Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and in particular to a folding and opening trash can. Background Technology

[0002] A trash can is a container used for collecting, storing, and temporarily storing garbage. It is widely used in homes, offices, public places, and other locations to facilitate the collection, sorting, and transportation of garbage. Some trash cans are lidless, while others have lids to help control odors and prevent insects from entering the can.

[0003] In-depth analysis of existing technologies:

[0004] - Difficult-to-clean areas: The hinges and connecting rods of traditional trash cans are exposed to the environment inside and outside the can for a long time, making them very easy for juices and dirt to penetrate, causing the mechanism to jam and bacteria to grow. Moreover, due to their complex structure and difficulty in disassembly, they are difficult to clean thoroughly.

[0005] - Limited effective disposal space: Traditional bin lid frames are usually designed to be quite large in order to secure garbage bags and install bin lids, which significantly encroaches on the effective disposal area of ​​the garbage bin opening and causes inconvenience to users when throwing garbage.

[0006] - The lid itself is a source of pollution: When the lid is opened and flipped up completely, it creates a large exposed surface that is easily contaminated by splashed juices or fallen dirt when users dispose of garbage.

[0007] To address the above problems, this utility model proposes a folding and opening trash can. Utility Model Content

[0008] The purpose of this invention is to solve the problems of inconvenience and unsanitary conditions of existing trash cans, and to propose a folding and opening trash can.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Foldable trash can, including:

[0011] The device comprises an opening and closing structure, an inner tub, and an inner tub frame. The opening and closing structure includes a folding structure, a support column, a lid, a bottom frame, a foot pedal, and a spring-loaded component. The folding structure includes a short rod and a long rod; one end of the short rod is connected to one end of another short rod, and the other end of the long rod is connected to the other end of the short rod; the upper end of the support column is connected to the long rod, and the lower end of the support column is connected to the bottom frame; the foot pedal is installed at the lower end of the support column, and the lid is installed at the upper end of the support column; the inner tub is placed in the center of the bottom frame, and the inner tub frame is fitted over the opening of the inner tub; the spring-loaded component is installed on the bottom frame and connected to the support column.

[0012] In one possible design, the folding structure further includes a joint plate and a joint fixing bolt. The short rod has bolt holes at both ends, a joint plate groove at one end of the short rod for installing the joint plate, and the two short rods are connected by the joint plate. The other end of the short rod has a long rod joint groove for installing the long rod joint plate.

[0013] In one possible design, the long rod has long rod joint plates at both ends, and post bolt grooves are opened at both ends. The long rod joint plates have bolt holes. The long rod joint plates are installed into the long rod joint grooves. The joint fixing bolts pass through the bolt holes of the short rod and the bolt holes of the long rod, so that the short rod and the long rod are fixed to each other and can be rotated and folded. The post bolt grooves are used to install post bolts.

[0014] In one possible design, the joint plate has bolt holes at both ends, and the two ends of the joint plate are respectively installed into the joint plate slots of the two short rods. The joint fixing bolt passes through the bolt holes of the short rods and the bolt holes of the joint plate, so that the short rods and the joint plate are fixed to each other, thereby enabling the two short rods to rotate and fold.

[0015] In one possible design, the support column is equipped with a top bolt, a bottom bolt, a lid buckle, a spring-loaded bolt, a foot pedal, and a support rod. It has a bag opening limiting groove, a lid limiting groove, and a support arc. The top bolt is installed into the top bolt groove, connecting and fixing the support column to the long rod, causing the long rod to open and close. The lid buckle is used to install the lid. The spring-loaded bolt is used to install a spring-loaded component. The foot pedal is used to install and fix the foot pedal. The support rod supports the paired support column, allowing the support column to open. The lid limiting groove cooperates with the lid buckle to limit the lid's loading and unloading angle. The bag limiting groove is used to fix the garbage bag opening, preventing the garbage bag from detaching from the bin opening. The support arc cooperates with the support rod to allow the support column to open.

[0016] In one possible design, the lid is used to close the inner barrel opening. The lid has a lid mounting hole and a lid limiting protrusion. The lid mounting hole is fitted onto the lid buckle to fix the lid to the support. The lid limiting protrusion and the lid limiting groove cooperate to limit the loading and unloading angle of the lid.

