[0035] Reference drawingsFigures 1-3 As shown, a respiratory tube heat preservation sleeve comprises:

[0036] A sleeve 100, which is hollow tubular, has a heating layer 110 on the inside and a heat preservation layer 120 on the outside;

[0037] A connector 200 at one end of the sleeve 100 for connecting the respiratory tube and the mask;

[0038] The connector 200 is provided with an electrical module 300, which includes sensors, and the electrical module 300 and the heating layer 110 are electrically connected to the breathing machine. Through the double-layer heat preservation structure and the intelligent control system, the temperature and humidity of the airflow in the respiratory tube are maintained, the formation of condensed water is reduced, and the user's breathing experience is improved. The inside heating layer 110 provides constant temperature heating, the outside heat preservation layer 120 reduces heat loss, and the electrical module 300 in the connector 200 monitors the airflow data in real time through the sensors to realize intelligent control and dynamic adjustment, ensuring efficient and stable operation of the equipment.

[0039] The sleeve 100 is a hollow tubular structure with a heating layer 110 inside. The heating element keeps the airflow in the tube at a stable temperature, preventing the humid and hot airflow from condensing into water droplets due to cooling during transmission. The heat preservation layer 120 on the outside reduces the impact of the external environment on the airflow in the tube, ensuring that the heat is not lost. The connector 200 at one end of the sleeve 100 is responsible for connecting the heat preservation sleeve with the mask and the breathing machine, ensuring smooth airflow. The electrical module 300 is equipped with various sensors, such as temperature sensors, humidity sensors, airflow sensors, and pressure sensors, which monitor the airflow state in real time and work with the breathing machine system. According to the data feedback, the power of the heating layer 110 is automatically adjusted to ensure the maintenance of constant temperature.

[0040] The user connects one end of the heat preservation sleeve to the respiratory tube and the mask through the connector 200, and electrically connects the electrical module 300 and the heating layer 110 to the breathing machine to ensure power supply and data transmission. During use, the sensors monitor the temperature and humidity of the airflow and transmit the data to the breathing machine system through the electrical module 300. According to the actual situation, the temperature of the heating layer 110 is adjusted to ensure that the airflow in the respiratory tube is warm and comfortable, avoiding the formation of condensed water. When the equipment is disassembled, only the electrical connection is disconnected and the heat preservation sleeve is removed.

[0041] By heating the double design of layer 110 and heat preservation layer 120, effectively prevent the formation of condensation in the breathing tube, ensure the smooth flow of gas, improve the user experience. Real-time monitoring and automatic adjustment function of intelligent sensor, make the equipment can respond dynamically according to the change of environment, reduce energy consumption and prolong the service life of the equipment. Modular design makes the heat preservation sleeve easy to install, disassemble and maintain, improves the convenience and cleaning efficiency. Overall, this scheme not only improves the comfort and stability of the breathing machine, but also adapts to different use scenarios, providing safe and efficient breathing support for users.

[0042] In this embodiment, the sleeve 100 is provided with an opening and closing piece 130 along the axis direction of the sleeve 100, which extends to the two end edges of the sleeve 100; when the opening and closing piece 130 is opened, the sleeve 100 is in a sheet shape, and a gap is formed between the opening and closing piece 130 for the breathing tube to pass through; when the opening and closing piece 130 is closed, the sleeve 100 is a hollow tubular shape. Through the openable structure, the breathing tube heat preservation sleeve has convenience and flexibility, which is convenient for users to install, disassemble and clean. Compared with the traditional closed pipe sleeve, this openable design aims to solve the problem of complicated installation, while ensuring the heat preservation effect and meeting the convenience demand of users in daily use.

[0043] The sleeve 100 is designed with an opening and closing piece 130 along the axis direction, which extends through the two end edges of the sleeve 100. When the opening and closing piece 130 is opened, the sleeve 100 will unfold into a sheet shape, forming a gap for the breathing tube to pass through, and the breathing tube can be easily placed in it; when the opening and closing piece 130 is closed, the sleeve 100 forms a hollow tubular structure around the breathing tube, ensuring that the internal heating layer 110 and the external heat preservation layer 120 can work normally, maintaining the temperature stability of the airflow in the breathing tube, thereby preventing the generation of condensation.

