TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning assembly, a cleaning mechanism and a cleaning equipment. BACKGROUND

[0003] In the related art, the cleaning mechanism can include a cleaning assembly, and the cleaning assembly can be used to clean a to-be-cleaned area. However, in the related art, it is difficult for the cleaning equipment to accurately obtain the dirt degree of the to-be-cleaned area, so it is difficult to accurately control the cleaning equipment according to the dirt degree of the to-be-cleaned area.

[0004] Therefore, how to accurately obtain the dirt degree of the to-be-cleaned area has become a problem to be solved in the technical field of cleaning equipment. Invention content

[0005] Embodiments of the present application provide a cleaning assembly, a cleaning mechanism and a cleaning equipment to solve the problem that the cleaning equipment in the related art is difficult to accurately obtain the dirt degree of the to-be-cleaned area.

[0006] The first aspect of the embodiments of the present application provides a cleaning assembly, which includes a shell, a cleaning component, a first damping device, an air duct structure and a dust particle sensor. The shell is used to form a cleaning cavity, and the cleaning component is arranged in the cleaning cavity. The air duct structure is used to form an airflow passage, one end of the air duct structure is connected to the shell through the first damping device, and the cleaning cavity and the airflow passage are connected through the inner cavity of the first damping device. The dust particle sensor is arranged on the air duct structure, and the dust particle sensor is used to detect the concentration of suspended particulate matter in the airflow passage.

[0007] The cleaning assembly provided by the embodiments of the present application can play a role in buffering and absorbing energy through the first damping device, so as to attenuate the vibration and noise transmitted from one side of the shell to the airflow passage. Through the first damping device arranged between the dust particle sensor and the shell, the signal-to-noise ratio of the signal detected by the dust particle sensor arranged on the air duct structure can be improved, so that the vibration and noise on one side of the shell do not easily affect the detection of the dust particle sensor while the dust particle sensor can timely perceive the suspended particulate matter swept out by the cleaning component. This facilitates accurate identification of various particulate matters, and further facilitates accurate and timely acquisition of the dirt degree of the to-be-cleaned area, which is beneficial to accurate and timely control of the cleaning equipment according to the dirt degree of the to-be-cleaned area. In addition, after the signal-to-noise ratio of the signal detected by the dust particle sensor is improved, the difficulty of subsequent processing of the signal detected by the dust particle sensor can be reduced.

[0008] In a possible implementation, the first damping device seals the gap between one end of the air duct structure connecting shell and the shell, so that the air duct structure is sealingly connected to the shell through the first damping device.

[0009] In this way, the dirt such as dust cleaned by the cleaning component is less likely to leak at the first damping device, and the dirt cleaned by the cleaning component is guided into the airflow passage, so that the accuracy of detecting the dirt level of the area to be cleaned is higher. In addition, the collection of the dirt cleaned by the cleaning component is facilitated.

[0010] In a possible implementation, the first damping device includes a first damping member, the first damping member has a ring structure, one end of the first damping member is connected to one end of the air duct structure, and the other end of the first damping member is connected to the shell. The cleaning cavity and the airflow passage are connected through the inner cavity of the first damping member.

[0011] In this way, the structure of the first damping device is relatively simple, occupies less space, and is relatively easy to assemble.

[0012] In a possible implementation, the dust particle sensor is a piezoelectric dust particle sensor.

[0013] In this way, the concentration of the suspended particulate matter in the airflow passage can be detected by sensing the vibration caused by the impact of the suspended particulate matter in the airflow passage. The piezoelectric dust particle sensor is sensitive to fine particulate matter, which facilitates detection under low concentration conditions. In addition, the structure of the piezoelectric dust particle sensor is relatively simple and has low power consumption, which facilitates arrangement in a small-sized cleaning device. In addition, the piezoelectric dust particle sensor can detect the concentration of the suspended particulate matter in the airflow passage by sensing the vibration caused by the impact of the suspended particulate matter on the air duct structure, so that the piezoelectric dust particle sensor can be arranged outside the air duct structure. The arrangement of the dust particle sensor is flexible.

