[0002] This application is based on and claims priority to Chinese Patent Application No. 2025101351094, filed on February 6, 2025, entitled "Humidifier", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of household appliances, and in particular to a humidifier. Background Technology

[0004] 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.

[0005] In related technologies, humidifiers are equipped with a maximum water level line. If the water level continues to be added after the maximum water level line has been reached, the humidifier may not work. Summary of the Invention

[0006] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a humidifier in which the float rises with the water level in the water chamber until the water inlet is closed. When the water level in the water chamber rises to a first set height, the float closes the water inlet, preventing further water addition and avoiding the risk of users adding too much water. This ensures that the water level in the water chamber will not exceed the first set height, thus guaranteeing the reliability of the humidifier's operation.

[0007] A humidifier according to an embodiment of the present invention includes: a housing, wherein a water-holding cavity is provided inside the housing, and a water inlet channel communicating with the water-holding cavity is provided inside the housing, wherein the water inlet channel has a water inlet located on the outer surface of the housing; an atomizing element disposed in the water-holding cavity to atomize liquid; and a float movably disposed in the water inlet channel to open or close the water inlet.

[0008] According to an embodiment of the present invention, a float is provided inside the housing of the humidifier. The float can rise to close the water inlet as the water level in the water chamber rises, or it can fall to open the water inlet as the water level rises. When the water level in the water chamber rises to a first set height, the float closes the water inlet, and water cannot be added further.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The following is for reference. Figures 1-16 A humidifier 100 according to an embodiment of the present invention is described.

[0048] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, a humidifier 100 includes: a housing 11, an atomizing element, and a float 5. The housing 11 has a water-holding chamber 111 and a mist outlet 112 communicating with the water-holding chamber 111. The housing 11 has a water inlet channel 118 communicating with the water-holding chamber 111. The water inlet channel 118 has a water inlet 1171 located on the outer surface of the housing 11. The atomizing element is disposed in the water-holding chamber 111 to atomize the liquid. The float 5 is movably disposed in the water inlet channel 118 to open or close the water inlet 1171.

[0049] When the user needs to use the humidifier 100, the atomizing element works to atomize the liquid in the water chamber 111 into water mist, and then discharges the water mist through the mist outlet 112 to improve the indoor air.

[0050] In this embodiment, a float 5 is provided inside the housing 11. The float 5 can float up and down with the water level in the water chamber 111. When the water level in the water chamber 111 rises to a first set height, the float 5 rises with the water level and rises to close the water inlet 1171. As the humidifier 100 continues to work, the water level in the water chamber 111 begins to drop. When the water level in the water chamber 111 drops below the first set height, the float 5 drops with the water level and opens the water inlet 1171, allowing the user to add water through the water inlet 1171.

[0051] When the water level in the water chamber 111 is lower than the first set height and water needs to be added, the float 5 opens the water inlet 1171, allowing the user to add water through the water inlet 1171 on the surface of the housing 11. During water addition, water enters the water supply channel 118 through the water inlet 1171 and then flows into the water chamber 111. When the water level in the water chamber 111 rises to the first set height, the float 5 closes the water inlet 1171, preventing further water addition and avoiding the risk of overfilling. This ensures that the water level in the water chamber 111 will not exceed the first set height, guaranteeing the reliability of the humidifier 100.

[0052] According to an embodiment of the humidifier 100 of the present invention, a float 5 is provided inside the housing 11. The float 5 can rise with the water level in the water chamber 111 to close the water inlet 1171, or it can fall with the water level to open the water inlet 1171. When the water level in the water chamber 111 rises to a first set height, the float 5 closes the water inlet 1171, so water cannot be added. This avoids the risk of the user adding too much water and ensures that the water level in the water chamber 111 will not exceed the first set height, thus ensuring the reliability of the humidifier 100.

[0053] In some embodiments, at least a portion of the cross-section of the float 5 is non-circular to prevent rotation.

[0054] The above technical solution restricts the rotation of the float 5 and the movement mode of the float 5, so that the float 5 can only move up and down at a set angle. When the float 5 moves upward, it can adapt to the shape of the water inlet 1171, thereby completely blocking the water inlet 1171 and ensuring the reliability of the float 5 in closing the water inlet 1171.

[0055] It should be noted that at least a portion of the float 5 is non-circular, and the non-circular shape can be triangular, rectangular, hexagonal, octagonal, elliptical, racetrack-shaped, etc. This application does not impose any restrictions on this.