[0044] When the user installs the heat preservation sleeve, he only needs to open the opening and closing piece 130, place the breathing tube in the unfolded sleeve 100, and then close the opening and closing piece 130 along the pipe axis direction, so that the heat preservation sleeve tightly wraps the breathing tube. When cleaning or replacing is needed, the user can operate in reverse to quickly disassemble the heat preservation sleeve. The opening and closing piece 130 can be a zipper, a magnetic strip or a magic tape, and the user can choose the appropriate way according to the actual use habit.

[0045] This design realizes convenient disassembly and cleaning through the flexible structure of the opening and closing piece 130, greatly simplifying the operation process of the user when using the heat preservation sleeve. At the same time, the hollow tubular structure after closing ensures the normal operation of the heating and heat preservation functions, avoiding the formation of condensation caused by the decrease of airflow temperature. In addition, this structure makes the equipment have good adaptability, the user can quickly disassemble the heat preservation sleeve for maintenance or replacement according to the use scene, prolongs the service life of the equipment, and improves the overall use experience and efficiency.

[0046] In this embodiment, the opening and closing member 130 is a zipper or a magnetic strip or a magic tape. By using a zipper or a magnetic strip or a magic tape as the opening and closing member 130, the breathing tube thermal insulation sleeve provides a convenient disassembly method, simplifies the operation process, and improves the flexibility of daily use and the convenience of maintenance. Compared with the traditional closed design, this opening and closing structure allows the user to easily install the breathing tube into the thermal insulation sleeve, while ensuring that it has good thermal insulation performance after being closed.

[0047] In this design, the zipper or magnetic strip or magic tape is distributed along the axial direction of the thermal insulation sleeve. When the opening and closing member 130 is opened, the thermal insulation sleeve will expand into a sheet structure, and the user can place the breathing tube in it; when the opening and closing member 130 is closed, the thermal insulation sleeve forms a tight hollow tubular structure around the breathing tube, ensuring that the heating layer 110 works normally, so that the airflow in the tube maintains a constant temperature. The zipper provides a firm mechanical closing method, which is suitable for scenarios that require higher stability; while the magnetic strip provides a faster opening and closing method, which is convenient for users to frequently disassemble and assemble.

[0048] When the user installs the thermal insulation sleeve, he only needs to open the zipper or magnetic strip or magic tape along the axial direction, expand the thermal insulation sleeve into a sheet, put the breathing tube in the middle, and then close the zipper or magnetic strip or magic tape to restore it to a hollow tube. According to different needs, the user can choose a zipper structure for more stable connection, or choose a magnetic strip for faster disassembly and assembly. When cleaning, maintaining or replacing the breathing tube, the user only needs to reverse the operation to quickly complete the disassembly. This design greatly improves the operation convenience of the thermal insulation sleeve, and the user does not need to take out the breathing tube from the fixed sleeve 100 with great effort, but easily completes the installation and disassembly through the opening and closing member 130. The high stability of the zipper ensures that the device does not easily come off during use, while the flexibility of the magnetic strip makes maintenance more efficient. In addition, this design does not affect the thermal insulation and heating functions, and can effectively wrap the breathing tube in the closed state to prevent heat loss and the formation of condensed water. Overall, the zipper and magnetic strip opening and closing member 130 design makes the device have good adaptability, easy maintenance and simple operation.

[0049] In the first embodiment, the heating layer 110 includes heating wires 111 uniformly distributed in the heating layer 110. By uniformly distributing the heating wires 111 in the heating layer 110, the constant temperature control of the airflow in the breathing tube is realized, preventing the generation of condensed water caused by the decrease of airflow temperature. The direct electrical connection design makes the installation and maintenance of the heating layer 110 more convenient, improves the flexibility and maintainability of the device, and at the same time ensures the safety and efficiency of the breathing machine system.

[0050] The heating wires 111 inside the heating layer 110 are evenly distributed, ensuring uniform surface temperature of the breathing tube during heating, avoiding local overcooling or overheating, and ensuring stable and warm airflow. The heating wires 111 are directly connected to the external breathing machine electrically, and the breathing machine system receives real-time data such as temperature and humidity from the sensor through the electrical module 300 to dynamically adjust the heating power and keep the airflow within the set optimal temperature range. This electrical connection method simplifies the installation process and facilitates user replacement or maintenance when needed.

[0051] During installation, the user directly connects the electrical connection port of the heating layer 110 to the breathing machine system and ensures that the heat preservation sleeve tightly wraps the breathing tube. After power-on, the electrical module 300 automatically adjusts the power of the heating wires 111 according to the information feedback from the sensor to maintain constant temperature of the airflow and avoid the formation of condensed water. When cleaning or replacement is needed, the user only needs to disconnect the electrical connection with the breathing machine system to conveniently disassemble the heating layer 110 for maintenance.

