如图1至图6所示，本发明所述的一种衣物处理设备的自动投放装置，所述自动投放装置包括壳体1和柔性部件2。
所述壳体1内部设置有进水端131和出液端152。
所述柔性部件2设置在所述壳体1的内部。所述柔性部件2将壳体1内部分隔为容纳腔11和吸液腔12。所述容纳腔11与所述进水端131连通；所述吸液腔12与所述出液端152连通；所述吸液腔12用于容置衣物处理剂。
所述柔性部件2在自然状态下具有形变部22。在进水端131进水时，水流挤压所述柔性部件2使所述形变部22产生形变，所述柔性部件2向吸液腔12运动，将衣物处理剂由出液端152排出吸液腔12。
本发明通过将柔性部件2在自然状态下具有形变部22，在进水端131进水时，挤压柔性部件2使所述形变部22产生形变，使柔性部件2向吸液腔12运动，将衣物处理剂由出液端152排出吸液腔12，实现了在低水压的情况下也能将衣物处理剂投放至洗衣机内，解决了现有技术中衣物处理剂无法精准投放的技术问题。
具体地，所述容纳腔11的一端与所述进水端131连通。所述容纳腔11的另一端被所述柔性部件2封堵。
需要解释的是，所述进水端131直接与所述容纳腔11，使通过进水端131进入所述自动投放装置内部的水流直接作用在所述柔性部件2上，从而使所述柔性部件2在低水压的情况下也能向所述吸液腔12运动，使衣物处理剂投放至洗衣机内。本发明的自动投放装置利用控制洗衣机的进水即可实现，改变自动投放原理，更为优化的结构设计，更低的生产制造成本。
所述壳体1内部还设置有进液端151。在进水端131停止进水时，所述形变部22恢复至自然状态，向所述容纳腔11运动，将衣物处理剂由进液端151吸入吸液腔12内。
另外，本发明的衣物处理剂包括但不仅限于洗涤剂、柔顺剂、消毒液、衣物护理剂、芳香剂等。
进一步地，所述柔性部件2还包括覆盖部21，所述覆盖部21设于所述柔性部件2的中部。所述形变部22与所述覆盖部21的外周连接。
本发明通过将所述覆盖部21设于所述柔性部件2的中部，使流入容纳腔11的水流直接作用到覆盖部21上，进一步实现了在低水压的情况下也能将衣物处理剂投放至洗衣机内，解决了现有技术中衣物处理剂无法精准投放的技术问题。
具体地，所述形变部22的弹性变量小于所述覆盖部21的弹性变量。需要解释的是，在所述覆盖部21受到水流的挤压时，由于所述形变部22的弹性变量小于所述覆盖部21的弹性变量，此时，所述形变部22开始产生弹性形变，使所述覆盖部21向所述吸液腔12运动，进而使衣物处理剂投放至洗衣机内。
如图2所示，所述柔性部件2设置在所述吸液腔12内周壁上。
所述吸液腔12的内径大于所述容纳腔11的内径。所述覆盖部21封堵所述容纳腔11和所述吸液腔12的连通口，所述形变部22设于所述连通口的外周。
本发明通过将所述覆盖部21封堵所述容纳腔11和所述吸液腔12的连通口，并将所述形变部22设于所述连通口的外周，进一步使所述柔性部件2在受到较低水压的水流时，也向所述吸液腔12运动，解决了现有技术中衣物处理剂无法精准投放的技术问题。
具体地，所述覆盖部21的外周壁与所述形变部22的内周壁连接。更具体 地，所述形变部22自所述覆盖部21的外周壁向吸液腔12折叠设置。
所述形变部22自所述覆盖部21的外周壁先向所述吸液腔12方向延伸设置，然后弯折向所述容纳腔11方向延伸设置。
一种是实施方式是，所述覆盖部21的内径小于所述容纳腔11的内径，所述覆盖部21封堵所述容纳腔11和所述吸液腔12的连通口上。
另一种是实施方式是，所述覆盖部21的内径大于所述容纳腔11的内径，所述覆盖部21封堵所述容纳腔11和所述吸液腔12的连通口上。
本发明采用的方案是所述覆盖部21的内径大于所述容纳腔11的内径。具体地，所述覆盖部21在自然状态下覆盖所述容纳腔11和所述吸液腔12的连接处。所述形变部22连接于所述覆盖部21和所述吸液腔12的内周壁之间。
本发明通过将所述覆盖部21在自然状态下覆盖所述容纳腔11和所述吸液腔12的连接处，使进入容纳腔11的水全部作用在所述覆盖部21上，进而使所述覆盖部21在受到较低水压的水流时，也向所述吸液腔12运动，解决了现有技术中衣物处理剂无法精准投放的技术问题。
