3、本发明的铝封管使阀体与内管之间连接更加紧密，防止内管内的水泄漏。
4、本发明的壳体与阀体之间设置有第一密封圈，所述第一密封圈用于密封第一腔室，防止第一腔室内的水泄漏；壳体与所述波纹管之间设置有密封套，所述密封套用于密封第一腔室，防止第一腔室内的水泄漏。
5、本发明由于膨胀棉吸水后膨胀，框架向右移动，框架的颜色为红色，从阀体外看到视镜显示红色，正常视镜是透明的，表明防泄漏水管组件进入自锁状态，此时需更换新水管，实用简单，操作便捷，可以及时提醒使用者更换水管。
6、本发明的分流滤网用于引导水流从阀芯组件的侧边流过，避免水流直接冲击下方的阀芯组件，引发进水组件的自锁；通过设置的支撑筋可以防止分流滤网发生变形，避免分流滤 网因其塑料材质未完全冷却时较软而导致分流滤网刚出模具顶出时滤网挤压在一起而产生变形。
7、本发明的第二螺母内设置有台阶，所述内扣与所述台阶相配合；内扣套入第二螺母后，第二螺母设置的台阶使内扣撑开无法从第二螺母内脱出，在安装完橡胶垫后，内扣被固定在台阶上，不会向下滑动，也杜绝内扣掉落脱出的风险，所述内扣和第二螺母的材质均为塑料，由于塑料件出模后会出现向内收缩的情况，将所述内扣设置呈C型，设计时会加大内扣的直径，使内扣收缩后会正好符合要求的尺寸；在阀体1装上内扣，手动扣上第二螺母即可

实施例1
一种防泄漏进水管组件，如图1-8所示，包括阀体1，所述阀体1外套设有壳体2，所述壳体2内设置有波纹管4，所述阀体1的一端套设有第二螺母20，另一端连接有内管5，所述内管5背离阀体1的一端连接有弯管10，所述弯管10的端头套设有第一螺母11，所述内管5位于所述波纹管4内且与波纹管4之间设有第二腔室24，所述内管5为PVC管，所述阀体1内设有中心承压通道22，所述中心承压通道22与所述内管5的内部连通，所述内管5的内部与所述弯管10的内部连通，所述壳体2内设置有第一腔室23，所述第一腔室23与所述第二腔室24连通。所述第二螺母20和水龙头组件进行装配，所述弯管10、第一螺母11装配在洗衣机上，如图3或4所示，所述防泄漏进水管组件正常工作时，水流从左向右流动。
进一步地，所述中心承压通道22内设置有阀芯组件18，所述阀芯组件18能够在中心承压通道22内移动，阀芯组件18的一端固定连接有框架17，所述框架17内设置有膨胀棉15，所述膨胀棉15与所述第一腔室23连通，膨胀棉15的一端设置有框架17，另一端设置有底座16。当所述第一腔室23内通水时，与第一腔室23连通的膨胀棉15吸水膨胀，膨胀的膨胀棉15的一端与底座16相抵触，另一端与框架17相抵触，使底座16与框架17发生相对位移，使框架17向右移动，继而使与框架17固定连接的阀芯组件18向右移动。
进一步地，所述阀芯组件18外套设有第二密封圈21，所述阀体1内设置有斜面25，当所述阀芯组件18向右移动时，所述第二密封圈21与阀体1内的斜面25接触密封，以截断中心承压通道22与水龙头组件之间的连通，从而切断水流，防止水泄漏。
进一步地，所述阀体1靠近所述第二螺母20一端的内部连接有分流滤网29，所述分流滤网29包括滤网292以及设置在所述滤网292上的分流板291，所述分流滤网29的外侧设置有若干个支撑筋293，分流滤网29的底部设置有底板294，所述底板294与所述阀体1的 内壁之间具有间隙，水流经过所述分流板291分流后从所述分流滤网29透过，并从所述底板294与所述阀体1的内壁之间的间隙流入到所述中心承压通道22内。分流滤网29用于引导水流从阀芯组件18的侧边流过，避免水流直接冲击下方的阀芯组件18，引发进水组件的自锁；通过设置的支撑筋293可以防止分流滤网29发生变形，避免分流滤网29因其塑料材质未完全冷却时较软而导致分流滤网29刚出模具顶出时滤网292挤压在一起而产生变形。
进一步地，所述阀体1与所述内管5之间还设置有铝封管7，所述铝封管7使阀体1与内管5之间连接更加紧密，防止内管5内的水泄漏。
