[0064] The humidifier 100 according to an embodiment of the present application is described below with reference to Figures 1-16.

[0065] Referring to Figures 1, 2 and 3, the humidifier 100 according to an embodiment of this application includes: a housing 1, a liquid-holding chamber 14 and a mist-guiding channel 15 disposed inside the housing 1, and a mist outlet 111 disposed at the upper end of the mist-guiding channel 15.

[0066] In this embodiment, the mist guiding channel 15 is adapted to cooperate with the atomizing element 2, the atomizing element 2 is adapted to generate water mist in the mist guiding channel 15, the mist guiding channel 15 guides the water mist to be discharged through the mist outlet 111, and the liquid holding chamber 14 is at least used to store the water falling in the mist guiding channel 15.

[0067] It should be noted that the atomizing element 2 can be integrated into the humidifier 100 itself, or it can be integrated into other components, as long as it can generate water mist within the mist guiding channel 15. For example, in some applications, the humidifier 100 is installed in a vehicle, which has an atomizing element 2, and the humidifier 100 works in conjunction with the atomizing element 2 to guide the water mist out. In other applications, the humidifier 100 is installed in an air conditioner, which has an atomizing element 2, and the humidifier 100 works in conjunction with the atomizing element 2 to guide the water mist out. In other applications, the humidifier 100 can also be applied to other structures, as long as the mist guiding channel 15 can cooperate with the atomizing element 2. It should be understood that the humidifier 100 can also be a standalone device. In some embodiments, the humidifier 100 further includes the atomizing element 2, which is installed in the housing 1 and is adapted to atomize the water in the liquid-containing chamber 14 into water mist through the mist guiding channel 15.

[0068] To prevent water falling directly onto the liquid surface of the liquid-collecting chamber 14 from generating noise in the mist-guiding channel 15, the humidifier 100 in this embodiment of the application further includes a noise-reducing component 3. The noise-reducing component 3 is located below the mist-guiding channel 15, and a portion of the noise-reducing component 3 is directly opposite the mist-guiding channel 15 to collect water droplets. The noise-reducing component 3 is provided with a first guide portion 311 extending toward the liquid-collecting chamber 14 to guide the liquid flow.

[0069] It should be noted that "directly opposite" in "part of the silencing component 3 is directly opposite to the mist guiding channel 15" means that part of the silencing component 3 can catch the water falling from the mist guiding channel 15 and prevent the water from dripping directly onto the liquid surface, which is the "directly opposite" that this patent claims to protect.

[0070] According to the embodiments of this application, the humidifier 100 provides a silencing component 3 below the mist guiding channel 15, allowing water falling in the mist guiding channel 15 to drip onto the silencing component 3 instead of dripping directly onto the liquid surface. This effectively reduces the noise generated during the operation of the humidifier 100. In addition, the silencing component 3 is provided with a first guide portion 311 extending toward the liquid holding chamber 14. Water falling on the silencing component 3 can flow toward the liquid holding chamber 14 under the guidance of the first guide portion 311, allowing the falling water to be reused. This reduces the frequency of water addition to the humidifier 100 and improves the practicality of the humidifier 100. Furthermore, water falling on the silencing component 3 can flow to the liquid holding chamber 14 through the first guide portion 311 instead of dripping directly from the silencing component 3 onto the liquid surface of the liquid holding chamber 14, avoiding noise generated by secondary dripping of water droplets and further improving the silencing effect of the silencing component 3.

[0071] Referring to Figures 4, 5 and 6, in some embodiments, the first guide portion 311 is formed as a first guide surface extending at a downward angle.

[0072] The above technical solution allows water droplets falling on the silencing component 3 to flow downwards along the first guide surface. Compared to water droplets falling directly, this reduces the speed of the droplets, thereby reducing the noise when the droplets enter the liquid surface of the liquid chamber 14. Furthermore, the structure of the first guide surface in this embodiment is simple, reducing the cost of the silencing component 3.

[0073] It should be noted that the first guiding surface can be an inclined plane or an arc-shaped surface, as long as it can guide the water to flow downwards.

[0074] In some embodiments, the first guide surface is positioned opposite the mist channel 15 to receive water droplets.

[0075] In this embodiment, water droplets are directly collected through the first guide surface, allowing water falling on the silencing component 3 to flow directly downwards along the inclined first guide surface. This avoids water accumulation on the silencing component 3, reduces the risk of bacterial growth inside the humidifier 100, and improves the safety of using the humidifier 100.

[0076] Referring to Figures 4, 5, and 6, in some embodiments, the humidifier 100 includes an atomizing element 2 disposed in the liquid-containing chamber 14. The silencing assembly 3 has a connecting channel 312 for connecting the mist-guiding channel 15 and the liquid-containing chamber 14. The top wall of the connecting channel 312 is positioned opposite to the mist-guiding channel 15 to collect water droplets. Preferably, the atomizing element 2 is an ultrasonic atomizing plate.

[0077] When the humidifier is working, the atomizing element 2 is adapted to transfer energy to the liquid in the liquid chamber 14. A water column is agitated in the center of the atomizing element 2 and rushes out of the liquid surface. The water column enters the mist guiding channel 15 through the connecting channel 312. After the water column rises to a certain height, the water clusters are broken due to the bursting of bubbles inside the water column. A small part of the water clusters are relatively small and form water mist, while the other water clusters fall directly to the silencer component 3.

[0078] In this embodiment, the silencing component 3 is provided with a connecting channel 312 to avoid the water column, so that the atomizing component 2 can directly stimulate the water column to the mist guiding channel 15, which simplifies the overall structure of the humidifier 100 and reduces the cost of the humidifier 100. In addition, the top wall of the connecting channel 312 is also used to collect water droplets, preventing water droplets from falling directly onto the liquid surface of the liquid holding chamber 14, which effectively improves the noise during the operation of the humidifier 100.

[0079] In some embodiments, at least a portion of the annular inner wall of the communication channel 312 forms a first guide portion 311 extending obliquely downward.

