[0002] Dust collectors, floor washing machines, and sweeping robots are commonly used cleaning equipment in families. Many cleaning equipment has multiple functions such as dust collection and floor mopping.
[0003] In related technologies, cleaning equipment with dust collection and floor mopping functions usually uses a floor brush to clean the floor. The floor brush is provided with a rolling brush and a water tank. The water tank can supply cleaning water to wet the rolling brush. The wet rolling brush is rolled on the floor to achieve the effect of wet mopping. In addition, a suction port is arranged on the floor brush. The suction port can suck up garbage and debris on the floor and sewage scraped off from the rolling brush.
[0004] However, after the cleaning equipment completes cleaning, water stains are left on the rolling brush of the floor brush, which causes the floor brush to easily produce odor. CONTENT OF THE UTILITY MODEL
[0005] The present application provides a floor brush device and a cleaning equipment to solve the technical problem that water stains are left on the rolling brush of the floor brush after cleaning, which causes the floor brush to easily produce odor.

The floor brush device comprises a device main body, a water scraping assembly, a water separating assembly, and a water spraying assembly. The device main body has a floor brush air duct. The water scraping assembly, the water separating assembly, and the water spraying assembly are arranged on the device main body.
[0007] The water separating assembly is located on the front side of the water scraping assembly along the cleaning direction of the floor brush device. The water separating assembly and the water scraping assembly have a gap therebetween. The gap is in communication with the floor brush air duct. An end of the gap towards the lower side of the device main body forms a first suction port. The water spraying assembly is configured to supply water to the area below the floor brush device towards which the first suction port is directed.
[0008] The floor brush device provided by the present application forms a first suction port through the gap between the water scraping assembly and the water separating assembly. The first suction port has a flat structure. The water spraying assembly can spray water to wet the cleaning surface opposite to the first suction port. A large negative pressure suction force is formed by the flat first suction port. The water wetting the cleaning surface can be sucked into the floor brush air duct. Dust and stains are removed from the cleaning surface during the process of the cleaning water being sucked into the first suction port, which achieves good cleaning effect. In this way, the rolling brush is cancelled. Sewage is not left on the floor brush device, which avoids odor generated when the floor brush device is placed after cleaning.
[0009] As an optional implementation, the gap extends along the width direction of the floor brush device.
[0010] In this way, the gap can form an elongated first suction port, and the effective suction area of the first suction port covers each position in the width direction of the floor brush device.

[0019] As an optional embodiment, at least one of the first scraping member and the flexible member is provided with a protruding portion towards the side of the other, and the protruding portion abuts between the flexible member and the first scraping member to maintain the gap when the first suction port generates a negative pressure suction force.
[0020] In this way, the first scraping member and the flexible member are prevented from closing the first suction port under the action of the negative pressure suction force, thereby ensuring the smoothness of the air flow.
[0021] As an optional implementation, the width dimension of the protruding portion towards the outside end of the first suction port is greater than the width dimension of the protruding portion towards the inside end of the first suction port.
[0022] In this way, the loss of airflow during the inflow into the first suction port can be reduced.
[0023] As an optional implementation, the side wall of the width of the protruding portion towards the outside end of the first suction port is arc-shaped.
[0024] In this way, the airflow inhaled into the first suction port can be guided, and the smoothness of the airflow can be improved.

[0035] As an optional embodiment, the floor brush device has a second suction port, which is in communication with the floor brush air duct and located at the front side of the first suction port along the cleaning direction of the floor brush device.
[0036] In this way, large-volume garbage and sundries can be sucked into the floor brush air duct through the second suction port first, and then the remaining stubborn dust and stains can be cleaned by wetting the surface to be cleaned, so that the cleaning effect is improved.

[0055] The terms "first", "second", "third" (if any) in the specification and claims of the application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein.
[0056] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or maintenance tool including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.
[0057] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme in the embodiments of the application will be described clearly and completely in the following with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.
[0058] The cleaning device with dust collection and mopping function usually uses a floor brush to clean the floor, a roller brush and a water tank are arranged on the floor brush, the water tank can supply cleaning water to wet the roller brush, and the wet roller brush rolls on the floor to achieve the effect of wet mopping. A suction port is usually arranged on the floor brush, which can suck the garbage and sundries on the floor and the sewage scraped off from the roller brush.
