[0065] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0066] The cleaning device generally comprises a body 100, a roller brush 200, a scraper bar 310, a dirt suction port 900 and a dirt suction channel located inside the cleaning device and connected to the dirt suction port 900. The cleaning device can clean dirt on the surface to be cleaned through the roller brush 200, and suck dirt on the ground through the dirt suction port 900, and the sucked dirt enters the dirt suction channel through the dirt suction port 900. The scraper bar 310 is arranged at the bottom of the body 100, and the scraper bar 310 is located at the rear side of the roller brush 200, and is configured to abut against the surface to be cleaned, so as to push the dirt on the surface to be cleaned forward during the forward movement of the cleaning device; the function of the cleaning device is to clean solids and liquids on the ground, wherein the roller brush 200 can rotate around its own axis, and part of the work of cleaning and picking up solids and liquids on the surface to be cleaned is completed by the roller brush 200. Specifically, the roller brush 200 can clean the solid and liquid on the ground only when it contacts the surface to be cleaned. When the surface of the roller brush 200 contacts and rubs against the surface to be cleaned, the roller brush 200 can adsorb the solid and liquid on the surface to be cleaned on the surface of the roller brush 200, and take them away from the surface to be cleaned as the roller brush 200 rotates. During the rotation of the roller brush 200, the solid and liquid on the surface of the roller brush 200 will first separate from the surface of the roller brush 200 due to their own gravity. The solid or liquid that is freely separated from the surface of the roller brush 200, and the solid or liquid that is forcibly separated from the surface of the roller brush 200 by the necessary structure will be sucked into the sewage suction channel by the sewage suction port 900.

[0067] In the related art, the roller brush 200 may get entangled with hair during operation of the cleaning device. Although the hair on the roller brush 200 can be scraped off by designing a scraping tooth or other structure near the roller brush 200, this method cannot completely solve the problem of hair entanglement, nor can it automatically clean the hair hanging on the scraping tooth, requiring the user to further manually clean it, which is very inconvenient.

[0068] Through research, technicians have found that the difficulty in cleaning the hair tangled by the roller brush 200 is the result of the combined effects of the Coanda effect and the Bernoulli principle. Figure 1 As shown, the Coanda Effect is also called the wall attachment effect or the Coanda Effect. Its main manifestation is the tendency of the fluid (water flow or air flow) to deviate from the original flow direction and flow along the protruding surface of an object. That is, when there is surface friction between the fluid and the surface of the object it flows through, as long as the curvature is not large, the fluid will flow along the surface of the object. Specifically, in the cleaning device of the present application, although the air suction direction of the suction port 900 behind the roller brush 200 is vertically upward, due to the existence of the Coanda effect, the airflow direction will deflect to a certain extent along with the surface of the roller brush 200, so that airflow is formed on part of the surface of the roller brush 200. Figure 2As shown, the roller brush 200 rotates at a high speed during operation, so that the airflow near the surface of the roller brush 200 flows rapidly along with the roller brush 200. According to Bernoulli's principle, the fast-flowing airflow on the surface of the roller brush 200 generates a low-pressure area near the surface of the roller brush 200. The air pressure in the area far away from the roller brush 200 will press the hair toward the roller brush 200, causing the hair to stick to the surface of the roller brush 200, which can easily cause the hair to curl. The long hair in a wet state has enhanced adhesion and is more likely to get tangled.

[0069] Based on this, Figure 3-8 As shown, an embodiment of the present application provides a cleaning component for a cleaning device, and the arrows in the figure indicate the flow direction of the airflow. As shown in the figure, the cleaning component mainly includes a roller brush 200, a scraper bar assembly 300 and an air supply assembly 400. The roller brush 200 is rotatably arranged on the body 100; the scraper bar assembly 300 includes a scraper bar 310 located behind the roller brush 200, and a dirt suction port 900 is formed between the scraper bar assembly 300 and the roller brush 200, and a plurality of air outlet holes 311 are opened on the scraper bar 310; the air supply assembly 400 is arranged on the body 100, and is configured to supply airflow into the scraper bar 310 and discharge it through the air outlet holes 311.