[0056] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the water inlet channel 118 includes an upper portion 1184 and a lower portion 1185, the cross-sectional area of ​​the upper portion 1184 being smaller than the cross-sectional area of ​​the lower portion 1185, and the top opening of the upper portion 1184 defining the water inlet 1171; the float 5 includes a first portion 51 and a second portion 52, the cross-sectional area of ​​the first portion 51 being smaller than the cross-sectional area of ​​the second portion 52, the first portion 51 being located within the upper portion 1184, and the second portion 52 being located within the lower portion 1185.

[0057] In this embodiment, the float 5 includes a first part 51 and a second part 52. The first part 51 is located above the second part 52. The first part 51 is used to close the water inlet 1171. Therefore, the shape of the first part 51 needs to be adapted to the water inlet 1171. Since the water inlet 1171 does not need to be designed to be too large, the cross-sectional area of ​​the first part 51 is correspondingly designed to be smaller, reducing the material used in the float 5 and lowering the cost of the humidifier 100. The second part 52 is located below the first part 51. The second part 52 is used to cooperate with the water surface to drive the first part 51 to move up and down. The cross-sectional area of ​​the second part 52 is larger than that of the first part 51, increasing the contact area between the second part 52 and the water, and ensuring the reliability of the float 5 floating up and down with the water surface.

[0058] In this embodiment, the water inlet channel 118 includes an upper part 1184 and a lower part 1185. The cross-sectional area of ​​the upper part 1184 is smaller than that of the lower part 1185, so that the shape of the water inlet channel 118 is adapted to the shape of the float 5, further improving the reliability of the float 5 moving up and down.

[0059] In some embodiments, the cross-section of the upper portion 1184 is non-circular, and the first portion 51 matches the upper portion 1184.

[0060] In this embodiment, simply designing the first part 51 of the float 5 as non-circular can achieve the effect of restricting the rotation of the float 5 and ensure the reliability of the float 5 in closing the water inlet 1171.

[0061] It should be understood that in other embodiments, the lower portion 1185 may be non-circular, and the second portion 52 may match the lower portion 1185; the upper portion 1184 and the lower portion 1185 may both be non-circular, the first portion 51 may match the upper portion 1184, and the second portion 52 may match the lower portion 1185. The shapes of the upper portion 1184 and the lower portion 1185 may be the same or different, and this application does not limit them.

[0062] Reference Figure 3 , Figure 4 and Figure 7 In some further embodiments, a first mating surface 511 is provided on the top of the first part 51, and the first mating surface 511 surrounds the first part 51. The inlet 1171 is provided on the top wall of the upper part 1184, and a second mating surface 11841 is provided on the top wall of the upper part 1184 surrounding the inlet 1171. When the liquid level in the water-filled cavity 111 reaches a first set height, the float 5 rises until the first mating surface 511 and the second mating surface 11841 abut, thereby completely closing the inlet 1171 and ensuring the reliability of the float 5 in closing the inlet 1171.

[0063] The first mating surface 511 can be a plane, an inclined plane or a curved surface, and the shape of the second mating surface 11841 is adapted to the shape of the first mating surface 511, so that the first mating surface 511 and the second mating surface 11841 can fit together completely to close the water inlet 1171.

[0064] In some specific embodiments, the top of the first portion 51 has a cross-section that gradually narrows in the downward direction to form a conical surface at the top of the first portion 51. The conical surface is formed as a first mating surface 511, and the shape of the second mating surface 11841 is adapted to the shape of the first mating surface 511.

[0065] When the liquid level in the water-filled cavity 111 reaches the first set height, the first mating surface 511 and the second mating surface 11841 stop abutting. Since both the first mating surface 511 and the second mating surface 11841 are conical surfaces, the buoyancy increases the mating force between the first mating surface 511 and the second mating surface 11841, further ensuring the reliability of the first part 51 in closing the water inlet 1171.

[0066] In addition, both the first mating surface 511 and the second mating surface 11841 are conical surfaces, which can also play a guiding role, so that the first part 51 can accurately close the water inlet 1171, further ensuring the reliability of the first part 51 in closing the water inlet 1171.

[0067] In some embodiments, the inner peripheral wall of the upper portion 1184 is provided with a plurality of guide ribs 11842, and the plurality of guide ribs 11842 are distributed at intervals around the first portion 51.

