Description
- The present invention relates to waste compression devices with a fee calculation function, and more particularly, to a processing device for shaking and compressing wastes and calculating the quantity of the wastes, and includes a casing having therein a storage cart for holding the waste, a vibration unit, and a compression unit, and more particularly, to a waste compression device with a fee calculation function, wherein the waste compression device comprises a casing having therein a control unit and a sensor of a compression unit for controlling the vibration unit, as well as an interface unit and a ticketing unit which are controlled by the control unit.
- Recyclable wastes include aluminum foil bags, iron cans, aluminum cans, and plastic bottles. A conventional method for recycling the waste involves sorting collected wastes into paper, metal, and plastics, and then compressing various wastes with a compressor to reduce the volume of the wastes and thereby facilitate the storage and delivery thereof.
- However, plenty of the wastes are liquid containers, such as bottles and cans; hence, residual liquid inside the containers is likely to leak into the surroundings. In particular, upon compression of the wastes, the residual liquid escapes from the containers to thereby end up in the surroundings completely and accumulate in the form of waste liquid. When exposed to air and sunshine for a long period of time, the waste liquid is likely to rot, ferment, and breed germs, mosquitoes, and flies to the detriment of environmental hygiene.
- To solve the above problems, a commercially available waste compressing and freezing locker with storing, freezing, and compressing functions is put forth according to the prior art. Bags of wastes are cast into the waste compressing and freezing locker and compressed therein. Inside the waste compressing and freezing locker, the wastes and waste liquid therein are frozen and prevented from causing environmental pollution.
- To encourage consumers to take the initiative in recycling wastes, some warehouse stores and convenience stores offer customers various coupons in exchange for recyclable wastes. The coupons are required for joining a points reward scheme or receiving a cash discount or a gift. However, the waste compressing and freezing locker determines the quantity of wastes therein by weighing the wastes. If the quantity of the wastes is assessed by the quantity of bottles and cans, the assessment result will be inaccurate.
- Furthermore, the prior art teaches counting the bottles and cans of wastes with a commercially available barcode scanning device. However, it is incapable of compressing and freezing wastes, not to mention that the barcode on the bottles and cans is susceptible to damage and is likely to be smeared, thereby compromising the accuracy of barcode scanning. Accordingly, it is imperative to overcome the aforesaid drawbacks of the prior art.
- The document TWM415760U discloses a waste compactor in accordance with the preamble of
claim 1. - It is an objective of the present invention to enhance the ease of operation in terms of compressing wastes and calculating the quantity of the wastes, by overcoming the drawbacks of the prior art - the quantity of the wastes is assessed by weighing the wastes and performing barcode scanning, thereby compromising the accuracy of calculating the quantity of the wastes.
- In order to achieve the above and other objectives, the present invention provides a waste compression device in accordance with
claim 1, with a fee calculation function, comprising a casing, the casing having a waste inlet and having therein: - a control unit;
- a compression unit positioned proximate to a top of the casing and electrically connected to the control unit;

FIG. 5 is a cross-sectional view of a use state ofFIG. 4 ; and -
FIG. 6 is a cross-sectional view of an additional embodiment related to the embodiment ofFIG. 1 . - Referring to
FIG. 1 , there is shown a perspective view of a preferred embodiment of the present invention. Referring toFIG. 1 ,FIG. 2 andFIG. 3 , according to the present invention, a waste compression device with a fee calculation function comprises acasing 1. Awaste inlet 11 is disposed on the outer wall of thecasing 1. Thecasing 1 has therein acontrol unit 21, acompression unit 22, astorage cart 23, aquantity sensor 24, astorage level sensor 25, afreezing unit 26, aninterface unit 27, aticketing unit 28, and avibration unit 43. Thecontrol unit 21 is a control circuit board or a chip. Thecompression unit 22 is positioned proximate to the top of thecasing 1 and electrically connected to thecontrol unit 21. Thecompression unit 22 has apress plate 221 capable of vertical reciprocating movement and anactuator 222 for actuating thepress plate 221. - The
