Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spray apparatus, and more particularly to a spray apparatus for injecting and supplying a chemical such as a lubricating oil and a cleaning agent to a desired location inside a complicated mechanical apparatus.
[0002]
[Prior art]
In an evaporator of a car air conditioner, mold and bacteria are likely to propagate due to moisture generated by heat exchange, and a strange odor may be generated. The applicants invented an agent for washing the evaporator to remove mold and bacteria, and to prevent odors derived from it for a long period of time, and filed a patent application as Japanese Patent Application No. 7-293444. Yes.
[0003]
[Problems to be solved by the invention]
However, the car air conditioner has a complicated structure, and the car air conditioner has to be disassembled in order to thoroughly clean the internal evaporator. The car air conditioner has an opening for work, and it is possible to spray and wash the medicine from there, but it is difficult to spread the medicine to the inside of the evaporator that can not be seen through the opening Met.
[0004]
It is an object of the present invention to provide a spray device for cleaning and removing mold and bacteria by spraying a cleaning agent directly on an evaporator inside the car air conditioner having such a complicated structure. is there.
[0005]
[Means for Solving the Problems]
Thus, the present invention provides a flexible plastic coating on the surface of a plastically deformable metal tube at the tip of the air gun, which can be bent while maintaining the air flow and can maintain its shape. Attach the trachea, insert the base part into the container containing the drug, and bring the tip of the liquid supply pipe made of a flexible plastic tube to the bottom of the container along the air supply pipe, the air supply pipe and the liquid supply pipe The tip of is connected to a spray head formed with two or more injection ports facing sideways.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a spray apparatus 1 according to the present invention. Reference numeral 2 denotes an air gun, which is supplied with compressed air from an air compressor (not shown) via an air hose 3 connected to a tail portion. Compressed air is ejected from the tube tip 5 while being controlled.
[0008]
An air supply pipe 6 is attached to the tube tip 5. The air supply pipe 6 can be bent while ensuring air circulation therein, and has a rigidity sufficient to maintain a desired bent state, and is made of a plastically deformable metal such as copper. The tube is preferably formed by coating a soft plastic such as polyethylene, polypropylene or nylon.
[0009]
The length of the air supply tube 6 is such that it can be easily handled by gripping the air gun 2, and the tip of the air supply tube 6 can be inserted into the inside of the mechanical device to reach the position where the medicine is to be ejected. The length is approximately 20 to 50 cm, although it varies depending on the internal mechanism of the target mechanical device and the position where the medicine is to be ejected.
[0010]
Reference numeral 7 denotes a liquid feeding tube made of a flexible plastic tube. The base portion is inserted into a container 8 containing a medicine, and the terminal reaches the bottom of the container 8. The distal end portion of the liquid supply pipe 7 is stopped by a clip 9 along the air supply pipe 6, and there is a margin from the base of the air supply pipe 6 to the container 8.
[0011]
The length of the liquid supply pipe 7 is preferably enough to allow the air gun 2 and the air supply pipe 6 to be handled and operated with the container 8 placed at an appropriate place. It is preferable to have a margin of about 1 to 2 m from the base part to the container 8.
[0012]
A spray head 10 is attached to the tips of the air supply pipe 6 and the liquid supply pipe 7. The spray head 10 has a cylindrical main body 11 which is connected to the air supply pipe 6 and the liquid supply pipe 7, respectively, and has a ventilation hole 12 and a liquid passage hole 13 formed in the axial direction. A mouth 14 is formed. In addition, the injection port 14 is not restricted to two, One may be sufficient, and three or more may be provided.
[0013]
The injection port 14 communicates with the vent hole 12 at the bottom portion and the liquid passage hole 13 at the intermediate portion, and air sent from the air supply pipe 6 is ejected from the injection port 14 through the vent hole 12. At the same time, the drug is sucked from the liquid passage hole 13 by the suction force generated by the jetted air flow, and jetted from the jet port 14 together with the air flow.
[0014]
[Action]
In the present invention, when the air hose 3 is connected to an air compressor and the trigger 4 is operated, compressed air is sent out from the tube tip 5 of the air gun 2, which passes through the air supply pipe 6 and vent holes 12 in the spray head 10. And is ejected from the ejection port 14.
[0015]
On the other hand, the liquid passage hole 13 is depressurized by the air ejected from the ejection port 14, and the medicine in the container 8 is sucked into the liquid feeding pipe 7 by the suction force and passes through the liquid passage hole 13 of the spray head 10. And mixed with the air supplied from the vent hole 12 and sprayed from the injection port 14.
[0016]
Thus, the air supply pipe 6 is connected to the tube tip 5 of the air gun 2, and the spray head 10 is attached to the tip of the air supply pipe 6. Therefore, the spray head 10 is inserted into the back of a mechanical device such as a car air conditioner and the desired It is possible to spray chemicals such as lubricants and cleaning agents at the locations.
[0017]
Further, since the spray head 10 is attached to the tips of the air supply pipe 6 and the liquid supply pipe 7, it can be inserted from a narrow opening of the mechanical device, and the air supply pipe 6 is bent so that it cannot be seen from the opening. It is possible to insert the spray head 10 to the position.
[0018]
And since the injection port 14 is provided in the side surface of the spray head 10, a chemical | medical agent can be sprayed to the side position which cannot be seen through the opening part inside a mechanical apparatus, and can be efficiently distributed.
[0019]
【The invention's effect】
Therefore, according to the present invention, the air supply pipe 6 can be inserted into a complicated mechanical device such as an evaporator of a car air conditioner, and a chemical such as a cleaning agent can be sprayed and supplied to a desired location appropriately. . Further, since the container 8 is separated from the air gun 2, the air gun 2 can be easily handled in a narrow place, and a large amount of medicine can be accommodated in the container 8, so that workability is good.
