本公开涉及充气和抽气设备技术领域，具体而言，涉及一种气泵及其控制方法。
背景技术
现有的充气泵通常包括马达、传动组件、活塞杆、单向阀以及气缸。这种充气泵的原理为马达带动传动组件使得活塞杆在气缸中往复运动，实现打气功能。更为具体地，活塞杆在气缸内的一侧设有弹片，抽气时，外界气体由活塞杆另一侧推开弹片进入到气缸中，而打气时，活塞杆的弹片闭合，气缸中的气体被挤压并冲开气缸末端的单向阀进入到待充气物体中。
目前市面上的充气泵大多都只是利用充气泵的充气功能对物体充气，而其打气过程中另一端的吸气产生的负压则被忽略。目前许多年轻人爱好户外露营，难免会使用较多的充气物品，比如泳圈、橡皮船、充气帐篷、气垫床等。当这些物品在使用完毕后需要人工进行放气、折叠并收纳，而在无压力的状态下气体无法被完成排空，导致收纳不便。现有技术中，充气泵的功能单一，仅有充气功能，没有抽气功能，无法满足使用者的需求。另外，充气泵不能根据物品的内部气体的状态调节吸力压力，不智能。

具体实施方式
下面结合附图和具体实施例对本公开作进一步详细描述，但不作为对本公开的限定。
如图1至图5所示，根据本公开的实施例，提供了一种气泵100，气泵100包括外壳10、气缸20和散热风扇30。外壳10上设置有抽气口11，外壳10内部形成有散热风道12。气缸20设置在外壳10的内部，气缸20的吸气口21与抽气口11连通。散热风扇30设置在散热风道12内，散热风道12的进气端12a与抽气口11连通。
当气泵在充气时，空气从抽气口被吸入气缸，从气缸的排气口排出，通过外接气管进入待充气的物体。同时，散热风扇将空气从抽气口吸入，并使空气通过散热风道以达到散热目的。气泵在吸气时，抽气口通过气管连接待吸气的物体，通过散热风扇和/或气缸的吸力，将空气从抽气口吸入，进而实现抽气功能。本公开的气泵利用气缸的自吸能力和散热风扇形成负压的吸力，在实现充气功能的前提下，还实现了吸气功能，即，一泵两用。
如图1至图5所示，气泵100还包括电磁阀40，电磁阀40安装在散热风道12的进气端12a位置处。电磁阀40用于控制散热风道12的进气端12a与抽气口11的连通和隔断。具体地，电磁阀40具有控制散热风道12的进气端12a与抽气口11连通的第一状态，以及控制散热风道12的进气端12a与抽气口11隔断的第二状态。
气泵100还可以包括控制器(未示出)，控制器与电磁阀40电连接，控制器用于接收 指令信息并控制电磁阀40在第一状态和第二状态之间切换。电磁阀40通过控制散热风道12与抽气口11的连通和隔断，首先控制了散热风道是否有气流进入达到散热作用，而且还能控制抽气口11的吸气压力，也就是选择是气缸20进行抽气，还是气缸20和散热风扇30共同进行抽气。
可选地，如图1至图3所示，气泵100还可包括压力传感器50。压力传感器50可以设置在外壳10内部，用于检测气缸20的吸气压力。控制器可以与电磁阀40和压力传感器50均电连接，由此接收压力传感器50的信号并控制电磁阀40在第一状态和第二状态之间切换。
