Description

Portable push type steam sprayer

Technical Field

The utility model belongs to the technical field of steam sprayers, and particularly relates to a portable pushing type steam sprayer.

Background

The sprayer is a short term of spraying equipment, and is an appliance for spraying liquid medicine or other liquid into mist by using the suction effect and uniformly spraying the liquid medicine or other liquid onto other objects. The sprayer comprises a smog machine and a steam sprayer, wherein the smog machine directly mixes the liquid medicine and water and then heats and sprays the mixture, but the liquid medicine is easily decomposed when heated at high temperature, so that the drug effect is affected; the steam sprayer divides the liquid medicine and water into two channels, the sprayer main machine is used for independently heating the water to form high-temperature high-pressure mist, then the liquid medicine at normal temperature and the high-temperature high-pressure mist are mixed and sprayed at the spray head, the liquid medicine at normal temperature is wrapped and clamped in the high-temperature high-pressure mist, the spraying is more uniform on the premise of ensuring the drug property, the spraying pressure is sufficient, and the spraying range is effectively improved. Because the steam sprayer has small volume and light weight relative to the smog machine. Therefore, the steam atomizer is more widely used.

At present, a knapsack sprayer is generally adopted as a steam sprayer, an operator needs to bear the weight of the sprayer and the box body in the use process, the labor intensity in the working process is high, the steam sprayer is easy to fatigue, the working efficiency is low, the steam sprayer is inconvenient to use in fields or forests for a long time, and the steam sprayer is not suitable for large-area crop spraying operation. On the other hand, from the aspect of safety, the pesticide box and the fuel tank are carried on back, and the phenomena of liquid leakage, liquid dripping and the like of pesticides or fuel oil often occur in operation, so that personal safety is influenced, and the operation safety of the sprayer is lower. In addition, after the inventor has conducted intensive studies, after the problem of negative back of the sprayer box body is solved, the steam sprayer can also be flexibly applied to the relevant field of steam cleaning, and the problems that the steam car washer or the steam cleaning machine is complex in structure, inconvenient to move and high in cost can be effectively solved.

Through searching, related steam sprayer structures have been disclosed in patent literature, such as chinese patent application No.: 201110086186.3, the utility model is named: a hand propelled agricultural sprayer comprises a hand push frame, a single wheel arranged at the bottom of the hand push frame, a sprayer bucket and a transmission device are arranged on the hand push frame, a swing rod for controlling the sprayer bucket to output liquid is connected with the transmission device, and a nozzle is communicated with the sprayer bucket through a pipeline. The single-wheel structure of this scheme is only used for walking, does not have storage space, has not only increased manufacturing cost like this, and like the atomizer cask flourishing back, when the ground of pothole (for example ridge) uses, easily appears rocking to finally make the atomizer cask take place not hard up with the junction of hand push frame, the problem that the atomizer cask emptys easily appears.

For another example, the Chinese patent application number is 2014104108918, and the utility model is named as follows: the hand-push sprayer can adjust the angle and the direction of the solar panel according to different operating environments and time periods during outdoor operation, so that the storage battery is charged in real time, and the endurance time of the hand-push sprayer is prolonged; meanwhile, aiming at the fact that the solar panel cannot work in overcast days or working environments, the power supply of the generator is set to ensure all-weather work of the hand-push sprayer. The scheme is complex in structure, not suitable for walking on the hollow ground, high in manufacturing cost and poor in practicality.

For example, the Chinese patent application number is 2006200282047, and the utility model is named as follows: a steam car washer is composed of electric part, steam cleaning part and pressure cleaning part. Under the condition that the pressure exists in the steam generator, the water in the water tank can be automatically supplied or stopped to the steam generator; the low water level of the water tank, the high water level of the steam generator, the low water level and the steam pressure are controlled by the electric part, and the warning and the control are automatically obtained. The steam in the steam generator washes the surface of the automobile through the high-pressure spray gun, and the cleaning liquid or the polishing agent in the cleaning liquid tank and the polishing agent tank can be sprayed out through another hose and the spray gun to clean the outer surface of the automobile. The steam car washer in this scheme is complicated in structure, and its sanitizer and steam can not spray simultaneously, have increased the washing step, when spraying sanitizer or glazing agent alone simultaneously, can not like fog droplet that evenly spray, its result of use remains to be further improved.
