Description

Technical Field

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

[0002] With the rapid development of technology, intelligent products are gradually entering users' lives. For example, they can automatically or semi-automatically clean surfaces such as floors, desktops, and walls, with high cleaning efficiency and good cleaning effect.

[0003] In some cleaning equipment, high-temperature steam is typically generated and sprayed onto the cleaning surface to melt stubborn stains, thereby improving cleaning efficiency and effectiveness. However, the structural design of traditional cleaning equipment limits the improvement in cleaning effect and affects the user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide a cleaning mechanism, steam cleaning device, and cleaning equipment to effectively improve the cleaning effect.

[0005] A cleaning mechanism is provided for installation on the main unit of a cleaning device. The cleaning mechanism includes: a steam output member having a steam output port; and a scraping member disposed on the steam output member, including a scraping portion for contacting the surface to be cleaned, the scraping portion being configured to be located in front of the steam output port in the forward direction of the main unit.

[0006] The aforementioned cleaning mechanism incorporates a steam output component and a scraper. During the cleaning process, steam is output from the steam outlet of the steam output component to dissolve dirt on the surface to be cleaned; simultaneously, the scraper removes the dirt or dissolved dirt from the surface, thus enhancing the cleaning capability of the equipment. Because the scraping part of the scraper is located in front of the steam outlet, it can achieve edge cleaning, effectively improving the problem of cleaning equipment struggling to clean corners and reducing the likelihood of blind spots during cleaning, further enhancing the cleaning effect and improving the user experience.

[0007] In some embodiments, the scraper further includes a fixing part connected to the scraper, and the fixing part is disposed on the surface of the steam output member opposite to the steam output port.

[0008] Therefore, by fixing the scraping part to the steam output component, the scraping part is stably fixed in front of the steam output port, so as to achieve effective and stable edge cleaning and improve the cleaning effect.

[0009] In some embodiments, the surface of the steam output component includes a mounting surface and a front end surface. The mounting surface faces away from the steam output port, the front end surface is located at the front end of the steam output component in the forward direction of the main unit, the fixing part is provided on the mounting surface, the scraping part is located on one side of the front end surface, and the scraping part extends beyond the end of the front end surface away from the mounting surface.

[0010] Therefore, by extending the scraping part beyond one end of the front face, the steam outlet can maintain a certain distance from the surface to be cleaned when the scraping part comes into contact with it, facilitating the output of steam to the dirt. At the same time, when the scraping part comes into contact with the surface to be cleaned, a relatively sealed environment can be formed inside the scraping part, reducing the chance of steam escaping and helping to maintain the temperature of the steam, thereby further improving the dirt dissolution effect and thus enhancing the cleaning effect.

[0011] In some embodiments, the cleaning mechanism further includes an air supply component disposed on the steam output component and communicating with the steam output port. The fixing part is provided with a perforation, through which the air supply component passes and is used to connect with the steam generator.

[0012] Therefore, it can be seen that the introduction of the gas supply component facilitates the introduction of steam into the steam output component located on one side of the fixed part, so as to achieve steam cleaning.

[0013] In some embodiments, the steam output component has a gas distribution chamber, and the gas delivery component is connected to the steam output port through the gas distribution chamber.

[0014] Therefore, it can be seen that by using the gas distribution chamber, the steam in the gas delivery component is effectively diverted to the steam output port, thus achieving stable steam cleaning.

[0015] In some embodiments, the cleaning mechanism further includes a connector, to which both the steam output component and the fixing part are connected, and the steam output component is located on the side of the fixing part facing away from the connector.

[0016] Therefore, it can be seen that the fixing part and the steam output part can be stably connected through the connecting body.

[0017] In some embodiments, the connector is provided with a first snap-fit ​​portion, the fixing portion is provided with a receiving hole, and the steam output component is provided with a second snap-fit ​​portion. The first snap-fit ​​portion passes through the receiving hole and engages with the second snap-fit ​​portion.

[0018] Therefore, during structural assembly, the first snap-fit ​​part can be passed through the receiving hole, so that the first snap-fit ​​part and the second snap-fit ​​part can be snapped together. This allows the connecting body, the fixing part and the steam output part to be effectively combined, which not only ensures structural stability, but also facilitates the assembly between structures.

