Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the trigger spray device 1 according to an embodiment of the present invention.

As shown in FIGS. 2, 3, and 5, when the handle member 12 is pulled toward the housing 20, the piston 16 coupled to the main protrusion 18 opens the space of the inner groove 37. Compress.

The liquid stored in the inner groove 37 is moved to the second conduit 33 of the conduit member 35 through the connection hole 38.

A part of the liquid moved to the second conduit 33 moves downward along the second conduit 33 to move the first wing member 74 of the first valve part 70 downward.

The first wing member 74 of the first valve unit 70 which is moved downward is caught on the upper end of the first conduit 32 to block liquid from moving to the container 9 along the first conduit 32. .

The guide piece 62 is inserted into the insertion groove 78 provided between the first head member 76 to prevent rotation and shaking of the first valve portion 70, so that the first wing member 74 and the first blade member 74 The adhesiveness of the conduit 32 is improved.

The liquid confined to the lower movement of the second conduit 33 flows to the communication hole 47 along the third conduit 34 communicating with the upper side of the second conduit 33.

The liquid flowing into the communication hole 47 flips the second wing member 84 of the second valve portion 80 in the direction of the second body member 82 and moves in the direction of the nozzle portion 3 so that the trigger spray device 1 ) Is sprayed outward.

When the pressure generated while the piston 16 presses the inner groove 37 is less than the set pressure, the shape of the second wing member 84 is restored to its original shape, and the nozzle portion 3 through the third pipe 34. To block the flow of liquid to move.

On the other hand, when the negative pressure protrusion 19, which is moved together with the piston 16, is moved to the inside of the negative pressure groove 50, air into the space formed between the outer surface of the negative pressure protrusion 19 and the inner surface of the negative pressure groove 50. Is moved to the inside of the container 9 through the negative pressure hole 54 to prevent deformation of the container (9).

2, 4 and 5, when the handle member 12 is moved away from the housing portion 20 by the elastic force of the elastic member 14, the piston coupled to the main projection (18) ( As the 16 is moved outward, the space of the inner groove part 37 is expanded.

Since a vacuum pressure is generated inside the inner groove 37, the inner pressure of the inner groove 37 is lower than the inner pressure of the container 9 or the outer pressure of the nozzle 3.

The outside air of the nozzle portion 3 moves from the nozzle portion 3 toward the third conduit 34 to seat the second head member 86 of the second valve portion 80 in the mounting groove 46.

The second wing member 84 blocks the communication hole 47 while touching the stopper portion 48 in an unfolded shape, thereby preventing the outside air from moving to the inner groove 37 through the third pipe 34. .

The liquid in the container 9 is moved to the first conduit 32 along the hose member 8, and the liquid moved to the first conduit 32 is the first wing member 74 of the first valve part 70. ) To the upper side.

The first wing member 74 is moved upwards to be in contact with the lower end of the second conduit 33, the upper movement is constrained, the side of the first body member 72 guides the upward movement to the guide projection member 38 The operation reliability is improved by preventing the eccentricity and shaking of the first valve unit 70.

In a state in which the first valve part 70 is blocking the lower end of the second conduit 33, the liquid passing through the first conduit 32 is provided in the lower side of the second conduit 33. Move upward through.

The liquid passing through the passage hole 42 is moved to the inner groove portion 37, and the set amount of liquid is filled in the inner groove portion 37 so that the pressure difference between the inner groove portion 37 and the container 9 is less than or equal to the set value. When the first valve unit 70 blocks the first conduit 32, the movement of the liquid moved from the container 9 to the inner groove 37 stops.

On the other hand, the negative pressure protrusion 19, which is moved together with the piston 16, moves in the outward direction of the negative pressure groove 50 to block the inlet of the negative pressure groove 50, thereby preventing the movement of air through the negative pressure hole 54. .

According to the above-described configuration, the present invention provides a first valve unit 70 and a second valve unit 80 including the first wing member 74 and the second wing member 84 that are elastically unfolded. It is possible to control the flow of the fluid more precisely, so that the remaining amount of the liquid from the nozzle portion 3 can be prevented from falling.

In addition, since the air is replenished to the container 9 together with the injection operation, the deformation of the container 9 can be prevented, and a smoother injection operation can be made.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.

In addition, the home trigger spray apparatus has been described as an example, but this is merely exemplary, and the trigger spray apparatus of the present invention may be used in various types of fluid injection such as commercial use or industrial use.
