具体实施方式
为了便于理解本发明，下面结合附图和实施例对本发明进行进一步的说明。
在本发明的描述中，需要说明的是，术语“前”、“后”、“左”、“右”、“上”、“下”、“内”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述，而不是指示或暗示所指的装置或部件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
如图1至图11所示，本发明所公开的气压调整装置的主体结构为基体100，在基体100内部设有保压通道200和三通腔体300。保压通道200可作为气压调整装置的气体通道，在保压通道200上设有保压通道进气口210和第一排气通道220，保压通道进气口210和第一排气通道220都可进行开闭；通过保压通道进气口210或三通腔体300可将气体输送至保压通道200内；通过第一排气通道220则可对保压通道200进行排气。在基体100内部设有与各个三通腔体300一一对应的导流腔310，导流腔310与相对应的三通腔体300连通，并且导流腔310再与固定在基体100上的气囊连接管道400连通，导流腔310同样可进行开闭；气囊连接管道400用于与气压按摩仪中的气囊连接或与其他带有类似气囊结构设备进行连接。三通腔体300上连接导流腔310和连接保压通道200的部位不同，以图11为例，保压通道200与三通腔体300的下部连通，则导流腔310与三通腔体300的上部连通。
本发明所公开的气压调整装置对气囊800进行保压的重要部件在于设置在各个三通腔体300与保压通道200连接处的单向阀320，同时限定单向阀320从三通腔体300指向保压通道200的方向开启。本发明通过气压调整装置实现保压的原理为：向气压调整装置的保压通道200内充气，保压通道200内的气压不断增加，由于单向阀320受到开启方向的限制，气体只能从三通腔体300方向通过单向阀320向保压通道200方向流动而不能从保压通道200方向通过单向阀320向三通腔体300方向流动，则单向阀320被高压气体顶压关闭，保压通道200内的气压不断上升，直至达到预设的气压值后将保压通道进气口210关闭，保压通道200内的高压气体不能排出而维持稳定的气压值；此时只有当三通腔体300内的气压值大于保压通道200内的气压值时，单向阀320才能打开，只要将保压通道200内的压力值设定为大于三通腔体300内的最大气压值，三通腔体300与气囊800通过气囊连接管道400连通后将三通腔体300关闭，则在不主动打开保压通道200进行排气泄压的情况下，气囊800和三通腔体300内的气压值会一直保持稳定，最终达到预充保压的效果。
本发明中气压调整装置根据对保压通道200采取不同的充气方式可采用以下两种不同的实施结构：
气压调整装置的第一种实施例如图1至图4、图7和图8所示，由气囊800通过三通腔体300对保压通道200进行充气，此实施例中保压通道进气口210不需要作为气体的进口使用，因此设置为常闭状态，为了简化结构可直接将保压通道进气口210封闭或直接将保压通道进气口210省略；在对保压通道200进行充气保压时，预先向其中一个或多个气囊800进行充气，在气囊800充气后停止气体输入，关闭对气囊800充气的通道并连通气囊800与相对应三通腔体300之间的通道，由于气囊800充气后气压增加，气囊800内的气体会向低压方向流动，则气囊800中的气体进入三通腔体300然后穿过单向阀320进入保压通道200中，由于单向阀320开启方向的限制，气体只能从三通腔体300方向通过单向阀320向保压通道200方向流动而不能从保压通道200方向通过单向阀320向三通腔体300方向流动，保压通道200内的气压不断增加，直至保压通道200中的气压达到预设的气压值后，单向阀320被保压通道200中的气体顶压关闭，保压通道200形成密封的通道，保压通道200内的高压气体不能排出而维持稳定的气压值；此时只有当三通腔体300内的气压值大于保压通道200内的气压值时，单向阀320才能打开，只要将保压通道200内的预设压力值设定为大于三通腔体300内的最大气压值即大于气囊800的最大充气气压值，三通腔体300与气囊800连通后，在不主动打开保压通道200进行排气泄压的情况下，气囊800和三通腔体300内的气压值会一直保持稳定，最终达到预充保压的效果。
