Description

Technical Field

[0001] This disclosure relates to a self-moving cleaning robot, belonging to the field of cleaning equipment technology. Background Technology

[0002] Household cleaning equipment is used to clean a room by sucking up particles such as dust from the floor.

[0003] Existing household cleaning equipment may include a mop that can be coated with cleaning liquid, thereby enabling wet cleaning of the surface to be cleaned when the mop is rotated, thus improving the cleaning effect of the surface to be cleaned.

[0004] To collect cleaning liquid after wet mopping surfaces, existing household cleaning equipment typically includes a wastewater tank and uses this tank to store wastewater generated during the floor cleaning process.

[0005] After prolonged use of household cleaning equipment, dirt particles from the wastewater will accumulate in the wastewater tank and adhere to its surface. Therefore, users need to clean the wastewater tank regularly.

[0006] Existing wastewater tanks are generally designed with a detachable structure for easy periodic maintenance. However, even so, maintaining the wastewater tank is still time-consuming and laborious for users. In particular, the dirt and grime inside the tank often produces unpleasant odors, resulting in a poor user experience. Utility Model Content

Detailed Implementation

[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0031] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0033] Figure 1 This is a structural schematic diagram of a self-moving cleaning robot according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a self-moving cleaning robot according to one embodiment of the present disclosure from another angle.

[0034] The self-moving cleaning robot disclosed herein can be a sweeping robot, a mopping robot, or a combined sweeping and mopping robot, etc. The self-moving cleaning robot is capable of autonomously moving across the surface to be cleaned to clean the surface by sucking up particles located on different parts of the surface. For example... Figure 1 and Figure 2As shown, the self-moving cleaning robot disclosed herein can be a sweeping and mopping robot.

[0035] by Figure 1 and Figure 2 Taking the self-moving cleaning robot shown as an example, let's consider the robot's forward direction as "forward". Figure 2 The view direction is from above; the direction the self-propelled cleaning robot moves forward is to the side above. The direction away from the self-propelled cleaning robot's forward movement is backward. (Refer to...) Figure 2 In terms of the view direction, "behind" of a mobile cleaning robot refers to the side below. Correspondingly, the direction perpendicular to the front-back direction can be defined as the left-right direction.

[0036] When the self-moving cleaning robot is working, it can move on a roughly horizontal surface to be cleaned. The direction perpendicular to the surface is called the vertical direction (hereinafter referred to as the vertical).

[0037] The self-propelled cleaning robot may include a chassis assembly 100, which forms the body of the self-propelled cleaning robot. An auxiliary wheel assembly 400 and a driving wheel assembly 500 are provided at the bottom of the chassis assembly 100. The auxiliary wheel assembly 400 cooperates with the driving wheel assembly 500 to enable the self-propelled cleaning robot to turn. The driving wheel assembly 500 is used to drive the self-propelled cleaning robot forward or turn. The auxiliary wheel assembly 400 is located at the front of the chassis assembly 100, and the cleaning component 600 is rotatably connected to the bottom of the chassis assembly 100, thus located at the rear of the chassis assembly 100.

[0038] like Figure 2 As shown, the walking wheel assembly 500 of this disclosure can be configured as two, which are located approximately at the middle position in the front-rear direction of the chassis assembly 100 and on both sides in the left-right direction of the chassis assembly 100; and the auxiliary wheel assembly 400 is configured as one, which can be a swivel wheel, and correspondingly, the swivel wheel is located at the middle position in the left-right direction of the self-moving cleaning robot and close to the front end of the self-moving cleaning robot.

[0039] In actual use, the walking wheel assembly 500 can be driven and rotated. By controlling the walking wheel assembly 500 to rotate at a constant speed, the self-moving cleaning robot can move forward. Correspondingly, by controlling the walking wheel assembly 500 to rotate at a non-constant speed, the self-moving cleaning robot can turn.

[0040] In this disclosure, the chassis assembly 100 is further provided with a side brush assembly 200, wherein the side brush assembly 200 can be configured as one or two; Figure 2In the implementation shown, the side brush assembly 200 is configured as one, and the side brush assembly 200 is positioned on the right side of the front end of the chassis assembly 100; thereby, by rotating the side brush assembly 200, dirt on the surface to be cleaned can be disturbed, and the surface to be cleaned can be cleaned.

[0041] In addition, a brush roller assembly 300 is also provided on the chassis assembly 100. The brush roller assembly 300 is located at the middle position in the front-rear direction of the chassis assembly 100, and its length direction is the width direction of the chassis assembly 100. Thus, the brush roller assembly 300 can agitate the dirt on the surface to be cleaned. This dirt can be sucked into a dust box or other device by negative pressure adsorption, and the solid particles are separated in the dust box or other device, thereby realizing the cleaning operation of the surface to be cleaned.

