Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and in particular, to a cleaning equipment. Background Art

[0002] In modern society, cleaning equipment such as floor scrubbers is widely used in commercial environments, hospitals, schools, office buildings, warehouses, and households. Its principle is to clean the stains on the cleaning ground by means of a high-speed rotating brush or a roller brush combined with a cleaning agent and water. After the cleaning is completed, a squeegee is used to clean the accumulated water on the roller brush. The traditional floor scrubber cannot adjust the distance between the squeegee and the roller brush. Therefore, after the cleaning equipment is used for a long time, the roller brush is worn, resulting in a change in the diameter of the roller brush. For this reason, the constant squeegee can no longer provide a good scraping force.

[0003] Therefore, a passive floating squeegee has emerged on the market now, that is, a reset member such as a spring is used to always press the squeegee, so as to ensure that the pressure of the squeegee on the roller brush is almost constant. However, this squeegee also cannot cope with different usage scenarios of the roller brush. For example, when the water volume on the ground is large, the water absorption of the roller brush suddenly increases. If the pressure of the squeegee remains constant, the excess sewage cannot be squeezed out of the roller brush at this time. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a cleaning equipment.

[0005] In order to achieve the above purpose, the technical solution provided by an embodiment of the utility model is as follows:

[0006] A cleaning equipment, comprising: a body, on which a sewage tank and a main motor are arranged; a floor brush, which is arranged at the lower end of the body and is used to suck the dirt on the surface to be cleaned into the sewage tank. The floor brush includes: a housing; a driving member, which is arranged in the housing; a roller brush, which is rotatably arranged in the housing; a liquid distributor, which is arranged towards the roller brush to spray liquid on the roller brush; a transmission member, the driving member is drivingly connected with the transmission member and enables the transmission member to move along a first direction, and the first direction is the direction parallel to the axis of the roller brush; a water scraping assembly, the water scraping assembly is arranged closer to the roller brush relative to the transmission member, and the water scraping assembly is at least used to control the water content of the roller brush. A sliding surface for guiding and sliding is arranged on the transmission member and the water scraping assembly. When the transmission member moves along the first direction, the floor brush is in a strong state, and the strong state means that the roller brush rotates, the body tilts, the main motor sucks, and the water scraping assembly moves towards the roller brush.

[0007] It should be understood that in the current prior art, cleaning equipment such as floor scrubbers will encounter many scenarios during cleaning, such as water stains, that is, there is a lot of water on the surface to be cleaned. At this time, the roller brush will absorb a lot of water. Therefore, if the water on the roller brush is not squeezed out in time, the roller brush will no longer be able to absorb water. At the same time, an overly wet roller brush will also cause too much water stains to remain on the ground.

[0008] Another example is a stubborn stain environment. When relatively sticky dirt, such as oil stains, appears on the surface to be cleaned, an ordinary scraper does not have sufficient ability to remove the sticky dirt.

[0009] In addition, if the dirty liquid absorbed by the roller brush during the previous cleaning process cannot be squeezed out and cleaned up in time, the residual dirty liquid will continue to contaminate the floor during the subsequent cleaning process, making the cleaned floor "mopping is equivalent to not mopping" or "mopping makes it even dirtier".

[0010] To this end, this case provides a solution with a strong state. When encountering the above scenario, the floor brush can be controlled to enter the strong state. In the strong state, the wiper component can exert a greater extrusion force on the roller brush. The fluff on the roller brush can produce a greater forced deformation after being subjected to a greater extrusion pressure, so that more dirty liquid absorbed in the fluff can be squeezed out, and the dirty liquid on the roller brush can be squeezed out and cleaned up in a timely and efficient manner. Not only can the cleanliness of the roller brush be quickly restored, but also the ability of the roller brush to absorb dirty liquid can be restored, so that the roller brush can absorb more dirt in the subsequent cleaning process to prevent excessive water stains from remaining on the ground.

[0011] Alternatively, the floor brush enters a strong state, in which the wiper assembly can exert a greater squeezing force on the roller brush. In conjunction with the rotation of the roller brush, the fluff on the roller brush is subjected to a greater scraping friction from the wiper assembly, so that the stubborn and sticky dirt absorbed in the fluff can be scraped off the fluff more easily, and even the hair dirt entangled on the roller brush can be scraped off more easily, which not only can clean stubborn stains, but also can solve the problem of hair entanglement.

[0012] Of course, it should be understood that the above-mentioned strong state is not limited to the cleaning state of the floor scrubber, and it can also be applied during self-cleaning or drying.

[0013] Through the above-mentioned floor brush, the wiper assembly can be controlled to move toward the roller brush as needed, so that the floor brush forms a strong state. In the strong state, the roller brush is in a rotating state, the liquid distributor sprays liquid synchronously, and the wiper assembly moves and approaches the roller brush. In this way, the contact between the wiper assembly and the roller brush can be closer, and more water or stains on the roller brush can be scraped off.

[0014] Imagine that when there is a lot of water on the ground, a normal floor brush takes a long time to suck it up completely. However, when the floor brush enters the strong power state, the water scraping component gradually approaches the roller brush, enabling it to scrape more water off the roller brush, which directly enhances the water absorption capacity of the roller brush. As a result, the water on the ground can be quickly sucked up, providing a better user experience.

