DETAILED DESCRIPTION

[0029] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0030] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0031] The present invention will be further described below in conjunction with embodiments and drawings:

[0032] Embodiment 1: As shown in the attached Figure 1-3 As shown, the garbage inlet cover comprises an outer cover 1, an inner cover 2 and a protective plate. The outer cover 1 is provided with an opening which passes through from top to bottom. The outer cover 1 corresponding to the position of the opening is covered with the inner cover 2. The inner cover 2 corresponding to the position around the opening is provided with a protective plate arranged around the opening. An accommodating groove 3 is provided on the inner wall of the opening corresponding to the position of the protective plate. The protective plate is located in the accommodating groove 3 and the inner cover 2 can be lifted upward relative to the outer cover 1.

[0033] When in use, the garbage inlet cover is installed on a garbage bin, and the upper front side of the garbage bin has an inclined box wall inclined from front to back and from bottom to top, a garbage inlet 10 is opened on the inclined box wall, and a hinge shaft 5 is arranged on the outer side of the box wall above the garbage inlet 10, the rear side of the outer cover 1 is hinged on the hinge shaft 5, and the rear side of the inner cover 2 is hinged on the hinge shaft 5 or hinged on the outer cover 1, so that the front side of the inner cover 2 can be lifted upward relative to the outer cover 1. When garbage needs to be thrown in, it is only necessary to lift the outer cover 1 to open the garbage inlet 10 on the garbage bin to throw in the garbage, and when the garbage in the garbage bin is When the garbage is full, the garbage will push up the inner cover plate 2 through the opening. However, due to the setting of the protective plate, when the inner cover plate 2 is pushed up, the protective plate can block the wedge-shaped opening formed between the inner cover plate 2 and the outer cover plate 1, thereby preventing the smell and garbage in the garbage bin from leaking and overflowing through the opening between the inner cover plate 2 and the outer cover plate 1, ensuring the environment around the garbage bin. In addition, since the garbage thrower can intuitively observe that the inner cover plate 2 is pushed up and the protective plate is higher than the placement groove 3, it can be known that the garbage inside the garbage bin is full, so the garbage is thrown into another garbage bin, which can serve as a reminder to the garbage thrower. The structural design of this application is ingenious. It can not only serve as a reminder when the garbage in the garbage bin is full, but also prevent the smell in the garbage bin from leaking and the garbage from overflowing. The protective plate is easy to manufacture and has a low manufacturing cost.

[0034] The above embodiment 1 may be further optimized and / or improved according to actual needs:

[0035] As attached Figure 1-3As shown in the figure, the protection plate includes several single plates 4 sleeved together in sequence from the inside to the outside. The upper end of the single plate 4 located at the innermost side is fixedly connected to the bottom surface of the inner cover plate 2. Among every two adjacent single plates 4, a lower edge 6 is provided on the outer side of the bottom of the single plate 4 located on the inner side, and an upper edge 7 is provided on the inner side of the top of the single plate 4 located on the outer side. The lower edge 6 can move upward and abut against the upper edge 7 when the inner cover plate 2 is lifted upward relative to the outer cover plate 1. A first limiting edge 8 is provided on the outer side of the lower end of the single plate 4 located at the outermost side, and a second limiting edge is provided on the inner wall of the placement groove 3 at a position corresponding to the upper side of the first limiting edge 8. The first limiting edge 8 can move upward and abut against the second limiting edge when the inner cover plate 2 is lifted upward relative to the outer cover plate 1. When the height at which the inner cover plate 2 is lifted relative to the outer cover plate 1 is relatively high, the height of the wedge-shaped opening formed between the inner cover plate 2 and the outer cover plate 1 is higher. Therefore, a relatively high protection plate is required to block the wedge-shaped opening. However, in order to facilitate garbage disposal, the height of the protection plate cannot be very high, which thus limits the lifting height of the inner cover plate 2. In this application, the protection plate is a telescopic protection plate structure composed of several single plates 4 sleeved together in sequence. When the protection plate is in a contracted state, the total height is not very high and it can be completely contracted in the placement groove 3. When the inner cover plate 2 is lifted upward, the single plates 4 extend out one by one, and the protection plate unfolds, thereby ensuring that the inner cover plate 2 can be lifted to a higher height relative to the outer cover plate 1. In this embodiment, the protection plate includes 3 single plates 4 sleeved together in sequence from the inside to the outside.

