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 for installation on the main unit of a cleaning device, the cleaning mechanism comprising: a steam output component including a working surface having a steam output port on the working surface; and a scraping component including a scraping portion for contacting the surface to be cleaned, the scraping portion protruding from the working surface and 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, the working surface of the steam output component faces the surface to be cleaned, and steam is output through its steam outlet 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 on the working surface and 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 portion protruding from the scraping portion, and the working surface is provided with an assembly groove, the fixing portion being disposed in the assembly groove.

[0008] Therefore, by setting an assembly groove on the working surface, the scraper is embedded in the steam output component through the fixing part, which makes the scraper stable and reduces the risk of damage to the scraper during the cleaning process, thus ensuring the structural stability of the cleaning mechanism.

[0009] In some embodiments, the fixing part protrudes from the end face of the scraping part, and the end face of the scraping part includes an abutting surface, which is located on the side of the fixing part facing the steam outlet along the thickness direction of the scraping part, and the abutting surface abuts against the working surface.

[0010] Therefore, when the fixing part is embedded in the assembly groove, the contact surface of the scraping part can abut against the working surface located between the assembly groove and the steam outlet. In this way, during the cleaning process, the scraping part can be supported on the side of the assembly groove near the steam outlet, ensuring that the scraping part is stably supported and preventing the scraping part from bending towards the steam outlet side, which would affect the steam cleaning effect.

[0011] In some embodiments, the scraping portion includes a first surface disposed facing the steam outlet and configured to direct at least a portion of the steam ejected from the steam outlet to the surface to be cleaned.

[0012] Therefore, during the cleaning process, when the scraping part contacts the surface to be cleaned in front of the steam outlet, the first surface can block the steam outlet and divert at least part of the steam, so that the steam can better act on the surface to be cleaned and improve the dissolution effect of dirt.

[0013] In some embodiments, the distance between the first surface and the center line of the steam outlet is denoted as D1, and the distance D1 gradually increases from the end of the scraping portion near the steam outlet to the end of the scraping portion away from the steam outlet.

[0014] Therefore, the further away the first side is from the steam output component, the greater the distance between it and the center line of the steam output port. This prevents the scraping part from turning outward during the cleaning process, which would result in incomplete scraping. It also makes it easier for the scraping part to be in an outward-turned state during the cleaning process, thus improving the scraping effect.

[0015] In some embodiments, the scraping portion further includes a second surface, which is disposed away from the first surface along the thickness direction of the scraping portion. The distance between the first surface and the second surface is denoted as D2, and the distance D2 gradually decreases from the end of the scraping portion near the steam output member to the end of the scraping portion away from the steam output member.

[0016] Therefore, it can be seen that the end of the scraping part closer to the steam output component is thicker, and the end closer to the surface to be cleaned is thinner. This makes the connection between the scraping part and the steam output component more stable. At the same time, it also makes the end of the scraping part in contact with the surface to be cleaned softer, which is beneficial to improving the scraping effect.

[0017] In some embodiments, the height of the scraping portion protruding from the working surface is denoted as H, where 5mm ≤ H ≤ 10mm.

[0018] Therefore, the height H of the scraping part can be between 5mm and 10mm, so that there is a certain contact force between the scraping part and the surface to be cleaned, which is conducive to improving the scraping ability of the scraping part and improving the cleaning effect; at the same time, it can also maintain a reasonable distance between the steam outlet and the surface to be cleaned, so that the steam can better act on the surface to be cleaned.

[0019] In some embodiments, the distance between the location of the scraping part on the working surface and the location of the steam outlet on the working surface is denoted as D3, where 3mm≤D3≤10mm.

[0020] Therefore, by controlling the distance between the scraping part and the steam outlet to be between 3mm and 10mm, the positions of the scraping part and the steam on the surface to be cleaned are kept at a reasonable level, so that the dirt can be scraped off in time after being dissolved by the steam, thus improving the cleaning effect.

