Description

一种便携空气投影装置 技术领域
本发明涉及投影技术，特别是涉及一种便携空气投影装置。
背景技术
人们在商务或者娱乐活动中，常常需要向其他人演示或者分享一些电子材料，例如演示文件、视频、网站等等，通常人们带上电脑，并将电脑与视频外设相连接，这些外设一般包括投影仪、电视等，其中投影仪的价格较高，需要的空间较大，并且需要一面白墙或投影幕布，这给投影的普及带来的困难。电视虽然普及较广，但由于重量太大，以及对于电源的需要，造成人们不能随身携带电视，从而不能随时向他人分享自己的电子信息。
随着时代的发展，电脑也逐渐被手机所取代，也实现了手机与投影仪和电视的连接。虽然手机可以代替电脑的部分功能并可以方便的随身携带，但同样存在上述的问题，即投影仪和电视不能随身携带，或者在一些特殊的场合，例如汽车、火车等交通工具内，需要实现手机屏幕的投影则会非常困难。
而很多商业机会，恰恰存在于在汽车、火车等交通工具内的短时聊天或者在候机厅内的偶然会见聊天，而在这些场景下如果涉及演示或者分享随身的电子材料，还没有提供出能够随身便携的进行即时展示的投影设备。
发明内容

4)本发明实施例通过凸出外壳的扇形结构的蒸汽出口，可以以较小的尺 寸实现大屏幕，增加了产品的便携性。
5)本发明实施例通过设置吸水软管，取水方便，缩小了储水槽体积，增加了产品的便携性。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是本发明实施例的便携空气投影装置的立体结构图；
图2是本发明实施例的便携空气投影装置的俯视图；
图3是本发明实施例的便携空气投影装置的内部结构图；
图4是本发明实施例的便携空气投影装置的与手机配合使用图；
图5是本发明实施例的便携空气投影装置的蒸汽出口结构图。
具体实施方式
图1、图2是本发明一个实施例的便携空气投影装置的立体结构图和俯视图，如图1、图2所示，本发明实施例提供一种便携空气投影装置，包括：
蒸汽投影幕发生装置，能够通过蒸汽出口110产生气态幕墙；
通讯接口120，能够信号连接便携移动通信设备；
信号收发和处理单元，用于通过所述通讯接口接收来自所述便携移动通信设备的显示信号，并将所述显示信号转换为投影控制信号；
投影镜头130，用于根据所述投影控制信号在所述气态幕墙上产生投影显示屏幕。
可见，本发明实施例中，通讯接口接收来自手机的信号，信号经过处理后，由投影镜头发出光学影像投射在蒸汽出口产生的气态幕墙上，由于气态幕墙肉眼几乎看不到，这样手机的屏幕信息仿佛像一道屏幕显示在空气中。
因此，本发明实施例通过气态幕墙进行手机屏幕投影，无需投影仪，无需有形屏幕或墙壁，也无需电视或电脑，可以随时随地的进行随身电子材料的演示或分享，非常适合于在汽车、火车等交通工具内进行短时聊天时的场景，能进行非常有效的即时沟通，能够有效促进商业活动的开展。
如图2所示，所述蒸汽出口为长条形，所述长条形的两端具有调节蒸汽射出的角度的调节板111，从而调节所述气态幕墙的侧边范围。将调节板111向两边倾斜，会增加蒸汽向两边射出的角度，进而增加空气投影屏幕的面积。
图3是本发明实施例的便携空气投影装置的内部结构图，如图3所示，便携空气投影装置内部，除了信号收发和处理单元和处理器单元之外，还包括：
系统控制单元，用于：通过调节蒸汽的流量和流速，来控制所述气态幕墙的高度。当需要较大屏幕的时候，就提高流量和流速，使得蒸汽流范围扩大，从而气态幕墙的面积扩大。
所述系统控制单元，还用于：根据所述气态幕墙的所述侧边范围和所述气态幕墙的所述高度来调节所述投影镜头的投影角度和焦距，从而控制所述投影显示屏幕的范围。这可以使得投影显示屏幕尽量与气态幕墙的有效范围相匹配，防止蒸汽浪费，例如如果气态幕墙很大，而投影显示屏幕很小，需要通过投影角度和焦距来扩大投影显示屏幕，或者减小蒸汽流速来缩小气态幕墙。
