DETAILED DESCRIPTION

[0035] 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.

[0036] 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.

[0037] The present invention will be further described below in conjunction with embodiments and drawings:

[0038] Implementation 1: As attached Figure 1-3 As shown, the garbage delivery port cover comprises an outer cover 1, an inner cover 2 and a flexible protective cover 3. The outer cover 1 is provided with an opening which passes through from top to bottom. The outer cover 1 corresponding to the opening position is covered with an inner cover 2 which can be lifted upward relative to the outer cover 1. The inner cover 2 corresponding to the peripheral position of the opening is provided with a flexible protective cover 3 which is arranged around the opening. The flexible protective cover 3 can be unfolded when the inner cover 2 is lifted upward relative to the outer cover 1.

[0039] 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. When the garbage in the garbage bin is full of garbage, The garbage will push up the inner cover plate 2 through the opening. However, due to the setting of the flexible protective cover 3, the flexible protective cover 3 will unfold when the inner cover plate 2 is pushed up, and the wedge-shaped opening formed between the inner cover plate 2 and the outer cover plate 1 will be blocked by the protective cover, 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, thereby ensuring the environment around the garbage bin. In addition, since the garbage disposal personnel can intuitively observe that the inner cover plate 2 is pushed up and the folding sleeve is unfolded, 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 disposal personnel. 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.

[0040] The above embodiment 1 may be further optimized and / or improved according to actual needs:

[0041] As attached Figure 2-3 As shown, the top of the inner wall of the opening is provided with an inner ring groove 4 surrounding the opening, and the lower end of the flexible protective cover 3 is fixedly connected to the bottom wall of the inner ring groove 4. When the inner cover plate 2 is not lifted, the flexible protective cover 3 is located in the inner ring groove 4, thereby protecting the flexible protective cover 3 and extending its service life.

[0042] The flexible protective cover 3 is an accordion-type protective cover, so the flexible protective cover 3 has low manufacturing cost, long service life and wide sources.

[0043] A warning marking layer is provided on the outside of the flexible protective cover 3. The warning marking layer is provided to facilitate personnel to more intuitively observe the flexible protective cover 3 in the unfolded state. In this embodiment, the warning marking layer can be a red coating coated on the outside of the flexible protective cover 3.

[0044] As attached Figure 1-3 As shown, the garbage inlet cover also includes a hinge shaft 5, the rear side of the outer cover 1 is hinged on the hinge shaft 5, the rear side of the inner cover 2 is hinged on the hinge shaft 5 or hinged on the outer cover 1, and the front side of the inner cover 2 can be lifted upward relative to the outer cover 1. Therefore, when installing it at the garbage bin inlet, it only needs to install the hinge shaft 5 on the garbage bin, which further improves the installation efficiency.

[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 flexible protective cover 3 is a "C"-shaped flexible protective cover 3 that surrounds the front side, left side, and right side peripheries of the opening, is vertically through, and has an opening facing backward. 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 flexible protective cover 3 can well block this wedge-shaped opening.

[0046] Embodiment 2: As shown in the attached Figure 4 figure, the difference between this embodiment and Embodiment 1 is only that: a border 6 surrounding the flexible protective cover 3 is provided on the inner cover plate 2 corresponding to the outer side position of the flexible protective cover 3. The bottom of the border 6 abuts against the upper surface of the outer cover plate 1, and the lower end of the flexible protective cover 3 is fixedly connected to the upper surface of the outer cover plate 1. The border 6 plays a supporting role for the inner cover plate 2, thereby preventing the inner cover plate 2 from directly pressing on the flexible protective cover 3 and extending the service life of the flexible protective cover 3. In addition, the border 6 also plays a protective role for the flexible protective cover 3, preventing it from being exposed to the sun and rain, and further extending its service life.

[0047] Embodiment 3: As shown in the attached Figure 5 figure, the difference between this embodiment and Embodiment 1 is only that: an inner ring groove 4 surrounding the opening is provided on the inner wall of the opening. A counterweight plate 7 surrounding the opening is provided in the inner ring groove 4. The counterweight plate 7 sits on the bottom wall of the inner ring groove 4, and the lower end of the flexible protective cover 3 is fixedly connected to the counterweight plate 7 together. Thus, it is ensured that the bottom end of the flexible protective cover 3 will not come out of the inner ring groove 4 when the inner cover plate 2 is lifted, so as to block the wedge-shaped opening between the inner cover plate 2 and the outer cover plate 1.

[0048] Embodiment 4: As shown in the attached Figure 6 figure, the difference between this embodiment and Embodiment 1 is only that: an inner ring groove 4 surrounding the opening is provided on the inner wall of the opening. The inner ring groove 4 is vertically through. A plurality of support columns 8 are provided at intervals along the circumferential direction of the bottom edge of the inner ring groove 4. A counterweight plate 7 surrounding the opening is provided below the inner ring groove 4 corresponding to the inner side position of the plurality of support columns 8. An outer ring 9 slidably sleeved on the corresponding support column 8 is fixedly connected to the outer side of the counterweight plate 7 corresponding to each support column 8. A limit boss for preventing the outer ring 9 from falling off is provided at the bottom of the support column 8. The lower end of the flexible protective cover 3 is fixedly connected to the counterweight plate 7 together. Thus, it is ensured that the bottom end of the flexible protective cover 3 will not come out of the inner ring groove 4 when the inner cover plate 2 is lifted, so as to block the wedge-shaped opening between the inner cover plate 2 and the outer cover plate 1.

