Description

Technical Field

[0001] The present invention relates to the field of smart home technology, and in particular to cleaning equipment and a cleaning system. Background Art

[0002] With the development of social economy and people's higher and higher requirements for home environment, cleaning equipment integrating floor washing, mopping and vacuuming has come into being and is widely used in people's lives. In order to improve the convenience of using cleaning equipment, cleaning equipment is generally automatically charged and self-cleaned through base stations.

[0003] The cleaning equipment in the related art includes a roller brush, a roller brush cover and a comb-tooth scraper. When the cleaning equipment is performing normal floor cleaning work, the roller brush rotates at high speed and the comb-tooth scraper can scrape off the dirt attached to the roller brush. However, the existing cleaning equipment has problems such as the bristles of the roller brush are easy to wear, the cleaning effect gradually deteriorates in the later stage, the self-cleaning process control process is cumbersome, the cost is high, and it is not conducive to the use and promotion of the product. Summary of the invention

[0004] In view of this, the present invention provides a cleaning device and a cleaning system to solve the problems in the prior art of cleaning devices that the bristles of the roller brush are easily worn, the cleaning effect gradually deteriorates in the later stage, the self-cleaning process is cumbersome to control, and the cost is high.

[0005] In a first aspect, the present invention provides a cleaning device, comprising:

[0006] Base;

[0007] A roller brush assembly comprises a roller brush and a roller brush cover, wherein the roller brush cover is movably arranged on the base;

[0008] A dirt scraping assembly is movably arranged on the base, and the dirt scraping assembly can move between a dirt scraping position with an interference fit with the roller brush and an avoidance position with a clearance fit with the roller brush, and the dirt scraping assembly and the roller brush cover are linked and matched;

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

[0010] When the cleaning device is in working mode, the scraping assembly moves to the scraping position and can drive the roller brush cover away from the roller brush and form a set gap between the roller brush and the roller brush;

[0011] When the cleaning device is in the self-cleaning mode, the cleaning device is located in the base station, the scraping component moves to the avoidance position, and can drive the roller brush cover to approach the roller brush and contact the bristles on the roller brush to achieve self-cleaning of the roller brush cover.

[0012] Beneficial effect: When the cleaning equipment is performing normal cleaning work, the scraping component moves to the scraping position where it has an interference fit with the bristles of the roller brush, which can effectively clean the dirt on the bristles. After the cleaning work is completed, the whole machine is placed on the base station to start the self-cleaning mode, and the scraping component moves to the avoidance position where it has a gap with the bristles of the roller brush, so that the scraping component is separated from the roller brush, avoiding the problem of bristle wear caused by the interference fit between the two in the self-cleaning mode. At the same time, due to the linkage between the scraping component and the roller brush cover, the scraping component can drive the roller brush cover to rotate in the direction close to the roller brush when moving to the avoidance position, so that the roller brush cover and the roller brush remain in close contact. At this time, the roller brush can be controlled to rotate forward and reversely to achieve self-cleaning of the roller brush cover. The present application links the scraping assembly with the roller brush cover, so that when the cleaning device performs self-cleaning, the scraping assembly can not only move to an avoidance position to avoid the roller brush to reduce the friction between it and the roller brush, thereby increasing the service life of the roller brush and reducing the replacement frequency of the roller brush, but also drive the roller brush cover to move to a position in contact with the roller brush to clean the dirt on the roller brush cover. Only one driving device is required to control the movement of the two components, the scraping assembly and the roller brush cover, thereby saving control costs, simplifying control steps, and effectively solving the problem that the scraping assembly and the roller brush cover of the self-cleaning device in the related art need to be driven by a separate driving mechanism, and the control process is relatively cumbersome and costly.

[0013] In an optional embodiment, the roller brush cover is rotatably arranged on the base, and a linkage component is arranged on the dirt scraping assembly;

[0014] The linkage component is limitedly matched with the roller brush cover to convert the movement of the scraping assembly into power for the roller brush cover to rotate in a direction close to or away from the roller brush.

[0015] Beneficial effect: through the linkage component set on the scraping assembly and limitedly matched with the roller brush cover, when the scraping assembly moves to the avoidance position, the roller brush cover can be driven by the linkage component to rotate to the self-cleaning position in contact with the roller brush, thereby facilitating the roller brush to clean the roller brush cover; when the scraping assembly moves to the scraping position, the roller brush cover can be driven by the linkage component and / or the action of the reset part to rotate to the initial position matched with the roller brush gap, thereby effectively ensuring that when the cleaning equipment is performing normal cleaning work, there is a set gap between the roller brush cover and the roller brush, and will not interfere with the movement of the roller brush.

[0016] In an optional embodiment, the roller brush cover includes a roller brush cover body and a connecting portion, one end of the connecting portion is fixed to the roller brush cover body, the other end is limitedly matched with the linkage component, and the middle portion is rotatably connected to the base;

[0017] When the dirt scraping assembly moves to the dirt scraping position, the roller brush cover body can rotate in a direction away from the roller brush under the drive of the linkage component;

[0018] When the dirt scraping assembly moves to the avoidance position, the linkage component can push the roller brush cover body to rotate in a direction close to the roller brush through the connecting portion.

