Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and cleaning method. Background Technology

[0002] In related technologies, cleaning equipment that involves water cleaning often only has a scraper on one side of the roller brush. However, during operation, the roller brush often leaves behind a significant amount of water residue due to friction with the floor. Therefore, when the cleaning equipment moves along the side of the roller brush away from the scraper, the scraper can clean up the water residue. But when the cleaning equipment moves along the side of the roller brush closer to the scraper, it cannot clean up the water residue, resulting in a poor user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a cleaning device and cleaning method to address the problem of insufficient removal of residual water stains from the roller brush of cleaning equipment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a cleaning device for floor cleaning, the cleaning device comprising:

[0006] Organism;

[0007] A walking component, which is installed at one end of the body and can drive the entire body to move;

[0008] A first cleaning component includes a roller brush mounted on the end of the body away from the walking component;

[0009] The second cleaning component is installed on the side of the roller brush facing away from the walking component and includes a drive mechanism and a scraper mechanism, wherein the drive mechanism is pulsatorically connected to the scraper mechanism.

[0010] The drive mechanism can drive the scraper mechanism to contact or separate from the ground to cooperate with the walking component and realize multiple operating modes of the cleaning equipment.

[0011] The above design adds water stain cleaning methods and improves the user experience.

[0012] In one embodiment of the first aspect, the cleaning device further includes a control component, the body having a dirt channel and a detection mechanism disposed in the dirt channel, the control component being electrically connected to the detection mechanism, the detection mechanism being able to acquire dirt information of the dirt channel and send it to the control component.

[0013] Through the above design, the detection agency can select the appropriate operating mode based on the dirt information of the dirt channel.

[0014] In one embodiment of the first aspect, when the cleaning equipment is in a first operating mode:

[0015] The control component determines that the dirt information of the dirty channel is not dirty, the cleaning device moves along the end where the second cleaning component is located, and the scraper mechanism is controlled to separate from the ground.

[0016] With the above design, the garbage to be cleaned can be rolled up by the roller brush through the gap between the scraper mechanism and the ground, thus achieving effective cleaning of the garbage.

[0017] In one embodiment of the first aspect, the distance between the scraper mechanism and the ground is d, and satisfies: d≥10mm.

[0018] The above design allows the gap between the scraper mechanism and the ground to allow the waste to pass through, and then be rolled up by the roller brush.

[0019] In one embodiment of the first aspect, the first cleaning component further includes a scraper mounted on the side of the roller brush facing away from the scraper mechanism and abutting against the roller brush.

[0020] With the above design, when the roller brush moves forward, the garbage adhering to the roller brush is scraped off, which facilitates subsequent cleaning and collection.

[0021] In one embodiment of the first aspect, when the cleaning equipment is in a second operating mode:

[0022] The control component determines that the dirt information of the dirty channel is not dirty, the cleaning device moves in the direction away from the second cleaning component, and the scraper mechanism is controlled to contact the ground.

[0023] With the above design, the scraper mechanism located at the front end of the roller brush can effectively clean the water stains left on the ground by the roller brush, improving the user experience.

[0024] In one embodiment of the first aspect, when the cleaning equipment is in a third operating mode:

[0025] The control component determines that the dirt information of the dirty channel is dirty, the cleaning equipment moves in any direction, and the scraper mechanism is controlled to separate from the ground.

[0026] The above design avoids the ground from getting too dirty and soiling the scraper mechanism, reducing later maintenance time and extending the service life of the equipment.

[0027] In one embodiment of the first aspect, the walking assembly includes at least one set of walking wheels and a hub motor, each set of walking wheels including two wheels disposed opposite to each other on both sides of the body, the hub motor being mounted on one of the walking wheels and electrically connected to the control assembly.

[0028] Through the above design, the control component can receive the operating signal of the hub motor, determine the running direction of the whole machine, and make adjustments to the operating mode.

[0029] In one embodiment of the first aspect, the walking assembly includes at least one set of walking wheels and an encoder, each set of walking wheels including two wheels disposed opposite to each other on both sides of the body, the encoder being mounted on one of the walking wheels and electrically connected to the control assembly.

[0030] Through the above design, the control component can receive the operation signal from the encoder, determine the running direction of the whole machine, and make adjustments to the operating mode.

[0031] In one embodiment of the first aspect, the first cleaning component further includes a first scraper fixed to the side of the roller brush near the walking component.

