Description

Technical Field

[0001] The present application belongs to the technical field of cleaning appliances, and in particular relates to a cleaning machine with a rotating assembly. Background Art

[0002] For cleaning machines such as floor scrubbers, vacuum cleaners, and sweepers, during their operation, the cleaning parts will rotate and contact with the surface to be cleaned to clean the surface to be cleaned. During the rotation, the cleaning parts absorb the dirt on the surface to be cleaned onto their outer surfaces, and scrape the dirt off and suck it into the sewage tank through the scraping parts that are tightly fitted with the cleaning parts. However, the cleaning parts that rotate and wipe the surface to be cleaned are simultaneously subjected to the friction of the ground and the scraping force of the scraping parts, which will cause the outer surface of the cleaning parts to be worn, resulting in a continuous decrease in its surface area, thereby weakening the contact force between the scraping parts and the outer surface of the cleaning parts, and the scraping effect of the scraping parts on the dirt on the cleaning parts becomes worse, or even unable to scrape the dirt, affecting the cleaning effect of the cleaning machine; in addition, when cleaning the dirt, the operator needs to manually separate the scraping parts from the cleaning parts and clean the dirt on the scraping parts, which affects the user experience.

[0003] To address this technical problem, the prior art proposes a scraping member with a drive element that can selectively abut against a cleaning member under the action of the drive element. This ensures that the scraping member remains in contact with the cleaning member under the action of the drive element during the floor scrubbing process, while also allowing for selective separation from the cleaning member in accordance with other cleaning applications. This facilitates the suction of dirt from the scraping member into the suction port, eliminating the need for the user to manually move the scraping member for cleaning. However, this technology has the following defects: the existing scraping members that are moved by the driving members are usually controlled by setting driving members or transmission members at both ends of the scraping members, and the scraping members that cooperate with the cleaning members are usually long strips with roughly the same axial length as the cleaning members. This makes the force point located at the end of the scraping member, which easily forms a stress concentration phenomenon at both ends of the scraping member. Moreover, applying a force at the end of the scraping member to drive the scraping member to move can easily cause instability in the movement process of the scraping member, resulting in uneven contact force between the scraping member and the cleaning member, affecting the cleaning effect. Moreover, during the operation of the cleaning member, friction force is continuously applied to the scraping member, which is affected by the friction force of the cleaning member, further aggravating the stress concentration phenomenon at both ends of the scraping member, affecting the structural strength of the scraping member. Utility Model Content

[0004] The present application provides a cleaning machine with a rotating assembly to solve the technical problems of low structural strength, short service life and uneven scraping force on the scraping members in traditional cleaning machines caused by stress concentration.

[0005] At least one of the above technical problems.

[0006] The technical solutions adopted in this application are:

[0007] A cleaning machine with a rotating assembly includes a floor brush housing and a power member, a cleaning member and a rotating assembly arranged on the floor brush housing. The rotating assembly includes a scraping member, and the rotating assembly rotates relative to the floor brush housing. It is characterized in that the rotating assembly also includes a rotating part having a first curved surface, and the power member cooperates with the rotating part to rotate the rotating assembly. The floor brush housing is also provided with a liquid separating member extending in a direction parallel to the axis of the cleaning member, and the liquid separating member is provided with a second curved surface. The first curved surface and the second curved surface are relatively slidably matched.

[0008] The cleaning machine with a rotating assembly described in this application also includes the following additional technical features:

[0009] The liquid separating component is arranged above the scraping component, and the first arc-shaped surface at least partially covers the outer periphery of the liquid separating component.

[0010] The first arcuate surface extends along the axial direction of the second arcuate surface, and a length ratio of the first arcuate surface to the second arcuate surface is in a range of 0.5-1, wherein a length ratio of the second arcuate surface to the cleaning member is in a range of 0.8-1.2.

[0011] A dirt suction port is further provided below the scraping member for collecting dirt scraped off by the scraping member. When the scraping member abuts against the cleaning member, the side of the rotating portion away from the first arc-shaped surface forms at least a part of the dirt suction port.

[0012] A flexible scraping strip is provided above the scraping member, and the scraping member has a scraping position in contact with the cleaning member and a separation position in contact with the cleaning member. When the scraping member is in the separation position, the flexible scraping strip is in contact with the cleaning member. When the scraping member is in the scraping position, the flexible scraping strip is separated from the cleaning member.

[0013] The rotating assembly is provided with an upper sealing component that cooperates with the liquid separating component.

[0014] The scraping member includes a scraping bar, a first comb tooth and a second comb tooth, the first comb tooth and the second comb tooth are longitudinally arranged along the length direction of the cleaning member, and the teeth of the first comb tooth and the teeth of the second comb tooth are staggered.

[0015] The power member is a driving machine having a power gear, and the rotating assembly is provided with a driven gear adapted to the power gear. The driving machine drives the scraping member through gear meshing transmission, so that the scraping member has a scraping position in contact with the cleaning member or a separation position separated from the cleaning member.

[0016] The rotation angle of the scraping member from the scraping position to the separation position is α. When the scraping member is at the separation position, the distance between the scraping member and the cleaning member is D, 20°≤α≤30°, 4mm≤D≤6mm.

