Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a heat insulation structure for humidifiers. Background Technology

[0002] Heated humidifiers, which increase ambient humidity by heating water to produce steam, are widely used in homes, medical care, and industrial humidification applications due to their stable mist output and high humidification efficiency. Their core working principle is as follows: water is heated to boiling point within the atomizing chamber of the humidifier base using a heating element. The resulting high-temperature steam is then discharged to the outside through the mist outlet. Simultaneously, the lower water chamber within the base stores cold water to be heated and continuously supplies water to the atomizing chamber through a connecting chamber.

[0003] During the operation of a heated humidifier, the atomizing chamber maintains a high temperature of around 100°C due to continuous heating, while the lower water chamber stores room-temperature cold water. If the high temperature of the atomizing chamber is directly transferred to the lower water chamber through the connecting chamber, the cold water in the lower water chamber will be rapidly heated. This not only wastes energy and reduces heating efficiency (requiring continuous replenishment of cold water to maintain boiling), but more seriously, when the high-temperature gas and liquid from the atomizing chamber are transferred to the lower water chamber, the air and cold water in the water tank will be affected, causing the liquid temperature and air pressure in the water tank to rise. The pressure difference between the water tank and the lower water chamber will force water from the water tank into the lower water chamber, causing the water level in the lower water chamber to rise and exceed the height of the connecting chamber, resulting in water from the lower water chamber flowing directly into the atomizing chamber. The atomizing chamber continuously heats the inflowing water, keeping the water levels in the lower water chamber consistent with those in the atomizing chamber, and the water in the lower water chamber also becomes a high-temperature liquid. Because the water tank is continuously heated, cold water is constantly discharged into the lower water chamber. Since the atomizing chamber cannot consume the excess water, hot water or high-temperature gas from the lower water chamber eventually overflows from the gap between the humidifier base and the water tank, posing a risk of scalding to users and presenting a significant safety hazard. Therefore, in heated humidifiers, the thermal insulation design between the atomizing chamber and the lower water chamber is a crucial element in ensuring the safe operation of the equipment.

[0004] In existing technologies, various structural solutions have emerged to address the heat insulation requirements of heating humidifiers. For example, some designs attempt to block the transfer of high temperature from the atomizing chamber to the connecting chamber and the lower water chamber by placing a heat insulation element at the interface between the mist outlet and the base cavity, and utilizing the internal flow channel of the element to form an insulated water path. One typical structure integrates the heat insulation element with the mist outlet as a single unit, with the heat insulation element directly inserted into the connecting chamber of the base. The heat insulation element fits snugly against the wall of the connecting chamber to form a closed flow channel, achieving heat insulation through water circulation.

[0005] However, this design has more prominent drawbacks in heated humidifiers: In actual production, the mist outlet and humidifier base are mostly manufactured using injection molding. Due to the thermal expansion and contraction characteristics of materials, mold precision, and fluctuations in injection molding parameters, the molded parts inevitably have dimensional errors and shape deviations. When the integrated insulation element is inserted into the connecting cavity, these errors prevent the mating surfaces from fitting completely tightly, resulting in tiny gaps. In the high-temperature environment of a heated humidifier, the high-temperature steam in the atomizing cavity will quickly seep into the connecting cavity through these gaps and further diffuse into the lower water cavity, causing the cold water in the lower water cavity to be continuously heated to a high temperature. At this time, not only will the excessively high water temperature in the lower water cavity exacerbate energy consumption, but the large accumulation of steam may also cause abnormal cavity pressure, eventually causing high-temperature water vapor to spray out from parts such as the water tank inlet, posing a serious safety threat to users. In addition, long-term high-temperature environments will also accelerate the aging and deformation of the mating surfaces of the insulation element and the connecting cavity, causing the gaps to gradually widen, further reducing the insulation effect, and seriously affecting the safety and reliability of the heated humidifier. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a heat insulation structure for a humidifier.

[0007] A heat insulation structure for a humidifier designed for this purpose includes a humidifier base, a soft rubber heat insulation component, and a mist outlet.

[0008] The humidifier base is provided with a water chamber, a connecting chamber and an atomizing chamber that are connected from left to right in sequence;

[0009] The mist outlet is disposed inside the atomizing chamber, and the bottom opening of the atomizing chamber is configured to communicate with the atomizing chamber.

[0010] The soft rubber heat insulation component is inserted into the communicating cavity, and the bottom wall and the front and rear side walls of the soft rubber heat insulation component are in contact with the cavity wall of the communicating cavity; the wall surface of the soft rubber heat insulation component facing the mist outlet is in contact with the outer wall of the mist outlet.

