Description

Technical Field

[0002] With the continuous development of science and technology, cleaning equipment suitable for different cleaning objects has emerged. Various cleaning equipment has brought great convenience to users' work, life and study, and cleaning machine is one of them.

[0003] Existing cleaning machines are mainly divided into two categories. One is a wet cleaning machine, which achieves the purpose of cleaning by spreading clean water from a clean water bucket to the bottom surface, sweeping it with a roller brush or a discharge brush, and then recovering it into a sewage bucket with a suction nozzle. The suction nozzle of a wet cleaning machine usually forms a sealed space with the ground through the front and rear rubber scrapers, and the water on the ground enters the sealed space through the gap between the scrapers and the ground; the suction nozzle of a wet cleaning machine is small and can form a large air flow speed, so that the sewage can be recovered efficiently. However, large particles are usually not removed, so there will still be large particles left on the ground after the cleaning machine. The other is a dry cleaning machine, which has a larger suction nozzle area, and its suction nozzle is connected to the roller brush. The roller brush rotates and stirs the dust on the ground, so that it is sucked from the suction nozzle. Although the suction nozzle area of ​​a dry cleaning machine is large, large particles of residual objects can be sucked in, but such a suction nozzle has a poor water absorption effect due to the large opening and the lack of a scraper to seal.

DETAILED DESCRIPTION

[0043] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0044] The first embodiment of the present application provides a cleaning assembly 100. Figure 1 is a structural exploded diagram of the cleaning assembly 100 provided in the first embodiment of the present application; Figure 2 and Figure 3 It is a schematic diagram of the structure of the cleaning component 100 provided in the first embodiment of the present application.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the cleaning assembly 100 provided in this embodiment includes: a housing 1, a roller brush assembly 2, a cleaning air duct 3, a water spray assembly 5, a roller assembly 6, a scraper assembly 4, and an assembly component 7. Among them, the housing 1 includes a base 11 and an upper cover 12, and the upper cover 12 includes a surface cover 13, a suction nozzle front cover 14, and a suction nozzle rear cover 15; the roller brush assembly 2 includes a roller brush 21, a roller brush motor 22, a roller brush motor cover 23, and a roller brush cavity shell 24; the water spray assembly 5 includes an electromagnetic pump 51, a water pump pipe 52, a water spray component 53, and a water spray cover plate 54; the assembly component 7 includes a screw 71 and a limit piece 72, etc.

[0046] The assembly relationship of the above components is that the roller brush assembly 2 is clamped in the housing 1, specifically, as shown in FIG. Figure 2As shown, with the arrow pointing to the direction of advance, the nozzle front cover 14 is arranged at the front end of the housing 1, the face cover 13 is arranged at the rear end of the housing 1, and the nozzle rear cover 15 is arranged between the nozzle front cover 14 and the face cover 13. Since the nozzle rear cover 15, the nozzle front cover 14 and the face cover 13 are located above the housing 1, the face cover 13, the nozzle front cover 14 and the nozzle rear cover 15 are defined as a whole as an upper cover 12, so as to cooperate with the base 11 to form a complete housing 1. In particular, the nozzle front cover 14 and the nozzle rear cover 15 are both provided with a rib position 9 cavity, and there is a distance between the nozzle front cover 14 and the base 11. The roller brush 21 is arranged at the front end position of the base 11, and a part of the surface of the roller brush 21 is covered by a roller brush cavity shell 24 with an arc-shaped structure. The roller brush motor 22 is fixedly installed on the base 11 by screws 71, so that the roller brush 21 is driven to rotate by the roller brush motor 22; the cleaning air duct 3 is clamped between the roller brush cavity shell 24 and the upper cover 12, and the cleaning air duct 3 has an arc along the roller brush cavity shell 24 and an air suction port 31. The air suction port 31 is located in the cavity of the suction nozzle front cover 14, and the suction nozzle front cover 14 is arranged away from the roller brush 21 to form a suction nozzle 8 capable of absorbing dirt at the spacing between the suction nozzle front cover 14 and the base 11.

