Description

Technical Field

[0001] The present application belongs to the technical field of cleaning appliances, and in particular relates to a cleaning device with a movable scraping component. Background Art

[0002] For cleaning equipment such as floor scrubbers, vacuum cleaners, and sweepers, during their operation, the cleaning parts will come into rotational contact with the surface to be cleaned to clean the surface. During the rotation process, the cleaning parts adhere the dirt on the surface to be cleaned to its outer surface, and the scraping parts that abut against the cleaning parts scrape the dirt off and suck it into the sewage tank. To improve the user experience, the scraping assembly can be movably installed in the floor brush mounting cavity to make the cooperation between the scraping assembly and the cleaning parts more flexible and reliable. However, there is inevitably a movable gap between the movably installed scraping assembly and the mounting cavity. During the floor washing process, liquid enters the mounting cavity through this movable gap, and the scraping assembly has an adverse effect on the floor brush components.

[0003] To address this technical problem, the prior art proposes installing a sealing strip inside the mounting cavity that abuts the scraping assembly. The sealing strip blocks the gap between the scraping assembly and the floor brush to prevent sewage from entering the mounting cavity. However, this arrangement presents the following problems: the sealing strip between the scraping assembly and the floor brush is squeezed longitudinally by the scraping assembly and other components within the floor brush, and is rubbed by the scraping assembly in the direction of its movement. This longitudinal squeezing increases the friction between the remaining sealing components when the scraping assembly moves, causing wear on its outer surface. Furthermore, as the scraping assembly moves away from the cleaning element, the sealing strip is continuously squeezed. Under prolonged pressure, the sealing strip is susceptible to irreversible permanent deformation, thereby affecting the sealing performance of the mounting cavity. That is, the service life of the sealing strip is short, and it is impossible to achieve stable sealing of the installation cavity; in addition, since the sealing strip always maintains contact with the scraping assembly and the floor brush respectively, the sewage that enters the installation cavity through other channels cannot be effectively discharged, which is likely to have an adverse effect on the other components of the floor brush. At the same time, the sewage stored in the installation cavity for a long time will produce odor, affecting the user experience. Utility Model Content

[0004] The present application provides a cleaning device with a movable scraping assembly to solve the technical problems in traditional cleaning devices, such as the inability to maintain a long-term seal in the installation cavity due to the short service life of the sealing strip, and the difficulty in cleaning the sewage in the installation cavity.

[0005] The technical solutions adopted in this application are:

[0006] A cleaning device with a movable scraping assembly includes a floor brush and a cleaning member installed on the floor brush, the floor brush includes a suction port, a scraping assembly and an installation cavity surrounded by a retaining wall, the scraping assembly can be movably installed in the installation cavity and is arranged above the suction port, the scraping assembly is provided with a blocking member, the free end of the blocking member extends toward the installation cavity and cooperates with the scraping assembly to form an isolation cavity, and the retaining wall at least partially extends into the isolation cavity.

[0007] The cleaning device with a movable scraping assembly described in this application also includes the following additional technical features:

[0008] The baffle wall comprises a first baffle wall provided below the dirt scraping assembly, wherein at least a portion of the first baffle wall extends into the isolation cavity and forms a portion of the dirt suction port.

[0009] The blocking member is a flexible structure, and the blocking wall is in contact and sealed with the blocking member.

[0010] The first blocking wall portion extends into the isolation cavity, and an extension line of the extending portion intersects with the blocking member.

[0011] The scraping assembly is further provided with a limiting portion, and the extension line of the first retaining wall extending into the isolation cavity intersects with the limiting portion to block the scraping assembly when it moves to the limit position.

[0012] A first channel is formed between the first blocking wall and the isolation cavity wall, and the first channel is communicated with the installation cavity.

[0013] The cleaning equipment also includes a separatory plate for transporting cleaning liquid to the cleaning member and an infusion tube connected to the separatory plate. The separatory plate is installed on the floor brush through an installation cavity. The installation cavity is provided with a connecting port. The infusion tube passes through the connecting port and is connected to the separatory plate. A third sealing member is provided between the infusion tube and the connecting port.

[0014] The liquid separation plate is connected to the scraping assembly and can move synchronously with the scraping assembly. The third sealing member is made of elastic material and includes a connecting portion connected to the connecting port and a sealing portion abutting the infusion tube. A movable gap is left between the sealing portion and the connecting portion and can approach or move away from the connecting portion as the infusion tube moves.

