Description

Technical Field

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

[0002] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning equipment. They are mainly used to clean smooth floors and can automatically wet, scrub, and wipe the floor clean. The cleaning equipment uses a roller brush to contact the floor, rolling up dust, hair, and debris, which are then collected through the suction port. At the same time, the scraper wipes away water stains during the movement.

[0003] Currently, in order to improve the effect of cleaning water stains, common cleaning equipment usually adds a scraper to the rear side of the roller brush in the direction of forward movement, so as to easily scrape away the water stains left by the cleaning equipment as it moves forward.

[0004] However, current cleaning equipment often needs to be pulled back during the cleaning process, which leaves water stains on the ground. Utility Model Content

[0005] This application provides a cleaning device to solve the technical problem that current cleaning devices leave water stains on the ground when pulled back during the cleaning process.

[0006] This application provides a cleaning device, including a device body, a cleaning component, a drive mechanism, and a first scraper; the cleaning component is disposed on the device body, and the first scraper is located on the front side of the cleaning component along the cleaning direction of the cleaning device.

[0007] The drive mechanism is located on the main body of the equipment. The first scraper is connected to the drive mechanism. The drive mechanism is configured to drive the first scraper to move relative to the main body of the equipment so that the first scraper separates from the surface to be cleaned when the cleaning equipment moves forward and contacts the surface to be cleaned when the cleaning equipment is pulled backward.

[0008] The cleaning device provided in this application embodiment adds a first scraper, which is located on the front side of the cleaning component along the cleaning direction of the cleaning device. The first scraper is connected to a drive mechanism disposed on the main body of the device. The drive mechanism can drive the first scraper to move. When the cleaning device moves forward, the first scraper is driven to lift upward, facilitating the cleaning component to clean the area in front. When the cleaning device is pulled backward, the first scraper is driven to contact the surface to be cleaned downward, scraping away water stains on the surface. The first scraper is movably disposed on the front side of the cleaning component, improving cleaning efficiency.

[0009] As an optional implementation, the main body of the device has an abutment part at the front end along the cleaning direction of the cleaning device, and the first scraper is disposed below the abutment part; when the cleaning device moves forward, the first scraper part separates from the surface to be cleaned and abuts against the abutment part.

[0010] This design restricts the movement space of the first scraper. By setting a suitable abutment position, the first scraper can be blocked when it is raised to a certain height as the cleaning equipment moves forward. This prevents the first scraper from failing to remove water stains from the surface to be cleaned in time when the cleaning equipment is pulled back, or from being damaged due to collision with the surface to be cleaned because it is raised too high.

[0011] As an optional implementation, the first scraping member includes a rotating part and a scraping part. The rotating part is connected to the output end of the drive mechanism, and the scraping part is connected to the rotating part. The scraping part has a scraping strip extending towards the front of the device body.

[0012] The drive mechanism is configured to drive the rotating part to rotate, causing the scraping part to deflect toward the surface to be cleaned, so that the scraper blade contacts the surface to be cleaned, or to drive the scraping part to deflect away from the surface to be cleaned, so that the scraper blade separates from the surface to be cleaned.

[0013] With this configuration, the scraping unit, driven by the drive mechanism, can contact the surface to be cleaned and scrape away water stains with the scraper, or move away from the surface to be cleaned, facilitating the operation of the cleaning components and improving cleaning efficiency.

[0014] As an alternative implementation, the scraper has an arc-shaped segment that bends toward the bottom of the equipment body relative to the horizontal direction.

[0015] With this design, when the cleaning equipment is pulled back, the curved section of the squeegee helps the squeegee to make better contact with the ground, enhancing the cleaning effect. If the squeegee does not have the aforementioned curved section, or if the curved section is bent away from the bottom side of the main body of the equipment, water stains are easily not completely removed.

[0016] As an optional implementation, the driving mechanism includes a roller and a transmission component. The roller is rotatably mounted on the main body of the equipment. The transmission component is connected to the roller, and the first scraping component is connected to the transmission component. During the cleaning process of the cleaning equipment, the roller rolls along the surface to be cleaned and drives the transmission component to rotate, so that the transmission component drives the first scraping component to rotate.

[0017] With this configuration, when the cleaning equipment moves forward or backward, the rollers rotate, which in turn drives the transmission components to rotate. The transmission components then drive the first scraping component to rotate, causing the first scraping component to automatically lift or lower in front of the surface to be cleaned, thus improving cleaning efficiency.

