为解决上述技术问题所采用的技术方案：
本发明提供一种下置大容量单气泵泡沫发生装置，其包括：补液机构和泡沫发生机构，补液机构包括补液槽、补液瓶，所述补液槽设置有开口朝上的套装口，所述补液瓶的下端从所述套装口套设于补液槽内，所述补液槽与外界连通，所述补液瓶的下端设置有瓶口；泡沫发生机构包括供气泵单元、混气槽腔，设置于混气槽腔上部的气液混合结构、进气口和通气阀结构，所述混气槽腔的下部与补液槽的下部连通，在所述混气槽腔与补液槽之间设置有补液单向阀，所述补液单向阀的连通方向为从补液槽往混气槽腔的方向，所述供气泵单元与进 气口连接，所述通气阀结构将所述混气槽腔与外界连通，所述气液混合结构设置有出液通道、出气通道、混合通道，所述出液通道的进口端往下延伸至混气槽腔的底部内，所述出气通道的进口端和进气口均与混气槽腔的上部连通，所述出液通道的出口端和出气通道和出口端分别与混合通道的进口连通。
本发明的有益效果是：当需要喷出泡沫时，供气泵单元给混气槽腔进行空气加压，使混气槽腔内部压强增大，这时的通气阀结构关闭，混气槽的皂液受压强作用下从出液通道进入混合通道，同时混气槽腔内的气体也在压强的作用下从出气通道进入混合通道，气体与皂液在混合通道内混合形成泡沫后一同从混合通道喷出，实现泡沫的喷出；当混气槽腔内的皂液被喷出后，混气槽腔内皂液的液面会降低，这时补液槽内的皂液在大气压强的作用下，通过补液单向阀供入混气槽腔内，直至混气槽腔与补液槽达到气压平衡，即是混气槽腔与补液槽的液面高度一致，这时的通气阀结构保持打开状态，将所述混气槽腔与外界连通；以及在补液槽内的皂液供给混气槽腔的同时，由于补液瓶下端的瓶口从所述套装口套设于补液槽内，补液槽的液面降低，补液瓶中的皂液会补充入补液槽，直至补液槽内的液面高度没过瓶口时，停止补液，从而确保补液槽内部的皂液量，本泡沫发生装置通过单个供气泵单元即可实现泡沫的产生，并且在大气压的作用下，补液瓶、补液槽与混气槽腔之间通过机械式的结构即可实现自动的供液、补液，实现大容量的使用，无需频繁进行补液。
作为上述技术方案的进一步改进，所述通气阀结构包括将所述混气槽腔与外界连通的通气腔道、上下活动设置于通气腔道内的配重堵塞体，所述通气腔道设置有呈上下设置的通气出气端和通气进气端，所述配重堵塞体用于受所述混气槽腔内高压气体的作用力而往上移动至封堵所述通气出气端。
本方案中的通气阀结构通过配重堵塞体来实现机械式的闭合，在补液槽对混气槽腔进行供液时，混气槽腔内的气压比较低的，这时的配重堵塞体会被气压往上顶，但是没有顶到封堵通气出气端，使得通气腔道处于贯通的状态，这时的混气槽腔就于外界连通，补液槽可对混气槽腔进行供液；而当供气泵单元给混气槽腔进行空气加压，混气槽腔内气压很高，高压气体会往上顶动配重堵塞体，使得配重堵塞体封堵所述通气出气端，这时的通气腔道处于关闭的状态，泡沫发生装置处于喷泡沫的状态。其中配重堵塞体的重量，本领域技术人员可根据实际的工作气压而定，本发明不进行详细的阐述。
作为上述技术方案的进一步改进，在所述通气进气端设置有用于承托配重堵塞体的环形承载台阶，所述配重堵塞体呈球状。环形承载台阶主要起到承托配重堵塞体的作用，避免配重堵塞体往下掉落，以及确保配重堵塞体可被气体往上顶动，其中通气出气端呈上小下大喇叭状结构。球状的配重堵塞体与通气腔道内壁之间形成有通气间隙。
作为上述技术方案的进一步改进，所述气液混合结构包括设置于混气槽腔顶部内的套接凹槽、套设于套接凹槽内的呈中空的套接件，所述混合通道设置于套接凹槽的顶部并与所述套接凹槽连通，所述出气通道设置于套接件的外壁与套接凹槽的内壁之间，所述套接件连接有出液管，所述出液通道形成于出液管和套接件内。
本方案中的气液混合结构主要实现气液的混合，其通过套接件套设于混气槽腔顶部的套接凹槽内而成的，在结构上更为简单，无需采用很复杂的模具制造而成。
