一种用于自充气制品的充排流机构以及自撑袋、充排骨架或者自充排泡腔支撑骨架
本申请要求于2019年05月31日提交中国专利局、申请号为CN201910473480.6，申请名称为“一种用于自充气制品的充排流机构以及自撑袋、充排骨架”、2019年05月31日提交中国专利局，申请号为CN201910473454.3，申请名称为“一种自充排泡腔支撑骨架”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及自充气制品技术领域，具体涉及一种用于自充气制品的充排流机构及充排骨架、自撑袋或者自充排泡腔支撑骨架。
背景技术
目前充气气垫、空气床垫或者充气袋等自充气制品，其充气模式为气筒、脚踏气泵与电动气泵打气为主，多数自充气制品环形拉筋与直条隔断拉筋，充气链接口多以气筒与电动气泵出气口为标准配备充气口配件，充气时间长，成本高；而人工打气，气垫制品的材料多以聚氯乙烯为主，其中添加增塑剂和抗老化剂等成分，增塑剂和抗老化剂等都是带有毒性，费时费力；
现有的充气制品还有以聚氨酯为材料制成，这种材料密度大，使得充气制品本身重量相对于其他材料制成的重量增加，充气口易老化而影响密封性，如果配备气泵或者电动气泵，重量将明显超过同类产品的重 量，同时携带气泵等配件成了额外负担，尤其在户外使用时，降低了充气制品的便携性，给使用者带来了不好的使用体验。
另一方面，充气制品中的充气骨架，其充气模式为气筒、脚踏气泵与电动气泵打气为主，多数充气骨架多为环形拉筋与直条隔断拉筋，充气连接口多以气筒或者电动气泵出气口为标准配备充气口配件，虽然提高了充气效率，但也在一定程度上降低了充气骨架这类充气制品的便携性，影响了使用体验；虽然也可以通过人工给充气骨架充气，但是由于充气骨架的体积较大，单纯靠嘴吹气非常费力，这些问题都是由于充气口结构设计不合理导致的充排气速度慢，而且充气骨架结构简单，整体强度较弱、支撑效果差。
因此，本领域需要一种用于自充气制品的充排流机构及充排骨架、自撑袋或者自充排泡腔支撑骨架来解决上述问题。
申请内容

在一些可选实施例中，如图12所示，泡撑骨架为内泡撑骨架8，内泡撑骨架8设置在充气腔6的内部，内泡撑骨架8的第一充气口密封设置在内泡撑骨架8和充气腔6的贴靠连接处，使得第一充排机构9只能对内泡撑骨架8进行充气和排气，不影响充气腔6内的气体压力，第一 充气口和第二充气口设置在不同的位置。
在一些可选实施例中，如图11所示，泡撑骨架为外泡撑骨架7，外泡撑骨架7设置在充气腔6的外部，第一充气口和第二充气口设置在不同的位置。
在一些可选实施例中，第一充排机构9包括至少一个充排机构，如图1至5所示，第二充排机构包括至少两个充排机构；充排机构包括自封溢流管1和排流匙2，自封溢流管1包括充流端11和密封端12，充流端11和密封端12连通设置，排流匙2包括第一端21和第二端22，排流匙2只在排气时使用；自封溢流管1的外壁与充气制品的充气口密封设置；外部气源通过自封溢流管1进行充气，当到达所需充气体积或者压力时，停止充气后，自封溢流管1的密封端12在充气制品内部压力的作用下，实现自动封口；在排气时，排流匙2使自封溢流管1的密封端12撑开缝隙，破坏自封溢流管1的自密封状态，由于充气制品内部压力高于外部压力，充气制品内的气体从缝隙向外排气。在本申请中，自封溢流管1为薄膜结构，但不限于塑料薄膜，也可以是金属薄膜(如厚度为0.01毫米的不锈钢薄膜)或者其他材质的薄膜，便于形成自密封，且密封效果好。更在一些可选实施例中，第一充排机构9为两个充排机构；第二充排机构为四个充排机构，且并排设置。