[0059] However, in current cleaning equipment, the roller brush on the floor brush is usually wrapped with a cleaning component that easily absorbs water. During the cleaning process, the cleaning component is squeezed by the scraper to remove the absorbed sewage. However, the water cannot be completely removed. After cleaning is completed, water stains will remain on the roller brush. If the cleaning component on the roller brush is not removed and dried in time, the floor brush is prone to odor or even mold.
[0060] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The roller brush structure on the floor brush is eliminated. Through structural design of the suction port, the suction port is narrower and generates greater suction power. During cleaning, cleaning water is sprayed or dripped onto the area facing the suction port. The suction power of the suction port draws in the wastewater from the surface to be cleaned. Thus, as the cleaning water enters the suction port from the surface to be cleaned, it removes dust and stains, improving cleaning efficiency. Furthermore, no drying is required after cleaning, and no odor is generated.
[0061] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.
[0062] The floor brush device provided in this application embodiment is applied in cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean various types of floors and other surfaces. This application embodiment does not make any specific limitations in this regard.
[0063] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 3 for Figure 2 A partial view of position A in the middle.
[0064] See Figures 1 to 3 As shown, this application provides a floor brush device 100, which includes a device body 110, a squeegee assembly 120, a water-blocking assembly 130, and a water-spraying assembly 140. The squeegee assembly 120, the water-blocking assembly 130, and the water-spraying assembly 140 are all disposed on the device body 110. The device body 110 can move along the surface to be cleaned, the water-spraying assembly 140 can wet the surface to be cleaned, the water-blocking assembly 130 is used to isolate the squeegee assembly 120 and the water-spraying assembly 140, and the squeegee assembly 120 can scrape away water stains from the wetted surface.
[0065] The water-proof assembly 130 is located in front of the water scraping assembly 120 along the cleaning direction of the floor brush device 100. The water-proof assembly 130 and the water scraping assembly 120 have a gap 101 therebetween, and the gap 101 forms a first suction port 102 at one end below the device body 110. The device body 110 has a floor brush air duct 111, and the gap 101 is in communication with the floor brush air duct 111.
[0066] It can be understood that the first suction port 102 is directed to the surface to be cleaned below the device body 110, and the water spraying assembly 140 can supply water to the area below the floor brush device 100 directed by the first suction port 102. After the water sprayed by the water spraying assembly 140 wets the surface to be cleaned, the negative pressure generated by the first suction port 102 can suck the sewage on the surface to be cleaned into the floor brush air duct 111.
[0067] Since the water-proof assembly 130 and the water scraping assembly 120 are arranged in front of and behind the floor brush device 100 respectively, the water sprayed by the water spraying assembly 140 can wet the surface to be cleaned in the area directly below and adjacent to the first suction port 102. In the process of sucking the cleaning water on the surface to be cleaned into the first suction port 102, the water flow passing through the surface to be cleaned can carry away dust and stains.
[0068] It should be noted that in the floor brush device 100 provided by the embodiment of the present application, the first suction port 102 is formed through the gap 101 between the water scraping assembly 120 and the water-proof assembly 130, so that the first suction port 102 has a flat structure. When the air is sucked in the floor brush air duct 111, the first suction port 102 can form a larger negative pressure to ensure that the water wetting the surface to be cleaned is sucked into the first suction port 102.
[0069] Compared with the prior art, the floor brush device 100 in the embodiment of the present application does not need to use a roller brush. In the process of sucking the cleaning water passing through the surface to be cleaned into the first suction port 102, dust and stains can be carried away, thereby achieving good cleaning effect. In this way, the sewage will not be left on the floor brush device 100, and the floor brush device 100 will not produce odor when it is placed after cleaning.
[0070] Figure 4 A structure diagram of the water scraping assembly in the floor brush device provided by the embodiment of the present application is shown in FIG. 2; Figure 5 A structure diagram of the water-proof assembly in the floor brush device provided by the embodiment of the present application is shown in FIG. 3; Figure 6 A structure diagram of the water spraying assembly in the floor brush device provided by the embodiment of the present application is shown in FIG. 4; Figure 7 A connection diagram of the water scraping assembly, the water-proof assembly and the water spraying assembly in the floor brush device provided by the embodiment of the present application is shown in FIG. 5; Figure 8 A structure diagram of the water scraping assembly in the floor brush device provided by the embodiment of the present application is shown in FIG. 2; Figure 7 A partial view of position B in FIG. 2.
