Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a handheld vacuum cleaner with an independent and detachable HEPA module. Background Technology

[0002] In existing filtration devices, HEPA (High-Efficiency Particulate Air) filters are typically integrated into the fixed structure of the device, tightly bound to other filtration stages (such as a metal mesh pre-filter). For example, utility model patent CN 203861142 U discloses a vacuum cleaner equipped with a HEPA filtration system. While this design enables multi-stage filtration, it also introduces the following problems:

[0003] Inconvenient maintenance: Because the HEPA filter is fixedly connected to other filtration stages, users need to disassemble the entire filtration system when cleaning or replacing it, which is cumbersome and can easily affect other components.

[0004] Low cleaning efficiency: Dust and debris may accumulate in the gaps of the HEPA filter or other filter layers, making it difficult to clean thoroughly. Long-term accumulation will reduce filtration efficiency.

[0005] Limited lifespan: The fixed design means that HEPA filters cannot be maintained or replaced individually, and may fail prematurely due to localized contamination, increasing operating costs.

[0006] In addition, while existing metal mesh filter layers (such as the single-cone Circle design) can intercept larger particles, their integration with HEPA filters often lacks flexibility and cannot achieve modular, independent functionality. Utility Model Content

[0007] To address the aforementioned technical issues, this invention provides a handheld vacuum cleaner with an independent, detachable HEPA module. By treating the HEPA layer as an independent module, it enables convenient removal, separate cleaning, and maintenance, thereby improving filtration efficiency, extending service life, and reducing the difficulty of operation for users.

[0008] Specifically, this utility model discloses a handheld vacuum cleaner with an independently detachable HEPA module, comprising:

[0009] Vacuum cleaner body;

[0010] The HEPA module is detachably installed inside the vacuum cleaner body and includes: a module housing, a HEPA filter layer, and a top cover. The HEPA filter layer is disposed inside the module housing, and the top cover is connected to the module housing.

[0011] The dust cup filter module is detachably installed inside the vacuum cleaner body and includes a dust cup body, a filter screen, and a side cover. The filter screen is installed inside the dust cup body, and the side cover is connected to the dust cup body and can be opened and closed.

[0012] The advantage of adopting the above technical solution is that, by setting up an independent and detachable HEPA module, users can easily clean or replace the HEPA filter layer without disassembling the entire filtration system, greatly reducing the difficulty of maintenance. Furthermore, both the HEPA module and the dust cup filter module are detachable, working independently yet collaboratively to effectively filter dust and impurities of different particle sizes.

[0013] Furthermore, the bottom of the module housing is provided with multiple air inlets, and the bottom of the module housing is provided with a bottom cover, with ventilation cavities left between the bottom cover and the module housing.

[0014] The advantages of adopting the above technical solution are that the placement of air inlet one allows air to enter the HEPA module more smoothly. Multiple air inlets increase the air intake area and improve air intake efficiency, allowing more air to quickly enter the module housing and be filtered by the HEPA filter layer. Simultaneously, the ventilation chambers between the bottom cover and the module housing act as buffers and diverts airflow. When air enters through air inlet one, it undergoes some diffusion and buffering within the ventilation chambers, preventing direct impact on the HEPA filter layer, reducing damage, and extending its lifespan. Furthermore, the ventilation chambers allow for more even air distribution within the module housing, ensuring that all parts of the HEPA filter layer can fully perform their filtering function, improving the overall filtration effect. In addition, this air intake design also helps reduce wind noise, making the vacuum cleaner quieter during operation and enhancing the user experience.

[0015] Furthermore, the module housing is provided with a snap-fit ​​part, and the vacuum cleaner body has an outer shell, which is provided with a mating groove that cooperates with the snap-fit ​​part.

[0016] The advantage of adopting the above technical solution is that the engagement of the snap-fit ​​part and the mating groove achieves a stable connection between the HEPA module and the vacuum cleaner body. When the HEPA module is installed into the vacuum cleaner body, the snap-fit ​​part can accurately engage with the mating groove, ensuring that the HEPA module is fixed in position within the vacuum cleaner body and will not shake or shift during use, thus ensuring the normal operation of the entire vacuum cleaner. At the same time, this snap-fit ​​method also facilitates the disassembly and installation of the HEPA module. When cleaning or replacing the HEPA filter layer, users only need to apply slight force to detach the snap-fit ​​part from the mating groove, easily removing the HEPA module from the vacuum cleaner body; and during installation, the HEPA module can be quickly and accurately installed into place using the engagement of the snap-fit ​​part and the mating groove, making the operation simple and convenient.