另外，将所述形变部22连接于所述覆盖部21和所述吸液腔12的内周壁之间，一方面，使所述容纳腔11与所述吸液腔12完全隔离；另一方面，使所述形变部22有充分的形变空间，当通入所述进水端131的水流的水压较强时，所述形变部22在所述吸液腔12内部有足够的形变空间。
具体地，所述形变部22向所述吸液腔12方向凸出折叠。
优选地，所述形变部22为多重折叠。
进一步地，所述覆盖部21包括突出结构211和缓冲结构212。
所述突出结构211设置在所述覆盖部21的中部。所述突出结构211的一端 凸出设置伸入所述容纳腔11内，所述突出结构211的用于封堵所述容纳腔11和所述吸液腔12的连通口。
所述缓冲结构212设置在所述覆盖部21的外部。所述缓冲结构212的内周端与所述突出结构211连接，所述缓冲结构212的外周端与所述形变部22连接。
本发明通过将所述突出结构211的一端凸出设置伸入所述容纳腔11内，使所述容纳腔11和所述吸液腔12的连通口被封堵住，进一步使从进水端131进入的水流能够全部作用在所述突出结构211上，进而能够使水流的动能全部转化为所述柔性部件2的弹性势能，达到对能量的充分利用。同时节约了能源，降低了成本，满足了客户的需求。
具体地，所述缓冲结构212的一侧在自然状态下覆盖所述容纳腔11和所述吸液腔12的连接处。
另外，所述柔性部件2还包括固定部23。所述固定部23的弹性系数大于所述形变部22的弹性系数。所述固定部23用于将所述柔性部件2固定在所述第一壳体13得内壁上。

本发明通过所述第一壳体13与第二壳体14将所述固定部23挤压固定在环形密封槽16内，保证了所述容纳腔11与所述吸液腔12之间得密封性，也避免了所述柔性部件2受到压力的作用时，所述形变部22能够在所述吸液腔12内 部运动。
具体地，所述第一壳体13包括第一环形连接边133，所述第二壳体14包括第二环形连接边143。所述第一环形连接边133与第二环形连接边143抵接形成环形密封槽16。
需要说明的是，所述环形密封槽16的体积小于所述固定部23的体积。
更加具体地，所述第一壳体13与所述第二壳体14交接处的内壁向外凹陷形成第一环形连接边133、第三环形连接边134。
所述第二环形连接边143上设有第二凸起144。所述第一环形连接边133与第二凸起144之间有一距离。所述第一环形连接边133、第三环形连接边134、第二环形连接边143与所述第二凸起144形成环形密封槽16。
另一种实施方式是，所述第一壳体13的内周壁上设有限位结构，所述固定部23设置在所述限位结构上。所述限位结构将所述固定部23固定在所述壳体1内部，并且在所述柔性部件2的形变部22在所述壳体1内部运动时，保证了容纳腔11与吸液腔12不会连通。
具体地，所述限位结构包括环形限位筋，所述环形限位筋凸设在所述第一壳体13的内侧壁上。所述固定部23的一端与所述环形限位筋抵接。具体地，所述环形限位筋与所述固定部23相抵接。所述固定部23与所述形变部22的外周壁连接。
还一种实施方式是，所述第一环形连接边133和/或第二环形连接边143上设置环形密封槽16。所述第一环形连接边133和/或第二环形连接边143将所述固定部23挤压固定在环形密封槽16内。
具体地，所述环形密封槽16设置在所述第一环形连接边133和/或第二环 形连接边143上。所述环形密封槽16的体积小于所述固定部23的体积。
又一种实施方式是，所述第一环形连接边133和第二环形连接边143将所述固定部23挤压固定。
另外，所述第一壳体13包括第一环端135、第二环端136，所述第二环端136上设有泄压口，所述泄压端132自所述泄压口向所述第二环端136外部延伸设置；
所述环形密封槽16设于第一壳体13的开口端与所述泄压口之间。
具体地，所述泄压口设置在所述第一环端135与第二环端136的交接处。所述泄压端132具有一定的延伸长度。
