全塑手扣喷雾器改进结构
技术领域
本发明涉及喷雾器， 是一种全塑手扣喷雾器改进结构。
背景技术
目前， 市场上销售的喷雾器产品很多， 其主要利用伯努利原理： 同一流质中， 流速大， 压强小； 流速小， 压强大。 这些喷雾器产品中的手扣式喷雾器广泛地应用于家庭花木防治、 家庭卫生杀虫、 家用洗涤剂喷洒等领域， 其中一些手扣式喷雾器为了方便环保和回收利用， 喷雾器的零部件全部采用塑料制成。 如中国专利文献刊载的专利号 ZL200820168435. 7, 授权 公告日 2009年 9月 23日， 实用新型名称 "全塑喷枪" ， 其设计要点在于所述的头帽与主体的出 水孔连接， 连接处设有塑料引阀、 分水头， 闷盖设有塑料弹套， 闷盖过盈套入主体的进水孔， 扳手与活塞之间设有塑料弹簧， 活塞过盈套入主体的缸体内径。 再如中国专利文献刊载的申 请号 200810162271. 1， 公开日 2009年 4月 29日， 发明名称 "全塑手扣式喷雾器" ， 其设计要点 是主体与扳手之间设置塑料弹簧， 塑料弹簧两端分别与连接扳手、 主体相抵， 活塞套入缸体, 球面杆与扳手扣接； 引阀呈半圆形， 引阀、 分水头套入主体的出水口， 引阔的定位槽、 分水 头的定位孔分别与主体连接， 分水头的端面与引阀的定位片相抵； 弹套与闷盖相扣， 设置于 主体进水孔的腔道中。 但其不足之处在于： 塑料弹簧设置与活塞与扳手之间， 塑料弹簧呈弓 形， 经常使用后塑料弹簧容易发生形变、 断裂， 以及塑料弹簧脱离主体， 扳手组装较为不便 的现象。
发明内容
为克服上述存在的不足， 本发明目的是向本领域提供一种全塑手扣喷雾器改进结构， 为 了使现有全塑手扣式喷雾器结构设计更稳定， 扳芋按压效果更好、 组装更简便的技术问题而 设计的， 其目的是通过如下技术方案实现的。
一种全塑手扣喷雾器改进结构， 该喷雾器包括泵头部分和泵身部分， 泵头部分包括： 头 帽、 分水头、 引阀， 泵身部分包括： 主体、 罩壳、 塑料弹簧、 活塞、 弹套、 闷盖、 大圈、 垫 片、 小闷盖、 吸管套、 吸管、 扳手； 所述扳手的固定孔固定于主体的扳手销， 扳手与活塞扣 合， 按压扳手， 扳手围绕固定的扳手销端作圆弧滑动运动， 扳手的圆弧滑动运动转化为活塞 的水平滑动运动。 其设计要点是所述主体的缸体与活塞之间设有塑料弹簧。 现有非全塑手扣 式喷雾器的金属弹簧也是设置于主体缸体与活塞之间， 通 按压扳手， 使扳手的圆弧滑动运 动转化为活塞的水平滑动运动： 同时， 根据伯努利原理将液体从泵头部分喷出。 虽然该全塑 手扣喷雾器中塑料弹簧的位置与现有非全塑手扣式喷雾器中金属弹簧的位置相同， 但其主体 和塑料弹簧采用新型材料， 即将金属弹簧改进为塑料弹簧， 同时对塑料弹簧、 活塞、 主体的 结构进行了相应的改进， 克服了原有全塑手扣喷雾器中弓形塑料弹簧的技术问题， 实现了塑 料弹簧取代金属弹簧的目的。
所述塑料弹簧呈圆筒形， 一端面设有开口， 开口端的内径设有凸筋， 另一端面设有盲面， 盲面呈圆弧形。 通过在塑料弹簧的圆弧形盲面施加外力， 使塑料弹簧中圆弧形的盲面发生形 变， 外力带动活塞水平向主体的缸体内侧作滑动运动； 释放外力后， 塑料弹簧的圆弧形盲面 恢复原状， 产生的弹力带动活塞水平向主体的缸体外侧作滑动运动。 根据上述塑料弹簧的工 作原理， 其可以设计为圆锥形等其他形状， 但圆筒形的塑料弹簧效果较好， 为优选技术方案。
所述活塞呈圆筒形， 中间设有隔层， 隔层一侧设有弹簧扣位， 另一侧的活塞口设有扳手 支点抵位面， 外径设有密封段。 活塞^弹簧扣位用于塑料弹簧的固定； 扳手支点抵位面用于 扳手的固定； 密封段作用与现有活塞作用相同， 用于主体内腔与外界的隔离;
所述活塞的外径设有两道密封段。 两层的密封段设计进一步的保证了主体内腔与外界的 隔离。
根据上述活塞的结构特征， 所述活塞的隔层另一侧或设有球面杆， 球面杆与扳手的弧形 扣位扣合。在活塞内隔层一侧设有固定塑料弹簧的弹簧扣位， 活塞外径设有密封段的前提下， 对活塞的扳手支点抵位面进行上述结构改进， 亦可达到相同的技术效果。
