Description

Technical Field

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

[0002] When cleaning floor surfaces, household floor scrubbers are prone to leaving water and dirt stains on the floor surface. This is especially true when the user pulls the scrubber backwards, where the residual water and dirt in front of the roller brush becomes more severe, affecting the scrubber's cleaning performance. To prevent residual water and dirt stains on the floor surface, some floor scrubbers are equipped with a scraper bar in front of the roller brush. For example, Chinese utility model patent CN221430984U provides a front-mounted mechanical scraper bar structure. This structure, through the provision of a drive structure, drives the scraper bar toward the surface to be cleaned and into contact with the surface. As the scrubber is pulled backwards, the scraper bar can scrape off dirt on the surface, thereby helping to reduce residual water and dirt stains on the surface. However, this front mechanical scraper is also very likely to retain dirt during the process of reciprocating lifting and frequently contacting and rubbing the ground for cleaning. Since the front scraper is far away from the suction structure of the floor scrubber, the dirt remaining on the scraper cannot be sucked away in time, thereby affecting the subsequent scraping effect of the ground dirt. Moreover, if the dirt on the scraper dries and sticks, it will become difficult to clean the scraper itself.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0004] The purpose of the utility model is to provide a cleaning device which can solve the problem that the dirt remaining on the surface of the existing front mechanical scraper is difficult to clean.

[0005] The utility model provides a cleaning device, including a floor brush and a vibration mechanism.

[0006] Wherein, the floor brush comprises:

[0007] The floor brush body is capable of moving along a preset direction of travel on the surface to be cleaned;

[0008] A cleaning member rotatably provided on the floor brush body, the cleaning member being used to clean the surface to be cleaned;

[0009] A scraper bar assembly includes a scraper bar and a drive mechanism, wherein the scraper bar is provided at the front side of the cleaning member in the preset direction of travel and has a retracted state and a lowered state. When the scraper bar moves in a direction opposite to the preset direction of travel, the scraper bar is in the lowered state to contact the surface to be cleaned. The drive mechanism is in transmission connection with the scraper bar assembly and is used to drive the scraper bar to rise or fall so as to switch the scraper bar to the retracted state or the lowered state.

[0010] The vibration mechanism is used to provide vibration to clean the dirt attached to the scraper strip.

[0011] At present, there is no special scrubbing mechanism to automatically scrub the dirt attached to the scraper bar, and manual cleaning is required, which affects the user experience. If a special scrubbing mechanism is set up for the scraper bar, the overall spatial layout of the cleaning equipment will need to be redesigned due to factors such as the large scrubbing action stroke of the scrubbing mechanism, the complex mechanical transmission structure and the large size, and the existing model cannot be simply modified. In this application, the scraper bar is not cleaned by the traditional contact scrubbing method, but the dirt on the scraper bar is directly or indirectly removed by vibration. For example, the scraper bar is directly vibrated and the attached dirt is thrown out by its own shaking. The self-shaking in the liquid can enhance its self-cleaning effect. For example, the scraper bar can be indirectly vibrated by vibrating the cleaning liquid, so that friction occurs between the cleaning liquid and the scraper bar for cleaning. The vibration cleaning method can reduce the wear of the scraper bar, and only a small vibration mechanism needs to be added, which can easily modify the existing model.

[0012] Further optionally, the cleaning device further includes:

[0013] A base station for placing the floor brush, wherein the cleaning device has a self-cleaning mode, which can be activated when the floor brush is placed on the base station;

[0014] The base station comprises a cleaning tank for storing cleaning liquid. The scraper bar and the cleaning member partially or completely fall into the cleaning liquid in the cleaning tank in the self-cleaning mode.

[0015] In this embodiment, by utilizing the cleaning tank of the base station to cooperate with the vibration cleaning of the scraper, the scraper is more easily self-cleaned under the action of vibration when immersed in the cleaning liquid, and the vibration cleaning operation of the scraper is synchronized with the original self-cleaning mode of the cleaning equipment to improve the overall cleaning efficiency.

[0016] In an optional embodiment, the vibration mechanism includes a first vibration module, which is disposed at the base station and has a vibration output terminal located within the cleaning tank to apply vibration to the cleaning liquid. In this embodiment, the vibration of the cleaning liquid indirectly vibrates the scraper, causing friction between the cleaning liquid and the scraper to achieve deep cleaning.

[0017] Further optionally, the first vibration module is configured to output ultrasonic vibrations to the cleaning liquid to ultrasonically clean the scraper, the distance between the vibration output end of the first vibration module and the cleaning member is greater than a first preset distance, and the distance between the vibration output end of the first vibration module and the scraper is greater than a second preset distance. In this embodiment, the vibration output end of the first vibration module does not directly contact the cleaning member and the scraper to reduce unnecessary energy loss of the first vibration module. The vibration output of the first vibration module is entirely applied to the cleaning liquid to achieve ultrasonic cleaning of the scraper by the cleaning liquid.