[0019] In some embodiments, the connecting body is provided with a positioning protrusion, the fixing part is provided with a first positioning hole, and the steam output part is provided with a second positioning hole, with the positioning protrusion passing through the first positioning hole and the second positioning hole in sequence.

[0020] Therefore, during the assembly of the connector, fixing part, and steam output component, the positioning protrusions on the connector can sequentially pass into the first positioning hole and the second positioning hole, allowing the three components to be quickly and effectively positioned, thus facilitating a stable and rapid connection. Simultaneously, the engagement of the positioning protrusions with the first and second positioning holes respectively enhances the stability of the connection between the connector, fixing part, and steam output component.

[0021] In some embodiments, the connector is provided with a fixing member, the fixing member is provided with a first fixing hole, the fixing part is provided with a through hole, the steam output part is provided with a second fixing hole, the fixing member passes through the through hole, and the first fixing hole and the second fixing hole are arranged opposite to each other.

[0022] Therefore, during assembly, at least a portion of the fastener can be inserted into the through hole, aligning the first fixing hole and the second fixing hole on the fastener. This allows the operator to sequentially insert the fastener into the second fixing hole and the first fixing hole, achieving a quick and stable connection.

[0023] A steam cleaning device includes: a main housing configured to be located at the front end of the main unit in the forward direction of the main unit; and a cleaning mechanism, as described in any of the above, wherein the cleaning mechanism is at least partially disposed in the main housing.

[0024] The aforementioned steam cleaning device employs the cleaning mechanism described above, incorporating a steam output component and a scraper. During the cleaning process, steam is output from the steam outlet of the steam output component to dissolve dirt on the surface to be cleaned; simultaneously, the scraper removes the dirt or dissolved dirt from the surface, thus enhancing the cleaning capability of the equipment. Because the scraping part of the scraper is located in front of the steam outlet, it can achieve edge cleaning, effectively improving the problem of cleaning equipment struggling to clean corners and reducing the likelihood of blind spots during cleaning, further enhancing the cleaning effect and improving the user experience.

[0025] In some embodiments, the steam cleaning device further includes a drive unit and a transmission assembly disposed within the main housing. The drive unit is connected to the steam output unit and / or the scraper unit via the transmission assembly, and is used to drive the steam output unit and the scraper unit to switch between a clearance position away from the surface to be cleaned and a cleaning position close to the surface to be cleaned.

[0026] Therefore, during the cleaning process, the drive unit can actuate the transmission assembly, causing the steam output component and the scraper to move to the cleaning position. At this time, the steam output component outputs steam to the surface to be cleaned, and the scraper removes dirt or moisture from the surface by contact. After cleaning is completed, the drive unit can actuate the transmission assembly, causing the steam output component and the scraper to move to a clearance position, facilitating the smooth passage of the main unit or overcoming obstacles.

[0027] A cleaning device includes a main unit and above steam cleaning devices. The main unit includes a roller brush. A main housing covers the roller brush, and a scraping part is located on the side of the steam outlet facing away from the roller brush in the forward direction of the main unit.

[0028] The aforementioned cleaning equipment employs the cleaning mechanism described above, incorporating a steam output component and a scraper. During the cleaning process, steam is output from the steam outlet of the steam output component to dissolve dirt on the surface. Simultaneously, the scraper removes the dirt or dissolved dirt from the surface, thus enhancing the cleaning capability of the equipment. Because the scraping part of the scraper is located in front of the steam outlet, it can achieve edge cleaning, effectively addressing the difficulty of cleaning corners and reducing the likelihood of blind spots during cleaning, further improving cleaning results and enhancing the user experience.

[0047] In some embodiments, please refer to Figures 1 to 3This application provides a cleaning mechanism for installation on the main unit 60 of a cleaning device. The cleaning mechanism includes: a steam output member 10 with a steam output port 11 thereon; and a scraping member 20 disposed on the steam output member 10, which includes a scraping part 21 for contacting the surface 70 to be cleaned. The scraping part 21 is configured to be located in front of the steam output port 11 in the forward direction X of the main unit 60.

