[0044] The air supply unit 7 is arranged inside the housing 1, on the downstream side of the humidifying unit 2, and is arranged opposite to the humidifying filter 22. The air supply unit 7 is used to drive air to enter the housing 1 from the air inlet of the rear wall 12, drive the air entering the housing 1 to flow through the humidifying unit 2, and after being humidified by the humidifying unit 2, discharge it from the air outlet of the top wall 13. The air supply unit 7 is provided with a rib protruding towards the humidifying unit 2 for fixing the humidifying unit 2.

[0045] The air supply unit 7 includes a volute, a fan blade and a motor. The volute is in the shape of a spiral-expanded snail, provided with a suction port and a blow-out port.

The fan blade includes a hub and a fan blade group. The motor realizes the driving function and is used to drive the multiple fan blades of the fan blade group to rotate.

[0046] The water drainage frame 3 is arranged on the top of a fixed frame 21. The water drainage frame 3 is in the shape of a hollow cuboid and is formed by enclosing four side plates and a bottom plate. In this embodiment, the bottom plate is the top plate body 211 of the fixed frame 21. In other embodiments, a bottom plate can be additionally arranged on the top plate body 211 of the fixed frame 21. The water drainage frame 3 has a length direction. The two side plates consistent with the length direction are respectively the first side plate 31 and the second side plate 32, and the first side plate 31 and the second side plate 32 are opposite to each other. The two side plates consistent with the width direction are respectively the third side plate and the fourth side plate, and the third side plate and the fourth side plate are opposite to each other. The inner wall surfaces of the four side plates and the inner wall surface of the bottom plate enclose a cuboid shape to form a water storage area.

[0047] The first side plate 31 is close to the air supply unit 7, and the second side plate 32 is close to the rear wall 12 of the housing 1, that is, the first side plate 31 is far from the air inlet side of the humidifying filter 22, and the second side plate 32 is close to the air inlet side of the humidifying filter 22. The water inlet hole 34 is arranged on the first side plate 31. The water inlet hole 34 can be arranged in the middle area of the first side plate 31, or can be arranged in the end area of the first side plate 31. In this embodiment, restricted by other components inside the housing 1, the water inlet hole 34 is arranged close to the end of the first side plate 31. That is, along the length direction of the first side plate 31, the two ends of the first side plate 31 are respectively the left end and the right end, and the water inlet hole 34 can be arranged close to the left end or close to the right end. In this embodiment, the water inlet hole 34 is located at the right end of the first side plate 31.

[0048] The water inlet hole 34 is arranged close to the end of the first side plate 31, and the liquid entering the water drainage frame 3 from the water inlet hole 34 flows along the length direction of the water drainage frame 3 from one end of the water drainage frame 3 towards the other end, ensuring that the liquid can fully fill the entire area inside the water drainage frame 3.

[0049] The water outlet frame 3 is provided with a plurality of water outlet holes 33, and at least one water outlet hole 33 is arranged in the end area of the water outlet frame 3, that is, the left end area or the right end area of the water outlet frame 3. Specifically, the plurality of water outlet holes 33 are arranged on the bottom plate. That is, the water outlet holes 33 are arranged at the left end and / or the right end of the bottom plate. The number of the water outlet holes 33 is set according to actual requirements, and the water outlet holes 33 penetrate through the bottom plate of the water outlet frame 3. When the humidifying unit 2 is the same as or substantially the same as the length of the water outlet frame 3, the water outlet holes 33 are opposite to the ends of the humidifying unit 2. The ends of the humidifying filter screen 22 refer to the left edge area at the top of the left end and the right edge area at the top of the right end of the humidifying filter screen 22. The water outlet holes 33 at the left end on the bottom plate are opposite to the left edge area of the humidifying filter screen 22, and the water outlet holes 33 at the right end on the bottom plate are opposite to the right edge area of the humidifying filter screen 22, so as to increase the humidified area of the humidifying filter screen 22.

