Abstract
Description
Technical Field
[0001] This disclosure relates to a cleaning device, belonging to the field of cleaning device technology. Background Technology
[0002] When cleaning the floor, the cleaning equipment moves along the surface to be cleaned via its moving parts. The rotating brush contacts the surface and, in conjunction with the suction of the cleaning equipment, collects the dirt into the interior of the equipment, thereby achieving the purpose of cleaning the garbage on the surface.
[0003] Currently, during the cleaning process, the moving parts of the cleaning equipment come into contact with the surface to be cleaned, which makes it easy for debris to adhere to the moving parts. Furthermore, when the cleaning equipment repeatedly passes over the cleaned surface, the debris attached to the moving parts can also cause damage to the cleaned surface, resulting in low cleaning efficiency of the cleaning equipment. Utility Model Content
[0004] This disclosure provides a cleaning device to solve the problem of low cleaning efficiency in related technologies.
[0005] To achieve the above objectives, the present disclosure adopts the following technical solution:
[0006] This disclosure provides a cleaning device, including:
[0007] The housing has an installation cavity and a dust collection port, with the installation cavity communicating with the dust collection port;
[0008] A roller brush is rotatably mounted on the housing, the roller brush is disposed in the mounting cavity, and at least a portion of the roller brush is disposed opposite to the dust collection port;
[0009] A drive unit, connected to the roller brush, is configured to drive the roller brush to rotate.
[0010] A movable element, disposed in the housing, is configured to drive the housing to move;
[0011] The housing has a first side and a second side. The direction from the second side to the first side is the direction in which the moving part drives the housing forward. The distance between the roller brush and the first side is the first distance, and the distance between the moving part and the first side is the second distance. The first distance is smaller than the second distance.
[0012] In some embodiments, the roller brush has a first end and a second end located at both ends of the roller brush axially, and the roller brush also has an annular surface located between the first end and the second end, the distance between the annular surface and the first side being a first distance.
[0013] The movable component has a movable surface that contacts the ground, and the distance between the movable surface and the first side is the second distance.
[0014] In some embodiments, the moving element includes two drive wheels with their central axes collinear, and the distance between the outer boundaries of the two drive wheels is less than the axial length of the brush.
[0015] In some embodiments, the cleaning device further includes a housing and a negative pressure element, the housing being detachably connected to the casing, the housing having a collection chamber and an exhaust passage, the collection chamber communicating with the mounting chamber, and the negative pressure element disposed in the casing and / or the housing, the negative pressure element being configured to discharge gas in the collection chamber through the exhaust passage to create a negative pressure in the collection chamber.
[0016] In some embodiments, the negative pressure component includes a fan and a filter, both of which are disposed in the housing. The fan is configured to discharge gas in the collection chamber through an exhaust passage, and the filter is configured to filter the gas discharged through the exhaust passage.
[0017] In some embodiments, the inner wall of the collection chamber is formed with a guide portion, the guide portion having a guide surface connected to the side wall of the collection chamber, the guide surface being set at an angle to the side wall of the collection chamber, so that the guide surface is configured to guide the gas in the collection chamber to the exhaust channel.
[0018] In some embodiments, the guide surface includes multiple guide segments connected sequentially along the direction from the bottom to the top of the collection cavity, with adjacent guide segments arranged at an angle.
[0019] In some embodiments, at least one of the multiple guide sections is arranged at an angle of less than 90° to the sidewall of the collection cavity.
[0020] In some embodiments, the cleaning device also includes a water delivery component, and the housing has a clean water chamber for containing cleaning fluid. The water delivery component is connected to the clean water chamber and is configured to spray the cleaning fluid in the clean water chamber onto the roller brush.
[0021] In some embodiments, the cleaning equipment also includes a detection element disposed within the housing, the detection element being configured to detect stains on the floor and to detect obstacles.
[0022] In the cleaning equipment provided in this disclosure, a roller brush is rotatably disposed within the mounting cavity of the housing, and the roller brush is positioned opposite the dust collection port of the housing. When the dust collection port is opposite the ground, the drive unit drives the roller brush to rotate, allowing the roller brush to roll along the ground and collect debris from the ground into the mounting cavity. The first gap is smaller than the second gap, ensuring that when the cleaning equipment moves, after the roller brush contacts and cleans the ground, the moving part can avoid contact with uncleaned areas, preventing debris from contaminating the roller brush. This prevents the moving part from contaminating areas already cleaned by the roller brush when it subsequently passes over them, thus improving the cleaning efficiency of the cleaning equipment of this disclosure.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0042] When cleaning the floor, the cleaning equipment moves along the surface to be cleaned via its moving parts. The rotating brush contacts the surface and, in conjunction with the suction of the cleaning equipment, collects the dirt into the interior of the equipment, thereby achieving the purpose of cleaning the garbage on the surface.
