For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0034] With the development of smart and convenient cleaning appliances, floor scrubbers, as efficient cleaning devices that integrate vacuuming, mopping, and drying, are experiencing continuous market demand growth. The nozzle, as the core component of the floor scrubber, directly affects the ease of use and maintenance efficiency of the cleaning equipment due to its connection method with the brush body. Early cleaning equipment often used fixed connections for nozzles, which could not be disassembled. When the nozzle became clogged or damaged, the entire component needed to be replaced, resulting in high operating costs.

[0035] In related technologies, the nozzle is detachably connected to the brush body using a threaded connection to solve the problem of the nozzle being unable to be removed. However, the threaded connection still has the following problems: 1. Threaded connections require multiple rotations to assemble or disassemble the nozzle, which is time-consuming and cannot meet the needs of rapid maintenance, especially when the nozzle needs to be frequently replaced during cleaning operations, which seriously affects work efficiency; 2. Threaded assembly has high requirements for centering. If there is a misalignment, stripping is likely to occur. Moreover, after long-term use, dirt can easily accumulate on the thread surface or cause wear, making disassembly difficult and requiring the use of tools; 3. Vibration generated during operation can easily cause the threaded connection to loosen, which may lead to water leakage or nozzle misalignment, affecting the cleaning effect and even posing a safety hazard; 4. Threaded connections cannot be visually confirmed to be properly assembled. Users may cause an insecure connection due to insufficient rotation angle or damage to components due to excessive rotation.

[0036] To address the aforementioned problems, this application proposes a floor brush and cleaning device.

[0037] An embodiment of the first aspect of this application provides a floor brush for use in cleaning equipment, such as a floor scrubber. Please refer to... Figure 1 and Figure 5 The floor brush 100 includes a floor brush body 10, a base 20, and a nozzle 30. The base 20 is located on the floor brush body 10. A quick-release structure is provided between the base 20 and the nozzle 30. The nozzle 30 is detachably connected to the base 20 through the quick-release structure.

[0038] Understandably, the base 20 can be fixedly connected to the brush body 10 by means of snap-fit, fastener connection, magnetic connection, etc.; or, the base 20 can be integrally formed with the brush body 10.

[0039] During cleaning, the base 20 is located at the front end of the floor brush body 10. Understandably, after the nozzle 30 is connected to the base 20, the nozzle 30 is located in front of and above the mopping member 11. Before the mopping member 11 mops the surface to be cleaned (e.g., the ground), the surface to be cleaned is pre-wetted with liquid (e.g., water or cleaning solution) sprayed from the nozzle 30 to improve cleaning efficiency.

[0040] It should be noted that the nozzle 30 in this application is a fan-shaped nozzle capable of spraying a fan-shaped mist, which can basically cover the area in front of the mopping component 11. The nozzle 30 can be a metal nozzle.

[0041] Understandably, the mopping component 11 can be a roller mop, a disc mop, or a tracked mop, etc.

[0042] The floor brush 100 provided in this application embodiment includes a floor brush body 10, a base 20, and a nozzle 30. The base 20 is disposed on the floor brush body 10. Compared with the base 20 on which the nozzle 30 is threadedly connected to the floor brush body 10, since the nozzle 30 of this application is detachably connected to the base 20 on the floor brush body 10 through a quick-release structure, multiple rotation operations are not required when assembling or disassembling the nozzle 30, thereby improving the assembly and disassembly efficiency.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the quick-release structure includes a snap-fit ​​311 and a snap-fit ​​hole 21 that engages with the snap-fit ​​311. The snap-fit ​​hole 21 is located on the base 20, and the snap-fit ​​311 is located on the nozzle 30.

[0044] Understandably, there are multiple locking holes 21, and correspondingly, there are multiple locking clips 311, with each locking hole 21 arranged in a one-to-one correspondence. Multiple locking clips 311 are engaged with multiple locking holes 21 to improve the stability of the nozzle 30 connected to the base 20. The locking clips 311 are cantilever structures made of elastically deformable plastic.

[0045] For example, the base 20 has a long strip structure, and two locking holes 21 are arranged at intervals along the length of the base 20. Correspondingly, two buckles 311 are provided. The length of the base 20 is horizontal, which reduces the space occupied by the base 20 in the vertical direction.

[0046] During installation, the clip 311 of the nozzle 30 engages with the locking hole 21 of the base 20, allowing for quick installation of the nozzle 30 onto the base 20. During disassembly, pressing the free end of the clip 311 disengages it from the locking hole 21, enabling quick removal of the nozzle 30. A clicking sound is emitted when the clip 311 of the nozzle 30 is fully engaged with the locking hole 21 of the base 20, indicating that the installation is complete.