气压调整装置的第二种实施例如图1、图2、图5、图6、图9和图10所示，由外接气源 通过保压通道进气口210对保压通道200进行充气保压，此实施例中保压通道进气口210作为气体的进口使用，因此保压通道进气口210需要打开并与外接气源连通。在对保压通道200进行充气保压时，由外接气源通过保压通道进气口210向保压通道200内充气，保压通道200内的气压不断增加，由于单向阀320受到开启方向的限制，气体只能从三通腔体300方向通过单向阀320向保压通道200方向流动而不能从保压通道200方向通过单向阀320向三通腔体300方向流动，则单向阀320被高压气体顶压关闭，保压通道200内的气压不断上升，直至达到预设的气压值后将保压通道进气口210关闭，保压通道200内的高压气体不能排出而维持稳定的气压值；此时只有当三通腔体300内的气压值大于保压通道200内的气压值时，单向阀320才能打开，只要将保压通道200内的压力值设定为大于三通腔体300内的最大气压值，三通腔体300与气囊800通过气囊连接管道400连通后将三通腔体300关闭，则在不主动打开保压通道200进行排气泄压的情况下，气囊800和三通腔体300内的气压值会一直保持稳定，最终达到预充保压的效果。
如上述内容所述，本发明中的导流腔310和第一排气通道220都可进行开闭，具体的，导流腔310和第一排气通道220的开闭都采用电磁阀进行控制，导流腔310的开闭由气腔电磁阀500控制，而第一排气通道220的开闭则由第一排气电磁阀230控制；气腔电磁阀500的数量与导流腔310一致且一一对应，气腔电磁阀500和第一排气电磁阀230都安装在基体100上。
如图1至图11所示，本发明中气压调整装置所采用的基体100包括下座110和中框120。下座110为气腔电磁阀500和第一排气电磁阀230的固定部位，多个三通腔体300沿下座110的长度方向间隔排布并设置在下座110内部。中框120可拆卸固定在下座110的顶部，中框120与下座110之间的装配可通过紧固件连接、卡扣结构连接等多种现有的连接方式实现。多个导流腔310则沿中框120的长度方向间隔排布并设置在中框120内部，下座110和中框120装配后，导流腔310位于相对应三通腔体300的上方并与相对应的三通腔体300连通。作为优选方案，本发明中三通腔体300可用于安装气腔电磁阀500，气腔电磁阀500的阀座顶部固定在相对应的三通腔体300内，气腔电磁阀500的活塞端穿过相对应的三通腔体300并伸入上方的导流腔310内，气腔电磁阀500通过活塞端的升降来实现对导流腔310的开闭，气腔电磁阀500活塞端的尺寸大于导流腔310与三通腔体300相连接处的孔径，则当气腔电磁阀500的活塞端下降至导流腔310与三通腔体300的相连处时即可将导流腔310与三通腔体300隔绝，导流腔310与三通腔体300之间不能进行气体流通。此外，在中框120内部还设有进排气通道130，进排气通道130用于实现导流腔310与气囊连接管道400的连通，进排气通道130与导流腔310为一一对应关系；气囊连接管道400固定在中框120的顶面上， 气囊连接管道400的底部伸入中框120内与相对应的进排气通道130连通。气囊连接管道400用于进行气压调整装置与气压按摩仪中气囊800的连接，为了便于实现气囊连接管道400与气囊800之间的连接，可采用圆锥形管道作为气囊连接管道400，并且限定气囊连接管道400与进排气通道130相连通一端的外径大于另一端的外径，则可通过卡插的方式快速、便捷的进行气囊连接管道400与气囊800的连接。
此外，在针对气囊充气过程中的串气问题时，也可通过单独在导流腔310中增加单向阀的方案来解决，利用单向阀来控制导流腔310与充气通道180之间的连通状态。具体的，采用数量与气囊一致的单向阀，将单向阀设置在导流腔310与充气通道180的连通处，限定单向阀从充气通道180指向导流腔310的方向开启。在对气囊进行充气时，由外接气源通入充气通道180中的高压气体冲开单向阀，依次通过导流腔310、进排气通道130和气囊连接管道400后向对应的气囊800进行充气；当气囊800中的压力达到或接近充气通道180中的压力值时，导流腔310与充气通道180之间的单向阀由于两侧压力变的平衡而自动关闭，单向阀关闭后由于气囊800中的压力较大，只要充气通道180中的压力不再增加，导流腔310与充气通道180之间的单向阀变不会打开，从而能够保持气囊800中的压力稳定。