Abstract

The utility model discloses a safety device of a paper crusher, which has emergent stopping functions. At least one induction component is arranged at the point adjacent to a paper feeding port of the paper crusher, and the induction component can be general foil or equivalent substitutes. The induction component is electrically connected with a traditional touch perception circuit and a motor drive circuit. When the induction component contacts a human body (a finger), the induction component sends a signal to order the motor drive circuit to switch off by the touch perception circuit to cause the motor to stop running so as to avoid hurting the human body (the finger) carried into the paper feeding port.

Description

Shredder safety device with emergency stop function

Technical field

The utility model relates to a kind of shredder, relate in particular to a kind of when finger touches paper inlet of paper shredder, can cut off the power supply automatically and promptly stop (emergency stop), be involved in the injured shredder safety device of paper inlet with emergency stop function to prevent to point.

Background technology

(the US CONSUMER PRODUCT SAFETYCOMMISSION of U.S. consumer products safety association; CPSC) issue No. 5127 file in May, 2004 at shredder safety alert news (Paper ShredderSafety Alert).Please refer to shown in Figure 1, this document reminds the family that has shredder must pay special attention to the safety of kinsfolk when the operation shredder, this association points out to have obtained 31 cases that cause the finger permanent disability because of the operation shredder accidentally between year December in January, 2000 to 2003, and most the wounded is 14 months to 2 years old big children (children), has particularly just begun to learn child (toddlers) on foot.Because the child in this stage enjoys a lot to imitate adult's action, when the adult is careless, play with shredder and damage.Even the adult can not guarantee that injury can not take place when supervising on the side, because shredder in broken paper process to pulling force that paper produced, suppose that the finger of holding paper fails in time to decontrol (let the papergo), then this pulling force may draw in (pull into) paper inlet of paper shredder (shredderopening) in the lump with finger and damages.

Therefore, CPSC warns the consumer to use shredder to must be noted that following item:

1. must not allow the child operate shredder separately.Even if there is the adult to guard on the side, the pulling force that also must realize shredder may draw in child's finger the danger of paper inlet of paper shredder in the lump;

2. shredder is placed on the child and is difficult for position contacting;

3. when not using shredder, pull up attaching plug;

4. avoid hand or finger are placed on the shredder;

5. be sure not to operate shredder during the loose clothing of wear, in order to avoid involved in paper inlet of paper shredder;

6. necktie or necklace etc. should keep a safe distance with paper inlet of paper shredder.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of shredder safety device with emergency stop function, and can cut off the power supply automatically when finger touches paper inlet of paper shredder promptly stops, to prevent that finger from being involved in paper inlet and avoiding injury.

Another technical problem to be solved in the utility model is to provide a kind of shredder safety device with emergency stop function, the paper of sending into shredder when unexpected vigilance is still withed a hook at the end necessity and when desiring promptly to stop shredded paper, can be made the automatic outage of shredder promptly stop with the finger touches inductive component.

Go up the danger of easily giving birth to for addressing the above problem and avoid the existing product operation, the utility model provides a kind of shredder safety device with emergency stop function, the place is provided with an inductive component at least in contiguous paper inlet of paper shredder, described inductive component can be general foil or equivalent substitution product, inductive component and tradition are touched perception circuit and motor drive circuit electric connection, when inductive component contact human body (finger) signal is cut off the power supply via touching perception circuits command motor drive circuit, it is injured to avoid human body (finger) to be involved in paper inlet that motor is shut down.

Traditional shredder does not almost have safety device, inevitably can people's finger be damaged, and the utility model is provided with the inductive component that is used to respond to the human body contact at contiguous paper inlet of paper shredder place, the signal that produces during inductive component utilization contact human body (finger) is via touching the outage of perception circuits command motor drive circuit, so that motor shuts down, it is injured to have avoided human body (finger) to be involved in paper inlet, therefore, the shredder safety device that provides of the utility model is that traditional shredder has been put forward safety guarantee.

The specific embodiment

Characteristics of the present utility model can be consulted the detailed description of illustrations and embodiment and obtained clearly to understand.

Please refer to the structure chart of Fig. 2 the utility model first embodiment, this paper inlet of paper shredder 1 is the semi-enclosed oblique paper of going in the icon, the inductive component made from foil 2 is arranged on paper inlet 1 leading edge locus in the present embodiment, described foil 2 is towards paper inlet 1 direction and be bent downwardly suitable angle formation kink 21, just in case finger when being involved in paper inlet 1, finally still can be touched described kink 21 and trigger induction to guarantee safety.Described foil 2 touches the perception circuit with tradition and shredder motor drive circuit (not shown) electrically connects; when making the contact of foil 2 finger sensing; signal is cut off the power supply via touching perception circuits command motor drive circuit; motor is shut down to avoid finger to be involved in paper inlet 1, reach the protection effect of avoiding false touch injured.

Please refer to the structure chart of Fig. 3 second embodiment, paper inlet of paper shredder described in the icon 1 is for open directly to going into paper, the inductive component made from foil 2a, 2b is separately positioned on 1 liang of side position of open paper inlet in the present embodiment, same described foil 2a, 2b is bent downwardly suitable angle towards paper inlet 1 and forms kink 21a, 21b, just in case finger when being involved in paper inlet 1, finally still can be touched described kink 21a, 21b and trigger induction to guarantee safety.Described foil 2a, 2b and tradition touch the perception circuit and shredder motor drive circuit (not shown) electrically connects; when making foil 2a, the contact of 2b finger sensing; signal is cut off the power supply via touching perception circuits command motor drive circuit; motor is shut down to avoid finger to be involved in paper inlet 1, reach the protection effect of avoiding false touch injured.

Utilize above-mentioned touch induction component to cause and touch the function that the outage of perception circuits command motor drive circuit shuts down motor, except avoid the finger involved in paper inlet injured, for promptly stopping as desiring in the shredded paper process, also can motor be shut down via touch induction component.
