[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0040] See also Figure 1 and Figure 2The heating body 100 provided in the embodiment of the present application includes a heating element 10, at least two electrodes 20, a protective member 30, an insulating glue 40 and a PCB adapter board 50. The heating element 10 is used to generate heat, and the electrodes 20 are respectively connected to the heating element 10 and the PCB adapter board 50. The protective member 30 and the insulating glue 40 are used to insulate and protect the connection 201 between the electrode 20 and the heating element 10. The PCB adapter board 50 is used to connect the heating element 10 with an external device.

[0041] For the above heating element 10, see Figure 3 and Figure 4 In some embodiments, the heating element 10 includes a support tube 101, a functional layer 102, a flange 103 and a plug 104. The functional layer 102 covers the support tube 101, the functional layer 102 is used to generate heat, the flange 103 is arranged around the functional layer 102, and the flange 103 is used to facilitate the assembly of the heating element 10. The flange 103 can be used for the setting of the protective member 30 in the heating body 100. The plug 104 blocks one of the ports of the support tube 101.

[0042] For the above-mentioned support tube 101, the support tube 101 is used to provide support for the functional layer 102. In some embodiments, the side wall of the support tube 101 is provided with a flow hole 1011, and the flow hole 1011 is used for allowing fluid to flow into and out of the support tube 101. When the functional layer 102 is coated on the support tube 101, the flow hole 1011 is exposed to facilitate the inflow and outflow of the fluid.

[0043] It is worth noting that the support tube 101 has a first end and a second end that are arranged opposite to each other. The first end of the support tube 101 is arranged close to the electrode 20. The port at the first end of the support tube 101 is used for the plug 104 to be arranged, and the port at the second end of the support tube 101 is used for the fluid to flow into and out of the support tube 101. That is, the second end of the support tube 101 and the flow hole 1011 form an opening for the fluid to flow into and out of the support tube 101. For example, the flow hole 1011 is used for the fluid to flow into the support tube 101, and the port at the second end of the support tube 101 is used for the fluid to flow out of the support tube 101. Alternatively, the flow hole 1011 is used for the fluid to flow into the support tube 101, and the port at the second end of the support tube 101 is used for the fluid to flow out of the support tube 101.

[0044] It is worth noting that one of the functions of the support tube 101 is to transfer the heat generated by the functional layer 102 to the fluid in the support tube 101, so when selecting the material of the support tube 101, the thermal conductivity of the material needs to be considered. In some embodiments, the support tube 101 is a ceramic tube, which has high thermal conductivity, fast fluid heating speed, and high efficiency of the heating body 100; in addition, due to the high flexural strength of the ceramic tube, the service life of the heating body 100 is long. In some other embodiments, the support tube 101 is an alumina ceramic tube, or a zirconia ceramic tube, or the support tube 101 is an alumina and zirconia composite ceramic tube.

[0045] Regarding the above-mentioned functional layer 102, the functional layer 102 is used to generate heat. In some embodiments, the functional layer 102 only provides a heating function, and the functional layer 102 can be a heating layer (not shown) formed by coating a heating slurry (not shown) on the support tube 101. The functional layer 102 can also be a heating layer (not shown) formed by winding a heating wire (not shown) on the support tube 101.

[0046] In some embodiments, the functional layer 102 not only has the function of generating heat, but also can detect the temperature at the same time, so that the functional layer 102 can be a two-layer structure including a heating layer (not shown) and a temperature-sensitive layer (not shown), and the heating layer and the temperature-sensitive layer are both coated on the support tube 101, and the heating layer is located between the support tube 101 and the temperature-sensitive layer, or the temperature-sensitive layer is located between the support tube 101 and the heating layer. Among them, the heating layer is used to generate heat, and the temperature-sensitive layer is used to detect the temperature. Among them, the temperature-sensitive layer can be formed by coating a temperature-sensitive slurry (not shown), or it can be formed by winding a metal wire (not shown). The metal wire senses temperature changes, and its resistance value also changes accordingly, so that the temperature can be detected, which is convenient for controlling the temperature.