[0015] Or in the scenario of stubborn stains, since the water scraping component of the normal floor brush cannot move as required, the sticky stains on the roller brush cannot be removed, and the floor becomes dirtier and dirtier during the cleaning process. With this solution, the floor brush can enter the strong power state, and the water scraping component gradually gets closer to the roller brush, thus being able to scrape off the above-mentioned dirt.

[0016] Moreover, the water scraping component moves by sliding. Its lateral movement is transformed into a linear movement towards the roller brush, and through the cooperation of the sliding surface, the driving contact surface of the water scraping component is larger, making the movement of the water scraping component more stable.

[0017] Imagine that if a linear motor or the like is used to directly push the water scraping component to move back and forth, the connection part is an approximate point contact with a small contact surface. Therefore, during the movement of the water scraping component, it is prone to deformation due to force problems. At the same time, due to the problem of structural arrangement, the contact point between the transmission part and the water scraping component is not necessarily at the central position, and the force is uneven.

[0018] The method of contacting through the sliding surface can effectively solve the above problems. Using the sliding surface can effectively increase the contact area, with more uniform force and more stable movement.

[0019] Meanwhile, it should be understood that the longitudinal dimension of the floor brush of the existing floor washing machine is relatively limited and small. The current solution can be applied to the floor brush in the existing technology without breaking the traditional floor brush shape of the floor washing machine, as follows.

[0020] When it is necessary to perform forward and backward movement, in the current existing technology, either a cam is used, or a linear motor or a cylinder is used. However, whether it is the above-mentioned cam or linear motor, etc., the movement distance is controlled by the size of a single structure. Therefore, it must be installed in the front-back direction, resulting in a relatively large size required to be reserved in the front-back direction. Taking the cylinder as an example, the size to be reserved is the size of the cylinder block plus the size of the rod part, that is, almost twice the size of the cylinder. The current solution is to convert the lateral sliding into forward and backward movement. Therefore, its size occupies more in the lateral space, making the overall structure of the floor washing machine more compact and not affecting the size arrangement of the floor brush structure in the current existing technology.

[0021] Further, there is an angle between the guiding sliding direction of the sliding surface and the first direction, and the angle is not zero, so that the transmission member can drive the wiper assembly to approach or move away from the roller brush along the second direction, and the second direction is perpendicular to the first direction. When there is a lot of water on the ground and the floor brush needs to be adjusted to the strong state, the guiding sliding direction of the sliding surface is arranged at an angle with the first direction, which is beneficial to the movement of the transmission member driving the wiper assembly, and can facilitate the wiper assembly to scrape the water on the roller brush.

[0022] Further, one of the transmission member and the wiper assembly is provided with a concave portion, and the other of the transmission member and the wiper assembly is provided with a convex portion. At least a part of the convex portion extends into the concave portion, and the sliding surface of the concave portion is in sliding fit with the sliding surface of the convex portion; or both the transmission member and the wiper assembly are provided with convex portions, and the sliding surface of the convex portion of the transmission member is in sliding fit with the sliding surface of the convex portion of the wiper assembly. When the floor brush finishes absorbing water and the water on the roller brush needs to be scraped off, through the concave-convex fit or the fit between the convex portions, the transmission member is enabled to squeeze the wiper assembly to complete the movement of the wiper assembly along the second direction.

[0023] Further, the first direction and the second direction are set to form a reference plane, the extending direction of the sliding surface is within the reference plane, and there is an angle between the extending direction of the sliding surface and the second direction, and the angle is not zero. Taking the strong state as an example, the direction of the roller brush axis is the first direction, and the forward direction when the floor brush cleans the accumulated water on the ground is the second direction. By arranging the extending direction of the sliding surface at an angle with the second direction, it is beneficial for the driving member to drive the wiper assembly to approach the roller brush through the transmission member.

[0024] Further, the floor brush further includes a control unit. When the floor brush is in the strong state, the driving member receives a signal from the control unit to adjust the distance between the wiper assembly and the roller brush. When it is necessary to quickly clean the accumulated water on the ground, it is necessary to make the floor brush in the strong state. By sending a control signal from the control unit to control the driving member, the moving distance of the transmission member and the wiper assembly is shortened, so that the wiper assembly approaches the high-speed rotating roller brush to achieve rapid drainage of the roller brush.

[0025] Further, the floor brush is configured with a self-cleaning state, where the floor brush is located on an external base station, the roller brush rotates, the liquid distributor sprays water, the water scraping assembly approaches or moves away from the roller brush, and the control unit includes: a detection component for detecting the current value of the roller brush; and a control component for controlling the distance between the water scraping assembly and the roller brush according to the detected current value. After the accumulated water on the ground has been cleaned by the floor brush and it is necessary to clean the floor brush for the next use, for the floor brush in the self-cleaning state, the roller brush rotates and the water scraping assembly approaches the roller brush. During this process, the detection component can detect the current value on the roller brush and transmit the detected current value to the control component. According to the magnitude of the current value detected by the detection component, the control component adjusts the driving state of the driving component. If the current value is too large, it indicates that the scraping force between the water scraping assembly and the roller brush is too large. At this time, the driving component reversely drives the transmission component to move the water scraping assembly away from the roller brush to prevent the roller brush from being burned due to an excessive current value on the roller brush. After receiving the current value, it can automatically adjust the driving state of the driving component to achieve automatic adjustment between the water scraping assembly and the roller brush.

