Description

Cleaning components, cleaning mechanisms and cleaning equipment

[0001] This application claims priority to Chinese Patent Application No. 202520042585.7, filed on January 8, 2025, entitled "Cleaning Components, Cleaning Mechanism and Cleaning Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment technology, and in particular to a cleaning component, cleaning mechanism and cleaning equipment. Background Technology

[0003] Cleaning equipment such as robot vacuums and vacuum cleaners may include a cleaning mechanism, through which the cleaning equipment performs its cleaning function.

[0004] In related technologies, cleaning mechanisms may include sweeping components used to clean the area to be cleaned. However, in these technologies, it is difficult for cleaning equipment to accurately determine the degree of dirt in the area to be cleaned, making it difficult to accurately control the cleaning equipment based on the degree of dirt.

[0005] Therefore, how to accurately determine the degree of dirtiness in the area to be cleaned has become an urgent problem to be solved in the field of cleaning equipment technology.

[0006] Utility Model Content

[0007] This application provides a cleaning component, a cleaning mechanism, and a cleaning device to solve the problem in the related art that cleaning devices have difficulty accurately obtaining the degree of dirt in the area to be cleaned.

[0008] A first aspect of this application provides a cleaning assembly, which includes a housing, a cleaning component, a first damping device, an air duct structure, and a dust particle sensor. The housing encloses a cleaning chamber, and the cleaning component is disposed within the cleaning chamber. The air duct structure encloses an airflow channel, one end of which is connected to the housing via the first damping device. The cleaning chamber and the airflow channel are connected through the inner cavity of the first damping device. The dust particle sensor is disposed on the air duct structure and is used to detect the concentration of suspended particulate matter within the airflow channel.

[0009] The cleaning assembly provided in this application embodiment has a first damping device that acts as a buffer to absorb energy, thereby attenuating vibrations and noise transmitted from one side of the housing into the airflow channel. By using the first damping device between the dust particle sensor and the housing, the signal-to-noise ratio of the signal detected by the dust particle sensor mounted on the airflow duct structure can be improved. This allows the dust particle sensor to promptly detect suspended particles swept up by the cleaning component, while vibrations and noise from one side of the housing are less likely to affect the sensor's detection. This facilitates accurate identification of various particles, enabling accurate and timely acquisition of the degree of dirt in the area to be cleaned. This, in turn, allows for accurate and timely control of the cleaning equipment based on the degree of dirt in the area. Furthermore, the improved signal-to-noise ratio of the signal detected by the dust particle sensor reduces the difficulty of subsequent signal processing.

[0010] In one possible implementation, the first damping device seals the gap between one end of the duct structure component connecting to the housing and the housing, so that the duct structure component is sealed to the housing through the first damping device.

[0011] In this way, dust and other dirt swept up by the cleaning components are less likely to leak out at the first damping device, making it easier to guide the dirt swept up by the cleaning components into the airflow channel, thus improving the accuracy of detecting the degree of dirt in the area to be cleaned. In addition, it also facilitates the collection of dirt swept up by the cleaning components.

[0012] In one possible implementation, the first damping device includes a first damping element, which is a ring structure. One end of the first damping element is connected to one end of the air duct structure, and the other end of the first damping element is connected to the housing. The cleaning chamber and the airflow channel are connected through the inner cavity of the first damping element.

[0013] Thus, the first damping device has a relatively simple structure, occupies less space, and is relatively easy to assemble.

[0014] In one possible implementation, the dust particle sensor is a piezoelectric dust particle sensor.

[0015] Thus, the concentration of suspended particles in the airflow channel can be detected by sensing the vibrations generated by the impact of suspended particles. Piezoelectric dust particle sensors are highly sensitive to fine particles, making them suitable for detection under low-concentration conditions. Furthermore, the piezoelectric dust particle sensor has a simple structure and low power consumption, facilitating its placement in smaller cleaning equipment. Additionally, the piezoelectric dust particle sensor can detect the concentration of suspended particles in the airflow channel by sensing the vibrations generated by the impact of suspended particles on the duct structure, allowing it to be placed outside the duct structure, providing greater flexibility in placement.