[0048] The aforementioned cleaning mechanism incorporates a steam output component 10 and a scraper component 20. During the cleaning process, steam is output from the steam output port 11 of the steam output component 10 to the surface 70 to be cleaned, dissolving the dirt on the surface 70. Simultaneously, the scraper component 20 scrapes away the dirt or dissolved dirt from the surface 70, thus enhancing the cleaning capability of the cleaning equipment. Since the scraping part 21 of the scraper component 20 is located in front of the steam output port 11, it can achieve edge cleaning, effectively improving the problem of cleaning equipment struggling to clean corners, reducing the likelihood of blind spots during cleaning, further enhancing the cleaning effect, and improving the user experience.

[0049] It should be noted that the steam output component 10 refers to a structure that can output steam to the surface 70 to be cleaned through the steam output port 11, and it can be connected to the steam generator on the cleaning equipment. During the cleaning process, the steam generator can input steam into the steam output component 10. The steam generator can be connected to the steam output component 10 through the delivery pipe 54.

[0050] The scraper 20 is mounted on the steam output component 10, so that when the steam output component 10 outputs steam to the surface 70 to be cleaned, or simultaneously, the scraper 20 can move with the main unit 60 to scrape away dirt on the surface 70 to be cleaned. Since the scraper part 21 is located in front of the steam output port 11, it can better reach the space in front of the surface 70 while still providing steam output, reducing the chance of the steam output component 10 obstructing the scraper part 21. This allows the scraper part 21 to reach into corners or under obstacles more frequently during cleaning, achieving thorough cleaning and reducing the chance of cleaning dead spots.

[0051] The scraper 20 can be installed in various positions on the steam output component 10, such as at the top, bottom, or side of the steam output component 10, as long as the scraper 21 is located in front of the steam output port 11. When the scraper 21 is located in front of the steam output port 11, it can guide and protect the steam output port 11, ensuring that the output steam is accurately applied to the surface 70 to be cleaned; it can also prevent steam from spreading forward, reducing the risk of high-temperature damage to animals or people in front.

[0052] Meanwhile, the scraper 20 can be fixed to the steam output component 10 in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, bonding, etc.; or, the two can be an integrated structure, such as, integrally formed by injection molding, die casting, extrusion, etc.

[0053] Furthermore, the steam output component 10 and the scraper component 20 can be controlled to move relative to the main unit 60, allowing them to switch between a clearance position away from the surface to be cleaned 70 and a cleaning position close to the surface to be cleaned 70. Thus, during the cleaning process, the steam output component 10 and the scraper component 20 can be controlled to move together and approach the surface to be cleaned 70; after cleaning is completed, the steam output component 10 and the scraper component 20 can be controlled to move away from the surface to be cleaned 70.

[0054] It should also be noted that, in the forward direction X of the main unit 60, the scraping part 21 being located in front of the steam outlet 11 should be understood as follows: during the forward movement of the main unit 60, the scraping part 21 can reach any position on the surface 70 to be cleaned before the steam outlet 11. For ease of understanding, taking a handheld cleaning device as an example, the main unit 60 is equipped with a roller brush 61, and in the forward direction X of the main unit 60, the scraping part 21 is located on the side of the steam outlet 11 away from the roller brush 61.

[0055] Further, please refer to Figure 4 and Figure 5 The scraping component 20 also includes a fixing part 22, with the scraping part 21 connected to the fixing part 22. The fixing part 22 is provided on the surface of the steam output component 10 facing away from the steam output port 11. Therefore, the fixing part 22 stably fixes the scraping part 21 to the steam output component 10, thereby stabilizing the scraping part 21 in front of the steam output port 11, achieving effective and stable edge cleaning and improving the cleaning effect.

[0056] It should be noted that when the fixing part 22 is disposed on the surface of the steam output component 10 facing away from the steam output port 11, the scraping part 21 can extend from top to bottom to the front of the steam output port 11. The fixing part 22 can be installed on the steam output component 10 in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, and bonding. Similarly, the connection between the fixing part 22 and the connecting part can also be made in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, and bonding. Of course, the fixing part 22 and the connecting part can also be designed as an integrated structure, which can reduce the connection stress between them and improve the strength of the structure.

