Description

Technical Field

[0001] The invention belongs to the technical field of garbage bins, and in particular relates to a multifunctional automatic garbage bin. Background Art

[0002] At present, the municipal trash cans on our streets are generally the kind of inner and outer box type, with open trash openings and purely structural trash cans. This type of trash can has no electrical design and no automation.

[0003] For example, a Chinese patent document with publication number CN208249038U discloses a solid-liquid separation type municipal garbage bin, comprising a shell, a base and a bin door, wherein the base is welded to the bottom end of the shell, the bin door is axially connected to the right side of the front side of the shell, slots are opened at the top ends of the left and right sides of the shell, slideways are welded to the left and right sides of the bottom end of the inner cavity of the shell, sliders are sleeved on the outer walls of the slides, square barrels are welded to the top ends of the sliders, and the sliders are located on the left and right sides of the bottom end of the square barrel, a transparent plate is embedded in the front end of the square barrel, a U-shaped handle is screwed to the bottom end of the front end of the square barrel, a rectangular concave plate is screwed to the top end of the inner cavity of the square barrel, trapezoidal plates are screwed to the front and rear sides of the bottom end of the rectangular concave plate, and the bottom end of the trapezoidal plate is integrally formed with the bottom plate.

[0004] With the development of society, future technology will be increasingly integrated into all aspects of our lives, so the innovative application of trash cans will also develop in the direction of intelligence and automation.

[0005] Since our traditional trash cans are open and have a single function, their functions and various other garbage disposals are not so convenient. Open trash cans will emit a very unpleasant smell in the hot summer, but some pure structure flip-top trash cans are more troublesome, especially for pedestrians who are holding a lot of garbage in their hands, throwing away garbage is very troublesome.

[0006] Traditional trash cans also have a double-layer structure design with an outer shell and an inner barrel, but in many cases removing the inner barrel is a rather troublesome and messy task, and it is also time-consuming and labor-intensive, making it inconvenient for sanitation workers to collect garbage from the trash can, resulting in low operating efficiency. Summary of the invention

[0007] In order to solve the above problems existing in the prior art, the present invention provides a multifunctional automatic trash can, which can realize automatic opening and closing of the trash can, thereby preventing the odor of the trash can from being emitted and polluting the street environment.

[0008] The technical solution of the present invention is as follows:

[0009] A multifunctional automated garbage bin, comprising an outer box, an inner cylinder and a ceiling fixed to the upper part of the outer box by a column, wherein a photoelectric sensing door device is provided on the inner wall of the outer box above the inner cylinder, and a solar cell panel electrically connected to the photoelectric sensing door device is installed on the upper surface of the ceiling;

[0010] The photoelectric sensing door device comprises a photoelectric sensing transmitter, a photoelectric sensing receiver, a control panel, a driving mechanism and two horizontal sliding doors; the photoelectric sensing transmitter and the photoelectric sensing receiver are mounted on two upright posts facing each other; the driving mechanism is mounted on the inner wall of the outer box, and its output end is connected to the horizontal sliding door;

[0011] The control panel is electrically connected to the photoelectric sensor transmitter, the photoelectric sensor receiver and the driving mechanism respectively, and is used to control the driving mechanism to open the horizontal sliding door when the photoelectric sensor receiver does not receive the light signal emitted by the photoelectric sensor transmitter, and to control the driving mechanism to delay closing the horizontal sliding door when the photoelectric sensor receiver receives the light signal emitted by the photoelectric sensor transmitter again.

[0012] The present invention can effectively utilize solar energy through the solar panels on the ceiling to save energy. At the same time, compared with some flip-top trash can covers, the inductive automatic sliding door design can realize automatic opening and closing of the trash can, so that trash cans can be thrown away without flipping the cover, avoiding the odor of the trash can.

[0013] Two pulley guide rails are symmetrically arranged on the inner wall of the outer box, and sliding shafts are symmetrically fixed on two side portions of the horizontal sliding door. Both ends of the sliding shafts are provided with sliding wheels matching the pulley guide rails.

