[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Reference Figures 1 to 3 According to the binary packaging valve of the first embodiment of the utility model, the upper sealing seat 100, the valve seat 200 and the valve core assembly 300 are provided. The upper sealing seat 100 is used to be connected with the bottle body. The valve seat 200 is arranged at the bottom of the upper sealing seat 100. The valve seat 200 and the upper sealing seat 100 form a fluid channel 210. The valve seat 200 is made of hot-melt material. The valve seat 200 can be connected with the packaging bag by hot-melt welding. The valve core assembly 300 is arranged on the valve seat 200. The valve core assembly 300 can control the on-off of the fluid channel 210. The valve seat 200 can be connected to the corresponding packaging bag by hot-melt welding, and then connected to the bottle body by the upper sealing seat 100 to form a dual packaging can. The aerosol spray opening and closing can be controlled by the valve core assembly 300. Since the valve seat 200 is directly welded to the packaging, the traditional bow-tie connection seat and the corresponding sealing accessories can be saved, thereby reducing a component that requires sealing, improving product stability, reducing costs, making product assembly more convenient, and improving production efficiency.

[0029] Specifically, an upper sealing seat 100 is installed on the top of the valve seat 200. The valve seat 200 and the upper sealing seat 100 are provided with a fluid channel 210 for aerosol injection. The valve seat 200 can be made of a hot-melt material. The packaging bag can be a multi-layer aluminum platinum bag, and the inner layer can be a hot-melt material, so that the packaging bag can be directly hot-melt welded to the outer wall of the valve seat 200 to form a sealed space, thereby isolating the space inside the bag from the bottle body space. During specific use, the propellant amount of the bottle body can drive the aerosol in the packaging bag to spray outward from the fluid channel 210, and the user can control the valve core assembly 300 to control the injection of the aerosol. Since the valve seat 200 can be directly welded to the packaging bag, there is no need to set a traditional bow tie accessory, so the sealing member between the bow tie and the valve body does not need to be set, which can simplify the valve structure, reduce the number of components, and reduce manufacturing costs. At the same time, it is also easy to assemble and improve production efficiency. In addition, since a sealing structure is eliminated, the stability of the valve is also better.

[0030] Reference Figure 3In some embodiments of the present invention, the outer wall of the valve seat 200 is provided with a connection portion 220 for connecting to a packaging bag, and a spacing groove 230 is provided between the connection portion 220 and the fluid channel 210. The spacing groove 230 can protect the structure of the fluid channel 210 in the valve seat 200 during hot melt welding to keep the valve body in normal use.

[0031] Specifically, if the valve body is directly welded to the packaging bag, the valve body may be easily deformed due to the high temperature at the welding point, affecting the normal use of the valve body. By providing a spacing groove 230 between the connecting portion 220 and the fluid channel 210, the heat of welding can be blocked, and the deformation of the internal fluid channel 210 can be reduced to maintain the normal operation of the valve seat 200. In addition, since the spacing groove 230 is provided, even if the welding heat increases, it will not affect the internal structure of the valve seat 200. Therefore, the power of hot melt welding can be increased, the connection speed can be accelerated, and the production efficiency can be improved.