[0057] In some embodiments, please refer to Figure 5The surface of the steam output component 10 includes a mounting surface 15 and a front end surface 16. The mounting surface 15 faces away from the steam output port 11, and the front end surface 16 is located at the front end of the steam output component 10 in the forward direction X of the main unit 60. The fixing part 22 is provided on the mounting surface 15, and the scraping part 21 is located on one side of the front end surface 16, extending beyond the end of the front end surface 16 away from the mounting surface 15. Therefore, by extending the scraping part 21 beyond the end of the front end surface 16, the steam output port 11 can maintain a certain distance from the surface 70 to be cleaned when the scraping part 21 contacts it, facilitating the output of steam from the steam output port 11 to the dirt. Simultaneously, when the scraping part 21 contacts the surface 70 to be cleaned, a relatively sealed environment can be formed inside the scraping part 21, reducing the probability of steam leakage and helping to maintain the steam temperature, thereby further improving the dirt dissolution effect and thus enhancing the cleaning effect.

[0058] It should be noted that the front end face 16 refers to one side of the steam output component 10 along the forward direction X of the main unit 60. For example, when the main unit 60 includes a roller brush 61, the front end face 16 can be the side of the steam output component 10 facing away from the roller brush 61 along the forward direction X of the main unit 60. In this embodiment, the scraping part 21 can be attached to the front end face 16, or a certain gap can be maintained between it and the front end face 16.

[0059] Meanwhile, the front end face 16 and the mounting face 15 can be designed as a smooth transition surface, which can avoid wear on the scraper 20 at the connection between the front end face 16 and the mounting face 15 and ensure structural stability. In addition, an arc-shaped connecting part 23 can also be provided between the fixing part 22 and the scraping part 21, so that the fixing part 22 and the scraping part 21 are smoothly connected.

[0060] Furthermore, when both the steam output component 10 and the scraper 20 can move in a controlled manner, their movement trajectories can be either straight lines or curved paths around the roller brush 61 of the main unit 60. When the steam output component 10 and the scraper 20 are configured to move along a curve around the roller brush 61 of the main unit 60, the fixing part 22 and the scraper part 21 can be set at an obtuse angle, so that after the curved movement, the scraper part 21 can contact the surface 70 to be cleaned in a vertical or near-vertical direction. Similarly, the mounting surface 15 and the front end surface 16 can also be set at an obtuse angle to better accommodate the installation of the scraper 20.

[0061] In some embodiments, please refer to Figures 6 to 8 The cleaning mechanism also includes a gas supply component 30, which is located on the steam output component 10 and communicates with the steam output port 11. A through-hole 27 is provided on the fixing part 22, through which the gas supply component 30 passes and is used to connect to the steam generating device. Therefore, the introduction of the gas supply component 30 facilitates the supply of steam to the steam output component 10 located on one side of the fixing part 22, thereby achieving steam cleaning.

[0062] It should be noted that a steam generator is a component capable of producing steam. The steam produced flows into the steam outlet 11 through the steam conveyor 30 and is discharged from the steam outlet 11. The steam generator can operate in various ways, such as heating via resistance wire or electric heating tube, or heating via electromagnetic induction.

[0063] The gas supply component 30 refers to the structure connecting the steam generator and the steam output component 10. It communicates with the steam generator through the through hole 27 and past the scraper 20. There are various ways to fix the gas supply component 30 to the steam output component 10, such as, but not limited to, bolt connection, snap-fit, welding, and bonding; of course, it can also be an integrated structure with the steam output component 10.

[0064] Meanwhile, there can be various ways to connect the gas supply component 30 and the steam output port 11. For example, a cavity or flow channel can be provided in the steam output component 10 to connect the gas supply component 30 and the steam output port 11.

[0065] In some embodiments, please refer to Figure 6 and Figure 7 The steam output component 10 has a gas distribution chamber 12, and the gas delivery component 30 is connected to the steam output port 11 through the gas distribution chamber 12. Thus, the gas distribution chamber 12 effectively diverts the steam in the gas delivery component 30 to the steam output port 11, achieving stable steam cleaning.

[0066] It should be noted that the number of steam outlets 11 can be one or more. When there are multiple steam outlets 11, each steam outlet 11 can be connected to the same gas distribution chamber 12.