[0068] The guide rib 11842 reduces the contact area between the inner peripheral wall of the first part 51 and the upper part 1184, thereby reducing the possibility of adhesion between the inner peripheral wall of the first part 51 and the upper part 1184 and ensuring the reliability of the float 5 moving up and down with the water level.

[0069] In some embodiments, the outer peripheral wall of the second portion 52 is provided with a plurality of guide protrusions 521, and the plurality of guide protrusions 521 slide in contact with the inner peripheral wall of the lower portion 1185 respectively.

[0070] In this embodiment, the second part 52 contacts the inner peripheral wall of the lower part 1185 through the guide protrusion 521, which reduces the contact area between the second part 52 and the inner peripheral wall of the lower part 1185, reduces the possibility of the second part 52 sticking to the inner peripheral wall of the lower part 1185, and ensures the reliability of the float 5 moving up and down with the water level.

[0071] In some specific embodiments, the cross-section of the second portion 52 is polygonal, and the connection between adjacent sidewalls of the second portion 52 defines a guide protrusion 521.

[0072] Through the above technical solution, the second part 52 can only contact the inner peripheral wall of the lower part 1185 through the guide protrusion 521, which reduces the possibility of the second part 52 sticking to the inner peripheral wall of the lower part 1185. In addition, in this embodiment, the structure of the second part 52 is simple and easy to process, which reduces the processing cost of the float 5.

[0073] It should be understood that the cross-section of the second part 52 can be in the shape of a triangle, rectangle, hexagon, octagon, etc.

[0074] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments, the water inlet channel 118 is provided with a bottom wall that blocks the stroke of the float 5, and the bottom wall is provided with a hollow area 1183 for water outlet.

[0075] In this embodiment, the water inlet channel 118 is provided with a bottom wall, which limits the possibility of the float 5 moving downwards and detaching from the water inlet channel 118, reduces the risk of the float 5 being lost, and ensures the reliability of the float 5's up-and-down movement. Furthermore, the bottom wall is provided with a perforated area 1183, allowing water entering the water inlet channel 118 through the water inlet to enter the water-holding cavity 111 through the perforated area 1183, and water in the water-holding cavity 111 can also enter the water inlet channel 118 through the perforated area 1183 to drive the float 5 up and down.

[0076] Reference Figure 4 , Figure 5 and Figure 7 In some embodiments, the housing 11 has a cylindrical extension 1181 and a bottom plate 1182. The extension 1181 is fixed to the housing 11 to define a bottom-open water channel 118. The bottom plate 1182 is detachably installed to the bottom of the extension 1181, and a hollow area 1183 is provided on the bottom plate 1182.

[0077] By defining the bottom-closed water inlet channel 118 through the extension 1181 and the base plate 1182, the difficulty of mold making for the housing 11 is reduced, thus lowering costs. When installing the float 5, it can be placed inside the water inlet channel 118 through the open bottom end of the extension 1181, and then the base plate 1182 is installed at the bottom of the extension 1181, preventing the float 5 from detaching from the water inlet channel 118. In this embodiment, the installation method of the float 5 is simple, reducing the cost of the humidifier 100.

[0078] Specifically, the extension 1181 and the base plate 1182 are detachably connected by a snap-fit ​​structure. The extension 1181 and the base plate 1182 can also be connected by screws, and this application does not limit this connection.

[0079] Reference Figure 2 and Figure 4In some embodiments, the top wall of the housing 11 is provided with a groove 1172, and the water inlet 1171 is located at the lowest point of the groove 1172.

[0080] When adding water, the user can directly add water into the groove 1172, which acts as a guide, eliminating the need for the user to align the water inlet 1171 with the humidifier 100, thus significantly improving the convenience of adding water. Furthermore, when the user adds water until the float 5 closes the water inlet 1171, it is difficult to stop adding water simultaneously, resulting in a small amount of water continuing to fall. In this embodiment, a groove 1172 is provided on the top wall of the housing 11, allowing excess water to be temporarily stored within it. As the humidifier 100 is used, the water level in the water chamber 111 decreases, the float 5 opens the water inlet 1171, and the water in the groove 1172 can then enter the water chamber 111 through the water inlet 1171 without user intervention, further improving the ease of use of the humidifier 100.

[0081] In some embodiments, the top wall of the housing 11 is provided with a mist outlet 112, and the water inlet 1171 is positioned below the mist outlet 112.

