[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First embodiment: See Figures 1-11This steam humidifier includes a steam generating chamber 1 and a water storage chamber 2. The bottom of the steam generating chamber 1 is equipped with a heating element 21 for heating water and generating steam. The steam generating chamber 1 is set lower than the water storage chamber 2, so that water can only flow from the water storage chamber 2 into the steam generating chamber 1 in one direction. There is no need to install additional components such as water pumps between the steam generating chamber 1 and the water storage chamber 2, which optimizes the overall internal structure of the equipment and reduces production costs.

[0034] The steam generating chamber 1 is connected to a double-layer vacuum insulation cylinder 3. The inner wall of the steam generating chamber 1 is provided with a threaded groove 11, and the double-layer vacuum insulation cylinder 3 is provided with a threaded tooth 31 corresponding to the threaded groove 11. The threaded tooth 31 and the threaded groove 11 are connected and cooperate to form a water inlet gap 12 for water to flow from the water storage chamber 2 into the steam generating chamber 1. The water can only flow from the water storage chamber 2 into the steam generating chamber 1 in one direction. Moreover, the water inlet gap 12 can effectively control the water flow rate. As the water in the steam generating chamber 1 continues to evaporate, the heat can be effectively concentrated in the steam generating chamber 1, thereby improving the heating efficiency of the heating element 21. Under the same steam output demand, the power of the heating element 21 can be relatively reduced, making the equipment more energy-efficient.

[0035] The double-layer vacuum insulation cylinder 3 is installed and fixed on the inner wall of the steam generating chamber 1 by connecting and engaging the threaded teeth 31 and the threaded groove 11. The connection and engagement of the threaded teeth 31 and the threaded groove 11 can also achieve the effect of quick assembly and disassembly between the double-layer vacuum insulation cylinder 3 and the inner wall of the steam generating chamber 1.

[0036] Specifically, when the equipment is working, when the internal temperature of the steam generating chamber 1 is heated to 100℃, the water temperature in the water storage chamber 2 is only 40-45℃, and the overall heat insulation effect is good.

[0037] Furthermore, a limiting protrusion 32 is provided on the outer side of the double-layer vacuum insulation cylinder 3, which abuts against the upper periphery of the steam generating chamber 1 to improve the installation accuracy of the double-layer vacuum insulation cylinder 3 and the steam generating chamber 1.

[0038] The distance from the limiting protrusion 32 to the bottom of the double-layer vacuum insulation cylinder 3 is H1, and the distance of the threaded groove 11 extending vertically is H2, where H2 > H1. That is, the threaded groove 11 extends at least partially to below the bottom of the double-layer vacuum insulation cylinder 3, thereby guiding the liquid smoothly into the steam generating chamber 1.

[0039] Furthermore, several water inlet recesses 13 are distributed around the upper periphery of the steam generating chamber 1. The limiting protrusion 32 abuts against the upper periphery of the steam generating chamber 1 and forms a water receiving structure with the water inlet recesses 13. The water storage chamber 2 is connected to the water inlet gap 12 through the water inlet structure. After the limiting protrusion 32 abuts against the upper periphery of the steam generating chamber 1, the water flow can only enter the water inlet gap 12 through the preset water inlet recesses 13, which more effectively controls the water flow rate and allows the water flow to flow into the steam generating chamber 1 according to the preset flow rate.

[0040] Furthermore, the inner side of the double-layer vacuum insulation cylinder 3 is provided with an exhaust chamber 33, and the side wall of the double-layer vacuum insulation cylinder 3 is provided with an insulation layer 34 at the position between the exhaust chamber 33 and the water storage chamber 2. The double-layer vacuum insulation cylinder 3 can preferably be made of stainless steel. The insulation layer 34 is a vacuum chamber set in the side wall of the double-layer vacuum insulation cylinder 3, which can further insulate the steam inside the double-layer vacuum insulation cylinder 3 from the cold water in the water storage chamber 2.

