The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It is also to be understood that the terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.

Cleaning device, such as robot of sweeping floor, has gradually got into people's life, however current machine of sweeping floor is only had the function of sweeping floor more, like set up the dish brush on cleaning device, through driving the rotation of dish brush, realize cleaning ground, and this kind of cleaning device's cleaning performance is relatively poor, still need to make a round trip to clean to wait to clean the region simultaneously, consequently also comparatively consuming time. Of course, cleaning devices with sweeping and mopping functions are also available on the market, but such cleaning devices can leave stains such as liquid on the floor, resulting in undesirable cleaning effects.

In order to further improve the cleaning effect, the embodiment of the application provides a cleaning device, which is provided with a scraping strip in abutting connection with a surface to be cleaned besides sweeping and mopping, and the scraping strip is used for removing water and dust on the surface to be cleaned along with the movement of the cleaning device so as to improve the cleaning effect.

Specifically, the scraping strip of the cleaning device may be disposed at the rear of the cleaning component of the cleaning device, so as to scrape the surface to be cleaned after the cleaning component cleans the surface to be cleaned, so as to remove stains (also referred to as water stains) such as liquid or fixed stains on the surface to be cleaned, thereby improving the cleaning effect.

It should be noted that, the surface to be cleaned is an object to be cleaned by the cleaning device, specifically, for example, a floor, a glass surface, or a wall surface, and for convenience of understanding, the floor will be described as an example of the surface to be cleaned in some embodiments.

The scraping strip can remove water and dust to improve the cleaning effect, but the scraping water easily causes water dust to leak from the side of the two ends of the scraping strip, so that the cleaning effect of the cleaning device is affected. For example, as shown in fig. 1, when the cleaning device wipes a surface to be cleaned using the wiper 11, water stains may accumulate in front of the wiper 11, and as the wiping time is longer, the water stains accumulate more, and water stain side leakage is easily formed from both end portions 101 of the wiper 11. Further, due to the water stain and the tension between the both end portions 101 of the wiper strip 11, the water stain may be laterally leaked to the wiping area that has been wiped, that is, the water stain may remain on the surface to be cleaned that has been cleaned. Therefore, the cleaning device which automatically plans the path or the cleaning device which requires the user to push the travelling is generally not used for cleaning the cleaned area, so that water stains left on the cleaned surface to be cleaned can seriously affect the cleaning effect and further affect the use experience of the user.

In fig. 1, the direction of movement indicated by the arrow is the direction of movement of the wiper strip 11, and the wiper strip 11 is generally driven by the cleaning device and can therefore also be understood as the direction of movement of the cleaning device. The front side of the wiper 11 in the moving direction of the cleaning device means the side of the wiper that is not wiped, i.e. the side of the wiper 11 that is to be wiped, and may also be referred to as the front side of the wiper 11; the rear side of the wiper strip 11 in the moving direction of the cleaning device refers to the side of the wiper strip 11 that has been wiped off, and may also be referred to as the rear of the wiper strip 11. The wiping area of the wiper strip 11 is the area of the wiper strip that can be wiped on the surface to be cleaned. That is, it can be simply understood that the wiper strip 11 divides the moving area of the cleaning device into a front and a rear.

The front side (front), rear side (rear), wiping area and direction of movement of the cleaning device of the wiper strip are understood with reference to this definition, unless otherwise specified.

It should be noted that, the moving direction may be understood as a forward direction of the cleaning device, for example, if the cleaning device needs to be pushed by a user, the moving direction may be understood as a corresponding direction when the user pushes the cleaning device forward; if the cleaning device is a self-moving device, the direction of movement is understood to be the direction of travel of the self-moving device, i.e. the main direction of travel when the cleaning device is cleaning a surface to be cleaned. Although the cleaning device may also retract or turn in different situations, in the embodiments of the present application, the moving direction of the cleaning device refers to the main running direction such as the advancing direction of the cleaning device, the advancing direction of the user, and so on.

For this reason, referring to fig. 2 and 3, fig. 2 and 3 respectively show a structure of a cleaning device 100 according to an embodiment of the application, so as to prevent water and dust from leaking from two ends of the scraping strip, and further improve the cleaning effect of the cleaning device.

As shown in fig. 2 and 3, the cleaning device 100 is provided with a wiper 11 and an air outlet 21, the wiper 11 being used to wipe stains on a surface to be cleaned, the stains including solids or liquids, and the like. The air outlet 21 is disposed on the cleaning device 100, for example, on a bracket of the cleaning device 100, and the air outlet 21 may be disposed at an end portion of the cleaning device 100 near the scraper bar 11. When the cleaning device 100 uses the scraping strip 11 to scrape the surface to be cleaned, the air outlet 21 discharges air to the scraping strip 11 so as to bring the stains such as solid or liquid on the surface to be cleaned to the scraping area corresponding to the scraping strip 11, and then the scraping strip 11 is used for scraping and cleaning. By this, the water stain can be prevented from leaking from both end portions of the wiper strip 11 by the cooperation of the wiper strip 11 and the air outlet 21.

