技术领域
本发明涉及厨房用具领域，具体而言，涉及一种挤压螺杆、挤压组件及食物料理机。
背景技术
目前市面上的原汁机挤汁及排渣都是靠螺旋头及榨汁杯底部装的胶塞完成，但由于排渣的受力方向与螺旋头转动的推力方向不一致，因而导致挤汁力度及排渣力度不够，从而经常会有排渣口堵塞及渣不干的现象。
因此，如何提出一种挤汁与排渣的受力方向与杆体的推力方向一致，以避免出现渣不干及排渣口易堵的现象成为目前亟待解决的问题。
发明内容
本发明旨在至少解决现有技术或相关技术中存在的技术问题之一。
因此，本发明的一个目的在于提供了一种挤压螺杆。
本发明的另一个目的在于提供了一种挤压组件。
本发明的再一个目的在于提供了一种食物料理机。

根据本发明第一方面的实施例提供的挤压螺杆，挤压螺杆的杆体包括依次 连接的进料段和挤压段和排渣段，排渣的受力方向沿着杆体的轴向方向，且杆体的推力方向也沿着杆体的轴向方向，从而使得挤压螺杆的挤汁与排渣的受力方向与杆体的推力方向一致，从而可增大挤汁力和排渣力，使得排渣口处的食物渣更易被排出，进而即可减少食物渣堵塞排渣口的现象，同时，由于挤汁力增大，因而会有更多的食物汁被挤压出来，因而一方面可提高食物的出汁率，另一方面由于食物渣中含有的食物汁更少，从而能够使得食物渣更干，进而可避免出现食物渣不干的现象。同时，杆体的横截面的面积从进料段至挤压段逐渐增大，即杆体从进料端至挤压段逐渐变粗，该种设置在将挤压螺杆安装在食物料理机的第一桶体内时，挤压螺杆与第一桶体的内壁配合，以形成挤压通道以对食物进行夹击挤压，而杆体从进料端至挤压段逐渐变粗，从而使得挤压螺杆与第一桶体的内壁形成的挤压通道能够逐渐变窄，进而能够增大挤压螺杆与第一桶体的内侧壁作用于食物上的挤压力度，以提高出汁率。
在上述技术方案中，优选地，所述挤压螺杆还包括：安装轴，所述杆体套设在所述安装轴上，用于安装所述杆体。
在该技术方案中，可利用安装轴来实现挤压螺杆与电机等驱动组件之间的驱动连接，从而挤压螺杆便能够在电机等驱动组件的驱动下转动以使食物的汁渣分离。

在该技术方案中，挤压螺杆的横截面的面积从靠近挤压段的一端向远离挤压段的一端逐渐减小，即是说挤压螺杆的杆体在出渣段时逐渐内收，该种设置挤压螺杆的杆体在出渣段时逐渐内收，从而使得杆体的出渣段与第一桶体的内侧壁之间的间隙增大，进而能够减小挤压螺杆和第一桶体对食物渣的阻力，以使食物能够顺利排出，进而即可防止出现食物渣堵塞排渣口的现象。
在上述技术方案中，优选地，所述杆体的所述进料段和所述挤压段上设置有螺纹，所述螺纹的螺距从所述进料段至所述挤压段逐渐减小。
在该技术方案中，螺纹能够在杆体上形成螺旋槽，从而能够利用该螺旋槽引导食物从进料段依次向挤压段、排渣段推进，并从排渣段排出。同时，螺纹的螺距从进料段至挤牙段逐渐减小，即挤压螺杆的容积率逐渐减小，因而挤压螺杆对食物的压缩率逐渐增大，因而该种设置也能够提高挤压螺杆的挤汁力度，以提高出汁率。
在上述技术方案中，优选地，所述挤压螺杆的压缩比为A，所述压缩比A的值为：1.8≤A≤3.6，进一步优选地，所述压缩比A在2.5至3的范围内，其中，螺杆的压缩比指的是进料段上的第一个螺距的容积与挤压段最后一个螺距的容积之比，而挤压螺杆的螺距指的是相邻两个螺纹之间沿杆体轴向方向的距离，螺距的容积指的是该段距离中上可容纳的食物量。
在上述技术方案中，优选地，所述杆体的所述进料段上设置有多个压料平面。
在该技术方案中，可将挤压螺杆的进料段上的第一个螺纹和第二个螺纹之间的杆段切成平面，以形成所述压料平面，从而更利于该压料平面将粉碎后的食物引导至挤压螺杆所在的第一桶体内。