具体的，当需要对第一气囊801进行充气，第一气腔电磁阀501开启，来自充气通道180的高压气体顶开第一导流腔311中的单向阀，对第一气囊801进行充气，充气完成后第一气囊801气体压力高于充气通道180中的气体压力，反推第一导流腔311中的单向阀关闭；然后对第二气囊802进行充气，第二气腔电磁阀502开启，来自充气通道180的高压气体顶开第二导流腔312中的单向阀，对第二气囊802进行充气；由于第一导流腔311中的单向阀只能单向导通，第一气囊801中的高压气体不会顶开第一导流腔311中的单向阀而回流到充气通道180中，第一气囊801中的气体就不会串入第二气囊802内。同理，在分别对第三气囊803、第四气囊804以及第五气囊805进行充气时，只需打开相应的第三气腔电磁阀503，第四气腔电磁阀504以及第五气腔电磁阀505即可，已经充好气的第二气囊802、第三气囊803、第四气囊804所对应的单向阀会自行关闭，不会出现气囊间串气的问题。
如图2、图10和图11所示，本发明中三通腔体300与保压通道200之间的连通依靠设置在下座110内的排气通道140来实现，排气通道140与三通腔体300为一一对应关系，排气通道140设置在相对应的三通腔体300与保压通道200之间，而单向阀32则设置在排气通道140与保压通道200的连接处，单向阀320从排气通道140指向保压通道200的方向开启，即气体可从排气通道140方向通过单向阀320向保压通道200方向流动而不能从保压通道200方向通过单向阀320向排气通道140方向流动。
如图2、图3、图5和图6所示，为了实现单向阀320的安装，本发明中气压调整装置的 基体100还包括单向阀固定板160，单向阀固定板160可通过紧固件连接或卡扣结构连接等方式可拆卸连接在下座110的侧面，在单向阀固定板160上固定有多个第一安装半腔161，同时，在下座110的侧面上固定有多个于第一安装半腔161相对应的第二安装半腔162，第二安装半腔162通过排气通道140与下座110内相对应的三通腔体300连通。单向阀固定板160与下座110装配后，第一安装半腔161和第二安装半腔162对接组成容纳单向阀320的腔体。此处，单向阀320采用单片对夹式止回阀，通过气体对单向阀320的压力将单向阀320单向冲开以实现单向阀320的开启。
本发明中的保压通道200由设置在基体100上的密封侧盖板170和单向阀固定板160装配形成，如图2、图3、图5和图6所示，在单向阀固定板160上设有沿单向阀固定板160长度方向延伸的保压通道槽163，保压通道槽163与单向阀固定板160上的各个第一安装半腔161连通，将密封侧盖板170连接在单向阀固定板160未与下座110相连接的一面上并通过密封侧盖板170将保压通道槽163完全覆盖并密封，则保压通道槽163与密封侧盖板170配合形成了保压通道200。
将气压调整装置与气压按摩仪进行装配后，为了简化结构、节约所占用的空间，本发明中将气囊800的充气通道和排气通道都集成到气压调整装置上。如图4、图6至图10所示，在基体100上设有气路通道180和第二排气腔体190，气路通道180上设有气路通道进气口，气路通道进气口用于与气源连通进行充气；气路通道180与各个三通腔体300的导流腔310连通，且第二排气腔体190与气路通道180连通，在第二排气腔体190未与气路通道180相连通处还连通有第二排气通道191。第二排气腔体190可进行开闭，第二排气腔体190打开时，第二排气腔体190与气路通道180连通，气囊800中的气体可通过气路通道180进入第二排气腔体190中并通过第二排气通道191排出，从而实现对气囊800的放气，此时气路通道180可作为排气通道使用；第二排气腔体190关闭时，第二排气腔体190与气路通道180隔绝开，气路通道180中的气体无法进入第二排气腔体190中，此时气路通道180只能作为充气通道使用。本发明通过设置气路通道180、第二排气腔体190和第二排气通道191，可选择对单个气囊800进行放气，从而实现对单个气囊800内的气压进单独行调节。
