[0036] Furthermore, the terms "first", "second", etc. are used only for descriptive purposes and do not connote or imply relative importance or an ordering between or among the indicated technical features. Thus, features defined with "first", "second" can include one or more of the features explicitly or implicitly. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise expressly specified.

[0037] The humidifier air duct structure 1 provided by the embodiment of the present application will be described. The humidifier air duct structure 1 has a first air duct 101 and a second air duct 102 for air supply, and also has a third air duct 103 for mist supply. When air is supplied and mist is generated at the same time, the air flows in the first air duct 101 and the second air duct 102 converge at the third air duct 103, which can make the mixing of the mist and the air more uniform, and the temperature of the mist out is stable. Moreover, by adjusting the air force of the first air duct 101 and the second air duct 102, the temperature of the mist out can also be adjusted.

[0038] Please refer to Figures 1 to 3 The humidifier air duct structure 1 includes a shell assembly 11 and a mist pipe 12.

[0039] The mist pipe 12 is arranged inside the shell assembly 11, and the mist after being atomized by the atomization structure 43 enters the inlet of the mist pipe 12, and then is discharged from the outlet of the mist pipe 12. The mist pipe 12 has the third air duct 103, that is, the generated mist is discharged to the outside of the humidifier through the third air duct 103. In combination Figure 2 The direction of the arrow at the mist pipe 12 is the flow direction of the mist in the third air duct 103.

[0040] The inside of the shell assembly 11 has the first air duct 101 and the second air duct 102, and both the first air duct 101 and the second air duct 102 are used for air supply. The air inlet direction of the first air duct 101 and the air inlet direction of the second air duct 102 are different, so that the first air duct 101 and the second air duct 102 can respectively transport air to two different directions to form two air flows with different directions. Moreover, the air outlet of the first air duct 101 and the air outlet of the second air duct 102 are both communicated to the third air duct 103, that is, the two air flows output from the first air duct 101 and the second air duct 102 respectively both enter the third air duct 103, fully mix with the mist in the third air duct 103, and assist the mist to be quickly discharged under the driving of the air flow. In combination Figure 2 and Figure 3 The directions of the arrows on the left and right sides of the mist pipe 12 are respectively the flow directions of the air flows in the first air duct 101 and the second air duct 102.

[0041] Because the air flows in the first air duct 101 and the second air duct 102 respectively when the humidifier works, the shell assembly 11 is cooled, the temperature rise of the shell assembly 11 is prevented, the air flow in the shell assembly 11 is accelerated, and the condensed water in the shell assembly 11 is prevented. Moreover, the air and the mist are mixed more uniformly, and the mist temperature is more stable. In addition, the air flow of the first air duct 101 and the second air duct 102 is adjusted to adjust the mist temperature. For example, when the mist is steam, the greater the air flow, the lower the mist temperature, and the smaller the air flow, the higher the mist temperature.

[0042] The humidifier air duct structure 1 in the above embodiment comprises the shell assembly 11 and the mist pipe 12, the first air duct 101 and the second air duct 102 for air supply are formed between the shell assembly 11 and the mist pipe 12, the third air duct 103 for mist supply is arranged in the mist pipe 12, the air flow generated in the shell assembly 11 is separated into two air flows through the first air duct 101 and the second air duct 102 respectively, the two air flows flow to the third air duct 103 through the first air duct 101 and the second air duct 102 respectively to mix with the atomized gas, so that the atomized gas and the air are mixed more uniformly, the mist temperature of the mist outlet is more uniform, and the mist temperature is not high or low, and the mist temperature can be quickly adjusted by adjusting the air flow.

[0043] In one embodiment of the present application, please refer to Figure 2 and Figure 3 , the air inlet directions of the first air duct 101 and the second air duct 102 are symmetrically arranged about the central axis. The air inlet direction of the first air duct 101 refers to the direction of the air flow entering the first air duct 101, and the air inlet direction of the second air duct 102 refers to the direction of the air flow entering the second air duct 102. The air inlet directions of the first air duct 101 and the second air duct 102 can be opposite, or can be obtuse or acute. When the air inlet directions of the first air duct 101 and the second air duct 102 are different, the two air inlet directions must be symmetric about a plane, and the plane is the central axis. Please refer to Figure 2 , the central axis can be a vertically arranged plane.