[0018] As an optional implementation, the transmission component includes a first gear and a second gear, the first gear being coaxially connected to the roller, the second gear meshing with the first gear, and the first scraping component being connected to the second gear.

[0019] This setup, through gear transmission, improves the precision and stability of the transmission, ensuring that the scraping parts move along a certain trajectory and perform scraping, thereby improving cleaning efficiency and quality.

[0020] As an alternative implementation, the rotation center of the second gear is higher than the rotation center of the first gear along the height direction of the device body.

[0021] This configuration optimizes the internal space layout of the equipment, making the overall design more compact. At the same time, the increased height of the second gear provides space for the movement of the first scraping component and provides a suitable scraping angle for the scraping blade of the first scraping component, thereby improving the cleaning quality.

[0022] As an optional implementation, the first scraper has a rotational stroke. When the first scraper is in the rotational stroke, the first gear and the roller rotate synchronously. When the first scraper is at both ends of the rotational stroke and is stationary relative to the main body of the equipment, the first gear and the roller rotate relative to each other.

[0023] This design avoids unnecessary rotation of the first scraper and helps it adapt to surfaces with different slopes, improving its applicability and durability.

[0024] As an optional implementation, the first scraper is connected to a limiting bracket, the limiting bracket has a limiting part, and the main body of the equipment is provided with a snap-fit ​​part; when the first scraper rotates to abut against the main body of the equipment or the surface to be cleaned, the snap-fit ​​part engages with the limiting part.

[0025] With this configuration, the rotation range of the scraper can be precisely controlled through the cooperation of the limiting bracket and the snap-fit ​​component. At the same time, when the first scraper rotates to contact the main body of the equipment or the surface to be cleaned, the snap-fit ​​component engages with the limiting part, providing support for the first scraper and enhancing the stability of the first scraper's movement.

[0026] As an optional implementation, the limiting part includes two limiting grooves, and the snap-fit ​​member has snap-fit ​​protrusions; when the first scraping member rotates to abut against the main body of the equipment or the surface to be cleaned, the snap-fit ​​protrusions snap into the two limiting grooves respectively.

[0027] With this configuration, when the first scraper rotates to contact the main body of the equipment or the surface to be cleaned, the locking protrusion engages in the limiting groove, ensuring that the first scraper is stably limited and will not shake, thus improving the cleaning effect and enhancing stability.

[0028] As an optional implementation, the main body of the device has a movable groove, and an elastic element is provided in the movable groove. The snap-fit ​​element is movably disposed in the movable groove, and the elastic element abuts against the bottom of the movable groove between the snap-fit ​​element and the groove. The elastic element is configured to apply a force to the snap-fit ​​element toward the outside of the movable groove.

[0029] With this configuration, the elastic element can provide a resisting force for the snap-fit ​​element. When the first scraping element rotates to abut against the main body of the equipment or the surface to be cleaned, the protrusion of the snap-fit ​​element can be snapped into the limiting groove, making it less prone to loosening or displacement, thus improving the stability of the equipment.

[0030] As an optional implementation, the drive mechanism includes a drive unit and a transmission wheel. The transmission wheel is coaxially connected to the output shaft of the drive unit, and the first scraping member is connected to the transmission wheel. The drive unit is configured to drive the transmission wheel to rotate, thereby causing the first scraping member to rotate relative to the main body of the device.

[0031] This configuration allows the drive unit to directly rotate the transmission wheel, thereby causing the first scraping component to rotate relative to the main body of the equipment. This reduces the number of transmission stages and improves transmission efficiency.

[0032] As an optional implementation, the cleaning device further includes a second scraper disposed on the rear side of the cleaning assembly along the cleaning direction of the cleaning device.

[0033] With this configuration, as the cleaning equipment moves forward, the second scraper can remove residual water stains along the equipment's path, improving the cleaning effect.

[0034] As an optional implementation, the cleaning device has a receiving groove, the cleaning components are disposed in the receiving groove, the receiving groove has a first suction port on the front side along the cleaning direction of the cleaning device, and the receiving groove has a second suction port on the rear side along the cleaning direction of the cleaning device.

[0035] The first scraper is located on the side of the first suction port away from the cleaning component, and the second scraper is located on the side of the second suction port away from the cleaning component; the cleaning device also includes a third scraper, which is located between the first suction port and the cleaning component.

[0036] This setup, with two air intakes on the front and rear sides of the cleaning device and three scrapers, can more effectively collect dust and dirt from the surface to be cleaned and remove water stains, improving cleaning efficiency and effectiveness.