[0019] Beneficial effect: The roller brush cover adopts the design of the above-mentioned connecting part, and the connecting part can not only realize the rotation connection between the roller brush cover and the base, but also can cooperate with the linkage component to realize the linkage between the roller brush cover and the scraping assembly, so that one thing can be used for multiple purposes and the structure is further simplified. In addition, the connecting part adopts the method of rotational connection with the base in the middle part, and the two ends cooperate with the roller brush cover body and the scraping assembly respectively, so that the entire roller brush cover forms a lever-like structure, which can change the direction of the force, so that the scraping assembly can drive the roller brush cover body to move downward when pushing the connecting part upward, and close to the roller brush, which not only makes the position of the scraping assembly unrestricted, facilitating the installation layout of the scraping assembly, but also enables the scraping assembly to drive the roller brush cover to move more easily and labor-savingly.

[0020] In an optional embodiment, the linkage component is a push-up protrusion provided on the scraping assembly, and the push-up protrusion is abutted and matched with the roller brush cover.

[0021] Beneficial effects: The linkage component adopts the form of a push-up protrusion, which has a simple structure and is easy to process and form, and the linkage between the scraping assembly and the roller brush cover is achieved by abutting and cooperating between the push-up protrusion and the roller brush cover. Compared with the hinged and hooked methods, the linkage method is simpler and more reliable, and is also convenient for disassembly and assembly as well as later maintenance.

[0022] In an optional embodiment, two sets of connecting parts are provided at both ends of the roller brush cover body along the axial direction of the roller brush;

[0023] Two groups of linkage components are correspondingly arranged, and the two groups of linkage components are matched with the two groups of connection parts in a one-to-one correspondence.

[0024] Beneficial effect: By setting two groups of connecting parts at both ends of the roller brush cover body and two groups of linkage components correspondingly set, the two groups of linkage components are abutted and matched with the two groups of connecting parts one by one, so that the roller brush cover body can be pushed from both sides, making the movement of the roller brush cover body more balanced and stable.

[0025] In an optional embodiment, the roller brush assembly further includes:

[0027] The first restoring member is arranged on the first rotating shaft and can apply a restoring force to the roller brush cover body to rotate in a direction away from the roller brush.

[0028] Beneficial effect: By setting the first reset member on the first rotating shaft, the roller brush cover can have a tendency to rotate in the direction away from the roller brush. When the scraping assembly moves to the scraping position and no longer presses down the roller brush cover, the first reset member can give an upward reset force to the roller brush cover body, so that the roller brush cover can automatically reset to the initial position that matches the roller brush gap, thereby effectively ensuring the normal progress of the cleaning work.

[0029] In an optional embodiment, the scraping assembly is rotatably mounted on the base, and the cleaning device further comprises:

[0030] The driving device is connected to the dirt scraping assembly and is used for driving the dirt scraping assembly to rotate between a dirt scraping position and an avoidance position.

[0031] Beneficial effect: The scraping assembly can be rotatably mounted on the base. When the cleaning equipment is performing normal cleaning and self-cleaning operations, the driving device can be used to control the scraping assembly to rotate between the scraping position and the avoidance position. This ensures that the scraping performance of the scraping assembly is ensured while also ensuring that the scraping assembly is separated from the roller brush during the self-cleaning process, thereby reducing the friction between the scraping assembly and the roller brush and increasing the service life of the roller brush.

[0032] In an optional embodiment, the driving device includes:

[0033] A power mechanism having an output shaft;

[0034] The transmission mechanism comprises a driving gear and a driven gear, wherein the driving gear is fixed on the output shaft, and the driven gear is meshed and driven between the driving gear and the scraping assembly;

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

[0036] Beneficial effect: The driving device adopts a driving gear and a driven gear as a transmission mechanism, and the transmission is accurate and reliable, so that the scraping component can move accurately between the scraping position and the avoidance position.

[0037] In an optional embodiment, the power mechanism includes:

[0038] A drive motor having an output shaft;

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

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

[0041] In an optional embodiment, the cleaning device further comprises:

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

[0043] Beneficial effect: Through the set position detection mechanism, the position of the scraping component can be accurately controlled to ensure the accuracy of the scraping stroke, and avoid excessive or inadequate movement of the scraping component when moving between the scraping position and the avoidance position, thereby affecting the scraping and cleaning effect of the scraping component on the roller brush, or the scraping component and the roller brush cannot be effectively separated in the self-cleaning mode, and the bristles still have wear problems.

