Description

一种便于垃圾袋使用的垃圾桶 技术领域
本发明涉及垃圾桶领域。
 背景技术
市面上垃圾桶多数以金属或塑胶制，用时放入塑料袋，当垃圾一多便可扎起袋丢掉。但是这个垃圾桶存在以下问题：垃圾袋套到垃圾桶上时总是不能服帖在桶壁上，造成垃圾袋容量减少，而且垃圾袋口不能很好的固定在垃圾桶口，使垃圾袋容易跟随垃圾收缩进垃圾桶内，另外拿出垃圾袋时，袋内总是有大股的空气，不易打包扔掉，存在一定的使用方便。
因此，如何对现有的垃圾桶进行改进，使其克服上述问题是本领域技术人员亟待解决的一个问题。
 技术解决方案
本发明的目的在于提供一种便于垃圾袋使用的垃圾桶，其在套上垃圾袋后，能够使垃圾袋服帖在桶壁上，而且能很好的固定袋口，另外当拿出垃圾袋时，能挤出垃圾袋中的空气，并起到一定的压缩的作用，方便打包垃圾。
为达到以上目的，本发明采用的技术方案为：一种便于垃圾袋使用的垃圾桶，其特征在于：包括外桶体、内桶体和开合装置；
所述外桶体底部为通气结构，所述外桶体侧壁为密闭结构；
所述内桶体整体为通气结构，所述内桶体可活动的设置于所述外桶体内；
所述开合装置包括活塞隔板、驱动部件、下连杆、上连杆、升降环、开启件和袋口扣件；所述活塞隔板滑动设置于所述外桶体内壁，且紧密配合，所述内桶体位于所述活塞隔板上方，所述驱动部件设置于所述外桶体和所述活塞隔板之间，用于驱动所述活塞隔板升降， 所述下连杆固定于所述活塞隔板上，所述上连杆固定于所述升降环上，所述下连杆和所述上连杆之间限位滑动连接，所述下连杆向上移动至所述上连杆的上限位处时，继续向上移动能带动所述上连杆同步移动，所述下连杆向下移动至所述上连杆的下限位处时，继续向下移动能带动所述上连杆同步移动，所述开启件下端铰接于所述升降环上，所述开启件上端铰接于所述袋口扣件内侧上，所述袋口扣件外侧还铰接于所述外桶体上，所述升降环的升降能通过所述开启件的联动，实现所述袋口扣件相对所述外桶体发生翻转；
所述袋口扣件为至少两个，所述袋口扣件向内翻转到位时，能构成封闭的环形结
构，且能紧贴所述内桶体上沿和所述外桶体外壁；当垃圾袋位于所述内桶体内时，所述垃圾袋的袋口能夹紧于所述袋口扣件和所述内桶体上沿之间，此时所述垃圾袋、所述外桶体的侧壁、所述活塞隔板和所述袋口扣件构成密封的变压腔，所述活塞隔板的升降能改变所述变压腔的容积，进而改变所述变压腔的气压，使其和大气压产生压力差，该压力差能使所述垃圾袋紧贴所述内桶体内壁或使所述垃圾袋进行压缩。
作为优选，所述驱动部件包括踏板、推杆、长抬升杆和短抬升杆，所述踏板铰接于

作为改进，该垃圾桶还包括泄压装置，所述泄压装置设置于所述外桶体上，连通所述变压腔，用于防止所述变压腔内气压过大。
作为优选，所述袋口扣件为三个，且能构成密封的圆环状结构。
 有益效果
与现有技术相比，本发明的优点在于：1、套装垃圾袋时，先通过袋口扣件夹紧垃圾袋，再通过活塞隔板下降，使变压腔体积增大，气压变小(小于大气压) ，在大气压的作用下使垃圾袋紧贴内桶体。2、取出垃圾袋时，活塞隔板先上升，使变压腔体积减小，气压增大(长时间的放置的情况下，变压器腔内的气压会趋于大气压) ，并大于大气压，对垃圾袋内的垃圾进行一定的压缩，再袋口扣件开启，方便打包垃圾袋。