[0080] In this embodiment, a first guide portion 311 is formed by the inner wall of the connecting channel 312, which further simplifies the structure of the muffler component 3 and reduces the cost of the muffler component 3. Furthermore, the inner wall of the connecting channel 312 is annular, so that water droplets scattered around the water column can be collected by the first guide portion 311, which further improves the muffler's noise reduction effect.

[0081] In some embodiments, the noise reduction assembly 3 includes a main body 31, which is formed as an annular structure to define a communication channel 312. The cross-sectional area of ​​the communication channel 312 gradually decreases in the downward direction, such that the inner wall of the communication channel 312 is formed as a first guide surface.

[0082] In this embodiment, when the humidifier 100 is running, the water falling from the mist guiding channel 15 lands on the top wall of the connecting channel 312, and then flows towards the bottom of the connecting channel 312 through the inner wall of the connecting channel 312. This limits the flow pattern of water droplets on the main body 31, avoiding the possibility of secondary dripping of water from the main body 31, and effectively reducing the noise generated during the operation of the humidifier 100. Furthermore, in this embodiment, the main body 31 serves not only to connect the liquid-collecting chamber 14 and the mist guiding channel 15, but also to collect water droplets and guide their flow, effectively simplifying the structure of the noise-reducing component 3, facilitating its manufacture, and reducing the cost of the humidifier 100.

[0083] In some further embodiments, the angle between the plane containing the top of the first guide surface of the main body 31 or the tangent at the top and the horizontal plane is A1, 0°<A1≤60°.

[0084] With the above technical solution, A1 does not exceed 60°, so that the tilt of the top of the main body 31 relative to the horizontal plane is not too large, avoiding the water falling on the main body 31 from flowing downward too fast, thereby reducing the noise generated when the water comes into contact with the liquid surface.

[0085] In some further embodiments, the angle between the plane containing the bottom of the first guide surface of the main body 31 or the tangent at the bottom and the vertical plane is A2, 0°<A2≤30°.

[0086] With the above technical solution, A2 is greater than 0°, which avoids the bottom of the main body 31 being set vertically. Since water droplets may have a horizontal component velocity, avoiding the bottom of the main body 31 being set vertically can reduce the risk of water droplets detaching from the main body 31 and improve the guiding effect of the main body 31. In addition, A2 does not exceed 30°, so that the bottom of the main body 31 is not too flat, which is conducive to reducing the overall size of the silencing component 3.

[0087] In some embodiments, the humidifier 100 includes an atomizing element 2 disposed in a liquid-containing chamber 14, and a noise-reducing assembly 3 having a connecting channel 312 for connecting a mist-guiding channel 15 and a liquid-containing chamber 14. The top wall of the connecting channel 312 is disposed opposite to the mist-guiding channel 15 to collect water droplets.

[0088] In the vertical projection plane, the inner region of the connecting channel 312 in the projection of the noise-reducing component 3 is located within the projection plane of the atomizing component 2.

[0089] For example, the diameter of the bottom opening of the connecting channel 312 is smaller than the diameter of the atomizing element 2.

[0090] The above technical solution limits the diameter of the bottom opening of the connecting channel 312, thus preventing the bottom opening of the connecting channel 312 from being too large, which could cause some water in the mist guiding channel 15 to fall onto the liquid surface of the liquid holding chamber 14 through the bottom opening of the connecting channel 312.

[0091] In some further embodiments, the diameter of the bottom opening of the connecting channel 312 is R, where 5mm ≤ R ≤ 15mm.

[0092] If the diameter of the bottom opening of the connecting channel 312 is less than 5mm, the water column will have difficulty passing through, affecting the water mist entering the mist guiding channel 15; if the diameter of the bottom opening of the connecting channel 312 is greater than 15mm, some water in the mist guiding channel 15 will fall through the bottom opening of the connecting channel 312 to the liquid surface of the liquid holding chamber 14, generating noise.

[0093] In some embodiments, the diameter of the bottom opening of the communication channel 312 is 12 mm. In other embodiments, the diameter of the bottom opening of the communication channel 312 may also be 7 mm, 8 mm, 10 mm, or other sizes.

[0094] Referring to Figures 4, 5 and 6, in some embodiments, the bottom end of the main body 31 includes downwardly extending drainage teeth 32.

[0095] Through the above technical solution, the water at the bottom of the main body 31 can continue to flow downward along the drainage teeth 32, further reducing the distance between the water flowing down the silencing component 3 and the liquid surface of the liquid-containing cavity 14, further reducing the noise generated when the water flowing down the silencing component 3 comes into contact with the liquid surface of the liquid-containing cavity 14, and improving the silencing effect of the silencing component 3.

[0096] In some further embodiments, the humidifier 100 is configured such that the bottom end of the drainage tooth 32 is inserted into the liquid surface of the liquid-holding chamber 14, so that water can flow directly into the liquid surface of the liquid-holding chamber 14 through the drainage tooth 32, avoiding the noise generated by water dripping from the drainage tooth 32 to the liquid surface of the liquid-holding chamber 14, further improving the noise reduction effect of the silencing component 3, and effectively improving the noise problem during the operation of the humidifier 100.

[0097] In other embodiments, the humidifier 100 is configured such that the minimum distance between the bottom end of the drainage tooth 32 and the liquid surface of the liquid chamber 14 is L1, where L1 ≤ 15 mm.

[0098] When the humidifier 100 is running, the water falling in the mist guiding channel 15 lands on the top wall of the connecting channel 312, and then flows through the inner wall of the connecting channel 312 towards the bottom of the connecting channel 312. The water flowing out of the connecting channel 312 can continue to flow downward along the guide tooth 32, and finally drip from the bottom end of the guide tooth 32 to the liquid surface of the liquid holding chamber 14. In this embodiment, the minimum distance between the bottom end of the guide tooth 32 and the liquid surface of the liquid holding chamber 14 is limited, thereby reducing the noise when water drips onto the liquid surface of the liquid holding chamber 14.

[0099] In some specific embodiments, the minimum distance L1 between the bottom end of the drainage tooth 32 and the liquid surface of the liquid-containing cavity 14 is 15mm, 12mm, 8mm, 4mm or other dimensions.

