[0060] The dust box of the cleaning robot has a small space, which makes it difficult to store a large amount of dust and garbage, and the user needs to dump the garbage frequently. In order to reduce the frequency of users dumping dust and garbage, the cleaning robot is usually used with a dust collection base station. After the dust box of the cleaning robot collects a certain amount of dust and garbage, the base station can absorb the dust and garbage in the dust box into the dust collection structure of the base station, so that the cleaning robot can continue to work. However, the base station in the related art will generate a lot of noise when collecting dust and garbage in the dust box of the cleaning robot, which affects the user experience.

[0061] To this end, the utility model provides a dust collection system, a base station and a cleaning system.

[0062] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0063] Referring to FIG. 1 (A) and FIG. 1 (B), the utility model provides a dust collection system 1001, which can collect dirt from a target object. Exemplarily, the target object includes at least one of the following: inside an object, on the surface of an object, on the ground, on a wall, etc. Exemplarily, the dirt includes at least one of the following: garbage, dust, liquid, etc.

[0064] Please refer to FIG. 1(A) and FIG. 1(B). In some embodiments, the target object is a cleaning robot 2000, and the dust collection system 1001 can collect dirt at the cleaning robot 2000 to ensure that the cleaning robot 2000 can perform normal cleaning work. Please refer to FIG. 1(A). For example, the cleaning robot 2000 includes a dust box 2001. The dust collection system 1001 can collect or clean the dirt in the dust box 2001, so that the dust box 2001 of the cleaning robot 2000 can normally contain the dirt, thereby providing a guarantee for the cleaning robot 2000 to perform normal cleaning work later.

[0065] Please refer to FIG. 1(A) and FIG. 1(B). In some embodiments, the dust collection system 1001 includes a power assembly 100, a dust collection assembly 200, an air guide structure 300 and a noise reduction structure 400. The power assembly 100 is used to drive the dirt to be transferred to the dust collection assembly 200, and the dust collection assembly 200 is used to contain the dirt. Exemplarily, the power assembly 100 can generate a negative pressure in the dust collection channel of the dust collection system 1001, so that the dirt in the dust box 2001 of the cleaning robot 2000 or the dirt in other areas can be sucked to the dust collection assembly 200; when the airflow including the dirt is transported to the dust collection assembly 200, the dirt can be collected at the dust collection assembly 200, and the airflow can be output from the dust collection assembly 200. Exemplarily, the power assembly 100 includes at least one of the following: a fan, a pump. Exemplarily, the air guide structure 300 is used to connect the power assembly 100, and the airflow discharged from the power assembly 100 can be discharged through the air guide structure 300. Exemplarily, the air guide structure 300 is used to connect the dust collecting assembly 200 , and the airflow and / or dirt can enter the dust collecting assembly 200 through the air guide structure 300 , and the airflow discharged from the dust collecting assembly 200 can be transported to the power assembly 100 .

[0066] Please refer to FIG. 2 (A). In some embodiments, the dust collection system 1001 includes a dust collection duct 301 and a guide duct 302. The dust collection duct 301 is connected to the dust collection assembly 200, and the guide duct 302 is connected to the power assembly 100. Under the suction action of the power assembly 100, the airflow and / or dirt can enter the dust collection assembly 200 through the dust collection duct 301, and the airflow discharged from the dust collection assembly 200 can be discharged through the power assembly 100 and the guide duct 302 in sequence. Exemplarily, the dust collection duct 301 can include the air guide structure 300 of any embodiment of the utility model. Exemplarily, the guide duct 302 can include the air guide structure 300 of any embodiment of the utility model. Exemplarily, the dust collection duct 301 and the guide duct 302 respectively include the air guide structure 300 of any embodiment of the utility model, and the specific structure of the dust collection duct 301 can be the same as or different from that of the guide duct 302.

[0067] Please refer to FIG. 1(A) and FIG. 1(B). Exemplarily, the dust collecting assembly 200 includes a dust collecting part 201, which is used to contain dirt; the power assembly 200 is formed with an inner air duct 30, which is connected to the dust collecting assembly 200, and the air guide structure 300 is connected to the dust collecting assembly 200 or the power assembly 100. At least two of the dust collecting assembly 200, the power assembly 100 and the air guide structure 300 are provided with a noise reduction structure 400, and the dust collecting part 201, the inner air duct 30 and the air guide structure 300 are connected to form an air flow channel, and the noise reduction structure 400 wraps at least a part of the air flow channel along the circumference of the air flow channel. For example, the noise reduction structure 400 is provided at two of the dust collecting component 200, the power component 100 and the air guiding structure 300, wherein a part of the noise reduction structure 400 is provided outside one of the dust collecting component 200, the power component 100 and the air guiding structure 300, and another part of the noise reduction structure 400 is provided outside the other one of the dust collecting component 200, the power component 100 and the air guiding structure 300. For another example, the noise reduction structure 400 is provided at the dust collecting component 200, the power component 100 and the air guiding structure 300, and the noise reduction structure 400 is divided into three parts, which are respectively provided at the dust collecting component 200, the power component 100 and the air guiding structure 300. Exemplarily, the noise reduction structure 400 is provided at the dust collecting component 201, the power component 100 and the air guiding structure 300.

[0068] It can be understood that the purpose of setting up the noise reduction structure 400 is to absorb or silence sound. If the noise reduction structure 400 is set in the dust collecting piece 201, the inner air duct 30 and the air guiding structure 300, the noise reduction structure 400 will occupy a certain area of ​​the air flow channel in the dust collecting piece 201, the inner air duct 30 and the air guiding structure 300, so that when the airflow flows through the dust collecting piece 201, the inner air duct 30 and the air guiding structure 300, the flow resistance increases, the noise increases, and then the working power of the power component 100 used to provide driving force for dirt increases, thereby increasing the noise to a certain extent, making the final noise reduction effect not obvious.

[0069] When the dust collection system 1001 of this embodiment is working, the noise reduction structure 400 can, to a certain extent, prevent the noise generated by at least two of the dust collection component 200, the power component 100 and the air guide structure 300 from propagating outward, thereby reducing the noise. In addition, since the noise reduction structure 400 wraps at least part of the air flow channel formed by the dust collection component 201, the inner air duct 30 and the air guide structure 300, that is, the noise reduction structure 400 is arranged outside the air flow channel formed by the dust collection component 201, the inner air duct 30 and the air guide structure 300. Therefore, the noise reduction structure 400 occupies less area of ​​the air flow channel formed by the dust collection component 201, the inner air duct 30 and the air guide structure 300, and can achieve low flow resistance noise reduction, effectively reduce the working power required by the power component 100, and the reduction of the working power of the power component 100 also correspondingly reduces the noise at the source, effectively improving the overall noise reduction effect, improving the user experience, and saving energy and environmental protection.

[0070] It should be noted that, referring to Figure 1(B), the airflow channel formed by the dust collecting piece 201, the inner air duct 30 and the air guide structure 300 in the present application refers to the main circulation channel for the airflow flowing in the dust collecting piece 201, the inner air duct 30 and the air guide structure 300. For example, as shown in Figure 1(B), it points from the air inlet of the dust collecting piece 201 to the air outlet of the air guide structure 200.

