Description

清洁吸尘设备的过滤器的方法及吸尘设备 技术领域
本发明涉及清洁设备技术领域，尤其涉及一种清洁吸尘设备的过滤器的方法及吸尘设备。

桶式吸尘器由于其吸尘效率高而在公司或大商场等清洁面积较大的工作场景中得到广泛应用，通过桶式吸尘器，用户可快速地完成清洁工作，以此，可节省用户的时间，提高用户体验。桶式吸尘器的集尘桶中，通常设有过滤器，通过过滤器对含尘气流进行过滤，含尘气流通过过滤器后，部分灰尘会留在过滤器上，若不能及时清除灰尘，过滤器上的灰尘会逐渐累积，从而过滤器存在堵塞的可能，并因此影响吸尘器的正常工作。
以此，现有的桶式吸尘器大多可对过滤器进行清洁，且存在各种各样的对过滤器进行清洁的方法，其中，下述对过滤器进行清洁的方法最为广泛使用。具体来说，所述清洁吸尘器的过滤器的方法包含：桶式吸尘器的外壳上设有按钮，壳体内设有与按钮相连接的舵机或电磁铁，舵机或电磁铁可打开或关闭吸尘器的自清洁口阀门。当用户需要对过滤器进行清洁时，可先关闭吸尘器的吸口的阀门，并保持吸尘器的电机正常工作，此时集尘桶内的负压使得过滤器收缩，通过按压按钮，驱动舵机或电磁铁打开自清洁口的阀门，从而气流可由自清洁口的阀门进入集尘桶，冲击过滤器，并将过滤器胀起，以此，过滤器上集聚的灰尘可被抖落。用户通过反复操作按钮，可使得过滤器上的灰尘逐渐脱落，从而对过滤器进行清洁。
然而上述对过滤器进行清洁的方法存在以下问题：用户仅能通过感知吸尘器的工作效率降低，才能了解到过滤器的堵塞状况，用户体验差，而且可能发生过滤器已故障而不知的情况，从而使得吸尘器的电机长期超负荷工作，影响吸尘器的使用寿命；进行过滤器的清洁时，用户需不停地操作按钮，不能完全自动进行，影响用户体验。

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，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做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。
在本发明的描述中，需要说明的是，术语“上”、“下”、“底”、“内”、“外”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发明和简化描述，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发明的限制。此外，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等的特征可以明示或隐含地包含一个或者更多个该特征。
为达到上述目的，本发明提供了一种清洁吸尘设备的过滤器的方法及吸尘设备。所述吸尘设备具体为一种桶式吸尘器，当然，在其他实施例中，所述吸尘设备也可以是其他设有过滤器的吸尘器，这里不再赘述。
请具体参考图1-图3，本发明提供了一种吸尘设备，所述吸尘设备包含集尘组件1，根据所述吸尘设备的种类及大小不同，所述集尘组件1具体可以是集尘桶，尘盒或尘箱，在本发明的优选实施例中，所述集尘组件1是集尘桶。所述集尘组件1的上方还设有机头组件4，所述机头组件4与所述集尘组件1可以是通过卡扣可拆卸连接，也可以是通过螺钉等固定连接。所述机头组件4包含电机43及叶轮(未图示)，所述电机43可带动所述叶轮转动，并由此产生吸力，以使得外部空气进入所述集尘组件1，具体来说，所述集尘组件1设有吸口3，所述吸尘设备工作时，所述电机43驱动所述叶轮转动，从而含尘气流由所述吸口3进入所述集尘组件1。所述机头组件4还包含基座41，所述基座41与所述机头组件4的外壳限定出电机腔室，所述电机43收容于所述电机腔室，进一步地，在本发明的一实施例中，所述电机43安装于所述基座41。