[0049] Embodiment 5: As shown in the attached Figure 7-13As shown in the figure, a dustbin using the above-mentioned garbage chute cover plate includes a dustbin body and a garbage chute cover plate. A garbage chute 10 is provided on the dustbin body. At the position corresponding to the garbage chute 10, the dustbin body is hingedly connected with an outer cover plate 1 for opening and closing the garbage chute 10, and the outer cover plate 1 can open the garbage chute 10 when it is turned upwards. Thus, this dustbin can not only play a prompting role when the garbage is full, but also prevent the odor in the dustbin from leaking out and the garbage from overflowing.

[0050] According to actual needs, the above-mentioned Embodiment 5 can be further optimized or / and improved as follows:

[0051] As shown in the attached Figure 7-13 figure, the garbage chute 10 faces upwards or frontally upwards. At the position of the dustbin body corresponding to the garbage chute 10, a hinge shaft 5 is provided. The rear side of the outer cover plate 1 is hinged on the hinge shaft 5, and the rear side of the inner cover plate 2 is hinged on the hinge shaft 5 or hinged on the outer cover plate 1. The front side of the inner cover plate 2 can be lifted upwards relative to the outer cover plate 1. Thus, the outer cover plate 1 hinged on the dustbin body can cover the garbage chute 10 under its own gravity. After the garbage in the dustbin is full, the piled-up garbage can lift the inner cover plate 2. In this embodiment, the garbage chute 10 faces frontally upwards, and the rear side of the inner cover plate 2 is hinged on the hinge shaft 5.

[0052] Specifically, both the outer cover plate 1 and the inner cover plate 2 are rectangular. A rectangular opening is formed 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 flexible protective cover 3 is a "C"-shaped flexible protective cover 3 that surrounds the front side, left side, and right side peripheries of the opening and is vertically through and has an opening facing backwards. Thus, when the front side of the inner cover plate 2 is lifted upwards 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. The "C"-shaped flexible protective cover 3 can well block this wedge-shaped opening. Since the height of the wedge-shaped opening gradually decreases from the front to the rear, the heights of the left and right sides of the flexible protective cover 3 can gradually decrease from the front to the rear.

[0053] As shown in the attached Figure 10-13 figure, this dustbin further includes a cover plate driving mechanism for driving the outer cover plate 1 to flip. The cover plate driving mechanism includes a push arm and a driving member. A push arm that can rotate relative to the outer cover plate 1 is hingedly connected to the hinge shaft 5. The push arm abuts against the lower surface of the outer cover plate 1, and the push arm can push the outer cover plate 1 to flip upwards around the hinge shaft 5 when it rotates upwards around the hinge shaft 5. A driving member for driving the push arm to rotate upwards around the hinge shaft 5 is connected to the push arm, and the driving member is installed in the dustbin body. By driving the push arm to rotate upwards around the hinge shaft 5 through the driving member, and then pushing the outer cover plate 1 to flip upwards around the hinge shaft 5 to achieve the purpose of automatically opening the garbage chute 10. In addition, since the push arm only abuts against the outer cover plate 1 instead of being fixedly connected, the outer cover plate 1 can be directly lifted manually to open the garbage chute 10.

[0054] As attached Figure 10-13 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.

[0055] Preferably, 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 requirements, 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.

[0056] As attached Figure 7-13As shown, the garbage 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 garbage bin body corresponding to the position of the garbage inlet 10. The partition divides the interior of the garbage 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 garbage receiving chamber 22 are connected. The box wall of the box body is fixedly connected, 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 box 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, and the garbage baffle portion 24 is located above the middle part of the garbage can 23. 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 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 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 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 On the left side of the garbage baffle portion 24, the upper rear space of the garbage can 23 located on the right side of the garbage baffle is not filled with garbage to form residual space. According to needs, when the inner cover 2 is lifted up when the garbage in the garbage can is overflowing, the volume of garbage above the garbage can replacement port is smaller than the volume of the remaining space in the garbage can. Therefore, when the garbage can 23 is pulled outward through the garbage can replacement port, the garbage at the top of the garbage can 23 is blocked by the top wall of the garbage can replacement port, and thus falls into the remaining space in the upper rear portion of the garbage can 23. This avoids the problem of garbage scattering everywhere when the garbage can 23 is pulled outward due to high garbage accumulation, and facilitates rapid garbage removal. In this embodiment, the lower end of the garbage baffle portion 24 is 5 cm away from the top of the garbage can 23, and the top of the garbage can replacement port is 2 cm higher than the top of the garbage can 23.

[0057] 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.