[0014] The driving mechanism comprises a driving mechanism box, a DC motor and a double-headed lead screw arranged in the driving mechanism box. The driving mechanism box is fixed to the inner wall of the outer box below the pulley guide rail. Both ends of the double-headed lead screw are fixed to the driving mechanism box through deep groove ball bearings, and both ends of the double-headed lead screw are processed with threads of opposite rotation directions. Nut sliders are symmetrically installed on the threads at both ends of the double-headed lead screw, and the upper ends of the nut sliders are respectively fixed to the bottoms of the two horizontal sliding doors.

[0015] The input end of the DC motor is electrically connected to the control board, and the output end is driven by gears, and the rotation of the motor drives the double-headed lead screw to rotate.

[0016] In order to realize that the garbage bin can automatically open and close the garbage opening, ensure that the odor of the garbage bin will not be emitted, and can automatically sense the garbage being thrown in without manually pushing the door, the present invention adopts a photoelectric sensor as a signal detection element, through which the signal is collected and the operation of the sliding door mechanism of the garbage opening of the garbage bin is controlled by a controller. The driving element of the sliding door mechanism is a DC motor, and the transmission mechanism is composed of gears and double-headed screws. The gears can increase torque and reduce speed, and the double-headed screws can realize the conversion of rotational motion into linear motion. At the same time, the garbage opening adopts double horizontal sliding doors, which can save space and facilitate automation. In order to realize synchronous movement towards and away from each other, the two horizontal sliding doors use double-headed screws with opposite thread rotation directions as the transmission center, and the screw nut mechanisms at both ends of the screws are symmetrically distributed. By connecting with the nut sliders respectively, the required functions can be realized. The sliding of the sliding door adopts a roller support mechanism, which can reduce friction and ensure multiple cycles without jamming.

[0017] The inner cylinder is an inverted cone structure, a filter screen is provided at the bottom of the inner cylinder, and a waste liquid collection box is provided at a position opposite to the filter screen. This structure enables the inner cylinder to separate some waste liquid from the garbage to avoid the waste liquid from accumulating at the bottom of the barrel, and the filter screen structure at the bottom of the barrel can facilitate the washing of the inner cylinder.

[0018] In order to make the inner cylinder easier to clean, the taper of the inner cylinder near the bottom is greater than the taper of the middle, so that the waste liquid in the garbage is effectively separated on the basis of ensuring a large capacity.

[0019] The lower part of the ceiling is provided with an LED light electrically connected to the solar panel, and the LED light adopts a light-controlled switch, and the LED light is turned on when the ambient brightness is lower than the set value. By adding the LED light, it can provide lighting for pedestrians to throw garbage at night, and provide convenience for sanitation workers to collect garbage at night.

[0020] The back of the outer box adopts a double-door structure, and a conveying mechanism support frame is symmetrically provided on two opposite side walls inside the outer box. An inner cylinder support slider is slidably fixed on the conveying mechanism support frame, and a notch is provided on the inner cylinder support slider. The upper edge of the inner cylinder is provided with a bent buckle matching the notch.

[0021] The inner cylinder supporting sliding block is provided with a spur rack on one side close to the inner wall of the outer box, and the inner wall of the outer box is provided with a stepper motor above or below the spur rack, the output shaft of the stepper motor is meshed with the spur rack through a gear, and the stepper motor is electrically connected to the control board.

[0022] In order to realize the automatic transportation of the inner barrel of the garbage bin out of the bin and into the bin, the present invention adopts a dual motor drive and a gear rack transmission to convert the rotational motion into a linear motion, which can push the slider to move. The slider and the support frame cooperate through a dovetail groove structure, which can effectively constrain the freedom of the slider and ensure that the slider can still stably perform linear motion when bearing weight. The entire mechanism has two groups, which are symmetrically installed on the side walls of the garbage bin to stably support the inner barrel of the garbage bin. The inner barrel of the garbage bin cooperates with the slider through buckles and grooves, which makes it very convenient to take out. When the transport out button is pressed, the motor drive mechanism can be controlled to drive the inner barrel of the garbage bin out, and the garbage can be cleaned up. Pressing the transport back button can control the mechanism to drag the inner barrel back to its original position.

[0023] The above arrangement enables sanitation workers to easily take out the inner barrel of the garbage bin, which is more convenient than previous garbage bins, can reduce the workload of sanitation workers in cleaning garbage and improve work efficiency.

