Description

一种磨豆器
本申请要求于2019年07月31日提交中国专利局、申请号为201910701535.4、发明名称为“一种磨豆器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及家用电器技术领域，特别涉及一种磨豆器。
背景技术
现有的磨豆器，例如全自动咖啡机或咖啡磨豆器，主要包括上下设置的咖啡豆盒和磨豆组件，咖啡豆盒内的咖啡豆在重力的作用下自由落至磨豆组件中进行研磨，待磨成咖啡粉之后就会落入冲泡***内，进行冲泡咖啡之用。
目前的咖啡磨豆器主要是一个豆盒对应一个独立的磨豆组件，当用户选择不同的咖啡豆进行研磨时，磨豆器内会存留咖啡粉，进而影响下次咖啡豆的研磨。为了不使用户选用的咖啡豆味道被上一次研磨的咖啡豆所影响，若使用至少两组独立的咖啡豆研磨组件来解决上述问题，会增加磨豆器体积，成本也会增高。
因此，如何提供一种结构简单、成本较低的磨豆器，是本领域技术人员目前需要解决的技术问题。
发明内容
有鉴于此，本发明的目的是提供一种磨豆器，能够在一个磨豆刀组件的前提下，实现对不同豆的研磨。
为实现上述目的，本发明提供如下技术方案：
一种磨豆器，包括：磨豆刀组件和多个豆仓，所述磨豆刀组件设置在所述豆仓的底部，各所述豆仓的底部均设有送豆螺杆，所述送豆螺杆用于将与其对应的所述豆仓内的豆输送至所述磨豆刀组件。
优选地，包括左豆仓和右豆仓，所述左豆仓和所述右豆仓底部的所述 送豆螺杆为同一根长螺杆，当所述长螺杆正转时，仅所述右豆仓内的豆被输送至所述磨豆刀组件内；当所述长螺杆反转时，仅所述左豆仓内的豆被输送至所述磨豆刀组件内。
优选地，还包括用于驱动所述长螺杆转动的送豆马达。
优选地，所述左豆仓和所述右豆仓的底部设有圆筒送料通道，所述长螺杆穿过所述圆筒送料通道内部，所述圆筒送料通道的上部左右两侧各设有一个进料口，所述圆筒送料通道的底部设有出料口。
优选地，所述送豆螺杆的两端水平铰接在所述豆仓的侧壁上。
优选地，还包括检测装置和控制装置，所述检测装置用于检测所述送豆螺杆的转数，所述控制装置用于根据所述检测装置检测到的转数符合预设需求时，控制所述送豆马达停转。
优选地，所述豆仓的底部可拆卸连接在所述磨豆刀组件的进豆口处。
与现有技术相比，上述技术方案具有以下优点：
本发明所提供的一种磨豆器，包括：磨豆刀组件和多个豆仓，磨豆刀组件设置在豆仓的底部，各豆仓的底部均设有送豆螺杆，当需要研磨某个豆仓内的咖啡豆时，转动与其相对应的送豆螺杆即可输送至磨豆刀组件中，当需要一定配比的咖啡粉时，可通过转动送豆螺杆的转数来确定送料量，送豆结束之后，磨豆刀组件应再工作一段时间，以确保磨豆刀组件内的咖啡豆被完全磨完及清空，以便于下一次的磨豆作业。通过本申请提供的磨豆器，通过不同的豆仓和送豆螺杆的组合，不仅可对不同的咖啡豆进行输送研磨，还可实现不同配比咖啡豆的研磨作业，此外还具备结构简单，产品生产成本低的优势。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

图2为本发明一种具体实施方式所提供的一种磨豆器的局部***结构示意图；
图3为本发明一种具体实施方式所提供的一种磨豆器的主视结构示意图；
图4为本发明一种具体实施方式所提供的一种磨豆器的主视剖视结构示意图。
附图标记如下：
1为磨豆刀组件，2为豆仓，21为左豆仓，22为右豆仓，23为圆筒送料通道，231为进料口，232为出料口，3为长螺杆，4为送豆马达。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图1～图4，图1为本发明一种具体实施方式所提供的一种磨豆器的立体结构示意图；图2为本发明一种具体实施方式所提供的一种磨豆器的局部***结构示意图；图3为本发明一种具体实施方式所提供的一种磨豆器的主视结构示意图；图4为本发明一种具体实施方式所提供的一种磨豆器的主视剖视结构示意图。
