[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] In the description of the present invention, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference Figure 1 and Figure 2 The public trash can provided in this embodiment includes a base 10, a barrel body 20 and a trash collection box 90, wherein the barrel body 20 is rotatably installed on the base 10 so that the barrel body 20 can rotate around a vertical axis, and the side wall of the barrel body 20 is provided with an installation port and a trash delivery port 21 opposite to the installation port. The trash collection box 90 is loaded into the barrel body 20 through the installation port, and the trash is dropped into the trash collection box 90 in the barrel body 20 through the trash delivery port 21.

[0033] In specific use, taking the airport as an example, the public trash cans are placed near the wall or corner of the airport. When it is necessary to place the trash storage box 90 in the barrel body 20 or take out the trash storage box 90 from the barrel body 20, the barrel body 20 is rotated so that the installation port is set opposite to the wall or corner to facilitate the operation of the staff; after the trash storage box 90 is installed in the barrel body 20, the barrel body 20 is rotated again so that the installation port faces the wall or corner, and the trash delivery port 21 is set outward at this time to facilitate the delivery of trash. This setting can hide the installation port, so that only the trash delivery port 21 of the public trash can is exposed, ensuring the beauty and coordination of the airport; in addition, when the installation port is in an open state, the wall or corner will also prevent the trash storage box 90 from escaping from the installation port, effectively avoiding the accidental spillage of the trash in the trash storage box 90, and ensuring the performance of the public trash can.

[0034] It is worth noting that in this embodiment, the barrel body 20 is a cylindrical structure, the garbage collection box 90 is preferably an upper open structure, the garbage inlet 21 is arranged near the upper end of the barrel body 20, and the barrel body 20 is provided with a channel arranged obliquely downward at the garbage inlet 21. The channel is located in the inner cavity of the barrel body 20 and docks with the upper end opening of the garbage collection box 90. When the garbage is put into the garbage inlet 21, it can be directly introduced into the garbage collection box 90 under the guidance of the channel, effectively avoiding the garbage from entering the gap between the garbage collection box 90 and the barrel body 20, ensuring the cleanliness of the inner cavity of the barrel body 20. Finally, in this embodiment, the barrel body 20 and the base 10 are preferably connected in rotation through a bearing. Specifically, a central axis is extended upward from the upper center position of the base 10, and a blind hole is correspondingly provided at the lower center position of the barrel body 20. The inner ring of the bearing is interference fit with the central axis, and the outer ring is interference fit with the blind hole.

[0035] Specifically, this embodiment also provides the following detailed introduction to the specific structure of the public trash can.

[0036] Reference Figure 4 In this embodiment, the barrel body 20 is an upper open structure, and the public trash can also includes a cover body 30, which is installed on the barrel body 20 and is used to close the upper end opening of the barrel body 20. The cover body 30 is installed with a sensor 50, which faces the opening of the garbage storage box 90 and is used to detect the amount of garbage in the garbage storage box 90.

[0037] Specifically, a limiting portion for limiting the position of the garbage storage box 90 is correspondingly provided in the barrel body 20 to ensure the relative fixation of the garbage storage box 90 and the barrel body 20. The sensor 50 is installed on the lower end surface of the cover body 30 and faces the upper end opening of the garbage storage box 90. At this time, the sensor 50 is preferably an infrared sensor. The infrared sensor can detect the height of the garbage in the garbage storage box 90 in real time. When the garbage is about to overflow, the infrared sensor senses and feeds back the corresponding signal to the controller, and the controller feeds back the information to the staff, so that the staff can complete the garbage dumping and cleaning of the garbage storage box 90 in time.

[0038] This arrangement effectively prevents passengers from continuing to put in garbage when the garbage storage box 90 is full, causing garbage to pile up outside the public garbage bin, thereby effectively ensuring a clean and tidy airport environment.

[0039] It is worth noting that the connection relationship and control relationship between the controller, the sensor 50 and the subsequent overflow warning light 60 in this embodiment are prior arts well known to those skilled in the art and will not be described in detail here.

[0040] Please continue to refer to Figure 4In this embodiment, the public trash can further includes an overflow indicator light 60, which is mounted on the cover 30 and is used to indicate whether the trash storage box 90 is full of trash.

[0041] Preferably, when the garbage storage box 90 is not full of garbage, the overflow warning light 60 emits green light. When the garbage storage box 90 is about to overflow, the infrared sensor feeds back a signal to the controller, and the controller controls the overflow warning light 60 to emit red light. At this time, the staff patrolling outside can easily find it and complete the replacement of the garbage storage box 90 in time.

[0042] It is worth noting that the shell of the cover 30 in this embodiment is made of a transparent PC (polycarbonate) board, and the overflow warning light 60 can be completely hidden in the shell, or partially protruded from the shell. Both settings can provide prompts to the staff. In addition, a PC blister light panel can be detachably fixed in the shell, and a soft light strip is attached to the light panel. When the public trash can is in normal use, the light strip emits light and is visible from the top of the cover 30. This setting can be used as a sign of the public trash can, making it easier to be found in a dark environment. Finally, the overflow warning light 60 can also emit light of other colors to distinguish the above two different states.

