Description

Technical Field

[0001] The present application relates to the technical field of vacuum cleaners, and in particular to a suction wand for a vacuum cleaner. Background Art

[0002] The conventional vacuum cleaner suction wand includes a suction wand frame and two rubber strips disposed on opposite sides of the frame. Each of the opposing sides of the frame is provided with a full-length recessed groove, into which the rubber strips are secured. In this suction wand structure, the recessed groove maintains its cross-section during installation of the rubber strips. One side of the rubber strip is adapted to fit the recessed groove cross-section, and the rubber strip is gradually inserted into the recess along its length. This can easily cause the rubber strips to become stuck during installation, resulting in low installation efficiency and increased assembly time. Summary of the Invention

[0003] In order to solve the above-mentioned problems, the present application provides a suction scraper for a vacuum cleaner, which has an ingenious design and a simple structure. In the present application, the slot forming member is rotatably connected to the suction scraper frame body, so that the slot forming member can be rotated relative to the suction scraper frame body, thereby making the cross-section of the first slot larger or smaller. When it is necessary to install a long rubber strip, the slot forming member is rotated to enlarge the cross-section of the first slot, thereby facilitating the installation of the long rubber strip and avoiding jamming. After the long rubber strip is installed in the first slot position, the slot forming member is rotated to reduce the cross-section of the first slot, and then the pressing member is used to limit the rotation of the slot forming member, and finally the long rubber strip is stuck in the first slot. The long rubber strip in the present application is easy to install and not prone to jamming. The technical solutions adopted in the application are as follows:

[0004] A suction wand for a vacuum cleaner, comprising:

[0005] The suction scraper frame assembly comprises a suction scraper frame body, two slot forming members respectively provided on opposite sides of the suction scraper frame body, the suction scraper frame body and the slot forming member are both in the shape of an elongated strip, and opposite sides of the suction scraper frame body are respectively provided with a first rotating connection portion whose length direction is consistent with the length direction of the suction scraper frame body, the slot forming member is provided with a second rotating connection portion adapted to the first rotating connection portion, the first rotating connection portion and the second rotating connection portion are connected to form a rotating pair, so that the suction scraper frame body and the slot forming member are rotatably connected; the slot forming member further comprises a slot portion, the slot portion is arranged opposite to the side edge of the suction scraper frame body, and the slot portion and the side edge of the suction scraper frame body are combined to form a first slot;

[0006] A long rubber strip, comprising a long rubber strip body and a rubber strip mounting portion located on one side of the long rubber strip body, wherein the rubber strip mounting portion is embedded in the first card slot;

[0007] Short rubber strips, the short rubber strips are provided at both ends of the suction scraper body in the length direction;

[0008] The clamping parts are arranged at intervals along the length direction of the suction scraper body, and the clamping parts include a fixing part and clamping parts respectively located at the opposite ends of the fixing part. The fixing part is installed on the top of the suction scraper body, and one side of the clamping part abuts against the side of the slot part away from the first slot to limit the rotation of the slot forming part.

[0009] The slot-forming member is rotatably connected to the suction scraper body, allowing the slot-forming member to rotate relative to the suction scraper body, thereby increasing or decreasing the cross-section of the first slot. When installing a long rubber strip, the slot-forming member is rotated to increase the cross-section of the first slot, facilitating installation of the long rubber strip and preventing it from getting stuck. Once the long rubber strip is positioned in the first slot, the slot-forming member is rotated to reduce the cross-section of the first slot. The compression member then restricts the rotation of the slot-forming member, ultimately securing the long rubber strip in the first slot. The structure of the suction scraper assembly in this application facilitates installation of the long rubber strip and reduces the risk of it getting stuck.

[0010] In some embodiments, the cross-section of the first card slot is a convex shape with a larger interior and a smaller opening, the rubber strip mounting portion is cooperatively inserted into the interior of the first card slot, and the long rubber strip body extends outward from the opening of the first card slot.

