Description

Technical Field

[0001] The invention belongs to the technical field of humidifiers and relates to a heating integrated humidifier. Background Art

[0002] The humidifier for ventilator is an important part of the ventilator. Its function is to heat and humidify the inhaled gas. Good heating and humidification can prevent and reduce secondary respiratory infections and stimulation to the cardiopulmonary system in patients with mechanical ventilation, and keep the alveoli moist. At the same time, it can also reduce the consumption of heat and respiratory water, making it difficult for sputum crusts to form in the airway, and can reduce the viscosity of secretions and promote expectoration.

[0003] like Figure 1 As shown, existing humidifiers usually adopt a split design, that is, the water tank and the heating base are separated. The heating element is installed on the base, and heat is indirectly transferred through the heat-conducting material at the bottom of the water tank. This structure requires heat to pass through the bottom wall of the water tank and then be transferred to the water body. The heat transfer path is long and the thermal efficiency is low, resulting in slow heating speed. In addition, this contact heat transfer heating method has extremely high requirements on the flatness of the bottom of the water tank. If the bottom of the water tank becomes bent or uneven due to heating or falling during long-term use, it will greatly affect the heating efficiency and temperature control accuracy. Summary of the invention

[0004] The object of the present invention is to provide a heating-integrated humidifier to address the deficiencies of the prior art, and to improve the heating efficiency and temperature control accuracy by directly integrating a heating element on the bottom of a water tank.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A heating integrated humidifier comprises a water tank and a base, wherein the water tank is provided with a cavity for containing a mixture of liquid and water vapor, and the water tank is provided with an air inlet and an air outlet communicated with the cavity;

[0007] The water tank is provided with a heat conducting plate, one side of the heat conducting plate is located in the cavity, and the other side of the heat conducting plate is provided with a heating element in close contact;

[0008] The base is used to supply energy to the heat conducting plate.

[0009] Furthermore, the heating element is a heating film or a heating wire.

[0010] Furthermore, it also includes a base, wherein the water tank and the base are integrated;

[0011] The base is fixedly connected to the heat conducting plate, one side of the heat conducting plate is located in the cavity, and the other side of the heat conducting plate faces the base.

[0012] Furthermore, it also includes a base, the water tank and the base are separate, and the water tank is electrically connected to the base through a contact.

[0013] Furthermore, it also includes a temperature sensor, which is located outside the cavity to monitor the temperature of the heating element or located inside the water tank to monitor the temperature of the liquid in the water tank.

[0014] Furthermore, the base is provided with a waterproof electrical interface, and the base is connected to external equipment through the waterproof electrical interface;

[0015] The waterproof electrical interface is electrically connected to the heating element and the temperature sensor respectively for power supply and signal transmission.

[0016] Furthermore, the base is provided with a central control unit and a temperature adjustment button, and the central control unit is electrically connected to the heating element and the temperature sensor respectively.

[0017] Furthermore, a wireless connection unit is provided in the base, and the base is connected to an external device via the wireless connection unit.

[0018] Furthermore, the heat conducting plate is embedded in the side wall of the water tank.

[0019] Furthermore, the water tank body is made of transparent material or is provided with a visible window.

[0020] By applying the technical solution of the present invention, the heating element is directly integrated on the heat conducting plate at the bottom of the water tank, forming a close contact, so that the heat is transferred to the water more directly and quickly. This structure reduces the heat transfer path, improves the heating efficiency, and overcomes the problem of reduced heating efficiency and temperature control accuracy caused by poor bottom flatness in traditional split designs.

[0035] Reference Figure 2-8 As shown, a heating integrated humidifier includes a water tank 100 and a base 200, wherein the water tank 100 is provided with a cavity 110 for containing a mixture of liquid and water vapor, and the water tank 100 is provided with an air inlet 120 and an air outlet 130 communicating with the cavity 110;

[0036] The water tank 100 is provided with a heat conducting plate 300, one side of the heat conducting plate 300 is located in the cavity 110, and the other side of the heat conducting plate 300 is provided with a heating element 400 in close contact;

[0037] The base 200 is used to supply energy to the heat conducting plate 300 .

