[0027] The present invention will be further described below in detail with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0028] Example 1: Figures 1 to 6 As shown, a liquid heating structure described in this embodiment includes a heating base 1 made of a material with good thermal conductivity, the heating base 1 is a tubular structure, a heating layer 2 is provided on the surface of the heating base 1, and heat is generated by energizing the heating layer 2 to heat the heating base 1, and the heating base 1 is provided with a plurality of flow channel holes 11 along the trajectory of the heating layer 2, and at least one sealing member 3 is provided on the upper and lower sides of the heating base 1. The at least one sealing member 3 on both sides forms a flow channel with the plurality of flow channel holes 11, so that the liquid to be heated is heated in the flow channel to form a heated liquid or steam. Specifically, the diameter of the heating base 1 can be set according to the actual application scenario, the heating layer 2 is provided on the outer peripheral surface of the heating base 1, and the plurality of flow channel holes 11 are arranged at intervals along the circumferential direction.

[0029] In actual application, the liquid to be heated (such as water) is transported to the flow channel, and the heating layer 2 is energized to generate heat. The heat is directly conducted to the liquid to be heated in the flow channel through the heating base 1. As the liquid to be heated flows along the trajectory of the flow channel, the time for the liquid to be heated to flow through the heating base 1 is extended, so that the liquid to be heated can be fully heated in the flow channel, thereby achieving the heating of the liquid to be heated and forming heated liquid or steam. The heat is directly conducted from the heating base 1 to the liquid to be heated in the flow channel, and the heat conduction efficiency is higher.

[0030] In this embodiment, a plurality of flow channel holes 11 are provided in the heating base 1, and the sealing members 3 on both sides of the heating base 1 are used to form a flow channel through the plurality of flow channel holes 11, thereby directly forming a flow channel inside the heating base 1, improving the heat conduction efficiency, achieving a better heating effect, and having good pressure bearing capacity and sealing performance.

[0031] In the liquid heating structure described in this embodiment, the flow channel extends back and forth in an S-shape. This arrangement further prolongs the time for the heated liquid to flow through the heating base 1, allowing the heated liquid to be fully heated in the flow channel and achieving higher heat conduction efficiency.

[0032] like Figure 1 and Figure 2 As shown, in the liquid heating structure described in this embodiment, preferably, multiple sealing members 3 are provided on both sides of the heating base 1. In this embodiment, multiple flow channel holes 11 are provided in the heating base 1, and multiple sealing members 3 are provided on both sides of the heating base 1, so that the multiple flow channel holes 11 are formed into a continuous S-shaped reciprocating flow channel, thereby directly forming an S-shaped flow channel inside the heating base 1, improving heat conduction efficiency, achieving better heating effect, and having good pressure bearing capacity and sealing performance.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments of the liquid heating structure described in this embodiment, the heating base 1 is connected to a first interface 4 connected to one end of the flow channel and a second interface 5 connected to the other end of the flow channel. In this embodiment, the first interface 4 and the second interface 5 are provided to facilitate the delivery of the liquid to be heated into the flow channel and the discharge of the heated liquid or steam from the inner diameter of the flow channel.

[0034] In actual application, the first interface 4 can be set as an inlet and the second interface 5 can be set as an outlet according to actual design requirements; of course, the first interface 4 can also be set as an outlet and the second interface 5 can be set as an inlet.

[0035] like Figure 1 and Figure 2As shown, in this embodiment, the first interface 4 and the second interface 5 are located on the upper and lower sides of the heating base 1 to ensure that the heated liquid can be fully heated within the flow channel. In this embodiment, the first interface 4 is connected to one end of one of the outermost flow channel holes 11, and the second interface 5 is connected to one end of the other outermost flow channel hole 11.

[0036] In some embodiments of the liquid heating structure described in this embodiment, the first interface 4 and the second interface 5 are sealed and welded to the heating base 1. This arrangement makes the first interface 4 and the second interface 5 more firmly fixed and has better sealing performance.

[0037] In the liquid heating structure described in this embodiment, in some embodiments, the heating layer 2 is a thick film resistor layer. This embodiment uses a thick film heating resistor layer, which makes the overall structure smaller and more suitable for use in application scenarios with limited installation space.

[0038] Preferably, the thick film resistor layer is printed and sintered on the surface of the heating substrate 1. This arrangement allows the thick film resistor layer to be more firmly arranged on the surface of the heating substrate 1, thereby increasing reliability.