[0044] The air inlet directions of the first air duct 101 and the second air duct 102 can be opposite, so that the paths of the first air duct 101 and the second air duct 102 are more different, and the possibility of the air flow mixing with each other in the first air duct 101 and the second air duct 102 is reduced.

[0045] Optionally, the first air duct 101 and the second air duct 102 are also symmetrically arranged about the middle axis, so that the first air duct 101 and the second air duct 102 have the same structure, and the air flow rate and size of the air flow flowing out of the first air duct 101 and the second air duct 102 to the third air duct 103 are also the same, which helps the air flow and the mist to be mixed more uniformly.

[0046] In one of the embodiments of the present application, referring to Figure 2 and Figure 3 , the shell assembly 11 includes a shell structure 111 and a partition plate 112 arranged inside the shell structure 111. The partition plate 112 divides the inside of the shell structure 111 into a first space 115 and a second space 116, the first space 115 is arranged below the partition plate 112, and the second space 116 is arranged above the partition plate 112. The partition plate 112 can be arranged horizontally or at an angle, as long as it can separate the inside of the shell structure 111 into two spaces.

[0047] The air inlet of the first air duct 101 and the air inlet of the second air duct 102 are both arranged in the first space 115. The partition plate 112 is provided with a first air guide opening 1121 and a second air guide opening 1122. The first air duct 101 passes through the first air guide opening 1121, and the second air duct 102 passes through the second air guide opening 1122. That is, the air flow in the first air duct 101 will pass through the first air guide opening 1121, and the air flow in the second air duct 102 will pass through the second air guide opening 1122.

[0048] Optionally, the shell assembly 11 further includes an air guide structure 117 arranged in the first space 115, and the air guide structure 117 is used for guiding the air flow. Specifically, the air guide structure 117 and the shell assembly 11 form the above-mentioned first space 115, and the front sections of the first air duct 101 and the second air duct 102 are both located in the first space 115. The air guide structure 117 is used for making part of the air flow flow along the first air duct 101 and flow towards the first air guide opening 1121 to the second space 116, and making another part of the air flow flow along the second air duct 102 and flow towards the second air guide opening 1122 to the second space 116.

[0049] Optionally, the air guide structure 117 is arranged close to one side of the shell structure 111, so that the air flow of the first air duct 101 flows towards one side of the air guide structure 117, and the air flow of the second air duct 102 flows towards the other side of the air guide structure 117. The air guide structure 117 can be a columnar structure, or other shapes.

[0050] Optionally, the first air guide ports 1121 and the second air guide ports 1122 are both in plurality, and the specific shapes of the first air guide ports 1121 and the second air guide ports 1122 are not limited here. The first air guide ports 1121 and the second air guide ports 1122 can be arranged on the opposite sides of the baffle 112 relative to the mist pipe 12.

[0051] The mist pipe 12 is arranged in the second space 116. After the air flow of the first air duct 101 and the air flow of the second air duct 102 flow into the second space 116, both of them flow towards the mist pipe 12, so that the air flow of the first air duct 101 and the air flow of the second air duct 102 converge at the mist pipe 12. The baffle 112 is also provided with a mist outlet. The mist pipe 12 is arranged opposite to the mist outlet, so that the generated mist can enter the inside of the mist pipe 12 through the mist outlet.

[0052] In one of the embodiments of the present application, please refer to Figure 3 The baffle 112 is protruded at the circumference of the mist pipe 12 to form an annular rib 1123.

The baffle 112 is provided with a ventilation hole (not shown in the figure) in the area surrounded by the annular rib 1123, for the mist to enter the mist pipe 12 through the ventilation hole. In this way, if the user misoperates to add water into the humidifier from the mist pipe 12, the annular rib 1123 can have a certain guiding and stopping splashing effect, so that the water flow passes through the mist pipe 12, enters the atomizing chamber 411 through the mist outlet of the baffle 112, and avoids spilling to other areas of the humidifier, thereby ensuring the safety of the humidifier.

[0053] In one of the embodiments of the present application, please refer to Figure 2 and Figure 3 The baffle 112 has an accommodating space 1124 inside, the accommodating space 1124 has a hollow hole, and the inside of the accommodating space 1124 is used to place an odor emitting body 1125. The arrangement of the hollow hole enables the odor emitting body 1125 to emit the odor such as fragrance more quickly. The odor emitting body 1125 can be essential oil, aromatherapy block, etc., and the odor that can be emitted by the odor emitting body 1125 is not limited here. The accommodating space 1124 at least partially faces the air inlet of the mist pipe 12, so that the odor emitted by the odor emitting body 1125 is more easily entered into the inside of the mist pipe 12, thereby achieving the purpose of aromatherapy. In other embodiments, the shell structure 111 is provided with an accommodating space for accommodating the odor emitting body 1125. The odor emitting body 1125 emits the odor to the inside space of the shell structure 111, and then enters the mist pipe 12, thereby also achieving the purpose of aromatherapy.