[0017] The floor brush housing is further provided with a lower sealing member that cooperates with the rotating assembly, and the lower sealing member is slidably engaged with the rotating assembly.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0019] 1. The cleaning machine of the present application is provided with a cleaning member, which wipes dirt from the surface to be cleaned by rotating the cleaning member. A rotating assembly with a scraping member and a power member that can drive the rotating assembly to rotate are also provided in the floor brush housing. A liquid separator extending along the axis of the cleaning member is provided on the floor brush housing, and cleaning liquid is transported to the cleaning member through the liquid separator, which can improve the dirt removal ability of the cleaning member and enhance the cleaning effect on the surface to be cleaned. On this basis, the rotating assembly is configured to include a rotating portion having a first curved surface, and the liquid separator is provided with a second curved surface. The first curved surface and the second curved surface are slidably matched, so that the scraping member can rotate under the drive of the first curved surface. The power member drives the first curved surface to rotate, thereby rotating the scraping member, and the first curved surface is slidably matched with the second curved surface of the liquid separator. The second curved surface provided on the liquid separator extending along the axial direction also extends along the axis, so that the first curved surface that slides with the first curved surface is more evenly supported by the second curved surface in the axial direction. On the one hand, it can guide the rotation of the rotating part, so that the rotating part can rotate along the extension direction of the first curved surface and the second curved surface. This ensures that the scraping member rotates along the preset trajectory, improving the movement stability of the scraping member. When the scraping member abuts the cleaning member, the scraping force is applied to the cleaning member more evenly, ensuring a stable scraping effect on the dirt on the cleaning member without excessively damaging the outer surface of the cleaning member, which helps to increase the service life of the cleaning member and the scraping member. On the other hand, the setting of the first curved surface and the second curved surface provides a larger force-bearing surface for the rotation of the rotating component. The force applied to the rotating component during rotation is evenly distributed to the contact surface of the first curved surface and the second curved surface, reducing the possibility of stress concentration during the rotation of the rotating component and providing a guarantee for the structural strength of the rotating component.

[0020] 2. As a preferred embodiment of the present application, the liquid separator is arranged above the scraper, so that the rotating assembly including the scraper is located between the liquid separator and the floor brush housing, which improves the installation stability and rotation stability of the rotating assembly, while reducing the probability of interference and contact between the rotating assembly and other components of the cleaning machine during rotation, which helps to maintain the structural integrity of the rotating assembly. The liquid separator used to supply liquid to the cleaning member or the surface to be cleaned is usually arranged axially to achieve uniformity of liquid supply, and the first arc-shaped surface at least partially covers the outer periphery of the liquid separator, so that the first arc-shaped surface used to drive the scraper to rotate extends at least partially along the axial direction, and can be reliably installed by covering the liquid separator, thereby improving the uniformity and reliability of the axial force when the scraper is in different positions. On the one hand, since the sewage attached to the outer surface of the cleaning member may splash outside the cleaning member due to the centrifugal force caused by the rotation of the cleaning member, the first curved surface can shield the sewage splashing in the direction of the liquid separation member, thereby reducing the difficulty of cleaning the liquid separation member for the user. On the other hand, the first curved surface can shield the liquid separation member to a certain extent, reducing the area of ​​the liquid separation member exposed to the user's field of view, thereby improving the user's viewing experience.

[0021] 3. As a preferred embodiment of the present application, the first and second curved surfaces are arranged to extend axially along the cleaning element. The second curved surface is provided on the liquid separator, and its length ratio to the cleaning element is in the range of 0.8-1.2. To ensure that the cleaning element can be evenly wetted by the liquid separator and to ensure the cleaning effect on the surface to be cleaned, the length of the liquid separator is approximately the same as or slightly longer than the cleaning element in the axial direction. However, due to certain component interference or installation deviations that may occur during the component arrangement of the product, the ratio range is approximately between 0.8-1.2. The first and second curved surfaces of the rotating assembly slide together to drive the scraping element to rotate. The scraping element has a state of abutment with the cleaning element and a state of separation. To improve the uniformity of the force strength of the rotatable scraping element in the axial direction and ensure the consistency of its force and positional relationship on the cleaning element in the axial direction, the ratio of the axial length of the first and second curved surfaces is in the range of 0.5-1.0. On the one hand, the contact area between the first curved surface and the second curved surface is increased, further reducing the force per unit area during the rotation of the rotating component, and further reducing the possibility of stress concentration during the rotation of the rotating component. In addition, since the cleaning member rotates continuously during the cleaning process, the cleaning liquid attached to it is easily thrown out by the centrifugal force brought about by the rotation of the cleaning member. The same is true for the dirt attached to the cleaning member, and there is a probability of being thrown out. The first curved surface and the second curved surface are arranged to be close to the cleaning member in the length direction, so that the first curved surface and the second curved surface can stop the cleaning liquid and dirt that are thrown out, reducing the probability of the cleaning liquid and dirt being thrown onto the surface to be cleaned, thereby reducing the user's repeated cleaning to a certain extent, and helping to improve the user experience.

