[0030] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0031] In the description of the embodiments of the present application, the directions or positional relationships of "up", "down", "front" and "back" are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] See also Figures 1 to 3 An embodiment of the present application provides a base assembly, which includes a mobile cleaning device 100 and a base in any one embodiment of the present application.

[0033] See also Figure 3 The base provided in the embodiment of the present application includes a shell 1 and a sealing head 2.

[0034] See also Figures 1 to 3 The housing 1 has an air outlet 1a and a receiving chamber 1b for receiving the mobile cleaning device 100. The receiving chamber 1b can provide a storage space for the mobile cleaning device 100.

[0035] See also Figure 3 and Figure 4 The sealing head 2 is formed with an interface 2a and a ventilation duct 2b connected with the interface 2a, and the ventilation duct 2b is sealed and connected with the air supply port 1a. In this way, the joint between the ventilation duct 2b and the air supply port 1a will not leak air and cause noise.

[0036] Please continue reading Figure 3 and Figure 4 The sealing head 2 has a contact surface 2c surrounding the outer periphery of the interface 2a, the interface 2a is used to communicate with the air inlet 100a of the mobile cleaning device 100, and the contact surface 2c is used to seal and abut against the outer periphery of the air inlet 100a. The air inlet 100a enters the dust box of the mobile cleaning device 100 to collect the dust in the dust box into the dust collecting part of the base.

[0037] The mobile cleaning device 100 is disposed in the accommodating chamber 1b so as to be able to enter and exit. For example, the mobile cleaning device 100 can enter the accommodating chamber 1b to collect dust. After the mobile cleaning device 100 has finished collecting dust, it can exit the accommodating chamber 1b to clean the surface to be cleaned.

[0038] The mobile cleaning device 100 includes a body and a dust box. The body is formed with an air inlet 100a and a dust outlet. The air inlet 100a and the dust outlet are both connected to the dust box. The dust box is used to receive dust collected during the cleaning process of the mobile cleaning device 100. The air inlet 100a is used to send airflow into the dust box. The dust outlet is used to discharge dust and airflow in the dust box.

[0039] The base comprises a dust collecting part, and the dust discharge port is communicated with the air inlet of the dust collecting part. The dust collecting part is used to receive dust discharged from the dust discharge port.

[0040] In one embodiment, the base includes a fan, the inlet of the fan can be connected to the air outlet of the dust collecting part, and the outlet of the fan is connected to the air supply port 1a. The dust collection working principle of the base of the present application is as follows: during the operation of the fan, the airflow generated by the fan enters the air supply port 1a through the outlet, and the airflow from the air supply port 1a flows through the ventilation duct 2b, the interface 2a, the air inlet 100a and the dust box in sequence. The airflow blows the dust in the dust box so that the dust can flow with the airflow, and the airflow carrying the dust enters the dust collecting part through the dust exhaust port and the air inlet. After being filtered by the dust collecting part, the dust is collected in the dust collecting part and becomes a clean airflow again. The clean airflow enters the inlet of the fan through the air outlet of the dust collecting part. In this way, during the operation of the fan, the dust in the dust box can be collected in the dust collecting part through the continuous circulation of the airflow. The airflow generated by the fan blows the dust in the dust box, and the inlet of the fan is connected to the air outlet of the dust collecting part to generate negative pressure in the dust collecting part, which can more thoroughly clean the dust in the dust box and avoid dust residue in the dust box during the dust collection process.

[0041] In the related art, the position where the mobile cleaning device stays each time it enters the accommodating chamber will be different. If the air supply port is directly connected to the air inlet of the mobile cleaning device, air leakage gaps are likely to exist between the surrounding parts of the air supply port and the surrounding parts of the air inlet, and the wind speed is faster at the air inlet, resulting in abnormally high-frequency noise during the dust collection process.

[0042] The base provided in the embodiment of the present application is provided with a sealing head 2 between the air supply port 1a of the shell 1 and the air inlet 100a of the mobile cleaning device 100, and the ventilation duct 2b of the sealing head 2 is sealed and connected with the air supply port 1a, and the contact surface 2c of the sealing head 2 can be sealed and abutted with the periphery of the air inlet 100a. In this way, the contact surface 2c and the surface of the peripheral part of the air inlet 100a are in surface contact with each other, so that the surrounding part of the air inlet 100a and the surrounding part of the interface 2a are sealed, thereby avoiding the existence of air leakage gaps and reducing the noise during the dust collection process.