[0015] The retaining wall further includes a second retaining wall extending vertically, the communication port is opened in the second retaining wall, the connecting portion has a positioning groove adapted to the second retaining wall, and the positioning groove has a first stop surface and a second stop surface abutting against the second retaining wall.

[0016] The third sealing member has a pushing direction for pushing into the communicating port to connect the connecting portion with the communicating port. Along the pushing direction, the third sealing member is provided with a guiding slope at the front end.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] The cleaning device of the present application includes a cleaning member, a scraping assembly movably mounted in a mounting cavity, and a suction port located below the scraping assembly. During cleaning, the cleaning member cleans the surface to be cleaned and absorbs dirt onto the outer surface of the cleaning member. The scraping assembly abuts the cleaning member to scrape dirt off the outer surface of the cleaning member. The suction port is located below the scraping assembly, and dirt scraped off by the scraping assembly is sucked into the suction port below, thereby cleaning the dirt on the surface to be cleaned. To achieve flexible coordination between the scraping assembly and the cleaning member, the scraping assembly is movably mounted in the mounting cavity of the floor brush. To achieve a seal between the movably scraping assembly and the mounting cavity and reduce the ingress of liquid into the mounting cavity, a blocking member extending toward the mounting cavity is provided on the scraping assembly, forming an isolation cavity between the blocking member and the scraping assembly, and allowing the retaining wall of the mounting cavity to at least partially extend into the isolation cavity. The blocking member thereby blocks the gap between the scraping assembly and the mounting cavity, thereby preventing liquid from entering the mounting cavity through the mating point between the scraping assembly and the mounting cavity.

[0019] The movement of the scraping assembly in the installation cavity can be horizontal movement or rotation along the rotation axis. The isolation cavity formed by the scraping assembly and the blocking member partially surrounds the installation cavity blocking wall. On the one hand, the fixed installation cavity blocking wall can play a guiding role during the movement of the scraping assembly, helping the scraping assembly to accurately position itself during the movement. On the other hand, the blocking member arranged outside the blocking wall is almost not subject to the gravity compression of the scraping assembly, the blocking wall or other components of the floor brush, thereby reducing the irreversible deformation of the blocking member caused by long-term pressure, helping to maintain the structural strength of the blocking member and providing a guarantee for the service life of the blocking member; furthermore, the blocking member can move synchronously with the movement of the scraping assembly. With this structure, the scraping assembly is almost not subject to the gravity compression of other components during movement or rotation, and is only subject to the friction assembly in its direction of movement, thereby reducing the resistance of the scraping assembly during movement, reducing damage to the blocking member during movement of the scraping assembly, and avoiding the problem that the blocking member is deformed due to the dual effects of longitudinal compression force and axial friction force for a long time, which leads to a short service life and easy failure.

[0047] 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.

[0048] The following description sets forth many specific details to facilitate a thorough understanding of the present application.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0052] Example 1:

[0053] Cleaning equipment includes 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 1 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 above cleaning equipment.

[0054] The cleaning device includes a body and a floor brush 1 pivotally connected to the body, the floor brush 1 includes a floor brush housing, a cleaning member 2 is installed at the front of the floor brush 1, a mounting cavity 13 is formed in the floor brush housing, and a movable scraping assembly 12 is installed in the mounting cavity 13. As one implementation of this embodiment 1, the movable scraping assembly 12 can be moved under the drive of a mechanical power member, such as the scraping assembly 12 is installed in the mounting cavity 13 in cooperation with a spring, and under the action of the spring force, the scraping assembly 12 has a force in the direction of approaching the cleaning member 2, so that the scraping assembly 12 can always abut against the cleaning member 2 during the operation of the cleaning device. As another implementation of this embodiment 1, the movable scraping assembly 12 can be moved under the drive of a driving power member, which can be a driving motor, etc. The scraping assembly 12 selectively abuts against or separates from the cleaning member 2 under the action of the driving motor. The direction of movement of the scraping component 12 is not limited, whether it is driven by a mechanical power part or a driven power part. Optionally, the scraping component 12 can move in the horizontal direction or pivot around a specified rotation point. It can be understood by those skilled in the art that no matter what driving method the scraping component 12 adopts or in what direction it moves, as long as the scraping component 12 is movably installed in the installation cavity 13, there will inevitably be a gap between the edge of the scraping component 12 and the installation cavity 13, and dirt and / or dirty liquid can easily enter the installation cavity 13 through the gap, making it difficult to clean the installation cavity 13 and the internal components easily adversely affected. Therefore, it is necessary to provide a seal between the scraping component 12 and the installation cavity 13 to prevent dirty liquid from entering the installation cavity 13. If the seal is fixedly mounted to the retaining wall of the mounting cavity 13 and disposed between the mounting cavity 13 and the scraper assembly 12, but the scraper assembly 12 is movably mounted within the mounting cavity 13 and is subject to significant movement during operation, when the scraper assembly 12 moves toward the interior of the mounting cavity 13, whether horizontally or rotationally, the squeezed seal is simultaneously subjected to longitudinal squeezing force and lateral frictional force, and the presence of the longitudinal squeezing force increases the frictional force exerted on the seal by the movement of the scraper assembly 12. Leaving the seal mounted there for a long time will not only cause irreversible deformation of the seal, leading to failure, but will also hinder the movement of the scraper assembly 12.

