[0027] The present application provides a heating device. Figure 1 As shown, the heating device of this embodiment includes: a shell 10 and a heating component 40. A flow channel 20 is formed in the shell 10, and a receiving portion 30 is also formed in the shell 10, and the receiving portion 30 is separated from the flow channel 20 by an inner wall 301. The heating component 40 is plugged into the receiving portion 30 and provides heat to the inner wall 301 to heat the liquid in the flow channel 20. Among them, the heating component 40 is used to connect to an external power supply, so that the heating component 40 is heated by the external power supply. After the heating component 40 is heated, it can heat the liquid in the flow channel 20. The heating component 40 in the receiving portion 30 is separated from the flow channel 20 of the shell 10 by the inner wall 301, thereby avoiding direct contact between the liquid in the flow channel 20 and the heating component 40, and improving the safety of the heating component 40 in heating the liquid in the heating flow channel 20. Among them, the heating component 40 is preferably a ceramic heater, and other heaters, such as electromagnetic heaters, infrared heaters, etc., can also be used, and this application does not make specific limitations here.

[0028] In an optional embodiment, in combination Figure 2 As shown, a housing portion 30 is formed in the shell 10, and a heating component 40 can be inserted into the housing portion 30. The heating component 40 is separated from the liquid in the flow channel 20 to prevent the heating component 40 from breaking, thereby preventing the heating component 40 from being electrically conductive with the liquid and causing a safety accident due to leakage of the heating component 40. The heating component 40 is separated from the flow channel 20 by the inner wall 301, so that the heat of the heating component 40 can heat the liquid in the flow channel 20 through the inner wall 301. Specifically, the shell 10 is provided with a accommodating portion 30, and the accommodating portion 30 of the shell 10 is formed by the inner wall 301, that is, the heating component 40 is separated from the flow by the inner wall 301 forming the accommodating portion 30, which effectively avoids direct contact between the day in the flow channel 20 and the heating component 40, thereby avoiding the occurrence of safety accidents such as leakage. When it is necessary to heat the liquid in the flow channel 20, the heating component 40 can be heated by an external power supply, thereby providing heat to the inner wall 301 forming the accommodating portion 30. After the inner wall 301 is heated, the liquid in the flow channel 20 is heated.

[0029] In an optional embodiment, the heating component 40 can be set to a rectangular shape, preferably the heating component 40 can be set to a cylindrical shape, which is not specifically limited in this application. Among them, the accommodating portion 30 can be formed in the middle of the shell 10, that is, the flow channel 20 of the shell 10 can be symmetrically arranged on the two side end faces of the accommodating portion 30, and the heating component 40 is set to a circular structure. The accommodating portion 30 forms a cylindrical structure relative to the heating component 40 through the inner wall 301. The heat utilization rate of the inner wall 301 of the accommodating portion 30 is high. The flow channel 20 of the shell 10 is symmetrically arranged around the inner wall 301 of the accommodating portion 30. The heating component 40 is connected to an external power supply, and the external power supply heats the heating component 40, so that the heating component 40 provides heat for the inner wall 301 of the accommodating portion 30. Since the flow channel 20 is arranged around the side wall of the accommodating portion 30, the heat of the inner wall 301 can be completely transferred to the liquid in the flow channel 20, thereby heating the liquid in the flow channel 20. In this embodiment, when installing the heating component 40, the heating component 40 can be directly plugged into the accommodating portion 30, which simplifies the step of assembling the heating component 40 in the accommodating portion 30. When the heating component 40 needs to be replaced, the heating component 40 can be directly taken out of the accommodating portion 30 without using other tools or disassembling the housing 10.

[0030] In the above embodiment, a receiving portion 30 and a flow channel 20 are formed in the shell 10, and the heating component 40 is inserted into the receiving portion 30. The receiving portion 30 and the flow channel 20 are separated by the inner wall 301, so that the heating component 40 is separated from the flow channel 20 formed by the shell 10. The heating component 40 is inserted into the receiving portion 30, which simplifies the assembly steps of the heating component 40, avoids direct contact between the heating component 40 and the liquid inside the flow channel 20, avoids the heating component 40 from breaking and causing leakage of the heating device, and effectively improves the safety of the heating device.

[0031] In an optional embodiment, the length direction of the heating component 40 is the first direction, and the heating component 40 is inserted into the accommodating portion 30 along the first direction. There are a plurality of accommodating portions 30, and the arrangement direction of the accommodating portion 30 components is the second direction, the second direction is arranged crosswise with the first direction, and the flow channel 20 is arranged along the second direction. Among them, the first direction and the second direction can be arranged perpendicularly, that is, the arrangement direction of the accommodating portion 30 can be perpendicular to the first direction. The heating component 40 is inserted into the accommodating portion 30, that is, when the heating component 40 is inserted into the accommodating portion 30, the heating component 40 is inserted into the accommodating portion 30 along the length direction of the heating component 40, and the heating component 40 is inserted into the accommodating portion 30 along the axial direction of the length of the accommodating portion 30. A plurality of accommodating portions 30 are provided, and a heating component 40 is arranged in the accommodating portion 30. The liquid inside the flow channel 20 can be heated by multiple heating components 40. By providing multiple accommodating portions 30 and arranging heating components 40 in the accommodating portions 30, the efficiency of heating the liquid in the flow channel 20 can be effectively improved.