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

[0045] When the scraping assembly moves to the scraping position, the trigger member can trigger the first position switch;

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

[0047] Beneficial effect: when the cleaning device receives a cleaning instruction, the driving device drives the scraping assembly to rotate to the scraping position, and the trigger can trigger the first position switch. When the cleaning device receives the trigger signal of the first position switch, the driving device is controlled to stop driving the scraping assembly to rotate, so that the scraping assembly remains in the scraping position. At this time, the roller brush is controlled to rotate at a high speed, and the scraping assembly can clean the dirt on the roller brush, hang the dirt, and suck it away through the dirt suction mechanism, thereby ensuring the scraping performance of the scraping assembly; when the whole machine is placed in the base station and receives a self-cleaning instruction, the driving device drives the scraping assembly to rotate When it reaches the avoidance position, the trigger member can trigger the second position switch. When the cleaning device receives the trigger signal of the second position switch, it controls the driving device to stop driving the scraping assembly to rotate, so that the scraping assembly remains in the avoidance position. At this time, the scraping assembly is disengaged from the roller brush to prevent friction. At the same time, the linkage component on the scraping assembly rotates upward, and the linked roller brush cover is linked to make the roller brush cover rotate downward to the self-cleaning position in contact with the bristles on the roller brush. At this time, the roller brush cover and the bristles have a slight interference fit, and then the roller brush is controlled to reverse forward and backward, and the bristles on the roller brush can realize self-cleaning of the dirt on the roller brush cover.

[0048] In an optional embodiment, the dirt scraping assembly includes:

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

[0050] The scraper is installed on the support and is provided with a plurality of scraping teeth for scraping dirt on the bristles of the roller brush.

[0051] Beneficial effect: By means of the linkage component arranged on the support, the linkage between the scraping assembly and the roller brush cover can be achieved, so that during the self-cleaning process, the roller brush cover can rotate downward under the linkage of the linkage component, thereby facilitating the bristles on the roller brush to clean the dirt on the scraping assembly, thereby improving the cleaning effect without the need to separately set up a driving mechanism to drive the roller brush cover to move, thereby simplifying the structure and control steps and saving control costs.

[0084] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0085] In order to clean the roller brush, the existing cleaning equipment usually makes the scraper into a comb-tooth shape and fixes it on one side of the roller brush, or uses a floating comb-tooth scraper, which is pushed by the spring at the back to scrape the dirt off the roller brush when the roller brush rotates at high speed to clean the ground. In order to achieve the expected scraping and cleaning effect, the comb-tooth scraper and the roller brush need to have an interference fit to scrape and suck away the dirt. When driven by the roller brush motor, the comb-tooth scraper and the roller brush have an interference fit for a long time, which easily causes the bristles on the roller brush to wear. As a result, after the cleaning equipment is used for a long time, the bristles on the roller brush gradually shorten, the gap between the comb-tooth scraper and the roller brush increases, and the scraping and cleaning effect gradually decreases.

[0086] When the cleaning equipment is working normally, it mainly uses the rotating roller brush to remove the sewage and garbage on the ground. The rotating roller brush may roll up the garbage and throw it away. At the same time, the water spraying mechanism of the floor brush sprays water on the roller brush, which will cause water splashing. Therefore, a roller brush cover is usually installed on the roller brush to avoid the problem of garbage being thrown out and water splashing on the roller brush. Because the main function of the roller brush cover is to block the thrown garbage and splashing water, garbage and sewage will be attached to the roller brush cover. Therefore, the roller brush cover needs to be cleaned daily. If it is not cleaned for a long time, it will cause bacteria to grow on the roller brush cover and produce odor.

[0087] During the self-cleaning process of the cleaning device 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, and then control the roller brush to rotate forward and reverse to scrape off the dirt on the roller brush cover to achieve self-cleaning of the cleaning device. The entire control process is relatively cumbersome and costly. However, the self-cleaning process does not require a comb scraper to clean the dirt on the roller brush, and a fixed scraper or a floating scraper cannot effectively avoid the roller brush, resulting in long-term friction between the scraper and the roller brush, which shortens the length of the bristles on the roller brush due to long-term friction, shortens the service life, and increases the gap between the scraper and the roller brush, which reduces the scraping and cleaning effect, and will also affect the cleaning effect over time.

[0088] At present, in the industry, in order to solve the problem that the roller brush of cleaning equipment is easy to wear and the cleaning effect gradually deteriorates in the later stage, most of them adopt the method of replacing the roller brush, which has a high frequency of replacement and high cost. In addition, the existing self-cleaning equipment needs to set up a separate driving mechanism to drive the roller brush cover to move, and the control process is relatively cumbersome and costly, which is not conducive to the use and promotion of the product.

[0089] Combine the following Figures 1 to 20 , describing an embodiment of the present invention.

