Description

空氣壓縮機之汽缸內的活塞體Piston body in the cylinder of air compressor

本發明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。The present invention relates to the technical field of air compressors, and in particular to a piston body capable of upward and downward strokes in a cylinder of an 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，使汽缸內與外界環境的空氣相流通，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，而每當空氣壓縮機由靜止狀態重新啟動時，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殘壓造成活塞體推進時的阻力增加而形成高電流突波的效應，使傳統汽車電源在使用時會因高電流突波致使保險絲熔斷而停止工作，進而在目前響應環保概念的電動車的發展趨勢而論，智慧型電動汽車在其微電腦系統對於電力使用的保護機制的要求下，當高電流突波發生時會立即截斷電源輸出，導致當下空氣壓縮機停止工作，失去功能。是以有鑑於此，本發明人發展出一種在空氣壓縮機於停機的狀態下，該活塞頭之頂端平面與進氣阻片之間係形成有一間隙，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該間隙經由進氣通道及空氣通道排出，而使汽缸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阻礙，避免瞬間高電流突波的產生，致使活塞體在汽缸內進行往復運動時能增益順暢的壓縮效能，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，讓空氣壓縮機在任何壓力停機時能輕易啟動，更不會造成傳統汽車電源因高電流突波而熔斷保險絲，或是智慧型電動汽車在其微電腦系統對於電力使用的保護機制的要求下，當高電流突波發生時會立即截斷電源輸出，導致當下空氣壓縮機停止工作，失去功能。The main structure of the air compressor is to use a motor to drive a piston body to perform 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. It is known that the piston body is provided with an air channel that penetrates up and down on the piston head to allow the air in the cylinder to communicate with the external environment. The top plane of the piston is covered with an air channel. The air inlet blocker blocks the air passage of the piston head when the air compressor is in a stopped state. Whenever the air compressor is restarted from a static state, the air inlet blocker is installed around the circular periphery of the piston head. The air tightness formed by the air sealing ring and the air intake blocker closing the air passage of the piston head causes the residual pressure in the cylinder to increase the resistance when the piston body is pushed forward and form a high current surge effect, which makes the traditional automobile power supply When in use, a high current surge will cause the fuse to blow and stop working. In view of the current development trend of electric vehicles that respond to the concept of environmental protection, smart electric vehicles require a protection mechanism for power use in their microcomputer systems. When a high current surge occurs, the power output will be cut off immediately, causing the air compressor to stop working and lose its function. Therefore, in view of this, the inventor developed a method that when the air compressor is in a stopped state, a gap is formed between the top plane of the piston head and the air inlet blocker. When the air compressor is finished operating, The compressed air remaining in the cylinder can be discharged from the gap through the intake passage and the air passage, so that the pressure in the cylinder is balanced with the surrounding atmosphere, so that the piston body will not be hindered in the upward stroke after the air compressor is restarted. , to avoid the generation of instantaneous high current surges, so that the piston body can gain smooth compression performance when it reciprocates in the cylinder, and it is also safer to use and extends its service life, and can more easily and quickly inflate the object. Sufficient gas allows the air compressor to be easily started when any pressure shuts down, and it will not cause the traditional car power supply to blow out the fuse due to high current surges, or the protection mechanism requirements of smart electric vehicles on their microcomputer systems for power usage. When a high current surge occurs, the power output will be cut off immediately, causing the air compressor to stop working and lose its function.

本發明之主要目的係提供一種空氣壓縮機之汽缸內的活塞體，特別是指該活塞體之活塞頭頂端設有一上下貫通之進氣通道，該進氣通道的外圍在該活塞頭頂面形成有一平坦板面，該平坦板面上設有至少一個具有高度的凸體，該凸體與被固定在活塞頭上的進氣阻片相抵觸，以使該進氣阻片與前述活塞頭的平坦板面間形成一間隙的狀態，該進氣通道因暢通而使汽缸中的壓力與外界大氣壓力相平衡，於該活塞體處於靜態時，能使殘存於汽缸內的殘餘壓力得以疏泄而出。The main purpose of the present invention is to provide a piston body in the cylinder of an air compressor. In particular, the top end of the piston head of the piston body is provided with an air inlet passage that penetrates up and down. The periphery of the air inlet passage is formed with an air inlet on the top of the piston head. A flat plate with at least one convex body having a height that conflicts with the air inlet blocker fixed on the piston head, so that the air inlet blocker is in contact with the flat plate of the piston head. A gap is formed between the surfaces, and the smooth air intake passage allows the pressure in the cylinder to balance with the external atmospheric pressure. When the piston body is in a static state, the residual pressure remaining in the cylinder can be released.