[0014] In a possible implementation, the dust particle sensor is located outside the air duct structure and attached to the surface of the air duct structure. The dust particle sensor is configured to detect the concentration of the suspended particulate matter in the airflow passage according to the vibration caused by the impact of the suspended particulate matter in the airflow passage on the air duct structure.

[0015] In this way, the air tightness of the airflow passage is maintained, so that the dirt is less likely to leak at the dust particle sensor, and the dirt cleaned by the cleaning component is guided into the collection cavity for collection. In addition, the dust particle sensor is assembled more easily without the need for an assembly opening on the air duct structure and plugging the assembly opening.

[0016] In a possible implementation, the cleaning assembly further comprises a second damping device, the second damping device is arranged at the end of the air duct structure away from the shell, the end of the air duct structure away from the shell is used to be connected to the dust box of the cleaning mechanism through the second damping device, and the airflow channel is used to be communicated with the collection cavity formed by the dust box through the inner cavity of the second damping device.

[0017] In this way, the second damping device can play a role of buffering and absorbing energy to attenuate the vibration and noise transmitted from the side of the dust box to the airflow channel, and the signal-to-noise ratio of the signal detected by the dust particle sensor can be improved, so that the vibration and noise on the side of the dust box are less likely to affect the detection of the dust particle sensor, and accurate identification of various particulate matters can be facilitated, and then the degree of dirt of the area to be cleaned can be accurately and timely obtained, and the cleaning equipment can be accurately and timely controlled according to the degree of dirt of the area to be cleaned. In addition, after the signal-to-noise ratio of the signal detected by the dust particle sensor is improved, the difficulty of subsequent processing of the signal detected by the dust particle sensor can be reduced.

[0018] In a possible implementation, the second damping device comprises a second damping member, the second damping member is annular in structure, one end of the second damping member is connected to the end of the air duct structure away from the shell, and the other end of the second damping member is used to be connected to the dust box, and the airflow channel is used to be communicated with the collection cavity through the inner cavity of the second damping member.

[0019] In this way, the structure of the second damping device is relatively simple, occupies a smaller space, and is relatively convenient to assemble.

[0020] In a possible implementation, the second damping device is sealingly connected to the end of the air duct structure away from the shell.

[0021] In this way, the air duct structure and the dust box can be sealingly connected through the second damping device.

[0022] The second aspect of the embodiments of the present application provides a cleaning mechanism, which comprises a dust box and the cleaning assembly of any of the above embodiments. The dust box is used to form a collection cavity, the end of the air duct structure of the cleaning assembly away from the shell of the cleaning assembly is connected to the dust box, and the cleaning cavity formed by the shell is communicated with the collection cavity through the airflow channel formed by the air duct structure.

[0023] In this way, the airflow channel formed by the air duct structure is used not only to detect the concentration of the suspended particulate matters swept out by the cleaning component, but also to flow the dirt swept out by the cleaning component into the collection cavity, so as to facilitate the collection of the dust and other dirt swept out by the cleaning component. In addition, the components of the cleaning equipment can be less and the structure can be relatively simple.

[0024] In a possible implementation, the second damping device of the cleaning assembly is arranged between the end of the air duct structure away from the shell and the dust box, the end of the air duct structure away from the shell is connected to the dust box through the second damping device, and the airflow channel and the collection cavity are connected through the inner cavity of the second damping device.

[0025] In a possible implementation, the second damping device seals the gap between the end of the air duct structure away from the shell and the dust box, so that the air duct structure is connected to the dust box in a sealed manner through the second damping device.

[0026] In this way, the dirt such as dust swept by the cleaning component is less likely to leak out at the second damping device, and the dirt swept by the cleaning component is more easily guided into the collection cavity for collection.

