Description

Technical Field

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

[0002] Current handheld vacuum cleaners typically use a linkage to connect the main unit to components such as the ground brush. To accommodate different user postures, some linkage structures are telescopic. During length adjustment and use, the internal wiring for powering the ground brush and transmitting control commands automatically folds or extends. However, bent or clumped wiring can lead to unstable power supply, causing the telescopic linkage to jam and become immobile. Furthermore, using the vacuum cleaner before the telescopic linkage is fully formed or the internal flow channels are stably connected can result in erroneous operation, leading to dust-laden airflow leakage, structural wobbling, and other inconveniences. Therefore, it is evident that current vacuum cleaners have certain shortcomings in terms of intelligent, convenient, and user-friendly design. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing handheld vacuum cleaners, such as the instability of power supply caused by the bending and local accumulation of internal wiring in the telescopic linkage, the jamming of the telescopic linkage structure, the possibility of erroneous operation when the telescopic linkage is not fully formed, and the lack of foolproof design, which result in insufficient intelligence and ease of use of the vacuum cleaner. Therefore, this invention provides a handheld intelligent vacuum cleaner.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a handheld intelligent vacuum cleaner, comprising:

[0005] Floor brush;

[0006] Vacuum cleaner main unit;

[0007] The telescopic linkage includes a lower linkage and an upper linkage that slide and engage with each other. One end of the lower linkage engages with the floor brush. A button seat is provided at the other end of the lower linkage near the upper linkage. A button assembly is provided on the button seat. The button assembly includes a button body hinged to a hinge seat on the button seat. An elastic element is provided between one end of the button body and the hinge seat. A locking block at the other end passes through a through hole in the button seat. A first electrical contact is provided at the inner end of the locking block. The first electrical contact is electrically connected to an electrical device on the floor brush. The upper end of the upper linkage engages with the air intake structure of the vacuum cleaner main unit through a connecting seat.

[0008] A snap-fit ​​plate is embedded in the groove of the upper connecting rod, and a number of snap-fit ​​slots corresponding to the snap-fit ​​block are provided through and spaced apart on it;

[0009] A power connector is disposed in the groove, and a plurality of second power contacts corresponding to the first power contacts are arranged on it at intervals. The second power contacts are electrically connected to the power supply control module of the vacuum cleaner host.

[0010] As a further description of the above technical solution:

[0011] The lower connecting rod includes an inner flow tube and an outer tube, and a receiving cavity is formed between the inner flow tube and the outer tube. The lower end of the tubular upper connecting rod is slidably inserted into the receiving cavity at the other end of the lower connecting rod and closely fits the surfaces of the inner flow tube and the outer tube. The button seat is disposed on the outer tube.

[0012] As a further description of the above technical solution:

[0013] The inner flow tube is equipped with a sealing sleeve, and the sealing sleeve is airtightly fitted to the inner wall of the upper connecting rod.

[0014] As a further description of the above technical solution:

[0015] The upper end of the snap-fit ​​plate is fitted onto the surface of the connector, and fasteners are assembled into the mounting holes of the connector and the snap-fit ​​plate.

[0016] As a further description of the above technical solution:

[0017] The inner end face of the snap-fit ​​plate is provided with a sealing film, and the sealing film is provided with a number of slits that correspond to the snap-fit ​​opening and can be elastically expanded and deformed.

[0018] As a further description of the above technical solution:

[0019] The surfaces of the first and second electrical contacts are provided with a conductive protective layer.

[0020] As a further description of the above technical solution:

[0021] The snap-fit ​​plate is an elastic structure and is movably disposed within the groove.

[0022] As a further description of the above technical solution:

[0023] The side of the groove extends into a limiting groove, the snap-fit ​​plate passes through the limiting groove, and the elastic piece at the notch on its side elastically abuts against the inner wall of the limiting groove.

[0024] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0025] 1. The vacuum cleaner of this invention uses a telescopic connecting rod to connect the floor brush and the main unit. The telescopic rod's adjustable length allows for adjustment of the height of the main unit, facilitating easy handheld gripping and use. This adapts to users of different heights, providing a comfortable operating posture and enhancing user experience and comfort. The power supply line between the floor brush and the main unit, passing through the telescopic connecting rod, employs a two-section design: one section connects to the electrical device and button body of the floor brush, while the other section connects to the main unit and the power socket. When the telescopic connecting rod is at different lengths, the locking block engages with the locking plate, achieving overall stability of the telescopic connecting rod. In this design, the first electrical contact aligns with the corresponding second electrical contact, establishing a power supply connection. Compared to conventional telescopic linkages, the integrated internal power supply system's adaptive folding and extension avoids issues like power instability caused by bent or clumped wires, and structural jamming of the telescopic linkage. Furthermore, electrical connection between the button body and the locking plate is only achieved when they are engaged, allowing the floor brush to be powered and activated. This design prevents accidental operation when the telescopic linkage is not fully fixed or the internal flow channels are not stably aligned during installation and adjustment, improving ease of use. This design achieves intelligent, convenient, and user-friendly operation of the handheld vacuum cleaner.

