Abstract

The utility model discloses a return spray gun structure, which consists of a control handle, a water delivering device and a spray nozzle component. A valve seat is arranged in front of the control handle, is controlled by a trigger and can convey high pressure air and one side thereof is connected with an injection pipe through a connecting pipe. A water outlet pipe is arranged in the connecting pipe and can pass through the bottom of the connecting pipe and be connected with the water delivering device. The other side of the connecting pipe relative to the control handle is provided with a joint end which can be sleeved with the injection pipe in order to be connected with a conveying pipe for the water outlet pipe passing through the supplied water and the entrance of the high pressure air transmitted by the connecting pipe. The other side of the conveying pipe away from the joint end penetrates a bushing and is connected with a bent pipe joint through a cohesion pipe at one side in the bushing. When the high pressure air and water is spayed out from the bent pipe in the injection pipe, the bent pipe is driven to rotate smoothly and axially through the assistance of two or more than two bearings outside the conveying pipe and the cohesion pipe in the bushing. Because the material is nonflexible, the bent pipe does not break and is durable when rotating under high pressure and at high speed.

Description

Return the power spray gun structure

Technical field

The utility model relates to the power spray gun structure a kind of time.

Background technology

At present, general cleaning all can need the water flushing, scrubs, smears wiping through hairbrush, rag etc. again; And when vehicle carried out washing and cleaning operation, then need auxiliary washing and cleaning operations such as more powerful water column, hairbrush, napkin.Yet, utilize hairbrush, napkin etc. to do the mode that cleaning is scrubbed after the bath of traditional type again, not only consuming time taking a lot of work more wasted a large amount of waters, do not meet the water-saving requirements of saving energy fully.Return the power spray gun so occurred a kind of pneumatics on the market, as shown in Figure 7, return the part cross-sectional schematic of power spray gun structure for habitual pneumatics, its spary rifle A is by handle A1, T type pipe A2, parts such as liquid cylinder A3 and jet pipe resistor B are formed, and nozzle component B includes oviduct B1, oviduct B1 one end is provided with spiral shell seat B11, be bolted in the pressure air port of export A4 of spary rifle A, the outer end of oviduct B 1 is set as open shape, and at the screw thread of the pressure air port of export A4 of spary rifle A central authorities, locking can be spirally connected for the short circuit head C1 that returns solenoid C of plastic material, and go back to solenoid C external diameter appropriate position and be provided with weighting tube C2, spary rifle A by the extraneous pressure-air of handle A1 input after, A2 transfers to pressure air port of export A4 through T type pipe, pressure-air at T type pipe A2 place by the venturi tube effect, water in the liquid cylinder A3 is drained out, and at pressure air port of export A4 with after the water that drains out mixes, outwards spray by returning solenoid C, be used to clean the cleaned object of appointment.

But but there are many drawbacks in existing time power spray gun structure when reality is used, as:

1, in oviduct B1, does axial rotation and whipping owing to return solenoid C, and return solenoid C and go up sheathed weighting tube C2 and can accelerate rotary speed, make soft time made solenoid C of plastic material produce the tired and fracture damage of plasticity easily so cross long rotation by centrifugal force.

When 2, this time solenoid C axially rotated in oviduct B1, returning the upward sheathed weighting tube C2 of solenoid C can produce collision, rub with oviduct B1 internal face, and the axial rotary speed of the solenoid that slows down back C causes oviduct B1 internal face to produce abrasion simultaneously.

The utility model content

Main purpose of the present utility model is to provide a kind of bearing to rotate, have not easy fracture and durable time power spray gun structure at a high speed.

For reaching above-mentioned purpose, of the present utility model time the power spray gun structure comprises control handle, water delivery device and nozzle component, this control handle bottom is provided with the air inlet that can link the external high pressure air, control handle the place ahead is provided with the valve seat that can carry pressure-air with trigger control, and be connected with playpipe by tube connector in valve seat one side, be provided with the outlet pipe that can pass tube connector bottom and connect water delivery device in the tube connector, but and tube connector control relatively handle in addition side be provided with the abutting end of socket playpipe; Abutting end is connected with the carrier pipe of nozzle component, can confess water pipe in this carrier pipe and penetrate and supply water and gases at high pressure that tube connector transmitted enter; And be arranged with the sleeve pipe that can on carrier pipe, rotate on the carrier pipe respectively and be arranged at two or more bearings in this sleeve pipe; Sleeve pipe is socketed with bending tube with the horizontally disposed non-soft materials of carrier pipe at opening part, and outlet pipe is extended the port that wears to this bending tube by carrier pipe.

Beneficial effect after the employing technique scheme is:

1, because the bending tube of nozzle component is that to have the non-soft materials of better structural strength and toughness made, thus when bending tube when spraying the inner axial tube rotation, be difficult for producing fracture or breakage, increase its service life.

2, be arranged with rotating sleeve pipe on the carrier pipe, bending tube that can the auxiliary block post socket is in the inner smooth and easy rotation at high speed of playpipe, can not make its because of with the playpipe internal face produce rub impaired.

3, gases at high pressure can be mixed the spary rifle structure that sprays with Waterflow-guiding to playpipe, when bending tube ejection gases at high pressure and water in playpipe, can drive bending tube axially rotates, and the bending tube by non-soft materials, and then have and to bear rotation at a high speed, not easy fracture and durable characteristic.
