[0039] Please continue reading. Figures 1 to 7 In some embodiments, one end of the second mounting portion 192 is retractably connected to the side of the first mounting portion 191 opposite to the extension tube 15 along a first direction. That is, one end of the second mounting portion 192 can retract relative to the first mounting portion 191. For example, one end of the second mounting portion 192 may be located away from the end of the extension tube 15 relative to the first mounting portion 191; or, the second mounting portion 192 may be located closer to the end of the extension tube 15 relative to the first mounting portion 191. Herein, the first direction is the length extension direction of the extension tube 15.

[0040] The second mounting portion 192 is retractably connected at one end to the first mounting portion 191, which allows for changes in the angular relationship between the extension tube 15 and the surface to be cleaned, thereby improving the user experience. The retractable connection between the second mounting portion 192 and the first mounting portion 191 can be achieved through an elastic structure or other means, which is not limited here. One end of the second mounting portion 192 is retractably connected to either the first sub-mounting portion 1911 or the second sub-mounting portion 1912.

[0041] In some embodiments, the rolling assembly 19 includes a first elastic member 194. The first elastic member 194 has a certain elasticity. The first elastic member 194 is connected between the first sub-mounting portion 1911 and the second mounting portion 192. One end of the first elastic member 194 is detachably or fixedly connected to the first mounting portion 191. The other end of the first elastic member 194 is detachably or fixedly connected to the second mounting portion 192. The first elastic member 194 extends along a first direction. By providing the first elastic member 194 between the first sub-mounting portion 1911 and the second mounting portion 192, different angular relationships between the extension tube 15 and the surface to be cleaned can be satisfied, thereby facilitating user operation. When the extension tube 15 is released from contact with the surface to be cleaned, the second mounting portion 192 can automatically return to its original state under the action of the first elastic member 194, thereby improving the user experience.

[0042] When the first elastic member 194 is connected between the first sub-mounting portion 1911 and the second mounting portion 192, the first sub-mounting portion 1911 and the second mounting portion 192 may also be provided with other structures to improve the stability of the telescopic connection between the first sub-mounting portion 1911 and the second mounting portion 192. For example, a sliding structure or a moving structure may be provided between the first sub-mounting portion 1911 and the second mounting portion 192. The first elastic member 194 may be, but is not limited to, a compression spring.

[0043] In some embodiments, a pivot mounting portion 19113 is provided on the outer periphery of the first mounting portion 191. The pivot mounting portion 19113 is detachably or fixedly connected to the outer periphery of the first mounting portion 191. In this embodiment, the pivot mounting portion 19113 is integrally formed on the outer periphery of the first mounting portion 191. The rolling assembly 19 includes a rolling shaft 195. The rolling shaft 195 passes through the pivot mounting portion 19113 and slides on the second mounting portion 192. The pivot mounting portion 19113 is connected to the second mounting portion 192 via the rolling shaft 195. The rolling shaft 195 not only slides along a first direction on the second mounting portion 192, reducing movement offset, but also acts as a pivot, allowing the second mounting portion 192 to rotate relative to the first mounting portion 191 by a certain angle. A first elastic member 194 is connected between the rolling shaft 195 and the second mounting portion 192. One end of the first elastic member 194 is detachably or fixedly connected to the rolling shaft 195. One end of the first elastic element 194 can be detachably or fixedly connected to the second mounting part 192.

[0044] By working together with the aforementioned rotating shaft mounting part 19113, rolling shaft 195, second mounting part 192 and first elastic member 194, not only is the stability of the second mounting part 192 being telescopically connected to the first mounting part 191 improved, but the second mounting part 192 can also rotate relative to the first mounting part 191 at a certain angle. At the same time, the structure is simple and easy to install and operate, thereby meeting the usage and operation needs of different users.

[0045] In some specific embodiments, sliding holes 1921 are provided at both ends of the second mounting portion 192. The sliding holes 1921 extend along a first direction, that is, they extend along the length extension direction of the extension tube 15. The ends of the rolling shaft 195 are respectively located in the corresponding sliding holes 1921. Specifically, one end of the rolling shaft 195 is located in the sliding hole 1921 at one end of the second mounting portion 192, and the other end of the rolling shaft 195 is located in the sliding hole 1921 at the other end of the second mounting portion 192. In addition, the rolling shaft 195 can also rotate relative to the sliding holes 1921.

