Technical Field

[0001] This invention relates to the field of humidifiers, and in particular to a mist output component and a humidifier. Background Technology

[0002] A humidifier is a household appliance that increases the humidity in a room. It works by atomizing water into a mist, which increases the humidity of the air in the room, freshens the air, and creates a comfortable environment.

[0003] In related technologies, humidifiers generate significant noise during operation, resulting in noise pollution. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following is for reference. Figures 1-14 The mist output assembly 100 of a humidifier according to an embodiment of the present invention is described.

[0045] It should be noted that, referring to Figure 14 The humidifier 1000 includes a mist-generating chamber 210 and an atomizing element 300. The atomizing element 300 is used to atomize the liquid in the mist-generating chamber 210. When the atomizing element 300 is working, the atomizing element 300 itself may generate noise, and the surging or boiling of the liquid in the mist-generating chamber 210 will also generate noise. In other words, when the humidifier 1000 is working, not only water mist will be generated in the mist-generating chamber 210, but also noise will be generated.

[0046] Reference Figure 1 , Figure 2 and Figure 3According to an embodiment of the present invention, the mist-generating assembly 100 of a humidifier includes: a main body portion 110, which defines a mist exhaust channel 111 adapted to communicate with a mist-generating chamber 210, and the mist exhaust channel 111 having a mist exhaust port 112. When the humidifier 1000 is operating, water mist is generated in the mist-generating chamber 210, and the water mist is discharged into the room from the mist exhaust port 112 under the guidance of the mist exhaust channel 111 to improve the indoor air. However, at the same time, noise in the mist-generating chamber 210 also propagates in the mist exhaust channel 111, and part of the noise propagates towards the mist exhaust port 112, while part of the noise penetrates the mist exhaust channel 111 and propagates outward.

[0047] In order to improve the noise situation in the mist exhaust channel 111, in this embodiment of the invention, the mist exhaust component 100 further includes a noise reduction part 120. The noise reduction part 120 is disposed in the main body part 110. The noise reduction part 120 defines or participates in defining a silencing cavity 121. The silencing cavity 121 is provided with a silencing hole 122 communicating with the mist exhaust channel 111.

[0048] When sound waves propagate within the desiccation channel 111, they diffuse towards the silencing hole 122 and the silencing cavity 121. The air column within the silencing hole 122 vibrates like a piston, while the air within the silencing cavity 121 is compressed or expanded, creating an elastic restoring force, similar to the action of a spring. In other words, the sound waves within the desiccation channel 111 resonate with the air within the silencing hole 122 and the silencing cavity 121. During resonance, the intense vibration of the air column within the silencing hole 122 causes the air molecules within the silencing hole 122 to rub against the inner wall of the silencing hole 122, converting sound energy into heat energy. The compression and expansion of the air inside the silencing cavity 121 also consumes energy due to the viscosity effect. The silencing cavity 121 and the silencing hole 122 can also reflect sound waves. The reflected sound waves superimpose with the original sound waves, achieving destructive interference, thereby improving the noise situation within the desiccation channel 111.

[0049] According to an embodiment of the present invention, the mist outlet assembly 100 of the humidifier has a noise reduction portion 120 provided on the main body 110, which connects the mist exhaust channel 111 with the silencer hole 122 and the silencer cavity 121. When the sound wave propagates in the mist exhaust channel 111, it resonates with the air in the silencer hole 122 and the silencer cavity 121, thereby reducing the energy of the sound wave and effectively improving the noise situation at the mist outlet 112. Furthermore, the noise reduction portion 120 also increases the thickness of the mist outlet assembly 100, making it more difficult for the sound wave to propagate outward through the mist outlet assembly 100, further reducing the noise passing through the mist outlet assembly 100, and effectively improving the noise problem when the humidifier 1000 is working.

[0050] In some embodiments, the silencing hole 122 is disposed at the bottom of the silencing cavity 121.

