Above-mentioned the deficiencies in the prior art part is: once needs pulverizing is moist paper, paper is suitable for conduction through moisture, shredder is thought by mistake and be that human body has been encountered touch sensible bar or the coat of metal, cause shredder cisco unity malfunction, brought inconvenience to user.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of shredder that is suitable for the band touch protection of processing moist paper.
In order to solve the problems of the technologies described above, the invention provides the shredder that a kind of band that is suitable for processing moist paper touches protection, it comprises: microcontroller, be connected with this microcontroller whether there is the tactile paper sensor circuit of paper, the touch detection circuit for detection of human body touch signal and duration being connected with this microcontroller for the paper feed port for detection of shredder of controlling the on-off circuit of motor power break-make, be connected with this microcontroller; Described motor is connected with paper shredder transmission.
The band that is suitable for processing moist paper as another kind touches the shredder of protection, and it comprises: microcontroller, be connected with this microcontroller for the paper feed port for detection of shredder of controlling the on-off circuit of motor power break-make, be connected with this microcontroller whether exist paper tactile paper sensor circuit, be connected with this microcontroller be connected for detection of the touch detection circuit of human body touch signal, with this microcontroller be suitable for automatically reset pressure shredded paper button; Described motor is connected with paper shredder transmission.
Technique scheme of the present invention has the following advantages compared to existing technology: the method that the shredder of (1) band touch of the present invention protection is processed moist paper is suitable for comminution of moist paper; in the process of comminution of moist paper; the hand-held moist paper of user is also sent into paper in the paper feed port of shredder; and moist paper is suitable for conduction; it is that human body has been encountered touch sensible bar or the coat of metal that shredder is thought by mistake; as long as but make hand-held moist paper and exceed Preset Time time of contact with touch sensible bar or the coat of metal, can make shredder start shredded paper work.Thereby the shredder that makes band touch protection can be processed moist paper.(2) as another kind of scheme of the present invention, adopt one to be suitable for automatically reset pressure shredded paper button, exceed preset value as long as press the duration of this button, just can start the shredded paper program of forcing, no matter now whether touch detection circuit records human body touch signal, as long as paper is sent into the paper feed port while having paper in paper feed port (touch paper sensor circuit record) of shredder, all starter motor is carried out to shredded paper.The present invention adopts and is suitable for automatically reset pressure shredded paper button, but not conventional push button, mainly for guaranteeing to use safety, prevents from causing security incident because of maloperation.
Brief description of the drawings
For content of the present invention is more likely to be clearly understood, below the specific embodiment by reference to the accompanying drawings of basis, the present invention is further detailed explanation, wherein
Fig. 1 is the circuit block diagram that the band in embodiment 1 touches the shredder of protection;
Fig. 2 is the circuit block diagram that the band in embodiment 2 touches the shredder of protection.
Detailed description of the invention
Embodiment 1
See Fig. 1, the band in processing moist paper of the present embodiment touches the shredder of protection, and it comprises: microcontroller 2, the touch detection circuit 3 for detection of human body touch signal and duration that whether has the tactile paper sensor circuit 8 of paper, is connected with this microcontroller 2 for the paper feed port for detection of shredder of controlling the on-off circuit 4 of motor 1 on/off, be connected with this microcontroller 2 being connected with this microcontroller 2; Described motor 1 is connected with paper shredder transmission.
