[0002] Heaters are electrical appliances that use electrical energy to achieve heating effects. They are small in size and have high heating power, so heaters are widely used, such as in smart bathrooms, new energy vehicles, energy storage and other fields. The heater transfers the heat generated by the ceramic tube to the liquid, which then transfers it to various locations of the main device to provide warm water for the device or heat other components.

[0003] However, the ceramic tube of the heater in the prior art is completely immersed in the liquid in the flow channel of the shell. Since the ceramic tube is in direct contact with the liquid, when the heat on the ceramic tube is directly transferred to the liquid in the flow channel, when there is a steam-water mixture in the flow channel cavity, the steam-water mixture contacts the ceramic tube of the heater, causing the temperature of the contact area to rise rapidly, thereby causing the heater to break. Since the heater is in direct contact with the liquid without insulation measures, the heater will have leakage problems after breaking. Summary of the invention

[0025] The present application provides a heating device. Figure 1 As shown, the heating device of this embodiment includes: a box body 10 and a heating component 20, a receiving portion 101 is formed in the box body 10, at least part of the heating component 20 is arranged in the receiving portion 101, the heating component 20 includes a shell 201 and a heating portion 202 arranged inside the shell 201, the shell 201 cooperates with the box body 10 to form a flow channel 30, and the heating portion 202 heats the liquid in the flow channel 30 through the shell 201. Among them, the shell 201 is inserted into the receiving portion 101 of the box body 10, so that the shell 201 and the box body 10 form a flow channel 30, when the liquid in the flow channel 30 is heated, the heating portion 202 heats the shell 201 to provide heat, and the heat of the shell 201 is transmitted to the liquid in the flow channel 30, thereby heating the liquid. The heating portion 202 is externally connected to an external power supply, and when the heating portion 202 needs to be heated, the external power supply provides the required voltage to the heating portion 202.

[0026] In an optional embodiment, a receiving portion 101 is formed in the box body 10, and the heating component 20 can be inserted into the receiving portion 101 of the box body 10. In order to prevent the liquid in the flow channel 30 from directly contacting the heating portion 202, the heating component 20 includes a shell 201 and a heating portion 202. The heating portion 202 is inserted in the shell 201, and the shell 201 is then inserted in the box body 10, so that the flow channel 30 is formed through the shell 201 and the box body 10, so that the heating portion 202 is separated from the liquid in the flow channel 30 through the shell 201. After the heating portion 202 is broken, the heating portion 202 is prevented from directly contacting the liquid, so that the heating portion 202 and the liquid are electrically conductive, and the situation of leakage when the heating portion 202 is broken is avoided, thereby improving the safety of the heating component 20. Specifically, when the liquid inside the flow channel 30 is heated, the liquid can be passed into the flow channel 30 formed by the outer shell 201 and the box body 10, and the heating part 202 is heated by an external power supply. The heat of the heating part 202 is transferred to the side wall of the outer shell 201 inserted in the box body 10, so that the heat is transferred to the liquid in the flow channel 30 through the outer shell 201, thereby completing the heating of the liquid.

[0027] In this embodiment, combined with Figure 5 As shown, when installing the heating device, the heating part 202 is plugged into the shell 201, and then the shell 201 is plugged into the box 10, thereby completing the assembly of the heating device. The liquid in the flow channel 30 formed by the shell 201 and the box 10 heats the shell 201 through the heating part 202, so that the heat is transferred to the liquid in the flow channel 30 through the shell 201. That is, the shell 201 provides heat to the liquid in the flow channel 30, thereby heating the liquid in the flow channel 30, and the shell 201 separates the heating part 202 and the liquid in the flow channel 30, thereby avoiding the leakage of the heating device after the heating part 202 breaks, and effectively improving the safety of the heating device. When installing the heating part 202, the heating part 202 is directly plugged into the shell 201, and the shell 201 is plugged into the box 10, thereby simplifying the step of assembling the heating component 20 in the accommodating portion 101. When the heating part 202 needs to be replaced, the heating part 202 can be directly taken out from the housing 201 without using other tools to disassemble the heating part 202 .

