Description

Technical Field

[0001] This utility model relates to the field of smart home technology, specifically to cleaning equipment and cleaning systems. Background Technology

[0002] With the development of society and economy and people’s increasing requirements for home environment, cleaning equipment that integrates floor washing, mopping and vacuuming has emerged and is widely used in people’s lives. In order to improve the convenience of using cleaning equipment, it is generally automatically charged and self-cleaned through base stations.

[0003] Cleaning equipment in related technologies includes roller brushes, roller brush covers, and toothed scrapers. When the cleaning equipment is performing normal floor cleaning, the roller brush rotates at high speed, and the toothed scrapers can scrape off the dirt attached to the roller brush. However, existing cleaning equipment suffers from problems such as easy wear of the roller brush bristles, gradual deterioration of cleaning effect over time, cumbersome self-cleaning process control, high cost, and hinders the promotion and use of the product. Utility Model Content

[0004] In view of this, the present invention provides a cleaning device and a cleaning system to solve the problems of easy wear of the brush bristles of the existing cleaning devices, gradual deterioration of the cleaning effect in the later stage, cumbersome self-cleaning process control, and high cost.

[0005] In a first aspect, this utility model provides a cleaning device, comprising:

[0006] Base;

[0007] A roller brush assembly includes a roller brush and a roller brush cover, the roller brush cover being movably mounted on a base;

[0008] The cleaning component is movably mounted on the base. The cleaning component can move between the cleaning position that is in interference fit with the roller brush and the clearance position that is in clearance fit with the roller brush. The cleaning component and the roller brush cover are linked and cooperated.

[0009] The cleaning equipment has a working mode and a self-cleaning mode:

[0010] When the cleaning equipment is in working mode, the scraping component moves to the scraping position and can drive the roller brush cover away from the roller brush to form a set gap with the roller brush.

[0011] When the cleaning equipment is in self-cleaning mode, the cleaning equipment is located inside the base station. The scraping component moves to a clearance position and can drive the roller brush cover close to the roller brush and contact the bristles on the roller brush to achieve self-cleaning of the roller brush cover.

[0012] Beneficial effects: During normal cleaning operation, the cleaning equipment moves to a position where it is in an interference fit with the bristles of the roller brush, effectively cleaning the dirt on the bristles. After cleaning, the entire unit is placed on the base station and the self-cleaning mode is activated. The cleaning component moves to a position where it is in a clearance fit with the bristles of the roller brush, separating the cleaning component from the roller brush. This avoids the problem of bristle wear caused by the interference fit during self-cleaning mode. At the same time, due to the linkage between the cleaning component and the roller brush cover, the cleaning component can drive the roller brush cover to rotate closer to the roller brush when it moves to the clearance position, keeping the roller brush cover in close contact with the roller brush. At this time, controlling the forward and reverse rotation of the roller brush can achieve self-cleaning of the roller brush cover. This application links the scraping component with the roller brush cover. When the cleaning equipment performs self-cleaning, the scraping component can not only move to a avoidance position to avoid the roller brush, reducing friction between them, thus increasing the service life of the roller brush and reducing the frequency of replacement, but also drive the roller brush cover to a position where it contacts and adheres to the roller brush, thereby cleaning the dirt on the roller brush cover. Only one drive device is needed to control the movement of both the scraping component and the roller brush cover, saving control costs and simplifying control steps. This effectively solves the problem that related self-cleaning equipment requires separate drive mechanisms for the scraping component and the roller brush cover, resulting in a cumbersome control process and high costs.

[0013] In one alternative embodiment, the roller brush cover is rotatably mounted on the base, and the scraping assembly is provided with a linkage component.

[0014] The linkage component engages with the roller brush cover to limit the movement of the scraping assembly, thereby converting the motion of the roller brush cover into the power to rotate towards or away from the roller brush.

[0015] Beneficial effects: By using a linkage component on the scraping assembly that limits the movement between itself and the roller brush cover, when the scraping assembly moves to the avoidance position, the roller brush cover can rotate to a self-cleaning position that contacts and engages with the roller brush under the action of the linkage component, thus facilitating the cleaning of the roller brush cover by the roller brush; when the scraping assembly moves to the scraping position, the roller brush cover can rotate to the initial position that engages with the roller brush gap under the action of the linkage component and / or the reset component, thus effectively ensuring that there is a set gap between the roller brush cover and the roller brush when the cleaning equipment is performing normal cleaning work, and that it will not interfere with the movement of the roller brush.

[0016] In one optional embodiment, the roller brush cover includes a roller brush cover body and a connecting part. One end of the connecting part is fixed to the roller brush cover body, the other end is limited and engaged with the linkage component, and the middle part is rotatably connected to the base.

[0017] When the scraping assembly moves to the scraping position, the main body of the roller brush cover can rotate away from the roller brush under the action of the linkage component;

[0018] When the scraping assembly moves to the avoidance position, the linkage component can push the main body of the roller brush cover to rotate closer to the roller brush through the connecting part.

[0019] Beneficial effects: By adopting the above-mentioned connecting part design, the roller brush cover can achieve both a rotatable connection between the roller brush cover and the base, and a limiting cooperation with the linkage component to achieve linkage between the roller brush cover and the scraping assembly. This multi-functional design further simplifies the structure. Furthermore, by using a rotatable connection between the middle of the connecting part and the two ends cooperating with the roller brush cover body and the scraping assembly respectively, the entire roller brush cover forms a lever-like structure. This changes the direction of force, allowing the scraping assembly to push the connecting part upwards, thus driving the roller brush cover body downwards and pressing it tightly against the roller brush. This not only makes the position of the scraping assembly unrestricted, facilitating its installation layout, but also allows the scraping assembly to drive the roller brush cover more easily and effortlessly.

[0020] In one alternative embodiment, the linkage component is a push-up protrusion disposed on the scraping assembly, which abuts against the roller brush cover.

[0021] Beneficial effects: The linkage component adopts a push-up protrusion, which has a simple structure and is easy to process and form. The linkage between the scraping component and the roller brush cover is achieved by the push-up protrusion abutting and cooperating with the roller brush cover. Compared with the hinge or hook method, the linkage method is simpler and more reliable, and also facilitates disassembly, assembly and maintenance.

