本发明所要解决的技术问题是提供一种在搅拌食物过程中防止驱动电机晃动的食物搅拌机及其驱动装置。
本发明的目的是通过以下技术方案来实现的：
本发明的一个方面是：公开一种食物搅拌机，包括搅拌刀组、壳体以及安装在所述壳体内的驱动装置，所述驱动装置与所述搅拌刀组传动连接用于驱动所述搅拌刀组，所述驱动装置包括驱动电机和设置在所述驱动电机两端的弹性垫片，所述壳体内设置有用于放置所述驱动电机的卡槽，所述驱动电机通过所 述弹性垫片的挤压变形放置到所述卡槽内。
优选的，所述壳体内表面设置有用于限位所述弹性垫片的限位圈，当所述弹性垫片放置在所述卡槽内时，所述弹性垫片的侧面边沿和所述限位圈贴合。限位圈起到限位作用，对弹性垫片的侧面起到压合作用。
优选的，所述限位圈顶部向上延伸有卡板，当所述弹性垫片放置在所述卡槽内时，所述弹性垫片的侧面中部和所述卡板贴合。在限位圈顶部延伸卡板对弹性垫片起到进一步限位作用，对弹性垫片的侧面起到进一步的压合作用，进而使得弹性垫片对驱动电机的限位作用更好。
优选的，所述卡板和壳体内表面之间设置有加强筋。设置加强筋增加卡板强度，防止卡板因受到振动而随之振动，进而使得卡板对弹性垫片的限位作用好。
优选的，所述加强筋分别连接所述卡板、限位圈和壳体内表面。这样卡板、限位圈及壳体三者相互之间通过加强筋实现连接关系，相互之间增加强度；当然，加强筋也可直接连接壳体内表面和卡板。
优选的，所述壳体内表面设置设有卡条，所述卡条位于所述卡槽内，当所述弹性垫片放置在所述卡槽内时，所述卡条和所述弹性垫片边沿的周缘面贴合。卡条对弹性垫片起到限位、固定作用，防止弹性垫片转动。
优选的，所述弹性垫片为环形结构，所述卡条沿所述弹性垫片的轴向设置。这样对弹性垫片限位、固定效果更佳。
优选的，所述卡条为多个，均布设置，形成环形结构的内径小于或等于所述弹性垫片的直径。这样对弹性垫片具有挤压作用力，使得弹性垫片牢固的固定在壳体内部。
优选的，所述卡条一端和所述限位圈连接，另一端连接有一加强板，所述加强板的高度小于或等于所述卡条的高度，且所述卡条的高度小于所述限位圈的高度。通过加强板相互增加限位圈和卡条的强度。
本发明的另一个方面：公开一种驱动装置，用于驱动如上所述的食物搅拌 机的搅拌刀组，所述驱动装置与所述搅拌刀组传动连接用于驱动所述搅拌刀组，所述驱动装置包括驱动电机和设置在所述驱动电机两端的弹性垫片。
与现有技术相比，本发明的技术效果是：驱动电机两端设置有弹性垫片，并通过对弹性垫片的挤压形变放置到壳体的卡槽内，弹性垫片在挤压形变过程中产生弹力直接作用于驱动电机的两端，增加对驱动电机两端的紧固效果，防止驱动电机和弹性垫片之间产生空隙，进而防止驱动电机在工作过程中产生晃动，进一步使得驱动电机驱动的搅拌刀组稳定的转动。

下面结合附图和较佳的实施例对本发明作进一步说明。
下面参考图3至图5描述本发明实施例一的开关装置，此开关装置200与开关配合，用于控制开关。本实施例的开关装置配合一电路板使用，参见图1和图2所示，开关装置200和电路板140配合固定，且开关直接安装固定在电路板140，这样就方便开关装置200直接固定到电路板140上与开关进行配合，从而控制该电路板上的开关。
需要说明的是，对于本领域技术人员而言，本实施例的开关装置仅仅依开关 装置固定在电路板上为例进行说明，并不限于此，当然，开关装置也可以固定在其他位置用于控制开关。例如：将开关通过导线和电路板电性连接，且开关固定在一壳体上，将开关装置安装固定在壳体上，并与开关配合，用于控制此开关。
具体的，本实施例的电路板140安装于一食物搅拌机内，如图8和图9所示，本实施例依电路板安装于此食物搅拌机100内为例进行说明。需要说明的是，对于本领域技术人员而言，此电路板可安装于其他电器中，比如安装于一台灯内等等。