[0043] In one embodiment, the sealing head 2 is a flexible structure. The flexible structure is a structure that can be elastically deformed under the abutting force of the mobile cleaning device 100 against the sealing head 2. In this way, when the mobile cleaning device 100 abuts against the sealing head 2, the interaction force between the mobile cleaning device 100 and the sealing head 2 can drive the sealing head 2 to elastically deform, and the elastic force of the sealing head 2 drives the contact surface 2c to fit the surface of the peripheral part of the air inlet 100a, so that the contact surface 2c and the surface of the peripheral part of the air inlet 100a always maintain surface contact.

[0044] The sealing head 2 may be made of a flexible material, including but not limited to rubber and / or silicone and the like.

[0045] In one embodiment, please refer to Figure 3 and Figure 4 The sealing head 2 includes an annular lip 21 and a support ring 22, and the space defined by the support ring 22 is a part of the ventilation duct 2b. In other words, the inner space enclosed by the annular support ring 22 is a part of the ventilation duct 2b.

[0046] The lip 21 is connected to the support ring 22 and bent inwards. The opening formed by the lip 21 is the interface 2a, and the outer surface of the lip 21 away from the support ring 22 is the contact surface 2c. The opening formed by the annular lip 21 is the interface 2a. The lip 21 is connected to the support ring 22 and bent inwards. In this way, there is a gap between the inner surface of the support ring 22 and the inner surface of the lip 21. In the process of the airflow from the air supply port 1a blowing toward the air inlet 100a, part of the airflow will enter the gap and have a tendency to move toward the air inlet 100a. The airflow in the gap exerts a pressing force on the lip 21 toward the mobile cleaning device 100. The pressing force drives the contact surface 2c to press against the surrounding area of ​​the air inlet 100a, thereby strengthening the sealing effect between the lip 21 and the mobile cleaning device 100.

[0047] In one embodiment, please refer to Figure 3 and Figure 4The area of ​​the flow cross section of the support ring 22 gradually expands from the direction away from the interface 2a to the direction close to the interface 2a. In other words, the area of ​​the flow cross section of the support ring 22 gradually expands along the flow direction of the airflow in the ventilation duct 2b, so that the inner surface of the support ring 22 plays a guiding role, so that the airflow from the air supply port 1a can smoothly enter the interval space.

[0048] The flow cross section is a cross section perpendicular to the streamline cluster, that is, the airflow of the present application. For example, when the streamline clusters are not parallel to each other, the flow cross section is a curved surface; when the streamline clusters are parallel straight lines, the flow cross section is a plane.

[0049] In one embodiment, please refer to Figure 4 , the angle α between the support ring 22 and the lip 21 is less than 90°. Specifically, the angle α between the inner surface of the support ring 22 and the inner surface of the lip 21 is less than 90°. Exemplarily, with the plane parallel to the axial direction of the sealing head 2 as the cross-section, the shape formed by the support ring 22 and the lip 21 is a V-shape that opens inward. On the one hand, the volume of the interval space between the support ring 22 and the lip 21 is small, which makes it easier for the airflow from the air supply port 1a to fill the interval space and drive the lip 21 to press against the surface of the outer peripheral part of the air inlet 100a; on the other hand, the inner surface of the support ring 22 plays a guiding role, so that the airflow from the air supply port 1a can smoothly enter the interval space.

[0050] The axial direction of the sealing head 2 refers to the axial direction of the sealing head 2 along the flow direction of the airflow. For example, the sealing head 2 is a rotating body structure around the axis or an axisymmetric structure.