[0050] Liquid flows into the water outlet frame 3 and flows towards the humidifying filter screen 22 along the plurality of water outlet holes 33, which can fully wet the entire area of the humidifying filter screen 22, ensure that the humidifying filter screen 22 can be in full contact with the liquid, and fully humidify the air flowing through the humidifying filter screen 22, thereby being beneficial to improving the humidifying effect of the humidifying device.

[0051] In the embodiment of the present disclosure, the bottom of the water outlet frame 3 is provided with a plurality of water outlet holes 33, and the liquid entering the water outlet frame 3 flows towards the humidifying unit 2 along the plurality of water outlet holes 33. The liquid can be in full contact with the humidifying filter screen 22, so that the air flowing through the humidifying filter screen 22 can be fully humidified, thereby being beneficial to improving the humidifying effect of the humidifying device.

[0052] As Figure 4 shown, in this embodiment, the plurality of water outlet holes 33 are arranged at intervals along the extending direction of the water outlet frame 3, that is, the plurality of water outlet holes 33 are arranged at intervals along the length direction of the bottom plate. The right end of the bottom plate is the first end, and the left end of the bottom plate is the second end. The water inlet hole 34 is close to the right end of the bottom plate. In this embodiment, adjacent two water outlet holes 33 are arranged at intervals, and the interval distances are the same. Preferably, the plurality of water outlet holes 33 can be arranged in a straight line. In other embodiments, the water outlet holes 33 can also be arranged in two columns side by side on the bottom plate to increase the water outlet speed, thereby increasing the humidifying amount. The radial dimensions of the plurality of water outlet holes 33 are arranged in an increasing manner from the first end to the second end direction, that is, the smaller the radial dimension of the water outlet hole 33 closer to the water inlet hole 34, and the larger the radial dimension of the water outlet hole 33 farther from the water inlet hole 34. In this embodiment, the radial dimensions of the water outlet holes 33 increase in turn from the side close to the water inlet hole 34 to the side far from the water inlet hole 34.

[0053] The water outlet hole 33 of this embodiment is arranged in a polygonal shape formed by combining a semi-circular shape and a rectangular shape. That is, the water outlet hole 33 is formed by combining a semi-circular through hole 331 and a rectangular through hole 332 that communicate with each other. The radial dimensions of the water outlet hole 33 include a first radial dimension and a second radial dimension. The first radial dimension is the size of the diameter of the semi-circular through hole 331, and the second radial dimension is the maximum distance between the hole wall of the semi-circular through hole 331 and the hole wall of the rectangular through hole 332. The water outlet hole 33 is arranged in a combination of a semi-circular shape and a rectangular shape, which can make the inflowing liquid flow into the humidifying filter screen 22 along the sharp corners of the rectangle, avoiding the liquid flowing into the water outlet hole 33 from forming water droplets and then flowing into the humidifying filter screen 22.

[0054] The shape of the water outlet hole 33 can also be set to other polygonal shapes. For example, the water outlet hole 33 is formed by combining a triangular through hole and a rectangular through hole that communicate with each other. In other embodiments, the water outlet hole 33 can be circular, elliptical, square or other shapes.

[0055] As Figure 4 shown, along the axial direction of the water outlet hole 33, extending from the end far from the humidifying unit 2 towards the end close to the humidifying unit 2, the water outlet hole 33 is tapered, that is, the cross-sectional area of the water outlet hole 33 gradually becomes smaller. The hole wall surface of the water outlet hole 33 is an inclined guiding surface 333, and the guiding surface 333 can reduce the surface tension of the liquid, enabling the liquid flowing into the water outlet frame 3 to flow towards the humidifying filter screen 22 more quickly.

[0056] As Figure 2 、 Figure 3 and Figure 4 shown, the water outlet frame 3 further includes a partition plate 35, a water distribution space 36 and a water distribution channel 37.

