Dual-purpose device for vehicle cleaning and air inflation

Abstract

The invention relates to a dual-purpose device for vehicle cleaning and air inflation, and relates to a vehicle cleaning injection mechanism and an air inflation mechanism. The dual-purpose device is characterized in that: a front cover of a pump body is provided with an air suction port with a one-way valve plate; a steam suction hose is sleeved on an air suction pipe of the extension of the air suction port on the front cover; an inner hole of a tubular body of the extension of an exhaust port on the front cover is provided with a sliding sheet to cover on the exhaust port; a compression spring is compressed between the sliding sheet and a cover cap by the cover cap; the side wall of the tubular body extends to form a radial tube in a one-piece mode; one outlet end, which is communicated with the radial tube, of a three-way solenoid valve is in butt joint with an air inflation head by a pipeline, and the other outlet end of the three-way solenoid valve is communicated with a pipeline at one inlet end of a 'Y'-shaped tee joint by a pressure storage tank; the outlet end of the 'Y'-shaped tee joint is communicated with a hose at the inlet end of a water syringe; the lower part of a detergent tank which is arranged additionally is provided with a drainage port; the air suction port and a feed port are formed on an upper cover; the one-way valve plate is fixed on the inner surface of the upper cover; and the drainage port on the lower part of the detergent tank is communicated with the other inlet end of the 'Y'-shaped tee joint by the pipeline. The dual-purpose device has the advantage of fulfilling the aim of one machine with dual purposes.

Description

Technical field: [0001] The invention relates to a car washing injection mechanism and an inflation mechanism, in particular to a car washing and inflation dual-purpose device. Background technique: [0002] Existing car washing injection mechanism is made up of water pump, valve, pressure gauge, pressure storage tank, water gun. The water pump can be a gear pump, a plunger pump, or a centrifugal pump, and the water is pumped into the pressure storage tank, and then the outlet of the pressure storage tank is covered with a hose to communicate with a water gun to implement jetting car washing. [0003] Existing vehicle-mounted inflation mechanism is made up of plunger air pump, valve, pressure gauge, inflation head. The plunger air pump is composed of a DC motor, a crank connecting rod transmission mechanism, and a pump body; an air inlet is arranged on the rear cylinder of the pump body, a one-way valve is arranged on the air inlet, an air outlet is arranged on the front co...

Problems solved by technology

At this time, the rear cylinder generates negative pressure, and the air is inhaled from the one-way valve plate of the air inlet of the rear cylinder; when the piston moves backward, the gas in the rear cylinder pushes the one-way valve plate on the piston and enters the front cylinder to wait for the next cycle of the piston Push the compressed gas forward, the pumping pressure of this plunger air pump is not high, and the efficiency is low

[0004] At present, jet car washes are mostly used in car wash shops, which wastes time and costs a lot when crowded.

However, the vehicle-mounted inflatable mechanism can only inflate, and its structural pump cannot pump water when the pressure is low, so it cannot realize one machine with two functions.