在上述技术方案中，优选地，所述进料段上设置有挡料板，所述螺纹从所述挡料板处向所述挤压段延伸，所述挡料板靠近所述螺纹的面上具有导向斜面。
在该技术方案中，可在进料段上设置一个挡料板，并利用该挡料板与第一个螺纹形成一个容料腔，从而粉碎后的食物能够直接落入到该容料腔内，而将挡料板靠近螺纹的一面上设置导向斜面，能够减少挡料板对粉碎后的食物的阻力，以利于粉碎后的食物进入到容料腔内。
在上述技术方案中，优选地，所述螺纹与所述杆体连接的一端的宽度为D1，所述D1的值为：5mm≤D1≤12.99mm。
在该技术方案中，通过将螺纹与杆体连接的一端(即螺纹的根部)的宽度设置在大于等于5mm小于等于12.99mm的范围内，使得螺纹与杆体具有一定的连接宽度，因而能够提高螺纹与杆体之间的连接强度，从而即可防止挤压螺杆的螺纹在挤汁排渣过程中断裂的情况发生，进而能够提高挤压螺杆的整体强度，延长挤压螺杆的使用寿命。
在上述技术方案中，优选地，所述螺纹远离所述杆体的一端的宽度为D2，所述D2的值为：1mm≤D2≤4.99mm。
在该技术方案中，通过将螺纹远离杆体的一端(即螺纹的端部)的宽度设置在大于等于1mm小于等于4.99mm的范围内，使得螺纹的端部宽度较小，因而能够更快速地引导粉碎后的食物沿着挤压螺杆依次从进料段向挤压段及排渣段移动，进而提高能够挤压螺杆的挤汁排渣效率。
在上述技术方案中，优选地，所述螺纹在所述杆体的径向上的投影高度为H，所述投影高度H的值为：0.5mm≤H≤13.99mm。
在该技术方案中，通过将螺纹在杆体的径向上的投影高度设置在大于等于0.5mm小于等于13.99mm的范围内一方面使得螺纹具有一定的高度，因而便能够与杆体围成具有一定容积的螺旋槽，而粉碎后的食物从进料段进入到该螺旋槽内，并沿着螺旋槽逐渐向排渣段移动，进而即可完成挤汁排渣，同时将螺纹在杆体的径向上的投影高度设置在大于等于0.5mm小于等于13.99mm的范围内，不会使得螺纹的高度过高，因而能够确保螺纹的整体强度，进而便能够适当地提高挤压杆对食物的挤压程度，以提高食物的出汁率，同时，螺纹的强度提高后，也会提高挤压螺杆的整体强度，延长挤压螺杆的使用寿命。
本发明第二方面的实施例提出了一种挤压组件，用于食物料理机，所述挤压组件机包括第一桶体，所述第一桶体的一端设置有入料口，所述第一桶体的另一端上设置有排渣口，所述第一桶体的侧壁上设置有排汁口；第一方面任一实施例提供的挤压螺杆，所述挤压螺杆能够转动地安装在所述第一桶体内，所述挤压螺杆的进料段与所述入料口配合，所述挤压螺杆的排渣段与所述排渣口配合，其中，所述排汁口设置在所述第一桶体与所述挤压螺杆的挤压段相对应的侧壁上。
根据本发明的实施例的挤压组件，可用于包括粉碎组件的食物料理机，从而可利用粉碎组件将食物粉碎，而粉碎后的食物从入料口进入到挤压组件内，并由挤压组件完成挤汁排渣过程，即将食物的粉碎和挤汁排渣过程分开进行，而由于挤压组件主要利用上述第一方面任一项实施例提供的挤压螺杆，来进行挤汁排渣，从而本发明第二方面的实施例提供的挤压组件具有上述任 一实施例提供的挤压螺杆的全部有益效果。
在上述技术方案中，优选地，所述第一桶体对应所述排渣段的内侧壁上设置有向所述排渣口延伸的排渣斜面，所述排渣斜面用于将食物渣引导至所述排渣口。
在该技术方案中，可将第一桶体设置有排渣口的处的壁设置成斜面，以形成排渣斜面，从而可利用该排渣斜面将食物渣引导至排渣口并从排渣口处顺畅排出，从而可有效缓解食物渣易堵塞排渣口的现象。
