Description
本發明係與充氣設備有關,更詳而言之係指一種打氣筒及其儲氣筒、切換閥與切換閥心。 The present invention relates to an inflatable device, and more particularly to an inflator and its air reservoir, a switching valve and a switching valve core.
按,習知之打氣筒,尤指人力作動之打氣筒,其主要係用以對外物(如輪胎、球體進行充氣)。 According to the conventional pump, especially the man-made pump, which is mainly used for external objects (such as tires and spheres).
惟,目前常見以人力作動之打氣筒主要分為二種,其一種為直接供氣型式,即在使用者作動時,直接將氣體注入於外物內,另一種則為儲氣型式,即使用者在作動時係將氣體先行注入而儲存在儲氣筒內,待欲充氣時再由該儲氣筒對外物進行充氣。 However, at present, there are two main types of pumpes that are manually operated by human beings. One of them is a direct air supply type, that is, when the user operates, the gas is directly injected into the foreign object, and the other is the gas storage type, that is, the use. When the actuator is actuated, the gas is injected first and stored in the air reservoir, and when the air is to be inflated, the external air is inflated by the air reservoir.
然而,上述二種打氣筒,無論係直接供氣型式或儲氣型式,皆有其優點,如直接供氣型式之打氣筒,適用於需要氣壓較低之外物(如低壓輪胎),而儲氣型式之打氣筒,則適用於需要氣壓較高之外物(如高壓輪胎)。但,若購置二種不同型式之打氣筒,則會有花費支出過多,且在使用上不夠方便及收納時佔用空間之問題。 However, the above two types of inflators have advantages such as a direct air supply type or a gas storage type, such as a direct air supply type air pump, which is suitable for a low pressure external object (such as a low pressure tire), and is stored. Air-type pumps are suitable for applications requiring high air pressure (such as high-pressure tires). However, if you purchase two different types of inflators, you will have to spend too much, and it is not convenient enough to use and take up space when you store.

是以,上述即為本發明一較佳實施例所提供之打氣筒100各部構件及其組裝方式之介紹,接著再將其使用特點介紹如下:首先,當使用者欲由打氣筒主體10對該儲氣筒20進行儲氣時,使用者先將該切換桿226進行切換,使由該凹部293抵接於該切換閥心222上(如第二圖所示),使此時該閥心孔201與該筒體接孔204保持暢通,如此一來,使用者在控制該活塞桿組12作動時,該筒身112內之氣體會被活塞121所擠壓而經過該注氣底塞115,並再經由該逆止閥13、輸氣管14而送入於該輸入嘴151內,使送入於該輸入嘴151內之氣體便能經由至少一輸出嘴153輸入至該切換閥22之閥心孔201內,以讓氣體經由該筒體接孔204而進入於該筒體21內(如第二圖所示),以達到進行儲氣之功效,且由於進入於該輸入孔252內之氣體,在自該輸出孔258送出後,會將該第二o形環27及第三o形環28往二 第二切槽257另一方向推,使得由該第二o形環27擋住於該輸出孔258與該輸出管接孔206間,該第三o形環28擋住於該桿孔202,而使氣體此時無法自該輸出管24所送出或由該桿孔202洩出,以維儲氣時之順暢性及氣密性,而該儲氣室211之氣壓,則先經由該閥心孔201,再由該氣壓錶接孔205而顯示於該氣壓錶23。 Therefore, the above is a description of the components of the pump 100 and the manner of assembly thereof provided by a preferred embodiment of the present invention, and then the features of use thereof are as follows: First, when the user wants to use the pump body 10 When the air reservoir 20 performs air storage, the user first switches the switching lever 226 so that the recess 293 abuts against the switching valve core 222 (as shown in the second figure), so that the valve core hole 201 is at this time. The cylinder hole 204 is kept open, so that when the user controls the piston rod group 12 to operate, the gas in the barrel 112 is pressed by the piston 121 and passes through the gas injection bottom plug 115, and Then, the check valve 13 and the air supply pipe 14 are sent into the input nozzle 151, so that the gas fed into the input nozzle 151 can be input to the valve center hole of the switching valve 22 via the at least one output nozzle 153. 201, in order to allow gas to enter the barrel 21 through the barrel receiving hole 204 (as shown in the second figure), in order to achieve the effect of gas storage, and due to the gas entering the input hole 252, After being sent out from the output hole 258, the second o-ring 27 and the third o-ring 28 are moved to the second The second slot 257 is pushed in the other direction so as to be blocked by the second o-ring 27 between the output hole 258 and the output tube receiving hole 206, and the third o-ring 28 blocks the rod hole 202, so that At this time, the gas cannot be sent out from the output pipe 24 or discharged from the rod hole 202, so as to maintain the smoothness and airtightness of the gas storage, and the air pressure of the gas storage chamber 211 passes through the valve core hole 201 first. And the barometer 205 is displayed on the barometer 23 again.
接著,當使用者欲由該儲氣筒20對外物進行充氣時,先將該切換桿226之凸部294切換至與該切換閥心222抵接,以推動該切換閥心222位移,並使其一第二切槽257與該輸出管接孔206導通(如第三圖所示)。如此一來,該筒體21內之氣體便能經由該筒體接嘴212、筒體接孔204而將該第二o形環27往另一第二切槽257之方向推移,使氣體得以藉由此一第二切槽257而進入於其一輸出孔258後,再由另一輸出孔258及另一第二切槽257所送出,並再進入於該輸出管接孔206內,以送出至該輸出管24外,藉以達到由該儲氣筒20對輪胎(圖未示)進行充氣之功效,而該輪胎氣壓,則藉由該二第一切槽256之設置,讓氣體將該第一o形環26往該二第一切槽256方向推,經由該閥心孔201,再由該氣壓錶接孔205而顯示於該氣壓錶23。 Then, when the user wants to inflate the foreign object from the air reservoir 20, the convex portion 294 of the switching lever 226 is first switched to abut against the switching valve core 222 to push the switching valve core 222 to be displaced and A second slot 257 is electrically connected to the output tube socket 206 (as shown in the third figure). In this way, the gas in the cylinder 21 can pass the second o-ring 27 to the other second slot 257 via the barrel nozzle 212 and the barrel receiving hole 204, so that the gas can be After entering the output hole 258 by the second slot 257, the other output hole 258 and the other second slot 257 are sent out, and then enter the output tube hole 206 to And sent to the outside of the output tube 24, thereby achieving the effect of inflating the tire (not shown) by the air reservoir 20, and the tire air pressure is set by the two first slots 256 to allow the gas to be An o-ring 26 is pushed in the direction of the two first slits 256, and is displayed on the barometer 23 via the valve core hole 201 and the barometer hole 205.
再者,在由該儲氣筒20對外物進行充氣時,若儲氣筒20內之氣體不足時,亦可由該打氣筒主體10將氣體送入切換閥22內,以再自該輸出管24送出(如第四圖所示),以進行補氣之功效。 Further, when the gas is inflated by the air reservoir 20, if the gas in the air reservoir 20 is insufficient, the gas can be sent from the pump body 10 to the switching valve 22 to be sent out from the output tube 24 ( As shown in the fourth figure, to make the effect of qi.