在一些可选实施例中，在排气时，排流匙2的第二端22从自封溢流管1的充流端11伸入，并将自封溢流管1的密封端12撑开缝隙，由于充气制品内腔的气压高于外部气压，充气制品内腔的气体通过缝隙进行快速排气。
此外，排流匙2的第二端22至少设置有一个叉齿23。排流匙2的第二端22可以设置一个叉齿23，两个叉齿23或者三个；叉齿23可是直线型，也可以是具有一定的弧度；排流匙2的形状可以使圆柱状，也可以是板状，本领域技术人员对排流匙2的形状的改变均应限制在本申请的保护范围之内。更在一些可选实施例中，排流匙2为板状结构，在排流匙2的第二端22设置三个叉齿23，相邻的叉齿23之间具有一定的间隔。 更在一些可选实施例中，排流匙2的长度大于自封溢流管1的长度，排流匙2操作方便，轻轻一捅，将处于闭合状态的自封溢流阀的密封端12捅开一条缝隙，即可进行排气。
在本申请中，为了解释充气过程，假设一个大型(圆筒或者方型)密封充气腔6腔和泡撑骨架(可以为内泡撑骨架2，也可以是外泡撑骨架3)，当用附带的挤压腔的自封溢流管1向泡撑骨架充气时，泡撑骨架逐渐撑开，而密封充气腔6的腔体也因为泡撑骨架的撑开而增大体积，造成密封充气腔6内部气压低于外部气压，外部气体通过密封充气腔6所配置的自封溢流管1向密封充气腔6的腔内充气，因为密封充气腔6的体积比泡撑骨架大得多，所以密封充气腔6所配置的密封充气腔6的单位时间内充气量比泡撑骨架也大得多，所以密封充气腔6所配置的自封溢流管1的数量要至少是自封溢流管1的4倍以上才能满足充气效率的要求，密封充气腔6所配置的自封溢流管1采用并排设置的方式方便同时排气。为了提高密封充气腔6的腔体的充气速率，可以把密封充气腔6所配置的自封溢流管1中的排流匙2预先推入第二卡环14，当泡撑骨架完成充气后，附带挤压腔的自封溢流管1自动密封，密封充气腔6也因为泡撑骨架的定型而停止涨大，当密封充气腔6内的气压与外部气压一致时，可以把密封充气腔6所配置的自封溢流管1中的排流匙2拉回第一卡环13，此时密封充气腔6所配置的自封溢流管1自动密封。至此完成密封充气腔6的充气动作。
在一些可选实施例中，如图6至8所示，自封溢流管1的内侧壁设置有第一卡环13和第二卡环14，第一卡环13和第二卡环14设置在远离自封溢流管1密封端12一侧，第一卡环13位于充流端11一侧，排流匙2上的第二端22上设有凸起24；在非排气状态时，第一卡环13和凸起24卡置连接，此时，充气制品的内部压力高于外部压力，自封溢流管1的密封端12在充气制品内部压力的作用下处于密封状态；在排气状态时，第二卡环14和凸起24卡置连接，此时，排流匙2的第二端22将自封溢流管1的密封端12撑开缝隙，破坏自封溢流管1的自密封状态，由于充 气制品的内部压力高于外部压力，充气制品内的气体从缝隙快速排出。本领域技术人员对第一卡环13、第二卡环14和凸起24的形状的改变均应限制在本申请的保护范围之内。在一些可选实施例中，自充排泡腔支撑骨架还包括保护层，保护层用于包裹泡撑骨架或者充气腔6。保护层可以是塑料布、帆布、金属膜布或者硬塑板中的一种或多种。
在一些可选实施例中，自充排泡腔支撑骨架还包括挤压腔，挤压腔设置在第一充气口和第二充气口处，用于辅助充气。挤压腔是由环状挤压壁围成的开口腔体。
