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.

[0056] 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.

[0057] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0058] With the continuous development of cleaning robots, base stations used in conjunction with cleaning robots have emerged. After the dust box of the cleaning robot collects a certain amount of dirt, the base station can transfer the dirt in the dust box of the cleaning robot to the base station, thereby ensuring that the dust box of the cleaning robot can continue to hold the dirt, providing a guarantee for the cleaning robot to be able to perform normal cleaning work in the future. However, the base station in the related art generates a lot of noise when collecting dirt in the dust box of the cleaning robot, which affects the user experience.

[0059] To this end, the utility model provides an air duct structure, 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.

[0060] 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.

[0061] See also Figure 1 The utility model provides a base station 1000, 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.

[0062] See also Figure 1 In some embodiments, the base station 1000 can collect dirt from the cleaning robot 2000 to ensure that the cleaning robot 2000 can perform normal cleaning work. Figure 1 Exemplarily, the cleaning robot 2000 includes a dust box 2001, and the base station 1000 can collect or transfer the dirt in the dust box 2001 to the base station 1000, 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.

[0063] See also Figure 1 In some embodiments, the base station 1000 includes an air duct structure 100, a dust collecting assembly 200 and a power assembly 300. The air duct structure 100 is connected to the dust collecting assembly 200 or the power assembly 300, and the air inlet of the power assembly 300 is connected to the dust collecting assembly 200. In some embodiments, the dust collecting assembly 200 is used to contain dirt. Exemplarily, the dust collecting assembly 200 includes a dust collecting box and / or a dust collecting bag.

[0064] In some embodiments, the power assembly 300 is used to drive the dirt to be transferred to the dust collection assembly 200 of the base station 1000. Exemplarily, the power assembly 300 can generate a suction airflow to exhaust air in the dust box 2001 of the cleaning robot 2000, so that a negative pressure is generated in the dust box 2001, thereby allowing the dirt in the dust box 2001 of the cleaning robot 2000 or dirt in other areas to be sucked to the dust collection assembly 200; when the airflow containing 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 300 includes at least one of the following: a fan, a pump.

[0065] See also Figure 2 and Figure 3In some embodiments, the base station 1000 includes a duct structure 100, the duct structure 100 includes a duct body 10 and a sound absorbing structure 20, the duct body 10 is used as a channel for conveying airflow, the duct body 10 includes a first duct segment 11 and a second duct segment 12, at least part of the first duct segment 11 and at least part of the second duct segment 12 are connected in sequence along the airflow direction; the sound absorbing structure 20 is arranged on the outer wall of at least part of the first duct segment 11, and the flow area of ​​the first duct segment 11 is smaller than the flow area of ​​the second duct segment 12.

[0066] It is understandable that if the sound absorbing structure 20 is disposed in the air duct body 10, the sound absorbing structure 20 will occupy a certain area of ​​the air duct, thereby increasing the flow resistance of the air duct. The purpose of setting the sound absorbing structure 20 is to absorb or silence sound, but since the sound absorbing structure 20 occupies the area of ​​the air duct, the flow resistance of the airflow increases, the noise increases, and the working power of the power component 300 used to provide driving force for dirt increases, thereby increasing the noise to a certain extent, making the final noise reduction effect not obvious.

[0067] In the air duct structure 100 of the above-mentioned embodiment, since the sound-absorbing structure 20 of the air duct structure 100 is arranged on the outer wall of at least part of the first air duct section 11, the sound-absorbing structure 20 can absorb the noise generated when the airflow passes through the first air duct section 11 and the air duct main body 10 to a certain extent, thereby reducing the noise output to the outside when the base station 1000 collects dust and improves the user experience; in addition, since the sound-absorbing structure 20 is arranged on the outer wall of at least part of the first air duct section 11, the area of ​​the air duct (the air duct is used for airflow to flow through) of the first air duct section 11 occupied by the sound-absorbing structure 20 can be reduced or avoided as much as possible, thereby reducing the flow resistance of the airflow passing through the first air duct section 11 and the air duct main body 10, achieving low flow resistance noise reduction, and effectively reducing the working power required by the power component 300 when the base station 1000 collects dust, thereby reducing the noise at the source, and then 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.

