[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0056] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.
[0057] In related technologies, cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean the floor. The floor brush adopts a front suction and rear mopping structure. The suction port on the front side can suck up garbage and debris on the floor, and the roller brush on the rear side rolls on the floor to achieve the effect of wet mopping.
[0058] However, when cleaning with a roller brush, water stains are easily left on the surface to be cleaned, and the roller brush is prone to sticking to garbage and debris, leading to mold and odor.
[0059] To address the aforementioned technical problems, this application provides a floor brush device that can rinse the surface to be cleaned via a first water spray module and suck up cleaning wastewater and residual water stains through a suction port, achieving brushless cleaning, reducing mold and odor, and minimizing water stain residue. Additionally, the floor brush device is equipped with a self-cleaning module that can self-clean the internal cavity walls, reducing the cleaning difficulty for cleaning personnel.
[0060] The following is an example illustrating the application scenarios of the floor brush device provided in the embodiments of this application.
[0061] 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 types of products to which the floor brush device in this application embodiment can be applied include, but are not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the floor brush device 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.
[0062] Figure 1 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 2 This is a bottom schematic diagram of the floor brush device provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the cleaning component provided in the embodiments of this application; Figure 4 An exploded view of the cleaning component provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the first scraping component provided in an embodiment of this application; Figure 6 This is a schematic diagram of the structure of the second scraping component provided in an embodiment of this application.
[0063] See Figures 1 to 6 As shown, this application provides a floor brush device 10, which can move on and clean the surface to be cleaned. The floor brush device 10 includes a main body 100 and a cleaning component 200. The main body 100 carries different cleaning parts, and the cleaning component 200 is used to clean the surface to be cleaned. The cleaning component 200 is connected to the main body 100, and the cleaning component 200 and the main body 100 can be connected by a snap-fit mechanism or by a magnetic component. The main body 100 has a floor brush air duct 110, which can be connected to a suction element. The floor brush air duct 110 has an air inlet 111 facing the surface to be cleaned. When the floor brush device 10 cleans the surface, the suction element is activated, and the air inlet 111 generates negative pressure suction. Airflow can carry cleaning wastewater, dust, and debris from the air inlet 111 into the floor brush air duct 110, and then into a collection device inside the main body 100.
[0064] For example, the cleaning component 200 includes a cleaning body 210 and a first water spray module 221. The cleaning body 210 is connected to the device body 100 via a snap-fit mechanism. The cleaning body 210 has a snap-fit part 212, and the top of the snap-fit part 212 has a snap-fit protrusion 2121. The two end walls of the receiving groove 120 have snap-fit holes. When the cleaning body 210 is installed, it is inserted into the receiving groove 120 from bottom to top. During the insertion process, the snap-fit part 212 abuts against the two end walls of the receiving groove 120, and the snap-fit part 212 undergoes elastic deformation. When the snap-fit part 212 reaches the snap-fit hole, the snap-fit part 212 returns to its original shape, and the snap-fit protrusion 2121 slides into the snap-fit hole to achieve a secure snap-fit. When disassembling, the snap-fit protrusions 2121 on both sides are pressed at the same time to disengage the snap-fit protrusions 2121 from the snap-fit hole. At this time, the cleaning body 210 can be pulled out of the receiving groove 120 to complete the disassembly.
[0065] In some embodiments, the cleaning body 210 is located below the air inlet 111, and the cleaning body 210 has a suction port 211 communicating with the air inlet 111; the first water spray module 221 is connected to the lower part of the cleaning body 210, and the first water spray module 221 is configured to spray cleaning water onto the surface to be cleaned below the cleaning body 210; the suction port 211 is located beside the first water spray module 221, so that the cleaning water sprayed onto the surface to be cleaned is sucked into the floor brush duct 110 from the suction port 211.
[0066] Understandably, the floor brush device 10 cleans the surface to be cleaned through the cleaning component 200. When the floor brush device 10 is cleaning, the first water spray module 221 can spray cleaning water onto the surface to be cleaned. The cleaning water can rinse the surface to be cleaned and pick up dust, hair and debris. At the same time, the air intake generates negative pressure suction, so that the suction port 211 can suck in the cleaning water containing dust, hair and debris, and enter the collection device through the floor brush air duct 110, thereby completing the cleaning process of the surface to be cleaned.
