[0021] 0This application provides a wet cleaning device. Figure 1-Figure 5 , wet cleaning device 100

[0022] The conveying assembly 20 and the brush assembly 30 may be included. The brush assembly 30 is connected to one end of the conveying assembly 20 and is used to clean the object to be cleaned. For example, the object to be cleaned may be a fabric, such as a sofa, a mattress, a carpet or a curtain. The brush assembly 30 can be connected to the object to be cleaned.

[0023] The conveying assembly 20 can drive the brush head assembly 305 to move to clean different areas or positions of the object to be cleaned.

[0024] When cleaning the object to be cleaned, the user can directly hold the conveying assembly 20, or hold the handle connected to the conveying assembly 20. The brush head assembly 30 can be detachably connected to the conveying assembly 20 to facilitate cleaning of dirt remaining in the suction channel after the brush head assembly 30 is detached from the conveying assembly 20.

[0025] See also Figure 4 、 Figure 5The conveying assembly 20 is provided with a first liquid supply channel 231 and a second liquid supply channel 241. The first liquid supply channel 231 is configured to supply liquid to the object to be cleaned. The liquid may include one or more of clean water, a composition, a concentrated detergent and a diluted detergent. By spraying liquid onto the object to be cleaned through the first liquid supply channel 231, the stains on the object to be cleaned can be removed, making the object to be cleaned cleaner. The second liquid supply channel 241 is configured to supply liquid for self-cleaning of the brush head assembly 30 to the brush head assembly 30. By supplying liquid to the brush head assembly 30 through the second liquid supply channel 241, dirt adhering to the brush head assembly 30 can be cleaned, and dirt can be prevented from remaining on the brush head assembly 30 to generate odor or block the suction channel, thereby enabling the wet cleaning device 100 to have a self-cleaning function.

[0026] See also Figure 1 The wet cleaning device 100 may also include a connecting assembly 10 and a main unit (not shown). The connecting assembly 10 is connected between the conveying assembly 20 and the main unit. The connecting assembly 10 is connected to the end of the conveying assembly 20 away from the brush head assembly 30. The connecting assembly 10 may include one or more of a hose, a rigid tube, a shrinkable tube, or a foldable tube. The main unit may include a power assembly (not shown), a liquid supply tank (not shown), and a recovery tank (not shown). The liquid supply tank is used to supply liquid to the first liquid supply channel 231 and the second liquid supply channel 241, and the recovery tank is used to collect dirt generated when the brush head assembly 30 cleans the object to be cleaned. The liquid supply tank and the recovery tank may be detachably mounted on the main unit to facilitate adding liquid to the liquid supply tank or cleaning dirt from the recovery tank. The power assembly is used to provide power for the operation of the wet cleaning device 100. For example, the power assembly can vacuum the suction channel, allowing the brush head assembly 30 to absorb dirt from the object to be cleaned; for another example, the power assembly can pressurize the liquid, spraying it onto the object to be cleaned.

[0027] See also Figure 1-Figure 4The delivery assembly 20 includes a first control valve 40. For example, the first control valve 40 can be set at one end of the delivery assembly 20 away from the brush head assembly 30, so that the first control valve 40 can avoid the user's grip on the delivery assembly 20 to prevent accidental touching of the first control valve 40. The first control valve 40 is provided with a liquid inlet 411, a first liquid outlet 412, and a second liquid outlet 413. The liquid inlet 411 is used to receive liquid, the first liquid outlet 412 is connected to the first liquid supply channel 231, and the second liquid outlet 413 is connected to the second liquid supply channel 241. The first liquid outlet 412 and the second liquid outlet 413 are respectively connected to the first liquid supply channel 231 and the second liquid supply channel 241, so that the liquid can be diverted through the first control valve 40. Only one liquid supply pipe is needed to supply liquid to the two liquid supply channels, which can reduce the number of liquid supply pipes, thereby reducing the space occupied by the liquid supply pipes in the internal space of the connecting assembly 10, and can increase the area of the air duct, thereby reducing the possibility of air duct blockage or residual garbage. The first control valve 40 is configured to control the connection state between the liquid inlet 411 and at least one of the first liquid supply channel 231 and the second liquid supply channel 241. The first control valve 40 can control whether at least one of the first liquid supply channel 231 and the second liquid supply channel 241 is connected to the liquid inlet 411 or not, and thus can control the opening or closing of at least one of the liquid supply channels. The first control valve 40 is set to control the connection state between the liquid inlet 411 and at least one of the first liquid supply channel 231 and the second liquid supply channel 241, so that the first control valve 40 can control the opening or closing of at least one of the liquid supply channels. At least one of the liquid supply channels does not need to be provided with a control valve, thereby reducing the number of control valves, reducing the internal space occupied by the conveying assembly 20, and helping to reduce the volume of the conveying assembly 20.

