Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a floor brush device for cleaning equipment, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment is widely used to clean surfaces, bringing great convenience to people's lives. To better meet users' demands for miniaturization and optimized appearance, the size of the cover assembly, used to prevent splashing of debris and / or wastewater from the cleaning components, has also been reduced. However, the reduced size of the cover assembly may lead to insufficient bonding strength between the cover assembly and the brush housing, causing the cover assembly to wobble during use. During cleaning of the surface or self-cleaning of the cleaning components, this wobble results in less cleaning pressure on the sidewalls of the cover assembly, preventing effective cleaning. Consequently, debris and / or wastewater on the inner sidewalls of the cover assembly cannot be thoroughly cleaned, potentially leading to a foul odor. Utility Model Content

[0030] In the floor brush device, cleaning equipment, and cleaning system of this application, the first connecting member of the cover assembly mates with the first joint of the floor brush housing, and the second connecting member of the cover assembly mates with the second joint of the floor brush housing, so that the cover assembly is mounted on the floor brush housing. At this time, the mating structure and the limiting structure cooperate to restrict the rotation of the cover assembly about a axis parallel to the first axis, thereby strengthening the connection between the cover assembly and the floor brush housing. Therefore, the cover assembly can be stably mounted on the floor brush housing, resulting in good structural stability and high structural strength for the floor brush device. During the cleaning process of the cleaning equipment cleaning the surface to be cleaned or the cleaning equipment self-cleaning the cleaning components, the strong bond between the cover assembly and the floor brush housing prevents the cover assembly from shaking. The cleaning pressure exerted by the cleaning components on the sidewalls of the cover assembly facing the cleaning components is high, allowing the cleaning components to effectively clean the cover assembly. Therefore, the garbage and / or sewage on the inner sidewalls of the cover assembly can be thoroughly cleaned without producing a foul odor.

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] Cleaning equipment is widely used to clean surfaces, bringing great convenience to people's lives. To better meet users' demands for miniaturization and improved appearance, the size of the cover assembly used to prevent splashing of debris and / or wastewater from the cleaning components has also been reduced. However, the reduced size of the cover assembly may lead to insufficient bonding strength between the cover assembly and the brush housing, causing the cover assembly to wobble during use. During cleaning of the surface or self-cleaning of the cleaning components, this wobble results in insufficient bonding strength between the cover assembly and the brush housing, leading to less cleaning pressure on the sidewall of the cover assembly facing the cleaning components. Consequently, the cleaning components cannot effectively clean the cover assembly, resulting in incomplete removal of debris and / or wastewater from the inner sidewall of the cover assembly, potentially causing a foul odor. To address this problem, this application provides a brush device for a cleaning equipment (…). Figures 1 to 3 (as shown), cleaning equipment 100 ( Figure 9 (as shown) and cleaning system 1000 ( Figure 10 (As shown).

[0057] Please refer to Figures 1 to 3 In a first aspect, the floor brush device 100 of the cleaning equipment 1000 according to the embodiments of this application includes a floor brush housing 10, a cleaning component 20, and a cover assembly 30. The floor brush housing 10 includes a first connecting portion 11 and a second connecting portion 13. The first connecting portion 11 and the second connecting portion 13 are arranged opposite each other on the left and right sides of the floor brush housing 10 along the forward direction A of the floor brush device 100 for cleaning, and a limiting structure 15 is provided on the floor brush housing 10. The cleaning component 20 is used to clean the surface to be cleaned, and the cleaning component 20 is rotatably disposed on the floor brush housing 10. The cover assembly 30 includes a cover 31, a first connecting member 33, and a second connecting member 35. The first connecting member 33 and the second connecting member 35 are arranged on the left and right sides of the cover 31 along the forward direction A of the floor brush device 100 for cleaning. The first connecting member 33 and the second connecting member 35 are engaged or disengaged from the first connecting portion 11 and the second connecting portion 13, respectively, so that the cover assembly 30 and the floor brush housing 10 can be assembled and disassembled. The cover 31 is provided with a mating structure 37, which mates with the limiting structure 15 to restrict the cover assembly 30 from rotating about the first axis L in the first direction X1 and in the second direction X2. The line connecting the first connector 33 and the second connector 35 is parallel to the first axis L, or the first axis L is parallel to the axis of rotation of the cleaning component 20, and the first direction X1 is opposite to the second direction X2.

[0058] Specifically, the cleaning equipment 1000 is used to remove stains, dust, debris, or microorganisms to maintain environmental hygiene. The cleaning equipment 1000 can be applied in home, commercial, or industrial settings to perform cleaning tasks on surfaces to be cleaned. The cleaning equipment 1000 can be, but is not limited to, a handheld floor scrubber, carpet cleaner, handheld vacuum cleaner, or handheld floor polisher; this application uses a handheld floor scrubber as an example for illustration. The floor brush device 100 is a device in the cleaning equipment 1000 for mounting cleaning components 20 and other elements for cleaning surfaces to be cleaned. It is used to contact the surface to be cleaned with a large contact area and to clean the surface with a certain pressure.

[0059] The brush housing 10 is a structure in the brush unit 100 used to install and house components other than the brush housing 100, such as the cleaning component 20. The brush housing 10 is made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials, or a combination of these materials. For example, the brush housing 10 is made of plastic, which makes the brush unit 100 lighter, reduces its weight, improves its portability, and allows the brush unit 100 to clean surfaces more flexibly and quickly.

[0060] The first joint 11 and the second joint 13 are structures for the floor brush housing 10 to be joined with the cleaning component 20 and / or the cover assembly 30. During the cleaning process of the floor brush device 100 on the surface to be cleaned, the direction of forward movement of the floor brush device 100 in normal cleaning mode is defined as the forward direction A. Figures 1 to 3 The first connecting part 11 and the second connecting part 13 are positioned on the left and right sides of the floor brush housing 10 in the forward direction A.

The connection between the cleaning component 20 and / or the cover assembly 30 and the floor brush housing 10 is more stable, and the structural stability of the floor brush device 100 is better. The limiting structure 15 is a structure on the floor brush housing 10 used to limit the position of the cover assembly 30. The limiting structure 15 can strengthen the bonding strength between the cover assembly 30 and the floor brush housing 10, and prevent the cover assembly 30 from shaking during the use of the cleaning equipment 1000 and / or the floor brush device 100, which would affect the cleaning effect on the surface to be cleaned.

[0061] The cleaning component 20 is a structure in the floor brush device 100 used to clean the surface to be cleaned. The cleaning component 20 is rotatably mounted on the floor brush housing 10 and contacts the surface to be cleaned with a certain contact pressure, so as to achieve cleaning of the surface to be cleaned during rotation. The cleaning component 20 can be, but is not limited to, a cylindrical roller brush, a track roller brush, a rotary disc brush, a scouring pad, an abrasive block, and a scraper, etc., to achieve different cleaning effects on the surface to be cleaned.

[0062] The cover assembly 30 is a component of the floor brush device 100 used to cooperate with the cleaning component 20 to prevent splashed debris and / or wastewater generated by the cleaning component 20 during its rotation to clean the surface to be cleaned. The cover 31 is the main body of the cover assembly 30 and is used to prevent splashed debris and / or wastewater. The first connector 33 and the second connector 35 are structures used to connect the cover assembly 30 to the floor brush housing 10. Specifically, the first connector 33 and the second connector 35 are positioned on the left and right sides of the cover 31 in the forward direction A, so that the first connector 33 and the second connector 35 can respectively cooperate with the first joint 11 and the second joint 13.

[0063] The first connector 33 is connected to the cover 31. The connection between the first connector 33 and the cover 31 can be either a detachable or a non-detachable connection. A detachable connection includes, but is not limited to, one or more combinations of screw connections and snap-fit ​​connections. A non-detachable connection includes, but is not limited to, one or more combinations of gluing, welding, and sintering. This definition will be used for subsequent detachable and non-detachable connections without further elaboration. Similarly, the second connector 35 is connected to the cover 31 in either a detachable or non-detachable manner.

[0064] When the first connector 33 engages with the first joint 11 and the second connector 35 engages with the second joint 13, the cover assembly 30 and the floor brush housing 10 are assembled; when the first connector 33 disengages from the first joint 11 and the second connector 35 disengages from the second joint 13, the cover assembly 30 and the floor brush housing 10 can be disassembled from each other.

