Description

自动排水阀、电池及用电装置
本申请要求于2022年3月4日提交的名称为“自动排水阀、电池及用电装置”的中国专利申请202220472166.3的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电池领域，尤其涉及一种自动排水阀、电池及用电装置。
 背景技术
节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。
但是，目前的电池在进水后或者电池内的冷却液泄露后，水/冷却液无法自动排出，导致电池存在使用危险。
 技术问题
本申请解决水/冷却液无法自动排出所导致的电池存在使用危险的问题。
 技术解决方案
第一方面，本申请提供了一种自动排水阀，自动排水阀包括：阀体和水溶组件，阀体设置有封闭腔室和分别连通封闭腔室的第一开口和第二开口，阀体穿设于排水口并封闭排水口，第一开口位于排水口内侧，第二开口自排水口露出，水溶组件设置于封闭腔室内，水溶组件封闭第二开口，水溶组件中的水溶件遇水溶解后，水溶组件打开第二开口。
在一些实施例中，水溶组件包括：密封垫和弹性件，密封垫覆盖第二开口，弹性件的两端分别连接阀体内壁和密封垫，水溶件的两端分别抵接阀体内壁和密封垫，且弹性件在水溶件的支撑下呈拉伸状态。通过密封垫、弹性件及水溶件的配合能够封闭第二开口，也能够在水溶件溶解后打开第二开口，同时在水溶件溶解后能够添加水溶件后继续使用，从而能够提升自动排水阀的使用寿命。
在一些实施例中，阀体内设置有导向管，导向管的一端与阀体内壁对应第二开口的位置连接，另一端向第二开口的方向延伸，弹性件设置于导向管内。弹性件设置于导向管内，从而能够对弹性件进行保护。比如：防止采用金属材质制作而成的弹性件接触水/冷却液而导致的生锈，甚至弹性失效。
在一些实施例中，水溶组件还包括：支撑件，支撑件为采用吸水材料制作的柔性件，支撑件沿导向管的周侧设置一圈，支撑件分别抵接密封垫和阀体正对密封垫的内壁，支撑件开设有第一通孔，水溶件设置于支撑件和导向管之间。其一，支撑件位于水溶件的外侧，由此使得箱体内所存在的少量的水汽/水/冷却液被支撑件吸收，从而能够防止少量的水汽/水/冷却液溶解水溶件，由此以能够延长自动排水阀的使用寿命。其二，在水/冷却液排出一段时间后，支撑件恢复原状，以使密封垫封闭第二开口，从而使得电池能够在短时间内继续使用。
在一些实施例中，支撑件包括：第一支撑部和第二支撑部，第一支撑部和第二支撑部均为环状，第二支撑部穿设于第一支撑部内，第一支撑部的一端和第二支撑部的一端连接，第一支撑部和第二支撑部分别开设有第二通孔和第三通孔，第一支撑部和第二支撑部之间及第二支撑部和导向管之间分别设置有水溶件。当少量的水/冷却液进入封闭腔室，将无法打开第二开口，从而能够延长自动排水阀的使用寿命。
在一些实施例中，密封垫朝向第二开口的一侧凸起有凸部，凸部套设有第一密封圈，第一密封圈抵接阀体内壁；或，密封垫朝向第二开口的一侧凹陷有一圈凹部，凹部内设置有第二密封圈，第二密封圈抵接阀体内壁。通过第一密封圈和第二密封圈能够确保阀体在常态下的密封。
在一些实施例中，阀体包括：一圈侧板、底板和顶盖，底板和顶盖分别封闭一圈侧板两端的两个开口，底板、一圈侧板和顶盖配合限定出封闭腔室，底板的径向尺寸大于排水口的孔径，一圈侧板的外轮廓的尺寸小于或等于排水口的孔径，顶盖或一圈侧板开设有第一开口，底板开设有第二开口。阀体的结构简单，便于制作。
在一些实施例中，自动排水阀还可以包括：第三密封圈，第三密封圈固定于底板朝向顶盖的一侧，第三密封圈绕一圈侧板一周，且第三密封圈自底板表面凸起。由此能够确保自动排水阀在常态下的密封。