如前述的导流腔310的开闭原理一样，本发明中采用第二排气电磁阀192来控制第二排气腔体190的开闭，如图3至图6所示，第二排气电磁阀192固定在下座110的底部且第二排气电磁阀192的活塞端伸入第二排气腔体190内。第二排气电磁阀192通过活塞端的升降来实现对进第二排气腔体190的开闭，第二排气电磁阀192活塞端的尺寸大于第二排气腔体190与气路通道180相连接处的孔径，则当第二排气电磁阀192的活塞端上升至第二排气腔体190与气路通道180相连接处时即可将第二排气腔体190与气路通道180隔绝，第二排气 腔体190关闭，此时第二排气腔体190与气路通道180之间不能进行气体流通；当第二排气电磁阀192的活塞端下降后，第二排气电磁阀192的活塞端不再将第二排气腔体190与气路通道180隔绝，第二排气腔体190打开，此时气路通道180中的气体能够进入第二排气腔体190中，并可通过第二排气通道191排出。
具体的，如图1至图11所示，本发明中的气路通道180由设置在基体100上的上盖150和中框120装配形成，上盖150的其中一面上设有沿上盖150长度方向延伸的气路通道槽，将上盖150设有气路通道槽的一面与中框120的顶面相对并进行连接，使气路通道槽与第二排气腔体190以及各个导流腔310连通，中框120将上盖150上的气路通道槽完全覆盖并密封，则中框120与上盖150相接的一面与气路通道槽密封配合形成了气路通道180。
如图1至图3、图5所示，气囊连接管道400固定在中框120的顶面上，可在上盖150上开设让位孔151以对气囊连接管道400进行让位，让位孔151与气囊连接管道400一一对应，气囊连接管道400从上盖150上相对应的让位孔151中穿过。
如图1、图9和图10所示，本发明中在基体100的一端延伸出基体延伸部600来设置保压通道进气口210、第一排气通道220和第一排气电磁阀230。基体延伸部600由上盖延伸部610、中框延伸部620和下座延伸部630组成，中框延伸部620通过紧固件连接或卡扣结构连接等连接方式可拆卸连接在上盖延伸部610和下座延伸部630之间。保压通道进气口210设置在上盖延伸部610内，中框延伸部620内设有同时与保压通道进气口210以及第一排气通道220连通的第一排气腔体631，第一排气腔体631由保压通道200延伸至中框延伸部620内部形成。本发明中采用第一排气电磁阀230来控制第一排气通道220的开闭，第一排气电磁阀230固定在下座延伸部630的底部且第一排气电磁阀230的活塞端伸入第一排气腔体631内。由于第一排气通道220与第一排气腔体631连通，则第一排气电磁阀230可通过活塞端的升降来实现对第一排气通道220的开闭；第一排气电磁阀230活塞端的尺寸大于第一排气通道220与第一排气腔体631相连接处的孔径，当第一排气电磁阀230的活塞端下降至第一排气通道220与第一排气腔体631连接处时即可将第一排气通道220与第一排气腔体631隔绝，第一排气通道220关闭，此时与第一排气腔体631连通的保压通道200与第一排气通道220之间不能进行气体流通，则保压通道200中的气体无法通过第一排气通道220排出；当第一排气电磁阀230的活塞端上升，第一排气通道220与第一排气腔体631连接处不再被第一排气电磁阀230的活塞端封闭，第一排气通道220打开，此时保压通道200中的气体能够通过第一排气腔体631进入第一排气通道220中，并可通过第一排气通道220排出。
上述内容中提到，本发明中的保压通道进气口210可进行开闭，气压调整装置的第一种实施例中保压通道进气口210为常闭状态，而气压调整装置的第二种实施例中保压通道进气 口210需要在充气保压时打开与外接气源连通，并且在充气完成后的保压过程中保持关闭状态；具体的，在气压调整装置的第二种实施例中，依靠设置在保压通道进气口210内的进气单向阀240来实现保压通道进气口210的自动开闭，进气单向阀240控制保压通道进气口210的开闭，进气单向阀240从保压通道进气口210外侧指向第一排气腔体631的方向开启。由气源通过保压通道进气口210向保压通道200内输送气体时，由于限定了进气单向阀240的开启方向，气体可从保压通道进气口210与气源连通的一侧通过进气单向阀240进入第一排气腔体631中，随着保压通道200内气压不断增加，当保压通道200内部的气压值达到设定的数值时，关闭气源停止送气，则进气单向阀240在保压通道200内部压力作用下自动关闭，实现对保压通道进气口210的关闭，再配合单向阀320和第一排气电磁阀230的共同作用即可实现对保压通道200的完全封闭，维持保压通道200内的气压保持不变，从而实现保压的效果。
