Description

Technical Field

[0001] This utility model relates to trash cans, specifically an odor-proof, sealed trash can. Background Technology

[0002] For example, utility model patent CN108423338A discloses a trash can with an odor-proof bag-clamping mechanism, including a lid and a body, as well as a head and an odor-proof bag-clamping mechanism. The head has an opening at both ends and can be fitted onto the upper part of the body. The lid is either installed at the upper opening of the head or on one side of the body. A sensor control circuit is installed on the head. The odor-proof bag-clamping mechanism includes a clamping rod, a support frame, a drive shaft, a synchronous belt, and a drive circuit. A support frame is installed on each side of the lower end of the head. The two ends of the drive shaft are connected to the same side of the two support frames, and a synchronous pulley is installed on each end of the drive shaft. A toothed pulley is installed on the other end of each support frame, corresponding to the synchronous pulley on the same support frame. The control terminal of the sensor control circuit is connected to the drive circuit of the odor-proof bag-clamping mechanism. When changing the trash bag, the bag opening can be tightened first, and then the clamping rod can be loosened to prevent the odor from spreading when changing the trash bag. This effectively isolates the odor of the trash and avoids bacterial contamination, achieving a double-layer odor-proof and antibacterial effect.

[0003] In the above structure, the bucket lid and the odor-proof bag clamping mechanism are two independent mechanisms that work together in conjunction. The use of two independent mechanisms makes the internal structure of the upper seat more complex and costly, and the height of the upper seat cannot be reduced. Utility Model Content

[0004] The purpose of this utility model is to provide a sealed trash can in which the lid and the sealing clamp of the trash bag are driven by the same set of drive mechanisms. When the drive mechanism rotates forward, the sealing clamp opens and the lid closes at the same time. When the drive mechanism rotates in reverse, the lid opens and the sealing clamp closes at the same time. Compared with the prior art, this utility model only requires one set of drive mechanisms and has the characteristics of compact structure, safety and hygiene.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A sealed trash can includes a can body and a base disposed at the upper end of the can body. The base has a trash inlet and a lid is provided at the trash inlet. The two ends of the lid are movably connected to the side wall of the trash inlet. A driving mechanism for the lid is provided inside the base. The lid is characterized in that: the lid includes a cover plate and a sealing plate, and the sealing plate and the cover plate form an included angle through a rounded corner and a bend. When the cover plate closes the trash inlet, the sealing plate is in an open state and close to the trash inlet or close to the can wall; when the cover plate is in a fully open state, the sealing plate is in a closed state below the trash inlet.

[0007] The sealing plate and the cover plate are an integral structure and are arranged in an L-shape. A bag holder is also provided inside the garbage disposal port. The upper port of the bag holder is located below the upper port of the garbage disposal port. The cover plate is located above the upper port of the bag holder or between the bag holder and the inner wall of the garbage disposal port. The sealing plate is located between the bag holder and the inner wall of the garbage disposal port or below the upper port of the bag holder.

[0008] The side wall of the bag holder has an clearance groove corresponding to the position of the sealing plate. When the sealing plate switches from the open state to the closed state, it will pass through the clearance groove.

[0009] The bottom of the seat is equipped with an air intake on the outside of the garbage disposal opening, and an air intake device is installed inside the seat at the position corresponding to the air intake.

[0010] The barrel body is equipped with a suction channel inside, the upper end of which is connected to the suction port, and the lower part of which is connected to the lower space of the barrel body.

[0011] An air outlet is provided on the side wall of the garbage disposal port corresponding to the side of the suction device.

[0012] The seat includes an upper seat and a lower seat. The garbage disposal opening is located on the upper seat, and the two ends of the bucket lid are pivotally connected to the side wall of the garbage disposal opening. The lower seat includes a base plate and a bag holder. The base plate is fixedly connected to the upper seat to position the bag holder inside the garbage disposal opening.

[0013] Both the waste disposal port and the bag holder are rectangular structures. At least one of the inner and outer walls of the waste disposal port and the bag holder has a receiving groove. When the cover or sealing plate is in the open state, it is placed in the receiving groove.

[0014] The receiving trough is connected to the waste disposal port via an avoidance trough.

