[0020] The present invention will be further described below in conjunction with the attached drawings and embodiments.

[0021] As illustrated in FIGS. 1 to 7, a heated humidifier comprising a humidifying body (1) and a cover (2), wherein the cover (2) is openably connected to the humidifying body (1) to surround a steam generating chamber (101), and the cover (2) is equipped with a steam passage (201) and a fall prevention structure (3), wherein the fall prevention structure (3) comprises a valve seat assembly (4), a quick-detachable structure is provided between the valve seat assembly (4) and the cover (2), and the fall prevention structure (3) is detachably connected within the steam passage (201) through the quick-detachable structure.

[0022] The anti-tipping structure (3) can be detached from the cover, allowing the user to conveniently clean the anti-tipping structure, maintain cleanliness inside and outside the anti-tipping structure, and make installation and maintenance convenient.

[0023] Additionally, a mounting chamber (401) is provided within the valve seat assembly (4), and a sealing weight (9) is movably installed within the mounting chamber (401). A steam intake port (402) is opened in the valve seat assembly (4) corresponding to the upright portion of the mounting chamber (401) to connect the steam generating chamber (101) and the mounting chamber (401). A steam exhaust port (403) is opened in the valve seat assembly (4) corresponding to the lowered portion of the mounting chamber (401). When the humidifier falls over, the sealing weight (9) slides from the upright portion to the lowered portion to block the steam exhaust port (403).

[0024] After the humidifier falls over unexpectedly, the sealing weight (9) blocks the steam exhaust port (403) by gravity when it falls over, preventing water inside the steam generating chamber (101) from leaking out and improving the safety of the humidifier.

[0025] In this embodiment, the mounting chamber (401) and the sealing weight (9) have a truncated cone structure with a wide upper section and a narrow lower section, and the shape of the sealing weight (9) matches the shape of the lower part of the mounting chamber (401). When the sealing weight (9) is in the upright section of the mounting chamber (401), the shapes match, so the mounting chamber (401) can position the sealing weight (9) to avoid shaking of the sealing weight (9). Since they have a truncated cone structure, the operation of the sealing weight (9) can still be driven even if the humidifier falls in any direction. Additionally, due to the truncated cone structure, when the humidifier falls in a horizontal state, the side wall of the mounting chamber (401) is installed in an inclined shape, thereby ensuring that the sealing weight (9) can slide from the upright section to the lying section of the mounting chamber (401).

[0026] Additionally, the sealing weight (9) may be a metal block with a truncated cone structure or a metal block with a truncated cone structure, and an elastic silica gel plate may be connected to the sealing cross-section, or it may be an elastic silica gel block with a truncated cone structure, and a metal block with a certain weight may be placed inside the elastic silica gel block to improve the sealing effect of the steam exhaust port (403) through the elastic silica gel plate or elastic silica gel block.

[0027] The above steam intake port (402) is opened on the side wall of the mounting chamber (401) and is installed spaced apart from the sealing weight (9), and the above steam exhaust port (403) is opened on the top wall of the mounting chamber (401) and is installed concentrically with the mounting chamber (401). By opening the steam intake port (402) on the side wall, the steam intake port (402) is not blocked even when the sealing weight (9) is in the upright portion of the mounting chamber (401), and by opening the steam exhaust port (403) on the central axis line portion, when the sealing weight (9) slides to the lying portion at any angle, the sealing cross-section of the sealing weight (9) is ensured to block the steam exhaust port (403) at the eccentric portion.

[0028] Several support convex ribs (41) are evenly distributed in the circumferential direction on the wall of the mounting chamber (401), and several support convex ribs (41) are installed extending along the depth direction of the mounting chamber (401). When the humidifier falls over, the sealing weight (9) slides on at least two support convex ribs (41) and is installed spaced apart from the steam intake port (402) through the support convex ribs (41).

[0029] In addition, the sealing weight (9) and the steam intake port (402) can be installed apart by the support convex rib (41) described above, and the surface of the support convex rib (41) has an arc-shaped structure, so that when the sealing weight (9) slides from the upright part to the lying part, the friction between the two is reduced, allowing the sealing weight (9) to slide more smoothly, and guides the sealing weight (9), and after the sealing weight (9) blocks the steam exhaust port (403), the sealing weight (9) is caught between the two support convex ribs (41), thereby preventing the sealing weight (9) from shaking left and right and ensuring the blocking effect of the steam exhaust port (403).

[0030] The above valve seat assembly (4) includes a valve seat (5) and a valve cover (6), wherein a circumferential mounting cross-section (502) is provided at the top of the valve seat (5), and the valve cover (6) and the valve seat (5) are connected by fastening and the mounting cross-section (502) is sealed and pressed to form a sealed joint surface between the valve seat (5) and the valve cover (6). By ensuring that the valve cover (6) and the valve seat (5) can be sealed and come into contact with each other through a fastening connection in which the connecting boss and the connecting hole are aligned, a sealing ring structure is not required, thereby shortening the mounting process, increasing production efficiency, and reducing production costs.

