[0057] Cleaning equipment typically comes with a handheld cleaning head, which can be used to remove dust and clean surfaces. A handheld cleaning head generally consists of a nozzle body and a detachable dust cover attached to the nozzle body, forming a dust collection channel between them. To ensure the dust collection channel remains clear, the dust cover needs to be periodically removed from the nozzle body for cleaning. However, in some technologies, removing the dust cover also separates the nozzle body from the handle, requiring reconnection of the nozzle body and handle when reinstalling the dust cover, increasing the complexity of subsequent operations and affecting the efficiency of installation and removal.

[0058] Based on this, one embodiment of this application provides a cleaning head that can improve disassembly and assembly efficiency. The cleaning head provided in one embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0059] See Figures 1A to 3 as well as Figures 6 to 10 As shown, an embodiment of this application provides a cleaning head including a nozzle body 100, a dust cover 200, and a handle 300. The nozzle body 100 is provided with a first mating part 120 and a first dial part 110; the dust cover 200 is provided with a second mating part 210; and the handle 300 is provided with a first snap-fit ​​part 310. When the first dial part 110 is in the locked position, the first dial part 110 is connected to the second mating part 210, and the first snap-fit ​​part 310 can be sequentially connected to the first mating part 120 and the second mating part 210 to connect the nozzle body 100 and the dust cover 200 to the handle 300. The first dial part 110 is configured to be operablely toggled to move from the locked position to a first unlocked position. When the first dial part 110 is in the first unlocked position, it can press against the first snap-fit ​​part 310 to disengage the first snap-fit ​​part 310 from the second mating part 210, while the first snap-fit ​​part 310 remains connected to the first mating part 120.

[0060] By setting the first toggle switch 110 on the nozzle body 100, when it is necessary to remove the dust cover 200, along... Figure 1B Move the first toggle switch 110 in the direction of the arrow shown, so that the first toggle switch 110 presses against the first latching part 310. At this time, it can be moved along... Figure 1BPushing the dust cover 200 in the direction of the arrow indicates that the dust cover 200 will act on the first dial part 110, thereby causing the first dial part 110 and the first locking part 310 to move downwards in a direction perpendicular to the arrow. This disengages the first locking part 310 from the second mating part 210 on the dust cover 200, while the first locking part 310 and the first mating part 120 remain connected. That is, the handle 300 and the nozzle body 100 remain connected. Thus, after removing the dust cover 200, there is no need to reconnect the handle 300 and the nozzle body 100. The dust cover 200 can be directly reassembled after cleaning, avoiding the hassle of reconnecting the handle 300 after removing the dust cover 200 from the nozzle body 100. This simplifies the operation process, reduces the complexity of subsequent operations, and improves disassembly and assembly efficiency. Meanwhile, since frequent connection between the handle 300 and the nozzle body 100 is not required after removing the dust cover 200, the risk of wear between the handle 300 and the nozzle body 100 is significantly reduced, helping to extend the service life of the handle 300 and the nozzle body 100, thereby ensuring the stability and reliability of the cleaning head in use. In other embodiments, it can also be along... Figure 1B The arrow indicates that the first toggle switch 110 is toggled in the direction indicated, causing the first toggle switch 110 to... Figure 1B Rotating clockwise in the view shown, thereby pressing against the first locking part 310 and causing the first locking part 310 to move downward, so that the first locking part 310 disengages from the second mating part 210.

[0061] like Figure 1B and Figure 10 As shown, it can be understood that when the first dial portion 110 is in the locked position, the first dial portion 110 protrudes from the outer surface of the dust cover 200 and the handle 300, making it convenient for the user to move the first dial portion 110. In some embodiments, the first locking portion 310 is provided with a protruding locking block, and the first mating portion 120 and the second mating portion 210 can be locking grooves for engaging with the locking block. In some embodiments, the first locking portion 310 may also be provided with a receiving groove, and when the nozzle body 100 is connected to the handle 300, a portion of the first dial portion 110 is located in the receiving groove.

