Description

Technical Field

[0001] This utility model relates to the field of nail vacuuming equipment, and more particularly to a nail vacuum cleaner. Background Technology

[0002] Manicures have become a common beauty procedure in modern life, but the process of filing nails generates a large amount of extremely fine dust. This dust is lightweight and easily dispersed, not only polluting the environment but also potentially being inhaled by both the manicurist and the customer, affecting their health. Therefore, manicure vacuum cleaners, which can efficiently collect this fine dust at its source, have become an indispensable piece of professional equipment in nail salons.

[0003] Currently, most nail vacuum cleaners on the market use a direct suction method. Their typical structure includes a main unit with a built-in motor and a dustbin for collecting dust. Dust-laden air is drawn in through the air inlet, usually passes through a simple filter, and then directly enters the dustbin area, where the motor expels the air. In this design, the motor's air intake is directly or indirectly connected to the airflow environment inside the dustbin.

[0004] However, some problems remain. Due to the lack of efficient primary separation methods, the fine dust generated by nail salons can easily penetrate simple filter structures or be re-entrained by airflow within the dust chamber, eventually entering the motor. This not only leads to reduced suction power but can also cause motor blockage, overheating, or even damage, severely impacting the equipment's lifespan and reliability. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by using an integrated separator cluster for multi-stage centrifugal separation, effectively capturing fine dust, fundamentally preventing motor blockage, extending equipment life, and facilitating cleaning.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution that prevents fine dust from clogging the motor during nail filing, thereby extending its service life.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A nail vacuum cleaner includes a main unit and a motor installed inside the main unit, and a dust chamber assembly detachably connected to the main unit. The dust chamber assembly has an air inlet and an air outlet, the air outlet being connected to the air inlet of the main unit. The dust chamber assembly has at least one centrifugal separation device inside, the centrifugal separation device being an integrated separator cluster composed of several separation units arranged circumferentially. Each separation unit is configured to generate rotational centrifugal force by tangentially entering the airflow. The bottom of the integrated separator cluster has a dust collection chamber for collecting the separated dust.

[0008] Preferably, the separation unit is a cyclone separation unit with a tangential inlet and a central exhaust port.

[0009] Preferably, the centrifugal separation device is configured in multiple stages, including a first separator cluster as the first stage and a second separator cluster as the second stage.

[0010] Preferably, the air inlet of the second separator cluster is connected to the air inlet of the dust bin assembly, and the air inlet of the first separator cluster is connected to the exhaust port of the second separator cluster.

[0011] Preferably, the bottom ash discharge ports of the first separator cluster and the second separator cluster are connected to the dust collection bin.

[0012] Preferably, the dust collection bin is detachably connected to the bottom of the dust bin assembly.

[0013] Preferably, the dust collection assembly is further provided with a filtration mechanism located downstream of the airflow of the centrifugal separator.

[0014] Preferably, the filtration mechanism includes a first filtration structure and a second filtration structure, wherein the first filtration structure is disposed above the exhaust gas of the integrated separator cluster, and the second filtration structure is disposed in the airflow channel downstream of the first filtration structure.

[0015] Preferably, the air inlet of the dust bin assembly is connected to an air inlet channel, and the outer periphery of the air inlet channel is provided with a noise reduction structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The nail vacuum cleaner provided in this application, through the setting of an integrated separator cluster composed of several circumferentially arranged separation units, allows the dust-laden airflow to enter tangentially, generating high-speed rotating centrifugal force. This efficiently separates and collects most of the fine dust generated during the nail process into the bottom dust collection bin before it enters the motor. This fundamentally avoids the problem of fine dust directly penetrating and clogging the motor, significantly improving separation efficiency and equipment reliability, while also solving the core problem of motor damage.

[0024] Example: Please see Figure 1-5A nail vacuum cleaner includes a main unit 1 and a motor 11 installed inside the main unit 1. It also includes a dust chamber assembly 2 detachably connected to the main unit 1. The dust chamber assembly 2 has an air inlet 3 and an air outlet 8. The air outlet 8 is connected to the air inlet of the main unit 1. The dust chamber assembly 2 has at least one centrifugal separation device 4 inside. The centrifugal separation device 4 is an integrated separator cluster formed by several separation units arranged circumferentially. Each separation unit is configured to generate rotational centrifugal force by tangentially entering the airflow. The bottom of the integrated separator cluster has a dust collection chamber 5 for collecting the separated dust.

[0025] This nail vacuum cleaner mainly consists of two parts: the main unit 1 and the dust collection assembly 2. Its core function is to capture most of the dust before it reaches the motor 11 through a highly efficient, integrated multi-stage centrifugal separation system. The dust collection assembly 2 is detachably connected to the main unit 1 via snap-fit ​​mechanisms, facilitating overall cleaning and maintenance. The dust collection assembly 2 forms the core cavity for separation and filtration. It has an air inlet 3 at its top, connected to a suction pipe (not shown in the diagram), to draw in dust-laden air. The air inlet 3 is connected to an air intake channel 31, the outer periphery of which is wrapped with noise-reducing structures 311, such as sound-absorbing cotton, to reduce noise generated when airflow enters.