[0055] To solve this technical problem, Figures 1 to 4As shown, the present application proposes a cleaning device with a movable scraping assembly 12, including a floor brush 1 and a cleaning member 2 installed on the floor brush 1, the floor brush 1 including a dirt suction port 11, a scraping assembly 12 and a mounting cavity 13 for mounting the scraping assembly 12. The scraping assembly 12 can be movably mounted in the mounting cavity 13 and is arranged above the dirt suction port 11. A blocking member 14 is provided on the movable scraping assembly 12 to prevent dirt from entering the mounting cavity 13. The free end 142 of the blocking member 14 extends toward the mounting cavity 13 and cooperates with the scraping assembly 12 to form an isolation cavity 3, and the blocking wall of the mounting cavity 13 at least partially extends into the isolation cavity 3. The blocking member 14 also includes a connecting end 141 installed on the scraping assembly 12, and the free end 142 refers to the part connected to the connecting end 141 and extending in a direction away from the connecting end 141. Compared to solutions that place the blocking member 14 between the mounting cavity 13 and the scraping assembly 12, this solution allows the blocking member 14 to be at least partially separated from the scraping assembly 12. This allows it to be virtually unaffected by the longitudinal forces of the scraping assembly 12 or other components within the floor brush 1. This reduces the resistance between the blocking member 14 and the retaining wall of the mounting cavity 13 when the scraping assembly 12 is in motion, extending the service life of the blocking member 14. Furthermore, the blocking member 14 is not fixedly mounted within the mounting cavity 13, but rather mounted on the movable scraping assembly 12 and having a free end that extends toward the mounting cavity 13 and can engage with the scraping assembly 12 to partially surround the retaining wall of the mounting cavity 13. This provides the blocking member 14 with greater freedom of movement. The relative position of the isolation cavity 3 formed by the blocking member 14 and the retaining wall may change as the scraping assembly 12 moves. However, regardless of this change, the retaining wall at least partially extends into the isolation cavity 3. The blocking member 14 can prevent dirt from entering the mounting cavity 13 through the interface between the scraping assembly 12 and the mounting cavity 13, resulting in a more effective seal.

[0056] The cleaning device of this embodiment 1 includes a cleaning member 2, a scraping assembly 12 movably mounted in a mounting cavity 13, and a sewage suction port 11 located below the scraping assembly 12. When performing cleaning work, the cleaning member 2 cleans the surface to be cleaned and absorbs the dirt to the outer surface of the cleaning member 2. The scraping assembly 12 abuts against the cleaning member 2 to scrape off the dirt on the outer surface of the cleaning member 2 through a scraping action. The sewage suction port 11 is arranged below the scraping assembly 12. The dirt scraped off by the scraping assembly 12 will be sucked up by the sewage suction port 11 below, thereby achieving the cleaning of the dirt on the surface to be cleaned. During the process of dirt flowing through the dirt suction port 11, some of the dirt may move toward the matching gap between the scraping component 12 and the retaining wall of the installation cavity 13. By setting the blocking member 14 and utilizing the isolation cavity 3 formed by the blocking member 14 and the scraping component 12 to surround the retaining wall of the installation cavity 13, the dirt can be stopped and prevented from entering the installation cavity 13 from the gap between the scraping component 12 and the retaining wall of the installation cavity 13, so as to avoid the dirt from causing adverse effects on other components in the installation cavity 13 and reduce the user's cleaning pressure on the installation cavity 13.