所述吸尘设备还包含过滤器2，所述过滤器2具体包含过滤支架21及过滤网22，所述过滤网22可拆卸地安装于所述过滤支架21，当所述过滤网22使用时间较长时，用户可通过更换新的过滤网22以改善所述过滤器2的过滤效果，具体来说，所述过滤器2还包含按压件(未图示)，所述按压件设于所述过滤支架21与所述过滤网22的连接处，用户可操作所述按压件2，以使得所述过滤网22自动与所述过滤支架21分离，以此，用户无需直接接触所述过滤网22，便可以进行所述过滤网22的拆卸，提高了用户体验。所述过滤器2在本发明的优选实施例中，与所述机头组件4的基座41可拆卸连接，在进行所述吸尘设备的装配时，可以是先将所述过滤器2与所述机头组件4相连，后再将所述过滤器2与所述机头组件4一同与所述集尘组件1相连，当然，需要注意的是，其他实施例中，所述过滤器2也可以 仅是安装于所述集尘组件1中，并不与所述机头组件4相连。
所述机头组件4还包含托盘42，所述托盘42安装于所述基座41，并设于所述叶轮的下方，且所述托盘42限定出所述电机腔室的进气口44。具体来说，当所述吸尘设备进行吸尘作业时，含尘气流由所述吸口3进入所述集尘组件1，穿过所述过滤器2的过滤网22后，灰尘部分留在所述过滤网22上，部分落入所述集尘组件1内，经过过滤的气流则由所述进气口44进入所述电机腔室，并由出口5离开所述吸尘设备。当所述吸尘设备使用了一段时间后，所述过滤网22上的灰尘逐渐累积，此时的吸尘设备进行吸尘作业时，所述过滤网22上的灰尘会影响含尘气流的通过，造成所述集尘组件1内所述过滤器2外的部分的气压减少，并表现为所述过滤网22收缩，以此，所述吸尘设备的工作效率会降低。若不及时对所述过滤器2进行清洁，则所述过滤网22上的灰尘会越积累越多直至堵塞所述过滤网22，所述吸尘设备的吸尘效率会进一步下降，且所述电机43会长期处于超负荷工作，进一步地影响所述吸尘设备的使用寿命。
在本发明的一实施例中，所述基座41与所述托盘42之间限定出自清洁通道，所述自清洁通道的气流出口设于所述过滤器2内，同时所述机头组件4上还自清洁口9，在本实施例中，所述清洁口9旁还设有清洁阀门6，通过所述清洁阀门6，可打开或关闭所述自清洁口9，外部气流可由所述清洁阀门6进入所述自清洁通道。具体来说，当进行所述吸尘设备的所述过滤器2的清洁时，控制所述清洁阀门6打开，所述吸尘设备的所述电机43工作并带动所述叶轮转动，从而外部气流由所述清洁阀门6进入所述自清洁通道，并由自清洁通道的气流出口进入所述过滤器2内。当所述清洁阀门6关闭时，由于所述过滤器2上集聚灰尘，含尘气流无法顺利通过所述过滤网22，所述集尘组件1内所述过滤器2外的部分的气压减小，所述过滤网22收缩，以此，当所述清洁阀门6打开时，由所述自清洁通道流至所述过滤器2的外部气流冲击所述过滤网22，并使得所述过滤网22胀起，集聚在所述过滤网22上的灰尘会被抖落，循环多次打开及关闭所述清洁阀门6，可进一步地对集聚在所述过滤网22上的灰尘进行清洁。需要注意的是，在本发明的另一实施例中，所述吸口3处还设有吸尘阀门7，对所述过滤器2进行清洁时，可关闭所述吸尘阀门7。具体来说，对所述过滤器2进行清洁时，可先关闭所述吸尘阀门7，当所述吸尘设备工作时，所述电机43带动所述叶轮转动以产生吸引力，由于所述吸尘阀门7关闭，气流无法进入所述集尘组件1，以此，所述集尘组件1内所述过滤器2外的部分的气压越来越小，所述过滤器22的缩起程度更高，此时打开所述清洁阀门6，则所述外部气流会使得所述过滤网22的胀起程度更高，并进一步地冲击所述过滤网22，循环多次打开及关闭所述清洁阀门6，所述过滤器2可得到更高效地清洁。
