Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to cleaning components, cleaning heads, and cleaning devices. Background Technology

[0002] To better clean surfaces such as floors and carpets, wet surface cleaning equipment has emerged. This equipment is suitable not only for cleaning hard surfaces such as tile and hardwood, but also for cleaning soft surfaces such as carpets. Wet surface cleaning equipment typically consists of a cleaning head that sprays cleaning fluid onto the surface through nozzles, and then removes the cleaned liquid and debris (which may include grime, dust, stains, soil, hair, and other debris) through negative pressure outlets.

[0003] In related technologies, in order to improve the cleaning effect, the cleaning head is generally equipped with a cleaning component, which makes scraping contact with the surface being cleaned to improve the cleaning effect.

[0004] However, while cleaning the surface being cleaned, the aforementioned cleaning devices are also prone to picking up stains from the surface, which can affect the subsequent cleaning results. Utility Model Content

[0005] Therefore, it is necessary to provide a cleaning component that addresses the problem of poor cleaning performance in existing cleaning heads.

[0006] A cleaning component is applied to a cleaning head, the cleaning head including a negative pressure unit configured with a negative pressure channel; the cleaning component includes:

[0007] The cleaning body contacts the surface to be cleaned. The cleaning body is provided with a first negative pressure port, which is located on the inlet side of the negative pressure channel and is connected to the inlet of the negative pressure channel.

[0008] At least one first positioning part is disposed on the cleaning body; the first positioning part is used to be detachably connected to the negative pressure unit so that the cleaning body is connected to the negative pressure unit.

[0009] In one embodiment, the first positioning part is configured as a first positioning protrusion; along the fluid flow direction in the negative pressure channel, the size of the first positioning protrusion increases in a first direction, wherein the first direction is the direction from the side of the cleaning body away from the first positioning part to the side of the cleaning body facing the first positioning part.

[0010] In one embodiment, the first positioning protrusion includes a first connecting section and a first abutting section distributed along the fluid flow direction within the negative pressure channel;

[0011] The first abutting section abuts against the side of the negative pressure unit facing the cleaning body; the first connecting section and / or a portion of the first abutting section are used for detachable connection with the negative pressure unit.

[0012] In one embodiment, the dimension of the first abutting segment along the second direction is greater than the dimension of the first connecting segment along the second direction, wherein the second direction is perpendicular to the first direction and intersects with the fluid flow direction in the negative pressure channel.

[0013] In one embodiment, along the fluid flow direction in the negative pressure channel, a first stop is constructed at the end of the cleaning body near the first negative pressure port;

[0014] The first stop extends along a first direction to close the openings of the negative pressure channel distributed along a second direction.

[0015] A cleaning head includes a negative pressure unit and a cleaning component as described above; the negative pressure unit is configured with a first mating part, which engages with a first positioning part.

[0016] In one embodiment, the negative pressure unit includes a first negative pressure component and a second negative pressure component;

[0017] The first negative pressure component and the second negative pressure component cooperate to form the negative pressure channel; the first negative pressure component is constructed with the first mating part.

[0018] In one embodiment, the first positioning portion is configured as a first positioning protrusion, and the first mating portion is configured as a first positioning groove; the side of the second negative pressure member facing the first negative pressure member is configured with a first abutting protrusion, the first abutting protrusion being used to abut against the first positioning protrusion passing through the first positioning groove at least under negative pressure; and / or,

[0019] One of the first negative pressure component and the second negative pressure component is provided with a first sealing ridge, and the other is provided with a first sealing groove for engaging with the first sealing ridge.

[0020] In one embodiment, a first marking portion is provided at the end of the negative pressure unit away from the first negative pressure port; and / or,

[0021] One of the cleaning component and the negative pressure unit is provided with a second positioning part, and the other is provided with a second mating part for engaging with the second positioning part.

[0022] In one embodiment, the cleaning head includes a spray unit that sprays a cleaning source capable of covering at least a portion of the cleaning element.

[0023] In one embodiment, the cleaning head includes a first housing and a second housing connected to the first housing, the second housing cooperating with the first housing to enclose a first receiving cavity for receiving at least a portion of the cleaning component;

[0024] The second housing has a first connecting part at the end away from the first negative pressure port, which is used to detachably connect to the handle of the cleaning device.