[0057] The partition plate 35 is arranged between two adjacent water outlet holes 33, protruding and extending from the first side plate 31 of the water outlet frame 3 towards the second side plate 32 of the water outlet frame 3, forming a water distribution space 36 and a water distribution channel 37. In this embodiment, the height of the partition plate 35 is lower than the height of the first side plate 31. In other embodiments, the height of the partition plate 35 can be the same as the height of the first side plate 31. In other embodiments, the partition plate 35 can be arranged between two adjacent groups of water outlet holes 33, and each group of water outlet holes 33 includes two or more water outlet holes 33. The number of partition plates 35 is set according to actual needs. In this embodiment, the water outlet frame 3 includes 5 partition plates 35, and the partition plate 35 close to the water inlet hole 34 is the first partition plate.

[0058] The water diversion space 36 is a space formed by enclosing with two adjacent partition plates 35 and the first side plate 31. The water diversion space 36 enables each water outlet hole 33 to have a corresponding independent water storage area. In this embodiment, the water outlet frame 3 includes 6 water diversion spaces 36. The water diversion space 36 close to the water inlet hole 34 is the first water diversion space, and the first water diversion space is formed by enclosing with the first side plate 31, the third side plate and the first partition plate of the water outlet frame 3. The second water diversion space is formed by enclosing with the first partition plate, the second partition plate and the first side plate 31.

[0059] There is a gap between the partition plate 35 and the second side plate 32. A water diversion channel 37 is formed between the ends of multiple partition plates 35 and the second side plate 32. The water diversion channel 37 is close to the air inlet side of the humidifying filter screen 22. Through the water diversion channel 37, the liquid entering from the water inlet hole 34 can reach the water outlet hole 33 far from the water inlet hole 34 after passing through the water diversion channel 37.

[0060] Each water diversion space 36 is provided with a water outlet hole 33, and the water outlet hole 33 is close to the water diversion channel 37 side. In other embodiments, the water outlet hole 33 can be arranged in the middle of the water diversion space 36.

[0061] The water inlet hole 34 is used to enable the liquid to enter the water outlet frame 3. The water inlet hole 34 is arranged on the first side plate 31, and one end of the water inlet hole 34 is connected to the liquid supply pipe adapter. In other embodiments, the water inlet hole 34 can be arranged in the middle of the water outlet frame 3, that is, the water inlet hole 34 is located in the middle area of the first side plate 31. The water inlet hole 34 of this embodiment is arranged in the first water diversion space.

[0062] Figure 6 It is a schematic diagram of the position of the water collection part of the humidifying device according to the embodiment of the present invention; Figure 7 It is a schematic diagram of the structure of the water collection part of the humidifying device according to the embodiment of the present invention.

[0063] As Figure 6 and Figure 7 shown, the humidifying device further includes a water tank 4, a water pump and a water collection part 5.

[0064] The water tank 4 is in the shape of a six-sided cuboid and is located at the bottom of the humidifying device. It is used to store liquid and supply the liquid to the humidifying unit 2 so that the humidifying unit 2 can humidify the air flowing through.

[0065] The water pump is arranged in the water tank 4 and is used to pump the liquid in the water tank 4 into the water outlet frame 3.

[0066] The water collecting part 5 is disposed opposite to the lower part of the humidifying unit 2 and is close to the air inlet side. A water collecting tank 51 and a return hole 53 are formed on the water collecting part 5. The water collecting part 5 is disposed opposite to the lower part of the humidifying unit 2, that is, the water collecting part 5 is in contact with and closely adjacent to the side surface of the fixing frame 21 facing the air inlet, which means that one side wall of the water collecting part 5 is in contact with the bottom of the longitudinal reinforcing rib 215 of the fixing frame 21.

[0067] The length direction of the water collecting tank 51 is the same as that of the humidifying unit 2, and the length of the water collecting tank 51 is adapted to the length of the humidifying filter screen 22. The water collecting tank 51 is used for collecting the liquid dripping from the humidifying filter screen 22.

