Description

Technical Field

[0001] The present invention relates to the technical field related to household appliances, and in particular to an intelligent trash can and an operating method of the intelligent trash can. Background Art

[0002] Smart trash cans are still in their infancy. The sheer variety of single-function options leaves consumers overwhelmed and hesitant to purchase them, often with concerns about quality and reliability. This has significantly hampered their development. Functionality is incomplete, lacking intelligence, safety, and reliability. The market is flooded with a large number of single, fragmented smart trash cans. Most offer only infrared sensing for opening the lid and lack fully integrated automatic bagging, packaging, and compression. This focus on single-function intelligence, without prioritizing fundamental safety, quality, and reliability, has led to a high prevalence of defective products on the market, discouraging purchases.

[0003] Few existing technologies address environmentally friendly and non-toxic waste management by providing automated bagging, compression, and packaging solutions. Publication No. CN109606993A merely monitors the level of garbage accumulation in real time through a smart terminal and automatically senses the opening and closing of a smart trash can. An infrared ranging sensor monitors the level of garbage accumulation in real time, and a microprocessor sends a door-opening or door-closing instruction to a drive device, which in turn drives the sensor door of the smart trash can to open or close, thereby enabling real-time monitoring of the smart trash can in the home. Existing technologies only address the opening and closing of garbage, still requiring manual intervention for bagging, resulting in a low level of automation.

[0049] Example 1

[0050] In order to solve the problems in the prior art of smart trash cans that have single functions, require a lot of manual participation, and have poor user experience, the present invention provides a smart trash can.

[0051] like Figures 1 to 3 As shown, the smart trash can includes a barrel body 10, a trash bag storage box 20 and a sealing part 30. The barrel body 10 has a trash receiving chamber 121 and an opening at the top of the trash receiving chamber 121. The trash bag storage box 20 is arranged at the opening. The trash bag storage box 20 has an annular placement chamber 210 and a bag delivery port for connecting the annular placement chamber 210 and the trash receiving chamber 121. The bag delivery port is continuously arranged around the annular placement chamber 210. The sealing part 30 is arranged below the trash bag storage box 20. The sealing part 30 includes a movable sealing structure 310. The sealing structure 310 has an avoidance position for avoiding the opening and a sealing position for sealing the trash bag after movement.

[0052] Specifically, in the present application, the garbage bag is accommodated inside the garbage bag storage box 20, and the garbage bag storage box 20 is placed at the top opening of the garbage storage chamber 121 to facilitate the disassembly and assembly of the garbage bag storage box 20; at the same time, the sealing part 30 located below the garbage bag storage box 20 can control the sealing structure 310 to move between the avoidance position and the sealing position. When in the avoidance position, it does not affect the garbage from entering the garbage storage chamber 121, and when in the sealing position, the garbage bag is sealed. The setting of the sealing structure 310 realizes the sealing of the bag through movement, reduces manual participation, and improves intelligence.

[0053] It should be noted that the garbage bag used in conjunction with the smart trash can of the present application is a cylindrical structure garbage bag with openings at both ends. The garbage bag is rolled from one open end to the other open end to form an annular garbage bag roll. The garbage bag roll is placed inside the annular placement cavity 210 of the garbage bag storage box 20, and one of the open ends of the garbage bag is pulled out from the bag delivery port to the inside of the garbage receiving cavity 121.

[0054] Furthermore, the garbage bag storage box 20 is annular and has a delivery channel, which is connected to the top opening of the garbage receiving chamber to facilitate delivery of garbage into the garbage receiving chamber 121.

[0055] Among them, this embodiment provides two implementation methods according to the different locations of the bag delivery port, as follows.

[0056] In a specific embodiment of the present application, the bag delivery port is provided at the bottom of the garbage bag storage box 20 to facilitate pulling one open end of the garbage bag into the interior of the garbage receiving cavity 121 .

[0057] In another specific embodiment of the present application, the bag delivery port is provided on the side wall of the inner ring of the garbage bag storage box 20 , so that one open end of the garbage bag is pulled into the interior of the garbage receiving cavity 121 .

[0058] In this embodiment, the garbage bag storage box 20 is detachably mounted at the opening of the barrel body 10, so that the garbage bag storage box 20 can be removed and the garbage bag can be placed into the placement cavity. The top plate or bottom plate of the garbage bag storage box 20 is detachably connected to the side plate of the garbage bag storage box 20, so that the garbage bag can be placed into the placement cavity by opening the top plate or bottom plate of the garbage bag storage box 20.

