Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a cleaning device. Background Technology

[0002] Vacuum cleaners, floor scrubbers and other cleaning devices are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning devices can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, cleaning devices typically use a roller brush to scrub the surface to be cleaned. During the scrubbing process, the roller brush absorbs the wastewater from the surface to be cleaned. The wastewater can be carried to the wastewater tank in the cleaning device by squeezing the roller brush and using airflow to complete the wastewater recycling.

[0004] However, a wet roller brush is prone to producing an odor. Utility Model Content

[0005] This application provides a cleaning device to solve the technical problem that current roller brushes easily produce odors when they are wet.

[0006] This application provides a cleaning device, comprising:

[0007] The device body has a first suction port and a second suction port at its bottom; along the cleaning direction of the cleaning device, the first suction port is located in front of the second suction port.

[0008] The first scraping component is movably disposed at the bottom of the main body of the device and located in front of the first suction port along the cleaning direction of the cleaning device;

[0009] The second scraping assembly is movably disposed at the bottom of the main body of the device and located behind the second suction port along the cleaning direction of the cleaning device;

[0010] A drive assembly is disposed on the main body of the device and connected to a first scraping assembly and a second scraping assembly. The drive assembly is configured to drive one of the first scraping assembly and the second scraping assembly to rise relative to the main body of the device while driving the other of the first scraping assembly and the second scraping assembly to fall relative to the main body of the device, so that one of the first scraping assembly and the second scraping assembly contacts the surface to be cleaned below the main body of the device while the other has a gap between itself and the surface to be cleaned.

[0011] The cleaning device provided in this application has two suction ports and two scraper assemblies. The scraper assemblies can scrape the surface to be cleaned, removing water stains and adhering debris. The suction ports can suck in water stains and debris. The two scraper assemblies are connected to a drive assembly. When the cleaning device is moved forward or backward, the drive assembly can drive one scraper assembly away from the surface to be cleaned, allowing debris to pass through, while the other scraper assembly contacts the surface to be cleaned to scrape it. When the cleaning device is moved forward or backward, both suction ports can suck in water stains and debris from the surface to be cleaned. The cooperation of the two suction ports and the two scraper assemblies can effectively clean the surface to be cleaned, avoiding the problem of odor that is easily generated when using a roller brush.

[0012] As an optional implementation, the bottom of the device body is provided with two vertically penetrating movable slots, and the first scraping component and the second scraping component are respectively inserted into the two movable slots; the first scraping component and the second scraping component move vertically relative to the device body.

[0013] With this configuration, the first and second scraping components can come into contact with or move away from the surface to be cleaned, in order to scrape the surface or remove debris.

[0014] As an optional implementation, the drive assembly includes a drive unit and a connecting rod. The drive unit is connected to the main body of the device, and the connecting rod is connected to the output end of the drive unit. The connecting rod is also connected to the first scraping assembly and the second scraping assembly.

[0015] The drive unit drives the linkage to rotate, so that the linkage drives the first scraping assembly and the second scraping assembly to move simultaneously, and the first scraping assembly and the second scraping assembly move in opposite directions.

[0016] With this configuration, the drive unit can drive the first scraping assembly and the second scraping assembly to move in opposite directions vertically via the linkage, so that one of the first scraping assembly and the second scraping assembly is always in contact with the surface to be cleaned, while the other maintains a distance from the surface to be cleaned.

[0017] As an optional implementation, the first end of the connecting rod is connected to the first scraping assembly, the second end of the connecting rod is connected to the second scraping assembly, and the rotation center of the connecting rod is located between the first end and the second end of the connecting rod.

[0018] With this configuration, the first and second scraping components can move synchronously via a connecting rod.

[0019] As an optional implementation, the first scraping assembly is provided with a first connecting part, the first end of the connecting rod is provided with a first sliding groove, the first connecting part is slidably connected to the first sliding groove, and the extending direction of the first sliding groove has an angle with the moving direction of the first scraping assembly.