[0082] The above technical solution makes it easier for users to distinguish between the mist outlet 112 and the water inlet 1171, reducing the possibility of users adding water through the mist outlet 112. Furthermore, the water inlet 1171 is lower than the mist outlet 112, avoiding the risk of water flowing from the periphery of the water inlet 1171 to the mist outlet 112 when the user adds water, further improving the reliability of the humidifier 100.

[0083] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments, the housing 11 includes a main body 114 and a cover 117. The main body 114 is provided with a water-holding cavity 111 that is open at the top. The cover 117 is detachably disposed on the top of the main body 114 and closes the opening at the top of the water-holding cavity 111. A mist outlet 112, a water inlet 1171, and a water inlet channel 118 are all disposed on the cover 117.

[0084] Through the above technical solution, the cover 117 can be removed from the main body 114, making it convenient for users to clean and maintain the inside of the humidifier 100.

[0085] It should be noted that the cover portion 117 may overlap the main body portion 114 or be snapped onto the main body portion 114; this application does not impose any restrictions on this.

[0086] Reference Figure 8In some embodiments, the humidifier 100 further includes a main unit assembly 1 and a water tank assembly 2. The main unit assembly 1 includes a housing 11, an atomizing element, and a float 5. The water tank assembly 2 is provided with a water replenishment chamber 21. The main unit assembly 1 and the water tank assembly 2 are detachably connected so that the humidifier 100 has a first working state and a second working state. In the first working state, the main unit assembly 1 is separated from the water tank assembly 2 and the main unit assembly 1 can operate independently. In the second working state, the main unit assembly 1 is connected to the water tank assembly 2 and the water replenishment chamber 21 is selectively connected to the water holding chamber 111 for replenishing water to the water holding chamber 111.

[0087] When the user needs to use the humidifier 100 for a long time, the main unit component 1 can be set to the second working state, so that the main unit component 1 and the water tank component 2 can cooperate, so that the water replenishment chamber 21 can replenish the water holding chamber 111, eliminating the need for the user to frequently add water and extending the battery life of the humidifier 100; when the user needs to place the humidifier 100 on the table for use, the main unit component 1 can be removed from the water tank component 2 and placed on the table to work independently.

[0088] In this embodiment, the main unit component 1 can be used alone or in conjunction with the water tank component 2, which effectively expands the applicability of the humidifier 100 and improves its practicality.

[0089] Scenarios where main unit component 1 and water tank component 2 work together: The increased water storage capacity of water tank component 2 allows the humidifier 100 to continuously humidify for a longer period. In dry seasons, it can operate at a high humidification level for an extended time without requiring frequent refills. After a single refill, the humidifier continues to evaporate for a longer period, providing the user with a noticeable humidification effect.

[0090] Scenario for standalone operation of main unit 1: When the air is not dry enough, continuous long-term humidification is not required. The water stored in main unit 1 provides a small amount of humidification, avoiding the use of a large water tank, which could cause the water to smell bad or breed bacteria and cause secondary pollution if stored for a long time.

[0091] The humidifier 100 of this application embodiment evaporates different amounts of water under different working conditions, which can adapt to different air dryness scenarios. It solves the pain point that users of small water tank products often need to add water but still cannot achieve the air humidification effect. It also avoids the secondary pollution caused by the small amount of water evaporated each time in large water tank products, and the growth of bacteria or odor caused by long-term storage of water.

[0092] Reference Figure 8 , Figure 10 and Figure 11 In some embodiments, in the second operating state, the housing 11 is supported on the water tank assembly 2.

[0093] In this embodiment of the application, in the second working state, the housing 11 is supported on the water tank assembly 2. That is, the main unit assembly 1 is located on the upper side of the water tank assembly 2. Compared with the technical solution where the water tank assembly 2 is located on the upper side of the main unit assembly 1, the main unit assembly 1 does not need to bear the weight of the water tank assembly 2, so that the water tank assembly 2 can be constructed as a container with a larger capacity, further extending the battery life of the humidifier 100.

[0094] In some specific embodiments, the top of the water tank assembly 2 is provided with a first mounting opening 22 that communicates with the water replenishment chamber 21.

[0095] In the second working state, the main unit 1 is supported on the upper side of the water tank assembly 2, and the water holding chamber 111 can be connected to the water replenishment chamber 21 through the first installation opening 22.

