Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and specifically discloses a ventilation-type direct-disposal trash can. Background Technology

[0002] A vacuum-sealed trash can is a smart trash can that uses vacuum technology to ensure the trash bag fits tightly against the inner wall of the can, thereby reducing air inside the bag, saving space, and preventing the trash bag from slipping off.

[0003] Existing exhaust-type direct-disposal trash cans have the exhaust device designed into the body of the can, which can achieve the function of the product. However, the volume of the trash can body is larger than the head. When the exhaust device is set in the body of the trash can, it will increase the cost. For example, an exhaust channel needs to be formed inside the trash can body, which will occupy the internal space of the trash can and reduce the trash capacity.

[0004] In terms of injection molds, it is more difficult and costly to improve a large injection molded part (the body of the trash can, such as the air inlet, air outlet, motor and fan mounting structure) than to improve a small injection molded part (the can head). In addition, it is more difficult to mold large-volume injection molded parts in one piece, resulting in a low yield rate. Utility Model Content

[0005] This utility model proposes a direct-disposal trash can with exhaust fan. By integrating the exhaust fan into the head of the trash can, the structure of the trash can body is simplified, the production cost of the trash can is reduced, the space utilization rate of the trash can is improved, and the yield rate of the trash can body injection molding production is increased.

[0006] This utility model is implemented as follows: a direct-disposal trash can with exhaust fan includes a trash can body and a can head. The can head is rotatably connected to the upper end of the trash can body via an external rotating shaft structure. A trash bag fixing mechanism is provided between the trash can body and the can head. An exhaust fan mechanism is provided inside the can head.

[0007] The garbage bag fixing mechanism includes a limiting groove located inside the upper part of the garbage can body. The upper part of the limiting groove is an outward expansion structure. The limiting groove is attached to the upper opening of the garbage can body through the outward expansion structure.

[0008] The exhaust mechanism includes a cavity inside the bin head, an air inlet pipe connected to the lower end face of the bin head communicating with the cavity, an electric fan matching the air inlet pipe installed inside the cavity, and an air passage pipe communicating with the body of the trash can connected to the lower end of the limiting groove, the air passage pipe being matched with the air inlet pipe.

[0009] As a preferred embodiment of the present invention, the lower end of the limiting groove is fixedly connected to an installation column located on one side of the air passage. A magnet is embedded in the upper end face of the installation column, and a Hall switch matching the magnet is embedded in the lower end face of the bin head. The Hall switch is electrically connected to an electric fan.

[0010] As a preferred embodiment of the exhaust-type direct-discharge trash can of this utility model, the inner wall of the limiting groove is provided with a bag-covering hole.

[0011] As a preferred embodiment of the present invention, the outer wall of the bin head is provided with a plurality of evenly distributed exhaust holes that communicate with the cavity.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A type of exhaust-type direct-disposal trash can includes a trash can body 1 and a can head 2. The can head 2 is rotatably connected to the upper end of the trash can body 1 through an external rotating shaft structure. A trash bag fixing mechanism is provided between the trash can body 1 and the can head 2. An exhaust mechanism is provided inside the can head 2.

[0024] The garbage bag fixing mechanism includes a limiting groove 3 located inside the upper part of the garbage can body 1. The upper part of the limiting groove 3 is an outward expansion structure. The limiting groove 3 is attached to the upper opening of the garbage can body through the outward expansion structure.

[0025] The ventilation mechanism includes a cavity 4 inside the bin head 2, an air inlet pipe 5 connected to the lower end of the bin head 2 and communicating with the cavity 4, an electric fan 6 matching the air inlet pipe 5 installed inside the cavity 4, and an air passage pipe 7 connected to the garbage bin body 1 and communicating with the inner lower end of the limiting groove 3. The air passage pipe 7 is matched with the air inlet pipe 5.

[0026] In this embodiment: During use, the upper opening of the garbage bag is fitted over the upper opening of the limiting groove 3, and the upper opening of the garbage bag is placed inside the limiting groove 3. Then, the bag body is passed through the limiting groove 3 and placed inside the garbage bin body 1. Then, the bin head 2 is rotated around the outer rotating shaft structure (the name and model of the outer rotating shaft structure is Sugatsune KSP series, which is a well-known and mature existing technology; its components and working principle will not be described in detail here. Simultaneously, the outer rotating shaft structure of the Sugatsune KSP series can self-lock the bin head 2) to make the bin head 2 cover the garbage bin body. The upper end of the bucket head 2 is tightly sealed to the two upper openings of the limiting groove 3, thereby sealing the bucket head 2 with the limiting groove 3 and the limiting groove 3 with the garbage can body 1. The garbage bag is fixed by the mutual cooperation between the lower end of the bucket head 2 and the upper opening of the limiting groove 3. At the same time, the lower end of the air inlet pipe 5 is sleeved on the upper outer wall of the air outlet pipe 7. Since the upper end of the air outlet pipe 7 extends into the interior of the air inlet pipe 5 and is tightly sealed to the air inlet pipe 5, the air outlet pipe 7 and the air inlet pipe 5 can be connected and sealed, so that the outer wall of the garbage bag and the inner wall of the garbage can body 1 are sealed.