[0071] In some embodiments, Figure 3 As shown, the power assembly 100 includes a fan module 20, which can generate negative pressure in the dust collection channel of the dust collection system 1001, so that the dirt in the dust box 2001 of the cleaning robot 2000 or the dirt in other areas can be sucked into the dust collecting part 201.

[0072] Please refer to Figure 2(B) and Figure 3 In some embodiments, the power component 100 includes a shell structure 10 and a fan module 20. The fan module 20 is disposed in the shell structure 10. The shell structure 10 and the fan module 20 cooperate to form an inner air duct 30. The inner air duct 30 is used to communicate with the dust collecting component 200. The noise reduction structure 400 includes a first noise reduction structure 401. The first noise reduction structure 401 is disposed outside at least part of the inner air duct 30.

[0073] In the power assembly 100 of the above embodiment, the first noise reduction structure 401 can, to a certain extent, prevent the noise generated by the fan module 20 from propagating outward when it is working, thereby reducing the noise. In addition, since the first noise reduction structure 401 is arranged outside at least part of the inner air duct 30, the first noise reduction structure 401 will not block the inner air duct 30, and can achieve low flow resistance noise reduction, effectively reducing the working power required by the fan module 20. The reduction in the working power of the fan module 20 also correspondingly reduces the noise at the source, effectively improving the overall noise reduction effect, improving the user experience, and saving energy and protecting the environment.

[0074] Exemplarily, the inner air duct 30 is in communication with the dust collecting assembly 200. When the power assembly 100 is working, dirt can follow the airflow to move to the dust collecting assembly 200, and the dust collecting assembly 200 can collect the dirt in the airflow, thereby cleaning the dirt.

[0075] See also Figure 3 and Figure 4 In some embodiments, the housing structure 10 includes a first housing 11, a second housing 12 and a first vibration reduction mechanism 13. The fan module 20 is arranged in the first housing 11; the second housing 12 is sleeved outside the first housing 11, and the first housing 11 and the second housing 12 are arranged at intervals along the radial direction of the power assembly 100; the first vibration reduction mechanism 13 is arranged between the first housing 11 and the second housing 12 along the radial direction of the power assembly 100. Both the first housing 11 and the second housing 12 can play a role in sound insulation and noise reduction to a certain extent, thereby reducing the noise output to the outside when the fan module 20 is working. In addition, the setting of the first vibration reduction mechanism 13 can, to a certain extent, hinder the vibration generated by the fan module 20 when working from the first housing 11 to the second housing 12, thereby effectively reducing the noise output to the outside when the fan module 20 is working.

[0076] For example, the radial direction of the power assembly 100 is perpendicular to Figure 3 The X direction in .

[0077] Exemplarily, the radial direction of the power assembly 100 is perpendicular to the axial direction of the power assembly 100 .

[0078] For example, the radial direction of the power assembly 100 refers to the direction of the airflow in the inner air duct 30 ( Figure 3 The direction is perpendicular to the direction indicated by the thick dashed arrow.

[0079] It is understandable that the cross-sectional profile of the power assembly 100 may be circular, substantially circular, elliptical, other regular shapes or irregular shapes, etc. Exemplarily, the cross-sectional profile of the fan module 20 is perpendicular to the flow direction of the airflow.

[0080] See also Figure 5 and Figure 6In some embodiments, the first shell 11 includes a first shell portion 111 and a second shell portion 112, the first shell portion 111 is connected to the second shell portion 112, the first shell portion 111 and the second shell portion 112 are arranged along the airflow direction, and the first shell portion 111 is located upstream of the second shell portion 112 in the airflow direction. Exemplarily, the connection method between the first shell portion 111 and the second shell portion 112 may include at least one of the following: adhesive connection, snap connection, screw locking connection, magnetic connection, etc. In this way, the assembly of the fan module 20 is facilitated, and the assembly of the power component 100 is convenient and fast. Exemplarily, the hollow first shell portion 111 and the hollow second shell portion 112 cooperate to form a receiving space 113 (please refer to Figure 6 ), the fan module 20 is accommodated in the accommodation space 113.

[0081] See also Figure 5 and Figure 6 In some embodiments, the second shell 12 includes a third shell 121 and a fourth shell 122, the third shell 121 is connected to the fourth shell 122, the third shell 121 and the fourth shell 122 are arranged along the airflow direction, and the third shell 121 is located upstream of the fourth shell 122 in the airflow direction. Exemplarily, the connection method between the third shell 121 and the fourth shell 122 may include at least one of the following: adhesive connection, snap connection, screw locking connection, magnetic connection, etc. In this way, it is convenient to assemble the components in the second shell 12 (such as the first shell 11 or the fan module 20, etc.), and the assembly of the power assembly 100 is convenient and fast. Exemplarily, the third shell 121 is sleeved outside the first shell 111, and the fourth shell 122 is sleeved outside the first shell 111 and the second shell 112.

[0082] See also Figure 5 and Figure 6 In some embodiments, the first vibration damping mechanism 13 includes a first vibration damping member 131 and a second vibration damping member 132. The first vibration damping member 131 is disposed between the first housing 11 and the second housing 12 along the radial direction of the power assembly 100; the second vibration damping member 132 is disposed between the first housing 11 and the second housing 12 along the radial direction of the power assembly 100, and the second vibration damping member 132 and the first vibration damping member 131 are disposed at intervals along the axial direction of the power assembly 100. In this way, the first vibration damping mechanism 13 can play the role of vibration reduction and noise reduction (i.e., noise reduction), and the structure of the first vibration damping mechanism 13 is simple. Compared with only one vibration damping member disposed along the axial direction of the power assembly 100, the technical solution provided in this embodiment is to distribute the first vibration damping member 131 and the second vibration damping member 132 at intervals along the axial direction of the power assembly 100, so that the vibration reduction and noise reduction effect of the power assembly 100 is better.

[0083] In some embodiments, the spacing between the first shell 11 and the second shell 12 is in the range of [2mm, 20mm], for example, the spacing between the first shell 11 and the second shell 12 is 2mm, 5mm, 10mm, 15mm, 20mm or any other suitable value between 2mm-20mm. After testing, the inventors found that when the spacing between the first shell 11 and the second shell 12 is in the above range, it can ensure a good sound insulation effect while the volume of the entire power assembly 100 is not too large, which can ensure cost-effectiveness. In order to ensure a good sound insulation effect, the surface density of the first shell 11 and the second shell 12 is required to be greater than or equal to 10 kilograms per square meter.

[0084] Exemplarily, the axial direction of the power assembly 100 is perpendicular to the radial direction of the power assembly 100 .

[0085] For example, the axial direction of the power assembly 100 is Figure 3 Parallel to the X direction.

[0086] Exemplarily, the axial direction of the power assembly 100 is parallel to the flow direction of the airflow in the inner air duct 30 .

[0087] See also Figure 6 , combined with Figure 3 Exemplarily, the first vibration damper 131 is sleeved outside the first shell 11, the second shell 12 is sleeved outside the first vibration damper 131 and the first shell 11, and the first vibration damper 131 is located between the first shell 11 and the second shell 12 along the radial direction of the power assembly 100.

