Referring to fig. 3, as for the air duct 200, as the upper air duct 200 is disposed in the housing 10, the air duct 200 has an air outlet 201 communicated with the water mist channel 100 and an air inlet 202 for air intake, the air outlet 201 is located on an extending path of the water mist channel 100, the air outlet 201 is located between the mist inlet 101 and the mist outlet 102, the fan assembly 300 is configured to flow air from the air inlet 202 to the air outlet 201, so that air is generated in the air duct 200, and the heating assembly 400 can heat air flowing into the water mist channel 100 in the air duct 200, so that the air flowing into the water mist channel 100 in the air duct 200 is hot air.

The water mist channel 100 comprises a first section 110, the first section 110 is a part of the water mist channel 100 from the air outlet 201 to the mist outlet 102, and the air duct 200 is configured such that the air flow in the air duct 200 enters the first section 110 after being output from the air outlet 201 and flows toward the mist outlet 102, but does not flow toward the mist inlet 101. Through the cooperation of this first section 110 and wind channel 200, can bring three concrete effects at least, specifically following first effect, second effect and third effect.

The first effect is as follows: the air duct 200 inputs the air flowing from the air outlet 201 toward the mist outlet 102 into the first section 110, that is, the air in the air duct 200 continues to flow from the air outlet 201 toward the mist outlet 102 after entering the first section 110, and further drives the water mist in the first section 110 to rapidly flow from the air outlet 201 toward the mist outlet 102, and finally to be sprayed out through the mist outlet 102, so that the pressure in the first section 110 is reduced and is lower than the pressure at the mist inlet 101, and the water mist can flow from the high-pressure mist inlet 101 to the low-pressure first section 110 and then is sprayed out through the mist outlet 102.

The second effect is as follows: because the air duct 200 can input the air flowing from the air outlet 201 toward the mist outlet 102 into the first section 110, the air flowing from the air duct 200 can be mixed with the water mist in the first section 110, and the temperature of the air entering from the air duct 200 can affect the temperature of the water mist in the mixing process, specifically, when the heating assembly 400 is started to work, the air entering into the first section 110 from the air duct 200 is heated, and then the air mist can be heated after being mixed with the water mist of the first section 110, and finally the hot water mist is sprayed out through the mist outlet 102, it should be noted that no heating device is arranged in the atomizing cavity 11a, the water mist directly output from the atomizing cavity 11a is cold mist, and the water mist is finally hot mist output after being mixed with the heated air output from the air duct 200; when the heating unit 400 is turned off and not operated, the air entering the first section 110 through the air duct 200 is cold air, so that the water mist sprayed from the mist outlet 102 is also cold water mist. No matter through heating element 400 heating gas in wind channel 200, still through the gas after the heating at first section 110 internal heating water smoke, can both the rapid heating to predetermineeing the temperature, also can be when heating element 400 closes, because heating element 400 no longer heats gas, and then can be fast change cold water smoke into by the hot water smoke of blowout, and then make humidifying equipment in this embodiment can be according to the hot fog or the cold fog of demand quick adjustment to the required state, the user need not to wait almost, user experience is better.

The third effect is that: the air flow in the air duct 200 enters the first section 110 after being output from the air outlet 201 and flows towards the direction of the mist outlet 102, but does not flow towards the mist inlet 101, which means that the air flow in the air duct 200 flows according to a predetermined path after flowing out from the air duct 200, so that a short air flow path can be realized, in addition, because the air flow flowing out from the air duct 200 does not flow towards the direction of the mist inlet 101, it indicates that the air flow does not flow into the atomizing cavity 11a, and does not move in the atomizing cavity 11a, so that the air flow resistance caused by the movement of the air flow in the atomizing cavity 11a is reduced, and the mist outlet efficiency is higher; and because the gas in the air duct 200 is the heated gas, and the heated gas can not flow into the atomizing chamber 11a, can not cause the influence to the device in the atomizing chamber 11a because of the temperature rise in the atomizing chamber 11a, has guaranteed atomizing chamber 11a operational environment and working life. Further, water in the atomizing chamber 11a does not flow back into the air duct 200, so that corrosion of water to devices arranged in the air duct 200 is avoided.