[0011] By designing the cross-section of the first card slot to be a convex shape with a larger interior and a smaller opening, and the rubber strip mounting portion being adapted to the cross-section of the first card slot, the long rubber strip will not detach from the first card slot after being installed in the first card slot, and the long rubber strip and the first card slot are movably connected, which is convenient for assembly and disassembly, and does not require other fixings or connecting parts.

[0012] In some embodiments, a fixing assembly for fixing the short rubber strip is further included, and the fixing assembly includes two first fixing plates and a second fixing plate, both of which are L-shaped. The first fixing plate includes a first mounting edge and a first clamping edge, and the second fixing plate includes a second mounting edge and a second clamping edge. The first mounting edge is installed at the bottom of both ends of the suction scraper body in the length direction, and the second mounting edge is installed at the top of both ends of the suction scraper body in the length direction. The first clamping edge and the second clamping edge are combined to form a second clamping groove, and the short rubber strip is clamped in the second clamping groove.

[0013] By setting a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are combined to form a second card slot, which provides installation space for the short rubber strip. The short rubber strip is stuck in the second card slot. The short rubber strip and the second card slot are movably connected, which is convenient for assembly and disassembly without the need for other fixing parts or connecting parts.

[0014] In some embodiments, the second mounting edge and the second clamping edge are perpendicular to each other, and the first clamping edge is tilted relative to the second clamping edge so that the cross section of the second clamping slot is wedge-shaped with a larger inner portion and a smaller opening.

[0015] By tilting the first clipping edge of the first fixing plate relative to the second clipping edge, a wedge-shaped groove with a larger interior and a smaller opening is formed between the first clipping edge and the second clipping edge, thereby providing installation space for the short rubber strip. The structure of this installation space (wedge-shaped groove) is simple and easy to process and manufacture.

[0016] In some embodiments, both ends of the second clamping edge in the width direction of the suction scraper body are provided with a covering portion, and the covering portion covers the end of the first clamping slot to prevent the long rubber strip from sliding out of the first clamping slot.

[0017] By arranging the sealing parts at both ends of the second clamping edge, the sealing parts limit the long rubber strip and prevent the long rubber strip in the first clamping slot from sliding out.

[0018] In some embodiments, it further includes an auxiliary wheel assembly installed at both ends of the suction scraper body in the length direction, the auxiliary wheel assembly includes an L-shaped third fixing plate and an auxiliary wheel, the third fixing plate includes a third mounting edge and an auxiliary wheel mounting edge, the third mounting edge and the auxiliary wheel mounting edge are arranged perpendicular to each other, the third mounting edge is installed at the top of the end of the suction scraper body in the length direction, and the auxiliary wheel mounting edge is installed with the auxiliary wheel.

[0019] By setting up the auxiliary wheel assembly, the auxiliary wheel assembly provides support for the suction scraper, controlling the distance between the suction scraper frame assembly and the surface to be cleaned, so that the suction scraper frame assembly and the surface to be cleaned are at an appropriate distance, avoiding the reduction of the dust collection effect due to too far distance, and avoiding the long and short rubber strips being deformed too much and causing damage due to too close distance.

[0020] In some embodiments, at least two auxiliary wheels are installed on one auxiliary wheel mounting edge, and the two auxiliary wheels are distributed along the width direction of the suction scraper body.

[0021] By arranging at least two auxiliary wheels at each end of the suction scraper, and at least two auxiliary wheels at the same end are arranged along the width direction of the suction scraper, the auxiliary wheels on the suction scraper provide all-round support for the suction scraper, so that the suction scraper frame assembly as a whole is parallel to the surface to be cleaned, preventing the suction scraper frame assembly as a whole from tilting relative to the surface to be cleaned, thereby ensuring a good dust collection effect.

[0022] In some embodiments, the auxiliary wheel is installed on a side of the auxiliary wheel installation edge close to the suction scraper body.

[0023] By installing the training wheel on the inner side of the training wheel mounting edge, the training wheel can be protected to prevent the training wheel from colliding with other objects, while also reducing the risk of objects being entangled in the training wheel.