The number of the air outlets 21 may be at least two, and the at least two air outlets 21 are disposed on the cleaning device 100 and located at the outer sides of the two ends of the wiper 11, or may be located at the front, the front outer side, or the rear outer side of the end of the wiper 11, for driving the dirt to flow from the two ends of the wiper 11 to the middle portion of the wiping area corresponding to the wiper 11. The front is the front of the wiper 11 in the moving direction of the cleaning device 100, the outside is understood to be the range of the direction opposite to the end of the wiper 11, the front outside is understood to be the outside of the end of the wiper and is located in front of the wiper, and the rear corresponds to the front.

Specifically, as shown in fig. 3 and fig. 4, the two air outlets 21 are disposed opposite to each other, and the wiper strip 11 is located between the two air outlets 21, which can be understood that the air outlets 21 are directly corresponding to the ends of the wiper strip 11, so that the air outlet 21 can be used to drive the dirt to flow to the middle part of the wiping area corresponding to the wiper strip 11, so as to avoid the dirt side leakage at the two ends of the wiper strip 11.

In some embodiments, the air outlet 21 may be further provided with a preset inclination angle with the surface to be cleaned, and the air outlet 21 faces the end portion of the scraping strip 11, as shown in fig. 4, specifically, as shown in the right air outlet 21 in fig. 4, the air outlet 21 has a certain inclination angle with the surface to be cleaned, so that the air of the air outlet 21 is inclined downwards to blow the end portion of the scraping strip 11 and the surface to be cleaned, thereby better improving the cleaning effect of the scraping strip.

In some embodiments, the air outlet 21 may be located in front of the wiper 11 along the moving direction of the cleaning device 100, and blow air to both ends of the wiper 11, so as to drive the dirt to flow to the middle of the wiping area corresponding to the wiper 11.

In the embodiment of the present application, as shown in fig. 3, the scraping strip 11 may be located at the rear of the cleaning member 32 in the moving direction of the cleaning device 100, the air outlet 21 brings the stain to the middle position of the scraping zone corresponding to the scraping strip 11, and the stain is accumulated to the cleaning member 32 at the middle position so as to be cleaned by the cleaning member 32, so that not only the stain is prevented from leaking from the end side of the scraping strip 11, but also the stain is cleaned by the cleaning member 32, thereby further improving the cleaning effect.

In an embodiment of the present application, as shown in fig. 4 and 5, the cleaning member 32 may include a first endless cleaning belt 321 and a second endless cleaning belt 322, the first endless cleaning belt 321 and the second endless cleaning belt 322 may clean a surface to be cleaned, the first endless cleaning belt 321 and the second endless cleaning belt 322 may be rotated by a driving member, and garbage on the surface to be cleaned may be transferred to the recovery container 31 (may also be referred to as a garbage box).

It will be appreciated that the cleaning element 32 may also comprise an endless cleaning belt, such as a first endless cleaning belt 321, or a second endless cleaning belt 322.

In other embodiments, the cleaning element 32 may also include a sweeping element or a mopping element, such as a sweeping brush, a roller brush, a double roller brush, etc., and the mopping element may be a mop, a roller wrapped with cleaning fleece, a cleaning belt, etc., and the sweeping brush may include a disk brush, a side brush, etc. Of course, the cleaning member 32 may also include a combination of both sweeping and mopping members.

As shown in fig. 6, fig. 6 illustrates the structure of another cleaning device 100 according to an embodiment of the present application. The cleaning member 32 of the cleaning device 100 may specifically be a roller brush.

It should be noted that, in the embodiment of the present application, the wiper strip 11, the air outlet 21, and the cleaning member 32 may be referred to as a cleaning assembly.

In some embodiments, considering in combination the need for the air outlet 21 to carry dirt to the wiping area of the wiper strip 11 and how to carry dirt deposited by the wiper strip 11 to the waste bin with the cleaning member 32, the distance of the wiper strip 11 from the cleaning member 32 may be set in the range of 1cm to 5cm. This distance range can make things convenient for clean part 32 to clear up the accumulational spot of scraping strip 11, has avoided appearing accumulational spot too much and has led to appearing the side leakage from scraping the both ends of strip, and then has improved cleaning performance.

In some embodiments, in order to improve the side leakage preventing effect, when the position of the scraping strip 11 is set, the scraping strip 11 may be set to be located in the wind field range of the air outlet 21. The wind field range in which the wiper strip 11 is located at the air outlet 21 includes several cases: for example, the scraping strip 11 is located in the wind field range of the air outlet 21, and the scraping strip 11 corresponds to the air outlet 21, as shown in fig. 7; for example, the scraping strip 11 is located in the wind field range of the air outlet, but the scraping strip is located outside the caliber range of the air outlet, as shown in fig. 8. The wind field range is specifically shown as a range indicated by a broken line in fig. 7 and 8.

