本发明涉及电风扇装置，尤其是一种电风扇手调式标识摆角调节装置。
背景技术
现有技术中，可调摆角电风扇主要是通过改变曲柄摇杆机构中曲柄的长度实现摆角的调整，现有技术一中国专利号99236154.0技术中，展示了一种电风扇定量标识摆角调节装置，包括在大齿轮内置限位滑槽—滑块齿条曲柄与芯轴齿轮啮合组成可变长曲柄机构，在空心轴伸出电机罩壳外接装带刻度盘的大圆轮，在芯轴伸出电机罩壳外接装调角旋钮，在调角旋钮与大圆轮之间设置一组弹性紧定接触装置，使用者可根据大圆轮刻度盘标识，扭动调角旋钮，驱动滑块齿条曲柄按标识作出等量变长位移，从而获得任意角度的送风摆角。但是，其在大齿轮内置限位滑槽—滑块齿条曲柄与芯轴齿轮啮合组成的往复式可变长曲柄机构，是一种要在滑槽往复两端设置限位端阻挡面的内限式阻挡结构，一旦使用者扭动调角旋钮方向不对或扭力过大，致芯轴齿轮与齿条碰到限位端阻挡面受阻，产生过冲力矩，会出现“扫齿”现象，造成调角失败；此外，在“大圆轮内有形孔，形孔内有弹簧装置，弹簧装置与调角旋钮凹凸体装配成弹性紧密接触”的装配结构，是一种将弹簧散件留转到电风扇总装生产线，待安装完电机罩壳后，才能后续安装弹簧的散件式二次组装生产工艺，存在明显违反电风扇制造业安规和业内行规的缺点。
针对以上缺点，现有技术二中国专利申请号202011159133.5技术中，公开了一种电风扇手调式双向分级标识摆角调节装置，在大齿轮内腔设置一种由偏心齿轮圆盘曲柄—中心(轴)齿轮组成的可360度双向无阻挡回转的回转式可调曲柄结构，在空心轴与标识盘之间设置一组带始点基准具唯一性定位，且可徒手装拆的标识盘中继连接装置，在中心轴与调角旋钮之间设置一组带始点定位可相对标识盘作360度双向无阻挡旋转，且可徒手装拆的调角旋钮中继连接装置，从而建立起一种可按双向分级标识指示，双向360度无阻挡回转式改变偏心齿轮圆盘曲柄偏心距位移长度的手调式双向分级标识摆角调节装置，既消除了现有技术一滑块齿条与芯轴齿轮的扫齿现象，也解决了标识盘与调角旋钮以符合业内行规生产工艺可靠完成装配问题，使用者在电风扇外能按标识盘双向分级标识快速可靠地调角。但是，由于中心(轴)齿轮驱动偏心齿轮圆盘曲柄回转产生的回转式曲柄偏心距位 移长度轨迹，与调角旋钮相对标识盘均值标识扭动中心轴的角位移轨迹，是一种非线性的函数式位移关系，在调角旋钮位于标识盘拐点标识或零点标识越接近时扭动调角旋钮，其驱动偏心齿轮曲柄所作出的回转式偏心距位移长度变化越小，反之，当扭动调角旋钮至标识盘零点与拐点的中段标识越接近，其驱动偏心齿轮曲柄所作出的回转式偏心距位移长度变化越大，显然，这种中心(轴)齿轮驱动偏心齿轮圆盘曲柄360度回转使其回转式曲柄偏心距产生的位移长度变化，与标识盘每一级标识显示的均值标识存在不等量的位移差，容易误导使用者操作时偏离预定值，存在调角欠准确的缺点。
发明内容
本发明要解决的技术问题是提供一种在手调式调角过程中，既能避免扫齿也能按标识盘标识准确等量调角的电风扇手调式标识摆角调节装置。
为解决上述技术问题，本发明的电风扇手调式标识摆角调节装置，包括电机罩壳，标识盘，调角旋钮，制有蜗轴套和下轴套的壳体，制有上轴套的壳盖和二级减速机构，第二级减速机构有蜗轴齿轮和大齿轮，大齿轮设有第一内腔，第一内腔置有由第一限位滑槽—滑块齿条曲柄与中心齿轮组成的曲柄调节机构，标识盘置有分级标识的每级标识角位移角度，与中心齿轮的每齿角位移角度相等，空心轴，中心轴，在空心轴上端制有圆形迭级台阶与标识盘之间置有一组具唯一性定位连接的标识盘中继连接装置，在中心轴与调角旋钮之间置有一组具唯一性定位连接的调角旋钮中继连接装置，该调角旋钮中继连接装置由双向连接块以打螺钉固装于中心轴上端构成，大齿轮下端有限位盖，限位盖制有第二限位滑槽，曲柄穿过第二限位滑槽至大齿轮外，在标识盘与调角旋钮之间置有限位槽—限位块机构，限位槽—限位块机构是在标识盘制有圆弧形限位槽，在调角旋钮制有限位块，限位块插入限位槽内，限位槽的既定限位行程等于标识盘既定标识的有效限位行程。
