Description

The present invention relates to the field of sprayers, especially to multi-stage variable spray guns.

See FIGS. 10-10. As shown in FIGS. 10 to 12, the well-known spray gun 80 has one lid 81. One pump 82 is arranged in the lid 81. A swing member 83 is pivotally mounted on the lid 81. When the swing member 83 is pulled by hand, one nozzle 84 is driven by the swing member 83 with respect to the lid 81, and a mist-like fluid is sprayed from the nozzle 84, and the pump 82 is opened to release a desired fluid. refill. As shown in FIGS. 10 to 12, the nozzle 84 has two ribs 85 protruding outside the nozzle 84 via one opening / closing portion 90 of the lid 81.

See FIGS. 1, 2 and 9. The multi-stage variable spray gun according to the embodiment of the present invention will be briefly described below with reference to FIGS. 1, 2 and 9. The spray gun 10 described above has one pump 20. One lid 30 is coupled to the pump 20. The connecting portion 41 for connecting the lid 30 and one swinging member 40 described above is used as one fulcrum, and the support lever 54 of one joining pipe 50 to which the swinging member 40 is pivotally attached is used as a pressing point. , The lid 30, the swinging member 40, and the joining pipe 50 are connected to each other. The joining pipe 50 is an L-shaped pipe. A nozzle 51 is attached to one end of the L-shaped tube. The nozzle 51 extends from one window 42 of the rocking member 40. The other end of the L-shaped tube is inserted through one opening / closing portion 70 and connected to the pump 20. One elastic member 60 is arranged between the pump 20 and the lid 30. The elastic member 60 pushes the pump 20 and the rocking member 40 can be constantly fastened to one starting position by the joining pipe 50 (see FIG. 1).

When the rocking member 40 is swung by the connecting portion 41 from the start position to the end position (see FIG. 9), the volume of the pump 20 can be changed by the joining pipe 50. Therefore, the swing width of the swing member 40 becomes equal to the stroke distance of the joining pipe 50, and the amount of compression of the volume of the pump 20 is determined.

The pump 20 described above (see FIG. 2) has one valve body 21. The valve body 21 is one stepped pipe. The stepped pipe has one large diameter portion 211 formed at one end and one small diameter portion 212 formed at the other end. One tapered hole 213 is formed inside the valve body 21 and is located between two large and small diameter portions 211 and 212.

The pump 20 has one check valve 22, one valve stem 23, one valve 24, and one vertical pipe 25. The check valve 22 described above is attached to the valve body 21 and always closes the tapered hole 213. The check valve 22 has one through hole 221. The valve rod 23 described above is inserted into the valve 24. Since one side of the valve 24 is one conical plate 231 of the valve rod 23 and the other side is connected to the vertical pipe 25 of the valve rod 23, the valve 24 is separated from each other even if the valve 24 is slid by the valve rod 23. Absent. The valve rod 23 and the valve 24 are inserted into the valve body 21 via the large diameter portion 211, and one ring piece 251 of the vertical pipe 25 protrudes from the valve body 21.

Further, one coupling ring 32 and one inner ring 33 are formed on the top surface of the lid 30. The coupling ring 32 and the inner ring 33 have a concentric structure, surround both the inside and the outside of the large diameter portion 211, engage the lid 30 with the valve body 21, and prevent the pump 20 from separating from the lid 30.

The elastic member 60 is a compression spring. One end of the compression spring is pressed against the ring piece 251 and the other end is in contact with the bottom of the spring tank 34 of the inner ring 33. Since the vertical pipe 25 is connected to the joint pipe 50, the elastic member 60 drives the joint pipe 50 and keeps the swing member 40 at the start position.

When in the starting position, the conical plate 231 pushes the valve 24 into contact with the inner ring 33, which constantly closes one vent 214 of the valve body 21. At this time, the volume of the valve body 21 is maximized from the check valve 22 to the valve 24.

When in the starting position, the vertical pipe 25 brings the valve stem 23 closer to the check valve 22 and pushes the valve 24 away from the vent hole 214. At this time, the volume of the valve body 21 is minimized from the check valve 22 to the valve 24, and the ring piece 251 approaches the inner ring 33 to compress the elastic member 60.

In other words, the volume of the pump 20 is compressed when it is in the starting position and expanded when it is in the starting position.