In some embodiments, in order to better improve the side leakage preventing effect of the end portion of the wiper strip 11, when the wiper strip 11 is disposed, a wind field area of the air outlet 21 located on the front side of the wiper strip 11 may be defined to be larger than a wind field area of the air outlet 21 located on the rear side of the wiper strip 11. Wherein the front side is the side not scraped by the scraper bar 11 in the moving direction of the cleaning device 100, and the rear side is the side already scraped by the scraper bar 11 in the moving direction of the cleaning device 100.

The wind field area of the wind outlet 21 on the front side of the scraping strip 11 is 2 times that of the wind field area of the wind outlet 21 on the rear side of the scraping strip 11, and this arrangement can effectively prevent the side leakage phenomenon at the two ends of the scraping strip 11, so as to improve the cleaning effect of the cleaning device.

In the embodiment of the present application, the air outlet of the air outlet 21 may be implemented by a fan. Illustratively, the cleaning apparatus 100 further comprises at least one air duct structure and at least one blower, for example, the air duct structure being connected to the air outlet 21; the fan is connected to the air duct structure whereby the fan provides a source of air to the air outlet 21 through the air duct structure. It will be appreciated that the provision of a wind source to the air outlet 21 is not limited to the manner in which the fan and duct arrangement is provided, for example, the air outlet of the fan may be provided as the air outlet 21. It is of course also possible to provide the air outlet 21 with a combination of a plurality of fans and an air duct structure.

As shown in fig. 8 and 9, the cleaning device 100 includes a wind tunnel structure 23 and a fan 24, the wind tunnel structure 23 is connected to the fan 24, the wind tunnel structure 23 is further connected to the air outlet 21, and the fan 24 is used for providing a wind source to the air outlet 21 through the wind tunnel structure 23.

In some embodiments, the air duct structure 23 may be disposed at a predetermined inclination angle with respect to the surface to be cleaned, so that the air outlet 21 forms a certain inclination angle with respect to the surface to be cleaned. For example, wind can be blown downwards from the obliquely upper direction of the scraping strip 11 so as to bring water stain to the middle position of the scraping strip 11, and side leakage at the end part of the scraping strip 11 can be better avoided.

In some embodiments, the air outlet 21 may be configured to be capable of outputting cool air or hot air. The air outlet 21 is preferably configured to be capable of discharging hot air, so that side leakage at the end of the scraping strip 11 can be avoided, and air drying of the surface to be cleaned can be accelerated.

Specifically, for example, the cleaning device 100 includes a heating device, such as a heating wire or a heating sheet, and the heating device may be disposed in the air duct structure 23, or may be disposed in the air outlet 21, or disposed near the air outlet 21, so that the air from the air outlet 21 may pass through the heating device to discharge the hot air to the surface to be cleaned and the scraping strip.

In summary, the various cleaning devices 100 provided in the embodiments of the present application each include the scraping strip 11 and at least two air outlets 21, and when the cleaning device 100 uses the scraping strip 11 to scrape a surface to be cleaned, the air outlets 21 are used to bring solid or liquid on the surface to be cleaned to the scraping area corresponding to the scraping strip 11, so that the air outlets 21 and the scraping strip 11 cooperate to avoid side leakage at the end of the scraping strip 11, thereby improving the cleaning effect.

As shown in fig. 10, since the scraping strip 11 is located at the rear of the movement direction of the cleaning device 100, the scraping strip 11 and the cleaning member 32 of the cleaning device 100 form the air guiding channel 320, and the air guiding channel 320 can strengthen the inner flow of the scraping strip 11, so that the side leakage at the end of the scraping strip 11 can be more effectively prevented.

In an embodiment of the present application, the wiper 11 may be provided on the cleaning device 100 by the fixing member 12, and in particular, the wiper 11 may be mounted on the fixing member 12 and then mounted on the housing of the cleaning device 100 by the fixing member 12, wherein the wiper 11 and the fixing member 12 constitute a wiper assembly 10, as shown in fig. 11.

In some embodiments, as shown in fig. 11, the air vent 102 may be formed in the scraping strip 11, where, because the scraping strip 11 and the cleaning component 32 of the cleaning device 100 form the air guiding channel 320, which is equivalent to providing the air vent 102 in the air guiding channel 320, the air flow in the air guiding channel 320 can be more convenient, and thus, the side leakage at the end of the scraping strip 11 can be more effectively prevented.

It will be appreciated that the vent 102 may also be provided in the mount 12. The number of the ventilation holes 102 may be one or more, and the shape of the ventilation holes 102 may be circular, square or rectangular, or other shapes, which are not limited herein.

Specifically, the vent hole 102 may be provided at a middle position of the wiper strip 11, or the vent hole 102 may be provided at a middle position of the mount 12. Of course, the vent 102 may be provided in other locations on the wiper strip 11 or the mounting member 12.