[0027] In a possible implementation, the cleaning mechanism further includes an air pump. The air pump is connected to the dust box at the air suction end, the air suction end of the air pump is connected to the collection cavity, and the air pump is configured to drive the airflow in the airflow channel to flow to the collection cavity.

[0028] In this way, the dirt such as dust swept by the cleaning component can be sucked into the collection cavity by the air pump, so that the dirt such as dust swept by the cleaning component is more easily moved to the collection cavity.

[0029] When the cleaning mechanism includes the second damping device, the second damping device can attenuate the vibration and noise generated by the air pump, and the air pump has less influence on the detection of the dust particle sensor, so that the dust particle sensor can accurately detect the concentration of suspended particulate matter in the airflow channel while the dirt such as dust swept by the cleaning component is sucked into the collection cavity by the air pump, so as to obtain the dirt level of the area to be cleaned in a timely and accurate manner.

[0030] In a possible implementation, the cleaning mechanism further includes a third damping device. The third damping device is arranged between the air suction end of the air pump and the dust box, the air suction end of the air pump is connected to the dust box through the third damping device, and the air suction end of the air pump is connected to the collection cavity through the inner cavity of the third damping device.

[0031] In this way, the third damping device can act as a buffer to absorb energy, so as to attenuate the vibration and noise transmitted from the air pump side to the airflow channel, improve the signal-to-noise ratio of the signal detected by the dust particle sensor, and prevent the vibration and noise from the air pump side from affecting the detection of the dust particle sensor, so as to facilitate accurate identification of various particulate matters, accurate and timely acquisition of the dirt level of the area to be cleaned, and accurate and timely control of the cleaning equipment according to the dirt level of the area to be cleaned. In addition, after the signal-to-noise ratio of the signal detected by the dust particle sensor is improved, the difficulty of subsequent processing of the signal detected by the dust particle sensor is reduced.

[0032] The third aspect of the embodiments of the present application provides a cleaning device, which comprises a machine body and the cleaning mechanism in any of the above embodiments, and the cleaning mechanism is arranged on the machine body. BRIEF DESCRIPTION OF DRAWINGS

[0046] The terms used in the embodiments of the present application are only used for explaining the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail in conjunction with the drawings.

[0047] This application provides a cleaning device, which may include, but is not limited to, a robotic vacuum cleaner, a vacuum cleaner, etc. This application uses a robotic vacuum cleaner as an example for illustration.

[0048] In this embodiment, the cleaning device includes a cleaning mechanism and a body. The cleaning mechanism is mounted on the body, which supports components such as the cleaning mechanism. The cleaning mechanism is used to perform the cleaning function.

[0049] In some examples, the body can be a self-moving body, which can drive the cleaning mechanism to move on its own to achieve automatic cleaning of the area to be cleaned.

[0050] In other examples, the body can also be a body that can be moved manually by the user.

[0051] Figure 1 This is a schematic diagram of a cleaning mechanism provided in an embodiment of this application.

[0052] like Figure 1 As shown in the embodiment of this application, the cleaning mechanism includes a cleaning component 10, which includes a housing 100 and a cleaning part 200.

[0053] Figure 2 for Figure 1 A cross-sectional schematic diagram of the cleaning mechanism provided in the document.

[0054] like Figure 2 As shown, the housing 100 is used to enclose and form a cleaning cavity 110. The cleaning component 200 is disposed in the cleaning cavity 110 and is connected to the housing 100. The cleaning component 200 is used to clean the area to be cleaned.

[0055] For example, the housing 100 can be fixedly mounted on the machine body. For instance, the housing 100 can be fixedly connected to the machine body by fasteners.

[0056] For example, the cleaning component 200 can be movably mounted on the housing 100. For instance, the cleaning component 200 can be mounted on the housing 100 via a drive component, which can be used to drive the cleaning component 200 to rotate or move relative to the housing 100 to clean the area to be cleaned.

[0057] For example, the cleaning component 200 can be a roller brush, or it can be any other brush that can move or rotate relative to the housing 100.