[0020] The second scraping assembly is provided with a second connecting part, and the second end of the connecting rod is provided with a second sliding groove. The second connecting part is slidably connected to the second sliding groove, and the extension direction of the second sliding groove has an angle with the moving direction of the second scraping assembly.

[0021] This design allows the slide to absorb installation errors and dynamic deformations, preventing rigid interference from affecting the service life of the transmission mechanism.

[0022] As an optional implementation, there are two drive components, which are respectively disposed at both ends of the width direction of the device body; the first scraping component and the second scraping component both extend along the width direction of the device body, and their ends are respectively connected to the two drive components; the two drive components synchronously drive one of the first scraping component and the second scraping component to rise, and drive the other to fall.

[0023] With this configuration, the first and second scraping components can be moved synchronously through two drive components.

[0024] As an optional implementation, the driving component includes a first driving module and a second driving module. The first driving module is disposed opposite to the first scraping component and is used to drive the first scraping component to move vertically. The second driving module is disposed opposite to the second scraping component and is used to drive the second scraping component to move vertically.

[0025] With this configuration, the first and second scraping components can move synchronously through the first and second drive modules.

[0026] As an optional implementation, the first scraping assembly includes a first body and a first scraping strip. The first scraping strip is connected to the lower end of the first body. The device body is provided with a first limiting part. After the driving assembly drives the first scraping assembly to lift, the upper end of the first body abuts against the first limiting part.

[0027] The second scraping assembly includes a second body and a second scraping strip. The second scraping strip is connected to the lower end of the second body. The main body of the device is provided with a second limiting part. After the driving assembly drives the second scraping assembly to rise, the upper end of the second body abuts against the second limiting part.

[0028] This design limits the movement of the scraper blade by using a limiting part and the surface to be cleaned to prevent excessive travel.

[0029] As an optional implementation, the main body of the device is connected to a movable wheel, and the main body of the device moves along the surface to be cleaned by the movable wheel; the cleaning device also includes a detection module and a controller, the detection module is arranged opposite to the movable wheel, the detection module is configured to detect the rotation direction of the movable wheel; the detection module is electrically connected to the controller, the controller is configured to receive the detection signal from the detection module and control the action of the drive components;

[0030] When the moving wheel rolls forward along the cleaning direction of the cleaning device, the controller controls the drive component to drive the first scraping component to rise and the second scraping component to fall; when the moving wheel rolls backward, the controller controls the drive component to drive the second scraping component to rise and the first scraping component to fall.

[0031] With this configuration, the lifting or lowering of the first and second scraping components can be controlled during the movement of the cleaning device, improving the ease of control.

[0032] As an optional implementation, the cleaning device also includes a water spray assembly connected to the bottom of the device body and located between the first suction port and the second suction port; the water spray assembly extends along the width direction of the device body and is configured to spray water downwards from the device body to wet the surface to be cleaned.

[0033] This setup, by wetting the surface to be cleaned with a water spray component, can improve the cleaning effect.

[0034] This application provides a cleaning device, including a device body, a first scraping assembly, a second scraping assembly, and a driving assembly. Both the first and second scraping assemblies are movably disposed at the bottom of the device body. The bottom of the device body also has a first suction port and a second suction port. Along the cleaning direction of the cleaning device, the first scraping assembly, the first suction port, the second suction port, and the second scraping assembly are arranged sequentially. The driving assembly is disposed on the device body and connected to the first and second scraping assemblies. The driving assembly is configured to drive the first and second scraping assemblies to move synchronously vertically in opposite directions, such that one of the first and second scraping assemblies contacts the surface to be cleaned below the device body while the other maintains a distance from the surface.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Vacuum cleaners, floor scrubbers and other cleaning devices are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning devices can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0049] In related technologies, cleaning devices typically use a roller brush to scrub the surface to be cleaned. During the scrubbing process, the roller brush absorbs the wastewater from the surface to be cleaned. The wastewater can be carried to the wastewater tank in the cleaning device by squeezing the roller brush and using airflow to complete the wastewater recycling.