[0022] In one optional embodiment, two sets of connecting portions are provided at both ends of the main body of the roller brush along the axial direction of the roller brush.

[0023] There are two sets of linkage components, and the two sets of linkage components are matched one-to-one with the two sets of connecting parts.

[0024] Beneficial effects: By setting two sets of connecting parts at both ends of the main body of the roller brush cover, and two sets of corresponding linkage components, the two sets of linkage components and the two sets of connecting parts are in one-to-one contact and cooperation, thereby enabling the main body of the roller brush cover to be pushed from both sides, making the movement of the main body of the roller brush cover more balanced and stable.

[0025] In one alternative implementation, the roller brush assembly further includes:

[0026] The first rotating shaft, the connecting part is rotatably connected to the base through the first rotating shaft;

[0027] The first reset element, disposed on the first rotating shaft, is capable of applying a reset force to the main body of the roller brush cover, rotating it away from the roller brush.

[0028] Beneficial effects: The first reset component set on the first rotating shaft enables the roller brush cover to have a tendency to rotate away from the roller brush. When the scraping component moves to the scraping position and no longer presses down on the roller brush cover, the first reset component can give the roller brush cover body an upward reset force, so that the roller brush cover can automatically reset to the initial position that matches the gap with the roller brush, thereby effectively ensuring the normal operation of the cleaning work.

[0029] In one alternative embodiment, the scraping assembly is rotatably mounted on the base, and the cleaning device further includes:

[0030] A drive unit, connected to the scraping assembly, is used to drive the scraping assembly to rotate between a scraping position and an avoidance position.

[0031] Beneficial effects: The scraping component is rotatably mounted on the base. During normal cleaning and self-cleaning operations, the cleaning equipment can control the scraping component to rotate between the scraping position and the avoidance position via the drive device. This ensures the scraping performance of the component while also ensuring that the scraping component separates from the roller brush during the self-cleaning process, reducing friction between the scraping component and the roller brush and extending the service life of the roller brush.

[0032] In one alternative implementation, the driving device includes:

[0033] The power mechanism has an output shaft;

[0034] The transmission mechanism includes a drive gear and a driven gear. The drive gear is fixed on the output shaft, and the driven gear meshes between the drive gear and the scraping assembly.

[0035] The power mechanism drives the scraping assembly to rotate between the scraping position and the avoidance position via the driving gear and the driven gear.

[0036] Beneficial effects: The drive unit uses a drive gear and a driven gear as the transmission mechanism, which makes the transmission precise and reliable, enabling the scraping component to move precisely between the scraping position and the avoidance position.

[0037] In one alternative implementation, the power mechanism includes:

[0038] The drive motor has an output shaft;

[0039] The motor bracket is mounted on the motor bracket. The transmission mechanism also includes a gear cover, which is used to cooperate with the motor bracket to limit the driving gear and the driven gear between the motor bracket and the gear cover.

[0040] Beneficial effects: The gear cover can cooperate with the motor bracket to limit the driving gear and driven gear between them, thereby improving the stability of the driving gear and driven gear structure.

[0041] In one optional embodiment, the cleaning device further includes:

[0042] A position detection mechanism is used to issue corresponding trigger signals when the scraping assembly moves to the scraping position and the avoidance position.

[0043] Beneficial effects: The position detection mechanism enables precise control of the scraping component's position, ensuring accurate scraping stroke and preventing over- or under-movement of the scraping component between the scraping position and the avoidance position. This would affect the scraping cleaning effect of the scraping component on the roller brush, or prevent the scraping component from effectively separating from the roller brush in self-cleaning mode, resulting in continued wear on the bristles.

[0044] In one optional embodiment, the position detection mechanism includes a first position switch, a second position switch, and a trigger.

[0045] When the cleaning assembly moves to the cleaning position, the trigger can activate the first position switch;

[0046] When the scraping assembly moves to the avoidance position, the trigger can activate the second position switch.

[0047] Beneficial effects: When the cleaning equipment receives a cleaning command, the drive unit rotates the scraping assembly to the scraping position. At this point, the trigger activates the first position switch. Upon receiving the trigger signal from the first position switch, the cleaning equipment controls the drive unit to stop rotating the scraping assembly, keeping it in the scraping position. Then, the roller brush rotates at high speed, allowing the scraping assembly to clean the dirt on the roller brush, hanging it down and removing it through the suction mechanism, ensuring the scraping performance of the scraping assembly. When the entire unit is placed in a base station and receives a self-cleaning command, the drive unit drives the scraping assembly to rotate. When the device reaches the avoidance position, the trigger can activate the second position switch. When the cleaning device receives the trigger signal from the second position switch, it controls the drive device to stop driving the scraping component to rotate, so that the scraping component is kept in the avoidance position. At this time, the scraping component is disengaged from the roller brush to avoid friction. At the same time, the linkage component on the scraping component rotates upward, which will link the roller brush cover to rotate downward to the self-cleaning position where it contacts the bristles on the roller brush. At this time, there is a slight interference between the roller brush cover and the bristles. Then, the roller brush is controlled to rotate in both directions, and the bristles on the roller brush can achieve self-cleaning of the dirt on the roller brush cover.

[0048] In one alternative implementation, the scraping assembly includes:

[0049] The support is rotatably mounted on the base, and the support is provided with a linkage component for linkage with the roller brush cover;

[0050] The scraper is mounted on the support and has several scraping teeth for scraping dirt off the bristles of the roller brush.

[0051] Beneficial effects: By setting a linkage component on the support, the linkage between the scraping component and the roller brush cover can be realized. During the self-cleaning process, the roller brush cover can rotate downward under the linkage of the linkage component, which makes it easier for the bristles on the roller brush to clean the dirt on the scraping component. This improves the cleaning effect and eliminates the need for a separate drive mechanism to drive the roller brush cover, simplifying the structure and control steps and saving control costs.