[0052] In this embodiment, the heating layer 110 includes at least one heating wire 111, and the two ends of the heating wire 111 extend out of the heating layer 110 from the same point to connect the electrical connector 112. Using at least one heating wire 111 in the heating layer 110 and connecting it to the electrical connector 112 by extending its two ends out of the heating layer 110 from the same point simplifies the power supply circuit, realizes a compact structure, and efficient power supply design. This design not only ensures the stability of the heating function, but also improves the convenience of installation and maintenance by optimizing the circuit layout.

[0053] In this design, the two ends of the heating wire 111 extend out from the same position and connect to the external breathing machine. This layout eliminates the need for complex wiring inside the heating layer 110 for traditional double-end power supply lines, making electrical connection simpler and more efficient. The electrical module 300 monitors the temperature and humidity of the airflow in the breathing tube in real time through the sensor and adjusts the current and power of the heating wire 111 according to the feedback information. This design ensures that the airflow maintains a stable temperature during transmission and prevents the formation of condensed water.

[0054] Reference is made to the accompanying drawings Figures 5-6As shown, in the second embodiment, the heating layer 110 includes a heating film, one, two or multiple pieces of which are evenly distributed in the heating layer 110. Through the uniform distribution of the thin sheet-shaped heating film, the constant temperature control of the airflow in the breathing tube is achieved. The heating film is thin and flexible, which can be more evenly attached to the inner wall of the breathing tube, making the heating more efficient and reducing heat loss. Compared with the heating wire, the heating film simplifies the arrangement of the heating layer and improves the overall heating efficiency and uniformity, reducing the formation of condensed water. The heating film is distributed inside the heating layer 110 and can be one, two or multiple pieces, evenly covering the inside of the sleeve, so that the temperature of the entire tube wall can be kept consistent during the heating process. The heating film is electrically connected to the breathing machine, receives data feedback from the sensor, and dynamically adjusts the power to maintain the airflow within the set temperature range. The thin sheet-shaped heating film can quickly respond to temperature adjustment requirements, ensuring stable airflow and avoiding condensation caused by uneven local area temperature.

[0055] The thin sheet design and uniform distribution of the heating film make it fit the inner wall of the breathing tube more closely, providing uniform and consistent temperature on the entire pipe surface. In contrast, the heating wire may have uneven temperature distribution due to its local concentrated structure, especially at the pipe bends. The thin sheet structure of the heating film makes the heating layer more compact and space-saving, suitable for lightweight design and portability requirements. Compared with the heating wire, the heating film can reduce the thickness to a greater extent, improving the comfort of the breathing equipment. The heating film has good flexibility and can adapt to various bends and movements of the pipe without being easily damaged. Compared with the heating wire, the heating film is more suitable for breathing tubes that require high flexibility and high frequency disassembly.

[0056] In this embodiment, the sensor is any one, two or more of a temperature sensor, a humidity sensor, an airflow sensor and a pressure sensor. Through the combination of multiple sensors, the airflow state in the breathing tube is monitored in real time to achieve intelligent temperature regulation and airflow management. The cooperation of different sensors such as temperature, humidity, airflow and pressure sensors can accurately feedback the environmental data in the breathing tube, help the breathing machine system to make dynamic adjustments, and ensure the comfortable experience of the user and the stable operation of the equipment.

[0057] The type and number of sensors can be freely combined according to different needs. For example, the temperature sensor monitors the temperature of the airflow in real time to ensure that the heating layer 110 works within the optimal range; the humidity sensor is used to detect the moisture content in the airflow to prevent excessive humidity from causing condensed water; the airflow sensor monitors the airflow speed to ensure smooth ventilation; the pressure sensor monitors the pressure change in the pipe to prevent discomfort caused by abnormal air pressure. The data of all sensors is fed back to the breathing machine system through the electrical module 300, and the system automatically adjusts the power of the heating layer 110 and the airflow parameters according to the feedback signals of different sensors to maintain the constant temperature, constant humidity and appropriate flow rate of the airflow, reducing the formation of condensed water.

