Abstract
The utility model discloses a plastic washing bottle with an air inlet valve, which mainly comprises a plastic bottle, a bottle cap, a water guide pipe and an air inlet valve. The air inlet valve is installed on the bottle cap and comprises a valve body, a sealing gasket and a spring position limiting clamp. The air inlet valve can be closed or opened by squeezing and loosening the washing bottle during operation to restore the bottle body rapidly, so as to repeatedly discharge distilled water in a short pause time, thereby shortening wares rinsing time or distilled water filling time and improving work efficiency.
Description
Technical field
The utility model relates to a kind of laboratory paraphernalia, is meant that especially the laboratory is used for a kind of plastic squeeze bottle that has intake valve in experimental ware flushing, the filling of solution distilled water.
Background technology
In universities and colleges, enterprise, the scientific research institution laboratory of industries such as chemistry, chemical industry, biology, medicine, food, geology, metallurgy, environment, all to use the wash bottle that is used to wash experimental ware and solution preparation filling distilled water.At present generally usefulness be the wash bottle that plastics are made, this wash bottle just by plastic bottle, wash bottle head, water outlet chew, aqueduct combines.This wash bottle makes distilled water chew discharge through aqueduct, wash bottle head, water outlet by extrusion bottle in the middle of using, and experimental ware is washed the filling of distilled water when preparing with solution; Be expressed to a certain degree, wash bottle no longer during water outlet, need be unclamped bottle and make its elasticity of leaning on self that bottle is restored to the original state, and this moment, distilled water water suck-back returned in the bottle, air by water outlet chew, wash bottle head, aqueduct enter in the bottle; And then extrusion bottle is discharged distilled water.In this process, because water outlet is chewed the narrow and small and aqueduct of aperture and water in bottle air is entered the formation resistance, air enters and need overcome these resistances and just can enter in the bottle, the bottle ability resilient so need wait for a period of time, the filling of distilled water brings some inconvenience when giving the flushing of experimental ware in the experimental implementation and solution preparation, has prolonged the working time.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of plastic squeeze bottle that has intake valve is provided.This wash bottle can make air enter fast in the bottle in operation, and the plastic squeeze bottle bottle is restored to the original state fast, has shortened the operating time.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of plastic squeeze bottle that has intake valve comprises plastic bottle, bottle cap, aqueduct.On bottle cap, be provided with can make gas enter the bottle in intake valve.
Technical problem of the present utility model is also realized by following scheme: described intake valve is made up of columniform valve body, sealing gasket, the spacing card of spring.
Compared with prior art, the utility model has the advantages that: behind wash bottle bottle extrusion drainage, loosen bottle make air enter the bottle in process in, do not need to return in the bottle through the distilled water suck-back, air by water outlet chew, aqueduct enters into the process that waits as long in the bottle, but the unlatching by intake valve, air directly enters in the bottle by air admission hole fast, the wash bottle bottle is restored to the original state rapidly, and the time of filling distilled water has been improved operating efficiency when having shortened flushing experimental ware and solution preparation.
Description of drawings
Fig. 1 is for having intake valve plastic squeeze bottle schematic diagram
Fig. 2 is the intake valve structural representation
The specific embodiment
Be described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, 2, during use, at first aqueduct 2, intake valve 4 are snugly fitted on the plug 3 that has two holes, distilled water is poured in the plastic bottle 1, with the plug 3 that aqueduct 2, intake valve 4 are housed plastic bottle 1 bottleneck is tightly built again.When flushing experimental ware and solution preparation, with hand extruding plastic bottle 1 bottle, the interior distilled water of bottle rises by aqueduct 2 and discharges by delivery port; When hand loosened bottle, air was entered in the bottle by intake valve 4, and bottle restores fast.In the extrusion bottle drainage procedure, the rubber gasket 7 in the intake valve 4 moves upward under the effect of bottle inner air pressure and closely contacts the formation sealing with the air admission hole 6 of valve body 5 the first half, stops air to be discharged by air admission hole 6, and intake valve 4 is in closed condition; Meanwhile, the distilled water in the bottle is pressed into aqueduct 2 under the effect of bottle inner air pressure, discharged by delivery port.In unclamping flat bottle process, owing to produce the effect of negative pressure in the bottle, rubber seal 7 moves downward and drops on the stainless steel spring card 8, rubber gasket 7 breaks away from air admission hole 6, air enters in the bottle by the space of the latter half cavity in air admission hole on the intake valve 46 and the valve body 5, bottle restores to the original state fast, and this moment, intake valve 4 was in opening.Push, loosen the wash bottle bottle with hand so repeatedly, distilled water is discharged in the short intermittent time repeatedly.
Claims (6)
1. a plastic squeeze bottle that has intake valve comprises plastic bottle, bottle cap, aqueduct, it is characterized in that: on bottle cap, be provided with can make gas enter the bottle in intake valve.