[0024] The conveying mechanism support frame and the inner cylinder support slider are connected by a dovetail groove structure, which can limit the freedom of the slider and realize linear motion at the same time.

[0025] In the claimed transport mechanism, the inner cylinder of the garbage bin cooperates with the top notch of the inner cylinder supporting slide block through a bend buckle, and the inner cylinder is pushed in and out of the garbage bin through the movement of the inner cylinder supporting slide block.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention can effectively utilize solar energy and save energy by installing solar panels on the ceiling; by setting LED lights, it can provide lighting for pedestrians to throw garbage at night, and provide convenience for sanitation workers to collect garbage at night;

[0028] 2. The present invention can automatically detect whether there is garbage thrown into the garbage opening by setting a photoelectric sensing door device, and then control the closing and opening of the garbage opening. Compared with open garbage bins, it can prevent the odor of the garbage bin from emitting and polluting the street environment. Compared with some flip-top garbage bins, the inductive automatic sliding door design can throw away garbage without flipping the lid, which is practical and convenient.

[0029] 3. The present invention arranges a stepper motor and a conveying mechanism support frame on the inner wall of the outer box, slides and fixes an inner cylinder support slider on the conveying mechanism support frame, and arranges a straight rack on the inner cylinder support slider near the inner wall of the outer box, so that sanitation workers can easily take out the inner cylinder of the garbage bin. Compared with the previous garbage bins, it is more convenient, can reduce the workload of sanitation workers in cleaning garbage, and improve work efficiency;

[0030] 4. The present invention designs the inner cylinder into an inverted cone shape and arranges a filter screen at the bottom of the inner cylinder, so that the inner cylinder can separate some waste liquid from the garbage, thereby avoiding the accumulation of waste liquid at the bottom of the barrel. At the same time, the mesh structure at the bottom of the barrel can facilitate the flushing of the inner cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be pointed out that the embodiments described below are intended to facilitate the understanding of the present invention and do not have any limiting effect on the present invention.

[0038] like Figures 1 to 4 As shown, a multifunctional automated trash bin comprises an outer box 1, an inner tube 3 and a ceiling fixed to the upper part of the outer box 1 by columns 9. The ceiling is connected to the circular holes on the outer box 1 by the columns 9 at the four corners, which can play the role of rainproof and sun-proof. A solar panel 11 is installed on the upper surface of the ceiling. The solar panel 11 is symmetrically installed on the two inclined surfaces of the ceiling, which can absorb sunlight and generate electricity and store energy; LED lights 10 are installed on the crossbeams on the lower surface of the ceiling to provide lighting at night. A trash bin door 12 with a double-door structure is provided on the back of the box body 1. An upper cover plate 20 is provided on the inner wall of the outer box 1 at the upper end of the inner tube 3, and a garbage input port is provided in the middle of the upper cover plate 20.

[0039] The inner cylinder 3 is designed with a small taper in the middle and a large taper at the bottom, and a filter structure is set at the bottom, so that the liquid of the garbage can be effectively filtered out from the inner cylinder 3, so that the bottom of the garbage bin can be prevented from being inconvenient to clean due to the waste liquid being pushed together for a long time, and the peculiar smell can be unpleasant. This design can also be convenient for cleaning. The inner cylinder 3 is suspended on the inner cylinder suspension mechanism. The waste liquid collection box 2 is installed in the waste liquid box groove set on the outer box, and can be taken out through the handle set on the waste liquid collection box 2. The back of the outer box 1 is provided with a garbage bin door 12 of a double door structure, and the two doors are symmetrically installed on the back of the outer box, connected to the outer box 1 through a door buckle structure, and the sanitation worker can open the door through the handle on the door. The upper cover plate 20 is connected to the outer box 1 by screws, sealing the upper part of the box body, leaving only the opening for throwing garbage, which can play an isolation role.

[0040] The present invention relates to a photoelectric sensing door device, which specifically comprises: a photoelectric sensing transmitter 18, a photoelectric sensing receiver 19, a control panel, a driving mechanism 4 and two horizontal sliding doors 8. The electric sensing transmitter 18 and the photoelectric sensing receiver 19 are mounted on two uprights 9 opposite to each other, so as to ensure that it can sense whether garbage is thrown in and timely control the horizontal sliding door 8 to open. The driving mechanism 4 is mounted on the inner wall of the outer box, and its output end is connected to the horizontal sliding door.

