The aerosol can 10 further includes a receiving valve 104, and the receiving valve 104 is embedded in the bottom cover 101c of the storage tank 101. The aerosol container 10 further includes a first connecting structure 105, and the first connecting structure 105 is fixedly disposed on the bottom of the container body 101a or the bottom cover 101 c. In order to realize the split, detachable structure of the storage tank 101, the connection between the tank 101a and the top cover 101b, the connection between the tank 101a and the bottom cover 101c, the connection between the main valve 102 and the top cover 101b, and/or the connection between the receiving valve 104 and the bottom cover 101c are detachable connections, i.e., at least one of the first four connections is a detachable connection. This detachable connection may ensure that the storage tank 101 can be opened, which in turn permits the user to add the base product repeatedly to the storage tank 101.
In the present embodiment, in order to achieve a fixed connection between first connection structure 105 and storage tank 101, first connection structure 105 and a portion of storage tank 101 are integrally formed. For example, the first connecting structure 105 is integrally formed with the tank body 101a of the storage tank 101. For another example, the first coupling structure 105 is integrally formed with the bottom cover 101c of the storage tank 101. Furthermore, in other embodiments, the connection between first connection structure 105 and tank 101 may also be selected from welding, adhesive, snap-fit, threaded, etc.
The surge tank 20 includes a tank 201 for storing propellant, a built-in release valve 202 provided in the top of the tank 201, and a second connecting structure 203 fixedly provided on the top of the tank 201.

The clamping or screw connection is a conventional detachable connection, and has the advantages of mature technology and low cost.
In this embodiment, the aerosol canister 10 includes a first seal, a second seal, a third seal, and/or a fourth seal. Wherein a first seal is provided in the joint interface between the can body 101a and the top cover 101b, a second seal is provided in the joint interface between the can body 101a and the bottom cover 101c, a third seal is provided in the joint interface between the main valve 102 and the top cover 101b, and a fourth seal is provided in the joint interface between the receiving valve 104 and the bottom cover 101 c.
In the present embodiment, one of the first connecting structure 105 and the second connecting structure 203 includes a male snap structure, and the other includes a female snap structure, so that the first connecting structure 105 and the second connecting structure 203 can be snapped together, thereby completing the mechanical connection between the aerosol canister 10 and the pressure compensating canister 20. In other embodiments, one of the first and second connection structures 105 and 203 includes an internal thread structure and the other includes an external thread structure, whereby the first and second connection structures 105 and 203 may be threaded to complete the mechanical connection between the aerosol canister 10 and the pressure buildup canister 20.
In this embodiment, one of the receiving valve 104 and the release valve 202 is a male or female valve, and the other is a male valve. When one of the receiving valve 104 and the release valve 202 is a female valve and the other is a male valve, if the first connection structure 105 of the aerosol canister 10 is connected to the second connection structure 203 of the pressure supplementing canister 20, the male valve can be inserted into the female valve in such a way that the male and female valves can be opened and brought into communication with each other, so that the pressure supplementing canister 20 can add the stored propellant to the aerosol canister 10 for the purpose of pressure supplementing and aerating the aerosol canister 10. When the receiving valve 104 and the releasing valve 202 are both male valves, if the first connecting structure 105 of the aerosol canister 10 is connected to the second connecting structure 203 of the pressure compensating canister 20, the two male valves can be retractably connected, and in this way, the two male valves can be opened and connected to each other, so that the pressure compensating canister 20 can add the stored propellant into the aerosol canister 10 for the purpose of pressure compensating and aerating the aerosol canister 10. Furthermore, the receiving valve 104 and the releasing valve 202 can be freely selected and freely combined between the female valve and the male valve without intending to use other structures, particularly a cannula structure (belonging to the spraying device) to simultaneously open the receiving valve 104 and the releasing valve 202. It should be noted that the male valve and the female valve are well known in the art and therefore will not be described in detail.
In summary, in the spraying device of the embodiment of the present invention, the spraying can 10 can be reused, and the pressure supplementing can 20 continuously supplements the pressure to the spraying can 10 to inflate so as to reduce the risk that the spraying can 10 cannot spray and the pressure deficient spraying occurs, thereby improving the spraying efficiency and the spraying efficiency of the spraying can 10 when in use.