[0043] Currently, the roller brush of cleaning equipment is positioned between two rollers on the moving part, placing both the brush and rollers in the middle of the bottom of the equipment. During the cleaning process, the area cleaned by the brush cannot cover the area traversed by the rollers, causing debris to easily accumulate on the rollers. Furthermore, when the cleaning equipment repeatedly passes over the cleaned surface, the debris on the rollers can further damage the surface after the brush has swept it, resulting in low cleaning efficiency.
[0044] In the cleaning device disclosed herein, a roller brush is rotatably disposed within the mounting cavity of the housing, with the roller brush and the dust collection port of the housing facing each other. When the dust collection port is facing the ground, the driving component drives the roller brush to rotate, allowing it to roll along the ground and collect debris into the mounting cavity. A moving component drives the housing to move, enabling the roller brush to move along the ground from the second side to the first side. This allows the roller brush to collect debris from multiple areas of the ground into the mounting cavity along the direction of the housing's movement. The first gap is smaller than the second gap, ensuring that when the cleaning device moves, after the roller brush contacts and cleans the ground, the moving component, upon passing over the cleaned area, avoids contact with uncleaned areas, preventing debris from contaminating the roller brush. This ensures that the moving component will not contaminate the cleaned area when subsequently passing over it, thus improving the cleaning efficiency of the cleaning device of this disclosure.
[0045] The contents of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this disclosure.
[0046] This disclosure discloses a cleaning device, with reference to Figure 1 As shown, it includes a housing 100, a roller brush 200, a drive unit 300, and a moving part 400. Specifically, this cleaning device can be a robotic vacuum cleaner used to clean floors.
[0047] The housing 100 is the basic component of the cleaning equipment disclosed herein. The housing 100 provides a mounting base for at least some other components of the cleaning equipment and serves to protect those components. The housing 100 can be made of metal, giving it better structural strength, thus improving its durability and reliability. Alternatively, the housing 100 can be made of polymer material, achieving a certain structural strength while maintaining a relatively light weight. Furthermore, the housing 100 can also employ a structure combining some metal and some polymer materials. Specifically, the main structure of the housing 100 and parts susceptible to external impact or damage can be made of metal, while other parts can be made of polymer material. This allows the housing 100 to achieve good structural strength without excessive weight, thereby reducing the weight of the cleaning equipment.
[0048] The housing 100 has a mounting cavity 110, which is a hollow structure within the housing 100. The housing 100 also has a dust collection port 120, which is an opening on the surface of the housing 100 and communicates with the mounting cavity 110. The dust collection port 120 can be positioned opposite the ground, allowing external debris to enter the mounting cavity 110 through it.
[0049] At least a portion of the roller brush 200 is disposed in the mounting cavity 110, and the roller brush 200 is rotatably connected to the housing 100. A drive unit 300 is connected to the roller brush 200 and configured to drive the roller brush 200 to rotate. The roller brush 200 is positioned opposite the dust collection port 120. Specifically, the entire roller brush 200 can be located within the mounting cavity 110 of the housing 100, and the circumferential sidewall of the roller brush 200 located between its two ends can be positioned precisely at the dust collection port 120. Thus, when the cleaning device is placed on the ground and the dust collection port 120 is opposite the ground, the roller brush 200 can contact the ground. When the roller brush 200 rotates, it can draw debris from the ground into the mounting cavity 110.
[0050] Furthermore, the mounting cavity 110 of the housing can also be connected to the box 500, and the box 500 is provided with a collection cavity 510, which is connected to the mounting cavity 110. A negative pressure can be formed in the collection cavity 510, so that the garbage that is rolled into the mounting cavity 110 by the roller brush 200 can be sucked into the collection cavity 510, thereby concentrating the garbage in the collection cavity 510 to achieve the purpose of cleaning up the garbage on the ground and facilitating subsequent garbage disposal.
