Description

[0001] This application claims priority to Chinese Patent Application No. 202510750854.X, filed on June 5, 2025, entitled "Humidifier and Method of Using the Same", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of humidifier technology, and in particular to a humidifier main unit and a humidifier. Background Technology

[0003] The most common way humidifier main units produce mist is through atomization, which uses high-frequency electronic oscillation and resonance to break down the liquid molecule structure and produce naturally drifting water mist.

[0004] In related technologies, the humidifier main unit includes a main unit with an integrated water tank for holding the liquid to be atomized. When the water tank needs to be cleaned, the user needs to hold the main unit to clean it. This cleaning process may cause liquid to enter the main unit, potentially leading to short circuits or other problems within the main unit's electrical circuitry. Utility Model Content

To this end, this invention proposes a humidifier main unit and a humidifier that can independently clean the water tank, thereby effectively preventing cleaning water from entering the main unit and ensuring the safety of the circuitry inside the humidifier main unit.

[0006] This application provides a humidifier main unit, including:

[0007] Atomizer;

[0008] The main unit has a placement slot;

[0009] A water tank is detachably installed in the placement slot. The bottom of the water tank is provided with a first through hole, which is connected to the atomizer. The first through hole is used to allow liquid to pass through and flow to the atomizer.

[0010] A sealing structure is disposed between the placement groove and the water tank, and is arranged around the first through hole. The sealing structure is used to at least seal the gap between the main body and the bottom of the water tank and around the first through hole.

[0011] The fixing structure includes a first fixing structure and a second fixing structure that cooperate with each other. The first fixing structure is disposed on the main body of the host, and the second fixing structure is disposed on the water tank. When the water tank is assembled into the placement slot, the first fixing structure and the second fixing structure cooperate with each other, so that the water tank and the main body of the host tightly press the sealing structure.

[0012] According to some embodiments of the present invention, the first fixing structure includes a first magnetic attracting member, the second fixing structure includes a second magnetic attracting member, the first magnetic attracting member is at least partially facing the second magnetic attracting member, and the first magnetic attracting member and the magnetic attracting member are magnetically connected.

[0013] According to some embodiments of the present invention, the first magnetic attractor and / or the second magnetic attractor are arranged in a ring structure and surround the sealing structure.

[0014] According to some embodiments of the present invention, a plurality of the first magnetic attractor and / or the second magnetic attractor are provided, and the plurality of the second magnetic attractors are respectively provided around the sealing structure.

[0015] According to some embodiments of the present invention, a plurality of second magnetic elements and / or a plurality of second magnetic elements are evenly spaced around the sealing structure.

[0016] According to some embodiments of the present invention, the placement slot includes a mounting base plate, the atomizer is disposed on the mounting base plate, and the first magnetic suction member is disposed inside the mounting base plate and is not exposed at the bottom of the placement slot.

[0017] According to some embodiments of the present invention, the first fixing structure includes a first snap-fit ​​structure, the second fixing structure includes a second snap-fit ​​structure, and the first snap-fit ​​structure and the second snap-fit ​​structure are snap-fit ​​connected.

[0018] According to some embodiments of the present invention, the first snap-fit ​​structure is disposed on the side wall of the placement groove, and the second snap-fit ​​structure is disposed on the side wall of the water tank.

[0019] According to some embodiments of the present invention, the bottom of the placement groove is provided with a second through hole communicating with the first through hole, and the atomizer is located in the second through hole; the water tank includes an outer end facing the placement groove, and the outer end is provided with an annular protrusion around the first through hole, and the annular protrusion extends at least partially into the second through hole;

[0020] The sealing structure includes:

[0021] The sealing gasket includes at least one of a first periphery and a second periphery, the first periphery extending toward the second through hole and sealingly connected to the circumference of the annular flange, and the second periphery extending toward the outer end and sealingly connected to the outer end.

[0022] A cover is disposed in the placement groove and at least partially covers the sealing gasket on the side facing the outer end.

[0023] Secondly, this application discloses a humidifier, comprising:

[0024] The aforementioned humidifier main unit;

[0025] A water tank, installed on the water tank, is used to supply liquid water to the water tank.