[0058] Figure 3 This is a schematic diagram of another cleaning mechanism provided in an embodiment of this application. In the figure, the direction pointed by the dashed arrow is the airflow direction between the cleaning chamber 110 and the collecting chamber 21 when the cleaning device is working.

[0059] In some possible embodiments, the cleaning mechanism further comprises a dust box 20, the dust box 20 is used to form a collecting cavity 21, the collecting cavity 21 is in communication with the cleaning cavity 110, and the collecting cavity 21 is used to collect dust and other dirt swept out by the sweeping component 200, so as to realize collection of the dust and other dirt swept out by the sweeping component 200.

[0060] For example, the dust and other dirt swept out by the sweeping component 200 can be moved into the collecting cavity 21 by the airflow flowing from the cleaning cavity 110 to the collecting cavity 21, and then collected by the dust box 20.

[0061] For example, the dust box 20 can be fixedly connected to the machine body by fasteners.

[0062] For example, the airflow flowing from the cleaning cavity 110 to the collecting cavity 21 can be generated when the sweeping component 200 sweeps, or the airflow flowing from the cleaning cavity 110 to the collecting cavity 21 can also be generated by the air pump 30 or other components.

[0063] In order to obtain the pollution degree of the area to be cleaned, so as to control the cleaning device according to the pollution degree of the area to be cleaned. In the embodiment of the present application, the sweeping assembly 10 further comprises a dust particle sensor 500, the dust particle sensor 500 is used to detect the concentration of suspended particulate matter at the position of the dust particle sensor 500, and the pollution degree of the area to be cleaned can be obtained according to the concentration of suspended particulate matter at the position of the dust particle sensor 500. In this way, the timeliness of obtaining the pollution degree of the area to be cleaned is better, and the cleaning device can be controlled in time. For example, the preferred cleaning mode can be started according to the pollution degree of the area to be cleaned.

[0064] In the related art, the dust particle sensor is often arranged on the shell, and the dust particle sensor is used to detect the concentration of suspended particulate matter in the cleaning cavity. However, in the related art, it is difficult to accurately obtain the dirt degree of the area to be cleaned by the dust particle sensor, so that it is difficult to accurately control the cleaning device according to the dirt degree of the area to be cleaned.

[0065] The inventors have found that, in the related art, it is difficult to accurately obtain the dirt degree of the area to be cleaned by the dust particle sensor, because the detection of the concentration of particulate matter by the dust particle sensor arranged on the shell is easily affected by the vibration (for example, vibration caused by relative movement of the sweeping component and the shell, vibration caused by collision of the sweeping component and the shell with obstacles, etc.) at the shell and the sweeping component, so that the dust particle sensor is difficult to accurately identify some particulate matter (for example, fine particulate matter such as carpet dust).

[0066] For example, in the related art, when the dust particle sensor is a piezoelectric dust particle sensor, the vibration noise at the cleaning component and the shell (e.g., vibration noise generated by relative movement of the cleaning component and the shell, vibration noise generated by collision of the cleaning component and the shell with an obstacle, etc.) will be received by the dust particle sensor, and the signal generated by the vibration noise at the cleaning component and the shell impacting the dust particle sensor is comparable to the signal generated by the impact of certain particles (e.g., carpet dust and other fine particles) on the dust particle sensor, so that even through signal amplification, it is difficult to distinguish the vibration noise at the cleaning component and the shell from certain particles (e.g., carpet dust and other fine particles), so that the dust particle sensor is more difficult to accurately identify certain particles (e.g., carpet dust and other fine particles). With the aging of the cleaning component and other components, the cleaning component and other components will gradually become hard, so that the vibration noise generated at the cleaning component and the shell will be more intense, and the impact on the detection of the dust particle sensor will be more pronounced.

