According to some embodiments of the present invention, referring to fig. 1 to 3, 7 and 26, the sewage tank 4 and the cleaning liquid tank 5 are located at opposite sides of the machine body 1, so that the overall height of the whole machine can be reduced, and the structure of the whole machine is compact and balanced. Alternatively, the sump 4 and the cleaning solution tank 5 are respectively located at the front side and the rear side of the body 1. When the sewage tank 4 is located at the front side of the machine body 1, the main body of the floor brush 8 is also located at the front side of the machine body 1, so that the air flow directly flows upwards into the sewage tank 4 after flowing through the floor brush 8, the air flow path can be reduced, and the air flow loss can be reduced.

Alternatively, referring to fig. 11 and 26, the upper end surface of the cleaning solution tank 5 is higher than the upper end surface of the sewage tank 4. Thus, after the cleaning device 3 is mounted on the sewage tank 4, the overall height of the whole machine can be made lower, and the structural layout of the opposite sides of the whole machine can be made reasonable and attractive.

Alternatively, referring to fig. 1 to 3, 7 and 26, both the cleaning solution tank 5 and the sewage tank 4 are disposed adjacent to the lower end of the body 1. Therefore, the height of the gravity center of the whole machine can be reduced, so that the gravity center of the whole machine is more stable and is closer to the ground, and the load sense of a user is reduced.

According to some embodiments of the invention, fig. 1-3 and 40-45, the cleaning device 3 is located above the sewage tank 4 and on the same side of the machine body 1 as the sewage tank 4. Therefore, the flow path of the air flow can be shortened, the air flow loss is reduced, and meanwhile, the cleaning device 3 is positioned above the sewage tank 4, so that the cleaning device 3 is convenient to assemble and disassemble. In addition, when the cleaning device 3 is located above the sewage tank 4 and both the cleaning device and the sewage tank 4 are located on the front side of the machine body 1, the gravity center of the whole machine can be adjacent to the front side of the machine body 1, and the movement and the use of the whole machine are facilitated.

It should be noted that the directions "front", "rear", "left" and "right" according to the present invention are based on the moving direction of the user when using the wet and dry cleaner 100.

For example, in some embodiments of the present invention, fig. 1 to 3 and 40 to 45, the cleaning device 3 and the sewage tank 4 are both located at the front side of the body 1, and the cleaning liquid tank 5 is located at the rear side of the body 1. Therefore, the gravity center of the whole machine is adjacent to the front side of the machine body 1, the movement and the use convenience of the whole machine are facilitated, and the flow path of the air flow can be further shortened.

Alternatively, fig. 1 to 3 and 40 to 45, in a horizontal direction, an upper portion of the cleaning solution tank 5 is opposite to the cleaning device 3, and a lower portion of the cleaning solution tank 5 is opposite to the sewage tank 4. Thereby, the structures of the opposite sides of the body 1 are made relatively uniform, and the cleaning liquid tank 5 can be made to have a large capacity.

According to some alternative embodiments of the invention, fig. 1-3 and 40-45, the cleaning device 3 is located above the sewage tank 4 and on the same side of the machine body 1 as the sewage tank 4, and in a vertical direction, the center line of the cleaning device 3 and the center line of the sewage tank 4 extend in a vertical direction and coincide. Thereby, the cleaning device 3 can be stably and reliably supported on the sewage tank 4, and the structure of the whole machine is more compact and stable.

Further, in fig. 1 to 3 and 40 to 45, the center line of the cleaning device 3 and the center line of the sewage tank 4 pass through the floor brush 8. Therefore, the structure of the whole machine is compact, the gravity center of the whole machine is adjacent to the front side of the machine body 1, and the movement and the use convenience of the whole machine are facilitated.

According to some embodiments of the invention, referring to fig. 1-3, a cleaning liquid tank 5 is located below the handle 2. Therefore, the gravity center of the whole machine can be close to the lower end of the machine body 1, and the handle 2 can be conveniently held for operation.

When the cleaning device 3 is in the single use mode, the cleaning device 3 and the handle 2 are separated from the machine body 1, and one end of the handle main body 21 is connected with the air inlet 311 a. Under the action of the power assembly 32, the airflow carrying dirt such as dust flows into the cavity of the handle body 21 from the other end of the handle body 21, and flows through the handle body 21, the air inlet 311a and the dust-air separation device 31 in sequence. The separated dust and other solid garbage are recovered in the dust barrel assembly 31, and the relatively clean air flow after dust-gas separation of the dust barrel assembly 31 can be discharged to the external environment through the air outlet 321c on the outer peripheral wall of the power assembly 32.

Therefore, the handle 2 is detachably connected with the machine body 1, the handle main body 21 is in a tubular shape with both ends open, and when the cleaning device 3 is in a single use mode, the cleaning device 3 can be matched with the handle 2 for use, so that the use flexibility of the wet and dry dual-purpose dust collector 100 is enhanced, and meanwhile, the cleanable space range is enlarged. For example, the cleaning device 3 is used in combination with the handle 2 to clean the floor or to perform an overhead operation.

According to some alternative embodiments of the present invention, referring to fig. 1 to 9, a handle 2 is detachably connected to a body 1, a mounting cavity 1a having an open top is formed at an upper end of the body 1, and a lower end of the handle 2 is disposed in the mounting cavity 1 a. Thereby, the handle 2 can be conveniently mounted on the body 1 and the contact area of the handle 2 and the body 1 can be increased. Alternatively, the handle 2 is slidable in the mounting chamber 1a in the extending direction of the body 1. From this, locate the installation cavity 1a of organism 1 through the lower extreme with handle 2 in, make things convenient for the dismouting of handle 2 and can make handle 2 install on organism 1 reliably to through with handle 2 along the extending direction slidable of organism 1, make handle 2 have the lift function, the user can be according to actual demand height in the position of adjustment handle 2, more make things convenient for user's use.

Further, the handle 2 can be locked to the body 1 by a locking assembly, whereby the handle 2 can be locked to the body 1 by the provided locking assembly, and of course, the handle 2 can be unlocked from the body 1 by operating the locking assembly.

In some alternative embodiments of the present invention, referring to fig. 6-10, the locking assembly may include: the lock catch 151 and the lock groove 2a, the release button 152, and the lock spring 153, which are engaged with each other, are provided horizontally movably on the inner side wall of the installation chamber 1a (for example, the lock catch 151 is provided horizontally movably on the left side wall of the installation chamber 1 a), and the lock groove 2a is formed on the side wall of the handle 2 (for example, the lock groove 2a is formed on the left side wall of the handle 2). The release button 152 is provided on the body 1 so as to be movable up and down (for example, the release button 152 is provided on the top end of the body 1 so as to be movable up and down). The release button 152 cooperates with the locking catch 151 to drive the locking catch 151 out of engagement with the locking groove 2a, and the handle 2 is unlocked from the body 1. One end of the locking spring 153 is connected to the body 1 and the other end is connected to the locking buckle 151, and the locking spring 153 is adapted to drive the locking buckle 151 to cooperate with the locking groove 2a so as to lock the handle 2 to the body 1.

Thus, when the release button 152 is pressed downward, the release button 152 moves downward and comes into close contact with the latch 151, so that the release button 152 has an urging force toward the latch 151 away from the latch groove 2a (e.g., the release button 152 has a leftward urging force on the latch 151) by the engagement of the first driving surface 1521 and the second driving surface 1511, so that when the release button 152 is pressed downward, the latch 151 can be driven to move toward the direction away from the latch groove 2a to disengage from the latch groove 2a (e.g., the latch 151 can be driven to move leftward to disengage from the latch groove 2 a), thereby conveniently achieving unlocking of the handle 2, and after the release button 152 is released, the release button 152 can be returned to the original position by the set return spring.

According to some alternative embodiments of the present invention, referring to fig. 4 to 7, a positioning protrusion 23 is provided on a sidewall of the handle 2, and a positioning groove 1b engaged with the positioning protrusion 23 is formed on an inner sidewall of the installation cavity 1 a. Thus, the handle 2 can be conveniently positioned on the body 1 by the cooperation of the positioning protrusion 23 on the handle 2 and the positioning groove 1b on the body 1, and the handle 2 can be positioned and locked on the body 1 by the cooperation of the locking assembly.

For example, in the example of fig. 4 to 7, a positioning protrusion 23 is provided on the front side wall of the handle 2, a positioning groove 1b that mates with the positioning protrusion 23 is formed on the front side wall of the installation cavity 1a, the positioning groove 1b is located at the upper end of the body 1 and penetrates the top of the body 1 upward, and the positioning groove 1b communicates with the installation cavity 1a, and the handle 2 is locked on the body 1 by the above-mentioned locking assembly. When the handle 2 is installed, the lower end of the handle 2 is inserted into the installation cavity 1a, and the positioning protrusion 23 on the handle 2 is matched in the positioning groove 1b on the machine body 1, so that the handle 2 can be positioned. After the handle 2 is positioned, the locking buckle 151 on the machine body 1 is driven by the locking spring 153 to extend into the locking groove 2a, so that the handle 2 can be locked on the machine body 1. When the handle 2 is detached from the body 1, the release button 152 is pressed downward to drive the locking buckle 151 to retract, and the locking buckle 151 is disengaged from the locking groove 2a, at which time the handle 2 is unlocked. The handle 2 is lifted up until the positioning protrusion 23 on the handle 2 is disengaged from the positioning groove 1b on the body 1, the handle 2 can be separated from the body 1, and the release button 152 can be restored to the original position by releasing the release button 152.