[0065] The mating structure 37 is a structure in the cover assembly 30 used to mate with the limiting structure 15 to strengthen the bond strength between the cover assembly 30 and the floor brush housing 10. In the forward direction A of the floor brush device 100, a distance from the operating... Figure 1From the operator's perspective, when viewing the floor brush device 100 from left to right, the direction in which the cover assembly 30 rotates clockwise relative to the floor brush housing 10 is the first direction X1, and the direction in which the cover assembly 30 rotates counterclockwise relative to the floor brush housing 10 is the second direction X2. The first direction X1 and the second direction X2 are opposite. When the mating structure 37 and the limiting structure 15 are engaged, the rotation of the cover assembly 30 relative to the floor brush housing 10 around the first axis L in both the first direction X1 and the second direction X2 is restricted. The first axis L is the axis of rotation of the cover assembly 30 relative to the floor brush housing 10. The line connecting the first connecting member 33 and the second connecting member 35 is parallel to the first axis L, and the first axis L is parallel to the axis of rotation of the cleaning component 20. At this time, the bonding strength between the cover assembly 30 and the floor brush housing 10 is high, and the cover assembly 30 is not prone to shaking during the use of the cleaning equipment 1000 and / or the floor brush device 100.

[0066] In the floor brush device 100 of the cleaning equipment 1000 of this application, the first connecting member 33 of the cover assembly 30 cooperates with the first joint portion 11 of the floor brush housing 10, and the second connecting member 35 of the cover assembly 30 cooperates with the second joint portion 13 of the floor brush housing 10, so that the cover assembly 30 is mounted on the floor brush housing 10. At this time, the mating structure 37 cooperates with the limiting structure 15 to restrict the rotation of the cover assembly 30 about a axis parallel to the first axis L, thereby strengthening the connection between the cover assembly 30 and the floor brush housing 10. Therefore, the cover assembly 30 can be stably mounted on the floor brush housing 10, and the floor brush device 100 has good structural stability and high structural strength. During the cleaning process of the cleaning equipment 1000 cleaning the surface to be cleaned or the cleaning equipment 1000 self-cleaning the cleaning component 20, the bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning component 20 has a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning component 20, and the cleaning component 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0067] Please refer to Figures 3 to 5In some embodiments, the limiting structure 15 includes a first limiting portion 151, and the mating structure 37 includes a first mating portion 371. The floor brush housing 10 has a front portion and a rear portion, and the forward direction A is from the rear portion to the front portion. The front portion is the part of the floor brush housing 10 that is forward in the forward direction A of the floor brush device 100 cleaning, and the rear portion is the part of the floor brush housing 10 that is rearward in the forward direction A of the floor brush device 100 cleaning. It should be noted that the "front portion" and "rear portion" of other components in this document are also viewed in the forward direction A. The part that is forward in the forward direction A is the "front portion" of the component, and the part that is rearward in the forward direction A is the "rear portion" of the component. For example, the "front portion of the bracket 17" and the "front portion of the cover 31" mentioned below can be understood in this way. The first limiting portion 151 is provided at the front portion of the floor brush housing 10, and the first mating portion 371 is located on the side of the cover 31 near the floor brush housing 10. The first mating part 371 is supported on the first limiting part 151 and cooperates with the first limiting part 151 to restrict the cover assembly 30 from rotating about the first axis L in the first direction X1.

[0068] Specifically, in the above embodiment, the first limiting part 151 in the limiting structure 15 and the first mating part 371 in the mating structure 37 are configured to cooperate with each other to jointly restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the first direction X1.

[0069] The first limiting part 151 is positioned at the front of the brush housing 10, and the corresponding first mating part 371 is positioned on the cover assembly 30 near the brush housing 10. When the first connecting member 33 and the second connecting member 35 engage with the first connecting part 11 and the second connecting part 13 respectively, so that the cover assembly 30 and the brush housing 10 are assembled, the first mating part 371 and the first limiting part 151 cooperate with each other, and the first mating part 371 is supported on the first limiting part 151. At this time, at least a portion of the surface of the first mating part 371 abuts against at least a portion of the surface of the first limiting part 151, and the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L in the first direction X1 is restricted. Therefore, the bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning component 20 exerts greater pressure on the side wall of the cover assembly 30 facing the cleaning component 20, and the cleaning component 20 can effectively clean the cover assembly 30. As a result, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0070] Please refer to Figures 3 to 5In some embodiments, the first limiting portion 151 is a first limiting step 151, and the first limiting step 151 includes at least one first sub-limiting step. The first mating portion 371 includes at least one first sub-matting portion, each first sub-matting portion corresponding one-to-one with each first sub-limiting step, such that each first sub-matting portion is respectively supported on the corresponding first sub-limiting step to restrict the cover assembly 30 from rotating about the first axis L along the first direction X1. Wherein, in the direction from the rear to the front of the floor brush housing 10, the size of the first limiting step 151 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0071] Specifically, in the above embodiment, the first limiting step 151 is a specific structure used to cooperate with the first mating part 371 to jointly restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the first direction X1. The first limiting step 151 includes one or more first sub-limiting steps (not shown). When there is more than one first sub-limiting step, the cooperation between the first limiting part 151 and the first mating part 371 is tighter, and the first limiting part 151 and the first mating part 371 can more reliably restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the first direction X1.

[0072] It can be understood that the first sub-fitting part is a structure that cooperates with the first sub-limiting step. The number, shape and size of the first sub-fitting parts correspond to the number, shape and size of the first sub-limiting steps. When the first connecting piece 33 and the second connecting piece 35 are engaged with the first connecting part 11 and the second connecting part 13 respectively, so that when the cover assembly 30 and the floor brush housing 10 are assembled, each first sub-fitting part cooperates with each first sub-limiting step. The first sub-fitting part is supported on the first sub-limiting step. At this time, at least a part of the surface of the first sub-fitting part abuts against at least a part of the surface of the first sub-limiting step, and the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L in the first direction X1 is restricted.

[0073] When there is one or more first sub-limiting steps and first sub-mates, the surfaces of the first sub-mates and the first sub-limiting steps that abut against each other are non-planar and have a relatively complex shape. At this time, the gap between the cover assembly 30 and the floor brush housing 10 is small and relatively tortuous. Water and other impurities are not easy to pass through the gap between the cover assembly 30 and the floor brush housing 10. The waterproof effect of the floor brush device 100 is good, the normal operation of the internal components of the floor brush device 100 is not affected, the floor brush device 100 can work normally, and has a long service life.

[0074] In the direction from the rear to the front of the brush housing 10, the size of the first limiting step 151 directly affects the stability of the first mating part 371 supported on the first limiting step 151 (first limiting part 151), and thus affects the bonding strength between the cover assembly 30 and the brush housing 10. Therefore, the size of the first limiting step 151 is greater than or equal to 0.5 mm and less than or equal to 5 mm. Specifically, the size of the first limiting step 151 can be, but is not limited to, any one or any two of 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, and 5 mm. If the size of the first limiting step 151 is less than 0.5 mm, then the size of the first limiting step 151 is too small. In this case, the contact area between the first mating part 371 and the first limiting step 151 is too small, and the first mating part 371 cannot be stably supported on the first limiting step 151. The bonding strength between the cover assembly 30 and the floor brush housing 10 is insufficient, and the cover assembly 30 will shake. If the size of the first limiting step 151 is greater than 5 mm, then the size of the first limiting step 151 is too large. In this case, the size of the floor brush housing 10 is too large, which is not conducive to the miniaturization design of the floor brush device 100. The appearance of the floor brush device 100 is affected, and the portability of the floor brush device 100 is insufficient. Therefore, the size of the first limiting step 151 is within the above-mentioned range, which can ensure that the bonding strength between the cover assembly 30 and the floor brush housing 10 is large, the cover assembly 30 will not shake, and the miniaturization requirements of the floor brush device 100 are met.

[0075] Therefore, in the floor brush device 100 of this application, the first sub-limiting step and the first sub-fitting part cooperate with each other to restrict the cover assembly 30 from rotating around the first axis L in the first direction X1. The bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning member 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0076] Please refer to Figures 3 to 5 In some embodiments, the limiting structure 15 includes a second limiting portion 153, and the mating structure 37 includes a second mating portion 373. The floor brush housing 10 also includes a mounting bracket 17, which is mounted on the front of the floor brush housing 10. The second limiting portion 153 is located on the front of the mounting bracket 17, and the second mating portion 373 is located on the side of the cover 31 near the mounting bracket 17. The second mating portion 373 is supported on the second limiting portion 153 and engages with the second limiting portion 153 to restrict the cover assembly 30 from rotating about the first axis L in the second direction X2.