本公开的气泵通过压力传感器通过检测气缸的吸气压力，来控制电磁阀，以切换气泵的抽气压力。在气泵吸气时，当检测气缸的吸气压力较小时，控制电磁阀切换至第一状态，利用散热风扇进行抽气，吸力的主要来源是散热风扇的转动，此时吸气总量较大，吸气压力较小。在气泵吸气一段时间后，这时当检测气缸的吸气压力较大时，说明被抽气的物品内部的空气被抽走了很多，被抽气的物品发生形变，导致气泵抽取空气的阻力变大，使气缸的吸气压力变大，进而控制电磁阀切换至第二状态，通过气缸来进行抽气，吸力的主要来源是气缸的自吸力，此时吸气总量较少，吸气压力较大，适用于接近抽真空的物品，进而使物品能被抽气至接近真空，抽气效果达到最优效果。整个抽气流程非常的智能化，既能够降低了气泵的消耗，达到优质的抽气效果，还能够智能化完成抽气工作。
需要说明的是，根据上述抽气功能的介绍，本公开的气泵具有能够自动切换的2种吸气模式：常规吸气模式和高压吸气模式。控制器根据压力传感器50检测的吸气压力来控制电磁阀40，进而在上述2种吸气模式之间进行切换。
当常规吸气模式被选择时，电磁阀40被切换至第一状态。当气泵在常规吸气模式下运行时，大部分气流流向如图2所示(气流流向参见箭头方向)，还有小部分气流流向如图3所示(气流流向参见箭头方向)。此时，吸力的主要来源是散热风扇的转动。常规吸气模式一般用于吸气总量较大，吸气压力较小的情况，一般是在气泵100刚开始抽气时运行。当高压吸气模式被选择时，电磁阀40被切换至第二状态。当气泵在高压吸气模式运行时，气流流向如图3所示。此时，吸力的主要来源是气缸的自吸力，其中，最大吸气压力可达10MPa，这远超市面上的真空泵压力。高压吸气模式一般用于吸气总量较少，吸气压力较大的情况，一般是在抽气一段时间后且吸气压力较大时运行。
在气泵100运行时，控制器可以根据压力传感器50的检测到的吸气压力来控制电磁阀40从第一状态切换至第二状态，由此使气泵100能够从常规吸气模式转换至高压吸气模式，以使气泵的操作更智能化。在有适合的使用需求的情况下，控制器也可以根据压力 传感器50的检测到的吸气压力来控制电磁阀40从第二状态切换至第一状态，由此使气泵100能够从常规吸气模式高压吸气模式转换至常规吸气模式。
可选地，外壳10内部形成有过渡腔13，过渡腔13与抽气口11连通。此外，过渡腔13还通过通风孔14与散热风道12的进气端12a相连通。电磁阀40可以设置在通风孔14处。电磁阀40通过打开或者关闭通风孔14可以控制散热风道12的进气端12a与抽气口11的连通和隔断。
可见，过渡腔13的作用首先是配合电磁阀40工作，以控制散热风道12的进气端12a与抽气口11的连通和隔断。过渡腔13的另一作用是对进入的空气进行缓冲，防止空气进入后由于某侧负压较大导致空气分配不均。过渡腔13至少具有两种功用，大大简化了气泵100内部的结构。
可选地，为了保证气缸20的吸气压力不受影响，外壳10内部形成有吸气腔15。如图3和图4所示，吸气腔15与过渡腔13连通；气缸20的吸气口21位于吸气腔15内。吸气腔15保证气缸20的吸气压力不受影响。气泵还包括驱动件、传动组件和活塞杆。传动组件与传动组件驱动连接，传动组件与所述活塞杆驱动连接，活塞杆设置在气缸20内。驱动件驱动传动组件转动以驱使活塞在气缸20内作往复运动。优选地，传动组件、活塞位于吸气腔15内。该结构设置不仅使得气泵的结构更合理、体型更小，而且空气也不会从传动组件以及活塞杆的位置处泄露，气密性更好。
为了进一步保证吸气腔的气密性，在本实施例中，结合图2和图3所示，气泵还包括气缸密封件60，气缸密封件60设置在外壳10的内部，气缸密封件60与外壳10的壳板之间形成吸气腔15。如图2和图5所示，气缸密封件60的结构形状与气缸20适配，同时气缸密封件60的结构形状与外壳10的壳板相互配合，达到密封的作用。