[0039] like Figures 2 to 5 As shown, in some embodiments of a liquid heating structure described in this embodiment, a plurality of communication grooves 12 are provided at intervals on both sides of the heating base 1 in the upper and lower directions. The communication grooves 12 can connect two adjacent flow channel holes 11, and the blocking member 3 is provided in each of the communication grooves 12. In this embodiment, the communication grooves 12 are provided to connect the corresponding two adjacent flow channel holes 11, and to facilitate the installation of the blocking member 3. Through the blocking member 3, the plurality of flow channel holes 11 are formed into a continuous reciprocating and extending flow channel. In this way, an S-shaped flow channel is directly formed in the heating base 1, thereby improving the heat conduction efficiency.

[0040] Preferably, the blocking member 3 is fixedly welded in the communicating groove 12. This arrangement enables the blocking member 3 to be more firmly mounted on the heating base 1 and to have better sealing performance.

[0041] like Figure 5 As shown, in some embodiments of the liquid heating structure described in this embodiment, the heating layer 2 is provided with at least two heating areas distributed along the flow direction of the liquid to be heated and having different power densities; the power densities of at least two heating areas decrease in sequence along the flow direction of the liquid to be heated. Specifically, at least two heating areas are distributed along the circumference of the heating substrate 1, so that different positions in the flow channel are heated with different powers to meet different heating requirements. For example, when saturated steam is required, saturated steam can be generated more fully. Figure 5As shown, the heating area can be set to two sections, three sections or more than three sections, and can be freely set according to actual design needs.

[0042] Specifically, when the first interface 4 is set as an inlet and the second interface 5 is set as an outlet, the power density of the heating area close to the first interface 4 is greater than the power density of the heating area close to the second interface 5 .

[0043] like Figure 6 As shown, a liquid heating structure of this embodiment also provides another structural mode, in which a blocking piece 3 is provided on both sides of the heating base 1; the blocking pieces 3 on both sides form a plurality of flow through holes 11 into a continuous S-shaped reciprocating flow channel. Such a configuration reduces the cost of using the structure, that is, a blocking piece 3 is provided on each side of the heating base 1, thereby forming a plurality of flow through holes 11 into a flow channel extending reciprocatingly in an S-shape; such a configuration has fewer structural parts, but the pressure bearing capacity is relatively inferior to the method of providing multiple blocking pieces 3. In this embodiment, specifically, strip grooves connected to each flow through hole are provided on both sides of the heating base 1; by providing the strip grooves, each flow through hole 11 is connected, and then the blocking piece 3 is used to form each flow through hole 11 into a flow channel extending reciprocatingly in an S-shape. Such a configuration facilitates the installation of the blocking piece 3 and makes the structure more secure.

[0044] Example 2: Figures 7 to 10 As shown, a liquid heating structure described in this embodiment includes a heating base 1 made of a material with good thermal conductivity, the heating base 1 is in a plate-like structure, and a heating layer (not shown in the figure) is provided on the surface of the heating base 1. The heating layer is energized to generate heat to heat the heating base 1. The heating base 1 is provided with a plurality of flow through holes 11 along the trajectory of the heating layer, and at least one sealing member 3 is provided on both sides of the left and right sides of the heating base 1. The at least one sealing member 3 on both sides forms a plurality of flow through holes 11 into a flow channel, so that the liquid to be heated is heated in the flow channel to form a heated liquid or steam. Specifically, the size of the heating base 1 can be set according to the actual application scenario, the heating layer is provided on a surface of the heating base 1 and extends along the length direction of the heating base 1; the plurality of flow through holes 11 are arranged at intervals along the length direction of the heating base 1.

[0045] In actual application, the liquid to be heated is transported to the flow channel, and the heating layer is energized to generate heat. The heat is directly conducted to the liquid to be heated in the flow channel through the heating base 1. As the liquid to be heated flows along the trajectory of the flow channel, the time for the liquid to be heated to flow through the heating base 1 is extended, so that the liquid to be heated can be fully heated in the flow channel, thereby achieving the heating of the liquid to be heated, and the heat is directly conducted from the heating base 1 to the liquid to be heated in the flow channel, and the heat conduction efficiency is higher.

[0046] In this embodiment, a plurality of flow channel holes 11 are provided in the heating base 1, and the sealing members 3 on both sides of the heating base 1 are used to form a flow channel through the plurality of flow channel holes 11, thereby directly forming a flow channel inside the heating base 1, improving the heat conduction efficiency, achieving a better heating effect, and having good pressure bearing capacity and sealing performance.