通过在标识盘与调角旋钮之间增设一组限位槽—限位块机构，组成的有既定限位行程的内限式阻挡机构，替代现有技术中调角旋钮与标识盘之间的全旋无阻挡机构，调角中，一旦使用者扭动调角旋钮力量过大或误操作方向相反，致中心轴下端的中心齿轮与滑块齿条将要碰到第一限位滑槽限位端阻挡面时，扭力输入端调角旋钮的限位块首先把调角旋钮牢固阻挡在标识盘限位槽的既定限位端面，使调角旋钮止动，同步制止了中心轴与空心轴下端中心齿轮与滑块齿条的过冲动作位移，从而在结构设置上彻底消除了中心齿轮与滑块齿条因手扭动调角旋钮力量过大或误操作所造成的扫齿现象。
在滑块制有第二内腔，第二内腔内壁制有齿条，中心齿轮插入第二内腔与齿条啮合， 在滑块外壁制有分级凹凸体，分级凹凸体中心距与齿条齿距相等，分级凹凸体顶端与第一限位滑槽槽壁成滑配合，在第一限位滑槽槽壁制有缺口，在大齿轮第一内腔置有弹簧—紧定物装置的紧定物穿过缺口与分级凹凸体成弹性紧定接触，上述紧定物是一端为第一圆弧形凸条另一端为方形块的紧定物，紧定物的第一圆弧形凸条穿过缺口与分级凹凸体成弹性紧定接触。
通过在滑块外壁增加制有一排中心距与齿条齿距相等的分级凹凸体，在第一限位滑槽的常规槽壁中段破开制有缺口，并在缺口位置增设一套弹性紧定物装置，以弹性紧定接触方式顶压分级凹凸体，于是，限定了滑块齿条曲柄只能按分级凹凸体的置定中心距，在第一限位滑槽中，作置定与位移，从而组成一组带分级凹凸体限定位移轨迹的滑块齿条往复式曲柄变长调节机构，由于分级凹凸体中心距与滑块齿条齿距相等，滑块齿条齿距与中心齿轮齿距相等，中心齿轮每齿角位移角度与标识盘每级分级标识角位移角度相等，这样，就组成一套能按标识盘既定分级标识，准确等量地调节滑块齿条曲柄偏心距实际位移长度的电风扇手调式标识摆角调节装置。
在滑块下端面与曲柄之间制有迭级凸块，在上述限位盖沿第二限位滑槽制有延伸滑槽，迭级凸块置入延伸滑槽成滑配合。通过在滑块下端面与曲柄之间增设迭级凸块，在限位盖沿第二限位滑槽增设延伸滑槽，把迭级凸块置入延伸滑槽成滑配合，这样，在滑块齿条曲柄变长调节机构中，形成了由第一限位滑槽—滑块和延伸滑槽—迭级凸块组成的单滑块双平面双滑槽直线导向滑配合架构，增强了曲柄的滑配合垂直稳定性，减少了调角时中心齿轮的横向扭力影响，并提高了曲柄抵御外力冲撞的抗冲击力。
在上述第二级减速机构中，还可以在上述壳体蜗轴套下段壁内沿蜗轴齿轮的齿顶圆面非啮合部分制有圆弧加强套，圆弧加强套的圆弧面与蜗轴齿轮相对应的齿顶圆面呈动配合状态。这样一来，增强了蜗轴齿轮与大齿轮的啮合稳定性，解决了因蜗轴齿轮远端呈单端悬臂状与大齿轮啮合存在稳定性偏低，在手扭调角过程中易产生啮合失稳打滑的问题，确保整套手调式标识摆角调节装置在运行期间，始终保持良好的动力传递性能和顺畅准确的调角功能。
