Abstract
The utility model provides a piston-type water pump experimental instrument and relates to an experimental device. The piston-type water pump experimental instrument includes a plastic bottle provided with an upper cover. A conduit is installed in the upper cover of the plastic bottom. A water inlet in one end of the conduit is inserted into the plastic bottom. The other end of the conduit is connected with an injector. The upper cover of the plastic bottom is provided with a ventilating hole. The plastic bottle contains water. The piston-type water pump experimental instrument provided by the utility model is simple in structure and easy to manufacture and operate. Experimental phenomenon can be shown obviously and directly. Manufacturing raw material is easy to get and low in cost. Physical principles can be demonstrated clearly and understandable. The piston-type water pump experimental instrument can be used as a teaching instrument and also can be used as a small extracurricular experimental instrument for students.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to a kind of piston type water pumper experiment instrument.
Background technology
The piston type water pumper is also named and draws the formula water pumper, and principle is to utilize the movement of piston to discharge air, under the atmospheric effect in the external world, constantly draws water.
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 piston type water pumper 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 piston type water pumper experiment instrument, it is characterized in that: comprise that one has the plastic bottle of loam cake, covering of described plastic bottle conduit is installed, the water inlet of conduit one end is inserted in the plastic bottle, the conduit other end connects a syringe, cover on the plastic bottle and be provided with air hole, in the described plastic bottle water is housed.
The water inlet of described conduit is located at below the interior surface level of plastic bottle.
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 piston type water pumper experiment instrument as shown in Figure 1, comprise that one has the plastic bottle 1 of loam cake 2, loam cake 2 at plastic bottle 1 is equipped with conduit 3, the water inlet 6 of conduit 3 one ends is inserted in the plastic bottle 1, conduit 3 other ends connect a syringe 4, the loam cake 2 of plastic bottle 1 is provided with air hole 5, in the plastic bottle 1 water is housed.The water inlet 6 of conduit 3 is located at below the plastic bottle 1 interior surface level.
Pin the air hole that covers on the plastic bottle with hand, outwards spur syringe piston, syringe can not inhaled the water in the plastic bottle, unclamp finger after, under the atmospheric effect in the external world, syringe is the water in the sucking-off plastic bottle easily just.
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.
