[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example

[0033] like Figure 1-6 As shown, an embodiment of the present invention provides a bladeless fan, including a main body shell 1 and an upper shell 2. At least one fan 11 is provided inside the main body shell 1, and an air outlet 21 is provided on one side of the upper shell 2.

[0034] The upper housing 2 has a through hole 22 extending through its front and rear surfaces. A water tank 23 is installed inside the through hole 22, and an atomizing device 24 is installed on the water tank 23.

[0035] The bottom of the main shell 1 is provided with a base 12, and the inside of the main shell 1 is provided with a swaying mechanism 13, which is used to drive the main shell 1 and the upper shell 2 to rotate relative to the base 12.

[0036] By setting an atomizing device 24 on the water tank 23, the synergistic function of blowing air and humidifying is realized, providing a cool and moist air delivery experience. Its fan 11 is hidden inside the main body shell 1, and the fan blades are completely invisible, effectively eliminating the risk of pinching hands that is common with traditional fans 11, making operation safer. The dual fans 11 combined with several air inlets 14 on the main body shell 1 are used for efficient airflow, resulting in smooth operation and less noise, achieving silent blowing. The main control board 17 can precisely control the fan 11 to achieve multiple wind speed adjustments. In addition, the light from the light panel 251 is refracted and reflected through the transparent water tank 23 to form a uniform and soft ambient light, enhancing the product's aesthetics and the mood for nighttime use. The air delivery angle can be adjusted through the oscillating mechanism 13, making it more convenient to use.

[0037] like Figure 1-6 As shown, in some embodiments, the top of the through hole 22 is provided with a locking hole 221, the top of the water tank 23 passes through the locking hole 221 and extends to the top of the upper shell, the top of the water tank 23 is provided with a water filling plug 231, the interior of the locking hole 221 and one side of the top of the water tank 23 are provided with an installation groove 25, the interior of the installation groove 25 is provided with a light plate 251, and the bottom of one side of the water tank 23 is provided with a drain plug 232.

[0038] The water tank 23 is made of transparent material (GPPS, PC or acrylic). A locking hole 221 is opened on the top of the through hole 22 of the upper shell 2 to provide a positioning point for the water tank 23. After the top of the water tank 23 passes through the locking hole 221, the water inlet plug 231 is used to seal the water inlet on the top of the water tank 23, and the drain plug 232 is used to drain the water stored at the bottom of the water tank 23. The mounting groove 25 on one side of the top of the water tank 23 allows the light to be more accurately directed to the water tank 23 after the lamp beads at the bottom of the lamp board 251 are lit.

[0039] The water tank 23 is suspended and centrally fixed, making the water tank 23 itself the visual focus within the through hole 22. The light from the light panel 251 can directly illuminate the water tank 23. Through the refraction and reflection of the water and the water tank 23, a uniform and soft ambient light effect is created, enhancing the product's aesthetics and nighttime user experience. The drain plug 232 facilitates regular cleaning and maintenance of the water tank 23. Adjusting the lighting effect (light color) can further enhance the ambiance.

[0040] like Figure 1-6 As shown, in some embodiments, the atomizing device 24 includes an atomizing plate 241, a water-absorbing filter element 242, and an atomizing plate bracket 243; an atomizing groove 233 for installing the atomizing plate 241 is provided on one side of the water tank 23, and the atomizing plate bracket 243 is installed on one side of the atomizing groove 233 by screws.

[0041] The atomizing plate 241 is integrated into the atomizing groove 233 specially opened on the side wall of the water tank 23, and is pressed and fixed by an independent atomizing plate bracket 243 and screws to form a sealed installation structure to prevent water leakage from the water tank 23. The fixing method of atomizing plate bracket 243 and screws ensures a firm and reliable connection, ensuring the sealing between the atomizing plate 241 and the water tank 23, while facilitating production assembly and later maintenance and replacement.

[0042] The bottom of the atomizing groove 233 extends downward to form a channel for storing the wire of the atomizing plate 241. The atomizing plate bracket 243 also extends downward to form a cover to cover the channel, improving the overall appearance of the product.

[0043] like Figure 1-6 As shown, in some embodiments, a filter element support 234 is provided inside the water tank 23, and the water-absorbing filter element 242 is disposed inside the filter element support 234. One top end of the water-absorbing filter element 242 extends into the interior of the atomizing groove 233 and contacts the atomizing plate 241.

[0044] Under capillary action, the water-absorbing filter element 242 continuously draws water from the bottom of the water tank 23 to its top and directly supplies it to the atomizing plate 241, which is in close contact with it. The filter element support 234 ensures the stability and directionality of the position of the water-absorbing filter element 242, ensuring that its top can accurately and continuously contact the atomizing plate 241, thereby achieving a stable and efficient atomization volume. This structure utilizes the capillary principle for water supply, eliminating the need for an additional water pump, simplifying the structure, and reducing costs and noise.

[0045] like Figure 1-6 As shown, in some embodiments, there are two fans 11. The upper housing 2 has two symmetrically arranged air ducts 26 inside. The air outlet 21 is located on one side of the air duct 26. The bottom of the two air ducts 26 corresponds to the air outlets 111 of the two fans 11 respectively. The main housing 1 is cylindrical. A number of air inlets 14 are arranged around the main housing 1.

[0046] The air outlet 21 is inverted U-shaped, and the two air ducts 26 are combined to form an inverted U-shape. The design of the two fans 11 in parallel is adopted, which together blow air into the inverted U-shaped air duct 26. The airflow is drawn in from the air inlet 14 around the main shell 1, accelerated by the two fans 11, and enters the inverted U-shaped air duct 26 from both ends of the bottom. Finally, it is blown out from the slit-type air outlet 21 on one side of the air duct 26.