[0041] Furthermore, the upper side of the double-layer vacuum insulation cylinder 3 is provided with an exhaust port 35 and a movable member 4 that can abut against and block the exhaust port 35. The movable member 4 is located below the exhaust port 35 and is connected to an elastic reset member 41 for pushing the movable member 4 to abut against the exhaust port 35 when the double-layer vacuum insulation cylinder 3 is tilted. When the double-layer vacuum insulation cylinder 3 is upright, the movable member 4 presses against the elastic reset member 41 and separates from the exhaust port 35, which can prevent hot water in the steam generating chamber 1 from flowing out when the equipment tilts, thus improving the safety of the equipment.

[0042] Furthermore, the upper side of the double-layer vacuum insulation cylinder 3 is connected to a detachable upper cover 42, and an exhaust port 35 is provided on the upper cover 42. The lower side of the upper cover 42 is connected to a detachable housing 43. The inner side of the housing 43 is hollowed out to form an exhaust chamber 33. The movable part 4 and the elastic reset part 41 are both provided in the exhaust chamber 33. The movable part 4 and the elastic reset part 41 can be pre-installed in the housing 43. The housing 43 is then installed and connected to the upper cover 42. Finally, the upper cover 42, the housing 43 and the double-layer vacuum insulation cylinder 3 form an integral module and are installed with the steam generating chamber 1 to improve the assembly efficiency of the equipment.

[0043] Furthermore, the upper cover 42 and the double-layer vacuum insulation cylinder 3 are detachably connected to each other through a threaded structure. The outer side of the housing 43 is provided with a limiting protrusion 431, and the upper cover 42 is provided with a limiting groove 421 corresponding to the limiting protrusion 431. The limiting protrusion 431 is connected and engaged with the limiting groove 421 by screwing to fix the housing 43 and the upper cover 42, thereby achieving a quick assembly and disassembly effect between the upper cover 42 and the double-layer vacuum insulation cylinder 3, and between the housing 43 and the upper cover 42.

[0044] Furthermore, the bottom of the housing 43 is provided with several circumferentially distributed air inlets 432. The inner side of the housing 43 is provided with limiting ribs 433 corresponding to the positions between adjacent air inlets 432. The outer wall of the movable part 4 abuts against the limiting ribs 433 to form an air outlet channel 434 between the movable part 4 and the inner wall of the housing 43. The air inlets 432 and the exhaust holes 35 are connected through the exhaust channel. The limiting ribs 433 can limit the movable part 4 so that the movable part 4 will not obstruct the airflow through the exhaust channel, ensuring that the gas can be discharged normally when the equipment is upright and working normally.

[0045] Furthermore, the upper cover 42 is provided with a pressure relief hole 422, which is connected to a sealing plug 44 that can be pushed away from the pressure relief hole 422 by gas. When the pressure inside the double-layer vacuum insulation cylinder 3 is greater than the friction between the sealing plug 44 and the pressure relief hole 422, the gas can push open the sealing plug 44 and be discharged outward through the pressure relief hole 422, thus avoiding excessive pressure inside the double-layer vacuum insulation cylinder 3 and potential safety hazards.

[0046] Furthermore, the upper side cover of the water storage chamber 2 is connected to a detachable face cover 5. The face cover 5 is provided with a clearance hole 51 corresponding to the double-layer vacuum insulation cylinder 3, which facilitates the user to add water to the water storage chamber 2.

[0047] Second embodiment: See Figure 12 , Figure 13 The difference between this embodiment and the first embodiment is that: the outer side of the housing 43 of this steam humidifier is provided with a soundproof cover 46, and the outer side of the soundproof cover 46 is provided with a steam inlet 461. The steam generating chamber 1 is connected to the air inlet 432 through the steam inlet 461. The bottom of the soundproof cover 46 is provided with a drain hole 462. The soundproof cover 46 can collect condensate water, so that the condensate water can be concentrated in the drain hole 462 and discharged. When the equipment is working, the noise generated by the boiling of water in the steam generating chamber 1 propagates upward. Under the action of the soundproof cover 46, the noise can be effectively isolated from the position of the housing 43 to the outside, thereby achieving the effect of noise reduction.

[0048] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0049] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