In some embodiments, as shown in fig. 12, the fixing member 12 includes a first fixing member 121 and a second fixing member 122, and the first fixing member 121 and the second fixing member 122 are used to clamp and fix the wiper strip 11. Utilize first mounting 121 and second mounting 122 centre gripping to scrape strip 11, because first mounting 121 and second mounting 122 can dismantle, and then make things convenient for the scraping strip 11 of damage to be changed in the future, improve clean effect.

In some embodiments, as shown in fig. 12, the first fixing member 121 further includes a first clamping groove 1210, and the second fixing member 122 further includes a second clamping groove 1220, and the first clamping groove 1210 and the second clamping groove 1220 are used to clamp the fixing portion 113 of the wiper strip 11. This can increase the stability of the wiper strip 11, so that loosening does not occur when the wiper strip 11 is used for removing liquid, and thus the cleaning effect can be improved.

Of course, it is understood that one of the first fixing member 121 and the second fixing member 122 may include a clamping groove, for example, the first fixing member 121 may further include the first clamping groove 1210, and the stability of the wiper strip 11 may be improved by one clamping groove.

It should be noted that the scraping strip 11 and the fixing member 12 may be integrally designed. For example, the fixing portion 113 of the wiper 11 is made of hard material, and the wiper portion 114 is made of soft material, wherein the fixing portion 113 may be configured as the fixing member 12, i.e., the fixing portion 113 may be understood as a fixing member. Thus, in embodiments of the present application, the wiper strip assembly 10 may include multiple components, such as the wiper strip 11 and the fastener 12, but may also include only one component of the wiper strip 11.

As shown in fig. 12, the wiper 11 may include a fixing portion 113 and a wiper portion 114, the wiper portion 114 extending from the fixing portion 113, the wiper portion 114 being for contacting a surface to be cleaned for wiping stains on the surface to be cleaned. Wherein, the thickness of the fixing portion 113 may be greater than that of the wiping portion 114, so that the fixing of the wiper 11 is facilitated, and the toughness of the wiper 11 during wiping may be increased, thereby improving the wiping effect.

In some embodiments, the wiper strip 11 may be made of a soft material to enhance cleaning. In some embodiments, the wiper 11 may be made of the same material, but may be made of a different material, such as one material for the fixing portion 113 and another material for the wiper portion 114, wherein the hardness of the fixing portion 113 is greater than the hardness of the wiper portion 114.

In some embodiments, in order to enhance the cleaning effect of the wiper 11, the portion of the wiper 114 that contacts the surface to be cleaned may be provided in a zigzag shape, and specifically, the bottom or front side of the wiper 114 may include a zigzag shape.

In some embodiments, as shown in fig. 13, the wiper strip 11 may include a plurality of sub-wiper strips 110 having an elongated shape, and the plurality of sub-wiper strips 110 constitute the wiper strip 11. When the wiper strip 11 including the plurality of sub-wiper strips 110 is used to wipe the ground, the cleaning effect of the ground can be improved, the combination form of the wiper strips 11 is enriched, and the user can decide how many sub-wiper strips 110 to use for combination, so that the cleaning effect can be improved, and the user experience can be improved.

In some embodiments, as shown in fig. 14a and 14b, the scraping strip 11 includes a plurality of elongated sub-scraping strips 110, and the plurality of sub-scraping strips 110 form the scraping strip 11, wherein the plurality of sub-scraping strips 110 have different heights, and when the plurality of sub-scraping strips 110 are mounted on the fixing member 12, the tops of the plurality of sub-scraping strips 110 are flush, and the tops are one end mounted on the fixing member 12, so that the distances from the bottoms of the plurality of sub-scraping strips 110 to the surface to be cleaned are different. That is, when the surface to be cleaned is not cleaned, the distances from the bottoms of the plurality of sub-wiper strips 110 to the surface to be cleaned are different, wherein the distance corresponding to the front sub-wiper strip 110 in the moving direction of the cleaning device 100 is greater than the distance corresponding to the rear sub-wiper strip 110 (h 1 > h2 > h 3), as shown in fig. 14 b. Therefore, stains on the ground can be cleaned by using different forces, and the cleaning effect can be further improved.

In some embodiments, the wiper strip 11 may be substantially elongated, as particularly shown in fig. 1; of course, the scraping strip 11 may also be in an encircling shape, as shown in fig. 15a, specifically, the encircling scraping strip 11 includes a strip-shaped body 111 and encircling arms 112, the two encircling arms 112 extend from the strip-shaped body 111 to two sides, the strip-shaped body 111 is approximately in a strip shape, the encircling arms 112 have a certain radian, the encircling direction of the encircling arms 112 faces the moving direction of the cleaning device, and the encircling direction of the encircling arms 112 can also be understood to face the front side of the scraping strip 11.