[0042] In a preferred embodiment, a cleaning component 600 is further provided on the chassis assembly 100; in this disclosure, the cleaning component 600 is rotatably connected to the chassis assembly 100 and configured to make frictional contact with the surface to be cleaned to clean the surface. More preferably, when the self-moving cleaning robot is working, cleaning liquid can be provided to the cleaning component 600, thereby enabling the cleaning component 600 to perform wet mopping on the surface to be cleaned.

[0043] Figure 3 This is a structural schematic diagram of a wastewater storage device for a self-moving cleaning robot according to one embodiment of the present disclosure. Figure 4 This is a structural schematic diagram from another angle of a wastewater storage device for a self-moving cleaning robot according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the structure of a stirrer according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the structure of a storage container according to one embodiment of the present disclosure. Figure 7 This is a schematic diagram of the structure of a cover assembly according to one embodiment of the present disclosure.

[0044] like Figures 3 to 7 As shown, the self-mobile cleaning robot of this disclosure also includes a cleaning fluid storage device (not shown) and a wastewater storage device 700; the cleaning fluid storage device of this disclosure can be used to store cleaning fluid, which can be manually added to the cleaning fluid storage device by the user or automatically filled into the cleaning fluid storage device by the base station.

[0045] The cleaning fluid storage device disclosed herein can be implemented using existing technologies, which will not be described in detail here.

[0046] The cleaning fluid storage device of this disclosure is used to supply cleaning fluid to a cleaning assembly 600, which can then use this cleaning fluid to perform wet cleaning on a surface to be cleaned. After the cleaning assembly 600 performs wet cleaning on the surface to be cleaned, a certain amount of wastewater is generated, which is a mixture of dirt particles and cleaning fluid. In this disclosure, this wastewater is drawn back into a wastewater storage device 700 by negative pressure and stored therein.

[0047] When the self-propelled cleaning robot docks at the base station, it can transfer the sewage stored in the sewage storage device 700 to the base station. However, if the sewage in the sewage storage device 700 is transferred to the base station solely by gravity or by negative pressure adsorption, the dirt adhering to the inner wall of the sewage storage device 700 will not be cleaned, and consequently, the sewage storage device 700 is prone to producing odors.

[0048] The cleaning liquid storage device disclosed herein can provide cleaning liquid into the sewage storage device 700 and clean the inner wall of the sewage storage device 700 through the cleaning liquid, so that the interior of the sewage storage device 700 is in a clean state.

[0049] Specifically, the wastewater storage device 700 of this disclosure is built into the chassis assembly 100 and configured to recover a liquid mixture containing dirt particles from a surface to be cleaned. In other words, the wastewater storage device 700 is built into the chassis assembly 100 and configured to recover a liquid mixture containing dirt particles from a surface to be cleaned.

[0050] The wastewater storage device 700 includes components such as a storage container 710, a discharge port 711, a supply port 712, a stirrer 730, and a cover assembly 720.

[0051] The storage container 710 is disposed on the chassis assembly 100 and includes a bottom wall and side walls extending upward from the bottom wall; the side walls form an upward opening. Therefore, the storage container 710 of this disclosure can be used to store wastewater. Furthermore, the storage container 710 of this disclosure can be formed separately from the chassis assembly 100 or integrally, and this disclosure does not limit this.

[0052] Those skilled in the art will understand that when the storage container 710 is formed separately from the chassis assembly 100, the storage container 710 can be detached from the chassis assembly 100 to facilitate user cleaning of the storage container 710.

[0053] The cover assembly 720 is detachably disposed on the top of the storage container 710 to close the opening of the storage container 710. In a preferred embodiment, the cover assembly 720 is capable of being sealed to the storage container 710 so that wastewater can be drawn into the wastewater storage device 700 when a negative pressure is applied to the wastewater storage device 700.

[0054] The cover assembly 720 can be detachably mounted on the storage container 710, so that when the user manually cleans the wastewater storage device 700, the user can first remove the cover assembly 720 from the storage container 710, and then clean the cover assembly 720 and the storage container 710 separately, thereby cleaning the cover assembly 720 and the storage container 710 more thoroughly.

[0055] A receiving space is formed on the cover assembly 720, which extends into the storage container 710. A through hole is provided on the bottom wall of the receiving space, and a motor can be placed inside the receiving space, with the motor's output shaft passing through the through hole and located inside the storage container 710. Furthermore, a sealing structure can be provided at the location of the motor's output shaft to prevent liquid from entering the receiving space and causing damage to the motor.

[0056] A stirrer 730 is detachably mounted within the recycling tank storage container 710 and configured to be drivably rotated to stir the liquid within the storage container 710. In this disclosure, the stirrer 730 can be mounted on the output shaft of a motor and includes a plurality of stirring blades, whereby, when the motor rotates, the stirring blades can stir the liquid within the storage container 710, thereby allowing the liquid to flow through the sidewalls of the storage container 710 to flush the sidewalls of the storage container 710 with the flowing liquid.

