Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a humidifying device. Background Art

[0002] In the related art, a humidifier that can emit hot mist usually heats the hot water added to the humidifier through a heating component. This solution requires heating the water before hot mist can be emitted, and the user needs to wait for a certain period of time. Some humidifiers in the related art heat the water mist by placing the heating component in the water mist channel. Although the hot mist is emitted at a relatively fast speed, water will remain on the heating component, which will cause dirt or mold and corrosion over time. Summary of the Invention

[0016] As an embodiment of the present invention, the first section and the second channel extend on the same side of the first channel.

[0017] As an embodiment of the present invention, a drain outlet is provided on the air duct for discharging the deposited water mist. The drain outlet is located on the side wall of the first channel away from the mist outlet in the vertical direction, and a liquid outlet is provided at the bottom of the shell, and the drain outlet is connected to the liquid outlet.

[0018] As an embodiment of the present invention, a water absorbing member is sealed on the drain outlet.

[0019] As an embodiment of the present invention, the heating component includes a heat conductive plate and a heating film. The heat conductive plate includes a sleeve with two ends passing therethrough and a plurality of fins extending inward from the inner wall of the sleeve. The heating film is arranged on the sleeve, and the internal space of the sleeve forms a channel for the gas in the air duct to flow through.

[0030] The humidifying device in this embodiment has an air outlet connected to the water mist channel, so the gas flowing in from the air duct can be mixed with the water mist in the first section in the first section. In addition, since the air duct can input the gas flowing from the air outlet toward the mist outlet into the first section, after the water mist and gas in the first section flow out through the mist outlet, the pressure in the first section decreases and is lower than the pressure at the mist inlet, so that the water mist will flow from the high-pressure mist inlet to the low-pressure first section, and then be sprayed out through the mist outlet.

DETAILED DESCRIPTION

[0042] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] Please refer to Figures 1-9 The embodiment of the present invention provides a humidifying device, which mainly achieves the purpose of humidification by spraying. Therefore, the humidifying device in this embodiment can also be other devices that use the spray principle to achieve the purpose of humidification.

[0046] In one embodiment, the humidifying device includes a housing 10, an atomizing chamber 11a disposed in the housing 10, a water mist channel 100, an air duct 200, a fan assembly 300, and a heating assembly 400. The water mist channel 100 is disposed in the housing 10 and has a mist inlet 101 communicating with the atomizing chamber 11a for taking in water mist and a mist outlet 102 communicating with the outside world for discharging mist, and the mist inlet 101 and the mist outlet 102 are communicated with each other; the air duct 200 is disposed in the housing 10 and has an air outlet 201 communicating with the water mist channel 100 and an air inlet 202 communicating with the outside world for taking in air, and the air outlet 201 is located on the extension path of the water mist channel 100 and is placed at the mist inlet 101. 01 and the mist outlet 102; the fan assembly 20 is used to make the gas flow from the air inlet to the air outlet 201; the heating assembly 400 is arranged on the extension path of the air duct 200, and can heat the gas flowing from the air duct 200 to the water mist channel 100; the water mist channel 100 includes a first section 110 from the air outlet 201 to the mist outlet 102, and the air duct 200 is configured so 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. As for the shell 10, the shell 10 includes a base 11d and a liquid storage tank 11, and the liquid storage tank 11 is arranged on the base 11d. An atomizing chamber 11a is provided in the base 11d, and the atomizing device 12 is located in the atomizing chamber 11a and can atomize the water in the atomizing chamber 11a into water mist. The liquid storage tank 11 has a liquid storage chamber 11b.

[0047] More specifically, the liquid storage tank 11 includes a liquid storage tank upper shell 11e and a liquid storage tank bottom wall 11f. The liquid storage tank bottom wall 11f is clamped between the base 11d and the liquid storage tank upper shell 11e. The liquid storage tank bottom wall 11f is covered on the base 11d and enclosed with the base 11d to form an atomization chamber 11a. The liquid storage tank upper shell 11e is covered on the liquid storage tank bottom wall 11f and enclosed with the liquid storage tank bottom wall 11f to form a liquid storage chamber 11b.