[0071] The moving direction of the floor brush device 100 during cleaning is defined as the X direction, and the width direction of the floor brush device 100 is the Y direction, which is perpendicular to the X direction.
[0072] Please refer to Figures 1 to 8 In some embodiments, the gap 101 extends along the width direction of the floor brush device 100. In this way, the height dimension of the gap 101 is small and the length dimension is large, so that the gap 101 can form an elongated first suction port 102, and the effective suction area of the first suction port 102 covers various positions in the width direction of the floor brush device 100.
[0073] It can be understood that the gap 101 extends along the Y direction, the first suction port 102 extends along the Y direction, and the length of the gap 101 forming one end of the first suction port 102 can be as much as or slightly less than the width of the floor brush device 100, so as to maximize the effective negative pressure suction area of the first suction port 102.
[0074] In some embodiments, the height dimension of the gap 101 gradually increases along the airflow suction direction of the first suction port 102, so as to ensure that the first suction port 102 has a large negative pressure suction force, and at the same time, the airflow has a large flow cross section when entering the floor brush air duct 111, thereby improving the airflow flow and smoothness.
[0075] It should be noted that in the case of stable airflow flow, the narrow spacing between the upper side and the lower side of the first suction port 102 can increase the flow rate of the airflow entering the first suction port 102. The higher the airflow flow rate, the greater the pressure difference between the area facing the first suction port 102 and the external environment, thereby generating a larger negative pressure. A larger negative pressure can suck the cleaning water on the surface to be cleaned, and can avoid water stains from adhering to the surface to be cleaned.
[0076] In addition, during the process of the first suction port 102 sucking the cleaning water on the surface to be cleaned, the cleaning water will flow along the surface to be cleaned and flow to the first suction port 102, so that it is easier to remove stubborn stains and dust attached to the surface to be cleaned, and has better cleaning effect.
[0077] In some embodiments, the height of the gap 101 at the first suction port 102 is greater than or equal to 0.5 mm and less than or equal to 2 mm, so as to control the height dimension of the gap 101 within a reasonable range and have a good cleaning effect.
[0078] It can be understood that maintaining the height of the gap 101 within a reasonable range can control the height dimension of the first suction port 102 within a reasonable range. On the one hand, it avoids that the first suction port 102 is too narrow to suck some solid particles and sundries, and on the other hand, it avoids that the first suction port 102 is too wide to generate a large enough suction force to suck the cleaning water.
[0079] Exemplarily, the height dimension of the first suction port 102 can include, but is not limited to, 0.5 mm, 0.6 mm, 1 mm, 1.5 mm, 1.9 mm, 2 mm, etc., and the present embodiment is not limited thereto. The height direction of the first suction port 102 is perpendicular to the air flow suction direction of the first suction port 102 and perpendicular to the extension direction of the first suction port 102.
[0080] The specific structure of the wiper assembly 120 and the water isolation assembly 130 will be described in detail below.
[0081] Please refer to Figures 1 to 8 In a possible implementation, the wiper assembly 120 can include a wiper plate 122 and a first scraping member 121. The water isolation assembly 130 can include a water isolation plate 132 and a flexible member 131, and the water isolation plate 132 is connected to the wiper plate 122. The first scraping member 121 is connected to the lower edge of the wiper plate 122, the flexible member 131 is connected to the lower edge of the water isolation plate 132, and the first scraping member 121 and the flexible member 131 form the first suction port 102.
[0082] It can be understood that the wiper plate 122 and the water isolation plate 132 form a channel for air flow suction, the first scraping member 121 and the flexible member 131 have a gap 101 to form the first suction port 102, and the sewage and air flow sucked by the first suction port 102 can enter the brush air duct 111 through the channel between the water isolation plate 132 and the wiper plate 122.
[0083] It should be noted that during the cleaning and sewage suction process of the brush device 100, the first scraping member 121 can scrape the surface to be cleaned to avoid sewage residue. The flexible member 131 has a certain distance from the surface to be cleaned to ensure that the first suction port 102 is open to the front side of the cleaning direction of the brush device 100, and the sewage on the surface to be cleaned can be sucked into the first suction port 102 from the front side of the first suction port 102.
