Description

Technical Field

[0001] The present invention relates to the technical field of trash cans, especially the technical field of intelligent trash cans. Background Art

[0002] Trash cans are essential daily necessities in daily life, and their application fields are extremely wide. For traditional trash cans, the upper part is an open mouth. Its advantage is that it is convenient for throwing garbage, but its disadvantages are that due to the visibility of the garbage, the aesthetics is insufficient, and the smell is easily dispersed. On this basis, there are intelligent trash cans. The upper end of the intelligent trash can is provided with a cover plate, and the upper cover of the trash can can be automatically opened and closed by electric drive, which is more convenient to use than traditional trash cans. Among them, Chinese Patent CN210285484U discloses a trash can cover and a trash can, including a fixed frame and a baffle provided on the fixed frame. A through hole is opened on the fixed frame, and a plurality of baffles for sealing the through hole are provided on the through hole, and each baffle is provided with a baffle connection part for connecting with the fixed frame. The fixed frame is also provided with a limit connection structure for limiting the bucket cover at the mouth of the trash can; this bucket cover can simply and reliably open and close the trash can mouth, so that the trash can mouth can achieve anti-odor sealing, prevent the breeding of mosquitoes and flies, and is also simple, beautiful, low-cost, and easy to use. At the same time, it is convenient for installation and disassembly and the connection is reliable. However, during the opening process of the small cover of this intelligent trash can, the small cover may not open or close in place or automatically close after partial opening due to various reasons, resulting in poor use effects and affecting the throwing of garbage. And nowadays, garbage classification and dry-wet separation are advocated. Most traditional intelligent trash cans only have one inner bucket inside, and dry-wet separation cannot be achieved. And because components such as motors, batteries, and control elements need to be provided inside the bucket cover of traditional intelligent trash cans, the opening of the trash can is mostly small. Even if two dry-wet inner buckets are provided in the traditional intelligent trash can, it is inconvenient to throw garbage due to the too small opening. Summary of the Invention

Specific embodiments

[0030] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present invention. Embodiment 1

[0031] Refer to Figure 1 、 Figure 2 And Figure 3, an intelligent trash can of the present invention that can use a sensor to detect whether the small lid is opened, includes an outer barrel body 1, a barrel lid main body 2 and a flip cover plate 3. The barrel lid main body 2 is detachably provided at the upper end of the outer barrel body 1. The opening of the barrel lid main body 2 is hinged to the flip cover plate 3. A cover plate opening detection device 6 is provided between the flip cover plate 3 and the barrel lid main body 2. The cover plate opening detection device 6 includes an infrared sensor 61 and an induction mechanism 62. The infrared sensor 61 is provided at the lower end of the flip cover plate 3, and the infrared sensor 61 is arranged towards the hinged end of the flip cover plate 3 and the barrel lid main body 2. An induction mechanism 62 that can cooperate with the infrared sensor 61 is provided at the lower end of the flip cover plate 3. The cover plate opening detection device 6 can monitor the position of the barrel lid when the trash can cover plate is opened, ensure that the barrel lid is opened in place, and avoid the flip cover plate 3 not being opened in place and affecting garbage throwing.

[0032] Refer to Figure 3 , the induction mechanism 62 includes an induction reflector 621 and a reflector hinge arm 622. An induction reflector 621 that can cooperate with it is provided at the emission end of the infrared sensor 61. One end of the induction reflector 621 is hingedly connected to the lower end face of the flip cover plate 3, and the other end is hingedly connected to the reflector hinge arm 622. The other end of the reflector hinge arm 622 is hingedly connected to the inner wall of the barrel lid main body 2. The infrared sensor 61 is a sensor with a relatively short monitoring effective distance. The cover plate opening detection device 6 judges whether the flip cover plate 3 is fully opened by receiving the reflected signal of the induction reflector 621. When the flip cover plate 3 is closed, the induction reflector 621 faces downwards. At this time, the induction reflector 621 just blocks the infrared sensor 61, and the signal emitted by the emission end of the infrared sensor 61 will be blocked and reflected back by the receiving induction reflector 63 and received by its own receiving end. Thereby judging that the small lid is in the closed state. When the flip cover plate 3 is opened, the induction reflector 621 and the reflector hinge arm 622 cooperate to start rotating. Only when the flip cover plate 3 is fully opened in place, the induction reflector 621 no longer blocks the emission end of the infrared sensor 61, and no returned signal is received by the sensor. Thereby judging that the small lid is opened in place. Any failure to open in place will block the infrared signal, and the returned signal will surely be received by the sensor, thereby judging that the flip cover plate 3 is not fully opened in place.

