具体实施方式 DETAILED DESCRIPTION
现在转到附图，在所有图中以类似的参考字符表示类似或相应的部件。 Turning now to the drawings, in all figures in which like reference characters indicate like or corresponding parts. 根据本发明的扳机致动泵喷雾器在图中总体上以10表示，并包括一个例如在图5中所示的泵体11，而泵体又具有一个泵缸12，泵缸中安装着一个能够随着扳机杆14的操作而往复运动的泵活塞13，扳机杆安装在泵体上并与活塞外端支承咬合。 Actuated pump sprayer generally in the drawing in accordance with the present invention to trigger at 10, and comprises a pump body 11 in the example shown in Figure 5, and the pump body and having a pump cylinder 12, a pump cylinder can be mounted 13, the pump piston with the trigger lever 14 and trigger lever mounted on the reciprocating motion of the pump piston and engages the outer end of the support. 活塞被一个活塞复位弹簧(未示出)沿着从活塞孔向外的方向推压，从而在每次按压扳机杆后将活塞从活塞孔向外弹性推动，如这种类型的任何一种传统扳机喷雾器那样。 The piston is a piston return spring (not shown) in a direction outwardly from the pressing piston bore, so that each time the trigger lever is pressed after pushing the piston outwardly from the piston bore elastic, such as any conventional type of trigger sprayer that. 作为示例，弹簧推压活塞的细节公开于本发明人共同拥有的美国专利6,095,377中，该专利因此而特别整体结合在此作为参考。 As an example, a spring urging the piston disclosed in detail in U.S. Patent 6,095,377 commonly owned the present inventor, which patent is therefore specifically incorporated herein by reference in entirety.
泵体具有一个终止于排出口15(图2)的排出通道(未示出)，排出口形成在一个安装在泵体喷嘴端(未示出)的手工旋转喷嘴盖16中。 Terminating in the pump body having a discharge port 15 (FIG. 2) of the discharge passage (not shown), a discharge port formed in the pump nozzle mounted on the end (not shown) of the manual rotation of the nozzle cap 16. 泵体具有一个连接在其上的大致圆柱形封口盖17，用以将扳机喷雾器安装在容器C的颈部上，容器中容纳着随着扳机的操作而散布的制品。 The pump body having a substantially cylindrical shape at a connection 17 on which the sealing cap for mounting the trigger sprayer on the container neck C, contained in the container with the operation of the trigger with the spread of products. 如图5中更清楚地显示，封口盖具有一个上壁，其确定出一个指向内侧的环形凸缘18，用以覆盖泵体管状部分21的下端处的一个指向外侧的环形凸缘19。 Figure 5 more clearly show, the sealing cover having an upper wall, which defines a point of the inner circular flange 18, to cover the lower end of a tubular portion 21 of the pump body at a point outside of the annular flange 19. 封口盖上可以带有整体式螺纹，用于咬合容器颈部上的外螺纹(未示出)。 Sealing can cover with integral threads for engaging external threads on the neck of the container (not shown). 一个汲取管22(图2)从泵体的进入通道(未示出)悬挂伸入容器中，用于随着活塞的每次抽吸行程而将液体传输到泵室中，这与本技术领域中众所周知的方式一样。 A dip tube 22 (FIG. 2) from the pump housing inlet passage (not shown) extending into the suspension vessel, for with each suction stroke of the piston and the liquid is transferred to the pump chamber, which in the art well known in the same manner.
扳机喷雾器还具有一个护罩23，其覆盖着泵体，并且以本技术领域中众所周知的方式通过组装而连接在泵体上。 Trigger sprayer further includes a shroud 23 which covers the pump body, and is well known in the art by way of the connection assembly of the pump body. 护罩具有一对相反的侧壁24、25，它们终止于一个毗邻喷嘴盖16的前端，并具有一个与封口盖17并置的下边缘26。 The shroud having a pair of opposite side walls 24 and 25, which terminates in a distal end 16 adjacent the nozzle cover, and having a cap 17 and the sealing edge 26 juxtaposed.
护罩具有一个顶壁27，其可以是平坦的，以及一个驼背形后端28，其与一个从封口盖17向后延伸的底壁29相交，并且如图3中更清楚地显示，可以是略微中凸的。 Shroud having a top wall 27, which may be flat, and a hump-shaped rear end 28, with a sealed cover 17 extends rearwardly from the bottom wall 29 intersect, and in Figure 3 show more clearly, may be slightly convex. 特别是根据本发明，护罩具有由凸块确定出并与相应侧壁24、25形成一体的侧鞍31、32。 In particular, according to the present invention, the cover having a projection determined with the respective side walls 24, 25 formed integrally with the side saddle 31. 特别如图1所示，侧鞍在护罩的前边缘33、34与护罩的后终止端35之间纵向连续延伸。 1 in particular, the saddle in front shroud side edges 33, 34 of the termination of the shroud extending continuously longitudinally between the ends 35. 同时，每个侧鞍分别从封口盖17的圆形侧壁侧向向外伸出一个距离A，如图3所示。 Meanwhile, each of the side covers, respectively, from the saddle seal 17 is circular laterally outwardly projecting side wall a distance A, as shown in FIG. 侧鞍的底表面36、37确定出支靠在操作者的大拇指和食指的顶部的人机工程型支座，如后文中更完整的描述。 The bottom surface of the side saddle 36,37 determine resting on top of the operator's thumb and forefinger Ergonomic seat, as hereinafter more fully described. 底表面36、37与护罩的底壁29光滑地汇合，以使它们基本上共面(见图1和3)。 36, 37 and the bottom surface of the bottom wall of the shroud 29 smoothly converge so that they are substantially coplanar (see FIG. 1 and 3).