[0062] See Figure 1B , Figures 8 to 12 As shown, in one embodiment, the sidewall of the second mating portion 210 is constructed with a guide slope 211, and the first toggle portion 110 is constructed with a mating slope 111 for sliding engagement with the guide slope 211. Thus, along... Figure 1BWhen the dust cover 200 is pushed in the direction of the arrow, the sliding engagement between the guide slope 211 on the dust cover 200 and the mating slope 111 of the first dial part 110 converts the movement of the dust cover 200 in the direction of the arrow into a downward movement of the first dial part 110 in a direction perpendicular to the arrow. This causes the first dial part 110 to drive the first locking part 310 downward, thus disengaging the first locking part 310 from the first mating part 120. Simultaneously, when installing the dust cover 200, the installation direction of the dust cover 200 is... Figure 1B In the opposite direction of the arrows shown, the movement of the dust cover 200 can be guided by the sliding engagement of the guide slope 211 and the mating slope 111, so that the first knob part 110 passes through the second mating part 210 and the first snap-fit ​​part 310 passes through the second mating part 210, thereby realizing the connection of the dust cover 200, the nozzle body 100 and the handle 300.

[0063] See Figure 8 As shown, in some embodiments, the first toggle part 110 is provided with a first limiting protrusion 112. When the first toggle part 110 is in the locked position, the first limiting protrusion 112 prevents the first toggle part 110 from disengaging from the second mating part 210. Thus, before removing the dust cover 200, it is necessary to first follow... Figure 8 The arrow indicates that the first dial 110 is toggled in the direction of the first arrow, placing it in the unlocked position. This means the first limiting protrusion 112 is no longer directly above the surface of the dust cover 200, and it will not interfere with the movement of the dust cover 200, thus facilitating its removal. In other words, by setting the first limiting protrusion 112, the connection reliability between the first dial 110 and the second mating part 210 is improved, which in turn improves the connection reliability between the nozzle body 100 and the dust cover 200, reducing the possibility of the dust cover 200 disintegrating due to misoperation.

[0064] See Figure 6 As shown, in one embodiment, the outer surface of the dust cover 200 is provided with a protruding removal portion 220; when the first toggle switch 110 is in the first unlocked position, the removal portion 220 is configured to be operably pushed to disengage the dust cover 200 from the nozzle body 100. Figure 6 As shown, the arrows indicate the pushing direction of the removal part 220. By providing the protruding removal part 220 on the dust cover 200, a force application position is provided for the user, making it convenient for the user's fingers to apply force to the removal part 220 to push the dust cover 200 to move, so that the first snap-fit ​​part 310 and the second mating part 210 are separated, which facilitates the disassembly operation of the dust cover 200 and reduces hand fatigue.

[0065] See Figure 6As shown, in one embodiment, the removal part 220 protrudes from the first dial part 110. With this design, on the one hand, the removal part 220 can provide a certain shielding effect on the first dial part 110, preventing the risk of the dust cover 200 accidentally falling off due to the user accidentally touching the first dial part 110; on the other hand, it can help the user quickly and accurately distinguish between the removal part 220 and the first dial part 110, improving disassembly efficiency.

[0066] See Figure 10 As shown, in some embodiments, the pushing surface 221 of the removal part 220 is inclined relative to the outer surface of the dust cover 200. That is, the pushing surface 221 is an inclined surface. On the one hand, the inclined surface design can intuitively guide the user to apply force in the correct direction, reducing the possibility of misoperation. Moreover, the inclined surface design allows the user's fingers to be placed naturally on the removal part 220, providing a more ergonomic operating angle. On the other hand, the inclined surface provides a larger contact area, which can evenly distribute the pressure at the point of force application, making the disassembly process more effortless.

