Description

Atomizing spray gun

Technical Field

The utility model relates to a medicine, chemical industry, food equipment field especially relate to an atomizing spray gun.

Background

Among medical instruments, containers such as syringes and vials are frequently used. For example, when the syringe is used, medical staff injects liquid medicine into a human body, so that dry friction between a piston of the syringe and a glass needle tube is reduced by ensuring sterility and smoothly injecting, and lubricating oil such as silicone oil is usually sprayed on the glass needle tube. The atomizing spray gun used in the current market comprises an oil pipe, an inner pipe with the inner diameter d of 0MM < d ≦ 0.6MM, an outer pipe and a gas source pipe, wherein the inner pipe and the outer pipe are coaxially arranged, the outer pipe is wrapped on the periphery of the inner pipe, a gap is formed between the outlet end face of the inner pipe and the outlet end face of the outer pipe to form a mixing area, the outer pipe is communicated with the gas source pipe, and the lengths of the outer pipe and the inner pipe are larger than 70 MM. The installation sequence of the atomizing spray gun is as follows: penetrate the inner tube from the one end of outer tube, predetermine the distance between inner tube terminal surface and the outer tube terminal surface, form the good mixed district of atomization effect, then fix the outer tube on oil pipe through threaded connection, at last with the air supply union coupling on the outer tube. The atomization spray gun mixes the air source in the air source pipe and the lubricating oil in the inner pipe into atomized lubricating oil in a mixing area, has simple structure and good atomization effect, but because the length difference of the inner pipe relative to the diameter of the inner pipe is more than 100 times, the inner pipe is extremely thin and long, if viscous lubricating oil is used, the inner pipe is easy to be unsmooth, and when the atomization spray gun needs to be cleaned or maintained, the elongated inner pipe is taken out from the elongated outer pipe, so the operation difficulty is high; and when the spray gun is installed, the slender inner pipe is easy to bend in the inner cavity of the outer pipe. Usually the spray gun is fixed on the workstation support, must dismantle the spray gun from the workstation support, when the spray gun spraying simultaneously, shower nozzle outer tube export is perpendicular up, the partial lubricating oil of complete atomizing flows back along shower nozzle outer tube inner wall not in the mixed zone, including impurity in the air supply can bond on the outer tube inner wall together with lubricating oil, influence the gas circulation, atomization effect is poor, if when wanting to wash the outer tube inner chamber, it touches elongated inner tube easily to dismantle the outer tube, the operation is arduous, it is extremely inconvenient, also consuming time.

Disclosure of Invention

The utility model aims to solve the technical problem that an installation and maintenance are convenient, labour saving and time saving's atomizing spray gun is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides an atomizing spray gun, includes oil pipe, inner tube, outer tube and air supply pipe, inner tube sealing connection be in oil pipe on, the outer pipe box establish the inner tube on, its characterized in that the outer tube include shower nozzle outer tube and connection outer tube, shower nozzle outer tube detachably connect the one end of connection outer tube, the other end of connection outer tube connect oil pipe on, the air supply pipe with connection outer tube intercommunication.

Furthermore, an air guide part is arranged between the inner pipe and the nozzle outer pipe in a sealing mode, a plurality of spiral lines are arranged on the air guide part, a thread groove is formed between every two adjacent spiral lines, and the thread grooves are used for being communicated with the air source pipe. Further improve gas flow even, make full use of thread groove as the gas passage, effectively reduced process flow.

Further, the air guide piece is welded on the inner pipe. Adopt welding mode to make air guide and inner tube even as an organic whole, when dismantling the shower nozzle outer tube and carry out maintenance, air guide can not drop, also exempts the location.

Furthermore, a fixing part is arranged at one end of the inner pipe close to the oil pipe, and the fixing part is fixed with the inner pipe in a welding mode. The slender inner tube is generally difficult to take, the fixing part is welded on the slender inner tube, and when the fixing part is maintained, the fixing part is more convenient to take relative to the slender inner tube, and the disassembly efficiency is improved. The oil pipe can be protected by using the fixing piece, and the oil pipe is conveniently fixed on the workbench bracket; the connecting outer pipe and the oil pipe are both tubular objects, a threaded joint mode is adopted, the connection is convenient, no pollution is caused during connection, and the structure is simple.

Furthermore, the oil pipe is provided with a fixing piece, and the connecting outer pipe and the fixing piece are fixed on the oil pipe in a threaded joint mode. The air source pipe and the spray head outer pipe are both tubular objects, a threaded joint mode is adopted, connection is fast, pollution is avoided during connection, and operation is simple.

Furthermore, the gas source pipe is connected to the connecting outer pipe in a threaded joint mode.

Furthermore, the inner diameter D of the outer pipe of the spray head is 1.00mm < D ≦ 1.5 mm.

Compared with the prior art, the utility model has the advantages of the outer tube includes the shower nozzle outer tube and connects the outer tube, is divided into two with integrative outer tube, and shower nozzle outer tube detachably connects on connecting the outer tube. When impurities in the air source and lubricating oil are bonded on the inner wall of the outer pipe and need to be cleaned or maintained, the outer pipe of the spray nozzle is only required to be detached from one end connected with the outer pipe, and the exposed outer wall of the inner pipe or the inner wall of the outer pipe of the spray nozzle is directly cleaned or maintained respectively; when the inner pipe is obstructed due to viscous lubricating oil, the nozzle outer pipe is taken down firstly, then the connecting outer pipe is taken down, and finally the inner pipe is separated from the oil pipe, because the length of the nozzle outer pipe and the connecting outer pipe is greatly shortened compared with the length of the original outer pipe, the nozzle outer pipe and the connecting outer pipe are dismounted one by one in a segmented manner, the bending probability of the inner pipe in the nozzle outer pipe and the connecting outer pipe is greatly reduced, the oil pipe is not required to be dismounted from the workbench bracket, namely when the spray gun is mounted, the inner pipe is connected on the oil pipe in a sealing way, the connecting outer pipe is sleeved on the oil pipe from one end of the inner pipe and is arranged on the oil pipe, if the exposed inner pipe is accidentally bent by the connecting outer pipe, can be corrected in time, and finally the outer pipe of the spray head is connected with the outer pipe, so that the outer pipe is arranged in a sectional way, the installation, the maintenance and the repair are convenient, the time and the labor are saved, the operation is simple, and the bending rate of the inner pipe is greatly reduced.
