Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, and specifically relates to a cleaning robot device. Background Technology

[0002] With the development of technology and the fast pace of life, using cleaning robots for environmental cleaning can not only improve cleaning efficiency but also free up our hands. Typically, cleaning robots have a dust collection box inside to collect the debris swept up by the cleaning device. When the dust collection box is full, the cleaning robot needs to return to the cleaning station for further dust collection, transferring the debris from the dust collection box to the cleaning station.

[0003] Currently, cleaning robots can only draw air in through the dust collection port and fan inlet during dust collection. In practical applications, since the fan inside the cleaning robot is usually located at the rear of the dust collection box, the fan inlet is also located at the rear of the dust collection box, while the dust collection port is usually located on the side of the dust collection box. In this situation, during the dust collection process, there are inevitably areas within the dust collection box that receive little or no airflow, resulting in debris remaining in those areas and thus lower dust collection efficiency of the cleaning station. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning robot device that can solve the problem of low dust collection efficiency in current cleaning base stations.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a cleaning robot device, including a cleaning base station and a cleaning robot. The cleaning base station includes a first fan, and the cleaning robot includes a robot body and a dust collection box. The dust collection box is disposed inside the robot body and has a dust collection port, a fan port, and an air inlet. The fan port and the air inlet are arranged side by side, and the air inlet is located on the side of the fan port away from the dust collection port.

[0007] When the cleaning base station is in the dust collection state, the first fan can be connected to the receiving cavity of the dust collection box through the dust collection port, and the air inlet can ventilate into the receiving cavity.

[0008] In this embodiment, the dust collection box is provided with a dust collection port, a fan port, and an air inlet. The fan port and the air inlet are arranged side by side, with the air inlet located on the side of the fan port away from the dust collection port. When the cleaning base station is in dust collection mode, the first fan can be connected to the receiving cavity of the dust collection box through the dust collection port, and the air inlet can ventilate into the receiving cavity. This solution increases the coverage area of ​​the airflow inside the dust collection box by additionally setting an air inlet at a position far from the dust collection port, so that garbage in the corners of the receiving cavity can also be collected into the cleaning base station, thereby improving the dust collection efficiency of the cleaning base station.

[0025] 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, not all, of the embodiments of this application. 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.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The cleaning robot equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] refer to Figures 1 to 10This application discloses a cleaning robot device, including a cleaning base station and a cleaning robot. The cleaning base station has a receiving space connected to the outside world, and the cleaning robot can enter the receiving space of the cleaning base station to perform operations such as dust collection, cleaning, and drying. The cleaning base station includes a first fan, optionally a blower. The cleaning robot includes a robot body and a dust collection box 100. The dust collection box 100 is disposed inside the robot body and has a dust collection port 110, a fan port 120, and an air inlet 130. The fan port 120 and the air inlet 130 are arranged side by side, and the air inlet 130 is located on the side of the fan port 120 away from the dust collection port 110. Optionally, the dust collection port 110, Both the fan inlet 120 and the air inlet 130 are located on the side wall of the dust collection box 100. The dust collection port 110 can be arranged side-by-side with the fan inlet 120, or it can be located on the side wall of the dust collection box 100, meaning the dust collection port 110 and the fan inlet 120 are located on different sides of the dust collection box 100. Alternatively, the dust collection port 110 can also be located at a corner of the dust collection box 100, i.e., at the connection point of adjacent sides. There are no specific restrictions on the arrangement of the dust collection port 110. When the cleaning base station is in dust collection mode, the first fan can be connected to the receiving cavity 140 of the dust collection box 100 through the dust collection port 110, and the air inlet 130 can ventilate into the receiving cavity 140. It should be noted that the bottom of the cleaning robot can have an opening to connect the air inlet 130 to the outside. That is to say, the air entering the receiving cavity 140 through the air inlet 130 comes from this opening and the assembly gaps between other structures of the cleaning robot.