[0059] like Figures 1 to 3 As shown, the sealing structure 310 is a sealing strip having a heating element, and the sealing strip can move laterally along the barrel body 10 .

[0060] Specifically, the sealing strip moves to clamp the open end of the garbage bag, and the heating element performs heat sealing to achieve the sealing operation of the garbage bag. When the sealing strip does not need to be sealed, the sealing strip is set close to the edge and does not affect the input of garbage.

[0061] Furthermore, there are two sealing strips, which are staggered and can move in two different directions, so that one of the open ends of the garbage bag can be clamped by the two sealing strips, and the two sealing strips facilitate the sealing operation.

[0062] Furthermore, the sealing portion 30 further includes a mounting frame, the sealing structure 310 is slidably arranged relative to the mounting frame, and the packaging strip moves inside the area formed by the mounting frame.

[0063] It should be noted that, along the height direction of the barrel body 10 , the packaging strip is located in the area between the open end of the garbage receiving cavity 121 and the bag delivery port of the garbage bag storage box 20 .

[0064] Furthermore, the two packaging strips are perpendicular to each other so that both packaging strips can move from one side of the mounting frame to the other side, and the two packaging strips are spaced apart in the height direction, thereby clamping the opening of the garbage bag at the corners of the two packaging strips and the mounting frame, and sealing is achieved by the heating element.

[0065] like Figures 1 to 3 As shown, the sealing portion 30 further includes a bag pressing assembly 320 , which is installed on the packaging strip in an adjustable position.

[0066] Among them, the bag pressing assembly 320 includes a mounting body 321, a transmission member 322, a pushing plate 324 and a pushing drive assembly. At least a portion of the mounting body 321 is mounted on the packaging strip and is slidably connected to the packaging strip. The pushing drive assembly is installed on the mounting body 321. The pushing drive assembly has a first drive member and a second drive member 323. The first drive member is driven and connected to the packaging strip through the transmission member 322. The second drive member 323 is driven and connected to the pushing plate 324. The second drive member 323 provides driving force for the pushing plate 324 to move along the depth direction of the barrel body 10. The pushing plate 324 is used to push the garbage in the garbage bag.

[0067] Specifically, the pushing plate 324 can move downward under the drive of the second driving member 323 of the pushing driving assembly, and the garbage is pressed downward by the pushing plate 324.

[0068] Furthermore, the push plate 324 is arranged in a rectangular structure, the packaging strip has a rack arranged along the length direction, and the transmission member 322 is a transmission gear, which is engaged with the rack.

[0069] It should be noted that the first driving member is a rotating motor or a rotating cylinder to realize the rotational connection between the driving transmission gear and the rack, thereby realizing the adjustment of the position of the bag pressing assembly 320; the second driving member 323 can be a telescopic motor or a telescopic cylinder or an electric telescopic rod, so as to realize the telescopic movement of the driving push plate 324, so as to facilitate the pressing down or releasing of the pressed garbage.

[0070] In this embodiment, to drive the packaging strips to move laterally, a motor that cooperates with the packaging strips is provided on the push plate 324. The motor drives the packaging strips to move. If two packaging strips are provided, two corresponding motors are provided to drive the packaging strips to move. The motor-driven movement of the packaging strips can be achieved by using a conveyor belt and gears, where the motor drives the gears provided on the mounting frame to rotate, which in turn drives the conveyor belt, which in turn drives the packaging strips to move. Alternatively, the motor-driven movement of the packaging strips can be achieved by using a lead screw 430, where the motor drives the lead screw 430 to rotate, and the lead screw 430 cooperates with the threaded connection of the packaging strips to drive the packaging strips to move.

[0071] like Figures 1 to 3 As shown, the smart trash can further includes a bag pulling assembly 40 , which is liftably disposed on the barrel body 10 .

[0072] Specifically, the bag pull assembly 40 is used to absorb the garbage bag, so that the garbage bag is moved into the garbage receiving chamber 121 by lowering the bag pull assembly 40. The smart trash can of the present application can also realize the placement of the garbage bag by pulling the garbage bag into the garbage receiving chamber 121 through the bag pull assembly 40 without manual intervention, thereby improving the user experience.

