Description

201036702 六、發明說明： 【發明所屬之技術領域】 此申請案主張2008年12月18日提出的美國專利申 請案序號第6 1 / 1 3 8,769號之利益，其內容係以引用的方式 倂入本文中。 【先前技術】 Q 訂約人使用一不斷地改變其流體針狀物及出自於該噴 槍之噴嘴的HVLP渦輪噴槍。 【發明內容】 由於HVLP及其他噴槍中之高頻率變化，使用者需要 一簡單、免工具方式，以改變其流體針狀物及出自於該噴 槍之噴嘴，而不會冒著空氣通道及密封件污染之風險。爲 達成此，一滑動栓銷組件被導入，而允許該針狀物/扳機 Q 作動以被嚙合及解開。再者，該流體噴嘴已設有滾紋’以 提供省力的移除。 此噴槍之結構包括一滑動栓銷、扳機、針狀物、及流 體噴嘴。該扳機具有具有與該交叉動作滑動栓銷之直徑互 相作用的鍵槽形構造。當該滑動栓銷係於該噴灑位置中時 ，該滑動栓銷之較大直徑被定位在該扳機鍵槽構造之該較 大直徑中。當該滑動栓銷被垂直於該噴槍之方位推至該移 除位置時，該滑動栓銷之該較小直徑允許該扳機鍵槽構造 之較小直徑下降，藉此解除該流體針狀物之作動。 201036702 此組件完全地消除流體污染空氣通道及密封件之可能 性。而該工業標準之先前技藝設計幾乎確保此污染。 對此組件之噴嘴壓滾紋將允許使用者沒有工具地組裝 此零組件。此設計完全地消除任何需要，以移去該扳機， 或使用任何用於清潔或更換該針狀物及噴嘴之工具。 本發明之這些及其他目的與優點將會同所附圖面由以 下之敘述更充分地顯現，其中類似參考字母意指遍及該等 視圖之相同或類似的零件。 【實施方式】 此噴槍1 〇之結構包括一扳機滑動栓銷1 2、扳機1 4、 針狀物1 6、流體噴嘴1 8、及氣帽20。該扳機14具有與該 交叉動作滑動栓銷12之直徑互相作用的鍵槽形孔口 14a。 當該滑動栓銷1 2係在該噴灑位置中時，該滑動栓銷1 2之 較大直徑12a被定位在該扳機鍵槽構造14a之該較大直徑 中（圖2B與4)。當該滑動栓銷12被垂直於該噴槍10之方 位推至該移除位置時，該滑動栓銷12之該較小直徑12b 允許該扳機鍵槽構造1 4a之較小直徑下降，藉此解除該流 體針狀物16之作動（圖2A與3)。 對此組件之噴嘴1 8壓滾紋將允許使用者沒有工具地 組裝此零組件。此設計完全地消除任何移去該扳機1 4的 需要，或使用任何用於清潔或更換該針狀物16及噴嘴18 之工具。 其係考慮可對該噴槍作成各種變化及修改，而不會由 -6- 201036702 本發明之精神與範圍脫離，如藉由以下申請專利範圍所界 定者。 【圖式簡單說明】 圖1顯示一利用本發明的噴槍之前端的分解視圖。 圖2A顯示在該針狀物移除位置中之扳機滑動件。 圖2B顯示在該噴灑位置中之扳機滑動件。 0 圖3顯示在該針狀物移除位置中之扳機滑動件。 圖4顯示在該噴灑位置滑動中之扳機滑動件。 【主要元件符號說明】 1 〇 :噴槍 1 2 :滑動栓銷 1 2 a :較大直徑 1 2b :較小直徑 ❹ 14 :扳機 14a :鍵槽構造 1 6 :針狀物 1 8 :流體噴嘴 20 :氣帽

Claims (1)

  1. 201036702 七、申請專利範圍： 1 · 一種噴槍，具有一扳機，一針狀物及一流體噴嘴’ 其特徵包括： 於該扳機中之至少一鍵槽形構造，該鍵槽構造包括一 較大直徑部份及一較小直徑部份；及 一滑動栓銷，用於可解除地嚙合該扳機及該針狀物， 並可於一噴灑位置及一移除位置之間運動，該滑動栓銷具 有一較大直徑部份及一縮減直徑部份，藉此當該滑動栓銷 0 係在該噴灑位置中時，該滑動栓銷之較大直徑被定位在該 扳機鍵槽構造之該較大直徑中，且當該滑動栓銷被垂直於 該針狀物推至該移除位置時，該滑動栓銷之該較小直徑允 許該扳機鍵槽構造之較小直徑下降’藉此解除該流體針狀 物之作動。 2 .如申請專利範圍第1項之噴槍，其中該流體噴嘴係 有滾紋的。 〇