[0022] 4. As a preferred embodiment of the present application, by providing a suction port below the scraping member, dirt scraped off by the scraping member can be sucked in, reducing the probability of dirt falling onto the surface to be cleaned under its own gravity, helping to maintain the cleanliness of the surface to be cleaned and improving the user experience. Furthermore, after the cleaning process is completed, the rotating assembly rotates to drive the scraping member to the separated position. Driven by the rotation of the rotating portion, the gap between the cleaning member and the scraping member increases, allowing dirt outside the suction port to more easily enter the suction port. Furthermore, this also enables the suction port cleaning member to more easily suck in dirt from the scraping member, significantly reducing the cleaning pressure exerted by the user on the scraping member, thereby further improving the user experience. When the scraping member and the cleaning member are in abutment, the side of the rotating portion facing away from the first curved surface cooperates to form a portion of the suction port. This allows the rotating portion to not only drive the scraping member to switch between the scraping position and the separated position, but also inherits the function of forming the suction port. On the one hand, the sewage suction port formed by the back of the first curved surface is at least partially curved, so that dirt falling on the curved surface can enter the sewage suction port relatively smoothly under the suction force of the sewage suction port, which is conducive to keeping the surrounding area of ​​the sewage suction port clean. On the other hand, when the scraping member and the cleaning member are in abutment, the first curved surface at least partially slides out so that its back side forms a part of the sewage suction port. When the scraping member and the cleaning member are in a separated state, the originally partially exposed first curved surface rotates toward the inside of the floor brush housing and is collected again inside the floor brush housing. In this way, during the sliding process of the first curved surface, the floor brush housing and the first curved surface interfere with each other, so that dirt adhering to the first curved surface is peeled off and sucked into the sewage suction port under the interference of the floor brush housing, thereby achieving automatic cleaning of the back of the slidable first curved surface.

[0023] 5. As a preferred embodiment of the present application, a flexible scraping strip is provided above the scraping member. When the scraping member is in the scraping position, the flexible scraping strip is separated from the cleaning member to avoid interference with the rotation of the cleaning member. When the scraping member abuts the cleaning member, it can peel off the dirt on the cleaning member and at the same time hinder the rotation of the cleaning member to a certain extent. At this time, the flexible scraping strip is separated from the cleaning member to prevent the cleaning member from being overloaded and causing operational jams that affect the cleaning effect. When the cleaning work is completed and the scraping member is in the separated position, the flexible scraping strip abuts the cleaning member, which can perform a secondary cleaning function for the dirt remaining on the cleaning member that was not scraped off by the scraping member, reducing the residue of dirt, especially hair, on the cleaning member and reducing the cleaning pressure on the cleaning member by the user. At the same time, the dirt between the cleaning member and the suction port that is not collected by the suction port is intercepted to prevent the dirt not collected by the suction port from being thrown outward under the action of centrifugal force and re-contaminating the surface to be cleaned.

[0024] 6. As a preferred embodiment of the present application, an upper sealing member is provided on the rotating assembly, which, on the one hand, seals the gap between the rotating assembly and the liquid separating member, preventing the sewage thrown out by the centrifugal force generated when the cleaning member rotates from the gap between the rotating assembly and the liquid separating member into the interior of the cleaning machine body, thereby reducing the cleaning pressure of the user and providing a guarantee for the normal operation of the cleaning mechanism components; on the other hand, since the sewage thrown out by the cleaning member will be partially adsorbed on the second curved surface of the liquid separating member, the upper sealing member is provided, and as the rotating assembly rotates, the upper sealing member will also slide on the second curved surface, and scrape off the sewage on the second curved surface during the sliding process, saving the user the operation of cleaning the sewage on the second curved surface and improving the user's usage experience.

[0025] 7. As a preferred embodiment of the present application, the scraping element is configured to include a scraping bar, first comb teeth, and second comb teeth. During cleaning, the first comb teeth and the second comb teeth primarily serve to remove dirt from the cleaning element and remove hair entanglement. The staggered arrangement of the first comb teeth and the second comb teeth reduces axial resistance to the cleaning element while ensuring that the cleaning element can be scraped axially by either the first comb teeth or the second comb teeth. The coordinated arrangement of the first comb teeth and the second comb teeth enhances the removal of dirt.

[0026] 8. As a preferred embodiment of the present application, by providing a driving motor with a power gear and providing a driven gear adapted to the power gear on the rotating assembly, the meshing transmission of the driving gear and the driven gear can improve the accuracy of the rotation amplitude of the rotating assembly, thereby realizing smooth switching of the scraping member between the scraping position and the separation position; in addition, the driving motor can control the rotation direction of the rotating assembly by controlling the rotation direction of the driving gear, thereby reducing the difficulty of switching the scraping member between the scraping position and the separation position.

[0027] Furthermore, the rotation angle α and the rotation distance D of the scraping member between the scraping position and the separation position are set to 20°≤α≤30°, 4mm≤D≤6mm, where the angle α includes any value between 20° and 30° and the endpoint values ​​of 20° and 30°, and the distance D includes any value between 4mm and 6mm and the endpoint values ​​of 4mm and 6mm. With such a setting, while ensuring that there is sufficient spacing between the scraping member and the cleaning member to provide cleaning space for dirt attached to the scraping member, the scraping member does not have an excessively large range of motion, can occupy a smaller internal space of the cleaning machine, optimizes the structural design of the cleaning machine, and contributes to the miniaturization of the cleaning machine.

[0044] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0045] The following description sets forth many specific details to facilitate a thorough understanding of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0049] Example 1:

[0050] Cleaning machines for cleaning surfaces include handheld cleaning machines such as floor scrubbers and vacuum cleaners, and self-propelled cleaning machines such as sweeping and mopping robots and mopping robots. This embodiment uses a floor scrubber as an example to illustrate this solution. Those skilled in the art will appreciate that this solution can also be applied to any of the aforementioned cleaning machines for cleaning surfaces.