[0037] The cleaning device provided in this application includes a device body, a cleaning component, a drive mechanism, and a first scraper. The cleaning component is disposed on the device body, and the first scraper is located on the front side of the cleaning component along the cleaning direction of the cleaning device. The drive mechanism is disposed on the device body, and the first scraper is connected to the drive mechanism. The drive mechanism is configured to drive the first scraper to move relative to the device body, so that the first scraper separates from the surface to be cleaned when the cleaning device moves forward and contacts the surface to be cleaned when the cleaning device is pulled backward. The cleaning device provided in this application allows the first scraper to contact the surface to be cleaned when pulled backward, effectively removing water stains and improving the cleaning effect.

Therefore, they should not be construed as limitations on this application.

[0050] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0051] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0052] 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.

[0053] Floor scrubbers, vacuum cleaners, and robotic vacuum cleaners are common household cleaning equipment. They are mainly used to clean smooth floors and can automatically wet, scrub, and wipe the floor clean. The cleaning equipment uses a roller brush to contact the floor, rolling up dust, hair, and debris, which are then collected through the suction port. At the same time, the scraper wipes away water stains during the movement.

[0054] Currently, common cleaning equipment such as floor scrubbers usually have a soft rubber squeegee attached to the back of the roller brush in the forward direction to easily remove water stains left by the cleaning equipment when it moves forward. However, when the cleaning equipment is pulled back, water stains are left on the ground, and cleaning the water stains again will reduce the cleaning efficiency.

[0055] To solve the above-mentioned technical problems, this application provides a cleaning device with a movable scraper added to the front side of the cleaning device in the forward direction. The scraper can contact the surface to be cleaned when the cleaning device is pulled back to scrape off water stains on the ground and improve the cleaning effect.

[0056] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.

[0057] The cleaning equipment provided in this application embodiment is a cleaning equipment with a scraper. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, floor scrubbers, vacuum cleaners, and robot vacuum cleaners. This application embodiment does not make any specific limitation in this regard.

[0058] like Figures 1 to 3 This application provides a cleaning device 10, including a device body 100, a cleaning component 200, a drive mechanism 110 and a first scraper 120; the cleaning component 200 is disposed on the device body 100, and the first scraper 120 is located on the front side of the cleaning component 200 along the cleaning direction of the cleaning device 10.

[0059] The cleaning component 200 can be a roller brush assembly, and the driving mechanism 110 can be driven by mechanical or electric means. The first scraping member 120 is disposed on the front side of the cleaning component 200 along the cleaning direction of the cleaning device 10, and is used to scrape off the water stains left when the cleaning device 10 is pulled back.

[0060] The drive mechanism 110 is disposed on the main body 100 of the device. The first scraper 120 is connected to the drive mechanism 110. The drive mechanism 110 is configured to drive the first scraper 120 to move relative to the main body 100 of the device so that the first scraper 120 separates from the surface to be cleaned when the cleaning device 10 moves forward and contacts the surface to be cleaned when the cleaning device 10 is pulled backward.

[0061] Understandably, the drive device drives the first scraper 120 to move. When the cleaning device 10 moves forward, the first scraper 120 is driven to lift upward and move away from the surface to be cleaned, so that the cleaning component 200 can clean the front side and protect the first scraper 120. When the cleaning device 10 is pulled backward, the first scraper 120 is driven to contact the surface to be cleaned downward, so as to scrape off water stains on the surface to be cleaned and to scrape off other residues on the surface to be cleaned.

[0062] like Figure 2As an optional implementation, the main body 100 of the device is provided with an abutment portion 101 at the front end along the cleaning direction of the cleaning device 10, and the first scraper 120 is disposed below the abutment portion 101; when the cleaning device 10 moves forward, the first scraper 120 separates from the surface to be cleaned and abuts against the abutment portion 101.

[0063] It is understandable that the first scraping component 120 can be set at a suitable position below the support of the main body 100 of the equipment, with the support of the main body 100 of the equipment serving as the abutment part 101. Alternatively, a dedicated abutment part 101 can be set as needed. The space between the abutment part 101 and the surface to be cleaned is the moving space of the first scraping component 120.

[0064] like Figure 2 , Figure 3 As an optional implementation, the first scraping member 120 includes a rotating part 121 and a scraping part 122. The rotating part 121 is connected to the output end of the drive mechanism 110, and the scraping part 122 is connected to the rotating part 121. The scraping part 122 has a scraping strip 1221 extending toward the front of the device body 100.

