Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and in particular to a small cooling fan that can filter impurities. Background Technology

[0002] Cooling fans are a type of atomizing fans. With their integrated spray function, atomizing fans have a cooling effect that far exceeds that of traditional fans that rely solely on airflow. They are especially effective in hot, dry, or locally high-temperature environments and are widely used in both outdoor and indoor settings.

[0003] However, its core component, the atomizing plate, needs to be in continuous contact with water to prevent dry burning damage. If the user injects water containing impurities into the small fan, it is very easy to clog the water supply pipe, causing the water supply to the atomizing plate to be interrupted, resulting in dry burning damage. On the other hand, the small fan cannot be used when the user lacks clean water sources outdoors. In the existing technology, although some small fans have a filter structure, the filter screen is fixed and cannot be removed, resulting in low cleaning efficiency for users. Utility Model Content

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] A small cooling fan that can filter impurities, such as Figures 1 to 9 As shown, it includes a handle front shell 1 and a handle rear shell 2 connected by snap fasteners, forming a receiving chamber between them. The handle rear shell 2 has a water mist outlet 201. The top of the handle front shell 1 and the handle rear shell 2 are jointly provided with a water tank body 31 by bolts. The water tank body 31 has a water inlet 301 at the top and a water passage hole 34 at the bottom. The water tank cover 32 with an air inlet 33 on the side wall is located on one side of the water tank body 31. The top outer side of the water tank cover 32 is provided with a water filter device for filtering impurities in the water.

[0028] The water filtration device includes a water inlet frame 331 welded to the top of the water tank cover 32. The top of the water inlet frame 331 is rotatably connected to the cover plate 332 via a hinge. In other embodiments, the water inlet frame 331 and the cover plate 332 can also be connected by a snap-fit. Both the water inlet frame 331 and the cover plate 332 are made of metal. The water inlet frame 331 also has a sliding groove and two support holes. A filter screen plate 333 with two magnets A334 passes through the sliding groove and is placed inside the water inlet frame 331. The filter screen plate 333 is composed of a rectangular frame and a stainless steel filter screen fixedly set inside the frame. The magnets A334 are inserted into the support holes one by one. The magnet B335 is placed inside the water inlet frame 331 and is attracted and cooperates with the cover plate 332. The magnet B335 is used to fix the cover plate 332 to the water inlet frame 331 by magnetic attraction, and the magnet A334 is used to fix the filter screen plate 333 inside the water inlet frame 331 by magnetic attraction.

[0029] The filter screen 333 has two limiting holes, and the water inlet frame 331 has two chambers. The chambers are equipped with clips 336, and springs 337 are connected between the clips 336 and the bottom wall of the chamber. The clips 336 are inserted into the limiting holes one by one, and the clips 336 are used to fix the filter screen 333 in the water inlet frame 331.

[0030] A small cooling fan that can filter impurities also includes a push plate 338, which is welded to a filter screen plate 333. A guide plate 339 is disposed on a water inlet frame 331 and is located above the filter screen plate 333. The guide plate 339 is in contact with the filter screen plate 333, and the push plate 338 is used to assist in pushing the filter screen plate 333.

[0031] A small cooling fan that can filter impurities also includes a motor mounting bracket 41, which is bolted to the water tank body 31. The motor mounting bracket 41 has several air outlets 44. A servo motor 42 is also bolted to the motor mounting bracket 41, and the output shaft of the servo motor 42 has fan blades 43.

[0032] A small cooling fan capable of filtering impurities also includes an atomizing plate bracket 51, which is bolted to the front housing 1 of the handle. The atomizing plate bracket 51 has a water inlet channel and a water outlet channel. The water inlet channel of the atomizing plate bracket 51 is connected to the water passage hole 34 of the water tank body 31. The atomizing plate body 52 is installed on one side of the water outlet channel of the atomizing plate bracket 51, and is coaxially aligned with the water mist outlet 201. The atomizing plate body 52 is used to break the water inside the atomizing plate bracket 51 into tiny mist droplets, and the water mist outlet 201 is used to discharge the water mist prepared by the atomizing plate body 52. A small cooling fan capable of filtering impurities also includes a PCB control board 61, which is bolted to the upper part of the front shell 1 of the handle. The PCB control board 61 is equipped with a charging interface 62 and a button 63, both of which pass through the front shell 1 and the rear shell 2 of the handle. The PCB control board 61 is connected to the servo motor 42 and the atomizing plate body 52 respectively via wires.