本發明之另一主要目的，其係提供一種活塞體的構造，該活塞體之活塞頭頂端之平坦板面所設至少一個具有高度且凸出該平坦板面的凸體可為不同的形狀及不同體積大小，唯要該等凸體係由前述平坦板面以朝垂直的方向凸出並具有高度，使前述活塞頭與前述進氣阻片二者之間形成一間隙。Another main object of the present invention is to provide a structure of a piston body.

Different sizes, as long as the convex system protrudes from the flat plate surface in a vertical direction and has a height so that a gap is formed between the piston head and the air inlet blocker.

本發明之再一主要目的，其係提供一種活塞體的構造，該活塞頭形成的間隙，足讓汽缸內的殘餘壓力疏泄排出，使每一次的壓縮行程啟始或是靜止狀態再重新啟動時，可防止因汽缸內的殘餘壓力造成活塞體上衝推進時的阻力增加而形成的高電流突波的效應，可直接避免空氣壓縮機在連接傳統汽車電源使用時，因高電流突波致使保險絲熔斷而停止工作，或者因為純環保電動汽車因其微電腦系統對於電力使用的保護機制而在高電流突波發生時立即截斷電源輸出，以致空氣壓縮機被停止工作，失去功能者。Another main object of the present invention is to provide a structure of the piston body. The gap formed by the piston head is enough to allow the residual pressure in the cylinder to be vented and discharged, so that each compression stroke can be started or restarted in a static state. It can prevent the effect of high current surge caused by the residual pressure in the cylinder causing the increase of resistance when the piston body rushes upward. It can directly prevent the air compressor from being caused by high current surge when it is connected to the traditional automobile power supply. The fuse is blown and stops working, or the environmentally friendly electric vehicle's microcomputer system's protection mechanism for power usage immediately cuts off the power output when a high current surge occurs, causing the air compressor to stop working and lose its function.

However, these are in the current state of use, so they are not shown in the figure. The detailed structure will not be elaborated in detail, but will be stated here first.

本發明最主要結構特徵乃是空氣壓縮機10的活塞體2之活塞頭21頂端之平坦板面5上設有至少一個具有高度且凸出該平坦板面5的凸體，該凸體可為不同的形狀及不同體積大小，唯要該等凸體係由前述平坦板面5以朝垂直的方向凸出並具有高度，使前述活塞頭21與一進氣阻片7二者之間形成一間隙51，前述凸體係設在被前述進氣阻片7所覆蓋的平坦板面5的範圍內，該間隙51足讓汽缸13內的殘餘壓力疏泄排出，使每一次的壓縮行程啟始或是靜止狀態再重新啟動時，可防止因汽缸13內的殘餘壓力造成活塞體2上衝推進時的阻力增加而形成的高電流突波的效應，可直接避免空氣壓縮機10在連接傳統汽車電源使用時，因高電流突波致使保險絲熔斷而停止工作，或者因為純環保電動汽車因其微電腦系統對於電力使用的保護機制而在高電流突波發生時立即截斷電源輸出，以致空氣壓縮機10被停止工作，失去功能。The most important structural feature of the present invention is that the flat plate surface 5 at the top of the piston head 21 of the piston body 2 of the air compressor 10 is provided with at least one convex body with a height that protrudes from the flat plate surface 5. The convex body can be Different shapes and different sizes, as long as the convex system protrudes from the aforementioned flat plate surface 5 in a vertical direction and has a height so that a gap is formed between the aforementioned piston head 21 and an air inlet blocker 7 51. The aforementioned convex system is located within the range of the flat plate surface 5 covered by the aforementioned air inlet blocker 7.

Work, lose function.