[0048] Please refer to Figure 3 Atomizing chamber 11a is adjacent to liquid storage chamber 11b, which can be used to hold additional water. A water hole 11c is provided on the bottom wall 11f of the liquid storage tank, connecting liquid storage chamber 11b and atomizing chamber 11a. When the water level in atomizing chamber 11a falls below a preset value, the water in liquid storage chamber 11b flows into atomizing chamber 11a through water hole 11c. When the water level in atomizing chamber 11a reaches the preset height, the water in liquid storage chamber 11b no longer flows through water hole 11c to add water to atomizing chamber 11a. The addition of liquid storage chamber 11b prevents the water in the humidifier from being sprayed out too quickly, while also preventing excessive water from being held in atomizing chamber 11a, which would increase the difficulty of atomization.

[0049] Furthermore, when the humidifier is operating normally, the liquid storage chamber 11b is located above the atomizing chamber 11a to facilitate the flow of water in the liquid storage chamber 11b to the atomizing chamber 11a. Of course, the liquid storage chamber 11b can also be located to the side of the atomizing chamber 11a, and the water in the liquid storage chamber 11b can be transported to the atomizing chamber 11a by a water pump or other device.

[0050] Please refer to Figure 3 To control the flow of water hole 11c, the humidifier further includes a float 13 disposed within atomizing chamber 11a and a sealing member 14 for sealing water hole 11c. Sealing member 14 and float 13 are interlocked. When the water level within atomizing chamber 11a reaches a preset position, float 13 drives sealing member 14 to seal water hole 11c. When the water level within atomizing chamber 11a does not reach the preset position, a gap remains between sealing member 14 and water hole 11c. Float 13 ensures that the water level within atomizing chamber 11a is consistently maintained at the preset value, achieving optimal spray quality.

[0051] It should be noted that the structure of the housing 10 is only one of many embodiments of the housing 10 in the embodiments of the present invention.

[0052] As for the water mist channel 100, as described above, the water mist channel 100 is arranged in the shell 10 and is connected to the atomization chamber 11a, so that the water mist generated in the atomization chamber 11a can be sprayed out through the water mist channel 100. Specifically, the water mist channel 100 has a mist inlet 101 connected to the atomization chamber 11a and a mist outlet 102 connected to the outside world for mist discharge, and the mist inlet 101 and the mist outlet 102 are connected to each other.

[0053] More specifically, the water mist channel 100 is provided in the liquid storage tank 11 and extends from the side where the base 11d is located toward the side away from the base 11d. The mist outlet 102 is opened on the liquid storage tank 11. The water mist in the atomization chamber 11a enters the water mist channel 100 from the mist inlet 101 and is sprayed out through the mist outlet 102.

[0054] The housing 10 is provided with a first air inlet 11g connecting the outside with the atomizing chamber 11a. Air can be input from the outside into the atomizing chamber 11a through the first air inlet 11g, thereby maintaining the pressure in the atomizing chamber 11a within a certain range, so that the water mist in the atomizing chamber 11a can enter the water mist channel 100.

[0055] Furthermore, an air vent 11h communicating with the atomizing chamber 11a is provided on the base 11d. The air vent 11h is arranged on the base 11d and on the same side as the atomizing chamber 11a. The air vent 11h is communicated with the first air inlet 11g. The air vent 11h is located above a preset water level, thereby preventing water in the atomizing chamber 11a from entering the air vent 11h.

[0056] Preferably, the first air inlet 11 g is provided on the bottom wall of the base 11 d , and may also be provided on the side wall of the base 11 d or other locations of the housing 10 .

[0057] For duct 200, please refer to Figure 3 As shown, the upper air duct 200 is arranged in the shell 10, and the air duct 200 has an air outlet 201 connected to the water mist channel 100 and an air inlet 202 for taking in air. The air outlet 201 is located on the extension path of the water mist channel 100, and the air outlet 201 is located between the mist inlet 101 and the mist outlet 102. The fan assembly 300 is used to make the gas flow from the air inlet 202 to the air outlet 201, thereby generating wind in the air duct 200, and the heating assembly 400 can heat the gas in the air duct 200 flowing into the water mist channel 100, so that the wind flowing from the air duct 200 to the water mist channel 100 is hot air.

[0058] The water mist channel 100 includes a first section 110, which is the portion of the water mist channel 100 from the air outlet 201 to the mist outlet 102. The airflow within the air channel 200, after exiting the air outlet 201, enters the first section 110 and flows toward the mist outlet 102, rather than toward the mist inlet 101. The cooperation between the first section 110 and the air channel 200 can achieve at least three specific effects, namely the first effect, the second effect, and the third effect.

