[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0059] The vacuum cleaner provided by this utility model will be described in detail below with reference to the embodiments.

[0060] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 This is a first structural schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 2 This is a first partial cross-sectional schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 3 This is a schematic diagram of the structure of the floor brush assembly 12 in the vacuum cleaner of this application; Figure 4 This is a second structural schematic diagram of an embodiment of the vacuum cleaner of this application. This application provides a vacuum cleaner. The vacuum cleaner 10 uses negative pressure to suck up dust, dirt, etc. The vacuum cleaner 10 includes a vacuum cleaner body 11, a floor brush assembly 12, an extension tube 15, a dust cup assembly 16, and a power assembly 14, etc. The vacuum cleaner body 11 provides mounting positions for the floor brush assembly 12, the extension tube 15, the dust cup assembly 16, and the power assembly 14, etc. The floor brush assembly 12 is used to remove dust and dirt from the surface to be cleaned (not shown in the figure). The specific structure and working principle of the aforementioned floor brush assembly 12 are conventionally known to those skilled in the art and will not be described in detail here.

[0061] The vacuum cleaner body 11 includes a first end (not shown in the figure) and a second end (not shown in the figure) that are arranged opposite to each other. The first end and the second end can be, but are not limited to, vertically opposite each other; for example, the first end of the vacuum cleaner body 11 can be the lower end of the vacuum cleaner body 11, and the second end of the vacuum cleaner body 11 can be the upper end of the vacuum cleaner body 11. The floor brush assembly 12 includes a floor brush body 121 and a floor brush connector 122. The lower end of the floor brush connector 122 is rotatably connected to the rear of the floor brush body 121, meaning the floor brush connector 122 can rotate a certain angle relative to the rear of the floor brush body 121, with the floor brush body 121 located at the front of the floor brush connector 122. The rotating structure can be, but is not limited to, a pivot, hinge, etc. The upper end of the floor brush connector 122 is connected to the first end. The floor brush connector 122 can be detachably connected to or fixedly connected to the first end. When the floor brush connector 122 rotates at a certain angle relative to the floor brush body 121, the vacuum cleaner body 11 also moves with the floor brush connector 122, thereby changing the angle between the vacuum cleaner body 11 and the surface to be cleaned, thus meeting the user's cleaning needs at different angles.

[0062] The aforementioned floor brush connector 122 extends along a first axis. This first axis can be, but is not limited to, a first direction, which can be vertical. When the vacuum cleaner 10 is in an upright position, the first axis can be, but is not limited to, a vertical direction. An extension tube 15 is releasably locked to the rear of the second end of the vacuum cleaner body 11. The extension tube 15 can be locked to the rear of the second end of the vacuum cleaner body 11; or, the extension tube 15 can be released from the rear of the second end of the vacuum cleaner body 11. The extension tube 15 and the rear of the second end of the vacuum cleaner body 11 can be connected, but is not limited to, via a locking assembly or the like. The aforementioned extension tube 15 extends along a second axis. This second axis can be, but is not limited to, a second direction, which can be vertical or the like.

[0063] The dust cup assembly 16 and the power assembly 14 are disposed on the outer periphery of the vacuum cleaner body 11. The dust cup assembly 16 is detachably or fixedly connected to the outer periphery of the vacuum cleaner body 11. The power assembly 14 is detachably or fixedly connected to the outer periphery of the vacuum cleaner body 11. The dust cup assembly 16 separates the airflow carrying debris, which is stored within the dust cup assembly 16, while the airflow enters the power assembly 14 through the air inlet 14111. The power drive component 142 has a certain suction force for airflow.

[0064] When the vacuum cleaner 10 is in an upright position, the second axis and the first axis are parallel to each other. That is, the floor brush connector 122 extends along the first axis and is disposed at the first end of the vacuum cleaner body 11, and the extension tube 15 extends along the second axis and is disposed at the second end of the vacuum cleaner body 11. The floor brush connector 122 and the extension tube 15 are not coaxially arranged. When the dust cup assembly 16 and the power assembly 14 are disposed on the outer periphery of the vacuum cleaner body 11, the above arrangement can change the center of gravity of the vacuum cleaner 10. When the vacuum cleaner 10 is in an upright position, the structure of the vacuum cleaner 10 is more stable and less likely to tip over, thereby improving the user experience.

[0065] The aforementioned second axis and first axis can be arranged front to back, for example, the second axis may be located in front of the first axis; or, the second axis may be located behind the first axis. Alternatively, the second axis and first axis can be arranged side to side, for example, the second axis may be located to the left of the first axis; or, the second axis may be located to the right of the first axis, etc. When the position between the second axis and the first axis changes, the positions of the extension tube 15, the floor brush assembly 12, the dust cup assembly 16, and the power assembly 14 in the vacuum cleaner 10 can change accordingly, as long as the center of gravity remains stable, and no limitation is imposed here.

