Abstract
The utility model discloses a kind of tops of coffee-making machine brewing unit, it includes fixed part (1) and movable part (2), upper filter screen (3) are fixed on movable part (2), fixed part (1) and movable part (2) mutually fitting and being equipped between fixed part (1) and movable part (2) both prevents the limiting device being detached from, equipped with pressure spring (4) between fixed part (1) and movable part (2)；The top further includes the device for limiting movable part (2) climb.The top, which is added or added regardless of ground coffee amount, can ensure ground coffee to be pressurized when brewing less that constant, compaction is consistent.
Description
Technical field
The utility model relates to a kind of components of coffee machine, specifically a kind of top of coffee-making machine brewing unit.
Background technique
The brewing unit of coffee machine is the core component that coffee machine is used to infuse coffee, and also referred to as makes core in industry,
It generally comprises the top being fixed on coffee machine support, rack-mount elevating mechanism and the wine connecting with elevating mechanism
Device is made, opening up brewing cavity is equipped in maker, is equipped with lower filter plate in brewing cavity；Top bottom is fixed with upper filter screen, pushes up
Head in be equipped with liquid outlet pipe, and in maker, the lower section of lower filter plate be equipped with water inlet pipe.
The working principle of prior art brewing unit is, when initial position connects powder station, brewing cavity is located at top lower section
And the two, there are more greatly powder interval, the milling device of coffee machine gets rid of ground ground coffee into wine through the upper opening of brewing cavity
It makes chamber, fall in above lower filter plate, that is, complete to connect powder step；Then elevating mechanism driving maker rises so that brewing cavity upper opening
It is inserted in top and realizes brewing cavity closing, be further continued for rising so that ground coffee is compacted on the upper filter screen of top by lower filter plate, then
Hot water enters brewing cavity from water inlet pipe and infuses coffee powder, and the coffee brewed is discharged by liquid outlet pipe again.
The brewing unit of the prior art have the following deficiencies: due to top position be it is fixed, to ensure to seal, thus rise
The climb of descending mechanism i.e. the upper limit position of maker are also to set, and thus cause a quagmire, i.e., often
Secondary plus powder amount is difficult to hold, if ground coffee is few, it is likely that brew the ground coffee on filter plate at present with the upper filter screen root of top
Originally without contact to can not be compacted, and if ground coffee is more, upper filter screen and lower filter plate are by ground coffee to both up and down
To pressure it is excessive, can so damage and failure be caused to top and maker for a long time, or even due to the excessive maker of ground coffee
The brewing station of setting can not be risen at all and cause maker that can not be closed；Stated differently, since each plus powder amount without
Method is consistent, and compaction when ground coffee brews also is difficult to unified, and certainly will also influence whether coffee in this way brews mouthfeel and matter
Amount.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of regardless of ground coffee amount is added or plus less can be true
Ground coffee is protected to be pressurized when brewing the top of the constant consistent coffee-making machine brewing unit of compaction.
The technical solution of the utility model is to provide a kind of top of coffee-making machine brewing unit, it includes fixed part
And movable part, upper filter screen, fixed part and the mutual fitting of movable part are fixed on movable part and are equipped between fixed part and movable part
The limiting device for preventing the two to be detached from is equipped with pressure spring between fixed part and movable part；The top further includes for limiting movable part
The device of climb.
The work process for being equipped with the brewing unit of above-mentioned top is that maker is risen after connecing powder by lifting device driving,
On the ground coffee on the lower filter plate of maker abuts against the upper filter screen of the movable part bottom surface of top, and hereafter maker continues
Liter, lower filter plate will push the movable part of top is synchronous to rise through ground coffee, movable part uphill process meeting synchronous compression pressure spring, and
Due to limiting the effect of device, the distance that movable part rises be it is fixed, the final upper limit position of movable part be also it is fixed, this
Sample, finally, regardless of ground coffee add or plus it is few, the above-mentioned distance of movable part i.e. pressure spring are also constant by decrement
, therefore the pressure that coffee is subject to finally is also constant.
To sum up, the top of coffee-making machine brewing unit using the above structure compared with prior art, has the advantage that
As soon as above structure substantially realizes a function, coffee can be ensured less by adding or adding regardless of ground coffee amount
Powder is pressurized when brewing, and constant, ground coffee compaction is consistent, in this way, both ensure that the stabilization and quality of coffee brewing mouthfeel,
It in turn avoids can not being compacted or press in the prior art obtaining the predicament that can not be closed of tension even maker, extends making for structure
Use the service life.
As an improvement, movable part is fixed with the head end connector of liquid outlet pipe, the end that fixed part is fixed with liquid outlet pipe is connect
Head, two connectors are connected through flexible transition pipeline section；Thus it is ensured that liquid outlet pipe is whole when movable part and fixed part relative motion
No leakage, smooth work.
The limiting device for preventing movable part and fixed part to be detached from is preferred are as follows: movable part includes outer tube side wall and bottom plate, is fixed
Portion includes inner cylinder side wall and partition, and movable part is linked in outside fixed part；Guide post, fixed part partition are fixed on movable part bottom plate
It is passed through equipped with pilot hole, at the top of guide post at the top of pilot hole and guide post and is combined with screw, the washer diameter below screw head
Greater than pilot hole aperture；Pressure spring be linked in guide post and pressure spring both ends respectively with movable part bottom plate and fixed part partition against.
Above-mentioned limiting device realizes the limit to movable part first, prevents movable part from falling off under the effect of gravity, moreover, pilot hole
The design of guide post further improve guiding performance so that the relatively fixed portion's lifting of movable part is more reliable and more stable；On moreover
It is very convenient to state Standard, assembly can be rapidly completed in screw-in screw after guide post is inserted into pilot hole；Even, the guide post
Presence, solve the installation question of pressure spring, so that pressure spring installation site rationally consolidates, it is ensured that pressure spring can continue working, reduce
Failure rate；To sum up, above structure perfection incorporates guiding, limit Anti-fall and the function of installing pressure spring.
The device for limiting movable part climb is preferred are as follows: is fixed on the outer tube side wall of movable part and opens for triggering stroke
The briquetting of pass, and travel switch is just mounted on the fixation position of coffee machine support, in this way, movable part rises to fixed height every time
Will pressing stroke switch, formed electric signal, go cutting lifting device circuit, it is ensured that movable part upper limit position it is accurate, and
Braking effect is sensitive after ensure that movable part arrival upper limit position.
The device for limiting movable part climb is another preferably are as follows: the outer tube side wall convex of movable part have a circle for it is solid
Determine the inner cylinder side wall lower edge in portion against annular stop step；In this way, movable part rises to some fixed height every time, activity
The annular stop step in portion will be with fixed part inner cylinder side wall lower edge even at the cost of one's life；Above method structure is simple, and function-stable is reliable,
It is accurate to movable part limit.
