Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning head and cleaning equipment. Background Technology

[0002] Fabric cleaning machines are widely used in household cleaning, primarily for cleaning soft fabric products such as sofas, curtains, carpets, and upholstered toys. During use, the bristles of the cleaning head may wear down due to prolonged friction and need to be replaced periodically to maintain cleaning effectiveness.

[0003] Traditional cleaning head designs require users to replace the entire cleaning head when changing the bristles, leading to the following problems: users need to disassemble the entire cleaning head, involving the reassembly of components such as water pipes and suction channels, which is cumbersome and can easily damage connecting parts; the cost of replacing the entire cleaning head is high, while the unit price of bristles, as consumable parts, is far lower than the overall cost of the cleaning head, resulting in a waste of resources. Utility Model Content

[0004] The cleaning head and cleaning equipment provided in this application can simplify the replacement of cleaning parts and reduce the cost of use.

[0005] In a first aspect, this application provides a cleaning head, comprising: a housing, the inner side of which defines an installation channel and a suction channel, the housing including a mounting surface opposite to the object to be cleaned, the mounting surface having spaced-apart suction ports and a first through hole; a cleaning component, the cleaning component including a base plate and a cleaning body disposed on the base plate, the base plate being detachably disposed on the mounting surface, the cleaning body being used to clean the object to be cleaned; and a nozzle device, the nozzle device passing through the first through hole and at least partially disposed within the installation channel, the nozzle device being used to spray water or steam onto the object to be cleaned.

[0006] The cleaning head of this application features a detachable cleaning component that connects to the housing. When the cleaning component needs replacement, the user only needs to remove it from the housing and replace it, eliminating the need to detach the entire cleaning head from the connecting pipe. This simplifies the replacement process and reduces the risk of damage to related connecting parts. Furthermore, since only the cleaning component needs to be replaced, the entire cleaning head can be replaced, reducing operating costs and conserving material resources. Users only need to carry multiple sets of spare cleaning components, saving storage space by eliminating the need for multiple spare cleaning heads. In addition, the housing can be equipped with cleaning components for different cleaning scenarios to meet diverse needs.

[0007] In some embodiments, a mounting groove is provided on the mounting surface at a distance from the suction port, the first through hole is formed in the bottom wall of the mounting groove, and the substrate is embedded in the mounting groove.

[0008] By embedding the substrate in the mounting groove, the groove wall can provide all-round support to the substrate in the circumferential direction when the cleaning head is working, which avoids the cleaning component from becoming loose, misaligned or damaged due to the friction of the object to be cleaned, and helps to improve the installation stability of the cleaning component on the housing.

[0009] In some embodiments, the housing is provided with a snap-fit ​​structure, and the substrate is provided with a mating structure, wherein the snap-fit ​​structure and the mating structure snap-fit ​​together.

[0010] This makes the assembly of the housing and cleaning components relatively simple and easy to disassemble.

[0011] In some embodiments, the substrate includes a first side and a second side opposite to each other along a first direction, the snap-fit ​​structure includes a snap fastener on the first side and a snap protrusion on the second side; the outer wall of the housing is provided with a snap hook that engages with the snap fastener, the inner wall of the mounting groove is provided with a snap groove that engages with the snap protrusion, the snap hook engages with the snap fastener, and the snap protrusion is embedded in the snap groove.

[0012] Thus, the assembly method of the housing and cleaning components is relatively simple, making the disassembly and assembly of the housing and cleaning components simple and convenient, and facilitating the replacement of the cleaning components.

[0013] In some embodiments, the periphery of the mounting groove is provided with a clearance notch for avoiding the buckle, and the buckle extends out from the clearance notch and engages with the hook.

[0014] This avoids the clips occupying the internal space of the mounting slot and makes it easier for users to replace the device from the outside of the housing. In addition, it helps to ensure the flatness of the mounting surface, so that the cleaning head can make better contact with the object to be cleaned, thereby improving the cleaning effect of the cleaning equipment.

[0015] In some embodiments, the first through hole is opposite to the substrate, the substrate has a second through hole that is opposite to and communicates with the first through hole, the nozzle device is also disposed through the second through hole, and the cleaning body is spaced apart from the second through hole.