[0067] Meanwhile, the structure of the steam output component 10 can be an integral structure or a combined structure. For example, the steam output component 10 may include a first component 13 and a second component 14. The second component 14 cooperates with the first component 13 and forms a gas distribution chamber 12 between the two. The steam output port 11 is provided on the second component 14, and the fixing part 22 is provided on the surface of the first component 13 facing away from the second component 14.

[0068] The first component 13 and the second component 14 can be connected by, but are not limited to, bolt connection, snap-fit, or adhesive.

[0069] In some embodiments, please refer to Figure 1 The cleaning mechanism also includes a connector 40, to which both the steam output component 10 and the fixing part 22 are connected, with the steam output component 10 located on the side of the fixing part 22 facing away from the connector 40. Therefore, the connector 40 can stably connect the fixing part 22 and the steam output component 10.

[0070] It should be noted that when the steam output component 10 and the scraper component 20 can be moved in a controlled manner to switch between a clearance position away from the surface to be cleaned 70 and a cleaning position close to the surface to be cleaned 70, the drive connector 40 can be moved to indirectly drive the steam output component 10 and the scraper component 20.

[0071] Meanwhile, the connection method between the steam output component 10 and the fixing part 22 on the connector 40 can be various, such as, but not limited to, bolt connection, snap-fit, riveting, welding, pin connection, adhesive connection, etc.

[0072] Additionally, when the cleaning mechanism also includes an air supply component 30, a limiting groove 45 can be provided on the connecting body 40. The air supply component 30 passes through the through hole 27 on the fixing part 22 and can be inserted into the limiting groove 45 on the connecting body 40. At the same time, the limiting groove 45 can engage with the conveying pipe 54, so that the conveying pipe 54 is connected to the air supply component 30. It is easy to understand that if the steam output component 10 and the scraper 20 can be moved in a controlled manner, the air supply component 30 can disengage from the limiting groove 45 when the steam output component 10 and the scraper 20 move to the cleaning position; and the air supply component 30 can be inserted into the limiting groove 45 when the steam output component 10 and the scraper 20 move to the avoidance position. Here, the cleaning position refers to the position where the steam output component 10 and the scraper 20 are relatively closer to the surface to be cleaned 70, and the cleaning operation can be performed on the surface to be cleaned 70. The avoidance position refers to the position where the steam output component 10 and the scraper 20 are relatively farther away from the surface to be cleaned 70.

[0073] Further, please refer to Figure 1 , Figure 7 and Figure 8 The connector 40 has a first snap-fit ​​part 41, the fixing part 22 has a through-hole 24, and the steam output part 10 has a second snap-fit ​​part 17. The first snap-fit ​​part 41 passes through the through-hole 24 and engages with the second snap-fit ​​part 17. Therefore, during structural assembly, the first snap-fit ​​part 41 can pass through the through-hole 24, allowing it to engage with the second snap-fit ​​part 17. This effectively combines the connector 40, the fixing part 22, and the steam output part 10, ensuring structural stability and facilitating assembly.

[0074] It should be noted that the structures of the first latching part 41 and the second latching part 17 can have various designs. For example, the first latching part 41 may include a latching plate and a snap-fit ​​groove on the surface of the latching plate, and the second latching part 17 may include a protrusion. When the latching plate passes through the receiving hole 24, the protrusion of the second latching part 17 can be inserted into the snap-fit ​​groove to achieve latching. Alternatively, the first latching part 41 may include a latching plate and a protrusion on the surface of the latching plate, and the second latching part 17 may include a snap-fit ​​groove. When the latching plate passes through the receiving hole 24, the protrusion on the latching plate can be inserted into the snap-fit ​​groove to achieve latching as well.

[0075] Meanwhile, the number of the first latching part 41 and the second latching part 17 can be one or more. In some examples, the number of the first latching part 41 and the second latching part 17 is multiple, and each second latching part 17 can be distributed at intervals along the length direction of the steam output member 10.