[0038] The core idea of ​​this design is to integrate the heating element 400 directly onto the heat conducting plate 300 at the bottom of the water tank 100 to form an integrated heating structure, making heat transfer more direct and efficient. The traditional split humidifier is heated by the separate structure of the water tank 100 and the base 200. The heat needs to pass through the bottom wall of the water tank 100 and then be transferred to the water body, resulting in low efficiency and unstable temperature control. The integrated humidifier shortens the heat transfer path by tightly combining the heat conducting plate 300 and the heating element 400, so that the water in the water tank 100 can be quickly heated to the required temperature, ensuring the uniformity and stability of the humidification effect.

[0039] The cavity 110 in the water tank 100 is used to store a mixture of water and water vapor. The heat conducting plate 300 is embedded in the bottom of the water tank 100, in direct contact with the water body, and at the same time closely fits the heating element 400. The heating element 400 heats the heat conducting plate 300 under the power supply of the base 200, and quickly heats the water to the set temperature through efficient heat conduction. After the water vapor is generated, it is discharged through the air inlet 120 and the air outlet 130 of the water tank 100 and fully mixed with the air flow. The base 200 supplies power to the heat conducting plate 300, and the entire electrical system is integrated through the base 200 for power supply. The integrated design of the heating system makes temperature control and energy transmission more compact and safe, reduces energy loss, and improves heating efficiency.

[0040] The design integrates the heating element 400 and the heat conducting plate 300 at the bottom of the water tank 100, realizing direct heat transfer. This structure significantly shortens the heat transfer path, improves the heating efficiency compared to the traditional split heating structure, and makes the temperature control more accurate. It avoids the problem of uneven heating caused by poor bottom flatness or deformation of the water tank 100 in traditional humidifiers.

[0041] The heating process is more stable and uniform due to the close fit between the heating element 400 and the heat conducting plate 300. The direct contact heat conduction method allows the water to quickly reach the ideal temperature, while the water temperature is more stable, which helps to generate a uniform humidified airflow, improves the patient's comfort and ensures safety.

[0042] The integrated heating structure reduces the overall volume of the humidifier, optimizes the structure of the device, and makes the humidifier more compact and portable. This design is particularly suitable for use with a ventilator, providing users with a more portable and efficient humidifier option.

[0043] Since the heating element 400 and the heat conducting plate 300 are fixed inside the water tank 100, the structure is more stable, avoiding the wear and tear that may be caused by repeated disassembly of the base 200 and the water tank 100 in the traditional split design. This integrated structure also reduces the risk of water vapor leakage and short circuit, and enhances the durability and safety of the device.

[0044] In this embodiment, the heating element 400 is a heating film or a heating wire. By adopting the heating method of the heating film or the heating wire, combined with the integrated heating element 400 and the heat conducting plate 300 structure, the heat can be evenly and efficiently transferred to the water in the water tank 100. Compared with the traditional heating element 400, the heating film and the heating wire have the characteristics of fast heating speed, low power consumption and precise temperature control, which can better meet the needs of continuous and stable humidification of the humidifier.

[0045] The heating film is a thin film heating element 400 with a uniform heating surface, which can evenly distribute heat over a large area. The heating wire is a linear heating element 400, which can evenly transfer heat to the water through a coil structure or a design distributed at the bottom of the heat conducting plate 300.

[0046] Whether it is a heating film or a heating wire, they both have a relatively fast heating capability, so that the water can reach the set temperature in a short time. At the same time, these heating elements 400 can achieve precise temperature control based on sensor feedback while maintaining uniform heating, avoiding the water temperature from being too high or too low, and ensuring the stability of the gas humidification effect.

[0047] The thin film shape of the heating film and the linear structure of the heating wire provide a more flexible layout space for the design of the heating element 400, so that the humidifier can achieve efficient heating in a limited space, reduce the volume occupied by the heating element 400 in the device, and provide the possibility for the compactness and portability of the overall structure.

