Description

Technical Field

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

[0002] Currently, household cleaning devices such as floor sweeping robots, floor washing robots, and sweeping and mopping integrated robots have become increasingly popular, reducing the burden of human housework.

[0003] In the prior art, the existing cleaning devices have poor cleaning effects when cleaning low areas (especially low areas with a height less than 20 mm) and right-angled walls. Among them, due to the space limitation of the low area, ordinary cleaning devices are difficult to extend into the narrow space with a height less than 20 mm due to their own structural limitations, resulting in long-term accumulation of dust and dirt, affecting the overall sanitation of the home environment. In addition, when the cleaning components (such as side brushes, roller brushes, etc.) of the existing cleaning devices are close to the right-angled wall, they cannot completely fit the corner, thus forming cleaning dead corners at the wall side. These dead corners are prone to accumulating dust, hair, and stains, which not only affect the aesthetics but also may breed bacteria, posing a potential threat to human health.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0042] As mentioned in the background art, the cleaning effect of cleaning devices is poor when cleaning low areas (especially low areas with a height less than 20 mm) and right-angled walls. Among them, due to the space limitation of low areas, ordinary cleaning devices are difficult to reach into narrow spaces with a height less than 20 mm due to their own structural limitations, resulting in long-term accumulation of dust and dirt, which affects the overall sanitation of the home environment. In addition, when the cleaning components (such as side brushes, roller brushes, etc.) of existing cleaning devices are close to right-angled walls, they cannot completely fit the corners, thus forming cleaning dead corners at the walls. Dust, hair, and stains are likely to accumulate in these dead corners, which not only affects the appearance but may also breed bacteria, posing a potential threat to human health. For this reason, the present application provides a cleaning device that can solve the problem of poor cleaning effect of cleaning devices on low areas and right-angled walls in the prior art. The cleaning device of the present application will be introduced in detail below with reference to the accompanying drawings.

[0043] See Figures 1 to 10 As shown, the present application provides a cleaning device, which includes a body 10 and a cleaning assembly 20.

[0044] Specifically, a receiving groove 11 is provided on the outer side of the body 10; the cleaning assembly 20 includes a first cleaning component 22, the first cleaning component 22 is disposed on the outer peripheral side of the body 10, and the first cleaning component 22 has a first position where it descends and swings along the height direction of the body 10 and protrudes beyond the outer edge of the body 10, and the first cleaning component 22 also has a second position where it ascends and swings along the height direction of the body 10 and is received in the receiving groove 11.

[0045] In this embodiment, the cleaning assembly 20 of the cleaning device includes a first cleaning component 22. A receiving groove 11 is provided on the outer side of the body 10 of the cleaning device. The first cleaning component 22 is disposed on the outer peripheral side of the body 10, and the first cleaning component 22 has a first position where it descends and swings along the height direction of the body 10 and protrudes beyond the outer edge of the body 10 (as Figure 2 shown), and the first cleaning component 22 also has a second position where it ascends and swings along the height direction of the body 10 and is received in the receiving groove 11 (as Figure 1As shown). During actual operation, when the cleaning device detects a low area or a right-angled wall edge in front of its operation path, it controls the first cleaning component 22 to descend along the height direction of the fuselage 10 from the second position, swing, and protrude beyond the outer edge of the fuselage 10 to switch to the first position, starting to clean the low area or the right-angled wall edge. This can improve the cleaning effect of the cleaning device on the ground. After the cleaning is completed, it controls the first cleaning component 22 to ascend along the height direction of the fuselage 10, swing, and be received in the receiving groove 11, thereby switching to the second position. Receiving the first cleaning component 22 in the receiving groove 11 makes the overall fuselage 10 more regular, reduces the occupied space of the cleaning device, and facilitates storage and accommodation. In addition, the setting of the receiving groove 11 can also prevent the first cleaning component 22 from being collided or damaged when not in use, extending the service life of the cleaning device.

[0046] That is to say, in this application, by providing a receiving groove 11 and a first cleaning component 22 on the outer side of the fuselage 10, the first cleaning component 22 abuts against the fuselage 10 from within the receiving groove 11, descends along the height direction of the fuselage 10, swings, and protrudes beyond the outer edge of the fuselage 10 to clean the low area or the right-angled wall edge, improving the cleaning effect of the cleaning device on the ground. When the first cleaning component 22 finishes working, it ascends along the height direction of the fuselage 10, swings, and is received in the receiving groove 11, which can extend the service life of the first cleaning component 22 and the cleaning device.

