Description

Technical Field

[0001] This utility model relates to the field of road sweeping equipment, and in particular to a blower device for a composite sweeper. Background Technology

[0002] In urban road cleaning operations, pedestrian auxiliary lanes, as the main passage areas for pedestrians, directly impact the city's image and residents' travel experience with their environmental sanitation. However, the actual usage scenarios of pedestrian auxiliary lanes are extremely complex, with parked bicycles, carelessly discarded debris, and various stubborn stains frequently appearing. Traditional sweepers rely solely on brushes for cleaning, which, faced with these complex situations, struggles to thoroughly remove all kinds of garbage and stains, failing to meet increasingly stringent environmental sanitation requirements.

[0003] To address this challenge, small new energy sweepers employ a front-mounted water flushing device. This device uses water jets to remove stubborn stains and debris, which are then collected by brushes, improving cleaning efficiency to some extent. However, due to the small size and limited space of these sweepers, their water tanks have relatively small capacities. During extended sweeping operations, they cannot meet the continuous water demand for flushing. Frequent refills not only interrupt cleaning and reduce efficiency but also significantly increase operating costs, limiting the practical application of this solution.

[0004] Some manufacturers have attempted to solve the problem by adding a blower instead of a flushing device. The blower uses airflow to direct debris to easier-to-clean areas, theoretically increasing cleaning efficiency. However, in practice, it has been found that ordinary blowers require significant power to achieve effective cleaning, which greatly increases energy consumption and severely impacts the vehicle's range. While reducing the blower's power can decrease energy consumption, insufficient airflow makes it difficult to effectively remove debris and achieve the desired cleaning results.

[0005] It is evident that current small sweepers face problems such as insufficient water volume for flushing and the contradiction between blower power and battery life in complex pedestrian auxiliary road cleaning operations. There is an urgent need for an innovative solution to resolve the contradiction between blower power and battery life, and to achieve efficient, stable and long-lasting cleaning operations.

[0006] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0007] The main purpose of this utility model is to solve the technical problem that existing sweepers are unable to balance the contradiction between sweeping function and energy consumption during sweeping operations.

[0008] To achieve the above objectives, this utility model provides a composite sweeper blowing device, which is used in sweeper vehicles. The composite sweeper blowing device comprises:

[0009] Main fan, small fan, main fan exhaust outlet, blower duct, blower pipe;

[0010] The main fan is installed inside the sweeper, and the exhaust port of the main fan is connected to the main fan.

[0011] The blower duct is inside the main blower exhaust port;

[0012] The small blower is installed on the sweeper vehicle. One end of the blower duct is connected to the small blower, and the other end points to the blower duct. The air outlet of the blower duct faces the ground on the side of the composite sweeper.

[0013] Preferably, the blower duct is fitted inside the blower tube.

[0014] Preferably, the end of the blower tube furthest from the air outlet is on the same horizontal line as the blower tube.

[0015] Preferably, the blower pipe is installed on the garbage bin of the sweeper.

[0016] Preferably, the blower duct is located inside the garbage bin of the sweeper.

[0017] Preferably, the air outlet of the blower pipe has a tapered tapered design, with the flow cross-sectional area gradually decreasing from the air inlet side to the air outlet side.

[0018] Preferably, the main fan exhaust port includes a first exhaust port and a second exhaust port, the blower duct is inside the first exhaust port, and the exhaust from the second exhaust port points to the ground.

[0019] Preferably, the composite sweeper blowing device further includes a sealing plate, which is installed on the exhaust port of the main fan. The angle of the sealing plate is adjustable, and the airflow distribution between the first exhaust port and the second exhaust port is controlled by adjusting the angle of the sealing plate.

[0020] This invention eliminates the need for a high-power purging fan. Instead, it utilizes a portion of the airflow generated during the operation of the main fan in conjunction with a low-power auxiliary fan to replace the traditional high-power purging fan, thereby significantly reducing energy consumption.

[0039] This utility model provides a composite sweeper blowing device, referring to... Figure 1 and Figure 2 In one embodiment, the composite sweeper blowing device is used in a sweeper vehicle. The composite sweeper blowing device includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4. The main fan is installed inside the sweeper vehicle, and the main fan exhaust port 2 is connected to the main fan. The blower duct 3 is inside the main fan exhaust port 2. The small fan 1 is installed on the sweeper vehicle, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4. The air outlet of the blower pipe 4 faces the ground on the side of the composite sweeper.