[0051] When the humidifier 1000 is working, the water mist is connected in the mist exhaust channel 111. Some of the water mist will enter the silencer cavity 121 through the silencer hole 122 and recondense into liquid water. In this embodiment of the invention, by setting the silencer hole 122 at the bottom of the silencer cavity 121, the water in the silencer cavity 121 can flow to the silencer hole 122 and be discharged through the silencer hole 122, which reduces the possibility of water accumulation in the silencer cavity 121, reduces the possibility of bacteria growing in the mist output component 100, and improves the safety of using the humidifier 1000.

[0052] Reference Figure 7 In some embodiments, a first guide 123 is provided in the silencing cavity 121, which is used to guide the condensate in the silencing cavity 121 to the silencing hole 122.

[0053] In this embodiment of the invention, by providing a first guide 123 in the silencing cavity 121, the condensate in the silencing cavity 121 can be more easily discharged through the silencing hole 122, further reducing the possibility of water accumulation in the silencing cavity 121, further reducing the possibility of bacteria growth in the misting assembly 100, and improving the safety of the humidifier 1000.

[0054] In some specific embodiments, at least a portion of the bottom wall of the silencing cavity 121 is inclined toward the silencing hole 122 to form a first guide 123.

[0055] In this embodiment of the invention, the first guide 123 has a simple structure and is easy to process. It does not require other parts to be set in the silencer cavity 121, which reduces the processing difficulty of the misting assembly 100 and reduces the cost of the misting assembly 100.

[0056] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, multiple silencing cavities 121 are provided, and each silencing cavity 121 is provided with at least one silencing hole 122.

[0057] In this embodiment of the invention, by setting multiple silencing chambers 121, the sound waves in the mist exhaust channel 111 will resonate with the multiple silencing chambers 121 and multiple silencing holes 122, which further improves the noise reduction effect of the noise reduction part 120 and effectively improves the noise problem of the humidifier 1000.

[0058] It should be understood that each silencing cavity 121 may be provided with one silencing hole 122, or two, three or other numbers of silencing holes 122, and the present invention does not limit this.

[0059] Reference Figures 2-5 In some embodiments, the noise reduction portion 120 is a single piece and defines a plurality of noise reduction cavities 121.

[0060] In this embodiment of the invention, the noise reduction part 120 is an integral piece, which is convenient to manufacture and also convenient to connect the noise reduction part 120 to the main body part 110, which is beneficial to improving the assembly efficiency of the fogging component 100.

[0061] Reference Figure 2 and Figure 3 In some specific embodiments, the noise reduction part 120 is a single piece located within the mist exhaust channel 111. The noise reduction part 120 includes a cylindrical structure 124. The inner side of the cylindrical structure 124 is used for water mist passage. Multiple partition plates 125 are integrally formed on the outer peripheral wall of the cylindrical structure 124. The side of the partition plate 125 away from the cylindrical structure 124 abuts against the inner wall of the mist exhaust channel 111. Multiple silencing cavities 121 are defined between the cylindrical structure 124, the multiple partition plates 125, and the inner wall of the mist exhaust channel 111. Each silencing cavity 121 is provided with a silencing hole 122 located on the cylindrical structure 124.

[0062] In this embodiment of the invention, the noise reduction part 120 is a single piece, which is convenient to manufacture and install, and the noise reduction part 120 is located inside the mist exhaust channel 111. In some application scenarios of the mist exhaust channel, the outer wall of the main body 110 is used to help define the water supply cavity 240 of the humidifier 1000. In this embodiment of the invention, by setting the noise reduction part 120 inside the mist exhaust channel 111, the risk of liquid in the water supply cavity 240 entering the silencing cavity 121 is avoided, the sealing of the silencing cavity 121 does not need to be considered, and the cost of the mist exhaust assembly 100 is reduced.