[0057] As an implementation of this embodiment 1, the installation cavity 13 is formed by a retaining wall. The retaining wall of the installation cavity 13 that can cooperate with the scraping assembly 12 includes a first retaining wall 4 located on the bottom surface of the installation cavity 13 and a second retaining wall 5 located on the top surface of the installation cavity 13.

[0058] Optionally, the first baffle wall 4 located at the bottom surface of the installation cavity 13 is provided below the scraping assembly 12. In this case, the blocking member 14 that forms the isolation cavity 3 with the scraping assembly 12 is installed on the scraping assembly 12, and is located on the same side of the scraping assembly 12 as the first baffle wall 4, that is, the blocking member 14 is provided on the side of the scraping assembly 12 facing the surface to be cleaned. The first baffle wall 4 at least partially extends into the isolation cavity 3 and partially forms a part of the sewage suction port 11. The sewage suction port 11 is a hollow pipe that is connected to the outside world for allowing sewage suction airflow and dirt to pass through. The first baffle wall 4 forms a part of the sewage suction port 11, and the free end of the blocking member 14 used to form the isolation cavity 3 extends toward the installation cavity 13 and is at least partially provided below the first baffle wall 4 to form a part of the sewage suction port 11 or is partially located in the sewage suction pipe.

[0059] Optionally, a second baffle located on the top surface of the installation cavity 13 is provided above the scraping assembly 12. In this case, the blocking member that forms the isolation cavity 3 with the scraping assembly 12 is installed on the scraping assembly 12 and is located on the same side of the scraping assembly 12 as the second baffle wall, that is, the blocking member is provided on the side of the scraping assembly 12 away from the surface to be cleaned, and is used to prevent dirt from entering the installation cavity 13 from the gap between the scraping assembly 12 and the mating surface on the upper side of the installation cavity 13.

[0060] It is understandable that, regardless of whether the blocking member 14 is located on the upper or lower side of the scraping assembly 12, the method of using the free end of the blocking member 14 and the scraping assembly 12 to form an isolation cavity 3 to prevent external dirt from entering the installation cavity 13 can prevent the free end of the blocking member 14 from being squeezed in the longitudinal direction by other components on the floor brush 1, thereby reducing the squeezing of the blocking member 14 by the longitudinal pressure and reducing the friction between the scraping assembly 12 and the blocking member 14 when the scraping assembly 12 moves, thereby satisfying the purpose of blocking dirt from entering the installation cavity 13 and extending the service life of the blocking member 14. Next, this embodiment 1 takes the solution in which the blocking member 14 is arranged below the scraping assembly 12 to form an isolation cavity 3 that allows the first retaining wall 4 as an example to explain the blocking member 14 and its associated structure.

[0061] As a preferred implementation method of this embodiment 1, Figure 3 As shown, the blocking member 14 is at least partially disposed below the first blocking wall 4 , and a projection of the blocking member 14 toward the first blocking wall 4 at least partially overlaps with the first blocking wall 4 .

[0062] The projection of the blocking member 14 toward the first baffle wall 4 at least partially overlaps with the first baffle wall 4, providing a certain coverage margin for the sealing of the scraping assembly 12 and the first baffle wall 4 by the blocking member 14. When the blocking member 14 follows the movement of the scraping assembly 12 and approaches or moves away from the cleaning member 2, the sealing of the matching part of the scraping assembly 12 and the first baffle wall 4 is always maintained, thereby reducing the impact on the sealing of the installation cavity 13 caused by the movement of the scraping assembly 12, and helping to improve the sealing of the blocking member 14.

[0063] Preferably, the scraping assembly 12 can selectively engage with or disengage from the cleaning member 2. Specifically, the scraping assembly 12 has a scraping position in which it engages with the cleaning member 2 and a separation position in which it separates from the cleaning member 2. The horizontal displacement of the scraping assembly 12 when moving from the scraping position to the separation position is D1. When the scraping assembly 12 is in the separation position, the projection of the blocking member 14 toward the first baffle wall 4 overlaps the first baffle wall 4 by a degree D2, where D2 ≥ D1 > 0. With this arrangement, regardless of the position of the scraping assembly 12, the blocking member 14 can effectively block the mating position between the scraping assembly 12 and the first baffle wall 4, preventing the blocking member 14 from failing to seal the mounting cavity 13 due to movement of the scraping assembly 12.

