Specifically, the aerosol container 11 has an opening 111, and the first valve assembly 12 is detachably mounted on the aerosol container 11, and is used to seal the opening 111 when mounted on the aerosol container 11, and to make the inside of the aerosol container 11 communicate with the outside through the opening 111 when removed from the aerosol container 11, so that the functional liquid material (aerosol) can be replenished into the aerosol container 11 through the opening 111. One of the first valve assembly 12 and the propellant replenishing device 2 is provided with a groove structure 5, and the other is provided with a convex structure 4, which is used for connecting the aerosol container 11 and the propellant replenishing device 2 through the groove structure 5 and the convex structure 4 when the first valve assembly 12 is installed on the aerosol container 11, so that the propellant in the propellant replenishing device 2 is replenished into the aerosol container 11. The first valve assembly 12 is also used to detachably connect the spray head 13 through the convex structure 4 or the groove structure 5, so that when the first valve assembly 12 is installed on the aerosol container 11, under the action of the spray head 13, the spray head 13 is connected with the inside of the aerosol container 11, so that the aerosol in the aerosol container 11 is driven by the parabolic agent and sprayed out from the spray head 13.

[0036] The method of using the utility model is as follows: when the aerosol in the aerosol container 11 is used up, the first valve assembly 12 is disassembled from the aerosol container 11, and functional materials (such as cleaning agents, etc.) are added to the aerosol container 11 through the opening 111, and the first valve assembly 12 is reinstalled, and the nozzle 13 is disassembled from the first valve assembly 12, and the first valve assembly 12 is connected to the external propellant replenishing device 2 through the groove structure 5 and the convex structure 4, so that the aerosol container 11 is connected to the propellant replenishing device 2, and the propellant replenishing device 2 can be inverted and pressed downward at this time, so that the propellant (such as liquefied petroleum gas, dimethyl ether, etc.) in the propellant replenishing device 2 is injected into the aerosol container 11, and the injection is stopped after a certain amount of propellant is injected, and the connection between the first valve assembly 12 and the propellant replenishing device 2 is disconnected, and the nozzle 13 is reinstalled on the first valve assembly 12, and the aerosol spraying device 1 can be used again.

[0037] It can be understood that the utility model realizes the function of replenishing aerosol functional materials and propellants into the aerosol container 11 based on the detachable design between the first valve component 12 and the aerosol container 11, and the docking connection between the first valve component 12 and the propellant replenishing device 2 through the groove structure 5 and the protrusion structure 4, so that the aerosol container 11 and the propellant replenishing device 2 are connected, so that the aerosol container 11 can be reused, the use cost is reduced, and the environmental pollution is reduced. In addition, different types of functional materials can be added to the aerosol container 11 to realize different functions of the aerosol product, such as cleaning, polishing, air purification, facial moisturizing, etc., with good flexibility.

[0038] In a specific embodiment, please refer again to Figures 1 to 3 The first valve assembly 12 includes a sealing portion 7 for sealing the opening 111 and a connecting portion 8 for connecting the spray head 13 and the propellant replenishing device 2. The sealing portion 7 is detachably connected to the aerosol container 11. Optionally, the sealing portion 7 can be detachably connected to the aerosol container 11 by any one of threaded connection, quick plug connection and snap connection. The connecting portion 8 is movably connected to the sealing portion 7. The groove structure 5 or the protrusion structure 4 is arranged on the connecting portion 8. The connecting portion 8 connects the spray head 13 and the propellant replenishing device 2 through the groove structure 5 or the protrusion structure 4. When the propellant replenishing device 2 is connected, the propellant in the propellant replenishing device 2 is injected into the aerosol container 11 through the connecting member 8. When the spray head 13 is connected, the connecting portion 8 is used to move relative to the sealing portion 7 under the action of the spray head 13 to achieve communication between the spray head 13 and the inside of the aerosol container 11.

[0039] In a specific embodiment, please refer to Figure 1 and Figure 3 The sealing portion 7 includes a valve cup 121 , the connecting portion 8 includes a first valve stem 122 , and the first valve assembly 12 also includes an elastic return member 123 and a valve chamber 124 .

[0040] Specifically, the valve cup 121 is detachably connected to the aerosol container 11 for sealing the opening 111 of the aerosol container 11. Optionally, the valve cup 121 can be detachably connected to the aerosol container 11 by any one of a threaded connection, a quick-insert connection and a snap-on connection. Preferably, refer to Figure 1The valve cup 121 and the side wall of the opening 111 are provided with matching thread structures 3, and the two are detachably connected through the thread structure 3, and the sealing is good. A valve stem seal 9 is provided in the valve cup 121, and the first valve stem 122 is movably provided in the valve cup 121, and a valve hole 1222 is provided in the first valve stem 122. The valve chamber 124 is connected to the valve cup 121, and an elastic reset member 123 is provided in the valve chamber 124. Optionally, the elastic reset member 123 includes but is not limited to a spring. The groove structure 5 or the protrusion structure 4 is arranged at one end of the first valve stem 122. The first valve stem 122 is detachably connected to the nozzle 13 through the groove structure 5 or the protrusion structure 4. The other end of the first valve stem 122 is connected to the elastic reset member 123. The first valve stem 122 is used to move toward the valve chamber 124 under the action of the nozzle 13 (pressing the nozzle 13 drives the first valve stem 122 to move). After the first valve stem 122 moves, the valve stem seal 9 releases the seal on the valve hole 1222 on the valve stem 122, thereby connecting the nozzle 13 with the inside of the aerosol container 11 and compressing the elastic reset member 123. The elastic reset member 123 is used to drive the first valve stem 122 to move toward the valve cup 121 after the action of the nozzle 13 on the first valve stem 122 disappears. The valve stem seal 9 re-seals the valve hole 1222 on the valve stem 122, thereby cutting off the connection between the nozzle 13 and the inside of the aerosol container 11.