[0068] A return hole 53 is formed on the tank wall of the water collecting tank 51, and the return hole 53 is communicated with the water tank 4. The liquid flowing into the water collecting tank 51 flows into the water tank 4 after passing through the return hole 53.

[0069] The return hole 53 is disposed at the end of the water collecting tank 51, and the bottom of the water collecting tank 51 is inclined, that is, the depth of the water collecting tank 51 on the side close to the return hole 53 is greater than the depth of the water collecting tank 51 on the side far from the return hole 53. In this embodiment, the return hole 53 is located at the right end of the water collecting part 5.

[0070] As Figure 5 and Figure 7 shown, in this embodiment, the humidifying unit 2 further includes a plurality of reinforcing ribs. The reinforcing ribs include horizontal transverse reinforcing ribs 214 and vertical longitudinal reinforcing ribs 215. The two ends of the transverse reinforcing rib 214 are respectively connected to the two side plates 213 of the fixing frame 21. A plurality of fixing ribs 216 perpendicular to the transverse reinforcing rib 214 protrude from the transverse reinforcing rib 214, and the humidifying filter screen 22 is embedded in the fixing ribs 216. The longitudinal reinforcing rib 215 extends from the top of the humidifying filter screen 22 towards the bottom of the humidifying filter screen 22. The humidifying filter screen 22 is installed in the fixing frame 21. The plurality of transverse reinforcing ribs 214, the plurality of fixing ribs 216 and the plurality of longitudinal reinforcing ribs 215 are in contact with the humidifying filter screen 22, effectively preventing the humidifying filter screen 22 from slipping out of the fixing frame 21 and ensuring the stability of the humidifying filter screen 22.

[0071] As Figure 7As shown in the figure, in this embodiment, the water collection part 5 further includes a guiding rib 52. The guiding rib 52 is located in the water collection tank 51. The top surface of the guiding rib 52 is higher than the top surface of the water collection tank 51, that is, the height of the guiding rib 52 is greater than the depth of the water collection tank 51. The number of guiding ribs 52 is set according to actual requirements. When the number of guiding ribs 52 is one, one guiding rib 52 is disposed opposite to one of the longitudinal reinforcing ribs 215. When the number of longitudinal reinforcing ribs 215 and the number of guiding ribs 52 are both multiple, the multiple guiding ribs 52 are disposed opposite to the multiple longitudinal reinforcing ribs 215 one by one. In this embodiment, the bending angle of the guiding rib 52 is in an elliptical arc shape, so that when the humidifying filter screen 22 is installed, it slides in the direction of the trajectory line of the elliptical arc shape due to the inertia of force, avoiding the humidifying filter screen 22 from being inserted into the water collection part 5. In other embodiments, the guiding rib 52 may be rectangular.

[0073] As Figure 8 and Figure 9 shown, in this embodiment, the humidifying device further includes a liquid supply pipe 61 and a fixing part 62. One end of the liquid supply pipe 61 is connected to the water tank 4, and the other end of the liquid supply pipe 61 is provided with a liquid supply pipe adapter. The liquid supply pipe adapter is connected to the water inlet hole 34. The liquid supply pipe 61 is disposed on the side of the air supply unit 7 close to the humidifying unit 2. After the humidifying device is started, the water pump pumps the liquid in the water tank 4 into the liquid supply pipe 61, and the liquid flows along the liquid supply pipe 61 to the water inlet hole 34, further flowing into the lower water frame 3 and flowing to the humidifying filter screen 22 through a plurality of lower water holes 33.

[0074] The fixing part 62 is disposed in the housing 1 and is used for fixing the liquid supply pipe 61. The fixing part 62 is disposed close to the top of the housing 1 and is located on the side of the air supply unit 7 close to the humidifying unit 2.

[0075] In this embodiment, the fixing part 62 includes a first guiding groove 621 and a second guiding groove 622. The first guiding groove 621 and the second guiding groove 622 are communicated with each other. The first guiding groove 621 and the second guiding groove 622 are disposed on the wall surface of the air supply unit 7 close to the humidifying unit 2.