在根据本公开的一个实施例中，气泵100可以具有2种手动的或依据指令信息而切换的吸气模式：常规吸气模式、高压吸气模式。控制器接收来自用户的或压力传感器的指令信息后，选择上述两个模式的任一个以进行吸气控制。选择常规吸气模式时，电磁阀40会被切换至第一状态。当启动气泵时，大部分气流流向如图2所示(气流流向参见箭头方向)，还有小部分气流流向如图3所示(气流流向参见箭头方向)。此时，吸力的主要来源是散热风扇的转动。常规吸气模式一般用于吸气总量较大，吸气压力较小的情况。选择高压吸气模式时，电磁阀40会被切换至第二状态。当启动气泵时，气流流向如图3所示。此时，吸力的主要来源是气缸的自吸力，其中，最大吸气压力可达10MPa，远超市面上的真空泵压力。高压吸气模式一般用于吸气总量较少，吸气压力较大的情况。
为了提升散热效果，在本实施例中，气缸20的至少部分结构位于散热风道12内。散 热风道12的出气端12b设置在外壳10上，散热风扇30驱动气流由散热风道12的进气端12a流向出气端12b。散热风道12将气缸20做功产生的热量通过空气从外壳内部带出，进而达到散热的目的。
结合图3和图4，外壳10上设置有充气口16，气缸20的排气口22与充气口16连通。充气口16为充气功能的结构，通过外接气管进入待充气的物体。此外，气泵中的电池、气缸等具体结构，均可采用现有技术，此处不再赘述。
根据本公开的实施例，提供了一种气泵100的控制方法，如图6所示，气泵为上述实施例的气泵，控制方法包括：
步骤S10：接收指令信息；
步骤S20：根据指令信息，控制电磁阀。
电磁阀通过控制气泵的散热风道与抽气口的连通和隔断，可以控制抽气口11的吸气压力，选择是气缸进行抽气，还是气缸和散热风扇共同进行抽气。本控制方法能够根据用户的选择或者实际需要，手动或自动改变气泵的吸气压力，以实现智能化吸气。
优选地，指令信息可以为提前预设的抽气模式，抽气模式包含了气泵的抽气时间、压力参数、间隔时间等。在本实施例中，根据指令信息，控制电磁阀的步骤(步骤S20)包括：
如果指令信息为第一抽气模式，则控制电磁阀切换至第一状态；
如果指令信息为第二抽气模式，则控制电磁阀切换至第二状态。
第一抽气模式为常规吸气模式，吸气总量较大但吸气压力较小，具体设定可以根据气泵功率选择。第二抽气模式为高压吸气模式，吸气总量较小但吸气压力较大，具体设定可以根据气泵功率选择。
指令信息也可以是压力值，比如在气泵的显示屏或者按键上提供压力输入选项，如果用户直接输入的是压力值，控制方法也可以根据压力值进行判断，并选择最佳的抽气方式。本实施例优选地，指令信息包括压力值；根据指令信息，控制电磁阀的步骤(步骤S20)包括以下步骤：
判断指令信息中的压力值是否大于预设值；
如果是，则控制电磁阀切换至第二状态；
如果否，则控制电磁阀切换至第一状态。
当用户需要的抽气压力值较大(即大于预设值)时，控制气泵切换至第二状态。当用户需要的抽气压力值较小(即小于预设值)时，控制气泵切换至第一状态。本实施例的控制方法能够根据压力值选择最佳的抽气方式，这更加智能化。
指令信息也可以是来自于如前所述的压力传感器50的检测值。下面以压力传感器50的检测值为指令信息来详细描述气泵100的控制方法。如图7所示，根据本公开的一个实施例，提供了一种气泵的控制方法，气泵例如为上述实施例的具有压力传感器50的气泵100，控制方法包括：
