DETAILED DESCRIPTION

[0058] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0059] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0060] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0061] See also Figure 1 As shown, a cleaning system such as a sweeper and a scrubber usually includes a cleaning host 200 and a base station 300. The cleaning host 200 includes a suction source 210 and a recovery box 220. The suction source 210 is a negative pressure generating structure such as a fan. When the cleaning host 200 is working, the suction source 210 can drive the recovery box 220 to generate negative pressure to suck external dirt (such as dirt generated during the cleaning process or the self-cleaning process) into the recovery box 220; the base station 300 is mainly used for the recovery and treatment of dirt in the cleaning host 200.

[0062] In the prior art, a suction source 210 is usually provided on the base station 300. When the cleaning host 200 and the base station 300 are docked, the base station 300 is connected to the recycling box 220, and under the action of the suction source 210 on the base station 300, a negative pressure is formed inside the base station 300 to suck the dirt in the recycling box 220 to the base station 300. The suction source 210 acting on the recycling box 220 needs to be provided on both the cleaning host 200 and the base station 300, which is costly, complex in structure, and not conducive to installation and maintenance.

[0063] Preferably, the utility model provides an air duct switching structure 100, which is used in the above cleaning system, and the air duct switching structure 100 is arranged on the cleaning host 200 or the base station 300. Figure 2 and Figure 3 As shown, the air duct switching structure 100 includes a first air duct 110 and a second air duct 120. The air duct switching structure 100 can selectively present the first air duct 110 or the second air duct 120. The first air duct 110 is suitable for connecting the suction source 210 and the recovery box 220 of the cleaning host 200, and the second air duct 120 is suitable for connecting the suction source 210 and the base station 300 when the cleaning host 200 and the base station 300 are docked.

[0064] When the cleaning host 200 is performing sewage suction work, the air duct switching structure 100 presents the first air duct 110, and the suction source 210 acts on the recovery box 220 to generate negative pressure in the recovery box 220 and suck external sewage; when it is necessary to discharge the sewage in the recovery box 220, the cleaning host 200 is docked with the base station 300, the air duct switching structure 100 presents the second air duct 120, and the suction source 210 acts on the base station 300 to generate negative pressure in the base station 300 and suck the sewage in the recovery box 220.

[0065] With the above structure, a single suction source 210 can draw dirt into the recovery box 220, or draw dirt in the recovery box 220 into the base station 300, effectively reducing the production cost of the cleaning system, simplifying the structure of the cleaning system, and making assembly and maintenance more convenient.

[0066] Further, the air duct switching structure 100 is a hollow structure, and the first air duct 110 and the second air duct 120 are both formed inside the air duct switching structure 100. The air duct switching structure 100 has an axial direction and a radial direction, and one of the first air duct 110 and the second air duct 120 extends along the radial direction of the air duct switching structure 100, and the other at least extends along the axial direction of the air duct switching structure 100, that is, the first air duct 110 and the second air duct 120 intersect inside the air duct switching structure 100, and the extension directions of the first air duct 110 and the second air duct 120 are at least partially different.

[0067] By adopting the above structure, one of the air ducts extends along the radial direction of the air duct switching structure 100, which can effectively reduce the path of the air duct, improve the suction efficiency, and reduce the loss of the suction source 210 during operation; wherein the other air duct at least extends along the axial direction of the air duct switching structure 100, so that during the extension process of the first air duct 110 and the second air duct 120, as the extension path increases, the ends of the two air ducts that are not connected to the suction source 210 can move away from each other, so that there is sufficient docking space between the two air ducts. When the recovery box 220 and the base station 300 are docked to the air duct switching structure 100, the recovery box 220 and the base station 300 are effectively prevented from limiting each other.

[0068] Furthermore, combined with Figure 3 and Figure 4 As shown, the air duct switching structure 100 includes an outer shell 130 and a switching member 140. The outer shell 130 is a hollow structure. The switching member 140 is movably connected in the outer shell 130 and can cooperate with the outer shell 130 to form a first air duct 110 and a second air duct 120. The switching member 140 can move relative to the outer shell 130 to drive the air duct switching structure 100 to present the first air duct 110 or the second air duct 120.

[0069] The switching member 140 can specifically use rotational motion and / or translational motion to achieve the switching of the air duct. In this embodiment, the switching member 140 is preferably rotatably connected to the housing 130. The switching member 140 achieves the switching of the air duct by a rotation operation. With the rotational connection, the switching member 140 is easy to operate, and the connection structure between the switching member 140 and the housing 130 is simple. The axial direction of the air duct switching structure 100 is specifically the direction of the rotation axis of the switching member 140, and the radial direction of the air duct switching structure 100 is specifically multiple directions perpendicular to the direction of the rotation axis of the switching member 140.

[0070] Further, as a preferred embodiment, the housing 130 is generally cylindrical, and a wind cavity 131 is formed inside the housing. The switching member 140 is a cylindrical structure adapted to the wind cavity 131. The inner circumferential wall of the wind cavity 131 is in close contact with the outer circumferential wall of the switching member 140. The switching member 140 can rotate around its axis under the guidance of the inner circumferential wall of the wind cavity 131. With the above structure, the rotation of the switching member 140 is more reliable, and when installing the switching member 140, it only needs to be directly installed into the wind cavity 131, and no additional rotating connection structure is required between the two, which further simplifies the overall structure.