[0032] With the above design, the first scraper located at the rear end of the roller brush cleans up water stains, leaving only a shallow water film on the ground, which can be dried quickly.

[0033] In one embodiment of the first aspect, the body includes a first cover and a second cover, the first cover covering the side of the roller brush facing away from the ground, the second cover being located on the side of the first cover facing away from the roller brush, and the scraper mechanism slidingly extending and retracting between the first cover and the second cover.

[0034] Through the above design, the first cover protects the roller brush, and the second cover protects the second cleaning component.

[0035] In one embodiment of the first aspect, the drive mechanism includes a drive motor, a cam, and a linkage group. The drive motor is fixedly installed in the body and connected to the cam. One end of the linkage group is connected to the cam, and the other end is connected to the scraper mechanism. The scraper mechanism is slidably engaged with the first cover.

[0036] The above design enables the extension and retraction of the scraper mechanism, allowing it to contact or separate from the ground.

[0037] In one embodiment of the first aspect, the scraper mechanism includes a bracket, a second scraper, and at least one guide rib. The second scraper is fixed to the lower end of the bracket in the direction of gravity, and each of the guide ribs is arranged parallel to the direction of gravity and fixed to the side of the bracket opposite to the second scraper.

[0038] The first cover body is provided with at least one sliding groove parallel to the direction of gravity, and each sliding groove is distributed in sliding fit with a corresponding guide rib.

[0039] With the above design, under the constraints of the guide rib and the slide groove, the bracket can only move along the extension direction of the slide groove, thereby driving the second scraper fixed to the bottom of the bracket to extend and retract up and down.

[0040] In one embodiment of the first aspect, the first cover is further provided with a first limiting rib and a second limiting rib that are relatively distributed, and the bracket is defined between the first limiting rib and the second limiting rib.

[0041] The above design limits the range of motion of the bracket, thereby achieving precise positioning of the second scraper.

[0042] Secondly, this application also provides a cleaning method using the cleaning equipment described in any of the above embodiments, the cleaning method comprising:

[0043] When the dirty channel is determined to be clean:

[0044] Control the cleaning equipment to move away from the second cleaning component, and control the scraper mechanism to contact the ground to clean up residual water generated when the roller brush rolls up the debris to be cleaned; or

[0045] The cleaning equipment is controlled to move along the end where the second cleaning component is located, and the scraper mechanism is controlled to separate from the ground; the scraper is controlled to block the garbage on the roller brush and suck the garbage into the sewage tank by the fan; the first scraper is controlled to clean the residual water generated by the friction between the roller brush and the ground.

[0046] The above design effectively achieves the cleaning of ground debris and residual water stains.

[0047] In one embodiment of the second aspect, the cleaning method includes:

[0048] When the dirty channel is determined to be dirty:

[0049] The cleaning device is controlled to move away from the second cleaning component or along the end where the second cleaning component is located, and the scraper mechanism is controlled to separate from the ground.

[0050] The above design avoids the ground from getting too dirty and soiling the scraper mechanism, reducing later maintenance time and extending the service life of the equipment.

[0051] Compared to related technologies, the advantages of this application are as follows: This application provides a cleaning device and cleaning method for cleaning water stains left on the ground by a roller brush. The cleaning device includes a body, a walking component, a first cleaning component, and a second cleaning component. The walking component drives the entire body to move. The first cleaning component includes a roller brush mounted at one end of the body, and the second cleaning component is mounted on the side of the roller brush facing away from the walking component. The second cleaning component includes a drive mechanism and a scraper mechanism, with the drive mechanism controlling the scraper mechanism to retract or extend. Thus, when the roller brush moves towards the scraper mechanism, the scraper mechanism retracts in a controlled manner to separate from the ground, thereby not affecting the roller brush's ability to collect and clean debris. When the roller brush moves away from the scraper mechanism, the scraper mechanism extends in a controlled manner to contact the ground, thereby cleaning the residual water stains from the roller brush. Therefore, this application enables multiple operating modes for the cleaning device, increases water stain cleaning methods, and improves the user experience. Attached Figure Description

[0070] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0071] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0072] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0074] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0075] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0076] See Figure 1 As shown, an embodiment of this application provides a cleaning device 100 that can be used for floor cleaning and effectively reduces residual water stains on the floor. For ease of understanding, the cleaning device 100 provided in this application embodiment can be illustrated by a floor scrubber.

