[0002] Lecture halls, with their unique seating arrangement, are widely used in large educational institutions and lecture venues. This design not only provides excellent sightlines, allowing each audience member to clearly see the speaker, but also accommodates a large number of people due to its sloping seating layout.

[0003] After each use, the floor of the lecture hall inevitably accumulates some waste paper, scraps of paper, and other trash. Therefore, it needs to be cleaned regularly. Maintaining classroom hygiene is not only a measure to protect health, but also a key to improving learning efficiency and experience.

[0004] However, the special structure of lecture halls makes it difficult for conventional robotic vacuum cleaners to perform cleaning tasks. Currently, cleaning is mainly done manually. The cleaning work usually starts from one end of each row of steps and cleans along the length of the steps, or starts from the highest step and cleans in staggered order. Both of these methods require a lot of time and labor. Therefore, developing a device that can efficiently clean the floor of lecture halls has become a common pursuit for those skilled in the art.

However, this is only for illustrative purposes and is not intended to limit this utility model to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0028] The present invention provides a tiered classroom cleaning device in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0029] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0030] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0031] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0032] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0033] like Figures 1 to 5 As shown, an embodiment of this utility model provides a tiered classroom cleaning device, including a blowing mechanism. The blowing mechanism includes multiple air nozzles 1 and an air pump 6. The multiple air nozzles 1 are disposed on each step 2, spaced apart along the length of the step 2 and facing the horizontal step surface 3 between the two seat legs of the seats 5 on the step 2. There is a gap between the back of the front seat 5 and the vertical step surface 4 of the step 2 where the rear seat 5 is located. The exhaust end of the air pump 6 is connected to each air nozzle 1 through an air supply pipe. Using the above-described tiered classroom cleaning device, the air pump 6 is connected to each air nozzle 1 through an air supply pipe. The airflow generated by the air pump blows the garbage away from the horizontal step surface 3, starting from the highest point of the tier and gradually sweeping the garbage to the next lower step 2 until reaching the lowest point. Finally, cleaning personnel can collect the garbage at the lowest point in one go. This not only greatly improves cleaning efficiency but also significantly reduces the input of human resources. It should be noted that the tiered classroom cleaning device provided in this embodiment is only suitable for waste paper and other ordinary waste of similar size. This type of ordinary waste can be blown away by the airflow generated by the nozzle 1, but it is not easily stirred up, so that the waste can be smoothly blown to the bottom of the tier. However, it is not advantageous for handling fine particulate waste such as dust. In addition, the gap between the back of the front seat 5 and the vertical step surface 4 of the step 2 where the rear seat 5 is located should be larger than the size of the aforementioned ordinary waste to ensure that the waste can smoothly reach the bottom of the tier.

[0034] Furthermore, the nozzle 1 can be elongated and arranged horizontally to expand the jet range.

[0035] like Figure 3 As shown, the gas supply pipeline includes a first gas supply pipe 7, a second gas supply pipe 8, and a third gas supply pipe 9. The first gas supply pipe 7 is located on each step 2 and connected to multiple nozzles 1 on that step 2. The second gas supply pipe 8 is connected to each first gas supply pipe 7. The third gas supply pipe 9 connects the multiple second gas supply pipes 8 and the exhaust end of the air pump 6. When the air pump 6 starts, the airflow first enters the third gas supply pipe 9, then enters the second gas supply pipe 8, and finally enters the first gas supply pipe 7, where it is discharged through the multiple nozzles 1. Of course, as long as the exhaust end of the air pump 6 can be connected to each nozzle 1, there are no particular restrictions on the specific structural form of the gas supply pipeline.