[0017] Furthermore, the vacuum cleaner body has a suction pipe, a fan, and a handheld part. The fan is located on one side of the HEPA module, and the HEPA module has an outlet that communicates with the fan. The dust cup filter module is located between the HEPA module and the suction pipe and communicates with both the HEPA module and the suction pipe.

[0018] The advantage of adopting the above technical solution is that, during use, dust and impurities enter the dust cup filter module through the suction pipe for initial filtration, and then enter the HEPA module for secondary filtration. The fan provides suction, allowing air to flow smoothly between the modules, completing the efficient filtration process. This reasonable layout design ensures a tight and smooth connection between the modules, guaranteeing the high efficiency of the entire suction and filtration process.

[0019] Furthermore, the upper cover is provided with an air outlet, and a protruding ring is provided along the outer edge of the air outlet. The protruding ring is connected to the fan and is equipped with a sealing ring.

[0020] The advantages of adopting the above technical solution are that the protruding ring facilitates the connection between the HEPA module and the fan, while the sealing ring ensures the sealing of the connection, so that the suction force generated by the fan does not leak, ensuring the efficient operation of the vacuum cleaner.

[0021] Furthermore, one end of the side cover is hinged to the dust cup body, the side cover is provided with a sliding groove, a sliding block is provided in the sliding groove, the sliding block is provided with a protruding head, and the dust cup body is provided with a groove that cooperates with the protruding head.

[0022] The advantages of adopting the above technical solution are that the hinged side cover can be opened from the side to pour out the internal dust. It is opened by moving the sliding block, which is simple to operate and does not require disassembling screws. In addition, during use, the protruding head is always in the groove without being touched, which prevents the side cover from opening during use and facilitates cleaning of the inside of the dust cup body.

[0023] Furthermore, a protruding block is provided at the bottom of the dust cup body, and a rotating block is installed on the vacuum cleaner body. The rotating block is rotatably installed and has an inner concave surface that cooperates with the protruding block. By pressing the rotating block to make it rotate, the protruding block disengages from the inner concave surface, and the dust cup body can be completely disassembled.

[0024] The advantage of adopting the above technical solution is that it allows for the complete disassembly of the dust cup body, facilitating a more comprehensive and thorough cleaning of the interior. When a large amount of dust and debris that is difficult to empty through the side cover accumulates inside the dust cup body, pressing the rotating block separates the dust cup body from the vacuum cleaner body, allowing for deep cleaning of every corner of the dust cup body. This ensures the cleaning effect of the dust cup body, thereby guaranteeing the filtration performance of the dust cup filter module, making cleaning convenient and quick.

[0025] Furthermore, the dust cup body is equipped with a dust cup cover, and an air outlet is provided in the middle of the dust cup cover. The dust cup cover is in contact with the bottom of the module housing.

[0026] The advantages of adopting the above technical solution are that the air outlet on the dust cup cover contacts the bottom of the module housing. Impurities filtered by the dust cup body for the first time enter the HEPA module for further filtration. This arrangement ensures smooth airflow between the dust cup filter module and the HEPA module, making the filtration process more continuous and efficient. The contact between the dust cup cover and the bottom of the module housing also provides a certain degree of sealing, reducing the possibility of air leakage and further improving the performance of the entire filtration system.

[0027] Furthermore, symmetrically arranged sliding plates are provided on both sides of the sliding block, and a moving groove is provided at the corresponding position of the sliding groove for the sliding plate to move, and the sliding plate moves along the moving groove.

[0028] The advantage of adopting the above technical solution is that the symmetrically arranged sliding plates and moving grooves effectively prevent the sliding block from shaking or shifting during movement, ensuring accurate engagement between the protruding head and the groove. This not only improves the reliability of the side cover opening and closing operation but also reduces the problem of the side cover failing to close properly or opening accidentally due to inaccurate sliding block positioning, further enhancing the stability and safety of the dust cup filter module.

