[0034] The following will further illustrate the technical solution of the present utility model in conjunction with the drawings Figures 1 to 3 and through specific embodiments.

[0035] As Figures 1 - 3 shown, a humidifier with spiral mist output includes a housing 1, a water mist assembly 2, a air supply assembly 3, and a flow guide assembly 4;

[0036] The water mist assembly 2 is arranged inside the housing 1, and the water mist assembly 2 is used to generate water mist;

[0037] The flow guide assembly 4 is arranged at the top of the housing 1. The flow guide assembly 4 is connected to the water mist assembly 2. The flow guide assembly 4 is provided with an annular air duct 45. A plurality of flow guide vanes 46 are circumferentially spaced and vertically inclined in the annular air duct 45. An inclined flow path for guiding the air flow is formed between adjacent flow guide vanes 46;

[0038] The air supply assembly 3 is arranged inside the housing 1. The air outlet end of the air supply assembly 3 communicates with the water mist assembly 2. The air supply assembly 3 is used to send the water mist generated by the water mist assembly 2 into the annular air duct 45.

[0039] This solution enables the water mist to be discharged spirally upward after passing through the guide vanes 46 of the guide component 4. During the discharge process, the water mist undergoes a long spiral process and comes into contact with the inner wall of the annular air duct 45 for a long time. Larger water mist particles will re-aggregate and fall into the annular air duct 45 or condense on the inner wall of the annular air duct 45, and only small particle water mist is discharged into the environment, thus avoiding the problem that traditional humidifiers are prone to water accumulation on the ground or tabletop.

[0040] As Figure 2 shown, the guide component 4 includes a first outer retaining ring 41, a first inner retaining ring 42, a second outer retaining ring 43, and a second inner retaining ring 44;

[0041] The first outer retaining ring 41 and the first inner retaining ring 42 are arranged at the top of the housing 1. The second outer retaining ring 43 and the second inner retaining ring 44 are respectively arranged at the top of the first outer retaining ring 41 and the first inner retaining ring 42. An annular air duct 45 is formed between the first outer retaining ring 41 and the second outer retaining ring 43 and between the first inner retaining ring 42 and the second inner retaining ring 44;

[0042] A plurality of the guide vanes 46 are arranged around between the side walls of the first outer retaining ring 41 and the first inner retaining ring 42.

[0043] As Figure 2 shown, an annular baffle 47 is connected to the top ends of the second outer retaining ring 43 and the second inner retaining ring 44. A plurality of air outlet holes 471 communicating with the annular air duct 45 are formed at the top end of the annular baffle 47.

[0044] Specifically, the provided annular baffle 47 can prevent larger sundries from entering the annular air duct 45, and the air outlet holes 471 can allow the water mist in the annular air duct 45 to be discharged.

[0045] Preferably, the first outer retaining ring 41, the first inner retaining ring 42, and the plurality of guide vanes 46 are of an integrally formed structure, and the second outer retaining ring 43, the second inner retaining ring 44, and the annular baffle 47 are of an integrally formed structure, which is convenient for the assembly of the guide component 4, so that users can select a suitable guide component 4 according to different mist discharge forms. Here, the mist discharge form refers to the spiral angle and the mist discharge height.

[0046] As Figure 3 shown, the water mist component 2 includes a water tank 21 and a first cover plate 24;

[0047] The water tank 21 is arranged in the middle of the housing 1, and an ultrasonic atomizer is provided in the water tank 21;

[0048] The first cover plate 24 is disposed on the top end of the water tank 21. A gas guiding funnel 23 is communicated with the middle part of the bottom end of the first cover plate 24, and an air inlet is formed on the side wall of the gas guiding funnel 23;

[0049] The edge of the first cover plate 24 extends upward to form a mist blocking ring 241. A plurality of air outlets 242 communicated with the annular air duct 45 are formed on the side wall of the mist blocking ring 241. A second cover plate 22 is detachably disposed on the top end of the mist blocking ring 241, and a handle is disposed on the top end of the second cover plate 22.

[0050] Specifically, the ultrasonic atomizer is adopted to generate water mist in the water tank 21. Under the action of the air supply assembly 3, the water mist first enters the gas guiding funnel 23 through the air inlet, then enters the mist blocking ring 241 through the gas guiding funnel 23 and enters the annular air duct 45 through the air outlets 242, and then is guided by the inclined flow channels between a plurality of guide vanes 46 and spirally discharged upward through the air outlet holes 471.

[0051] Furthermore, during the discharging process, the water mist undergoes a long spiral process and contacts the inner wall of the annular air duct 45 for a long time. The water mist with larger particles will re-aggregate and fall into the annular air duct 45 or condense into water droplets on the inner wall of the annular air duct 45. When the accumulated water droplets are excessive, the water droplets will flow into the first cover plate 24 through the air outlet holes 242 and enter the gas guiding funnel 23, and then flow back into the water tank 21 through the gas guiding funnel 23.

