DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] The terms "first", "second", "third" in the embodiments of the present application are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., and the meaning of "multiple groups" is at least two groups, such as two groups, three groups, etc., unless otherwise explicitly specified and limited.

[0024] In the related art, in the case of long-term high-power operation, the atomizing piece generates a large amount of heat to deform the base, so that a gap is generated between the atomizing piece and the plastic base, liquid is easy to penetrate into the atomizing piece through the gap, and the atomizing piece is easy to be damaged.

[0025] In order to solve the above problems, with reference to Figures 1 to 4 The present application discloses a kind of suspending atomizer 10, comprising: Float 1; Base 2, which is connected with the float 1; Atomizing piece 3, which is arranged on the base 2;And Spacing structure 4 is arranged between the atomizing piece 3 and the base 2, one end of the spacing structure 4 is fixedly connected with the atomizing piece 3, and the other end is fixedly connected with the base 2.

[0026] The spacing structure 4 of the present application is arranged between the atomizing piece 3 and the base 2, so that the base 2 does not directly contact the atomizing piece 3, and therefore the heat generated by the atomizing piece 3 during operation is not easy to transfer to the base 2, i.e. the base 2 is not easy to be deformed due to excessive heat, and therefore a gap is not easy to be generated between the base 2 and the atomizing piece 3, and liquid is not easy to penetrate into the atomizing piece 3 through the gap to damage it.

[0027] Further, the outer wall surface of the atomizing piece 3 is in contact with the inner wall surface of the spacing structure 4, and the outer wall surface of the spacing structure 4 is in contact with the base 2. The atomizing piece 3, the spacing structure 4 and the base 2 are connected together by extrusion, realizing interference fit, so that the three have sealing property and water penetration prevention function, and the structure is simple.

[0028] In some embodiments, refer to Figure 1 and Figure 4 The spacer structure 4 includes a first horizontal portion 41 and a first vertical portion 42 arranged circumferentially along the outer edge of the first horizontal portion 41. The first horizontal portion 41 and the first vertical portion 42 together form a mounting structure with a first annular mounting groove. The atomizing plate includes a first flat portion 32 and a first side portion 31 arranged circumferentially along the outer edge of the first flat portion 32. The atomizing plate 3 is installed entirely within the first annular mounting groove of the spacer structure 4. The base 2 includes a first flat wall 22 and a first side wall 21 arranged circumferentially along the outer edge of the first flat wall 22. The first horizontal portion 41 and the first vertical portion 42 together form a mounting structure with a second annular mounting groove. The spacer structure 4 is installed entirely within the second annular mounting groove. The first side wall 21, the first side portion 31, and the first vertical portion 42 are sequentially connected in contact with each other, and the first flat wall 22, the first flat portion 32, and the first horizontal portion 41 are sequentially connected in contact with each other. There are two contact surfaces between the atomizing plate 3 and the spacer structure 4, and two contact surfaces between the spacer structure 4 and the base 2. Therefore, by squeezing the atomizing plate 3, the spacer structure 4 and the base 2 together, it has a good water-proof capability and reduces the risk of water leakage from the atomizing plate 3.

[0029] In some embodiments, refer to Figure 1 and Figure 4 The first horizontal portion 41 is provided with a first vent 411, the atomizing plate includes a mist outlet 321, and the first flat wall 22 is provided with a first air outlet 221. The mist outlet 321, the first vent 411, and the first air outlet 221 are sequentially connected. When the atomizing plate 3 is working, it generates mist, which is quickly discharged from the mist outlet 321 through the first vent 411 and the first air outlet 221. The structure is simple.

[0030] In some embodiments, refer to Figure 1 and Figure 4 The first sidewall 21 is located below the first flat wall 22. The first sidewall 21, the first side portion 31 and the first vertical portion 42 are all arc-shaped wall portions, so as to achieve surface-to-surface contact between the atomizing plate 3 and the spacer structure 4, and surface-to-surface contact between the spacer structure 4 and the base 2, thereby further improving the water-proof capability.

[0031] In some embodiments, refer to Figure 1 and Figure 4To prevent the atomizing plate 3 from detaching from the base 2, the suspended atomizer 10 also includes a cover 5, which covers the first sidewall 21, with the atomizing plate 3 located between the cover 5 and the first flat wall 22. Specifically, the first sidewall 21 has a threaded hole, and the cover 5 is fixed to the first sidewall 21 by a screw connected to the threaded hole, making installation convenient. Optionally, the cover 5 is in contact with the first sidewall 21, providing better water resistance and reducing the risk of water leakage from the atomizing plate 3.