第二方面，本申请提供了一种电池，电池包括：箱体和以上任一项的自动排水阀，箱体开设有连通箱体内外侧的排水口，自动排水阀的阀体穿设于排水口并封闭排水口，自动排水阀和排水口固定连接。通过将自动排水阀设置于电池的箱体上的排水口，由此能够在箱体内意外进水或者箱体内的冷却液泄露后自动排出水/冷却液，从而能够减少电池的使用危险。
第三方面，本申请提供了一种用电装置，用电装置包括：以上任一项的电池。通过将电池设置于用电装置中，而电池的使用安全提升，由此能够提升用电装置的使用安全。

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源***，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
本发明人注意到，电池在进水后或者电池内的冷却液泄露后，水/冷却液无法自动排出，导致电池存在使用危险。这里，使用危险可能是电池内的水/冷却液连通电池内的电路所导致的电池短路，也可能是电池的***，还可能是其他危险情形。
为了缓解电池在进水后或者电池内的冷却液泄露后，水/冷却液无法自动排出的问题，申请人研究发现，可以在电池的排水口设置自动排水阀。当电池内进水后或者电池内的冷却液泄露后，水/冷却液能够经由自动排水阀自动排出，由此能够提升电池的使用安全。
基于以上考虑，为了缓解电池在进水后或者电池内的冷却液泄露后，水/冷却液无法自动排出的问题，发明人经过深入研究，设计了一种自动排水阀，自动排水阀穿设于电池的排水口并封闭排水口，自动排水阀设置有连通电池内外的通道，通道内设置有水溶件，水溶件堵塞通道，当水/冷却液进入通道并接触通道内的水溶件后，水溶件溶解以使通道畅通，从而使得水/冷却液能够自通道排出至电池外。

排水口201开设于具有容纳腔室的保护壳上，此处的保护壳可以是电池10的箱体2，也可以是电子设备的外壳，还可以是医疗器械等其他设备的外壳，而自动排水阀1能够装配于排水口201并封闭排水口201。当保护壳是电池10的箱体2时，参照图12和图13，箱体2内可以设置有电池单体202，而箱体2上还可以设置有极耳、防爆阀等功能性结构；当保护壳是电子设备的外壳时，保护壳的容纳腔室内设置有电路板、电子元件等结构；当保护壳是医疗器械的外壳时，保护壳的容纳腔室内设置有医疗器械等结构。为了更清楚的说明本申请的方案，以下实施例以保护壳为电池10的箱体2为例进行说明。
自动排水阀1在封闭排水口201后与箱体2固定连接，以防止自动排水阀1自行脱离排水口201，固定连接方式可以是螺接、卡接等形式。示例性地：参照图5，自动排水阀1的阀体11的径向尺寸等于排水口201的孔径，当阀体11穿设于排水口201后能够封闭排水口201，同时阀体11和排水口201处的箱体2之间通过螺钉连接以防止自动排水阀1自行脱离排水口201。
阀体11设置有封闭腔室111和分别连通封闭腔室111的第一开口112和第二开口113，当阀体11穿设于排水口201并封闭排水口201时，第一开口112位于排水口201内侧，第二开口113自排水口201露出，也就是说，当阀体11穿设于排水口201并封闭排水口201时，第一开口112、封闭腔室111及第二开口113形成连通箱体2内外的通道，而水/冷却液能够进入该通道并排出至箱体2外侧。封闭腔室111的形状可以是长方体形状，也可以是球体形状，还可以是其他形状。
第一开口112和第二开口113的形状可以是圆形，也可以是正方形，还可以是其他形状。第二开口113的形状可以与第一开口112的形状相同，也可以不同。第二开口113的孔径可以是小于第一开口112的孔径，也可以是等于第一开口112的孔径，还可以是大于第一开口112的孔径。比如：第二开口113的形状和第一开口112的形状相同，但第二开口113的孔径大于第一开口112的孔径，那么，箱体2内的水/冷却液经由第一开口112进入封闭腔室111后，能够快速的经由第二开口113流出，从而能够防止由于封闭腔室111内充满水/冷却液所导致的箱体2内的水/冷却液的堆积，甚至向箱体2内倒流的情形。第一开口112的数量可以是多个，当第一开口112的数量为多个时，多个第一开口112可以均匀的分布于阀体11上。