本發明在活塞頭21頂面所設至少一個凸體的技術特徵，茲再以實施例說明如后。請參閱第一至五圖所示，本發明之空氣壓縮機10之汽缸13內的活塞體2，其包含有一活塞頭21及其相連結的活塞桿4，該活塞頭21頂端設有一上下貫通之進氣通道23，而活塞頭21頂面形成有一平坦板面5，於該活塞頭21頂端之一側邊設有二相分離的固定銷211、212、一含有定位凸垣214之T型凸塊213介於前述固定銷211、212之間，於該活塞頭21頂端的另一側邊則設有一限位卡鈎22。前述活塞頭21以T型凸塊213及限位卡鈎22為中心線的二側邊之平坦板面5上可分別設一凸體215、216，該等凸體215、216以相對稱設立為最佳，該凸體215、216為條狀型。前述凸體215、216高出該平坦板面5之水平面高度但低於該限位卡鈎22的豎立柱221高度，前述活塞頭21外周圍邊安裝有一氣密環3，該氣密環3在空氣壓縮機10的操作中實現圍繞活塞體2及汽缸13內表面的持續密封。前述活塞頭21往下延伸的活塞桿4，該活塞桿4下端設有一圓孔41而與傳動機構14中之曲軸141相樞固，前述活塞桿4上端則設有一可與大氣連通之空氣通道42，使前述進氣通道23和空氣通道42相連通。一進氣阻片7係可被設置在前述活塞頭21的平坦板面5上，其一端係固定在平坦板面5的固定銷211、212上，由於T型凸塊213的定位凸垣214可契合進氣阻片7的凹陷狀卡槽721，因此目前均以AI機器人作組裝工作時容易辨識而不會有反裝、反置的情況產生，有利於產品的組裝效率。當空氣壓縮機10於停機的狀態下，該進氣阻片7抵觸於平坦板面5上的二凸體215、216而使進氣阻片7與平坦板面5存有一間隙51，該進氣通道23因暢通而使汽缸13中的壓力與外界大氣壓力相平衡，於該活塞體2處於靜態時，致令殘存於汽缸13內的殘餘壓力得以疏泄而出，如第三圖所示。The technical features of at least one convex body provided on the top surface of the piston head 21 of the present invention will be described below with examples. Please refer to Figures 1 to 5. The piston body 2 in the cylinder 13 of the air compressor 10 of the present invention includes a piston head 21 and a connected piston rod 4. The top of the piston head 21 is provided with an up and down through The air inlet passage 23, and the top surface of the piston head 21 is formed with a flat plate surface 5. On one side of the top of the piston head 21, there are two phase-separated fixing pins 211, 212 and a T-shaped positioning convex wall 214. The protrusion 213 is between the aforementioned fixing pins 211 and 212, and a limiting hook 22 is provided on the other side of the top of the piston head 21. The flat plate surface 5 of the two sides of the aforementioned piston head 21 with the T-shaped protrusion 213 and the limiting hook 22 as the center line can be respectively provided with a protrusion 215, 216. The protrusions 215, 216 are set up in a relatively symmetrical manner. Most preferably, the protrusions 215 and 216 are strip-shaped. The aforementioned protrusions 215 and 216 are higher than the horizontal height of the flat plate surface 5 but lower than the height of the upright column 221 of the limiting hook 22. An airtight ring 3 is installed around the outer periphery of the aforementioned piston head 21. The airtight ring 3 During operation of the air compressor 10 a continuous sealing is achieved around the inner surface of the piston body 2 and the cylinder 13 . The piston rod 4 extends downward from the piston head 21. The lower end of the piston rod 4 is provided with a round hole 41 and is pivotally connected to the crankshaft 141 in the transmission mechanism 14. The upper end of the piston rod 4 is provided with an air passage that can communicate with the atmosphere. 42. Connect the aforementioned air inlet channel 23 and the air channel 42. An air intake blocker 7 can be arranged on the flat plate surface 5 of the aforementioned piston head 21, and one end thereof is fixed on the fixing pins 211, 212 of the flat plate surface 5. Due to the positioning boss 214 of the T-shaped bump 213 It can fit into the concave slot 721 of the air inlet blocker 7, so it is easy to identify when AI robots are currently used for assembly work, and there will be no reverse installation or inversion, which is beneficial to the assembly efficiency of the product. When the air compressor 10 is in a stopped state, the air inlet blocking piece 7 resists the two protrusions 215 and 216 on the flat plate 5 so that there is a gap 51 between the air inlet blocking piece 7 and the flat plate 5. Because the air passage 23 is unobstructed, the pressure in the cylinder 13 is balanced with the external atmospheric pressure. When the piston body 2 is in a static state, the residual pressure remaining in the cylinder 13 can be released, as shown in the third figure. .

