Abstract
The invention relates to a paper shredder having touch protection, controlled by a microcontroller and used for treating humid paper sheets. According to the paper shredder, the following steps are included: (A) when a user holds the humid paper sheets and conveys the paper sheets into a paper inlet of the paper shredder, the microcontroller in the paper shredder measures a human body touch signal through a touch detection circuit when a touch induction strip on the paper shredder is touched, and a power supply of a motor is controlled by a switching circuit to keep a switched-off state; and (B) when the human body touch signal measured by the microcontroller through the touch detection circuit continuously exists for a period of time, the microcontroller controls the motor to be powered to work through the switching circuit until a paper touch induction circuit measures that the paper sheets do not exist in the paper inlet, and the power supply of the motor is controlled to be switched off after a touch protection function is recovered and the paper shredder is delayed for 1-3 seconds.
Description
Technical field
The present invention relates to the technical field of shredder, specifically the method for the moist paper of a kind of shredder process with touching protection.
Background technology
Existing medium-to-high grade shredder is all provided with touch defencive function at paper inlet, and it utilizes human body touch signal to judge that user points, whether long hair etc. is about to enter paper inlet, and point to prevent user, long hair etc. is brought in paper shredder.The such as circuit arrangement of a kind of shredder disclosed in Chinese patent literature CN201055797, as Fig. 1, it comprises motor 1, microcontroller 2, touch detection circuit 3, on-off circuit 4, liquid crystal display circuit 5, overheating protection circuit 6, paper jam testing circuit 7, tactile paper sensor circuit 8 and the full testing circuit 9 of paper for driving paper shredder; On-off circuit 4 is arranged in the current supply circuit at motor 1 place; Microcontroller 2 controls the power supply of motor 1 by on-off circuit 4; Touch detection circuit 3 comprises the touch sensible bar or the coat of metal and touch induction circuit of being located at shredder paper feed port place; Touch sensible bar or the coat of metal are connected with the human body touch signal input part of touch induction circuit; The touch signal input of the output termination microcontroller of touch induction circuit.Motor power-off can be made immediately when human body or animal touch the paper feed port of shredder, prevent it from coming to harm.
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 be that human body has encountered touch sensible bar or the coat of metal, cause shredder cisco unity malfunction, bring inconvenience to user.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for the moist paper of a kind of shredder process with touching protection.
In order to solve the problems of the technologies described above, the invention provides the method for the moist paper of a kind of shredder process with touching protection, it comprises the steps:
A, when the hand-held moist paper of user and by this paper send into shredder paper feed port process in, when touching the touch sensible bar on shredder, microcontroller in shredder records human body touch signal by touch detection circuit, and remains open state by the power supply of on-off circuit control motor;
B, after microcontroller records described human body touch signal sustainable existence a period of time by touch detection circuit; microcontroller controls motor by on-off circuit and obtains electric work; record in paper feed port when there is not paper until touch paper sensor circuit, recover to touch defencive function (that is: the power supply controlling motor when microcontroller records human body touch signal by touch detection circuit by on-off circuit remains open state) and the power supply controlling motor after 1-3 time delay second disconnects.
Alternatively, it comprises the steps:
A, when the hand-held moist paper of user and by this paper send into shredder paper feed port process in, when touching the touch sensible bar on shredder, microcontroller in shredder records human body touch signal by touch detection circuit, and controls to remain open state for the power supply of the motor driving paper shredder by on-off circuit;
B, when microcontroller record coupled be suitable for automatically reset pressure shredded paper button continued to press 5-15 second time, microcontroller controls motor by on-off circuit and obtains electric work, record in paper feed port when there is not paper until touch paper sensor circuit, the power supply controlling motor after 1-3 time delay second disconnects.
In described default time delay, if touch paper sensor circuit record in paper feed port the paper that exists and newly enter and described pressure shredded paper button is pressed time, microcontroller continues through on-off circuit and controls motor and obtain electric work so that continuously, batch comminution of moist paper.
Technique scheme of the present invention has the following advantages compared to existing technology: the method that (1) band of the present invention touches the moist paper of shredder process of protection is suitable for comminution of moist paper; in the process of comminution of moist paper; paper is also sent in the paper feed port of shredder by the hand-held moist paper of user; and moist paper is suitable for conduction; it is that human body has 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, shredder can be made to start shredded paper work.Thus make to be with the shredder touching protection can process moist paper.(2) as another kind of scheme of the present invention, one is adopted to be suitable for automatically reset pressure shredded paper button, as long as the duration of pressing this button exceedes preset value, just can start and force shredded paper program, no matter now whether touch detection circuit records human body touch signal, as long as paper to be sent into the paper feed port (when namely tactile paper sensor circuit records in paper feed port and there is paper) of shredder, all starter motor is carried out shredded paper.The present invention adopts and is suitable for automatically reset pressure shredded paper button, but not conventional push button, mainly for guaranteeing use safety, prevent from causing security incident because of maloperation.
Accompanying drawing explanation
In order to make content of the present invention be more likely to be clearly understood, below basis specific embodiment and by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is the circuit block diagram of the shredder that the band touch in embodiment 1 is protected;
Fig. 2 is the circuit block diagram of the shredder that the band touch in embodiment 2 is protected.