[0063] Reference Figure 4 and Figure 5 In other embodiments, the noise reduction portion 120 is a single piece located outside the main body portion 110. The noise reduction portion 120 includes a cylindrical structure 124, with multiple partition plates 125 disposed between the cylindrical structure 124 and the main body portion 110. Multiple sound-absorbing cavities 121 are defined between the cylindrical structure 124, the multiple partition plates 125, and the outer wall of the main body portion 110. Each sound-absorbing cavity 121 is provided with a sound-absorbing hole 122 located on the main body portion 110. Preferably, a sealing element is provided between the noise reduction portion 120 and the main body portion 110.

[0064] In this embodiment of the invention, the noise reduction part 120 is an integral piece, which is easy to manufacture and easy to install. Furthermore, the noise reduction part 120 is located on the outside of the main body part 110, which reduces the difficulty of connecting the noise reduction part 120 and the main body part 110 and helps to improve the production efficiency of the fogging assembly 100.

[0065] Reference Figures 6-10 In other embodiments, the noise reduction portion 120 includes a plurality of spaced sub-portions 126, each sub-portion 126 having at least one silencing cavity 121.

[0066] In other words, the noise reduction part 120 can be a single piece or a separate piece, as long as the noise reduction part 120 can define or participate in defining multiple noise reduction cavities 121. This invention does not impose any restrictions on this.

[0067] Reference Figures 2-5 In some embodiments, multiple silencing cavities 121 are provided, and each silencing cavity 121 is provided with at least one silencing hole 122. At least two silencing cavities 121 have different volumes.

[0068] The air inside the silencing cavity 121 and the silencing hole 122 can resonate with the sound wave, and the silencing cavity 121 and the silencing hole 122 connected to it have a natural resonant frequency. When the frequency of the sound wave is consistent with the natural resonant frequency, the resonance effect of the air inside the silencing cavity 121 and the silencing hole 122 is the best.

[0069] The volume of the anechoic chamber 121 affects the value of the inherent resonant frequency. In this embodiment of the invention, at least two anechoic chambers 121 have different volumes, which means there will be at least two different inherent resonant frequencies. This allows the noise reduction section 120 to reduce sound waves of different frequencies, increasing the frequency band that the noise reduction section 120 can reduce, and further increasing the noise reduction effect of the noise reduction section 120.

[0070] In some further embodiments, the volumes of the plurality of silencing cavities 121 are all different.

[0071] By using the above technical solution, more different inherent resonant frequencies are added, enabling the noise reduction section 120 to reduce more sound waves of different frequencies, further increasing the frequency band that the noise reduction section 120 can reduce, and further increasing the noise reduction effect of the noise reduction section 120.

[0072] In some embodiments, multiple silencing cavities 121 are provided, and each silencing cavity 121 is provided with a silencing hole 122. At least two silencing holes 122 have different opening sizes.

[0073] The size of the opening of the noise reduction hole 122 affects the value of the inherent resonant frequency. In this embodiment of the invention, at least two noise reduction holes 122 have different opening sizes, so there will be at least two different inherent resonant frequencies, which allows the noise reduction part 120 to reduce sound waves of different frequencies, increases the frequency band that the noise reduction part 120 can reduce, and further increases the noise reduction effect of the noise reduction part 120.

[0074] In some further embodiments, the opening sizes of the plurality of silencers 122 are all different.

[0075] By using the above technical solution, more different inherent resonant frequencies are added, enabling the noise reduction section 120 to reduce more sound waves of different frequencies, further increasing the frequency band that the noise reduction section 120 can reduce, and further increasing the noise reduction effect of the noise reduction section 120.

[0076] In some embodiments, at least a portion of the plurality of silencing cavities 121 are arranged in the extending direction of the mist exhaust channel 111, and at least two silencing cavities 121 are at different heights in the extending direction of the mist exhaust channel 111.

