[0027] A pneumatic assembly extending to the interior of the kettle body 2 is provided through the middle of the nozzle of the kettle cover spray seat 1, and the pneumatic assembly includes a pressure cylinder 9 installed in the middle of the nozzle of the kettle cover spray seat 1, a one-way air valve 11 is provided at the bottom of the cylinder tube of the pressure cylinder 9, and a pressure rod 5 is inserted into the cylinder tube of the pressure cylinder 9, and a pneumatic valve plate 10 is provided at the bottom end of the arm of the pressure rod 5. By pressing the combination of the pressure rod 5 and the pneumatic valve plate 10 up and down in a cycle, the air pressure in the pressure cylinder 9 is cyclically pressed and sent to the kettle body 2 through the one-way air valve 11, and air pressure is applied to the kettle body 2 as an air pressure source to push the inhibitor liquid pressure in the kettle body 2 out.

[0028] The upper end of the spray head of the pot cover spray seat 1 is provided with an opening and closing pressure relief component extending to the inside of the liquid outlet 6, and the liquid inlet end of the liquid outlet 6 is connected to a liquid outlet hose 8 extending to the inside of the pot body 2. The opening and closing pressure relief component includes an opening and closing pull rod 13 slidably connected to the pot cover spray seat 1 along the opening direction of the liquid outlet 6, one end of the arm of the opening and closing pull rod 13 is connected to a pressure handle 4 buckled on the pot cover spray seat 1, and the other end of the arm of the opening and closing pull rod 13 is provided with an opening and closing push head 14, and the outer side of the arm of the opening and closing pull rod 13 is provided with a compression spring 12 pressed against the pot cover spray seat 1, and by pressing the pressure handle 4 , pull the opening and closing rod 13 to slide, remove the opening and closing push head 14 from the opening and closing through hole 74 of the opening and closing valve head 73, so that the nozzle assembly 7 remains in the conducting state, and then under the action of gas pressure, the inhibitor liquid in the kettle body 2 is pushed out through the liquid outlet hose 8 and sprayed out through the nozzle assembly 7 to spray the inhibitor liquid on the tobacco buds. After spraying, release the pressing handle 4, use the compression spring 12 and the opening and closing rod 13 to reset the combination, and press the opening and closing push head 14 again on the opening and closing through hole 74, cut off the inhibitor flow channel, and perform quantitative spraying on the tobacco buds.

[0029] A holding handle 3 is provided on one side of the spray head of the pot cover spray seat 1, and a liquid outlet 6 is provided on the other side of the spray head of the pot cover spray seat 1. The nozzle of the liquid outlet 6 is installed with a nozzle assembly 7. The nozzle assembly 7 includes a screw-on screw sleeve 71, and a liquid outlet pipe 72 is provided through the middle of the support of the screw-on screw sleeve 71.
