 本发明的实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
本发明提供了一种防污染瓶盖，其第一个实施例如图1和图3所示，包括盖体10、出液单向阀20和进气单向阀30；盖体10上设有出液孔11和进气孔12，出液孔11和进气孔12均与盖体10的内部导通；出液单向阀20设于盖体10围纳的空间内，出液单向阀20单向封堵出液孔11，以使出液孔11在进行倾倒操作时导通；进气单向阀30设于盖体10围纳的空间内，进气单向阀30单向封堵进气孔12，以使进气孔12在进行倾倒操作时封闭。
在进行应用时，防污染瓶盖会安装在瓶子40上配合使用，对瓶子40倾倒后，使用者只需挤压瓶子40，出液单向阀20将解除对出液孔11的封堵，进气单向阀30将封堵进气孔12，液体便可正常经出液孔11排出，而在停止使用时，进气单向阀30解除对进气孔12的封堵，恢复瓶内的气压，出液单向阀20对出液孔11的封堵，则防止了使用者体表的粘附物进入瓶内，不会对内容物造成污染，切实解决了现有瓶盖容易污染内容物的问题。
如图1和图2所示，盖体10内部设有出液腔13和进气腔14，出液腔13与出液孔11导通，进气腔14与进气孔12导通；防污染瓶盖还包括支架50，支架50包括出液架体51和进气架体52；出液架体51嵌入并围蔽封堵出液腔13内，出液架体51设有导液孔511，导液孔511与出液腔13导通，出液单向阀20单向封闭导液孔511；进气架体52嵌入并围蔽封堵进气腔14内，进气架体52设有导气孔521，导气孔521与进气腔14导通，进气单向阀30向封闭导气孔521。
在图1和图2所示方向中，出液腔13和进气腔14左右并排布置，出液腔13和进气腔14均围纳为圆柱管状结构，而出液架体51和进气架体52则类似圆柱结构，两者分别匹配插入出液腔13和进气腔14，以此实现对出液腔13和进气腔14的围蔽，也便于出液单向阀20和进气单向阀30的安装。
如图1、图2和图4所示，出液单向阀20包括出液堵芯21和软胶挡片22；出液堵芯21的一端与盖体10内顶壁抵接，出液堵芯21的另一端穿入导液孔511内，出液堵芯21的直径小于导液孔511的孔径；软胶挡片22设于出液腔13内，软胶挡片22围绕出液堵芯21周向设置一圈，软胶挡片22延伸至导液孔511的周向外，以使软胶挡片22阻隔导液孔511和出液孔11的导通，且软胶挡片22的受压弯折用于导通导液孔511和出液孔11。
当盖体10正置时，软胶挡片22处于伸展状态，所以软胶挡片22将完全遮盖导液孔511，从而实现了导液孔511与出液孔11的阻隔，以防止污染物经出液孔11进入至瓶内；而在需要出液使用时，盖体10将会处于翻转状态，若对瓶子40进行挤压，液体将会对软胶挡片22施加向下的推力，从而使得软胶挡片22向下弯折形成空隙，液体便可流向出液孔11实现出液。
如图1和图2所示，导液孔511的内壁设有内台阶512，内台阶512围绕导液孔511的内壁周向布置一圈，以使导液孔511的孔径在往远离出液孔11的方向上呈缩小变化。
在采用此结构后，将使得在邻近软胶挡片22的位置上，出液堵芯21与导液孔511之间的空间更大，不但能够增大液体流量，也确保软胶挡片22在较少形变幅度下也能实现液体的畅通流动。
如图1、图2和图5所示，进气单向阀30包括相互连接的导柱31和密封罩32；导柱31的直径小于导气孔521的孔径，导柱31穿过导气孔521，导柱31置于进气腔14内的部位设有挡块33，挡块33往导气孔521的周向外延伸，挡块33用于与进气架体52抵接以阻止进气单向阀30脱离；密封罩32置于进气腔14外，密封罩32与进气架体52相互分离，且密封罩32能够在倾倒操作下受力形变，以封闭导气孔521。
此实施例的密封罩32大致呈蘑菇状，在盖体10正置的时候，密封罩32处于未受力的状态，密封罩32与进气架体52相互分离，从而确保瓶体内外的气压平衡；而在需要倾倒出液时，液体将会密封罩32施加压力，密封罩32扩展形变以与进气架体52抵接，从而实现了对导气孔521的封闭，避免了液体从导气孔521流至进气孔12。
如图2所示，导气孔521的孔径在往远离进气孔12的方向上呈线形增大变化。
以图示方向为例，在采用此结构后，侧可便于挡块33从下往上推动，直至挡块33穿过导气孔521，以实现进气单向阀30与进气架体52的扣合式安装。
如图2、图4和图5所示，导气孔521为十字形，导柱31相对的两侧均设有挡块33。
所以在进行进气单向阀30的安装时，两个挡块33会穿过导气孔521十字形的相对两端，导气孔521十字形的另外两端将处于未被遮挡的状态，从而确保了导气孔521两侧的气流导通，避免出现导气孔521被堵塞的现象。
如图1和图3所示，盖体10连接有可打开和翻合的翻盖60，翻盖60的翻合用于包围封闭出液孔11和进气孔12。
在增设翻盖60后，则可在无需使用时翻合翻盖60，以此对出液孔11和进气孔12实现保护。
本发明防污染瓶盖的第二个实施例如图7和图8所示，其与防污染瓶盖的第一个实施例基本一致，区别在于，盖体10内部设有出液腔13，出液腔13与出液孔11导通；防污染瓶盖还包括出液架体51，出液架体51嵌入并围蔽封堵出液腔13内，出液架体51设有导液孔511，导液孔511与出液腔13导通；出液单向阀20包括出液堵芯21和软胶挡片22；出液堵芯21的一端与盖体10内顶壁抵接，出液堵芯21的另一端穿入导液孔511内，出液堵芯21的直径小于导液孔511的孔径；软胶挡片22设于出液腔13内，软胶挡片22围绕出液堵芯21周向设置一圈，软胶挡片22延伸至导液孔511的周向外，以使软胶挡片22阻隔导液孔511和出液孔11的导通，且软胶挡片22的受压弯折用于导通导液孔511和出液孔11；且盖体10内部设有进气腔14，进气腔14与进气孔12导通；防污染瓶盖还包括进气架体52，进气架体52嵌入并围蔽封堵进气腔14内，进气架体52设有导气孔521，导气孔521与进气腔14导通；进气单向阀30包括相互连接的导柱31和密封罩32；导柱31的直径小于导气孔521的孔径，导柱31穿过导气孔521，导柱31置于进气腔14内的部位设有挡块33，挡块33往导气孔521的周向外延伸，挡块33用于与进气架体52抵接以阻止进气单向阀30脱离；密封罩32置于进气腔14外，密封罩32与进气架体52相互分离，且密封罩32能够在倾倒操作下受力形变，以封闭导气孔521。
即此实施例将出液架体51和进气架体52分为两个独立的部件，不再将两者连接为一个整体，同样能够实现相同的功能，由于此实施例实现的功能与第一个实施例基本一致，故此不再叙述。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