[0047] The nozzle 30 includes a nozzle body 32 and a cap 31 fitted on the nozzle body 32. The nozzle body 32 is used for spraying water, and the buckle 311 is provided on the cap 31.

[0048] Based on the above technical solution, the nozzle 30 is snapped onto the base 20 to achieve quick disassembly of the nozzle 30 onto the base 20. For example, quick disassembly can be achieved within 3 seconds, which significantly improves the disassembly and assembly efficiency compared to threaded connections.

[0049] In some other embodiments, the locating hole 21 may be provided on the nozzle 30, and the latch 311 may be provided on the base 20.

[0050] Please refer to Figure 3In some embodiments, the buckle 311 includes a spring arm 3111 and a snap-fit ​​protrusion 3112 protruding from one side of the spring arm 3111. The snap-fit ​​protrusion 3112 has a snap-fit ​​surface 31121, and the snap-fit ​​surface 31121 is provided with anti-slip texture.

[0051] Understandably, anti-slip textures can be stripes, for example, the cross-section of a stripe can be triangular; or, anti-slip textures can also be conical protrusions.

[0052] Understandably, with two clips 311, there are two spring arms 3111 and two locking protrusions 3112. The two locking protrusions 3112 can be positioned on opposite sides of the two spring arms 3111, allowing for easy disassembly of the nozzle 30 by pressing the two spring arms 3111 together with two fingers. Alternatively, the two locking protrusions 3112 can be positioned on opposite sides of the two spring arms 3111, allowing for easy disassembly of the nozzle 30 by spreading the two spring arms 3111 apart with two fingers.

[0053] Based on the above technical solution, when the buckle 311 engages with the buckle hole 21, the anti-slip texture can increase the friction at the engagement surface. Combined with the pre-tightening force of the buckle 311, it can effectively prevent the connection from loosening due to working vibration and avoid water leakage caused by the nozzle 30 shifting.

[0054] Please refer to Figure 3 In some embodiments, a guide portion 211 is provided in the card hole 21 to guide the buckle 311 into the card hole 21. The guide portion 211 includes a guide slope, which can be a straight slope or an arc-shaped slope.

[0055] Please refer to Figures 6 to 8 In some embodiments, the quick-release structure includes a first magnetic element 22 and a second magnetic element 312 magnetically connected to the first magnetic element 22. The first magnetic element 22 is disposed on the base 20, and the second magnetic element 312 is disposed on the nozzle 30.

[0056] Understandably, both the first magnetic component 22 and the second magnetic component 312 can be magnets; or, the first magnetic component 22 can be a magnet and the second magnetic component 312 can be an iron component; or, the first magnetic component 22 can be an iron component and the second magnetic component 312 can be a magnet. The magnets can be permanent magnets, and the iron components can be stainless iron.

[0057] Understandably, there are multiple first magnetic elements 22, and correspondingly, there are multiple second magnetic elements 312. The stability of the nozzle 30 connected to the base 20 is improved by magnetically attracting multiple first magnetic elements 22 with multiple second magnetic elements 312. For example, the base 20 may be a long strip structure, with two first magnetic elements 22 spaced apart along the length of the base 20, and correspondingly, two second magnetic elements 312; or, the base 20 may be a disc structure, with three, four, or five or more first magnetic elements 22 spaced apart along the circumference of the base 20, and correspondingly, three, four, or five or more second magnetic elements 312.

[0058] Understandably, the number of the first magnetic element 22 can also be one, and correspondingly, the number of the second magnetic element 312 can also be one. For example, if the base 20 has a disc-shaped structure, the first magnetic element 22 is a ring-shaped magnetic element, and correspondingly, the second magnetic element 312 is a ring-shaped magnetic element, which can also improve the stability of the nozzle 30 connected to the base 20.

[0059] During installation, simply bring the nozzle 30 close to the base 20, and the magnetic attraction between the first magnetic component 22 and the second magnetic component 312 will allow the nozzle 30 to be quickly installed on the base 20. During disassembly, simply pull to overcome the magnetic attraction to remove the nozzle 30 from the base 20.

[0060] The nozzle 30 includes a nozzle body 32 and a cap 31 fitted on the nozzle body 32. The nozzle body 32 is used for spraying water, and a second magnetic element 312 is provided on the cap 31.

[0061] Based on the above technical solution, the second magnetic component 312 of the nozzle 30 is magnetically attracted to the first magnetic component 22 of the base 20, so as to realize the quick disassembly of the nozzle 30 on the base 20, which significantly improves the disassembly and assembly efficiency compared with the threaded connection.