[0070] The roller brush 200 is rotatably arranged on the body 100 of the cleaning device. The roller brush 200 is usually cylindrical and can rotate at high speed when the cleaning device is working. The roller brush 200 is used to pick up solid matter or liquid on the ground and remove dirt from the surface to be cleaned through its rotation. The scraper bar assembly 300 includes a scraper bar 310 located behind the roller brush 200. The main function of the scraper bar 310 is to contact the surface to be cleaned and push the dirt to the dirt suction port 900 during the forward movement of the cleaning device. The scraper bar 310 is provided with a plurality of air outlet holes 311, which are used to discharge the air flow delivered by the air supply assembly 400 from the inside of the scraper bar 310. A dirt suction port 900 is formed between the scraper bar 310 and the roller brush 200. The function of the dirt suction port 900 is to absorb the dirt and other waste separated from the roller brush 200, and further introduce these dirt into the interior of the cleaning device through the dirt suction channel for dust collection. That is, the air supply assembly 400 is disposed on the body 100 of the cleaning device and is configured to supply airflow into the scraper bar 310. The airflow is discharged through the air outlet 311 on the scraper bar 310 and blown toward the surface of the roller brush 200, thereby reducing the airflow pressure difference on the surface of the roller brush 200 due to the high-speed rotation, and preventing hair and other materials from being entangled on the roller brush 200.

[0071] When the cleaning device is started, the roller brush 200 starts to rotate at a high speed, and the roller brush 200 contacts and rubs against the surface to be cleaned, so that the dirt is carried away by the surface of the roller brush 200 and sent to the dirt suction port 900, and the scraper bar 310 follows closely to ensure that the dirt that the roller brush 200 fails to clean is cleaned in time and pushed forward to the area covered by the dirt suction port 900. When the roller brush 200 rotates at a high speed, the air flow speed near the surface of the roller brush 200 is fast. According to the Bernoulli principle, a low-pressure area is generated on the surface of the roller brush 200. Due to the existence of the pressure difference, the surface of the roller brush 200 is easy to absorb light substances such as long hair in the air and make them entangled on the surface of the roller brush 200. In order to break the pressure difference caused by high-speed rotation, the air supply component 400 supplies airflow to the scraper bar 310, and the airflow is discharged through the air outlet 311 on the scraper bar 310, and finally blows to the surface of the roller brush 200. This airflow can reduce the low-pressure area formed on the surface of the roller brush 200, prevent hair or other dirt from firmly adhering to the surface of the roller brush 200 due to the pressure difference, and reduce the risk of entanglement. In addition, after the pressure difference in the area on the surface of the roller brush 200 is broken, the hair and other substances that have been attached to the roller brush 200 can be effectively made to fall off the roller brush 200 more easily and be sucked into the dirt suction port 900. In this way, even if hair or dirt is attached to the surface of the roller brush 200, the interference of the airflow can effectively reduce the probability of such dirt continuing to entangle on the roller brush 200, and can be more easily cleaned up during the operation of the roller brush 200.

[0072] To sum up, in this embodiment, the air supply component 400 supplies air flow into the scraper strip 310 and discharges it through the air outlet 311. The air flow discharged through the air outlet 311 blows toward the roller brush 200, which can break the pressure difference caused by the high-speed rotation of the roller brush 200, so that the hair is not easily entangled on the roller brush 200 due to the existence of the pressure difference. Even if it is entangled on the roller brush 200, it is easy to detach from the roller brush 200 under interference.

[0073] In some embodiments, the air outlet 311 is opened on the front of the scraper 310, the scraper 310 is made of a flexible material, and the cleaning device has a stationary state and a forward state; Figure 3 As shown, in the static state, the air outlet 311 on the front side of the scraper strip 310 faces the roller brush 200; Figure 4-5 As shown, in the forward state, the free end of the scraper bar 310 rubs against the surface to be cleaned and flips in the direction away from the roller brush 200, and the air outlet 311 on the front of the scraper bar 310 faces the surface to be cleaned between the roller brush 200 and the scraper bar 310. The airflow destroys the low-pressure area generated by the high-speed rotation of the roller brush 200, and the airflow effectively suppresses the hair from being attached to the roller brush 200 due to the pressure difference, thereby reducing the risk of hair entanglement.