[0047] The scraper bar assembly 4 is arranged at the suction nozzle 8. Specifically, the scraper bar assembly 4 is installed on the suction nozzle front cover 14 and the suction nozzle rear cover 15. The scraper bar assembly 4 can contact the cleaned surface. During the movement of the cleaning assembly 100, due to the interaction between the scraper bar assembly 4 and the cleaned surface, the scraper bar assembly 4 can swing at the suction nozzle 8, thereby changing the suction area of ​​the suction nozzle 8.

[0048] The roller assembly 6 includes a roller 61 and a support wheel 62. The diameter of the roller 61 is much larger than the diameter of the support wheel 62. The roller 61 is installed at the rear end of the housing 1, and the support wheel 62 is installed on the side of the base 11 facing the cleaned surface. The movement of the cleaning assembly 100 is achieved through the roller assembly 6. The water spray assembly 5 is mounted in the housing 1. Since the water spray assembly 5 is not the focus of the invention of this application, it will not be explained in detail here.

[0049] The cleaning component 100 of the embodiment of the present application is to solve the problem in the prior art that a cleaning device cannot absorb liquid and large dust particles at the same time. That is, the cleaning component 100 of the embodiment of the present application can use corresponding cleaning modes to clean different types of cleaning objects (such as sewage, large particles, etc.), so that liquid and large dust particles can be absorbed by the cleaning component 100.

[0050] Specifically, the cleaning component 100 of the embodiment of the present application mainly changes the suction area of ​​the suction nozzle 8 by swinging the scraper component 4, thereby changing the cleaning mode of the suction port 31. In one possible implementation, the scraper component 4 swings through the movement of the cleaning component 100 and the action of the cleaned surface. For example, when there are large particles, the cleaning component 100 corresponds to the first moving direction, and the scraper component 4 interacts with the cleaned surface so that the scraper component 4 swings to the first position, and the scraper component 4 provides enough space to suck large particles into the clean air duct 3. At this time, the suction port 31 is in the dust suction mode; after the large particles are sucked away, the cleaning component 100 corresponds to the second moving direction, and the scraper component 4 interacts with the cleaned surface so that the scraper component 4 swings to the second position, and the scraper component 4 provides a certain gap to suck liquid into the clean air duct 3. At this time, the suction port 31 is in the water absorption mode; it should be noted that the water absorption mode is not a single absorption of water stains, it can be any kind of liquid, and it can also be fine particles.

[0051] The first moving direction of this embodiment is forward movement, and corresponding to the above, the swing of the scraper assembly 4 is based on the interaction between the scraper assembly 4 and the cleaned surface, so the scraper assembly 4 moves backward; the second moving direction of this embodiment is backward movement, so the scraper assembly 4 moves forward due to the interaction between the scraper assembly 4 and the cleaned surface. It can be seen that by reciprocating the cleaning assembly 100 along the first moving direction and the second moving direction, the suction area of ​​the suction nozzle 8 can be changed, thereby changing the cleaning mode of the suction port 31, so as to achieve the cleaning of sewage and large particles on the cleaned surface in one cleaning assembly 100.

[0052] It should be noted that the swinging of the scraper assembly 4 to the first position can be understood as the swinging of the scraper assembly 4 to the first extreme position. When the scraper assembly 4 is in the first extreme position, the angle presented by the suction nozzle 8 is the largest, that is, the suction area of ​​the suction nozzle 8 is the largest, and it can absorb large particles of dust to the maximum extent. The swinging of the scraper assembly 4 to the second position can be understood as the swinging of the scraper assembly 4 to the second extreme position. When the scraper assembly 4 is in the second extreme position, the angle presented by the suction nozzle 8 is the smallest, that is, the suction area of ​​the suction nozzle 8 is the smallest. At this time, the suction force of the suction port 31 is the largest, and the liquid or very small particles on the cleaned surface can be absorbed. It can be understood that at least one intermediate position can be provided between the first position and the second position to form a multi-stage working mode of the scraper assembly 4, that is, when the scraper assembly 4 is located at at least one intermediate position, the scraper assembly 4 changes the suction area of ​​the suction nozzle 8, and forms a general mode suitable for both dust and water absorption at the suction port 31.

