However, after wet cleaning, the wastewater collection pipes of these machines may contain residual liquid and dirt, which could potentially breed bacteria and produce odors. This could lead to secondary pollution during subsequent cleaning processes, reducing the user experience. Utility Model Content

[0003] The present invention introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0008] For example, the outer wall of the suction channel is provided with a mounting base. The push switch includes a push sensor, a push part and an elastic reset member. The push sensor is located inside the mounting base and is electrically connected to the liquid pump. The push part is movably connected to the mounting base and can move closer to or further away from the push sensor. The elastic reset member is connected to the mounting base and the push part to drive the push part to reset to the initial position. When the push part moves towards the push sensor to a designated position, it contacts or presses the push sensor, causing the push sensor to switch its electrical state.

[0009] For example, the second spraying assembly includes a first nozzle and a first inlet port, the first nozzle being exposed inside the suction channel, and the first inlet port being located outside the suction channel and connected to the inlet pipe via a shifting mechanism.

[0010] For example, the liquid discharge direction of the second spray component is toward the air inlet of the suction channel, and / or, the liquid discharge direction of the second spray component is toward the air outlet of the suction channel, and / or, the liquid discharge direction of the second spray component is perpendicular to the side wall of the suction channel.

A first spraying component, a second spraying component, a shifting mechanism, and a push switch are installed in the installation notch. A first clearance hole is provided on the cover plate to avoid the second nozzle of the first spraying component. A second clearance hole is provided on the cover plate to avoid the shifting mechanism. A third clearance hole is provided on the cover plate to avoid the push switch.

[0013] An embodiment of the second aspect of this application provides a cleaning device, including: a machine body and a cleaning brush head as described above.

[0014] For example, the cleaning brush head is detachably connected to the machine body.

[0015] For example, the cleaning equipment also includes: a liquid storage section, a recycling bin, and an air suction fan disposed on the main body of the machine. The liquid storage section is connected to the liquid inlet pipe of the cleaning brush head. The recycling bin is provided with a sludge inlet and an exhaust outlet. The sludge inlet is connected to the sludge suction channel of the cleaning brush head through a sludge suction pipe. The exhaust outlet is connected to the air inlet of the air suction fan. The air outlet of the air suction fan is connected to the external environment.

[0016] The cleaning brush head and cleaning device provided in this application embodiment, by connecting the cleaning device to the main body of the machine, can realize the cleaning operation of the surface to be cleaned, and also realize the self-cleaning operation of the cleaning brush head and some pipelines of the cleaning device, which greatly improves the functionality of the cleaning device and realizes the diversification of cleaning functions.

Detailed Implementation

[0031] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they specify the presence of features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0033] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0034] like Figure 1 As shown, an embodiment of this utility model provides a cleaning brush head 100. An embodiment of this application also provides a cleaning device 200, with the cleaning brush head 100 used in the cleaning device 200. Specifically, the cleaning device 200 can be a fabric cleaning machine, a floor scrubber, or other cleaning device 200 with wet cleaning functions. It is understood that the cleaning device 200 can also be other cleaning devices 200 with wet cleaning functions.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in the embodiment of this application, a cleaning brush head 100 is provided, including: a suction channel 110; a first spraying assembly 120 disposed outside the suction channel 110 and configured to spray liquid onto the surface to be cleaned; a second spraying assembly 130 passing through the side wall of the suction channel 110 and configured to spray liquid into the suction channel 110; a shifting mechanism 140 and an inlet pipe 150. The shifting mechanism 140 is disposed outside the suction channel 110 and includes a first gear and a second gear. In the first gear, the first spraying assembly 120 is connected to the inlet pipe 150, and in the second gear, the second spraying assembly 130 is connected to the inlet pipe 150.