[0077] In this embodiment of the invention, at least two silencing cavities 121 have different heights in the extension direction of the mist exhaust channel 111, which indicates that at least two silencing cavities 121 have different volumes. This means that there will be at least two different inherent resonant frequencies, which allows the noise reduction part 120 to reduce sound waves of different frequencies, increasing the frequency band that the noise reduction part 120 can reduce, and further increasing the noise reduction effect of the noise reduction part 120.

[0078] In some embodiments, the height of the plurality of silencers 121 in the extension direction of the mist exhaust channel 111 gradually increases in the direction toward the mist exhaust port 112.

[0079] By employing the above technical solution, the number of silencing cavities 121 with different volumes is further increased, increasing the inherent resonant frequency. This allows the noise reduction section 120 to reduce sound waves of different frequencies, expanding the frequency band that the noise reduction section 120 can reduce, and further enhancing the noise reduction effect of the noise reduction section 120. In other embodiments, the height of the multiple silencing cavities 121 may gradually decrease in the extending direction of the mist exhaust channel 111; this invention does not limit this to a specific configuration.

[0080] Reference Figure 3 , Figure 8 and Figure 10 In some embodiments, at least a portion of the plurality of silencing cavities 121 are arranged circumferentially in the mist exhaust channel 111, and at least two silencing cavities 121 have different circumferential widths in the mist exhaust channel 111.

[0081] In this embodiment of the invention, if the circumferential widths of at least two anechoic cavities 121 are different, it means that the volumes of at least two anechoic cavities 121 are different, and there will be at least two different inherent resonant frequencies. This allows the noise reduction part 120 to reduce sound waves of different frequencies, increasing the frequency band that the noise reduction part 120 can reduce, and further increasing the noise reduction effect of the noise reduction part 120.

[0082] Reference Figure 2In some specific embodiments, the multiple silencing cavities 121 are divided into multiple groups, which are arranged in the extension direction of the mist exhaust channel 111. The multiple silencing cavities 121 in each group are arranged in the circumferential direction of the mist exhaust channel 111. The circumferential width of the multiple silencing cavities 121 in each group is different, but the height of the multiple silencing cavities 121 in each group in the extension direction of the mist exhaust channel 111 is the same, which reduces the processing difficulty of the noise reduction part 120 and reduces the cost of the mist outlet assembly 100.

[0083] Reference Figure 2 In some embodiments, the noise reduction portion 120 is provided with a first groove on the side facing the main body portion 110, and the main body portion 110 closes the opening of the first groove to define the sound-absorbing cavity 121.

[0084] In this embodiment of the invention, the noise reduction part 120 and the main body part 110 cooperate to define the silencing cavity 121. Compared with the technical solution where the noise reduction part 120 defines the silencing cavity 121 alone, this effectively simplifies the structure of the fogging assembly 100 and reduces the cost of the fogging assembly 100.

[0085] In some specific embodiments, the noise reduction part 120 is a single piece located within the mist exhaust channel 111. The noise reduction part 120 includes a cylindrical structure 124. The inner side of the cylindrical structure 124 is used for water mist passage. Multiple partition plates 125 are integrally formed on the outer peripheral wall of the cylindrical structure 124. Multiple first grooves are defined between the partition plates 125 and the cylindrical structure 124. The inner wall of the mist exhaust channel 111 closes the openings of the multiple first grooves, thereby defining multiple silencing chambers 121. Each silencing chamber 121 is provided with a silencing hole 122 located on the cylindrical structure 124.

[0086] Reference Figure 4 and Figure 5 In some other embodiments, a second groove is provided on the side of the main body 110 facing the noise reduction part 120, and the noise reduction part 120 closes the opening of the second groove to define the sound-absorbing cavity 121.

[0087] Specifically, the noise reduction part 120 is an integral part located on the outside of the main body part 110. The noise reduction part 120 includes a cylindrical structure 124. Multiple partition plates 125 are provided on the outer peripheral wall of the main body part 110. Multiple second grooves are defined between the outer peripheral wall of the main body part 110 and the multiple partition plates 125. The cylindrical structure 124 closes the openings of the multiple second grooves, thereby defining multiple silencing cavities 121. Each silencing cavity 121 is provided with a silencing hole 122 located on the main body part 110.