[0066] In one specific embodiment, both the dust cup assembly 16 and the power assembly 14 are 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 power assembly 14 is detachably connected to the front of the vacuum cleaner body 11. The rear end of the floor brush assembly 12 is connected to the front of the vacuum cleaner body 11, meaning the floor brush assembly 12 is located at the front of the vacuum cleaner body 11. The extension tube 15 is connected to the rear of the vacuum cleaner body 11. By positioning and arranging the dust cup assembly 16, power assembly 14, floor brush assembly 12, and extension tube 15 on the vacuum cleaner body 11, the second axis is positioned in front of the first axis. When the vacuum cleaner 10 is in an upright state, the center of gravity of the vacuum cleaner 10 is further forward, closer to the center of gravity of the floor brush assembly 12 support point, making the vacuum cleaner 10 more stable and less prone to tipping over, thereby improving the user experience.

[0067] In some embodiments, a transition portion 117 is provided inside the vacuum cleaner body 11. The transition portion 117 serves as a transition. The vacuum cleaner body 11 is provided with a first main airflow channel 115 and a second main airflow channel 116. The first main airflow channel 115 extends along a first axis. The second main airflow channel 116 extends along a second axis. The first main airflow channel 115 and the second main airflow channel 116 are respectively connected to the transition portion 117. The floor brush connector 122 is at least partially connected to the first main airflow channel 115. The extension tube 15 is at least partially connected to the second main airflow channel 116.

[0068] By altering the internal structure of the vacuum cleaner body 11, the second axis of the extension tube 15 is positioned in front of the first axis of the floor brush connector 122. When the vacuum cleaner 10 is in an upright position, its center of gravity is shifted further forward, closer to the center of gravity of the floor brush assembly 12 support point. This makes the vacuum cleaner 10 more stable and less prone to tipping over, thereby improving the user experience. The aforementioned first main body airflow channel 115, second main body airflow channel 116, and transition section 117 can be integrally formed.

[0069] Please see Figure 5 as well as Figure 6 , Figure 5 This is an exploded view of an embodiment of the vacuum cleaner of this application; Figure 6 This is a third structural schematic diagram of an embodiment of the vacuum cleaner of this application. (In conjunction with...) Figures 1 to 4 In some embodiments, the vacuum cleaner 10 includes a handle assembly 17 and a hose 13. The handle assembly 17 is used for handheld operation by the user, thereby improving the user experience. One end of the handle assembly 17 is connected to an extension tube 15. The end of the handle assembly 17 and the end of the extension tube 15 facing away from the vacuum cleaner body 11 are detachably or fixedly connected. The other end of the handle assembly 17 is connected to the hose 13. The other end of the handle assembly 17 and the hose 13 are detachably or fixedly connected. The other end of the hose 13 is connected to a dust cup assembly 16. The other end of the hose 13 is detachably or fixedly connected to the dust cup assembly 16. The dust cup assembly 16 is connected to the upper end of the power assembly 14. The dust cup assembly 16 is detachably or fixedly connected to the power assembly 14.

[0070] 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.

[0071] In some embodiments, the dust cup assembly 16 is detachably connected to and communicates with the power assembly 14. The dust cup assembly 16 is detachably connected to the power assembly 14. The dust cup assembly 16 can be connected to the power assembly 14 by, but is not limited to, snap-fit, plug-in, or bolt methods. The dust cup assembly 16 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 of the dust cup assembly 16 and makes it easier for the user to empty any debris from it.

[0072] Please see Figure 7 and Figure 8 , Figure 7 This is a first partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 8 This is a second partial schematic diagram of an embodiment of the vacuum cleaner of this application. (In conjunction with...) Figures 1 to 6 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. This means the upper end of the floor brush connector 122 is connected to the first end; or the upper end of the floor brush connector 122 is disconnected from the first end, i.e., there are at least two states between the floor brush assembly 12 and the vacuum cleaner body 11. The detachable connection can be, but is not limited to, snap-fit ​​and plug-in connections. Furthermore, the upper end of the floor brush connector 122 can be electrically connected to the first end of the vacuum cleaner body 11.

[0073] 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. When the floor brush assembly 12 is cleaning the surface to be cleaned, the extension tube 15 can be locked to 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. When the extension tube 15 is cleaning the surface to be cleaned, the extension tube 15 is released from the second end, and the airflow flows sequentially from the extension tube 15, 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 extension tube 15 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 the applicable range.