[0036] The cleaning brush head 100 provided in this embodiment includes a suction channel 110, a first spray assembly 120, a second spray assembly 130, a shifting mechanism 140, and an inlet pipe 150. The shifting mechanism 140 includes a first gear and a second gear. In the first gear, the first spray assembly 120 is connected to the inlet pipe 150, and liquid is supplied to the first spray assembly 120 through the inlet pipe 150 so that it can be sprayed onto the surface to be cleaned. In this way, other components of the cleaning device 200 can work to treat the dirt and sludge on the surface to be cleaned, thereby achieving the cleaning operation of the surface to be cleaned. In the second setting, the second spray assembly 130 is connected to the inlet pipe 150, and liquid is supplied from the inlet pipe 150 to the second spray assembly 130. This liquid is then sprayed into the suction channel 110, allowing other components of the cleaning device 200 to operate and clean the inside of the suction channel 110 and some of the internal pipes of the cleaning device 200. This achieves self-cleaning of the cleaning brush head 100 and parts of the cleaning device 200, improving the hygiene and health of the cleaning device 200. It reduces or avoids the possibility of residual dirt and grime in the suction channel 110, which could lead to bacterial growth and odors. This improves the cleanliness of the cleaning brush head 100 and the inside of the cleaning device 200, reducing the possibility of secondary contamination and minimizing threats to the health of family members. It also simplifies the manual cleaning of the suction channel 110 and some of the pipes of the cleaning device 200, saving users time and effort. Especially for hard-to-reach areas, the automatic cleaning function can more effectively complete the cleaning work, facilitating the maintenance of the cleaning device 200. Meanwhile, regularly performing self-cleaning operations on the cleaning brush head 100 and the cleaning device 200 can prevent dirt buildup, reduce the risk of malfunctions, and thus extend the service life of the cleaning brush head 100 and the cleaning device 200. Cleaner equipment typically operates more efficiently, allowing the cleaning device 200 to work in optimal condition and improving energy efficiency. Furthermore, the self-cleaning function enhances the product's intelligence and convenience, improving the overall user experience.

[0037] Therefore, the improved cleaning brush head 100 in this embodiment enables the cleaning device 200 to perform cleaning operations on the surface to be cleaned, and also enables self-cleaning operations of the cleaning brush head 100 and some pipelines of the cleaning device 200, greatly improving the functionality of the cleaning device 200 and realizing the diversification of its functions. Simultaneously, the function switching between cleaning mode and self-cleaning mode can be performed through the shifting mechanism 140 on the cleaning brush head 100. The principle is simple and easy to implement, requiring no new parts to be cleaned, nor damaging the integrity of the machine body 210's appearance. This allows the cleaning brush head 100 to achieve diversified functions simply by working with the existing machine body 210. It is low-cost, lightweight, and helps improve the thoroughness of self-cleaning. Furthermore, it is easy to operate, with a low user learning cost, conforming to user operating habits. The entire process is simple and easy to operate, with clear logic, facilitating blind operation by customers, and suitable for widespread application.

[0038] Among them, such as Figure 3 and Figure 6 As shown, the shift mechanism 140 is located outside the suction channel 110, which allows users to operate the shift mechanism 140 from outside the suction channel 110 to switch between cleaning mode and self-cleaning mode. It is simple to operate, convenient to use, and conforms to user operating habits.

[0039] Since the liquid inlet pipe 150 needs to be connected to the shifting mechanism 140, the entire liquid inlet pipe 150 can be placed outside the suction channel 110. In this way, the liquid inlet pipe 150 will not affect the sealing performance of the suction channel 110. Alternatively, part of the liquid inlet pipe 150 can be placed outside the suction channel 110 and connected to the shifting mechanism 140, while part of the liquid inlet pipe 150 can be placed inside the suction channel 110. This minimizes the impact of the liquid inlet pipe 150 being exposed outside the suction channel 110 on the cleanliness of the cleaning brush head 100, thereby improving the aesthetics of the cleaning brush head 100.

[0040] Among them, such as Figure 2 , Figure 3 and Figure 7As shown, the first spraying assembly 120 is disposed outside the suction channel 110, facilitating the spraying of liquid onto the surface to be cleaned and preventing the first spraying assembly 120 from penetrating the suction channel 110 and affecting its sealing performance. Specifically, the first spraying assembly 120 can be connected to the outer wall of the suction channel 110, or it can be connected to other components and located outside the suction channel 110. When the first spraying assembly 120 is connected to the outer wall of the suction channel 110, the connection between the first spraying assembly 120 and the outer wall of the suction channel 110 can be detachable, facilitating disassembly and separation for maintenance and replacement. It is understood that in some examples, the first spraying assembly 120 and the outer wall of the suction channel 110 can also be fixedly connected by adhesive, welding, or other methods. Understandably, in some examples, if the sealing of the suction channel 110 can be guaranteed, the first spraying assembly 120 can also be installed through the suction channel 110.

[0041] Among them, such as Figure 6 As shown, the second spraying assembly 130 is installed through the side wall of the suction channel 110 to ensure that the second spraying assembly 130 can smoothly spray liquid into the suction channel 110 and smoothly connect with the shifting mechanism 140 outside the suction channel 110.