[0067] See Figure 7 As shown, in one embodiment, one of the dust cover 200 and the nozzle body 100 is provided with a positioning part 140, and the other is provided with a positioning hole 240 for engaging with the first positioning part 140. For example, in the embodiment shown in the figure, the positioning part 140 is provided at the end of the nozzle body 100 away from the handle 300, and the positioning hole 240 is provided at the end of the dust cover 200 away from the handle 300. The engaging cooperation between the positioning part 140 and the positioning hole 240 further enhances the connection effect between the dust cover 200 and the nozzle body 100, ensuring a stable connection between the two and improving the reliability of the cleaning equipment. In other embodiments, the positions of the positioning part 140 and the positioning hole 240 can be interchanged. It can be understood that the extending direction of the positioning part 140 and the positioning hole 240 is parallel to the disassembly direction of the dust cover 200.

[0068] In one embodiment, an elastic element (not shown) connects the handle 300 and the first latching portion 310. Understandably, when the first dial portion 110 is in the locked position, i.e., when the first latching portion 310 is not subjected to external force, the elastic element is in its natural state. When the user applies force to the first dial portion 110 to disengage the first latching portion 310 from the second mating portion 210, the elastic element is in a deformed state. By providing the elastic element, a reset locking force is provided to the first latching portion 310, allowing it to automatically reset after the external force is removed, so as to connect with at least one of the first mating portion 120 and the second mating portion 210, ensuring the reliable connection between the handle 300, the nozzle body 100, and the dust cover 200. In some embodiments, the elastic element can be a spring.

[0069] See Figure 1B and Figure 2B As shown, in one embodiment, the first engaging portion 310 includes a fixing section 311, a latching section 313, and an unlocking section 314. The fixing section 311 is connected to the handle 300, and the latching section 313 is used to connect with the first engaging portion 120 and the second engaging portion 210. One of the latching section 313 and the unlocking section 314 is connected to an elastic member. In response to the unlocking operation of the unlocking section 314, the latching section 313 can move to a second unlocking position to disengage from the first engaging portion 120. In the embodiment shown in the figures, the elastic member is connected to the unlocking section 314, that is, the elastic member is located below the unlocking section 314. In other embodiments, the elastic member may also be connected to the latching section 313, that is, the elastic member is located below the latching section 313. Understandably, the fixed section 311 remains in the same position relative to the handle 300. By setting the unlocking section 314, a force application position is provided for the user, allowing the user to apply force to the unlocking section 314 so that the latching section 313 can move down to disengage from the first mating part 120, thereby releasing the connection between the nozzle body 100 and the handle 300.

[0070] In some embodiments, when the user applies the unlocking section 314 to move the latching section 313 to the second unlocking position and disengage it from the first engaging part 120, the first toggle part 110 can still be engaged in the second engaging part 210 of the dust cover 200, meaning that the dust cover 200 and the nozzle body 100 still have a certain connection effect. Thus, when the nozzle body 100 and the handle 300 are disconnected, the dust cover 200 and the nozzle body 100 will not fall apart, reducing the risk of damage caused by accidental drop of the dust cover 200 or the nozzle body 100.

[0071] See Figure 1B and Figure 2BAs shown, in one embodiment, the latching segment 313 is located between the fixed segment 311 and the unlocking segment 314. In response to a pressing operation of the unlocking segment 314, the latching segment 313 can disengage from the first mating part 120. That is, the latching segment 313 and the unlocking segment 314 are located on the same side of the fixed segment 311. Thus, when the user presses down on the unlocking segment 314, the latching segment 313 will move downwards and disengage from the first mating part 120. If the first engaging part 310 is considered a lever structure, then the fixed segment 311 corresponds to the fulcrum end of the lever structure, and the unlocking segment 314 and the latching segment 313 correspond to the power end and resistance end, respectively. Since the latching segment 313 is located between the fixed segment 311 and the unlocking segment 314, i.e., the resistance arm is smaller than the power arm, the user only needs to apply a small force to the unlocking segment 314 to generate a large output force on the latching segment 313. This makes disassembly between the handle 300 and the nozzle body 100 easier and reduces user fatigue. In other embodiments, the latching section and the unlocking section may be located on opposite sides of the fixed section. In this way, by lifting the unlocking section upwards, the latching section can be moved downwards to disengage from the first mating part.

