Description

Technical Field

[0001] This technical solution relates to the field of trash can technology, specifically a double-lid trash can. Background Technology

[0002] A trash can is a container for holding trash. When in use, a plastic bag is placed inside the container, and when there is too much trash, the bag can be tied up and thrown away.

[0003] Existing trash cans include double-lid trash cans, which include a first lid and a second lid. The first lid is used to cover the rim of the trash bag and for decoration, and the second lid is used to open or close the trash can. The pivot of the second lid is connected to the first lid, and the second lid will rotate and open synchronously with the first lid; or a trash can with a trash bag fastening function as disclosed in Chinese Patent CN201410218100.1, which includes: a can body, a can lid, and a fastening frame, wherein the fastening frame is the first lid and the can lid is the second lid;

[0004] However, existing trash cans still have some shortcomings: the first and second lids are only fitted together. When the first lid is opened to change the trash bag, because the opening angle of the first lid is greater than 90 degrees, the second lid cannot stabilize its center of gravity and can no longer fit together with the first lid, causing the second lid to tip over. This tipping can cause deformation or breakage at the pivot point of the second lid. In addition, if the second lid is large in size and weight, such as a stainless steel lid, the sudden tipping will not only make noise, but may also frighten the user, or even hit children or objects behind, posing a safety hazard.

[0005] Currently, to prevent the second lid from tipping over, the maximum opening angle of the first lid is generally limited, meaning the maximum opening angle of the first lid is less than 90 degrees, for example, limiting the maximum opening angle of the first lid to about 75 degrees. However, this method affects the opening angle of the trash can, making it inconvenient to take out and replace the trash bag, thus affecting the user experience. Summary of the Invention

[0006] The purpose of this technical solution is to provide a double-lid trash can. By setting a support part on the second lid, when the second lid is rotated open, the support part abuts against the hinge seat or the can body, thereby restricting the rotation of the second lid and improving the problem of the second lid tipping over when the opening angle of the first lid is greater than 90 degrees.

[0007] The purpose of this technical solution is achieved as follows:

[0008] A double-lid trash can, comprising:

[0009] A barrel body, which has a barrel opening, and the edge of the barrel opening of the barrel body is provided with a hinge seat;

[0010] A first cover has a first connecting part and an opening. The first connecting part is hinged to the hinge seat. The first cover covers the edge of the barrel opening, and the opening communicates with the barrel opening.

[0011] The second cover has a second connecting part, which is hinged to the hinge seat. The second cover is placed on the first cover and is used to open or close the opening.

[0012] A driving device, which is mounted on the second cover or mounted on the barrel and connected to the second cover, is used to drive the second cover to open the opening;

[0013] The second cover is provided with a support portion at its end;

[0014] When the second cover is rotated to open the opening, the support part abuts against the hinge seat or the barrel body, thereby limiting the rotation angle of the second cover.

[0015] Preferably, a limiting member is hinged to the inner wall of the barrel opening, and the limiting member is rotatably positioned at or away from the barrel opening; a receiving groove is provided at the lower end of the first cover.

[0016] After the limiting member is placed inside the barrel opening, the first cover is rotated to cover the barrel opening, so that both the limiting member and the upper end of the barrel opening are placed inside the receiving groove.

[0017] Preferably, the inner wall of the barrel opening is provided with a groove for accommodating the limiting member.

[0018] Preferably, the second cover has two second connecting portions, and the support portion is disposed between the two second connecting portions and integrally formed.

[0019] Preferably, the first cover has two first connecting portions, and the second connecting portion is disposed between the two first connecting portions.

[0020] Preferably, both ends of the hinge seat are provided with a first hinge shaft, the second connecting part is provided with a second hinge shaft and a first hinge groove, the first connecting part is provided with a second hinge groove, the first hinge shaft is inserted into the first hinge groove, and the second hinge shaft is inserted into the second hinge groove.

[0021] Preferably, the axis of the first hinge shaft and the axis of the second hinge shaft coincide.

[0022] Preferably, the first hinge shaft is provided with a first guide surface, one side of the first hinge groove is connected to the end side of the second connecting part, and a first anti-detachment part is provided in the first hinge groove. The first anti-detachment part is provided with a second guide surface. Through the sliding cooperation of the first guide surface and the second guide surface, the first hinge shaft is slidably inserted into the first hinge groove.

[0023] Preferably, the second hinge shaft is provided with a third guide surface, one side of the second hinge groove is connected to the end side of the first connecting part, and a second anti-detachment part is provided in the second hinge groove. A fourth guide surface is provided on the second anti-detachment part. The second hinge shaft is slidably inserted into the second hinge groove through the sliding cooperation of the third guide surface and the fourth guide surface.

[0024] Preferably, the driving device includes: a foot pedal device and / or a lifting device;

[0025] The foot pedal device includes:

[0026] A foot pedal, the middle of which is hinged to the lower end of the barrel, and the front end of the foot pedal extending beyond the lower end of the barrel for the user to step on; and

[0027] A connecting rod is vertically disposed at the rear end of the barrel body, and the lower end of the connecting rod is connected to the rear end of the foot pedal, and the upper end of the connecting rod extends into the hinge seat and abuts against the second cover body;

[0028] The lifting device includes a lifting strap, which is installed in the mounting hole of the second cover.