[0016] In one possible implementation, the dust particle sensor is located on the outside of the duct structure and attached to its surface. The dust particle sensor is used to detect the concentration of suspended particles in the airflow channel based on the vibrations generated by the impact of suspended particles against the duct structure.

[0017] This helps maintain the airtightness of the airflow channel, preventing dirt from easily leaking out at the dust particle sensor, and thus facilitating the collection of dirt swept out by the cleaning components into the collection chamber. Furthermore, there is no need to open or seal the mounting opening on the air duct structure, making the assembly of the dust particle sensor easier.

[0018] In one possible implementation, the cleaning assembly further includes a second damping device located at the end of the air duct structure away from the housing. The end of the air duct structure away from the housing is used to connect to the dust box of the cleaning mechanism via the second damping device. The airflow channel is used to communicate with the collection cavity formed by the dust box through the inner cavity of the second damping device.

[0019] Thus, the second damping device can buffer and absorb energy, attenuating vibrations and noise transmitted from the dust box side into the airflow channel. This improves the signal-to-noise ratio of the signal detected by the dust particle sensor, making it less susceptible to interference from vibrations and noise on the dust box side. This facilitates accurate identification of various particles, enabling accurate and timely assessment of the degree of dirt in the area to be cleaned. This, in turn, allows for accurate and timely control of the cleaning equipment based on the level of dirt in the area. Furthermore, the improved signal-to-noise ratio of the signal detected by the dust particle sensor reduces the difficulty of subsequent signal processing.

[0020] In one possible implementation, the second damping device includes a second damping element, which is a ring structure. One end of the second damping element is connected to the end of the air duct structure that is away from the housing. The other end of the first damping element is used to connect to the dust box. The airflow channel is used to communicate with the collection chamber through the inner cavity of the second damping element.

[0021] Thus, the second damping device has a relatively simple structure, occupies less space, and is relatively easy to assemble.

[0022] In one possible implementation, the second damping device is sealed to the end of the duct structure away from the housing.

[0023] This facilitates a sealed connection between the duct structure and the dust box via the second damping device.

[0024] A second aspect of this application provides a cleaning mechanism, which includes a dust box and a cleaning assembly as described in any of the above embodiments. The dust box is used to enclose and form a collection cavity. The end of the air duct structure of the cleaning assembly away from the housing of the cleaning assembly is connected to the dust box. The cleaning cavity formed by the housing is connected to the collection cavity through an airflow channel formed by the air duct structure.

[0025] Thus, the airflow channel formed by the duct structure not only detects the concentration of suspended particles swept up by the cleaning components, but also allows the waste swept up by the cleaning components to flow into the collection chamber, facilitating the collection of dust and other dirt swept up by the cleaning components. Furthermore, this results in fewer components and a simpler structure for the cleaning equipment.

[0026] In one possible implementation, the second damping device of the cleaning component is located between the end of the air duct structure away from the housing and the dust box. The end of the air duct structure away from the housing is connected to the dust box through the second damping device, and the airflow channel and the collection chamber are connected through the inner cavity of the second damping device.

[0027] In one possible implementation, the second damping device seals the gap between the end of the duct structure away from the housing and the dust box, so that the duct structure is sealed to the dust box through the second damping device.

[0028] In this way, the dust and dirt swept out by the cleaning components are less likely to leak out at the second damping device, which in turn facilitates the collection of the dirt swept out by the cleaning components into the collection chamber.

[0029] In one possible implementation, the cleaning mechanism also includes an air pump. The air pump's suction end is connected to the dust box and communicates with the collection chamber. The air pump is used to drive the airflow in the airflow channel toward the collection chamber.

[0030] In this way, the air pump can suck the dust and other dirt swept up by the cleaning components into the collection chamber, making it easier for the dust and other dirt swept up by the cleaning components to move into the collection chamber.

[0031] When the cleaning mechanism includes a second damping device, the second damping device can attenuate the vibration and noise generated by the air pump. The air pump has a smaller impact on the detection of the dust particle sensor. This allows the dust and other dirt swept up by the cleaning components to be sucked into the collection chamber by the air pump, while the dust particle sensor can accurately detect the concentration of suspended particles in the airflow channel, so as to obtain the degree of dirt in the area to be cleaned in a timely and accurate manner.