[0074] When the cleaning device does not move forward or backward, the cleaning device is in a stationary state. When the cleaning device is placed on the surface to be cleaned, the free end of the scraper strip 310 is only in contact with the surface to be cleaned, and no relative movement occurs. The scraper strip 310 is in a relatively natural state. The front side of the scraper strip 310 and the air outlet 311 opened on the front side of the scraper strip 310 are directly facing the roller brush 200. At this time, starting the cleaning component can directly make the airflow discharged from the air outlet 311 blow toward the surface of the roller brush 200.

[0075] When the cleaning setting moves forward, as Figure 4-5 As shown, the cleaning device is in a forward state, the scraper bar 310 contacts and moves relative to the surface to be cleaned, and the friction force causes the free end of the scraper bar 310 to flip backwards, and the direction of the air outlet 311 on the front of the scraper bar 310 flips to obliquely downward, facing the surface to be cleaned between the scraper bar 310 and the roller brush 200. After the cleaning component is started, the gas ejected from the air outlet 311 on the front of the scraper bar 310 will blow toward the surface to be cleaned, and the gas will be reflected by the surface to be cleaned and blow toward the surface of the roller brush 200, then the pressure difference caused by the high-speed rotation of the roller brush 200 will be broken, making it difficult for the hair to be adsorbed and entangled, and finally sucked into the sewage tank by the negative pressure generated in the sewage suction port 900 area.

[0076] In some embodiments, the air outlet 311 is also provided on the back of the scraper strip 310; Figure 3 As shown, the air outlet 311 on the back of the scraper strip 310 faces the surface to be cleaned on the back side of the scraper strip 310; Figure 4-5 As shown, in the forward state, the air outlet 311 on the back of the scraper strip 310 faces the bottom surface of the cleaning device.

[0077] When the cleaning device is not moving forward or backward, the cleaning device is in a stationary state, the scraper bar 310 is in a relatively natural state, and the back side of the scraper bar 310 and the air outlet holes 311 opened on the back side of the scraper bar 310 are directly facing the surface to be cleaned behind the roller brush 200. At this time, starting the cleaning component can directly make the airflow discharged from the air outlet holes 311 on the back side of the scraper bar 310 blow toward the cleaned surface to be cleaned behind the roller brush 200, effectively promoting the rapid evaporation or drying of water stains, thereby improving the drying effect after cleaning and avoiding the cleaning effect being affected by residual water stains.

[0078] When the cleaning setting moves forward, as Figure 4-5As shown, the cleaning device is in a forward state, the scraper bar 310 contacts and moves relative to the surface to be cleaned, and the friction force causes the free end of the scraper bar 310 to flip backwards, and the direction of the air outlet 311 on the back of the scraper bar 310 flips to obliquely upward, toward the bottom surface of the cleaning device behind the scraper bar 310. After the cleaning component is started, the gas ejected from the air outlet 311 on the back of the scraper bar 310 will blow toward the bottom surface of the cleaning device behind the scraper bar 310, and the gas is reflected by the bottom surface of the device to be cleaned and blown toward the cleaned surface behind the roller brush 200, which effectively promotes the rapid evaporation or drying of water stains, thereby improving the drying effect after cleaning and avoiding the cleaning effect being affected by residual water stains.

[0079] In this embodiment, an air outlet 311 is provided on the back of the scraper strip 310. Figure 3 In the static state shown, the airflow can be directly blown to the cleaned surface behind the scraper strip 310. Figure 4-5 When the cleaning device moves forward in the forward state shown, the airflow is blown toward the bottom of the cleaning device through the air outlet 311 on the back of the scraper bar 310, and then reflected to the cleaned surface, thereby accelerating the drying process of water stains, reducing water stain retention, and ensuring that the airflow direction in different working states can always meet the cleaning needs. The natural flipping mechanism of the scraper bar 310 is combined with the direction adjustment of the air outlet 311, and the airflow direction can be adaptively adjusted in different states without the need for additional control structures, which simplifies the design and improves the cleaning efficiency.