[0026] The dust collection assembly 2 has a centrifugal separation device 4 located at its center. This centrifugal separation device 4 is multi-stage, specifically including a second separator cluster 42 as the first stage and a first separator cluster 41 as the second stage. The naming follows the airflow sequence, with the first stage being the first and the last stage the second. Both the first separator cluster 41 and the second separator cluster 42 are integrated, cone-shaped structures formed by circumferentially arranged cyclone separation units. Each cyclone separation unit has an independent tangential inlet and a central exhaust port. This design significantly increases the contact area and efficiency of centrifugal separation within a limited space.

[0027] It should also be noted that, in actual practical use, the outermost layer of the centrifugal separation device 4 can be covered with a filter screen.

[0028] The air inlet of the second separator cluster 42 is directly connected to the air inlet 3 of the dust collection assembly 2, forming the first stage of separation. The air inlet of the first separator cluster 41 is connected to the central exhaust port of the second separator cluster 42, forming the second stage of separation. The bottom dust discharge ports of the first separator cluster 41 and the second separator cluster 42 are connected to a dust collection chamber 5. This dust collection chamber 5 is detachably connected to the bottom of the dust collection assembly 2 and is specifically used to collect most of the nail dust separated from the two-stage separator clusters.

[0029] After fine separation by the centrifugal separator 4, the airflow enters the filtration stage. Above the exhaust of the first separator cluster 41, a first filter structure 6, such as a pre-filter, is provided to intercept extremely fine dust that was not completely collected in the separator. Subsequently, the airflow continues to the second filter structure 7, which is located in the airflow channel downstream of the first filter structure 6. This second filter structure 7 can be a HEPA filter, serving as the final protection to ensure that any micron-sized particles that may escape are captured. The clean air filtered by the second filter structure 7 collects in the bottom cavity of the dust collection assembly 2.

[0030] The bottom side wall of the dust collection assembly 2 is provided with an air outlet 8. This air outlet 8 is connected to the air inlet of the main unit 1. The upper layer of the main unit 1 is equipped with a motor 11, including a fan, and its air inlet is located on the lower layer. The main unit 1 can be designed with a specific bypass channel, which can be filled with noise-reducing materials such as sound-absorbing cotton. The clean airflow from the air outlet 8 enters the main unit 1, passes through the bypass channel to the air inlet of the motor 11, is drawn in by the fan, and is finally discharged from the exhaust port on the side of the main unit 1. This design not only forms a closed-loop airflow during operation, but also effectively reduces the overall operating noise of the machine by increasing the length of the flow channel and filling it with noise-reducing materials.

[0031] Working principle Inhalation and initial noise reduction: Dust-laden air is drawn in from the air inlet 3 and first passes through the air inlet channel 31, which is wrapped with a noise reduction structure 311, achieving initial noise reduction as it enters the dust bin assembly 2.

[0032] In the first stage of centrifugal separation, the airflow first enters the second separator cluster 42, which serves as the first stage. Within each cyclone separator unit, the airflow enters tangentially, generating high-speed rotation. Larger dust particles are thrown against the wall under centrifugal force and fall along the conical wall, eventually entering the dust collection bin 5 through the bottom ash discharge port. In the second stage of centrifugal separation, the airflow after the first stage separation, carrying finer dust, rises from the central exhaust port of the second separator cluster 42 and enters the first separator cluster 41, which serves as the second stage. Here, a more intense secondary centrifugal separation occurs, further separating fine dust particles, which also fall into the dust collection bin 5.

[0033] After two stages of centrifugal separation, the remaining fine dust particles in the air rise with the airflow and are intercepted by the first filter structure 6 after passing through the central exhaust port at the top of the first separator cluster 41. The airflow then continues through the first filter structure 6 and undergoes final filtration by the second filter structure 7. At this point, most of the dust in the air has been removed. The clean air gathers at the bottom of the dust collection assembly 2 and enters the main unit 1 from the bottom exhaust port 8. It flows through a bypass channel filled with noise-reducing material, is drawn in by the fan driven by the motor 11, and finally exits from the exhaust port on the side of the main unit 1, completing the entire dust collection process.

[0034] In summary, the combination of two-stage integrated centrifugal separation and two-stage filtration solves the problem of fine nail dust clogging the motor 11. At the same time, the modular and detachable dust chamber component 2 and the dust collection chamber 5 greatly facilitate cleaning and maintenance for users, significantly improving the product's lifespan and user experience.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
