Referring to fig. 2-8, a heating integrated humidifier comprises a water tank 100 and a base 200, wherein a cavity 110 for accommodating liquid and water vapor is arranged in the water tank 100, and an air inlet hole 120 and an air outlet hole 130 which are communicated with the cavity 110 are arranged on the water tank 100;

The water tank 100 is provided with a heat conducting plate 300, one side of the heat conducting plate 300 is positioned in the accommodating cavity 110, and the other side is provided with a heating element 400 which is in close contact;

The base 200 is used to power the heat conductive plate 300.

The core idea of the design is that the heating element 400 is directly integrated on the heat conducting plate 300 at the bottom of the water tank 100 to form an integrated heating structure, so that heat transfer is more direct and efficient. The conventional split humidifier is heated by the separated structure of the water tank 100 and the base 200, and heat needs to be conducted to the water body through the bottom wall of the water tank 100, so that the efficiency is low and the temperature control is unstable. And the integrated humidifier shortens the heat transfer path by tightly combining the heat conductive plate 300 and the heating element 400, so that water in the water tank 100 can be rapidly heated to a desired temperature, and uniformity and stability of the humidifying effect are ensured.

The cavity 110 in the water tank 100 is used for storing a mixture of water and water vapor. The heat conductive plate 300 is embedded in the bottom of the water tank 100 to be in direct contact with the water body while closely fitting the heating element 400. The heating element 400 heats the heat conductive plate 300 under the power of the base 200, and rapidly heats water to a set temperature through efficient heat conduction. After the water vapor is generated, it is discharged through the air inlet hole 120 and the air outlet hole 130 of the water tank 100 to be sufficiently mixed with the air flow. The base 200 provides power to the thermally conductive plate 300 and the entire electrical system is powered integrally through the base 200. The heating system is integrally designed, so that temperature control and energy transmission are tighter and safer, energy loss is reduced, and heating efficiency is improved.

The design integrates the heating element 400 and the heat conducting plate 300, and is integrated at the bottom of the water tank 100, so that direct heat transfer is realized. This kind of structure has shortened the heat transfer route obviously, has promoted heating efficiency compared traditional split type heating structure to make the control by temperature change more accurate. The problem of uneven heating caused by poor flatness of the bottom or deformation of the water tank 100 in the conventional humidifier is avoided.

By the close fitting of the heating element 400 to the heat conductive plate 300, the heating process is more stable and uniform. The direct contact heat conduction mode enables the water body to reach the ideal temperature rapidly, meanwhile, the water temperature is more stable, uniform humidifying airflow is generated, comfort of a patient is improved, and safety is guaranteed.

The integrated heating structure reduces the whole volume of the humidifier, optimizes the structure of the equipment, and makes the humidifier more compact and portable. The design is particularly suitable for being matched with a breathing machine, and provides more portable and more efficient humidifier selection for users.

Because the heating element 400 and the heat conductive plate 300 are fixed inside the water tank 100, the structure is more stable, and the abrasion possibly caused by repeated disassembly of the base 200 and the water tank 100 in the conventional split design is avoided. The integrated structure also reduces the risks of water vapor leakage and short circuits, and enhances the durability and use safety of the device.

In this embodiment, the heating element 400 is a heating film or a heating wire. By adopting a heating mode of a heating film or a heating wire, and combining the integrated structure of the heating element 400 and the heat conducting plate 300, heat can be uniformly and efficiently transferred to the water body in the water tank 100. Compared with the traditional heating element 400, the heating film and the heating wire have the characteristics of high heating speed, low power consumption and accurate temperature control, and can better meet the continuous and stable humidifying requirement of the humidifier.

The heating film is a thin film-shaped heating element 400 having a uniform heating surface, and can uniformly distribute heat over a large area. The heating wire is a linear heating element 400, and can uniformly transfer heat to the water body through a coil structure or a design distributed at the bottom of the heat conducting plate 300.

Both the heating film and the heating wire have quick heating capacity, so that the water body can reach the set temperature in a short time. Meanwhile, under the condition of keeping uniform heating, the heating elements 400 can realize accurate temperature control according to sensor feedback, so that the water body temperature is prevented from being too high or too low, and the stability of the gas humidifying effect is ensured.

The film form of the heating film and the linear structure of the heating wire provide more flexible layout space for the design of the heating element 400, so that the humidifier can realize high-efficiency heating in a limited space, the occupation of the heating element 400 on the equipment volume is reduced, and the possibility is provided for the compactness and portability of the whole structure.