[0032] In one possible implementation, the cleaning mechanism further includes a third damping device. The third damping device is located between the suction end of the air pump and the dust box, with the suction end of the air pump connected to the dust box via the third damping device, and the suction end of the air pump communicating with the collection chamber through the inner cavity of the third damping device.

[0033] Thus, the third damping device can act as a buffer to absorb energy, attenuating vibrations and noise transmitted from the air pump side into the airflow channel. This improves the signal-to-noise ratio of the signal detected by the dust particle sensor, making it less susceptible to interference from vibrations and noise on the air pump side. This facilitates accurate identification of various particles, enabling accurate and timely assessment of the degree of dirt in the area to be cleaned. This, in turn, allows for accurate and timely control of the cleaning equipment based on the level of dirt in the area. Furthermore, the improved signal-to-noise ratio of the signal detected by the dust particle sensor reduces the difficulty of subsequent signal processing.

[0034] A third aspect of this application provides a cleaning device, which includes a body and a cleaning mechanism as described in any of the above embodiments, the cleaning mechanism being disposed on the body. Attached Figure Description

Detailed Implementation

[0041] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] In other examples, the body can also be a body that can be moved manually by the user.

[0046] Figure 1 is a schematic diagram of a cleaning mechanism provided in an embodiment of this application.

[0047] As shown in Figure 1, in this embodiment of the application, the cleaning mechanism includes a cleaning component 10, which includes a housing 100 and a cleaning part 200.

[0048] Figure 2 is a cross-sectional schematic diagram of the cleaning mechanism shown in Figure 1.

[0049] As shown in Figure 2, 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Figure 3 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.

[0054] In some possible implementations, the cleaning mechanism also includes a dust box 20, which is used to enclose a collection chamber 21. The collection chamber 21 is connected to the cleaning chamber 110 and is used to collect dust and other dirt swept out by the cleaning component 200, so as to facilitate the collection of dust and other dirt swept out by the cleaning component 200.

[0055] For example, dust and other dirt swept up by the cleaning component 200 can be moved into the collection chamber 21 by the airflow flowing from the cleaning chamber 110 to the collection chamber 21, and collected by the dust box 20.

[0056] For example, the dustbin 20 can be fixedly mounted on the body. For instance, the dustbin 20 can be fixedly connected to the body using fasteners.

[0057] For example, the airflow flowing from the cleaning chamber 110 to the collection chamber 21 can be generated by the cleaning component 200 during cleaning, or the airflow flowing from the cleaning chamber 110 to the collection chamber 21 can also be generated by a component such as the air pump 30.

[0058] To obtain the degree of contamination in the area to be cleaned, and thus control the cleaning equipment accordingly, the cleaning assembly 10 in this embodiment further includes a dust particle sensor 500. The dust particle sensor 500 detects the concentration of suspended particulate matter at its location, and the degree of contamination in the area to be cleaned can be determined based on this concentration. This provides better timeliness in obtaining the degree of contamination, facilitating timely control of the cleaning equipment. For example, a preferred cleaning mode can be activated based on the degree of contamination in the area.

[0059] In related technologies, dust particle sensors are often mounted on the housing and are used to detect the concentration of suspended particles within the cleaning chamber. However, in these technologies, it is difficult to accurately determine the degree of dirtiness in the area to be cleaned using dust particle sensors, making it challenging to accurately control the cleaning equipment based on the level of dirtiness.

[0060] The inventors discovered that in related technologies, it is difficult to accurately obtain the degree of dirtiness of the area to be cleaned using a dust particle sensor. This is because the dust particle sensor, which is mounted on the housing, is easily affected by vibrations at the housing and cleaning components (e.g., vibrations caused by the relative movement of the cleaning components and the housing, vibrations caused by the collision of the cleaning components and the housing with obstacles). This makes it difficult for the dust particle sensor to accurately identify certain particles (e.g., fine particles such as carpet dust).