[0050] However, roller brushes are difficult to clean thoroughly after cleaning and need to be dried; otherwise, they are prone to producing odors when damp.

[0051] To address the aforementioned technical problems, this application provides a cleaning device comprising two scraping components, two suction nozzles, and a driving component. Driven by the driving component, one of the scraping components is kept in contact with the surface to be cleaned to scrape away stubborn stains and adhered debris. The other component is raised and kept at a distance from the surface to be cleaned, allowing debris to pass through. The scraping components and the two suction nozzles work together to effectively clean the surface. After cleaning, the scraping components and suction nozzles are easy to clean and do not produce odors.

[0052] The application scenarios of the cleaning device provided in the embodiments of this application will be illustrated below.

[0053] The cleaning device in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, robot vacuums, etc. Depending on the product type, the cleaning device provided in this application embodiment can be used to clean various types of ground, floors, etc., and this application embodiment does not make specific limitations in this regard.

[0054] Figure 1 This is a schematic diagram of the cleaning device provided in the embodiments of this application; Figure 2 for Figure 1 A magnified view of part A in the middle; Figure 3 for Figure 2 A magnified view of part B in the middle section; Figure 4 This is a schematic diagram of the bottom structure of the cleaning device provided in an embodiment of this application.

[0055] Reference Figures 1 to 4 As shown, this application provides a cleaning device 100, including a device body 110, a first scraping assembly 120, a second scraping assembly 130, and a drive assembly 160. Both the first scraping assembly 120 and the second scraping assembly 130 are movably disposed at the bottom of the device body 110. The bottom of the device body 110 also has a first suction port 140 and a second suction port 150. Along the cleaning direction of the cleaning device 100, the first scraper assembly 123, the first suction port 140, the second suction port 150, and the second scraping assembly 130 are arranged sequentially, with the first scraper assembly 123 located at the foremost side and the second scraper assembly 133 located at the rearmost side. The first suction port 140 and the second suction port 150 are located between the first scraper assembly 123 and the second scraper assembly 130. The three components are arranged such that the first suction port 140 is adjacent to the first scraper 123 component, and the second suction port 150 is adjacent to the second scraper 133 component; the drive component 160 is disposed on the device body 110 and connected to the first scraper component 120 and the second scraper component 130; the drive component 160 is configured to drive one of the first scraper component 120 and the second scraper component 130 to rise relative to the device body 110, while driving the other of the first scraper component 120 and the second scraper component 130 to fall relative to the device body 110, so that one of the first scraper component 120 and the second scraper component 130 contacts the surface to be cleaned below the device body 110, while the other has a gap from the surface to be cleaned.

[0056] Understandably, when the cleaning device 100 moves on the surface to be cleaned, the drive assembly 160 can drive one of the first scraper 123 assembly and the second scraper 133 assembly to make interference contact with the surface to be cleaned, so as to scrape off water stains and sticky debris from the surface to be cleaned. The other assembly has a gap with the surface to be cleaned, so that debris can pass through the gap and be sucked in by the first suction port 140 or the second suction port 150 and collected in the waste collection device of the device body 110.

[0057] For example, when the first scraper 123 component contacts the surface to be cleaned, the second scraper 133 component moves away from the surface. Debris and debris pass through the gap between the second scraper 133 component and the surface, and are first sucked in by the second suction port 150 near the second scraper 133 component. The remaining debris, as well as debris, water stains, and cleaning wastewater scraped by the first scraper 123 component, can be sucked in by the first suction port 140 near the first scraper 123 component. Conversely, when the second scraper 133 component contacts the surface to be cleaned, the first scraper 123 component moves away from the surface. Debris and debris pass through the gap between the first scraper 123 component and the surface, and are first sucked in by the first suction port 140 near the first scraper 123 component. The remaining debris, as well as debris, water stains, and cleaning wastewater scraped by the second scraper 133 component, can be sucked in by the second suction port 150 near the second scraper 133 component. The cooperation of the two suction ports and the two scraper components can effectively clean the surface, avoiding the problem of odors that are easily generated when using a roller brush.

