一種乳液泵結構的制作方法

本實用新型涉及一種乳液泵結構。



背景技術:

乳液泵由于其設計精美,使用方便,已廣泛地應用與日化和醫藥等行業。但是現有的乳液泵零件多,結構復雜,制作難度大,生產成本高;而且現有的乳液泵的彎嘴沒有防滑功能,在產品運輸過程中受到的碰撞容易導致彎嘴轉動而誤打開,導致瓶內液體的泄露;現有乳液泵彎嘴打開后,水、空氣等雜質會從泵體的縫隙進入大泵室,進而污染乳液,不衛生,不環保。

本實用新型正是基于以上的不足而產生的。



技術實現要素:

本實用新型要解決的技術問題是提供一種結構簡單,成本低的乳液泵結構。

為解決上述技術問題,本實用新型采用了下述技術方案:一種乳液泵結構,其特征在于,包括伸入瓶體內的泵體1,所述的泵體1上設置有泵室2,所述泵體1上連接有能將其固定到瓶體上的鎖瓶蓋3,所述的泵室2內設置有能在其內上下移動而將瓶體內的液體向上抽出的抽吸組件4,所述泵室2的下端設置有在抽吸組件4運動時僅供瓶體內的液體向上排出的第一單向閥5,所述抽吸組件4上端連接有彎嘴6,所述鎖瓶蓋3的上端一體成型有能與彎嘴6轉動連接的鎖緊部7;所述的鎖緊部7與彎嘴6之間設置有在二者連接時能防止彎嘴6轉動而打開的防滑裝置。

如上所述的一種乳液泵結構,其特征在于,所述的抽吸組件4包括有與彎嘴6連接并具有抽吸通道42的泵桿41,泵桿41上設置有能連通抽吸通道42與泵室2的進氣孔411,所述抽吸通道42內并位于進氣孔411的上方設置有第二單向閥9,所述泵桿41上一體成型有活塞43,所述的泵室2下端設置有限位臺階21,所述的活塞43與限位臺階21之間設置有復位彈簧44。

如上所述的一種乳液泵結構,其特征在于,所述的防滑裝置包括有設置在鎖緊部7外壁上的防滑齒81,所述彎嘴6的內壁上設有能與防滑齒81抵靠進而阻止彎嘴6轉動的彈性彎曲片61。

如上所述的一種乳液泵結構,其特征在于,所述的泵室2下端呈錐形,所述的第一單向閥5為設置在泵室2下端的第一泵珠。

如上所述的一種乳液泵結構,其特征在于,所述的第二單向閥9為設置在抽吸通道42內的第二泵珠。

如上所述的一種乳液泵結構,其特征在于,所述泵桿41的下端設置有在其未上升時能將第一泵珠抵壓在泵室2下端的外凸部412。

如上所述的一種乳液泵結構,其特征在于,所述的泵體1并位于第一單向閥5的下方還設置有引液管10。

與現有技術相比,本實用新型的一種乳液泵結構,達到了如下效果:

1、本實用新型的鎖瓶蓋與鎖緊部為一體成型的整體結構,減少了配件,降低了模具的開發成本,提高組裝效率以及降低因配件裝配問題所帶來的泄露風險,提高產品的質量。

2、本實用新型的防滑裝置包括有設置在鎖緊部外壁上的防滑齒,彎嘴的內壁上設有能與防滑齒抵靠進而阻止彎嘴轉動的彈性彎曲片,在彎嘴與鎖緊部順時針轉動連接時,防滑齒與彈性彎曲片接觸并擠壓彎曲片使彎曲片變形,當彎嘴轉動到所需位置時,彎曲片彈性恢復,彎曲片的端部就抵靠在防滑齒上,此時,裝有乳液的瓶體在運輸過程中即使受到震動,防滑齒頂住彎曲片而阻止彎嘴逆時針轉動,這樣就避免彎嘴誤打開而造成泄露。

【附圖說明】

下面結合附圖對本實用新型的具體實施方式作進一步詳細說明,其中:

圖1為本實用新型在彎嘴與鎖緊部連接時的立體圖;

圖2為本實用新型在彎嘴與鎖緊部未連接時的立體圖;

圖3為本實用新型在彎嘴被壓下去時的剖視圖;

圖4為本實用新型在彎嘴與鎖緊部未連接時的剖視圖;

