Description

Technical Field

[0001] This technical solution relates to the field of trash can technology, specifically a trash can with a suction function. Background Technology

[0002] Trash cans are special containers used to collect and temporarily store waste. They are usually made of plastic, metal or composite materials. When using them, a plastic bag must be placed inside, and they are equipped with a sealed odor-proof design. They are usually open, foot-operated or sensor-operated.

[0003] Existing smart trash cans, which can automatically open and close their lids via sensors, typically require batteries and sensors. To make trash bag placement easier, Chinese patent CN219057360U discloses a suction mechanism for a smart trash can. The can body includes a bottom and side walls. The side walls are arranged circumferentially around the bottom of the can, forming a trash disposal area. A portion of the side walls is concave towards the trash disposal area, creating a mounting groove on the outer side of the side walls for installing the suction device of the trash can. The concave portion of the side walls forms the bottom of the mounting groove, a first groove wall, and a second groove wall opposite to each other on both sides of the bottom of the groove. The bottom of the groove also has a suction port, which connects to the mounting groove and the trash disposal area.

[0004] The batteries and sensors in the aforementioned trash cans are basically installed in the lid, which is hinged to the body. The motor needs to drive the lid at the hinge. The suction mechanism is usually installed in the body, sharing the same motor or circuit system with the lid's automatic sensor switch system. They are connected by wires. When users need to remove the lid to lay out a trash bag, they need to handle the wires connecting the suction mechanism and the motor, which is inconvenient and needs improvement. Summary of the Invention

[0005] This technical solution aims to improve the problem of cumbersome garbage bag replacement operations caused by the shared motor / circuit between the suction mechanism and the lid opening mechanism, by providing a garbage bin with a suction function.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A trash can with a suction function includes a can body and a can lid. The can body has a can cavity. The can lid is detachably fitted onto the top of the can body. The can lid is hinged to an inner lid. The can lid is equipped with a control mechanism and a lid-opening mechanism. The can body is provided with a suction mechanism. The control mechanism, the lid-opening mechanism, and the suction mechanism are electrically connected.

[0008] The suction mechanism includes a contact connector, which is movably mounted on the barrel body. The barrel lid has a contact terminal corresponding to the contact connector. When the barrel lid is closed on the barrel body, the contact connector and the corresponding contact terminal abut against each other to establish a conductive path. The control mechanism can control the suction mechanism to work for a set time. When the barrel lid is separated from the barrel body, the contact connector and the contact terminal lose contact, the control mechanism disconnects from the suction mechanism, and the suction mechanism enters a non-working state.

[0009] Through the above technical solution, when a trash can with a suction function is in normal use, the user lifts the lid to separate the contact terminal from the contact connector, replaces the trash bag inside the can cavity, and then puts the lid back on top of the can. At this time, the contact terminal and the contact connector align and make contact with the conductive circuit. The control mechanism drives the suction mechanism to start running. Through the negative pressure effect, the trash bag inside the can cavity is automatically adsorbed and unfolded. Furthermore, a preset delay shutdown function is provided, and the suction mechanism automatically stops working after running for a period of time. Through the contact linkage between the contact connector and the contact terminal, the power supply circuit of the suction mechanism is forcibly cut off by physical disconnection, avoiding the redundancy of step-by-step power cut-off and lid opening disconnection operations required by the control mechanism to simultaneously control the suction mechanism and the lid opening mechanism. The suction function is synchronously controlled according to the lid status, simplifying the user's operation process and making it more convenient to use.

[0010] Preferably, the suction mechanism includes the contact connector, the fan, and the wire electrically connected between the contact connector and the fan. A first ventilation opening is provided along the side wall at the lower part of the barrel, and the fan is installed outside the first ventilation opening.

[0011] The contact connector includes a switch body, an elastic element, and an abutment post. The switch body has an electrical contact for wire connection. The switch body has a receiving groove on the side away from the electrical contact. The abutment post is movably disposed in the receiving groove, and the elastic element is installed in the receiving groove. One end of the elastic element abuts against the bottom of the receiving groove, and the other end abuts against the abutment post. Its elasticity causes the abutment post to tend to push out away from the receiving groove.