[0032] In some embodiments, refer to Figure 1 and Figure 4 The system also includes a gasket 6, one end of which abuts against the first flat portion 32, and the other end of which abuts against the first horizontal portion 41. The surfaces of the first flat portion 32 and the first horizontal portion 41 may be uneven due to processing errors, resulting in gaps between them after contact, leading to poor sealing. By placing the gasket 6 between the first flat portion 32 of the atomizing plate 3 and the first horizontal portion 41 of the spacer structure 4, the sealing performance between them is improved, providing better water resistance. Optionally, the gasket 6 can be a silicone sheet, which has a certain degree of plasticity. This ensures good sealing while allowing the atomizing plate 3 to have a certain degree of offset, enabling better vibration and mist output.

[0033] In some embodiments, the spacer structure 4 is made of a thermally conductive material, such as a metal thermally conductive material. Preferably, the spacer structure 4 is a high-temperature resistant and thermally conductive metal cover. Since the atomizing plate 3 is in contact with the spacer structure 4, the heat generated by the atomizing plate 3 is transferred to the thermally conductive spacer structure 4, which diffuses the heat around it. Because the spacer structure 4 is submerged in the liquid, it can exchange heat with the liquid, carrying away most of the heat from the spacer structure 4. Consequently, less heat is transferred to the base 2, making the base 2 less prone to deformation due to excessively high temperatures. This also prevents gaps from forming between the spacer structure 4 and the base 2, thus reducing the risk of damage to the atomizing plate 3 due to water seepage.

[0034] In some embodiments, the spacer structure 4 is made of a thermally insulating material, such as zirconia ceramic, special glass, polyimide, and polyetheretherketone. Since the atomizing plate 3 is in contact with the spacer structure 4, the heat generated by the atomizing plate 3 is transferred to the low thermal conductivity spacer structure 4. Because the spacer structure 4 has low thermal conductivity, the amount of heat transferred during heat exchange between the spacer structure 4 and the base 2 is relatively small. Therefore, the base 2 is less likely to be subjected to excessive heat and deform, meaning that gaps are less likely to form between the spacer structure 4 and the base 2. Consequently, the atomizing plate 3 is less likely to be damaged due to water seepage.

[0035] In some embodiments, refer to Figure 5 The system also includes a sealing ring 7, one end of which abuts against the first horizontal portion 41, and the other end of which abuts against the first flat wall 22. Due to processing errors, the surfaces of the first flat wall 22 and the first horizontal portion 41 are uneven. Therefore, even after the first flat wall 22 and the first horizontal portion 41 abut against each other, there may still be a small gap, resulting in poor sealing. By setting the sealing ring 7 between the first flat wall 22 of the base 2 and the first horizontal portion 41 of the spacer structure 4, the sealing performance between the first flat wall 22 of the base 2 and the first horizontal portion 41 of the spacer structure 4 is improved, providing better water resistance. Optionally, the sealing ring 7 is a silicone sheet, which has a certain degree of plasticity, thus ensuring good sealing performance.

[0036] Optionally, the float 1 is made of a material with a density lower than that of the liquid, so that the float 1 floats on the liquid.

[0037] Alternatively, float 1 can be made of a low-density material, such as wood or foam block, so that float 1 floats on the liquid.

[0038] Optionally, the base 2 is made of plastic.

[0039] Optionally, refer to Figure 1 and Figure 2 The float 1 includes an upper cover 11 and a housing 12, with the upper cover 11 covering the housing 12. A sealed first cavity 13 filled with gas is provided between the upper cover 11 and the housing 12. This facilitates the float 1 to float in the liquid and has a simple structure. Furthermore, the housing 12 is integrally formed with the base 2, reducing costs.

[0040] Optionally, refer to Figure 2 The base 2 includes a central part 23 and connecting arms 24 at both ends of the central part 23. The connecting arms 24 are fixedly connected to the float 1. The float 1 is disc-shaped. The two connecting arms 24 are symmetrically arranged around the center point of the float 1. In this way, the float 1 can maintain balance when floating on the liquid surface, thereby keeping the atomizing plate 3 in a predetermined position, so that the atomizing plate 3 can smoothly produce mist.

[0041] Optionally, refer to Figure 1 and Figure 3 A second cavity 14 is provided between the connecting arm 24 and the housing 12. The first sealed cavity is connected to the second sealed cavity, which further improves the buoyancy of the suspended atomizer 10.

[0042] The float 1 is connected to the base 2. Optionally, the float 1 and the base 2 are fixed together by a snap-fit ​​or by screws.