[0043] It is worth mentioning that the base 10 in this embodiment is provided with a retractable plug, one end of which can be electrically connected to the controller, the overflow indicator light 60 and other electrical components, and the other end can extend out of the base 10 and be plugged into an external socket to complete the external power supply to the public trash can.

[0044] In this embodiment, the public trash can may further include a projection device 70 , which is mounted on the cover 30 and is used to project picture advertisements. The projection device 70 and the overflow indicator light 60 are both disposed on the same side of the cover 30 .

[0045] Specifically, the main body of the projection device 70 is installed in the cover 30, and the light source of the projection device 70 protrudes from the cover 30 and is inclined toward the ground. When the public trash can works normally, the projection device 70 can project the picture onto the ground in front of the public trash can, and passengers can find the picture when passing by the public trash can. In crowded places such as airports, each public trash can can display advertisements separately, providing more advertising space for the airport and increasing the airport's revenue.

[0046] In addition, by arranging the projection device 70 and the overflow warning light 60 on the same side of the cover body 30, so that both are arranged on the side of the public trash can away from the wall or corner, it is ensured that the advertisement can be projected in front of the public trash can while the overflow warning light 60 is also in a position that is easy for staff to find.

[0047] In this embodiment, the cover body 30 is rotatably mounted on the barrel body 20 .

[0048] Specifically, the cover 30 rotates around the central axis of the barrel body 20. When the public trash can is placed at a designated location in the airport, the cover 30 can be rotated to ensure that the projected advertisement can be adjusted to a suitable position, and the overflow indicator light 60 is easier to be found by the staff.

[0049] In this embodiment, the public trash can may further include a wireless router, which is installed inside the cover 30 and is used to forward network signals.

[0050] Specifically, by installing multiple public trash cans in different locations of the airport, the signal ranges of multiple wireless routers are in contact with and overlapped with each other, so that the interior space of the airport is basically covered by wireless WiFi, which facilitates passengers' wireless Internet access and improves the passengers' user experience.

[0051] Reference Figure 3 In this embodiment, the public trash can may further include a speaker 80 for broadcasting. The speaker 80 is installed on the side wall of the barrel body 20 and is arranged opposite to the installation opening.

[0052] Specifically, the speaker 80 can broadcast passenger travel information in real time, and can also play other voice information such as real-time news, further improving the passenger's experience.

[0053] Preferably, there are two speakers 80 and they are disposed near the lower end of the barrel body 20 . The two speakers 80 are located at the same height and are spaced apart along the side wall of the barrel body 20 .

[0054] Alternatively, in this embodiment, the speaker 80 can also be installed on the cover 30, which can also enable the public trash can to complete the broadcasting function.

[0055] In this embodiment, the public trash can further includes a door body 40, which is rotatably mounted on the barrel body 20 and is used to open and close the mounting opening.

[0056] Specifically, after the garbage storage box 90 is installed in the barrel body 20, the door body 40 closes the installation opening to prevent outsiders from moving the garbage storage box 90 and affecting its reception of garbage.

[0057] Alternatively, in this embodiment, the door body 40 and the barrel body 20 can be arranged to be pull-out type, and the door body 40 is inserted into the interlayer of the barrel body 20. By pulling it out in the interlayer, the door body 40 can be opened and closed to the installation port.

[0058] In this embodiment, the door body 40 and the barrel body 20 are detachably connected via an induction lock 41 .

[0059] The induction lock 41 can be the same as the induction device of the gate in the airport. The staff can unlock the door body 40 with the same work card. While unlocking is simple and convenient, it also effectively prevents outsiders from opening the door body 40 and causing damage to internal electrical components.

[0060] Please continue to refer to Figure 1 and Figure 2 In this embodiment, there are two garbage storage boxes 90 and two garbage delivery ports 21 , and the two garbage delivery ports 21 correspond one to one with the two garbage storage boxes 90 .

[0061] Specifically, the two garbage storage boxes 90 can correspond to recyclable garbage and non-recyclable garbage respectively. At this time, the number of sensors 50 on the cover body 30 is also two, and the two sensors 50 correspond one-to-one to the two garbage storage boxes 90. When any one of the two sensors 50 detects that the garbage contained in the corresponding garbage storage box 90 is about to overflow, the overflow warning light 60 will emit red light to remind the staff.

[0062] Please continue to refer to Figure 3 In this embodiment, the public trash can further includes an LED lamp 110, and there are multiple LED lamps 110. The multiple LED lamps 110 are installed at the lower end of the barrel body 20 and are used to illuminate the ground.

[0063] Specifically, the base 10 is preferably a cylindrical structure with a diameter smaller than that of the barrel body 20. The LED lights 110 are evenly distributed circumferentially on the lower end surface of the barrel body 20. The LED lights 110 emit light and shine toward the ground. The LED lights 110 can illuminate the ground around the public trash can, making it convenient to remind outsiders of the location of the public trash can.

[0064] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
