Figure 4 The humidification device of the utility model is schematically shown along Figure 3 Schematic diagram of the cross-sectional structure along line AA in FIG.
[0034] In some embodiments of the present disclosure, the humidifying device includes a housing 10 , in which a base 20 , an air outlet grille 30 , and a humidifying unit 40 are disposed.
[0035] like Figure 1A and Figure 1B As shown, the housing 10 of the humidifier can be, for example, a rectangular parallelepiped structure, and a ventilation duct T1 is provided on the housing 10, which runs from the rear side of the housing 10 to the front side of the housing, so that part of the indoor air can flow from the rear side of the housing 10 to the front side of the housing 10 through the ventilation duct T1, or flow from the front side of the housing 10 to the rear side of the housing. The ventilation duct T1 is, for example, a square channel.
[0036] In some optional embodiments of the present disclosure, the shell can be a structure of any shape, and the ventilation duct inside the shell can also be various shapes designed according to actual ventilation needs, so as to transport air from one side of the ventilation duct to the other side of the ventilation duct.
[0037] like Figure 2 and Figure 3 As shown, the housing 10 contains a base 20 , an air outlet grille 30 and a humidifying unit 40 .
[0038] like Figure 1B and Figure 2 As shown, the base 20 is close to the bottom of the shell 10, and the base 20 is provided with an air inlet 21 for air to enter, so that when the humidifying device is working, air enters the base through the air inlet 21.
[0039] The humidifier 100 is provided with an air supply channel T2, which includes the air inlet 21. The humidifier 100 also includes an air supply unit 50 for driving air to enter from the air inlet 21 to circulate in the air supply channel T2.
[0040] The air outlet grille 30 is disposed on the top surface of the base 20 and connected to the air supply portion 50. The air outlet grille 30 includes a plurality of air guide portions 31 that are spaced apart and arranged in parallel. For example, the air guide portions 31 extend in the vertical direction. There is a certain interval between each of the air guide portions 31. The air guide portions 31 are arranged in parallel with each other. The plurality of air guide portions 31 are arranged in a row along the length direction of the base 20. The air outlet grille 30 includes a first side S1 and a second side S2. The first side S1 and the second side S2 are arranged opposite to each other. For example, the first side S1 of the air outlet grille may be toward the front end of the humidifier 100, and the second side S2 may be toward the rear end of the humidifier.
[0041] The air guide 31 is provided with an air outlet 32 for blowing out air, and a part of the air supply channel T2 is provided in the air guide 31. That is, the inside of the air guide 31 is a hollow structure, and the hollow structure constitutes a part of the air supply channel T2. One end of the air supply channel T2 is connected to the air inlet 21, and the other end of the air supply channel T2 is connected to the air outlet 32. After entering the air inlet 21, the air is discharged from the air outlet 32 through the air supply channel T2.
[0042] Exemplarily, the air outlet 32 faces the front end of the humidifying device, that is, the air outlet 32 faces the first side S1 of the air outlet grille.
[0043] like Figure 4 As shown, the wind guide portion 31 is in a long strip structure and is arranged in the vertical direction. The wind guide portion 31 includes a first end D1 away from the base 20 and a second end D2 close to the base 20.
[0044] like Figure 2 As shown, the humidifying device 100 also includes a humidifying part 40, which includes a mist outlet 41 for discharging water mist, and the mist outlet 41 is arranged on a side of the air outlet grille 30 away from the base 20. For example, the mist outlet 41 is arranged at the top of the air outlet grille 30, and the mist outlet 41 and the air outlet 32 face the first side S1 of the air outlet grille.
[0045] like Figure 2 and Figure 3 As shown, the humidifying unit 40 includes a humidifier 401 and a humidifying pipe 402 .
[0046] The humidifier 401 is arranged on the side of the housing 10 and on both sides of the air outlet grille 30 to generate water mist. For example, two humidifiers 401 are arranged, respectively on both sides of the housing and on the second side of the air outlet grille.
[0047] A humidifying pipe 402 is provided on each humidifier 401 , and the humidifying pipe 402 connects the humidifier 401 with the mist outlet 41 , so as to discharge the water mist generated by the humidifier 401 from the mist outlet 41 .
[0048] For example, two mist outlets 41 are provided, and each mist outlet 41 is connected to each humidifier through a humidification pipe 402. The mist outlets 41 are respectively located at the top of the air outlet grille 30 and are respectively close to the two side edges of the air outlet grille 30, so as to evenly spread the water mist to the first side of the air outlet grille, thereby forming a better visual effect.
[0049] The humidifying pipe 402 includes an extension pipe 4021 extending from the second side S2 toward the first side S1 , and a height of the extension pipe 4021 on the second side S2 is smaller than a height of the extension pipe 4021 on the first side S1 .