According to some embodiments of the present invention, referring to fig. 1 to 4, 11 to 12, and 40 to 46, the cleaning device 3 is detachably provided to the machine body 1, so that the flexibility of use of the wet and dry dual-purpose cleaner 100 can be increased. Referring to fig. 40 to 46, when the cleaning device 3 is in the combined use mode, the cleaning device 3 may be in the wet cleaning mode, the cleaning device 3 is connected to the machine body 1, and the air flow sequentially passes through the dust collection cavity 81a, the sewage tank 4 and the dust canister assembly 31 through the suction inlet 81b under the action of the power assembly 32. Specifically, the cleaning liquid tank 5 in the cleaning liquid supply assembly supplies the cleaning liquid to the shower head 72, the shower head 72 sprays the cleaning liquid onto the floor brush 8 or the surface to be cleaned, and the air flow enters the dust suction chamber 81a through the suction port 81b by the power assembly 32. When the nozzle 72 sprays the cleaning liquid onto the floor brush 8, dirt such as dust is carried in the air flow entering the dust collection cavity 81a through the suction inlet 81b, and the cleaning liquid on the floor brush 8 forms sewage after cleaning the surface to be cleaned and falls into the dust collection cavity 81 a; when the nozzle 72 sprays the cleaning liquid onto the surface to be cleaned, dirt such as dust, sewage, etc. is carried in the air flow entering the suction chamber 81a through the suction port 81 b.

Of course, when the cleaning device 3 is in the combined use mode, the cleaning device 3 may be in the dry cleaning mode, in which case the cleaning liquid flow path of the cleaning liquid supply unit may be shut off, or the cleaning liquid may not be stored in the cleaning liquid supply unit.

Referring to fig. 9, when the cleaning device 3 is in the single use mode, the cleaning device 3 is in the dry cleaning mode, and the cleaning device 3 is separated from the body 1 and used alone. Under the action of the power assembly 32, the air flow carrying dirt such as dust enters the dust barrel assembly 31 from the air inlet 311a for dust-air separation, the separated dust and other solid garbage are recovered in the dust barrel assembly 31, and the relatively clean air flow after dust-air separation of the dust barrel assembly 31 can be discharged to the external environment through the air outlet 321c on the peripheral wall of the power assembly 32. By detachably providing the cleaning device 3 to the machine body 1, the cleaning device 3 can be separated from the machine body 1 and used alone, thereby increasing the flexibility of use of the wet and dry cleaner 100.

Alternatively, when the cleaning device 3 is in the single use mode, the external pipeline can be connected to the air inlet 311a for use.

According to some embodiments of the present invention, referring to fig. 4, 12, 18, 19 and 29, the body 1 is formed with a mating surface 11 adapted to mate with the cleaning device 3, and the mating surface 11 is formed as an inwardly concave arc surface. Therefore, the size of the whole machine in the horizontal direction can be reduced, the use of the whole machine is more convenient, the cleaning device 3 can be reliably contacted with the machine body 1, the whole appearance of the machine body 1 is more attractive, and meanwhile, the disassembly and assembly work of the cleaning device 3 can be conveniently realized due to the good guiding effect of the arc surface.

According to some embodiments of the present invention, referring to fig. 11, the detaching direction (referring to e1 direction in fig. 11) of the cleaning device 3 when separated from the body 1 is parallel or at an acute angle to the extending direction of the body 1. For example, when the wet and dry dual-purpose vacuum cleaner 100 is not in use, the extending direction of the body 1 is in the vertical direction, and the detaching direction of the cleaning device 3 from the body 1 may be in the vertical direction; the detachment direction of the cleaning device 3 when separated from the machine body 1 may also have an angle with the vertical direction, which is an acute angle, which may be between 0-30 °. Thereby, the cleaning device 3 can be quickly separated from the body 1 substantially along the extending direction of the body 1 (for example, the cleaning device 3 can be lifted upward or obliquely upward to separate the cleaning device 3 from the body 1, or the cleaning device 3 can also be pushed downward or obliquely downward to separate the cleaning device 3 from the body 1), so that the separation operation of the cleaning device 3 is easier and more convenient.

For example, in some embodiments of the present invention, referring to fig. 3 and 11, when the cleaning device 3 is provided at the upper portion of the body 1 above the sewage tank 4, the cleaning device 3 may be lifted upward to separate the cleaning device 3 from the body 1. Thereby, the disassembly and assembly of the cleaning device 3 are facilitated.

In some alternative embodiments of the invention, referring to fig. 12-16, the point of attachment of the cleaning device 3 to the body 1 is near the top end of the body 1. Therefore, the connection point of the cleaning device 3 and the machine body 1 can avoid other parts on the starting machine body 1, the connection point between the cleaning device 3 and the machine body 1 is convenient to set, and meanwhile, the disassembly and assembly operations of the cleaning device 3 are also convenient.

In some alternative embodiments of the present invention, referring to fig. 1 to 3, when the cleaning device 3 is attached to the body 1, the top surface of the cleaning device 3 is exposed to the outside of the body 1. Thereby, the portion of the machine body 1 located above the cleaning device 3 is free from any obstruction, and the cleaning device 3 can be lifted directly upward or obliquely upward to separate the cleaning device 3 from the machine body 1 when the cleaning device 3 is separated from the machine body 1.

In some alternative embodiments of the invention, referring to fig. 1-4, 12, 18, 19 and 29, the body 1 is formed with a mating surface 11 adapted to mate with the cleaning device 3, the mating surface 11 being located on the rear side of the cleaning device 3. Thereby, after the cleaning device 3 is mounted on the body 1, the rear side of the cleaning device 3 is enclosed by the mating surface 11 of the body 1, and the other side of the cleaning device 3 is directly exposed to the external environment, thus making the separation operation of the cleaning device 3 easier and more convenient.

According to some embodiments of the present invention, referring to fig. 11 and 17, the bottom of the dust barrel assembly 31 has an air inlet 311a, an air inlet pipe 312 is connected to the air inlet 311a, the top of the sewage tank 4 has an air outlet 4a, and the lower end of the air inlet pipe 312 is inserted into the air outlet 4 a. Thereby, the connection of the dust barrel assembly 31 and the sewage tank 4 is facilitated, and the limit function of the cleaning device 3 in the horizontal direction can be achieved.

Alternatively, the lower end of the air inlet duct 312 is detachably inserted into the air outlet 4 a. Thereby facilitating the separation of the tank 4 from the cleaning device 3.

Alternatively, the air outlet 4a is connected with an air guide duct 41, and the lower end of the air inlet duct 312 is inserted into the air guide duct 41. Thus, the air flow from the sewage tank 4 can be easily guided into the air inlet duct 312 through the air guide duct 41 by the air guide duct 41 provided.

According to some embodiments of the present invention, referring to fig. 12 to 16, the wet and dry vacuum cleaner 100 includes a locking assembly for locking the cleaning device 3 to the body 1, and of course, the cleaning device 3 may be unlocked from the body 1 by operating the locking assembly. The latch assembly includes: the first and second locking portions 141 and 3a, the driving button 142 and the driving spring 143 are engaged with each other. The first locking part 141 is telescopically arranged on the machine body 1, the second locking part 3a is arranged on the cleaning device 3, the driving button 142 is arranged on the machine body 1 in a vertically movable manner, and the driving button 142 is matched with the first locking part 141 to drive the first locking part 141 to retract so as to separate the first locking part 141 and the second locking part 3a from the machine body 1, thereby separating the cleaning device 3 from the machine body 1. One end of the driving spring 143 is connected to the machine body 1 and the other end is connected to the first locking part 141, and the driving spring 143 is adapted to drive the first locking part 141 to protrude so that the first locking part 141 and the second locking part 3a are engaged, thereby locking the cleaning device 3 to the machine body 1.

Thus, when the cleaning device 3 is mounted on the machine body 1, the cleaning device 3 presses the first locking portion 141 such that the first locking portion 141 is retracted into the machine body 1, and after the cleaning device 3 is mounted in place, the first locking portion 141 is extended and engaged with the second locking portion 3a by the driving of the driving spring 143, so that the cleaning device 3 can be locked on the machine body 1. When the cleaning device 3 is detached from the machine body 1, the driving button 142 is pressed such that the driving button 142 moves toward the first locking portion 141 (for example, the driving button 142 is pressed such that the driving button 142 moves downward), the driving button 142 pushes the first locking portion 141 to retract into the machine body 1, the first locking portion 141 is disengaged from the second locking portion 3a, and the cleaning device 3 is unlocked from the machine body 1. At this time, the cleaning device 3 may be lifted or pushed substantially along the extending direction of the body 1 to separate the cleaning device 3 from the body 1, while the driving button 142 is released, and the driving button 142 returns to the initial position. By arranging the lock catch assembly, the cleaning device 3 can be conveniently locked on the machine body 1, and meanwhile, the cleaning device 3 can be conveniently unlocked.