[0074] One end of the handle assembly 17 is detachably connected to one end of the extension tube 15. That is, there are at least two possible states between the handle assembly 17 and the extension tube 15. When the floor brush assembly 12 is cleaning the surface to be cleaned, one end of the handle assembly 17 is connected to one end of the extension tube 15, 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 component 14. When the extension tube 15 is cleaning the surface to be cleaned, one end of the handle assembly 17 is connected to one end of the extension tube 15, and the airflow flows sequentially from the extension tube 15, the handle assembly 17, the hose 13, the dust cup assembly 16, and the power component 14. 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 component 14. The floor brush assembly 12 is connected to the first end; alternatively, the floor brush assembly 12 can be detached from the first end, which is not limited here. When the handle assembly 17 cleans 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 the applicable range.

[0075] 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.

[0076] In some embodiments, the vacuum cleaner 10 includes at least one first accessory mounting portion 113.

[0098] Please continue reading. Figures 12 to 18 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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. 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] Please see Figure 19 , Figure 20 , Figure 21 as well as Figure 22 , Figure 19 This is a fourth partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 20 yes Figure 19 The structural diagram of B shown below; Figure 21 This is a second partial cross-sectional schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 22This is a third partial cross-sectional schematic diagram of an embodiment of the vacuum cleaner of this application. The vacuum cleaner 10 includes a locking assembly 153. The vacuum cleaner body 11 is provided with a mating surface 111. The mating surface 111 is used to install an extension tube 15. The extension tube 15 extends along a first direction. The extension tube 15 is provided with a locking seat 152. The locking seat 152 is used to install the locking assembly 153. The locking assembly 153 is provided in the locking seat 152. The locking assembly 153 is detachably or fixedly connected to the locking seat 152. The locking assembly 153 can release the mating surface 111. When the locking assembly 153 is locked to the mating surface 111, the extension tube 15 can be locked to the vacuum cleaner body 11. When the locking assembly 153 is released from the mating surface 111, the extension tube 15 can be released from the vacuum cleaner body 11.

[0108] The aforementioned locking assembly 153 includes a locking button seat 1531. An external force drives the locking button seat 1531, enabling the locking assembly 153 to release the locking mating surface 111. For example, under an upward force in the first direction, the locking assembly 153 releases from the mating surface 111, and the extension tube 15 moves upward along the first direction with the locking seat 152. That is, the upward movement of the locking button seat 1531 in the first direction is the same as the upward movement of the extension tube 15 in the first direction.

[0109] Therefore, through the cooperation of the mating surface 111 of the vacuum cleaner body 11, the locking seat 152 on the extension tube 15, and the locking button seat 1531 in the locking assembly 153, the direction in which the user triggers the locking button seat 1531 is consistent with the direction in which the extension tube 15 is disassembled, facilitating user operation and improving the user experience. The locking assembly 153 can be locked to the mating surface 111 by means of snap-fit, plug-in, etc. Furthermore, the locking assembly 153 can be, but is not limited to, snap-fit ​​components, plug-in components, etc., which are not limited here.

Figures 19 to 22In some embodiments, the locking assembly 153 includes a locking button 1532. At least a portion of the locking button 1532 is disposed at the lower end of the locking button base 1531. At least a portion of the locking button 1532 is detachably or fixedly connected to the lower end of the locking button base 1531. At least a portion of the locking button 1532 is bolted to the lower end of the locking button base 1531. At least another portion of the locking button 1532 extends beyond the outer surface of the locking base 152 to indicate its function to the user. The locking button 1532 and the locking button base 1531 in the locking assembly 153 cooperate to facilitate the user indirectly driving the locking button base 1531 upward in a first direction via the locking button 1532, and also serve as a prompt, thereby facilitating the indication of its function to the user.

[0111] Specifically, the locking button 1532 includes a first locking button 15321 and a second locking button 15322. One end of the first locking button 15321 is connected to the lower end of the locking button base 1531. The first locking button 15321 is detachably or fixedly connected to the lower end of the locking button base 1531. The other end of the first locking button 15321 is bolted to the lower end of the locking button base 1531. The other end of the first locking button 15321 is connected to the second locking button 15322. The other end of the first locking button 15321 is detachably or fixedly connected to the second locking button 15322. The first locking button 15321 and the second locking button 15322 are integrally formed. The second locking button 15322 extends upward along a first direction, which not only increases the area of ​​the locking button 1532 extending beyond the outer surface of the locking base 152, but also makes it easier for the user to understand its function.

[0112] Furthermore, the aforementioned second locking button 15322 may include one of the following: a colorless transparent second locking button, a colored second locking button, or a text-labeled second locking button. If the second locking button 15322 is a colorless transparent second locking button, the user can identify the locking function through its transparency. Alternatively, if the second locking button 15322 is a colored second locking button, the color of the colored second locking button differs from other components, allowing the user to identify the locking function through its color. Alternatively, if the second locking button 15322 is a text-labeled second locking button, the text and / or graphics are embedded or raised, thereby indicating to the user that the text and / or graphics indicate the locking function. The aforementioned second locking button 15322 may also include other second locking buttons that serve a functional indication purpose. Of course, the function of the first locking button 15321 may also be the same as the function of the second locking button 15322, and will not be elaborated further here.

