Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning device and a cleaning system. BACKGROUND

[0002] As a new type of cleaning household appliance, the sweeping robot is very popular with users because of its practical functions such as self-cleaning, automatic garbage dumping and automatic recharging.

[0003] The bottom of the sweeping robot is usually provided with a roller brush. During work, the sweeping robot brings the garbage into the sweeping robot through the rotation of the roller brush. However, there are often long and thin objects such as hair and pet hair on the floor. During the cleaning operation of the sweeping robot, the long and thin objects such as hair are easy to entangle on the roller brush, which reduces the cleaning effect of the roller brush and the working efficiency of the sweeping robot. CONTENT OF THE UTILITY MODEL

[0004] The main purpose of the present application is to provide a cleaning device and a cleaning system to solve the problem that the roller brush of the sweeping robot in the prior art is easy to entangle hair.

[0005] According to one aspect of the present application, a cleaning device is provided, comprising:

[0006] A machine body having a receiving cavity and a dust suction port communicating with the receiving cavity;

[0007] A dust collecting box arranged in the machine body and communicating with the dust suction port;

[0008] A cleaning member rotatably arranged in the receiving cavity about an axis thereof, and the axis of the cleaning member is inclined to the advancing direction of the machine body so that the garbage on the cleaning member moves along the axis direction of the cleaning member towards the dust suction port.

[0009] Further, the included angle θ between the axis of the cleaning member and the advancing direction of the machine body satisfies the relationship: 0° < θ < 90°.

[0010] Further, the cleaning member has a first end and a second end opposite to the first end, the first end is rotatably connected to the machine body, and the second end is a free end.

[0011] Further, along the direction from the first end to the second end, the distance between the axis of the cleaning member and the first plane where the end of the machine body along the advancing direction is located gradually increases.

[0012] Further, along the direction from the first end to the second end, the cross-sectional area of the cleaning member gradually decreases.

[0013] Further, the dust suction port is arranged close to the second end, and in a projection along the height direction of the machine body, the dust suction port overlaps at least part of the second end.

[0014] Further, the cleaning member comprises a roller brush or a roller.

[0015] Further, the bottom of the machine body is provided with a shell, and the shell has the accommodating cavity and the dust suction port.

[0016] The shell is integrally injection molded with the machine body; or,

[0017] The shell is detachably arranged at the bottom of the machine body.

[0018] Further, at least part of the cleaning member protrudes from the bottom surface of the machine body.

[0019] In another aspect, the application also provides a cleaning system comprising the cleaning device.

[0020] Since the axis of the cleaning member in the application is arranged to be inclined to the advancing direction of the machine body, thus, during the movement of the machine body along the advancing direction to perform the cleaning operation, a frictional force along the axis direction of the cleaning member will be generated, when the garbage (such as hair and other long objects, linear garbage, strip-shaped garbage, particles, etc.) is wound on the cleaning member, the garbage will move on the cleaning member along the axis direction of the cleaning member under the action of the friction force with the ground, so as to move towards the dust suction port under the action of the frictional force generated on the cleaning member, and then the garbage will leave from the dust suction port and enter the dust collecting box, avoiding the situation that the garbage is always wound on the cleaning member, effectively improving the cleaning effect of the cleaning member, and to a certain extent, ensuring the working efficiency of the cleaning device.

[0032] As described in the background, in the cleaning process of the existing sweeping robot, the hair is easy to entangle on the roller brush, thereby adversely affecting the cleaning effect of the roller brush, resulting in low working efficiency of the sweeping robot. For this reason, the inventors of the present application designed a new type of cleaning device which can solve the problem that the roller brush of the sweeping robot in the prior art is easy to entangle hair, and the cleaning device of the present application will be described in detail below in combination with the drawings.

[0033] Referring to Figures 1 to 5 As shown, according to the embodiments of the present application, a cleaning device is provided, which comprises a body 10, a cleaning element 20 and a dust collecting box 30.

