specifically, as shown in fig. 1, fig. 2 and fig. 5, when using the mechanism, firstly, an operator presses the rubber dropper head 503 to deform the rubber dropper head 503 into the bottle body 1, and then the air in the rubber dropper head 503 is flushed into the bottle body 1, and then the operator releases the rubber dropper head 503 to make the pesticide raw liquid in the bottle body 1 flush upwards through the graduated dropper 502 until the pressure in the bottle body 1 is the same as that in the rubber dropper head 503, and then the flushing is stopped, and because the outside wall of the graduated dropper 502 is provided with a scale value, the volume of the pesticide raw liquid in the graduated dropper 502 can be clearly observed, so that the ratio between pesticide and water is more accurate.

The top end of the interior of the graduated dropper 502 is fixedly connected with a corrosion-resistant structure 6, the corrosion-resistant structure 6 comprises a sealing ring 601, an isolation plug 602 and vent holes 603, the outer side wall of the sealing ring 601 is fixedly connected with the top end of the inner side wall of the graduated dropper 502, the inner side wall of the sealing ring 601 is fixedly connected with the isolation plug 602, the vent holes 603 are formed in the isolation plug 602, the cross-sectional area of the outer diameter of the sealing ring 601 is the same as that of the inner diameter of the graduated dropper 502, and the vent holes 603 are distributed in the isolation plug 602 at equal intervals;

specifically, as shown in fig. 1, 3 and 4, when the mechanism is used, firstly, when the mist volatilized from the pesticide stock solution enters the arc-shaped groove 501 and continues to rise, the mist enters the inside of the vent hole 603 and gradually condenses at the corner inside the vent hole 603 due to the fact that the vent hole 603 is a bent hole, and then becomes liquid drops, the mist becomes liquid drops and cannot continue to rise, and therefore the damage of the volatilized toxic pesticide gas to the metering product is prevented;

the bottom end of the graduated dropper 502 is fixedly connected with a lengthening structure 7, the lengthening structure 7 comprises a connecting plug 701, an external dropper 702 and a lengthening pipette 703, the graduated dropper 502 penetrates through the connecting plug 701, the external dropper 702 is fixedly connected to the outer side wall of the connecting plug 701, the lengthening pipette 703 is fixedly connected to the bottom end of the external dropper 702, the cross-sectional area of the inner diameter of the connecting plug 701 is the same as that of the outer diameter of the graduated dropper 502, and the bottom end of the lengthening pipette 703 and the bottom end of the graduated dropper 502 are in the same vertical plane;

specifically, as shown in fig. 1 and 5, when using this mechanism, first, the extension structure 7 is connected to the bottom end of the outer side wall of the graduated dropper 502, the graduated dropper 502 is vertically inserted into the external dropper 702 and is pressed down with force, the connecting plug 701 is tightly attached to the outer side wall of the graduated dropper 502, and the graduated dropper 502 is made to grow in phase, so that the graduated dropper 502 can suck the pesticide in a shallow position in the bottle body 1.

The working principle is as follows: firstly, when the measuring bottle is used, pesticide stock solution is poured into the interior of a bottle body 1 through a bottle opening 2, then a bottle plug 4 and a metering structure 5 inside the bottle plug are inserted into the interior of the bottle opening 2, when a quantitative pesticide stock solution needs to be taken out, an operator presses a rubber dropper head 503, the pesticide stock solution in the bottle body 1 can upwards flow in through an internal channel of a graduated dropper 502, the inflow is stopped until the pressure in the bottle body 1 is the same as that in the rubber dropper head 503, and the pesticide stock solution is stopped in the graduated dropper 502.

When the pressure of the rubber dropper head 503 is too high, the pesticide stock solution is excessively pumped, so that the arc-shaped groove 501 is arranged and can be used as a buffer to prevent the rubber dropper head 503 from being corroded due to the fact that the liquid rises too fast due to too high force.

Because the outer side wall of the graduated dropper 502 is provided with the scale interval, the volume of the pesticide stock solution in the graduated dropper 502 can be clearly observed, then the bottle stopper 4 and the metering structure 5 in the bottle stopper 4 are taken out from the inside of the bottle opening 2, the graduated dropper 502 is placed in the pesticide proportioning container, and the rubber dropper head 503 is pressed again to enable the equal amount of the pesticide stock solution in the graduated dropper 502 to be dripped into the pesticide proportioning container;

secondly, with the continuous extraction of the pesticide stock solution in the bottle body 1 by the metering structure 5, the pesticide stock solution in the bottle body 1 is gradually reduced, and after the solution in the bottle body 1 is reduced to a certain degree, the metering structure 5 is difficult to extract the solution in the bottle body 1, so that the bottom end of the outer side wall of the graduated dropper 502 is connected with the lengthening structure 7, the graduated dropper 502 is vertically inserted into the external dropper 702 and pressed downwards with force, the connecting plug 701 is tightly attached to the outer side wall of the graduated dropper 502, the graduated dropper 502 is made to grow in a phase-changing manner, at the moment, the graduated dropper 502, the external dropper 702 and the lengthening dropper 703 are inserted into the bottle body 1, and after the lengthening dropper 703 is inserted into the pesticide stock solution in the bottle body 1, the rubber dropper head 503 is pressed for extraction;

finally, after the measuring bottle is used, the bottle plug 4 and the measuring structure 5 inside the bottle plug can be directly sucked into the bottle opening 2 for storage, because the pesticide raw liquid inside the bottle body 1 contains a large amount of toxic substances, the pesticide raw liquid can volatilize along with time due to the volatilization property of the liquid, the volatilized mist can enter the arc-shaped groove 501 along the inside of the scale dropper 502 and then continuously ascend, because the rubber dropper head 503 is made of rubber and is easy to corrode, a layer of sealing ring 601 is fixed at the top end inside the arc-shaped groove 501, an isolating plug 602 is fixed inside the sealing ring 601, when the volatilized mist of the pesticide raw liquid enters the arc-shaped groove 501 and continuously ascends, the mist can only ascend through the sealing ring 601 due to the fact that the sealing ring 601 blocks a gap between the isolating plug 602 and the arc-shaped groove 501, the mist can be contacted with the bottom end of the sealing ring 601 and be condensed into liquid drops when the mist ascends, and then drops back to the arc-shaped groove 501, the remaining small part of mist can gush into the vent hole 603, and because the vent hole 603 is a bent hole, the mist can be gradually condensed in the vent hole 603 after entering the vent hole 603 and then becomes liquid drops, so that the mist cannot continuously rise, and the insecurity caused by volatilization is avoided.

The scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
