Description

一种新型喷头 技术领域
本发明涉及一种新型喷头。
背景技术
在化妆品领域，经常使用具有喷头的瓶体储存液体，例如乳液泵。乳液泵广泛用于化妆品及沐浴用品，当需要使用时，按压按头，即可把需要的乳液取出，这种方法即方便又卫生。授权公告号为CN203127397U的中国实用新型专利《一种新型乳液泵》(申请号：201320109153.0)披露了一种结构，其包括按头，接头套设于螺牙上端，按头底部与螺牙内部相对应设置有卡位，按头底部与螺牙上端设置的扣线相配合，螺牙内部设置有主柱，主柱顶端与按头内部相互倒角配合设置，主柱下方还设置有副柱，主柱和副柱之间设有弹簧，在螺牙下端套设有吸管。上述结构的乳液泵采用按头底部与螺牙内部卡位连接，按下按头旋转90度可切换开关，按头内部与主柱顶端相互倒角配合，按头上下活动时可产生吸力和泵液效果。
现有技术中的泵体普遍与上述结构类似，即空气通道及液体通道分为两路，这样的结构在使用时，需要先按压几次按头，将泵体中的空气排空，再在瓶体内储存一定的压力，才能将液体排出，且由于空气通道及液体通道分为两路，容易存在一定量的压力损失，导致出液速度慢，并且，无法适用于粉末的存储及输出。
发明内容
本发明所要解决的技术问题是针对现有技术的现状，提供一种即能适用于液体又能适用于粉末且出料速度快的新型喷头。
本发明解决上述技术问题所采用的技术方案为：一种新型喷头，其特征在于：包括
瓶体，该瓶体内部中空从而形成用以储存物料的容置腔，所述瓶体顶部具有与容置腔相连通的开口；
泵体，该泵体上部限位在所述瓶体开口上，该泵体下部位于瓶体的容置腔中；所述泵体中部设置有上下贯通的第一导流通道；
活塞，能上下移动地设于泵体上部，该活塞上开设有与第一导流通道相连通的第二导流通道；
泵套，设于所述泵体上部并将活塞约束在泵体上；
弹簧，设于所述泵体中并上端与活塞相抵从而使所述活塞始终保持向上移动的趋 势；

头帽，能上下移动地设于泵套上并内顶面与活塞的上端相抵，所述头帽的一侧开有与第二导流通道相连通的喷口。
作为改进，所述的管吸装置还包括有堵塞，所述堵塞设于泵体下方，所述堵塞的顶部具有向上延伸并穿过泵体底部伸入泵体中的配合柱，所述活塞向下移动状态下能抵压配合柱并驱使堵塞向下移动。采用上述结构，以实现吸管下移，从而将瓶体中的物料压入吸管并进一步输出。
为了便于生产及装配，所述堵塞能上下移动地套置在第一导流通道外周，所述吸管上部能上下移动地套置在第一导流通道外周并上端面与堵塞的下表面相抵。所述堵塞的下表面上设置有向下延伸的装配套，该装配套的内表面与第一导流通道的外壁面共同形成能与吸管导向配合的导向槽。
在上述方案中，所述第一导流通道设于泵体中部，所述泵体上设置有围绕第一导流通道外周布置的环形套，该环形套与第一导流通道之间连接有衔接片，该衔接片与所述第一导流通道的外壁、环形套的内壁共同围合成供活塞上下移动的配合腔。
为了便于装配，所述活塞的内壁面上设置沿高度方向延伸的定位筋，对应的，所述泵体的配合腔中竖向布置有能与定位筋上下导向配合而限制活塞相对于泵体周向转动的限位件。该限位件包括间隔布置的第一限位柱、第二限位柱，活塞上的定位筋插置在第一限位柱与第二限位柱之间的间隙中。