[0084] Exemplarily, the first scraping member 121 can be made of elastic materials such as rubber and silicone. The first scraping member 121 can have a strip structure, and the length of the first scraping member 121 can be equal to or close to the length of the wiper plate 122. The first scraping member 121 and the wiper plate 122 can be bonded by glue, or the first scraping member 121 and the wiper plate 122 can be fixedly connected by a fastener such as a buckle, or the first scraping member 121 and the wiper plate 122 can be integrally formed by overmolding, and the present embodiment is not limited thereto.
[0085] Exemplarily, the flexible piece 131 can be made of rubber, silica gel or other elastic materials. The flexible piece 131 can have a strip-shaped structure, and the length of the flexible piece 131 can be equal to or close to the length of the waterproof plate 132. The flexible piece 131 and the waterproof plate 132 can be bonded by glue, or the flexible piece 131 and the waterproof plate 132 can be fixedly connected by a fastener such as a buckle, or the flexible piece 131 and the waterproof plate 132 can be integrally formed by overmolding, and the embodiments of the present application do not make specific limitations in this regard.
[0086] It should be noted that the first scraping piece 121 and the flexible piece 131 can be arranged in parallel to each other, and the lengths of the two can be equal or close to each other, so as to ensure that the length of the first suction port 102 formed by the two is as close as possible to the width of the floor cleaning device 100.
[0087] In some embodiments, the first scraping piece 121 is arranged to be inclined to the front side of the device body 110 relative to the vertical direction, and the flexible piece 131 is arranged to be inclined to the front side of the device body 110 relative to the vertical direction.
[0088] It can be understood that when the lower edge of the first scraping piece 121 is in contact with the surface to be cleaned, the lower edge of the flexible piece 131 has a spacing from the surface to be cleaned, so that the first suction port 102 can be inclined to the front side of the cleaning direction of the floor cleaning device 100, and the first suction port 102 can suck in the sewage in the direction of the floor cleaning device 100, having a higher sewage suction efficiency.
[0089] Exemplarily, the inclination angle of the first scraping piece 121 relative to the vertical direction is 5°, 10°, 30°, 45°, 60°, 80°, 85°, etc., and the embodiments of the present application do not make specific limitations in this regard. In addition, the first scraping piece 121 can have a certain interference amount when in contact with the surface to be cleaned, that is, the first scraping piece 121 abuts against the surface to be cleaned to produce a certain degree of elastic deformation.
[0090] In some embodiments, at least one of the first scraping piece 121 and the flexible piece 131 is provided with a protruding portion 123 towards the side of the other, and when the first suction port 102 generates a negative pressure suction force, the protruding portion 123 abuts between the flexible piece 131 and the first scraping piece 121 to maintain the gap 101, so as to avoid that the first scraping piece 121 and the flexible piece 131 close the first suction port 102 under the action of the negative pressure suction force, thereby ensuring the smoothness of the airflow.
[0091] It can be understood that due to the fact that the air pressure in the first suction port 102 is less than the external annular atmospheric pressure, the first scraping piece 121 and the flexible piece 131 will have a tendency to approach each other under the action of the internal and external pressure difference. The protruding portion 123 can maintain the first suction port 102 in an open state.
[0092] Exemplarily, the protruding portion 123 can be integrally formed with the first scraping member 121, and the protruding portion 123 protrudes from the surface of the first scraping member 121 towards the flexible member 131.
[0093] In some embodiments, the width of the protruding portion 123 towards the outer end of the first suction port 102 is greater than the width of the protruding portion 123 towards the inner end of the first suction port 102, so that the loss of airflow during the inflow of the first suction port 102 can be reduced.
[0094] It can be understood that the side wall of the width of the protruding portion 123 towards the outer end of the first suction port 102 is arc-shaped, so that the airflow inhaled into the first suction port 102 can be guided and the smoothness of the airflow can be improved.
[0095] Exemplarily, the protruding portion 123 can be in the shape of a water droplet.
[0096] Exemplarily, the protruding portion 123 can be multiple, and the multiple protruding portions 123 are arranged at intervals along the length direction of the first scraping member 121, so that the positions of the first suction port 102 in the length direction can be supported and the smoothness of the airflow can be ensured.
[0097] It should be noted that the number of the protruding portion 123 can be two, three, four or more, and the number of the protruding portion 123 and the specific interval between adjacent protruding portions 123 are not limited in the embodiments of the present application.
