[0026] The present application is further described below in combination with the drawings and embodiments.

[0027] As shown in Figs. 1 to 7, a heating type humidifier with an anti-toppling structure comprises a humidifying host 1 and a cover body 2, the cover body 2 is detachably connected on the humidifying host 1 and encloses a steam generating cavity 101, the cover body 2 is provided with a steam passage 201 and an anti-toppling structure 3, the anti-toppling structure 3 comprises a valve seat assembly 4, the valve seat assembly 4 and the cover body 2 are provided with a quick detach structure, and the anti-toppling structure 3 is detachably connected in the steam passage 201 through the quick detach structure.

[0028] The anti-toppling structure 3 can be detached from the cover, facilitating the user to clean the anti-toppling structure, keeping the inside and outside of the anti-toppling structure clean, and facilitating installation and maintenance. The valve seat assembly 4 is internally provided with an installation cavity 401, the installation cavity 401 is movably provided with a sealing weight 9, the valve seat assembly 4 is provided with a steam inlet 402 corresponding to the standing position of the installation cavity 401, the steam inlet 402 is in communication with the steam generating cavity 101 and the installation cavity 401, and the valve seat assembly 4 is provided with a steam outlet 403 corresponding to the toppling position of the installation cavity 401. When the humidifier is toppling, the sealing weight 9 slides from the standing position to the toppling position and blocks the steam outlet 403.

[0029] After the humidifier is accidentally toppling, the sealing weight 9 blocks the steam outlet 403 by gravity when it is tilted, preventing the water in the steam generating cavity 101 from flowing out, and improving the safety of the humidifier.

[0030] In the embodiment, the installation cavity 401 and the sealing weight 9 are in the shape of a circular truncated cone structure, the shape of the sealing weight 9 matches the lower half of the installation cavity 401. When the sealing weight 9 is in the standing position of the installation cavity 401, the installation cavity 401 can position the sealing weight 9 due to the matching shapes, avoiding the sealing weight 9 from shaking. The mutual circular truncated cone structure enables the sealing weight 9 to move when the humidifier is toppling in any direction. Since the structure is a circular truncated cone, when the humidifier is toppling to a horizontal state, the side wall of the installation cavity 401 is arranged to be inclined, thereby ensuring that the sealing weight 9 can slide from the standing position to the toppling position of the installation cavity 401.

[0031] In addition, the sealing weight 9 can be a metal block in the shape of a circular truncated cone, or a metal block in the shape of a circular truncated cone, but connected with an elastic silica gel plate on the sealing end face, or an elastic silica gel block in the shape of a circular truncated cone, but with a metal block with a certain weight placed in the elastic silica gel block. The elastic silica gel plate or the elastic silica gel block can improve the sealing effect on the steam outlet 403.

[0032] The steam inlet 402 is arranged on the side wall of the installation cavity 401 and is spaced apart from the sealing weight 9. The steam outlet 403 is arranged on the top wall of the installation cavity 401 and is concentric with the installation cavity 401. The steam inlet 402 is arranged on the side wall, so that the sealing weight 9 will not block the steam inlet 402 when it is in the standing position of the installation cavity 401. The steam outlet 403 is arranged on the central axis, so that when the sealing weight 9 slides to the toppling position at any angle, the sealing end face of the sealing weight 9 is ensured to block the steam outlet 403 at an eccentric position.

[0033] The wall surface of the installation cavity 401 is circumferentially and uniformly provided with a plurality of support ribs 41, which are arranged along the depth direction of the installation cavity 401, and when the humidifier is tilted, the sealing weight 9 slides on at least two support ribs 41 and is spaced apart from the steam inlet 402 by the support ribs 41.

[0034] In addition to being able to space the sealing weight 9 and the steam inlet 402, the surface of the support rib 41 is arc-shaped, which can reduce the friction between the sealing weight 9 and the steam inlet 402 when the sealing weight 9 slides from the vertical position to the tilted position, making the sliding of the sealing weight 9 more smooth, guiding the sealing weight 9, and preventing the sealing weight 9 from shaking left and right after the sealing weight 9 blocks the steam outlet 403, ensuring the blocking effect of 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 a circumferential resting end face 502, the valve cover 6 is tightly connected with the valve seat 5 and is sealed and pressed on the resting end face 502, so that a sealed joint surface is formed between the valve seat 5 and the valve cover 6, the tight connection of the connecting column and the connecting hole enables the valve cover 6 to be sealed against the valve seat 5, eliminating the structure of the sealing ring, reducing the installation process, improving production efficiency and reducing production cost;

