Abstract
The utility model discloses a plastic washing bottle for a laboratory. The plastic washing bottle for the laboratory comprises a plastic washing bottle body (1), a nozzle pipeline (3) is connected to a bottle cover (2) of the plastic washing bottle body (1), a one-way water outlet valve (4) is mounted on the nozzle pipeline (3), an air return pipe (5) is further mounted on the bottle cover (2), a lower pipe opening of the air return pipe (5) is located above the liquid level of the plastic washing bottle body (1), and a one-way air inlet valve (6) is mounted on the air return pipe (5). According to the plastic washing bottle for the laboratory, the air return pipe is arranged on the plastic washing bottle body, the one-way air inlet valve is arranged on the air return pipe, the one-way water outlet valve is arranged on the nozzle pipeline, so that under the action of the one-way valves, discharged water passes through the nozzle pipeline and returned air passes through the air return pipe. Therefore, the defect that liquid is polluted when air returns in an ordinary washing bottle is effectively avoided, and the problem that air passes through the liquid in a cavity and causes pollution when the air returns in the ordinary washing bottle is avoided.
Description
Technical field
The utility model relates to a kind of use for laboratory plastic squeeze bottle, belongs to the laboratory paraphernalia technical field.
Background technology
Plastic squeeze bottle is one of laboratory utensil commonly used, and red bottle cap and two types of white bottle caps are arranged.Injection pipe and the return-air duct of common plastics wash bottle unite two into one, like this after the external force pressurized jet goes out liquid, return-air is got back to the wash bottle cavity along injection pipe, because the straight tube in the wash bottle cavity reaches the bottom, so air can be brought into the liquid such as airborne dust and other impurity by the liquid in the wash bottle when return-air, liquid in the wash bottle is brought secondary pollution, and highly sophisticated device brings impurity to disturb to testing especially, affects the measuring result.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of resorption air and dust of can preventing that liquid in the bottle is caused the use for laboratory plastic squeeze bottle of secondary pollution, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: it comprises plastic squeeze bottle, bottle cap at plastic squeeze bottle is connected with nozzle pipe, at nozzle pipe the one-way water outlet valve door is installed, muffler is installed on bottle cap in addition, the lower nozzle of muffler is positioned at more than the liquid level of plastic squeeze bottle, at muffler Unidirectional air inlet valve is installed.
The lower end mouth of pipe of muffler flushes with the lower capping of bottle cap.
One-way water outlet valve door and Unidirectional air inlet valve are made of interior sleeve pipe and the ball of establishing round taper hole, and ball is in the round taper hole of sleeve pipe.
Offer a circle lateral jet hole at the jet hole place of nozzle pipe.
Compared with the prior art, the utility model arranges air inlet pipe at plastic squeeze bottle, and Unidirectional air inlet valve and one-way water outlet valve door are set respectively on air inlet pipe and nozzle pipe, like this, because the effect of check valve just can guarantee water outlet and walk nozzle pipe that return-air is walked air inlet pipe; Thereby the shortcoming of contaminated liquid when effectively avoiding common wash bottle return-air, the pollution that air causes through liquid in the cavity when preventing common wash bottle return-air.Owing to the liquid of air inlet route without wash bottle, can reduce like this air drag, realize quick return-air simultaneously, shorten the return-air stand-by period.Offer a circle lateral jet hole at the jet hole place of nozzle pipe, when washing in vitro material with wash bottle, just can conveniently develop being adsorbed on test tube tube wall material all around like this.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment 1, as shown in Figure 1, be connected with bottle cap 2 at plastic squeeze bottle 1, bottle cap 2 at plastic squeeze bottle 1 is connected with nozzle pipe 3 and return-air duct 5, at the bottom of the import of nozzle pipe 3 is positioned at bottle, offer a circle lateral jet hole at the jet hole place of nozzle pipe 3, the lower nozzle of muffler 5 is positioned at more than the liquid level of plastic squeeze bottle 1, the lower end mouth of pipe that is preferably designed for muffler 5 flushes with the lower capping of bottle cap 2, for preventing nozzle pipe 3 air inlets, at nozzle pipe 3 one-way water outlet valve door 4 is installed, for preventing muffler 5 water outlets, at muffler 5 Unidirectional air inlet valve 6 is installed.One-way water outlet valve door 4 and Unidirectional air inlet valve 6 are made of interior sleeve pipe 6 and the ball 8 of establishing round taper hole, and ball 8 is positioned at the round taper hole of sleeve pipe 7.