[0018] Further optionally, the vibration mechanism includes a first vibration module, which is disposed in the base station, has a vibration output end located in the cleaning tank, and contacts the scraper to transmit vibration in the self-cleaning mode. In this embodiment, the first vibration module directly outputs vibration to the scraper through contact, and also indirectly outputs vibration to the scraper via the cleaning liquid in the cleaning tank, thereby creating a dual vibration effect for the scraper, thereby improving cleaning efficiency.

[0019] Further optionally, the vibration mechanism includes a second vibration module, which is arranged on the floor brush; the vibration output end of the second vibration module acts on the scraper, causing the scraper to vibrate; and the second vibration module is enabled in the self-cleaning mode.

[0020] Further optionally, the cleaning tank includes a first cleaning tank and a second cleaning tank. In the self-cleaning mode, part or all of the scraper falls into the cleaning liquid of the first cleaning tank, and part or all of the cleaning member falls into the cleaning liquid of the second cleaning tank.

[0021] Further optionally, the first cleaning tank and the second cleaning tank are independent of each other, and the vibration output end of the first vibration module is located in the first cleaning tank.

[0022] Further optionally, a channel for the cleaning liquid to flow is provided between the first cleaning tank and the second cleaning tank, and the vibration output end of the first vibration module is located in the first cleaning tank or the second cleaning tank.

[0023] Further optionally, the first cleaning tank has a first tank bottom, the lowest point of the first tank bottom is provided with a first drainage port, and the first drainage port is connected to the second cleaning tank; the second cleaning tank has a second tank bottom, and the lowest point of the first tank bottom is not lower than the lowest point of the second tank bottom.

[0024] Further optionally, the scraper bar is in a lowered state in the self-cleaning mode so as to place the scraper bar in the cleaning liquid as much as possible to improve the cleaning effect.

[0025] Optionally, the vibration mechanism includes a second vibration module, which is mounted on the floor brush; the vibration output of the second vibration module acts on the scraping bar, causing the scraping bar to vibrate. In this embodiment, the second vibration module actively vibrates the scraping bar, thereby promptly shaking off attached liquid dirt to prevent it from drying and scaling.

[0026] Further optionally, the vibration frequency output by the second vibration module is lower than 50 Hz.

[0027] Further optionally, the second vibration module is configured to be activated when the wiper strip is in a retracted state.

[0028] Further optionally, the cleaning device has a vibration mopping mode. In the vibration mopping mode, the scraper bar switches to a lowered state to contact the surface to be cleaned, and the second vibration module outputs vibration to the scraper bar, causing the scraper bar to rub against the surface to be cleaned. This embodiment is suitable for cleaning stubborn stains, including two situations. In the first situation, the dirt on the scraper bar is difficult to remove by shaking or soaking; in the second situation, the dirt on the surface to be cleaned cannot be cleaned off by conventional floor brushes. In this case, the vibration mopping mode is activated, and vibration friction is generated between the scraper bar and the surface to be cleaned to wipe away stubborn stains on the scraper bar or the surface to be cleaned, thereby improving the cleaning ability of stubborn stains.

[0029] Further optionally, the scraping bar is rotatably connected to the floor brush body, the driving mechanism is configured to drive the scraping bar to rotate toward the cleaning member and abut against it, and the cleaning member is configured to clean the abutted scraping bar by rotating. In this embodiment, the scraping bar is driven to abut against the cleaning member so that the cleaning member can roll and clean the scraping bar.

[0030] Further optionally, a light sensor is provided on the scraper bar assembly for detecting whether the scraper bar is covered with dirt.

[0031] The utility model also provides a cleaning device, including a floor brush, a vibration mechanism and a base station.

[0032] Wherein, the floor brush comprises:

[0033] The floor brush body is capable of moving along a preset direction of travel on the surface to be cleaned;

[0034] A cleaning member rotatably provided on the floor brush body, the cleaning member being used to clean the surface to be cleaned;

[0035] The scraper bar assembly comprises a scraper bar and a driving mechanism, wherein the scraper bar is arranged at the front side of the cleaning member in the preset direction of travel and has a retracted state and a lowered state. When the scraper bar moves in the preset direction of travel, it is in the retracted state to maintain a distance from the surface to be cleaned. When the scraper bar moves in the direction opposite to the preset direction of travel, it is in the lowered state to contact the surface to be cleaned. The driving mechanism is transmission-connected to the scraper bar assembly, and the driving mechanism is used to drive the scraper bar to rise or fall so as to switch the scraper bar to the retracted state or the lowered state.