[0053] Further, in this embodiment, the scraper strip assembly 4 may include the following two structures, specifically, Figures 1 to 3As shown, the first structure of the scraper assembly 4 includes a first movable scraper 41 and a second movable scraper 42. Figure 4 As shown, the first movable scraper 41 includes a connecting end 411 and a contact end 412, and a protruding structure 413 is provided at the end of the connecting end 411, and the protruding structure 413 can be pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle; the contact end 412 is the first scraper, and the first scraper is fixed to the end of the connecting end 411 away from the protruding structure 413 by rubber wrapping or gluing, and the first scraper can contact the cleaned surface; in this embodiment, the first scraper is made of soft material, and the soft material can make the first scraper better sealed when in contact with the cleaned surface, thereby making the suction effect of the suction port 31 better.

[0054] Similarly, the second movable scraper 42 includes a connecting end 421 and a contact end 422. The end of the connecting end 421 is provided with a protruding structure 423, and the protruding structure 423 can be pivotally connected to the rib position 9 in the cavity of the nozzle front cover 14 and the nozzle rear cover 15; the contact end 422 is a second scraper, and the second scraper is fixed to the end of the connecting end 421 away from the protruding structure 423 by rubber coating or gluing, and the second scraper can contact the cleaned surface; in this embodiment, the second scraper is made of soft material, and the soft material can make the second scraper better sealed when in contact with the cleaned surface, so as to make the suction effect of the air inlet 31 better. In this embodiment, the scraper assembly 4 of this structure also includes a scraper connector 45, and the scraper connector 45 is fixedly mounted on the nozzle rear cover 15 by screws 71.

[0055] In this embodiment, if Figure 2 and Figure 3 As shown, the connection end 411 of the first movable scraper strip 41 is movably connected to the shell 1 away from the roller brush 21, and the connection end 421 of the second movable scraper strip 42 is movably connected to the shell 1 close to the roller brush 21; and the contact ends 412 (422) of the two that are in contact with the cleaned surface can swing around their respective connection ends 411 (421) respectively; specifically, the protruding structure 413 of the connection end 411 of the first movable scraper strip 41 is pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle; the protruding structure 423 of the connection end 421 of the second movable scraper strip 42 is pivotally connected to the rib position 9 (not shown) in the cavity of the front cover 14 of the suction nozzle and the rear cover 15 of the suction nozzle, so that the contact ends 412 (422) of the two can swing around their respective connection ends 411 (421) within the range of the suction nozzle 8.

[0056] in, Figure 2 Schematic diagram of the state where the first scraper strip assembly 4 structure swings to the first position, specifically, Figure 2As shown, when the cleaning component 100 moves along the first moving direction, the first movable scraper bar 41 and the second movable scraper bar 42 both swing backwards, and the second movable scraper bar 42 swings to a position close to the roller brush 21, and the first movable scraper bar 41 moves away from the suction nozzle front cover 14 and fits with the second movable scraper bar 42. At this time, the gap between the first movable scraper bar 41 and the suction nozzle front cover 14 forms the suction nozzle 8, and the suction area of ​​the suction nozzle 8 becomes larger, and the air suction port 31 is in the dust suction mode, thereby absorbing large particles of dust.