[0088] See also Figure 6 , combined with Figure 3 Exemplarily, the second vibration damper 132 is sleeved outside the first shell 11, the second shell 12 is sleeved outside the second vibration damper 132 and the first shell, and the second vibration damper 132 is located between the first shell 11 and the second shell 12 along the radial direction of the power assembly 100.

[0089] See also Figure 6 , combined with Figure 3In some embodiments, the first noise reduction structure 401 includes a sound insulation cavity 4011 disposed outside the inner air duct 30, the first vibration damper 131 is sealedly connected to the first shell 11 and the second shell 12, and the second vibration damper 132 is sealedly connected to the first shell 11 and the second shell 12, so that the first shell 11, the second shell 12 and the first vibration damping mechanism 13 cooperate to form a sealed sound insulation cavity 4011. It can be understood that the first vibration damper 131 is sealedly connected to the first shell 11 and the second shell 12 includes: the first vibration damper 131 is sealedly connected to the first shell 11, and the first vibration damper 131 is sealedly connected to the second shell 12. Exemplarily, the first vibration damper 131 is sealedly connected to the first shell 11, that is, the connection between the first vibration damper 131 and the first shell 11 is sealed, and the medium in the soundproof cavity 4011 (the medium includes at least one of gas, solid and liquid) is not easy or will not leak to the outside of the soundproof cavity 4011 through the connection between the two, or the medium outside the soundproof cavity 4011 is not easy or will not enter the soundproof cavity 4011 through the connection between the two. The first vibration damper 131 is sealedly connected to the second shell 12, that is, the connection between the first vibration damper 131 and the second shell 12 is sealed, and the medium in the soundproof cavity 4011 (the medium includes at least one of gas, solid and liquid) is not easy or will not leak to the outside of the soundproof cavity 4011 through the connection between the two, or the medium outside the soundproof cavity 4011 is not easy or will not enter the soundproof cavity 4011 through the connection between the two. The sealed connection at other positions of the present invention is similar, and will not be repeated here.

[0090] See also Figure 6 , and combined with Figure 3 In some embodiments, the wall of the soundproof cavity 4011 wraps at least part of the fan module 20. The soundproof cavity 4011 wraps the fan module 20, so that when the fan module 20 is working, even if vibration and sound are generated from multiple directions, the soundproof cavity 4011 can prevent the vibration and sound from being transmitted to the outside to a certain extent, and can further improve the noise reduction effect of the power assembly 100 while ensuring that the dust collection system 1001 can normally collect dirt. The wall of the soundproof cavity 4011 can completely wrap the fan module 20; or, the soundproof cavity 4011 partially wraps the fan module 20, for example, the soundproof cavity 4011 only wraps part of the fan module 20 along the circumference of the power assembly 100. Exemplarily, the wrapping area of ​​the wall of the soundproof cavity 4011 wrapping the fan module 20 is S1, and the cross-sectional area of ​​the fan module 20 is S2. The larger the ratio of S1 to S2, the better the noise reduction effect.

[0091] See also Figure 6 , and combined with Figure 3In some embodiments, along the axial direction of the power assembly 100, the first vibration damper 131 is close to the first end M1 of the fan module 20, and the second vibration damper 132 is close to the second end M2 of the fan module 20. In this way, vibration dampers can be provided at corresponding positions at both ends of the fan module 20 (vibration source) as much as possible, and the first vibration damper 131 and the second vibration damper 132 are respectively close to the two ends of the fan module 20, and the distance between the first vibration damper 131 and the second vibration damper 132 can be as far as possible, so that the volume of the sound insulation cavity 4011 formed by the first shell 11, the second shell 12, the first vibration damper 131 and the second vibration damper 132 can be as large as possible, thereby making the area of ​​the fan module 20 wrapped by the sound insulation cavity 4011 larger, and the vibration reduction and sound insulation effect of the entire power assembly 100 better.

[0092] See also Figure 6 In some embodiments, the soundproof cavity 4011 is empty, and the air layer or dielectric layer in the soundproof cavity 4011 can reduce the noise output by the power assembly 100 to a certain extent. For example, in the radial direction of the fan module 20, the noise or vibration generated by the fan module 20 when working is first reduced by the first shell 11, then reduced by the air layer or dielectric layer in the soundproof cavity 4011, and then reduced again by the second shell 12. Through the layers of obstacles, the noise or vibration is gradually attenuated, thereby effectively reducing the noise output by the power assembly 100 and improving the noise reduction effect of the power assembly 100.

[0093] See also Figure 7 In some embodiments, a first sound absorbing body 4012 is provided in the soundproof cavity 4011. The first sound absorbing body 4012 can absorb or reduce the noise outputted by the power assembly 100 when the fan module 20 is working, and further improve the noise reduction effect of the power assembly 100. For example, in the radial direction of the fan module 20, the noise generated by the fan module 20 when working is first attenuated by the first shell 11, then attenuated by the first sound absorbing body 4012, and then attenuated again by the second shell 12. Through the layers of obstacles, the noise is gradually attenuated, thereby effectively reducing the noise outputted by the power assembly 100, and improving the noise reduction effect of the power assembly 100. It should be noted that the thicker the sound absorbing body, the higher the cost and the more volume it occupies. Therefore, in the embodiment of the present application, the thickness of the first sound absorbing body 4012 can be greater than or equal to 8 mm and less than or equal to 30 mm, so as to ensure that the volume is not too large, thereby ensuring the cost performance of the power assembly 100.

[0094] See also Figures 3 to 5In some embodiments, the housing structure 10 includes a first housing 11 and a second vibration reduction mechanism 14, and the fan module 20 is disposed in the first housing 11; the second vibration reduction mechanism 14 is disposed at at least one of the air inlet 21 and the air outlet 22 of the fan module 20, and at least part of the second vibration reduction mechanism 14 is disposed between the first housing 11 and the fan module 20. The second vibration reduction mechanism 14 can reduce the transmission of noise or vibration generated by the fan module 20 to the outside, effectively control the radiation of vibration or noise to the outside, and improve the noise reduction effect of the power assembly 100.

[0095] See also Figures 3 to 5 In some embodiments, the second vibration damping mechanism 14 includes a third vibration damping member 141 and a fourth vibration damping member 142, and the third vibration damping member 141 is disposed at the air inlet 21 of the fan module 20. In the radial direction of the power assembly 100, at least a portion of the third vibration damping member 141 is disposed between the fan module 20 and the first housing 11. The air inlet 31 of the inner air duct 30 is formed at at least one of the third vibration damping member 141 and the housing structure 10, and the air inlet 31 of the inner air duct 30 is communicated with the air inlet 21 of the fan module 20. The fourth vibration damper 142 is disposed at the air outlet 22 of the fan module 20. The fourth vibration damper 142 is disposed between the fan module 20 and the first housing 11 along the radial direction of the power assembly 100. The air outlet 32 ​​of the inner air duct 30 is formed in at least one of the housing structure 10 and the fourth vibration damper 142. The air outlet 32 ​​of the inner air duct 30 is connected to the air outlet 22 of the fan module 20. The third vibration damper 141 can reduce the transmission of the noise or vibration generated by the fan module 20 to the dust collecting assembly 200 connected to the air inlet 31 of the inner air duct 30; the fourth vibration damper 142 can reduce the transmission of the noise or vibration generated by the fan module 20 to other components (for example, other components include at least one of the following: the first housing 11, the air guide structure 300 connected to the air outlet 32 ​​of the inner air duct 30), effectively controlling the vibration or noise from radiating outward, and improving the noise reduction effect of the power assembly 100.