在上述技术方案中，优选地，所述挤压螺杆的进料段位于所述入料口的下方；所述入料口在所述挤压螺杆的径向上的投影宽度L1大于所述进料段的直径，所述入料口在所述挤压螺杆的轴向上的投影长度为L2，所述投影长度L2的值为：3.8mm≤L2≤19.9mm。
在该技术方案中，将入料口与进料端上下设置，从而至少可利用粉碎后的食物的重力使粉碎后的食物进入到挤压组件内，以便能利用挤压组件实现对粉碎后的食物的挤汁排渣，同时，还可通过进料段的杆体尺寸合理设置入料口的尺寸，以使粉碎后的食物更易进入到杆体的进料段上，其中，优选地，所述入料口的投影在挤压螺杆的径向上的宽度大于进料段的直径，具体地，比如所述入料口的投影在挤压螺杆的径向上的宽度等于进料段的螺杆直径加上1mm至5mm，而入料口的投影在挤压螺杆的轴向上的长度L2优选在3.8mm至19.9mm的范围内。
在上述技术方案中，优选地，所述挡料板伸入到所述入料口内，且挡料板距所述入料口远离所述挤压螺杆的端面之间的距离E在1mm至10mm的范围内。
在上述技术方案中，优选地，所述排汁口处设置有过滤片，所述过滤片与所述挤压螺杆的螺纹接触或所述过滤片与所述挤压螺杆的螺纹之间设置有一间隙a，所述间隙a小于食物渣的颗粒大小。
在该技术方案中，通过设置过滤片可防止食物渣从排汁口排出，同时还可通过食物渣的颗粒大小合理设置过滤片与挤压螺杆之间的距离，从而可利用挤压螺杆与过滤片之间的摩擦来实现过滤片的自动清洗。
在上述技术方案中，优选地，所述间隙a的值为：0.2mm≤a≤5mm。
在该技术方案中，将间隙a的值设置在0.2mm至5mm的范围内，而日常生活中的豆子等食物在碾压或切削碎后，其食物渣的颗粒大小一般在0.1mm至3mm左右，具体地，不同食物越有差异，因而将间隙a设置在0.2mm至5mm的范围内，使其与食物处理后的食物渣的大小相适应，因而便能够利用挤压螺杆与过滤片之间的摩擦来实现对过滤片上的食物渣的自动清洗。
其中，优选地，所述过滤片为金属过滤片，因为金属过滤片的硬度及耐磨性较好，因而在利用挤压螺杆来对过滤片进行清洗时，可防止过滤片因强度不够而损坏的情况发生。
在上述技术方案中，优选地，所述过滤片与所述第一桶体为一体式结构或所述过滤片能够拆卸地安装在所述排汁口处。在实现防止食物渣从排汁口排出的原则下，过滤片即可以与第一桶体设置成一体式结构，当然过滤片也可拆卸地设置在第一桶体的排汁口处，而将过滤片可拆卸地设置在第一桶的排汁口处，易于对过滤片进行维修更换。
在上述技术方案中，优选地，所述排渣口处设置有挤压片。
在该技术方案中，在排渣口处设置挤压片能够进一步对食物进行挤压，以使食物的汁渣分离的更彻底，从而能够挤压出更多的食物汁，进而能够提高食物料理机的出汁率。
本发明第三方面的实施例提出了一种食物料理机，包括：进料口；粉碎组件，所述粉碎组件包括第二桶体和位于第二桶体内的粉碎装置，所述第二桶体与所述进料口导通，所述粉碎装置用于粉碎食物；第二方面任一项实施例所述的挤压组件，所述第二桶体与所述挤压组件的入料口相互连通；主机组件，所述粉碎组件和所述挤压组件安装在所述主机组件上，所述主机组件包括驱动组件，所述驱动组件用于驱动所述粉碎装置粉碎食物，及用于驱动挤压组件的挤压螺杆挤汁排渣。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范 围并不受下面公开的具体实施例的限制。
下面参照图1至图10描述根据本发明一些实施例提供的挤压螺杆、挤压组件及食物料理机。
