Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a floor brush structure and cleaning equipment. Background Technology

[0002] A floor scrubber is a cleaning device that integrates floor scrubbing, drying, and wastewater recycling. It is characterized by high efficiency, convenience, and good cleaning effect.

[0003] In related technologies, floor scrubbers include a floor brush, a suction unit, and a wastewater tank. The floor brush rolls on the surface to be cleaned, separating dirt from the floor through physical friction. Simultaneously, the suction unit generates negative pressure, drawing dirt from the surface into the wastewater tank. The floor brush, as the component in direct contact with the surface, requires frequent cleaning to maintain its cleaning effectiveness.

[0004] However, when cleaning the floor brush, liquid can easily seep into the interior through the gaps in the brush housing, causing damage to the internal electronic components. Utility Model Content

[0005] This application provides a floor brush structure and cleaning device to solve the problem that when cleaning a floor brush, liquid enters the interior through the gaps in the brush housing, causing damage to the internal electronic components.

[0006] Firstly, the floor brush structure provided in this application includes:

[0007] The housing has a first limiting part provided on it;

[0008] A driving component is mounted on the housing and has a second limiting part. The driving component is configured to drive the roller brush to roll on the surface to be cleaned.

[0009] The first seal, the first limiting part, and the second limiting part are used together to confine the first seal between the housing and the drive member.

[0010] In this way, the first seal fills the assembly gap between the drive component and the housing, preventing liquid from entering the housing through the assembly gap and damaging the electronic components inside. Furthermore, the first seal is limited by a first limiting part on the housing and a second limiting part on the drive component to prevent displacement of the first seal due to vibration, pressure, etc., which could lead to seal failure and ensure the stability of the first seal installation.

[0011] In one possible implementation, the floor brush structure provided in this application has a housing comprising a first housing portion and a second housing portion connected to each other, a driving member disposed between the first housing portion and the second housing portion, and a first limiting portion provided on at least one of the first housing portion and the second housing portion.

[0012] A second seal is provided between the first housing part and the second housing part.

[0013] Thus, by providing a second seal between the first housing part and the second housing part, the second seal fills the assembly gap between the first housing part and the second housing part, which can prevent liquid from entering the housing through the assembly gap during the operation of the floor brush structure or when cleaning the floor brush structure.

[0014] In one possible implementation, the floor brush structure provided in this application has a stop groove on one of the first housing part and the second housing part, and a matching stop rib on the other.

[0015] The second seal is disposed in the groove of the stop, and the stop rib is inserted into the groove of the stop, and the stop rib abuts against the second seal.

[0016] Thus, the rib is inserted into the groove, and under external pressure, the second seal expands, thereby better sealing the assembly gap between the first and second housing parts and preventing external liquid from entering the housing. Furthermore, the rib and groove form a limiting space, confining the second seal between the first and second housing parts, thus preventing displacement of the second seal due to vibration, pressure, etc., which could lead to seal failure.

[0017] In one possible implementation, the floor brush structure provided in this application has a first sealing element and a driving element that are integrally molded with injection molding.

[0018] In this way, the first seal and the drive component are integrally molded to simplify subsequent installation procedures and facilitate the overall installation of the brush structure.

[0019] In one possible implementation, the floor brush structure provided in this application has a first limiting part that is a first limiting rib facing the drive member, and a second limiting part that is a second limiting rib facing the housing.

[0020] Both the first limiting part and the second limiting part abut against the first sealing element.

[0021] Thus, a limiting space is formed between the first limiting rib and the second limiting rib to limit the first sealing member between the housing and the drive member.

[0022] In one possible implementation, the floor brush structure provided in this application includes a first sealing part and a second sealing part connected to each other, with an angle between the extending direction of the first sealing part and the extending direction of the second sealing part.

[0023] The end of either the first limiting part or the second limiting part abuts against the first sealing part.

[0024] Thus, the first sealing part and the second sealing part intersect to form an L-shaped structure. The included angle of the L-shaped structure abuts against the end of the first limiting part or the end of the second limiting part. This restricts the movement of the first sealing element from the extension direction of the first sealing part and also restricts the movement of the first sealing element from the extension direction of the second sealing part, thereby ensuring the stability of the first sealing element installation.