[0029] In this embodiment, the fan port 120 and the air inlet 130 are arranged side by side, and the air inlet 130 is located on the side of the fan port 120 away from the dust collection port 110. That is, the air inlet 130 is additionally arranged at a position far away from the dust collection port 110, thereby increasing the coverage area of ​​the airflow in the dust collection box 100, so that the garbage in the corner of the containment cavity 140 can also be collected into the cleaning base station, thereby improving the dust collection efficiency of the cleaning base station.

[0030] In one optional embodiment, the cleaning robot further includes an air inlet baffle 200, which is disposed within the receiving cavity 140. The first end of the air inlet baffle 200 is detachably connected to the dust collection box 100. Optionally, the first end of the air inlet baffle 200 and the dust collection box 100 can be connected by interference fit, adhesive, torsion spring, screws, etc. The second end of the air inlet baffle 200 can rotate relative to the air inlet 130 to move closer to or further away from the air inlet 130, thereby closing or opening the air inlet 130. When the cleaning base station is in dust collection mode, the first fan can draw gas from the receiving cavity 140. At this time, the second end of the air inlet baffle 200 moves away from the air inlet 130, so that the air inlet 130 is opened, and the air inlet 130 ventilates into the receiving cavity 140. When there is no gas flow in the receiving cavity 140, the air inlet baffle 200 moves closer to the air inlet 130 under its own gravity, so that the air inlet 130 is closed, thereby preventing the leakage of garbage from the receiving cavity 140.

[0031] It should be noted that the rotation axis of the aforementioned air inlet baffle 200 extends in the horizontal direction.

[0032] Optionally, the air inlet baffle 200 can be a rigid structure, in which case the first end of the air inlet baffle 200 is rotatably connected to the dust collection box 100; or, in other embodiments, the air inlet baffle 200 is a flexible structure, optionally made of rubber, plastic, etc. The side of the air inlet baffle 200 facing away from the air inlet 130 is provided with a folding opening 210, located at the first end of the air inlet baffle 200. In this case, the second end of the air inlet baffle 200 can rotate around the folding opening 210, and the thickness at the folding opening 210 is small, making it easy to bend, so that the second end of the air inlet baffle 200 can rotate flexibly; in addition, with this structure, the first end of the air inlet baffle 200 can be detachably connected to the dust collection box 100 by means of snap-fit ​​or other methods, so as to facilitate the assembly and disassembly of the air inlet baffle 200. Of course, the air inlet baffle 200 may not have the easy-fold opening 210. In this case, the rotation flexibility of the second end of the air inlet baffle 200 is not as good as the solution of having the easy-fold opening 210 on the side of the air inlet baffle 200 away from the air inlet 130. Moreover, the rotation angle of the second end of the air inlet baffle 200 will be smaller when the easy-fold opening 210 is not provided.

[0033] Optionally, the easy-fold opening 210 may include a first sidewall and a second sidewall connected together, with an included angle between the first sidewall and the second sidewall. During the rotation of the second end of the air inlet baffle 200, the second sidewall may move closer to or further away from the first sidewall, so that the angle of the included angle changes.

[0034] In a further optional embodiment, the air inlet baffle 200 includes a blocking portion 220 with a folding opening 210. The blocking portion 220 is inclined along the air inlet direction of the air inlet 130, meaning that when there is no air flow at the air inlet 130, the distance between the second end of the blocking portion 220 and the air inlet 130 is greater than the distance between the first end of the blocking portion 220 and the air inlet 130. When there is a certain amount of airflow at the air inlet 130, the second end of the inclined blocking portion 220 is easier to rotate to move away from the air inlet 130. Of course, when there is no air flow at the air inlet 130, the blocking portion 220 can also be placed vertically. Optionally, the tilt angle of the shield 220 can be 10 to 60° to avoid it being too large to occupy a large space, and too small to be easily stuck in the air inlet 130; further alternatively, the tilt angle of the shield 220 can be 15°, and of course, it can be selected according to actual needs, and there is no specific limitation here.

