[0003] Traditional heating scheme usually adopts overall heating mode, i.e. heating element directly acts on all liquid in liquid storage container. However, due to large liquid volume, heating time is long, and heat is easily lost through container wall and liquid surface, leading to energy consumption rising. This problem is particularly obvious in large-capacity commercial or industrial applications, and the problem of insufficient boiling heating efficiency is more prominent. SUMMARY

[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0026] To solve the problems in the background art, the utility model provides a liquid boiling structure for humidifier, which comprises:

[0027] a liquid storage container 1;

[0028] a heating structure 2 arranged at the bottom of the liquid storage container 1; and

[0029] a partitioning structure 3 arranged inside the liquid storage container 1 to divide the inside of the liquid storage container 1 into a first cavity 31 and a second cavity 32, and having a communication assembly 4 for maintaining dynamic balance of liquid levels inside and outside the partitioning structure 3, the partitioning structure having a larger cross-sectional diameter at the bottom region than at the upper region, thereby forming a flared structure;

[0030] The heating structure 2 is completely immersed in the liquid inside the partitioning structure 3, which can limit the range of heat transfer and make the liquid in the first cavity 31 preferentially heated and rapidly boiled.

[0031] In combination with the drawings Figs. 1 to 3 In the present embodiment, the liquid storage container 1 is the basic component for storing liquid, which is usually made of transparent or translucent high-temperature-resistant material (such as glass or food-grade plastic) to facilitate the user to observe the water level change. The bottom of the container is designed to be flat to ensure that the heating structure 2 can be stably installed and fully contacted with the liquid. The capacity of the liquid storage container 1 can be flexibly adjusted according to the purpose of the humidifier (for home, commercial or industrial use), and water level graduation lines can be provided on the outer wall to directly display the liquid level height, thereby effectively avoiding the risk of dry burning. The heating structure 2 is fixed to the bottom of the liquid storage container 1, which usually adopts a high-power electric heating tube or a PTC ceramic heating element, and the surface is coated with a corrosion-resistant and heat-conductive coating (such as silicon nitride or aluminum oxide) to improve the heat conduction efficiency and prolong the service life.

[0032] The partitioning structure 3 is the core component of the boiling structure in the present application, which is usually made of high-temperature-resistant plastic or metal material. In the present embodiment, a water separation cover is preferably used, which is a cylindrical cover coaxially arranged with the liquid storage container 1. In addition, the partitioning structure 3 can also be composed of multiple isolation plates. This structure divides the inside of the liquid storage container 1 into the first cavity 31 (inside) and the second cavity 32 (outside) through physical isolation. The communication assembly 4 is arranged on the partitioning structure 3, which can be a communication hole, a communication pipeline, etc., for realizing the liquid communication and liquid level balance between the two cavities. The heating structure 2 is located below the first cavity 31 and is completely immersed in the liquid to ensure more efficient heat transfer.

[0033] Specifically, after adding liquid into the liquid storage container 1, the liquid flows into the internal part of the partitioning structure 3 through the communication assembly 4, and the liquid levels inside and outside maintain dynamic balance under the action of gravity and atmospheric pressure. When heating is started, the liquid in the first cavity 31 directly contacts the heat-generating tube, rapidly heats up in the local area of the first cavity 31 and generates bubbles, forming a convection cycle of heat rising and cold descending. Due to the presence of the water distribution cover, the heated liquid only generates convection in the first cavity 31, so that the liquid in the first cavity 31 will reach boiling before the external liquid. The partitioning structure 3 limits the range of heat transfer, so that the first cavity 31 becomes a local high-temperature area, thereby making the liquid in the first cavity 31 reach the boiling point preferentially, significantly shortening the overall heating time. In the case of constant container volume, the design of the application can effectively improve the heating efficiency of the humidifier.

[0034] In the embodiment, the partitioning structure 3 is a water distribution cover, the bottom of which is designed as a flared structure, the cross-sectional diameter of which is increased by 1.2 to 2 times compared with the upper region, forming a geometric shape of wide bottom and narrow top. The bottom of the flared structure closely adheres to the heating structure 2 at the bottom of the liquid storage container 1, thereby increasing the contact area with the liquid and improving the heat conduction efficiency, so that the heat energy of the heat-generating tube can be more efficiently transmitted to the surrounding liquid.