[0015] The lid of this utility model consists of a cover plate and a sealing plate. The cover plate is equivalent to the lid of the existing structure, and the sealing plate is equivalent to the bag clamping rod of the existing structure. The cover plate and the sealing plate are controlled by the same driving device and are linked by the cover plate and the sealing plate at a certain angle to each other. When the cover plate closes the garbage disposal opening, the sealing plate is in the open state; when the cover plate is in the fully open state, the sealing plate is in the closed state below the garbage disposal opening. Compared with the existing technology, it eliminates a driving device and has the characteristics of compact structure, safety and hygiene. Attached Figure Description

[0026] like Figure 1-10 As shown, a sealed trash can includes a can body 1 and a base 2 disposed at the upper end of the can body. The base 2 has a trash inlet 21, and a can lid 3 is disposed at the trash inlet 21. The two ends of the can lid 3 are movably connected to the side walls of the trash inlet 21. A drive mechanism 4 for the can lid is disposed inside the base 2. The can lid 3 includes a cover plate 31 and a sealing plate 32. The sealing plate 32 and the cover plate 31 are an integral structure and are arranged in an L-shape. A bag holder 5 is also disposed inside the trash inlet 21. The upper end of the bag holder 5 is located below the upper end of the trash inlet 21. The cover plate 31 is located above the upper end of the bag holder 5 or between the bag holder 5 and the inner wall of the trash inlet 21. The sealing plate 32 is located between the bag holder 5 and the inner wall of the trash inlet 21 or below the upper end of the bag holder 5.

[0027] The seat 2 includes an upper seat 201 and a lower seat 202. The garbage disposal port 21 is located on the upper seat 201, and the two ends of the lid 3 are pivotally connected to the side wall of the garbage disposal port 21. The lower seat 202 includes a bottom plate 203 and a bag holder 5. The bottom plate 203 is fixedly connected to the upper seat 201 to position the bag holder 5 inside the garbage disposal port 21.

[0028] Both the waste disposal port 21 and the bag holder 5 are rectangular structures. At least one of the inner and outer walls of the waste disposal port 21 and the bag holder 5 has a receiving groove 204. When the cover plate 31 or the sealing plate 32 is in the open state, it is located in the receiving groove 204. The side wall of the bag holder 5 is provided with an avoidance groove 51 corresponding to the position of the sealing plate 32. The receiving groove 204 is connected to the waste disposal port 21 through the avoidance groove 51.

[0029] The bottom of the base 2 is provided with an air inlet 22 outside the garbage disposal port 21, and an air suction device 6 is provided inside the base 2 at the position corresponding to the air suction port 22; the inside of the bin 1 is provided with an air suction channel, the upper end of which is connected to the air suction port 22, and the lower part of which is connected to the lower space of the bin 1; an air outlet 23 is provided on the side wall of the garbage disposal port 21 corresponding to the side of the air suction device 6.

[0030] This utility model integrates the cover plate and the sealing plate into an L-shaped structure. When the cover plate 31 closes the garbage disposal opening, it is positioned above the upper end of the bag holder 5, and the sealing plate 32 is located between the bag holder 5 and the inner wall of the garbage disposal opening 21. When the cover plate 31 switches from the closed state to the open state, the sealing plate 32 switches from the open state to the closed state. When the sealing plate 32 switches from the open state to the closed state, it passes through the clearance groove 51 of the bag holder 5 and clamps the garbage bag below the garbage disposal opening 21. This ensures that no odor can be smelled inside the bin when disposing of garbage. At the same time, the garbage is temporarily placed at the opening of the clamped garbage bag, and the garbage is surrounded by the garbage bag and does not contaminate the inner wall. At the same time, the garbage inside the bin is not visible. After the garbage is disposed of, the cover plate closes again and the sealing plate opens simultaneously. The garbage that was just disposed of falls into the bin automatically under the action of gravity.

[0031] This invention requires only one set of drive devices to control the cover plate and the sealing plate simultaneously. Compared with the existing method where two sets of drive devices control the cover plate and the sealing plate independently, this invention is more compact in structure. As a result, the height and weight of the seat will not be too high or too heavy.

[0032] In addition, this utility model is equipped with a suction device inside the seat. When the sealing plate clamps the garbage bag and then reopens it during use, the garbage bag is very light and the garbage is also very light, so the garbage bag cannot open automatically by its own weight. When the suction device is turned on, air is drawn into the space under the bin through the air inlet and air channel. The negative pressure is used to reopen the contracted bag opening, so that the garbage can fall into the bin smoothly. This utility model has the characteristics of compact structure, safety and hygiene.

[0033] The lid 3 of this utility model is not limited to an L-shaped structure. The sealing plate 32 and the lid 31 can also form an angle through a rounded corner or other angles. The lid 3 can be rotated by controlling the rotation angle of the lid 3 through the drive mechanism to ensure that the lid 31 can close the upper end of the garbage disposal opening or that the sealing plate 32 can clamp the garbage bag at the lower end of the garbage disposal opening.