The encircling type scraping strip 11 is generally designed to be larger, that is, the coverage area of the encircling type scraping strip 11 is larger than the coverage area of the cleaning component of the cleaning device, so that the cleaned area of the cleaning component can be scraped, the encircling type scraping strip 11 can relatively improve the cleaning effect, but the two ends 101 of the encircling type scraping strip 11 also have water stain side leakage, so that the problem of the water stain side leakage cannot be really solved, and the cleaning effect is improved by repeated scraping.

When the encircling type scraping strip 11 is used for scraping the surface to be cleaned, the bottom of the scraping strip 11 needs to be propped against the surface to be cleaned, as the encircling arm 112 of the scraping strip 11 has a certain radian, a warping angle 1121 is formed at the contact part of the encircling arm 112 and the surface to be cleaned when the surface to be cleaned is propped against, and particularly as shown in fig. 15b, the formed warping angle 1121 also causes water stains to be omitted on the surface to be cleaned which is already scraped, so that the problem of end side leakage exists for the encircling type scraping strip, and the region corresponding to the encircling arm 112 also causes water stains to be omitted, so that the cleaning effect is affected.

It should be noted that, while the wiper 11 shown in fig. 15b forms one rake angle 1121, in actual situations, one or more rake angles 1121 may be formed, where the sizes of the rake angles 1121 may be the same or different.

For the encircling scraping strip 11, the cleaning device 100 provided by the application not only can solve the problem of side leakage at two ends of the encircling scraping strip 11, but also can solve the problem of spot omission caused by the warping angle formed by the encircling arm 112, thereby improving the cleaning effect of the cleaning device.

It should be noted that, according to the analysis of the encircling type scraping strip 11, since the two encircling arms 112 of the encircling type scraping strip 11 easily form a rake angle, in the embodiment of the present application, a combination of the scraping strip 11 having a substantially long shape and the air outlet 21 can be used, a better cleaning effect can be obtained, and the cost can be reduced by using the long scraping strip.

In the embodiment of the present application, as shown in fig. 4, the cleaning apparatus 100 further includes a driving mechanism 40, and the driving mechanism 40 is connected to the wiper strip assembly 10, specifically, the driving mechanism 40 is connected to the fixing member 12; the driving mechanism 40 is used for adjusting the distance between the scraping strip 11 and the surface to be cleaned, so that the scraping strip 11 can be lifted by the driving mechanism 40 to be separated from the surface to be cleaned when the cleaning device 100 does not need to remove liquid.

Since the wiper strip 11 and the attachment 12 can also be of unitary design, it is understood that the drive mechanism 40 is coupled to the wiper strip assembly 10, either to the attachment 12 or to the wiper strip 11.

In some embodiments, the driving mechanism 40 may specifically include a lifting mechanism and a rotating mechanism, where the lifting mechanism is connected to the wiper strip assembly 10, and may specifically be connected to the fixing member 12 of the wiper strip assembly 10, for driving the wiper strip assembly 10 to rise or fall; the rotating mechanism is connected with the scraping strip assembly 10 and is used for driving the scraping strip assembly 10 to rotate.

Wherein, the lifting mechanism comprises a power source for respectively realizing the lifting or descending of the scraping strip assembly 10; the rotation mechanism also includes a power source for effecting control of the rotation of the wiper strip assembly 10.

For example, the lifting mechanism includes a first motor and a lifting structure, where the first motor is connected to the lifting structure, specifically, for example, in a meshing manner, and the first motor drives the lifting structure to rise or fall, and the lifting structure is connected to the fixing member 12, so as to drive the scraping strip 11 to rise or fall.

Illustratively, the rotation mechanism includes a second motor that may be directly coupled to the rotational axis of the wiper strip assembly 10 for driving the wiper strip assembly 10 in rotation relative to the rotational axis. The rotation mechanism may of course also comprise a first gear and a second gear in a toothed connection, the first gear being connected with the rotation axis of the wiper strip assembly 10, the second gear being connected with a second motor, the second motor driving the wiper strip assembly 10 to rotate relative to the rotation axis via the second gear and the first gear. Since the wiper strip assembly 10 may be first lifted up to rotate, or first rotated to lift up, the rotating mechanism may be disposed on the wiper strip assembly 10, and then lifted up and down together with the wiper strip assembly 10, and after the wiper strip assembly 10 is lifted up to a preset position, the wiper strip assembly 10 is driven to rotate by the second motor of the rotating mechanism.

Of course, there are many other implementations of the drive mechanism 40 for controlling the raising, lowering and rotation of the wiper strip assembly 10, and this is not limiting.

In the embodiment of the present application, in order to make the size of the product more compact and miniaturized, the driving mechanism 40 may be designed to use only one power source (such as one motor), i.e., the lifting and rotation of the wiper strip assembly 10 may be controlled, thereby simplifying the control logic and saving electricity.