如图3至图5所示，本实施例公开一种开关装置200，用于安装固定在电路板140上，并与固定在所述电路板140上的开关150配合，所述开关装置200包括固定在所述电路板140上的按键架220和活动的连接在所述按键架220上的按键210，且所述开关150位于所述按键架220内，所述按键210在所述按键架220上活动以控制所述开关150。
本实施例的按键架220固定连接到电路板140上，按键210活动连接到按键架220上，并通过按键210在按键架220上的活动来控制电路板140上的开关150，以便使用者通过按键210控制开关150，本发明通过按键架220将按键210直接安装固定于电路板140上，且使得按键210和开关150直接配合，从而方便生产、组装，直接将配合连接完成后的电路板140与壳体装配即可，相比现有技术，无需额外配合，加快了生产、组装过程。
需要说明的是，本实施例的开关装置200为两个，如图1所示；以及开关140也为两个，如图2所示；本实施例一个开关装置200和一个开关相配合。当然，本实施例仅在电路板140上设置一个开关150，并由一个开关装置200与其配合也是可以的。
其中，所述按键架220包括与所述电路板140固定连接的底端230和与所述底端230相对的顶端240。本实施例按键架220和电路板140之间可拆卸的固定连接。
具体的，本实施例按键架220和电路板140之间通过卡接固定连接。当然，对于本领域技术人员而言，通过其他可拆卸的方式进行固定连接也是可以的，比如通过螺丝固定连接。按键架220上设置有卡扣227，对应的，电路板140上设置有用于放置所述卡扣227的卡孔141，卡扣和卡孔卡接配合容易实现。
进一步的，按键架220包括位于所述顶端240和底端230之间的第一壁221、第二壁222、第三壁223及第四壁224；所述第一壁221和第二壁222相对设置，所述第三壁223和第四壁224相对设置，所述第三壁223和第四壁224上分别设置有卡扣227，此两个卡扣227分别位于第三壁223和第四壁224的外表面上。所述卡扣227位于所述按键架220的底端230，且突出于所述第一壁221和第二壁222。对应的，所述电路板140上设置有用于放置所述卡扣227的两个卡孔141，此两个卡孔141分别位于开关150的两侧位置。当所述卡扣227插入到所述卡孔141内，同时扣合到所述电路板140上时所述第一壁221和第二壁222顶压到所述电路板140上。这是按键架和电路板可拆卸固定连接的一种具体方式，按键架的其中两个相对侧壁和另外两个相对侧壁之间形成间隔，这样使得按键架的四个侧壁都具有弹性，在和电路板进行固定连接或拆卸过程中通过侧壁的弹性更加容易实现。
更进一步的，所述第三壁223与第一壁221和第二壁222之间相互间隔设置，所述第四壁224与第一壁221和第二壁222之间相互间隔设置，两个所述卡孔141之间的最小距离小于所述第三壁223和第四壁224之间的距离；两个所述卡孔141之间的最大距离小于两个所述卡扣227之间的最大距离，且大于所述第三壁223和第四壁224之间的距离。第三壁223、第四壁224分别与第一壁221和第二壁222之间相互间隔设置，从而使得第三壁223和第四壁224具有弹性，通过第三壁223及第四壁224的弹性形变，调整卡扣227，以便将卡扣227插入到对应的卡孔141内；而且在取出卡扣227的过程中，可以通过挤压卡扣227，同样通过第三壁223及第四壁227的弹性形变以便使得卡扣227从卡孔141内脱离。
其中，所述第三壁223和第四壁224的根部分别设置有加强筋。加强筋增加第三壁223、第四壁224的强度，防止第三壁223和第四壁224在产生形变时折断。
