Description

Technical Field

[0001] This utility model relates to the technical field of heating elements for ventilators, and in particular to an integrated heating assembly and a ventilator. Background Technology

[0002] Ventilators, as medical devices for treating respiratory diseases, play a vital role in both clinical and home treatment. They are widely used for respiratory failure due to various causes, respiratory management during surgery under anesthesia, respiratory support therapy, and emergency resuscitation. Humidifiers, as auxiliary equipment surrounding ventilators, are an essential component of the machine.

[0003] The function of a humidifier is to warm and humidify the air entering the user's mouth and nose through the ventilator, ensuring that the air entering the user's lungs is sufficiently comfortable, preventing and reducing irritation to the respiratory tract and cardiopulmonary system from the machine, and keeping the lungs and trachea moist. In cold or dry environments, providing warm air to the face area inside and around the mask may be more comfortable than providing cold air. Therefore, the humidifier needs to be heated to ensure that the air output from the humidifier has a certain level of humidity and temperature, which is important for the user.

[0004] In related technologies, pure resistance heating is often used. Common pure resistance heating methods include PI film (polyimide film), silicone rubber, and ceramic heating. Among these methods, ceramic heating components are expensive, fragile, and have relatively fixed shapes, making them difficult to process and adapt. PI film and silicone rubber have poor thermal conductivity and uneven heating, leading to problems such as accelerated aging. Therefore, there is an urgent need for a heating component that is both easy to manufacture and has good thermal conductivity. Utility Model Content

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] As a medical device for treating respiratory diseases, ventilators are often designed and used according to actual needs (such as portability, oxygen supply requirements, etc.). This results in certain differences in the structure of ventilators in different scenarios or different models, which requires the heating components to be able to be flexibly adjusted in structure.

[0028] Among related technologies, ceramic heating components have high heating efficiency; however, due to the limitations of the material itself, ceramic heating elements are fragile, difficult to manufacture, and have high processing costs, making them difficult to adapt to the structural adjustments of ventilators. Another type of heating component, PI film and silicone rubber, suffers from poor thermal conductivity and uneven heating due to the materials themselves, leading to heating element aging.

[0029] Regarding the problems in related technologies, such as Figure 1As shown, this embodiment provides an integrated heating assembly 10, including a metal heat-conducting plate 11, a metal pressure plate 12, a heating element 13, and a temperature control module 14. The metal pressure plate 12 is fixedly disposed on the metal heat-conducting plate 11, and a receiving gap is formed between the metal pressure plate 12 and the metal heat-conducting plate 11. The heating element 13 is disposed within the receiving gap. The temperature control module 14 is fixedly connected to the metal heat-conducting plate 11 and electrically connected to the heating element 13. The temperature control module 14 is used to sense the temperature and disconnect the electrical connection with the heating assembly when the temperature is too high. To improve the user experience of the ventilator, a heating element is usually provided in conjunction with the humidifier 30 to provide humidified and warm air. In this embodiment, by setting the heating element 13 between the metal heat-conducting plate 11 and the metal pressure plate 12, the heating efficiency of the heating element 13 can be improved, and the heat can be rapidly and evenly conducted through the metal heat-conducting plate 11, effectively solving the problem of uneven heat distribution. Furthermore, the entire assembly is formed by connecting the metal pressure plate 12 and the metal heat-conducting plate 11, which facilitates overall assembly and improves overall assembly efficiency.

[0030] Specifically, the metal pressure plate 12 has a plate-like structure, and the metal heat-conducting plate 11 has a plate-like structure. A recessed groove 111 is formed within the heat-conducting metal plate for connecting the metal pressure plate 12. The recessed groove 111 can accommodate the metal pressure plate 12, forming an integral structure with the metal heat-conducting plate 11. During connection, the metal pressure plate 12 and the metal heat-conducting plate 11 are connected by a fixing connector. After connection, a receiving gap is formed between the metal pressure plate 12 and the metal heat-conducting plate 11, which is just large enough to accommodate the heating element 13. The heating element 13 is located within the receiving gap and is in contact with both the metal heat-conducting plate 11 and the metal pressure plate 12. The plate-like structure of the metal material enables faster heat conduction, provides good thermal conductivity, and results in a more uniform heat distribution.