[0113] In some embodiments, the locking assembly 153 includes a latch 1533 and a first locking elastic member 1534. The latch 1533 is releasably locked to the mating surface 111. Specifically, the latch 1533 is locked to the mating surface 111; or, the latch 1533 is released from the mating surface 111. A locking button seat 1531 is connected to the latch 1533. The locking button seat 1531 is used to drive the latch 1533 to release from the mating surface 111, allowing the extension tube 15 to move upward in a first direction. One end of the first locking elastic member 1534 is connected to the locking seat 152. Specifically, one end of the first locking elastic member 1534 is detachably or fixedly connected to the locking seat 152. The other end of the first locking elastic member 1534 is connected to the end of the latch 1533 facing away from the mating surface 111. The first locking elastic element 1534 has its other end detachably or fixedly connected to the end of the latch 1533 facing away from the mating surface 111. The first locking elastic element 1534 is used to drive the other end of the latch 1533 to lock with the mating surface 111. When the extension tube 15 is installed downward along the first direction on the mating surface 111, the latch 1533 is locked to the mating surface 111 under the action of the first locking elastic element 1534, so that the extension tube 15 is installed on the vacuum cleaner body 11.

[0114] Through the combined action of the aforementioned latch 1533, first locking elastic element 1534, locking seat 152, and mating surface 111, not only is a releaseable locking mechanism achieved between the latch 1533 and the mating surface 111, but the structure is also simple, easy to install, and easy to operate. The aforementioned first locking elastic element 1534 may be, but is not limited to, a locking spring.

[0115] Please see Figure 24 and Figure 25 , Figure 24 This is a fifth partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 25 yes Figure 24 The diagram shows the structure of C. (Combined with...) Figures 19 to 23 In some embodiments, the mating surface 111 is provided with a locking groove 1111. The latch 1533 is releasably locked in the locking groove 1111. The top of the locking button base 1531 is provided with a first driving surface 15311. The latch 1533 is provided with a second driving surface 15331. The first driving surface 15311 and the second driving surface 15331 mate. Both the first driving surface 15311 and the second driving surface 15331 extend downwards away from the locking groove 1111. Through the combined action of the first driving surface 15311 of the locking button base 1531 and the second driving surface 15331 of the latch 1533, the smoothness of the locking button base 1531 driving the latch 1533 is improved, thereby reducing movement resistance and enhancing the user experience.

[0116] In some embodiments, the locking assembly 153 further includes a latch fixing seat 1535. The latch fixing seat 1535 is disposed within the locking seat 152. The latch fixing seat 1535 may be confined within the locking seat 152. One end of a first locking elastic member 1534 is disposed within the latch fixing seat 1535. One end of the first locking elastic member 1534 abuts against the latch fixing seat 1535. The other end of the first locking elastic member 1534 is connected to one end of a latch 1533. The other end of the first locking elastic member 1534 abuts against one end of the latch 1533. The other end of the latch 1533 at least partially extends beyond the latch fixing seat 1535.

[0117] By placing both the first locking elastic element 1534 and the latch 1533 within the latch fixing seat 1535, the movement direction of the first locking elastic element 1534 and the latch 1533 can be limited, reducing the risk of movement deviation of the first locking elastic element 1534 and the latch 1533, thereby improving the accuracy of the latch 1533 locking in the locking groove 1111, and thus improving the accuracy and stability of the extension tube 15 installed on the vacuum cleaner body 11.

[0118] In some embodiments, the locking assembly 153 further includes a second locking elastic member 1536. The second locking elastic member 1536 has a certain elasticity. One end of the second locking elastic member 1536 is disposed at the end of the locking button seat 1531 near the latch fixing seat 1535. The other end of the second locking elastic member 1536 is disposed at the end of the latch fixing seat 1535 facing the locking button seat 1531. The second locking elastic member 1536 is detachably or fixedly connected between the locking button seat 1531 and the latch fixing seat 1535.

[0119] When the second locking button seat 151 drives the latch 1533 to move, the locking button seat 1531 can return to its original shape under the restoring force of the second locking elastic member 1536, thereby improving the user experience. The aforementioned second locking elastic member 1536 may be, but is not limited to, a second locking compression spring, etc.

[0120] In some embodiments, the locking assembly 153 further includes a latch fixing seat 1535. A latch extension 15351 is provided at the bottom of the latch fixing seat 1535. The latch extension 15351 is detachably or fixedly connected to the latch fixing seat 1535. The latch extension 15351 is integrally formed on the bottom of the latch fixing seat 1535. The locking button seat 1531 is provided with a button extension 15312. The button extension 15312 is detachably or fixedly connected to the locking button seat 1531. The button extension 15312 is integrally formed on the locking button seat 1531. The button extension 15312 is located within the latch extension 15351.

