[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] The following combination Figure 1-Figure 5 The air outlet assembly of a humidifier according to an embodiment of the present invention is described.

[0030] The humidifier air outlet assembly of the present embodiment includes a base 1 and a fan 2. The base 1 is provided with a first accommodating chamber 11 and an air guide channel 12. The air guide channel 12 includes a first channel 123 communicating with the first accommodating chamber 11. The fan 2 is installed in the first accommodating chamber 11 and includes an air outlet pipe 21. The cross-sectional outer contour of the air outlet pipe 21 matches the cross-sectional outer contour of the first channel 123, and the air outlet pipe 21 is inserted into the first channel 123.

[0031] According to the humidifier of the embodiment of the present invention, by setting the cross-sectional outer contour of the first channel 123 of the air guide channel 12 to match the cross-sectional outer contour of the air outlet pipe 21 on the fan 2, after the fan 2 is installed in the first accommodating chamber 11, the air outlet pipe 21 of the fan 2 is able to extend into the first channel 123. That is, on the basis of keeping the size of the air outlet pipe 21 of the fan 2 unchanged, the size of the first channel 123 can be widened so that the air outlet channel of the air outlet pipe 21 is not blocked by the base 1 and is directly connected to the air guide channel 12, thereby effectively ensuring the smoothness of the air outlet of the fan 2 and effectively improving the mist outlet efficiency of the humidifier.

[0032] It should be noted that the first accommodating chamber 11 is generally a sealed chamber, and the fan 2 is installed in the first accommodating chamber 11 to ensure its performance. The base 1 includes an upper shell and a lower shell, which are connected and surround the first accommodating chamber 11. In addition, the cross-sectional outer contour of the first channel 123 matches the cross-sectional outer contour of the air outlet duct 21 on the fan 2, which means that the cross-sectional outer contour of the first channel 123 is the same as the cross-sectional outer contour of the air outlet duct 21 on the fan 2. In some examples, the cross-sectional inner contour of the air outlet duct 21 and the cross-sectional outer contour of the first channel 123 are any one of a square, a circle, other regular polygons, and an irregular shape.

[0033] In some embodiments, as Figure 4 and Figure 5 As shown, the air guide channel 12 further includes a second channel 124 communicating with the first channel 123 , and the cross-sectional area of ​​the second channel 124 gradually decreases in a direction away from the first channel 123 .

[0034] After the outlet pipe 21 of the fan 2 is inserted into the first channel 123, the outlet channel within the outlet pipe 21 is directly connected to the second channel 124. By setting the cross-sectional area of ​​the second channel 124 to gradually decrease in the direction away from the first channel 123, the air discharged by the fan 2 will increase in speed when passing through the second channel 124 under the guidance of the inner wall surface of the second channel 124, without blocking the air flow and causing wind loss, thereby further improving the misting efficiency of the humidifier. In addition, this arrangement also effectively reduces the size of the portion of the base 1 that forms the second channel 124, preventing it from being too large and increasing the manufacturing cost of the humidifier.

[0035] For example, the cross-sectional outer contours of the second channel 124 and the first channel 123 are both any one of square, circle, other regular polygons and irregular shapes, and the inner wall surface of the second channel 124 is an upwardly tapered arc surface.

[0036] It should be noted that after the fan 2 is installed in the first accommodating chamber 11 , the air outlet pipe 21 of the fan 2 abuts against the inner wall surface of the second channel 124 to ensure that the fan 2 is assembled in place.

[0037] In some embodiments, as Figure 4 and Figure 5 As shown, the base 1 includes a surrounding plate 13, an intermediate plate 14 and an air duct 15 connected in sequence from bottom to top. The surrounding plate 13 is located in the first accommodating cavity 11 and surrounds the molded first channel 123. The intermediate plate 14 is located above the first accommodating cavity 11 and forms at least part of the second channel 124. The air duct 15 surrounds the remaining part of the molded air duct channel 12, and an air outlet 121 is provided at the top of the air duct 15.