[0088] The present invention does not limit the formation of the silencing cavity 121, as long as the silencing cavity 121 can be connected to the mist exhaust channel 111 through the silencing hole 122.

[0089] In some embodiments, the noise reduction portion 120 is detachably connected to the main body portion 110.

[0090] The above technical solution makes it easy for users to separate the noise reduction part 120 from the main body 110, making it easier for users to clean the internal structure of the silencing cavity 121, further reducing the risk of bacteria growth in the silencing cavity 121, and improving the safety of using the humidifier 1000.

[0091] In some specific embodiments, the noise reduction component 120 includes a cylindrical structure 124, which is located inside or outside the main body component 110, and the cylindrical structure 124 is interference-fitted with the main body component 110. This technical solution further reduces the difficulty of installing and removing the noise reduction component 120 from the main body component 110.

[0092] In some other specific embodiments, the noise reduction part 120 and the main body part 110 can also be connected by snap-fit ​​connection, screw connection, plug connection or other detachable methods, and the present invention does not limit this.

[0093] Reference Figure 2 In some embodiments, the main body 110 includes a noise reduction section 120 located in the mist exhaust channel 111, and a silencer hole 122 is disposed in the noise reduction section 120. (Refer to...) Figure 4 In some embodiments, a noise reduction portion 120 is provided on the outer side of the main body 110, and a silencing hole 122 is provided on the inner wall of the mist exhaust channel 111. The present invention does not limit the specific location of the silencing hole 122, as long as the silencing cavity 121 is connected to the mist exhaust channel 111 through the silencing hole 122.

[0094] Reference Figure 9 In some embodiments, the noise reduction part 120 is located inside the mist exhaust channel 111, and the noise reduction part 120 is provided with a guide surface 127 for guiding the water mist to the mist exhaust port 112.

[0095] In this embodiment of the invention, the water mist can be guided by the guide surface 127, which reduces the loss of mist flow rate by the noise reduction part 120 and ensures the mist output of the humidifier 1000.

[0096] Reference Figures 11-14 In some embodiments, the main body 110 includes a mounting portion 113 and a mist guiding portion 114 connected together. The mounting portion 113 is used to connect with the housing 200 of the humidifier 1000 to define a mist-generating chamber 210 between the mounting portion 113 and the housing 200. The end of the mist guiding portion 114 away from the mounting portion 113 is provided with a mist outlet 112. The noise reduction portion 120 is disposed on the mist guiding portion 114 and / or the mounting portion 113.

[0097] In this embodiment of the invention, the mounting part 113 of the main body 110 is used to define the fog-generating chamber 210, which facilitates the connection between the fog-generating chamber 210 and the fog exhaust channel 111, which helps to simplify the structure of the humidifier 1000 and reduce the cost of the humidifier 1000.

[0098] In some embodiments, at least a portion of the cross-section of the mist guide portion 114 gradually decreases in the direction toward the mist outlet 112.

[0099] The above technical solution results in the cross-section of the mist exhaust channel 111 gradually decreasing in the direction near the mist exhaust port 112, which is beneficial to increasing the flow rate of water mist at the mist exhaust port 112 and increasing the mist output of the humidifier 1000.

[0100] In some further embodiments, the mounting part 113 is provided with a plurality of reinforcing ribs 115, which improves the structural strength of the main body 110 and helps to extend the service life of the misting assembly 100.

[0101] In some embodiments, the mounting portion 113 includes a first portion 1131 and a second portion 1132 connected together. The first portion 1131 communicates with the mist guiding portion 114 and is located below the mist guiding portion 114. The internal space of the first portion 1131 is used to accommodate the atomizing element 300 of the humidifier 1000.

