Abstract
The utility model belongs to the field of manufacturing technology of coffee machines, in particular to a piston of a coffee machine. The piston of the coffee machine comprises a shell body and a piston core mounted in the shell body. The piston of the coffee machine is characterized in that the piston and the piston core are connected with a rotating shaft for bearing the driving force of a connecting rod. The piston improves the traditional structure that two rotating shafts are respectively used for driving the shell body and the piston core into a structure that one rotating shaft is used for driving, solves the problem that the piston in the prior art has high possibility of deformation due to uneven stress and saves the materials.
Description
Technical field
The utility model belongs to coffee machine manufacturing technology field, is specifically related to a kind of coffee machine piston.
Background technology
The coffee machine piston is one of critical component of coffee machine, and the operation conditions of these parts is directly connected to coffee machine and normally uses.
Commercially available coffee machine piston is made up of housing and the piston core that is installed in the housing mostly, relies on two rotating shaft drives that connect piston core and housing respectively to move forward and backward, and there is following deficiency in this class formation:
Piston intensity is not high, unbalance stress, flexible type.
Summary of the invention
The utility model provides a kind of coffee machine piston, stressed evenly, intensity is high and the characteristics of dependable performance.
Concrete technology path of the present utility model is:
A kind of coffee machine piston comprises housing and is installed on the interior piston core of housing, it is characterized in that described piston and piston core are connected in a rotating shaft of accepting the connecting rod driving force.
Be provided with reset tension spring between described rotating shaft and housing.
Described reset tension spring is symmetrical arranged.
The utility model changes traditional structure that drives housing and piston core respectively by two rotating shafts into single rotating shaft drive, has solved the problem of the unbalance stress flexible type of prior art piston, has saved material.
Description of drawings
Fig. 1 is the utility model piston structure schematic diagram.
Fig. 2 is the utility model piston sectional structure schematic diagram.
Wherein: housing 1, piston core 2, rotating shaft 3, reset tension spring 4, water pipe 5, end 42, root 41.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Shown in Fig. 1-2, a kind of coffee machine piston, comprise housing 1 and the piston core 2 that is installed in the housing 1, described piston 1 is connected in a rotating shaft 3 of accepting the connecting rod driving force with piston core 2,1 of rotating shaft 3 and housing are provided with reset tension spring 4, described reset tension spring 4 should symmetry be provided with, and the end 42 and the root 41 of extension spring 4 can be hook or ring.
The motion process of piston is: when making coffee, rotating shaft 3 drives housings 1 and piston core 2 reaches, and water enters piston by pump by water pipe 5, because the pressure of pump is bigger, from the home position, piston core 2 keeps motionless to housing 1 by band, at this moment, and extension spring 4 bearing loads and being out of shape; When the process of making coffee is finished, when pump no longer provided aforesaid load, the deformation energy that extension spring 4 stores discharged, and housing 1 is retracted the home position.
Claims (3)
1. a coffee machine piston comprises housing and is installed on the interior piston core of housing, it is characterized in that described piston and piston core are connected in a rotating shaft of accepting the connecting rod driving force.
2. piston according to claim 1 is characterized in that being provided with reset tension spring between described rotating shaft and housing.
3. piston according to claim 2 is characterized in that described reset tension spring is symmetrical arranged.
