Description

Technical Field

[0001] This application claims priority based on a Chinese utility model application filed on January 28, 2026 (application number: 2026201275495), and all the contents of that application are incorporated herein by reference.

[0002] The present invention relates to the technical field of humidifiers, and specifically, to the cold and heat dual-function atomization structure of humidifiers.

Background Art

[0003] With the improvement of people's quality of life, the adjustment of indoor air quality has been increasingly emphasized. As a key device for maintaining indoor humidity within a comfortable range, humidifiers are widely applied in various scenarios such as homes, offices, and factories. Humidifiers with both cold mist and warm mist output functions can adapt to different seasons and the usage needs of different people, such as cooling and humidifying with cold mist in summer and warming and humidifying with warm mist in winter, so they have become the mainstream of the market development direction.

[0004] Currently, the atomization structures of conventional cold and heat dual-function humidifiers mainly have the following technical defects, which have a profound impact on user experience and product competitiveness.

[0005] First, many products adopt the design of two tanks or independent cold and warm mist generation units, so the overall structure is complex, the volume is large, the heat insulation design between tanks or between cold and heat passages is incomplete, and heat conduction phenomena are likely to occur. For example, the heat of the warm water tank is conducted to the water storage tank, abnormally increasing the temperature of the equipment on the flow path, and long-term use may shorten the service life of the device. Second, in the prior art, all cold and heat dual-function atomizations adopt a structure that cools after heating and atomizing to achieve cold mist. Therefore, the atomization efficiency of cold mist is low, the spraying is slow, the heating energy consumption of warm mist is high, and it is difficult to achieve the energy-saving goal while considering the usage experience.

[0006] Based on the shortcomings of the conventional technology described above, there is a need to provide a dual-function cold and hot atomization structure that is compact, has high thermal insulation, low noise, is easy to switch, and is energy-saving and efficient, in order to fill the gaps in the conventional technology. [Overview of the Initiative]

[0007] The objective of this invention is to provide a dual-function atomizing structure for a humidifier that combines heating and cooling functions, in order to solve the technical problems that exist in the prior art.

[0008] To achieve the above objective, this invention employs the following technical means.

[0009] The humidifier has a dual-function cooling and cooling atomization structure including a water tank. The inside of the water tank is divided into two parts: a water replenishment tank and an atomization tank. An ultrasonic atomizer is provided at the bottom of the atomization tank. A tank lid is provided at the top of the water tank. A heat transfer tube is provided at the top of the tank lid. The heat transfer tube communicates with the atomization tank. An electric heating device is provided on the outer surface of the heat transfer tube. An exhaust fan is provided at the part of the top of the tank lid corresponding to the atomization tank. The exhaust fan blows air into the atomization tank. The ultrasonic atomizer atomizes the water into a cold mist, which is then blown into the heat transfer tube by the exhaust fan. The cold mist is heated by the electric heating device and then discharged from the spray nozzle at the tip of the heat transfer tube.

[0010] Furthermore, the water tank includes a tank body, and a flow guide tube with a C-shaped cross-section is provided at the bottom of the inner wall of the tank body, the top of the flow guide tube communicates with the bottom of the heat transfer tube, and flow guide plates are fixedly connected to both of the two vertical sides of the flow guide tube, and one side of the flow guide plate is fixedly connected to the inner corner side of the tank body, and the flow guide tube and the two flow guide plates divide the inside of the tank body into the water supply tank and the atomization tank.

[0011] Furthermore, the ultrasonic atomizer is permanently attached to the bottom of the flow guide tube.

[0012] Furthermore, an automatic water replenishment device is provided on one of the flow guide plates, and water in the water replenishment tank is supplied to the atomization tank through the automatic water replenishment device.

[0013] Furthermore, an insulating cover is installed on the outside of the electric heating device, and insulating material is filled between the electric heating device and the inner wall of the insulating cover.

[0014] Furthermore, the temperature of the electric heating device is adjustable.