[0035] Optionally, the air inlet 130 can be located near the top of the receiving cavity 140; or, the air inlet 130 can be located near the bottom of the receiving cavity 140, so that the gas entering through the air inlet 130 can more comprehensively cover the bottom of the receiving cavity 140, thereby improving dust collection efficiency. Optionally, the side wall of the receiving cavity has a limiting boss 141, which surrounds the air inlet 130 and extends to the bottom of the receiving cavity 140. The shielding portion 220 can be limited and engaged with the limiting boss 141. When the shield 220 rotates to a position close to the air inlet 130, the shield 220 engages with the limiting boss 141 to prevent further rotation and avoid the shield 220 from getting stuck in the air inlet 130. Furthermore, when there is no airflow at the air inlet 130, the shield 220 and the limiting boss 141 adhere to each other, thus preventing leakage of debris from the dust collection box 100. This is especially important when the user is disassembling or assembling the dust collection box 100, as the shield 220 needs to seal the air inlet 130. Alternatively, the limiting boss 141 can be located only at the bottom of the receiving cavity 140.

[0036] In another optional embodiment, the cleaning robot further includes a pressure plate 300, which is detachably disposed on the side wall of the receiving cavity 140 and positioned above the easy-break opening 210. That is, the pressure plate 300 avoids the easy-break opening 210 on the air inlet baffle 200 to ensure that the second end of the air inlet baffle 200 can rotate flexibly. In the air inlet direction of the air inlet 130, the pressure plate 300 presses against the edge of the air inlet baffle 200, i.e., in the air inlet direction of the air inlet 130, the edge of the pressure plate 300 overlaps with the edge of the air inlet baffle 200, so that the pressure plate 300 and the air inlet baffle 200 are in a limiting engagement to fix the first end of the air inlet baffle 200, thereby improving the stability of the second end of the air inlet baffle 200 during rotation. Of course, the first end of the air inlet baffle 200 and the side wall of the receiving cavity 140 can also be connected by fasteners.

[0037] In a further optional embodiment, the air inlet baffle 200 includes a blocking portion 220. In the air inlet direction of the air inlet 130, a pressure plate 300 presses against the edge of the blocking portion 220. That is, the first end of the blocking portion 220 can be clamped between the side wall of the receiving cavity 140 and the pressure plate 300. However, as the number of rotations of the second end of the blocking portion 220 increases, the blocking portion 220 is prone to falling off. Therefore, optionally, the side wall of the receiving cavity 140 is provided with a mounting groove 142. The air inlet baffle 200 also includes a hook portion 230, which is connected to the blocking portion 220. The hook portion 230 is located on the side of the blocking portion 220 facing the air inlet 130 and is hooked onto the mounting groove 142, thereby preventing the air inlet baffle 200 from falling off and improving the stability of the air inlet baffle 200.

[0038] In a further optional embodiment, the side wall of the receiving cavity 140 also has a fixing part 143, which is located above the air inlet baffle 200. The first end of the pressure plate 300 presses against the edge of the shielding part 220, and the second end of the pressure plate 300 is fixedly engaged with the fixing part 143. Since the air inlet baffle 200 is a flexible structure, it can deform. When the second end of the shielding part 220 rotates a large amplitude, the first end of the shielding part 220 is prone to wobbling. At this time, the stability of the entire air inlet baffle 200 is not good. In view of this, optionally, the side wall of the mounting groove 142 is provided with a clearance opening 142a, which extends to the air inlet 130. The side of the pressure plate 300 facing the mounting groove 142 has a snap-fit ​​part 310, which snaps into the clearance opening 142a. That is, the snap-fit ​​part 310 extends into the mounting groove 142 and snaps into the clearance opening 142a, thereby increasing the pressing force of the pressure plate 300 on the shielding part 220 and improving the stability of the shielding part 220. The snap-fit ​​part 310 and the hanging part 230 are arranged side by side, that is, part of the snap-fit ​​part 310 is located in the mounting groove 142, which is beneficial to improving the space utilization of the receiving groove 142.

[0039] Optionally, the thickness of the first end of the pressure plate 300 can be greater than the thickness of the second end of the pressure plate 300, thereby improving the stability of the pressure plate 300 pressing against the edge of the blocking portion 220.

