Description

Technical Field

[0001] This application relates to the field of humidification equipment technology, such as an integrated vaporizer and humidification device. Background Technology

[0002] With the continuous development of the biomedical and environmental testing fields, the requirements for the precision of internal humidification control in equipment such as incubators, constant temperature and humidity chambers, and environmental test chambers are becoming increasingly stringent. In order to provide a stable humidity environment for test samples, the humidification system needs to have high-precision quantitative vaporization capabilities.

[0003] In related technologies, existing humidification devices typically employ a pump-driven quantitative vaporization humidification system. The conventional approach involves pumping liquid water into a heating copper tube with a narrow inner diameter for vaporization, and then transporting the generated water vapor over a long distance and spraying it into the interior of the chamber through a long external air delivery hose.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: In related technologies, existing vaporization humidification systems are limited by the structure of slender vaporization pipes with uniform diameter and long-distance gas delivery hoses. This results in insufficiently vaporized liquid water and secondary condensation during long pipeline transportation, which can be directly pushed into the chamber by steam pressure, causing water to spray from the humidification port and thus disrupting the temperature and humidity stability of the incubation environment inside the chamber.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

The heating assembly is located outside the vaporization section and is thermally coupled to the vaporization section. The flow cross-sectional area of ​​the fluid channel in the vaporization section is larger than that of the water inlet and also larger than that of the air outlet.

[0009] In some embodiments, the integrated vaporizer further includes a heat insulation structure. The heat insulation structure is disposed between the outlet and the mounting wall of the external device to form a thermal barrier, thereby preventing heat conduction from the vaporizer body to the mounting wall.

[0010] In some embodiments, the vaporizer body is placed vertically and the inlet is connected to the bottom of the vaporization section; a bottom liquid storage space with a cross-sectional area larger than the inlet is formed at the bottom of the vaporization section, and the bottom liquid storage space is configured to receive and collect the incompletely vaporized liquid water that falls back due to gravity.

[0013] In some embodiments, a removable structure is provided on the sidewall of the vaporizer body corresponding to the vaporization section, and the removable structure is configured to be opened from the outside to expose the interior of the vaporization section.

[0014] This disclosure also provides a humidification device for humidifying a room to be humidified. The humidification device includes a pump body and the aforementioned integrated vaporizer.

[0015] In some embodiments, when the integrated vaporizer includes a heat insulation structure, a fixing connector is provided on the outer peripheral surface of the heat insulation structure; the vaporizer body passes through the heat insulation structure and the fixing connector and is fixed to the perforation of the chamber to be humidified.

[0016] In some embodiments, the humidification device further includes a humidity sensor and a controller.

The vaporizer body has an internal fluid channel, which is sequentially divided into an interconnected water inlet, a vaporization section, a buffer section, and an air outlet along the fluid flow direction. The heating component is located outside the vaporization section and is thermally coupled to it. The cross-sectional area of ​​the fluid channel in the vaporization section is larger than that of the water inlet and the air outlet. This variable-diameter design of the fluid channel allows incompletely vaporized liquid water to settle and be retained at the bottom of the vaporization section, preventing it from being pushed into the chamber by pressure. Simultaneously, the buffer section facilitates internal cooling and allows for direct, hose-free fixing of the vaporizer body to the humidification chamber. This design effectively solves the problem of liquid water and condensate easily spraying into the chamber and disrupting the stability of the internal environment due to thin-tube vaporization and long-tube delivery.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] This disclosure provides an integrated vaporizer 14 and a humidification device, which effectively solves the technical problem in the related art that liquid water and condensate are easily sprayed into the chamber due to vaporization through slender pipes and delivery through long flexible hoses, thus disrupting the stability of the chamber's environment.

