[0029] See also Figure 1-2The present invention proposes a humidification and purification device 100, which includes: a housing 10, on which an air outlet 11, a humidification air inlet 12 and a purification air inlet 13 are provided; an air supply duct 20, which is arranged in the housing 10 and communicated with the air outlet 11, and a fan assembly 21 is arranged in the air supply duct 20; a purification duct 30, which is arranged in the housing 10 and communicated with the purification air inlet 13, and a purification assembly 31 is arranged in the purification duct 30. The purification air duct 30 is connected with the air supply air duct 20, so that the external air is blown out from the air outlet 11 through the purification air inlet 13, the purification component 31, and the fan component 21 in sequence; the humidification air duct 40, the humidification air duct 40 is arranged in the shell 10 and is connected with the humidification air inlet 12, and a humidification component 41 is arranged in the humidification air duct 40. The humidification air duct 40 is connected with the air supply air duct 20, so that the external air is blown out from the air outlet 11 through the humidification air inlet 12, the humidification component 41, and the fan component 21 in sequence.

[0030] In this embodiment, the humidification and purification device 100 is used to humidify and / or purify the air in the indoor environment. Specifically, the shell 10 may include a first shell 14, a second shell 15 and a third shell 16. The first shell 14, the second shell 15 and the third shell 16 may be connected in sequence from top to bottom to form the shell 10. The first shell 14, the second shell 15 and the third shell 16 may also be connected in sequence from left to right or from right to left to form the shell 10. The shell 10 is a hollow structure. In one embodiment, the air outlet 11 is opened at the top of the first shell 14, the purification air inlet 13 is opened on the second shell 15, and the humidification air inlet 12 is opened on the third shell 16. The shell 10 may be a hollow column such as a hollow cylindrical shape or a hollow square column shape. The second shell 15 and the third shell 16 may be formed by a grille plate. The grille holes on the grille plate serve as the humidification air inlet 12 and the purification air inlet 13, thereby increasing the air intake of the humidification air inlet 12 and the purification air inlet 13.

[0031] In this embodiment, the air supply duct 20 is formed in the first shell 14, and the air supply duct 20 is connected to the air outlet 11, and the fan assembly 21 is arranged in the air supply duct 20; the purification duct 30 is formed in the second shell 15, and the purification assembly 31 is arranged in the purification duct 30, and the humidification duct 40 is formed in the third shell 16, and the humidification assembly 41 is arranged in the humidification duct 40. Since the purification duct 30 is connected to the purification air inlet 13 and the air supply duct 20, and the humidification duct 40 is connected to the humidification air inlet 12 and the air supply duct 20, the fan assembly 21 can pass through the purification duct 30 from the purification air inlet 13 to the purification air inlet 11. 3 sucks external air into the purification air duct 30, purifies it through the purification component 31, and blows it out from the air outlet 11. At the same time, the fan component 21 can also suck external air into the humidification air duct 40 from the humidification air inlet 12 through the humidification air duct 40, humidifies it through the humidification component 41, and blows it out from the air outlet 11. Therefore, this embodiment can simultaneously realize the functions of humidifying and purifying the air through the same humidification and purification device 100, thereby solving the problem of large space occupied by humidifiers and purifiers in the prior art, and the humidification and purification device 100 of the present application superimposes humidification and purification functions, and has richer air conditioning functions than the humidifiers and purifiers in the prior art.

[0032] See also Figure 2-3 Further, the purification air duct 30 is arranged between the air supply duct 20 and the humidification air duct 40, or the humidification air duct 40 is arranged between the air supply duct 20 and the purification air duct 30, and a first damper 50 movably connected to the shell 10 is arranged between the humidification air duct 40 and the purification air duct 30, and the first damper 50 moves relative to the shell 10 to connect or block the humidification air duct 40 and the purification air duct 30.

[0033] In one embodiment, the purification duct 30 may be directly connected to the air supply duct 20, and the humidification duct 40 is connected to the air supply duct 20 through the purification device, that is, the purification duct 30 also serves to connect the air supply duct 20 with the humidification duct 40. At this time, a first damper 50 movably connected to the shell 10 is provided between the humidification duct 40 and the purification duct 30, and the first damper 50 moves relative to the shell 10 to connect or block the humidification duct 40 and the purification duct 30. When the first damper 50 connects the purification duct 30 with the humidification duct 40 (such as Figure 2 As shown), the humidification and purification device 100 can simultaneously realize the humidification and purification functions. When the first air door 50 blocks the purification air duct 30 and the humidification air duct 40 (as shown Figure 3 As shown), the humidification and purification device 100 can independently realize the purification function. In this case, the humidification and purification device is equivalent to a purifier.