[0051] The cleaning machine includes a main body and a floor brush pivotally connected to the main body. The floor brush includes a floor brush housing 1, which is provided with a cleaning member 2 that rotates to wipe the surface to be cleaned. The cleaning member 2 can be any wiping member that can rotate to wipe the surface to be cleaned, such as a single cleaning roller, a double cleaning roller, or a crawler-type cleaning cloth. The floor brush housing 1 also includes a liquid distributor 4 for supplying liquid to the cleaning member 2 or the surface to be cleaned, a scraping member 31 for scraping dirt off the cleaning member 2, and a sewage suction port 5 for absorbing dirt. The sewage suction port 5, the scraping member 31, and the floor brush housing 4 are arranged in sequence in the direction of rotation of the cleaning member 2. When cleaning the surface to be cleaned, the floor brush housing 1 provides cleaning liquid to wet the cleaning member 2, and the surface to be cleaned is wiped as the wetted cleaning member 2 rotates. The sewage suction port 5 is typically connected to a sewage suction channel, a sewage bucket, and a sewage suction motor provided on the floor brush and / or the main body. The sewage suction motor operates to generate suction at the sewage suction port. Part of the dirt on the surface to be cleaned enters the sewage suction port 5 under the action of the suction force at the sewage suction port, and part of the dirt adhering to the cleaning member 2 is peeled off by the scraping member 31 and enters the sewage suction port 5 under the action of the suction force at the sewage suction port 5.

[0052] like Figures 1 to 5 As shown, a cleaning machine with a rotating assembly 3 includes a floor brush housing 1 , a rotating assembly 3 with a scraping member 31 , and a power member, which can rotate with the rotating assembly 3 .

[0053] As an optional solution, the power element can be a mechanical power element such as a spring, a torsion spring, etc., which can push the rotating component 3 to rotate without the aid of electricity. Taking the spring as an example, the spring abuts against the rotating component 3 so that the scraping element 31 has a movement tendency to press toward the cleaning element 2. The cleaning element 2 is usually a wiping element with bristles on the surface. As time goes by, some of the bristles will fall off or fall over. If the scraping element 31 is fixedly mounted on the floor brush housing 1, the cleaning element 2 will not be able to always maintain an abutment state with the scraping element 31 after being used for a period of time, which affects the floor washing efficiency. Therefore, by providing a spring on the floor brush housing 1 that can make the scraping element 31 press toward the cleaning element 2, even if the outer diameter of the cleaning element 2 is reduced due to the shedding of bristles or falling over, the scraping element 31 can still maintain an abutment state with the cleaning element 2 under the push of the power element.

[0054] As another implementation method, the power element can be an electric power element, such as a drive motor, a drive gear, etc. The electric power element can directly or indirectly drive the scraping element 31 to rotate by electric drive. Compared with mechanical power elements, the use of electric power elements is more flexible. The scraping element 31 can be kept in contact with the cleaning element 2 at all times by electric drive, or the scraping element 31 can be in a scraping position in contact with the cleaning element 2 or in a separation position separated from the cleaning element by electric drive. Figure 1 、 Figure 2 In the embodiment, the scraping member 31 is in the scraping position. Figure 3 、 Figure 4 In the embodiment, the scraping member 31 is in the separation position. The structure of the rotating assembly 3 is described by taking the scraping member 31 driven by the electric power element having the scraping position and the separation position as an example.

[0055] The cleaning machine of the present embodiment is provided with a cleaning member 2, which absorbs dirt on the surface to be cleaned by rotating the cleaning member 2, and is provided with a rotating component 3 and a scraping member 31. The rotating component 3 drives the scraping member 31 to switch between the scraping position and the separation position by rotating. When the cleaning member 2 is performing the cleaning work, the scraping member 31 is in the scraping position and scrapes off the dirt attached to the cleaning member 2 by abutting against the cleaning member 2, thereby maintaining the cleanliness of the outer surface of the cleaning member 2 and enhancing the cleaning ability of the cleaning member 2 on the surface to be cleaned. When the cleaning work is finished, the rotating component 3 rotates to drive the scraping member 31 to move to the separation position separated from the cleaning member 2, which is convenient for removing dirt attached to the scraping member 31 The invention can clean the dirt by manually moving the scraping member 31, thereby eliminating the need for the user to manually move the scraping member 31 and improving the user experience. The liquid separator 4 is provided on the floor brush housing 1, and the cleaning liquid is transported to the cleaning member 2 through the liquid separator 4, which can improve the dirt removal ability of the cleaning member 2 and enhance the cleaning effect on the surface to be cleaned. On this basis, the rotating assembly 3 is configured to include a rotating portion 32 having a first curved surface 321, and the liquid separator 4 is provided with a second curved surface 41. The first curved surface 321 and the second curved surface 41 are slidably matched, so that the scraping member 31 can rotate under the drive of the first curved surface 321, thereby having a scraping position abutting against the cleaning member 2 and a separation position separated from the cleaning member. The scraping member 31 rotates under the drive of the first curved surface 321, which can guide the rotation of the rotating portion 32 on the one hand, so that the rotating portion 32 can rotate relative to each other along the extension direction of the first curved surface 321 and the second curved surface 41. This ensures that the scraper 31 switches between the scraping position and the separation position along a preset trajectory, improves the movement stability of the scraper 31, and enables the scraper 31 to apply a scraping force to the cleaning member 2 more evenly, without excessively damaging the outer surface of the cleaning member 2 while ensuring a stable scraping effect on the dirt on the cleaning member 2, which helps to increase the service life of the cleaning member 2 and the scraper 31; on the other hand, the setting of the first curved surface 321 and the second curved surface 41 provides a larger force-bearing surface for the rotation of the rotating component 3, and the force applied to the rotating component 3 during rotation is evenly distributed to the contact surface between the first curved surface 321 and the second curved surface 41, reducing the possibility of stress concentration during the rotation of the rotating component 3, and providing a guarantee for the structural strength of the rotating component 3.

