[0002] In modern urban environments, public trash cans are important facilities for maintaining environmental hygiene. However, traditional open-air trash cans expose trash to the air for a long time, which makes it easy for it to ferment, especially in high-temperature environments, producing unpleasant odors, affecting pedestrian experience and the appearance of the city. In addition, stray cats and dogs rummage for food, causing trash to be scattered and increasing the difficulty of cleaning.

[0003] For example, the utility model patent (application number: 201920144110.3) discloses a "public trash can," the description of which states that it is specifically a public trash can. This public trash can includes: a can body, a can frame, a cigarette extinguishing channel, and a cigarette extinguishing device. The head end of the cigarette extinguishing channel restricts the movement direction of undisturbed cigarette butts; the cigarette extinguishing device passively or actively extinguishes the cigarette butts; and the tail end of the cigarette extinguishing channel restricts the movement direction of extinguished cigarette butts, ultimately storing the extinguished cigarette butts inside the can. This utility model provides a solution to the technical problem in the prior art where, when workers clean the trash can, in addition to cleaning the can body, they also need to clean cigarette boxes or simple cigarette extinguishers, thus increasing the workload of the workers; the aforementioned patent can corroborate the deficiencies of the prior art.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1 Please refer to Figure 1 and Figure 2A concealed trash can includes a mounting box 1, with its top and bottom open. The top is closed or opened via a flip cover 22. A base plate 21 is fixedly installed at the bottom of the mounting box 1. A lifting plate 51 is slidably installed inside the mounting box 1. A transmission component 6 is installed at the top of the lifting plate 51. During the lifting process, the lifting plate 51 drives the flip cover 22 to flip. Several collection bins 25 are provided at the front end of the transmission component 6. The collection bins 25 are used to collect trash. A flip cover 22 is hinged to one side of the top of the mounting box 1. The flip cover 22 is used to cover the top of the mounting box 1 to prevent pedestrians from falling and foreign objects from entering. A lifting component 3 is installed at the bottom of the lifting plate 51. The lifting component 3 is used to drive the lifting plate 51 to lift and lower, thereby allowing the collection bins 25 to be concealed, preventing animals from disturbing the trash inside the collection bins 25, and preventing odors from escaping. A sliding component 4 is provided inside the lifting component 3 to reduce the friction of the lifting component 3 during operation.

[0023] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly 3 includes a drive telescopic rod 34, which includes, but is not limited to, an electric telescopic rod. The upper and lower ends of the front and rear sides of the mounting box 1 are provided with cross arms 31. The four cross arms 31 are located between the base plate 21 and the lifting plate 51. Specifically, the cross arms 31 are two cross-hinged support rods. Two cross arms 31 located on the same side are hinged at their close ends. When the drive telescopic rod 34 extends, it drives the lifting plate 51 to rise through the cross arms 31. When the cross arms 31 shorten, it drives the lifting plate 51 to fall. Fixed rods 32 are fixed at both ends of one of the lower cross arms 31. The fixed rods 32 are used to increase the stability of the cross arm 31 structure. The ends of the two fixed rods 32 are fixedly connected to the ends of the other lower cross arm 31. Fixed rods 32 are also fixed at both ends of one of the upper cross arms 31. The ends of the two fixed rods 32 are fixedly connected to the ends of the other upper cross arm 31. An installation rod 33 is fixedly provided between the two upper cross arms 31. The drive telescopic rod 34 is rotatably connected to the circumferential side of one of the lower fixed rods 32. The output end of the drive telescopic rod 34 is rotatably connected to the circumferential side of the installation rod 33. When the drive telescopic rod 34 extends, the distance between the fixed rod 32 and the installation rod 33 connected to the drive telescopic rod 34 gradually increases. When the drive telescopic rod 34 shortens, the distance between the fixed rod 32 and the installation rod 33 gradually shortens. Limiting telescopic rods 35 are fixedly installed at the four corners of the top of the base plate 21. The ends of the limiting telescopic rods 35 are fixedly connected to the lifting plate 51. The limiting telescopic rods 35 are used to increase the stability of the lifting plate 51 when it is raised or lowered. The outside of the mounting box 1 is equipped with a control panel. The control panel is electrically connected to the drive telescopic rod 34 through the controller. Pedestrians can control the start of the drive telescopic rod 34 through the control panel, so that the lifting assembly 3 drives the collection bucket 25 to extend or retract.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, the sliding assembly 4 includes a limiting plate 42, which is used to limit the rolling range of the pulley 41. The bottom plate 21 and the lifting plate 51 are each provided with two limiting plates 42 on opposite sides. The two limiting plates 42 on the same side are each fixedly provided with connecting blocks 44 at both ends on opposite sides. The four connecting blocks 44 located below are fixedly connected to the bottom plate 21, and the four connecting blocks 44 located above are fixedly connected to the lifting plate 51. The two limiting plates 42 on the same side are each provided with a rolling mechanism on opposite sides. The rolling mechanism is used to reduce the friction at the end of the cross arm 31 and make its operation more stable. The rolling mechanism includes two pulleys 41, which are rotatably connected to the ends of the closest cross arms 31. When the drive telescopic rod 34 is activated to drive the cross arms 31, the lower ends of the lower cross arms 31 and the upper ends of the upper cross arms 31 drive the pulleys 41 to roll on the base plate 21 and the lifting plate 51, achieving stable operation while reducing friction. Limiting strips 43 are provided above and below the front and rear ends of the two pulleys 41. The rolling range of the pulleys 41 is limited by the limiting strips 43 to prevent them from moving out of the designated position. The two limiting strips 43 closest to the limiting plate 42 are fixedly connected to the limiting plate 42, the two limiting strips 43 closest to the base plate 21 are fixedly connected to the base plate 21, and the two limiting strips 43 closest to the lifting plate 51 are fixedly connected to the lifting plate 51.