如图4所示，所述第二壳体14上设置有抽吸管141和投放管142。所述抽吸管141与衣物处理剂的储存装置连通，用于将所述衣物处理剂的储存装置内部的衣物处理剂吸入吸液腔12中；所述投放管142与所述衣物处理装置内部的投放管142到连通，用于将所述吸液腔12内部的衣物处理剂投放至衣物处理装置中。
所述第一壳体13上还包括泄压端132，所述柔性部件2在自然状态下覆盖泄压端132。所述泄压端132与所述容纳腔11连通。所述形变部22在自然状态下覆盖所述泄压端132。
所述形变部22设于所述连通口的外周，自所述覆盖部21向吸液腔12内凸出折叠沿设置，经过泄压端132，延伸至所述吸液腔12的内周壁。
当进水端131进水时，挤压柔性部件2使所述形变部22产生形变，使柔性部件2向吸液腔12运动，将衣物处理剂由出液端152排出吸液腔12，同时打开泄压端132，水流将排出的衣物处理剂冲入衣物处理装置内。
如图2至3所示，所述自动投放装置还包括保护装置3。所述保护装置3设置在所述吸液腔12内，所述保护装置3与所述柔性部件2连接。所述保护装置3用于在挤压柔性部件2的力降低时，对柔性部件2提供恢复至自然状态的恢复力。
本发明通过将所述保护装置3与所述柔性部件2连接，保证了所述柔性部件2在挤压柔性部件2的力降低时，能够迅速恢复到自然状态，同时也避免了所述柔性部件2在通入所述进水端131的水流的水压较强时，与其他部件发生碰撞而受到损伤，进而影响了所述自动投放装置的使用寿命。
具体地，所述保护装置3一端朝向所述吸液腔12底部设置，所述保护装置3的另一端与所述柔性部件2的缓冲结构212连接。可以理解为，当挤压柔性部件2的力降低时，所述保护装置3对柔性部件2提供恢复至自然状态的恢复力，而带动所述柔性部件2向所述容纳腔11的方向移动，所述缓冲结构212避免了所述保护装置3与壳体1碰撞，而导致保护装置3和/或壳体1损坏的情况。
需要解释的是，所述保护装置3也可以与所述柔性部件2不连接，通过对上述进水端131通入水流，使水流撞击所述柔性部件2，进而使所述柔性部件2发生形变，导致所述吸液腔12内部的体积发生变化，使衣物处理剂投放至洗衣机内或使衣物处理剂吸入吸液腔12中。
当所述进水端131停止进水时，所述弹性元件32恢复形变推动所述保护套筒31向容纳腔11运动，所述柔性部件2的形变部22恢复形变并移动至初始位置并重新覆盖泄压端132，吸液腔12内部体积增大，将衣物处理剂由吸入吸液腔12。
进一步地，所述保护装置3包括保护套筒31和弹性元件32。
所述保护套筒31的一端与所述柔性部件2连接。
所述弹性元件32的一端与所述保护套筒31连接，所述弹性元件32的另一端与所述吸液腔12的内侧壁连接。
本发明通过将所述保护套筒31的一端与所述柔性部件2连接，并将所述弹性元件32的一端与所述保护套筒31连接，所述弹性元件32的另一端与所述吸液腔12的内侧壁连接，进一步保证了在挤压柔性部件2的力降低时，对柔性部件2提供恢复至自然状态的恢复力。
进一步地，所述保护套筒31的一端为封闭端，所述封闭端的中部向所述柔性部件2的方向设置凸起环313形成凹腔311；
所述突出结构211的另一端向所述保护套筒31的方向凸出设置形成第一凸体2111，所述第一凸体2111插入所述凹腔311内。
具体地，所述封闭端的中部向所述柔性部件2的方向设置凸起环313形成凹腔311，所述凹腔311底部继续向所述保护套筒31的内部凹陷。所述突出结构211的另一端向所述保护套筒31的方向凸出设置形成第一凸体2111，所述第一凸体2111的中心为空腔。所述第一凸体2111的环形侧壁与所述突出结构211的内侧壁存在一定的间隙。所述间隙大于等于所述凹腔311侧壁的截面长度。
所述第一凸体2111插入所述凹腔311内，所述凸起环313插入所述第一凸体2111的环形侧壁与所述突出结构211的内侧壁存在的间隙中。
