Description
本創作係涉及空氣壓縮機的技術領域,尤其是涉及空氣壓縮機汽缸內可進行上衝及下衝行程的活塞體及其進氣阻片。 The present invention relates to the technical field of air compressors, in particular, to a piston body and its intake blocking plate that can perform upstroke and downstroke strokes in the cylinder of the air compressor.
空氣壓縮機之主要結構是藉由一馬達驅動一活塞體在汽缸內進行往復式之壓縮動作,被壓縮之空氣則可由汽缸輸送至儲氣座內,再由儲氣座上之歧管所連接之傳輸軟管連接至待充氣物品上,習知活塞體在活塞頭係設有被上下貫穿之空氣通道,而活塞頭頂端平面在空氣通道上覆設有一進氣阻片,在空氣壓縮機於停機的狀態下,該進氣阻片係封閉住活塞頭之空氣通道,當空氣壓縮機在前次運轉後,因活塞頭圓形周邊設置的氣密環以及進氣阻片封閉活塞頭之空氣通道所形成的氣密性,使得殘餘在汽缸內的高壓空氣無法排出,而當空氣壓縮機再次啟動時,活塞體在開始壓縮的進程就撞擊殘留在汽缸內的高壓空氣,使其瞬間增加空氣壓縮機的負載及電流竄升,致使空氣壓縮機壽命折損。為求改善習知缺失,是故,本創作人發展出一種在空氣壓縮機於停機的狀態下,該活塞頭之頂端面與進氣阻片之間係形成有一小角度通氣空間,當空氣壓縮機在運作完畢結束後,該殘留在汽缸內的壓縮空氣可由通氣空間經由空氣通道排出,使汽缸中的壓力與周圍大氣平衡,致令空氣壓縮機再次啟動後其活塞體於上衝行程時不會有額外的阻力,避免瞬間增加的壓縮負載及電流竄升,致使活塞體在汽缸內進行往復運動時能維持順暢的壓縮效能,且更兼具使用安全性及延長其使用壽命,並能更輕鬆快速地將待充氣物充足氣體。 The main structure of the air compressor is to use a motor to drive a piston body to perform a reciprocating compression action in the cylinder. The compressed air can be transported from the cylinder to the air storage seat, and then connected by the manifold on the air storage seat. The transmission hose is connected to the object to be inflated. In the conventional piston body, the piston head is provided with an air passage that is penetrated up and down, and the top plane of the piston head is covered with an air inlet blocking piece on the air passage. In the state of shutdown, the air intake blocking plate closes the air passage of the piston head. When the air compressor is in the previous operation, the air tight ring set around the circular circumference of the piston head and the air intake blocking plate close the air in the piston head. The air tightness formed by the channel makes it impossible for the high-pressure air remaining in the cylinder to be discharged, and when the air compressor starts again, the piston body hits the high-pressure air remaining in the cylinder when it starts to compress, causing it to increase the air instantly. The load and current of the compressor surge, resulting in the loss of the life of the air compressor. In order to improve the lack of conventional knowledge, therefore, the author developed a kind of ventilation space with a small angle between the top surface of the piston head and the air intake resistance plate when the air compressor is in the stopped state. After the operation of the compressor is completed, the compressed air remaining in the cylinder can be discharged from the ventilation space through the air passage, so that the pressure in the cylinder is balanced with the surrounding atmosphere, so that the piston body of the air compressor does not work during the upstroke after restarting. There will be additional resistance to avoid the instantaneous increase of compression load and current surge, so that the piston body can maintain smooth compression performance when reciprocating in the cylinder, and it is more safe to use and prolong its service life, and can be more Easily and quickly fill up the object to be inflated.

On the top plane, the other side is the action area that can cover the intake passage of the piston body. The action area of the air intake block and the positioning area of the intake block take the bending section as the axis of the phase boundary to make the intake resistance. The outer surface of the plate forms an obtuse angle of less than 180 degrees in a structural state, and at the same time, the inward surface of the air intake blocking plate naturally forms a small angle θ with the top plane of the piston head, forming a ventilation space Z, the aforesaid The piston rod extending below the axis of the piston head has a hole, and a spring is sleeved on the upright column tip at the bottom end.