[0080] On the basis of the above-mentioned embodiment, the cleaning device also has a retreat state, such as Figure 6-7 As shown, in the retreat state, the air outlet 311 on the back of the scraper bar 310 faces the surface to be cleaned on the back side of the scraper bar 310, and the air outlet 311 on the front side of the scraper bar 310 faces the roller brush 200. When the cleaning device moves backward, the cleaning device is in the retreat state, the scraper bar 310 contacts and moves relative to the surface to be cleaned, and the friction force causes the free end of the scraper bar 310 to flip forward, and the direction of the air outlet 311 on the back of the scraper bar 310 flips to obliquely downward, toward the surface to be cleaned after cleaning behind the scraper bar 310, and the direction of the air outlet 311 on the front side of the scraper bar 310 is still directly toward the roller brush 200.

[0081] This embodiment expands the working state of the cleaning device and adds a backward state to further enhance the versatility of the device during the cleaning process. The scraper bar 310 is provided with a plurality of air outlets 311, which are distributed on the front and back of the scraper bar 310, for discharging airflow. The air supply assembly 400 delivers the airflow into the scraper bar 310 through a pipeline, and the airflow is discharged from the air outlets 311 of the scraper bar 310, providing a blowing function to promote water stain removal, accelerate drying, and reduce hair entanglement on the roller brush 200. Specifically, when the cleaning device moves backward, the scraper bar 310 remains in contact with the surface to be cleaned, but relative movement occurs, and the friction force causes the free end of the scraper bar 310 to flip forward. At this time, the direction of the air outlet 311 on the back of the scraper bar 310 is flipped to obliquely downward, facing the cleaned surface to be cleaned, and the air outlet 311 on the front of the scraper bar 310 will still remain facing the roller brush 200 after a certain direction flip. At this time, the air outlet 311 on the front side of the scraper strip 310 continues to blow air toward the roller brush 200, which helps to break the low-pressure area on the surface of the roller brush 200 and reduce the entanglement of hair; while the air outlet 311 on the back side of the scraper strip 310 faces the cleaned surface, further accelerating the drying of water stains and avoiding residual moisture from affecting the final cleaning effect.

[0082] When the cleaning device is in the retracted state, if the free end of the scraper bar 310 remains in contact with the surface to be cleaned, the water stains or dirt remaining during the cleaning process may be pushed backwards, affecting the cleaning effect and even causing repeated contamination problems. Therefore, in some embodiments, when the cleaning device is in the retracted state, the free end of the scraper bar 310 is disengaged from the surface to be cleaned. By separating the free end of the scraper bar 310 from the surface to be cleaned in the retracted state, water stains or dirt will not be scraped in the retracted state, thereby preventing secondary contamination of the cleaned area. At the same time, the airflow can be used to continue to dry and organize the cleaned area. This design greatly improves the applicability and user experience of the cleaning device, especially in cleaning scenarios that require frequent switching of the direction of movement.

[0083] In order to make the free end of the scraper strip 310 separate from the surface to be cleaned in the retracted state, in some embodiments, as Figure 3-7 As shown, the scraper bar assembly 300 includes a protrusion 312 protruding from the back of the scraper bar 310. In the retracted state, the protrusion 312 rubs against the surface to be cleaned, causing the scraper bar 310 to flip toward the roller brush 200, and the protrusion 312 abuts against the surface to be cleaned.

[0084] By providing a protrusion 312 on the back of the scraper bar 310, the scraper bar 310 can be automatically turned over in the retreat state, so that the free end of the scraper bar 310 is separated from the surface to be cleaned, so as to avoid the free end of the scraper bar 310 from contacting the surface to be cleaned to produce a backward scraping effect, thereby maintaining the cleaning and drying effect. The scraper bar assembly 300 preferably includes a plurality of protrusions 312, which are arranged on the back of the scraper bar 310 and form a certain height relative to the main body of the scraper bar 310. The protrusion 312 has wear resistance and can be repeatedly rubbed against the surface to be cleaned without affecting its function and life. When the cleaning device is in the retreat state, the protrusion 312 on the back of the scraper bar 310 first contacts the surface to be cleaned and generates friction. The friction force acts on the protrusion 312, causing the scraper bar 310 to flip around its installation position, causing the free end of the scraper bar 310 to automatically tilt in the direction close to the roller brush 200 and completely separate from the surface to be cleaned. After the scraper bar 310 is flipped over, the air outlet 311 on the front side is still facing the roller brush 200, and continues to interfere with the airflow on the roller brush 200 to prevent hair entanglement. The air outlet 311 on the back side keeps discharging airflow toward the surface to be cleaned, promoting the rapid drying of water stains in the cleaning area. When the cleaning device is not moving, the protrusion 312 contacts the surface to be cleaned, but no obvious friction is generated. The scraper bar 310 is in a natural state, and the air outlets 311 on the front and back sides act on the roller brush 200 and the surface to be cleaned respectively. When the cleaning device moves forward, the free end of the scraper bar 310 contacts the surface to be cleaned to complete the cleaning of the dirt. The protrusion 312 only serves as an auxiliary support when the cleaning device moves backward, and does not interfere with the normal operation of the scraper bar 310.

