在本公开的描述中,需要说明的是,术语“上”、“下”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本公开和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本公开的限制。
此外,在本公开的描述中,除非另有说明,“多个”的含义是两个或更多。
图1示出了根据本公开示例性实施例的除尘装置的结构示意图。
如图1所示,根据本公开示例性实施例的除尘装置10可用于显示屏并且包括两个喷嘴11和12、两个移动装置21和22、供气装置3以及控制装置4。具体地,喷嘴11和12通过其末端设置的导管与供气装置3气密连接;移动装置21和22与两个喷嘴11和12物理连接,并被配置为将喷嘴11和12移动到预定位置;控制装置4与供气装置3电气连接,并被配置为控制供气装置3的开启或者关闭,从而控制两个喷嘴11和12的喷气。
由此,根据本公开示例性实施例的除尘装置10可通过至少一个移动装置21和22而将喷嘴11和12移动到预定位置,从而实现定点机械除尘, 并提升除尘效果。
具体地,移动装置21或者22一端上设置有喷嘴11或者12,移动装置21或者22的另一端的位置固定,并且移动装置21或者22能够相对于其另一端转动,从而能够将喷嘴11或者12移动到预定位置。例如,移动装置21或者22的另一端可固定在待除尘面的侧面,或者固定在待除尘面之外的其他物体上。通过转动移动装置21或者22,可以将喷嘴11或者12从其初始位置移动至预定的位置。其中,喷嘴11或者12的初始位置为除尘装置关闭时,喷嘴11或者喷嘴12所处的位置,其可位于显示屏的背面或者侧面。喷嘴11或者喷嘴12的预定的位置为除尘装置开启后,喷嘴11或者喷嘴12移动到的位置,下文中将会对喷嘴11或者喷嘴12的预定位置进行详细的介绍,在此不再进行详细的描述。
具体地,移动装置21或者22可以是机械臂。而机械臂可包括机械前臂、机械后臂以及连接机构,机械前臂的一端和机械后臂的一端通过所述连接结构连接,机械后臂的另一端的位置固定并且机械后臂自身能够相对于该机械后臂的另一端做圆锥形运动,连接机构能够调节机械前臂和机械后臂之间的夹角,机械前臂上设置有喷嘴11或者12,通过机械前臂和机械后臂的运动,可将喷嘴11或者12移动到预定位置。值得注意的是,机械后臂自身相对于该机械后臂的另一端做圆锥形运动时,机械后臂与圆锥轴线之间的夹角在0-90度之间;机械前臂和机械后臂之间的夹角在0-180度之间;并且连接机构可以是销轴或者铰链,即机械前臂的一端和机械后臂的一端可通过销轴或者铰链连接。例如,机械后臂的另一端可固定在待除尘面的背面或者侧面,或者固定在待除尘面之外的其他物体上。通过转动机械后臂,并调整机械前臂与机械后臂之间的夹角,可以将喷嘴11或者12从其初始位置移动至预定的位置。
值得注意的是,图1中给出的实施例仅是示意性目的,在其它实施例中,喷嘴和移动装置的数量并非仅限于两个。此外,一个移动装置可以仅将一个喷嘴移动到指定位置,还可以将多个喷嘴移动到指定位置。例如,除 尘装置10可包括四个喷嘴以及两个移动装置,每个移动装置可将两个喷嘴移动到各自指定位置。根据本公开示例性实施例的除尘装置不仅适用于显示屏,还适用于需要定期除尘的其他设备。
为了实现对各个喷嘴气体流速的精确控制,根据本公开的示例性实施例,在喷嘴11和12末端的导管上可设置速度控制装置,并且控制装置4可对速度控制装置进行控制。
具体地,速度控制装置可以是流速控制阀,控制装置4可控制流速控制阀的开口大小,从而调节流经导管的气流的流速。根据本公开的示例性实施例,通过对各个喷嘴气流流速的精确控制,可进一步提升除尘效果。
除尘装置10还可包括两个方向调节装置,当移动装置21和22将喷嘴11和12移动到指定位置后,两个方向调节装置可分别调节喷嘴11以及喷嘴12的方向,使其对准相应的位置。根据本公开的示例性实施例,通过调节各个喷嘴方向,能够实现精确除尘。
进一步地,除尘装置10还可包括两个摆动装置,在两个方向调节装置调节喷嘴11和喷嘴12的方向对准相应的位置后,两个摆动装置可分别控制喷嘴11和喷嘴12的方向在相应的区域内摆动。例如,每个摆动装置可控制喷嘴以小于90度的夹角左右摆动和/或上下摆动。根据本公开的其他实施例,每个摆动装置还可控制喷嘴以小于90度的夹角做圆锥形运动。根据本公开的示例性实施例,通过控制喷嘴11和12在灰尘集中的区域内摆动,有利于去除灰尘集中区域内的灰尘,进一步提升除尘效果。