[0026] A cleaning device includes a cleaning source supply unit, a waste collection unit, and a cleaning head as described above. The cleaning source supply unit provides a cleaning source to the surface to be cleaned through the cleaning head. The negative pressure unit is connected to the waste collection unit and is used to absorb the waste after cleaning.

[0027] The aforementioned cleaning component enhances cleaning effectiveness by scraping the surface being cleaned against the cleaning body. Because the cleaning body has a first negative pressure port located at the entrance of the negative pressure channel and connected to it, dirt can be sucked away through this port, reducing the possibility of stains remaining on the cleaning body. Furthermore, since the cleaning body is detachably connected to the negative pressure unit via a first positioning part, when the cleaning body becomes soiled, the component can be easily removed by disconnecting the first positioning part from the negative pressure unit, allowing for better cleaning and ensuring subsequent cleaning effectiveness. Additionally, because the cleaning component is detachably connected to the cleaning head, when it wears out or becomes damaged over time, it can be removed from the cleaning head and replaced individually, eliminating the need to replace the entire cleaning head and reducing replacement costs.

Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0039] To better clean surfaces such as floors and carpets, wet surface cleaning equipment has emerged. To enhance cleaning effectiveness, the cleaning head of wet surface cleaning equipment typically includes cleaning components that scrape against the surface to improve cleaning results. However, these cleaning components can easily pick up stains from the surface while cleaning, which can affect subsequent cleaning efforts. In related technologies, the cleaning components are usually thermoformed and fixed to the cleaning head, making it relatively difficult to remove stains from them.

[0040] Based on this, one embodiment of this application provides a cleaning component that can be easily removed from the cleaning head, thereby enabling better cleaning of the cleaning component and ensuring its subsequent cleaning effect. The cleaning component provided in one embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0041] See Figures 1 to 4 As shown, a cleaning component 100 provided in one embodiment of this application is applied to a cleaning head 10. The cleaning head 10 includes a negative pressure unit 300 with a negative pressure channel 430. The cleaning component 100 includes a cleaning body 110, which is used to contact the surface to be cleaned. A first negative pressure port 111 is provided on the cleaning body 110. The first negative pressure port 111 is located on the inlet side of the negative pressure channel 430 and communicates with the inlet of the negative pressure channel 430. At least one first positioning part 120 is also provided on the cleaning body 110. The first positioning part 120 is used to be detachably connected to the negative pressure unit 300 so that the cleaning body 110 is connected to the negative pressure unit 300.

[0042] The cleaning component 100 improves the cleaning effect on the surface being cleaned by scraping the cleaning body 110 against it. Since the cleaning body 110 is provided with a first negative pressure port 111 located on the inlet side of the negative pressure channel 430 and connected to the negative pressure channel 430, dirt can be sucked away through the first negative pressure port 111. The dirt enters the negative pressure channel 430 through the first negative pressure port 111, reducing the possibility of dirt residue on the cleaning body 110. At the same time, since the cleaning body 110 is detachably connected to the negative pressure unit 300 through the first positioning part 120, when the cleaning body 110 is stained, the cleaning component 100 can be easily removed by disconnecting the first positioning part 120 from the negative pressure unit 300, thereby enabling better cleaning of the cleaning component 100 and ensuring the subsequent cleaning effect of the cleaning component 100. Meanwhile, since the cleaning component 100 is detachably connected to the cleaning head 10, when the cleaning component 100, as a consumable, wears or is damaged as the usage time increases, the cleaning component 100 can be removed from the cleaning head 10 and replaced separately, thus eliminating the need to replace the entire cleaning head 10 and reducing replacement costs.

[0043] See Figure 1As shown, in some embodiments, the first negative pressure port 111 is semi-elliptical. Of course, in other embodiments, the first negative pressure port 111 can also be a regular shape such as a triangle, rectangle, polygon, or circle, or other irregular shapes; there are no specific limitations.