[0040] Optionally, the number of the hook-on portion 230 can be one; or the number of the hook-on portion 230 can be at least two, including a first hook-on portion 231 and a second hook-on portion 232 arranged at intervals, and the snap-on portion 310 can be located between the first hook-on portion 231 and the second hook-on portion 232, so that the pressing force of the pressure plate 300 pressing on the shield 220 is located in the middle of the shield 220, thereby further improving the stability of the air inlet baffle 200.

[0041] Optionally, the fixing part 143 includes a connecting section and a limiting section connected together. One end of the connecting section is connected to the side wall of the receiving cavity 140, and the other end of the connecting section is connected to the limiting section. The limiting section is bent relative to the connecting section and is opposite to the side wall of the receiving cavity 140. That is, the limiting section, the connecting section and the side wall of the receiving cavity 140 form a snap-fit ​​groove. The second end of the pressure plate 300 is snapped into the snap-fit ​​groove, thereby fixing the second end of the pressure plate 300.

[0042] Further optionally, the number of fixing parts 143 can be one; or the number of fixing parts 143 can be at least two, including a first fixing part 143a and a second fixing part 143b arranged at intervals. In this case, the two corners of the second end of the pressure plate 300 can be fixed to the first fixing part 143a and the second fixing part 143b respectively. On the basis of ensuring the stability of the pressure plate 300, the material used to make the fixing parts 143 can be reduced.

[0043] In another optional embodiment, the dust collection box 100 includes a detachably connected box body 150 and a flip cover 160. The flip cover 160 and the box body 150 form a receiving cavity 140. Optionally, one end of the flip cover 160 is rotatably connected to the box body 150, and the other end of the flip cover 160 is snapped into place with the box body 150. When the user manually cleans the dust collection box 100, the flip cover 160 can be opened to empty the dust and clean the inner wall of the dust collection box 100. It should be noted that when the flip cover 160 is opened, its rotation axis can extend vertically. The main body 150 has a dust collection port 110, and the flip cover 160 has a fan port 120 and an air inlet 130. The first end of the air inlet baffle 200 is detachably connected to the flip cover 160, and the pressure plate 300 is detachably mounted on the flip cover 160. The air inlet baffle 200 is made of silicone, which has good thermal stability and insulation, as well as high mechanical strength. It can prevent the dust from adhering to the inner wall of the dust collection box 100 due to electrostatic force. At the same time, the silicone structure is easy to disassemble and replace. The main body 150, the flip cover 160, and the pressure plate 300 are all made of plastic, which has good insulation, is lightweight and sturdy, and is easy to process and can be mass-produced at a low price. Therefore, the main body 150, the flip cover 160, and the pressure plate 300 are made of plastic, which is not only durable but also helps to save costs. In addition, the various structures in this solution do not require welding, gluing, or threaded connections during assembly, making the installation simpler.

[0044] Optionally, the cleaning robot also includes a filter 500, which is detachably mounted at the air inlet 130 of the flip cover 160 to prevent debris from the dust collection box 100 from entering the first fan, thereby protecting the first fan. Optionally, the filter 500 can be a HEPA (High-efficiency particulate arrestance) filter, which can filter ultrafine dust particles. Optionally, the filter 500 can include a frame and a filter screen, with the filter screen mounted on the frame. The frame can be a plastic structure for easy installation and removal.

[0045] In an optional embodiment, the dust collection box 100 further includes a handle 180, the two ends of which are movably connected to the two sides of the box body 150, respectively, for easy gripping by the user. Optionally, the handle 180 can be made of plastic, which is lightweight, sturdy, and durable.

[0046] Optionally, the cleaning robot also includes a dust collection port baffle 600, which is detachably mounted on the dust collection box 100 and located outside the dust collection box 100. One end of the dust collection port baffle 600 is rotatably connected to the dust collection box 100, and the second end of the dust collection port baffle 600 is rotatable relative to the dust collection port 110 to move closer to or away from the dust collection port 110, thereby closing or opening the dust collection port 110. When the dust collection port baffle 600 moves closer to the dust collection port 110, closing the dust collection port 110, the dust collection port baffle 600 can fit against the edge of the dust collection port 110, thereby preventing the leakage of garbage from the dust collection box 100. When the first fan is turned on, under the action of airflow, the second end of the dust collection port baffle 600 moves away from the dust collection port 110, opening the dust collection port.

