Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaners, in particular to a handheld vacuum cleaner with a cleaning function. Background Art

[0002] In the field of handheld crevice cleaning equipment, traditional technologies generally have the defects of insufficient coordination between mechanical structure and function, which restricts cleaning efficiency and user experience. Existing steering mechanisms mostly rely on gear sets or friction plates to achieve angle fixation. The adjustment process requires two-handed operation and there is a problem of locking force attenuation, which leads to frequent resetting when working at high altitude or in narrow spaces, and limited operational fluency. Cleaning mechanisms often use a rigid bracket and a fixed-pitch bristle design, which is difficult to adapt to gaps with gradual width or asymmetric cross-sections such as door and window slides. The uneven distribution of bristle pressure can easily cause cleaning blind spots or surface damage. Existing elastic compensation solutions also fail to achieve a dynamic balance between deformation and cleaning force.

[0003] In addition, liquid supply control is mostly achieved through solenoid valves or manual knobs. The response delay of the former can easily cause waste of liquid in shallow gaps, while the latter relies on manual prediction and cannot adapt to complex working conditions. The existing sensor feedback scheme is difficult to put into practical use due to the complexity of the system. In addition, there is a problem of timing disconnection in the step-by-step operation mode of wet cleaning and dry vacuuming. Liquid residue causes secondary pollution, and the asynchrony between the vacuum port and the movement trajectory of the cleaning brush causes dust to escape. The existing synchronization scheme still cannot effectively capture dust due to the misalignment of the negative pressure peak and the dirt stripping moment. The essence of the above problems lies in the fact that the existing technology lacks a closed-loop coordination mechanism for multiple physical quantities such as mechanical deformation, liquid flow, and vacuum negative pressure. The independent operation of each subsystem leads to low energy efficiency. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please see attached Figure 1 -Attached Figure 8 An embodiment of the present invention provides a handheld vacuum cleaner with a cleaning function, including a handle member 1, a storage chamber 2 is provided on one side of an outer wall of the handle member 1, liquid is stored in the storage chamber 2, one end of an extension rod 3 is fixedly connected to one side of the outer wall of the handle member 1, the other end of the extension rod 3 is fixedly connected to a steering mechanism, a cleaning mechanism is fixedly connected to one side of the outer wall of the steering mechanism, the cleaning mechanism extends into the gap for cleaning, an adjusting component is also installed inside the cleaning mechanism, which self-adjusts the liquid flow, a hose 4 is connected to one side of the outer wall of the storage chamber 2, one end of the hose 4 is connected to the adjusting component, and a dust collection mechanism is installed on one side of the outer wall of the extension rod 3.

[0021] The steering mechanism includes a fixed shaft 5, one end of the fixed shaft 5 is fixedly connected to the extension rod 3, the other end of the fixed shaft 5 is rotatably connected to a bow plate 6, one side of the inner wall of the bow plate 6 is fixedly connected to a ratchet 7, one end of an auxiliary push rod 8 is fixedly connected to one side of the outer wall of the fixed shaft 5, the other end of the auxiliary push rod 8 is fixedly connected to one end of a short shaft 9, the other end of the short shaft 9 is rotatably connected to a pawl 10, one end of a torsion spring 11 is fixedly connected to one side of the outer wall of the auxiliary push rod 8, and the other end of the torsion spring 11 is fixedly connected to the pawl 10.

[0022] Specifically, the steering mechanism realizes the one-way locking function through the meshing of the ratchet 7 and the pawl 10. When the user presses the auxiliary push rod 8, the short shaft 9 drives the pawl 10 to disengage from the ratchet 7, and the arch plate 6 can rotate freely; after the pressure is released, the torsion spring 11 drives the pawl 10 to reset and re-engage the ratchet 7 tooth groove to fix the cleaning mechanism angle, allowing the user to adjust the cleaning head angle with one hand to adapt to the cleaning of gaps at different heights. The ratchet structure provides stable locking to avoid angle deviation during cleaning. The one-way locking mechanism does not require continuous force, reducing the burden on the hands during long-term operation.

[0023] The cleaning mechanism includes a cleaning plate 12, which is fixedly connected to one side of the outer wall of the arch plate 6. Slideways 13 are provided on both sides of the inner wall of the cleaning plate 12. A telescopic plate 14 is slidably connected inside the slideway 13. Telescopic rods 15 are fixedly connected to both ends of the inner wall of the cleaning plate 12. The output ends of the two telescopic rods 15 are respectively fixedly connected to the corresponding telescopic plates 14. A cleaning brush 16 is installed on one side of the outer wall of the telescopic plate 14.

[0024] Specifically, when the cleaning plate 12 is placed in the window gap, the outer walls on both sides of the window iron slide rail squeeze the telescopic plate 14. When the telescopic plate 14 partially contracts, the side section of the cleaning brush 16 is consistent with the side section of the iron slide rail. The telescopic rod 15 pushes the telescopic plate 14 to extend and retract laterally along the slide 13, driving the cleaning brush 16 to fit the wall of the gap. The cleaning brush 16 is made of flexible material to achieve two-way cleaning.

