Description

Technical Field

[0001] The utility model relates to a humidifier, in particular to a heat preservation and heat insulation structure of a heating atomizing humidifier. Background Art

[0002] A warm mist humidifier can heat the water in the water tank and atomize it. The atomized mist has a certain temperature, which can make the human body feel comfortable. For example, the patent document with the authorization announcement number CN221923790U discloses a hot mist humidifier, which includes a water tank and a main unit installed on the top of the water tank. The bottom of the main unit is connected to an insulation barrel, which extends downward into the water tank. A heating device and an atomizing device extend from the bottom of the main unit into the insulation barrel. The insulation barrel can reduce the amount of water that needs to be heated, thereby shortening the time to heat to the preset temperature, which is conducive to reducing energy consumption. However, this structure requires the entire main unit and insulation barrel to be dismantled when cleaning the insulation barrel. Not only is it difficult to disassemble and assemble, but it is also difficult to clean later.

[0029] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 8 A thermal insulation structure of a heated atomizing humidifier includes a water tank 1 and a thermal insulation component 2. The inner side of the bottom surface of the water tank 1 is provided with an upwardly protruding cofferdam portion 11, and an ultrasonic atomizer 12 and a heater 13 are installed in the cofferdam portion 11. The thermal insulation component 2 is connected to the cofferdam portion 11 in a detachable manner. In this way, when cleaning in the later stage, the thermal insulation component 2 can be disassembled separately without disassembling the heater 13 and the ultrasonic atomizer 12. On the one hand, it reduces the difficulty of assembly and facilitates disassembly and assembly. On the other hand, it reduces the movement of electronic components, thereby avoiding damage caused by human factors. In addition, the bottom of the thermal insulation component 2 and the cofferdam portion 11 form a closed heating atomization chamber 21. The cofferdam portion 11 or the thermal insulation component 2 is provided with a water inlet 22 connecting the inside and outside of the heating atomization chamber 21. The water inlet 22 is installed with a one-way valve 23 to prevent the water inside the heating atomization chamber 21 from flowing outward, thereby preventing the hot water in the heating atomization chamber 21 from mixing with the cold water in the water tank 1. It has a heat preservation effect, thereby reducing the energy consumption of the humidifier. The thermal insulation component 2 is provided with a mist outlet channel 24 corresponding to the ultrasonic atomizer 12, and the side wall of the thermal insulation component 2 is provided with a first air inlet 25 connected to the mist outlet channel 24.

[0031] The heater 13 is used to heat the water body, and the ultrasonic atomizer 12 is used to make mist. The shell of the heater 13 is a heat-conducting material, such as stainless steel, and a PTC heating plate is provided in the heater 13, which can quickly heat the water body. During operation, the heater 11 heats, heats or keeps the water body warm. In this embodiment, the heater 13 and the ultrasonic atomizer 12 are fixedly mounted on the lower side of the bottom surface of the water tank 1, and the bottom surface of the water tank 1 is provided with a heating port and an atomizing port for exposing the heater 13 and the ultrasonic atomizer 12, wherein the heater 13 and the ultrasonic atomizer 12 are fixedly connected to the water tank 1 by screws, and a waterproof sealing structure, such as a silicone seal or waterproof glue, is also installed between the heater 13 and the ultrasonic atomizer 12 and the water tank 1 to improve waterproofness.

[0032] As a further improvement of the present invention, the thermal insulation assembly 2 includes a lower thermal insulation component 3, an upper thermal insulation component 4, and a mist outlet component 5 connected in sequence from bottom to top. The lower side of the lower thermal insulation component 3 is provided with a connecting portion 31 adapted to the shape of the cofferdam portion 11. After assembly, the bottom of the connecting portion 31 rests on the inner side of the bottom surface of the water tank 1, and the outer wall of the connecting portion 31 and the inner wall of the cofferdam portion 11 are interference fit. In this embodiment, there is no buckle or threaded fixing structure between the connecting portion 31 and the cofferdam portion 11. The two are fixed by an interference fit, which is not only convenient for assembly but also has a certain degree of sealing.

[0033] The lower insulating member 3 is provided with a lower semi-insulated groove 32 on its upper side, and the upper insulating member 4 is provided with an upper semi-insulated groove 41 on its lower side. When the lower and upper insulating members 3 and 4 are fixedly connected, a sealed insulating chamber 26 is formed between the lower semi-insulated groove 32 and the upper semi-insulated groove 41. The insulating chamber 26 isolates the cold water in the inner cavity of the water tank 1 from the hot water in the heating atomization chamber 21, effectively preventing heat loss from the heated liquid. This provides thermal insulation and further reduces the energy consumption of the humidifier.