[0031] like Figures 1 to 6 As shown, this embodiment of the present disclosure provides an integrated vaporizer 14, including: a vaporizer body 21 and a heating assembly 22. A fluid channel is formed inside the vaporizer body 21, and along the fluid flow direction, the fluid channel is sequentially divided into an inlet 211, a vaporization section 212, a buffer section 213, and an outlet 214 that are interconnected. The heating assembly 22 is disposed outside the vaporization section 212, and the heating assembly 22 is thermally coupled to the vaporization section 212. The flow cross-sectional area of ​​the fluid channel in the vaporization section 212 is larger than the flow cross-sectional area of ​​the inlet 211 and larger than the flow cross-sectional area of ​​the outlet 214.

[0032] Specifically, the vaporizer body 21 has an integrally formed fluid channel inside. Along the natural flow direction of the fluid, the fluid channel is sequentially divided into an interconnected inlet 211, a vaporization section 212, a buffer section 213, and an outlet 214, forming a complete continuous flow path. The heating component 22 is tightly fitted onto the outer surface of the vaporization section 212 corresponding to the vaporizer body 21 to achieve efficient thermal coupling between the heating component 22 and the vaporization section 212. To overcome the drawbacks of traditional thin-tube constant-diameter vaporization, the cross-sectional dimension of the vaporization section 212 is larger than the flow cross-sectional area of ​​the inlet 211 and also larger than the flow cross-sectional area of ​​the outlet 214. During fluid movement, external liquid water is first forced into the wide vaporization section 212 through the narrow inlet 211. At this time, the heating component 22 transfers heat energy across the wall of the vaporizer body 21 to the inner side of the vaporization section 212, forcing the liquid water to absorb heat, boil, and violently transform into water vapor. Phase change is accompanied by a rapid expansion of volume, which usually generates strong forward-propelling high pressure within a closed pipeline. However, when the vapor-liquid mixture enters the vaporization section 212, the fluid velocity decreases significantly due to the sudden expansion of the flow cross-section. The previously accumulated vapor expansion pressure is dispersed and released within the spacious vaporization section 212. This disrupts the kinetics of high-pressure steam carrying liquid water from the bottom forward, mechanically preventing the liquid water from being directly pushed into the outlet 214. Subsequently, the pure water vapor generated by vaporization flows smoothly through the buffer section 213 and merges into the outlet 214 for discharge. This design effectively solves the technical problem in related technologies where vaporization in slender pipelines and the transport of liquid water through long flexible hoses easily cause liquid water and condensate to spray into the chamber, disrupting the stability of the internal environment.

[0033] In the above embodiments, the thermal coupling between the heating component 22 and the vaporization section 212 can be achieved through various structural forms. In one example, the heating component 22 is constructed as an electric heating wire or electric heating strip, which is tightly attached to the outer wall of the vaporization section 212 by spiral winding or axial attachment, and fixed by thermally conductive adhesive or metal cable ties. The Joule heat generated by the heating component 22 after being energized is transferred to the tube wall of the vaporization section 212 through heat conduction at the contact interface, thereby heating the fluid inside the tube wall; in another example, the heating component 22 is constructed as a thick film heating layer, which is directly formed on the outer wall of the vaporization section 212 by screen printing or thermal spraying, forming an integrated structure with the vaporizer body 21. There is no air gap between the thick film heating layer and the wall of the vaporization section 212, resulting in low interfacial thermal resistance, fast thermal response, and no need for additional mechanical fasteners. In another example, the heating component 22 is constructed as a cast aluminum heating block with an embedded heating element. The inner cavity shape of the heating block is adapted to the outer contour of the vaporization section 212, and the two achieve surface contact through interference fit or bolt clamping. The cast aluminum heating block has a large heat capacity, providing a stable thermal environment for the vaporization section 212 and reducing temperature fluctuations caused by power fluctuations. It is understood that, regardless of the specific structural form, the thermal coupling between the heating component 22 and the vaporization section 212 aims to efficiently and uniformly transfer the heat generated by the heating component 22 to the fluid channels inside the vaporization section 212, ensuring that the liquid water entering the vaporization section 212 can quickly absorb sufficient latent heat of vaporization and undergo a complete phase change.

