Description

Technical Field

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

[0002] With the development of cleaning technology, and combined with people's increasing desire to be liberated from the tedious daily cleaning tasks, in recent years, fully intelligent cleaning robots that can automatically identify obstacles have received more and more attention and application. The working principle they adopt is mainly to add intelligent obstacle recognition technology on the basis of existing automatic sweepers and vacuum cleaners, without the need for people to operate cleaning tools; and the actual core cleaning technology principle is also to set up motors for each functional module to realize the friction rotation between the broom and the ground, to realize the vacuuming of the ground by the suction port, and to realize the cleaning of the ground by the mop. These different functional modules are all independently set, and then installed in an intelligent sweeping all-in-one machine (usually set to a disc shape) through reasonable layout design, commonly known as a cleaning robot; since the structural cost of the cleaning robot is dozens or even hundreds of times the cost of pure mechanical cleaning tools such as brooms and mops, although the cleaning robot has the advantage of highly intelligent cleaning, it is obviously lacking the basis for cost saving to use it as a popular cleaning tool for people to use for daily cleaning.

[0003] Existing cleaning robots have a relatively simple mopping mode and cannot automatically adjust the mop pressure and water output according to the dirtiness and oiliness of the floor, resulting in poor mopping performance. Even some cleaning robots have automatic adjustment functions, but they usually use connecting rods and rotary pressure, which can lead to structural instability, low efficiency, and insufficient pressure.

[0004] Therefore, it is urgent to design a cleaning device and a cleaning robot to solve the technical problems of the existing cleaning devices and cleaning robots in automatically adjusting the mop pressure and the unstable water output. Summary of the Invention

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] like Figure 1 As shown, the present invention provides a cleaning device. Specifically, the cleaning device can be applied in the technical field of sweeping robots, and can also be applied to structures such as automatic cleaning machines. Here, only the cleaning robot is used as a specific embodiment for explanation. Of course, it can be understood that other cleaning household appliances are also within the scope of protection of the present invention.

[0038] Specifically, the cleaning device includes a housing 1 and a base plate 2. The housing 1 and base plate 2 are fixedly connected to form a receiving chamber. Part of the cleaning device is disposed within the receiving chamber so that the cleaning device can clean the floor. The bottom surface of the base plate 2 is provided with rollers 7 and universal wheels 5, which enable the cleaning device to be moved. A mop 6 is provided on the base plate 2 and can be brought into contact with the floor to clean the floor.

[0039] Furthermore, existing cleaning devices cannot control the cleaning intensity of the mop 6 by the degree of floor dirt. In the embodiment provided by the present invention, different mopping modes are implemented by detecting the degree of floor dirt, thereby cleaning floor dirt in a targeted manner and saving energy.

[0040] Furthermore, an identification structure is provided on the side wall of the housing 1. The identification structure can identify the degree of dirt on the floor, set three cleaning modes according to the degree of dirt on the floor, and control the cleaning device to adopt the corresponding cleaning mode to clean the floor. Of course, it is understandable that the cleaning mode can also be set to two, four, or more cleaning modes. Here, only three cleaning modes are used as a preferred embodiment. The cleaning device can be controlled according to the different set modes to achieve floor cleaning and save energy.

[0041] Furthermore, the identification structure also includes a laser radar 3, which can detect the movement trajectory and path of the cleaning device, so that the cleaning device can move according to the set path to achieve floor cleaning.

[0042] As a preferred embodiment, the recognition structure includes an AI camera 4, which is arranged on the side wall of the shell 1. The AI camera 4 is used to identify the degree of dirt on the ground, set three cleaning modes according to the degree of dirt on the ground, and control the cleaning device to adopt the corresponding cleaning mode to clean the ground. The cleaning mode provided by the present invention mainly realizes different mopping modes for floors with different degrees of dirtiness, and mainly supports three modes: automatic lifting mode, normal mopping mode, and pressurized mopping mode. The status of the cleaning device in different modes is as follows: Figure 5-10 As shown, three different cleaning modes are used to control the rotation of the water tank 8 at different angles, thereby achieving different water outputs to wet the mop 6 and perform targeted floor cleaning.

[0043] Further, if Figure 2 and Figure 3 As shown, a water tank 8 is rotatably provided on the bottom plate 2, the water tank 8 is connected to the pressurizing structure, a water outlet 811 is provided in the water tank 8, a movable blocking structure is provided on the water outlet 811, the identification structure identifies the degree of dirt on the ground, and controls the cleaning device to adopt different cleaning modes, and the driving structure drives the water tank 8 to rotate so that the blocking structure moves in the water tank 8, and the blocking structure blocks the water outlets 811 of different areas, thereby achieving different water outputs from the water outlet 811.

[0044] Furthermore, a driving structure is provided on the base plate 2, and the driving structure is connected to the pressurizing structure. The driving structure drives the pressurizing structure to rotate, so that the pressurizing structure drives the water tank 8 to rotate. The water inside the water tank 8 accumulates to one end of the water tank 8 under the action of gravity, so that the blocking structure moves to open the water outlet 811, thereby realizing that the water inside the water tank 8 flows into the water outlet 811.