[0042] The first spraying assembly 120 and the second spraying assembly 130 may have the same structure or different structures.

[0043] Furthermore, the cleaning equipment 200 includes a machine body 210, a cleaning brush head 100 connected to the machine body 210, and an air suction fan installed on the machine body 210. The air suction fan provides negative pressure airflow, and the suction channel 110 is connected to the air suction fan of the cleaning equipment 200 via a suction pipe. Thus, when the shifting mechanism 140 is in the first position and the first spray component 120 is connected to the liquid inlet pipe 150, the first spray component 120 sprays liquid onto the surface to be cleaned, and the air suction fan operates. Under the action of negative pressure airflow, the dirt and liquid on the surface to be cleaned can be collected into the interior of the cleaning equipment 200 through the suction channel 110 and the suction pipe, thereby realizing the cleaning operation on the surface to be cleaned. When the shift mechanism 140 is in the second gear and the second spray component 130 is connected to the liquid inlet pipe 150, the second spray component 130 sprays liquid into the inside of the suction channel 110. The suction fan works, and under the action of negative pressure airflow, the liquid can be collected from the suction channel 110 and the suction pipe into the inside of the cleaning equipment 200. During this process, the liquid will flush the side walls of the suction channel 110 and the suction pipe to achieve self-cleaning operation of the suction channel 110 and the suction pipe.

[0044] Furthermore, such as Figure 1 As shown, the cleaning equipment 200 also includes a recycling bin 230 mounted on the machine body 210. The recycling bin 230 is connected to the suction channel 110 and also to the air inlet of the suction fan. When the suction fan is working, it can collect dirt and sludge from the surface to be cleaned or from the suction channel 110 into the recycling bin 230. Specifically, when the shift mechanism 140 is in the second gear, during the self-cleaning operation of the cleaning equipment 200, the second spray component 130 sprays liquid into the suction channel 110. Under the action of the suction fan, the liquid flows through the suction channel 110 and the suction pipe into the recycling bin 230. During this process, the liquid cleans the pipe walls along the path it travels, thus achieving a cleaning operation of the suction channel 110 and the suction pipe. In other words, the suction channel 110 and the suction pipe between the recycling bin 230 and the point where the liquid lands in the suction channel 110 undergo self-cleaning, greatly increasing the cleaning range and the thoroughness of the cleaning.

[0045] Furthermore, such as Figure 1 As shown, the cleaning equipment 200 also includes a liquid storage section 220 disposed on the machine body 210. The liquid storage section 220 is used to contain cleaning liquid, which includes at least one of water, detergent, bactericide, and disinfectant. The liquid storage section 220 is connected to the liquid inlet pipe 150, so that the cleaning liquid in the liquid storage section 220 can be delivered to the liquid inlet pipe 150. It is understood that in some examples, the liquid storage section 220 can also be separately configured to supply liquid to the liquid inlet pipe 150, such as the liquid storage section 220 being a separate accessory detached from the machine body 210 and not connected to the machine body 210.

[0046] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some possible embodiments provided in this application, the shifting mechanism 140 includes a switching valve, at least a portion of the operating portion 141 of which is exposed to the outside of the cleaning brush head 100.

[0047] The switching valve controls the flow direction of fluid between different channels, enabling diversion, merging, or alteration of the medium's flow path. Thus, the switching valve connects the inlet pipe 150, the first spray assembly 120, and the second spray assembly 130. Furthermore, the operating part 141 of the switching valve allows switching the connection between the inlet pipe 150 and the first spray assembly 120 and the second spray assembly 130, enabling switching between cleaning and self-cleaning functions. The design is simple, easy to implement, and low-cost.

[0048] By exposing at least a portion of the operating part 141 to the outside of the cleaning brush head 100, users can easily switch between the first and second speed settings by operating the operating part 141 from the outside of the cleaning brush head 100, thus enabling the switching between cleaning mode and self-cleaning mode. The operation is simple, conforms to the daily usage habits of ordinary consumers, requires no training or instruction manual, is convenient to use, and has a high user willingness, making it suitable for widespread application. It is understood that either a portion or the entire operating part 141 may be exposed to the outside of the cleaning brush head 100.