[0061] For example, in related technologies, when the dust particle sensor is a piezoelectric dust particle sensor, vibration noise from the cleaning component and housing (e.g., vibration noise generated by the relative motion between the cleaning component and housing, vibration noise generated by the cleaning component and housing colliding with obstacles, etc.) will be received by the dust particle sensor. The signal generated by the vibration noise from the cleaning component and housing impacting the dust particle sensor is on the same order of magnitude as the signal generated by certain particles (e.g., fine particles such as carpet dust) impacting the dust particle sensor. This makes it difficult to distinguish between the vibration noise from the cleaning component and housing and certain particles (e.g., fine particles such as carpet dust) even with signal amplification, making it difficult for the dust particle sensor to accurately identify certain particles (e.g., fine particles such as carpet dust). As the cleaning component and other components age, they gradually harden, making the vibration noise generated between the cleaning component and housing more intense and its impact on the detection of the dust particle sensor more prominent.

[0062] As shown in Figures 1-3, based on this, in this embodiment of the application, the cleaning assembly 10 further includes a first damping device 300 and an air duct structure 400. The air duct structure 400 is used to enclose and form an airflow channel 410. One end of the air duct structure 400 is connected to the housing 100 through the first damping device 300, and the cleaning chamber 110 and the airflow channel 410 are connected through the inner cavity of the first damping device 300. A dust particle sensor 500 is disposed on the air duct structure 400, and the dust particle sensor 500 is used to detect the concentration of suspended particulate matter in the airflow channel 410.

[0063] In this way, the first damping device 300 can act as a buffer to absorb energy, thereby attenuating the vibrations and noises transmitted from one side of the housing 100 to the airflow channel 410 (e.g., vibrations and noises generated by the relative movement of the cleaning component 200 and the housing 100, vibrations and noises generated by the collision of the cleaning component 200 and the housing 100 with obstacles, etc.). The airflow channel 410 is connected to the cleaning chamber 110. Dust and other dirt swept up by the cleaning component 200 can flow into the airflow channel 410 with the airflow. The dust particle sensor 500 is installed on the air duct structure 400 and is used to detect the concentration of suspended particles in the airflow channel 410. Through the first damping device 300 installed between the dust particle sensor 500 and the housing 100, the signal-to-noise ratio of the signal detected by the dust particle sensor 500 can be improved. This allows the dust particle sensor 500 to detect the suspended particles swept up by the cleaning component 200 in a timely manner, while the vibration and noise on one side of the housing 100 are less likely to affect the detection of the dust particle sensor 500. This facilitates the accurate identification of various particles, and thus facilitates the accurate and timely acquisition of the degree of dirt in the area to be cleaned. This allows for accurate and timely control of the cleaning equipment based on the degree of dirt in the area to be cleaned. In addition, the improved signal-to-noise ratio of the signal detected by the dust particle sensor 500 reduces the difficulty of subsequent processing of the signal detected by the dust particle sensor 500.

[0064] For example, the signal detected by the dust particle sensor 500 can be amplified to enhance the amplitude of the signal generated by suspended particles, thereby eliminating the influence of vibration and noise on the signal generated by suspended particles.

[0065] In some examples of cleaning mechanisms including dust box 20, the end of air duct structure 400 away from housing 100 is connected to dust box 20, and cleaning chamber 110 is connected to collection chamber 21 through airflow channel 410 so that dust and other dirt swept by cleaning component 200 can be introduced into collection chamber 21 through air duct structure 400.

[0066] In this way, the airflow channel 410 formed by the air duct structure 400 is used not only to detect the concentration of suspended particulate matter swept out by the cleaning component 200, but also to allow the waste swept out by the cleaning component 200 to flow into the collection chamber 21, which can reduce the number of parts and simplify the structure of the cleaning equipment.

[0067] In some examples, the first damping device 300 can be connected to the duct structure 400 and the housing 100 by means of bonding, snap-fitting, fastener connection, etc.

[0068] In other examples, the duct structure 400 and the housing 100 may each have a connector for connecting the first damping device 300. The two ends of the first damping device 300 may be respectively sleeved on the connector of the duct structure 400 and the connector of the housing 100, and respectively clamped to the connector of the duct structure 400 and the connector of the housing 100, so as to realize the connection between the first damping device 300 and the duct structure 400 and the housing 100.