[0068] See also Figure 3 In some embodiments, the sound absorbing structure 20 is wrapped around at least part of the outer wall of the first air duct segment 11. In this way, the area of ​​the air duct body 10 surrounded by the sound absorbing structure 20 in the circumferential direction can be increased as much as possible without occupying the area of ​​the air duct in the air duct body 10. When the airflow flows through the air duct body 10, the sound absorbing structure 20 can reduce the noise propagation to the outside of the air duct structure 100 in multiple directions of the air duct body 10, thereby further reducing the noise output to the outside when the base station 1000 collects dust, thereby further improving the user experience of the base station 1000.

[0069] See also Figure 3In some embodiments, the sound absorbing structure 20 includes a first sound absorbing member 21, and the first air duct segment 11 is formed with an opening 113 for sound to be transmitted to the first sound absorbing member 21. The first sound absorbing member 21 is arranged on the outer wall of the portion of the first air duct segment 11 where the opening 113 is arranged; wherein the first sound absorbing member 21 includes at least one of foam cotton, sound absorbing cotton, pearl cotton, felt, etc. Noise can be reflected and consumed in the opening 113 of the first air duct segment 11, thereby reducing the noise generated when the airflow passes through the first air duct segment 11; in addition, the first sound absorbing member 21 can absorb the sound energy transmitted from the opening 113 to the outside of the first air duct segment 11, thereby further reducing the noise generated when the airflow passes through the first air duct segment 11, 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 Figure 3 In some embodiments, the first air duct segment 11 includes a first air duct sub-segment 111 and a second air duct sub-segment 112 connected in sequence along the air flow direction; the outer wall of the second air duct sub-segment 112 is provided with at least a portion of the sound absorbing structure 20. One end of the first air duct sub-segment 111 is used to connect with an upstream component, such as the dust box 2001 used to connect to the second air duct segment 12, the power assembly 300 or the cleaning robot 2000, and the other end of the first air duct sub-segment 111 is used to connect with the second air duct sub-segment 112; one end of the second air duct sub-segment 112 is used to connect with the first air duct sub-segment 111, and the second air duct sub-segment 112 is used to connect with the second air duct segment 12. The first air duct sub-segment 111 of the first air duct segment 11 located at the most upstream of the air flow direction is used to connect to the dust box 2001 of the power assembly 300 or the cleaning robot 2000, and the first air duct sub-segments 111 of the remaining first air duct segments 11 are used to connect to the second air duct segment 12 located upstream of the second air duct sub-segment 112 corresponding to the first air duct segment 11.

[0070] In some embodiments, the sound absorbing structure 20 is provided in at least one of the first air duct sub-segment 111 and the second air duct sub-segment 112. The outer wall of the first air duct sub-segment 111 may be provided with a portion of the sound absorbing structure 20, or may not be provided with the sound absorbing structure 20. When the number of the first air duct segments 11 includes multiple, the first air duct sub-segments 111 of different first air duct segments 11 may be provided with or not provided with a portion of the sound absorbing structure 20 according to actual needs. For example, the second air duct sub-segment 112 of each first air duct segment 11 is formed with an opening 113 for sound to be transmitted to the sound absorbing structure 20, and the outer wall of the second air duct sub-segment 112 of each first air duct segment 11 is provided with at least a portion of the sound absorbing structure 20;

[0071] The first air duct sub-segment 111 of the first air duct segment 11 located most upstream in the air flow direction is not provided with an opening 113, and the outer wall of the first air duct sub-segment 111 of the most upstream first air duct segment 11 is not provided with a sound absorbing structure 20; the first air duct sub-segments 111 of the remaining first air duct segments 11 are also provided with openings 113, and at least part of the sound absorbing structure 20 is provided on the outer wall of the first air duct sub-segment 111. The shapes and / or flow channel areas of the first air duct sub-segments 111 of different first air duct segments 11 may be the same or different, and are not limited here.

