Description
本創作係有關一種氣動擊發裝置，尤指一種控制釋壓通道之啟閉，使流場壓力產生變化，在以氣動方式來擊發子彈；其特別適用於BB槍，但不限定於此。 The present invention relates to a pneumatic firing device, in particular to a control of the opening and closing of the pressure relief passage, which causes a change in the pressure of the flow field, and fires the bullet in a pneumatic manner; it is particularly suitable for the BB gun, but is not limited thereto.
按，壓力空***之BB槍或漆彈槍遊戲，對於生活在都市的民眾而言，除了可遠離塵囂而接近大自然外，更可透過緊張刺激的遊戲過程來放鬆自已，因此，是一種廣受歡迎的運動。 Press, the BB gun or paintball gun game of the pressure air gun, for the people living in the city, in addition to being away from the dust and approaching nature, it can relax itself through the intense game process, so it is a kind of wide Popular sports.
按，BB槍或漆彈槍係藉由壓縮氣體的驅動以擊發子彈，其擊發型態區分為機械式及電子式兩種，其中機械式係以板機控制機械傳動機構，藉以控制槍體內空氣流道的啟閉而將BB彈或漆彈擊發；至於電子式係以扳機控制電子裝置及電磁閥之啟動狀態，在啟動時以電子方式驅動機械傳動機構產生動作以擊發子彈。由於機械式空***使用者手指扣扳機的速度有限，故僅能進行個別擊發，遊戲感較低；反之電子式空***擊發速度快，因此可達到子彈連發的功能。 According to the BB gun or paintball gun, the bullet is fired by the compressed gas, and the impact state is divided into mechanical and electronic. The mechanical type controls the mechanical transmission mechanism by the trigger machine to control the air inside the gun. The BB or paintball is fired by the opening and closing of the flow path; as for the electronic system, the trigger control electronic device and the electromagnetic valve are activated, and the mechanical transmission mechanism is electronically driven to generate an action to fire the bullet at the time of starting. Because the speed of the finger of the mechanical air gun user is limited, only the individual firing can be performed, and the game feeling is low; on the contrary, the electronic air gun has a fast firing speed, so that the bullet bursting function can be achieved.
又按，上揭壓力空***的使用，它的空氣壓力來源為壓縮空氣，經由槍身之壓力調制後，得以對子彈作瞬間高壓擊發，且其擊發方式有：單發及連續擊發兩種。美國專利第5,727,538號、第6,474,326號、第6,516,791號，及第6,532,949號，教示了各種擊發裝置及控制壓縮空氣源的方法，惟在這些專利中，其電子控制裝置與儲存壓縮氣體之驅動方法結合在一起時，會增加機械裝置的固有複雜性，因而增加了成本以及可靠性的問題。 Pressed again, the use of the pressure air gun is exposed. The air pressure source is compressed air. After being modulated by the pressure of the gun body, the bullet can be instantly subjected to high-pressure firing, and the firing method is as follows: single shot and continuous shot. Various firing devices and methods of controlling a source of compressed air are taught in U.S. Patent Nos. 5,727,538, 6,474, 326, 6, 516, 791, and 6, 532, 949. Together, it increases the inherent complexity of the mechanical device, thereby increasing the cost and reliability issues.