[0069] In some possible implementations, the first damping device 300 seals the gap between one end of the air duct structure 400 connecting to the housing 100 and the housing 100, so that the air duct structure 400 is sealed to the housing 100 through the first damping device 300.

[0070] In this way, dust and other dirt swept up by the cleaning component 200 are less likely to leak out at the first damping device 300, making it easier to guide the dirt swept up by the cleaning component 200 into the airflow channel 410, thus improving the accuracy of detecting the degree of dirt in the area to be cleaned. In addition, it also facilitates the collection of dirt swept up by the cleaning component 200 in the collection chamber 21.

[0071] For example, one end of the first damping device 300 is sealed to one end of the housing 100 of the air duct structure 400, and the other end of the first damping device 300 is sealed to the housing 100.

[0072] For example, the first damping device 300 can be sealed to the duct structure 400 and the housing 100 by means of sealant, gasket, etc.

[0073] For example, the housing 100 has a first communication port connecting the cleaning chamber 110 and the outside of the housing 100, and the first damping device 300 is connected to the edge of the first communication port and communicates with the cleaning chamber 110 through the first communication port.

[0074] In some possible implementations, the first damping device 300 includes a first damping element, which is a ring structure. One end of the first damping element is connected to one end of the air duct structure 400, and the other end of the first damping element is connected to the housing 100. The cleaning chamber 110 and the airflow channel 410 are connected through the inner cavity of the first damping element.

[0075] Thus, the first damping device 300 has a relatively simple structure, occupies less space, and is relatively easy to assemble.

[0076] For example, the first damping element can be connected to the duct structure 400 and the housing 100 by adhesive bonding.

[0077] For example, the first damping member can be a ring-shaped sleeve structure. The two ends of the first damping member can be respectively sleeved on the joint of the air duct structure 400 and the joint of the housing 100, and clamped to the joint of the air duct structure 400 and the joint of the housing 100, so as to realize the connection between the first damping member and the air duct structure 400 and the housing 100.

[0078] For example, the material of the first damping element may include, but is not limited to, damping materials such as silicone, rubber, nylon, and foam.

[0079] For example, the first damping element seals the gap between one end of the air duct structure 400 and the housing 100, so that the air duct structure 400 is sealed to the housing 100 through the first damping element.

[0080] For example, the first damping element can be sealed to the duct structure 400 and the housing 100 by means of sealant, sealant, etc., or it can be sealed to the duct structure 400 and the housing 100 by fitting with the joint of the duct structure 400 and the joint of the housing 100.

[0081] In some other possible embodiments, the first damping device 300 may also be a hydraulic damper or a pneumatic damper. A hydraulic damper utilizes the viscosity and fluid resistance of a liquid to absorb and dissipate vibrational energy. A pneumatic damper utilizes the viscosity and fluid resistance of a gas to absorb and dissipate vibrational energy. In this case, the first damping device 300 has a flow channel connecting the airflow passage 410 and the cleaning chamber 110.

[0082] In some possible implementations, the dust particle sensor 500 is a piezoelectric dust particle sensor.

[0083] In this way, the concentration of suspended particles within the airflow channel 410 can be detected by sensing the vibrations generated by the impact of suspended particles within the channel. The piezoelectric dust particle sensor is highly sensitive to fine particles, facilitating detection under low-concentration conditions. Furthermore, the piezoelectric dust particle sensor has a simple structure and low power consumption, making it suitable for placement in smaller cleaning equipment. Additionally, the piezoelectric dust particle sensor can detect the concentration of suspended particles within the airflow duct by sensing the vibrations generated by the impact of suspended particles against the duct structure 400, allowing the sensor to be placed outside the duct structure 400, thus providing greater flexibility in placement.

[0084] The suspended particles in the airflow channel 410 vibrate when they collide with the channel wall of the airflow channel 410 under the influence of the airflow. The vibration generated by the suspended particles colliding with the channel wall of the airflow channel 410 is acquired by the dust particle sensor 500 and forms 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.

[0085] For example, the dust particle sensor 500 may be disposed on the upper side of the airflow channel 410.