[0067] As shown in Figures 1-3 Based on this, in the embodiments of the present application, the cleaning assembly 10 further comprises a first damping device 300 and an air duct structure 400, the air duct structure 400 is used to surround the air flow channel 410, one end of the air duct structure 400 is connected with the shell 100 through the first damping device 300, and the cleaning cavity 110 is communicated with the air flow channel 410 through the inner cavity of the first damping device 300. The dust particle sensor 500 is arranged on the air duct structure 400, and the dust particle sensor 500 is used to detect the concentration of suspended particles in the air flow channel 410.

[0068] In this way, the first damping device 300 can play a role in buffering and absorbing energy to attenuate the vibration and noise (for example, vibration and noise generated by the relative movement of the cleaning component 200 and the shell 100, vibration and noise generated by the collision of the cleaning component 200 and the shell 100 with an obstacle, etc.) transmitted from one side of the shell 100 to the airflow passage 410. The airflow passage 410 is in communication with the cleaning cavity 110, and the dust and other contaminants cleaned out by the cleaning component 200 can flow into the airflow passage 410 with the airflow. The dust particle sensor 500 is arranged on the air duct structure 400 and is used to detect the concentration of suspended particulate matter in the airflow passage 410. By arranging the first damping device 300 between the dust particle sensor 500 and the shell 100, the signal-to-noise ratio of the signal detected by the dust particle sensor 500 can be improved, so that while the dust particle sensor 500 can timely perceive the suspended particulate matter cleaned out by the cleaning component 200, the vibration and noise on one side of the shell 100 are less likely to affect the detection of the dust particle sensor 500, facilitating accurate identification of various particulate matter, and thus facilitating accurate and timely acquisition of the dirt level of the area to be cleaned, facilitating accurate and timely control of the cleaning equipment according to the dirt level of the area to be cleaned. In addition, after the signal-to-noise ratio of the signal detected by the dust particle sensor 500 is improved, the difficulty of subsequent processing of the signal detected by the dust particle sensor 500 can be reduced.

[0069] For example, the signal detected by the dust particle sensor 500 can be amplified, and the amplitude of the signal generated by the suspended particulate matter can be enhanced through signal amplification to eliminate the influence of the signal generated by the vibration and noise on the signal generated by the suspended particulate matter.

[0070] In some examples in which the cleaning mechanism includes the dust box 20, the air duct structure 400 is connected to the dust box 20 at an end away from the shell 100, and the cleaning cavity 110 is in communication with the collection cavity 21 through the airflow passage 410, so as to guide the dust and other contaminants cleaned out by the cleaning component 200 into the collection cavity 21 through the air duct structure 400.

[0071] In this way, the airflow passage 410 formed by the air duct structure 400 is used not only to detect the concentration of suspended particulate matter cleaned out by the cleaning component 200, but also to flow the contaminants cleaned out by the cleaning component 200 into the collection cavity 21, so that the cleaning equipment has fewer components and a simpler structure.

[0072] In some examples, the first damping device 300 can be connected to the air duct structure 400 and the shell 100 by bonding, clamping, fastening, or the like.

[0073] In some possible embodiments, the first damping device 300 is connected to the air duct structure 400 and the shell 100 by a joint.

[0074] In some possible embodiments, the first damping device 300 seals the gap between the one end of the air duct structure 400 connected to the shell 100 and the shell 100, so that the air duct structure 400 is connected to the shell 100 in a sealed manner by the first damping device 300.

[0075] In this way, the dirt such as dust cleaned by the cleaning component 200 is less likely to leak out at the first damping device 300, and the dirt cleaned by the cleaning component 200 is guided into the airflow passage 410, so that the accuracy of detecting the dirt level of the area to be cleaned is higher. In addition, the dirt cleaned by the cleaning component 200 is also facilitated to be collected by the collecting cavity 21.

[0076] For example, one end of the first damping device 300 is connected to the one end of the air duct structure 400 connected to the shell 100 in a sealed manner, and the other end of the first damping device 300 is connected to the shell 100 in a sealed manner.