[0062] In some other embodiments, the locating hole 21 may be provided on the nozzle 30, and the latch 311 may be provided on the base 20.

[0063] Please refer to Figure 7 and Figure 8 In some embodiments, the nozzle 30 is provided with a positioning protrusion 314, and the seat 20 is provided with a positioning groove 24 that positions and cooperates with the positioning protrusion 314.

[0064] Understandably, one positioning groove 24 can be provided, and correspondingly, one positioning protrusion 314 can be provided; or, multiple positioning grooves 24 can be provided, and correspondingly, multiple positioning protrusions 314 can be provided.

[0065] For example, the base 20 has a long strip structure, and two positioning grooves 24 are provided. The two positioning grooves 24 are arranged at intervals along the length of the base 20. Correspondingly, two positioning protrusions 314 are provided.

[0066] Understandably, the positioning groove 24 can be a conical groove, and correspondingly, the positioning protrusion 314 is a conical protrusion.

[0067] Based on the above technical solution, during the magnetic attraction process of the first magnetic component 22 and the second magnetic component 312, the positioning groove 24 and the positioning protrusion 314 are positioned and cooperated to achieve automatic alignment between the nozzle 30 and the seat 20, ensuring the uniformity of the force on the sealing ring 322. Combined with the magnetic attraction pressure, the sealing performance is improved, avoiding water flow obstruction or leakage caused by misalignment; at the same time, the service life of the sealing ring 322 is increased.

[0068] In some other embodiments, the positioning protrusion 314 may be provided on the base 20, and the positioning groove 24 may be provided on the nozzle 30.

[0069] Please refer to Figures 7 to 10 In some embodiments, the first magnetic element 22 is arranged correspondingly to the positioning groove 24, and the second magnetic element 312 is arranged correspondingly to the positioning protrusion 314.

[0070] The first magnetic element 22 is arranged correspondingly to the positioning groove 24. This can be understood as the center line of the first magnetic element 22 coinciding with or substantially coinciding with the center line of the positioning groove 24.

[0071] For example, the base 20 is provided with a first mounting hole 221, and the first magnetic element 22 is installed in the first mounting hole 221. The first mounting hole 221 can be a blind hole or a through hole. When the first mounting hole 221 is a blind hole, its opening faces away from the pressure cover 31, so that the first magnetic element 22 and the second magnetic element 312 do not contact each other when magnetically attracted, avoiding noise during magnetic attraction. Of course, when the first mounting hole 221 is a blind hole, its opening can also face the pressure cover 31.

[0072] Understandably, the first magnetic element 22 can be cylindrical, and correspondingly, the first mounting hole 221 is a circular hole; or, the first magnetic element 22 can be prismatic, and correspondingly, the first mounting hole 221 is a polygonal hole.

[0073] The second magnetic element 312 is arranged correspondingly to the positioning protrusion 314. This can be understood as the center line of the second magnetic element 312 coinciding with or substantially coinciding with the center line of the positioning protrusion 314.

[0074] For example, the pressure cap 31 is provided with a second mounting hole 313, and the second magnetic element 312 is installed in the second mounting hole 313. The second mounting hole 313 can be a blind hole or a through hole; when the second mounting hole 313 is a blind hole, its opening faces the base 20. Of course, when the second mounting hole 313 is a blind hole, its opening can also face away from the base 20.

[0075] Understandably, the second magnetic element 312 can be cylindrical, and correspondingly, the second mounting hole 313 is a circular hole; or, the second magnetic element 312 can be prismatic, and correspondingly, the second mounting hole 313 is a polygonal hole.

[0076] By arranging the first magnetic element 22 in correspondence with the positioning groove 24, the size of the base 20 can be reduced; by arranging the second magnetic element 312 in correspondence with the positioning protrusion 314, the size of the pressure cap 31 can be reduced.

[0077] In other embodiments, the first magnetic element 22 and the positioning groove 24 may be arranged in a staggered manner, and correspondingly, the second magnetic element 312 and the positioning protrusion 314 may be arranged in a staggered manner.

[0078] Please refer to Figure 2 and Figure 3 In some embodiments, the nozzle 30 includes a nozzle body 32 and a cap 31 sleeved on the nozzle body 32, and a quick-release structure is provided between the base 20 and the cap 31; when the cap 31 is connected to the base 20 through the quick-release structure, the cap 31 presses and fixes the nozzle body 32 to the base 20.