本发明的优选实施例中，所述吸尘设备还包含压力传感器(未图示)，所述压力传感器 设于所述集尘组件1内，且所述压力传感器设于所述过滤器2外。具体来说，在本实施例中，所述压力传感器设于所述过滤器2旁，与所述过滤器2临近，通过所述压力传感器，可获得所述集尘组件1内所述过滤器2外的部分的压力值，通过所述压力值，可判断所述过滤器2的堵塞程度。所述吸尘设备还设有控制组件(未图示)，所述控制组件包含存储器和处理器，所述存储器存储有计算机程序，所述处理器执行所述计算机程序时实现吸尘设备的控制，具体来说，所述控制组件可以是单片机或其他具有存储运算处理功能的装置，所述控制组件可根据所述压力传感器获得的所述压力值控制所述吸尘设备进行作业，包含但不限于：以更高效率进行吸尘、执行过滤器的清洁、发出警报、停止工作等。
请具体参考图4-8，本发明的一实施例提供了一种清洁吸尘设备的过滤器的方法，所述吸尘设备依据过滤器堵塞程度不同而具有多个不同清洁状态，不同所述清洁状态各自对应不同的清洁频率，所述方法包含：
S1:检测所述吸尘设备的清洁状态；
S2：以所述吸尘器的清洁状态所对应的清洁频率对所述过滤器进行清洁。。
进一步地，在本发明的优选实施例中，所述吸尘设备包含第一清洁状态和第二清洁状态，所述第一清洁状态对应第一清洁频率，所述第二清洁状态对应第二清洁频率，所述第一清洁频率低于所述第二清洁频率。
针对于步骤S1，在本发明的一实施例中，请具体参考图5，所述“检测所述吸尘设备的清洁状态”包含：
S11:获得所述压力传感器检测到的压力值；
S12:检测所述压力值是否大于预设第一压力值；
S131:若是，则所述吸尘设备处于所述第一清洁状态，S132:若否，则所述吸尘设备处于所述第二清洁状态。
具体来说，在本发明的一实施例中，通过所述压力传感器，可获得所述集尘组件1内所述过滤器2外的部分的压力值，所述控制组件可将所述压力值与存储于存储器的预设第一压力值进行比较。当所述压力值大于所述预设第一压力值时，说明所述过滤器2堵塞程度较低，对所述吸尘设备的清洁效率影响较小，所述吸尘设备此时仍处于第一清洁状态；当所述压力值不大于所述预设第一压力值时，则说明所述吸尘设备清洁效率降低，所述过滤网2上已集聚灰尘，所述吸尘设备此时已处于第二清洁状态。需要注意的是，所述吸尘设备根据所过滤器的堵塞程度不同，也可以还包含其他清洁状态，在其他实施例中，也可以包含第二压力值，所述第二压力值低于所述第一压力值，当所述压力传感器获得的压力值低于所述第二压力值，说明所述过滤器2的堵塞程度更高了，此时需要以更高的清洁频率进行清洁。
需要注意的是，在其他实施例中，若所述控制组件为附带压力传感器模块的单片机，则此时，所述“检测所述吸尘设备的清洁状态”包含：
获得所述压力传感器检测到的压力值；
根据所述压力值与电流值的对应关系，获得所述压力传感器检测到的所述压力值所对应的所述电流值；
检测所述电流值是否大于预设第一电流值；
若是，则所述吸尘设备处于所述第一清洁状态，若否，则所述吸尘设备处于所述第二清洁状态。