[0067] As one possible implementation, along the cleaning direction of the floor brush device 10, the suction port 211 is located on the front and / or rear side of the first water spray module 221.
[0068] See Figure 1 , Figure 2 The direction of movement of the floor brush device 10 during cleaning is defined as the X direction, and the width direction of the floor brush device 10 is defined as the Y direction, which is perpendicular to the x-axis. Figure 1 The orientation of the paper is Y-axis, which is perpendicular to X-axis.
[0069] It is understandable that, along the cleaning direction of the floor brush device 10, i.e., along the X direction, the suction port 211 can be located in front of the first water spray module 221, or behind the first water spray module 221, or both in front of and behind the first water spray module 221. With the suction port 211 close to the first water spray module 221, after the first water spray module 221 sprays cleaning water to rinse the surface to be cleaned, the suction port 211 can suck up the rinsed wastewater and the debris carried by the wastewater.
[0070] As one possible implementation, the suction port 211 includes a first suction port 211a and a second suction port 211b. The first suction port 211a is located on the front side of the first water spray module 221 along the cleaning direction of the floor brush device 10, and the second suction port 211b is located on the rear side of the first water spray module 221 along the cleaning direction of the floor brush device 10.
[0071] It is understandable that having two suction ports on the front and rear sides of the first water spray module 221 can improve the absorption rate of cleaning wastewater, and the floor brush device 10 has a suction port to absorb residual water stains when moving forward or backward. Among them, the first suction port 211a and the second suction port can be flat suction ports, which can increase the suction power without changing the power of the suction element.
[0072] In one possible implementation, the cleaning component 200 includes a first scraping component 223 and a second scraping component 224, both of which are connected to the cleaning body 210. The first scraping component 223 is located on the front side of the first water spray module 221 along the cleaning direction of the floor brush device 10, and the first suction port 211a is located between the first water spray module 221 and the first scraping component 223. The second scraping component 224 is located on the rear side of the first water spray module 221 along the cleaning direction of the floor brush device 10, and the second suction port 211b is located between the first water spray module 221 and the second scraping component 224.
[0073] Understandably, the first scraping component 223 and the second scraping component 224 are used to scrape the surface to be cleaned to remove stubborn stains, adhering debris, and cleaning water stains. The first scraping component 223 and the second scraping component 224 are spaced apart along the cleaning direction, and they prevent water from the first water spray module 221 from splashing into the surrounding environment. The first water spray module 221, the two suction ports, and the two scraping components work together to clean the surface without the need for a roller brush.
[0074] As one possible implementation, when the floor brush device 10 cleans the surface to be cleaned, both the first scraping component 223 and the second scraping component 224 are in contact with the surface to be cleaned, and a cleaning cavity 215 is formed between the first scraping component 223 and the second scraping component 224.
[0075] It should be noted that the first scraping assembly 223 may include a first scraping blade 2232 and a first scraping strip 2233. The first scraping blade 2232 may be provided with multiple first slots 2231, and the cleaning body 210 is provided with a first mounting groove 213. The first mounting groove 213 may be provided with multiple first engaging protrusions 2131 that match the first slots 2231. The upper and lower surfaces of the first engaging protrusions 2131 may be inclined towards the center to form two inclined surfaces. When the first scraping assembly 223 is inserted into the first mounting groove 213, the first scraping assembly 223 may slide in along the upper inclined surface of the first engaging protrusions 2131. In the first mounting groove 213, until the first snap-fit protrusion 2131 snaps into the first slot 2231, the first snap-fit protrusion 2131 can limit the first scraping component 223 to prevent the first scraping component 223 from falling off or loosening during the cleaning process; when the first scraping component 223 is disassembled, only an upward external force needs to be applied to the first scraping component 223 to make the first slot 2231 slide out along the lower inclined surface of the first snap-fit protrusion 2131. At this time, the first slot 2231 and the first snap-fit protrusion 2131 are disengaged, so that the first scraping component 223 can be taken out from the first mounting groove 213.
[0076] Similarly, the second scraping assembly 224 may include a second scraper 2242 and a second scraper 2243. The second scraper 2242 may be provided with a plurality of second slots 2241. The cleaning body 210 is provided with a second mounting groove 214. The second mounting groove 214 may be provided with a plurality of second engaging protrusions 2141 that match the second slots 2241. The connection method between the second scraping assembly 224 and the cleaning body 210 is the same as the connection method between the first scraping assembly 223 and the cleaning body 210.