[0041] The control panel is electrically connected to the photoelectric sensor transmitter 18, the photoelectric sensor receiver 19 and the driving mechanism 4 respectively, and is used to control the driving mechanism 4 to open the horizontal sliding door 8 when the photoelectric sensor receiver 19 does not receive the light signal emitted by the photoelectric sensor transmitter 18, and to control the driving mechanism to delay closing the horizontal sliding door 8 when the photoelectric sensor receiver 19 receives the light signal emitted by the photoelectric sensor transmitter 18.

[0042] like Figure 1 As shown, two pulley rails 5 are symmetrically provided on the inner wall of the outer box 1, and sliding shafts 7 are symmetrically fixed on the two sides of the horizontal sliding door 8. Both ends of the sliding shaft 7 are provided with sliding wheels 6 matching the pulley rails 5. In order to ensure that the horizontal sliding door 8 can slide stably on the pulley rails 5, in this embodiment, four sliding shafts 7 and eight sliding wheels 6 are provided under each horizontal sliding door 8, so as to realize the stable movement of the two horizontal sliding doors 8 towards and away from each other.

[0043] like Figure 5As shown, it is a schematic diagram of the specific structure of the driving mechanism 4, including a driving mechanism box 41 and a DC motor 42 and a double-headed lead screw 46 arranged in the driving mechanism box 41. The driving mechanism box 41 is fixed on the inner wall of the outer box 1 below one of the pulley guide rails 5. The two ends of the double-headed lead screw 46 are fixed to the driving mechanism box 41 through deep groove ball bearings 45, and threads with opposite rotation directions are provided near the two ends; nut sliders 47 are symmetrically installed on the threads at both ends of the double-headed lead screw 46, and the upper ends of the nut sliders 47 are respectively fixed to the bottoms of the two horizontal sliding doors 8; the input end of the DC motor 42 is electrically connected to the control board, and a small gear 43 is fixed to its output end. A large gear 44 is fixed to one end of the double-headed lead screw 46, and the DC motor 42 is connected to the double-headed lead screw 46 through gear meshing.

[0044] More specifically, the DC motor 42 is matched with the motor seat of the drive mechanism housing 41 and fixed by screws. The pinion 43 is connected to the motor shaft of the DC motor 42 and is positioned circumferentially by a common flat key and axially by a shaft shoulder. The large gear 44 is connected to the double-headed screw 46 and is positioned axially by a shaft shoulder and circumferentially by a common flat key. Two deep groove ball bearings 45 are symmetrically installed on the bearing holes of the drive mechanism housing 41, and are positioned with the shaft shoulder of the double-headed screw 46 to stably support the double-headed screw 46, ensuring that the motor can efficiently drive the rotation of the double-headed screw 46. The nut slider 47 is symmetrically mounted on the threads at both ends of the double-ended lead screw 46, and the threads cooperate with each other. At the same time, the upper part of the nut slider 47 cooperates with the notch of the driving mechanism box cover 48 to ensure that the nut slider 47 can slide stably in the horizontal direction. The two nut sliders 47 are symmetrically distributed at both ends of the double-ended lead screw 46. The different rotation directions of the threads can realize that the nut sliders 47 move toward and away from each other synchronously. Then the nut slider 47 is fixed to the horizontal sliding door 8 by screws, so that the horizontal sliding door 8 can move synchronously with the nut slider 47. The driving mechanism box cover 48 is connected with the driving mechanism box body 41 and fixed by screws, which can isolate and protect the internal parts to a certain extent. The driving mechanism box body 41 is fixed to the outer box 1 by screws to fix and support the driving mechanism of the entire sliding door.