[0064] Preferably, the scraping assembly 12 always remains in contact with the cleaning member 2 during the floor scrubbing process. The scraping assembly 12 has a scraping position in which it abuts the cleaning member 2 when installed on the floor brush 1, and a separated position in which the cleaning member 2 is removed from the floor brush 1 and pushed to its limit by the powered member. Regardless of whether the scraping assembly 12 is in the scraping position or the separated position, the projection of the blocking member 14 toward the first blocking wall 4 at least partially overlaps with the first blocking wall 4, ensuring that the blocking member 14 effectively prevents dirt from entering the mounting cavity 13 regardless of the position of the movable scraping assembly 12 within its range of motion.

[0065] Optional, such as Figure 3 As shown, the first blocking wall 4 partially extends into the isolation cavity 3 , and the extension line of the extending direction intersects with the blocking member 14 . Figure 3 The middle dashed line a is the extension line of the first barrier wall 4. When the scraping assembly 12 is in the extreme position, it can abut against the blocking member 14, or maintain a certain gap between the scraping assembly 12 and the blocking member 14. This ensures that the scraping assembly 12 can still cooperate with the blocking member 14 to prevent some dirt from entering the installation cavity 13 when it is in the extreme position.

[0066] Optional, such as Figure 4 As shown, the scraping assembly 12 further includes a limiting portion 121 , and the extension line of the first retaining wall 4 in its extending direction intersects with the limiting portion 121 . Figure 3The middle dashed line b is the extension line of the first retaining wall 4. When the scraping assembly 12 is at the limit position, the first retaining wall 4 moves to the limit portion 121 and abuts against the limit portion 121. The limit portion 121 guides the movement direction of the scraping assembly 12 and provides support strength for the scraping assembly 12 after being limited.

[0067] Furthermore, the blocking member 14 is a flexible structure. The blocking member 14 can be in contact and sealed with the blocking wall, or the blocking member 14 can be in clearance fit with the blocking wall.

[0068] As a preferred embodiment of this embodiment 1, a first channel is formed between the first baffle wall 4 and the wall of the isolation chamber 3. One end of the first channel is connected to the sewage suction port 11 through the first baffle wall 4, and the other end is connected to the installation chamber 13. If dirt or sewage enters the first channel or the installation chamber 13 through the gap between the first baffle wall 4 and the isolation chamber 3, the negative pressure at the sewage suction port 11 creates a pressure difference with the first channel, and the dirt in the first channel can still flow out under the action of gravity and / or the suction force at the sewage suction port 11.

[0069] Specifically, if Figure 5 As shown, the first channel includes a sewage discharge gap 7 between the first blocking wall 4 and the blocking member 14, and the sewage discharge gap 7 has a width L, where L≤10 mm.

[0070] By setting the sewage discharge gap 7 between the first retaining wall 4 and the blocking member 14, a channel is provided for sewage that enters the installation cavity 13 through other paths during the operation of the cleaning member 2 to be discharged outwards. Figure 7 The middle dotted line c is the path for sewage to be discharged outward. After the sewage is discharged from the sewage discharge gap 7, it can be sucked into the sewage suction port 11 below to achieve self-cleaning of the installation cavity 13, reducing the cleaning pressure of the installation cavity 13 on the part of the user; in addition, the width of the sewage discharge gap 7 is set to be less than or equal to 10 mm. On the one hand, it ensures that the sewage in the installation cavity 13 has sufficient space to move out of the installation cavity 13, reducing the possibility of sewage discharge being blocked due to the narrow space of the sewage discharge gap 7; on the other hand, it can reduce the possibility of sewage thrown out by the cleaning member 2 entering the installation cavity 13 through the sewage discharge gap 7, thereby providing a guarantee for the sealing of the installation cavity 13 by the blocking member 14.

[0071] Preferably, the blocking member 14 is made of a flexible material, such as rubber. When the sewage suction port 11 is in operation, it rapidly draws in air. The rapid movement of the air causes the air pressure at the sewage suction port 11 to be lower than the air pressure at the cleaning member 2, thereby achieving the suction of dirt from the cleaning member 2. Similarly, there is a pressure difference between the sewage suction port 11 and the installation cavity 13. Under the action of the pressure difference, the sewage in the installation cavity 13 moves toward the sewage suction port 11 through the sewage discharge gap 7. At the same time, because the blocking member 14 is made of an elastic material, it will also deform toward the sewage suction port 11 under the action of the pressure difference, thereby expanding the width of the sewage discharge gap 7, allowing the sewage in the installation cavity 13 to flow out quickly. Regardless of how the blocking member 14 is deformed, the width L of the sewage discharge gap 7 remains L≤10mm. It should be pointed out that the value of L can be any value within 10mm, such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 0.91mm, 0.99mm, 10mm, etc.