[0028] In the above embodiment, a receiving portion 101 is formed in the housing 10, and the heating component 20 is inserted into the housing 10. The heating component 20 includes a shell 201 and a heating portion 202. The shell 201 cooperates with the housing 10 to form a flow channel 30. The shell 201 separates the heating portion 202 from the liquid in the flow channel 30. The heating portion 202 is inserted into the shell 201, which simplifies the assembly steps of the heating portion 202. The shell 201 prevents the heating portion 202 from contacting the liquid in the flow channel 30, prevents the heating portion 202 from breaking and causing leakage of the heating device, and effectively improves the safety of the heating device.

[0029] In an optional embodiment, if Figure 2 As shown, the shell 201 includes a flat portion 203 and a raised portion 204, a plurality of raised portions 204 are provided, one end of the raised portion 204 is connected to the flat portion 203, the raised portion 204 forms a accommodating space 205, the opening of the accommodating space 205 is located at one end where the raised portion 204 is connected to the flat portion 203, the raised portion 204 is located in the accommodating portion 101, and the heating portion 202 is arranged in the accommodating space 205. The outer shell 201 is provided with a flat portion 203 and a protruding portion 204. When the outer shell 201 is inserted into the box body 10, the protruding portion 204 and the flat portion 203 cooperate with the box body 10, so that a flow channel 30 is formed by the protruding portion 204, the flat portion 203 and the box body 10. The flat portion 203 is arranged perpendicular to the protruding portion 204 of the outer shell 201, and the protruding portion 204 is perpendicular to the bottom side wall of the box body 10, so that the side wall of the protruding portion 204 is located in the flow channel 30, and the liquid in the flow channel 30 contacts the side wall of the protruding portion 204, so that heat is provided to the liquid in the flow channel 30 through the protruding portion 204. Specifically, the raised portion 204 is connected to the flat portion 203, and an accommodating space 205 is formed in the raised portion 204. The heating portion 202 is inserted into the raised portion 204. When the heating portion 202 is heated, the heat can be transferred to the side wall of the raised portion 204, and the heat can be transferred to the liquid in the flow channel 30 through the side wall of the raised portion 204.

[0030] In this embodiment, the opening of the accommodation space 205 of the protrusion 204 is located at one end where the protrusion 204 is connected to the flat plate 203, the protrusion 204 is located in the accommodation portion 101 of the box 10, and the heating portion 202 is located in the accommodation space 205 of the protrusion 204. When installing the heating device, the heating portion 202 can be inserted into the accommodation space 205 of the protrusion 204 through the opening of the accommodation space 205. When adding liquid, the liquid can be passed into the flow channel 30 formed by the flat plate 203, the protrusion 204 and the box 10, and the heating portion 202 can be connected to an external power supply, so as to start the heating portion 202 so that the heating portion 202 starts to heat, and the heat of the heating portion 202 is transmitted to the side wall of the protrusion. Since the protrusion 204 is inserted into the interior of the box 10, the outer side wall of the protrusion 204 contacts the liquid, thereby providing heat to the liquid in the flow channel 30 through the side wall of the protrusion 204.

[0031] In an optional embodiment, the heating part 202 and the protrusion 204 are configured as sheets. That is, the heating part 202 and the protrusion 204 are configured as sheet structures, so that when the protrusion 204 of the housing 201 is inserted into the box body 10 and the liquid in the flow channel 30 is heated by the protrusion 204, the volume occupied by the protrusion 204 in the box body 10 can be effectively reduced, thereby increasing the contact area between the liquid and the heating component 20. Specifically, the protrusion 204 is configured as a sheet structure, and the corresponding storage space 205 in the protrusion 204 is configured as a sheet structure adapted to the heating part 202, and the size of the storage space 205 is larger than the size of the heating part 202. This makes it easy to insert the heating part 202 into the storage space 205 of the protrusion 204. That is, the raised portion 204 is set as a sheet structure. When the raised portion 204 is connected to the flat portion 203, the distance between adjacent raised portions 204 can be reduced, so that when the heating component 20 is installed in the box 10 of the same volume, more raised portions 204 can be set, that is, the raised portion 204 is connected to the flat portion 203, and the raised portion 204 is arranged parallel to the flat portion 203. When the liquid in the flow channel 30 is heated, the efficiency of heating the liquid can be effectively improved.

