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，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。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所获得的所有其他实施例，都属于本发明保护的范围。
为了解决现有技术中的风扇的结构复杂，导致风扇的装配效率低，且现有的风扇无法实现导风轮的可靠止转，导致风扇的实用性差的问题，本发明提供了一种风扇。
本申请提供了三个实施例，图1至图11示出的为实施例一，图12至图18示出的为实施例二，图19至图25示出的为实施例三。
实施例一
如图1所示，风扇包括外壳组件10、导风轮组件20和抵推件30，导风轮组件20可枢转地设置在外壳组件10上；其中，导风轮组件20具有安装孔221，外壳组件10具有止转结构，止转结构伸入安装孔221内，止转结构具有避让空间；，抵推件30可枢转地设置在外壳组件10上，抵推件30转动时，抵推件30的抵推端伸入避让空间并抵推止转结构，止转结构发生形变并与安装孔221的孔壁抵接，而使导风轮组件20停止转动。
在本申请中，将导风轮组件20安装在外壳组件10上，外壳组件10具有止转结构，利用抵推件30与止转结构配合，实现导风轮组件20的转动或可靠止转。具体来说，抵推件30的抵推端伸入避让空间并抵推止转结构，止转结构发生形变并与导风轮组件20的安装孔221的孔壁抵接，而使导风轮组件20停止转动；抵推件30的抵推端由避让空间退出，导风轮组件20可以相对于外壳组件10转动。此外，本申请的外壳组件10具有止转结构，仅需要将导风轮组件20装配在外壳组件10上，简化了风扇的结构，提升了风扇的装配效率。
本申请提供的风扇采用风力带动的方式带动导风轮组件20转动，与利用电机带动导风轮组件20转动的方式相比，降低了风扇的耗电功率，从而降低了风扇的使用成本。
如图1、图6和图7所示，导风轮组件20包括导风轮21和轴套22，导风轮21与轴套22固定连接，轴套22具有安装孔221，导风轮21通过轴套22与外壳组件10连接。考虑到导风 轮组件20在使用中与止转结构配合出现的磨损，将导风轮组件20拆分设计为不同材料制成的导风轮21和轴套22，其中，轴套22由耐磨的材料制成。
在本申请的一个未图示的实施例中，轴套22和导风轮21一体成型。
如图6至图9所示，导风轮21上开设有至少一个卡接孔211，轴套22包括轴套本体222和设置在轴套本体222上的至少一个连接卡扣223，连接卡扣223穿设在卡接孔211内，并与卡接孔211内的台阶结构卡接。这样，导风轮21和轴套22卡接连接，从而不需要设置螺钉等额外的零件，能够提升风扇的装配效率，还能够避免风扇装配过程中出现螺钉丢失的情况。导风轮21与轴套22卡接连接后，能够防止导风轮21和轴套22之间发生轴向的相对窜动，即导风轮21和轴套22之间为相对静止状态。
如图9所示，安装孔221形成在轴套本体222上，连接卡扣223为多个，多个连接卡扣223绕安装孔221的周向间隔设。通过设置多个连接卡扣223，从而提升导风轮21和轴套22的连接稳定性。
如图8和图9所示，导风轮21上开设有装配孔212，装配孔212的孔壁上开设有至少一个止转缺口213，轴套22还包括设置在轴套本体222上的至少一个止转凸起224，止转凸起224伸入至止转缺口213内。这样，导风轮21和轴套22装配后，防止导风轮21和轴套22之间发生相对转动，导风轮21和轴套22同步转动或同步止转。