[0012] Through the above technical solution, the abutment post in the contact connector normally extends outward under the elastic force of the elastic element. When the lid is closed, the contact terminal presses down on the abutment post, compressing the elastic element and causing the abutment post to retract into the receiving groove. The abutment post conducts the circuit, enabling the fan to be powered on and start, activating the suction function and ensuring stable operation of the fan at the first ventilation opening to achieve air circulation or negative pressure sealing. When the lid is lifted, the trigger screw is lifted along with the lid and disengages from the abutment post to forcibly cut off the power. The elastic element rebounds and pushes the abutment post to reset. The adaptive compensation design of the elastic element can reduce the impact of component assembly errors. Through the mechanical cooperation between the elastic element and the contact terminal, the contact pressure is ensured to be stable, the on / off state is accurately controlled, the delayed response of power on when the lid is closed and power off when it is opened is reduced, and the assembly structure of the switch assembly is simplified.

[0013] Preferably, the side wall of the barrel has an installation cavity, the installation cavity is fitted with an installation plate, the first vent connects the barrel cavity and the installation cavity, the installation plate has a second vent through the first vent, the suction mechanism is placed in the installation cavity, and the fan is located between the first vent and the second vent.

[0014] Through the above technical solution, the mounting cavity is connected to the barrel cavity through the first vent. The second vent on the mounting plate corresponds to the first vent to form a ventilation path. The suction mechanism is embedded in the mounting cavity. The fan is precisely positioned between the first and second vents, drawing air from the barrel cavity into the mounting cavity through the first vent. After passing through the fan, the air is directionally discharged from the second vent, forming a highly efficient unidirectional airflow and improving the stability of the airflow path. The wires are neatly arranged in the mounting cavity, and a path for providing circuitry to the fan is established by the contact connectors and wire connections. The mounting cavity, through the mounting plate, effectively isolates fan noise and prevents foreign objects from entering, facilitating maintenance and cleaning and improving protection.

[0015] Preferably, the barrel body is provided with a cable guide block that extends into the mounting cavity, and the cable guide block has a cable guide groove for clamping and positioning the wire.

[0016] Through the above technical solution, the cable trays opened in the cable tray precisely fix the wires in a snap-fit ​​manner, constrain the direction of the wires, and prevent the wires from getting tangled or loose; reduce the risk of short circuits, while simplifying the assembly and disassembly process for later maintenance, and improving the reliability of the electrical system.

[0017] Preferably, a frame is installed around the opening of the bucket cavity at the upper end of the bucket body, and the bucket lid has a covering cavity corresponding to the frame. The upper part of the frame is embedded in the covering cavity, and the frame is used for the folding and fitting of the garbage bag.

[0018] A triggering mechanism is also connected in series in the circuit path between the control mechanism and the suction mechanism. The triggering mechanism includes an abutment protrusion on the mouth frame and a spring switch on the bucket lid. The spring switch is provided corresponding to the abutment protrusion.

[0019] When the abutting protrusion abuts against the spring switch to form an electrical connection, the contact joint and the contact terminal are in a conductive state. When the abutting protrusion separates from the spring switch, the circuit between the contact joint and the contact terminal is broken.

[0020] Through the above technical solution, the folded edge of the garbage bag can be unfolded and fitted snugly onto the outer wall of the opening frame. When the lid is closed, its covering cavity completely fits the upper part of the opening frame, and the lid fits onto the outside of the opening frame, forming a tight nested structure. At the same time, the abutting protrusion on the side wall of the opening frame presses tightly against the spring switch on the inner wall of the lid, triggering the spring switch to close and forming a secondary conduction node. At this time, the primary conduction path formed by the contact joint and the contact terminal is connected in series with the secondary conduction path of the spring switch, and the suction mechanism circuit is fully connected and starts working. When the lid is opened again, the covering cavity separates from the opening frame, causing the abutting protrusion to disengage from the spring switch, and the spring switch returns to its original position. Even if there is still a brief contact between the contact joint and the contact terminal, the two-stage series circuit is still forcibly cut off, ensuring that the suction mechanism is completely de-energized, avoiding false triggering or poor contact caused by lid misalignment, reducing accidental start-up caused by loose contact or false triggering, and improving system reliability.