[0025] In one possible implementation, the floor brush structure provided in this application further includes an extension portion as the first sealing member. The first sealing member, the second sealing member, and the extension portion are connected in sequence. The end of the second limiting member abuts against the first sealing member. The extension portion is provided with a first positioning groove, and the end of the first limiting member is inserted into the first positioning groove.

[0026] Thus, during installation, the first sealing element can be connected to the end of the first limiting part through the first positioning groove on the extension, so as to ensure that the first sealing part and the second sealing part of the first sealing element are installed in the limiting space formed by the first limiting part and the second limiting part, thereby avoiding misalignment and affecting the sealing effect.

[0027] In one possible implementation, the floor brush structure provided in this application has a first positioning part on the extension, the first positioning part and the first positioning groove being disposed opposite to each other on both sides of the extension, and a second positioning part on the drive member, the first positioning part and the second positioning part being connected accordingly.

[0028] In this way, the first positioning part and the second positioning part can play the role of positioning and installation, so that the first seal is installed on the drive member accordingly, and the first sealing part and the second sealing part of the first seal are installed in the limiting space formed by the first limiting part and the second limiting part.

[0029] In one possible implementation, the floor brush structure provided in this application has one of the first positioning part and the second positioning part as a positioning protrusion and the other as a matching second positioning groove.

[0030] Thus, the positioning protrusions are inserted into the corresponding second positioning slots to achieve the positioning function.

[0031] Secondly, the cleaning equipment provided in this application includes a device body and any of the above-mentioned floor brush structures disposed on the device body.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0054] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0055] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0056] In related technologies, floor scrubbers include a floor brush, a suction unit, and a wastewater tank. The floor brush rolls on the surface to be cleaned, separating dirt from the floor through physical friction. Simultaneously, the suction unit generates negative pressure, drawing dirt from the surface into the wastewater tank. The floor brush, as the component in direct contact with the surface, requires frequent cleaning to maintain its cleaning effectiveness.

[0057] However, when cleaning the floor brush, liquid can easily seep into the interior through the gaps in the brush housing, causing damage to the internal electronic components.

[0058] For example, a floor brush includes a housing, a roller brush, and a drive assembly. The drive assembly is housed within the housing, which has a clearance notch. The drive assembly is positioned close to the clearance notch, and its output shaft extends out of the housing through the clearance notch. The roller brush is connected to the output shaft of the drive assembly, allowing the drive assembly to rotate the roller brush. However, a gap exists between the drive assembly (specifically, the gearbox within the drive assembly) and the clearance notch in the housing. This gap allows liquid to enter the interior of the floor brush housing during cleaning.

[0059] In view of the above problems, this application provides a floor brush structure and cleaning device. The floor brush structure includes a housing, a drive member, and a first seal. A first limiting part is provided on the housing, the drive member is disposed on the housing, and a second limiting part is provided on the drive member. The drive member is configured to drive the roller brush to roll on the surface to be cleaned. The first limiting part and the second limiting part are used to jointly restrict the first seal between the housing and the drive member. The first seal fills the assembly gap between the drive member and the housing, thereby preventing liquid from entering the housing through the assembly gap and causing damage to the electronic components inside the housing. Furthermore, the first seal is limited by the first limiting part on the housing and the second limiting part on the drive member to prevent the first seal from shifting due to vibration, pressure, etc., which would lead to seal failure and ensure the stability of the first seal installation.

[0060] The following describes in detail the specific implementation of the floor brush structure and cleaning equipment provided in the embodiments of this application, with reference to the accompanying drawings.

[0061] Reference Figures 1 to 12 As shown, the floor brush structure provided in this application includes a housing 100, a drive component 200, and a first sealing component 300.