[0072] See Figure 1B and Figure 2B As shown, in one embodiment, at least one of the handle 300 and the unlocking segment 314 is provided with a first fixing part 333, which is used to fix the elastic member. In the embodiment shown in the figure, both the handle 300 and the unlocking segment 314 are provided with the first fixing part 333, wherein the first fixing part 333 can be a protruding limiting post or a recessed limiting groove. For example, in the embodiment shown in the figure, the unlocking segment 314 is provided with a limiting groove, the handle 300 is provided with a limiting post, one end of the elastic member is accommodated in the limiting groove, and the other end is sleeved on the limiting post. By setting the first fixing part 333 to limit the elastic member, the deformation direction of the elastic member is effectively constrained, thereby ensuring the reliability of the direction of the restoring force applied by the elastic member. In other embodiments, the first fixing part 333 may only be provided on one of the handle 300 and the unlocking segment 314 to limit one end of the elastic member, and the other end of the elastic member may be welded to the other of the handle 300 and the unlocking segment 314, which can be set according to actual needs.

[0073] See Figure 1B and Figure 2BAs shown, in some embodiments, the latching segment 313 is located between the fixed segment 311 and the unlocking segment 314. The first latching portion 310 also includes a bent segment 312 located between the fixed segment 311 and the latching segment 313, extending from the fixed segment 311 in a direction close to the elastic member. The bent segment 312 can provide a certain elastic deformation capacity, allowing the latching segment 313 to be finely adjusted in position as needed during insertion and removal, ensuring a tight fit with the first mating portion 120 and the second mating portion 210. Simultaneously, the bent segment 312 can also disperse the force applied to the latching segment 313, avoiding stress concentration. Furthermore, because the bent segment 312 provides better elasticity and recovery capacity, the latching segment 313 is less prone to permanent deformation or fracture during repeated use, exhibiting high fatigue strength. For example, in the embodiment shown in the figures, the bent segment 312 is U-shaped. The unlocking section 314 and the latching section 313 are designed as protruding latches. The shape and size of the latches can be set according to actual needs. For example, the protrusion height of the unlocking section 314 is greater than the protrusion height of the latching section 313. An accommodating groove for accommodating the first toggle part 110 is formed between the unlocking section 314 and the latching section 313.

[0074] See Figure 2B As shown, in some embodiments, the handle 300 is provided with a support structure 330 for supporting the first latching portion 310. The support structure 330 provides additional support points for the first latching portion 310, reducing the risk of loosening due to vibration or external forces, and ensuring a more secure connection between the first latching portion 310 and the nozzle body 100 and dust hood 200. Simultaneously, it allows the force on the first latching portion 310 to be more evenly distributed across the entire support structure 330, reducing localized stress concentration and thus lowering the risk of wear and fatigue damage.

[0075] See Figure 2BAs shown, in one embodiment, the support structure 330 includes a support plate 331 and a support column 332 protruding from the support plate 331. The aforementioned first fixing part 333, which is provided on the handle 300, can be located on the support plate 331, and the aforementioned fixing section 311 can be connected to the support column 332. In some embodiments, at least one of the support column 332 and the fixing section 311 is provided with a connecting hole 3111, and the other is connected with a connector for insertion into the connecting hole 3111. For example, in the embodiment shown in the figures, both the support column 332 and the fixing section 311 are provided with connecting holes 3111, and the connector passes through the connecting holes 3111 of both, thereby fixing the support column 332 and the first snap-fit ​​part 310. For example, the connecting hole 3111 is a pin hole, and the connector is a pin; or the connecting hole 3111 is a screw hole, and the connector is a screw, etc. In other embodiments, one of the support column 332 and the fixing section 311 may be configured with a connecting hole 3111, and the other may be configured with a connector that is inserted into the connecting hole 3111.