如图2、图3和图10所示，外壳组件10包括前壳11，前壳11包括前壳本体111、连接筒112和多个安装卡扣113，连接筒112设置在前壳本体111上，多个安装卡扣113设置在前壳本体111上，并绕连接筒112的外周侧间隔设置，安装卡扣113穿过安装孔221后与轴套22卡接。这样，前壳11与轴套22卡接，使导风轮21通过轴套22可转动地设置在前壳11上。在装配轴套22和前壳11时，不需要设置螺钉等额外的零件，能够进一步地提升风扇的装配效率，还能够避免风扇装配过程中出现螺钉丢失的情况。
如图4、图5和图10所示，前壳11还包括多个锁紧卡扣114，多个锁紧卡扣114设置在连接筒112的远离前壳本体111的端面上，并绕连接筒112的周向间隔设置，多个锁紧卡扣114形成止转结构，多个锁紧卡扣114围成避让空间。这样，抵推件30的抵推端抵推锁紧卡扣114，使锁紧卡扣114发生形变并与轴套22的安装孔221的孔壁抵接并发生干涉，从而阻止轴套22相对于前壳11转动，相应地，阻止与轴套22连接的导风轮21相对于前壳11转动，实现导风轮组件20的可靠止转，切换风扇的供风模式，提升风扇的实用性。
如图10所示，前壳11还包括多个限位块110，多个限位块110设置在前壳本体111上并绕连接筒112的周向设置，且限位块110位于两个安装卡扣113之间，限位块110的远离连接筒112的表面与轴套22的安装孔221的孔壁之间的配合间隙较小，从而避免轴套22相对于前壳11发生径向上的较大距离的窜动。
如图10和图11所示，连接筒112的内壁面上设置有第一螺纹结构115，抵推件30为帽盖，帽盖包括盖板31和设置在盖板31上的安装筒32，安装筒32的外周壁上沿远离盖板31 的方向依次设置有抵推凸起33和与第一螺纹结构115配合的第二螺纹结构321；抵推凸起33形成抵推端。在本申请的实施例一中，抵推件30与前壳11螺纹连接，通过控制抵推件30旋入的深度，控制导风轮组件20的转动或止转，当旋入至抵推凸起33与锁紧卡扣114接触并发生干涉的位置时，抵推凸起33抵推锁紧卡扣114使锁紧卡扣114发生形变。
如图11所示，抵推凸起33呈环形并绕安装筒32的外周壁连续设置。这样，能够保证抵推凸起33能够可靠稳定地抵推锁紧卡扣114。
应用实施例一提供的风扇，用户通过旋紧或旋松帽盖控制导风轮组件20是否转动，当帽盖向下旋紧到一定程度时，抵推凸起33抵推锁紧卡扣114，锁紧卡扣114与安装孔221的孔壁干涉形成锁紧关系，此时导风轮组件20停止转动；当帽盖向上旋松到一定程度，即抵推凸起33不与锁紧卡扣114接触或抵推凸起33对锁紧卡扣114的抵推距离小于锁紧卡扣114和安装孔221之间的间隙时，锁紧关系解除，导风轮组件20在风叶风力的带动下开始转动。
实施例二
如图12至图14所示，实施例二与实施例一相同，轴套22与导风轮21卡接，前壳11与轴套22卡接，在此不再赘述。
实施例二与实施例一的区别在于，抵推件30与前壳11卡接连接。具体来说，如图17和图18所示，前壳本体111的与连接筒112相对的位置处开设有滑槽116，抵推件30为帽盖，帽盖包括盖板31、安装筒32、限位卡扣34和抵推凸轮35，安装筒32设置在盖板31上，限位卡扣34设置在安装筒32的远离盖板31的端面上，限位卡扣34穿过滑槽116，以使抵推件30与前壳11卡接，抵推凸轮35设置在安装筒32的外周壁上，抵推凸轮35形成抵推端，如图15和图16所示，旋转抵推件30以使抵推凸轮35抵推锁紧卡扣114，使锁紧卡扣114发生形变并与安装孔221的孔壁抵接，而使导风轮组件20停止转动；继续转动抵推件30，抵推凸轮35运动至两个锁紧卡扣114之间而不再抵推锁紧卡扣114，从而使导风轮组件20相对于前壳11自由地转动。
在实施例二中，用户仅需要通过在水平方向上旋转抵推件30，便可以控制导风轮组件20的转动或稳定地止转，从而切换风扇的供风模式，提升风扇的实用性。
如图18所示，抵推凸轮35为多个，多个抵推凸轮35绕安装筒32的外周壁间隔设置。通过设置多个抵推凸轮35，与多个锁紧卡扣114一一对应配合。