[0049] like Figure 6 and Figure 8 As shown, in some possible embodiments provided in this application, the switching valve further includes a valve body 142 and a valve core. The first port of the valve body 142 is connected to the liquid inlet pipe 150, the second port of the valve body 142 is connected to the first spray assembly 120, such as the second port being connected to the first spray assembly 120 through the first water inlet branch 121, and the third port of the valve body 142 is connected to the second spray assembly 130, such as the third port being connected to the second spray assembly 130 through the second water inlet branch 133. The valve core is disposed inside the valve body 142, and the operating part 141 is connected to the valve core. The operating part 141 switches between a first position and a second position to connect the first port to one of the second port and the third port through the valve core.

[0050] Specifically, the operating unit 141 is linked with the valve core. The movement of the operating unit 141 can drive the valve core to move. When the operating unit 141 moves to the first position, the valve core moves to connect the first port and the second port, thereby connecting the liquid inlet pipe 150 and the first spraying assembly 120. Liquid can be supplied from the liquid inlet pipe 150 to the first spraying assembly 120 so that it can be sprayed onto the surface to be cleaned through the first spraying assembly 120.

[0051] When the operating unit 141 moves to the second position, the valve core moves to connect the first port and the third port, thereby connecting the liquid inlet pipe 150 and the second spray assembly 130. Liquid can be supplied from the liquid inlet pipe 150 to the second spray assembly 130 so that it can be sprayed into the interior of the suction channel 110 through the second spray assembly 130.

[0052] like Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, in some possible embodiments provided in this application, the cleaning brush head 100 further includes: a press switch 160 and a liquid pump. The press switch 160 is disposed outside the suction channel 110, and at least a portion of the press switch 160 is exposed outside the cleaning brush head 100. The liquid pump is disposed on the liquid inlet line 150, and the press switch 160 is configured to switch the on / off state of the liquid pump.

[0053] In this embodiment, a liquid pump is installed on the inlet pipe 150, enabling the delivery or cessation of liquid delivery. A push-button switch 160 is installed outside the suction channel 110 to switch the on / off state of the liquid pump, with at least a portion of the push-button switch 160 exposed to the outside of the cleaning brush head 100. This allows the user to conveniently switch the on / off state of the liquid pump from outside the cleaning brush head 100 via the push-button switch 160, thereby controlling the liquid delivery state. This allows the liquid to be delivered via the inlet pipe 150 to the first spray assembly 120 or the second spray assembly 130, or to stop the liquid delivery, thus stopping the spraying of the first spray assembly 120 or the second spray assembly 130. The operation is simple and convenient.

[0054] The liquid pump is installed on the liquid inlet pipe 150, which is connected to the first spray assembly 120 and the second spray assembly 130 via a shifting mechanism 140. Thus, by cooperating with the liquid pump and the shifting mechanism 140, the liquid discharge states of the first spray assembly 120 and the second spray assembly 130 can be controlled simultaneously. Compared to using two separate liquid pumps to control the liquid discharge states of the first and second spray assemblies 120 and 130 respectively, this simplifies the number of liquid pumps, simplifies the structure, and saves costs. Furthermore, since the on / off state of the liquid pump can be switched by a push-button switch 160, at least a portion of the push-button switch 160 and at least a portion of the shifting mechanism 140 are exposed outside the cleaning brush head 100. This allows the user to conveniently operate the push-button switch 160 and the shifting mechanism 140 from outside the cleaning brush head 100 to control the liquid discharge states of the first and second spray assemblies 120 and 130.

[0055] Specifically, the user uses the operating unit 141 to put the shifting mechanism 140 into the first position, connecting the liquid inlet pipe 150 to the first spraying assembly 120. At this time, the user operates the pressing switch 160 to turn on the liquid pump, delivering liquid to the liquid inlet pipe 150 and spraying it onto the surface to be cleaned via the liquid inlet pipe 150, the shifting mechanism 140, and the first spraying assembly 120. The user then operates the pressing switch 160 again to turn off the liquid pump, stopping the liquid delivery and preventing the first spraying assembly 120 from dispensing liquid.

[0056] The user uses the operating unit 141 to shift the gear mechanism 140 to the second position, connecting the inlet pipe 150 to the second spray assembly 130. At this time, the user operates the press switch 160 to turn on the pump, supplying liquid to the inlet pipe 150, which then passes through the inlet pipe 150, the shift mechanism 140, and the second spray assembly 130 before spraying it into the suction channel 110. The user then operates the press switch 160 again to turn off the pump, stopping the liquid supply and preventing the second spray assembly 130 from dispensing liquid.