[0062] A first limiting part 101 is provided on the housing 100, a driving member 200 is provided on the housing 100, and a second limiting part 210 is provided on the driving member 200. The driving member 200 is configured to drive the roller brush to roll on the surface to be cleaned. The first limiting part 101 and the second limiting part 210 are used to jointly restrict the first sealing member 300 between the housing 100 and the driving member 200.

[0063] It should be noted that the floor brush structure provided in this application embodiment can be used in cleaning equipment, which can be a handheld cleaning device, such as a handheld floor scrubber. The cleaning equipment can be used to clean the surface to be cleaned; for example, it can perform dry or wet cleaning depending on the surface. Alternatively, the cleaning equipment can also be a floor scrubbing robot or any other cleaning equipment with a liquid waste chamber. This application embodiment uses a floor scrubber as an example for illustration.

[0064] Furthermore, the floor brush structure also includes a roller brush (not shown in the figure). The housing 100 has a mounting cavity, and a clearance notch is provided on one side of the housing 100. The drive unit 200 is disposed within the mounting cavity, and its output end extends out of the mounting cavity through the clearance notch. One end of the roller brush is connected to the output end of the drive unit 200, and the other end of the roller brush is rotatably connected to the housing 100, or suspended in the air. This allows the drive unit 200 to rotate the roller brush to clean the surface to be cleaned.

[0065] Reference Figure 2 , Figure 3 and Figure 5 As shown, a first seal 300 is provided between the drive component 200 and the housing 100 through the clearance notch. The first seal 300 fills the assembly gap between the drive component 200 and the housing 100. This can prevent liquid from entering the mounting cavity of the housing 100 through the assembly gap during the operation of the floor brush structure or when cleaning the floor brush structure, which could damage the electronic components in the mounting cavity.

[0066] Furthermore, the housing 100 is provided with a first limiting part 101, and the driving member 200 is provided with a second limiting part 210. The first limiting part 101 and the second limiting part 210 together restrict the first sealing member 300 between the housing 100 and the driving member 200. This can firmly fix the first sealing member 300 within the preset sealing area, preventing the first sealing member 300 from shifting due to vibration, pressure, etc., which would lead to sealing failure. In addition, the first limiting part 101 and the second limiting part 210 can also play a positioning role to ensure that the first sealing member 300 is installed in the designated position.

[0067] The first limiting part 101 and the second limiting part 210 are both interference fit with the first sealing member 300. The interference fit will cause the first limiting part 101 and the second limiting part 210 to exert slight pressure on the first sealing member 300, directly filling the tiny gap that may exist between the housing 100 and the driving member 200, structurally blocking the channel for fluid (liquid or gas) leakage, and greatly improving the sealing performance.

[0068] For example, the first sealing element 300 can be a silicone element, a rubber element, or other sealing material with a certain degree of elasticity. This application embodiment does not specifically limit this.

[0069] It is understandable that the drive component 200 can be conventional existing technology, such as including a drive motor, a gearbox, and a rotating shaft. Both the drive motor and the gearbox are housed within the mounting cavity of the housing 100. The output end of the drive motor is connected to the gearbox, and the rotating shaft is connected to the output shaft of the gearbox via a clearance notch in the housing 100. The roller brush is connected to the rotating shaft. The gearbox serves to reduce the rotational speed and increase the torque to meet the power requirements of the roller brush when cleaning the surface to be cleaned. Specifically, refer to... Figure 1 As shown, the second limiting part 210 is disposed on the gearbox, and the first sealing member 300 is disposed between the gearbox and the housing 100.

[0070] In summary, the floor brush structure provided in this application embodiment fills the assembly gap between the drive member 200 and the housing 100 with the first sealing member 300, thereby preventing liquid from entering the housing 100 through the assembly gap and causing damage to the electronic components inside the housing 100. Furthermore, the first sealing member 300 is limited by the first limiting part 101 on the housing 100 and the second limiting part 210 on the drive member 200 to prevent the first sealing member 300 from shifting due to vibration, pressure, etc., leading to sealing failure and ensuring the stability of the first sealing member 300 installation.