在其他方案中，所述通气阀结构包括设置于所述混气槽腔上部的外壁的套筒，在所述套筒内设置有固定于混气槽腔外壁上的套接柱，所述套筒与套接柱之间形成套接间隙，在所述套接间隙的底部设置有与混气槽腔连通的通气槽口，所述套接间隙套设有倒置桶状的通气 套，所述通气套的顶部设置有微型通气孔结构，所述通气套的外周壁与套筒的内周壁密封抵触，而通气套的内壁与套接柱的外壁之间形成多个通气槽道，所述通气槽道的两端分别与微型通气孔结构、通气槽口连通。
在其他方案中，通气阀结构还可为电磁阀、微孔膜等一系列的流通控制装置。
作为上述技术方案的进一步改进，所述出气通道的数量为多个，多个出气通道呈环形间隔设置于套接件的外壁与套接凹槽的内壁之间。
多个出气通道可使得气体与皂液的混合更加均匀充分，气体从混合通道的四周进入，并与皂液进行混合。
作为上述技术方案的进一步改进，所述瓶口设置有补液阀结构，所述补液槽设置有用于与补液阀结构抵触而使所述补液阀结构打开的补液顶动结构。
由于补液瓶是倒置安装的，在更换补液瓶时，如果内部还有皂液，会造成皂液的溅出，本方案在瓶口设置了补液阀结构，如果补液顶动结构顶动补液阀结构才可使得瓶口打开，而当补液顶动结构与补液阀结构分离后，补液阀结构就关闭瓶口，从而避免皂液溅出的现象。
具体地：所述补液阀结构包括套设于瓶口的补液阀盖、呈上下延伸设置的补液阀芯杆，所述补液阀盖设置有补液阀口，在所述补液阀芯杆与补液阀盖之间设置有补液弹性件，在所述补液阀芯杆的外周壁设置有封堵台阶，所述补液弹性件用于给补液阀芯杆提供向下的作用力而使所述封堵台阶封堵所述补液阀口，所述补液阀芯杆的下端从补液阀口伸出并与所述补液顶动结构抵触。
本方案中的补液阀结构在自由的状态下，补液弹性件使所述封堵台阶封堵所述补液阀口，而当补液阀芯杆的下端与所述补液顶动结构 抵触，并往上顶动补液阀芯杆时，封堵台阶就与补液阀口分离，这样补液阀口处于贯通的状态。
其中在所述补液阀盖的内侧固定设置有导向架，所述导向架设置有与所述补液阀芯杆上端上下滑动配合的第一导向孔，所述补液阀芯杆外周设置有抵触台阶，所述补液弹性件作用于设置于抵触台阶与第一导向孔底部之间。
所述补液顶动结构包括设置于补液槽槽底的补液顶动台，所述补液弹性件为套设于补液阀芯杆外周的弹簧。
作为上述技术方案的进一步改进，所述泡沫发生机构还包括泡沫细化单元，所述泡沫细化单元通过管道于混合通道的出口连接，所述供气泵单元包括供气泵，所述供气泵通过气管与进气口连接。
本方案还设置了泡沫细化单元对皂液与气体的混合体进行泡沫细化。
作为上述技术方案的进一步改进，所述补液单向阀包括呈延伸设置的伞形阀芯、设置于混气槽腔顶部的补液通孔和第二导向孔，所述伞形阀芯包括阀帽、阀杆，所述阀杆与所述第二导向孔上下滑动配合，所述补液通孔设置于阀帽的下方，所述补液通孔与所述补液槽连通，所述补液通孔的数量为多个，多个所述补液通孔以阀杆的轴线为中心呈环形间隔设置。
本方案中的补液单向阀通过伞形阀芯的结构来实现，其中阀杆与第二导向孔滑动配合，在自由的状态下，伞形阀芯依靠自身的重力往下移动，这时的阀帽封堵补液通孔，而当进行供液时，液体会往上顶动伞形阀芯，这时的阀帽打开补液通孔，其中阀杆的下端设置有限位凸起，可避免伞形阀芯从第二导向孔上脱离。多个所述补液通孔可提高供液的速度。
在其他方案中，补液单向阀还可为电磁阀、单向阀等流体控制装 置。

参照图1至图5，本发明的下置大容量单气泵泡沫发生装置作出如下实施例：
本实施例的下置大容量单气泵泡沫发生装置包括补液机构和泡沫发生机构。
其中补液机构包括补液槽100、补液瓶200，所述补液槽100设置有开口朝上的套装口110，所述补液瓶200的下端从所述套装口110套设于补液槽100内，所述补液槽100与外界连通，所述补液瓶200的下端设置有瓶口。
