Description

Technical Field

[0001] This invention belongs to the field of vacuum cleaner technology, and particularly relates to a handheld anti-tangling vacuum cleaner. Background Technology

[0002] Handheld vacuum cleaners are favored for their excellent portability and ease of use. They excel at cleaning in many small spaces in the home, such as cabinet crevices, sofa corners, and car interiors and under seats. These devices efficiently remove accumulated dust, small food crumbs, pet hair, and other loose debris, significantly improving the efficiency and convenience of daily cleaning. Currently, the core structure of handheld vacuum cleaners typically includes the main body, a cyclone separator for initial filtration, a suction motor for power, a battery module for long-lasting power, and various cleaning heads designed for different cleaning scenarios. When the device is started, the built-in suction motor quickly operates, generating a strong negative pressure airflow; this airflow powerfully sucks in debris mixed with dust from the nozzle, first entering the transparent dust cup. Subsequently, the air-solid mixture is directed to a precision-designed cyclone separator, where the crucial air-dust separation process is completed: heavier dust particles are thrown to the cup wall by centrifugal force and eventually settle at the bottom of the dust cup, while the purified clean air is safely discharged from the equipment through the filtration system, thus ensuring that the cleaning process is both efficient and environmentally friendly.

[0003] Currently available handheld vacuum cleaners generally face a significant technical challenge when cleaning environments containing long hair or pet fur: severe hair entanglement. This problem mainly manifests in two core mechanical components:

[0004] 1. Hair entanglement in the roller brush (dust roller): When the roller brush inside the cleaning head rotates, long hair and threads are easily entangled on the surface of the roller and at the base of the bristles, which hinders the normal rotation of the roller brush and reduces cleaning efficiency. Entangled hair needs to be manually removed with scissors or other tools, which is cumbersome and can easily damage the roller brush, making cleaning difficult.

[0005] 2. Separator / Filter Clogging: When airflow containing hair enters the dust cup, the hair easily gets tangled around the metal filter screen of the separator or the cyclone separator cone. Long-term use will clog the mesh, leading to increased wind resistance, decreased suction power, and dust accumulation, further reducing the efficiency of air-dust separation and affecting the overall cleaning effect of the machine. Moreover, the hair tangled on the filter / cone surface is difficult to clean completely. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a handheld anti-tangling vacuum cleaner to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a handheld anti-tangling vacuum cleaner, comprising...

[0008] The housing has an air inlet on its side;

[0009] A dust cup is installed inside the housing and connected to the air inlet to introduce gas containing impurities into the dust cup.

[0011] A baffle plate is located inside the dust cup and has a gap between it and the cyclone cone. The baffle plate includes a main plate and a sub plate. The main plate is vertically installed at the bottom of the dust cup. The sub plate is integrally formed with the main plate and is arranged parallel to the bottom surface of the dust cup. A vortex zone is formed on the baffle plate. After slender impurities are agglomerated on the cyclone cone, they enter and are stored in the vortex zone with the airflow.

[0012] A negative pressure fan is located inside the housing and, after generating negative pressure, guides gas into the dust cup through the air inlet.

[0013] A power source, located inside the housing and connected to the negative pressure fan.

[0014] In a preferred embodiment of the present invention, a filter cotton is provided inside the housing, and the filter cotton is located above the dust cup to perform secondary filtration on the gas after preliminary filtration.

[0015] In a preferred embodiment of the present invention, the housing is provided with an air outlet, which corresponds to the position of the filter cotton, so as to discharge the gas filtered in the second stage.

[0016] In a preferred embodiment of the present invention, the dust cup includes an upper cover and a lower cover, the upper cover and the lower cover are detachably connected, the cyclone cone is located inside the upper cover, and the baffle is installed on the lower cover. When the lower cover and the upper cover are closed, the baffle enters the interior of the dust cup.

[0017] In a preferred embodiment of the present invention, the bottom of the upper cover is provided with a side notch to increase the gas flow area and introduce more gas into the cyclone cone.

[0018] In a preferred embodiment of the present invention, the sub-plate is provided with a plurality of air holes to rapidly return gas to the cyclone cone.

[0020] In a preferred embodiment of the present invention, a protrusion is formed on the motherboard to block impurities and slow down the airflow.

[0021] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0022] This invention relates to a handheld anti-tangling vacuum cleaner, which incorporates a baffle structure with a main plate and a secondary plate inside its dust cup. Through precise geometric design, this baffle creates a stable and continuous vortex zone within the dust cup. The presence of the baffle allows for the effective pre-trapping of hair that has clumped together on the cyclone cone surface under the influence of high-speed rotating airflow and subsequently detached, thus preventing this hair from re-entering the cyclone cone surface and becoming entangled again. This solves the core problem in traditional cyclone vacuum cleaners where the cyclone cone is easily blocked by hair entanglement and accumulation, leading to a significant increase in air resistance and a rapid decrease in overall suction power.

