[0031] The foam residue cleaning component 2 includes a liquid inlet connecting pipe 201 fixed on the top of the top connecting ring 104, the side of the liquid inlet connecting pipe 201 is connected to an external foam hose 202, the top threaded sleeve of the liquid inlet connecting pipe 201 is provided with a top fixing ring 203, the inner wall of the top fixing ring 203 is provided with an inner wall thread 204, an air pump 205 is provided above the top fixing ring 203, the bottom end of the air pump 205 is connected to a fixed base 206, the outer side of the bottom end of the fixed base 206 is provided with a first connecting thread 207, the output end of the bottom end of the air pump 205 is connected to two gas delivery pipes 208, and the bottom end of the gas delivery pipe 208 passes through the bottom end of the fixed base 206.

[0032] The tube body limiting assembly 3 includes a limiting connecting plate 301, on which two limiting plug holes 302 are symmetrically provided. The foam spray gun barrel 101 passes through the limiting plug holes 302. Two side screw holes 303 are symmetrically provided on both sides of the limiting connecting plate 301, and interference screws 304 are inserted in the side screw holes 303.

[0033] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the side of the bottom end of the foam spray gun barrel 101 is provided with an external thread, the side of the top end of the output gun barrel head 102 is provided with an external thread, and the foam spray gun barrel 101 and the output gun barrel head 102 are both inserted into the connecting screw sleeve 103.

[0034] This makes the connection and disassembly between the foam spray gun barrel 101 and the output gun barrel head 102 and the connecting screw sleeve 103 more convenient.

[0035] Embodiment 3: The difference between this embodiment and embodiment 1 is that, the top end of the liquid inlet connecting pipe 201 is provided with an external thread, and the top fixing ring 203 is connected to the top end of the liquid inlet connecting pipe 201 through a thread.

[0036] This makes the connection and disassembly between the air pump 205 and the liquid inlet connecting pipe 201 more convenient.

[0037] Embodiment 4: The difference between this embodiment and embodiment 1 is that the end of the side screw hole 303 is connected to the inner wall of the limiting plug hole 302 .

[0038] This allows the end of the abutting screw 304 inserted into the side screw hole 303 to better abut against the outer wall of the foam spray gun barrel 101 .

[0039] In this embodiment, due to the muzzle of the existing double-gun high-pressure polyurethane foaming machine, some foam plastic often remains at the muzzle after the polyurethane foam plastic is sprayed. If it is not cleaned in time, the muzzle will be blocked after the plastic solidifies, thereby affecting the next polyurethane foam plastic spraying construction.

[0040] In summary, in a specific implementation, the detachable barrel assembly 1 is arranged in a detachable structure, an output barrel head 102 is arranged at the bottom end of the foam spraying barrel 101, and the output barrel head 102 is threadedly connected to the foam spraying barrel 101 through a connecting screw sleeve 103, so that the polyurethane foam remaining in the output barrel head 102 can be easily cleaned.

When the foam spraying in the foam spraying gun barrel 101 and the output gun barrel head 102 is completed, the user can start the air pump 205 so that the high-pressure airflow generated by the air pump 205 can be transported to the liquid inlet connecting pipe 201 through the gas delivery pipe 208, and then blow a strong airflow from the liquid inlet connecting pipe 201 to the foam spraying gun barrel 101 and the output gun barrel head 102.

[0043] The foam liquid remaining in the foam spray gun barrel 101 and the output gun barrel head 102 can be blown out by the strong airflow generated by the air pump 205 before solidification, so that the foam residual liquid remaining in the detachable barrel component 1 can be cleaned quickly and conveniently, thereby avoiding the foam residual liquid remaining in the detachable barrel component 1 not being able to be cleaned in time, ensuring that the detachable barrel component 1 can be in a normal operating state, and making the construction work more convenient for users.