[0041] In this embodiment, when the nozzle 13 is not pressed, the first valve stem 122 is in a position where the valve stem seal 9 seals the valve hole 1222 on the valve stem 122 and disconnects the nozzle 13 from the inside of the aerosol container 11 due to the elastic force of the elastic reset member 123. When the aerosol needs to be sprayed, the nozzle 13 is pressed to drive the first valve stem 122 to move. After the movement, the first valve stem 122 compresses the elastic reset member 123, and the valve stem seal 9 releases the seal of the valve hole 1222 on the valve stem 122. The nozzle 13 is connected to the inside of the aerosol container 11. Under the pressure of the propellant in the aerosol container 11, the aerosol functional material is finally sprayed to the outside through the guide member 6, the valve chamber 124, the valve hole 1222 of the first valve stem 122 and the nozzle 13. After the influence of the spray head 13 on the first valve stem 122 disappears, the first valve stem 122 returns to its original position due to the elastic force of the elastic reset member 123, and the valve stem seal 9 seals the valve hole 1222 on the valve stem 122 again, disconnecting the spray head 13 from the inside of the aerosol container 11 again, and the cycle continues.

[0042] In one embodiment, the valve stem seal 9 is a valve stem seal ring 1221, a seal groove 1223 matching the valve stem seal ring 1221 is formed on the first valve stem 122, and the valve hole 1222 is located in the seal groove 1223. Specifically, the valve stem seal ring 1221 is used to seal the valve hole 1222 when it is embedded in the seal groove 1223, so as to cut off the communication between the spray head 13 and the inside of the aerosol container 11. The valve stem seal ring 1221 is also used to release the seal of the valve hole 1222 when leaving the seal groove 1223, so as to achieve the communication between the spray head 13 and the inside of the aerosol container 11.

[0043] Further, refer to Figure 2 The propellant replenishing device 2 may include a propellant container 21, and a second valve assembly 22 disposed on the propellant container 21. The second valve assembly 22 may include a second valve stem 221. The protrusion structure 4 is disposed on the second valve stem 221. The propellant container 21 is connected to the groove structure 5 through the protrusion structure 4 of the second valve stem 221, thereby achieving communication with the aerosol container 11. In one embodiment, the groove wall spacing of the groove structure 5 on the first valve stem 122 gradually decreases in the direction away from the spray head 13, for example, Figure 3 In the trapezoidal groove structure, the shape of the protruding structure 4 is adapted to the groove structure 5. The protruding structure 4 and the groove structure 5 in this embodiment can better realize the positioning function, and the connection stability is higher.

[0044] For further information, please refer to Figures 3 to 5 The valve cup 121 is also provided with a valve cup sealing ring 1211 , and the valve cup sealing ring 1211 is used to achieve a sealed connection between the valve cup 121 and the aerosol container 11 when the valve cup 121 is connected to the aerosol container 11 , thereby improving the air tightness of the aerosol container 11 .

[0045] In a specific embodiment, referring to Figure 1 and Figure 3 The aerosol container 11 is further provided with a guide member 6, one end of which is connected to the interior of the aerosol container 11, and the other end of which is connected to the valve chamber 124. Optionally, the guide member 6 includes but is not limited to a liquid guide tube.

[0046] In a specific embodiment, the nozzle 13 is an atomizing nozzle, and the aerosol sprayed can form an aerosol state under the action of the atomizing nozzle, and the spraying is more uniform. In a specific embodiment, the aerosol container 11 and the propellant container 21 can include any one of a metal container, a glass container and a plastic container, which is not specifically limited here.

[0047] In summary, the utility model is a reusable aerosol device, which realizes the function of replenishing aerosol and propellant into the aerosol container 11. The aerosol container 11 can be reused, which reduces the cost of use and reduces environmental pollution. In addition, different types of functional materials can be added to the aerosol container 11 to realize different functions of aerosol products, which is highly flexible. Specifically, in terms of replenishing aerosol functional materials, the function of disassembling the first valve component 12 to replenish the aerosol after the aerosol is used up is realized mainly through the detachable design between the first valve component 12 and the aerosol container 11. In terms of replenishing the parabolic agent, the nozzle 13 is mainly disassembled to connect the first valve component 12 with the propellant container replenishing device 2 through the groove structure 5 and the protrusion structure 4, so as to replenish the propellant into the aerosol container 11, which has a good user experience.
