The mist dividing member 5 is used to convey water mist to the spray pipe 2.

[0026] In this embodiment, the spray assembly 4 includes a water storage cavity 41, an atomization cavity 42, a mist outlet channel 43 and a fan 44. The mist outlet channel 43 is located in the middle of the water storage cavity 41; the atomization cavity 42 is arranged at the bottom of the mist outlet channel 43; an atomizer 420 is arranged in the atomization cavity 42, and the fan 44 is arranged in the atomization cavity 42 and is oppositely arranged with the atomizer 420 for driving the water mist generated by the atomizer 420 to flow towards the mist outlet channel 43; one end of the mist outlet channel 43 is communicated with the atomization cavity 42, and the other end is communicated with the mist dividing member. The mist outlet channel 43 is used for conveying the water mist generated by the atomizer 420 to the mist dividing member 5.

[0027] In this embodiment, the mist dividing member 5 is provided with a mist dividing structure 51 which is used for dividing the water mist blown towards the mist dividing structure 51 into multiple strands and then spraying it out through the spray pipe 2.

[0028] In this embodiment, the mist dividing structure 51 bulges outwards to form an arc-shaped mist guiding space, and a conical grille 52 is arranged at the tail of the arc-shaped mist guiding space, and a conical sealing ring is arranged at the conical grille 52.

[0029] In this embodiment, the cold mist tower fan further includes a reflux structure 6 which is located below the spray pipe 2. The reflux structure 6 includes a guide vane 61 and a guide rib 63. The guide vane 61 is inclined with respect to the spray pipe 2, and the top of the guide vane 61 protrudes from the spray pipe 2. A reflux hole 62 is opened at the joint of the guide vane 61 and the spray pipe 2. The guide rib 63 is arranged on the mist dividing structure 51 and is communicated with the guide vane 61.

[0030] In this embodiment, the cold mist tower fan further includes an inclined surface guide wall 64 which is arranged on the outer side wall of the mist outlet channel 43 and is located below the guide rib 63.

[0031] In this embodiment, the housing 1 includes a front housing 13 and a rear housing 14. The front housing 13 is buckled on the rear housing 14 and is adapted to each other. After the front housing 13 and the rear housing 14 are connected, a sealed cavity is formed. The guide rib 63 is located in the sealed cavity, and a gap is reserved between the guide rib 63 and the front housing 13.

[0032] In this embodiment, the water storage cavity 41 is in an open shape, and a water filling baffle 7 is further arranged at the top of the water storage cavity 41, and the water filling baffle 7 is movably connected to the rear housing 14..

[0033] In this embodiment, the spray pipe 2 is uniformly provided with a plurality of mist outlet holes 21, and the mist outlet holes 21 are in the shape of slender strips.

[0034] Specifically, in this application, the atomizer 420 in the atomization chamber 42 generates water mist, combined with the unique design of the spray pipe 2 and the mist dividing member 5. The wind generated by the tower fan wind drum 3 evenly diffuses the water mist into the air through the spray pipe 2, not only achieving the effects of cooling and humidifying. At the same time, the humidifying filter is omitted, solving the influence of the humidifying filter on the air intake of the tower fan, and also optimizing the air duct structure of the tower fan, further improving the wind speed and air volume. Thus, a cool effect is provided in hot weather.

[0035] Further, the wind drum 3 is used to generate air flow. The air outlet 12 is located in the middle of the air duct. Two spray pipes 2 are provided on both sides of the air duct and are parallel to the wind drum 3. A number of slender strip-shaped mist outlet holes 21 are provided on the spray pipe 2. The spray pipe 2 serves to guide the water mist. The purpose of arranging the spray pipe 2 on both sides of the air duct is not to block the air outlet of the tower fan. The mist outlet holes 21 are composed of multiple slender strip-shaped small holes. On the one hand, it can make the mist output uniform. On the other hand, the slender strip-shaped design can break the surface tension of the water droplets, so that the mist outlet holes 21 are not easily blocked by the condensed water droplets, affecting the mist output effect and resulting in poor cooling effect.

