Abstract

A waste destruction device for sharps, needles and solid waste preferably includes a material intake member, a destruction device and a storage member. The material intake member includes an intake housing and an intake cover. The intake cover pivots from an open to a closed orientation to receive objects to be shredded. At least one microprocessor board is used to control devices of the waste destruction device. The waste destruction device preferably includes a cutter housing, a first cutter member, a second cutter member, a cutter motor and a cutter intake housing. The waste destruction device preferably contains disinfection devices for disinfecting thereof. The storage member preferably includes a storage housing, a container drawer and a waste container. The container drawer is slidably received by the storage housing.

Claims (41)

1. A waste destruction device comprising:

a material intake member includes an intake housing and an intake cover, said intake cover pivots in said intake housing, wherein at least one object to be shredded is placed in said intake housing when said intake cover is in an open position, said intake cover is closed when the at least one object is shredded;

a destruction device includes a pair of counter-rotational cutting members, said destruction device is located below said material intake member;

a device for rotating said pair of counter-rotating cutting members;

a microprocessor board includes a timer system for setting a lock-out to prevent further shredding based on a number of shredding cycles until said cutting members are cleaned; and

a collection member is located below said destruction device, wherein said collection member receives the at least one object shredded by said destruction device.

2. The waste destruction device of claim 1 , further comprising:

a sensor for activating the opening and closing of said material intake member.

3. A waste destruction device comprising:

a material intake member includes an intake housing and an intake cover, said intake cover pivots in said intake housing, wherein at least one object to be shredded is placed in said intake housing when said intake cover is in an open position, said intake cover is closed when the at least one object is shredded;

a destruction device includes two counter-rotating cutting members, said destruction device is located below said material intake member;

a device for rotating said pair of counter-rotating cutting members;

a collection member is located below said destruction device, wherein said collection member receives at least one object placed in said material intake member and shredded by said destruction device;

a touch less sensor for closing said intake cover, said pair of counter-rotating cutting members will not rotate, until said intake cover is in a closed position, said touch less sensor activates a cover device to pivot said intake cover to said closed position for rotating said counter-rotating cutting members; and

a microcontroller board is capable of controlling said touchless system.

4. The waste destruction device of claim 2 wherein:

a drawer includes a base member and a front member, a bottom of said front member extends upward from a front edge of said base member, said base member is structured to receive said collection member, said collection member does not move laterally relative to said base member.

5. The waste destruction device of claim 1 wherein:

said microprocessor board includes a timer system for setting a desired date and duration for disinfecting an inside of said waste destruction device.

6. The waste destruction device of claim 3 wherein:

said microprocessor is capable of controlling a full container function for indicating that said collection member is full.

7. The waste destruction device of claim 3 wherein:

said microprocessor is capable of controlling a servicing indication for showing when said waste destruction device needs to be serviced or cleaned.

8. The waste destruction device of claim 3 wherein:

said touch less sensor activates said cover device to pivot said intake cover to an open position when said counter-rotating cutting members stop rotating.

9. A waste destruction device comprising:

a material intake member includes an intake housing and an intake cover, said intake cover pivots in said intake housing, wherein at least one object to be shredded is placed in said intake housing when said intake cover is in an open position, said intake cover is closed when the at least one object is shredded;

a destruction device includes two counter-rotating cutting members, said destruction device is located below said material intake member;

a device for rotating said pair of counter-rotating cutting members;

a collection member is located below said destruction device, wherein said collection member receives at least one object placed in said material intake member and shredded by said destruction device; and

a microprocessor includes a timer for dispensing a disinfection substance on to said counter-rotating cutter members after a set number of rotations thereof.

10. The waste destruction device of claim 9 wherein:

each one of said two counter-rotating cutting members are machined from a single piece of material.

11. The waste destruction device of claim 9 wherein:

said microprocessor is capable of controlling a full container function for indicating that said collection member is full.

12. The waste destruction device of claim 9 wherein:

said microprocessor is capable of controlling a servicing indication for showing when said waste destruction device needs to be serviced or cleaned.

13. The waste destruction device of claim 9 wherein:

said touch less sensor activates said cover device to pivot said intake cover to an open position when said counter-rotating cutting members stop rotating.

14. The waste destruction device of claim 9 wherein:

said microprocessor board includes a timer system for setting a desired date and duration for disinfecting an inside of said waste destruction device.