[0051] In one embodiment, please refer to Figure 3 and Figure 4 , the sealing head 2 includes an annular deformable ring 23, the deformable ring 23 is connected to the end of the support ring 22 away from the lip 21, the space defined by the deformable ring 23 is a part of the ventilation duct 2b, and part of the wall surface of the deformable ring 23 protrudes outward or recesses inward to form a corrugated section 231. In other words, the internal space enclosed by the annular deformable ring 23 is a part of the ventilation duct 2b, and the space in the deformable ring 23 is connected to the space in the support ring 22. The corrugated section 231 is a part of the deformable ring 23 that protrudes outward or recesses inward. The corrugated section 231 can increase the elasticity of the deformable ring 23 along the axial direction. When the mobile cleaning device 100 abuts against the sealing head 2, the corrugated section 231 can bend or shrink accordingly as the position of the mobile cleaning device 100 changes, so that the lip 21 can adapt to the air inlet 100a with a certain position change, and improve the reliability of the docking connection between the interface 2a and the air inlet 100a.

[0052] In some embodiments, the number of the corrugated section 231 is one. In other embodiments, the number of the corrugated section 231 is multiple.

[0053] For example, in one embodiment, please refer to Figure 4 The deformation ring 23 includes two annular walls arranged and connected in the axial direction, one of which is connected to the end of the support ring 22 away from the lip 21, and the end where the two annular walls are connected protrudes outward to form a corrugated section 231. In this way, when the mobile cleaning device 100 abuts against the sealing head 2, the two annular walls are subjected to an axial extrusion force, and the end where the two annular walls are connected moves outward, and the other ends of the two annular walls approach each other, that is, the corrugated section 231 contracts in the axial direction. The outwardly protruding corrugated section 231 makes it easier for the deformation ring 23 to quickly recover its deformation when the mobile cleaning device 100 removes the extrusion force.

[0054] In one embodiment, the wall thickness of the deformable ring 23 is smaller than the wall thickness of the support ring 22. That is, the wall thickness of the corrugated section 231 is smaller than the wall thickness of the support ring 22. On the one hand, the wall thickness of the deformable ring 23 is relatively small, and the structural strength of the deformable ring 23 is relatively low. When the sealing head 2 is squeezed by the mobile cleaning device 100, the deformable ring 23 is bent or contracted accordingly in advance so that the contact surface 2c can adapt to the surface of the peripheral part of the air inlet 100a. On the other hand, the wall thickness of the support ring 22 is relatively large, and the structural strength of the support ring 22 is relatively high, so that the support ring 22 can well support the lip 21, and avoid the airflow in the interval space impacting the support ring 22, causing the support ring 22 to deform and cause the lip 21 to shift.

[0055] In one embodiment, please refer to Figure 3 and Figure 4 The sealing head 2 includes an annular main body ring 24, which is connected to one end of the deformation ring 23 away from the support ring 22. The space defined by the main body ring 24 is a part of the ventilation duct 2b. The wall thickness of the main body ring 24 is greater than the wall thickness of the deformation ring 23, and the main body ring 24 is connected to the housing 1. In other words, the internal space enclosed by the annular main body ring 24 is a part of the ventilation duct 2b, and the space inside the main body ring 24, the space inside the deformation ring 23 and the space inside the support ring 22 are connected in sequence. The wall thickness of the main body ring 24 is relatively large, and the structural strength of the main body ring 24 is relatively high, so that the main body ring 24 and the housing 1 can be firmly connected.

[0056] In one embodiment, please refer to Figure 3 and Figure 4 The ventilation duct 2b defined by the main body ring 24 is in sealed communication with the air outlet 1a. Specifically, the main body ring 24 is sealed and penetrated in the air outlet 1a, and the deformation ring 23, the support ring 22 and the lip 21 are all located in the accommodating cavity 1b.

[0057] In one embodiment, the sealing head 2 may be connected to the housing 1 in a non-detachable manner or in a detachable manner.

[0058] For example, the sealing head 2 can be screwed or clamped to the housing 1 .

[0059] In one embodiment, please refer to Figure 3 and Figure 4 The outer peripheral surface of the sealing head 2 is formed with an annular clamping groove 2d, and the peripheral side wall of the air supply port 1a is inserted into the clamping groove 2d. Specifically, the clamping groove 2d has a radial opening that opens radially outward, and the peripheral side wall of the air supply port 1a is inserted into the clamping groove 2d through the radial opening of the clamping groove 2d. In this way, the two groove surfaces of the clamping groove 2d along the axial direction clamp the peripheral side wall of the air supply port 1a, restricting the sealing head 2 from axially separating from the air supply port 1a, so that the sealing head 2 and the housing 1 are clamped.