[0058] It should be noted that the first scraper 123 assembly and the second scraper 133 assembly are arranged parallel to each other and both extend along the width direction of the device body 110. The length of the first scraper 123 assembly and the second scraper 133 assembly matches the width of the device body 110. When the cleaning device 100 moves, the cleaning range of the first scraper 123 assembly and the second scraper 133 assembly can cover the moving path of the device body 110, avoiding cleaning omissions.

[0059] Reference Figure 4 The cleaning direction of the cleaning device 100 is defined as the Y direction, and the width direction of the device body 110 is defined as the X direction, which is perpendicular to the Y direction.

[0060] As one possible implementation, the bottom of the device body 110 is provided with two vertically penetrating movable slots 111, and the first scraping component 120 and the second scraping component 130 are respectively inserted into the two movable slots 111; the first scraping component 120 and the second scraping component 130 move vertically relative to the device body 110.

[0061] It is understood that both movable slots 111 extend along the width direction of the device body 110 and match the width of the device body 110. When the first scraping assembly 120 and the second scraping assembly 130 move vertically relative to the device body 110, the two movable slots 111 can limit the first scraping assembly 120 and the second scraping assembly 130 to prevent them from shifting during movement.

[0062] In some embodiments, the drive assembly 160 includes a drive unit 161 and a connecting rod 162. The drive unit 161 is connected to the device body 110, and the connecting rod 162 is connected to the output end of the drive unit 161. The connecting rod 162 is simultaneously connected to the first scraping assembly 120 and the second scraping assembly 130. The drive unit 161 drives the connecting rod 162 to rotate, so that the connecting rod 162 drives the first scraping assembly 120 and the second scraping assembly 130 to move simultaneously, and the moving directions of the first scraping assembly 120 and the second scraping assembly 130 are opposite.

[0063] It should be noted that there can be one connecting rod, and the connecting rod 162 can be connected to the middle of the first scraping assembly 120 and the second scraping assembly 130 in the length direction at the same time, so that the lower edges of the first scraping assembly 120 and the second scraping assembly 130 remain parallel during the movement; there can also be multiple connecting rods, with multiple connecting rods 162 arranged in parallel and connected to different positions in the length direction of the first scraping assembly 120 and the second scraping assembly 130 at the same time, so that the lower edges of the first scraping assembly 120 and the second scraping assembly 130 remain parallel during the movement.

[0064] In one possible implementation, the first end 1621 of the connecting rod 162 is connected to the first scraping assembly 120, the second end 1622 of the connecting rod 162 is connected to the second scraping assembly 130, and the rotation center of the connecting rod 162 is located between the first end 1621 and the second end 1622 of the connecting rod 162.

[0065] It is understood that the rotation center of the connecting rod 162 is connected to the output shaft of the drive unit 161. After the drive unit 161 is started, the output shaft of the drive unit 161 drives the rotation center of the connecting rod 162 to rotate, so that the first end 1621 and the second end 1622 of the connecting rod 162 rotate. The included angle between the first end 1621 and the second end 1622 of the connecting rod 162 can be 180 degrees or not. When the connecting rod 162 rotates, both the first end 1621 and the second end 1622 of the connecting rod 162 have an offset in the vertical direction, and the first end 1621 and the second end 1622 move in opposite directions in the vertical direction, so that the first scraping assembly 120 and the second scraping assembly 130 can move synchronously and in opposite directions.

[0066] As one possible implementation, the first scraping assembly 120 is provided with a first connecting part 121, and the first end 1621 of the connecting rod 162 is provided with a first sliding groove 1623. The first connecting part 121 is slidably connected to the first sliding groove 1623, and the extension direction of the first sliding groove 1623 forms an angle with the moving direction of the first scraping assembly 120. The second scraping assembly 130 is provided with a second connecting part 131, and the second end 1622 of the connecting rod 162 is provided with a second sliding groove 1624. The second connecting part 131 is slidably connected to the second sliding groove 1624, and the extension direction of the second sliding groove 1624 forms an angle with the moving direction of the second scraping assembly 130.

