Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal machinery and equipment, and in particular to an automatic cleaning and intelligent access system for public household garbage cans. Background Art

[0002] my country currently implements the four-classification of garbage, namely kitchen waste, other garbage, recyclables and hazardous waste. The focus is to separate kitchen waste from domestic waste and recycle it separately. Unlike neighboring Japan, the four-classification method is a rough classification method. We believe that through the large classification at the resident end and the secondary sorting of the back-end disposal equipment, the social cost is low and the resource utilization rate is high. It is currently the first choice for solving the problem of garbage reduction, resource utilization and harmlessness.

[0003] In traditional garbage sorting and delivery, plastic garbage bags are generally used as the carrier of circulation, and the same is true for kitchen waste. This brings great problems to garbage sorting. First, plastic bags themselves do not belong to kitchen waste. Second, in the process of garbage promotion, identifying and evaluating the quality of garbage sorting is a very important task. The use of plastic bags makes the evaluation process very difficult. In response to the above problems, various places have also introduced corresponding measures to limit the flow of plastic bags into the kitchen waste sorting and disposal system. The main methods are: relying on sharp tools to let users break the bags themselves and then put in kitchen waste, and the broken plastic bags are put into other garbage (Shanghai, Fuyang); let middlemen break the bags to improve the accuracy of garbage entering the bin (some areas in Ningbo). At present, the promotion of these two methods faces great problems. Self-breakage of bags will increase the danger in public places. There have been several cases of children being injured while playing; and third-party bag breaking has greatly increased the personnel input in garbage sorting, the social cost is huge, and it cannot be reduced in the short term.

[0004] In order to solve these problems, users are required not to use garbage bags, but to put the garbage directly into the household garbage can, and then directly pour the garbage into the transfer garbage can. During the recycling process of these used household garbage cans, the debris in the barrel needs to be cleaned, otherwise it will affect the family's use. The existing cleaning method is to put the cleaning liquid into the waste barrel, and then use a manual method to clean it with a brush. This method has a large number of garbage cans and is inconvenient to clean inside. The labor intensity of the workers is high and the work efficiency is low. Moreover, if the original barrel contents are harmful chemical reagents, it is easy to cause harm to the workers and affect the workers' health. At the same time, the quality of cleaning is difficult to guarantee. Summary of the invention

[0005] In view of this, the present invention provides an automatic cleaning and intelligent retrieval system for public household trash cans that is conducive to automatic cleaning to meet the above needs.

[0006] A public household trash can automatic cleaning and intelligent access system, wherein the trash can cleaned and accessed includes a barrel body and an L-shaped flange arranged outward from the barrel body. The public household trash can automatic cleaning and intelligent access system includes a frame, a flipping mechanism arranged in the frame, a cleaning mechanism arranged in the frame, an access mechanism for accessing the trash can, and an intelligent control module electrically connected to the flipping mechanism, the cleaning mechanism, and the access mechanism. The flipping mechanism includes two brackets respectively rotatably arranged on two opposite side walls of the frame, a barrel rack mounted on the two brackets, and a driving mechanism driving the bracket to flip 180 degrees. The barrel rack includes a through hole and a step arranged on the side wall of the through hole. The L-shaped flange is mounted on the step. The driving mechanism includes a gear connected to the bracket and a motor driving the gear to rotate. The cleaning mechanism includes a water receiving tray, a scraper arranged at the center of the water receiving tray, a water spraying rod arranged at the center of the water receiving tray, a rotation driving device for driving the scraper to rotate, and an up-down driving device for driving the water receiving tray to reciprocate toward the turning mechanism. The scraper is a frame-shaped structure and the width of the frame-shaped structure is equivalent to the inner diameter of the barrel body. The water spraying rod is used to spray water to the inner side wall of the barrel body during the rotation of the scraper. The rotation driving mechanism is arranged on the water receiving tray and drives the scraper to rotate. The up-down driving device includes two sliders respectively arranged on two opposite side walls of the frame, and two driving motors respectively driving the sliders to reciprocate toward the turning mechanism. The water receiving tray is fixedly mounted on the slider. The access mechanism includes a two-dimensional driving mechanism and a clamping frame arranged on the two-dimensional driving mechanism. The two-dimensional driving mechanism drives the clamping frame to be inserted between the L-shaped flange and the barrel body to clamp the trash can. The intelligent control module is used to control the turning mechanism, the cleaning mechanism, and the access mechanism to work automatically and orderly.

[0007] Furthermore, the driving mechanism also includes two pivots respectively inserted on the gears.