[0060] In one embodiment, please refer to Figure 3 and Figure 4 The card groove 2d is formed on the outer peripheral surface of the main body ring 24.

[0061] In one embodiment, please refer to Figure 3 and Figure 4 The base includes a conversion head 3, which is formed with a conversion port 3a. The portion of the sealing head 2 is located on the side of the housing 1 away from the interface 2a to form a pad 25. The pad 25 surrounds the outer periphery of the air supply port 1a, and the surrounding part of the conversion port 3a abuts against the pad 25. The pad 25 can seal the gap between the air supply port 1a and the conversion port 3a, realize the sealed connection between the conversion head 3 and the housing 1, and reduce the risk of noise generated between the conversion head 3 and the housing 1.

[0062] For example, the conversion head 3 can be used to connect the fan duct to deliver the airflow generated by the fan to the air outlet 1a, so as to facilitate the arrangement of the fan position according to the needs and reduce the design difficulty.

[0063] In one embodiment, please refer to Figure 3 and Figure 4 The main body ring 24 is located at a side of the housing 1 away from the interface 2a to form a pad 25. The pad 25 can be a side wall of the slot 2d. The conversion head 3 is located outside the housing 1.

[0064] In one embodiment, please refer to Figure 4 The end surface of the backing plate 25 facing the conversion head 3 is formed with a receiving groove 25a, and the surrounding part of the conversion port 3a is located in the receiving groove 25a. In this way, the circumferential surface of the receiving groove 25a can limit the radial movement of the surrounding part of the conversion port 3a, thereby improving the sealing reliability between the conversion head 3 and the housing 1.

[0065] In one embodiment, the flow cross section area of ​​the conversion port 3a is smaller than the flow cross section area of ​​the pad 25. The airflow from the conversion port 3a can smoothly enter the ventilation duct 2b, avoiding the pad 25 blocking the airflow and causing wind damage.

[0066] It should be noted that, since the pad 25 surrounds the outer periphery of the air supply port 1a, the pad 25 has a flow port connected to the air supply port 1a, and the flow port is the area where the ventilation duct 2b is connected to the conversion port 3a. The area of ​​the flow cross section of the pad 25 is the area of ​​the flow cross section of the flow port.

[0067] In one embodiment, the conversion head 3 and the housing 1 can be detachably connected.

[0068] For example, the conversion head 3 and the housing 1 may be connected by screws or bolts.

[0069] For example, in some embodiments, the dust collecting member may form a dust collecting chamber, and the air inlet and the air outlet are both connected to the dust collecting chamber. The dust collecting chamber is used to receive dust from the dust box.

[0070] In some embodiments, the base includes a filter screen covering the air outlet, wherein the mesh of the filter screen is used to circulate air flow and block dust.

[0071] In some embodiments, the base includes a filter bag disposed in the dust collecting member, the filter bag is located in the dust collecting chamber and is covered on the periphery of the air inlet. The airflow carrying dust enters the filter bag through the air inlet, and the filter bag filters the airflow carrying dust so that the dust remains in the filter bag, and the clean air flows out from the air outlet through the mesh of the filter bag.

[0072] In some embodiments, the filter bag can be a disposable device. After the filter bag is used, the filter bag can be taken out and discarded, and replaced with a new filter bag. In other embodiments, the filter bag can be reused. In other words, the user cleans the dust in the filter bag and then installs the filter bag into the dust collection chamber, which is energy-saving and environmentally friendly.

[0073] In some embodiments, the dust collecting member may be detachable. For example, the dust collecting member may be detachably connected to the housing 1 or other structures of the base, such as a frame. In this way, when it is necessary to clean the dust in the dust collecting member, the dust collecting member may be taken out for cleaning. It is understood that the dust collecting member may also be non-detachable, for example, a filter bag may be used, and the dust may be cleaned by removing the filter bag.