Referring to fig. 2-6, in a first embodiment, the water tank 100 further comprises a base 200, and the water tank 100 and the base 200 are integrated;

The base 200 is fixedly connected with the heat conducting plate 300, one side of the heat conducting plate 300 is located in the accommodating cavity 110, and the other side of the heat conducting plate 300 faces the base 200. The humidifier adopts the integrated structure of the water tank 100 and the base 200, the heat conducting plate 300 is fixed on the base 200, and one side of the heat conducting plate 300 directly faces the containing cavity 110 of the water tank 100, so that heat can be efficiently transferred to the water body. The design combines the advantages of compact structure, small equipment and high-efficiency heating, and meets the requirements of the humidifier in medical and portable scenes.

The cavity 110 of the water tank 100 is used for storing water, and the heat conducting plate 300 is fixed at the bottom of the water tank 100 and closely attached to the heating element 400. The base 200 supplies power to the heating element 400, heat is directly transferred to the water body in the cavity 110 through the heat-conducting plate 300, water vapor is generated by heating, and the water vapor is discharged through the air inlet hole 120 and the air outlet hole 130 of the water tank 100 for the breathing machine. Since the integrated structure of the water tank 100 and the base 200 requires higher sealing requirements for cleaning the equipment, particularly when cleaning the inside of the water tank 100, leakage of moisture and liquid to the heating and electrical parts is avoided. Therefore, a high-performance sealing material and a closed structure are adopted in the design to ensure the air tightness and the water resistance of the water tank 100 during use and cleaning, thereby prolonging the service life of the equipment.

Through the integral structure, the water tank 100 and the base 200 are integrated, the volume of the equipment is reduced, and the humidifier is more compact and portable. The design is particularly suitable for being matched with a respirator, so that the device is easier to carry and operate in various environments. The heat conductive plate 300 is directly in contact with the heating element 400, reducing heat loss due to separation in the conventional split type humidifier. The close contact heating structure achieves more efficient heat transfer and precise temperature control through the temperature sensor 500, ensures that the water body is heated to a set temperature in a short time, and maintains constant humidifying airflow output. The integral structure removes the sealing interface between the water tank 100 and the base 200, and avoids the problem of water vapor leakage at the interface. In order to facilitate cleaning and maintain the sealing performance of the equipment, the design adopts high-quality sealing materials and designs on an integrated structure, so that liquid leakage can not occur in the cleaning process, and the safety of the heating assembly and the long-term use of the equipment are ensured.

Referring to fig. 6, in the second embodiment, the water tank 100 is separated from the base 200, and the water tank 100 is electrically connected to the base 200 through contacts. The core idea of the design is to separate the water tank 100 from the base 200, so that the water tank 100 can be easily disassembled and cleaned, and the high-frequency cleaning requirement is met, especially in medical and household use environments, and the sanitation of equipment is maintained. The electric connection between the water tank 100 and the base 200 is carried out through the electric contact, so that the inconvenience in cleaning caused by the traditional fixed connection is avoided, and the water tank 100 is simpler and faster to disassemble and assemble. Meanwhile, the electric contact design ensures the power supply stability, so that the split humidifier balances the maintenance convenience and the heating efficiency.

The water tank 100 and the base 200 are separately designed, the base 200 contains the heating element 400 and the temperature control system, and the water tank 100 is electrically connected with the base 200 through contacts. When the water tank 100 is placed on the base 200, the contacts automatically contact the power supply, the heating process is started, the heating element 400 rapidly transfers heat to the water body in the water tank 100, and water vapor is generated for humidification. The split design allows the water tank 100 to be detached and cleaned independently, so that the whole humidifier is not required to be cleaned after the split type water tank is used, and only the water tank 100 is required to be simply maintained. In addition, the independent water tank 100 avoids the risk of water vapor contacting the electrical components of the base 200 during cleaning, and improves the safety of the equipment.

In this embodiment, a temperature sensor 500 is further included, where the temperature sensor 500 is located outside the cavity 110 for monitoring the temperature of the heating element 400 or located inside the water tank 100 for monitoring the temperature of the liquid in the water tank 100. The temperature sensor 500 design provides two different arrangements, namely, one in the base 200 to indirectly monitor the temperature of the heating element 400, and the other in the water tank 100 to directly detect the temperature of the water body. Each approach has advantages and limitations that are applicable to different cost, precision and sealing requirements.