[0046] The combined action of the rolling shaft 195 and the sliding hole 1921 not only defines the direction of movement of the rolling shaft 195, allowing the second mounting portion 192 to extend and retract relative to the first mounting portion 191, but also provides a movement trajectory, reducing the risk of movement deviation of the rolling shaft 195 and the first elastic element 194, thereby improving the smoothness of the extension and retraction movement. The sliding hole 1921 can be, but is not limited to, an oblong hole or a rectangular hole.

[0047] In some embodiments, the rolling assembly 19 includes a second elastic member 196. The second elastic member 196 is sleeved on the rolling shaft 195. One end of the second elastic member 196 abuts against the outer periphery of the first sub-mounting portion 1911. The other end of the second elastic member 196 abuts against the interior of the second mounting portion 192. When the rolling shaft 195 acts as a pivot, the second mounting portion 192 can rotate relative to the first mounting portion 191 by a certain angle via the rolling shaft 195, further changing the angle between the rolling member 193 and the surface to be cleaned. Furthermore, when the extension tube 15 is released from contact with the surface to be cleaned, the second mounting portion 192 can automatically return to its original shape under the action of the second elastic member 196, thereby improving the user experience. The second elastic member 196 may be, but is not limited to, a torsion spring.

The extension tube 15 is detachably connected to the vacuum cleaner body 11. The extension tube 15 can be connected to the vacuum cleaner body 11 by means of, but not limited to, snap-fit, plug-in, and bolts. In this embodiment, the extension tube 15 is snap-fitted to the vacuum cleaner body 11, thereby improving the efficiency of disassembling the extension tube 15. The rolling assembly 19 is detachably connected to the outer periphery of one end of the extension tube 15. The first mounting portion 191 of the rolling assembly 19 is detachably connected to the outer periphery of one end of the extension tube 15. Through the aforementioned rolling assembly 19, the vacuum cleaner 10 not only facilitates the user's operation and movement of the extension tube 15 but also reduces movement resistance, thereby improving the user experience. It should be noted that the rolling assembly 19 in this embodiment is the same as the rolling assembly 19 described in the above embodiments, and will not be repeated here.

[0049] In some embodiments, a flexible layer (not shown in the figure) is provided on the outer periphery of the end of the extension tube 15 near the rolling assembly 19. When the extension tube 15 cleans the surface to be cleaned, the flexible layer on the end of the extension tube 15 contacts the surface to be cleaned, which can protect the surface to be cleaned and reduce the risk of damage to the end of the extension tube 15. The aforementioned flexible layer can be, but is not limited to, rigid plastics and flexible plastics.

[0050] In some embodiments, the top of the side of the vacuum cleaner body 11 facing away from the floor brush assembly 12 is provided with an abutment slope 118. The abutment slope 118 is inclined downward from the vacuum cleaner body 11. The abutment slope 118 can provide a certain clearance position for the rolling assembly 19 on the extension tube 15, thereby reducing the resistance of the extension tube 15 when installed on the vacuum cleaner body 11.

[0051] The rolling component 19 on the extension tube 15 can roll on the abutting inclined surface 118. When the extension tube 15 is continued to be installed in the vacuum cleaner body 11, the second mounting part 192 in the rolling component 19 can rotate at a certain angle relative to the first mounting part 191, so that the rolling element 193 on the second mounting part 192 abuts against the outer peripheral side of the vacuum cleaner body 11, thereby facilitating the continued installation of the extension tube 15 into the vacuum cleaner body 11, thereby improving the user experience.

[0052] Please see Figure 9 , Figure 10 as well as Figure 11 , Figure 9 This is a first structural schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 10 This is an exploded view of an embodiment of the vacuum cleaner of this application; Figure 11 This is a second structural schematic diagram of an embodiment of the vacuum cleaner of this application. (In conjunction with...) Figures 1 to 8 In some embodiments, the vacuum cleaner 10 includes a floor brush assembly 12, a power assembly 14, a dust cup assembly 16, a handle assembly 17, and a hose 13. The rear end of the floor brush assembly 12 is connected to the front of the vacuum cleaner body 11. That is, the floor brush assembly 12 is located at the front of the vacuum cleaner body 11.