[0079] When the quick-release structure includes a snap-fit ​​311 and a locking hole 21, the snap-fit ​​311 is located on the pressure cap 31, and the locking hole 21 is located on the base 20. During installation, the snap-fit ​​311 of the pressure cap 31 snaps into the locking hole 21 of the base 20 to fix the pressure cap 31 to the base 20, and at the same time, the pressure cap 31 presses and fixes the nozzle body 32 to the base 20. During disassembly, pressing the free end of the snap-fit ​​311 allows the snap-fit ​​311 to disengage from the locking hole 21, so that the pressure cap 31 can be quickly removed from the base 20, and the nozzle body 32 can also be removed at the same time.

[0080] When the quick-release structure includes a first magnetic component 22 and a second magnetic component 312, the first magnetic component 22 is located on the base 20, and the second magnetic component 312 is located on the pressure cap 31. During installation, the first magnetic component 22 on the base 20 and the second magnetic component 312 on the pressure cap 31 are magnetically attracted to each other, so that the pressure cap 31 is fixedly connected to the base 20, and the pressure cap 31 presses and fixes the nozzle body 32 to the base 20. During disassembly, the pressure cap 31 can be removed from the base 20 by simply pulling to overcome the magnetic attraction, and the nozzle body 32 can also be removed at the same time.

[0081] The nozzle 30 in this embodiment includes a nozzle body 32 and a pressure cap 31. When the pressure cap 31 is fixedly connected to the base 20, it presses and fixes the nozzle body 32 to the base 20. That is, the nozzle 30 has a split structure to facilitate the processing of the nozzle 30.

[0082] In some other embodiments, the nozzle 30 is a single unit, that is, the nozzle body 32 and the cap 31 are an integral structure.

[0083] Please refer to Figure 3 and Figure 4 The pressure cap 31 is provided with an anti-mistake protrusion 315, and the nozzle body 32 is provided with an anti-mistake groove 321.

[0084] Understandably, one or more error-proof protrusions 315 may be provided, and correspondingly, one or more error-proof grooves 321 may be provided.

[0085] For example, when there are two anti-mistake protrusions 315, there are correspondingly two anti-mistake grooves 321. Understandably, when the arrangement direction of the two anti-mistake grooves 321 is perpendicular to the fan-shaped surface ejected from the nozzle body 32, the arrangement direction of the two anti-mistake protrusions 315 is correspondingly perpendicular to the arrangement direction of the two latches 311; when the arrangement direction of the two anti-mistake grooves 321 is parallel to the fan-shaped surface ejected from the nozzle body 32, the arrangement direction of the two anti-mistake protrusions 315 is correspondingly parallel to the arrangement direction of the two latches 311.

[0086] Based on the above technical solution, the position of the nozzle body 32 can be accurately guaranteed when the pressure cap 31 presses and fixes the nozzle body 32 onto the base 20, thereby ensuring that the fan-shaped surface sprayed by the nozzle body 32 is parallel to the axial direction of the wiping component 11. At the same time, it can prevent the nozzle body 32 from rotating after installation.

[0087] In some other embodiments, the anti-mistake protrusion 315 may be provided on the nozzle body, and the anti-mistake groove 321 may be provided on the cap 31.

[0088] Please refer to Figure 7 and Figure 12 In some embodiments, the base 20 is provided with a mounting cavity 25, a portion of the nozzle body 32 is located within the mounting cavity 25, and a sealing ring 322 is provided between the outer peripheral surface of the nozzle body 32 and the cavity wall of the mounting cavity 25.

[0089] Understandably, the outer peripheral surface of the nozzle 32 or the cavity wall of the mounting cavity 25 is provided with a sealing ring groove, and the sealing ring 322 is located in the sealing ring groove.

[0090] Compared to placing the sealing ring 322 between the end face of the nozzle body 32 and the cavity wall of the mounting cavity 25, placing the sealing ring 322 between the outer peripheral surface of the nozzle body 32 and the cavity wall of the mounting cavity 25 ensures that the sealing ring 322 is properly compressed, avoiding problems such as poor sealing due to insufficient compression or damage to the sealing ring 322 due to excessive compression.

[0091] In some embodiments, the quick-release structure includes a suction cup disposed on the base 20 or the nozzle 30, which is used to adhere and fix the nozzle 30 to the base 20. The suction cup can be a vacuum suction cup, equipped with a vacuum pump and a negative pressure pipeline. The vacuum pump is connected to the vacuum suction cup via the negative pressure pipeline to adjust the suction force.

[0092] Please refer to Figure 2 and Figure 3 In some embodiments, the base 20 is detachably connected to the brush body 10.