[0031] A mounting groove (501) is installed in the bottom portion of the valve seat (5), and the valve cover (6) and the mounting groove (501) are enclosed to form a mounting chamber (401) between them, and the sealing weight (9) is positioned within the mounting chamber (401), and the steam exhaust port (403) is opened in the valve cover (6), and the valve seat assembly (4) is assembled through the combination of the valve seat (5) and the valve cover (6), making it convenient to seat the sealing weight (9) within the mounting groove (501), and the sealing weight (9) is positioned using the valve cover (6).

[0032] The above valve seat assembly (4) is further provided with a reflux chamber (404) separated from the mounting chamber (401), wherein a condensate inlet (405) communicating with the steam passage (201) is opened on the side wall of the reflux chamber (404), and a condensate reflux port (406) communicating with the steam generation chamber (101) is opened on the bottom wall of the reflux chamber (404), and a one-way valve structure capable of opening or sealing the condensate reflux port (406) is connected to the valve seat assembly (4), and during the humidification process, high-temperature steam forms condensate within the steam passage (201), then initially flows to the anti-tipping structure (3), and then flows into the steam generation chamber (101) via the condensate inlet (405), the reflux chamber (404), and the condensate reflux port (406) for reuse.

[0033] The above-mentioned one-way valve structure includes an elastic valve membrane (8), wherein a snap-fit ​​boss (81) extends axially in the elastic valve membrane (8), and a valve membrane bracket (51) is provided within the condensate return port (406), and a snap-fit ​​hole (511) is opened in the valve membrane bracket (51), and through the snap-fit ​​fitting of the snap-fit ​​boss (81) and the snap-fit ​​hole (511), the elastic valve membrane (8) is sealed and comes into contact with the lower part of the condensate return port (406).

[0034] The one-way valve structure of the said structure can prevent the condensate return port (406) from frequently opening during the heating process and affecting the heating efficiency of the steam generation chamber (101), and also, when the humidifier falls over, the elastic valve membrane (8) can seal the condensate return port (406).

[0035] During use, after a certain amount of condensate has accumulated in the reflux chamber (404), if the received pressure is greater than the elastic part energy of the elastic valve membrane (8), the condensate pushes the elastic valve membrane (8) to open, thereby opening the condensate reflux port (406) and flowing into the steam generation chamber (101). After the condensate in the reflux chamber (404) is reduced, the elastic valve membrane (8) is reset using the elastic part energy, and the condensate reflux port (406) is sealed again.

[0036] The above valve seat assembly (4) further includes a shielding cover (7), wherein the shielding cover (7) is fastened and connected to the top of the valve seat (5), and the diameter of the shielding cover (7) is larger than the diameter of the valve seat (5), and the two are installed spaced apart vertically to form a circumferential steam exhaust gap (407), and the shielding cover (7) forms an arc-shaped structure with a high center and a low periphery, and on the one hand, the shielding cover (7) prevents steam discharged from the steam intake port (402) from rising and then being directly discharged through the cover (2), and by exhausting to the periphery using the steam exhaust gap (407), it helps to disperse the steam into the air, and when the humidifier is suddenly tipped over, a small amount of water droplets can be ejected from the steam exhaust port (403) before the sealing weight (9) blocks the steam exhaust port (403). Therefore, on the other hand, the shielding cover (7) can improve the safety of the humidifier by blocking the ejected water droplets.

[0037] An inner retainer (52) installed around the outer circumference of the steam exhaust port (403) extends upward from the edge of the valve seat (5), and an outer retainer (71) extends downward from the edge of the cover (7). The outer retainer (71) is installed on the outside of the inner retainer (52), and the outer retainer (71) and the inner retainer (52) are installed in an up-and-down offset manner. By installing the outer retainer (71) in an up-and-down offset manner with respect to the inner retainer (52), a downward guide is formed after the steam passes through the steam exhaust gap (407), thereby reducing the speed of the steam and preventing the steam from being rapidly discharged out of the cover (2), thereby improving the mass of the steam.

[0038] Additionally, on the outer side of the inner retainer (52), a plurality of connection holes (521) are provided in the circumferential direction, and on the bottom surface of the cover (7), a plurality of support columns (72) are extended corresponding to the connection holes (521). The support columns (72) are installed on the upper part of the connection holes (521), and the cover (7) and the valve seat (5) are fastened and connected by passing through the connection holes (521) and the support columns (72) via screws.

[0039] The steam passage (201) has a trumpet-shaped structure with a wide upper section and a narrow lower section, and the steam passage (201) of the above shape helps to diffuse steam into the air. The upper segment is provided with a condensate recirculation surface (202), and the condensate formed within the steam passage (201) falls onto the condensate recirculation surface (202), merges into the center, and flows into the recirculation chamber (404). The lower segment of the steam passage (201) is provided with a passage neck portion (203), and the passage neck portion (203) is located at the center of the steam passage (201).

[0040] The above-mentioned quick-release structure includes a snap-fit ​​convex portion (21) installed on the inner side of the passage neck portion (203) and a rotating snap-fit ​​groove (408) installed on the outer side of the valve seat assembly (4), wherein the anti-tipping structure (3) is detachably connected within the steam passage (201) through circumferential rotational alignment of the rotating snap-fit ​​groove (408) and the snap-fit ​​convex portion (21), and the anti-tipping structure (3) is detachable so that the user can conveniently clean the anti-tipping structure, maintain cleanliness of the inside and outside of the anti-tipping structure (3), and convenient mounting and maintenance.