Alternatively, referring to fig. 13 to 15, the second locking portion 3a may be a protrusion provided on the machine body 1, and when the first locking portion 141 is engaged with the second locking portion 3a, the first locking portion 141 is located above the second locking portion 3a and abuts on an upper surface of the second locking portion 3 a. Alternatively, referring to fig. 16, the second locking portion 3a may be a groove formed in the body 1, and the first locking portion 141 may extend into the second locking portion 3a when the first locking portion 141 is engaged with the second locking portion 3 a.

Alternatively, referring to fig. 15 and 16, the driving button 142 has a first engagement slope 1421, the first latch portion 141 has a second engagement slope 1411 engaged with the first engagement slope 1421, and both the first engagement slope 1421 and the second engagement slope 1411 extend obliquely downward in the protruding direction of the first latch portion 141 (e.g., in the back-to-front direction). Thus, when the driving button 142 is pressed, the driving button 142 has a driving force to the first locking portion 141 in a direction away from the second locking portion 3a (for example, the driving button 142 has a rearward driving force to the first locking portion 141) by the engagement of the first engagement slope 1421 of the driving button 142 and the second engagement slope 1411 of the first locking portion 141, and the first locking portion 141 and the second locking portion 3a can be conveniently driven to be disengaged, so that the unlocking of the cleaning device 3 can be conveniently achieved.

For example, when the card slot 1c is provided on the machine body 1, the card projection 35 is provided on the cleaning device 3; when the card slot 1c is provided on the cleaning device 3, the card projection 35 is provided on the body 1. Thereby, the cleaning device 3 can be positioned on the body 1 conveniently by the engagement of the catching groove 1c and the catching protrusion 35.

Alternatively, the cross section of the clamping groove 1c and the cross section of the clamping protrusion 35 are non-circular, and the cross section of the clamping groove 1c is matched with the cross section of the clamping protrusion 35. Since the cross section of the catching groove 1c and the cross section of the catching protrusion 35 are both non-circular, the cleaning device 3 can be prevented from rotating in its circumferential direction.

Further, referring to fig. 12 to 14, a catching groove 1c is formed on the body 1 and a top of the catching groove 1c is opened, a catching protrusion 35 is formed on the cleaning device 3, and both a cross section of the catching groove 1c and a cross section of the catching protrusion 35 are T-shaped. Thus, when the cleaning device 3 is mounted on the machine body 1, the cleaning device 3 can be mounted from top to bottom, and the locking protrusion 35 on the cleaning device 3 is inserted into the locking groove 1c downward through the opening at the top of the locking groove 1 c.

In this process, the first locking part 141 is retracted into the machine body 1 under the pressing of the cleaning device 3, and after the cleaning device 3 is installed in place, the first locking part 141 is extended under the action of the driving spring 143 and is engaged with the second locking part 3a, so that the cleaning device 3 can be positioned and locked on the machine body 1 by the combined action of the positioning structure and the locking assembly. When the cleaning device 3 is detached from the machine body 1, the driving button 142 is pressed so that the driving button 142 moves towards the first locking part 141, the driving button 142 pushes the first locking part 141 to retract into the machine body 1, the first locking part 141 is disengaged from the second locking part 3a, the cleaning device 3 is unlocked from the machine body 1, the cleaning device 3 is lifted upwards, the driving button 142 is released, and the driving button 142 returns to the initial position. The cleaning device 3 is lifted up until the catching protrusion 35 on the cleaning device 3 is completely separated from the catching groove 1c on the machine body 1, at which time the cleaning device 3 is separated from the machine body 1.

It should be noted that the above connection point between the cleaning device 3 and the machine body 1 may include a location point of the above latch assembly on the machine body 1; alternatively, the connection point between the cleaning device 3 and the machine body 1 may also include a location point of the latch assembly on the machine body 1 and a location point of the positioning structure on the machine body 1.

Wherein the first connection point and the second connection point are both located at the upper part of the machine body 1 and are disposed adjacent to each other. Therefore, by arranging the first connecting point and the second connecting point at the upper part of the machine body 1, the user does not need to bend down to operate when unlocking or locking the cleaning device 3 and the handle 2, and the use comfort of the user is improved. In addition, the first connecting point and the second connecting point are arranged adjacent to each other, so that a user can conveniently operate the lock catch assembly and the locking assembly in the same posture state, for example, when the lock catch assembly and the locking assembly are operated, the upper limbs of the human body do not need to move greatly, and the operation comfort level of the wet and dry dual-purpose dust collector 100 is further improved.

In some alternative embodiments of the invention, the latch assembly and the latch assembly are located on opposite sides of the body 1 (e.g., the latch assembly and the latch assembly may be located on the left and right sides of the body 1) and are both located on the side walls of the body 1. Therefore, the position space on the side wall of the machine body 1 can be fully utilized, so that the structural layout of the whole machine is reasonable, and the operation of a user is convenient.

Alternatively, the lock catch assembly and the lock catch assembly are spaced apart from each other in the up-down direction by a distance not exceeding the maximum dimension of the machine body 1 in the horizontal direction. Therefore, the operation of a user is further facilitated, and the user does not need to move the upper limb to a large distance to operate the lock catch assembly and the locking assembly respectively.

Optionally, the horizontal centerline of the latch assembly and the horizontal centerline of the locking assembly are on the same horizontal plane. Therefore, the lock catch assembly and the locking assembly are located at the same height, so that a user can operate the lock catch assembly and the locking assembly more conveniently.

In some alternative embodiments of the present invention, referring to fig. 6, 7, 12 and 13, the latch assembly and the locking assembly are both located at the top end of the body 1. Therefore, the user can find the lock catch assembly and the locking assembly conveniently, and the user can use the lock catch assembly and the locking assembly without bending down.

Further, referring to fig. 18, 19 and 29, the upper end surface of the recess portion 1d is formed in a stepped shape, the installation notch 4b is formed in the outer peripheral wall of the sewage tank 4, the installation notch 4b penetrates the bottom surface of the sewage tank 4 downward, the lower end surface of the installation notch 4b is formed in a stepped shape to be fitted to the upper end surface of the recess portion 1d, and the upper end surface of the recess portion 1d abuts against the lower end surface of the installation notch 4 b. Thereby, the contact area between the sewage tank 4 and the machine body 1 can be increased, and at the same time, the sewage tank 4 can be prevented from rotating in the horizontal direction.

For example, in the examples of fig. 18, 19 and 29, the upper end face of the recess portion 1d is formed in a stepped shape, the upper end face of the recess portion 1d includes a first end face 11d adjacent to the center of the body 1, a second end face 12d distant from the center of the body 1, the first end face 11d and the second end face 12d each have a semicircular arc shape in extension, the first end face 11d is disposed higher than the second end face 12d, and a first step face 13d extending in the vertical direction is provided between the first end face 11d and the second end face 12 d. The lower end surface of the mounting notch 4b is formed in a stepped shape to be matched with the upper end surface of the concave portion 1d, the lower end surface of the mounting notch 4b comprises a third end surface 41b adjacent to the center of the machine body 1 and a fourth end surface 42b far away from the center of the machine body 1, the extending shapes of the third end surface 41b and the fourth end surface 42b are semicircular, the third end surface 41b is higher than the fourth end surface 42b, and a second step surface 43b extending in the vertical direction is arranged between the third end surface 41b and the fourth end surface 42 b. When the sewage tank 4 is mounted on the machine body 1, the lower end of the sewage tank 4 is accommodated in the concave part 1d, the third end face 41b of the mounting notch 4b is abutted against the first end face 11d of the concave part 1d, and the fourth end face 42b of the mounting notch 4b is abutted against the second end face 12d of the concave part 1d, so that the supporting function of the sewage tank 4 is achieved; the second step surface 43b of the installation recess 4b abuts against the first step surface 13d of the recess 1d, thereby preventing the sewage tank 4 from rotating.

From this, the air current that gets into in the dust absorption chamber 81a flows through second intercommunication mouth 1e and first intercommunication mouth 4c and gets into in the sewage case 4, through set up connecting protrusion 13 on the diapire of depressed part 1d and make this connecting protrusion 13 cooperate in first intercommunication mouth 4c, made things convenient for the intercommunication of sewage case 4 and dust absorption chamber 81a, and made things convenient for the bottom of sewage case 4 to be connected with the cooperation of organism 1, also made things convenient for the dismouting of sewage case 4 simultaneously.