[0034] It should be noted that the cross-sectional shapes of the fluid channel in the vaporization section 212, the inlet 211, and the outlet 214 can be selected according to the actual manufacturing process and fluid dynamics requirements. When the cross-section of the fluid channel is constructed as a circle, the flow cross-sectional area of ​​the vaporization section 212 is larger than that of the inlet 211 and larger than that of the outlet 214, meaning that the diameter of the vaporization section 212 is larger than that of the inlet 211 and larger than that of the outlet 214. When the cross-section of the fluid channel is constructed as a non-circular shape, such as an ellipse, rectangle, or polygon, the flow cross-sectional area of ​​the vaporization section 212 is larger than that of the inlet 211 and larger than that of the outlet 214, meaning that the equivalent diameter of the vaporization section 212 is larger than that of the inlet 211 and larger than that of the outlet 214. In this embodiment of the disclosure, regardless of the geometry of the cross-section, as long as the flow cross-sectional area of ​​the vaporization section 212 is increased relative to the inlet 211 and the outlet 214, the technical effects of reduced flow velocity and dispersed steam expansion pressure when the fluid enters the vaporization section 212 can be achieved, thereby preventing liquid water from being pushed into the outlet 214 by pressure. Therefore, the specific examples described above in terms of diameter or equivalent diameter all fall within the protection scope covered by the increased flow cross-sectional area.

[0035] Optionally, the flow cross-sectional area between the vaporization section 212 and the buffer section 213 is configured to have a preset transition relationship, so as to further optimize the retention of liquid water and the return of condensate while ensuring the smooth passage of steam.

[0036] Specifically, the end of the vaporization section 212 connects to the beginning of the buffer section 213, and the cross-sectional area relationship between the two at the connection point can be set according to actual needs. In one example, the cross-sectional area at the beginning of the buffer section 213 is smaller than the cross-sectional area at the end of the vaporization section 212, causing a cross-sectional contraction in the transition area between the vaporization section 212 and the buffer section 213. This cross-sectional contraction helps the steam flow orderly towards the buffer section 213, reducing the stagnation and eddies of steam in the top region of the vaporization section 212. At the same time, the annular step or slope naturally formed at this cross-sectional contraction constitutes a flow guiding transition surface in a vertical installation posture. This transition surface can guide the condensate flowing back from the inner wall of the buffer section 213 smoothly into the vaporization section 212, preventing the condensate from accumulating at the connection gap or dripping to the center of the vaporization section 212 and being secondary entrained by the rising steam flow.

[0037] In some embodiments, the integrated vaporizer further includes a heat insulation structure 34. The heat insulation structure 23 is disposed between the air outlet 214 and the mounting wall of the external device to form a thermal barrier, thereby blocking heat conduction from the vaporizer body 21 to the mounting wall.

[0038] Specifically, the heat insulation structure 23 is annular and nested on the outer peripheral wall of the air outlet 214. The inner peripheral surface of the heat insulation structure 23 fits against the outer wall of the air outlet 214, while the outer peripheral surface abuts against the mounting wall of external equipment (e.g., the inner edge of the perforation in the inner liner of the housing). After assembly, the heat insulation structure 23 is clamped between the vaporizer body 21 and the mounting wall to cut off the direct heat conduction path from the high-temperature vaporization section 212 through the air outlet 214 to the mounting wall. Simultaneously, during assembly, the heat insulation structure 23 is subjected to compressive loads from both sides and undergoes elastic compression deformation. This deformation, on the one hand, fills the assembly gap between the outer wall of the air outlet 214 and the perforation in the mounting wall, providing a sealing effect and preventing water vapor or external air leakage along the interface; on the other hand, the rebound force generated by the deformation maintains continuous positive pressure between the heat insulation structure 23 and the side walls, ensuring a stable heat-blocking effect even under long-term operation and repeated thermal expansion and contraction.