[0031] The fixing fastener can be any type of conventional fastener, such as a rivet or screw. The fixing fastener can firmly fix the metal pressure plate 12 to the metal heat-conducting plate 11, so that the heating element 13 is in close contact with the receiving gap, thereby improving the heat transfer rate and achieving a rapid heating response.

[0032] It should be understood that when the temperature is too high as described in the above embodiments, it means that when the temperature exceeds the rated temperature of the temperature control module 14, the electrical connection of the heating element 13 will be disconnected, thereby stopping the heating. For example, the temperature control module 14 is equipped with a thermal protection circuit breaker 141, a temperature control circuit breaker, or a thermal relay. The thermistor in the thermal protection circuit breaker 141, the temperature control circuit breaker, or the thermal relay can disconnect the circuit after sensing overheating.

[0033] In a specific configuration, the heating element 13 is a resistance heating element 13. Resistance heating elements 13 can be manufactured in various styles, improving their flexibility. The heating elements 13 are evenly arranged within the accommodating gap, thereby achieving uniform heating of the metal plate and resulting in better heating uniformity.

[0034] Understandably, ventilators are used to help patients maintain normal respiratory function. In some cold environments, the air provided by the ventilator is cold air, which severely reduces the patient's experience. Therefore, some ventilators incorporate heating components to heat the air and improve the ventilator experience. In this embodiment, the integrated heating assembly 10 uses two metal plates in conjunction with the heating element 13 for heating. The metal material has excellent thermal conductivity, and the heat emitted by the heating element 13 is directly conducted through the metal plates, thereby achieving rapid heating response and better uniform heat conduction. Furthermore, during the heating process, the temperature control module 14 can monitor the temperature in real time and disconnect the heating if the temperature is too high, improving the safety of the device.

[0035] In practical applications, the metal heat-conducting plate 11 and the metal pressure plate 12 are made of the same material, and the opposing surfaces of the metal heat-conducting plate 11 and the metal pressure plate 12 are smooth planes. This allows the heating element 13 to be tightly attached between the two metal plates. The heat generated when the heating element 13 is powered on can be transferred to the metal plate in time, solving the problem of local overheating and aging. The metal plate can also make the heat more uniform.

[0036] Specifically, the metal heat-conducting plate 11 and the metal pressure plate 12 are made of conventional materials with excellent thermal conductivity. For example, they can be made of aluminum, aluminum alloy, copper, copper alloy, or any other material.

[0037] According to the embodiments provided by this utility model, the temperature control module 14 includes a thermal protection circuit breaker 141, a temperature sensor 142, and a transition circuit board 143. Both the thermal protection circuit breaker 141 and the temperature sensor 142 are integrated on the transition circuit board 143, which is fixedly mounted on the metal heat-conducting plate 11. The thermal protection circuit breaker 141 can disconnect the electrical connection with the heating element 13 when the temperature exceeds the rated value. The temperature control module 14 provides overheat protection, enabling heating to stop in case of overheating, preventing safety accidents and improving equipment safety.

[0038] It is understood that the adapter circuit board 143 is a conventional heating control circuit board, on which a heating circuit is installed. The thermal protection circuit breaker 141 and temperature sensor 142 are integrated onto the adapter circuit board 143 and connected to the heating circuit. The temperature sensor 142 is used to sense the temperature of the heating component in real time, while the thermal protection circuit breaker 141 can directly disconnect the heating circuit when the temperature reaches a certain threshold, thereby stopping heating and avoiding safety hazards caused by continuous high temperatures. Overheat protection is achieved through a mechanical linkage mechanism, causing the thermistor inside the protection circuit breaker to deform when the temperature is too high, ultimately triggering the circuit to disconnect and stopping heating.