[0121] By cooperating with the button extension 15312 and the latch extension 15351, the button extension 15312 moves along the inside of the latch extension 15351, which reduces the risk of the locking button seat 1531 deviating upward in the first direction, thereby improving the stability of the connection between the latch 1533 and the locking groove 1111. The first driving surface 15311 is located at the top of the button extension 15312; the second driving surface 15331 is located at the lower end of the latch extension 15351.

[0122] The aforementioned locking seat 152 may be provided with a locking component 153, wherein the locking component 153 is releasably locked to one side of the mating surface 111; or, the locking component 153 is releasably locked to the other side of the mating surface 111. When the mating surface 111 is located at the rear of the vacuum cleaner body 11, the locking component 153 is releasably locked to the left side of the mating surface 111. Alternatively, when two locking components 153 are provided in the locking seat 152, the two locking components 153 can be arranged side by side, one locking component 153 is releasably locked to one side of the mating surface 111, and the other locking component 153 is releasably locked to the other side of the mating surface 111. When the user simultaneously applies upward along the first direction to both locking button seats 1531, one locking component 153 is released from locking to one side of the mating surface 111, and the other locking component 153 is released from locking to the other side of the mating surface 111. At this time, the extension tube 15 moves upward along the first direction with the locking seat 152.

[0123] In some embodiments, a locking and limiting component (not shown in the figure) is provided between the top of the vacuum cleaner body 11 near the mating surface 111 and the outer periphery of the locking seat 152. The locking and limiting component includes a locking and limiting part 1525 and a locking and limiting groove 112. The locking and limiting part 1525 and the locking and limiting groove 112 cooperate to achieve a pre-positioning function, thereby improving the accuracy of the locking component 153 locking onto the mating surface 111, thus improving the accuracy of the extension tube 15 being installed on the vacuum cleaner body 11 and improving the user experience. An opening groove (not shown in the figure) is formed at the upper end of the locking and limiting groove 112, and the locking and limiting part 1525 is inserted into the locking and limiting groove 112 through the opening groove. Both the locking and limiting part 1525 and the locking and limiting groove 112 extend along a first direction.

[0124] The aforementioned locking and limiting portion 1525 and locking and limiting groove 112 can be disposed on either the top of the vacuum cleaner body 11 near the mating surface 111 or the outer periphery of the locking seat 152. The locking and limiting groove 112 is disposed on the top of the vacuum cleaner body 11 near the mating surface 111. The locking and limiting portion 1525 is disposed on the outer periphery of the locking seat 152. The locking and limiting portion 1525 is detachably or fixedly connected to the outer periphery of the locking seat 152. The locking and limiting portion 1525 is integrally formed on the outer periphery of the locking seat 152. The aforementioned locking and limiting portion 1525 is inserted into the locking and limiting groove 112.

[0125] In another embodiment, a locking and limiting portion 1525 is provided on the top of the vacuum cleaner body 11 near the mating surface 111. The locking and limiting portion 1525 is detachably or fixedly connected to the top of the vacuum cleaner body 11 near the mating surface 111. The locking and limiting portion 1525 is integrally formed on the top of the vacuum cleaner body 11. A locking and limiting groove 112 is provided on the outer periphery of the locking seat 152. The aforementioned locking and limiting portion 1525 is inserted into the locking and limiting groove 112.

[0126] Please see Figure 26 and Figure 27 , Figure 26 This is a schematic diagram of the second structure of the extension tube in the vacuum cleaner of this application; Figure 27 yes Figure 26 The diagram shows the structure of D. In some embodiments, a locking extension 1524 extends from the top of the locking seat 152. The locking extension 1524 is detachably or fixedly connected to the locking seat 152. The locking extension 1524 is integrally formed into the locking seat 152. The locking extension 1524 can cover the top of the vacuum cleaner body 11. When the extension tube 15 is locked to the mating surface 111 of the vacuum cleaner body 11, the locking extension 1524 covers the top of the vacuum cleaner body 11. When the extension tube 15 is unlocked from the mating surface 111 of the vacuum cleaner body 11, the locking extension 1524 moves with the extension tube 15, at which time the locking extension 1524 disengages from the top of the vacuum cleaner body 11.

[0127] By providing the aforementioned locking extension 1524 at the top of the locking seat 152, it can not only serve as a positioning and support function, but also as a shielding function, reducing the entry of dust and other particles into the gap between the locking seat 152 and the extension tube 15, while also improving aesthetics.