[0053] The power unit 14 is detachably connected to the front of the vacuum cleaner body 11. The dust cup assembly 16 is detachably connected to the front of the vacuum cleaner body 11. The handle assembly 17 is used for handheld operation, thereby improving the user experience. One end of the handle assembly 17 is detachably connected to the extension tube 15. The other end of the handle assembly 17 is detachably connected to the hose 13. The other end of the hose 13 is detachably connected to the dust cup assembly 16. The dust cup assembly 16 is detachably connected to the upper part of the power unit 14.

[0054] When the vacuum cleaner 10 cleans the surface to be cleaned, the airflow carrying debris enters from the floor brush assembly 12 and passes sequentially through the extension tube 15, the hose 13, and the dust cup assembly 16. The dust cup assembly 16 then filters the debris-laden airflow, storing the debris within. Finally, the filtered airflow enters the power assembly 14 and is discharged. During the operation of the vacuum cleaner 10, under the suction action of the power assembly 14, the airflow flows sequentially along the floor brush assembly 12, the vacuum cleaner body 11, the extension tube 15, the handle assembly 17, the hose 13, the dust cup assembly 16, and the power assembly 14. Through the combined action of the floor brush assembly 12, the vacuum cleaner body 11, the extension tube 15, the handle assembly 17, the hose 13, the dust cup assembly 16, and the power assembly 14, the surface to be cleaned is effectively cleaned.

[0055] In some embodiments, the dust cup assembly 16 is detachably connected to and communicates with the power assembly 14. The filtered airflow from the dust cup assembly 16 flows into the power assembly 14 and is then discharged. This arrangement facilitates the removal and handling of the dust cup assembly 16, making it easier for the user to empty any debris from it.

[0056] Please see Figure 12 and Figure 13 , Figure 12 This is a second partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 13 This is a partial schematic diagram of a third embodiment of the vacuum cleaner of this application. (In conjunction with...) Figures 1 to 11 In some embodiments, the upper end of the floor brush connector 122 is detachably connected to the first end of the vacuum cleaner body 11. There are at least two states between the floor brush assembly 12 and the vacuum cleaner body 11.

[0057] The extension tube 15 can be releasably locked to the rear of the second end of the vacuum cleaner body 11. That is, there are at least two possible states between the extension tube 15 and the second end of the vacuum cleaner body 11. For example... Figure 9 As shown, when the floor brush assembly 12 cleans the surface to be cleaned, the extension tube 15 can be locked at the second end, and the airflow flows sequentially along the floor brush assembly 12, the vacuum cleaner body 11, the extension tube 15, the handle assembly 17, the hose 13, the dust cup assembly 16, and the power assembly 14. Figure 12 As shown, when the extension tube 15 is cleaning the surface to be cleaned, the extension tube 15 is de-locked from the second end, and airflow flows sequentially from the extension tube 15, handle assembly 17, hose 13, dust cup assembly 16, and power assembly 14. The floor brush assembly 12 is connected to the first end; alternatively, the floor brush assembly 12 can be de-connected to the first end, which is not limited here. De-connecting the floor brush assembly 12 to the first end when the extension tube 15 is cleaning the surface not only reduces the weight of the vacuum cleaner 10 but also lowers the operating height, increasing its applicability.

[0058] One end of the handle assembly 17 is detachably connected to one end of the extension tube 15. That is, there can be at least two states between one end of the handle assembly 17 and one end of the extension tube 15. For example... Figure 13 As shown, when one end of the handle assembly 17 is cleaning the surface to be cleaned, the airflow flows sequentially along the handle assembly 17, the hose 13, the dust cup assembly 16, and the power assembly 14. The floor brush assembly 12 is connected to the first end; alternatively, the floor brush assembly 12 can be disconnected from the first end, which is not limited here. When the handle assembly 17 is cleaning the surface to be cleaned, the floor brush assembly 12 is disconnected from the first end, which not only reduces the weight of the vacuum cleaner 10 but also lowers the operating height and increases its applicability.

[0059] The detachable connection between the upper end of the floor brush connector 122 and the first end of the vacuum cleaner body 11, the detachable connection between one end of the handle assembly 17 and one end of the extension tube 15, and / or the detachable connection between one end of the handle assembly 17 and one end of the extension tube 15, together increase the number of usage modes of the vacuum cleaner 10 and improve the user experience.
