[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 7 As shown, a heating humidifier with an anti-dumping structure comprises a humidifying main unit 1 and a cover 2, wherein the cover 2 can be connected to the humidifying main unit 1 in an openable or closed manner and encloses a steam generating chamber 101, wherein the cover 2 is provided with a steam passage 201 and an anti-dumping structure 3, wherein the anti-dumping structure 3 comprises a valve seat assembly 4, wherein a quick assembly and disassembly structure is provided between the valve seat assembly 4 and the cover 2, and the anti-dumping structure 3 can be detachably connected to the steam passage 201 through the quick assembly and disassembly structure;

[0027] This anti-dumping structure 3 can be disassembled from the cover body, which is convenient for users to clean the anti-dumping structure, keep the inside and outside of the anti-dumping structure clean, and is convenient for installation and maintenance;

[0028] In addition, the valve seat assembly 4 is provided with an installation cavity 401, and a sealing weight 9 is movably arranged in the installation cavity 401. The valve seat assembly 4 is provided with a steam inlet 402 connecting the steam generating cavity 101 and the installation cavity 401 in the upright position corresponding to the installation cavity 401, and the valve seat assembly 4 is provided with a steam outlet 403 in the tilted position corresponding to the installation cavity 401. When the humidifier is tilted, the sealing weight 9 slides from the upright position to the tilted position and blocks the steam outlet 403.

[0029] When the humidifier is accidentally tipped over, the sealing weight 9 blocks the steam outlet 403 by gravity when tilting, preventing the water in the steam generating chamber 101 from flowing out, thereby improving the safety of the humidifier.

[0030] In this embodiment, the mounting cavity 401 and the sealing weight 9 are in a truncated cone structure which is wide at the top and narrow at the bottom, and the shape of the sealing weight 9 matches the shape of the lower half of the mounting cavity 401; when the sealing weight 9 is in the upright position of the mounting cavity 401, due to the matching shapes, the mounting cavity 401 can position the sealing weight 9 to prevent the sealing weight 9 from shaking, and the truncated cone structure can drive the sealing weight 9 to move when the humidifier is tilted in any direction, and because it is a truncated cone structure, when the humidifier is tilted into a horizontal state, the side walls of the mounting cavity 401 are inclined, thereby ensuring that the sealing weight 9 can slide from the upright position to the tilted position of the mounting cavity 401.

[0031] In addition, the sealing weight 9 can be a metal block with a truncated cone structure, or a metal block with a truncated cone structure, but an elastic silicone plate is connected to the sealing end face, or an elastic silicone block with a truncated cone structure, but a metal block with a certain weight is placed inside the elastic silicone block. The elastic silicone plate or the elastic silicone block can improve the sealing effect of the steam outlet 403.

[0032] The steam inlet 402 is opened on the side wall of the installation cavity 401 and is spaced apart from the sealing weight 9; the steam outlet 403 is opened on the top wall of the installation cavity 401 and is concentric with the installation cavity 401; the steam inlet 402 is opened on the side wall, and even when the sealing weight 9 is in the upright position of the installation cavity 401, the steam inlet 402 will not be blocked, and the steam outlet 403 is opened at the center axis position, so that when the sealing weight 9 slides to the tilted position at any angle, it is ensured that the sealing end face of the sealing weight 9 is blocked on the blocked steam outlet 403 in an eccentric position.

[0033] A plurality of supporting convex ribs 41 are evenly distributed on the wall surface of the installation cavity 401 in the circumferential direction. The plurality of supporting convex ribs 41 are extended along the depth direction of the installation cavity 401. When the humidifier is tilted, the sealing weight 9 slides on at least two supporting convex ribs 41 and is spaced apart from the steam inlet 402 through the supporting convex ribs 41.

[0034] In addition to enabling the sealing weight 9 to be spaced apart from the steam inlet 402, the surface of the supporting rib 41 has an arc-shaped structure. When the sealing weight 9 slides from the upright position to the tilted position, the friction between the two can be reduced, making the sliding of the sealing weight 9 smoother and guiding the sealing weight 9. After the sealing weight 9 blocks the steam outlet 403, the sealing weight 9 is stuck between the two supporting ribs 41, which can prevent the sealing weight 9 from shaking left and right, thereby ensuring the sealing effect on the steam outlet 403.

[0035] The valve seat assembly 4 includes a valve seat 5 and a valve cover 6. The top of the valve seat 5 is provided with an annular resting end surface 502. The valve cover 6 is fastened to the valve seat 5 and sealed against the resting end surface 502, so that a sealing joint surface is formed between the valve seat 5 and the valve cover 6. The fastening connection of the connecting boss and the connecting hole enables the valve cover 6 and the valve seat 5 to be sealed against each other, eliminating the sealing ring structure, reducing the installation process, improving production efficiency and reducing production costs;

[0036] The bottom of the valve seat 5 is provided with a mounting groove 501, and the valve cover 6 and the mounting groove 501 together define a mounting cavity 401, and the sealing weight 9 is limited in the mounting cavity 401, and the steam outlet 403 is provided on the valve cover 6; the valve seat assembly 4 is assembled by combining the valve seat 5 and the valve cover 6, so that the sealing weight 9 is conveniently placed in the mounting groove 501, and the valve cover 6 is used to limit the sealing weight 9.