[0008] Furthermore, the flipping mechanism further comprises a clamping mechanism, and the clamping mechanism comprises cams respectively arranged on the pivots, and the cams are rotationally connected to the corresponding pivots and fixed on the frame.

[0009] Furthermore, the cam has the same structure and includes a body and a boss protruding along the axial direction of the pivot.

[0010] Furthermore, the central angle of the boss is 180 degrees.

[0011] Furthermore, the clamping mechanism also includes two levers respectively accommodated in the bracket, the lever is pivotally connected to the bracket, and a push rod is provided at one end of the lever. When the bracket drives the lever to rotate 180 degrees every time, the push rod switches between the boss and the main body.

[0012] Furthermore, the clamping mechanism also includes two plug plates respectively pivotally connected to the levers, the plug plates are L-shaped, and one side of the L-shaped plug plate is pivotally connected to one end of the lever.

[0013] Furthermore, the clamping mechanism also includes a return spring arranged on the shaft where the lever and the bracket are pivotally connected, and the return spring is a trigger spring.

[0014] Furthermore, a soft scraper strip is clamped on the scraper.

[0015] Furthermore, the rotary drive device is fixedly arranged on the water receiving tray.

[0016] Compared with the prior art, the public household trash can automatic cleaning and intelligent access system provided by the present invention has the flip mechanism, the cleaning mechanism, and the access mechanism, and the automatic cleaning and intelligent access system can also have an intelligent control module, which can automatically control the operation of the above-mentioned functional modules. When in use, the user can directly send the trash can into the flip mechanism and place it on the bucket rack, and then the driving mechanism drives the bucket rack to flip so that the opening of the trash can faces the cleaning mechanism, and the upper and lower driving mechanisms of the cleaning mechanism drive the water receiving tray to move toward the trash can, and then the rotating driving mechanism drives the scraper to rotate to scrape the inner wall of the trash can, and the water spraying rod sprays water to clean the inside of the trash can while scraping. Of course, after the cleaning is completed, the scraper stops rotating and spraying water, and then the cleaning mechanism is moved down, the trash can is flipped, and finally the access mechanism takes out the trash can and places it on the access rack or the user directly takes the trash can away, so that the automatic cleaning and automatic access of the trash can can be realized, eliminating the heavy labor of manual cleaning and avoiding the bad working environment, and also providing cleaning efficiency.

[0022] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0023] like Figures 1 to 5 As shown, it is a structural schematic diagram of the automatic cleaning and intelligent access system for public household garbage cans provided by the present invention. The garbage can 200 for cleaning and accessing the automatic cleaning and intelligent access system for public household garbage cans includes a barrel body 201, and an L-shaped flange 202 arranged outward from the barrel body 201. The garbage can 200 can be made of plastic, metal and other materials through injection molding, die casting and other processes. The L-shaped flange 202 is arranged on the outside of the barrel body 201 and extends away from the center of the barrel body 201. The automatic cleaning and intelligent access system for public household garbage cans includes a frame 10, a turning mechanism 20 arranged in the frame 10, a cleaning mechanism 30 arranged in the frame 10, and an access mechanism 40 for accessing the garbage can 200, and an intelligent control module 50 electrically connected to the turning mechanism 20, the cleaning mechanism 30, and the access mechanism 40. It is conceivable that the public household trash can automatic cleaning and intelligent retrieval system also includes some other functional modules, such as assembly components, installation components, and electrical connection components, etc., which are technologies well known to those skilled in the art and will not be repeated here.

[0024] The frame 10 is used to accommodate or set up the flipping mechanism 20, the cleaning mechanism 30, and the intelligent control module 50, so its shape and structure should be designed accordingly according to the shapes and structures of the flipping mechanism 20, the cleaning mechanism 30, and the intelligent control module 50, and therefore will not be described in detail here.