[0043] Optionally, the atomizing plate 3 is fixed on the top surface of the base 2 or the atomizing plate 3 is fixed on the bottom surface of the base 2. Preferably, the housing 12 and the base 2 are integrally formed.

[0044] Optionally, refer to Figures 4 to 6 The base 2 is located below the float 1. The float 1 has a mist outlet 15, and the mist outlet 321 of the atomizing plate 3 faces the mist outlet 15. The mist generated by the atomizing plate 3 is quickly discharged from the liquid through the mist outlet 15. Furthermore, the mist outlet 15 has a sound-absorbing structure 16. Even further, the sound-absorbing structure 16 includes a ring 161 and a plurality of fixing strips 162 evenly distributed around the outer circumference of the ring 161. One end of each fixing strip 162 is fixedly connected to the ring 161, and the other end is fixedly connected to the inner wall of the mist outlet 15. Optionally, the sound-absorbing structure 16 and the mist outlet 15 are integrally formed.

[0045] Optionally, the suspended atomizer 10 also includes a wire outlet. The atomizing plate 3 includes a wire, and the wire outlet passes sequentially through the first sidewall 21 and the first vertical portion 42. The wire and the wire outlet are sealed together. As a separate electronic component, the atomizing plate 3 needs to be conductive to function. To prevent water leakage from the atomizing plate 3, the wire of the atomizing plate 3 is led out from the wire outlet, and the wire and the wire outlet are sealed together, enabling the atomizing plate 3 to be energized and preventing water leakage. The structure is simple.

[0046] Optionally, refer to Figure 7 The base 2 has an annular stop portion 25 extending downward from the outer edge of the first air outlet 221 along its first flat wall 22. A sealing ring 7 is disposed on the outer periphery of the annular stop portion. The first horizontal portion 41 of the spacer structure 4 abuts against the annular stop portion 25. The thickness of the sealing ring 7 is greater than the height of the annular stop portion. When assembling the chassis, sealing ring 7, spacer structure 4, gasket 6, atomizing plate 3, and cover 5, the annular stop portion 25, the first side wall 21, and the first flat wall 22 work together to position the sealing ring 7 in the designated position. Then, the spacer structure 4, gasket 6, and atomizing plate 3 are placed sequentially inside the first side wall 21. Finally, the cover 5 is fixedly connected to the first side wall 21, completing the assembly. At this time, the cover 5 applies pressure to the atomizing plate 3, gasket 6, spacer structure 4, sealing ring 7, and first flat wall 22 in sequence, thus achieving mutual compression between the first flat wall 22, sealing ring 7, first horizontal portion 41, and first flat portion 32 to form a better seal.

[0047] Optionally, refer to Figure 8 and Figure 9The spacer structure 4 further includes a second vertical portion 43 arranged circumferentially along the inner side of the first horizontal portion 41. The base 2 also includes an annular stop portion 25 and a positioning groove 26. The positioning groove 26 is located between the first flat wall 22 and the annular stop portion 25. The second vertical portion 43 cooperates with the positioning groove 26 and is located above the first flat portion 32. The second vertical portion 43 keeps the wall of the first air outlet 221 of the base 2 away from the atomizing plate 3, thereby preventing the base 2 from directly contacting the atomizing plate 3 and allowing the spacer structure 4 to better suppress heat radiation to the base 2 when the atomizing plate 3 is working. Optionally, the top surface of the second vertical portion 43 is 1 mm to 10 mm higher than the surface of the first flat portion 32. Preferably, the top surface of the second vertical portion 43 is 8 mm higher or higher than the surface of the first flat portion 32, which can further improve the suppression effect on heat radiation of the atomizing plate 3 and facilitate EMC testing.

[0048] This invention also provides a humidifier, including the aforementioned suspended atomizer 10 and a water tank. The suspended atomizer 10 is placed in the water tank. When the water tank is filled with water, the suspended atomizer 10 floats on the water, while the atomizing plate 3 is below the float 1, i.e., the atomizing plate 3 is submerged in water. During operation, the atomizing plate 3 generates ultrasonic waves that turn the water into water mist particles, which rise from the water to the surface, thus achieving humidification. Due to the function of the partition, the base 2 is less likely to be subjected to excessive heat and deform, thereby preventing gaps from forming between the base 2 and the atomizing plate 3. Liquid is less likely to seep into the interior of the atomizing plate 3 through these gaps and cause damage. Therefore, this application is applicable to humidifiers that operate at high power for extended periods, and is particularly suitable for base 2 (made of plastic) which is prone to heat deformation.
