Abstract

The utility model relates to a tooth brushing timing device. The upper and the lower two cavities are arranged in the transparent casing of the tooth brushing timing device, the surface of the cavity is in a curved shape, a communication hole whose diameter is gradually reduced is arranged between the two cavities, and glass sand which can fill the partial space of a cavity is filled into the two cavities; the casing can have the structure of single-layer or double-layer, the transparent liquid can be filled in the space between the inner layer and the outer layer, and the small object in the form of suspension or semi-suspension is placed in the transparent liquid. The tooth brushing timing device is turned over from top to bottom, the glass sand which is gathered in the upper cavity can flow into the lower cavity, and the time taken by the flowage of all of glass sand from the upper cavity to the lower cavity is three minutes which just conforms to the scientific time length for tooth brushing. When the tooth brushing is about to be done, the tooth brushing timing device is turned over firstly and is placed in the right place; until all of glass sand in the upper cavity flows into the lower cavity, the tooth brushing can be stopped. Direct-viewing, convenience and strong interest can be obtained by using the utility model, the tooth brushing timing device is suitable for various people, and in particular, the tooth brushing timing device is suitable for the children.

Description

The timer of brushing teeth

Technical field

The utility model relates to a kind of timer of brushing teeth that is mainly used in the control brushing time.

Background technology

According to the modern scientific research achievement, best number of times of brushing teeth and time be brush teeth every day three times, brushed teeth in three minutes after meal at every turn, brushed teeth three minutes at every turn.Control brushing time voluntarily for controlling brushing time, particularly children, need a timer that meets the brushing time requirement, timing tools such as existing clock and watch are inconvenient owing to using, and shortage is interesting, are difficult to particularly children's acceptance by people.

The utility model content

The purpose of this utility model is to remedy the deficiencies in the prior art, and particularly children provide that a kind of interest is strong, good looking appearance, timing is directly perceived, easy to use and meet the timer of brushing teeth of science brushing time for people.

The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of timer of brushing teeth, comprise transparent shell, the profile of described housing is cylindricality, in establish up and down two cavity, described cavity surface is the curved surface shape, be provided with the intercommunicating pore of undergauge between two cavitys, described intercommunicating pore surface and described cavity surface smooth connection up and down, described two cavitys that are interconnected are built-in with the sand grains that can be full of a cavity segment space.

Sand grains in the utility model can flow to another cavity by a cavity by intercommunicating pore, through behind the certain hour, glass sand will all flow in the following cavity, timer is turned upside down, sand grains promptly flows to cavity down by the upper plenum after putting upside down, the time that all flows to down cavity is certain, the amount of change sand grains or the aperture of intercommunicating pore just can change sand grains and flow to the required time of another cavity by a cavity, this time span is set at three minutes, be that sand grains amount in the timer cavity is chosen to be the amount that flows to another cavity in three minutes from a cavity, so just can be used to the timing of brushing teeth.

Put well after earlier this timer being turned upside down before brushing teeth, promptly begin after putting well to brush teeth, when all flowing to down cavity, sand grains stops to brush teeth, Kong Zhi brushing time is three minutes just like this, therefore control is got up very intuitively and convenient, does not need to resemble to use and checks and zero computing time and termination time the ordinary clock timing; This timing mode itself is exactly a kind of amusement simultaneously, can attract children initiatively to use, and forms the good custom of regularly brushing teeth, and when particularly adopting various stained glass sand to do sand grains, more can strengthen its attractive in appearance and enjoyment; The cylindrical design of its outside surface in addition not only helps attractive in appearancely, and has made things convenient for and places and carry.

Description of drawings

Accompanying drawing is a perspective structure synoptic diagram of the present utility model.

Embodiment

Referring to accompanying drawing, the timer of brushing teeth that the utility model provides comprises transparent shell 1, the profile of described housing is cylindricality, in establish up and down two relative cavitys 2,3, described cavity surface is the curved surface shape, is provided with the intercommunicating pore 4 of undergauge between two cavitys, described intercommunicating pore surface and described two cavity surface smooth connections up and down, described two cavitys that are interconnected are built-in with the sand grains 5 of the segment space that can be full of a cavity, and the amount of described sand grains is the amount that flows to another cavity in three minutes from a cavity.

Described sand grains 5 can adopt colourless or stained glass sand, and its particle diameter can be about the 80-120 order, for example 80 orders, 100 orders or 120 orders, such sand grains is not only attractive in appearance interesting, but also the smooth and easy and timing that helps flowing accurately.

The quality of described glass sand can be the 1-10 gram, and for example 1 gram, 4 grams, 4.2 grams, 8 restrain or 10 grams, and the timer of making like this is small and exquisite, uses convenient, also attractive in appearance more interesting.

The surface of described each cavity 2,3 and through hole 4 can be rotationally symmetrical surf, and promptly cross-sectional edge is all rounded arbitrarily.

/ 5th, 1/10th, 1/15th or a thirtieth of a diameter that the described intercommunicating pore 4 minimum diameters of locating can be described cavity 2,3 maximums usually, or the arbitrary proportion between 1/5th to a thirtieth.

The outside surface cylindricality of described housing 1 can adopt cylinder usually, and perhaps multi-edge column-shapeds such as triangular prism, quadrangular, pentagonal prism, six prisms, eight prisms can adopt cylindrical or regular prism shape usually.

Described housing 1 can be a single or multiple lift, and is for example double-deck.

When described housing 1 is bilayer, can leave the space between two-layer, and be provided with a plurality of junctions, so that diversified moulding is fixed and produced to its internal layer, described outer 1 outside surface is the outside surface of timer, and the cavity up and down of described internal layer is the cavity up and down of timer.

Can be equipped with the transparency liquid that is full of its segment space or whole spaces in the space between the described two-layer housing, some colored suspensions or half wisp that suspends can also be set in the described transparency liquid, after timer spun upside down, described transparency liquid produces and flows, wisp in the liquid also moves, and can increase more enjoyment like this.

Described skin and internal layer can adopt mode such as bonding to link together, and also can directly be made of one.

For explaining conveniently, so-called cavity surface is meant the inside surface of the shell that forms this cavity, the i.e. boundary surface of cavity.