[0096] It can be understood that at least part of the third vibration damper 141 is arranged between the fan module 20 and the first shell 11, including: part of the third vibration damper 141 is arranged between the fan module 20 and the first shell 11; the entire third vibration damper 141 is arranged between the fan module 20 and the first shell 11.

[0097] See also Figure 3 and Figure 5In some embodiments, the third vibration damper 141 is formed with a first hollow channel 1411, the entrance of the first hollow channel 1411 is the air inlet 31 of the inner air duct 30, and the first hollow channel 1411 is connected to the air inlet 21 of the fan module 20; the fourth vibration damper 142 is formed with a second hollow channel 1421, at least part of the fan module 20 is penetrated by the second hollow channel 1421, and the exhaust port 22 of the fan module 20 and the air outlet 32 ​​of the inner air duct 30 are respectively connected to the second hollow channel 1421. In this way, the third vibration damper 141 including the first hollow channel 1411 can not only play the role of vibration reduction, but also serve as a part of the internal air duct 30. The hollow third vibration damper 141 is also helpful to reduce the weight of the power assembly 100; the fourth vibration damper 142 including the second hollow channel 1421 can not only play the role of vibration reduction, but also accommodate part of the fan module 20, so that the structure of the power assembly 100 is compact and helps to reduce the weight of the power assembly 100. The third vibration damper 141 and the fourth vibration damper 142 can respectively play the role of vibration reduction for the power assembly 100, thereby ensuring that the power assembly 100 has good vibration reduction and noise reduction effects.

[0098] It can be understood that the air outlet 32 ​​of the inner air duct 30 is formed in at least one of the shell structure 10 and the fourth vibration damper 142, which may include: the air outlet 32 ​​of the inner air duct 30 is formed in the shell structure 10, and the air outlet 32 ​​of the inner air duct 30 is communicated with the guide duct 302; or, the air outlet 32 ​​of the inner air duct 30 is formed in the fourth vibration damper 142, and the air outlet 32 ​​of the inner air duct 30 is communicated with the guide duct 302 of the wind guide structure 300; or, the air outlet 32 ​​of the inner air duct 30 is formed in the shell structure 10 and the fourth vibration damper 142, and the air outlet 32 ​​of the inner air duct 30 is communicated with the guide duct 302. Exemplarily, the air outlet 32 ​​of the inner air duct 30 is formed in the first shell 11, and the air outlet 32 ​​of the inner air duct 30 is spaced apart from the exhaust port 22 of the fan module 20. In other embodiments, the air outlet 22 of the fan module 20 or the outlet of the second hollow channel 1421 may also be the air outlet 32 ​​of the inner air duct 30 , which is not limited here.

[0099] See also Figure 3 In some embodiments, the air inlet 31 of the inner air duct 30 is formed on the third vibration damper 141, and the air outlet 32 ​​of the inner air duct 30 is formed on the first housing 11, and the air inlet 31 and the air outlet 32 ​​are arranged at intervals along the axial direction of the power assembly 100. In this way, there is no need for an additional pipe member to form an air inlet and connect to the third vibration damper 141, and there is no need to set up another additional pipe member to form an air outlet and connect to the exhaust port 22 of the fan module 20, which reduces the number of components and simplifies the structure of the power assembly 100; the reduction in the number of components can also improve the processing efficiency to a certain extent and make the processing more convenient to a certain extent.

[0100] See also Figure 3 and Figure 8 In some embodiments, the third vibration damping member 141 includes a first vibration damping section 1412 and a second vibration damping section 1413. The first vibration damping section 1412 is connected to the first shell 11. The first shell 11 is sleeved outside at least part of the first vibration damping section 1412. The first vibration damping section 1412 is sealed with the air inlet 21 of the fan module 20. The second vibration damping section 1413 is connected to one end of the first vibration damping section 1412 away from the air outlet 22 of the fan module 20. At least part of the second vibration damping section 1413 is located outside the first shell 11. The second vibration damping section 1413 is used to be sealed with the dust collecting assembly 200. The second vibration damping section 1413 can realize a sealed connection between the power component 100 and the dust collecting component 200; in addition, since the second vibration damping section 1413 is used to connect with the dust collecting component 200, the third vibration damping member 141 can reduce the vibration at the power component 100 transmitted to the dust collecting component 200, thereby protecting the dust collecting component 200 to a certain extent and improving the noise reduction effect.

[0101] See also Fig. 9 and Fig.10 In some embodiments, the second vibration reduction section 1413 of the third vibration reduction member 141 is used to connect with the dust collection assembly 200. Fig.10, exemplarily, the second vibration reduction section 1413 includes a vibration reduction sub-section 1414, which is used to be arranged between the outer wall of the shell structure 10 and the dust collection component 200, and the length range of the vibration reduction sub-section 1414 is [2mm, 10cm]. For example, the length L of the vibration reduction sub-section 1414 is 2mm, 5mm, 8mm, 10mm or any other suitable value between 2mm-8mm. In this way, the vibration reduction sub-section 1414 can ensure the sealing of the connection between the power component 100 and the dust collection component 200, and prevent the dust and garbage in the dust collection component 200 from leaking out through the connection between the dust collection component 200 and the power component 100. And because the sealing connection between the dust collection component 200 and the power component 100 is good, it can ensure the negative pressure extraction effect of the power component 100 on the dust collection component 200, and can also play a good vibration reduction or vibration isolation effect. Exemplarily, the vibration damping sub-segment 1414 is flexible or elastic, for example, the vibration damping sub-segment 1414 includes a soft rubber vibration damping sub-segment, or other elastic vibration damping sub-segments. It can be understood that according to the Bernoulli principle, since the airflow flowing through the vibration damping sub-segment 1414 is a high-speed fluid, the faster the flow rate of the airflow, the smaller the pressure; in the case where the vibration damping sub-segment 1414 is flexible or elastic, if the length of the vibration damping sub-segment 1414 is too long, it is easy to cause the vibration damping sub-segment 1414 to shrink or collapse inward. If the length of the vibration damping sub-segment 1414 is too short, it is difficult for the vibration damping sub-segment 1414 to play a good sealing role and / or vibration damping effect. The length range of the vibration damping sub-segment 1414 is [2mm, 10cm], which can take into account the sealing performance, the vibration damping effect and reduce the risk of collapse of the vibration damping sub-segment 1414.

