具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图16详细描述根据本发明实施例的箱式风扇1。
如图1-图16所示，根据本发明实施例的箱式风扇1包括：壳体100和扇叶(图未示出)。所述扇叶可转动地设在壳体100内，换言之，壳体100将所述扇叶罩设在其内部，不仅可以利用壳体100对所述扇叶进行保护，而且可以避免用户接触到转动的所述扇叶而对用户造成伤害。
具体而言，参照图2，壳体100包括两个面罩(例如图2中所示的第一面罩111和第二面罩112)和外框(例如图2中所示的第一侧板121、第二侧板122、第三侧板123以及第四侧板124围成)，两个所述面罩相对且间隔开设置(例如图2中所示的第一面罩111和第二面罩112在前后方向上间隔开且相对设置)，所述外框设在两个所述面罩之间，所述外框与两个所述面罩分别通过自身的结构拼接安装且至少一个所述面罩相对于所述外框可推拉地拆装，换言之，两个所述面罩分别与所述外框拼接安装，并且两个所述面罩中的一个相对于所述外框可推拉地拆装或两个所述面罩均相对于所述外框可推拉地拆装。例如，在图3所示的示例中，参照安装步骤S4，示出了一个所述面罩与所述外框采用可推拉的方式拼 接安装的实施例。
这里需要理解的是，两个部件之间“通过自身的结构拼接安装”可以理解为：两个部件通过各自本身具备的结构实现连接，从而使得这两个部件达到牢靠连接的效果。
两个部件之间“可推拉地拆装”指的是：通过推拉的动作实现拆装，换言之，拼接安装的过程需要伴随推拉动作。这样在装配所述外框和所述面罩的过程中，可以使所述外框静止、推拉所述面罩实现拼接安装，或者可以使所述面罩静止，推拉所述外框实现拼接安装。
根据本发明实施例的箱式风扇1，由于两个所述面罩与所述外框均通过拼接方式安装，相比相关技术中通过螺钉连接面罩和外框的方式，大幅减少了螺钉的数量，不仅可以减少安装螺钉的工序，从而简化了壳体100的装配工序，提高了壳体100的装配效率，而且可以省去大量螺钉的材料和制造成本，从而降低了箱式风扇1的生产成本。
并且，由于至少一个所述面罩相对于所述外框可推拉地拆装，这样在安装或拆卸所述面罩时，可以通过推拉所述面罩或所述外框实现所述面罩的拆装，不仅可以在安装时便于所述面罩和所述外框之间进行对位，以便于将所述面罩安装在所述外框上，从而提高箱式风扇1的生产效率，而且可以减小所述外框和所述外框之间的缝隙，使箱式风扇1的外形更加整齐美观。
因此，根据本发明实施例的箱式风扇1可以简化壳体的装配工序，提高壳体的装配效率，减少了用于装配壳体的零部件，降低了生产成本。
下面参考附图描述根据本发明具体实施例的箱式风扇1。
可选地，两个所述面罩和所述外框可以均为塑料件。该塑料件可以由PT、PET(聚对苯二甲酸乙二醇酯)、PBT(聚对苯二甲酸丁二醇酯)、PP(高聚物聚丙烯)、ABS(丙烯腈-丁二烯-苯乙烯共聚物)等制成。具体而言，两个所述面罩和所述外框均为注塑件。这样不仅可以简化两个所述面罩和所述外框的制造工艺，便于两个所述面罩和所述外框的制造，而且可以便于两个所述面罩和所述外框上用于拼接安装的结构的形成，以提高两个所述面罩和所述外框的生产效率。
具体地，所述至少一个面罩与所述外框卡扣连接和/或插接配合。换言之，两个所述面罩中相对于所述外框可推拉拆装的一个或两个可以采用卡扣连接和/或插接配合的方式实现与外框的拼接安装。由此，通过简单的结构就可以实现拼接安装，从而降低所述面罩和所述外框的加工难度，降低生产成本，提高生产效率。
在本发明的一个实施例中，所述外框包括首尾顺次拼接安装的多个侧板。换言之，所述外框由多个所述侧板构成，多个所述侧板首尾相连环绕一圈，其中相邻的两个所述侧板拼接安装。由此可以简化每个所述侧板的结构，降低所述外框的加工和制造难度，从而节 约了生产周期，降低了生产成本。
可选地，相邻的两个所述侧板均卡扣连接和/或插接配合。优选采用卡扣连接和插接配合的方式拼接安装(例如通过图4、图5、图8和图9中所示的第二卡扣160b和第二卡孔150b的卡扣连接以及插接块130和插接槽140的插接配合)。由此不但可以增加相邻所述侧板连接结构的多样性，以提高相邻两个所述侧板的连接强度和稳定性。