[0021] Preferably, the mouth frame has a protruding boss, the boss corresponding to the contact connector for the contact connector to pass through the protruding through hole, the bucket lid has a positioning part corresponding to the boss, the inner side of the positioning part has a positioning groove, the positioning groove has a connecting hole, and the contact terminal is connected in the connecting hole.

[0022] When the boss portion is fitted into the positioning groove, the contact terminals make contact with the contact connectors one by one.

[0023] The above technical solution ensures the alignment accuracy of the contact connector and improves the reliability of the response by the embedded fit between the boss and the positioning groove.

[0024] Preferably, the control mechanism includes a sensor switch, a battery, and a circuit board. The bucket lid has a battery slot, and a battery cover is detachably installed in the battery slot. The battery is installed in the battery slot and connected to the circuit board. The circuit board is connected to the sensor switch, so that the sensor switch controls the operation of the lid opening mechanism through the circuit board. The battery is used to supply power to the lid opening mechanism and the suction mechanism.

[0025] Through the above technical solution, the battery slot at the top of the lid houses a removable battery, which is sealed and protected by the battery cover. The battery is connected to the circuit board via circuit wires to form an independent power supply circuit. The circuit board integrates a sensor switch signal processing function, which can control the start and stop of the lid opening mechanism and the suction mechanism. The sensor switch monitors the delivery port area in real time. When it detects a user approaching or performing a gesture, it immediately triggers a signal to drive the lid opening mechanism to start and open the inner lid. If there is no continuous action signal within a set delay, the sensor switch automatically drives the inner lid to close, avoiding contact contamination from manual operation. This non-intrusive triggering reduces energy consumption and improves hygiene and operational smoothness.

[0026] Preferably, the bucket lid is equipped with an electric switch that can switch between an open state and a closed state to control the opening and closing of the connection between the battery and the motor.

[0027] Through the above technical solution, the manually toggle switch can be operated. When the switch is swung to the closed state, the internal contacts of the switch separate, cutting off the power supply link of the battery and causing the cover opening mechanism and the suction mechanism to be powered off simultaneously. When switched to the open state, the switch contacts close to restore the power supply circuit, and the system responds again. At this time, the cover opening or suction action can be commanded to be executed, providing users with the authority to actively cut off the power. During long-term idle or maintenance, the power can be manually cut off to avoid battery damage and extend battery life.

[0028] Preferably, the opening mechanism includes a motor and a transmission assembly. The transmission assembly includes a transmission seat disposed on the lid and a transmission swing member disposed on the transmission seat. The transmission seat has a fixed cavity, and the swing member swings within the fixed cavity. The transmission swing member is connected to the inner lid, and the motor drives the transmission swing member to open the inner lid.

[0029] With the above technical solution, when the motor starts, the drive transmission swinging component swings around the axis in the fixed cavity of the transmission seat, causing the inner cover hinged to it to rotate around the fulcrum of the bucket lid and open; the inner wall of the fixed cavity physically limits the swing trajectory of the transmission swinging component, ensuring that the opening and closing angle of the inner cover is stable and controllable and avoiding overload impact, thereby realizing the opening of the inner cover.

[0030] Preferably, the transmission swing component includes a connecting section, a guide arc section, and a rotating shaft section. The guide arc section is connected between the connecting section and the rotating shaft section. The rotating shaft section has a transmission tooth section located on the side of the rotating shaft section near the motor. The output end of the motor is provided with a transmission gear, which meshes with the transmission tooth section. The connecting section is connected to the inner cover. The motor drives the transmission gear to rotate. The transmission tooth section cooperates with the transmission gear to realize the reciprocating swing of the transmission swing component.