[0047] The dual-fan design 11 provides greater air volume and air pressure, overcomes the airflow resistance of the inverted U-shaped air duct 26, and ensures strong and uniform airflow. The cylindrical main body shell 1 and the surrounding air inlet 14 achieve 360-degree all-round air intake, improve air intake efficiency, and have a more harmonious and unified appearance design.

[0048] like Figure 1-6 As shown, in some embodiments, the bottom of the main body shell 1 is provided with a bottom shell 15, the swaying mechanism 13 includes a swaying motor 131 disposed inside the bottom shell 15, and a limiting bracket 132 disposed at the bottom of the bottom shell 15. The output end of the swaying motor 131 extends into the interior of the base 12, and the top of the base 12 is also provided with a travel limiting hole 121 that is sleeved with the limiting bracket 132.

[0049] The main shell 1 and the bottom shell 15 are fixed by snap-fit. The output end of the oscillating motor 131 is flat and extends downward to connect with the base 12. At the same time, at least one limiting bracket 132 is fixed at the bottom of the bottom shell 15. The limiting bracket 132 extends downward into the travel limiting hole 121 opened at the top of the base 12 to limit the oscillating stroke of the oscillating motor 131.

[0050] The oscillating mechanism 13 adopts intelligent reverse control based on mechanical limit and current detection. When the fan 11 rotates to one end of the set angle, the limit bracket 132 will contact the end of the travel limit hole 121. Since the base 12 is restricted by the bottom shell 15 and cannot continue to rotate, the output shaft of the oscillating motor 131 is mechanically locked. At the moment the oscillating motor 131 is locked, its working current will rise sharply. The main control board 17 monitors the working current of the oscillating motor 131 in real time. When the current value exceeds the preset threshold, it is determined that the limit point has been reached. Subsequently, the main control board 17 immediately controls the oscillating motor 131 to stop rotating in the original direction and rotate in the opposite direction. When the oscillating motor 131 rotates to the limit point at the other end, it will reverse again through the above-mentioned current detection mechanism, thereby realizing the automatic and continuous reciprocating oscillation of the fan 11 within the set angle.

[0051] like Figure 1-6 As shown, in some embodiments, the bottom of the base 12 is provided with a bottom cover 122, the inside of the base 12 is provided with a power control board 16, the power control board 16 is integrated with a power interface 161, and one side of the bottom shell 15 is provided with a clearance notch 151 corresponding to the position of the power interface 161.

[0052] The clearance notch 151 is used to avoid the power interface 161, so that the use of the oscillation function will not be affected when the power interface 161 is connected to the power cord. In the future, a rechargeable battery can be added inside the main body shell 1 and charged through the power interface 161, making it more convenient to use without having to be connected to the power cord all the time.

[0053] like Figure 1-6 As shown, in some embodiments, a main control board 17 is mounted on the top of the bottom shell 15 via a main control board clamping block 152. The main control board 17 integrates a display screen 171 and several function buttons 172, a fan 11 switch and gear adjustment button, an atomizing device 24 switch and gear adjustment button, an oscillating mechanism 13 switch button, and a light panel 251 switch and mode adjustment button. The light panel 251, atomizing plate 241, fan 11, oscillating motor 131, and power control board 16 are all electrically connected to the main control board 17.

[0054] The main control board clamping block 152 ensures the assembly stability of the main control board 17. Placing the main control board 17 on the top of the bottom shell 15 makes it easy to align the integrated display screen 171 and function buttons 172 with the corresponding openings on the main shell 1, thus achieving good human-computer interaction.

[0055] like Figure 1-6 As shown, in some embodiments, the main body shell 1 is also provided with a waterproof button 18 corresponding to the function button 172 and a light shield 19 corresponding to the display screen 171.

[0056] The waterproof button 18 effectively prevents liquids and dust from entering the interior of the main body shell 1 through the button gaps, improving the product's sealing protection level and durability. The light shield 19 is usually made of dark transparent material, which allows light to pass through to clearly display the information on the screen 171, while reducing the reflection and interference of external ambient light on the screen 171, thus improving the visibility.

[0057] like Figure 1-6 As shown, in some embodiments, the upper housing 2 includes a front housing 27 and a rear housing 28. The front housing 27 is provided with a plurality of buckles 271 on the side facing the rear housing 28. The rear housing 28 is provided with a locking block 281 on the side facing the front housing 27, which is engaged with the plurality of buckles 271 one by one. A handle 29 is movably provided on the top of the rear housing 28.

[0058] The two ends of the handle 29 are movably connected to the top of the rear shell 28 via a pivot. The front shell 27 and the rear shell 28 are connected by a buckle 271, realizing screwless assembly, simplifying the production process, reducing costs, and the handle 29 greatly facilitates users to move and transport the product, improving the convenience of use. Especially for home appliances with a certain size and weight, the design is more user-friendly.

[0059] In summary, by setting the atomizing device 24 on the water tank 23, the synergistic function of blowing air and humidifying is achieved, providing a cool and moist air delivery experience. The fan 11 is hidden inside the main body shell 1, and the fan blades are completely invisible, effectively eliminating the risk of pinching hands that is common with traditional fans 11, making operation safer. The use of dual fans 11 combined with several air inlets 14 on the main body shell 1 for efficient airflow is achieved, resulting in stable operation, lower noise, and silent blowing. The main control board 17 can precisely control the fan 11 to achieve multiple wind speed adjustments. In addition, the light from the light panel 251 is refracted and reflected by the transparent water tank 23 to form a uniform and soft ambient light, enhancing the product's aesthetics. The air delivery angle can be adjusted through the oscillating mechanism 13, making it more convenient to use.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
