Description

真空棒 技术领域
本实用新型涉及抽真空装置技术领域，具体涉及一种真空棒。
背景技术
真空棒是生活中用于抽真空的装置，例如对压缩袋进行抽真空；目前市面上的真空棒一般包括壳体、安装在壳体内部的支架和安装在壳体开口端的接头组件，支架上安装有真空泵和电路板，电路板上安装有负压传感器，真空泵的抽气口和负压传感器的检测端均与接头组件的内腔连通，但由于目前市面上的真空棒中的真空泵的抽气口和负压传感器的检测端均通过独立的结构与接头组件的内腔连通，这样一来，在负压传感器检测真空泵的抽气口的负压值时，存在负压传感器对真空泵的抽气口的负压值检测准确度低的缺点。
实用新型内容
针对现有技术的不足，本实用新型提供一种真空棒，其内部的接头组件的内腔、负压传感器的检测端和真空泵的抽气口通过三通接头连通，即负压传感器的检测端直接与真空泵的抽气口连通，这样一来，能够提高负压传感器对真空泵的抽气口的负压值的检测准确度。
本实用新型的真空棒，包括壳体、安装在壳体内部的支架和安装在壳体开口端的接头组件，支架上安装有真空泵，壳体中安装有蓄电池和电路板，真空泵和蓄电池均与电路板电连接，壳体上安装有用于触发位于电路板上的按键以控制真空泵启停的按钮，电路板上安装有负压传感器，真空棒还包括三通接头，接头组件的内腔与三通接头的第一端连通，负压传感器的检测端与三通接头的第二端连通，真空泵的抽气口与三通接头的第三端连通。
本实用新型的真空棒，其中，电路板上安装有若干个沿竖直方向分布的灯珠，壳体中嵌装有与灯珠相同数量的导光柱，每个导光柱分别与其中一个灯珠对应设置；通过灯珠的设置，灯珠能够指示真空棒的工作状态，例如，真空棒在刚开启时，所有灯珠均处于被点亮的状态，当真空泵在对收纳袋抽真空的过程中，如负压传感器检测到真空泵的抽气口的气压值逐渐减小时，即收纳袋中的气压逐渐减小时，灯珠会由下至上逐个熄灭，当收纳袋被完全抽真空后，所有的灯珠均能够熄灭且真空棒会停止工作；另外，在真空棒充电时，若干个灯珠能够通过亮灭状态的变化来实时显示蓄电池中的电量(例如，灯珠有5个，当蓄电池中的电量达到20％的蓄电池容量时，位于最下方的一个灯珠被点亮，当蓄电池中的电量达到40％的蓄电池容量时，位于最下方的两个灯珠被点亮，依次类推，当蓄电池中的电量达到100％的蓄电池容量时，所有灯珠都被点亮)，当蓄电池充满电后，所有的灯珠均能够被点亮。
本实用新型的真空棒，其中，位于灯珠所在位置处的电路板上连接有遮光垫，遮光垫中设置有与灯珠相同数量的且用于避让灯珠的避让孔，每个避让孔分别与其中一个灯珠对应设置；通过遮光垫的设置，在其中一个灯珠被点亮时，能够避免该灯珠发出的光影响到 与该灯珠相邻的灯珠和导光柱。
本实用新型的真空棒，其中，支架上设置有开口槽，真空泵嵌装在开口槽中，位于开口槽两侧的支架上均设置有抱紧块，真空泵通过抱紧块压紧在开口槽中；通过在支架上设置开口槽，且位于开口槽两侧的支架上均设置有用于压紧真空泵的抱紧块，这样一来，真空泵能够方便地被嵌装在支架上，即能够给真空泵与支架的装配带来方便，此外，由于抱紧块实现了对真空泵的压紧，这样一来，支架只需要采用现有真空棒中一半的支架即可，从而能够达到节省材料成本，降低生产成本的目的。
本实用新型的真空棒，其中，支架的外壁上设置有定位插槽，壳体的内壁上设置有定位插条，支架安装到壳体中后，定位插条与定位插槽配合插接；通过定位插条和定位插槽的设置，在支架安装到壳体中后，支架上的定位插槽能够与壳体内壁上的定位插条配合插接，从而能够使得支架与壳体之间实现周向限位的功能。
本实用新型的真空棒，其中，接头组件包括安装在壳体开口端的抽气接头，抽气接头的上端套装有密封套，位于抽气接头内部的密封套的底面上设置有若干个吸气孔，抽气接头的底部设置有与抽气接头的内腔连通的抽气管，抽气管与三通接头的第一端配合插接并密封；通过采用这种接头组件后，在使用真空棒对收纳袋进行抽真空时，抽气接头能够与收纳袋上的抽气嘴配合插接，密封套能够实现对抽气接头与收纳袋上的抽气嘴之间的密封，当真空泵工作时，在三通接头和接头组件的作用下，本实用新型即可实现对收纳袋的抽真空(在接头组件对收纳袋进行抽真空的过程中，来自收纳袋的空气能够流经位于密封套上的吸气孔)；此外，通过抽气管的设置，抽气接头能够可靠地与三通接头密封连接在一起。