[0077] Continue reading Figure 2 As shown, specifically, the cleaning device 100 includes a body 110, a walking assembly 120, a first cleaning assembly 130, and a second cleaning assembly 140. The walking assembly 120 is mounted at one end of the body 110 and can drive the entire body 110 to move. The second cleaning assembly 140 is mounted at the end of the body 110 away from the walking assembly 120. The first cleaning assembly 130 is mounted between the second cleaning assembly 140 and the walking assembly 120.

[0078] It should be noted that, for ease of understanding, the orientations in the embodiments of this application are explained. In this application, the end of the cleaning device 100 with the walking component 120 is called "rear", the end of the cleaning device 100 facing away from the walking component 120 is called "front", the direction above in the direction of gravity is called "up" and "top", and the direction below in the direction of gravity is called "down" and "bottom".

[0079] In some embodiments, the cleaning device 100 further includes a control component, and the walking component 120 includes at least one set of walking wheels 121 and a hub motor 122. Each set of walking wheels 121 includes two wheels that are disposed opposite to each other on both sides of the body 110. The hub motor 122 is mounted on one of the walking wheels 121 and is electrically connected to the control component.

[0080] In this specific embodiment, only one set of traveling wheels 121 is provided, with two traveling wheels 121 respectively installed on two opposite sides of the rear end of the machine body 110. A hub motor 122 is installed in one of the traveling wheels 121, thereby driving the traveling wheel 121 to rotate. The control component can receive the operation signal of the hub motor 122, determine the running direction of the whole machine, and make adjustments to the running mode.

[0081] Specifically, the hub motor 122 refers to integrating the power unit, transmission unit, and braking unit into the hub, thereby simplifying the mechanical parts of the body 110. Understandably, the control components may include a processing chip and several control buttons, and will determine the received signals and issue control commands through an internal operating program.

[0082] Continue reading Figure 3 As shown, in some other embodiments, the walking assembly 120 includes a set of walking wheels 121 and an encoder 123, the encoder 123 being mounted on one of the walking wheels 121 and electrically connected to the control assembly.

[0083] Specifically, the walking component 120 can be an AC asynchronous motor installed in the body 110, which drives the walking wheel 121 to rotate. The encoder 123 installed on the walking wheel 121 obtains the running signal of the walking wheel 121 and sends it to the control component. The control component judges the received signal through its internal running program and issues control commands.

[0084] Of course, the walking assembly 120 can also use other types of motors, as long as they can meet the operation of the walking wheels 121, which will not be listed here. The number of walking wheels 121 can also be two or more, and they can be installed on other sides of the body 110 other than the rear end. The specific selection can be made according to actual needs, as long as it can meet the normal operation of the cleaning equipment 100.

[0085] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, the first cleaning component 130 includes a roller brush 131 mounted on the front end of the body 110.

[0086] Specifically, during the operation of the cleaning equipment 100, the bottom side of the roller brush 131 contacts the ground, and the traveling wheel 121 drives the whole machine to move, thus collecting and cleaning the garbage on the ground.

[0087] Continue reading Figure 6 As shown, it can be understood that the cleaning equipment 100 also includes a sludge channel 113, a blower, and a wastewater tank, so that during operation, the blower can absorb the garbage rolled up by the roller brush 131 and discharge it into the wastewater tank through the sludge channel 113.

[0088] Furthermore, the first cleaning component 130 also includes a first scraper 132, which is fixed to the side of the roller brush 131 near the walking component 120.

[0089] Specifically, when the cleaning equipment 100 moves forward, the front roller brush 131 rolls up the debris and rubs against the ground, leaving water stains on the ground. Then, the first scraper 132 at the rear of the roller brush 131 cleans up the water stains, leaving only a shallow film of water on the ground, which can dry quickly.

[0090] Continue reading Figure 7 As shown, the first cleaning component 130 further includes a scraper 133, which is mounted on the side of the roller brush 131 facing away from the scraper mechanism 142 and abuts against the roller brush 131.

[0091] Specifically, the rear end of the scraper 133 is fixed inside the body 110, and the front end abuts against the rear side of the roller brush 131, so that when the roller brush 131 moves forward, the garbage adhering to the roller brush 131 is scraped off and sucked into the sewage tank by the blower.

[0092] Continue reading Figure 8 As shown, in some embodiments, a detection mechanism 114 is provided on the side of the dirty channel 113. The control component is electrically connected to the detection mechanism 114. The detection mechanism 114 can obtain the dirt information of the dirty channel 113 and send it to the control component.