[0052] Secondly, this utility model provides a cleaning system, including a base station and a cleaning device according to any of the above embodiments. Attached Figure Description

[0084] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0085] Existing cleaning equipment typically uses a comb-shaped scraper fixed to one side of the roller brush to achieve cleaning with the roller brush, or a floating comb-shaped scraper pushed by a spring. This allows the scraper to remove dirt from the roller brush as it rotates at high speed. To achieve the desired cleaning effect, the scraper and roller brush need an interference fit to effectively remove dirt. However, under the drive of the roller brush motor, this interference fit over time easily causes wear on the brush bristles. As a result, after prolonged use, the bristles gradually shorten, the gap between the scraper and the roller brush increases, and the cleaning effect gradually decreases.

[0086] When cleaning equipment is working normally, it mainly uses the rotation of a roller brush to remove sewage and garbage from the ground. However, the rotation of the roller brush can cause garbage to be picked up and flung around, and the water spray mechanism of the floor brush can also cause water splashing. Therefore, a roller brush cover is usually installed to prevent garbage from being flung out and water from splashing. Since the main function of the roller brush cover is to shield against flung garbage and splashing water, it can easily accumulate garbage and sewage. Therefore, the roller brush cover needs to be cleaned regularly. If it is not cleaned for a long time, bacteria will grow on the roller brush cover, and unpleasant odors will develop.

[0087] During the self-cleaning process of the cleaning equipment on the base station, it is necessary to first control the roller brush cover to move to the set self-cleaning position so that the bristles on the roller brush can contact the roller brush cover. Then, the roller brush is controlled to rotate forward and backward to scrape off the dirt on the roller brush cover, thus achieving self-cleaning of the cleaning equipment. The entire control process is relatively cumbersome and costly. However, the self-cleaning process does not require a toothed scraper to clean the dirt on the roller brush. Fixed or floating scrapers cannot effectively avoid the roller brush, resulting in prolonged friction between the scraper and the roller brush. This causes the bristles on the roller brush to shorten due to prolonged friction, reducing their lifespan. Furthermore, the gap between the scraper and the roller brush increases, reducing the cleaning effect and ultimately affecting the cleaning performance over time.

[0088] Currently, the industry standard for addressing the issue of easily worn roller brushes in cleaning equipment and their gradually deteriorating cleaning performance is primarily to replace the roller brushes. This method involves frequent brush replacements and incurs high costs. Furthermore, existing self-cleaning equipment requires a separate drive mechanism to move the roller brush cover, making the control process cumbersome, costly, and hindering product adoption and promotion.

[0089] The following is combined with Figures 1 to 20 The following describes embodiments of the present invention.

[0090] According to an embodiment of the present invention, in one aspect, the present invention provides a cleaning device 100, including a base 10, a roller brush assembly 20, and a scraping assembly 30. The roller brush assembly 20 includes a roller brush 21 and a roller brush cover 22, the roller brush cover 22 being movably disposed on the base 10; the scraping assembly 30 is movably disposed on the base 10, and the scraping assembly 30 can move between a scraping position that is interference-fitted with the roller brush 21 and a clearance position that is loosely fitted with the roller brush 21, and the scraping assembly 30 and the roller brush cover 22 are linked together. The cleaning device 100 has a working mode and a self-cleaning mode: When the cleaning device 100 is in the working mode, the scraping component 30 moves to the scraping position and can drive the roller brush cover 22 away from the roller brush 21 and form a set gap with the roller brush 21; when the cleaning device 100 is in the self-cleaning mode, the cleaning device 100 is located inside the base station 200, the scraping component 30 moves to the avoidance position and can drive the roller brush cover 22 close to the roller brush 21 and contact the bristles on the roller brush 21 to achieve self-cleaning of the roller brush cover 22.

[0091] In the above embodiment, when the cleaning device 100 is performing normal cleaning work, the scraping component 30 moves to the scraping position where it is in interference fit with the bristles of the roller brush 21, which can effectively clean the dirt on the bristles. After the cleaning work is completed, the whole device is placed on the base station 200 and the self-cleaning mode is activated. The scraping component 30 moves to the avoidance position where it is in inter-partition fit with the bristles of the roller brush 21, so that the scraping component 30 and the roller brush 21 are separated, avoiding the problem of wear of the bristles due to interference fit during the self-cleaning mode. At the same time, since the scraping component 30 and the roller brush cover 22 are linked, when the scraping component 30 moves to the avoidance position, it can drive the roller brush cover 22 to rotate closer to the roller brush 21, so that the roller brush cover 22 and the roller brush 21 are kept in close contact. At this time, controlling the forward and reverse rotation of the roller brush 21 can realize the self-cleaning of the roller brush cover 22. This application links the scraping component 30 with the roller brush cover 22. When the cleaning device 100 performs self-cleaning, the scraping component 30 can not only move to a clearance position to avoid the roller brush 21, reducing friction between them, thus improving the service life of the roller brush 21 and reducing its replacement frequency, but also drive the roller brush cover 22 to a position where it contacts and adheres to the roller brush 21, thereby cleaning the dirt on the roller brush cover 22. Only one drive device 40 is needed to control the movement of both the scraping component 30 and the roller brush cover 22, saving control costs, simplifying control steps, and effectively solving the problem that the self-cleaning device 100 in related technologies requires a separate drive mechanism for the scraping component 30 and the roller brush cover 22, resulting in a cumbersome control process and high costs.

[0092] In this embodiment, the roller brush cover 22 is located above the roller brush 21. The roller brush cover 22 and the scraping component 30 can be driven by a linkage mechanism or directly contacted to achieve linkage. When the cleaning equipment 100 is performing normal cleaning work, the roller brush 21 rotates at high speed, and the scraping component 30 is in a scraping position with an interference fit with the bristles of the roller brush 21, which can promptly scrape off the dirt on the bristles. At this time, there is a set gap between the roller brush cover 22 and the roller brush 21, and the dirt on the roller brush 21 that has not been scraped off by the scraping component 30 can be thrown onto the roller brush cover 22 under the action of centrifugal force. When the cleaning device 100 completes the cleaning work, it is placed in the base station 200. At this time, since the roller brush 21 no longer performs cleaning work, the scraping component 30 does not need to clean the roller brush 21. The scraping component 30 moves to a position that avoids the gap between the brush bristles of the roller brush 21. At this time, the roller brush cover 22 rotates downward under the linkage of the scraping component 30 and keeps in close contact with the roller brush 21. Then, by controlling the forward and reverse rotation of the roller brush 21, the dirt attached to the roller brush cover 22 is self-cleaned.