[0036] The bottom of the valve seat 5 is recessed with an installation groove 501, the valve cover 6 and the installation groove 501 jointly define an installation cavity 401, and the sealing weight 9 is limited in the installation cavity 401, and the steam outlet 403 is provided on the valve cover 6; the valve seat assembly 4 is assembled by the valve seat 5 and the valve cover 6, which facilitates the placement of the sealing weight 9 in the installation 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 backflow cavity 404 separated from the installation cavity 401, the side wall of the backflow cavity 404 is provided with a condensed water inlet 405 communicating with the steam channel 201, the bottom wall of the backflow cavity 404 is provided with a condensed water backflow port 406 communicating with the steam generating cavity 101, and the valve seat assembly 4 is connected with a one-way valve structure that can open or seal the condensed water backflow port 406; during the humidification process, after the high-temperature steam forms condensed water in the steam channel 201, it will initially flow to the anti-tilting structure 3, then flow to the steam generating cavity 101 through the condensed water inlet 405, the backflow cavity 404 and the condensed water backflow port 406 for reuse.

[0038] The one-way valve structure comprises an elastic valve membrane 8, a fastening convex column 81 axially extending on the elastic valve membrane 8, a valve membrane support 51 arranged in the condensed water return port 406, and a fastening hole 511 arranged on the valve membrane support 51, wherein the elastic valve membrane 8 is fastened and matched with the fastening convex column 81 and the fastening hole 511, and is sealed and abutted below the condensed water return port 406;

[0039] The one-way valve structure can prevent the condensed water return port 406 from being opened frequently during the heating process, thereby affecting the heating efficiency of the steam generating cavity 101, and the elastic valve membrane 8 can seal the condensed water return port 406 when the humidifier is tilted.

[0040] During use, when a certain amount of condensed water is accumulated in the return cavity 404, the condensed water pushes open the elastic valve membrane 8, so that the condensed water return port 406 is opened and flows into the steam generating cavity 101, and when the condensed water in the return cavity 404 is reduced, the elastic valve membrane 8 is reset by the elastic potential energy, and the condensed water return port 406 is sealed again.

[0041] The valve seat assembly 4 further comprises a cover 7 fastened and connected above the valve seat 5, wherein the cover 7 has a diameter larger than that of the valve seat 5, and is arranged in a spaced-apart manner above and below the valve seat 5 to form a circumferential steam exhaust gap 407, the cover 7 has an arc-shaped structure with a middle part being high and four peripheral parts being low, and the cover 7 can prevent the steam exhausted from the steam inlet port 402 from rising directly through the cover body 2, but exhausts the steam to the periphery through the steam exhaust gap 407, which helps to disperse the steam into the air, and the cover 7 can also block the splashing water droplets to improve the safety of the humidifier when a small amount of water droplets may splash out of the steam outlet port 403 before the sealing weight 9 blocks the steam outlet port 403.

[0042] The edge of the valve seat 5 extends upward to form an inner blocking ring 52 surrounding the outer periphery of the steam outlet port 403, the edge of the cover 7 extends downward to form an outer blocking ring 71, the outer blocking ring 71 is arranged outside the inner blocking ring 52, and the outer blocking ring 71 and the inner blocking ring 52 are arranged in a vertically staggered manner, so that the steam forms a downward guide after passing through the steam exhaust gap 407, which can reduce the speed of the steam, avoid the steam from being discharged too fast out of the cover body 2, and improve the quality of the steam.

[0043] In addition, the outer periphery of the inner blocking ring 52 is circumferentially provided with a plurality of connecting holes 521, and the bottom surface of the cover 7 extends a plurality of support columns 72 corresponding to the connecting holes 521, the support columns 72 are arranged above the connecting holes 521, and the cover 7 is fastened and connected with the valve seat 5 by means of screws passing through the connecting holes 521 and the support columns 72.

[0044] The steam passage 201 is in the shape of a horn with a wide upper part and a narrow lower part, which helps to diffuse the steam in the air. The upper part of the steam passage 201 is provided with an inclined condensate return surface 202. The condensate formed in the steam passage 201 will drip on the condensate return surface 202 and flow to the center to flow into the return cavity 404. The lower part of the steam passage 201 is provided with a passage neck 203, which is arranged at the center of the steam passage 201.

[0045] The quick release structure includes a buckle convex part 21 arranged on the inner side of the passage neck 203 and a rotating buckle groove 408 arranged on the outer side of the valve seat assembly 4. The anti-toppling structure 3 can be detachably connected in the steam passage 201 through the circumferential rotation of the rotating buckle groove 408 and the buckle convex part 21. The anti-toppling structure 3 can be detached, which is convenient for the user to clean the anti-toppling structure and keep the inside and outside of the anti-toppling structure 3 clean.