[0051] A movable element 400 is disposed on the housing 100 and configured to drive the housing 100 to move, thereby allowing the roller brush 200 and the drive element 300 disposed on the housing 100 to also move, so that the entire cleaning device can move along the ground. The housing 100 has a first side 130 and a second side 140, and the direction from the second side 140 to the first side 130 of the housing 100 is the direction in which the movable element 400 drives the housing 100 to move. Figure 1 The X direction in the middle. In this way, the entire cleaning device can move along the direction from the second side 140 to the first side 130, so that the roller brush 200 can also move along the direction from the second side 140 to the first side 130, thereby allowing the roller brush 200 to clean the ground along the direction from the second side 140 to the first side 130. The roller brush 200 can roll up the garbage in multiple areas on the ground into the mounting cavity 110 along the moving direction of the housing 100.
[0052] The distance between the roller brush 200 and the first side 130 of the housing 100 is the first distance, which is... Figure 1 The length of the dashed line M. The distance between the moving part 400 and the first side 130 of the housing 100 is the second distance, which is... Figure 1The length of the dashed line N is such that the first spacing is smaller than the second spacing. When the cleaning equipment moves, the roller brush 200 contacts and cleans the surface before the moving part 400 passes over the cleaned area. This avoids contact between the moving part 400 and uncleaned areas, preventing the roller brush 200 from being contaminated by debris. Consequently, when the moving part 400 subsequently passes over areas already cleaned by the roller brush 200, it will not contaminate the surface, thus improving the cleaning efficiency of the disclosed cleaning equipment.
[0053] Furthermore, it should be noted that because the first and second spacings are different, the roller brush 200 and the moving member 400 are spaced apart along the direction from the first side 130 to the second side 140. This ensures that the roller brush 200 and the moving member 400 will not interfere with each other in the direction perpendicular to the first side 130 to the second side 140 and perpendicular to the height direction of the housing 100. This allows the length setting of the roller brush 200 to be unaffected by the moving member 400. The length direction of the roller brush 200 is... Figure 1 In the Y direction. Correspondingly, the length of the roller brush 200 can be set to be relatively longer, so that the roller brush 200 can clean a larger floor area, further improving the cleaning efficiency of the cleaning equipment disclosed herein.
[0054] In some implementations, reference Figures 1 to 2 As shown, the roller brush 200 of this disclosure may have a first end 210 and a second end 220 located at both axial ends of the roller brush 200, with the first end 210 and the second end 220 located on opposite sides of the roller brush 200. The roller brush 200 also has an annular surface 230 located between the first end 210 and the second end 220, the annular surface 230 extending circumferentially along the roller brush 200. When the roller brush 200 rotates, the portions of the annular surface 230 of the roller brush 200 can sequentially contact the ground.
[0055] refer to Figure 2As shown, the movable component 400 has a movable surface 430 that contacts the ground. When the movable component 400 moves the housing 100 along the ground, the movable surface 430 is in contact with the ground. For example, the first distance can specifically refer to the distance between the annular surface 230 of the roller brush 200 and the first side 130 of the housing 100, and the second distance can specifically refer to the distance between the movable surface 430 of the movable component 400 and the first side 130 of the housing 100. Thus, the annular surface 230 of the roller brush 200 is closer to the first side 130 of the housing 100 than the movable surface 430 of the movable component 400. Accordingly, when the cleaning device moves along the ground, the annular surface 230 of the roller brush 200 can contact the ground to be cleaned before the movable surface 430 of the movable component 400, allowing the roller brush 200 to clean the ground first, and then the movable surface 430 of the movable component 400 passes over the ground cleaned by the roller brush 200, preventing debris from the ground from contaminating the movable surface 430 of the movable component 400.
[0056] Specifically, the movable component 400 in this disclosure can be a roller structure, and correspondingly, the movable surface 430 of the movable component 400 is the part where the bottom of the roller contacts the ground. The movable surface 430 in contact with the ground is specifically an arc segment. As an example, the second distance can specifically indicate the distance between the front end of the movable surface 430 adjacent to the first side 130 of the housing 100 and the first side 130 of the housing 100.
[0057] The movable component 400 in this disclosure can also be a track structure, and correspondingly, the movable surface 430 of the movable component 400 is the part where the bottom of the track contacts the ground. The movable surface 430 in contact with the ground is a planar segment. As an example, the second distance can specifically refer to the distance between the front end of the bottom of the track adjacent to the first side 130 of the housing 100 and the first side 130 of the housing 100.