[0057] Figure 3 It is a schematic diagram of the state of the first scraper assembly 4 structure swinging to the second position. When the cleaning assembly 100 moves along the second moving direction, the first movable scraper 41 and the second movable scraper 42 both swing forward, and the first movable scraper 41 and the second movable scraper 42 swing to a position away from the roller brush 21. The first movable scraper 41 fits with the suction nozzle front cover 14 away from the roller brush. The gap between the first movable scraper 41 and the second movable scraper 42 forms a suction nozzle 8, and the suction area of ​​the suction nozzle 8 becomes smaller. The air suction port 31 is in the water absorption mode, thereby absorbing the liquid. It should be noted that when the second movable scraper 42 swings forward to the second position, the maximum range of its swinging is not to fit with the first movable scraper 41 as much as possible, so as to prevent the two from fitting together to form a sealed state, thereby affecting the absorption of the liquid.

[0058] The second scraper assembly 4 of this embodiment includes a movable scraper 43 and a fixed scraper 44. Figures 5 to 8 As shown, specifically, the movable scraper 43 includes a connecting end 431 and a contact end 432, and the end of the connecting end 431 is provided with a protruding structure 433, and the protruding structure 433 can be pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle; the contact end 432 is a first scraper, and the first scraper is fixed to an end of the connecting end 431 away from the protruding structure 433 by rubber wrapping or gluing, and the first scraper can contact the cleaned surface; in this embodiment, the first scraper is made of soft material, and the soft material can make the first scraper better sealed when in contact with the cleaned surface, thereby making the suction effect of the suction port 31 better.

[0059] The fixed scraper 44 includes a fixed end 441 and a contact end 442. The fixed end 441 can be fixed on the housing 1. The contact end 442 is a second scraper. The second scraper is fixed to an end away from the fixed end 441 by rubber coating or gluing. The second scraper can contact the cleaned surface. In this embodiment, the second scraper is made of a soft material. The soft material can make the second scraper better sealed when in contact with the cleaned surface, thereby making the suction effect of the air suction port 31 better. In this embodiment, the scraper assembly 4 of this structure also includes a scraper connector 45, which is fixedly mounted on the nozzle rear cover 15 by screws 71.

[0060] In this embodiment, if Figure 6and Figure 7 As shown, the connecting end 431 of the movable scraper strip 43 is movably connected to the shell 1 away from the roller brush 21, and the contact end 432 of the movable scraper strip 43 that contacts the cleaned surface swings around the connecting end 431; the fixed end 441 of the fixed scraper strip 44 is fixedly connected to the shell 1 close to the roller brush 21; specifically, the protruding structure 433 of the connecting end 431 of the movable scraper strip 43 is pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle, so that the contact end 432 thereof can swing around the connecting end within the range of the suction nozzle 8; the fixed end 441 of the fixed scraper strip 44 is fixed to the base 11 by bonding, snapping, screws, etc., so that the contact end 442 contacts the cleaned surface, and the fixed scraper strip 44 is set at an angle to the cleaned surface.

[0061] in, Figure 6 FIG. 4 is a schematic diagram of a state where the second scraper strip assembly 4 structure swings to the first position. Specifically, Figure 6 As shown, when the cleaning component 100 moves along the first moving direction, the movable scraper bar 43 swings backward and swings as close to the fixed scraper bar 44 as possible to keep the movable scraper bar 43 away from the nozzle front cover 14; at this time, the position of the fixed scraper bar 44 does not change, and the gap between the movable scraper bar 43 and the nozzle front cover 14 forms the nozzle 8, and the suction area of ​​the nozzle 8 becomes larger, and the air suction port 31 is in the dust suction mode, thereby absorbing large particles of dust.

[0062] Figure 7 This is a schematic diagram of the state of the second scraper assembly 4 structure swinging to the second position. When the cleaning assembly 100 moves along the second moving direction, the movable scraper 43 swings forward, and the movable scraper 43 swings to a position away from the fixed scraper 44. The movable scraper 43 fits with the suction nozzle front cover 14 away from the roller brush 21. The gap between the movable scraper 43 and the suction nozzle front cover 14 forms the suction nozzle 8, and the suction area of ​​the suction nozzle 8 becomes smaller. The air suction port 31 is in the water absorption mode, thereby absorbing the liquid. It should be noted that when the movable scraper 43 swings forward to the second position, the maximum range of its swinging is not to fit with the suction nozzle front cover 14 as much as possible, so as to prevent the two from fitting together to form a sealed state, thereby affecting the absorption of the liquid.