[0102] See also Fig.10 In some embodiments, the thickness T of the vibration-damping sub-segment 1414 is greater than or equal to 2 mm, so that the vibration-damping sub-segment 1414 has a good sound insulation effect, reduces the noise generated when the airflow flows through the vibration-damping sub-segment 1414, and further improves the noise reduction effect of the power assembly 100. Exemplarily, the thickness T of the vibration-damping sub-segment 1414 is less than or equal to 20 cm, so as to take into account both good sound insulation effect and small volume.

[0103] See also Figure 8 and Fig.10In some embodiments, the housing of the dust collecting assembly 200 has an air outlet F, and a mounting portion 202 is detachably provided at the air outlet F of the dust collecting assembly 200, and the second vibration reduction section 1413 has a flange 1415 extending radially outward from the power assembly 100. Exemplarily, the flange 1415 extends into the dust collecting assembly 200, and the mounting portion 202 of the dust collecting assembly 200 squeezes the flange 1415 of the second vibration reduction section 1413 between the mounting portion 202 and the housing of the dust collecting assembly 200, so as to achieve the connection between the second vibration reduction section 1413 and the dust collecting assembly 200. Since the mounting portion 202 squeezes the second vibration reduction section 1413, that is, the mounting portion 202 and the second vibration reduction section 1413 are in interference fit, the sealing of the connection between the mounting portion 202 and the second vibration reduction section 1413 can be achieved. Exemplarily, the mounting portion 202 and the end of the second vibration reduction section 1413 away from the first vibration reduction section 1412 are in interference fit. In other embodiments, the dust collecting component 200 and the second vibration damping section 1413 may also be connected in other forms, such as by providing a sealing ring at the connection between the dust collecting component 200 and the second vibration damping section 1413 to achieve sealing at the connection between the dust collecting component 200 and the second vibration damping section 1413.

[0104] It is understandable that the first vibration damper 131, the second vibration damper 132, the third vibration damper 141 and / or the fourth vibration damper 142 can be made of suitable materials according to actual needs, such as materials with elasticity or vibration damping functions. Exemplarily, the first vibration damper 131, the second vibration damper 132, the third vibration damper 141 and / or the fourth vibration damper 142 include at least one of the following: a vibration damper made of rubber or soft glue, a vibration damper made of sealant, a vibration damper made of elastic material, etc.; the sealant includes at least one of the following: epoxy resin sealant, phenolic resin sealant, chloroprene sealant, polyurethane sealant, silicone sealant, etc.

[0105] The first vibration damper 131 can be connected to the first shell 11 and / or the second shell 12. The connection method between the first vibration damper 131 and the first shell 11 includes at least one of the following: snap connection, adhesive connection, extrusion fit, etc. The connection method between the first vibration damper 131 and the second shell 12 includes at least one of the following: snap connection, adhesive connection, extrusion fit, etc. The second vibration damper 132 can be connected to the first shell 11 and / or the second shell 12.

Of course, the third vibration damper 141 can also be fixed to the first housing 11 and / or the fan module 20 by any other suitable connection method such as adhesive bonding.

[0107] The fourth vibration damper 142 can be connected to the first housing 11 and / or the fan module 20. Exemplarily, the fourth vibration damper 142 is connected to the first housing 11, and the connection method between the two includes at least one of the following: snap connection, adhesive connection, extrusion fit, etc. Exemplarily, the fourth vibration damper 142 is connected to the fan module 20, and the connection method between the two includes at least one of the following: snap connection, adhesive connection, extrusion fit, etc. Exemplarily, the fourth vibration damper 142 is connected to the first housing 11 and the fan module 20, and the fourth vibration damper 142 can be fixed under the extrusion fit of the first housing 11 and / or the fan module 20. Of course, the fourth vibration damper 142 can also be fixed to the first housing 11 and / or the fan module 20 by any other suitable connection method such as adhesive bonding.

[0108] See also Figure 3 In some embodiments, the shell structure 10 includes a first shell 11, and the fan module 20 is arranged in the first shell 11. The first noise reduction structure 401 includes a second sound absorbing body 4013, and the second sound absorbing body 4013 is arranged between the first shell 11 and the fan module 20 along the radial direction of the power assembly 100. The second sound absorbing body 4013 can further reduce the noise in the first shell 11 from being transmitted to the outside along the radial direction of the power assembly 100, and further improve the noise reduction effect of the power assembly 100. Exemplarily, the second sound absorbing body 4013 is arranged outside the inner air duct 30, and the second sound absorbing body 4013 will not block the inner air duct 30, which can achieve low flow resistance noise reduction, effectively reduce the working power required by the fan module 20, and the reduction of the working power of the fan module 20 also correspondingly reduces the noise at the source, improves the overall noise reduction effect, improves the user experience, and is energy-saving and environmentally friendly.

[0109] See also Figure 3In some embodiments, the second sound absorbing body 4013 wraps at least a portion of the fan module 20 to improve the sound absorption and noise reduction effects of the second sound absorbing body 4013. Exemplarily, the second sound absorbing body 4013 may completely wrap the circumferential side wall of the fan module 20; or, the second sound absorbing body 4013 partially wraps the fan module 20. In the case where the second sound absorbing body 4013 partially wraps the fan module 20, the wrapping area of ​​the second sound absorbing body 4013 wrapping the fan module 20 can be set according to actual needs and is not limited here. The wrapping area of ​​the second sound absorbing body 4013 wrapping the fan module 20 is S3, and the cross-sectional area of ​​the fan module 20 is S2. The larger the ratio of S3 to S2, the better the sound absorption and noise reduction effects.

[0110] See also Figure 3 , Figure 6 and Figure 7 In some embodiments, the housing structure 10 includes a first housing 11, the fan module 20 is disposed in the first housing 11, and the first noise reduction structure 401 includes a soundproof cavity 4011, which is formed in the housing structure 10. The first noise reduction structure 401 also includes a second sound absorbing body 4013, which is disposed between the first housing 11 and the fan module 20 along the radial direction of the power assembly 100, and the cavity wall of the soundproof cavity 4011 is at least partially wrapped outside the second sound absorbing body 4013. The soundproof cavity 4011 and the second sound absorbing body 4013 cooperate to reduce the noise in the first housing 11 (the noise includes at least one of the following: the noise generated by the fan module 20, and the noise generated by the airflow passing through the inner air duct 30), thereby achieving double noise reduction and improving the noise reduction effect of the power assembly 100. Illustratively, in the radial direction of the fan module 20, the noise generated when the fan module 20 is in operation and / or the noise of the airflow passing through the inner air duct 30 is first attenuated by the second sound-absorbing body 4013, then attenuated by the first shell 11, and then attenuated by the medium layer in the soundproof cavity 4011 or the first sound-absorbing body 4012, and then attenuated again by the second shell 12. The noise is gradually attenuated through layers of obstacles, thereby effectively reducing the noise output by the power component 100 to the outside, and further improving the noise reduction effect of the power component 100.