[0048] Reference Figure 2-6 As shown, in the first embodiment, a base 200 is also included, and the water tank 100 and the base 200 are integrated;

[0049] The base 200 is fixedly connected to the heat conducting plate 300, one side of the heat conducting plate 300 is located in the cavity 110, and the other side of the heat conducting plate 300 faces the base 200. The humidifier design adopts an 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 cavity 110 of the water tank 100, so that heat can be efficiently transferred to the water body. This design combines the advantages of compact structure, small equipment and efficient heating, meeting the needs of humidifiers in medical and portable scenarios.

[0050] The cavity 110 of the water tank 100 is used to store water, and the heat conducting plate 300 is fixed to the bottom of the water tank 100 and fits tightly with the heating element 400. The base 200 provides energy for the heating element 400, and the heat is directly transferred to the water in the cavity 110 through the heat conducting plate 300, and the water vapor is generated by heating, and is discharged through the air inlet 120 and the air outlet 130 of the water tank 100 for use by the ventilator. Due to the integrated structure of the water tank 100 and the base 200, higher sealing requirements are required for equipment cleaning, especially when cleaning the inside of the water tank 100 to prevent water vapor and liquid from leaking into the heating and electrical parts. Therefore, high-performance sealing materials and closed structures are used in the design to ensure the airtightness and waterproofness of the water tank 100 during use and cleaning, thereby extending the service life of the equipment.

[0051] Through the integrated structure, the water tank 100 and the base 200 are integrated, which reduces the size of the device and makes the humidifier more compact and portable. This design is particularly suitable for use with a ventilator, making the device easier to carry and operate in various environments. The heat conducting plate 300 is in direct contact with the heating element 400, reducing the heat loss caused by separation in a traditional split humidifier. The close-contact heating structure achieves more efficient heat transfer and achieves precise temperature control through the temperature sensor 500, ensuring that the water body is heated to the set temperature in a shorter time and maintaining a constant humidified airflow output. The integrated structure removes the sealing interface between the water tank 100 and the base 200, avoiding the problem of water vapor leakage at the interface. In order to facilitate cleaning and maintain the sealing performance of the equipment, this design uses high-quality sealing materials and designs on the integrated structure to ensure that there will be no liquid leakage during the cleaning process, ensuring the safety of the heating component and the long-term use of the equipment.

[0052] Reference Figure 6As shown, in the second implementation case, a base 200 is also included, and the water tank 100 and the base 200 are split, and the water tank 100 is electrically connected to the base 200 through contacts. The core idea of ​​this design is to separate the water tank 100 from the base 200, so that the water tank 100 can be easily disassembled and cleaned to meet the high-frequency cleaning needs, especially in medical and home use environments, which helps to keep the equipment clean. The electrical connection between the water tank 100 and the base 200 is made through electrical contacts, which avoids the inconvenience of cleaning caused by the traditional fixed connection, making the disassembly and assembly of the water tank 100 simpler and faster. At the same time, the electrical contact design ensures the stability of power supply, so that the split humidifier achieves a balance between maintenance convenience and heating efficiency.

[0053] The water tank 100 and the base 200 are designed to be separated. The base 200 includes a heating element 400 and a temperature control system, and the water tank 100 is electrically connected to the base 200 through contacts. When the water tank 100 is placed on the base 200, the contacts automatically contact the power supply, starting the heating process. The heating element 400 quickly transfers heat to the water in the water tank 100, generating water vapor for humidification. The split design allows the water tank 100 to be removed and cleaned separately. After use, there is no need to clean the entire humidifier, only simple maintenance of the water tank 100 is required. In addition, the independent water tank 100 avoids the risk of water vapor contacting the electrical components of the base 200 during cleaning, thereby improving the safety of the equipment.

[0054] In this embodiment, a temperature sensor 500 is also included. The temperature sensor 500 is located outside the cavity 110 to monitor the temperature of the heating element 400 or is located inside the water tank 100 to monitor the temperature of the liquid in the water tank 100. The temperature sensor 500 is designed to provide two different arrangements: one is to be located in the base 200 to indirectly monitor the temperature of the heating element 400; the other is to be directly arranged in the water tank 100 to directly detect the temperature of the water body. Each method has its own advantages and limitations and is suitable for different cost, accuracy and sealing requirements.