[0039] Specifically, the thermal protection circuit breaker 141 is installed in the heating circuit as a safety device. Its specific connection circuit is conventional technology in the field, so it will not be described in detail. The thermal protection circuit breaker 141 can provide long-term overheat protection. Specifically, it can protect the circuit by monitoring the heat generated by the current and prevent the equipment from being damaged by overheating.

[0040] In some embodiments, the temperature control module 14 is also electrically connected to a cable 144, which is used for the transmission of electrical energy and information. Correspondingly, a wire hole 113 is provided on one edge of the metal heat-conducting plate 11 for the cable 144 to pass through. The wire hole 113 is used to limit the passage of the cable 144, which makes the cable 144 connection more stable and ensures the overall stability of the device.

[0041] Specifically, cable 144 includes a power cord and an information transmission line. The power cord is used to connect to an external power source to provide power to the entire heating element 13. The information transmission line can feed back temperature information for real-time display on an external display device. That is, the information transmission line is connected to the temperature sensor 142, thereby enabling real-time feedback of the transmitted temperature information.

[0042] According to some embodiments provided by this utility model, a mounting hole 121 is provided on the metal pressure plate 12, and the temperature control module 14 is located in the mounting hole 121. The mounting hole 121 restricts the temperature control module 14 within the mounting hole 121, preventing shaking and improving stability. Moreover, by being located in the mounting hole 121, the temperature of the metal heat-conducting plate 11 and the pressure plate can be directly sensed, allowing for timely detection of temperature changes.

[0043] In some embodiments, the heating element 13 includes a disc-shaped heating element 13 formed by coiling a flat heating wire. The flat heating wire has better temperature resistance, and the disc-shaped heating element 13 can improve the uniformity of heating.

[0044] Specifically, such as Figure 1As shown, the flat heating wire is bent and wound to form a disc-shaped heating element 13. The contact area between the disc-shaped heating element 13 and the metal heat-conducting plate 11 and the pressure plate is higher, which makes the heating uniformity better.

[0045] In a specific configuration, a clearance space 131 is formed within the disc-shaped heating element 13, which is directly opposite the mounting hole 121. This design prevents the heating element 13 from directly facing the temperature control module 14, thus improving overall safety.

[0046] like Figure 1 As shown, the clearance space 131 divides the disc-shaped heating element 13 into two spaced heating sections. The two heating sections can cover most of the area of ​​the first metal clamp and the second metal clamp, while the clearance space 131 avoids direct heating of the temperature control component.

[0047] According to some embodiments provided by this utility model, the resistance of the disc-shaped heating element 13 is 3Ω-24Ω. By limiting the resistance of the disc-shaped heating element 13, it can be adapted to the air heating of a ventilator.

[0048] Specifically, the heating wire is made of a thin metal sheet with high resistivity. The cutting size, length, and bending style of the counting resistor are determined by actual test results, and the optimal power control resistor range is between 3Ω and 24Ω.

[0049] In some specific embodiments, the metal heat-conducting plate 11 is provided with a receiving groove 112, and a part of the body of the thermal protection circuit breaker 141 is located in the receiving groove 112. The thermal protection circuit breaker 141 has a certain thickness, which may cause interference with the metal heat-conducting plate 11 during assembly. In this embodiment, the receiving groove 112 can avoid interference and make the connection of the thermal protection circuit breaker 141 more stable.

[0050] Specifically, the receiving groove 112 is set to correspond to the mounting hole 121. The thermal protection circuit breaker 141 is integrated on the adapter circuit board 143 and is located entirely within the mounting hole 121. This arrangement ensures that when the temperature control module 14 is located within the mounting hole 121, part of the main body of the thermal protection circuit breaker 141 is located within the receiving groove 112, thus achieving a stable connection of the thermal protection circuit breaker 141.

[0051] In some embodiments, both the metal heat-conducting plate 11 and the metal pressure plate 12 have an insulating coating on their surfaces. The insulating coating further improves the safety of the equipment.

[0052] Specifically, when aluminum alloy is used, the surfaces of the metal heat-conducting plate 11 and the metal pressure plate 12 are anodized or hard anodized to achieve surface insulation.

