Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a hot mist humidifier. Background Technology

[0002] Heated humidifiers are favored by users during dry and cold seasons because they provide a comfortable and warm mist. Currently, a mainstream solution for achieving the warm mist effect is to install a PTC heating element inside the atomizing chamber. Its working principle is as follows: after the PTC is energized, it directly and continuously heats the water stored in the chamber, and then the heated water is atomized and sprayed out through ultrasonic waves or other atomizing devices, thus achieving the purpose of outputting warm mist.

[0003] However, this technical solution has significant inherent drawbacks: severe scale formation. During the continuous heating of water by the PTC heating element, the surface of the element and the surrounding water are at high temperatures, easily causing dissolved minerals such as calcium and magnesium to precipitate and adhere, forming stubborn scale. This scale accumulates rapidly on the PTC surface, not only covering the heating surface and reducing thermal efficiency and increasing energy consumption, but also being hard and extremely difficult to clean thoroughly. The risk of sealing failure and leakage is high; the continuous accumulation of scale poses a serious threat to the sealing structure of the atomizing chamber, especially the PTC installation area. These factors combined significantly increase the risk of poor sealing or even failure of the atomizing chamber at the PTC heating element installation site, ultimately leading to internal or external water leakage, causing safety hazards (such as electrical short circuits) and equipment damage.

[0004] Therefore, while existing PTC direct-heating water atomization solutions achieve a warm mist effect, the accompanying severe scale buildup and resulting high risk of leakage have become key bottlenecks restricting product reliability, user experience, and lifespan. Therefore, there is a need to design a humidifier hot mist structure that achieves a warm mist effect while effectively reducing scale buildup on the heating element and avoiding the risk of leakage.

[0024] Example Reference Figures 1 to 4The present invention proposes a hot mist humidifier, comprising: a base 10, a water tank 20, an atomizing component 30, a water discharge control component 40, a blower component 50, and a heating element 60; The base 10 is provided with an atomizing groove 11 and a working chamber 12 for placing electronic components; a water tank 20 is installed on the base 10 and covers the top of the atomizing groove 11; the water tank 20 is provided with a mist guide tube 21; an atomizing component 30 is installed on the atomizing groove 11 and located below the mist guide tube 21; a mist outlet is provided on the top of the water tank 20; the water tank 20 is provided with a water outlet 22 facing the atomizing groove 11; a water outlet control component 40 is provided at the water outlet 22 and controls the opening and closing of the water outlet 22 according to the water level in the atomizing groove 11. A blower-mixing chamber 70 is provided below the mist guide tube 21; the blower-mixing chamber 70 is located above the atomizing assembly 30 and is connected to the atomizing slot 11 and the mist guide tube 21; the blower assembly 50 includes a blower channel 51 and a blower 52; the blower channel 51 extends upward from the working chamber 12 to the blower-mixing chamber 70, and the air outlet faces the blower-mixing chamber 70; the heating element 60 is disposed in the blower channel 51, and the blower 52 can blow air towards the blower channel 51.

[0025] The core improvement of this invention lies in placing the heating element 60 within the airflow channel 51, rather than directly immersing it in the water of the atomizing tank 11. The heating element 60 only heats the air flowing within the airflow channel 51, completely avoiding direct contact with water. This eliminates the conditions for calcium and magnesium ions to precipitate and adhere to the surface of the heating element 60 due to high-temperature heating of the water, forming stubborn scale, and significantly reduces the generation and accumulation of scale on the core heating component. It solves the key problems of reduced heating efficiency, increased energy consumption, and shortened component lifespan caused by scale buildup in existing technologies. The heating element 60 is completely located within the relatively dry airflow channel 51 and working chamber 12, eliminating the risk of leakage caused by scale buildup damaging the seal or by cleaning scale damaging the seals.

[0026] In this embodiment, a blower-mist mixing cylinder 80 is disposed above the base 10; the blower-mist mixing cylinder 80 is positioned between the atomizing tank 11 and the mist guide cylinder 21; the blower-mist mixing cylinder 80, the lower surface of the water tank 20, and the upper surface of the base 10 together form a blower-mist mixing chamber 70. By providing an independent blower-mist mixing cylinder 80, together with the water tank 20 and the base 10, a well-defined blower-mist mixing chamber 70 is formed. This dedicated chamber provides optimized space for the full and uniform mixing of hot air and mist, ensuring the output quality and temperature stability of the warm mist.

[0027] Specifically, a mist-mixing connecting wall 13 is provided above the base 10, and the lower side of the blower mist-mixing cylinder 80 is detachably clipped to the mist-mixing connecting wall 13. As a component through which water vapor passes, the blower mist-mixing cylinder 80 may condense water droplets or have trace amounts of water stains adhering to its interior after long-term use. The detachable design allows users to easily remove it for cleaning, effectively preventing mold growth, ensuring hygienic mist output, and improving product maintainability and user experience.

