Description

Portable sprayer

(I) technical field

The utility model relates to a practical novel instrument that uses when carrying out blade surface water spray, fertilizer spraying and harmful organism prevention and cure and prevent and cure pests such as mosquito, fly in courtyard in vegetables, flower planting, agriculture and forestry production, convenient and flexible, simple manufacture, convenient for material collection when using is difficult for destroying moreover.

(II) background of the invention

Harmful organisms in vegetable and flower planting, agricultural and forestry production and human living environment often cause great harm to agricultural and forestry production due to large reproduction quantity and rapid spread, and have great influence on human life. When spraying water to leaf surfaces, spraying fertilizers and preventing and controlling plant diseases and insect pests and preventing and controlling pests such as mosquitoes and flies in courtyards in vegetable and flower planting and agriculture and forestry production, timely prevention and control are needed due to strong temporary property, and people often use a sprayer to spray during prevention and control. The traditional operation method is to purchase a manual pressure sprayer in the market for operation, which not only wastes liquid medicine, but also causes damage and inconvenient use of the purchased sprayer due to complex structure and fine parts.

Disclosure of the invention

The utility model aims at providing a can carry out blade surface water spray, fertilizer spraying, pest control in vegetables, flower planting, agriculture and forestry production and in the courtyard when preventing and control pests such as mosquito, fly facilitate the use, draw materials simple manufacture, be difficult for the portable atomizer of damage moreover.

The utility model provides a technical scheme that its technical problem adopted is: the bottle cap is characterized by comprising a hard plastic bottle, a liquid guide pipe and an air inlet valve, wherein the liquid guide pipe is a bent pipe outside the bottle cap, the outer end of the liquid guide pipe is provided with a spray head, the bottom of the liquid guide pipe inside the hard plastic bottle is provided with a filter cap, and the filter cap is arranged at the bottom of the hard plastic bottle; a sealing ring is arranged between the liquid guide pipe and the bottle cap; the upper part of the air inlet valve arranged on the bottle cap is provided with a transverse pin, and the lower part of the air inlet valve is provided with a transverse round sealing sheet.

The utility model has the advantages that: carry out blade surface water spray, fertilizer spraying, spout the medicine in to vegetables, flowers, agriculture and forestry production to and can operate fast, conveniently when carrying out medicament prevention and cure to mosquito, fly in the courtyard, improve work efficiency, its simple structure, the preparation of drawing materials is convenient, the operation is safe swift, is difficult for destroying moreover.

(IV) description of the drawings

The invention will be further described with reference to the following drawings and examples:

fig. 1 is a schematic longitudinal sectional structure of the present invention.

In the figure: 1 spray head, 2 sealing rings, 3 hard plastic bottles, 4 air inlet valves, 5 bottle caps, 6 liquid guide pipes and 7 filter caps.

(V) detailed description of the preferred embodiments

The attached drawing is a concrete embodiment of the utility model. This embodiment comprises a rigid plastic bottle 3, a liquid conduit 6 and an air inlet valve 4, characterized in that: the liquid guide tube 6 is a bent tube outside the bottle cap 5, the outer end of the liquid guide tube 6 is provided with the spray head 1, the bottom of the liquid guide tube 6 inside the hard plastic bottle 3 is provided with the filter cap 7, and the filter cap 7 is arranged at the bottom inside the hard plastic bottle 3; a sealing ring 2 is arranged between the liquid guide tube 6 and the bottle cap 5; the upper part of an air inlet valve 4 arranged on a bottle cap 5 is provided with a transverse pin, and the lower part is provided with a transverse round sealing sheet.

During operation, the bottle cap 5 is unscrewed, clean water, fertilizer liquid or liquid medicine to be sprayed is injected into the hard plastic bottle 3, the spray head 1 is aligned to a position to be sprayed, the bottle body of the hard plastic bottle 3 is held and extruded by one hand, and due to the sealing ring 2 arranged between the liquid guide pipe 6 and the bottle cap 5, the air inlet valve 4 moves upwards under the action of air pressure in the hard plastic bottle 3 and blocks a gap between the air inlet valve 4 and the bottle cap 5, so that the air in the hard plastic bottle 3 is prevented from overflowing outwards. Therefore, the hard plastic bottle 3, the bottle cap 5 and the sealing ring 2 form a closed space, the air pressure in the hard plastic bottle 3 is increased under the extrusion effect, so that the clear water, the fertilizer liquid or the liquid medicine in the hard plastic bottle 3 can only move upwards and towards the spray head 1 along the liquid guide pipe 6 after passing through the filter cap 7, and when the clear water, the fertilizer liquid or the liquid medicine moves to the position of the spray head 1, the clear water, the fertilizer liquid or the liquid medicine continuously moves outwards and forms fog drops to be sprayed to the position needing spraying. After the hard plastic bottle 3 is squeezed to a certain degree, the hand holding the hard plastic bottle 3 is released, the bottle body of the hard plastic bottle 3 is popped out outwards under the self elasticity, thus, the pressure in the hard plastic bottle 3 is reduced, the air inlet valve 4 moves downwards under the action of gravity and the air pressure outside the hard plastic bottle 3, the air enters the hard plastic bottle 3 from the gap between the air inlet valve 4 and the bottle cap 5, after the air enters to a certain degree, the hard plastic bottle 3 is continuously held by the hand and squeezed to continue spraying. After the spraying of the clear water, the fertilizer liquid or the liquid medicine in the hard plastic bottle 3 is finished, the bottle cap 5 is unscrewed, the clear water, the fertilizer liquid or the liquid medicine to be sprayed is injected into the hard plastic bottle 3, the bottle cap 5 is screwed down, and the operation is continued.