[0033] A small cooling fan capable of filtering impurities also includes a lithium battery 7, which is inclinedly disposed in the receiving cavity formed by the front shell 1 and the rear shell 2 of the handle. The lithium battery 7 is connected to the PCB control board 61 through wires and is located below the PCB control board 61.

[0034] When the water tank body 31 is low on water, the user opens the cover 332. The cover 332 no longer presses down on the upper part of the clip 336. The compressed spring 337 pushes the clip 336 upward to reset. The upper part of the clip 336 moves to the outside of the water inlet frame 331, and the lower part of the clip 336 separates from the limiting hole. The user introduces water into the water inlet frame 331. The guide plate 339 is used to assist in guiding the water flow, so that all the water flows into the filter screen part of the filter screen plate 333, avoiding some small impurities from sticking to the non-filter screen area of ​​the filter screen plate 333. This makes it easier for all impurities to be taken away at once when the filter screen plate 333 is pulled out. The filter screen plate 333 is used to filter impurities in the water. The filtered water flows into the water tank body 31 through the water inlet 301.

[0035] After the water tank body 31 is filled with sufficient water, the user can observe whether there are impurities on the filter screen 333. If there are no impurities on the filter screen 333, the user can directly reset the cover 332. Magnet B335 is used to firmly hold the cover 332 in place. The cover 332 pushes the clip 336 downward and locks it into the limiting hole again. The spring 337 is compressed. Through the cooperation of clip 336 and magnet A334, the filter screen 333 is stably fixed in the water inlet frame 331. If there are impurities on the filter screen 333, the user can... The user can choose to clean the impurities at any time. When the user needs to clean the impurities, the user pushes the filter plate 333 out of the water inlet frame 331 using the push plate 338, causing the two magnets A334 to separate from the support hole. Then, the user completely pulls the filter plate 333 out of the water inlet frame 331. After the impurities in the filter plate 333 are cleaned, the user puts the filter plate 333 back into the water inlet frame 331, and the magnets A334 snap into the support hole. After the filter plate 333 is reset, the user finally resets the cover plate 332. By setting up a removable filter plate 333, impurities in the water can be filtered to prevent them from clogging the water supply pipes inside the small fan, ensuring that the atomizing plate body 52 remains moist and preventing dry burning damage, thus ensuring the stable operation of the atomizing plate body 52. ​​On the other hand, when clean water sources are scarce outdoors, users can also obtain water from outside, solving the problem of scarce outdoor clean water sources and meeting the user's need to use the small fan anytime and anywhere.

[0036] When the small fan is needed, the user simply presses button 63, which in turn powers the atomizing plate body 52 and the servo motor 42 via the PCB control board 61. The servo motor 42, once powered, drives the fan blades 43 to rotate at high speed, causing air to be continuously drawn into the water tank body 31 through the air inlet 33 and discharged at high speed from the air outlet 44 in front of the fan blades 43, forming a directional airflow and thus producing a blowing effect. Water in the water tank body 31 flows into the atomizing plate support 51 through the water passage 34, and the atomizing plate body 52 breaks up the water in the atomizing plate support 51. The atomizing plate generates tiny droplets, which are then sprayed out through the water mist outlet 201. The airflow from the fan blades 43 then blows the droplets over a wider area. These droplets absorb heat in the air and evaporate rapidly, thus directly lowering the surrounding air temperature. At the same time, the airflow from the fan blades 43 also accelerates the evaporation of sweat from the skin, achieving a cooling effect. When the small fan needs to be turned off, the user can simply press the button 63 again. When the lithium battery 7 has a low charge, the charging cable can be directly inserted into the charging port 62 to charge the lithium battery 7.

[0037] 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.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