本实用新型的真空棒，其中，负压传感器的检测端通过连接管与三通接头的第二端连通，真空泵的抽气口与三通接头的第三端配合插接并密封；通过连接管的设置，负压传感器的检测端能够通过连接管可靠地与三通接头密封连接在一起；通过采用这种结构后，真空泵的抽气口能够可靠地与三通接头密封连接在一起。
本实用新型的真空棒，其中，蓄电池嵌装在支架上，电路板卡装在支架上，按钮嵌装在壳体的侧壁上；通过采用这种结构后，蓄电池和电路板能够方便地被安装在支架上，按钮能够被方便地安装在壳体的侧壁上。
本实用新型的真空棒，其中，电路板上安装有充电接口，位于充电接口所在位置处的壳体上设置有通孔，通孔用于供充电线的插头穿过以使充电线的插头与充电接口配合插接；通过充电接口的设置，在蓄电池没电时，可通过充电线与充电接口的连接来实现对蓄电池的充电。
本实用新型的真空棒，其中，壳体的外部套装有透明套，壳体的下端嵌装有装饰圈，装饰圈的内部嵌装有嵌块，嵌块的底面上印刷有标识，透明套的下端设置有用于避让装饰圈的让位孔；通过透明套的设置，当采用具有色彩的壳体时，壳体的色彩能够通过透明套透出，这样一来，能够使得真空棒的分色更有层次感，提高真空棒的美观度，且能够使得真空棒的外表面更为光滑、平整、没有接缝；另外，通过装饰圈的设置，能够提高真空棒的美观度；此外，印刷在嵌块底面上的标识可以是真空棒的LOGO、真空棒的型号、真空棒的参数等。
本实用新型内部的接头组件的内腔、负压传感器的检测端和真空泵的抽气口通过三通接头连通，即负压传感器的检测端直接与真空泵的抽气口连通，这样一来，能够提高负压传感器对真空泵的抽气口的负压值的检测准确度。

另外，在本实用新型中如涉及“第一”、“第二”等的描述仅用于描述目的，并非特别指称次序或顺位的意思，亦非用以限定本实用新型，其仅仅是为了区别以相同技术用语描述的组件或操作而已，而不能理解为指示或暗示其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”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本实用新型要求的保护范围之内。
本实用新型的真空棒，包括壳体1、安装在壳体1内部的支架2和安装在壳体1开口端的接头组件，支架2上安装有真空泵3，壳体1中安装有蓄电池4和电路板5，真空泵3和蓄电池4均与电路板5电连接，壳体1上安装有用于触发位于电路板5上的按键以控制真空泵3启停的按钮11，电路板5上安装有负压传感器51，真空棒还包括三通接头6，接头组件的内腔与三通接头6的第一端连通，负压传感器51的检测端与三通接头6的第二端连通，真空泵3的抽气口与三通接头6的第三端连通。
电路板5上安装有若干个沿竖直方向分布的灯珠52，壳体1中嵌装有与灯珠52相同数量的导光柱12，每个导光柱12分别与其中一个灯珠52对应设置；通过灯珠的设置，灯珠能够指示真空棒的工作状态，例如，真空棒在刚开启时，所有灯珠均处于被点亮的状态，当真空泵在对收纳袋抽真空的过程中，如负压传感器检测到真空泵的抽气口的气压值逐渐减小时，即收纳袋中的气压逐渐减小时，灯珠会由下至上逐个熄灭，当收纳袋被完全抽真空后，所有的灯珠均能够熄灭且真空棒会停止工作；另外，在真空棒充电时，若干个灯珠能够通过亮灭状态的变化来实时显示蓄电池中的电量(例如，灯珠有5个，当蓄电池中的电量达到20％的蓄电池容量时，位于最下方的一个灯珠被点亮，当蓄电池中的电量达到40％的蓄电 池容量时，位于最下方的两个灯珠被点亮，依次类推，当蓄电池中的电量达到100％的蓄电池容量时，所有灯珠都被点亮)，当蓄电池充满电后，所有的灯珠均能够被点亮。
