Description

Spray gun

Technical Field

The utility model relates to a spray gun.

Background

The spray gun is a liquid spraying tool commonly used in life, and people can spray various liquids when disinfecting, sterilizing, cleaning, decontaminating and maintaining watering flowers. The main working principle of the spray gun is that the trigger is pulled, the trigger pushes the piston and the spring to enable the piston to move in the gun body, gas in the gun body flows and is sprayed out from the head cap, the trigger spring is loosened to enable the piston to reset, pressure in the gun body is reduced, pressure outside the gun body is unchanged, pressure difference is generated between the inside and the outside of the gun body, liquid is sucked into the gun body from the bottle body through the pressure difference, and then the liquid is sprayed out from the head cap through the piston extrusion. At present, the spray gun on the market guarantees that the pressure in the bottle keeps unchangeable with the inlet port that sets up on the rifle body, and this kind of spray gun is applicable to ordinary liquid, and when the bottle was equipped with volatile, easy carminative liquid, used after the certain time, can be full of gas in the bottle and lead to the bottle bloated, if not in time release gas and have the risk of explosion, need unscrew the bottle lid gassing this moment, and is comparatively troublesome.

SUMMERY OF THE UTILITY MODEL

In view of the defects of the existing spray gun, the technical problems to be solved by the utility model are as follows: the spray gun convenient for exhausting is provided, so that the air pressure inside and outside the bottle body is consistent, and the normal use of the spray gun is ensured.

In order to achieve the above object, according to one aspect of the present invention, the present invention is achieved by the following technical measures: a spray gun, comprising: the rifle body, the rifle body comprises horizontal part, vertical part, piston cylinder body, blast pipe and core vent, horizontal part one end is connected with the vertical part and is the L shape, and the contained angle department of horizontal part and vertical part is equipped with piston cylinder body, be equipped with the water service pipe I that runs through the horizontal part in the horizontal part, be equipped with the water service pipe II that runs through the vertical part in the vertical part, water service pipe I and water service pipe II and piston cylinder body intercommunication, the blast pipe is established in piston cylinder body's below and with vertical part parcel, blast pipe and the gaseous intercommunication in the bottle, still open the exhaust hole on the blast pipe, the exhaust hole is sealed by the core vent, the core vent is equipped with the centre bore to be equipped with waterproof ventilated membrane in the outside of centre bore.

This spray gun rifle body is last to set up blast pipe and core vent, when there is volatile, easily carminative liquid in the bottle, unnecessary gas can be through blast pipe and core vent discharge bottle, keeps the inside and outside atmospheric pressure of bottle unanimous, ensures the normal use of spray gun.

Furthermore, an included angle of 45 degrees is formed between the piston cylinder body and the exhaust pipe and between the horizontal parts.

Compared with the prior art, the utility model has the advantages that: when volatile and easily-exhausted liquid exists in the bottle body, redundant gas can be exhausted out of the bottle body through the exhaust pipe and the exhaust plug, the pressure inside and outside the bottle body is kept consistent, and the normal use of the spray gun is ensured.

Description of reference numerals: 1. a horizontal portion; 2. a vertical portion; 3. a piston cylinder; 4. an exhaust pipe; 5. a vent plug; 6. a waterproof breathable film; 7. a water pipe I; 8. a water pipe II; 9. and (4) exhausting holes.

Detailed Description

The utility model will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Example 1

Referring to fig. 1 and 2, the spray gun of the present embodiment comprises a horizontal part 1, a vertical part 2, a piston cylinder 3, an exhaust pipe 4 and an exhaust plug 5, wherein the right end of the horizontal part 1 is connected with the upper end of the vertical part 2 and is L-shaped, the piston cylinder 3 is arranged at the included angle between the horizontal part 1 and the vertical part 2, a water pipe i 7 penetrating the horizontal part 1 is fixed in the horizontal part 1, a water pipe ii 8 penetrating the vertical part 2 is fixed in the vertical part 2, the bottom of the water pipe ii 8 is connected with the water pipe to be in contact with the liquid in the cylinder, the water pipe i 7 and the water pipe ii 8 are communicated with the piston cylinder 3, the exhaust pipe 4 is fixed below the piston cylinder 3 and wraps the vertical part 2, the exhaust pipe 4 is communicated with the gas in the cylinder, and the piston cylinder 3 and the exhaust pipe 4 and the horizontal part 1 form an included angle of 45 degrees as a preferable structure, so that the structure of the spray gun is more compact, the right side of the exhaust pipe 4 is provided with an exhaust hole 9, the exhaust hole 9 is movably sealed by an exhaust plug 5, the exhaust plug 5 is provided with a horizontal central through hole, and the right side of the central through hole is fixed with a waterproof breathable film 6.

During the use, liquid is through the blowout of water service pipe I7, water service pipe II 8 and piston cylinder body 3 from rifle head department, and when liquid in the bottle volatilizees or exhaust gas leads to bottle internal gas pressure to be greater than external atmospheric pressure, the gas in the bottle can be discharged through waterproof ventilated membrane 6, ensures that bottle internal gas pressure is unanimous with other external world, guarantees the normal use of spray gun.

Through the institutional advancement to the rifle body, set up blast pipe and core vent on the rifle body, when there is volatile, easily carminative liquid in the bottle, unnecessary gas can be through blast pipe and core vent exhaust bottle, keeps the inside and outside atmospheric pressure of bottle unanimous, ensures the normal use of spray gun.