[0044] See Figure 1 As shown, in some embodiments, the first positioning portion 120 is configured as a first positioning protrusion 121; along the fluid flow direction within the negative pressure channel 430, the size of the first positioning protrusion 121 increases along a first direction. The first direction is the direction from the side of the cleaning body 110 away from the first positioning portion 120 towards the side of the cleaning body 110 facing the first positioning portion 120. For example... Figure 1 As shown in the figure, the first direction and fluid flow direction are illustrated. In some embodiments, taking the cleaning component 100 as a scraper as an example, the first direction can be the thickness direction of the cleaning component 100, and the thickness of the first positioning protrusion 121 can gradually increase, that is, the first positioning protrusion 121 is conical. In other embodiments, the thickness of the first positioning protrusion 121 can also increase abruptly, that is, the thickness of the first positioning protrusion 121 changes significantly at a certain position, rather than being a smooth transition. By setting the thickness variation of the first positioning protrusion 121, after the dirt is sucked into the first negative pressure port 111, the first positioning protrusion 121 can play a certain role in guiding the flow direction of the dirt, so that the dirt can enter the negative pressure channel 430 more smoothly, and prolong the movement path of the dirt, which helps to increase the contact time between the dirt and the airflow, and increases the probability of the dirt being carried away. Meanwhile, the first positioning protrusion 121 can divide the dirt, thereby reducing the risk of dirt clumping and remaining in the negative pressure channel 430, ensuring smooth airflow in the negative pressure channel 430, and ensuring the reliability of the dirt being recycled to the dirt recycling unit of the cleaning device.

[0045] like Figure 2 As shown, in some embodiments, the cleaning head 10 includes a scraper 200, which supports the cleaning member 100, providing support when the cleaning member 100 scrapes the surface to be cleaned. Simultaneously, the scraper 200 also performs a cleaning function by scraping the surface, thus adding an extra scraping step and improving the cleaning effect. By increasing the thickness of the first positioning protrusion 121 along the fluid flow direction, a gap is created between the cleaning member 100 and the scraper 200. This gap forms an extension channel 130 of the negative pressure channel 430. This extension channel 130 effectively concentrates dirt from the surface to be cleaned into a smaller area, facilitating subsequent removal via the negative pressure channel 430.

[0046] See Figure 1 and Figure 3As shown, in some embodiments, the first positioning protrusion 121 includes a first connecting section 1211 and a first abutting section 1212 distributed along the fluid flow direction within the negative pressure channel 430. The first abutting section 1212 can abut against the side of the negative pressure unit 300 facing the cleaning body 110; a portion of the first connecting section 1211 is used for detachable connection with the negative pressure unit 300 to firmly fix the cleaning component 100 onto the cleaning head 10. It is understood that the detachable connection method includes, but is not limited to, threaded connection, pin connection, key connection, and plug-in connection. For example, in some embodiments, the negative pressure unit 300 is provided with a first mating part 310, which can be a first positioning groove 311. The first connecting section 1211 can be plugged into the first positioning groove 311. Through the plugging and mating of the first connecting section 1211 and the first positioning groove 311, the cleaning component 100 is detachably connected to the negative pressure unit 300.

[0047] See Figure 1 As shown, in some embodiments, the dimension of the first abutting segment 1212 along the second direction is larger than the dimension of the first connecting segment 1211 along the second direction. The second direction is perpendicular to the first direction and intersects the fluid flow direction within the negative pressure channel 430. Figure 1 As shown, the second direction is illustrated. In a practical application scenario, the second direction can be the length direction of the cleaning component 100. The first abutting section 1212 and the first connecting section 1211 make the shape of the first positioning protrusion 121 T-shaped. The first abutting section 1212 forms the straight part of the T-shape, and the first connecting section 1211 forms the I-shaped part of the T-shape. The straight part of the T-shape abuts against the negative pressure unit 300, and the I-shaped part of the T-shape is detachably connected to the negative pressure unit 300. At the same time, by setting the dimension of the first abutting section 1212 along the second direction to be larger than the dimension of the first connecting section 1211 along the second direction, the cross-sectional area of ​​the extended channel 130 formed between the cleaning component 100 and the scraping component 200 can be guaranteed, ensuring the suction effect.