[0093] For example, the brush body 10 has a threaded hole, the base 20 has a fixing hole 231, and the base 20 is fixed to the brush body 10 by fixing screws 23.

[0094] Understandably, multiple fixing holes 231 can be provided, and correspondingly, multiple fixing screws 23 can be provided to ensure the stability of the seat 20 fixed on the brush body 10. For example, the seat 20 is a long strip structure, and two fixing holes 231 are arranged at intervals along the length of the seat 20.

[0095] Please refer to Figure 11 and Figure 12 In some embodiments, the floor brush 100 also includes a water pipe 40, the first end 41 of which is connected to the base 20, and the base 20 is provided with a first one-way valve 50.

[0096] The base 20 is provided with a first connector 28, which is connected to the first end 41 of the water pipe 40. At the same time, the first connector 28 connects the water pipe 40 and the mounting cavity 25, that is, the water in the water pipe 40 can enter the nozzle body 32 through the first connector 28.

[0097] Understandably, during operation, the first check valve 50 can open under water pressure to allow the nozzle body 32 to spray water outward; when operation stops, with no water pressure or low water pressure, the first check valve 50 closes to block the water path, so that no water will flow out when the nozzle body 32 is replaced.

[0098] Please refer to Figure 12 and Figure 13In some embodiments, the seat 20 has a connection hole 26 and a plurality of water passage holes 27 arranged around the connection hole 26. The first one-way valve 50 is an umbrella valve, which includes a rod 51 and an umbrella body 52 connected to the rod 51. The rod 51 is connected to the connection hole 26, and the umbrella body 52 covers the plurality of water passage holes 27.

[0099] Understandably, two, three, four or more water passage holes 27 can be arranged at intervals around the connecting hole 26. The shape of the water passage holes 27 can be fan-shaped, circular, elliptical, rectangular, or other shapes.

[0100] The rod 51 is snapped into the connection hole 26 to fix the first one-way valve 50 to the seat 20; the umbrella body 52 is located in the mounting cavity 25 and is used to block the end of the water passage hole 27 near the nozzle body 32.

[0101] Understandably, during operation, under water pressure, water flows into the water passage 27 and pushes open the umbrella body 52 to open the water path, and water is sprayed outward through the nozzle body 32; when operation stops, there is no water pressure or the water pressure is low, the umbrella body 52 covers the water passage 27 again to block the water path, so that no water will flow out when the nozzle body 32 is replaced.

[0102] Please refer to Figure 11 and Figure 14 In some embodiments, the floor brush body 10 is provided with a male connector 60, a female connector 70 and an adapter cap 80 inside. The male connector 60 is inserted into the female connector 70 and is sealed to the female connector 70. The adapter cap 80 is fitted onto the female connector 70 and is sealed to the female connector 70. The second end 42 of the water pipe 40 is connected to the adapter cap 80. The female connector 70 is provided with a second one-way valve 90.

[0103] The adapter cap 80 is equipped with a second connector 81, which is connected to the water pipe 40. During operation, water enters the female connector 70 through the male connector 60, then enters the adapter cap 80 through the second one-way valve 90, and finally enters the water pipe 40.

[0104] Understandably, during operation, the second check valve 90 can open under water pressure to supply water to the nozzle body 32; when operation stops, with no water pressure or low water pressure, the second check valve 90 closes to block the water path.

[0105] Please refer to Figure 14 In some embodiments, the second one-way valve 90 is a duckbill valve, and the female connector 70 is also provided with a pressure sleeve 71, which is used to press and fix the duckbill valve to the female connector 70.

[0106] The duckbill valve has a valve disc length designed to be 1.5 times the outlet diameter to ensure complete valve disc fit during reverse sealing.

[0107] In some embodiments, a duckbill valve (one component) is provided on the female connector 70, and an umbrella valve (one component) is provided inside the seat 20, which facilitates assembly and reduces costs; at the same time, it achieves dual-node leak prevention. Among them, the duckbill valve has the characteristics of simple structure and no moving parts, and is suitable for high-flow nodes with low-frequency disassembly and assembly (i.e., at the female connector 70). The umbrella valve, with its characteristics of fast response and small size, is suitable for low-flow nodes with high-frequency disassembly and assembly (i.e., at the nozzle 30), so as to meet the corresponding requirements under different pressures and reduce the likelihood of problems such as delayed opening at the female connector 70 or poor sealing at the nozzle 30.

[0108] In some other embodiments, duckbill valves may be provided on both the female connector 70 and the seat 20; or, umbrella valves may be provided on both the female connector 70 and the seat 20; or, the female connector 70 may be provided with a duckbill valve and the seat 20 may be provided with an umbrella valve.