[0100] It should be noted that the humidifier 100 is configured such that the liquid level in the liquid-holding chamber 14 is maintained at a set height. For example, in some embodiments, referring to FIG2, the housing 1 is provided with a liquid storage chamber 18, which is selectively connected to the liquid-holding chamber 14 via a connecting component 5 for replenishing liquid into the liquid-holding chamber 14. An atomizing element 2 is provided in the liquid-holding chamber 14 for atomizing the liquid in the liquid-holding chamber. A noise-reducing component 3 is located above the atomizing element 2. The mist in the liquid-holding chamber 14 can enter the mist guiding channel 15 through the connecting channel 312.

[0101] The atomizing element 2 is an ultrasonic atomizing plate. The atomizing element 2 can generate water mist through ultrasonic vibration, and water droplets will splash upwards at the same time. The noise reduction component 3 is located above the atomizing element 2, so that the noise reduction component 3 can guide these splashed water droplets and prevent them from hitting the liquid surface directly, further reducing the noise of the humidifier 100 during operation.

[0102] The humidifier 100 is configured such that when the liquid level in the liquid chamber 14 is lower than a set height, the connecting component 5 connects the liquid storage chamber 18 and the liquid holding chamber 14, so that the water in the liquid storage chamber 18 is replenished to the liquid holding chamber 14. When the liquid level in the liquid holding chamber 14 reaches the set height, the connecting component disconnects the liquid storage chamber 18 and the liquid holding chamber 14, so that the liquid level in the liquid holding chamber 14 can be maintained at the set height.

[0103] Through the above technical solution, the drainage tooth 32 can be kept in the state of being inserted into the liquid surface of the liquid-filled cavity 14 or the distance between the bottom end of the drainage tooth 32 and the liquid surface can be kept constant, thereby ensuring the reliability of the silencing component 3 during use.

[0104] Referring to Figures 13 and 14, in some specific embodiments, the housing is provided with an inlet 142 suitable for connecting the liquid storage chamber 18 and the liquid holding chamber 14. The connecting component 5 includes a float 51 and a sealing member 52. The float 51 is disposed in the liquid holding chamber 14 and fluctuates with the liquid level in the liquid storage chamber 18. The float 51 and the sealing member 52 are in a transmission cooperation. When the liquid level in the liquid storage chamber 18 drops, the float 51 drops and drives the sealing member 52 to avoid the inlet 142, so that the water in the liquid storage chamber 18 can be replenished into the liquid holding chamber 14 through the inlet 142. When the liquid level in the liquid storage chamber 18 rises to a set height, the float 51 rises with the liquid level and drives the sealing member 52 to close the inlet 142.

[0105] In other embodiments, a first sensor may be provided in the liquid-containing cavity 14. The first sensor is adapted to detect the water level or water pressure in the liquid-containing cavity 14. The communication component includes a solenoid valve adapted to connect the liquid storage cavity 18 and the liquid-containing cavity 14. The solenoid valve is configured to determine whether to connect the liquid storage cavity 18 and the liquid-containing cavity 14 based on the detection result of the first sensor.

[0106] It should be noted that the connecting component can also be other structures, as long as it can maintain the liquid level in the liquid-filling cavity 14 at a set height. This application does not impose any restrictions on this.

[0107] Referring to Figures 4, 5 and 6, in some embodiments, a plurality of drainage teeth 32 are provided, and the plurality of drainage teeth 32 are spaced apart along the circumferential direction of the main body 31.

[0108] Because water flows downward around the bottom opening of the main body 31, this embodiment provides multiple drainage teeth 32 around the bottom of the main body 31, so that the water passing through the main body 31 can flow downward under the guidance of the drainage teeth 32, reducing the risk of water dripping directly onto the liquid surface of the liquid chamber 14 after flowing out from the bottom of the main body 31, and improving the reliability of the silencing component 3.

[0109] In some embodiments, a first gap 321 is formed between two adjacent drainage teeth 32, and a diversion part 313 is provided for each first gap 321 in the main body 31. The diversion part 313 is used to divert a portion of water on the main body 31 to the drainage teeth 32 on both sides.

[0110] With the above technical solution, when the water in the main body 31 flows toward the first gap 321, it can be diverted to the drainage tooth 32 under the guidance of the diversion part 313, instead of dripping directly downward through the first gap 321. This further reduces the risk of water dripping directly onto the liquid surface of the liquid-holding cavity 14 after flowing out from the bottom of the main body 31, and improves the reliability of the silencing component 3.

[0111] In some embodiments, the diversion section 313 is formed as an arc-shaped opening facing downwards.

[0112] In this embodiment, the structure of the diversion section 313 is simple, which reduces the processing difficulty of the noise reduction component 3, thereby reducing the cost of the humidifier 100.

[0113] In other embodiments, the diversion section 313 may also be designed as a protruding structure that protrudes radially inward toward the connecting channel 312, and the protruding structure has inclined surfaces extending toward the guide teeth 32 on both sides. As long as the diversion section 313 can guide the water flowing toward the first gap 321 to the guide teeth 32, this application does not limit the specific construction of the diversion section 313.

[0114] Referring to Figures 4, 5 and 6, in some embodiments, the silencing component 3 further includes a water collection section 33, which defines a water receiving groove 331. The lower end of the first sidewall 1311 of the housing 1 that defines the mist guiding channel 15 is positioned opposite to the water receiving groove 331.

[0115] It should be noted that the "directly opposite" in "the lower end of the first side wall 1311 is directly opposite to the water receiving tank 331" means that the water receiving tank 331 can catch the water that slides down from the lower end of the first side wall 1311, preventing the water from dripping directly onto the liquid surface, which is the "directly opposite" that this patent claims to protect.

[0116] When the water column bursts open in the mist guiding channel 15, part of it falls directly to the main body 31 of the silencing component 3, while another part splashes onto the first side wall 1311 of the mist guiding channel 15 and flows downward along the first side wall 1311. In this embodiment, by setting a water receiving trough 331 at the lower end of the first side wall 1311, the water flowing on the first side wall 1311 can be collected into the water receiving trough 331 instead of dripping directly onto the liquid surface of the liquid holding chamber 14. This further avoids the noise when water droplets fall onto the liquid surface, improves the silencing effect of the silencing component 3, and improves the noise problem when the humidifier 100 is running.