[0016] This prevents substrate interference and obstruction of the nozzle device from spraying cleaning water or steam onto the object to be cleaned, ensuring the reliable operation of the nozzle device.

[0017] In some embodiments, there are multiple cleaning bodies, and the multiple cleaning bodies are respectively located on opposite sides of the second through hole.

[0018] In this way, the layout of the cleaning body and the second through hole is optimized, which can prevent the cleaning body and the nozzle device from interfering with each other.

[0019] In some embodiments, the nozzle device includes: a water distributor passing through the first through hole, the water distributor defining a water distribution chamber, the water distributor including a first chamber wall and a second chamber wall located on opposite sides of the water distribution chamber along a second direction, the first chamber wall having a plurality of spray holes, and the second chamber wall having a connecting nozzle for connecting to a water supply pipeline.

[0020] In this way, the nozzle device can be connected to the main body of the equipment through the water supply pipeline and form a water outlet channel; by setting multiple spray holes, the nozzle device can cover a large area and improve the distribution and diffusion efficiency of clean water or steam; and the overall structure of the water distributor is relatively simple and easy to manufacture.

[0021] In some embodiments, the housing includes: a main housing including a front cover and a rear cover, the front cover and the rear cover being arranged opposite to each other along a second direction and jointly defining the mounting channel, the first through hole being formed in the front cover, and the side surface of the front cover with the first through hole forming part of the mounting surface; a channel cover plate disposed on one side of the main housing, the channel cover plate and the main housing jointly defining the suction channel, the suction port being formed in the channel cover plate, and the side surface of the channel cover plate with the suction port forming another part of the mounting surface.

[0022] Thus, the housing in this embodiment is composed of parts such as a front cover, a rear cover, and a channel cover, which has a simple structure and is easy to assemble and disassemble.

[0023] Secondly, this application provides a cleaning device, comprising: a device body; and the aforementioned cleaning head, wherein the cleaning head is connected to the device body via a connecting pipe.

[0024] The cleaning equipment of this application, by setting the aforementioned cleaning head, allows users to easily replace the cleaning parts when their cleaning effect decreases due to prolonged use. The replacement operation is simple, efficient, and can reduce operating costs. Attached Figure Description

[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] Fabric cleaning machines are widely used in household cleaning, primarily for cleaning soft fabric products such as sofas, curtains, carpets, and upholstered toys. During use, the brush bristles may wear down due to prolonged friction and require regular replacement to maintain cleaning effectiveness.

[0047] Traditional brush head designs require users to replace the entire brush head assembly when changing bristles, leading to the following problems: Operational complexity: Users need to disassemble the entire brush head, involving the reassembly of components such as water pipes and suction channels, which is cumbersome and prone to damaging connecting parts; Storage burden: Multiple spare brush heads occupy significant storage space, especially in small apartments where proper storage is difficult; High usage cost: Replacing the entire brush head is costly, while the unit price of bristles, as consumable parts, is far lower than the overall cost of the brush head, resulting in resource waste; Poor functional adaptability: Different cleaning scenarios (such as deep carpet cleaning and delicate fabric care) require different bristle types, but existing brush head structures cannot flexibly replace bristles to adapt to diverse needs.

[0048] In view of this, the present application provides a cleaning head and a cleaning device. By detachably connecting the cleaning component to the housing, when the cleaning component needs to be replaced, the user only needs to remove the cleaning component from the housing and replace it, without having to remove the entire cleaning head from the connecting pipe. This eliminates the need for reassembly of the cleaning head and connecting pipe, simplifies the replacement operation, and reduces the risk of damaging related connecting components. Moreover, since only the cleaning component needs to be replaced, and the entire cleaning head does not need to be replaced, it helps to reduce usage costs and save material resources.

[0049] refer to Figures 1-5 The cleaning device 100 in this embodiment can be a fabric cleaning machine, a vacuum cleaner, a mite remover, or other types of cleaning device 100.