泡沫发生机构包括供气泵单元、混气槽腔300，设置于混气槽腔300上部的气液混合结构、进气口310和通气阀结构320，所述混气槽腔300的下部与补液槽100的下部连通，在所述混气槽腔300与补液槽100之间设置有补液单向阀400，所述补液单向阀400的连通方向为从补液槽100往混气槽腔300的方向，所述供气泵单元与进气口310连接，所述通气阀结构320将所述混气槽腔300与外界连通，所述气液混合结构设置有出液通道330、出气通道340、混合通道350，所述出液通道330的进口端往下延伸至混气槽腔300的底部内，所述出气通道340的进口端和进气口310均与混气槽腔300的上部连通，所述出液通道330的出口端和出气通道340和出口端分别与混合通道350的进口连通。
其中本实施例中的所述供气泵单元包括供气泵800，所述供气泵800通过气管与进气口310连接，并且还设置有泡沫细化单元700，所述泡沫细化单元700通过管道于混合通道350的出口连接。
当需要喷出泡沫时，供气泵单元给混气槽腔300进行空气加压，使混气槽腔300内部压强增大，这时的通气阀结构320关闭，混气槽的皂液受压强作用下从出液通道330进入混合通道350，同时混气槽 腔300内的气体也在压强的作用下从出气通道340进入混合通道350，气体与皂液在混合通道350内混合形成泡沫后一同从混合通道350喷出，实现泡沫的喷出；当混气槽腔300内的皂液被喷出后，混气槽腔300内皂液的液面会降低，这时补液槽100内的皂液在大气压强的作用下，通过补液单向阀400供入混气槽腔300内，直至混气槽腔300与补液槽100达到气压平衡，即是混气槽腔300与补液槽100的液面高度一致，这时的通气阀结构320保持打开状态，将所述混气槽腔300与外界连通；以及在补液槽100内的皂液供给混气槽腔300的同时，由于补液瓶200下端的瓶口从所述套装口110套设于补液槽100内，补液槽100的液面降低，补液瓶200中的皂液会补充入补液槽100，直至补液槽100内的液面高度没过瓶口时，停止补液，从而确保补液槽100内部的皂液量，本泡沫发生装置通过单个供气泵单元即可实现泡沫的产生，并且在大气压的作用下，补液瓶200、补液槽100与混气槽腔300之间通过机械式的结构即可实现自动的供液、补液，实现大容量的使用，无需频繁进行补液。
其中，所述通气阀结构320包括将所述混气槽腔300与外界连通的通气腔道321、上下活动设置于通气腔道321内的配重堵塞体322，所述通气腔道321设置有呈上下设置的通气出气端323和通气进气端324，所述配重堵塞体322用于受所述混气槽腔300内高压气体的作用力而往上移动至封堵所述通气出气端323。本实施例通气阀结构320通过配重堵塞体322来实现机械式的闭合，在补液槽100对混气槽腔300进行供液时，混气槽腔300内的气压比较低的，这时的配重堵塞体322会被气压往上顶，但是没有顶到封堵通气出气端323，使得通气腔道321处于贯通的状态，这时的混气槽腔300就于外界连通，补液槽100可对混气槽腔300进行供液；而当供气泵单元给混气槽腔300进行空气加压，混气槽腔300内气压很高，高压气体会往上顶动 配重堵塞体322，使得配重堵塞体322封堵所述通气出气端323，这时的通气腔道321处于关闭的状态，泡沫发生装置处于喷泡沫的状态。其中配重堵塞体322的重量，本领域技术人员可根据实际的工作气压而定，本发明不进行详细的阐述。
并且在所述通气进气端324设置有用于承托配重堵塞体322的环形承载台阶325，所述配重堵塞体322呈球状。环形承载台阶325主要起到承托配重堵塞体322的作用，避免配重堵塞体322往下掉落，以及确保配重堵塞体322可被气体往上顶动，其中通气出气端323呈上小下大喇叭状结构。球状的配重堵塞体322与通气腔道321内壁之间形成有通气间隙。
而本实施例的所述气液混合结构包括设置于混气槽腔300顶部内的套接凹槽360、套设于套接凹槽360内的呈中空的套接件370，所述混合通道350设置于套接凹槽360的顶部并与所述套接凹槽360连通，所述出气通道340设置于套接件370的外壁与套接凹槽360的内壁之间，所述套接件370连接有出液管371，所述出液通道330形成于出液管371和套接件370内，在结构上更为简单，无需采用很复杂的模具制造而成。