[0102] The first part 1131 is located directly below the mist guiding part 114, so that the water mist atomized by the atomizing component 300 can directly enter the mist guiding part 114, which is beneficial to increasing the flow rate of water mist in the mist exhaust channel 111.

[0103] The internal space of the second part 1132 is connected to the internal space of the first part 1131. The second part 1132 is provided with a water inlet 116. The internal space of the second part 1132 is used to accommodate the communication component of the humidifier 1000. The communication component is used to control the opening and closing of the water inlet 116.

[0104] Reference Figures 11-14 According to an embodiment of the present invention, a humidifier 1000 includes: a housing 200, an atomizing element 300, and a mist outlet assembly 100 as described above. The housing 200 is provided with a mist-generating chamber 210, the atomizing element 300 is used to atomize the liquid in the mist-generating chamber 210, the mist outlet assembly 100 is disposed in the housing 200, and the mist exhaust channel 111 communicates with the mist-generating chamber 210.

[0105] According to an embodiment of the humidifier 1000, the mist outlet assembly 100 has a noise reduction portion 120 provided on the main body portion 110, which connects the mist exhaust channel 111 with the silencer hole 122 and the silencer cavity 121. When the sound wave propagates in the mist exhaust channel 111, it resonates with the air in the silencer hole 122 and the silencer cavity 121, reducing the energy of the sound wave and effectively improving the noise situation at the mist outlet 112. Furthermore, the noise reduction portion 120 also increases the thickness of the mist outlet assembly 100, increasing the difficulty for the sound wave to propagate outward through the mist outlet assembly 100, further reducing the noise passing through the mist outlet assembly 100, and effectively improving the noise problem when the humidifier 1000 is working.

[0106] In some embodiments, the atomizing element 300 is a heating element.

[0107] In this embodiment of the invention, when the humidifier 1000 is working, the heating element heats the liquid in the mist-generating chamber 210, causing the liquid to boil and generate steam, directly increasing the water vapor content in the air. The steam is released rapidly, which can increase the air humidity in a short time. The amount of steam is directly related to the heating power, making it easier to achieve stable humidity. When the water is heated to boiling, bacteria, viruses, and microorganisms in the water can be effectively killed, improving the safety of using the humidifier 1000.

[0108] It should be understood that in other embodiments, the atomizing element 300 may also be an ultrasonic oscillating plate, the atomizing element 300 may also include a wet curtain and a fan, and the atomizing element 300 may also have other structures, as long as the liquid can be converted into water mist, and the present invention does not limit this.

[0109] In some embodiments, the housing 200 includes a cylindrical portion 220 with openings at both ends. A spacer 221 is provided inside the cylindrical portion 220, which divides the internal space of the cylindrical portion 220 into upper and lower parts.

[0110] The housing 200 also includes a base 230, which is detachably disposed at the bottom of the cylindrical portion 220 and closes the bottom opening of the cylindrical portion 220. An electrical compartment for placing electrical components is formed between the spacer 221 and the base 230.

[0111] Atomizing element 300 is disposed on isolator 221. A portion of atomizing element 300 is located on the upper side of isolator 221 for atomizing liquid, and a portion of atomizing element 300 is located on the lower side of isolator 221 for connecting electrical components.

[0112] A labyrinth seal is provided between the atomizing element 300 and the isolating element 221 to seal the gap between the atomizing element 300 and the isolating element 221, preventing liquid on the upper side of the isolating element 221 from entering the electrical compartment and improving the safety of the humidifier 1000.

[0113] In some embodiments, the isolator 221 is provided with a mounting groove 222, the opening of the mounting groove 222 is upward, and the atomizing element 300 is disposed on the bottom wall of the mounting groove 222.

[0114] The mist-generating assembly 100 includes a main body 110, which includes a connected mounting portion 113 and a mist-guiding portion 114. A portion of the mounting portion 113 is located within a mounting groove 222 and is interference-fitted with the mounting groove 222. A mist-generating chamber 210 is defined between the internal space of the mounting portion 113 and the inner wall of the mounting groove 222.

