In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As Figures 1-5 shown, a multi-purpose aerosol button valve described in this embodiment includes a valve seat 1, a valve plate 2, and a retaining pin 3; the left side of the valve plate 2 is hinged to the valve seat 1 through a hinge shaft 4, a main flow channel 5 is provided in the valve plate 2, a variable nozzle 6 is hinged to the left side of the main flow channel 5. Specifically, horizontal shafts are respectively provided on the front and rear sides of the variable nozzle 6, and shaft holes for cooperating with the horizontal shafts are provided on the left side of the valve plate 2. A first flow channel 7 and a second flow channel 8 that can communicate with the main flow channel 5 are provided in the variable nozzle 6. The first flow channel 7 and the second flow channel 8 are independent of each other. The first flow channel 7 is horizontally arranged, and the second flow channel 8 is vertically arranged and located behind the first flow channel 7. An extension tube is detachably inserted at the outlet of the first flow channel 7; a ball head 9 is provided on the right side of the variable nozzle 6, an opening for cooperating with the ball head 9 is provided on the left side of the main flow channel 5, and a rubber gasket 10 is provided at the opening.

[0021] One side of the bottom surface of the bayonet pin 3 is hinged on the valve seat 1. Specifically, a vertical shaft 11 is fixedly provided on the valve seat 1. The rear side of the bottom surface of the bayonet pin 3 is provided with an axial hole matching the vertical shaft 11. A locking nut is fixedly provided on the upper end of the vertical shaft 11 to prevent the bayonet pin 3 from slipping out upward. The bayonet pin 3 is provided with a card slot 12, and the right side of the valve plate 2 is provided with a card block 13 matching the card slot 12; a valve plate return mechanism is provided between the hinge shaft 4 and the valve seat 1, so that the valve plate 2 can automatically return to the center when not pressed by the user so that the card block 13 is aligned with the card slot 12 on the bayonet pin 3, which greatly facilitates the pin-in fit of the bayonet pin 12. The above-mentioned valve plate return mechanism includes a strip block 14 fixedly provided on the end surface of the hinge shaft 4, and the strip block 14 has round corners Arc chamfer, elastic sheets 15 are symmetrically arranged on the upper and lower sides of the strip block 14, the elastic sheets 15 fit the strip block 14, and both ends of the elastic 15 are fixedly connected to the valve seat 1. When the hinge shaft 4 rotates, the strip block 14 is driven to rotate, and the strip block 14 rotates to open the two elastic sheets 15. When the finger no longer presses the valve sheet 2, the two elastic sheets 15 return to straightness, and at the same time drive the strip block 14 and the hinge shaft 4 to rotate in the opposite direction, and finally the elastic sheet 15 returns to the straight state without deformation. When the elastic sheet 15 is not deformed, the block 13 and the slot 12 are in the same horizontal plane, and the block 13 can directly enter the slot 12 on the bayonet 3; the elastic sheet 15 is a spring steel sheet with a thickness of 0.3mm-0.8mm.

[0022] A through hole 16 is provided on the top surface of the bayonet 3, and an elastic locking piece 17 is provided in the through hole 16. The middle part of the elastic locking piece 17 is fixedly connected to the bayonet 3, and a hemispherical locking bead 18 is provided on the left side of the bottom surface of the elastic locking piece 17. The block 13 has an arc-shaped groove matched with the hemispherical locking bead 18. After the bayonet 3 and the block 13 are in place, the hemispherical locking bead 18 is inserted into the arc-shaped groove to prevent the bayonet 3 from being easily unlocked from the block 13. When unlocking is required, the right side of the elastic locking piece 17 is pressed by a finger to assist the hemispherical locking bead 18 to escape from the arc-shaped groove. At this time, the bayonet 3 can be easily unlocked from the block 13. The materials of the bayonet and the elastic locking piece are both plastic.

[0023] The working principle of this embodiment is:

[0024] When the aerosol is sprayed, the latch 3 is toggled to unlock the latch block 13 from the latch 3. At this time, the right side of the valve plate 2 can move up and down. The variable nozzle 6 is rotated to adjust the communication between the first flow channel 7 or the second flow channel 8 and the main flow channel 5. The right side of the valve plate 2 is pressed, and the pressing discharge port of the aerosol bottle is pressed to eject the material. The material enters from the right side of the main flow channel 5 and is ejected through the first flow channel 7 or the second flow channel 8. After the spraying is completed, the valve plate 2 is released. Under the action of the valve plate centering mechanism, the valve plate 2 returns to the horizontal position. The latch block 13 aligns with the card slot 12 on the latch 3, and the latch 3 is swung back to its position. The latch block 13 is reinserted into the latch 3. At this time, the valve plate 2 will no longer move up and down, and the material cannot be ejected. Compared with the prior art, in this embodiment, the attitude of the variable nozzle 6 can be adjusted to switch the spraying of the first flow channel 7 or the second flow channel 8. The first flow channel 7 is externally connected to an extension tube, which can meet the precise spraying of narrow gaps or local small points. The second flow channel 8 can meet the rough spraying of a larger area in the vicinity, well adapting to different usage requirements of users. In addition, in this embodiment, the anti-misoperation function of the valve plate 2 is realized through the cooperation of the latch 3 and the latch block 13. The insertion and removal of the latch 3 are very convenient and can be operated with one hand, with strong practicability. The hinged design also makes the latch 3 not easy to be lost.

[0025] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