[0025] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, the transmission assembly 6 includes a support base 61, which is used to support and install the connecting rod 62. The support base 61 is fixed to the top of the lifting plate 51. The top of the support base 61 is provided with several sliding rods 63. The top of the sliding rods 63 is hinged to the flip cover 22. When the lifting plate 51 moves up and down, it drives the flip cover 22 to open or close. An alarm light and a speaker are provided on the outside of the mounting box 1. When the lifting assembly 3 needs to drive the lifting plate 51 to rise or fall, the alarm light and speaker will provide visual and auditory alarms to the surrounding people, prompting them to stay away from the mounting box 1.

[0026] Example 2 The concealed trash can provided in Example 1 is further optimized, specifically, as follows: Figure 2 , Figure 5 and Figure 6 As shown, the transmission assembly 6 also includes a connecting rod 62 located below the slide rod 63. The bottom end of the connecting rod 62 is hinged to the support base 61, and the top end of the connecting rod 62 is provided with a sliding groove 65. The slide rod 63 is slidably connected to the inside of the sliding groove 65. A piston 64 is fixedly provided at the bottom end of the slide rod 63. The piston 64 keeps the inside of the sliding groove 65 in a sealed state. The piston 64 is slidably connected to the inside of the sliding groove 65. As the slide rod 63 slides inside the sliding groove 65, the air pressure inside the sliding groove 65 increases or decreases through the piston 64. Due to the characteristic that gas is easily compressible, when the transmission assembly 6 drives the flip cover 22 to flip by the up and down movement of the lifting plate 51, it can have a certain buffer distance to avoid hard pulling that makes the parts more easily damaged. When the lifting plate 51 moves down, causing the slide rod 63 to drive the flip cover 22 back to the top of the mounting box 1, the lifting plate 51 continues to move down through the lifting assembly 3, which lengthens the distance between the slide rod 63 and the connecting rod 62. The slide rod 63 and the piston 64 slide inside the slide groove 65, thereby reducing the air pressure inside the slide groove 65 and generating an adsorption force to adsorb the piston 64 and the slide rod 63. This makes the sealing gasket 23 on the flip cover 22 contact the mounting box 1 more tightly, increasing the sealing performance.

[0027] Furthermore, such as Figure 5 As shown, a sealing gasket 23 is fixedly provided at the front end of the flip cover 22. The sealing gasket 23 is used to increase the sealing performance when in contact with the top of the mounting box 1, and to prevent foreign objects or liquids from entering the interior of the mounting box 1. Together with the transmission component 6, it can make it close more tightly.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, the base plate 21 has several connection holes 24. The connection holes 24 are used to drain the water inside the installation box 1 to prevent water accumulation inside the installation box 1 in humid climate. The connection holes 24 are connected to the sewer through pipes or to other containers through pipes for drainage.