[0033] Refer to Figure 2 , Figure 3 , a drive mechanism installation cavity 22 is provided in the barrel lid main body 2. A flip cover drive mechanism 4 that can drive the flip cover plate 3 to open and close is provided in the drive mechanism installation cavity 22. The setting of the flip cover drive mechanism 4 realizes automatic opening of the lid, making it more convenient to use.

[0034] Refer to Figure 3, the flip cover driving mechanism 4 includes a flip cover driving motor 41, a motor connecting rod 42, and a flip cover connecting rod 43. The flip cover driving motor 41 is fixedly arranged in the driving mechanism installation cavity 22. The motor connecting rod 42 is arranged on the rotating shaft of the flip cover driving motor 41. The end of the motor connecting rod 42 is hinged to the flip cover connecting rod 43. The other end of the flip cover connecting rod 43 is hingedly connected to the lower end surface of the flip cover plate 3. The flip cover driving motor 41 controls the opening and closing of the flip cover plate 3 through the crank connecting rod principle, which is more labor-saving and has a simple and reasonable structure.

[0035] Refer to Figure 3 , a fixed cover plate 5 is provided at the upper end of the driving mechanism installation cavity 22. It is provided to protect the flip cover driving motor 41 and the bucket cover body 2 and facilitate installation and disassembly. Embodiment 2

[0036] Refer to Figures 4 - 8 , on the basis of Embodiment 1, a first inner bucket body 7 and a second inner bucket body 8 are arranged inside the outer bucket body 1.

[0037] Refer to Figure 4 , a bucket body switching device 9 for driving their rotation is provided at the lower ends of the first inner bucket body 7 and the second inner bucket body 8. The first inner bucket body 7 and the second inner bucket body 8 can be driven to rotate through the bucket body switching device 9 so that one of the inner bucket bodies is aligned with the garbage inlet for easy garbage throwing.

[0038] Refer to Figure 7 , the bucket body switching device 9 includes a bucket body switching reduction motor 91, a turntable 92, and an inner bucket body fixed tray 93. A turntable 92 that can cooperate with the first inner bucket body 7 and the second inner bucket body 8 is horizontally arranged at the inner bottom of the outer bucket body 1. The bucket body switching reduction motor 91 for driving its rotation is provided at the lower end of the turntable 92. The first inner bucket body 7 and the second inner bucket body 8 are respectively arranged on both sides of the upper end of the turntable 92. Inner bucket body fixed trays 93 that can cooperate with the first inner bucket body 7 and the second inner bucket body 8 are symmetrically arranged on both sides of the upper end of the turntable 92 respectively. By driving the turntable 92 to rotate through the bucket body switching reduction motor 91, one of the first inner bucket body 7 and the second inner bucket body 8 is aligned with the garbage inlet for easy garbage throwing.

[0039] Refer to Figure 7 , an annular boss 12 that can cooperate with the turntable 92 is provided on the inner wall of the outer bucket body 1. A plain bearing 95 is provided between the annular boss 12 and the turntable 92. The provision of the annular boss 12 and the plain bearing 95 improves the load-bearing performance of the turntable 92, makes the turntable rotate more stably, and improves the service life.