更具体地，所述第一凸体2111自所述覆盖部21的中部的第一位置向所述保护套筒31的方向延伸设置，然后弯折向所述泄压端132的方向延伸设置，然后再次弯折向所述容纳腔11的方向延伸设置，并且所述第一凸体2111的延伸终端与所述覆盖部21的中部的第二位置连接。所述第一位置、所述第二位置与所述覆盖部21的边缘存在一定的距离。
进一步地，所述保护套筒31的另一端为开口端，所述弹性元件32的一端伸入所述保护套筒31内部与所述保护套筒31连接。
具体地，所述保护套筒31封闭端的内侧壁上设置有固定筋312，所述弹性元件32的一端通过所述固定筋312固定在所述护套筒的内部。
所述壳体1还包括第三壳体15，所述第三壳体15设置在所述吸液腔12的内部。所述第三壳体15设置在所述保护套筒31的下方，其内径大于所述保护套筒31的外径。
具体地，所述第三壳体15的一端为开口端，所述弹性元件32的另一端伸入所述保护套筒31第三壳体15，并固定在所述第三壳体15的底壁上。
所述第三壳体15的开口端与所述保护套筒31的开口端相对设置。在进水端131进水时，水流挤压所述柔性部件2使所述形变部22产生形变，所述柔性部件2向吸液腔12运动并带动所述保护套筒31挤压所述弹性元件32，使所述弹性元件32压缩；同时，由于所述保护套筒31的外径小于所述第三壳体15的内径，即所述保护套筒31在所述第三壳体15的内外进行移动。另外，由于所述保护套筒31的另一端为封闭端，在所述保护套筒31向所述第三壳体15内部移动时，保证了所述吸液腔12内部对衣物处理剂的压力，使衣物处理剂最大限量的排出吸液腔12。
所述第三壳体15的另一端为封闭端，所述出液端152和进液端151设置在第三壳体15的封闭端上。
所述出液端152和进液端151上设有单向阀，所述单向阀用于使所述衣物处理剂只能从进液端151进入吸液腔12内，使所述衣物处理剂只能从出液端152排出吸液腔12。
一种具体地实施方式是，本发明的出液端152为出液管，出液管上安装出液单向导通装置，出液单向导通装置包括阀体、阀盖、阀芯及复位弹簧，阀体内部具有中空通道，阀体的中空通道一端与出液管连通，阀体内中空通道上远离出液管的一端安装阀盖，阀盖上开设阀孔，阀芯的一端可相对运动的安装在阀盖阀盖，另一端与阀体内与出液管连接的中空通道一端相配合，复位弹簧的一端止抵在阀盖上，另一端止抵在阀芯上。
洗衣机控制由进水端131进水，进水挤压柔性部件2向洗液腔运动，所述形变部22产生变形，洗液腔容积减小，洗液腔内部压力增大，将阀芯顶动，阀芯不再封堵阀体内部的中空通道，出液单向导通装置导通，衣物处理剂由出液管排出进行投放。
本发明的进液端151为进液管，进液管上安装进液单向导通装置，进液单向导通装置包括阀体、阀盖、阀芯及复位弹簧，阀体内部具有中空通道，阀体的中空通道一端与储放盒连通，另一端与进液管连通，阀体内与进液管相连接的中空通道一端安装阀盖，阀盖上开设阀孔，阀芯的一端可相对运动的安装在阀盖阀盖，另一端与阀体内与进液管连接的中空通道一端相配合，复位弹簧的一端止抵在阀盖上，另一端止抵在阀芯上。
洗衣机控制由进水端131进水，进水挤压柔性部件2向洗液腔运动，所述形变部22产生变形，洗液腔容积减小，洗液腔内部压力增大，顶住阀芯与阀体内部的中空通道保持密封接触，进液单向导通装置保持关闭。洗衣机控制停止由进水端131进水，形变部22恢复形变，洗液腔体积增大，压力减小，外部压力将阀芯推动，阀芯不再封堵阀体内部的中空通道，进液单向导通装置导通，衣物处理剂由进入到储液腔内。
进一步地，为了增加出液单向导通装置、进液单向导通装置的密封性，阀 芯的密封端上安装密封圈。
需要说明的是，本发明的自动投放装置的初始状态，进液端151、出液端152上的单向导通装置保持关闭，初始使用时，洗液腔内充满空气，因此，洗衣机控制由进水端131第一次进入时，将洗液腔内的空气排出。洗衣机控制停止由进水端131进水，柔性部件2恢复到自然状态，衣物处理剂被吸入到储液腔内。洗衣机控制由进水端131再次进入时，柔性部件2向洗液腔内运动，将衣物处理剂通过出液端152排出，实现自动投放。