[0028] The first control valve 40 may include a transfer tube that can switch between the first liquid supply channel 231 and the second liquid supply channel 241, thereby controlling whether at least one of the first liquid supply channel 231 and the second liquid supply channel 241 is connected to the liquid inlet 411. Figure 3As shown, the first control valve 40 includes a first valve body 41 and a first control member 42. The first valve body 41 can be formed as a whole, or it can be formed by multiple parts that are processed separately and then assembled and connected. The liquid inlet 411, the first liquid outlet 412 and the second liquid outlet 413 are opened in the first valve body 41. The first control member 42 is at least partially accommodated in the first valve body 41. The first control member 42 is arranged on the communication path between the liquid inlet 411 and the first liquid supply channel 231 and the second liquid supply channel 241, so that the first control member 42 can control the communication state between the liquid inlet 411 and at least one of the first liquid supply channel 231 and the second liquid supply channel 241. The first control member 42 is movably connected to the first valve body 41. The first control member 42 is movably connected to the first valve body 41 so that the first control member 42 can have a certain movement stroke relative to the first valve body 41. The first control member 42 has at least two control positions relative to the first valve body 41. The first control member 42 is configured to switch between the control positions to control the communication between the liquid inlet 411 and at least one of the first liquid supply channel 231 and the second liquid supply channel 241. By configuring the first control member 42 to switch between the control positions to control whether at least one of the first liquid supply channel 231 and the second liquid supply channel 241 is connected to the liquid inlet 411 or not, the control method of the first control valve 40 is more convenient, thereby improving the usability of the wet cleaning device 100.

[0029] The wet cleaning device 100 can be provided with only one control valve to control the connectivity of the two liquid supply channels and simultaneously control the output of the liquid in the two liquid supply channels. In one embodiment, the first control member 42 has three control positions relative to the first valve body 41. The control positions include a first control position, a second control position, and a third control position. When the first control member 42 is in the first control position, the first control member 42 controls the liquid inlet 411 to be connected to the first liquid supply channel 231 and not to be connected to the second liquid supply channel 241. In this case, the first liquid supply channel 231 can be in a state of use where liquid is sprayed onto the object to be cleaned. When the first control member 42 is in the second control position, the first control member 42 controls the liquid inlet 411 to be connected to the second liquid supply channel 241 and not to be connected to the first liquid supply channel 231. In this case, the second liquid supply channel 241 can be in a self-cleaning state where liquid is supplied to the brush head assembly 30. When the first control member 42 is in the third control position, the first control member 42 controls the liquid inlet 411 to be disconnected from the first liquid supply channel 231 and the second liquid supply channel 241. At this time, there is no liquid output, which can be the use state of the wet cleaning device 100 adsorbing dirt on the object to be cleaned. The first control member 42 is set to have three control positions relative to the first valve body 41, so that one control valve can be set to control the connection state of the two liquid supply channels and simultaneously control the output of liquid in the two liquid supply channels, which can reduce the number of control valves. Under normal circumstances, the first control member 42 is in the third control position. Setting the first control member 42 in the third control position under normal circumstances can facilitate the user to control the output of liquid according to usage needs, thereby saving liquid usage and reducing the amount of liquid residual in the object to be cleaned, which can improve the efficiency of adsorbing dirt.