[0036] As shown in the Figure 1-3 figure, the garbage inlet cover plate further includes a hinge shaft 5. The rear side of the outer cover plate 1 is hinged on the hinge shaft 5, the rear side of the inner cover plate 2 is hinged on the hinge shaft 5 or hinged on the outer cover plate 1, and the front side of the inner cover plate 2 can be lifted upward relative to the outer cover plate 1. Thus, when installed at the position of the garbage bin inlet, only the hinge shaft 5 needs to be installed on the garbage bin, further improving the installation efficiency.

[0037] Preferably, a warning sign layer is provided on the outer side of the single plate 4. By providing the warning sign layer, it is convenient for people to more intuitively observe the protection plate. In this embodiment, the warning sign layer can be a red coating applied on the outer side of the single plate 4.

[0038] Specifically, both the outer cover plate 1 and the inner cover plate 2 are rectangular. A rectangular opening is provided in the middle of the outer cover plate 1, and the rear end of the opening extends to the rear end of the outer cover plate 1. The rear side of the inner cover plate 2 is hinged on the hinge shaft 5. The single plate 4 is a "C"-shaped plate that penetrates up and down around the front side, left side, and right side of the opening and has an opening facing the rear. The rear end of the single plate 4 is hingedly connected to the hinge shaft 5, and the heights of the left and right side plates of the single plate 4 gradually decrease from the front to the rear. Thus, when the front side of the inner cover plate 2 is lifted upward relative to the outer cover plate 1, a wedge-shaped opening that is larger at the front and smaller at the rear is formed between the inner cover plate 2 and the outer cover plate 1, and the "C"-shaped protection plate can well block the wedge-shaped opening.

[0039] Embodiment 2: The only difference between this embodiment and embodiment 1 is that the protective plate includes a single plate 4, the upper end of which is fixedly connected to the bottom surface of the inner cover plate 2, and a first limit rib 8 is provided on the outer side of the lower end of the single plate 4, and a second limit rib is provided on the inner wall of the mounting groove 3 corresponding to the position above the first limit rib 8, and the first limit rib 8 can move upward and resist the second limit rib when the inner cover plate 2 is lifted upward relative to the outer cover plate 1.

[0040] Embodiment 3: As shown in the attached Figure 4-10 As shown, a trash bin using the above-mentioned trash opening cover comprises a trash bin body and a trash opening cover, wherein the trash bin body is provided with a trash opening 10, and an outer cover 1 for opening and closing the trash opening 10 is hingedly connected to the trash bin body corresponding to the trash opening 10, and the outer cover 1 can open the trash opening 10 when flipped upward. Thus, the trash bin can not only play a prompting role when the trash is full, but also prevent the smell in the trash bin from leaking out and the trash from overflowing.

[0041] The above-mentioned embodiment 3 may be further optimized and / or improved according to actual needs:

[0042] As attached Figure 4-10 As shown, the garbage inlet 10 faces upward or front-upward, and a hinge shaft 5 is provided on the garbage bin body corresponding to the position of the garbage inlet 10, the rear side of the outer cover plate 1 is hinged on the hinge shaft 5, the rear side of the inner cover plate 2 is hinged on the hinge shaft 5 or hinged on the outer cover plate 1, and the front side of the inner cover plate 2 can be lifted upward relative to the outer cover plate 1. Thus, the outer cover plate 1 hingedly connected to the garbage bin body can be sealed on the garbage inlet 10 under the action of its own gravity, and the garbage piled up after the garbage bin body is full can lift up the inner cover plate 2. In this embodiment, the rear side of the inner cover plate 2 is hinged on the hinge shaft 5.