如图1至图3所示，本发明第一方面的实施例提供了一种挤压螺杆14，包括：杆体141，杆体141包括进料段1411、与进料段1411连接的挤压段1412和与挤压段1412连接的排渣段1413；其中，杆体141的横截面的面积从进料段1411至挤压段1412逐渐增大。
根据本发明第一方面的实施例提供的挤压螺杆14，挤压螺杆14的杆体141包括依次连接的进料段1411和挤压段1412和排渣段1413，排渣的受力方向沿着杆体141的轴向方向，且杆体141的推力方向也沿着杆体141的轴向方向，从而使得挤压螺杆14的挤汁与排渣的受力方向与杆体141的推力方向一致，从而可增大挤汁力和排渣力，使得排渣口122处的食物渣更易被排出，进而即可减少食物渣堵塞排渣口122的现象，同时，由于挤汁力增大，因而会有更多的食物汁被挤压出来，因而一方面可提高食物的出汁率，另一方面由于食物渣中含有的食物汁更少，从而能够使得食物渣更干，进而可避免出现食物渣不干的现象。同时，杆体141的横截面的面积从进料段1411至挤压段1412逐渐增大，即杆体141从进料端至挤压段1412逐渐变粗，该种设置在将挤压螺杆14安装在食物料理机的第一桶体12内时，挤压螺杆14与第一桶体12的内壁配合，以形成挤压通道以对食物进行夹击挤压，而杆体141从进料端至挤压段1412逐渐变粗，从而使得挤压螺杆14与第一桶体12的内壁形成的挤压通道能够逐渐变窄，进而能够增大挤压螺杆14与第一桶体12的内侧壁作用于食物上的挤压力度，以提高出汁率。
其中，图1至图3中的虚线为挤压螺杆14的进料段1411和挤压段1412或挤压段1412与排渣段1413之间的分界线。
在上述技术方案中，优选地，挤压螺杆14还包括：安装轴，杆体141套设在安装轴上，用于安装杆体。
在该技术方案中，可利用安装轴来实现挤压螺杆14与电机等驱动组件之间的驱动连接，从而挤压螺杆14便能够在电机等驱动组件的驱动下转动以使食物的汁渣分离。
在上述技术方案中，优选地，如图1至图3所示，排渣段1413的横截面的面积从靠近挤压段1412的一端向远离挤压段1412的一端逐渐减小。
在该技术方案中，挤压螺杆14的横截面的面积从靠近挤压段1412的一端向远离挤压段1412的一端逐渐减小，即是说挤压螺杆14的杆体141在出渣段时逐渐内收，该种设置挤压螺杆14的杆体141在出渣段时逐渐内收，从而使得杆体141的出渣段与第一桶体12的内侧壁之间的间隙增大，进而能够减小挤压螺杆14和第一桶体12对食物渣的阻力，以使食物能够顺利排出，进而即可防止出现食物渣堵塞排渣口122的现象。
在上述技术方案中，优选地，如图1至图3所示，杆体141的进料段1411和挤压段1412上设置有螺纹142，螺纹142的螺距从进料段1411至挤压段1412逐渐减小。
在该技术方案中，螺纹142能够在杆体141上形成螺旋槽，从而能够利用该螺旋槽引导食物从进料段1411依次向挤压段1412、排渣段1413推进，并从排渣段1413排出。同时，螺纹142的螺距从进料段1411至挤牙段逐渐减小，即挤压螺杆14的容积率逐渐减小，因而挤压螺杆14对食物的压缩率逐渐增大，因而该种设置也能够提高挤压螺杆14的挤汁力度，以提高出汁率。
在上述技术方案中，优选地，挤压螺杆14的压缩比为A，压缩比A的值为：1.8≤A≤3.6，进一步优选地，压缩比A在2.5至3的范围内，其中，螺杆的压缩比指的是进料段1411上的第一个螺距C1的容积与挤压段1412最后一个螺距C2的容积之比，而挤压螺杆14的螺距指的是相邻两个螺纹142之间沿杆体141轴向方向的距离，螺距的容积指的是该段距离中上可容纳的食物量。