作为改进，所述的新型喷头还包括能对物料流量进行限制的限流杆，该限流杆可以采用不同的结构型式，其一；它可活动插置在第一导流通道中，该限流杆的外周面与第一导流通道的内周壁之间形成有供物料及气体通过的间隙。所述限流杆的上端露出于第一导流通道的上端并具有能防止限流杆整体落入第一导流通道中的限位部。该限位部与导流杆主体的衔接处平滑过渡。采用该结构，一方面可防止出料量过猛，造成浪费；另一方面，可避免气体过快进入瓶体，影响出料量。其二：该限流杆上端可与头帽相连接，限流杆的下部成形有能将内容物向上提起的提取结构，限流杆的上部的外周面上凸设有能将内容物向上引导并增大内容物喷出状态下的分散度的导流结构；所述提取结构为沿限流杆周向布置的凸块，该凸块为多个并沿限流杆上下间隔布置，所述导流结构为沿限流杆长度方向延伸的螺旋筋。
为了便于装配，所述泵体上部设置有能套置在瓶体开口外周的装配圈，所述泵套套置在装配圈的外周并顶部具有能与活塞下部相抵的限位圈。所述限位圈与活塞上部的外周壁之间构成一导向通道，所述头帽的下部具有能上下移动地插置在该导向通道中的导向套。
优选地，本实施例中的弹性结构为螺旋设于吸管下端的弹性筋，该弹性筋的下端连接有一坐落在瓶体底部的支撑环。采用该结构，以使吸管保持向上移动的趋势，在出料完毕后吸管自动复位。
优选地，所述头帽本体顶部的中央位置设置有能与喷嘴及活塞保持静止的第一顶盖，所述头帽本体顶部的外围设置有能随头帽本体转动的第二顶盖，该第二顶盖与第一顶盖上对应设置有能对出料状态与否进行指示的指示结构。
与现有技术相比，本发明的优点在于：本发明通过泵体、管吸装置、活塞、弹簧、泵套及头帽的相互配合，使得本发明喷头的出料通道及气体通道为同路通道，使用时，下压头帽，头帽带动活塞一起向下运动使弹簧压缩，待活塞下行顶住管吸装置的堵塞上端时，驱使吸管一起向下运动，吸管底部的弹性结构向下压缩变形，在此过程中，瓶体内的液体受压力并通过吸管经过泵体流动至头帽的喷口喷出；松开头帽后，受弹簧弹力的作用，头帽和活塞一起向上运动，直至活塞顶住泵套，由于活塞向上复位，管吸装置不再受到活塞向下力的作用，受吸管下端弹性结构的变形力作用，吸管向上运动复位，在此过程中，受大气压的作用，外界的空气通过原先液体的出液路径填充如瓶体内；上述过程中，出料通道及气体通道为同路通道，无需在瓶体内储压，按压头帽可迅速将物料输出，且由于整个过程不易存在气压损失，使得本发明的喷头既能适用于液体又能适用于粉末。

具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
实施例一、如图1～6所示，本实施例的新型喷头包括瓶体3、泵体1、管吸装置4、活塞6、弹簧7、泵套8及头帽2。
其中，瓶体3内部中空从而形成用以储存物料的容置腔31，瓶体3顶部具有与容置腔31相连通的开口32。泵体1上部限位在瓶体3的开口32上，泵体1下部位于瓶体3的容置腔31中，泵体1中部设置有上下贯通的第一导流通道10。具体的，第一导流通道10设于泵体1中部，泵体1上设置有围绕第一导流通道10外周布置的环形套12，该环形套12与第一导流通道10之间连接有衔接片13，该衔接片13与第一导流通道10的外壁、环形套13的内壁共同围合成供活塞6上下移动的配合腔14。
本实施例的活塞6能上下移动地设于泵体1上部的配合腔14中，活塞6上开设有与第一导流通道10相连通的第二导流通道61。管吸装置4与泵体1相连接，管吸装置4通过活塞6的上下移动而使管吸装置4上下动作，它包括有与第一导流通道10贯通的吸管42及使管吸装置4始终保持向上移动趋势的弹性结构41。管吸装置4除吸管42外还包括有堵塞5，堵塞5设于泵体1下方，堵塞5的顶部具有向上延伸并穿过泵体1底部伸入泵体的配合腔14中的配合柱51，活塞6向下移动状态下能抵压配合柱51并驱使堵塞5向下移动。弹簧7套置于第一导流通道10及第二导流通道61的外周，弹簧7设于泵体1中并上端与活塞6相抵从而使活塞6始终保持向上移动的趋势。泵套8设于泵体1上部并将活塞6约束在泵体1上。头帽2能上下移动地设于泵套8上并内顶面与活塞6的上端相抵，头帽2的一侧开有与第二导流通道61相连通的喷口29。
