Abstract

The utility model discloses a vertical sprayer, comprising an air chamber, a vertical double cylinder body, a piston, a connecting rod, a handle and a water sucking cover. A separating wall is arranged between a left cylinder body and a right cylinder body. The separating wall do work continuously when the handle is upward pulled and pressed downward. Therefore, continuous spraying can be obtained. The vertical sprayer has the advantage of light hand feeling. The utility model can be widely used for spraying pesticide to fruit trees, mulberries, garden trees, etc. The vertical sprayer is also suitable for deinsectization, hygiene and disease control in storehouses and slurry spraying for construction, etc.

Description

A kind of sprayer

The utility model relates to injection apparatus.

The cylinder body of existing sprayer divides horizontal and vertical two kinds, horizontal cylinder body horizontal positioned, and the handle horizontal movement drives the piston acting, produce pressure, the liquid that sucks is sprayed from liquid outlet, comparatively require great effort during operation, and the piston self gravitation is added on the barrel, and frictional resistance is bigger, can produce idle work; Vertical cylinder body is vertically placed, and direction of operating meets body mechanics's principle for vertically pressing down, and is comparatively laborsaving, and frictional force is little between piston and the barrel, and energy loss is little.But existing vertical sprayer has only single cylindricality cylinder body, and concrete operations are: acting when handle presses down, and on draw stroke stressed very little, therefore feel is still very heavy in working stroke.

The purpose of this utility model is the sprayer that a kind of vertical cylinder body will be provided, and draws and press down acting respectively in two strokes on handle, thereby under same piston area, each operating physical force is half of single cylinder.

The purpose of this utility model is achieved in that it comprises air chamber, cylinder body, piston, connecting rod, handle, imbibition lid, hydrojet sebific duct and nozzle, it is characterized in that described cylinder body is vertical twin-tub cylinder body, has partition walls between the cylinder body of the left and right sides.

Described cylinder body left-right symmetry, the cross section is rounded.

Described air chamber is positioned in the middle of the cylinder body of the left and right sides.

The utility model adopts the vertical cylinder body of twin-tub, makes the alternately acting of left and right sides cylinder body, and in each stroke that draws on handle and press down, and operating physical force only be half of single cylinder sprayer when exporting on an equal basis, so feel is lighter.Owing to continuous doing work, it also can obtain the effect of spraying continuously simultaneously.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a fundamental diagram of the present utility model.

Fig. 3 be A shown in Figure 1 place check valve structure and with cylinder body and hydraulic pressure lid between the amplification view that connects.

Represent in the accompanying drawing: 1--air chamber 2--piston 3--connecting rod 4--handle 5--cylinder body 6--imbibition lid 7--liquid sucting port 8--liquid outlet 9--bolt 10--check valve 11--valve seat 12--valve gap 13--ball 14--pad 15--partition walls 16--hydrojet sebific duct 17--nozzle

With reference to Fig. 1,2, sprayer comprises air chamber, vertical twin-tub cylinder body, piston, connecting rod, handle, imbibition lid, hydrojet sebific duct and nozzle, and left and right sides cylinder body is that symmetry is cylindrical, and there is partition walls the centre, air chamber is positioned in the middle of the cylinder body of the left and right sides, and is fixing by bolt and cylinder body and imbibition lid; Be respectively equipped with check valve between imbibition lid, air chamber and the left and right sides cylinder body, Figure 2 shows that the connecting mode of the structure of check valve and it and cylinder body and hydraulic pressure lid, the connecting mode between check valve and air chamber and cylinder body too; Liquid outlet connects hydrojet sebific duct, switch and nozzle successively.The place connects pipette at liquid sucting port, just can use.This device is installed on mounting or the vehicle frame usually, uses for convenience, and vehicle frame can be installed parts such as land wheel separately in the bottom.

With reference to Fig. 3, operation principle of the present utility model is such: when handle pressed down, left piston moved upward, and check valve 10-2 opens, and liquid sucks from the liquid sucting port of imbibition lid, and 10-2 enters left cylinder by check valve; Right piston moves downward simultaneously, and check valve 10-3 closes, and check valve 10-4 opens, and the liquid in the right cylinder body enters air chamber by check valve 10-4; When drawing on the handle, the working condition of left and right sides cylinder body is just in time opposite: left piston moves downward, and check valve 10-2 closes, and check valve 10-1 opens, and the liquid in the left cylinder enters air chamber by check valve 10-1; Right piston moves upward simultaneously, check valve 10-3 opens, liquid enters right cylinder body from the imbibition lid through check valve 10-3, so repetitive operation, liquid constantly alternately enters left and right sides cylinder body from the imbibition lid, enters air chamber then, forms certain pressure at the liquid outlet place of air chamber, through hydrojet sebific duct, hydrojet switch and nozzle atomization, just can obtain continuous spraying.This sprayer can be widely used in the insecticide spraying in fruit tree, mulberry tree, gardens etc., also is applicable to storage deinsectization, health and epidemic prevention and building whitewashing etc.