[0056] It should be noted that, in this embodiment, the type of cleaning liquid delivered by the liquid-dispensing member 4 to the cleaning member 2 is not limited, and the cleaning liquid may be water, disinfectant, acidic detergent, alkaline detergent, neutral detergent, etc.

[0057] As a preferred implementation manner of the first embodiment of the present invention, the liquid separating member 4 rotates synchronously with the rotation of the rotating assembly 3. The rotating assembly 3 is provided with a third curved surface 322 facing the floor brush housing 1. The floor brush housing 1 is provided with a fourth curved surface 12 adapted to the third curved surface 322. The third curved surface 322 and the fourth curved surface 12 are slidably matched. By setting the third curved surface 322 and the fourth curved surface 12, the third curved surface 322 and the fourth curved surface 12 of the rotating part 32 slide together during the rotation of the rotating part 32. On the one hand, it can play an auxiliary guiding role for the rotation of the rotating part 32. On the basis of the first curved surface 321 and the second curved surface 41 guiding the rotation of the rotating part 32, the third curved surface 322 and the fourth curved surface 12 further limit the rotation direction of the rotating part 32, thereby further reducing the possibility of the rotating part 32 turning and deflecting during the rotation, and improving the movement accuracy of the scraping member 31 between the scraping position and the separation position; on the other hand, the friction between the rotating part 32 and the floor brush shell 1 is the sliding friction between the third curved surface 322 and the fourth curved surface 12, which reduces the friction resistance encountered by the rotating component 3 during the rotation, improves the smoothness of the rotation process of the rotating component 3, and optimizes the structural design of the rotating component 3 and the floor brush shell 1. This embodiment does not limit the relationship between the first curved surface 321 and the third curved surface 322. In one example, the third curved surface 322 is a part of the first curved surface 321 that can form the sewage suction port 5 by rotating; in another embodiment, the first curved surface 321 and the third curved surface 322 are two independent curved structures that together constitute the outer surface of the rotating portion 32.

[0058] Optionally, in the first embodiment, the first arcuate surface 321 is provided with a clamping portion, and the second arcuate surface 41 is provided with a matching portion adapted to the clamping portion. The clamping portion and the matching portion divide the rotation path of the rotating portion 32 into a first section and a second section. When the rotating portion 32 rotates in the first section, the first arcuate surface 321 and the second arcuate surface 41 slide and match; when the rotating portion moves to the junction of the first section and the second section, the clamping portion and the matching portion clamp and match to lock the liquid separating member 4 and the rotating portion 32. When the rotating portion 32 rotates in the second section, the relative positions of the liquid separating member 4 and the rotating portion 32 remain unchanged, that is, through The snap fit between the snapping portion and the matching portion enables the rotating portion 32 to achieve relative sliding with the floor brush housing 1 through the sliding fit between the third curved surface 322 and the fourth curved surface 12, while driving the liquid separating component 4 to move synchronously. At this time, the relative positions of the first curved surface 321 and the second curved surface 41 remain unchanged; and when the rotating portion 32 moves from the second section to the first section, the snap fit between the snapping portion and the matching portion is released, that is, during the movement of the rotating portion 32 in the first section, the first curved surface 321 and the second curved surface 41 maintain relative sliding, and the third curved surface 322 and the fourth curved surface 12 maintain relative sliding.

[0059] As a preferred implementation of this embodiment 1, Figures 1 to 4 As shown, the liquid separating member 4 is disposed above the scraping member 31 , and the first arc-shaped surface 321 at least partially covers the outer periphery of the liquid separating member 4 .

[0060] The liquid separator 4 is arranged above the scraper 31 so that the rotating assembly 3 including the scraper 31 is at least partially wrapped to cover the outer periphery of the liquid separator 4. This improves the installation stability and rotation stability of the rotating assembly 3, while reducing the probability of interference and contact between the rotating assembly 3 and the other components of the cleaning machine during rotation, which helps to maintain the structural integrity of the rotating assembly 3. The liquid separator 4 used to supply liquid to the cleaning member 2 or the surface to be cleaned is usually arranged axially to achieve uniformity of liquid supply. The first curved surface 321 at least partially covers the outer periphery of the liquid separator 4, so that the first curved surface 321 used to drive the scraper 31 to rotate is at least partially extended axially and can be reliably installed by covering the liquid separator 4, thereby improving the uniformity and reliability of the axial force of the scraper 31 when it is in different positions. On the one hand, if there is leakage or a small amount of liquid seeps out of the liquid separator 4, the seeped liquid can flow out along the first curved surface 321 to the scraper 6 and thus infiltrate the cleaning member. On the other hand, during the process of scraping the cleaning member 2, some dirty liquid may enter the floor brush housing 1 through the gap between the scraping member 6 and the liquid separator 4. The first curved surface 321 that cooperates with the arc of the liquid separator 4 can temporarily retain the dirty liquid in the first curved surface 321, reducing the possibility of liquid flowing to other parts of the floor brush housing and avoiding damage to other components.