下面，参照图1-图10，描述根据本发明一个具体实施例的壳体100。
参照图1和图2，两个所述面罩分别为相对设置的第一面罩111和第二面罩112，第一面罩111和第二面罩112可以均构造成矩形，所述外框可以包括首尾顺次卡扣连接的第一侧板121、第二侧板122、第三侧板123和第四侧板124，第一侧板121与第三侧板123相对设置且分别与第一面罩111相对的两边沿配合，第二侧板122与第四侧板124相对设置且分别与第一面罩111相对两边沿配合，第二面罩112相对于所述外框可推拉且分别与第一侧板121、第二侧板122和第三侧板123配合。
具体而言，第一面罩111和第二面罩112可以平行设置，第一侧板121与第三侧板123平行设置且分别与第一面罩111相对的两边沿卡扣连接，第二侧板122与第四侧板124平行设置且分别与第一面罩111相对两边沿卡扣连接，第二面罩112相对于所述外框可推拉且分别与第一侧板121、第二侧板122和第三侧板123卡扣连接。例如，第二面罩112可以推拉安装到位后通过第一侧板121、第二侧板122和第三侧板123上的卡扣进一步进行限位。其中，第二面罩112位于第一面罩111前方，即第二面罩112为前面罩且第一面罩111为后面罩，第二面罩112上安装有扇叶电机200，所述扇叶安装在扇叶电机200上以在扇叶电机200的驱动下旋转。
这里需要理解地是，包括弧形过渡的结构也应理解为是本发明的矩形，例如附图中示出的第一面罩111和第二面罩112，两个面罩的拐角处均圆弧过度。
换言之，第一面罩111与第二面罩112均构造成矩形且相互平行，第一侧板121至第四侧板124首尾顺次连接成一个矩形，每相对的两所述侧板相互平行且分别与第一面罩111相对两边沿拼接安装，且相邻的两个所述侧板之间通过卡扣拼接安装，第二面罩112分别与第一侧板121至第三侧板123卡扣连接且相对于所述外框可推拉。由此便于所述外框的加工和以及壳体100的装配，从而可以提高箱式风扇1的生产效率。
具体而言，每个所述侧板与第一面罩111的卡扣连接方式均可以相同，下面仅以第四侧板124与第一面罩111的卡扣连接方式为例进行说明。参照图4，第四侧板124与第一面罩111连接的部位可以设有多个第一卡扣160a，第一面罩111与第四侧板124连接的部位可以设有多个第一卡孔150a，多个第一卡扣160a适于与多个第一卡孔150a一一对应卡扣连接，从而实现第四侧板124与第一面罩111的插接相连。同理，第一侧板121、第三 侧板123、第四侧板124与第一面罩111也可以通过自身的第一卡扣160a和第一卡孔150a实现卡扣拼接安装。
相邻的两个所述侧板的连接方式也可以均相同，下面仅以第一侧板121与第四侧板124的卡扣连接方式为例进行说明。优选地，第一侧板121和第三侧板123的二端分别形成有突出的卡扣结构，而第二侧板122和第四侧板124的二端分别形成有凹陷的卡孔结构。
参照图4、图5、图8和图9，第一侧板121的与第四侧板124拼接安装的一端(如图8中所示的第一侧板121的下端)设有多个第二卡扣160b，第四侧板124的与第一侧板121拼接安装的一端(如图8所示的第四侧板124的左端)设有多个与第一侧板121上的第二卡扣160b一一对应连接的第二卡孔150b，从而实现第一侧板121与第四侧板124的拼接安装。同理，第一侧板121、第二侧板122、第三侧板123和第四侧板124之间的相互连接也可以分别通过自身的第二卡扣160b和第二卡孔150b实现拼接安装。
当然，本发明不限于此，在本发明的其它实施例中，第一侧板121、第二侧板122、第三侧板123以及第四侧板124还可以构造成其他形状，例如，第一侧板121和第二侧板122为直板，第三侧板123和第四侧板124可以为U行板。具体而言，第一面罩111下端的两个拐角处分别由第四侧板124的两端包裹且上端的两个拐角处分别由第二侧板122的两端包裹，第二面罩112的下端的两个拐角处分别由第四侧板124的两端包裹且上端的两个拐角处分别由第二侧板122的两端包裹。
