Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a vacuum cleaner head and a vacuum cleaner. Background Technology

[0002] Vacuum cleaners are common cleaning tools in daily life. Vacuum cleaners usually have an air intake. When using them, you point the air intake at the area that needs to be cleaned. After turning on the vacuum cleaner, a negative pressure is generated at the air intake, which sucks in pollutants such as dust mites.

[0003] However, when encountering relatively stubborn stains, the negative pressure generated at the suction port of the vacuum cleaner is insufficient, making it difficult to remove the stains. In some usage environments, such as when cleaning bed sheets, it is not necessary to generate a large negative pressure at the suction port. If a large negative pressure is generated at the suction port, the bed sheet is easily affected by the negative pressure and sucked towards the suction port, affecting the movement of the vacuum cleaner on the bed sheet. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the negative pressure at the air intake of the vacuum cleaner is difficult to change according to the usage conditions in the prior art, thereby providing a vacuum cleaner head and a vacuum cleaner.

[0005] A vacuum cleaner head includes:

[0006] A dust hood includes at least one opening that forms an air intake.

[0007] A support member is disposed inside the dust collection hood, and the support member has at least a first working position extending out of the opening.

[0008] The support member has at least two sub-working positions that extend out of the opening at different distances in the first working position.

[0009] The support member is slidably connected to the dust collection hood.

[0010] The vacuum cleaner head also includes:

[0011] An adjustment frame is mounted on the dust collection hood, and a limiting groove is provided on the adjustment frame. The support member is slidably connected to the limiting groove.

[0012] The support member includes:

[0013] The bracket is slidably connected to the adjusting frame;

[0014] A roller is rotatably connected to the bracket, and the roller is located at the end of the bracket away from the air intake.

[0015] The vacuum cleaner head also includes:

[0016] An adjusting wheel is rotatably connected to the adjusting frame, and a support member is rotatably connected to the adjusting wheel, with the support member and the adjusting wheel being threaded together.

[0017] The vacuum cleaner head also includes:

[0018] The positioning column is slidably connected to the adjusting frame and / or the dust cover, and the adjusting wheel and / or the support member are provided with multiple gear holes.

[0019] The adjusting frame is provided with an installation cylinder, and the positioning post is located inside the installation cylinder. One end of the installation cylinder is open and faces the adjusting wheel. A limiting elastic element is provided between the positioning post and the bottom of the installation cylinder.

[0020] The wall of the gear shift hole is arc-shaped and forms a guide arc surface connecting to the outside of the gear shift hole.

[0021] The dust collection hood has a first connection hole and a second connection hole. The positioning bolt passes through the first connection hole and the second connection hole in sequence and is then tightened.

[0022] The dust cover is provided with a limiting part, which includes a limiting slot, and the adjusting frame is provided with a snap-fit ​​part that adapts to the limiting slot.

[0023] The dust cover is provided with a limiting protrusion, which extends in the direction pointing to the limiting slot.

[0024] The dust cover has a through hole, and the adjusting wheel is exposed through at least part of the through hole.

[0025] A vacuum cleaner, comprising:

[0026] The vacuum cleaner head described in any of the above solutions;

[0027] A connecting rod is connected to the vacuum cleaner head, and the connecting rod has an air intake channel that is connected to the air intake.

[0028] The technical solution of this invention has the following advantages:

[0029] 1. The present invention provides a vacuum cleaner head, comprising: a vacuum hood, including at least one opening forming an air intake; and a support member disposed within the vacuum hood, the support member having at least a first working position extending out of the opening.

[0030] During routine vacuuming, the support component of the vacuum cleaner head is in its first working position with the suction port extended from the dust hood. At this position, due to the support component, there is a certain distance between the suction port and the surface to be cleaned. This increases the airflow volume, decreases the air velocity, and relatively reduces the negative pressure at the suction port. When the support component is retracted from the dust hood or removed, the distance between the suction port and the surface to be cleaned decreases. This reduces the airflow volume, increases the air velocity, and relatively increases the negative pressure at the suction port. Therefore, by adjusting the distance between the suction port and the surface to be cleaned using the support component, the negative pressure at the suction port can be adjusted, allowing the vacuum cleaner head to change the negative pressure at the suction port according to different usage environments.

[0031] 2. The vacuum cleaner head provided by the present invention has at least two sub-working positions in the first working position where the support member extends out of the opening at different distances.

[0032] When the support extends to form the opening of the air intake, the distance between the air intake and the surface to be cleaned increases. This solution provides multiple sub-working positions with different distances, thereby achieving multi-level adjustment of the air pressure at the air intake.