[0076] The first guiding groove 621 includes a connected first guiding section 6211, a second guiding section 6212, and a third guiding section 6213. The first guiding section 6211 is close to the vertical state, the third guiding section 6213 is close to the horizontal state, and the second guiding section 6212 is arc-shaped, which is used to achieve a smooth transition from the first guiding section 6211 to the third guiding section 6213. The liquid supply pipe 61 is stuck in the first guiding groove 621, and the outer surface of the liquid supply pipe 61 abuts against the groove wall surface of the first guiding groove 621, so that the liquid flowing through the liquid supply pipe 61 flows upward along the extending direction of the first guiding groove 621.

[0077] The second guiding groove 622 extends in the direction towards the water inlet hole 34, and one end of the second guiding groove 622 is connected to the first guiding groove 621. The second guiding groove 622 is inclined, and the inclination angle of the second guiding groove 622 is set according to actual requirements. The end of the second guiding groove 622 close to the water inlet hole 34 is higher than the end of the second guiding groove 622 close to the first guiding groove 621. The liquid supply pipe 61 is stuck in the second guiding groove 622, and the outer surface of the liquid supply pipe 61 abuts against the groove wall surface of the second guiding groove 622, so that the liquid flowing through the liquid supply pipe 61 flows upward along the inclined direction of the second guiding groove 622. In other embodiments, one end of the second guiding groove 622 is connected to the first guiding groove 621, and the other end of the second guiding groove 622 is close to the adapter of the liquid supply pipe 61.

[0078] The operation process of the humidifying device will be described in detail below.

[0079] When the humidifying device is started, the water pump is started, so that the liquid in the water tank 4 is sucked into the liquid supply pipe 61. The liquid flows upward through the liquid supply pipe 61 and flows into the lower water frame 3 above the humidifying unit 2 through the water inlet hole 34 provided in the first water distribution space. After the liquid enters the lower water frame 3, since the left end and the right end of the lower water frame 3 are both provided with water outlet holes 33, the liquid can flow into the left edge area or the right edge area of the humidifying filter screen 22 from the water outlet holes 33 at the left end or the right end of the lower water frame 3, thereby increasing the humidified area of the humidifying filter screen 22. The liquid in the lower water frame 3 flows towards the humidifying unit 2 along a plurality of water outlet holes 33, and the liquid can be in full contact with the humidifying filter screen 22, so that the air flowing through the humidifying filter screen 22 can be fully humidified, which is beneficial to improving the humidifying effect of the humidifying device.

[0080] Further, to solve the problem that the liquid cannot reach the end far from the water inlet hole 34, i.e., the left end of the water outlet frame 3. In this embodiment, a partition plate 35 and a water distribution channel 37 are further arranged in the water outlet frame 3. When the liquid reaches the water outlet frame 3, the liquid flows along the water distribution channel 37 from the end close to the water inlet hole 34 to the end far from the water inlet hole 34. When encountering the partition plate 35, the liquid enters the second water distribution space along the first partition plate. Since the flow rate of the liquid close to the water inlet hole 34 in the water distribution channel 37 is relatively fast, after a certain amount of liquid is stored in the second water distribution space, the liquid will flow into the third water distribution space along the second partition plate, and so on, so that an independent water storage area is formed in the area where each water outlet hole is located, ensuring that there is sufficient water pressure at the water outlet hole 33 far from the water inlet hole 34.

[0081] Further, since the radial dimension of the water outlet hole 33 closer to the water inlet hole 34 is smaller, and the radial dimension of the water outlet hole 33 farther from the water inlet hole 34 is larger, therefore, although the flow rate is fast in the second water distribution space, due to the pressure loss, the flow rate of the liquid flowing into the second water outlet hole is slower than that of the liquid flowing into the first water outlet hole. This embodiment is provided with six water outlet holes 33, and the flow area of each water outlet hole 33 is set according to the flow rate, and the flow area of the water outlet hole 33 closer to the water inlet hole 34 is smaller. The flow area of the water outlet hole 33 close to the water inlet hole 34 is small, and the flow rate of the liquid is fast; the flow area of the water outlet hole 33 far from the water inlet hole 34 is large, and the flow rate of the liquid is slow, thereby ensuring that the flow rate at each water outlet hole 33 is uniform, ensuring that different positions of the humidifying filter screen 22 can be evenly drenched, and ensuring good moisture permeability uniformity of the humidifying filter screen 22.