在上述技术方案中，优选地，如图1至图3所示，杆体141的进料段1411上设置有多个压料平面144。
在该技术方案中，可将挤压螺杆14的进料段1411上的第一个螺纹142和第二个螺纹142之间的杆段切成平面，以形成压料平面144，从而更利于该压料平面144将粉碎后的食物引导至挤压螺杆14所在的第一桶体12内。
在上述技术方案中，优选地，如图2和图3所示，进料段1411上设置有挡料板143，螺纹142从挡料板143处向挤压段1412延伸，挡料板143靠近 螺纹142的面上具有导向斜面。
在该技术方案中，可在进料段1411上设置一个挡料板143，并利用该挡料板143与第一个螺纹142形成一个容料腔，从而粉碎后的食物能够直接落入到该容料腔内，而将挡料板143靠近螺纹142的一面上设置导向斜面，能够减少挡料板143对粉碎后的食物的阻力，以利于粉碎后的食物进入到容料腔内。
在上述技术方案中，优选地，螺纹142与杆体141连接的一端的宽度为D1，D1的值为：5mm≤D1≤12.99mm。
在该技术方案中，通过将螺纹142与杆体141连接的一端(即螺纹142的根部)的宽度设置在大于等于5mm小于等于12.99mm的范围内，使得螺纹142与杆体141具有一定的连接宽度，因而能够提高螺纹142与杆体141之间的连接强度，从而即可防止挤压螺杆14的螺纹142在挤汁排渣过程中断裂的情况发生，进而能够提高挤压螺杆14的整体强度，延长挤压螺杆14的使用寿命。
在上述技术方案中，优选地，螺纹142远离杆体141的一端的宽度为D2，D2的值为：1mm≤D2≤4.99mm。
在该技术方案中，通过将螺纹142远离杆体141的一端(即螺纹142的端部)的宽度设置在大于等于1mm小于等于4.99mm的范围内，使得螺纹142的端部宽度较小，因而能够更快速地引导粉碎后的食物沿着挤压螺杆14依次从进料段向挤压段及排渣段移动，进而提高能够挤压螺杆14的挤汁排渣效率。
在上述技术方案中，优选地，螺纹142在杆体141的径向上的投影高度为H，投影高度H的值为：0.5mm≤H≤13.99mm。
在该技术方案中，通过将螺纹142在杆体141的径向上的投影高度设置在大于等于0.5mm小于等于13.99mm的范围内一方面使得螺纹142具有一定的高度，因而便能够与杆体141围成具有一定容积的螺旋槽，而粉碎后的食物从进料段进入到该螺旋槽内，并沿着螺旋槽逐渐向排渣段移动，进而即可完成挤汁排渣，同时将螺纹142在杆体141的径向上的投影高度设置在大于等于0.5mm小于等于13.99mm的范围内，不会使得螺纹142的高度过高， 因而能够确保螺纹142的整体强度，进而便能够适当地提高挤压杆对食物的挤压程度，以提高食物的出汁率，同时，螺纹142的强度提高后，也会提高挤压螺杆14的整体强度，延长挤压螺杆14的使用寿命。
如图4至图6所示，本发明第二方面的实施例提出了一种挤压组件，用于食物料理机，挤压组件机包括第一桶体12，第一桶体12的一端设置有入料口18，第一桶体12的另一端上设置有排渣口122，第一桶体12的侧壁上设置有排汁口121；第一方面任一实施例提供的挤压螺杆14，挤压螺杆14能够转动地安装在第一桶体12内，挤压螺杆14的进料段1411与入料口18配合，挤压螺杆14的排渣段1413与排渣口122配合，其中，排汁口121设置在第一桶体12与挤压螺杆14的挤压段1412相对应的侧壁上。
