Position is installed with thimble, and spring is supported by between thimble and fixing seat, and fixing seat side is provided with and flows what chamber was connected in stroke block
Aperture, stroke block lower end surface are provided with filter screen.
But brewing device of coffee maker described above, its structure is complicated, and manufacturing cost is higher, and brewing pressure fixation causes
Single effect is brewed, the cavity gap of fixing seat is excessive, causes operating noise larger.
Utility model content
The purpose of the utility model is to provide a kind of brewing pressure control device of coffee, with brewing pressure it is adjustable with
The effect of noise is reduced, and structure is more simple, production is more convenient, reduces manufacturing cost.
What the above-mentioned technical purpose of the utility model had the technical scheme that a kind of coffee brews pressure
Force control device, including fixing sleeve and adjustment cap, the lower end of fixing sleeve offer inlet opening, and the inside of fixing sleeve, which offers, to be used for
The cavity brewed, the interior limit of the cavity are installed with chock plug, and one end of the adjustment cap, which is inserted into cavity, to be connected through a screw thread
It is fixed on the upper end of fixing sleeve, the upper end of the adjustment cap is supported between the adjustment cap and chock plug and set through apopore is offered
There is pagoda-shaped spring.
Further, the chock plug has been arranged concentrically guide post far from one end of water inlet.
Further, the longitudinal section of the inlet opening is " work " type structure.
Further, the inlet opening close to one end of cavity longitudinal section be it is trapezoidal, the chock plug is close to inlet opening
One end is the chondritic with inlet opening cooperation sealing.
Further, the flat portion that the side wall of the fixing sleeve offers convenient for holding.
Further, the eight-sided formation that the adjustment cap is equipped with convenient for knob far from one end of fixing sleeve.
In conclusion the utility model has the following beneficial effects: a kind of brewing device of coffee maker, in chock plug and adjustment cap
Between support set pagoda-shaped spring, change the decrement of pagoda-shaped spring by knob adjustment cap, to adjust brewing pressure model
It encloses；The cavity for being used to brew is less than the stream chamber of the prior art, reduces operating noise；The brewing device of coffee maker structure letter
Single, module independent is convenient for production to which cost reduces.
Detailed description of the invention
Fig. 1 is the whole explosive view of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
In figure: 1, fixing sleeve；11, inlet opening；12, flat portion；2, chock plug；21, guide post；3, pagoda-shaped spring；4, it adjusts
Cap；41, apopore.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, a kind of brewing pressure control device of coffee, including fixing sleeve 1 and adjustment cap 4, under fixing sleeve 1
End offers inlet opening 11, and the inside of fixing sleeve 1 offers the cavity for brewing, and limit is installed with chock plug 2 in the cavity,
The upper perimeter wall of cavity is equipped with internal screw thread, and one end of the adjustment cap 4 is inserted into cavity to be connected through a screw thread and be fixedly installed in
Surely the upper end of set 1, the upper end of the adjustment cap 4 are supported between the adjustment cap 4 and chock plug 2 and are equipped with through apopore 41 is offered
Pagoda-shaped spring 3.
As shown in Fig. 2, the chock plug 2 has been arranged concentrically guide post 21 far from one end of water inlet, pagoda-shaped spring 3 it is outer
The lesser one end of diameter is sheathed in guide post 21, and the other end of pagoda-shaped spring 3 is closely against adjustment cap 4, by the way that guide post is arranged
21, when jacking up chock plug 2 by high-pressure water heating will not pagoda-shaped spring 3 be detached from, cause not resetting after the completion of brewing, and then can not
To inlet seal.
The longitudinal section of the inlet opening 11 is that less coffee blocks " work " type structure, and " work " the type structure is offered and led
To annulus, high-pressure water heating enters inlet opening 11 by being oriented to annulus, and high-pressure water heating overcomes the elastic force of pagoda-shaped spring 3 to jack up chock plug
2 are brewed, and high-pressure water heating flows into the channel narrows of inlet opening 11, the flow velocity of high-pressure water heating increases, and are avoided and are not melted
Ground coffee blocks inlet opening 11.
The longitudinal section of the one end of the inlet opening 11 close to cavity is trapezoidal, the one end of the chock plug 2 close to inlet opening 11
For the chondritic with the cooperation sealing of inlet opening 11, after coffee brew and finished, bullet of the chock plug 2 in pagoda-shaped spring 3
Guiding annulus under the action of power again with inlet opening 11 is sealed tight against cooperation.
The flat portion 12 that the side wall of the fixing sleeve 1 offers convenient for holding, adjustment cap 4 are equipped with far from one end of fixing sleeve 1
Convenient for the eight-sided formation of knob, when brewing pressure to be changed, as long as holding the flat portion 12 of fixing sleeve 1, proficiency knob on the other hand
Adjustment cap 4 changes the relative position of adjustment cap 4 and fixing sleeve 1 to change pagoda-shaped spring 3 to the pressure set on chock plug 2, in turn
Coffee changes the pressure brewed, achievees the effect that well to brew.
The basic functional principle of the utility model are as follows:
When hot water is after the container for filling ground coffee, by the pressurization of water pump so that the upward play of hot water, hot water pass through
Filter screen pours in the inlet opening 11 of fixing sleeve 1, and pressurized hot water persistently pours in water inlet, until overcoming pagoda-shaped spring 3
Elastic force jacks up chock plug 2 and is brewed into cavity, and finally from outflow apopore 41, after coffee brewing finishes, chock plug 2 is in treasured
The elastic force effect of tower spring 3 is lower to be resetted；When the brewing pressure of coffee to be changed, as long as holding the flat portion of fixing sleeve 1 on the other hand
12, proficiency knob adjustment cap 4 changes the relative position of adjustment cap 4 and fixing sleeve 1 and supports to change pagoda-shaped spring 3 set on chock plug 2
Pressure, and then coffee changes the pressure that brews, achievees the effect that well to brew.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