[0040] Specifically, the composite sweeper blower device utilizes a portion of the airflow generated during the operation of the main blower, along with a small blower 1 of low power, to form a duct in the blower duct 3 with a portion of the exhaust air from the main blower and the airflow from the small blower 1, which is then discharged together from the blower duct 4 to sweep up the garbage on the ground.

[0041] In this embodiment, the main blower and the small blower 1 work together. The main blower is responsible for large-area cleaning, while the small blower 1 specifically strengthens the blowing force on the sides of the vehicle, effectively cleaning hard-to-reach corners such as curbs and wheel wells where garbage easily accumulates. It adapts to different road conditions (such as wet or dry roads) while reducing the load on the main blower and extending its service life. This design eliminates the need for an additional high-power sweeping blower, effectively replacing traditional high-power sweeping blowers, significantly reducing energy consumption, and resolving the contradiction between cleaning function and energy consumption that existing sweepers struggle to balance during cleaning operations, achieving efficient and energy-saving cleaning.

[0042] Reference Figure 1 and Figure 2 In one embodiment, the blower duct 3 is fitted inside the blower duct 4.

[0043] Specifically, the system includes a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4. The main fan is installed inside the sweeper vehicle, and the main fan exhaust port 2 is connected to the main fan. The blower duct 3 is located inside the main fan exhaust port 2. The small fan 1 is installed on the sweeper vehicle. One end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4. The air outlet of the blower pipe 4 faces the side of the composite sweeper and the ground. The blower duct 3 is fitted inside the blower pipe 4.

[0044] In this embodiment, the blower duct 3 is fitted inside the blower duct 4, forming a double-layer structure, which reduces wind power loss and saves installation space. The inner duct delivers high-pressure air from the small blower 1, while the outer duct utilizes the residual air power of the main blower for acceleration. The structure is compact and easy to disassemble and clean.

[0045] Reference Figure 1 and Figure 2 In one embodiment, the end of the blower duct 4 furthest from the air outlet is on the same horizontal line as the blower duct 3.

[0046] Specifically, the blower device of the composite sweeper includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the side of the composite sweeper; the end of the blower pipe 4 away from the air outlet is on the same horizontal line as the blower duct 3.

[0047] In this embodiment, the duct and duct interface are kept horizontally aligned to allow the airflow to flow straight through without obstruction, reduce wind power loss, and make the blowing angle more stable, thus avoiding the scattering of garbage or repeated cleaning and improving cleaning efficiency.

[0048] Reference Figure 1 and Figure 2 In one embodiment, the blower pipe 4 is disposed on the garbage bin of the sweeper.

[0049] Specifically, the blower device of the composite sweeper includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the side of the composite sweeper; the blower pipe 4 is located on the garbage bin of the sweeper.

[0050] Reference Figure 1 and Figure 2 In one embodiment, the blower duct 3 is disposed inside the garbage bin of the sweeper vehicle.

[0051] Specifically, the blower device of the composite sweeper includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the side of the composite sweeper; the blower duct 3 is located inside the garbage bin of the sweeper.

[0052] In this embodiment, the blower duct 3 is placed inside the garbage bin, which can effectively utilize the internal space of the sweeper, rationally arrange the pipes, reduce the space occupied by external pipes, make the overall structure of the sweeper more compact, and at the same time reduce the impact of the external environment on the blower duct 3.

[0053] like Figure 3 As shown, in one embodiment, the air outlet of the blower 4 is a tapered tapered design, with the flow cross-sectional area gradually decreasing from the air inlet side to the air outlet side.

[0054] Specifically, the blower device of the composite sweeper includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the side of the composite sweeper; the air outlet of the blower pipe 4 has a tapered tapered design, with the cross-sectional area gradually decreasing from the air inlet side to the air outlet side.

[0055] In this embodiment, the conical structure at the air outlet of the blower pipe 4 can converge the blown airflow, making the airflow more concentrated and enhancing the sweeping force. This allows for more powerful sweeping of garbage and debris on the road surface, further improving the cleaning effect. The air outlet is designed as a cone shape with a thin front end and a thick rear end, which can increase the wind speed and form a concentrated blowing force, making it easier to blow away small garbage (such as cigarette butts and leaves) stuck in brick seams and on the roadside, like a "wind knife".

[0056] Reference Figure 1 and Figure 2 In one embodiment, the main fan exhaust port 2 includes a first exhaust port and a second exhaust port, the blower duct 3 is inside the first exhaust port, and the exhaust from the second exhaust port points to the ground.