[0025] The flip mechanism 20 includes two brackets 21 rotatably arranged on two opposite side walls of the frame 10, a barrel rack 22 mounted on the two brackets 21, a clamping mechanism 23 arranged on the bracket 21, and a driving mechanism 24 driving the bracket to flip 180 degrees. The two brackets 21 have the same structure, one end of any one of the brackets 21 is arranged on the frame 10 by including the driving mechanism 24, and the other end is connected to the barrel rack 22 to mount the barrel rack 22. The barrel rack 22 includes a through hole 221 and a step 222 arranged on the side wall of the through hole 221. The through hole 221 is used to accommodate the open end of the trash can 200. The L-shaped flange 202 is mounted on the step 222 to maintain the positional relationship between the trash can 200 and the barrel rack 22. The driving mechanism 24 includes two pivots 241 arranged on the frame 10 and passing through one end of the bracket 21, and a gear 242 fixed to one of the pivots 241. The pivot 241 is fixedly arranged with the bracket 21 and the gear 242, so that when the gear 242 rotates, the bracket 21 can be driven to rotate. It can be imagined that the driving mechanism 24 also includes a motor and a belt connecting the motor and the gear 242, but it is a prior art and will not be described here. Because the trash can 200 only needs to maintain the two states of upright and inverted, the driving mechanism 24 only needs to drive the gear 242 and the bracket 21 to flip 180 degrees in each movement to achieve the above-mentioned two states of upright and inverted. The clamping mechanism 23 is used to prevent the trash can 200 from detaching from the barrel rack 22 when the trash can 200 is placed in the through hole 221 and during the flipping process. The clamping mechanism 23 includes two cams 231 respectively arranged on the pivot 241, two levers 232 respectively accommodated in the bracket 21, two plug plates 233 respectively pivoted with the levers 232, and a return spring 234 arranged on the shaft where the lever 232 and the bracket 231 are pivoted. The cam 231 is sleeved on the pivot 241 and fixed on the frame 10, that is, the position of the cam 231 is fixed. The cam 231 includes a body 2311 and a boss 2312 protruding along the axial direction of the pivot 241. Because the angle of each rotation of the bracket 21 is 180 degrees, the central angle of the boss 2312 is 180 degrees, so that when the bracket 21 rotates each time, the lever 232 and the boss 2312 can be switched between contact and discontinuity. The lever 232 is accommodated in the bracket 21 and pivoted in the bracket 21. It is conceivable that in order to pivot the lever 232, an axis should be provided between the lever 232 and the bracket 21 to connect, but this is a prior art and will not be described in detail. An abutting rod 2321 is provided at one end of the lever 232.When the bracket 21 drives the lever 232 to rotate 180 degrees, the push rod 2321 switches between the boss 2312 and the body 2312. The other end of the lever 232 is provided with a sleeve 2322. The sleeve 2322 is connected to the plug plate 233. The plug plate 233 is an L-shaped structure. One side of the plug plate 233 of the L-shaped structure is connected to the lever 232, that is, the plug plate 233 and the sleeve 2322 are also pivotally connected, so that the plug plate 233 is rotatably connected to the lever 232. During operation, when the gear 242 drives the bracket 21 to rotate through the pivot 241, and when the push rod 2321 contacts the boss 2312, the other end of the lever 232 will push the other side of the plug plate 233 to extend from the side wall of the through hole 221, thereby achieving the purpose of clamping the L-shaped flange 202 together with the step 222, and further achieving the purpose of fixing the barrel rack 22 and the trash can 200, so that the trash can will not fall when it is turned over. When the push rod 2321 contacts the body 2311, the other end of the lever 232 will drive the other side of the plug plate 233 to retract from the side wall of the through hole 221, thereby releasing the purpose of clamping the L-shaped flange 202 together with the step 222. The reset spring 234 can be a trigger spring, one end of which is against the bracket 21 and the other end is against the lever 232. When the push rod 2321 contacts the body 2311 of the cam 231 , the return spring 234 can press the push rod 2321 onto the body 2311 to ensure that the other side of the inserting plate 233 is retracted from the side wall of the through hole 221 .