As for the heating assembly 400, the heating assembly 400 is arranged in the air duct 200 or outside the water mist channel 100, specifically including three conditions, the first condition is that the heating assembly 400 is arranged in the air duct 200 and in the water mist channel 100; secondly, the heating assembly 400 is arranged in the air duct 200 and outside the water mist channel 100, and thirdly, the heating assembly 400 is arranged on the air duct 200 and outside the water mist channel 100. In the above three cases, the water mist in the water mist channel 100 is not directly deposited on the heating assembly 400, so that the possibility of dirt generation and water mist corrosion on the heating assembly 400 are greatly reduced, the service life of the heating assembly 400 is prolonged, and the service life of the humidifying equipment in the embodiment is further prolonged.

Regarding the fan assembly 300, the fan assembly 300 is disposed in the air channel 200 or outside the water mist channel 100, specifically, the three conditions are also included, and in the first condition, the fan assembly 300 is disposed in the air channel 200 and located in the water mist channel 100; secondly, the fan assembly 300 is disposed in the air channel 200 and outside the water mist channel 100, and thirdly, the fan assembly 300 is disposed on the air channel 200 and outside the water mist channel 100. In the above three cases, the water mist in the water mist channel 100 is not directly deposited on the fan assembly 300, so that the possibility of dirt generation and water mist corrosion on the fan assembly 300 is greatly reduced, the service life of the fan assembly 300 is prolonged, the service life of the humidifying equipment in the embodiment is further prolonged, and the service life of the humidifying equipment in the embodiment is also prolonged.

It should be noted that, when the humidification apparatus in the present application has low requirements on the dirt prevention and corrosion prevention of the fan assembly 300, or the fan assembly 300 itself has good dirt prevention and corrosion prevention performance, the fan assembly 300 in this embodiment may not be disposed inside the air duct 200 or outside the water mist channel 100, such as being directly exposed inside the water mist channel 100.

For the first channel 210, the first channel 210 includes a wind guiding section 211 having an air outlet 201 and a transition section 212 for communicating the wind guiding section 211 with the second channel 220, the transition section 212 includes at least one flow restriction section 2121, the flow restriction section 2121 is a section where the transition section 212 is connected with the second channel 220, and in a direction vertical to and pointing from the mist inlet 101 to the mist outlet 102, one end of the flow restriction section 2121 near the wind guiding section 211 is lower than one end of the flow restriction section 2121 near the second channel 220. The mist of water is deposited into liquid water and then enters the second passage 220, which inevitably passes through the flow restriction 2121, and the flow restriction 2121 is higher near the end of the second passage 220, so that the flow restriction 2121 restricts the liquid water from entering the second passage 220 under the action of gravity.

Further, the wind guiding section 211 and the second channel 220 extend from the position connecting the transition section 212 toward the same side of the transition section 212. Because the second channel 220 and the air guiding section 211 extend from the position connected with the transition section 212 to the same side of the transition section 212, the fan assembly 300 or the heating assembly 400 installed in the second channel 220 or on the second channel 220 can be prevented from contacting with the water mist.

In order to further improve the water blocking effect, referring to fig. 3, 4 and 7, a water outlet 510 for discharging the deposited water mist is disposed on the air duct 200 at a position between the air outlet 201 and the heating assembly 400, the water outlet 510 is vertically disposed on a side wall surface of the air duct 200 away from the mist outlet 102, specifically, the water outlet 510 is disposed on the transition section 212, and preferably, a port of the water outlet 510, which is vertically lower than a port of the transition section 212 connected to the second passage 220 in a direction from the mist inlet 101 to the mist outlet 102, is located at a position below the transition section 212, so that a small amount of water mist entering the transition section 212 under special conditions can be discharged through the water outlet 510 without continuously flowing into the second passage 220, and thus the fan assembly 300 and the heating assembly 400 mounted on the second passage 220 or in the second passage 220 are prevented from contacting the water mist.