[0011] The soft rubber heat insulation component is provided with a connecting channel and an inlet and an outlet that are connected to the connecting channel. The inlet is connected to the lower water chamber, and the outlet is connected to the atomizing chamber.

[0012] Preferably, the bottom surface of the connecting cavity is flush with the bottom surface of the atomizing cavity, and the bottom surface of the connecting cavity is recessed downward relative to the bottom surface of the drain cavity.

[0013] Preferably, the vertical height of the water outlet is lower than the vertical height of the bottom surface of the lower water chamber.

[0014] Preferably, multiple connecting channels are provided, and a connecting port is provided between two adjacent connecting channels to connect them. The connecting channel near the water inlet is connected to the water inlet, and the connecting channel near the water outlet is connected to the water outlet.

[0015] Preferably, the soft rubber heat insulation component is provided with a positioning hole, and the humidifier base is provided with a positioning post that can be movably inserted into the positioning hole.

[0016] Preferably, the mist outlet is provided with an extension that extends above the soft rubber heat insulation component.

[0017] This utility model addresses the heat insulation needs of heating humidifiers. By employing a design that tightly integrates soft rubber insulation components with the humidifier base and mist outlet, it significantly improves the sealing and reliability of the insulation structure. Specific beneficial effects are as follows:

[0018] The soft rubber insulation component is made of elastic soft rubber material. Its bottom wall and front and rear side walls fit tightly against the wall of the connecting cavity, and the wall facing the mist outlet fits seamlessly against the outer wall of the mist outlet. This design utilizes the elasticity of the soft rubber to compensate for manufacturing errors and assembly gaps between the humidifier base (injection molded part) and the mist outlet. Even if there are dimensional deviations or geometric tolerances, the soft rubber material can still fill the gaps through its own deformation, effectively blocking the penetration of high-temperature steam in the atomization chamber into the lower water chamber through the connecting cavity, thus fundamentally avoiding the safety hazards of abnormal water temperature rise in the lower water chamber and water vapor splashing.

[0019] The internal connecting channels of the soft rubber insulation component independently form a water flow channel between the lower water chamber and the atomizing chamber. This ensures a stable supply of cold water from the lower water chamber to the atomizing chamber while reducing heat transfer from the high temperature of the atomizing chamber to the cold water in the connecting channels due to the insulation properties of the soft rubber material. Compared to traditional integrated rigid insulation components, the soft rubber insulation component can more effectively block heat conduction, reduce preheating loss of cold water in the lower water chamber, and improve the energy utilization efficiency of heating humidifiers.

[0020] The soft rubber material has excellent temperature resistance and anti-aging properties, and can adapt to the high-temperature environment (close to 100℃) of the atomizing chamber of heated humidifiers. At the same time, its elastic deformation characteristics can alleviate the thermal expansion and contraction stress caused by temperature changes in the base and mist outlet, reduce rigid wear between components, extend the service life of the heat insulation structure and the whole machine, and improve the stability and reliability of equipment operation.

[0036] See Figures 1-7 A heat insulation structure for a humidifier includes a humidifier base 10, a soft rubber heat insulation component 20, and a mist outlet 30. The humidifier base 10 is provided with a water outlet chamber 110, a connecting chamber 120, and an atomizing chamber 130 connected sequentially from left to right. The mist outlet 30 is disposed within the atomizing chamber 130, and the bottom opening of the atomizing chamber 130 is connected to the atomizing chamber 130. The soft rubber heat insulation component 20 is inserted into the connecting chamber 120. The bottom wall and front and rear side walls of the 0 are all in contact with the cavity wall of the connecting cavity 120; the wall of the soft rubber heat insulation component 20 facing the mist outlet 30 is in contact with the outer wall of the mist outlet 30; the soft rubber heat insulation component 20 is provided with a connecting flow channel 220 and an inlet 210 and an outlet 200 that are connected to the connecting flow channel 220. The inlet 210 is connected to the lower water cavity 110, and the outlet 200 is connected to the atomizing cavity 130.

[0037] The working principle of this utility model is as follows:

[0038] When the heating humidifier is running, the cold water to be heated stored in the lower water chamber 110 enters the connecting channel 220 through the inlet 210 of the soft rubber heat insulation component 20, and flows into the atomizing chamber 130 from the outlet 200 after being guided by the channel. The heating element in the atomizing chamber 130 heats the incoming cold water to a boiling state, and the generated high-temperature steam is discharged to the external environment through the mist outlet 30 set in the atomizing chamber 130, thus completing the humidification process.