[0027] Then the electric fan 6 starts. The electric fan 6 draws the air between the outer wall of the garbage bag and the inner wall of the garbage can 1 into the cavity 4 through the air intake pipe 5 and the air outlet pipe 7. Then it is discharged through multiple exhaust holes 11, so that a vacuum is formed between the outer wall of the garbage bag and the inner wall of the garbage can 1. The vacuum makes the outer wall of the garbage bag fit with the inner wall of the garbage can 1, thereby completing the installation and fixing of the garbage bag.

[0028] By installing the exhaust mechanism inside the bin head 2, the structure of the trash can body 1 is simplified, which facilitates the production of the trash can body 1, effectively reduces the production cost of the trash can body 1 and improves the yield rate of the injection molding production of the trash can body 1. At the same time, the simplified structure of the trash can body 1 can improve the space utilization rate of the trash can body 1.

[0029] As a technical optimization of this utility model, the lower end of the inner limit groove 3 is fixedly connected to the mounting column 8 located on one side of the air passage 7. The upper end face of the mounting column 8 is embedded with a magnet 9, and the lower end face of the barrel head 2 is embedded with a Hall switch that matches the magnet 9. The Hall switch is electrically connected to the electric fan 6.

[0030] In this embodiment: when the bucket head 2 is closed, the bucket head 2 causes the Hall switch to move closer to the magnet 9. When the distance between the two reaches the trigger threshold of the Hall element, the magnetic field of the magnet 9 acts on the Hall switch, triggering the Hall effect, which causes the output level of its internal integrated comparator (or Schmitt trigger) to flip (e.g., from high level to low level). This signal change is transmitted to the external control panel (built-in control processor, such as a microcontroller or dedicated IC), and the control panel then controls the electric fan 6 to start and begin ventilation.

[0031] The duration of the ventilation is precisely controlled by the preset program on the control panel (the default setting is nine seconds, which has been experimentally verified to effectively create negative pressure). After the time is up, the control panel automatically cuts off the power to the electric fan 6, and the ventilation stops. When the user opens the bucket head 2 again, the magnet 9 separates from the Hall switch, the magnetic field strength is lower than the release threshold, the Hall switch output signal is reset (restored to the initial level), and the system enters standby mode to prepare for the next trigger.

[0032] As a technical optimization of this utility model, the inner wall of the limiting groove 3 is provided with a bag-covering hole 10.

[0033] In this embodiment: Since the openings at the top of different garbage bags are of different sizes, and the openings at the top of some garbage bags are larger than the openings at the top of the limiting groove 3, when putting on the garbage bag, the excess part at the top of the garbage bag can be manually squeezed into the bag hole 10, and the excess part at the top of the garbage bag can be collected through the bag hole 10.

[0034] As a technical optimization of this utility model, the outer wall of the barrel head 2 is provided with a plurality of evenly distributed exhaust holes 11 that are connected to the cavity 4.

[0035] In this embodiment, air can be discharged from the cavity 4 through multiple exhaust holes 11.

[0036] As a technical optimization of this utility model, a one-way valve is installed inside the air intake pipe 5.

[0037] In this embodiment, the one-way valve enables air to flow in one direction, preventing external air from entering the space between the outer wall of the garbage bag and the inner wall of the garbage bin 1 through the air inlet pipe 5 and the air outlet pipe 7.

[0038] As a technical optimization of this utility model, the upper end of the air passage 7 extends into the interior of the air intake 5 and is tightly sealed to the air intake 5.

[0039] In this embodiment, the upper end of the air passage 7 extends into the interior of the air intake 5 and is tightly sealed to the air intake 5, thereby sealing the connection between the air passage 7 and the air intake 5.

[0040] The working principle and usage process of this utility model are as follows: In use, the upper opening of the garbage bag is fitted onto the upper opening of the limiting groove 3, and the upper opening of the garbage bag is placed inside the limiting groove 3. Then, the bag body portion passes through the limiting groove 3 and is placed inside the garbage bin body 1. Next, the bin head 2 is rotated around the outer pivot structure, causing the bin head 2 to cover the upper end of the garbage bin body 1, ensuring a tight seal between the lower end face of the bin head 2 and the two upper openings of the limiting groove 3. This seals the bin head 2 against the limiting groove 3. The groove 3 is sealed to the garbage can body 1, and the garbage bag is fixed by the cooperation between the lower end face of the can head 2 and the upper opening of the groove 3. At the same time, the lower end of the air inlet pipe 5 is sleeved to the upper outer wall of the air outlet pipe 7. Since the upper end of the air outlet pipe 7 extends into the interior of the air inlet pipe 5 and is tightly sealed to the air inlet pipe 5, the air outlet pipe 7 and the air inlet pipe 5 can be connected and sealed, so that the outer wall of the garbage bag and the inner wall of the garbage can body 1 are sealed.

[0041] When the lid 2 is closed, the lid 2 causes the Hall switch to move closer to the magnet 9. When the distance between the two reaches the trigger threshold of the Hall element, the magnetic field of the magnet 9 acts on the Hall switch, triggering the Hall effect, which causes the output level of the internal integrated comparator to flip. This signal change is transmitted to the external control panel, which then controls the electric fan 6 to start. The electric fan 6 draws the air between the outer wall of the garbage bag and the inner wall of the garbage bin 1 into the cavity 4 through the air intake pipe 5 and the air outlet pipe 7, and then discharges it through multiple exhaust holes 11, so that a vacuum is formed between the outer wall of the garbage bag and the inner wall of the garbage bin 1. The vacuum makes the outer wall of the garbage bag fit against the inner wall of the garbage bin 1, thereby completing the installation and fixation of the garbage bag.