[0076] In some embodiments, please refer to Figure 1 The connector 40 has a positioning protrusion 42, the fixing part 22 has a first positioning hole 25, and the steam output component 10 has a second positioning hole 18. The positioning protrusion 42 passes through the first positioning hole 25 and the second positioning hole 18 in sequence. Therefore, when the connector 40, fixing part 22, and steam output component 10 are assembled, the positioning protrusion 42 on the connector 40 can pass through the first positioning hole 25 and the second positioning hole 18 in sequence, allowing the three components to be quickly and effectively positioned, thus facilitating a stable and rapid connection. Simultaneously, the engagement of the positioning protrusion 42 with the first positioning hole 25 and the second positioning hole 18 respectively improves the stability of the connection between the connector 40, fixing part 22, and steam output component 10.

[0077] The positioning protrusion 42 can be located in various positions on the connector 40, such as in the middle or at the end of the connector 40. Furthermore, there can be one or more positioning protrusions 42. In some examples, the positioning protrusion 42 can be located at at least one end of the connector 40 along its length.

[0078] In some embodiments, please refer to Figure 1 and Figure 5 The connector 40 is provided with a fixing member 43, which has a first fixing hole 44. The fixing part 22 has a through hole 26, and the steam output part 10 has a second fixing hole 19. The fixing member 43 passes through the through hole 26, and the first fixing hole 44 and the second fixing hole 19 are arranged opposite to each other. Therefore, during assembly, at least a part of the fixing member 43 can be inserted into the through hole 26, so that the first fixing hole 44 on the fixing member 43 is aligned with the second fixing hole 19. In this way, the operator can insert the fasteners into the second fixing hole 19 and the first fixing hole 44 in sequence to achieve a quick and stable connection.

[0079] The first fixing hole 44 and the second fixing hole 19 can be threaded holes or non-threaded holes. When both the first fixing hole 44 and the second fixing hole 19 are non-threaded holes, both the first fixing hole 44 and the second fixing hole 19 can be designed as through holes 26 with split threads, so that the fastener can be a bolt with a nut.

[0080] Meanwhile, the number of fasteners 43 and second fixing holes 19 can be one or more. When there are multiple fasteners 43 and second fixing holes 19, they can be configured one-to-one.

[0081] In some embodiments, please refer to Figure 4 and Figure 11 This application provides a steam cleaning device, which includes: a main housing 50 configured to be located at the front end of the main unit 60 in the forward direction X; and a cleaning mechanism, as described above, at least partially disposed in the main housing 50.

[0082] The aforementioned steam cleaning device employs the cleaning mechanism described above, introducing a steam output component 10 and a scraper component 20. During the cleaning process, steam is output through the steam outlet 11 of the steam output component 10 to the surface 70 to be cleaned, dissolving the dirt on the surface 70. Simultaneously, the scraper component 20 scrapes away the dirt or dissolved dirt from the surface 70, thus enhancing the cleaning capability of the equipment. Since the scraping part 21 of the scraper component 20 is located in front of the steam outlet 11, it can achieve edge cleaning, effectively improving the problem of cleaning equipment struggling to clean corners, reducing the likelihood of blind spots during cleaning, further enhancing the cleaning effect, and improving the user experience.

[0083] It should be noted that the front end of the main unit 60 can be understood as the head structure of the main unit 60 along the forward direction X. Taking a handheld sweeper as an example, the main unit 60 includes a roller brush 61, and the front end of the main unit 60 can also be understood as the end of the main unit 60 near the roller brush 61. In some examples, the main housing 50 covers the roller brush 61.

[0084] Simultaneously, the steam output component 10 and the scraper 20 can remain immovable relative to the main housing 50, in which case both the steam output component 10 and the scraper 20 are located outside the main housing 50. Alternatively, the steam output component 10 and the scraper 20 can also move relative to the main housing 50. During cleaning, the steam output component 10 and the scraper 20 move relative to the main housing 50 and approach the surface to be cleaned 70, at which point they are located outside the main housing 50. When cleaning is complete, the steam output component 10 and the scraper 20 can retract into the main housing 50. Of course, in some examples, the steam output component 10 and the scraper 20 are always located outside the main housing 50.

[0085] Furthermore, the steam output component 10 and the scraper component 20 can be directly connected to the main housing 50 or indirectly connected. For example, the cleaning mechanism may also include a connector 40, which is located inside the main housing 50 and connected to the steam output component 10 and the scraper component 20.