[0036] like Figure 2 and Figure 3As shown, the tiered classroom cleaning device also includes a spraying mechanism, which comprises multiple spray nozzles 10 and a water tank 11. The multiple spray nozzles 10 are located on each step 2, spaced apart along the length of the step 2 and facing the horizontal step surface 3 between the legs of the two seats 5 on the step 2. The water tank 11 is connected to each spray nozzle 10 via a water pump 12 and a water supply pipeline. By adding the spraying mechanism, when the sweeping mechanism is running, the water pump 12 of the spraying mechanism is activated, using the power provided by the water pump 12 to spray water or disinfectant in the water tank 11 into the horizontal step surface 3 of the step 2 in the form of water mist at the spray nozzles 10, reducing dust generated during the sweeping process of the air jet nozzles 1. If the water tank 11 contains disinfectant, it can not only suppress dust but also disinfect. Of course, to improve the dust suppression and / or disinfection effects, in this embodiment, the spray nozzles 10 on each step 2 are positioned vertically higher than the air jet nozzles 1. This setup effectively creates a water mist barrier above the blowing range of nozzle 1, further reducing dust generated during the blowing process. It should be noted that the water or disinfectant sprayed by the spray mechanism is only intended to reduce dust generated during the blowing process of nozzle 1. Therefore, the amount of water or disinfectant sprayed does not need to be large, and the water pump 12 should be turned off promptly when the required amount of spray is reached to avoid excessive water flow on the ground.

[0037] like Figures 1 to 3 As shown, the water supply pipeline includes a first water supply pipe 13, a second water supply pipe 14, and a third water supply pipe 15. The first water supply pipe 13 is located on each step 2 and connected to multiple spray nozzles 10 on that step 2. The second water supply pipe 14 is connected to each first water supply pipe 13. The third water supply pipe 15 connects the multiple second water supply pipes 14 and the drain end of the water pump 12. When the water pump 12 starts, the water first enters the third water supply pipe 15, then the second water supply pipe 14, and finally the first water supply pipe 13, where it is sprayed out as a mist by the multiple spray nozzles 10. Of course, as long as the water tank 11 can be connected to each spray nozzle 10, there are no particular restrictions on the specific structural form of the water supply pipeline.

[0038] like Figure 3 As shown, the vertical step surface 4 of the step 2 is recessed with mounting groove 16 and mounting groove 27, and multiple air nozzles 1 and multiple spray nozzles 10 are respectively embedded in mounting groove 16 and mounting groove 27. By embedding the air nozzles 1 and spray nozzles 10 into mounting groove 16 and mounting groove 27 respectively, this concealed design can prevent the air nozzles 1 and spray nozzles 10 from being damaged by accidental external impacts, thus protecting the air nozzles 1 and spray nozzles 10. At the same time, it does not occupy the space of the horizontal step surface 3 of the step 2, making it convenient for the installation of the seat 5.

[0039] like Figure 1 and Figure 5As shown, each air supply pipe 28 is equipped with a solenoid valve 18. The tiered classroom cleaning device also includes a timer switch 20, which is configured to individually control the opening and closing of each solenoid valve 18. By using the timer switch 20 to control the opening and closing of the solenoid valves 18, the opening and closing of the air nozzles 1 on each step 2 can be controlled independently. When cleaning the tiered classroom, the air nozzles 1 on the upper step 2 can be opened first, while the air nozzles 1 on the lower step 2 can be closed. In this way, the airflow generated by the air pump 6 can be concentrated from the air nozzles 1 on the upper step 2, thereby better blowing the garbage on the upper step 2 onto the lower step 2, until all the garbage is blown away from the steps 2. Using this method of independently controlling the opening and closing of the air nozzles 1 on each step 2, the airflow generated by the air pump 6 can be concentrated on a certain step 2, thus achieving a better cleaning effect.