[0076] See Figures 1B to 4 As shown, in one embodiment, the nozzle body 100 is provided with a marking portion 191, and the handle 300 is provided with an identification portion 320 for identifying the marking portion 191. The marking portion 191 stores type information of the nozzle body 100. When the nozzle body 100 is connected to the handle 300, the identification portion 320 can identify the marking portion 191, causing the cleaning device to enter a cleaning mode matching the nozzle body 100. Specifically, by identifying the marking portion 191 through the identification portion 320, a signal is transmitted to the control unit of the cleaning device. The control unit can identify the type information of the nozzle body 100 based on this signal, and then adjust the cleaning mode of the cleaning device according to the type information, such as adjusting the suction force, suction power, or the temperature of the sprayed cleaning source, to match the actual usage scenario.

[0077] See Figure 1B and Figure 2B As shown, in one embodiment, one of the marking part 191 and the identification part 320 is configured as a male connector, and the other is configured as a female connector for connection with the male connector. For example, the marking part 191 is a male connector and the identification part 320 is a female connector; of course, the marking part 191 can also be a female connector and the identification part 320 can be a male connector. In some embodiments, the male connector can be a pin, and the female connector can be a pin connection hole 3111. When the nozzle body 100 is connected to the handle 300, the pin of the nozzle body 100 is connected to the pin connection hole 3111 on the handle 300, and the information on the marking part 191 is read through the physical contact between the two to realize signal transmission.

[0078] In other embodiments, the tagging unit 191 can be a short-range communication module such as a QR code, NFC, RFID, or Bluetooth, and the identification unit 320 can be a reader or a receiver. For example, when the tagging unit 191 is a QR code, the identification unit 320 can use a camera or barcode scanner as a reader to read information and transmit signals; when the tagging unit 191 is NFC, the identification unit 320 can use a card reader as a reader; when the tagging unit 191 is RFID, the identification unit 320 can use an RFID reader as a reader; when the tagging unit 191 is Bluetooth, the identification unit 320 can use a Bluetooth receiver as a reader to read information and transmit signals.

[0079] See Figure 1B or Figure 13B As shown, in one embodiment, the nozzle body 100 is configured with a first suction channel 130, a portion of which is inclined relative to the outer surface of the nozzle body 100. By inclining the portion of the first suction channel 130, abrupt changes in air direction within the channel can be reduced, avoiding unnecessary vibration and noise, and also helping to reduce friction and turbulence during airflow. Simultaneously, gravity can be used to help heavier particles slide down the channel, allowing the sucked-in air and particles to pass more smoothly, reducing the possibility of particle accumulation within the channel. Furthermore, it also reduces the risk of sucked-in particles flowing back to the surface being cleaned due to airflow changes, preventing contamination of the cleaned surface and ensuring a more thorough cleaning effect. For example, in the embodiment shown in the attached figures, the first suction channel 130 is in an inclined L-shape.

[0080] See Figure 1B or Figure 13B As shown, in one embodiment, the dust hood 200 is configured with a negative pressure port 230. After the nozzle body 100 and the dust hood 200 are connected, a negative pressure channel is formed between them, communicating with the negative pressure port 230. The negative pressure channel is connected to the first suction channel 130. The flow area of ​​the negative pressure port 230 is smaller than the flow area of ​​the first suction channel 130. When the gas flow rate is constant, the flow area is inversely proportional to the fluid velocity. By setting the flow area of ​​the negative pressure port 230 to be smaller than the flow area of ​​the first suction channel 130, the flow velocity at the negative pressure port 230 can be increased, meaning a stronger negative pressure zone can be formed at the negative pressure port 230. This helps to quickly suck in surrounding dust and particles, improving cleaning efficiency. Simultaneously, it also reduces the problem of wastewater flowing back from the negative pressure port 230 to the cleaned surface, preventing contamination of the cleaned surface. In some embodiments, the flow area of ​​the negative pressure port 230 is less than 20% of the flow area of ​​the first suction channel 130.

