Furthermore, the barrel cover 2 is provided with an inflation inlet 21 with a one-way stop valve, the inflation inlet 21 is provided with a pressure relief valve type pressure gauge formed by connecting a pressure gauge 220 and a pressure relief valve 221, when a garden manager fills pesticides into the portable telescopic garden pesticide sprayer, a valve port of the pressure relief valve 221 on the inflation inlet 21 is opened firstly, the air pressure in the telescopic barrel 1 is consistent with the external air pressure, the barrel cover 2 can be opened easily and safely, the pressure relief valve type pressure gauge can visually know the pressure in the barrel, and the risk that the barrel is exploded due to overhigh pressure in the barrel is avoided; the two ends of the handle 3 comprise a pair of upper handle nuts 81 and a pair of lower handle nuts 82, the upper handle nuts 81 are located on the upper side of the barrel cover 2 and used for adjusting the position of the barrel cover 2, and the lower handle nuts 82 are located on the lower side of the barrel bottom 5 and used for fixing the handle 3 on the barrel bottom 5.

Correspondingly, the portable telescopic garden pesticide sprayer can further adopt a pressurization method when spraying pesticides, and the pressurization method comprises the following steps:

s1, when the portable telescopic garden pesticide sprayer sprays pesticides, the pesticides are filled into the portable telescopic garden pesticide sprayer, the barrel cover 2 is buckled and sealed, gas is injected through the gas filling device 6, and then the pesticides are sprayed through the spray head 41;

s2, when the barrel is inflated, when the pressure value in the barrel is close to 0.15MPa, the barrel is stopped to be inflated, at the moment, the garden operator opens the spray head valve 42, and the spray head 41 sprays the pesticide;

s3, when the pressure value in the barrel is low, the spraying distance of the spray head 41 is shortened, at the moment, a garden operator can extrude the barrel cover 2 downwards, when the pressure value in the barrel is close to 0.15MPa again, the handle nut 81 is adjusted to the position of the barrel cover 2, so that the position of the barrel cover 2 is locked again by the handle nut 81, and the pressure in the barrel can continuously and effectively spray pesticide;

s4, repeating the step S3 until the pesticide in the barrel is sprayed, opening a valve of a pressure relief valve type pressure gauge, and repeating the steps S1 to S2 after the gas in the barrel is released, thereby completing the pesticide spraying task.

The pressurizing method can reduce or eliminate the process of injecting gas into the barrel through the gas filling device 6, and can still realize the pesticide spraying operation even without the gas filling device 6.

Further, the material of the telescopic barrel 1 is a waterproof cloth with an anti-seepage function.

Further, the handle 3 and the nut 8 are made of stainless steel.

Further, the hose 4 is made of a PVC plastic pipe with the length of more than 3 meters.