[0061] Preferably, if Figure 1 、 Figure 3 、 Figure 5As shown, the liquid separator 4 extends along the length direction of the cleaning member 2 and is used to supply liquid to the cleaning member 2 or the surface to be cleaned. This embodiment is described by taking the liquid separator 4 that can supply liquid to the cleaning member 2 as an example. The cleaning machine also includes a liquid supply pipeline and a liquid supply tank connected to the liquid separator 4. When the cleaning machine is running, the cleaning liquid in the liquid supply pipe is provided to the liquid separator 4 through the liquid supply pipeline, and then provided to the cleaning member 2 through the liquid separator 4. As an optional implementation scheme of this embodiment, the liquid separator 4 is provided with a plurality of spaced liquid spray ports 42, and the liquid separator 4 delivers cleaning liquid to the cleaning member 2 through the liquid spray ports 42. Optionally, the liquid spray ports 42 can be multiple and evenly distributed along the axial direction of the liquid separator 4; optionally, the liquid spray ports 42 can be multiple and unevenly distributed along the axial direction of the liquid separator 4, for example, the density of the liquid spray ports 42 in the middle area of ​​the liquid separator 4 is greater than the density of the liquid spray ports 42 at both ends of the liquid separator; or, the density of the liquid spray ports 42 in the middle area of ​​the liquid separator 4 is less than the density of the liquid spray ports 42 at both ends of the liquid separator. The liquid dispensing opening 42 can be freely selected based on the material of the surface to be cleaned, the material of the cleaning element 2, the piping configuration within the liquid dispensing element 4, and other factors. As another implementation of this embodiment, the liquid dispensing element 4 is provided with a slot-shaped opening through which liquid is supplied to the cleaning element 2. It should be noted that this embodiment does not limit the type of cleaning liquid delivered by the liquid dispensing element 4 to the cleaning element 2; it can be water, disinfectant, acidic detergent, alkaline detergent, neutral detergent, or a mixture of one or more of the above cleaning liquids.

[0062] like Figure 1 、 Figure 3 、 Figure 5 As shown, further, in order to improve the cleaning efficiency, the liquid separating member 4 is usually extended axially along the cleaning member 2, and the liquid separating member 4 basically overlaps with the cleaning member 2 in axial length or is slightly larger than the cleaning member 2, so that the cleaning member 2 can be evenly wetted in the axial direction. The length ratio of the second curved surface 41 on the liquid separating member 4 to the cleaning member is in the range of 0.8-1.2. In order to improve the matching strength and rotation reliability of the scraping member 31, the length ratio of the first curved surface 321 that matches the second curved surface 41 to the second curved surface 41 is in the range of 0.5-1.0. For example, the length ratio of the first curved surface 321 to the second curved surface 41 can be any value between 0.5-1.0, such as 0.5, 0.6, 0.7, 0.75, 0.8, 0.88, 0.9, 1.0, etc.

[0063] Optionally, the first curved surface 321 is a continuous curved surface extending continuously in an axial direction parallel to the cleaning member 2. The length ratio of the first curved surface 321 to the second curved surface 41 is 1.0, and the length ratio of the second curved surface 41 to the cleaning member 2 is 1.0. In other words, the axial lengths of the first curved surface 321, the second curved surface 41, and the cleaning member 2 are substantially equal, and the first curved surface 321 completely covers the second curved surface 41 in the axial direction. Driven by the first curved surface 321, the scraping member 31 provided on the rotating assembly 3 is subjected to uniform force in the axial direction.

[0064] Optionally, the first curved surface 321 is a curved surface that extends discontinuously along an axis parallel to the axial direction of the cleaning element 2. As an implementable solution of this embodiment, the first curved surface 321 is composed of two curved segments, each of which mates with the end of the second curved surface 41. The ratio of the axial extension length of the two curved segments to the length of the second curved surface is in the range of 0.5-1.0.

[0065] Optionally, the first curved surface 321 may be a curved surface with a uniform width in its axial extension direction, or may be a curved surface with a variable width, as long as it can cooperate with the second curved surface 41 on the liquid separating member 4 to slide relative to it.

[0066] As a preferred implementation of this embodiment 1, Figure 1 、 Figure 3 As shown, a dirt suction port 5 is further provided below the scraping member 31 for collecting dirt scraped off by the scraping member 31 . When the scraping member 31 abuts against the cleaning member 2 , the side of the rotating portion 32 away from the first arc-shaped surface 321 at least rotates out to form a part of the dirt suction port 5 .

[0067] By providing a suction port 5 below the scraping element 31, dirt scraped off by the scraping element 31 can be sucked in, reducing the probability of dirt falling onto the surface to be cleaned due to its own gravity. This helps maintain the cleanliness of the surface to be cleaned and enhances the user experience. Furthermore, after cleaning is completed, the rotating assembly rotates to drive the scraping element to the separated position. The rotation of the rotating portion widens the gap between the cleaning element 2 and the scraping element 31, allowing dirt outside the suction port 5 to more easily enter the suction port 5. This also allows the suction port cleaning element to more easily suck dirt from the scraping element, significantly reducing the pressure on the scraping element to be cleaned, further enhancing the user experience. When the scraping element 31 and the cleaning element 2 are in contact, the side of the rotating portion facing away from the first curved surface 321 cooperates to form a portion of the suction port 5. This allows the rotating portion 32 to not only drive the scraping element between the scraping position and the separated position, but also further inherit the function of forming the suction port 5. On the one hand, the sewage suction port 5 formed by the back of the first curved surface 321 is at least partially curved, which is conducive to guiding the dirt around the sewage suction port 5 into the sewage suction port 5 under the guidance of the curved surface. It is conducive to keeping the sides of the sewage suction port 5 clean. On the other hand, when the scraping member 31 and the cleaning member 2 are in abutment, the first curved surface 321 at least partially slides out so that its back side forms a part of the sewage suction port 5. When the scraping member 31 and the cleaning member 2 are in a separated state, the first curved surface 321 that was originally partially exposed rotates toward the inside of the floor brush housing 1 and is collected again inside the floor brush housing 1. During the sliding process of the first curved surface 321, at least part of the curved segment that was originally exposed to the outside interferes with the floor brush housing 1, and the dirt adhering to the surface of the curved segment is peeled off, thereby achieving automatic cleaning of the back of the slidable first curved surface 321.

