Description

  The present invention relates to a two-component mixed sprayer, and more particularly to a two-component mixed sprayer in which a two-component mixed sprayer is mounted on a spray gun in a cartridge manner and sprayed by operating a trigger.

  A spray head in which two spray nozzles are arranged in parallel, two syringe-like cylindrical containers that are inserted into the spray head and separately store two different types of liquids, and plungers that are inserted into the cylindrical portion of each cylindrical container A two-component simultaneous sprayer equipped with a plunger restricting means operated by a trigger is conventionally known (see, for example, Patent Document 1).

The conventional sprayer described in Patent Document 1 is configured such that each syringe-like cylindrical container is individually engaged with two spray nozzles provided in the spray head and is fitted into the spray head. Could not be mixed and sprayed.
In addition, there is a problem that the pressure storage function cannot be provided only by sending the liquid stored in the two syringe-like cylindrical containers to the spray nozzle by the plunger operation and spraying the liquid.
Furthermore, the two cylindrical containers and the plunger are mounted in separate and separate housings, and there is a problem that the structure is complicated.

  As a sprayer, a trigger type sprayer in which two types of liquids are mixed and sprayed is also known (see, for example, Patent Document 2).

The sprayer described in Patent Document 2 sprays a mixed liquid, but there is a problem that the structure cannot be downsized and sprayed in a narrow range.

Next, the state of use and effects of the two-component mixing sprayer of the present invention will be described.
The two-component mixing sprayer of the present invention is used as a sprayer for chemicals, cosmetics, and other liquid contents.

The assembly of the two-component mixing sprayer will be described.
First, as for the sprayer main body A, as shown in FIG. 3, the resin spring members Ad1 and Ad2 are inserted into the cylindrical bodies Aa1 and Aa2 from below the container main body Aa, and then the valve members Ac1 and Ac2 are inserted.
Next, the nozzle member Ab is mounted on the upper part of the container main body Aa.
In this state, after storing different liquids in the cylindrical bodies Aa1 and Aa2, the piston members Ae1 and Ae2 are inserted, and the lid member Af is attached from below the container body Aa, and the sprayer is closed. The main body A is completely filled with the content liquid.

In the state before use, since the resin spring members Ad1, Ad2 are in a state where the force is released, the valve members Ac1, Ac2 are retracted by the elasticity of the resin spring members Ad1, Ad2. The holes 32a and 32b are closed.
Moreover, since the lid member Af is attached to the container main body Aa, the piston members Ae1 and Ae2 are prevented from being detached from the container main body Aa.

Next, as for the spray gun B, as shown in FIG. 4, the mounting cylinder member Bb is attached to the fitting portion 52 of the trigger member Ba through the engagement hole 60 of the mounting plate 56.
In this state, the assembly of the spray gun B is completed by fitting the sliding plate 53 of the trigger member Ba into the guide hole 69 of the gun body Bc.

About the assembly of a two-component mixing sprayer, as shown in FIG. 8, the mounting cylinder member Bb of the spray gun B is tilted forward.
Next, when the sprayer main body A is inserted from the nozzle member Ab side into the cylindrical portion 55 of the mounting cylinder member Bb, the outer periphery of the casing 10 of the nozzle member Ab is engaged with the opening 59 of the mounting cylinder member Bb. The sprayer main body A is fixed in the cylinder part 55 of the attachment cylinder member Bb.
When the front of the mounting cylinder member Bb to which the sprayer main body A is fixed is returned to the original position, the assembly of the two-component mixed sprayer is completed.

When spraying, the nozzle member Ab is directed in the desired spray direction, the trigger 51 of the trigger member Ba of the spray gun B and the grip 66 of the gun body Bc are gripped, and the trigger member Ba is pulled, so that the mounting cylinder member Bb The sprayer main body A fixed to the rear moves.
As the sprayer main body A moves rearward, the operating rods 76a and 76b of the pressing portion 67 of the gun main body Bc are inserted into the operating rod support portions 38a and 38b of the piston members Ae1 and Ae2 in the container main body Aa. The operating rods 76a and 76b press the piston members Ae1 and Ae2.

As the piston members Ae1 and Ae2 move forward, the pressure in the cylindrical bodies Aa1 and Aa2 rises, and pressure is applied to the concave pressure receiving surfaces 29a and 29b of the valve members Ac1 and Ac2, and when a predetermined pressure is reached, the resin spring member Ad1 and By compressing Ad2, the valve members Ac1 and Ac2 move forward.
At that time, the air in the cylindrical bodies Aa1 and Aa2 passes through the air holes 7a and 7b, so that the forward movement of the pressure receiving piston bodies 25a and 25b is not hindered.

Along with this advancement, the valve bodies 26a, 26b move forward by sliding on the valve holes 4a, 4b of the container body Aa, and open the discharge holes 32a, 32b.
The liquid discharged from the discharge holes 32a and 32b is injected into the mixing chamber 12 of the nozzle member Ab from the flow paths 5a and 5b and mixed, and then flows through the flow path 14 into the nozzle tip 18 to form an annular shape. The liquid is further mixed by the flow path 21 and the spin groove 20, and the mixed liquid is mixed and sprayed from the ejection port 19.

  To stop spraying, when the trigger member Ba is stopped, the pressing force applied to the piston members Ae1 and Ae2 is released, and the valve members Ac1 and Ac2 are restored by the resin spring members Ad1 and Ad2. , Naturally retreated to its original position.

As the valve members Ac1 and Ac2 are retracted, the discharge holes 32a and 32b are automatically and instantaneously closed, so that the liquid can be surely confined, spraying is stopped, and the valve bodies 26a and 26b are retracted. As a result, the flow paths 5a, 5b of the container main body Aa and the mixing chamber 12, the flow path 14, and the nozzle tip 18 in the nozzle member Ab are in a reduced pressure state, so that the liquid that was about to be ejected is pulled back into the mixing chamber 12. A suction force will be generated.
That is, the flow paths 5a and 5b and the mixing chamber 12 also function as a suction chamber, and the effect of preventing liquid dripping from the ejection port can be further increased.

When spraying is stopped, the piston members Ae1 and Ae2 are maintained at the stop position, and the trigger member Ba of the spray gun B is also maintained at the stop position.
When spraying again, when the trigger member Ba is further pulled, the sprayer main body A moves rearward and is mixed and sprayed as described above.
The liquid spray amount is determined according to the pulling length of the trigger member Ba and can be freely adjusted by the operator.

  In the above embodiment, two cylindrical bodies are connected as the container main body. However, even with a single cylindrical body, dripping can be prevented, so a compact pressure-accumulating sprayer using one cylindrical container is used. May be.

  In addition, a resin spring member having a specific shape is used as the spring member, and there is an effect that there is no need for separation when disposing of the sprayer. However, the spring is a metal coil spring or a required elastic member. It may be an elastic body having repellency, and is not limited to the examples.

   In the above embodiment, the valve member and the resin spring member are separately mounted in the cylindrical body of the container body. However, the spring member and the pressure receiving piston body of the valve member are integrated into the cylindrical body. It can also be installed.

Since the two-component mixing sprayer of the present invention is equipped with a pressure-accumulating mixing sprayer on a spray gun and can be operated with a trigger member, the operability is improved and can be widely used as a sprayer for mixing and spraying different types of liquids.
In particular, in the case of using an accumulator sprayer, dripping is prevented, so that the application can be further expanded.