[0067] It is understandable that by sliding the first groove 1623 and the second groove 1624 at both ends of the connecting rod 162 with the first connecting part 121 and the second connecting part 131, the rotational motion of the connecting rod 162 can be converted into the opposite linear motion of the first scraping assembly 120 and the second scraping assembly 130. When the drive unit 161 drives the connecting rod to rotate, the first groove 1623 and the second groove 1624 at fixed angles will force the first connecting part 121 and the second connecting part 131 to slide along the first groove 1623 and the second groove 1624 respectively. Due to the restriction of the sliding groove, the first connecting part 121 and the second connecting part 131 will move in the vertical direction. This sliding connection method can also automatically compensate for assembly errors.

[0068] In some embodiments, there are two drive components 160, which are respectively disposed at both ends of the device body 110 in the width direction; the first scraping component 120 and the second scraping component 130 both extend along the width direction of the device body 110, and their ends are respectively connected to the two drive components 160; the two drive components 160 synchronously drive one of the first scraping component 120 and the second scraping component 130 to rise and drive the other to fall.

[0069] It is understood that both drive components 160 include drive units 161 and connecting rods 162. The two connecting rods 162 are arranged in parallel and are respectively located at both ends of the width direction of the device body 110. Both ends of the two connecting rods 162 are respectively connected to the first scraping component 120 and the second scraping component 130. The two drive units 161 can be controlled by the control system to operate synchronously, so that the two ends of the first scraping component 120 and the second scraping component 130 can remain synchronized during the movement.

[0070] In some embodiments, the driving component 160 includes a first driving module and a second driving module. The first driving module is disposed opposite to the first scraping component 120 and is used to drive the first scraping component 120 to move vertically. The second driving module is disposed opposite to the second scraping component 130 and is used to drive the second scraping component 130 to move vertically.

[0071] For example, both the first drive module and the second drive module include a drive unit 161 and a telescopic rod. One end of each telescopic rod is connected to the output end of the two drive units 161, and the other end of each telescopic rod is connected to the first connecting part 121 and the second connecting part 131, respectively. The drive assembly 160 may also be provided with a control system. The control system controls the two drive units 161 to synchronously drive the two telescopic rods to move in the vertical direction to extend and retract according to the movement of the cleaning device 100, that is, according to the rotation of the rollers of the cleaning device 100. The control system also controls the two telescopic rods to move in opposite directions, so that when one of the first scraping assembly 120 and the second scraping assembly 130 is raised, the other is lowered.

[0072] In one possible implementation, the first scraping assembly 120 includes a first body 122 and a first scraper 123. The first scraper 123 is connected to the lower end of the first body 122. The device body 110 is provided with a first limiting part 112. After the drive assembly 160 drives the first scraping assembly 120 to rise, the upper end of the first body 122 abuts against the first limiting part 112. The second scraping assembly 130 includes a second body 132 and a second scraper 133. The second scraper 133 is connected to the lower end of the second body 132. The device body 110 is provided with a second limiting part 113. After the drive assembly 160 drives the second scraping assembly 130 to rise, the upper end of the second body 132 abuts against the second limiting part 113.

[0073] Understandably, when the first scraping assembly 120 rises, the second scraping assembly 130 falls. When the upper end of the first body 122 abuts against the first limiting part 112, the lower edge of the second scraper 133 simultaneously abuts against the surface to be cleaned. Similarly, when the second scraping assembly 130 rises, the first scraping assembly 120 falls. When the upper end of the second body 132 abuts against the second limiting part 113, the lower edge of the first scraper 123 simultaneously abuts against the surface to be cleaned.