[0021] In some embodiments, the cleaning mechanism further includes a gas supply component, the steam output component having a gas distribution chamber, the gas supply component communicating with the steam output port through the gas distribution chamber, the gas supply component being used to connect with a steam generating device, and the working surface being located on the side of the steam output component facing away from the gas supply component.

[0022] In some embodiments, the steam output component includes a first component and a second component, the second component cooperating with the first component and forming the gas distribution chamber between them, the gas delivery component being disposed on the side of the first component facing away from the gas distribution chamber, and the working surface being disposed on the side of the second component facing away from the gas distribution chamber.

[0023] This facilitates the formation of a steam distribution chamber in the steam output component, ensuring stable steam output outside the steam output port and improving the stability of steam cleaning.

[0024] In some embodiments, the cleaning mechanism further includes a connector having a first snap-fit ​​portion and a steam output component having a second snap-fit ​​portion, wherein the first snap-fit ​​portion and the second snap-fit ​​portion engage in a snap-fit ​​relationship.

[0025] Therefore, during structural assembly, the first snap-fit ​​part and the second snap-fit ​​part can be snapped together, which can effectively combine the connecting body and the steam output part, not only ensuring structural stability, but also facilitating the assembly between structures.

[0026] 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 preceding claims, the cleaning mechanism being at least partially disposed in the main housing.

[0027] The aforementioned steam cleaning device employs the cleaning mechanism described above, introducing a steam output component and a scraper. During the cleaning process, the working surface of the steam output component faces the surface to be cleaned, and steam is output through the steam outlet to dissolve dirt on the surface. Simultaneously, the scraper removes dirt or dissolved dirt from the surface, thus enhancing the cleaning capability of the equipment. Because the scraping part of the scraper is located on the working surface and in front of the steam outlet, 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.

[0028] 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.

[0029] Therefore, during assembly, the first fixing hole and the second fixing hole of the fastener can be aligned. This allows the operator to insert the fastener into the second fixing hole and the first fixing hole in sequence, achieving a quick and stable connection.

[0030] A cleaning device includes: a main unit including a roller brush; and the aforementioned steam cleaning device, wherein the main housing covers the roller brush, and the scraping portion is located on the side of the steam outlet facing away from the roller brush in the forward direction of the main unit.

[0031] The aforementioned cleaning equipment employs the cleaning mechanism described above, incorporating a steam output component and a scraper. During the cleaning process, the working surface of the steam output component faces the surface to be cleaned, and steam is output through its steam outlet 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 on the working surface and in front of the steam outlet, 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.

[0048] In some embodiments, please refer to Figures 1 to 3 This application provides a cleaning mechanism for installation on the main unit 60 of a cleaning device. The cleaning mechanism includes: a steam output component 10, including a working surface 15, on which a steam output port 11 is provided; and a scraping component 20, including a scraping part 21 for contacting the surface 70 to be cleaned, the scraping part 21 protruding from the working surface 15 and configured to be located in front of the steam output port 11 in the forward direction X of the main unit 60.

[0049] The aforementioned cleaning mechanism incorporates a steam output component 10 and a scraper component 20. During the cleaning process, the working surface 15 of the steam output component 10 faces the surface 70 to be cleaned, and steam is output through the steam outlet 11 of the steam output component 10 to dissolve 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 on the working surface 15 and in front of the steam outlet 11, the scraping part 21 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.

[0050] 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.

[0051] The scraping part 21 is disposed on the working surface 15, such that the scraping part 21 and the steam outlet 11 are located on the same surface of the steam output component 10. This allows the scraping part 21 to move along with the main unit 60 and scrape away dirt from the surface 70 while the steam output component 10 outputs steam to the surface to be cleaned 70, or simultaneously with the steam output component 10. Because the scraping part 21 is located in front of the steam outlet 11, it can reach the space in front of the surface while still providing steam output to the surface 70, reducing the chance of the steam output component 10 obstructing it. This allows the scraping part 21 to reach corners or the bottom edges of obstacles more frequently during cleaning, achieving thorough cleaning and reducing the chance of cleaning dead spots.