[0034] The lower end of the lower thermal insulation member 3 is open, and the upper end is provided with a lower mist outlet 33; the lower end of the upper thermal insulation member 4 is provided with a middle mist inlet 42 connected to the lower mist outlet 33, and the upper end is provided with a middle mist outlet 43; the lower end of the mist outlet member 5 is provided with an upper mist inlet 51 connected to the middle mist outlet 43, and the upper end is provided with an upper mist outlet 52. The upper mist outlet 52 can be connected to a mist outlet duct to facilitate the discharge of warm mist. The lower mist outlet 33, the middle mist inlet 42, the middle mist outlet 43, the upper mist inlet 51, and the upper mist outlet 52 constitute the mist outlet channel 24. In this embodiment, the upper end of the upper thermal insulation member 4 is provided with an annular side wall 44 extending vertically upward, and the annular side wall 44 is provided with a plurality of second air inlets 45. The side wall of the mist outlet member 5 is provided with a plurality of first air inlets 25. The first air inlet 25 and the second air inlet 45 are used to introduce external air into the heating atomization chamber 21 to circulate the air and improve the mist outlet efficiency. In addition, the first air inlet 25 and the second air inlet 45 are arranged in a staggered manner. Since the ultrasonic atomizer 12 will vibrate during operation, some hot water will splash out. The staggered arrangement of the first air inlet 25 and the second air inlet 45 can prevent hot water from splashing out from the first air inlet 25.

[0035] A plurality of downward vertical snap arms 53 are provided at the edge of the upper mist inlet 51, and snap hooks 54 are provided at the ends of the snap arms 53. After assembly, the snap arms 53 are inserted into the middle mist outlet 43, and the snap hooks 54 are snapped onto the inner surface of the middle mist outlet 43, and the assembly structure is simple.

[0036] As a further improvement of the present invention, an annular transverse portion 55 extending laterally outward is provided at the edge of the upper mist outlet 52, and an annular vertical portion 56 extending vertically downward is provided at the end of the annular transverse portion 55. After assembly, the upper end of the annular side wall 44 abuts against the bottom of the annular transverse portion 55, and the inner wall of the annular vertical portion 56 and the outer wall of the annular side wall 44 are interference fit, and the assembly structure is simple. In this embodiment, an annular extension portion 57 extending upward and outward is provided at the end of the annular transverse portion 55, and the upper mist outlet 52 is higher than the annular transverse portion 55. The annular extension portion 57 is higher than the upper mist outlet 52, and an annular water storage tank is formed between the annular transverse portion 55, the annular extension portion 57 and the edge of the upper mist outlet 52. During operation, a mist outlet duct 6 for discharging mist is installed on the top of the annular extension portion 57, refer to Figure 9 The dotted arrow in the figure indicates the flow direction of the splashed hot water. The lower end of the mist outlet conduit 6 is provided with an annular connecting portion 61 that matches the shape of the annular extension 57. After assembly, the annular connecting portion 61 is inserted into the annular water storage tank, and the outer wall of the annular connecting portion 61 and the inner wall of the annular extension 57 are in contact with each other. Due to the vibration of the ultrasonic atomizer 12, a small amount of hot water will splash out of the upper mist outlet 52. The splashed hot water flows along the inner wall of the mist outlet conduit 6 to the annular connecting portion 61, and then flows into the annular water storage tank. When the water level in the annular water storage tank is higher than the upper mist outlet 52, the water in the annular water storage tank naturally flows into the heated atomization chamber 21, which serves to recover the hot water, reduce hot water loss, and lower the energy consumption of the humidifier.

[0037] One side of the lower thermal insulation component 3 is provided with a water inlet channel 27 connecting the inside and outside of the heating atomizing chamber 21, and the water inlet 22 is provided in the water inlet channel 27. The inner side of the top surface of the water inlet channel 27 is provided with a downwardly protruding limit portion 28. After assembly, one end of the limit portion 28 is against the front end surface of the one-way valve 23, playing a one-way blocking role. Specifically, when the water level of the heating atomizing chamber 21 is higher than the height of the one-way valve 23, the pressure applied by the hot water in the heating atomizing chamber 21 to the one-way valve 23 is resisted by the limit portion 28; and when the water level of the heating atomizing chamber 21 is lower than the height of the one-way valve 23, the pressure applied by the hot water in the heating atomizing chamber 21 to the one-way valve 27 is less than the pressure applied by the cold water in the water tank 1 to the one-way valve 23, and the rear end surface of the one-way valve 23 is not blocked, so that it is pushed open by the cold water in the water tank 1, thereby achieving the automatic water adding effect. In this embodiment, the one-way valve 23 includes a baffle 231 and a hanging ear 232 located at the upper end of the baffle 231 and extending laterally outward to both sides. The top of the water inlet channel 27 is provided with a downwardly recessed groove 29, and the hanging ear 232 is installed on the groove 29; the outer wall of the upper thermal insulation component 4 is provided with a downward vertically extending limit plate 46 corresponding to the groove 29. After assembly, the lower end of the limit plate 46 rests on the top of the one-way valve 23 to prevent the one-way valve 23 from falling, and the assembly structure is simple.