[0128] In some embodiments, the locking seat 152 includes a first locking seat 1521 and a second locking seat 1522. The first locking seat 1521 and the second locking seat 1522 are detachably connected. The detachable connection method can be, but is not limited to, snap-fit, plug-in, and bolt. When the first locking seat 1521 and the second locking seat 1522 are detachably connected, a locking cavity 1523 is formed between the first locking seat 1521 and the second locking seat 1522. The aforementioned latch fixing seat 1535, locking button 1532, locking button seat 1531, latch 1533, and first locking elastic element 1534 are all located within the locking cavity 1523. The first locking seat 1521 and the second locking seat 1522 are both sleeved and connected to the outer periphery of the extension tube 15. The first locking seat 1521 and the second locking seat 1522 are detachably or fixedly connected to the outer periphery of the extension tube 15. The locking cavity 1523 is formed by the cooperation of the first locking seat 1521 and the second locking seat 1522, which not only provides an installation position for the locking assembly 153, but also improves the aesthetics and reduces the entry of dust into the locking assembly 153.

[0129] The first locking seat 1521 can be located above the second locking seat 1522; or, the first locking seat 1521 can be located below the second locking seat 1522, etc. The first locking seat 1521 and the second locking seat 1522 are connected to the outer periphery of the middle portion of the extension tube 15. The extension tube 15 can be made of metal or alloy. The first locking seat 1521 and the second locking seat 1522 can be made of plastic.

[0130] Please see Figure 28 , Figure 28 yes Figure 6 The diagram shows the structure of E. (Combined with...) Figures 19 to 27 In some embodiments, both the dust cup assembly 16 and the power assembly 14 are located at the front of the vacuum cleaner body 11. The mating surface 111 is located at the rear of the vacuum cleaner body 11. When the extension tube 15 is installed on the mating surface 111, the extension tube 15 is located at the rear of the vacuum cleaner body 11. Through the combined action of the dust cup assembly 16, the power assembly 14, and the mating surface 111, the dust cup assembly 16, the power assembly 14, and the extension tube 15 are positioned at different locations at the front and rear of the vacuum cleaner body 11, thereby reducing the overall horizontal dimensions of the vacuum cleaner 10 and making the structure of the vacuum cleaner 10 more compact.

[0131] The dust cup assembly 16 is detachably connected to the power assembly 14. The dust cup assembly 16 can be connected to the power assembly 14 by means of, but not limited to, snap-fit, plug-in, or bolts. Furthermore, the dust cup assembly 16 can be located above the power assembly 14.

[0132] Please read back Figures 19 to 25In some embodiments, the mating surface 111 is formed as an inwardly concave arc-shaped surface (not shown in the figure). This arc-shaped surface not only reduces the overall horizontal dimensions of the vacuum cleaner 10, making it more convenient to use, but also ensures reliable contact between the extension tube 15 and the vacuum cleaner body 11, while simultaneously enhancing the overall aesthetics of the vacuum cleaner 10. Furthermore, the arc-shaped surface provides excellent guidance, facilitating the disassembly of the extension tube 15.

[0133] Please see Figure 29 , Figure 30 as well as Figure 31 , Figure 29 This is a sixth partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 30 yes Figure 2 The diagram shows the structure of F. Figure 31 This is a partial schematic diagram of the power component in the vacuum cleaner of this application. (Combined with...) Figure 1 and Figure 2 The power assembly 14 includes a power shroud 141 and a power drive component 142. The power shroud 141 forms a power cavity 1413. The power cavity 1413 has an air inlet 14111 and an air outlet 14121 that communicate with each other. The power cavity 1413 provides mounting space and a mounting position for the power drive component 142. The air inlet 14111 and the air outlet 14121 are interconnected. The air inlet 14111 is the air intake position of the power assembly 14. The air inlet 14111 communicates with a dust cup assembly 16. The dust cup assembly 16 separates airflow carrying debris, where debris is stored, and airflow enters the power assembly 14 through the air inlet 14111. The air outlet 14121 is the air outlet position of the power assembly 14 for discharging air. A power drive component 142 is disposed within a power chamber 1413. The power drive component 142 is detachably connected to the power chamber 1413. The power drive component 142 generates a certain suction force to produce airflow from the air inlet 14111 to the air outlet 14121. The power drive component 142 may be, but is not limited to, a suction fan (not shown in the figure), etc.

[0134] The aforementioned power assembly 14 also includes a noise reduction cover 144 and a filter element 146. The noise reduction cover 144 is disposed on the upper end of the power cover 141. The noise reduction cover 144 is detachably or fixedly connected to the upper end of the power cover 141. The noise reduction cover 144 is connected to the upper end of the power cover 141 by bolts or other means. When the noise reduction cover 144 is disposed on the upper end of the power cover 141, a noise reduction space 1451 is formed between the noise reduction cover 144 and the upper end of the power cover 141. This noise reduction space 1451 can perform noise reduction functions, reducing the noise of the power assembly 14 and thus improving the user experience.