[0026] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: In the application stage, the water tank is detachably installed in the placement slot, and a water tank is usually placed above the humidifier. The water tank adds liquid water to the water tank, and the liquid water flows from the first through hole to the atomizer. The atomizer converts the liquid water into water mist and disperses it. The first fixing structure and the second fixing structure cooperate with each other to provide a force that brings the water tank and the main body closer together. The water tank and the main body are tightly pressed against the sealing structure. Thus, the sealing structure seals the gap between the placement slot and the bottom of the water tank, and around the first through hole. The sealing structure can effectively prevent liquid water from flowing into the placement slot, thereby preventing liquid water from flowing into the main body. Therefore, the safety of the circuitry inside the main body is effectively guaranteed.

[0027] During the cleaning phase of the water tank, the cooperation between the first and second fixing structures is released, allowing the operator to remove the water tank from the main unit for separate cleaning without having to clean both together. This effectively prevents cleaning water from flowing into the main unit during the cleaning phase, ensuring the safety of the circuitry within the main unit. Furthermore, cleaning the water tank separately from the main unit makes cleaning the water tank more convenient.

[0028] Moreover, the sealed structure prevents water from flowing into the gap between the water tank and the main unit, ensuring water utilization and preventing water accumulation in the gap that could lead to bacterial growth and affect user health. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] This application discloses a humidifier main unit 10. Please refer to [link / reference]. Figures 1 to 3 The device includes a main unit 100, an atomizer 200, a water tank 300, a fixing structure 400, and a sealing structure 500. The main unit 100 has a placement slot 110, and the atomizer 200 is disposed at the bottom 340 of the water tank or at the bottom of the placement slot 110. The water tank 300 is detachably disposed within the placement slot 110. The bottom 340 of the water tank has a first through hole 310, which connects to the atomizer 200. The first through hole 310 allows liquid to pass through and flow to the atomizer 200, which converts liquid water into water mist. The sealing structure 500 is disposed in both the placement slot 110 and the water tank. Between 300 and surrounding the first through hole 310, the sealing structure 500 is used to at least seal the gap between the main body 100 and the bottom 340 of the water tank and located around the first through hole 310; the fixing structure 400 includes a first fixing structure 410 and a second fixing structure 420 that cooperate with each other, the first fixing structure 410 is provided on the water tank 300, and the second fixing structure 420 is provided on the main body 100; when the water tank 300 is assembled in the placement slot 110, the first fixing structure 410 and the second fixing structure 420 cooperate with each other, so that the water tank 300 and the main body 100 tightly press the sealing structure 500.

[0044] Specifically, during application, the water tank 300 is detachably installed within the placement slot 110. A water tank 20 is typically placed above the humidifier. Liquid water is added to the water tank 300 from the water tank 20. The liquid water flows from the first through-hole 310 to the atomizer 200, which converts the liquid water into a mist and disperses it. The first fixing structure 410 and the second fixing structure 420 cooperate to provide a force that brings the water tank 300 and the main unit 100 closer together. The water tank 300 and the main unit 100 tightly press against the sealing structure 500. Thus, the sealing structure 500 seals the gap between the placement slot 110 and the bottom 340 of the water tank, and around the first through-hole 310. The sealing structure 500 effectively prevents liquid water from flowing into the placement slot 110, thereby preventing liquid water from flowing into the main unit 100. Therefore, the safety of the circuitry within the main unit 100 is effectively guaranteed.

[0045] During the cleaning phase of the water tank 300, the cooperation between the first fixing structure 410 and the second fixing structure 420 is released, allowing the operator to remove the water tank 300 from the main unit 100 for separate cleaning without having to clean both together. This effectively prevents cleaning water from flowing into the main unit 100 during the cleaning phase, ensuring the safety of the circuitry within the main unit 100. Furthermore, the water tank 300 is cleaned separately from the main unit 100, making cleaning the water tank 300 more convenient.

[0046] Moreover, by setting up the sealing structure 500, water can be prevented from flowing into the gap between the water tank 300 and the main unit 100. On the one hand, this ensures the water utilization rate, and on the other hand, it ensures that water does not accumulate in the gap, which could lead to the growth of bacteria and thus affect the user's health.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 The first fixing structure 410 includes a first magnetic attractor 411, which is disposed at the bottom of the placement groove 110; the second fixing structure 420 includes a second magnetic attractor 421, which is disposed at the bottom 340 of the water tank. The first magnetic attractor 411 is at least partially opposite the second magnetic attractor 421, thereby the first magnetic attractor 411 and the second magnetic attractor 421 can be magnetically connected vertically. One of the first magnetic attractor 411 and the second magnetic attractor 421 can be a permanent magnet or an electromagnetic component, and the other can be a permanent magnet, an electromagnetic component, or a metal body capable of magnetic connection.