[0058] In some implementations, reference Figure 1 As shown, the movable component 400 of this disclosure may specifically include two drive wheels 410, both of which are connected to the drive component 300, allowing the drive component 300 to drive the two drive wheels 410 to rotate synchronously. The central axes of the two drive wheels 410 are collinear. Thus, the two drive wheels 410 are located at different parts of the bottom of the housing 100, and the two drive wheels 410 can jointly drive the housing 100 to move, resulting in better stability when the cleaning equipment moves. It should be understood that one side of the bottom of each drive wheel 410 is in contact with the ground; correspondingly, the moving surface 430 of the movable component 400 is the part of the bottom of the two drive wheels 410 that is in contact with the ground.
[0059] The distance between the outer edges of the two drive wheels 410 is no greater than the axial length of the brush 200. Specifically, the distance between the outer edges of the two drive wheels 410 is... Figure 1The length of the dashed line P, and the axial length of the roller brush 200, is the distance between the first end 210 and the second end 220 of the roller brush 200, which is... Figure 1 The length of the dashed line Q. It should be understood that when the roller brush 200 contacts the ground to clean it, the width of the ground cleaned by the roller brush 200 is determined by the axial length of the roller brush 200, that is, by the length of the roller brush 200 in the Y direction. The longer the axial length of the roller brush 200, the wider the width of the ground that the roller brush 200 can clean when the cleaning equipment moves in one direction.
[0060] By ensuring that the distance between the outer edges of the two drive wheels 410 is no greater than the axial length of the roller brush 200, the area traversed by the two drive wheels 410 is cleaned by the roller brush 200 when the cleaning device moves in one direction. This prevents garbage on the ground from contaminating the drive wheels 410, and keeps the moving surface 430 of the drive wheels 410 clean, preventing the moving surface 430 of the drive wheels 410 from being contaminated by garbage and re-contaminating the cleaned ground.
[0061] In addition, refer to Figure 1 As shown, in order for the moving part 400 to drive the entire cleaning equipment to rotate, the moving part 400 may also be provided with a steering wheel 420. The steering wheel 420 and the line connecting the two driving wheels 410 can form an isosceles triangle structure. The steering wheel 420 can turn, thereby enabling the entire cleaning equipment to turn.
[0062] In some implementations, reference Figures 3 to 6 As shown, the cleaning equipment disclosed herein may also include a housing 500 and a negative pressure component 600. (Referring to...) Figure 3 , Figure 4 and Figure 6 As shown, the housing 500 is detachably connected to the shell 100. The housing 500 has a collection chamber 510 and an exhaust channel 520. The collection chamber 510 is an internal cavity structure within the housing 500, communicating with the mounting cavity 110 of the shell 100. The collection chamber 510 also communicates with the exhaust channel 520, allowing the collection chamber 510 to communicate with the external space of the housing 500 through the exhaust channel 520. (Reference) Figure 5 As shown, a negative pressure element 600 is disposed in the housing 100 and / or the box 500. The negative pressure element 600 is configured to discharge the gas in the collection chamber 510 through the exhaust channel 520, thereby creating a negative pressure in the collection chamber 510.
[0063] Specifically, the housing 100 also has an air inlet, which is an opening on the surface of the housing 100. The air inlet is connected to the mounting cavity 110, and the collection cavity 510 is connected to the mounting cavity 110 through the air inlet. This negative pressure environment in the collection cavity 510 also affects the mounting cavity 110. Waste swept into the mounting cavity 110 by the roller brush 200 can be sucked into the collection cavity 510 through the air inlet, allowing the waste to be concentrated in the collection cavity 510. When the collection cavity 510 is full of waste, the container 500 can be disassembled from the housing 100, and the waste in the collection cavity 510 can be emptied.
[0064] In some implementations, reference Figure 5 As shown, the negative pressure component 600 of this disclosure may include a fan 610, which is disposed in the housing 100. The fan 610 is configured to discharge the gas in the collection chamber 510 through the exhaust passage 520. Specifically, the housing 100 may have an opening corresponding to the exhaust passage 520 of the housing 500. When the housing 500 is installed in the housing 100, the exhaust passage 520 is also located inside the housing 100 and can communicate with the outside through the opening on the housing 100. The fan 610 may be disposed in the housing 500, specifically in the collection chamber 510 or the exhaust passage 520 of the housing 500. In this way, the fan 610 can also draw the gas in the collection chamber 510 out of the collection chamber 510 through the exhaust passage 520, so that the collection chamber 510 is under negative pressure.