[0090] According to an embodiment of the present invention, on the one hand, the present invention provides a cleaning device 100, including a base 10, a roller brush assembly 20, and a scraping assembly 30, wherein the roller brush assembly 20 includes a roller brush 21 and a roller brush cover 22, and the roller brush cover 22 is movably arranged on the base 10; the scraping assembly 30 is movably arranged on the base 10, and the scraping assembly 30 can move between a scraping position with an interference fit with the roller brush 21 and an avoidance position with a clearance fit with the roller brush 21, and the scraping assembly 30 and the roller brush cover 22 are linked and cooperated; the cleaning device The device 100 has a working mode and a self-cleaning mode: when the cleaning device 100 is in the working mode, the scraping assembly 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 in the base station 200, the scraping assembly 30 moves to the avoidance position, and can drive the roller brush cover 22 to approach 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 has an interference fit with the bristles of the roller brush 21, so as to effectively clean the dirt on the bristles. After the cleaning work is completed, the whole machine is placed on the base station 200 to start the self-cleaning mode, and the scraping component 30 moves to the avoidance position where it has a gap with the bristles of the roller brush 21, so that the scraping component 30 is separated from the roller brush 21, thereby avoiding the problem of bristle wear caused by the interference fit between the two in the self-cleaning mode. At the same time, due to the linkage between the scraping component 30 and the roller brush cover 22, the scraping component 30 can drive the roller brush cover 22 to rotate in the direction close to the roller brush 21 when moving to the avoidance position, so that the roller brush cover 22 and the roller brush 21 remain in close contact. At this time, the roller brush 21 can be controlled to rotate forward and reversely to achieve self-cleaning of the roller brush cover 22. The present application links the scraper assembly 30 with the roller brush cover 22. When the cleaning device 100 performs self-cleaning, the scraper assembly 30 can not only move to an avoidance position to avoid the roller brush 21 to reduce the friction between it and the roller brush 21, thereby increasing the service life of the roller brush 21 and reducing the replacement frequency of the roller brush 21, but also drive the roller brush cover 22 to move to a position in contact with the roller brush 21 to clean the dirt on the roller brush cover 22. Only one driving device 40 is required to control the movement of the two components, the scraper assembly 30 and the roller brush cover 22, thereby saving control costs, simplifying control steps, and effectively solving the problem that the scraper assembly 30 and the roller brush cover 22 of the self-cleaning device 100 in the related art need to be driven by a separate driving mechanism, and the control process is relatively cumbersome and costly.

[0092] In this embodiment, the roller brush cover 22 is located above the roller brush 21, and the roller brush cover 22 and the dirt scraping assembly 30 can be matched through a linkage mechanism, or can be linked through direct contact. When the cleaning device 100 is performing normal cleaning work, the roller brush 21 rotates at a high speed, and the dirt scraping assembly 30 is in a dirt scraping position with an interference fit with the bristles of the roller brush 21, and can scrape off the dirt on the bristles in time. 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 is not scraped off by the dirt scraping assembly 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 is no longer performing the cleaning work, the scraping assembly 30 does not need to clean the roller brush 21, and the scraping assembly 30 moves to an avoidance position that cooperates with the bristle gap of the roller brush 21. At this time, the roller brush cover 22 rotates downward under the linkage of the scraping assembly 30, keeps close contact with the roller brush 21, and then realizes self-cleaning of the dirt attached to the roller brush cover 22 by controlling the forward and reverse rotation of the roller brush 21.

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

[0094] In the above embodiment, by means of a linkage component provided on the scraping assembly and limited in position with the roller brush cover, when the scraping assembly moves to the avoidance position, the roller brush cover can be driven by the linkage component to rotate to the self-cleaning position in contact with the roller brush, thereby facilitating the roller brush to clean the roller brush cover; when the scraping assembly moves to the scraping position, the roller brush cover can be driven by the linkage component and / or by the reset member to rotate to the initial position that cooperates with the roller brush gap, thereby effectively ensuring that when the cleaning device 100 is performing normal cleaning work, there is a set gap between the roller brush cover and the roller brush, and will not interfere with the movement of the roller brush.

[0095] Specifically, when the scraping assembly moves to the avoidance position, the linkage component can convert the movement of the scraping assembly into a downward pressure applied to the roller brush cover, so that the roller brush cover and the roller brush are in contact and matched. The limiting matching methods of the linkage component and the roller brush cover include but are not limited to hinge, hook, abutment, etc. Exemplarily, the linkage component can adopt a structure in the form of an articulated seat, a pull ring, a hook, a protrusion, etc.

[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, and 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 assembly 30 moves to the scraping position, the roller brush cover body 221 can be driven by the linkage component 301 to rotate in the direction away from the roller brush 21; when the scraping assembly 30 moves to the avoidance position, the linkage component 301 can push the roller brush cover body 221 to rotate in the direction close to the roller brush 21 through the connecting portion 222.

[0097] In the above embodiment, the roller brush cover 22 adopts the design of the above-mentioned connecting portion 222, and the connecting portion 222 can not only realize the rotation connection between the roller brush cover 22 and the base 10, but also can cooperate with the linkage component 301 to realize the linkage between the roller brush cover 22 and the scraping assembly 30, so that one thing can be used for multiple purposes, and the structure is further simplified. In addition, the connecting portion 222 adopts a method of rotational connection with the base in the middle part, and the two ends cooperate with the roller brush cover body and the scraping assembly respectively, so that the entire roller brush cover 22 forms a lever-like structure, which can change the direction of the force, so that the scraping assembly can drive the roller brush cover body to move downward when pushing the connecting portion upward, and close to the roller brush, which not only makes the position of the scraping assembly unrestricted, but also facilitates the installation layout of the scraping assembly, and also enables the scraping assembly to drive the roller brush cover to move more easily and labor-savingly.

[0098] Specifically, the roller brush cover body 221 is an arc-shaped plate-like structure, and a first axial hole is opened in the middle of the connecting part 222. The first axial hole and the base 10 are connected by the 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 provided with a first rotating shaft 23.