[0074] As an optional implementation, the main body 110 of the device is connected to a movable wheel 180, and the main body 110 moves along the surface to be cleaned via the movable wheel 180. The cleaning device 100 also includes a detection module and a controller. The detection module is arranged opposite to the movable wheel 180 and is configured to detect the rotation direction of the movable wheel 180. The detection module is electrically connected to the controller, which is configured to receive the detection signal from the detection module and control the operation of the drive component 160. When the movable wheel 180 rolls forward along the cleaning direction of the cleaning device 100, the controller controls the drive component 160 to drive the first scraping component 120 to rise and the second scraping component 130 to fall. When the movable wheel 180 rolls backward, the controller controls the drive component 160 to drive the second scraping component 130 to rise and the first scraping component 120 to fall.

[0075] For example, the detection module is a Hall sensor, and the controller can be an electronic control board. When the cleaning device 100 is pulled back in the cleaning direction, the Hall sensor detects that the moving wheel 180 rotates counterclockwise. The electronic control board receives this signal and then sends a clockwise command to the drive unit 161. When the drive unit 161 drives the output shaft to rotate clockwise, it will drive the connecting rod 162 to rotate clockwise, thereby lifting the second scraping assembly 130 and lowering the first scraping assembly 120. When the upper end of the second body 132 contacts the second limiting part 113, the drive unit 161 stops driving and keeps the first scraping assembly 120 and the second scraping assembly 130 in their current positions. At this time, the second scraper 133 and the surface to be cleaned form a certain gap, and the first scraper 123 and the surface to be cleaned produce a certain interference, which can scrape the surface to be cleaned. When the cleaning device 100 moves forward in the cleaning direction, the Hall sensor detects that the moving wheel 180 is rotating clockwise and sends a command to make the connecting rod 162 rotate counterclockwise, so that the second scraper 133 makes interference contact with the surface to be cleaned, and the first scraper 123 has a certain gap with the surface to be cleaned.

[0076] As an optional implementation, the cleaning device 100 also includes a water spray assembly 170, which is connected to the bottom of the device body 110 and located between the first suction port 140 and the second suction port 150. The water spray assembly 170 extends along the width direction of the device body 110 and is configured to spray water downwards from the device body 110 to wet the surface to be cleaned.

[0077] It should be noted that the water spray assembly 170 also includes a water pump and multiple water spray holes 171. The water pump is connected to the clean water tank in the main body 110 of the device and supplies cleaning water to the multiple water spray holes 171. In some embodiments, there can be two water spray holes 171, which are located between the first suction port 140 and the second suction port 150, and at both ends of the length direction of the main body 110 of the device. When the cleaning device 100 moves and cleans the surface to be cleaned, the two water spray holes 171 continuously spray water to wet the surface to be cleaned. The first suction port 140 and the second suction port 150 can be located in the middle of the length direction of the main body 110 of the device. When the first suction port 140 and the second suction port 150 are suctioning, the water flow sprayed from the two side water spray holes 171 will move towards the middle. As the water flow moves towards the middle suction port on the ground, it can wet the surface to be cleaned, thereby improving the scraping effect of the first scraping assembly 120 or the second scraping assembly 130.

[0078] This application provides a cleaning device 100, including a device body 110, a first scraping assembly 120, a second scraping assembly 130, and a drive assembly 160. The first scraping assembly 120 and the second scraping assembly 130 are both movably disposed at the bottom of the device body 110. The bottom of the device body 110 also has a first suction port 140 and a second suction port 150. Along the cleaning direction of the cleaning device 100, the first scraper assembly 123, the first suction port 140, the second suction port 150, and the second scraping assembly 130 are arranged sequentially. The drive assembly 160 is disposed on the device body 110 and connected to the first scraping assembly 120 and the second scraping assembly 130. The drive assembly 160 is configured to drive the first scraping assembly 120 and the second scraping assembly 130 to move synchronously vertically in opposite directions, so that one of the first scraping assembly 120 and the second scraping assembly 130 contacts the surface to be cleaned below the device body 110 while the other has a gap from the surface to be cleaned. The cleaning device 100 provided in this application cleans the surface to be cleaned through a suction port and a scraper assembly, achieving good cleaning results without producing any odor.