[0111] In some embodiments, the first sound absorbing body 4012 and / or the second sound absorbing body 4013 can be made of any suitable material. For example, the first sound absorbing body 4012 and / or the second sound absorbing body 4013 include at least one of foamed cotton, sound absorbing cotton, pearl cotton, felt, etc. In this way, the sound absorbing body is cheap and has good sound absorption and noise reduction effects. Exemplarily, the sound absorbing cotton is a porous material that can absorb or isolate noise. The sound absorbing cotton can make the sound reflux in the cavity inside it, thereby effectively achieving the sound absorption or sound insulation function.

[0112] See also Fig.11 and Fig.12 In some embodiments, the dust collecting assembly 200 includes a dust collecting box 203, the dust collecting box 203 is formed with a receiving cavity 2031 for receiving the dust collecting member 201, and the dust collecting member 201 is used to collect dirt received by the cleaning robot 2000; the noise reduction structure 400 includes a second noise reduction structure 402, the second noise reduction structure 402 is arranged in the receiving cavity 2031, the second noise reduction structure 402 is connected to the inner wall of the receiving cavity 2031, and the second noise reduction structure 402 is arranged between the inner wall of the receiving cavity 2031 and the dust collecting member 201. Exemplarily, the dust collecting member 201 can be a breathable or airtight disposable dust collecting member, for example, a disposable breathable dust collecting bag, a disposable airtight dust collecting bag, a disposable dust collecting box, etc.

[0113] It is understandable that if the second noise reduction structure 402 is disposed at the air outlet, air inlet or dirt entrance of the dust collector 201, the second noise reduction structure 402 will occupy a certain flow channel, thereby increasing the flow resistance of the flow channel. The second noise reduction structure 402 is provided for sound absorption or silencing, but since the second noise reduction structure 402 occupies the flow channel area, the flow resistance increases, the noise increases, and the working power of the power component 100 used to provide driving force for the dirt increases, thereby increasing the noise to a certain extent, making the final noise reduction effect not obvious.

[0114] In the dust collecting assembly 200 of this embodiment, since the dust collecting box 203 is provided with a second noise reduction structure 402, the second noise reduction structure 402 is used to be arranged between the inner wall of the receiving cavity 2031 and the dust collecting part 201, the second noise reduction structure 402 can absorb the noise generated when the airflow enters the dust collecting box 203 to a certain extent, thereby reducing the noise output by the base station 1000 when collecting dirt at the cleaning robot 2000, thereby improving the user experience. In addition, the second noise reduction structure 402 is arranged in the dust collecting box 203, and the second noise reduction structure 402 is arranged between the inner wall of the receiving cavity 2031 and the dust collecting part 201, which can reduce or avoid the area of ​​the airflow flow channel occupied by the second noise reduction structure 402 as much as possible, thereby reducing the flow resistance and thus reducing the noise; under the condition of achieving the same dust collecting capacity, the working power of the power assembly 100 can be reduced, thereby reducing the source noise to a certain extent, so that the second noise reduction structure 402 has a good noise reduction effect.

[0115] See also Fig.12 In some embodiments, the dust collecting member 201 is disposed in the receiving cavity 2031 .

[0116] In some embodiments, the dust collecting duct 301 is connected to the dust collecting box 203, and the dust collecting duct 301 is connected to the dust collecting part 201 or the dust collecting box 203. Airflow and / or dirt can enter the dust collecting part 201 through the dust collecting duct 301, thereby cleaning the dirt in the dust box 2001 or other areas to be cleaned. In other embodiments, the dust collecting duct 301 can also be omitted, and the dust collecting duct 301 is replaced by an external duct. The base station 1000 also has a dust collecting port, one end of the dust collecting duct 301 is connected to the dust collecting port, and the other end is connected to the above-mentioned dust collecting part 201 or the dust collecting box 203. Among them, the dust collecting port is used to communicate with the dust box 2001 of the robot.

[0127] See also Fig.12In some embodiments, the second noise reduction structure 402 includes a third sound absorbing body 4021, which is connected to the inner wall of the receiving cavity 2031, and the third sound absorbing body 4021 is formed with a microporous structure. Since the third sound absorbing body 4021 is formed with a microporous structure, the microporous structure can absorb sound, and thus the third sound absorbing body 4021 can cause the sound to reflux in the holes or cavities inside the third sound absorbing body 4021, thereby effectively improving the sound absorption effect.

[0128] In some embodiments, the third sound absorbing body 4021 includes at least one of foamed cotton, sound absorbing cotton, pearl cotton, felt, etc., so that the third sound absorbing body 4021 is cheap and has good sound absorbing effect. Exemplarily, the sound absorbing cotton is a porous material that can absorb or isolate noise, and the sound absorbing cotton can make the sound reflux in the cavity inside it, thereby effectively achieving the sound absorption or sound insulation function.

[0129] In some embodiments, the dust collecting piece 201 includes a breathable dust bag, and the airflow inside the dust collecting piece 201 can be discharged to the power component 100 through the breathable dust bag, so that the power component 100 can form a negative pressure to drive the dirt to be transferred to the dust collecting piece 201 in the dust box 203.

[0130] See also Fig.12 and Fig.13In some embodiments, the dust box 203 is formed with a first connecting port 2032 connected to the air inlet 31 of the power assembly 100; the second noise reduction structure 402 includes a third sound absorbing body 4021 and at least one protrusion 4022, and the third sound absorbing body 4021 is connected to the inner wall of the receiving cavity 2031; the protrusion 4022 is protruded on the side of the third sound absorbing body 4021 away from the inner wall of the receiving cavity 2031, and the protrusion 4022 is arranged between the dust collecting piece 201 and the third sound absorbing body 4021, and at least one protrusion 4022 contacts the dust collecting piece 201, so that the third sound absorbing body 4021 can cooperate with the dust collecting piece 201 to form an airflow space 501, and the airflow space 501 is connected to the first connecting port 2032. It can be understood that the protrusion 4022 is provided between the dust collecting member 201 and the third sound absorbing body 4021, at least one protrusion 4022 contacts the dust collecting member 201, and the protrusion 4022 can support at least part of the third sound absorbing body 4021, so that the protrusion 4022 can cooperate with the third sound absorbing body 4021 to form the airflow space 501. In this way, when the base station 1000 collects dirt at the cleaning robot 2000, it can prevent at least part of the dust collecting member 201 from being close to the third sound absorbing body 4021, so that at least part of the airflow in the dust collecting member 201 can be transported to the airflow space 501, and the airflow in the airflow space 501 can be output to the power assembly 100 through the third connecting port 40211, which is conducive to reducing the flow resistance of the airflow when it flows through the dust collecting member 201. Under the premise of achieving the same dust collection capacity (or the ability to collect dirt), the noise when the airflow passes through the dust collecting member 201 can be reduced, and the power consumption of the power assembly 100 can be reduced. The reduction in power consumption can not only achieve the effect of energy saving, but also reduce the overall noise of the base station 1000 to a certain extent, thereby significantly improving the noise reduction effect. In addition, the protrusion 4022 can also improve the structural strength of the third sound absorbing body 4021.

[0131] See also Fig.13 In some embodiments, at least one protrusion 4022 is provided on at least one of the first wall 40215, the second wall 40216, the third wall 40217, the fourth wall 40218, and the fifth wall 40219.