[0059] The first effect: the air duct 200 inputs gas flowing from the air outlet 201 toward the mist outlet 102 into the first section 110, that is, the gas in the air duct 200 continues to flow from the air outlet 201 toward the mist outlet 102 after entering the first section 110, thereby driving the water mist in the first section 110 to flow rapidly from the air outlet 201 toward the mist outlet 102, and finally sprayed out through the mist outlet 102, thereby reducing the pressure in the first section 110 and lowering it to be lower than the pressure at the mist inlet 101, so that the water mist will flow from the high-pressure mist inlet 101 to the low-pressure first section 110, and then sprayed out through the mist outlet 102.

[0060] The second effect: Since the air duct 200 can input the gas flowing from the air outlet 201 toward the mist outlet 102 into the first section 110, the gas flowing in from the air duct 200 can be mixed with the water mist in the first section 110. During the mixing process, the temperature of the gas entering from the air duct 200 can affect the temperature of the water mist. Specifically, when the heating component 400 is turned on, the gas entering the first section 110 from the air duct 200 is heated gas, and then after mixing with the water mist from the first section 110, the water mist can be heated and finally sprayed out through the mist outlet 102. It should be noted that there is no heating device in the atomizing chamber 11a. The water mist directly output from the atomizing chamber 11a is cold mist, which is finally output as hot mist after mixing with the heated gas output from the air duct 200; when the heating component 400 is turned off and not working, the gas entering the first section 110 from the air duct 200 is cold gas, so that the water mist sprayed from the mist outlet 102 is also cold water mist. Whether the gas is heated in the air duct 200 by the heating component 400, or the water mist is heated in the first section 110 by the heated gas, it can be quickly heated to the preset temperature. When the heating component 400 is turned off, the heating component 400 no longer heats the gas, and thus the hot water mist can be quickly converted into cold water mist. Therefore, the humidification device in this embodiment can be quickly adjusted to the required state of hot mist or cold mist according to demand, and the user almost does not need to wait, and the user experience is better.

[0061] The third effect: the airflow 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. This means that the airflow in the air duct 200 will flow along a predetermined path after flowing out of the air duct 200, and a shorter airflow path can be achieved. In addition, since the airflow flowing out of the air duct 200 will not flow toward the mist inlet 101, it means that the airflow will not flow into the atomizing chamber 11a, nor will it flow within the atomizing chamber 11a, thereby reducing the airflow resistance caused by the flow of air within the atomizing chamber 11a, thereby making the atomization efficiency higher; and since the gas in the air duct 200 is heated gas, and the heated gas will not flow into the atomizing chamber 11a, the temperature increase in the atomizing chamber 11a will not affect the devices in the atomizing chamber 11a, thereby ensuring the working environment and working life of the atomizing chamber 11a. Furthermore, the water in the atomizing chamber 11 a will not flow back into the air duct 200 , thereby preventing the water from corroding the components disposed in the air duct 200 .

[0062] The heating assembly 400 is disposed within the air duct 200 or outside the water mist passage 100. Specifically, there are three scenarios: first, the heating assembly 400 is disposed within the air duct 200 and within the water mist passage 100; second, the heating assembly 400 is disposed within the air duct 200 and outside the water mist passage 100; and third, the heating assembly 400 is disposed on the air duct 200 and outside the water mist passage 100. In all three scenarios, the water mist within the water mist passage 100 will not directly deposit on the heating assembly 400, significantly reducing the likelihood of dirt and water mist corrosion on the heating assembly 400, thereby extending the service life of the heating assembly 400 and, in turn, the humidification device of this embodiment.

[0063] Regarding the fan assembly 300, the fan assembly 300 is disposed within the air duct 200 or outside the water mist passage 100. Specifically, there are three situations: first, the fan assembly 300 is disposed within the air duct 200 and within the water mist passage 100; second, the fan assembly 300 is disposed within the air duct 200 and outside the water mist passage 100; and third, the fan assembly 300 is disposed on the air duct 200 and outside the water mist passage 100. In the above three situations, the water mist within the water mist passage 100 will not be directly deposited on the fan assembly 300, greatly reducing the possibility of dirt and water mist corrosion on the fan assembly 300, extending the service life of the fan assembly 300, and thereby extending the service life of the humidifier device in this embodiment.