[0033] 3. The vacuum cleaner head provided by the present invention further includes: an adjustment frame, the adjustment frame being disposed on the vacuum cover, the adjustment frame being provided with a limiting groove, and the support member being slidably connected to the limiting groove.

[0034] The support is slidably connected to the adjustment frame. When the limit groove on the adjustment frame is worn or otherwise damaged, the adjustment frame can be replaced directly.

[0035] 4. The vacuum cleaner head provided by the present invention includes a support member comprising: a bracket slidably connected to the adjustment frame; and a roller rotatably connected to the bracket, wherein the roller is located at the end of the bracket away from the air intake.

[0036] By using rollers to support the air intake at a certain distance from the cleaning surface, the rollers can roll when the vacuum cleaner head is moved, thereby reducing the moving resistance of the vacuum cleaner head, improving the smoothness of vacuuming, and enhancing the user experience.

[0037] 5. The vacuum cleaner head provided by the present invention further includes: an adjusting wheel rotatably connected to the adjusting frame, a support member rotatably connected to the adjusting wheel, and the support member and the adjusting wheel being threaded together.

[0038] The rotational motion of the adjusting wheel is transmitted to the support member, which is slidably connected to the adjusting frame. Therefore, the support member itself cannot rotate relative to the adjusting frame, thus converting the rotational motion into sliding motion relative to the adjusting frame.

[0039] 6. The vacuum cleaner head provided by the present invention further includes: a positioning post, which is slidably connected to the adjusting frame and / or the vacuum cover, and the adjusting wheel and / or the support member is provided with a plurality of gear holes.

[0040] When the positioning pin is inserted into different gear holes, it can limit the gear holes, thereby preventing the adjustment wheel or support from continuing to move. After the user adjusts the support to the appropriate gear, the positioning pin positions the support so that it can maintain the current height of the vacuum cleaner head.

[0041] 7. The vacuum cleaner head provided by the present invention has an installation cylinder on the adjustment frame, a positioning post inside the installation cylinder, one end of the installation cylinder being open and facing the adjustment wheel, and a limiting elastic element being provided between the positioning post and the bottom of the installation cylinder.

[0042] The gear position hole is located on the adjusting wheel. The limiting elastic element can support the positioning post, keeping the positioning post inserted into the gear position hole and preventing the adjusting wheel from rotating.

[0043] 8. The vacuum cleaner head provided by the present invention has an arc-shaped hole wall that forms a guide arc surface connecting the outside of the hole.

[0044] Since the positioning pin is inserted into the gear position hole and is supported by the limiting elastic element, the adjusting wheel cannot break through the restriction of the positioning pin and rotate without the action of external force. In this solution, when the adjusting wheel rotates under the action of external force, the end of the positioning pin slides out of the gear position hole along the guide arc surface, so that the distance of the support extending from the gear position can be adjusted under the action of external force.

[0057] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] Example 1

[0059] This invention provides a vacuum cleaner head, such as Figure 1 As shown, the device includes: a dust cover 1, comprising at least one opening forming an air intake 16; and a support member 2, disposed within the dust cover 1, the support member 2 having at least a first working position extending beyond the opening. During routine vacuuming, the support member 2 is in the first working position extending beyond the air intake 16 of the dust cover 1. At this time, due to the supporting effect of the support member 2, there is a certain distance between the air intake 16 and the surface to be cleaned, resulting in increased airflow, decreased air velocity, and a relatively lower negative pressure at the air intake 16. When the support member 2 is retracted from the dust cover 1 or removed, the distance between the air intake 16 and the surface to be cleaned decreases, the airflow at the air intake 16 decreases, the air velocity increases, and the relatively higher negative pressure at the air intake 16. Therefore, by adjusting the distance between the air intake 16 and the surface to be cleaned through the support member 2, the magnitude of the negative pressure formed at the air intake 16 can be adjusted, allowing the vacuum cleaner head to change the negative pressure at the air intake 16 according to different usage environments.