[0032] In an optional embodiment, if Figure 3As shown, the heating device includes a third direction, which is arranged crosswise with the first direction and the second direction, and a plurality of vertical plates 501 are arranged along the third direction on both side end surfaces of the inner wall 301 to form a flow channel 20. The third direction is perpendicular to the plane formed by the first direction and the second direction, that is, the third direction is perpendicular to the first direction and the second direction respectively, and the third direction is perpendicular to the first direction and the second direction in pairs. The flow channel 20 is symmetrically arranged on opposite sides of the inner wall 301 forming the accommodating portion 30, and vertical plates 501 are formed. There are a plurality of vertical plates 501, so that the flow channel 20 is formed by the vertical plates 501. The vertical plates 501 are arranged on the inner wall 301 along a first direction, and the length of the vertical plates 501 along the first direction is less than the length of the heating component 40 along the first direction, so that the flow channel 20 along the shell 10 is formed into a U-shaped structure along the first direction through the vertical plates 501, and the flow channel 20 is divided by the vertical plates 501 along the second direction, that is, the liquid in the flow channel 20 can be heated by the heating bodies arranged in the plurality of accommodating portions 30, thereby improving the heating speed of the liquid in the heating flow channel 20. That is, the vertical plate 501 is arranged along the length direction of the accommodating portion 30, and is arranged once along the arrangement direction of the accommodating portion 30, and the vertical plate 501 is staggered along the second direction, so that the vertical plate 501 divides the flow channel 20 into inner walls 301 surrounding the end surfaces of both sides of the accommodating portion 30, so that the heating component 40 can quickly heat the liquid inside the flow channel 20.

[0033] In an optional embodiment, a water inlet 601 and a water outlet 602 are provided on one side of the housing 10 along the first direction, and the water inlet 601 and the water outlet 602 are connected to the flow channel 20. Specifically, the water inlet 601 and the water outlet 602 are provided along the first direction in the direction of the housing 10 away from the heating component 40 inserted on one side of the accommodating portion 30, and the flow channel 20 is formed on opposite sides of the inner wall 301 forming the accommodating portion 30 along the third direction, that is, the inner wall 301 is provided with the flow channel 20 in both the positive direction and the reverse direction along the third direction, the water inlet 601 can be connected to the flow channel 20 in the positive direction of the third direction, and the water outlet 602 can be connected to the flow channel 20 in the reverse direction of the third direction. Among them, a through hole 302 is opened on the inner wall 301, and the through hole 302 connects the flow channels 20 at both ends of the inner wall 301, that is, the liquid to be heated enters the flow channel 20 in the positive direction of the third direction, and the liquid can flow in the flow channel 20 along the second direction. The liquid can flow into the flow channel 20 in the opposite direction of the third direction through the through hole 302 set on the inner wall 301, and then the liquid after heating is discharged through the water outlet 602.

[0034] In this embodiment, if Figure 4As shown, the inner wall 301 is provided with a through hole 302 along the third direction, the through hole 302 is arranged at the end of the inner wall 301 along the second direction, and is arranged at the end of the inner wall 301 along the first direction, and the water inlet 601 and the water outlet 602 are arranged in parallel along the third direction in the direction of the housing 10 away from the heating component 40 inserted in the accommodating portion 30. For example, the water inlet 601 is arranged on one side along the positive direction of the third direction, and the water outlet 602 is arranged on one side in the opposite direction of the third direction. The liquid to be heated enters the flow channel 20 in the positive direction of the third direction of the housing 10 through the water inlet 601. Since the vertical plate 501 divides the flow channel 20 into a U-shaped structure along the first direction and is staggered along the second direction, the liquid to be heated flows around the flow channel 20 along the second direction to the position of the through hole 302 of the inner wall 301, and enters the inside of the flow channel 20 in the opposite direction of the third direction through the through hole 302. Since the heating assembly 40 is inserted into the accommodating parts 30 arranged side by side along the second direction, the liquid in the flow channel 20 surrounding the accommodating parts 30 can be heated, and discharged through the water blowing port after heating.

[0035] In an optional embodiment, the vertical plate 501 is arranged between the accommodating parts 30 and on the side wall at the axial position of the accommodating parts 30, that is, a plurality of accommodating parts 30 are arranged side by side, and the vertical plate 501 is arranged between the accommodating parts 30, and the vertical plate 501 is arranged on the side wall at the axial position of the accommodating parts 30, that is, it is arranged in the axial direction of the accommodating parts 30 and extends along the first direction and the third direction. That is, the vertical plate 501 divides the side wall of the accommodating part 30 and the liquid contact position into two parts, so that the heating component 40 heats the liquid in the flow channel 20 to form the inner wall 301 of the accommodating part 30, reducing the heat loss when the heating component 40 heats the liquid in the flow channel 20.