[0099] When the cleaning device 100 is performing cleaning work normally, the scraping assembly 30 moves to the scraping position. At this time, the roller brush cover body 221 can be driven by the linkage component 301 to rotate in the direction away from the roller brush 21 to avoid interfering with the high-speed rotating roller brush 21; when the cleaning device 100 is performing self-cleaning, the scraping assembly 30 moves to the avoidance position. At this time, the linkage component 301 can push the roller brush cover body 221 to rotate in the direction close to the roller brush 21 through the connecting part 222, so that the roller brush cover body 221 is in contact and cooperate with the bristles of the roller brush 21. 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, in combination Figures 18 to 20 As shown, the linkage component 301 is a push-up protrusion arranged on the scraping component 30, and the push-up protrusion is abutted and matched with the roller brush cover.

[0101] In the above embodiment, the linkage component 301 adopts the form of a push-up protrusion, which has a simple structure and is easy to process and form, and the linkage between the scraping assembly and the roller brush cover is achieved by abutting and cooperating between the push-up protrusion and the roller brush cover. Compared with the hinged and hooked methods, the linkage method is simpler and more reliable, and is also convenient for disassembly and assembly as well as later maintenance.

[0102] Furthermore, the roller brush cover body 221 has an inner wall facing the roller brush 21 and an outer wall facing away from the roller brush 21, and the connecting portion 222 is a connecting rib fixedly arranged on the outer wall, and the connecting rib abuts against the push-up protrusion. The connecting portion 222 adopts the form of a connecting rib fixedly arranged on the outer wall of the roller brush cover body 221, and has a simple structure and is easy to process and form.

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

[0104] In some embodiments, two groups of connection parts 222 are provided at both ends of the roller brush cover body 221 along the axial direction of the roller brush 21 ; two groups of linkage components 301 are correspondingly provided, and the two groups of linkage components 301 are matched with the two groups of connection parts 222 in a one-to-one correspondence.

[0105] In the above embodiment, by providing two groups of connecting parts 222 at both ends of the roller brush cover main body 221 and two groups of linkage components 301 correspondingly provided, the two groups of linkage components 301 are abutted and matched with the two groups of connecting parts 222 in a one-to-one correspondence, thereby enabling the roller brush cover main body 221 to be pushed from both sides, making the movement of the roller brush cover main body 221 more balanced and stable.

[0106] In some embodiments, the roller brush assembly 20 also includes a first rotating shaft 23 and a first reset member 24, and the connecting portion 222 is rotatably connected to the base 10 through the first rotating shaft 23; the first reset member 24 is arranged on the first rotating shaft 23, and can apply a reset force to the roller brush cover body 221 to rotate in a direction away from the roller brush 21.

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

[0108] Preferably, the first reset member 24 is a torsion spring, which is sleeved on the first rotating shaft 23, and the two ends of the torsion spring are respectively abutted against the roller brush cover body 221 and the base 10. When the pushing protrusion does not lift the connecting part to press down the roller brush cover body, the torsion spring can give the roller brush cover body an upward reset force to restore the gap between the roller brush cover body and the roller brush for normal cleaning work.

[0109] Of course, in other alternative implementations, the first restoring member 24 may also be a tension spring, for example, which is not limited in this embodiment.

[0110] In this embodiment, along the circumferential direction of the roller brush cover main body 221, the connection position between the connecting rib and the roller brush cover main body 221 is located on one side of the arc-shaped roller brush cover main body 221. When the scraping assembly 30 moves to the avoidance position, the linkage part 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 main body 221 to rotate downward, pressing the roller brush cover main body 221 downward, so that the roller brush cover main body 221 contacts and cooperates with the roller brush 21; when the scraping assembly 30 moves to the scraping position, the linkage part 301 moves upward, and the second arm falls accordingly under the action of the first reset member 24. Under the action of the lever, the first arm drives the roller brush cover main body 221 to rotate upward, lifting the roller brush cover main body 221, so that the roller brush cover main body 221 is out of contact with the roller brush 21 and a set gap is formed.

[0111] In some embodiments, the roller brush assembly 20 also includes a sealing strip 25, which is disposed on the inner edge of the roller brush cover body 221. The setting of the sealing strip 25 enables a seal between the roller brush cover body 221 and the middle cover plate 13 of the base 10, thereby 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 locations in the base 10, thereby 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 driving device 40, which is connected to the scraping assembly 30 and is used to drive the scraping assembly 30 to rotate between the scraping position and the avoidance position.

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

[0114] Of course, in other alternative embodiments, the scraping assembly 30 can also be slidably set on the base 10. For example, the scraping assembly 30 is translatedly set in the base 10, and the scraping assembly 30 can be driven by a driving mechanism to move between the scraping position and the avoidance position. The linkage component 301 and the connecting part 222 of the roller brush cover 22 can be linked by a bevel fit.

[0115] In some embodiments, the driving 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 driving gear 421 and a driven gear 422, the driving gear 421 is fixed on the output shaft, and the driven gear 422 is meshed and transmitted between the driving gear 421 and the scraping assembly 30; the power mechanism 41 drives the scraping assembly 30 to rotate between the scraping position and the avoidance position through the driving gear 421 and the driven gear 422.