[0052] In addition, both the scraping part 21 and the steam outlet 11 are provided on the working surface 15. When the scraping part 21 contacts the surface 70 to be cleaned, the scraping part 21 can form a relatively closed space in front of the steam outlet 11, which can ensure that more steam is accurately applied to the surface 70 to be cleaned, reduce the leakage of steam, and greatly improve the cleaning effect.

[0053] In this context, the working surface 15 refers to the surface of the steam output component 10 facing the surface 70 to be cleaned. When the cleaning mechanism performs cleaning, the working surface 15 can face the surface to be inspected, so that both the steam output port 11 and the scraping part 21 can face the surface to be inspected, thereby allowing both the steam and the scraping part 21 to act on the surface 70 to be cleaned. Specifically, in some examples, when the steam output component 10 is being cleaned, the working surface 15 is the bottom of the steam output component 10.

[0054] Meanwhile, the scraping part 21 can be connected to the working surface 15 in various ways, such as, but not limited to, bolt connection, snap-fit, and bonding. Of course, the scraping part 20 and the steam output part 10 are integrally formed, for example, by injection molding, 3D printing, or other methods.

[0055] 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.

[0056] 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.

[0057] Further, please refer to Figure 3 and Figure 5 The scraper 20 also includes a fixing part 22 protruding from the scraping part 21. An assembly groove 16 is provided on the working surface 15, and the fixing part 22 is disposed in the assembly groove 16. Therefore, by providing the assembly groove 16 on the working surface 15, the scraper 20 is embedded in the steam output part 10 through the fixing part 22, ensuring stable installation of the scraper 20, reducing the risk of damage to the scraper 20 during the cleaning process, and ensuring the structural stability of the cleaning mechanism.

[0058] It should be noted that the assembly groove 16 refers to an inwardly recessed structure on the working surface 15. The fixing part 22 can be fixed in the assembly groove 16, so that the scraper 20 is stably installed on the working surface 15. The fixing part 22 can be fixed in the assembly groove 16 in various ways, such as, but not limited to, threaded connection, bonding, welding, etc. In some specific examples, the fixing part 22 and the scraper part 21 protruding from the assembly groove 16 on the working surface 15 can be formed by injection molding.

[0059] Meanwhile, the shape of the groove 16 can be varied, such as, but not limited to, circular, elliptical, and square shapes. Furthermore, the number of assembly grooves 16 and fixing parts 22 can be one or more. When there is only one assembly groove 16, it extends along the length of the steam output component 10; when there are multiple assembly grooves 16, they are spaced apart along the length of the steam output component 10.

[0060] In some embodiments, please refer to Figure 5The fixing part 22 protrudes from the end face of the scraping part 21, and the end face of the scraping part 21 includes an abutment surface 23. The abutment surface 23 is located along the thickness direction Z of the scraping part 21 on the side of the fixing part 22 facing the steam outlet 11, and the abutment surface 23 abuts against the working surface 15. Therefore, when the fixing part 22 is embedded in the assembly groove 16, the abutment surface 23 of the scraping part 21 can abut against the working surface 15 located between the assembly groove 16 and the steam outlet 11. In this way, during the cleaning process, the scraping part 21 can be supported on the side of the assembly groove 16 near the steam outlet 11, ensuring that the scraping part 21 is stably supported and preventing the scraping part 21 from bending on the side facing the steam outlet 11, which would affect the steam cleaning effect.

[0061] It should be noted that, in the thickness direction Z of the scraping part 21, the thickness of the end face of the scraping part 21 should be greater than the thickness of the fixing part 22, so that the part of the end face of the scraping part 21 that extends beyond the fixing part 22 can be the abutting surface 23.

[0062] The contact surface 23 can be located on the outer side of the fixing part 22 along the thickness direction Z of the scraping part 21, so that the contact surface 23 can abut against the working surface 15 on the side of the assembly groove 16 facing the steam outlet 11, preventing the scraping part 21 from bending along the side facing the steam outlet 11 during the cleaning process. This reduces the space occupied on the side where the steam outlet 11 is located, thereby avoiding affecting the steam output effect in the steam outlet 11 and thus improving the cleaning effect.

