[0073] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0075] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0077] 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.

[0078] To this end, the utility model provides a power component, a dust collecting device, a base station and a cleaning system to reduce the noise output by the base station when collecting dirt and improve the user experience.

[0079] 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.

[0080] See also Figure 1 The utility model provides a dust collecting device 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.

[0081] See also Figure 1 In some embodiments, the target object is the cleaning robot 2000, and the dust collecting device 1001 can collect dirt from the cleaning robot 2000 to ensure that the cleaning robot 2000 can perform normal cleaning work. Figure 1Exemplarily, the cleaning robot 2000 includes a dust box 2001, and the dust collecting device 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 accommodate the dirt, thereby providing a guarantee for the cleaning robot 2000 to perform normal cleaning work later.

[0082] See also Figure 1 In some embodiments, the dust collecting device 1001 includes a power assembly 100 and a dust collecting assembly 200, wherein the power assembly 100 is used to drive the dirt to be transferred to the dust collecting assembly 200, and the dust collecting assembly 200 is used to contain the dirt. Exemplarily, the power assembly 100 can generate negative pressure in the dust collecting channel of the dust collecting device 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 collecting assembly 200; when the airflow including the dirt is transported to the dust collecting assembly 200, the dirt can be collected at the dust collecting assembly 200, and the airflow can be output from the dust collecting assembly 200. Exemplarily, the power assembly 100 includes at least one of the following: a fan, a pump. Exemplarily, the dust collecting assembly 200 includes a dust collecting box and / or a dust collecting bag.

[0083] See also Figure 2 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 air duct 30. The air duct 30 is used to communicate with the dust collection component 200 of the base station 1000; the noise reduction structure 40 is disposed outside the air duct 30.

[0084] It can be understood that the purpose of setting up the noise reduction structure 40 is to absorb or silence sound. If the noise reduction structure 40 is set in the air duct 30, the noise reduction structure 40 will occupy a certain area of ​​the air duct 30, so that the flow resistance of the air duct 30 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.

[0085] In the power assembly 100 of the above embodiment, the noise reduction structure 40 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 noise reduction structure 40 is arranged outside the air duct 30, the noise reduction structure 40 will not block the 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.

[0086] Exemplarily, the 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.

[0087] 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.

[0088] For example, the radial direction of the power assembly 100 is perpendicular to Figure 3 The X direction in .

[0089] Exemplarily, the radial direction of the power assembly 100 is perpendicular to the axial direction of the power assembly 100 .

[0090] For example, the radial direction of the power assembly 100 refers to the direction of the airflow in the air duct 30 ( Figure 3 The direction is perpendicular to the direction indicated by the thick dashed arrow.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] Exemplarily, the axial direction of the power assembly 100 is perpendicular to the radial direction of the power assembly 100 .

[0097] For example, the axial direction of the power assembly 100 is Figure 3 Parallel to the X direction.

[0098] Exemplarily, the axial direction of the power assembly 100 is parallel to the flow direction of the airflow in the air duct 30 .

[0099] 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 300.

[0100] 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 300.

[0101] See also Figure 6 , combined with Figure 3In some embodiments, the noise reduction structure 40 includes a sound insulation cavity 41 disposed outside the 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 41. 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 41 (the medium includes at least one of gas, solid and liquid) is not easy or will not leak out of the soundproof cavity 41 through the connection between the two, or the medium outside the soundproof cavity 41 is not easy or will not enter the soundproof cavity 41 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 41 (the medium includes at least one of gas, solid and liquid) is not easy or will not leak out of the soundproof cavity 41 through the connection between the two, or the medium outside the soundproof cavity 41 is not easy or will not enter the soundproof cavity 41 through the connection between the two. The sealed connection at other positions of the present invention is similar, and will not be repeated here.

[0102] See also Figure 6 , and combined with Figure 3 In some embodiments, the wall of the soundproof cavity 41 wraps at least part of the fan module 20. The soundproof cavity 41 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 41 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 collecting device 1001 can normally collect dirt. The wall of the soundproof cavity 41 can completely wrap the fan module 20; or, the soundproof cavity 41 partially wraps the fan module 20, for example, the soundproof cavity 41 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 41 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.

[0103] See also Figure 6 , and combined with Figure 3In some embodiments, along the axial direction of the power assembly, 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 41 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 41 larger, and the vibration reduction and sound insulation effect of the entire power assembly 100 better.

[0104] See also Figure 6 In some embodiments, the soundproof cavity 41 is empty, and the air layer or dielectric layer in the soundproof cavity 41 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 41, 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.

[0105] See also Figure 7 In some embodiments, a first sound absorbing body 42 is provided in the soundproof cavity 41. The first sound absorbing body 42 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 42, 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 42 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.

[0108] 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.

[0109] 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 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 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 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.