[0032] In an optional embodiment, the protrusions 204 are staggered along a first direction, and the first direction is the length direction or the width direction of the box body 10. The protrusions 204 are staggered, and after the protrusions 204 of the housing 201 are inserted into the accommodating portion 101 of the box body 10, the flow channel 30 can be divided by the protrusions 204, so that the flow channel 30 surrounds the protrusions 204, thereby increasing the path for the liquid to flow in the flow channel 30. Specifically, the length direction or width direction of the box body 10 is the first direction, and the protrusion 204 can be arranged on the flat plate part 203 along the first direction. When the shell 201 is inserted into the accommodating part 101 of the box body 10, the protrusion 204 is arranged in the accommodating part 101 of the box body 10 in a staggered manner along the first direction, so that the flow channel 30 formed by the shell 201 and the box body 10 can be divided, and the flow channel 30 can be divided into an S-shaped flow channel 30, so that the liquid in the flow channel 30 surrounds the side wall of the protrusion 204, and when the liquid in the flow channel 30 is heated, the efficiency of heating the liquid can be effectively improved. In this embodiment, the length direction or width direction of the heating part 202 is the second direction, and the heating part 202 is inserted into the accommodating space 205 along the second direction. When installing the heating device, the heating part 202 can be inserted into the accommodating space 205 through the opening of the accommodating space 205 along the second direction, thereby completing the installation of the heating part 202.

[0033] In an optional embodiment, if Figure 3As shown, the portion of the heating part 202 disposed in the accommodation space 205 is spaced apart from the housing 201, and the heating assembly 20 further includes a heat-conducting insulating layer 40, which is disposed between the heating part 202 and the inner wall of the housing 201 forming the accommodation space 205. That is, the heat-conducting insulating layer 40 is formed between the heating part 202 and the inner side wall of the housing 201, that is, when the heating part 202 is inserted into the accommodation space 205 of the housing 201 along the second direction, the portion of the heating part 202 inserted in the accommodation is spaced apart from the inner side wall of the protrusion 204, and the heat-conducting insulating layer 40 is disposed between the gap between the heating part 202 and the inner side wall of the protrusion 204, and the heat-conducting insulating layer 40 can be used to quickly transfer heat to the protrusion 204 of the housing 201, thereby increasing the heat transfer efficiency. And if the heating part 202 is damaged, the heat-conducting insulating layer 40 can effectively prevent the heating part 202 from leaking electricity, thereby further increasing the safety of the heating device when in use. The heat-conductive insulating layer 40 may be a semi-cured material, so when the heat-conductive insulating layer 40 is disposed between the inner side wall of the accommodation space 205 of the protruding portion 204 and the protruding portion 204, the liquid semi-cured material may be poured into the accommodation space 205 of the protruding portion 204, and then the heating portion 202 may be inserted into the accommodation space 205 along the second direction. When the heating portion 202 is inserted into the accommodation space 205, the semi-cured heat-conductive insulating layer 40 is squeezed by the heating portion 202, so that the semi-cured insulating layer fills the gap between the inner side wall of the protruding portion 204 and the heating portion 202, and because the heat-conductive insulating layer 40 is in a flowing state, the heat-conductive insulating layer 40 can effectively fill the gap between the inner side wall of the protruding portion 204 and the heating portion 202, thereby effectively reducing the occurrence of leakage of the heating device. After the heat conductive insulating layer 40 fills the gap between the heating portion 202 and the inner wall of the protruding portion 204 , the semi-cured heat conductive insulating layer 40 can be cured by the heating portion 202 , so that the heat conductive insulating layer 40 protects the heating portion 202 .

[0034] In this embodiment, a plurality of brackets (not shown) are arranged on the side wall of the heating portion 202, and the brackets are supported on the inner side wall of the accommodation space 205 so that the axis of the heating portion 202 coincides with the axis of the accommodation space 205. That is, the brackets are arranged on the side wall of the heating portion 202, and when the heating portion 202 is inserted into the accommodation space 205 of the protrusion 204 along the second direction, the brackets are supported on the inner side wall of the accommodation space 205 so that the axis of the heating portion 202 coincides with the axis of the accommodation space 205. That is, the bracket is supported on the inner wall of the protrusion 204, so that the size between the side wall of the heating part 202 and the inner wall of the protrusion 204 is the same, so that the thickness of the heat-conducting insulating layer 40 between the inner wall of the protrusion 204 and the heating part 202 is the same, thereby avoiding the size of the heat-conducting insulating layer 40 being too large or too small, and effectively ensuring the effect of the heating part 202 transmitting to the inner wall of the protrusion 204 around. Avoid the situation where the heat conduction effect or insulation effect is poor on one side of the protrusion 204.

