2. Description of the Related Art Conventionally, as a spray outlet of this kind of spray, there are a spray port of an injector provided on a spray can and a tip opening of a tube inserted into the spray port. Lightweight foreign matter is blown off by the ejection port from the spray.

[0003]

However, in such a spray outlet, there is a problem that dust and foreign matter which cannot be blown out by the blowing pressure remain. In addition, there is a problem in that the gas itself or the ejected matter, such as gas or liquid, is charged with static electricity by the blowing pressure, and foreign matter easily adheres to the target when the gas or liquid comes into contact. On the other hand, the treatment of such foreign matter is physically performed using another brush, but has the problem that it is troublesome twice. Therefore, there is a problem that foreign matter is easily attached again. In addition, there is a problem that static electricity on the surface of OA equipment or the like cannot be removed only by such ejected matter.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional product, and it is difficult to discharge static electricity to a gas or a liquid to be ejected, and to remove foreign matter or a gas or a liquid which is difficult to remove by the ejection of a gas or a liquid. It is another object of the present invention to provide a method for manufacturing a spray jet brush capable of removing static electricity.

[0005]

Means for Solving the Problems The invention according to the present application is:
A plurality of fiber members based on antistatic synthetic resin fibers are cut into arbitrary lengths and arranged in parallel to each other to form a substantially band-like body as a whole, and the band-like body serves as a spray outlet and becomes conductive. Is provided around the distal end of the tube while projecting in the longitudinal direction from the distal end of the tube, and electrically connects the fibrous member and the tube to each other. A method for manufacturing a brush for a spray nozzle, comprising: attaching a covering material for covering the strip so as not to be detached from the pipe unnecessarily; and grounding the pipe.

As means for arranging the fiber members in parallel, means for arranging the fiber members so that the fiber members are parallel to each other while allowing one end of the fiber members to be peeled off from the tape-like body, or banding the fiber members with an adhesive is used. And the like.

Means for extending the belt-like body made of the above-mentioned fiber member in the longitudinal direction from the tip end of the pipe serving as the spray outlet while surrounding the tip end of the pipe is to allow the tape-like body to be peeled off. Means include winding the arranged fiber members around the distal end of the tube and peeling off the tape-shaped body.

As means for coating the coating material so as not to be detached from the pipe unnecessarily, means for laminating an adhesive or an adhesive on the coating material to fix the above-mentioned band-like material, or means for applying an adhesive or adhesive to the band-like material can be used. And then winding the coating material.

The brush for a spray outlet manufactured by the manufacturing method according to the present invention includes a tube in which the inside of the spray for ejecting the container is communicated with the inner wall, and a tip of the tube serving as the nozzle for the container. While being disposed on the outer periphery, the fiber member includes a plurality of fiber members disposed along the longitudinal direction of the tube, and a coating material disposed on the outer periphery of the tube and the fiber member. An antistatic synthetic resin fiber, wherein the tube is a conductor and grounded, and the fiber member and the tube are electrically connected.

[0010] In order to spray the spray contents evenly, it is preferable to arrange the spray outlet brush so as not to impede the outlet itself.
Also in the present invention, it is attached to the outer peripheral surface of the tube forming the spout.

The above-mentioned fiber member constituting the brush itself has an elastic force capable of removing foreign substances adhering to the surface of the OA equipment, the inside thereof, a printed circuit board, and the like, and is conventionally known in order to remove static electricity and prevent it from being carried. The antistatic fiber and antistatic fiber of the present invention can be used.
Fiber like No. is good. If antistatic fibers or antistatic fibers are used, it is needless to say that natural fibers or synthetic fibers having antistatic properties may be mixed. Examples of these fibers include pigs, sheep, horses, and goats as natural fibers, and acrylic resin, nylon,
There is a simple substance or a composite such as polyvinyl chloride, polypropylene, polyethylene terephthalate, and polybutylene terephthalate. Needless to say, fibers of these materials may be mixed.

[0012] Further, the tube holding the above is a conductor and grounded, and the fiber member and the tube are electrically connected to each other, so that static electricity which is easily carried on the surface of the OA equipment, the inside thereof, a printed circuit board, or the like is generated. Remove. In addition,
If the surface of the OA device or the inside thereof or a printed circuit board is swept with a fiber member having no antistatic property, static electricity is generated at an uncharged portion, but if such antistatic synthetic resin fiber is used, Such static electricity can be prevented from occurring.

The covering material can be appropriately selected as long as it has an effect of bundling the fiber members. For example, the covering material is made of a synthetic resin having one surface coated with an adhesive or a pressure-sensitive adhesive, or a metal such as an aluminum foil. There is a tape-shaped body made of paper or paper. Further, by covering the outer periphery of the coating material with a cover made of a synthetic resin, it is possible to make it hard to be damaged from the outside and to make it hard to damage the outside.

[0014] As the above-mentioned tube having a spray outlet, there can be used a tube having conductivity which has been conventionally used, and the rigidity required for these tubes is such that the portion holding the fiber member does not bend unnecessarily. I just need. In addition,
The reason why the material of the tube is a conductor is to release the electric charge of the fiber member, and it is needless to say that various metal tubes and resins having conductivity may be used.

[0015]

According to the method of the present invention for producing a spray outlet brush, a gas or liquid to be ejected is less likely to be charged with static electricity.
Manufactures a spray outlet brush that can remove foreign substances that are difficult to remove by jetting gas or liquid, as well as static electricity.