[0116] In the above embodiment, the driving device 40 uses a driving gear 421 and a driven gear 422 as the transmission mechanism 42, and the transmission is accurate and reliable, so that the scraping assembly 30 can move accurately 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 installed on the motor bracket 412, and the transmission mechanism 42 also includes a gear cover 43, the gear cover 43 is used to cooperate with the motor bracket 412 to limit the driving gear 421 and the driven gear 422 between it 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 the two, thereby improving the stability of the driving gear and the driven gear structure.

[0119] Specifically, the motor bracket 412 includes a motor accommodating portion and a gear mounting portion, the gear mounting portion includes a mounting plate fixedly arranged on one side of the motor accommodating portion, a connecting shaft for mounting the driven gear 422 is fixedly arranged on the mounting plate, the driven gear 422 is rotatably sleeved and mounted on the connecting shaft, and an opening is also provided on the mounting plate for the output shaft of the driving motor 411 to extend out, the output shaft of the driving motor 411 extends out of the opening and is connected and fixed to the driving gear 421. A bolt column is provided on the motor bracket 412, and the gear cover 43 is fixed to the bolt column of the motor bracket 412 by screws 46.

[0120] Furthermore, the driving device 40 also includes a motor bracket cover 413. A mounting groove for accommodating the driving motor 411 is set in the motor bracket 412. The mounting groove is set with a top opening. The motor bracket cover 413 is detachably installed and fixed at the notch of the mounting groove to seal the driving motor 411 in the mounting groove.

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

[0122] In the above embodiment, by setting up a position detection mechanism, the position of the scraping component can be accurately controlled to ensure the accuracy of the scraping stroke, and avoid excessive or inadequate movement of the scraping component when moving between the scraping position and the avoidance position, thereby affecting the scraping and cleaning effect of the scraping component on the roller brush, or the scraping component and the roller brush cannot be effectively separated in the self-cleaning mode, and the bristles still have wear problems.

[0123] Optionally, the position detection mechanism may be in the form of a distance sensor, a photoelectric sensor, an infrared sensor, a position switch, etc. The position detection mechanism may be arranged on the driving device, the scraping component or the base.

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

[0125] In the above embodiment, when the cleaning device 100 receives a cleaning instruction, the driving device 40 drives the scraping assembly 30 to rotate to the scraping position, and the trigger member 4211 can trigger the first position switch 44. When the cleaning device 100 receives the trigger signal of the first position switch 44, the driving device 40 is controlled to stop driving the scraping assembly 30 to rotate, so that the scraping assembly 30 remains in the scraping position. At this time, the roller brush 21 is controlled to rotate at a high speed, and the scraping assembly 30 can clean the dirt on the roller brush 21, hang the dirt off, and suck it away through the dirt suction mechanism, thereby ensuring the scraping performance of the scraping assembly 30; when the whole machine is placed in the base station and receives a self-cleaning instruction, the driving device 40 drives the scraping assembly 30 to rotate to When in the avoidance position, the trigger member 4211 can trigger the second position switch 45. When the cleaning device 100 receives the trigger signal of the second position switch 45, it controls the driving device 40 to stop driving the scraping assembly 30 to rotate, so that the scraping assembly 30 remains 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 to link the roller brush cover 22, so that the roller brush cover 22 rotates downward to the self-cleaning position in contact with the bristles on the roller brush 21. At this time, the roller brush cover 22 has a slight interference with the bristles, and then the roller brush 21 is controlled to rotate forward and reverse, and the bristles on the roller brush 21 can realize self-cleaning of the dirt on the roller brush cover 22.

[0126] Optionally, the trigger member is arranged on the scraping assembly or the driving device, and the first position switch and the second position switch are arranged on the side wall of the base or the driving device.

[0127] In some specific embodiments, the first position switch 44 and the second position switch 45 are arranged on the gear cover 43, and the trigger 4211 is arranged on the driving gear 421. By arranging the first position switch 44 and the second position switch 45 on the gear cover, compared with arranging them on the motor bracket, the installation space is larger, and the assembly and maintenance of the first position switch 44 and the second position switch 45 are more convenient. By arranging the trigger on the driving gear, compared with arranging it on the driven gear, the speed of the driving motor can be directly fed back without conversion, the response is more timely, and the control is more accurate and efficient.

[0128] Of course, in other alternative embodiments, the first position switch 44 and the second position switch 45 may also be set on the shell of the base or on the motor bracket, and the trigger member 4211 may also be set on the driven gear or the scraping assembly. This embodiment does not limit the specific positions of the first position switch 44, the second position switch 45 and the trigger member 4211.

[0129] Furthermore, the gear cover 43 is provided with mounting columns for mounting the first position switch 44 and the second position switch 45. Two groups of mounting columns are provided on the gear cover 43. The two groups of mounting columns are corresponding to the installation of the two position switches. Each group of mounting columns includes two mounting columns arranged at intervals. Each position switch is provided with two mounting through holes. The position switch is mounted on the mounting column through the two mounting through holes thereon. By installing the first position switch 44 and the second position switch 45 in the above manner, not only the stability of the structure of the first position switch 44 and the second position switch 45 can be ensured, but also disassembly and assembly are convenient. When disassembly is required, the position switch can be directly removed from the mounting column. When installation is required, it can be directly mounted on the mounting column.