[0035] In other embodiments, Figure 2 As shown, a limit member 70 can be provided at one end of the heating portion 202 away from the protrusion 204, that is, when the heating portion 202 is inserted into the accommodating space 205 of the protrusion 204, the limit member 70 can be used to make the axis of the heating portion 202 coincide with the axis of the accommodating space 205, so that the gap size between the side wall of the heating portion 202 and the inner wall of the protrusion 204 is the same, so that the thermally conductive insulating layer 40 can be evenly filled in the gap between the protrusion 204 and the heating portion 202, and the limit member 70 can limit the length of the heating portion 202 inserted in the accommodating space 205, so that the end of the heating portion 202 away from the limit member 70, so that a gap is formed between the end of the heating portion 202 and the end of the protrusion 204, so that the thermally conductive insulating layer 40 wraps the heating portion 202, thereby improving the safety of the heating device.

[0036] In an optional embodiment, if Figure 4As shown, the housing 201 further includes a partition 50, which is located in the accommodating portion 101, and is arranged along a first direction. The partition 50 divides the accommodating portion 101 into a first channel 301 and a second channel 302. A through hole 501 is provided on the partition 50, and the through hole 501 connects the first channel 301 and the second channel 302. The partition 50 is arranged at one end of the housing 201 close to the box body 10, so that when the housing 201 is inserted into the accommodating portion 101 of the box body 10, the flow channel 30 can be divided into the first channel 301 and the second channel 302 by the partition 50. Specifically, the partition 50 is arranged on the flat plate portion 203 of the housing 201, and two rows of protrusions 204 are arranged side by side on the housing 201 along the first direction. The partition 50 is arranged on the flat plate portion 203 between the two rows of protrusions 204. When the housing 201 is inserted into the accommodating portion 101 of the box body 10, the end of the partition 50 away from the flat plate portion 203 abuts against the bottom wall of the box body 10, thereby dividing the flow channel 30 into the first channel 301 and the second channel 302. A through hole 501 is provided on the partition 50, and the through hole 501 connects the first channel 301 and the second channel 302. Specifically, the through hole 501 is arranged at the end of the partition 50 along the first direction, that is, the through hole 501 is located on one side of the inner wall of the box body 10. When the liquid flows in the flow channel 30, the first channel 301 can be transmitted to the second channel 302 through the through hole 501. Thus, the flow channel 30 surrounds the protrusion 204 , and the flow path of the liquid in the flow channel 30 is increased through the second channels 302 and the second channels 302 , thereby improving the heating efficiency of the liquid.

[0037] In an optional embodiment, if Figure 4 As shown, a water inlet pipe 601 and a water outlet pipe 602 are provided on the outside of the box body 10, and the water inlet pipe 601 and the water outlet pipe 602 are respectively connected to the first channel 301 and the second channel 302. The water inlet pipe 601 and the water outlet pipe 602 are provided on the outer wall of the box body 10 away from the end of the through hole 501 provided on the partition 50. Specifically, the water inlet pipe 601 can be connected to the first channel 301, and the water outlet pipe 602 is connected to the second channel 302. When it is necessary to heat the liquid, the liquid can be transferred to the first channel 301 through the water inlet pipe 601, and the liquid in the first channel 301 is transferred to the second channel 302 through the through hole 501, so that the liquid in the second channel 302 is transferred out through the water outlet pipe 602.