[0023] Meanwhile, this design concentrates and stores trapped hair within the formed stable vortex zone. When the user needs to clean the dust cup, they can simply open the easily removable bottom cover to remove the accumulated hair clumps from the vortex zone in one go. This design completely changes the traditional cleaning method; users no longer need to laboriously peel off the hair tightly wrapped around the cyclone cone surface, greatly simplifying the maintenance process and shortening cleaning time. Therefore, it not only significantly improves the daily user experience and maintenance convenience of the product, but more importantly, in the long run, it ensures the long-term stability of the vacuum cleaner's suction performance and the efficient and reliable operation of the air-dust separation system, thus maintaining the excellent performance of the entire machine.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0032] This embodiment of the handheld anti-tangling vacuum cleaner incorporates a baffle 40 structure with a main board 41 and a secondary board 42 inside its dust cup 20. Through precise geometric design, the baffle 40 forms a stable and continuous vortex zone 70 within the dust cup 20. The presence of the baffle 40 effectively traps hair that has tangled on the surface of the cyclone cone 30 under the influence of high-speed rotating airflow and subsequently detached, preventing this hair from re-entering the cyclone cone 30 and becoming tangled again. This solves the core problem in traditional cyclone vacuum cleaners where the cyclone cone 30 is easily blocked by hair tangling and accumulation, leading to a significant increase in air resistance and a rapid decrease in overall suction power. This design concentrates the trapped hair within the formed stable vortex zone 70. When the user needs to clean the dust cup 20, they can easily open the detachable bottom cover 202 at the bottom of the dust cup 20 to remove the accumulated hair clumps from the vortex zone 70 in one go. This design completely revolutionizes traditional cleaning methods. Users no longer need to painstakingly peel hair tightly tangled on the cyclone cone 30, greatly simplifying the maintenance process and shortening cleaning time. Therefore, it not only significantly improves the daily user experience and maintenance convenience of the product, but more importantly, in the long run, it ensures the long-term stability of the vacuum cleaner's suction performance and the efficient and reliable operation of the air-dust separation system, thus maintaining the excellent performance of the entire machine.

[0033] Combination Figures 1 to 5 As shown, this embodiment specifically provides a handheld anti-tangling vacuum cleaner. The vacuum cleaner includes a housing 10 that serves as the main support structure. An air inlet 11 is provided on the side wall of the housing 10, which functions as an airflow channel, allowing external airflow mixed with dust, hair, and other impurities to enter the internal space of the device.

[0034] Inside the housing 10, there is a key separation container—dust cup 20. The dust cup 20 is connected to the air inlet 11. Its core function is to guide the airflow containing various impurities drawn in through the air inlet 11 directly into the cavity of the dust cup 20, where the separation operation between gaseous air and solid dust and impurities is performed.

[0035] Furthermore, a cyclone cone 30 is installed inside the dust cup 20. When the gas containing impurities enters the dust cup 20, it first flows through this cyclone cone 30. With the strong centrifugal force generated by the cone, the airflow can complete the first stage of filtration and separation. In this process, larger dust impurities with coarser particle size, as well as substances such as hair that are prone to entanglement, can be effectively thrown off the airflow and initially separated.

[0036] To optimize the subsequent collection of slender impurities (especially hair), this embodiment adds a baffle 40 inside the dust cup 20. The baffle 40 is positioned within the dust cup 20, with a certain physical gap maintained between it and the cyclone cone 30. This design ensures that its presence does not interfere with or hinder the cyclone cone 30 from performing its centrifugal separation function. Structurally, the baffle 40 is formed by integrating a main plate 41 and a secondary plate 42 using a one-piece molding process. The main plate 41 is vertically oriented, with its bottom end fixedly connected to the bottom inner wall of the dust cup 20; while the secondary plate 42 maintains a generally parallel orientation to the bottom surface of the dust cup 20. Due to the presence of the baffle 40, a relatively aerodynamically stable low-pressure vortex zone 70 can be formed in the corresponding area inside the dust cup 20. Those fine, hair-like impurities that clump together on the surface of the cyclone cone 30 and eventually fall off will be drawn into and stored in this specific vortex zone 70 by the continuous driving of the subsequent airflow, thus effectively preventing them from entangled in other parts of the airflow channel.

[0037] The core component that provides continuous power for the entire vacuuming process is the negative pressure fan 50, which is also installed inside the housing 10. When it is working, it can generate a stable and powerful negative pressure suction. It is this suction that drives the outside air to continuously flow in through the air inlet 11 and continuously introduces the gas containing impurities into the dust cup 20 for treatment.

[0038] Finally, the entire device is powered by a power supply 60 located inside the housing 10. This power supply 60 is electrically connected to the negative pressure fan 50 via wires, and is responsible for supplying the necessary electrical energy for the continuous and stable operation of the negative pressure fan 50, thereby ensuring the normal functioning of all the vacuum cleaner's functions.