[0057] like Figure 7 and Figure 9 As shown, in some possible embodiments provided in this application, the outer wall of the suction channel 110 is provided with a mounting base 111, and the push switch 160 includes a push sensor 161, a push part 162 and an elastic reset member 163. The push sensor 161 is located inside the mounting base 111 and is electrically connected to the liquid pump. The push part 162 is movably connected to the mounting base 111 and can move closer to or further away from the push sensor 161. The elastic reset member 163 is connected to the mounting base 111 and the push part 162 to drive the push part 162 to reset to the initial position. When the push part 162 moves towards the push sensor 161 to a designated position, it contacts or presses the push sensor 161 to switch the electrical state of the push sensor 161.

[0058] The electrical state of the pressure sensor 161 can include an on-state and an off-state. The pressure sensor 161 is connected to the liquid pump via an electrical connection line 164. When the pressure sensor 161 is pressed and switched to the on-state, the pressure sensor 161 is electrically connected to the liquid pump and energized, causing the liquid pump to be in the on state and performing liquid supply operation, that is, the liquid can be delivered to the first spray assembly 120 or the second spray assembly 130 through the liquid inlet pipe 150. When the pressure sensor 161 is pressed and switched to the off-state, the pressure sensor 161 is de-energized from the liquid pump, causing the liquid pump to be in the off state and unable to perform liquid supply operation. The liquid cannot flow through the liquid inlet pipe 150 to be supplied to the first spray assembly 120 or the second spray assembly 130.

[0059] The elastic reset member 163 ensures that the pressing part 162 moves towards the pressure sensor 161 under pressure, and after the pressure is released, the pressing part 162 can move away from the pressure sensor 161 under the action of the elastic reset member 163 to reset to the initial position. This facilitates subsequent operation of the pressing part 162 for reuse, thereby achieving the switching operation of the electrical state of the pressure sensor 161. Specifically, the elastic reset member 163 can be a spring, a sheet, a tension spring, a torsion spring, or other structures, such as... Figure 4 As shown, the elastic reset element 163 is a spring.

[0060] like Figure 5 and Figure 6 As shown, in some possible embodiments provided in this application, the second spraying assembly 130 includes a first nozzle 131 and a first liquid inlet 132. The first nozzle 131 is exposed inside the suction channel 110, and the first liquid inlet 132 is located outside the suction channel 110 and connected to the liquid inlet pipe 150 through a shifting mechanism 140. This allows the second spraying assembly 130 to communicate smoothly with the liquid inlet pipe 150 and ensures that the liquid sprayed from the first nozzle 131 of the second spraying assembly 130 flows smoothly into the suction channel 110.

[0061] Specifically, the first liquid inlet 132 of the second liquid spraying assembly 130 can be connected to the third port of the switching valve of the shifting mechanism 140 through the second water inlet branch 133 pipeline, while the first port of the switching valve is connected to the liquid inlet pipeline 150. When the operation unit 141 switches to the second gear, the valve core of the switching valve connects the first port and the third port, thereby realizing the connection operation between the second liquid spraying assembly 130 and the liquid inlet pipeline 150.

[0062] like Figure 5 As shown, in some possible embodiments provided in this application, the suction channel 110 includes an air inlet 112 and an air outlet 113. In the direction of the negative pressure airflow, the air inlet 112 is located on the side of the air outlet 113 furthest from the machine body 210; that is, the inlet is farther from the machine body 210, and the air outlet 113 is closer to the machine body 210. Under the action of the suction fan, the negative pressure airflow flows from the air inlet 112 along the suction channel 110 and into the machine body 210 through the air outlet 113. Specifically, the flow direction of the negative pressure airflow in the suction channel 110 is as follows: Figure 5 As shown by the dashed arrow in the image.

[0063] The second spray component 130 directs its liquid output towards the air inlet 112 of the suction channel 110, allowing the liquid sprayed from the second spray component 130 to be directed towards the air inlet 112 of the suction channel 110. For example, the liquid can be sprayed towards a location within the suction channel 110 close to the air inlet 112, or directly towards the air inlet 112 itself. This reduces the distance between the liquid landing point and the air inlet 112, increasing the length of the liquid flow path within the suction channel 110. Consequently, during self-cleaning operations, this improves the thoroughness of cleaning the suction channel 110. The suction pipe from the liquid landing point (e.g., near the air inlet 112) to the recovery bin 230 within the machine body 210 can be flushed with liquid to achieve self-cleaning, significantly enhancing the thoroughness of the self-cleaning process.

