Abstract
The utility model relates to a knapsack sprayer. The utility model is composed of a liquid storing cylinder, a rotating and pressing device, and a spraying component, wherein, the rotating and pressing device is communicated with the rotating and pressing device; the liquid storing cylinder comprises a cylinder body, an upper closed cover, a lower closed cover, and the periphery of the upper closed cover and the periphery of the lower closed cover are provided with convex edges; the upper closed cover and the lower closed cover are close assembled as a whole through the convex edge, and a liquid inlet is arranged on the upper closed cover. The utility model which can effectively prevent the overflow of medicine liquid has the advantages of simple structure, low cost, and long service life.
Description
The utility model relates to a kind of knapsack sprayer.
At present, existing knapsack sprayer, mostly form by liquid storage cylindrical shell, pressue device and sprinkling output block, its liquid storage cylindrical shell generally all is to be made by PEF plastics or glass-reinforced plastic material, and the upper surface of its liquid storage cylindrical shell and bottom surface all are the plane, and this structure and used material have following deficiency: 1, the liquid storage cylindrical shell of being made by the PEF plastics blow molding, the intensity of cylindrical shell is little, during use, it is too big to return sliding coefficient between crank and link rod, inflator stopper rod, makes it expulsion pressure and reduces.2, the liquid storage cylindrical shell that adopts fiberglass to make, its cost height, and very easily broken.3, the upper surface of liquid storage cylindrical shell and bottom surface are planar structure, during use, soup very easily overflows in inlet or air cylinder cover, be dropped in user's back or shank, extremely unhygienic, severe patient can cause the user to poison, in addition, because bottom surface is easy and ground produces friction, easily causes liquid storage cylinder body drain liquid.
The purpose of this utility model is to provide a kind of cost low, long service life, and soup is difficult for being dropped in user's knapsack sprayer on one's body.
The purpose of this utility model is achieved in that this sprayer is made up of liquid storage cylindrical shell and the device for exerting that links with it, sprinkler part, its liquid storage cylindrical shell comprises cylindrical shell and upper and lower closing cap, on the neighboring of upper and lower closing cap, be respectively equipped with the convex edge, its upper and lower closing cap closely is equipped with by convex edge and cylindrical shell and is one, and having inlet on the closing cap thereon, the periphery of inlet is provided with the convex edge.
Also be provided with hole for back flow thereon on the closing cap.The material of said cylindrical shell and upper and lower closing cap adopts high pressure polychlorostyrene resin and plastic.
The utility model has the advantages that: the last closing cap of cylindrical shell is provided with the convex edge, can prevent effectively that the medicine liquid droplet that overflows from dropping on one's body the user, and can reclaim by the soup that hole for back flow will overflow.Following convex edge mainly prevents the bottom surface and the ground friction of cylindrical shell, and in the service life that can improve the liquid storage cylindrical shell, the liquid storage cylindrical shell adopts high pressure polychlorostyrene resin and plastic simultaneously, can strengthen the intensity of liquid storage cylindrical shell, and anticorrosion improves service life.
Be that embodiment further describes the utility model below with the accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the upper and lower end of liquid storage cylindrical shell 1 is bonding, fastening by screw again with the convex edge 4 of last closing cap 2, following closing cap 3 respectively by glue, makes the upper and lower end face of liquid storage cylindrical shell 1 be the dish shape.The centre position of last closing cap 2 has a circular inlet 5, and the periphery of inlet 5 is the convex edge, and the lid that matches is arranged again.The hole for back flow 6 that also to have a diameter on last closing cap 2 be 1cm reclaims the soup that overflows.Device for exerting is made up of pump 7, air chamber 8, connecting rod 9 and crank 10, pump 7 is installed in the side in the liquid storage cylindrical shell 1, the stopper rod 11 that is located at pump 7 upper ends links through connecting rod 9 and crank 10, the lower end of pump 7 is connected through feed liquor conduit and liquid storage cylindrical shell 1, open and close inlet opening with bead therebetween, pump 7 and air chamber 8 combine with tube connector, open and close fluid hole with bead therebetween.Form sprinkler part by spray boom 12 and shower nozzle 13, an end of spray boom 12 is connected on the air chamber 8, and soup flows to spray boom 12 by air chamber 8, from shower nozzle 13 ejections.