In some embodiments of the present invention, referring to fig. 6, 8, 12, and 21-24, a handle 48 is rotatably connected to an upper portion of the sewage tank 4, the handle 48 is received in the sewage tank 4 when in a horizontal position and the locking assembly locks the sewage tank 4, and the handle 48 is pressed against the locking assembly to unlock the sewage tank 4 after the handle 48 is rotated up to a predetermined angle (e.g., the handle 48 is rotated up to 90 degrees). Thus, by rotatably providing the handle 48 at the upper portion of the sewage tank 4, the movement of the handle 48 is made simple, and the switching of the handle 48 between the locking position and the unlocking position is achieved by rotating the handle 48, so that the locking and unlocking of the sewage tank 4 can be conveniently achieved. When the handle 48 is in the locking position, the handle 48 is in the horizontal position and is accommodated in the sewage tank 4, so that when the sewage tank 4 is mounted and locked on the machine body 1, the handle 48 is in the accommodated state, and the whole machine is compact in structure, and neat and attractive in appearance. After the handle 48 is rotated up to a preset angle, the sewage tank 4 is unlocked and separated from the machine body 1, and the sewage tank 4 can be conveniently removed from the machine body 1 by the handle 48.

Alternatively, referring to fig. 6, 8 and 12, a handle 48 is provided at the top end of the sewage tank 4, and the handle 48 is accommodated at the top of the sewage tank 4 and adjacent to the outer peripheral edge of the sewage tank 4 when in the horizontal position. Therefore, the space at the top of the sewage tank 4 can be fully utilized to store the handle 48, so that the structure of the whole machine is more compact, and interference influence and the like on other parts can be avoided.

For example, in the examples of fig. 6, 8 and 12, the top of the sewage tank 4 is formed with two arc-shaped abutting walls 45, the two arc-shaped abutting walls 45 are located along the periphery of the sewage tank 4 and are disposed radially opposite and spaced apart, each abutting wall 45 extends along the periphery of the sewage tank 4, and two receiving notches 45a are defined between the two abutting walls 45. The two handles 48 are respectively and rotatably arranged in the two receiving notches 45a, and the connection point of each handle 48 and the sewage tank 4 is positioned on the abutting wall 45.

When the sewage tank 4 is required to be mounted on the machine body 1, the handle 48 is rotated to a horizontal position, at this time, the handle 48 is accommodated in the corresponding accommodating notch 45a, at this time, the upper end surface of the handle 48 and the upper end surface of the abutting wall 45 may be located substantially in the same horizontal plane, at this time, the two handles 48 and the two abutting walls 45 may form an annular abutting wall. At the same time, the handle 48 is coupled to the locking assembly, which locks the tank 4 to the housing 1, such that the bottom surface of the cleaning device 3 can abut against the annular abutment wall. When the sewage tank 4 needs to be detached from the machine body 1, the handle 48 is rotated upward to a predetermined position (for example, the handle 48 can be rotated to a vertical position), the handle 48 is separated from the accommodating notch 45a, the sewage tank 4 is unlocked and separated from the machine body 1, and the sewage tank 4 can be conveniently removed from the machine body 1 by carrying the handle 48.

In some embodiments of the present invention, referring to fig. 21-24, the locking assembly may include: a bolt 46, a locking groove 1g adapted to cooperate with the bolt 46, and a locking spring 47. The latch 46 is horizontally movably provided on the sewage tank 4 (for example, the latch 46 is provided on the sewage tank 4 to be movable back and forth), and the latch groove 1g is formed on the body 1 (for example, the latch groove 1g is formed on the front side wall of the body 1). When the lock tongue 46 is matched in the lock groove 1g, the sewage tank 4 is in a locking state; when the lock tongue 46 is disengaged from the lock groove 1g, the sewage tank 4 is in the unlocked state. One end of the locking spring 47 is connected with the sewage tank 4, the other end of the locking spring is connected with the lock tongue 46, and when the handle 48 rotates to the unlocking position, the handle 48 is matched with the lock tongue 46 to drive the lock tongue 46 to be disengaged from the locking groove 1 g; when the handle 48 is rotated to the locking position, the handle 48 is disengaged from the lock tongue 46 and the lock spring 47 drives the lock tongue 46 to engage with the lock groove 1 g. Therefore, the locking assembly is simple in structure and convenient to operate.

For example, when the sewage tank 4 is detached from the machine body 1 (refer to e2 direction in fig. 25 as the detaching direction of the sewage tank 4), the handle 48 is rotated to the unlock position, and at this time, the handle 48 cooperates with the lock tongue 46 to drive the lock tongue 46 to move away from the lock groove 1g (for example, the handle 48 cooperates with the lock tongue 46 to drive the lock tongue 46 to move forward), so that the lock tongue 46 is disengaged from the lock groove 1g, and at this time, the sewage tank 4 is unlocked, and the sewage tank 4 can be detached from the machine body 1. When the sewage tank 4 is mounted on the machine body 1, the handle 48 is rotated to the locking position, and the locking spring 47 drives the lock tongue 46 to move toward the lock groove 1g (for example, the locking spring 47 drives the lock tongue 46 to move backward), so that the lock tongue 46 protrudes into the lock groove 1g, and the sewage tank 4 is locked on the machine body 1.

Further, referring to fig. 21 to 24, an unlocking protrusion 481 is formed on the handle 48, and the unlocking protrusion 481 may be formed at an end of the handle 48 adjacent to the lock tongue 46, the lock tongue 46 having an engagement slope 461 engaged with the unlocking protrusion 481, the engagement slope 461 extending obliquely downward in the protruding direction (e.g., in the front-to-rear direction) of the lock tongue 46. Thus, when the handle 48 is rotated to the unlock position, the unlock projection 481 on the handle 48 abuts on the engagement slope 461 of the latch 46, and at this time, the handle 48 has a driving force for the latch 46 in a direction away from the lock groove 1g (for example, the handle 48 has a forward driving force for the latch 46), and the handle 48 drives the latch 46 to move in a direction away from the lock groove 1g (for example, the handle 48 drives the latch 46 to move forward), so that the latch 46 is disengaged from the lock groove 1g, whereby the sewage tank 4 can be unlocked. When the handle 48 is rotated to the locking position, the unlocking protrusion 481 on the handle 48 is disengaged from the engagement inclined surface 461 on the latch 46, the driving force of the handle 48 to the latch 46 disappears, and the latch 46 moves toward the lock groove 1g under the driving of the locking spring 47 (for example, the latch 46 moves toward the rear under the driving of the locking spring 47), so that the latch 46 extends into the lock groove 1g, and the sewage tank 4 is locked.

According to some embodiments of the present invention, referring to fig. 6, 8 and 12, the locking assemblies include two and are disposed at intervals in a horizontal direction (e.g., the locking assemblies include two and are disposed at intervals in a left-right direction), and the handles 48 are two and correspond one-to-one to the two locking assemblies, respectively, each of the locking assemblies being interlocked with the corresponding handle 48, i.e., each of the locking assemblies being responsive to movement of the corresponding handle 48. When the sewage tank 4 is locked, both handles 48 are moved to the locking position at the same time; when the sewage tank 4 is unlocked, both handles 48 are moved to the unlocked position at the same time. By arranging two handles 48 and two corresponding locking assemblies, the sewage tank 4 can be locked on the machine body 1 more reliably, and the disassembly and assembly process of the sewage tank 4 is easier and more labor-saving by the two handles 48.

In some embodiments of the present invention, the wet and dry dual purpose vacuum cleaner 100 further comprises: and a connecting member horizontally movably provided to the sewage tank 4, to which the handle 48 is rotatably connected, the handle 48 being switched between a locking position and an unlocking position by horizontal movement of the connecting member. For example, when it is desired to lock the sewage tank 4 to the machine body 1, the handle 48 is rotated to a position suitable for carrying, the sewage tank 4 is mounted to the machine body 1, the connector is moved horizontally to the first position at this time, the handle 48 is moved to the locking position along with the connector while the connector is moved, the locking assembly is responsive to the movement of the handle 48 to lock the sewage tank 4, and the handle 48 can be rotated to the storage position by rotating the handle 48. When the sewage tank 4 needs to be detached from the machine body 1, the connecting piece is horizontally moved to the second position, the handle 48 moves to the unlocking position along with the connecting piece when the connecting piece moves, the locking assembly responds to the movement of the handle 48 to unlock the sewage tank 4, the handle 48 is rotated to a position suitable for carrying, and the sewage tank 4 is removed from the machine body 1. Therefore, the locking and unlocking operations of the sewage tank 4 can be simple, and the use experience of a user is improved.

In some embodiments of the present invention, the wet and dry dual purpose vacuum cleaner 100 further comprises: the connecting piece is arranged on the sewage tank 4 in a vertically movable mode, the handle 48 is rotatably connected to the connecting piece, and the handle 48 is switched between the locking position and the unlocking position through the vertical movement of the connecting piece and the rotation of the handle 48. For example, when the sewage tank 4 needs to be mounted and locked on the machine body 1, the handle 48 is rotated to a position suitable for carrying, the sewage tank 4 is mounted on the machine body 1, the connecting piece is moved to the third position in the vertical direction, the handle 48 moves along with the connecting piece while the connecting piece moves, after the connecting piece moves to the third position, the handle 48 is rotated to enable the handle 48 to rotate to the locking position, and the locking assembly is used for locking the sewage tank 4 in response to the movement of the handle 48. When the sewage tank 4 needs to be detached from the machine body 1, the handle 48 is rotated to enable the handle 48 to leave the locking position, the connecting piece is moved to the fourth position along the up-down direction, the handle 48 moves along with the connecting piece when the connecting piece moves, and after the connecting piece moves to the fourth position, the locking assembly responds to the movement of the handle 48 to unlock the sewage tank 4, and at the moment, the sewage tank 4 can be removed from the machine body 1. Therefore, the operation processes of locking and unlocking the sewage tank 4 can be more diversified, and the use experience of a user is improved.