值得注意的是,由摆动装置实现的功能可以并入到方向调节装置中,即方向调节装置还可以控制喷嘴11和喷嘴12的摆动。
进一步地,控制装置4还可为分别为喷嘴11和12设置喷气时间,而喷嘴11或者喷嘴12在喷气时间达到设置的喷气时间后停止喷气。由此,根据本公开的示例性实施例,可以降低喷嘴11和12持续喷气所导致的能耗。
为了实现除尘装置10的定时启动,除尘装置10还可包括定时装置, 当定时装置期满时,移动装置21和22将喷嘴11和12移动到预定位置,并且控制装置4开启供气装置3。值得注意的是,该定时装置可根据周围环境和/或个人喜好预先设置,例如,在灰尘较多的环境中,可设定在每天的上午6点以及下午6点定时启动除尘装置10,而在灰尘较少的环境中,可设定在每天的上午6点定时启动除尘装置10。根据本公开的示例性实施例,能够实现定期除尘,从而可保持除尘面的持续清洁。
进一步地,除尘装置10还可包括检测装置,该检测装置能够检测待除尘面上的灰尘分布。检测装置可以是能够对待除尘面进行检测的扫描装置,例如,激光扫描装置,通过扫描待除尘面,从而检测待除尘面上灰尘集中的点位(即,灰尘点)和/或灰尘集中的区域。
相应地,方向调节装置可调节喷嘴11和/或喷嘴12的方向对准检测装置检测到的灰尘点。当检测装置检测到的灰尘点周围区域中灰尘密度大于第一阈值时,方向调节装置控制喷嘴11和/或喷嘴12在检测到的灰尘点周围区域内摆动,并且摆动的范围可预先设置。由此,根据本公开的示例性实施例,能够实现精确除尘。
值得注意的是,方向调节装置可包括动力装置和传动装置。其中,动力装置可以是设置在机械臂上的电机,传动装置可以是齿轮传动装置或者蜗杆传动装置,该电机通过齿轮传动装置或者蜗杆传动装置与喷嘴11和/或喷嘴12的一端相连,从而可调节喷嘴11和/或喷嘴12的方向。根据本公开的示例性实施例,方向调节装置还可从控制装置4接收控制信号,从而控制电机的转速和/或转动时间,以及控制齿轮传动装置或者蜗杆传动装置的传动方向。
相应地,当检测装置检测到的灰尘点与预定位置的距离大于第二阈值时,即当灰尘点与喷嘴11或者12之间的距离较远时,控制装置4则会对速度控制装置进行控制,以便增大流经导管的气体的流速,或者控制装置4则会增大喷嘴11或者12的喷气时间。由此,根据本公开的示例性实施例,能够进一步提升除尘效果。
相应地,当检测装置检测到的灰尘点周围区域中灰尘密度大于第三阈值时,控制装置4则会对速度控制装置进行控制,以便增大流经导管的气体的流速,或者控制装置4则会增大喷嘴11或者12的喷气时间。由此,根据本公开的示例性实施例,能够进一步提升除尘效果。
进一步地,供气装置可包括正负电荷发生装置,并通过正负电荷发生装置向喷嘴11和12提供包含正负电荷的气流,以便去除静电。
进一步地,检测装置可进一步配置为:在喷嘴11和12喷气结束后,再次检测待除尘面上的灰尘分布;当检测装置检测到的灰尘分布不满足预定检测条件时,即如果检测到的灰尘分布不满足预定灰尘标准,移动装置21和22使得喷嘴11和12保持在预定位置,并且控制装置4开启供气装置3,从而控制喷嘴11和12喷气;当检测到的灰尘分布满足预定检测条件时,即如果检测到的灰尘分布满足预定灰尘标准,移动装置21和22使得喷嘴11和12回到初始位置,并且控制装置4关闭供气装置3,从而停止喷嘴11和12喷气。根据本公开的示例性实施例,喷嘴11和12的初始位置可位于待除尘面的背面或者侧面,以免对待除尘面的正常使用造成影响。
图2示出了根据本公开实施例的喷嘴的预定位置。
如图2所示,待除尘面为矩形,而喷嘴的预定位置位于待除尘面的四个角的上方。本领域技术人员不难理解,图2所示的喷嘴的预定位置仅是示意性的。根据本公开的另一示例性实施例,喷嘴的预定位置可以仅有一个,并且可位于待除尘面的中心位置。根据本公开的其他示例性实施例,喷嘴的预定位置可以是其他数目,并且可均匀分布在待除尘面的上方。
图3示出了根据本公开的一个实施例的除尘方法的流程图。
如图3所示,在步骤S31中,定时启动除尘装置10。