[0081] See Figures 13A to 14As shown, in one embodiment, the nozzle body 100 has an opening 180, and an air inlet 170 is constructed on the edge of the outer peripheral surface of the nozzle body 100 near the opening 180. This allows air to enter the system from multiple directions, increasing the airflow inlet area and facilitating the collection of surrounding dust and debris to the negative pressure port 230, expanding the cleaning range and preventing secondary pollution; it also disperses airflow pressure, reduces local resistance, and thus improves overall suction efficiency.

[0082] See Figures 13B to 15 As shown, in some embodiments, the nozzle body 100 has an opening 180, within which a brush holder 182 is disposed. Multiple tufts of bristles 181 are mounted on the brush holder 182, extending out of the opening 180 in a direction away from the handle 300, with an extension length of 1mm-3mm. In some embodiments, the brush holder 182 has multiple brush mounting holes 185, each with bristles 181 mounted on it. The protruding bristles 181 can better contact and penetrate into the texture or crevices of the surface being cleaned, such as carpet fibers and floor seams, removing stubborn stains and dust through physical friction, thus improving cleaning effectiveness. Furthermore, the bristles 181 help disperse airflow, allowing it to more evenly cover the entire cleaning area, improving cleaning efficiency. Furthermore, the protruding bristles 181 allow for a certain gap between the negative pressure port 230 and the surface being cleaned, thus providing a certain air intake. Therefore, additional air inlets 170 can be opened as needed, or no additional air inlets 170 can be provided.

[0083] In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 1 mm. In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 2.5 mm. In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 3 mm. In other embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can also be other values, which will not be listed here. Bristles 181 of different lengths can adapt to surfaces of different shapes and materials being cleaned, ensuring effective cleaning on various surfaces without damaging their appearance.

[0084] See Figure 1B , Figures 13B to 15As shown, in some embodiments, the nozzle body 100 has an opening 180, within which a brush holder 182 is disposed. The brush holder 182 is provided with bristles 181, a steam injection hole 183, and a suction port 184. The steam injection hole 183 is directly disposed on the brush holder 182, that is, on the nozzle body 100. Therefore, after the nozzle body 100 is connected to the handle 300, only the sealing effect between the first steam channel 150 and the second steam channel 340 needs to be considered, which can reduce the number of sealing positions and sealing costs. High-temperature steam is released through the steam injection hole 183 to soften stains, while the bristles 181 located thereafter further decompose and remove stubborn stains through physical friction. Afterwards, the suction port 184 can quickly suck the loose dirt into the cleaning device, forming an effective cleaning cycle. By setting a dedicated suction port 184 on the nozzle body 100 and combining it with the negative pressure port 230 on the dust cover 200, suction can be generated at different locations, enabling the cleaning equipment to simultaneously suck up dirt from multiple directions, ensuring more comprehensive cleaning coverage. It can also make the airflow more evenly distributed in the cleaning area, avoiding over-cleaning or damage to the surface in some areas due to excessively concentrated airflow.

[0085] See Figure 1B , Figures 13B to 15 As shown, it can be understood that the steam injection port 183 is connected to the first steam channel 150 of the nozzle body 100, and the suction port 184 is connected to the first suction channel 130 of the nozzle body 100; when the nozzle body 100 and the handle 300 are connected, the first steam channel 150 is connected to the second steam channel 340 of the handle 300; the first suction channel 130 is connected to the second suction channel 350 of the handle 300. Thus, the cleaning source provided by the cleaning source supply unit in the cleaning equipment can sequentially pass through the second steam channel 340 and the first steam channel 150, and then be sprayed onto the surface to be cleaned through the steam injection port 183; the cleaned dirt, under the action of negative pressure suction, enters the first suction channel 130 through the negative pressure port 230 and the suction port 184, and then enters the dirt recovery unit of the cleaning equipment through the second suction channel 350. The flow area of ​​the suction port 184 is smaller than the fluid area of ​​the first suction channel 130. The smaller flow area of ​​the suction port 184 reduces the risk of wastewater flowing back to the surface being cleaned, preventing contamination of the fabric surface. At the same time, for particularly dirty or hard-to-clean areas, the smaller flow area of ​​the suction port 184 provides stronger localized suction, helping to more effectively remove stubborn stains or large pieces of debris.