[0045] like Figure 2 and Figure 3As shown, the present invention also designs an inner cylinder conveying mechanism, which includes two conveying mechanism support frames 13, two inner cylinder support sliders 14, two spur racks 15, two M1 gears 16, two stepping motors 17 and other parts. The conveying mechanism support frame 13 is fixed to the installation position of the outer box 1 by screws, and the two pieces are symmetrically distributed on the two symmetrical surfaces of the trash can to sufficiently support the weight of the fully loaded inner cylinder 3. The inner cylinder support slider 14 is assembled on the conveying mechanism support frame 13, and the two are connected by a dovetail groove structure, which can not only ensure that the inner cylinder support slider 14 slides stably on the conveying mechanism support frame 13, but also play a restraining role, so that the inner cylinder support slider 14 can stably perform linear motion. The spur rack 15 is installed inside the groove of the inner cylinder support slider 14 and fixed by small screws to ensure that the spur rack 15 will not loosen under the action of force and can transmit stably. The M1 gear 16 is installed on the output shaft of the stepper motor 17, and the shaft end is fixed by a fastening nut. The stepper motor 17 is placed vertically and fixed on the outer box 1. The stepper motor 17 transmits power through a gear rack mechanism to drive the inner cylinder support slider 14 to slide horizontally on the conveying mechanism support frame 13. The use of two sets of symmetrically distributed drive mechanisms can effectively disperse the driving resistance and ensure that the motor has enough power to drive the fully loaded inner cylinder 3. The inner cylinder 3 is suspended in the notch of the inner cylinder support slider 14 through the curved buckle design on the edge. As the inner cylinder support slider 14 slides, it can automatically and stably come out of the side door of the outer box 1, solving the problem that it is difficult for sanitation workers to take out the inner cylinder of the trash can, and it can be taken out automatically. The worker directly lifts the trash can through the side handle of the inner cylinder 3, dumps the garbage, and then puts the inner cylinder 3 back to the previous position. The inner cylinder 3 is automatically transported to the inside of the outer box 1 by the conveying mechanism. When the stepper motor 17 drives the inner cylinder support slider 14 to slide outward on the conveying mechanism support frame 13, it can ensure that the inner cylinder support slider 14 and the conveying mechanism support frame 13 always have a safe dovetail groove contact distance, and can stably support the entire weight. The inner cylinder 3 only needs to be more than half out, and the sanitation worker can touch the handle to lift it out, which is very convenient to use.

[0046] like Figure 6 As shown, the multifunctional automated trash bin of the present invention controls the process when in use. In the figure, the straight line represents power supply, the arrow represents signal transmission, ① and ② represent two different signal controls, ① represents the sliding door mechanism control, and ② represents the transport mechanism control.

[0047] The specific use can be divided into the following steps:

[0048] Step 1: Assemble the entire multifunctional automated trash bin according to the design instructions;

[0049] Step 2: The solar panel 11 can store energy after being irradiated by sunlight, which can be used by the electrical components of the multifunctional automated trash bin;

[0050] Step 3: The pedestrian throws garbage now, the light signal emitted by the photoelectric sensor transmitter 18 is blocked by the garbage, and the photoelectric sensor receiver 19 does not receive the light signal, and generates a control signal to control the DC motor 42 to rotate forward, and then drives the two horizontal sliding doors 8 to move away from each other through the driving component, and the garbage opening of the garbage bin is opened;

[0051] Step 4: The pedestrian throws the garbage into the inner tube 3, waits for a while to ensure that the pedestrian can completely throw away the garbage in his hand, and then the delay control function controls the DC motor 42 to reverse, and the horizontal sliding doors 8 move towards each other through the driving member to ensure that the two horizontal sliding doors 8 can be completely fitted, and the DC motor 42 stops moving;

[0052] Step 5: Generally, sanitation workers clean up urban garbage at night, and the LED light 10 is turned on at this time. The worker opens the garbage bin door 12, presses the button, turns on the garbage bin conveying mechanism, controls the conveying mechanism to move through the stepper motor 17, and conveys the inner cylinder 3 out of the garbage bin. The sanitation worker holds the handle of the inner cylinder 3 and dumps the garbage in the garbage bin into the centralized garbage truck. After rinsing, the inner cylinder 3 is put back into the groove of the inner cylinder support slider 14;

[0053] Step 6: Open the trash bin transport mechanism, reverse the stepper motor 17, and transport the inner tube 3 back to the trash bin. Then close the trash bin door 12. Pull out the waste liquid collection box 2 from the bottom of the trash bin, pour out the waste liquid inside, and then put it back into the trash bin after rinsing.