[0031] Through the above technical solution, the transmission gear of the motor meshes with the transmission tooth segment of the shaft section of the transmission swing component. When the motor drives the transmission gear to rotate, the meshing action causes the shaft section to rotate around the axis of the fixed cavity. The guide arc segment of the transmission swing component is limited and guided by the cavity wall in the fixed cavity, which converts the rotation of the shaft section into the linear reciprocating oscillation of the connecting segment, thereby pulling the inner cover to open and close smoothly around the hinge point. When opening, the motor reverses, the transmission gear pushes the transmission tooth segment to rotate in the opposite direction, and the guide arc segment slides along the cavity wall to the limit position on the other side, causing the inner cover to fully unfold. The unidirectional rotation of the motor is precisely converted into the bidirectional controllable movement of the swing component, improving the stability of the opening and closing angle and speed of the inner cover.

[0032] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0033] 1. This technical solution uses the contact linkage between the contact connector and the contact terminal of the lid to automatically activate the suction mechanism when the lid and the body are installed. It uses negative pressure to adsorb and unfold the garbage bag, and has a preset delay shutdown function to automatically cut off the power after the fan runs. This eliminates the need for step-by-step operation or disconnection of wires to cut off the power, simplifying the user's operation steps and avoiding redundant motor operation, thus improving convenience.

[0043] Specific implementation methods

[0044] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. Example:

[0045] See Figure 1 and Figure 2 A trash can with a suction function includes a can body 1 and a can lid 2. The can body 1 has a can cavity 3, which is shaped to correspond to the internal shape of the can body 1 and serves as a space for holding trash bags and trash. A mouth frame 17 is installed around the opening of the can cavity 3 at the upper end of the can body 1. The mouth frame 17 is installed on the can body 1 by a plug-in structure. In this embodiment, the upper part of the mouth frame 17 is smaller than the lower part, so that the lower part of the mouth frame 17 is adapted to the opening of the can cavity 3. The lower end of the can lid 2 has a covering cavity 33 for the mouth frame 17 to be inserted. The upper part of the mouth frame 17 can be inserted into the covering cavity 33 of the can lid 2. The trash bag is folded over and fitted onto the mouth frame 17. The can lid 2 can be placed against the mouth frame 17 so that it can be detachably closed on the top of the can body 1 to open the can cavity 3.

[0046] See Figure 3 and Figure 5The barrel body 1 is equipped with a suction mechanism 7 and a mounting cavity 9 located on the rear side wall of the barrel body 1. The suction mechanism 7 is installed in the mounting cavity 9 and includes a contact connector 71, a fan 72, and a wire 73. The fan 72 is installed in the lower part of the mounting cavity 9 and typically has fan blades with multiple blades. The fan blades are driven to rotate to drive airflow. The barrel body 1 is equipped with a first vent 10 located in the lower part of the barrel body 1 and penetrating the side wall of the barrel body 1, so that the barrel cavity 3 communicates with the mounting cavity 9. The first vent 10 consists of several ventilation holes for conduction. The airflow path between the barrel cavity 3 and the mounting cavity 9; the mounting cavity 9 is equipped with a suitable mounting plate 11, which is connected to the barrel body 1 by bolts, so that the mounting cavity 9 is covered to protect the internal structure. The mounting plate 11 is provided with a second vent 12 aligned with the first vent 10. The second vent 12 is composed of several ventilation holes and is used to guide the airflow path between the mounting cavity 9 and the outside; the fan 72 is located between the first vent 10 and the second vent 12. The first vent 10, the fan 72 and the second vent 12 work together to establish a complete airflow path.

[0047] The barrel 1 is provided with a cable tray 31, which extends into the mounting cavity 9 and is integrally connected to the inner wall of the mounting cavity 9. The end of the cable tray 31 away from the barrel 1 is provided with a cable tray 32. The side of the cable tray 32 away from the barrel 1 is open. The wire 73 can be embedded in the cable tray 32 for positioning. One end of the wire 73 is connected to the fan 72 and the other end is connected to the contact connector 71.