作为上述调角旋钮中继连接装置的一种优选结构，在上述调角旋钮轴身制有对称形状凹槽和非对称形状凹槽，在对称形状凹槽轴身制有通孔，在上述双向连接块筒体制有对称形状凸条和非对称形状凸条，在对称形状凸条对应通孔位置制有倒扣凸块，中继安装时，倒扣凸块插入通孔成倒扣凸块—通孔卡持接触。通过在调角旋钮与双向连接块之间增设了 倒扣凸块—通孔卡持接触组合结构，这样，到电风扇厂总装流水线中继安装时，可以把调角旋钮轴身通孔穿过电机罩壳，以唯一到位位置方式，准确可靠地插装在双向连接块的倒扣凸块上成卡持式中继连接；另一方面，也可以解决调角旋钮中继安装完出厂后，在运输中以及在使用者来回扭动调角旋钮的日常使用中，常会出现返松滑脱掉出调角旋钮的顺插入式结构设置不良问题，从而组成一组既能符合电风扇业内安规行规相关规程，又能保障在日常使用中调角旋钮不会返松脱出的电风扇手调式标识摆角调节装置。
作为上述调角旋钮中继连接装置优选结构的进一步改进，上述非对称形状凹槽是沿对称形状凹槽的周向相互错开一个角度的非对称形状凹槽，其中一条为方形凹槽，另一条为圆弧形凹槽，上述非对称形状凸条是沿对称形状凸条的周向相互错开一个角度的非对称形状凸条，其中一条为方形凸条，另一条为第二圆弧形凸条，非对称形状的方形凸条和第二圆弧形凸条的纵向长度比对称形状凸条的纵向长度长。由于设置了非对称形状的方形凸条和第二圆弧形凸条的纵向长度相比对称形状凸条的纵向长度长出一段，因而在中继插装调角旋钮过程中，装配工人首先把调角旋钮轴身的非对称形状方形凹槽和圆弧形凹槽，以唯一对位方向且第一到位优先导入方式，插入到双向连接块筒体相对长度较长出一段的非对称形状方形凸条和第二圆弧形凸条上，而后在后续压入进程中，再把对称形状凹槽通孔，以第二到位方式，压入至双向连接块筒体长度较短的对称形状凸条的倒扣凸块，致其塑性回弹，插入通孔成倒扣凸块—通孔卡持接触，实践証明，这种双向连接块采用非对称凸条长度相对较长，保障第一到位优先的中继安装方式，可避免双向连接块倒扣凸块的弹性变形插装容易射偏缺点，明显提高了调角旋钮的唯一性中继安装效率，进一步兼容电风扇业内安装操作规程。

具体实施方式
下面结合图1至图7详细描述本发明的实施例。
本发明涉及一种电风扇手调式标识摆角调节装置。
电风扇的其它构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述，以下将对电风扇手调式标识摆角调节装置的结构展开描述。
参见图1至图6，本发明的电风扇手调式标识摆角调节装置，包括电机罩壳3，标识盘1，调角旋钮2，制有蜗轴套33和下轴套19的壳体9，制有上轴套7的壳盖8和二级减速机构，第二级减速机构有蜗轴齿轮31和大齿轮10，大齿轮10设有第一内腔12，第一内腔12置有由第一限位滑槽11—滑块17齿条18曲柄14与中心齿轮13组成的曲柄调节机构，标识盘1置有分级标识的每级标识角位移角度，与中心齿轮13的每齿角位移角度相等，空心轴6，中心轴5，在空心轴6上端制有圆形迭级台阶20与标识盘1之间置有一组具唯一性定位连接的标识盘中继连接装置，在中心轴5与调角旋钮2之间置有一组具唯一性定位连接的调角旋钮中继连接装置，该调角旋钮中继连接装置由双向连接块4以打螺钉21固装于中心轴上端构成，大齿轮10下端有限位盖15，限位该15制有第二限位滑槽16，曲柄14穿过第二限位滑槽16至大齿轮10外，在标识盘1与调角旋钮2之间置有限位槽22—限位块23机构，限位槽22—限位块23机构是在标识盘1制有圆弧形限位槽22，在调角旋钮2制有限位块23，限位块23插入限位槽22内，限位槽22的既定限位行程等于标识盘1既定标识的有效限位行程。