[0093] For example, the detection mechanism 114 includes an infrared emitter and an infrared receiver arranged opposite each other. The dirt channel 113 is made of transparent material, and the infrared emitter and infrared receiver are respectively arranged on two opposite sides of the dirt channel 113. Thus, during the operation of the cleaning equipment 100, the dirt channel 113 will flow with wastewater after cleaning, and the turbidity of the wastewater can effectively reflect the current cleanliness of the floor. Therefore, when the floor is relatively clean, the turbidity of the wastewater in the dirt channel 113 is low, and the infrared light emitted by the infrared emitter can effectively penetrate the dirt channel 113 and be received by the oppositely arranged infrared receiver. After the control component obtains the received signal from the infrared receiver, it determines that the current floor cleanliness is not dirty. Conversely, when the floor is not clean, the turbidity of the wastewater in the dirt channel 113 is high, and the infrared light emitted by the infrared emitter cannot effectively penetrate the dirt channel 113. The oppositely arranged infrared receiver cannot receive the infrared light signal, and after the control component obtains the unreceived signal from the infrared receiver, it determines that the current floor cleanliness is dirty.

[0094] In some embodiments, the second cleaning component 140 is mounted on the side of the roller brush 131 facing away from the walking component 120 and includes a drive mechanism 141 and a scraper mechanism 142, with the drive mechanism 141 and the scraper mechanism 142 being tractively connected. Thus, the drive mechanism 141 can drive the scraper mechanism 142 to contact or separate from the ground to cooperate with the walking component 120 and achieve various operating modes of the cleaning equipment 100.

[0095] Furthermore, the body 110 includes a first cover 111 and a second cover 112. The first cover 111 covers the side of the roller brush 131 facing away from the ground, and the second cover 112 is located on the side of the first cover 111 facing away from the roller brush 131. The scraper mechanism 142 slides and extends between the first cover 111 and the second cover 112.

[0096] Specifically, the first cover 111 is placed on top of the roller brush 131 to protect it. Simultaneously, the first cover 111 acts as a mudguard, preventing water adhering to the roller brush 131 from splashing onto the outside of the machine body 110 during its rotation. Furthermore, the first cover 111 provides a mounting platform for the second cleaning assembly 140, effectively separating it from the roller brush 131. The first cover plate covers the second cleaning assembly 140, thus providing protection for it.

[0097] Continue reading Figure 9 As shown, the drive mechanism 141 further includes a drive motor 1411, a cam, and a linkage group 1412. The drive motor 1411 is fixedly installed inside the body 110 and connected to the cam. One end of the linkage group 1412 is connected to the cam, and the other end is connected to the scraper mechanism 142. The scraper mechanism 142 is slidably engaged with the first cover 111.

[0098] For example, the drive motor 1411 can be a brushless motor, whose output is connected to the cam to drive the cam selection. The linkage assembly 1412 includes a first connecting rod 14121 and a second connecting rod 14122. The first connecting rod 14121 is rotatably connected to one side of the cam, and the other end is rotatably connected to the second connecting rod 14122. The end of the second connecting rod 14122 away from the first connecting rod 14121 is rotatably connected to the scraper mechanism 142, and the scraper mechanism 142 is slidably engaged with the first cover 111 in the direction of gravity. Thus, driven by the drive motor 1411, the cam sequentially drives the first connecting rod 14121 and the second connecting rod 14122 to rotate and retract. The scraper mechanism 142, constrained by the first cover 111, cannot rotate with the cam and can only move in the direction of gravity to achieve the extension and retraction of the scraper mechanism 142, allowing the scraper mechanism 142 to contact or separate from the ground.

[0099] It should be noted that the start of the drive motor 1411 can also be controlled by the control component, so that when the control component determines that the ground is too dirty, the start of the drive motor 1411 is restricted, and the second scraper 1422 remains separated from the ground.

[0100] Continue reading Figure 10 As shown, further, the scraper mechanism 142 includes a bracket 1421, a second scraper 1422, and at least one guide rib 1423. The second scraper 1422 is fixed to the lower end of the bracket 1421 in the direction of gravity. Each guide rib 1423 is arranged parallel to the direction of gravity and fixed to the side of the bracket 1421 facing away from the second scraper 1422. The first cover 111 is provided with at least one sliding groove 1111 parallel to the direction of gravity, and each sliding groove 1111 is distributed and slidably engaged with a corresponding guide rib 1423.