其中，所述顶端240设置有第一通孔225和第二通孔226，所述按键210包括按键帽213、触杆211和限位杆212，所述触杆211和限位杆212都位于所述按键帽213的同一面上，所述触杆211用于插入到所述第一通孔225内，且用于控制所述开关150；所述限位杆212用于插入到所述第二通孔226内，所述限位杆212顶部设置有使所述限位杆212限位于所述第二通孔226内的限位块214。按键210与按键架220相互配合的一种具体方式，通过限位杆212及触杆211分别插入到第二通孔226和第一通孔225内，可使得限位杆212及触杆211分别在第二通孔226和第一通孔225内进行活动，从而使得按键210和按键架220之间的活动连接稳定，以便在控制按键210的过程中更加稳定的控制触杆211来控制开关150。
进一步的，所述限位杆212顶部设置有开口215使所述限位杆212顶部形成等大的两个部分；所述限位杆212顶部两部分向所述开口方向压缩，且两部分接触时的大小小于或等于所述第二通孔226的大小。限位杆212顶部设置开口215以便限位杆212顶部被开口215分开的两个部分相互之间具有弹性，从而在将限位杆插入到第二通孔内时可通过对限位杆顶部的挤压使得限位杆顶部产生形变以便限位杆顺利的插入到第二通孔内。而且，当限位杆插入到第二通孔内后，同时限位块突出到第二通孔外，这样开口两侧的两个部分恢复原状，这样限位块的大小就大于第二通孔的大小，从而限位块和第二通孔周围的侧壁相互配合实现限位的功能。
其中，限位杆212顶部还设置有倒角，进一步便于限位杆212插入到第二通孔内。
其中，所述按键架220顶部内表面设置有用于限位所述触杆211的限位板，所述限位板为两个，分别位于所述触杆的两相对侧。限位板对触杆起到限位作 用，这样触杆的两侧由限位板限位，触杆另外两侧由按键架的侧壁限位，从而触杆的四面同时被限位，这样触杆在活动过程中更加稳定，不易倾斜，进而使得触杆更加稳定的触发开关。
其中，所述按键架220顶部设置有用于限位所述按键帽213的限位环250，所述限位环250的高度等于所述触杆211触发所述开关150的距离。设置限位环250防止按压力度过大而损坏开关150。具体的，限位环250包括围绕第一通孔225设置的第一限位环229和围绕第二通孔226设置的第二限位环228，第一限位环和第二限位环高度相同。本实施例设置两个限位环对按键帽的限位效果更佳。当然，本实施例仅设置其中一个限位环也是可以的。
本实施例按键210和按键架220由限位杆212起到固定连接的作用的，以便按键210在按键架220上活动，进而通过触杆211来控制开关150。
作为本发明实施例二，如图6和图7所示，本实施例与实施例一的区别在于：仅在按键帽213上设置一个限位杆212，而不设置触杆。对应的，按键架220的顶部240仅仅设置第二通孔226，而不设置第一通孔225。这样，在将按键架220安装固定在电路板上时将第二通孔226和开关相对应，从而限位杆212插入到第二通孔226内后可直接控制开关，而无需再通过额外设置触杆来实现对开关的控制。本实施例就简化了按键及按键架的结构，以便生产和配合；但是，相比实施例一，实施例一设置触杆来控制开关的结构更加稳定。
本实施例的其他结构及技术效果分别与实施例一相同，这里不再一一详述。
下面参考图8至图11详细描述本发明的食物搅拌机，此食物搅拌机100包括搅拌刀组130、壳体120以及安装在所述壳体120内的驱动装置110，所述驱动装置110与所述搅拌刀组130传动连接用于驱动所述搅拌刀组130。结合图1至图5所示，所述食物搅拌机100还包括开关150和用于控制所述开关150的开关装置200，所述开关150设置在一电路板140上，所述电路板140与所述驱 动装置110电性连接；所述开关装置200包括固定在所述电路板140上的按键架220和活动的连接在所述按键架220上的按键210，且所述开关150位于所述按键架220内，所述按键210在所述按键架220上活动以控制所述开关150。