[0093] In some embodiments, the roller brush cover 22 is rotatably disposed on the base 10, and the scraping assembly 30 is provided with a linkage component 301; the linkage component 301 is limited to the roller brush cover 22 to convert the movement of the scraping assembly 30 into the power for the roller brush cover 22 to rotate toward or away from the roller brush 21.

[0094] In the above embodiments, by means of a linkage component provided on the scraping assembly that limits the movement between itself and the roller brush cover, when the scraping assembly moves to the avoidance position, the roller brush cover can rotate to a self-cleaning position that contacts and engages with the roller brush under the drive of the linkage component, thereby facilitating the cleaning of the roller brush cover by the roller brush; when the scraping assembly moves to the scraping position, the roller brush cover can rotate to an initial position that engages with the roller brush gap under the drive of the linkage component and / or the action of the reset component, thereby effectively ensuring that when the cleaning equipment 100 is performing normal cleaning work, there is a set gap between the roller brush cover and the roller brush, and it will not interfere with the movement of the roller brush.

[0095] Specifically, when the scraping assembly moves to the avoidance position, the linkage component converts the movement of the scraping assembly into downward pressure applied to the roller brush cover, causing the roller brush cover and the roller brush to contact and engage. The limiting engagement between the linkage component and the roller brush cover includes, but is not limited to, hinges, hooks, and abutments. For example, the linkage component can adopt structural forms such as hinge seats, pull rings, hooks, and protrusions.

[0096] In some embodiments, the roller brush cover 22 includes a roller brush cover body 221 and a connecting portion 222; one end of the connecting portion 222 is fixed to the roller brush cover body 221, the other end is limitedly engaged with the linkage component 301, and the middle part is rotatably connected to the base 10; when the scraping component 30 moves to the scraping position, the roller brush cover body 221 can rotate away from the roller brush 21 under the drive of the linkage component 301; when the scraping component 30 moves to the avoidance position, the linkage component 301 can push the roller brush cover body 221 to rotate closer to the roller brush 21 through the connecting portion 222.

[0097] In the above embodiments, the roller brush cover 22, through the design of the connecting part 222, can both achieve a rotatable connection between the roller brush cover 22 and the base 10, and can also cooperate with the linkage component 301 to achieve linkage between the roller brush cover 22 and the scraping component 30, thus achieving multiple functions and further simplifying the structure. In addition, by adopting a method in which the connecting part 222 is rotatably connected to the base in the middle and cooperates with the roller brush cover body and the scraping component at both ends respectively, the entire roller brush cover 22 forms a lever-like structure, which can change the direction of force. This allows the scraping component to drive the roller brush cover body to move downward and fit tightly against the roller brush when pushing the connecting part upward. This not only makes the position of the scraping component unrestricted and facilitates the installation layout of the scraping component, but also makes it easier and less strenuous for the scraping component to drive the roller brush cover.

[0098] Specifically, the main body 221 of the roller brush cover is an arc-shaped plate structure, and the middle part of the connecting part 222 is provided with a first shaft hole. The first shaft hole and the base 10 are connected by a first rotating shaft 23 to realize the rotational connection between the roller brush cover 22 and the base 10. Of course, in other alternative embodiments, the middle part of the connecting part 222 can be integrally formed with the first rotating shaft 23.

[0099] When the cleaning equipment 100 is performing normal cleaning work, the scraping component 30 moves to the scraping position. At this time, the roller brush cover body 221 can rotate away from the roller brush 21 under the drive of the linkage component 301, so as to avoid interfering with the high-speed rotating roller brush 21. When the cleaning equipment 100 performs self-cleaning, the scraping component 30 moves to the avoidance position. At this time, the linkage component 301 can push the roller brush cover body 221 to rotate closer to the roller brush 21 through the connecting part 222, so that the roller brush cover body 221 and the bristles of the roller brush 21 come into contact and cooperate. At this time, the dirt on the inner wall of the roller brush cover body 221 can be cleaned by controlling the forward and reverse rotation of the roller brush 21.

[0100] In some embodiments, combined with Figures 18 to 20 As shown, the linkage component 301 is a push-up protrusion provided on the scraping assembly 30, and the push-up protrusion abuts against the roller brush cover.

[0101] In the above embodiments, the linkage component 301 adopts a push-up protrusion, which has a simple structure and is easy to process and form. The linkage between the scraping component and the roller brush cover is achieved by the push-up protrusion abutting and cooperating with the roller brush cover. Compared with the hinge or hook method, the linkage method is simpler and more reliable, and it is also convenient for disassembly, assembly and subsequent maintenance.

[0102] Furthermore, the main body 221 of the roller brush cover has an inner sidewall facing the roller brush 21 and an outer sidewall facing away from it. The connecting part 222 is a connecting rib fixedly provided on the outer sidewall, and the connecting rib abuts against the push protrusion. The connecting part 222, by adopting the form of a connecting rib fixedly provided on the outer sidewall of the main body 221 of the roller brush cover, has a simple structure and is easy to process and form.

[0103] Specifically, the linkage component 301 is a protrusion fixedly mounted on the scraping assembly 30. The connecting rib includes a shaft portion located in the middle and a first arm and a second arm portion arranged at a set angle on both sides of the shaft portion. A shaft hole is provided in the shaft portion. The end of the first arm portion is fixed on the outer wall of the roller brush cover body 221. The end of the second arm portion is constructed as an abutting end suitable for abutting and cooperating with the linkage component 301.

[0104] In some embodiments, along the axial direction of the roller brush 21, two sets of connecting portions 222 are provided at both ends of the roller brush cover body 221; two sets of linkage components 301 are provided accordingly, and the two sets of linkage components 301 and the two sets of connecting portions 222 are matched one-to-one.

