A disinfection method of a special-shaped contact disinfection sprayer for preventing and treating new coronavirus comprises the following specific steps:

when an uneven object or space needs to be disinfected, the main spray pipe drives all the needle-shaped sliding pipes to abut against the object or the space, so that the needle-shaped sliding pipes contacting with the convex positions slide towards the direction close to the main spray pipe relative to the connecting flat plate due to extrusion, the connected corrugated expansion pipes shrink, and the needle-shaped sliding pipes at other positions penetrate into the concave positions, so that irregular special-shaped surfaces are fully contacted;

secondly, starting a delivery pump to enable disinfectant in the storage box to be transmitted into the pressurizing box body, simultaneously, arranging all small hydraulic telescopic rods for stretching, carrying a pressurizing block to extrude towards the middle of the inner side of the pressurizing box body when the small hydraulic telescopic rods stretch, so that the disinfectant in the pressurizing box body is pressurized to flush into the main spray pipe, then flows into the needle-shaped slide pipes at all positions from the corrugated telescopic pipes at all positions, forms atomized spray to contact with objects with different shapes or side walls of corresponding spaces under the action of an atomizing spray head for efficient disinfection, and slides back and resets under the action of resilience force of a first spring when the needle-shaped slide pipes are separated from the contacts;

thirdly, the small hydraulic telescopic rod extends, when the pressurizing block is driven to pressurize the pressurizing box body, the pressurizing block drives the piston block to slide towards the direction close to the inner side of the main spray pipe through the linkage frame, so that the tail end port of the recovery suction pipe is sucked by the piston barrel, water mist diffused when the needle-shaped sliding pipe atomizes the disinfectant is sucked away, the recovered water mist enters the piston barrel along the recovery suction pipe, the water mist is blocked by a gathering blocking piece when entering the piston barrel and then gathered into water drops and flows in the piston barrel, when the piston block moves to the diversion flaring inclined plate, a communication position appears below the piston block, and the gathered disinfectant flows into the main spray pipe from the position of the diversion flaring inclined plate to realize recovery;

fourthly, in the process, the piston block pushes the sealing block to compress the second spring and leans against the inner side of the main spray pipe, finally, the sealing block moves to the position of the movable stop block and drives the bending clamping block to extrude to penetrate through the position of the movable stop block, when the small hydraulic telescopic rod drives the pressing block to contract, the pressing block drives the piston block to return to slide and reset through the linkage frame, the bending clamping block at the lower end of the sealing block is hooked on the movable stop block, the movable stop block cannot rotate in the direction close to the recovery suction pipe, so that the sealing block is fixedly clamped at the end of the piston cylinder close to the main spray pipe, when the piston block returns to slide and reset, the air holes are in the ventilation state, the phenomenon that the piston block extrudes into the recovery suction pipe to cause the atomized disinfectant to be sprayed out is avoided, and when the piston block moves to the position of the convex sliding block, the convex sliding block is pushed to slide in, the convex sliding block pulls the steel wire, the steel wire pulls the connecting sliding block downwards through the steering of the fixed pulley, so that the movable stop block moves downwards to be separated from the bent stop block, the sealing block is reset and attached to the air hole under the action of the resilience force of the second spring, and the piston block can conveniently generate negative pressure when sliding towards the direction of the main nozzle next time;

fifthly, when a certain point or a small area needs to be disinfected by concentrated injection, the annular handle outside the main spray pipe is rotated to drive the magnet to rotate around the concave thin ring, and the iron block rotates along with the magnet under the action of magnetic force due to attraction between the magnet and the iron block, so that the rotating rod rotates, the rotating ring at the bottom of the rotating rod rotates along with the rotating rod, the folded fan-shaped folding pieces are unfolded to shield the screen leakage plate, and disinfectant in the main spray pipe can only flow to the needle-shaped slide pipe at the central position from the single hole at the central position, so that the disinfectant can be sprayed out from the needle-shaped slide pipe at the single position.

Compared with the prior art, the invention has the beneficial effects that:

1. when the invention needs to contact with an uneven object or space, the main spray pipe drives all the needle-shaped sliding pipes to be abutted against the object or space, so that the needle-shaped sliding pipes contacting with the convex position slide towards the direction close to the main spray pipe relative to the connecting flat plate due to extrusion, the connected corrugated expansion pipe is contracted, the needle-shaped sliding pipes at other positions are inserted into the concave position, the irregular special-shaped surface is fully contacted, and the corrugated expansion pipe is rejected to keep all the needle-shaped sliding pipes communicated with the main spray pipe;

2. when the small hydraulic telescopic rod extends and is pressurized with the pressurizing block, the pressurizing block drives the piston block to synchronously slide, so that the piston cylinder enables the tail end port of the recovery suction pipe to suck air, water mist diffused when the needle-shaped sliding pipe atomizes disinfectant is sucked away, the disinfectant water mist entering the piston cylinder is gathered into water drops when contacting with the gathering baffle, and the gathered disinfectant flows into the main spray pipe from the position of the diversion flaring inclined plate when the piston block moves to the diversion flaring inclined plate, so that the recovery is realized;

3. when the piston block pushes the sealing block to move to the position of the movable stop block, the bending clamping block on the sealing block is extruded to penetrate through the position of the movable stop block, and when the piston block slides back and resets, the sealing block is clamped at the position of the movable stop block through the bending clamping block, so that the air holes in the piston block are in a ventilation state, atomized disinfectant entering a recovery suction pipe is prevented from being sprayed out due to the fact that the piston block extrudes towards the recovery suction pipe, and when the piston block moves to the position of the convex sliding block, the convex sliding block pulls a steel wire, the movable stop block moves downwards to be separated from the bending clamping block, so that the sealing block resets and is attached to the air holes under the action of the resilience force of the second spring, and negative pressure is conveniently generated when the piston block slides towards;

4. when a certain point or a small area needs to be disinfected by concentrated injection, the magnet rotates around the concave thin ring by rotating the annular handle outside the main spray pipe, and the iron block rotates along with the magnet under the action of magnetic force due to attraction between the magnet and the iron block, so that the rotating rod rotates, the rotating ring at the bottom of the rotating rod rotates along with the rotating ring, the folded fan-shaped folding pieces are unfolded to shield the screen plate, and disinfectant in the main spray pipe can only flow to the needle-shaped slide pipe at the central position from the single hole at the central position, so that the disinfectant can be sprayed out from the needle-shaped slide pipe at the single position.
