Description
本創作涉及一種燃料添加劑的添加裝置，尤其涉及一種汽油精泵，屬於機械動力裝置的燃料添加裝置領域。The present invention relates to a fuel additive adding device, and more particularly to a gasoline pump, which belongs to the field of fuel adding devices of mechanical power devices.
汽車作為交通工具的普及，已經進入到越來越多普通人的日常生活中。但是，大多數人只是使用汽車，希望汽車保養能傻瓜化，這就對汽車的經濟節油性、排放標準和免維護性等方面提出了更高要求。研究顯示，在汽車燃油中(家用轎車主要是汽油)加入適當的添加劑，可以有效地改善燃油的性能，並使燃油的燃燒速度提高到適當的範圍。因為燃油添加劑加進汽油中之後，能在進氣閥的進氣系統表面形成一層保護層，防止發動機內部尤其是進氣系統內產生大量的沉積物，使汽車的發動機在整個使用過程中保持清潔，而且，使用添加了清淨劑的汽油對車主來說還能夠實現省油之目的。The popularity of automobiles as vehicles has entered the daily life of more and more ordinary people. However, most people just use cars and hope that car maintenance can be fooled, which puts higher demands on the car's economical fuel economy, emission standards and maintenance-free. Studies have shown that adding appropriate additives to automotive fuels (mainly for petrol) can effectively improve fuel performance and increase fuel burn rate to an appropriate range. Because the fuel additive is added to the gasoline, a protective layer can be formed on the surface of the intake valve of the intake valve to prevent a large amount of deposits inside the engine, especially in the intake system, so that the engine of the car is kept clean throughout use. Moreover, the use of detergent with added detergent can also achieve fuel economy for the owner.
燃料添加劑通常通過汽油精泵而添加到發動機中，例如中國創作專利申請CN102748165 A公開了一種汽油精泵，該泵包括殼套、端蓋以及吸管；泵組件包括有套圈、內插杆、彈簧和按鈕開關，吸管連接在套圈的底部，內插杆插設於套圈中；套圈具有沿橫截面方向設置的隔片，隔片上開設有軸向貫通的通道，內插杆的底端形狀與通道相適配且能封堵在該通道上。The fuel additive is usually added to the engine by a gasoline pump. For example, the Chinese patent application CN102748165 A discloses a gasoline pump including a casing, an end cover and a straw; the pump assembly includes a ferrule, an insert rod, and a spring. And a button switch, the straw is connected at the bottom of the ferrule, and the insertion rod is inserted in the ferrule; the ferrule has a spacer disposed along the cross-sectional direction, the diaphragm is provided with an axial through passage, and the bottom end of the insertion rod The shape is adapted to the channel and can be blocked on the channel.
該創作採用水平推動方式操作，可有效地控制套圈通道的開口大小，易施力。但是也存在一定的缺陷，例如：當需 要加注部分燃料添加劑時，需要即時通過第一隔片關閉內孔的出液通道，而由於第一隔片距離出液口位置較遠，將汽油精泵取出時，出液口與第一隔片之間的內孔中會存留有燃料添加劑。這些缺點不但會導致添加的燃料添加劑劑量不準確，而且還造成燃料添加劑的浪費。尤其是當大規模使用時，可嚴重地增大燃料添加劑的總體消耗，提高了日常使用成本。The creation is operated in a horizontal push mode, which can effectively control the opening size of the ferrule passage and is easy to apply force. But there are also certain flaws, such as: when needed When filling a part of the fuel additive, it is necessary to immediately close the liquid outlet passage of the inner hole through the first spacer, and since the first spacer is far from the liquid outlet, when the gasoline pump is taken out, the liquid outlet and the first outlet Fuel additives are retained in the inner bore between the septa. These shortcomings not only result in inaccurate doses of added fuel additives, but also waste fuel additives. Especially when used on a large scale, the overall consumption of fuel additives can be seriously increased, and the daily use cost is increased.
因此，對於開發一種新型的汽油精泵，不但具有迫切的研究價值，也具有良好的經濟效益和工業應用潛力，這正是本創作得以完成的動力所在和基礎。Therefore, the development of a new type of gasoline pump is not only of urgent research value, but also has good economic benefits and industrial application potential.

由於環套上設有環形凸緣，對汽油箱的注油口起到了密封作用，汽油精泵與汽油箱連接加液過程當中，揮發性氣體不會散發到大氣中，做到了兩個容器之間與外界大氣全密封的狀態下進行氣液交換(加液瓶的液體到油箱裡，油箱的氣體到加液瓶裡，汽油柴油都有揮發性氣體的，添加劑可能也有揮發性氣體)，減少了大氣污染，保護了環境。Due to the annular flange on the ring sleeve, the oil filling port of the fuel tank is sealed. During the process of adding the gasoline pump to the fuel tank, the volatile gas is not released into the atmosphere, and the two containers are Gas-liquid exchange with the outside atmosphere (the liquid in the liquid bottle is added to the tank, the gas in the tank is in the liquid bottle, the gasoline and diesel have volatile gases, and the additive may also have volatile gas), which is reduced. Air pollution protects the environment.
