The present invention relates to a small trigger spraying apparatus, and more particularly, to a trickle atomizing apparatus which can be used even in the case of a mill which is capable of spraying a solution by pulling a trigger even when it is in an upright state.

Generally, a small atomizer pumped and sprayed the contents (solution) stored in a container, and a spray device is attached to the upper part of the container. That is, the conventional small-sized sprayer has a container in which liquid or paste-like cosmetics or other contents are stored, a cap detachably coupled to a neck of the container, and a cap attached to the top of the cap, And a trigger-type spraying device for spraying a predetermined amount of water.

Further, a suction tube is coupled to the suction port of the pump mechanism, and the lower end of the suction tube extends to the bottom of the container.

Thus, as the user repeatedly pulls the trigger, the solution in the container is sucked into the pump mechanism through the suction tube and subsequently extruded through the spray nozzle into the spray form. At this time, spraying is possible in a state in which the spraying apparatus is standing upright (standing state), but it is impossible to use the spraying apparatus in a state where the spraying apparatus is upside down (standing state).

That is, when the conventional spraying apparatus is inverted, the tip of the suction tube is exposed to the air inside the container, so that the solution suction is not performed. Therefore, the conventional trigger type spraying apparatus can be used only in a standing state, and there are disadvantages that there are many restrictions on the use conditions.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. (In the embodiment of the present invention, a spraying apparatus is applied to a small-sized spraying apparatus as an example.)

1, a small atomizer to which the present invention is applied includes a container 10 in which a solution (contents) is stored, a cap 20 detachably coupled to an upper portion of the container 10, And a trigger type spraying device 30 for spraying the solution contents into a spray type.

The container 10 is a synthetic resin container in which the solution is directly stored, and a neck 11 having a predetermined inner diameter is integrally formed on the container 10. A male thread is formed on the outer periphery of the neck 11 of the container 10 for engagement with the cap 20.

The cap 20 is for detachably coupling the spray device 30 to the neck 11 of the container 10 and is formed into a cylindrical shape through a synthetic resin and a female screw is integrally formed on the inner wall.

The trigger type spraying device 30 sucks and pumped the solution in the container 10 and is provided with a valve housing 40 mounted to the neck 11 of the container 10, A spray nozzle 70 which is rotatably installed on the tip of the sprayer body 60 and a spray nozzle 70 which is rotatably mounted on the tip of the spray gun main body 60, A trigger 80 for actuating the pumping means 50 in operation and a switching valve assembly 100 which is capable of guiding the solution suction even when the container is in the upright position.

The valve housing 40 is mounted directly to the neck 11 of the container 10 through the cap 20 and is provided with a valve seat 43, A flow path 41 is formed. The guide bush 42 is formed in a cylindrical shape at the bottom of the valve housing 40 so as to be fitted into the sprayer main body 60. The guide bush 42 is provided with a suction passage 41 eccentrically (See FIGS. 3 and 4). The primary check valve 44 disposed on the upstream side of the suction passage 41 is closed during the pulling operation of the trigger 80 to prevent the solution in the sprayer body 60 from flowing backward, Thereby allowing solution inhaling through assembly 100. A valve seat 62 is constituted so that a secondary check valve 63 is seated on the downstream side of the suction passage 41. The secondary check valve 63 is opened during a spray operation and the solution suction And is operated to close by the elastic restoring force of the coil spring.

The sprayer main body 60 includes a pumping means 50 for sucking the solution through the suction path 41 and delivering the solution to a predetermined pressure, And a discharge channel 61 for guiding the solution discharged from the spray nozzle 70 to the spray nozzle 70 side. The pumping means 50 includes a cylinder 51 extending in the horizontal direction in association with the suction flow path 41 and a plunger 54 elastically supported via a coil spring 53, (Not shown). When the plunger 52 moves backward while compressing the coil spring 53, the solution in the cylinder 51 is pressurized and is discharged to the discharge flow path 61. By the resilient restoring force of the coil spring 53, The solution is sucked into the cylinder 51 and temporarily stored.