[0135] A filter element 146 is disposed on the upper end of the noise reduction cover 144. The filter element 146 can be connected to the upper end of the noise reduction cover 144 by means of, but not limited to, snap-fit ​​or plug-in connections. The filter element 146 performs a filtering function. A power drive unit 142 is disposed within the power chamber 1413 and is used to generate airflow from the filter element 146, the noise reduction cover 144, the air inlet 14111, and the air outlet 14121. Under the suction force of the power drive unit 142, as the airflow filtered by the dust cup assembly 16 is discharged from the bottom of the dust cup assembly 16 and enters the power assembly 14, the filter element 146 can further filter fine particles in the airflow. The airflow then flows along the noise reduction cover 144, the air inlet 14111, the power chamber 1413, and the air outlet 14121, thereby improving filtration efficiency. In addition, since the filter element 146 is located inside the noise reduction cover 144, the noise reduction cover 144 can block some fine dust and other particles from directly entering the power cover 141, thereby reducing the risk of damage to the power drive component 142 and thus improving the service life of the power drive component 142.

[0136] Therefore, through the combined action of the aforementioned power housing 141, power drive component 142, noise reduction housing 144, and filter component 146, not only is a noise reduction space 1451 formed between the noise reduction housing 144 and the upper part of the power housing 141, which can reduce the noise of the power component 14 and thus improve the user experience; but also, the filter component 146, located at the upper part of the noise reduction housing 144, can further filter fine particles in the airflow, thereby improving filtration efficiency; at the same time, the noise reduction housing 144 can prevent some fine dust from directly entering the power housing 141, which can reduce the risk of damage to the power drive component 142 and thus extend the service life of the power drive component 142.

[0137] In some embodiments, a noise-reducing connecting portion 1443 protrudes from the lower end of the noise-reducing cover 144. That is, the height of the noise-reducing connecting portion 1443 is higher than the height of the lower surface of the noise-reducing cover 144. The noise-reducing connecting portion 1443 is detachably or fixedly connected to the noise-reducing cover 144. The noise-reducing connecting portion 1443 is integrally formed into the noise-reducing cover 1444. The noise-reducing connecting portion 1443 serves a connecting function, communicating with the air inlet 14111, allowing airflow to move along the noise-reducing connecting portion 1443 to the air inlet 14111. When the noise-reducing connecting portion 1443 protrudes from the lower surface of the noise-reducing cover 144, it also provides some support, supporting at least a portion of the filter element 146, etc. When the filter element 146 is at least partially supported by the noise reduction connecting part 1443, since the height of the noise reduction connecting part 1443 is higher than the height of the lower surface of the noise reduction cover 144, an air intake space 1452 is formed between the filter element 146 and the lower surface of the noise reduction cover 144. This air intake space 1452 can increase the air intake volume, thereby reducing the risk of airflow blockage.

[0138] In some embodiments, along the direction from the upper end to the lower end of the noise-reducing cover 144, the cross-sectional area of ​​the lower end of the noise-reducing cover 144 gradually decreases in the direction perpendicular to the upper end to the lower end of the noise-reducing cover 144. The lower end of the noise-reducing cover 144 is inclined downwards in the direction from the upper end to the lower end of the noise-reducing cover 144. Because the noise-reducing space 1451 is formed between the lower end of the noise-reducing cover 144 and the upper end of the power cover 141, the cross-sectional area of ​​the noise-reducing space 1451 gradually increases in the direction perpendicular to the upper end to the lower end of the noise-reducing cover 144.

[0139] By gradually reducing the cross-sectional area of ​​the lower end of the noise reduction cover 144, not only can a noise reduction space 1451 be formed, but the noise of the power component 14 can also be reduced, thereby improving the user experience; it can also form an air intake space 1452, increasing airflow. In addition, by limiting the change in the cross-sectional area of ​​the lower end of the noise reduction cover 144, while simultaneously forming the aforementioned noise reduction space 1451 and air intake space 1452, the structure is more compact and occupies less space.

[0140] Please continue reading. Figures 29 to 31 In some embodiments, a support member 1441 is provided on the lower surface of the noise-reducing cover 144. The support member 1441 is detachably or fixedly connected to the bottom surface of the noise-reducing cover 144. The support member 1441 is integrally formed on the bottom surface of the noise-reducing cover 144. The support member 1441 has a supporting function and can be positioned at any position on the lower end of the noise-reducing cover 144, as long as it can support the filter element 146. By providing the aforementioned support member 1441 at the lower end of the noise-reducing cover 144, the stability of the filter element 146 can be improved. The number of support members 1441 can be, but is not limited to, one, two, or more than three. The shape of the support member 1441 can be, but is not limited to, straight, curved, or arc-shaped.

