[0028] This application relates to a multifunctional vacuum cleaner device, such as Figure 1-5As shown, the multi-functional vacuum cleaner 100 includes a movable cleaning base 1, a push rod 2 rotatably hinged to the cleaning base 1, and a portable vacuum module 3 detachably mounted on the push rod 2. The cleaning base 1 has a nozzle 11 facing the ground at its bottom. The push rod 2 pushes the cleaning base 1 back and forth on the ground for cleaning. The portable vacuum module 3 extends in a longitudinal direction and includes a dust cup 31 and a suction motor 32. When the portable vacuum module 3 is mounted on the push rod 2, the dust cup 31 is in fluid communication with the nozzle 11. Through the suction action of the suction motor 32, the nozzle 11 draws dust from the ground into the dust cup 31 as the cleaning base 1 moves along the ground. When the portable vacuum module 3 is detached from the push rod 2, it can be used as an independent component, allowing the user to hold the portable vacuum module 3 and clean different surfaces. The multi-functional vacuum cleaner 100 achieves dual functionality through the detachable connection between the portable vacuum module 3 and the push rod 2, reducing equipment purchase costs and storage space.

[0029] The push rod 2 is provided with an upper fixed seat 4 and a lower support seat 5 that are opposite each other. The upper fixed seat 4 is configured to slide on the push rod 2 between a first position and a second position, and the lower support seat 5 is fixedly installed on the push rod 2.

[0030] Continue to refer to Figure 2 When the upper fixed seat 4 is in the first position, the distance D1 between the upper fixed seat 4 and the lower support seat 5 in the vertical direction is adapted to the longitudinal height H of the portable vacuum module 3. The portable vacuum module 3 can be held between the upper fixed seat 4 and the lower support seat 5, thereby fixing it on the push rod 2 and forming an integral device with the cleaning base 1. This integral device cleans the ground by moving the cleaning base 1 back and forth.

[0031] Continue to refer to Figure 3 and Figure 4 When the upper fixed base 4 is in the second position, the vertical distance D2 between the upper fixed base 4 and the lower support base 5 is greater than the longitudinal height H of the portable vacuum module 3. At this point, the distance between the upper fixed base 4 and the lower support base 5 provides ample space for the portable vacuum module 3, allowing it to be quickly removed from between them. This facilitates operation, minimizes damage to components, shortens operation time, and improves cleaning efficiency. After the portable vacuum module 3 is removed from between the upper fixed base 4 and the lower support base 5, the user can hold the portable vacuum module 3 for independent cleaning operations, offering high flexibility.

[0032] The portable vacuum module 3 includes a first end 301 and a second end 302 that are spaced apart from each other in the longitudinal direction, with the first end 301 located below the second end 302.

[0033] like Figure 4-7As shown, a suction port 33 fluidly communicates with the dust cup 31 at the first end 301, and an opening 51 communicating with the suction nozzle 11 is provided at the lower support 5. When the portable vacuuming module 3 is held between the upper fixed base 4 and the lower support 5, the suction port 33 and the opening 51 are fluidly connected. The suction nozzle 11, the opening 51, the suction port 33, the dust cup 31, and the suction motor 32 are fluidly connected in sequence to form a suction channel. The suction motor 32 applies negative pressure at the suction nozzle 11, causing dust on the ground to be sucked from the suction nozzle 11 into the suction channel, thus cleaning the ground. During the cleaning operation, the sucked-in dust is collected and temporarily stored in the dust cup 31.

[0034] A protrusion 34 is provided at the first end 301, and the suction port 33 is located at the protrusion 34. When the portable vacuum module 3 is held between the upper fixed seat 4 and the lower support seat 5, the protrusion 34 is inserted into the opening 51, which improves the accuracy of the docking between the suction port 33 and the opening 51 and reduces the difficulty of docking between the two.

[0035] The upper fixing seat 4 has a recess 41 on its inner side, and the shape of the recess 41 is adapted to the second end 302; when the portable vacuuming module 3 is held between the upper fixing seat 4 and the lower support seat 5, the second end 302 is located at the recess 41.

[0036] The upper fixing seat 4 has a cap-shaped structure. When the portable vacuum module 3 is held on the push rod 2, the upper fixing seat 4, which is cap-shaped, cooperates with the second end 302 and the protrusion 34 cooperates with the opening 51 to ensure the stability of the portable vacuum module 3 held between the upper fixing seat 4 and the lower support seat 5. This effectively prevents the portable vacuum module 3 from falling off the push rod 2 due to loose fit, and improves the stability of the equipment operation.

[0037] like Figure 6-11 As shown, the second end 302 is provided with an exhaust port 303, which is fluidly connected to the outside and the suction motor 32, for the suction motor 32 to exhaust air outward. The upper fixed base 4 has multiple openings 42 that pass through the recess 41 and the outside. When the portable vacuum module 3 is held between the upper fixed base 4 and the lower support base 5, the exhaust port 303 is fluidly connected to the multiple openings 42. The multiple openings 42 are spaced circumferentially. On the one hand, the multiple openings 42 allow for normal ventilation when the portable vacuum module 3 is installed on the push rod 2; on the other hand, they change the direction of the air exhausted by the suction motor 32, preventing the exhaust gas from directly hitting the user holding the push rod 2 and affecting the user's experience.

[0038] like Figure 10 , 11As shown, a locking mechanism 6 is provided between the push rod 2 and the upper fixed seat 4. The locking mechanism 6 includes a locking pin 61 located on the push rod 2, a first locking groove 62 and a second locking groove 63 located on the upper fixed seat 4 and distributed in the vertical direction. The first locking groove 62 is located on the upper side of the second locking groove 63.

[0039] like Figure 5-6 As shown, when the upper fixed seat 4 is in the first position, the locking pin 61 engages with the first locking groove 62; as Figure 9-10 As shown, when the upper fixed seat 4 is in the second position, the locking pin 61 engages with the second locking groove 63.

[0040] Continue to refer to Figure 5 , Figure 6 , Figure 9 , Figure 10 and Figure 11 The locking mechanism 6 can lock the upper fixed seat 4 in either the first or second position, preventing the unlocked upper fixed seat 4 from affecting the installation and removal of the portable vacuum module 3. The locking mechanism 6 effectively improves the stability of the multi-functional vacuum cleaner 100 when the portable vacuum module 3 is installed on the push rod 2. The locking pin 61 is supported on the push rod 2 by a spring 64 that can elastically deform in the lateral direction. During the switching between the first and second positions of the upper fixed seat 4, the locking pin 61 is pushed laterally into the push rod 2 by the inner wall surface of the upper fixed seat 4. The spring 64 is compressed under the pushing action. When the locking pin 61 moves to the first locking groove 62 or the second locking groove 63, the spring 64 releases its elastic force to push the locking pin 61 into the corresponding locking groove, thereby locking the position of the upper fixed seat 4. The locking mechanism 6 facilitates flexible adjustment of the upper fixed seat 4 between the first and second positions, has a simple structure, and is not easily damaged.

[0041] like Figure 2 , 5 As shown, the cleaning base 1 is configured to attach a cleaning pad 7, with the attachment area of ​​the cleaning pad 7 avoiding the nozzle 11 to prevent affecting the suction force at the nozzle 11. The cleaning pad 7 is used to wipe the ground where the nozzle 11 passes during the movement of the cleaning base 1, thereby improving the cleaning effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