[0071] Reference Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the housing 100 includes a first housing portion 110 and a second housing portion 120 connected to each other, a driving member 200 is disposed between the first housing portion 110 and the second housing portion 120, and a first limiting portion 101 is provided on at least one of the first housing portion 110 and the second housing portion 120. A second sealing member 400 is provided between the first housing portion 110 and the second housing portion 120.

[0072] The first housing portion 110 and the second housing portion 120 are detachably connected to form a mounting cavity.

[0073] In this way, by providing a second seal 400 between the first housing part 110 and the second housing part 120, the second seal 400 seals and fills the assembly gap between the first housing part 110 and the second housing part 120, thus preventing liquid from entering the mounting cavity of the housing 100 through the assembly gap during the operation of the floor brush structure or when cleaning the floor brush structure, which could lead to damage to the electronic components in the mounting cavity.

[0074] The first housing part 110 and the second housing part 120 can be detachably connected by bolt structure, snap-fit ​​structure, etc., which facilitates later maintenance and replacement.

[0075] For example, the second seal 400 can be a silicone part, a rubber part, or other sealing material with a certain elasticity. This application embodiment does not specifically limit this.

[0076] It is understood that at least one of the first housing portion 110 and the second housing portion 120 is provided with the first limiting portion 101. This can be provided on the first housing portion 110, the second housing portion 120, or both the first housing portion 110 and the second housing portion 120. This application does not impose specific limitations on this.

[0077] Preferred, refer to Figure 2 As shown, both the first limiting part 101 and the second limiting part 210 are annular parts. The first limiting part 101 extends from the first housing part 110 to the second housing part 120. The second limiting part 210 is arranged around the periphery of the driving member 200. The first sealing member 300 is a sealing ring, so as to ensure the sealing performance between the housing 100 and the driving member 200.

[0078] In some embodiments, one of the first housing portion 110 and the second housing portion 120 is provided with a stop groove 130, and the other is provided with a matching stop rib 140.

[0079] The second sealing element 400 is disposed in the stop groove 130, and the stop rib 140 is inserted in the stop groove 130, and the stop rib 140 abuts against the second sealing element 400.

[0080] In this way, the stop rib 140 is inserted into the stop groove 130. Under the external clamping force, the second seal 400 expands, thereby better sealing the assembly gap between the first housing part 110 and the second housing part 120 and preventing external liquid from entering the housing 100. Furthermore, the stop rib 140 and the stop groove 130 form a limiting space 211, which restricts the second seal 400 between the first housing part 110 and the second housing part 120, thereby preventing the second seal 400 from shifting due to vibration, pressure, etc., which could lead to seal failure.

[0081] The stop groove 130 and the stop rib 140 are both annular structures, and the second seal 400 is a sealing ring, thus ensuring the sealing performance between the first housing portion 110 and the second housing portion 120. The cross-sectional dimension of the second seal 400 is smaller than that of the stop groove 130 to facilitate the placement of the second seal 400 into the stop groove 130. The second seal 400 is deformed by the compression of the stop rib 140, so that the inner wall of the stop groove 130 and the second seal 400, as well as the stop rib 140 and the second seal 400, are interference fit, ensuring sealing performance. The interference fit dimension is approximately one-third of the dimension of the second seal 400.

[0082] For example, refer to Figure 4 As shown, the cross-section of the second sealing element 400 can be circular, and the cross-sectional diameter can be 1mm to 5mm, such as 1mm, 2mm, 3mm, 4mm, 5mm, etc. Of course, the cross-section of the second sealing element 400 can also be square, elliptical, etc., and this application embodiment does not impose too many restrictions on this.

[0083] Reference Figures 2 to 4 As shown, in a specific embodiment, the first housing part 110 can be the upper cover of the floor brush, the second housing part 120 can be the lower cover of the floor brush, the stop rib 140 is provided on the first housing part 110 (i.e. the upper cover of the floor brush), and the stop groove 130 is provided on the second housing part 120 (i.e. the lower cover of the floor brush).