[0064] It should be noted that when the humidification equipment in this application does not have high requirements for the anti-fouling and anti-corrosion properties of the fan assembly 300, or the fan assembly 300 itself has good anti-fouling and anti-corrosion properties, the fan assembly 300 in this embodiment may also not be arranged in the air duct 200 or outside the water mist channel 100, such as being directly exposed in the water mist channel 100.

[0065] In this embodiment, the fan assembly 300 and the heating assembly 400 are preferably arranged outside the water mist channel 100 .

[0066] Since the cooperation of the water mist channel 100, the air duct 200, the fan assembly 300 and the heating assembly 400 can bring the above beneficial effects, the structures of the water mist channel 100, the air duct 200, the fan assembly 300 and the heating assembly 400 are further described in detail below.

[0067] For duct 200, please refer to Figure 3 as well as Figure 8The air duct 200 includes a first channel 210 having an air outlet 201 and a second channel 220 communicating with the first channel 210. The second channel 220 is located outside the water mist channel 100 and is used to install the fan assembly 300 and the heating assembly 400. Since the second channel 220 is located outside the water mist channel 100, it can prevent the water mist from settling in or on the second channel 220 due to gravity, thereby preventing the water mist from directly depositing on the fan assembly 300 and the heating assembly 400. Furthermore, the first section 110 and the second channel 220 of the water mist channel 100 extend on the same side of the first channel 210, indicating that the first section 110 and the second channel 220 are arranged side by side, further reducing the risk of water mist in the water mist channel being deposited in the second channel 220 and corroding the components in the second channel 200.

[0068] For the second channel 220 , the fan assembly 300 and the heating assembly 400 may be installed in the second channel 220 , or the second channel 220 may be enclosed by the heating assembly 400 .

[0069] In a specific embodiment, the fan assembly 300 and the heating assembly 400 are installed in the second channel 220 .

[0070] Preferably, the second channel 220 is arranged vertically or obliquely, and the port where the second channel 220 connects to the first channel 210 is farther from the mist outlet 102 in the vertical direction than the air inlet 202. The air inlet 202 is formed at one end of the second channel 220 away from the first channel 210. The fan assembly 300 is arranged in the second channel 220 at one end close to the air inlet 202. The heating assembly 400 is arranged in the second channel 220 and is located between the fan assembly 300 and the port where the second channel 220 connects to the first channel 210. The fan assembly 300 can allow gas to flow from the air inlet 202 to the port where the second channel 220 connects to the first channel 210. By arranging the fan assembly 300 and the heating assembly 400 in the second channel 220, water mist can be effectively prevented from contacting the fan assembly 300 and the heating assembly 400, thereby preventing the fan assembly 300 and the heating assembly 400 from generating dirt and corrosion. By arranging the second channel 220 vertically or obliquely, the direction of the gas flowing out of the second channel 220 can be made vertically downward or obliquely downward, so as to further prevent water mist from being deposited on the fan assembly 300 and the heating assembly 400 .

[0071] In another specific embodiment, the second channel 220 is enclosed by a heating assembly 400, and the fan assembly 300 is mounted on one end of the air inlet 202 of the second channel 220. Specifically, the heating assembly 400 includes a heat conducting sheet 410 and a heating film 420. The heating film 420 is attached to the heat conducting sheet 410 to conduct heat to the heat conducting sheet 410.

[0072] In this embodiment, the heat conductive sheet 410 includes a sleeve 411 with two ends extending therethrough and a plurality of fins 412 extending inward from the inner wall of the sleeve 411. The heating film 420 is sleeved on the sleeve 411. The internal space of the sleeve 411 forms a channel for the gas in the air duct 200 to flow through, and the channel is the second channel 220. The fan assembly 300 is installed on one end of the second channel 220 close to the air inlet 202 so that the gas can flow into the first channel 210 through the second channel 220. The fins 412 can improve the thermal conductivity, so that the gas passing through the second channel 220 can be quickly heated. In this embodiment, the material cost required for the production of the second channel 220 is also saved. Since the fan assembly 300 and the heating assembly 400 are installed outside the air duct 200, they are easier to install.

[0073] The first channel 210 includes an air guide section 211 having an air outlet 201 and a transition section 212 for connecting the air guide section 211 and the second channel 220. The transition section 212 includes at least one flow-restricting section 2121, which is the section connecting the transition section 212 and the second channel 220. In a vertical direction from the mist inlet 101 to the mist outlet 102, the end of the flow-restricting section 2121 near the air guide section 211 is lower than the end of the flow-restricting section 2121 near the second channel 220. Therefore, when the water mist, after being deposited as liquid water, wants to enter the second channel 220, it must pass through the flow-restricting section 2121. The end of the flow-restricting section 2121 near the second channel 220 is higher. Under the action of gravity, the flow-restricting section 2121 can restrict the liquid water from entering the second channel 220.

