Example
[0040] See Figures 1-5As shown, a cylindrical air purifier has a compact and efficient structure, including a base 1 with a side-wall grid structure, which ensures air circulation and enhances aesthetics. A shell 2 is mounted on the base 1, forming a unified appearance. A partition 3 is installed inside the shell 2, dividing the interior of the shell 2 into an upper chamber and a lower chamber. A grid 31 is opened in the middle of the partition 3 to allow air circulation between the upper and lower chambers. A purification component 4, covering the grid on the partition 3, is installed in the lower chamber, effectively filtering impurities and harmful substances from the air. An air duct 5, also covering the grid on the partition 3, is installed in the upper chamber, and a fan assembly 6 is installed inside the air duct 5. The motor mount 61 of the fan assembly 6 is firmly fixed to the air duct 5, ensuring operational stability. An air outlet assembly 7 is installed on the motor mount 61. The air outlet assembly 7 consists of an air outlet mesh 71 and an air outlet frame 72. The air outlet mesh 71 is nested inside the air outlet frame 72, ensuring uniform and safe airflow. Notably, the air outlet frame 72 is not only fixed to the motor mount 61, but also cleverly incorporates the control component 8. The housing of the control component 8 is suspended above the air outlet mesh 71, with both ends fastened to the air outlet frame 72, forming a handle structure that facilitates handling. This design not only improves the ease of operation but also optimizes the aesthetics of the overall structure.
[0041] In this embodiment, the purification component 4 is meticulously and practically constructed. It uses a filter screen 41 as its core component to effectively filter impurities in the air. An upper filter screen cover 42 is located above the filter screen 41, while a lower filter screen cover 43 is located below it. This design not only protects the filter screen 41 but also enhances its stability. During installation, when the base 1 is fixed to the outer casing 2, the lower filter screen cover 43 fits tightly against the base 1, while the upper filter screen cover 42 firmly abuts against the partition 3, completely covering the mesh 31 on the partition 3. This ensures that the air is fully purified by the filter screen 41 before entering the upper chamber.
[0042] Furthermore, the grid 31 on the partition 3 features a unique design, with a protruding side facing the lower chamber. This design facilitates the secure mounting of the upper filter cover 42 onto the grid, enhancing structural stability. Simultaneously, both the upper and lower filter covers 42 and 43 are cleverly equipped with slots for precise positioning and securing of the filter 41, ensuring it does not shift during operation. Notably, the filter 41 is available in a variety of types; depending on the specific application, a pre-filter, HEPA filter, activated carbon filter, or negative ion filter can be selected to meet the air purification needs of different scenarios.
[0043] In this embodiment, a convenient snap-fit fixing method is adopted between the base 1 and the outer shell 2. Specifically, the upper end of the base 1 is cleverly designed with a positioning buckle 11 and a pressing buckle 12, which are symmetrically distributed at 180 degrees to ensure the stability and balance of the fixing. Correspondingly, the outer shell 2 is provided with a slot and a notch. The slot is used to receive one end of the positioning buckle 11, while the notch allows part of the pressing buckle 12 to be exposed for easy operation. In use, the user only needs to align one end of the positioning buckle 11 with the slot, and then press down the pressing buckle 12 so that its upper end is embedded into the outer shell 2 above the notch, which can easily achieve a firm fixation between the base 1 and the outer shell 2. When it is necessary to replace the filter 41, it is also only necessary to press down the pressing buckle 12 to easily remove the base 1. The whole operation process is simple and quick, greatly improving the convenience of filter replacement.
[0044] In this embodiment, the fan assembly 6 includes a motor mount 61, on which a centrifugal fan 62 is securely mounted, facing downwards. A turbine fan 63 is mounted on the centrifugal fan 62. This design effectively utilizes space and optimizes the airflow path. Specifically, a motor mounting cover 64 is specially designed above the centrifugal fan 62 to ensure the stability of the fan installation. Furthermore, to enhance protection, a motor cover is added to the motor mounting cover 64. This cover not only serves an aesthetic purpose but, more importantly, effectively blocks external dust, protecting the centrifugal fan 62 from damage and extending its service life.
[0045] Furthermore, the turbine fan blades feature an inlaid design, ensuring a tight fit between the blades and the fan body, thus improving overall stability and durability. Each blade incorporates a rotating bending structure, a design that allows the blade's curvature to effectively concentrate airflow during rotation, resulting in excellent airflow circulation performance. Additionally, the number of blades is set to an odd number to maintain the balance of the entire fan system.
[0046] In this embodiment, the control component 8 has a compact housing structure, consisting of a control base 81, a light shield 82, and a control panel 83, effectively protecting the internal components. The housing houses a control board 84, responsible for core control functions. The control panel 83 and the control board 84 are electrically connected, enabling precise transmission of user commands and device response.
[0047] In this embodiment, a junction box 9 is connected below the partition 3. The junction box 9 has a cable routing channel that runs through the top of the partition 3, facilitating cable routing. The junction box 9 has a built-in power supply unit, which serves as the core of the power supply for the cylindrical air purifier, ensuring stable operation of the device. A power indicator light is provided on the outer casing 2, which is electrically connected to the control board 84 to display the operating status of the cylindrical air purifier.
[0048] In this embodiment, the layout design of the line box 9 cleverly integrates a Hall switch 91 electrically connected to the control board 84, in addition to the power supply unit. This design utilizes the principle of magnetic induction: the base 1 has a built-in magnet 92. When the base 1 is correctly installed on the outer casing 2, the Hall switch 91 can accurately sense the magnetic field of the magnet 92, thereby confirming the stable connection of the base 1; once the base 1 is removed, the Hall switch 91 loses its sensing function. This mechanism effectively monitors the installation status of the base 1.
[0049] In addition, to further enhance the safety of the cylindrical air purifier, the design team also introduced a tilt switch, which is also electrically connected to the control board 84. When the cylindrical air purifier accidentally falls, the tilt switch responds immediately, automatically cutting off the power supply to ensure that the device does not operate under abnormal conditions, preventing potential damage or safety hazards.
[0050] Meanwhile, to intelligently manage the cleaning needs of the cylindrical air purifier, a dust sensor is added to the outside of the air duct 5, which is connected to the control board 84. When the dust concentration in the air reaches a preset threshold, the dust sensor sends a signal to the control board, reminding the user that too much dust may have accumulated inside the cylindrical air purifier and needs to be cleaned in time, thereby maintaining the purification effect and the long-term stable operation of the equipment.
[0051] In this embodiment, multiple foot pads 10 are cleverly arranged on the lower end surface of the base 1. These foot pads 10 are evenly distributed along the circumference, which not only enhances stability but also effectively reduces friction and noise with the placement surface.
[0052] The cylindrical air purifier provided by this utility model exhibits excellent performance indicators, fully meeting users' dual needs for efficient purification and a comfortable experience. Its main technical specifications are as follows:
[0053] In terms of airflow, this cylindrical air purifier offers a wide range of adjustment, with a maximum airflow of 235.9 CFM (cubic feet per minute), which can quickly remove pollutants from indoor air; while in the minimum airflow mode, there is a stable output of 109.7 CFM, ensuring continuous air circulation while reducing energy consumption and noise.