[0101] For example, two guide ribs 1423 and two slide grooves 1111 are provided to ensure the smooth movement of the scraper mechanism 142 during movement. During the operation of the drive motor 1411, the connecting rod assembly 1412 pulls the bracket 1421 to move. Under the restriction of the guide ribs 1423 and the slide grooves 1111, the bracket 1421 can only move along the extension direction of the slide grooves 1111, thereby driving the second scraper 1422 fixed to the bottom of the bracket 1421 to extend and retract up and down.

[0102] Continue reading Figure 11 As shown, the first cover 111 is further provided with a first limiting rib 115 and a second limiting rib 116 that are relatively distributed, and the bracket 1421 is limited between the first limiting rib 115 and the second limiting rib 116.

[0103] Specifically, both the first limiting rib 115 and the second limiting rib 116 extend along the length of the bracket 1421 and are distributed vertically relative to each other. It can be understood that the projection of the first limiting rib 115 in the direction of gravity is the first projection plane, the projection of the second limiting rib 116 in the direction of gravity is the second projection plane, and the projection of the top surface of the bracket 1421 in the direction of gravity is the third projection plane. These three projection planes overlap in the same area. Thus, when the bracket 1421 rises to the set position, it is blocked by the first limiting rib 115; when it descends to the set position, it is blocked by the second limiting rib 116, achieving precise positioning of the second scraper 1422.

[0104] Continue reading Figure 12 As shown, embodiments of this application also provide a cleaning method using the cleaning device 100 in any of the above embodiments.

[0105] Continue reading Figure 13 As shown, in some embodiments, the cleaning method includes:

[0106] S101, the control component determines that the dirt information of the dirt channel 113 is not dirty according to the signal of the detection mechanism 114, and the drive motor 1411 can operate normally.

[0107] S201, Cleaning equipment 100 enters the first operating mode.

[0108] Specifically, the first operating mode can be a garbage cleaning mode. The cleaning equipment 100 moves forward, the drive motor 1411 stops, and the scraper mechanism 142 is controlled to separate from the ground. The garbage to be cleaned can be rolled up by the roller brush 131 through the gap between the second scraper 1422 and the ground. The first scraper 132 follows to clean the water stains left on the ground by the roller brush 131, realizing the normal cleaning of the garbage on the ground without the garbage being blocked by the second scraper 1422.

[0109] Furthermore, the distance between the scraper mechanism 142 and the ground is d, and satisfies: d≥10mm.

[0110] For example, the distance d between the scraper mechanism 142 and the ground can be 10mm, 11mm, 12mm, 15mm, 17mm, 18mm, 19mm, etc., and can be reasonably selected according to the implementation requirements. No specific limitation is made here. In this way, through the above design, the distance between the scraper mechanism 142 and the ground is such that the garbage to be cleaned can pass through and then be rolled up by the roller brush 131.

[0111] Continue reading Figure 14 As shown, in some other embodiments, the cleaning method further includes:

[0112] S101, the control component determines that the dirt information of the dirt channel 113 is not dirty according to the signal of the detection mechanism 114, and the drive motor 1411 can operate normally.

[0113] S202, Cleaning equipment 100 enters the second operating mode.

[0114] Specifically, the second operating mode is the floor cleaning mode. The cleaning device 100 moves to the rear, the drive motor 1411 starts, and the scraper mechanism 142 is controlled to contact the ground. After cleaning up the debris in the forward direction, the roller brush 131 can continue to rotate backward to mop the ground again, while the second scraper 1422 located at the front of the roller brush 131 can effectively clean up the water stains left on the ground by the roller brush 131, improving the user experience.

[0115] Continue reading Figure 15 As shown, in some other embodiments, the cleaning method further includes:

[0116] S102, the control component determines that the dirt information of the dirt channel 113 is dirty based on the signal from the detection mechanism 114, the drive motor 1411 stops, and the scraper mechanism 142 is controlled to separate from the ground.

[0117] S203, Cleaning equipment 100 enters the third operating mode.

[0118] Specifically, the second scraper 1422 will not come into contact with the ground when the cleaning equipment 100 moves in any direction, so as to avoid the ground becoming too dirty and soiling the second scraper 1422, thereby reducing later maintenance time and extending the service life of the equipment. Until the degree of dirt on the ground reaches the set requirement, the cleaning equipment 100 can be controlled to enter the first operation mode or the second operation mode.
