Description

The scalable antomobile sprayer of backpack

Technical field

The utility model relates to sprayer, refers in particular to spray the antomobile sprayer of usefulness with carrying out sterilizing.

Background technology

When pesticide spraying, environment, object sterilization, all need use sprayer.All use hand sprayer in the past mostly, relatively expend muscle power.The sprayer that uses on the market at present is antomobile sprayer mostly, through pump soup is sprayed away through jet pipe.Though sprayer has been realized automatic sprinkling; But when at the higher object of spraying altitude, because the length of its jet pipe can not extend automatically, the angle of inclination of nozzle can not be regulated; Zone near the jet pipe below is difficult to be sprayed onto, and therefore in practical application, has brought very big inconvenience.

Summary of the invention

The utility model technical problem to be solved provides a kind of sprayer, and its jet pipe can stretch, and nozzle can carry out level 360 to be regulated, and can also vertically regulate its angle of inclination, more convenient sprinkling.

For solving the problems of the technologies described above; The technical scheme that the utility model provides is the scalable antomobile sprayer of a kind of backpack; It comprises casing, pump, jet pipe and shower nozzle; Said casing is communicated with the inlet of said pump, and said jet pipe one end is communicated with the liquid outlet of said pump, and its other end is communicated with said shower nozzle; Said shower nozzle comprises hollow duct and is installed in the nozzle of said hollow duct one end; It is characterized in that said jet pipe is made up of the pipe of two scalable sockets at least, pipe one end near said casing is communicated with the liquid outlet of said pump, and pipe one end away from said casing is communicated with said shower nozzle; Each socket place at said pipe is respectively arranged with nut locking device; Said nut locking device comprises sealing ring, centring ring, compacting ring and nut check cover; Said sealing ring, centring ring and compacting ring are set in the periphery of the little pipe of said socket place diameter successively; Said sealing ring the distolateral of the big pipe of said socket place diameter of conflicting; Outer end wall at the big pipe of said socket place diameter offers screw thread, and said nut check cover is set in periphery and the screw lock of said sealing ring, centring ring and compacting ring on the outer end wall of the big pipe of said socket place diameter; The said end wall that has the arc opening of the perforation of offering away from pipe one end of said casing; Said shower nozzle is the universal spherical shower nozzle, and said universal spherical shower nozzle is connected with the spherical pair structure with said arc opening.

Pipe one end big at the said diameter of the socket place that is positioned at said pipe has inside flange, and pipe one end that said diameter is little has outside flange; The outside flange of pipe one end that said diameter is little is positioned at the big pipe of said diameter, and the external diameter of its outside flange is greater than the internal diameter of the inside flange of the big pipe of said diameter.

The end that said universal spherical shower nozzle is positioned at the hollow duct at said arc opening place is horn-like.

The utility model jet pipe realize freely stretching through the several tubes socket, through the universal spherical shower nozzle, realized that nozzle horizontal direction 360 is spent freely to rotate that vertical direction also can tilt at a certain angle.This structure has enlarged spread of spray, has avoided the dead angle, has made things convenient for operation.

The specific embodiment

To technique scheme, lift a preferred embodiment at present and combine graphic specifying.Referring to Fig. 1, the backpack automatically retractable sprayer of the utility model, it comprises casing, pump, jet pipe and shower nozzle, wherein.

Casing is used for holding soup, and the inlet of pump is communicated with casing, and the liquid outlet of pump is communicated with jet pipe, through pump soup is delivered in the jet pipe, through with shower nozzle that jet pipe is communicated with on the nozzles spray soup, realize medicine liquid spray, to the sterilization of object.Because casing, pump, its syndeton of jet pipe are prior art, therefore repeat no more at this.Emphatically telescopic jet pipe and nozzle structure are described in the present embodiment.

Jet pipe comprises several pipes that connect together compositions.Adopt three pipe sockets to form jet pipe in the present embodiment, these three pipes are respectively parent tube 1, middle pipe 2 and go up pipe 3.One end of parent tube 1 is connected with the liquid outlet of pump, and its other end port has to projecting inward inner edge 11, and the inner face of inner edge 11 is provided with sealing ring 12.

Middle pipe 2, the internal diameter of its external diameter and inner edge 11 is complementary, and the one of which end has the outer rim 21 of outside protrusion, and the other end has to projecting inward inner edge 22, and the inner face of inner edge 22 is provided with sealing ring.The end that middle pipe 2 has outer rim 21 is socketed in the parent tube 1, and the external diameter of outer rim 21 is identical with the internal diameter of parent tube 1.In the middle of pipe 2 during along parent tube 1 elongation, just in time the conflict inner edge 11 of parent tube of its outer rim 21 carries out in the screens sealing restriction pipe 2 and from parent tube 1, deviates from.

Last pipe 3, its external diameter is complementary with the internal diameter of the inner edge 22 of middle pipe 2, and the one of which end has the outer rim 31 of outside protrusion, and the other end is an end wall 32, on end wall 32, offers trumpet-shaped arc opening 33.In the pipe 2, the internal diameter of the external diameter of outer rim 31 and middle pipe 2 was complementary during the end that last pipe 3 has outer rim 31 was socketed in.When last pipe 3 during along 2 elongations of middle pipe, just in time the conflict inner edge 22 of parent tube of its outer rim 31 carries out screens sealing restriction and goes up pipe 3 and therefrom manage in 2.At the detachable universal spherical shower nozzle 4 that is equipped with of the front end of end wall 32, between universal spherical shower nozzle 4 and end wall 32, be provided with the O RunddichtringO.The spherical portion of universal spherical shower nozzle 4 is positioned partially in the arc opening 33, and suits with the curved end of arc opening 33, also is that the spherical part of universal spherical shower nozzle 4 is connected with the spherical pair mode with arc opening 33.The opening that universal spherical shower nozzle 4 inner hollow duct 41 are positioned at arc opening 33 1 ends is horn-like opening, and horn-like hatch bore diameter is positioned at the hatch bore diameter of pipe 3 one sides greater than arc opening 33.When universal spherical shower nozzle 4 tilt to rotate at a certain angle, horn-like opening can guarantee to get into swimmingly in the hollow duct and through nozzle 42 ejections of shower nozzle 4 through the soups that last pipe 3 flows.

For the parent tube that guarantees to connect together, middle pipe with go up that pipe is stable does not vacillate now to the left, now to the right and sealing property, be provided with sealing-locking device at the pipe belled position.Sealing-locking device comprises sealing ring 51, centring ring 52, compacting ring 53 and locking nut cover 54, and the external diameter of sealing ring 51, centring ring 52 and compacting ring 53 is identical with the external diameter of parent tube 1.Is example with parent tube 1 with middle pipe 2 socket places.On middle pipe 2 periphery walls, be arranged with sealing ring 51, centring ring 52, compacting ring 53 successively, wherein sealing ring 51 is positioned at end one side of parent tube 1, and compacting ring 53 is conical away from centring ring 52 1 ends, and compacting ring 53 can be made up of several wedges.

Nut check is overlapped the shape that 54 cavity shapes and sealing ring, centring ring and compacting ring combine and is complementary; Nut check cover 54 is set in the outside of sealing ring, centring ring and compacting ring; End periphery in that parent tube 1 contacts with sealing ring is provided with screw thread, and nut check cover 54 passes through screw-threaded coupling on parent tube 1.Through the nut check cover pipe socket place is carried out fit sealing.In the time of need pipe being stretched out,, carry out fastening after having stretched again as long as unclamp the nut check cover.
