Abstract
The utility model discloses a microdrop washing bottle for chemical test, which comprises a plastic narrow-mouthed bottle body (1) and a bottle cap (2), wherein the bottle cap (2) covers the mouth of the plastic narrow-mouthed bottle body (1). The washing bottle is characterized in that a water storage cavity (7) is formed at the upper part of the bottle cap (2) and communicated with a faucet (6) on the side wall at the upper part of the bottle cap (2); a suction pipe (3) is fixed at the bottom of the bottle cap (2) and communicated with the water storage cavity (7); a control valve (5) is arranged at the middle part of the bottle cap (2) at the upper opening of the suction pipe (3); and an elastic arc-shaped wall (8) is arranged on the upper wall of the bottle cap (2). The utility model has the advantages of simple structure, convenient use and large liquid storage amount, can conduct microdrop under the test, save the test time, improve the test efficiency, and reduce the work intensity for testers.
Description
Technical field
The utility model relates to a kind of improvement of wash bottle, specifically a kind of chemical test droplet wash bottle.
Background technology
Distilled water is absolutely necessary in chemical test, is used to wash instrument, dilution, dissolving and constant volume etc.In chemistry laboratory, wash bottle is a kind of container that is usually used in holding distilled water, and is furnished with the device of the thin liquid stream of emission.At present, what use always in the laboratory is the extrusion pressing type wash bottle, is made up of the outlet pipe of plastics narrow-mouthed bottle body and bottleneck device.In liquid constant volume test, liquid level can add with wash bottle before one centimetre of graduation mark in the volumetric flask, but when the distance scale line also has one centimetre, must use glue head dropper constant volume instead.Because the wash bottle flow is big, the ordinary test personnel are difficult to the dynamics of control extrusion bottle, allow distilled water become to splash into volumetric flask, easily distilled water are added, and make liquid level surpass graduation mark, and it is on the low side that solution concentration is joined by institute, causes test error; Glue head dropper then because the volume of rubber cap is little, control well by the dynamics that squeezes, and can allow water become to drip drippage easily, but when using glue head dropper instead, need seek a clean beaker earlier and pour distilled water into, draw with dropper then, waste valuable test period, reduced test efficiency.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and has the droplet device, can save test period, improves the chemical test droplet wash bottle of test efficiency.
In order to reach above purpose, the technical scheme that the utility model adopted is: the droplet wash bottle of this chemical test, form by plastics narrow-mouthed bottle body and bottle cap, bottle cap covers on the mouth of plastics narrow-mouthed bottle body, it is characterized in that being provided with reservoir on the top of bottle cap, reservoir is connected with faucet on the bottle cap upper portion side wall, fix suction hose in the bottom of bottle cap, suction hose is connected with reservoir, bottle cap middle part at suction hose place suitable for reading is provided with control valve, is provided with the flexible arc wall on the upper wall of bottle cap.
The utility model is also implemented by following measure: the upper side wall of described plastics narrow-mouthed bottle body is provided with breather cheek valve.
The beneficial effects of the utility model are: owing to increased flexible arc wall and control valve on bottle cap, behind closed control valve, can a small amount of distilled water of access in the reservoir, by pushing the flexible arc wall on the bottle cap, control distilled water becomes drops to flow out from faucet, has realized the droplet function; Because liquid is stored in the plastics narrow-mouthed bottle body, has increased the storage liquid measure, liquid is the suction reservoir at any time, so, saved valuable test period, improved test efficiency.The utility model is simple in structure, easy to use, can carry out droplet in the experiment, has saved test period, has improved test efficiency, has reduced the working strength of testing crew.
Description of drawings
Fig. 1, be structure cross-sectional schematic of the present utility model.
The specific embodiment
Make the utility model with reference to accompanying drawing 1. the droplet wash bottle of this chemical test, form by plastics narrow-mouthed bottle body 1 and bottle cap 2, bottle cap 2 covers on the mouth of plastics narrow-mouthed bottle body 1, it is characterized in that being provided with reservoir 7 on the top of bottle cap 2, reservoir 7 is connected with faucet 6 on bottle cap 2 upper portion side wall, fix suction hose 3 in the bottom of bottle cap 2, suction hose 3 is connected with reservoir 7, bottle cap 2 middle parts at suction hose 3 places suitable for reading are provided with control valve 5, by control valve 5, can control the logical of suction hose 3 interior current, disconnected, on the upper wall of bottle cap 2, be provided with flexible arc wall 8, by pushing flexible arc wall 8, the distilled water that can easily control in the reservoir 7 becomes to ooze.
The upper side wall of described plastics narrow-mouthed bottle body 1 is provided with breather cheek valve 4, and when plastics narrow-mouthed bottle body 1 is in when pinching flat state, the outer air of bottle is restored to the original state plastics narrow-mouthed bottle body 1, convenient use by in breather cheek valve 4 unidirectional the inflow bottles.
Before doing the test of liquid constant volume, will fill distilled water in the bottle, it is standby to tighten bottle cap 2.During test, solution is transferred to volumetric flask after, open control valve 5, pinch compression molding material narrow-mouthed bottle body 1, allow the distilled water in this wash bottle become the current shape to add volumetric flask, until liquid level before one centimetre of graduation mark; At this moment, light kneading model material narrow-mouthed bottle body 1, when filling with water in the reservoir 7, closed control valve 5, plastics narrow-mouthed bottle body 1 outer air passes through breather cheek valve 4, flow in the bottle, the plastics narrow-mouthed bottle is restored to the original state, push flexible arc wall 8, allow reservoir 5 interior distilled water become to splash into volumetric flask, equal with graduation mark until the liquid level bottom, test is finished.
Claims (2)
1. chemical test droplet wash bottle, form by plastics narrow-mouthed bottle body (1) and bottle cap (2), bottle cap (2) covers on the mouth of plastics narrow-mouthed bottle body (1), it is characterized in that being provided with reservoir (7) on the top of bottle cap (2), reservoir (7) is connected with faucet (6) on bottle cap (2) upper portion side wall, the fixing suction hose (3) of going up in the bottom of bottle cap (2), suction hose (3) is connected with reservoir (7), bottle cap (2) middle part at suction hose (3) place suitable for reading is provided with control valve (5), is provided with flexible arc wall (8) on the upper wall of bottle cap (2).
