[0021] As Figures 1-5 shown, a misoperation prevention aerosol valve described in this embodiment includes a seat ring 1 and a valve cover 2 rotatably arranged on the seat ring 1; a flow channel mechanism and a downward pressure limiting mechanism are cooperatively arranged between the seat ring 1 and the valve cover 2; the flow channel mechanism includes a lining ring 4 fixedly arranged in the seat ring 1 through a plurality of connecting pieces 3 and an L-shaped flow channel 5 fixedly arranged on the lining ring 4. Specifically, a wing 6 is integrally arranged on the lining ring 4, the flow channel 5 is fixedly arranged on the wing 6, the flow channel 5 has a bottom inlet 7 and a horizontal outlet 8, the bottom inlet 7 is buckled on the downward pressure type liquid outlet of the aerosol can, and when it is pressed down, liquid material can be sprayed into the flow channel 5 through the bottom inlet 7 of the flow channel 5. A rotating mechanism is cooperatively arranged between the top surface of the flow channel and the valve cover 2. The rotating mechanism includes a T-shaped rotating shaft 9 fixedly arranged on the inner top surface of the valve cover 2 and a T-shaped groove cooperatively arranged on the top surface of the flow channel 5. The valve cover 2 has an opening 10 corresponding to the horizontal outlet 8;

[0022] The downward pressure limiting mechanism includes a dial 11 and a baffle 12 fixedly arranged on the inner side of the valve cover 2 and a rib 13 and a stop block 14 fixedly arranged on the lining ring 4. The number of the ribs 13 is three, and a first gap 15 and a second gap 16 are sequentially formed between the three ribs 13. When the valve cover 2 rotates, the dial can be driven to enter the first gap 15 or the second gap 16; the lower edge of the baffle 12 fits the lining ring 4, the upper edge of the stop block 14 is higher than the lower edge of the baffle 12, a baffle allowing gap 17 is arranged on one side of the stop block 14. When the dial 11 is located in the first gap 15, the opening 10 is aligned with the horizontal outlet 8 of the flow channel 5 and the baffle 12 can sink into the baffle allowing gap 17. When the dial 11 is located in the second gap 16, the opening 10 is not aligned with the horizontal outlet 8 of the flow channel 5 and the lower edge of the baffle 12 is blocked by the lining ring 4 and cannot sink.

[0023] The seat ring 1, valve cover 2, wing 6, lining ring 4, paddle 11, baffle 12, rib 13 and block 14 are all made of plastic. In order to further increase the number of reciprocating bending times of the paddle 11 and ensure its service life, elastic metal patches 18 are fixedly arranged on both sides of the paddle 11. A protrusion 19 is integrally arranged on the elastic metal patch 18. The protrusion 19 is close to the lower side of the elastic metal patch 18. Hollow metal hemispheres 20 corresponding to the protrusions 19 are respectively arranged on the first and last ribs 13. A plurality of slits 21 are evenly distributed on the hollow metal hemisphere 20. The elastic metal patch 18 and the hollow metal hemisphere 20 are both made of spring steel. After the paddle 11 completely passes over the middle rib 13, the protrusion 19 will hit the hollow metal hemisphere 20 and make a sound, prompting the user of the change in the position of the paddle 11. The slit 21 can enhance the sound effect.

[0024] A first ring edge 22 is also provided on the outer ring of the liner ring 4, and a second ring edge 23 matching the first ring edge 22 is also provided on the valve cover 2, so as to further enhance the assembly stability of the valve cover 2 and the seat ring 1 when the valve cover 2 can rotate relative to the seat ring 1.

[0025] The working principle of this embodiment is:

[0026] When spraying is required, the valve cover 2 is rotated to align the opening 10 with the horizontal outlet 8 of the flow channel 5. At this time, the paddle 11 is located in the first gap 15, and the baffle 12 is aligned with the baffle gap 17 and can sink into it. The valve cover 2 is pressed, and the liquid material is sprayed out from the horizontal outlet 8 and the opening 10. When the valve cover 2 is released, the valve cover 2 returns to the horizontal state under the elastic action of the wing 6;

[0027] After the spraying is completed, the valve cover 2 is rotated until the baffle 12 is blocked by the block 14, and the valve cover 2 cannot continue to rotate. At this time, when the paddle 11 is located in the second gap 16, the opening 10 on the valve cover 2 is not aligned with the horizontal outlet 8 of the flow channel 5, and the lower edge of the baffle 12 is not aligned with the baffle clearance gap 17. At this time, the valve cover 2 is pressed down, and the lower edge of the baffle 12 will be supported by the lining ring 4, the valve cover 2 cannot be pressed down, and the liquid material will not be sprayed out; compared with the prior art, in this embodiment, the valve cover 2 can only be pressed down normally when the opening 10 on the valve cover 2 is aligned with the horizontal outlet 8 of the flow channel 5. This avoids the safety hazards caused by accidental touch and pressure operations, and has strong practicality.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, 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 uses.