具体地,当除尘装置10中定时装置期满时,则启动除尘装置10。值得注意的是,该定时装置可根据周围环境和/或个人喜好预先设置,例如,在灰尘较多的环境中,可设定在每天的上午6点以及下午6点定时启动除 尘装置10,而在灰尘较少的环境中,可设定在每天的上午6点定时启动除尘装置10。
在步骤S32中,移动装置21和22将喷嘴11和12移动到预定位置。移动装置21和22与喷嘴11和12的关系以及预定位置的设置上文中已有介绍,在此不再赘述。
在步骤S33中,控制装置4开启供气装置3,从而开始除尘。
在步骤S34中,控制装置4可为分别为喷嘴11和12设置喷气时间,而喷嘴11和喷嘴12在喷气时间达到设置的喷气时间后停止喷气,当所有喷嘴11和12停止喷气后,控制装置4可关闭供气装置3,结束除尘。
在步骤S35中,移动装置21和22使得喷嘴11和12回到初始位置,以免对待除尘面的正常使用造成影响。其中,初始位置可位于待除尘面的背面或者侧面。
图4示出了根据本公开的另一个实施例的除尘方法的流程图。
如图4所示,在步骤S41中,定时启动除尘装置10。
具体地,当除尘装置10中定时装置期满时,则启动除尘装置10。值得注意的是,该定时装置可根据周围环境和/或个人喜好预先设置,例如,在灰尘较多的环境中,可设定在每天的上午6点以及下午6点定时启动除尘装置10,而在灰尘较少的环境中,可设定在每天的上午6点定时启动除尘装置10。
在步骤S42中,移动装置21和22将喷嘴11和12移动到预定位置。移动装置21和22与喷嘴11和12的关系以及预定位置的设置上文中已有介绍,在此不再赘述。
在步骤S43中,除尘装置10中的检测装置能够检测待除尘面上的灰尘分布,例如,检测待除尘面上灰尘点和/或灰尘集中的区域。
在步骤S44中,控制装置4根据检测到的灰尘分布控制速度控制装置并为喷嘴11和12设置喷气时间。
例如,当检测装置检测到的灰尘点与预定位置的距离大于第二阈值时, 即当灰尘点与喷嘴11或者12之间的距离较远时,控制装置4则会对速度控制装置进行控制,以便增大流经导管的气体的流速,或者控制装置4则会增大喷嘴11或者12的喷气时间。或者,当检测装置检测到的灰尘点周围区域中灰尘密度大于第三阈值时,控制装置4则会对速度控制装置进行控制,以便增大流经导管的气体的流速,或者控制装置4则会增大喷嘴11或者12的喷气时间。
在步骤S45中,控制装置4可根据检测到的灰尘分布为除尘装置10设定除尘模式。除尘模式包括定点除尘模式和摆动除尘模式。其中,定点除尘模式是指方向调节装置调节喷嘴11和/或喷嘴12的方向对准检测装置检测到的灰尘点,摆动除尘模式是指摆动装置或者方向调节装置控制喷嘴11和/或喷嘴12在检测到的灰尘点周围区域内摆动。
例如,当检测装置检测到灰尘点,并且灰尘点周围区域中灰尘密度小于第一阈值时,则控制装置4设定定点除尘模式;当检测装置检测到灰尘点,并且灰尘点周围区域中灰尘密度大于第一阈值时,则控制装置4设定摆动除尘模式。
在步骤S46中,控制装置4开启供气装置3,从而开始除尘。
在步骤S47中,当所有喷嘴停止喷气后,检测装置再次检测待除尘面。当检测装置检测到的灰尘分布不满足预定检测条件时,即当检测装置检测到的灰尘分布不满足预定灰尘标准时,返回步骤S44。当检测到的灰尘分布满足预定检测条件时,即当检测装置检测到的灰尘分布满足预定灰尘标准时,执行步骤S48,即控制装置4关闭供气装置3,结束除尘。
在步骤S49中,移动装置21和22使得喷嘴11和12回到初始位置。其中,初始位置可位于待除尘面的背面或者侧面。
基于同样的构思,本公开的实施例还提供了一种显示装置,包括任一上述的除尘装置10以及显示器,其中,除尘装置10设置在显示器的背面或者侧面。根据本公开示例性实施例的显示装置,能够实现定点机械除尘,并提升除尘效果。
需要说明的是,本实施例中的显示装置可以为:显示面板、电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
以上所述,仅为本公开的具体实施方式,但是,本公开的保护范围不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到的变化或替代,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以所述权利要求的保护范围为准。