[0068] Preferably, if Figures 1 to 4 As shown, a sewage tank and a sewage suction channel 14 connecting the sewage suction port 5 with the sewage tank are provided inside the floor brush housing 1 . The sewage sucked by the sewage suction port 5 enters the sewage tank through the sewage suction channel 14 for temporary storage.

[0069] As a preferred implementation of this embodiment 1, Figures 1 to 4As shown, a flexible scraper 6 is provided above the scraper 31. The scraper 31 has a scraping position in contact with the cleaning member 2 and a separation position in contact with the cleaning member 2. When the scraper 31 is in the separation position, the flexible scraper 6 is in contact with the cleaning member 2. When the scraper 31 is in the scraping position, the flexible scraper 6 is separated from the cleaning member 31. A flexible scraper 6 is provided above the scraper 31. When the scraper 31 is in the scraping position, the flexible scraper 6 is separated from the cleaning member 2 to avoid interference with the rotation of the cleaning member 2. When the scraper 31 is in contact with the cleaning member 2, it can peel off dirt on the cleaning member 2 while hindering the rotation of the cleaning member 2 to a certain extent. At this time, the flexible scraper 6 is separated from the cleaning member 2 to prevent the cleaning member 2 from being overloaded and causing operational jams that affect the cleaning effect. When the cleaning work is completed and the scraping member 31 is in the separated position, the flexible scraping strip 6 contacts the cleaning member 2, which can perform a secondary cleaning function on the cleaning member 2 that has not been scraped off by the scraping member 31, thereby reducing the amount of dirt, especially hair, left on the cleaning member 2 and reducing the cleaning pressure on the cleaning member 2. At the same time, the flexible scraping strip 6 intercepts the dirt between the cleaning member 2 and the sewage suction port 5 that has not been collected by the sewage suction port 5, preventing the dirt that has not been collected by the sewage suction port 5 from being thrown outward under the action of centrifugal force and re-contaminating the surface to be cleaned.

[0070] Preferably, the flexible scraper strip 6 is made of rubber material and extends along the axial direction of the cleaning member 2 . The length of the flexible scraper strip 6 is similar to that of the cleaning member 2 .

[0071] As a preferred implementation of this embodiment 1, Figures 1 to 4 As shown, the rotating assembly 3 is provided with an upper sealing member 33 that cooperates with the liquid separation member 4. By providing the upper sealing member 33 on the rotating assembly 3, on the one hand, the gap between the rotating assembly 3 and the liquid separation member 4 is sealed, preventing the sewage thrown out by the centrifugal force generated when the cleaning member 2 rotates from entering the body of the cleaning machine through the gap between the rotating assembly 3 and the liquid separation member 4, thereby reducing the cleaning pressure of the user while providing a guarantee for the normal operation of the cleaning mechanism components; on the other hand, since the sewage thrown out by the cleaning member 2 will be partially adsorbed on the second curved surface 41 of the liquid separation member 4, the upper sealing member 33 is provided, and as the rotating assembly 3 rotates, the upper sealing member 33 will also slide on the second curved surface 41 and scrape off the sewage on the second curved surface 41 during the sliding process, eliminating the user's operation of cleaning the sewage on the second curved surface 41 and improving the user's experience.

[0072] As a preferred embodiment of this embodiment, Figure 2 As shown, the rotating assembly 3 is provided with an outwardly protruding first positioning protrusion 35, and the upper seal 33 is provided with a first positioning groove adapted to the first positioning protrusion 35. The upper seal 33 is installed on the rotating assembly 3 through the interference fit between the first positioning protrusion 35 and the first positioning groove.

[0073] This embodiment does not limit the structural form of the upper sealing member 33. In one embodiment, the upper sealing member 33 is as follows: Figure 2 In another embodiment, the upper seal 33 is provided with a first scraping angle whose cross-sectional area gradually decreases from the end closest to the rotating assembly 3 to the end farther from the rotating assembly 3. In this way, when the rotating assembly 3 rotates, the first scraping angle can quickly scrape away the dirty water on the second curved surface 41, thereby achieving self-cleaning of the liquid separator 4 to a certain extent.

[0074] As a preferred implementation of this embodiment 1, Figure 4 As shown, the scraping member 31 includes a scraping strip 311, a first comb tooth 312 and a second comb tooth 313. The first comb tooth 312 and the second comb tooth 313 are arranged longitudinally along the length direction of the cleaning member 2, and the comb teeth of the first comb tooth 312 and the comb teeth of the second comb tooth 313 are staggered.

[0075] The scraping member 31 is configured to include a scraping bar 311, first comb teeth 312, and second comb teeth 313. During cleaning, the first and second comb teeth 312, 313 primarily remove dirt from the cleaning member 2 and remove hair entanglements. The staggered arrangement of the teeth of the first comb 312 and the second comb 313 reduces axial resistance on the cleaning member 2 while ensuring that the cleaning member 2 is scraped axially by either the first comb 312 or the second comb 313. The coordinated arrangement of the first and second comb teeth 312, 313 enhances the removal of dirt.

[0076] Optionally, the scraping member 31 can also be a straight scraping strip; or, the scraping member 31 can be a straight scraping strip and a comb-tooth scraping strip, wherein the straight scraping strip is located above the comb-tooth scraping strip, or, the comb-tooth scraping strip is located above the straight scraping strip; or, the scraping member 31 can be a comb-tooth scraping strip; or, the scraping member 31 can be two comb-tooth scraping strips or any other structure that can scrape off dirt on the cleaning member 2.