[0086] In other possible implementations, the dust particle sensor 500 may also be a capacitive dust particle sensor, a resistive dust particle sensor, an optical heat dissipation type dust particle sensor, etc.

[0087] In some examples where the dust particle sensor 500 is a piezoelectric dust particle sensor, the dust particle sensor 500 is located on the outside 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 suspended particles in the air duct 410 based on the vibration generated by suspended particles in the air duct structure 400 impacting the air duct structure 400.

[0088] This helps maintain the airtightness of the airflow channel 410, making it less likely for dirt to leak out at the dust particle sensor 500, and thus facilitating the collection of dirt swept out by the cleaning component 200 into the collection chamber 21. In addition, there is no need to open and seal the mounting port on the air duct structure component 400, making the assembly of the dust particle sensor 500 easier.

[0089] In other examples, the duct structure 400 has an assembly port connecting the airflow channel 410 and the outside of the duct structure 400. A dust particle sensor 500 is inserted into the assembly port, and the dust particle sensor is sealed to the duct structure 400 at the assembly port to block the assembly port. In this case, the dust particle sensor forms part of the channel wall of the airflow channel 410.

[0090] In this way, the dust particle sensor 500 and the suspended particles to be detected are located in the same chamber, which reduces the limitations on the selection of the dust particle sensor 500. In addition, the fact that the dust particle sensor 500 and the suspended particles to be detected are located in the same chamber also helps to improve the detection accuracy and efficiency of the suspended particle concentration.

[0091] In some possible implementations, the cleaning mechanism may also include a second damping device 600, which is located between the end of the air duct structure 400 away from the housing 100 and the dust box 20. 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. The airflow channel 410 is connected to the collection cavity 21 formed by the dust box 20 through the inner cavity of the second damping device 600.

[0092] In this way, the second damping device 600 can buffer and absorb energy, attenuating the vibration and noise transmitted from the dust box 20 side to the airflow channel 410. This improves the signal-to-noise ratio of the signal detected by the dust particle sensor 500, making it less likely for vibration and noise from the dust box 20 side to affect the detection of the dust particle sensor 500. This facilitates accurate identification of various particles, and consequently, accurate and timely acquisition of the degree of dirt in the area to be cleaned. It also allows for accurate and timely control of the cleaning equipment based on the degree of dirt in the area to be cleaned. Furthermore, the improved signal-to-noise ratio of the signal detected by the dust particle sensor 500 reduces the difficulty of subsequent processing of the signal detected by the dust particle sensor 500.

[0093] In some examples, the second damping device 600 can be connected to the duct structure 400 and the dust box 20 by means of bonding, snap-fitting, fastening, etc.

[0094] In other examples, the duct structure 400 and the dust box 20 may each have a connector for connecting the second damping device 600. The two ends of the second damping device 600 may be respectively sleeved on the connector of the duct structure 400 and the connector of the dust box 20, and clamped to the connector of the duct structure 400 and the connector of the dust box 20, so as to realize the connection between the second damping device 600 and the duct structure 400 and the dust box 20.

[0095] In some examples, the cleaning assembly 10 may include a second damping device 600, that is, the second damping device 600 may be part of the cleaning assembly 10.

[0096] In other examples, the second damping device 600 may also be a component independent of the cleaning assembly 10.

[0097] In some possible implementations, the second damping device 600 is sealed to the end of the duct structure 400 away from the housing 100.

[0098] This facilitates the sealing connection between the air duct structure 400 and the dust box 20 via the second damping device 600.

[0099] In some possible implementations, the second damping device 600 seals the gap between the end of the duct structure 400 away from the housing 100 and the dust box 20, so that the duct structure 400 is sealed to the dust box 20 through the second damping device 600.

[0100] In this way, the dust and dirt swept out by the cleaning component 200 are less likely to leak out at the second damping device 600, which facilitates the collection of the dirt swept out by the cleaning component 200 into the collection chamber 21 for collection.

[0101] For example, one end of the second damping device 600 is sealed to the end of the air duct structure 400 away from the housing 100, and the other end of the second damping device 600 is sealed to the dust box 20.

[0102] For example, the second damping device 600 can be sealed to the duct structure 400 and the dust box 20 by means of sealant, gasket, etc.