[0048] See Figure 2 and Figure 4 At least two contact connectors 71 are arranged side by side. The two contact connectors 71 are used to establish a positive connection and a negative connection, respectively. The barrel 1 has a boss 20, which is located on the rear side of the barrel 1 and protrudes from the top end face of the barrel 1. Each contact connector 71 includes a switch body 711, an elastic element 712, and an abutment post 713. The boss 20 has two through holes 21. The two switch bodies 711 are fixed in the corresponding two through holes 21 by snap-fit ​​or adhesive. Each switch body 711 has a receiving groove 13 on the upper end face away from the mounting cavity 9. The switch body 711 also has an electrical contact. 14, located on the side of the switch contact away from the opening of the receiving groove 13, with two wires 73 and two electrical contacts 14 wound together in a corresponding manner for electrical connection; the elastic element 712 is adapted to the size of the receiving groove 13, the elastic element 712 is embedded in the receiving groove 13, the abutment post 713 is movably installed in the receiving groove 13, its lower end is embedded in the receiving groove 13, and is restricted from detaching from the receiving groove 13 by providing a protruding structure, one end of the elastic element 712 abuts against the bottom of the receiving groove 13, and the other end abuts against the end face corresponding to the embedded end of the abutment post 713, the elastic force makes the abutment post 713 tend to push out away from the receiving groove 13.

[0049] See Figure 3 , Figure 4 and Figure 6 The bucket lid 2 is provided with a positioning part 22, which is located below the bucket lid 2 and is positioned corresponding to the boss part 20. The positioning part 22 has a positioning groove 23 formed on its inner side. The size and shape of the positioning groove 23 are adapted to the boss part 20. The bottom of the positioning groove 23 has two connecting holes 15. The positions of the two connecting holes 15 are aligned with the two contact joints 71 located on the bucket body 1.

[0050] The lid 2 is provided with contact terminals 8, which are preferably conductive metal screws. There are two contact terminals 8. Since the contact terminals 8 are metal screws with external thread structure, the connecting hole 15 can be arranged with internal thread structure along the inner wall. The two contact terminals 8 are threadedly connected to the two connecting holes 15 one-to-one, so that when the positioning groove 23 is fitted with the boss part 20, the two contact terminals 8 are aligned with the two contact joints 71 to establish a complete circuit so that the current can pass through after being energized.

[0051] See Figure 6 , Figure 7 The lid 2 also includes a control mechanism 5, which comprises a sensor switch 51, a battery component 52, and a circuit board 53. At least one battery component 52 is provided, preferably a rechargeable battery. The lid 2 has a battery slot 27, which is located on the lower surface of the lid 2. The battery slot 27 has different sizes and specifications to accommodate different numbers of battery components 52. A charging port is provided on the side wall of the lid 2, through which a charging cable can be connected to charge the battery component 52. The circuit board 53 is installed inside the lid 2. Its position is above the battery compartment 27, and the circuit board 53 is connected to the battery component 52; the induction switch 51 is installed on the top of the bucket lid 2, which is above the circuit board 53. The bucket lid 2 is equipped with an opening mechanism 6. The induction switch 51 is used to control the operation of the opening mechanism 6. The induction switch 51 monitors the delivery port area in real time. When it detects that the user is close or performs a gesture operation, it immediately triggers a signal to conduct the opening mechanism 6 to start opening the bucket cavity 3. If the induction switch 51 does not have a continuous action signal within the set delay, the opening mechanism 6 will automatically start to close the bucket cavity 3.

[0052] The lid 2 is equipped with an electric switch 29, which is swung and installed on the lower end face of the lid 2. The electric switch 29 can switch between the open and closed states. When the electric switch 29 swings to the closed state, the internal contacts of the switch separate, cutting off the power supply link of the battery 52, so that the lid opening mechanism 6 and the suction mechanism 7 are simultaneously de-energized. When switching to the open state, the contacts of the electric switch 29 close to restore the power supply circuit, and the system responds again. At this time, the lid opening or suction action can be commanded.