[0040] like Figure 1 and Figure 5 As shown, each water pipe 2 14 is equipped with a solenoid valve 2 19, and the timer switch 20 is configured to individually control the opening and closing of each solenoid valve 2 19. By using the timer switch 20 to control the opening and closing of the solenoid valve 2 19, the opening and closing of the spray nozzles 10 on each step 2 can be controlled independently. When cleaning the lecture hall, the spray nozzles 10 on the upper step 2 can be controlled to open first, and the spray nozzles 10 on the lower step 2 can be controlled to close. In this way, the water flow generated by the water pump 12 can be concentrated and sprayed out in the form of water mist from the spray nozzles 10 on the upper step 2, thereby achieving a better dust suppression effect. By using this method of independently controlling the opening and closing of the spray nozzles 10 on each step 2, the water flow generated by the water pump 12 can be concentrated and sprayed into the form of water mist onto a certain step 2, thereby achieving a better dust suppression effect.

[0041] like Figure 4 and Figure 5As shown, in order to achieve the purpose of automatically controlling the solenoid valves 18 and 19 on each step of the tiered classroom to open and close sequentially according to time, in this exemplary embodiment, the tiered classroom cleaning device further includes a control component. The control component includes a bracket 21, a lead screw 22, a motor 23, a first contact 24, multiple second contacts 25, and a power supply 26. The lead screw 22 is rotatably mounted on the bracket 21; the motor 23 is electrically connected to the output terminal of the time control switch 20 via a wire and is used to drive the lead screw 22 to rotate; the first contact 24 is threadedly connected to the lead screw 22 and... The bracket 21 is slidably in contact along the first direction; multiple contacts 25 are arranged at intervals along the first direction and are elastically deformable in a second direction perpendicular to the first direction. The number of contacts 25 corresponds to the number of solenoid valves 18 and 19. Each contact 25 is electrically connected to solenoid valve 18 and 19 via a wire. The power supply 26 is electrically connected to the input terminal of the time control switch 20 via a wire. The positive terminal of the power supply 26 is electrically connected to each solenoid valve 18 and 19 via a wire, and the negative terminal of the power supply 26 is electrically connected to contact 24 via a wire. When it is necessary to automatically control the opening and closing of solenoid valves 18 and 19 on each step of the tiered classroom from top to bottom in a time sequence, the opening and closing time of motor 23 is controlled by time switch 20. When motor 23 starts, it drives lead screw 22 to rotate, thereby driving contact 24 to move along the first direction. During the movement of contact 24, it contacts and conducts electricity with multiple contacts 25 in sequence, thereby automatically controlling the solenoid valves 18 and 19 on each step of the tiered classroom from top to bottom to be connected to power supply 26 in a time sequence. Therefore, the control components with the above structure can effectively improve the automation level of the tiered classroom cleaning device.

[0042] It should be noted that motor 23 is preferably a geared motor 23, and the forward and reverse rotation of motor 23 can be achieved by changing the input phase sequence of power supply 26 of motor 23 or by using a specific control circuit, which is well known to those skilled in the art.

[0043] like Figure 4 As shown, contact 25 is made of spring steel and has a sheet-like structure. After being curved, contact 25 is fixed to the bracket 21 at both ends by screws 27. This arrangement ensures good contact between contact 24 and contact 25, thereby ensuring the continuity of current between contact 24 and contact 25 and guaranteeing the stable operation of the control component.

[0044] The technical solution provided by this utility model involves installing a cleaning mechanism in a tiered classroom, including an air pump 6 and multiple air nozzles 1, with the air pump 6 connected to each air nozzle 1 via an air supply pipeline. When cleaning is required, the cleaning staff powers on the air pump 6, which generates a strong airflow. This airflow is delivered to the air nozzles 1 via the air supply pipeline. As the air nozzles 1 release the airflow, trash is blown away from the steps 2, starting from the top of the tiered classroom and proceeding downwards layer by layer until reaching the bottom. Because the trash is gradually guided to the bottom, the cleaning staff only needs to collect the trash once at the lowest point of the tiered classroom. This continuous and orderly workflow significantly improves cleaning efficiency and reduces labor costs. This not only makes cleaning more efficient and convenient but also helps maintain the cleanliness and hygiene of the tiered classroom, providing a more comfortable learning environment for teachers and students.

[0045] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
