[0007] Garbage removal and cleaning of roads and streets using the usual methods, which is the same as sweeping by a sweeper, has disadvantages and problems such as:

[0008] High volume of dust in manual sweeping, low speed of cleaning, thread of sweeper’s health (breath of dust), though condition for pick up some trashes, exhausting 8 hours continuous sweeping, thread of sharp trash, thread of acidic and microbial trash, high volume of trash after every festival and Carnival, and also conventional vacuum cleaners are not able to collect waste from industrial workshops due to their high density.

[0009] In order to reduce these problems, in recent years, various apparatuses have been designed and built for cleaning urban roads. Over time, these apparatuses have made more improvements by adding features. The things that have always been among the concerns of improving the quality of these apparatuses and many efforts have been made to improve them are: how to position the operator to use the apparatus, how to connect the filters and ease of installation and removal, the shell of the apparatus for better access to the inside of the apparatus and easier maintenance and maintenance, using the wind output for purposes such as cooling and using it as filter and blower cleaning and things like that.

[0010] Despite all the efforts that have been made to solve the problems with these apparatuses, there are still many problems. Existing apparatuses do not allow the operator to sit, stand, and walk simultaneously. Moreover, the shells have been designed so that different doors cannot be installed on them, resulting in difficulty accessing the internal equipment and difficulty maintaining and repairing them. One of the other problems with these apparatuses that has not been solved so far is the inability to easily move the apparatus to the top of the truck and the lack of convenience in emptying the trash can. Also, for heavy wastes whose suction is problematic, if the operator does not pay attention to their suction, it may remain suspended in the pipe path after suction. This may lead to blockage of the path.

[0011] This proposed embodiment is intended to provide a city sweeper that can be used by an operator to increase the speed, ease to use, and efficiency of cleaning city streets. Among the components of this apparatus are suction section means, multifaceted shells, seats, and steering wheels. The operator has the ability to sit on a chair, stand on the steps of the machine and walk with the machine to clean the passages with the help of the machine. Additionally, the apparatus has a multifaceted shell with multiple doors installed to allow for easy maintenance and use of different features. Creating an output shaft from the drive motor to start secondary apparatuses.Solution to Problem

[0012] For the given problem, a street vacuum cleaner with a changeable diameter crevice nozzle [Figure 1] has been designed, which can be used by an operator to clean urban roads in a shorter, easier and cleaner time, and to transport it. This apparatus is composed of various parts and systems, which include suction section means, polyhedral shell "1" along with seat and steering wheel, angle detection sensor, output shaft from drive motor "2" for starting secondary apparatuses, active noise control technology, intelligent suction control mechanism, a crevice nozzle with a changeable diameter "3", a SIM card for communication between the apparatus, the operator, and the owner through a dedicated application, a dispatching system for acquiring data from individual vacuum cleaners, including their precise location and cleaning status, LCDscreens, and a robust generator as a secondary apparatus for producing alternating current (AC) power.

[0013] Suction Section Means includes the air entering the suction pipe to the air leaving the suction. This section includes the fan and the suction chamber, filtration and separation of waste from the air by emptying the waste in the bucket and exiting the air from the suction. The flow path in this system comprises handle and hose, trash can, flat screen filter, cylindrical filter, connecting pipes, housing inlet, impeller, fan outlet, engine cooling and manifold feeding and air discharge to the outside environment. In this apparatus, suction is possible both through the hose pipe and through the bottom of the sweeper (with the help of a sweeper). This apparatus includes an Anti-sticking system in the filter section to prevent the sticking of plastic and leaves and also it has a filter shaker and reverse airflow for the cleaning filter.

[0014] The designed shell is a polyhedral shell "1" [Figure 2] on which a seat is installed and the steering wheel is in front of it. In this machine, the operator can sit on a chair, stand on the machine steps, and walk with the machine. This geometric shell is designed multifaceted, with different doors installed on it. Multiple doors provide easy access to internal equipment and convenience for repairs and maintenance. In addition, it allows the use of various apparatus capabilities due to its versatility.

[0015] The handle is equipped with an angle detection sensor, which for when the apparatus wants to turn to the sides, by detecting the rotation angle of the steering wheel and by PWM, drive motors are fed with a different speed to turn around, and this makes bypassing easy.

[0016] An output shaft "2" [Figure 3] is taken from the drive motor and when the fan engagement is taken from the drive motor by the electric clutch, it starts working and by default the winch is closed on it, and it can even be used to start the water pump, sprayer, and apparatuses of this form can be used from the output shaft "2". This secondary apparatus can be separately connected to the sweeper output and its shaft, or it can be a part of the apparatus itself, which is used when needed by releasing the electric clutch connected to the fan.

[0017] A snow brush that clears snow from the passways is a mechanism that is attached to the system. The fan and its output air are used to drive the pneumatic hydro-turbine and power the snow brush.

[0018] When a piece of debris gets stuck in any part of the suction system, it will block the path, create a vacuum, and immediately rupture the trash bin. The vacuum breaker check valves are used with the suction system to prevent them from rupturing. The vacuum breaker check valves open at very low positive pressure and would take the air into the tank. By using this system, possible damage to the vacuum cleaner is avoided.