[0024] In some embodiments, the auxiliary wheel assembly further includes an adjusting member and an elastic member, wherein the adjusting member is pressed against the top of the third mounting edge, and the adjusting member is screwed to the suction scraper body, and the elastic member is pressed between the bottom of the third mounting edge and the top of the suction scraper body, and the elastic member provides support for the third fixing plate, and the distance between the third mounting edge and the suction scraper body can be adjusted by screwing the adjusting member.

[0025] By setting an adjusting member and an elastic member, the elastic member provides a force for the third fixing plate to move away from the suction scraper body, and the adjusting member is pressed on the top of the third mounting edge of the third fixing plate. In this way, the distance between the third mounting edge and the suction scraper body can be adjusted by simply turning the adjusting member clockwise or counterclockwise, so that the suction scraper assembly is at an appropriate distance from the surface to be cleaned, avoiding the reduction in dust collection effect due to too far a distance, and avoiding the long and short rubber strips from being too close, which may cause large deformation and damage.

[0026] In some embodiments, the auxiliary wheel assembly further includes a guide column, which is mounted on the top of the suction rack body. The third mounting edge is provided with a through-hole adapted to the guide column, the guide column is passed through the through-hole, and the elastic member is sleeved outside the guide column.

[0027] By arranging the elastic part outside the guide column, the guide column guides the deformation of the elastic part and the movement of the third fixed plate. The guide column limits the elastic part to deform only along the length direction of the guide column, thereby preventing the elastic part from deflecting. At the same time, the guide column limits the third fixed plate to move only along the length direction of the guide column.

[0028] The present application provides a vacuum cleaner with a suction wand having at least one of the following beneficial effects:

[0029] 1. The present application provides a suction scraper for a vacuum cleaner. The suction scraper frame body is rotatably connected to a slot-forming member, allowing the slot-forming member to rotate relative to the suction scraper frame body, thereby increasing or decreasing the cross-section of the first slot. When a long rubber strip needs to be installed, the slot-forming member is rotated to increase the cross-section of the first slot, thereby facilitating the installation of the long rubber strip and preventing it from getting stuck during installation. After the long rubber strip is installed in the first slot, the slot-forming member is rotated to reduce the cross-section of the first slot. The rotation of the slot-forming member is then restricted by a pressing member, ultimately trapping the long rubber strip in the first slot. The structure of the suction scraper frame assembly in the present application facilitates the installation of the long rubber strip and prevents it from getting stuck.

The short rubber strip and the second card slot are movably connected, which is convenient for assembly and disassembly, and does not require other fixing parts or connecting parts.

[0032] 4. The present application provides a suction pick for a vacuum cleaner, which forms a wedge-shaped groove with a larger interior and a smaller opening between the first clamping edge and the second clamping edge by tilting the first clamping edge of the first fixing plate relative to the second clamping edge, thereby providing installation space for the short rubber strip. The structure of this installation space (wedge-shaped groove) is simple and easy to process and manufacture.

[0033] 5. The present application provides a suction pick for a vacuum cleaner, in which a sealing portion is provided at both ends of the second clamping edge. The sealing portion serves to limit the long rubber strip, thereby preventing the long rubber strip in the first clamping slot from slipping out.

[0034] 6. The present application provides a suction scraper for a vacuum cleaner. By setting an auxiliary wheel assembly, the auxiliary wheel assembly provides support for the suction scraper, controls the distance between the suction scraper frame assembly and the surface to be cleaned, so that the suction scraper frame assembly and the surface to be cleaned are at an appropriate distance, avoiding the reduction of the dust collection effect due to the distance being too far, and avoiding the long and short rubber strips being too deformed and damaged due to the distance being too close.