有利地，参照图6和图9，第一侧板121至第四侧板124上分别形成有限位槽125，第一面罩111的四个边沿分别插接配合在相应的限位槽125内。由此，当预先使所述侧板与第一面罩111插接配合装配完成后，可以顺利地实现卡扣连接的动作，从而方便且快速地实现所述侧板与第一面罩111的装配，且可以增加第一侧板121至第四侧板124与第一面罩111的连接的可靠性，避免第一面罩111与侧板的连接处出现缝隙，并利用第一侧板121至第四侧板124包括第一面罩111的边沿和拐角，确保壳体100的外观美观。
其中，第一侧板121和第三侧板123上的限位槽125分别为宽度沿由第二侧板122至第四侧板124的方向逐渐增大的楔形槽。这里需要理解的是，“限位槽125的宽度”指限位槽125沿长度方向定向的相对两侧壁之间的距离。这样在装配时，在推动第一侧板121和第三侧板123的过程中，方便第一面罩111的边沿进入第一侧板121和第三侧板123上的限位槽125，且随着第一侧板121和第三侧板123的推入，第一面罩111的边沿与第一侧板121和第三侧板123上的限位槽125的配合逐渐变紧，从而提高第一面罩111与第一侧板121和第三侧板123拼装后的可靠性。
更为有利地，第一侧板121、第二侧板122、第三侧板123和第四侧板124中相邻的两个通过插接块130和插接槽140插接配合。具体而言，相邻的两个所述侧板之间的插接配 合方式均可以相同，下面仅以第一侧板121与第四侧板124的插接配合方式为例进行说明。例如在图4、图5、图8和图9的示例中，第一侧板121的与第四侧板124拼接安装的一端(如图8中所示的第一侧板121的下端)设有多个插接块130，第四侧板124的与第一侧板121拼接安装的一端(如图8所示的第四侧板124的左端)设有多个与第一侧板121上的插接块130一一对应连接的插接槽140，从而实现第一侧板121与第二侧板122的拼接安装。由此，当插接块130与插接槽140插接到位后，第二卡扣160b与第二卡孔150b可以顺势卡扣配合，从而提高了装配效率。另外，插接块130与插接槽140的加工简便、方便实现。同理，第一侧板121、第二侧板122、第三侧板123和第四侧板124之间的相互连接也可以通过插接块130和插接槽140的方式实现拼接安装。
可选地，参照图13，第一侧板121、第二侧板122、第三侧板123上分别形成有推拉槽126，第二面罩112与推拉槽126可推拉地配合。由此，通过推拉第二面罩112可以使第二面罩112能够穿过推拉口127，并配合在第一侧板121至第三侧板123的推拉槽126内，实现第二面罩112与三个所述侧板的拼接安装，从而有效地提高了装配效率。
具体而言，第四侧板124上形成有推拉口127，第二面罩112通过推拉口127与推拉槽126可推拉地配合。例如，在如图13所示的示例中，第一侧板121、第二侧板122以及第三侧板123上分别形成有沿其长度方向延伸的推拉槽126，第四侧板124上形成有沿其长度方向延伸的推拉口127，当第二面罩112穿过推拉口127后，可以沿着第一侧板121和第三侧板123上的推拉槽126朝向第二侧板122的方向推动、直至第二面罩112的一边沿配合在第二侧板122上的推拉槽126内，从而完成第二面罩112与外框的可推拉拼接安装。另外，由于第一面罩111是矩形的，且第一侧板121、第二侧板122、第三侧板123以及第四侧板124首尾顺次连接成矩形形状，可以使第二面罩112的两侧边(如图13所示的第二面罩112的左右两侧边)可以与第一侧板121和第三侧板123的推拉槽126一直接触，从而更加方便实现推拉配合动作，提高了装配效率。此外，可以利用第一侧板121至第三侧板123包括第二面罩112的边沿和拐角。