进一步地，所述弯管10通过卡箍8和卡扣9与所述波纹管4连接，弯管10与内管5之间也设置有铝封管7；弯管10与波纹管4之间设置有弯头密封套26，所述弯头密封套26靠近所述壳体2的一侧设置有弯头密封圈斜面32，所述弯管10靠近所述内管5的一侧设置有斜坡31。其中，弯管10套上弯头密封套26后塞进所述波纹管4内，弯头密封套26起到弯管10和波纹管4之间的密封作用，设置的弯头密封圈斜面32使得弯头密封套26容易插入波纹管4内，可使得弯头密封套26实现紧密的密封作用，防止漏水；弯管10设置的具有斜面和圆角的斜坡31可以增加弯管10尾部的壁厚，增加强度，提高抗折断需要的力，避免出现断裂的情况。
进一步地，所述第一螺母11内设置有弯头垫片12，所述弯管10的端部设置有槽口27，所述弯头垫片12嵌设在所述槽口27内。在弯管10的端部先套上弯头垫片12后再装入第一螺母11，弯头垫片12被所述槽口27卡住，以防止掉落。
进一步地，所述阀体1上开设有凹槽33，所述壳体2与所述阀体1的凹槽33之间嵌设有第一密封圈3，所述第一密封圈3用于密封第一腔室23，防止第一腔室23内的水泄漏。阀体1与壳体2安装到位后第一密封圈3即可起到密封的作用，通过设置的凹槽33可以有效防止第一密封圈3在内部高水压下冲出，提高第一密封圈3冲出壳体2外的所需的压力，能够有效防止第一密封圈3脱出。
进一步地，所述第二螺母20卡接在所述阀体1上，第二螺母20内设有橡胶垫19，所述橡胶垫19与所述阀体1的侧端盘面相抵触；所述第二螺母20内还设置有内扣28，所述内扣28位于第二螺母20与阀体1之间且与阀体1相抵接；所述第二螺母20内设置有台阶30，所述内扣28与所述台阶30相配合。所述内扣28用于连接第二螺母20和阀体1，扣住内扣28后防止第二螺母20掉落。内扣28套入第二螺母20后，第二螺母20设置的台阶30使内扣28撑开无法从第二螺母20内脱出，在安装完橡胶垫19后，内扣28被固定在台阶30上，不会向下滑动，也杜绝内扣28掉落脱出的风险。可选地，所述内扣28和第二螺母20的材质均为塑料，由于塑料件出模后会出现向内收缩的情况，将所述内扣28设置呈C型，设计时会 加大内扣28的直径，使内扣28收缩后会正好符合要求的尺寸；在阀体1上装上内扣28，手动扣上第二螺母10即可。
进一步地，所述壳体2与所述波纹管4之间设置有密封套6，所述密封套6用于密封第一腔室23，防止进入第一腔室23内的水泄漏。
进一步地，所述壳体2的底端设置有视镜13，所述视镜13与所述壳体2之间设置有视镜密封圈14。
本发明工作原理：第二螺母20和水龙头组件进行装配，弯管10、第一螺母11装配在洗衣机上。拧开水龙头，水流入阀体1内时，从阀芯组件18与阀体1的内壁之间的间隙即中心承压通道22，流入到内管5的内部，再从内管5的内部和弯管10的内部进入洗衣机内。
如果内管5破裂，水将流入到内管5和波纹管4的夹层即第二腔室24，第二腔室24内的水流到第一腔室23内，与第一腔室23连通的膨胀棉15吸水膨胀，膨胀的膨胀棉15的一端与底座16相抵触，另一端与框架17相抵触，使底座16与框架17发生相对位移，使框架17向右移动，继而使与框架17固定连接的阀芯组件18向右移动，当阀芯组件18向右移动时，所述第二密封圈21与阀体1内的斜面25接触密封，以截断中心承压通道22与水龙头组件之间的连通，从而切断水流，防止水泄漏。并且由于膨胀棉15吸水后膨胀，框架17向右移动，框架17的颜色为红色，从阀体1外看到视镜13显示红色，正常视镜是透明的，表明防泄漏水管组件进入自锁状态，此时需及时更换新水管。
本发明的保护范围并不仅局限于上述实施例，凡是在本发明构思的精神和原则之内，本领域的专业人员能够做出的任何修改、等同替换和改进等均应包含在本发明的保护范围之内。