[0050] For example, the mist outlet 41 is located on the extension pipe 4021 of the first side S1, and the extension pipe 4021 is inclined downward from the first side S1 to the second side S2. Thus, condensation water formed at the mist outlet 41 will be guided from the humidification pipe 402 to the humidifier 401 along the inclined direction of the mist outlet 41, thereby preventing water droplets from falling at the mist outlet 41.
[0051] In other optional embodiments of the present disclosure, the number of mist outlets, the number of humidification pipes and the number of humidifiers can be selectively set according to actual humidification needs. The embodiments of the present disclosure do not specifically limit the number of mist outlets, the number of humidification pipes and the number of humidifiers.
[0052] like Figure 2 and Figure 4 As shown, a mist guide channel W for water mist circulation is provided between the air guide parts 31 arranged at intervals, that is, the outer walls of the two air guide parts arranged at intervals constitute the mist guide channel W, and the mist guide channel W includes a first mist guide channel W1 away from the base 20 and a second mist guide channel S2 close to the base 20. That is, the first mist guide channel W1 is arranged on the upper side of the air outlet grille 30, and the second mist guide channel W2 is arranged on the lower side of the air outlet grille 30, and the first mist guide channel W1 and the second mist guide channel W2 are respectively used to guide the water mist to different positions.
[0053] When the humidifier is in working state, the humidifying part 40 generates water mist, that is, the water mist is discharged from the mist outlet 41, and the air enters the air supply channel T2 from the air inlet 21 and is discharged toward the first side S1 of the air outlet grille 30 through the air outlet 32. When the air is discharged toward the first side S1 of the air outlet grille 30 through the air outlet 32, the air around the air outlet 32 is affected by the flow of the air discharged from the air outlet, resulting in a negative pressure area Z formed on the second side S2 of the air outlet grille 30, such as Figure 4 As shown in the dotted box in FIG. 1 , the pressure of the negative pressure zone Z on the second side S2 is higher than the pressure of other areas, thereby causing the air in the surrounding area to flow toward the negative pressure zone Z on the second side S2.
[0054] Since the first mist guide channel W1 is provided on the upper side of the air outlet grille 30, the water mist discharged from the mist outlet 41 enters the negative pressure zone Z through the first mist guide channel W1 along with the flow of air, and since the air in the negative pressure zone Z is driven to move by the air blown out of the air outlet 32, the water mist in the negative pressure zone Z is discharged from the negative pressure zone Z to the first side S1 of the air outlet grille 30 through the second mist guide channel W2, as shown in FIG. Figure 4 As shown by the dotted curve in the figure, the water mist is fully mixed with the air discharged from the outlet.
[0055] In the embodiment of the present disclosure, the first mist guide channel W1 is located near the first end D1 of the air guide portion, the air outlet 32 is arranged on the second end D2 of the air guide portion, and the second mist guide channel W2 is located closer to the second end D2 than the first mist guide channel W1.
[0056] After the water mist is discharged from the mist outlet 41, it is evenly diffused along the water mist baffle 11 in the arrangement direction of the air guide 31. Under the action of gravity, the water mist falls toward the base, forming a water mist curtain at the front end of the humidifier. Since the air outlet 32 is arranged on the second end D2 of the air guide 31, the wind blowing toward the first side will not appear on the first end D1 of the air guide 31, so that the falling water mist will not be carried away by the wind blown out of the air outlet 32. In the process of the water mist slowly falling, when the water mist reaches the first mist guide channel W1, after entering the negative pressure zone Z through the first mist guide channel W1, the water mist continues to fall in the direction close to the base 20 under the action of gravity, and because the wind speed in the negative pressure zone Z is relatively low, the water mist can fall to a position close enough to the base 20. When the water mist falls to the area of the second end D2 of the air guide 31 where the air outlet 32 is located, the water mist is discharged from the second side S2 to the first side S1 of the air outlet grille 30 through the second mist guide channel W2, so that the water mist is fully mixed with the air at the air outlet.
[0057] In some embodiments of the present disclosure, the air outlet 32 is configured as a long strip-shaped opening extending along the length direction of the air guide portion 31. The long strip-shaped opening can cause the air discharged from the air outlet to generate a greater disturbance to the surrounding air, thereby promoting the formation of a negative pressure zone and improving the conduction capacity of the mist guide channel to water mist.
[0058] In some optional embodiments, the shape of the air outlet can be adjusted according to the actual air outlet capacity to meet different requirements of air-water mist mixing capacity.
[0059] In some embodiments of the present disclosure, the air outlet grille 30 further includes an air guide fixing member 33 .
[0060] The air guide fixing member 33 is disposed on a side of the air guide 31 away from the base 20, and is used to fix the multiple air guides 31, for example, to fix the multiple air guides along the arrangement direction, so as to ensure the stability of the air guide. The number of air guide fixing members 33 and the number of air guides fixed by each air guide fixing member can be adjusted according to actual needs. For example, in a specific embodiment, each air guide fixing member can fix four air guides arranged at intervals.