[0048] Understandably, when the water tank 300 is assembled into the placement slot 110 of the main unit 100, the first magnetic member 411 and the second magnetic member 421 are magnetically connected vertically. Thus, the first magnetic member 411 provides a force to the water tank 300 toward the bottom of the placement slot 110 through the magnetic attraction of the second magnetic member 421. More precisely, it provides a force to the bottom 340 of the water tank to press against the sealing structure 500. Therefore, the water tank 300 and the main unit 100 can tightly press against the sealing structure 500. The sealing structure 500 seals the gap between the placement slot 110 and the bottom 340 of the water tank and is located around the first through hole 310. The sealing structure 500 can effectively prevent liquid water from flowing into the placement slot 110, thereby preventing liquid water from flowing into the main unit 100. Therefore, the safety of the circuit inside the main unit 100 is effectively guaranteed.

[0049] When the water tank 300 needs to be cleaned, the user only needs to pull the water tank 300 away from the main unit 100 to overcome the magnetic attraction between the first magnetic member 411 and the second magnetic member 421, and then the water tank 300 can be removed from the main unit 100. Thus, the water tank 100 and the main unit 100 can be cleaned independently.

[0050] In one possible embodiment, please refer to Figure 2 and Figure 3 The first magnetic attractor 411 and / or the second magnetic attractor 421 are arranged in a ring structure, for example, the first magnetic attractor 411 and / or the second magnetic attractor 421 are arranged in a circular ring and surround the sealing structure 500. It can be understood that the magnetic attraction between the first magnetic attractor 411 and / or the second magnetic attractor 421 is located on the periphery of the sealing structure 500, thereby providing a sufficiently large and uniform force to bring the water tank 300 and the main body 100 closer to each other, further enabling the water tank 300 and the main body 100 to better press the sealing structure 500 tightly, so as to ensure that the sealing structure 500 can tightly seal the gap between the placement groove 110 and the bottom 340 of the water tank and located around the first through hole 310. The sealing structure 500 can effectively prevent liquid water from flowing into the placement groove 110, thereby preventing liquid water from flowing into the main body 100.

[0051] Instead of the structure of the second magnetic member 421 described above, in another possible embodiment, please refer to Figure 2 and Figure 3Multiple first magnetic attractors 411 and / or second magnetic attractors 421 are provided, and the multiple first magnetic attractors 411 and / or second magnetic attractors 421 are respectively disposed around the perimeter of the sealing structure 500. Furthermore, the multiple first magnetic attractors 411 and / or multiple second magnetic attractors 421 are evenly spaced around the perimeter of the sealing structure 500. Of course, the multiple first magnetic attractors 411 and / or multiple second magnetic attractors 421 may not need to be evenly spaced around the perimeter of the sealing structure 500. For example, multiple first magnetic attractors 411 are provided, and the multiple first magnetic attractors 411 are evenly distributed around the perimeter of the sealing structure 500; similarly, multiple second magnetic attractors 421 are provided, and the multiple second magnetic attractors 421 are evenly distributed around the perimeter of the sealing structure 500. The number of first magnetic attractors 411 and second magnetic attractors 421 is equal, and they are arranged in a one-to-one correspondence.

[0052] It is understood that the first magnetic suction member 411 and / or the second magnetic suction member 421 are evenly arranged around the sealing structure 500. The magnetic attraction between the first magnetic suction member 411 and the second magnetic suction member 421 is located on the periphery of the sealing structure 500, thereby providing a sufficiently large and uniform force to bring the water tank 300 and the main body 100 closer to each other. This further enables the water tank 300 and the main body 100 to better press the sealing structure 500 tightly, so as to ensure that the sealing structure 500 can tightly seal the gap between the placement groove 110 and the bottom 340 of the water tank and located around the first through hole 310. The sealing structure 500 can effectively prevent liquid water from flowing into the placement groove 110, thereby preventing liquid water from flowing into the main body 100.

[0053] In some embodiments, please refer to Figures 2 to 3 The placement slot 110 includes a mounting base plate 120, which has a second through hole 121. The atomizer 200 is disposed inside the mounting base plate 120 and opposite the second through hole 121. Liquid water can flow through the first through hole 310 to the second through hole 121 and then to the atomizer 200, whereby the atomizer 200 converts the liquid water into water mist. The first magnetic suction member 411 is disposed inside the mounting base plate 120 and is not exposed at the bottom of the placement slot 110. Thus, the first magnetic suction member 411 and the second magnetic suction member 421 are magnetically connected in a non-contact manner.