[0096] In this embodiment, the water tank assembly 2 has a simple structure, which simplifies the structure of the water tank assembly 2 and reduces the cost of the humidifier 100.

[0097] In some embodiments, the outer peripheral wall of the housing 11 is provided with a stop portion 113. In the second working state, the stop portion 113 abuts against the edge of the first mounting opening 22, ensuring the stability of the main unit 1.

[0098] Reference Figure 2 , Figure 9 and Figure 10 In some embodiments, the housing 11 includes a main body 114 and a base 115, with the base 115 mounted to the main body 114.

[0099] The main body 114 is provided with a water-holding cavity 111. An installation space 116 can be defined between the main body 114 and the base 115. The installation space 116 is spaced apart from the water-holding cavity 111. The installation space 116 can be used to place components such as the control module of the main unit 1, the water pump 3, and the fan 6.

[0100] By assembling the main body 114 and the base 115 into part of the housing 11, the difficulty of mold making for the housing 11 is reduced, thus lowering costs. Specifically, the main body 114 and the base 115 are detachably connected via a snap-fit ​​structure, which facilitates later maintenance or replacement. The main body 114 and the base 115 can also be connected by screws; this application does not limit this connection.

[0101] In some embodiments, the end of the main body 114 protrudes outward to define a stop portion 113, and the base 115 engages with the stop portion 113 to be mounted to the main body 114.

[0102] In the second working state, the base 115 is inserted into the first mounting opening 22, and the stop portion 113 abuts against the edge of the first mounting opening 22. This effectively improves the reliability of the connection between the main unit assembly 1 and the water tank assembly 2.

[0103] In some embodiments, the humidifier 100 further includes a water pump 3, which is used to transport water in the water replenishment chamber 21 to the water holding chamber 111. The water pump 3 is disposed on the main unit assembly 1 and connected to the control module of the main unit assembly 1; or, the water pump 3 is disposed on the water tank assembly 2, and the water pump 3 is detachably connected to the control module of the main unit assembly 1.

[0104] When water needs to be added to the water-containing chamber 111, the water pump 3 operates, connecting the water replenishment chamber 21 to the water-containing chamber 111 and transporting the water in the water replenishment chamber 21 to the water-containing chamber 111, thus completing the water replenishment of the water-containing chamber 111. When the water-containing chamber 111 does not need to be replenished, the water pump 3 stops operating.

[0105] In this embodiment, water can be transported in the water supply chamber 21 by the water pump 3, which is simple in structure and reduces the cost of the humidifier 100.

[0106] The control module can be connected to components such as the atomizing element, water pump 3, and fan 6 to control the operating state of the humidifier 100. Since the main unit 1 only needs to use the water pump 3 when in the second operating state, it is only necessary to ensure that the water pump 3 is connected to the control module during this state. In some specific embodiments, the water pump 3 can be directly connected to the control module and mounted on the main unit 1. In other embodiments, the water pump 3 can be housed within the water tank assembly 2 and detachably connected to the control module. When the main unit 1 is in the second operating state, the main unit 1 is connected to the water tank assembly 2, and the water pump 3 is connected to the control module. When the main unit 1 is in the first operating state, the water pump 3 is disconnected from the control module.

[0107] Reference Figure 10 and Figure 11 In some embodiments, the host component 1 is provided with a first mating member 13 electrically connected to the control module, the water tank component 2 is provided with a first trigger member 23, and the humidifier 100 is configured such that: in a second working state, the first trigger member 23 triggers the first mating member 13 to make the control module electrically connected to the water pump 3, and in a first working state, the first trigger member 23 moves away from the first mating member 13 to make the control module disconnected from the water pump 3.

[0108] Through the above technical solution, when the main unit component 1 is in the second working state, the first trigger 23 triggers the first mating component 13, and the control module is electrically connected to the water pump 3, so that the control module can control the working state of the water pump 3 and can also provide current to the water pump 3; when the main unit component 1 is not in the second working state, the water pump 3 is not needed. In order to ensure the reliability of the humidifier 100, when the main unit component 1 is not in the second working state, the first trigger 23 moves away from the first mating component 13, so that the control module is disconnected from the water pump 3, thus avoiding the possibility of the water pump 3 working when it is not in the second working state.