When the sewage tank 4 and the cleaning device 3 are mounted on the machine body 1, the sewage tank 4 may be mounted on the machine body 1, and then the cleaning device 3 may be mounted on the machine body 1 and engaged with the sewage tank 4. When the sewage tank 4 is detached from the machine body 1, the cleaning device 3 may be detached from the machine body 1, and then the sewage tank 4 may be detached from the machine body 1.

According to some embodiments of the present invention, referring to fig. 25, 26 and 30, a mounting groove 1f adapted to accommodate the cleaning liquid tank 5 is formed on the body 1, and at least a portion of the cleaning liquid tank 5 is located in the mounting groove 1 f. Therefore, the contact area between the cleaning liquid tank 5 and the machine body 1 can be increased, the cleaning liquid tank 5 can be reliably installed on the machine body 1, and the size of the whole machine in the horizontal direction can be reduced, so that the whole machine can be moved flexibly, and the use is more convenient. For example, it is possible that a part of the cleaning liquid tank 5 is located inside the installation groove 1f and another part is located outside the machine body 1; alternatively, it may be that the entire cleaning liquid tank 5 is located in the mounting groove 1f, and the surface of the cleaning liquid tank 5 away from the center of the body 1 may be flush with the corresponding surface of the body 1.

For example, in some examples of the present invention, referring to fig. 25, 26 and 30, a mounting groove 1f is formed on a rear side wall of the body 1 and opened toward the rear, a cleaning liquid tank 5 is provided at the rear side of the body 1 within the mounting groove 1f, a rear surface of the cleaning liquid tank 5 may protrude rearward beyond the opened mouth, or a rear surface of the cleaning liquid tank 5 may be located within the opened mouth, or a rear surface of the cleaning liquid tank 5 may be flush with an edge of the opened mouth.

Alternatively, referring to fig. 25 to 27, the cleaning liquid tank 5 is detachably provided in the installation groove 1f, a top wall of the installation groove 1f (the top wall of the installation groove 1f refers to an upper side wall of the installation groove 1 f) has a first installation guide surface 11f, an upper end surface of the cleaning liquid tank 5 has a second installation guide surface 51 mated with the first installation guide surface 11f, and both the first installation guide surface 11f and the second installation guide surface 51 extend obliquely downward in a back-to-front direction. Thus, when the cleaning liquid tank 5 is mounted in the mounting groove 1f, the cleaning liquid tank 5 can be quickly mounted in place by the guiding action by the mutual cooperation of the first mounting guide surface 11f and the second mounting guide surface 51, and the effect of saving labor can be achieved.

According to some embodiments of the present invention, referring to fig. 25 to 27, the cleaning solution tank 5 is detachably provided to the machine body 1, and the cleaner includes a locking assembly for locking the cleaning solution tank 5 to the machine body 1, the locking assembly including a locking buckle 161 and a locking groove 5b which are engaged with each other, one of the locking buckle 161 and the locking groove 5b being provided to the machine body 1 and the other being provided to the cleaning solution tank 5. For example, when the lock catch 161 is provided on the machine body 1, the lock groove 5b is provided on the cleaning liquid tank 5; when the lock catch 161 is provided on the cleaning liquid tank 5, the lock groove 5b is provided on the machine body 1. When the locking buckle 161 is matched in the locking groove 5b, the cleaning solution tank 5 is in a locking state, and the cleaning solution tank 5 is locked on the machine body 1; when the locking buckle 161 is disengaged from the locking groove 5b, the cleaning liquid tank 5 is in an unlocked state, and the cleaning liquid tank 5 can be separated from the machine body 1.

Thus, when the cleaning liquid tank 5 needs to be detached from the machine body 1, the locking buckle 161 is disengaged from the locking groove 5b, so that the cleaning liquid tank 5 can be unlocked; when the cleaning liquid tank 5 is required to be mounted on the machine body 1, the locking buckle 161 is fitted into the locking groove 5b, so that the cleaning liquid tank 5 can be locked on the machine body 1. Through the locking component that sets up, can conveniently lock cleaning solution case 5 on organism 1, also make things convenient for the dismouting and the washing of cleaning solution case 5 simultaneously.

Alternatively, referring to fig. 27, a locking buckle 161 is provided on the body 1 to be movable up and down and a locking groove 5b is formed on the cleaning liquid tank 5, and the locking assembly further includes: an unlock button 162 and a lock spring. An unlocking button 162 is movably provided on the machine body 1 back and forth, the unlocking button 162 is adapted to cooperate with the locking buckle 161 to drive the locking buckle 161 to disengage from the locking groove 5b, one end of the locking spring is connected with the machine body 1 and the other end is connected with the locking buckle 161, and the locking spring is adapted to drive the locking buckle 161 to cooperate with the locking groove 5 b. Thus, when the cleaning liquid tank 5 needs to be detached from the machine body 1, the unlocking button 162 is pressed so that the unlocking button 162 pushes the lock catch 161 to move in a direction away from the lock groove 5b, thereby disengaging the lock catch 161 from the lock groove 5b, and thus the cleaning liquid tank 5 can be unlocked. When the cleaning solution tank 5 is required to be mounted on the machine body 1, the locking buckle 161 moves towards the locking groove 5b under the action of the elastic force of the locking spring, so that the locking buckle 161 is matched into the locking groove 5b, the cleaning solution tank 5 can be locked on the machine body 1, and the locking and unlocking operations of the cleaning solution tank 5 are more convenient.

Further, referring to fig. 27, the unlocking button 162 has a first driving inclined surface 1621, the locking buckle 161 has a second driving inclined surface 1611 engaged with the first driving inclined surface 1621, and both the first driving inclined surface 1621 and the second driving inclined surface 1611 extend obliquely toward the front in the extending direction (e.g., in the top-to-bottom direction) of the locking buckle 161. Thus, when the unlocking button 162 is pressed, the unlocking button 162 has a driving force to the locking buckle 161 toward a direction away from the locking groove 5b (for example, the unlocking button 162 has an upward driving force to the locking buckle 161) by the engagement of the first driving inclined surface 1621 of the unlocking button 162 and the second driving inclined surface 1611 of the locking buckle 161, and the locking buckle 161 can be conveniently driven to move in a direction away from the locking groove 5b (for example, the unlocking button 162 drives the locking buckle 161 to move upward), whereby the locking buckle 161 can be disengaged from the locking groove 5 b.

For example, in the example of fig. 25 to 27, a mounting groove 1f is formed on the rear side wall of the body 1, the mounting groove 1f is opened rearward, the cleaning liquid tank 5 is adapted to be accommodated in the mounting groove 1f, and the cleaning liquid tank 5 is locked to the body 1 by the above-described locking assembly. The locking assembly comprises the locking buckle 161, the locking groove 5b, the unlocking button 162 and the locking spring, wherein the locking buckle 161 is arranged on the machine body 1 in a vertically movable manner and is positioned on the top wall of the mounting groove 1f, the locking groove 5b is formed on the upper end surface of the cleaning liquid tank 5, and the unlocking button 162 is arranged on the rear side wall of the machine body 1 in a vertically movable manner and is positioned above the mounting groove 1 f.

Alternatively, in the axial direction of the roll brush 84, the illumination lamp 88 is provided adjacent to the middle of the brush housing 81. Thereby, the effective illumination range of the illumination lamp 88 can be increased.

According to some embodiments of the present invention, referring to fig. 34 to 38, the floor brush 8 includes: a brush housing 81, a roller brush assembly, a locking mechanism and a drive mechanism 86. The brush housing 81 defines a dust suction chamber 81a therein, and the brush housing 81 has a suction port 81b and a mounting port 81c communicating with the dust suction chamber 81 a. When the cleaner is in operation, solid waste such as dust on a surface to be cleaned can be sucked into the suction chamber 81a through the suction port 81 b. The roller brush assembly includes a roller brush 84 and an end cap 85, the end cap 85 is provided at one axial end of the roller brush 84 (e.g., the end cap 85 is provided at the right end of the roller brush 84), the roller brush 84 is rotatably provided in the dust suction chamber 81a, a driving mechanism 86 may be provided in the brush housing 81, and the driving mechanism 86 is used to drive the roller brush 84 to rotate. When the rolling brush 84 rotates, the rolling brush 84 can be in friction contact with the surface to be cleaned, and the cleaning and nursing effects of the surface to be cleaned can be achieved.