[0037] The valve seat assembly 4 is also provided with a reflux chamber 404 separated from the installation chamber 401, the side wall of the reflux chamber 404 is provided with a condensate inlet 405 connected to the steam channel 201, the bottom wall of the reflux chamber 404 is provided with a condensate reflux port 406 connected to the steam generating chamber 101, and the valve seat assembly 4 is connected with a one-way valve structure that can open or seal the condensate reflux port 406; during the humidification process, after the high-temperature steam forms condensate in the steam channel 201, it will initially flow to the anti-dumping structure 3, and then flow back to the steam generating chamber 101 through the condensate inlet 405, the reflux chamber 404 and the condensate reflux port 406 for reuse.

[0038] The one-way valve structure includes an elastic valve membrane 8, on which a buckling protrusion 81 extends axially, and a valve membrane support 51 is provided in the condensate return port 406, and a buckling hole 511 is opened on the valve membrane support 51, and the buckling protrusion 81 is buckled with the buckling hole 511, so that the elastic valve membrane 8 is sealed and held below the condensate return port 406;

[0039] The one-way valve structure of this structure can prevent the condensate return port 406 from being often opened during the heating process, which affects the heating efficiency of the steam generating chamber 101. In addition, when the humidifier is tilted, the elastic valve membrane 8 can seal the condensate return port 406.

[0040] During use, when a certain amount of condensed water accumulates in the reflux chamber 404, the condensed water pushes open the elastic valve membrane 8 because the pressure it is subjected to is greater than the elastic potential energy of the elastic valve membrane 8, so that the condensed water reflux port 406 opens and flows into the steam generating chamber 101. After the condensed water in the reflux chamber 404 decreases, the elastic valve membrane 8 uses its elastic potential energy to reset itself and seal the condensed water reflux port 406 again.

[0041] The valve seat assembly 4 also includes a cover 7, which is fastened to the top of the valve seat 5; the diameter of the cover 7 is larger than the diameter of the valve seat 5, and the two are spaced apart from each other to form a circumferential steam exhaust gap 407; the cover 7 is in an arc-shaped structure that is high in the middle and low on all sides; on the one hand, the cover 7 can prevent the steam discharged from the steam inlet 402 from rising and then directly out through the cover body 2, but instead uses the steam exhaust gap 407 to exhaust to all sides, which helps to disperse the steam into the air, and when the humidifier is instantly tilted, before the sealing weight 9 blocks the steam outlet 403, a small amount of water droplets may splash out from the steam outlet 403, so the cover 7 can, on the other hand, block the splashing water droplets, thereby improving the safety of the humidifier.

[0042] An inner retaining ring 52 is extended upward from the edge of the valve seat 5 and is arranged around the outer periphery of the steam outlet 403. An outer retaining ring 71 is extended downward from the edge of the cover 7. The outer retaining ring 71 is arranged on the outside of the inner retaining ring 52, and the outer retaining ring 71 and the inner retaining ring 52 are staggered up and down. The outer retaining ring 71 and the inner retaining ring 52 are staggered up and down so that after the steam passes through the steam exhaust gap 407, a downward guide is formed, which can reduce the speed of the steam, prevent the steam from being discharged from the cover body 2 too quickly, and improve the quality of the steam.

[0043] In addition, a plurality of connection holes 521 are provided on the outer circumference of the inner retaining ring 52, and a plurality of support columns 72 are extended from the bottom surface of the cover 7 corresponding to the connection holes 521. The support columns 72 are seated above the connection holes 521, and screws are passed through the connection holes 521 and the support columns 72 to fasten the cover 7 to the valve seat 5.

[0044] The steam channel 201 is in a trumpet shape that is wide at the top and narrow at the bottom. The shape of the steam channel 201 helps to diffuse the steam into the air. The upper section is provided with an inclined condensate return surface 202. The condensate formed in the steam channel 201 will drip onto the condensate return surface 202 and flow into the reflux cavity 404 toward the center. The lower section of the steam channel 201 is provided with a channel neck 203, which is located at the center of the steam channel 201.

[0045] The quick-release structure includes a snap-on protrusion 21 arranged on the inner side of the channel neck 203 and a rotating snap-on groove 408 arranged on the outer side of the valve seat assembly 4. The rotating snap-on groove 408 cooperates with the circular rotation of the snap-on protrusion 21, so that the anti-dumping structure 3 can be detachably connected in the steam channel 201; the anti-dumping structure 3 can be disassembled, which is convenient for users to clean the anti-dumping structure, keep the anti-dumping structure 3 clean inside and outside, and facilitate installation and maintenance.

[0046] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