[0045] Specifically, the drive structure includes a second motor 13 connected to a second gear 14. The second motor 13 rotates forward or reverse to drive the second gear 14. The second gear 14 meshes with the first gear 12, which is connected to the screw 11. Rotation of the second gear 14 drives both the first gear 12 and the screw 11. A nut 10 is screwed onto the screw 11. The forward or reverse rotation of the second gear 14 moves the nut 10 on the screw 11 toward or away from the first gear 12.

[0046] According to the above embodiment, the second motor 13 drives the second gear 14 to rotate, the second gear 14 and the first gear 12 are engaged with each other, and the first gear 12 drives the screw 11 to rotate, and further drives the nut 10 to move on the screw 11, so that the nut 10 drives the movement of the first pressure rod 9, and then drives the rotation of the water tank 8.

[0047] Furthermore, the pressurizing structure includes a first pressure rod 9, which is connected to a first connecting rod 91. The first connecting rod 91 is fixedly connected to a nut 10, so that the nut 10 moves on the screw 11, thereby driving the first pressure rod 9 to move toward or away from the base plate 2. The first pressure rod 9 is connected to a second connecting rod 92, which is fixedly connected to the water tank 8, so that the first pressure rod 9 drives the water tank 8 to move. First motors 94 are provided on opposite sides of the first pressure rod 9. The first motor 94 is elastically connected to the first pressure rod 9. A second pressure rod 15 is provided at the bottom of the first motor 94, and the second pressure rod 15 is elastically connected to the base plate 2. The first motor 94 is connected to a mop 6, which is arranged below the base plate 2.

[0048] Of course, it is understandable that the embodiment provided by the present invention can also be configured as a rotary pressurization and hyperbolic connecting rod pressurization structure to realize the rotation of the water tank 8.

[0049] Further, if Figure 4 As shown, the blocking structure includes a box body 82, which is elastically connected to the inner wall of the water tank 8. The rotation of the water tank 8 drives the movement of the box body 82, thereby achieving relative movement between the box body 82 and the water outlet 811, and changing the water outlet area of the water outlet 811. The box body 82 is provided with at least two steps, at least two steps connected in sequence. The box body 82 is provided with a heavy ball 83. According to the degree of dirt on the ground, the heavy ball 83 is controlled to be placed on different steps, so that the box body 82 can cover different areas of the water outlet 811.

[0050] As a preferred embodiment, the steps include three, the heavy ball 83 is set on the first step, and the box body 82 completely covers the water outlet 811, so that the cleaning device can realize the automatic lifting mode; the heavy ball 83 is set on the second step, and the box body 82 will cover 1 / 2 of the water outlet 811, so that the cleaning device can realize the normal mopping mode; the heavy ball 83 is set on the third step, and the box body 82 will open the water outlet 811, so that the cleaning device can realize the pressurized mopping mode.

[0051] Of course, it is understandable that the number of steps can also include four, five, or more, and the water outlet 811 and the water output are set accordingly according to the number of steps.

[0052] Specifically, a chute box 81 is provided at the bottom of the water tank 8. The chute box 81 has a water outlet 811. The water outlet 811 is connected to the bottom of the water tank 8 so that the water outlet 811 and the mop 6 are positioned correspondingly. The water flowing out of the water outlet 811 wets the mop 6. A box body 82 is provided on the chute box 81, and the box body 82 moves on the chute box 81.

[0053] Furthermore, a slide rail is provided on the chute box 81 , and a slider is provided on the box body 82 . The slider moves on the slide rail, thereby enabling the box body 82 to move in the chute box 81 .

[0054] Specifically, the steps within the box body 82 are formed by alternating first inclined surfaces 821 and flat surfaces. The bottom surface of the box body 82 is provided with a first flat surface, which is connected to the first inclined surface 821, which is connected to the second flat surface, and which is connected to the second inclined surface 822. Thus, a first step, a second step, and a third step are sequentially formed, and the heavy ball 83 moves on the first, second, and third steps. When the cleaning device is in the normal mopping state, the water outlet 811 is halfway open, with an area of π / 2 square centimeters.

[0055] Furthermore, a bracket 85 is provided on the bottom plate 2 , and the side wall of the water tank 8 and the bracket 85 are hinged so that the driving structure drives the water tank 8 to rotate relatively on the bracket 85 .

[0056] The present invention also provides a cleaning robot comprising the cleaning device described above.