[0082] Further, when the liquid enters the water distribution space 36, it flows through the guiding surface 333 of the water outlet hole 33 at the same time, reducing the surface tension of the liquid. At the same time, the water outlet hole 33 is in a shape combined by a semi-circular shape and a rectangular shape, so that the flowing-in liquid flows into the humidifying filter screen 22 along the sharp corner of the rectangle, avoiding the formation of water droplets. Thus, the liquid can flow to the humidifying filter screen 22 more quickly, ensuring that the humidifying filter screen 22 is completely wetted, so as to ensure that the inhaled air can be completely in contact with the liquid, thereby increasing the relative humidity of the air and sending out the air with higher humidity through the air outlet, and further ensuring the humidifying effect.

[0083] Since the humidifying filter screen 22 has a high humidity, there is often liquid flowing out of the humidifying unit 2. The water collecting tank 51 of the water collecting part 5 collects the liquid flowing out of the humidifying unit 2, and the liquid enters the water tank 4 through the return hole 53, ensuring that the liquid will not overflow to other components of the humidifying device, especially the electrical components, ensuring that other components remain dry, and improving the safety of using the humidifying device.

[0084] The water collection part 5 faces and is closely adjacent to the lower part of the humidifying unit 2, making it difficult to generate gaps, ensuring that the inhaled air completely flows through the humidifying unit 2, thereby ensuring the humidifying capacity. Further, when the humidifying unit 2 is taken out and reinstalled into the housing 1, due to the guiding ribs 52 of the water collection part 5 protruding upward in an elliptical arc shape, the humidifying unit 2 slides along the trajectory line of the elliptical arc shape of the guiding ribs 52, enabling the easy installation of the humidifying unit 2 while avoiding the insertion of the humidifying unit 2 into the water collection part 5.

[0085] Furthermore, one end of the liquid supply pipe 61 is connected to the water tank 4, and the other end is connected to the liquid supply pipe adapter. There are peaks and valleys in the water section between the bent part of the liquid supply pipe 61 and the liquid supply pipe adapter, which easily causes air entrapment in this water section. Due to the air entrapment in this water section, each time the humidifying device is turned on, this part of the air needs to be discharged, resulting in noise when the humidifying device is turned on each time. When the flow rate or velocity of the water pump is too small, the air entrapment phenomenon will also cause the liquid in the water tank 4 not to be pumped into the lower water frame 3, resulting in the failure of the humidifying function. Therefore, in this embodiment, the liquid supply pipe 61 is fixed by the first guiding groove 621 and the second guiding groove 622, and the second guiding groove 622 is inclined, with a slope extending upward in the direction of the water inlet hole 34. When the liquid supply pipe 61 is fixed in the first guiding groove 621 and the second guiding groove 622, the liquid supply pipe 61 does not bend in a zigzag manner but forms a slope conducive to water supply, thereby eliminating the peaks and valleys generated by the bending of the liquid supply pipe 61, and thus eliminating the air entrapment phenomenon caused by the peaks and valleys, that is, eliminating the noise generated for discharging air after the humidifying device is turned on. In addition, it also avoids the phenomenon of inability to supply water due to air entrapment when the flow rate or velocity of the water pump is too small. Additionally, since the liquid supply pipe 61 is fixed in the fixing groove, the liquid in the liquid supply pipe 61 flows upward along the trajectory lines of the first guiding groove 621 and the second guiding groove 622, improving the smoothness of liquid flow and ensuring the reliable operation of the humidifying device.