In order to prevent the deposited water from flowing through the water outlet 510, referring to fig. 7, the water outlet 510 further includes a water absorbing member 520 sealed on the water outlet 510, preferably, the water absorbing member 520 is a sponge, and the sponge can prevent the deposited water mist from flowing into the second channel 220, and can also prevent the gas from being discharged from the water outlet 510 to a great extent, thereby largely preventing the flow rate of the gas flowing out of the air outlet 201 from being reduced.

Further, referring to fig. 3 and 7, a liquid outlet 11p is formed at the bottom of the housing 10, and the water outlet 510 is communicated with the liquid outlet 11 p. Specifically, the housing 10 includes a drainage passage 11m communicating the liquid outlet 11p with the drainage port 510, and preferably, a water outlet of the drainage passage 11m is provided on a bottom wall of the base 11d to facilitate drainage of water.

It should be noted that, in the case of the first passage 210 having the flow restriction section 2121, the fan assembly 300 and the heating assembly 400 installed on or in the second passage 220 can be prevented from contacting the water mist regardless of the specific structure and layout orientation of the second passage 220.

In order to realize that the airflow in the air duct 200 enters the first section 110 after being output from the air outlet 201 and flows towards the direction of the mist outlet 102, the structure of the air duct 200 has at least two embodiments, the first embodiment is that the air duct 200 is partially arranged inside the water mist channel 100, and the second embodiment is that the air duct 200 is completely arranged outside the water mist channel 100.

First embodiment of structure of the air duct 200: the air duct 200 is partially disposed inside the water mist passageway 100.

Specifically, the air guiding section 211 is enclosed by an air guiding tube 213, and preferably, the air guiding tube 213 extends into the water mist channel 100, and the air outlet 201 faces the direction of the mist outlet 102. So that the flow direction of the gas flowing out from the air guiding section 211 is substantially the same as the flow direction of the water mist in the water mist channel 100, and the water mist sprayed from the mist outlet 102 can be along the extending direction of the first section 110.

Preferably, when the air duct 213 extends into the water mist channel 100, the extending direction of the whole water mist channel 100 is the same as the extending direction of the first section 110, and the air guiding section 211 is the same as the extending direction of the water mist channel 100. And water smoke passageway 100 and wind guide section 211 all are vertical direction setting, and the central axis of water smoke passageway 100 is the collinear with the central axis of wind guide section 211, and then make the vertical upwards blowout from fog-outlet 102 of the water smoke all around of guide duct, and the spraying effect is better.

When the air duct 213 extends into the water mist channel 100, referring to fig. 2 and 3, an accommodating member 11k provided at one side of the water mist channel 100 is protruded from the base 11d toward the side of the liquid storage tank 11, and the accommodating member 11k is hollow to form an air chamber 11 i; the casing 10 is further provided with a second air inlet 11j, and the second air inlet 11j is communicated with the air cavity 11 i. The duct forming the first channel 210 is a first duct 214, the duct forming the second channel 220 is a second duct 221, the second duct 221 is disposed in the air chamber 11i, so that the air chamber 11i is communicated with the air inlet 202 of the air duct 200, the base 11d further has a partition wall 11q disposed opposite to the mist inlet 101, and the partition wall 11q may be a bottom wall of the atomizing chamber 11a, or another wall surface that may separate the air chamber 11i from the atomizing chamber 11 a; the first pipe 214 partially passes through the partition wall 11q and extends into the interior of the water mist passage 100.

Specifically, the transition section 212 is U-shaped, the port of the transition section 212 connected to the air guiding section 211 and the port of the transition section 212 connected to the second channel 220 are substantially on the same horizontal plane, when the air guiding section 211 is vertically disposed, the port of the transition section 212 connected to the air guiding section 211 is horizontally disposed, and the port of the transition section 212 connected to the second channel 220 is also horizontally disposed, so as to facilitate connection with the air guiding drum 213 which is vertically disposed.