[0036] The base station is used to place the floor brush; the base station includes a cleaning tank, the cleaning tank is used to store cleaning liquid, and the scraper and the cleaning member are partially or completely dropped into the cleaning liquid in the cleaning tank when the floor brush is placed on the base station;

[0037] The vibration mechanism includes a first vibration module, which is arranged at the base station, and a vibration output end of the first vibration module is located in the cleaning tank to apply vibration to the cleaning liquid to perform ultrasonic cleaning on the scraper.

[0044] Wherein, the vibration mechanism includes a second vibration module, and the second vibration module is arranged on the floor brush; the vibration output end of the second vibration module acts on the scraping strip, so that the scraping strip vibrates.

[0045] Compared with the prior art, the cleaning device according to the present invention is provided with a vibration mechanism for vibrating and cleaning the front mechanical scraper.

[0046] According to the cleaning equipment of the present invention, the vibration mechanism includes a first vibration module, which is arranged at the base station, and the vibration output end of the first vibration module is located in the cleaning tank to apply vibration to the cleaning liquid, thereby cleaning the scraper contained in the cleaning tank. Through this vibration cleaning method, when the floor brush is placed on the base station after washing the floor, the self-cleaning mode is started to clean the scraper, ensuring that the scraper is in a clean state when it works next time, avoiding dirt residue, and improving the cleaning effect of the cleaning equipment.

[0047] According to the cleaning equipment of the present invention, the vibration mechanism includes a second vibration module, which is arranged on the floor brush.

[0058] To make the technical solutions and beneficial effects of the present invention more clearly understood, the following detailed description is given by way of specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly illustrate the details of the local features. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0059] In the description of the present invention, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of simplifying the description of the present invention, and do not indicate that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and should not be understood as a limitation to the present invention.

[0060] In this utility model, the terms "first" and "second" are used solely for descriptive purposes and should not be construed as indicating the relative importance of the features indicated or the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two or three, and "several" means at least one, such as one, two, or three, unless otherwise expressly specified.

[0061] In this utility model, unless otherwise expressly defined, the terms "install," "connect," "connect," "fix," "dispose," etc. should be understood broadly. For example, "connect" can mean fixed, removable, or integrated; it can mean mechanical or electrical; it can mean direct or indirect connection through an intermediary; it can also mean internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0062] In the present invention, unless otherwise clearly defined, when a first feature is “on,” “above,” “above,” “above,” “below,” “below,” or “below” a second feature, the first feature and the second feature may be in direct contact, or the first feature and the second feature may be in indirect contact via an intermediate medium.

When a first feature is “below,” “below,” or “below” a second feature, it may mean that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than the horizontal height of the second feature.

[0063] As described in the background technology, in the prior art, the front mechanical scraper is very likely to retain dirt during the process of reciprocating lifting and frequently contacting and rubbing the ground for cleaning. Since the front scraper is far away from the suction structure of the floor scrubber, the dirt remaining on the scraper cannot be sucked away in time, thereby affecting the subsequent scraping effect of the dirt on the ground. Moreover, if the dirt on the scraper dries and sticks, it will become difficult to clean the scraper itself.

[0064] At present, there is no special scrubbing mechanism to automatically scrub the dirt attached to the scraper, and it needs to be manually cleaned, which affects the user experience. If a special scrubbing mechanism is set up for the scraper, the overall spatial layout of the cleaning equipment needs to be redesigned due to factors such as the large scrubbing action stroke of the scrubbing mechanism, the complex mechanical transmission structure and the large size, and the existing model cannot be simply modified.

[0065] In order to solve the above technical problems, the utility model provides a cleaning device, which is equipped with a vibration mechanism for vibrating and cleaning the front mechanical scraper. By applying the vibration provided by the vibration mechanism to the scraper, the dirt attached to the scraper is cleaned, thereby solving the problem that the residual dirt on the surface of the existing front mechanical scraper is difficult to clean.

[0066] In the following embodiments, a substantially flat ground is used as a reference object for the surface 3 to be cleaned, wherein the preset moving direction X is substantially parallel to the surface 3 to be cleaned, that is, the direction in which the floor brush moves substantially horizontally, and the height direction Y is substantially perpendicular to the surface 3 to be cleaned.

[0067] Example 1

[0068] like Figure 1-Figure 4 As shown, this embodiment provides a cleaning device, which can be a floor scrubber. The cleaning device includes a floor brush 1, which includes a floor brush body 11, a cleaning member 12, a scraper assembly 13, and a lifting drive assembly. It should be noted that, Figure 1-Figure 4 Only a part of the structure of the floor brush is shown as an example, and the remaining structures such as the gripping part, water tank, etc. are not shown.