[0086] Further, please refer to Figure 11The steam cleaning device also includes a drive unit 51 and a transmission assembly 52 disposed within the main housing 50. The drive unit 51 is connected to the steam output unit 10 and / or the scraper 20 via the transmission assembly 52, and is used to drive the steam output unit 10 and the scraper 20 to switch between a clearance position away from the surface to be cleaned 70 and a cleaning position close to the surface to be cleaned 70. Therefore, during the cleaning process, the drive unit 51 can drive the transmission assembly 52 to move the steam output unit 10 and the scraper 20 to the cleaning position. At this time, the steam output unit 10 can output steam to the surface to be cleaned 70, and the scraper 20 scrapes away dirt or moisture from the surface of the surface to be cleaned 70 in a contact manner. After cleaning is completed, the drive unit 51 can drive the transmission assembly 52 to move the steam output unit 10 and the scraper 20 to the clearance position, facilitating the smooth passage or obstacle crossing of the main unit 60.

[0087] It should be noted that the driving component 51 refers to the component that provides power for the movement of the cleaning mechanism, which may be, but is not limited to, a motor, an electric cylinder, etc. The transmission assembly 52 refers to the structure that transmits the power of the driving component 51 to the steam output component 10 and / or the scraping component 20. Its structure can have various designs, such as: a crank-slider mechanism, a gear and rack structure, a transmission linkage structure, etc.

[0088] To facilitate the resetting of the steam output component 10 and the scraping component 20, the steam cleaning device may also include an elastic element 53, which is used to drive the transmission assembly 52 back to its initial position. The elastic element 53 may be, but is not limited to, a spring, a torsion spring, etc.

[0089] Furthermore, the movement of the steam output component 10 and the scraper component 20 can be linear or curved. To better accommodate the roller brush 61 on the main unit 60, the main housing 50 can also be designed with an arc-shaped curved structure, in which case the movement of the steam output component 10 and the scraper component 20 can also be curved. In some examples, the cleaning mechanism may also include a connecting body 40, to which both the steam output component 10 and the scraper component 20 are connected, and the connecting body 40 is rotatably connected to the transmission component 52. It can be seen that since the connection between the connecting body 40 and the transmission component 52 is rotatable, during the driving process, when the steam output component 10 and the scraper component 20 move along a curved path, the connecting body 40 can adaptively rotate and adjust, ensuring that the movement of the steam output component 10 and the scraper component 20 is more stable and smooth.

[0090] In some embodiments, please refer to Figure 9 and Figure 10 This application provides a cleaning device, which includes a main unit 60 or more of a steam cleaning device. The main unit 60 includes a roller brush 61; the main housing 50 covers the roller brush 61, and the scraping part 21 is located on the side of the steam outlet 11 facing away from the roller brush 61 in the forward direction X of the main unit 60.

[0091] The aforementioned cleaning equipment employs the cleaning mechanism described above, incorporating a steam output component 10 and a scraper component 20. During the cleaning process, steam is output from the steam output port 11 of the steam output component 10 to the surface 70 to be cleaned, dissolving the dirt on the surface 70. Simultaneously, the scraper component 20 scrapes away the dirt or dissolved dirt from the surface 70, thus enhancing the cleaning capability of the equipment. Because the scraping part 21 of the scraper component 20 is located in front of the steam output port 11, it can achieve edge cleaning, effectively improving the problem of cleaning corners and reducing the likelihood of blind spots during cleaning, further enhancing the cleaning effect and improving the user experience.

[0092] The main unit 60 includes a roller brush 61, and the main housing 50 of the steam cleaning device covers the roller brush 61. The scraping part 21 is located on the side of the steam outlet 11 facing away from the roller brush 61 in the forward direction X of the main unit 60. This means that the scraping part 21 is located in front of the steam outlet 11 in the forward direction X of the main unit 60, enabling edge cleaning and effectively improving the problem of cleaning equipment having difficulty cleaning corners, reducing the probability of dead corners during cleaning. It is easy to understand that the roller brush 61 refers to the working component on the main unit 60 that cleans the surface to be cleaned; it can have a roller-like structure and can rotate around its own axis.

[0093] 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.

[0094] 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.
