Description

一种小体积手动咖啡机 【技术领域】
本发明涉及一种便携式的手动咖啡机。
【背景技术】
发明人研发了一款便携式的咖啡机，专利号为201310345121.5，该款咖啡机体积不大，携带比较方便，受到广大消费者的喜爱。该产品为三段式结构，其包括有可拆卸式连接在一起的杯体、水压座体和咖啡冲泡座体，由于在手动冲泡咖啡时，杯体在上面，杯体的开口朝下，安装在水压座体的上端，这样我们将水装入到水杯内时，需要把杯体的开口朝上，装入水后，水压座体倒过来先与水杯装好，此时水杯是在下端，然后再反过来让水杯在上端。这样的操作过程稍微会有点繁琐，会给使用者带来一定的不便。发明人根据这一缺陷，作出改进。
【发明内容】
本发明的目的是克服现有技术的不足，提供一种结构简单，使用方便的小体积手动咖啡机。
为了解决上述问题，本发明采用以下技术方案：
一种小体积手动咖啡机，其特征在于：包括可拆卸连接在一起的杯体和咖啡冲泡座，所述杯体的下端与咖啡冲泡座相连，所述杯体内设有水腔和压力腔，所述咖啡冲泡座内设有咖啡冲泡腔和咖啡流出通道，所述杯体内设有与压力腔连通的进水通道和连通压力腔与咖啡冲 泡腔的出水通道，所述水腔的底部设有与进水通道连通的进水孔，所述进水通道内设有能控制水从进水通道向压力腔内单向流动的进水单向控制阀，所述出水通道内设有能控制水从压力腔向咖啡冲泡腔内单向流动的出水单向控制阀，所述杯体上设有一端伸入到压力腔内的活塞杆。
如上所述的一种小体积手动咖啡机，其特征在于：所述进水孔的高度低于或者等于压力腔的高度。
如上所述的一种小体积手动咖啡机，其特征在于：所述进水通道和出水通道均位于压力腔的下方。
如上所述的一种小体积手动咖啡机，其特征在于：所述杯体与咖啡冲泡座相连的底端设有连通进水孔和进水通道的连通槽，所述连通槽下端开口，所述进水单向控制阀从连通槽下端开口安装到进水通道内，所述杯体底端设有盖住所述连通槽下端开口的安装盖。
如上所述的一种小体积手动咖啡机，其特征在于：所述进水单向控制阀包括设在进水通道内并由安装盖支撑的阀体，所述阀体内设有阀体孔，所述进水通道内设有能堵住阀体孔的进水阀芯。
如上所述一种的小体积手动咖啡机，其特征在于：所述进水通道一端设有连通压力腔的进水连通孔，所述进水阀芯为球状，所述进水连通孔位于进水阀芯上方且为方形孔。
如上所述出水通道一端设有与连通水腔的出水连通孔，所述杯体与咖啡冲泡座相连的底端设有沉槽，所述的出水通道和连通槽位于沉槽底壁上，所述的安装盖固定在沉槽内，所述安装盖上设有一端伸入 到连通槽内将连通槽和沉槽之间密封的密封头，所述安装盖上设有连通所述出水通道和咖啡冲泡腔的出水孔，所述出水单向控制阀包括由安装盖支撑的第一弹性件，所述第一弹性件上端设有能将出水连通孔封堵的出水阀芯。
如上一种的小体积手动咖啡机，其特征在于：所述的杯体的下端设有与咖啡冲泡座连接的连接开口，所述的杯体内设有将连接开口和水腔分隔的阀座，所述的压力腔、进水通道和出水通道均设在阀座上。
如上所述一种的小体积手动咖啡机，其特征在于：所述阀座与杯体一体成型。
如上所述一种的小体积手动咖啡机，其特征在于：所述阀座上端设有依次连通的泄压槽、泄压通道、泄压孔，所述泄压槽开口端连通水腔，所述泄压孔连通压力腔，所述泄压通道内设有能封堵所述泄压孔的泄压阀芯和弹压在泄压阀芯上的第二弹性件，泄压槽内设压靠在第二弹性件的泄压盖和压靠在泄压盖上将所述泄压槽开口遮盖的端盖。
如上所述一种的小体积手动咖啡机，其特征在于：杯体上端开口，所述的杯体上设有将杯体开口遮盖的杯盖。
本发明的有益效果有：
1、压力腔、进水通道、出水通道均设在杯体上，产生水压动力的部分集合在杯体上，在使用时水直接倒入到水腔内，即可使用，这样就不需要倒置的过程，且变成了两端式连接，在相同水容量的情况下，可以缩小咖啡机的体积；
2、进水通道和出水通道均位于压力腔的下方，也就是进水通道和出水通道均位于同侧，这样压力腔的上方不需要预留位置给进水通道，而进水通道和出水通道所占用压力腔下方的高度大致相当，结构紧凑，可以缩小产生压力机构占用的空间；
3、通过在杯体的底端设置连通槽，安装盖打开时，进水通道和出水通道均会外露出来，这样进水单向控制阀和出水单向控制阀可以通过连通槽进行安装，安装简单，拆洗方便；
4、阀座与杯体一体成型设计，可以大大缩小整个咖啡机的体积，结构简单，安装方便，体积小。