[0069] The floor brush body 11 is capable of moving along a predetermined direction of travel, i.e., the X-direction, on the surface to be cleaned 3, which may be a floor, for example. A cleaning member 12 is rotatably mounted on the floor brush body 11 and is used to clean the surface to be cleaned 3. In this embodiment, the cleaning member 12 may be a roller brush rotatably mounted on the front side of the floor brush body 11. In other alternative embodiments, the cleaning member 12 may also be a brush disc, a bristle brush, etc., and the mounting position of the cleaning member 12 may be adjusted according to specific needs.

[0070] The scraper bar assembly 13 is arranged on the front side of the cleaning member 12 in the preset travel direction X, wherein the scraper bar assembly 13 includes a scraper bar 131 and a driving mechanism, the scraper bar 131 is used to scrape off dirt on the surface to be cleaned 3; the driving mechanism is transmission-connected to the scraper bar assembly 13, and is used to drive the scraper bar 131 to rise or fall, so that the scraper bar 131 has a retracted state or a lowered state.

[0071] The drive mechanism (not shown) is disposed within the floor brush body 11. The retracted state refers to the state in which the scraping bar 131 is away from the surface 3 to be cleaned, and the lowered state refers to the state in which the scraping bar 131 is in contact with the surface 3 to be cleaned. When the scraping bar 131 moves in a predetermined direction of travel X, it is in the retracted state to maintain a distance from the surface 3 to be cleaned. When it moves in a direction opposite to the predetermined direction of travel X, it is in the lowered state to contact the surface 3 to be cleaned. The scraping bar 131 is driven up by the transmission of the driving mechanism, so that the scraping bar 131 is retracted. When the floor brush body 11 cleans the surface 3 to be cleaned along the preset travel direction X, the scraping bar 131 is in a retracted state to prevent the scraping bar 131 from rubbing against the surface 3 to be cleaned and hindering the cleaning work of the cleaning member 12; the scraping bar 131 is driven down by the transmission of the driving mechanism, so that the scraping bar 131 is lowered. When the floor brush body 11 is pulled back, the scraping bar 131 is in a lowered state, and the scraping bar 131 is in contact with the ground, so that the scraping bar 131 scrapes off the dirt on the ground during the process of pulling the floor brush body 11 back, avoiding residual water stains or stains on the ground.

[0072] It is understandable that the situation of pulling back the floor brush body may occur in a variety of scenarios. For example, when encountering obstacles such as blind spots, corners, furniture, etc., the floor brush body 11 needs to be pulled back. In this case, the front scraper 131 is lowered, which can help to scrape the blind spots that the cleaning part 12 cannot clean. When encountering stubborn stains that are difficult to clean, it is necessary to push and pull the floor brush repeatedly to enhance the cleaning effect. In this case, the scraper 131 is lowered to scrape the stubborn stains and also assist the cleaning part to improve the cleaning efficiency.

[0073] It should be noted that the rising and falling movement of the front mechanical scraper in the present application is not limited to a straight rise or fall along the height direction Y, but can also be a rotation or swinging movement at a certain angle relative to the height direction Y during the rising or falling process. The movement trajectory of the scraper 131 can be set according to actual use needs, as long as it is ensured that the scraper 131 can finally separate from or abut against the surface 3 to be cleaned.

[0074] It should be noted that the driving mechanism for driving the scraper 131 to rise and fall does not involve the core concept of this application. It can adopt the driving structure such as motor drive, hydraulic drive in the existing technology, or it can be set according to specific needs. Transmission structure such as screw rod and connecting rod will not be repeated here.

[0075] During the process of the scraper bar 131 moving back and forth and frequently contacting and rubbing the ground for cleaning, it is very easy for dirt to remain on it. Since the scraper bar 131 is arranged on the front side of the cleaning member 12, it is far away from the suction structure of the floor brush 1 (the suction structure is usually arranged on the rear side of the cleaning member 12, located in the middle of the floor brush 1). Therefore, the dirt remaining on the scraper bar cannot be sucked away in time. If it cannot be cleaned in time, a large amount of dirt will remain on the scraper bar, which will instead contaminate the ground and affect the cleaning effect. Moreover, if the dirt on the scraper bar dries and sticks, it will become difficult to clean the scraper bar itself.

[0076] To this end, the cleaning device of the present application also includes a vibration mechanism for providing vibration to clean the dirt attached to the scraper. By providing the vibration mechanism, not only can the dirt attached to the scraper be cleaned in a timely manner, but it can also ensure that the scraper can subsequently effectively scrape off the floor stains, thereby improving the cleaning effect.