弹簧7的下端与衔接片13的上表面相抵，弹簧7的上端与活塞6的第二导流通道61的顶部的壁面相抵。具体的，堵塞5能上下移动地套置在第一导流通道10的外周，吸管4上部能上下移动地套置在第一导流通道10外周并上端面与堵塞5的下表面相抵。堵塞5的下表面上设置有向下延伸的装配套52，该装配套52的内表面与第一导流通道10的外壁面共同形成能与吸管4导向配合的导向槽53。采用上述结构，以实现吸管4下移，从而将瓶体3中的物料压入吸管4并进一步输出。为了便于装配，活塞6的内壁面上设置沿高度方向延伸的定位筋62，对应的，泵体1的配合腔14中竖向布置有能与定位筋62上下导向配合而限制活塞6相对于泵体1周向转动的限位件。该限位件包括间隔布置的第一限位柱15、第二限位柱16，活塞6上的定位筋62插置在第一限位柱15与第二限位柱16之间的间隙中。
本实施例的第一导流通道10中活动插置有能对物料流量进行限制的限流杆9a，该限流杆9a的外周面与第一导流通道10的内周壁之间形成有供物料及气体通过的间隙91a。限流杆9a的上端露出于第一导流通道10的上端并具有能防止限流杆9a整体落入第一导流通道10中的限位部92a。该限位部92a与导流杆9a主体的衔接处平滑过渡。 采用该结构，一方面可防止出料量过猛，造成浪费；另一方面，可避免气体过快进入瓶体，影响出料量。
在本实施例中，泵体1上部设置有能套置在瓶体3开口31外周的装配圈17，泵套8套置在装配圈17的外周并顶部具有能与活塞6下部相抵的限位圈81。限位圈81与活塞6上部的外周壁之间构成一导向通道82，头帽2的下部具有能上下移动地插置在该导向通道82中的导向套20。本实施例中的弹性结构41包括弹性筋411及支撑环412，支撑环412坐落在瓶体1的底部，弹性筋411为3条并间隔螺旋布置于吸管4下端与支撑环412之间。采用该结构，以使吸管4保持向上移动的趋势，在出料完毕后吸管自动复位。
本实施例的头帽2为一组件结构，其包括头帽本体21及喷嘴22，头帽本体21能转动地设于活塞6上，活塞6顶部设置有用于容纳喷嘴22的安装腔61，该安装腔61的侧壁上开有与喷嘴22的喷口29相对应的通孔611，头帽本体21的侧部开设有与该通孔611相连通的导料通道。具体的，导料通道包括分别布置于头帽本体21两侧的第一导料通道212及第二导料通道213，第一导料通道212的内径小于第二导料通道213的内径。本实施中第一导料通道212的内径内外相等，第二导料通道213的内径成形为自内而外逐渐增大的喇叭状。设置两个通道，使用者可根据需要的出液量大小来选择相应通道，从而更好的满足消费者的需求。
本实施例中头帽本体21顶部的中央位置设置有能与喷嘴22及活塞6保持静止的第一顶盖23，头帽本体21顶部的外围设置有能随头帽本体21转动的第二顶盖24，该第二顶盖24与第一顶盖23上对应设置有能对出料状态与否进行指示的指示结构25。头帽本体21的中部具有与活塞6上部相插配连接的装配槽214，该装配槽214的顶壁面上开设有对应喷嘴21布置的装配孔215，喷嘴22顶壁面上设置有向装配孔215中延伸的装配圈222，第一顶盖23的下表面与该装配圈222相连接。装配圈222为梯形或三角形状，第一顶盖23的下表面上设置有能该装配圈222配合卡接的卡扣231。