[0047] In addition, when the functional layer 102 has both the function of generating heat and the function of detecting temperature, the functional layer 102 can also be a one-layer structure, that is, a composite layer with the function of heating and detecting temperature. For example, the functional layer 102 includes a heating wire (not shown) and a temperature-sensitive paste (not shown), and the temperature-sensitive paste covers the heating wire. When the heating wire is energized, the heating wire generates heat. On the one hand, it can heat the fluid flowing through the support tube 101. On the other hand, the temperature-sensitive paste senses the temperature change, so that the temperature can be detected, which is convenient for controlling the temperature. For another example, the functional layer 102 includes a metal wire and a heating paste, and the heating paste covers the metal wire. When the heating paste is energized, the heating paste generates heat. On the one hand, it can heat the fluid flowing through the support tube 101. On the other hand, the metal wire senses the temperature change, and its resistance value also changes accordingly, so that the temperature can be detected, which is convenient for controlling the temperature.

[0048] It is worth noting that the functional layer 102 is used to be connected to the at least two electrodes 20 , thereby connecting to an external power source to achieve the heat generation function of the functional layer 102 .

[0049] For the plug 104, one end of the plug 104 blocks the port of the first end of the support tube 101, thereby forming a dry area at the first end of the support tube 101, so as to facilitate the connection of the electrode 20. The other end of the plug 104 is arranged to protrude from the first end of the support tube 101. Since the plug 104 blocks the first end of the support tube 101, that is, there is no fluid at the position where one end of the plug 104 is located in the support tube 101, it is not necessary to heat the place. Therefore, in some embodiments, the first end of the support tube 101 is arranged to protrude from the functional layer 102, that is, there is a blank area of ​​the functional layer 102 at the first end of the support tube 101, so that the functional layer 102 is not wasted, saving costs.

[0050] It is worth noting that, in some embodiments, the other end of the plug 104 is protruding from the first end of the support tube 101, and an isolating member 1041 is radially extended from the other end of the plug 104, and the isolating member 1041 is bent toward one end of the plug 104 and extends between the first end of the support tube 101 and the electrode 20. The isolating member 1041 provides support for the electrode 20, thereby reducing the risk of damage to the electrode 20.

[0051] For the above electrode 20, see Figure 4 The number of electrodes 20 is at least two, so that an external power source can supply power to the heating element 10 to realize the heat generation function of the heating element 10.

[0052] One end of the electrode 20 has a connection portion 201, and the connection portion 201 is connected to the heating element 10. When the heating element 10 includes the functional layer 102, the connection portion 201 is connected to the functional layer 102. The other end of the electrode 20 is used to connect to an external device.

[0053] It is worth noting that, since the functional layer 102 may include a heating layer having only a heating function, the number of the electrodes 20 may be two. Since the functional layer 102 may also include a heating layer having a heating function and a temperature sensing layer having a temperature sensing function, not only the heating layer needs to be connected to an external device, but the temperature sensing layer also needs to be connected to an external device, and the number of the electrodes 20 needs to be 4. When the number of heating layers is multiple, the number of the corresponding electrodes 20 will also increase.

[0054] It is worth noting that in some embodiments, the electrode 20 is a conductive sheet, specifically, a conductive copper sheet. When the electrode 20 is a conductive sheet, the connection 201 of the electrode 20 is larger than the wire, so the connection between the electrode 20 and the heating element 10 is tight, and it is not easy for the electrode 20 to be separated from the heating element 10.