An end cap 85 is provided in the mounting port 81c and detachably connected to the brush housing 81, and the roller brush 84 is adapted to pass through the mounting port 81c when the roller brush assembly is detached. The locking mechanism is disposed between the end cover 85 and the brush housing 81, and when the end cover 85 rotates in a first direction (e.g., the first direction may be clockwise), the end cover 85 is locked with the brush housing 81 by the locking mechanism, and when the end cover 85 rotates in a second direction (e.g., the second direction may be counterclockwise) opposite to the first direction, the end cover 85 is unlocked from the brush housing 81. Thus, when the rolling brush assembly is mounted, the rolling brush assembly can pass through the mounting opening 81c along the axial direction (such as the left-right direction) and extend into the brush housing 81 until the end cover 85 of the rolling brush assembly is positioned at the mounting opening 81c, at this time, the end cover 85 can be rotated along the first direction, and when the end cover 85 is rotated along the first direction to the first set position, the end cover 85 is in locking connection with the brush housing 81 through the locking mechanism. When the roller brush assembly is taken out of the brush housing 81, the end cover 85 can be rotated in the second direction, and when the end cover 85 is rotated in the second direction to the second set position, the end cover 85 and the brush housing 81 are unlocked, and the roller brush assembly is pulled out of the mounting opening 81c in the axial direction. Therefore, the roller brush 84 can be assembled and disassembled simply and the replacement operation is more convenient.

Through set up the mounting port 81c on the brush shell 81 of the floor brush 8 and set up be suitable for with this mounting port 81c complex end cover 85 in the axial one end of round brush 84, when changing round brush 84, can install round brush 84 to brush shell 81 or take out in the brush shell 81 through this mounting port 81c, realize the side-mounting and the taking out of round brush 84 to through the locking mechanism who sets up, when end cover 85 rotates along different directions, can realize the locking connection between end cover 85 and the brush shell 81 or break away from the locking, make the change operation of round brush 84 more convenient.

Alternatively, the rotation direction of the roll brush 84 may be the first direction. Therefore, the rotation direction of the rolling brush 84 is consistent with the rotation direction of the end cover 85 during locking, so that the rolling brush assembly can be locked with the brush housing 81 more when the wet and dry dual-purpose dust collector 100 works, and the rolling brush assembly is prevented from loosening during working.

According to some alternative embodiments of the present invention, referring to fig. 35-37, the roller brush 84 has a drive end 841 (e.g., the left end of the roller brush 84) and a non-drive end (e.g., the right end of the roller brush 84), the drive end 841 being removably engaged with the drive mechanism 86 via a spline 8711, the non-drive end being coupled to the end cap 85. Thus, the driving end 841 of the roller brush 84 is connected with the driving mechanism 86 through the spline 8711, so that the roller brush 84 can be reliably connected with the driving mechanism 86.

For example, in the example of fig. 35 and 36, the driving mechanism 86 may be a motor, and the driving mechanism 86 may be provided at the rear side of the roller brush 84, and the floor brush 8 further includes: a transmission mechanism for transmitting the driving force of the driving mechanism 86 to the roller brush 84 may be provided on one axial side of the roller brush 84 (for example, the transmission mechanism may be provided on the left side of the roller brush 84) and adjacent to the driving end 841 of the roller brush 84. The transmission mechanism may include: the driving end 841 of the rolling brush 84 is detachably connected with the driving end 871 of the rolling brush through a spline 8711. Further, a housing cover 872 for housing the transmission mechanism may be provided in the brush housing 81, so that dirt such as dust can be prevented from entering the transmission mechanism to affect the operation of the floor brush 8.

According to some alternative embodiments of the present invention, referring to fig. 37, the locking mechanism includes a limit groove 85a and a limit block 82 that are engaged with each other, one of the end cover 85 and the brush housing 81 is provided with the limit groove 85a and the other is provided with the limit block 82 engaged with the limit groove 85a. For example, when the end cover 85 is provided with a limit groove 85a, the brush housing 81 is provided with a limit block 82; when the end cover 85 is provided with the limiting block 82, the brush housing 81 is provided with the limiting groove 85a. Thus, the end cover 85 can be locked on the brush housing 81 by the cooperation of the limit groove 85a and the limit block 82; when the limiting block 82 is disengaged from the limiting groove 85a, the end cover 85 is disengaged from the brush housing 81. Wherein, the circumferential one end of the limit groove 85a is opened, when the end cover 85 rotates along the first direction, the limit block 82 is screwed into the limit groove 85a from the open end of the limit groove 85a, and by rotating the end cover 85 along the first direction, the cooperation between the limit block 82 and the limit groove 85a can be conveniently realized. When the end cover 85 rotates in the second direction, the stopper 82 is screwed out from the open end of the limit groove 85a, so that the separation between the stopper 82 and the limit groove 85a can be conveniently realized.

Alternatively, referring to fig. 37, a stopper groove 85a is provided on the end cover 85, and a stopper 82 is provided on the inner peripheral wall of the mounting port 81 c. Thus, by rotating the end cover 85, the stopper 82 in the mounting port 81c can be conveniently engaged with or disengaged from the stopper groove 85a on the end cover 85.

In some embodiments of the present invention, referring to fig. 37, the limit groove 85a has opposite first and second ends in the circumferential direction of the mounting port 81c, the first end of the limit groove 85a being open and the second end of the limit groove 85a being closed. Thus, when the rolling brush assembly is mounted in the brush housing 81, the end cover 85 is rotated in the first direction, the limiting block 82 is screwed into the limiting groove 85a from the first end of the limiting groove 85a, and the second end of the limiting groove 85a is closed, so that the rotation angle of the end cover 85 can be limited, when the limiting block 82 is screwed into the limiting groove 85a to be abutted against the second end of the limiting groove 85a, the end cover 85 cannot continue to rotate, and at the moment, the end cover 85 is indicated to rotate in place, and the rolling brush assembly is locked on the brush housing 81.

Alternatively, referring to fig. 37, in the radial direction of the end cap 85, one end of the limit groove 85a, which is far from the center of the end cap 85, is opened. Thereby, the process of fitting and removing the stopper 82 and the stopper groove 85a is made easier to operate.

Further, referring to fig. 37, a positioning notch 82a is formed on the stopper 82, and a positioning protrusion 851 is formed on the inner sidewall of the stopper groove 85a to be engaged with the positioning notch 82 a. Therefore, after the limiting block 82 is screwed into the limiting groove 85a, the reliable connection and locking between the rolling brush assembly and the brush shell 81 can be further ensured through the matching of the positioning convex blocks 851 in the limiting groove 85a and the positioning notch 82a on the limiting block 82.

Alternatively, referring to fig. 37, the plurality of limit grooves 85a are provided in plurality (for example, three) and at intervals in the circumferential direction of the end cover 85, the plurality of limit grooves 85a may be provided at uniform intervals in the circumferential direction of the end cover 85, and the open ends of each limit groove 85a are located at the same end in the circumferential direction of the limit groove 85 a; the limiting blocks 82 are multiple (for example, three) and are arranged at intervals along the circumferential direction of the mounting opening 81c, the limiting blocks 82 can be arranged at intervals uniformly along the circumferential direction of the mounting opening 81c, and the number of the limiting blocks 82 is the same as that of the limiting grooves 85a and corresponds to one limiting block. Thus, when the end cover 85 is rotated in the first direction during installation of the rolling brush assembly, the plurality of limiting blocks 82 are simultaneously screwed into the corresponding limiting grooves 85 a; when the roller brush assembly needs to be taken out, the end cover 85 is rotated in the second direction, and the plurality of limiting blocks 82 are simultaneously screwed out of the corresponding limiting grooves 85 a. Through the cooperation of a plurality of stopper 82 and a plurality of spacing groove 85a that set up, can further make the round brush subassembly reliably lock on brush shell 81, and can guarantee that round brush 84 atress is comparatively even in circumference direction.

According to some embodiments of the present invention, the roll brush 84 includes a roll brush body and bristles, including hard bristles and nap, provided on the roll brush body. Thus, the cleaning effect can be improved by the combined action of the hard bristles and the fluff. Alternatively, the bristles may be integrally fixed to an adhesive body, which may be adhered to the roll brush body (for example, the adhesive body may be lint with an adhesive layer, and the adhesive body may be coated on the outer circumferential surface of the roll brush body). Alternatively, the bristles may be directly secured to the roll brush body.

The duct structure of the wet and dry dual-purpose vacuum cleaner 100 of the present invention is described below.

Referring to fig. 35 to 44 (the arrow direction in fig. 40 to 42 is the flow direction of the air flow), the duct structure of the wet and dry dual-purpose vacuum cleaner 100 of the present invention includes: a floor brush 8, a sewage recovery assembly and a cleaning device 3.

Specifically, referring to fig. 38 and 39, the floor brush 8 defines a suction chamber 81a therein, and the floor brush 8 has a suction port 81b communicating with the suction chamber 81a, and dirt such as dust on a surface to be cleaned can be sucked into the suction chamber 81a through the suction port 81 b. The sewage recovery assembly includes a sewage tank 4 in communication with the dust suction chamber 81a, the sewage tank 4 being provided above the floor brush 8 and for recovering sewage, the sewage tank 4 having an air outlet 4a. The air flow enters the dust collection cavity 81a through the suction inlet 81b and flows upwards into the sewage tank 4, sewage carried in the air flow can be collected in the sewage tank 4, and secondary pollution caused by the fact that the sewage in the air flow is sucked into the power assembly 32 can be avoided.