并且，所述出气通道340的数量为多个，多个出气通道340呈环形间隔设置于套接件370的外壁与套接凹槽360的内壁之间，多个出气通道340可使得气体与皂液的混合更加均匀充分，气体从混合通道350的四周进入，并与皂液进行混合。
更进一步地，由于补液瓶200是倒置安装的，在更换补液瓶200时，如果内部还有皂液，会造成皂液的溅出，为了避免皂液溅出的现象，所述瓶口设置有补液阀结构，所述补液槽100设置有用于与补液阀结构抵触而使所述补液阀结构打开的补液顶动结构，如果补液顶动结构顶动补液阀结构才可使得瓶口打开，而当补液顶动结构与补液阀 结构分离后，补液阀结构就关闭瓶口。具体地：所述补液阀结构包括套设于瓶口的补液阀盖500、呈上下延伸设置的补液阀芯杆510，所述补液阀盖500设置有补液阀口520，在所述补液阀芯杆510与补液阀盖500之间设置有补液弹性件530，在所述补液阀芯杆510的外周壁设置有封堵台阶511，所述补液弹性件530用于给补液阀芯杆510提供向下的作用力而使所述封堵台阶511封堵所述补液阀口520，所述补液阀芯杆510的下端从补液阀口520伸出并与所述补液顶动结构抵触。
补液阀结构在自由的状态下，补液弹性件530使所述封堵台阶511封堵所述补液阀口520，而当补液阀芯杆510的下端与所述补液顶动结构抵触，并往上顶动补液阀芯杆510时，封堵台阶511就与补液阀口520分离，这样补液阀口520处于贯通的状态。
其中在所述补液阀盖500的内侧固定设置有导向架540，所述导向架540设置有与所述补液阀芯杆510上端上下滑动配合的第一导向孔531，所述补液阀芯杆510外周设置有抵触台阶512，所述补液弹性件530作用于设置于抵触台阶512与第一导向孔531底部之间。
本实施例中的补液顶动结构包括设置于补液槽100槽底的补液顶动台600，所述补液弹性件530为套设于补液阀芯杆510外周的弹簧。
而本实施例中的所述补液单向阀400包括呈延伸设置的伞形阀芯、设置于混气槽腔300顶部的补液通孔410和第二导向孔420，所述伞形阀芯包括阀帽430、阀杆440，所述阀杆440与所述第二导向孔420上下滑动配合，所述补液通孔410设置于阀帽430的下方，所述补液通孔410与所述补液槽100连通，所述补液通孔410的数量为多个，多个所述补液通孔410以阀杆440的轴线为中心呈环形间隔设置。补液单向阀400通过伞形阀芯的结构来实现，其中阀杆440与第 二导向孔420滑动配合，在自由的状态下，伞形阀芯依靠自身的重力往下移动，这时的阀帽430封堵补液通孔410，而当进行供液时，液体会往上顶动伞形阀芯，这时的阀帽430打开补液通孔410，其中阀杆440的下端设置有限位凸起，可避免伞形阀芯从第二导向孔420上脱离。多个所述补液通孔410可提高供液的速度。
在其他一些实施例中，补液单向阀400可采用其他单向阀结构，可实现液体的单向通过即可。
在其他一些实施例中，通气阀结构320也可采用其他结构，例如可采用微型通气孔结构900，其中混气槽腔300通过微型通气孔结构900与外环境连通，在供气泵单元不工作时，起到气压平衡，补液排气作用；在供气泵单元给混气槽腔300加压时，会有少量空气从微型通气孔结构900排出，但这些少量空气可忽略不记，不影响泡沫喷出。如图6所示，在所述混气槽腔300上部的外壁固定设置有套筒910，在所述套筒910内设置有固定于混气槽腔300外壁上的套接柱920，所述套筒910与套接柱920之间形成套接间隙930，在所述套接间隙930的底部设置有与混气槽腔300连通的通气槽口940，所述套接间隙930套设有倒置桶状的通气套950，所述通气套950的顶部设置有微型通气孔结构900，所述通气套950的外周壁与套筒910的内周壁密封抵触，而通气套950的内壁与套接柱920的外壁之间形成多个通气槽道960，所述通气槽道960的两端分别与微型通气孔结构900、通气槽口940连通。
以上对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