[0105] In the above embodiment, by providing two sets of connecting portions 222 at both ends of the roller brush cover body 221 and two sets of corresponding linkage components 301, the two sets of linkage components 301 and the two sets of connecting portions 222 are in one-to-one contact and cooperation, thereby enabling the roller brush cover body 221 to be pushed from both sides, making the movement of the roller brush cover body 221 more balanced and stable.

[0106] In some embodiments, the roller brush assembly 20 further includes a first rotating shaft 23 and a first reset member 24. The connecting part 222 is rotatably connected to the base 10 via the first rotating shaft 23. The first reset member 24 is disposed on the first rotating shaft 23 and can apply a reset force to the roller brush cover body 221 in a direction away from the roller brush 21.

[0107] In the above embodiment, the first reset member provided on the first rotating shaft enables the roller brush cover to have a tendency to rotate away from the roller brush. When the scraping component moves to the scraping position and no longer presses down on the roller brush cover, the first reset member can give the roller brush cover body an upward reset force, so that the roller brush cover can automatically reset to the initial position that matches the gap with the roller brush, thereby effectively ensuring the normal operation of the cleaning work.

[0108] Preferably, the first reset member 24 is a torsion spring, which is sleeved on the first rotating shaft 23. The two ends of the torsion spring abut against the roller brush cover body 221 and the base 10 respectively. When the push-up protrusion does not push up the connecting part and presses down on the roller brush cover body, the torsion spring can give the roller brush cover body an upward reset force, so that the gap between the roller brush cover body and the roller brush is restored, so as to carry out normal cleaning work.

[0109] Of course, in other alternative implementations, the first reset member 24 may also be a tension spring, and this embodiment does not limit this.

[0110] In this embodiment, along the circumferential direction of the roller brush cover body 221, the connection position between the connecting rib and the roller brush cover body 221 is located on one side of the arc-shaped roller brush cover body 221. When the scraping component 30 moves to the avoidance position, the linkage component 301 moves upward, pushing the second arm of the connecting rib to rotate upward. Under the action of the lever, the first arm of the connecting rib drives the roller brush cover body 221 to rotate downward, pressing down the roller brush cover body 221, so that the roller brush cover body 221 and the roller brush 21 come into contact and cooperate. When the scraping component 30 moves to the scraping position, the linkage component 301 moves upward, and the second arm falls down under the action of the first reset component 24. Under the action of the lever, the first arm drives the roller brush cover body 221 to rotate upward, lifting the roller brush cover body 221, so that the roller brush cover body 221 and the roller brush 21 disengage from contact and form a set gap.

[0111] In some embodiments, the roller brush assembly 20 further includes a sealing strip 25, which is disposed on the inner edge of the roller brush cover body 221. The sealing strip 25 enables a sealed fit between the roller brush cover body 221 and the middle cover plate 13 of the base 10, preventing dirt from being thrown from between the roller brush cover body 221 and the middle cover plate 13 of the base 10 to other positions inside the base 10, thus affecting the hygiene of the entire machine.

[0112] In some embodiments, the scraping assembly 30 is rotatably mounted on the base 10, and the cleaning device 100 further includes a drive device 40 connected to the scraping assembly 30 for driving the scraping assembly 30 to rotate between a scraping position and an avoidance position.

[0113] In the above embodiment, the scraping component 30 is rotatably mounted on the base 10. When the cleaning device 100 is performing normal cleaning and self-cleaning work, the scraping component 30 can be controlled to rotate between the scraping position and the avoidance position by the drive device 40. In this way, while ensuring the scraping performance of the scraping component 30, it can also ensure that the scraping component 30 is separated from the roller brush 21 during the self-cleaning process, thereby reducing the friction between the scraping component 30 and the roller brush 21 and improving the service life of the roller brush 21.

[0114] Of course, in other alternative embodiments, the scraping component 30 can also be slidably disposed on the base 10. For example, the scraping component 30 can be laterally disposed within the base 10. The scraping component 30 can be driven by a drive mechanism to move between the scraping position and the avoidance position. The linkage component 301 and the connection part 222 of the roller brush cover 22 can be linked by an inclined surface engagement.

[0115] In some embodiments, the drive device 40 includes a power mechanism 41 and a transmission mechanism 42. The power mechanism 41 has an output shaft, and the transmission mechanism 42 includes a drive gear 421 and a driven gear 422. The drive gear 421 is fixed on the output shaft, and the driven gear 422 meshes between the drive gear 421 and the scraping assembly 30. The power mechanism 41 drives the scraping assembly 30 to rotate between a scraping position and a clearance position through the drive gear 421 and the driven gear 422.

[0116] In the above embodiments, the drive device 40 uses a drive gear 421 and a driven gear 422 as a transmission mechanism 42, which provides precise and reliable transmission, enabling the scraping component 30 to move precisely between the scraping position and the avoidance position.

[0117] In some embodiments, the power mechanism 41 includes a drive motor 411 and a motor bracket 412. The drive motor 411 has an output shaft. The drive motor 411 is mounted on the motor bracket 412. The transmission mechanism 42 also includes a gear cover 43, which cooperates with the motor bracket 412 to limit the driving gear 421 and the driven gear 422 between itself and the motor bracket 412.

[0118] In the above embodiment, the gear cover 43 can cooperate with the motor bracket 412 to limit the driving gear 421 and the driven gear 422 between them, thereby improving the stability of the driving gear and driven gear structure.

[0119] Specifically, the motor bracket 412 includes a motor housing and a gear mounting portion. The gear mounting portion includes a mounting plate fixedly disposed on one side of the motor housing. A connecting shaft for mounting a driven gear 422 is fixedly disposed on the mounting plate. The driven gear 422 is rotatably mounted on the connecting shaft. The mounting plate also has an opening for the output shaft of the drive motor 411 to extend through. The output shaft of the drive motor 411 extends through the opening and is connected and fixed to the driving gear 421. Bolt posts are provided on the motor bracket 412, and the gear cover 43 is fixed to the bolt posts of the motor bracket 412 by screws 46.

[0120] Furthermore, the drive device 40 also includes a motor bracket cover 413. The motor bracket 412 is provided with a mounting groove for accommodating the drive motor 411. The mounting groove is open at the top. The motor bracket cover 413 is detachably installed and fixed at the opening of the mounting groove, sealing the drive motor 411 inside the mounting groove.