[0064] In this configuration, the liquid outlet direction of the second spray component 130 is towards the air outlet 113 of the suction channel 110. In this case, the second spray component 130 can be positioned as close as possible to the air inlet 112 of the suction channel 110 to reduce the distance between the liquid landing point and the air inlet 112, thereby maximizing the length of the liquid flow path within the suction channel 110 and improving the thoroughness of cleaning the suction channel 110. This allows the suction pipe from the liquid landing point in the suction channel 110 to the recycling bin 230 inside the machine body 210 to be flushed by the liquid for self-cleaning, thus improving the thoroughness of self-cleaning.

[0065] In this design, the liquid outlet direction of the second spray component 130 is perpendicular to the side wall of the suction channel 110, which helps to increase the comprehensiveness of the liquid contact with the side wall of the suction channel 110 and improve the cleaning effect. Understandably, in this case, the second spray component 130 can be positioned as close as possible to the air inlet 112 of the suction channel 110 to reduce the distance between the liquid landing point and the air inlet 112, and to maximize the length of the liquid flow path within the suction channel 110, thereby improving the thoroughness of cleaning the suction channel 110. This ensures that the suction pipe from the liquid landing point to the recovery bin 230 inside the machine body 210 can be flushed by the liquid to achieve self-cleaning, thus improving the thoroughness of self-cleaning.

[0066] Furthermore, the liquid outlet direction of the second spray component 130 can be one, two, or more, such as the liquid outlet direction of the second spray component 130 can be towards the air inlet 112 of the suction channel 110, towards the air outlet 113 of the suction channel 110, or one, two, or three perpendicular to the side wall of the suction channel 110.

[0067] The second spraying component 130 can spray in an umbrella-like, columnar, radial, or other regular or irregular shape. Specifically, Figure 6 The dashed arrow in the figure indicates the spray direction of the second spray assembly 130.

[0068] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the cleaning brush head 100 further includes: a brush handle 180 and a brush head 190. The brush handle 180 is provided with a suction channel 110. The brush head 190 is connected to the first end of the brush handle 180 and communicates with the suction channel 110. The second end of the brush handle 180 is configured to be connected to the machine body 210 of the cleaning device 200. The first spraying component 120, the second spraying component 130, the shifting mechanism 140, and the liquid inlet pipe 150 are provided on the brush handle 180.

[0069] In this embodiment, the brush handle 180 connects the brush head 190 and the main body 210 of the cleaning device 200. The brush handle 180 is provided with a suction channel 110, which communicates with the brush head 190 and the suction fan on the main body 210. Specifically, the brush head 190 may be provided with an air inlet channel communicating with the suction channel 110. The main body 210 is provided with a suction pipe communicating with the suction channel 110 and the collection bin 230, which is connected to the suction fan. In this way, when the suction fan of the cleaning device 200 is working, the dirt and liquid on the surface to be cleaned are carried by the negative pressure airflow through the air inlet channel of the brush head 190, through the suction channel 110 of the brush handle 180, and through the suction pipe on the main body 210 to be collected in the collection bin 230, thereby realizing the cleaning operation of the surface to be cleaned.

[0070] Furthermore, when the first spray assembly 120 and the second spray assembly 130 are not spraying liquid, the suction fan operates, which carries the dirt on the surface to be cleaned through the negative pressure airflow from the air inlet channel of the brush head 190, through the suction channel 110 of the brush handle 180, and through the suction pipe of the machine body 210 to the collection bin 230, thereby achieving a dry cleaning operation. When the first spray assembly 120 is spraying liquid, the suction fan operates, which carries the dirt and liquid on the surface to be cleaned through the negative pressure airflow from the air inlet channel of the brush head 190, through the suction channel 110 of the brush handle 180, and through the suction pipe of the machine body 210 to the collection bin 230, thereby achieving a wet cleaning operation. This expands the functionality of the cleaning brush head 100 and the cleaning device 200, realizing the diversification of the functions of the cleaning brush head 100 and the cleaning device 200.

[0071] Furthermore, the brush head 190 can directly contact the surface to be cleaned, rubbing it to remove stubborn substances and improve cleaning effectiveness. Specifically, for example... Figure 2 and Figure 3 As shown, the brush head 190 may be provided with an active part 191 that contacts and rubs against the surface to be cleaned. The active part 191 may be bristles, rubber protrusions, etc.