[0117] In some further embodiments, the lower end of the first sidewall 1311 is located within the water receiving tank 331.

[0118] Through the above technical solution, water on the first sidewall 1311 can flow directly into the water receiving tank 331 instead of dripping into it, thereby improving the noise generated when water drips from the first sidewall 1311. Preferably, the lower end of the first sidewall 1311 abuts against the inner wall of the water receiving tank 331, thereby avoiding the noise generated when water drips from the first sidewall 1311 and further improving the noise reduction effect of the noise reduction component 3.

[0119] Referring to Figures 2 and 3, in some embodiments, the housing 1 includes: an outer shell 11, a first base plate 12, and a tube assembly 13. The top of the outer shell 11 is provided with a mist outlet 111. The first base plate 12 and the tube assembly 13 are both disposed within the outer shell 11. The tube assembly 13 includes a liquid-holding portion 132 and a tube portion 131. The bottom of the liquid-holding portion 132 is open. The first base plate 12 is disposed at the bottom end of the liquid-holding portion 132, and the first base plate 12 and the liquid-holding portion 132 define the aforementioned liquid-holding cavity 14. The tube portion 131 is located above the liquid-holding portion 132 and defines the aforementioned mist-guiding channel 15. The top of the mist-guiding channel 15 communicates with the mist outlet 111. The bottom end of the mist-guiding channel 15 is adapted to communicate with the liquid-holding cavity 14. A noise-reducing assembly 3 is disposed within the liquid-holding cavity 14 and located below the mist-guiding channel 15.

[0120] The aforementioned liquid storage chamber 18 is defined between the pipe assembly 13 and the outer shell 11, and a water inlet 142 is provided on the liquid holding part 132. Water in the liquid storage chamber 18 can be replenished to the liquid holding chamber 14 through the water inlet 142.

[0121] The atomizing element 2 is disposed on the first base plate 12. The atomizing element 2 is adapted to agitate the water in the liquid-containing cavity 14 upward into a water column. The water column enters the mist-guiding channel 15 through the connecting channel 312 of the silencing component 3. The water column explodes into water mist and water droplets in the mist-guiding channel 15. The water mist is adapted to be discharged through the mist outlet 111 at the upper end of the mist-guiding channel 15, while the water droplets fall to the silencing component 3 and then flow to the liquid surface of the liquid-containing cavity 14 under the guidance of the silencing component 3.

[0122] In this embodiment, the multiple cavities within the housing 1 are defined by structures such as the outer shell 11, the first base plate 12, and the tube assembly, which reduces the processing difficulty of the housing 1 and lowers the cost of the humidifier 100.

[0123] In some further embodiments, the tube assembly 13 is detachably connected to the housing 11, and the silencing assembly 3 and / or the communication assembly are detachably disposed on the tube assembly 13.

[0124] Through the above technical solution, the tube assembly 13 can be removed from the outer casing 11 for cleaning, reducing the risk of bacteria growth inside the humidifier 100; in addition, in this embodiment, the silencing assembly 3 and / or the connecting assembly are detachably disposed on the tube assembly 13, so that the silencing assembly 3 and / or the connecting assembly can also be removed from the tube assembly 13 for cleaning, further improving the convenience of cleaning the humidifier 100.

[0125] It should be noted that the detachable connection mentioned in the above technical solution can be a screw connection, a snap connection, a plug connection or other detachable connection, and this application does not limit it.

[0126] Referring to Figures 4, 5 and 6, in some specific embodiments, the bottom end of the first sidewall 1311 of the tube body 131 that defines the mist guiding channel 15 protrudes into the liquid holding cavity 14, so that the bottom end of the first sidewall 1311 can be located in the water receiving tank 331.

[0127] In this embodiment, the first sidewall 1311 and the water receiving tank 331 are matched in a simple way, which facilitates the assembly of the silencing component 3 and the pipe component 13 and improves the assembly efficiency of the humidifier 100.

[0128] Referring to Figures 4, 5 and 6, in some specific embodiments, the water collection part 33 is formed as an annular structure surrounding the main body part 31, so that the water receiving groove 331 is formed as an annular groove, and the bottom end of the first side wall 1311 can be located in the water receiving groove 331.

[0129] Through the above technical solution, all water on the first sidewall 1311 can enter the water receiving tank 331, further improving the noise generated by water droplets falling on the liquid surface and enhancing the reliability of the silencing component 3. In addition, the water receiving tank 331 can also catch water splashed from the main body 31, avoiding the risk of noise generated by water splashed from the main body 31 falling directly onto the liquid surface.

[0130] Referring to Figures 4, 5, and 6, in some specific embodiments, the water collection part 33 includes: a first vertical part 332, a first horizontal part 333, and a second vertical part 334. The top of the first vertical part 332 is connected to the outer periphery of the top of the main body part 31, the bottom of the first vertical part 332 is connected to the first horizontal part 333, and the side of the first horizontal part 333 away from the first vertical part 332 is connected to the bottom end of the second vertical part 334. The water receiving groove 331 is defined between the first vertical part 332, the first horizontal part 333, and the second vertical part 334.

[0131] In this embodiment, the water collection part 33 has a simple structure, which reduces the cost of the noise reduction component 3.

[0132] Referring to Figures 4, 5 and 7, in some embodiments, the water receiving tank 331 is provided with a water outlet 335.

[0133] Through the above technical solution, water in the water receiving tank 331 can flow out through the water outlet 335, avoiding long-term accumulation of water in the water receiving tank 331, reducing the risk of bacterial growth in the water receiving tank 331, and improving the safety of using the humidifier 100. Moreover, the water in the water receiving tank 331 can flow out through the water outlet 335, allowing the water receiving tank 331 to continuously receive water from the first side wall 1311, ensuring the reliability of the noise reduction component 3.

[0134] In some specific embodiments, the second vertical part 334 is provided with a water outlet 335 that communicates with the water receiving tank 331. Water in the water receiving tank 331 can be discharged directly through the water outlet 335. By setting the water outlet 335 in the second vertical part 334, it is also convenient for the user to clean the water collection part 33.