[0071] The switching member 140 partially passes through the axial end wall of the housing 130 and extends outside the housing 130 to connect with an external driving structure (not shown). The driving structure can use a rotating motor to drive the switching member 140 to rotate automatically, thereby improving the degree of intelligence.

[0072] Furthermore, the housing 130 is provided with a first docking port 132, a second docking port 133, and a third docking port 134 that are connected to the air cavity 131. The first docking port 132 can be connected to the suction source 210, the second docking port 133 can be connected to the recovery box 220, and the third docking port 134 can be connected to the base station 300. The switching member 140 can close the second docking port 133 or the third docking port 134 in response to the rotation operation. When the third docking port 134 is closed, the first docking port 132 and the second docking port 133 are connected to form the first air duct 110. When the second docking port 133 is closed, the first docking port 132 and the third docking port 134 are connected to form the second air duct 120.

[0073] Specifically, the switching member 140 has a sealed inner cavity, and a plurality of openings 141 connected to the inner cavity are provided on the outer wall of the switching member 140. During the rotation of the switching member 140, the outer wall of the switching member 140 can block the third docking port 134 and drive its opening 141 to correspond to the first docking port 132 and the second docking port 133, so as to form a conductive first air duct 110 between the first docking port 132 and the second docking port 133, or the outer wall of the switching member 140 can block the second docking port 133 and drive its opening 141 to correspond to the first docking port 132 and the third docking port 134, so as to form a conductive second air duct 120 between the first docking port 132 and the third docking port 134.

[0074] Preferably, the axial dimension of the housing 130 is larger than its radial dimension to improve the reliability of the switch 140 after installation. The first docking port 132, the second docking port 133 and the third docking port 134 are all opened on the outer peripheral wall of the housing 130 to avoid setting the docking port on the axial end wall of the housing 130. Correspondingly, the opening 141 is also opened on the outer peripheral wall of the switch 140. Since the axial dimension of the housing 130 is relatively long, the path of the air duct can be shortened by opening the docking port on the outer peripheral wall; and since the area of ​​the outer peripheral wall of the housing 130 is much larger than the area of ​​the end wall, the housing 130 has enough space to open the docking port and adjust the position of the docking port to improve the compatibility with the recycling box 220 and the base station 300; in addition, the above structure can also avoid the driving structure connected to the switching member 140 from obstructing the docking port and the components connected to the docking port.

[0075] Further, in one embodiment, the first air duct 110 extends along the radial direction of the air duct switching structure 100, the first pairing port 132 and the second pairing port 133 are both located on the radial side wall of the housing 130 in the air duct switching structure 100, and the first pairing port 132 and the second pairing port 133 are not staggered in the axial direction of the air duct switching structure 100, thereby avoiding the existence of an axially extending portion and excessive bends in the first air duct 110, shortening the path of the first air duct 110, and allowing the airflow to flow more smoothly in the first air duct 110. Preferably, the opening directions of the first pairing port 132 and the second pairing port 133 can be parallel, at which time the first air duct 110 will have no bends, and the airflow and suction efficiency will be in the best state.

[0076] Correspondingly, the second air duct 120 extends axially and radially along the air duct switching structure 100, and the first docking port 132 and the third docking port 134 are both located on the radial side wall of the shell 130 in the air duct switching structure 100, and the first docking port 132 and the third docking port 134 are staggered axially in the air duct switching structure 100, that is, the second docking port 133 and the third docking port 134 have a larger spacing in the axial direction of the air duct switching structure 100, which can facilitate the docking of the recycling box 220 and the base station 300 and avoid mutual limitation between the two, and can adapt to more models of recycling boxes 220 and base stations 300, thereby improving versatility.

[0077] Of course, in other embodiments, the first air duct 110 may also extend along the axial direction and radial direction of the air duct switching structure 100, the first docking port 132 and the second docking port 133 are both located on the radial side wall of the housing 130 in the air duct switching structure 100, and the first docking port 132 and the second docking port 133 are staggered in the axial direction of the air duct switching structure 100. Correspondingly, the second air duct 120 extends along the radial direction of the air duct switching structure 100, the first docking port 132 and the third docking port 134 are both located on the radial side wall of the housing 130 in the air duct switching structure 100, and the first docking port 132 and the third docking port 134 are not staggered in the axial direction of the air duct switching structure 100.

[0078] Since the actual use process usually has a high requirement for the dirt suction of the cleaning host 200, preferably, in this embodiment, the first air duct 110 extends along the radial direction of the air duct switching structure 100, and the second air duct 120 extends along the axial and radial directions of the air duct switching structure 100 to ensure the dirt suction efficiency and cleaning ability of the cleaning host 200.