通过在标识盘1与调角旋钮2之间增设一组限位槽22—限位块23机构，组成的有既定限位行程的内限式阻挡机构，替代现有技术中调角旋钮与大圆轮之间的全旋无阻挡机构，调角中，一旦使用者扭动调角旋钮2力量过大或误操作方向相反，致中心轴5下端的中心齿轮13与滑块17齿条18将要碰到第一限位滑槽11限位端阻挡面时，扭力输入端调角旋钮2的限位块23首先把调角旋钮2牢固阻挡在标识盘1限位槽22的既定限位端面，使调角旋钮2止动，同步制止了中心轴5与空心轴6下端中心齿轮13与滑块17齿条18的过冲动作位移，从而在结构设置上彻底消除了中心齿轮13与滑块17齿条18因手扭动调角旋钮2力量过大或误操作所造成的扫齿现象。
参见图2，图3，图4，图5和图10，在滑块17制有第二内腔28，第二内腔28内壁制有齿条18，中心齿轮13插入第二内腔28与齿条18啮合，在滑块17外壁制有分级凹凸体26，分级凹凸体26中心距与齿条18齿距相等，分级凹凸体26顶端与第一限位滑槽11槽壁成滑配合，在第一限位滑槽11槽壁制有缺口30，在大齿轮10第一内腔12置有弹簧24—第一圆弧形凸条25紧定物装置的第一圆弧形凸条25紧定物穿过缺口30与分级凹凸体26成弹性紧定接触。
通过在滑块17外壁增加制有一排中心距与齿条18齿距相等的分级凹凸体26，在第一限位滑槽11的常规槽壁中段破开制有缺口30，并在缺口30位置增设一套弹性紧定物装置，以弹性紧定接触方式顶压分级凹凸体26，于是，限定了滑块17齿条18曲柄14只能按分级凹凸体26的置定中心距，在第一限位滑槽11中，作置定与位移，从而组成一组带分级凹凸体26限定位移轨迹的滑块17齿条18往复式曲柄14变长调节机构，由于分级凹凸体26中心距与滑块17齿条18齿距相等，滑块17齿条18齿距与中心齿轮13齿距相等，中心齿轮13每齿角位移角度与标识盘1每级分级标识角位移角度相等，这样，就组成一套能按标识盘既定分级标识，准确等量地调节滑块17齿条18曲柄14偏心距实际位移长度的电风扇手调式标识摆角调节装置，具有结构紧凑合理，符合电风扇制造业安规行规的优点。
在滑块17下端面与曲柄14之间制有迭级凸块27，在限位盖15沿第二限位滑槽16制有延伸滑槽29，迭级凸块27置入延伸滑槽29成滑配合，限位盖15装在大齿轮10上将第一内腔12封闭。通过在滑块17下端面与曲柄14之间增设迭级凸块27，在限位盖15沿第二限位滑槽16增设延伸滑槽29，把迭级凸块27置入延伸滑槽29成滑配合，这样，在滑块17齿条18曲柄14变长调节机构中，形成了由第一限位滑槽11—滑块17和延伸滑 槽29—迭级凸块27组成的单滑块17双平面双滑槽直线导向滑配合架构，增强了曲柄14的滑配合垂直稳定性，减少了调角时中心齿轮13的横向扭力影响，并提高了曲柄14抵御外力冲撞的抗冲击力，能更可靠地保护齿条18和中心齿轮13即使在曲柄14遇到超荷外力冲击下，也不会产生扫齿现象。
参见图2，图3，图6，图9和图10，在壳体9蜗轴套33下段壁内沿蜗轴齿轮31的齿顶圆面非啮合部分制有圆弧加强套32，圆弧加强套32的圆弧面与蜗轴齿轮31相对应的齿顶圆面呈动配合状态。这样一来，增强了蜗轴齿轮31与大齿轮10的啮合稳定性，解决了因蜗轴齿轮31远端呈单端悬臂状与大齿轮10啮合存在稳定性偏低，在手扭调角过程中易产生啮合失稳打滑的问题，确保整套手调式标识摆角调节装置在运行期间，始终保持良好的动力传递性能和顺畅准确的调角功能。