storage cart 23 is disposed beneath and corresponds in position to thepress plate 221 of thecompression unit 22. Thestorage cart 23 has therein astorage chamber 231 opening upward. Thestorage chamber 231 is disposed beneath thepress plate 221 and is in communication with theinlet 11, such that arecyclable wastes 7, such as aluminum foil bags, iron cans, aluminum cans, and plastic bottles, can be cast into thecasing 1 through theinlet 11 so as to be contained in thestorage chamber 231 of thestorage cart 23. - The
vibration unit 43 is disposed at the bottom of thestorage cart 23 and electrically connected to thecontrol unit 21. Thevibration unit 43 comprises therein a vibrating motor. The bottom of thestorage cart 23 is in contact with thevibration unit 43 or rests on thevibration unit 43, such that thevibration unit 43 is capable of shaking thestorage cart 23 to thereby shake thewastes 7 inside thestorage cart 23. Therefore, thewastes 7 thus shaken sink and level off. - The
quantity sensor 24 is disposed on the inner wall of theinlet 11 and electrically connected to thecontrol unit 21. Thequantity sensor 24 comprises an emittingelement 241 and a receivingelement 242 which correspond in position to each other (as shown inFIG. 4 ). Asingle waste 7 passing through theinlet 11 and between the emittingelement 241 and the receivingelement 242 stops the receivingelement 242 from receiving a signal emitted from the emittingelement 241. As a result, thequantity sensor 24 senses a single blocking signal, calculates the quantity of thewastes 7, and sends a quantity signal to thecontrol unit 21. - The
storage level sensor 25 is disposed at the proximal side of arim 233 of thestorage chamber 231 of thestorage cart 23 and electrically connected to thecontrol unit 21. Thestorage level sensor 25 senses a level of thewastes 7 inside thestorage cart 23 and determines whether the level reaches a preset height. Thecontrol unit 21 instructs thevibration unit 43 to shake thestorage cart 23 as soon as thestorage level sensor 25 determines that the level of thewastes 7 inside the storage cart 2 reaches the preset height for the first time, and instructs thecompression unit 22 to drive thepress plate 221 to press thewastes 7 inside thestorage cart 23 as soon as thestorage level sensor 25 detects that the level of thewastes 7 inside thestorage cart 23 reaches the preset height for the second time. - In practice, the
storage level sensor 25 comprises therein a counter for counting the number of instances thestorage level sensor 25 detects that the level of thewastes 7 reaches the preset height. The counter resets to zero upon reaching the preset height for the second time, so as to restart the counting process. The preset height refers to a position below therim 233 and within thestorage chamber 231, as high as therim 233, or above therim 233. In this embodiment, the preset height refers to a position above therim 233 and near therim 233. - The
storage level sensor 25 comprises an emittingelement 251 and a receivingelement 252 which correspond in position to each other. Once thewastes 7 in thestorage chamber 231 accumulate enough to rise above therim 233, thewastes 7 located at therim 233 of thestorage chamber 231 stop the receivingelement 252 from receiving a signal emitted from the emittingelement 251, so as for thestorage level sensor 25 to detect that the level of thewastes 7 in thestorage cart 23 has reached the preset height and thereby send a level signal to thecontrol unit 21. The level signal enables the counter of thecontrol unit 21 to count the number of instances the level of thewastes 7 reaches the preset height, such that thecontrol unit 21 can determine the best time to instruct thevibration unit 43 to shake thestorage cart 23 and instruct thecompression unit 22 to press thewastes 7 inside the storage cart 23 (seeFIG. 5 ). - The freezing
unit 26 is disposed on the inner wall at the top of thecasing 1 and comprises a compressor, a condenser, and a fan. The freezingunit 26 has acool air outlet 261 in communication with the inside of thecasing 1, thestorage cart 23, and thecompression unit 22. Cool air supplied by the freezingunit 26 is delivered to the inside of thecasing 1 via thecool air outlet 261 in a manner that the cool air spreads downward to distribute across the inside of thecasing 1 uniformly, such that the cool air undergoes convection inside thecasing 1 and between thestorage cart 23 and thecompression unit 22. Therefore, there is uniform distribution of the temperature of the cool air at every corner in thecasing 1, such that thewastes 7 inside thestorage cart 23 are preserved at a low temperature. - The
interface unit 27 is exposed from the outer wall of thecasing 1, electrically connected to thecontrol unit 21, and adapted to receive the quantity signal and the level signal, so as to display the quantity and level of thewastes 7, such that a caretaker and a user can be informed of the quantity and level of thewastes 7 in real time. - Furthermore, the
