[0002] The high and low pressure automatic balancing structure at the bottom of the pesticide packaging barrel is mainly used to ensure the stability of the pressure in the barrel during the storage, transportation and use of pesticides, so as to prevent the packaging from rupture or leakage due to excessive pressure;

[0003] After checking the publication number: CN219905354U, a plastic packaging barrel with internal negative pressure self-balancing is disclosed. This technology discloses "a plastic packaging barrel with internal negative pressure self-balancing, including a barrel body, a handle assembly is provided on the outer surface of the barrel body, an anti-slip sleeve is provided on the handle assembly, a top cover is threadedly connected to the top of the barrel body, a disassembly assembly is provided on the top cover, and a one-way valve is provided on the disassembly assembly; the disassembly assembly includes a mounting seat fixed to the upper surface of the top cover, threaded holes are provided at both ends of the mounting seat, studs are threadedly connected in the threaded holes, hand wheels are fixed at the opposite ends of the two studs, and a card is rotatably connected at the opposite ends of the two studs" and other technical solutions, which have "the plastic packaging barrel with internal negative pressure self-balancing, by providing a disassembly assembly on the top cover, the one-way valve is located in the disassembly assembly, the disassembly assembly can quickly disassemble and assemble the one-way valve, the operation is simple, and it is convenient to maintain it, and the one-way valve can discharge the pressure in the barrel body, so as to achieve its internal negative pressure self-balancing, and it is easy to use" and other technical effects;

[0004] In the above scheme, a one-way valve is installed on the barrel cover to achieve self-balancing of the negative pressure in the barrel. In order to save space during storage or transportation, the packaging barrels are often stacked up, which causes the packaging barrels located above to inevitably directly squeeze the one-way valve on the lower packaging barrel under the action of gravity; this squeezing may affect the normal function of the one-way valve, thereby affecting the self-balancing effect of the negative pressure in the packaging barrel.