[0048] In some other embodiments, a portion of the first abutting segment 1212 may abut against the negative pressure unit 300, and another portion of the first abutting segment 1212 may be detachably connected to the negative pressure unit 300. That is, the shape of the first abutting segment 1212 may be T-shaped, and the I-shaped portion of the first abutting segment 1212 and the first connecting segment 1211 may be detachably connected to the negative pressure unit 300.

[0049] like Figure 1As shown, in some embodiments, there are multiple first positioning portions 120, which are spaced apart along the second direction; the first negative pressure port 111 is located between two adjacent first positioning portions 120. By providing multiple first positioning portions 120, the contact area between the cleaning component 100 and the negative pressure unit 300 is increased, thereby improving the connection effect between the two, thus improving the firmness of the connection between the cleaning component 100 and the cleaning head 10, reducing the risk of accidental loosening or falling off, and improving the reliability of the cleaning head 10 in use.

[0050] See Figure 1 and Figure 3 As shown, in some embodiments, a first stop portion 112 is constructed at one end of the cleaning body 110 near the first negative pressure port 111 along the fluid flow direction within the negative pressure channel 430. The first stop portion 112 includes a first portion 1121 and a second portion 1122 distributed along the fluid flow direction within the negative pressure channel 430; the first portion 1121 increases in size along the first direction along the fluid flow direction within the negative pressure channel 430; the second portion 1122 is used to abut against the negative pressure unit 300 to close a portion of the opening of the extension channel 130.

[0051] For example in Figure 3 In the view shown, a first stop portion 112 is provided at the lower end of the cleaning body 110, and the first stop portion 112 is provided on both the left and right sides of the cleaning body 110. The first stop portion 112 extends along the first direction, so that when the cleaning component 100 is connected to the negative pressure unit 300, the first stop portion 112 can wrap around the edge of the negative pressure unit 300, thereby closing the openings of the negative pressure channel 430 distributed along the second direction. Since the openings are not directly facing the surface being cleaned, the first stop portion 112 helps to limit the spread of dirt and reduces the risk of leakage of the cleaning head 10.

[0052] In some embodiments, the cleaning component 100 includes a scraper and a spatula, which can clean hard surfaces such as glass and countertops. During the cleaning process, it repeatedly comes into physical contact with dirt, thereby loosening the dirt. When the cleaning component 100, such as the scraper and spatula, has been used for a long time, the cleaning component 100 can be removed from the cleaning head 10, and only the scraper and spatula can be replaced. Alternatively, the cleaning head 10, which is connected to the cleaning component 100, can be replaced entirely from the cleaning equipment, thereby improving the convenience of replacement, increasing cleaning efficiency, and saving replacement costs.

[0053] See Figures 2 to 4As shown, in a further embodiment of this application, a cleaning head 10 is also provided, including a negative pressure unit 300 and a cleaning component 100 as described in any of the above embodiments; the negative pressure unit 300 is configured with a first mating part 310, which engages with a first positioning part 120. Since the cleaning head 10 includes the aforementioned cleaning component 100, when the cleaning component 100 becomes soiled, the cleaning component 100 can be easily removed by disconnecting the first positioning part 120 from the first mating part 310, thereby enabling better cleaning of the cleaning component 100 and ensuring the subsequent cleaning effect of the cleaning head 10.

[0054] See Figures 1 to 4 As shown, in some embodiments, one of the first positioning portion 120 and the first mating portion 310 is constructed as a first positioning protrusion 121, and the other is constructed as a first positioning groove 311 for engaging with the first positioning protrusion 121. For example, in Figure 3 and Figure 4 In the illustrated embodiment, the first positioning portion 120 is configured as a first positioning protrusion 121, and the first mating portion 310 is configured as a first positioning groove 311, with the first positioning protrusion 121 and the first positioning groove 311 interlocking. It is understood that the positions of the first positioning protrusion 121 and the first positioning groove 311 can be interchanged; that is, in other embodiments, the first mating portion 310 is configured as the first positioning protrusion 121, and the first positioning portion 120 is configured as the first positioning groove 311 for interlocking with the first positioning protrusion 121.