[0030] In one embodiment, the first control member 42 has two control positions relative to the first valve body 41. The control positions include a first control position and a second control position. When the first control member 42 is in the first control position, the first control member 42 controls the liquid inlet 411 to communicate with both the first liquid supply channel 231 and the second liquid supply channel 241. In this case, the first liquid supply channel 231 sprays liquid onto the object to be cleaned, and the second liquid supply channel 241 supplies liquid to the brush head assembly 30 for self-cleaning. When the first control member 42 is in the second control position, the first control member 42 controls the liquid inlet 411 to disconnect from both the first liquid supply channel 231 and the second liquid supply channel 241. In this case, no liquid is output, which can be the state in which the wet cleaning device 100 absorbs dirt from the object to be cleaned. Under normal circumstances, the first control member 42 is in the second control position, which allows the user to control the liquid output according to the user's needs, thereby saving liquid usage and reducing the amount of liquid remaining on the object to be cleaned, thereby improving the efficiency of dirt absorption. The first control member 42 is provided with two control positions relative to the first valve body 41. On the one hand, one control valve can be provided to control the connectivity of the two liquid supply channels and simultaneously control the output of the liquid in the two liquid supply channels, thereby reducing the number of control valves. On the other hand, since the first control member 42 has only two control positions relative to the first valve body 41, the movement stroke of the first valve body 41 is relatively small compared to the first valve body 41 having three control positions, which can reduce the volume of the first control valve 40, thereby reducing the occupation of the internal space of the conveying component 20 by the first control valve 40, which is beneficial to reducing the volume of the conveying component 20.

[0031] The wet cleaning device 100 may also be provided with two control valves to control the connectivity of the two liquid supply channels and simultaneously control the output of liquid in the two liquid supply channels. In one embodiment, the first control member 42 has two control positions relative to the first valve body 41. The control positions include a first control position and a second control position. When the first control member 42 is in the first control position, the first control member 42 controls the liquid inlet 411 to communicate with the first liquid supply channel 231 and disconnect it from the second liquid supply channel 241. In this case, the first liquid supply channel 231 may be in a state of use where liquid is sprayed onto the object to be cleaned. When the first control member 42 is in the second control position, the first control member 42 controls the liquid inlet 411 to communicate with the second liquid supply channel 241 and disconnect it from the first liquid supply channel 231. In this case, the second liquid supply channel 241 may be in a self-cleaning state where liquid is supplied to the brush head assembly 30. The first control member 42 is provided with two control positions relative to the first valve body 41 so that the first control valve 40 can control the connectivity of the two liquid supply channels. Under normal circumstances, the first control member 42 is located in one of the first control position and the second control position, and the liquid inlet 411 is kept in communication with the first liquid supply channel 231 and one of the second liquid supply channel 241. For example, under normal circumstances, the first control member 42 is located in the first control position. Generally speaking, the frequency of the wet cleaning device 100 in the use state of spraying liquid is greater than the frequency of the wet cleaning device 100 in the self-cleaning state, that is, the frequency of the wet cleaning device 100 needing to perform self-cleaning is relatively low. The first control member 42 is set to the first control position under normal circumstances, so that the liquid inlet 411 is kept in communication with the first liquid supply channel 231 under normal circumstances, which can facilitate the operation of spraying liquid on the object to be cleaned with relatively high frequency. Please refer to Figure 2-Figure 4The wet cleaning device 100 further includes a second control valve 50, which is disposed on a liquid supply channel that is normally connected to the liquid inlet 411. The second control valve 50 is used to control the opening and closing of the liquid supply channel. The second control valve 50 can be spaced apart from the first control valve 40 and mounted on the delivery assembly 20 at an end thereof proximal to the brush head assembly 30. Normally, the second control valve 50 can be closed to facilitate user control of liquid output according to user needs, thereby conserving liquid usage, reducing the amount of liquid remaining on the object to be cleaned, and improving the efficiency of dirt absorption. By setting a second control valve 50 on the liquid supply channel that is normally connected to the liquid inlet 411, the second control valve 50 can control the output of liquid in one of the liquid supply channels, and the first control valve 40 can control the output of liquid in the other liquid supply channel, so that the first control valve 40 and the second control valve 50 can work in combination to control the output of liquid in the two liquid supply channels; since the first control member 42 has only two control positions relative to the first valve body 41, compared with the first valve body 41 having three control positions, the movement stroke of the first valve body 41 is relatively small, which can reduce the volume of the first control valve 40, thereby reducing the occupation of the internal space of the conveying component 20 by the first control valve 40, which is beneficial to reducing the volume of the conveying component 20.