Referring to fig. 40 to 43, the cleaning apparatus 3 is located above the sewage tank 4, the cleaning apparatus 3 includes a dust drum assembly 31 for dust-gas separation and a power assembly 32, the dust drum assembly 31 is used for dust-gas separation and recycling solid garbage such as separated dust in the dust drum assembly 31, the power assembly 32 provides power for the flow of air flow, and the dust drum assembly 31 has an air inlet 311a communicating with the air outlet 4 a. Under the action of the power assembly 32, air flows continuously upwards through the sewage tank 4 and the dust barrel assembly 31 after entering the dust collection cavity 81a through the suction inlet 81b, the air flows through the sewage tank 4, flows out of the sewage tank 4 through the air outlet 4a and upwards flows, enters the dust barrel assembly 31 through the air inlet 311a to carry out dust-air separation, and solid wastes such as dust separated from the air flow are collected in the dust barrel assembly 31, and relatively clean air flow after dust-air separation through the dust barrel assembly 31 can be discharged to the external environment through the air outlet 321c on the peripheral wall of the power assembly 32.

Alternatively, the dustcup assembly 31 may include the dustcup 311 and a cyclone 313 or a filter provided in the dustcup 311, the cyclone 313 may be a single stage cyclone or a multi-stage cyclone, and the filter may be a hepa filter. Specifically, when the dust barrel assembly 31 includes the dust barrel 311 and the cyclone 313 provided in the dust barrel 311, the cyclone 313 may perform dust-gas separation on the air flow entering the dust barrel 311, and when the cyclone 313 is a single stage cyclone, may perform single stage dust-gas separation on the air flow entering the dust barrel 311; when the cyclone 313 is a multi-stage cyclone, the air flow entering the dust drum 311 can be subjected to multi-stage dust-gas separation, and the dust-gas separation effect can be further improved. When the dust cartridge assembly 31 includes the dust cartridge 311 and a filter provided in the dust cartridge 311, the filter may filter the air flow entering the dust cartridge 311 to separate dust and air, and the filter may be a hepa filter, thereby ensuring a filtering effect of the filter.

According to the air duct structure of the wet and dry dual-purpose dust collector 100, the sewage tank 4 is arranged above the floor brush 8, and the cleaning device 3 is arranged above the sewage tank 4, so that when the wet and dry dual-purpose dust collector 100 works, under the action of the power component 32, air flow enters the dust collection cavity 81a from the suction inlet 81b and continuously flows upwards through the sewage tank 4 and the dust barrel component 31, the flow path of the air flow can be shortened, the loss of the air flow is reduced, and sewage carried in the air flow is collected in the sewage tank 4 in the process of flowing through the sewage tank 4, so that secondary pollution caused by the fact that the sewage carried by the air flow is sucked into the power component 32 can be avoided.

According to some embodiments of the present invention, referring to fig. 40 and 41, the bottom of the dustcup assembly 31 has the air inlet 311a, the top of the sewage tank 4 has the air outlet 4a, and the flow path of the air flow from the sewage tank 4 into the dustcup assembly 31 extends along the center line of the sewage tank 4 or the center line of the dustcup assembly 31, thereby further shortening the flow path of the air flow and further reducing the air flow loss. The center line of the sewage tank 4 refers to the center line of the sewage tank 4 in the vertical direction, and the center line of the dustcup assembly 31 refers to the center line of the dustcup assembly 31 in the vertical direction.

Wherein the flow path of the air flow from the sewage tank 4 into the dustcup assembly 31 extends along the centerline of the sewage tank 4 or the centerline of the dustcup assembly 31, may include the following: 1) When the center line of the sewage tank 4 and the center line of the dust barrel assembly 31 coincide, the flow path of the air flow from the sewage tank 4 into the dust barrel assembly 31 extends along both the center line of the sewage tank 4 and the center line of the dust barrel assembly 31; 2) When the center line of the sewage tank 4 and the center line of the dustcup assembly 31 deviate from each other, a flow path from the sewage tank 4 into the dustcup assembly 31 may extend along the center line of the sewage tank 4; 3) When the center line of the sewage tank 4 and the center line of the dustcup assembly 31 are deviated from each other, a flow path from the sewage tank 4 into the dustcup assembly 31 may extend along the center line of the dustcup assembly 31.

According to some alternative embodiments of the present invention, referring to fig. 40 and 41, the bottom of the dustcup assembly 31 has an air inlet 311a, an air inlet pipe 312 is connected to the air inlet 311a, the air inlet pipe 312 may extend in a vertical direction, the top of the sewage tank 4 has an air outlet 4a, and the air inlet pipe 312 communicates with the air outlet 4 a. Thus, the air flow in the sewage tank 4 flows out through the air outlet 4a at the top of the sewage tank 4 and flows into the dust barrel assembly 31 through the air inlet 311a of the dust barrel assembly 31 in the process of flowing from the sewage tank 4 to the dust barrel assembly 31, so that the air flow can flow along the direction adjacent to the central line of the sewage tank 4 or the dust barrel assembly 31 in the process of flowing from the sewage tank 4 to the dust barrel assembly 31, and the flow loss of the air flow is reduced. In addition, the air inlet pipe 312 is connected to the air inlet 311a, so that the dust barrel assembly 31 and the sewage tank 4 can be conveniently connected, and the cleaning device 3 can be used independently and flexibly.

For example, in the examples of fig. 40 and 41, the center line of the dustcup assembly 31 and the center line of the sewage tank 4 both extend in the vertical direction and overlap, the bottom of the dustcup assembly 31 has the air inlet 311a and the center line of the air inlet 311a coincides with the center line of the dustcup assembly 31. The air inlet 311a is connected with an air inlet pipe 312, the air inlet pipe 312 extends along the vertical direction, the top of the sewage tank 4 is provided with an air outlet 4a, the central line of the air outlet 4a coincides with the central line of the sewage tank 4, and the lower end of the air inlet pipe 312 is inserted into the air outlet 4a and communicated with the air outlet 4 a. The top of the sewage tank 4 has an annular abutment wall provided around the air outlet 4a, which is located at the outer peripheral edge of the sewage tank 4, and the outer peripheral edge portion of the bottom surface of the dustcup assembly 31 abuts against the annular abutment wall on the sewage tank 4 when the cleaning device 3 is mounted on the machine body 1 and engaged with the sewage tank 4.

Therefore, the butt joint structure of the cleaning device 3 and the sewage tank 4 is simple, and the cleaning device 3 is convenient to assemble and disassemble. And, in the course of the air flow from the sewage tank 4 to the dustcup assembly 31, the air flow vertically flows upward along the center line of the dustcup assembly 31 and the center line of the sewage tank 4, so that the loss of the air flow can be reduced better. In addition, the cleaning device 3 can be limited in the circumferential direction by inserting the lower end of the air inlet pipe 312 of the dust barrel assembly 31 into the air outlet 4a of the sewage tank 4.

Further, referring to fig. 40 and 41, the air outlet 4a is connected with an air guide pipe 41, the air guide pipe 41 can extend downwards from the air outlet 4a into the inner cavity of the sewage tank 4, the air guide pipe 41 is connected with the air inlet pipe 312 and is conducted, the lower end of the air inlet pipe 312 can pass through the air outlet 4a and is inserted into the air guide pipe 41, and the connection point of the air guide pipe 41 and the air inlet pipe 312 is located between the dust barrel assembly 31 and the sewage tank 4. Thus, after the sewage carried in the air flow entering the sewage tank 4 is collected in the sewage tank 4 by the air guide duct 41 provided at the air outlet 4a, the air flow can enter the air inlet duct 312 by the guide action of the air guide duct 41, and by locating the connection point of the air guide duct 41 and the air inlet duct 312 between the dust barrel assembly 31 and the sewage tank 4, the air flow can be made to flow from the sewage tank 4 to the dust barrel assembly 31 all the time in the direction substantially adjacent to the centers of the sewage tank 4 and the dust barrel assembly 31, and the loss of the air flow can be reduced.

In some embodiments of the present invention, referring to fig. 40 and 41, at least a portion of the air guide duct 41 is located in the sewage tank 4, for example, it may be that a portion of the air guide duct 41 is located in the sewage tank 4 and another portion extends upward to the outside of the sewage tank 4, or it may be that the entire air guide duct 41 is located in the sewage tank 4 and the upper end of the air guide duct 41 extends to the air outlet 4a. Thereby, the space occupied by the air guide pipe 41 can be reduced, and the air duct structure is compact. The air duct 41 includes a first duct section 411, a second duct section 412 and a third duct section 413 sequentially connected from bottom to top, the third duct section 413 is connected to the air inlet duct 312 and concentrically arranged, the second duct section 412 and the third duct section 413 are angled to each other, and the first duct section 411 and the third duct section 413 are parallel and eccentrically arranged. Thus, by providing the air guide duct 41 with the above-described structure, the inlet end of the air guide duct 41 can be prevented from directly opposing the flow of the sewage carried in the sewage tank 4, and a part of the flow of the sewage carried in the sewage can be prevented from directly flowing upward into the air inlet duct 312 through the air guide duct 41. And, by disposing the third conduit section 413 of the air conduit 41 concentrically with the air inlet pipe 312, the air flow can be made to flow vertically upward into the air inlet pipe 312 directly after the third conduit section 413, further reducing the air flow loss.