[0098] In some embodiments, the air outlet 124 is located at the end of the wiper assembly 120 away from the first suction port 102, and the air outlet 124 is connected to the gap 101 and the brush air duct 111, and the gap 101 is provided with a flow guide structure 103 opposite to the air outlet 124.
[0099] It can be understood that when the airflow entering the gap 101 flows back at the air outlet 124, the flow guide structure 103 can guide the airflow to avoid the airflow from being mixed, and the loss of the airflow can be reduced.
[0100] Exemplarily, the air outlet 124 can be located at the middle position of the length direction of the wiper assembly 120, and when the airflow and the sewage are inhaled by the first suction port 102, the airflow and the sewage will flow to the middle air outlet 124 after entering the space between the wiper plate 122 and the water barrier plate 132, and the airflow and the sewage collected on both sides of the air outlet 124 can flow into the air outlet 124 under the guidance of the flow guide structure 103.
[0101] In some embodiments, the flow guide structure 103 can include a first flow guide portion 1031 connected with the wiper assembly 120 and a second flow guide portion 1032 connected with the water barrier assembly 130. The first flow guide portion 1031 is opposite to and abuts against the second flow guide portion 1032. In this way, the flow guide structure 103 can be formed when the wiper assembly 120 and the water barrier assembly 130 are assembled, ensuring that the lower and upper ends of the flow guide structure 103 can be supported at the bottom and top of the gap 101.
[0102] For example, the first flow guide portion 1031 and the second flow guide portion 1032 can have a shape matching each other, and both can have a shape of a water droplet. When the water barrier plate 132 and the wiper plate 122 are abutted, the first flow guide portion 1031 and the second flow guide portion 1032 can abut against each other in a normal direction.
[0103] For example, the first flow guide portion 1031 can be integrally formed with the wiper plate 122. The second flow guide portion 1032 can be integrally formed with the water barrier plate 132.
[0104] In some embodiments, the water spraying assembly 140 is connected to the water barrier assembly 130 on a side away from the wiper assembly 120, the water barrier assembly 130 has a flow guide surface 133 facing the water spraying assembly 140, the water spraying assembly 140 is configured to spray water to the flow guide surface 133, and the flow guide surface 133 guides and drops the cleaning water to the surface to be cleaned, so that the water flow can continuously and stably wet the surface to be cleaned, avoiding too much or too little water flow.
[0105] For example, the water spraying assembly 140 can be connected to the water barrier assembly 130 by a bolt fastener. Alternatively, the water spraying assembly 140 can be welded to the water barrier plate 132.
[0106] In some embodiments, the floor brush device 100 can further include a second scraping member 141 connected to a lower edge of the water spraying assembly 140 and located on a front side of the water barrier assembly 130 along the cleaning direction of the floor brush device 100.
[0107] It can be understood that the second scraping member 141 is spaced apart from the wiper assembly 120, and a relatively closed space can be formed between the wiper assembly 120 and the second scraping member 141. When the first suction port 102 sucks in the air flow, a negative pressure area is formed between the wiper assembly 120 and the second scraping member 141, thereby improving the negative pressure suction force of the first suction port 102.
[0108] For example, the second scraping member 141 and the first scraping member 121 form a cleaning cavity 104 in communication with the first suction port 102, and the water spraying assembly 140 is configured to supply water to the cleaning cavity 104.
[0109] It can be understood that the second scraping member 141 is located in front of the first scraping member 121 in the cleaning direction of the floor brush device 100, the cleaning cavity 104 is the area between the first scraping member 121 and the second scraping member 141, the first suction port 102 is in communication with the cleaning cavity 104, when the first suction port 102 generates a negative pressure suction, a negative pressure state is formed in the cleaning cavity 104, therefore, the water sprayed by the water spraying assembly 140 into the cleaning cavity 104 will flow to the first suction port 102 along the surface to be cleaned which is opposite to the cleaning cavity 104, and be sucked into the first suction port 102.
[0110] In some embodiments, the water isolation assembly 130 is located between the first scraping member 121 and the second scraping member 141 towards the end below the device body 110. The end of the water isolation assembly 130 towards the end below the device body 110 is higher than the lower edges of the first scraping member 121 and the second scraping member 141.
