Abstract
The utility model discloses a spray device which is provided with a cylinder seat. The left and the right sides of the cylinder seat are provided with two upright cylinders, an air chamber is arranged between the two cylinders, and the inner part of each of the cylinders is provided with pistons which are connected with a middle connecting rod of an E-shaped connecting rod. The front and the back sides of the cylinder seat are provided with rocker arm supporting seats, V-shaped rocker arms are arranged on the rocker arm supporting seats, and both ends of the front and the back V-shaped rocker arms are connected respectively with the connecting rods at both sides of the E-shaped connecting rod of the left and the right cylinders; one end of the front and the back V-shaped rocker arms then is connected with the handle, and one-way valves are arranged respectively among the two cylinders, the air chamber and a liquid inflow chamber. The utility model has the advantages of simple, firm and smooth structure and long service life, makes a left and a right cylinder bodies apply work continuously, can bring the pressure, and can obtain the continuous spraying effect.
Description
The utility model relates to spraying mechanical, relates in particular to sprayer.
A kind of manual medical instruments are used to spray insecticide with prevention and elimination of disease and pests, also are used for sanitary desinsection and sterilization.By liquid pump (or air pump), formations such as air chamber (cartridge of compressed sprayer is also used as air chamber, and sprayer-intermittent does not have air chamber) and injecting-unit.The cylinder body of sprayer divides bedroom and vertical two kinds, and the piston acting that handle motion drives air pump produces pressure the liquid that sucks is sprayed from liquid outlet.Usually sprayer exists frictional resistance big, shortcomings such as parts rapid wear.
The purpose of this utility model provides a kind of sprayer.
For on the utility model that achieves the above object take following measures:
Sprayer has cylinder block, be provided with two upright cylinders in the cylinder block left and right sides, be provided with air chamber between two cylinders, be provided with piston in the cylinder, and link to each other with the intermediate connecting rod of mountain font connecting rod, both sides are provided with the rocking arm supporting base before and after cylinder block, on the rocking arm supporting base, be provided with the V-arrangement rocking arm, before and after two V-arrangement rocking arm two ends respectively with about the both sides connecting rod of mountain font connecting rod of two cylinders link to each other, the one end links to each other with handle again, about be respectively equipped with check valve between two cylinders and air chamber and the intake chamber, air chamber is provided with liquid outlet, intake chamber is provided with liquid sucting port.
Advantage of the present utility model: simple in structure, firm, steady, long service life, left and right sides cylinder body continuous doing work can be with pressure, can obtain continuous spray effect.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is the spray structure schematic diagram.
Sprayer has cylinder block, be provided with two upright cylinders 4 in the cylinder block left and right sides, be provided with air chamber 1 between two cylinders, be provided with piston 2 in the cylinder, and link to each other with the intermediate connecting rod of mountain font connecting rod 3, both sides are provided with rocking arm supporting base 11 before and after cylinder block, on the rocking arm supporting base, be provided with the V-arrangement Rocker arm 5, before and after two V-arrangement rocking arm two ends respectively with about the both sides connecting rod of mountain font connecting rod of two cylinders link to each other, the one end links to each other with handle 10 again, about be respectively equipped with check valve 7 between two cylinders and air chamber and the intake chamber 6, air chamber is provided with liquid outlet 8 intake chamber and is provided with liquid sucting port, the cylinder block bottom is provided with hold-down support 9.
During use, handle presses down, left piston moves upward, intake chamber's left side one-way valve opens, liquid enters left cylinder from intake chamber by intake chamber's left side check valve, and right piston moves downward simultaneously, the right closed check valve of intake chamber, the right one-way valve opens of air chamber, the liquid in the right cylinder enters air chamber by the right check valve of air chamber.When drawing on the handle, left piston moves downward, intake chamber's left side closed check valve, air chamber left side one-way valve opens, liquid in the cylinder of a left side enters air chamber by air chamber left side check valve, and right piston moves upward simultaneously, the right one-way valve opens of intake chamber, liquid enters right cylinder by the right check valve of intake chamber, so repetitive operation, liquid constantly alternately enters left and right sides cylinder from intake chamber, enters air chamber then, make air chamber have certain pressure, open nozzle and just can obtain continuous spraying.