[0055] See Figures 3 to 4 As shown, in one embodiment, one of the cleaning component 100 and the negative pressure unit 300 is provided with a second positioning portion 360, and the other is provided with a second mating portion 140 for engaging with the second positioning portion 360. The engagement of the second positioning portion 360 and the second mating portion 140 further improves the connection reliability between the cleaning component 100 and the negative pressure unit 300, thereby reducing the possibility of the cleaning component 100 becoming loose. In some embodiments, the second positioning portion 360 is a second positioning protrusion 361, and the second mating portion 140 is a second positioning groove 520. Of course, the positions of the second positioning protrusion 361 and the second positioning groove 520 can also be interchanged.

[0056] See Figures 3 to 4 As shown, in some embodiments, the negative pressure unit 300 includes a first negative pressure component 301 and a second negative pressure component 400; the first negative pressure component 301 and the second negative pressure component 400 cooperate to form a negative pressure channel 430; a first mating part 310 is disposed on the first negative pressure component 301. The separate design of the first negative pressure component 301 and the second negative pressure component 400 facilitates disassembly and cleaning of the negative pressure unit 300, making maintenance and cleaning easier.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments, the first positioning part 120 is configured as a first positioning protrusion 121, and the first mating part 310 is configured as a first positioning groove 311; the second negative pressure member 400 has a first abutting protrusion 411 on the side facing the first negative pressure member 301, and the first abutting protrusion 411 is used to abut against the first positioning protrusion 121 passing through the first positioning groove 311 at least under negative pressure. By abutting against the first positioning protrusion 121 passing through the first positioning groove 311, the cleaning member 100 is further fixed, the connection area between the cleaning member 100 and the negative pressure unit 300 is increased, and the fixing effect of the cleaning member 100 is improved. In some embodiments, along the fluid flow direction of the negative pressure channel 430, the thickness of the lower end of the first abutting protrusion 411 is less than the thickness of the upper end.

[0058] See Figure 4 As shown, in some embodiments, at least one of the first negative pressure member 301 and the second negative pressure member 400 has an abutment rib 320 on its side facing the other, and the abutment rib 320 abuts against the other. For example, in Figure 4 In the illustrated embodiment, the surface of the first negative pressure component 301 facing the second negative pressure component 400 is provided with an abutment rib 320. On one hand, the abutment rib 320 can support the first negative pressure component 301 and the second negative pressure component 400, thereby enhancing the structural strength of the first negative pressure component 301 and the second negative pressure component 400. On the other hand, the first negative pressure component 301 abuts against the second negative pressure component 400 through the abutment rib 320, forming a certain gap between the first negative pressure component 301 and the second negative pressure component 400. This gap forms a negative pressure channel 430, thereby ensuring unobstructed airflow within the negative pressure channel 430. In other embodiments, the abutment rib 320 may also be provided on the surface of the second negative pressure component 400 facing the first negative pressure component 301.

[0059] See Figure 4As shown, in some embodiments, a first marking portion 351 is provided at the end of the negative pressure unit 300 away from the first negative pressure port 111. For example, in the embodiment shown in the figure, the first marking portion 351 is connected to the end of the first negative pressure member 301 away from the first negative pressure port 111. The first marking portion 351 stores the type information of the cleaning head 10. When the cleaning head 10 is connected to the handle of the cleaning device, the handle can recognize the first marking portion 351. For example, the handle is equipped with an identification portion to recognize the first marking portion 351 and transmit the signal to the control unit of the cleaning device. The control unit can identify the type information of the cleaning head 10 according to the signal, and then adjust the working mode of the cleaning device according to the type information, such as adjusting the suction force or suction power, to match the actual usage scenario. In one embodiment, the marking portion can be a QR code, NFC, RFID, or Bluetooth, and the identification portion can be a reader or receiver. In other embodiments, the first marking portion and the identification portion can be pins. When the cleaning head is connected to the handle, the marking pin of the cleaning head and the identification pin of the handle are connected to realize signal transmission.

[0060] See Figure 4 As shown, in some embodiments, a first mounting bracket 352 is provided at the end of the first negative pressure member 301 away from the first negative pressure port 111, and a first marking portion 351 is detachably connected to the first mounting bracket 352. In some embodiments, one of the first marking portion 351 and the first mounting bracket 352 is provided with a connecting pin, and the other is provided with a connecting hole for insertion of the connecting pin. For example, in the embodiment shown in the figure, the first mounting bracket 352 is provided with a connecting pin, and the first marking portion 351 is provided with a connecting hole. Of course, the positions of the connecting pin and the connecting hole can also be interchanged.

