Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples without contradiction.

[0027] The breathing machine as a medical instrument for treating respiratory diseases often designs and uses the structure according to the actual demand (for example, the portable demand, the oxygen supply amount demand and the like), which makes the structure of the breathing machine in different scenes or different use types have certain differences, which requires that the heating assembly can have flexible structure adjustment.

[0028] In the related art, the ceramic heating assembly has high heating efficiency, but the ceramic heating element is limited by its own material, which is easy to break and difficult to prepare, and the processing cost is high, which is difficult to adapt to the structure adjustment of the breathing machine. Another type of PI film and silicone rubber heating assembly has poor heat conduction performance due to its own material, and is not heated uniformly, so that the heating element will be heated and aged.

[0029] In view of the problems in the related art, such as Figure 1As shown, the present example provides a heating assembly 10 of a breathing machine, comprising a first metal clamp plate 11, a second metal clamp plate 12, a heating element 13 and a temperature control assembly 14; the first metal clamp plate 11 and the second metal clamp plate 12 are connected by a fastener and form an accommodation gap between the first metal clamp plate 11 and the second metal clamp plate 12, and the heating element 13 is arranged in the accommodation gap; the temperature control assembly 14 is arranged on the first metal clamp plate 11, and a heating circuit is arranged in the temperature control assembly 14 to input electric energy through the heating circuit; the temperature control assembly 14 is electrically connected with the heating element 13, and the temperature control assembly 14 is used for detecting the heating temperature and disconnecting the heating circuit when the temperature is too high. In order to improve the use experience of the breathing machine, the heating assembly 10 is usually arranged in cooperation with a humidifier 30 to provide air that is humidified and has a temperature. In the present embodiment, the heating element 13 is clamped between the two metal plates to improve the heating efficiency of the heating assembly 10, and the whole is connected by a mechanical assembly method, which is easy to assemble and can improve the assembly efficiency.

[0030] Specifically, the first metal clamp plate 11 and the second metal clamp plate 12 are both plate-shaped structures, and a connecting hole is arranged on each of the first metal clamp plate 11 and the second metal clamp plate 12. The fastener connects the two metal clamp plates together through the connecting hole, and forms an accommodation gap between the first metal clamp plate 11 and the second metal clamp plate 12, which can just accommodate the heating element 13. The heating element 13 is arranged in the accommodation gap. The metal plate can realize faster heat conduction, has good heat conduction performance, and the heat conduction is more uniform.

[0031] The fastener can be any of existing fasteners, such as a rivet, a screw, etc. The connection of the fastener can only press the heating element 13 between the first metal clamp plate 11 and the second metal clamp plate 12, so that the heating element 13 is attached to the metal plate, thereby further improving the heat transfer rate and realizing fast response of heating.

[0032] Further, when the temperature is too high in the above-mentioned embodiment, the heating circuit will be disconnected when the temperature exceeds the bearing range of the temperature control assembly 14.

[0033] Specifically, the heating element 13 is a resistive heating element 13, which can be prepared in multiple styles to improve its flexibility. The heating element 13 is uniformly arranged in the accommodation gap, thereby realizing uniform heating of the metal plate and better uniformity of heating.

[0034] It can be understood that the breathing machine is used to help the patient maintain normal respiratory function, and in some cold environment, the air provided by the breathing machine is cold air, which seriously reduces the use experience of the patient, so a heating assembly 10 is added in some breathing machines to heat the air and improve the experience of the breathing machine. In the embodiment, the heating assembly 10 is heated by two metal plates cooperating with the heating piece 13. The metal material has excellent heat conduction performance, and the heat emitted by the heating piece 13 is directly conducted through the metal plate, so that the rapid response of heating can be realized, and the uniformity of heat conduction is better. Further, the temperature control assembly 14 can be used to monitor the temperature in real time during heating, and the heating can be turned off when the temperature is too high, thereby improving the safety of the equipment.

[0035] In specific application, the first metal clamping plate 11 and the second metal clamping plate 12 adopt the same material, and the opposite surfaces of the first metal clamping plate 11 and the second metal clamping plate 12 are smooth planes, which makes the heating piece 13 tightly adhere to the two metal clamping plates. The heat generated by the heating piece 13 can be transmitted to the metal clamping plate in time, solving the problem of local overheating and aging. The metal clamping plate can also make the heat more uniform.