[0029] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0030] This technical solution involves setting a support part on the second cover. When the second cover is rotated open, the support part abuts against the hinge seat or the bin body, thereby limiting the rotation angle of the second cover. This prevents the second cover from failing to fit with the first cover after the first cover is opened to its maximum angle, thus avoiding the problem of sudden tipping. Both the first and second covers can open to an angle greater than 90 degrees and remain upright without tipping, making it convenient to pick up and replace garbage bags and improving the daily user experience.

[0048] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-11 .

[0049] See Figures 1-3 , Figure 5 and Figure 6 A double-lid trash can, comprising:

[0050] The bin body 1 has a bin opening 11 and a hinge seat 12 is provided on the upper rear side of the bin body 1, that is, the edge of the bin opening 11 is provided with a hinge seat 12. The bin body 1 has a receiving cavity for storing garbage, and the receiving cavity is connected to the outside through the bin opening 11.

[0051] The first cover 2 has a first connecting part 21 and an opening 22. The first connecting part 21 is hinged to the hinge seat 12. The first cover 2 is rotated to cover the edge of the barrel opening 11. The opening 22 is connected to the barrel opening 11.

[0052] The second cover 3 has a second connecting part 31 at its rear end. The second connecting part 31 is hinged to the hinge seat 12. The second cover 3 is rotated to cover the first cover 2, which is used to open or close the opening 22, thereby opening or closing the barrel mouth 11.

[0053] A driving device is installed on the second cover 3 or on the barrel 1 and connected to the second cover 3. The second cover 3 is opened to open the opening 22 by the driving device.

[0054] The second cover 3 has a support 32 at its rear end, and the support 32 and the second connecting part 31 are located on the same side of the second cover 3.

[0055] When the second cover 3 is rotated to open the opening 22, the support part 32 abuts against the hinge seat 12 or the barrel body 1, thereby limiting the rotation angle of the second cover 3.

[0056] When the support part 32 abuts against the hinge seat 12 or the bin body 1, the second cover 3 rotates and opens to the maximum angle. The opening angle of the second cover 3 refers to the angle between the side of the second cover 3 near the bin opening 11 and the horizontal plane (i.e., the ground) where the bin body 1 is located. The maximum opening angle of the second cover 3 is preset to be greater than or equal to 90 degrees, such as 90 degrees or 100 degrees, so that the second cover 3 will not be placed directly above the bin opening 11 after opening, making it convenient and quick to take out the garbage bag. The second cover 3 can stand upright without tipping over through the support part 32, improving the daily user experience.

[0057] The first cover 2 is a ring or circle structure for decoration, to prevent the opening 11 of the bin from being exposed and affecting the appearance. At the same time, after the garbage bag is put on, the first cover 2 can press the edge of the garbage bag onto the opening 11 of the bin, to prevent the garbage bag from being unstable and moving, thus ensuring that the garbage is thrown into the garbage bag and the opening of the garbage bag will not come off.

[0058] When changing garbage bags, the first cover 2 rotates and opens. The rotation range of the first cover 2 is limited between the second cover 3 and the bin 1, so that the maximum opening angle of the first cover 2 is less than or equal to the maximum opening angle of the second cover 3. This allows the first cover 2 to stand upright without tipping over by relying on its own contact with the bin 1 or by relying on the second cover 3, thus improving the daily user experience and the convenience of changing garbage bags.

[0059] The maximum opening angle of both the first cover 2 and the second cover 3 is greater than 90 degrees, and they can stand upright without tipping over.

[0060] Combination Figure 3 , Figure 4 , Figure 7 and Figure 9 A limiting member 4 is hinged to the inner wall of the bin opening 11. The limiting member 4 is a ring or circle structure. The limiting member 4 can be rotated to be placed on or away from the bin opening 11. The limiting member 4 is used to squeeze and fix the opening of the garbage bag to the inner side wall of the bin opening 11, thereby ensuring the stability of the garbage bag after it is placed. A receiving groove 23 is provided at the lower end of the first cover 2.

[0061] After the limiting member 4 is placed inside the bucket opening 11, the first cover 2 is rotated to cover the bucket opening 11, so that the limiting member 4 and the upper end of the bucket opening 11 are both placed in the receiving groove 23, thereby preventing the limiting member 4 and the upper end of the bucket opening 11 from being exposed, improving the aesthetics, and at the same time preventing garbage from soiling the limiting member 4 and the bucket opening 11.

[0062] A further solution is to provide a groove 13 on the inner wall of the bin opening 11. The groove 13 is used to accommodate the limiting member 4. The side wall of the limiting member 4 is in movable contact with the side wall of the groove 13, and the bottom of the limiting member 4 is in movable contact with the bottom of the groove 13, so that the limiting member 4 can hold the opening of the garbage bag in the groove 13, thereby fixing the opening of the garbage bag.

