High-pressure spray can

Abstract

The invention relates to a high-pressure spray can, which comprises a can body, a valve assembly, a hose, a balance weight piece and a hard pipe. The valve assembly is arranged on the can body and can communicate the inside and the outside of the can body; the two ends of the hose are connected with the valve assembly and the balance weight piece respectively, and the balance weight piece enables the tail end of the hose to automatically move towards the space in the ground direction. The hard pipe is sleeved outside the hose, and the length of the hard pipe exceeds half of the height of the can body; the hose downwards protrudes out of the hard tube; therefore, when the can body is inclined or horizontal, the balance weight piece can enable the tail end of the hose to automatically move towards the liquid position in the high-pressure spray can so as to keep being immersed in the liquid, and then the liquid can still be sprayed in the inclined or horizontal state. The hard pipe can properly limit the bending amount of the hose, so that the water suction opening of the hose penetrating through the balance weight piece is quickly positioned in the liquid.

Description

technical field [0001] The invention relates to a liquid agent container capable of containing and spraying a product, especially a spray tank which can be filled with a liquid agent and a propellant inside, and the liquid agent is sprayed out by the propellant. Background technique [0002] see Figure 9 and Figure 10 As shown, the high-pressure spray tank used for spraying product liquid in the known technology, such as spray insecticide or defense pepper spray tank or the like, has a tank body 91, a valve assembly 92, a suction pipe 93 and a shower head 94; The top of the tank body 91 has a crimp opening; the valve assembly 92 is sealed and fixed on the crimp opening of the tank body 91; the head end 931 of the suction pipe 93 installed in the tank body 91 communicates with the valve assembly 92, and the tail end 932 Adjacent to the bottom of the tank body 91; when the spray tank is in use, the liquid agent A and the propellant (such as compressed gas) filled in the tan...

Problems solved by technology

[0008] see Figure 14 to Figure 16 As shown, but when the capacity of liquid agent A in the tank is only half or less, and the nozzle 941A of the nozzle 94A on the top of the spray tank held by the hand is inclined towards the direction of the ground, or when it is used in a horizontal state, then Because the suction port of the suction pipe 93A cannot be submerged in the liquid agent A in the tank, even if there is still liquid agent A residue in the tank at this time, when the nozzle 94A is pressed or the trigger 971 of the spray gun 97 is pressed, it will not be able to Spray liquid agent A in the tank