[0141] In some embodiments, at least two support members 1441 are radially disposed on the lower surface of the noise reduction cover 144. The number of support members 1441 may be, but is not limited to, two, three, or more than four. Adjacent support members 1441 are spaced apart. By limiting the radial arrangement of at least two support members 1441, the stability of the filter element 146 can be further improved. In addition, through the cooperation of the at least two support members 1441, the lower surface of the noise reduction cover 144, and the filter element 146, the air intake space 1452 can be divided into several different sub-air intake spaces 1452, thereby allowing airflow to enter the different sub-air intake spaces 1452.

[0142] When the above-mentioned at least two support members 1441 are arranged radially, the at least two support members 1441 are located at the outer periphery of the noise reduction connecting part 1443, and the support members 1441 are arranged radially.

[0143] In some embodiments, at least two support members 1441 are horizontally positioned at their upper ends, which ensures the balance of the filter element 146 at different positions and thus improves the stability of the filter element 146 installation. When the upper ends of different support members 1441 are horizontally positioned, the cross-sectional area of ​​the lower end of the noise reduction cover 144 gradually decreases along the direction perpendicular to the upper end of the noise reduction cover 144 to its lower end. As a result, the vertical distance between the support member 1441 and the lower end of the noise reduction cover 144 gradually increases from the outer periphery to the center of the noise reduction cover 144, thereby ensuring that the upper end of the support member 1441 is horizontally positioned.

[0144] Specifically, the upper end of the support member 1441 and the surface of the noise reduction connecting part 1443 are flush, which further ensures the balance of the filter member 146 at different positions.

[0145] In some embodiments, the support member 1441 includes at least one first sub-support member 14411 and at least one second sub-support member 14412. The number of first sub-support members 14411 may be, but is not limited to, one, two, or more than three. The number of second sub-support members 14412 may be, but is not limited to, one, two, or more than three. When there are multiple first sub-support members 14411 and multiple second sub-support members 14412, the first sub-support members 14411 and the second sub-support members 14412 are arranged at intervals; wherein, the multiple first sub-support members 14411 and the multiple second sub-support members 14412 are all radially arranged. For example, the first sub-support members 14411, the second sub-support members 14412, and the first sub-support members 14411 are arranged at intervals in sequence. Through the cooperation of at least one first sub-support member 14411 and at least one second sub-support member 14412, not only can the filter member 146 be supported, but different sub-intake spaces 1452 can also be formed, thereby increasing the air intake volume, etc.

[0146] Please continue reading. Figures 29 to 31 In some embodiments, a filter space 1442 is recessed in the upper part of the noise reduction cover 144. A filter support portion 1444 is provided around the lower periphery of the noise reduction cover 144. The filter support portion 1444 can support the bottom edge of the filter element 146. The filter element 146 is embedded in the filter space 1442, and the bottom edge of the filter element 146 is located at the filter support portion 1444. Through the cooperation of the filter space 1442 and the filter support portion 1444 on the noise reduction cover 144, the filter element 146 and the like can be supported.

[0147] The filter element 146 can be supported by at least one of the filter support 1444, the noise reduction connecting part 1443, and the support member 1441. The noise reduction cover 144 is provided with the filter support 1444, the noise reduction connecting part 1443, and the support member 1441, and all of the filter support 1444, the noise reduction connecting part 1443, and the support member 1441 serve to support the filter element 146.

[0148] In some embodiments, the filter element 146 is a sponge pad (not shown in the figure). The sponge pad can filter fine particles of dust, etc., is easy to replace, and is low in cost. The filter element 146 can also be other filter structures, which are not limited here.

[0149] In some embodiments, the power assembly 14 includes a safety valve (not shown in the figure). The safety valve is disposed on the noise reduction cover 144. The safety valve can be connected to the noise reduction cover 144 by means of, but not limited to, snap-fit, plug-in, or bolts. The safety valve can be disposed on the bottom surface of the noise reduction cover 144 or on a side of the noise reduction cover 144 opposite to the filter element 146. The safety valve is in an open-closed communication with the power chamber 1413. The safety valve has two states: open and closed. When the airflow in the dust cup assembly 16 and the power assembly 14 is normal, the safety valve is in the closed state. When the dust cup assembly 16 is full of dust, causing abnormal airflow, and the power assembly 14 is under negative pressure, the safety valve is in the open state, allowing airflow to enter the power chamber 1413, thereby dissipating heat from the power drive component 142 and reducing the risk of damage to the power drive component 142. The above-mentioned safety valve is a conventional component, and its operating principle will not be described in detail.

[0150] In some embodiments, a noise-reducing snap-fit ​​portion 1445 is provided at the top of the noise-reducing cover 144.