interface unit 27 is controlled by the user to send an acknowledgment signal to thecontrol unit 21 and thereby instruct thecontrol unit 21 to generate a ticketing signal. Alternatively, thecontrol unit 21 can generate an instruction signal. Theinterface unit 27 receives the instruction signal and sends an operation instruction for guiding the user in operating appropriately. - In practice, the
interface unit 27 comprises avoice receiver 271 and aspeaker 272, and can also comprise adisplay 273 and a plurality ofbuttons 275. In practice, thedisplay 273 is a liquid crystal display or a touch panel. Theinterface unit 27 further comprises at least anindicator 274. Thespeaker 272, thedisplay 273, or theindicator 274 sends an operation instruction and displays the quantity and level of thewastes 7. Thevoice receiver 271, a touch panel, or thebuttons 275 receives an acknowledgment signal sent from the user by means of voice-based control or manual operation. - The
ticketing unit 28 is exposed from the outer wall of thecasing 1 and forms aticketing slot 281. Theticketing unit 28 is electrically connected to thecontrol unit 21, receives the ticketing signal, and dispenses to a user acoupon 6 required for joining a points reward scheme or receiving a cash discount or a gift. - In this embodiment, a
control box 12 is disposed on the outer wall of thecasing 1 and adapted to house thecontrol unit 21. Thevoice receiver 271, a sound aperture of thespeaker 272, thedisplay 273, thebuttons 275, and theindicator 274 of theinterface unit 27 as well as theticketing slot 281 of theticketing unit 28 are positioned on the surface of thecontrol box 12. - Therefore, the user casts the
recyclable wastes 7, which are packaged in bottles, cans, or aluminum foil bags, into thestorage chamber 231 of thestorage cart 23 through theinlet 11 one by one according to an operation instruction given by theinterface unit 27. - At this point in time, the
quantity sensor 24 detects thewastes 7 and calculates the quantity of thewastes 7, whereas thecontrol unit 21 receives the quantity signal from thequantity sensor 24, calculates the quantity of thewastes 7 cast into thestorage cart 23, and instructs theinterface unit 27 to inform the user of the quantity of thewastes 7 in real time. - After casting all the
available wastes 7 into thestorage cart 23, the user enters an acknowledgment signal into theinterface unit 27 by means of voice-based control or manual operation in accordance with an operation instruction given by theinterface unit 27. Upon receipt of the acknowledgment signal, thecontrol unit 21 stops calculating the quantity of thewastes 7 and sends the ticketing signal to theticketing unit 28 according to the calculated quantity of thewastes 7 to thereby instruct theticketing unit 28 to dispense thecoupons 6 continuously. - Meanwhile, the freezing
unit 26 delivers the cool air to the inside of thecasing 1 via thecool air outlet 261 and thereby preserves thewastes 7 in thestorage cart 23 at a low temperature, whereas thestorage level sensor 25 keeps sensing a level of thewastes 7 in thestorage cart 23 and determines whether the level has reached the preset height. - Once the
storage level sensor 25 detects that the level of thewastes 7 in thestorage cart 23 reaches the preset height for the first time, thecontrol unit 21 will instruct thevibration unit 43 to shake thestorage cart 23 briefly, such that thewastes 7 in thestorage cart 23 sink due to the shaking. As a result, thewastes 7 in thestorage chamber 231 level off, such that the level of thewastes 7 is lower than the preset height. Accordingly, the volume of thewastes 7 thus accumulated is reduced, and thestorage cart 23 can store more said wastes 7. - Once the
storage level sensor 25 detects that the level of thewastes 7 in thestorage cart 23 reaches the preset height for the second time, thecontrol unit 21 will instruct theactuator 222 of thecompression unit 22 to drive thepress plate 221 to move downward into thestorage chamber 231 and thereby cause thepress plate 221 to perform top-to-bottom compression of thewastes 7 in thestorage chamber 231, such that the level of thewastes 7 is lower than the preset height. Therefore, after being compressed by thepress plate 221 of thecompression unit 22, thewastes 7 in thestorage chamber 231 continue to be stored inside thestorage cart 23. - Therefore, the
recyclable wastes 7 packaged in bottles, cans, or aluminum foil bags are cast into thestorage cart 23 through theinlet 11. Once thestorage level sensor 25 detects that the level of thewastes 7 in thestorage cart 23 reaches the preset height, thestorage level sensor 25 will instruct thecompression unit 22 to drive thepress plate 221 to perform top-to-bottom compression of thewastes 7 in thestorage cart 23 to thereby reduce the volume of thewastes 7, especially the volume of the bulkyrecyclable wastes 7, such as PET bottles or cartons, thus increasing the storage capacity of thestorage cart 23 and deceasing the required number of instances thewastes 7 are collected. - The freezing