[0063] The above are the structures of the two scraper bar assemblies 4 of this embodiment. The scraper bar assemblies 4 of the two structures can change the suction area of ​​the suction nozzle 8 during the movement of the cleaning assembly 100, thereby changing the cleaning mode of the air suction port 31, so as to achieve the absorption of liquid and large dust particles through the cleaning assembly 100. Of course, in other possible implementation schemes, there are many other structures of the scraper bar assembly 4, as long as they can change the cleaning mode of the air suction port 31, they are all within the scope of protection of this application.

[0064] Of course, it is understandable that the swing of the scraper bar assembly 4 may not be limited to the action of the cleaning assembly 100 and the cleaned surface, and a driving mechanism may be provided on the scraper bar assembly 4, that is, the scraper bar assembly 4 may be automatically driven.

[0065] Specifically, in another feasible technical solution of the present embodiment, the scraper assembly 4 can be driven by the driving member 110. When the driving member 110 corresponds to the first driving direction, the scraper assembly 4 swings to the first position, the suction area of ​​the suction nozzle 8 becomes larger, and the suction port 31 is in the dust suction mode; when the driving member 110 corresponds to the second driving direction, the scraper assembly 4 swings to the second position, the suction area of ​​the suction nozzle 8 becomes smaller, and the suction port 31 is in the water suction mode.

[0066] Among them, the driving member 110 can be realized by a rotary motor (not shown) and a reducer (not shown) connected to the rotary motor, and can also be realized by a linear motor (not shown), etc., and this embodiment does not make specific limitations on this. For example, the driving member 110 adopts the structure of a rotary motor and a reducer, and the power input end of the scraper assembly 4 is connected to the output end of the reducer; the scraper assembly 4 can be set on the front cover 14 of the suction nozzle; the driving member 110 is connected to the scraper assembly 4, and the driving member 110 drives the scraper assembly 4 to rotate, and the moving trajectory of the scraper assembly 4 is an arc trajectory. Specifically, the first driving direction is clockwise, and the driving member 110 can drive the scraper assembly 4 to swing to the first position, so that the suction area of ​​the suction nozzle 8 becomes larger, and the suction port 31 is in the dust suction mode; the second driving direction is counterclockwise, and the driving member 110 can drive the scraper assembly 4 to swing to the second position, so that the suction area of ​​the suction nozzle 8 becomes smaller, and the suction port 31 is in the water suction mode.

[0067] The following takes the scraper assembly 4 of the second structure as an example, and the movable scraper 43 can be driven by the driving member 110. Specifically, the first driving direction is the clockwise direction, and the driving member 110 can drive the connection end 431 of the movable scraper 43 to rotate in the clockwise direction, thereby driving the contact end 432 of the movable scraper 43 to swing to a position close to the fixed scraper 44, so that the suction area of ​​the suction nozzle 8 becomes larger, and the suction port 31 is in the dust suction mode. The second driving direction is the counterclockwise direction, and the driving member 110 can drive the connection end 431 of the movable scraper 43 to rotate in the counterclockwise direction, thereby driving the contact end 432 of the movable scraper 43 to swing to a position close to the front cover 14 of the suction nozzle, so that the suction area of ​​the suction nozzle 8 becomes smaller, and the suction port 31 is in the water suction mode.

[0068] For another example, the driving member 110 is a linear motor, and the power input end of the scraper assembly 4 is connected to the power output end of the linear motor; the scraper assembly 4 can make reciprocating motion parallel to the cleaned surface along the driving direction of the linear motor. The first driving direction is the backward direction, the scraper assembly 4 swings to the first position, the suction area of ​​the suction nozzle 8 becomes larger, and the suction port 31 is in the dust suction mode; the second driving direction is the forward direction, the scraper assembly 4 swings to the second position, the suction area of ​​the suction nozzle 8 becomes smaller, and the suction port 31 is in the water suction mode.