 本发明的最佳实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。
如图1～11所示，本发明的一个实施例包括外桶体1、内桶体2、开合装置3和泄压装置4。具体关系及结构如下：
外桶体1底部为通气结构，外桶体1侧壁为密闭结构。
内桶体2整体为通气结构，内桶体2可活动的设置于外桶体1内。
开合装置3包括活塞隔板31、驱动部件32、下连杆33、上连杆34、升降环35、开启件36和袋口扣件37；活塞隔板31滑动设置于外桶体1内壁，且紧密配合，内桶体2位于活塞隔板
31上方，驱动部件32设置于外桶体1和活塞隔板31之间，用于驱动活塞隔板31升降，下连杆
33固定于活塞隔板31上，上连杆34固定于升降环35上，下连杆33和上连杆34之间限位滑动连接，下连杆33向上移动至上连杆34的上限位处时，继续向上移动能带动上连杆34同步移动，下连杆33向下移动至上连杆34的下限位处时，继续向下移动能带动上连杆34同步移动， 开启件36下端铰接于升降环35上，开启件36上端铰接于袋口扣件37内侧上，袋口扣件37外侧还铰接于外桶体1上，升降环35的升降能通过开启件36的联动，实现袋口扣件37相对外桶体1发生翻转。
袋口扣件37为三个，袋口扣件37向内翻转到位时，能构成封闭的圆形环形结构，且能紧贴内桶体2上沿和外桶体1外壁；当垃圾袋100位于内桶体内时，垃圾袋的袋口能夹紧于袋口扣件37和内桶体2上沿之间，此时垃圾袋100、外桶体1的侧壁、活塞隔板31和袋口扣件37构成密封的变压腔A，活塞隔板31的升降能改变变压腔A的容积，进而改变变压腔A的气压，使其和大气压产生压力差，该压力差能使垃圾袋100紧贴内桶体2内壁或使垃圾袋进行压缩。
泄压装置4设置于外桶体1上，连通变压腔A，用于防止变压腔A内气压过大。
选择一种实现方式，驱动部件32包括踏板321、推杆322、长抬升杆323和短抬升杆324，踏板321铰接于外桶体1外侧，推杆322沿水平方向滑动设置于外桶体1上，长抬升杆323一端铰接于推杆322上，长抬升杆323另一端铰接于活塞隔板31上，短抬升杆324一端铰接于长抬升杆323中段，短抬升杆324另一端铰接于外桶体1底部；踏板321的上下翻转，能带动推杆322的左右滑动，进而通过长抬升杆323和短抬升杆324的联动，实现活塞隔板31的升降。
本实施例的工作过程分别以下流程：
1、步骤状态一(如图6所示) ，此时袋口扣件37翻转至最内侧，活塞隔板31处于最下方，下连杆33处于上连杆34的下限位处。
 2、步骤状态二(如图7所示) ，此时踩下踏板321，使活塞隔板31上升，进而带动下连杆33移动至上连杆34的上限位处，再带动上连杆34、升降环35、开启件36活动，使袋口扣件37向外翻转，再将垃圾袋100套在内桶体2上。
[0036]   3、步骤状态三(如图8所示) ，此时松开踏板321，在重力作用下，活塞隔板31、下连杆33、上连杆34、升降环35、开启件36同时下降，袋口扣件37向内翻转，夹紧垃圾袋100。[0037] 4、步骤状态四(如图9所示) ，此时上连杆34、升降环35、开启件36不再活动，下连杆33和活塞隔板31继续下降，下连杆33从上连杆34的上限位处滑动到下限位处，使变压腔A的体积增大，气压变小(小于大气压) ，在大气压的作用下使垃圾袋100紧贴内内桶体2。步骤1 至4完成了垃圾袋100的套装过程。
5、步骤状态五(如图10所示) ，为了取出垃圾袋100，踩下踏板321，使活塞隔板31上升，同时带动下连杆33移动至上连杆34的上限位处，使变压腔A体积减小，气压增大(长时间的放置的情况下，变压器腔A内的气压会趋于大气压) ，并大于大气压，对垃圾袋100内的垃圾进行一定的压缩。
6、步骤状态六(如图11所示) ，此时活塞隔板31继续上升，再带动上连杆34、升降环35、开启件36活动，使袋口扣件37向外翻转，再取出装有垃圾的垃圾袋100即可。
[0040] 以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是本发明的原理，在不脱离本发明精神和范围的前提下本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明的范围内。本发明要求的保护范围由所附的权利要求书及其等同物界定。