[0072] Furthermore, the first channel also includes a flow gap 150 between the scraping assembly 12 and the first baffle 4, and the flow gap 150 is connected to the sewage discharge gap 7. A flow gap 150 is left between the scraping assembly 12 and the first baffle 4, and the flow gap 150 is connected to the installation cavity 13 to allow sewage in the installation cavity 13 to flow out.

[0073] The flow gap 150 set between the scraping component 12 and the first baffle 4 provides a channel for the sewage that enters the installation cavity 13 through other paths during the operation of the cleaning part 2 to be discharged outward, and the sewage suction port 11 is set below the scraping component 12 and the first baffle 4. Since the sewage suction port 11 sucks in the scraped sewage by sucking the air flow, there will be a fast-moving airflow near the sewage suction port 11, and the rapid movement of the airflow will cause the air pressure to drop, thereby forming a pressure difference between the sewage suction port 11 and the installation cavity 13. The sewage in the installation cavity 13 can be sucked out of the installation cavity 13 through the flow gap 150 under the action of the pressure difference and sucked into the sewage suction port 11, which saves the user from manually cleaning the sewage in the installation cavity 13. On the basis of the function of sucking the sewage on the cleaning part 2, the sewage suction port 11 further integrates the function of sucking in the sewage in the installation cavity 13 through the setting scheme under this embodiment. The function is further integrated, the structural design of the cleaning equipment is optimized, and the user experience is improved.

[0074] As a preferred embodiment of this embodiment, a concave flow groove is formed on the side of the scraping assembly 12 facing the first baffle wall 4. The flow groove cooperates with the first baffle wall 4 to form a flow gap 150. This arrangement allows the scraping assembly 12 to maintain a relatively high degree of contact with the first baffle wall 4, thereby allowing the first baffle wall 4 to effectively guide the scraping assembly 12.

[0075] As a preferred implementation of this embodiment 1, Figure 6 As shown, the scraping assembly 12 includes comb teeth 122 and a scraping bar 123 . The comb teeth 122 are disposed below the scraping bar 123 and have a first mounting groove 124 for mounting the blocking member 14 .

[0076] The scraping assembly 12 is configured to include comb teeth 122 and scraping strips 123, which can improve the cleaning effect of the cleaning member 2. For some dirt that is easily entangled on the cleaning member 2, such as hair, yarn balls, etc., the comb teeth 122 can comb them smoothly when they come into contact with them, thereby removing the entanglement. After being combed out by the comb teeth 122, the hair, yarn balls, etc. can be easily scraped off, reducing the probability of these dirt being entangled on the cleaning member 2, thereby reducing the cleaning and maintenance pressure of the cleaning member 2. On this basis, a first mounting groove is provided on the comb teeth 122 to provide a mounting position for the blocking member 14. Therefore, the comb teeth 122 not only have the function of combing dirt, but also integrate the function of providing a mounting position for the blocking member 14. The functions are further integrated, and the structural design of the scraping assembly 12 is optimized.

[0077] Optionally, the scraping assembly 12 can also be a straight scraping bar; or, the scraping assembly 12 can be a straight scraping bar and a comb-tooth scraping bar, wherein, along the rotation direction of the cleaning member 2, the comb teeth 122 are located on the upstream side of the scraping bar 123; or, the comb-tooth scraping bar is located above the straight scraping bar; or, the scraping assembly 12 can be a comb-tooth scraping bar; or, the scraping assembly 12 can be two comb-tooth scraping bars, or any other structure that can scrape off dirt on the cleaning member 2.

[0078] Preferably, the blocking member 14 is made of an elastic material, such as rubber, and the blocking member 14 is interference fit with the first mounting groove 124 .

[0079] Optionally, the scraping assembly 12 may further include one or more scraping bars and a liquid separation plate 9 that can move along with the scraping bars.