為此，本發明人於美國專利US6,601,780號 及pub.NO：US2005/005924A1所揭示之”PAINTGUN WITH PENUMATIC FEEDING AND DISCHARGING PROCES”專利中，係使用一氣動方法來推送漆彈，而具有提高安全性及降低故障率，且使擊發速度增進之優點。惟查，上揭兩件前案中所使用之推送管(Delivery Tube 64)，其前端管體必須套設一復位彈簧(Retum Spring 65)，作為推送管內縮復位之作用力；然因漆彈槍對於擊發速度的要求愈來愈高，其希望每秒鍾20發以上；但是使用之復位彈簧經過上萬次以上之壓縮使用後，會隨著時間而彈性疲乏，以致復位速度會減慢，但因氣壓推動該推送管其前進之速度並沒有改變，而導致往復行程不協調或不完全，如此將影響整體擊發之順暢及速度，故仍有改善空間。 To this end, the inventor of the U.S. Patent No. 6,601,780 And the patent "PAINTGUN WITH PENUMATIC FEEDING AND DISCHARGING PROCES" disclosed in pub. NO: US2005/005924A1, uses a pneumatic method to push paintballs, and has the advantages of improving safety and reducing failure rate, and improving the speed of firing. . However, the lift tube (Delivery Tube 64) used in the two previous cases must be covered with a return spring (Retum Spring 65) as the force for the retraction of the push tube; The requirements for the firing speed of the gun are getting higher and higher, and it is expected to be more than 20 rounds per second. However, after the compression spring used for more than 10,000 times of compression, it will be elastic and fatigued with time, so that the reset speed will be slowed down. However, the speed of the push tube is not changed due to the air pressure, and the reciprocating stroke is uncoordinated or incomplete. This will affect the smoothness and speed of the overall firing, so there is still room for improvement.
本創作人有鑑於此，故如何改進上述問題，即為本創作所欲解決之首要課題。 In view of this, the creator has improved the above-mentioned problems, which is the primary issue that the creative office wants to solve.

本創作之一主要特徵，係該推送管80之第二管體82與該第二軸孔71之間形成一第五間隙(S5)，且該前座70所形成之分氣道72，係與該第五間隙(S5)連通，藉助此一設計可防止前案中僅使用復位彈簧所產生之缺失。至於，本創作所揭示之氣動推送裝置90其作動及使用變化情形，茲配合以下圖式說明如后：首先，如圖3、3A及3B、3C所示，其顯示該電磁閥25之活動柱 塞251關閉之初始狀態，此時該活動柱塞251將釋壓室24之釋壓孔23封閉，本實施例中，由於該小彈簧43會給該活塞體40一向前推力，因此該活塞體40係呈前移狀態，因而與該調整體30之前端面形成一第一間隙(S1)，使得供應之壓縮氣體(A)由第一進氣孔13進入前氣壓室10a後，可較快速的經活動桿60之第二進氣孔62進入後氣壓室10b，當然，壓縮氣體(A)除了可由該該第一間隙(S1)進入後氣壓室10b，另可由該調整體30之前端所設的流通孔35進入後氣壓室10b，也就是說，當該活塞體40後移而頂靠在該調整體30之前端面，而使該第一間隙(S1)沒有了，也不影響該壓縮氣體(A)與後氣壓室10b的流通。至於，該第一間隙(S1)的大小係可用來控制該活塞體40的往復行程，而其可藉由該調整體30可在後座20之第一軸孔21內調整位移進而獲得預定大小的第一間隙(S1)。再者，在本圖示中，該釋壓孔23被該活動柱塞251所封閉，因此該後氣壓室10b的壓縮氣體(A)不再釋出，是以，利用該活塞體前後端之壓力差改變，該活塞體40會向前推移，並使該活動桿60之頂靠體63頂掣在導流通道522之管口，阻斷前氣壓室10a內的壓縮氣體(A)由導流通道522流出(同時產生壓力乘以(＊)該導流通道522面積的前推力)。 A main feature of the present invention is that a fifth gap (S5) is formed between the second tube body 82 of the push tube 80 and the second shaft hole 71, and the air separation channel 72 formed by the front seat 70 is associated with the The fifth gap (S5) is connected, and with this design, the absence of the use of only the return spring in the previous case can be prevented. As for the movement and use change of the pneumatic pushing device 90 disclosed in the present invention, the following description is as follows: First, as shown in Figures 3, 3A and 3B, 3C, the movable column of the electromagnetic valve 25 is displayed. The initial state of the plug 251 is closed. At this time, the movable plunger 251 closes the pressure release hole 23 of the pressure release chamber 24. In this embodiment, since the small spring 43 gives the piston body 40 a forward thrust, the piston body The 40 series is in a forward state, and thus forms a first gap (S1) with the front end surface of