[0065] Understandably, the rotating part 121 is the connection between the scraping member and the drive mechanism 110, responsible for converting the output of the drive mechanism 110 into the deflection motion of the scraping part 122. The scraping part 122 is connected to the rotating part 121 and includes a scraper 1221 extending towards the front of the device body 100. The scraper 1221 is the part that actually contacts the surface to be cleaned and is used to scrape away water stains and residual dirt.

[0066] The drive mechanism 110 is configured to drive the rotating part 121 to rotate, thereby causing the scraping part 122 to deflect toward the surface to be cleaned, so that the scraper 1221 contacts the surface to be cleaned, or to drive the scraping part 122 to deflect away from the surface to be cleaned, so that the scraper 1221 separates from the surface to be cleaned.

[0067] It is understood that the drive mechanism 110 is configured to drive the rotating part 121 to rotate, thereby causing the scraping part 122 to deflect toward or away from the surface to be cleaned. The drive mechanism 110 can be driven by one of the following methods: mechanical drive, electric drive, hydraulic drive, or pneumatic drive. The specific choice depends on the design requirements and cost considerations of the equipment. This application describes the embodiments using a mechanical drive approach.

[0068] As an alternative implementation, the scraper 1221 has an arcuate segment 1222 that bends toward the bottom of the device body 100 relative to the horizontal direction.

[0069] Understandably, the scraping portion 122 is not completely perpendicular to the surface to be cleaned. The design of the curved segment 1222 allows the scraping portion 122 to form a certain angle with the surface to be cleaned, ensuring the scraping effect of the scraper 1221. The design of the curved segment 1222 can be continuous, smooth, or segmented, depending on the actual application and manufacturing requirements.

[0070] like Figure 2 , Figure 3 As an optional implementation, the drive mechanism 110 includes a roller 111 and a transmission member 112. The roller 111 is rotatably mounted on the main body 100 of the device. The transmission member 112 is connected to the roller 111, and the first scraping member 120 is connected to the transmission member 112. During the cleaning process of the cleaning device 10, the roller 111 rolls along the surface to be cleaned and drives the transmission member 112 to rotate, so that the transmission member 112 drives the first scraping member 120 to rotate.

[0071] It is understood that the roller 111, as one of the core components of the drive mechanism 110, is rotatably mounted on the equipment body 100. When the equipment body 100 moves forward or backward, the roller 111 rotates, driving the transmission component 112 to rotate. The transmission component 112, as a force transmission component, transmits power to the first scraping component 120, enabling the first scraping component 120 to rotate when the equipment body 100 moves forward or backward. The transmission component 112 can be a mechanical transmission device such as a gear, chain, or belt, depending on the actual application and manufacturing requirements. This embodiment uses a gear for illustration.

[0072] As an optional implementation, the transmission component 112 includes a first gear 1121 and a second gear 1122. The first gear 1121 is coaxially connected to the roller 111, the second gear 1122 meshes with the first gear 1121, and the first scraping member 120 is connected to the second gear 1122.

[0073] The roller 111 and the first gear 1121 can be interference-fitted, and the material of the connection can be hard rubber or hard plastic. The first gear 1121 can rotate coaxially with the roller 111 or rotate relative to the roller 111.

[0074] As an optional implementation, along the height direction of the device body 100, the rotation center of the second gear 1122 is higher than the rotation center of the first gear 1121.

[0075] It is understandable that setting the rotation center of the second gear 1122 higher than the rotation center of the first gear 1121 along the height direction of the main body 100 of the equipment can optimize the internal spatial layout of the equipment, making the overall design of the equipment more compact. At the same time, the increase in the height of the second gear 1122 can provide space for the movement of the first scraping component 120 and provide a suitable scraping angle for the scraper 1221 of the first scraping component 120, thereby improving the cleaning quality.

[0076] As an optional implementation, the first scraper 120 has a rotational stroke. When the first scraper 120 is in the rotational stroke, the first gear 1121 and the roller 111 rotate synchronously. When the first scraper 120 is at both ends of the rotational stroke and is stationary relative to the main body 100, the first gear 1121 and the roller 111 rotate relative to each other.

[0077] It is understandable that, due to the force transmission method of the drive mechanism 110 in this embodiment, when the first scraping member 120 contacts the surface to be cleaned or the contact part 101, the second gear 1122 stops rotating, the first gear 1121 stops rotating accordingly, the first gear 1121 no longer follows the roller 111 to rotate, and friction occurs at the connection between the roller 111 and the first gear 1121.