[0085] In the above embodiment, the protrusion 312 enables the free end of the scraper strip 310 to automatically flip in the backward state, effectively avoiding the problem of water stains being scraped in the opposite direction during the cleaning process. In addition, the front and back air outlets 311 of the scraper strip 310 can still work normally in the backward state, realizing the simultaneous cleaning of the roller brush 200 and the drying of the surface to be cleaned. The protrusion 312 has a simple and efficient structural design, and the scraper strip 310 can be flipped without additional transmission parts, reducing the system complexity and failure rate, and is suitable for the structural improvement needs of most cleaning equipment. It is a practical and easy-to-promote solution.

[0086] In the related art, during the self-cleaning process of the cleaning device, the implementation method is to place the cleaning device on the base station and then spray water to the roller brush 200 and run the roller brush 200 in forward and reverse rotation and idle rotation. However, the effect of this self-cleaning is not comprehensive. The main reason is that the water disturbed by the rotation of the roller brush 200 is limited in the cleaning position and cleaning area. The main cleaning part of the cleaning device is reflected on the roller brush 200, and the sewage suction port 900 and the parts above are difficult to be cleaned in place. The cleaning component proposed in the aforementioned embodiment of the present application can help solve this problem. The principle is that during the self-cleaning process of the cleaning device, a part of the bottom surface of the cleaning device is soaked in the cleaning water of the base station, the roller brush 200 rotates forward and reversely in the cleaning water of the base station, and blows air through the exhaust hole of the scraper 310. The water on the bottom surface of the roller brush 200 is disturbed by the gas at high frequency, and the water disturbed by high frequency impacts the roller brush 200, the sewage suction port 900 and other positions. The corresponding impact sputtering can achieve a cleaning effect in multiple areas. Specifically, the high-frequency disturbed cleaning water flow can cover the surface of the roller brush 200, including the hair, dirt, etc. on the roller brush 200, which can be fully removed; the disturbed water flow can enter the sewage suction port 900 area through impact and splashing, and clean the sewage suction port 900 and its surroundings; due to the randomness of water flow disturbance and impact, part of the water flow may cover the opening area of ​​the sewage suction channel, further cleaning the entrance of the sewage suction channel.

[0087] The present application exhausts air into the water body of the base station through the exhaust holes on the scraper bar 310, and uses high-frequency disturbed water flow to fully clean the roller brush 200 and the surrounding area of ​​the suction port 900, significantly improving the efficiency and coverage of the self-cleaning process of the cleaning equipment. This design is not only simple in structure and low in cost, but also can be seamlessly integrated with existing cleaning equipment, providing an innovative solution for the self-cleaning technology of cleaning equipment.

[0088] In order to further improve the cleaning effect of the roller brush 200, the dirt suction port 900 and the surrounding areas during the self-cleaning process of the cleaning device, this embodiment proposes an optimized design, using a scraper bar assembly 300 with a reciprocating sliding function, and realizing more efficient and comprehensive cleaning through the movement of the scraper bar 310 combined with the effect of airflow. Specifically, Figure 3-9As shown, the scraper bar assembly 300 includes a fixing member 320, a driving member 330 and a scraper bar 310, wherein the fixing member 320 is slidably arranged on the body 100, a first pipeline 321 is arranged on the fixing member 320, the scraper bar 310 is connected to the fixing member 320, a second pipeline 313 is opened in the scraper bar 310, the air outlet 311 is connected to the second pipeline 313, and the first pipeline 321 is respectively connected to the air supply assembly 400 and the second pipeline 313; the driving member 330 is configured to drive the fixing member 320 to slide reciprocatingly relative to the body 100, so as to drive the scraper bar 310 to reciprocate in the direction of approaching and moving away from the roller brush 200. During the self-cleaning process, the scraper bar 310 can be used to reciprocate, extend and slide, and blow air at the same time. The water on the bottom of the roller brush 200 is disturbed at high frequency by the reciprocating scraper bar 310 and the gas. The high-frequency disturbed water impacts the roller brush 200, the surrounding area of ​​the suction port 900 and other positions, and the corresponding impact sputtering achieves a cleaning effect in multiple areas.

