The protrusion 322a protrudes from the outer surface of the upper body 320 adjacent to the protrusion 322a, And a depression 322b engaging with the injection housing protrusion 511 formed on the outer side surface of the injection housing 510 is formed on the inner side surface.

An injection unit locking protrusion 321b for preventing the rear end of the injection housing 510 from moving rearward is formed on the inner surface of the upper body 320 in a stepped manner.

The elastic member mounting portion 330 includes a hollow pillar member for forming an inner space in which one end of the elastic member 440 provided in the injection hole opening and closing unit 400 is received.

The second inner housing 120 includes a first guide guide groove 128a corresponding to the first button guide 311 and a protruding housing guide groove 121 for guiding the upward and downward movement of the protruding housing 322. [ And a suction pipe through-hole 123 through which the pump suction pipe 220 of the pump unit passes.

The first guide guide groove 128a is formed by a first protrusion 127a and a second protrusion 127b protruding from the inner surface of the second inner housing 120 at a predetermined interval.

A first stopper 125a and a second stopper 125b are protruded from the inner side surface of the second inner housing 120 to prevent the button unit 300 from being rotated over a predetermined angle.

As a result, the protruding housing 322 can be manipulated to move out of the protruding housing guide groove 121, so that when the spray device is not used, the button unit 300 It can be prevented from being depressed.

The injection unit 500 includes an injection nozzle unit 520 having an injection hole 521 through which the fluid is injected and a rear region extending from the injection nozzle unit 520, And a flow path forming block 530 extending rearward from a portion of the front inner surface of the injection housing 510. The flow path forming block 530 may be formed of a synthetic resin.

The injection hole 521 is disposed at the center of the injection nozzle unit 520 and the injection nozzle unit 520 is inclined so that the fluid can be diffused forwardly with respect to the injection hole 521.

A second space S2 communicating with the first space S1 and a third space S3 communicating with the injection hole 521 are formed in the injection housing 510. [ A fluid inflow groove 513 communicating the first space S1 and the second space S2 is formed in the inner surface of the injection housing 510. [

A spray housing protrusion 511 for fitting the upper body 320 of the button unit protrudes from the outer surface of the injection housing 510.

An opening / closing unit engaging protrusion 515 on which the injection hole opening / closing unit 400 is seated is formed on the inner surface of the injection housing 510 in a stepped manner. The second space S2 is formed in front of the opening / closing unit engaging jaw 515 and the end 513a of the fluid inlet groove is disposed forward of the opening / closing unit engaging jaw 515.

[

The sliding block 410 is moved backward by only a small amount of fluid introduced into the empty space between the outer surface of the protrusion block 420 and the inner surface of the injection housing 510, The fluid can be efficiently sprayed even though the amount of the fluid flowing into the first space S1 by the pump unit 200 is small.

As the sliding block 410 is pushed backward, the injection hole opening / closing block 430 is simultaneously pushed back while opening the injection hole 521, The first injection path 531 and the second injection path 533 are also opened so that the second space S2 and the third space S3 communicate with each other.

Although the injection hole opening / closing block 430 may completely exit from the third space S3, a part of the injection hole opening / closing block 430 may be present in the third space S3, The front region of the block 430 may be moved backward by a certain distance from the injection hole 521. [

When the fluid flows into the third space S3, the fluid is inclined along the inner wall of the flow path forming block 530, so that the fluid flows through the injection hole 521 while forming a cyclone- And is sprayed outside.

As a result, the fluid exits the injection hole 521 while forming a cyclone-type flow path, so that the fluid can be efficiently sprayed in a mist form.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention as claimed in the claims. And such variations are within the scope of the present invention.