[0077] In addition, the cleaning device also includes a base station 2, which is used to cooperate with the floor brush 1 to place the floor brush 1. It can be understood that when using the base station 2 compatible with the floor brush 1, after the floor brush 1 is used, the floor brush 1 is returned to the base station 2, and the base station 2 can provide the floor brush 1 with functions such as liquid supply, liquid drainage, self-cleaning, drying and charging. Among them, the cleaning device has a self-cleaning mode, which can be activated when the floor brush 1 is placed on the base station 1. In this mode, the floor brush 1 can clean itself, especially the parts that are easily contaminated with dirt, such as the scraper 131 and the cleaning member 12. Specifically, the base station includes a cleaning tank, which is used to store cleaning liquid. The cleaning liquid can be, for example, water; in the self-cleaning mode, the scraper 131 and the cleaning member 12 both partially or completely fall into the cleaning liquid in the cleaning tank for cleaning.

[0078] By utilizing the cleaning tank of the base station to cooperate with the vibration cleaning of the scraper, the scraper is more likely to self-clean under the action of vibration when immersed in the cleaning liquid, and the vibration cleaning operation of the scraper is synchronized with the original self-cleaning mode of the cleaning equipment to improve the overall cleaning efficiency.

[0079] Example 2

[0080] On the basis of the first embodiment, this embodiment provides a cleaning device, such as Figure 3 As shown, the vibration mechanism includes a first vibration module 21, which is arranged at the base station 2, and a vibration output end thereof is located in the cleaning tank, so as to clean the scraper 131 falling into the cleaning liquid in the cleaning tank.

[0081] In some embodiments, the vibration output end of the first vibration module 21 is located within the cleaning tank to apply vibration to the cleaning liquid. Specifically, the first vibration module 21 is configured to provide high-frequency vibration, such as ultrasonic vibration. The first vibration module 21 is configured to output ultrasonic vibration to the cleaning liquid to ultrasonically clean the scraper 131. The distance between the vibration output end of the first vibration module 21 and the cleaning member 12 is greater than a first predetermined distance, and the distance between the vibration output end of the first vibration module 21 and the scraper 131 is greater than a second predetermined distance. In other words, the vibration output end of the first vibration module 21 does not contact either the scraper 131 or the cleaning member 12. The vibration output of the first vibration module 21 acts on the cleaning liquid. The high-frequency vibration of the first vibration module 21 creates vacuum bubbles in the cleaning liquid, which are then separated from the scraper 131 by the bursting of the vacuum bubbles, achieving rapid and effective cleaning. The vibration output end of the first vibration module does not directly contact the cleaning member or the scraper, thereby reducing unnecessary energy loss in the first vibration module. The vibration output of the first vibration module acts entirely on the cleaning liquid to achieve ultrasonic cleaning of the scraper by the cleaning liquid. Optionally, the frequency of the high-frequency vibration provided by the first vibration module 21 is 20-30 kHz.

[0082] In some alternative embodiments, the vibration output end of the first vibration module 21 contacts the scraper 131 in the self-cleaning mode to transmit vibration. That is, the vibration output end of the first vibration module 21 is in direct contact with the scraper 131, and the vibration is directly applied to the scraper 131, so that the scraper cleans the dirt in the cleaning liquid under its own vibration. At the same time, the scraper can also be indirectly vibrated by the cleaning liquid in the cleaning tank, forming a double vibration effect of the scraper to improve the cleaning efficiency.

[0083] In some alternative embodiments, such as Figure 4 As shown, the vibration mechanism includes a second vibration module 14, which is installed on the floor brush. The vibration output end of the second vibration module 14 acts on the scraping bar 131, causing the scraping bar 131 to vibrate. The second vibration module 14 is activated in the self-cleaning mode. By installing the second vibration module 14 on the floor brush and the vibration output end of the second vibration module 14 acting on the scraping bar 131, the vibration can be directly transmitted to the scraping bar 131, so that the scraping bar removes dirt in the cleaning liquid under its own vibration.

[0084] It can be understood that, in order to supply cleaning liquid to the cleaning tank, the base station 2 further includes a cleaning liquid supply part; in order to discharge the used cleaning liquid, the base station 2 further includes a cleaning liquid discharge part.

[0085] Optionally, the cleaning tank includes a first cleaning tank 22 and a second cleaning tank 23 . In the self-cleaning mode, part or all of the scraper bar 131 falls into the cleaning liquid of the first cleaning tank 22 , and part or all of the cleaning member 12 falls into the cleaning liquid of the second cleaning tank 23 .

[0086] In some embodiments, the first cleaning tank 22 and the second cleaning tank 23 can be the same cleaning tank, and the scraper bar 131 and the cleaning member 12 are placed together in the cleaning tank for cleaning. This arrangement simplifies the structural configuration of the cleaning tank. In addition, when the first vibration module 21 applies ultrasonic vibration to the cleaning liquid, it can simultaneously clean the scraper bar 131 and the cleaning member 12 with high-frequency vibration, thereby improving the cleaning effect of the cleaning member 12.