[0089] In the self-cleaning mode, the air supply assembly 400 provides a stable airflow to the first pipeline 321, and the airflow is ejected from the air outlet 311 via the second pipeline 313 of the scraper bar 310. The driving member 330 causes the scraper bar 310 to slide back and forth in the direction of approaching and moving away from the roller brush 200, forming a dynamic cleaning mode. The exhaust is combined with the movement of the scraper bar 310, and the water flow is subjected to the high-frequency disturbance of the airflow and the movement of the scraper bar 310, and is forced to produce strong impact and splashing. The high-frequency disturbed water flow continuously impacts the surface of the roller brush 200, especially its gaps and parts that are difficult to clean. With the reciprocating sliding of the scraper bar 310 and the disturbance of the airflow, the accumulated water and attachments around the suction port 900 are dynamically washed away, further improving the cleaning effect. The splashing water flow then covers the area above the suction port 900, achieving comprehensive cleaning of multiple areas.

[0090] The reciprocating sliding action of the scraper bar 310 combined with the air flow disturbance can effectively clean the hard-to-reach parts of the roller brush 200, the suction port 900 and the surrounding area, expand the cleaning range, and avoid the limitations of the cleaning effect in the static mode. The design is simple and easy to integrate into the existing cleaning equipment without significantly increasing the equipment volume or manufacturing cost.

[0091] The selection of the drive element 330 needs to be determined according to the working requirements and operation scenarios of the equipment, including but not limited to motors, pneumatic drives and mechanical drives. Motor drives are suitable for occasions that require high-precision adjustment, pneumatic drives are suitable for environments with high response speed requirements, and mechanical drives are suitable for situations where cost requirements are low but reliability is still required. Different drive methods can be used flexibly to ensure that the cleaning equipment works efficiently and stably.

[0092] In some embodiments, Figure 8As shown, the air outlet 311 is arranged on the scraper strip 310 along the axial direction of the roller brush 200, which can further optimize the airflow discharge effect and coverage. Specifically, the air outlet 311 is arranged along the axial direction to cover the entire length of the roller brush 200, avoiding airflow interference at a single concentrated point, which is conducive to breaking the low-pressure area generated by the high-speed rotation of the roller brush 200 in its entire axial extension, so that the hair and other dirt on the surface of the entire roller brush 200 lose adhesion and are easily sucked into the dirt suction port 900, thereby improving the efficiency of hair or dirt being separated from the surface of the roller brush 200 and avoiding cleaning dead corners.

[0093] Preferably, the air outlet holes 311 are evenly distributed on the scraper strip 310 along the axial direction of the roller brush 200, so that the air flow can be evenly discharged along the axial direction of the roller brush 200 through the air outlet holes 311 on the scraper strip 310, and the spacing of the air outlet holes 311 can be flexibly adjusted according to the axial length of the roller brush 200 and the air flow requirements.

[0094] In some embodiments, Figure 8 As shown, two first pipelines 321 are provided and are respectively provided at the two ends of the fixing plate along the axial direction of the roller brush 200, and the second pipeline 313 extends along the axial direction of the roller brush 200, and the two first pipelines 321 are respectively connected to the two ends of the second pipeline 313. This design can effectively reduce the pressure loss of the airflow during the transportation process and improve the uniformity of the airflow output by the scraper 310. The airflow enters the two ends of the second pipeline 313 through the two first pipelines 321 respectively, and the second pipeline 313 receives the airflow from both ends at the same time and converges to the middle along the second pipeline 313, thereby improving the airflow transportation efficiency, reducing the airflow pressure loss that may occur in the long axial transportation, compensating for the problem of air pressure loss caused by the reduction of air volume in the middle area of ​​the second pipeline 313, making the airflow pressure in the second pipeline 313 as evenly distributed as possible, and ensuring that the air outlet 311 on the scraper 310 achieves relatively balanced exhaust within the axial range of the roller brush 200. The connection between the two first pipelines 321 and the second pipeline 313 preferably adopts a streamlined design to reduce airflow resistance and vortex phenomenon.