如图1、图2所示，便携空气投影装置还包括：
红外探测仪140，位于所述气态幕墙的后侧，用于：探测人的手指在所述投影显示屏幕上的动作，生成触摸控制信号，并通过所述通讯接口将所述触摸控制信号发送给所述便携移动通信设备。
图中红外探测仪140为2个，当然也可以为更多个。红外探测仪设置在屏幕后侧，这样不会因为人手的遮挡造成探测数据的错误，进而造成误操作。
进一步的，还可以具有外配的指套，所述指套内设有重力感应器和信号发射装置，用于产生针对所述投影显示屏幕的所述触摸控制信号。
图4是本发明实施例的便携空气投影装置的与手机配合使用图，如图4所示，便携空气投影装置的壳体可以设计的与手机壳体相匹配，直接在通讯接口处进行连接，连接后浑然一体，携空气投影装置产生投影图像，并通过手机的扬声器200进行声音播放。
在本发明的一个实施例中，便携空气投影装置具有内置电池，用于给所述便携移动通信设备进行充电。因此，便携空气投影装置在不做投影仪用时，可以作为充电宝使用，使得用户更愿意随身携带。所述便携移动通信设备为手机或者平板电脑。
其中，通信接口不限于USB接口，可以是蓝牙或者其他无线接口。
图5是本发明实施例的便携空气投影装置的蒸汽出口结构图。如图5所示，蒸汽出口为凸出外壳的扇形结构；所述扇形结构内部设置有放射性排列的多个 风道，每个风道具有流速控制阀门，通过流速控制使得所述气态幕墙呈矩形结构。
在该实施例中，蒸汽出口设置为凸出外壳的扇形结构，是可以呈扇形放射状向外送蒸汽，从而用小的出风口实现大的幕墙，有利于出风口的小型化，有利于便携。因为如果仅仅是一个平面直线出风口，其出风角度有限，难以实现远远超过出风口宽度的大屏幕。
凸出外壳的扇形结构，可以是可折叠或可伸缩的，在不用的时候折叠或者缩回去，保持外观平整。
另外，如图5所示，因为屏幕投影一般是矩形的，如果气态幕墙放射了个扇形会造成蒸汽浪费，所以通过对每个风道的控制尽量使得气态幕墙整体大致为矩形，可以节约蒸汽。
在本发明的另一个实施例中，蒸汽投影幕发生装置的储水槽具有吸水软管，所述吸水软管能够直接从外部水容器吸水。这是因为，考虑到小型化和便携，储水槽肯定不能太大，而经常添水又比较麻烦，所以直接弄个吸水管，利用现场的一次性水杯甚至矿泉水瓶作为临时储水槽，既解决了水源，又缩小了便携空气投影装置的体积。
在本发明的另一个实施例中，所述蒸汽投影幕发生装置还据有色素添加模块，用于在产生蒸汽的液体中加入色素。这是因为，在光线不好的时候，透明蒸汽幕墙显示效果会不理想，加入食用色素，使得幕墙透光率下降，类似于真的墙体，可以增加幕墙的投影效果。
进一步的，本发明的另一个实施例中，还可以设置两个蒸汽出口，前面一个出透明的气态幕墙，后面一个出加入食用色素的气态幕墙作为基底，这样还可以实现简单的立体效果。
由上可知，本发明具有以下优势：
1)本发明实施例通过气态幕墙进行手机屏幕投影，无需投影仪，无需有形屏幕或墙壁，也无需电视或电脑，可以随时随地的进行随身电子材料的演示或分享，非常适合于在汽车、火车等交通工具内进行短时聊天时的场景，能进行非常有效的即时沟通，能够有效促进商业活动的开展。
2)本发明实施例通过调节板向两边倾斜，增加蒸汽向两边射出的角度，进而增加空气投影屏幕的面积。
3)本发明实施例通过调节蒸汽的流量和流速来调节气态幕墙的大小，通过调整投影镜头的角度、焦距，来调节投影画面的成像效果。
4)本发明实施例通过凸出外壳的扇形结构的蒸汽出口，可以以较小的尺寸实现大屏幕，增加了产品的便携性。
5)本发明实施例通过设置吸水软管，取水方便，缩小了储水槽体积，增加了产品的便携性。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