[0055] The indirect measurement temperature control temperature sensor 500 is located in the base 200: by arranging the temperature sensor 500 near the heating element 400, the temperature of the heating element 400 is indirectly measured, and the heating process is controlled by a negative feedback system. The sensor monitors the temperature of the heating element 400 in real time, and adjusts the heating power based on the data to prevent overheating or dry burning. The structure of this solution is relatively simple, and the temperature sensor 500 does not need to directly contact the water body, thereby reducing the sealing requirements and production costs of the humidifier.

[0056] Direct measurement temperature control temperature sensor 500 is placed in water tank 100: The temperature sensor 500 is placed directly in the chamber 110, and the temperature is controlled by monitoring the actual temperature of the water body. This design is more accurate and can quickly respond to changes in water temperature to ensure that the water body reaches the set humidification temperature. Although this direct measurement has more advantages in accuracy, it requires a more complex waterproof sealing structure and reliable electrical connection, so the cost is higher.

[0057] Reference Figure 7 As shown, in the third implementation example, the base 200 is provided with a waterproof electrical interface 600, and the base 200 is connected to an external device through the waterproof electrical interface 600;

[0058] The waterproof electrical interface 600 is electrically connected to the heating element 400 and the temperature sensor 500 for power supply and signal transmission. The humidifier is connected to an external device such as a ventilator through the waterproof electrical interface 600 to realize power supply and temperature monitoring data transmission without the need for an independent control unit or central control system to be integrated inside the humidifier. This design makes full use of the centralized control function of the ventilator, simplifies the structure of the humidifier, and significantly reduces the manufacturing cost and volume of the device.

[0059] The waterproof electrical interface 600 in the humidifier base 200 provides power to the heating element 400 and transmits the data of the temperature sensor 500 to the ventilator central control system. The ventilator automatically adjusts the heating power of the humidifier according to the received temperature data to ensure the stability and safety of the humidification effect.

[0060] The central control system of the ventilator receives the temperature information of the humidifier and adjusts the heating power through negative feedback to avoid excessive or insufficient water temperature and ensure that the humidity of the breathing airflow is moderate. Heating and temperature control management can be completed without the need for an independent control unit in the humidifier.

[0061] The core of this design is to remove the independent control unit in the humidifier, connect it to the ventilator through the waterproof electrical interface 600, and transfer the heating and temperature control management of the humidifier to the central control system of the ventilator for centralized control. The waterproof electrical interface 600 ensures the safety of the humidifier in a humid environment, while supporting the power supply of the heating element 400 and the data transmission of the temperature sensor 500 to achieve coordinated operation between devices. This design simplifies the electrical structure of the humidifier, making the humidifier more compact and portable, and suitable for use in medical equipment.

[0062] Reference Figure 8As shown, in the fourth implementation example, the base 200 is provided with a central control unit and a temperature adjustment 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 equipped with a central control unit and a temperature adjustment button, and the heating element 400 and the temperature sensor 500 are controlled by the central control system, respectively, so that the humidifier can operate independently and is compatible with a variety of ventilator models. This design integrates independent control functions in the humidifier, making the device more independent and compatible, and no longer relying on the central control system of a specific ventilator.

[0063] The temperature sensor 500 monitors the water temperature in real time and transmits the data to the central control unit. The central control unit adjusts the power of the heating element 400 according to the feedback temperature value to ensure that the water temperature is maintained within the set range and provide a stable humidification airflow. The temperature button allows users to manually adjust the temperature according to their needs to adapt to different seasons, indoor temperatures or personal preferences, achieving more flexible humidification management.

[0064] The core of this design is that through the independent central control unit and temperature adjustment button, the humidifier can not only be used with the ventilator, but also can be operated independently without a specific ventilator. The central control unit directly controls the heating and temperature monitoring functions of the humidifier to adapt to different environments and user needs. The temperature adjustment button allows the user to manually adjust the heating temperature, providing more flexible settings for different humidification needs.

[0065] In the implementation case, the base 200 is provided with a wireless connection unit, and the base 200 is connected to an external device through the wireless connection unit. A wireless connection unit is provided in the humidifier base 200, and the wireless module is connected to an external device to achieve remote control and real-time monitoring. This design gives the humidifier greater intelligence and operational flexibility, and is particularly suitable for the convenient operation requirements of medical scenarios and home environments.