[0135] In some specific embodiments, the water receiving tank 331 is provided with a plurality of water outlets 335, which are distributed at intervals along the circumference of the water receiving tank 331.

[0136] By setting multiple water outlets 335 at intervals, water from different locations in the water receiving tank 331 can be discharged in a timely manner through the adjacent water outlets 335, further reducing the possibility of water accumulation in the water receiving tank, reducing the risk of bacteria growth in the water receiving tank 331, and improving the safety of using the humidifier 100.

[0137] In some embodiments, the silencing assembly 3 further includes a downwardly extending second guide portion 341, which is disposed opposite to at least a portion of the outlet 335 to guide the liquid to flow downward.

[0138] It should be noted that the "aligned" in "at least part of the second guide part 341 is aligned with the outlet 335" means that the second guide part 341 can receive the water flowing out of the outlet 335 and prevent the water flowing out of the outlet 335 from dripping directly onto the liquid surface, which is the "aligned" that this patent claims to protect.

[0139] Through the above technical solution, the water in the water receiving tank 331 can flow downward under the guidance of the second guide part 341 after flowing out through the water outlet 335, instead of dripping directly onto the liquid surface of the liquid holding chamber 14, which further improves the noise during the operation of the humidifier 100 and improves the reliability of the silencing component 3.

[0140] In some further embodiments, the second guide portion 341 extends to the liquid surface inserted in the liquid-holding cavity 14, so that water can flow directly into the liquid surface of the liquid-holding cavity 14 through the second guide portion 341, avoiding the noise generated by water dripping from the second guide portion 341 to the liquid surface of the liquid-holding cavity 14, further improving the noise reduction effect of the silencing component 3, and effectively improving the noise problem during the operation of the humidifier 100.

[0141] In other embodiments, the humidifier 100 is configured such that the minimum distance between the bottom end of the second guide portion 341 and the liquid surface of the liquid chamber 14 is L2, where L2 ≤ 15 mm.

[0142] In this embodiment of the application, the minimum distance between the bottom end of the second guide part 341 and the liquid surface of the liquid-filling cavity 14 is defined, thereby reducing the noise when water droplets fall onto the liquid surface of the liquid-filling cavity 14.

[0143] In some specific embodiments, the minimum distance L2 between the bottom end of the second guide part 341 and the liquid surface of the liquid-containing cavity 14 is 15mm, 12mm, 8mm, 4mm or other dimensions.

[0144] In some embodiments, the second guide portion 341 includes a first guide groove disposed on the outer peripheral wall of the muffler assembly 3. The first guide groove can guide the water flowing out of the outlet 335 to flow downward. The direction of the water flow is defined by the first guide groove, which reduces the possibility of water leaving the second guide portion and improves the guiding effect of the second guide portion. In addition, in this embodiment, the structure of the second guide portion is simple, which reduces the cost of the muffler assembly 3.

[0145] In some specific embodiments, multiple first guide grooves are provided, and multiple first guide grooves correspond one-to-one with multiple water outlets 335, so that the water discharged from each water outlet 335 can flow downward under the guidance of the corresponding first guide groove, thereby improving the reliability of the silencing component 3.

[0146] In some specific embodiments, the noise reduction component 3 further includes a first extension 34, which is disposed at the bottom of the second vertical part 334 and extends downward. The first extension 34 has a plate-like structure and is formed as part of the outer peripheral wall of the noise reduction component 3. A second guide part is disposed on the first extension 34.

[0147] In some embodiments, the second guide portion 341 includes a first guide groove disposed on the first extension portion 34. In other embodiments, the second guide portion 341 may also be an inclined surface or an arc-shaped surface disposed on the first extension portion 34, as long as it can guide water to flow downward. This application does not limit the specific structure of the second guide portion.

[0148] Referring to Figures 4, 7 and 8, in some embodiments, the noise reduction assembly 3 further includes a fixing part 35, through which the noise reduction assembly 3 is fixedly connected to the housing 1.

[0149] In this embodiment, the silencing component 3 is fixedly connected to the housing 1 through the fixing part 35, which improves the stability of the cooperation between the silencing component 3 and the housing 1, so that the silencing component 3 can stably collect the water falling into the mist guiding channel 15, thereby improving the reliability of the silencing component 3.

[0150] In some specific embodiments, the muffler assembly 3 is provided with multiple fixing parts 35. The muffler assembly 3 is fixed to the housing 1 through the multiple fixing parts 35, which effectively improves the stability of the connection between the muffler assembly 3 and the housing 1, further improves the stability of the cooperation between the muffler assembly 3 and the fog guiding channel 15, and improves the reliability of the muffler assembly 3.

[0151] In some specific embodiments, the fixing part 35 is at least connected to the top of the second vertical part 334, and the fixing part 35 is provided with a fixing hole 351; the housing 1 includes a tube assembly 13, and the top wall of the liquid-containing cavity 14 of the tube assembly 13 is provided with a fixing member 141, which is inserted into the fixing hole 351. The movement of the fixing part 35 is restricted by the friction between the fixing member 141 and the inner wall of the fixing hole 351, thereby fixing the silencing component 3 into the tube assembly 13.

[0152] It should be understood that in other embodiments, the fixing part 35 may also be fixed to the housing 1 by means of snap-fit, screw connection, adhesive bonding, etc. This application does not limit the specific connection method between the fixing part 35 and the housing 1.

[0153] In some embodiments, the silencing assembly 3 further includes a downwardly extending third guide portion 342, which is located below the fixing portion 35; the fixing portion 35 is provided with a fixing hole 351, and the housing 1 is provided with a fixing member 141 passing through the fixing hole 351; the third guide portion 342 is located on one side of the fixing member 141 to guide the liquid to flow downward.

[0154] In this embodiment, the water condensed on the fixing part 35 and the fixing member 141 can flow downward under the guidance of the third guiding part 342, instead of dripping directly onto the liquid surface of the liquid holding chamber 14, which further improves the noise during the operation of the humidifier 100 and improves the reliability of the silencing component 3.