圖5為本實用新型在彎嘴與鎖緊部連接時的剖視圖。

【具體實施方式】

下面將結合本實用新型實施例中的附圖,對本實用新型實施例中的技術方案進行清楚、完整地描述。

如圖1至圖5所示,一種乳液泵結構,包括伸入瓶體內的泵體1,所述的泵體1上設置有泵室2,所述泵體1上連接有能將其固定到瓶體上的鎖瓶蓋3,所述的泵室2內設置有能在其內上下移動而將瓶體內的液體向上抽出的抽吸組件4,所述泵室2的下端設置有在抽吸組件4運動時僅供瓶體內的液體向上排出的單向閥5,所述抽吸組件4上端連接有彎嘴6,所述鎖瓶蓋3的上端一體成型有能與彎嘴6轉動連接的鎖緊部7;所述的鎖緊部7與彎嘴6之間設置有在二者連接時能防止彎嘴6轉動而打開的防滑裝置。鎖瓶蓋與鎖緊部為一體成型的整體結構,減少了配件,降低了模具的開發成本,提高組裝效率以及降低因配件裝配問題所帶來的泄露風險,提高產品的質量;而且的鎖緊部與彎嘴之間設置有在二者連接時能防止彎嘴轉動而打開的防滑裝置,所以在彎嘴與鎖緊部旋緊后,即使在震動時,防滑裝置也能阻止彎嘴與鎖緊部之間的轉動,從而避免彎嘴轉動而誤打開,防止產品的泄露。

如圖1至圖5所示,在本實施例中,所述的抽吸組件4包括有與彎嘴6連接并具有抽吸通道42的泵桿41,泵桿41上設置有能連通抽吸通道42與泵室2的進氣孔411,所述抽吸通道42內并位于進氣孔411的上方設置有第二單向閥9,所述泵桿41上一體成型有活塞43,所述的泵室2下端設置有限位臺階21,所述的活塞43與限位臺階21之間設置有復位彈簧44。本實用新型的活塞與泵桿為一體成型的整體結構,減少了配件,降低了模具的開發成本,避免了在使用過程中活塞從泵桿上脫落,提高了結構的穩定性。

如圖1至圖5所示,在本實施例中,所述的防滑裝置包括有設置在鎖緊部7外壁上的防滑齒81,所述彎嘴6的內壁上設有能與防滑齒81抵靠進而阻止彎嘴6轉動的彈性彎曲片61。在彎嘴與鎖緊部順時針轉動連接時,防滑齒與彈性彎曲片接觸并擠壓彎曲片使彎曲片變形,當彎嘴轉動到所需位置時,彎曲片彈性恢復,彎曲片的端部就抵靠在防滑齒上,此時,裝有乳液的瓶體在運輸過程中即使受到震動,防滑齒頂住彎曲片而阻止彎嘴逆時針轉動,這樣就避免彎嘴誤打開而造成泄露。

在本實施例中,防滑齒為6個,并圓周陣列于鎖緊部上,彎曲片為兩組,兩組彎曲片圓周陣列于彎嘴上,并且每組彎曲片為兩片,因此,在旋緊彎嘴時,可以適當調整松緊程度,在彎嘴順時針或逆時針出現角度偏移時,仍然具有能夠頂靠防滑齒的彎曲片,提高產品的可靠性。

如圖1至圖5所示,在本實施例中,所述的泵室2下端呈錐形,所述的單向閥5為設置在泵室2下端的第一泵珠。

如圖1至圖5所示,在本實施例中,所述的第二單向閥9為設置在抽吸通道42內的第二泵珠。抽吸通道內設置有錐形臺階,第二泵珠位于錐形臺階上。

如圖1至圖5所示,在本實施例中,所述泵桿41的下端設置有在其未上升時能將第一泵珠抵壓在泵室2下端的外凸部412。防止在運輸過程中液體泄露。

如圖1至圖5所示,在本實施例中,所述的泵體1并位于單向閥5的下方還設置有引液管10。

使用時,先將彎嘴6旋轉與鎖緊部7分離,抽吸組件4在彈簧的彈性力作用下向上運動,此時,第一次向下按壓彎嘴6,抽吸組件跟隨彎嘴向下運動,活塞43將泵室2內的氣體從進氣孔411壓入到抽吸通道42內,然后氣體從第二單向閥9排出,此時泵室2處于負壓狀態,松開手后,抽吸組件4在彈簧44的彈性力下向上運動,由于泵室2內的壓力小于瓶體內的壓力,此時,第一單向閥5打開,瓶內的乳液進入到泵室2內,當泵室內的氣壓與瓶內的氣壓相等時,第一單向閥5關閉,再次按壓彎嘴6,活塞43向下運動擠壓泵室2,此時,乳液從進氣孔411進入到抽吸通道42內,然后從第二單向閥9排出,進而從彎嘴流出。