[0073] Furthermore, the bag pulling assembly 40 includes a pickup portion and a lifting portion. The pickup portion is capable of picking up or releasing a garbage bag. The pickup portion is disposed on the lifting portion and moves in the depth direction of the barrel body 10 as the lifting portion moves. During the bag pulling operation, the pickup portion picks up the garbage bag so that the garbage bag and the pickup portion move synchronously. The lifting portion is used to drive the pickup portion to move up and down within the garbage receiving chamber 121 in the barrel body 10.

[0074] Furthermore, the picking part includes a suction nozzle 460 and an air suction pipe 450 connected to the suction nozzle 460, and the garbage bag is picked up by the air nozzle and the garbage bag being adsorbed, wherein the air suction pipe 450 is connected to the air pump to realize the air extraction operation through the air pump.

[0075] In this embodiment, the barrel body 10 includes an inner barrel body 120 and an outer shell 110. The inner barrel body 120 is arranged in the outer shell 110 and forms a clamping cavity 140 between the two. The lifting part is accommodated in the clamping cavity 140. The inner barrel body 120 has a channel connecting the garbage accommodating cavity 121 and the clamping cavity 140.

[0076] The bag pulling assembly 40 further includes a telescopic portion, which is arranged transversely and connected to the lifting portion at one end and the picking portion at the other end, so as to adjust the position of the picking portion within the barrel body 10. The telescopic portion can drive the picking portion through the channel into the interior of the garbage receiving chamber 121 to pick up the garbage bag inside the garbage receiving chamber 121.

[0077] like Figures 1 to 3 As shown, the barrel body 10 includes an outer shell 110, a partition 130 and an inner barrel body 120. The partition 130 is arranged in the outer shell 110 to separate the internal space of the outer shell 110 into an upper space and a lower space. The lower space is an electrical chamber 150. The inner barrel body 120 is arranged in the upper space. A clamping chamber 140 is formed between the inner barrel body 120 and the outer shell 110. The inner barrel body 120 has a garbage holding chamber 121.

[0078] Specifically, the telescopic portion moves up and down inside the clamping cavity 140 , and the lifting drive portion 410 of the lifting portion is located inside the electrical cavity 150 to protect the lifting drive portion 410 .

[0079] Furthermore, the lifting part includes a lifting drive part 410, a screw 430 and a slider 440. The lifting drive part 410 is installed inside the electrical cavity 150. The lifting drive part 410 is driven and connected to one end of the screw 430. The other end of the screw 430 passes through the partition 130 and extends into the interior of the clamping cavity 140. The slider 440 is movably arranged on the screw 430. The picking part and the air pump of the bag pulling assembly 40 are connected to the slider 440.

[0080] Among them, the lifting drive unit 410 is a rotating motor. The lifting drive unit 410 changes the rotation direction of the output shaft to realize the up and down movement of the driving slider 440. In order to ensure the stable connection between the driving member and the screw 430, a coupling 420 is arranged between the screw 430 and the output shaft of the driving member.

[0081] In this embodiment, to ensure that the garbage bag can stably enter the garbage storage chamber 121, the bottom surface of the inner barrel 120 is provided with an air intake hole 131. The smart garbage collection system also includes a fan pump installed within the electrical chamber 150, with the air intake of the fan pump communicating with the air intake hole 131. After the garbage bag enters the garbage storage chamber 121 under the drive of the pickup unit, the fan pump extracts air from the garbage storage chamber 121, providing a driving force for the garbage bag to adhere to the bottom surface of the inner barrel 120.

[0082] It should be noted that the smart trash can also includes a puncture portion, which is arranged inside the trash receiving cavity 121 and is used to puncture the trash bag. The puncture portion can be a thimble arranged on the bottom surface of the inner barrel 120 to puncture the air guide hole of the trash bag.

[0083] Furthermore, the smart trash can also includes a gravity sensor, which is installed on the bottom surface of the barrel body 10 to detect weight information.

[0084] Furthermore, the smart trash can further includes a gyroscope sensor, which is mounted on the sealing portion 30 to detect the flatness of the trash inside the trash receiving cavity 121. The gyroscope sensor can be disposed on the packaging strip.

[0085] Furthermore, the smart trash can further includes a position sensor, which is installed in the trash body 10 to detect the height of the trash inside the trash receiving cavity 121. The position sensor is a photoelectric sensor or an infrared sensor.