[0032] The first control valve 40 can be an electric valve. For example, the first control valve 40 is a solenoid valve, and the first control valve 40 is provided with a touch key, which can switch the control position of the first control valve 40, thereby controlling the connection between the liquid inlet 411 and at least one of the first liquid supply channel 231 and the second liquid supply channel 241. Alternatively, the first control valve 40 is a mechanical valve, and the first control member 42 is configured to move relative to the first valve body 41 under the action of an external force, so that the first control member 42 switches between various control positions. The first control member 42 is configured to switch the control position under the action of an external force, that is, the first control member 42 can change the movement stroke under the action of an external force. The first control valve 40 is a mechanical valve, which can reduce the cost of the first control valve 40 compared to an electric valve and has better reliability.

[0033] See also Figure 3 、 Figure 5 The conveying assembly 20 is provided with a first suction channel 211, and the brush head assembly 30 is provided with a second suction channel 341 communicating with the first suction channel 211, so that the dirt adsorbed by the brush head assembly 30 can be transferred to the recovery box via the second suction channel 341 and the first suction channel 211. The cross-sectional area of the second suction channel 341 in the direction perpendicular to the airflow can be smaller than the cross-sectional area of the first suction channel 211 in the direction perpendicular to the airflow, so that the brush head assembly 30 can exert a greater suction force on the dirt.

[0034] The conveying assembly 20 can be an integral structure. For example, the conveying assembly 20 can be integrally formed by an injection molding process, and the integrally formed conveying assembly 20 has good integrity. Alternatively, the conveying assembly 20 is a split structure, such as Figure 2-Figure 5 As shown, the conveying assembly 20 includes a handle body 21 and a handle cover 22. The handle body 21 is provided with a first suction channel 211, and the handle cover 22 is provided on one side of the handle body 21. The handle cover 22 can be fixed to the handle body 21 by fasteners (such as screws or bolts). The handle cover 22 and the handle body 21 are enclosed to form an installation cavity 221. The installation cavity 221 can be used to install the first control valve 40 and the second control valve 50. The handle cover 22 and the handle body 21 are enclosed to form an installation cavity 221. The conveying assembly 20 is a split structure, so that the installation cavity 221 is formed by two open parts. On the one hand, it can facilitate the assembly of components in the installation cavity 221; on the other hand, compared with the closed integrated installation cavity 221, it can also reduce the processing difficulty of the conveying assembly 20, thereby facilitating the processing of the conveying assembly 20.

[0035] The first liquid supply channel 231 and the second liquid supply channel 241 can be processed on the handle body 21 or the handle cover 22, that is, holes are opened on the handle body 21 or the handle cover 22 along the length direction of the conveying assembly 20 to form the first liquid supply channel 231 and the second liquid supply channel 241. Alternatively, as Figure 2 、 Figure 4 As shown, the delivery assembly 20 includes a first liquid supply pipe 23 and a second liquid supply pipe 24. The first liquid supply pipe 23 and the second liquid supply pipe 24 are at least partially mounted in the mounting cavity 221. A first liquid supply channel 231 and a second liquid supply channel 241 are respectively disposed in the first liquid supply pipe 23 and the second liquid supply pipe 24. Similarly, the first liquid supply pipe 23 and the second liquid supply pipe 24 are disposed independently of the handle body 21 and the handle cover 22, which can reduce the difficulty of manufacturing the delivery assembly 20 and facilitate the processing of the delivery assembly 20.