More specifically, the transition section 212 is fixed on the bottom wall of the atomization chamber 11a, a port of the transition section 212 connected to the air guide section 211 abuts against one wall surface of the bottom wall of the atomization chamber 11a, which is far away from the atomization chamber 11a, at this time, the partition wall 11q is the bottom wall of the atomization chamber 11a, a through opening corresponding to the port of the transition section 212 connected to the air guide section 211 is formed in the bottom wall of the atomization chamber 11a, the air guide section 211 is installed on the through opening, and the air guide section 211 and the transition section 212 in this embodiment can be conveniently installed on the housing 10. It should be noted that the bottom wall of the atomizing chamber 11a and the air guiding section 211 may also be integrally formed, so as to simplify the assembly difficulty and improve the sealing performance of the connection between the air guiding section 211 and the bottom wall.

Further, wind-guiding section 211 extends to the position department that is not too far away from fog outlet 102 in water smoke channel 100, and this position can be reachd according to the experiment, reachs the optimum length of first section 110 according to the experiment promptly, and specific thinking is to, with the gas that flows out through wind-guiding section 211 can heat water smoke to preset temperature in first section 110 as the prerequisite, reachs the minimum length of first section 110, and then reachs the optimum position of air outlet 201. Since the closer the air outlet 201 is to the mist outlet 102, the shorter the distance that the air flowing out of the air outlet 201 flows in the water mist channel 100, the smaller the loss kinetic energy, the higher the speed of the water mist and the air sprayed from the mist outlet 102, and the higher the water mist spray.

The shape of the air guide section 211 is not particularly limited, but is preferably a cylindrical shape for easy processing and assembly, and may be a square column shape, a rectangular column shape, or other shapes.

Second embodiment of the structure of the air duct 200: unlike the first embodiment, the air duct 200 of the second embodiment is completely disposed outside the water mist passage 100.

In order to reduce the cost increase caused by the long air duct 200, referring to fig. 8 and 9, in the second embodiment, the first channel 210 and the second channel 220 are both disposed outside the water mist channel 100, one end of the air guiding section 211 having the air outlet 201 is connected to the wall surface of the water mist channel 100, and the air outlet 201 is opened on the wall surface of the water mist channel 100. Because the air outlet 201 is located on the wall surface of the water mist channel 100, part of the air duct 200 does not need to be arranged in the water mist channel 100, so that the length of the first channel 210 does not need to be too long, the material cost for manufacturing the air duct 200 is reduced, and in addition, the flow rate of the air flowing out through the air duct 200 is larger and the spraying effect is better due to the reduction of the length of the air duct 200.

In the second embodiment, the air guiding section 211 is disposed obliquely to the water mist channel 100, and the angle formed by the air guiding section 211 and the first section 110 is greater than 90 °. Because the angle formed by the air guiding section 211 and the first section 110 is greater than 90 °, the air flow flowing out of the air guiding section 211 can flow to the mist outlet 102 through the first section 110.

Referring to fig. 8 and 9, unlike the first embodiment in which the first pipe 214 extends through the partition wall 11q to the inside of the water mist channel 100, the second embodiment in which the first pipe 214 passes through the receptacle 11k near the wall surface of the water mist channel 100 and is connected to the wall surface of the water mist channel 100. Specifically, the accommodating member 11k is provided with a through hole 11n, and the first pipe 214 passes through the through hole 11n and is connected with the wall surface of the water mist channel 100, so that the length of the first channel 210 is greatly reduced, and the speed of the gas flowing out through the first channel 210 is increased.

Preferably, the first section 110 is vertically arranged, preferably, the first section 110 is in a circular truncated cone shape, and the area near the air outlet 201 is smaller, so that the inner wall of the first section 110 is in an inclined state, the inner wall of the first section 110 has a guiding effect on the air flowing out of the air guiding section 211, and the direct impact between the air flowing out of the air guiding section 211 and the inner wall of the first section 110 is avoided.