the adjusting body 30, so that the supplied compressed gas (A) enters the front air chamber 10a from the first air inlet hole 13 and can be relatively fast. The second air inlet hole 62 of the movable rod 60 enters the rear air pressure chamber 10b. Of course, the compressed gas (A) can be inserted into the rear air pressure chamber 10b by the first gap (S1), and can be set by the front end of the adjusting body 30. The flow hole 35 enters the rear air pressure chamber 10b, that is, when the piston body 40 moves back and abuts against the front end surface of the adjustment body 30, the first gap (S1) is lost, and the compressed gas is not affected. (A) Circulation with the rear air chamber 10b. As for the first gap (S1), the size of the first gap (S1) can be used to control the reciprocating stroke of the piston body 40, and the adjusting body 30 can be adjusted in the first shaft hole 21 of the rear seat 20 to obtain a predetermined size. The first gap (S1). Furthermore, in the present illustration, the pressure relief hole 23 is closed by the movable plunger 251, so that the compressed gas (A) of the rear air pressure chamber 10b is no longer released, so that the front and rear ends of the piston body are utilized. When the pressure difference is changed, the piston body 40 will move forward, and the top body 63 of the movable rod 60 is squatted at the nozzle of the flow guiding passage 522, and the compressed gas (A) in the front air chamber 10a is blocked. The flow passage 522 flows out (while generating a pressure multiplied by (*) the forward thrust of the flow passage 522 area).
接著，如圖4、4A及4B、4C所示，該活動柱塞251受到該扳機203之控制而下移開啟該釋壓孔23，此時該後氣壓室10b內之壓縮氣體(A)就會經由該釋壓通道32流至該釋壓室24，並經由該活動柱塞251之第一排氣孔253流出，並由該電磁閥25之之第二排氣孔254而排除。至此，後氣壓室10b內部已經沒有壓縮氣體(A)，此時前氣壓室10a內的壓縮氣體(A)作用於活塞體40之壓力面積及作用力轉變成大於該小彈簧43的彈力加上(+)壓力乘以(＊)該導流通道522面積的力，使該活動桿60之頂靠體63脫離該導流通道522之管口，形成一第二間隙(S2)，使得該前氣壓室10a內的限量壓縮氣體(A)可由該導流通道522流出，經第一導流孔512及第四間隙(S4)注入周圍之第一分氣道53，使壓縮氣體(A)流 至該推送管80的第二管體82內端面。 Next, as shown in FIGS. 4, 4A and 4B, 4C, the movable plunger 251 is controlled by the trigger 203 to move down to open the pressure release hole 23, and at this time, the compressed gas (A) in the rear pressure chamber 10b is The pressure release passage 32 flows to the pressure release chamber 24, and flows out through the first exhaust hole 253 of the movable plunger 251, and is eliminated by the second exhaust hole 254 of the solenoid valve 25. At this point, there is no compressed gas (A) inside the rear air chamber 10b. At this time, the pressure area and the force acting on the piston body 40 by the compressed gas (A) in the front air chamber 10a are converted to be larger than the elastic force of the small spring 43 plus (+) The pressure is multiplied by (*) the force of the area of the flow guiding passage 522, so that the abutting body 63 of the movable rod 60 is disengaged from the nozzle of the flow guiding passage 522 to form a second gap (S2), so that the front The limited amount of compressed gas (A) in the pressure chamber 10a can flow out through the flow guiding passage 522, and is injected into the surrounding first air separation passage 53 through the first flow guiding hole 512 and the fourth gap (S4) to flow the compressed gas (A). To the inner end surface of the second tube 82 of the push tube 80.
