[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0014] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0015] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0016] Reference Figures 1 to 3 A double-pad adjustable aerosol valve comprises a sealing cup 1, a valve body 2 is installed in the sealing cup 1, the sealing cup 1 is provided with a valve chamber, the valve body 2 is installed in the valve chamber, the valve chamber is located at the upper end of the valve body 2 and is provided with an adjusting groove 4 communicated with the valve body 2, an upper gasket 5 and a lower gasket 6 are respectively installed at the upper and lower ends of the adjusting groove 4, the upper gasket 5 is in contact with the inner top of the valve chamber, and the lower gasket 6 is in contact with the top surface of the valve body 2, and two different mist outputs are achieved by pressing to the adjusting groove 4 or pressing to the limit. Different mist outputs are selected according to different usage scenarios, and the double gasket structure has better air tightness.

[0017] The upper and lower ends of the adjusting groove 4 are both provided with mounting bayonet holes, and the upper gasket 5 and the lower gasket 6 are installed in the corresponding mounting bayonet holes.

[0018] The valve body 2 includes a valve body seat 7, in which a valve stem 8 is movably mounted and reset by a reset spring 3. An air inlet end connected to the aerosol tank is provided in the valve body seat 7. When the valve stem 8 is pressed, the air inlet end is connected to the regulating groove 4.

[0019] The valve stem 8 is provided with an air outlet end, and a side wall of the air outlet end is provided with an air outlet hole 9.

[0020] The valve body of the utility model has the same structure as that of a conventional aerosol valve, and the mist discharging principle is also the same.

[0021] When the amount adjustment groove is pressed, the medicine in the aerosol can enters the valve body 2 through the air inlet end, so that the medicine enters the amount adjustment groove 4, and finally enters the air outlet end through the air outlet hole 9 and is discharged from the aerosol can.

[0022] When the pressure is pressed to the limit, the medicine in the aerosol can enters the valve body 2 through the air inlet end, directly enters the air outlet end through the air outlet hole 9, and is discharged from the aerosol can, which is the same as the mist discharge principle of a conventional aerosol valve.

[0023] That is, the present application only adds a metering groove at the upper end of the valve body 2, and gasket seals are installed at the upper and lower ends of the metering groove. When the metering groove 4 is pressed, the medicine in the aerosol can enters the valve body 2 and then enters the air outlet end through the metering groove 4, thereby achieving a small amount of mist output (relative to the amount of mist output when pressed to the limit).

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