[0043] As attached Figure 4-10As shown in the figure, the protective plate includes several single plates 4 sleeved together in sequence from the inside to the outside. The upper end of the single plate 4 located at the innermost side is fixedly connected to the bottom surface of the inner cover plate 2. Among every two adjacent single plates 4, a lower edge 6 is provided on the outer side of the bottom of the single plate 4 located on the inner side, and an upper edge 7 is provided on the inner side of the top of the single plate 4 located on the outer side. When the inner cover plate 2 is lifted upward relative to the outer cover plate 1, the lower edge 6 can move upward to abut against the upper edge 7. A first limiting edge 8 is provided on the outer side of the lower end of the single plate 4 located at the outermost side, and a second limiting edge is provided on the inner wall of the placement groove 3 at a position corresponding to the upper side of the first limiting edge 8. When the inner cover plate 2 is lifted upward relative to the outer cover plate 1, the first limiting edge 8 can move upward to abut against the second limiting edge. When the height of the inner cover plate 2 lifted relative to the outer cover plate 1 is relatively high, the height of the wedge-shaped opening formed between the inner cover plate 2 and the outer cover plate 1 is higher. Therefore, a relatively high protective plate is required to block the wedge-shaped opening. However, in order to facilitate garbage disposal, the height of the protective plate cannot be very high, which thus limits the lifting height of the inner cover plate 2. In this application, the protective plate is a telescopic protective plate structure composed of several single plates 4 sleeved together in sequence. When the protective plate is in a contracted state, the total height is not very high and can be completely retracted into the placement groove 3. When the inner cover plate 2 is lifted upward, the single plates 4 extend out one by one, and the protective plate unfolds to ensure that the inner cover plate 2 can be lifted to a higher height relative to the outer cover plate 1. In this embodiment, the protective plate includes 3 single plates 4 sleeved together in sequence from the inside to the outside.

[0044] Preferably, a warning identification layer is provided on the outer side of the single plate 4. By setting the warning identification layer, it is convenient for people to observe the protective plate more intuitively. In this embodiment, the warning identification layer can be a red coating applied on the outer side of the single plate 4.

[0045] Specifically, both the outer cover plate 1 and the inner cover plate 2 are rectangular. A rectangular opening is provided in the middle of the outer cover plate 1, and the rear end of the opening extends to the rear end of the outer cover plate 1. The rear side of the inner cover plate 2 is hinged on the hinge shaft 5. The single plate 4 is a "C"-shaped plate that penetrates up and down around the front side, left side, and right side of the opening and has an opening facing backward. The rear end of the single plate 4 is hinged to the hinge shaft 5, and the heights of the left and right side plates of the single plate 4 gradually decrease from the front to the rear. Thus, when the front side of the inner cover plate 2 is lifted upward relative to the outer cover plate 1, a wedge-shaped opening that is larger at the front and smaller at the rear is formed between the inner cover plate 2 and the outer cover plate 1, and the "C"-shaped protective plate can block the wedge-shaped opening well.

[0046] As shown in the attached Figure 7-10As shown, the trash bin also includes a cover driving mechanism for driving the outer cover 1 to flip, and the cover driving mechanism includes a push arm and a driving member. The hinge shaft 5 is hingedly connected with a push arm that can rotate relative to the outer cover 1. The push arm and the lower surface of the outer cover 1 are against each other, and the push arm can push the outer cover 1 to flip upward around the hinge shaft 5 when flipping upward around the hinge shaft 5. The push arm is connected with a driving member for driving the push arm to flip upward around the hinge shaft 5, and the driving member is installed in the trash bin body. The push arm is driven to flip upward around the hinge shaft 5 by the driving member, and then the outer cover 1 is pushed to flip upward around the hinge shaft 5 to achieve the purpose of automatically opening the garbage inlet 10. In addition, since the push arm and the outer cover 1 are only against each other but not fixedly connected, the outer cover 1 can be directly lifted manually to open the garbage inlet 10.

[0047] As attached Figure 7-10 As shown, the push arm includes a push rod 11, a connecting rod 12, a hinge shaft 5 sleeve and a counterweight 13. The hinge shaft 5 sleeve is rotatably sleeved on the outside of the hinge shaft 5. One end of the push rod 11 is fixedly connected to the hinge shaft 5 sleeve. The push rod 11 and the lower surface of the outer cover plate 1 are against each other. One end of the connecting rod 12 is fixedly connected to the hinge shaft 5 sleeve. The other end of the connecting rod 12 is connected to the counterweight 13. The driving member includes an electric push rod 14 hinged in the garbage bin body. The piston rod of the electric push rod 14 is hinged to the middle part of the connecting rod 12. The push rod 11 can be turned upward around the hinge shaft 5 when the piston rod of the electric push rod 14 extends outward to push the outer cover plate 1 to turn upward around the hinge shaft 5. By setting the counterweight 13, when the piston rod of the electric push rod 14 moves, the piston rod of the electric push rod 14 is prevented from being stressed in one direction, so that the piston rod of the electric push rod 14 is stressed more evenly, thereby extending the service life of the electric push rod 14.

