[0025] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] See Figure 1 and Figure 2 The cleaning device 10 in one embodiment includes a shell 100, a pneumatic component 200 and a working device 300. A accommodating chamber 110 is formed in the shell 100; the working device 300 is arranged in the accommodating chamber 110, and the working device 300 and at least one side inner wall of the accommodating chamber 110 are spaced apart to form an exhaust duct 120; a first exhaust port 211 is provided on the pneumatic component 200, and a second exhaust port 130 connected to the exhaust duct 120 is provided on the shell 100, and the first exhaust port 211 is connected to the second exhaust port 130 through the exhaust duct 120.

[0027] By placing the working device 300 within the accommodating chamber 110, an exhaust duct 120 is formed within the accommodating chamber 110. The first exhaust port 211 and the second exhaust port 130 are connected via the exhaust duct 120. The airflow generated by the first exhaust port 211 of the pneumatic assembly 200 flows through the exhaust duct and out of the second exhaust port 130. This airflow causes a certain amount of airflow loss in the exhaust duct 120, reducing the airflow volume and, in turn, the noise of the airflow, thereby improving the user comfort of the cleaning device 10.

[0028] See Figure 1 and Figure 3 In one embodiment, the pneumatic assembly 200 includes a fan 220 and a flow guide 210. The fan 220 is disposed within the accommodating chamber 110. The flow guide 210 is disposed at the first air outlet 211. The flow guide 210 has an air guide opening that faces the exhaust duct 120. The first air outlet 211 communicates with the exhaust duct 120 through the air guide opening. The airflow generated by the fan 220 is redirected by the air guide opening so that the airflow flows into the exhaust duct 120.

[0029] See Figure 1 and Figure 3 In one embodiment, the guide 210 is an elastic member that can provide elastic buffering when the fan 220 is subjected to force. In addition to changing the wind direction, the guide 210 can also protect the fan 220, further ensuring the reliability and practicality of the cleaning device 10.

[0030] In one embodiment, the cleaning device 10 further includes a drive device 400, which is disposed within the exhaust duct 120. The drive device 400 is disposed within the exhaust duct 120. As air flows through the exhaust duct, it removes heat from the drive device 400, lowering the temperature of the drive device 400 and thereby reducing wear and tear on the drive device 400, thereby ensuring the lifespan of the drive device 400. This further improves the practicality and user comfort of the cleaning device 10.

[0031] In one embodiment, the working device 300 is located in the center of the accommodating chamber 110. The exhaust duct 120 surrounds the working device 300. The first exhaust port 211 and the second exhaust port 130 are spaced apart, dividing the exhaust duct 120 into a first channel 121 and a second channel 122. The path length of the first channel 121 is greater than the path length of the second channel 122. The driving device 400 is disposed within the first channel 121. As a result, the airflow generated by the pneumatic device can pass through the first and second channels 121, 122, and be discharged from the second exhaust port 130. Furthermore, because the path length of the first channel 121 is greater than the path length of the second channel 122, the airflow suffers greater losses during its passage through the first channel 121 and exit from the second exhaust port 130, thereby reducing the noise of the airflow. The presence of the driving device 400 within the first channel 121 also ensures that the airflow has sufficient space to dissipate the heat generated by the driving device 400. Therefore, not only the noise of the airflow is reduced, but the airflow can also take away the heat of the driving device 400, thereby improving the efficiency of the exhaust duct 120 and ensuring the practicality of the structural design of the cleaning device 10.

[0032] In one embodiment, the two opposing side surfaces of the working device 300 abut against the two opposing side surfaces within the accommodating chamber 110, allowing the exhaust duct 120 to surround the working device 300. In other words, the top and bottom surfaces of the working device 300 abut against the top and bottom walls of the accommodating chamber 110, respectively. This allows the exhaust duct 120 to surround the working device 300, further effectively consuming the airflow generated by the pneumatic assembly 200 and ensuring the practicality of the cleaning device 10.

[0033] In one embodiment, the cleaning device 10 further includes a water tank assembly 500. The working device 300 includes a dust box assembly 310. The dust box assembly 310 is positioned in the center of the accommodating chamber 110. The water tank assembly 500 is positioned adjacent to the dust box assembly 310 and within the second channel 122. The water tank assembly 500 is positioned within the second channel 122 and spaced from one inner wall of the second channel 122. Thus, the first channel 121 and the second channel 122 can be positioned around the dust box assembly 310. The airflow generated by the pneumatic assembly 200 is discharged through the first channel 121 and out of the second exhaust port 130, removing heat generated by the drive device 400. The drive device 400 also consumes and reduces the flow rate and velocity of the airflow. A small portion of the airflow generated by the pneumatic assembly 200 can be discharged through the second channel 122, through the water tank assembly 500, and out of the second exhaust port 130. The water tank assembly 500 also consumes the airflow within the second channel 122, thereby reducing noise generated by the airflow. This ensures that the airflow generated by the pneumatic component 200 has sufficient channels to be discharged outward, and at the same time, the airflow can be consumed by different components to reduce the noise generated by the airflow, further ensuring the reliability and practicality of the cleaning device 10 and improving the user comfort of the cleaning device 10.

[0034] In one embodiment, the drive device 400 includes at least two drive assemblies, each of which is spaced apart along the length of the exhaust duct 120. This ensures that the airflow within the exhaust duct 120 has sufficient contact area with each drive assembly, ensuring that the airflow effectively dissipates heat from the at least two drive assemblies within the exhaust duct 120. The spacing between the at least two drive assemblies further reduces the amount of airflow obstructed by the at least two drive assemblies, thereby further damaging the airflow, reducing the flow rate and velocity, and thus reducing airflow noise.