[0077] For example, the first damping device 300 can be connected to the air duct structure 400 and the shell 100 in a sealed manner by a sealing glue, a sealing gasket or the like.

[0078] For example, the shell 100 has a first communication opening that communicates the cleaning cavity 110 with the outside of the shell 100, and the first damping device 300 is connected to the edge of the first communication opening and communicates with the cleaning cavity 110 through the first communication opening.

[0079] In some possible embodiments, the first damping device 300 includes a first damping member, the first damping member has a ring structure, one end of the first damping member is connected to one end of the air duct structure 400, the other end of the first damping member is connected to the shell 100, and the cleaning cavity 110 and the airflow passage 410 communicate through the inner cavity of the first damping member.

[0080] In this way, the first damping device 300 has a relatively simple structure, occupies a small space, and is convenient to assemble.

[0081] For example, the first damping member can be connected to the air duct structure 400 and the shell 100 by an adhesive manner.

[0082] Exemplarily, the first damping member can be a ring-shaped sleeve structure, and two ends of the first damping member can be sleeved on the joint portion of the air duct structure 400 and the joint portion of the housing 100 respectively and clamped with the joint portion of the air duct structure 400 and the joint portion of the housing 100 respectively, so as to realize the connection of the first damping member with the air duct structure 400 and the housing 100.

[0083] Exemplarily, the material of the first damping member can include but is not limited to damping materials such as silica gel, rubber, nylon and foam.

[0084] Exemplarily, the first damping member seals the gap between the one end of the air duct structure 400 connected with the housing 100 and the housing 100, so that the air duct structure 400 is sealingly connected with the housing 100 through the first damping member.

[0085] Exemplarily, the first damping member can be sealingly connected with the air duct structure 400 and the housing 100 through a sealing glue, a sealing member or the like, or can be sealingly connected with the air duct structure 400 and the housing 100 through the joint portion of the air duct structure 400 and the joint portion of the housing 100.

[0086] In other possible embodiments, the first damping device 300 can also be a hydraulic damper or an air pressure damper. The hydraulic damper can absorb and dissipate vibration energy by using the viscosity and fluid resistance of liquid. The air pressure damper can absorb and dissipate vibration energy by using the viscosity and fluid resistance of gas. At this time, the first damping device 300 has a flow channel that communicates the airflow channel 410 and the cleaning cavity 110.

[0087] In some possible embodiments, the dust particle sensor 500 is a piezoelectric dust particle sensor.

[0088] In this way, the concentration of the suspended particulate matter in the airflow channel 410 can be detected by sensing the vibration caused by the impact of the suspended particulate matter in the airflow channel 410. The piezoelectric dust particle sensor is sensitive to fine particulate matter, which is beneficial to realize detection under low concentration conditions. In addition, the structure of the piezoelectric dust particle sensor is relatively simple and the power consumption is relatively low, which is beneficial to arrangement in a cleaning device with a small size. In addition, the piezoelectric dust particle sensor can detect the concentration of the suspended particulate matter in the airflow channel by sensing the vibration caused by the impact of the suspended particulate matter on the air duct structure 400, so that the piezoelectric dust particle sensor can be arranged outside the air duct structure 400, and the arrangement of the dust particle sensor 500 is flexible.

[0089] The suspended particles in the airflow channel 410 are impacted against the channel wall of the airflow channel 410 under the driving of the airflow, and the vibration generated by the suspended particles impacting against the channel wall of the airflow channel 410 is acquired by the dust particle sensor 500 to form a vibration signal. The mass or particle size of the suspended particles can be sensed by detecting the amplitude of the vibration signal, and the mass density of the suspended particles can be sensed by detecting the integral area of the envelope curve formed by the vibration signal.

[0090] For example, the dust particle sensor 500 can be arranged on the upper side of the airflow channel 410.

[0091] In other possible embodiments, the dust particle sensor 500 can also be a capacitive dust particle sensor, a resistive dust particle sensor, an optical heat dissipation type dust particle sensor, etc.