[0078] For example, a rotating shaft is connected to the roller 111, and the first gear has a rotating shaft hole. The rotating shaft and the rotating shaft hole are interference-fitted. When the main body 100 of the device moves forward or backward, the torque of the roller 111 is greater than the torque of the rotating shaft. The roller 111 drives the first gear 1121 to rotate, and the first gear 1121 drives the second gear 1122 to rotate. The second gear 1122 drives the first scraper 120 to rotate. When the first scraper 120 rotates to the two ends of the rotation stroke, the abutting force of the surface to be cleaned or the abutting part 101 on the first scraper 120 is greater than the frictional force at the connection between the rotating shaft and the rotating shaft hole. Rolling friction occurs between the rotating shaft and the rotating shaft hole.

[0079] like Figure 4 , Figure 5 As an optional implementation, the first scraper 120 is connected to a limiting bracket 150, the limiting bracket 150 has a limiting part, and the device body 100 is provided with a snap-fit ​​part 160; when the first scraper 120 rotates to abut against the device body 100 or the surface to be cleaned, the snap-fit ​​part 160 engages with the limiting part.

[0080] It is understandable that by setting the limit bracket 150 and the snap-fit ​​component 160, the movement range of the first scraper 120 can be precisely controlled, and the first scraper 120 can be fixed to the position when it rotates to contact the main body of the equipment 100 or the surface to be cleaned, thereby increasing the stability of the first scraper 120.

[0081] As an optional implementation, the limiting part includes two limiting grooves 151, and the snap-fit ​​member 160 has a snap-fit ​​protrusion 161; when the first scraping member 120 rotates to abut against the device body 100 or the surface to be cleaned, the snap-fit ​​protrusion 161 snaps into the two limiting grooves 151 respectively.

[0082] It is understandable that the protrusion 161 of the snap-fit ​​member 160 and the limiting groove 151 can have the same shape. When the protrusion 161 of the snap-fit ​​member 160 is snapped into the limiting groove 151, it can fix the first scraping member 120.

[0083] As an optional implementation, the device body 100 has a movable groove 170, in which an elastic member 171 is provided. A snap-fit ​​member 160 is movably disposed in the movable groove 170. The elastic member 171 abuts against the snap-fit ​​member 160 and the bottom of the movable groove 170. The elastic member 171 is configured to apply a force to the snap-fit ​​member 160 toward the outside of the movable groove 170.

[0084] The elastic element 171 can be a spring, and the protrusion 161 of the snap-fit ​​160 can be arc-shaped. When the protrusion 161 of the snap-fit ​​160 is snapped into the limiting groove 151, the elastic element 171 applies a resisting force to the snap-fit ​​160. When the cleaning device 10 changes its moving direction, the elastic element 171 is compressed, and the protrusion 161 of the snap-fit ​​160 slides out of the limiting groove 151.

[0085] like Figure 4 As an optional implementation, the drive mechanism 110 includes a drive unit and a transmission wheel. The transmission wheel is coaxially connected to the output shaft of the drive unit. The first scraper 120 is connected to the transmission wheel. The drive unit is configured to drive the transmission wheel to rotate, thereby causing the first scraper 120 to rotate relative to the device body 100.

[0086] It is understandable that the drive mechanism 110 can directly drive the transmission wheel to rotate, causing the first scraping component 120 to rotate relative to the main body 100 of the equipment, thereby improving transmission efficiency. The drive mechanism 110 can be one of mechanical, electric, hydraulic, or pneumatic drives; the specific choice depends on the design requirements and cost considerations of the equipment.

[0087] like Figure 1 As an optional implementation, the cleaning device 10 further includes a second scraper 130, which is disposed on the rear side of the cleaning assembly 200 along the cleaning direction of the cleaning device 10.

[0088] Understandably, the second scraper 130 is used to scrape away residual water stains and dirt on the moving path of the cleaning device 10 as it moves forward.

[0089] As an optional implementation, the cleaning device 10 has a receiving groove, the cleaning component 200 is disposed in the receiving groove, the receiving groove is provided with a first suction port 102 on the front side along the cleaning direction of the cleaning device 10, and the receiving groove is provided with a second suction port 103 on the rear side along the cleaning direction of the cleaning device 10.

[0090] The cleaning component 200 may be a roller brush. The first suction port 102 is located on the front side of the cleaning component 200 along the cleaning direction and is used to suck up dust and dirt in front during the cleaning process. The second suction port 103 is located on the rear side of the cleaning component 200 along the cleaning direction and may be used to further suck up dust and dirt missed during the cleaning process or to collect dust and dirt on the cleaning component 200.