基体延伸部600可与基体100采用一体结构以简化气压调整装置的整体结构、减小占用空间，即上盖延伸部610与上盖150为一体结构，中框延伸部620与中框120为一体结构，下座延伸部630与下座110为一体结构。
本发明中，第一排气电磁阀230、第二排气电磁阀192和气腔电磁阀500都采用常闭电磁阀，采用常闭电磁阀时电磁阀通电时为开启状态、断电时为关闭状态，从而能够在断电时将所有气囊和通道内的气体排出，且能够有效降低电磁阀的电力耗费，达到节能省电的效果。
进一步的，为了提高电磁阀对各个腔体的封闭效果，可在第一排气电磁阀230、第二排气电磁阀192和气腔电磁阀500的活塞端端头都设置密封帽，密封帽以采用弹性良好的硅胶密封帽为最优选择。
本发明还公开了包含上述气压调整装置的气压按摩仪，如图7至图10所示，气压按摩仪包括气源700和多个气囊800，通过气源700可向气囊800充气以使气囊800膨胀。气压调整装置的基体100可直接安装在气压按摩仪原有控制组件上，从而将气压调整装置、控制组件和气源700都集成在一起。气压按摩仪上气囊800与气压调整装置中的三通腔体300一一对应，气囊800与相对应的气囊连接管道400连接，由于气囊800与气囊连接管道400之间不易进行连接，可采用连接管810作为气囊800与气囊连接管道400之间的中继管道，连接管810以采用连接软管作为最优选择，在装配时可对连接软管进行折弯以减小占用空间。在气压调整装置的第二种实施例中，如图9和图10所示，气源700通过第一充气通道710与保压通道进气口210连通，且气源700通过第二充气通道720与气路通道180的气路通道进气口连通，进而实现气源700与气压调整装置中各个三通腔体300的导流腔310之间的连通；在气压调整装置的第一种实施例中，如图7和图8所示，气源700只通过第二充气通道720 与气路通道180的气路通道进气口连通，进而实现气源700与气压调整装置中各个三通腔体300的导流腔310之间的连通，此实施例中由于保压通道200不需要直接由气源700供气，因此保压通道进气口210关闭，气源700与保压通道进气口210之间不需要直接设置连通结构。
气源700一般采用常用的气泵，气源700的数量可为两个，第一充气通道710和第二充气通道720分别连通在两个气源700上。为了简化结构、节约成本，可只采用一个气源700，在气压调整装置的第二种实施例中，利用三通接头730来实现气源700同时与第一充气通道710和第二充气通道720的连通，即将三通接头730的进口端与气源700的出口端连通，将三通接头730的两个出口端分别与第一充气通道710的进口端以及第二充气通道720的进口端连通。
由于气压按摩仪的控制组件需要根据对各个通道内的气压值来控制各个电磁阀的开闭以进行气压调整装置的保压、均压或泄压工作，为了便于对气压值进行准确监控，本发明中在气源700与气压按摩仪之间的管路上设置了压力传感器740，压力传感器740与气压按摩仪的控制组件电气连接，压力传感器740可将监控的气压值数据传输给气压按摩仪的控制组件。
此发明中气压按摩仪设有五个气囊800，气囊800包括第一气囊801、第二气囊802、第三气囊803、第四气囊804和第五气囊805；相应的，三通腔体300、导流腔310、单向阀320、气囊连接管道400和气腔电磁阀500的数量都为五个。即三通腔体300包括第一三通腔体301、第二三通腔体302、第三三通腔体303、第四三通腔体304和第五三通腔体305；导流腔310包括第一导流腔311、第二导流腔312、第三导流腔313、第四导流腔314和第五导流腔315；单向阀320包括第一单向阀321、第二单向阀322、第三单向阀323、第四单向阀324、和第五单向阀325；气囊连接管道400包括第一气囊连接管道401、第二气囊连接管道402、第三气囊连接管道403、第四气囊连接管道404和第五气囊连接管道405；气腔电磁阀500包括第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504和第五气腔电磁阀505。