[0036] In an optional embodiment, if Figure 4 As shown, a partition 502 is provided on one end face of the shell 10 along the third direction, and the partition 502 is used to divide the flow channel 20 into a first channel 201 and a second channel 202. The first channel 201 and the second channel 202 are respectively connected to the water inlet 601 and the water outlet 602. Specifically, a partition 502 is provided on the inner wall 301 along the third direction, and the partition 502 extends along the third direction and the first direction, thereby dividing the flow channel 20 on one side of the inner wall 301 into the first channel 201 and the second channel 202. The partition 502 can symmetrically divide the inner wall 301 into the first channel 201 and the second channel 202 along the second direction, and can also be set so that the capacity of the first channel 201 is less than or greater than the capacity of the second channel 202. The specific setting can be based on actual needs, and this application does not make specific limitations here.

[0037] In this embodiment, the partition 502 can divide the flow channel 20 into a first channel 201 and a second channel 202 in the positive direction of the third direction, and the first channel 201 and the second channel 202 are connected to the water inlet 601 and the water outlet 602 respectively. At this time, two through holes 302 opened on the inner wall 301 along the third direction can be set, and the two through holes 302 are both set at the ends of the inner wall 301 of the flow channel 20 along the first direction and the second direction. Among them, the partition 502 is not set on the inner wall 301 in the opposite direction of the third direction, that is, the flow channel 20 in the positive direction of the third direction is divided into two channels, and the flow channel 20 in the opposite direction of the third direction is a whole. When heating the liquid, the liquid can enter the first flow channel 20 through the water inlet 601, enter the flow channel 20 in the opposite direction of the third direction through the through hole 302, enter the second channel 202 through the through hole 302, and then be discharged through the water outlet 602.

Among them, the side wall of the heating component 40 is evenly surrounded by a limiter, and the limiter abuts against the inner wall 301 forming the accommodating portion 30, so that the axis of the heating component 40 coincides with the axis of the accommodating portion 30, so that the gap size between the heating component 40 and the inner wall 301 is the same, so that the thickness of the first insulating layer formed in the gap is evenly set, avoiding that the thickness of part of the heating component 40 is too small, resulting in poor insulation effect, and at the same time avoiding that the thickness of part of the heating component 40 is too large, resulting in poor heating effect. When installing the heating component 40 in the accommodating portion 30, the liquid first insulating layer can be first injected into the accommodating portion 30, and then the heating component 40 is inserted into the accommodating portion 30 along the first direction, and the heating component 40 squeezes the first insulating layer arranged in the accommodating portion 30, so that the first insulating layer fills the gap formed between the heating component 40 and the inner wall 301 under the squeezing of the heating component 40, so that the first insulating layer is evenly laid in the gap.

After the heating assembly 40 is installed, the liquid can be introduced into the first channel 201 in the positive direction of the third direction through the water inlet 601, and enter the flow channel 20 in the opposite direction of the third direction through the through hole 302. After the liquid passes through the flow channel 20 in the opposite direction of the third direction, it enters the second channel 202 in the positive direction of the third direction through another through hole 302, and the liquid in the second channel 202 is discharged through the water outlet 602.

By setting a plurality of receiving portions 30 and arranging them along the second direction, the heating component 40 can heat the liquid inside the flow channel 20 through the inner wall 301 of the receiving portion 30, effectively improving the efficiency of heating the liquid in the flow channel 20. By setting a plurality of vertical plates 501 on the end faces of both sides of the inner wall 301 along the third direction, the flow channel 20 can be divided into a plurality of U-shaped structures, thereby improving the heating speed of the liquid in the heating flow channel 20. By displacing the vertical plate 501, the vertical plate 501 can divide the flow channel 20 into two parts. The vertical plate 501 is wound around the inner wall 301 on both sides of the end surface of the accommodating portion 30, and the liquid inside the heating flow channel 20 is added. By setting the water inlet 601 and the water outlet 602 on one side of the shell 10 along the first direction, the liquid can be transferred to the flow channel 20 through the water inlet 601 and discharged through the water outlet 602. By opening the through hole 302 on the inner wall 301, the liquid in the flow channel 20 on one side of the inner wall 301 in the third direction can be transferred to the flow channel 20 on the other side of the inner wall 301. By setting the vertical plate 501 between the accommodating portions 30 and on the side wall at the axial position of the accommodating portion 30, the heat loss of the heating component 40 heating the liquid in the flow channel 20 can be reduced. By setting the partition 502 on the inner wall 301 along the third direction, the flow channel 20 can be divided into the first channel 201 and the second channel 202, so that the inside of the liquid flow channel 20 is surrounded by heating. By forming a first insulating layer between the heating component 40 and the inner wall 301 forming the accommodating portion 30, the heating component 40 can be prevented from breaking and causing leakage, thereby improving the safety of the heating device. By providing a cover plate 70 at one end of the heating component 40 and detachably connecting it to the housing 10, the heating component 40 can be easily replaced. By providing a heating body, a first annular tube, and a second annular tube in the heating component 40, it is further possible to prevent the liquid from directly connecting with the heating body of the heating component 40. By providing a second insulating layer between the first annular tube, the second annular tube, and the heating body, the safety of the heating device can be further improved.