[0060] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2 As shown, the support member 2 has at least two sub-working positions extending from the opening at different distances in the first working position. When the support member 2 extends out of the opening forming the air intake 16, the distance between the air intake 16 and the surface to be cleaned increases. This solution provides multiple sub-working positions with different distances, thereby achieving multi-level adjustment of the air pressure at the air intake 16. As an alternative implementation, the support member 2 only has a first working position extending out of the opening of the dust hood 1, and a second position where the support member 2 is removed or retracted into the dust hood 1. Figure 1 As shown, the support member 2 extends from the air intake 16 below the dust cover 1. When the air intake 16 faces and is close to the surface to be cleaned, the support member 2 contacts the surface to be cleaned before the air intake 16, thus supporting the air intake 16 at a certain height from the cleaning surface. Since the amount of air drawn in by the fan inside the vacuum cleaner per unit time is constant when the vacuum cleaner is working, when the height of the air intake 16 from the cleaning surface is low, the space between the air intake 16 and the bottom surface is small. Therefore, when the amount of air drawn into the vacuum cleaner per unit time is constant, the closer the air intake 16 is to the cleaning surface, the faster the wind speed and the greater the negative pressure formed. Conversely, the slower the wind speed, the smaller the negative pressure formed.

[0061] Based on the above embodiments, as a further limiting embodiment, such as... Figures 3-4 As shown, the support member 2 is slidably connected to the vacuum hood 1. The support member 2 extends or retracts from the vacuum hood 1 by sliding. Alternatively, the support member 2 is rotatably connected to the vacuum hood 1; the distance between the end of the support member 2 and the air intake 16 varies depending on the angle at which the vacuum hood 1 is rotated open. Another alternative embodiment allows the support member 2 to be detachably connected to the vacuum hood 1, with the vacuum hood 1 having multiple different connection points suitable for connecting the support member 2, allowing the support member 2 to be in different connection positions, meaning that the distance the support member 2 extends beyond the air intake 16 varies depending on the connection position.

[0062] Based on the above embodiments, as a further limiting embodiment, such as... Figure 4 , Figure 5 As shown, the vacuum cleaner head also includes an adjustment frame 3, which is mounted on the vacuum hood 1. The adjustment frame 3 has a limiting groove 32, and the support member 2 is slidably connected to the limiting groove 32. The support member 2 is slidably connected to the adjustment frame 3, so that the adjustment frame 3 can be directly replaced if the limiting groove 32 on the adjustment frame 3 experiences sliding wear or other damage. As an alternative implementation, the adjustment frame 3 is omitted, the limiting groove 32 is formed on the vacuum hood 1, and the support member 2 is slidably connected to the vacuum hood 1.

[0063] Based on the above embodiments, as a further limiting embodiment, such as... Figure 4 , Figure 5 As shown, the support member 2 includes: a bracket 22, slidably connected to the adjusting frame 3; and a roller 21, rotatably connected to the bracket 22, with the roller 21 located at the end of the bracket 22 away from the air intake 16. The roller 21 supports the air intake 16 at a certain distance from the cleaning surface. When the vacuum cleaner head is moved, the roller 21 can roll, thereby reducing the moving resistance of the vacuum cleaner head, improving the smoothness of vacuuming, and enhancing the user experience.

[0064] Based on the above embodiments, as a further limiting embodiment, such as... Figure 5 , Figure 6As shown, the vacuum cleaner head also includes: an adjusting wheel 31, rotatably connected to the adjusting frame 3; a support member 2, rotatably connected to the adjusting wheel 31; and the support member 2 and the adjusting wheel 31 are threaded together. The rotational motion of the adjusting wheel 31 is transmitted to the support member 2, which is slidably connected to the adjusting frame 3. Therefore, the support member 2 itself cannot rotate relative to the adjusting frame 3, thus converting the rotational motion into a sliding motion relative to the adjusting frame 3. In this embodiment, the user can control the length of the support member 2 extending beyond the suction port 16 by manually adjusting the adjusting wheel 31 from the outside of the vacuum hood 1. As an alternative implementation, the support member 2 is controlled by an automatic device such as a motor, electric motor, or push rod motor to achieve automatic extension and retraction of the support member 2, thereby automatically adjusting the distance between the suction port 16 and the cleaning surface.

[0065] Specifically, the bracket 22 is slidably connected to the adjusting frame 3. This can be understood as either a direct sliding connection to the adjusting frame 3 or an indirect relative translational movement relative to the adjusting frame 3. Figure 2 From the perspective of the angle, the adjusting wheel 31 is rotatably connected to the adjusting frame 3. The center of the adjusting wheel 31 has a downwardly extending mating hole 311. The central axis of the mating hole 311 coincides with the rotation center axis of the adjusting wheel 31. When the adjusting wheel 31 rotates, the mating hole 311 rotates coaxially with the adjusting wheel 31. The bracket 22 is sleeved in the mating hole 311, and the outer side of the bracket 22 is provided with a connecting thread 222. The inner wall of the mating hole 311 has a mating thread 312 adapted to the connecting thread 222. When the adjusting wheel 31 rotates, the bracket 22 has a tendency to rotate synchronously with the adjusting wheel 31. In this embodiment, since the bracket 22 is slidably connected in the limiting groove 32, the bracket 22 cannot rotate in the limiting groove 32. Therefore, the adjusting wheel 31 rotates alone, and relative movement occurs between the threads of the adjusting wheel 31 and the bracket 22, causing the bracket 22 to slide along the limiting groove 32.