[0036] See also Figure 1-Figure 3 The delivery assembly 20 also includes a liquid supply head 25. A third mounting hole 224 is defined in the handle cover 22, and the liquid supply head 25 is at least partially mounted in the mounting cavity 221. One end of the liquid supply head 25 is connected to the first liquid supply tube 23, while the other end of the liquid supply head 25 is exposed to the handle cover 22 through the third mounting hole 224. This allows liquid from the first liquid supply channel 231 to be sprayed from the liquid supply head 25 toward the object to be cleaned. The liquid supply head 25 can be integrally formed or constructed from multiple components that are separately manufactured and then assembled and connected.

[0037] See also Figure 1-Figure 3The brush head assembly 30 includes a brush head 31 and a self-cleaning liquid supply member 32. The brush head 31 is attached to one side of the self-cleaning liquid supply member 32. The brush head 31 is used to clean the object to be cleaned, and the self-cleaning liquid supply member 32 is used to self-clean the brush head assembly 30. The self-cleaning liquid supply member 32 defines a first self-cleaning liquid supply hole 323 and a second self-cleaning liquid supply hole 324 that are connected to the second liquid supply channel 241. The first self-cleaning liquid supply hole 323 opens toward the brush head 31, and the second self-cleaning liquid supply hole 324 is connected to the second suction channel 341. The opening of the first self-cleaning liquid supply hole 323 is arranged to face the brush head 31, so that the first self-cleaning liquid supply hole 323 can spray liquid toward the brush head 31, thereby realizing self-cleaning of the brush head 31; at the same time, the second self-cleaning liquid supply hole 324 is arranged to be connected to the second suction channel 341, so that the second self-cleaning liquid supply hole 324 can spray liquid toward the second suction channel 341, thereby cleaning the second suction channel 341 and preventing dirt from remaining in the second suction channel 341 to generate odor or block the suction channel.

[0038] See also Figure 1-Figure 3 The brush head assembly 30 includes a housing 33 and a cover 34. The self-cleaning liquid supply member 32 and the brush head 31 are mounted on one end of the housing 33. The cover 34 is disposed on one side of the housing 33. The cover 34 and the housing 33 enclose a second suction channel 341. The second suction channel 341 is formed by the cover 34 and the housing 33, so that the second suction channel 341 is formed by an open two-part enclosure. Compared with a closed, integrated suction channel, this can reduce the difficulty of manufacturing the brush head assembly 30.

[0039] The brush head 31 is mounted on one end of the housing 33, and the cover 34 is mounted on one side of the housing 33, so that the second suction channel 341 formed by the cover 34 and the housing 33 is located on one side of the brush head 31, resulting in the flow direction of the liquid flowing to the brush head 31 through the first self-cleaning liquid supply hole 323 being different from the flow direction of the liquid flowing to the second suction channel 341 through the second self-cleaning liquid supply hole 324, that is, the liquid needs to change its flow direction before it can be sprayed into the second suction channel 341, and the fluid will reduce its speed when changing its flow direction, which may affect the self-cleaning effect of the second suction channel 341. In one embodiment, if Figure 6As shown, the self-cleaning liquid supply member 32 includes a first self-cleaning liquid supply member 321 and a second self-cleaning liquid supply member 322. A first self-cleaning liquid supply hole 323 and a second self-cleaning liquid supply hole 324 are respectively provided in the first self-cleaning liquid supply member 321 and the second self-cleaning liquid supply member 322. The brush head 31 is attached to one side of the first self-cleaning liquid supply member 321, and the second self-cleaning liquid supply member 322 is arranged around the other side of the first self-cleaning liquid supply member 321 away from the brush head 31. A liquid supply cavity 325 is formed between the second self-cleaning liquid supply member 322 and the first self-cleaning liquid supply member 321. The second self-cleaning liquid supply hole 324 is connected to the second liquid supply channel 241 through the liquid supply cavity 325. By setting the second self-cleaning liquid supply part 322 and the first self-cleaning liquid supply part 321 to enclose a liquid supply cavity 325, the liquid supply cavity 325 can have a larger volume, thereby forming a buffer space for the liquid, which can reduce the flow resistance of the fluid, thereby reducing the speed loss of the liquid flowing to the second suction channel 341, and improving the self-cleaning effect of the second suction channel 341.