[0034] Wherein, the body 10 has a receiving cavity 101 and a suction port 102 communicating with the receiving cavity 101; the dust collecting box 30 is arranged in the body 10 and communicates with the suction port 102; the cleaning element 20 is rotatably arranged in the receiving cavity 101 around its axis, and the axis of the cleaning element 20 is arranged obliquely to the advancing direction of the body 10 so that the garbage on the cleaning element 20 moves along the axis direction of the cleaning element 20 towards the suction port 102. It should be noted that the "advancing direction of the body 10" in the present application refers to the direction indicated by the letter X in the figure. Figure 3

[0035] In the present embodiment, the receiving cavity 101 serves as a structure for receiving and mounting the cleaning element 20, and the cleaning element 20 can rotate in the receiving cavity 101 to sweep the surface to be cleaned. During the operation of the cleaning device, as the cleaning element 20 rotates, the cleaning element 20 can sweep the garbage such as hair on the ground and other surfaces to be cleaned into the receiving cavity 101, and then the garbage (such as long slender objects such as hair, linear garbage, strip-shaped garbage, particulate matter, etc.) in the receiving cavity 101 will exit from the suction port 102 and enter the dust collecting box 30. At the same time, since the axis of the cleaning element 20 in the present embodiment is arranged obliquely to the advancing direction of the body 10, thus, during the movement of the body 10 in the advancing direction to perform the cleaning operation, a frictional force along the axis direction of the cleaning element 20 will be generated on the cleaning element 20, and when the garbage (such as long slender objects such as hair, linear garbage, strip-shaped garbage, particulate matter, etc.) is wound on the cleaning element 20, the garbage will move on the cleaning element 20 along the axis direction of the cleaning element 20 under the action of the frictional force with the ground, and then move towards the suction port 102 under the action of the frictional force generated on the cleaning element 20, and then the garbage will exit from the suction port 102 and enter the dust collecting box 30, avoiding the situation that the garbage is always wound on the cleaning element 20, effectively improving the cleaning effect of the cleaning element 20, and to some extent, ensuring the working efficiency of the cleaning device.

[0036] ​In other words, the inclined cleaning component 20 in this embodiment can change the movement path of the garbage on the cleaning component 20. Compared with the case in the prior art where the axis of the cleaning component is set perpendicular to the forward direction of the machine body, since the axis of the cleaning component 20 in this embodiment is not perpendicular to the forward direction of the machine body 10, a frictional component force along its own axis will be generated on the cleaning component 20 during the forward movement of the machine body 10. When hair and other garbage come into contact with the inclined cleaning component 20, the garbage will not wrap around the cleaning component in circles as it would when it comes into contact with the vertically set cleaning component in the prior art. Instead, it will slide on the surface of the cleaning component 20 along the frictional component force generated on the cleaning component 20 in this embodiment and move towards the suction port 102. Then it will leave from the suction port 102. Alternatively, some hair may be rolled in and then fall off the cleaning component 20 due to the rotation and tilt angle of the cleaning component 20 before leaving from the suction port 102. The entire structure reduces the possibility of garbage always wrapping around the cleaning component 20, effectively improves the cleaning effect of the cleaning component 20, and to a certain extent ensures the working efficiency of the cleaning device.

[0037] It should be noted that the body 10 in this embodiment also has a vacuum pump and other suction mechanism. This suction mechanism is connected to the dust collection box 30, thereby providing suction to the suction port 102 to suck the hair and other debris in the accommodating cavity 101 into the dust collection box 30.

[0038] Further, see Figure 3As shown, in this embodiment, the angle θ between the axis of the cleaning component 20 and the forward direction of the body 10 satisfies the relationship: 0° < θ < 90°, for example, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc. When θ equals 0°, that is, when the axis of the cleaning component 20 is perpendicular to the forward direction of the body 10, the rotation direction of the cleaning component 20 is the same as the forward direction of the body 10. This causes the garbage in contact with the cleaning component 20 to wrap around the cleaning component 20 as it rotates continuously, reducing the cleaning effect of the cleaning component 20, increasing the load on the cleaning component 20, and shortening the service life of the cleaning component 20. When θ equals 90°, that is, when the axis of the cleaning component 20 is parallel to the forward direction of the body 10, the rotation direction of the cleaning component 20 is perpendicular to the forward direction of the body 10. This makes it difficult for the cleaning component 20 to effectively push the garbage forward and collect it during operation, reducing the working efficiency of the cleaning device. In other words, by ensuring that the angle θ between the axis of the cleaning component 20 and the forward direction of the body 10 satisfies the relationship: 0° < θ < 90°, it is possible to ensure that after hair and other debris are wrapped around the cleaning component 20, they will slide on the surface of the cleaning component 20 along the frictional force generated on the cleaning component 20 and leave from the suction port 102, or that some debris will be rolled in and then fall off the cleaning component 20 due to the rotation and tilt angle of the cleaning component 20 before leaving from the suction port 102, thus effectively improving the cleaning effect of the cleaning component 20.