[0039] In the above embodiments, the heat insulation structure 23 can be a split structure, for example, formed by two half-rings joined together by snap-fit, or directly constructed as a single ring, so as to facilitate radial installation or replacement without disassembling other parts of the vaporizer body 21. The heat insulation structure 23 can also be an integral structure, for example, constructed as a heat insulation layer directly formed on the outer wall of the outlet 214. This heat insulation layer can be integrated with the outer wall of the outlet 214 through a secondary injection molding process, thermal spraying process, or sintering process. The material of the heat insulation structure 23 can be a high-temperature resistant elastomer with low thermal conductivity, such as silicone rubber or fluororubber, to ensure that thermal softening or permanent deformation does not occur within the operating temperature range of the vaporization section 212.

[0040] In some practical applications, the thermal insulation structure 23 is specifically configured as a thermal insulation sleeve. The thermal insulation sleeve is sleeve-shaped and has a central hole extending axially. The inner diameter of the central hole matches the outer diameter of the air outlet 214, allowing the thermal insulation sleeve to fit tightly onto the outer peripheral wall of the air outlet 214. The axial length of the thermal insulation sleeve is not less than the length of the air outlet 214 exposed above the vaporizer body 21, ensuring that after assembly, the thermal insulation sleeve completely covers the entire area where contact may occur between the air outlet 214 and the external equipment mounting wall.

[0041] In some embodiments, the vaporizer body 21 is placed vertically, and the inlet 211 is connected to the bottom of the vaporization section 212; a bottom liquid storage space with a cross-sectional area larger than that of the inlet 211 is formed at the bottom of the vaporization section 212, and the bottom liquid storage space is configured to receive and collect the incompletely vaporized liquid water that falls back due to gravity.

[0042] Specifically, the vaporizer body 21 is placed vertically, with the inlet 211 directly opposite and connected to the bottom of the vaporization section 212. Based on the geometric feature of the abruptly expanded diameter of the vaporization section 212, a bottom liquid storage space with a cross-sectional area larger than the inlet 211 is naturally formed at the bottom of the vaporization section 212, immediately above the inlet 211. The heating component 22 is at least tightly wrapped around the outer wall of the vaporizer body 21 corresponding to this bottom liquid storage space, creating a localized high heat flux density envelope at the bottom of the vaporization section 212. When incompletely vaporized liquid droplets are pulled downwards by gravity, overcoming the drag force of the upward steam flow, these droplets eventually fall and converge within the bottom liquid storage space. Because the heating component 22 is wrapped around at least part of the periphery of this liquid storage space, the liquid water is forced to adhere tightly to the inner bottom wall of the vaporization section 212, which is at an extremely high temperature. At this point, the accumulated liquid water is forced to undergo high-frequency secondary heat absorption and violent boiling, and then transforms into high-temperature water vapor again, regaining upward fluid lift.

[0043] In some embodiments, the buffer section 213 is located between the vaporization section 212 and the outlet 214, and the buffer section 213 is configured to form a physical cooling transition zone between the high-temperature vaporization section 212 and the outlet 214.

[0044] Specifically, the buffer section 213 is integrally connected between the vaporization section 212 and the outlet 214. The outer wall of the vaporizer body 21 corresponding to the buffer section 213 is exposed or unheated, meaning that the outer wall of the buffer section 213 is not covered by the heating component 22, thus configuring the buffer section 213 as a cold channel isolated from the heat source. When pure ultra-high temperature steam flows from the boiling vaporization section 212 across the fluid boundary into the buffer section 213, the temperature of the buffer section 213 wall is significantly lower than the internal steam temperature because the wall is not continuously heated by the external heating component 22. During the smooth movement of the steam along the buffer section 213 channel towards the outlet 214, the sensible heat contained within the steam begins to dissipate naturally through heat conduction and radiation to the relatively low temperature of the buffer section 213 wall. This spontaneous heat exchange feedback based on the channel surface area transforms the buffer section 213 into a dynamic physical cooling transition zone. As the fluid displacement increases, the heat stripping effect continues to accumulate. The high-temperature steam, which was originally expanding violently, has its heat energy effectively reduced when it flows out of the end of the buffer section 213. This design allows the superheated steam to be suppressed and naturally cooled to a safe temperature range before reaching the outlet 214.