具体来说，在本发明的一实施例中，通过所述压力传感器，可获得所述集尘组件1内所述过滤器2外的部分的压力值，所述单片机可将所述压力值转化为其可识别的电流值，并检测所述电流值是否大于存储于存储器的预设第一电流值。当所述电流值大于所述预设第一电流值时，说明所述过滤器2的堵塞程度较低，对所述吸尘设备的清洁效率影响较小，所述吸尘设备此时仍处于第一清洁状态；当所述电流值不大于所述预设第一电流值时，则说明所述吸尘设备清洁效率降低，所述过滤网2上已集聚灰尘，所述吸尘设备此时已处于第二清洁状态。
针对步骤S2，以所述吸尘设备的清洁状态所对应的清洁频率对所述过滤器进行清洁。
具体到本发明的优选实施例中，当所述吸尘设备处于所述第一清洁状态时，所述过滤器2的堵塞程度较低，所述吸尘设备按照第一清洁频率对所述过滤器进行清洁；当所述吸尘设备处于所述第二清洁状态时，所述过滤器2的堵塞程度较高，所述吸尘设备按照第二清洁频率对所述过滤器2进行清洁，所述第一清洁频率低于所述第二清洁频率。以此，无论所述吸尘设备处于所述第一清洁状态还是处于所述第二清洁状态，所述吸尘设备都在对所述过滤器2进行清洁，从而，所述过滤器2更难以堵塞，所述吸尘设备的吸尘效率高。
所述方法还包含：在至少一个所述清洁状态下保持所述吸尘设备的吸口打开，并且在至少另一所述清洁状态下使所述吸尘设备的吸口关闭。
具体到本发明的一实施例中，请具体参考图6，所述“以所述吸尘设备的清洁状态所对应的清洁频率对所述过滤器进行清洁”包含：
所述吸尘设备处于所述第一清洁状态时，保持所述吸尘设备的吸口打开，所述吸尘设备每隔第一预设时间打开所述自清洁口；
所述吸尘设备处于所述第二清洁状态时，保持所述吸尘设备的吸口关闭，所述吸尘设备每隔第二预设时间打开所述自清洁口，其中，所述第二预设时间小于所述第一预设时间。
请参考图3，本发明的吸尘设备还包含带电运动组件7，通过所述带电运动组件7，所述 控制组件可控制所述清洁阀门6打开及关闭。具体来说，所述带电运动组件7在本实施例中为舵机，所述舵机与连接组件8相连，所述连接组件8包含传动件81，所述传动件8一端与所述清洁阀门6相连，另一端与所述舵机相连。当所述控制组件获得打开所述清洁阀门6的指令时，控制所述舵机向下运动，则所述传动件81绕固定轴顺时针向下转动，并使得与所述传动件81相连的所述清洁阀门6绕所述固定轴顺时针向上转动，从而所述清洁阀门6开启；此时，与所述传动件81相连的弹性件82被压缩，而当所述控制组件获得关闭所述清洁阀门6的指令时，控制所述舵机回复原位置，则所述传动件81受到所述弹性件82的弹性力并回复至原位置，从而所述清洁阀门6关闭。需要注意的是，在本发明的优选实施例中，所述吸尘阀门7也对应设有带动运动部件，通过所述带电运动组件，所述控制组件可控制所述吸尘阀门7的打开及关闭。同时，还需要注意的是，所述带电运动组件7为舵机仅是一种实施例，在其他实施例中，所述带电运动部件可以是电磁铁，或其他可实现所述清洁阀门6及所述吸尘阀门7关闭或打开的装置。
针对步骤“所述吸尘设备处于所述第一清洁状态时，保持所述吸尘设备的吸口打开，所述吸尘设备每隔第一预设时间打开所述自清洁口”，在本发明的优选实施例中，所述吸尘设备无需经常关闭吸口3以停止吸尘作业，也无需经常以较高的清洁频率对过滤器2进行清洁。具体来说，即便所述吸尘设备的过滤器2的堵塞程度低，即所述吸尘设备正处于所述第一清洁状态，所述吸尘设备也进行所述过滤器2的清洁。当所述压力传感器检测到所述压力值高于预设第一压力值时，说明所述吸尘设备正处于所述第一清洁状态，所述过滤器2正常工作，堵塞程度低。此时，所述吸尘设备继续进行吸尘作业，并保持所述吸尘阀门7打开，同时，每隔所述第一预设时间打开所述清洁阀门6，以此，所述吸尘设备每隔所述第一预设时间会对所述过滤器2进行一次自清洁，从而使得所述过滤网22上更难以集聚灰尘，降低了所述过滤器2堵塞的可能性，所述吸尘设备可长期处于过滤器堵塞程度较低的状态，无需经常停止正常的吸尘工作以深度清洁过滤器，并使得用户可更为顺畅地进行清洁工作，提高了用户体验。需要注意的是，在优选的实施例中，所述第一预设时间通常设置的较大，以使得所述吸尘设备处于第一清洁状态时，不会过于频繁地执行过滤器的清洁，从而影响工作效率及用户体验。