[0055] For the above-mentioned protective member 30 and insulating adhesive 40, please refer to Figure 4 The protective member 30 is provided with a protective groove 301, and the end of the heating element 10 away from the electrode 20 passes through the bottom of the protective groove 301, so that the connection 201 of the electrode 20 is accommodated in the protective groove 301, and the through-hole 1011 of the heating element 10 is located between the protective member 30 and the end of the heating element 10 away from the electrode 20. The insulating glue 40 is filled in the protective groove 301, and the insulating glue 40 covers the connection 201. Specifically, the insulating glue 40 can be covered between the connection 201 and the groove wall of the protective groove 301, so that when the insulating glue 40 is used to fill the protective groove 301 to insulate and isolate the connection 201, due to the constraint of the protective member 30, it is convenient for the operator to use the insulating glue 40 to control the insulation effect of the connection 201, and while improving the operator's use experience, the insulation reliability of the connection 201 is improved, and the use safety of the heating element 10 is improved.

[0056] In some embodiments, the insulating glue 40 includes a potting glue, so that the protective groove 301 is filled with the potting glue, and the potting glue flows in the protective groove 301 by utilizing the fluidity of the potting glue, so as to cover the connection 201. In addition, after curing, the potting glue can also fix and protect one end of the electrode 20 and the connection 201 of the electrode 20, thereby improving the connection reliability between the electrode 20 and the heating element 10.

[0057] In some embodiments, the insulating glue 40 extends from the bottom of the protective groove 301 to the notch of the protective groove 301 , thereby enhancing the insulating effect of the insulating glue 40 on one end of the electrode 20 and the connection 201 of the electrode 20 .

[0058] In some embodiments, the protective member 30 extends a positioning boss 302 in a direction away from the heating element 10 , and the positioning boss 302 is used to install the heating body 100 on an external device.

[0059] It is worth noting that, in some embodiments, the positioning boss 302 is disposed on the heating element 10 , for example, the positioning boss 302 is formed by the flange 103 extending in a direction away from the support tube 101 .

[0060] It is worth noting that, in some embodiments, see Figure 1Along the circumference of the support tube 101 , an arc angle θ of the arc formed between the positioning boss 302 and the flow hole 1011 has a preset value.

[0061] In some embodiments, the preset value includes 0 degrees, 90 degrees, 180 degrees and 270 degrees. Through this setting, the preset value facilitates the operator to install the heating body 100 through the positioning boss 302, and facilitates the inflow and outflow of the flow hole 1011 to connect the fluid.

[0062] It is worth noting that, in some embodiments, see Figure 1 A receiving groove 3011 extends from the groove wall of the protection groove 301 in a direction away from the protection groove 301, and the insulating glue 40 is filled in the receiving groove 3011. The number of the receiving grooves 3011 is the same as the number of the electrodes 20. One receiving groove 3011 is used to accommodate one electrode 20, which not only facilitates the insulation protection of the connection 201 of the electrode 20, but also saves the use of the insulating glue 40.

[0063] It is understandable that the other end of the electrode 20 extends out of the insulating glue 40 to be connected to an external device.

[0064] It is worth noting that when the heating body 100 includes the above-mentioned heating element 10, at least two electrodes 20, a protective member 30 and an insulating glue 40, one end of the electrode 20 has a connection 201, the connection 201 is connected to the heating element 10, and the other end of the electrode 20 is used to connect to an external device; the protective member 30 is provided with a protective groove 301, and the end of the heating element 10 away from the electrode 20 passes through the bottom of the protective groove 301 so that the connection 201 is accommodated in the protective groove 301; the insulating glue 40 is filled in the protective groove 301, and the insulating glue 40 covers the connection 201. Through the heating body 100, the protective member 30 is sleeved on the outside of the heating element 10, and the connection 201 between one end of the electrode 20 and the heating element 10 is set in the protective groove 301 of the protective member 30. Therefore, when the insulating glue 40 is used to fill the protective groove 301 to insulate the connection 201, due to the constraint of the protective member 30, it is convenient for the operator to use the insulating glue 40 to control the insulation effect of the connection 201. While improving the operator's use experience, the insulation reliability of the connection 201 is improved, and the use safety of the heating element 10 is improved.