[0025] The adjustment component includes an extension plate 17, which is fixedly connected to one side of the outer wall of the cleaning plate 12, one end of the hose 4 is connected to the extension plate 17, one side of the inner wall of the extension plate 17 is fixedly connected to a uniformly distributed partition plate 18, one side of the outer wall of the partition plate 18 is provided with holes, one end of a spring 19 is fixedly connected to one side of the inner wall of the extension plate 17, the other end of the spring 19 is fixedly connected to a water guide column 20, a liquid outlet 21 is provided at the bottom of the extension plate 17, the liquid outlet 21 is connected to the cleaning plate 12, one end of a long rod 22 is fixedly connected to the inside of the telescopic plate 14, and the other end of the long rod 22 passes through the liquid outlet 21.

[0026] The water guide column 20 is trapezoidal in shape. One end of a telescopic column 28 is fixedly connected to one side of the outer wall of the water guide column 20 , and the other end of the telescopic column 28 is connected to the inner wall of the extension plate 17 .

[0027] One end of the long rod 22 is fixedly connected to a cross bar 26, and the cross bar 26 is retractable.

[0028] Specifically, when the telescopic plate 14 contacts the iron slide rail and contracts, it drives the long rod 22 to move toward the extension plate 17, pushing the water guide column 20 to compress the spring 19, so that a gap is formed between the trapezoidal slope of the water guide column 20 and the partition plate 18, and the liquid flows out from the liquid outlet 21 through the hole, and the flow rate is proportional to the telescopic distance, that is, the deeper the inside of the iron slide rail to be cleaned, the greater the contraction distance of the telescopic plate 14, and the greater the distance the long rod 22 is driven to move upward. At this time, the larger the gap formed between the trapezoidal slope of the water guide column 20 and the partition plate 18, the water flow rate increases accordingly, thereby meeting the targeted cleaning of iron slide rails of different depths.

[0029] The dust suction mechanism includes a dust suction port 23, one side of the outer wall of the dust suction port 23 is connected to one end of a curved pipe 24, and the other end of the curved pipe 24 is fixedly connected to the bottom of the telescopic plate 14; Specifically, the dust suction port 23 is connected to the bottom of the telescopic plate 14 through the curved pipe 24. When the cleaning brush 16 raises dust, the negative pressure airflow immediately sucks the dirt into the dust collection bin inside the extension rod 3, realizing the simultaneous operation of "wet cleaning + dry dust suction" and extracting the cleaned liquid during the cleaning of the iron slide rail.

[0030] A water pump 25 is fixedly connected to one side of the outer wall of the storage chamber 2, the input end of the water pump 25 is connected to the storage chamber 2, and the output end of the water pump 25 is connected to the hose 4; The outer walls of the extension rod 3 and the arched plate 6 are both provided with fixed arc plates 27 , and the hose 4 is fixed to the outer walls of the extension rod 3 and the arched plate 6 through the fixed arc plates 27 .

[0031] Specifically, the water pump 25 adopts a micro brushless motor, and the output pressure (0.2-0.5MPa) is controlled by a PID algorithm. The hose 4 is embedded with an anti-wrinkle spiral steel wire, and the snap-on design of the fixed arc plate 27 is used to ensure stable flow when bent at any angle.

[0032] Working principle: The vacuum cleaner realizes intelligent gap cleaning through the coordinated action of the steering mechanism, the cleaning mechanism and the adjustment component. In the steering mechanism, the auxiliary push rod 8 can drive the short shaft 9 to retract, and the short shaft 9 drives the pawl 10 to disengage the ratchet 7, so that the arch plate 6 can rotate freely to adjust the cleaning angle; after releasing the pressure, the torsion spring 11 drives the pawl 10 to reset and engage with the tooth groove of the ratchet 7, locking the cleaning mechanism angle to ensure the stability of one-hand operation. When the cleaning mechanism goes deep into the gap, the telescopic plate 14 is squeezed and contracted by the gap wall, driving the telescopic rod 15 to push the flexible cleaning brush 16 to fit the gap wall, and remove stains through two-way friction. In the adjustment component, the contraction linkage long rod 22 of the telescopic plate 14 pushes the water guide column 20 to compress the spring 19, so that a gap is formed between the trapezoidal water guide column 20 and the partition plate 18, and the liquid flows out quantitatively from the liquid outlet 21 through the hole, and the flow rate is adaptively adjusted with the telescopic distance to meet the cleaning needs of gaps of different depths. The synchronously operated dust suction mechanism is connected to the dust suction port 23 at the bottom of the telescopic plate 14 through the curved pipe 24. When the cleaning brush 16 raises dust, the negative pressure airflow immediately sucks the dirt and residual liquid into the dust collection bin, realizing the three-dimensional operation of "wet cleaning and softening + dry dust collection and recovery". The water pump 25 dynamically adjusts the output pressure through the PID algorithm, and cooperates with the hose 4 with an embedded anti-wrinkle spiral steel wire and the snap-on fixing design of the fixed arc plate 27 to ensure stable liquid delivery. The overall structure adopts a low center of gravity design with a handle integrated storage cavity 2, combined with an ergonomic rubber-coated handle, which significantly reduces operating fatigue and is suitable for efficient cleaning of scenes such as door and window slides and furniture gaps.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