請參閱第一及二圖所示，本發明之進氣阻片7在其內圍實體上鏤穿一非全圓式之環狀形內空區71，並將進氣阻片7細分為外環分片72及內圓分片73兩部分，該外環分片72與內圓分片73在相連結處形成一頸段74，前述進氣阻片7在靠近於頸段74之外環分片72上設有一貫穿的貫穿孔75，前述活塞頭21在相對應於該貫穿孔75的位置設有前述限位卡鈎22並與該貫穿孔75相嵌扣，而相對於前述活塞頭21上的二固定銷211、212則在進氣阻片7上設有相分離之圓孔76、77，利用進氣阻片7之圓孔76、77分別定位在活塞頭21之固定銷211、212，且同時藉由前述活塞頭21之T型凸塊213抵靠在進氣阻片7之外環分片72外緣，而前述T型凸塊213之定位凸垣214卡納於該進氣阻片7之外環分片72外緣的凹陷狀卡槽721，致令進氣阻片7可牢固地定位在活塞頭21上，而該T型凸塊213之定位凸垣214的構造係可作為該進氣阻片7在組裝作業中用來辨別安裝定位方向的功能，因為若是反向組裝該進氣阻片7可能對活塞體2的功能產生不良的影響，降低活塞體2的工作效能，在空氣壓縮機10的活塞體2在停機靜止狀態下，該進氣阻片7之外環分片72係抵觸於前述活塞頭21上的二凸體215、216，如第三至五圖所示，使該進氣阻片7與該活塞頭21的平坦板面5存有一間隙51，且該進氣阻片7的內圓分片73相對該進氣通道23及空氣通道42係保持打開的狀態，藉由活塞體2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，讓每一次的壓縮行程啟始或是靜止狀態再重新啟動時，該活塞體2於上衝行程時不會有阻礙(背壓阻力)，致使活塞體2在汽缸13內進行往復運動時能維持順暢的壓縮效能，較之連接傳統汽車電源使用時，因高電流突波致使保險絲熔斷而停止工作，或者因為純環保電動汽車因其微電腦系統對於電力使用的保護機制而在高電流突波發生時立即截斷電源輸出，以致空氣壓縮機10被停止工作，失去功能等，本發明在平坦板面5上設有凸體的設計確實存有優異的效果。在活塞體2上衝行程如第八圖所示，該進氣阻片7的內圓分片73貼合於前述活塞頭21之平坦板面5上，使進氣阻片7關閉該進氣通道23及空氣通道42；而活塞體2在下衝行程如第七圖所示，該進氣阻片7雖然受到外界空氣的推力而趨於加大張開幅度，但因受限於前述限位卡鈎22所設的橫向柱222，可避免進氣阻片7無限制性的張開而容易導致進氣阻片7之疲乏受損的現象；活塞體2在靜止時候，前述進氣阻片7與前述活塞頭21的頂端平面除了保持打開的狀態，前述進氣阻片7的貫穿孔75則止於前述限位卡鈎22的橫向柱222。本發明之限位卡鈎22所設之豎立柱221係提供進氣阻片7的啟閉張合的路徑，因此可根據空氣壓縮機10功率之大小來調整豎立柱221的長度(或言高度)及橫向柱222的設計而得以調整進氣阻片7的初始高度。因為空氣壓縮機10連接的電源在各種可能的情境下會有高出或低於空氣壓縮機10預設的基準電壓的可能性，而越高的電壓輸入會相對地提高空氣壓縮機10馬達12的轉速，該活塞體2往復循環的頻率也越高，使得由該進氣阻片7下方推開該進氣阻片7的空氣流速加快衝力加大，該進氣阻片7也被掀得越高，折彎角度越大，該進氣阻片7過大的折彎角度及過高的反覆頻率，都將使該進氣阻片7的使用壽命大幅折損，直接減少空氣壓縮機10的使用壽命，而該限位卡鈎22係用於限制該進氣阻片7的振幅高度，以避免該進氣阻片7產生過大的折彎角度及過高的反覆頻率，而能有效地保護該進氣阻片7的使用壽命。Please refer to the first and second figures. The air inlet blocker 7 of the present invention has a non-fully circular annular inner hollow area 71 punched out on its inner periphery, and the air inlet blocker 7 is subdivided into outer The outer ring segment 72 and the inner circle segment 73 form two parts, the outer ring segment 72 and the inner circle segment 73 form a neck segment 74 at the connection point, and the aforementioned air inlet blocking piece 7 is close to the outer ring segment 74 of the neck segment. The segment 72 is provided with a through hole 75 , and the piston head 21 is provided with the limiting hook 22 at a position corresponding to the through hole 75 and engaged with the through hole 75 , and relative to the piston head The two fixing pins 211 and 212 on the piston head 21 are provided with separate round holes 76 and 77 on the air inlet block 7. The round holes 76 and 77 of the air inlet block 7 are used to position the fixing pins 211 of the piston head 21 respectively. , 212, and at the same time, the T-shaped bump 213 of the piston head 21 abuts the outer edge of the outer ring segment 72 of the air inlet blocker 7, and the positioning boss 214 of the T-shaped bump 213 is engaged with the The concave slot 721 on the outer edge of the outer ring segment 72 of the air intake block 7 allows the air intake block 7 to be firmly positioned on the piston head 21, and the positioning protrusion 214 of the T-shaped bump 213 is The structure can be used to identify the installation and positioning direction of the air intake block 7 during assembly operations, because if the air intake block 7 is assembled in reverse, it may have a negative impact on the function of the piston body 2 and reduce the piston body 2 When the piston body 2 of the air compressor 10 is at rest, the outer ring segment 72 of the air inlet blocker 7 is in conflict with the two protrusions 215 and 216 on the piston head 21, as shown in the third As shown in Figure 5, there is a gap 51 between the air inlet blocker 7 and the flat plate surface 5 of the piston head 21, and the inner circular segment 73 of the air inlet blocker 7 is opposite to the air inlet channel 23 and the air channel. 