[0058] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0059] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0060] refer to Figures 1-13 The present application provides a suction scraper for a vacuum cleaner, comprising: a suction scraper frame assembly 1, a long rubber strip 2, a short rubber strip 3 and a pressing member 4; the suction scraper frame assembly 1 comprises a suction scraper frame body 11, two slot forming members 12 respectively provided on opposite sides of the suction scraper frame body 11, the suction scraper frame body 11 and the slot forming member 12 are both long strip-shaped, and opposite sides of the suction scraper frame body 11 are respectively provided with a first rotating connection part 111 with a length direction consistent with the length direction of the suction scraper frame body 11, the slot forming member 12 is provided with a second rotating connection part 121 adapted to the first rotating connection part 111, the first rotating connection part 111 and the second rotating connection part 121 are connected to form a rotating pair, so that the suction scraper frame body 11 and the slot forming member 12 are rotatably connected; the slot forming member 12 also includes a slot part 122, the slot part 122 is arranged opposite to the side edge of the suction scraper frame body 11, and the slot part 122 is combined with the side edge of the suction scraper frame body 11 to form a first slot 13;

[0061] The long rubber strip 2 includes a long rubber strip body 21 and a rubber strip mounting portion 22 located on one side of the long rubber strip body 21, and the rubber strip mounting portion 22 is embedded in the first card slot 13; the short rubber strip 3 is provided at both ends of the suction scraper body 11 in the length direction; the clamping member 4 is arranged at intervals along the length direction of the suction scraper body 11, and the clamping member 4 includes a fixing portion 41 and clamping portions 42 respectively located at the opposite ends of the fixing portion 41, and the fixing portion 41 is installed on the top of the suction scraper body 11, and one side of the clamping portion 42 abuts against the side of the card slot portion 122 away from the first card slot 13 to limit the rotation of the card slot forming member 12.

[0062] Specifically, in one embodiment, the cross-section of the first rotating connection portion 111 is cylindrical, and the cross-section of the second rotating connection portion 121 is a C-shaped slot. The C-shaped slot matches the cross-section of the first rotating connection portion 111, and the first rotating connection portion 111 is engaged with the second rotating connection portion 121. The connection mechanism formed by the combination of the first rotating connection portion 111 and the second rotating connection portion 121 is similar to a ball joint, except that it has only one degree of rotational freedom. It is understood that in other embodiments, the cross-section of the first rotating connection portion 111 is a C-shaped slot, and the cross-section of the second rotating connection portion 121 is cylindrical, and the C-shaped slot matches the cross-section of the second rotating connection portion 121.

[0063] Furthermore, it should be understood that the suction scraper assembly 1, the long rubber strips 2 located on both sides of the suction scraper assembly 1, and the short rubber strips 3 located at both ends of the suction scraper assembly 1 enclose a dust collection space, and an opening is formed in the suction scraper body 11, which is connected to the dust collection space. During normal use, a connector for connecting to a vacuum cleaner suction pipe is fixed at the opening of the suction scraper body 11, and the connector is connected to the dust collection space through the opening.

[0064] It is understood that the rotatable connection between the slot forming member 12 and the suction scraper body 11 allows the slot forming member 12 to rotate relative to the suction scraper body 11, thereby allowing the cross-section of the first slot 13 to be enlarged or reduced. When the long rubber strip 2 needs to be installed, the slot forming member 12 is rotated to enlarge the cross-section of the first slot 13, thereby facilitating the installation of the long rubber strip 2 and preventing the long rubber strip 2 from getting stuck during installation. After the long rubber strip 2 is installed in the first slot 13, the slot forming member 12 is rotated to reduce the cross-section of the first slot 13, and then the pressing member 4 is used to limit the rotation of the slot forming member 12, ultimately clamping the long rubber strip 2 in the first slot 13. The structure of the suction scraper assembly 1 in the present application makes the long rubber strip 2 easy to install and less likely to get stuck.

[0065] refer to Figure 2-Figure 4 、 Figures 8-10 In one embodiment, the cross-section of the first slot 13 is a convex shape with a larger interior and a smaller opening. The rubber strip mounting portion 22 is cooperatively inserted into the interior of the first slot 13, and the long rubber strip body 21 extends outward from the opening of the first slot 13. In other embodiments, the cross-section of the first slot 13 can be other shapes, such as a wedge-shaped slot or a dovetail slot.