[0109] For example, when the main unit 1 is in the first working state, the control module is disconnected from the water pump 3, which avoids the possibility of external substances being sucked into the water pump 3 and improves the reliability of the humidifier 100.

[0110] It should be noted that the first mating component 13 can be a position detection sensor, used to detect whether the host component 1 is in the second working state. When the first trigger 23 triggers the position detection sensor, the control module obtains the information of the position detection sensor and then controls the electrical connection with the water pump 3. When the first trigger 23 moves away from the first mating component 13, the control module obtains the information of the position detection sensor and then controls the circuit to be disconnected from the water pump 3.

[0111] In some other embodiments, the first mating component 13 is a first switch, which is electrically connected between the control module and the water pump 3. In the second working state, the first switch is closed so that the water pump 3 and the control module are electrically connected.

[0112] In this embodiment, the first mating component 13 is configured as a switch between the water pump 3 and the control module, which simplifies the structure of the humidifier 100 and reduces the cost of the humidifier 100.

[0113] In some embodiments, the first switch is a Hall element 131, and the first trigger 23 is a magnetic element 231. Preferably, the magnetic element 231 is a permanent magnet.

[0114] When the main unit 1 is in the second operating state, it is mounted on the water tank assembly 2. The magnetic element 231 on the water tank assembly 2 is close to the Hall element 131 on the main unit 1. Under the influence of the magnetic field of the magnetic element 231, the Hall element 131 conducts current, thus electrically connecting the water pump 3 and the control module. When the main unit 1 is not in the second operating state (e.g., the first operating state), the Hall element 131 moves away from the magnetic element 231, and the Hall element 131 is removed from the magnetic field of the magnetic element 231, causing the Hall element 131 to disconnect the circuit, thus disconnecting the control module from the water pump 3.

[0115] In this embodiment, the first switch and the first trigger 23 have simple structures, which reduces the cost of the humidifier 100.

[0116] In some other embodiments, the first switch may also be a normally open switch.

[0117] When the main unit 1 is in the second working state, the first trigger 23 contacts the normally open switch to close the normally open switch, thus electrically connecting the water pump 3 and the control module. When the main unit 1 is not in the second working state, the first trigger 23 separates from the normally open switch, and the normally open switch is in the open state, thus disconnecting the control module from the water pump 3.

[0118] In this embodiment, the first switch and the first trigger 23 have simple structures, which reduces the cost of the humidifier 100.

[0119] It should be understood that the first switch is not limited to Hall element 131 and normally open switch, but can also be other forms of switch, and this application does not limit this.

[0120] Reference Figure 12 and Figure 13 In some embodiments, the humidifier 100 further includes a water circuit assembly 4, which is disposed in the water tank assembly 2. The water circuit assembly 4 is detachably connected to the water inlet of the water pump 3. The water inlet of the water circuit assembly 4 is connected to the water replenishment chamber 21 and the water inlet is located at the bottom of the water replenishment chamber 21.

[0121] In this embodiment, the water pump 3 can be connected to the bottom of the water supply chamber 21 via the water circuit assembly 4, allowing the water pump 3 to draw water from the bottom of the water supply chamber 21. This means that all water in the water supply chamber 21 can be transported to the water holding chamber 111, maximizing the utilization of the water resources in the water supply chamber 21 and further extending the operating time of the humidifier 100. Furthermore, the water circuit assembly 4 is detachably connected to the water inlet of the water pump 3, without affecting the disassembly of the main unit assembly 1 and the water tank assembly 2, thus improving the reliability of the humidifier 100.

[0122] In some embodiments, the water circuit assembly 4 includes a support member 41 and an inlet pipe 42. The support member 41 is installed to the water tank assembly 2. The first end of the inlet pipe 42 is fixed to the support member 41 for detachable connection with the water pump 3. The second end of the inlet pipe 42 extends to the bottom of the water replenishment chamber 21.

[0123] Because the main unit 1 is located on the upper side of the water tank assembly 2 in the second working state, the first end of the water inlet pipe 42 can be fixed to the upper end of the water tank assembly 2 by means of the support member 41, which improves the convenience of connecting the water inlet pipe 42 to the water pump 3.

[0124] In some specific embodiments, the support member 41 includes a first connecting pipe 411, the lower end of which is connected to the first end of the water inlet pipe 42, and the upper end of which is inserted into the water inlet of the water pump 3.