[0017] In one possible design, the bottom frame is provided with a bottom frame elastic buckle, a support post lower bolt groove, an inner bucket limiting protrusion, and a bottom frame stabilizing protrusion. The bottom frame elastic buckle is used to install elastic components, which connect the support post and the bottom frame to allow the support post to close automatically. The support post lower bolt groove is used to install the support post lower bolt, connecting and fixing the support post and the bottom frame. The inner bucket limiting protrusion is used to limit the installation position of the inner bucket, fixing the inner bucket in the center position of the bottom frame. The bottom frame stabilizing protrusion is used to prevent the bottom frame from tilting under the force of stepping, which would cause the trash can to tip over.

[0018] In one possible design, the foot pedal has foot pedal mounting grooves at both ends. The foot pedal mounting grooves are fitted onto the foot pedal bolts and fix the lower end of the support column to prevent the support column from detaching from the sides of the bottom frame. The foot pedal is used to transmit the force of the user's foot stepping, and through the lever principle, it drives the support column to open, thereby driving the folding structure to open. Two foot pedals are installed on both sides, allowing the user to open the trash can from any direction.

[0019] In one possible design, the inner bucket has a bag opening adapter groove, an inner bucket directional notch, and a handle hole at its opening. The bag opening adapter groove is used to fit garbage bags of different sizes, and the handle hole is used to lift the inner bucket for installation and removal.

[0020] In one possible design, the inner bucket frame has an inner bucket opening fixing groove and an inner bucket frame directional notch. The inner bucket frame fixing groove is fitted onto the inner bucket opening to clamp the garbage bag to prevent it from slipping off and to reinforce the inner bucket opening to prevent the opening from being pulled and deformed by heavy garbage when using small-sized garbage bags. The inner bucket frame directional notch is aligned with the inner bucket directional notch to determine the direction of the inner bucket frame installation.

[0021] In one possible design, the elastic component is not limited to rubber bands or springs; the elastic component is used to pull the support column, driving the opened support column to close.

[0022] In this application, the user installs the joint plate into the joint plate slot on the short rod, and the long rod joint plate into the long rod joint slot on the short rod. Then, the joint fixing bolts are installed into the respective bolt holes. The support column is installed onto the bottom frame according to the lower bolt groove of the support column, ensuring the support rod fits the support arc. Next, the long rod is installed onto the support column according to the upper bolt groove of the support column. The two ends of the elastic component are respectively installed onto the bottom frame elastic buckle and the support column elastic buckle. The foot pedal is installed onto the support column according to the foot pedal mounting groove aligned with the foot pedal bolt. The inner tub frame is aligned with the inner tub fixing bolt according to the inner tub frame directional notch. The user places the inner bucket into the notch at the opening of the inner bucket, steps on the foot pedal to open the opening and closing mechanism, places the inner bucket inside the opening and closing mechanism, inserts the garbage bag into the inner bucket through the opened folding mechanism, and places the garbage bag buckle on the upper end of the support column according to the bag opening limiting groove. The lid is then erected, and the lid mounting hole is aligned with the lid buckle and installed on the upper end of the support column. The foot pedal is released, and the folding mechanism is closed. If the user uses a small garbage bag, before placing the inner bucket, the garbage bag should first be placed on the bucket opening according to the bag opening fitting groove, then the inner bucket frame should be placed on the bucket opening, and then the inner bucket should be placed inside the opening and closing mechanism. Beneficial effects

[0023] In this utility model, the folding and opening trash can, through the coordinated design of the "folding and opening structure" and the "bag opening limiting groove", brings the following significant improvements:

[0024] Comprehensive improvement of hygiene standards:

[0025] The garbage bag can be fully unfolded through the limiting groove at the bag opening, forming an effective wrap and isolation around the inner wall of the garbage can opening, so that the waste mainly comes into contact with the easily replaceable garbage bag, rather than the permanent structure of the can body.

[0026] The lid hangs down naturally when opened, minimizing its surface area exposed to dirt. Furthermore, the lid design of this application is easy to disassemble, facilitating thorough cleaning by the user.

[0027] Optimize user experience and space utilization:

[0028] The folding structure components can be designed to be extremely slim, maximizing the usable space at the opening of the trash can.

[0029] The unique opening and closing mechanism allows users to open the trash can from any direction and throw away trash, making it more convenient to operate.

[0030] In this invention, the folding and opening trash can, through the bag opening adapter groove and the inner frame, enables the trash can to close effectively while being compatible with smaller-sized trash bags. This solves the problem that trash cans currently on the market that are compatible with different sized trash bags cannot close their openings and easily attract flies. Attached Figure Description
