, backward shifting resetting of the piston part is provided by a spring, and the piston part and a rear portion of the part are connected through a link structure. The piston part shifts forward and passes through the link structure, and then stroke of forward shifting of the part can be enlarged, that is to say, the hydraulic structure only needs to drive the piston part to shift forward for a short distance so as to enable the part to shift forward for a large distance, and accordingly the purpose of driving the part to shift forward quickly is achieved, working efficiency is greatly improved, water consumption during piston movement is reduced, piston stroke is greatly shortened, beverage outflow time is lowered, and working efficiency of the beverage extraction device is enhanced.

Description

The parts hydraulic-driven structure of beverage extraction plant

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 hydraulic-driven 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 piston piece that removable parts move to be directly fixed on the rear portion of removable parts, 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 be for above-mentioned prior art present situation, provide a kind of use less water under high pressure also can fast driving parts the parts hydraulic-driven structure of beverage extraction plant of reach.