[0125] In this embodiment, the connection between the water circuit component 4 and the water pump 3 is simple, which improves the ease of use of the humidifier 100.

[0126] In some embodiments, the support member 41 is detachably mounted on the water tank assembly 2.

[0127] Through the above technical solution, the support component 41 is detachably connected to the water tank assembly 2, which facilitates the replacement of the support component 41 and reduces the maintenance cost of the humidifier 100.

[0128] In some specific embodiments, the support member 41 is snapped to the inner wall of the water replenishment cavity 21 to facilitate the installation and removal of the support member 41; in other embodiments, the support member 41 may also be installed on the inner wall of the water replenishment cavity 21 by screws, and this application does not limit this.

[0129] In some embodiments, the water circuit assembly 4 further includes a filter module 43, which is disposed at the second end of the water inlet pipe 42.

[0130] The above technical solution reduces the possibility of impurities in the water replenishment chamber 21 entering the water holding chamber 111, improves the purity of the water in the water holding chamber 111, and enhances the safety of the humidifier 100.

[0131] In some embodiments, the water channel assembly 4 is detachable from the water tank assembly 2.

[0132] Through the above technical solution, the water circuit component 4 and the water tank component 2 can be detachably connected, which facilitates the replacement of the water circuit component 4 and reduces the maintenance cost of the humidifier 100.

[0133] In some specific embodiments, the water circuit assembly 4 includes a support member 41, an inlet pipe 42, and a filter module 43. The support member 41 is snap-fitted to the inner wall of the upper end of the water supply chamber 21. The support member 41 includes a first connecting pipe 411, the lower end of which is connected to the first end of the inlet pipe 42, and the upper end of which is inserted into the inlet end of the water pump 3. The filter module 43 is disposed at the second end of the inlet pipe 42 and is screw-fitted to the bottom of the water supply chamber 21.

[0134] In this embodiment, the connection between the water circuit component 4 and the water tank component 2 is simple, which reduces the cost of the humidifier 100.

[0135] It should be understood that the connection method between the support 41 and the water tank assembly 2, and the connection method between the filter module 43 and the water tank assembly 2, can also be plug-in, screw-in, etc., and this application does not limit this.

[0136] Reference Figure 10 , Figure 11 and Figure 14In some embodiments, the water-filling cavity 111 is provided with a drain outlet 1111, and the main unit 1 is provided with a shielding component 12 for closing and opening the drain outlet 1111. In a first working state, the shielding component 12 closes the drain outlet 1111, and in a second working state, the shielding component 12 opens the drain outlet 1111. The drain outlet 1111 is connected to the water supply cavity 21.

[0137] In the first working state, the main unit 1 operates independently. At this time, the shielding component 12 closes the drain outlet 1111 to prevent water in the water chamber 111 from flowing out through the drain outlet 1111 and wetting the table and the ground, thus ensuring the reliability of the independent operation of the main unit 1.

[0138] In the second working state, the main unit 1 is connected to the water tank 2, and the shielding component 12 opens the drain outlet 1111. When the user adds water through the inlet 1171, the water in the water chamber 111 can enter the water replenishment chamber 21 through the drain outlet 1111, thereby adding water to the water replenishment chamber 21.

[0139] The above technical solutions further improve the convenience of water addition for users.

[0140] In some embodiments, the water tank assembly 2 is provided with a second trigger 25, and the humidifier 100 is configured such that: in a second working state, the second trigger 25 cooperates with the shielding assembly 12 to cause the shielding assembly 12 to open the drain outlet 1111, and in a first working state, the second trigger 25 moves away from the shielding assembly 12 to cause the shielding assembly 12 to close the drain outlet 1111.

[0141] When the main unit 1 is in the second working state, the second trigger 25 triggers the blocking component 12, which opens the drain outlet 1111, allowing water in the water-holding chamber 111 to enter the water supply chamber 21 through the drain outlet 1111. When the main unit 1 is in the first working state, the second trigger 25 moves away from the blocking component 12, causing the drain outlet 1111 to close, preventing water in the water-holding chamber 111 from flowing out through the drain outlet 1111 and wetting the table and the ground, thus ensuring the reliability of the independent operation of the main unit 1.

[0142] Through the above technical solution, when the main unit component 1 is in the second working state, the second trigger 25 can cooperate with the shielding component 12 to automatically open the drain outlet 1111 without the need for manual operation by the user, thus improving the convenience of using the humidifier 100.

