Embodiment: referring to Fig. 1 to Fig. 6: spray gun, including shell 1, the lower end of shell 1 form handle portion 4, set in handle portion 4 There are power supply 5 and the pump housing 3, the front end of handle portion 4 is equipped with button switch 6, and power supply 5 is connect by button switch 6 with the pump housing 3；Pump Body 3 is connected with water inlet pipe 31, and shell 1 is stretched out in one end of water inlet pipe 31, and the middle part of shell 1 is equipped with spool 2, the water inlet end of spool 2 It is connect with the water outlet of the pump housing 3, spool 2 is equipped with control button, and shell 1 is stretched out in one end of control button, and the upper end of shell 1 is equipped with The inner end of sparge pipe 9, sparge pipe 9 is connect by converting interface 8 with the water outlet of spool 2.Converting interface 8 can be L-shaped two-way etc..

The technical program is at work, it is only necessary to connect the water inlet pipe 31 of the pump housing 3 with water source by pipeline, then open Spool 2 is sprayed water by the operation of button switch 6, and power supply 5 is powered the pump housing 3 first, and the pump housing 3 is drawn water by pipeline, Then water is transmitted to by drainpipe 32 by spool 2, and is externally sprayed by drainpipe 32.The technical program circuit in order to prevent Failure causes control button short circuit to cause to spray water always, is provided with spool 2, can control by the control button operation of spool 2 In the energized state, if externally water spray plays the role of safeguard protection.The spray gun is in use, non-without storing water Trip player is often facilitated to use.

Further, the pump housing 3 includes pump case, and pump case includes upper pump case 34 and lower pump case 35, the bottom of lower pump case 35 Equipped with bottom plate, the lower end of lower pump case 35 extends downwardly out sheath body 36, is socketed with motor 37 in sheath body 36, and the one of machine shaft 371 End is protruded into lower pump case 35 across bottom plate, and the end of machine shaft 371 is connected with driving gear (being not drawn into figure), the bottom Plate is connected with jackshaft, and jackshaft is socketed with in-line gears 39, and the in-line gears 39 include intermediate gear A391 and center tooth B392 is taken turns, intermediate gear A391 is engaged with driving gear；The middle part of the upper pump case 34 is equipped with fixed plate 317, and fixed plate 317 connects It is connected to transmission shaft 314, the lower end of transmission shaft 314 passes through fixed plate 317 and is connected with driven gear 38, driven gear 38 and centre Gear B 392 engages, and a cavity 315, the arc-shaped setting in the two sides of cavity 315 and two are equipped in the middle part of the upper surface of fixed plate 317 Side is respectively equipped with intermeshing two expelling water gears 311,313, and one of expelling water gear 311 is connect with transmission shaft 314, Gu Fixed board 317 is connected with fixing axle 310, another expelling water gear 313 and fixing axle 310 are socketed；In motion process, expelling water gear 311,313 increment is abutted with the arc shaped inside face of cavity 315, and the both ends at 315 middle part of cavity are respectively equipped with into 316 He of water space Drainage space 312, water inlet space 316, drainage space 312 are connected separately with water inlet pipe 31 and drainpipe 32.

Preferably, upper pump case 34 is connected with lid 33, and the drainpipe 32 is set to lid 33.

At work, motor 37 rotates and machine shaft 371 is driven to rotate the pump housing 3；Machine shaft 371 drives driving gear Rotation, driving gear pass through the transmission of in-line gears 39, and driven gear 38 is driven to rotate, and driven gear 38 passes through transmission shaft 314 Intermeshing two expelling water gears 311,313 are driven to rotate, to complete to water-driven.In the process, in-line gears 39 In intermediate gear A391, intermediate gear B392 can play the role of deceleration, while also facilitating adjustment transmission shaft 314 and motor The position of shaft 371；When draining, the technical program does not use the structure of turbo blade, but uses two and nibble The structure of gear is closed, so that it is more convenient to draw water, specific reason are as follows: when drawing water rigid beginning, if using turbine blade arrangement, After turbo blade rotation, since revolving speed is relatively low, when blade postpones forward air, intaking, space 316 forms of short duration negative pressure, The air supplement that the negative pressure is refluxed soon, is difficult to form higher negative pressure in the water inlet space 316 of cavity 315, and then very Hardly possible water suction；And after using two meshing gear structures, after two expelling water gears 311,313 rotate, by the sky in space 316 of intaking Gas is gradually squeezed to drainage space 312, it is easy to negative pressure is formed in water inlet space 316, due to increment and the cavity 315 of gear Medial surface abuts, and causes the air of hydrospace out that cannot be back to substantially into water space 316, forms negative pressure in water inlet space 316 Afterwards, the water at water source enters water inlet space 316 under atmospheric pressure, then passes to out hydrospace.For convenience of maintenance, the technical program is set Lid 33 is set.

Further, the spool 2 includes tube body 24 open at one end, and the two sides of tube body 24, which are connected separately with, has height The inlet tube 23 and outlet tube 25 of difference, control button are core, and the middle part of core is equipped with for by inlet tube 23 and outlet tube 25 The interconnecting part 21 of connection, the outer diameter of interconnecting part 21 are less than the internal diameter of tube body 24, and tube body 24 is stretched out in one end of core.

The technical program is controlled using simple core, when the both ends of the interconnecting part 21 of core are located at inlet tube 23 with the outer end of outlet tube 25 when, inlet tube 23 is connected to outlet tube 25；When interconnecting part 21 and inlet tube 23 or outlet tube 25 it When one or more dislocation, inlet tube 23, outlet tube 25 are blocked.In specific setting, when core can be fully inserted into tube body 24, It is designed to that inlet tube 23 is connected to outlet tube 25, can be convenient operation in this way.

Further, the core is equipped with operation portion 29, and operation portion 29 stretches out tube body 24, and the outer diameter of operation portion 29 is less than The internal diameter of tube body 24 is equipped with limiting section 210 between operation portion 29 and interconnecting part 21, limiting section 210 and tube body 24 are socketed, the pipe The open end of body 24 is connected with sealing cover 22, and sealing cover 22 is equipped with the through-hole matched with operation portion 29.

After limiting section 210 and sealing cover 22 are set, the activity of core can be limited, it is avoided to remove tube body 24. It is easy to disassemble simultaneously.

Further, the both ends of interconnecting part 21 are respectively equipped with sealing ring 26.

After sealing ring 26 is set, the leakproofness of spool 2 can be increased, when the end of inlet tube 23, outlet tube 25 does not have position When in interconnecting part 21, by sealing ring 26, its water route is blocked.

Further, spring 27 is equipped between core and the sealed end of tube body 24, and sealed end is equipped with and is used for retaining spring 27 positioning column 28, spring 27 are placed on outside positioning column 28.

After spring 27 is arranged, under the original thrust of spring 27, limiting section 210 and the sealing cover 22 of core offset core, into Liquid pipe 23, outlet tube 25 are in blocking state.When needing to open, core is internally pressed, until inlet tube 23, outlet tube 25 connections.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