[0066] The adjusting wheel 31 is provided with a textured structure 313, which can improve the coefficient of friction and facilitate manual adjustment by the user.

[0067] Based on the above embodiments, as a further limiting embodiment, such as... Figure 5 , Figure 6 As shown, the vacuum cleaner head also includes a positioning post 38, which is slidably connected to the adjustment frame 3 and / or the vacuum cover 1. The adjustment wheel 31 and / or the support member 2 are provided with multiple gear holes 314. When the positioning post 38 is inserted into different gear holes 314, it can limit the gear holes 314, thereby preventing the adjustment wheel 31 or the support member 2 from continuing to move. After the user adjusts the support member 2 to a suitable gear, the positioning post 38 positions the support member 2 to maintain the current height of the vacuum cleaner head.

[0068] Based on the above embodiments, as a further limiting embodiment, such as... Figure 5 As shown, the adjusting frame 3 is provided with an installation cylinder 36, and the positioning post 38 is disposed inside the installation cylinder 36. One end of the installation cylinder 36 is open, and the open end faces the adjusting wheel 31. A limiting elastic element 35 is provided between the positioning post 38 and the bottom of the installation cylinder 36. The stop hole 314 is located on the adjusting wheel 31. The limiting elastic element 35 can support the positioning post 38, keeping the positioning post 38 inserted into the stop hole 314, so that the adjusting wheel 31 cannot rotate.

[0069] Based on the above embodiments, as a further limiting embodiment, such as... Figures 4-6 As shown, the wall of the gear position hole 314 is arc-shaped and forms a guide arc surface 315 connecting the outside of the gear position hole 314. Since the positioning pin 38 is inserted into the gear position hole 314 and is supported by the limiting elastic element 35, the adjusting wheel 31 cannot break through the restriction of the positioning pin 38 and rotate without external force. In this solution, when the adjusting wheel 31 rotates under the action of external force, the end of the positioning pin 38 slides out of the gear position hole 314 along the guide arc surface 315, so that the distance of the support member 2 extending out can be adjusted under the action of external force.

[0070] Based on the above embodiments, as a further limiting embodiment, such as... Figure 4 , Figure 5 As shown, the dust cover 1 is provided with a first connecting hole 33 and a second connecting hole 12. The positioning bolt 34 passes through the first connecting hole 33 and the second connecting hole 12 in sequence and is then tightened.

[0071] Based on the above embodiments, as a further limiting embodiment, such as... Figure 4 , Figure 5 As shown, the dust cover 1 is provided with a limiting part 13, the limiting part 13 includes a limiting slot 131, and the adjusting frame 3 is provided with a snap-fit ​​part that is adapted to the limiting slot 131.

[0072] The adjustment bracket 3 is first positioned by inserting the locking part into the limiting slot 131 so that the first connecting hole 33 and the second connecting hole 12 are exactly aligned, and then the positioning bolt 34 is used to achieve a tight connection.

[0073] Based on the above embodiments, as a further limiting embodiment, such as... Figure 4 , Figure 5As shown, the dust cover 1 is provided with a limiting protrusion 14, which extends in the direction pointing towards the limiting slot 131. The limiting protrusion 14 can play a guiding role. When installing the adjustment bracket 3, the adjustment bracket 3 can be placed against the limiting protrusion 14 and slid along the limiting protrusion 14 so that the locking part is just inserted into the limiting slot 131.

[0074] Based on the above embodiments, as a further limiting embodiment, such as... Figure 5 , Figure 6 As shown, the dust cover 1 has a through hole 11, and the adjusting wheel 31 is exposed at least partially through the through hole 11. With the adjusting wheel 31 exposed, the user can control the support member 2 to extend or retract the dust cover 1 by manually rotating the adjusting wheel 31.

[0075] In this embodiment, the vacuum cleaner head is mounted on the vacuum cleaner, such as... Figure 1 As shown, a connecting rod 4 is connected to the vacuum cleaner head, and an air intake channel 15 is provided inside the connecting rod 4, which communicates with the air intake 16. The vacuum cleaner may also include other handheld structures, which will not be described in detail in this embodiment.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