[0143] In some embodiments, the shielding assembly 12 includes a shielding member 121, which is movable relative to the main unit assembly 1 for closing and opening the drain outlet 1111; the second trigger member 25 is configured as a push rod, which pushes the shielding member 121 to open the drain outlet 1111 when the main unit assembly 1 switches to the second working state.

[0144] In this embodiment, the shielding component 12 and the second trigger 25 have simple structures, which reduces the cost of the humidifier 100.

[0145] In some embodiments, the shielding assembly 12 further includes an elastic element 122, which applies a first force to the shielding member 121, the first force causing the shielding member 121 to tend to close the drain outlet 1111.

[0146] Through the above technical solution, in the first working state, without the action of the push rod, the first force applied by the elastic element 122 to the blocking element 121 enables the blocking element 121 to stably close the drain outlet 1111, ensuring the reliability of the main unit 1 when working alone and avoiding the risk of water leakage from the drain outlet 1111.

[0147] In some specific embodiments, the first trigger 23 and the second trigger 25 are both disposed on the support 41, which simplifies the overall structure of the humidifier 100 and reduces the cost of the humidifier 100.

[0148] In other embodiments, the blocking component 12 can also be configured as an electrically driven structure and connected to the control module. For example, the blocking component 12 can be a solenoid valve. When the main unit 1 is in the second working state, the control module controls the blocking component 12 to open the drain outlet 1111, and when the main unit 1 is in the first working state, the control module controls the blocking component 12 to close the drain outlet 1111. Other cases are also possible, as long as the drain outlet 1111 can be closed in the first working state and opened in the second working state.

[0149] In some embodiments, the main unit 1 includes a water baffle 14 disposed around the drain outlet 1111, the water baffle 14 including a first opening 141 communicating with the water-holding cavity 111, the first opening 141 being located above the drain outlet 1111.

[0150] Through the above technical solution, when the water level in the water-holding chamber 111 reaches the height of the first opening 141, the excess water in the water-holding chamber 111 will enter the water replenishment chamber 21 through the drain outlet 1111. This allows a certain amount of water to be retained in the water-holding chamber 111, avoiding the possibility that all the water in the water-holding chamber 111 will flow out through the drain outlet 1111, thus ensuring the reliability of the humidifier 100.

[0151] Reference Figure 15 and Figure 16 In some embodiments, the humidifier 100 further includes a fan 6, which is disposed on the main unit 1 and connected to the control module of the main unit 1. The housing 11 is provided with a first air inlet area 119, and the fan 6 is used to drive the air flowing in from the first air inlet area 119 to drive water mist out of the main unit 1.

[0152] In this embodiment, the host component 1 is equipped with a fan 6, which allows the fan 6 to blow the water mist in the liquid-containing chamber into the room, effectively increasing the mist output of the humidifier 100.

[0153] In some embodiments, the first air intake area 119 is disposed on the side wall of the main unit component 1.

[0154] When the main unit 1 is in the first working state or the second working state, the fan 6 can directly take in air through the first air inlet area 119 of the side wall.

[0155] Reference Figure 15 and Figure 16 In some embodiments, the first air intake area 119 is disposed on the bottom surface of the main unit assembly 1. The water tank assembly 2 is provided with a second air intake area 24 that communicates with the water replenishment chamber 21. In the second working state, the first air intake area 119 communicates with the water replenishment chamber 21, and the fan 6 takes in air through the first air intake area 119, the water replenishment chamber 21, and the second air intake area 24.

[0156] When the main unit 1 is in the first working state, the main unit 1 directly takes in air through the first air intake area 119 on the bottom surface. When the main unit 1 is in the second working state, the fan 6 takes in air through the first air intake area 119, the water replenishment chamber 21 and the second air intake area 24.

[0157] The above technical solution increases the distance between the air inlet area and the mist outlet 112, avoiding the influence of the air inlet on the mist outlet airflow and ensuring the reliability of the mist output of the humidifier 100.

[0158] In some embodiments, the first air intake area 119 is disposed on the bottom surface of the main unit component 1, and the main unit component 1 is further provided with a support foot 15 protruding from the bottom surface.

[0159] When the main unit 1 is in the first working state, the main unit 1 is supported on the table or the ground by the support foot 15, which increases the distance between the bottom of the main unit 1 and the table or the ground, making it easier for the first air intake area 119 to take in air.