[0103] For example, the dust box 20 has a second communication port connecting the collection chamber 21 and the outside of the dust box 20, and the second damping device 600 is connected to the edge of the second communication port and communicates with the collection chamber 21 through the second communication port.

[0104] In some possible implementations, the second damping device 600 includes a second damping element, which is a ring structure. One end of the second damping element is connected to the end of the air duct structure 400 away from the housing 100, and the other end of the first damping element is connected to the dust box 20. The airflow channel 410 communicates with the collection chamber 21 through the inner cavity of the second damping element.

[0105] Thus, the second damping device 600 has a relatively simple structure, occupies less space, and is relatively easy to assemble.

[0106] For example, the second damping element can be connected to the duct structure 400 and the dust box 20 by adhesive bonding.

[0107] For example, the second damping member can be a ring-shaped sleeve structure. The two ends of the second damping member can be respectively sleeved on the joint of the air duct structure 400 and the joint of the dust box 20, and clamped to the joint of the air duct structure 400 and the joint of the dust box 20, so as to realize the connection between the second damping member and the air duct structure 400 and the dust box 20.

[0108] For example, the material of the second damping element may include, but is not limited to, damping materials such as silicone, rubber, nylon, and foam.

[0109] For example, the second damping element seals the gap between the end of the air duct structure 400 away from the housing 100 and the dust box 20, so that the air duct structure 400 is sealed to the dust box 20 through the second damping element.

[0110] For example, the second damping element can be sealed to the duct structure 400 and the dust box 20 by means of sealant, sealant, etc., or it can be sealed to the duct structure 400 and the dust box 20 by fitting with the joint of the duct structure 400 and the joint of the dust box 20.

[0111] In some other possible embodiments, the second damping device 600 may also be a hydraulic damper or a pneumatic damper. In this case, the second damping device 600 has a flow channel connecting the airflow passage 410 and the collection chamber 21.

[0112] In some possible implementations, the cleaning mechanism also includes an air pump 30. The suction end of the air pump 30 is connected to the dust box 20 and communicates with the collection chamber 21. The air pump 30 is used to drive the airflow in the airflow channel 410 to flow into the collection chamber 21.

[0113] In this way, the air pump 30 can suck the dust and other dirt swept up by the cleaning component 200 into the collection chamber 21, making it easier for the dust and other dirt swept up by the cleaning component 200 to move into the collection chamber 21.

[0114] Driven by the air pump 30, an airflow is generated from the cleaning chamber 110 along the airflow channel 410 and the collection chamber 21 to the air pump 30, which in turn drives the dust and other dirt swept out by the cleaning component 200 to move from the cleaning chamber 110 to the collection chamber 21.

[0115] When the cleaning mechanism includes a second damping device 600, the second damping device 600 can attenuate the vibration and noise generated by the air pump 30. The air pump 30 has a smaller impact on the detection of the dust particle sensor 500. This allows the dust and other dirt swept up by the cleaning component 200 to be sucked into the collection chamber 21 by the air pump 30, while the dust particle sensor 500 can accurately detect the concentration of suspended particles in the airflow channel 310, so as to obtain the degree of dirt in the area to be cleaned in a timely and accurate manner.

[0116] In some examples, the air pump 30 can be fixedly connected to the dust box 20 via the bracket 40.

[0117] Figure 4 is a schematic diagram of another cleaning mechanism provided in an embodiment of this application.

[0118] In some possible implementations, the cleaning mechanism further includes a third damping device 50. The third damping device 50 is disposed between the suction end of the air pump 30 and the dust box 20. The suction end of the air pump 30 is connected to the dust box 20 through the third damping device 50, and the suction end of the air pump 30 is connected to the collection chamber 21 through the inner cavity of the third damping device 50.

[0119] In this way, the third damping device 50 can act as a buffer to absorb energy, attenuating the vibration and noise transmitted from the air pump 30 side to the airflow channel 410. This improves the signal-to-noise ratio of the signal detected by the dust particle sensor 500, making it less likely for vibration and noise from the air pump 30 side to affect the detection of the dust particle sensor 500. This facilitates accurate identification of various particles, and consequently, accurate and timely acquisition of the degree of dirt in the area to be cleaned. It also allows for accurate and timely control of the cleaning equipment based on the degree of dirt in the area to be cleaned. Furthermore, the improved signal-to-noise ratio of the signal detected by the dust particle sensor 500 reduces the difficulty of subsequent processing of the signal detected by the dust particle sensor 500.