[0047] Further, the cleaning assembly 20 further includes a second cleaning component 21, which is rotatably arranged at the bottom of the fuselage 10 and is used to clean the garbage on the surface to be cleaned (the ground or tabletop where the cleaning device is located), so that the ground reaches a clean and tidy state. Exemplarily, the second cleaning component 21 in this embodiment includes structures such as a circular mop, a roller, or a side broom, which are not specifically limited in this application.

[0048] Such as Figure 1 and Figure 2As shown, the first cleaning component 22 includes a support frame 221 and a cleaning member 222. Among them, the support frame 221 can descend and swing, or ascend and swing along the height direction of the body 10. With such a setting, the cleaning member 222 can reach different positions along with the support frame 221. When the support frame 221 descends and swings to protrude beyond the outer edge of the body 10, the cleaning member 222 can clean areas that are difficult to reach, such as the corners of walls, the edges of furniture, low areas, and the right-angled walls. When the support frame 221 ascends and swings and is received in the accommodation groove 11, it will not affect other functions of the cleaning device. The cleaning member 222 is wound around the outer periphery of the support frame 221 and can rotate along the outer periphery of the support frame 221, which can increase the friction and contact frequency between the cleaning member 222 and the ground, enhance the scrubbing effect of the cleaning member 222, and make the entire cleaning process more uniform. The rotating cleaning member 222 can also make the wear distribution more uniform, thereby extending the service life of the cleaning member 222.

[0049] Furthermore, the support frame 221 includes a support main body 2212, a driving rotating shaft 2211, and a driven rotating shaft (not shown in the figure). Among them, the support main body 2212 can be a support plate, a support block, or a support structure formed by connecting several rigid support rods, and no specific limitation is made in this application. In actual use, the support main body 2212 provides stable support for the cleaning member 222 to ensure that the first cleaning component 22 has a certain structural strength when descending or ascending. When the cleaning member 222 is working, the setting of the support main body 2212 ensures that the cleaning member 222 can maintain the correct position and shape, improving the cleaning effect. The driving rotating shaft 2211 and the driven rotating shaft are respectively arranged at opposite ends of the support main body 2212, and the axes of the driving rotating shaft 2211 and the driven rotating shaft are parallel to the surface to be cleaned (such as the ground or tabletop where the cleaning device is located) at least for driving the cleaning member 222 to rotate along the outer periphery of the support frame 221. With such a setting, the cleaning member 222 can rotate smoothly and efficiently along the outer periphery of the support frame 221. The driving rotating shaft 2211 can be connected to a power source to drive the cleaning member 222 to rotate, and the driven rotating shaft plays an auxiliary supporting and guiding role to make the rotation of the cleaning member 222 smoother, reduce the jamming and resistance during the movement of the cleaning member 222, and improve the cleaning efficiency. In addition, the driving rotating shaft 2211 and the driven rotating shaft are distributed at both ends of the support main body 2212. When the cleaning member 222 contacts the surface to be cleaned, the pressure can be evenly distributed in the length direction of the entire cleaning member 222, thereby improving the overall cleaning quality.

[0050] Further, in this embodiment, the cleaning member 222 includes a flexible track. The flexible track has an annular structure and is sleeved on the outer peripheral side of the support frame 221. The material of the flexible track in this embodiment can be cotton, fiber material, sponge material, non-woven fabric material, etc. The cleaning member 222 is set as a flexible track, which can be adaptively adjusted according to different cleaning scenarios and ground shapes during use. The flexible track can easily fit the uneven, curved or angled ground, such as the corner of a wall, the bottom of furniture, etc. Compared with a rigid cleaning member, it can cover the cleaning area more comprehensively, reduce cleaning dead corners and improve the cleaning effect. The flexible track has an annular structure and is sleeved on the outer peripheral side of the support frame 221. When the driving rotating shaft 2211 rotates, it can drive the flexible track to rotate along the outer periphery of the support body 2212 so that the flexible track performs actions such as wiping and mopping on the surface to be cleaned. This can not only increase the cleaning area of the cleaning member 222, but also improve the cleaning efficiency of the cleaning member 222, reduce the cleaning time and workload; the annular flexible track can also buffer and shock-absorb, reduce the impact of the external environment on the body 10 of the cleaning device, reduce the risk of damage to the cleaning device, and at the same time make the cleaning process more stable and reduce noise, etc.