[0087] In some alternative embodiments, the first cleaning tank 22 and the second cleaning tank 23 may be different and independent cleaning tanks, and the scraper 131 and the cleaning member 12 are cleaned in the first cleaning tank 22 and the second cleaning tank 23 respectively without affecting each other, wherein, in order to vibrate and clean the scraper, the vibration output end of the first vibration module 21 is located in the first cleaning tank 22.

[0088] It is understood that the cleaning of the cleaning member 12 in the cleaning tank can be achieved by rotating the cleaning member 12 itself, etc. Compared to the method of setting up the same cleaning tank, in the method of independently setting up the first cleaning tank 22 and the second cleaning tank 23, the vibration output end of the first vibration module 21 is located in the first cleaning tank 22, which can concentrate the vibration energy of the first vibration module 21 in the first cleaning tank 22. The vibration cleaning is only performed on the scraper 131, thereby using a smaller vibration power and saving power. Of course, in other alternative embodiments, another vibrator can also be set in the second cleaning tank 23 to implement vibration cleaning for the cleaning member 12.

[0089] In some alternative embodiments, a channel for the circulation of cleaning liquid is provided between the first cleaning tank 22 and the second cleaning tank 23, and the vibration output end of the first vibration module 21 is located in the first cleaning tank 22 or the second cleaning tank 23. In order to facilitate the filling and discharge of cleaning liquid in the first cleaning tank 22, the first cleaning tank 22 and the second cleaning tank 23 are arranged to be connected. In this way, cleaning liquid can be filled into the first cleaning tank 22 from the cleaning liquid supply part through the second cleaning tank 23, and the used cleaning liquid in the first cleaning tank 22 can be discharged to the cleaning liquid discharge part through the second cleaning tank 23. There is no need to set up additional cleaning liquid supply and discharge channels for the first cleaning tank 22, which simplifies the overall structure of the brush and facilitates the synchronous cleaning of the scraper 131 and the cleaning member 12 in the self-cleaning mode.

[0090] Optionally, the first cleaning tank 22 has a first bottom, which can be tilted, and a first drain port is provided at the lowest point of the first bottom, which is connected to the second cleaning tank 23. The second cleaning tank 23 has a second bottom, which can be tilted, and a second drain port is provided at the lowest point of the second bottom, with the lowest point of the first bottom not lower than the lowest point of the second bottom. This arrangement facilitates the collection and discharge of cleaning liquid. The first cleaning tank 22 and the second cleaning tank 23 are connected through the first drain port. Along the height direction Y, the overall depth of the first cleaning tank 22 is slightly shallower than that of the second cleaning tank 23. This ensures that the cleaning liquid in the first cleaning tank 22 can be completely discharged through the second cleaning tank 23, and the cleaning liquid in the second cleaning tank 23 can also be completely discharged to the cleaning liquid discharge portion through the second drain port, ensuring that no dirty cleaning liquid remains. In some embodiments, the first cleaning tank 22 and the second cleaning tank 23 can be separated by a partition, and a first drain port is provided at the bottom of the partition corresponding to the lowest point of the bottom of the first tank, so that the first cleaning tank 22 and the second cleaning tank 23 are directly connected through the first drain port; in some alternative embodiments, the first cleaning tank 22 and the second cleaning tank 23 can be set at a certain distance from each other, and the first cleaning tank 22 and the second cleaning tank 23 can be connected through the first drain port to connect the cleaning liquid channel to achieve communication.

[0091] Optionally, at least one first vibration module 21 is provided. In some embodiments, one first vibration module 21 is provided. To avoid vibration energy loss, the first vibration module 21 can be positioned adjacent to the first cleaning tank 22. Preferably, the first vibration module 21 can be positioned in the middle of the wall or bottom of the first cleaning tank 22. In other embodiments, two or more first vibration modules 21 are provided, and the two or more first vibration modules 21 can be evenly arranged along the wall or bottom of the first cleaning tank 22 to provide more uniform vibration. In actual use, the number of first vibration modules 21 installed can be set according to specific cleaning needs.

[0092] In some embodiments, the scraper bar 131 is in a lowered position in the self-cleaning mode. It will be appreciated that in this lowered position, the scraper bar 131 can more easily be dropped into the cleaning liquid for cleaning, thereby minimizing the amount of time the scraper bar is placed within the cleaning liquid to improve cleaning effectiveness. In alternative embodiments, the scraper bar 131 can also be dropped into the cleaning liquid for cleaning by switching between a lowered and retracted position. The upward and downward movement of the scraper bar can be used to agitate the cleaning liquid to improve cleaning effectiveness.

