Abstract

The utility model discloses a kind of teaching position water tank experiment external member, the external member includes tank, the water tank being placed in above tank and control circuit;Water pump is provided with the tank, metal bar is provided with water tank, metal bar is vertically placed in water tank, separately has water pipe one end to go deep into water tank, and the other end gos deep into being connected in tank and with water pump one end, and the other end of water pump and the upper end of metal bar are connected with control circuit respectively;The tank and water tank are made up of two various sizes of transparent plastic food box.The utility model imitates high-rise water tank and user's tank respectively using the transparent plastic food box of thinner and taller and more roomy two different shape size, experiment equipment volume is set to diminish, material price technological requirement reduces, substantially reduce price and volume, the grouping experiment of student is possibly realized, and this external member can form siphon, experiment can be made to go round and begin again, carry out always, allow student constantly to view and emulate, learn and know from experience principle therein, deepened the impression of student significantly.

Description

Teaching position water tank external member
Technical field
It the utility model is related to teaching equipment technical field, more particularly to a kind of teaching position water tank external member.
Background technology
The control of cistern water level is one of related electron controls technology case in life, in the thing in secondary school education stage Manage, the cistern water level content of courses is directed in more subjects such as science and general technology.General cistern water level teaching aid should be examined Consider the appearance for storing water receptacle that the height of water level makes aquatic products unboiled water position flow downward after water flows downward again as user pond Product, it is also necessary to use transparent material.Therefore, not only volume is big for general such teaching aid, also with clear perspex material system Make, teaching aid cost is more expensive, can not realize the grouping experiment of student, and glass container quality is heavy, frangible, can also be produced in teaching Some safety problems.
Utility model content
Purpose of utility model:To overcome the shortcomings of the existing technology, the utility model purport is in providing, a kind of cost is cheap, conveniently removes The teaching position water tank external member that fortune and safety coefficient are done.
Technical scheme:In order to solve the above technical problems, the utility model uses a kind of teaching position water tank experiment external member, Including tank, the water tank being placed in above tank and control circuit;Water pump is provided with the tank, metal is provided with water tank Rod, metal bar are vertically placed in water tank, separately have water pipe one end to go deep into water tank, and the other end gos deep into connecting in tank and with water pump one end Connect, the other end of water pump and the upper end of metal bar are connected with control circuit respectively;The tank and water tank are by two different sizes Transparent plastic food box be made.
Preferably, the tank volume is more than water tank.
Preferably, the tank is made of lateral cuboid shape transparent plastic food box, and its shape is more roomy.
Preferably, the water tank is made of vertical rectangular-shape transparent plastic food box, and its shape is thinner and taller.
Preferably, the metal bar is iron staff.
Beneficial effect:The utility model uses the transparent plastic food box of thinner and taller and more roomy two different shape size High-rise water tank and user's tank are imitated respectively, experiment equipment volume is diminished, and material price technological requirement reduces, and makes price and body Product is substantially reduced, and the grouping experiment of student is possibly realized, and this external member can form siphon, experiment can be made to go round and begin again, always Carry out, allow student constantly to view and emulate, learn and know from experience principle therein, deepened the impression of student significantly, greatly improved The learning efficiency of student.And plastic body adds much than the ontological security coefficient of original glass, weight is also light very It is more, it is convenient to carry.
Brief description of the drawings
Fig. 1 is the utility model structure diagram;
Fig. 2 is the utility model top view, and 7 be electric wire in figure.
Embodiment
In order to more fully understand the utility model, content of the present utility model is furtherd elucidate with reference to embodiment, but Content of the present utility model is not limited solely to the following examples.
A kind of teaching position water tank experiment external member, including tank 1, the water tank 2 and control circuit that are placed in the top of tank 1 3;Water pump 4 is provided with tank 1, metal bar 5 is provided with water tank, metal bar 5 is iron staff, and metal bar 5 is vertically placed in water tank 2, Separately there is the one end of water pipe 6 to go deep into water tank 2, the other end gos deep into being connected in tank 1 and with the one end of water pump 4, the other end and the gold of water pump 4 The upper end of category rod 5 is connected with control circuit 3 respectively.
Tank 1 is made of large volume of lateral cuboid transparent plastic food box, and its shape is more roomy, and water tank 2 uses The vertical rectangular-shape transparent plastic box of smaller size smaller is made, and its shape is thinner and taller.
During experiment, water is injected in water tank first, after water level did not had hose nozzle, because water tank and tank have height Difference, therefore siphonic effect can be produced, water pipe imports the water in water tank in tank.When needing the water in tank importing water again When in case, the water in tank is evacuated in water tank by open control circuit, water pump, is so gone round and begun again, and experiment can repeat always Carry out, deepen the teaching impression to students.
It the above is only preferred embodiment of the present utility model, it should be pointed out that:For the ordinary skill people of the art For member, on the premise of the utility model principle is not departed from, each facility locations can also be adjusted, these adjustment also should It is considered as the scope of protection of the utility model.