其中，第一侧板121和第三侧板123上的推拉槽126分别为宽度沿由第二侧板122至第四侧板124的方向逐渐增大的楔形槽。这里需要理解的是，“推拉槽126的宽度”指推拉槽126沿长度方向定向的相对两侧壁之间的距离。这样在装配时，在推动第二面罩112的过程中，方便第二面罩112的边沿进入第一侧板121和第三侧板123上的推拉槽126，且随着第二面罩112的推入，第二面罩112的边沿与第一侧板121和第三侧板123上的推拉槽126的配合逐渐变紧，从而提高第二面罩112与第一侧板121和第三侧板123拼装后的可靠性。
当然，本发明不限于此，第一侧板121至第四侧板124中的任意三个侧板上可以形成 有推拉槽126，其余一个侧板上可以形成有推拉口127，以实现第二面罩112的推拉式安装。
具体地，第三侧板123的远离第一面罩111的侧表面(如图13中所示的第三侧板123的前表面123a)和第一侧板121的远离第一面罩111的侧表面(如图13中所示的第一侧板121的前表面121a)均高于第四侧板124的远离第一面罩111的侧表面(如图13中所示的第四侧板124的前表面124a)，推拉口127由第四侧板124的所述侧表面与第一侧板121和第三侧板123共同限定出，推拉口127与第二面罩112的其中一个边沿配合。由此，可以便于推拉口127的形成，简化所述外框的结构及加工工序，节约所述外框的生产周期，降低所述外框的生产成本。
简言之，在成型时，使第四侧板124的高度低于第一侧板121和第三侧板123，就可以自然得到推拉口127。
当然，本发明不限于此，推拉口127还可以是贯穿第四侧板124的一个长矩形口且与第四侧板124的前表面间隔开(图未示出该示例)。
进一步地，第二面罩112与第一侧板121至第三侧板123分别卡扣连接，这样，当第二面罩112与三个侧板插接配合的插接相连后，还可以进一步通过卡扣拼接安装的方式实现更加牢靠地拼接安装，从而可以有效地增加第二面罩112与第一侧板121至第三侧板123之间连接的可靠性。例如，在如图13所示的示例中，第一侧板121至第三侧板123与第二面罩112连接的部位设有多个第一卡扣160a(这里需要理解的是，多个第一卡扣160a分别邻近第一侧板121至第三侧板123的前端和后端设置，图中未示出邻近第一侧板121至第三侧板123的前端的多个第一卡扣160a)，第二面罩112上设有与第一侧板121至第三侧板123的第一卡扣160a一一对应连接的第一卡孔150a，多个第一卡扣160a和多个第一卡孔150a分别一一对应卡扣相连，从而实现第二面罩112与第一侧板121至第三侧板123的卡扣连接。这样在第二面罩112通过推拉插接安装到位后，可以使第一卡扣160a卡合在第一卡孔150a内以进一步对第二面罩112进行定位，从而提高第二面罩112安装后的稳定性。
其中，参照图13和图15，第二面罩112的邻近第四侧板122的边沿(如图13所示的第二面罩112的下边沿)上设有用于封挡在推拉口127外侧的装饰边128，当第二面罩112与外框拼接安装到位后，装饰边128恰好封挡推拉口127且与第四侧板124的外表面平齐。由此可以避免第二面罩112与第四侧板124之间出现缝隙而影响美观，同时提高了对扇叶的保护效果。防止灰尘通过推拉口127进入壳体100内部，从而保持箱式风扇内部的清洁。
需要说明的是，上述描述中的第一卡扣160a、第二卡扣160b、第一卡孔150a、第二卡孔150b、插接块130和插接槽140的形状和个数不作限制，只要能满足第一侧板121至第四侧板124与第一面罩111和第二面罩112的安装即可。
根据本发明实施例的箱式风扇1，实现了用全塑胶材料替代五金材料，可以大大降低材 料成本、加工成本，提高了箱式风扇的可制造性，卡扣式连接方案大幅减少了所需螺钉的数量，从而降低生产成本、提高生产效率。采用拼接式结构塑料边框可以增加整机外观的多样性，能够满足日益变化的市场需求。
根据本发明实施例的箱式风扇1的其他构成例如控制开关170等以及其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。
