It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0042] Please refer to Figure 1 , the embodiments of the present application provide a cleaning device, and the cleaning device includes the base assembly 100 and the mobile cleaning machine 200 in any one of the embodiments of the present application.

[0043] The mobile cleaning machine 200 includes a machine body, a dust box and a cleaning member. The cleaning member and the dust box are both arranged on the machine body, and the machine body has a dust exhaust port connected to the dust box.

[0044] The mobile cleaning machine 200 can be moved and can clean the surface to be cleaned during the movement. The cleaning method includes suctioning dust on the surface to be cleaned into the dust box and contacting the cleaning member with the surface to be cleaned to achieve friction cleaning. The dust box is used to hold dust, and the dust outlet is used to discharge dust in the dust box.

[0045] The surface to be cleaned includes but is not limited to the ground and the like.

[0046] Exemplarily, the mobile cleaning machine 200 may be an intelligent mobile cleaning machine. Specifically, the machine body includes a control unit and a walking mechanism, and the control unit may control the walking mechanism to walk autonomously and control the cleaning member to operate autonomously. Taking the walking mechanism as a roller as an example, the control unit controls the roller to roll to drive the mobile cleaning machine 200 to walk autonomously, and during the autonomous walking of the mobile cleaning machine 200, the cleaning member may clean the ground.

[0047] The cleaning parts include but are not limited to roller brushes and / or rags and the like.

[0048] See also Figures 1 to 3 An embodiment of the present application provides a base assembly 100 , which includes a base 110 , a dust collection and drying channel 120 , and a fan 130 .

[0049] Please continue reading Figures 1 to 3 ,as well as Figure 9 The base 110 is formed with a dust suction port 110a and a drying air port 110b, and the dust suction port 110a is used to communicate with the dust discharge port of the mobile cleaning machine 200. The dust collection and drying channel 120 is connected with the dust suction port 110a and the drying air port 110b, and the fan 130 is arranged in the dust collection and drying channel 120. The dust suction port 110a is used to communicate with the dust discharge port to collect dust in the dust box to the dust collection and drying channel 120. The airflow in the dust collection and drying channel 120 is blown to the cleaning parts through the drying air port 110b, which is used to dry the cleaning parts of the mobile cleaning machine 200.

[0050] The dust collection and drying channel 120 can filter the airflow from the dust suction port 110a. Exemplarily, the dust collection and drying channel 120 has a filter bin for filtering the airflow from the dust suction port 110a. The dust suction port 110a is used to communicate with the dust discharge port to collect dust in the dust box into the filter bin. In this way, the dust in the dust box is collected in the dust collection and drying channel 120, thereby reducing the number of times the user dumps the dust box.

[0051] The dust collection and drying working principle of the base assembly 100 of the present application is as follows: During the operation of the fan 130, the fan 130 drives the air flow to flow through the dust box, the dust discharge port, the dust suction port 110a, the dust collection and drying channel 120, and the drying air outlet 110b in sequence. The dust debris in the dust box enters the dust collection and drying channel 120 along with the air flow. During the process of the air flow flowing through the dust collection and drying channel 120, the heat generated by the fan 130 will heat the air flow, causing the air flow to rise in temperature. Therefore, the dirty air flow from the dust suction port 110a becomes the heated clean air flow after being filtered and heated by the dust collection and drying channel 120, and the heated clean air flow blows towards the cleaning part through the drying air outlet 110b to achieve the purpose of drying the cleaning part.

[0052] For the base assembly 100 provided in the embodiment of the present application, the dust collection and drying channel 120 communicates with the dust suction port 110a and the drying air outlet 110b. The fan 130 is arranged in the dust collection and drying channel 120. The fan 130 operates to drive the air flow to flow from the dust suction port 110a to the drying air outlet 110b. The dust suction port 110a communicates with the dust discharge port to suck and accommodate the dust debris in the dust box into the dust collection and drying channel 120. Since heat will be generated during the operation of the fan 130, the heat of the fan 130 can be used to heat the air flow flowing through the dust collection and drying channel 120, increasing the temperature of the air flow flowing through the dust collection and drying channel 120. The heated clean air flow blows towards the cleaning part from the drying air outlet 110b, realizing the function of drying the cleaning part. With such a design, on the one hand, the dust suction port 110a and the drying air outlet 110b share the dust collection and drying channel 120. The dust suction port 110a provides the dust collection function for the mobile cleaner 200, and the drying air outlet 110b provides the function of drying the cleaning part for the mobile cleaner 200, which plays the role of saving components, having a compact structure, and reducing costs; on the other hand, the heat generated by the operation of the fan 130 can increase the temperature of the air flow in the dust collection and drying channel 120, which can not only meet the heat dissipation requirement of the fan 130 but also meet the requirement of increasing the temperature of the air flow, saving energy and being environmentally friendly.