[0092] In some examples in which the dust particle sensor 500 is a piezoelectric dust particle sensor, the dust particle sensor 500 is arranged on the outer side of the air duct structure 400 and attached to the surface of the air duct structure 400. The dust particle sensor 500 is used to detect the concentration of the suspended particles in the airflow channel 410 according to the vibration generated by the suspended particles in the airflow channel 410 impacting against the air duct structure 400.

[0093] In this way, the air tightness of the airflow channel 410 is maintained, so that dirt is not easily leaked at the dust particle sensor 500, and the dirt swept out by the cleaning component 200 is introduced into the collection cavity 21 for collection. In addition, it is not necessary to open an assembly port on the air duct structure 400 and block the assembly port, and the assembly of the dust particle sensor 500 is easier.

[0094] In other examples, the air duct structure 400 has an assembly port that communicates the airflow channel 410 with the outer side of the air duct structure 400, the dust particle sensor 500 is arranged in the assembly port, and the dust particle sensor 500 is sealingly connected with the air duct structure 400 at the assembly port to block the assembly port. At this time, the dust particle sensor 500 forms part of the channel wall of the airflow channel 410.

[0095] In this way, the dust particle sensor 500 and the suspended particles to be detected are located in one chamber, and the selection of the dust particle sensor 500 is less restricted. In addition, the dust particle sensor 500 and the suspended particles to be detected are located in one chamber, which also helps to improve the detection accuracy and efficiency of the concentration of the suspended particles.

[0096] In some possible embodiments, the cleaning mechanism can further include a second damping device 600, which is arranged between the dust box 20 and the end of the air duct structure 400 away from the housing 100, and the end of the air duct structure 400 away from the housing 100 is connected to the dust box 20 through the second damping device 600, and the airflow passage 410 is in communication with the collection cavity 21 of the dust box 20 through the inner cavity of the second damping device 600.

[0097] In this way, the second damping device 600 can play a role of buffering and absorbing energy to attenuate the vibration and noise transmitted from the side of the dust box 20 to the airflow passage 410, and can improve the signal-to-noise ratio of the signal detected by the dust particle sensor 500, so that the vibration and noise of the side of the dust box 20 are less likely to affect the detection of the dust particle sensor 500, and accurate identification of various particulate matters can be facilitated, and then the degree of dirtiness of the area to be cleaned can be accurately and timely obtained, and the cleaning equipment can be accurately and timely controlled according to the degree of dirtiness of the area to be cleaned. In addition, after the signal-to-noise ratio of the signal detected by the dust particle sensor 500 is improved, the difficulty of subsequent processing of the signal detected by the dust particle sensor 500 can be reduced.

[0098] In some examples, the second damping device 600 can be connected to the air duct structure 400 and the dust box 20 by bonding, clamping, fastener connection or the like.

[0099] In other examples, the air duct structure 400 and the dust box 20 can each have a joint portion for connecting the second damping device 600, and the two ends of the second damping device 600 can be respectively sleeved on the joint portions of the air duct structure 400 and the dust box 20 and clamped with the joint portions of the air duct structure 400 and the dust box 20 to realize the connection of the second damping device 600 with the air duct structure 400 and the dust box 20.

[0100] In some examples, the cleaning assembly 10 can include the second damping device 600, that is, the second damping device 600 can be part of the cleaning assembly 10.

[0101] In other examples, the second damping device 600 can also be a component independent of the cleaning assembly 10.

[0102] In some possible embodiments, the second damping device 600 is sealingly connected to the end of the air duct structure 400 away from the housing 100.

[0103] In this way, the second damping device 600 can be used to sealingly connect the air duct structure 400 and the dust box 20.

[0104] In some possible implementation manners, the second damping device 600 seals the gap between the one end of the air duct structure 400 away from the shell 100 and the dust box 20, so that the air duct structure 400 is sealingly connected to the dust box 20 through the second damping device 600.