[0063] Combination Figure 10 and Figure 11 The second cover 3 has two second connecting parts 31, and the support part 32 is placed between the two second connecting parts 31 and integrally injection molded.

[0064] Combination Figure 10 and Figure 11 The first cover 2 has two first connecting parts 21, and a second connecting part 31 is placed between the two first connecting parts 21, that is, the first connecting part 21, the second connecting part 31, and the hinge seat 12 (or support part 32) are arranged in sequence. The second connecting part 31 and the first connecting part 21 are arranged in sequence on both sides of the hinge seat 12. The support part 32 is located above or at the rear end of the hinge seat 12.

[0065] Both ends of the hinge seat 12 are provided with a first hinge shaft 14, the second connecting part 31 is provided with a second hinge shaft 33 and a first hinge groove 34, the first connecting part 21 is provided with a second hinge groove 24, the first hinge shaft 14 is inserted into the first hinge groove 34, and the second hinge shaft 33 is inserted into the second hinge groove 24, so that the first cover 2 and the second cover 3 are installed on the barrel 1;

[0066] Alternatively, a hinge rod can be inserted through the first connecting part 21, the second connecting part 31, and the hinge seat 12 to install the first cover 2 and the second cover 3 onto the barrel body 1. Specifically, the first connecting part 21, the second connecting part 31, and the hinge seat 12 are all provided with through holes. The hinge rod is inserted into the through hole, and the two ends of the hinge rod are connected to nuts by threads or by inserting pins. The nuts or pins abut against the outside of the first connecting part 21 to prevent the hinge rod from falling off.

[0067] The axis of the first hinge shaft 14 and the axis of the second hinge shaft 33 coincide, ensuring that when the first cover 2 and the second cover 3 rotate and open together, the first cover 2 and the second cover 3 can fit together, thus facilitating rotation.

[0068] The first hinge shaft 14 is provided with a first guide surface 141. One side of the first hinge groove 34 is connected to the end side of the second connecting part 31. The first hinge groove 34 is provided with a first anti-detachment part 35. The first anti-detachment part 35 is provided with a second guide surface 351. Through the sliding cooperation of the first guide surface 141 and the second guide surface 351, the first hinge shaft 14 is guided to slide into the first hinge groove 34, thereby realizing the installation of the second cover 3 onto the barrel 1.

[0069] The second hinge shaft 33 is provided with a third guide surface 331. One side of the second hinge groove 24 is connected to the end side of the first connecting part 21. A second anti-detachment part 25 is provided in the second hinge groove 24. A fourth guide surface 251 is provided on the second anti-detachment part 25. Through the sliding cooperation of the third guide surface 331 and the fourth guide surface 251, the second hinge shaft 33 is guided to slide into the second hinge groove 24, thereby realizing the installation of the first cover 2 onto the barrel 1.

[0070] Combination Figures 5-9 The driving device includes: a foot pedal device 5 and / or a lifting device 6, the foot pedal device 5 is installed on the barrel body 1 and connected to the second cover 3, and the lifting device 6 is installed on the second cover 3;

[0071] The foot pedal device 5 includes:

[0072] A foot pedal 51, the middle of which is hinged to the lower end of the barrel 1, and the front end of the foot pedal 51 extending beyond the lower end of the barrel 1, is for the user to step on; and

[0073] The connecting rod 52 is vertically installed at the rear end of the barrel 1, and the lower end of the connecting rod 52 is connected to the rear end of the foot pedal 51. The upper end of the connecting rod 52 extends into the hinge seat 12 and abuts against the second cover 3. The connecting rod 52 lifts the second cover 3, thereby allowing the second cover 3 to rotate and open around the hinge axis.

[0074] A further solution is that the second cover 3 is provided with a hook 36. By stepping on the front end of the foot pedal 51, the rear end of the foot pedal 51 causes the connecting rod 52 to move upward, thereby causing the connecting rod 52 to abut and push against the hook 36. The hook 36 drives the second cover 3 to rotate around the hinge.

[0075] When the foot leaves and releases the foot pedal 51, the connecting rod 52 moves downward under the weight of the foot pedal 51. The connecting rod 52 pulls the hook 36 to rotate the second cover 3. Under the weight of the second cover 3, the second cover 3 rotates and closes. The upper end of the connecting rod 52 can hook the hook of the hook 36, thereby restricting the rotation of the second cover 3.

[0076] The lifting device 6 includes a lifting band 61, which is installed in the mounting hole 37 of the second cover 3. The lifting band 61 is made of elastic material such as silicone or rubber. The lifting band 61 is provided with a lifting hole for lifting. The lower end of the lifting band 61 is provided with an anti-detachment protrusion and a limiting protrusion. The anti-detachment protrusion passes through the mounting hole 37 through its own elastic deformation. The anti-detachment protrusion and the limiting protrusion abut against the two sides of the mounting hole 37, that is, the anti-detachment protrusion and the limiting protrusion are respectively placed on the two sides of the second cover 3.