[0057] Specifically, the blower device of the composite sweeper includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the ground on the side of the composite sweeper; the main fan exhaust port 2 includes a first exhaust port and a second exhaust port, the blower duct 3 is inside the first exhaust port, and the exhaust from the second exhaust port points towards the ground.

[0058] In this embodiment, the exhaust vent of the main blower is divided into two channels: the air from the first exhaust vent blows into the blower duct 3, and together with the air from the small blower 1, it blows into the blower duct 4. In order not to affect the vehicle's vacuuming and sweeping operation, the other part of the exhaust air from the main blower is discharged directly from the second exhaust vent to reduce the exhaust resistance of the main blower and ensure the vacuuming and sweeping operation effect. At the same time, the two air streams do not interfere with each other, making the operation more stable.

[0059] Reference Figure 1 and Figure 2 In one embodiment, the composite sweeper blowing device further includes a sealing plate, which is installed on the main fan exhaust port 2. The angle of the sealing plate is adjustable, and the airflow distribution between the first exhaust port and the second exhaust port is controlled by adjusting the angle of the sealing plate.

[0060] Specifically, the composite sweeper blowing device includes: a main fan, a small fan 1, a main fan exhaust port 2, a blower duct 3, and a blower pipe 4; the main fan is installed inside the sweeper, and the main fan exhaust port 2 is connected to the main fan; the blower duct 3 is inside the main fan exhaust port 2; the small fan 1 is installed on the sweeper, one end of the blower duct 3 is connected to the small fan 1, and the other end points towards the blower pipe 4, with the air outlet of the blower pipe 4 facing the side of the composite sweeper; the composite sweeper blowing device also includes a sealing plate, which is installed on the main fan exhaust port 2, and the angle of the sealing plate is adjustable, thereby controlling the airflow distribution between the first and second exhaust ports by adjusting the angle of the sealing plate.

[0061] In this embodiment, airflow distribution is controlled by adjusting the sealing plate angle. Simultaneously, the main fan exhaust port 2 is divided into two parts. One part is discharged through the first exhaust port, forming a parallel air duct with the blower duct 3, and discharged together through the blower duct 4 to sweep away ground debris, thus widening the working area. To avoid affecting the vehicle's sweeping operation, the other part of the main fan exhaust is discharged directly from the second exhaust port, reducing the main fan's exhaust resistance and ensuring effective sweeping. Adjusting the sealing plate angle also allows for flexible adjustment of the main fan's exhaust airflow direction and volume according to actual needs in different cleaning scenarios, such as cleaning different types of road debris and different road conditions. This achieves more precise and efficient cleaning operations while further optimizing energy consumption and improving energy efficiency. Adjusting the sealing plate angle also allows for flexible allocation of the blowing and suction power ratio. For example, increasing the blowing power when there is a lot of debris helps to gather it in advance; allocating more power to suction when there is less debris saves energy. In the future, sensors can be added to achieve automatic adjustment.

[0062] Reference Figure 4 , Figure 5In one embodiment, when the composite sweeper blowing device of this utility model is applied to a sweeper, after the main fan is started, negative pressure suction is generated through the main fan pipe 6. The sweeping brush device 5 sweeps the ground garbage to the suction cup, and the garbage enters the garbage bin 7 through the main fan pipe 6 with the airflow to complete the initial collection. The airflow of the main fan exhaust port 2 is divided into two paths. One path enters the axial extension of the main fan exhaust port 2 and mixes with the high-pressure auxiliary airflow output by the small fan 1 through the blower pipe 3 to form a composite airflow. The other path is directly discharged to the ground through the lateral extension to balance the back pressure. The mixed airflow passes through the conical tapered structure at the air outlet of the blower pipe 4. After acceleration, a high-speed air blade is formed, which precisely blows away stubborn garbage from the side of the vehicle, the curb, and the cracks between bricks, pushing it into the suction coverage area of ​​the main blower. The sealing plate dynamically distributes the airflow ratio of the main blower exhaust port 2 through angle adjustment. When the garbage is dense, the blowing airflow is increased to enhance the cleaning effect, and when the garbage is less, the blowing power is reduced to save energy. The design of the blower duct 3 embedded in the garbage bin 7 reduces the space occupied by external pipes. Combined with the double-layer nested blower duct 4 structure, the airflow transmission efficiency is optimized, ultimately achieving a balance between high-efficiency cleaning and low energy consumption, and solving the contradiction between blower power and battery life in traditional sweepers.

[0063] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