[0155] In some further embodiments, the third guide portion 342 extends to the liquid surface inserted in the liquid-holding cavity 14, so that water can flow directly into the liquid surface of the liquid-holding cavity 14 through the third guide portion 342, avoiding the noise generated by water dripping from the third guide portion 342 to the liquid surface of the liquid-holding cavity 14, further improving the noise reduction effect of the silencing component 3, and effectively improving the noise problem during the operation of the humidifier 100.

[0156] In other embodiments, the humidifier 100 is configured such that the minimum distance between the bottom end of the third guide section 342 and the liquid surface of the liquid chamber 14 is L3, where L3 ≤ 15 mm.

[0157] In this embodiment of the application, the minimum distance between the bottom end of the third guide part 342 and the liquid surface of the liquid-containing cavity 14 is defined, thereby reducing the noise when water droplets fall onto the liquid surface of the liquid-containing cavity 14.

[0158] In some specific embodiments, the minimum distance L3 between the bottom end of the third guide part 342 and the liquid surface of the liquid-containing cavity 14 is 15mm, 12mm, 8mm, 4mm or other dimensions.

[0159] In some embodiments, the third guide portion 342 includes a second guide groove, and a portion of the fixing member 141 is located in the second guide groove. In this embodiment, the third guide portion 342 has a simple structure, which reduces the processing difficulty of the noise reduction component 3 and reduces the cost of the humidifier 100.

[0160] In some specific embodiments, the first extension 34 extends to the bottom of the fixing part 35, and the third guide part 342 is disposed on the first extension 34. In the embodiments of this application, both the second guide part 341 and the third guide part 342 are disposed on the first extension 34, which simplifies the structure of the muffler assembly 3 and reduces the cost of the muffler assembly 3.

[0161] In some embodiments, the third guide portion 342 includes a second guide groove disposed on the first extension portion 34. In other embodiments, the third guide portion 342 may also be an inclined surface or an arc-shaped surface disposed on the first extension portion 34, as long as it can guide water to flow downward. This application does not limit the specific structure of the third guide portion 342.

[0162] Referring to Figures 3, 6 and 9, in some embodiments, the housing 1 further defines an air guide channel 16, the air outlet of which is connected to the liquid chamber 14, and the humidifier 100 is configured to drive the gas in the liquid chamber 14 and the mist guide channel 15 toward the mist outlet 111 through the gas in the air guide channel 16.

[0163] Through the above technical solution, the humidifier 100 can use the airflow in the air guide channel 16 to carry the water mist in the liquid chamber 14 and the mist guide channel 15 to the mist outlet 111 for discharge, which effectively improves the water mist discharge efficiency and helps to increase the mist output of the humidifier 100.

[0164] Referring to Figures 3, 6, and 9, in some specific embodiments, the humidifier 100 is further provided with a fan 4. The fan 4 is adapted to drive air into the air guide channel 16. Under the guidance of the air guide channel 16, the air enters the liquid-containing chamber 14, then enters the mist-guiding channel 15 through the connecting channel 312, and finally is discharged to the outside through the mist outlet 111. During the air flow, the air carries water mist from the liquid-containing chamber 14 and the mist-guiding channel 15 together and is discharged from the mist outlet 111, thereby increasing the mist output of the humidifier 100. In the embodiments of this application, the mist discharge method of the humidifier 100 is simple, reducing the cost of the humidifier 100.

[0165] In some embodiments, the mist guiding channel 15 and the air guiding channel 16 are located above the liquid-containing cavity 14, and the partition plate 17 between the mist guiding channel 15 and the air guiding channel 16 is provided with a first opening 171 that connects them to each other.

[0166] When the humidifier 100 is running, the atomizing element 2 agitates the water in the liquid-containing chamber 14 into a water column. The water column enters the mist-guiding channel 15 through the connecting channel 312, where water mist is generated. The fan 4 drives air into the air-guiding channel 16. A portion of the gas in the air-guiding channel 16 enters the mist-guiding channel 15 directly through the first opening 171. The remaining gas in the air-guiding channel 16 first enters the liquid-containing chamber 14, then enters the mist-guiding channel 15 through the connecting channel 312. Finally, the gas and water mist in the mist-guiding channel 15 are discharged together from the mist outlet 111.

[0167] In this embodiment, by setting the first opening 171, some of the gas in the air guide channel 16 can directly enter the mist guide channel 15 through the first opening 171, thereby reducing the load on the fan 4, thereby reducing the noise generated by the fan 4 during operation, and improving the noise during the operation of the humidifier 100.

[0168] In some specific embodiments, the tube body portion 131 of the tube body assembly 13 not only defines the mist guiding channel 15, but also defines the air guiding channel 16. The partition plate 17 is disposed inside the tube body portion 131 to divide the space inside the tube body portion 131 into the mist guiding channel 15 and the air guiding channel 16.

[0169] In this embodiment, the air duct 16 is formed in a simple way, which reduces the cost of the humidifier 100.

[0170] In some embodiments, the bottom end of the partition plate 17 is provided with a first opening 171, and the bottom wall of the first opening 171 is formed as a second guide surface 172 extending toward the inner wall of the tube body 131. The second guide surface 172 is configured to guide liquid to the inner wall of the tube body 131.

[0171] When the humidifier 100 is running, some of the water mist in the mist guiding channel 15 will enter the first opening 171 and condense into water droplets on the bottom wall of the first opening 171. In this embodiment, by setting the bottom wall of the first opening 171 as a second guiding surface 172 extending toward the inner wall of the tube body 131, the condensed water droplets will flow toward the inner wall of the tube body 131 under the guidance of the second guiding surface 172, and then flow downward along the inner wall of the tube body 131, instead of dripping directly onto the bottom wall of the first opening 171, which effectively reduces the noise of the humidifier 100 during operation.

[0172] Referring to Figures 4, 6 and 8, in some embodiments, the silencing assembly 3 further includes a second extension 36, at least a portion of which is disposed directly opposite the air outlet of the air guide channel 16, the second extension 36 defining or participating in defining a second gap 363 for communicating the air guide channel 16 and the liquid chamber 14.