根据本发明的实施例的挤压组件，可用于包括粉碎组件的食物料理机，从而可利用粉碎组件将食物粉碎，而粉碎后的食物从入料口18进入到挤压组件内，并由挤压组件完成挤汁排渣过程，即将食物的粉碎和挤汁排渣过程分开进行，而由于挤压组件主要利用上述第一方面任一项实施例提供的挤压螺杆14，来进行挤汁排渣，从而本发明第二方面的实施例提供的挤压组件具有上述任一实施例提供的挤压螺杆14的全部有益效果。
在上述技术方案中，如图4和图5所示，优选地，第一桶体12对应排渣段的内侧壁上设置有向排渣口122延伸的排渣斜面123，排渣斜面123用于将食物渣引导至排渣口122。
在该技术方案中，可将第一桶体12设置有排渣口122的处的壁设置成斜面，以形成排渣斜面123，从而可利用该排渣斜面123将食物渣引导至排渣口122并从排渣口122处顺畅排出，从而可有效缓解食物渣易堵塞排渣口122的现象。
在上述技术方案中，优选地，如图4所示，挡料板伸入到所述入料口18内，且挡料板距入料口远离挤压螺杆14的端面之间的距离E在1mm至10mm的范围内。
在上述技术方案中，优选地，如图4至图6所示，挤压螺杆14的进料段1411位于入料口18的下方；入料口18在挤压螺杆14的径向上的投影宽度L1大于进料段1411的直径，入料口18在挤压螺杆14的轴向上的投影长度 为L2，投影长度L2的值为：3.8mm≤L2≤19.9mm。
在该技术方案中，将入料口18与进料端上下设置，从而至少可利用粉碎后的食物的重力使粉碎后的食物进入到挤压组件内，以便能利用挤压组件实现对粉碎后的食物的挤汁排渣，同时，还可通过进料段1411的杆体141尺寸合理设置入料口18的尺寸，以使粉碎后的食物更易进入到杆体141的进料段1411上，其中，优选地，入料口18的投影在挤压螺杆14的径向上的宽度大于进料段1411的直径，具体地，比如入料口18的投影在挤压螺杆14的径向上的宽度等于进料段1411的螺杆直径加上1mm至5mm，而入料口18的投影在挤压螺杆14的轴向上的长度L2优选在3.8mm至19.9mm的范围内。
在上述技术方案中，优选地，如图4所示，排汁口121处设置有过滤片15，过滤片15与挤压螺杆14的螺纹142接触或过滤片15与挤压螺杆14的螺纹142之间设置有一间隙a，间隙a小于食物渣的颗粒大小。
在该技术方案中，通过设置过滤片15可防止食物渣从排汁口121排出，同时还可通过食物渣的颗粒大小合理设置过滤片15与挤压螺杆14之间的距离，从而可利用挤压螺杆14与过滤片15之间的摩擦来实现过滤片15的自动清洗。
在上述技术方案中，优选地，间隙a的值为：0.2mm≤a≤5mm。
在该技术方案中，将间隙a的值设置在0.2mm至5mm的范围内，而日常生活中的豆子等食物在碾压或切削碎后，其食物渣的颗粒大小一般在0.1mm至3mm左右，具体地，不同食物越有差异，因而将间隙a设置在0.2mm至5mm的范围内，使其与食物处理后的食物渣的大小相适应，因而便能够利用挤压螺杆14与过滤片15之间的摩擦来实现对过滤片15上的食物渣的自动清洗。
其中，优选地，过滤片15为金属过滤片，因为金属过滤片的硬度及耐磨性较好，因而在利用挤压螺杆14来对过滤片15进行清洗时，可防止过滤片因强度不够而损坏的情况发生。
在上述技术方案中，优选地，过滤片15与第一桶体12为一体式结构或过滤片15能够拆卸地安装在排汁口121处。在实现防止食物渣从排汁口121排出的原则下，过滤片15即可以与第一桶体12设置成一体式结构，当然过 滤片15也可拆卸地设置在第一桶体12的排汁口121处，而将过滤片15可拆卸地设置在第一桶的排汁口121处，易于对过滤片15进行维修更换。