[0040] Refer to Figure 8, on both sides of the upper end of the bucket cover main body 2, a first proximity sensor 17 and a second proximity sensor 18 are symmetrically arranged respectively. The first proximity sensor 17 and the second proximity sensor 18 are connected to the bucket body switching device 9 for control. The first proximity sensor 17 and the second proximity sensor 18 correspond to the first inner bucket body 7 and the second inner bucket body 8 respectively. Specifically, when in use, when one of the sensors is blocked, the control device receives the signal, controls the flip cover driving mechanism 4 to open the flip cover plate 3, and at the same time controls the bucket body switching device 9 to rotate, aligning the inner bucket body corresponding to the sensor with the garbage inlet, which is convenient for garbage throwing. The control of the trash can is more convenient, with contactless control, and the dry and wet trash cans can be freely rotated and switched.

[0041] See Figure 7 , at the bottom of the outer bucket body 1, a battery installation cavity 13 is provided. A number of batteries 131 are provided in the battery installation cavity 13. The battery installation cavity 13 is electrically connected to the flip cover driving mechanism 4, the cover opening detection device 6, and the bucket body switching device 9. A lower sealing cover plate 14 is detachably provided at the lower opening of the battery installation cavity 13. Using battery power supply enables the trash can to have its own power supply, and the use range is not restricted, without the need for external power supply access.

[0042] See Figure 4 , a first wire groove 15 is vertically provided on the inner wall of the outer bucket body 1. The lower end of the first wire groove 15 is communicated with the battery installation cavity 13. A second wire groove 16 that can cooperate with the first wire groove 15 is vertically provided on the inner wall of the bucket cover main body 2. A male connection head 151 is provided at the upper end of the first wire groove 15. A female connection head 161 that can cooperate with the male connection head 151 is provided at the lower end of the second wire groove 16. The male connection head 151 and the female connection head 161 are detachably electrically connected. Using the wire grooves to cooperate with each other to protect the circuit and prevent the circuit from being damaged, and connecting the two sides of the wire grooves through the cooperation of the male connection head 151 and the female connection head 161 is convenient for the disassembly of the bucket cover main body 2 and convenient for maintenance.

[0043] See Figure 4 , Figure 5 , an openable side door 19 is provided on the side wall of the outer bucket body 1. Adding the side door 19 makes it more convenient to replace the garbage bag of the inner bucket body. There is no need to lift the bucket cover main body 2, just open the side door 19.

[0044] See Figure 4 , a number of ultraviolet germicidal lamps 111 are provided in the bucket cover main body 2. Setting the ultraviolet germicidal lamps 111 can sterilize the garbage in the bucket and the inner wall of the trash can, making it safer and more hygienic.

[0045] See Figure 8 , a control single-chip microcomputer 10 is provided in the bucket cover main body 2. A touch control panel 11 that can cooperate with it is provided at the upper end of the fixed control single-chip microcomputer 10. The control single-chip microcomputer 10 is used to control the operation of each mechanism to achieve automatic operation.

[0046] Working process of the present invention:

[0047] In the working process of an intelligent trash can of the present invention that can use sensors to detect whether the small lid is opened, the first inner barrel 7 and the second inner barrel 8 are respectively used to hold dry and wet garbage. The first proximity sensor 17 and the second proximity sensor 18 respectively correspond to the first inner barrel 7 and the second inner barrel 8, that is, they respectively correspond to the dry and wet trash cans. When one of the sensors is blocked, the control single-chip microcomputer 10 receives the signal and controls the flip cover driving mechanism 4 to open the flip cover 3. The cover opening detection device 6 monitors the position of the flip cover 3 until the flip cover 3 is fully opened. When the flip cover 3 is opened, the induction reflector 621 and the reflector hinge arm 622 cooperate to start rotating. Only when the flip cover 3 is fully opened, the induction reflector 621 no longer blocks the transmitting end of the infrared sensor 61, and no returned signal is received by the sensor, thereby determining that the small lid is opened in place, transmitting the signal to the control single-chip microcomputer 10, and the flip cover driving mechanism 4 stops. At the same time, the control single-chip microcomputer 10 controls the barrel switching device 9 to rotate, aligning the inner barrel corresponding to the sensor with the garbage inlet to facilitate garbage throwing. After a certain preset time, the control single-chip microcomputer 10 automatically controls the flip cover driving mechanism 4 to close the flip cover 3.