[0053] In one embodiment, please refer to Figure 1 , a receiving cavity 110c is formed in the base 110, and the mobile cleaner 200 is disposed in the receiving cavity 110c in a manner that it can enter and exit. The receiving cavity 110c is used to accommodate the mobile cleaner 200. In this way, the base assembly 100 provides the receiving function for the mobile cleaner 200.

[0054] Exemplarily, in one embodiment, please refer to Figure 9 , the drying air outlet 110b communicates with the receiving cavity 110c so that the air flow from the drying air outlet 110b blows towards the cleaning part.

[0055] Exemplarily, in one embodiment, the dust suction port 110a communicates with the receiving cavity 110c. In this way, the dust discharge port of the mobile cleaner 200 in the receiving cavity 110c can be conveniently docked with the dust suction port 110a.

[0056] In one embodiment, an inlet and outlet for the mobile cleaning machine 200 to enter and exit can be formed on the front side of the base 110, and the inlet and outlet is communicated with the storage cavity 110c. The rear side of the base assembly 100 is usually close to the wall, and the space on the front side of the base assembly 100 is relatively open, facilitating the mobile cleaning machine 200 to enter and exit the storage cavity 110c.

[0057] In one embodiment, the blower 130 includes an impeller and a dust collection motor, and the dust collection motor is connected to the impeller to drive the impeller to rotate. The impeller rotates to drive the air flow. The heat generated during the operation of the motor is used to heat the air flow in the dust collection and drying channel 120.

[0058] In one embodiment, please refer to Figures 2 to 4 and Figure 9 The dust collection and drying channel 120 includes a dust collection container 121 and a drying air duct 122. The dust collection container 121 has an air inlet 121a and an air outlet 121b. The air inlet 121a is communicated with the dust suction port 110a, and the drying air duct 122 is communicated with the drying air outlet 110b and the air outlet 121b. The blower 130 is arranged in the drying air duct 122. The dust collection container 121 is used to collect the dust and debris carried by the air flow from the dust suction port 110a. The air flow from the dust suction port 110a first passes through the dust collection container 121 for dust collection to form a clean air flow, and then the clean air flow enters the drying air duct 122. The blower 130 is located downstream of the dust collection container 121 along the air flow direction in the dust collection and drying channel 120, so as to avoid the blower 130 contacting the dust and debris as much as possible.

[0059] Exemplarily, in one embodiment, please refer to Figure 2 and Figure 3 The air inlet 121a and the dust suction port 110a can be communicated through a dust suction pipe 124.

[0060] In one embodiment, please refer to Figures 2 to 4 and Figure 9 The number of drying air outlets 110b is multiple. The drying air duct 122 includes a main air duct 1221 and multiple branch air ducts 1222. The main air duct 1221 is communicated with the air outlet 121b, and the branch air ducts 1222 are communicated with the main air duct 1221 and the drying air outlets 110b. The air flow enters the main air duct 1221 through the air outlet 121b, and then enters the multiple drying air outlets 110b respectively through the multiple branch air ducts 1222. Exemplarily, the mobile cleaning machine 200 includes multiple cleaning parts, and each drying air outlet 110b corresponds to one cleaning part, so that the corresponding cleaning parts can be dried through the multiple drying air outlets 110b, improving the drying efficiency.

[0061] In one embodiment, please refer to Figures 2 to 4, the dust collection container 121 is disposed above the base 110. With such a design, there is a relatively large space above the base 110, and without significantly increasing the floor area of the base assembly 100, the volume of the dust collection container 121 can be relatively large to increase the dust collection capacity.

[0062] In one embodiment, please refer to Figures 2 to 4 and Figure 9 , an air outlet 121b is formed at the rear part of the dust collection container 121, and an air inlet 121a is formed at one side of the dust collection container 121 in the left-right direction. The drying air duct 122 can be disposed at the rear side of the dust collection container 121. The drying air duct 122 can be relatively large to facilitate the installation of a blower 130 therein. In addition, the distance between the air outlet 121b and the drying air inlet 110b can be relatively close, and the length of the drying air duct 122 can be relatively short to facilitate the air flow in the drying air duct 122 to enter the drying air inlet 110b as soon as possible. The air inlet 121a is formed at one side of the dust collection container 121 in the left-right direction, which is convenient for the piping of the dust suction pipe 124.