本創作之空氣壓縮機10所安裝的活塞體在其活塞頭21安裝有一進氣阻片7,該進氣阻片7設有一摺曲段71,該摺曲段71並非隨意式將一進氣阻片7彎折使具有彎折角以形成本說明書中之彎摺軌線711,而是精確地應用機械工藝將一進氣阻片7預成一具有彎折角度以形成摺曲段71及其所附屬的彎摺軌線711,不論是一個或是多個彎摺軌線,多個彎摺軌線即是摺
曲段71內含有彎摺軌線711、第二彎摺軌線712及第三彎摺軌線713(可參考第四圖)以因應空氣壓縮機之不同大小之輸出功率的需求,當外來壓力作用於進氣阻片7時可將進氣阻片7之應力依循既定的彎摺軌線711(或言軌道)進行上下啟閉動作,在摺曲段71之一側設為定位區72可做為裝設在前述活塞頭21上,亦即活塞頭21設有二相分離的固定銷211、212,相對於固定銷211、212在進氣阻片7之定位區72則設有相分離之圓孔721、722,利用進氣阻片7之圓孔721、722分別定位在活塞頭21之固定銷211、212,致令進氣阻片7可牢固地定位在活塞頭21上。前述進氣阻片7在摺曲段71的另一側則為作用區73,該作用區73可覆蓋活塞體之進氣通道23,前述進氣阻片7的作用區73與進氣阻片7的定位區72以摺曲段71為相界之軸線而使進氣阻片7之正向面(即上衝動作時之進氣阻片7朝向汽缸13頂的上表面)形成一小於180度之鈍角的構造狀態,同時讓進氣阻片7的作用區73在背向汽缸13頂之背向面自然而然與前述活塞頭21頂端平面210形成一小角度θ的開啟狀態,形成一通氣空間Z,可同時參考第三及四圖,使空氣壓縮機10的活塞體在停機靜止狀態下,進氣阻片7的作用區73相對該進氣通道23及空氣通道52係保持打開的狀態,同時因為在活塞桿5之窟洞50內設有一彈簧54,該彈簧54之另端亦抵觸於進氣阻片7的作用區73背面,讓進氣阻片7與活塞頭21頂端平面呈現一開啟狀態的通氣空間Z,基於進氣阻片7的摺曲段71之設計及彈簧54頂住進氣阻片7的作用區73的背向面,讓進氣阻片7的開啟動作或活塞頭21靜止不動的階段,進氣阻片7較能保持在順暢運作及保護下而避免彈性疲乏的發生,藉由活塞體的進氣通道23因暢通而使汽缸13中的壓力與周圍大氣平衡,讓空氣壓縮機10再次啟動後其活塞體於上衝行程時(如第五圖所示)不會有額外的阻力(背壓阻力),致使活塞體在汽缸13內進行往復運動時能維持順暢的壓縮效能,且更兼具使用安全性及延長其使用壽

述活塞頭81的頂端平面共同形成一小角度θ的開啟狀態,當空氣壓縮機的活塞體在停機靜止狀態下,由於彈簧54撐起進氣阻片9及第一彎摺軌線931讓進氣阻片9的作用區92呈開口角度θ,進氣阻片9的作用區92相對該活塞體之上下貫穿的進氣通道86係保持打開的狀態,藉由活塞體的進氣通道86與活塞桿88上端之空氣通道87相連通而使汽缸13中的壓力與周圍大氣平衡,讓空氣壓縮機再次啟動後其活塞體於上衝行程時不會有額外的阻力(背壓阻力),致使活塞體在汽缸13內進行往復運動時能維持順暢的壓縮效能,且更兼具使用安全性及延長其使用壽命,並能更輕鬆快速地將待充氣物充足氣體,更由於大功率輸出在進氣阻片9因具有多軌摺曲段93的設計使進氣阻片9整體進行上下振幅的開合動作更具有順暢功能且能保護整個進氣阻片9不受破壞。