[0072] See also Figure 3 In some embodiments, at least part of the sound absorbing structure 20 is provided on the outer wall of the second air duct sub-segment 112, and the flow area of ​​at least part of the first air duct segment 11 along the airflow direction remains unchanged, that is, the flow area of ​​the part of the first air duct segment 11 wrapped with the sound absorbing structure 20 along the airflow direction remains unchanged, so as to facilitate the provision of a sound absorbing structure 20 with a larger wrapped area, and the structure of the sound absorbing structure 20 is simple and easy to process. Exemplarily, the flow area of ​​the second air duct sub-segment 112 along the airflow direction remains unchanged. In other embodiments, the flow area of ​​the second air duct sub-segment 112 along the airflow direction may also be changed, which is not limited here. At least part of the sound absorbing structure 20 is provided on the outer wall of the second air duct sub-segment 112, including: part of the sound absorbing structure 20 is provided on the outer wall of the second air duct sub-segment 112, and the other part of the sound absorbing structure 20 is provided on the first air duct sub-segment 111; the sound absorbing structure 20 is provided on the outer wall of the second air duct sub-segment 112.

[0073] See also Figure 3 In some embodiments, the sound absorbing structure 20 further includes a shell 22, which is disposed outside the first sound absorbing member 21, and the first sound absorbing member 21 is disposed between the shell 22 and the second air duct sub-segment 112. The shell 22 can reduce or block the noise from being transmitted to the outside of the shell 22 to a certain extent, thereby achieving a better effect of reducing noise. Exemplarily, the shell 22 is sleeved outside the first sound absorbing member 21, and the first sound absorbing member 21 is sleeved outside the second air duct sub-segment 112. Exemplarily, the shell 22 is connected to one of the first sound absorbing member 21, the first air duct sub-segment 111, the second air duct sub-segment 112, and the second air duct segment 12.

[0074] See also Figure 3 and Figure 4In some embodiments, the flow area of ​​the first air duct segment 11 is smaller than the flow area of ​​the second air duct segment 12, so that the first air duct segment 11 and the second air duct segment 12 cooperate to form an expansion type of muffler structure, realize resistive muffler, and effectively reduce noise. Exemplarily, the flow area of ​​the second air duct sub-segment 112 along the flow direction of the airflow remains unchanged, and the flow area of ​​the second air duct sub-segment 112 is smaller than the flow area of ​​the second air duct segment 12. When the sound wave propagates from the second air duct sub-segment 112 of equal flow area to the second air duct segment 12, 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 muffler effect, effectively reducing noise and saving power consumption.

[0075] Exemplarily, the flow area of ​​the second air duct segment 12 or the flow area of ​​the first air duct segment 11 is greater than or equal to 1.5 times the flow area of ​​the second air duct sub-segment 112, so as to take into account both a smaller volume and a good resistive sound-absorbing effect.

[0076] The number of the first air duct segment 11 and the second air duct segment 12 can be designed according to actual needs, and the number of the first air duct sub-segment 111, the second air duct sub-segment 112 and the second air duct segment 12 can be designed according to actual needs. In some embodiments, the number of the first air duct segment 11 and the second air duct segment 12 is the same; or, the number of the first air duct sub-segment 111, the second air duct sub-segment 112 and the second air duct segment 12 is the same. In other embodiments, the number of the first air duct segment 11 and the second air duct segment 12 is different, and the number of the first air duct sub-segment 111, the second air duct sub-segment 112 and the second air duct segment 12 is different.

[0077] See also Figure 4 In some embodiments, the number of the second air duct sub-segment 112 and the second air duct segment 12 are both one, and the second air duct sub-segment 112 and the second air duct segment 12 are connected in sequence along the air flow direction. In this way, the air duct structure 100 has a simple structure and a good noise reduction effect.

[0078] See also Figure 4 In some embodiments, the number of the first air duct segment 11 and the second air duct segment 12 are both one, and the first air duct segment 11 and the second air duct segment 12 are connected in sequence along the air flow direction. In this way, the air duct structure 100 has a simple structure and a good noise reduction effect.