[0026] Further, the floor brush is configured with a drying and flexible state, where the floor brush is located on an external base station, the liquid distributor does not spray liquid, the water scraping assembly intermittently approaches or moves away from the roller brush, and the base station performs a drying action on the roller brush; the control unit includes a detection component and a control component, and the control component controls the water scraping assembly to intermittently approach or move away from the roller brush according to the signal obtained by the detection component. After the floor brush has completed cleaning the ground and self-cleaning, if the roller brush is in a wet state and is stored, the roller brush is prone to generating odors and mildew, which can affect the service life of the roller brush and the user experience. By switching the floor brush to the drying and flexible state, the roller brush keeps rotating, and the control component controls the water scraping assembly to intermittently approach or move away from the roller brush, thereby cooperating with the base station for drying, which can achieve a better drying effect. Specifically, during the drying process, by approaching and moving away intermittently, the overturning state of the hairs on the roller brush can be changed, thereby cooperating with the base station to achieve a better drying effect.

[0027] Further, the water scraping assembly includes a water scraping member and a connecting member. The connecting member is connected to the water scraping member and has a sliding surface, and the water scraping member is used to abut against the roller brush. When the floor brush needs to be in multiple different working states to achieve the effects of cleaning the ground, self-cleaning, and drying the roller brush, the sliding surface of the transmission member cooperates with the sliding surface of the connecting member, and the sliding surface on the transmission member squeezes the sliding surface on the connecting member to drive the water scraping member to squeeze the roller brush.

[0028] Further, the connecting member is fixedly arranged on the wiper member; or at least a part of the connecting member is movable relative to the wiper member. During the long-term cleaning process of the floor brush, the wiper assembly repeatedly approaches the roller brush. When the connecting member is fixedly arranged on the wiper member, rapid transmission can be achieved and it is convenient for assembly. While when at least a part of the connecting member is movable relative to the wiper member, soft contact between the wiper member and the roller brush can be realized. The connection mode between the wiper member and the connecting member can be reasonably selected according to actual needs.

[0029] Further, the connecting member includes a first connecting member and a second connecting member that can move relative to each other. The first connecting member has a sliding surface, the second connecting member is fixed to the wiper member, and both the first connecting member and the second connecting member can move along the second direction. By providing a sliding surface on the first connecting member and using the transmission member to squeeze the first connecting member to achieve relative movement between the first connecting member and the second connecting member, and then to achieve the wiper member squeezing the roller brush. When there is water accumulation on the ground, the floor brush starts, the roller brush rotates to clean the water accumulation, the transmission member squeezes the first connecting member through the sliding surface, the first connecting member approaches the second connecting member along the second direction and then drives the wiper member to approach the roller brush. By the way that both the first connecting member and the second connecting member move along the second direction, it is realized that the transmission member drives the first connecting member and the second connecting member to move successively along the second direction, and the frictional force transition between the roller brush and the wiper member is achieved.

[0030] Further, the first connecting member and the second connecting member are hooked and matched so that when the wiper assembly moves in a direction away from the roller brush, the first connecting member pulls the second connecting member and the wiper member. Through the hooking and matching method, the movement of the second connecting member driven by the first connecting member is realized. When the floor brush needs to be stored after completing the cleaning work, the floor brush is in a dry and flexible state. The wiper assembly periodically approaches or moves away from the roller brush. When the transmission member drives the first connecting member away from the roller brush, since the first connecting member and the second connecting member are hooked and matched, the second connecting member is pulled away from the roller brush, and finally the wiper member moves away from the roller brush, ending the squeezing and cleaning of the roller brush.

[0031] Further, the second connecting member has a limiting hook, and a hanging groove adapted to the limiting hook is arranged on the first connecting member. By opening a hanging groove on the first connecting member, the limiting hook on the second connecting member realizes the hooking and matching between the first connecting member and the second connecting member. In the dry and flexible state, the wiper assembly periodically moves away from the roller brush, and the driving member drives the first connecting member away through the transmission member. At this time, the distance between the first connecting member and the second connecting member is relatively close, and the movement of the first connecting member will not drive the second connecting member and the wiper member to move until the groove wall of the hanging groove abuts against the limiting hook. After the abutment, the first connecting member drives the second connecting member to move to realize the wiper member moving away from the roller brush.

[0032] Further, the wiper assembly further includes an elastic member disposed between the first connecting member and the second connecting member to floatingly connect the first connecting member and the second connecting member. When the floor brush starts to clean, self-clean, or dry the roller brush, after the first connecting member is squeezed by the transmission member, one end of the elastic member is squeezed by the first connecting member, and the other end of the elastic member abuts against the second connecting member. After the elastic member is compressed, the elastic force of the elastic member drives the second connecting member to move, realizing the elastic connection between the first connecting member and the second connecting member.

[0033] Further, there are multiple groups of sliding surfaces. Each group of sliding surfaces includes two sliding surfaces respectively disposed on the transmission member and the wiper assembly, and the multiple groups of sliding surfaces are respectively and spacedly disposed on the wiper assembly and the transmission member. There may be not only accumulated water but also foreign objects on the ground. During the cleaning process, if foreign objects enter the floor brush, it is easy to cause the wiper assembly to tilt, resulting in a decrease in the wiper effect. By setting multiple groups of sliding surfaces, when the transmission member drives the wiper assembly to move, the moving distance of the wiper assembly is stable, and at the same time, the effectiveness of the movement is ensured.