[0105] In this way, the dirt such as dust swept by the cleaning component 200 is less likely to leak out at the second damping device 600, and the dirt swept by the cleaning component 200 is further guided into the collection cavity 21 for collection.

[0106] For example, one end of the second damping device 600 is sealingly connected to the one end of the air duct structure 400 away from the shell 100, and the other end of the second damping device 600 is sealingly connected to the dust box 20.

[0107] For example, the second damping device 600 can be sealingly connected to the air duct structure 400 and the dust box 20 through a sealing glue, a sealing gasket or the like.

[0108] For example, the dust box 20 has a second communication opening that communicates the collection cavity 21 with the outside of the dust box 20, and the second damping device 600 is connected to the edge of the second communication opening and communicates with the collection cavity 21 through the second communication opening.

[0109] In some possible implementation manners, the second damping device 600 includes a second damping member, the second damping member has a ring structure, one end of the second damping member is connected to the one end of the air duct structure 400 away from the shell 100, the other end of the second damping member is connected to the dust box 20, and the airflow passage 410 communicates with the collection cavity 21 through the inner cavity of the second damping member.

[0110] In this way, the second damping device 600 has a relatively simple structure, occupies a relatively small space, and is relatively convenient to assemble.

[0111] For example, the second damping member can be connected to the air duct structure 400 and the dust box 20 through bonding.

[0112] For example, the second damping member can have a ring-shaped sleeve structure, and the two ends of the second damping member can be respectively sleeved on the joint portions of the air duct structure 400 and the dust box 20 and clamped to the joint portions of the air duct structure 400 and the dust box 20, so as to realize the connection of the second damping member to the air duct structure 400 and the dust box 20.

[0113] For example, the material of the second damping member can include, but is not limited to, a damping material such as silica gel, rubber, nylon, foam or the like.

[0114] For example, the second damping member seals the gap between the one end of the air duct structure 400 away from the shell 100 and the dust box 20, so that the air duct structure 400 is sealingly connected to the dust box 20 through the second damping member.

[0115] For example, the second damping member can be sealedly connected with the air duct structure 400 and the dust box 20 by a sealant, a seal, or the like, or can be sealedly connected with the air duct structure 400 and the dust box 20 by being attached to the joint portion of the air duct structure 400 and the joint portion of the dust box 20.

[0116] In some possible embodiments, the second damping device 600 can also be a hydraulic damper or an air pressure damper. In this case, the second damping device 600 has a flow channel that communicates with the air flow channel 410 and the collection cavity 21.

[0117] In some possible embodiments, the cleaning mechanism further includes an air pump 30. The air suction end of the air pump 30 is connected with the dust box 20, the air suction end of the air pump 30 communicates with the collection cavity 21, and the air pump 30 is configured to drive the air flow in the air flow channel 410 to flow to the collection cavity 21.

[0118] In this way, the dirt such as dust swept out by the sweeping component 200 can be sucked into the collection cavity 21 by the air pump 30, so that the dirt such as dust swept out by the sweeping component 200 is more easily moved to the collection cavity 21.

[0119] By driving of the air pump 30, the air flow generated by the sweeping cavity 110 along the air flow channel 410 and the collection cavity 21 to the air pump 30, and thus the dirt such as dust swept out by the sweeping component 200 can be driven to move from the sweeping cavity 110 to the collection cavity 21.

[0120] When the cleaning mechanism includes the second damping device 600, the second damping device 600 can attenuate the vibration and noise generated by the air pump 30, and the air pump 30 has less influence on the detection of the dust particle sensor 500, so that the dust particle sensor 500 can accurately detect the concentration of the suspended particulate matter in the air flow channel 310 while the dirt such as dust swept out by the sweeping component 200 is sucked into the collection cavity 21 by the air pump 30, so that the degree of dirtiness of the area to be cleaned can be timely and accurately obtained.

[0121] In some examples, the air pump 30 can be fixedly connected with the dust box 20 by the support 40.