[0077] Understandably, after the first scraping assembly 223 and the second scraping assembly 224 are connected to the cleaning body 210, the first scraper 2233 and the second scraper 2243 extend downward and contact the surface to be cleaned. The first scraper 2233 and the second scraper 2243 are made of soft rubber material, which can deform after contact with the surface to be cleaned. During the movement of the floor brush device 10, the first scraper 2233 and the second scraper 2243 slide and rub against the surface to be cleaned to scrape away stains, water stains and debris from the surface to be cleaned.
[0078] As one possible implementation, the first suction port 211a has a first air guide wall 217 on the side near the first water spray module 220; the first air guide wall 217 is inclined away from the first scraping assembly 223 in the suction path of the first suction port 211a; the second suction port 211b has a second air guide wall 218 on the side near the first water spray module 220; the second air guide wall 218 is inclined away from the second scraping assembly 224 in the suction path of the second suction port 211b.
[0079] Understandably, the top of the cleaning body 210 is provided with a triangular prism extending along the length of the cleaning body 210. The length of the triangular prism can match the length of the cleaning body 210. One side of the triangular prism is fixedly connected to the cleaning body 210, and the other two sides form the first air guide wall 217 and the second air guide wall 218. At the air inlet 111, the triangular prism separates the two airflows from the first suction port 211a and the second suction port 211b, preventing the two airflows from merging at a certain angle, generating turbulence, and reducing absorption efficiency. By guiding the airflows from the first suction port 211a and the second suction port 211b through the first air guide wall 217 and the second air guide wall 218, turbulence can be prevented after the two airflows merge, thus improving suction efficiency.
[0080] As one possible implementation, the first water spray module 221 extends along the width direction of the device body 100; wherein the width direction of the device body 100 is perpendicular to the cleaning direction of the floor brush device 10; the first scraping component 223 and the second scraping component 224 are both arranged parallel to the first water spray module 221; the lengths of the first scraping component 223 and the second scraping component 224 are both matched with the length of the first water spray module 221.
[0081] It is understood that the first water spray module 221 extends along the Y direction, the width direction of the device body 100 is the Y direction, and the length direction of the first scraping component 223 and the second scraping component 224 is also in the Y direction. The lengths of the first scraping component 223 and the second scraping component 224 are matched with the length of the first water spray module 221, so that the first scraping component 223 and the second scraping component 224 can block splashed water stains on the front and rear sides of the first water spray module 221 along the X direction. Regardless of whether the floor brush device 10 moves forward or backward along the X direction, the scraping area of the first scraping component 223 and the second scraping component 224 can cover the water spraying area of the first water spray module 221, which can effectively remove water stains from the surface to be cleaned. At the same time, when the first water spray module 221 sprays water, the suction port 211 draws air, causing the airflow to flow from both ends of the device body 100 towards the middle, which can prevent water stains from splashing into the surrounding environment along the Y direction.
[0082] As one possible implementation, the first water spray module 221 is provided with a plurality of water spray holes 2213 on the side facing the lower part of the device body 100, and the plurality of water spray holes 2213 are arranged at intervals along the length direction of the first water spray module 221.
[0083] It is understandable that multiple water spray holes 2213 are arranged at intervals along the Y direction, and can be arranged at equal or unequal intervals. The number of water spray holes 2213 is at least two, and the water spray holes 2213 are used to spray cleaning water onto the surface to be cleaned.
[0084] For example, the number of water spray holes 2213 can be 2, 3, 4, 5, etc., and this application embodiment does not make a specific limitation.
[0085] As one possible implementation, the first suction port 211a and the second suction port 211b are both opposite to the middle position of the first water spray module 221 in the length direction; the cleaning chamber 215 has airflow inlets 2161 at both ends in the width direction of the device body 100, and at least some of the water spray holes 2213 are set close to the airflow inlets 2161 so that the airflow drives the cleaning water sprayed into the cleaning chamber 215 to flow from the airflow inlets 2161 to the first suction port 211a and the second suction port 211b.
[0086] See Figure 2 As shown, the first suction port 211a and the second suction port 211b are both located in the middle of the cleaning body 210 along the Y direction and are separated by the first water spray module 221.
