Description

Technical Field

[0001] This utility model relates to the field of deodorization technology, specifically to a special vehicle deodorization circuit, device, and garbage truck. Background Technology

[0002] Sanitation vehicles are important tools for garbage collection and transportation and have been widely used in urban sanitation and garbage collection. However, garbage will produce odors during the collection and transportation process, mainly from harmful gases such as ammonia and hydrogen sulfide released during garbage decomposition. These gases are not only pungent and unpleasant, but also have adverse effects on human health and the environment.

[0003] In existing technologies, odor diffusion is usually reduced by sealing the vehicle compartment, manually spraying deodorizing agents, or regular cleaning. However, these methods have limitations. Sealing the vehicle compartment cannot completely eliminate odors, and manually spraying deodorizing agents is cumbersome and the effect is not lasting, making it difficult to meet the needs of efficient and automated deodorization in the garbage collection and transportation process. Utility Model Content

Firstly, it provides a special vehicle deodorization circuit, including a water pump drive circuit, a solenoid valve drive circuit, a cover plate drive circuit, a voltage source, a switch, and a time-delay relay. The voltage source is connected to the time-delay relay via the switch. The cover plate drive circuit, the solenoid valve drive circuit, and the water pump drive circuit are respectively connected to the voltage source via the switch. The solenoid valve drive circuit and the water pump drive circuit are connected in parallel. The solenoid valve drive circuit is used to regulate the pressure of the pipeline and the flow of the deodorizer. The voltage source is used to provide a stable DC power supply to the special vehicle deodorization circuit. The voltage of the DC power supply is any DC voltage capable of driving the special vehicle deodorization circuit. The time-delay relay is used to realize the delayed control of the device and sequentially switches the first contact and the second contact at predetermined times to control the closing of the solenoid valve and the water pump, and the opening of the cover plate, respectively.

[0005] Furthermore, the first contact of the time-delay relay is located between the solenoid valve drive circuit and the switch, and the second contact of the time-delay relay is located between the cover plate drive circuit and the switch.

[0007] Furthermore, when the cover is closed, pressing the switch activates the solenoid valve and electric water pump, generating pressure in the pipeline. The deodorant is then sprayed out through the nozzle. Continuously pressing the cover opening button keeps the water pump running. After the first delay, the solenoid valve and water pump automatically shut off, the deodorant spraying is complete, and the cover opens.

[0008] Furthermore, there are at least two nozzles.

[0022] Reference Figure 1-4 This utility model embodiment proposes a special vehicle deodorization circuit, including a water pump drive circuit, a solenoid valve drive circuit, a cover plate drive circuit, a voltage source, a switch, and a time delay relay. The voltage source is connected to the time delay relay through the switch. The cover plate drive circuit, the solenoid valve drive circuit, and the water pump drive circuit are respectively connected to the voltage source through the switch. The solenoid valve drive circuit and the water pump drive circuit are connected in parallel. The solenoid valve drive circuit is used to regulate the pressure of the pipeline and the flow of the deodorizer. The voltage source is used to provide a stable DC power supply for the special vehicle deodorization circuit. The voltage of the DC power supply is any DC voltage that can drive the special vehicle deodorization circuit to work. Preferably, it can be 12V or 24V. The specific DC voltage implementation scheme can be determined according to the selected water pump model. The time delay relay is used to realize the delay control of the device and sequentially switches the first contact and the second contact at a predetermined time to control the closing of the solenoid valve and the water pump and the opening of the cover plate, respectively.

[0023] This embodiment uses a time-delay relay to achieve automated timing control, ensuring that the solenoid valve and water pump work efficiently and collaboratively in a predetermined sequence, regulating pipeline pressure and stabilizing the delivery of deodorizing agent to improve the deodorization effect; by switching the time-delay contact, the solenoid valve and water pump are automatically shut off and the cover is opened, reducing manual operation, avoiding resource waste, improving the automation level and operating efficiency of the system, and meeting the high-efficiency and stable deodorization requirements during waste collection and transportation.

[0024] Furthermore, the first contact of the time-delay relay is located between the solenoid valve drive circuit and the switch, and the second contact of the time-delay relay is located between the cover plate drive circuit and the switch.

[0025] This embodiment uses the sequential switching of the first and second contacts of a time-delay relay to first control the solenoid valve and water pump, ensuring efficient spraying of the deodorizing agent to achieve the deodorizing effect.

The special vehicle deodorization circuit is one of the special vehicle deodorization circuits described above.

[0028] Furthermore, when the cover is closed, pressing the switch activates the solenoid valve and electric water pump, generating pressure in the pipeline. The deodorant is then sprayed out through the nozzle. Continuously pressing the cover opening button keeps the water pump running. After the first delay, the solenoid valve and water pump automatically shut off, the deodorant spraying is complete, and the cover opens.

[0029] This embodiment achieves automatic delivery and spraying of deodorant through the combination of deodorant tank, water pump, solenoid valve and nozzle. The deodorization circuit of the special vehicle provides precise delay control to ensure that the deodorant spraying process is efficient and stable.

[0032] This embodiment expands the deodorant spraying range and improves spraying uniformity and efficiency by screwing multiple interconnected nozzles onto the cover plate. The integrated design of the nozzles and cover plate facilitates installation and maintenance.
