As shown in Figs. 1-2, a kind of chemical reagent bottle of the utility model, including bottle body 100, are in the form of a column cylindrical shape, one end
With opening, opening is provided with sampler 140.100 upper end of bottle body is provided with Bottle cap 130, the covering sampling of Bottle cap 130
Device 140 is arranged.The bottom of bottle body 100 is provided with venthole 120, bottle body 100 is internally provided with closed piston plate 110, living
The outer edge of seben 110 and the inner wall of bottle body 100 fit closely, and can slide up and down along inner wall, the lower section of piston plate 110
Space is connected to venthole 120.
It is illustrated in figure 2 the structure chart of sampler 140.140 specific structure of sampler are as follows: (one end) bottom of sample storing device 140a
Portion is arranged in bottle body 100, and the other end extends to outside opening, and sample storing device 140a is slidably sleeved in the opening.It is storing
The outer wall of sample device 140a is provided with the first injection port 143, is connected to inside the first injection port 143 and bottle body 100.In sample storing device 140a
It is inside coaxially arranged with conduit 141, conduit upper end extends to outside sample storing device 140a, and the word of lower end four is in the sample storing device 140a
It is interior, and spring 145 is provided at lower end, the lower end of spring 145 is against the bottom of bottle body 100.The top of spring 145 is arranged
Lower baffle plate 147, lower baffle plate 147 are set in outside conduit 141.Second injection port is set on conduit 141 above lower baffle plate 147
148.Overhead gage 146 is set in the top of conduit 141, piston 142, piston are provided between overhead gage 146 and lower baffle plate 147
142 external margins are close to sample storing device 140a inner wall, and can slide up and down.The piston 142 is up and down along the conduit 141
Second injection port 148 can be made to open and close.Ball valve 144 is provided at the first injection port 143.
It is located at external one end side wall in conduit 141 and is provided with outlet 150, pressure cap 149 is arranged in top.Bottle body and piston
It is made of polythene material.
Piston 142 is placed between the lower baffle plate 147 and overhead gage 146 of conduit.Between lower baffle plate 147 and overhead gage 146
Apart from moderate.When piston 142 is moved to overhead gage 146, piston 142 exposes the second injection port 148 on conduit 141；When
When piston 142 is moved to lower baffle plate 147, piston 142 closes the second injection port 148 on conduit 141.Piston 142 and storage sample
Device 140a constitutes closed unit room (the first injection port 143 and 144 close contact of ball valve at this time).Spring upper end connects with lower baffle plate 147
Touching, lower end and end in contact under sample storing device 140a (but 145 lower end of spring is not contacted with ball valve 144, between holding 3-5mm distance, bullet
145 aperture of spring is less than 144 diameter of ball valve).Pressure cap is arranged in the sample outlet position of conduit 141, and outlet 150 can be such that sample flows out.
It is closed plug 151 be placed in sample storing device 140a it is suitable for reading in, be on the one hand able to maintain conduit 141 and freely up and down move；On the other hand it is used for
It is fixed on sampler is closed in chemical reagent bottle body.First injection port, 143 diameter is slightly less than 144 diameter of ball valve.
When not taking chemical reagent, Bottle cap 130 is covered；Venthole 120 is covered with Capsule；
When taking chemical reagent, 120 Capsule of venthole, Bottle cap 130 are sampled again after removing.
Working principle: the piston plate 110 in bottle body 100 is placed in 100 bottom of bottle body, and a certain amount of sample is added in bottle body 100.
The sampler 140 of Fig. 2 is placed in bottle body 100.When sampling, by lower pressing cap 149, spring 145 is compressed, and piston 142 moves to
Baffle 146 exposes the second injection port 148 on conduit 141.Due to when piston 142 moves down ball valve 144 by the first injection port
143 close, and pressure increases in sample storing device 140a, and the chemical reagent in sample storing device 140a (is initially air, being after Repeated Compression
Learn reagent) enter conduit 141 via the outflow of conduit outlet.Pressure cap 149 is decontroled, spring 145 bounces.Piston 142 moves to lower block
Plate 147, supravasal second injection port 148 are closed, and pressure reduces to form negative pressure in sample storing device 140a, and ball valve 144 is to moving up
Dynamic to separate with the first injection port 143, chemical reagent enters in sample storing device 140a in bottle body 100.Due to the chemistry examination in bottle body 100
After agent enters sample storing device 140a, the pressure in bottle body 100 reduces, and the piston plate 110 in bottle body 100, which moves up, to be made inside and outside bottle body
Pressure is consistent.By such repetitive process, the chemical reagent in bottle body 100 is removed.According to the graduation mark on bottle body 100
It can determine taking-up volume of sample.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