[0040] See also Figure 3 The first valve body 41 is at least partially accommodated in the mounting cavity 221. The first valve body 41 is connected to one side of the handle body 21. The handle cover 22 defines a first mounting hole 222, and the first control member 42 is disposed in the first mounting hole 222. Providing the first control member 42 in the first mounting hole 222 allows the first control member 42 to be exposed to the outside of the handle cover 22 through the first mounting hole 222, thereby facilitating a user's application of force to the first control member 42, thereby changing the control position of the first control member 42.

[0041] The movable connection between the first control member 42 and the first valve body 41 can be a rotational connection, so that the user can apply torque to the first control member 42 to change the relative angle between the first control member 42 and the first valve body 41, thereby changing the control position of the first control member 42 relative to the first valve body 41. The movable connection between the first control member 42 and the first valve body 41 can also be a translational connection, such as Figure 3 As shown, the first control member 42 is slidably connected to the first valve body 41, allowing the user to apply pressure or tension to the first control member 42 to change the relative displacement between the first control member 42 and the first valve body 41, thereby changing the control position of the first control member 42 relative to the first valve body 41. When the first control member 42 is in the first control position, the outer edge of the end of the first control member 42 away from the first valve body 41 is flush with the outer edge of the handle cover 22; when the first control member 42 is in the second control position, the end of the first control member 42 away from the first valve body 41 is located within the first mounting hole 222. The outer edge of the first control member 42 at its maximum stroke is flush with the outer edge of the handle cover 22, making it difficult for the user to touch the first control member 42 when holding the conveying assembly 20, thereby reducing the possibility of accidental triggering of the first control valve 40.

[0042] The first control member 42 may be assembled in the first valve body 41 by interference fit. When the control position of the first control member 42 needs to be changed, the user can apply pressure or tension to the first control member 42 to change the relative position between the first control member 42 and the first valve body 41. In one embodiment, Figure 3 As shown, the first control valve 40 also includes a first reset member 43, which is sleeved outside the first control member 42, and the opposite ends of the first reset member 43 respectively abut the first control member 42 and the first valve body 41. The first reset member 43 is elastic and can be a spring or rubber. When the first control member 42 switches from the first control position to the second control position, the first reset member 43 undergoes elastic deformation under the action of an external force; when the external force is removed, the elastic deformation of the first reset member 43 decreases and drives the first control member 42 to switch to the first control position, so that the first control member 42 is in the first control position under normal conditions. By providing the first reset member 43, the first control member 42 automatically remains in the first control position under the drive of the first reset member, which can facilitate the output control operation of the liquid.

[0043] See also Figure 3 The first control valve 40 further includes a first sealing member 44, which is disposed between the first control member 42 and the first valve body 41 and is used to enhance the airtightness of the first control valve 40. The first sealing member 44 can be made of silicone, which has good compressibility and facilitates improving the airtightness of the first control valve 40. The first sealing member 44 can be an O-ring, a sealing gasket, or a combination of the two.

[0044] See also Figure 3The second control valve 50 includes a second valve body 51, a second control member 52, a second reset member 53, and a second sealing member 54. The second control member 52 is at least partially housed within the second valve body 51 and is slidably connected to the second valve body 51. A user can apply pressure or tension to the second control member 52 to change the relative position between the second control member 52 and the second valve body 51, thereby controlling the opening or closing of the first liquid supply channel 231. The second valve body 51 is at least partially housed within the mounting cavity 221. The second valve body 51 is connected to one side of the handle body 21. A second mounting hole 223 is defined in the handle cover 22. The second control member 52 is disposed at the second mounting hole 223, making it convenient for the user to apply force to the second control member 52 to control the opening or closing of the first liquid supply channel 231. The second return member 53 is mounted externally of the second control member 52. Its opposite ends abut the second control member 52 and the second valve body 51, respectively. Driven by the second return member 53, the second control member 52 automatically remains in the closed position, facilitating liquid output control. A second sealing member 54 is disposed between the second control member 52 and the second valve body 51 to enhance the airtightness of the second control valve 50. The second control valve 50 may further include a button 55 connected to the second control member 52 and exposed in the second mounting hole 223. The button 55 is configured to transmit force to the second control member 52.