[0050] refer to Figure 1 The cleaning equipment 100 may include a main body 2 and a cleaning head 1. The main body 2 may include a casing, a clean water tank housed within the casing, a waste collection device, a suction device, an electrical control device, and other components. The bottom of the casing may be equipped with casters or other walking devices for easy movement. The cleaning head 1 and the main body 2 can be connected via connecting pipes. The cleaning equipment 100 can both transport clean water from the clean water tank to the cleaning head 1 through the connecting pipes for cleaning the objects to be cleaned, and can also suction wastewater and dirt removed from the objects by the cleaning head 1 back into the waste collection device for collection and temporary storage. The waste collection device may include components such as a dust cup or a wastewater tank. The electrical control device can serve as the control system for the cleaning equipment 100, used to control the opening, closing, operating mode, and other working states of the cleaning equipment 100.

[0051] The items to be cleaned can be flexible fabric products such as sofas, curtains, carpets, and upholstered toys.

[0052] Further, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The cleaning head 1 in this embodiment may include: a housing 11, a cleaning component 12, and a nozzle device 13.

[0053] The housing 11 has an inner section defining an installation channel 112 and a suction channel 115. The installation channel 112 can be used to install water supply pipes, wiring harnesses, and other components, while the suction channel 115 is used for suction. The housing 11 includes a mounting surface 110 opposite to the object to be cleaned. The mounting surface 110 is the end face of the cleaning head 1 opposite to the object to be cleaned when the cleaning equipment 100 is working. The mounting surface 110 can be planar or non-planar.

[0054] The mounting surface 110 is provided with a suction port 116 and a first through hole 113. The suction port 116 and the first through hole 113 are arranged at intervals. The suction port 116 is connected to the suction channel 115, and the first through hole 113 is connected to the mounting channel 112. The nozzle device 13 passes through the first through hole 113.

[0055] The cleaning component 12 may include a substrate 121 and a cleaning body 122. The substrate 121 is detachably disposed on the mounting surface 110. The substrate 121 may be adapted to the shape of the area on the mounting surface 110 for mounting the substrate 121. The substrate 121 and the housing 11 may be connected by screws, snap-fit, or other mechanical connection methods to facilitate separation or disassembly of the substrate 121 and the housing 11. The substrate 121 may be offset from the first through hole 113 to eliminate the need for a through hole structure to avoid the nozzle device 13 (as described in the second through hole 1211 below); alternatively, the substrate 121 may be opposite to the first through hole 113, in which case a through hole structure to avoid the nozzle device 13 may be formed on the substrate 121.

[0056] The cleaning body 122 is used to clean the object to be cleaned. The cleaning body 122 may include rubber strips, bristles, a tapping device, etc.

[0057] At least a portion of the structure of the nozzle device 13 is disposed within the installation channel 112. The nozzle device 13 is used to spray water or steam onto the object to be cleaned. By spraying water or high-temperature steam onto the object to be cleaned, the stains on the object to be cleaned can be softened, making it easier for the cleaning component 12 to remove them.

[0058] When the cleaning equipment 100 is working, the main body 2 of the equipment can supply steam or water to the nozzle device 13 through the water supply pipe in the installation channel 112 to soften the stains on the object to be cleaned; after the stains are removed from the object to be cleaned, they flow to the collection device in the main body 2 of the equipment through the suction port 116 and the suction channel 115 under the action of the suction device in the main body 2.

[0059] The cleaning head 1 of this application embodiment has a detachable connection between the cleaning component 12 and the housing 11. When the cleaning component 12 needs to be replaced, the user only needs to remove the cleaning component 12 from the housing 11 and replace it. There is no need to remove the entire cleaning head 1 from the connecting pipe. This saves the trouble of reassembling the cleaning head 1 and the connecting pipe and other components, simplifies the replacement operation steps, and is less likely to damage the related connecting components. Moreover, since only the cleaning component 12 needs to be replaced, and the entire cleaning head 1 does not need to be replaced, it is beneficial to reduce the cost of use and save material resources.

[0060] Furthermore, users only need multiple sets of spare cleaning parts 12 for replacement, eliminating the need for multiple sets of spare cleaning heads 1 and saving storage space; in addition, the housing 11 can be equipped with cleaning parts 12 for different cleaning scenarios (such as deep cleaning of carpets and care of delicate fabrics) to meet diverse needs.

[0061] Optionally, the substrate 121 can be made of plastic, which reduces the cost of the cleaning component 12, makes it easier to manufacture, and lowers the user's operating costs; or, the substrate 121 can be made of metal, which provides higher strength and better quality. Of course, this application is not limited to these options, and the material of the substrate 121 can be reasonably selected according to actual needs.