[0121] In some embodiments, the cleaning device 100 further includes a position detection mechanism, which is used to issue corresponding trigger signals when the scraping assembly moves to the scraping position and the avoidance position.

[0122] In the above embodiments, the position detection mechanism can accurately control the position of the scraping component, ensure the accuracy of the scraping stroke, and avoid the scraping component moving too much or too little when moving between the scraping position and the avoidance position, thereby affecting the scraping cleaning effect of the scraping component on the roller brush, or the scraping component and the roller brush not being able to separate effectively in the self-cleaning mode, and the brush bristles still having wear problems.

[0123] Alternatively, the position detection mechanism can take the form of a distance sensor, photoelectric sensor, infrared sensor, position switch, etc. The position detection mechanism can be mounted on the drive unit, the scraping assembly, or the base.

[0124] In some embodiments, the position detection mechanism includes a first position switch, a second position switch, and a trigger; when the scraping assembly moves to the scraping position, the trigger can trigger the first position switch; when the scraping assembly moves to the avoidance position, the trigger can trigger the second position switch.

[0125] In the above embodiment, when the cleaning device 100 receives a cleaning command, the drive device 40 drives the scraping assembly 30 to rotate to the scraping position. The trigger 4211 can then trigger the first position switch 44. Upon receiving the trigger signal from the first position switch 44, the cleaning device 100 controls the drive device 40 to stop driving the scraping assembly 30 to rotate, keeping the scraping assembly 30 in the scraping position. At this time, the roller brush 21 is controlled to rotate at high speed, allowing the scraping assembly 30 to clean the dirt on the roller brush 21, hanging the dirt down and sucking it away by the suction mechanism, thus ensuring the scraping performance of the scraping assembly 30. When the entire device is placed in the base station and receives a self-cleaning command, the drive device 40 drives the scraping assembly 30 to rotate to the scraping position. When in the avoidance position, the trigger 4211 can trigger the second position switch 45. When the cleaning device 100 receives the trigger signal from the second position switch 45, it controls the drive device 40 to stop driving the scraping assembly 30 to rotate, so that the scraping assembly 30 is kept in the avoidance position. At this time, the scraping assembly 30 is disengaged from the roller brush 21 to avoid friction. At the same time, the linkage component 301 on the scraping assembly 30 rotates upward, which links the roller brush cover 22, so that the roller brush cover 22 rotates downward to the self-cleaning position where it contacts the bristles on the roller brush 21. At this time, there is a slight interference between the roller brush cover 22 and the bristles. Then, the roller brush 21 is controlled to rotate in both directions, and the bristles on the roller brush 21 can achieve self-cleaning of the dirt on the roller brush cover 22.

[0126] Optionally, the trigger is located on the scraping assembly or the drive unit, and the first position switch and the second position switch are located on the side wall of the base or the drive unit.

[0127] In some specific embodiments, the first position switch 44 and the second position switch 45 are disposed on the gear cover 43, and the trigger 4211 is disposed on the drive gear 421. By disposing of the first position switch 44 and the second position switch 45 on the gear cover, compared to disposing them on the motor bracket, more installation space is available, making assembly and maintenance of the first position switch 44 and the second position switch 45 more convenient. By disposing the trigger on the drive gear, compared to disposing it on the driven gear, the rotational speed of the drive motor can be directly fed back without conversion, resulting in a more timely response and more precise and efficient control.

[0128] Of course, in other alternative embodiments, the first position switch 44 and the second position switch 45 can also be disposed on the housing of the base or the motor bracket, and the trigger 4211 can also be disposed on the driven gear or the scraping assembly. In this embodiment, the specific positions of the first position switch 44, the second position switch 45 and the trigger 4211 are not limited.

[0129] Furthermore, the gear cover 43 is provided with mounting posts for mounting the first position switch 44 and the second position switch 45. The gear cover 43 is provided with two sets of mounting posts, and the two sets of mounting posts are used to install the two position switches respectively. Each set of mounting posts includes two mounting posts spaced apart. Each position switch is provided with two mounting through holes. The position switch is sleeved on the mounting post through the two mounting through holes. By using the above method to install the first position switch 44 and the second position switch 45, not only can the stability of the structure of the first position switch 44 and the second position switch 45 be guaranteed, but it is also convenient to disassemble and assemble. When you want to disassemble, you can simply remove the position switch from the mounting post. When installing, you can simply sleeve it on the mounting post.

[0130] Optionally, the first position switch 44 and the second position switch 45 are mechanical switches. Preferably, the first position switch 44 and the second position switch 45 are micro switches. When the drive gear 421 rotates, it drives the trigger element 4211 to move along a predetermined arc trajectory. The first position switch 44 and the second position switch 45 are arranged at intervals along this arc trajectory on the gear cover 43. A trigger part is provided on each of the two inner sides of the first position switch 44 and the second position switch 45. When the trigger element 4211 moves under the drive of the drive gear 421, it can trigger the trigger part, thereby triggering the first position switch 44 and the second position switch 45. Preferably, the trigger part is a trigger spring.

[0131] In this embodiment, the assembly process of the floor brush of the drive device 40 is as follows: the drive motor 411 is placed in the mounting slot of the motor bracket 412, the motor bracket cover 413 is fastened to the slot of the motor bracket 412, the drive gear 421 is installed into the output shaft of the drive motor 411, the support ring 414 is put onto the output shaft to press down the drive gear 421, then the driven gear 422 is installed into the motor bracket 412, and the driven gear 422 is pressed down by the gear cover 43 and the motor bracket 412. Then the gear cover 43 is fixed to the motor bracket 412 with screws 46, and the first position switch 44 and the second position switch 45 are assembled on the gear cover 43. The entire drive device 40 is then assembled.

[0132] Optionally, the base 10 includes an upper housing 11, a lower housing 12, and a middle cover plate 13 disposed between the upper housing 11 and the lower housing 12. The middle cover plate 13 and the lower housing 12 enclose an installation space for the drive device 40 to be installed. The drive device 40 is fixed on the lower housing 12.