参见图2，图3，图4，图7和图8，在调角旋钮2中继连接装置中，调角旋钮2轴身制有对称形状凹槽36和非对称形状凹槽，在对称形状凹槽36轴身制有通孔34，在上述双向连接块4筒体制有对称形状凸条39和非对称形状凸条，在对称形状凸条39对应通孔位置制有倒扣凸块35，中继安装时，倒扣凸块35插入通孔34成倒扣凸块35—通孔34卡持接触。通过在调角旋钮与双向连接块之间增设了倒扣凸块35—通孔34卡持接触组合结构，这样，到电风扇厂总装流水线中继安装时，可以把调角旋钮2轴身通孔34穿过电机罩壳3，以唯一到位位置方式，准确可靠地插装在双向连接块4的倒扣凸块35上成卡持式中继连接；另一方面，也可以解决调角旋钮中继安装完出厂后，在运输中以及在使用者来回扭动调角旋钮的日常使用中，常会出现返松滑脱掉出调角旋钮的顺插入式结构设置不良问题，从而组成一组既能符合电风扇业内安规行规相关规程，又能保障在日常使用中调角旋钮2不会返松脱出的电风扇手调式标识摆角调节装置。
上述非对称形状凹槽是沿对称形状凹槽36的周向相互错开90度的非对称形状凹槽，其中一条为方形凹槽37，另一条为圆弧形凹槽38，上述非对称形状凸条是沿对称形状凸条39的周向相互错开90度的非对称形状凸条，其中一条为方形凸条40，另一条为第二圆弧形凸条41，非对称形状的方形凸条40和第二圆弧形凸条41的纵向长度比对称形状凸条39的纵向长度长。由于设置了非对称形状的方形凸条40和第二圆弧形凸条41的纵向长度相比对称形状凸条39的纵向长度向上长出一段，因而在中继插装调角旋钮2过程中，装配工人首先把调角旋钮2轴身的非对称形状方形凹槽37和圆弧形凹槽38，以唯一对位方向且第一到位优先导入方式，插入到双向连接块4筒体相对长度较长出一段的非对称形状方形凸 条40和第二圆弧形凸条41上，而后在后续压入进程中，再把对称形状凹槽36通孔34，以第二到位方式，压入至双向连接块4筒体长度较短的对称形状凸条39的倒扣凸块35，致其塑性回弹，插入通孔34成倒扣凸块35—通孔34卡持接触，实践証明，这种双向连接块4采用非对称凸条长度相对较长，应用于唯一定位且保障第一到位优先导入的中继安装方式，可避免双向连接块4倒扣凸块35的弹性变形插装容易射偏缺点，明显提高了调角旋钮2的唯一性中继安装效率，进一步兼容电风扇业内安装操作规程。
综上所述，本发明提出的电风扇手调式标识摆角调节装置，其有益意义在于：
1.在标识盘1与调角旋钮2之间增设一组限位槽22—限位块23机构，使用者操作时，消除了扫齿现象；
2.通过对滑块17构件优化设计，集成了第二内腔28内壁齿条18外壁分级凹凸体26迭级凸块27曲柄14等机械构件元素，一体化构成一个机械式MCU元件，既可执行按标识盘1均值标识等量输入预置值，又可驱动齿条18曲柄14偏心距按预置值作等量位移，还可在曲柄14调角后按既定内存数据等量反馈出采样值的三位一体MCU构件功能，解决了按标识盘1均值标识等量输入，等量驱动，等量控制的手调操作三等量要求，很好地实现按标识盘1标识准确等量调角的目的；
3.成本上，集成了滑块17第二内腔28内壁齿条18外壁分级凹凸体26迭级凸块27曲柄14等多功能构件，一体化生产为单一元件，优化了第一限位滑槽11缺口30和弹簧24—第一圆弧形凸条25组合架构，取消了轴位铆钉并简化了装配工艺，降低了工料成本，实现了按标识盘1标识准确等量调角总体成本性价比最优。
4.日常使用上，在调角旋钮2与双向连接块4之间增设倒扣凸块35—通孔34卡持接触组合机构，很好地解决了电风扇调角旋钮2在日常使用中不会出现返松脱出的问题。
当然，本发明电风扇手调式标识摆角调节装置中，在分级凹凸体与大齿轮内腔之间置有弹簧—紧定物装置所述的紧定物的具体形状，不局限于上述实施例所示的第一圆弧形凸条，也可以是其它适配形状的紧定物，这样的紧定物具体形状的局部变换，均落在本发明保护范围内；显然，上述的实施例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作出创造性劳动前提下获得的所有其它实施例，都属于本发明保护的范围。