[0069] Further, in this embodiment, the driving member 110 is used to output corresponding driving power according to the received control instruction to drive the scraper assembly 4 to move. The control instruction received by the driving member 110 may be triggered by the controller 120 in the cleaning assembly 100 of this embodiment, or may be triggered by the user touching the corresponding control key, or may be issued by the user outputting the corresponding control voice, etc., which is not specifically limited in this embodiment.

[0070] In specific implementation, the cleaning component 100 provided in this embodiment further includes a sensor 130 and a controller 120. The sensor 130 is disposed on the end surface of the cleaning component 100 close to the cleaned surface; more specifically, the sensor 130 can be disposed at a position of the end surface close to the fixed scraper strip 44. Fig. 9 As shown, the controller 120 is connected to the driving member 110 and the sensor 130, and is used to send corresponding control instructions to the driving member 110 when it is determined that the cleaning mode needs to be switched based on the sensing information uploaded by the sensor 130. The sensor 130 can be a sensing device that can identify the size of particles on the cleaned surface in the prior art, and this embodiment does not specifically limit this.

[0071] Specifically, if the sensing information uploaded by the sensor 130 is image information, the controller 120 can perform image recognition on the image information and determine the size of the particles, and then determine whether the cleaning mode needs to be switched according to the range of the determined particle size. For example, the cleaning mode includes: a water absorption mode mainly for water absorption and a dust absorption mode mainly for dust absorption, and can also be a general mode for both water absorption and dust absorption. For example, the preset range includes: range 1 is less than or equal to D1; range 2 is greater than or equal to D2, and range 3 is greater than D1 and less than D2. Range 1 corresponds to the water absorption mode; range 2 corresponds to the dust absorption mode, and range 3 corresponds to the general mode. When the information of the detected particle size is D3; the controller 120 determines through comparison that D3 is greater than D2, it belongs to range 2, and the current cleaning component 100 is in the water absorption mode, then it is determined to switch the current water absorption mode to the dust absorption mode; at this time, the controller 120 sends a control instruction to the driving member 110 to drive the scraper assembly 4 to move in the direction close to the roller brush 21 to complete the absorption of particles. The controller 120 generates corresponding control instructions based on the image information sensed by the sensor 130, and sends the corresponding control instructions to the driving member 110. The driving member 110 drives the scraper assembly 4 to swing to a specified position, so that the suction area of ​​the suction nozzle 8 changes, thereby changing the cleaning mode of the suction port 31, so as to achieve the absorption of liquid and large particles of dust through the cleaning assembly 100.

[0072] The first embodiment of the present application provides a cleaning component 100, including: an air suction port 31 of the cleaning air duct 3 and the shell 1 form a suction nozzle 8 that can absorb dirt; a scraper bar component 4 that contacts the cleaned surface is arranged at the suction nozzle 8; the scraper bar component 4 can swing through the movement of the cleaning component 4 and the action of the cleaned surface, or the drive of the driving member 110; when the scraper bar component 4 is in different positions of the suction nozzle, the suction area of ​​the suction nozzle 8 can be changed, thereby changing the cleaning mode of the air suction port 31, so as to realize the absorption of liquid and large particles of dust through the cleaning component 100, and no dirt will remain on the surface after cleaning, and the cleaning effect is good.

[0073] The second embodiment of the present application provides a cleaning machine 200. Since the cleaning machine 200 adopts the cleaning assembly 100 of the first embodiment, the components in the cleaning machine 200 of the second embodiment can refer to the markings of the components in the first embodiment.