[0084] In another specific embodiment, the first housing part 110 can be the upper cover of the floor brush, the second housing part 120 can be the lower cover of the floor brush, the stop rib 140 is provided on the second housing part 120 (i.e. the lower cover of the floor brush), and the stop groove 130 is provided on the first housing part 110 (i.e. the upper cover of the floor brush).

[0085] In one embodiment, the first seal 300 and the drive 200 are injection-molded integral parts.

[0086] In this way, the first seal 300 and the drive component 200 are integrally formed to simplify subsequent installation procedures and facilitate the overall installation of the brush structure.

[0087] The first seal 300 can be integrally formed with the gearbox housing of the drive component 200 using an injection molding process.

[0088] Reference Figures 5 to 12 As shown, in some embodiments, the first limiting portion 101 is a first limiting rib facing the drive member 200, and the second limiting portion 210 is a second limiting rib facing the housing 100. Both the first limiting portion 101 and the second limiting portion 210 abut against the first sealing member 300.

[0089] In this way, a limiting space 211 is formed between the first limiting rib and the second limiting rib to limit the first sealing member 300 between the housing 100 and the driving member 200.

[0090] Preferably, both the first limiting rib and the second limiting rib are interference-fitted with the first sealing element 300.

[0091] Reference Figures 5 to 12 As shown, in some embodiments, the first seal 300 includes a first sealing portion 310 and a second sealing portion 320 connected to each other, with an angle between the extending direction of the first sealing portion 310 and the extending direction of the second sealing portion 320. The end of either the first limiting portion 101 or the second limiting portion 210 abuts against the first sealing portion 310.

[0092] In this way, the first sealing part 310 and the second sealing part 320 intersect to form an L-shaped structure. The included angle of the L-shaped structure abuts against the end of the first limiting part 101 or the end of the second limiting part 210. This restricts the movement of the first sealing member 300 from the extending direction of the first sealing part 310 and also restricts the movement of the first sealing member 300 from the extending direction of the second sealing part 320, thereby ensuring the stability of the installation of the first sealing member 300.

[0093] Reference Figure 8 As shown, the first sealing part 310 extends in the -X-+X direction, and the second sealing part 320 extends in the -Y-+Y direction. Preferably, the first sealing part 310 and the second sealing part 320 intersect perpendicularly, with the -X-+X direction being horizontal and the -Y-+Y direction being vertical.

[0094] Reference Figures 8 to 12As shown, the first limiting part 101 and the second limiting part 210 are offset and opposite to each other. The first limiting part 101, part of the housing 100, the second limiting part 210 and part of the driving member 200 together form a limiting space 211. The cross-sectional shape of the limiting space 211 is Z-shaped. The first sealing member 300 is snapped into the limiting space 211 to prevent the first sealing member 300 from loosening or shifting, thereby improving the stability of the installation.

[0095] Reference Figures 8 to 11 As shown, in some embodiments, the end of the second limiting part 210 abuts against the first sealing part 310, that is, the end of the second limiting part 210 is engaged at the angle between the first sealing part 310 and the second sealing part 320, and the second sealing part 320 is located between the first limiting part 101 and the second limiting part 210.

[0096] In one specific embodiment, reference is made to... Figure 8 As shown, the first limiting part 101 is a first limiting rib formed by a portion of the housing 100 protruding toward the drive member 200, and the roller brush (not shown in the figure), the first limiting part 101 and the second limiting part 210 are arranged alternately in sequence.

[0097] In one specific embodiment, reference is made to... Figure 9 As shown, the first limiting part 101 is a first limiting rib formed by a portion of the housing 100 protruding toward the drive member 200, and the roller brush (not shown in the figure), the second limiting part 210 and the first limiting part 101 are arranged in sequence at intervals.

[0098] In one specific embodiment, reference is made to... Figure 10 As shown, the housing 100 has a recessed notch opposite to the second limiting part 210, the sidewall of the recessed notch forms a first limiting rib, and the roller brush (not shown in the figure), the second limiting part 210 and the first limiting part 101 are arranged in sequence at intervals.

