请参阅图 4所示， 经上述元件的组合， 将本实用新型结构卡合于充气罐 1 的顶部， 一般而言， 充气罐 1的喷嘴柱 11下沉就得喷出罐内的气体， 通常气管 4会与导流滑块 3—起连动， 导流滑块 3能够在帽体 2的座体 21上的 U形滑槽 211 内上下滑移， 需要注意的是， 气管 4与充气罐 1所成角度与导流滑块 3的内部弯 状流道 31的角度成预设配合角度； 例如， 当气管 4与充气罐 1所成角度为仰角 时， 导流滑块 3的内部弯状流道 31的角度也与之配合成仰角； 反之亦然， 总之 两个角度要成预设的配合角度。 在自然状态下， 充气罐 1的喷嘴柱 11是关闭， 此时的恒开装置 5是躺平状且导流滑块 3处在最高点。 Referring to FIG. 4, the structure of the present invention is engaged with the top of the aeration tank 1 through the combination of the above components. Generally, the nozzle column 11 of the aeration tank 1 sinks to eject the gas in the tank, usually The gas pipe 4 will be interlocked with the flow guiding slider 3, and the flow guiding slider 3 can slide down in the U-shaped sliding groove 211 on the seat body 21 of the cap body 2. It should be noted that the gas pipe 4 and the gas canister 1 is formed at an angle with a predetermined angle of engagement with the inner curved flow path 31 of the flow guiding slider 3; for example, when the angle between the air tube 4 and the aeration tank 1 is an elevation angle, the inner curved shape of the flow guiding slider 3 The angle of the flow path 31 is also matched with the elevation angle; vice versa, in short, the two angles are to be preset engagement angles. In the natural state, the nozzle column 11 of the aeration tank 1 is closed, At this time, the constant opening device 5 is lying flat and the flow guiding slider 3 is at the highest point.
图 5为图 4中 A-A向横剖面的俯视图； 图 6为本实用新型实施例的恒开 装置打开充气罐的剖面示意图； 请参阅图 3、 图 5及图 6所示， 帽体 2的座 体 21上的 U形滑槽 211内再凹设一扣合槽 212专供恒开装置 5的转轴 51扣 合， 如此恒开装置 5得因使用人扳动恒开装置 5的把柄 52, 将恒开装置 5整 个由躺平状旋转成竖直状， 在其旋转的过程中， 恒开装置 5的顶抵部 53便压 氐导流滑块 3而将导流滑块 3向下滑移， 又该导流滑块 3流道 31的另一端 312将压抵充气罐 1的喷嘴柱 11 下沉， 导致充气罐 1 内的气体将随流道 31 及气管 4而喷出于外， 以达待充气物充气的目的； 若待充气物充完气后， 将 恒开装置 5整个由竖直状旋转恢复成躺平状， 则本实用新型结构又回复自然 状态， 即充气罐的喷嘴柱呈关闭状态， 然后再盖入上盖 6 , 以便下次再使用。  Figure 5 is a plan view of the AA cross section of Figure 4; Figure 6 is a cross-sectional view of the constant opening device of the embodiment of the present invention opening the aeration tank; see Figure 3, Figure 5 and Figure 6, the seat of the cap 2 A locking groove 212 is further recessed in the U-shaped sliding groove 211 of the body 21 for fastening the rotating shaft 51 of the constant opening device 5, so that the constant opening device 5 is caused by the user pulling the handle 52 of the constant opening device 5, The constant opening device 5 is entirely rotated from the lying flat to the vertical shape. During the rotation thereof, the top abutting portion 53 of the constant opening device 5 presses the guiding slider 3 to slide the guiding slider 3 downward. And the other end 312 of the flow guiding block 3 of the flow guiding block 3 sinks the nozzle column 11 pressed against the aeration tank 1 , so that the gas in the aeration tank 1 will be sprayed out along with the flow path 31 and the gas pipe 4 to The purpose of inflating the inflated product; if the inflating device is fully charged, the entire constant opening device 5 is restored from the vertical rotation to the lying flat shape, and the structure of the utility model returns to the natural state, that is, the nozzle column of the aeration tank It is closed and then covered in the upper cover 6 for reuse next time.
