Description
技术领域
本发明涉及乳液喷头,是一种抗菌可降解内衬乳液喷头及其材料制备方法。
背景技术
乳液喷头是一种应用于乳液瓶或乳液泵的喷头装置,乳液瓶是一种用于储存乳液的容器,主要用于化妆品乳液的盛放;乳液泵是一种用于乳液挤出的泵体组立,其工作原理与微型喷雾器等泵体产品相近。泵芯为乳液瓶和乳液泵的主要部件之一,现有同类产品中的泵芯结构,如中国专利文献中披露的申请号201910739479.3,申请公布日2019.12.20,发明名称“改进型泵芯及其环保高新材料制备方法”,该泵芯的泵体外侧的阀杆外径与泵体外侧的内塞之间设有弹簧,其要点是该泵芯的泵体内阀杆外径套入内塞的内径,泵体的泵口内径与内塞的下塞口外径扣合固定密封,弹簧设置于阀杆上弹簧腔与内塞下弹簧腔套合的腔室内,弹簧处的阀杆外径设有均匀分别的竖直槽。但上述产品和同类产品中的外罩缺少内衬结构设计,跌落后防损坏或出液结构设计欠佳。
发明内容
为克服上述不足,本发明的目的是向本领域提供一种抗菌可降解内衬乳液喷头及其材料制备方法,使其解决现有同类产品的外罩缺少内衬结构设计,跌落后防损坏或出液结构设计欠佳,对应生产材料配比和制备方法有待改进的技术问题。其目的是通过如下技术方案实现的。
一种抗菌可降解内衬乳液喷头,该内衬乳液喷头的泵芯组立外径内塞处裙边扣合设置于大圈的内圈口内,大圈的外径圈外径套有氧化铝泵套,大圈的上圈口处圈口与氧化铝泵套的内弯口相抵,大圈的内圈口下方外径圈内壁设有瓶口内螺纹,内圈口上方的上圈口高出大圈的内圈口,PE双覆膜垫片设置于所述瓶口内螺纹处的内塞处裙边,泵芯组立的一端泵体中进水口处设有软吸管,泵芯组立的另一端阀杆中出水口与头帽的进水孔外径扣位筋扣合,头帽的底部帽口位于大圈的上圈口内;其结构设计要点是所述氧化铝泵套的外径套有外罩组立,外罩组立的外罩内设有内衬,内衬通过衬口外径的大圈径与外罩套合并抹胶固定,内衬的大圈径设有气密槽和衬通气槽,内衬的大圈径上方外径为小圈径,内衬的内径一侧设有凸起的扣合筋,内衬的扣合筋与氧化铝泵套的外径相抵套合,头帽上方的内衬顶部块槽内设有加重块,加重块通过内衬的块槽及块槽内径的凸筋固定于内衬,内衬的块槽为圆弧形对称设置的块槽筋,外罩、内衬、加重块连为一体构成外罩组立。该内衬乳液喷头的内衬与氧化铝泵套的外壁直伸过盈配合,使拔脱外罩时手感持久细腻,目前市场的同类产一般通过凹凸筋结构配合,拔脱时较为突兀、瞬间的手感。
所述大圈的外径圈处外径设有齿圈槽和圈通气槽,大圈的齿圈槽与氧化铝泵套内壁的内径条啮合。上述大圈的外径与氧化铝泵套的筋位凹凸配合,使氧化铝泵套无需用点胶就能完全固定于大圈,相比目前市场上同类产品采用点胶固定配合的方式,更为节能环保,便于回收利用。
所述大圈的齿圈槽处底部圈口设有向外翘起的齿口槽,氧化铝泵套的下套口内径设有内翻的限位卷边,大圈的齿口槽处边沿与氧化铝泵套内的限位卷边上方边沿扣合限位,氧化铝泵套的限位卷边为二级台阶限位卷边,齿口槽下方大圈设有二级内限位圈。上述大圈外翘的齿口槽与氧化铝泵套的限位卷边配合相扣,外圈与氧化铝泵套之间一体较为牢固。
所述泵芯组立的内塞处裙边设有内扣槽和外扣筋,内塞裙边的内扣槽与泵芯组立的泵体上泵口外径扣合,内塞的外扣筋与大圈的内圈口扣合,阀杆的头帽一端外径设有下弹簧槽,阀杆的下弹簧槽套入内塞的上弹簧槽,弹簧设置于阀杆的上弹簧槽和内塞的下弹簧槽构成的腔室内,弹簧的两端分别相抵于阀杆的上弹簧槽底部和阀杆外径的内塞下弹簧槽处圈口槽,阀针的头部圈槽与阀杆的内部圈筋扣合,并固定住阀针外径的活塞,阀杆的内部圈筋之间设有内通道,活塞的下圈筋与阀针的针密封槽相抵密封,活塞的上圈筋与阀杆的杆口内壁相抵密封,活塞的外径与泵体的内壁相抵密封,内塞的内沿圈套入泵体的泵口并扣合密封住泵体的内径和阀杆的外径,泵体内的进水口处设有弹套。上述为泵芯组立具体实施例。