步骤S11：获取气缸的吸气压力。例如，吸气压力可以是压力传感器50测量的气缸20的吸气压力。
步骤S21：判断吸气压力是否小于第一预设值。
如果是，则执行步骤S31：控制电磁阀切换至第一状态。
如果否，则执行步骤S32：控制电磁阀切换至第二状态。
在上述实施例中，根据诸如压力传感器检测的气缸的吸气压力来判断是否达到切换的条件，来控制电磁阀，以切换气泵的抽气压力。在气泵吸气时，当判断气缸的吸气压力小于第一预定值时，说明被抽气的物品内部的空气有很多，因此控制电磁阀被切换至第一状态，以利用散热风扇进行抽气。当电磁阀被切换至第一状态之后，吸力的主要来源是散热风扇的转动，吸气总量较大，吸气压力较小。当判断气缸的吸气压力大于第一预设值时，说明被抽气的物品内部的空气被抽走了很多，被抽气的物品发生形变，导致气泵抽取空气的阻力变大，由此使气缸的吸气压力变大，进而控制电磁阀切换至第二状态。当电磁阀被切换至第二状态之后，通过气缸来进行抽气，吸力的主要来源是气缸的自吸力，此时吸气总量较少，吸气压力较大，适用于接近抽真空的物品，进而使物品能被抽气至接近真空，抽气效果达到最优效果。通过上述控制方法，整个抽气流程非常的智能化，既能够降低了气泵的消耗，达到优质的抽气效果，还能够智能化完成抽气工作。
可选地，第一预设值为50kPa。50kPa的数值是本公开根据气泵的体积以及散热风扇最大达到的吸气压力进行设定的。散热风扇的转动能够形成的最大吸气压力只能达到50kPa，所以，当吸气压力达到50kPa时，散热风扇的转动已经无法吸气了，必须更换至高压的吸气模式才能继续吸气，即运行气缸进行吸气。相比之下，气缸的最大吸气压力能够达到10MPa。
可选地，在获取气缸的吸气压力的步骤后，还可以包括以下步骤：如果吸气压力大于第二预设值，则控制气泵关闭。
当被抽气物体较硬时，其在吸气过程中产生形变较少，压力变化较均匀，因此设定第二预设值。在此情形下，如果吸气压力大于第二预设值，说明已完成抽真空，因此关闭气泵。这样，不仅可以智能化的完成抽气功能，自动运行和启动，还可防止由于吸气压力过高使被抽气物体破裂，同时能够保护气泵。
在根据本公开的一个实施例中，第二预设值为10MPa。10MPa的数值既能够判定抽真空程度，还能保护气泵的气缸，防止气缸过载导致损坏。
优选地，在获取气缸的吸气压力的步骤后，还可以包括以下步骤：
获取吸气压力在预设时间内的升高速度值；
判断升高速度值是否大于预设速度值；
如果是，则控制气泵关闭。
当被抽气物体较软时(真空袋)，其在抽气过程中会产生很大的形变，当内部空气被抽干后，由于无法继续形变，压力在短时间内会急剧升高，所以同样可以设定预设速度值。如果判断出压力的升高速度值大于预设速度值，此时即可认为已完成抽真空，因此关闭气泵，这可防止由于吸气压力过高使被抽气物体破裂，同时能够保护气泵。
需要说明的是，获取吸气压力在预定时间内的升高速度值的这个步骤，即可以在步骤S11之后执行，也可以与步骤S11同步执行。获取吸气压力在预定时间内的升高速度值的这个步骤，不仅能够判断被抽气物品的状态，还能在气泵抽气遇到障碍物或者阻挡时，防止气泵持续抽气而损坏气缸的情况发生。
可选地，预设速度值为1MPa/s。本公开不限于此，预设速度值可以根据气泵的体积和气缸的功率进行设定。
根据本公开的实施例，提供了一种计算机可读存储介质，其上存储有计算机程序，程序被处理器执行时实现如上述的方法。
