Description

A kind of extraction handle of pressure-adjustable

Technical field

The utility model relates to coffee machine technical field, the extraction handle of especially a kind of pressure-adjustable.

Background technique

In the brewing process of coffee, extraction is that wherein extremely the key link, extraction can guarantee the substance in ground coffee It is sufficiently dissolved into water, can effectively promote infused coffee mouthfeel.In the prior art, the extraction on coffee machine requires to make Extraction handle is used, extraction handle includes extracting head and gripping handle, and extracting head has the extraction docked with the brew head of coffee machine Take chamber.When extracting head is docked with brew head, extraction chamber is in relatively closed state, since the discharge pressure of brew head is fixed, The volume of extraction chamber is fixed so that extracting pressure extract it is intracavitary be also kept fixed, can not be adjusted, and in fact, different Coffee need different extracting pressures, can be only achieved and optimal brew effect.Therefore, it is necessary to provide a kind of adjustable pressure Extraction handle.

Utility model content

The utility model provides a kind of extraction handle of pressure-adjustable, can regulate and control extracting pressure, to be suitable for different coffees Brew.

A kind of extraction handle of pressure-adjustable, including extracting head and gripping handle, the extracting head are equipped with extraction tank, extraction The bottom connecting tube with outward extension of head, the connecting tube are equipped with the flowing hole being connected to extraction tank；In the connecting tube It is socketed with casing, the lower end of casing is equipped with the outlet flowed out for coffee liquid；Spring and gasket, the bullet are equipped in described sleeve pipe The lower end of spring is fixed in sleeve, and the upper end of spring is arranged in gasket；Under the resilient force of spring, the gasket is supported It connects in the lower end of connecting tube to block the flowing hole；Regulating mechanism is additionally provided in described sleeve pipe, described sleeve pipe is for passing through institute It states regulating mechanism and changes it to the spacing between extracting head.

Preferably, the regulating mechanism is the internal screw thread being arranged in casing, the outer wall of the connecting tube be equipped with it is described The external screw thread that internal screw thread matches.

Preferably, the radius of the gasket is greater than the radius of spin of spring, and the lower end of the gasket, which is equipped with, to be inserted into Inserted link in spring axis hole.

Preferably, the inner wall of described sleeve pipe lower end is equipped with snap ring, and the outlet is the central through hole of the snap ring, the bullet The lower end of spring is fixed on the snap ring.

Preferably, the lower end of described sleeve pipe is equipped with product mouth, and the product mouth is docked with the outlet.

In the utility model, gasket blocks flowing hole under the resilient force of spring, when the extraction pressure in extraction tank Power is greater than scheduled pressure, and the coffee liquid by extraction can overcome the elastic force of spring, open gasket, thus from outlet stream Out.Meanwhile sleeve can be mobile relative to connecting tube, and then changes the elastic force of spring, can also set in extraction tank most Big extracting pressure, to be suitable for brewing for variety classes coffee.

Fig. 2 is a kind of cross-sectional view of the extraction handle of pressure-adjustable of embodiment of the utility model.

Specific embodiment

The utility model is described in further detail below by specific embodiment combination attached drawing.

The utility model embodiment provides a kind of extraction handle of pressure-adjustable, as depicted in figs. 1 and 2 comprising extracting head 1 With gripping handle 11, gripping handle 11 is used to hold for user.The extracting head 1 is in similar spoon shape structure, the top of extracting head 1 Equipped with extraction tank 10, the extraction of coffee liquid is carried out in extraction tank 10.It is only partial cross structure in Fig. 2, extracting head 1 needs It to be docked with the brew head on coffee machine, extraction tank 10 is in relatively closed environment, and brew head is discharged the extraction to be extracted In the process, the pressure in extraction tank 10 can increase, and the present embodiment will make its internal pressure controllable.

In the bottom of extracting head 1 connecting tube 2 with outward extension, the connecting tube 2 is equipped with to be connected to extraction tank 10 Flowing hole 20, coffee liquid extracted can be flowed out from the flowing hole 20.Casing 3, casing 3 are socketed in the connecting tube 2 Internal diameter be slightly larger than the outer diameter of connecting tube 2, and there is regulating mechanism on casing 3, by the regulating mechanism, casing 3 can be even It is slided on adapter tube 2, arrives the distance between extracting head 1 to change casing 3.It is equipped with to go out for what coffee liquid flowed out in the lower end of casing 3 Mouthful, coffee liquid flows out after the outflow of flowing hole 20, then from the outlet.

Spring 43 and gasket 41 are equipped in described sleeve pipe 3, gasket 41 can be discoid rubber disc, radius Greater than the radius of flowing hole 20.The lower end of the spring 43 is fixed in sleeve 3, and the upper of spring 43 is then arranged in gasket 41 End.By default, spring 43 is compressed, so that spring 43 provides elastic force, since 43 lower end of spring is fixed, then spring 43 Upper end will jack up gasket 41, so that gasket 41 is tightly connected to the lower end of connecting tube 2, so as to block the flowing hole 20。

Since the elastic force that spring 43 provides is related by compression distance to it, the adjustable casing 3 of those skilled in the art To the distance of extracting head 1, to control the elastic force of the generation of spring 43.As long as the extracting pressure in extraction tank 10 is produced greater than spring 43 Raw elastic force, can open gasket 41.Therefore, those skilled in the art can be a variety of for " Kapp Cino Da Pistoia ", " latte " etc. The coffee of type, adjusting sleeve pipe 3 to appropriate location, limits the maximum extraction pressure that can achieve in extraction tank 10 respectively, once Extracting pressure is greater than the elastic force that spring 43 generates, and coffee liquid extracted flows out automatically.

In one embodiment, the regulating mechanism is the internal screw thread being arranged in casing 3, the outer wall of the connecting tube 2 Equipped with external screw thread matched with the internal thread.Casing 3 can be mobile relative to connecting tube 2 by rotation, is arrived with adjusting sleeve pipe 3 The distance of extracting head 1.Meanwhile the cooperation between screw thread has good leakproofness, and coffee liquid can be prevented from casing 3 and connection Gap between pipe 2 sprays.

In one embodiment, the radius of the gasket 41 is greater than the radius of spin of spring 43, and the upper end of spring 43 is supported It connects in the lower surface of gasket 41, meanwhile, the lower end of the gasket 41 is equipped with the inserted link 42 being inserted into the axis hole of spring 43, That is the periphery that will be centered around inserted link 42 of spring 43, plays effective position-limiting action, prevents gasket 41 from applying elasticity in spring 43 Lateral displacement is generated when power.

In one embodiment, the inner wall of 3 lower end of described sleeve pipe is equipped with snap ring 31, has central through hole in the middle part of snap ring 31, The through-hole is the outlet of casing 3.The outer diameter of its snap ring 31 is greater than the radius of spin of spring 43, then the lower end of the spring 43 is solid It is scheduled on the snap ring 31.

Further, the lower end of described sleeve pipe 3 is equipped with product mouth 5, and the product mouth 5 is docked with the outlet, product mouth 5 With corresponding flowing water mouth, the radius of flowing water mouth can be gradually reduced along the flow direction of coffee liquid, the coffee liquid gone out to prevent fluid stopping Splashes.

The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field For, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made.