这里，第一开口112可以与箱体2内侧底部表面之间具有一定高度，防止因少量冷凝水聚集而使水溶件121溶解，仅当箱体2内的积水到达一定量时才开启排水。由此能够延长自动排水阀1的使用寿命。
水溶组件12设置于封闭腔室111内，水溶组件12封闭第二开口113，也就是说，水溶组件12位于通道内并堵塞通道，而在水溶组件12中的水溶件121遇水/冷却液溶解后，水溶组件12打开第二开口113 ，即在水溶组件12中的水溶件121遇水/冷却液溶解后，通道畅通，箱体2内的水/冷却液能够经由第一开口112、封闭腔室111及第二开口113排出至箱体2外侧。水溶件121的初始状态为固态并封闭第二开口113，遇水/冷却液后溶解。水溶件121可以是采用聚乙烯醇、羧甲基纤维素钠或聚乙烯吡咯烷酮等材料制作而成的。
本实施例中，自动排水阀1的阀体11穿设于箱体2上所开设的排水口201并封闭排水口201，阀体11的第一开口112、封闭腔室111及第二开口113配合形成连通箱体2内外侧的通道，水溶组件12设置于通道内并堵塞该通道，当箱体2内的水/冷却液经由第一开口112进入通道并接触水溶组件12的水溶件121后，水溶件121溶解且通道畅通，从而使得水/冷却液能够经由第二开口113排出，由此能够减少电池10所存在的使用危险。
具体实施时，其一，可通过设置检测装置以实时检测第二开口113是否有水/冷却液排出，当检测到有水/冷却液排出时，工作人员可以及时的对自动排水阀1进行维修或者更换，以确保电池10的继续使用；其二，自动排水阀1装配于箱体2上后满足IPX8密封等级要求。
根据本申请的一些实施例，参照图6和图7，水溶组件12包括：密封垫122和弹性件123，密封垫122覆盖第二开口113，弹性件123的两端分别连接阀体11内壁和密封垫122，水溶件121的两端分别抵接阀体11内壁和密封垫122，且弹性件123在水溶件121的支撑下呈拉伸状态。
密封垫122覆盖第二开口113后即能够对第二开口113进行封闭，从而使得封闭腔室111和第二开口113之间由于密封垫122的阻挡而不连通。密封垫122朝向第二开口113的尺寸大于第二开口113的孔径，以使密封垫122能够覆盖第二开口113。密封垫122的形状可以与第二开口113的形状相同，也可以不同。密封垫122可以是采用弹性材料制作而成的，比如：硅胶材料、橡胶材料等。
弹性件123的两端分别连接阀体11内壁和密封垫122，这里的阀体11内壁和密封垫122彼此相对，由此弹性件123能够在阀体11内壁和密封垫122连线方向上拉伸或者缩短。弹性件123可以是弹簧，也可以是硅胶、橡胶等材料制作而成的弹性件。弹性件123在水溶件121的支撑下呈拉伸状态，即初始状态下，弹性件123有一定的拉伸量。
密封垫122覆盖第二开口113，弹性件123的两端分别连接阀体11内壁和密封垫122，水溶件121的两端分别抵接阀体11内壁和密封垫122，且弹性件123在水溶件121的支撑下呈拉伸状态，由此，当具有支撑作用的水溶件121遇水/冷却液溶解后，弹性件123复位收缩，使得密封垫122远离第二开口113，从而能够打开第二开口113以使封闭腔室111内的水/冷却液能够自第二开口113排出。
本实施例中，通过密封垫122、弹性件123及水溶件121的配合能够封闭第二开口113，也能够在水溶件121溶解后打开第二开口113，同时在水溶件121溶解后能够添加水溶件121后继续使用，从而能够提升自动排水阀1的使用寿命。
