[0002] In densely populated metropolitan areas, waste disposal is a major headache. Common practices include collecting waste and sending it to landfills or incinerating it. However, both methods create environmental problems. Stopping overconsumption can further reduce landfill saturation. Waste disposal in landfills not only pollutes groundwater and produces foul odors, but also means that landfill space in many cities is dwindling. Incineration inevitably produces toxic gases that harm organisms. Therefore, centralized transportation and treatment are necessary. Existing garbage trucks are not fully functional and have a strong odor and significant bacterial growth.

[0003] For example, Chinese utility model application number 201610286001.6 proposes a water-collecting garbage bin with the function of eliminating odors inside a vehicle. In use, the telescopic rod switch is turned on, the telescopic rod lifts up the garbage bin, the back cover is opened and the garbage is emptied, then the fan switch is turned on, the exhaust fan draws air outwards, and then the ultraviolet sterilization lamp switch is turned on, the ultraviolet sterilization lamp sterilizes the inside of the bin, and the activated carbon plate removes the odor inside the garbage bin. However, since there are many kinds of garbage in the bin and they are mixed, directly sterilizing or removing odors will affect the effect.

[0004] Therefore, this utility model proposes an odor purification device for garbage collection. Utility Model Content

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-6 In this embodiment of the utility model, an odor purification device for garbage collection includes a garbage truck 1. The garbage truck 1 is characterized by: a garbage bin 2 installed on it; a disposal opening 3 at the top of the garbage bin 2 for disposing of garbage; a discharge door 4 and a discharge trough 5 installed on the right side wall of the garbage bin 2; the discharge door 4 discharges garbage, and the discharge trough 5 discharges liquid; an exhaust fan 15 is installed on the inner top wall of the garbage bin 2; an exhaust pipe 6 is connected to the output end of the exhaust fan 15; the exhaust pipe 6 discharges gas from the garbage bin 2 through the output of the exhaust fan 15; and an isolation plate 8 is installed at the lower middle part of the inner wall of the garbage bin 2. A guide groove 9 is installed on the right side of the bin 2. The guide groove 9 can guide the liquid in the garbage to the storage chamber. A vertical plate 11 is installed on the left side of the top of the partition plate 8. A reciprocating screw 7 is connected between the vertical plate 11 and the right inner wall of the garbage bin 2. A moving plate 10 is connected to the surface of the reciprocating screw 7. The moving plate 10 can move left and right by rotating the reciprocating screw 7. The vertical plate 11 and the left inner wall of the garbage bin 2 form a storage chamber. A drive structure and an exhaust fan 14 are installed in the storage chamber. The drive structure can drive the reciprocating screw 7 to rotate. The exhaust fan 14 and the ventilation fan 15 work together to allow the gas inside the garbage bin 2 to circulate and reduce the generation of odor inside the garbage bin 2.

[0024] In this embodiment of the utility model, the driving structure includes a motor 12, a connecting shaft 13, a worm gear 16, and a worm 17. The motor 12 is connected to the top of the isolation plate 8. The right end of the connecting shaft 13 is fixedly connected to the output end of the motor 12, and the worm 17 is sleeved on the surface of the connecting shaft 13. The worm gear is connected to the left end of the reciprocating screw 7. The power of the motor 12 can be transmitted to the connecting shaft 13 through the output end, causing the connecting shaft 13 to rotate. The worm 17 also rotates with the connecting shaft 13. The left end of the reciprocating screw 7 passes through the vertical plate 11 and is rotatably connected to the left inner wall of the garbage bin 2, providing support and constraint for the rotational movement of the reciprocating screw 7 and ensuring its stable operation. The left end of the reciprocating screw 7 is connected to the worm gear, which meshes with the worm 17 for transmission. The moving plate 10 is located on the right side of the vertical plate 11 and is threadedly connected to the reciprocating screw 7. The rotation of the reciprocating screw 7 can drive the moving plate 10 to move left and right.

[0025] When in use, start the motor 12. The motor 12 drives the connecting shaft 13 to rotate. The worm gear 17 rotates together with the connecting shaft 13. The worm gear 17 drives the worm wheel 16 to rotate, which in turn drives the reciprocating screw 7 to rotate. At this time, the moving plate 10 moves left and right through the reciprocating screw 7. When there is garbage in the garbage bin 2, the moving plate 10 can be moved to the right to squeeze the garbage to the right end of the isolation plate 8, thereby squeezing out the liquid in the garbage. At the same time, it can save the storage space in the garbage bin 2 and facilitate discharge.