[0095] By setting up a structure in which two first pipelines 321 are connected to the second pipeline 313 at both ends, this embodiment realizes bidirectional drive of air flow delivery, evenly distributes the air flow pressure along the axial direction of the roller brush 200, optimizes the air flow output effect, reduces the pressure attenuation problem of single-end air supply, improves the uniformity of air flow distribution, and improves the overall performance of the cleaning component. This design not only effectively solves the shortcomings of single-end air supply, but also provides reliable technical support for the axial cleaning task of the long roller brush 200.

[0096] In some embodiments, Figure 3-10As shown, the cleaning component for the cleaning device also includes a third pipeline 500, and two third pipelines 500 are also provided. The two ends of the third pipeline 500 are respectively connected to the air supply component 400 and the first pipeline 321, and at least the portion of the third pipeline 500 close to the first pipeline 321 is made of flexible material. The setting of the flexible material enables the third pipeline 500 to be free from movement restriction or obstruction when the fixing member 320 and the scraper strip 310 reciprocate relative to the body 100, thereby ensuring the smooth supply of airflow. Specifically, during the reciprocating sliding of the scraper strip 310, the flexible part can adapt to the changes in the movement trajectory of the fixing member 320, and effectively avoid pipeline damage or airflow interruption caused by rigid connection by bending, stretching or compression, thereby improving the stability and durability of the cleaning component, and ensuring that the air outlet 311 continues to perform its cleaning function.

[0097] The present application also accordingly protects a cleaning device, such as Figure 3-10 As shown, the cleaning device includes a body 100 and a cleaning assembly provided in the aforementioned embodiment. Specifically, the cleaning device can efficiently clean the surface to be cleaned through the synergistic effect of the roller brush 200, the scraper bar assembly 300 and the air supply assembly 400 in the cleaning assembly, while effectively reducing the phenomenon of the roller brush 200 being entangled with hair and improving the cleaning efficiency of hair and dirt. In addition, the cleaning assembly can also generate high-frequency disturbed airflow through the exhaust holes of the scraper bar 310 in the self-cleaning mode of the cleaning device, so as to achieve multi-point impact cleaning of the roller brush 200, the sewage suction port 900 and its surrounding areas, thereby further optimizing the self-cleaning effect of the device.

[0098] In some embodiments, the cleaning device is a floor scrubber, and the body 100 includes a body 110 and a base 120, the body 110 is rotatably connected to the base 120, the roller brush 200 and the scraper assembly 300 are arranged on the base 120, and the air supply assembly 400 is arranged on the body 110. The body 110 is roughly a rectangular parallelepiped, and of course it can also be other shapes such as a cylinder. The body 110 is usually provided with a power device for generating cleaning power and an energy storage device for providing energy. Of course, in different embodiments, the power device and the energy storage device can also be arranged on other components of the cleaning device, such as the base 120. The base 120 and the handle 700 are respectively provided at both ends along the extension direction of the body 110. The base 120 is arranged at one end of the body 110 close to the surface to be cleaned, and the base 120 can move on the surface to be cleaned, so as to clean the surface to be cleaned. The walking wheel 600 is arranged on the base 120 and contacts the surface to be cleaned. It is configured to drive the base 120 to move on the surface to be cleaned and provide rolling friction to reduce resistance. The handle 700 for the user to hold and operate is arranged at the end of the body 110 away from the surface to be cleaned, so that the handle 700 is at a certain height from the surface to be cleaned in most cases, so that the user does not need to bend over to operate, thereby improving the comfort of operation. In order to further improve the comfort of different users and take into account different usage conditions, the body 110 can rotate relative to the base 120, thereby changing the angle between the body 110 and the base 120 and the height of the body 110 from the ground.