[0029] Furthermore, the filter screen is conical.

[0030] The advantages of adopting the above technical solution are that the conical filter screen forms a cyclone guide channel. When dust and air enter the dust cup body, a cyclone is formed under the action of the conical filter screen. This causes larger dust particles to be thrown against the inner wall of the dust cup body under the action of centrifugal force, and then fall naturally to the bottom, achieving preliminary and efficient separation and filtration. This design increases the contact area between air and the filter screen, improves filtration efficiency, and reduces dust accumulation on the filter screen, extending the cleaning cycle and service life of the filter screen.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings.

[0045] like Figure 1-4 As shown, this utility model discloses a handheld vacuum cleaner with an independent and detachable HEPA module, comprising:

[0046] The vacuum cleaner body 1 has a fan 12 installed inside;

[0047] The HEPA module is detachably installed inside the vacuum cleaner body 1 and includes: a module housing 2, a HEPA filter layer 3, and a top cover 4. The HEPA filter layer 3 is installed inside the module housing 2, and the top cover 4 is connected to the module housing 2.

[0048] The dust cup filter module is detachably installed inside the vacuum cleaner body 1, and includes a dust cup body 5, a filter screen 51, and a side cover 52. The filter screen 51 is installed inside the dust cup body 5, and the side cover 52 is connected to the dust cup body 5 and can be opened and closed.

[0049] The advantage of adopting the above technical solution is that, by setting up an independent and detachable HEPA module, users can easily clean or replace the HEPA filter layer 3 without disassembling the entire filtration system, greatly reducing the difficulty of maintenance. Moreover, both the HEPA module and the dust cup filter module are detachable, working independently yet collaboratively to effectively filter dust and impurities of different particle sizes.

[0050] Furthermore, such as Figure 5-6As shown, the bottom of the module housing 2 has multiple air inlets 21, and a bottom cover 22. A ventilation cavity is left between the bottom cover 22 and the module housing 2. The interior of the module housing 2 has a chamber for installing the HEPA filter layer 3, and a protruding side plate 24 is located within the chamber. The side plate 24 is integrally formed with the entire module housing 2. The bottom cover 22 has two protrusions 25, forming a groove between them to fix the side plate 24. During installation, the bottom of the protrusions 25 abuts against the inner wall of the module housing 2, while the side plate 24... Located in the groove between the two protrusions 25, the entire bottom cover 22 cannot rotate. The bottom of the bottom cover 22 is flat, and an installation groove for accommodating the HEPA filter layer 3 is provided on it. The bottom of the HEPA filter layer 3 is located in the installation groove, and the top is limited by the top cover 4, so that the entire HEPA filter layer 3 will not move. In addition, there is a space between the bottom cover 22 and the inner wall of the module housing 2, which plays a role in buffering and diverting air. The airflow enters through the side of the HEPA filter layer 3, and the HEPA filter layer 3 plays a role in high-efficiency filtration.

[0051] Furthermore, the module housing 2 is provided with a snap-fit ​​part 23, and the vacuum cleaner body 1 has an outer shell 6. The outer shell 6 is provided with a mating groove that cooperates with the snap-fit ​​part 23. The entire snap-fit ​​part 23 and the module housing 2 are integrally formed. The cross-section of the snap-fit ​​part 23 is L-shaped. It contacts the mating groove of the outer shell 6 for positioning and fixing. At the same time, the outer shell 6 is provided with a receiving chamber for accommodating the entire module housing 2, so that the module housing 2 can be fixed inside the outer shell 6 and will not rotate due to the snap-fit ​​part 23.

[0052] Furthermore, the upper cover 4 is provided with an air outlet, and a protruding ring 41 is provided along the outer edge of the air outlet. The protruding ring 41 is integrally formed with the upper cover 4. The protruding ring 41 is connected to the fan 12 and is equipped with a sealing ring 42. The upper cover 4 is fastened and fixed to the module housing 2, and a sealing ring is also provided between the upper cover 4 and the module housing 2.

[0053] In some implementations, the vacuum cleaner body 1 has a suction pipe 11, a fan 12, and a handheld part 13. The fan 12 is located on one side of the HEPA module, and the HEPA module has an outlet connected to the fan 12. The dust cup filter module is located between the HEPA module and the suction pipe 11, and is connected to both. The suction pipe 11 is fixedly installed to the outer casing 6.