[0034] In another embodiment, the humidification duct 40 may be directly connected to the air supply duct 20, and the purification duct 30 is connected to the air supply duct 20 through the humidification duct 40, that is, the humidification duct 40 also serves to connect the air supply duct 20 with the purification duct 30. At this time, a first damper 50 movably connected to the housing 10 is provided between the humidification duct 40 and the purification duct 30, and the first damper 50 moves relative to the housing 10 to connect or block the humidification duct 40 and the purification duct 30. When the first damper 50 connects the purification duct 30 and the humidification duct 40, the humidification purification device 100 can simultaneously realize the humidification and purification functions. When the first damper 50 blocks the purification duct 30 and the humidification duct 40, the humidification purification device 100 can realize the humidification function alone. At this time, the humidification purification device 100 is equivalent to a humidifier. It can be understood that the humidification air duct 40 and the purification air duct 30 can be directly connected to the air supply air duct 20, so that the humidification and purification device 100 can always achieve humidification and purification functions at the same time.

[0035] In this embodiment, by changing the positions of the purification air duct 30 and the humidification air duct 40 and adding the first air door 50, the humidification and purification device 100 can simultaneously realize the humidification and purification functions or independently realize the humidification function or the purification function, thereby enriching the use scenarios of the humidification and purification device 100.

[0036] See also Figure 2-5 Furthermore, the humidification and purification device 100 also includes: a second damper 60, which is arranged between the purification air inlet 13 and the purification component 31 to selectively block or connect the air flow channel between the purification component 31 and the purification air inlet 13.

[0037] In this embodiment, the purification component 31 is directly connected to the air supply duct 20, and the humidification duct 40 is connected to the air supply duct 20 through the purification duct 30. When the first damper 50 and the second damper 60 are opened at the same time, the air flow channel between the purification component 31 and the purification air inlet 13 is connected, and the humidification duct 40 is also connected to the purification duct 30, so that the purification and humidification functions can be realized at the same time (such as Figure 2As shown), when the first damper 50 is opened and the second damper 60 is closed, the air flow channel between the purification component 31 and the purification air inlet 13 is connected, and the humidification air duct 40 is disconnected from the purification air duct 30, and the purification function can be realized separately (as shown in FIG. Figure 3 As shown in FIG. 1 ), when the first damper 50 is closed and the second damper 60 is opened, the air flow channel between the purification component 31 and the purification air inlet 13 is disconnected, and the humidification air duct 40 and the purification air duct 30 are opened, and the humidification function can be realized separately (as shown in FIG. 1 ). Figure 4 As shown), when the humidification and purification device 100 is turned off, when the first damper 50 and the second damper 60 are closed at the same time, the air flow channel between the purification component 31 and the purification air inlet 13 is disconnected, and the humidification air duct 40 and the purification air duct 30 are also disconnected to prevent external dust from entering the purification air duct 30.

[0038] It can be understood that the third damper (not shown) can also be provided, and the third damper is provided between the humidification air inlet 12 and the purification component 31 to selectively block or connect the air flow channel between the humidification component 41 and the humidification air inlet 12. At this time, the first damper 50 can be retained or removed; when the third damper and the second damper 60 are opened at the same time, the air flow channel between the purification component 31 and the purification air inlet 13 is connected, and the air flow channel between the humidification component 41 and the humidification air inlet 12 is also connected, and the purification and humidification functions can be realized at the same time. When the third damper is opened and the second damper 60 is closed, the air flow channel between the purification component 31 and the purification air inlet 13 is blocked. When the third damper is closed and the second damper 60 is opened, the air flow channel between the purification component 31 and the purification air inlet 13 is connected, and the air flow channel between the humidification component 41 and the humidification air inlet 12 is disconnected, so that the purification function can be realized alone. When the humidification and purification device 100 is turned off, when the third damper and the second damper 60 are closed at the same time, the air flow channel between the purification component 31 and the purification air inlet 13 is disconnected, and the air flow channel between the humidification component 41 and the humidification air inlet 12 is disconnected, so as to prevent external dust from entering the purification air duct 30 and the humidification air duct 40.

[0039] See also Figure 2-5 Furthermore, the first damper 50 and the second damper 60 are rotary dampers or folding dampers.

[0040] In this embodiment, the rotary damper can be arranged on the shell 10 through a driving member such as a motor 2123, and the rotary damper is driven to rotate by the motor 2123. Taking the first damper 50 as a rotary damper as an example, the first damper 50 includes at least an open position and a closed position during its rotation. In the open position, the first damper 50 has the least resistance to the air entering the purification air duct 30 from the humidification air duct 40. At this time, the humidified air in the humidification air duct 40 can enter the air supply duct 20 from the purification air duct 30 and be delivered from the air outlet 11.

[0041] In this embodiment, the foldable damper is composed of a plurality of stackable and unfoldable wind shields (not shown in the figure), each wind shield can be movably connected, and can be driven to move relative to each other by a driving member such as a motor 2123 and a transmission member such as a chain or a belt. The relative movement of each wind shield includes a stowed position and an unfolded position. Taking the second damper 60 as a foldable damper as an example, in the stowed position, each wind shield is stacked together to conduct the airflow channel between the purification component 31 and the purification air inlet 13. In the unfolded position, each wind shield is arranged in sequence to block the airflow channel between the purification component 31 and the purification air inlet 13.

At the same time, the air outlet 71 is closed by the first air door 50 to block the purification air duct 30 and the humidification air duct 40. The first air door 50 can be provided on the inner wall of the shell 10 by a driving member, and can also be provided on the air duct divider 70 by a driving member.