如图1至图9所示，一种小体积手动咖啡机，包括可拆卸连接在 一起的杯体1和咖啡冲泡座2，杯体1的下端与咖啡冲泡座2相连，所述杯体1内设有水腔11和压力腔12，杯体1上端开口，水从上端开口倒入到水腔11内，杯体1上设有将杯体1开口遮盖的杯盖14。咖啡冲泡座2内设有咖啡冲泡腔21和咖啡流出通道22，咖啡冲泡腔21内可以放入咖啡粉、咖啡粉包、胶囊咖啡等形式的咖啡，可以在咖啡冲泡腔21内放入带过滤孔的胶囊咖啡，水从上端过滤孔进入，下端过滤孔流出咖啡。杯体1内设有与压力腔12连通的进水通道3和连通压力腔12与咖啡冲泡腔21的出水通道40，水腔11的底部设有与进水通道3连通的进水孔13，进水孔13的高度低于或者等于压力腔12的高度指的是：进水孔13的最高孔面低于或者等于压力腔12腔底面的高度。进水通道3内设有能控制水从进水通道3向压力腔12内单向流动的进水单向控制阀4，出水通道40内设有能控制水从压力腔12向咖啡冲泡腔21内单向流动的出水单向控制阀5，杯体1上设有一端伸入到压力腔12内的活塞杆6，活塞杆6一端往压力腔12外拔时，压力腔12内为负压，当负压压力足够大时，控制进水单向控制阀4打开，使水从进水通道3流入到压力腔12内，当活塞杆6往压力腔12内推时，压力腔12内形成压力，压力足够大时，控制出水单向控制阀5打开，水从压力腔12流向咖啡冲泡腔21内，冲泡咖啡。
杯体1的下端设有与咖啡冲泡座2连接的连接开口15，杯体1内设有将连接开口15和水腔11分隔的阀座9，压力腔12、进水通道3和出水通道40均设在阀座9上。阀座9在水腔11内形成凸起，凸 起的一边外侧壁跟杯体1侧壁可以间隔一定距离，供水装入。压力腔12设在阀座9上中部，压力腔12在阀座9一侧开口供活塞杆6一端伸入，进水通道3和出水通道40均设在阀座9的底部。进水通道3和出水通道40均位于压力腔12的下方。
杯体1与咖啡冲泡座2相连的底端设有连通进水孔13和进水通道3的连通槽7，连通槽7下端开口，进水单向控制阀4从连通槽7下端开口安装到进水通道3内，杯体1底端设有盖住连通槽7下端开口的安装盖8，安装盖8可以通过螺钉等连接件固定在杯体1底端。进水单向控制阀4包括设在进水通道3内并由安装盖8支撑的阀体41，阀体41内设有阀体孔42，进水通道3内设有能堵住阀体孔42的进水阀芯43。进水通道3一端设有压力腔12的进水连通孔31，进水阀芯43为球状，进水连通孔31位于进水阀芯43上方且为方形孔，这样球状的进水阀芯43即使被向上吸入到进水连通孔31内时，由于进水连通孔31为方形，球状进水阀芯43仍然无法堵死进水连通孔31，而阀体孔42为圆形，球状进水阀芯43向下时可以堵住阀体孔42。出水通道40一端设有与连通水腔11的出水连通孔44，杯体1与咖啡冲泡座2相连的底端设有沉槽45，出水通道40和连通槽7位于沉槽45底壁上，安装盖8通过螺钉固定在沉槽45内，安装盖8上设有一端伸入到连通槽7内将连通槽7和沉槽45之间密封的密封头80，密封头80堵入连通槽7内，但是连通进水孔13和进水通道3保持连通，可以在密封头80外套密封圈，这样连通槽7和沉槽45之间不连通，安装盖8上设有连通出水通道40和咖啡冲泡腔21的出水孔 71。出水单向控制阀5包括由安装盖8支撑的第一弹性件81，安装盖8上设有十字形凸块，第一弹性件81套在十字形凸块顶部，出水孔71在十字形凸块上，第一弹性件81上端设有能将出水连通孔44封堵的出水阀芯82，出水单向控制阀5包括由安装盖8支撑的第一弹性件81，第一弹性件81上端设有能将出水连通孔44封堵的出水阀芯82，第一弹性件81向上弹压出水阀芯82，使出水阀芯82堵在出水连通孔44上，当压力腔12压力足够大时，使第一弹性件81收缩，出水连通孔44打开。当取下安装盖8，进水单向控制阀4和出水单向控制阀5均能被取出来或者安装上去，方便拆洗和安装。同时，由于连通槽7设计在杯体1的底端，进水单向控制阀4和出水单向控制阀5均可以从底端实现安装，这样也方便实现阀座与杯体一体成型设计，简化成型工艺。
阀座9上端设有依次连通的泄压槽91、泄压通道92、泄压孔93，泄压槽91开口端连通水腔11，泄压孔93连通压力腔12，泄压通道92内设有能封堵所述泄压孔93的泄压阀芯94和弹压在泄压阀芯94上的第二弹性件95，泄压槽91内设压靠在第二弹性件95的泄压盖96和压靠在泄压盖96上将所述泄压槽91开口遮盖的端盖97，泄压盖96通过螺钉固定，泄压盖96和泄压槽91方便泄压阀芯94安装。第二弹性件95弹性力成倍的大于第一弹性件81的弹性力，当压力腔12内压力太大存在安全隐患时，会顶开泄压阀芯94而进行泄压。