应用实施例二提供的风扇，用户通过在水平方向上旋转帽盖控制导风轮组件20是否转动，当帽盖逆时针旋转到一定程度时，抵推凸轮35抵推锁紧卡扣114，锁紧卡扣114与安装孔221的孔壁干涉形成锁紧关系，此时导风轮组件20停止转动；当帽盖顺时针旋转到一定程度，即抵推凸轮35不与锁紧卡扣114接触或抵推凸轮35对锁紧卡扣114的抵推距离小于锁紧卡扣114和安装孔221之间的间隙，锁紧关系解除，导风轮组件20在风叶风力的带动下开始转动。
实施例三
实施例三与实施例一的区别在于，轴套22与前壳11不再卡接连接，而使通过压盖12与前壳11配合，将轴套22限位在压盖12的凸出外缘122和前壳11之间。具体来说，如图19至图25所示，外壳组件10包括前壳11和压盖12，前壳11上开设有至少一个旋槽117，压盖12包括压盖本体121和旋扣123，压盖本体121的轴向第一端具有凸出外缘122，旋扣123设置在压盖本体121的轴向第二端的端面上；压盖本体121穿过安装孔221后将轴套22限位在凸出外缘122和前壳11之间。
需要说明的是，本申请涉及的压盖本体121穿过安装孔221后将轴套22限位在凸出外缘122和前壳11之间，是指轴向限位，装配完成后轴套22能够相对于前壳11和压盖12自由地转动。
如图24所示，压盖本体121的轴向第二端的端面上开设有连接孔125，风扇还包括连接件，连接件穿设在连接孔125处，以将压盖12紧固在前壳11上。
可选地，连接件为螺钉，连接孔125为螺纹孔。
如图23所示，止转结构为多个弹扣124，多个弹扣124绕压盖本体121的周壁面间隔设置，多个弹扣124围成避让空间。
如图22和图25所示，前壳11上设置有连接柱118，连接柱118的外周壁上设置有第三螺纹结构119；抵推件30为帽盖，帽盖包括盖板31、安装筒32和抵推筒36，安装筒32设置在盖板31上，安装筒32的内壁面上设置有与第三螺纹结构119配合的第四螺纹结构322，抵推筒36设置在盖板31上，并套设在安装筒32的外周侧，抵推筒36形成抵推端。
这样，在装配风扇时，将导风轮组件20放在前壳11上，压盖12穿过轴套22的安装孔221后，通过旋扣123旋入旋槽117，再通过连接件将压盖12与前壳11固定连接，旋转抵推件30，使抵推件30的抵推筒36伸入压盖12内并抵推弹扣124，使弹扣124发生形变并与安装孔221的孔壁抵接，从而使导风轮组件20停止转动；反方向旋转抵推件30，使抵推筒36不再抵推弹扣124，从而使导风轮组件20能够相对于前壳11和压盖12自由地转动。
应用实施例三提供的风扇，用户通过旋紧或旋松帽盖控制导风轮组件20是否转动，当帽盖向下旋紧到一定程度时，抵推筒36抵推弹扣124，弹扣124与安装孔221的孔壁干涉形成锁紧关系，此时导风轮组件20停止转动；当帽盖向上旋松到一定程度，即抵推筒36不与弹扣124接触或抵推筒36对弹扣124的抵推距离小于弹扣124和安装孔221之间的间隙时，锁紧关系解除，导风轮组件20在风叶风力的带动下开始转动。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：本申请提供的风扇结构简单、零件较少，不需要电机带动导风轮组件20转动，而是采用风力带动，相比于相关技术中的风扇而言，装配效率更高，具体来说，实施例一和实施例二仅需要4个零件，实施例三仅需要5个零件，且实施例一和实施例二均不需要螺钉固定，而实施例三仅需要一个螺钉，从而能够提升风扇的装配效率，有效节省工时，降低人工成本，避免装配过程中出现螺钉丢失的情况，导风轮组件20能够平稳地转动或稳定地止转，从而使风扇具有较佳的导 风性能。本申请设计了一种新型的导风轮旋转调节结构，使得导风轮组件20转动更平稳，整机导风性能更佳。