[0036] Under the action of the small fan 44 in the atomization chamber 42, the water mist generated by the atomizer 420 is transported from the mist outlet channel 43 to the mist dividing structure 51, and then the mist dividing structure 51 divides it into two parts. The water mist passing through the mist dividing structure 51 respectively enters the two spray pipes 2 connected to the mist dividing structure 51, and then sprays out from the mist outlet holes 21. The mist dividing structure 51 bulges outwards to form an arc-shaped mist guiding space. The area of the arc-shaped mist guiding space is relatively large. The purpose of this design is to make the mist output of the two spray pipes 2 balanced, so that the mist output of one spray pipe is not large and the mist output of the other is not small. At the same time, the water mist is divided into multiple strands to enhance the atomization effect.

[0037] Among them, since the water mist generated by the oscillator is easy to condense into water droplets at the mist outlet holes 21, it is easy to wet the surface of the tower fan and cause water accumulation on the ground. Therefore, a diversion piece 61 and a return hole 62 are provided to collect the condensed water droplets and guide them back to the water tank. The diversion piece 61 and the spray pipe 2 are designed in an inclined manner for the purpose of guiding the condensed water droplets. The outermost end of the diversion piece 61 protrudes from the front of the spray pipe 2, so that the diversion piece 61 can smoothly receive the water droplets flowing down from the surface of the spray pipe 2. By providing a diversion rib 63 below the diversion piece 61, and the diversion rib 63 is located on the mist dividing structure 51, and a diversion wall 64 is provided below the diversion rib 63. The condensed water droplets can enter the interior of the tower fan body along the diversion piece 61, and then flow into the water storage cavity 41 along the diversion rib 63 and the diversion wall 64. It not only guides the water droplets back to the water storage cavity 41, but also prevents the water droplets from directly dripping into the water storage cavity 41, forming a dripping sound. The diversion wall 64 reduces the drop height of the water droplets, thereby reducing the noise of the water droplets falling into the water tank cavity, so as to achieve a silent effect.

[0038] The fog separation structure 51 is designed with an outwardly bulging arc-shaped fog guiding space and a conical grille 52. The arc-shaped fog guiding space prevents water from staying inside, playing a role in preventing water accumulation. The conical grille 52 is for convenient installation and alignment. At the same time, the grille design allows the water mist to pass through smoothly. The conical sealing ring is a flexible conical sealing ring, which is convenient for installation and can still achieve a sealing effect in the case of assembly errors.

[0039] The purpose of the gap left between the flow guiding rib 63 and the front shell 13 is to prevent the front shell 13 from adhering to water droplets. The spray assembly 4 and the housing 1 are designed to be detachable, aiming to be pulled out integrally during actual use for convenient cleaning and maintenance. Specifically, the spray assembly 4 is also provided with components such as a water level control 45 and a dry-burning induction 46. A water adding flap 7 is movably connected to the rear shell 14, and the design of the water adding flap 7 covering the top of the water storage cavity 41 enables the water adding function to be realized without removing the spray assembly 4. The water storage cavity 41 has an open design. The side of the water adding flap 7 extends downward to form an arc-shaped clamping plate 71, and the clamping plate is recessed inward with a clamping groove 72. Through the convex structure 15 provided on the rear shell 14 of the tower fan and matching with the clamping groove, the angle when the water adding flap 7 is flipped outward is controlled. At the same time, when the water adding flap 7 is opened, the clamping plate 71 plays a limiting role, making the water adding operation more convenient.

[0040] This application cleverly integrates the atomization, wind diffusion, and water mist recycling mechanisms to provide a continuous cold mist effect. At the same time, through the reflux structure 6, mainly to prevent water from flowing outside, resulting in the surface of the tower fan being wet and water accumulating on the ground, etc., improving the overall efficiency. This cold mist tower fan not only improves the cooling efficiency but also optimizes the user experience.

[0041] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