设有气压调整装置的气压按摩仪可实现预充保压、保压按摩、均压及调压、断电自动泄压的功能；由于气压调整装置两种实施例中保压通道200的充气方式不同，因此预充保压的过程存在差异，而保压按摩、均压及调压和断电自动泄压的过程相同。具体功能说明如下：
1)预充保压
气压调整装置的第一种实施例中，
如图12和图13所示，第一气腔电磁阀501和第一排气电磁阀220通电打开，第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504、第五气腔电磁阀505以及第二排气 电磁阀192都为断电关闭状态。
启动气源700通过第二充气通道720向气路通道180中充气，此时气路通道180与第一导流腔311连通，第一导流腔311与第一三通腔体301隔绝，气体只能进入第一导流腔311中并经过第一气囊连接管道401进入第一气囊801中。第一气囊801充气完成后，如图14和图15所示，关闭气源700并使第一气腔电磁阀501断电关闭，则第一导流腔311与气路通道180隔绝而与第一三通腔体301连通，第一气囊801中的高压气体流入第一三通腔体310中，并顶开第一单向阀321进入保压通道200中，当保压通道200中的气压增加到预设的气压值Pa时，重新对第一气腔电磁阀501通电使其打开，则第一导流腔311与第一三通腔体301再次隔绝，保压通道200中的高压气体将第一单向阀321顶压关闭，保压通道200形成维持气压值Pa的密封通道。
保压通道200充气完成后，第一单向阀321、第二单向阀322、第三单向阀323、第四单向阀324、和第五单向阀325都处于关闭状态，同时保压通道200内的气压值达到预设的Pa，只要气囊800设定的最大充气气压值Pb小于保压通道200内的气压值Pa，则可通过压力差使各个单向阀320都持续保持关闭状态，后续向气囊800内进行充气时也可在各气腔电磁阀500不通电的情况下阻止已充气气囊内的气体回流，进而杜绝了串气现象的发生，同时能够降低各个电磁阀的能耗。
气压调整装置的第二种实施例中，
如图16和图17所示，第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504、第五气腔电磁阀505以及第二排气电磁阀192都为断电关闭状态，此时，第一导流腔311、第二导流腔312、第三导流腔313、第四导流腔314、第五导流腔315和第二排气腔体190都与气路通道180隔绝。
打开第一排气电磁阀230并启动气源700，由于各个气腔电磁阀500将对应的导流腔310都关闭，气源700无法通过导流腔310向各个气囊800内充气。气源700通过第一充气通道710向气压调整装置内送气，由于第一排气电磁阀230为打开状态，第一排气腔体631与保压通道进气口210连通的同时与第一排气通道220隔绝，气体可冲开进气单向阀240进入第一排气腔体631中，并接着保压通道200中。然后气体分别冲向各个单向阀320，各个单向阀320受压关闭，保压通道200与各个三通腔体300之间被单向阀320隔绝而无法进行气体流通，气体在保压通道200内不断充气增压，当压力传感器740监控到保压通道200内的气压值上升至预设的压力值Pa后，气源700停止送气；此时进气单向阀240两侧存在压力差，进气单向阀240受压关闭，整个保压通道200完成封闭，保压通道200内的气压值维持为Pa保持不变。
通过上述流程，使第一单向阀321、第二单向阀322、第三单向阀323、第四单向阀324、和第五单向阀325都处于关闭状态，同时保压通道200内的气压值达到预设的Pa，只要气囊800设定的最大充气气压值Pb小于保压通道200内的气压值Pa，则可通过压力差使各个单向阀320持续保持关闭状态，后续向气囊800内进行充气时也可在各气腔电磁阀500不通电的情况下阻止已充气气囊内的气体回流，进而杜绝了串气现象的发生，同时能够降低各个电磁阀的能耗。
2)保压按摩