[0133] In some embodiments, the first position switch 44 and the second position switch 45 are disposed on the side wall of the gear cover 43 away from the driving gear 421 and the driven gear 422; the trigger 4211 is a trigger rod fixedly disposed on the driving gear 421, and the gear cover 43 is provided with an opening through which the trigger rod can pass and avoid the movement of the trigger rod.

[0134] In the above embodiment, the first position switch 44 and the second position switch 45 are disposed on the outer wall of the gear cover 43 to avoid interfering with the movement of the driving gear 421 and the driven gear 422. The trigger member 4211 adopts the structure of a trigger rod, which is simple in structure and easy to process and form. The opening in the gear cover 43 allows the trigger rod to pass through and avoids the movement of the trigger rod, which facilitates the trigger rod to engage with the first position switch 44 and the second position switch 45.

[0135] Specifically, the trigger rod is fixedly mounted on the outer periphery of the gear cover 43, and the opening on the gear cover 43 is an arc-shaped opening, allowing the trigger rod to move in an arc-shaped trajectory within the opening. By mounting the first position switch 44 and the second position switch 45 on the gear cover 43, the overall structure can be made more compact, improving space utilization.

[0136] In some embodiments, the scraping assembly 30 includes a support 31 and a scraper 32. The support 31 is rotatably mounted on the base 10. The support 31 is provided with a linkage component 301 for linkage with the roller brush cover 22. The support 31 is also provided with a meshing part 310 for meshing with the driven gear 422. The scraper 32 is mounted on the support 31 and is provided with a plurality of scraping teeth for scraping dirt off the bristles of the roller brush 21.

[0137] In the above embodiment, the meshing part 310 provided on the support 31 can be used to drive the entire scraping assembly 30 to rotate between the scraping position and the avoidance position by meshing transmission between the meshing part 310 and the driven gear 422. The linkage part 301 provided on the support 31 can realize the linkage between the scraping assembly 30 and the roller brush cover 22, so that during the self-cleaning process, the roller brush cover 22 can rotate downward under the linkage of the linkage part 301, thereby facilitating the bristles on the roller brush 21 to clean the dirt on the scraping assembly 30, improving the cleaning effect, and eliminating the need to set a separate drive mechanism to drive the roller brush cover 22 to move, simplifying the structure and control steps, and saving control costs.

[0138] Specifically, two second rotating shafts are fixedly installed on both sides of the support 31, and rotating bushings 313 are rotatably fitted on the two second rotating shafts. The rotating bushings 313 are connected to the base 10, thereby realizing the rotatable connection between the support 31 and the base 10. The meshing part 310 is a sector gear fixedly installed on the support 31. Preferably, the meshing part 310 and the support 31 are integrally formed. The scraper 32 is screwed to the support 31 for easy disassembly and assembly. The scraper 32 has several scraping teeth on the edge near the roller brush 21, which can scrape off dirt on the bristles.

[0139] Furthermore, the scraping assembly 30 also includes a second reset member 314, a baffle plate 33, and a pressure plate 34. The second reset member 314 is mounted on the support 31 and applies a rotational force to the entire scraping assembly 30 towards the scraping position. The second reset member 314 applies a force to the scraper blade towards the roller brush, preventing the scraping assembly 30 from rotating arbitrarily and becoming unstable due to its high flexibility. The support 31 has two mounting shafts at both ends, and the second reset member 314 is correspondingly mounted on the two mounting shafts. Preferably, the second reset member 314 is a torsion spring sleeved on the mounting shaft, with both ends of the torsion spring abutting against the support 31 and the base 10, respectively. Of course, in other alternative embodiments, the second reset member 314 can also adopt a structure such as a compression spring; this embodiment does not limit this.

[0140] Furthermore, the support 31 includes a front cover 311 and a rear cover 312. The engaging part 310, the linkage part 301, the second rotating shaft, and the mounting shaft are all formed on the rear cover 312. The rear cover 312 is provided with mounting holes for mounting the scraper 32. The assembly process of the scraping assembly 30 is as follows: First, the front cover 311 and the rear cover 312 are glued together to prevent water leakage. Then, the two rotating bushings 313 are respectively fitted onto the two second rotating shafts at both ends of the rear cover 312. Then, the two second reset parts 314 are respectively fitted onto the mounting shafts at both ends of the rear cover 312. Then, the scraper 32 is assembled into the corresponding mounting hole of the rear cover 312. Then, the baffle plate 33 is pressed onto the scraper 32. Then, the pressure plate 34 is pressed onto the baffle plate 33 and fixed with four screws.

[0141] In some embodiments, such as Figure 2 As shown, the cleaning device 100 includes a floor brush, a body connected to the floor brush, and a handle connected to the body. The floor brush includes the aforementioned base 10, roller brush assembly 20, scraping assembly 30, drive device 40, etc.

[0142] Preferably, in this embodiment, the cleaning equipment 100 is a floor scrubber.

[0143] The assembly steps, working process, and control method of the cleaning equipment 100 of this embodiment will be described below with reference to the accompanying drawings.

[0144] 1. The assembly process of cleaning equipment 100 is as follows:

[0145] The drive unit 40 is fixed to the lower housing 12 of the base 10 with screws; the meshing part 310 of the scraping assembly 30 is meshed with the driven gear 422 of the drive unit 40 and assembled at the front end of the lower housing 12; then the middle cover plate 13 is used to press down the scraping assembly 30; then the roller brush 21 is installed at the front end of the scraping assembly 30; then the roller brush cover 22 is installed on top of the roller brush 21 to cover the roller brush 21 and the scraper 32. The floor brush of the cleaning equipment 100 is now assembled.