[0173] When the humidifier 100 is running, a portion of the gas in the air guide channel 16 enters the mist guide channel 15 through the first opening 171, and another portion of the gas enters the liquid holding chamber 14 through the second gap 363, then enters the connecting channel 312 through multiple first gaps 321, and then enters the mist guide channel 15 through the connecting channel 312.

[0174] Some of the water mist in the mist guiding channel 15 enters the air guiding channel 16 through the first opening 171. If there is no second extension 36 directly opposite the air outlet of the air guiding channel 16, the water droplets condensed in the air guiding channel 16 will fall directly onto the liquid surface of the liquid holding chamber 14, generating noise. However, in this embodiment, by having the second extension 36 directly opposite the air outlet of the air guiding channel 16, the water droplets condensed in the air guiding channel 16 can fall onto the second extension 36 instead of falling directly onto the liquid surface of the liquid holding chamber 14, effectively reducing the noise generated during the operation of the humidifier 100.

[0175] In some specific embodiments, the second extension 36 is connected to the top of the main body 31, and the top surface of the second extension 36 is inclined toward the main body 31, so that water on the second extension 36 can flow toward the main body 31 and finally flow downward through the first guide surface, thus ensuring the reliability of the silencing component 3.

[0176] Referring to Figures 4, 6 and 8, in some embodiments, a portion of the second extension 36 is spaced apart from the inner wall of the tube assembly 13 to define a second gap 363 between the second extension 36 and the inner wall of the tube assembly 13.

[0177] In this embodiment, the second gap 363 is formed in a simple way, which reduces the cost of the humidifier 100.

[0178] Referring to Figure 10, in some specific embodiments, the distance between the second extension 36 and the inner wall of the air guide channel 16 is the width of the second gap 363, and the width of the second gap 363 ranges from 6 to 8 mm.

[0179] If the width of the second gap 363 is greater than 8mm, it will result in the second gap 363 being too large, increasing the risk that water droplets condensed in the air guide channel 16 will fall onto the liquid surface of the liquid chamber 14 through the second gap 363.

[0180] In some specific embodiments, the width of the second gap 363 is 7 mm. In other embodiments, the width of the second gap 363 can also be any one of 6 mm, 6.5 mm, 7.5 mm, or 8 mm, or a range between any two.

[0181] In some other embodiments, the width of the second gap 363 in the horizontal direction is less than 6 mm. This further reduces the risk of water droplets condensed in the air guide channel 16 falling onto the liquid surface of the liquid-containing cavity 14 through the second gap 363.

[0182] In some specific embodiments, the width of the air inlet channel is 5mm. In other embodiments, the width of the air inlet channel may be 5.5mm, 5mm, 4.5mm, 3mm or other dimensions.

[0183] Referring to Figures 11 and 12, in some further embodiments, the second extension 36 includes a first portion 361 and a second portion 362. The first portion 361 is disposed directly opposite to the air outlet end of the air guide channel 16. The second portion 362 is connected to the end of the first portion 361 and extends upward into the air guide channel 16. The second portion 362 and the inner wall of the air guide channel 16 are spaced apart to define a second gap 363.

[0184] This embodiment of the application provides an upwardly extending second portion 362, which can block water mist from entering the mist guiding channel 15 from the first opening 171, and prevent water mist from entering the second gap 363. This reduces the risk of water droplets falling onto the liquid surface of the liquid holding chamber 14 through the second gap 363, and effectively improves the noise during the operation of the humidifier 100.

[0185] In some specific embodiments, a second gap 363 is defined between the second portion 362 and the inner wall of the air guide channel 16, the distance between the second portion 362 and the inner wall of the air guide channel 16 is the width of the second gap 363, and the height of the second portion 362 is greater than or equal to the width of the second gap 363.

[0186] In this embodiment of the application, by limiting the height of the second part 362, the risk of water mist entering the second gap 363 is further reduced, and the risk of water droplets falling onto the liquid surface of the liquid-containing cavity 14 through the second gap 363 is further reduced.

[0187] Referring to Figures 4, 7 and 8, in some embodiments, the first extension 34 extends toward the second gap 363, and the first extension 34 is provided with a fourth guide surface 343. The fourth guide surface 343 is used to guide the water in the second gap 363 to flow downward, further reducing the risk of water droplets falling through the second gap 363 onto the liquid surface of the liquid-containing cavity 14.

[0188] In some embodiments, the second extension 36 blocks the air outlet of the air guide channel 16, and the second extension 36 is provided with a second gap 363 extending through it.

[0189] In some of the above embodiments, a second gap 363 is defined between the second extension 36 and the inner wall of the tube assembly 13. In this embodiment, the second extension 36 defines the second gap 363 independently, as long as the gas in the air guide channel 16 can enter the liquid-containing cavity 14. This application does not limit the specific formation method of the second gap 363. In some other embodiments, the second gap 363 may also be multiple.

[0190] In some further embodiments, the second extension 36 is also provided with an upwardly extending shielding portion, which is disposed between the second gap 363 and the first opening 171.

[0191] This allows the shielding part to block water mist from entering the mist guiding channel 15 from the first opening 171, preventing water mist from entering the second gap 363. This reduces the risk of water droplets falling onto the liquid surface of the liquid holding chamber 14 through the second gap 363, effectively improving the noise during the operation of the humidifier 100.

[0192] In some embodiments, the opening area of ​​the first opening 171 is S1, the cross-sectional area of ​​the air guide channel 16 is S2, the air passage area of ​​the first gap 321 is S3, the opening area of ​​the second gap 363 is S4, and the housing 1 is configured such that S2≥S1+S4.

[0193] It should be noted that the air passage area refers to the opening area of ​​the portion of the first gap 321 through which gas passes. In some embodiments, a portion of the drainage tooth is inserted into the liquid surface, that is, a portion of the first gap is located below the liquid surface. In such embodiments, the air passage area refers to the opening area of ​​the portion of the first gap located above the liquid surface.

[0194] It should also be noted that in embodiments with multiple first gaps 321, S3 refers to the sum of the air passage areas of the multiple first gaps 321. S2 refers to the minimum cross-sectional area of ​​the air guide channel 16.