[0026] The exhaust fan 14 is installed above the storage cavity. The exhaust fan inlet pipe passes through the vertical plate 11 and is located inside the garbage bin 2. The exhaust fan 14 is located at a relatively high position, which can more effectively extract gas. The exhaust fan 15 is connected to the exhaust pipe 6 on the right side. The right end of the exhaust pipe 6 passes through the right side wall of the garbage bin 2. The inner wall of the exhaust pipe 6 is provided with an activated carbon layer. Activated carbon has good adsorption performance. The activated carbon layer on the inner wall of the exhaust pipe 6 can adsorb odors and harmful substances in the exhaust gas.

[0027] Simultaneously, the exhaust fan 14 and the ventilator 15 are activated. Outside air enters the trash can 2 through the exhaust fan 14. Since the exhaust fan 14 is located at a relatively high position, it can fully fill the trash can 2 with outside air. At the same time, the ventilator 15 discharges the air in the trash can 2 outside through the exhaust pipe 6, realizing air circulation in the trash can 2 and reducing the generation of odors. The activated carbon layer set on the inner wall of the exhaust pipe 6 can also adsorb odors and harmful substances in the discharged air, avoiding pollution to the external environment when discharged.

[0028] A storage cavity is formed between the partition plate 8 and the bottom inner wall of the garbage bin 2. The storage cavity can be used to store liquid in the garbage. Multiple filter holes are opened on the right side of the partition plate 8. The liquid in the garbage enters the storage cavity through the filter holes. The filter holes pass through the partition plate 8 and the top wall of the guide groove 9 in sequence. The bottom wall of the guide groove 9 is sloping. The sloping shape facilitates the flow of liquid and at the same time prevents the liquid in the storage cavity from flowing back to the top of the partition plate 8.

[0029] When the moving plate 10 moves the garbage to the right end of the isolation plate 8, the liquid in the garbage falls into the guide groove 9 through the filter holes, and then flows into the storage chamber through the guide groove 9, realizing solid-liquid separation of garbage, reducing the generation of odor, and the liquid concentrated in the storage chamber is finally discharged and treated by the discharge groove 5.

[0030] When using this device, garbage is disposed of through the disposal port 3 at the top of garbage bin 2. Once the garbage enters garbage bin 2, motor 12 is activated. Motor 12 drives the connecting shaft 13 to rotate, thereby rotating the worm gear 17. The worm gear 17 drives the worm wheel 16 to rotate, which in turn drives the reciprocating screw 7 to rotate. When the reciprocating screw 7 rotates, the moving plate 10, which is threadedly connected to it, moves left and right. When the moving plate 10 moves to the right, it squeezes the garbage, pushing it to the right end of the separator plate 8, thus squeezing out the liquid from the garbage. This not only saves space inside garbage bin 2 but also facilitates subsequent processing.

[0031] Meanwhile, the exhaust fan 14 is installed above the storage cavity, and its air inlet pipe passes through the vertical plate 11 and is located inside the garbage bin 2. It can draw outside air into the garbage bin 2. The exhaust pipe 6 connected to the right side of the exhaust fan 15 passes through the right side wall of the garbage bin 2. After the exhaust fan 14 and the exhaust fan 15 are started, outside air enters the garbage bin 2, and the air inside the bin is discharged through the exhaust pipe 6, realizing air circulation and reducing odor generation. The activated carbon layer on the inner wall of the exhaust pipe 6 can adsorb odors and harmful substances in the discharged air, avoiding pollution of the external environment.

[0032] The storage cavity formed by the partition plate 8 and the bottom inner wall of the garbage bin 2 is used to store liquid. Multiple filter holes on the right side of the partition plate 8 allow the liquid in the garbage to pass through the partition plate 8 and the top wall of the guide channel 9 in sequence, and enter the guide channel 9. The bottom wall of the guide channel 9 is sloping, which facilitates the flow of liquid to the storage cavity and prevents liquid backflow. When the moving plate 10 pushes the garbage to the right end of the partition plate 8, the liquid in the garbage falls through the filter holes into the guide channel 9, and then flows into the storage cavity, realizing solid-liquid separation of the garbage, reducing odor. Finally, the liquid in the storage cavity is discharged and treated by the discharge channel 5.

[0033] For example, in the actual garbage collection process, when the garbage truck 1 is full of garbage and is driving, this device can be activated to squeeze the garbage and purify the odor. After arriving at the destination, the liquid in the storage chamber is then centrally treated. This design can improve the efficiency and environmental friendliness of garbage collection.
