Description

空氣壓縮機Air compressor

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。The present invention relates to the technical field of air compressors, in particular to a piston capable of performing 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，習知活塞在活塞頭係設有被上下貫穿之空氣通道，而活塞頭頂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 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. The conventional piston is provided with an air channel that is penetrated up and down on the piston head, and the top plane of the piston head is covered with an air intake blocking plate on the air channel. When the air compressor is in a stopped state At the bottom, the air intake blocking sheet closes the air passage of the piston head. When the air compressor is in the previous operation, it is formed by the airtight ring arranged around the circular periphery of the piston head and the air intake blocking sheet closing the air passage of the piston head. The high-pressure air remaining in the cylinder cannot be discharged, and when the air compressor starts again, the piston hits the high-pressure air remaining in the cylinder in the process of starting compression, which instantly increases the load of the air compressor. And the current surges, resulting in the loss of 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 over, 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 after the air compressor starts again, its piston will not be in the upward stroke. There is extra resistance to avoid the instantaneous increase of compression load and current surge, so that the piston 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 easier and faster Place the object to be inflated with sufficient gas.

The intake blocking piece 7 is provided with a bending section 71 , and the bending section 71 has at least one bending trajectory. 711, in use, the bending section 71 can be provided with a plurality of bending trajectories to meet the output power requirements of different sizes of air compressors. It is folded to have a bending angle to form the bending trajectory 711 in this specification, but a mechanical process is precisely applied to pre-form an air intake baffle 7 with a bending angle to form the bending trajectory 711. When the external pressure acts When the air intake blocking piece 7 is used, the stress of the air intake blocking piece 7 can be opened and closed up and down according to the predetermined bending trajectory 711 (or rail), and a positioning area 72 can be set on one side of the bending trajectory 711 In order to be installed on the top plane of the aforementioned piston head 21, that is, the piston head 21 is provided with two-phase separated fixing pins, and relative to the fixing pins, in the positioning area 72 of the air intake resistance sheet 7, there is a phase-separated circular hole 721. , 722 , use the circular holes 721 and 722 of the intake blocking sheet 7 to locate the fixing pins of the piston head 21 respectively, so that the intake blocking sheet 7 can be firmly positioned on the piston head 21 . On the other side of the bending trajectory 711, the aforementioned air intake blocking piece 7 is an action area 73, which can cover the intake passage 23 of the piston, the action area 73 of the aforementioned intake air blocking piece 7 and the intake air blocking piece The positioning area 72 of 7 takes the bending trajectory 711 as the boundary axis, so that the positive surface of the intake blocking piece 7 (that is, the upper surface of the intake blocking piece 7 facing the top of the cylinder 13 during the upward rushing action) forms an angle of less than 180 degrees. At the same time, let the action area 73 of the intake block 7 naturally form an open state of a small angle θ with the top plane of the piston head 21 on the back surface facing away from the top of the cylinder 13, forming a ventilation space Z, When the piston of the air compressor 10 is in a stationary state, the action area 73 of the intake blocking plate 7 is kept open relative to the intake passage 23 and the air passage 52. There is a spring 54, and the other end of the spring 54 also abuts against the back of the action area 73 of the air intake resistance piece 7, so that the air intake resistance piece 7 and the top plane of the piston head 21 present an open ventilation space Z, based on the air intake resistance piece The design of the bending trajectory 711 of 7 and the back surface of the spring 54 against the action area 73 of the air intake resistance piece 7, so that the opening action of the air intake resistance piece 7 or the stage when the piston head 21 is stationary, the air intake resistance piece 7. It can maintain smooth operation and protection to avoid the occurrence of elastic fatigue. The pressure in the cylinder 13 is balanced with the surrounding atmosphere due to the smooth flow of the intake passage 23 of the piston, so that after the air compressor 10 starts again, the piston is at There is no additional resistance (back pressure resistance) during the upward stroke, so that the piston can maintain smooth compression performance when reciprocating in the cylinder 13, and it is safer to use, prolong its service life, and make it easier to use Quickly fill the object to be inflated with gas. Please refer to Figures 3 to 7, the action diagrams of the piston in the cylinder 13 during the upward stroke and the downward stroke. During the upward stroke of the piston, as shown in Figures 5 and 7, the spring 54 will be compressed and the intake resistance plate 7 will be closed. In the state of the intake passage 23, in the piston downstroke stage, the spring 54 will stretch and spread the intake blocking plate 7 away from the intake passage 23 to be in an open state, as shown in the fourth and sixth figures. The intake air blocking piece 7 and the bending trajectory 711 make the action area 73 of the air intake blocking piece 7 have an opening angle θ. The state is also shown in the third figure, so that the high-pressure air remaining in the cylinder 13 can pass through the ventilation space. Z. The intake passage 23 is balanced with the external atmospheric pressure, so that the back pressure of the intake blocking sheet 7 can be overcome when the piston operates again next time. The aforementioned air intake blocking piece 7 is provided with a through hole 731 in the action area 73 , and the aforementioned piston head 21 is provided with a limit hook 20 at a position corresponding to the through hole 731 and engages with the through hole 731 .

The length of the upright post 213 set by the limit hook 20 can be adapted to the air compressor. The power output is appropriately lengthened or shortened, so that the operating amplitude of the intake block 7 conforms to the working principle; when the piston is at rest, the action area 73 of the intake block 7 is connected to the top of the aforementioned piston head 21. In addition to the open state of the plane, there is a pre-opening angle θ and a ventilation space Z, and the through hole 731 of the air intake blocking piece 7 ends at the transverse column 214 of the aforementioned limit hook 20 .