Specifically, as shown in fig. 16 and 17, the driving mechanism 40 includes a driving assembly 41, a link structure 42, and a tension member 43, wherein the driving assembly 41 is used for providing a driving force, the link structure 42 connects the driving assembly 41 and the wiper strip assembly 10, the driving assembly 41 drives the wiper strip assembly 10 to move through the link structure 42, and the tension member 43 is connected with the wiper strip assembly 10 for providing a tension force for the wiper strip assembly 10. Under the combined action of the link structure 42 and the tension member 43, the wiper strip assembly 10 is enabled to move toward the cleaning member 32, such as by driving the wiper strip assembly 10 to a predetermined position and rotating a predetermined angle, so that the wiper strip 11 of the wiper strip assembly 10 abuts the cleaning member 32.

It should be noted that the same reason is that the wiper strip 11 and the fixing member 12 may be integrally formed, and thus it is understood that the tension member 43 may be connected to the wiper strip assembly 10, or may be connected to the fixing member 12, or may be connected to the wiper strip 11.

The preset position can be designed according to actual requirements, for example, the common obstacles on the ground, such as carpets, need to be avoided when the preset position is lifted, so that a user can conveniently switch between a liquid removing mode and a liquid removing mode without using the cleaning device according to different scenes. The preset angle can also be designed according to actual requirements, for example, the height of the scraping strip 11 is combined to design the scraping strip 11 to rotate by the preset angle, so that the scraping strip 11 can be abutted against the cleaning component 32 of the cleaning device 100, and then self-cleaning of the scraping strip 11, namely, a self-cleaning mode of the scraping strip or a self-cleaning function of the scraping strip can be realized. The liquid removing mode is a mode of cleaning the floor by using the scraping strip.

In some embodiments, the drive mechanism 40 may include a drive assembly 41 and a linkage structure 42 without the use of a tension member 43. The driving component 41 is used for providing driving force, the connecting rod structure 42 is connected with the driving component 41 and the scraping strip component 10, the driving component 41 drives the scraping strip component 10 to move through the connecting rod structure 42, and the movement is that the driving component 41 drives the scraping strip component 10 to move, particularly to rise after rotating firstly through the connecting rod structure 42 due to the fact that the pulling force piece 43 does not work together.

It should be noted that, although the driving mechanism 40 may also be capable of driving the rotation and the lifting of the wiper strip assembly 10 without using the tension member 43, the rotation and lifting process is opposite to the process of using the tension member 43, and the tension member 43 is used to lift and then rotate. If the rotation is first followed by the ascent, it may have an effect on the switching of some modes of operation. For example, the cleaning device 100 needs to be designed to have a self-cleaning function of the wiper strip, the wiper strip 11 needs to be abutted against the cleaning member 32, the cleaning member 32 is utilized to clean the wiper strip 11, and the wiper strip 11 is inevitably blocked from rising by rotating and abutting against the cleaning member 32, and meanwhile, the wiper strip 11 may abut against the surface to be cleaned during rotation, so that a large driving force is required. Meanwhile, when the liquid removing mode is switched, for example, when the liquid removing mode is switched from the liquid removing mode to the liquid removing mode, the tension piece 43 is not used, the scraping bar assembly 10 can be rotated first and then ascended, but when the liquid removing mode is used, the scraping bar 11 of the scraping bar assembly 10 is abutted with the ground, and the abutted friction force does not utilize the rotation of the scraping bar 11, so that a large moment is required to be output by the motor of the driving assembly 41, and the motor of the driving assembly can be burnt when the situation is serious.

In some embodiments, as shown in fig. 18, the driving assembly 41 includes a motor 411 and a rotating member 412, the motor 411 may be provided on the housing 30 (bracket) of the cleaning device 100, the rotating member 412 is connected with a rotor of the motor 411, and the rotating member 412 can be rotated forward and backward by driving of the motor 411. The rotating member 412 is further configured to be connected to the link structure 42 to move the link structure 42.

Specifically, as shown in fig. 18, and in combination with fig. 17, the housing 30 may include a motor mounting area 301 thereon, the motor mounting area 301 being configured to mount the motor 411, and the motor 411 being mounted on the stand of the cleaning device 100, i.e., the motor mounting area 301, specifically by a motor mount 413.

In some embodiments, as shown in fig. 18, the linkage structure 42 includes a first linkage 421 and a second linkage 422, the first linkage 421 including opposite first and second ends, the first end of the first linkage 421 being coupled to the drive assembly 41, and in particular, being connectable to the rotary member 412 of the drive assembly 41; the second link 422 includes opposite first and second ends, the second end of the first link 421 being rotatably coupled to the first end of the second link 422, the second end of the second link 422 being rotatably coupled to the wiper strip assembly 41. The operating state of the link structure 42 can be referred to hereinafter with respect to the state of the wiper strip assembly 10.