如图5至6所示，所述自动投放装置还包括投放盒4，所述投放盒4设置包括第一腔室和第二腔室，所述第一腔室与分别与所述泄压端132和投放管142连通；所述第二腔室与所述抽吸管141连接。
具体地，所述第一腔室为混合输送水路41，所述混合输送水路41分别与所述泄压端132和投放管142连通，混合输送水路41用于将洗涤液与泄压水混合后投放至衣物处理设备。
所述第二腔室为洗涤剂储存装置42，所述洗涤剂储存装置42设置在所述混合输送水路41的下方，洗涤剂储存装置42与所述抽吸管141连接。
在进水端131进水时，挤压柔性部件2向吸液腔12运动，将衣物处理剂排放至洗涤剂输送水路，同时打开泄压端132，使容纳腔11与泄压输送水路412导通，水流通过泄压输送水路412将衣物处理剂冲入衣物处理装置内。
本发明通过将泄压端132与混合输送水路41导通设置，在洗涤剂投放之后，使泄压水对混合输送水路41进行冲洗，避免了输送管路中存在残留的洗涤剂而导致输送管路堵塞的情况发生，增加了所述投放盒4的使用寿命，也避免了由于洗涤液与水流混合的不充分而导致衣物受到损坏。
具体地，所述混合输送水路41的一端分别与所述泄压端132和投放管142连通，所述混合输送水路41的另一端设置有洗投放口43，所述洗投放口43用于将衣物处理剂与泄压水的混合物投放至洗衣机的衣物处理装置中。
另外，所述混合输送水路41包括洗涤剂输送水路411和泄压输送水路412。所述洗涤剂输送水路411通过投放管142与所述吸液腔12连通。
所述泄压输送水路412的一端分别与所述洗涤剂输送水路411、容纳腔11连通，所述泄压输送水路412的另一端与所述投放口43连通。所述泄压输送水路412通过所述泄压端132与容纳腔11连通。
所述自动投放装置通过进水端131向容纳腔11进水，挤压柔性部件2向吸液腔12运动，将衣物处理剂排放至洗涤剂输送水路411，同时容纳腔11与泄压输送水路412导通，水流通过泄压输送水路412将衣物处理剂冲入衣物处理装置内。
所述投放盒4的一端设有泄压口，所述泄压口与所述泄压输送水路412的侧壁存在一定的距离。所述混合输送水路41的内径大于所述泄压端132的内径。
所述泄压端132通过所述泄压口插入投放盒4内。具体地，所述泄压端132的端口插入至所述洗涤剂输送水路411与泄压输送水路412的连接处。优选的，所述泄压端132的端口超过所述涤剂导通水路411与泄压输送水路412的连接处。
本发明通过将洗涤剂输送水路411与泄压输送水路412导通设置，在衣物处理及投放之后，使泄压水对泄压输送水路412和洗涤剂输送水路411进行冲洗，避免了输送管路中存在残留的洗涤剂而导致输送管路堵塞的情况发生，增加了所述投放盒4的使用寿命，也避免了由于洗涤液与水流混合的不充分而导致衣物受到损坏。
再者，所述洗涤剂储存装置42通过所述抽吸管141与所述自动投放装置连通。
一种实施方式是，所述洗涤剂储存装置42与所述投放盒4一体成型，所述洗涤剂储存装置42固定设置在所述投放盒4的内部。
另一种实施方式是，所述洗涤剂储存装置42可抽拉的设置在所述投放盒4的内部。
本发明采用的方案为：所述洗涤剂储存装置42可抽拉的设置在所述投放盒4的内部。具体地，所述投放盒4的一侧设置有灌注口44，衣物处理剂通过所述灌注口44注入洗涤剂储存装置42中。
需要说明的是，本发明的自动投放装置可针对不同的衣物处理剂设置多个洗涤剂储存装置42，每一洗涤剂储存装置42的储液腔存放不同种类的衣物处理剂，控制进水在对应的时间进入相应的洗涤剂储存装置42内，满足各种衣物处理剂的投放要求。因此，本发明的自动投放装置能够保证多种不同的洗涤剂及护理剂添加过程中无残，不会产生不同洗涤剂护理剂相互污染的问题，有效提高衣物的洗涤效果。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，上述实施例中的实施方案也可以进一步组合或者替换，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