[0061] The ventilation duct T1 arranged on the shell 10 points from the second side S2 of the air outlet grille 30 to the first side S1 of the air outlet grille 30, and the air outlet grille 30 covers the ventilation duct T1, that is, the negative pressure zone Z is located in the ventilation duct T1 and at the second side S2 of the air outlet grille 30.
[0062] Figure 5 A partial enlarged view of the humidifying device of the utility model at the water mist baffle is schematically shown.
[0063] like Figure 5 As shown, the housing 10 further includes a water mist baffle 11 .
[0064] The water mist baffle 11 is disposed on the opposite side of the mist outlet 41 so that the water mist discharged from the mist outlet 41 is evenly diffused in the arrangement direction of the air guide portion 31 .
[0065] The water mist baffle 11 and the other side walls of the shell 10 form a water mist groove 111, so that the water mist discharged from the mist outlet 41 can be diffused along the side of the air outlet grille under the action of the water mist baffle, and the height of the water mist baffle 11 can be selected to be smaller, so that the water mist can form a better free fall effect on the first side of the air outlet grille, thereby improving the aesthetics of the humidifier.
[0066] Figure 6 The schematic diagram of the structure of the air supply part 50 , the sterilization part 101 and the adding part 102 of the humidification device 100 of the present invention in the base 20 is shown schematically.
[0067] like Figure 4 and Figure 6 As shown, the air guide portion 31 is connected to the air inlet through a bend. An air supply portion 50 is provided in the base, one end of the air supply portion 50 is connected to the bend, and the air inlet of the air supply portion 50 is connected to the air inlet 21. The air supply portion 50 is used to drive the air at the air inlet 21 to circulate in the air supply channel, so that the air entering the air inlet is discharged through the air outlet 32 after passing through the bend and the air supply duct T2.
[0068] The air supply unit 50 can control the flow speed of the air in the air supply duct T2, thereby controlling the air outlet speed of the air outlet 32, so that the user can adjust it according to actual needs.
[0069] like Figure 6As shown, a sterilization unit 101 is also provided in the base 20 for sterilizing the air in the air supply channel T2. For example, a filtering component and / or a disinfecting component is provided in the sterilization unit 101, thereby sterilizing the air in the air supply channel.
[0070] The base 20 is also provided with an adding portion 102, which is arranged on the upstream side of the air supply portion and is used to release additives into the air in the air supply channel. For example, the released additives may be perfume, incense, or other substances that need to be released into the air.
[0071] like Figure 4 As shown, the housing 10 further includes a first air outlet baffle 12 .
[0072] The first air outlet baffle 12 is close to the second end D2 of the air guide portion, and is used to block at least a portion of the air discharged from the air outlet 32, that is, the air cannot be blown out from a portion close to the second end, so that the wind cannot be discharged from the air outlet close to the base. The position of the first air outlet baffle 12 can be adjusted in height according to actual needs, so as to control the height of the air and water mist discharged from the air outlet from the base.
[0073] In an optional embodiment of the present disclosure, a plant decoration area is set in front of the shell. In this case, the first air outlet baffle can be set at the air outlet opposite to the plant decoration area to meet the adjustment requirements of the air outlet position.
[0074] In another optional embodiment, in order to increase the wind speed and make the wind blow toward the upper body of the human body, the first air outlet baffle may also be arranged at the air outlet opposite to the lower body of the human body.
[0075] In other embodiments of the present disclosure, the air outlet is arranged on the first end and the second end of the air guide, that is, the air outlet is arranged along the length direction of the air guide. The second mist guide channel is closer to the second end than the first mist guide channel. The shell also includes a second air outlet baffle, which is arranged at the first end of the air guide, for shielding at least a portion of the air distributed from the air outlet, that is, the second air outlet plate shields at least a portion of the air of the air outlet at the first end, thereby preventing the air blown out from the first end from affecting the water mist in the first mist guide channel. According to this embodiment, when the air outlet is arranged at the first end and the second end of the air guide, and the second air outlet baffle is arranged at the same time, the air will not be discharged from the first end, and on the basis of achieving full mixing of air and water mist, the overall aesthetics of the humidifier can also be improved.
[0076] In some embodiments of the present disclosure, the humidifying device 100 further includes a water flow portion 103. The water flow portion 103 is disposed on at least one side of the air outlet grille 30 and has the same extension length direction as the air guide portion.
[0077] As shown in FIG1 , the water flow portion 102 includes two, which are symmetrically arranged on both sides of the air outlet grille. The water flow portion 103 is extended in the vertical direction. The water flow portion 103 includes a water flow surface 1031 for water to flow through. The direction of the water flow surface 1031 is the same as the direction of the air outlet 32. A circulation pump is arranged in the water flow portion 103, which is used to circulate the water at the bottom of the water flow portion in the vertical direction into the top of the water flow portion, and the water circulates in the water flow portion to form a water curtain or waterfall, thereby improving the aesthetics of the humidifier.