[0044] See also Figure 5 Furthermore, the purification component 31 includes: a support member 311, which is arranged on the air duct partition 70; a purification member (not shown), which is arranged between the purification air inlet 13 and the support member 311, and the purification member includes at least one of a HEPA filter 312, a formaldehyde net 313 and a plasma member 134.

[0045] In this embodiment, the support member 311 may have four fixed surfaces, and the four fixed surfaces may be used to fix the purification member.

[0046] See also Figure 4 , 6 Further, the humidification component 41 includes: a water storage member 411, the water storage member 411 is arranged in the humidification air duct 40, the water storage member 411, the shell 10 and the air duct partition 70 together form the humidification air duct 40 to connect the humidification air inlet 12 and the air outlet 71; an annular wet film 412, the annular wet film 412 is arranged in the water storage member 411, and the annular wet film 412 extends from the water storage member 411 to the humidification air duct 40 to humidify the air flowing through the humidification air duct 40.

[0047] In this embodiment, the water storage member 411 may be, for example, a water tank containing water for humidification. The water storage member 411 is disposed in the humidification air duct 40 and fixed on the base 161 of the third shell 16. A gap is left between the top of the water storage member 411 and the air duct partition 70 so that the air entering from the humidification air inlet 12 flows from the gap to the air outlet 71. That is, the water storage member 411, the shell 10 and the air duct partition 70 together form the humidification air duct 40. The bottom of the annular wet film 412 is disposed in the water storage member 411 to absorb moisture, and the top of the annular wet film 412 extends into the humidification air duct 40. The annular wet film 412 is annular and can humidify the air entering the humidification air duct 40 from all directions, thereby increasing the humidification amount of the air.

[0048] See also Figure 7 Further, the humidification component 41 includes: a water storage member 411, the water storage member 411 includes an annular bottom shell 4111, an annular outer shell 4112 and an annular inner shell 4113, the annular bottom shell 4111 is provided with a bottom shell opening 4114, an air inlet duct 162 is formed between the annular bottom shell 4111 and the base 161 of the shell 10, the annular outer shell 4112 is arranged on the outer edge of the annular bottom shell 4111, the top of the annular outer shell 4112 is connected to the air duct partition 70, the annular inner shell 4113 is arranged on the edge of the annular bottom shell opening 4114, and the top of the annular inner shell 4113 is sealed, and the annular inner shell A plurality of inner shell through holes (not shown) are provided on the side wall of 4113, and a water accommodating space is formed between the annular outer shell 4112 and the annular inner shell 4113; an annular wet film 412, the top of which is sealed, and the bottom of which is arranged in the water accommodating space, and an air outlet duct 163 is formed between the annular wet film 412 and the annular outer shell 4112, and between the top of the annular wet film 412 and the air duct partition 70, and the external air flows to the air outlet 71 in sequence through the humidification air inlet 12, the air inlet duct 162, the bottom shell opening 4114, the inner shell through hole, the annular wet film 412 and the air outlet duct 163.

[0049] In this embodiment, the water storage member 411 is a special-shaped water tank, and includes the annular bottom shell 4111, the annular outer shell 4112 and the annular inner shell 4113. The annular outer shell 4112 is arranged around the outer edge of the annular bottom shell 4111, and extends from the outer edge of the annular bottom shell 4111 to abut against the air duct partition 70 to form a seal, so as to prevent the air sucked from the humidification air inlet 12 from passing between the annular outer shell 4112 and the air duct partition 70; the annular bottom shell 4111 and the base of the housing 10 The annular bottom shell 4111 is provided with a plurality of inner shell through holes on the side wall of the annular inner shell 4113, so that the air in the bottom shell opening 4114 flows out from the inner shell through holes instead of flowing out from the annular bottom shell 4113. The water flows out from the top of the shell 4113. It can be understood that the inner shell through hole has a certain height compared with the annular inner shell 4113, so that the annular inner shell 4113 can store water. For example, the annular inner shell 4113 is opened at the upper half of the annular inner shell 4113, so that a water accommodating space is formed between the annular inner shell 4113 and the annular outer shell 4112; afterwards, since the bottom of the annular wet film 412 extends into the water and the top of the annular wet film 412 is closed, the air blown out from the inner shell through hole passes through the annular The side wall of the wet film 412 (rather than the top of the annular wet film 412) is humidified, and the humidified air flows into the space between the annular wet film 412 and the annular outer shell 4112, and then flows to the air outlet 71 through the space between the top of the annular wet film 412 and the air duct partition 70. That is, the humidified air passes through the air outlet duct 163 formed between the annular wet film 412 and the annular outer shell 4112, and between the top of the annular wet film 412 and the air duct partition 70, and flows to the air outlet 71. To summarize, the external air will flow to the air outlet 71 through the humidification air inlet 12, the air inlet duct 162, the bottom shell opening 4114, the inner shell through hole, the annular wet film 412 and the air outlet duct 163 in sequence. In this way, the flow path of the external air in the humidification air duct 40 can be extended, and the air can stay longer in the capped annular inner shell 4113 and the annular wet film 412, thereby extending the humidification time of the external air and increasing the humidification amount.