[0062] In some embodiments, combined with Figure 3 and Figure 4 A mounting groove 1101 is provided on the mounting surface 110. The mounting groove 1101 is spaced apart from the suction port 116. A first through hole 113 is provided on the bottom wall of the mounting groove 1101. The substrate 121 is adapted to be embedded in the mounting groove 1101. By embedding the substrate 121 in the mounting groove 1101, when the cleaning head 1 is working, the groove wall of the mounting groove 1101 can provide all-round support for the substrate 121 in the circumferential direction, so as to prevent the cleaning component 12 from being loosened, misaligned or damaged by the friction of the object to be cleaned, which is conducive to improving the installation stability of the cleaning component 12 on the housing 11.

[0063] Optionally, the depth of the mounting groove 1101 may be greater than the thickness of the substrate 121; or, the depth of the mounting groove 1101 may be less than the thickness of the substrate 121; or, the depth of the mounting groove 1101 may be equal to the thickness of the substrate 121.

[0064] In some embodiments, the housing 11 is provided with a snap-fit ​​structure, and the base plate 121 is provided with a mating structure, wherein the snap-fit ​​structure and the mating structure snap-fit ​​together. This makes the assembly of the housing 11 and the cleaning component 12 simpler and easier to disassemble and assemble.

[0065] In some embodiments, combined with Figure 4 and Figure 5The substrate 121 may include a first side surface 1214 and a second side surface 1215, the first side surface 1214 and the second side surface 1215 being along a first direction (e.g., Figure 4 The Z-direction shown is arranged opposite to each other, and the snap-fit ​​structure includes a snap fastener 1212 on the first side 1214 and a snap protrusion 1213 on the second side 1215.

[0066] The outer wall of the housing 11 is provided with a hook 117 that cooperates with the buckle 1212, and the inner wall of the mounting groove 1101 is provided with a groove that cooperates with the protrusion 1213. The hook 117 is engaged with the buckle 1212, and the protrusion 1213 is embedded in the groove.

[0067] When installing the cleaning component 12 onto the housing 11, the protrusion 1213 can be first inserted at an angle into the corresponding slot to achieve initial positioning of the cleaning component 12 and the housing 11. Then, the cleaning component 12 is pressed so that the base plate 121 is fully positioned in the mounting groove 1101. At the same time, the buckle 1212 can be engaged with the hook 117 under the pressing action, thus achieving the assembly of the cleaning component 12 and the housing 11. When removing the cleaning component 12 from the housing 11, the buckle 1212 can be reversed to disengage it from the hook 117. Then, the cleaning component 12 is pulled out, and the protrusion 1213 and the slot separate simultaneously, thus completing the disassembly.

[0068] This makes the disassembly and assembly of the housing 11 and the cleaning component 12 simple and convenient, and facilitates the replacement of the cleaning component 12.

[0069] In some embodiments, since the substrate 121 is located in the mounting groove 1101 and the buckle 1212 is located on the outer periphery of the substrate 121, in order to avoid the buckle 1212 occupying the internal space of the mounting groove 1101 and to facilitate the user to perform replacement operations from the outside of the housing 11, the buckle 1212 needs to be placed outside the mounting groove 1101.

[0070] Therefore, in this embodiment, a clearance notch 1102 is provided around the periphery of the mounting groove 1101 to avoid the buckle 1212. The buckle 1212 extends through the clearance notch 1102 and engages with the hook 117. In this state, the buckle 1212 will be located inside the clearance notch 1102, avoiding protrusion from the mounting surface 110. This helps to ensure the flatness of the mounting surface 110, allowing the cleaning head 1 to make better contact with the object to be cleaned, thereby improving the cleaning effect of the cleaning device 100 on the object to be cleaned.

[0071] In some embodiments, combined with Figures 3-5The first through hole 113 is opposite to the substrate 121. The substrate 121 has a second through hole 1211 that is opposite to and communicates with the first through hole 113. The nozzle device 13 is also disposed through the second through hole 1211. The cleaning body 122 is spaced apart from the second through hole 1211. In this way, the substrate 121 can prevent the nozzle device 13 from interfering with and blocking the nozzle device 13 from spraying cleaning water or steam onto the object to be cleaned, thus ensuring the reliable operation of the nozzle device 13.

