Description

A kind of dashing boiled head unit

Technical field

The utility model relates to a kind of dash and boils head unit, is specifically related to a kind ofly have dashing of pressure release function and boil head unit.

Background technology

Most high pressure coffee machine produces very big pressure at the Shi Douhui that makes coffee on the market at present, and expects that one glass of good to eat, high-quality this pressure of coffee is necessary conditions.Yet after boiling coffee, coffee powder can leave some pressure towards boiling internal system, do not dash the system of boiling and to form a kind of vacuum phenomenon if the pressure of this part is not discharged, just as being drawn onto, two suckers are difficult to together open, at this moment we just need a kind of relief valve, this valve has a valve that communicates with the external world, and this valve open after boiling coffee dashes the system of boiling like this and will be easy to open.Traditional pressure relief device has two kinds, a kind of is to adopt electromagnetic valve body, in this valve body string and the water route, opened by electronic program control when boiling the coffee rear electromagnetic valve, discharge internal pressure, though this valve is more stable but environment for use is had relatively high expectations, and want high a lot of with the product contrast of similar function on the cost.Mostly another is to adopt the mechanical type pressure release, and structure is complicated and because be mechanically will produce some unsettled risks, can't guarantee on quality.

The utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of dashing to boil head unit, and pressure release is effective, stable performance; Simultaneously simple in structure, it is little to take up room, with low cost.

For achieving the above object, the technical solution of the utility model is as follows: a kind of dashing boiled head unit, comprise dashing and boil a body, coffee powder box, transfer tube, back pressure apparatus and pressure relief device, the described end that boils a body that dashes is arranged in the described coffee powder box, described transfer tube is arranged on described dashing and boils in the other end of a body, and described back pressure apparatus and described pressure relief device are separately positioned on described transfer tube and described dashing boiled between the body; Described pressure relief device comprises check (non-return) valve and centring ring, and described check (non-return) valve is fixedly installed on described dashing by described centring ring and boils on the body.

Preferably, described back pressure apparatus comprises checking head and back pressure spring, and described back pressure spring connection is arranged between described checking head and the described transfer tube.

Preferably, also comprise filter screen, described filter screen is arranged on described dashing and boils on the end of a body.

Preferably, also comprise sealing ring, described sealing ring is arranged on the described junction of boiling a body and described coffee powder box that dashes.

Preferably, described check (non-return) valve is the unidirectional non-return valve body of duckbill.

Preferably, described check (non-return) valve is made by silastic material.

Adopt the beneficial effect of the technical program to be: pressure release is effective, stable performance; Simultaneously simple in structure, it is little to take up room, with low cost.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, a kind of dashing of the present utility model boiled head unit, comprise dashing and boil a body 1, coffee powder box 2, transfer tube 3, back pressure apparatus and pressure relief device, dashing an end that boils a body 1 is arranged in the coffee powder box 2, transfer tube 3 is arranged on to dash and boils in the other end of a body 1, and back pressure apparatus and pressure relief device are separately positioned on transfer tube 3 and dash and boil between the body 1; Pressure relief device comprises check (non-return) valve 4 and centring ring 5, and check (non-return) valve 4 is fixedly installed on to dash by centring ring 5 and boils on the body 1.Back pressure apparatus comprises checking head 6 and back pressure spring 7, and 7 connections of back pressure spring are arranged between checking head 6 and the transfer tube 3.Also comprise filter screen 8, filter screen 8 is arranged on to dash and boils on the end of a body 1, in the present embodiment, is fixedly connected on towards boiling on the body 1 by screw 9.Also comprise sealing ring 10, sealing ring 10 is arranged on and dashes the junction of boiling a body 1 and coffee powder box 2.

Check (non-return) valve 4 is the unidirectional non-return valve body of duckbill, and check (non-return) valve 4 need not just can reach non-return function by any external force.Check (non-return) valve 4 is made by silastic material, guarantees that check (non-return) valve 4 has elasticity.As shown in Figure 3, when pressure was discharged on the check (non-return) valve 4, check (non-return) valve 4 can begin distortion; As shown in Figure 4, meanwhile the through hole on the check (non-return) valve 4 is closed, and pressure is more big, and it is more tight that through hole is just closed.As shown in Figure 5, if pressure is from applying in the other direction, as shown in Figure 6, through hole will be opened.

As shown in Figure 7, when beginning to make coffee, the water that has pressure enters into coffee powder box 2, and pressure can apply to dashing the direction of boiling a body 1, and at first check (non-return) valve 4 cuts out through hole under the effect of pressure, make coffee to pass through, pressure begins to rise gradually, when pressure inside value during greater than the spring force of back pressure spring 7, and 7 compressions of back pressure spring, checking head 6 is backed down by pressure, and coffee flows out through transfer tube 3.After the action of making coffee is finished, this moment coffee powder box 2 with dash that to boil between the body 1 be the state that seals, be not communicated with the external world, just as two suctions sucker together, if under neither one and the extraneous this state of pipeline that can be communicated with, coffee powder box 2 boils a body 1 and can't draw back with dashing.

As shown in Figure 8, by dashing the check (non-return) valve 4 that boils in the body 1, boil a body 1 beginning when drawing back backward when dashing, through hole on the check (non-return) valve 4 can be opened, extraneous air can enter into coffee powder box 2 and dash the cavity that boils a body 1 centre by through hole, will be easy to be drawn back with coffee powder box 2 towards boiling a body 1 like this, realize the effect of pressure release.Solved the space problem when in the past adopting magnetic valve or mechanical relief valve.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