An indirect measurement temperature-controlled temperature sensor 500 is located within the base 200. By arranging the temperature sensor 500 in the vicinity of the heating element 400, the temperature of the heating element 400 is indirectly measured, and the heating process is controlled using a negative feedback system. The sensor monitors the temperature of the heating element 400 in real time, adjusts the heating power based on the data, and prevents overheating or dry burning. The scheme has a relatively simple structure, and the temperature sensor 500 does not need to be in direct contact with the water body, so that the sealing requirement and the production cost of the humidifier are reduced.

The temperature sensor 500 is directly placed in the water tank 100 by directly placing the temperature sensor 500 in the cavity 110 and controlling the temperature by monitoring the actual temperature of the water body. The design is more accurate, can respond to the temperature change fast, ensures that the water reaches the humidifying temperature of settlement. Such direct measurement, while more advantageous in terms of accuracy, requires a more complex watertight seal and reliable electrical connection, and is therefore costly.

Referring to fig. 7, in a third embodiment, the base 200 is provided with a waterproof electrical interface 600, and the base 200 is connected with an external device through the waterproof electrical interface 600;

The waterproof electrical interface 600 is electrically connected to the heating element 400 and the temperature sensor 500, respectively, for supplying power and transmitting signals. The humidifier is connected with external equipment such as a breathing machine through the waterproof electrical interface 600, so that power supply and temperature monitoring data transmission are realized, and an independent control unit or a central control system is not required to be integrated inside the humidifier. The design fully utilizes the centralized control function of the breathing machine, simplifies the structure of the humidifier, and obviously reduces the manufacturing cost and the volume of the equipment.

The watertight electrical interface 600 in the humidifier base 200 provides power to the heating element 400 on the one hand and transmits data from the temperature sensor 500 to the ventilator central control system on the other hand. The breathing machine automatically adjusts the heating power of the humidifier according to the received temperature data, so that the stability and safety of the humidifying effect are ensured.

The central control system of the breathing machine receives temperature information of the humidifier, and adjusts heating power through negative feedback, so that overhigh or insufficient water temperature is avoided, and moderate humidity of breathing air flow is ensured. The heating temperature control management can be completed without an independent control unit in the humidifier.

The core of the design is to remove an independent control unit in the humidifier, connect with the breathing machine through a waterproof electrical interface 600, and transfer the heating and temperature control management of the humidifier to a central control system of the breathing machine for centralized control. The waterproof electrical interface 600 ensures the safety of the humidifier in use in a humid environment, while supporting the power supply of the heating element 400 and the data transmission of the temperature sensor 500, enabling coordinated operation between the devices. The design simplifies the electrical structure of the humidifier, so that the humidifier is more compact and portable, and is suitable for being matched with medical equipment.

Referring to fig. 8, in the fourth embodiment, the base 200 is provided with a central control unit and a temperature adjusting button, and the central control unit is electrically connected to the heating element 400 and the temperature sensor 500, respectively. The humidifier base 200 is provided with a central control unit and a temperature adjusting button, and the heating element 400 and the temperature sensor 500 are respectively controlled by the central control system, so that the humidifier can independently operate and is compatible with various breathing machine models. The design integrates an independent control function in the humidifier, so that the device has stronger independence and compatibility and does not depend on a central control system of a specific breathing machine.

The temperature sensor 500 monitors the water temperature in real time and transmits data to the central control unit. The central control unit adjusts the power of the heating element 400 according to the fed-back temperature value, ensures that the water temperature is maintained within a set range, and provides stable humidifying airflow. The temperature button enables a user to manually adjust the temperature according to requirements, is suitable for different seasons, indoor temperatures or personal preference, and achieves more flexible humidification management.

The core of the design is that through the independent central control unit and the temperature adjusting button, the humidifier can be matched with the breathing machine for use, and can also independently operate under the condition of being separated from a specific breathing machine. The central control unit directly controls the heating and temperature monitoring functions of the humidifier, and is suitable for different environments and user requirements. The temperature adjusting button enables a user to manually adjust the heating temperature, and more flexible setting is provided for different humidification requirements.

In an embodiment, a wireless connection unit is disposed in the base 200, and the base 200 is connected with external equipment through the wireless connection unit. A wireless connection unit is arranged in the humidifier base 200, and is connected with external equipment through the wireless module, so that remote control and real-time monitoring are realized. The design gives the humidifier stronger intelligence and operation flexibility, and is particularly suitable for medical scenes and convenient operation requirements of home environments.