[0039] During this process, the soft rubber insulation component 20 achieves heat insulation and sealing through a multi-layer bonding structure: its bottom wall and front and rear side walls are tightly bonded to the cavity wall of the connecting cavity 120, while the wall facing the mist outlet 30 is seamlessly bonded to the outer wall of the mist outlet 30. Due to the elastic deformation capability of the soft rubber material, it can compensate for the manufacturing errors of the humidifier base 10 (injection molded part) and the mist outlet 30 through its own deformation, completely blocking the penetration path of high-temperature steam in the atomizing cavity 130 to the connecting cavity 120 and the lower water cavity 110, and preventing high-temperature steam from bypassing the connecting flow channel 220 to directly heat the cold water in the lower water cavity 110.

[0040] On the other hand, the material properties of the soft rubber heat insulation component 20 have good heat insulation performance, which can reduce the high temperature of the atomizing chamber 130 from being conducted to the cold water in the connecting channel 220 through the chamber wall, ensuring that the cold water entering the atomizing chamber 130 maintains a low initial temperature, which not only improves heating efficiency, but also avoids the risk of water vapor splashing caused by abnormal temperature rise in the lower water chamber 110, thus achieving safe and stable humidification operation.

[0041] In this invention, the soft rubber heat insulation component 20 is made of silicone. The silicone material, with its excellent elasticity, allows for a tight fit between the cavity wall and the outer wall of the mist outlet, compensating for manufacturing errors to eliminate gaps and prevent high-temperature steam leakage. Simultaneously, silicone possesses excellent heat insulation and temperature resistance, enabling it to adapt to the high-temperature environment of the atomization chamber, enhancing the heat insulation effect and ensuring safe operation of the equipment.

[0042] See Figures 2 to 4 The bottom surface of the connecting cavity 120 is flush with the bottom surface of the atomizing cavity 130, and the bottom surface of the connecting cavity 120 is recessed downward relative to the bottom surface of the drain cavity 110. This flush alignment and recessed position ensures smooth connection between the soft rubber insulation component's flow channel and the atomizing cavity. Simultaneously, the height difference guides water from the drain cavity into the atomizing cavity naturally, improving the stability of the water flow.

[0043] See Figure 2The vertical height of the water outlet 200 is lower than the vertical height of the bottom surface of the lower water chamber 110. This lower height allows for the use of water level difference to create natural water pressure, ensuring that cold water in the lower water chamber can automatically and smoothly flow into the atomizing chamber through the connecting channel. This guarantees a continuous and stable water supply without the need for an additional power unit, simplifying the structure and improving reliability.

[0044] See Figures 5 to 7 Multiple connecting channels 220 are provided, and adjacent connecting channels 220 are connected to each other by connecting ports 230. The connecting channel 220 near the water inlet 210 is connected to the water inlet 210, and the connecting channel 220 near the water outlet 200 is connected to the water outlet 200. Multiple connecting channels 220 are interconnected through connecting ports 230 to form a multi-segment water flow path. This design increases the flow time of cold water in the channels, enhances the contact with the soft rubber insulation component 20, and improves the insulation effect; it also ensures smooth water flow, ensuring that cold water is stably delivered from the water inlet 210 to the water outlet 200, meeting the water supply requirements of the atomizing chamber 130.

[0045] Specifically, the two adjacent connecting ports 230 are staggered. This extends the flow path of water within the soft rubber insulation channel, slows down the water flow, increases the contact time between cold water and the soft rubber insulation, and further reduces the heat absorbed by the cold water during transportation by utilizing the insulation properties of the soft rubber. At the same time, it reduces the risk of high temperature in the atomization chamber being directly conducted to the lower water chamber through the channel, enhances the insulation effect, and ensures stable water temperature in the lower water chamber.

[0046] See Figure 2 The soft rubber heat insulation component 20 is provided with a positioning hole 240, and the humidifier base 10 is provided with a positioning post 140 that is movably inserted into the positioning hole 240. The positioning post 140 is inserted into the positioning hole 240, which can quickly position the soft rubber heat insulation component 20 in the connecting cavity 120, ensuring that it is precisely fitted with the connecting cavity 120 and the mist outlet 30, ensuring the sealing and heat insulation effect, and facilitating assembly.

[0047] See Figure 2 and Figure 3 The mist outlet 30 is provided with an extension 310 extending above the soft rubber heat insulation component 20. The extension of the mist outlet extending above the soft rubber heat insulation component can further prevent the high-temperature steam from the atomizing chamber from diffusing upwards into the connecting chamber, forming a double barrier with the sealing structure of the soft rubber heat insulation component, strengthening the heat insulation protection of the lower water chamber and reducing the risk of high-temperature leakage.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