In some embodiments, as shown in fig. 17, one end of the tension member 43 is connected to the bracket of the cleaning device 100, and the other end of the tension member 43 is connected to the wiper strip assembly 10, and may be specifically connected to the fixing member 12 of the driving assembly 10; wherein the pulling direction provided by the pulling member 43 is disposed at an angle to the rising direction of the wiper strip assembly 10. It should be noted that, in addition to the connection with the bracket of the cleaning device 100, one end of the tension member 43 may be connected to other components of the cleaning device 100, such as a cleaning component or a garbage can.

Specifically, as shown in fig. 18, the fixing member 12 is further provided with a first connecting member 123, and the other end of the tension member 43 is connected to the first connecting member 123. Facilitating the installation or removal of the tension member 43.

The tension member 43 is a member that can provide tension, and for example, the tension member 43 includes a spring, a rubber band, or the like. The number of tension members 43 may be one or more. As shown in fig. 17 and 18, for example, the number of tension members 43 is two, wherein the link structure 42 is located between the two tension members 43, thereby providing a relatively balanced tension. It should be appreciated that the tension provided by the tension member 43 not only provides the lifting power for the wiper strip assembly 10, but also cooperates with the linkage structure 42 to enable the wiper strip assembly 10 to be lifted to a predetermined position and rotated by a predetermined angle.

The above-mentioned ascending and then rotating process, or the ascending process after rotating, does not mean that there is no rotation at all in the ascending process, or there is no ascending in the rotating process, but there is a slight rotation accompanying the ascending process, but the ascending is mainly represented as ascending; the rotation is accompanied by a slight increase, and is mainly represented by rotation. For example, a process that mainly shows rising and then mainly shows rotation is referred to as a rising-before-rotation process, and a process that mainly shows rotation and then mainly shows rising is referred to as a rotation-before-rising process.

In some embodiments, as shown in fig. 18, the link structure 42 further includes a mounting seat 423, where the mounting seat 423 is mounted on a support of the cleaning device 100, and the first end of the first link 421 is rotatably connected to the mounting seat 423, so as to increase the rotational stability of the first link 421.

In some embodiments, as shown in fig. 18, the wiper strip assembly 10 may also include a second connector 124, or it may be understood that the fixing member 12 includes a second connector 124, where the second connector 124 is disposed inside the upper end of the wiper strip assembly 10, and in particular, may be disposed inside the upper end of the fixing member 12; the second end of the second link 422 is rotatably coupled to the wiper strip assembly 10 by the second coupler 124. Wherein the second connecting member 124 may be detachably connected to the fixing member 12 or may be integrally designed with the fixing member 12.

It should be noted that, the upper end of the wiper strip assembly 10 is an end of the wiper strip assembly 10 away from the surface to be cleaned, specifically, an end of the fixing member 12 away from the surface to be cleaned, and the inner side of the upper end is a side of the upper end, which is close to the cleaning member 32 of the cleaning device 100. The power of the driving assembly 41, in particular the motor, can be saved, and the rotation of the scraper assembly can be controlled by outputting smaller moment.

In some embodiments, as shown in fig. 17, the cleaning device 100 includes a guide 44, the guide 44 being coupled to the wiper strip assembly 10, the guide 44 being configured to guide movement of the wiper strip assembly 10, such as to guide lifting and rotation of the wiper strip assembly 10. The guide 44 may include a square groove or a waist groove. The guide 44 may provide for a better fit with the linkage structure 42 or tension member 43 to provide motion control of the wiper strip assembly 10.

Specifically, the number of the waist-shaped grooves is two, and the two waist-shaped grooves are opened on the bracket of the cleaning device 100 and are opposite. The connecting posts 125 are disposed at two side ends of the wiper strip assembly 10, and specifically, the connecting posts 125 are disposed at two side ends of the fixing member 12. Each of the waist-shaped grooves is rotatably provided through one of the connection posts 125, thereby guiding the movement of the wiper strip assembly 10, including elevation and rotation guides, etc.

In an embodiment of the present application, the driving mechanism 40 may adjust the distance between the wiper 11 and the surface to be cleaned, and drive the wiper 11 to move toward the cleaning member of the cleaning device 100. Specifically, through the design of the connecting rod structure 42, the scraper assembly 10 can be driven to rise and rotate and the scraper assembly 10 can be driven to descend, so that the scraper assembly 10 has three states, namely a descending state, a rising state and a rotating state.

In the lowered state, as shown in fig. 19a and 19b, the driving mechanism 40 drives the wiper strip assembly 10 to descend, the wiper strip 11 of the wiper strip assembly 10 presses against the floor, and the floor can be wiped as the cleaning device 100 moves, that is, the cleaning device 100 performs the liquid removing mode. It should be noted that, due to the design of the link structure 42, the wiper strip 11 may be inclined to the rear side of the wiper strip 11 during the descent, i.e., the inclination angle θ in fig. 19 b. Therefore, when the scraping strip 11 is pressed against the ground, the scraping part of the scraping strip 11 can be fully contacted with the ground, and the cleaning effect is further improved.