[0051] As Figures 2 to 4 shown, the first cleaning component 22 further includes a lifting drive mechanism and a swinging drive mechanism.

[0052] Among them, the lifting drive mechanism is arranged between the first cleaning component 22 and the body 10 to drive the first cleaning component 22 to lean against the body 10 and lift along the height direction of the body 10. The setting of the lifting drive mechanism can enable the first cleaning component 22 to adapt to different cleaning scenarios, and the lifting drive mechanism can be used to adjust the contact pressure between the first cleaning component 22 and the ground according to the type of the surface to be cleaned. It can be understood that the meaning of the first cleaning component 22 leaning against the body 10 and lifting in this embodiment is that: during the rising or falling process of the first cleaning component 22, the end of the first cleaning component 22 close to the top of the body 10 always fits the edge of the body 10, that is, when the first cleaning component 22 protrudes from the edge of the body 10, the top end of the first cleaning component 22 descends along the edge of the body 10, and the bottom end of the first cleaning component 22 moves from the inside of the body 10 to the outside and protrudes from the outer edge of the body 10. Such a setting can prevent the top end of the first cleaning component 22 from tipping over and interfering or rubbing with furniture in the space, and can improve the use reliability of the cleaning device.

[0053] The swing drive mechanism is disposed between the first cleaning member 22 and the body 10 to drive the first cleaning member 22 to swing. The setting of the swing drive mechanism enables the first cleaning member 22 to fit the ground at different angles, better adapt to the shapes and slopes of various grounds, and ensure uniform cleaning effect. The swing drive mechanism can not only play a guiding role during the descent or ascent of the first cleaning member 22, but also enhance the structural stability of the first cleaning member 22, improve the working stability of the first cleaning member 22 and extend the service life of the first cleaning member 22.

[0054] As Figure 1 and Figure 2 shown, the first cleaning member 22 includes a first side 40 and a second side 41 which are oppositely arranged. The lifting drive mechanism is disposed between the first side 40 and the inner wall of the receiving groove 11, and the swing drive mechanism is disposed between the second side 41 and the inner wall of the receiving groove 11. By separately arranging the lifting drive mechanism and the swing drive mechanism between the opposite sides of the first cleaning member 22 and the inner wall of the receiving groove 11, independent and precise motion control can be achieved, and there will be no motion interference between them; such an arrangement can also balance the force and stable motion, making the force on the first cleaning member 22 more uniform during the motion. During the lifting process, the force provided by the lifting drive mechanism on the first side 40 of the first cleaning member 22 can be evenly distributed on one side of the first cleaning member 22, and during the swing process, the force applied by the swing drive mechanism on the second side 41 of the first cleaning member 22 can also act evenly on the other side of the first cleaning member 22, avoiding the first cleaning member 22 from tilting, shaking or twisting due to uneven force, and ensuring the stability and reliability of the motion of the first cleaning member 22. In addition, such an arrangement can also optimize the space utilization and structural compactness of the cleaning device.

[0055] Further, the lifting drive mechanism includes a first driving member (not shown in the figure), a rack 224 and a gear 223. Among them, when the first cleaning member 22 is in the second position, the driving rotating shaft 2211 is located at the top of the support frame 221. The first driving member is connected to the driving rotating shaft 2211 to drive the driving rotating shaft 2211 to rotate, and drive the driven rotating shaft and the cleaning member 222 to rotate synchronously; the rack 224 is disposed in the receiving groove 11 and extends along the height direction of the body 10; the gear 223 is fixedly sleeved on the driving rotating shaft 2211 and meshes with the rack 224. With such an arrangement, the rack 224 is disposed in the receiving groove 11, and the gear 223 is fixedly sleeved on the driving rotating shaft 2211, making the layout of the entire lifting drive mechanism relatively compact and effectively utilizing the space inside the cleaning device.