42 is kept in an open state, and the air inlet passage 23 of the piston body 2 is unobstructed to balance the pressure in the cylinder 13 with the surrounding atmosphere, so that the piston can be moved every time the compression stroke starts or is restarted from a standstill. There is no obstruction (back pressure resistance) for the body 2 during the upstroke, so that the piston body 2 can maintain smooth compression performance when it reciprocates in the cylinder 13. Compared with when connected to a traditional car power supply, due to high current surges causing the fuse to blow and stop working, or because the purely environmentally friendly electric vehicle's microcomputer system has a protection mechanism for power use that immediately cuts off the power output when a high current surge occurs, causing the air compressor 10 to stop working and lose its function, etc. The invention's design of providing protrusions on the flat plate surface 5 indeed has excellent effects. During the upper stroke of the piston body 2, as shown in Figure 8, the inner circular segment 73 of the air inlet blocking piece 7 is attached to the flat plate surface 5 of the aforementioned piston head 21, so that the air inlet blocking piece 7 closes the air inlet.

The upright column 221 provided with the limit hook 22 of the present invention provides a path for opening and closing the air inlet blocker 7. Therefore, the length (or height) of the upright column 221 can be adjusted according to the power of the air compressor 10. ) and the design of the transverse pillar 222 to adjust the initial height of the air inlet blocker 7 . Because the power supply connected to the air compressor 10 may be higher or lower than the preset reference voltage of the air compressor 10 in various possible situations, and a higher voltage input will relatively increase the power of the air compressor 10 motor 12 The higher the rotational speed of the piston body 2, the higher the reciprocating frequency of the piston body 2, causing the air flow rate to push away the air intake block 7 from below the air inlet block 7 to accelerate and increase the momentum, and the air inlet block 7 is also lifted The higher it is, the greater the bending angle. The excessively large bending angle and excessive repetition frequency of the air inlet blocker 7 will greatly reduce the service life of the air inlet blocker 7 and directly reduce the use of the air compressor 10 service life, and the limit hook 22 is used to limit the amplitude height of the air inlet blocking piece 7 to prevent the air inlet blocking piece 7 from producing an excessively large bending angle and an excessively high repetition frequency, thereby effectively protecting the air inlet blocking piece 7 The service life of the air intake blocker 7.