[0045] In some embodiments, the fluid channel has a guide surface 25 on the inner wall of the buffer section 213 that slopes downward toward the vaporization section 212, and the guide surface 25 is configured to guide the generated condensate back to the vaporization section 212.

[0046] Specifically, a downward-sloping guide surface 25 is formed on the inner wall of the buffer section 213, facing the bottom of the vaporization section 212. When water vapor undergoes intense heat exchange and condenses upon contact with the condenser on the inner wall of the buffer section 213, the gaseous vapor transforms into tiny liquid condensate droplets that adhere to the inner wall of the buffer section 213. As the condensate continuously precipitates and accumulates, the volume and mass of the droplets gradually increase. Under the spatial constraint of the inclined guide surface 25, the condensate droplets adhering to the wall are subjected to gravity, generating a downward mechanical force along the slope. When this gravitational force accumulates to the point that it breaks through the surface tension between the droplet and the pipe wall and is greater than the fluid drag force generated by the upward steam flow, the droplet begins to slide continuously down the guide surface 25. This design eliminates the potential for condensate to adhere to the wall and accumulate inside the cooling transition zone, ultimately ensuring that the outlet 214 can still stably output dry, saturated water vapor without droplets even under conditions of significant cooling.

[0047] In some practical applications, the portion of the vaporizer body 21 corresponding to the buffer section 213 has a funnel-shaped or curved structure. Specifically, the cross-section of the flow channel of the buffer section 213 gradually narrows along the fluid flow direction, and its inner wall surface transitions from the outlet end of the vaporization section 212 to the outlet 214 as a continuously contracting conical or curved surface. The generatrix of this conical surface has a downward inclination angle relative to the horizontal plane, thus naturally forming a guide surface 25 that slopes downward toward the vaporization section 212.

[0048] In some embodiments, a detachable structure 24 is provided on the side wall of the vaporizer body 21 corresponding to the vaporization section 212, and the detachable structure 24 is configured to be opened from the outside to expose the interior of the vaporization section 212.

[0049] Specifically, a maintenance port is provided on the side wall of the vaporizer body 21 corresponding to the vaporization section 212, and a detachable structure 24, such as a cover that can be screwed on mechanically, is installed at this port. Under normal operating conditions, the detachable structure 24 maintains an airtight seal with the vaporizer body 21, while under maintenance conditions, it serves as a passage to the interior of the vaporization section 212. When the equipment triggers a maintenance cycle or a decrease in heat transfer efficiency is detected, the operator removes the detachable structure 24 from the outside of the vaporizer body 21 and cleans the interior of the vaporization section 212.

[0050] In some embodiments, the integrated vaporizer 14 further includes an insulation layer. The insulation layer wraps around the exterior of the vaporizer body 21 and at least covers the outer wall surface of the vaporization section 212.

[0051] Specifically, the insulation layer wraps around the exterior of the vaporizer body 21 and completely covers the outer wall of the vaporization section 212. In the assembled state, the heating component 22 is sandwiched between the outer wall of the vaporization section 212 and the insulation layer, forming a sandwich-like encapsulation structure. When the heating component 22 is powered on and generates high temperature, the heat energy will instinctively radiate omnidirectionally to the cooler surroundings. At this time, the outer insulation layer constructs an isolation barrier. This barrier spatially cuts off the heat convection and heat radiation loss path of the heating component 22 to the external cold air. Due to the blockage of the external loss path, the high-density heat energy confined inside the insulation layer generates a cohesive effect, forcing unidirectional heat conduction, that is, all of it penetrates the pipe wall of the vaporizer body 21 and is injected into the fluid channel. This forced directional feedback of heat energy allows the internal liquid water to reach the boiling threshold at a higher heating rate and maintain a vigorous phase change vaporization state even under continuous water supply conditions.