[0072] In some embodiments, the shape of the nozzle device 13 is adapted to the shapes of the first through hole 113 and the second through hole 1211 to ensure the installation stability of the nozzle device 13. (See reference) Figure 4 The first through hole 113, the second through hole 1211 and the nozzle device 13 are all formed in an elongated oval shape; in addition, the first through hole 113, the second through hole 1211 and the nozzle device 13 can also be circular, square or other shapes, and this embodiment does not limit them.

[0073] Optionally, the nozzle device 13 and the first through hole 113 can be an interference fit to provide reliable mounting support for the nozzle device 13 using the housing 11; meanwhile, the nozzle device 13 and the second through hole 1211 can be a clearance fit to reduce the difficulty of assembling and separating the nozzle device 13 and the cleaning component 12.

[0074] In some embodiments, there are multiple cleaning bodies 122, and the multiple cleaning bodies 122 are respectively located on opposite sides of the second through hole 1211. For example Figure 5 As shown, the cleaning body 122 includes multiple clumps of bristles arranged in an array, for example, in multiple rows, with the rows arranged along a first direction, and each row including bristles along a third direction (e.g., ...). Figure 4 The cleaning body 122 has several clumps of bristles arranged in the Y direction. Some of the bristles are located on one side of the second through hole 1211 along the first direction, and the other part is located on the other side of the second through hole 1211 along the first direction. In this way, the layout of the cleaning body 122 and the second through hole 1211 is optimized, and interference between the cleaning body 122 and the nozzle device 13 can be avoided.

[0075] In some embodiments, reference Figure 4 The nozzle device 13 may include a water distributor 131, which passes through the first through hole 113 and defines a water distribution chamber. The water distributor 131 includes components located along the second direction (corresponding to...) Figure 4The device comprises a first chamber wall and a second chamber wall on opposite sides (in the X direction). The first chamber wall faces the object to be cleaned and has multiple spray holes 132. The second chamber wall has a connecting nozzle 133 for connecting to a water supply pipe. Thus, the nozzle device 13 can be connected to the main body 2 via the water supply pipe, forming a water outlet channel. By providing multiple spray holes 132, the nozzle device 13 can cover a larger area, improving the distribution and diffusion efficiency of clean water or steam. Furthermore, the overall structure of the water distributor 131 is relatively simple and easy to manufacture.

[0076] In some embodiments, reference Figure 1 and Figure 4 The housing 11 may include: a main housing 111 and a channel cover 114.

[0077] The main housing 111 includes a front cover 1111 and a rear cover 1112. The front cover 1111 and the rear cover 1112 are arranged opposite to each other along the second direction and together define the mounting channel 112. A first through hole 113 is formed in the front cover 1111. The side surface of the front cover 1111 with the first through hole 113 forms part of the mounting surface 110.

[0078] For example, the front cover 1111 may include a front panel and a front side panel, the front side panel being formed as an arc-shaped panel, the front side panel surrounding a portion of the front panel along the circumferential direction, the rear cover 1112 may include a rear top cover and a rear side panel, the rear side panel surrounding a portion of the rear cover 1112 along the circumferential direction, the rear top cover overlapping and fixed to the top of the front panel, the front side panel and the rear side panel being interconnected and jointly forming the mounting channel 112, the first through hole 113 being formed in the front panel, and a portion of the structure of the mounting surface 110 being formed by the side surface of the front panel facing away from the mounting channel 112.

[0079] The channel cover 114 is located on one side of the main housing 111. The channel cover 114 and the main housing 111 together define the suction channel 115. The suction port 116 is opened on the channel cover 114. The side surface of the channel cover 114 where the suction port 116 is opened constitutes another part of the mounting surface 110.

[0080] For example, the channel cover 114 is located on the side of the rear top cover opposite to the mounting channel 112 along the first direction. The channel cover 114 and the rear top cover together define the suction channel 115. The suction port 116 is located on the side wall of the channel cover 114 facing the front end plate. The channel cover 114 and the rear side wall can be connected by snap-fit, bolt connection or other means.

[0081] Thus, the housing 11 in this embodiment is composed of parts such as the front cover 1111, the rear cover 1112, and the channel cover 114, which has a simple structure and is easy to disassemble and assemble.