[0074] Furthermore, the air guide section 211 and the second channel 220 extend from the position where they are connected to the transition section 212 toward the same side of the transition section 212. Since the second channel 220 and the air guide section 211 extend from the position where they are connected to the transition section 212 toward the same side of the transition section 212, the fan assembly 300 or the heating assembly 400 installed in or on the second channel 220 can be prevented from coming into contact with water mist.

[0075] To further improve the water blocking effect, please refer to Figure 3 、 Figure 4 as well as Figure 7A drain outlet 510 for discharging the deposited water mist is provided on the air duct 200 between the air outlet 201 and the heating component 400. The drain outlet 510 is located on the side wall of the air duct 200 away from the mist outlet 102 in the vertical direction. Specifically, the drain outlet 510 is provided on the transition section 212, and preferably, the drain outlet 510 is lower than the port connecting the transition section 212 and the second channel 220 in the vertical direction from the mist inlet 101 to the mist outlet 102. Through the drain outlet 510, a small amount of water mist that enters the transition section 212 under special circumstances can be discharged when passing through the drain outlet 510, and will not continue to flow into the second channel 220, thereby avoiding contact between the fan assembly 300 and the heating assembly 400 installed on or in the second channel 220 and the water mist.

[0076] To prevent the sedimented water from flowing through the drain 510, please refer to Figure 7 , and also includes a water absorbing member 520 that blocks the drain outlet 510. Preferably, the water absorbing member 520 is a sponge. The sponge can prevent water mist from being deposited and flowing into the second channel 220, and can also largely prevent gas from being discharged from the drain outlet 510, thereby largely avoiding a reduction in the flow rate of the gas flowing out of the air outlet 201.

[0077] For further information, please refer to Figure 3 as well as Figure 7 The housing 10 has a liquid outlet 11p at the bottom thereof, and the drain port 510 is connected to the liquid outlet 11p. Specifically, the housing 10 includes a drainage channel 11m connecting the liquid outlet 11p with the drain port 510. Preferably, the outlet of the drainage channel 11m is disposed on the bottom wall of the base 11d to facilitate water discharge.

[0078] It should be noted that when the first channel 210 has a flow limiting section 2121, no matter what the specific structure and layout orientation of the second channel 220 is, the fan assembly 300 and the heating assembly 400 installed on or in the second channel 220 can be prevented from contacting the water mist.

[0079] In order to ensure that the airflow in the air duct 200 is output from the air outlet 201, enters the first section 110 and flows toward the mist outlet 102, there are at least two implementation methods for the structure of the air duct 200. The first implementation method is that the air duct 200 is partially arranged inside the water mist channel 100, and the second implementation method is that the air duct 200 is completely arranged outside the water mist channel 100.

[0080] A first embodiment of the structure of the air duct 200 : the air duct 200 is partially disposed inside the water mist channel 100 .

[0081] Specifically, the air guide section 211 is formed by surrounding the air guide tube 213. Preferably, the air guide tube 213 extends into the water mist passage 100, and the air outlet 201 faces the direction of the mist outlet 102. As a result, the flow direction of the air flowing out of the air guide section 211 is substantially the same as the flow direction of the water mist in the water mist passage 100, so that the water mist sprayed from the mist outlet 102 can be along the extension direction of the first section 110.

[0082] Preferably, when the air guide tube 213 extends into the water mist channel 100, the entire water mist channel 100 extends in the same direction as the first section 110, and the air guide section 211 extends in the same direction as the water mist channel 100. Furthermore, the water mist channel 100 and the air guide section 211 are both arranged vertically, with the central axis of the water mist channel 100 and the central axis of the air guide section 211 being aligned. This allows the water mist around the air guide tube to be evenly sprayed vertically upward from the mist outlet 102, resulting in a better spray effect.