根据本申请的一些实施例，参照图7，阀体11内设置有导向管114，导向管114的一端与阀体11内壁对应第二开口113的位置连接，另一端向第二开口113的方向延伸，弹性件123设置于导向管114内。
当弹性件120为非金属材料制作而成时，导向管114的管壁可以开设有连通导向管114内外表面的减重孔，由此能够减少导向管114的重量，同时能够减少导向管114的制作成本。导向管114靠近第二开口113的一端与密封垫122间隔开，以能够为密封垫122打开第二开口113提供空间。
本实施例中，弹性件123设置于导向管114内，从而能够对弹性件123进行保护。比如：防止采用金属材质制作而成的弹性件123接触水/冷却液而导致的生锈，甚至弹性失效。
根据本申请的一些实施例，参照图6至图11，水溶组件12还包括：支撑件124，支撑件124为采用吸水材料制作的柔性件，支撑件124沿导向管114的周侧设置一圈，支撑件124分别抵接密封垫122和阀体11正对密封垫122的内壁，支撑件124开设有第一通孔，水溶件121设置于支撑件124和导向管114之间。
支撑件124为采用吸水材料制作的柔性件，即其在吸收水/冷却液后能够变形，且在其上的水/冷却液流失后能够恢复原状，比如：支撑件124采用高吸水性树脂材料制作而成。支撑件124沿导向管114的周侧设置一圈，也就是说，支撑件124为环状结构，且支撑件124套设于导向管114外侧。
使用时，水/冷却液自第一开口112进入封闭腔室111后，部分被支撑件124吸收，吸收水/冷却液后的支撑件124在弹性件123的复位作用下溃缩变形，部分经由支撑件124上的第一通孔进入到支撑件124和导向管114之间并与支撑件124和导向管114之间的水溶件121接触，水溶件121遇水/冷却液溶解，由此密封垫122打开第二开口113。
本实施例中，其一，支撑件124位于水溶件121的外侧，由此使得箱体2内所存在的少量的水汽/水/冷却液被支撑件124吸收，从而能够防止少量的水汽/水/冷却液溶解水溶件121，由此以能够延长自动排水阀1的使用寿命。其二，在水/冷却液排出一段时间后，支撑件124恢复原状，以使密封垫122封闭第二开口113，从而使得电池10能够在短时间内继续使用。
这里，纵然支撑件124恢复原状以使电池10能够在短时间内继续使用，工作人员也应在较短时间内进行自动排水阀1的维修或更换，以确保电池10的使用安全。
根据本申请的一些实施例，参照图8至11，支撑件124包括：第一支撑部1241和第二支撑部1242，第一支撑部1241和第二支撑部1242均为环状，第二支撑部1242穿设于第一支撑部1241内，第一支撑部1241的一端和第二支撑部1242的一端连接，第一支撑部1241和第二支撑部1242分别开设有第二通孔1243和第三通孔1244，第一支撑部1241和第二支撑部1242之间及第二支撑部1242和导向管114之间分别设置有水溶件121。
第一支撑部1241和第二支撑部1242均为环状，第二支撑部1242穿设于第一支撑部1241内，第一支撑部1241的一端和第二支撑部1242的一端连接，这里，当环形的第二支撑部1242位于环形的第一支撑部1241内，且环形第一支撑部1241的一端和环形第二支撑部1242的一端连接，使得第一支撑部1241和第二支撑部1242限定出环形凹槽，而导向管114穿设于第二支撑部1242内并与第二支撑部1242之间具有间隙，同时第一支撑部1241和第二支撑部1242分别开设有第二通孔1243和第三通孔1244，由此使得第一支撑部1241和第二支撑部1242之间的环形凹槽、第二支撑部1242和导向管114之间的间隙均能够分别设置水溶件121。