[0110] It can be understood that the air outlet 32 ​​of the air duct 30 is formed in at least one of the housing structure 10 and the fourth vibration damper 142, which may include: the air outlet 32 ​​of the air duct 30 is formed in the housing structure 10, and the air outlet 32 ​​of the air duct 30 is communicated with the duct assembly 300; or, the air outlet 32 ​​of the air duct 30 is formed in the fourth vibration damper 142, and the air outlet 32 ​​of the air duct 30 is communicated with the duct assembly 300; or, the air outlet 32 ​​of the air duct 30 is formed in the housing structure 10 and the fourth vibration damper 142, and the air outlet 32 ​​of the air duct 30 is communicated with the duct assembly 300. Exemplarily, the air outlet 32 ​​of the air duct 30 is formed in the first housing 11, and the air outlet 32 ​​of the 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 air duct 30 , which is not limited here.

[0111] See also Figure 3 In some embodiments, the air inlet 31 of the air duct 30 is formed on the third vibration damper 141, and the air outlet 32 ​​of the 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] See also Figure 8 and Fig.10 In some embodiments, the housing of the dust collecting assembly 200 has an air outlet F, and a mounting portion 201 is detachably provided at the air outlet F of the dust collecting assembly 200, and the second vibration damping 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 201 of the dust collecting assembly 200 squeezes the flange 1415 of the second vibration damping section 1413 between the mounting portion 201 and the housing of the dust collecting assembly 200, so as to achieve the connection between the second vibration damping section 1413 and the dust collecting assembly 200. Since the mounting portion 201 squeezes the second vibration damping section 1413, that is, the mounting portion 201 and the second vibration damping section 1413 are in interference fit, the sealing of the connection between the mounting portion 201 and the second vibration damping section 1413 can be achieved. Exemplarily, the mounting portion 201 and the end of the second vibration damping section 1413 away from the first vibration damping 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.

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.

[0120] See also Figure 3In some embodiments, the shell structure 10 includes a first shell 11, and the fan module 20 is disposed in the first shell 11. The noise reduction structure 40 includes a second sound absorbing body 43, and the second sound absorbing body 43 is disposed between the first shell 11 and the fan module 20 along the radial direction of the power assembly 100. The second sound absorbing body 43 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 43 is disposed outside the air duct 30, and the second sound absorbing body 43 will not block the air duct 30, so that low flow resistance noise reduction can be achieved, and the working power required by the fan module 20 can be effectively reduced. The reduction in 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.

[0121] See also Figure 3 In some embodiments, the second sound absorbing body 43 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 43. Exemplarily, the second sound absorbing body 43 may completely wrap the circumferential side wall of the fan module 20; or, the second sound absorbing body 43 partially wraps the fan module 20. In the case where the second sound absorbing body 43 partially wraps the fan module 20, the wrapping area of ​​the second sound absorbing body 43 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 43 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.

[0122] See also Figure 3 , Figure 6 and Figure 7In some embodiments, the shell structure 10 includes a first shell 11, the fan module 20 is disposed in the first shell 11, and the noise reduction structure 40 includes a sound insulation cavity 41, which is formed in the shell structure 10. The noise reduction structure 40 also includes a second sound absorbing body 43, which is disposed between the first shell 11 and the fan module 20 along the radial direction of the power assembly 100, and the cavity wall of the sound insulation cavity 41 is at least partially wrapped outside the second sound absorbing body 43. The sound insulation cavity 41 and the second sound absorbing body 43 can cooperate to reduce the noise in the first shell 11 (the noise includes at least one of the following: the noise generated by the fan module 20, the noise generated by the airflow passing through the air duct 30), achieve double noise reduction, and improve 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 air duct 30 is first attenuated by the second sound-absorbing body 43, then attenuated by the first shell 11, and then attenuated by the medium layer in the sound insulation cavity 41 or the first sound-absorbing body 42, 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.

[0123] In some embodiments, the first sound absorbing body 42 and / or the second sound absorbing body 43 can be made of any suitable material.

[0124] See also Fig.11 In some embodiments, the dust collecting device 1001 further includes a pipe assembly 300, and the pipe assembly 300 is used to connect the power assembly 100 or the dust collecting assembly 200. For example, the pipe assembly 300 is used to connect the power assembly 100, and the airflow discharged from the power assembly 100 can be discharged through the pipe assembly 300. For another example, the pipe assembly 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 pipe assembly 300, and the airflow discharged from the dust collecting assembly 200 can be transported to the power assembly 100.

[0126] It can be understood that the purpose of setting up the noise reduction structure 40 is to absorb or silence sound. If the noise reduction structure 40 is set in the air duct 30, the noise reduction structure 40 will occupy a certain area of ​​the air duct 30, so that the flow resistance of the air duct 30 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.

[0127] In the base station 1000 of the above embodiment, the noise reduction structure 40 can reduce the noise generated by the fan module 20 when it is working and propagate outward, thereby reducing the noise. In addition, since the noise reduction structure 40 is arranged outside the air duct 30, the noise reduction structure 40 will not block the 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.

[0130] It can be understood that the purpose of setting up the noise reduction structure 40 is to absorb or silence sound. If the noise reduction structure 40 is set in the air duct 30, the noise reduction structure 40 will occupy a certain area of ​​the air duct 30, so that the flow resistance of the air duct 30 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.

[0131] In the cleaning system of the above embodiment, the noise reduction structure 40 can reduce the noise generated by the fan module 20 when it is working and propagate outward, thereby reducing the noise. In addition, since the noise reduction structure 40 is arranged outside the air duct 30, the noise reduction structure 40 will not block the 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.