[0028] In this embodiment, the blower-mixing mist cylinder 80 divides the atomizing tank 11 into an atomizing working tank 111 and an atomizing water storage tank 112. The atomizing working tank 111 is located below the blower-mixing mist chamber 70, and the atomizing component 30 is located inside the atomizing working tank 111. The atomizing water storage tank 112 is located outside the blower-mixing mist cylinder 80. Physically separating the atomizing working tank 111, where the atomizing component 30 is located, from the surrounding atomizing water storage tank 112 can reduce the direct impact of water level fluctuations in the storage tank on the atomizing core area (working tank), providing a more stable and calm working environment for the atomizing component 30, which helps to improve atomization efficiency and mist volume stability. The smaller working tank also accelerates the heating effect of the hot air on the water mist.

[0029] In this embodiment, the blower mist mixing cylinder 80 is provided with a water passage 81 connecting the atomizing working tank 111 and the atomizing water storage tank 112; a disinfection structure 14 is provided inside the water passage 81. The water passage 81 ensures that the atomizing working tank 111 can continuously receive water from the atomizing water storage tank 112. The disinfection structure 14 (such as an ultraviolet UV lamp, an antibacterial material filter, etc.) installed inside the passage can disinfect the flowing water in real time, inhibiting the spread of bacteria and microorganisms with the water mist from the source, significantly improving the hygiene level of the product and the health protection of users.

[0030] In this embodiment, a sound-absorbing baffle plate 82 is provided in the middle of the blower-mixing chamber 80. The sound-absorbing baffle plate 82 is horizontally arranged in the middle of the blower-mixing chamber 70, above the atomizing component 30. A central air guide port 83 is provided in the middle of the sound-absorbing baffle plate 82, forming a ring-shaped plate structure. Several sound-absorbing holes are formed on the ring plate of the sound-absorbing baffle plate 82. The sound-absorbing baffle plate 82 and the sound-absorbing holes on it together constitute an acoustic impedance structure. When the high-frequency sound waves and airflow noise generated by the atomizing component 30 propagate upward, they will pass through this structure. In this process, the sound waves are reflected, interfered with, and absorbed, thereby effectively attenuating the outward propagating noise, making the humidifier operate more quietly and improving the user experience.

[0031] Preferably, the sound-absorbing baffle plate 82 is inclined and arranged in a trumpet-shaped structure. The inclined trumpet-shaped structure not only retains the sound-absorbing function, but also plays a better role in guiding the rising mist and water flow, preventing them from accumulating on the baffle plate. At the same time, this special geometry helps the condensed water droplets to flow back smoothly.

[0032] In this embodiment, an extension ramp 15 is provided on one side of the atomizing working tank 111, extending obliquely to the air outlet of the blower channel 51. The extension ramp 15 allows hot air to be delivered more smoothly to the working tank area to mix with water mist; and, when the hot air coming out of the blower channel 51 encounters the relatively cool cavity wall, condensation may occur. The extension ramp 15 can smoothly guide this condensation back into the atomizing working tank 111, preventing condensation from accumulating in the blower mixing chamber 70 or near the air outlet, thereby preventing bacterial growth or interference with normal operation that may be caused by water accumulation.

[0033] In this embodiment, an air outlet cover 53 is provided at the air outlet end of the blower channel 51. The air outlet cover 53 is hinged to the air outlet end of the blower channel 51 and includes a hinge part 531, a cover plate 532, and a counterweight part 533. When the water tank 20 is installed on the base 10, the cover plate 532 can be moved and the air outlet end can be opened by abutting against the area of ​​the cover plate 532 away from the air outlet end. When the water tank 20 is lifted, the counterweight part 533 can cause the cover plate 532 to flip and close the air outlet end. When the water tank 20 is lifted (such as when adding water or moving the machine), the counterweight part 533 drives the cover plate 532 to automatically close the air outlet, effectively preventing dust, small insects, and other foreign objects from entering the blower channel 51 and the machine interior through the air outlet, keeping the air duct and heating element 60 clean, and improving the hygiene and long-term reliability of the product.

[0034] In this embodiment, the blower assembly 50 includes a detachable and assembleable fireproof protective box 54; the blower 52 and the heating element 60 are built into the fireproof protective box 54; the fireproof protective box 54 is equipped with a temperature control switch 55 and a temperature fuse 56. By housing the blower 52 and the heating element 60 within the independent fireproof protective box 54, physical isolation and a fire barrier are provided. The temperature control switch 55 and the fuse achieve a dual protection effect for the heating structure.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