[0029] Example 3 The concealed trash cans provided in Embodiments 1 and 2 are further optimized, such as... Figure 1 and Figure 7As shown, several collection bins 25 are equipped with the same protective component 7 at their front ends. The protective component 7 is used to restrain the collection bins 25 to prevent them from tipping over during lifting and lowering, while also facilitating the entry and exit of the collection bins 25. The protective component 7 includes a first limiting plate 71 fixedly connected to the top of the lifting plate 51. A second limiting plate 72 is provided on one side of the first limiting plate 71. Both the first limiting plate 71 and the second limiting plate 72 are "L"-shaped and are symmetrically arranged. The second limiting plate 72 is fixedly connected to the top of the lifting plate 51. A door 73 is provided on the side of 71 closest to the second limiting plate 72. The door 73 is flipped outward to facilitate the removal of the collection bucket 25. The door 73 is hinged to the first limiting plate 71 by a torsion spring. When the door 73 is released, the torsion spring causes the door 73 to close automatically. The front end of the side of the second limiting plate 72 closest to the first limiting plate 71 and the rear end of the door 73 closest to the second limiting plate 72 are both provided with connecting grooves 74. When the door 73 closes and contacts the second limiting plate 72, the connecting groove 74 on the second limiting plate 72 contacts and engages with the connecting groove 74 on the door 73.

[0030] Furthermore, such as Figure 1 and Figure 7 As shown, the top of the lifting plate 51 is provided with a cleaning component 8. The cleaning component 8 includes a cleaning frame 81 fixed to the top of the lifting plate 51. The transmission component 6, the protective component 7 and several collection buckets 25 are all located inside the cleaning frame 81. The top of the inside of the cleaning frame 81 is provided with a slope. The slope allows the garbage falling on the cleaning frame 81 to be guided into the inside of the lifting plate 51, so as to avoid getting stuck in the gap between the lifting plate 51 and the mounting box 1.

[0031] Furthermore, such as Figure 7 As shown, the cleaning assembly 8 also includes a guide frame 82 fixed inside the cleaning frame 81. The top of the guide frame 82 is lower than the cleaning frame 81. The cleaning frame 81 is made of melamine sponge, which has a certain rigidity support structure and can absorb liquids such as lubricating oil. The guide frame 82 is fixedly connected to the lifting plate 51. The top of the guide frame 82 is also provided with a slope. The slope on the guide frame 82 and the slope on the cleaning frame 81 form a groove. When it is necessary to apply lubricating oil between the lifting plate 51 and the mounting box 1 to reduce friction, the lubricating oil is poured into the groove formed by the inclined surface between the guide frame 82 and the cleaning frame 81, so that the lubricating oil is guided through the groove until it is filled with the entire groove, and absorbed by the cleaning frame 81. When the lifting plate 51 moves up and down through the lifting assembly 3, the cleaning frame 81, which has absorbed the lubricating oil, applies the lubricating oil to the inner wall of the mounting box 1, and then the lubricating oil covers the edge of the lifting plate 51 through the inner wall of the mounting box 1, thus facilitating the application of lubricating oil.

[0032] The usage process of the concealed trash can provided by this utility model is as follows: When a concealed trash can needs to be installed, a mounting slot is made in the ground to install the mounting box 1, and the mounting box 1 is installed inside it. The control panel is placed on the ground outside the mounting slot for easy use, and the alarm light and speaker are also installed on the ground outside the mounting slot for easy notice by pedestrians. When it is necessary to raise the collection bin 25 to dispose of garbage, the connection hole 24 is activated via the control panel. Before the connection hole 24 is activated, an alarm light and a speaker will alert pedestrians to stay away from the mounting box 1 and the flip cover 22. Then, the connection hole 24 extends normally, which drives the folded cross arm 31 to unfold. At the same time, the lower ends of the lower cross arm 31 and the upper ends of the upper cross arm 31 drive the pulley 41 to roll on the base plate 21 and the lifting plate 51, causing the lifting plate 51 to rise. The flip cover 22 is pushed upward through the connecting rod 62 and the sliding rod 63, causing the flip cover 22 to open. Then, the lifting plate 51 and the collection bin 25 extend, making it convenient for pedestrians to dispose of garbage into the collection bin 25. After the collection is completed, the telescopic rod 34 is driven to retract and hide the collection bucket 25. An alarm light and speaker remind the user again. Then, the telescopic rod 34 is driven to retract, which drives the lifting plate 51 to descend via the cross arm 31 and the sliding assembly 4. The flip cover 22 is then closed via the connecting rod 62 and the sliding rod 63. The flip cover 22 contacts the top of the mounting box 1 through the sealing gasket 23. When the flip cover 22 contacts the top of the mounting box 1, the telescopic rod 34 continues to move, which drives the lifting plate 51 to move down a certain distance via the lifting assembly 3 and the sliding assembly 4. This lengthens the distance between the sliding rod 63 and the connecting rod 62. The sliding rod 63 and the piston 64 slide inside the slide groove 65, which reduces the air pressure inside the slide groove 65 and generates an adsorption force to attract the piston 64 and the sliding rod 63. This pulls the flip cover 22, making it more tightly sealed with the sealing gasket 23 and increasing the airtightness.