[0063] In some embodiments, please refer to Figure 5 The scraping part 21 includes a first surface 24, which is disposed facing the steam outlet 11 and configured to guide at least a portion of the steam ejected from the steam outlet 11 to the surface 70 to be cleaned. Therefore, during the cleaning process, when the scraping part 21 contacts the surface 70 to be cleaned in front of the steam outlet 11, the first surface 24 can block the steam outlet 11, guiding at least a portion of the steam, allowing the steam to act more effectively on the surface 70 to be cleaned, thus improving the dissolution effect of the dirt.

[0064] It should be noted that the first surface 24 refers to the surface of the scraping part 21 facing the steam outlet 11, so that at least a portion of the steam output from the steam outlet 11 can flow onto the surface 70 to be cleaned under the guidance of the first surface 24. The first surface 24 can have various designs, such as, but not limited to, a curved surface or a flat surface. When the first surface 24 is flat, it can be inclined relative to the vertical direction; and when the first surface 24 is curved, it can be a convex or concave curved surface.

[0065] Meanwhile, when there are multiple steam outlets 11 and each steam outlet 11 is spaced apart along the length of the steam output component 10, the first surface 24 can block at least some of the steam outlets 11, so that the steam output from most of the steam outlets 11 can be guided to the surface 70 to be cleaned under the action of the first surface 24.

[0066] Further, please refer to Figure 5 The distance between the first surface 24 and the center line Y of the steam outlet 11 is denoted as D1. The distance D1 gradually increases from the end of the scraping part 21 near the steam output component 10 to the end of the scraping part 21 away from the steam output component 10. Therefore, the further the first surface 24 is from the steam output component 10, the larger the distance between it and the center line Y of the steam outlet 11. This prevents the scraping part 21 from turning outwards during the cleaning process, which would result in incomplete cleaning. It also makes it easier for the scraping part 21 to remain in an outward-turned state during cleaning, improving the scraping effect. Simultaneously, the further the distance between the first surface 24 and the center line Y is from the steam output component 10, the larger the distance. This allows the steam to act on a larger area of ​​the surface 70 to be cleaned under the action of the first surface 24, improving cleaning efficiency.

[0067] It should be noted that the centerline Y of the steam outlet 11 refers to the geometric centerline of the steam outlet 11; of course, in some examples, the centerline Y of the steam outlet 11 may also be the axis of the steam outlet 11. In some examples, the centerline Y may also be perpendicular to the working surface 15.

[0068] Meanwhile, the first surface 24 can be an inclined plane or a concave arc surface, and the end of the first surface 24 near the steam output component 10 is closer to the steam output port 11 than the end of the first surface 24 near the surface to be cleaned 70.

[0069] In some embodiments, please refer to Figure 5 The scraping part 21 also includes a second surface 25, which is disposed opposite to the first surface 24 along the thickness direction Z of the scraping part 21. The distance between the first surface 24 and the second surface 25 is denoted as D2, which gradually decreases from the end of the scraping part 21 near the steam output member 10 to the end of the scraping part 21 away from the steam output member 10. Therefore, the scraping part 21 is thicker at the end near the steam output member 10 and thinner at the end near the surface 70 to be cleaned, making the connection between the scraping part 21 and the steam output member 10 more stable; at the same time, it also makes the end of the scraping part 21 in contact with the surface 70 to be cleaned more flexible, which is beneficial to improving the scraping effect.

[0070] Specifically, in some examples, when the cleaning mechanism is in the cleaning position, the second surface 25 may be perpendicular to the surface 70 to be cleaned.

[0071] In some embodiments, please refer to Figure 5The height of the scraping part 21 protruding from the working surface 15 is denoted as H, where 5mm ≤ H ≤ 10mm. Therefore, the height H of the scraping part 21 can be between 5mm and 10mm, ensuring sufficient contact between the scraping part 21 and the surface 70 to be cleaned. This improves the scraping ability of the scraping part 21 and enhances the cleaning effect. Simultaneously, it maintains a reasonable distance between the steam outlet 11 and the surface 70 to be cleaned, allowing the steam to act more effectively on the surface 70.