[0048] Specifically, the cover driving mechanism also includes a sensor, a controller, a battery and a solar panel. The electric push rod 14, the sensor and the battery are all connected to the controller, and the solar panel is connected to the battery. According to the needs, the sensor, the controller, the battery and the solar panel can all adopt the existing known technology. The sensor can be a radar sensor, and the controller can be a PLC programmable controller. By setting the sensor, when a person approaches the garbage bin, the sensor sends a signal to the controller, and the controller controls the piston rod of the electric push rod 14 to extend to lift the outer cover 1 to open the garbage opening 10. When the person is away from the garbage bin, the sensor sends a signal to the controller, and the controller controls the piston rod of the electric push rod 14 to retract, and the outer cover 1 descends to close the garbage opening 10 again, thereby achieving the purpose of automatically opening and closing the garbage opening 10. By setting the solar panel to power the control system of the cover driving mechanism, the operating cost is saved.

[0049] As attached Figure 4-10As shown, the trash bin body is enclosed by a front box wall, a rear box wall 15, an upper box wall 16, a lower box wall 17, a left box wall and a right box wall. The front box wall includes a lower vertical plate portion 18, an inclined plate portion 19 and an upper vertical plate portion 20 connected in sequence from bottom to top. The inclined plate portion 19 is inclined from front to back and from bottom to top. The garbage inlet 10 is arranged on the inclined plate portion 19. A partition is arranged in the trash bin body corresponding to the position of the garbage inlet 10. The partition divides the interior of the trash bin body into a first receiving chamber 21 and a second receiving chamber 22. The garbage inlet 10 is connected to the first receiving chamber 21, and the second receiving chamber 22 is located above the rear of the first receiving chamber 21. The partition includes a garbage baffle portion 24 and a connecting plate portion 25. The upper end of the garbage baffle portion 24 and the trash bin body The garbage baffle portion 24 is fixedly connected to the box wall, the lower end of the garbage baffle portion 24 is fixedly connected to the front end of the connecting plate portion 25, and the rear end of the connecting plate portion 25 is fixedly connected to the box wall of the garbage bin body. A garbage can 23 with an open top is provided in the first accommodating chamber 21 corresponding to the position below the garbage inlet 10, the garbage baffle portion 24 is located above the middle part of the garbage can 23, and the lower end of the garbage baffle portion 24 is 2 cm to 30 cm away from the top of the garbage can 23. A garbage can 23 replacement port is provided on the lower vertical plate portion 18 corresponding to the position of the garbage can 23, and the top of the garbage can 23 replacement port is 2 cm to 15 cm higher than the top of the garbage can 23. A first box door 26 is provided at the garbage can 23 replacement port, and a second box door 27 is provided on the rear box wall 15 corresponding to the position of the second accommodating chamber 22. The internal space of the trash can body is divided into a first receiving chamber 21 and a second receiving chamber 22 by a partition. A trash can 23 is placed in the first receiving chamber 21, and the second receiving chamber 22 is located above the rear of the trash can 23. Thus, the space in the trash can body above the rear of the trash can 23 is fully utilized, which greatly improves the space utilization rate. The second receiving chamber 22 can be used as a tool room, and some cleaning tools such as a broom and a dustpan can be placed therein, thereby increasing the function of the trash can. When in use, as garbage is continuously thrown in from the garbage inlet 10, the garbage will gradually rise above the trash can 23 until the inner cover plate 2 is lifted up by the garbage to remind people that the trash can is full of garbage. Due to the setting of the garbage baffle portion 24, the garbage that rises above the trash can 23 is basically blocked by the garbage baffle portion 24 is on the left side, while the upper rear space of the trash can 23 located on the right side of the trash baffle is not filled with trash to form residual space. According to needs, when the trash can 23 is full of trash and is lifted up, the volume of trash above the replacement port of the trash can 23 is smaller than the volume of the remaining space of the trash can 23. Therefore, when the trash can 23 is pulled outward through the replacement port of the trash can 23, the trash at the top of the trash can 23 is blocked by the top wall of the replacement port of the trash can 23, and thus falls into the remaining space in the upper rear part of the trash can 23, thereby avoiding the problem of trash scattering everywhere when the trash can 23 is pulled outward due to high trash accumulation, and facilitating the rapid removal of trash. In this embodiment, the lower end of the trash baffle portion 24 is 5 cm away from the top of the trash can 23, and the top of the replacement port of the trash can 23 is 2 cm higher than the top of the trash can 23.

[0050] The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
