They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 This utility model discloses a magnetically mounted air purifier, including a housing 100, an inlet filter assembly 300, a fan module 400, an outlet filter assembly 500, and a sensing element 700. The housing 100 includes a front shell 110 and a rear cover 120, with the rear cover 120 detachably connected to the rear end of the front shell 110 to close it. The inlet filter assembly 300 is slidably connected to the lower end of the front shell 110 in the front-to-back direction. The fan module 400 is disposed in the front shell 110 and above the inlet filter assembly 300, and is used to draw air from bottom to top through the inlet filter assembly 300. The outlet filter assembly 500 is slidably connected to the front shell 110 in the front-to-back direction. In the front housing 110, the outlet air filter assembly 500 is positioned above the fan module 400. The outlet air filter assembly 500 receives the air output from the fan module 400. Three sensing elements 700 are provided, all located on the front housing 110. Triggers 800 are provided on the rear cover 120, the inlet air filter assembly 300, and the outlet air filter assembly 500. Each sensing element 700 corresponds to a trigger 800. All three sensing elements 700 are electrically connected to the fan module 400. When any trigger 800 in the rear cover 120, the inlet air filter assembly 300, or the outlet air filter assembly 500 leaves its corresponding sensing element 700, the fan module 400 stops operating. It is understandable that this electrical connection is a conventional electrical connection method. To achieve the control effect, it is necessary to electrically connect to common circuit boards, chips, or PLC controllers, etc.

[0023] It has at least the following beneficial effects: The sensing element 700 and the trigger 800 form a protection device. When the machine is disassembled, when any of the triggers 800 in the rear cover 120, the inlet air filter assembly 300 and the outlet air filter assembly 500 leaves the corresponding sensing element 700, the fan module 400 stops operating, thereby protecting the operator from being injured by the fan and achieving the protection function when the filter assembly or the rear cover 120 is opened.

[0024] In some embodiments, an air outlet cover 200 is also included. The air outlet cover 200 is connected to the upper end of the housing 100.

The air outlet filter assembly 500 extends into the air outlet cover 200.

[0025] In some embodiments, the bottom air inlet of the air outlet filter assembly 500 covers the air outlet of the fan module 400, and air can be discharged from the top and all sides of the air outlet filter assembly 500.

[0026] In some embodiments, the sensing element 700 is a Hall element, the trigger element 800 is a magnetic block, and the Hall element is electrically connected to the fan module 400. It is understood that the bottom air inlet of the outlet filter assembly 500 covers the air outlet of the fan module 400, ensuring that the air discharged from the fan module 400 can completely enter the outlet filter assembly 500, preventing air leakage and thus avoiding poor filtration.

[0027] In some embodiments, the air inlet filter assembly 300 includes an air inlet seat 310 and a first filter element 320. The air inlet seat 310 is installed in the housing 100, with an open lower end and an air guide nozzle 311 at the upper end. The first filter element 320 is detachably installed in the air inlet seat 310, with the lower end of the air inlet seat 310 connected to the lower end of the first filter element 320, and the lower end of the air guide nozzle 311 connected to the upper end of the first filter element 320. The upper end of the air guide nozzle 311 is connected to the ventilation fan module 400. It is understood that "open" means that the lower end of the air inlet seat 310 is completely open, allowing the lower end of the first filter element 320 to be fully exposed to the air, enabling air to pass completely through the lower end of the first filter element 320.

[0028] In some embodiments, a first screen 312 is provided inside the air inlet seat 310. The first screen 312 is disposed between the upper end of the first filter element 320 and the lower end of the air guide nozzle 311. The first screen 312 is used to isolate dust.

The fan 420 is disposed in the first channel 411. The lower end of the mounting housing 410 is used to connect to the air guide nozzle 311. The upper end of the mounting housing 410 is connected to a second partition 412. The upper end of the mounting housing 410 is connected to the air outlet filter assembly 500.

[0030] In some embodiments, the air outlet filter assembly 500 includes an air outlet seat 510 and a second filter element 520. The second filter element 520 is installed in the air outlet seat 510. The air outlet seat 510 is detachably connected to the upper end of the mounting housing 410. The top and all sides of the air outlet seat 510 are provided with second air outlets (not shown in the figure). The second filter element 520 is used to receive the air output from the fan 420.

[0032] In some embodiments, the first filter element 320 includes a support frame 321 and a filter membrane 322. The support frame 321 is provided with a second channel 321a extending vertically. Both the upper and lower openings of the second channel 321a are connected to the filter membranes 322. The space between the two filter membranes 322 is used to load a filter medium. The support frame 321 is detachably installed in the air inlet seat 310. It is understood that the filter medium includes activated carbon or similar materials used for filtering air.

[0033] In some embodiments, both the air outlet seat 510 and the second filter element 520 are cylindrical bodies, with the lower end of the air outlet seat 510 and the lower end of the second filter element 520 being open, and the second filter element 520 being fitted and installed on the inner peripheral wall of the air outlet seat 510.

[0034] In some embodiments, the system further includes a base 600, which is connected to the lower end of the housing 100. The base 600 has a through-hole 610 in the middle, which is connected to the air intake filter assembly 300. At least three rollers 620 are provided on the base 600.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
