Abstract
The utility model relates to an experiment apparatus and concretely relates to a siphon experiment instrument. The siphon experiment instrument comprises a plastic bottle having an upper cover, the upper cover of the plastic bottle is provided with a U-shaped tube, a tube orifice at one side of the U-shaped tube is inserted into the plastic bottle, the tube body at the other side of the U-shaped tube is provided with an annular tube, and the upper cover of the plastic bottle is provided with a vent. The siphon experiment instrument has the advantages of simple structure, easy making, easy operation, obvious and visual experiment phenomenon, and easy obtaining and low costs of making raw materials. The physical principle is intelligibly and understandably displayed by the siphon experiment instrument, so the siphon experiment instrument can be used as a teaching apparatus, and can also be used as an extracurricular small experiment apparatus for students.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to a kind of siphon experiment instrument.
Background technology
Siphonage is a kind of physical phenomenon.Be that liquid intermolecular attraction and potential energy difference cause, namely utilize water column pressure poor, flow to lower again after making liter waterborne.Because the mouth of pipe water surface bears different atmospheric pressures, while water can by pressure big to flow to pressure little, the atmospheric pressure up to both sides equates that the water surface in the container becomes identical height, water will stop to flow.
At present, be used for most experimental provision complex structure of physics teaching, the scope of application is wideless.And almost the basic principle of physics study is not tested and the experimental provision of making on the market, causing rigidly connecting tactile physical students in middle and primary schools can't be clear understandable to basic physics knowledge, add some theoretical property concepts physically, if do not explained orally analysis, be difficult to allow those students of begining to learn understand, thereby make most students forfeiture learning interest.
The utility model content
Technical problem to be solved in the utility model is to provide obviously siphon experiment instrument intuitively of a kind of making simple in structure, easy, easy to operate, experimental phenomena.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of siphon experiment instrument, it is characterized in that: comprise that one has the plastic bottle of loam cake, covering of plastic bottle U-shaped pipe is installed, the mouth of pipe of U-shaped pipe one side is inserted in the plastic bottle, the body of U-shaped pipe opposite side is provided with sleeve pipe, covers on the plastic bottle to be provided with air hole.
The mouth of pipe of described U-shaped pipe one side be inserted in the plastic bottle and with plastic bottle distance from bottom 2-5cm.
Nozzle position after described sleeve pipe stretches is lower than at the bottom of the plastic bottle bottle.
In the described plastic bottle water is housed.
The beneficial effects of the utility model are: the utility model making simple in structure, easy, easy to operate, experimental phenomena is obviously directly perceived, makes that raw material is easy to get, cost is low.Clear understandable with physical principle demonstration can be used as instruments used for education and uses, and also can be used as the extracurricular little experimental apparatus of student.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of siphon experiment instrument as shown in Figure 1, comprise that one has the plastic bottle 1 of loam cake, covering of plastic bottle 1 U-shaped pipe 2 is installed, the mouth of pipe of U-shaped pipe 2 one sides is inserted in the plastic bottle 1, the body of U-shaped pipe 2 opposite sides is provided with sleeve pipe 4, covers on the plastic bottle 1 to be provided with air hole 3.The mouth of pipe of U-shaped pipe 2 one sides be inserted in the plastic bottle 1 and with plastic bottle 1 distance from bottom 2-5cm.The mouth of pipe 5 positions after sleeve pipe 4 stretches are lower than at the bottom of 1 bottle of the plastic bottle.In the plastic bottle 1 water is housed.
The mouth of pipe of sleeve pipe is water delivering orifice, water under water delivering orifice is inhaled, water in the plastic bottle will nature in plastic bottle, flow out, the air hole that press...withes one's finger, plastics water in bottle will stop to flow out, after unclamping finger, water can continue outside outflow again, reentrant bushing length, and the water speed of outflow is slack-off, elongate sleeve; The water speed that flows out accelerates.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. siphon experiment instrument, it is characterized in that: comprise that one has the plastic bottle of loam cake, covering of described plastic bottle U-shaped pipe is installed, the mouth of pipe of U-shaped pipe one side is inserted in the plastic bottle, the body of U-shaped pipe opposite side is provided with sleeve pipe, covers on the plastic bottle to be provided with air hole.
2. a kind of siphon experiment instrument according to claim 1 is characterized in that: the mouth of pipe of described U-shaped pipe one side be inserted in the plastic bottle and with plastic bottle distance from bottom 2-5cm.
