Existing vehicle-mounted inflation mechanism is made up of plunger air pump, valve, compression indicator, pneumatic head.The plunger air pump is made up of DC machine, crank linkage driving system, the pump housing; Cylinder is provided with admission port behind the pump housing, admission port is provided with check valve sheet, the piston that pump housing protecgulum is provided with air extractor duct, the pump housing is provided with a plurality of pores, the preceding cylinder face capping of pore has check valve sheet, when the piston forward cylinder advances, the cylinder compression pressure covered pore before check valve sheet was subjected to, and piston pushes away preceding cylinder gas forward, and pressure gas is discharged from the protecgulum exhausr port.And this moment, the back cylinder produced negative pressure, from back cylinder admission port check valve sheet aspirated air; When piston moved backward, cylinder was waited for pushes compression gas before the piston of following one-period before the gas of back cylinder was pushed check valve sheet on the piston open and entered, and it is not high that this plunger air pump is inflated pressure, and efficient is low.

How spray carwash at present at The Wash, lose time when crowded, expense is also high.And vehicle-mounted inflation mechanism can only be inflated, and its structure pump pressure is low can not pump water, can not realize dual-use.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point, and a kind of carwash inflation dual-purpose apparatus is provided.

Scheme of the present utility model is: comprise plunger air pump, valve, compression indicator, pneumatic head, the accumulator, the hydraulic giant that also comprise the carwash injection equipment, it is characterized in that: the piston of the pump housing of plunger water pump is not for establishing the packed-piston dish of pore, the cylinder admission port is not established check valve sheet behind the pump housing, the protecgulum of the pump housing also is provided with air suctiton inlet, be provided with the check valve sheet of capping air suctiton inlet at preceding interior surface, protecgulum air suctiton inlet outside face disjunctor extends aspirate tube, is sheathed with suction gas flexible pipe on the aspirate tube; Tubular body of protecgulum exhausr port outside face disjunctor extension, the tubular body internal diameter is greater than diameter of outlet, discoid slide plate running-fit is enclosed within the tubular body endoporus and is sealed on the exhausr port, its outside thread is twisted to be combined in and is implemented in the tubular body external port negative thread to fix behind the step disc type block fit seal ring, and a compression spring is oppressed between slide plate and block; The tubular body sidewall disjunctor radial tubes that extends, the entrance point of the radial tubes other end and the three way type electromagnetic valve of setting up fixedly communication type is connected, and exit end of three way type electromagnetic valve passes through a pipeline and docks with pneumatic head, is plugged with compression indicator on the described pipeline; Another exit end of three way type electromagnetic valve and accumulator entrance point pipeline connection, accumulator exit end and entrance point pipeline connection of " bifurcation " font threeway, described " bifurcation " font threeway exit end and hydraulic giant entrance point soft pipe connection; Set up a washer solvent jar, the washer solvent jar is made up of barrel and the capping loam cake on it, the barrel bottom is provided with discharge port, loam cake is provided with air suctiton inlet and inlet point, upper interior surface is fixed with the check valve sheet of capping air suctiton inlet, and a block outside thread is twisted to be combined in and implemented in the loam cake inlet point negative thread to fix; Washer solvent jar lower drain port is communicated with another entrance point of " bifurcation " font threeway by pipeline.

Advantage of the present utility model is: after the plunger air pump repacking not only inflation pressure greatly improve, use but also can be used as plunger type water pump, the pump hydraulic pressure also can satisfy the carwash demand, reaches a machine dual-purpose purpose.

Description of drawings:

Accompanying drawing is the utility model structural representation.

The specific embodiment:

The utility model comprises plunger air pump 1, valve, compression indicator 8, pneumatic head 5, the accumulator 2, the hydraulic giant 4 that also comprise the carwash injection equipment, it is characterized in that: the piston of the pump housing of plunger water pump is not for establishing the packed-piston dish of pore, the cylinder admission port is not established check valve sheet 12 behind the pump housing, the protecgulum 13 of the pump housing also is provided with air suctiton inlet, be provided with the check valve sheet 12 of capping air suctiton inlet at protecgulum 13 inside faces, protecgulum 13 air suctiton inlet outside face disjunctors extend aspirate tube 11, is sheathed with suction gas flexible pipe 10 on the aspirate tube 11; Tubular body 9 of protecgulum 13 exhausr port outside face disjunctors extension, tubular body 9 internal diameters are greater than diameter of outlet, discoid slide plate running-fit is enclosed within tubular body 9 endoporus and is sealed on the exhausr port, its outside thread is twisted to be combined in and is implemented in the tubular body 9 external port negative threads to fix behind the step disc type block fit seal ring, and a compression spring is oppressed between slide plate and block; Radial tubes 7 of tubular body 9 sidewall disjunctors extension, the entrance point of radial tubes 7 other ends and the three way type electromagnetic valve of setting up 6 fixedly communication type is connected, 6 one exit end of three way type electromagnetic valve dock with pneumatic head 5 by a pipeline, are plugged with compression indicator 8 on the described pipeline; Three way type electromagnetic valve 6 another exit end and accumulator 2 entrance point pipeline connections, accumulator 2 exit end and entrance point pipeline connection of " bifurcation " font threeway, described " bifurcation " font threeway exit end and hydraulic giant 4 entrance point soft pipe connections; Set up a washer solvent jar 3, washer solvent jar 3 is made up of barrel and the capping loam cake on it, the barrel bottom is provided with discharge port, loam cake is provided with air suctiton inlet and inlet point, upper interior surface is fixed with stubborn being combined in of 12, one blocks of check valve sheet outside thread of capping air suctiton inlet and implements in the loam cake inlet point negative thread to fix; Washer solvent jar 3 lower drain ports are communicated with another entrance point of " bifurcation " font threeway by pipeline.

Accumulator 2 roofs are plugged with pressure contact switch 14, and pressure contact switch 14 is connected with the electric power switch circuit of plunger air pump 1.

Suction gas flexible pipe 10 is put into then plunger pump pump washing car of water, places air then to do inflation and uses.Protecgulum 13 is set up air suctiton inlet and is used check valve sheet 12, because the soft elasticity of thin board type valve block sheet is big, make air inlet, the water inlet resistance little, it is big that exhausr port is provided with its elastic force of compression spring slide plate, the air pressure of discharge or hydraulic pressure are improved, because suction and discharge one-way valve structures form difference, pressure gap, so this device can pump gas, also can pump water, just can reach a machine dual-purpose.6 effects of three way type electromagnetic valve are pump water and the conversion of pump gas two-way fast reliably.The placement washer solvent makes it pump washing Che Shike and takes washer solvent out of tank body by the negative pressure that the threeway of " bifurcation " font produces in the washer solvent jar 3, is blended in the water and is sprayed by hydraulic giant 4, and two entrance point acute angle shapes of " bifurcation " font threeway help the negative pressure vapor.The setting of washer solvent check valve sheet 12 is that valve block is opened in the jar during negative pressure, and washer solvent could be discharged by discharge port, and its block uses during as additive liquid.

Grafting pressure contact switch 14 on the accumulator 2 surpasses setting value when accumulator 2 hydraulic pressure rise, and the motor power circuit is cut off in 14 actions of pressure contact switch, in case overvoltage, and saves energy.