[0066] The wireless connection unit is embedded in the base 200 and is connected to an external device via Wi-Fi, Bluetooth or other wireless protocols, allowing the user to control the functions of the humidifier in real time within a certain range, such as adjusting the temperature, turning on and off the heating, checking the water level, etc. The user can check the working status of the humidifier such as the current temperature and humidity level at any time through the application or control platform on the smart device, and adjust the temperature and heating power to ensure that the humidifier continues to provide the required humidification effect.

[0067] The addition of a wireless connection unit enables the humidifier to be remotely controlled. Users can complete operations such as switching and temperature adjustment without approaching the device. It is suitable for a variety of application scenarios such as wards and homes, and improves the convenience and safety of use. Users can view the real-time status of the humidifier through an external smart device, which facilitates timely adjustments to ensure that the humidification effect always meets the requirements. This design is particularly suitable for hospital monitoring scenarios, where medical staff can monitor and adjust the equipment at any time without manually operating the device itself. Through the wireless connection unit, the humidifier can be compatible with a variety of smart platforms, such as smart home systems or hospital information systems. This design not only improves the intelligence level of the device, but also enables the humidifier to be better integrated into smart homes or medical Internet of Things, enhancing overall connectivity.

[0068] In this embodiment, the heat conducting plate 300 is embedded in the side wall of the water tank 100. By embedding the heat conducting plate 300 in the side wall of the water tank 100, the water body can be evenly heated from multiple directions. In the traditional design, the heating element 400 is usually located at the bottom of the water tank 100, which easily leads to a higher temperature of the water body at the bottom and a lower temperature of the water body at the top, affecting the humidification effect. The design of side wall heating increases the contact area between the water body and the heating surface, so that the heat can be more evenly transferred to the entire water body, thereby ensuring the uniformity and stability of the humidification effect.

[0069] After the heat conducting plate 300 is embedded in the side wall of the water tank 100, the heat is transferred to the water body from multiple directions through the side wall, avoiding the situation where the heat is concentrated at the bottom of the water tank 100, so that the water body can be heated evenly. This design makes the temperature gradient inside the water body smaller, and the generated water vapor is more uniform, which helps to provide a stable humidification effect. The side wall embedded heat conducting plate 300 provides a larger heating surface, allowing the water body to reach the target temperature more quickly. The heat is transferred along the side wall, which reduces the heating time, improves the response speed of the humidifier, and ensures a more stable humidification effect.

[0070] The design of the embedded heat conductive plate 300 on the side wall makes the water body heated more evenly, avoiding the problem of local overheating that may be caused by traditional bottom heating. Through multi-directional heating of the side wall, the temperature of the water body is more stable and the humidified airflow generated is more uniform. Traditional bottom heating methods are prone to temperature stratification, resulting in hotter water at the bottom and cooler water at the top. Side wall heating can transfer heat from multiple directions, eliminate temperature stratification, and make the entire water body reach a uniform temperature, which is more suitable for humidification needs. The design of the side wall heat conductive plate 300 increases the heating area, allowing the water body to reach the set temperature faster and shorten the preheating time. The improvement in heating efficiency not only saves energy, but also improves the response speed of the equipment, providing users with a more immediate humidification experience.

[0071] In this embodiment, the water tank 100 is made of transparent material or has a visible window. Through the transparent material or the visible window, the user can check the water quantity and water quality in the water tank 100 at any time. This function is crucial for the use of humidifiers, especially in medical and home environments. The transparent water tank 100 or the visible window reduces the user's guesswork about the water level and water quality, and prevents insufficient water or unclean water from affecting the humidification effect and safety of the device.

[0072] Through the transparent water tank 100 or the visible window, the user can easily see the water level in the water tank 100, ensuring that the humidifier works under the appropriate water volume conditions, avoiding the humidification effect affected by too little water, and even causing the risk of dry burning. The user can directly observe the water quality in the water tank 100, promptly discover possible impurities or dirt in the water body, ensure the water body is clean, and maintain the good performance of the humidifier. At the same time, the transparent design makes it easy for the user to replace new water when the water quality is poor, ensuring the hygiene of the humidified gas.

[0073] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