[0034] Further, a gear structure is provided at the output end of the driving member, and a rack structure is provided on the transmission member. The rack structure meshes with the gear structure, and the extending direction of the rack structure is parallel to the first direction. After the floor brush is started, the rotation of the output end of the driving member is converted into the movement of the transmission member along the first direction through the cooperation of the gear and the rack, and then the wiper assembly is moved along the second direction through the sliding surface to realize the wiper assembly scraping the roller brush.

[0035] The utility model has the following beneficial effects:

[0036] Through the above floor brush, the wiper assembly can be controlled to move towards the roller brush according to requirements, so that the floor brush forms a strong state. In the strong state, the roller brush is in a rotating state, the body is tilted, the main motor sucks, and the wiper assembly moves and approaches the roller brush. In this way, the contact between the wiper assembly and the roller brush can be made closer, and more water on the roller brush can be scraped off, so that the water absorption capacity of the roller brush is stronger, and the position of the wiper strip can be adjusted arbitrarily. Therefore, the present application solves the problem that the position of the wiper strip of the floor washer in the prior art cannot be adjusted. Description of the Drawings

[0059] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0060] Next, the technical solutions in the present utility model will be described with reference to the accompanying drawings.

[0061] In order to solve the problem that the position of the squeegee of the floor washer in the prior art cannot be adjusted, the present utility model provides a cleaning device.

[0062] In order to achieve the above object, the technical solutions provided by an embodiment of the present utility model are as follows:

[0063] As Figures 1 to 8 shown, the cleaning device includes a body and a floor brush. A sewage tank and a main motor (not shown in the figure) are provided on the body. The floor brush is arranged at the lower end of the body and is used to suck the dirt on the surface to be cleaned into the sewage tank. The floor brush includes a housing 90, a driving member 10, a roller brush 100, a liquid distributor, a transmission member 20, and a water scraping assembly 30. The driving member 10 is arranged in the housing 90. The roller brush 100 is rotatably arranged in the housing 90. The liquid distributor is arranged facing the roller brush 100 for spraying liquid on the roller brush 100. The driving member 10 is drivingly connected to the transmission member 20 and enables the transmission member 20 to move in a first direction, and the first direction is the direction parallel to the axis of the roller brush 100. The water scraping assembly 30 is arranged closer to the roller brush 100 relative to the transmission member 20. The water scraping assembly 30 is at least used to control the water content of the roller brush 100. The transmission member 20 and the water scraping assembly 30 are provided with sliding surfaces that cooperate with each other for guiding, so that the transmission member 20 can drive the water scraping assembly 30 to approach or move away from the roller brush 100 in a second direction. When the transmission member 20 moves in the first direction, the floor brush is in a strong state, and the strong state means that the roller brush 100 rotates, the body is tilted, the main motor sucks, and the water scraping assembly 30 moves towards the roller brush 100.

[0064] Through the above-mentioned floor brush, the wiper assembly 30 can be controlled to move towards the rotary brush 100 according to requirements, so that the floor brush forms a strong state. In the strong state, the rotary brush 100 is in a rotating state. The liquid distributor can control synchronous liquid spraying, and the wiper assembly 30 moves and approaches the rotary brush 100. In this way, the contact between the wiper assembly 30 and the rotary brush 100 can be made closer, and more water on the rotary brush 100 can be scraped off, so that the water absorption capacity of the rotary brush 100 is stronger.

[0065] Imagine that when there is a lot of water on the ground, it takes a long time for a normal floor brush to suck it clean. However, when the floor brush enters the strong state and the wiper assembly 30 gradually approaches the rotary brush 100, more water on the rotary brush 100 can be scraped off, that is, the water absorption capacity of the rotary brush 100 directly increases. Then the ground can quickly suck off the water, and the user experience will be better. Of course, the above-mentioned strong state is not only used in the case of more water, but also can play a good role in a relatively viscous environment.

[0066] In this embodiment, there is an included angle between the guiding sliding direction of the sliding surface and the first direction, and the included angle is not zero, and the second direction is perpendicular to the first direction. When there is a lot of water on the ground and the floor brush needs to be adjusted to the strong state, the guiding sliding direction of the sliding surface is arranged at an included angle with the first direction, which is beneficial for the transmission member 20 to drive the movement of the wiper assembly 30, and it is convenient for the wiper assembly 30 to scrape the water on the rotary brush 100.

[0067] It should be noted that through the transmission and conversion of forces between different structural members, the movements of the transmission member 20 and the wiper assembly 30 are not on the same straight line, effectively avoiding the reaction force of the force. The wiper assembly 30 needs to contact the rotary brush 100 and receive the reaction force from the second direction, while the transmission member 20 can only move along the first direction. Therefore, the acting force in the second direction cannot directly push the transmission member 20 moving in the first direction, that is, the transmission member 20 will not be directly stressed in the second direction either. Thus, it is ensured that the wiper assembly 30 can effectively and stably contact the rotary brush 100, thereby ensuring the water scraping effect.

[0068] In this embodiment, through the sliding surface with a certain slope, the movement relationship between the transmission member 20 and the wiper assembly 30 can be effectively ensured, and there will be no excessive loss of force. While ensuring the conversion of the movement direction, the transmission force is not consumed, thereby ensuring the movement reliability and stability of the wiper assembly 30.

[0069] Of course, if it is necessary to further reduce the loss of transmission force, a rolling structure can also be considered to be arranged between the sliding surfaces moving relative to each other, so as to reduce friction. However, in actual use, necessary friction is also beneficial. Excessive pursuit of low friction may lead to too high adjustment sensitivity and faster response speed. Therefore, it is necessary to reasonably adjust the situation at the sliding surface in combination with the actual use requirements.