[0077] Specifically, in the above embodiment, the second limiting part 153 in the limiting structure 15 and the second mating part 373 in the mating structure 37 are configured to cooperate with each other to jointly restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the second direction X2. The mounting bracket 17 is a structure in the brush housing 10 for mounting components such as the water outlet structure (not shown) and / or the PI membrane 50 (described below). The mounting bracket 17 is positioned on the front of the brush housing 10. In the direction from the rear to the front of the brush housing 10, the mounting bracket 17 engages with the cover 31 and together forms part of an arc-shaped sidewall that contacts the cleaning component 20. The mounting bracket 17 has a front part and a rear part, and the forward direction A is from the rear to the front. The front part is the portion of the mounting bracket 17 that is forward in the forward direction A of the brush device 100 cleaning, and the rear part is the portion of the mounting bracket 17 that is rearward in the forward direction A of the brush device 100 cleaning.

[0078] The second limiting part 153 is positioned on the front of the mounting bracket 17 on the brush housing 10, and the corresponding second mating part 373 is positioned on the side of the cover 31 near the mounting bracket 17 on the cover assembly 30. When the first connecting member 33 and the second connecting member 35 are engaged with the first connecting part 11 and the second connecting part 13 respectively, so that the cover assembly 30 and the brush housing 10 are assembled, the second mating part 373 and the second limiting part 153 cooperate with each other, and the second mating part 373 is supported on the second limiting part 153. At this time, at least a portion of the surface of the second mating part 373 abuts against at least a portion of the surface of the second limiting part 153. At this time, the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L in the second direction X2 is restricted. Therefore, the bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning component 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning component 20, and the cleaning component 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0079] Please refer to Figure 4 In some embodiments, the floor brush device 100 further includes a water outlet structure and / or a PI membrane 50. The water outlet structure is connected to a water source and is used to supply water to the cleaning component 20. The PI membrane 50 is used to heat or dry the cleaning component 20. The water outlet structure and / or the PI membrane 50 are mounted on a mounting bracket 17.

[0080] Specifically, the water outlet structure is used to supply water to the cleaning component 20, enabling the cleaning component 20 to clean the surface to be cleaned more effectively. The water outlet structure is connected to a water source to supply water. In this application, the water can be, but is not limited to, clean water, a mixture of cleaning agent and clean water, a mixture of disinfectant and clean water, or a mixture of conditioner and clean water, etc., as long as it can be used for cleaning. It should be noted that "clean water" here is only a relative concept; any water that is cleaner than sewage as perceived by the user is within the scope of protection. For example, clean water can be municipal tap water, well water, or clean water from rivers, lakes, or seas. The water source can be a flowing water source, such as a water pump, or a stagnant water source, such as a water tank. The water outlet structure guides the water supplied by the water source to the cleaning component 20, which uses this water to clean the surface to be cleaned. The water outlet structure is installed on the mounting bracket 17 so that at least a portion of the water supplied by the water outlet device can reach the cleaning component 20.

[0081] The PI membrane 50 is a component used for maintaining the cleaning component 20. When energized, the PI membrane 50 generates heat and transfers at least a portion of this heat to the cleaning component 20 for maintenance, such as heating or drying, thus extending its service life. The PI membrane 50 is mounted on a mounting bracket 17 so that at least a portion of the heat generated by the PI membrane 50 can reach the cleaning component 20. In one example, the mounting bracket 17 engages with the cover 31, and together with the PI membrane 50, forms an arc-shaped sidewall that contacts the cleaning component 20. Rotation of the cleaning component 20 removes debris and / or wastewater from the inside of this arc-shaped sidewall.

[0082] In summary, the floor brush device 100 of this application improves the cleaning effect by supplying water to the cleaning component 20 to the floor cleaning surface through the water outlet structure, and / or, the floor brush device 100 of this application heats or dries the cleaning component 20 through the PI membrane 50 to give the cleaning component 20 a longer service life. The mounting bracket 17 provides an installation position for the water outlet structure and / or the PI membrane 50. Therefore, the floor brush device 100 has more powerful functions and can better meet the needs of users.

[0083] Please refer to Figures 3 to 5 In some embodiments, the second limiting portion 153 is a second limiting step 153, and the second limiting step 153 includes at least one second sub-limiting step 1531. The second mating portion 373 includes at least one second sub-matting portion 3731, each second sub-matting portion 3731 corresponding one-to-one with each second sub-limiting step 1531, such that each second sub-matting portion 3731 is respectively supported on the corresponding second sub-limiting step 1531 to restrict the cover assembly 30 from rotating about the first axis L along the second direction X2. Wherein, in the direction from the front to the rear of the floor brush housing 10, the size of the second limiting step 153 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0084] Specifically, in the above embodiment, the second limiting step 153 is a specific structure used to cooperate with the second mating part 373 to jointly restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the second direction X2. The second limiting step 153 includes one or more second sub-limiting steps 1531. When there is more than one second sub-limiting step 1531, the cooperation between the second limiting part 153 and the second mating part 373 is tighter, and the second limiting part 153 and the second mating part 373 can more reliably restrict the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L along the second direction X2.

[0085] It is understood that the second sub-fitting part 3731 is a structure that cooperates with the second sub-limiting step 1531. The number, shape and size of the second sub-fitting part 3731 correspond to the number, shape and size of the second sub-limiting step 1531. When the first connecting member 33 and the second connecting member 35 are engaged with the first connecting part 11 and the second connecting part 13 respectively, so that when the cover assembly 30 and the brush housing 10 are assembled, each second sub-fitting part 3731 cooperates with each second sub-limiting step 1531. The second sub-fitting part 3731 is carried on the second sub-limiting step 1531. At this time, at least a part of the surface of the second sub-fitting part 3731 abuts against at least a part of the surface of the second sub-limiting step 1531, and the rotation of the cover assembly 30 relative to the brush housing 10 about the first axis L in the second direction X2 is restricted.

[0086] When there is one or more second sub-limiting steps 1531 and second sub-fitting parts 3731, the surfaces of the second sub-fitting parts 3731 and the second sub-limiting steps 1531 that abut against each other are non-planar and have a relatively complex shape. At this time, the gap between the cover assembly 30 and the floor brush housing 10 is small and relatively tortuous. Water and other impurities are not easy to pass through the gap between the cover assembly 30 and the floor brush housing 10. The waterproof effect of the floor brush device 100 is good, the normal operation of the internal components of the floor brush device 100 is not affected, the floor brush device 100 can work normally, and has a long service life.

[0087] In the direction from the rear to the front of the brush housing 10, the size of the second limiting step 153 directly affects the stability of the second mating part 373 supported on the second limiting step 153 (second limiting part 153), and thus affects the bonding strength between the cover assembly 30 and the brush housing 10. Therefore, the size of the second limiting step 153 is greater than or equal to 0.5 mm and less than or equal to 5 mm. Specifically, the size of the second limiting step 153 can be, but is not limited to, any one or any two of 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, and 5 mm. If the size of the second limiting step 153 is less than 0.5 mm, then the size of the second limiting step 153 is too small. In this case, the contact area between the second mating part 373 and the second limiting step 153 is too small, and the second mating part 373 cannot be stably supported on the second limiting step 153. The bonding strength between the cover assembly 30 and the floor brush housing 10 is insufficient, and the cover assembly 30 will shake. If the size of the second limiting step 153 is greater than 5 mm, then the size of the second limiting step 153 is too large. In this case, the size of the floor brush housing 10 is too large, which is not conducive to the miniaturization design of the floor brush device 100. The appearance of the floor brush device 100 is affected, and the portability of the floor brush device 100 is insufficient. Therefore, the size of the second limiting step 153 is within the above-mentioned range, which can ensure that the bonding strength between the cover assembly 30 and the floor brush housing 10 is large, the cover assembly 30 will not shake, and the miniaturization requirements of the floor brush device 100 are met.

