Description

Technical Field

[0001] This utility model relates to the field of aerosol valve technology, and in particular to a dual-purpose sustainable spray valve. Background Technology

[0002] The aerosol valve is the spraying mechanism on the aerosol can. When in use, pressing the button moves the valve stem downwards, disengaging the metering orifice from the valve stem seal and connecting the stem to the outer chamber. Under the pressure of the propellant inside the can, the contents flow through the suction tube, chamber, and metering orifice into the valve stem, finally being sprayed out from the button nozzle at the top of the valve stem. When the spring pushes the valve stem back, the nozzle is sealed, and the valve is closed again. Currently, most aerosol valves on the market use a forward spray method, meaning the button on top of the aerosol valve must be vertically upwards for normal spraying. To improve the aerosol's performance... Regarding performance, a universal aerosol valve has been invented, which has a diversion shell at the lower end of the outer casing. By using this aerosol valve, the aerosol can be sprayed at any angle, which greatly facilitates the use of aerosols. At present, the lower end of the aerosol valve is connected to a straw, which is generally directly inserted into the connector at the lower end of the diversion shell. Since there is no other fixing structure at the connection between the straw and the connector, the straw may loosen and fall off during transportation or if the aerosol is accidentally dropped, which affects the normal use of the aerosol.