[0054] Understandably, the first magnetic component 411 is housed within the mounting base 120 and not exposed at the bottom of the placement slot 110. This design isolates and seals the first magnetic component 411, effectively preventing the influence of external environmental factors such as dust and liquids, thus improving the waterproof and dustproof performance of the main unit 100. The first magnetic component 411 and the second magnetic component 421 have no physical contact wear, reducing component wear, extending service life, and lowering operating noise. Furthermore, the first magnetic component 411 does not require opening holes in the mounting base 120 for pre-reserved connection structures, simplifying the housing design and enabling long-distance or offset transmission.

[0055] In some embodiments, please refer to Figure 2 , Figures 4 to 6 The first fixing structure 410 includes a first snap-fit ​​structure 412, and the second fixing structure 420 includes a second snap-fit ​​structure 422. The first snap-fit ​​structure 412 and the second snap-fit ​​structure 422 are snap-fitted together. When the water tank 300 needs to be assembled into the placement slot 110, the user presses the water tank 300 into the placement slot 110, and the bottom 340 of the water tank is pressed downward against the sealing structure 500. At the same time, the first snap-fit ​​structure 412 and the second snap-fit ​​structure 422 are snap-fitted together, so that the bottom 340 of the water tank is kept pressed downward against the sealing structure 500. Thus, the sealing structure 500 seals the gap between the placement slot 110 and the bottom 340 of the water tank and around the first through hole 310. The sealing structure 500 can effectively prevent liquid water from flowing into the placement slot 110. When it is necessary to disassemble the sink 300, the user needs to apply force upwards to the sink 300 to separate the first snap-fit ​​structure 412 from the second snap-fit ​​structure 422, so that the sink 300 can be disassembled for independent cleaning.

[0056] In a specific structural form, please refer to Figure 6 The first snap-fit ​​structure 412 is disposed on the side wall of the placement groove 110, and the second snap-fit ​​structure 422 is disposed on the side wall of the water tank 300. For example, the first snap-fit ​​structure 412 is configured as a groove in the side wall of the placement groove 110, and the second snap-fit ​​structure 422 is configured as a protrusion in the side wall of the water tank 300. Thus, the first snap-fit ​​structure 412 and the second snap-fit ​​structure 422 can be snapped together, thereby keeping the bottom 340 of the water tank pressed tightly against the sealing structure 500. Thus, the sealing structure 500 seals the gap between the bottom 340 of the placement groove 110 and the gap around the first through hole 310, and the sealing structure 500 can effectively prevent liquid water from flowing into the placement groove 110.

[0057] In another specific structural form, the first snap-fit ​​structure 412 is configured as a protrusion on the side wall of the placement groove 110, and the second snap-fit ​​structure 422 is configured as a groove on the side wall of the water tank 300. Thus, the first snap-fit ​​structure 412 and the second snap-fit ​​structure 422 can be snapped together, thereby keeping the bottom 340 of the water tank pressed against the sealing structure 500.

[0058] In some embodiments, please refer to Figure 2 and Figure 3The water tank 300 includes an outer end 330 facing the placement tank 110. The outer end 330 is provided with an annular protrusion 320 located around the first through hole 310. That is, the first through hole 310 is connected to the inner side of the annular protrusion 320. The annular protrusion 320 extends at least partially into the second through hole 121. The sealing structure 500 is circumferentially disposed around the annular protrusion 320 and is sealed to the periphery of the annular protrusion 320.

[0059] It is understood that the annular flange 320 is at least partially inserted into the second through hole 121 to communicate with it. Thus, the first through hole 310 and the second through hole 121 are connected through the annular flange 320. In application, liquid water flows from the first through hole 310 into the annular flange 320, and then from the annular flange 320 into the second through hole 121, thereby flowing towards the atomizer 200. It can be seen that the bottom of the placement groove 110, through the setting of the annular flange 320, has a sealing effect on the gap between the placement groove 110 and the bottom 340 of the water tank, thereby effectively preventing liquid water from flowing into the placement groove 110, and thus preventing liquid water from flowing into the main body 100.