[0093] Optionally, a light sensor is provided on the scraper bar 131 to detect whether the scraper bar 131 is covered with dirt. It is understandable that when there is no dirt on the scraper bar, the light sensor on the scraper bar is completely unobstructed and the received light intensity is the strongest, thereby judging that the scraper bar is in a clean state and can be used for floor cleaning; when the light intensity received by the light sensor weakens, it indicates that it is blocked by dirt, and the control system in the floor brush will judge the degree of dirt on the scraper bar based on the degree of weakening of the light received by the light sensor, and then start cleaning the scraper bar; when the dirt on the scraper bar is cleaned, the light intensity received by the light sensor returns to the strongest again, at which point the control system controls the scraper bar to stop cleaning. Further optionally, multiple light sensors can be evenly arranged on the scraper bar to make the detection more accurate and prevent misjudgment.

[0094] Optionally, the cleaning tank further includes a dirt sensor for determining the turbidity of the cleaning liquid. When the scraper bar 131 and the cleaning member 12 perform self-cleaning in the cleaning tank of the base station 2, the dirt sensor detects the turbidity of the cleaning liquid to determine whether to stop self-cleaning.

[0095] In some embodiments, the dirtiness of the scraper strip can be directly judged manually to determine whether the scraper strip needs to be cleaned. For example, a cleaning button can be set on the cleaning device and the cleaning button can be triggered as needed to control the cleaning of the scraper strip.

[0096] In some embodiments, the scraper bar 131 is rotatably connected to the floor brush body 11, and the driving mechanism is configured to drive the scraper bar 131 to rotate toward the cleaning member 12 and abut against it. The cleaning member 12 is configured to clean the abutting scraper bar 131 by rotating. Optionally, the scraper bar assembly 13 also includes a scraper bar mounting portion 132, and the scraper bar 131 is mounted on the scraper bar mounting portion 132. The scraper bar mounting portion 132 is rotatably provided on the floor brush body 11 so that the scraper bar 131 can rotate toward the cleaning member 12 until it abuts against the cleaning member 12. For example, a rotating shaft can be provided on the scraper bar mounting portion 132, and the scraper bar mounting portion 132 can rotate around the rotating shaft under the drive of the driving mechanism. In some embodiments, the rotating shaft can also be directly provided on the scraper bar 131 as needed. The above setting provides another cleaning method for the scraper bar. In some specific scenarios, for example, when the scraper bar 131 is attached with hair that is difficult to clean by vibration, the scraper bar 131 can be swung to abut against the cleaning member 12, and the rotation of the cleaning member 12 is used to clean the scraper bar; or, when the floor brush is working and it is not possible to enter the base station 2 to perform self-cleaning on the scraper bar, the scraper bar 131 can be rotated to abut against the cleaning member 12, and the cleaning member 12 is used to clean the dirt on the scraper bar, thereby ensuring continuous operation. Further optionally, while the cleaning member 12 rotates to clean the scraper bar, the first vibration module 21 and / or the second vibration module 14 are started, and the vibration cleaning is combined with the rotation of the cleaning member 12 to clean the scraper bar, which will greatly improve the cleaning effect and efficiency of the scraper bar.

[0097] Example 3

[0098] On the basis of the first and second embodiments, this embodiment provides a cleaning device, such as Figure 4 As shown, its vibration mechanism includes a second vibration module 14, which is provided on the floor brush, and the vibration output end of the second vibration module acts on the scraper 131, causing the scraper 131 to vibrate. The active vibration of the scraper 131 is achieved by the second vibration module 14, so that the attached liquid dirt can be shaken off in time to avoid drying and scaling. On the basis of the second vibration module 14 in Example 2, the second vibration module 14 in this embodiment can act together with the first vibration module 21 in the self-cleaning mode, or can act independently of the first vibration module 21 in the self-cleaning mode, and can also be independent of the self-cleaning mode of the base station 2. The scraper 131 can be cleaned at any time as needed during the floor washing process, and the cleaning method can be flexibly selected.

[0099] Optionally, the vibration frequency output by the second vibration module 14 is lower than 50 Hz, that is, the second vibration module 14 is used to provide low-frequency vibration, thereby preventing the vibration frequency of the scraper 131 from being too high, thereby damaging the scraper or even other components in the floor brush.