下面描述根据本发明实施例的用于箱式风扇的壳体100。
根据本发明实施例的用于箱式风扇的壳体100包括第一面罩111和第二面罩112和外框。第一面罩111和第二面罩112均构造成矩形，第一面罩111和第二面罩112相对且间隔开设置。所述外框设在第一面罩111和第二面罩112之间且包括沿所述外框的周向首尾顺次拼接安装的第一侧板121至第四侧板124，第一侧板121与第三侧板123相对设置且分别与第一面罩111相对两边沿拼接安装，第二侧板122与第四侧板124相对设置且分别与第一面罩111另外相对两边沿拼接安装，第二面罩112相对于所述外框可推拉且分别与第一侧板121至第三侧板123配合。
根据本发明实施例的用于箱式风扇的壳体，具有装配工序简单、装配效率高、成本低等优点。
下面参考图1-图17描述根据本发明实施例的箱式风扇的的装配方法，以所述箱式风扇为根据本发明上述实施例的箱式风扇1为例，箱式风扇1包括第一面罩111、第二面罩112、外框和扇叶电机200，所述装配方法包括先后顺序可调换的两个步骤：
将扇叶电机200安装在第一面罩111上；
将外框通过其自身的结构和第一面罩111自身的结构拼接安装在第一面罩111上；
也就是说，可以先将扇叶电机200安装在第一面罩111上，再将外框拼接安装在第一面罩111上。也可以先外框拼接安装在第一面罩111上，再将扇叶电机200安装在第一面罩111上。
所述装配方法还包括在上述两个步骤之后的步骤：
采用推拉的方式将第二面罩112通过其自身的结构和外框自身的结构拼接安装在外框上。
根据本发明实施例的箱式风扇的装配方法，简化了箱式风扇的装配工序，提高了箱式风扇的装配效率，而且可以大幅减少螺钉的用量，从而减少材料成本，进而降低箱式风扇的生产成本。
并且，采用推拉的方式安装第二面罩，不仅可以在安装时便于所述面罩和所述外框之间进行对位，以便于将所述面罩安装在所述外框上，从而提高箱式风扇的生产效率，而且可以减小所述外框和所述外框之间的缝隙，使箱式风扇的外形更加整齐美观。
在本发明的一个实施例中，所述外框由多个侧板构成，装配时，将多个所述侧板分别拼接安装在第一面罩111上，且将多个所述侧板首尾拼接，使多个侧板在第一罩面111上构成外框，从而进一步方便外框与第一面罩111的装配。
具体而言，以外框由第一侧板121、第二侧板122、第三侧板123和第四侧板124构成为例，描述将外框装配的方法。
将第四侧板124拼接安装在第一面罩111上；
将第一侧板121和第三侧板123拼接安装在第一面罩111上且分别与第四侧板124拼接安装；
将第二侧板122拼接安装在第一面罩111上且分别与第一侧板121和第三侧板123拼接安装；
将第二面罩112从第四侧板124处推向第一侧板121、第二侧板122和第三侧板123之间且分别与第一侧板121、第二侧板122和第三侧板123拼接安装。
具体地，如图4所示，第四侧板124通过在第一面罩111所在的平面内沿朝向第一面罩111的方向推进而拼接安装在第一面罩111上。
第一侧板121和第三侧板123分别通过在第一面罩111所在的平面内沿朝向第四侧板124的方向推进而拼接安装在第一面罩111和第四侧板124。
第二侧板122通过在第一面罩111所在的平面内沿朝向第四侧板124的方向推进而拼接安装在第一面罩111以及第一侧板121和第三侧板123上。这样可以进一步简化壳体100的装配工序，降低装配人员的劳动强度。
这里需要理解的是，第一面罩111所在平面指第一面罩111的最大面积的平面所在的平面，例如图中垂直于前后方向的平面。
当然，外框也可以由其他数量的侧板构成，例如外框由两个侧板构成，装配时分别将两个侧板拼装在第一面罩111上且使两个侧板彼此拼装，以构成外框。
下面参考图3，并结合图4-图16简要描述根据本发明一个具体实施例的壳体100的装配过程。下述描述只是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