[0036] Specifically, the first metal clamping plate 11 and the second metal clamping plate 12 adopt a material with excellent conventional heat conduction performance. For example, any one of aluminum, aluminum alloy, copper, copper alloy, etc. can be used.

[0037] According to the embodiment of the utility model, the temperature control assembly 14 includes a thermal circuit breaker 141, a temperature sensor 142 and a switching circuit board 143, the thermal circuit breaker 141 and the temperature sensor 142 are connected with the switching circuit board 143, the switching circuit board 143 is arranged on the first metal clamping plate 11, and the heating piece 13 is electrically connected with the switching circuit board 143. The temperature control assembly 14 is used to disconnect the heating circuit and stop heating when the temperature of the heating assembly 10 is too high, so as to avoid safety accidents and improve the safety of the equipment.

[0038] It can be understood that the switching circuit board 143 is a conventional heating control circuit board, and the heating circuit is arranged on the heating control circuit board, and the thermal circuit breaker 141 and the temperature sensor 142 are integrated on the switching circuit board 143 and connected with the heating circuit. The temperature sensor 142 is used to detect the temperature of the heating assembly 10 in real time, and the thermal circuit breaker 141 can directly disconnect the heating circuit when the temperature reaches a certain threshold value, so as to stop heating and avoid the safety hazard caused by continuous high temperature.

[0039] Specifically, the thermal cut-out 141 is arranged in the heating circuit as a safety device, and the specific connection circuit is a conventional technology in the art, and thus will not be described in detail. The thermal cut-out 141 can provide long-term overload protection, and can protect the circuit by monitoring the heat generated by the current, thereby preventing the equipment from being damaged by overload.

[0040] Specifically, the power supply line and the information transmission line are further arranged on the adapter circuit board 143. The power supply line is used to be connected with an external power supply to provide power for the entire heating assembly 10, and the information transmission line can feed back temperature information for real-time display by an external display device. That is, the information transmission line is connected with the temperature sensor 142, so that the temperature information can be fed back and transmitted in real time.

[0041] According to some embodiments of the present application, the first metal clamping plate 11 is provided with a mounting hole 111, and the temperature control assembly 14 is arranged in the mounting hole 111. The mounting hole 111 allows the temperature control assembly 14 to be directly arranged on the metal clamping plate, so that the temperature change can be quickly sensed and detected in time.

[0042] Specifically, as shown in Figure 1 the mounting hole 111 is arranged in the middle of the first metal clamping plate 11, and a matching hole 121 is arranged on the second metal clamping plate 12. During installation, the thermal cut-out 141 is relatively thick, and thus the matching hole 121 is arranged to avoid interference with the second metal clamping plate 12 during installation of the temperature control assembly 14. The shape of the mounting hole 111 is the same as the overall shape of the temperature control assembly 14, which facilitates installation of the temperature control assembly 14 and improves the stability of the device.

[0043] It can be understood that the temperature control assembly 14 is arranged in the mounting hole 111 during installation, which can limit the shaking of the temperature assembly, so that the stability of the temperature control assembly 14 is higher.

[0044] In some embodiments, the heating element 13 includes a disc-shaped heating element 13 wound by a flat heating wire. The flat heating wire has better temperature resistance, and the disc-shaped heating element 13 can improve the uniformity of heat generation.

[0045] Specifically, as shown in Figure 1 the flat heating wire is wound by bending to form the disc-shaped heating element 13, and the contact area between the disc-shaped heating element 13 and the first metal clamping plate 11 and the second metal clamping plate 12 is higher, which makes the heating uniformity better.

[0046] In some specific embodiments, the disc-shaped heating element 13 is formed with a clearance space 131 opposite the mounting hole 111. In this way, the heating element 13 can be prevented from directly facing the temperature control assembly 14, thereby improving the overall safety.

[0047] As shown in Figure 1 The clearance space 131 divides the disc-shaped heating element 13 into two spaced-apart heating portions, which can cover most of the first metal clamping plate 11 and the second metal clamping plate 12. The clearance space 131 avoids directly heating the temperature control assembly 14.

