本发明的较佳实施方式
为了对本实用新型的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本实用新型的具体实施方式。
如图1、图2所示，本实用新型一个优选实施例中的垃圾桶包括桶体1和桶盖2，优选地，桶盖2可翻转地安装在桶体1上，以打开后投放、取出垃圾。
桶盖2可以集成存放垃圾袋3、垃圾袋3展开、垃圾袋3打包、垃圾袋3切割等一整条完整的垃圾袋3处理动作，基本可以实现自动化。
结合图3、图4所示，桶盖2包括主体21和转动设置在主体21上侧的盖体22，主体21上设有旋转打包机构23、以及自动切割机构24，盖体22上设有鼓风展开机构25，以在转动到主体21上后向旋转打包机构23的环形存放盒231上敞开的垃圾袋3吹气。
垃圾袋3展开后整体呈长筒状，轴向收缩后，让垃圾袋3的周圈沿存放盒231放置，且垃圾袋3封口的底部位于存放盒231的中部。垃圾袋3可以切割 成若干袋体，实现连续的打包和垃圾袋3的放置展开，存放盒231的中部形成供垃圾投入到垃圾袋3中的投放口。
环形存放盒231供垃圾袋3存放并能让垃圾袋3向下展开，鼓风展开机构25让存放盒231上的垃圾袋3展开到桶体1内的、将装有垃圾的垃圾袋3旋转打包的旋转打包机构23、以及将打包后的垃圾袋3的封口切割的自动切割机构24。
结合图3至图5所示，垃圾袋鼓风展开机构25通常设置在存放盒231的上方，包括用于向垃圾桶的桶体1上端敞开的垃圾袋3吹气的送风件251，以让垃圾袋3向下展开到垃圾桶的桶体1内侧。
送风件251位于存放盒231的上侧，且送风件251的送风方向与存放盒231的内圈相对，在垃圾袋鼓风展开机构25向下吹气后垃圾袋3的底部展开到桶体1的内壁面上，上端存放盒231的内圈可以作为投放口让垃圾从此投入。
借用鼓风展开机构吹风的方式展开垃圾袋，展开方式智能快捷，新垃圾袋内没有放置和接触过垃圾，干净卫生，吹气过程不会有异味流动，能减少环境中的异味。
送风件251的出风口2511呈长条形，可以提升垂向垃圾袋3的辐射范围。
鼓风展开机构25还包括鼓风舱252，送风件251设置在鼓风舱252内，鼓风舱252上设有供气体进入的进气口和供送风件251送出的气体吹出的送风口2521。
鼓风舱252包括下盖和上盖，进气口形成于上盖、下盖的配合面，送风口2521形成于下盖上。
鼓风舱252可翻转地设置，使得盖体22带动整个鼓风展开机构25翻转，在打开后能扔垃圾，关闭后能吹气展开垃圾袋3。
送风口2521与出风口2511正对，且送风口2521的外形不小于出风口2511。
进一步地，鼓风舱252内设有若干送风件251，鼓风舱252上设有分别与各送风件251的出风口2511相对的若干送风口2521，让各送风件251送出的风经送风口2521吹出。
进一步地，各送风件251的出风口2511首尾依次排布，形成半封闭形状，也可形成封闭的形状，或者，各送风件251的出风口2511沿同一方向依次排布，形成一字型等。
在桶盖2盖合状态，鼓风展开机构25向存放盒231内吹气让垃圾袋3向下展开贴合到垃圾桶桶体1的内壁面，盖体22可以翻转打开，向垃圾袋3内放置垃圾。
结合图6至图9所示，在垃圾袋3放满需要打包取出时，则可启动旋转打包机构23，旋转打包机构23包括用于带动存放盒231转动的旋转驱动装置232，旋转驱动装置232和存放盒231相互作用，让存放盒231及存放盒231内的垃圾袋3相对装有垃圾的垃圾袋3转动，让存放盒231转动后使得向下展开存放了垃圾的垃圾袋3旋转后将上端扭转封口。
旋转驱动装置采用旋转存放盒的方式扭转封口，封口更加的紧致，里面的垃圾不容易泄露，封口小，利于后续的自动切割。
旋转驱动装置232包括转动设置的驱动件2321，以在转动时带动存放盒231转动。进一步地，驱动件2321为转动设置、并与存放盒231周向定位的环形驱动盘，在驱动盘转动时，带动存放盒231转动，相对下面装有垃圾的垃圾袋3产生扭转。
进一步地，驱动盘和存放盒231同心设置，驱动盘和存放盒231卡合，从而在驱动盘转动时带动存放盒231转动。
在一些实施例中，驱动盘包括环形的齿环2322，齿环2322的外圈分布有齿牙，存放盒231位于齿环2322的内圈。
驱动盘还包括在齿环2322内圈设置的定位部2323，定位部2323上设有与存放盒231卡合的卡合部2324。