[0054] Optionally, the shell structure 111 is provided with an aroma replacement opening, and an aroma replacement door 1112 is arranged at the aroma replacement opening. One side of the accommodation space 1124 is open, and the open end is opposite to the aroma replacement opening, so that the aroma replacement door 1112 is opened to replace the aroma or the like aroma emitting body 1125 in the accommodation space 1124.

[0055] In one embodiment of the present application, the fog pipe 12 is arranged in a spaced manner with the partition plate 112 at one end close to the partition plate 112, so that there is a gap between the fog pipe 12 and the partition plate 112, and the airflow of the first air duct 101 and the second air duct 102 can enter the inside of the fog pipe 12 through the gap between the fog pipe 12 and the partition plate 112.

Optionally, the containing space 1124 is arranged on the partition plate 112.

[0079] In one embodiment of the present application, please refer to Figure 5 The water tank 3 comprises a tank body 31 having a water outlet, a float structure 32 arranged at the bottom of the tank body 31, and a valve structure fixed at the water outlet of the tank body 31, and the float structure 32 can be arranged on the base body 41. The tank body 31 is detachably connected to the base body 41, and when the tank body 31 is removed from the base body 41, the float structure 32 is separated from the valve structure, the valve structure is automatically closed, and the tank body 31 is in a closed state, so that the tank body 31 can be conveniently removed and water is added; after the tank body 31 is filled with water, it is placed on the base body 41, and the float structure 32 opens the valve structure, and the water in the tank body 31 enters the base body 41.

[0080] Optionally, the base body 41 has a water storage groove 412, and the float structure 32 is arranged in the water storage groove 412. The mist atomization cavity 411 is arranged on one side of the water storage groove 412, and the opening 414 of the mist atomization cavity 411 and the water storage groove 412 are arranged on opposite sides of the base body 41.

[0081] In one embodiment of the present application, please refer to Figure 8The outlet of the water tank 3 and the inlet of the atomizing cavity 411 are provided with a transition flow channel 415. Since the water storage groove 412 is arranged on the base body 41, the transition flow channel 415 can be arranged on the base body 41 and between the water storage groove 412 and the atomizing cavity 411, so that the water in the water storage groove 412 flows into the atomizing cavity 411 through the transition flow channel 415. Alternatively, the transition flow channel 415 is arranged on the top of the base body 41. Since the liquid level in the water storage groove 412 is always the same, when the liquid level in the water storage groove 412 is higher than that in the atomizing cavity 411, the water in the water storage groove 412 flows into the atomizing cavity 411 through the transition flow channel 415.

[0082] Alternatively, referring to Figure 9 The transition flow channel 415 is internally provided with a heat insulation piece 45, which is used to prevent the heat of the atomizing cavity 411 from being transmitted to the inside of the water tank 3. The heat insulation piece 45 has a plurality of stop grids 452 arranged in sequence along the water flow direction, and the stop grids 452 have gaps with the side wall or bottom wall of the transition flow channel 415, so that the water flow can only flow slowly. When the water in the atomizing cavity 411 boils, the water level change will not be transmitted to the water storage groove 412 and the water tank 3 instantaneously, so that the heat insulation piece 45 has the effect of preventing the water in the atomizing cavity 411 from flowing back into the water tank 3.

[0083] Alternatively, the heat insulation piece 45 comprises a main structure 451, and a plurality of stop grids 452 are arranged on the inner wall of the main structure 451 facing the transition flow channel 415 and arranged in sequence along the water flow direction. The side of the main structure 451 away from the transition flow channel 415 is also provided with a handle 453, which facilitates the removal of the stop grids 452 and the cleaning of the stop grids 452 and the transition flow channel 415. The stop grids 452 comprise first stop grids 4521 and second stop grids 4522, and the length and width of the first stop grids 4521 and the second stop grids 4522 are different, and the first stop grids 4521 and the second stop grids 4522 are arranged alternately, so that the water flow between adjacent stop grids 452 is slower, further improving the heat insulation effect.

[0084] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