[0120] In some examples, the third damping device 50 can be connected to the air pump 30 and the dust box 20 by means of bonding, snap-fitting, fastening, etc.

[0121] In other examples, the air pump 30 and the dust box 20 may each have a connector for connecting the third damping device 50. The two ends of the third damping device 50 may be respectively sleeved on the connector of the air pump 30 and the connector of the dust box 20, and clamped to the connector of the air pump 30 and the connector of the dust box 20, so as to realize the connection between the third damping device 50 and the air pump 30 and the dust box 20.

[0122] In some possible implementations, the third damping device 50 seals the gap between the suction end of the air pump 30 and the dust box 20, so that the suction end of the air pump 30 is sealed to the dust box 20 through the third damping device 50.

[0123] This facilitates the air pump 30 to draw out the gas in the collection chamber 21, so that the dust and other dirt swept up by the cleaning component 200 can be sucked into the collection chamber 21.

[0124] For example, one end of the third damping device 50 is sealed to the suction end of the air pump 30, and the other end of the third damping device 50 is sealed to the dust box 20.

[0125] For example, the third damping device 50 can be sealed to the suction end of the air pump 30 and the dust box 20 by means of sealant, gasket, etc.

[0126] For example, the dust box 20 has a third communication port connecting the collection chamber 21 and the outside of the dust box 20, and the third damping device 50 is connected to the edge of the third communication port and communicates with the collection chamber 21 through the third communication port.

[0127] In some possible implementations, the third damping device 50 includes a third damping element, which is a ring structure. One end of the third damping element is connected to the suction end of the air pump 30, and the other end of the third damping element is connected to the dust box 20. The suction end of the air pump 30 is connected to the collection chamber 21 through the inner cavity of the third damping element.

[0128] Thus, the third damping device 50 has a relatively simple structure, occupies less space, and is relatively easy to assemble.

[0129] For example, the third damping element can be connected to the suction end of the air pump 30 and the dust box 20 by adhesive bonding.

[0130] For example, the third damping element can be a ring-shaped sleeve structure. The two ends of the third damping element can be respectively sleeved on the connector of the air pump 30 and the connector of the dust box 20, and clamped to the connector of the air pump 30 and the connector of the dust box 20, so as to realize the connection between the third damping element and the air pump 30 and the dust box 20.

[0131] For example, the material of the third damping element may include, but is not limited to, damping materials such as silicone, rubber, nylon, and foam.

[0132] For example, the third damping element seals the gap between the suction end of the air pump 30 and the dust box 20, so that the suction end of the air pump 30 is sealed to the dust box 20 through the third damping element.

[0133] For example, the third damping element can be sealed to the air intake end of the air pump 30 and the dust box 20 by means of sealant, sealant, etc., or it can be sealed to the air intake end of the air pump 30 and the dust box 20 by fitting with the connector of the air pump 30 and the connector of the dust box 20.

[0134] In some other possible embodiments, the third damping device 50 may also be a hydraulic damper or a pneumatic damper. In this case, the third damping device 50 has a flow channel connecting the intake end of the air pump 30 and the collection chamber 21.

[0135] In some examples, the cleaning mechanism includes a second damping device 600 and a third damping device 50.

[0136] In some examples where the cleaning mechanism includes a third damping device 50, the second damping device 600 may not be provided between the dust box 20 and the air duct structure 400. That is, the cleaning mechanism may not include the second damping device 600.

[0137] In some examples where the cleaning mechanism includes the second damping device 600, the third damping device 50 may not be provided between the dust box 20 and the air pump 30. That is, the cleaning mechanism may not include the third damping device 50.

[0138] In some other possible implementations, the end of the air duct structure 400 away from the housing 100 may also be a sealed structure, and the cleaning chamber 110 and the collection chamber 21 may be connected by other air ducts.
