When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0055] The present disclosure provides a humidifier, and the humidifier includes an air outlet cavity and a first light guide part.

[0056] The air outlet cavity includes an air outlet grille and an air outlet top cover. The air outlet grille is arranged in a ring shape, and the annular surface of the air outlet grille allows air to flow through. The air outlet top cover is arranged to contract from one end to the other end, forming a funnel-shaped structure having a contraction end and an expansion end. The contraction end of the air outlet top cover is connected to the inner ring edge of the air outlet grille.

[0062] In some embodiments, the user injects water into the humidifier through the upper end of the air outlet cover 1, and the water flows into the water storage tank 8 through the water inlet pipe arranged in the outer shell 9, and is transported to the humidification tank 7 through the water supply pipe in the water storage tank 8.

[0063] In some embodiments, other substances, such as aromatic substances, disinfecting substances, etc., may also be added to the humidification tank 7 or the water storage tank 8. Users can choose to add or not add according to their own needs, and the present disclosure does not limit this.

[0064] In some embodiments, the humidifying chamber 7 includes an evaporation layer 71 that is circumferentially closed. The water in the upper water pipe is delivered to the evaporation layer 71 for humidifying the evaporation layer 71. An air inlet 91 communicating with the humidifying chamber 7 is formed on the outer shell 9. Air enters the humidifying chamber 7 from the air inlet 91, and the water in the evaporation layer 71 evaporates when passing through the evaporation layer 71, humidifying the air.

[0065] In some embodiments, the evaporation layer 71 is made of a fibrous material and has a certain water absorption capacity, which is beneficial to water evaporation. The evaporation layer 71 can be referred to as a wet curtain.

[0066] In some embodiments, a filter layer 72 is provided between the air inlet 91 and the evaporation layer 71 to filter the air before humidifying it, preventing harmful substances in the air from contaminating the evaporation layer 71. In some embodiments, the humidifier can be an air humidifying and purifying integrated machine with both humidifying and air purifying functions.

[0067] In some embodiments, the filter layer 72 can be arranged to surround the evaporation layer 71 in a circle to improve the filtering effect. However, the present disclosure is not limited to this. In some embodiments, the filter layer 72 can be of any shape.

[0068] In some embodiments, the filter layer 72 can be a HEPA filter element.

[0069] In some embodiments, the filter layer 72 may not be provided in the humidifying chamber 7, and those skilled in the art can decide whether to provide the filter layer 72 according to actual needs.

[0070] In some embodiments, the drive chamber 6 communicates with the humidifying chamber 7 and only communicates with the internal space of the evaporation layer 71, preventing unhumidified air from entering the drive chamber 6.

[0071] In some embodiments, the drive chamber 6 includes a drive motor 61 and an impeller 62 that is power-connected to the drive motor 61. The axial directions of both the drive motor 61 and the impeller 62 are arranged in the vertical direction. The drive motor 61 drives the impeller 62 to rotate, sucking the humidified air in the humidifying chamber 7 into the drive chamber 6 and passing through the drive chamber 6, and then outputting it to the outside of the humidifier through the air outlet 2.

[0072] In some embodiments, the humidifier further includes a control module for making the humidifier work in a preset manner to control the humidifier.

[0073] Figure 3 、 Figure 4 、 Figure 5 are partial structural schematic diagrams of a humidifier shown according to an exemplary embodiment, Figure 6 is Figure 5 the enlarged view of part A in Figure 3 、 Figure 4, Figure 5 as well as Figure 6 As shown, the humidifier includes an air outlet cavity and a first light guide 3. The air outlet cavity includes an air outlet grille 21 and an air outlet top cover 1. The air outlet grille 21 is arranged in a ring shape, and the annular surface of the air outlet grille 21 is for air to flow through. The air outlet top cover 1 is arranged to shrink from one end to the other end to form a funnel-shaped structure with a shrinking end and an expanding end. The shrinking end of the air outlet top cover 1 is connected to the inner ring edge of the air outlet grille 21. The expanding end of the air outlet top cover 1 and the outer ring edge of the air outlet grille 21 form an air outlet 2 arranged circumferentially along the air outlet grille 21.

[0074] The first light guide portion 3 includes a first light shielding plate 34, a first light source 31, a first light guide structural member 32 and a first light guide structural body 33. The first light shielding plate 34 is arranged on one side of the inner ring of the air outlet grille 21 and is arranged along the circumference of the inner ring of the air outlet grille 21. The first light source 31 is arranged between the first light shielding plate 34 and the air outlet grille 21, is arranged along the circumference of the inner ring of the air outlet grille 21, and is opposite to the first light shielding plate 34. The first light source 31 irradiates light toward the first light shielding plate 34. The first light guide structural member 32 is arranged between the first light shielding plate 34 and the first light source 31, is arranged along the circumference of the inner ring of the air outlet grille 21, and the first light guide structural member 32 extends radially toward the first light shielding plate 34 to form a light guide extension portion 321. The light guide extension portion 321 avoids the first light source 31 in the radial direction of the first light guide structural member 32. The first light guide structure body 33 is contracted from one end to the other end to form a funnel-shaped structure with a contracted end and an expanded end. The expanded end of the first light guide structure body 33 is connected to the expanded end of the air outlet top cover 1, and the contracted end of the first light guide structure body 33 abuts against the light guide extension portion 321 of the first light guide structural member 32.