[0066] It is easy to understand that by designing the cross-section of the first card slot 13 to be a convex shape with a larger interior and a smaller opening, and the rubber strip mounting portion 22 is adapted to the cross-section of the first card slot 13, the long rubber strip 2 will not detach from the first card slot 13 after being installed in the first card slot 13, and the long rubber strip 2 and the first card slot 13 are movably connected, which is convenient for assembly and disassembly, and does not require other fixings or connectors.

[0067] refer to Figure 1 、 Figure 5-Figure 7 、 Figures 9-13 In one embodiment, the suction scraper also includes a fixing component 5 for fixing the short rubber strip 3. The fixing component 5 includes two L-shaped first fixing plates 51 and a second fixing plate 52. The first fixing plate 51 includes a first mounting edge 511 and a first clamping edge 512. The second fixing plate 52 includes a second mounting edge 521 and a second clamping edge 522. The first mounting edge 511 is installed at the bottom of both ends of the suction scraper body 11 in the length direction, and the second mounting edge 521 is installed at the top of both ends of the suction scraper body 11 in the length direction. The first clamping edge 512 and the second clamping edge 522 are combined to form a second clamping groove 53, and the short rubber strip 3 is clamped in the second clamping groove 53.

[0068] Specifically, the cross-sectional shape of the second slot 53 can refer to the first slot 13, and can be a convex slot with a larger interior and a smaller opening, or a wedge-shaped slot or a dovetail slot, etc. In other embodiments, the short rubber strip 3 can also be detachably fixed to both ends of the suction rack assembly 1 by screws, bolts, etc.

[0069] It can be understood that by setting the first fixing plate 51 and the second fixing plate 52, the first fixing plate 51 and the second fixing plate 52 are combined to form a second card slot 53, which provides installation space for the short rubber strip 3. The short rubber strip 3 is stuck in the second card slot 53. The short rubber strip 3 and the second card slot 53 are movably connected, which is convenient for assembly and disassembly, and does not require other fixing parts or connecting parts.

[0070] refer to Figure 6 、 Figure 7 、 Figures 9-12 In one embodiment, the second mounting edge 521 and the second clamping edge 522 are arranged perpendicular to each other, and the first clamping edge 512 is arranged obliquely relative to the second clamping edge 522, so that the cross-section of the second clamping groove 53 is a wedge-shaped groove with a larger inner portion and a smaller opening. In other words, the second clamping groove 53 is a wedge-shaped groove.

[0071] It is worth noting that by tilting the first clamping edge 512 of the first fixing plate 51 relative to the second clamping edge 522, a wedge-shaped groove with a larger interior and a smaller opening is formed between the first clamping edge 512 and the second clamping edge 522, thereby providing installation space for the short rubber strip 3. The structure of this installation space (wedge-shaped groove) is simple and easy to process and manufacture.

[0072] refer to Figure 6 、 Figure 7 、 Figure 13In one embodiment, both ends of the second clamping edge 522 along the width direction of the suction scraper body 11 are provided with a cover portion 5221. The cover portion 5221 covers the end of the first clamping slot 13 to prevent the long rubber strip 2 from slipping out of the first clamping slot 13. By providing the cover portions 5221 at both ends of the second clamping edge 522, the cover portions 5221 limit the long rubber strip 2 and prevent it from slipping out of the first clamping slot 13.

[0073] refer to Figure 1 、 Figure 5 、 Figure 11-13 In one embodiment, the suction scraper also includes an auxiliary wheel assembly 6 installed at both ends of the suction scraper frame body 11 in the length direction. The auxiliary wheel assembly 6 includes an L-shaped third fixing plate 61 and an auxiliary wheel 62. The third fixing plate 61 includes a third mounting edge 611 and an auxiliary wheel mounting edge 612. The third mounting edge 611 and the auxiliary wheel mounting edge 612 are arranged perpendicular to each other. The third mounting edge 611 is installed at the top of the end of the suction scraper frame body 11 in the length direction, and the auxiliary wheel mounting edge 612 is installed with the auxiliary wheel 62.