[0088] Therefore, in the floor brush device 100 of this application, the second sub-limiting step 1531 and the second sub-fitting part 3731 cooperate with each other to restrict the cover assembly 30 from rotating around the first axis L in the second direction X2. The bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning member 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0089] Please refer to Figure 1 , Figure 3 and Figure 6In some embodiments, the limiting structure 15 includes a first connecting portion 11 and a second connecting portion 13. The first connecting portion 11 and the second connecting portion 13 are located at the front of the floor brush housing 10. The mating structure 37 includes a third mating portion 375, which is located on either the left or right side of the cover 31 along the forward direction A of the floor brush device 100. Alternatively, the mating structure 37 includes two third mating portions 375, which are located on the left and right sides of the cover 31 along the forward direction A of the floor brush device 100, respectively. The third mating portions 375 abut against the first connecting portion 11 and / or the second connecting portion 13 to restrict the cover assembly 30 from rotating about the first axis L along the first direction X1 and the second direction X2.

[0090] Specifically, in the above embodiment, the first joint 11 and the second joint 13 can serve as a limiting structure 15 to cooperate with the mating structure 37. In this case, the mating structure 37 that cooperates with the first joint 11 and the second joint 13 is the third mating part 375.

[0091] In some examples, there is only one third mating part 375. In this case, the third mating part 375 is located on the cover 31, specifically on either the left or right side of the cover 31 along the forward cleaning direction A of the floor brush device 100. The third mating part 375 engages with one of the first mating parts 11 and the second mating part 13 located on the same side along the forward cleaning direction A of the floor brush device 100. The third mating part 375 abuts against the first mating part 11 or the second mating part 13 on the same side, thereby restricting the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L along the first direction X1 and the second direction X2.

[0092] In other examples, there are two third mating parts 375. In this case, the third mating parts 375 are located on the cover 31, specifically on the left and right sides of the cover 31 along the forward cleaning direction A of the floor brush device 100. Each of the two third mating parts 375 engages with one of the first connecting parts 11 or the second connecting part 13 located on the same side along the forward cleaning direction A of the floor brush device 100. Each third mating part 375 abuts against the first connecting part 11 or the second connecting part 13 on the same side, thereby better restricting the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L along the first direction X1 and the second direction X2.

[0093] Therefore, when the third mating part 375 is in contact with the first mating part 11 and / or the second mating part 13, the bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning member 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0094] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, in the forward cleaning direction A of the floor brush device 100, the third mating part 375 is closer to the front of the cover 31 than the first connecting member 33. Specifically, taking the forward cleaning direction A of the floor brush device 100 as a reference, the first connecting member 33 and the third mating part 375 are sequentially distributed in the direction from the rear to the front of the floor brush housing 10. The third mating part 375 is closer to the front of the cover 31 than the first connecting member 33, which allows the user to more easily operate the first connecting member 33 and the cover 31 simultaneously during the installation or removal of the cover assembly 30 and the floor brush housing 10.

[0095] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, in the forward cleaning direction A of the floor brush device 100, the third mating portion 375 is closer to the front of the cover 31 than the first mating portion 11. Specifically, taking the forward cleaning direction A of the floor brush device 100 as a reference, the first mating portion 11 and the third mating portion 375 are sequentially distributed in the direction from the rear to the front of the floor brush housing 10. The third mating portion 375 is closer to the front of the cover 31 than the first mating portion 11, which allows the user to more easily move the operating body 31 closer to or further away from the floor brush housing 10 during the installation or removal of the cover assembly 30 and the floor brush housing 10.

[0096] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, the first connecting portion 11 and the second connecting portion 13 include a first abutting surface 111 disposed at the front of the floor brush housing 10, and the third mating portion 375 includes a second abutting surface 3751 facing the first abutting surface 111. When the third mating portion 375 abuts against the first connecting portion 11 and / or the second connecting portion 13, the first abutting surface 111 and the second abutting surface 3751 abut against each other to restrict the cover assembly 30 from rotating about the first axis L along the first direction X1 and the second direction X2.

[0097] Specifically, the first abutting surface 111 is the plane on which the first joint portion 11 and / or the second joint portion 13 abuts against the third mating portion 375. The first abutting surface 111 is the outer surface of the first joint portion 11 and the second joint portion 13 located at the front of the brush housing 10, specifically, the outer surface of the front of the brush housing 10 opposite to the cover 31. The second abutting surface 3751 is the surface in the third mating portion 375 that abuts against the first abutting surface 111, and the second abutting surface 3751 is the outer surface of the third mating portion 375 opposite to the front of the brush housing 10.

[0098] When the first connector 33 and the second connector 35 engage with the first joint 11 and the second joint 13 respectively, so that the cover assembly 30 and the floor brush housing 10 are assembled, the third mating part 375 abuts against the first joint 11 and / or the second joint 13. At this time, the first abutting surface 111 abuts against the second abutting surface 3751. Therefore, the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L in the first direction X1 and the second direction X2 is restricted.

[0099] Therefore, in the floor brush device 100 of this application, the first abutting surface 111 and the second abutting surface 3751 abut against each other to restrict the cover assembly 30 from rotating around the first axis L in the first direction X1 and the second direction X2. The bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, and the cover assembly 30 will not shake. The cleaning member 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0100] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, when the floor brush device 100 is placed on the surface to be cleaned, the angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 is greater than or equal to 5° and less than or equal to 35°.

[0101] Specifically, when the floor brush device 100 is placed on a horizontal surface to be cleaned and is in normal use, the height direction H of the floor brush device 100 is perpendicular to the surface to be cleaned. When the first abutting surface 111 and the second abutting surface 3751 are in contact with each other, the angle θ between the first abutting surface 111 and the height direction H of the floor brush device 100 is the same as the angle θ between the second abutting surface 3751 and the height direction H of the floor brush device 100. This angle θ will directly affect the effect of the third mating part 375 and the first connecting part 11 and / or the second connecting part 13 in restricting the cover assembly 30 from rotating around the first axis L in the first direction X1 and the second direction X2.

[0102] Please refer to Figure 6 The angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 can be, but is not limited to, any one or any two of 5°, 8°, 11°, 14°, 17°, 20°, 23°, 26°, 29° and 35°. If the angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 is less than 5°, then the angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 is too small. In this case, when the cover assembly 30 rotates around the first axis L along the second direction X2, the third mating part 375 is easy to separate from the first joint part 11 and / or the second joint part 13, resulting in poor contact effect. The bonding strength between the cover assembly 30 and the floor brush housing 10 is insufficient, and the cover assembly 30 will shake. If the angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 is greater than 35°, then the angle θ is too large. In this case, the dimensions of the third mating part 375, the first joint part 11, and / or the second joint part 13 are large, resulting in an excessively large floor brush housing 10. This is detrimental to the miniaturization design of the floor brush device 100, affecting its aesthetic appearance and portability. Therefore, the angle θ between the first contact surface 111 and the height direction H of the floor brush device 100 is within the aforementioned range. This ensures a strong bond between the cover assembly 30 and the floor brush housing 10, preventing the cover assembly 30 from shaking, while also meeting the miniaturization requirements of the floor brush device 100.

[0103] Please refer to Figures 1 to 3 In some embodiments, the limiting structure 15 includes a groove 155, and the mating structure 37 includes a fourth mating portion 377. The groove 155 is disposed on the first mating portion 11 or the second mating portion 13, and the fourth mating portion 377 extends into the groove 155 and engages with the groove 155 to restrict the cover assembly 30 from rotating about the first axis L along the first direction X1 and the second direction X2.

[0104] Specifically, the fourth mating part 377 is a specific structure used to mate with the groove 155 to realize the mating structure 37 and the limiting structure 15. The groove 155 is formed on the first joint 11 or the second joint 13, and correspondingly, the fourth mating part 377 is provided on the cover 31 near the first joint 11 or the second joint 13, and with the forward direction A of the floor brush device 100 cleaning as a reference, the groove 155 and the fourth mating part 377 are located on the same side. The outer contour dimensions and shape of the fourth mating part 377 are respectively matched with the inner contour dimensions and shape of the groove 155.

[0105] When the first connector 33 and the second connector 35 engage with the first joint 11 and the second joint 13 respectively, so that the cover assembly 30 and the floor brush housing 10 are assembled, at least a portion of the fourth mating portion 377 extends into the corresponding groove 155. At this time, the fourth mating portion 377 and the groove 155 cooperate with each other, and at least a portion of the outer side wall of the fourth mating portion 377 abuts against at least a portion of the inner side wall of the groove 155. Therefore, the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L in the first direction X1 and the rotation in the second direction X2 are restricted.