[0053] Understandably, the insulation layer on the two metal plates effectively prevents electrical short circuits and also improves temperature resistance.

[0054] According to some embodiments of this utility model, an anchoring structure 114 is provided on the metal heat-conducting plate 11, and both the pressure plate and the temperature control module 14 are fixed to the metal heat-conducting plate 11 through the anchoring structure 114. The anchoring structure 114 enables the metal pressure plate 12 to be stably connected to the metal heat-conducting plate 11, thereby improving the stability of the connection.

[0055] Specifically, multiple anchoring columns are provided on the bottom surface of the recessed groove 111 of the metal heat-conducting plate 11. The anchoring columns can anchor the pressure plate, so that the pressure plate is fixed on the metal heat-conducting plate 11. With this arrangement, the heating element 13, the pressure plate, and the temperature control module 14 are integrated on the metal heat-conducting plate 11, which facilitates rapid assembly and improves the efficiency of mass production operations.

[0056] The second aspect of this utility model provides a ventilator, such as Figure 2 As shown, the device includes a ventilator body 20 and a humidifier 30, with the ventilator body 20 connected to the humidifier 30. It also includes an integrated heating assembly 10 and a cover 40 as provided in any of the above embodiments. The cover 40 is fixedly disposed at the bottom of a metal heat-conducting plate 11. An installation cavity 21 is provided inside the ventilator body 20, and the metal heat-conducting plate 11 is located within the installation cavity 21. The integrated heating assembly of the ventilator improves its air heating efficiency, and the overall mechanical assembly reduces the overall manufacturing difficulty and cost.

[0057] Specifically, the ventilator body 20 is a conventional ventilator, and an installation cavity 21 is provided on the ventilator body 20. An integrated heating component 10 is located at the bottom of the installation cavity 21, and a metal heat-conducting plate 11 is located inside the installation cavity 21 so as to heat the air inside the installation cavity 21.

[0058] In this embodiment, by installing the integrated heating component 10 within the mounting cavity and enabling rapid heat conduction through the metal heat-conducting plate 11, timely heating of the air is achieved, improving its response speed. Furthermore, the installation cavity 21 ensures a more stable installation connection for the integrated heating component 10, enhancing the overall stability of the equipment.

[0059] Specifically, both the metal heat-conducting plate 11 and the cover 40 have recessed cavity structures on their opposite sides. After the cover 40 is connected to the metal heat-conducting plate 11, it forms a whole heating component and is installed at the bottom of the mounting cavity 21. In the actual connection, the cover 40 is connected to the metal heat-conducting plate 11 by bolts, and a preload spring 50 is provided on the bolts to improve the stability after connection, making the overall structure more stable.

[0060] In a specific embodiment, the bottom surface of the cover 40 is provided with raised support pads 41. The support pads 41 are used to contact the platform or ground when the equipment is placed, providing better support.

[0061] Specifically, such as Figure 2 As shown, the support foot pad 41 has a circular structure. A support foot pad 41 is also provided at the bottom of the suction machine body away from the installation cavity 21, so that they can form a support structure together and provide a good support effect.

[0062] Through the above description of the embodiments, those skilled in the art can clearly understand that the heating components of each embodiment are assembled by mechanical connection, which allows for intuitive observation of the assembly of the heating components. Furthermore, the tools used for assembly are readily available and simple to operate, facilitating rapid mass production and reducing the difficulty and cost of manufacturing. Moreover, the use of metal materials, which possess high hardness and good thermal conductivity, allows the heating element 13 to be sandwiched between two flat metal plates (metal heat-conducting plate 11 and metal pressure plate 12). The flat clamping plates ensure closer contact between the heating wires, and the heat generated when the heating element 13 is energized can be promptly transferred to the metal plates, solving the problem of localized overheating and aging of the heating wires. The metal plates also ensure more uniform heat distribution. Furthermore, all components are processed using modern intelligent processing equipment, allowing the heating plate assembly to be manufactured into various shapes according to requirements, thus adapting to various application equipment and occasions.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