In the raised state, as shown in fig. 20a and 20b, the driving mechanism 40 drives the wiper strip assembly 10 to rise, the wiper strip 11 of the wiper strip assembly 10 is separated from the floor, and the cleaning device 100 can be understood as canceling the liquid removing mode.

As shown in fig. 21a and 21b, the driving mechanism 40 drives the wiper strip assembly 10 to rise to a preset position, specifically, a top end position of the guide (waist-shaped groove) 44, and continues to drive the wiper strip assembly 10 to rotate, so that the wiper strip 11 abuts against the cleaning member 32 (the first annular cleaning belt 321), and the cleaning member 32 is utilized to perform self-cleaning on the wiper strip 11, which is understood as the cleaning device 100 executing the wiper strip self-cleaning mode.

In some embodiments, the cleaning device 100 has a liquid removing mode in which the driving mechanism 40 drives the scraping bar 11 to press against the surface to be cleaned, and the surface to be cleaned is scraped to remove liquid from the surface to be cleaned. Specifically, the liquid removing mode may be selected by setting a mode key on the cleaning device 100, or by setting a touch screen, and displaying the liquid removing mode on the touch screen for the user to select.

For example, in one scenario, if the user wants to use the liquid removing mode of the cleaning device 100, the liquid removing mode may be selected through the mode button, and when the cleaning device 100 is in the liquid removing mode, the driving mechanism 40 drives the scraping strip 11 to press against the surface to be cleaned, so as to perform liquid removing cleaning on the surface to be cleaned. If the user takes the liquid removal mode, the wiper strip 11 can be lifted off the surface to be cleaned by the drive mechanism 40.

For another example, if a floor surface is encountered where the liquid removal mode is unavailable, such as carpeted, the user may cancel the liquid removal mode and the drive mechanism 40 lifts the blade 11 off of the surface to be cleaned when the cleaning device 100 is in the liquid removal mode.

In some embodiments, the drive mechanism 40 is also used to rotate the lifted wiper strip 11 such that the wiper strip 11 abuts the cleaning member 32 of the cleaning device 100 to achieve self-cleaning of the wiper strip 11 with the cleaning member 32. Therefore, the scraping strip does not need to be manually cleaned by a user, and the experience of the user is improved.

The cleaning device 100 has a self-cleaning function for the wiper strip 11, i.e., cleaning of the wiper strip 11 is performed by the cleaning member 32. The self-cleaning function can perform self-cleaning on the scraping strip 11 in the working process of the cleaning device 100, wherein the working process is the process of cleaning the surface to be cleaned; naturally, the wiper strip 11 may be self-cleaned when the cleaning device 100 is not in operation.

For example, in one scenario, when the cleaning device 100 is used to remove liquid from the floor, if the floor has small hard objects, such as rice grains, the small hard objects may adhere to the wiping portion 114 of the wiper 11, thereby affecting the liquid removal effect of the wiper 11. If the user finds that the liquid removing effect is not good, the user can select the self-cleaning function of the cleaning device 100 to clean the scraper bar 11, thereby improving the liquid removing effect.

As another example, in another scenario, such as when the user begins to use the cleaning device 100, such as when the user is concerned that the wiper strip 11 may be stuck with debris; or when the user finishes using the cleaning device 100, there is a fear that the scraping strip 11 may be stuck with garbage to affect the next liquid removing effect, and the user can select the self-cleaning function of the cleaning device 100 to clean the scraping strip 11, thereby improving the liquid removing effect.

In some embodiments, the cleaning device 100 further comprises a disinfecting assembly for disinfecting the scraper bar 11 or the surface to be cleaned, and/or a drying assembly. Specifically, the sterilizing module is located at the front side of the wiper strip 11 in the moving direction of the cleaning device 100. Of course, in other embodiments, the sterilizing assembly is located at the rear side of the wiper strip 11 in the direction of movement of the cleaning device 100. The disinfection component can be an ultraviolet lamp tube, and is a liquid outlet component, and the scraping strip 11 and the ground are disinfected by spraying disinfectant. The drying component is used for drying the scraping strip 11 or the surface to be cleaned. Wherein the drying assembly may be located at the rear side of the scraper bar 11 in the moving direction of the cleaning device 100. The drying assembly may be an infrared lamp or other heat generating device such as a heating device or the like.

The cleaning device provided by each embodiment at least comprises the scraping strip and the air outlet, when the cleaning device uses the scraping strip to scrape the surface to be cleaned, the air outlet is used for bringing the solid or liquid of the surface to be cleaned to the scraping area corresponding to the scraping strip, the scraping strip is used for cleaning the stains on the surface to be cleaned, and meanwhile, the side leakage at the end part of the scraping strip of the cleaning device can be avoided, so that the cleaning effect of the cleaning device is improved.

While the application has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