[0086] In this embodiment, the smart trash can also includes a main controller and a power supply. The power supply is used to provide electricity. Detection elements such as gravity sensors, position sensors, and gyroscope sensors are all connected to the main controller signal. The main controller is also electrically connected to the lifting drive part 410, the fan pump, the telescopic part, the picking part, and the sealing part 30.

[0087] Example 2

[0088] Different from the first embodiment, in this embodiment, the lifting portion is disposed in the garbage receiving chamber 121 .

[0089] Specifically, the lifting part is arranged inside the garbage receiving chamber 121, and the lifting drive part 410 drives the screw 430 to rotate and drives the slider 440 to move up and down inside the garbage receiving chamber 121, so that the picking part moves toward the garbage bag inside the garbage receiving chamber 121 and picks up the garbage bag.

[0090] It should be noted that the lifting portion is disposed in the garbage receiving chamber 121 , and the picking portion is also maintained inside the garbage receiving chamber 121 .

[0091] Example 3

[0092] This embodiment provides an operating method for a smart trash can, wherein the trash can is the smart trash can in Embodiment 1 or Embodiment 2, and the operating method for the smart trash can is used to implement bagging and sealing operations of the smart trash can.

[0093] like Figures 4 to 6 As shown, the operation method of the smart trash can includes:

[0094] After obtaining the back-sealing instruction, execute the garbage bag back-sealing operation;

[0095] The height information and weight information of the garbage are obtained, and when at least one of the height information and the weight information meets a preset condition, a garbage bag sealing operation is performed.

[0096] The method for obtaining the back cover instruction includes:

[0097] The actual weight M1 of the smart trash can is obtained through the gravity sensor; wherein the actual weight M1 is the weight in the current state, which can be the state of the smart trash can without a trash bag installed, or the state after the trash bag is installed.

[0098] The actual weight M1 is compared with the preset weight range; and only when the actual weight M1 meets the conditions of the preset weight range, the back cover instruction is sent.

[0099] The preset weight is a manually set weight within a range so that the next bottom sealing instruction can be sent as the number of garbage bags inside the garbage bag storage box 20 decreases. If the actual weight M1 is greater than or less than the preset weight range, no bottom sealing instruction is sent.

[0100] Furthermore, in the execution of the bottom sealing operation of the garbage bag, the sealing structure 310, i.e., the sealing strip, is controlled to move to shrink the bottom opening of the garbage bag. After the bottom opening of the garbage bag is shrunk, the heating element on the sealing strip close to the top of the barrel is started. At this time, the temperature of the heating element is the second heating temperature. The heating element seals the bottom opening of the garbage bag at the second heating temperature, thereby completing the bottom sealing operation. After the bottom sealing operation is completed, the sealing structure 310 is reset and the heating element stops heating.

[0101] The operation method of the smart trash can further includes a bag pulling operation after the bottom sealing operation of the trash bag is completed, wherein the bag pulling operation includes:

[0102] Obtaining a bag pulling instruction to enable the bag pulling assembly 40 to actuate and pick up the garbage bag;

[0103] After the bag pulling assembly 40 picks up the garbage bag, the bag pulling assembly 40 is activated and the fan pump is turned on at the same time, so that the garbage bag moves to the bottom of the garbage receiving chamber 121 of the smart garbage bin;

[0104] The bag pulling assembly 40 releases the garbage bag and resets the movement, turning off the blower pump.

[0105] Among them, the sealing structure 310 triggers the bag pulling instruction after being reset, and the lifting drive part 410 of the lifting part of the bag pulling assembly 40 drives the slider 440 through the screw 430 to drive the picking part to move toward the garbage bag. The air nozzle of the picking part is driven by the telescopic part to fit with the garbage bag after the bottom seal inside the garbage holding chamber 121, and is adsorbed under the action of air pressure; the adsorbed garbage bag follows the slider 440 to move downward under the drive of the picking part, so that the garbage bag moves downward along the inside of the garbage holding chamber 121; the fan pump is started to evacuate the inside of the garbage holding chamber 121, thereby assisting the garbage bag to enter the inside of the garbage holding chamber 121, and making the garbage bag holding chamber fit with the bottom surface of the garbage holding chamber 121.

[0106] It should be noted that, in the process of fitting the bottom of the garbage bag to the bottom surface of the accommodating cavity, the step of the puncturing part puncturing the garbage bag is also included.