[0099] In one specific embodiment, reference is made to... Figure 11 As shown, the housing 100 has a recessed notch opposite to the second limiting part 210, the sidewall of the recessed notch forms a first limiting rib, and the roller brush (not shown in the figure), the first limiting part 101 and the second limiting part 210 are arranged in sequence at intervals.

[0100] Reference Figure 12 As shown, in some other embodiments, the end of the first limiting part 101 abuts against the first sealing part 310, that is, the end of the first limiting part 101 is engaged at the angle between the first sealing part 310 and the second sealing part 320, and the second sealing part 320 is located between the first limiting part 101 and the second limiting part 210.

[0101] It should be noted that the formation structure of the first limiting part 101 and the positional relationship between the second limiting part 210 and the first limiting part 101 can be compared with... Figures 8 to 11 The structure in the embodiments is similar, and will not be described again here.

[0102] Reference Figure 6 and Figure 7 As shown, in some embodiments, the first sealing member 300 further includes an extension 330. The first sealing member 310, the second sealing member 320 and the extension 330 are connected in sequence. The end of the second limiting member 210 abuts against the first sealing member 310. The extension 330 is provided with a first positioning groove 331. The end of the first limiting member 101 is inserted into the first positioning groove 331.

[0103] In this way, during installation, the first sealing element 300 can be connected to the end of the first limiting part 101 through the first positioning groove 331 on the extension 330 to play a positioning role, ensuring that the first sealing part 310 and the second sealing part 320 of the first sealing element 300 are installed in the limiting space 211 formed by the first limiting part 101 and the second limiting part 210, so as to avoid misalignment during installation and affect the sealing effect.

[0104] The first limiting part 101 is a first limiting rib formed by a portion of the housing 100 protruding toward the driving member 200.

[0105] Reference Figure 6 and Figure 7 As shown, in some embodiments, the extension 330 is provided with a first positioning part 332, which is disposed opposite to the first positioning groove 331 on both sides of the extension 330, and the drive member 200 is provided with a second positioning part 220, which is correspondingly connected to the first positioning part 332 and the second positioning part 220.

[0106] In this way, the first positioning part 332 and the second positioning part 220 can play the role of positioning and installation, so that the first sealing member 300 is correspondingly installed on the driving member 200, and the first sealing part 310 and the second sealing part 320 of the first sealing member 300 are correspondingly installed in the limiting space 211 formed by the first limiting part 101 and the second limiting part 210.

[0107] Specifically, the first sealing element 300 can be a sealing ring. During the overall assembly of the floor brush structure, the first sealing element 300 can be connected to the second positioning part 220 on the drive member 200 via the first positioning part 332 on the extension 330, so that the first sealing element 300 is fitted onto the outside of the drive member 200. Then, the drive member 200 is placed on the second housing part 120, and the first sealing element 300 is connected to the first limiting part 101 on the second housing part 120 via the first positioning groove 331 on the extension 330, so that the first sealing part 310 and the second sealing part 320 of the first sealing element 300 are engaged in the limiting space 211 formed by the first limiting part 101 and the second limiting part 210. Finally, the first housing part 110 is placed on the second housing part 120, and the first limiting part 101 on the first housing part 110 is engaged with the first positioning groove 331 on the extension 330 of the first sealing element 300.

[0108] In some embodiments, one of the first positioning part 332 and the second positioning part 220 is a positioning protrusion, and the other is a matching second positioning groove.

[0109] In this way, the positioning protrusion is inserted into the second positioning groove to achieve the positioning function.

[0110] Reference Figure 6 and Figure 7 As shown, in a specific embodiment, the first positioning part 332 is a positioning protrusion, and the second positioning part 220 is a second positioning groove that matches the positioning protrusion.

[0111] In another specific embodiment, the first positioning part 332 is the second positioning groove, and the second positioning part 220 is the positioning protrusion that matches the second positioning groove.

[0112] Secondly, the cleaning equipment provided in this application includes a device body and any of the above-mentioned floor brush structures disposed on the device body.

[0113] Since the cleaning device adopts the floor brush structure in the above embodiments, it also has the advantages and benefits brought by the floor brush structure, which will not be elaborated further here.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