[0111] It can be understood that when the lower edge of the first scraping member 121 is in contact with the surface to be cleaned, the lower edge of the flexible member 131 has a spacing with the surface to be cleaned, the water sprayed on the surface to be cleaned can pass through the lower edge of the water isolation assembly 130 and enter the inside of the first suction port 102, ensuring that the cleaning water passes through the surface to be cleaned during being sucked into the first suction port 102, having a good cleaning effect.
[0112] For example, the lower edges of the first scraping member 121 and the second scraping member 141 are arranged in a flush manner. During the cleaning process, it can be ensured that the first scraping member 121 and the second scraping member 141 are in contact with the surface to be cleaned at the same time, ensuring that the cleaning cavity 104 is relatively closed in the cleaning direction, and the first suction port 102 can form a larger negative pressure suction.
[0113] In some embodiments, the first scraping member 121 and the flexible member 131 have a first side air inlet 1041 between the two ends in the width direction of the floor brush device 100, the first side air inlet 1041 is in communication with the cleaning cavity 104, so that air can also enter from the two sides of the cleaning cavity 104, so that the sewage on the surface to be cleaned converges to the middle, and is more easily sucked into the floor brush air duct 111 from the first suction port 102.
[0114] In some embodiments, the second scraping member 141 and the flexible member 131 have a second side air inlet 1042 between the two ends in the width direction of the floor brush device 100, the second side air inlet 1042 is in communication with the cleaning cavity 104, so that air can also enter from the two sides of the cleaning cavity 104, so that the sewage on the surface to be cleaned converges to the middle, and is more easily sucked into the floor brush air duct 111 from the first suction port 102.
[0115] The structure and arrangement of the water spraying assembly 140 will be described in detail below.
[0116] Please refer to Figures 1 to 8In some embodiments, the water spraying assembly 140 and the water barrier assembly 130 form a water spraying cavity 142 therebetween, and the water spraying cavity 142 is in communication with the cleaning cavity 104.
[0117] When the first scraping member 121 and the second scraping member 141 are in contact with the surface to be cleaned, the lower edge of the water barrier assembly 130 has a spacing from the surface to be cleaned, so that the water in the water spraying cavity 142 enters the cleaning cavity 104 and is sucked into the first suction port 102 through the lower edge of the water barrier assembly 130.
[0118] It can be understood that the water sprayed by the water spraying assembly 140 can first pass through the water spraying cavity 142 and then drop to the surface to be cleaned, and before being sucked into the first suction port 102, the cleaning water first contacts the surface to be cleaned and carries away dust and stains, achieving a better cleaning effect.
[0119] In some embodiments, the water spraying cavity 142 is located above the cleaning cavity 104, and the side of the water barrier assembly 130 facing the water spraying assembly 140 has a flow guide surface 133 extending vertically to guide the water sprayed by the water spraying assembly 140 to the cleaning cavity 104, so that the cleaning water can continuously and smoothly drop to the surface to be cleaned by gravity.
[0120] In one possible implementation, the water spraying assembly 140 is connected to the side of the water barrier assembly 130 away from the water scraping assembly 120 and forms the water spraying cavity 142 with the water barrier assembly 130, and the water spraying cavity 142 is arranged adjacent to the first suction port 102, and the water spraying assembly 140 is configured to spray water into the water spraying cavity 142. The water spraying cavity 142 has a water outlet 1421 facing downward of the device main body 110.
[0121] It can be understood that the cleaning water sprayed into the water spraying cavity 142 can flow to the surface to be cleaned from the water outlet 1421, and since the water outlet 1421 is arranged adjacent to the first suction port 102, the negative pressure suction force generated by the first suction port 102 can suck the water on the surface to be cleaned into the brush air duct 111.
[0122] In some embodiments, the cavity wall of the water spraying cavity 142 is provided with an air inlet 1422, and the air inlet 1422 is in communication with the inside and outside of the water spraying cavity 142.
[0123] It can be understood that since the water spraying cavity 142 is in communication with the first suction port 102 in space, the negative pressure generated by the first suction port 102 can cause the air inlet 1422 to flow into the airflow, and the airflow can flow out of the water outlet 1421, and in this process, the airflow can drive the water in the water spraying cavity 142 to flow to the surface to be cleaned.