[0080] As a preferred example of this embodiment, Figure 7As shown, it also includes a second sealing member 8 provided between the comb teeth 122 and the scraping bar 123. A second mounting groove is provided on the end of the comb teeth 122 facing the scraping bar 123. The second sealing member 8 is interference-fitted with the second mounting groove to seal the gap between the comb teeth 122 and the scraping bar 123. By providing the second sealing member 8 between the comb teeth 122 and the scraping bar 123, the gap between the comb teeth 122 and the scraping bar 123 can be sealed, preventing sewage from entering the mounting cavity 13 through the gap between the comb teeth 122 and the scraping bar 123, which helps to improve the sealing performance of the mounting cavity 13. In addition, the second mounting groove for installing the second sealing member 8 is provided on the comb teeth 122, so that the comb teeth 122 further integrate the function of installing the second sealing member 8. The function is further integrated, and the structural design of the scraping assembly 12 is optimized. Moreover, during the operation of the cleaning member 2, the scraping assembly 12 The component 12 is kept in contact with the cleaning component 2, and the feedback force transmitted to the scraping component 12 by the cleaning component 2 during cleaning will cause the scraping component 12 to vibrate. By arranging a second sealing component 8 between the comb teeth 122 and the scraping bar 123, the second sealing component 8 is respectively in contact with the comb teeth 122 and the scraping bar 123, which can reduce the relative vibration of the comb teeth 122 and the scraping bar 123 caused by the force of the cleaning component 2, improve the working stability of the comb teeth 122 and the scraping bar 123, and avoid the collision and damage of the comb teeth 122 and the scraping bar 123, which helps to increase the service life of the scraping component 12.

[0081] As a preferred embodiment of this embodiment, the second seal 8 is made of an elastic material, such as rubber, and has an interference fit with the second mounting groove. This configuration reduces the installation difficulty of the second seal 8, allowing the second seal 8 to be installed relatively easily within the second mounting groove. Furthermore, since the second seal 8 is made of an elastic material, when the scraper strip 123 and the comb teeth 122 are subjected to relative motion due to vibration or bumps, the second seal 8 can convert the kinetic energy of their motion into the elastic potential energy required for its own deformation, thereby maintaining the installation stability of the scraper strip 123 and the comb teeth 122.

[0082] Preferably, the second seal 8 includes a fixed portion and an extended portion connected to each other. The fixed portion is mounted in the second mounting groove, and the extended portion is located between the comb teeth 122 and the scraper strip 123 and has a first abutting surface that abuts the scraper strip 123 and a second abutting surface that abuts the comb teeth 122. This further improves the vibration absorption performance of the second seal 8 on the scraper strip 123 and the comb teeth 122.

[0083] As a preferred implementation method of this embodiment 1, Figure 8 、 Figure 9As shown, the cleaning device also includes a liquid separator 9 for conveying cleaning liquid to the cleaning member 2 and a liquid infusion tube 10 connected to the liquid separator 9. The liquid separator 9 is installed on the floor brush 1 through the installation cavity 13. The installation cavity 13 is provided with a connecting port. The liquid infusion tube 10 passes through the connecting port and is connected to the liquid separator 9. A third sealing member 110 is provided between the liquid infusion tube 10 and the connecting port. By providing the liquid separator 9 and conveying the cleaning liquid to the cleaning member 2 through the liquid separator 9, the decontamination ability of the cleaning member 2 can be improved, and the cleaning effect on the surface to be cleaned can be enhanced. The provision of the liquid infusion tube 10 provides the liquid separator 9 with a transmission channel for conveying the cleaning liquid, and the provision of the third sealing member 110 in the connecting port can prevent the sewage in the installation cavity 13 from entering the inner cavity of the floor brush 1, thereby improving the sealing performance of the installation cavity 13 and preventing the sewage in the installation cavity 13 from affecting the components in the inner cavity of the floor brush 1.

[0084] Preferably, the liquid separation plate 9 is provided with a liquid spray port connected to the liquid infusion tube 10, and the liquid separation plate 9 delivers cleaning liquid to the cleaning member 2 through the liquid spray port. Optionally, there may be multiple liquid spray ports and they are evenly distributed along the axial direction of the liquid separation plate 9; optionally, there may be multiple liquid spray ports and they are unevenly distributed along the axial direction of the liquid separation plate 9, for example, the density of the liquid spray ports in the middle area of ​​the liquid separation plate 9 is greater than the density of the liquid spray ports at both ends of the liquid separation plate 9; or, the density of the liquid spray ports in the middle area of ​​the liquid separation plate 9 is less than the density of the liquid spray ports at both ends of the liquid separation plate 9. The liquid spray port can be freely selected according to the material of the surface to be cleaned, the material of the cleaning member 2, the pipeline setting in the liquid separation plate 9, etc. As another implementation method of this embodiment 1, a long strip groove-shaped opening is provided on the liquid separation plate 9, and the cleaning member 2 is supplied with liquid through the groove-shaped opening. It should be noted that the present application does not limit the type of cleaning liquid delivered by the liquid separator 9 to the cleaning member 2 , which can be a mixture of one or more of the above cleaning liquids such as water, disinfectant, acidic detergent, alkaline detergent, neutral detergent, etc.