此食物搅拌机100内的开关装置优选设置为实施例一中的开关装置，实施例一中的电路板140安装固定在壳体120内，如图9所示。当然，本发明的食物搅拌机也可以将开关装置设置成实施例二中的开关装置。
开关装置200的结构、技术效果及连接关系详见实施例一。
其中，所述驱动装置110包括驱动电机111和设置在所述驱动电机111两端的弹性垫片112，所述壳体120内设置有用于放置所述驱动电机111的卡槽121，所述驱动电机111通过所述弹性垫片112的挤压变形放置到所述卡槽121内。具体的，驱动电机111两端设置有弹性垫片112，并通过对弹性垫片112的挤压形变放置到壳体120的卡槽121内，弹性垫片112在挤压形变过程中产生弹力直接作用于驱动电机111的两端，增加对驱动电机111两端的紧固效果，防止驱动电机111和弹性垫片112之间产生空隙，进而防止驱动电机111在工作过程中产生晃动，进一步使得驱动电机驱动的搅拌刀组稳定的转动。
其中，驱动电机111的一端设置有输出轴113，通过输出轴113与搅拌刀组130传动连接驱动搅拌刀组130。
其中，如图10所示为壳体的部分结构示意图，所述壳体120内表面设置有用于限位所述弹性垫片112的限位圈122，当所述弹性垫片112放置在所述卡槽121内时，所述弹性垫片112的侧面边沿和所述限位圈122贴合。限位圈122起到限位作用，对弹性垫片112的侧面起到压合作用。
进一步的，所述限位圈122顶部向上延伸有卡板123，当所述弹性垫片112放置在所述卡槽121内时，所述弹性垫片112的侧面中部和所述卡板123贴合。在限位圈122顶部延伸卡板123对弹性垫片112起到进一步限位作用，对弹性垫片的侧面起到进一步的压合作用，进而使得弹性垫片对驱动电机的限位作用更好。
更进一步的，所述卡板123和壳体120内表面之间设置有加强筋124。设置加强筋增加卡板强度，防止卡板因受到振动而随之振动，进而使得卡板对弹性垫片的限位作用好。具体的，所述加强筋124分别连接所述卡板123、限位圈122和壳体120内表面。这样卡板123、限位圈122及壳体120三者相互之间通过加强筋124实现连接关系，相互之间增加强度；当然，加强筋124也可直接连接壳体120内表面和卡板123。
其中，所述壳体120内表面设置设有卡条125，所述卡条125位于所述卡槽121内，当所述弹性垫片112放置在所述卡槽121内时，所述卡条125和所述弹性垫片112边沿的周缘面贴合。卡条125对弹性垫片起到限位、固定作用，防止弹性垫片转动。
具体的，所述弹性垫片112为环形结构，所述卡条125沿所述弹性垫片112的轴向设置。这样对弹性垫片限位、固定效果更佳。所述卡条125为多个，均布设置，形成环形结构的内径小于或等于所述弹性垫片112的直径。这样对弹性垫片具有挤压作用力，使得弹性垫片牢固的固定在壳体内部。
进一步的，所述卡条125一端和所述限位圈122连接，另一端连接有一加强板126，所述加强板126的高度小于或等于所述卡条125的高度，且所述卡条125的高度小于所述限位圈122的高度。通过加强板相互增加限位圈和卡条的强度。
其中，电路板140通过导线300连接一插头，通过插头实现与外电的电性连接，通过外电为食物搅拌机100供电。
本发明的驱动装置安装于如上所述的食物搅拌机中，用于驱动食物搅拌机的搅拌刀组，所述驱动装置与所述搅拌刀组传动连接用于驱动所述搅拌刀组，所述驱动装置包括驱动电机和设置在所述驱动电机两端的弹性垫片。
本发明的驱动装置是依食物搅拌机为例进行说明的，对于本领域技术人员，需要说明的是，本发明的驱动装置并不限于安装于食物搅拌机内，本发明的驱 动装置也可以安装于其他器械中进行使用。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