[0026] 2. The upper end of the snap-fit ​​plate is positioned on the connecting seat. Its lower end can deform when the button body is snapped into the snap-fit ​​plate to buffer impact forces, preventing direct impact on the upper connecting rod and thus avoiding damage. This improves the service life of the telescopic connecting rod and reduces damage during use. The elastic sheet and the limiting groove elastically abut against each other, providing secondary buffering against impact forces and further improving the structure's impact resistance. Furthermore, based on the above structural design, when the telescopic connecting rod is in a long-duration state, the elastic structure will adaptively deform under the elastic compression of the button body connected to the elastic element. This compensates for the positional misalignment between the button body and the contact seat caused by the deformation of the telescopic connecting rod, ensuring stable connection of the electrical contacts.

[0027] 3. The sealing membrane isolates the electrical base from the external environment, preventing oxidation and contamination of the second electrical contact point, which could affect its conductivity. During use, the locking block is pressed against the corresponding slit, causing it to open gradually. Under the elastic force of the elastic element, the button body pushes the locking block inward, allowing it to pass through the opened slit and connect the electrical contacts. This fulfills the functions of the electrical base's built-in isolation and convenient button engagement for easy power connection. Furthermore, after the locking block engages, the frictional resistance between the slit and the locking block prevents relative movement and loosening, further improving the engagement strength and the stability of the telescopic linkage.

[0042] Example 1:

[0043] Please see Figure 1-6 The present invention provides a technical solution: a handheld intelligent vacuum cleaner, comprising:

[0044] Floor brush 1;

[0045] Vacuum cleaner main unit 2;

[0046] The telescopic linkage includes a lower linkage 3 and an upper linkage 4 that slide and connect with each other. One end of the lower linkage 3 is connected to the floor brush 1. A button seat 8 is provided at the other end of the lower linkage 3 near the upper linkage 4. A button assembly 9 is provided on the button seat 8. The button assembly 9 includes a button body 11 that is hinged to a hinge seat 10 on the button seat 8. An elastic element 12 is provided between one end of the button body 11 and the hinge seat 10. A locking block 13 at the other end passes through a through hole 14 in the button seat 8. A first electrical contact 15 is provided at the inner end of the locking block 13. The first electrical contact 15 is electrically connected to the electrical device on the floor brush 1. The upper end of the upper linkage 4 is connected to the air intake structure of the vacuum cleaner main unit 2 through a connecting seat 16.

[0047] The snap-fit ​​plate 18 is embedded in the groove 17 of the upper connecting rod 4, and has several snap-fit ​​openings 19 that are spaced apart and correspond to the snap-fit ​​block 13.

[0048] A power connector 20 is disposed in the groove 17, and a plurality of second power contacts 21 corresponding to the first power contact 15 are arranged on it at intervals. The second power contacts 21 are electrically connected to the power supply control module of the vacuum cleaner main unit 2.

[0049] The working principle of a handheld smart vacuum cleaner in this embodiment includes: the vacuum cleaner of the present invention connects the floor brush 1 and the vacuum cleaner main unit 2 through a telescopic connecting rod. The telescopic rod's length is adjustable to adjust the height of the vacuum cleaner main unit 2, making it convenient for users to hold and use the vacuum cleaner. This adapts to the needs of users of different heights to operate the vacuum cleaner in a suitable body posture, improving user experience and comfort. The power supply line between the floor brush 1 and the vacuum cleaner main unit 2, passing through the telescopic connecting rod, adopts a two-section design: one section connects to the electrical device and button body 11 of the floor brush 1 via a locking block 13, and the other section connects to the vacuum cleaner main unit 2 and the power socket 20. When the telescopic connecting rod is at different lengths, the locking block 13 engages with the locking plate 1. The latch 19 at position 8 achieves overall shaping of the telescopic linkage. At this point, the first electrical contact 15 connects with the corresponding second electrical contact 21, connecting the power supply line. Compared to the conventional telescopic linkage's telescopic movement, the internal integrated power supply line's adaptive folding or extension avoids problems such as unstable power supply caused by wire bending or local accumulation, and the telescopic linkage structure becoming stuck and unable to move. Furthermore, the electrical connection between the electrical contacts on the button body 11 and the latch plate 18 is only achieved when they are latched together, allowing the floor brush to be powered and used. This design prevents accidental operation when the telescopic linkage is not fully shaped or the internal flow channel is not stably connected during installation and adjustment, improving ease of use. Through the above design, the handheld vacuum cleaner achieves intelligent, convenient, and user-friendly operation.

