Technical Field

[0001] The present invention relates to the field of humidifiers, and more particularly to a hot mist sterilizing humidifier. Background Art

[0002] Since humidifiers need to store water for a long time and atomize it for humidification operations, bacteria are extremely likely to breed after long-term use. If not cleaned in time, the bacteria will be discharged into the indoor air, directly affecting physical health. To avoid the above problems, humidifiers that can self-sterilize are favored by the majority of consumers.

[0003] Most of the existing humidifiers use heating sterilization for their sterilization function. Its structure is to add a heating function to the water tank to increase the water temperature and generate hot mist for the purpose of sterilization and disinfection; due to the high water temperature, the timer of the above structure affects the normal atomization operation of the atomization sheet in the atomization component, reducing the service life of the atomization sheet; at the same time, due to the high temperature of the water tank, it will conduct to the outer shell of the humidifier, directly affecting the user's experience, and even the safety of use.

[0004] Therefore, how to design and manufacture a humidifier that can achieve cooling without affecting the service life of the atomization sheet, the user experience and the safety of use on the structure of hot mist sterilization is one of the important technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0005] To solve the above problems, the present invention discloses a technical solution of a hot mist sterilizing humidifier, which includes a water tank and a base for assembling the water tank. The base has a water tank on the side facing the water tank. The bottom of the water tank has a water outlet, which faces the water tank. Among them:

[0021] Most existing humidifiers use heating for sterilization. Their structure is to add a heating function to the water tank to increase the water temperature and generate hot fog for the purpose of sterilization and disinfection. Due to the high water temperature, the timer of the above structure affects the normal atomization operation of the atomization sheet in the atomization component and reduces the service life of the atomization sheet. At the same time, the high temperature of the water tank will be conducted to the outer shell of the humidifier, directly affecting the user experience and even the use safety.

[0022] In view of the above technical problems, through analysis of the causes and continuous research, the inventor has found a technical solution for a hot mist sterilizing humidifier, which includes a water tank and a base for assembling the water tank. The base has a water trough on the side facing the water tank. The bottom of the water tank has a water outlet, which faces the water trough. Specifically:

[0023] The water trough is divided into a hot steam chamber and an atomization chamber by a heat conductor. The hot steam chamber and the atomization chamber are two relatively isolated and adjacent chambers, and the water outlet is correspondingly arranged opposite to the atomization chamber;

[0024] A hot steam water level detector is arranged in the hot steam chamber.

[0025] In the above technical solution, the water trough is divided into an independent hot steam chamber and an atomization chamber by a heat conductor, and the hot steam chamber and the atomization chamber are not connected. Thus, the heat generated or accumulated by heating the hot steam chamber can be conducted to the atomization chamber through the heat conductor, and the water in the atomization chamber is used for self-cooling to block the heat and prevent it from being transmitted to the outer shell of the humidifier, effectively solving the technical problems existing in the prior art.

[0026] The following will give a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0027] Embodiment:

[0028] As Figures 1 to 2 shown, a hot mist sterilizing humidifier includes a base 1 and a water tank 2. The water tank 2 is a container with a water filling port and a water outlet, and a water outlet valve for controlling water discharge and the amount of water discharged is installed in the water outlet. An atomization assembly is installed in the base 1, and a water trough 11 is opened on its top surface. The water trough 11 can receive the water discharged from the water outlet and cooperate with the atomization assembly for atomization humidification.

[0029] As Figure 3 shown, the water trough 11 is divided into a hot steam chamber 1-1 and an atomization chamber 1-2 by a heat conductor 3. The hot steam chamber 1-1 and the atomization chamber 1-2 are adjacent and not connected. Both the hot steam chamber 1-1 and the atomization chamber 1-2 are chambers. The heat conductor 3 can be in the form of a sheet or a plate, etc., which can conduct heat and divide the water trough;

[0030] Preferably, the heat conductor is a closed-loop annular body, which divides the water trough 11 into the hot steam chamber 1-1 and the atomization chamber 1-2. The atomization chamber 1-2 surrounds the outside of the hot steam chamber 1-1, and the water outlet is correspondingly arranged opposite to the atomization chamber 1-2. The atomization assembly is installed in the atomization chamber 1-2;

[0031] Specifically: The heat conductor 3 is a quadrilateral frame, which is fixed to the bottom surface of the water tank 11 to form the heat evaporation chamber 1-1. The atomization chamber 1-2 is arranged around the periphery of the heat evaporation chamber 1-1. The heat evaporation chamber 1-1 is cooled in the atomization chamber 1-2 through the heat conductor 3, effectively blocking the heat and preventing the humidifier from being affected by heat and unable to work properly, etc.; In this embodiment, the heat conductor 3 is a square ring body, so that the heat evaporation chamber 1-1 is a square cavity, and the remaining cavities of the water tank 11 form the atomization chamber 1-2;

[0032] It should be noted that: The height of any side wall of the heat conductor 3 is less than the depth of the water tank 11.