如图18和图19所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，第一气腔电磁阀501通电打开，第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504、第五气腔电磁阀505和第二排气电磁阀192保持断电关闭状态。启动气源700通过第二充气通道720向气路通道180内送气，气体进入第一导流腔311中。由于第一气腔电磁阀501为打开状态，第一导流腔311和第一三通腔体301相隔绝无法进行气体流通，气体只能通过与第一导流腔311连通的第一气囊连接管道401进入第一气囊801中。当压力传感器740监控到第一导流腔311内的气压值Pb1达到气囊的最大充气气压值Pb时，气源700停止充气，第一气腔电磁阀501断电关闭，第一导流腔311和气路通道180隔绝，第一气囊连接管道401通过第一导流腔311与第一三通腔体301连通，但由于保压通道200内的气压值Pa大于第一导流腔311内的气压值Pb1，第一单向阀321无法被冲开，第一气囊801中的气体则无法流动，从而实现了对第一气囊801的保压。
同理，如图20和图21所示，第二气腔电磁阀502通电打开，第一气腔电磁阀501、第三气腔电磁阀503、第四气腔电磁阀504、第五气腔电磁阀505和第二排气电磁阀192保持断电关闭状态。启动气源700对第二气囊802进行充气，第二导流腔312内的气压值Pb2达到气囊的最大充气气压值Pb时，气源700停止充气，气压调整装置对第二气囊802保压。
同理，如图22和图23所示，第三气腔电磁阀503通电打开，第一气腔电磁阀501、第二气腔电磁阀502、第四气腔电磁阀504、第五气腔电磁阀505和第二排气电磁阀192保持断电关闭状态。启动气源700对第三气囊803进行充气，第三导流腔313内的气压值Pb3达到气囊的最大充气气压值Pb时，气源700停止充气，气压调整装置对第三气囊803保压。
同理，如图24和图25所示，第四气腔电磁阀504通电打开，第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503、第五气腔电磁阀505和第二排气电磁阀192保持断电关闭状态。启动气源700对第四气囊804进行充气，第四导流腔314内的气压值Pb4达到气囊的最大充气气压值Pb时，气源700停止充气，气压调整装置对第四气囊804保压。
同理，如图26和图27所示，第五气腔电磁阀505通电打开，第一气腔电磁阀501、第 二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504和第二排气电磁阀192保持断电关闭状态。启动气源700对第五气囊805进行充气，第五导流腔315内的气压值Pb5达到气囊的最大充气气压值Pb时，气源700停止充气，气压调整装置对第五气囊805保压。
当所有气囊800充气完成后，所有气腔电磁阀500都为断电关闭状态，电磁阀的电耗降至最低。充气完成后即可通过气囊800对肢体和肌肉组织的按压按摩。
另外，可向不同气囊800内充入不同量的气体以使各个气囊800内的气压值不等同，即Pb1≠Pb2≠Pb3≠Pb4≠Pb5，只要各个气囊800内的气压值都小于保压通道200内的保压气压值Pa，就能一致维持保压状态。从而可使各个气囊800具有不同的膨胀程度，能够对不同按摩部位进行不同力度的按压，为用户带来更好的按摩体验。
3)均压及调压
如图28和图29所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，气源700停止充气。第一气腔电磁阀501和第二排气电磁阀192通电打开，第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504和第五气腔电磁阀505保持断电关闭状态。此时，由于第一气腔电磁阀501为打开状态，第一气囊801中的气体能够通过第一气囊连接管道401进入第一导流腔311中，由于第一导流腔311和第一三通腔体301隔绝，但第一导流腔311和气路通道180连通，进入第一导流腔311中的气体则只能够进入气路通道180中。气体在气路通道180中流动时，由于除开第一气腔电磁阀501外的其他气腔电磁阀500都为断电关闭状态，而第二排气电磁阀192为通电打开状态，气体无法进入其他导流腔310中而只能进入与气路通道180连通的第二排气腔体190中，进而可通过第二排气通道191排出，第一气囊801中的气压降低。当压力传感器741监控到第一气囊801中的气压值降低至所需的气压值Pc1时，第二排气电磁阀192断电关闭，第一气囊801中的气体停止排气释压。通过上述步骤，即可单独对第一气囊801中气压值进行调节。