[0052] In the above embodiments, the insulation layer is made of a material with low thermal conductivity, such as aluminum silicate fiber felt, aerogel felt, glass wool, or polyurethane foam. The thickness of the insulation layer can be selected according to the operating temperature of the vaporization section 212 and the requirements of the external environment. A metal foil reflective layer, such as aluminum foil, can also be wrapped on the outer surface of the insulation layer. This reflective layer reflects the outwardly radiated infrared heat flow back to the vaporizer body 21, further reducing radiative heat loss.

[0053] This disclosure also provides a humidification device for humidifying a room 11 to be humidified. The humidification device includes a pump body 12 and the aforementioned integrated vaporizer 14. The pump body 12 includes a liquid inlet and a liquid outlet, the liquid inlet being configured to connect to a water source 13; the water inlet 211 of the integrated vaporizer 14 is connected to the liquid outlet of the pump body 12, and the integrated vaporizer 14 is configured to connect to the room 11 to be humidified via an air outlet 214.

[0054] Specifically, the pump body 12 is equipped with relatively independent liquid inlet and liquid outlet ends. The liquid inlet end is configured to be directly connected to an external continuous or fixed water source 13, and the liquid outlet end of the pump body 12 is connected to the water inlet 211 of the integrated vaporizer 14. Simultaneously, the integrated vaporizer 14, as the terminal output unit of the entire unit, has its end outlet 214 oriented to directly communicate with the interior space of the humidification chamber 11. When the humidification device starts its working cycle, the pump body 12 first creates a continuous negative pressure zone at the liquid inlet end, using the negative pressure suction effect to actively draw static liquid water from the water source 13 into the pump body 12. Then, the pump body 12 converts the drawn-in liquid water into a high-pressure fluid with forced kinetic energy, and pumps it directly out from the liquid outlet end, forcibly pushing it into the water inlet 211 of the integrated vaporizer 14. The humidification device using the integrated vaporizer 14 provided in this application effectively solves the technical problem in related technologies where liquid water and condensate are easily sprayed into the chamber due to vaporization through slender pipes and delivery through long flexible hoses, thus disrupting the stability of the chamber's environment.

[0055] Optionally, the pump body 12 is configured with an anti-backflow structure; for example, the pump body 12 can be configured as a peristaltic pump. The peristaltic pump internally arranges a rotating rotor and a flexible extrusion tube, which connects the inlet and outlet ends. In both static and dynamic phases, at least one extrusion roller on the peristaltic pump rotor maintains complete compression and closure of the extrusion tube. This mechanically interfered closure creates a reverse shut-off structure in the fluid path of the pump body 12. Thus, the pumped metered liquid water explodes and boils in the high-temperature environment of the vaporization section 212, and the gas-liquid phase change generates a huge high-pressure expansion reaction force within the closed channel. When the backflow pressure reaches the inlet 211 and attempts to flow back into the water source 13, the peristaltic pump can block its backflow path.

[0056] In some embodiments, when the integrated vaporizer includes a heat insulation structure, a fixing connector is provided on the outer peripheral surface of the heat insulation structure 23; the vaporizer body 21 passes through the heat insulation structure 23 and the fixing connector and is fixed to the perforation of the humidification chamber 11.

[0057] Specifically, during the assembly of the humidification device, the vaporizer body 21 is directly connected to the humidification chamber 11, meaning the transitional flexible air supply hose between the vaporizer body 21 and the humidification chamber 11 is removed. Assembly personnel or automated equipment insert one end of the vaporizer body 21 corresponding to the air outlet 214 directly into the pre-drilled perforation on the side wall of the humidification chamber 11. Subsequently, mechanical torque is applied by tightening or flange fastening, causing mechanical interference and engagement between the fixed connector on the outer circumference of the insulation structure 23 and the mating structure at the edge of the perforation. With the continuous maintenance of the mechanical locking force, the connection node gains tensile and shock resistance. Simultaneously, the strongly compressed insulation structure 23 undergoes elastic deformation, filling the assembly gaps between metal components, thus forming a sealing ring that both blocks high-temperature conduction and is highly leak-proof. This configuration, by introducing a protective assembly structure with fixed connectors, replaces the flexible gas delivery hose with a high failure rate, ultimately providing the entire unit with a rigid direct connection node that offers high airtightness, high assembly efficiency, requires no later maintenance, and eliminates the risk of secondary condensation in long pipelines.