[0070] As Figure 5 , Figures 9 to 10 , and Figures 12 to 13 shown, a recess 40 is provided on one of the transmission member 20 and the wiper assembly 30, and a protrusion 50 is provided on the other of the transmission member 20 and the wiper assembly 30. At least a part of the protrusion 50 extends into the recess 40, and the sliding surface of the recess 40 is in sliding fit with the sliding surface of the protrusion 50.

[0071] When the water on the roller brush 100 needs to be scraped off after the local brush finishes absorbing water, through the setting of concave-convex engagement, the movement of the sliding surface can be better guaranteed. Therefore, the engagement setting of the protrusion 50 and the recess 40 can effectively make the sliding surfaces of the two structures fit together, ensuring effective sliding contact between the sliding surfaces, and can less avoid the problem of sliding failure caused by the separation of the two sliding surfaces. Therefore, the mutually cooperating protrusion 50 and recess 40 actually further play the role of guiding and limiting, and further ensure the movement stability and reliability of the wiper assembly 30.

[0072] Of course, it doesn't mean that the movement of the sliding surface must be achieved by the cooperation of the recess 40 and the protrusion 50. In an embodiment not shown, protrusions 50 can also be provided on both the transmission member 20 and the wiper assembly 30, and the sliding surface of the protrusion 50 of the transmission member 20 is in sliding fit with the sliding surface of the protrusion 50 of the wiper assembly 30. By adopting this method, the relative movement of the transmission member 20 and the wiper assembly 30 can also be achieved. The specific setting situation also needs to be comprehensively considered according to the installation space of the overall product and the specific setting requirements.

[0073] Specifically, in this embodiment, the recess 40 is an inclined groove, and the protrusion 50 is an inclined protruding rib. The inclination here is relative to the first direction and the second direction. Through the concave-convex cooperation or the cooperation between the protrusions 50, the transmission member 20 squeezes the wiper assembly 30 to complete the movement of the wiper assembly 30 in the second direction. As Figure 5 and Figure 10 shown, a recess 40 or a protrusion 50 is provided at the end of the transmission member 20 opposite to the wiper assembly 30.

[0074] In this embodiment, there are multiple sets of sliding surfaces. Each set of sliding surfaces includes two sliding surfaces respectively arranged on the transmission member 20 and the wiper assembly 30. The multiple sets of sliding surfaces are respectively arranged on the wiper assembly 30 and the transmission member 20 at intervals. There may be not only accumulated water but also foreign objects on the ground. During the cleaning process, if foreign objects enter the floor brush, it is easy to cause the wiper assembly 30 to tilt, resulting in a decline in the wiper effect. By setting multiple sets of sliding surfaces, when the transmission member 20 drives the wiper assembly 30 to move, the moving distance of the wiper assembly 30 is stable, and at the same time, the effectiveness of the movement is ensured.

[0075] Specifically, when cleaning the accumulated water on the ground for a long time, the transmission member 20 needs to repeatedly press the sliding surface on the wiper assembly 30, and the sliding surface is prone to wear and even failure. Therefore, when there are multiple concave portions 40 or convex portions 50, the multiple concave portions 40 or multiple convex portions 50 are arranged at intervals. When a certain concave portion 40 or convex portion 50 fails, the floor brush can still operate normally.

[0076] In this embodiment, the first direction and the second direction form a reference plane. The extending direction of the sliding surface is within the reference plane, and there is an angle between the extending direction of the sliding surface and the second direction and the angle is not zero. Taking the strong force state as an example, the direction of the axis of the rotary brush 100 is the first direction, and the forward direction when the floor brush cleans the accumulated water on the ground is the second direction. By setting the extending direction of the sliding surface to form an angle with the second direction, it is beneficial for the driving member 10 to drive the wiper assembly 30 to approach the rotary brush 100 through the transmission member 20. It should be further noted that the above-mentioned reference plane is Figure 1 and 6 the plane seen from this top-down angle.

[0077] If considered from the perspective of a three-dimensional space and in the actual use state of the product, the reference plane formed by the first direction and the second direction is a horizontal plane. In the horizontal plane, the extending direction of the inclined surface forms an angle with both the first direction and the second direction, and the angle between the inclined surface and the first direction is greater than the angle between the inclined surface and the second direction, so as to facilitate the transmission member 20 to drive the wiper assembly 30 to move.

[0078] In this embodiment, the floor brush further includes a control unit. When the floor brush is in the strong force state, the driving member 10 receives the signal from the control unit to adjust the distance between the wiper assembly 30 and the rotary brush 100. When it is necessary to quickly clean the accumulated water on the ground, the floor brush needs to be in the strong force state. The control unit sends a control signal to control the driving member 10 to shorten the moving distance of the transmission member 20 and the wiper assembly 30, so that the wiper assembly 30 approaches the rapidly rotating rotary brush 100 to achieve rapid drainage of the rotary brush 100.

[0079] Specifically, the control unit includes a start / stop switch, which controls the start and stop of the driving member 10. Optionally, in this embodiment, the roller brush 100 is of a tubular structure. When the control unit controls the wiper assembly 30 to squeeze the roller brush 100, the roller brush 100 deforms to drain the water inside the roller brush 100.