[0106] Therefore, in the floor brush device 100 of this application, the fourth mating part 377 cooperates with the groove 155 to restrict the cover assembly 30 from rotating around the first axis L along the first direction X1 and the second direction X2. The bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning member 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0107] Please refer to Figures 1 to 3 In some embodiments, the limiting structure 15 includes two grooves 155, and the mating structure 37 includes two fourth mating portions 377. The grooves 155 are provided on the first mating portion 11 and the second mating portion 13, and the two fourth mating portions 377 extend into the two grooves 155 respectively and mate with the two grooves 155 respectively to restrict the cover assembly 30 from rotating about the first axis L along the first direction X1 and the second direction X2.

[0108] Specifically, in the above embodiment, there are two grooves 155, which are respectively opened on the first joint 11 and the second joint 13. There are also two fourth mating parts 377, which are respectively arranged on the left and right sides of the forward direction A of the floor brush device 100 cleaning. Taking the forward direction A of the floor brush device 100 cleaning as a reference, each fourth mating part 377 is respectively mated with the groove 155 located on the same side.

[0109] When the first connector 33 and the second connector 35 engage with the first joint 11 and the second joint 13 respectively, so that the cover assembly 30 and the floor brush housing 10 are assembled, at least a portion of each fourth mating part 377 extends into each groove 155. At this time, the fourth mating part 377 and the corresponding groove 155 cooperate with each other, and at least a portion of the outer side wall of the fourth mating part 377 abuts against at least a portion of the inner side wall of the groove 155. Therefore, the rotation of the cover assembly 30 relative to the floor brush housing 10 about the first axis L in the first direction X1 and the rotation in the second direction X2 are better restricted.

[0110] Therefore, in the floor brush device 100 of this application, the two fourth mating parts 377 and the two grooves 155 respectively cooperate with each other to restrict the cover assembly 30 from rotating around the first axis L along the first direction X1 and the second direction X2, and at this time the cover assembly 30 is in force balance. The bonding strength between the cover assembly 30 and the floor brush housing 10 is large, the cover assembly 30 will not shake, the cleaning member 20 has a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, the cleaning member 20 can effectively clean the cover assembly 30, so the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0111] Please refer to Figures 1 to 3 In some embodiments, when the floor brush device 100 is placed on the surface to be cleaned, the included angle Φ between the height direction H of the floor brush device 100 and the insertion direction of the insertion groove 155 of the fourth mating part 377 is greater than or equal to 5° and less than or equal to 30°.

[0112] Specifically, when the fourth mating part 377 is inserted into the groove 155, the insertion direction of the fourth mating part 377 into the groove 155 will directly affect the effect of the third mating part 375 and the groove 155 in restricting the cover assembly 30 from rotating around the first axis L along the first direction X1 and the second direction X2.

[0113] Please refer to Figure 3The angle Φ between the height direction H of the floor brush device 100 and the insertion direction of the fourth mating part 377 into the groove 155 can be, but is not limited to, any one or any two of 5°, 8°, 11°, 14°, 17°, 20°, 23°, 26°, 28°, and 30°. If the angle Φ between the height direction H of the floor brush device 100 and the insertion direction of the fourth mating part 377 into the groove 155 is less than 5°, then the inclination of the insertion direction of the fourth mating part 377 into the groove 155 is too small. In this case, when the cover assembly 30 rotates around the first axis L along the second direction X2, the third mating part 375 is easily separated from the first joint part 11 and / or the second joint part 13, resulting in poor contact effect. The bonding strength between the cover assembly 30 and the floor brush housing 10 is insufficient, and the cover assembly 30 will shake. If the angle Φ between the height direction H of the floor brush device 100 and the insertion direction of the fourth mating part 377 into the groove 155 is greater than 35°, the insertion direction of the fourth mating part 377 into the groove 155 will be too tilted. In this case, the process of inserting the fourth mating part 377 into the groove 155 will be difficult and prone to jamming, resulting in poor smoothness for the user in assembling or disassembling the cover assembly 30 and the floor brush housing 10. Therefore, the angle Φ between the height direction H of the floor brush device 100 and the insertion direction of the fourth mating part 377 into the groove 155 should be within the aforementioned range. This ensures a strong bond between the cover assembly 30 and the floor brush housing 10, preventing the cover assembly 30 from shaking, while also allowing the user to easily assemble or disassemble the cover assembly 30 and the floor brush housing 10.

[0114] Please refer to Figures 1 to 3 and Figure 7 In some embodiments, the first connector 33 and the second connector 35 are movable relative to the cover 31, and the insertion direction of the fourth mating part 377 into the groove 155 is perpendicular to the moving direction of the first connector 33.

[0115] Specifically, to facilitate cleaning of the floor brush device 100, such as cleaning the cleaning component 20 or the cover 31, when the first connecting member 33 and the second connecting member 35 move relative to the cover 31, the first connecting member 33 can disengage from the first connecting portion 11, and the second connecting member 35 can disengage from the second connecting portion 13. At this time, the cover assembly 30 and the floor brush housing 10 can be disassembled from each other. In this application, the moving direction of the first connecting member 33 and the moving direction of the second connecting member 35 are both parallel to the first axis L. The first connecting member 33 and the second connecting member 35 can move in the same direction or move towards each other.

[0116] When the moving direction of the first connector 33 is perpendicular to the insertion direction of the fourth mating part 377 into the groove 155, if the first connector 33 is accidentally touched and moves, since the moving direction of the cover 31 is perpendicular to the insertion direction of the fourth mating part 377 into the groove 155, the fourth mating part 377 is difficult to disengage from the groove 155, and the cover assembly 30 will not separate from the floor brush housing 10. Furthermore, the force exerted on the cover 31 by the first connector 33 and the first connecting part 11 is at an angle to the force exerted on the cover 31 by the fourth mating part 377 into the groove 155. This allows the fourth mating part 377 and the groove 155 to better restrict the rotation of the cover assembly 30 around the first axis L along the first direction X1 and the second direction X2. Therefore, the bonding strength between the cover assembly 30 and the floor brush housing 10 is relatively large, the cover assembly 30 will not shake, the cleaning component 20 exerts a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning component 20, and the cleaning component 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0117] Please refer to Figures 1 to 3 In some embodiments, the first connector 33 and the second connector 35 are movable relative to the cover 31, and the insertion direction of the fourth mating part 377 into the groove 155 is perpendicular to the moving direction of the second connector 35.

[0118] Specifically, to facilitate cleaning of the floor brush device 100, such as cleaning the cleaning component 20 or the cover 31, when the first connecting member 33 and the second connecting member 35 move relative to the cover 31, the first connecting member 33 can disengage from the first connecting portion 11, and the second connecting member 35 can disengage from the second connecting portion 13. At this time, the cover assembly 30 and the floor brush housing 10 can be detached from each other. When the second connecting member 35 moves relative to the second connecting portion 13, the second connecting member 35 may drive the cover 31 connected to it to move in the same direction.

[0119] The force exerted by the second connector 35 on the cover 31 by the second joint 13 is at an angle to the force exerted by the fourth mating part 377 on the cover 31 by the insertion groove 155. The fourth mating part 377 and the groove 155 can better restrict the rotation of the cover assembly 30 around the first axis L along the first direction X1 and the second direction X2. Therefore, the bonding strength between the cover assembly 30 and the floor brush housing 10 is large, the cover assembly 30 will not shake, the cleaning member 20 exerts greater cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0120] Please refer to Figures 1 to 3 In some embodiments, the groove 155 includes a first sub-groove 1551 and a second sub-groove 1553, the first sub-groove 1551 and the second sub-groove 1553 communicating with each other. In the height direction H of the floor brush device 100, the first sub-groove 1551 is closer to the top of the floor brush housing 10 than the second sub-groove 1553. The width of the first sub-groove 1551 is equal to the width of the second sub-groove 1553, or the width of the first sub-groove 1551 is greater than the width of the second sub-groove 1553. The width of the first sub-groove 1551 gradually decreases in the height direction H of the floor brush device 100 towards the second sub-groove 1553.