[0146] 2. The working process of cleaning equipment 100 is as follows:

[0147] When the cleaning equipment 100 is cleaning the floor normally, the drive motor 411 drives the scraping component 30 to rotate and move forward. After reaching the scraping position, the scraper 32 can effectively clean the dirt. After cleaning, the whole machine is placed on the base station 200 and the self-cleaning mode is activated. At this time, the drive motor 411 drives the active gear 421 and the driven gear 422 to move, causing the scraping component 30 to rotate and move backward to the avoidance position, so that the scraper 32 separates from the roller brush 21 and avoids interference. At the same time, the linkage component 301 on the scraping component 30 moves, causing the roller brush cover 22 to rotate downward and keep in close contact with the roller brush 21. At this time, the roller brush 21 self-cleans in both forward and reverse directions. The scraping component 30 moves to the avoidance position, which can not only avoid the roller brush 21 and avoid friction between the scraper 32 and the roller brush 21, thus improving the service life of the roller brush 21, but also make the roller brush cover 22 fit with the roller brush 21, thus cleaning the dirt on the roller brush cover 22.

[0148] Furthermore, during the floor cleaning process of the cleaning equipment 100, the drive motor 411 drives the drive gear 421, which in turn drives the driven gear 422. The driven gear 422 drives the scraper 32 to rotate forward and contact the roller brush 21 through the meshing part 310 on the scraping assembly 30 (due to limited space, only a limited meshing part of the gear is left, so the meshing part 310 is made into a sector gear). When the trigger 4211 on the drive gear 421 touches the first position switch 44, the drive motor 411 stops moving, and the scraper 32 rotates to the foremost position. At this time, the roller brush 21 will rotate at high speed, and the scraper 32 will clean the dirt on the roller brush 21, scraping off the dirt, and then sucking it away through the suction chamber.

[0149] After the floor scrubber finishes cleaning the floor, it is placed in the base station 200. Upon receiving the self-cleaning command, the drive motor 411 drives the scraper 32 to rotate backward through the transmission mechanism 42. When the trigger 4211 on the drive gear 421 touches the second position switch 45, the drive motor 411 stops rotating backward. At this time, the scraper rotates to the last end, the scraper 32 disengages from the roller brush 21, and the scraper 32 maintains a gap with the brush bristles, thus enabling self-cleaning. At the same time, the linkage component 301 on the scraper 32 rotates upward, which in turn links the roller brush cover 22, causing the roller brush cover 22 to rotate downward, so that the roller brush cover 22 and the brush bristles on the roller brush 21 have a slight interference fit. After the roller brush starts to rotate, the brush bristles can clean the dirt on the roller brush cover 22.

[0150] The cleaning device 100 provided in this embodiment mainly improves the scraping function of the scraper 32 and the lifespan of the roller brush 21. While ensuring the scraping performance of the scraper 32, in order to increase the lifespan of the roller brush 21, the scraper 32 is controlled to disengage from the roller brush 21 during the self-cleaning process to reduce the friction between the scraper 32 and the roller brush 21. Through the linkage between the scraping component 30 and the roller brush cover 22, the cleaning function of the roller brush cover 22 can also be realized, thereby improving the lifespan of the roller brush 21. At the same time, the dirt on the roller brush cover 22 is also cleaned simultaneously, realizing the self-cleaning of the dirt on the roller brush cover 22, improving the lifespan of the roller brush 21 and the overall cleaning effect of the machine.

[0151] 3. The control method for cleaning equipment 100 is as follows:

[0152] Step A, working mode, including smart mode or powerful mode, allows users to choose whether or not to clean according to their own judgment;

[0153] Step B, self-cleaning mode; its function is for users to choose whether or not self-cleaning is needed based on their own judgment.

[0154] More detailed steps, step A, Smart Mode or Powerful Mode:

[0155] Step A-① Drive motor 411 to rotate forward, driving the entire scraping assembly to rotate forward 30;

[0156] During the forward rotation of step A-②, the machine determines whether the first position switch 44 is closed. If it is closed, continue to step A-③; if it is not closed, drive motor 411 continues to run until it closes within the specified time t, then continue to step A-③. If it does not close, then jump directly to step A-⑦.

[0157] After the first position switch is closed in step A-③, the drive motor 411 will no longer run;

[0158] Step A-④ The roller brush motor drives the roller brush 21 to rotate and begin cleaning;

[0159] Step A-⑤: Set the continuous operation time.

[0160] Step A-⑥ determines whether the user has selected to stop the machine; if "yes", proceed to step A-⑦; if "no", return to the working mode selection.

[0161] Step A-⑦ Cleaning equipment 100 stops.

[0162] More detailed steps, step B, self-cleaning mode:

[0163] Step B-① Drive motor 411 to rotate forward, driving the entire structure to rotate in reverse;

[0164] During the reversal process of step B-②, the machine determines whether the second position switch is closed. If it is closed, continue to B-③; if it is not closed, drive motor 411 continues to run until it closes within the specified time t, then continue to B-③; if it does not close, then directly jump to A-⑦.

[0165] After the second position switch is closed in step B-③, the drive motor 411 will no longer run;

[0166] Step B-④ The roller brush motor drives the roller brush 21 to rotate forward and backward to start self-cleaning;

[0167] Step A-⑤: Set the continuous operation time.

[0168] Step A-⑥ determines whether the user has selected to stop the machine; if "yes", proceed to A-⑦; if "no", return to the working mode selection.

[0169] Step A-⑦ Cleaning equipment 100 stops.

[0170] It should be noted that the control method proposed in this embodiment is based on the automatic oscillating scraper function of the floor scrubber. In addition to being applied to this product, the control logic can also be applied to other product series that are based on the same principle.

[0171] The cleaning device 100 provided in this embodiment can effectively scrape dirt in conjunction with the roller brush 21 during the cleaning process, depending on the cleaning status. During self-cleaning, the scraper 32 is disengaged from the roller brush 21 by the drive motor 411, reducing friction between the scraper 32 and the roller brush 21, increasing the service life of the roller brush 21, reducing the replacement frequency of the roller brush 21, and improving the user experience. During self-cleaning, the drive motor 411 drives the scraper 32 to rotate to an avoidance position, and through the linkage between the dirt scraping component 30 and the roller brush cover 22, the roller brush cover 22 can be rotated downwards. At this time, the bristles on the roller brush 21 will clean the dirt on the roller brush cover 22, achieving effective cleaning of the roller brush cover 22 and improving the overall cleaning effect of the machine.

[0172] According to an embodiment of the present invention, in another aspect, the present invention provides a cleaning system, including a base station 200 and a cleaning device 100 of any of the above embodiments.

[0173] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