在上述技术方案中，优选地，排渣口122处设置有挤压片16。
在该技术方案中，在排渣口122处设置挤压片16能够进一步对食物进行挤压，以使食物的汁渣分离的更彻底，从而能够挤压出更多的食物汁，进而能够提高食物料理机的出汁率。
如图7至图10所示，本发明第三方面的实施例提出了一种食物料理机，包括：进料口；粉碎组件，粉碎组件包括第二桶体11和位于第二桶体11内的粉碎装置13，第二桶体11与进料口导通，粉碎装置13用于粉碎食物；第二方面任一项实施例的挤压组件，第二桶体11与挤压组件的入料口18相互连通；主机组件2，粉碎组件和挤压组件安装在主机组件2上，主机组件2包括驱动组件21，驱动组件21用于驱动粉碎装置13粉碎食物，及用于驱动挤压螺杆14挤汁排渣，其中，粉碎组件和挤压组件组成桶体组件，桶体组件安装在主机组件2上。
根据本发明的实施例的食物料理机，食物从进料口进入到第二桶体11内后由粉碎装置13与第二桶体11的侧壁配合以将食物粉碎，粉碎后的食物在粉碎装置13的作用下从入料口18进入到第一桶体12内，然后由挤压螺杆14挤压，以使食物的汁渣分离。该技术方案将食物的粉碎过程和挤汁排渣过程分开进行，而在粉碎过程中，由于不需要挤汁排渣，因此，第二桶体11内不用设置滤网以及旋转刷等部件，从而使得第二桶体11内的食物能够在第二桶体11与粉碎装置13的共同作用下被粉碎，同时在挤汁排渣过程中可将挤压螺杆14大致水平设置，即可将挤汁排渣系统设置成卧式，从而可非常便于将食物的汁渣分离，该种设置一方面能够确保食物料理机的出汁率，另一方面能够避免使用滤网、旋转刷等零部件，从而使得食物料理机的结构简单且易于安装，同时由于取消了滤网，因而能够降低用户的清洗难度，进而能够提升用户体验。
在上述技术方案中，优选地，如图7至图9所示，第二桶体11的尺寸从靠近进料口的一端向靠近入料口18的一端逐渐减小。
在该技术方案中，可将第二桶体11设置成上大下小的形状，具体地，若 第二桶体11呈圆形，则第二桶体11的直径从上至下逐渐减小，若第二桶体11为非圆形，则第二桶体11的横截面的宽度和长度从上至下逐渐减小。该种设置能够将食物越切越碎，具体地比如在食物刚进入第二桶体11时，食物的颗粒较大，第二桶体11的内侧壁与粉碎装置13之间的距离与食物的颗粒相适应，而在粉碎装置13与第二桶体11的作用下，食物逐渐被粉碎成较小的颗粒并逐渐向入料口18处移动，因而将靠近入料口18处的间隙设置的较小，从而一方面使其能够与此处的食物的颗粒大小相适应，另一方面使得此处的食物能够在粉碎装置13作用下被进一步被粉碎成更小的颗粒，从而便能够实现食物的逐级充分粉碎，进而便能够提高食物的出汁率。
在上述技术方案中，优选地，如图10所示，驱动组件21包括：电机211，电机211上设置有电机轴；传动组件，传动组件至少包括：第一传动件212，第一传动件212与电机轴驱动连接，第一传动件212上设置有第一驱动轴213，第一驱动轴213与粉碎装置13连接，用于驱动粉碎装置13粉碎食物；第二传动件214，第二传动件214与电机轴驱动连接，第二传动件214上设置有第二驱动轴215，第二驱动轴215与挤压螺杆14连接，用于驱动挤压螺杆14挤汁排渣；其中，第一驱动轴213竖直设置，第一驱动轴213与第二驱动轴215之间呈一预设角度β，预设角度β的值为：60°≤β≤135°。