Alternatively, referring to fig. 40 and 41, an air intake duct 42 extending in a vertical direction is provided in the sewage tank 4, a lower end of the air intake duct 42 communicates with the dust suction chamber 81a, an upper end of the air intake duct 42 communicates with an inner chamber of the sewage tank 4, the air intake duct 42 and the first duct section 411 are located on opposite sides of a center line of the third duct section 413, and an air intake hole 411a is provided on a side wall of the first duct section 411. The air flow entering the dust collection cavity 81a through the suction inlet 81b flows into the sewage tank 4 through the air inlet pipeline 42, and the sewage carried in the air flow falls into the sewage tank 4 to be collected in the process of flowing into the air inlet hole 411a on the first pipe section 411 from the air flow flowing out of the upper end of the air inlet pipeline 42, enters the air guide pipe 41 through the air inlet hole 411a, flows through the first pipe section 411, the second pipe section 412 and the third pipe section 413 of the air guide pipe 41 in sequence, and then flows into the air inlet pipe 312.

Therefore, by arranging the air inlet pipeline 42 in the sewage tank 4, the air flow in the dust collection cavity 81a can vertically flow upwards along the air inlet pipeline 42 in the process of flowing into the sewage tank 4, and flows out of the upper end of the air inlet pipeline 42 and flows into the sewage tank 4, so that the air flow is limited to flow in the air inlet pipeline 42, the air flow can be diffused, the flow speed of the air flow is increased, and the flow loss of the air flow is reduced. Also, by locating the air intake duct 42 and the first conduit section 411 on opposite sides of the center line of the third conduit section 413, it is possible to avoid the air outlet end of the air intake duct 42 being vertically opposed to or close to the air inlet 411a of the first conduit section 411, and it is possible to further prevent the air flow flowing out of the air intake duct 42 from directly flowing into the first conduit section 411, thereby reducing the sewage collection effect.

Further, referring to fig. 40 and 1, a baffle plate 43 extending in the up-down direction is provided between the air intake duct 42 and the air intake hole 411a, the baffle plate 43 being spaced apart from the air intake duct 42 and the first duct section 411 in the horizontal direction, and the lower end of the baffle plate 43 being spaced apart from the bottom wall of the sewage tank 4. Thus, by providing the flow blocking plate 43 extending in the up-down direction between the air intake duct 42 and the air intake hole 411a, the air flow carrying sewage can be further prevented from entering the air guide duct 41, and the air flow flowing out from the upper end of the air intake duct 42 flows to the flow blocking plate 43 and collides with the flow blocking plate 43 to realize gas-liquid separation in the process of flowing to the air intake hole 411a on the first duct section 411, the sewage in the air flow can flow downwards along the flow blocking plate 43 and falls into the sewage tank 4 under the guiding action of the flow blocking plate 43, and then the air flow bypasses the lower end of the flow blocking plate 43 and flows upwards and enters the air guide duct 41 through the air intake hole 411a in the first duct section 411.

According to other embodiments of the present invention, referring to fig. 42 to 44, the sidewall of the sewage tank 4 has an air outlet 4a, the sidewall of the dustcup assembly 31 has an air inlet 311a, the air inlet 311a and the air outlet 4a are connected through an air inlet pipe 312, and the air inlet pipe 312 is located outside the dustcup assembly 31 and the sewage tank 4. During the process of entering the dust barrel assembly 31 from the sewage tank 4, the air flow mainly flows along the air inlet pipe 312 positioned outside the sewage tank 4 and the dust barrel assembly 31, and the flow path of the air flow entering the dust barrel assembly 31 from the sewage tank 4 is deviated from the center line of the sewage tank 4 and the center line of the dust barrel assembly 31. Therefore, the arrangement of the flow path of the air flow is more flexible, and the arrangement of the air duct structure is more flexible and novel. The center line of the sewage tank 4 refers to the center line of the sewage tank 4 in the vertical direction, and the center line of the dustcup assembly 31 refers to the center line of the dustcup assembly 31 in the vertical direction.

In some alternative embodiments of the present invention, referring to fig. 42 to 44, a connection channel 1k having an L shape is provided in the body 1, the connection channel 1k having a first open end 11k facing the sewage tank 4 and a second open end 12k facing upward, the first open end 11k being opposite to and communicating with the air outlet 4a, and the second open end 12k being connected to the air inlet duct 312. Therefore, by arranging the L-shaped connecting channel 1k on the machine body 1, the air flow flowing out from the air outlet 4a of the sewage tank 4 flows through the L-shaped connecting channel 1k and then enters the air inlet pipe 312, and enters the dust barrel assembly 31 through the air inlet 311a on the dust barrel assembly 31 after passing through the air inlet pipe 312, thereby facilitating the connection between the air inlet pipe 312 and the air outlet 4a on the sewage tank 4 and ensuring that the whole structure is more compact and attractive.

Alternatively, referring to fig. 43 and 44, a first sealing ring 111k is provided between the first open end 11k and the end face of the air outlet 4a, and a second sealing ring 121k is provided between the second open end 12k and the end face of the air inlet duct 312. Thereby, the sealing property of the flow passage of the air flow from the sewage tank 4 to the air inlet duct 312 can be ensured.

In some alternative embodiments of the present invention, referring to fig. 42 to 44, the dust barrel assembly 31 includes a dust barrel 311 and a cyclone 313 provided in the dust barrel 311, an air inlet 311a is formed at a sidewall of the dust barrel 311, an air flow enters the dust barrel 311 through the air inlet 311a, dust and gas separation is performed through the cyclone 313, solid wastes such as separated dust are collected in the dust barrel 311, and clean air flow flows upward and is discharged to the external environment through an air outlet 321c provided at an outer circumferential wall of the power assembly 32.

Optionally, a baffle is disposed in the dust barrel 311 and spaced apart from the air inlet 311a, and at least a portion of the baffle is disposed opposite to the air inlet 311a, or a portion of the baffle is opposite to the air inlet 311a, or the whole baffle is opposite to the air inlet 311 a. Therefore, when the air flow enters the dust barrel 311 through the air inlet 311a on the side wall of the dust barrel 311, at least a part of the baffle is opposite to the air inlet 311a, and the air flow entering through the air inlet 311a collides with the baffle, so that the air flow entering the dust barrel 311 is rotated, and the dust-gas separation effect can be improved.

According to some alternative embodiments of the present invention, referring to fig. 42, an air guide duct 44 is provided in the sewage tank 4, and the air guide duct 44 includes a first duct section 441 and a second duct section 442 sequentially connected from bottom to top, the first duct section 441 extends in a vertical direction, the second duct section 442 extends in a horizontal direction, one end of the second duct section 442 is connected to the first duct section 441, and the other end is butted with the air outlet 4 a. The air flow entering the sewage tank 4 is collected in the sewage tank 4 during the flow to the air guide duct 44, and then enters the first duct section 441 through the air inlet holes 411a of the first duct section 441 during the upward flow and flows along the first duct section 441.

The air flow is then changed in direction of the horizontal direction by the guiding action of the connection portion of the first and second pipe sections 441 and 442, flows into the second pipe section 442 and flows along the second pipe section 442, and finally flows out through the air outlet 4a on the sidewall of the sewage tank 4. Thus, by providing the air guide duct 44 in the sewage tank 4, after sewage carried in the air flow entering the sewage tank 4 is collected in the sewage tank 4, the air flow can enter the air inlet duct 312 through the guiding action of the air guide duct 44, so that the air flow flowing in the vertical direction is conveniently guided to flow in the horizontal direction and flows out from the air outlet 4a on the side wall of the sewage tank 4.

According to some embodiments of the present invention, referring to fig. 38 and 39, the floor brush 8 includes a brush housing 81 and a roller brush 84, a dust suction chamber 81a is defined in the brush housing 81, a suction inlet 81b is formed at the bottom of the brush housing 81, and the suction inlet 81b may be disposed adjacent to the center of the bottom of the brush housing 81, such that the suction inlet 81b is adjacent to the center line of the sewage tank 4, further shortening the flow path of the air flow. The rolling brush 84 is rotatably provided in the dust suction chamber 81a with a part of the rolling brush 84 being located at the suction port 81b, a suction pipe 83 communicating with the inner chamber of the sewage tank 4 is provided in the dust suction chamber 81a, the suction pipe 83 is located at the rear side of the rolling brush 84 with the suction port 83a of the suction pipe 83 facing the rolling brush 84 and the suction port 81b.

By providing the suction pipe 83 in the brush housing 81, the air flow can be concentrated in the suction pipe 83, the air flow loss can be reduced, and at the same time, the suction pipe 83 is provided at the rear side of the rolling brush 84, the length of the suction pipe 83 can be shortened, and the suction pipe 83 is provided near the center line of the sewage tank 4, further the air flow loss can be reduced.

Alternatively, referring to fig. 38 and 39, an upper side wall of the suction port 83a abuts against the rolling brush 84, and a lower side wall of the suction port 83a is spaced apart from the rolling brush 84.