由於密封圈與控制套筒過盈配合連接，杜絕了揮發性氣體外溢，進一步保證了汽油精的加注順暢，並且減少了大氣污染，保護了環境。Due to the interference fit between the sealing ring and the control sleeve, the volatile gas overflow is eliminated, which further ensures the smooth filling of the gasoline, reduces the air pollution and protects the environment.

A torsion spring 65 is disposed between the torsion spring upper seat 64 and the torsion spring lower seat 63. They are respectively disposed on the two switch plates 62. Two limit plates are further disposed on the ferrule 3 between the two side plates 32. The end of the torsion spring 65 is located between the limit plate and the switch plate 62, so that the switch plate 62 More stable when used in a slot. The design is cleverly designed and compact, which increases the performance of the push button switch 6.
殼套1上位於汽油箱連接腔一端設有防盜端蓋8，防盜端蓋8作為市場上常用的一種產品，其結構以及與殼套1的配合使用都是本領域技術人員所熟知的，在此不再贅述。汽油精泵還 包括一保險栓9，保險栓9包括連接在一起的鎖套、鎖杆和鎖頭，鎖套套設於防盜端蓋8上，鎖套夾壓於按鈕61與殼套1之間，鎖杆連接鎖套和鎖頭。The shell 1 is provided with a burglar end cover 8 at one end of the connecting chamber of the fuel tank. The burglar end cover 8 is a commonly used product on the market, and its structure and cooperation with the casing 1 are well known to those skilled in the art. This will not be repeated here. Gasoline pump The utility model comprises a safety pin 9 which comprises a locking sleeve, a locking rod and a locking head which are connected together. The locking sleeve is sleeved on the anti-theft end cover 8, and the locking sleeve is clamped between the button 61 and the casing 1, and the locking rod is connected. Lock sleeve and lock.
為了保證加注順暢，防止揮發性氣體外溢，環套11上設有一與汽油箱的注油口相適配的環形凸緣12，環形凸緣12位於汽油箱連接腔內；進一步地，環套11上套設有一密封圈13，密封圈13位於環套11與控制套筒5之間且密封圈13過盈連接於控制套筒5上。In order to ensure a smooth filling and prevent the outflow of volatile gas, the ring sleeve 11 is provided with an annular flange 12 adapted to the oil filling port of the gasoline tank, and the annular flange 12 is located in the connecting chamber of the fuel tank; further, the ring sleeve 11 The upper sleeve is provided with a sealing ring 13 between the ring sleeve 11 and the control sleeve 5 and the sealing ring 13 is interference-connected to the control sleeve 5.
進一步結合圖7，使用時，首先打開防盜端蓋8，拔出保險栓9，汽油精瓶通過汽油精瓶連接螺紋安裝在汽油精瓶連接部31上，將汽油精泵整體倒置，連接到汽油箱的加液接口上，按動按鈕開關6，控制套筒5打開液體流通通道44和回氣通道43，汽油精依次通過汽油精瓶連接部31、回氣座4的固定端41、回氣座4的支撐端42、控制套筒5端部的出液口57，流入到汽油箱內，為了保證汽油精瓶內的壓力平衡，氣體經過控制套筒5端部的回氣口54進入回氣座4內的回氣通道43，由回氣管2進入汽油精瓶，保證了汽油精的順暢加注。當加注結束時，鬆開按鈕開關6，第一凸起52和第二凸起53直接關閉回氣通道43和液體流通通道44的端部，液體流通通道44內的汽油精仍然會回流到汽油精瓶內，不會揮發掉，也就克服了浪費現象。Further, in combination with FIG. 7, when in use, the anti-theft end cap 8 is first opened, and the safety pin 9 is pulled out. The gasoline refining bottle is installed on the gasoline refining bottle connecting portion 31 through the gasoline refining bottle connecting thread, and the gasoline refining pump is inverted up to be connected to the gasoline. On the liquid adding interface of the box, the push button switch 6 is pressed, and the control sleeve 5 opens the liquid circulation passage 44 and the return air passage 43. The gasoline essence passes through the gasoline fine bottle connecting portion 31, the fixed end 41 of the return air seat 4, and the return air. The support end 42 of the seat 4 and the liquid outlet 57 of the end of the control sleeve 5 flow into the gasoline tank. In order to ensure the pressure balance in the gasoline refinery bottle, the gas enters the return air through the air return port 54 at the end of the control sleeve 5. The return air passage 43 in the seat 4 is entered into the petrol bottle by the return air pipe 2, thereby ensuring a smooth filling of the gasoline. When the filling is completed, the push button switch 6 is released, and the first projection 52 and the second projection 53 directly close the ends of the return air passage 43 and the liquid circulation passage 44, and the gasoline concentrate in the liquid circulation passage 44 still returns to the end. In the petrol bottle, it will not evaporate, which will overcome the waste phenomenon.