[0047] In one optional embodiment, the dust collection box 100 is further provided with a dust inlet 170, which is disposed opposite to the fan outlet 120. During the cleaning process of the cleaning robot cleaning the floor, the fan outlet 120 draws air, and the dust inlet 170 connects to the roller brush of the cleaning robot, so that the debris enters the dust collection box 100 from the dust inlet 170. When the cleaning station is in dust collection mode, there is a large amount of air flowing through the dust inlet 170, so that the debris in the dust collection box 100 is collected into the cleaning station. The cleaning robot also includes a dust inlet baffle 400, which is detachably disposed in the receiving cavity 140. The first end of the dust inlet baffle 400 is rotatably connected to the dust collection box 100, and the second end of the dust inlet baffle 400 can rotate relative to the dust inlet 170 to move closer to or away from the dust inlet 170, so that the dust inlet 170 is closed or opened. When there is no air flow at the dust inlet 170, the dust inlet baffle 400 moves closer to the dust inlet 170, closing the dust inlet 170 and preventing the leakage of garbage from the dust collection box 100. When there is air flow at the dust inlet 170, the dust inlet baffle 400 moves away from the dust inlet 170, opening the dust inlet 170. If the cleaning base station is in dust collection mode, then the dust inlet 170 serves as the main air inlet. If the cleaning robot is in operation, the dust inlet 170 can allow garbage to enter the dust collection box 100.

[0048] It should be noted that the rotation axis of the dust inlet baffle 400 extends horizontally so as to seal the dust collection box 100 under its own weight.

[0049] Optionally, the sidewall of the dust inlet baffle 400 contacts the sidewall of the receiving cavity 140, thereby preventing debris in the dust collection box 100 from getting stuck on the edge of the dust inlet baffle 400. Optionally, the edge of the dust inlet baffle 400 can be a right angle, in which case the sidewall of the receiving cavity 140 can be a horizontal surface, to facilitate the fabrication of the dust inlet baffle 400 and the dust collection box 100. Of course, the edge of the dust inlet baffle 400 can also be curved, in which case the sidewall of the receiving cavity 140 can also be set as a curved surface, so that the sidewall of the receiving cavity 140 matches the edge of the dust inlet baffle 400, but this will increase the fabrication difficulty of the dust collection box 100.

[0050] Optionally, the side wall of the dust collection box 100 with the dust inlet 170 can be tilted to better connect the dust inlet 170 with the roller brush of the cleaning robot, thereby improving dust collection efficiency.

[0051] Optionally, both the dust inlet baffle 400 and the dust collection baffle 600 can be made of plastic, which has good insulation, is lightweight and sturdy, easy to process and can be mass-produced, and is inexpensive.

[0052] In another optional embodiment, the receiving cavity 140 has a first arcuate sidewall 144 and a second arcuate sidewall 145 disposed opposite to each other. The first arcuate sidewall 144 extends to the air inlet 130, and the second arcuate sidewall 145 extends to the dust collection port 110, so as to make the airflow in the receiving cavity 140 smoother, reduce dead corners, and thus improve the dust collection efficiency of the cleaning base station.

[0053] Optionally, the radius of the arc of the first arc-shaped sidewall 144 can be 70mm, and the sidewall of the air inlet 130 is tangent to the first arc-shaped sidewall 144, thereby avoiding the formation of dead corners. Of course, the radius of the arc of the first arc-shaped sidewall 144 can also be other values, and this application embodiment does not impose specific limitations on this.

[0054] Optionally, the radius of the arc of the second arc-shaped sidewall 145 can be 100mm, which can be approximately perpendicular to the sidewall of the dust collection port 110 to avoid obstructing the gas flow of the dust collection port 110, thereby improving the smoothness of gas flow. Of course, the radius of the arc of the second arc-shaped sidewall 145 can also be other values, and this embodiment does not impose specific limitations on this. Further optionally, the radius of the arc of the second arc-shaped sidewall 145 can be larger, and can even be approximately planar.