[0035] See Figure 1 In one embodiment, the driving device 400 includes a first driving component 410, which is used to drive the moving wheel. The first driving component 410 is arranged in the first channel 121 and has a gap with at least part of the inner wall of the exhaust duct 120 in the radial direction of the exhaust duct 120. As a result, the first driving component 410 can drive the moving wheel. During the movement of the cleaning device 10, the operation of the first driving component 410 will generate a large amount of heat. The first driving component 410 is located in the first channel 121, and the heat of the first driving component 410 can be discharged outward from the second exhaust port 130 through the first channel 121 by the airflow. At the same time, the structure of the first driving component 410 can also cause loss of airflow, thereby reducing the flow rate and flow of the airflow, and reducing the noise of the airflow at the second exhaust port 130. The practicality and comfort of use of the cleaning device 10 are further improved.

[0036] See Figure 1 In one embodiment, the drive device 400 includes a second drive assembly 420 for driving a side brush or a roller brush. The second drive assembly 420 is disposed within the first channel 121 and has a clearance from at least a portion of the inner wall of the exhaust duct 120 in the radial direction of the exhaust duct 120. This allows the second drive assembly 420 to drive the side brush or roller brush to rotate for cleaning. During movement of the cleaning device 10, the second drive assembly 420 generates a significant amount of heat due to driving the side brush or roller brush. Since the second drive assembly 420 is located within the first channel 121, airflow can dissipate the heat generated by the second drive assembly 420 through the first channel 121 and out the second exhaust port 130. Furthermore, the structure of the second drive assembly 420 can also reduce airflow losses, thereby reducing the velocity and volume of the airflow and reducing noise at the second exhaust port 130. This further enhances the practicality and user comfort of the cleaning device 10.

[0037] See Figure 1 In one embodiment, the drive device 400 includes a third drive assembly 430, which is used to drive the sweeping and mopping element. The third drive assembly 430 is positioned within the first channel 121 or the second channel 122, with a clearance from at least a portion of the inner wall of the exhaust duct 120 in the radial direction of the exhaust duct 120. This allows the third drive assembly 430 to rotate and clean the sweeping and mopping element. During the movement of the cleaning device 10, the third drive assembly 430 generates a significant amount of heat. Since the third drive assembly 430 is located within the first channel 121, the heat generated by the third drive assembly 430 can be dissipated through the first channel 121 and out of the second exhaust port 130. The structure of the third drive assembly 430 also reduces airflow losses, thereby reducing the velocity and volume of the airflow and reducing noise at the second exhaust port 130. This further enhances the practicality and user comfort of the cleaning device 10. Specifically, the sweeping and mopping element can be a roller brush, a side brush, other cleaning elements, or a dust collector.

[0038] See Figure 1In one embodiment, the first and second drive members are positioned near the inner wall of the accommodating chamber 110 on a side away from the first air outlet 211, and the third drive member is positioned near the second air outlet 130. The first, second, and third drive members are sequentially spaced apart within the first channel 121. The second drive member is positioned between the first and third drive members within the first channel 121. Airflow passes through the first, second, and third drive members in sequence within the first channel 121, removing heat generated by the first, second, and third drive members. At the same time, the first, second, and third drive members reduce the flow rate and velocity of the airflow, thereby reducing the noise emitted by the airflow at the second air outlet 130. This further ensures the practicality and user comfort of the cleaning device 10. It should be noted that the first, second, and third drive members are all gear sets or gearbox structures. Gear sets or gearbox structures can generate heat during operation, leading to excessive temperatures, which can affect the normal operation of the gear sets or gearbox structures and cause abnormal noise or other problems. When the air flows through the exhaust duct, it can remove heat from the gear set or gear box structure, reducing the temperature of the gear set or gear box structure and thus reducing wear of the gear set or gear box structure, thereby avoiding problems such as abnormal noise from the gear set or gear box, further ensuring the reliability and practicality of the cleaning device 10.

[0039] In another embodiment, a side wall of the working device 300 is disposed adjacent to a side wall of the accommodating chamber 110, an exhaust duct 120 is disposed around the working device 300, and a first exhaust port 211 and a second exhaust port 130 are disposed on either side of the side wall where the working device 300 connects to the side wall of the accommodating chamber 110. The first exhaust port 211 is connected to the second exhaust port 130 via the exhaust duct 120. The side wall of the working device 300 is disposed adjacent to the side wall of the accommodating chamber 110, so that the airflow generated by the first exhaust port 211 cannot flow along this side wall of the working device 300. Instead, the airflow flows around the working device 300 and is discharged through the second exhaust port 130.

[0040] In one embodiment, the working device 300 includes a water tank assembly 500 and a dust box assembly 310. The water tank assembly 500 is disposed adjacent to a side wall of the accommodating chamber 110, and the dust box assembly 310 is disposed adjacent to the side of the water tank assembly 500 facing away from the accommodating chamber 110. The first exhaust port 211 and the second exhaust port 130 are located on opposite sides of the water tank assembly 500, respectively, and the exhaust duct 120 is disposed around the dust box assembly 310. In this embodiment, airflow cannot flow through the water tank assembly 500 to the second exhaust port 130, but instead flows around the outer surface of the dust box assembly 310. This ensures that the airflow must flow along a longer flow path. This ensures that the components and equipment within the accommodating chamber 110 can consume the airflow, thereby reducing the velocity and flow rate of the airflow, thereby reducing the noise of the airflow.
