Description

弹簧上置式乳液泵
技术领域
本实用新型涉及一种乳液泵,尤其涉及一种弹簧上置式乳液泵。
背景技术
乳液泵一般包括按头、泵壳、主泵芯、副泵芯、弹簧、波珠、牙盖、锁盖。按头、主泵芯和副泵芯依次连接在一起,并在主泵芯和副泵芯之间套有活塞;在泵体中从下而上依次设有波珠、弹簧、套有活塞的副泵芯、主泵芯和按头。在泵壳上套有牙盖,在主泵芯上套有锁盖。锁盖连接泵体,牙盖把泵体与瓶体连接起来。此种乳液泵,在泵壳中吸入乳液后,泵壳中的弹簧与乳液接触,由于弹簧是金属的,长久与乳液接触后会与乳液发生反应,或者金属物质混合在乳液当中,对乳液造成污染,既不卫生又不安全。且弹簧限制了泵芯和活塞向下移动的行程,使活塞不能伸入到泵壳的底部,使吸入泵壳中的乳液不能充分压出使用。
发明内容
针对上述缺点,本实用新型的目的是提供一种弹簧与乳液隔离的弹簧上置式乳液泵。
为实现上述目的,本实用新型的技术内容为,一种弹簧上置式乳液泵,包括按头、泵壳,主泵芯、副泵芯、活塞、弹簧、下波珠、及牙盖,还包括由内管和外管组成的连杆、颈环和上波珠;牙盖套在泵壳上,颈环连接在泵壳中;连杆的外管套在内管外,并连接在内管的外壁上;弹簧设置在连杆的内管与外管之间,按头与连杆连接,连杆设置在颈环中,将内管穿过颈环底部进入泵壳,弹簧限位在颈环的底部;主泵芯的上端与连杆的内管连接,下端与副泵芯连接,在主泵芯上还设有活塞,副泵芯设有侧孔;下波珠设在泵壳内的底部进液口中,内管中的上端设有带孔凹槽,上波珠设在带孔凹槽中;按头的底部对准连杆的内管的带孔凹槽的位置设有把上波珠限制在带孔凹槽中的顶针;颈环上连接颈环套,在外管下端的外壁上设有防止外管跑出颈环的外管凸环。
进一步的是:在泵壳上设有环形卡板,牙盖套在泵壳上,限位在环形卡板处。
进一步的是:泵壳设有连接口,连接口外壁有凸环;颈环上端外壁设有颈环盖,颈环盖的内侧壁上有环形凹槽;连接口的凸环卡入颈环盖的环形凹槽使颈环与泵壳连接。
与现有技术相比,本实用新型中的弹簧设置在颈环处的连杆的内管外与泵体内的乳液是完全隔离的,对乳液不会造成污染,使乳液更卫生更安全。而且现有技术中的弹簧置于泵体中,泵芯推动弹簧收缩,由于弹簧自身收缩后的长度限制了泵芯上的活塞继续推动乳液,使进入泵体的乳液不能充分地被压出,影响乳液一次挤压出来的量。本实用新型在泵体中去掉了弹簧,活塞可以移动到接近泵体底部,加大了活塞活动行程,使乳液能充分压出。另外在连杆的内管外设置外管,可以避免弹簧暴露在外面,使外观更美观,也可保护弹簧在伸缩过程中避免与颈环套内侧刮擦损伤。综上所述,本实用新型所具有的优点是使乳液更卫生安全,泵体更美观,一次挤压出的量更足。
附图说明
图1是本实用新型在压液状态下的结构示意图。
图2是本实用新型在吸液状态下的结构示意图。
具体实施例
下面结合附图对本实用新型作进一步详细描述。
如图1图2所示,一种弹簧上置式乳液泵,包括按头1、泵壳2,主泵芯3、副泵芯4、活塞10、弹簧5、下波珠6、及牙盖7,还包括由内管8.1和外管8.2组成的连杆8、颈环9和上波珠12。
在泵壳上设有环形卡板2.2,牙盖7套在泵壳2上,限位在环形卡板2.2处。泵壳2设有连接口2.3,连接口2.3外壁有凸环;颈环9上端外壁设有颈环盖9.1,颈环盖9.1的内侧壁上有环形凹槽;连接口2.3的凸环卡入颈环盖9.1的环形凹槽使颈环9与泵壳2连接。
连杆8的外管8.2套在内管8.1外,并连接在内管8.1的外壁上;弹簧5设置在连杆8的内管8.1与外管8.2之间,按头1与连杆8连接,连杆8设置在颈环9中,将内管8.1穿过颈环9底部进入泵壳2,弹簧5限位在颈环9的底部;主泵芯3的上端与连杆8的内管8.1连接,下端与副泵芯4连接,在主泵芯3上还设有活塞10,副泵芯4设有侧孔11;下波珠6设在泵壳2内的底部进液口2.1中,内管8.1中上端设有带孔凹槽8.3,上波珠12设置在带孔凹槽8.3中;按头1的底部对准连杆8的内管8.1的带孔凹槽8.3的位置设有把上波珠12限制在带孔凹槽8.3中的顶针1.1;颈环9上连接颈环套13,在外管8.2下端的外壁上设有防止外管8.2跑出颈环9的外管凸环8.4。
压液过程如下:按下按头1,推动连杆8、主泵芯3和副泵芯4向下移动,活塞10推动乳液,使下波珠6堵住进液口2.1,推开上波珠(12)打通内管8.1,乳液在活塞10的推动下从副泵芯4的侧孔进入,流经副泵芯4、主泵芯3进入连杆8的内管8.1直到进入按头1,最后从按头1出液口出来。
吸液过程如下:松开按头1,在弹簧5的反弹作用下,按头带动连杆8、主泵芯3和副泵芯4收回,活塞10后移泵内产生负压使上波珠12堵住内管8.1,下波珠6离开进液口,从而液体从吸液口吸入泵体内。