[0121] Specifically, depending on the inner contour shape of the groove 155, the groove 155 includes a first sub-groove 1551 and a second sub-groove 1553 that are interconnected. When the floor brush device 100 is placed on the surface to be cleaned for normal use, the side of the floor brush housing 10 furthest from the surface to be cleaned in the height direction H is the top of the floor brush housing 10. In the height direction H of the floor brush device 100, in the direction closer to the top of the floor brush housing 10, the second sub-groove 1553 and the first sub-groove 1551 are distributed sequentially, that is, the first sub-groove 1551 is closer to the top of the floor brush housing 10 than the second sub-groove 1553.

[0122] The inner contour shape of the second sub-groove 1553 matches the outer contour shape of the portion of the fourth mating part 377 located within the second sub-groove 1553. At least a portion of the outer sidewall of the fourth mating part 377 abuts against at least a portion of the inner sidewall of the second sub-groove 1553. In the portion where the first sub-groove 1551 and the second sub-groove 1553 communicate, the width of the first sub-groove 1551 is equal to the width of the second sub-groove 1553. In the height direction H of the floor brush device 100, away from the second sub-groove 1553, the width of the first sub-groove 1551 gradually increases. Therefore, the width of the remaining portion of the first sub-groove 1551 is greater than the width of the second sub-groove 1553. Thus, the groove 155 in this application includes a first sub-groove 1551 and a second sub-groove 1553 with different shapes. The fourth mating part 377 first passes through the first sub-groove 1551 and then through the second sub-groove 1553. The width of the first sub-groove 1551 gradually decreases in the height direction H of the floor brush device 100 towards the second sub-groove 1553, so as to guide the fourth mating part 377 to be inserted into the second sub-groove 1553. The inner contour shape of the second sub-groove 1553 matches the outer contour shape of the portion of the fourth mating part 377 located in the second sub-groove 1553. Therefore, the second sub-groove 1553 and the first sub-groove 1551 can cooperate with the fourth mating part 377 to restrict the cover assembly 30 from rotating around the first axis L in the first direction X1 and the second direction X2. At this time, the bonding strength between the cover assembly 30 and the floor brush housing 10 is large, the cover assembly 30 will not shake, the cleaning member 20 has a large cleaning pressure on the side wall of the cover assembly 30 facing the cleaning member 20, and the cleaning member 20 can effectively clean the cover assembly 30. Therefore, the garbage and / or sewage on the inner side wall of the cover assembly 30 can be thoroughly cleaned without producing a foul odor.

[0123] Please refer to Figures 1 to 3In some embodiments, when the first connector 33 and the second connector 35 are engaged with the first connecting portion 11 and the second connecting portion 13 respectively, the cover assembly 30 is assembled with the floor brush housing 10. When the first connector 33 is disengaged from the first connecting portion 11, the cover assembly 30 can rotate about the connection point of the second connector 35 and the second connecting portion 13 to move the cover assembly 30 away from the cleaning component 20, thereby disassembling the cover assembly 30 from the floor brush housing 10. Specifically, as described above, when the first connector 33 is engaged with the first connecting portion 11 and the second connector 35 is engaged with the second connecting portion 13, the cover assembly 30 and the floor brush housing 10 are assembled, and the floor brush device 100 can perform cleaning work. When the first connector 33 is disengaged from the first connecting portion 11, the cover assembly 30 and the floor brush housing 10 are connected via the second connector 35 and the second connecting portion 13. Since the second connector 35 and the second connecting portion 13 can move relative to each other while engaged, the user can operate the cover assembly 30 to rotate relative to the floor brush housing 10 around the connection point of the second connector 35 and the second connecting portion 13. This allows the cover assembly 30 to move away from the cleaning component 20 and the floor brush housing 10, and further disengage the second connector 35 from the second connecting portion 13, thus achieving disassembly between the cover assembly 30 and the floor brush housing 10. Therefore, during the disassembly of the cover assembly 30 from the floor brush housing 10, the user can first disengage the first connector 33 from the first connecting portion 11, and then disengage the second connector 35 from the second connecting portion 13. The disassembly process of the cover assembly 30 from the floor brush housing 10 is simple and quick, providing a better user experience with the floor brush device 100.

[0124] Please refer to Figures 1 to 3 ,and Figure 7In some embodiments, the floor brush device 100 further includes a first elastic member 71 and a second elastic member 73. A first connecting portion 11 and a second connecting portion 13 are located at the front of the floor brush housing 10. The first connecting portion 11 has a first slot 113, and the second connecting portion 13 has a second slot 131. The cover 31 has a first receiving cavity 311 and a second receiving cavity 313 formed on its left and right sides, respectively. The cover 31 has a first through hole 315 connecting the first receiving cavity 311 to the outside and a second through hole 317 connecting the second receiving cavity 313 to the outside, respectively, on its left and right sides. At least a portion of the first elastic member 71 and the first connecting member 33 are accommodated in the first receiving cavity 311, and the opposite ends of the first elastic member 71 are connected to the first connecting member 33 and the cover 31, respectively. At least a portion of the second elastic member 73 and the second connecting member 35 are accommodated in the second receiving cavity 313, and the opposite ends of the second elastic member 73 are connected to the second connecting member 35 and the cover 31, respectively. When the cover assembly 30 is mounted on the brush housing 10, the first connector 33 extends from the first through hole 315 and is received in the first slot 113 to engage with the first coupling 11, and the second connector 35 extends from the second through hole 317 and is received in the second slot 131 to engage with the second coupling 13. When the first connector 33 is forced to retract into the first receiving cavity 311, the first connector 33 disengages from the first coupling 11, the first elastic member 71 is compressed, and an elastic force is provided to return the first connector 33 to its original position where it partially extends from the first through hole 315. When the second connector 35 is forced to retract into the second receiving cavity 313, the second connector 35 disengages from the second coupling 13, the second elastic member 73 is compressed, and an elastic force is provided to return the second connector 35 to its original position where it partially extends from the second through hole 317.

[0125] Specifically, the first elastic element 71 is a device that returns the first connecting member 33 to a portion of the elastic force extending from the first through hole 315. The first elastic element 71 may be, but is not limited to, a combination of one or more springs, leaf springs, and rubber elastic elements. The second elastic element 73 is a device that returns the second connecting member 35 to a portion of the elastic force extending from the second through hole 317. The second elastic element 73 may be, but is not limited to, a combination of one or more springs, leaf springs, and rubber elastic elements. Taking the forward direction A of the floor brush device 100 as a reference, the first connecting part 11 and the second connecting part 13 are respectively provided on the left and right sides of the front part of the floor brush housing 10, and the first connecting member 33 is provided on the left and right sides of the cover 31, with the first connecting part 11 and the first connecting member 33 on the same side, and the second connecting part 13 and the second connecting member 35 on the same side.

[0126] The first slot 113 is a spatial structure formed on the first connecting portion 11 for at least partial engagement with the first connecting member 33. On the side where the first connecting portion 11 and the first connecting member 33 are located, a first receiving cavity 311 is formed inside the cover 31 to accommodate at least a portion of the first elastic member 71 and the first connecting member 33. A first through hole 315 is formed on the side wall of the cover 31 to connect the first receiving cavity 311 to the outside. The first elastic member 71 is housed in the first receiving cavity 311, and the opposite ends of the first elastic member 71 are respectively connected to the first connecting member 33 and the cover 31. The first elastic member 71 and the first connecting member 33 can be detachably or non-detachably connected, and the first elastic member 71 and the cover 31 can also be detachably or non-detachably connected.

[0127] When the cover assembly 30 is mounted on the floor brush housing 10, the first connector 33 is connected to the cover 31 via the first elastic member 71. At least a portion of the first connector 33 is located in the first receiving cavity 311, and at least the remaining portion of the first connector 33 extends from the first through hole 315 and is accommodated in the first slot 113 to achieve engagement between the first connector 33 and the first connecting portion 11. When the first connector 33 is forced to retract into the first receiving cavity 311, the first connector 33 disengages from the first slot 113 to release engagement with the first connecting portion 11. At this time, at least a portion of the first connector 33 moves in the first through hole 315 and away from the first connecting portion 11. At this time, the first elastic member 71 is compressed, and the first elastic member 71 provides an elastic restoring force opposite to the direction of movement of the first connector 33. This elastic force can cause the first connector 33 to return to its original position after the force on the first connector 33 is released, so that it partially extends out of the first through hole 315.