[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 active gear 421 rotates, it drives the trigger member 4211 to move in a set arc track, and the first position switch 44 and the second position switch 45 are arranged on the gear cover 43 at intervals along the arc track. The first position switch 44 and the second position switch 45 are respectively provided with trigger parts on the two opposite inner sides. When the trigger member 4211 moves driven by the active gear 421, the trigger part can be triggered to trigger 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 driving device 40 is as follows: the driving motor 411 is placed in the installation groove of the motor bracket 412, and the motor bracket cover 413 is snapped into the notch of the motor bracket 412, and the driving gear 421 is installed in the output shaft of the driving motor 411, and the support ring 414 is inserted into the output shaft to press the driving gear 421, and then the driven gear 422 is installed into the motor bracket 412, and then the gear cover 43 and the motor bracket 412 are matched to press the driven gear 422, and then the gear cover 43 is fixed to the motor bracket 412 with screws 46, and then the first position switch 44 and the second position switch 45 are assembled on the gear cover 43, and the entire driving device 40 is assembled.

[0132] Optionally, the base 10 includes an upper shell 11, a lower shell 12 and a middle cover plate 13 arranged between the upper shell 11 and the lower shell 12, and an installation space for installing the drive device 40 is enclosed between the middle cover plate 13 and the lower shell 12, and the drive device 40 is fixed on the lower shell 12.

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

[0134] In the above embodiment, the first position switch 44 and the second position switch 45 are arranged 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 has a simple structure and is easy to process. An opening is opened on the gear cover 43 for the trigger rod to pass through and to avoid the movement of the trigger rod, so that the trigger rod can be triggered and coordinated with the first position switch 44 and the second position switch 45.

[0135] Specifically, the trigger rod is fixedly arranged on the outer peripheral side of the gear cover 43. The opening on the gear cover 43 is an arc-shaped opening, and the trigger rod can move in an arc-shaped trajectory in the opening. By installing the first position switch 44 and the second position switch 45 on the gear cover 43, the overall structure can be made more compact and the space utilization rate can be improved.

[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. A linkage component 301 for cooperating with the roller brush cover 22 is provided on the support 31. An engaging portion 310 for engaging and transmitting with the driven gear 422 is also provided on the support 31. The scraper 32 is installed on the support 31. A plurality of scraping teeth for scraping dirt off the bristles of the roller brush 21 are provided on the scraper 32.

[0137] In the above embodiment, by means of the meshing portion 310 provided on the support 31, the meshing transmission between the meshing portion 310 and the driven gear 422 can be utilized to drive the entire scraping assembly 30 to rotate between the scraping position and the avoidance position. By means of the linkage component 301 provided on the support 31, the linkage between the scraping assembly 30 and the roller brush cover 22 can be achieved, so that during the self-cleaning process, the roller brush cover 22 can rotate downward under the linkage of the linkage component 301, thereby facilitating the bristles on the roller brush 21 to clean the dirt on the scraping assembly 30. While improving the cleaning effect, there is no need to separately set a driving mechanism to drive the roller brush cover 22 to move, thereby simplifying the structure and control steps, and saving control costs.

[0138] Specifically, two second rotating shafts are fixedly arranged on both sides of the support 31, and a rotating sleeve 313 is rotatably sleeved on the two second rotating shafts, and the rotating sleeve 313 is connected to the base 10, so as to realize the rotation connection between the support 31 and the base 10. The meshing portion 310 is a sector gear fixedly arranged on the support 31, and preferably, the meshing portion 310 and the support 31 are integrally formed. The scraper 32 is screwed to the support 31 for easy disassembly and assembly, and a plurality of scraping teeth are arranged on one side edge of the scraper 32 close to the roller brush 21, which can scrape off the dirt on the bristles.

[0139] Furthermore, the dirt scraping assembly 30 also includes a second reset member 314, a water baffle 33, and a pressure plate 34. The second reset member 314 is installed on the support 31 to apply a force to the entire dirt scraping assembly 30 to rotate toward the dirt scraping position. The second reset member 314 can apply a force to the scraper to move in the direction close to the roller brush, thereby avoiding the high flexibility of the dirt scraping assembly 30, which will rotate at will and become unstable. Two mounting shafts are provided at both ends of the support 31, and the second reset member 314 is correspondingly installed on the two mounting shafts. Preferably, the second reset member 314 is a torsion spring sleeved on the mounting shaft, and the two ends of the torsion spring are respectively in contact with the support 31 and the base 10. Of course, in other alternative embodiments, the second reset member 314 can also adopt a structural form such as a compression spring, which is not limited in this embodiment.

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

[0141] In some embodiments, 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 above-mentioned base 10, a roller brush assembly 20, a scraping assembly 30, a driving device 40, etc.

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

[0143] The following describes the assembly steps, working process, control method, etc. of the cleaning device 100 of this embodiment in conjunction with the accompanying drawings.

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

[0145] Fix the driving device 40 to the lower shell 12 of the base 10 with screws; mesh the meshing portion 310 of the scraping assembly 30 with the driven gear 422 of the driving device 40 and assemble them at the front end of the lower shell 12, then press the scraping assembly 30 with the middle cover 13, then install the roller brush 21 into the front end of the scraping assembly 30, and then install the roller brush cover 22 over the roller brush 21 to cover the roller brush 21 and the scraper 32, and the floor brush of the cleaning device 100 is assembled.