[0065] For the above PCB adapter plate 50, please also refer to Figure 2 and Figure 5, the PCB adapter board 50 is used for connecting the heating element 10 with an external device through the electrode 20. Specifically, the PCB adapter board 50 is provided with at least two conductive holes 501, and the PCB adapter board 50 is used to connect with an external device; one end of the electrode 20 is connected to the heating element 10, and the other end of the electrode 20 is passed through the conductive hole 501, and one electrode 20 is passed through one conductive hole 501. Through the above-mentioned heating body 100, it is convenient to connect the heating element 10 with an external device to heat the device.

[0066] It can be understood that, in some embodiments, the number of the conductive holes 501 is the same as the number of the electrodes 20 .

[0067] It can be understood that when the electrode 20 is a conductive sheet, the other end of the electrode 20 can be plugged into the conductive hole 501, thereby not only strengthening the connection between the electrode 20 and the heating element 10, reducing the wind direction of the electrode 20 and the heating element 10 being separated, but also facilitating the other end of the electrode 20 to pass through the conductive hole 501 and be installed in the PCB adapter board 50.

[0068] The PCB adapter 50 is a printed circuit board adapter (PCB Adapter), which can provide interfaces or connection points to realize electrical connection and signal transmission between different components.

[0069] It is worth noting that, in some embodiments, the PCB adapter board 50 is provided with at least two adapter wires 502 and at least two adapter parts 503, the number of the adapter parts 503 is the same as the number of the adapter wires 502, one adapter part 503 corresponds to one adapter wire 502, the adapter wire 502 is used to connect the external device, one end of the adapter part 503 is connected to the adapter wire 502, and the other end of the adapter part 503 is detachably connected to the PCB adapter board 50. Through this setting, when the heating element 10 is used to heat the device, it can be directly connected through the adapter wire 502 connected to the adapter part 503, and there is no need to weld wires to the heating element 10, so the installation is more convenient and quick.

[0070] It is worth noting that the adapter cable 502 includes a power line 5021 for supplying power to the heating element 10 .

[0071] In some embodiments, the adapter cable 502 includes a signal line 5022 for controlling the heating element 10 .

[0072] In some embodiments, the other end of the adapter 503 is detachably connected to the PCB adapter plate 50 via fasteners (such as screws, bolts, etc.).

[0073] It is worth noting that, through the PCB adapter board 50 , multiple heating elements 10 can be simultaneously connected to the same PCB adapter board 50 , thereby enhancing the heating effect of the heating body 100 on the fluid and expanding the application range of the heating body 100 .

[0074] When there are multiple heating elements 10 , one heating element 10 is connected to the PCB adapter board 50 via at least two electrodes 20 and at least two conductive holes 501 .

[0075] It is worth noting that when the number of the heating elements 10 is multiple, in some embodiments, the heating body 100 also includes a fixing member 60, and the fixing member 60 is provided with multiple fixing holes (not shown in the figure), and the heating element 10 is arranged on the fixing member 60 at the fixing holes, and one heating element 10 corresponds to one fixing hole.

[0076] It can be understood that the number of the fixing holes is the same as the number of the heating elements 10 .

[0077] It is worth noting that when the heating element 10 includes a support tube 101, a functional layer 102, a flange 103 and a plug 104, the support tube 101 and the functional layer 102 pass through the fixing hole, and the flange 103 abuts against the fixing member 60. In some embodiments, the flange 103 and the fixing member 60 are sealed.

[0078] It is worth noting that, in some embodiments, the fixing member 60 is elastic, for example, the fixing member 60 is made of rubber or foam, so that the heating element 10 is conveniently arranged on the fixing member 60 at the fixing hole.

[0079] It is worth noting that, in some embodiments, the fixing member 60 is provided with a positioning groove 601, and the notch of the positioning groove 601 is connected to the fixing hole; the heating element 10 is provided with a positioning boss 302, and the positioning boss 302 is used to be clamped in the positioning groove 601, so as to facilitate the assembly between the heating element 10 and the fixing member 60.