[0086] See Figure 1B , Figures 13B to 15As shown, in some embodiments, the bristles 181 are located between the steam jet hole 183 and the suction port 184. By positioning the bristles 181 between the steam jet hole 183 and the suction port 184, the bristles 181 can help guide the steam ejected from the steam jet hole 183 to a specific area, ensuring that the cleaning medium can directly act on the area that needs cleaning. Simultaneously, after the cleaning source is sprayed onto the surface being cleaned, it flows through the bristles 181 and then into the suction port 184, thereby removing dirt from the bristles 181, achieving self-cleaning of the bristles 181, reducing the possibility that dirt on the bristles 181 may affect the subsequent cleaning effect. Furthermore, the bristles 181 can help accelerate moisture evaporation after steam cleaning, speeding up the drying process.

[0087] Furthermore, one embodiment of this application also provides a cleaning device (not shown), including the cleaning head described in any of the above embodiments. It is understood that the cleaning device further includes a cleaning source supply unit (not shown) and a waste collection unit (not shown). The cleaning source supply unit provides a cleaning source to the surface to be cleaned through the cleaning head, thereby cleaning the stains on the surface. The cleaned waste enters the waste collection unit through a negative pressure port under the action of negative pressure suction, so as to absorb the cleaned waste. It is understood that when the nozzle body is also provided with a suction port, waste can also enter the waste collection unit through the suction port.

[0088] In one embodiment, the cleaning source includes at least one of water vapor, water, and a solution containing detergent, which can be selected by those skilled in the art according to actual needs. When water vapor is used as the cleaning source, the cleaning equipment also includes a steam generator (not shown), which generates high-temperature, high-pressure water vapor from clean water and sprays it onto the surface to be cleaned through steam injection holes. In one embodiment, the steam generator can be a heater. By using water vapor as the cleaning source, the high temperature of the water vapor, while being directly injected, can also accelerate the dissolution of stains, further improving the cleaning effect. When water or a solution containing detergent is used as the cleaning source, the injection pressure can be increased, improving the injection force, which is more effective for cleaning larger volumes of dirt.

[0089] In a practical application scenario, cleaning equipment can be a steam cleaner, carpet cleaner, floor scrubber, cleaning robot, vacuum cleaner, high-pressure washer, or medical disinfection and cleaning equipment. The cleaning source supply unit in the cleaning equipment provides the cleaning source to the surface being cleaned through the cleaning head, thus cleaning the stains on the surface. After cleaning, the dirt is collected by the negative pressure suction generated by the dirt recovery unit through the negative pressure port.

[0090] In one embodiment, the cleaning source supply unit includes a water pump and a clean water tank for holding the cleaning source. One end of the water pump is connected to the clean water tank via a pipeline, and the other end is connected to the nozzle of the cleaning head via a pipeline. The water pump is electrically connected to a controller, which controls the operation of the water pump to deliver the cleaning source in the clean water tank to the nozzle via the pipeline, and then sprays the cleaning source onto the surface to be cleaned through the nozzle.

[0091] In some embodiments, the waste collection unit includes a negative pressure suction device and a wastewater tank for holding waste. One end of the negative pressure suction device is connected to the wastewater tank via a pipeline, and the other end is connected to a negative pressure port. The negative pressure suction device is electrically connected to a controller, which controls the negative pressure suction device to perform suction operations, drawing the waste removed from the cleaning surface through the negative pressure port into the wastewater tank. In one embodiment, the negative pressure suction device can be a vacuum pump.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