[0083] When the air guide tube 213 extends into the water mist channel 100, refer to Figure 2 as well as Figure 3 As shown, a receiving member 11k is protruded from the side of the base 11d facing the liquid storage tank 11 and is arranged on one side of the water mist channel 100. The receiving member 11k is hollow inside, forming an air chamber 11i. A second air inlet 11j is also provided on the housing 10, and the second air inlet 11j is connected to the air chamber 11i. The pipe forming the first channel 210 is a first pipe 214, and the pipe forming the second channel 220 is a second pipe 221. The second pipe 221 is arranged in the air chamber 11i to connect the air chamber 11i with the air inlet 202 of the air duct 200. The base 11d also has a partition wall 11q arranged opposite the mist inlet 101. The partition wall 11q can be the bottom wall of the atomizing chamber 11a, or other wall that can separate the air chamber 11i from the atomizing chamber 11a. The first pipe 214 partially passes through the partition wall 11q and extends into the interior of the water mist channel 100.

[0084] Specifically, the transition section 212 is U-shaped, and the port connecting the transition section 212 and the air guide section 211 and the port connecting the transition section 212 and the second channel 220 are basically on the same horizontal plane. When the air guide section 211 is set vertically, the port connecting the transition section 212 and the air guide section 211 is set horizontally, and the port connecting the transition section 212 and the second channel 220 is also set horizontally, so as to facilitate connection with the vertically set air guide tube 213.

[0085] More specifically, the transition section 212 is fixed to the bottom wall of the atomizing chamber 11a, and the port where the transition section 212 is connected to the air guide section 211 abuts against a wall of the bottom wall of the atomizing chamber 11a away from the atomizing chamber 11a. At this time, the partition wall 11q is the bottom wall of the atomizing chamber 11a. A through opening corresponding to the port connected to the transition section 212 and the air guide section 211 is provided on the bottom wall of the atomizing chamber 11a. The air guide section 211 is installed on the through opening. 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 guide section 211 can also be an integrally formed arrangement to simplify the assembly difficulty and improve the sealing performance of the connection between the air guide section 211 and the bottom wall.

[0086] Furthermore, the air guide section 211 extends to a position within the water mist channel 100 that is not too far from the mist outlet 102. This position can be determined experimentally, that is, the optimal length of the first section 110 can be determined experimentally. The specific idea is to determine the minimum length of the first section 110, based on the premise that the gas flowing out of the air guide section 211 can heat the water mist to a preset temperature within the first section 110, and then determine the optimal position of the air outlet 201. Because the closer the air outlet 201 is to the mist outlet 102, the shorter the distance the gas flowing out of the air outlet 201 flows within the water mist channel 100, the less kinetic energy is lost, and the higher the speed of the water mist and gas ejected from the mist outlet 102, the higher the water mist spray.

[0087] As for the shape of the air guide section 211, there is no specific limitation, and it is preferably cylindrical to facilitate processing and assembly. Of course, it can also be a square column or a rectangular column or other shapes.

[0088] Second embodiment of the air duct 200 structure: Different from the first embodiment, the air duct 200 of the second embodiment is completely arranged outside the water mist channel 100.

[0089] To reduce the cost increase caused by the air duct 200 being too long, please refer to Figure 8 as well as Figure 9 In this second embodiment, both the first channel 210 and the second channel 220 are disposed outside the water mist channel 100. One end of the air guide section 211, which includes an air outlet 201, is connected to the wall of the water mist channel 100. The air outlet 201 is located on the wall of the water mist channel 100. Because the air outlet 201 is located on the wall of the water mist channel 100, there is no need to dispose part of the air duct 200 within the water mist channel 100. Consequently, the length of the first channel 210 does not need to be excessive, reducing the material cost of manufacturing the air duct 200. Furthermore, the reduced length of the air duct 200 increases the flow rate of the gas flowing out of the air duct 200, resulting in a better spray effect.

[0090] In the second embodiment, the air guide section 211 is tilted relative to the water mist channel 100, and the angle between the air guide section 211 and the first section 110 is greater than 90 degrees. Since the angle between the air guide section 211 and the first section 110 is greater than 90 degrees, the air flowing out of the air guide section 211 can flow through the first section 110 to the mist outlet 102.

[0091] Please refer to Figure 8 as well as Figure 9 Unlike the first embodiment, in which the first conduit 214 extends through the partition wall 11q into the interior of the water mist passage 100, in the second embodiment, the first conduit 214 passes through the wall of the receiving member 11k near the water mist passage 100 and is interconnected with the wall of the water mist passage 100. Specifically, the receiving member 11k is provided with a through-hole 11n, through which the first conduit 214 passes and connects with the wall of the water mist passage 100. This significantly reduces the length of the first passage 210 and increases the velocity of the gas flowing out of the first passage 210.

