[0021] The solution of the present application will be further described below in conjunction with the accompanying drawings:
[0022] See the attached Figures 1 to 7 , the aerosol can includes a can body 1 and a dual - head dual - bag dual valve 2.
[0023] The dual - head dual - bag dual valve 2 includes an end cap 21, a valve body assembly 22 and a bladder 23. The valve body assembly 22 includes a first valve core 221, a second valve core 222 and a valve core seat 223. The first valve core 221 and the second valve core 222 respectively include a valve body 201, a valve stem 202, a first sealing ring 203 and a return spring 204. At the lower end of the valve cavity 200 of the valve body 201, there is a first feed port 2011 communicating with the bladder. At the upper end of the valve cavity 200, there is a fitting port 2012 for the valve stem 202 to penetrate. The first sealing ring 203 is sleeved on the valve stem 202 and seals the fitting port 2012. At the sleeved position of the first sealing ring 203 on the valve stem 202, there is a second feed port 2021. When the valve stem 202 is pressed down, the second feed port 2021 is exposed in the valve cavity 200 to connect the valve cavity 200 with the discharge channel 2022 in the valve stem 2021. The valve core seat 223 is provided with installation positions 2231 for the first valve core 221 and the second valve core 221 to be respectively fitted. The first valve core 221 and the second valve core 222 are respectively inserted from the lower opening 2232 of the installation position 2231, and their valve stems 202 pass through from the upper opening 2233 of the installation position 2231.
[0024] The dual - head dual - bag structure of the present utility model can effectively separate and store two kinds of contents and extrude them independently, avoiding the pollution problem caused by mutual leakage and mixing between the contents. At the same time, due to the different flow states and densities of different contents, the dual - head valve core can ensure that the contents are in contact and mixed only after being extruded, avoiding the problem of accumulation and residue of the contents after mixing in the narrow valve of the traditional single - head valve core structure.
[0025] Furthermore, a suction nozzle 205 extending into the bladder 23 is provided at the lower end of the valve body 201. An inlet channel 2051 is provided in the suction nozzle 205. At the bottom end of the inlet channel 2051, there is a first suction port 2052, and on the side of the inlet channel 2051, there is a second suction port 2053. A suction tube 206 is sleeved on the suction nozzle 205, and on the outer surface of the suction nozzle 205, there are circumferentially protruding teeth 2054 for abutting against the inner wall of the suction tube 206, ensuring the tight connection between the suction nozzle 205 and the suction tube 206 and preventing loosening.
[0026] Further, three of the aforementioned second feed inlets 2021 are provided at the lower end of the discharge channel 2022, and a separator 2023 for separating each second feed inlet 2021 is provided inside the lower end of the discharge channel 2022. The separator 2023 keeps the second feed inlets 2021 unblocked during squeezing to avoid blockage caused by residue of the content.
[0027] Further, a sealing ring platform 224 extending outward is provided on the side of the valve element seat 223 for lapping with the mouth 11 of the tank body 1. A second sealing ring 225 is provided between the sealing ring platform 224 and the mouth 11 of the tank body. A plurality of circumferentially arranged elastic claws 226 for abutting against the inner wall of the tank body 1 are provided at the bottom of the valve element seat 223. During installation, the pre-assembled valve body assembly 22 and the bladder 23 are inserted into the tank body 1 from the mouth 11 of the tank body. When passing through the mouth 11 of the tank body, the elastic claws 226 are compressed and retracted towards the center direction and elastically reset after passing through the mouth 11 of the tank body to make them closely abut against the inner wall of the tank body at the end. At the same time, a force is provided to make the sealing ring platform 224 closely lap on the mouth 11 of the tank body. Finally, the end cover 21 is buckled and the cover edge of the end cover 21 is fixed to the mouth 11 of the tank body.