[0038] The design of the air duct 15 can effectively increase the height of the air outlet 121, thereby effectively reducing the probability of the water stored in the base 1 entering the fan 2 through the air outlet 121, and effectively ensuring the working reliability of the humidifier.

[0039] For example, the air guide duct 15 is formed around the third channel, and the shape and size of the cross-sectional outer contour of the third channel are substantially the same as the shape and minimum size of the cross-sectional outer contour of the second channel 124 .

[0040] In some embodiments, as Figure 3 As shown, the base 1 further includes a partition 16 , which is connected to the air duct 15 , and blocks part of the air outlet 121 .

[0041] By providing the partition 16 to seal at least a portion of the air outlet 121 , it is possible to effectively prevent the user's fingers from being inserted into the fan 2 through the air outlet 121 to increase the risk of injury to the user, and the humidifier is highly safe to use.

[0042] For example, the partition 16 is arranged in the air duct 15. Taking the air duct 15 as a square tube, the partition 16 can divide the internal channel of the air duct 15 into at least two sub-channels arranged along the transverse direction of the air duct 15 (in a direction perpendicular to the length direction of the air duct 15). The partition 16 can also be connected to the air duct 15 at only one end, and the other end is a free end separated from the inner wall surface of the air duct 15.

[0043] In some embodiments, the partition 16 includes a grille plate, that is, the partition 16 divides the air outlet 121 into a plurality of grille holes. Alternatively, the partition 16 includes a partition bar disposed in the air outlet 121, which divides the air outlet 121 into two sub-holes of the same size and shape.

[0044] The sizes of the grille holes and sub-holes formed by the above arrangement can both prevent the user's fingers from entering the air guide channel 12, thereby effectively ensuring the safety of the humidifier.

[0045] For example, the partition plate 16 , the air duct 15 , the middle plate 14 , and the enclosure plate 13 are integrally formed.

[0046] In some embodiments, as Figure 3 As shown, the air duct 15 includes a tube wall 151 and a tube cover 152. The lower end of the tube wall 151 is connected to the middle plate 14, and the upper end of the tube wall 151 is connected to the tube cover 152. A first notch 1211 is provided on the tube wall 151, and a second notch 1212 is provided on the tube cover 152. The first notch 1211 and the second notch 1212 together constitute the air outlet 121.

[0047] This setting not only ensures that the air outlet 121 is located at the top end of the air guide pipe 15 to ensure that it has a sufficiently high height, but also enables the top of the air guide channel 12 to have a certain degree of protection, thereby better preventing the external water from entering the fan 2 through the air outlet 121, thereby further ensuring the performance and service life of the humidifier.

[0048] For example, the partition 16 is a vertical plate, the upper end of the partition 16 is connected to the tube wall 151, and the lower end of the partition 16 is connected to the tube wall 151. The first notch 1211 is located on the side of the tube wall 151 away from the central axis of the base 1. This can effectively reduce the probability of stored water entering the fan 2 through the air outlet when the stored water splashes onto the air guide duct 15.

[0049] In some embodiments, as Figure 2-Figure 5 As shown, the base 1 also has a second accommodating chamber 17, which is located above the middle plate 14. The humidifier air outlet assembly also includes a water valve 9, an adapter 10 and a float plate 110 connected in sequence. The water valve 9, the adapter 10 and the float plate 110 are all located in the second accommodating chamber 17, and the adapter 10 is pivotally connected to the middle plate 14.