特别如图2所示，构成侧鞍的凸块是由护罩的弯曲部分确定出来的，并且与主要在图5中示出的护罩剩余部分的厚度相等。 In particular as shown in Figure 2, constituting the side saddle bumps is determined by the bent portion out of the shroud, and the thickness of the remaining portion of the main shroud 5 shown in FIG equal.
护罩具有一个收缩喉部38，其形成在护罩的侧鞍31、32与下边缘26之间。 Shroud having a retracted throat 38 formed in the side of the saddle 31, 32 between the shroud and the lower edge 26. 收缩部分是由侧壁24、25的向内弯曲段39、41确定出来的(见图2和3)。 Contraction portions are bent inwardly by the side wall sections 24, 25 39, 41 out of the determined (see Figures 2 and 3). 收缩部分还在毗邻底壁29的护罩后端处由向内弯曲段42(图1)确定。 Also constricted portion adjacent to the bottom wall 29 of the shroud at the rear end by an inwardly bent section 42 (FIG. 1) is determined. 如图3所示，每个向内弯曲段39、41分别从封口盖的圆形侧壁向内间隔一个距离B。 3, each of the inwardly curved segment 39, 41, respectively, from the circular side wall sealed cover spaced inwardly a distance B. 此外，如图1所示，向内弯曲段42从封口盖的圆形侧壁向内间隔一个距离D。 In addition, 1, inwardly curved section 42 from the circular sidewall of a sealed cover spaced inwardly from the D.
参看图3，可以看到，每个侧鞍的侧向延伸边界与喷雾器的纵向中心线之间的距离为E，距离E等于A+G，其中G是封口盖的半径。 Referring to Figure 3, can be seen, each side of the saddle extends laterally from the longitudinal centerline between the boundary and the sprayer is E, the distance E is equal to A + G, where G is the radius of the sealing cap. 更重要的是，喷雾器中心线与每个向内弯曲段39、41之间的距离F小于距离G。 More importantly, the sprayer centerline and inwardly from each segment 39, 41 is less than the distance between the F G.
本发明除了能够提供改进的人机工程学效果以外，还可以在改进人机工程学效果的同时使喷雾器的尺寸最小化。 In addition to the present invention to provide improved ergonomics, it also allows to minimize the size sprayer while improving the ergonomics. 因此，可以使E最小化，同时维持由每个距离H提供的有效支座，该距离H等于E减去F。 Thus, E can be minimized, while maintaining effective distance provided by each holder H, the distance H is equal to minus E F. 通过设置向内弯曲段39、41，可以容易地获得以距离H度量的适宜侧向支座。 By setting the inwardly curved sections 39, 41, can be easily obtained with a suitable measure of lateral distance H abutment.
在使用中，操作者抓住喷射器组件，即以手掌大致围绕着封口盖和瓶颈，以使大拇指与食指之间的手掌组织位于底壁29的底侧。 In use, the operator grasps the injector assembly, i.e., the palm and a substantially sealed cover around the bottleneck, so that the palm between the thumb and index finger tissue located on the bottom wall 29 of the bottom side. 大拇指还延伸到侧鞍31的底表面36的底侧，而食指延伸到侧鞍32的底表面37的底侧。 Thumb also extends to the side surface of the bottom side of the saddle 36 of the bottom 31, while the index finger extends to the bottom side of the saddle surface 32 of the bottom side 37. 大拇指、食指和手掌组织因此而抓住由向内弯曲段39、41、42组成的收缩部分38。 Thumb, index finger and palm organization therefore caught by an inwardly curved sections 39,41,42 composed constricted portion 38. 操作者可以简单和方便地利用食指或食指与中指控制扳机杆，以拉动扳机而操作泵。 The operator can simply and easily use the index finger and the index finger or middle finger to control the trigger lever to pull the trigger and operate the pump. 在泵喷雾器被如前所述保持着时，附着了喷雾器的液体容器向下悬垂，其重量被操作者手部方便地承载着，而不会在喷雾操作中带来疲劳和不适。 As mentioned above the pump sprayer is maintained when the liquid container is attached a downwardly depending sprayer, its weight by the operator easily carries the hand, without incurring the fatigue and discomfort in the spraying operation. 根据本发明的侧鞍为喷雾器组件提供了简单且高效的人机工程型侧向支座，喷雾器组件还可以具有一个底壁29，其通常支靠在操作者手部组织上。 According to the present invention is to provide side saddle sprayer assembly for a simple and efficient Ergonomic lateral support base, the nebulizer assembly may also have a bottom wall 29, which usually rests on the operator hand tissue.
由于侧鞍和收缩喉部是在模塑成型过程中由简单的弯曲部分构成的，而且由于整个护罩具有均匀的厚度，因此护罩可以容易地由塑料成型出来，而成型设备具有最小的变化。 Since the side saddle and contraction in the throat by a simple molding process curved parts, and because the shield has a uniform thickness throughout, so the shield can be easily molded out of plastic, and the molding equipment have minimal changes .
显然，在上述示例的指导下可以对本发明作出许多其他改型和变化。 Obviously, under the guidance of the above example can be made of many other modifications and variations of the present invention. 因此可以理解，本发明可以在附属发明保护范围而非特别描述的范围内实施。 Therefore to be understood, may be practiced within the scope of the invention instead by scope of the appended present invention is specifically described.