[0074] It should be noted that by setting the auxiliary wheel assembly 6, the auxiliary wheel assembly 6 provides support for the suction scraper, controlling the distance between the suction scraper frame assembly 1 and the surface to be cleaned, so that the suction scraper frame assembly 1 and the surface to be cleaned are at an appropriate distance, avoiding the reduction of the dust collection effect due to the distance being too far, and at the same time avoiding the long rubber strip 2 and the short rubber strip 3 being deformed significantly due to the distance being too close, resulting in damage.

[0075] refer to Figure 1 、 Figure 5 、 Figure 11-13 In one embodiment, at least two auxiliary wheels 62 are installed on an auxiliary wheel mounting edge 612 , and the two auxiliary wheels 62 are distributed along the width direction of the suction scraper body 11 .

[0076] It is worth noting that by providing at least two auxiliary wheels 62 at each end of the suction scraper, and at least two auxiliary wheels 62 at the same end are arranged along the width direction of the suction scraper, the auxiliary wheels 62 on the suction scraper provide all-round support for the suction scraper, so that the suction scraper frame assembly 1 as a whole is parallel to the surface to be cleaned, preventing the suction scraper frame assembly 1 as a whole from tilting relative to the surface to be cleaned, thereby ensuring a good dust collection effect.

[0077] refer to Figure 1 、 Figure 5 、 Figure 11-13 In one embodiment, the auxiliary wheel 62 is mounted on the side of the auxiliary wheel mounting edge 612 close to the suction scraper body 11. By mounting the auxiliary wheel 62 on the inner side of the auxiliary wheel mounting edge 612, the auxiliary wheel 62 can be protected from colliding with other objects and the risk of objects being entangled in the auxiliary wheel 62 can be reduced.

[0078] refer to Figure 1 、 Figure 5 、 Figure 11-13 In one embodiment, the auxiliary wheel assembly 6 further includes an adjusting member 63 and an elastic member 64. The adjusting member 63 is pressed against the top of the third mounting edge 611, and the adjusting member 63 is screwed to the suction scraper body 11. The elastic member 64 is pressed between the bottom of the third mounting edge 611 and the top of the suction scraper body 11. The elastic member 64 provides support for the third fixing plate 61. The distance between the third mounting edge 611 and the suction scraper body 11 can be adjusted by screwing the adjusting member 63.

[0079] Specifically, there is at least one elastic member 64 at the top of one end of the suction scraper body 11. In this application, a solution with two elastic members 64 is presented. The two elastic members 64 are respectively arranged on both sides of the adjustment member 63 along the length direction of the suction scraper body 11, and can provide stable support for the third fixed plate 61.

[0080] It can be understood that by providing the adjusting member 63 and the elastic member 64, the elastic member 64 provides a force for the third fixing plate 61 to move away from the suction scraper body 11, and the adjusting member 63 is pressed on the top of the third mounting edge 611 of the third fixing plate 61, so that the distance between the third mounting edge 611 and the suction scraper body 11 can be adjusted by simply turning the adjusting member 63 clockwise or counterclockwise, so that the suction scraper assembly 1 is at an appropriate distance from the surface to be cleaned, avoiding the reduction of the dust collection effect due to the distance being too far, and avoiding the long rubber strip 2 and the short rubber strip 3 being deformed too much and damaged due to the distance being too close.

[0081] refer to Figure 1 、 Figure 5 、 Figure 11-13 In one embodiment, the auxiliary wheel assembly 6 further includes a guide post 65, which is mounted on the top of the suction scraper body 11. The third mounting edge 611 is provided with a through-hole adapted to the guide post 65. The guide post 65 is inserted through the through-hole, and the elastic member 64 is sleeved on the outside of the guide post 65. By sleeved on the outside of the guide post 65, the guide post 65 guides both the deformation of the elastic member 64 and the movement of the third fixing plate 61. The guide post 65 restricts the elastic member 64 from deforming only along the length of the guide post 65, thereby preventing the elastic member 64 from deflecting. At the same time, the guide post 65 restricts the third fixing plate 61 from moving only along the length of the guide post 65, thereby preventing the auxiliary wheel 62 from tilting. This ensures that the suction scraper assembly 1 is at an appropriate distance from the surface to be cleaned, thereby ensuring a good vacuuming effect.

[0082] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