[0072] It should be noted that if the height of the scraping part 21 is too large, the steam outlet 11 will be too far from the surface to be cleaned 70, affecting the steam cleaning effect; if the height of the scraping part 21 is too small, the steam outlet 11 will be too close to the surface to be cleaned 70, affecting the output of steam in the steam outlet 11 and reducing the steam cleaning effect.

[0073] Therefore, the height H of the scraping section 21 can be between 5mm and 10mm, for example, but not limited to 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.

[0074] In some embodiments, please refer to Figure 5 The distance between the position of the scraping part 21 on the working surface 15 and the position of the steam outlet 11 on the working surface 15 is denoted as D3, where 3mm ≤ D3 ≤ 10mm. Therefore, controlling the distance between the scraping part 21 and the steam outlet 11 to be between 3mm and 10mm ensures that the positions of the scraping part 21 and the steam on the surface 70 are appropriately aligned, allowing the dirt dissolved by the steam to be promptly scraped away by the scraping part 21, thus improving the cleaning effect.

[0075] It should be noted that if the distance between the scraping part 21 and the steam outlet 11 is too large, it will take a relatively long time to scrape off the dissolved dirt, which may cause some of the dissolved dirt to solidify again, affecting the cleaning effect; if the distance between the scraping part 21 and the steam outlet 11 is too small, the scraping part 21 will affect the steam output effect of the steam outlet 11.

[0076] Therefore, the distance between the scraping part 21 and the steam outlet 11 in this embodiment can be between 3mm and 10mm, for example, but not limited to 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.

[0077] In some embodiments, please refer to Figure 4 and Figure 5The cleaning mechanism also includes a gas supply component 30. The steam output component 10 has a gas distribution chamber 12. The gas supply component 30 is connected to the steam output port 11 through the gas distribution chamber 12. The gas supply component 30 is used to connect to the steam generator. The working surface 15 is located on the side of the steam output component 10 facing away from the gas supply component 30.

[0078] 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.

[0079] The gas supply component 30 refers to the structure connecting the steam generator and the steam output component 10. 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.

[0080] 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.

[0081] Additionally, 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.

[0082] 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 working surface 15 is provided on the surface of the second component 14 facing away from the gas distribution chamber 12.

[0083] The first component 13 and the second component 14 can be connected by, but are not limited to, bolt connection, snap-fit, or adhesive.

[0084] In some embodiments, please refer to Figure 5 The steam output component 10 includes a first component 13 and a second component 14. The second component 14 cooperates with the first component 13, forming a gas distribution chamber 12 between them. The gas delivery component 30 is located on the side of the first component 13 facing away from the gas distribution chamber 12, and the working surface 15 is located on the side of the second component 14 facing away from the gas distribution chamber 12. This facilitates the formation of the gas distribution chamber 12 in the steam output component 10, ensuring stable steam output outside the steam output port 11 and improving the stability of steam cleanliness.

[0085] It should be noted that there are various ways to connect the first component 13 and the second component 14, such as, but not limited to, bolt connection, snap-fit, riveting, welding, and bonding. Of course, the first component 13 and the second component 14 can also be an integrated structure.

[0086] In some embodiments, please refer to Figure 1 and Figure 6 The cleaning mechanism also includes a connector 40, which has a first snap-fit ​​part 41 and a second snap-fit ​​part 17 on the steam output component 10. The first snap-fit ​​part 41 and the second snap-fit ​​part 17 are engaged in a snap-fit ​​configuration. Therefore, during structural assembly, the first snap-fit ​​part 41 and the second snap-fit ​​part 17 can be engaged in a snap-fit ​​configuration, effectively combining the connector 40 and the steam output component 10. This not only ensures structural stability but also facilitates assembly between structural components.

[0087] 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.

[0088] Meanwhile, the steam output component 10 can be connected to the connector 40 in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, welding, pin connection, and bonding.