[0033] As Figures 1 to 3 shown, the heat evaporation chamber 1-1 is an independent chamber equipped with a heating element, and the atomization chamber 1-2 is an atomization element for realizing atomization. A heat evaporation water level detector 1-11 and an atomization water level detector 1-21 are respectively arranged in the heat evaporation chamber 1-1 and the atomization chamber 1-2. The heat evaporation water level detector 1-11 and the atomization water level detector 1-21 are both connected to the controller. The controller can be a PLC controller, etc., mainly to effectively monitor and detect the water level height of the heat evaporation chamber 1-1 and the atomization chamber 1-2, and at the same time cooperate with the controller to drive or control whether the water inlet valve is opened for water inlet. This technology and the corresponding functions have been commonly used in this field and will not be elaborated here.

[0034] As Figures 1 to 3 shown, a partition cover 4 is also provided. The partition cover is installed at the bottom of the water tank. When the water tank 2 is installed on the base 1, the partition cover 4 is located above the heat evaporation chamber 1-1 or / and the atomization chamber 1-2. While ensuring the effective heat conduction and cooling of the heat conductor 3, it can also effectively guide and gather the hot mist;

[0035] Specifically: The partition cover 4 is the bottom plate of the water tank 2. It is installed at the bottom of the water tank 2 in a split or integral manner and can be installed on the base 1. The water outlet is opened on the partition cover 4;

[0036] More specifically: The partition cover 4 is a plate body, which bulges towards the water tank 2 to form a convex platform part 41. A part of the convex platform part 41 continues to protrude towards the water tank 2 and is close to the top of the water tank 2 to form a columnar jacking part 42, forming a guiding structure that can effectively gather and guide the hot mist; The partition cover 4 is also provided with a blocking extension wall 43. The blocking extension wall 43 is formed by the partition cover 4 extending towards the water tank 11. The blocking extension wall 43 is located on the side of the partition cover 4 close to the base 1;

[0037] In this embodiment, the isolation cover 4 is disposed above the thermal evaporation chamber 1-1 and the atomization chamber 1-2. The thermal evaporation chamber 1-1 is arranged corresponding to the lifting portion of the isolation cover 4, and the atomization chamber 1-2 is arranged corresponding to the boss portion 41 of the isolation cover 4. The barrier extension wall 43 is integrally connected to the isolation cover 4. The barrier extension wall 43 includes a connected thermal evaporation section and an atomization section, and the thermal evaporation section is adapted to the thermal evaporation chamber 1-1.

[0038] As Figures 1 to 3 shown, the working principle of the hot mist sterilization humidifier is as follows:

[0039] When the thermal evaporation chamber 1-1 starts heating and reaches the vaporization temperature, heat is accumulated in the thermal evaporation chamber 1-1. The heat is conducted to the atomization chamber 1-2 through the heat conductor and is absorbed by the water in the atomization chamber 1-2, thus preventing excessive heat from being conducted to the outer shell of the humidifier.

[0040] The water level in the thermal evaporation chamber 1-1 drops with vaporization and drops to trigger the detection of the thermal evaporation water level 1-11, and the water inlet valve starts to let water in. The water inlet valve lets water into the atomization chamber 1-2, and the water level in the atomization chamber 1-2 rises and covers the heat conductor 3 around the hot mist chamber, so as to let water flow into the thermal evaporation chamber 1-1 and continuously guide the water until the water level in the thermal evaporation chamber 1-1 reaches the set value, at which time the water inlet valve stops letting water in.

[0041] It should be noted that the highest water level in the thermal evaporation chamber 1-1 is lower than the height of any side wall of the heat conductor 3.

[0042] Although the present invention is disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the scope of the claims of the present invention.