[0195] When the humidifier 100 is working, the gas in the air guide channel 16 is divided into two parts. One part enters the mist guide channel 15 through the first opening 171, and the other part enters the liquid holding chamber 14 through the second gap 363.

[0196] When S2 = S1 + S4, the air resistance of the gas in the air guide channel 16 entering the mist guide channel 15 and the liquid holding chamber 14 can be reduced, ensuring the air volume in the mist guide channel 15, increasing the mist output of the humidifier 100, and also reducing the noise of the air duct.

[0197] When S2 > S1 + S4, the air pressure in the portion of the air guide channel 16 near the first opening 171 and near the second gap 363 increases, which helps to increase the flow velocity of the gas through the first opening 171 and the flow velocity of the gas through the second gap 363, thereby allowing the airflow to carry out more mist and increase the mist output of the humidifier.

[0198] In other embodiments, the opening area of ​​the first opening 171 is S1, the cross-sectional area of ​​the air guide channel 16 is S2, the air passage area of ​​the first gap 321 is S3, the opening area of ​​the second gap is S4, and the housing 1 is configured such that S4≥S3.

[0199] When the humidifier 100 is working, the airflow entering the liquid-containing chamber 14 from the second gap 363 carries the mist in the liquid-containing chamber 14 through the first gap 321.

[0200] When S4 = S3, the wind resistance of the gas passing through the first gap 321 can be reduced, the air volume in the mist guiding channel 15 can be guaranteed, the mist output of the humidifier 100 can be increased, and the noise of the air duct can also be reduced.

[0201] When S4 > S3, the air pressure in the part of the liquid-filled chamber 14 near the first gap 321 increases, which helps to increase the flow rate of gas through the first gap 321, thereby allowing the airflow to carry out more mist and increase the mist output of the humidifier.

[0202] In some other embodiments, the opening area of ​​the first opening 171 is S1, the cross-sectional area of ​​the air guide channel 16 is S2, the air passage area of ​​the first gap 321 is S3, the opening area of ​​the second gap is S4, and the housing 1 is configured such that S2≥S1+S4, while the housing 1 is configured such that S4≥S3.

[0203] The above technical solution further improves the mist output of the humidifier.

[0204] Referring to FIG5, in some embodiments, the surface of the silencing component 3 facing the liquid-filled cavity 14 is provided with a third guide surface 314, the third guide surface 314 extends downward at an angle toward the connecting channel 312, and at least a portion of the third guide surface 314 is disposed adjacent to the second gap 363.

[0205] Through the above technical solution, water droplets passing through the second gap 363 can flow downward along the third guide surface 314, preventing water droplets passing through the second gap 363 from dripping directly onto the liquid surface, further reducing the noise during the operation of the humidifier 100; in addition, the third guide surface 314 can also be used to guide the gas entering the liquid chamber 14 from the second gap 363, so that the gas can pass through the first gap 321, improving the smoothness of gas flow in the humidifier 100.

[0206] In some specific embodiments, the side of the main body 31 that is away from the first guide portion 311 is formed as a third guide surface 314, which further simplifies the structure of the muffler assembly 3 and reduces the cost of the muffler assembly 3.

[0207] Referring to Figure 4, in some embodiments, the portion of the first guide section 311 that is directly opposite the mist guiding channel 15 is the first region 3111, and the portion of the first guide section 311 that is directly opposite the air guiding channel 16 is the second region 3112. The area of ​​the first region 3111 is larger than the area of ​​the second region 3112.

[0208] When the humidifier 100 is working, the atomizing element 2 is adapted to transfer energy to the liquid in the liquid-holding chamber 14. A water column is agitated in the center of the atomizing element 2, which then flows out of the liquid surface. The water column enters the mist-guiding channel 15 through the connecting channel 312. After the water column rises to a certain height, the water droplets burst due to the rupture of bubbles inside the water column. A small portion of the water droplets are relatively small and form water mist, while the rest fall directly to the silencing component 3. The water droplets in the air-guiding channel 16 are formed by the condensation of the mist diffused from the liquid-holding chamber 14 or the mist-guiding channel 15 into the air-guiding channel 16. In other words, the number of water droplets falling in the mist-guiding channel 15 is far greater than the number of water droplets falling in the air-guiding channel 16. In this embodiment, the area of ​​the first region 3111 is larger than the area of ​​the second region 3112, allowing the first region 3111 to hold more water droplets, thus ensuring the reliability of the first guide part 311 in holding water droplets.

[0209] In some embodiments, the first guide portion 311 is not provided with a through hole.

[0210] With the above technical solution, no through hole is provided on the first guide part 311. That is to say, water falling on the first guide part 311 can flow stably to the connecting channel 312, and will not fall onto the liquid surface through the through hole on the first guide part 311, thus avoiding the noise of secondary dripping of water droplets. In addition, since no through hole is provided on the first guide part 311, the gas in the liquid chamber 14 cannot pass through the first guide part 311 to enter the mist guiding channel 15, but can only enter the mist guiding channel 15 through the connecting channel 312, which further limits the flow direction of the gas in the humidifier 100 and ensures the reliability of the mist output of the humidifier 100.

[0211] In some embodiments, the noise reduction component 3 is constructed as a single molded part.

[0212] The above technical solution effectively reduces the processing difficulty of the muffler component 3, reduces the connection process of each part in the muffler component 3, improves the overall strength of the muffler component 3, reduces the risk of damage to the muffler component 3, and extends the service life of the muffler component 3.

[0251] The sound-absorbing component 3 is a one-piece molded part.

[0252] In this embodiment, when the humidifier 100 is running, the atomizing element 2 is adapted to transfer energy to the liquid in the liquid-holding chamber 14, a water column is agitated in the center of the atomizing element 2 and flows out of the liquid surface. The water column enters the mist-guiding channel 15 through the connecting channel 312. After the water column rises to a certain height, the water droplets burst due to the rupture of bubbles inside the water column. A small portion of the water droplets are relatively small and form water mist, while the other water droplets fall directly to the silencer component 3.