位于灯珠52所在位置处的电路板5上连接有遮光垫53，遮光垫53中设置有与灯珠52相同数量的且用于避让灯珠52的避让孔531，每个避让孔531分别与其中一个灯珠52对应设置；通过遮光垫的设置，在其中一个灯珠被点亮时，能够避免该灯珠发出的光影响到与该灯珠相邻的灯珠和导光柱。
支架2上设置有开口槽21，真空泵3嵌装在开口槽21中，位于开口槽21两侧的支架2上均设置有抱紧块22，真空泵3通过抱紧块22压紧在开口槽21中；通过在支架上设置开口槽，且位于开口槽两侧的支架上均设置有用于压紧真空泵的抱紧块，这样一来，真空泵能够方便地被嵌装在支架上，即能够给真空泵与支架的装配带来方便，此外，由于抱紧块实现了对真空泵的压紧，这样一来，支架只需要采用现有真空棒中一半的支架即可，从而能够达到节省材料成本，降低生产成本的目的。
支架2的外壁上设置有定位插槽23，壳体1的内壁上设置有定位插条13，支架2安装到壳体1中后，定位插条13与定位插槽23配合插接；通过定位插条和定位插槽的设置，在支架安装到壳体中后，支架上的定位插槽能够与壳体内壁上的定位插条配合插接，从而能够使得支架与壳体之间实现周向限位的功能。
接头组件包括安装在壳体1开口端的抽气接头7，抽气接头7的上端套装有密封套71，位于抽气接头7内部的密封套71的底面上设置有若干个吸气孔711，抽气接头7的底部设置有与抽气接头7的内腔连通的抽气管72，抽气管72与三通接头6的第一端配合插接并密封；通过采用这种接头组件后，在使用真空棒对收纳袋进行抽真空时，抽气接头能够与收纳袋上的抽气嘴配合插接，密封套能够实现对抽气接头与收纳袋上的抽气嘴之间的密封，当真空泵工作时，在三通接头和接头组件的作用下，本实用新型即可实现对收纳袋的抽真空(在接头组件对收纳袋进行抽真空的过程中，来自收纳袋的空气能够流经位于密封套上的吸气孔)；此外，通过抽气管的设置，抽气接头能够可靠地与三通接头密封连接在一起。
负压传感器51的检测端通过连接管511与三通接头6的第二端连通，真空泵3的抽气口与三通接头6的第三端配合插接并密封；通过连接管的设置，负压传感器的检测端能够通过连接管可靠地与三通接头密封连接在一起；通过采用这种结构后，真空泵的抽气口能够可靠地与三通接头密封连接在一起。
蓄电池4嵌装在支架2上，电路板5卡装在支架2上，按钮11嵌装在壳体1的侧壁上；通过采用这种结构后，蓄电池和电路板能够方便地被安装在支架上，按钮能够被方便地安装在壳体的侧壁上。
电路板5上安装有充电接口54，位于充电接口54所在位置处的壳体1上设置有通孔14，通孔14用于供充电线的插头穿过以使充电线的插头与充电接口54配合插接；通过充电接口的设置，在蓄电池没电时，可通过充电线与充电接口的连接来实现对蓄电池的充电。
壳体1的外部套装有透明套8，壳体1的下端嵌装有装饰圈91，装饰圈91的内部嵌装有嵌块92，嵌块92的底面上印刷有标识，透明套8的下端设置有用于避让装饰圈91的让位孔81；通过透明套的设置，当采用具有色彩的壳体时，壳体的色彩能够通过透明套透出，这样一来，能够使得真空棒的分色更有层次感，提高真空棒的美观度，且能够使得真空棒的外表面更为光滑、平整、没有接缝；另外，通过装饰圈的设置，能够提高真空棒的美观度；此外，印 刷在嵌块底面上的标识可以是真空棒的LOGO、真空棒的型号、真空棒的参数等。
在使用本实用新型时，将接头组件与收纳袋的抽气嘴连接，然后按动按钮，按钮被按动后，真空泵即会开始工作，真空泵工作时，本实用新型即可实现对收纳袋的抽真空；在真空泵对收纳袋进行抽真空的过程中，负压传感器能够实时检测真空泵的抽气口的负压值，当负压传感器检测到真空泵的抽气口的负压值达到目标值时(即收纳袋抽真空完成时)，本实用新型即会自动关闭真空泵，从而能够达到对真空泵自动控制的目的。
以上所述仅为本实用新型的实施方式而已，并不用于限制本实用新型。对于本领域技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原理内所作的任何修改、等同替换、改进等，均应包括在本实用新型的权利要求范围之内。