[0056] In addition, the first driving member drives the active rotating shaft 2211 to rotate. Through the meshing transmission between the gear 223 and the rack 224, the rotational motion of the active rotating shaft 2211 is converted into the lifting motion of the first cleaning member 22 in the height direction of the fuselage 10. This transmission method has high transmission efficiency, can accurately realize the lifting action of the first cleaning member 22, and the meshing transmission between the gear 223 and the rack 224 has high precision and reliability, which can ensure the stability and accuracy of the first cleaning member 22 during the lifting process, and reduce shaking and deviation. The first driving member can not only drive the active rotating shaft 2211 to drive the cleaning member 222 to rotate for cleaning work, but also realize the lifting function of the first cleaning member 22 through the gear 223 - rack 224 mechanism, achieving the integration of multiple functions by one driving member, simplifying the driving system of the cleaning device, and reducing the cost and failure rate. In addition, the structures of the gear 223 and the rack 224 are relatively simple, easy to manufacture and install, and are convenient for maintenance and replacement when a failure occurs. Exemplarily, the first driving member in this embodiment includes driving structures such as a driving motor.

[0057] Furthermore, as Figures 3 to 6 shown, the rack 224 is fixedly arranged on the inner wall surface of the accommodating groove 11, so that the rack 224 meshes with the gear 223, and by driving the active rotating shaft 2211 to rotate with the first driving member to drive the gear 223 to move relative to the rack 224, the top end of the first cleaning member 22 can be made to fit the fuselage 10 for lifting, avoiding the situation of the top end of the first cleaning member 22 flipping, and the service life of the first cleaning member 22 can be extended.

[0058] As Figure 2As shown, the swing drive mechanism includes a connecting rod 225. One end of the connecting rod 225 is connected to the fuselage 10, and the other end of the connecting rod 225 is connected to the first cleaning component 22. In this embodiment, one end of the connecting rod 225 can be fixedly connected to the fuselage 10, and the other end of the connecting rod 225 can be fixedly connected to the first cleaning component 22, specifically connected to the support frame 221. Among them, when the first cleaning component 22 descends along the height direction of the fuselage 10, blocked by the surface to be cleaned and coordinated with the connecting rod 225, the connecting rod 225 drives the first cleaning component 22 to swing (specifically, the bottom end of the first cleaning component 22 moves from the inner side to the outer side of the fuselage 10) to protrude beyond the outer edge of the fuselage 10, which can flexibly adjust the cleaning range and improve the cleaning effect of the cleaning device; in addition, the connecting rod 225 can also play a guiding role and strengthen the structural stability of the first cleaning component 22 when it descends to the first position. When the first cleaning component 22 ascends along the height direction of the fuselage 10, the connecting rod 225 drives the first cleaning component 22 to swing and be received in the receiving groove 11. When the first cleaning component 22 finishes the cleaning work and ascends along the height direction of the fuselage 10, it can be cleverly stored in the fuselage 10, maintaining the overall compactness and aesthetics of the fuselage 10, and also facilitating the storage and transportation of the cleaning device.

[0059] Exemplarily, the connecting rod 225 in this embodiment can be one, two or more. There is no specific limitation in this application. As long as it is other deformed structures (such as a pull rope, etc.) that can drive the first cleaning component 22 to swing during the lifting and lowering process of the first cleaning component 22, they are all within the protection scope of this application. The case where the connecting rod 225 is one is shown in the drawings of this application.

[0060] Furthermore, the swing drive mechanism further includes a second driving member (not shown in the figure). The second driving member is arranged on the fuselage 10. The second driving member is connected to the connecting rod 225, and the second driving member drives the connecting rod 225 to expand and contract to drive the first cleaning component 22 to abut against the fuselage 10 and switch from the first position to the second position. Exemplarily, the second driving member in this embodiment can be a driving motor or a driving cylinder and other structures. In some embodiments of this application, one end of the connecting rod 225 is rotatably connected to the support frame 221, and a chute extending along the height direction of the fuselage 10 is arranged on the fuselage 10. A slider that can slide along the length direction of the chute is arranged in the chute. The slider is driven by the second driving member (not shown in the figure), and at the same time, the other end of the connecting rod 225 is rotatably connected to the slider. With such an arrangement, when the second driving member drives the slider to slide along the length direction of the chute, it can drive the connecting rod 225 to move, and further drive the first cleaning component 22 to switch from the first position to the second position.