[0039] In this embodiment, a filter cotton 80 specifically designed for secondary filtration is installed inside the vacuum cleaner housing 10. This filter cotton 80 is positioned directly above the dust cup 20, and its core function is to receive the dust-laden gas after the first preliminary filtration by the cyclone cone 30. When the airflow carrying residual fine dust that has not yet been completely separated rises, it passes directly through this filter cotton 80. The filter cotton 80, with its dense fiber structure, performs a second stage of fine filtration on the gas, effectively intercepting and adsorbing various fine particles and dust impurities remaining in the airflow. Through this deep purification, the pollutant content in the exhaust gas is significantly reduced, thereby greatly improving the overall cleanliness and freshness of the final exhaust air.

[0040] To ensure the smooth discharge of filtered air, an air outlet 12 is provided at the location of the housing 10 corresponding to the installation area of ​​the filter cotton 80. The clean air, after being thoroughly purified twice by the filter cotton 80, can be smoothly discharged to the external environment of the equipment through this air outlet 12. Thus, the gas flow path in the entire dust collection process—from the intake of dust-laden air, through cyclone separation and adsorption by the filter cotton 80, to the final discharge of clean air—forms a complete, efficient, and closed air circulation system, ensuring the continuous and stable operation of the equipment and its excellent dust removal effect.

[0041] In this embodiment, the dust cup 20 consists of two independent parts: an upper cover 201 and a lower cover 202 that match each other. The upper cover 201 and lower cover 202 are assembled using a convenient detachable connection method. This design fully considers user experience, allowing users to easily open the interior of the dust cup 20 when cleaning accumulated impurities, enabling convenient maintenance and cleaning. Specifically, the cyclone cone 30 is precisely installed and fixed in the internal space of the upper cover 201 of the dust cup 20, while the corresponding baffle 40 is pre-configured and installed on the lower cover 202. When the user aligns and closes the lower cover 202 and upper cover 201, the baffle 40 precisely extends into the internal chamber of the dust cup 20 and accurately reaches the preset position where it is in optimal working condition.

[0042] In this embodiment, the bottom structure of the upper cover 201 features a uniquely designed side notch 2011. The main function of this side notch 2011 is to effectively expand the cross-sectional area of ​​the airflow channel at the bottom of the cyclone cone 30, allowing more airflow carrying impurities to be smoothly introduced into the core space of the cyclone cone 30. This improvement significantly enhances the overall efficiency of the air-dust separation process and strengthens the separation effect. Furthermore, the sub-plate 42 is systematically provided with several air holes 421. When the airflow enters the vortex action area, it can quickly flow back into the internal circulation of the cyclone cone 30 through these evenly distributed air holes 421. This return flow mechanism helps maintain the continuous and stable flow of the entire airflow channel, effectively avoiding the additional wind resistance increase that may be caused by the installation of the spoiler 40, thereby ensuring aerodynamic efficiency and guaranteeing the stability and high efficiency of the overall performance of the vacuum cleaner.

[0043] In this embodiment, the main plate 41 of the spoiler 40 is precisely arranged along the center line of the secondary plate 42, thereby clearly dividing the area below the secondary plate 42 into two relatively distributed and independent spaces—the first region and the second region. This symmetrical distribution pattern makes the overall structure more stable. Regardless of whether the vortex region 70 is ultimately formed in the first region or the second region, it can maintain dynamic balance with the support of the symmetrical layout, effectively ensuring the continuous stability of the vortex during operation.

[0044] Furthermore, the surface of the motherboard 41 is also formed with protrusions 411, which play a crucial guiding and blocking role in the airflow channel. On the one hand, they can effectively intercept various impurities flowing with the airflow, preventing impurities from directly entering the core area; on the other hand, the protrusions 411 change the airflow path, forming a buffer locally, thereby significantly reducing the speed of the airflow. This slowdown in flow velocity creates favorable conditions for substances such as hair to gather, entangle, and form clumps in the airflow, making it easier for the clumped hair to detach from the airflow under gravity and fall into the vortex zone 70, where it is stably trapped. This design further enhances the capture efficiency of hair and similar impurities, improving the overall trapping effect.

[0045] In actual use, when the handheld anti-tangling vacuum cleaner of this embodiment is drawn into the dust cup 20 by the negative pressure fan 50, it first undergoes preliminary centrifugal separation through the cyclone cone 30. Most of the hair will clump together under the action of centrifugal force and then detach from the surface of the cyclone cone 30, flowing down the dust cup 20 with the airflow. At this time, the protrusion 411 of the baffle 40 first slows down the airflow and blocks the hair clump. After the airflow flows along the structure, a stable vortex zone 70 is formed in the preset area. The hair clump is trapped and stored in the vortex zone 70. The remaining airflow flows back to the cyclone cone 30 through the air hole 421 of the sub-plate 42. After preliminary filtration by the cyclone cone 30, it is filtered upwards through the filter cotton 80 for secondary filtration. Finally, the clean air is discharged from the air outlet 12. Throughout the entire working process, hair will not become tangled or blocked again, and airflow will always be unobstructed. This maintains stable suction power. When cleaning, simply open the lower cover 202 to directly remove the complete hair clumps accumulated in the vortex zone 70. There is no need to additionally peel the hair tangled on the cyclone cone 30, making cleaning convenient and efficient.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