[0087] For example, there can be four water spray holes 2213, which are equidistantly arranged along the Y direction. Two of the water spray holes 2213 are located at both ends of the cleaning chamber 215, respectively close to the airflow inlets 2161 at both ends of the cleaning chamber 215. When the floor brush device 10 performs cleaning work, the water pump draws cleaning water from the water tank to supply water to the water inlet and provides water pressure. The water flow is sprayed from the four water spray holes 2213 onto the surface to be cleaned in the cleaning chamber 215. At the same time, the air inlet 111 generates negative pressure suction, which causes the cleaning chamber 215 to generate two airflows from the airflow inlets 2161 at both ends to the first suction port 211a and the second suction port 211b in the middle. During the flow, the two airflows can pick up the garbage and cleaning wastewater on the surface to be cleaned and bring it into the first suction port 211a and the second suction port 211b.
[0088] Understandably, during the cleaning process, on the one hand, the jets sprayed from the four water nozzles 2213 can directly rinse a portion of the surface to be cleaned; on the other hand, the cleaning water sprayed from the two water nozzles 2213 at both ends of the cleaning chamber 215 will flow towards the first suction port 211a and the second suction port 211b in the middle under the influence of the airflow. During the water flow, the surface to be cleaned can be rinsed along the length of the cleaning chamber 215, and debris can be carried to the first suction port 211a and the second suction port 211b. This allows areas that cannot be directly rinsed by the jets from the water nozzles 2213 to also be rinsed by the water flow. After rinsing, as the floor brush device 10 moves, the first scraper 2233 and the second scraper 2243 can scrape off the residual water stains on the surface to be cleaned. The residual water stains accumulate on the front side of the moving direction of the first scraper 2233 or the second scraper 2243, and are then sucked in by the first suction port 211a or the second suction port 211b.
[0089] As one possible implementation, the bottom of the cleaning body 210 is provided with a mounting groove, and the first water spray module 221 is disposed in the mounting groove; the first water spray module 221 is detachably connected to the cleaning body 210. The first water spray module 221 and the mounting groove can be fixed by bolts or by magnetic materials.
[0090] As one possible implementation, the first water spray module 221 includes a water spray housing 2212 and a first water spray cover plate 2211; the first water spray cover plate 2211 covers the upper side of the water spray housing 2212 and forms a water spray cavity.
[0091] In some embodiments, a plurality of water spray holes 2213 are disposed on the side of the water spray housing 2212 facing the surface to be cleaned, and the water spray holes 2213 communicate with the water spray chamber. The first water spray cover 2211 and the water spray housing 2212 can be integrally formed, or they can be fixedly connected by bolts, magnets, or other means.
[0092] As one possible implementation, the first water spray cover 2211 is provided with a connecting post on the side opposite to the water spray housing 2212, and the cleaning body 210 is provided with a connecting hole; the connecting post is inserted into the connecting hole and connected to the cleaning body 210 by fasteners.
[0093] For example, the cleaning body 210 has four spaced-apart connection holes, and the first spray cover 2211 has four matching connection posts. The four connection posts can be inserted into the four connection holes one by one, and at least part of them protrude from the four connection holes. The connection posts are threaded around their periphery, and the fastener can be a nut. The nut is threaded to the connection post to axially limit the connection post and prevent it from falling out of the connection hole. Alternatively, the connection post is threaded in the middle, and the fastener can be a bolt. The bolt is threaded to the connection post to axially limit the connection post and prevent it from falling out of the connection hole.
[0094] As one possible implementation, the cleaning body 210 is provided with a clearance hole that vertically penetrates the cleaning body 210; the first water spray cover 2211 has a first water inlet connector 2214 on the side opposite to the water spray housing 2212, and the first water inlet connector 2214 passes through the clearance hole; the floor brush device 10 also includes a water supply component, which is connected to the first water inlet connector 2214 and is configured to supply water to the water spray chamber.
[0095] In some embodiments, the water supply assembly includes a water tank and a first water pump. The inlet of the first water pump is connected to the water tank, and the outlet of the first water pump is connected to the first inlet connector 2214. When the first spray module 221 is working, the first water pump draws water from the water tank and can provide a certain pressure. The water flows from the outlet of the first water pump into the first inlet connector 2214, then into the spray chamber, and finally sprays out from the spray hole 2213.