[0132] See also Fig.13 In some embodiments, the protrusion 4022 and the third sound absorbing body 4021 are integrally formed. In this way, the number of components of the dust box 203 is small, the assembly process is reduced, the assembly efficiency of the dust box 203 is improved, and the dust box 203 is easy to assemble.

[0133] In some embodiments, the protrusion 4022 and the third sound absorbing body 4021 are separate structures, so that the protrusion 4022 can be flexibly arranged. Exemplarily, the connection between the protrusion 4022 and the third sound absorbing body 4021 includes at least one of the following: adhesive connection, snap connection, magnetic connection, screw locking connection, etc.

[0134] The structure and / or shape of the protrusion 4022 can be designed according to actual needs, for example, see Fig.13 , the protrusion 4022 includes a rib 40221. For another example, please refer to Fig.14 , the protrusion 4022 includes a boss 40222.

[0135] The number of the protrusions 4022 can be designed according to actual needs, such as one, two, three or more. When the number of the protrusions 4022 includes multiple protrusions 4022, multiple protrusions 4022 are arranged on the third sound absorbing body 4021 at intervals, so that the dust collecting member 201 can be effectively supported, the area of ​​the dust collecting member 201 attached to the third sound absorbing body 4021 can be reduced as much as possible, and the size of the airflow space 501 can be increased as much as possible, thereby reducing the flow resistance of the fluid when it flows through the dust collecting member 201 as much as possible.

[0136] See also Fig.13 In some embodiments, at least one protrusion 4022 includes a plurality of ribs 40221, and the plurality of ribs 40221 are arranged in a spaced relationship along a preset direction, so that the second noise reduction structure 402 has a simple structure and is easy to process. For example, the plurality of ribs 40221 are arranged in spaced relationship and in parallel, and the airflow space 501 includes the space between adjacent ribs 40221.

[0137] Exemplarily, the extension direction of the rib 40221 is perpendicular to or intersects with the preset direction.

[0138] For example, the preset direction is as follows Fig.13 The X1 direction in the example is as follows: Fig.13 As shown in the Y1 direction.

[0139] Exemplarily, the preset direction is perpendicular to the protruding direction of the protruding portion 4022. Exemplarily, the protruding direction of the protruding portion 4022 is as follows: Fig.13 As shown in the Z1 direction.

[0140] Exemplarily, the preset direction is perpendicular to the protruding direction of the protruding portion 4022, and the preset direction is the height direction of the dust box 203. Exemplarily, the preset direction is perpendicular to the protruding direction of the protruding portion 4022, and the preset direction is perpendicular to the height direction of the dust box 203. Exemplarily, the height direction of the dust box 203 is as shown in FIG. Fig.12 The X1 direction is shown in the figure.

[0141] Exemplarily, the shape and / or size of the rib 40221 can be set according to actual needs. For example, the shape of the rib 40221 includes a straight shape or a curved shape.

[0142] See also Fig.14 , at least one protrusion 4022 includes a plurality of bosses 40222, and the plurality of bosses 40222 are arranged at intervals, and the plurality of bosses 40222 are arranged in an array. Exemplarily, the plurality of bosses 40222 form at least one boss array 40223, and each boss array 40223 includes at least one boss 40222, and the boss arrays 40223 are arranged at intervals, so that the dust collecting member 201 can be effectively supported as much as possible, the area of ​​the dust collecting member 201 attached to the third sound absorbing body 4021 can be reduced as much as possible, and the size of the airflow space 501 can be increased as much as possible, thereby reducing the flow resistance of the airflow when passing through the dust collecting member 201 as much as possible. Exemplarily, the boss arrays 40223 are arranged at intervals and in parallel. Exemplarily, the boss arrays 40223 are arranged at intervals along the above-mentioned preset direction.

[0143] The size or protruding height of the protruding portion 4022 can be set according to actual needs, for example, the protruding height of the protruding portion 4022 ranges from 2mm to 20mm, for example, the protruding height of the protruding portion 4022 is 2mm, 5mm, 10mm, 15mm, 20mm or any value between 2mm and 20mm, so that the flow resistance of the airflow when passing through the dust collecting member 201 can be effectively reduced, and the space occupied by the second noise reduction structure 402 can be reduced, thereby increasing the capacity of the dust collecting member 201. If the protruding height of the protruding portion 4022 is less than 2mm, it is difficult for the protruding portion 4022 to provide a good supporting effect on at least part of the dust collecting member 201, and thus it is difficult to prevent the dust collecting member 201 from being closely attached to the third sound absorbing body 4021, thereby making it difficult to effectively reduce the flow resistance of the airflow when passing through the dust collecting member 201, and further making it difficult to effectively reduce the noise of the airflow when passing through the dust collecting member 201. If the protruding height of the protruding portion 4022 is greater than 20 mm, the second noise reduction structure 402 occupies a large space and has a large weight, which is not conducive to increasing the capacity of the dust collecting member 201 and is not conducive to achieving miniaturization and lightweight design.

[0144] See also Fig.12In some embodiments, the dust box 203 includes a first box shell 2034, a second box shell 2035 and a sealing member 2036.

The setting of the sealing member 2036 can achieve the sealing of the connection between the first box shell 2034 and the second box shell 2035; in addition, the sealing member 2036 can also play a certain role in sound insulation. In addition, the second box shell 2035 is detachably connected to the first box shell 2034, so that the first box shell 2034 and the second box shell 2035 can be easily disassembled and assembled, and the dust collecting member 201 in the dust box 203 can be easily replaced or cleaned.

[0145] Exemplarily, the detachable connection methods between the first box shell 2034 and the second box shell 2035 include: snap connection, magnetic connection, screw locking connection, etc.

[0146] See also Fig.15 and Fig.16 In some embodiments, the wind guide structure 300 is used as a channel for conveying airflow, and the wind guide structure 300 includes a first wind guide channel section 303 and a second wind guide channel section 304, and at least part of the first wind guide channel section 303 and at least part of the second wind guide channel section 304 are connected in sequence along the airflow direction; the noise reduction structure 400 is arranged on the outer wall of at least part of the first wind guide channel section 303, and the flow channel area of ​​the first wind guide channel section 303 is smaller than the flow channel area of ​​the second wind guide channel section 304.

[0147] Exemplarily, the noise reduction structure 400 includes a third noise reduction structure 403 , and the third noise reduction structure 403 is disposed on at least a portion of the outer wall of the first air guiding channel section 303 .

[0148] It is understandable that if the third noise reduction structure 403 is disposed in the air guide structure 300, the third noise reduction structure 403 will occupy a certain amount of the air guide channel, thereby increasing the flow resistance of the air guide channel. The purpose of setting the third noise reduction structure 403 is to absorb or silence sound, but since the third noise reduction structure 403 occupies the area of ​​the air guide channel, the flow resistance of the airflow increases, the noise increases, and the working power of the power component 100 used to provide driving force for dirt increases, thereby increasing the noise to a certain extent, making the final noise reduction effect not obvious.