[0079] See also Figure 5In some embodiments, the number of the first air duct segments 11 is the same as the number of the second air duct segments 12. The number of the first air duct segments 11 includes multiple (such as two, three or more), and the multiple first air duct segments 11 and the multiple second air duct segments 12 are alternately connected along the air flow channel direction. In this way, multiple expansion-type noise reduction structures can be formed to improve the effect of resistance noise reduction, thereby effectively reducing noise. Please refer to Figure 5 Exemplarily, the number of the first air duct segments 11 includes two, the number of the second air duct segments 12 includes two, and the two first air duct segments 11 and the two second air duct segments 12 are alternately connected along the air flow channel direction.

[0080] See also Figure 6 In some embodiments, one end of at least one first air duct segment 11 is connected to a second air duct segment 12, and the other end of the first air duct segment 11 is connected to another second air duct segment 12; the first air duct segment 11 connected to two of the second air duct segments 12 is inserted into the second air duct segment 12 located upstream of the first air duct segment 11, so that space can be saved and a better resistance and sound elimination effect can be achieved.

[0081] See also Figure 6 or Figure 7 In some embodiments, the air duct structure 100 further includes a second sound absorbing member 23, which is disposed on the outer wall of the second air duct segment 12. The second sound absorbing member 23 can reduce the noise generated when the airflow passes through the second air duct segment 12, thereby further improving the noise reduction effect and improving the user experience of the base station 1000.

[0082] The thickness of the first sound absorbing member 21 and / or the second sound absorbing member 23 can be set according to actual needs. For example, the thickness range is [5mm, 30mm], that is, the thickness is 5mm, 10mm, 20mm, 30mm or any other suitable value between 5mm-30mm, so as to take into account a smaller volume and a good noise reduction effect.

[0083] For example, the thickness of the shell 22 may be greater than or equal to 3 mm. The thickness of the first sound absorbing member 21 may be greater than or equal to 10 mm. The lengths of the shell 22 and the first sound absorbing member 21 may be greater than 100 mm.

[0084] The materials of the first sound absorbing member 21 and / or the second sound absorbing member 23 can be set according to actual needs. For example, the first sound absorbing member 21 and / or the second sound absorbing member 23 include at least one of foamed cotton, sound absorbing cotton, pearl cotton, felt, etc. In this way, the sound absorbing structure 20 has a low price and a good sound absorbing effect. It can be understood that 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.

[0085] For example, Figures 4 to 7 The dashed arrows in the figure indicate the flow direction of the airflow.

[0086] See also Figure 2 and Figure 3 In some embodiments, the air duct structure 100 further includes a shock absorber 30, which is disposed at one end of the first air duct section 11 away from the second air duct section 12. The shock absorber 30 can reduce vibration, reduce the transmission of vibration between the air duct structure 100 and other components connected thereto, and realize a shock-absorbing connection between the air duct structure 100 and other components. Exemplarily, the first air duct section 11 located at the most upstream of the air flow direction is used to connect with the power assembly 300 of the base station 1000, and the shock absorber 30 is disposed at one end of the first air duct section 11 at the most upstream away from the second air duct section 12. The shock absorber 30 can reduce the transmission of vibration between the air duct structure 100 and the power assembly 300, and realize a shock-absorbing connection between the air duct structure 100 and the power assembly 300, so that the vibration generated by the power assembly 300 during operation is not easily transmitted to the air duct structure 100, further improving the overall noise reduction effect of the base station 1000. Exemplarily, the first air duct section 11 located most upstream in the air flow direction is used to connect with the cleaning robot 2000, and the shock absorber 30 is arranged at one end of the first air duct section 11 most upstream away from the second air duct section 12. The shock absorber 30 can reduce the transmission of vibration between the air duct structure 100 and the cleaning robot 2000.

[0087] Exemplarily, the shock absorbing member 30 may include a flexible structure having flexibility or an elastic structure having elasticity.