[0080] In this embodiment, the floor brush is configured with a self-cleaning state. The self-cleaning state means that the floor brush is located on an external base station, the roller brush rotates, the liquid distributor sprays water, the wiper assembly approaches or moves away from the roller brush, and the control unit includes a control member and a detection member. The detection member is used to detect the current value for controlling the roller brush 100. The control member is used to control the distance between the wiper assembly 30 and the roller brush 100 according to the detected current value. After the accumulated water on the ground has been cleaned by the floor brush and it is necessary to clean the floor brush for the next use, for the floor brush in the self-cleaning state, the roller brush 100 rotates and the wiper assembly 30 approaches the roller brush 100. During this process, the detection member can detect the current value on the roller brush 100 and transmit the detected current value to the control member. According to the magnitude of the current value detected by the detection member, the control member adjusts the driving state of the driving member 10. If the current value is too large, it indicates that the frictional force between the wiper assembly 30 and the roller brush 100 is too large. At this time, the driving member 10 reversely drives the transmission member 20 to further move the wiper assembly 30 away from the roller brush 100 to prevent the current value on the roller brush 100 from being too large and causing the roller brush 100 to be burned. After receiving the current value, it can automatically adjust the driving state of the driving member 10 to achieve the automatic adjustment between the wiper assembly 30 and the roller brush 100, greatly reducing the complexity of the adjustment and effectively ensuring the cleaning effect, so that the wiper assembly 30 and the roller brush 100 are in reliable contact.

[0081] Specifically, after the detection member measures the magnitude of the current value on the roller brush 100, it compares it with the preset current value in the detection member and transmits the signal to the control member. If the detected current value is less than the preset value, the driving member 10 is controlled to start, and the wiper assembly 30 is controlled to move in the direction approaching the roller brush 100, so as to further squeeze the roller brush 100 and squeeze out the water inside the roller brush 100. If the detected current value is greater than the preset value, the driving member 10 is controlled to stop to prevent the wiper assembly 30 from further squeezing the roller brush 100, avoiding the overload of the current value of the roller brush 100 and further avoiding damage to the wiper assembly 30.

[0082] Optionally, the control unit further includes a pressure sensor. The pressure sensor is signal-connected to the control member and is disposed at the extrusion end of the roller brush 100. When the pressure sensor detects that the pressure value between the wiper assembly 30 and the roller brush 100 is less than the preset value, the control member controls the driving member 10 to start, and the wiper assembly 30 extrudes the roller brush 100; when the pressure sensor detects that the pressure value between the wiper assembly 30 and the roller brush 100 is greater than the preset value, the driving member 10 stops. By adopting the pressure detection method, the extrusion cooperation relationship between the wiper assembly 30 and the roller brush 100 can also be effectively obtained, so as to effectively adjust and control the movement of the wiper assembly 30 and the roller brush 100 from multiple angles of pressure and current detection, thereby ensuring the use reliability of the cleaning device.

[0083] In this embodiment, the floor brush is configured with a dry and flexible state. The dry and flexible state means that the floor brush is located on an external base station, the liquid distributor does not spray liquid, the wiper assembly 30 intermittently approaches or moves away from the roller brush 100, and the base station performs a drying action on the roller brush. The control unit includes a detection member and a control member. The control member controls the wiper assembly 30 to intermittently approach or move away from the roller brush 100 according to the signal obtained by the detection member. After the floor brush completes the ground cleaning and self-cleaning work, if the roller brush 100 is in a wet state and is stored, the roller brush 100 is likely to generate peculiar smell and mildew, which will affect the service life of the roller brush 100 and the user experience. By switching the floor brush to the dry and flexible state, the roller brush 100 keeps rotating, and the control member controls the wiper assembly 30 to intermittently approach or move away from the roller brush 100, and uses the wiper assembly 30 to clean the stains on the surface of the roller brush 100 and squeeze out the water in the roller brush 100, so as to achieve the effect of drying the floor brush.

[0084] Specifically, the control member is a timer. By controlling the periodic forward or reverse rotation of the driving member 10, the periodic drainage of the roller brush 100 is realized to prevent too much sewage in the roller brush 100. Of course, in addition to the above-mentioned self-cleaning mode and drying mode, according to the needs, in a suitable mode, corresponding detection means can be used to collect and judge the movement state and working conditions of the wiper assembly 30 and the roller brush 100, so as to start the wiper assembly 30 to clean the roller brush 100 in a timely manner and be able to adaptively adjust the working conditions of the roller brush 100.

[0085] Such as Figure 6 and Figure 11In the illustrated embodiment, the wiper assembly 30 includes a wiper member 31 and a connecting member 32. The connecting member 32 is connected to the wiper member 31, and the connecting member 32 has a sliding surface. The wiper member 31 is used to abut against the roller brush 100. When the local brush needs to be in multiple different working states to achieve the effects of cleaning the ground, self-cleaning, and drying the roller brush 100, the sliding surface of the transmission member 20 cooperates with the sliding surface of the connecting member 32, and the sliding surface on the transmission member 20 squeezes the sliding surface on the connecting member 32 to drive the wiper member 31 to squeeze the roller brush 100.

[0086] Compared with Figure 1 the wiper assembly 30 with only "one cross plate" shown, the separable wiper member 31 and connecting member 32 have a better adjustable effect. That is, there is a certain floating space between the two, thus providing a buffer space for the movement of the roller brush 100.

[0087] Specifically, the sliding surface is provided on the side of the connecting member 32 opposite to the transmission member 20.