[0015] The beneficial effects of this invention are as follows: 1. Achieves atomization through a dual-function cooling and heating system, with adjustable electric heating temperature to suit different usage needs. 2. The cold mist is heated to a warm mist, and there is no boiling water design, making it less likely to cause burns even if it tips over, thus providing high safety. 3. It does not require boiling water, only heating the mist, resulting in high thermal energy utilization, energy saving, and environmental friendliness. 4. The C-shaped flow guide tube and flow guide plate optimize airflow, improve spray velocity, and have a simple and rational structure. 5. An automatic water replenishment system is installed for ease of use, and insulation covers and materials further ensure safety during use. 6. It is highly adaptable and compatible with most commercially available atomizing devices such as humidifiers and facial steamers. [Brief explanation of the drawing]

[0017] To more clearly explain embodiments of the present invention or technical means in the prior art, the present invention will be briefly described below with reference to the drawings and descriptions of embodiments or the prior art. Clearly, the structural descriptions in the following drawings represent only a few embodiments of the present invention, and those skilled in the art can derive other drawings from these drawings without any creative effort. These descriptions of embodiments are intended to aid in the understanding of the present invention, but are not intended to limit it.

[0018] Embodiments: As shown in Figures 1-3, this embodiment provides a dual-function cold and hot atomization structure for a humidifier including a water tank 5. The inside of the water tank 5 is divided into two parts: a water replenishment tank 5 and an atomization tank. An ultrasonic atomizer 6 is provided at the bottom of the atomization tank, a tank lid 504 is provided at the top of the water tank 5, a heat transfer tube 1 is provided at the top of the tank lid 504, the heat transfer tube 1 is in communication with the atomization tank, an electric heating device 2 is provided on the outer surface of the heat transfer tube 1, and an exhaust fan 4 is provided at the part of the top of the tank lid 504 corresponding to the atomization tank. The exhaust fan 4 blows air into the atomization tank, the ultrasonic atomizer 6 atomizes water into cold mist and blows it into the heat transfer tube 1 by the exhaust fan 4, the cold mist is heated by the electric heating device 2 and then discharged from the spray port at the tip of the heat transfer tube 1.

[0019] Specifically, the water in the water tank 5 is atomized into cold mist by the ultrasonic atomizer 6, then diffused into the atomization tank, and cold air is blown into the atomization tank by the exhaust fan 4, causing the cold mist to be blown into the bottom of the heat transfer tube 1, where it is heated by the electric heating device 2 located on the outer surface of the heat transfer tube 1. The blown-in cold mist is rapidly heated by the thermal energy passing through the heat transfer tube 1, and finally, warm mist is ejected from the nozzle. The temperature of the electric heating device 2 is adjustable, and the user's need for temperature control can be met by adjusting the heating temperature according to the user's needs.

[0020] As described above, this structure is compatible with the configuration of most atomizing devices currently on the market, such as humidifiers and facial steamers.

[0021] This atomization structure is different from the conventional commercially available warm mist atomization structure mainly by boiling water. This device directly heats the generated cold mist. When the structure accidentally collapses, it manufactures mist from cold water, so it will not scald the user, the temperature of the spray port will not become too high, and scalding can be effectively prevented. Also, this device is energy-saving and environmentally friendly. There is no need to boil water for warm mist, and the electric heating device 2 is only used when mist needs to be heated. Thermal energy is fully utilized without waste, and the structure is simple and reasonable.

[0022] At the bottom of the inner wall of the tank body 501 of the water tank 5, a flow guide cylinder 502 with a C-shaped cross-section is provided. The top of the flow guide cylinder 502 communicates with the bottom of the heat transfer cylinder. On both vertical sides of the flow guide cylinder 502, flow guide plates 503 are fixedly connected. One side of the flow guide plate 503 is fixedly connected to the inner corner side of the tank body 501. The flow guide cylinder 502 and the two flow guide plates 503 divide the inside of the tank body 501 into a water replenishing tank 5 and an atomization tank. The ultrasonic atomizer 6 is fixedly mounted at the bottom of the flow guide cylinder 502. An automatic water replenishing device 7 is provided on one of the flow guide plates 503. The water in the water replenishing tank 5 is replenished into the atomization tank through the automatic water replenishing device 7.

[0023] Specifically, as shown in Figure 3, a triangular prism-shaped atomization tank is surrounded by the flow guide cylinder 502, the two flow guide plates 503 and a part of the tank body 501. The exhaust fan 4 blows air to its wide area, and the generated mist is quickly gathered at a narrow location, sequentially improving the transmission speed of the mist and helping to improve the spraying speed of the device.

[0024] An insulating cover 3 is covered outside the electric heating device 2, and an insulating material is filled between the electric heating device 2 and the inner wall of the insulating cover 3, thereby further improving the heat insulation performance of the structure and making this structure safer and more reliable during the use process.

[0025] The above describes only preferred embodiments of the present invention and does not limit the scope of protection. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should all be included within the scope of protection.