[0063] In one embodiment, please refer to Figures 2 to 4 , the dust collection and drying channel 120 includes a filter member 123 slidably disposed in the dust collection container 121. A sliding opening for sliding the filter member 123 is provided at the front side of the dust collection container 121. The filter member 123 is located at the air inlet 121a to filter and collect the dust particles in the air flow from the air inlet 121a. The sliding opening is provided at the front side of the dust collection container 121 to facilitate the user to slide the filter member 123 through the sliding opening from the front side. For example, when it is necessary to clean or replace the filter member 123, the user slides out the filter member 123 through the sliding opening from the front side, and the cleaned filter member 123 is put back into the dust collection container 121 through the sliding opening or a new filter member 123 is put into the dust collection container 121.

[0064] The filter member 123 can be a filter bag. For example, the filter bag covers the periphery of the air inlet 121a. The mesh of the filter bag is used for air flow and blocking dust particles. The air flow carrying dust particles enters the filter bag through the air inlet 121a. The filter bag filters the air flow carrying dust particles, so that the dust particles are retained in the filter bag, and the clean air flow passes through the mesh of the filter bag and flows out from the air outlet 121b.

[0065] In some embodiments, the filter bag can be a disposable device. After the filter bag is used up, the filter bag can be taken out and discarded, and a new filter bag can be replaced. In other embodiments, the filter bag can be reused. That is, after the user cleans the dust particles in the filter bag, the filter bag is assembled into the dust collection container 121, which is energy-saving and environmentally friendly.

[0066] In one embodiment, please refer to Figures 2 to 4, a part of the dust collection and drying channel 120 is located above the base 110, and the fan 130 is located above the base 110. Specifically, the fan 130 is located within the part of the dust collection and drying channel 120 that is above the base 110. The space above the base 110 is relatively open. With such a design without increasing the floor area of the base assembly 100, the volume of the dust collection and drying channel 120 can be as large as possible, which is not only convenient for dust collection but also convenient for arranging the fan 130 within the dust collection and drying channel 120.

[0067] Exemplarily, in one embodiment, please refer to Figures 2 to 4 , the dust collection container 121 is located above the base 110, a part of the drying air duct 122 is located above the base 110 and is connected to the air outlet 121b of the dust collection container 121, and the fan 130 is arranged within the part of the drying air duct 122 that is above the base 110.

[0068] In one embodiment, please refer to Figures 2 to 4 and Figure 9 , both the dust suction port 110a and the drying air inlet 110b are located on the peripheral side wall of the base 110. On the one hand, the dust suction port 110a is located on the peripheral side wall of the base 110, which is convenient for the dust suction port 110a to be docked and communicated with the dust discharge port of the mobile cleaner 200. On the other hand, the drying air inlet 110b is located on the peripheral side wall of the base 110, and the airflow of the drying air inlet 110b can smoothly blow towards the cleaning parts of the mobile cleaner 200, reducing the interference of other structural parts on the base assembly 100.

[0069] Exemplarily, in one embodiment, please refer to Figure 2 , Figure 3 and Figure 9 , both the dust suction port 110a and the air inlet 121a are located on the same side of the dust collection container 121 in the left - right direction, and the dust suction pipe 124 extends upward from the dust suction port 110a to the air inlet 121a. The main air duct 1221 extends downward from the air outlet 121b at the rear of the dust collection container 121 to the rear of the base 110, and the two drying air inlets 110b are respectively located on both sides of the main air duct 1221 in the left - right direction, and the branch air duct 1222 connects the main air duct 1221 and the drying air inlet 110b.

[0070] In one embodiment, please refer to Figures 2 to 6, the base assembly 100 includes a switch device 140. The dust collection and drying channel 120 is formed with a ventilation opening 120a communicating with the outside, and the switch device 140 can selectively open or close the ventilation opening 120a. When the ventilation opening 120a is in the closed state, the airtightness of the dust collection and drying channel 120 is good, and it is easy to form a negative pressure in the dust collection and drying channel 120 when the fan 130 works, so as to facilitate sucking the dust debris in the dust box. When the ventilation opening 120a is in the open state, the outside air can enter the dust collection and drying channel 120 through the ventilation opening 120a, thereby increasing the air volume to improve the drying efficiency.