[0065] Of course, in other embodiments, the fan 610 can also be provided at the opening on the housing 100 corresponding to the exhaust channel 520, so that the fan 610 can draw the gas in the collection chamber 510 out of the housing 100 through the exhaust channel 520 and the opening of the housing 100 in sequence, so as to form a negative pressure in the collection chamber 510.
[0066] refer to Figure 5 As shown, the negative pressure component 600 of this disclosure may also include a filter section 620, which is configured to filter the gas discharged through the exhaust channel 520. Specifically, when the fan 610 discharges the gas in the collection chamber 510 through the exhaust channel 520, it may also blow some garbage into the exhaust channel 520. By providing the filter section 620, this garbage can be blocked and filtered, preventing it from being discharged through the exhaust channel 520 into the collection chamber 510 and re-polluting the environment, thereby improving the cleaning efficiency of the cleaning equipment of this disclosure. The filter section 620 can be specifically provided at the exhaust channel 520 of the housing 500. Of course, the filter section 620 can also be provided at the opening on the housing 100 corresponding to the exhaust channel 520, so that the filter section 620 can filter the gas passing through the exhaust channel 520 and block garbage.
[0067] In some implementations, reference Figure 6 As shown, the inner wall of the collection cavity 510 of the housing 500 of this disclosure can be formed with a guide portion 530. The guide portion 530 is a protruding structure on the inner wall of the collection cavity 510. The guide portion 530 and the housing 500 can be integrally formed, so that the stability and reliability of the connection between the guide portion 530 and the housing 500 are better.
[0068] It should be understood that the negative pressure created inside the collection chamber 510 of the housing will also draw in the external gas-liquid mixture. In order to better separate the gas-liquid mixture and prevent the liquid portion of the gas-liquid mixture from being discharged outside the collection chamber 510 through the exhaust channel 520, the guide portion 530 may be provided with a guide surface 540. The guide surface 540 is connected to the side wall of the collection chamber 510, and the guide surface 540 is set at an angle to the side wall of the collection chamber 510, so that the guide surface 540 is configured to guide the gas in the gas-liquid mixture in the collection chamber 510 to the exhaust channel 520, and guide the liquid in the gas-liquid mixture to fall to the bottom of the collection chamber 510 under the action of gravity.
[0069] The exhaust channel 520 is a through-groove structure that penetrates the side wall of the housing 500. The exhaust channel 520 has an opening on the side wall of the collection chamber 510, and the opening of the exhaust channel 520 can be located above the guide surface 540. The guide surface 540 can be a structure that slopes from the bottom to the top of the collection chamber 510. In this way, when the gas-liquid mixture in the collection chamber 510 passes through the guide surface 540, the gas in the gas-liquid mixture can flow more efficiently to the top side of the collection chamber 510, so that the gas in the gas-liquid mixture can be discharged more efficiently through the exhaust channel 520 to the outside of the collection chamber 510.
[0070] Correspondingly, when the gas-liquid mixture passes through the guide surface 540, the liquid in the gas-liquid mixture can flow along the guide surface 540 to the bottom of the collection chamber 510 under the action of gravity, so that the liquid in the gas-liquid mixture can be concentrated at the bottom of the collection chamber 510, preventing the liquid in the gas-liquid mixture from being discharged from the exhaust channel 520 of the housing 500.
[0071] To ensure that the guide surface 540 of the guide portion 530 can effectively guide the gas in the collection chamber 510 to the exhaust channel 520, the guide portion 530 in this disclosure can be disposed circumferentially within the collection chamber 510. Correspondingly, the guide surface 540 extends circumferentially within the collection chamber 510, allowing the guide surface 540 to connect with various parts of the sidewall of the collection chamber 510 along its circumference. In this way, the gas in the gas-liquid mixture in each region of the collection chamber 510 can flow efficiently along the guide surface 540 to the exhaust channel 520 and be discharged outside the collection chamber 510 through the exhaust channel 520.
