2. The aerosol valve of claim 1, wherein the valve housing structure has a mounting cavity for mounting the valve stem member, and the valve stem is movably mounted in the mounting cavity.

3. The unitary binary hybrid architecture aerosol valve of claim 2, wherein the mounting cavity is provided with first mounting portions having alternating concavities and convexities, one end of the valve rod member mated with the mounting cavity is provided with second mounting portions having alternating concavities and convexities, and the first mounting portions are mated with the second mounting portions, so that the valve rod member can be more stably mounted in the mounting cavity.

4. The aerosol valve of claim 2, wherein an elastic member is further disposed in the mounting cavity, and the elastic member has a constant tendency to return the valve stem member.

5. The aerosol valve of claim 2, wherein the support member is mounted in the mounting cavity, a through hole is formed through the support member, and the valve rod member passes through the through hole and cooperates with the mounting cavity.

6. The aerosol valve of claim 5, wherein the mounting cavity is further provided with a third mounting portion with alternate concavities and convexities, the support member is provided with a fourth mounting portion with alternate concavities and convexities, and the third mounting portion cooperates with the fourth mounting portion to strengthen the mounting of the support member in the mounting cavity.

7. The aerosol valve of claim 1, wherein one end of the valve housing structure is further connected with a welding member, and a third sealing member is further disposed between the welding member and the valve housing structure, and the welding member and the valve housing structure are in sealing fit through the third sealing member.

8. The aerosol valve of claim 7, wherein the welding member is provided with a cavity cooperating with the passage, the cavity being connected with a conduit for discharging.

9. The aerosol valve of claim 8, wherein the weld is further connected to a pouch, the pouch is sealingly connected to the weld, the pouch encloses a cavity, and the conduit is disposed within the pouch.

10. A spray can comprising a can body, and further comprising a unitary binary hybrid construction aerosol valve according to any one of claims 1 to 9, the securing assembly comprising a securing member and a fourth sealing member, the can body being mounted on the securing member, the fourth sealing member being disposed between the securing member and the can body whereby the securing member is in sealing engagement with the can body.