[0077] As a preferred embodiment of the first embodiment, a driving machine having a power gear is further provided in the floor brush housing 1, and a driven gear 34 adapted to the power gear is provided on the rotating assembly 3. The driving machine drives the scraping member 31 to abut against or separate from the cleaning member 2 through gear meshing transmission. By providing a driving machine having a power gear and providing a driven gear 34 adapted to the power gear on the rotating assembly 3, the meshing transmission between the driving gear and the driven gear 34 can improve the accuracy of the rotation amplitude of the rotating assembly 3, thereby achieving smooth switching of the scraping member 31 between the scraping position and the separation position; in addition, the driving machine can control the rotation direction of the rotating assembly 3 by controlling the rotation direction of the driving gear, thereby reducing the difficulty of switching the scraping member 31 between the scraping position and the separation position.

[0078] As a preferred embodiment of this embodiment, Figure 8 As shown, the rotation angle of the scraping member 31 from the scraping position to the separation position is α. When the scraping member 31 is at the separation position, the distance between the scraping member 31 and the cleaning member 2 is D, 20°≤α≤30°, 4mm≤D≤6mm. Figure 8 The scraping member 31' at the scraping position and the scraping member 31 at the separation position are shown in the figure. The rotation angle α and the rotation distance D of the scraping member between the scraping position and the separation position are set to 20°≤α≤30°, 4mm≤D≤6mm, where the angle α includes any value between 20° and 30° and the endpoint values ​​of 20° and 30°, and the distance D includes any value between 4mm and 6mm and the endpoint values ​​of 4mm and 6mm. With such a setting, while ensuring that there is sufficient spacing between the scraping member 31 and the cleaning member 2 to provide cleaning space for dirt attached to the scraping member 31, the scraping member 31 does not have an excessively large range of motion, can occupy a smaller internal space of the cleaning machine, optimizes the structural design of the cleaning machine, and contributes to the miniaturization of the cleaning machine.

[0079] As a preferred implementation of this embodiment 1, Figure 2 、 Figure 4 As shown, the floor brush housing 1 is further provided with a lower sealing member 11 that cooperates with the rotating assembly 3 , and the lower sealing member 11 is in sliding cooperation with the rotating assembly 3 .

[0080] By arranging the lower seal 11 on the floor brush housing 1, on the one hand, a sealing effect is played on the gap between the rotating component 3 and the floor brush housing 1, preventing the sewage thrown out by the centrifugal force generated when the cleaning component 2 rotates from entering the interior of the cleaning machine from the gap between the rotating component 3 and the floor brush housing 1, thereby reducing the user's cleaning pressure while providing protection for the normal operation of the cleaning mechanism components; on the other hand, since the sewage thrown out by the cleaning component 2 will be partially adsorbed on the rotating component 3, by arranging the lower seal 11, as the rotating component 3 rotates, the upper seal 33 will also slide relative to the rotating component 3, and scrape off the sewage on the rotating component 3 during the sliding process, reducing the user's cleaning pressure on the rotating component 3 and improving the user's usage experience.

[0081] Preferably, if Figure 2 、 Figure 4 As shown, a third curved surface 322 is provided on the side of the rotating portion 32 facing the floor brush housing 1, and the lower sealing member 11 abuts against and slides relative to the third curved surface 322. The third curved surface 322 mentioned here can be an extension of the first curved surface 321, that is, the first curved surface 321 is bent at the end of the rotating portion 32 and extends toward the floor brush housing 1 to form the third curved surface 322; or the third curved surface 322 and the first curved surface 321 can be separated from each other, and the first curved surface 321 and the third curved surface 322 respectively constitute the outer surfaces of the rotating portion 32 on opposite sides.

[0082] As a preferred embodiment of this embodiment, Figure 5 As shown, the floor brush housing 1 is provided with an outwardly protruding second positioning protrusion 13, and the lower seal 11 is provided with a second positioning groove adapted to the second positioning protrusion 13. The lower seal 11 is installed on the floor brush housing 1 through the interference fit between the second positioning protrusion 13 and the second positioning groove.

[0083] This embodiment does not limit the structural form of the lower sealing member 11. In one embodiment, the lower sealing member 11 is as follows: Figure 2 In another embodiment, the upper seal 33 is provided with a second scraping tip whose cross-sectional area gradually decreases from the side close to the floor brush housing 1 to the side close to the rotating assembly 3. In this way, when the rotating assembly 3 rotates, the second scraping tip can quickly scrape off the dirty water on the rotating assembly 3, thereby achieving a certain degree of self-cleaning of the rotating assembly 3.

[0084] Example 2:

[0085] The structure and principle of the second embodiment are basically the same as those of the first embodiment, with the only difference being:

[0086] The second arcuate surface 41 includes a plurality of arcuate segments arranged at intervals, each of which extends axially along the first arcuate surface 321 , and a length ratio between the first arcuate surface 321 and the longest of the plurality of arcuate segments is in a range of 0.5-1.

[0087] Example 3:

[0088] The structure and principle of the third embodiment are basically the same as those of the first embodiment, with the only difference being:

[0089] The second arcuate surface 41 includes a plurality of arcuate segments arranged at intervals, each of which extends axially along the first arcuate surface 321. The axial extension length of the first arcuate surface 321 is L1, and the sum of the axial extension lengths of the arcuate segments along the first arcuate surface 321 is L2. The ratio of L1 to L2 is in the range of 0.5-1.