[0089] When the cleaning mechanism also includes an air supply component 30, a limiting groove 45 can be provided on the connecting body 40, and the air supply component 30 is inserted into the limiting groove 45 on the connecting body 40. Simultaneously, the limiting groove 45 can engage with the conveying pipe 54, allowing the conveying pipe 54 to communicate with 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 when the steam output component 10 and the scraper 20 move to the avoidance position, the air supply component 30 can be inserted into the limiting groove 45. Here, the cleaning position refers to the position where the steam output component 10 and the scraper 20 are relatively closer to the surface 70 to be cleaned, allowing for cleaning operations on the surface 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 70 to be cleaned.

[0090] It should also be noted that the structures of the first snap-fit ​​part 41 and the second snap-fit ​​part 17 can have various designs. For example, the first snap-fit ​​part 41 may include a snap plate and a slot provided on the surface of the snap plate, and the second snap-fit ​​part 17 may include a protrusion. The protrusion of the second snap-fit ​​part 17 can be inserted into the slot of the snap plate to achieve snap-fit. Alternatively, the first snap-fit ​​part 41 may include a snap plate and a protrusion provided on the surface of the snap plate, and the second snap-fit ​​part 17 may include a slot. The protrusion on the snap plate can be inserted into the slot to achieve snap-fit.

[0091] 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.

[0092] Additionally, in some examples, the connector 40 may be connected to the side of the steam output component 10 facing away from the working surface 15.

[0093] In some embodiments, please refer to Figure 1 and Figure 6 The connector 40 has a positioning protrusion 42, and the steam output component 10 has a positioning hole 18. The positioning protrusion 42 passes through the positioning hole 18. Therefore, when the connector 40 and the steam output component 10 are assembled, the positioning protrusion 42 on the connector 40 can pass through the positioning hole 18, allowing for quick and effective positioning of both, thus facilitating a stable and rapid connection of the steam output component 10. Simultaneously, the cooperation between the positioning protrusion 42 and the positioning hole 18 also improves the stability of the connection between the connector 40 and the steam output component 10.

[0094] 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.

[0095] In some embodiments, please refer to Figure 1 and Figure 6 The connector 40 is equipped with a fixing member 43, which has a first fixing hole 44. The steam output component 10 has a second fixing hole 19. The first fixing hole 44 and the second fixing hole 19 of the fixing member 43 are arranged opposite to each other. Therefore, during assembly, the first fixing hole 44 and the second fixing hole 19 of the fixing member 43 can be aligned, allowing the operator to insert the fasteners sequentially into the second fixing hole 19 and the first fixing hole 44, achieving a quick and stable connection.

[0096] 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 with split threads, so that the fastener can be a bolt with a nut.

[0097] 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.

[0098] In some embodiments, please refer to Figure 4 and Figure 9 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.

[0099] 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, the working surface 15 of the steam output component 10 faces the surface 70 to be cleaned, and steam is output through the steam outlet 11 of the steam output component 10 to dissolve 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 on the working surface 15 and in front of the steam outlet 11, the scraping part 21 can achieve edge cleaning, effectively improving the problem of cleaning equipment struggling to clean corners, reducing the likelihood of dead corners during cleaning, further enhancing the cleaning effect, and improving the user experience.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Further, please refer to Figure 9The 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.

[0104] 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.

[0105] 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.

[0106] 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 the steam output component 10 is 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 in 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.

[0107] In some embodiments, please refer to Figure 7 and Figure 8 This application provides a cleaning device, which includes: a main unit 60 including a roller brush 61; and a steam cleaning device, wherein 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.

[0108] The aforementioned cleaning equipment employs the cleaning mechanism described above, introducing a steam output component 10 and a scraper component 20. During the cleaning process, the working surface 15 of the steam output component 10 faces the surface 70 to be cleaned, and steam is output through the steam outlet 11 of the steam output component 10 to dissolve 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 on the working surface 15 and in front of the steam outlet 11, the scraping part 21 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.

[0109] 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 corners in front of the wall, 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 70 to be cleaned; it can have a roller-like structure and can rotate around its own axis.

[0110] 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.

[0111] 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.