[0060] Furthermore, by providing the annular protrusion 320, the sealing structure 500 is sealed to the annular protrusion 320, thereby the sealing structure 500 and the water tank 300 can be tightly sealed to prevent liquid water from flowing into the placement tank 110 from the gap between the sealing structure 500 and the water tank 300, and thus prevent liquid water from flowing into the main body 100.

[0061] The sealing structure 500 includes a sealing gasket 510, which includes at least one of a first perimeter portion 511 and a second perimeter portion 512. For example, the sealing gasket 510 includes both the first perimeter portion 511 and the second perimeter portion 512. The first perimeter portion 511 and the second perimeter portion 512 are both generally arranged in annular shape, and the second perimeter portion 512 is connected to the inner periphery of the first perimeter portion 511. The first perimeter portion 511 extends toward the second through hole 121 and is sealed to the periphery of the annular protrusion 320. The second perimeter portion 512 extends toward the outer end 330 and is sealed to the outer end 330. It is understandable that, through the setting of the first surrounding portion 511 and the second surrounding portion 512, the sealing gasket 510 has a sufficiently large contact area with the placement groove 110 and the water tank 300. The sealing gasket 510 can effectively seal the gap between the placement groove 110 and the bottom 340 of the water tank and located around the first through hole 310, thereby preventing liquid water from flowing into the placement groove 110 and thus ensuring the safety of the circuit inside the main unit 100.

[0062] Furthermore, the sealing structure 500 also includes a cover 520, which is connected to the placement groove 110. The cover 520 at least partially covers the side of the sealing gasket 510 facing the outer end 330, that is, the upper side of the sealing gasket 510, thereby fixing the sealing gasket 510 to the bottom of the placement groove 110 to ensure that the sealing gasket 510 is in close contact with the bottom of the placement groove 110.

[0063] Specifically, the cover 520 is arranged in a ring shape. A positioning post is provided on the side of the cover 520 away from the water tank 300. The positioning post passes through a sealing gasket 510 and extends into the bottom of the placement groove 110. Then, a fixing screw is threadedly connected to the positioning post from the inside of the main body 100, thereby fixing the cover 520 to the bottom of the placement groove 110. This presses the sealing gasket 510 against the bottom of the water tank 300, thus ensuring a tight seal between the sealing gasket 510 and the bottom of the placement groove 110. Therefore, the sealing gasket 510 effectively prevents liquid water from flowing into the placement groove 110 through the gap between the sealing gasket 510 and the placement groove 110, thereby preventing liquid water from entering the main body 100.

[0064] This application also discloses a humidifier, including the humidifier main unit 10 and the water tank 20 described above. The water tank 20 is disposed on the water tank 300 and is used to supply liquid water to the water tank 300.

[0065] It is understood that the humidifier uses the aforementioned humidifier main unit 10. During application, the water tank 300 is detachably installed in the placement slot 110. A water tank 20 is typically placed on top of the humidifier. The water tank 20 adds liquid water to the water tank 300. The liquid water flows from the first through-hole 310 to the atomizer 200, which converts the liquid water into a mist and disperses it. The first fixing structure 410 and the second fixing structure 420 cooperate to provide a force that brings the water tank 300 and the main unit 100 closer together. The water tank 300 and the main unit 100 are tightly pressed against the sealing structure 500. Thus, the sealing structure 500 seals the gap between the placement slot 110 and the bottom 340 of the water tank, and around the first through-hole 310. The sealing structure 500 effectively prevents liquid water from flowing into the placement slot 110, thereby preventing liquid water from flowing into the main unit 100. Therefore, the safety of the circuitry within the main unit 100 is effectively guaranteed.

[0066] During the cleaning phase of the water tank 300, the cooperation between the first fixing structure 410 and the second fixing structure 420 is released, allowing the operator to remove the water tank 300 from the main unit 100 for separate cleaning without having to clean both together. This effectively prevents cleaning water from flowing into the main unit 100 during the cleaning phase, ensuring the safety of the circuitry within the main unit 100. Furthermore, the water tank 300 is cleaned separately from the main unit 100, making cleaning the water tank 300 more convenient.

[0067] Moreover, by setting up the sealing structure 500, water can be prevented from flowing into the gap between the water tank 300 and the main unit 100. On the one hand, this ensures the water utilization rate, and on the other hand, it ensures that water does not accumulate in the gap, which could lead to the growth of bacteria and thus affect the user's health.
