Description

出风角度能调整的塔式风扇 技术领域
本发明涉及工作流体是空气的泵送装置,特别是涉及用于通风的泵送装置,尤其涉及出风角度能调整的塔式风扇。
背景技术
塔式风扇，简称为塔扇，因其外形似塔状而得名。现有技术塔式风扇多数呈纵向柱状，内部大多采用贯流式风轮组件，即风轮为圆柱形的贯流风轮，该贯流风轮轴向尺寸远大于直径，风道出风口为细长形状，风轮纵向安装在塔式风扇内部；这种风扇结构的优点是外观时尚，纵向风道出风口长，再配合摇头机构可实现一定角度的送风，而且噪音也比普通风扇低很多；但是这种风扇的缺点在于，由于风道出风口呈细长状，在某一时刻或者摆头处于静止状态时，其所吹出的风的送风角度很小；给人直观感受到的是一股细小的风扫过，多人使用时体验不佳。

具体实施方式
下面结合各附图对本发明作进一步详细说明。
参见图1至图15,一种出风角度能调整的塔式风扇,包括机体组件1和风轮组件2；所述机体组件1又包括设有多处不同角度出风口111的前壳11、设有多处不同角度进风口121的后壳12、底座13、电机支架14和电机15，所述电机支架14固定在底座13上，所述电机15固定电机支架14上；从前壳11上可以看出，每一横排设置有好几个出风口111，从上到下每一竖排还设置有几十个出风口111，这样在前壳11上就有很多不同角度的出风口111；从后壳12上可以看出，每一横排设置有好几个进风口121，从上到下每一竖排还设置有几十个进风口121，这样在后壳12上就有很多不同角度的进风口121；所述前壳11和后壳12的下端分别设置在所述电机支架14上，并相互扣合在一起；所述电机15位于所述前壳11和后壳12形成的容腔下端；所述风轮组件2则包括风轮21、风轮轴承22和风轮轴承支架23，所述风轮轴承22设置在所述风轮轴承支架23上，所述风轮轴承支架23设置在所述前壳11和后壳12形成的容腔上端，一般地可以将风轮轴承支架23固定在前壳11内腔上端；所述风轮21的下端与所述电机15的转轴共轴线联结，所述风轮21上端的凸轴211插入所述风轮轴承22的内孔内，所述电机15工作后带动所述风轮21旋转；所述塔式风扇还包括对流入塔式风扇内之空气起导向作用的风道架3，以及能将所述风道架3转动从而使该风道架3所形成的内部风道之出风角度方向发生改变的转动机构4；所述风道架3能转动地位于所述电机15和风轮轴承支架23之间，并将所述风轮21套住；工作时，所述电机15带动所述风轮21旋转，使空气从所述后壳12的进风口121流入，经过所述风道架3所形成的内部风道，然后从所述前壳11的出风口111吹出，而通过所述转动机构4来调整所述风道架3所形成的内部风道之出风角度方向，达到调整流入塔式风扇内空气的流动方向，使得流入塔式风扇内的空气能够从所述前壳11之不同角度的出 风口111吹出。