针对步骤“所述吸尘设备处于所述第二清洁状态时，保持所述吸尘设备的吸口关闭，所述吸尘设备每隔第二预设时间打开所述自清洁口，其中，所述第二预设时间小于所述第一预设时间”，在本发明的优选实施例中，所述吸尘设备每隔所述第一预设时间便会对所述过滤器2进行一次自清洁，若所述吸尘设备的所述过滤器2仍堵塞了，则所述吸尘设备以更高的频率进行自清洁，并提高自清洁的强度。具体来说，当所述压力传感器检测到所述压力值低 于预设第一压力值时，说明所述吸尘设备正处于第二清洁状态，则所述吸尘设备关闭所述吸尘阀门7，并每隔第二预设时间打开所述清洁阀门6。当所述吸尘阀门7关闭时，所述集尘组件1内所述过滤器2外的部分的气压更小了，所述过滤器22的缩起程度更高，此时打开所述清洁阀门6，则所述外部气流会冲击所述过滤网22，并使得所述过滤网22膨胀，从而更高效地抖落所述过滤网22上集聚的灰尘。当然，在本发明的优选实施例中，所述第二预设时间远小于所述第一预设时间，以此，当所述过滤器2已经堵塞时，所述吸尘设备以更高的频率进行自清洁。需要注意的是，在其他实施例中，所述吸尘设备以所述第二清洁频率对所述过滤器进行清洁时，也可以是不关闭所述吸尘阀门7，仅提高清洁频率，也可以有效地对所述过滤器进行清洁。
在本发明的第一实施例中，请具体参考图7，所述方法还包含：
S3：当所述吸尘设备处于所述第二清洁状态时，记录所述吸尘设备以所述第二清洁频率对所述过滤器进行清洁的第一清洁时间；
S4：检测所述第一清洁时间是否大于第三预设时间，并检测所述压力值是否大于预设第一压力值；
S5:若所述第一清洁时间大于第三预设时间，且所述压力值始终小于所述预设第一压力值，则所述吸尘设备停止工作和/或发出警报。
具体来说，当所述吸尘设备处于所述第二清洁状态时，所述吸尘设备以所述第二清洁频率对所述过滤器2进行清洁，同时开始记录所述吸尘设备进行清洁的第一清洁时间，当所述第一清洁时间大于所述第三预设时间，且压力值始终小于所述预设第一压力值，则说明所述过滤器2存在故障或所述过滤器2灰尘积累过多，当前对所述过滤器2进行清洁的清洁频率仍较低，以此，为了避免对吸尘设备造成损害，所述吸尘设备停止工作和/或发出警报，从而用户可察觉到吸尘设备的异常，并及时进行查验，降低了吸尘设备长期异常工作的可能，避免所述吸尘设备的电机长期处于超负荷工作状态，延长了吸尘设备的使用寿命，提高安全性。需要注意的是，在其他实施例中，所述方法也可以是包含：记录所述吸尘设备以所述第二清洁频率对所述过滤器进行清洁时，清洁所述过滤器的总次数；检测所述总次数是否大于第一预设次数，并检测所述压力值是否大于预设第一压力值；若所述总次数大于第一预设次数，且所述压力值始终小于所述预设第一压力值，则所述吸尘设备停止工作和/或发出警报。具体来说，在其他实施例中，也可以是记录所述吸尘设备清洁所述过滤器2的次数，而不局限于记录清洁所述过滤器2的时间。当然，还需要注意的是，所述方法还包含：若所述第一清洁时间小于所述第三预设时间，且所述压力值大于所述预设第一压力值，则所述吸尘设备由所述第二清洁状态切换至所述第一清洁状态。具体来说，当所述吸尘设备按照所述第二清 洁状态进行了一段时间的作业，而所述压力值再次大于所述预设第一压力值，则说明所述吸尘设备的所述过滤器2的堵塞程度降低了，此时，所述吸尘设备切换至所述第一清洁状态，继续进行吸尘作业。