[0075] In the embodiment of the present disclosure, the first light guide structure body 33 is arranged in the air outlet cavity, which can produce a luminous effect in the air outlet cavity, thereby improving the overall aesthetics of the humidifier, especially when the humidifier is working, the misty airflow flows into the air outlet cavity from the air outlet grille 21, covers the first light guide structure body 33, and the light emitted by the first light guide structure body 33 is mapped into the misty airflow, which will obtain a higher light effect. At the same time, the light guide extension part 321 used for guiding light to the first light guide structure body 33 is arranged to avoid the first light source 31, so that the light emitted by the first light source 31 cannot be directly projected into the first light guide structure body 33, thereby making the light emitted by the first light guide structure body 33 into the misty airflow softer, further improving the visual effect of the humidifier, and avoiding direct light causing discomfort to the user's eyes.

[0076] In some embodiments, the air outlet grille 21 is annular, which means that the middle of the air outlet grille is hollow and is used to install the air outlet top cover 1 or Figure 2 The inner ring profile and the outer ring profile of the drive chamber 6 in the embodiment of the present invention can be any shape. For example, the outer ring profile is square and the inner ring profile is circular.

[0077] In some embodiments, the first light-shielding plate 34, the first light source 31, and the first light-guiding structural member 32 in the first light-guiding portion 3 may be arranged as a complete ring, may be arranged as a part of a ring, such as a ring sector, or may be arranged as several spaced-apart parts. The first light-shielding plate 34, the first light source 31, and the first light-guiding structural member 32 may be arranged in the same or different ways.

[0078] In some embodiments, the air flow released by the humidifier may be white and foggy or colorless, and the present disclosure does not limit this.

[0079] In some embodiments, such as Figure 6 shown, the first light-guiding structural member 32 is provided with a light-blocking groove 322 along the edge of the light-guiding extension portion 321, and the first light-shielding plate 34 extends into the light-blocking groove 322.

[0080] In the embodiments of the present disclosure, extending the first light-shielding plate 34 into the light-blocking groove 322 can prevent light leakage at the part where the first light-shielding plate 34 is in contact with the main body 33 of the first light-guiding structure, so that all the light projected onto the air flow in the air outlet cavity is emitted from the main body 33 of the first light-guiding structure, making the light more uniform.

[0081] In some embodiments, such as Figure 5 , Figure 6 shown, a circular first accommodation groove 212 with a notch facing the air outlet top cover 1 is formed in the inner ring of the air outlet grille 21. A first light source 31, a first light-guiding structural member 32, and a first light-shielding plate 34 are sequentially arranged from the bottom of the first accommodation groove 212 to the notch. A circular sealing piece 22 for closing the notch is arranged at the notch of the first accommodation groove 212, and the first light-guiding structural member 32 and the main body 33 of the first light-guiding structure guide light with the sealing piece 22 therebetween.

[0082] In the embodiments of the present disclosure, arranging the first light source 31, the first light-guiding structural member 32, and the first light-shielding plate 34 in the first accommodation groove 212 and sealing the first accommodation groove 212 with the sealing piece 22 can effectively isolate the first light source 31 from the humid air flow in the air outlet cavity, avoid the moisture in the air flow from having an adverse effect on the first light source 31, improve the service life and stability of the first light source 31. At the same time, the sealing piece 22 is light-transmissive and will not affect the light transmission between the first light-guiding structural member 32 and the main body 33 of the first light-guiding structure.

[0083] In some embodiments, the sealing piece 22 may be a PET waterproof film (i.e., polyethylene terephthalate), which can withstand high temperatures and is insulating.

[0084] In some embodiments, such as Figure 3 , Figure 4As shown, the first light source 31 includes an annular circuit board and LED lamp beads arranged at intervals along the circuit board. The first light guide structure 32 is provided with a cavity for accommodating these LED lamp beads, so as to guide all the light emitted by the LED lamp beads into the first light guide structure 32, avoiding waste of the light source and also avoiding light leakage.

[0085] The LED lamp beads can also be replaced with other light-emitting components, such as incandescent lamps, etc., and the present disclosure does not limit this.

[0086] Figure 7 is Figure 5 the enlarged view at position B in Figure 5 、 Figure 6 As shown, the first light guide structure main body 33 includes a first fixing part 331. As Figure 5 、 Figure 7 shown, the first light guide structure main body 33 includes a plurality of second fixing parts 332.

[0087] As Figure 5 、 Figure 6 shown, the contraction end of the first light guide structure main body 33 extends radially inward to form an annular first fixing part 331. The first fixing part 331 is arranged between the inner ring edge of the air outlet grille 21 and the contraction end of the air outlet top cover 1, and the air outlet grille 21 and the air outlet top cover 1 clamp and fix the first fixing part 331.