所述塑料弹簧的开口端套入活塞， 塑料弹簧的凸筋与活塞的弹簧扣位扣合， 塑料弹簧的 盲面与主体的弹簧支撑销相抵。 塑料弹簧的凸筋、 活塞的弹簧扣位作用于防止塑料弹簧与活 塞之间的脱落， 塑料弹簧的盲面、 主体的弹簧支撑销作用于塑料弹簧与主体之间水平运动时 产生弹力。
所述活塞套入主体的缸体， 活塞的密封段与主体的缸体内径过盈配合， 活塞中扳手支点 抵位面的内孔与扳手的扳手凸棱扣合。 活塞的密封段与主体的缸体内径过盈配合方便了活塞 的装卸， 扳手支点抵位面的内孔与扳手的扳手凸棱作用于防止活塞与扳手之间的脱落。
所述扳手与活塞连接处设有圆弧支点， 圆弧支点设有扳手凸棱。 扳手与活塞连接处的圆 弧支点、 扳手凸棱作用于平行推动活塞作水平滑动运动， 并防止活塞与扳手之间的脱落， 方 便了扳手的圆弧滑动运动转化为活塞的水平滑动运动。
经上述的改进， 使本发明设计较为合理， 解决了现有同类产品经改进解决塑料弹簧容易 发生形变、 断裂， 以及塑料弹簧脱离主体或扳手的技术问题， 简化了产品结构， 方便了装配， 提高了使用寿命， 环保回收方便， 适用于手扣式喷雾器和同类产品的结构改进。

具体实施方式：
现结合附图对该喷雾器的主要结构特征、 工作原理和使用做进一步描述。 该喷雾器的主 要结构特征是： 该喷雾器中活塞 7与主体 4的缸体 403之间设有塑料弹簧 6， 塑料弹簧的结构与 现有金属弹簧、 原有弓形塑料弹簧的结构完全不同， 同时与塑料弹簧对应的主体、 活塞两个 部件也进行了改进。 如图 6、 图 7所示， 所述塑料弹簧为圆筒形， 一端面设有盲面 601， 盲面为 塑料弹簧的定位端和主要形变端； 另一端面设有开口， 开口端的内径设有凸筋 602。 如图 2、 图 3所示，所述主体的缸体 403内设有弹簧支撑销 402。如图 4、图 5所示，所述活塞也为圆筒形， 活塞内隔层一侧面设有弹簧扣位 702, 另一侧面的开口处设有扳手支点抵位面 701， 活塞的外 径设有密封段 703。 如图 8、 图 9所示， 扳手一端设有固定孔 1501， 扳手设有圆弧支点 1502， 圆 弧支点设有扳手凸棱 1503。 如图 1所示， 塑料弹簧套入活塞， 塑料弹簧的凸筋与活塞的弹簧扣 位扣合； 接着将活塞和塑料弹簧套入主体的缸体， 活塞的密封段与主体中缸体内径过盈配合， 塑料弹簧的盲面与主体的弹簧支撑销相抵；最后将已经一端固定于主体上扳手销 401的扳手靠 向活塞， 扳手上圆弧支点的扳手凸棱与活塞中扳手支点抵位面的内孔扣合， 扳手上圆弧支点 的扳手凸棱抵住活塞的扳手支点抵位面， 扳手凸棱与扳手支点抵位面的内孔扣合， 该喷雾器 的主要结构特征即可安装完毕。 其工作原理是： 通过按压扳手， 将扳手的圆弧滑动运动转化 为活塞的水平滑动运动。 使用前将吸管 14***盛有液体的容器内， 吸管伸入液体， 大圈 10与容器瓶口旋紧， 垫片 11与容器的瓶口密封， 主体与容器构成封闭状态， 将头帽 1转动至开启状态。数次往复扣压扳 手， 容器内的压强递增， 液体自动从容器内进入主体的腔体内。 继续扣压扳手， 扳手带动活 塞向主体中缸体的内侧移动， 塑料弹簧一侧的圆弧形盲面受力发生形变。 缸体内高速推入的 气体进入主体， 弹套 8关闭， 引阀 3开启。 主体内的低速流体被缸体内高速推入的气体冲成水 滴， 并经过主体的空腔流向头帽 1， 被主体出口处的分水头 2阻挡后， ^引阀呈雾状从头帽喷 出。 松开扳手， 塑料弹簧的圆弧形盲面恢复原状， 产生的弹力带动活塞向缸体的外侧相反方 向移动， 活塞带动扳手移动。 此时， 引阀关闭， 弹套开启， 液体继续自动流入吸管， 经吸管 套 13、 小闷盖 12、 闷盖 9, 流入主体的腔体内， 即利用伯努利原理工作。 继续往复扣压扳手， 扳手的圆弧往复滑动运动转化为活塞的水平往复滑动运动， 即可不断喷洒液体。
根据上述技术特点， 如图 10所示， 对活塞进行一些改进亦可达到相同的技术效果， 具体 是： 活塞中隔层设有弹簧扣位的另一侧设置球面杆 704,活塞的球面杆与扳手的弧形扣位 1504 扣合。 同时， 活塞的扳手支点抵位面或设有与扳手相同的圆弧支点， 活塞的圆弧支点设有扳 手凸棱， 扳手凸棱***扳手的圆弧支点， 通过扳手和活塞两侧的圆弧支点， 亦可将扳手的圆 弧滑动运动转化为活塞的水平滑动运动。