unit 26 delivers the cool air to every corner of the inside of thecasing 1. Therefore, there is uniform distribution of the temperature of the cool air inside thecasing 1. Therefore, water-containing wastes or leftovers, which are stored in thestorage cart 23, can be preserved at a low temperature, so as to prevent the wastes or leftovers from producing a foul odor, breeding vector mosquitoes, and causing environmental pollution. - By shaking the
storage cart 23 with thevibration unit 43, it is feasible to enable thewastes 7 in thestorage chamber 231 to level off and thereby enhance the efficiency of the storage of thewastes 7 therein with a view to reducing the volume of wastes and maintaining environmental hygiene. - In a variant embodiment, multiple said
inlets 11, multiple saidcompression units 22, multiple saidstorage carts 23, multiple saidquantity sensors 24, multiple saidstorage level sensors 25, and multiple saidvibration units 43 are provided and disposed inside single saidcasing 1. Therefore, the user can cast aluminum foil bags, iron cans, aluminum cans, and plastic bottles into thedifferent inlets interface unit 27. - A
gate 14 is disposed on one side of thecasing 1 and adapted to remove thewastes 7 from thestorage cart 23. Thegate 14 is shut with adoor panel 15. Once thestorage cart 23 is full, a janitor will take thestorage cart 23 out via thegate 14 and collect thecompressed wastes 7 in thestorage cart 23. - The
control unit 21 and anexternal computer 3 are connected to each other by wired connection or wireless connection for sending the quantity signal, the level signal, the acknowledgment signal, and the ticketing signal to thecomputer 3. Thecomputer 3 determines the best time for thecontrol unit 21 to instruct thecompression unit 22 to press thewastes 7, such that the caretaker can understand and manage the storage, refrigeration, and compression condition of thewastes 7 and thereby perform remote management. - To collect the waste liquid produced from the
wastes 7 inside thestorage cart 23, at least aleakage hole 232 is formed at the bottom of thestorage cart 23. Acollector 29 is disposed beneath theleakage hole 232 of thestorage cart 23 to receive, via theleakage hole 232, the waste liquid produced from thewastes 7 stored in thestorage cart 23 and compressed by thecompression unit 22. Adrainpipe 291 extending to the outside is disposed at one end of thecollector 29 and adapted to draw off the waste liquid from thecollector 29. - A
slope 234 that faces upward is formed at the bottom of thestorage chamber 231 for guiding the waste-derived waste liquid in flowing toward the bottom of thestorage chamber 231 and thereby flowing into theleakage hole 232. - A
battery recycling inlet 13 is formed on the outer wall of thecasing 1. Abattery recycling bin 41 in communication with thebattery recycling inlet 13 is disposed inside thecasing 1. Abattery quantity sensor 42 is disposed inside thebattery recycling inlet 13 and electrically connected to thecontrol unit 21. Thebattery quantity sensor 42 comprises an emittingelement 421 and a receivingelement 422 which correspond in position to each other. A single battery passing through thebattery recycling inlet 13 and between the emittingelement 421 and the receivingelement 422 stops the receivingelement 422 from receiving a signal sent from the emittingelement 421, thereby allowing thebattery quantity sensor 42 to sense a single blocking signal, calculate a battery quantity, and display the battery quantity with theinterface unit 27. - It is also feasible to provide an
inlet 11c for wastes, such as iron cans and aluminum cans, in the form of a single inlet (as shown inFIG. 6 ), and position amagnet 5 between theinlet 11c and astorage cart 23a intended for iron cans. Under an attractive magnetic force generated from themagnet 5, ferric wastes, such as iron cans, fall into thestorage cart 23a. As a result, non-ferric wastes and ferric wastes end up in different saidstorage carts - Compared with the prior art, the present invention discloses sensing the level of the
wastes 7 with thestorage level sensor 25 continuously, determining automatically to instruct thevibration unit 43 to shake thestorage cart 23, determining the best time to actuate thecompression unit 22 to compress thewastes 7, counting thewastes 7 automatically with thequantity sensor 24, displaying the quantity of thewastes 7 with theinterface unit 27, allowing the user to know the precise quantity of thewastes 7 cast into thestorage cart 23, enabling theticketing unit 28 to dispense thecoupon 6 required for joining a points reward scheme or receiving a cash discount or a gift so as to encourage consumers to take the initiative in recycling thewastes 7, keeping thewastes 7 at a low temperature with the freezingunit 26, and therefore enhancing the ease of compressing and freezing thewastes 7 and calculating the quantity of thewastes 7.