[0092] Preferably, the first section 110 is arranged vertically, and preferably the first section 110 is in the shape of a cone, and the area near the air outlet 201 is smaller, so that the inner wall of the first section 110 is inclined, so that the inner wall of the first section 110 has a guiding effect on the gas flowing out of the air guide section 211, avoiding direct impact between the gas flowing out of the air guide section 211 and the inner wall of the first section 110.

[0093] Of course, the first section 110 can also be tilted relative to the vertical direction, for example, the inclination angle of the first section 110 is the same as or similar to the inclination angles of the air guide section 211 in two relative directions relative to the vertical, so that the gas flowing out of the air guide section 211 will not be blocked by the inner wall of the first section 110, so that the flow rate of the gas flowing from the air guide section 211 to the first section 110 is maintained at the maximum state.

[0094] It should be noted that in the second embodiment, the water mist channel 100 further includes a second section 120 for forming an air outlet 201 .

[0095] The second section 120 is cylindrical, prismatic, truncated cone, or stepped, and when the second section 120 is truncated cone or stepped, the area of ​​the end of the second section 120 facing the mist outlet 102 is larger than the area of ​​the end away from the mist outlet 102. When the second section 120 is cylindrical or prismatic, since the air outlet 201 is formed on the second section 120, the water mist moves vertically downward due to gravity when deposited, and thus, under normal circumstances, it will not enter the air duct 200 from the air outlet 201, thereby preventing the fan assembly 300 and the heating assembly 400 installed on or in the air duct 200 from coming into contact with the water mist. When the second section 120 is truncated cone or stepped and is vertically arranged, since the area of ​​the end of the second section 120 facing the mist outlet 102 is larger than the area of ​​the end away from the mist outlet 102, based on the same principle, it is even less likely that the water mist will enter the air duct 200 from the air outlet 201.

[0096] In order to prevent water mist from entering the air duct 200 from the air outlet 201 and to avoid making the shape of the water mist channel 100 too complicated, a shielding edge (not shown in the figure) is formed on the inner wall of the water mist channel 100 at a position corresponding to the air outlet 201 and extending inward. Specifically, the shielding edge is formed on the first section 110, that is, the shielding edge is provided between the mist outlet 102 and the air outlet 201. The shielding edge can also prevent water mist from entering the air outlet 201 when it is deposited.

[0097] In the two aforementioned embodiments, the first embodiment partially disposes the air duct 200 inside the water mist channel 100, allowing the water mist ejected from the mist outlet 102 to follow the extension direction of the first section 110, thereby preventing the gas flowing out of the air outlet 201 from directly colliding with the inner wall of the water mist channel 100. The second embodiment disposes the air duct 200 completely outside the water mist channel 100. While ensuring that the water mist ejected from the mist outlet 102 can follow the extension direction of the first section 110, the length of the air duct 200 can be reduced to increase the gas flow rate.

[0098] For the water mist channel 100, the water mist channel 100 is preferably in a truncated cone shape, and the area of ​​one end of the mist outlet 102 of the water mist channel 100 is larger than the area of ​​one end of the mist inlet 101. When the atomization chamber 11a generates mist, since the area of ​​one end of the mist inlet 101 of the water mist channel 100 is relatively small, it is easier to increase the pressure, and the area of ​​one end of the mist outlet 102 of the water mist channel 100 is relatively large, the pressure will be relatively smaller, thereby increasing the pressure difference between the mist outlet 102 and the mist inlet 101 of the water mist channel 100, further improving the spray effect of the humidification equipment of the present application.

[0099] It should be noted that the shape of the water mist channel 100 can be appropriately modified according to different implementation methods. For example, in some other embodiments, the water mist channel 100 is cylindrical, or the water mist channel 100 is truncated cone-shaped, or the first section 110 and other parts of the water mist channel 100 are of different types of shapes.

[0100] Please refer to Figure 1 as well as Figure 4 The base 11d is detachably mounted with an aromatherapy box 600. The base 11d is provided with an aromatherapy hole for the aroma in the aromatherapy box 600 to enter the atomization chamber 11a. Of course, the shape of the aromatherapy hole is not limited. The aromatherapy hole is provided above a preset water level in the atomization chamber 11a to prevent the water in the atomization chamber 11a from flowing out of the aromatherapy hole.

[0101] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