[0072] In some implementations, reference Figure 6 As shown, the guide surface 540 of this disclosure may include multiple guide segments 541, which are connected sequentially along the direction from the bottom to the top of the collection cavity 510, with adjacent guide segments 541 arranged at an angle. In this way, at least some of the guide segments 541 can extend along the direction from the bottom to the top of the collection cavity 510, thereby guiding the gas in the gas-liquid mixture to the exhaust channel 520.
[0073] For details, please refer to Figure 7 As shown, among the multiple guide sections 541, some guide sections 541 can be arranged along the direction from the bottom to the top of the collection cavity 510, while other guide sections 541 can be arranged parallel to the bottom wall of the collection cavity 510. In this way, the guide surface 540 formed by connecting multiple guide sections 541 can have a stepped structure and extend from the bottom to the top of the collection cavity 510, so that the guide surface 540 can guide the gas in the gas-liquid mixture in the collection cavity 510 to flow to the exhaust channel 520.
[0074] In addition, refer to Figure 8 As shown, any one of the multiple guide sections 541 can be set at an angle of less than 90° to the bottom wall of the collection chamber 510. In this way, all the guide sections 541 are inclined relative to the bottom wall of the collection chamber 510, and all the guide sections 541 can guide the gas in the gas-liquid mixture to the exhaust channel 520.
[0075] In some implementations, reference Figure 6 As shown, at least one of the multiple guide segments 541 of this disclosure is set at an angle of less than 90° to the side wall of the collection cavity 510, so that the guide segment 541 can form a chamfered structure, making the overall transition of the guide surface 540 smoother.
[0076] In addition, refer to Figure 9 As shown, some guide sections 541 can also be configured as arc surfaces. The surface transition of the arc surface structure guide section 541 is smoother, which makes the guide section 541 more effective in guiding the gas flow to the exhaust channel 520.
[0077] Specifically, in this disclosure, the arc-shaped guide segment 541 can be positioned between two inclined guide segments 541, thus making the connection between the two inclined guide segments 541 smoother. Of course, multiple guide segments 541 can also all be arc-shaped, and the multiple guide segments 541 can be continuous arc surfaces, or the centers of each guide segment 541 can be set differently. All of these methods can serve the purpose of guiding the gas in the gas-liquid mixture to the exhaust channel 520. The arc-shaped guide segment 541 can be a convex arc surface or a concave arc surface; this disclosure does not limit this.
[0078] In some embodiments, the cleaning equipment of this disclosure may further include a water supply component. A clean water chamber for containing cleaning fluid may be provided within the housing 500. The water supply component is connected to the clean water chamber and configured to spray the cleaning fluid from the clean water chamber onto the roller brush 200. In this way, cleaning fluid can adhere to the surface of the roller brush 200. When the roller brush 200 rotates and contacts the ground, it can adhere the cleaning fluid to the ground, thereby achieving the purpose of thoroughly cleaning the ground.
[0079] In addition, the blower 610 discharges the air in the collection chamber 510 through the exhaust channel 520, so that the collection chamber 510 forms a negative pressure, which can also draw the cleaning liquid on the ground into the collection chamber 510, so as to avoid the cleaning liquid remaining on the ground and achieve the purpose of thoroughly cleaning the ground.
[0080] In some implementations, reference Figure 1 and Figure 3 As shown, the cleaning equipment disclosed herein may also include a detection element 700 disposed in the housing 100, the detection element 700 being configured to detect stains on the ground and to detect obstacles.
[0081] Specifically, the detection component 700 can be electrically connected to the processing module of the cleaning equipment, and the moving component 400 can also be electrically connected to the processing module. The detection component 700 can detect stains and obstacles on the ground. Based on the condition of the stains, the processing module controls the moving component 400 to drive the cleaning equipment to move, allowing the cleaning equipment to pass over stained surfaces and enabling the roller brush 200 to contact and clean the surface. The processing module can also control the moving component 400 to drive the cleaning equipment to avoid obstacles based on their distribution.
[0082] The detection unit 700 may specifically include a laser detection unit 730, a camera detection unit 710, and an ultrasonic detection unit 720. The camera detection unit 710 can be used to detect stains on the ground and obstacles, the laser detection unit 730 can be used to detect obstacles, and the ultrasonic detection unit 720 can be used to detect the type of ground.
[0083] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.
[0084] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.
[0085] It should be readily understood that “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest manner, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).
[0086] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.
[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