[0048] According to some embodiments of the present application, the resistance of the heating element 13 is 3Ω-24Ω. By limiting the resistance of the heating element 13, it can be adapted to the air heating of the breathing machine.

[0049] Specifically, the heating wire is cut from a metal material with high resistivity, and the cutting size, length and bending pattern of the resistance are counted. According to actual test, the required power control resistance range is between 3Ω-24Ω, which is the best.

[0050] In some embodiments, the surfaces of the first metal clamping plate 11 and the second metal clamping plate 12 are provided with an insulating coating. The insulating coating can further improve the safety of the heating assembly 10.

[0051] Specifically, when an aluminum alloy material is used, the surfaces of the first metal clamping plate 11 and the second metal clamping plate 12 are anodized or hard anodized, thereby realizing surface insulation.

[0052] It can be understood that the two metal clamping plates can effectively prevent electrical short circuiting by the insulating layer, and can also improve the temperature resistance.

[0053] As shown in Figure 2 The second aspect of the present application provides a breathing machine, which comprises a breathing machine body 20 and a humidifier 30. The breathing machine body 20 is connected to the humidifier 30. The breathing machine further comprises a heat conduction assembly 40, which is formed with a mounting chamber. The mounting chamber is provided with the heating assembly 10 of the breathing machine according to any one of the above embodiments. By providing the heating assembly 10 of the breathing machine, the air heating efficiency of the breathing machine can be improved, and the overall preparation difficulty and cost can be reduced.

[0054] Specifically, the breathing machine body 20 is a conventional breathing machine. The breathing machine body 20 is provided with a cavity 21. The heat conduction assembly 40 is arranged at the bottom of the cavity 21, so as to heat the air in the cavity 21.

[0055] In this embodiment, by installing the heating component 10 within the installation chamber and enabling rapid heat conduction through the heat-conducting component 40, timely heating of the air is achieved, improving its response speed. Furthermore, the installation cavity 21 ensures a more stable connection for the heating component 10, enhancing the overall stability of the device.

[0056] According to the embodiments provided by this utility model, the heat-conducting assembly 40 includes a heat-conducting plate 41 and a cover 42. The cover 42 is connected to the heat-conducting plate 41, and the heat-conducting plate 41 is located above the cover 42 to form an installation chamber. The connection between the cover 42 and the heat-conducting plate 41 facilitates rapid assembly and improves the efficiency of mass production.

[0057] Specifically, the heat-conducting plate 41 and the cover 42 have a recessed cavity structure on their opposite sides. After the cover 42 is connected to the heat-conducting plate 41, its cavity structure forms an installation chamber. In the actual connection, the cover 42 is connected to the heat-conducting plate 41 by bolts, and a preload spring 43 is provided on the bolts to improve the stability of the heat-conducting assembly 40 after connection, making the overall structure more stable.

[0058] In a specific embodiment, a raised support foot pad 421 is provided on the bottom surface of the cover 42. The support foot pad 421 is used to contact the platform or ground when the equipment is placed, providing better support.

[0059] Specifically, such as Figure 2 As shown, the support foot pad 421 has a circular structure. A support foot pad 421 is also provided at the bottom of the suction machine body away from the heating component 10, so that they can form a support structure together and provide a good support effect.

[0060] Through the above description of the embodiments, those skilled in the art can clearly understand that the heating components 10 in each embodiment are assembled by mechanical connection. This allows for direct observation of the assembly of the heating components 10, and the tools used for assembly are readily available and simple to operate, facilitating rapid mass production and reducing manufacturing difficulty and cost. Furthermore, the use of metal materials, which possess high hardness and good thermal conductivity, allows for closer contact between the heating element 13 and the heating wire. The heat generated when the heating element 13 is energized can be promptly transferred to the metal clamps, solving the problem of localized overheating and aging of the heating wire. The metal clamps also ensure more uniform heat distribution. Moreover, all components are processed using modern intelligent processing equipment, allowing the heating plate assembly to be manufactured into various shapes to suit different applications and occasions.

[0061] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still be modified to the technical solutions recorded in the foregoing examples, or part of the technical features are replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