The wireless connection unit is embedded in the base 200, and is connected with an external device through Wi-Fi, bluetooth or other wireless protocols, allowing a user to control functions of the humidifier in real time within a certain range, such as adjusting temperature, switching heating, checking water level, etc. A user can check the working state of the humidifier, such as the current temperature and humidity level, at any time through an application program or a control platform on the intelligent device, and adjust the temperature and heating power to ensure that the humidifier continuously provides the required humidification effect.

The humidifier can be remotely controlled by the aid of the wireless connection unit, a user can finish operations such as switching and temperature adjustment without approaching equipment, the humidifier is suitable for various application scenes such as wards and families, and convenience and safety of use are improved. The user can check the real-time state of the humidifier through the external intelligent equipment, so that timely adjustment is facilitated, and the humidification effect is ensured to meet the requirements all the time. The design is particularly suitable for a hospital monitoring scene, and medical staff can monitor and adjust equipment at any time without manually operating the equipment. Through the wireless connection unit, the humidifier can be compatible with various intelligent platforms, such as an intelligent home system or a hospital informatization system. The design not only improves the intelligent level of equipment, but also enables the humidifier to be better integrated into intelligent home or medical internet of things, and enhances the overall interconnectivity.

In this embodiment, the heat-conducting plate 300 is embedded in the sidewall of the water tank 100. By embedding the heat conductive plate 300 into the sidewall of the water tank 100, uniform heating of the water body from multiple directions is achieved. In conventional designs, the heating element 400 is usually located at the bottom of the water tank 100, which easily results in a higher temperature of the water at the bottom and a lower temperature of the water at the upper part, which affects the humidification effect. The design of the side wall heating increases the contact area between the water body and the heating surface, so that heat can be more uniformly transferred to the whole water body, and the uniformity and stability of the humidifying effect are ensured.

After the heat conducting plate 300 is embedded in the side wall of the water tank 100, heat is transferred to the water body from multiple directions through the side wall, so that the condition that the heat is concentrated at the bottom of the water tank 100 is avoided, and the water body can be heated uniformly. The design makes the temperature gradient inside the water body smaller, and the generated water vapor is more uniform, thereby being beneficial to providing stable humidifying effect. The side wall embedded thermally conductive plate 300 provides a larger heating surface that enables the water body to reach the target temperature more quickly. Heat is transferred along the side wall, heating time is reduced, response speed of the humidifier is improved, and humidification effect is ensured to be more stable.

The design of the side wall embedded heat conducting plate 300 enables the water body to be heated more uniformly, and the problem of local overheating possibly caused by traditional bottom heating is avoided. Through the multidirectional heating of lateral wall, water temperature is more stable, and the humidifying air current of production is more even. Temperature stratification easily occurs in the traditional bottom heating mode, so that the bottom water body is hotter and the upper layer is cooler. The side wall heating can transfer heat from a plurality of directions, eliminates the temperature layering phenomenon, enables the whole water body to reach uniform temperature, and is more suitable for humidification requirements. The design of the side wall heat-conducting plate 300 increases the heating area, enables the water body to reach the set temperature faster, and shortens the preheating time. The improvement of heating efficiency not only saves energy, but also improves the response speed of the equipment, and provides more instant humidifying experience for users.

In this embodiment, the main body of the water tank 100 is made of transparent material or provided with a visible window. Through the transparent material or the visual window, a user can check the water quantity and water quality state in the water tank 100 at any time. This function is critical for the use of humidifiers, especially in medical and household environments. The transparent water tank 100 or the visual window reduces the guess of the water level and the water quality by the user, and prevents the humidification effect and the safety of the equipment from being affected by insufficient water quantity or unclean water quality.

Through transparent water tank 100 or visual window, the user can easily see the water level height in water tank 100, ensures that the humidifier works under the appropriate water yield condition, avoids the too little humidification effect of influence of water yield, even causes the dry combustion method risk. The user can directly observe the water quality condition in the water tank 100, discover possible impurities or dirt in the water body in time, ensure the water body to be clean, and maintain the good performance of the humidifier. Meanwhile, the transparent design is convenient for a user to replace new water when the water quality is poor, so that the sanitation of the humidified gas is ensured.

It should be noted that the above-mentioned embodiments are merely preferred embodiments of the present invention, and the present invention is not limited thereto, but may be modified or substituted for some of the technical features thereof by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