[0071] Exemplarily, in one embodiment, during the dust collection process, the ventilation opening 120a can be closed through the switch device 140, and the fan 130 can operate at a high speed. The heat generated by the fan 130 is driven by the air flow to the drying air outlet 110b to dry the cleaning part while collecting dust. In this way, the cleaning part can be dried within a short time during dust collection, reducing the humidity of the cleaning part. When it is necessary to dry the cleaning part, the ventilation opening 120a can be opened through the switch device 140, and the fan 130 can operate at a low speed. The heat generated by the fan 130 is driven by the air flow to the drying air outlet 110b to dry the cleaning part. In this way, the cleaning part can be dried for a long time, making the cleaning part dry more thoroughly.

[0072] It should be understood that the high speed here is relative to the low speed, and the high speed is higher than the low speed.

[0073] In one embodiment, please refer to Figure 3 、 Figure 6 、 Figure 7 and Figure 9 , the dust collection and drying channel 120 includes a dust collection container 121 and a drying air duct 122. The dust collection container 121 has an air inlet 121a and an air outlet 121b. The air inlet 121a is communicated with the dust suction port 110a. The drying air duct 122 is communicated with the drying air outlet 110b and the air outlet 121b. The fan 130 is arranged in the drying air duct 122. A ventilation opening 120a is formed at the connection between the drying air duct 122 and the dust collection container 121. The ventilation opening 120a is located downstream of the air outlet 121b. The switch device 140 can selectively open one of the ventilation opening 120a and the air outlet 121b. In other words, if the switch device 140 opens the ventilation opening 120a, the air outlet 121b will be synchronously closed; if the switch device 140 opens the air outlet 121b, the ventilation opening 120a will be synchronously closed. That is to say, if one of the ventilation opening 120a and the air outlet 121b is opened, the other of the ventilation opening 120a and the air outlet 121b will be closed by the switch device 140.

[0074] In this embodiment, the ventilation opening 120a is located downstream of the air outlet 121b along the direction of air flow in the dust collection and drying channel 120. That is to say, the air flow passes through the air outlet 121b first and then through the ventilation opening 120a. During the dust collection process, the ventilation opening 120a can be closed and the air outlet 121b can be opened through the switching device 140. The ventilation opening 120a cannot introduce external air into the dust collection and drying channel 120, and the dust collection and drying channel 120 maintains a good negative pressure, achieving efficient dust collection and reducing the humidity of the cleaning member. In the case where it is necessary to dry the cleaning member, the ventilation opening 120a can be opened and the air outlet 121b can be closed through the switching device 140. In this way, the air flow in the dust collection container 121 cannot enter the drying air duct 122 through the air outlet 121b, further reducing the risk of dust debris that may leak in the dust collection container 121 being blown towards the cleaning member and improving the cleanliness of the air flow used for drying.

[0075] In some embodiments, the drying air duct 122 is formed with a ventilation opening 120a.

[0076] In other embodiments, the dust collection container 121 is formed with a ventilation opening 120a. Since the ventilation opening 120a is located downstream of the air outlet 121b, when the air outlet 121b is closed by the switching device 140, the external air introduced by the ventilation opening 120a can still enter the drying air duct 122.

[0077] In one embodiment, the ventilation opening 120a is located upstream of the fan 130 along the direction of air flow. In this way, during the operation of the fan 130, external air can enter the dust collection and drying channel 120 through the ventilation opening 120a under the action of negative pressure.

[0078] In one embodiment, please refer to Figure 6 , the switching device 140 includes a seal 141 and a sliding frame 142. The sliding frame 142 is slidably disposed in the ventilation opening 120a. The seal 141 is disposed on the sliding frame 142. The sliding frame 142 makes a linear reciprocating motion to drive the seal 141 to seal or avoid the ventilation opening 120a. In the case where it is necessary to close the ventilation opening 120a, the sliding frame 142 drives the seal 141 to make a forward linear motion to seal the ventilation opening 120a; in the case where it is necessary to open the ventilation opening 120a, the sliding frame 142 drives the seal 141 to make a reverse linear motion to avoid the ventilation opening 120a. The sliding frame 142 is slidably disposed in the ventilation opening 120a. The sliding frame 142 can slide under the constraint of the wall surface of the ventilation opening 120a. The wall surface of the ventilation opening 120a plays a role of guiding and limiting. In this way, a guide rail for restricting the sliding track of the sliding frame 142 does not need to be designed additionally, simplifying the structure.