[0026] The cleaning mechanism 30 includes a water receiving tray 31, a scraper 32 arranged at the center of the water receiving tray 31, a water spraying rod 33 arranged at the center of the water receiving tray 31, a rotating driving device 34 for driving the scraper 32 to rotate, and two upper and lower driving devices 35 for driving the water receiving tray 31 to reciprocate toward the turning mechanism 20. The water receiving tray 31 is used to receive and collect sewage falling during the cleaning process of the garbage can 200, and discharge it through a sewage pipe specially arranged on the water receiving tray 31. The structure and shape of the water receiving tray 31 can be set according to actual needs. The scraper 32 is rotatably arranged on the water receiving tray 31. It can be imagined that, in order to facilitate installation and sealing, the scraper 32 is also provided with a bearing assembly and a sealing assembly, which is a prior art and will not be repeated here. In order to closely contact with the inner wall of the barrel to more easily clean the inner wall of the barrel, the scraper 32 is also sandwiched with a soft scraper strip and the scraper 32 can be a frame-shaped structure and the width of the frame-shaped structure is equivalent to the inner diameter of the barrel body 201. The water spray rod 33 is fixedly arranged on the water receiving tray 31 and is sealed with the water receiving tray 31, so that the water spray rod 33 moves up and down together with the water receiving tray 31. A plurality of fine holes can be arranged on the water spray rod 33, so that a torrent is formed under water pressure to achieve the purpose of flushing. The rotation drive device 34 is arranged on the water receiving tray 31 to move with the water receiving tray 31. The rotation drive device 34 is used to drive the scraper 32 to rotate and includes a sleeve 341 connected to the scraper 32, and a motor assembly 342 that drives the sleeve 341 to rotate. The sleeve 341 is fixedly connected to the scraper 32 and is arranged on the water receiving tray 31 through a bearing assembly, so that the scraper 32 can rotate relative to the water receiving tray 31. The motor assembly 342 includes a motor, gears, belts, etc., which are well known to those skilled in the art and are not repeated here. Each of the up and down driving devices 35 includes a guide rail 351 arranged on the frame 10, a slider 352 fixedly arranged on both sides of the water receiving tray 31 and slidably arranged on the guide rail 351, and a driving assembly 353 driving the slider 352 to move up and down. The guide rail 351 is vertically arranged on the frame 10. The slider 352 and the guide rail 351 should be prior art and will not be described in detail here. The driving assembly 353 includes a motor, a belt with teeth, and two gears arranged at intervals. The motor drives one of the gears to rotate, thereby driving the belt to rotate around the two gears. At the same time, teeth coupled with the teeth of the belt are also arranged on both sides of the slider 352, so that when the belt rotates forward or reversely, the slider 352 and the water receiving tray 31 connected to the slider 352 can be driven to slide back and forth up and down. When the water receiving tray 31 moves to the top and the scraper 32 is inserted into the garbage can 200, the scraper 32 can be driven to rotate.

[0027] The storage and retrieval mechanism 40 includes a stand 41, a two-dimensional driving mechanism 42 arranged on the stand 41, and a clamping frame 43 arranged on the two-dimensional driving mechanism 42. The stand 41 can be placed on the ground to support the two-dimensional driving mechanism 42. The two-dimensional driving mechanism 42 should be a prior art, which can be composed of a guide rail pair, a screw, and a motor. When the motor is turned on to drive the screw to rotate, it drives the guide rail pair to move, thereby achieving the purpose of moving along a specified trajectory. In this embodiment, the two-dimensional driving mechanism 42 drives the clamping frame 43 to move in the horizontal and vertical directions, so that the clamping frame 43 can place the trash can 200 on the bucket rack 22, or remove the trash can 200 from the bucket rack 22. The clamping frame 43 includes two clamping rods arranged at intervals, which can be made of metal. The distance between the two clamping rods is less than the diameter of the opening of the trash can 200, so that the clamping frame 43 can be used to clamp the trash can 200 to achieve the purpose of storage and retrieval.

[0028] The intelligent control module 50 may include a single chip microcomputer or a programmable controller, so that the start time and start duration of each motor can be controlled by programming, so as to make the flip mechanism 20, the cleaning mechanism 30, and the access mechanism 40 work in an orderly manner. This should be the prior art and will not be described in detail here. As long as those skilled in the art understand the working principle of the present invention, they can compile a corresponding control program to control the working state of the flip mechanism 20, the cleaning mechanism 30, and the access mechanism 40 in an orderly manner.

[0029] Compared with the prior art, the automatic cleaning and intelligent storage and retrieval system for public household trash cans provided by the present invention has the flipping mechanism 20, the cleaning mechanism 30, and the storage and retrieval mechanism 40. At the same time, the automatic cleaning and intelligent storage and retrieval system can also have an intelligent control module 50, which can automatically control the operation of the above-mentioned various functional modules. When in use, the user sends the trash can 200 into the flipping mechanism 20 and places it on the bucket rack 22, and then the driving mechanism 24 drives the bucket rack 22 to flip so that the opening of the trash can 200 faces the cleaning mechanism 30, and the up and down driving mechanism 35 of the cleaning mechanism 30 drives the water receiving tray 31 to move toward the trash can 200, and then the rotating driving mechanism 34 drives the scraper 32 to rotate to scrape the inner wall of the trash can 200, and at the same time, the water spraying rod 33 sprays water to clean the inside of the trash can 200. Of course, after cleaning is completed, the scraper 32 stops rotating and spraying water, and then the cleaning mechanism 30 is moved down, the trash can 200 is flipped, and finally the storage and retrieval mechanism 40 takes out the trash can 200 and places it on the storage and retrieval rack or the user directly takes the trash can away, thereby realizing automatic cleaning and automatic retrieval of the trash can 200, eliminating the heavy labor and harsh working environment of manual cleaning, and also providing cleaning efficiency.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