[0050] After the humidifier's water tank assembly is connected to the base 1, the water valve 9 contacts the plug on the water tank assembly, causing the plug to release its seal on the lower opening of the water storage chamber 32 in the water tank assembly, allowing the water stored in the water storage chamber 32 to enter the second accommodating chamber 17. As the water is injected into the second accommodating chamber 17, the float 110 is gradually submerged. As the amount of water stored in the second accommodating chamber 17 gradually increases, the float 110 moves upward under the action of buoyancy, thereby driving the water valve 9 downward. This contacts the pressure exerted by the water valve 9 on the plug on the water tank assembly, and the plug is reset under the action of the spring to seal the lower opening of the water storage chamber 32. This ensures that the water level in the second accommodating chamber 17 remains below a set value, effectively preventing the water from filling the second accommodating chamber 17 and blocking the air guide channel 12 or entering the fan 2, thereby affecting the service life of the fan 2.

[0051] For example, the gravity of the float is greater than the gravity of the water valve 9 . When there is no water in the second accommodating chamber 17 , the float sinks and rests on the middle plate 14 . At this time, the water valve 9 is suspended relative to the middle plate 14 and higher than the float 110 .

[0052] The humidifier according to the embodiment of the present invention includes a water tank assembly and a humidifier air outlet assembly as in any of the above embodiments, and the water tank assembly is connected to the base 1 .

[0053] The technical advantages of the humidifier according to the embodiment of the present invention are the same as the technical advantages of the humidifier air outlet assembly in the above embodiment, and will not be repeated here.

[0054] In some embodiments, as Figure 1 and Figure 2 As shown, the water tank assembly includes a water tank 3, a first mist outlet cover 4, and a second mist outlet cover 5. The water tank 3 is provided with a mist outlet channel 31. The first mist outlet cover 4 is pivotally connected to the upper end of the water tank 3. The first mist outlet cover 4 and the water tank 3 are surrounded by a first mist outlet channel 31 that is connected to the mist outlet channel 31. The first mist outlet cover 4 is provided with a first mist outlet port 41 that is connected to the first mist outlet channel 31. The second mist outlet cover 5 is connected to the upper end of the water tank 3. The second mist outlet cover 5, the first mist outlet cover 4, and the water tank 3 are surrounded by a second mist outlet channel 31. The second mist outlet cover 5 is provided with a second mist outlet port 51 that is connected to the second mist outlet channel 31.

[0055] That is, the humidifier can emit mist through the first mist outlet 41 and the second mist outlet 51 at the same time, and the relative positions of the first mist outlet 41 and the second mist outlet 51 can be changed by rotating the first mist outlet cover 4, thereby adjusting the mist outlet range and effectively improving the humidification efficiency of the humidifier.

[0056] For example, the outer contours of the second mist outlet cover 5 and the water tank 3 are generally cylindrical, the second mist outlet cover 5 is coaxial with the water tank 3, the second mist outlet cover 5 is snap-connected to the water tank 3, the first mist outlet cover 4 is coaxial with the second mist outlet cover 5, and the first mist outlet cover 4 is pivotally connected to the water tank 3 around the central axis of the second mist outlet cover 5.

[0057] In some embodiments, as Figure 2 As shown, a water storage chamber 32 is provided in the water tank 3 , and a water inlet 33 communicating with the water storage chamber 32 is provided at the upper end of the water tank 3 .

[0058] That is, water can be added to the water storage chamber 32 through the water inlet 33, without the need to invert the water tank 3 and add water to the water storage chamber 32 through the lower opening of the water tank 3, thereby effectively reducing the difficulty of water filling and improving user satisfaction with water filling.

[0059] For example, the center of the top wall of the water tank 3 is concave, and there are multiple water inlets 33 located on the outer peripheral side of the second mist outlet cover 5 . The multiple water inlets 33 are evenly spaced along the circumference of the water tank 3 .

[0060] In some embodiments, the humidifier further includes a control module, which is installed on the base 1 . The control module includes a light button 6 , a timing button 7 and a plurality of timing indicator lights 8 .

[0061] By pressing the light button 6, the timing indicator light 8 and / or the power light on the humidifier can be turned on with one click. By pressing the timing button 7, multiple timing durations can be selected. The more timing indicator lights 8 are lit, the longer the timing duration.