第一支撑部1241和第二支撑部1242之间的环形凹槽内可以镶嵌有多个水溶件121，且多个水溶件121绕第二支支撑部1242靠近第一支撑部1241的环向表面均匀设置。同样地，第二支撑部1242和导向管114之间的间隙可以设置有多个水溶件121，且多个水溶件121绕导向管114靠近第二支撑部1242的环向表面均匀设置。
使用时，当大量的水/冷却液进入封闭腔室111并依次接触第一支撑部1241、第一支撑部1241和第二支撑部1242之间的水溶件121、第二支撑部1242、第二支撑部1242和导向管114之间的水溶件121后，在弹性件123的复位作用下第一支撑部1241和第二支撑部1242溃缩变形，且第一支撑部1241和第二支撑部1242之间的水溶件121及第二支撑部1242和导向管114之间的水溶件121溶解，能够密封垫122打开第二开口113；当少量的水/冷却液进入封闭腔室111，将无法打开第二开口113。
本实施例中，当少量的水/冷却液进入封闭腔室111，将无法打开第二开口113，从而能够延长自动排水阀1的使用寿命。
根据本申请的一些实施例，参照图7，密封垫122朝向第二开口113的一侧凸起有凸部1221，凸部1221套设有第一密封圈1222，第一密封圈1222抵接阀体11内壁；或，密封垫122朝向第二开口113的一侧凹陷有一圈凹部，凹部内设置有第二密封圈，第二密封圈抵接阀体11内壁。
第一密封圈1222可以是采用橡胶材质、硅胶材质等制作而成的弹性件。第二密封圈可以是采用橡胶材质、硅胶材质等制作而成的弹性件。当密封垫122朝向第二开口113的一侧凹陷有一圈凹部，凹部内设置有第二密封圈，第二密封圈抵接阀体11内壁时，第二密封圈突出于一圈凹部的开口并抵接阀体11。
本实施例中，第一密封圈1222和第二密封圈能够确保阀体11在常态下的密封。
根据本申请的一些实施例，参照图2至图4，阀体11包括：一圈侧板115、底板116和顶盖117，底板116和顶盖117分别封闭一圈侧板115两端的两个开口，底板116、一圈侧板115和顶盖117配合限定出封闭腔室111，底板116的径向尺寸大于排水口201的孔径，一圈侧板115的外轮廓的尺寸小于或等于排水口201的孔径，顶盖117或一圈侧板115开设有第一开口112，底板116开设有第二开口113。
一圈侧板115的外轮廓的尺寸小于或等于排水口201的孔径，使得一圈侧板115能够穿设于排水口201。底板116的径向尺寸大于排水口201的孔径，使得一圈侧板115穿设于排水口201后，底板116能够抵接箱体2的外表面并覆盖排水口201。顶盖117或一圈侧板115开设有第一开口112，具体实施时，由于水/冷却液在重力的作用下位于箱体2的下端，为此可以根据与地面之间的最短距离原则设置第一开口112的位置，比如：自动排水阀1设置于箱体2的底部上所设置的排水后201，那么，一圈侧板115与地面之间的距离比顶盖117与地面之间的距离小，为此，第一开口112可以设置在一圈侧板115，而又由于一圈侧板115下端的区域与地面之间的距离比上端的区域与地面之间的距离小，为此，第一开口112可以设置在一圈侧板115下端的区域。
本实施例中，阀体11的结构简单，便于制作。
根据本申请的一些实施例，参照图1、图2及图5-图7，自动排水阀1还可以包括：第三密封圈13，第三密封圈13固定于底板116朝向顶盖117的一侧，第三密封圈13绕一圈侧板115一周，且第三密封圈13自底板116表面凸起。
当自动排水阀1装配于箱体2后，第三密封圈13被挤压于箱体2外表面和底板116之间，由此能够确保自动排水阀1在常态下的密封。
根据本申请的一些实施例，参照图12和图13，本申请还提供了一种电池10，电池10包括：箱体2和以上任一方案所述的自动排水阀11，箱体2开设有连通箱体2内外侧的排水口201，自动排水阀1的阀体11穿设于排水口201并封闭排水口201，自动排水阀1和排水口201固定连接。