圖5、5A、5B所示係顯示利用該壓縮氣體(A)逐漸使推送管80前移之過程，此時，該推送管80之第一管體81已脫離第一導流孔512，但仍未脫離第二導流孔513，在此同時，推送管80把子彈102由入彈口101往前推向槍管103內。 5, 5A, and 5B show a process of gradually advancing the push tube 80 by using the compressed gas (A). At this time, the first tube 81 of the push tube 80 has been separated from the first guide hole 512, but The second guide hole 513 has not yet been disengaged, and at the same time, the push tube 80 pushes the bullet 102 forward from the entry port 101 into the barrel 103.
緊接著，如圖6、6A、6B所示，當該推送管80之第一管體81脫離該第二導流孔513，此時，該壓縮氣體(A)由分氣道53經該第二導流孔513注入主氣道54(即較小內徑511)，然後再由該推送管80之擊發氣道84以大量噴流將該子彈102擊發出去。 Next, as shown in FIGS. 6, 6A, and 6B, when the first tube 81 of the push tube 80 is separated from the second flow guiding hole 513, at this time, the compressed gas (A) passes through the second air passage 53 through the second The pilot hole 513 is injected into the main air passage 54 (i.e., the smaller inner diameter 511), and then the blower air passage 84 of the push tube 80 is used to strike the bullet 102 in a large number of jets.
接著，如圖7、7A、7B所示，該活動柱塞251上移恢復封閉該釋壓通道32，此時壓力流場產生變化，後氣壓室10b開始有回壓產生，而活塞體40開始向前移；此時，一小部分的壓縮氣體(a)由該第二分氣道72進入該第五間隙(S5)，將推送管80，如圖8、8A、8B所示往內復歸，此時該活塞體40又回復到初始狀態。亦即，活塞體40再次向前推移，並使該活動桿60之頂靠體63重新頂掣在導流通道522之管口，使第二間隙(S2)封閉，阻斷前氣壓室10a內的壓縮氣體(A)由導流通道522流出，但第三間隙(S3)打開，讓剩餘的氣體排出。此時，本創作又回到圖3所示之初始狀態，該前座70內之推送管80，受到第五間隙(S5)內之壓縮氣體(a)的推力，漸漸內移而呈現回復狀態，且第一間隙(S1)打開。 Next, as shown in FIG. 7, 7A, and 7B, the movable plunger 251 is moved up to close the pressure release passage 32, and the pressure flow field changes, and the pressure chamber 10b starts to have a back pressure, and the piston body 40 starts. Moving forward; at this time, a small portion of the compressed gas (a) enters the fifth gap (S5) from the second air separation passage 72, and the push tube 80 is returned inward as shown in Figs. 8, 8A, and 8B. At this time, the piston body 40 is returned to the initial state. That is, the piston body 40 is again pushed forward, and the abutment body 63 of the movable rod 60 is re-engaged at the nozzle of the flow guiding passage 522, so that the second gap (S2) is closed, and the front air chamber 10a is blocked. The compressed gas (A) flows out of the flow guiding passage 522, but the third gap (S3) is opened to allow the remaining gas to be discharged. At this time, the creation returns to the initial state shown in FIG. 3, and the push tube 80 in the front seat 70 receives the thrust of the compressed gas (a) in the fifth gap (S5), and gradually moves backward to assume a return state. And the first gap (S1) is opened.