[0057] The discharge port 711 is located at the bottom of the storage container 710 and is configured to discharge liquid to the outside of the storage container 710; that is, both the sewage stored in the storage container 710 itself and the sewage generated from cleaning the sewage storage device 700 are discharged through this discharge port.

[0058] In this disclosure, the storage container 710 includes a guide section for guiding liquid and / or debris to the bottommost end of the wastewater storage device 700. In one specific embodiment, the guide section includes a guide surface (sloping surface) located on the bottom wall of the storage container 710 and a settling tank 714, the guide surface being configured to guide dirt particles of the liquid mixture by gravity to the settling tank 714, which is located at the bottommost end of the bottom wall.

[0059] In a preferred embodiment, the sedimentation tank 714 is formed by a downward recess from the bottom wall of the storage container 710, so that when dirt settles into the sedimentation tank, it can be discharged to the outside of the wastewater storage device 700 as quickly as possible through the discharge port 711 communicating with the sedimentation tank 714. Thus, the wastewater storage device 700 of this disclosure can discharge dirt as quickly as possible, thereby reducing the number of times the wastewater storage device needs to be cleaned.

[0060] The sedimentation tank 714 is offset relative to the agitator 730, so that the agitator 730 of this disclosure can disturb the liquid in other areas without affecting the liquid discharge from the outlet 711.

[0061] A supply port 712 is provided on the cover assembly 720. Specifically, the supply port 712 is located at the top near the side wall and is configured to supply cleaning fluid into the storage container 710.

[0062] The cover assembly 720 is provided with an exhaust port 721, which can be connected to a negative pressure device. That is, negative pressure can be provided to the wastewater storage device 700 through the exhaust port 721.

[0063] In a preferred embodiment, the self-propelled cleaning robot further includes a suction device that provides negative pressure to the dust box of the self-propelled cleaning robot. The negative pressure in the dust box can be provided to the vicinity of the brush roller assembly 300, thereby collecting the dust disturbed by the brush roller assembly 300 into the dust box.

[0064] Those skilled in the art will know that a suction port may be provided on the chassis assembly 100, which is located near the rear of the brush roller assembly 300, thereby enabling the suction of a mixture of air and dirt.

[0065] In this disclosure, the exhaust port 721 can be connected to the suction port, thereby allowing negative pressure to be provided to the wastewater storage device 700 via the exhaust port 721.

[0066] In some embodiments, the wastewater storage device 700 further includes a wastewater recovery port 713, which is located at the top near the sidewall and configured to deliver a cleaning liquid containing dirt particles into the storage container 710 through the wastewater recovery port 713.

[0067] A liquid level detection device 740 is provided on the cover assembly 720, which is used to detect the liquid level in the storage container 710. In one specific embodiment, the liquid level detection device 740 can be a reed switch or a Hall element. In addition, a float 750 is provided in the sewage storage device 700, which is equipped with a magnetic element, so that the liquid level in the sewage storage device 700 can be obtained by activating the liquid level detection device 740 through the magnetic element.

[0068] The cover assembly 720 of this disclosure is further provided with a guide structure 760, which is used to guide the movement of the float 750, thereby enabling the float 750 of this disclosure to stably trigger the liquid level detection device 740.

[0069] Overall, the discharge port 711, supply port 712 and wastewater recovery port 713 of this disclosure are all located in the storage container 710, and the exhaust port 721 is located in the cover assembly 720 and near the guide structure 760, so that as little liquid as possible can enter the exhaust port 721 through the shielding of the guide structure 760.

[0070] Based on the above structure, the self-moving cleaning robot disclosed herein can realize the self-cleaning function of the sewage storage device 700, thus improving the full-chain maintenance-free system of the self-moving cleaning robot.

[0071] The self-propelled cleaning robot disclosed herein can be equipped with specific cleaning logic to achieve the self-cleaning function of a wastewater storage device. During the cleaning process, the motor drives the agitator to periodically stir the water, keeping the dirt suspended in the water. After returning to the base station, the motor first works to stir up some of the sediment, opening the discharge port to discharge the wastewater. At the same time, the supply port opens to inject clean water, realizing the discharge of dirt and the initial cleaning of the wastewater storage device. After cleaning for a certain period of time, the discharge port closes, and the exhaust port and supply port work simultaneously to fill the wastewater storage device with clean water. The motor continues to work, and after working for a certain period of time, the discharge port opens to empty the water in the wastewater storage device. The motor and discharge port are then closed, completing the self-cleaning of the wastewater storage device.

[0072] Therefore, the self-moving cleaning robot disclosed herein can achieve maintenance-free sewage storage devices, eliminating the need for users to clean them themselves and providing users with a better cleaning experience. In contrast, the existing water spray structure only sprays and cleans the sewage storage device after cleaning, but dirt still accumulates and adheres to the walls during the cleaning process, and the subsequent water spray cannot remove the stubborn dirt. This solution can periodically stir the sewage during the cleaning process, keeping the dirt suspended in the water and preventing it from accumulating and adhering to the walls.