[0035] In a possible implementation, the communication assembly 4 comprises:

[0036] a first communication hole 41, which is arranged at the top end of the partitioning structure 3;

[0037] a second communication hole 42, which is arranged at the connection transition section between the bottom region and the upper region of the partitioning structure 3.

[0038] In combination with the above description Fig. 3As shown, in this embodiment, the communication assembly 4 is composed of a first communication hole 41 and a second communication hole 42, aiming to optimize the liquid level balance and heat convection efficiency. The first communication hole 41 is opened at the top end of the partition isolation structure 3, serving as the core channel for the static balance of the liquid level, maintaining the consistency of the liquid level inside and outside by atmospheric pressure, and ensuring the free flow of the liquid in the initial stage. The second communication hole 42 is located at the connection transition section between the bottom region and the upper region of the partition isolation structure 3, specifically distributed at the starting end of the flared structure (i.e., the transition region where the cross-sectional diameter changes from small to large). It can simultaneously act on the bidirectional flow of hot liquid rising and cold liquid supplementing: after the heated liquid absorbs heat at the wide bottom region of the flared structure, it naturally rises along the flared slope due to the decrease in density, while the external cold liquid quickly flows in from the transition section side wall through the second communication hole 42, forming a continuous convection cycle. The opening position of the transition section is optimized by fluid mechanics, which can disperse local thermal stress, reduce the deposition of scale in the flared region, and prevent the sudden drop of the liquid level in the partition isolation structure 3 caused by evaporation, reducing the risk of dry burning. The two holes work together: on the one hand, the top opening maintains the basic liquid level balance, and on the other hand, the transition section opening strengthens the dynamic heat exchange, significantly improving the local heating efficiency, making the liquid in the first cavity 31 preferentially boil.

[0039] In one possible implementation, the top side wall of the partition isolation structure 3 is also provided with a plurality of diffusion holes 5, which are uniformly distributed circumferentially, for accelerating the upward diffusion of the heated liquid.

[0040] In combination with reference Fig. 3 As shown, in this embodiment, the top side wall of the partition isolation structure 3 is also provided with a plurality of diffusion holes 5, which are uniformly distributed circumferentially. These diffusion holes 5 are located in the upper region of the partition isolation structure 3, adjacent to the dynamic balance region of the liquid level in the first cavity 31. When the liquid in the first cavity 31 is heated, the hot liquid naturally rises to the top region due to the decrease in density, and quickly diffuses to the second cavity 32 through the diffusion holes 5, forming a stable upward flow; at the same time, the external cold liquid is supplemented to the first cavity 31 through the bottom and transition section communication holes, forming a closed loop convection path of "hot rising and cold descending". The uniform distribution design of the diffusion holes 5 can reduce the flow resistance, avoid local vortex or heat accumulation, and evenly transfer the heat to the upper space of the liquid storage container 1, accelerating the generation of steam.

[0041] In a possible implementation, the liquid storage container 1 is a glass water tank for facilitating observation of the internal liquid level and heating state. Specifically, the liquid storage container 1 of the embodiment is made of transparent glass material, constituting a glass water tank, and the outer wall of which is marked with water level scale lines, facilitating intuitive monitoring of the liquid level and heating state by the user. The glass material is resistant to high temperature, corrosion and stable in chemical properties, and can be in contact with high-temperature liquid for a long time without deformation or release of harmful substances. The bottom of the water tank is flat and closely attached to the heating structure 2, ensuring efficient heat conduction; the smooth design of the side wall reduces the adhesion of scale, and the transparent property displays the internal convection in real time, so that the user can quickly identify insufficient water or abnormal heating, significantly improving the use safety and maintenance convenience.

[0042] In a possible implementation, the heating structure 2 includes a heating disc surface 21 provided at the bottom of the first cavity 31 and a heating tube 22. Specifically, the heating structure 2 of the embodiment includes a heating disc surface 21 provided at the bottom of the first cavity 31 and a heating tube 22 integrated in the inside thereof. The heating disc surface 21 is made of aluminum alloy, and the heating tube 22 is embedded in the inside of the disc surface and closely attached by heat-conducting silicone grease, which is made of nickel-chromium alloy material. After being powered on, the heat generated by the heating tube 22 is quickly and uniformly transmitted to the liquid through the disc surface, accelerating the local liquid warming, and at the same time, the edge of the disc surface is sealingly connected with the bottom of the partitioning structure 3, preventing the heat from spreading to the second cavity 32, so that the liquid in the first cavity 31 quickly reaches boiling.