[0061] See Figures 3 to 4 As shown, in some embodiments, one of the first negative pressure member 301 and the second negative pressure member 400 is provided with a first sealing ridge 330, and the other is provided with a first sealing groove 420 for engaging with the first sealing ridge 330. For example, in the embodiment shown in the figures, the first negative pressure member 301 is provided with the first sealing ridge 330, and the second negative pressure member 400 is provided with the first sealing groove 420. Through the engaging cooperation between the first sealing ridge 330 and the first sealing groove 420, the sealing effect between the first negative pressure member 301 and the second negative pressure member 400 is improved, reducing the risk of dirt leakage, while ensuring the suction power within the negative pressure channel 430. In other embodiments, the first negative pressure member 301 may be provided with the first sealing groove 420, and the second negative pressure member 400 may be provided with the first sealing ridge 330. By improving the sealing performance of the negative pressure unit 300, the first marking portion 351 can be protected from dirt corrosion.

[0062] In some embodiments, a first sealing element is connected between the first sealing ridge 330 and the first sealing groove 420. That is, the first sealing element is accommodated within the first sealing groove 420, and the first sealing ridge 330 is pressed against the first sealing element. By providing the first sealing element, the sealing effect between the first negative pressure element 301 and the second negative pressure element 400 is further improved, reducing the risk of leakage and improving waterproof performance. In some embodiments, the first sealing element can be a sealing ring, and the shape of the sealing ring can be adapted to the shape of the first sealing ridge 330. For example, in the embodiment shown in the accompanying drawings, the shapes of the first sealing ridge 330 and the first sealing groove 420 are U-shaped.

[0063] See Figures 3 to 4 As shown, in some embodiments, a negative pressure connection interface 340 is provided at the end of the negative pressure unit 300 away from the first negative pressure port 111, and the negative pressure connection interface 340 communicates with the negative pressure channel 430. When the cleaning head 10 is connected to the handle of the cleaning device, the negative pressure connection interface 340 can dock with the suction channel of the handle, realizing the communication between the suction channel and the negative pressure channel 430. In the embodiment shown in the figure, the negative pressure connection interface 340 can be rectangular. In other embodiments, the negative pressure connection interface 340 can also be circular, etc., and there is no specific limitation.

[0064] See Figures 2 to 4 As shown, in some embodiments, the cleaning head 10 includes a spraying unit 500, the cleaning source sprayed by the spraying unit 500 being able to cover at least a portion of the cleaning component 100. With this configuration, the cleaning source sprayed from the spraying unit 500 can wash away some of the dirt adhering to the cleaning component 100, thus achieving partial self-cleaning of the cleaning component 100 and extending the cleaning time of the cleaning head 10 per cycle to some extent. In some embodiments, the spraying unit 500 is connected to the side of the cleaning component 100 away from the negative pressure unit 300, and the spraying unit 500 is provided with a nozzle 510 for spraying the cleaning source, the spraying direction of the nozzle 510 intersecting with the cleaning component 100. With this configuration, the spraying unit 500 can directly spray part of the cleaning source onto the cleaning component 100 through the nozzle 510, achieving self-cleaning of the cleaning component 100.

[0065] See Figures 3 to 4As shown, one of the spray unit 500, cleaning component 100, and negative pressure unit 300 is equipped with a second positioning protrusion 361, while the other two are equipped with second positioning grooves 520 for engaging with the second positioning protrusion 361. For example, in the embodiment shown in the attached figure, the first negative pressure component 301 of the negative pressure unit 300 is equipped with the second positioning protrusion 361, and the cleaning component 100 and spray unit 500 are provided with second positioning grooves 520 at corresponding positions. The second positioning protrusion 361 passes through the second positioning grooves 520 of the cleaning component 100 and the spray unit 500 in sequence, thereby connecting and fixing the three components. Furthermore, the second positioning protrusion 361 is provided with a screw hole. After the second positioning protrusion 361 passes through the second positioning grooves 520 of the cleaning component 100 and the spray unit 500, it can be further connected to the threaded hole of the second positioning protrusion 361 by a screw thread, further improving the connection effect of the three components.