本发明实施例所提供的一种磨豆器，可用于咖啡豆或其它豆类的研磨作业，本实施例以研磨对象为咖啡豆进行距离说明，磨豆器包括：磨豆刀组件1和多个豆仓2，豆仓2的数量可根据需求进行选择，磨豆刀组件1设置在豆仓2的底部，各豆仓2的底部均设有送豆螺杆，送豆螺杆在转动 之前，豆仓2内放置一定量的咖啡豆，当需要研磨某个豆仓2内的咖啡豆时，转动与其相对应的送豆螺杆即可输送至磨豆刀组件1中，当需要一定配比的咖啡粉时，可通过转动送豆螺杆的转数来确定送料量，送豆结束之后，即送豆螺杆停止转动时，磨豆刀组件1应再工作一段时间，以确保磨豆刀组件1内的咖啡豆被完全磨完及清空，以便于下一次的磨豆作业。通过本申请提供的磨豆器，通过不同的豆仓2和送豆螺杆的组合，不仅可对不同的咖啡豆进行输送研磨，还可实现不同配比咖啡豆的研磨作业，此外还具备结构简单，产品生产成本低的优势。
需要说明的是，磨豆刀组件1的具体结构和工作原理可参考现有技术，此处不再赘述。
优选包括两个豆仓2，例如设置在磨豆刀组件1上部的左豆仓21和右豆仓22，左豆仓21和右豆仓22底部的送豆螺杆为同一根长螺杆3，由于螺杆的结构特性，其具备单向输送的特点，即当朝一个方向转动，物料会朝着螺旋叶推进的方向输送，所以当长螺杆3正转时，仅右豆仓22内的咖啡豆被输送至磨豆刀组件1内；当长螺杆3反转时，仅左豆仓21内的咖啡豆被输送至磨豆刀组件1内，可以理解的是，当输送其中一个豆仓2内的咖啡豆时，另一个豆仓2内的咖啡豆不会掉落，只有在长螺杆3反转的情况下，另一个豆仓2内的咖啡豆才会掉落。
进一步地，还包括与长螺杆3的一端连接的送豆马达4，送豆马达4用于驱动长螺杆3转动，通过送豆螺杆正反转可控制豆的配比，例如用户选择的A豆和B豆的比例是1：3，那么送豆马达4的正转和反转时间比例就以1：3来进行运行，正反转的方式可以是先正转再后反转，或者先反转再正转，或者正反转交替进行均可，只要总正反转时间比为1:3即可。送豆螺杆水平设置在豆仓2的底部，即送豆螺杆的两端转动连接在豆仓2的侧壁上，为了便于更换豆仓2，可将豆仓2可拆卸连接在磨豆刀组件1的送豆口处，其中优选将送豆螺杆和豆仓2作为一个整体组件可拆卸连接在磨豆刀组件1的送豆口处。
具体地，左豆仓21和右豆仓22的底部设有圆筒送料通道23，长螺杆3穿过圆筒送料通道23内部，其中可使长螺杆3的螺旋叶片外侧边缘与圆 筒送料通道23的内侧壁相互接触，以防止咖啡豆自由落入磨豆刀组件1内，圆筒送料通道23的上部左右两侧各设有一个进料口231，圆筒送料通道23的底部设有出料口232。
进一步地，还包括检测装置和控制装置，其中检测装置可使用霍尔感应器，检测装置用于检测送豆螺杆的转数，控制装置分别与检测装置和送豆马达4连接，控制装置用于根据检测装置检测到的转数符合预设需求时，控制送豆马达4停转，即通过控制送豆马达4的转数，可精确控制咖啡粉的使用量而不受用户调节磨豆刀粗幼度的影响，因传统控制咖啡粉量的方式是通过磨豆马达的工作时间来控制的，但是磨豆刀粗幼度是供用户可调校时，则咖啡粉的量就会变得不准确，因为在设定为粗粉时，上下磨豆刀的间隙会变大，咖啡粉同一时间的输出量就会变大，但通过送豆螺杆送豆之后，豆量就会由螺杆的转数决定而不是受磨豆刀组件1的影响。
值得一提的是，本申请可使用一根螺杆正反转及一个送豆马达便能控制两个豆仓做独立送豆之用，当然，在本领域的技术人员可想到改为分开两条独立螺杆及两个送豆马达也能实现两个豆仓的独立送豆作业，也在本发明的保护范围之内，本领域技术人员在图一所示的技术方案，也可联想到增加一组咖啡豆仓及咖啡豆传送装置，就可以实现一个磨刀组件配合四个豆仓，即用户可作四种不同咖啡味道选择，对于6种、8种咖啡味道选择的方案也可如此类推，另外若要实现3中咖啡味道的方案，在图一的基础上，增加一个豆仓和独立螺杆以及送豆马达即可。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
以上对本发明所提供的一种磨豆器进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