[0072] Furthermore, the brush head 190 and the brush handle 180 can be detachably connected, facilitating disassembly and separation for maintenance and replacement. This simplifies operation, improves maintenance efficiency, and saves on replacement costs. Specifically, the brush head 190 and the brush handle 180 can be detachably connected using at least one of the following methods: snap-fit ​​structure, plug-in structure, tenon and mortise structure, magnetic structure, and bolt structure. It is understood that in some embodiments, the brush head 190 and the brush handle 180 can also be fixedly connected or be an integral structure.

[0073] Furthermore, such as Figure 1As shown, the cleaning brush head 100 also includes a protective cover 192, which can be placed over the brush head 190. The protective cover 192 provides good protection for the brush head 190, preventing dirt from coming into contact with other objects and causing contamination. Specifically, when the cleaning brush head 100 is not in use, it can be stored by covering it with the protective cover 192. When the cleaning brush head 100 needs to be used, the protective cover 192 can be removed from the brush head 190, allowing the cleaning brush head 100 to be used for cleaning or self-cleaning operations.

[0074] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the brush handle 180 includes a handle body 181 and a cover plate 182. The handle body 181 is configured as a hollow structure to form a suction channel 110. An installation notch 183 is provided on one side of the handle body 181. The cover plate 182 is connected to the handle body 181 and covers the installation notch 183. The first spraying assembly 120, the second spraying assembly 130, the shifting mechanism 140, and the push switch 160 are installed in the installation notch 183. Therefore, by installing the first spray assembly 120, the second spray assembly 130, the shifting mechanism 140, and the push switch 160 within the space enclosed by the handle body 181 and the cover plate 182, the first spray assembly 120, the second spray assembly 130, the shifting mechanism 140, and the push switch 160 are effectively protected. This helps reduce the possibility of dirt and sludge contaminating the above-mentioned components and reduces the possibility of damage caused by collisions with external objects. It also helps extend the service life of the first spray assembly 120, the second spray assembly 130, the shifting mechanism 140, and the push switch 160.

[0075] Among them, such as Figure 2 As shown, the cover plate 182 is provided with a first clearance hole 185 to avoid the second nozzle 122 of the first spray assembly 120, thereby allowing the liquid to be smoothly sprayed onto the surface to be cleaned through the second nozzle 122 of the first spray assembly 120. Specifically, the spray direction of the first spray assembly 120 can be umbrella-shaped, columnar, radial, or other regular or irregular shapes. It is understood that the first spray assembly 120 includes a second liquid inlet 123, which can be located within the space enclosed by the cover plate 182 and the handle body 181. The second liquid inlet 123 can be connected to the switching valve of the shifting mechanism 140 through a pipeline.

[0076] The cover plate 182 is provided with a second clearance hole 186 to avoid the shift mechanism 140. If the cover plate 182 is provided with a second clearance hole 186, the operating part 141 of the shift mechanism 140 is exposed to the second clearance hole 186 and can move within the second clearance hole 186, so that the user can contact the operating part 141 through the second clearance hole 186 to perform the switching operation of the first gear and the second gear.

[0077] The cover plate 182 is provided with a third clearance hole 187 to avoid the push switch 160. If the cover plate 182 is provided with a third clearance hole 187, the pressing part 162 of the push switch 160 is exposed in the third clearance hole 187, so that the user can contact the pressing part 162 through the third clearance hole 187 to press the pressing part 162.

[0078] like Figure 1 As shown, embodiments of this application also provide a cleaning device 200, including: a machine body 210, and a cleaning brush head 100 of any of the foregoing embodiments. Since the cleaning device 200 includes the aforementioned cleaning brush head 100, it has all the effects of the aforementioned cleaning brush head 100, which will not be described in detail here.

[0079] In some possible embodiments provided in this application, the cleaning brush head 100 is detachably connected to the machine body 210. This facilitates the disassembly and separation of the cleaning brush head 100 from the machine body 210 for maintenance, replacement, and other operations, thereby improving maintenance efficiency and saving replacement costs.

[0080] Furthermore, the cleaning brush head 100 and the machine body 210 can be detachably connected via at least one of the following structures: snap-fit ​​structure, plug-in structure, tenon and mortise structure, magnetic structure, and bolt structure. Specifically, the machine body 210 and the brush handle 180 of the cleaning brush head 100 are detachably connected.