[0080] Figure 3It is a schematic diagram of the state of the first scraper assembly 4 structure swinging to the second position. When the cleaning assembly 100 moves along the second moving direction, the first movable scraper 41 and the second movable scraper 42 both swing forward, and the first movable scraper 41 and the second movable scraper 42 swing to a position away from the roller brush 21. The first movable scraper 41 fits with the suction nozzle front cover 14 away from the roller brush. The gap between the first movable scraper 41 and the second movable scraper 42 forms a suction nozzle 8, and the suction area of ​​the suction nozzle 8 becomes smaller. The air suction port 31 is in the water absorption mode, thereby absorbing the liquid. It should be noted that when the second movable scraper 42 swings forward to the second position, the maximum range of its swinging is not to fit with the first movable scraper 41 as much as possible, so as to prevent the two from fitting together to form a sealed state, thereby affecting the absorption of the liquid.

[0081] The second scraper assembly 4 of this embodiment includes a movable scraper 43 and a fixed scraper 44. Figures 5 to 8 As shown, specifically, the movable scraper 43 includes a connecting end 431 and a contact end 432, and the end of the connecting end 431 is provided with a protruding structure 433, and the protruding structure 433 can be pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle; the contact end 432 is a first scraper, and the first scraper is fixed to an end of the connecting end 431 away from the protruding structure 433 by rubber wrapping or gluing, and the first scraper can contact the cleaned surface; in this embodiment, the first scraper is made of soft material, and the soft material can make the first scraper better sealed when in contact with the cleaned surface, thereby making the suction effect of the suction port 31 better.

[0082] The fixed scraper 44 includes a fixed end 441 and a contact end 442. The fixed end 441 can be fixed on the housing 1. The contact end 442 is a second scraper.

In this embodiment, the scraper assembly 4 of this structure also includes a scraper connector 45, which is fixedly mounted on the nozzle rear cover 15 by screws 71.

[0083] In this embodiment, if Figure 6 and Figure 7As shown, the connecting end 431 of the movable scraper strip 43 is movably connected to the shell 1 away from the roller brush 21, and the contact end 432 of the movable scraper strip 43 that contacts the cleaned surface swings around the connecting end 431; the fixed end 441 of the fixed scraper strip 44 is fixedly connected to the shell 1 close to the roller brush 21; specifically, the protruding structure 433 of the connecting end 431 of the movable scraper strip 43 is pivotally connected to the rib position 9 in the cavity of the front cover 14 of the suction nozzle, so that the contact end 432 thereof can swing around the connecting end within the range of the suction nozzle 8; the fixed end 441 of the fixed scraper strip 44 is fixed to the base 11 by bonding, snapping, screws, etc., so that the contact end 442 contacts the cleaned surface, and the fixed scraper strip 44 is set at an angle to the cleaned surface.

[0084] in, Figure 6 Schematic diagram of the state where the second scraper strip assembly 4 structure swings to the first position, specifically, Figure 6 As shown, when the cleaning component 100 moves along the first moving direction, the movable scraper bar 43 swings backward and swings as close to the fixed scraper bar 44 as possible to keep the movable scraper bar 43 away from the nozzle front cover 14; at this time, the fixed scraper bar 44 does not change, and the gap between the movable scraper bar and the nozzle front cover 14 forms the nozzle 8, and the suction area of ​​the nozzle 8 becomes larger, and the air suction port 31 is in the dust suction mode, thereby absorbing large particles of dust.

[0085] Figure 7 This is a schematic diagram of the state in which the second scraper assembly 4 structure swings to the second position. When the cleaning assembly 100 moves along the second moving direction, the movable scraper 43 swings to a position away from the fixed scraper 44. The movable scraper 43 fits with the suction nozzle front cover 14 away from the roller brush 21. The gap between the movable scraper 43 and the suction nozzle front cover 14 forms the suction nozzle 8, and the suction area of ​​the suction nozzle 8 becomes smaller. The air suction port 31 is in the water absorption mode, thereby absorbing the liquid. It should be noted that when the movable scraper 43 swings forward to the second position, the maximum range of its swinging is not to fit with the suction nozzle front cover 14 as much as possible, so as to prevent the two from fitting together to form a sealed state, thereby affecting the absorption of the liquid.
