Description
Technical field
The present invention relates to a kind of beverage extraction plant, particularly relate to a kind of parts opening/closing system for beverage extraction plant, wherein, beverage extraction plant can be coffee machine.
Background technology
A patent No. is had to be that the Chinese invention patent " a kind of device in order to prepare beverage extracting substance " of ZL00812101.X (notification number is CN1263415C) discloses so a kind of device, it comprises the first parts fixed and second parts that can rotate around a rotating shaft relative to the first parts, described rotating shaft is positioned at the rear portion of described two parts, the front portion of each parts is provided with cavity, to hold the material be extracted, this device also comprises the system that can close and open two parts, described system has closed bar and two draw bars of 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 described first 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, in the closing position of two parts, described first, second and the 3rd pivot be located substantially on same vertical plane, and described vertical plane is positioned at the rear portion of the cavity holding extracting substance.Although this device overcomes the defect of coffee machine in international patent application WO94/02059, reaching fixed member can the object of effective locked upper parts, just because of when two parts close up, first, second and the 3rd pivot be located substantially on same vertical plane, and vertical plane is positioned at the rear portion of the cavity holding extracting substance, and two arms of closed bar are directly connected with draw bar, therefore in opening procedure, by the both arms of closed bar, draw bar is directly passed to the power that closed bar applies, this tangential thrust passing to draw bar is less, tangential thrust is the main power of unlatching two parts, therefore this device needs larger power could open two parts, two parts do not have power-assisted in opening process simultaneously, the feel of opening is poor.Aforementioned means is for ensureing good coupling mechanism force in addition, and the vertical plane that its first, second, and third pivot is formed is positioned at the rear portion of the cavity holding extracting substance, and this also can cause the length of whole device long, is unfavorable for the miniaturization of product.Because closed bar is directly connected with rotation draw bar, therefore under two parts full open position, the angle that two parts open is less, it can only place less coffee capsule between two parts, there is a kind of spherical coffee capsule in the market, the volume of this coffee capsule and whole height are comparatively large, as opening angle between two parts is too small, are unfavorable for the coffee capsule of this relatively large volume to be placed between two parts to extract.
In sum, existing such parts on-off structure still has the necessity improved further.
Summary of the invention
Technical problem to be solved by this invention provides a kind of structural design the more rational parts opening/closing system for beverage extraction plant for above-mentioned prior art present situation, this opening/closing system not only can strengthen the opening angle between two parts, can ensure again simultaneously unlatching two parts comparatively position be labour-saving advantage.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of parts opening/closing system for beverage extraction plant, comprise fixed member and moving part, the rear portion of these two parts is linked together by an axis of rotation, two parts close rear formation in order to hold the extraction chamber being extracted material, and between fixed member and moving part, be provided with the connecting rod drives structure in order to close and to open these two parts; It is characterized in that: described connecting rod drives structure comprises the handle with two actuating arms, the upper end of two actuating arms of handle is connected on fixed member by the first pivot, and the lower end of actuating arm is connected with connecting rod by the second pivot; Two draw bars, the lower end of draw bar is connected to the both sides of fixed member by the 3rd pivot; Two levers, the middle part of lever is connected on moving part by the 4th pivot, and the upper end of lever is rotationally connected by the upper end of Wushu axle and described draw bar, and the lower end of lever is rotationally connected by the other end of the 6th pivot and described connecting rod.
As improvement, in the closing position of described fixed member and moving part, described 3rd pivot, the 4th pivot and Wushu axle are generally within same vertical plane, and described vertical plane is positioned in order to hold the middle part being extracted the extraction chamber of material, and described 6th pivot is positioned at the rear portion of described vertical plane.Like this after two parts are closed, dead point can be formed, ensure form good coupling mechanism force between two parts, in extraction process, even if there is larger hydraulic pressure to act between fixed member and moving part, because forming dead point between each rod member, two parts can be locked, can not be forced the danger of upspringing under hydraulic pressure effect; Vertical plane is positioned in order to hold the middle part being extracted the extraction chamber of material in addition, and allowing use has the coffee machine overall dimensions of this opening/closing system to diminish, and is beneficial to the miniaturization of coffee machine.
As improvement, linked together by connecting rod between above-mentioned two connecting rods.Connecting rod connects two connecting rods makes two connecting rod energy synchronization actions, guarantees the stationarity that two parts are opened.
The two ends of above-mentioned draw bar are bend forward shape.
Integral piece is formed together with above-mentioned handle is one-body molded with actuating arm.
For providing a power-assisted to two parts in opening process, the rear portion between above-mentioned fixed member and moving part is provided with and makes two parts keep certain elastic component opening elastic force.Like this unlatching can be made lighter, feel is better.
Above-mentioned elastic component is two torsion springs, and torsion spring set is located at the end of described rotating shaft, and one end of torsion spring is plugged in the jack at fixed member rear portion, and the other end of torsion spring is plugged in the jack at moving part rear portion.Certain elastic component also can be spring, and the two ends of spring hook in the jack on two parts respectively.
Compared with prior art, the invention has the advantages that: be not directly be connected between draw bar and the both arms of handle, but be connected with connecting rod by lever, lever and connecting rod can lengthen the connection distance between draw bar and handle, and after two parts are opened, the opening angle between two parts strengthens, the larger coffee capsule of volume can be applicable to, meanwhile, also make increase place the space of capsule, facilitate the placement of capsule; Have the setting by connecting rod and lever again, in handle opening process, connecting rod is large to lever tangential force forward, can more easily open two parts, ensure good feel.