[0061] Specifically, when it is necessary to switch the first cleaning component 22 to the second position, the second driving member is used to drive the slider to move towards the top of the fuselage 10. During this process, the side of the first cleaning component 22 provided with the gear 223 rises along the height direction of the fuselage 10 relative to the rack 224, and the connecting rod 225 drives the first cleaning component 22 to rotate and be received in the accommodating groove 11. When it is necessary to switch the first cleaning component 22 to the first position, the second driving member is used to drive the slider to move towards the bottom of the fuselage 10. During this process, the side of the first cleaning component 22 provided with the gear 223 descends along the height direction of the fuselage 10 relative to the rack 224. When the bottom end of the first cleaning component 22 descends to contact the surface to be cleaned, under the blocking action of the connecting rod 225 and the surface to be cleaned, it can drive the first cleaning component 22 to rotate and protrude beyond the outer edge of the fuselage 10. Of course, in other embodiments of the present application, the second driving member may not be provided, and the first cleaning component 22 may be driven by the first driving member described above to be switched between the first position and the second position.

[0062] That is to say, in actual design, when the present application realizes the conversion of the first cleaning component 22 from the first position to the second position, two recovery methods can be adopted: First, the second driving member is not provided, and the first driving member is relied on to drive the active rotating shaft 2211 to rotate, so that the gear 223 and the rack 224 are engaged to achieve rising. At this time, the main function of the connecting rod 225 is for guiding and enhancing the structural stability. Second: The second driving member is provided to independently drive the connecting rod 225 to achieve expansion and contraction, and the gear 223 and the rack 224 are engaged so that the first cleaning component 22 rises and swings along the height direction close to the fuselage 10 and is received in the accommodating groove 11. Setting the second driving member can accurately control the position conversion of the first cleaning component 22, improve the automation degree of the device, enhance the cleaning effect, and protect the fuselage 10 and the first cleaning component 22 from damage, etc.

[0063] As Figures 7 to 10 shown, the cleaning device further includes a front wheel set 30. Within the projection in the height direction of the fuselage 10, the rotation axis of the front wheel set 30 (i.e., Figure 10 the dotted line in) is perpendicular to the forward direction of the fuselage 10, and the first cleaning component 22 is arranged at the position where the rotation axis intersects the outer edge of the fuselage 10. With such a setting, it can not only ensure that the first cleaning component 22 can clean the wall edge or the low area along a path perpendicular to the forward direction, but also ensure that the first cleaning component 22 can cover the edge areas on both sides when the fuselage 10 moves forward, effectively avoiding cleaning dead corners and improving the comprehensiveness of cleaning.

[0064] When the first cleaning component 22 is located at the intersection of the rotation axis and the outer edge of the fuselage 10, during the movement of the fuselage 10, the first cleaning component 22 can clean the ground with a relatively reasonable movement trajectory. Compared with being set at other positions, the first cleaning component 22 covers a larger cleaning area per unit time, reducing the number and time of movement of the fuselage 10, thereby improving the overall cleaning efficiency. By setting the first cleaning component 22 at the intersection of the rotation axis and the outer edge of the fuselage 10, when the first cleaning component 22 encounters an obstacle or is impacted by an external force, the front wheel set 30 can play a certain buffering and protective role, thereby extending the service life of the device.

[0065] The rotation axis of the front wheel set 30 is perpendicular to the forward direction of the fuselage 10, and the first cleaning component 22 is set at a specific position, which helps to balance the force on the fuselage 10 during the cleaning process. When the first cleaning component 22 works, the force generated by it is connected to the fuselage 10 through the rotation axis, making the center of gravity distribution of the fuselage more reasonable, reducing the shaking or deviation of the fuselage 10 caused by the work of the first cleaning component 22, and improving the stability of the device during the cleaning process.

[0066] It can be known from the above embodiments that the cleaning device of the present application can at least achieve the following technical effects:

[0067] (1) In the present application, a receiving groove is provided on the outer side of the fuselage of the cleaning device, and a first cleaning component is provided on the outer peripheral side of the fuselage. The first cleaning component has a first position where it descends along the height direction of the fuselage and swings out beyond the outer edge of the fuselage, and a second position where it rises along the height direction of the fuselage and swings into the receiving groove. The first cleaning component can solve the cleaning problem of right-angle walls, and the first cleaning component can also extend to low-lying areas, thereby improving the cleaning effect of the cleaning device.

[0068] (2) In the present application, by setting the first cleaning component at the intersection of the rotation axis of the front wheel set and the forward direction of the fuselage, the cleaning area of the first cleaning component is increased, and the cleaning effect of the first cleaning component on right-angle walls or low-lying areas is improved.

[0069] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0070] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0071] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