[0058] In use, the user only needs to connect the heat preservation sleeve with the breathing machine electrical system, and the sensor automatically monitors the environmental data in the breathing tube and transmits it to the breathing machine system through the electrical module 300. The user does not need manual intervention, and the heating layer 110 will dynamically control the temperature and humidity according to the real-time data feedback by the sensor, ensuring the comfort of the airflow in the breathing tube. Through the combination of temperature, humidity, airflow and pressure sensors, the device has high intelligence and precise monitoring capability, ensuring the real-time balance of airflow temperature, humidity, flow rate and pressure, avoiding the formation of condensed water and improving the breathing comfort. The flexible combination of the multi-sensor system adapts to different environments and user needs, improving the applicability of the device. The real-time monitoring and dynamic adjustment function of the sensor not only reduces energy consumption, but also improves the safety and stability of the device.

[0059] Referring to the accompanying drawings Figure 4 In the embodiment shown, the detection part 310 of the sensor extends into the airway of the connector 200. The detection part 310 of the sensor is extended into the airway of the connector 200 to detect the key data such as temperature, humidity, airflow and pressure in the airway in real time and accurately. This arrangement ensures that the sensor can directly obtain first-hand information about the state of the airflow, thereby achieving more efficient and accurate monitoring and control, and providing timely feedback to the breathing machine system.

[0060] The detection part 310 of the sensor is arranged in the airway of the connector 200, close to the connection between the breathing tube and the mask. When the airflow passes through this position, the sensor can collect temperature, humidity, airflow and pressure data in the airway in real time. The collected data will be transmitted to the breathing machine control system through the electrical module 300, and the system will dynamically adjust the temperature and airflow parameters of the heating layer 110 according to different environments and use cases. In this way, it can ensure that the airflow in the breathing tube is always maintained in a comfortable state, while effectively preventing the formation of condensed water due to temperature or humidity fluctuations.

[0061] The design of extending the detection part 310 of the sensor into the airway makes data collection more accurate and timely, ensuring that the breathing machine system can quickly respond to environmental changes. This arrangement reduces monitoring delays and ensures the real-time temperature adjustment of the heating layer 110, further reducing the risk of condensed water formation. In addition, the position of the sensor detection part 310 is close to the key channel of the mask and airflow, which helps to optimize the airflow control of the breathing machine and improve the airflow comfort and user experience.

[0062] In this embodiment, the heat preservation layer is externally provided with a waterproof layer. The waterproof layer is arranged on the outer side of the heat preservation layer. This design aims to improve the waterproofness and durability of the heat preservation sleeve, prevent external moisture from penetrating into the heating layer and the heat preservation layer, and thus ensure the reliability and safety of the heat preservation sleeve in a humid environment. During heating, the heat preservation layer is responsible for reducing heat loss and ensuring stable airflow temperature in the pipe. The newly added waterproof layer serves as an external barrier to effectively prevent external moisture or water from penetrating into the heat preservation layer and the heating layer, avoiding temperature instability or electrical safety problems caused by water contacting the heating element. The waterproof layer is tightly attached to the outer side of the heat preservation layer through airtight design, without affecting the internal heating and heat preservation effect, while playing a role in isolating external moisture, ensuring safe operation of the equipment under various environmental conditions.

[0063] When the user installs the heat preservation sleeve, no additional operation is required for the waterproof layer. The waterproof layer is firmly attached to the outer side of the heat preservation layer during design, and can achieve protection function by directly sleeving into the breathing tube. During cleaning or maintenance, the waterproof layer can also effectively prevent water from entering the internal equipment during the cleaning process, and the user only needs to wipe the outer surface of the waterproof layer, making the maintenance operation simple and convenient.

[0064] A breathing device includes the aforementioned heat preservation sleeve, and is designed to be detachable or integrated with the breathing tube according to different needs and use scenarios of the user. This design takes into account the flexibility and integration of the equipment, ensuring the heat preservation effect while meeting the needs of different users for convenience, maintenance and use efficiency.

[0065] When the equipment adopts a detachable heat preservation sleeve, the user can install or remove the heat preservation sleeve as needed to adapt to use in different environments. For example, in an environment with low room temperature or high humidity, the heat preservation sleeve is used to maintain constant temperature of the airflow; while in a warm environment, the heat preservation sleeve can be detached to simplify the structure of the equipment.

[0066] When the equipment adopts an integrated heat preservation sleeve, the heat preservation layer 120, the heating layer 110 and the breathing tube are integrated, and are connected with the breathing machine system through fixed electrical connectors, realizing integration of heating and heat preservation functions, reducing the number of components of the equipment, and improving the overall stability and sealing performance.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