[0088] As Figure 5 、 Figure 7 shown, the expansion end of the first light guide structure main body 33 protrudes towards the air outlet top cover 1 with a plurality of hollow cylinders to form second fixing parts 332. The second fixing parts 332 are inserted into the air outlet top cover 1 and fixed to the air outlet top cover 1 by bolts.

[0089] In the embodiment of the present disclosure, fixing the expansion end and the contraction end of the first light guide structure main body 33 at both ends of the air outlet top cover 1 respectively can prevent the interior of the air outlet top cover 1 from being invaded by humid air currents and rusting or breeding bacteria, effectively avoiding corrosion and mildew of the air outlet top cover 1. At the same time, the first light guide structure main body 33 is fixed by clamping, without the need to additionally add fixing parts, with a simple structure and convenient assembly.

[0090] In some embodiments, as Figure 5 、 Figure 7 shown, the expansion end of the air outlet top cover 1 is provided with a first sealing groove 111 facing the air outlet grille 21. A flexible sealing ring 113 is arranged in the first sealing groove 111, and the edge of the expansion end of the first light guide structure main body 33 is inserted into the first sealing groove 111 and abuts against the flexible sealing ring 113.

[0091] In the embodiment of the present disclosure, by adding a flexible sealing ring 113 in the first sealing groove 111 , the sealing effect between the air outlet top cover 1 and the first light guide structure body 33 can be enhanced, thereby preventing water from entering the air outlet top cover 1 to the greatest extent.

[0092] The flexible sealing ring 113 can be a rubber ring or a flexible ring made of other materials. The cross section of the flexible sealing ring 113 is preferably set to be circular. The flexible sealing ring 113 and the first sealing groove 111 are interference fit.

[0093] Figure 8 is a partial structural schematic diagram of a humidifier according to an exemplary embodiment. Figure 9 yes Figure 8 The enlarged view of point C in the middle. Figure 8 , Figure 9 As shown, the humidifier includes a display component 4 arranged on the air outlet top cover 1, and the display component 4 includes a second light guide part 5 and a screen assembly. The second light guide part 5 includes: a second light source 52, a second light shielding structure 53 and a second light guide structure 51. The second light source 52 is arranged around the screen assembly. The second light shielding structure 53 is arranged around the screen assembly, opposite to the second light source 52 and spaced apart. The second light guide structure 51 is arranged between the second light source 52 and the second light shielding structure 53. The second light guide structure is arranged around the screen assembly, and a light exit part 512 is extended in the radial direction of the second light source 52. The light exit part 512 avoids the second light source 52 in the radial direction of the second light guide structure 51.

[0094] In the embodiment of the present disclosure, by placing the light emitting portion 512 away from the second light source 52, the light emitted by the second light source 52 cannot directly reach the light emitting portion 512, but needs to be reflected and scattered in the second light guiding structure 51 before being emitted from the light emitting portion 512, so that the emitted light is softer and scattered more evenly, thereby avoiding discomfort to the user's eyes.

[0095] At the same time, the first light guide part 3 and the second light guide part 5 cooperate to emit light from the side and top of the humidifier. On the one hand, it can make the humidifier more beautiful, and on the other hand, it can also provide users with certain lighting functions to facilitate use of the humidifier at night.

[0096] In some embodiments, the second light source 52, the second light shielding structure 53 and the second light guiding structure 51 of the second light guiding portion 5 can be arranged in a complete ring, or in a part of a ring, such as a ring sector, or in a plurality of parts spaced apart along the circumferential direction. The second light source 52, the second light shielding structure 53 and the second light guiding structure 51 can be arranged in the same manner or in a different manner.

[0097] In some embodiments, Figure 8 , Figure 9As shown, the humidifier further includes a base 41 and a display cover plate 42 covering the base 41. A second light source 52, a second light guide structure 51, and a second light shielding structure 53 are sequentially arranged from the base 41 towards the display cover plate 42.

[0098] The light-emitting portion 512 of the second light guide structure 51 extends towards the display cover plate 42 and abuts against the display cover plate 42. The second light shielding structure 53 extends towards the display cover plate 42 and abuts against the display cover plate 42. The contact surface between the second light guide structure 51 and the second light shielding structure 53 is set to be arc-shaped.

[0099] In the present disclosure, setting the contact surface between the second light guide structure 51 and the second light shielding structure 53 to be arc-shaped is beneficial for the light of the second light source 52 to be transmitted to the portion abutting against the display cover plate 42, reducing the proportion of the light amount reflected to the light-emitting portion 512 in the second light guide structure 51 due to the irradiation direction of the second light source 52 being close to perpendicular to the edge of the second light guide structure 51, and more effectively utilizing the light of the second light source 52. At the same time, the light-emitting portion 512 is in direct contact with the display cover plate 42, and a clearer light-emitting contour can be displayed outside the display cover plate 42, avoiding the light-emitting edge from becoming blurred and improving the light-emitting display effect.

[0100] In some embodiments, the second light source 52 includes an annular circuit board and a plurality of LED lamp beads spaced on the circuit board. The second light guide structure 51 is provided with a receiving cavity for receiving the LED lamp beads, so as to introduce all the light emitted by the LED lamp beads into the second light guide structure 51 and efficiently utilize the light amount of the LED lamp beads.
