Abstract
The utility model relates to a non-global spray pump, characterized in that the utility model comprises a pump body, a pump bonnet, an upper piston, a lower piston and a spring. The spring and the lower piston are arranged in the pump body. The bottom of the spring is arranged on the liquid inlet, which is arranged at the bottom of the pump body. The top of the spring is arranged on the spring eye, which is arranged at the bottom of the lower piston. A liquid outlet hole is arranged in the upper piston. The bottom of the upper piston is arranged in the pump body to make the top of the lower piston be inserted in the upper piston and support the liquid outlet hole of the upper piston. The pump bonnet is arranged on the top of the pump body. The utility model has the advantages of the ability of spraying strong solution, less assemble working procedure and lower production cost.
Description
One, technical field
The utility model relates to a kind of atomizing pump, relates in particular to a kind of no ball-type atomizing pump.
Two, technical background
Common liquid atomizing pump generally is made up of the pump housing, pump cover, gland, upper and lower piston, valve rod, spring, glass marble and suction pipe etc.On upper piston, load onto nozzle during use and press head; Press during spraying and press head, valve rod is opened thereupon, and liquid is pressed onto mentioned nozzle area by the upper piston hole in the pump housing, and liquid is ejection fast under the effect of pump internal pressure.Owing in this atomizing pump pump glass marble is arranged, act on piston and glass marble by valve rod in the pump, act on the pump housing by glass marble again, feed liquor or longer by reaching the prevention time, thereby cause a little less than the explosive force, can't carry out supercharging in the short time and mist formation to concentrated solution, this in addition atomizing pump is because part is many, its assembling procedure is many, and assembly cost and production cost are also high.
Three, technology contents
At above-mentioned shortcoming, the no ball-type atomizing pump that the purpose of this utility model is to provide a kind of can spray to concentrated solution, assembling procedure is few, production cost is low.
Technology contents of the present utility model is that a kind of no ball-type atomizing pump is characterized by it and comprises the pump housing, pump cover, upper and lower piston and spring; Spring and lower piston place in the pump housing, and the spring lower end places the feed liquor place of pump housing bottom, and the top of spring places in the spring eye of lower piston lower end; One fluid hole is arranged in the upper piston, and the lower end of upper piston places in the pump housing, and lower piston top is inserted in the upper piston, and withstands the fluid hole of upper piston; Pump cover places the upper end of the pump housing.
The advantage that the utility model is compared with prior art had:
1, owing to no glass marble in the atomizing pump pump, spraying explosive force is strong, can spray to concentrated solution.
2, because the atomizing pump part is few, and its assembling procedure is few, assembly cost and production cost are just low.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiment
As shown in Figure 1, a kind of no ball-type atomizing pump is characterized by it and comprises the pump housing 1, pump cover 2, upper and lower piston 3,4 and spring 5; Spring 5 and lower piston 4 place in the pump housing 1, and spring 5 lower ends place inlet opening 1.1 places of the pump housing 1 bottom, and the top of spring 5 places in the spring eye 4.1 of lower piston 4 lower ends; One fluid hole 3.1 is arranged in the upper piston 3, and the lower end of upper piston 3 places in the pump housing 1, and lower piston 4 tops are inserted in the upper piston 3, and withstands the fluid hole 3.1 of upper piston 3; Pump cover 2 places the upper end of the pump housing 1.Electrification aluminium gland 6 is sleeved on pump cover 2 upper ends.
On upper piston, load onto nozzle when installing and using and press head; Press during spraying and press head, liquid enters in the pump housing 1 from the inlet opening 1.1 of the pump housing 1, and the fluid hole 3.1 by upper piston 3 is forced into mentioned nozzle area again, and liquid is ejection fast under the effect of pump internal pressure.