[0080] It is understandable that when there are multiple heating elements 10, there are multiple fixing holes, and there are multiple positioning grooves 601, and the number of heating elements 10, the number of fixing holes, and the number of positioning grooves 601 are the same. The positioning boss 302 of one heating element 10 is used to be clamped in one positioning groove 601.

[0081] It is worth noting that, in some embodiments, the heating body 100 further includes a support member 70, which is disposed on the fixing member 60 and is provided with a plurality of receiving grooves 701; the end of the heating element 10 away from the electrode 20 passes through the bottom of the receiving groove 701 and the fixing hole in sequence and is then disposed on the fixing member 60; one heating element 10 corresponds to one receiving groove 701; the end of the heating element 10 close to the electrode 20 is received in the receiving groove 701, and one end of the electrode 20 is received in the receiving groove 701; the PCB adapter plate 50 is covered with a notch of the receiving groove 701, and one receiving groove 701 corresponds to at least two conductive holes 501. The support member 70 can provide support to the PCB adapter plate 50 on the one hand, and can support the portion of the electrode 20 extending out of the heating element 10 and passing through the conductive holes 501 on the other hand, so that the electrode 20 is not easily bent or damaged.

[0082] It is worth noting that, in some embodiments, the support member 70 is provided with a limiting column 702, and the PCB adapter plate 50 is provided with a limiting hole 504. The limiting column 702 is used to be set in the limiting hole 504, so that the PCB adapter plate 50 is conveniently stacked on the support member 70 through the limiting column 702 and the limiting hole 504, and in the process of facilitating the PCB adapter plate 50 to be stacked on the support member 70, the other end of the electrode 20 is passed through the conductive hole 501.

[0083] It is understandable that the number of the limiting columns 702 can be multiple, the number of the limiting holes 504 can be multiple, the number of the limiting columns 702 is the same as the number of the limiting holes 504, and one limiting column 702 is used to be set in one limiting hole 504.

[0084] It is worth noting that when the heating body 100 includes a heating element 10, at least two electrodes 20 and a PCB adapter board 50, the PCB adapter board 50 is provided with at least two conductive holes 501, and the PCB adapter board 50 is used to connect with an external device; one end of the electrode 20 is connected to the heating element 10, and the other end of the electrode 20 is passed through the conductive hole 501, and one of the electrodes 20 is passed through the conductive hole 501. Since the heating element 10 is connected to the PCB adapter board 50 through the electrode 20, and the PCB adapter board 50 is used to connect with an external device, when the heating element 10 is used to heat the device, it is no longer necessary to weld the wire to the heating element 10, and the heating body 100 provided in the embodiment of the present application is used to heat the device, so the installation is convenient and easy. When there are multiple heating elements 10, the multiple heating elements 10 can be connected to the same PCB adapter board 50, and then connected to external devices through the PCB terminal board. Compared with the method of separately welding wires to each heating element 10 in the prior art, the heating body 100 provided in the embodiment of the present application is convenient for wiring, which overcomes the wiring confusion that is easily caused by separately wiring multiple heating elements 10 in the prior art, and provides a good user experience.

[0085] The present application also provides an embodiment of a heater 200, see Figure 6 and Figure 7 The heater 200 includes a cavity 80 and the heating body 100. The heating body 100 is accommodated in the cavity 80 and is used to generate heat. Through the heater 200, when it is necessary to heat the device, it is only necessary to connect the heater 200 to the device, and it is not necessary to assemble from the heating body 100, thereby saving the assembly process of the heater 200 and the device to be heated. For the specific structure and function of the heating body 100, please refer to the above embodiment, which will not be repeated here.

[0086] In addition, in some embodiments, the heater 200 also includes a sealing ring 90, which is disposed between the cavity 80 and the heating body 100. Specifically, the sealing ring 90 can be disposed between the cavity 80 and the fixing member 60, thereby isolating water vapor at one end of the heating element 10 away from the electrode 20 from entering the end where the electrode 20 is located and affecting the wiring.