[0107] In this embodiment, the operation method further includes setting a preset condition, wherein the preset condition is set to a preset garbage weight M2 and a preset garbage height H2, wherein the preset garbage weight M2 is greater than the initial weight M0 of the smart trash can;

[0108] After the bottom sealing operation of the garbage bag is completed, the actual weight M1 of the smart garbage can and the actual height H1 of the garbage inside the garbage receiving cavity 121 of the smart garbage can are obtained;

[0109] Compare the actual weight M1 with the preset garbage weight M2, and compare the actual height H1 with the preset garbage height H2;

[0110] If the actual weight M1 is greater than or equal to the preset garbage weight M2, and the actual height H1 is greater than or equal to the preset garbage height H2, the garbage bag sealing operation is performed.

[0111] Among them, the actual weight M1 is the total weight of the smart trash can and the garbage, and the actual height H1 is the height of the garbage inside the garbage containing cavity 121. After the height and weight meet the preset requirements, the sealing operation is started.

[0112] Furthermore, the garbage bag sealing operation includes the following steps:

[0113] The sealing strips of the sealing portion 30 are driven to move and shrink the bag opening of the garbage bag; wherein, the two sealing strips move laterally to shrink the bag opening of the garbage bag.

[0114] Start the heating element of the packaging strip to seal the opening of the garbage bag and cut the garbage bag; among them, start the heating element on the packaging strip close to the bottom of the barrel among the two packaging strips, and the heating element is at the first heating temperature, so as to squeeze the opening of the garbage bag through the heating element to achieve the sealing and cutting operations. After the sealing is completed, drive the two packaging strips to move and release the opening of the garbage bag.

[0115] Furthermore, under the heating at the first heating temperature, the plastic bag is heated and cut, and at the same time, at least part of the area at the bag opening is bonded together to achieve sealing.

[0116] After the garbage bag sealing operation is completed, the operation method of the smart garbage bin further includes a garbage compression operation after the garbage bag sealing operation is completed. The garbage compression operation includes:

[0117] The horizontal position information of the garbage is obtained to determine the target area for pushing; wherein, the horizontal position information of the garbage bag is detected by the gyroscope sensor on the sealing structure 310.

[0118] The garbage within the target pressing area is pressed. After obtaining the horizontal position information of the garbage bag, the bag pressing assembly 320 moves to the target pressing area of ​​the garbage bag and drives the pressing plate 324 downward through the pressing drive assembly, thereby pressing the garbage bag downward. The target pressing area is the relatively raised area of ​​the garbage bag.

[0119] Example 4

[0120] This embodiment differs from the third embodiment in that, in this embodiment, the operating method of the smart trash can further includes a method for obtaining a back cover instruction, and the method for obtaining a back cover instruction includes:

[0121] The initial weight M0 of the smart trash can when no trash bag is added is obtained; wherein, the initial weight M0 of the smart trash can when no trash bag is installed is obtained by a gravity sensor.

[0122] Obtain the actual weight M1 of the smart trash can; detect the real-time actual weight M1 of the smart trash can through a gravity sensor.

[0123] The actual weight M1 is compared with the initial weight M0. If the actual weight M1 is greater than the initial weight M0, a back-sealing instruction is issued. If the actual weight M1 is equal to the initial weight M0, no back-sealing instruction is issued and the actual weight M1 is continuously acquired. When the actual weight M1 is equal to the initial weight M0, no garbage bag is present in the garbage bag storage box 20.

[0124] Example 5

[0125] This embodiment is different from the third embodiment in that, in this embodiment, the operating method further includes setting a preset condition, and the preset condition is set to a preset garbage weight M2 and a preset garbage height H2, wherein the preset garbage weight M2 is greater than the initial weight M0 of the smart trash can.

[0126] After the bottom sealing operation of the garbage bag is completed, the actual weight M1 of the smart garbage bin and the actual height H1 of the garbage inside the garbage receiving cavity 121 of the smart garbage bin are obtained. The actual weight M1 and the actual height H1 are detected by a gravity sensor and a position sensor.

[0127] The actual weight M1 is compared with a preset trash weight M2, and the actual height H1 is compared with a preset trash height H2.

[0128] If the actual weight M1 is greater than or equal to the preset garbage weight M2 or the actual height H1 is greater than or equal to the preset garbage height H2, the garbage bag sealing operation is performed.

[0129] In this embodiment, the garbage bag sealing operation is performed when either the actual weight M1 is greater than or equal to the preset garbage weight M2 or the actual height H1 is greater than or equal to the preset garbage height H2.

[0130] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