Of course, the first segment 110 may also be disposed to be inclined with respect to the vertical direction, for example, the inclination angle of the first segment 110 is the same as or close to the inclination angles of the air guiding segments 211 with respect to the two vertical opposite directions, so that the air flowing out of the air guiding segments 211 is not blocked by the inner wall of the first segment 110, and the flow rate of the air flowing into the first segment 110 from the air guiding segments 211 is kept at the maximum.

It should be noted that: in this second embodiment, the water mist channel 100 further comprises a second section 120 for forming an air outlet 201.

The second segment 120 is cylindrical, prismatic, circular truncated cone or trapezoidal, and when the second segment 120 is circular truncated cone or trapezoidal, the area of the end of the second segment 120 facing the mist outlet 102 is larger than the area of the end far away from the mist outlet 102. When the second section 120 is cylindrical or prismatic, the air outlet 201 is formed on the second section 120, and the water mist moves vertically downwards due to the gravity during deposition, so that the water mist cannot enter the air duct 200 from the air outlet 201 under normal conditions, and the contact between the fan assembly 300 and the heating assembly 400 installed on the air duct 200 or in the air duct 200 and the water mist can be avoided; when the second section 120 is in a circular truncated cone shape or a trapezoidal shape and is vertically arranged, the area of the end of the second section 120 facing the mist outlet 102 is larger than the area of the end far away from the mist outlet 102, and by the same principle, the water mist is less likely to enter the air duct 200 from the air outlet 201.

In order to avoid the water mist entering the air duct 200 from the air outlet 201, and not to make the shape of the water mist channel 100 too complicated, a shielding edge (not shown in the drawings) is formed on the inner wall of the water mist channel 100 and extends inward at a position corresponding to the air outlet 201, specifically, the shielding edge is formed on the first section 110, that is, the shielding edge is disposed between the air outlet 102 and the air outlet 201, and the water mist can be prevented from entering the air outlet 201 during deposition.

In the above two embodiments, the first embodiment is to arrange a part of the air duct 200 inside the mist channel 100, so that the mist sprayed from the mist outlet 102 can be along the extending direction of the first segment 110, and the gas flowing out from the air outlet 201 can be prevented from directly colliding with the inner wall of the mist channel 100. The second embodiment is that the air duct 200 is completely disposed outside the water mist channel 100, and the length of the air duct 200 can be reduced to increase the flowing speed of the air while ensuring that the water mist sprayed from the mist outlet 102 can extend along the extending direction of the first section 110.

For the water mist channel 100, the water mist channel 100 is preferably in a circular truncated cone shape, and the area of one end of the mist outlet 102 of the water mist channel 100 is larger than that of one end of the mist inlet 101, after the atomizing cavity 11a generates mist, the area of one end of the mist inlet 101 of the water mist channel 100 is smaller, so that the pressure is easier to increase, the area of one end of the mist outlet 102 of the water mist channel 100 is larger, and the pressure is smaller relatively, so that the pressure difference between the mist outlet 102 and the mist inlet 101 of the water mist channel 100 is increased, and the mist spraying effect of the humidifying equipment is further improved.

It should be noted that the shape of the water mist channel 100 can be modified according to different embodiments, for example, in other embodiments, the water mist channel 100 is cylindrical, or the water mist channel 100 is truncated cone, or the first section 110 and other parts of the water mist channel 100 are different shapes.

Referring to fig. 1 and 4, a fragrance box 600 is detachably mounted on the base 11d, and fragrance holes for allowing fragrance in the fragrance box 600 to enter the atomization chamber 11a are formed in the base 11d, although the shape of the fragrance holes is not limited, and the fragrance holes are formed above a preset water level in the atomization chamber 11a to prevent water in the atomization chamber 11a from flowing out of the fragrance holes.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