[0096] As one possible implementation, the cleaning body 210 has an air suction chamber 216 that is open to the lower part of the device body 100; the air suction chamber 216 is located on the front side of the first water spray module 221 along the cleaning direction of the floor brush, and the air suction chamber 216 is connected to the suction port 211.
[0097] In some embodiments, the suction port 211 may be provided with a third suction port 211c. The third suction port 211c and the first suction port 211a are separated by the first scraping component 223. The cross-sectional width of the third suction port 211c may be greater than that of the first suction port 211a and the second suction port 211b. The third suction port 211c is located in the middle of the suction chamber 216 and communicates with the air inlet 111. Since the suction chamber 216 is located in front of the first water spray module 221 along the cleaning direction of the floor brush, when the floor brush works along the cleaning direction, the third suction port 211c can first perform a coarse suction on the surface to be cleaned, so that the dust, hair and debris on the surface to be cleaned enter the third suction port 211c along the suction chamber 216 and enter the collection device inside the device body 100 through the floor brush air duct 110. For stubborn stains and sticky debris on the surface to be cleaned, they can be cleaned by the subsequent scraping component, the first suction port 211a and the second suction port 211b, and the first water spray module 221.
[0098] The first scraping component 223 has a ventilation notch 225. The garbage and debris sucked in by the third suction port 211c can enter the first suction port 211a through the ventilation notch 225 with the airflow, which is equivalent to increasing the ventilation flow of the third suction port 211c, thereby improving the absorption efficiency of the third suction port 211c.
[0099] As one possible implementation, the cleaning component 200 also includes a second water spray module 222 disposed on the cleaning body 210 and configured to spray cleaning water to clean the cavity wall of the suction chamber 216.
[0100] In some embodiments, the second water spray module 222 may be provided with a second water spray cover 2221, which covers the cleaning body 210 and surrounds it to form a water spray chamber. The second water spray cover 2221 and the cleaning body 210 may be connected by bolts. The side of the second water spray cover 2221 away from the cleaning body 210 has a second water inlet connector 2223, which is connected to the water supply component. The air suction chamber 216 may be provided with a plurality of water outlets 2222, which are connected to the water spray chamber of the second water spray module 222.
[0101] It should be noted that the water supply assembly may also be equipped with a second water pump. The inlet of the second water pump is connected to the water tank, and the outlet is connected to the second inlet connector 2223. When the second spray module 222 is working, the second water pump draws water from the water tank and provides a certain pressure. The water flows from the outlet of the second water pump into the second inlet connector 2223, then into the spray chamber, and finally sprays out from the outlet hole to the wall of the suction chamber 216 to perform self-cleaning of the wall of the suction chamber 216.
[0102] Understandably, during self-cleaning, the second water pump supplies water to the second spray module 222. At least two water outlets 2222 are located at both ends of the suction chamber 216. The two ends of the suction chamber 216 are connected to the outside, so that when the third suction port 211c draws air, the airflow rushes in from both ends of the suction chamber 216 and flows along the suction chamber 216 into the middle third suction port 211c. The water flow from the water outlets 2222 at both ends of the suction chamber 216 is sprayed onto the cavity wall of the suction chamber 216 and flows along the cavity wall of the suction chamber 216 with the airflow. It is then drawn into the middle third suction port 211c. While the water flow on both sides flows towards the middle third suction port 211c, it can flush the cavity wall of the suction chamber 216, thereby achieving self-cleaning of the entire cavity wall of the suction chamber 216.
[0103] This application provides a floor brush device 10, including a device body 100 and a cleaning component 200. The device body 100 has a floor brush air duct 110, and the floor brush air duct 110 has an air inlet 111 facing downwards from the device body 100. The cleaning component 200 is connected to the device body 100. The cleaning component 200 includes a cleaning body 210 and a first water spray module 221. The cleaning body 210 is located below the air inlet 111 and has a suction port 211 communicating with the air inlet 111. The first water spray module 221 is connected to the lower part of the cleaning body 210 and is configured to spray cleaning water onto the surface to be cleaned below the cleaning body 210. The suction port 211 is located beside the first water spray module 221 so that the cleaning water sprayed onto the surface to be cleaned is sucked into the floor brush air duct 110 from the suction port 211. The floor brush device 10 provided in this application cleans the surface to be cleaned in a brushless manner, and can self-clean up the garbage and debris that sticks to it during the cleaning process, resulting in high cleaning efficiency.