[0038] In a specific application scenario, when heating liquid, the heating part 202 is connected to an external power source, and the heating part 202 is powered by the external power source, so that the heating part 202 starts to heat, and the heat of the heating part 202 is transmitted to the side wall of the protrusion 204 through the heat-conducting insulation layer 40. Then the liquid is transmitted to the first channel 301 through the water inlet pipe 601, and the liquid entering the first channel 301 contacts the side wall of the protrusion 204, so that the side wall of the protrusion 204 provides heat for the liquid, and the liquid surrounds the side wall of the protrusion 204 in the first channel 301, and the liquid is heated by the protrusion 204. The liquid flows in the first channel 301 to the through hole 501, passes through the through hole 501 and is transmitted to the second channel 302, so that the protrusion 204 in the second channel 302 heats the liquid, and passes through the second channel 302 through the book outlet pipe. Since the liquid passes through the first channel 301 and the second channel 302 and is heated by the protrusions 204 disposed in the first channel 301 and the second channel 302 , the liquid is discharged through the water outlet pipe 602 after the heating is completed.

[0039] In an optional embodiment, the protrusion 204 is sequentially connected to the partition 50 and the side wall of the box body 10 along the first direction, so that the first channel 301 and the second channel 302 surround the outer side wall of the protrusion 204. The protrusion 204 is sequentially connected to the partition 50 and the side wall of the box body 10 along the first direction, so that when the liquid to be heated is passed into the flow channel 30, the liquid can be around the side wall of the protrusion 204, thereby improving the path of liquid flow. Specifically, one of the adjacent protrusions 204 is connected to the side wall of the partition 50, and the other is connected to the side wall of the box body 10, so that the first channel 301 and the second channel 302 are formed into an S shape, thereby increasing the contact area between the liquid and the protrusion 204. When the liquid enters the first channel 301 through the water inlet, the liquid surrounds the side wall of the protrusion 204, and the heat of the heating part 202 is transmitted to the liquid in the flow channel 30 through the side wall of the protrusion 204, thereby completing the heating of the liquid.

[0040] In an optional embodiment, when the liquid is transferred to the first channel 301 through the water inlet pipe 601, the liquid directly contacts one side end face of the protrusion 204. Since one end of the protrusion 204 contacts the side wall of the box body 10 or the side wall of the partition 50, the liquid can be transferred to the other side end face of the protrusion 204 and contact one side end face of the next-level protrusion 204. Therefore, when the liquid flows in the flow channel 30, the liquid can completely contact the side wall of the protrusion 204, thereby improving the heat transfer efficiency and thus improving the heating efficiency of the liquid.

[0041] In the above manner, the present application forms a receiving portion 101 in the housing 10, and inserts the heating component 20 into the housing 10. The heating component 20 includes a housing 201 and a heating portion 202. The housing 201 and the housing 10 are configured to form a flow channel 30. The housing 201 can separate the heating portion 202 from the liquid in the flow channel 30, simplifying the installation steps of the heating portion 202. The housing 201 prevents the heating portion 202 from contacting the liquid in the flow channel 30, and prevents the heating portion 202 from breaking and causing leakage of the heating device, thereby improving the safety of the heating device. The housing 201 is configured as a flat plate and a raised portion 204, and an accommodating space 205 is formed on the raised portion 204, and the heating portion 202 is inserted into the accommodating space 205. The raised portion 204 can be inserted into the housing 10, so that the contact area between the liquid and the raised portion 204 is reduced. By setting the heating part 202 and the protrusion 204 in a sheet-like manner, the layout capability of the heating device can be improved, and the contact area between the liquid and the protrusion 204 can be increased, thereby improving the heating efficiency of the liquid. By setting the protrusion 204 in a staggered manner along the first direction and connecting it to the side wall of the partition 50 and the side wall of the box body 10 in sequence, the path for the liquid to flow in the flow channel 30 is increased, thereby improving the efficiency of heating the liquid. By setting a heat-conducting insulating layer 40 in the accommodating space 205, and making the heat-conducting insulating layer 40 arranged on the side wall of the heating part 202 and the inner wall of the protrusion 204, it is possible to avoid leakage of the heating part 202 and improve the transmission efficiency of the liquid. By setting a plurality of brackets on the side wall of the heating part 202, the axis of the heating part 202 can be made to coincide with the axis of the accommodating space 205, so that the size of the heat-conducting insulating layer 40 is the same. By disposing a partition 50 on the housing 201 , the flow channel 30 can be divided into a first channel 301 and a second channel 302 , and by opening a through hole 501 on the partition 50 , the flow path of the liquid in the flow channel 30 can be effectively increased.