同理，如图30和图31所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，气源700停止充气。第二气腔电磁阀502和第二排气电磁阀192通电打开，第一气腔电磁阀501、第三气腔电磁阀503、第四气腔电磁阀504和第五气腔电磁阀505保持断电关闭状态。第二气囊802中的气体进入第二排气腔体190中，进而通过第二排气通道191排出，第二气囊802中的气压降低。当压力传感器741监控到第二气囊802中的气压值降低至所需的气压值Pc2时，第二排气电磁阀192断电关闭，第二气囊802中的气体停止排气释压。通过上述步骤，即可单独对第二气囊802中气压值进行调节。
同理，如图32和图33所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，气源700停止充气。第三气腔电磁阀503和第二排气电磁阀192通电打开， 第一气腔电磁阀501、第二气腔电磁阀502、第四气腔电磁阀504和第五气腔电磁阀505保持断电关闭状态。第三气囊803中的气体进入第二排气腔体190中，进而通过第二排气通道191排出，第三气囊803中的气压降低。当压力传感器741监控到第三气囊803中的气压值降低至所需的气压值Pc3时，第二排气电磁阀192断电关闭，第三气囊803中的气体停止排气释压。通过上述步骤，即可单独对第三气囊803中气压值进行调节。
同理，如图34和图35所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，气源700停止充气。第四气腔电磁阀504和第二排气电磁阀192通电打开，第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503和第五气腔电磁阀505保持断电关闭状态。第四气囊804中的气体进入第二排气腔体190中，进而通过第二排气通道191排出，第四气囊804中的气压降低。当压力传感器741监控到第四气囊804中的气压值降低至所需的气压值Pc4时，第二排气电磁阀192断电关闭，第四气囊804中的气体停止排气释压。通过上述步骤，即可单独对第四气囊804中气压值进行调节。
同理，如图36和图37所示，第一排气电磁阀230通电保持开启状态以使气压调整装置维持保压状态，气源700停止充气。第五气腔电磁阀505和第二排气电磁阀192通电打开，第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503和第四气腔电磁阀504保持断电关闭状态。第五气囊805中的气体进入第二排气腔体190中，进而通过第二排气通道191排出，第五气囊805中的气压降低。当压力传感器741监控到第五气囊805中的气压值降低至所需的气压值Pc5时，第二排气电磁阀192断电关闭，第五气囊805中的气体停止排气释压。通过上述步骤，即可单独对第五气囊805中气压值进行调节。
另外，可通过对所有气囊800进行排气释压以使所有气囊800中的气压值相同，即Pb1＝Pb2＝Pb3＝Pb4＝Pb5，即可实现均压效果。
4)断电自动泄压
如图38和图39所示，所有电磁阀，包括第一气腔电磁阀501、第二气腔电磁阀502、第三气腔电磁阀503、第四气腔电磁阀504、第五气腔电磁阀505、第一排气电磁阀230和第二排气电磁阀192全部断电，并且气源700也断电停止充气。此时，保压通道200与第一排气腔体631连通，保压通道200不再封闭，保压通道200中的气体通过第一排气通道230排出，则保压通道200中的气压降低，当保压通道200中的气压值降低至小于各三通腔体300中的气压值时，各单向阀320被冲开，各气囊800中的气体穿过对应的单向阀320进入排气通道200中，最后通过第一排气通道230排出，从而实现了对所有气囊800的泄压。通过气压按摩仪的断电自动泄压功能，在气压按摩仪遇到故障断电后，所有气囊800放气泄压从而确保了气囊800不会一直挤压用户肢体，有效提高了用户使用气压按摩仪时的安全性。
进一步的，上述四种动作可通过不同的控制逻辑来进行组合，例如保压按摩和均压及调压合能够实现多种按摩模式，达到可均压、单腔气压可调且功耗低的效果；预充保压和保压按摩组合能够起到保压的效果；通过对上述四种动作的结合使用能够有效提高气压按摩仪的产品使用体验，使得气压按摩仪的应用场合更加广泛，适用人群更多。