The discharge passage 61 extends horizontally on the upper side of the cylinder 51 and is connected to the suction passage 41 and the cylinder 51. A spray nozzle 70 is rotatably fitted in the tip end portion of the discharge flow path 61. That is, the spray nozzle 70 is mounted at the tip of the sprayer body 60 and discharges the solution in spray form. Reference numeral 54 denotes a negative pressure hole formed in the wall of the cylinder 51 so that external air enters into the vessel 10 when the solution is sucked into the cylinder 51. [

The tip of the plunger 52 is coupled to the rear surface of the trigger 80 so that the plunger 52 can be repetitively pulled by the resilient restoring force of the coil spring 53. The sprayer main body 60 And is rotatably hinged to the distal end of the hinge unit.

The switch valve assembly 100 allows the solution to be sucked even when the container is inverted or upside down. The switch valve assembly 100 includes an upper casing 110 fitted to the suction passage 41 of the valve housing 40, A lower casing 120 fitted to the bottom of the upper casing 110 to form a space S for temporarily storing the solution therein and a suction tube 130 coupled to a lower portion of the lower casing 120, And a switching valve 140 provided on the upper side of the upper casing 110 to selectively allow suction of the solution.

The components constituting the switching valve assembly 100 will be described in detail with reference to FIGS. 2 to 4. FIG.

A first coupling hole 112 is formed in the upper surface 11 of the upper casing 110 so as to be inserted into the lower end of the suction passage 41 of the valve housing 40, Respectively. An assembly jaw 114 protrudes from the wall surface 113 of the upper casing 110 and the first coupling hole 112 is formed eccentrically on the upper surface 111 of the upper casing 110. The assembly jaw 114 serves to guide the assembling direction of the lower casing 120 to coaxially maintain the eccentric first engaging portion 112 and the second engaging portion 122. In the inner periphery of the wall surface 113 of the upper casing 110, a coupling groove 115 in the form of a strip is formed in the circumferential direction to assemble the lower casing 120 more securely.

The lower casing 120 is cylindrically opened with its upper portion opened, and is inserted and coupled through an open lower portion of the upper casing 110. Therefore, when the upper casing 120 and the lower casing 120 are assembled, a space S in which the solution is temporarily stored is formed therein. A second coupling hole 122 for guiding the solution sucking is eccentrically provided on the lower surface 121 of the lower casing 120, and the upper end of the suction tube 130 is fitted to the lower coupling surface. The lower end of the suction tube 130 extends to the bottom of the container 10 so that when the container 10 is in the upright state, the suction tube 130, the space formed by the upper casing 110 and the lower casing 120, (S).

An assembly guide portion 124 is formed on the wall surface 123 of the lower casing 120 so as to project the assembly guide 114 of the upper casing 110 to be received therein. The assembly guide portion 124 allows the lower casing 120 to be engaged with the upper casing 110 only in the assembling direction in which the lower casing 120 is set so that the first coupling hole 112 and the second coupling hole 112, 122 are coaxial. A coupling protrusion 125 is formed on the outer circumference of the wall surface 123 of the lower casing 120 so as to be engaged with the coupling groove 115. Therefore, when the lower casing 120 is inserted through the opened lower portion of the upper casing 110, the coupling tabs 125 are coupled to the coupling tabs 115 in a concave-convex coupling manner and are not separated unless an artificial force is exerted. The assembling jaw 114 is received and engaged with the guide portion 124. Accordingly, the first and second coupling parts 112 and 122 are coaxial with each other, so that the solution is immediately sucked in a straight line in a state in which the container 10 is in a set state.

The switching valve 140 is opened when the container 10 is in an upright position and permits suction of the solution into the space S between the upper and lower casings 110 and 120. When the container 10 is set A valve seat portion 142 for opening the upper and lower portions of the upper surface 111 of the upper casing 110 to secure the solution passage 141 and a valve seat portion 142 disposed inside the valve seat portion 142, A plurality of balls 143 provided at regular intervals along the open top edge of the valve seat portion 142 so as to prevent the balls 143 from separating from each other; And is defined as a latching jaw 144. The valve seat 142 is formed in a hopper shape in which the inner diameter gradually decreases from the upper surface 111 of the upper casing 110 toward the lower side. Therefore, when the container 10 is inverted, the ball 143 is lowered due to its own weight, thereby closing the solution passage 141 of the valve seat portion 142. On the other hand, in a state where the container 10 is upside down, that is, in an inverted state, the ball 143 is lowered by its own weight and held in the engagement step 144, (141) is opened.