在一些可选实施例中，挤压腔与自充排泡腔支撑骨架为一体结构。
在一些可选实施例中，挤压腔与自充排泡腔支撑骨架为可分离结构，充气完毕即可将挤压腔从骨架的第一充气口和充气腔6的第二充气口处移除。
充入物质是气体时，通过两只手打开辅助挤压腔，使挤压腔中装入空气，然后用一只手束紧挤压腔的入口，形成挤压腔密封状态，另一只手稍微用力按压挤压腔，使挤压腔中的空气通过自封溢流管1进入泡撑骨架中，从而逐渐撑开外壳，充满时外壳已经展开到位。如有送气设备，直接将挤压腔套在送气管上束紧即可进行充气。
充入物质是液体或粉末时，预先将物质倒入挤压腔，一般装入到挤压腔2/3体积时，用手束紧挤压腔入口，形成挤压腔密封状态，另一只手稍微用力按压挤压腔，使挤压腔中的物质通过自封溢流管1进入泡撑骨架中。如有水龙头或送粉机的，直接用手把挤压腔对接束紧在水龙头或送粉管上即可完成装填。
泡撑骨架充满时，泡撑骨架内压力高于外部气压，当挤压腔停止挤压动作时，自封溢流管1的密封端12会因泡撑骨架内压力大于外部气压而自动紧闭封锁，从而形成稳定的泡腔骨架支撑结构。拆除时，轻轻把排流匙2推进自封溢流管1的密封端12撑开缝隙，即可实现快速排流，排完后折叠收纳。
充排流机构包括自封溢流管1、排流匙2；自封溢流管1包括充流端 11和密封端12，充流端11和密封端12连通设置，排流匙2包括第一端21和第二端22，排流匙2只在排气时使用；自封溢流管1的外壁与充气制品的充气口密封设置；外部气源通过自封溢流管1进行充气，当到达所需充气体积或者压力时，停止充气后，自封溢流管1的密封端12在充气制品内部压力的作用下，实现自动封口；在排气时，排流匙2使自封溢流管1的密封端12撑开缝隙，破坏自封溢流管1的自密封状态，由于充气制品内部压力高于外部压力，充气制品内的气体从缝隙向外排气。本申请中的充排流机构可以适用于气体、液体和固体粉末的充入和排放。
与上述不同的，在自封溢流管1的内侧壁设置有第一卡环13和第二卡环14，第一卡环13和第二卡环14设置在远离自封溢流管1密封端12一侧，第一卡环13位于充流端11一侧，排流匙2上的第二端22上设有凸起24；在非排气状态时，第一卡环13和凸起24卡置连接，此时，充气制品的内部压力高于外部压力，自封溢流管1的密封端12在充气制品内部压力的作用下处于密封状态；在排气状态时，第二卡环14和凸起24卡置连接，此时，排流匙2的第二端22将自封溢流管1的密封端12撑开缝隙，破坏自封溢流管1的自密封状态，由于充气制品的内部压力高于外部压力，充气制品内的气体从缝隙快速排出。
本申请可在如下场合使用：
具有充排流机构的自撑袋，可以是背心袋或普通购物袋等，因为普通塑料袋无法保型支撑，由于该自撑袋的保型性，可以充分利用空间，且可以随意放置于地面上不会倾倒，可节省巨大数量的普通塑料背心袋，从而有效减少白色污染。
具有充排流机构的自撑桌、椅、床等，简便设置，方便收纳。自撑椅子充气后就能用，而且充气迅速，密封性好，拆除的时候推动排流匙排出空气收起，节省空间和时间，可重复多次利用，尤其适合户外使用。
具有充排流机构的自撑袋可用于简易杂物袋、箱，简便设置，不需要箱体作支撑，方便收纳。

虽然，上文中已经用一般性说明及具体实施例对本申请作了详尽的描述，但在本申请基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本申请精神的基础上所做的这些修改或改进，均属于本申请要求保护的范围。