[0079] It should be noted that the forward and reverse directions are two opposite directions.

[0080] The manner in which the seal 141 seals the vent 120a is not limited. Exemplarily, in one embodiment, please refer to Figure 6 , the seal 141 can be pressed against the surrounding part of the vent 120a to seal the vent 120a. That is to say, the seal 141 is in sealing contact with the surface of the surrounding part of the vent 120a to achieve sealing.

[0081] In one embodiment, please refer to Figure 4 and Figure 6 , the seal 141 is disposed at the part of the sliding carriage 142 located within the dust collection and drying channel 120. The seal 141 being located within the dust collection and drying channel 120 can reduce the probability of external objects contacting the seal 141.

[0082] In one embodiment, please refer to Figures 4 to 7 , the sliding carriage 142 includes a frame body 1421 and a baffle 1422. The frame body 1421 is slidably disposed through the vent 120a.

The baffle 1422 is located within the dust collection and drying channel 120 and is disposed on the side of the frame body 1421 away from the vent 120a. The frame body 1421 slides along the vent 120a, and the baffle 1422 and the surrounding part of the vent 120a jointly clamp the seal 141, so that the seal 141 presses against the surrounding part of the vent 120a to achieve the function of sealing the vent 120a.

[0083] In one embodiment, please refer to Figure 6 and Figure 7 , the switching device 140 includes a driving motor 143 and a reversing member 144. The reversing member 144 connects the driving motor 143 and the sliding carriage 142, and the reversing member 144 converts the rotation of the driving motor 143 into a linear reciprocating motion of the sliding carriage 142. The driving motor 143 provides the power for the sliding carriage 142 to slide, improving the degree of automation. The reversing member 144 is used to convert the motion mode.

[0084] In one embodiment, please refer to Figure 6 , one end of the reversing member 144 is connected to the driving motor 143. The reversing member 144 is in threaded cooperation or tooth cooperation with the sliding carriage 142 to convert the rotation of the driving motor 143 into a linear reciprocating motion of the sliding carriage 142. For example, the reversing member 144 can be a lead screw with an external thread, and the sliding carriage 142 is formed with an internal thread adapted to the external thread of the lead screw, and the external thread is in threaded cooperation with the internal thread. Another example is that the reversing member 144 is formed with a first tooth portion, and the sliding carriage 142 is formed with a second tooth portion cooperating with the first tooth portion, and the first tooth portion and the second tooth portion are in tooth cooperation. The driving motor 143 drives the reversing member 144 to rotate, and the reversing member 144 is in threaded cooperation or tooth cooperation with the sliding carriage 142, so that the sliding carriage 142 makes a linear reciprocating motion.

[0085] In one embodiment, please refer to Figures 4 to 6 , a ventilation opening 120a is formed on one side wall of the dust collection and drying channel 120 in the left - right direction, and the driving motor 143 is located on one side of the dust collection and drying channel 120 in the left - right direction. Exemplarily, please refer to Figure 6 , the ventilation opening 120a is formed on one side wall of the dust collection container 121 in the left - right direction. With such a design, it is possible to avoid, as much as possible, the sliding frame 142 and the driving motor 143 from further increasing the height of the base assembly 100. Through reasonable layout, the base assembly 100 can meet the requirements of a smaller floor area and a lower height.

[0086] In one embodiment, please refer to Figures 4 to 7 , the switch device 140 includes an elastic member 145. The elastic member 145 is connected to the sliding frame 142, and the elastic force of the elastic member 145 keeps the seal member 141 in a state of sealing the ventilation opening 120a. The elastic member 145 can improve the sealing reliability.

[0087] The elastic member 145 includes, but is not limited to, a tension spring or a compression spring.

[0088] In one embodiment, please refer to Figures 4 to 7 , the elastic member 145 is a tension spring. The two tension springs are respectively located on both sides of the driving motor 143. One end of the tension spring is connected to the base 110, and the other end of the tension spring is connected to the sliding frame 142. Exemplarily, the ventilation opening 120a extends in the up - down direction, the driving motor 143 is located on the side of the sliding frame 142 away from the ventilation opening 120a in the left - right direction, and the two tension springs are respectively located on both sides of the driving motor 143 in the up - down direction. With such a design, the elastic member 145 can apply force evenly, reduce the risk of the sliding frame 142 shifting, and enable the sliding frame 142 to slide more smoothly.