[0115] The mist guiding part 114 is connected to the mounting part 113. The mist guiding part 114 defines a mist exhaust channel 111. The mist guiding part 114 extends upward, and the top of the mist guiding part 114 defines a mist exhaust port 112. A noise reduction part 120 is provided on the outer side of the mist guiding part 114.

[0116] A water replenishment chamber 240 is defined between the outer peripheral wall of the mist-generating assembly 100 and the inner wall of the cylindrical body portion 220. The mounting portion 113 includes a first portion 1131 and a second portion 1132 connected together. The first portion 1131 communicates with the mist-guiding portion 114 and is located below the mist-guiding portion 114. The internal space of the first portion 1131 is used to accommodate the atomizing element 300 of the humidifier 1000. The internal space of the second portion 1132 communicates with the internal space of the first portion 1131. A water inlet 116 is provided on the second portion 1132, which is used to connect the water replenishment chamber 240 and the mist-generating chamber 210.

[0117] The internal space of the second part 1132 is provided with a connecting component, which is used to control the opening and closing of the inlet 116.

[0118] The humidifier 1000 is configured such that when the liquid level in the misting chamber 210 is lower than a set height, the connecting component connects the water supply chamber 240 and the misting chamber 210, so that the water in the water supply chamber 240 is replenished to the misting chamber 210. When the liquid level in the misting chamber 210 reaches the set height, the connecting component disconnects the water supply chamber 240 and the misting chamber 210, so that the liquid level in the misting chamber 210 can be maintained at the set height.

[0119] Specifically, the connecting component includes a float and a closure. The float is disposed in the misting chamber 210 and fluctuates with the liquid level in the misting chamber 210. The float and the closure are in a driving relationship. When the liquid level in the water replenishment chamber 240 drops, the float drops and drives the closure to avoid the water inlet 116, allowing water in the water replenishment chamber 240 to be replenished into the misting chamber 210 through the water inlet 116. When the liquid level in the water replenishment chamber 240 rises to a set height, the float rises with the liquid level and drives the closure to close the water inlet 116. In other embodiments, a first sensor may be disposed in the misting chamber 210. The first sensor is adapted to detect the water level or water pressure in the misting chamber 210. The connecting component includes a solenoid valve adapted to connect the water replenishment chamber 240 and the misting chamber 210. The solenoid valve is configured to determine whether to connect the water replenishment chamber 240 and the misting chamber 210 based on the detection result of the first sensor.

[0120] It should be understood that the connecting component can also be other structures, as long as the liquid level in the misting chamber 210 can be maintained at a set height, and the present invention does not limit this.

[0121] In some embodiments, the housing 200 further includes a cover plate 250, which is disposed at the top end of the cylindrical portion 220 and connected to the upper end of the cylindrical portion 220 via a rotating locking unit, which may be threaded or screw-on. The cover plate 250 is used to cover the opening at the top of the water replenishment chamber 240 to prevent external debris from entering the water replenishment chamber 240. The cover plate 250 is provided with a clearance hole for avoiding the mist outlet assembly 100, and the water mist in the mist exhaust channel 111 is suitable for being discharged to the outside of the housing 200 through the mist exhaust port 112 and the clearance hole to humidify the air.

[0122] In some embodiments, the humidifier 1000 further includes a shielding assembly 400, which is connected to the inner wall of the clearance hole via a rotation locking unit. The mist outlet 112 of the mist outlet assembly 100 communicates with the shielding assembly 400, and a plurality of mist outlets 410 are provided on the periphery of the shielding assembly 400. Steam in the mist outlet channel 111 can enter the shielding assembly 400 through the mist outlets 112, and then be discharged to the periphery of the shielding assembly 400 through the mist outlets 410 to humidify the air. By providing the shielding assembly 400, steam can be prevented from flowing directly from the top, causing burns, thus improving the safety of using the humidifier 1000.