进一步地，在本发明的第二实施例中，请具体参考图8，所述方法还包含:
S10:当所述吸尘设备处于所述第二清洁状态时，记录所述吸尘设备以所述第二清洁频率对所述过滤器进行清洁的第一清洁时间；
S20:检测所述第一清洁时间是否大于第三预设时间，并检测所述压力值是否大于所述预设第一压力值；
S30:若所述第一清洁时间大于第三预设时间，且所述压力值始终小于所述预设第一压力值，则所述吸尘设备以第三清洁频率对所述过滤器进行清洁，其中，所述第三清洁频率大于所述第二清洁频率。
S40:记录所述吸尘设备以所述第三频率对所述过滤器进行清洁的第二清洁时间；
S50:检测所述第二清洁时间是否大于第四预设时间，并检测所述压力值是否大于所述预设第一压力值；
S60:若所述第二清洁时间大于第四预设时间，且所述压力值始终小于所述预设第一压力值，则所述吸尘设备立即停止工作。
具体来说，当所述吸尘设备处于所述第二清洁状态时，所述吸尘设备以所述第二清洁频率对所述过滤器2进行清洁，同时开始记录所述吸尘设备进行清洁的第一清洁时间，当所述第一清洁时间大于所述第三预设时间，且压力值始终小于所述预设第一压力值，则说明所述过滤器2存在故障或所述过滤器2灰尘积累过多，当前对所述过滤器2进行清洁的清洁频率仍较低。为了进一步确定所述过滤器2是存在故障还是当前清洁频率不够，则此时所述吸尘设备以更高的清洁频率进行过滤器的清洁，并记录所述吸尘设备清洁过滤器的第二清洁时间，若所述第二清洁时间大于第四预设时间，压力值仍始终小于所述预设第一压力值，则说明吸尘设备的过滤器2发生故障，此时，吸尘设备直接停止工作，当然，所述吸尘也可以发出警报以提醒用户进行检查。需要注意的是，所述方法还包含：若所述第二清洁时间不大于所述第四预设时间，所述压力值不小于所述预设第一压力值，则所述吸尘设备由当前清洁状态切换至所述第一清洁状态。具体来说，当所述吸尘设备按照更高的清洁频率进行了一段时间的作业，而所述压力值再次大于所述预设第一压力值，则说明所述吸尘设备的所述过滤器2的堵塞程度降低了，所述吸尘设备的过滤器2未故障，此时，所述吸尘设备切换至所述第一清洁状态，继续进行作业。
进一步地，所述方法还包含：当所述吸尘设备由所述第一清洁状态切换至所述第二清洁 状态时，所述吸尘设备以所述第一清洁频率对所述过滤器完成一次清洁后，立即以所述第二清洁频率对所述过滤器进行清洁。
具体来说，在本发明的一实施例中，当所述吸尘设备检测到压力值低于所述预设第一压力值时，所述吸尘设备由所述第一清洁状态切换到所述第二清洁状态时，所述吸尘设备不会立即按照更高的频率进行吸尘设备的过滤器的清洁，而是以当前较低的清洁频率完成一次过滤器的清洁后，再切换到更高的清洁频率进行过滤器的清洁，以此，吸尘设备可更为稳定地进行作业，噪音更小。当然，还需要注意的是，在其他实施例中，当所述吸尘设备由所述第一清洁状态切换至所述第二清洁状态时，所述吸尘设备终止以所述第一清洁频率对所述过滤器进行清洁，并立即以所述第二清洁频率对所述过滤器进行清洁，具体来说，在其他实施例中，所述吸尘设备也可以是立即终止当前对过滤器进行清洁的作业，并立即以所述第二清洁频率对所述过滤器进行清洁，以此，可更高效地进行过滤器的清洁，提高吸尘设备的工作效率。
本发明中应用了具体实施例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