工作时，所述电机15带动所述风轮21旋转，使空气从所述后壳12的进风口121流入，经过所述风道架3所形成的内部风道，然后从所述前壳11的出风口111吹出，用户手动来转动所述第一旋钮41之第一拨动旋钮411，使所述第一旋钮41之第一主动齿轮412带动所述第一从动齿轮42转动，从而使所述上风道架31转动，来调整所述风道架3之上风道架31所形成的内部风道之出风角度方向，达到调整流入塔式风扇内空气的流动方向，使得流入塔式风扇内的空气能够从所述前壳11上部之不同角度的出风口111吹出。
参见图7,第一从动齿轮42可以与上风道架31做成一个整体，一般来说，第一从动齿轮42和上风道架31为工程塑料，可以一次性注塑而成。在图7的本实施例之转动机构装配时的局部剖视示意图中可以看出，所述第一旋钮41之第一拨动旋钮411的上凸轴4111活动地设置在所述前壳11和后壳12形成的容腔上端之凹槽内，而将第一旋钮41之第一主动齿轮412的下凸轴4121活动地设置在所述风轮轴承支架23之凹槽内，所述第一旋钮41之第一主动齿轮412与所述第一从动齿轮42相互啮合。
参见图8,所述上风道架31一般包括第一上端板311和第一下端板312，以及分别与第一上端板311和第一下端板312联接的第一弧形竖立侧板313，上风道架31的第一上端板311、第一下端板312和第一弧形竖立侧板313之间形成了一条通道，该条通道就是所述上风道架31所形成的内部风道，流入塔式风扇内的空气从该条通道的一端进，从该条通道的另一端出，只要将所述上风道架31转动，由于有上风道架31的第一弧形竖立侧板313的存在和阻挡，就可以使该上风道架31所形成的内部风道之出风角度方向发生改变。上风道架31除了对流入塔式风扇内之上部空气起导向作用外，其作用还有可以增大风轮21上部周围的风压，使流入塔式风扇内之空气能够从前壳11上部的各出风口111高速流出。为了使上风道架31的结构更牢固，有的上风道架31还包括分别与第一上端板311和第一下端板312联接的第一竖立加强板314，该第一竖立加强板314与第一弧形竖立侧板313之间有一定的距离，这样就使得上风道架31的第一上端板311、第一下端板312、第一弧形竖立侧板313和第一竖立加强板314之间形成了两条通道，该两条通道就是所述上风道架31所形成的内部风道，流入塔式风扇内的空气从该上风道架31的一条通道进，从另一条通道出，只要将所述上风道架31转动，由于有第一弧形竖立侧板313和第一竖立加强板314的存在和阻挡，也可以使该上风道架31所形成的内部风道之出风角度方向发生改变。
参见图9,所述下风道架32一般也包括第二上端板321和第二下端板322，以及分别与第二上端板321和第二下端板322联接的第二弧形竖立侧板323，下风道架32的第二上端板321、第二下端板322和第二弧形竖立侧板323之间形成了一条通道，该条通道就是 所述下风道架32所形成的内部风道，流入塔式风扇内的空气从该条通道的一端进，从该条通道的另一端出，当然也只要将所述下风道架32转动，由于有下风道架32的第二弧形竖立侧板323的存在和阻挡，也可以使该下风道架32所形成的内部风道之出风角度方向发生改变。下风道架32除了对流入塔式风扇内之下部空气起导向作用外，其作用还有可以增大风轮21下部周围的风压，使流入塔式风扇内之空气能够从前壳11下部的各出风口111高速流出。为了使下风道架32的结构更牢固，有的下风道架32还包括分别与第二上端板321和第二下端板322联接的第二竖立加强板324，该第二竖立加强板324与第二弧形竖立侧板323之间有一定的距离，这样就使得下风道架32的第二上端板321、第二下端板322、第二弧形竖立侧板323和第二竖立加强板324之间形成了两条通道，该两条通道就是所述下风道架32所形成的内部风道，流入塔式风扇内的空气从该下风道架32的一条通道进，从另一条通道出，当然也只要将所述下风道架32转动，由于有弧形竖立侧板323和竖立加强板324的存在和阻挡，也可以使该下风道架32所形成的内部风道之出风角度方向发生改变。
参见图9,所述下风道架32的第二上端板321的顶部设有一个向上凸出的第一耳仔3212，该第一耳仔3212上设有第一通孔；所述下风道架32的第二下端板322的底部设有一个向下凸出的第二耳仔3222，该第二耳仔3222上设有第二通孔；借助第二上端板321之第一耳仔3212的第一通孔和第二下端板322之第二耳仔3222的第二通孔，就可用两枚螺丝将下风道架32固定在前壳11上。
参见图8,所述上风道架31的第一上端板311的顶部中央设有一个向上凸出的第一圆筒凸台3111，所述上风道架31的第一下端板312中央设有一个中心通孔3121。参见图8,所述下风道架32的第二上端板321的顶部中央设有一个向上凸出的第二圆筒凸台3211。参见图5,所述风轮轴承支架23上设有一圈滑槽239。参见图5至图9,所述上风道架31之第一上端板311的第一圆筒凸台3111位于所述风轮轴承支架23的滑槽239内，所述下风道架32之第二上端板321的第二圆筒凸台3211位于所述上风道架31之第一下端板312中央的中心通孔3121内，这样使所述上风道架31活动地设置在所述下风道架32和风轮轴承支架23上，可以自由转动。参见图9,标号3221为所述下风道架32之第二下端板322中央的一个中心通孔，电机15的转轴可以从该下风道架32之第二下端板322的中心通孔3221穿越。
实施例一塔式风扇的风道架3之下风道架32固定不动，而风道架3之上风道架31可以自由转动，这样就可以使得流入塔式风扇内的空气通过风道架3之下风道架32后从所述前壳11之下部的出风口111吹向一个角度范围的人群，能享受到该塔式风扇吹出来的凉爽的风，而流入塔式风扇内的空气通过风道架3之上风道架31后从所述前壳11之上 部的出风口111吹向另一个角度范围的人群，也能享受到该塔式风扇吹出来的凉爽的风，一台像实施例一这样的塔式风扇就相当于两台现有技术之塔式风扇的效果，节约资源和能源。
在实施例一中的塔式风扇也还以包括设置在电机支架14下方的摆头机构，该摆头机构同现有技术的摆头机构，为常规设计，是现有技术，在此也不再赘述。
实施例一中的塔式风扇可以稍微变形，即可以将风道架3之上风道架31设计为固定不动，而风道架3之下风道架32设计为可以自由转动；或者是将风道架3之上风道架31和下风道架32都设计为可以自由转动；或者是将上风道架31和下风道架32做成一个整体，即为风道架3，而风道架3设计为可以自由转动；它们的结构同实施例一的结构基本类似，在此不再赘述。