[0081] like Figure 1 As shown, in some possible embodiments provided in this application, the cleaning device 200 further includes: a liquid storage section 220, a recycling bin 230, and an air suction fan disposed on the machine body 210. When the cleaning brush head 100 is connected to the machine body 210, the liquid storage section 220 is connected to the liquid inlet pipe 150 of the cleaning brush head 100. The recycling bin 230 is provided with a sludge inlet and an exhaust outlet. The sludge inlet is connected to the sludge suction channel 110 of the cleaning brush head 100 through a sludge suction pipe. The exhaust outlet is connected to the air inlet of the air suction fan, and the air outlet of the air suction fan is connected to the external environment.

[0082] When cleaning is required, the user manually operates the operating section 141 of the shift mechanism 140 to put the shift mechanism 140 into the first gear position. The cleaning brush head 100 and the cleaning device 200 are in cleaning mode. At this time, the liquid inlet pipe 150 is connected to the first liquid spraying assembly 120. The suction fan operates, causing dirt or dirt and liquid on the surface to be cleaned to flow into the collection bin 230 through the suction channel 110 of the cleaning brush head 100 and the suction pipe of the machine body 210 under negative pressure airflow for collection. Then, the negative pressure airflow flows through the collection bin 230 and is discharged to the external environment through the exhaust port and the suction fan, thus completing the cleaning operation on the surface to be cleaned.

[0083] Furthermore, in the first position, the user can manually operate the press switch 160 to turn on the liquid pump. At this time, the liquid in the liquid storage section 220 is supplied to the first spray assembly 120 through the liquid inlet pipe 150, spraying the liquid onto the surface to be cleaned. Simultaneously, the suction fan works, causing the dirt and liquid on the surface to be cleaned to flow into the collection bin 230 for collection by the negative pressure airflow through the suction channel 110 of the cleaning brush head 100 and the suction pipe of the machine body 210. Then, the negative pressure airflow flows through the collection bin 230 and is discharged to the external environment through the exhaust port and the suction fan, realizing the wet cleaning operation on the surface to be cleaned. It can be understood that after the wet cleaning operation is completed, the user can manually operate the press switch 160 to turn off the liquid pump, the first spray assembly 120 stops spraying liquid, and the suction fan stops working.

[0084] In other words, in the first position, the user can switch the working state of the liquid pump by pressing the switch 160, so that the first spray component 120 sprays liquid or does not spray liquid. When the first spray component 120 does not spray liquid, dry cleaning operation can be performed. When the first spray component 120 sprays liquid, wet cleaning operation can be performed.

[0085] When self-cleaning is required, the user manually operates the operating part 141 of the shift mechanism 140 to put the shift mechanism 140 into the second gear position, and the cleaning brush head 100 and cleaning equipment 200 are in self-cleaning mode. At this time, the liquid inlet pipe 150 is connected to the second spraying assembly 130, the suction fan is working, and the user manually operates the press switch 160 to start the liquid pump. At this time, the liquid in the storage section 220 is supplied to the second spraying assembly 130 through the liquid inlet pipe 150 and sprayed into the inside of the suction channel 110. The liquid in the suction channel 110 flows into the collection bin 230 for collection by the negative pressure airflow through the suction channel 110 of the cleaning brush head 100 and the suction pipe of the machine body 210. Then, the negative pressure airflow flows through the collection bin 230 and is discharged to the external environment through the exhaust port and the suction fan. During this process, the liquid washes the path it flows through from the point of impact, achieving self-cleaning of the suction channel 110 of the cleaning brush head 100 and the suction pipe of the machine body 210, as well as some pipes of the cleaning brush head 100 and the cleaning equipment 200. After the self-cleaning operation is completed, the user manually operates the press switch 160 to turn off the liquid pump, the second spray component 130 stops spraying liquid, and the suction fan stops working. The whole process is simple and easy to operate, with clear logic, allowing customers to operate it blindly.

[0086] The cleaning brush head 100 provided in this embodiment adopts a modular design and is designed as a replaceable brush head 190 structure. It does not require modification of the original structure of the machine body 210. After docking and connecting with the machine body 210, it can directly complete the self-cleaning operation of the suction channel 110 of the cleaning brush head 100 and the suction pipe in the machine body 210. It is fast, time-saving, convenient and quick to maintain, and has low noise. The user learning cost is low, which can significantly improve user satisfaction and user experience, and is suitable for widespread application.