[0099] A fan unit is provided in the body 110 of the floor scrubber, and a dirt suction port 900 is provided on the base 120. The fan unit is configured to suck dirt on the surface to be cleaned after being connected to the dirt suction port 900 through a dirt suction channel. On the basis of the above-mentioned embodiment, in order to reasonably utilize the structural space of the floor scrubber product, the air supply component 400 in the cleaning component of the present application is specifically implemented by a fan unit, and the air suction function of the fan unit is used to suck air from the dirt suction port 900, and the exhaust of the fan unit is collected and provided to the air outlet 311 of the scraper 310. In this embodiment, the air suction function of the fan unit is not only used to suck dirt on the surface to be cleaned, but also connected to the dirt suction port 900 through the dirt suction channel to ensure that the dirt can be smoothly sucked into the body 100. The exhaust function of the fan unit will provide the air or airflow sucked in from the suction port 900 to the air outlet 311 of the scraper 310 after passing through the fan unit. The air outlet 311 of the scraper 310 can effectively clean the surface of the roller brush 200 through the discharge of airflow, prevent hair and other debris from being entangled on the roller brush 200, or effectively evaporate water stains on the surface to be cleaned.

[0100] This design effectively utilizes the function of the existing structural fan unit of the floor scrubber. The dual function of the fan unit not only enhances the dirt suction performance, but also utilizes wind force in conjunction with the design of the scraper bar 310 to discharge air, thereby reducing the modification cost of the existing floor scrubber, optimizing the space utilization of the floor scrubber, and improving the cleaning efficiency of the equipment.

[0101] Preferably, the third pipeline 500 is a hose, and the fan unit has an air intake end and an air exhaust end. The air intake end is connected to the sewage suction channel, and the air exhaust end is connected to the first pipeline 321 on the fixing member 320 through the hose, so that the exhaust air is transferred to the scraper 310, and then discharged from the air outlet 311 of the scraper 310, so that the scraper 310 blows air to disturb the low-pressure area on the surface of the roller brush 200 and dry the residual water on the ground. One end of the hose is sleeved on the exhaust end of the fan unit, and the other end is connected to the scraper 310 on the base 120, and its function is to collect and transfer the exhaust of the fan unit to the scraper assembly 300. The exhaust end of the fan unit designed on the fuselage 110 is located on the left and right sides of the fuselage 110, and can be used to respectively sleeve two hoses. The two hoses can be located on the left and right sides of the fuselage 110, and run along the fuselage 110 to the base 120. Through the buckle limit, the pipe is completed from the hole in the middle of the rotating shaft 800 connected to the base 120 at the end of the fuselage 110, and then the pipes are respectively run to the left and right of the base 120 to the scraper assembly 300, and sleeved on the first pipeline 321 on the fixing part 320 in the scraper assembly 300. The third pipeline 500 is selected as a hose to effectively adapt to the rotation between the fuselage 110 and the base 120, and ensure that the exhaust channel of the air supply assembly 400 is always unobstructed, thereby ensuring that the blowing function of the scraper 310 is not affected by the change in the angle of the fuselage 110, and continuously provides a cleaning effect.

[0102] In some embodiments, the cleaning device further includes a base station, which is used to place the base 120. Specifically, the base station is designed as an auxiliary accessory of the cleaning device, which is used to store the base 120 and provide additional functions. For example, when the cleaning device is not in use, the base station can be used as a fixed parking position to keep the device tidy and storage stable. In addition, the base station can also integrate other functions, such as self-cleaning, charging or maintenance support. In the self-cleaning function, a cleaning liquid container and a drainage structure can be provided inside the base station. When the base 120 is placed on the base station, the base station can supply cleaning liquid to the cleaning components such as the roller brush 200 and the scraper 310 of the cleaning device, and complete efficient cleaning through the cooperation of the roller brush 200, the scraper assembly 300 and other structures. Through this design, the cleaning device can not only complete the cleaning task of the ground, but also realize its own efficient cleaning and maintenance through the base station, extend the service life of the equipment and reduce the user's operating burden, further expand the functions and application scenarios of the cleaning device, and enhance the user's experience.