[0052] It should be noted that the second cover plate 22 can be detachably installed on the mist blocking ring 241 through a buckle structure. The user only needs to hold the handle to take out the second cover plate 22 together with the first cover plate 24 from the guiding assembly 4, which is convenient and fast. Moreover, the second cover plate 22 is connected to the mist blocking ring 241 through the buckle structure, which is convenient for the disassembly and assembly of the second cover plate 22 and the first cover plate 24, so as to clean the surface of the first cover plate 24.

[0053] As Figures 2 - 3 shown, the diameter of the mist blocking ring 241 is smaller than the diameters of the first inner retaining ring 42 and the second inner retaining ring 44, and the diameter of the second cover plate 22 is smaller than the diameters of the first inner retaining ring 42 and the second inner retaining ring 44.

[0054] Specifically, this structure can facilitate the removal of the second cover plate 22 and the mist blocking ring 241 from the first inner retaining ring 42 and the second inner retaining ring 44 of the guiding assembly 4, so that there is no obstruction directly above the water tank 21, thus facilitating the user to add water to the water tank 21.

[0055] As Figure 2As shown, the air supply component 3 includes a fan 31 and an installation bin 32. The fan 31 is respectively connected between the outer bottom wall of the water tank 21 and the inner bottom wall of the housing 1. The inner bottom wall of the water tank 21 protrudes upward to form the installation bin 32. The air outlet end of the fan 31 communicates with the installation bin 32. The top end of the side wall of the installation bin 32 is provided with an air outlet 321, and the side wall of the housing 1 is provided with an air inlet.

[0056] Specifically, the fan 31 sends the air entering from the air inlet into the installation bin 32, and discharges it into the water tank 21 through the air outlet 321 to be mixed with the water mist, so as to send the water mist into the air guide funnel 23 through the air inlet.

[0057] As Figure 2 shown, the height of the second outer retaining ring 43 and the second inner retaining ring 44 is at least 50 mm, and the height of the guide vane 46 is 0.2 - 0.5 times the height of the second outer retaining ring 43.

[0058] Specifically, the height of the second outer retaining ring 43 and the second inner retaining ring 44 being at least 50 mm can enable the water mist to undergo a sufficient spiral process to ensure that only small particle water mist is discharged into the environment.

[0059] It should be noted that the height of the guide vane 46 is 0.2 - 0.5 times the height of the second outer retaining ring 43. Since the fogging form is spiral, if the guide vane 46 is too short, the fog will be blown out before being guided into a spiral shape. If the guide vane 46 is too high, more power will be lost through the relatively high guide vane 46, resulting in the fog coming out of the guide vane 46 not being able to form a spiral shape.

[0060] As Figure 2 shown, the number of the guide vanes 46 is at least five.

[0061] Specifically, the number of the guide vanes 46 is at least five. If the number of the guide vanes 46 is too small, the fog will not form a spiral shape after passing through the guide vanes 46. If the number of the guide vanes 46 is too large, the spiral fog formed after the fog passes through the guide vanes 46 will interfere with each other, resulting in an irregular fog formation.

[0062] As Figure 2 shown, the diameter of the first inner retaining ring 42 is 0.5 - 0.9 times the diameter of the first outer retaining ring 41.

[0063] Specifically, the diameter of the first inner retaining ring 42 being 0.5 - 0.9 times the diameter of the first outer retaining ring 41 can limit the area of the annular air duct 45 occupied by the guide vanes 46. If the area of the annular air duct 45 occupied by the guide vanes 46 is too large, a large amount of water mist generation and a large air volume are required at the lower part of the guide vanes 46 to drive the water mist to form a spiral through the guide vanes 46.

[0064] As shown Figure 2 in the figure, it further includes an annular lamp shade 5, the annular lamp shade 5 is arranged between the top ends of the side walls of the housing 1 and the water tank 21, the annular lamp shade 5 is located directly below the annular air duct 45, the side wall of the annular lamp shade 5 is closely attached to the side walls of the housing 1 and the water tank 21, and an annular light guide ring 51 is arranged inside the annular lamp shade 5;

[0065] Both the second outer retaining ring 43 and the annular lamp shade 5 are made of transparent materials.

[0066] Specifically, both the second outer retaining ring 43 and the annular lamp shade 5 are made of transparent materials, so that the light emitted by the annular light guide ring 51 can irradiate into the annular air duct 45, and the spiral upward rotation effect of the water mist can be seen through the transparent second outer retaining ring 43 under the irradiation of the light, making the appearance of the humidifier more cool and attractive when it works.

[0067] Furthermore, the water droplets in the annular air duct 45 will converge to the top end of the annular lamp shade 5, then flow into the interior of the first cover plate 24 through the air outlet 242, and then flow back to the water tank 21 through the air guide funnel 23.

[0068] The technical principle of the present utility model has been described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed in any way as a limitation on the protection scope of the present utility model. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present utility model without creative efforts, and these embodiments will fall within the protection scope of the present utility model.