[0039] Further, see Figure 3 As shown, the cleaning component 20 in this embodiment has a first end 201 and a second end 202 opposite to the first end 201. The first end 201 is rotatably connected to the body 10, and the second end 202 is a free end. It should be noted that in this embodiment, "the second end 202 of the cleaning component 20 is a free end" means that the second end 202 of the cleaning component 20 is suspended and not connected to the body 10, and the second end 202 of the cleaning component 20 does not serve to fix the cleaning component 20.

[0040] Specifically, since the axis of the cleaning component 20 in this embodiment is inclined to the forward direction of the body 10, and the second end 202 of the cleaning component 20 is a free end, when the cleaning component 20 gets entangled with hair and other debris during rotation, the hair and other debris will slide along the axis of the cleaning component 20 and are more likely to fall off from the free end. Compared with the structure of the cleaning component 20 with both ends fixed on the body 10, the cleaning component 20 with a free end reduces the possibility of hair and other debris remaining on the cleaning component 20, effectively ensuring the cleaning effect of the cleaning component 20.

[0041] Further, see Figure 3As shown, in this embodiment, along the direction from the first end 201 to the second end 202, the axis of the cleaning component 20 and the first plane (as shown in the attached figure) where the end of the body 10 along its own forward direction are located are intersected. Figure 3 The distance between plane A (as the first plane) gradually increases. That is to say, in this embodiment, the cleaning component 20 is tilted away from the first plane.

[0042] Specifically, in this embodiment, the first end 201 is closer to the end of the body 10 along its own forward direction than the second end 202. Thus, during the process of the body 10 moving along the forward direction to perform cleaning operations, a frictional component force is generated on the cleaning component 20 along its own axis and toward the second end 202. When the cleaning component 20 is entangled with hair or other debris, the hair is less likely to accumulate at the first end 201 and moves toward the second end 202 under the action of this frictional component force. This makes it easier for the hair and other debris to detach from the cleaning component 20 and be captured by the suction port 102 and collected into the dust collection box 30.

[0043] Further, see Figure 5 As shown, in this embodiment, the cross-sectional area of ​​the cleaning component 20 (the area of ​​the cross section obtained by cutting the cleaning component 20 along the direction from the first end 201 to the second end 202) gradually decreases.

[0044] Specifically, since the cross-sectional area of ​​the second end 202 in this embodiment is smaller than that of the first end 201, and the axis of the cleaning component 20 is inclined to the forward direction of the body 10, when hair or other debris is wrapped around the cleaning component 20, the hair or other debris will more easily slide off from the second end 202 or be thrown off as the cleaning component 20 rotates and be captured by the suction port 102 and collected into the dust collection box 30, instead of always being wrapped around the first end 201 with a larger cross-sectional area. This reduces the probability that hair is always wrapped around the cleaning component 20, effectively avoids the residue of hair or other debris on the cleaning component 20 and in the accommodating cavity 101, ensures the cleaning effect of the cleaning component 20, and improves the working efficiency of the cleaning device to a certain extent.

[0045] Further, see Figure 3 As shown, in this embodiment, the suction port 102 is located near the second end 202, and within the projection along the height direction of the body 10, the suction port 102 overlaps with at least a portion of the second end 202. It should be noted that the "height direction of the body 10" in this application refers to the attached... Figure 4 The direction indicated by the letter Y.

[0046] Specifically, because the suction port 102 in this embodiment is close to the second end 202 and overlaps with it, hair and other debris are more easily collected by the suction port 102 when the cleaning component 20 rotates. When the machine body 10 moves in the forward direction to perform cleaning operations, hair and other debris, after becoming entangled on the cleaning component 20, will move towards the second end 202 under the action of frictional force. The suction port 102 can promptly capture hair and other debris, preventing them from accumulating on the cleaning component 20 or falling back onto the surface to be cleaned, effectively improving the hair collection efficiency of the cleaning device. At the same time, it also significantly shortens the time that hair and other debris remain on the cleaning component 20, effectively preventing repeated entanglement and ensuring the cleaning ability of the cleaning component 20, thus extending the service life of the cleaning device to a certain extent.