本实施例中，定位部2323为环形，定位部2323沿齿环2322内圈周圈设置，存放盒231放置在定位部2323上，卡合部2324为在定位的一侧向上凸起设置的凸台，存放盒231的底部设有供凸台卡入的凹槽2311。
定位部2323上沿周圈设有若干卡合部2324，与存放盒231底部的各凹槽2311卡合配合，同步转动。在其他实施例中，驱动盘和存放盒231的卡合位 置也可位于齿环2322的内壁面和存放盒231的外壁面上，或者直接在存放盒231的周圈上设置齿牙，或其他结构，让旋转驱动装置232带动存放盒231直接转动。
通常，旋转驱动装置232还包括用于带动驱动件2321转动的旋转电机2325，以及用于旋转电机2325的输出传动的齿轮组。
在装有垃圾的垃圾袋3扭转封口后，则需要和存放盒231内的垃圾袋3切割开，以进行下一次的垃圾存放。
结合图6、图9、图10所示，自动切割机构24包括第一导向组件241、第二导向组件242、第一切割组件243、第二切割组件244、以及切割驱动装置245，切割驱动装置245带动第一切割组件243沿第一导向组件241来回移动、以及带动第二切割组件244沿第二导向组件242来回移动。
第一切割组件243、第二切割组件244在来回移动时相互靠近、远离，在靠近时对垃圾袋3上端的扭转封口夹持并切割；并在远离后，留出空间供上端新的垃圾袋3向下展开。
自动切割机构对扭转封口位置夹持，需要的加热的尺寸会很短，热量需求低，加热块，耗电量低，提升环保性。
第一导向组件241、第二导向组件242分别包括并排间隔设置的第一导轨2411、第二导轨2421，第一切割组件243由第一导轨2411向第二导轨2421延伸，第二切割组件244由第二导轨2421向第一导轨2411延伸，让第一切割组件243、第二切割组件244平行并排。
第一切割组件243包括与第一导轨2411滑动配合的第一支座2431，第二切割组件244包括与第二导轨2421滑动配合的第二支座2441，第一支座2431、第二支座2441中的至少一个上设有切割件2432，在第一切割组件243、第二切割组件244靠近后，切割件2432切割封口位置。
切割件2432可拆卸地安装在第一支座2431上，并与第二支座2441相对，第二支座2441上设有与切割件2432相对的避让槽2442。当垃圾袋3扭转封口后，封口位置刚好与切割件2432的位置相对应，在第一切割组件243、第二切割组件244靠近后，切割件2432与扭转封口位置抵靠切割开。
进一步地，切割件2432为与电源电性连接的热熔头，在夹持封口后，热熔头通电升温熔断切割封口位置。
自动切割机构24还包括用于对第一切割组件243、第二切割组件244靠近后的位置进行设定的位置开关246，在第一切割组件243、第二切割组件244靠近夹持封口后停止移动，并将切割件2432与电源导通后发热，将扭转封口位置熔断。
切割驱动装置245包括用于分别驱动第一切割组件243、第二切割组件244来回移动的第一驱动组件2451、第二驱动组件2452。
第一驱动组件2451包括分别设置在第一导轨2411两端的第一主动轮2453、第一从动轮2454、以及绕设在第一主动轮2453、第一从动轮2454之间的第一传送带2455，第一传送带2455与第一支座2431连接，第一主动轮2453转动带动第一传送带2455转动，让第一传送带2455带动第一支座2431沿第一导轨2411滑动。
进一步地，第一驱动组件2451还包括第一电机和分别与第一主动轮2453、第一电机啮合的第一齿轮组，让第一电机带动第一主动轮2453转动。
第二驱动组件2452包括分别设置在第二导轨2421两端的第二主动轮2456、第二从动轮2457、以及绕设在第二主动轮2456、第二从动轮2457之间的第二传送带2458，第二传送带2458与第二支座2441连接，第二主动轮2456转动带动第二传送带2458转动，让第二传送带2458带动第二支座2441沿第二导轨2421滑动。
进一步地，第二驱动组件2452还包括第二电机和分别与第一主动轮2453、第一电机啮合的第一齿轮组，让第二电机带动第二主动轮2456转动。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