[0149] In the air guide structure 300 of the above-mentioned embodiment, since the third noise reduction structure 403 is arranged on the outer wall of at least part of the first air guide channel section 303, the third noise reduction structure 403 can absorb the noise generated when the airflow flows through the first air guide channel section 303 to a certain extent, thereby reducing the noise output to the outside when the base station 1000 collects dust and improving the user experience; in addition, since the third noise reduction structure 403 is arranged on the outer wall of at least part of the first air guide channel section 303, it is possible to reduce or avoid the area of ​​the first air guide channel section 303 occupied by the third noise reduction structure 403 as much as possible, thereby reducing the flow resistance of the airflow flowing through the first air guide channel section 303, realizing low flow resistance noise reduction, and effectively reducing the working power required by the power component 100 when the base station 1000 collects dust, thereby reducing the noise at the source, and further effectively improving the overall noise reduction effect of the base station 1000 when collecting dust, further reducing the noise output to the outside when the base station 1000 collects dust, and saving energy and protecting the environment.

[0150] See also Fig.16 In some embodiments, the third noise reduction structure 403 is wrapped around at least part of the outer wall of the first air guide channel section 303. In this way, the area of ​​the air guide structure 300 surrounded by the third noise reduction structure 403 in the circumferential direction can be increased as much as possible without occupying the area of ​​the air guide channel in the air guide structure 300. When the airflow flows through the air guide structure 300, the third noise reduction structure 403 can reduce the noise propagation to the outside of the air guide structure 300 in multiple directions of the air guide structure 300, thereby further reducing the noise output to the outside when the base station 1000 collects dust, and further improving the user experience of the base station 1000.

[0151] See also Fig.16 In some embodiments, the third noise reduction structure 403 includes a fourth sound absorbing body 4031, and the first air guide channel section 303 is formed with an opening 3033 for sound to be transmitted to the fourth sound absorbing body 4031. The fourth sound absorbing body 4031 is arranged on the outer wall of the portion of the first air guide channel section 303 where the opening 3033 is arranged; wherein the fourth sound absorbing body 4031 includes at least one of foam cotton, sound absorbing cotton, pearl cotton, felt, etc. Noise can be reflected and consumed in the opening 3033 of the first air guide channel section 303, thereby reducing the noise generated when the airflow passes through the first air guide channel section 303; in addition, the fourth sound absorbing body 4031 can absorb the sound energy transmitted from the opening 3033 to the outside of the first air guide channel section 303, thereby further reducing the noise generated when the airflow passes through the first air guide channel section 303, so as to effectively improve the overall noise reduction effect of the base station 1000 and improve the user experience of the base station 1000. Please refer to Fig.16In some embodiments, the first air guide channel section 303 includes a first channel sub-section 3031 and a second channel sub-section 3032 connected in sequence along the air flow direction; the outer wall of the second channel sub-section 3032 is provided with at least part of the third noise reduction structure 403. One end of the first channel sub-section 3031 is used to connect with an upstream component, such as the second air guide channel section 304, the power assembly 100 or the dust box 2001 of the cleaning robot 2000, and the other end of the first channel sub-section 3031 is used to connect with the second channel sub-section 3032; one end of the second channel sub-section 3032 is used to connect with the first channel sub-section 3031, and the second channel sub-section 3032 is used to connect with the second air guide channel section 304. The first channel sub-segment 3031 of the first air guide channel segment 303 located at the most upstream of the air flow direction is used to connect to the dust box 2001 of the power assembly 100 or the cleaning robot 2000, and the first channel sub-segment 3031 of the remaining first air guide channel segment 303 is used to connect to the second air guide channel segment 304 located upstream of the second channel sub-segment 3032 corresponding to the first air guide channel segment 303.

[0152] Exemplarily, the second channel sub-segment 3032 of each first air guiding channel segment 303 is formed with an opening 3033 for sound transmission to the third noise reduction structure 403 , and the outer wall of the second channel sub-segment 3032 of each first air guiding channel segment 303 is provided with at least a portion of the third noise reduction structure 403 .

[0153] See also Fig.16 In some embodiments, the outer wall of the second channel sub-segment 3032 is provided with at least part of the third noise reduction structure 403, and the flow channel area of ​​at least part of the first air guide channel segment 303 along the air flow direction remains unchanged, that is, the flow channel area of ​​the part of the first air guide channel segment 303 wrapped with the third noise reduction structure 403 along the air flow direction remains unchanged, so as to facilitate the provision of a third noise reduction structure 403 with a larger wrapped area, and the structure of the third noise reduction structure 403 is simple and easy to process. Exemplarily, the flow channel area of ​​the second channel sub-segment 3032 along the air flow direction remains unchanged. In other embodiments, the flow channel area of ​​the second channel sub-segment 3032 along the air flow direction may also be changed, which is not limited here. The outer wall of the second channel sub-segment 3032 is provided with at least part of the third noise reduction structure 403, including: part of the third noise reduction structure 403 is provided on the outer wall of the second channel sub-segment 3032, and the other part of the third noise reduction structure 403 is provided on the first channel sub-segment 3031; the third noise reduction structure 403 is provided on the outer wall of the second channel sub-segment 3032.

[0154] See also Fig.16In some embodiments, the third noise reduction structure 403 further includes a noise reduction shell 4032, which is disposed on the outside of the fourth sound absorbing body 4031, and the fourth sound absorbing body 4031 is disposed between the noise reduction shell 4032 and the second channel sub-segment 3032. The noise reduction shell 4032 can reduce or block the noise from being transmitted to the outside of the noise reduction shell 4032 to a certain extent, thereby achieving a better noise reduction effect. Exemplarily, the noise reduction shell 4032 is sleeved outside the fourth sound absorbing body 4031, and the fourth sound absorbing body 4031 is sleeved outside the second channel sub-segment 3032. Exemplarily, the noise reduction shell 4032 is connected to one of the fourth sound absorbing body 4031, the first channel sub-segment 3031, the second channel sub-segment 3032, and the second wind guide channel segment 304.

[0155] See also Fig.16 and Fig.17 In some embodiments, the flow channel area of ​​the first air guide channel segment 303 is smaller than the flow channel area of ​​the second air guide channel segment 304, so that the first air guide channel segment 303 cooperates with the second air guide channel segment 304 to form an expansion type of noise elimination structure, realizes resistive noise elimination, and effectively reduces noise. Exemplarily, the flow channel area of ​​the second channel sub-segment 3032 along the flow direction of the airflow remains unchanged, and the flow channel area of ​​the second channel sub-segment 3032 is smaller than the flow channel area of ​​the second air guide channel segment 304. When the sound wave propagates from the second channel sub-segment 3032 of equal flow channel area to the second air guide channel segment 304, it will encounter a cross-sectional mutation of a certain length, causing the sound wave to rebound due to impedance mismatch, so that part of the sound wave no longer propagates forward in the flow direction of the airflow, thereby obtaining a good resistive noise elimination effect, effectively reducing noise and saving power consumption.

[0156] Exemplarily, the flow area of ​​the second air guiding channel segment 304 or the flow area of ​​the first air guiding channel segment 303 is greater than or equal to 1.5 times the flow area of ​​the second channel sub-segment 3032, so as to take into account both a smaller volume and a good resistive sound-absorbing effect.
