1. The utility model provides an energy-conserving high-efficient shower nozzle combination of backpack sprayer, includes shower nozzle, water jet (2), places volume regulating valve (5), infusion pipe interface (4) on the shower nozzle in, its characterized in that: be equipped with the spout on the shower nozzle, the one end that shower nozzle and long return bend meet is circular (3), connects on volume regulating valve (5) through round hole (6) on the shower nozzle in water jet (2), water jet (2) constitute by first section (7), tail section (9) and interlude (8) of connecting the two.

2. The energy-saving and high-efficiency spray head combination of the backpack sprayer according to claim 1, which is characterized in that: the nozzle of the spray head is a flat fan-shaped nozzle (1).

3. The energy-saving and high-efficiency spray head combination of the backpack sprayer according to claim 1, which is characterized in that: the nozzle of the spray head is an elliptical nozzle (11).

4. The energy-saving and high-efficiency spray head combination of the backpack sprayer according to claim 1, which is characterized in that: the first section (7) of the water nozzle (2) is a hollow bolt, the middle section (8) is a hollow long triangular body with a water outlet hole, and the tail section (9) is a cylinder with a rotary handle.

Technical Field

The invention relates to a spray head combination, in particular to a spray head combination matched with a knapsack sprayer.

Background

The power of a gasoline engine which is equipped with the knapsack sprayer and has a long range is correspondingly high when the knapsack sprayer is used, the corresponding oil consumption is high, and the spraying effect of the existing spray head is not ideal.

Disclosure of Invention

In order to solve the defects in the prior art, the invention provides a novel energy-saving and high-efficiency spray head combination of a backpack type sprayer, the use mode of the spray head combination does not change the use habits of people, and the problems of high oil consumption and unsatisfactory spraying effect are solved.

In order to realize the aim, the energy-saving and high-efficiency spray head combination of the backpack sprayer comprises a spray head and a water spray nozzle.

The nozzle of the nozzle is flat fan-shaped, the end of the nozzle connected with the long bent pipe is still round, and the nozzle is also provided with a metering valve, an infusion pipe interface and a round hole for installing a water nozzle.

The water nozzle consists of a first section, a tail section and a middle section for connecting the first section and the tail section, wherein the first section is a hollow bolt, the middle section is a hollow long triangular body with a water outlet hole, and the tail section is a cylinder with a rotary handle.

The water nozzle is connected with the metering valve through a round hole on the spray head.

The nozzle of the spray head can also be an elliptical nozzle or other nozzle with a flat main structure.

By adopting the technical scheme, the aims of reducing oil consumption and having good spraying effect can be achieved. The spout adopts flat fan-shaped spout, reduces the power of gasoline engine and just can reach the range and spray the equal ideal purpose of effect, according to under the same circumstances of power, circular spout is held between the fingers flat back range and can be known by this principle of increase: under the condition of the same range, the power of the gasoline engine required by the flat nozzle is lower than that of the gasoline engine required by the circular nozzle, the power is lower, the oil consumption is lower, and the purposes of energy conservation and emission reduction are achieved; the spraying effect takes cotton as an example, the flat fan-shaped nozzle can fully and thoroughly spray the cotton plant from top to bottom; the middle section of the water spray nozzle adopts a long triangular body, and the water outlet holes are formed in the positions, close to the windward angle, of the two windward surfaces of the long triangular body, so that liquid is easy to break away by airflow, and the sprayed mist is thinner; the round hole is arranged on the spray head, so that the water spray nozzle is convenient to install. By adopting the structure, the structure is simple, the use is convenient, and the energy conservation and the high efficiency are realized.
