Abstract

The utility model relates to an improved portable compression type sprayer. The inventor improves a piston and increases a check valve, a safety valve and an air door mouth in an inflating pump. After the sprayer is improved, air pressure is high. The existing phenomenon that a container is broken because of higher air pressure can be avoided, and the sprayer has convenient operation.

Description

Portable compression type sprayer

The utility model belongs to the improvement to the spraying instrument.

Used portable compact formula sprayer mostly is made up of accessories such as container, inflator, spray booms.The piston that is driven in the inflator by handlebar during operation moves up and down repeatedly, and air is compressed in the container that liquid into is housed, and forces solution by the liquid of woven hose from shower nozzle ejection atomizing shape.But this sprayer has several like this deficiencies:

The inflator sealing effectiveness is bad, be difficult to improve the gas pressure in the container, and container does not have high pressure resistant device yet.

For overcoming above deficiency, the inventor improves above-mentioned spray structure.

The present invention is achieved in that to making piston in the inflator effectively play the function of air inlet, compressed gas form piston by rubber ring and piston ring, piston ring is provided with air inlet; Be to increase the air pressure in the container, being provided with in inflator can anti-anticyclonic non-return valve, and is provided with safety valve, and when air pressure acquired a certain degree, the safety valve automatic deflation broke to avoid container.For easy to use, on inflator, be provided with valve cock again.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 is the schematic diagram of portable compact formula sprayer of the present utility model.

Fig. 2 is the section and the front view of portable compact formula sprayer piston of the present utility model.

Fig. 3 is the profile of portable compact formula sprayer non-return valve of the present utility model.

Fig. 4 is the safety valve profile of portable compact formula sprayer of the present utility model.

Handle 1 is fixed together with handle bar 2, the other end of handle bar 2 and piston 3 are fixed together, piston 3 is made up of plug ring 4 and rubber ring 5, plug ring 4 is to be trochlear by the plastics manufacturing, following plectane 6 is provided with 1～3 gas port 7, upper and lower plectane and central shaft 8 are made one, and centre bore 9 is used for handle bar 2 fixing.Rubber ring 5 is enclosed within on the central shaft 8 of plug ring 4, sees accompanying drawing 2.

Accompanying drawing 3 is schematic diagrames of non-return valve 10.Check 12 usefulness nylon are made the cone pulley shape, non-return valve glue ring 11 is placed on the air inlet 18 of non-return valve base 17 of inflator 16 bottoms, place check 12 successively, non-return valve spring 14 is enclosed within on the check guide rod 13, with check bonnet 15 they is fixed on the screw socket of inflator 16 bottom non-return valve bases 17 then.Check bonnet 15 covered 1～3 pore, check 12 and guide rod 13 are one.

Fig. 4 is the schematic diagram of safety valve 19.Glue ring 25 is located at the bottom of safety valve housing 22 in the safety valve, safety lever 20 passes 6～10 millimeters of safety valve housing 22 1 end centre bores, safety lever 20 have one be used for safety valve in glue ring 25 sealing and with the circular gasket 26 of safety lever 20 one, safety valve spring 21 is enclosed within safety lever pad 26 other ends on the safety lever 20, with safe bonnet 23 safety valve spring 21 is fixed on the safety valve housing 22.Safe bonnet 23 is provided with the centre bore concentric with safety valve housing 22.Safe bonnet 23 is provided with 1～3 safety valve steam vent 33 that diameter is about 0.4 millimeter.Put sealed rubber ring 24 safety valves 19 at safety valve base 27, be fixed with safety valve base cap 28, safety valve base cap 28 is provided with centre bore, makes safety lever 20 expose safety valve base cap 28.

For but this sprayer has enough air pressure, sealed rubber ring or rubber cushion generally all are set between each bonded block.

When using this sprayer, inject liquid from water filling port 29 and tighten loam cake 35, upper and lower twitch handle 1 also drives piston 3 and moves together.When toward container 30 compressed air, the rubber ring 5 in the piston 3 tightly leans against on the plectane, plays sealing function with inflator 16 for tight fit.Owing to be subjected to the compression of air, check 12 compression check valve springs 14 enter in the container 30 air.When piston 3 moved upward, because the elastic reaction of non-return valve spring 14, check 12 was got back to original position, can avoid the air in the container 30 to reveal by inflator.At this moment the rubber ring in the piston 3 abuts against down on the plectane 6, and gas enters inflator 16 from gas port 7.Motion repeatedly, air pressure in the container 30 constantly increases, when the air pressure in the container 30 increases to a certain ultimate pressure (as the 10kg/ square centimeter), safety valve 19 work, the elastic force that pressure in the container makes safety lever 20 overcome safety valve spring 21 outwards moves, with safety lever 20 be that the safety valve pad 26 of one moves simultaneously, at this moment the gas in the container 30 passes through from the space of safety lever 20 and safety valve housing 22, from safety bonnet 23, the pore of safety valve base cap 28 is discharged, to the air pressure in the container 30 is dropped in the scope of safe air pressure, safety lever 20 automatically resets under the effect of safety valve spring 21.

For easy to operate, selected the general valve cock of bicycle 34 for use, can directly in container 30, inflate by this valve cock with air compressor.

During spraying liquid, press nozzle switch, liquid sprays from shower nozzle by delivery port 31 and through about about one meter long plastic conduit 32 under the effect of container air pressure.

This sprayer is easy to use, the atmospheric pressure height, and spray effect is good.