[0085] As a preferred example of this embodiment, Figures 8 to 10 As shown, the liquid separator 9 is disposed above the scraping assembly 12 and can move synchronously with the scraping assembly 12. The third sealing member 110 is made of an elastic material and includes a connecting portion 120 that cooperates with the communication port and a sealing portion 130 that cooperates with the infusion tube 10. Optionally, a movable gap 140 is left between the sealing portion 130 and the connecting portion 120, and the sealing portion 130 can move closer to or away from the connecting portion 120 as the infusion tube 10 moves.

[0086] In this way, as the cleaning member 2 is used for a longer time, its surface area is continuously reduced due to wear. Therefore, the scraping component 12 needs to move toward the cleaning member 2 to maintain the scraping force on the cleaning member 2. The separator plate 9 moves synchronously with the movement of the scraping component 12 to ensure that the cleaning liquid sprayed therefrom can accurately fall on the cleaning member 2 with a continuously shrinking surface area, thereby providing a guarantee for the cleaning effect of the cleaning member 2; in the process of the separator plate 9 moving with the scraping component 12, the infusion tube 10 connected to the separator plate 9 will also move accordingly. Since the third sealing member 110 is made of elastic material, the sealing portion 130 can be squeezed by the infusion tube 10 and move toward or away from the connecting portion 120. When the infusion tube 10 moves, it will drive the sealing portion 130 to deform and maintain the sealing of the space between the infusion tube 10 and the connecting port by the sealing portion 130. On the basis of ensuring the sealing function of the third sealing member 110, the third seal 110 is avoided from restricting the movement of the infusion tube 10, thereby avoiding the third seal 110 from affecting the movement of the separator plate 9.

[0087] As another implementation of this embodiment 1, the sealing portion 130 abuts against the connecting portion 120. When the liquid separation plate 9 moves and causes the infusion tube 10 to move, the sealing portion 130 keeps the infusion tube 10 as stable as possible and only allows the infusion tube 10 to move within the range allowed by its elasticity.

[0088] As a preferred method in this example, Figures 8 to 10 As shown, a vertically extending third retaining wall 6 is provided in the floor brush 1, a connecting port is opened in the third retaining wall 6, the connecting portion 120 has a positioning groove adapted to the third retaining wall 6, and the positioning groove has a first stop surface 1201 and a second stop surface 1202 abutting against the third retaining wall 6.

[0089] A third retaining wall 6 is provided in the floor brush 1. On the one hand, the third retaining wall 6 cooperates with the floor brush 1 to form an installation cavity 13. On the other hand, it cooperates with the positioning groove to limit the movement of the connecting part 120 by limiting the first stop surface 1201 and the second stop surface 1202, thereby ensuring the installation stability of the third seal 110 and reducing the probability of dislocation of the third seal 110 due to vibration, bumps or other factors, thereby providing protection for the sealing of the installation cavity 13.

[0090] As another preferred method in this example, Figure 10As shown, the third seal 110 has a pushing direction for pushing into the connecting port to connect the connecting portion 120 with the connecting port. Along the pushing direction, the third seal 110 is provided with a guiding slope 1101 at the front end. When assembling the third seal 110, the third seal 110 is pushed into the connecting port along the pushing direction. Since the third seal 110 is made of an elastic material, the third seal 110 will simultaneously shrink and deform inward under the action of the guiding slope 1101 during the movement along the pushing direction, thereby partially entering the connecting port and connecting the connecting portion 120 with the connecting port. During the pushing process of the third seal 110, the guiding slope 1101 not only guides the movement of the third seal 110 in the pushing direction, but also provides deformation guidance for the inward deformation of the connecting portion 120 under the squeezing action of the connecting port, thereby improving the installation smoothness of the third seal 110 in many aspects.