[0058] In some embodiments, the humidification device further includes a humidity sensor 15 and a controller 16. The humidity sensor 15 is used to acquire the humidity of the room 11 to be humidified; the controller 16 is electrically connected to the pump body 12, the heating component 22 of the integrated vaporizer 14, and the humidity sensor 15, respectively; the controller 16 is configured to adjust the pumping volume of the pump body 12 and the operating power of the heating component 22 according to the detection signal of the humidity sensor 15.

[0059] Specifically, the probe of the humidity sensor 15 is oriented or extends into the interior space of the humidification chamber 11. The controller 16 is electrically connected to the drive motor of the pump body 12, the heating component 22 on the outside of the integrated vaporizer 14, and the humidity sensor 15 inside. When the humidification device is in operation, the humidity sensor 15 collects the dynamic humidity physical quantity inside the space in real time and transmits this environmental parameter back to the controller 16. The controller 16 performs logical comparison and difference calculation with the system's preset humidity target curve. When the calculation result shows that the actual humidity is lower than the target threshold, the controller 16 instructs the pump body 12 to increase its speed to increase the pumping volume of liquid water, and simultaneously increases the working power of the heating component 22 to match the surge in water volume. A large amount of liquid water is then forced to undergo phase change in the vaporization section 212, generating a huge amount of saturated steam to rapidly increase the humidity of the chamber. Conversely, when the actual humidity approaches or reaches the target threshold, the controller 16 performs reverse calculations to reduce the speed of the pump body 12 and simultaneously lower the heat power of the heating component 22, so that the steam output smoothly converges.

[0060] In some embodiments, the humidification device further includes a temperature sensor 17. The temperature sensor 17 is used to acquire the temperature of the vaporization section 212 of the vaporizer body 21 and is electrically connected to the controller 16; the controller 16 is also configured to control the heating component 22 according to the feedback signal of the temperature sensor 17 to heat and maintain the temperature in the vaporization section 212 to a first temperature range, the first temperature range being 110°C to 160°C; the outer surface area of ​​the vaporizer body 21 in the buffer section 213 is configured to naturally cool the vaporized water vapor flowing through it to a second temperature range, the second temperature range being 95°C to 105°C, so that the water vapor discharged from the outlet 214 avoids secondary condensation.

[0061] Specifically, temperature sensor 17 is placed close to the heat exchange zone and electrically connected to controller 16. Since the vaporization section 212 requires a high latent heat of vaporization to overcome the phase transition barrier of liquid water molecules, controller 16, upon receiving real-time wall temperature feedback from temperature sensor 17, forcibly adjusts the heat output of heating component 22, precisely locking and maintaining the thermodynamic temperature within the vaporization section 212 within a first temperature range of 110°C to 160°C. In this high-temperature, high-enthalpy environment, the liquid water entering the vaporization section 212 can undergo instantaneous explosive boiling, eliminating the formation of unvaporized droplets. Immediately afterwards, superheated steam carrying a large amount of sensible heat crosses the fluid boundary and enters buffer section 213. At this time, as the steam flows through this section, its contained thermal energy is naturally dissipated to the outer wall in a measured amount based on Fourier's law of thermal conduction. By matching the length of the buffer section 213 with the surface heat dissipation coefficient, the high-speed flowing steam is naturally and smoothly reduced to a second temperature range of 95°C to 105°C before reaching the outlet 214.

[0062] In the above embodiments, the first temperature range can be set according to the user's actual needs, for example, the first temperature range can be 110℃, 120℃, 130℃, 140℃, 150℃ or 160℃. Similarly, the second temperature range can also be set according to the user's actual needs, for example, the second temperature range can be 95℃, 100℃ or 105℃.