[0128] The second slot 131 is a spatial structure formed on the second connecting portion 13 for at least partial engagement with the second connecting member 35. On the side where the second connecting portion 13 and the second connecting member 35 are located, a second receiving cavity 313 is formed inside the cover 31 to accommodate at least a portion of the second elastic member 73 and the second connecting member 35. A second through hole 317 is formed on the side wall of the cover 31, connecting the second receiving cavity 313 to the outside. The second elastic member 73 is accommodated in the second receiving cavity 313, and the opposite ends of the second elastic member 73 are respectively connected to the second connecting member 35 and the cover 31. The second elastic member 73 and the second connecting member 35 can be detachably or non-detachably connected, and the second elastic member 73 and the cover 31 can also be detachably or non-detachably connected.

[0129] When the cover assembly 30 is mounted on the floor brush housing 10, the second connector 35 is connected to the cover 31 via the second elastic member 73. At least a portion of the second connector 35 is located in the second receiving cavity 313, and at least the remaining portion of the second connector 35 extends out of the second through hole 317 and is accommodated in the second slot 131 to achieve engagement between the second connector 35 and the second connecting portion 13. When the second connector 35 is forced to retract into the second receiving cavity 313, the second connector 35 disengages from the second slot 131 to release engagement with the second connecting portion 13. At this time, at least a portion of the second connector 35 moves in the second through hole 317 and away from the second connecting portion 13. At this time, the second elastic member 73 is compressed, and the second elastic member 73 provides an elastic restoring force opposite to the direction of movement of the second connector 35. This elastic force can cause the second connector 35 to return to its original position after the force on the second connector 35 is released, so that it partially extends out of the second through hole 317.

[0130] In the floor brush device 100 of this application, when the cover assembly 30 is installed on the floor brush housing 10, the first connector 33 extends into the first slot 113 to achieve stable installation of the cover assembly 30 on the floor brush housing 10. When the first connector 33 is subjected to force and retracts into the first receiving cavity 311, the first connector 33 disengages from the first slot 113 to achieve disassembly of the cover assembly 30 from the floor brush housing 10. The first elastic member 71 provides elastic restoring force for the first connector 33 to reset after the force is released, and the second connector 35 is similarly handled. Therefore, the assembly and disassembly of the cover assembly 30 and the floor brush housing 10 are simple and quick, and users can easily and stably install the cover assembly 30 on the floor brush housing 10 or disassemble the cover assembly 30 from the floor brush housing 10, resulting in a better user experience.

[0131] Please refer to Figures 1 to 3 , Figure 7 and Figure 8 In some embodiments, the first connector 33 includes a first body portion 331, a first protrusion 333, and an operating portion 335. The first body portion 331 is housed in a first receiving cavity 311. The opposite ends of the first elastic member 71 are respectively connected to the cover 31 and the first body portion 331. The first protrusion 333 is connected to the first body portion 331 and extends through the first through hole 315. The operating portion 335 is connected to the first body portion 331 and is located above the first protrusion 333. When the cover assembly 30 is mounted on the floor brush housing 10, the first protrusion 333 engages in the first slot 113, and the operating portion 335 is located above the first connecting portion 11.

[0132] Specifically, the first body portion 331 is the main body portion of the first connector 33, and the first body portion 331 is housed in the first receiving cavity 311 to achieve stable installation of the first connector 33 relative to the cover 31. At this time, one end of the first elastic member 71 is connected to the cover 31, and the other end of the first elastic member 71 is connected to the first body portion 331.

[0133] The first protrusion 333 is the part of the first connector 33 that engages with the first slot 113. The first protrusion 333 and the first body 331 can be integrally formed or separately formed. If the first protrusion 333 and the first body 331 are separately formed, they can be detachably connected or non-detachably connected. The first protrusion 333 can protrude from the first through hole 315, and the position of the first protrusion 333 relative to the first through hole 315 is determined by the amount of compression of the first elastic member 71.

[0134] The operating part 335 is a structure in the first connector 33 used for user operation. The operating part 335 and the first body part 331 can be integrally formed or separately formed. When the operating part 335 and the first body part 331 are separately formed, they can be detachably connected or non-detachably connected. The operating part 335 is located above the first protrusion 333 and is always exposed to the outside of the floor brush device 100 so that the user can easily operate the operating part 335.

[0135] When the cover assembly 30 is mounted on the brush housing 10, the first protrusion 333 protrudes from the first through hole 315 and engages in the first slot 113. In the height direction H, the operating part 335 is positioned above the first connecting part 11. When the first connector 33 is forced to retract into the first receiving cavity 311, the first protrusion 333 disengages from the first slot 113, and the operating part 335 moves away from the first connecting part 11. Therefore, by operating the operating part 335, the user can engage or disengage the first protrusion 333 from the first slot 113, and by simultaneously operating the second connector 35 and the second connecting part 13, the user can assemble or disassemble the cover assembly 30 from the brush housing 10. The user can more easily and stably mount the cover assembly 30 onto the brush housing 10, or disassemble the cover assembly 30 from the brush housing 10, resulting in a better user experience.

[0136] Please refer to Figure 1 , Figure 6 and Figure 8In some embodiments, the operating part 335 includes a first guide surface 3351 facing the first connecting part 11, and the first connecting part 11 includes a second guide surface 115 facing the first guide surface 3351. The first guide surface 3351 and the second guide surface 115 are parallel. The angle ψ between the first guide surface 3351 and the plane perpendicular to the height direction H of the floor brush device 100 is greater than or equal to 5° and less than or equal to 30°.

[0137] Specifically, the first guide surface 3351 and the second guide surface 115 are structures that guide the movement of the operating part 335 relative to the first connecting part 11 in a cooperative manner. The first guide surface 3351 is a plane of the operating part 335 facing the outer wall of the first connecting part 11, and the second guide surface 115 is a plane of the first connecting part 11 facing the outer wall of the operating part 335. The first guide surface 3351 and the second guide surface 115 are parallel to achieve a better guiding effect. The angle ψ between the first guide surface 3351 and the plane perpendicular to the height direction H of the floor brush device 100 is the same as the angle ψ between the second guide surface 115 and the plane perpendicular to the height direction H of the floor brush device 100. This angle ψ will directly affect the difficulty of operation and the intuitiveness of observation of the operation process by the user during the operation of the operating part 335.

[0138] Please refer to Figure 6 The angle ψ between the first guide surface 3351 and the plane perpendicular to the height direction H of the floor brush device 100 can be, but is not limited to, any one or any two of 5°, 8°, 11°, 14°, 17°, 20°, 23°, 26°, 28°, and 30°. When the angle ψ takes the above-mentioned range, the cooperation between the first guide surface 3351 and the second guide surface 115 can, to a certain extent, limit the rotation of the cover assembly 30 around the first axis L along the first direction X1. Furthermore, when the user is close to the floor brush device 100 to assemble or disassemble the cover assembly 30 and the floor brush housing 10, the operating angle of the operating part 335 is more compatible with the direction of the force applied by the user's hand, and the user can more clearly and intuitively observe the operation of the first connecting member 33, resulting in a better user experience.

[0139] Please refer to Figures 1 to 3 , Figure 7 and Figure 8 In some embodiments, the second connector 35 includes a second body portion 351 and a second protrusion 353. The second body portion 351 is housed in a second receiving cavity 313, and the opposite ends of the second elastic member 73 are respectively connected to the cover 31 and the second body portion 351. The second protrusion 353 is connected to the second body portion 351 and protrudes through the second through hole 317. When the cover assembly 30 is mounted on the floor brush housing 10, the second protrusion 353 engages in the second slot 131.

[0140] Specifically, the second body portion 351 is the main body portion of the second connector 35, and the second body portion 351 is housed in the second receiving cavity 313 to achieve stable installation of the second connector 35 relative to the cover 31. At this time, one end of the second elastic member 73 is connected to the cover 31, and the other end of the second elastic member 73 is connected to the second body portion 351.

[0141] The second protrusion 353 is a structure for the second connector 35 to engage with the second slot 131. The second protrusion 353 and the second body 351 can be integrally formed or separately formed. If the second protrusion 353 and the second body 351 are separately formed, they can be detachably connected or non-detachably connected. The second protrusion 353 can protrude from the second through hole 317, and the position of the second protrusion 353 relative to the second through hole 317 is determined by the amount of compression of the second elastic member 73.