[0124] In some embodiments, the air inlet 1422 is located at the top end of the water spraying cavity 142. When the water in the water spraying cavity 142 drips down to the surface to be cleaned by gravity, the air inlet 1422 can be in the same direction as the water flow in the water spraying cavity 142, improving the efficiency of the water flow.
[0125] For example, the air inlet 1422 can be multiple, and the multiple air inlets 1422 are arranged along the length direction of the water spraying cavity 142, so that the water flow at each position in the width direction of the water spraying cavity 142 can be accelerated by the air flow, ensuring the uniformity of the water dripping at different positions in the width direction of the cleaning device.
[0126] In some embodiments, the water spraying assembly 140 can include a water spraying shell 143 and a water spraying cover plate 144, and the water spraying shell 143 is connected with the water isolation assembly 130. The water spraying cover plate 144 is connected to the side of the water spraying shell 143 away from the water isolation assembly 130 and forms a water spraying flow channel 146. The side of the water spraying shell 143 facing the water isolation assembly 130 is provided with a water spraying hole 145, and the water spraying hole 145 is in communication with the water spraying flow channel 146, so as to ensure that the water in the water spraying cavity 142 flows along the surface of the water isolation assembly 130 and drips down, avoiding water splashing or overflowing.
[0127] For example, the water spraying hole 145 can be multiple, and the multiple water spraying holes 145 are arranged along the length direction of the water spraying cavity 142, so that the water supply at each position in the width direction of the device body 110 is uniform.
[0128] In a possible implementation, the floor brush device 100 has a second suction port 105, which is in communication with the floor brush air duct 111, and the second suction port 105 is located on the front side of the first suction port 102 along the cleaning direction of the floor brush device 100.
[0129] It can be understood that during the advancement of the floor brush device 100, the bulk garbage and sundries can be first sucked into the floor brush air duct 111 through the second suction port 105, and then the remaining stubborn dust and stains can be sucked into the first suction port 102 by wetting the surface to be cleaned, improving the cleaning effect.
[0130] For example, the floor brush device 100 is provided with an air duct shell forming the floor brush air duct 111, and the second suction port 105 can be arranged at the front end of the air duct shell. The water scraping assembly 120 can be connected to the rear end of the air duct shell, and the air outlet 124 on the water scraping assembly 120 is in communication with the rear end of the air duct shell, so that the air flow and garbage sucked into the second suction port 105 and the air flow and sewage sucked into the first suction port 102 are collected in the thickness of the air duct shell and then enter the sewage collection cavity of the cleaning equipment 10 together.
[0131] It should be noted that the second suction port 105 has a certain spacing with the first suction port 102, and the second scraping piece 141 is arranged between the first suction port 102 and the second suction port 105.
[0132] Please refer to Figures 1 to 8 The cleaning equipment 10 provided by the embodiment of the present application comprises a device main body 200 and the floor brush device 100 in the above technical solution, and the floor brush device 100 is movably connected with the device main body 200. When a user performs a cleaning operation, the floor brush device 100 can be moved by pushing or pulling the device main body 200.
[0133] It can be understood that a sewage suction pipeline can be connected between the floor brush device 100 and the device main body 200, and a sewage tank can be arranged on the device main body 200, so that the sewage sucked from the floor brush device 100 can enter the sewage tank through the sewage suction pipeline.
[0134] In addition, a fan unit can be arranged on the device main body 200, and the fan unit is used to form a negative pressure air flow, so as to generate a negative pressure suction force on the first suction port 102 and the second suction port 105. The clean air flow filtered by the sewage tank is discharged to the outside of the device main body 200 after passing through the fan unit.
[0135] The embodiment of the present application provides a floor brush device and a cleaning equipment. The floor brush device comprises a device main body, a water scraping assembly, a water separating assembly and a water spraying assembly. The device main body has a floor brush air duct. The water scraping assembly, the water separating assembly and the water spraying assembly are arranged on the device main body. In the cleaning direction of the floor brush device, the water separating assembly is located on the front side of the water scraping assembly. The water separating assembly and the water scraping assembly have a gap therebetween, the gap is communicated with the floor brush air duct, and one end of the gap towards the lower side of the device main body forms a first suction port. The water spraying assembly is configured to supply water to the area below the floor brush device towards which the first suction port is directed, so that the rolling brush is cancelled. The floor brush device has a good cleaning effect, and the sewage will not be left on the floor brush device, so that the floor brush device will not produce an odor when it is placed after cleaning.