Since the switch valve assembly 100 has the eccentric first engagement portion 112 and the second engagement portion 122, it must be accurately assembled to the suction passage 41 of the valve housing 40. A pair of assembly ribs 112 are provided on the upper surface 111 of the upper casing 110 so as to be opposed to both sides of the first coupling hole 112 so as to be accommodated between the suction passage 41 and the inner wall of the guide bush 42. [ (116L) and (116R) protruding from each other. Since the pair of assembly ribs 116L and 116R can be assembled only in the space between the inner wall of the guide bush 42 and the outer side of the eccentric suction passage 41, the switching valve assembly 100 can be assembled only in the predetermined direction (See Figs. 3 and 4). This prevents the switch valve assembly 100 from being idled while assembled to the valve housing 40 and to prevent interference with the process of coupling the cap 20 to the neck 11 of the receptacle 910 to be.

Next, operation of the trigger-type spraying apparatus which can be used even in the inhalation according to the present invention constructed as above, and the operation and effect thereof will be described with reference to FIG. 1 and FIG.

1, when the user pulls the trigger 80 backward while the sprayer 30 and the vessel 10 are set up, the coil spring 53 is compressed and the plunger 52 And enters the cylinder 51. Therefore, the solution filled in the cylinder 51 is injected to the outside through the discharge passage 61 and the spray nozzle 70 while opening the secondary check valve 63. At this time, since the primary check valve 43 is kept closed with the suction passage 41, the solution in the cylinder 51 is only pushed toward the spray nozzle 70 side.

When the user releases the trigger 80, the plunger 52 is again projected by the restoring force of the coil spring 53, and at the same time, the trigger 80 is restored to the initial state, and vacuum pressure is applied to the cylinder 51. The primary check valve 44 is moved upward to open the suction passage 41 by the air pressure difference between the cylinder 51 and the vessel 10 so that the solution in the vessel 10 is sucked through the suction tube 130 Is sucked into the cylinder 51 through the inner space S of the upper and lower casings 110 and 120 of the switching valve assembly 100 → the opened suction passage 41 (see the arrow direction of FIG. 1). At this time, since the secondary check valve 63 is pressurized in the direction of closing the discharge passage 61, leakage phenomenon does not occur. In addition, since the switching valve 140 of the switching valve assembly 100 is also closed by its own weight and negative pressure, only the suction of the liquid is made through the suction tube 130. In the container 10 from which a part of the solution has escaped, external air of a volume corresponding to the volume thereof is filled through the negative pressure hole 54, and the spraying device 30 is maintained in the initial state.

5, the user can pull the trigger 80 upwards, that is, in the inverted state, that is, in the inverted state. In this case, the upper end of the suction tube 130 is positioned inside the container 10 The valve 140 of the switch valve assembly 100 is opened and the solution passage 141 is secured. That is, the ball 143 of the switching valve 140 is lowered by its own weight, and the solution passage 141 is opened.

Thus, when the trigger 80 is repeatedly operated, the solution in the container 10 is returned to the open switching valve 140 of the switching valve assembly 100 and the upper and lower casing 110 (120) of the switching valve assembly 100 (See arrow direction in FIG. 5) by sucking the solution into the cylinder 51 through the inner space S of the inner space S and the suction path 41. On the other hand, when the trigger 80 is operated and the negative pressure hole 54 is opened and the solution in the container 10 is to be discharged to the negative pressure hole 54 side, the outside air is introduced into the container 10 by the air pressure difference , Even if the atomizing device 30 is used in an inverted state, the solution does not flow out into the operating section of the piston 52. [

As described in detail above, According to the trigger spraying apparatus according to the present invention, since the switch valve assembly allowing the suction of the container is disposed even when the container is supported at the end of the suction flow path of the valve housing, the trigger can be repeatedly The solution can be sprayed on the surface, which makes it possible to double the usability.

A lower casing coupled to an open bottom portion of the upper casing to form a solution storage space; an upper casing provided on an upper surface of the upper casing to open And a change-over valve for allowing the solution to be sucked, and has an advantage that it can be easily applied without modifying the conventional configuration of the trigger-type atomizing device.