[0142] When the cover assembly 30 is mounted on the brush housing 10, the second protrusion 353 protrudes from the second through hole 317 and engages in the second slot 131. When the second connector 35 is forced to retract into the second receiving cavity 313, the second protrusion 353 disengages from the second slot 131. Therefore, the user can control the engagement or disengagement of the second protrusion 353 with the second slot 131, and can assemble or disassemble the cover assembly 30 from the brush housing 10 by simultaneously operating the first connector 33 and the first connecting part 11. The user can more easily and stably install the cover assembly 30 on the brush housing 10, or remove the cover assembly 30 from the brush housing 10, resulting in a better user experience.

[0143] Please refer to Figures 1 to 3 In some embodiments, the sum of the dimensions of the contact portion between the cover 31 and the brush housing 10 in the direction from the front to the rear of the brush housing 10 is greater than or equal to 1 mm and less than or equal to 15 mm.

[0144] Specifically, in the direction from the rear to the front of the brush housing 10, the sum of the dimensions of the contact portion between the cover 31 and the brush housing 10 directly affects the stability of the connection between the cover 31 and the brush housing 10, and thus affects the bonding strength between the cover assembly 30 and the brush housing 10. It can be understood that the sum of the dimensions of the contact portion between the cover 31 and the brush housing 10 is at least the sum of the widths of the first limiting step 151 and the second limiting step 153 in the forward direction A. The sum of the dimensions of the contact portion between the cover 31 and the brush housing 10 can be, but is not limited to, any one or any two of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, and 15mm. If the total dimensions of the contact portion between the cover 31 and the brush housing 10 are less than 1 mm, the contact portion is too small. In this case, the contact area between the second mating part 373 and the second limiting step 153 is too small, resulting in insufficient stability of the connection between the cover 31 and the brush housing 10. The bonding strength between the cover assembly 30 and the brush housing 10 is also insufficient, causing the cover assembly 30 to wobble. If the total dimensions of the contact portion between the cover 31 and the brush housing 10 are greater than 15 mm, the contact portion is too large. In this case, the size of the brush housing 10 and / or the cover 31 may be too large, which is detrimental to the miniaturization design of the brush device 100, affecting its aesthetic appearance and portability. Therefore, the sum of the dimensions of the contact portion between the cover 31 and the brush housing 10 is taken within the above-mentioned range, which can make the bonding strength between the cover assembly 30 and the brush housing 10 greater, so that the cover assembly 30 will not wobble, and also enable the brush device 100 to be miniaturized.

[0145] Please refer to Figures 1 to 3 , Figure 9 and Figure 10 In some embodiments, the floor scrubber 100 is applied to a cleaning device 1000, which includes a handle 200, a clean water tank 300, a wastewater tank 400, a suction assembly 500, and a suction pipe. The handle 200 is used to control the movement of the cleaning device 1000. The clean water tank 300 is used to store clean water. The wastewater tank 400 is used to store wastewater and / or garbage. The suction assembly 500 is disposed above the wastewater tank 400. The suction pipe has a suction port. In one example, the cleaning device 1000 is a floor scrubber, and the suction assembly 500 and the suction pipe are respectively connected to the wastewater tank 400. Wastewater and / or garbage are sucked into the wastewater tank 400 through the suction pipe by the suction assembly 500.

[0146] The cleaning device 1000 in this embodiment is a floor scrubber, specifically a handheld floor scrubber. The handle 200 is a structure for the user to hold and control the movement of the cleaning device 1000. The user controls the movement of the cleaning device 1000 by operating the handle 200 to perform a more thorough and comprehensive cleaning of the surface to be cleaned.

[0147] The clean water tank 300 is a structure for storing clean water. The clean water stored in the clean water tank 300 is used in the cleaning process of the cleaning equipment 1000 on the surface to be cleaned and / or in the self-cleaning process of the cleaning equipment 1000. The wastewater tank 400 is a structure for storing wastewater and garbage. After the garbage and / or wastewater enter the wastewater tank 400, most of it is deposited at the bottom of the wastewater tank 400 due to gravity, so that the wastewater and / or garbage can be discharged or manually emptied from the wastewater tank 400 later. The suction pipe (not shown) is used to allow garbage and / or wastewater to enter the wastewater tank 400 through the suction port, that is, the suction pipe establishes a communication channel between the outside and the inside of the wastewater tank 400. The suction assembly 500 draws garbage and / or wastewater into the wastewater tank 400 through the suction port by creating negative pressure in the suction pipe and the wastewater tank 400. The suction assembly 500 is located above the wastewater tank 400.

[0148] When the cleaning equipment 1000 cleans the surface to be cleaned, the cleaning component 20 in the floor brush device 100 cleans the surface and generates some wastewater. The suction component 500 is activated, drawing gas from the wastewater tank 400, thus creating negative pressure in the wastewater tank 400 and the suction pipe. Under this negative pressure, the wastewater and debris on the surface to be cleaned are carried by the gas and enter the wastewater tank 400 through the suction pipe, achieving the cleaning of the surface. Therefore, the cleaning equipment 1000 achieves a good cleaning effect on the surface to be cleaned.

[0149] Please refer to Figure 9 Secondly, the cleaning equipment 1000 of the present application includes the floor brush device 100 described in any of the above embodiments.

[0150] Specifically, in the above embodiments, since the cleaning system 10000 in this application includes a floor brush device 100, it can be understood that the cleaning system 10000 includes at least the same beneficial effects as the floor brush device 100. Therefore, the beneficial effects of the cleaning system 10000 should be referred to the beneficial effects of the floor brush device 100 described above.

[0151] Cleaning equipment 1000 is used to remove stains, dust, debris, or microorganisms to maintain environmental hygiene. Cleaning equipment 1000 can be applied in home, commercial, or industrial settings to perform cleaning tasks on surfaces. Cleaning equipment 1000 can be, but is not limited to, handheld floor scrubbers, carpet cleaners, handheld vacuum cleaners, or handheld floor polishers. The floor brush device 100 is a device within cleaning equipment 1000 used to install cleaning components 20 and other elements for cleaning the surface. It contacts the surface with a large contact area and applies a certain amount of pressure to clean it, thus achieving a good cleaning effect.

[0152] Please refer to Figure 10 Thirdly, the cleaning system 10000 of the present application includes the cleaning equipment 1000 and base station 3000 described in any of the above embodiments. The base station 3000 is used to maintain the cleaning equipment 1000, and / or, the base station 3000 includes a docking position 3100 for docking the cleaning equipment 1000.

[0153] Specifically, in the above embodiments, since the cleaning system 10000 in this application includes a floor brush device 100 and a cleaning device 1000, it is understood that the cleaning system 10000 includes at least the same beneficial effects as the floor brush device 100 and the cleaning device 1000. Therefore, the beneficial effects of the cleaning system 10000 should also refer to the beneficial effects of the floor brush device 100 described above. The base station 3000 is used in conjunction with the cleaning device 1000. After the cleaning device 1000 cleans the surface to be cleaned, it discharges the solid-liquid mixture of garbage, sewage, etc., into the base station 3000. In addition, the base station 3000 can also be used to maintain the cleaning device 1000. For example, the base station 3000 can provide a docking position 3100 for the cleaning device 1000, discharge sewage from the cleaning device 1000, charge the cleaning device 1000, clean or maintain at least part of the structure of the cleaning device 1000, and replenish clean water to the cleaning device 1000.

[0154] Here, we again use cleaning equipment 1000 as an example, specifically a floor scrubber. After the floor scrubber completes cleaning the surface to be cleaned, it can dock at docking position 3100 of base station 3000. Docking position 3100 is a location within base station 3000 used to cooperate with the floor scrubber, allowing it to stably dock on base station 3000 for the discharge of garbage and / or wastewater, as well as for maintenance processes. When the floor scrubber is docked at docking position 3100, maintenance performed by base station 3000 on the floor scrubber includes, but is not limited to: emptying wastewater tank 400, charging the floor scrubber, cleaning or maintaining at least some structural components of the floor scrubber (such as cleaning component 20), and replenishing cleaning fluid to the floor scrubber. At this time, the cooperation between the base station 3000 and the cleaning equipment 1000 (i.e., the floor scrubber) enables the floor scrubber to perform cleaning operations better and ensures that the cleaning equipment 1000 can work normally. At the same time, the maintenance process of the cleaning equipment 1000 makes it less prone to damage and aging, thus giving the cleaning equipment 1000 a longer service life.

[0155] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0156] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