藉由上揭技術手段，本創作氣動擊發裝置90，以氣體流場之壓力變化，先以小氣流推動推送管80，使子彈102先前送，再以大量噴射氣流來推動發射，此種兩階段氣體推送進給方式，所獲致之功效增進如后： By means of the above-mentioned technical means, the pneumatic firing device 90 of the present invention firstly pushes the push tube 80 with a small air flow by the pressure change of the gas flow field, so that the bullet 102 is previously sent, and then the jet is pushed by a large amount of jet airflow. The gas push feed mode is improved as follows:
一、本創作以電磁閥25控制釋壓通道32之啟閉，進而改變該活塞體之前、後氣壓室10a、10b的壓力差，先以壓縮氣體(A)由該導流體50之第一導流孔512進入 該第一分氣道53，使該推送管80前移，將置於前方之一子彈102往前送，壓縮氣體(A)再由該第二導流孔513注入該主氣道54後，由該推送管80之擊發氣道84以大量噴流將該子彈102擊發出去，其具有氣流進給順暢，得以增進擊發速度。 1. The creation uses the solenoid valve 25 to control the opening and closing of the pressure relief passage 32, thereby changing the pressure difference between the front and rear pressure chambers 10a, 10b of the piston body, firstly using the compressed gas (A) from the first guide of the fluid guide 50 Flow hole 512 enters The first air separation duct 53 advances the push tube 80, and forwards one of the bullets 102 forward, and the compressed gas (A) is injected into the main air passage 54 by the second air guiding hole 513. The firing air passage 84 of the push tube 80 strikes the bullet 102 with a large number of jets, which has a smooth airflow feed to increase the firing speed.
二、本創作之結構單純，組裝容易，相對地可降低其故障率，且整個氣動擊發裝置90得以模組化，因此可適用不同樣式之壓力空***，擴增使用範圍。 Second, the structure of the creation is simple, the assembly is easy, the failure rate can be relatively reduced, and the entire pneumatic firing device 90 can be modularized, so that different styles of pressure air guns can be applied to expand the range of use.
三、更重要的是，當主氣道54使用氣流時，第一分氣道53係呈匯流狀注入主氣道54，因此，大量的氣流完全集中而沒有分散，並呈順暢的軸向噴射來推子彈，使得本創作在壓縮氣體(A)之壓力在較低壓時，即可順利將子彈發射至預定距離，因而可降低壓縮氣體(A)之壓力，不僅安全性可提升，且成本亦可降低。 Third, more importantly, when the main air passage 54 uses airflow, the first air separation passage 53 is injected into the main air passage 54 in a confluent manner. Therefore, a large amount of airflow is completely concentrated without being dispersed, and a smooth axial injection is performed to push the bullet. Therefore, when the pressure of the compressed gas (A) is at a lower pressure, the bullet can be smoothly emitted to a predetermined distance, thereby reducing the pressure of the compressed gas (A), which not only improves safety but also reduces cost. .
四、本創作利用該調整體30可在後座20之第一軸孔21內調整位移，進而可控制活塞體40的往復行程，進而具有調整擊發速度之功效者。 4. The present invention utilizes the adjusting body 30 to adjust the displacement in the first shaft hole 21 of the rear seat 20, thereby controlling the reciprocating stroke of the piston body 40, and further having the effect of adjusting the firing speed.
五、本創作利用前座70所形成之第二分氣道72，以一小部分的壓縮氣體(a)由該第二分氣道72進入該第五間隙(S5)，以第五間隙(S5)內之壓縮氣體(a)的推力，漸漸使推送管80內移而呈現回復狀態，藉助此一設計可防止前案中僅使用復位彈簧所產生之缺失。 5. The second air passage 72 formed by the front seat 70 is used to enter the fifth gap (S5) from the second air passage 72 with a small portion of the compressed gas (a), in the fifth gap (S5). The thrust of the compressed gas (a) gradually causes the push tube 80 to move inward to assume a return state, and with this design, the absence of the use of only the return spring in the previous case can be prevented.
綜上所述，本創作所揭示之構造，為昔所無，且確能達到功效之增進，並具可供產業利用性，完全符合新型專利要件，祈請 鈞局核賜專利，以勵創新，無任德感。 In summary, the structure revealed by this creation is unprecedented, and it can achieve the improvement of efficacy, and it can be used for industrial utilization. It fully complies with the new patent requirements, and invites the bureau to grant patents to encourage innovation. There is no sense of morality.