The pump 20 is inserted into the internal space 16 of one container 12. When one threaded portion 31 of the lid 30 is screwed into one inlet / outlet 14 of the container 12, the pump 20 is supported so as to remain in the internal space 16 of the container 12. One end of the flexible pipe 18 is connected to the small diameter portion 212, and the other end is deeply inserted into the internal space 16 to guide the contents of the container 12 into the pump 20. Here, the content refers to a fluid that can be injected in the form of a liquid or mist.

When in the all-out position, the valve 24 separates from the conical plate 231 and one material discharge channel 232 of the valve stem 23 is not closed. The contents of the valve body 21 flow into the joining pipe 50 from the material discharge channel 232, and quickly pass through the nozzle 51 to form a constant spray range 52.

When the swing member 40 is loosened, the elastic member 60 is restored to its original state, the joint pipe 50 is pushed to return to the original position, and the swing member 40 returns from the start position to the start position. At the same time, when the pump 20 changes from the compressed volume to the expanded volume to generate a suction force and pulls the check valve 22 away from the tapered hole 213 of the valve body 21, the pressure inside and outside the container 12 passes through the ventilation hole 214. The contents of the container 12 pass through the tapered hole 213 and the through hole 221 around the flexible pipe 18, and the check valve 22 is separated from the valve body 21 corresponding to the valve 24 and refilled in the expanded container. Will be done.

Here, since the spray amount of the nozzle 51 is equal to the compressed volume of the pump 20 and the compression container and the expansion container are the same, the amount of the pump 20 pumping the internal volume of the container 12 is the spray amount of the nozzle 51. equal. The amount of spray and the amount of pumping can be determined by changing the stroke of the joining pipe 50.

Hereinafter, a method of changing the spray amount and the pumping amount of the spray gun by the opening / closing unit 70 will be described with reference to FIGS. 3 to 8.

The opening / closing portion 70 described above is a circular tube. The circular tube is attached to the coupling ring 32 and can be swiveled around the junction tube 50. A set of convex points 71 and two stopper portions 73 are projected on the outer surface of the opening / closing portion 70. These stopper portions 73 are located on both sides of a set of convex points 71, and one of the convex points 71 is engaged with one positioning portion 35 of the lid 30. The positioning unit 35 limits one index 72 of the opening / closing unit 70 toward the swing member 40 of the spray gun 10 (see FIG. 1).

The opening / closing portion 70 uses one end facing the joining pipe 50 as the top end 75 (see FIG. 1), and forms a bottom end 76 at one end where the opening / closing portion 70 is deeply inserted into the coupling ring 32. Two steps 77 are formed at symmetrical positions of the inner portion 74 (see FIG. 5), and the two gaps 785 are formed by these steps 77.

In the direction from the top end 75 to the bottom end 76, each step 77 has a first step 771, a second step 772, a third step 773, a fourth step 774, and a fifth step 775. In this order. The first step portion 771 has a step, but this step is small and is not considered here. The altitude head 781 from the second step 772 to the top end 75 of the opening / closing part 70 is smaller than the altitude head 782 from the top end 75 to the third step 773. By the same reason, the altitude head 784 of the fifth step 775 is larger than the altitude head 783 of the fourth step 774.

The index 72 is located in front of the positioning unit 35 (see FIG. 6). The fourth step 774 of the two steps 77 corresponds to two ribs 53 provided at symmetrical positions on the outside of the joint pipe 50. The rib 53 described above is stopped by the fourth step portion 774, makes the stroke distance of the linear displacement of the joining pipe 50 equal to the altitude head 783, and controls the spray amount (or the pumping amount) of the spray gun.

The above-mentioned opening / closing portion 70 is rotated around the joining pipe 50 until the stopper portion 73 (see FIG. 7) is brought into contact with the positioning portion 35 in the direction of arrow 791. When the positioning portion 35 is engaged with the convex point 71, the index 72 stays on one side of the positioning portion 35, and at this time, the first step portion 771 of the two steps 77 reaches below the rib 53, and the joining pipe In order to stop the displacement of 50, the spray gun is turned off and spraying becomes impossible.

The above-mentioned opening / closing portion 70 is rotated around the joining pipe 50 until the stopper portion 73 (see FIG. 8) is brought into contact with the positioning portion 35 in the direction of arrow 792. When the positioning portion 35 is engaged with the convex point 71, the index 72 stays on the other side of the positioning portion 35, and at this time, the rib 53 slides smoothly in the gap 785 of the two steps 77, and the joining pipe 50 Since the stroke of the linear displacement of is not limited, the maximum spray amount (or pumping amount) can be obtained by operating the spray gun.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like within a range not deviating from the gist of the present invention are also included.