[0088] In this embodiment, the connecting member 32 is fixedly arranged on the wiper member 31 or at least a part of the connecting member 32 can move relative to the wiper member 31. During the long-term cleaning process of the local brush, the wiper assembly 30 repeatedly approaches the roller brush 100. When the connecting member 32 is fixedly arranged on the wiper member 31, rapid transmission can be achieved and it is convenient for assembly. And when at least a part of the connecting member 32 moves relative to the wiper member 31, a soft contact between the wiper member 31 and the roller brush 100 can be realized. Reasonably select the connection method of the suitable wiper member 31 and the connecting member 32 according to actual needs.

[0089] Specifically, when the connecting member 32 is fixedly arranged on the wiper member 31, the connecting member 32 is connected to the wiper member 31 by screws or integrally formed. In this case, the above-mentioned buffer space and floating space do not exist. However, because the two are two independent structures arranged together, suitable materials can be selected according to the situations of the two, so as to ensure that each part of the structure has the characteristics it should have. Of course, if the independent connecting member 32 and the wiper member 31 have been set, the form of fixedly connecting the two is usually not selected for installation.

[0090] In another embodiment of the present application, as Figures 8 to 10As shown, the connecting member 32 includes a first connecting member 321 and a second connecting member 322 that can move relative to each other. The first connecting member 321 has a sliding surface, and the second connecting member 322 is fixed to the wiper member 31. By providing a sliding surface on the first connecting member 321, the first connecting member 321 is squeezed by the transmission member 20 to realize the relative movement of the first connecting member 321 and the second connecting member 322, and then the wiper member 31 squeezes the roller brush 100. The first connecting member 321 and the second connecting member 322 that can move relative to each other provide more movement space when being squeezed and cooperating with the roller brush 100, avoiding the excessive reaction force provided by the roller brush 100 from being rigidly transmitted to the wiper assembly 30 and the transmission member 20, effectively avoiding the problems of mechanical jamming or short-term overload, and effectively ensuring the movement reliability of the wiper assembly 30.

[0091] Specifically, a sliding surface is provided at the bottom of the first connecting member 321, and the sliding surface is a concave portion 40. A convex portion 50 is provided on the transmission member, and the convex portion 50 is located at the top of the transmission member 20. By the sliding of the convex portion 50 in the concave portion 40, the transmission member 20 drives the first connecting member 321 to move in the second direction. Here, the cooperation relationship between the concave portion and the convex portion has the aforementioned beneficial effects, so it will not be elaborated here.

[0092] In this embodiment, both the first connecting member 321 and the second connecting member 322 can move in the second direction. By providing a sliding surface on the first connecting member 321, the first connecting member 321 is squeezed by the transmission member 20 to realize the relative movement of the first connecting member 321 and the second connecting member 322, and then the wiper member 31 squeezes the roller brush 100. When there is accumulated water on the ground, the floor brush starts, the roller brush 100 rotates to clean the accumulated water, the transmission member 20 squeezes the first connecting member 321 through the sliding surface, the first connecting member 321 approaches the second connecting member 322 in the second direction and then drives the wiper member 31 to approach the roller brush 100. By the way that both the first connecting member 321 and the second connecting member 322 move in the second direction, the transmission member 20 drives the first connecting member 321 and the second connecting member 322 to move successively along the second direction, realizing the friction force transition between the roller brush 100 and the wiper member 31. Since both of them can move in the second direction, the movement directions of the two are consistent with the directions of the forces acting on the roller brush 100, so that the force transmission is more direct and avoids loss. At the same time, in the second direction, the reaction force exerted by the roller brush 100 on the wiper assembly 30 plays a role of floating pressure relief to a certain extent, avoiding the problems of mechanical jamming or short-term overload.

[0093] Specifically, when the transmission member 20 moves in the first direction, it drives the first connecting member 321 to move and then drives the second connecting member 322 to approach the roller brush 100 along the second direction.

[0094] In this embodiment, the first connecting member 321 and the second connecting member 322 are hooked and matched so that when the wiper assembly 30 moves away from the roller brush 100, the first connecting member 321 pulls the second connecting member 322 and the wiper member 31. Through the hooking and matching method, the movement of the second connecting member 322 is driven by the first connecting member 321. When the floor brush needs to be stored after the cleaning work is completed, the floor brush is in a dry and flexible state. The wiper assembly 30 periodically approaches or moves away from the roller brush 100. When the transmission member 20 drives the first connecting member 321 away from the roller brush 100, since the first connecting member 321 and the second connecting member 322 are hooked and matched, the second connecting member 322 is pulled away from the roller brush 100, and finally the wiper member 31 moves away from the roller brush 100, ending the squeezing and cleaning of the roller brush 100. That is to say, by adopting the hooking and matching method, the force can be transmitted effectively in a single direction, while in the opposite direction, there is only a guiding effect, and the force will not be directly transmitted without loss. Of course, if a direct force transmission in both forward and reverse directions is desired, then the first connecting member 321 and the second connecting member 322 are connected in a way that keeps their relative positions fixed all the time, and they are "rigidly connected" and cannot achieve the effect of "floating connection". In this embodiment, especially Figure 5 in the embodiment shown, the "floating connection" method is adopted.