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

[0147] When the cleaning device 100 cleans the floor normally, the driving motor 411 drives the scraping assembly 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 to start the self-cleaning mode. At this time, the driving motor 411 drives the active gear 421 and the driven gear 422 to move, driving the scraping assembly 30 to rotate and move backward to the avoidance position, so that the scraper 32 is separated from the roller brush 21 to avoid interference. At the same time, the linkage component 301 on the scraping assembly 30 moves, driving the roller brush cover 22 to rotate downward and keep close to the roller brush 21. At this time, the roller brush 21 reverses for self-cleaning, and the scraping assembly 30 moves to the avoidance position, which can not only avoid the roller brush 21, avoid the friction between the scraper 32 and the roller brush 21, and increase the service life of the roller brush 21, but also make the roller brush cover 22 fit with the roller brush 21 to clean the dirt on the roller brush cover 22.

[0148] Furthermore, during the process of cleaning the floor with the cleaning device 100, the driving motor 411 drives the driving gear 421, and the driving gear 421 can drive the driven gear 422. The driven gear 422 drives the scraper 32 to rotate forward and contact the roller brush 21 through the meshing portion 310 on the scraping assembly 30 (due to limited space, only a limited meshing portion of the gear is left, so the meshing portion 310 is made into a fan-shaped gear). When the trigger member 4211 on the driving gear 421 touches the first position switch 44, the driving motor 411 stops moving, and the scraper 32 rotates to the frontmost 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, scrape the dirt off, and then suck it away through the dirt suction chamber.

[0149] When the floor scrubber finishes cleaning the floor, it is placed in the base station 200. After receiving the self-cleaning command, the drive motor 411 drives the scraper 32 to rotate backward through the transmission mechanism 42. When the trigger member 4211 on the driving gear 421 touches the second position switch 45, the backward rotation movement of the drive motor 411 stops. At this time, the scraper rotates to the rear end, the scraper 32 is disengaged from the roller brush 21, and the scraper 32 and the bristles maintain a gap, so that self-cleaning can be performed. At the same time, the linkage component 301 on the scraper 32 rotates upward, and the roller brush cover 22 is linked to drive the roller brush cover 22 to rotate downward, so that the roller brush cover 22 and the bristles on the roller brush 21 are slightly interfered. After the roller brush starts to rotate, the 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 life of the roller brush 21. Under the premise of ensuring the scraping performance of the scraper 32, in order to increase the service life of the roller brush 21, during the self-cleaning process, the scraper 32 is controlled to separate from the roller brush 21 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 be realized, and the service life of the roller brush 21 can be increased. At the same time, the dirt on the roller brush cover 22 is cleaned synchronously, and the dirt on the roller brush cover 22 is self-cleaned, thereby improving the service life of the roller brush 21 and the cleaning effect of the whole machine.

[0151] 3. The control method of the cleaning device 100 is as follows:

[0152] Step A, working mode, including smart mode or powerful mode, the function is for the user to choose whether to clean according to his own judgment;

[0153] Step B, self-cleaning mode; the function is that the user can choose whether to self-clean according to his own judgment;

[0154] More detailed, step A, smart mode or powerful mode:

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

[0156] During the forward rotation of step A-②, the machine determines whether the first position switch 44 is closed. If it is closed, the machine proceeds to step A-③. If it is not closed, the driving motor 411 continues to operate until it is closed within the specified time t, and then proceeds to step A-③. If it is not closed, the machine directly jumps to step A-⑦.

[0157] Step A-③ After the first position switch is closed, the drive motor 411 no longer operates;

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

[0159] Step A-⑤Continue to work for a set period of time;

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

[0161] Step A-⑦ The cleaning device 100 is shut down.

[0162] In more detail, step B, self-cleaning mode:

[0163] Step B-① The driving motor 411 rotates forward to drive the entire structure to 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, the driving motor 411 continues to operate until it is closed within the specified time t, and continue to B-③. If it is not closed, jump directly to A-⑦;

[0165] Step B-③ After the second position switch is closed, the drive motor 411 no longer runs;

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

[0167] Step A-⑤Continue to work for a set period of time;

[0168] Step A-⑥ determines whether the user chooses to stop; "yes" continues to A-⑦; "no" returns to the working mode selection.

[0169] Step A-⑦ The cleaning device 100 is shut down.

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

[0171] The cleaning device 100 provided in this embodiment can, according to the cleaning state, during the cleaning process, the scraper 32 can effectively cooperate with the roller brush 21 to scrape dirt. During the self-cleaning process, the scraper 32 is controlled to separate from the roller brush 21 by the drive motor 411, thereby reducing the 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 the self-cleaning process, the drive motor 411 drives the scraper 32 to rotate to the avoidance position, and through the linkage between the scraping component 30 and the roller brush cover 22, the roller brush cover 22 can be driven to rotate downward, at which time the bristles on the roller brush 21 will clean the dirt on the roller brush cover 22, thereby achieving effective cleaning of the roller brush cover 22 and improving the cleaning effect of the entire machine.