所述大圈的外径省略氧化铝泵套,外罩组立的内衬与大圈的外径套合。上述为省略氧化铝泵套的结构实施例。
所述抗菌可降解材料由以下重量份的原料制成:80-200份聚丁二酸丁二醇酯、60-80份改性料聚乳酸、30-50份PHBH、10-20份改性玉米淀粉、5-20份增塑剂、4-10份纳米二氧化钛、4-10份抗菌剂、5-8份偶联剂、2-6份降解剂、1-5抗氧化剂、1-5份润滑剂和1-5份填充剂;所述重量份的原料,先将聚丁二酸丁二醇酯、改性料聚乳酸、PHBH、改性玉米淀粉混合后放入到干燥烘箱中进行烘干,得到烘干料;烘干温度为40-60℃,干燥时间为2-4h;接着将烘干料投入到高速混合机中,并依次投入增塑剂、偶联剂、降解剂、氧化剂、润滑剂和填充剂,在高速混合机中对原料进行混合,混合时间为20-30min;最后将高速混合机中的混合料加入到双螺杆挤出机中,挤出造粒,得到生物质降解材料;所述双螺杆挤出机的一区挤出温度为90-100℃,二区挤出温度为110-120℃,三区挤出温度为120-130℃。
所述增塑剂为环保增塑剂,环保增塑剂由主增塑剂和助增塑剂组成,二者比例为2:1,其中主增塑剂为对苯二甲酸二辛酯、偏苯三酸三辛酯的一种,助增塑剂为乙酰柠檬酸三丁酯、环氧大豆油、癸二酸二辛酯的一种;所述抗菌剂为沸石型纳米银离子抗菌剂,所述偶联剂为硅烷偶联剂KH-560,所述降解剂为聚羟基脂肪酸酯、改性环糊精,按照重量比2:1组成的混合物;所述抗氧化剂为BHA和PG以任意比混合而成。
本发明结构设计合理,生产、使用方便,密封性、牢固度好,意外跌落和包装后防撞、防损、抗撞效果好,制备方法可行;适合作为乳液瓶或乳液泵的乳液喷头使用,及其同类产品的结构改进。

上述泵芯组立的内塞504处裙边设有内扣槽和外扣筋5041,内塞裙边的内扣槽与泵芯组立的泵体501上泵口外径扣合,内塞的外扣筋与大圈的内圈口扣合,阀杆的头帽一端外径设有下弹簧槽,阀杆的下弹簧槽套入内塞的上弹簧槽,弹簧506设置于阀杆的上弹簧槽和内塞的下弹簧槽构成的腔室内,弹簧的两端分别相抵于阀杆的上弹簧槽底部和阀杆外径的内塞下弹簧槽处圈口槽,阀针502的头部圈槽与阀杆的内部圈筋扣合,并固定住阀针外径的活塞,阀杆的内部圈筋之间设有内通道,活塞的下圈筋与阀针的针密封槽相抵密封,活塞的上圈筋与阀杆的杆口内壁相抵密封,活塞的外径与泵体的内壁相抵密封,内塞的内沿圈套入泵体的泵口并扣合密封住泵体的内径和阀杆的外径,泵体内的进水口处设有弹套507。
该内衬乳液喷头的喷头组立装配步骤如下:先将大圈套入氧化铝泵套,大圈的上圈口702抵住氧化铝泵套的内弯口601平面,同时大圈外翘的齿口槽704扣入氧化铝泵套的限位卷边602处,使大圈上下相抵无法窜动;组装后大圈的外径圈703处莱丝式齿圈槽与氧化铝泵套的内径条603凹凸配合,使大圈配氧化铝泵套无法相对转动,起到止转作用。再将泵芯组立中内塞处外径的外扣筋5041装入大圈的内圈口701上,两者扣位配合,将垫片的内孔装入泵芯的泵体外径内塞裙边下方,垫片与泵体的外径之间过盈配合,使垫片固定在泵芯组立上;再将软吸管内孔插入到泵芯组立的进水口处外径,最后将头帽的扣位筋401装入泵芯组立的出水口5051处扣位中。外罩组立的装配步骤如下:先将加重块外周嵌入到内衬的块槽筋303筋位内切圆中,两者过盈配合,再将内衬的大圈径301与外罩的内壁配合并抹胶固定,最后将组装好的外罩组立套入到大圈组立,此时外罩组立的扣合筋302与氧化铝泵套的外壁直伸过盈配合,到此产品组装完成。使用时,先把外罩组立取下,然后按压头帽取液使用;关闭时,取完液体后,把外罩组立套回原位置即可。