[0055] Optionally, in an embodiment where the sidewall of the dust inlet baffle 400 contacts the sidewall of the receiving cavity 140, the sidewall on one side of the dust inlet 170 includes a first planar sidewall and a first arcuate sidewall 144 connected together, and the sidewall on the other side of the dust inlet 170 includes a second planar sidewall and a second arcuate sidewall 145. The two ends of the dust inlet baffle 400 contact the first planar sidewall and the second planar sidewall respectively, thereby preventing the garbage in the dust collection box 100 from getting stuck on the edge of the dust inlet baffle 400, and at the same time reducing dead corners in the receiving cavity 140 to facilitate smooth gas flow.

[0056] In an optional embodiment, the cleaning robot further includes a second fan. Optionally, the second fan can operate in two modes: a blowing mode and an exhaust mode. The second fan is connected to the fan outlet 120. When the first fan is in operating mode, i.e., the cleaning base station is in dust collection mode, the second fan is in either a shut-off mode, a blowing mode, or an exhaust mode. That is, when the first fan is in operating mode, the second fan can be in a shut-off mode, a blowing mode, or an exhaust mode. Specifically: When the second fan is in the off mode, the dust inlet 170 is the main air inlet, and a large amount of gas enters the dust collection box 100 from the dust inlet 170, while a small amount of gas enters the dust collection box 100 from the fan outlet 120 and the air inlet 130. This mode can be used when the amount of garbage in the dust collection box 100 is relatively small. When the second fan is in the blowing mode, the air intake at the dust inlet 170 and the fan outlet 120 is relatively large, while the air inlet 130 only has a small amount of air intake. This mode can be used when there is a large amount of garbage in the dust collection box 100. When the second fan is in the exhaust mode, the air intake at the dust inlet 170 will not be able to meet the exhaust volume of the dust collection outlet 110 and the fan outlet 120, so a large amount of gas needs to enter the air inlet 130. Therefore, the air intake at the dust inlet 170 and the air inlet 130 is relatively large to improve the cleaning efficiency of the corners inside the receiving cavity 140.

[0057] In other embodiments, when the first fan is in operating mode, the second fan can alternately be in at least two of the following modes: off mode, blowing mode, and exhaust mode. This allows for targeted collection of different types of waste from the dust collection box 100 and waste from different areas into the cleaning base station, thereby improving the cleaning efficiency of the cleaning base station. Optionally, when the second fan alternately is in at least two of the following modes, the duration of each mode can be the same or different, and can be flexibly set according to actual needs. This application embodiment does not impose specific limitations in this regard. Optionally, when the second fan alternately is in the following modes, the operating sequence of the three modes can be sequential or flexibly selected according to actual needs. This application embodiment also does not impose specific limitations in this regard.

[0058] In another optional embodiment, the cleaning robot also includes a third fan. When the cleaning base station is in the dust collection state, the third fan can be connected to the air inlet 130. At this time, the third fan ventilates into the accommodating cavity through the air inlet 130, thereby increasing the air intake at the air inlet 130, which is beneficial to improving the cleaning efficiency of the edge area of ​​the accommodating cavity 140.

[0059] In other embodiments, the cleaning robot also includes a water injection mechanism, which is connected to the receiving cavity 140 via the air inlet 130 to clean the receiving cavity 140, especially targeting stains adhering to the inner wall of the receiving cavity 140. Wastewater in the receiving cavity 140 can be discharged through the dust collection port 110, thereby further improving the cleanliness of the receiving cavity 140. Optionally, the water injection mechanism and the first fan can be turned on simultaneously, so that wastewater can be discharged in time, preventing excessive wastewater from overflowing from the fan port 120 and the air inlet 130 in the receiving cavity 140. Of course, the water injection mechanism and the first fan can also be turned on sequentially, and the user can choose according to actual needs. This application embodiment does not impose specific limitations on this.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