[0057] The cleaning robot provided by the present invention mainly realizes different mopping modes for floors with different degrees of dirtiness, and mainly supports three modes: automatic lifting mode, normal mopping mode, and pressurized mopping mode. In different modes, the robot mainly realizes three functions: pressurizing the mop 6, adjusting the water output, and redistributing the gravity of the shell. First, the cleaning robot collects ground images based on the onboard AI camera 4 to identify the degree of dirtiness of the floor; if the floor is clean and does not need to be cleaned, the robot will start the automatic lifting mode; if the floor is of general dirtiness, the robot will start the normal mopping mode for cleaning; if the floor reaches a serious degree of dirtiness, the robot will start the pressurized mopping mode for cleaning; the specific operations under different modes are as follows:

[0058] Normal mopping mode: When the AI camera 4 recognizes that the current floor is generally dirty, it will start the normal mopping mode. Figure 7 and Figure 8 As shown, the second motor 13 is driven to rotate forward, driving the second gear 14 to rotate and the screw 11 to reverse; the reversal of the screw 11 will cause the nut 10 to drop, and the nut 10 is connected to the first pressure rod 9, driving the first pressure rod 9 to drop together; the descent of the first pressure rod 9 will simultaneously drive the water tank 8 to rotate forward and the second spring 93 to drop and compress; the descent and compression process of the second spring 93 will drive the left and right first motors 94 to drop, and the descent of the first motor 94 drives the mop 6 to drop until it touches the ground. Due to the pressure of the second spring 93, there is a certain pressure between the mop 6 and the ground at this time, and the descent of the first motor 94 will drive the second pressure rod 15 to drop at the same time, and the second pressure rod 15 will compress the lifting spring pressure The water tank 8 is rotated, and the mop 6 descending program is completed; when the water tank 8 rotates forward, it will tilt, and the tilt angle can reach 15 degrees. Due to the action of gravity, the ball in the chute box 81 of the water tank 8 will roll to the first step, driving the chute box 81 to slide toward the front of the water tank 8 and compressing the spring. When the box body 82 slides, the water outlet 811 at the bottom of the water tank 8 becomes larger, and the water output is adjusted. In addition, due to the action of gravity, after the water tank 8 rotates, the water in the water tank 8 will gather more at the front of the water tank 8, which makes the center of gravity of the robot move forward, preventing the trolley mop 6 from losing balance due to excessive pressure. This design allows the system to provide greater mopping pressure. Finally, the state of the robot in normal mopping mode is as follows Figure 7 and Figure 8 shown.

[0059] Pressurized mopping mode: When the AI camera 4 recognizes that the current floor is seriously dirty, the pressurized mopping mode will be activated. Pressurized mopping mainly increases the water output and the pressure between the mop 6 and the floor. Figure 9 and Figure 10, the second motor 13 continues to rotate forward, driving the first gear 12 to rotate, the nut 10 continues to reverse, and the nut 10 and the first pressure rod 9 continue to descend together; at this time, the water tank 8 continues to rotate forward and tilts more seriously, and the left (right) second spring 93 will continue to contract and pressurize. This pressure will be transmitted to the mop 6 through the first motor 94, thereby increasing the pressure between the mop 6 and the ground; when the water tank 8 tilts more seriously, the maximum tilt angle can reach 30 degrees. Due to the action of gravity, the heavy ball 83 will roll to the second step, continuing to drive the box body 82 to slide toward the front of the water tank 8 and further compressing the first spring 84. When the box body 82 slides, the water outlet 811 at the bottom of the water tank 8 becomes the largest, achieving maximum water output; at this time, the water tank 8 is aggravated by the degree of tilt, and there will be more water in the front of the water tank 8. The center of gravity of the trolley continues to move forward, thereby ensuring the balance of the trolley and achieving maximum pressurization pressure. Finally, the state of the robot in the pressurized mopping mode is as follows Figure 9 and Figure 10 shown.

[0060] Automatic lift mode: When the AI camera 4 recognizes that the current floor is clean and does not need to be cleaned, it will start the automatic lift mode to achieve energy saving. Figure 5 and Figure 6 In the process, the second motor 13 rotates in the reverse direction, driving the second gear 14 to rotate, and the nut 10 rotates forward, driving the nut 10 and the first pressure rod 9 to rise together; after the first pressure rod 9 rises, the water tank 8 will return to the horizontal position and the second spring 93 will also recover. At this time, the third spring 151 will recover, driving the second pressure rod 15 to rise. The rising of the second pressure rod 15 will drive the first motor 94 to rise and the mop 6 to rise, thereby realizing the automatic lifting of the mop 6; Figure 6 As shown, when the water tank 8 returns to the horizontal position, the box body 82 will also be in the horizontal position. Due to the action of gravity, the heavy ball 83 will roll to the horizontal track, and the first spring 84 will resume its extension, thereby pushing the box body 82 to move to the rear of the water tank 8 until it reaches the limit position of the guide rail. After the box body 82 reaches the limit position, the water outlet 811 is blocked and no water will flow out. Finally, the state of the robot in the automatic lifting mode is as follows Figure 5 and Figure 6 shown.

[0061] The present invention provides a cleaning device and cleaning robot. The rotation of a nut 10 drives a pressure plate downward, compressing a second spring 93 to achieve multi-level pressure on a mop 6. Different mopping modes are adopted for different levels of floor dirtiness, making the cleaning robot more intelligent. During pressurized mopping, the pressure in the water tank 8 is simultaneously redistributed, adjusting the center of gravity of the cleaning robot to achieve greater pressure mopping, resulting in higher efficiency and lower costs.

[0062] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