[0066] See Figures 3 to 4 As shown, in some embodiments, the cleaning head 10 includes a first housing 600 and a second housing 700 connected to the first housing 600. The second housing 700 cooperates with the first housing 600 to form a first receiving cavity 701, which is used to accommodate a portion of the cleaning component 100, the negative pressure unit 300, and the spraying unit 500. The first housing 600 and the second housing 700 effectively prevent damage to the negative pressure unit 300 and the spraying unit 500 caused by impacts or friction from hard objects in the external environment, improving waterproof and dustproof performance and extending the service life of the cleaning head 10. Simultaneously, when the cleaning source sprayed by the spraying unit 500 is high-temperature steam, the arrangement of the first housing 600 and the second housing 700 reduces the possibility of the user being scalded by high-temperature steam.

[0067] See Figures 3 to 4 As shown, in some embodiments, a first connecting portion 710 is provided at the end of the second housing 700 away from the first negative pressure port 111. The first connecting portion 710 is used for detachable connection with the handle of the cleaning device. In some embodiments, the first connecting portion 710 is configured with a second receiving cavity 711, in which the negative pressure connection interface 340 of the negative pressure unit 300 and the aforementioned first marking portion 351 are located. Simultaneously, the second housing 700 can be sleeved onto the handle of the cleaning device through the second receiving cavity 711, enabling the cleaning head 10 to connect with the handle.

[0068] See Figures 3 to 4 As shown, in some embodiments, at least one of the first housing 600 and the second housing 700 has reinforcing ribs on its inner surface. The inner surface is the side facing each other. For example, in the embodiment shown in the figures, both the first housing 600 and the second housing 700 have reinforcing ribs to improve the overall structural strength of the cleaning head 10 and extend its service life.

[0069] See Figures 3 to 4 As shown, in some embodiments, one of the first housing 600, the negative pressure unit 300, and the second housing 700 is provided with a third positioning protrusion 731, while the other two are provided with third positioning grooves 610 for engaging with the third positioning protrusion 731. For example, in the embodiment shown in the figures, the second housing 700 is provided with a third positioning protrusion 731, and the corresponding positions of the negative pressure unit 300 and the first housing 600 are provided with third positioning grooves 610. The third positioning protrusion 731 passes through the third positioning grooves 610 of the negative pressure unit 300 and the first housing 600 in sequence, thereby connecting and fixing the first housing 600, the negative pressure unit 300, and the second housing 700 together. Furthermore, the third positioning protrusion 731 may be provided with screw holes. After the third positioning protrusion 731 passes through the third positioning grooves 610 of the negative pressure unit 300 and the first housing 600, it can be further connected to the threaded hole of the third positioning protrusion 731 by screws, further improving the connection effect between the components. In other embodiments, the first housing 600 may be provided with a third positioning protrusion 731, and the negative pressure unit 300 and the second housing 700 may be provided with a third positioning groove 610. In another embodiment, the negative pressure unit 300 may be provided with a third positioning protrusion 731, and the first housing 600 and the second housing 700 may be provided with a third positioning groove 610.

[0070] See Figures 2 to 4 As shown, in some embodiments, the cleaning head 10 further includes a scraper 200; the scraper 200 and the cleaning member 100 are respectively located on both sides of the negative pressure unit 300 along the first direction. The scraper 200 provides support for the cleaning member 100 when scraping the surface to be cleaned, and also has a cleaning effect on the surface. In addition, the scraper 200 can form a sealing edge with the inlet edge of the negative pressure channel 430 of the second negative pressure member 400 in the second direction, thereby preventing fluid or dirt in the negative pressure channel 430 from entering the aforementioned first receiving cavity 701, reducing the risk of dirt leakage, and ensuring the suction power within the negative pressure channel 430.