A conical filter screen 51 is installed inside the dust cup body 5. The filter screen 51 is made of metal and has multiple filter holes for filtration. The outer casing 6 has a notch, allowing the entire dust cup filter module to be removed from the side for easy maintenance. During use, dust and impurities enter the dust cup filter module through the suction pipe 11 for initial filtration, and then enter the HEPA module for secondary filtration. The fan 12 provides suction, allowing air to flow smoothly between the modules, completing an efficient filtration process.

[0054] Furthermore, such as Figure 7-10 As shown, one end of the side cover 52 is hinged to the dust cup body 5. The side cover 52 is provided with a sliding groove 53, and a sliding block 54 is provided in the sliding groove 53. The sliding block 54 is provided with a protruding head 55. The dust cup body 5 is provided with a groove that mates with the protruding head 55. Along the sliding direction of the sliding groove 53, a spring is provided between the upper cover 4 and the sliding block 54. When the sliding block 54 is not driven by external force, the protruding head 55 extends into the dust cup body 5, ensuring the fixation of the side cover 52. When it is necessary to open the side cover 52 to clean internal impurities, only... Slide the sliding block 54 to retract the protruding head 55, so that the entire side cover 52 can be fully opened. After emptying the internal impurities, the side cover 52 can be snapped back on. At the same time, symmetrically arranged and fixedly installed sliding plates 541 are provided on both sides of the sliding block 54. The sliding groove 53 is provided with a moving groove for the sliding plate 541 to move. The sliding plate 541 moves along the moving groove. The sliding groove 53 and the moving groove limit the position of the sliding block 54 to prevent accidental opening or incomplete closing, and facilitate the cleaning of the inside of the dust cup body 5.

[0055] Furthermore, a sealing ring is provided between the side cover 52 and the dust cup body 5. This sealing ring ensures the sealing performance of the dust cup body 5, preventing dust and debris from leaking out from the connection point during use. This avoids secondary pollution to the surrounding environment and ensures stable air pressure inside the dust cup filter module, making the filtration process more efficient. Simultaneously, the sealing ring also acts as a buffer and shock absorber, reducing wear and tear on the side cover 52 and dust cup body 5 during frequent opening and closing, thus extending their service life.

[0056] Furthermore, a protruding block 56 is provided at the bottom of the dust cup body 5, and a rotating block 7 is installed on the vacuum cleaner body 1. The rotating block 7 has integrally formed rotating protruding shafts on both sides. The outer shell 6 has a mounting position for the rotating block 7.

A sealing ring is installed at the air outlet, which contacts the bottom of the module housing 2 to ensure the sealing between the dust cup body 5 and the module housing 2. After the first filtration by the dust cup body 5, the gas enters the HEPA module for further filtration, reducing the possibility of air leakage and ensuring filtration performance.

[0058] Furthermore, the vacuum cleaner body 1 is equipped with a switch assembly for controlling the vacuum cleaner to be turned on and off.

[0059] The advantages of this invention lie in the independently detachable HEPA module and dust cup filter module, which not only provides users with a convenient maintenance method but also greatly improves the overall performance and lifespan of the vacuum cleaner. In daily use, users can flexibly clean or replace these two modules according to the actual dust accumulation. For the HEPA module, due to its high-efficiency filtration capacity, it may accumulate a large number of fine particles after prolonged use. In this case, users can easily remove it from the vacuum cleaner body 1, clean the HEPA filter layer 3, or directly replace it with a new filter layer to quickly restore its excellent filtration effect. The dust cup filter module plays an important role in collecting larger dust particles. The dust inside can be easily emptied by opening the side cover 52. When it is difficult to empty completely, the entire dust cup body 5 can be disassembled for thorough cleaning, ensuring that the dust cup filter module always maintains a good working condition.

[0060] Furthermore, this independent and detachable design makes vacuum cleaner maintenance more convenient. Moreover, the connections between the various modules are tight and well-designed, and the multiple sealing rings further enhance the overall system's sealing performance, reducing air leakage and noise generation, creating a quiet and efficient operating environment for users.

[0061] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