[0019] The proposed apparatus is comprising a cleaning apparatus with integrated active noise control technology [Figure 4], By implementing this feature, the apparatus effectively minimizes the emitted sound during operation, resulting in a quieter and more pleasant environment for both the operator and the nearby community. The Active Noise Control system receives a reference signal from the tachometer (read the motor round) and a load speaker to cancel out noise and dampen unwanted noise from the engine, motor, and other rotating parts. With an error signal from the microphone and feedback, it corrects the canceling noise. The inclusion of active noise control ensures cleaning performance without contributing to unnecessary noise pollution. Consequently, this technologically advanced system is highly suitable for deployment in residential areas, busy streets, and other noise-sensitive locations.

[0020] Another described feature of the present apparatus involves a power-saving functionality implemented through a series of intelligent suction adjustments. In the power-saving mode, the vacuum cleaner's fan operates at the lowest suction mode. However, when waste within the tube is detected using infrared sensors, the suction mode is automatically adjusted to a medium level. Additionally, another sensor is utilized to identify a significant quantity or heavy waste, prompting the system to switch to the maximum suction power mode. This intelligent suction control mechanism serves to optimize the apparatus's operating time, enhancing its efficiency apparatuses.

[0021] This apparatus has a crevice nozzle with a changeable diameter "3", which the operator can adjust for bulky or small and dense waste [Figure 5]. This nozzleconsists of a flexible nozzle shoe "4", two linear motors "5", two L rod clevis ends "6", two connecting rods "7", two double-ended hinge rods (with one degree of freedom) "8", and a structure ring "9". When linear motors "5" run and L rod clevis ends "6" come out, the connecting rods "7" turn the double-ended hinge rods "8" inward, and the flexible nozzle shoe "4" crumples, and the inlet of it gets smaller.

[0022] The disclosed urban vacuum cleaner comprises a SIM card that facilitates communication between the apparatus, the operator, and the owner through a dedicated application (App). The application provides valuable information regarding the apparatus's battery charge status, battery life, recommended replacement times for parts, and bin capacity. Furthermore, the application incorporates a machine lock and anti-theft system. This system extends beyond simply locking the wheels; leveraging the capabilities of the SIM card, it also enables location tracking and reporting via GPS, thereby notifying any change in location and providing real-time location updates.

[0023] An enhanced feature of this apparatus could be a dispatching system that acquires data from individual vacuum cleaners, including their precise location and cleaning status. This data can be leveraged to optimize the routes taken by the vacuum cleaners and assign them to specific areas requiring cleaning. The dispatching system is also capable of transmitting real-time updates to each vacuum cleaner, furnishing them with instructions regarding the designated destinations and tasks to be accomplished. As a result, operational efficiency is improved, and the time required for cleaning a particular area is reduced. Additionally, the vacuum cleaners feature LCD screens that display pertinent information such as the ongoing task, upcoming tasks, as well as any alerts or notifications.

[0024] Included as an additional feature in the gasoline engine-operated model is an optional secondary apparatus, which comprises a robust generator. This generator is capable of producing alternating current (AC) power, serving external consumers and ensuring its versatility for a wide range of applications. For instance, it can be employed in constructing urban pathways, municipal gardening, rescue operations, carnivals, disinfection of municipal waste bins, and other similar scenarios.Advantageous Effects of Invention

[0025] This apparatus has created benefits for the operator and the consumer that are new and did not exist in previous inventions. These benefits include:

[0026] - Unlike previous inventions, this apparatus introduces new benefits for both the operator and the consumer. It allows for the activation of various apparatuses such as water pumps, sprayers, and winches by utilizing the output shaft from the drive motor.

[0027] - By using this nozzle, if the waste is bulky, the nozzle is at its maximum cross-sectional area, and if the waste is dense and more pressure is needed to suction them, the cross-sectional area of the nozzle is reduced to increase the suction pressure. In fact, in similar apparatuses, this is possible by changing the nozzle, but in this invention, the nozzle has the ability to change the cross section.

[0028] - Versatility in Operation: The operator has the freedom to sit, stand, or walk while operating the apparatus, providing flexibility and comfort during use.

[0029] - Easy Maintenance and Access: The geometric shell design of the apparatus facilitates easy access to internal components, simplifying maintenance tasks and allowing for optional uses.Brief Description of DrawingsFig.1

[0041] The apparatus requires an operator to operate it. The operator has multiple options for maneuvering the apparatus. They can either clean roads and streets while sitting on a chair attached to the machine, standing on the steps of the machine, or simply walk alongside it. Once the operator turns on the motor, the suction mechanism activates, allowing the operator to start collecting waste. The angle detection sensor, which is installed on the handle, plays a crucial role in theoperation. It enables the apparatus's drive motors to receive variable revolutions through Pulse Width Modulation (PWM). This feature facilitates easy and fast maneuvering of the apparatus. The drive motor is equipped with an output shaft that serves multiple purposes. When the fan is not engaged in the suction process, the output shaft can be utilized to power other secondary apparatuses. For example, it can start the water pump, sprayer, winch, and similar auxiliary equipment. By pressing a button and adjusting the nozzle cross-section, the user can prepare the nozzle for bulky or dense waste. By leveraging the diverse capabilities of the apparatus, the operator can efficiently clean various types of surfaces, including roads, streets, and passages in urban and rural areas. Additionally, its versatility allows for application in a wide range of locations such as commercial centers, airports, railway and subway stations, as well as educational, research, and military centers. This implementation method empowers the operator to utilize the apparatus's features effectively, ensuring thorough cleaning while offering flexibility and ease of use.Industrial Applicability

[0042] The proposed urban vacuum cleaner is an apparatus that can be used in all passages, streets and urban and rural contexts, all commercial centers, airports, railway and subway stations, as well as educational, research and military centers.