[0100] In some embodiments, the vibration output end of the second vibration module 14 is connected to the scraper 131 to apply the low-frequency vibration provided by the second vibration module 14 to the scraper 131 to clean the dirt attached to the scraper; wherein, optionally, the vibration output end of the second vibration module 14 is directly connected to the scraper 131, for example, the second vibration module 14 is directly arranged on the scraper 131, and the vibration provided by it directly acts on the scraper 131; in some alternative embodiments, the vibration output end of the second vibration module 14 is indirectly connected to the scraper 131, for example, the scraper assembly 13 also includes a scraper mounting portion 132, the scraper 131 is arranged on the scraper mounting portion 132, and the second vibration module 14 is arranged on the scraper mounting portion 132, so that the vibration output end of the second vibration module 14 is connected to the scraper 131, and the vibration provided by it indirectly acts on the scraper 131 via the scraper mounting portion 132; in addition, the vibration output end of the second vibration module 14 can also be connected to other components on the floor brush to realize the transmission of vibration to the scraper 131.

[0101] In some embodiments, when the scraper bar needs to be cleaned, the second vibration module 14 is activated. The vibration provided by the second vibration module 14 is applied to the scraper bar, causing the scraper bar to vibrate, and the vibration of the scraper bar is used to shake off dirt attached to the scraper bar. Optionally, the second vibration module 14 is configured to be activated when the scraper bar 131 is in the retracted state. If the scraper bar 131 simply uses its own vibration to shake off dirt, in order to avoid damage to the scraper bar 131 due to friction with the ground, it is preferably vibrated and cleaned when the scraper bar 131 is in the retracted state.

[0102] Optionally, when the dirt attached to the scraper 131 is not easy to shake off or fall off directly, a cleaning liquid such as water can be used to assist in cleaning, and the second vibration module 14 is started. The low-frequency vibration provided by the second vibration module 14 is applied to the scraper, causing the scraper to vibrate. The scraper falls into the cleaning liquid, and the vibration of the scraper is used to clean the dirt attached to the scraper. At this time, by applying a cleaning liquid such as water to the scraper, the softening and flow of the dirt can be promoted, which helps to clean the dirt under the vibration of the scraper. Preferably, the scraper falls into the cleaning liquid in the lowered state, and the vibration of the scraper is used to clean the dirt attached to the scraper. Among them, the cleaning liquid is not limited to its state, and can be a small amount of water sprayed on the ground, or it can be accumulated water on the ground, or it can be in a pool, or it can be in the cleaning tank of the base station 2, and so on.

[0103] Optionally, the second vibration module 14 is set to at least one. In some embodiments, the second vibration module 14 is set to one. Since the scraper bar is usually in the shape of a long strip, the second vibration module 14 can be set in the middle along the length of the scraper bar. In some embodiments, the second vibration module 14 is set to more than two, and the more than two second vibration modules 14 can be evenly arranged in the length direction of the scraper bar, thereby applying more uniform vibration.

[0104] In some embodiments, the cleaning device has a vibration mopping mode. In this mode, the scraper bar 131 is switched to a lowered position to contact the surface to be cleaned 3, and the second vibration module 14 outputs vibration to the scraper bar 131, causing the scraper bar 131 to rub against the surface to be cleaned 3. This vibration mopping mode is suitable for cleaning stubborn stains, including two situations. In the first situation, the dirt on the scraper bar is difficult to remove by shaking or soaking; in the second situation, the dirt on the surface to be cleaned cannot be cleaned by conventional floor brushes. In this case, the vibration mopping mode is activated, and vibration friction is generated between the scraper bar and the surface to be cleaned to wipe away stubborn stains on the scraper bar or the surface to be cleaned, thereby improving the cleaning ability of stubborn stains. It is understood that when the scraper bar 131 is in the lowered position, the second vibration module 14 is activated, and the vibration provided by the second vibration module 14 is applied to the scraper bar 131, causing the scraper bar to vibrate, and the dirt on the surface to be cleaned 3 is cleaned by the vibration of the scraper bar. The vibration of the scraper bar 131 can not only clean its own dirt, but also mop the floor through vibration, especially when encountering obstacles such as cleaning dead corners, corners, furniture, etc., the cleaning part 12 is difficult to clean these areas, or when encountering stubborn stains such as sticky objects during the cleaning process, the scraper bar can be driven down to the lowered state, and the vibration of the scraper bar can be used to vibrate and clean these cleaning dead corners or stubborn stains, thereby improving the cleaning effect of the floor brush.

[0105] The present application utilizes vibration to directly or indirectly remove dirt from the scraper bar. For example, the scraper bar can be directly vibrated to shake off the attached dirt through its own shaking. The self-shaking in the liquid can enhance its self-cleaning effect. For example, the scraper bar can be indirectly vibrated by vibrating the cleaning liquid, so that friction occurs between the cleaning liquid and the scraper bar for cleaning. Cleaning by vibration can reduce the wear of the scraper bar. Only a small vibration mechanism needs to be added, and the existing model can be easily modified.

[0106] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present application and do not limit the scope of protection of the patent application.