[0047] Furthermore, the cleaning component 20 in this embodiment includes a roller brush or a roller. Since roller brushes and rollers have good cleaning effects and high durability, when used as the cleaning component 20, they can withstand a certain amount of friction and pressure during normal cleaning, ensuring the service life of the cleaning component 20. For example, the roller brush in this embodiment includes a rubber-bristled brush, a pure rubber brush, or a pure bristle brush.

[0048] Specifically, the cleaning component 20 in this embodiment includes a roller brush, the outer surface of which is provided with multiple bristle groups, which are spaced apart circumferentially along the roller brush. When the cleaning device performs cleaning operations, the rotation of the roller brush drives the bristle groups to rotate, thereby drawing debris from the ground into the receiving cavity 101. Since there is usually hair and other trash on the ground, this hair and other trash will also be drawn into the receiving cavity 101 and wrapped around the bristle groups. At this time, since the axis of the cleaning component 20 in this embodiment is inclined to the forward direction of the machine body 10, the hair and other trash wrapped around the bristle groups will move along the axial direction of the cleaning component 20 toward the second end 202 of the cleaning component 20, and then be sucked into the dust collection box 30 from the suction port 102, preventing the cleaning component 20 from being jammed due to too much hair and other trash, and ensuring that the cleaning component 20 can work normally.

[0049] It is understood that each bristle assembly in this embodiment includes multiple bristles, which extend from the first end 201 to the second end 202 of the cleaning component 20, and the multiple bristles are distributed in a spiral or straight line on the outer surface of the cleaning component 20. This ensures that bristles participate in cleaning along the entire length of the cleaning component 20, increasing the cleaning area. At the same time, the arrangement of multiple bristles can distribute the pressure on each bristle, extending the service life of the bristles to a certain extent.

[0050] Further, see Figures 2 to 3As shown, in this embodiment, the bottom of the body 10 is provided with a housing 40, which has a receiving cavity 101 and a dust suction port 102; wherein, the housing 40 is integrally injection molded with the body 10 or the housing 40 is detachably disposed at the bottom of the body 10.

[0051] In other words, in one embodiment of this application, the housing 40 and the body 10 are integrally injection molded, resulting in a stable and reliable structure that effectively improves the overall structural strength and service life of the body 10. In another embodiment of this application, the housing 40 is detachably disposed at the bottom of the body 10, facilitating disassembly and maintenance and reducing repair costs. Exemplarily, the housing 40 and the body 10 in this embodiment can be connected by snap-fit, welding, or screwing.

[0052] Further, see Figure 4 As shown, at least a portion of the cleaning component 20 in this embodiment protrudes from the bottom surface of the body 10.

[0053] Specifically, when at least part of the cleaning component 20 protrudes from the bottom surface of the body 10, it can better penetrate into the crevices of surfaces such as bottoms and tabletops, thereby removing dust, hair, and other debris from these crevices and effectively improving the cleaning efficiency of the cleaning device. At the same time, the protruding design helps to distribute the pressure between the cleaning component 20 and the surface to be cleaned, reducing the problem of hair entanglement caused by prolonged close contact.

[0054] As can be seen from the above embodiments, the cleaning device of this application, by setting the axis of the cleaning component 20 to be inclined to the forward direction of the body 10, can generate a frictional component force on the cleaning component 20 along its own axis and toward the second end 202 during the movement of the body 10 in the forward direction. When hair and other debris are wrapped around the cleaning component 20, the hair and other debris will move toward the second end 202 along the axis of the cleaning component 20 under the action of the frictional component force, and be sucked into the dust collection box 30 from the suction port 102, preventing hair and other debris from always being wrapped around the cleaning component 20, improving the cleaning effect of the cleaning component 20, and effectively ensuring the normal operation of the cleaning device.

[0055] On the other hand, embodiments of this application also provide a cleaning system that includes the aforementioned cleaning device, and therefore, the cleaning system encompasses all the technical effects of the aforementioned cleaning device. Since the technical effects of the cleaning device have already been described in detail above, they will not be repeated here.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0058] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