[0071] like Figure 2As shown, in some embodiments, the cleaning component 100 and the scraping component 200 are arranged at a preset angle. The scraping component 200 cooperates with the cleaning component 100 to form an extension channel 130. In this way, dirt can sequentially pass through the first negative pressure port 111 and the extension channel 130 into the negative pressure channel 430. By collecting the dirt from the first negative pressure port 111 into the extension channel 130, it is easier to remove it subsequently through the negative pressure channel 430. Moreover, the dirt has a longer path when passing through the extension channel 130, which increases the contact time between the dirt and the airflow and increases the probability of the dirt being carried away. In some embodiments, a certain gap can be maintained between the cleaning component 100 and the scraping component 200 to ensure smooth airflow within the extension channel 130.

[0072] In some embodiments, both the cleaning element 100 and the scraping element 200 can be scrapers, that is, the cleaning head 10 is configured as a dual-scraper type, wherein one of the cleaning element 100 and the scraping element 200 can be a hard scraper and the other a flexible scraper. For example, the cleaning element 100 is a flexible scraper made of high-temperature resistant rubber, and the scraping element 200 is a hard scraper. Of course, in other embodiments, it can also be configured as a single scraper, that is, without the scraping element 200, depending on the actual usage requirements.

[0073] See Figures 3 to 4 As shown, in some embodiments, the scraper 200 can be connected to the aforementioned second housing 700. One of the scraper 200 and the second housing 700 has a first limiting protrusion 210, and the other has a first limiting groove 721 for engaging with the first limiting protrusion 210. For example, in the embodiment shown in the figures, the scraper 200 has the first limiting protrusion 210, and the second housing 700 has the first limiting groove 721 for engaging the first limiting protrusion 210. The shapes of the first limiting protrusion 210 and the first limiting groove 721 are adapted, for example, the cross-section of the first limiting protrusion 210 is circular. In this way, the scraper 200 can be securely connected to the cleaning head 10, allowing the scraper 200 to support the cleaning member 100 and to scrape the surface to be cleaned.

[0074] On the other hand, one embodiment of this application also provides a cleaning device, including a cleaning source supply unit (not shown), a dirt collection unit (not shown), and a cleaning head 10 as described in any of the above embodiments. The cleaning source supply unit provides a cleaning source to the surface to be cleaned through the cleaning head 10, thereby cleaning the stains on the surface to be cleaned. The negative pressure unit 300 can be connected to the dirt collection unit. The cleaned dirt enters the negative pressure channel 430 through the first negative pressure port 111 under the action of negative pressure suction, so as to absorb the cleaned dirt.

[0075] In one embodiment, the cleaning source includes at least one of water vapor, water, and a solution containing a cleaning agent, which can be selected by those skilled in the art according to actual needs. When water vapor is used as the cleaning source, the high temperature of the water vapor during direct spraying can accelerate the dissolution of stains, further improving the cleaning effect. When water or a solution containing a cleaning agent is used as the cleaning source, the spray pressure can be increased, improving the spray force, which is more effective for cleaning larger volumes of dirt.

[0076] 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 spraying unit via a pipeline. The water pump is electrically connected to a controller, which controls the pump to deliver the cleaning source from the clean water tank to the spraying unit via the pipeline, and then sprays the cleaning source onto the surface to be cleaned through the nozzle of the spraying unit. In some embodiments, a liquid sensor for detecting liquid is provided on the pipeline connecting the clean water tank and the water pump. The liquid sensor is electrically connected to the controller, which controls the operation of the spraying unit based on the liquid detected by the liquid sensor.

[0077] 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 unit. 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 surface of the object to be cleaned into the wastewater tank through a first negative pressure port. In one embodiment, the negative pressure suction device can be a vacuum pump. In some embodiments, the wastewater tank is equipped with a level sensor for detecting the liquid level inside the tank. The level sensor is electrically connected to the controller, which can control the operation of the waste collection unit based on the liquid level detected by the level sensor.

[0078] In some embodiments, a steam generator (not shown) is provided between the water pump and the spraying unit. The steam generator converts the clean water pumped in by the water pump into high-temperature, high-pressure steam, which is then sprayed onto the surface to be cleaned through the spraying unit. In one embodiment, the steam generator can be a heater.

[0079] 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.

[0080] The above embodiments merely illustrate 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.