[0095] As Figures 9 to 11 shown, the second connecting member 322 has a limit hook 70, and a hanging groove 324 adapted to the limit hook 70 is provided on the first connecting member 321. By opening the hanging groove 324 on the first connecting member 321, the limit hook 70 on the second connecting member 322 realizes the hooking and matching between the first connecting member 321 and the second connecting member 322. In the dry and flexible state, the wiper assembly 30 periodically moves away from the roller brush 100. The driving member 10 drives the first connecting member 321 away through the transmission member 20. At this time, the first connecting member 321 and the second connecting member 322 are relatively close, and the movement of the first connecting member 321 will not drive the second connecting member 322 and the wiper member 31 to move until the wall of the hanging groove 324 abuts against the limit hook 70. After the abutment, the first connecting member 321 drives the second connecting member 322 to move to realize the wiper member 31 moving away from the roller brush 100. As mentioned before, if the limit hook 70 and the hanging groove 324 here are fixed in a snap-locking manner, then the first connecting member 321 and the second connecting member 322 are snap-connected and fixed and will not move relative to each other. Therefore, in this embodiment, the limit hook 70 and the hanging groove 324 mentioned are a matching relationship in which the limit hook 70 can move relative to the hanging groove 324 and the two can move synchronously after the limit hook 70 moves to contact and stop against the wall surface of the hanging groove 324.

[0096] Specifically, the limit hook 70 is integrally formed with the second connecting member 322, and the depth of the hanging groove 324 is adapted to the hook portion of the limit hook 70. Optionally, the limit hook 70 is provided on the first connecting member 321, and the hanging groove 324 is provided on the second connecting member 322. Of course, it is not limited to providing the limit hook 70 on the first connecting member 321. The limit hook 70 and the hanging groove 324 can also be interchanged, mainly to ensure that the movement of the wiper assembly 30 can be controlled during the process of pulling the wiper assembly 30 backward.

[0097] As Figures 8 to 11 shown, the wiper assembly 30 further includes an elastic member 80. The elastic member 80 is disposed between the first connecting member 321 and the second connecting member 322 to enable the floating connection between the first connecting member 321 and the second connecting member 322. When the floor brush starts to clean, self-clean, or dry the roller brush 100, after the first connecting member 321 is squeezed by the transmission member 20, one end of the elastic member 80 is squeezed by the first connecting member 321, and the other end of the elastic member 80 abuts against the second connecting member 322. After the elastic member 80 is compressed, the elastic force of the elastic member 80 drives the second connecting member 322 to move, realizing the elastic connection between the first connecting member 321 and the second connecting member 322 and having a floating movement space, providing a temporary buffer for the rapid extrusion of the roller brush 100 and ensuring the movement reliability of the wiper assembly 30.

[0098] Specifically, connecting columns 323 are provided on both the first connecting member 321 and the second connecting member 322. The elastic member 80 is disposed on the connecting columns 323. The elastic member 80 is a spring. Through the elastic member 80, the force on the first connecting member 321 can be transmitted to the second connecting member 322. When the transmission member 20 is reset, the sliding surface on the transmission member 20 no longer squeezes the sliding surface on the first connecting member 321. The setting of the elastic member 80 facilitates the first connecting member 321 to move away from the roller brush 100. The connecting columns 323 can effectively guide and position the elastic member 80, avoiding the failure caused by excessive deformation when the elastic member 80 is compressed, and at the same time improving the contact support of the wiper assembly 30 for the roller brush 100.

[0099] As Figures 4 to 5 、 Figures 9 to 11 shown, a gear structure 11 is provided at the output end of the driving member 10, and a rack structure 21 is provided on the transmission member 20. The rack structure 21 meshes with the gear structure 11, and the extending direction of the rack structure 21 is parallel to the first direction. After the floor brush is started, the output end of the driving member 10 rotates, and through the cooperation of the gear and the rack, the rotation of the output end of the driving member 10 is converted into the movement of the transmission member 20 along the first direction, and then the wiper assembly is moved along the second direction through the sliding surface, realizing the wiper assembly to scrape the roller brush.

[0100] Specifically, the driving member 10 converts its own rotation into the movement of the transmission member 20 in the first direction through the gear structure 11. The rack structure 21 is integrally formed with or detachably connected to the transmission member 20. Of course, in addition to the gear-rack cooperation form here, the above-mentioned motion relationship can also be achieved through the cooperation of a disc and a pulley.

[0101] In this embodiment, when the floor brush performs a cleaning action, it can suck the dirt on the surface to be cleaned into the sewage tank. When the cleaning device cleans the ground, the floor brush sucks the dirt into the sewage tank to prevent the sewage from remaining in the body or flowing onto the ground and reducing the use effect of the cleaning device.

[0102] Specifically, the cleaning device is a sweeper, such as Figures 1 to 2 and Figure 6 As shown, the housing 90 is further provided with rollers 110. The sweeper moves through the rollers 110. The housing 90 is further provided with a water spraying assembly 60. The water spraying assembly 60 sprays a cleaning agent and water onto the rotary brush 100 to assist the sweeper in cleaning the ground.

[0103] The utility model has the following beneficial effects:

[0104] Through the above-mentioned floor brush, the water scraping assembly 30 can be controlled to move towards the rotary brush 100 according to requirements, so that the floor brush forms a strong state. In the strong state, the rotary brush 100 is in a rotating state, the body is tilted, the main motor sucks, and the water scraping assembly 30 moves and approaches the rotary brush 100. In this way, the contact between the water scraping assembly 30 and the rotary brush 100 can be made closer, and more water on the rotary brush 100 can be scraped off, so that the water absorption capacity of the rotary brush 100 is stronger.

[0105] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