[0053] See Figure 8The bucket lid 2 has an inner lid 4, which is hinged to the top of the bucket lid 2. The bucket lid 2 has a dispensing port communicating with the bucket cavity 3. The inner lid 4 rotates around the hinge axis to open or close the dispensing port. The lid opening mechanism 6 is used to drive the inner lid 4 to open or close. The lid opening mechanism 6 includes a motor 61 and a transmission assembly 62. The battery 52 is connected to the motor 61 for power supply. The transmission assembly 62 includes a transmission seat 621 and a transmission swing member 622. The transmission seat 621 is installed inside the bucket lid 2 and is located on one side of the output end of the motor 61. It has a fixed cavity 25, which corresponds to the front side of the transmission seat 621 and The upper side is open, and the transmission component 622 is movably installed in the fixed cavity 25. The transmission component 622 includes a connecting section 6221, a guide arc section 6222, and a rotating shaft section 6223. The output end of the motor 61 is provided with a transmission gear 16. The end of the rotating shaft section 6223 corresponding to the side of the transmission gear 16 is provided with a transmission tooth section 26, which is adapted to and meshes with the transmission gear 16. The guide arc section 6222 connects the connecting section 6221 and the rotating shaft section 6223. It has an arc surface, so that the overall shape of the guide arc section 6222 is arc-shaped. The connecting section 6221 is fixedly connected to the inner cover 4 by bolts.

[0054] The transmission gear 16 is driven to rotate by the motor 61. When the motor 61 rotates forward, the transmission gear 16 drives the rotating shaft 6223 to rotate synchronously through the meshing structure with the transmission gear segment 26. The rotation of the rotating shaft segment 6223 is converted into the reciprocating oscillation of the connecting segment 6221, which in turn drives the inner cover 4 to close. When the motor 61 rotates in reverse, the transmission gear 16 rotates in the opposite direction, and the guide arc segment 6222 slides along the cavity wall to the limit position on the other side, which drives the inner cover 4 to fully unfold, thus accurately converting the unidirectional rotation of the motor 61 into the bidirectional controllable movement of the ornament.

[0055] See Figure 2 , Figure 3 as well as Figure 6A trigger mechanism 18 is provided on the branch circuit between the motor 61 and the suction mechanism 7. This trigger mechanism includes an abutment protrusion 181 and a spring switch 182. The abutment protrusion 181 protrudes from the upper end of the frame 17, and the spring switch 182 is correspondingly located on the lower end face of the lid 2 and is movably connected to the lid 2. When the lid 2 is closed, the abutment protrusion 181 presses against the spring switch 182, establishing a circuit and opening the first switch. Since the first switch and the contact connector 71 are connected in series, the contact connector 71 and the contact terminal 8 serve as the second... When the switch is activated, the contact connector 71 and the contact terminal 8 can be triggered to conduct the circuit, and the first switch and the second switch are simultaneously connected. When the lid 2 is opened again, the abutment protrusion 181 disengages from the spring switch 182, the spring switch 182 returns to its original position, and the first switch is disconnected. Even if there is still a brief contact between the contact connector 71 and the contact terminal 8, the two-stage series circuit is still forcibly cut off, ensuring that the suction mechanism 7 is completely de-energized, avoiding false triggering or poor contact caused by the offset of the lid 2, reducing accidental start-up caused by loose contact or false contact, and improving system reliability.

[0056] The specific work process of this plan is as follows:

[0057] This technical solution separates the lid 2 from the body 1, allowing the contact terminal 8 to separate from the contact connector 71. After replacing the garbage bag inside the bin cavity 3, the lid 2 is repositioned on top of the body 1. At this point, the contact terminal 8 and the contact connector 71 align and connect to the conductive circuit. The motor 61 drives the suction mechanism 7 to start running. Through the negative pressure effect, the garbage bag inside the bin cavity 3 is automatically adsorbed and unfolded. Furthermore, a preset delay shut-off function is implemented, and the suction mechanism 7 automatically stops working after running for a period of time. This avoids the redundancy of needing to disconnect power and open the lid and disconnect wires step by step due to the motor 61 simultaneously controlling the suction and lid mechanisms. Through the contact linkage between the contact connector 71 and the contact terminal 8 of the lid 2, the suction function is synchronously controlled according to the lid status, simplifying the user's operation process and making it more convenient to use.