[0079] Further, refer to Figure 6 and Figure 7 As shown, as a preferred embodiment, the air duct switching structure 100 further includes a docking member 150 fixedly connected to the housing 130, a third air duct 151 communicating with the second air duct 120 is formed in the docking member 150, and the third air duct 151 includes a fourth docking port 152 for docking with the base station 300. The docking member 150 can be detachably fixed to the housing 130 by a threaded connector or a clamping structure, and one end of the third air duct 151 is connected to the second docking port 133.

[0080] By providing a docking piece 150 that is detachably connected to the housing 130, the adaptability of the air duct switching structure 100 can be improved, so that different docking pieces 150 can be replaced as needed to meet the docking requirements of different models of base stations 300, without having to adjust or replace the entire air duct switching structure 100, thereby reducing costs.

[0081] Preferably, refer to Figures 8 to 10 As shown, the opening direction of the fourth interface 152 is parallel to the docking direction of the air duct switching structure 100 and the base station 300. When the cleaning host 200 is docked with the base station 300, the fourth interface 152 can be synchronously docked to the preset interface of the base station 300, reducing the operation steps and improving the user experience. In addition, when the cleaning host 200 is in the docking state, the fourth interface 152 is preferably arranged downward, and is tightly pressed against the preset interface under the gravity of the cleaning host 200, thereby improving the tightness of the connection between the fourth interface 152 and the preset interface.

[0082] Specifically, a pipe joint 310 is provided on the base station 300, and the pipe joint 310 includes a first end 311 and a second end 312. The first end 311 is connected to the airflow pipeline in the base station 300 by end-to-end docking, plug-in, etc., and the second end 312 is located outside the base station 300 and is used to connect and cooperate with the docking piece 150, so that the suction source 210 can act on the airflow pipeline to suck the dirt in the recovery box 220 to the sewage pipeline of the base station 300.

[0083] The docking piece 150 can be sleeved outside the second end 312 or passed through the second end 312 to achieve the connection between the two, that is, when the docking piece 150 is sleeved outside the second end 312, the inner contour of the fourth docking port 152 is adapted to the outer contour of the second end 312; when the docking piece 150 is passed through the second end 312, the outer contour of one end of the fourth docking port 152 formed on the docking piece 150 is adapted to the inner contour of the second end 312.

[0084] Since the fourth docking port 152 on the docking piece 150 is arranged downward, and correspondingly, the opening on the second end 312 is arranged upward, in this embodiment, the docking piece 150 preferably adopts a solution of being sleeved outside the second end 312, so that while satisfying the same flow effect, the size of the opening of the second end 312 can be designed to be smaller, thereby reducing the probability of dirt entering the second end 312, and the sealing and aesthetics are better after docking.

[0085] Preferably, the cross section of the first end 311 is circular to facilitate docking with the airflow pipeline inside the base station 300. The cross section of the second end 312 is non-circular to prevent fooling and ensure accurate docking between the second end 312 and the docking piece 150. The cross section of the second end 312 can be square or oval, etc., and is preferably oval in this embodiment to improve the smoothness of circulation.

[0086] Preferably, a sealing structure may be provided on the inner peripheral wall of the fourth docking port 152 and / or the outer peripheral wall of the second end portion 312 to improve the sealing performance therebetween. The material of the sealing structure includes, but is not limited to, rubber, silicone and plastic with a certain elasticity. In this embodiment, at least one flange 3121 is convexly provided on the outer periphery of the second end portion 312. The flange 3121 may be integrally formed with the second end portion 312 or assembled together after being formed separately. After the second end portion 312 is connected to the docking member 150, the flange 3121 is suitable for abutting against the inner wall of the docking member 150 to improve the sealing performance. The flange 3121 is preferably located near the end of the second end portion 312 to avoid affecting the sealing effect due to inadequate connection.

[0087] Further, return Figure 1As shown, the utility model provides a cleaning device, including a cleaning host 200 and an air duct switching structure 100 disposed on the cleaning host 200. Preferably, when the cleaning host 200 is in a cleaning state or a docking state, the first docking port 132 is located above the second docking port 133 and the third docking port 134, thereby effectively reducing the probability of dirt flowing to the suction source 210 along with the suction airflow, and ensuring the normal operation of the suction source 210.

[0088] In addition, the utility model also provides a cleaning system, including a cleaning device, a base station 300 and an air duct switching structure 100, the cleaning device includes a suction source 210 and a recovery box 220, the air duct switching structure 100 is arranged on the cleaning device or the base station 300, the air duct switching structure 100 includes a first air duct 110 and a second air duct 120, the first air duct 110 is suitable for connecting the suction source 210 and the recovery box 220, and the second air duct 120 is suitable for connecting the suction source 210 and the base station 300 when the cleaning host 200 and the base station 300 are docked.

[0089] Since the cleaning host 200 will detach from the base station 300 and move freely during the cleaning operation, preferably, in this embodiment, the air duct switching structure 100 is set on the cleaning host 200. Compared with being set on the base station 300, when the cleaning host 200 performs a cleaning operation in this embodiment, the air duct switching structure 100 can reliably maintain the connectivity between the suction source 210 and the recovery box 220, and avoid the air duct switching structure 100 restricting the movement of the cleaning host 200.
