Description
Technical field
It the utility model is related to chalk holder, more particularly to a kind of intelligent chalk holder.
Background technology
Chalk holder is the box body for storing chalk, and in places such as school, training organizations using more, its material is mostly paper
Matter, and in order to improve the firmness of chalk holder, also have using plastics chalk holder, metal chalk holder etc., but regardless of chalk
Box, when teacher at school during find there is no chalk in chalk holder or during using complete chalk, it is necessary to take time to take chalk,
Cause the waste of class period.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of surplus that can detect chalk in chalk holder in real time,
The intelligent chalk holder supplemented in time so as to chalk.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of intelligent chalk holder, including box body
With the reception system being arranged in caretaker room, the bottom of described box body is fixedly installed gravity sensor and wireless transmission mould
Block, described gravity sensor electrically connect with described wireless sending module, described reception system include wireless receiving module,
Comparison module, display module and alarm module, described wireless receiving module, described display module, described alarm module
Electrically connected respectively with described comparison module, meanwhile, described alarm module, described display module respectively with it is described wireless
Receiving module electrically connects.
Further, calling module, described calling module and described wireless transmission mould are provided with described box body
Block electrically connects.
Compared with prior art, the utility model has the advantages that the intelligent chalk holder can detect and powder in display box body in real time
The surplus of pen, when the surplus of chalk in box body is less than setting value, alarm can be sent in time, reminds keeper to add in time
Chalk, ensure the normal use of chalk.
Brief description of the drawings
Fig. 1 is forward structure schematic diagram of the present utility model；
Fig. 2 is polycrystalline substance schematic diagram of the present utility model；
Fig. 3 is that circuit module of the present utility model connects block diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As illustrated, a kind of intelligent chalk holder, including box body 1 and the reception system being arranged in caretaker room, the bottom of box body 1
Portion is fixedly installed gravity sensor 2 and wireless sending module 3, and the side of box body 1 is provided with calling module 4, calling module 4,