第一顶盖23的下表面设置有能与装配圈222的内沿相贴近布置的装配筋232，卡扣231为至少两个并分别设于装配筋232的不同边上。头帽本体21的顶部设置有环形布置的插槽216，第二顶盖24的下表面上设置有能插置在该插槽216中的插接套241。喷嘴22具有能插置在活塞6出料口63中的进液通道223。当使用本实施例的喷头时，旋转头帽本体21，使头帽本体21上的导料通道212/213与活塞6上的喷嘴22喷口29相对应，可实现内容物的输出；使用完毕后，旋转头帽本体21，使头帽本体21上的导料通道212/213与活塞6上的喷嘴22喷口29相错开，可对喷嘴22喷口29进行封闭，避免活塞6内滞留的内容物被氧化。
使用本实施例的喷头时，下压头帽2，头帽2带动活塞6一起向下运动(如图7)，使弹簧7压缩，待活塞6下行顶住堵塞5上端时(如图8)，堵塞5和活塞6一起向下运 动(如图9)，此时，堵塞5驱使吸管4一起向下运动，吸管4底部的弹性结构41向下压缩变形，在此过程中，瓶体3内的液体受压力并通过吸管4经过泵体1流动至头帽2的喷口29喷出；松开头帽2后，受弹簧7弹力的作用，头帽2和活塞6一起向上运动(如图10)，直至活塞6顶住泵套8，由于活塞6向上复位，堵塞5不再受到活塞6向下力的作用，受吸管4下端弹性结构41的变形力作用，吸管4和堵塞5一起向上运动(如图11)，直至堵塞抵住泵体1(如图12)，在此过程中，受大气压的作用，外界的空气通过原先液体的出液路径填充入瓶体3内。
实施例二、如图13、14所示，它与实施例一的主要区别是采用了不同结构的限流杆，本实施例中的限流杆9b包括杆体91b，该杆体91b下部成形有能将内容物向上提起的提取结构93b，杆体91b上部的外周面上凸设有能将内容物向上引导并增大内容物喷出状态下的分散度的导流结构92b。
其中，提取结构93b为沿杆体91b周向布置的凸块931，该凸块931为多个并沿杆体91b上下间隔布置。当限流杆随本实施例的喷头的头帽2上下移动时，凸块931可防止已经被挤压上来的粉体或液体向下快速流动，并在连续按压头帽2时起到将粉体或液体不断向上提起的作用。凸块931的上表面成形为自下而上外径逐渐减小的第一弧面932，凸块931的下表面成形为自上而下外径逐渐减小的第二弧面933。第二弧面933可减小限流杆向下移动时对流体的挤压，第一弧面932可增大流体向下流动的面积进而增大阻力，有利于快速将流体向上提起。提取结构93b可一直延伸至杆体91b的下端部，且位于杆体91b下端部的凸块931可以仅具有第一弧面932的结构，该凸块931的下表面可以为平面。
导流结构92b为沿杆体91b长度方向延伸的螺旋筋921，将限流杆装配到喷头中后，上述螺旋筋921位于活塞6与泵体5中，螺旋筋921不仅可对流体起到导向作用，且螺旋筋921本身就可以减小其与泵体5之间的配合间隙，增大泵体5内的压力，进而增强对流体的挤压力，有利于流体以发散状喷出，扩大粉末或液体的喷射面。上述螺旋筋921为两条并在杆体91b周向上间隔布置。螺旋筋921边缘与杆体91b在二者的连接处平滑过渡。
使用本实施例的限流杆时，杆体91b随着喷头的头帽2上下移动，提取结构93b不断将粉末或液体向上提取，有利于确保喷头具有适宜的喷出量；杆体91b上部的导流结构92b一方面可对粉末或液体起到导流作用，另一方面，由于导流结构92b本身是凸设在杆体91b表面的，该导流结构92b使泵体5的出口变小，这就增大了泵体5内的压力，进而增大了内容物喷出状态下的分散度，有利于粉末或液体形成更大的喷散面。
