[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1-5 As shown, an aerosol valve with a locking function 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 limit mechanism are cooperated between the seat ring 1 and the valve cover 2; the flow channel mechanism includes a liner ring 3 fixed in the seat ring 1 and an arc plate 4 cooperatedly arranged on the liner ring 3, specifically, the liner ring 3 is fixed in the seat ring 2 by a plurality of connecting pieces 5, and the plurality of connecting pieces 5 are evenly distributed along the circumference of the liner ring 3, and a ring edge 6 is cooperated between the liner ring 3 and the valve cover 2; an L-shaped flow channel tube 7 is provided on the arc plate 4, and the flow channel tube 7 has a bottom inlet and a horizontal outlet, and the top surface of the flow channel tube 7 is rotatably connected to the valve cover 2, specifically, the top of the flow channel tube 7 The surface has a connecting seat 8, a T-shaped slot is provided in the connecting seat 8, a T-shaped column 9 is provided on the inner top surface of the valve cover 2 that cooperates with the T-shaped slot, a first bell mouth 10 corresponding to the horizontal outlet is provided on the arc plate 4, the first bell mouth 10 is a through hole, the valve cover 2 has a curtain piece 11, and in the natural state, the curtain piece 11 is pressed inward against the lining ring 3, and the top surface of the curtain piece 11 is fixedly connected to the valve cover 2, the curtain piece 11 has a mist outlet nozzle 12 that cooperates with the first bell mouth 10, and the arc plate 4 is also provided with a second bell mouth 13 that cooperates with the mist outlet nozzle 12, and the second bell mouth 13 is a blind hole; the above-mentioned seat ring 1, valve cover 2, lining ring 3, arc plate 4, connecting piece 5, flow channel tube 7 and curtain piece 11 are all made of plastic.

[0021] The above-mentioned downward pressure limiting mechanism includes a baffle 14 fixed to the inner side of the valve cover 2 and a baffle clearance notch 15 provided on the liner ring 3; when the mist outlet nozzle 12 is located in the first bell mouth 10, the baffle 14 is vertically aligned with the baffle clearance notch 15; when the mist outlet nozzle 12 is located in the second bell mouth 13, the lower edge of the baffle 14 is in contact with the top surface of the liner ring 3.

[0022] To reduce the force required to move the mist nozzle 12 in and out of the first bell-shaped opening 10 and the second bell-shaped opening 13, the curtain 11 is split in the middle. That is, the curtain 11 includes two left and right parts with a gap between the two parts. In this case, when the valve cover 2 is rotated, the two parts are pushed out of the first bell-shaped opening 10 or the second bell-shaped opening 13 in sequence, avoiding the problem of large resistance caused by directly pushing the entire curtain 11.

[0023] The working principle of this embodiment is:

[0024] When the spray is needed, the valve cover 2 is rotated so that the mist outlet 12 on the curtain 11 is inserted into the first bell mouth 10. At this time, the baffle 14 is vertically aligned with the baffle clearance notch 15. When the rear part of the valve cover 2 is pressed, the arc plate 4 itself will bend slightly, and the flow channel 7 presses down the downward pressure liquid outlet of the aerosol can. The liquid material in the aerosol can enters the flow channel 7 and is then sprayed out at the mist outlet 12.

[0025] After use, the valve cover 2 is rotated so that the mist outlet 12 on the curtain 11 is locked in the second bell mouth 13. At this time, the baffle 14 is no longer aligned with the baffle notch 15 and the lower edge of the baffle 14 is close to the top surface of the lining ring 3. When the rear part of the valve cover 2 is pressed, it will not be pressed down, so the aerosol can will not spray material, and the locking function is realized;

[0026] Compared with the prior art, the valve cover 2 in this embodiment is rotatable and the valve cover 2 can only be pressed down normally and the material spraying is completed when the mist outlet nozzle 12 on the valve cover 2 enters the first bell mouth 10 on the arc plate 4. This makes the aerosol valve have a locking function, avoids the safety hazards caused by accidental touch and mis-press operation, and is suitable for popularization and use.

[0027] The embodiments of the present invention are provided for purposes 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 skilled 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 skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
