Abstract
The utility model discloses a sand filter unit for children to play sand, which comprises a rack, wherein at least two layers of screens are arranged on the rack, and the meshes of the screens sequentially become thinner from the upper layer to the lower layer. Chutes are arranged on the rack, and the screens can slide in the chutes. Each screen has three layers which are respectively a first layer of screen, a second layer of screen and a third layer of screen from up to down; a container is arranged at the bottom of the rack; a hopper is arranged at the top part of the rack; and the rack is a frame which is produced by organic glass. Sand with different thickness is filled from the top part of the unit, and flows layer by layer through the screens which have the meshes that sequentially become thinner from the upper layer to the lower layer, accordingly, the process that the sand becomes thinner layer by layer is observed, under the separation condition that the sand has different thickness, the fundamental principles of sand filtration and object filtration are learnt, so children learn knowledge during the interaction use with tools and materials, and interest in actively investigating scientific secrets is improved during the play.
Description
Technical field
The utility model relates to toy for children, specifically is the device that a kind of children play husky usefulness.
Background technology
" play husky " activity is the ludic activity that each children very likes, and also is a kind of activity of developing creativity, it have start with beat one's brains combine, social science knowledge combines with natural science knowledge, science and the artistic characteristics that combine.Commonplace object for appreciation sand all is to utilize mould of plastics to make certain moulding in sand mostly at present; It is comparatively single to play husky mode; In playing husky activity, experience in order to bring the more Science Explorations of children; Let children can be intuitively in object for appreciation study separate the sand etc. of different thicknesses, this problem does not have comparatively ideal solution so far.
Summary of the invention
The purpose of the utility model provides a kind of children that can in object for appreciation, learn the sand work principle of filter and plays sand and use device.
The technical scheme that the utility model adopted is:
A kind of children play the sand filter of husky usefulness, comprise shelf, and shelf is provided with two-layer at least screen cloth, and the mesh of screen cloth from the upper strata toward lower floor successively from the coarse to fine.
Shelf is provided with chute, and said screen cloth can slide in chute.
The number of plies of screen cloth is three layers, is followed successively by ground floor screen cloth, second layer screen cloth, the 3rd layer of screen cloth from top to bottom.
The bottom of shelf is provided with container.
The top of shelf is provided with funnel.
Shelf is the framework that lucite is made.
Beneficial effect: the utility model can pour into the sand of different thicknesses from the top funnel of device; Through mesh from the upper strata toward lower floor's from the coarse to fine screen cloth successively; Make sand from level to level toward dirty; Thereby observe the process that sand successively attenuates, make children observe the separation case of different thicknesses sand intuitively, experience the flowability of sand.Can also twitch screen cloth gently, screen cloth is slided in chute, impel sand to flow.Through the separation case of different thicknesses sand, the study sand filters and then is the basic principle that object filters, make children with the mutual use of instrument, material in, learnt knowledge, in object for appreciation, improved the profound interest of the science of trying to explore.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-funnel, 2-ground floor screen cloth, 3-second layer screen cloth, 4-the three layer of screen cloth, 5-container, 6-shelf, 7-chute.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
A kind of children play the sand filter of husky usefulness, comprise shelf 6, and shelf 6 is provided with two-layer at least screen cloth, and the mesh of screen cloth from the upper strata toward lower floor successively from the coarse to fine.
Shelf 6 is provided with chute 7, and said screen cloth can slide in chute 7.
The number of plies of screen cloth is three layers, is followed successively by ground floor screen cloth 2, second layer screen cloth 3, the 3rd layer of screen cloth 4 from top to bottom.
The bottom of shelf 6 is provided with container 5.
The top of shelf 6 is provided with funnel 1.
The framework that shelf 6 is made for lucite.
With reference to Fig. 1, the utility model is the shelf 6 of a lucite, is three layers of drawing and pulling type screen cloth between wherein, the mesh of screen cloth from the upper strata successively from the coarse to fine toward lower floor, top and bottom are respectively rectangular lucite funnel 1 and container 5.Three layers of screen cloth is followed successively by ground floor screen cloth 2, second layer screen cloth 3, the 3rd layer of screen cloth 4 from top to bottom and can in chute 7, slides, and can unload and load onto, and dismounting is more flexible, is convenient to the cleaning of screen cloth.
The shape of the funnel 1 that the top is provided with and the container 5 of bottom can be designed to other moulding as required.
From the top funnel 1 of device, pour into the sand of different thicknesses; Through mesh from the upper strata toward lower floor's from the coarse to fine screen cloth successively; Make sand from level to level toward dirty; Thereby observe the process that sand successively attenuates, make children observe the separation case of different thicknesses sand intuitively, experience the flowability of sand.Can also twitch screen cloth gently, screen cloth is slided in chute, impel sand to flow.Through the separation case of different thicknesses sand, the study sand filters and then is the basic principle that object filters, make children with the mutual use of instrument, material in, learnt knowledge, in object for appreciation, improved the profound interest of the science of trying to explore.