[0050] Example 2:

[0051] Please see Figure 3 , 4 The figure shows a handheld intelligent vacuum cleaner according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: The lower connecting rod 3 includes an inner flow tube 5 and an outer sleeve 6, forming a receiving cavity 7 between the inner flow tube 5 and the outer sleeve 6. The lower end of the tubular upper connecting rod 4 is slidably inserted into the receiving cavity 7 at the other end of the lower connecting rod 3 and tightly adheres to the surfaces of the inner flow tube 5 and the outer sleeve 6. The button seat 8 is disposed on the outer sleeve 6. The inner flow tube 5 is provided with a sealing sleeve 22, which airtightly adheres to the inner wall of the upper connecting rod 4. The inner flow tube 5, the outer sleeve 6, and the tubular upper connecting rod 4 form a multi-layered insertion structure, improving the structural strength of the telescopic connecting rod and preventing excessive deformation that could affect user operation when used at its maximum length. Furthermore, the sealing sleeve 22 ensures a more thorough sealing of the internal flow channels, preventing air leakage and the ingestion of dust and hair from the vacuum cleaner into the receiving cavity 7, thus avoiding internal structural contamination.

[0052] Example 3:

[0053] Please see Figure 3-6 The figure shows a handheld intelligent vacuum cleaner according to Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: the upper end of the snap-fit ​​plate 18 is fitted onto the surface of the connecting seat 16, and fasteners are assembled on the mounting holes 23 of the connecting seat 16 and the snap-fit ​​plate 18. This facilitates the disassembly, assembly, and replacement of the snap-fit ​​plate 18, ensuring its full engagement with the button and stable use of the telescopic linkage.

[0054] The snap-fit ​​plate 18 is an elastic structure that is movably disposed within the groove 17. A limiting groove 26 extends from the side of the groove 17, and the snap-fit ​​plate 18 passes through the limiting groove 26. An elastic piece 27 at the notch on its side elastically abuts against the inner wall of the limiting groove 26. The upper end of the snap-fit ​​plate 18 is positioned on the connecting seat 16, and its lower end can deform when the button body 11 is snapped into place with the snap-fit ​​plate 18 to buffer the impact force, preventing the impact force from directly acting on the upper connecting rod 4 and causing damage to its mass. This improves the service life of the telescopic connecting rod and reduces damage during use. The elastic piece 27 elastically abuts against the limiting groove 26, providing secondary buffering against the impact force and further improving the structure's impact resistance. Furthermore, based on the above structural design, when the telescopic connecting rod is in a long-duration usage state, the elastic structure will adaptively deform under the elastic compression of the button body 11 connected to the elastic element 12 to compensate for the positional offset between the button body 11 and the contact seat 20 caused by the deformation of the telescopic connecting rod, ensuring stable connection of the contact points.

[0055] Example 4:

[0056] Please see Figure 3-5 The figure shows a handheld intelligent vacuum cleaner provided in Embodiment 4 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: a sealing film 24 is provided on the inner end face of the snap-fit ​​plate 18. The sealing film 24 has several slits 25 at intervals corresponding to the snap-fit ​​opening 19 and capable of elastic expansion and deformation. The sealing film 24 isolates the power base 20 from the external environment, preventing oxidation and contamination of the second power contact 21, which would affect its conductivity. In use, the snap-fit ​​block 13 presses against the corresponding slit 25, causing it to open gradually. Under the elastic force of the elastic element 12, the button body 11 pushes the snap-fit ​​block 13 inward, allowing it to pass through the opened slit 25 and connect the power contacts. This satisfies the functions of the built-in isolation of the power base 20, facilitating button snap-fit ​​and convenient power connection. Furthermore, after the snap-fit ​​block 13 is engaged, the frictional resistance between it and the slit 25 prevents relative movement and loosening, further improving the snap-fit ​​strength and the stability of the telescopic linkage.

[0057] The surfaces of the first electrical contact 15 and the second electrical contact 21 are provided with a conductive protective layer to protect the electrical contacts, improve their stability of physical and chemical properties such as oxidation resistance, and ensure stable conductivity. In addition, components that do not require conductivity, such as the snap-fit ​​plate 18, the button body 11, and the telescopic linkage main structure, must be made of insulating materials to avoid potential hazards such as leakage and electric shock to users.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