[0047] In the liquid heating structure described in this embodiment, the flow channel extends back and forth in an S-shape. This arrangement further prolongs the time for the heated liquid to flow through the heating base 1, allowing the heated liquid to be fully heated in the flow channel and achieving higher heat conduction efficiency.

[0048] In some embodiments of the liquid heating structure described in this embodiment, multiple sealing members 3 are provided on both sides of the heating base 1. This embodiment forms a continuous S-shaped reciprocating flow channel by providing multiple flow channel holes 11 within the heating base 1 and multiple sealing members 3 on both sides of the heating base 1. This improves heat conduction efficiency, achieves better heating effects, and improves pressure bearing capacity and sealing properties.

[0049] like Figure 7 、 Figure 8 and Figure 10 As shown, in some embodiments of the liquid heating structure described in this embodiment, the heating base 1 is connected to a first interface 4 connected to one end of the flow channel and a second interface 5 connected to the other end of the flow channel. In this embodiment, the first interface 4 and the second interface 5 are provided to facilitate the delivery of the liquid to be heated into the flow channel and the discharge of the heated liquid or steam from the inner diameter of the flow channel.

[0050] Preferably, the first interface 4 and the second interface 5 are distributed on the same diagonal position of the heating base 1, and the first interface 4 and the second interface 5 are vertically connected to the same surface of the heating base 1, so that the liquid to be heated has a longer flow path.

[0051] In actual application, the first interface 4 can be set as an inlet and the second interface 5 can be set as an outlet according to actual design requirements; of course, the first interface 4 can also be set as an outlet and the second interface 5 can be set as an inlet.

[0052] like Figures 7 to 9As shown, as an implementation of this embodiment, sealing members 3 are provided at both ends of the flow channel through hole 11 located on the outermost side, so that both ends of the flow channel formed in the heating substrate 1 are closed, and the first interface 4 is set as the inlet and the second interface 5 is set as the outlet for explanation. At this time, the first interface 4 is used to transport the liquid to be heated into the flow channel, the liquid to be heated flows along the flow channel, and the heated liquid or steam is discharged from the second interface 5.

[0053] In some embodiments of the liquid heating structure described in this embodiment, the first interface 4 and the second interface 5 are sealed and welded to the heating base 1. This arrangement makes the first interface 4 and the second interface 5 more firmly fixed and has better sealing performance.

[0054] In some embodiments of the liquid heating structure described in this embodiment, the heating layer is a thick film resistor layer. This embodiment uses a thick film heating resistor layer, which makes the overall structure smaller and more suitable for use in application scenarios with limited installation space.

[0055] Preferably, the thick film resistor layer is printed and sintered on the surface of the heating substrate 1. This arrangement allows the thick film resistor layer to be more firmly arranged on the surface of the heating substrate 1, thereby increasing reliability.

[0056] like Figure 9 As shown, in some embodiments of a liquid heating structure described in this embodiment, a connecting groove 12 is provided on both sides of the length direction of the heating base 1. The connecting groove 12 can connect the flow channel holes 11. The blocking member 3 is disposed in the connecting groove 12, so that the multiple flow channel holes 11 form a flow channel. In this embodiment, the connecting groove 12 is provided to connect the multiple flow channel holes 11, and it is convenient to install the blocking member 3. The multiple flow channel holes 11 form a flow channel through the blocking member 3, thus directly forming a flow channel in the heating base 1, thereby improving the heat conduction efficiency.

[0057] Preferably, combined Figures 7 to 9 As shown, the heating base 1 is provided with a plurality of connecting grooves 12 spaced apart on both sides of the longitudinal direction. The connecting grooves 12 are capable of connecting two adjacent flow channel holes 11. The blocking member 3 is provided in each of the connecting grooves 12, thereby forming the plurality of flow channel holes 11 into a continuous reciprocating and extending flow channel. In this embodiment, by providing a plurality of connecting grooves 12, the plurality of flow channel holes 11 are formed into a continuous reciprocating and extending flow channel through the plurality of blocking members 3. In this way, an S-shaped flow channel is directly formed within the heating base 1, further extending the flow path of the liquid to be heated, further improving the heat conduction efficiency, and achieving a better heating effect.

[0058] Preferably, the blocking member 3 is fixedly welded in the communicating groove 12. This arrangement enables the blocking member 3 to be more firmly mounted on the heating base 1 and to have better sealing performance.

[0059] In some embodiments of the liquid heating structure described in this embodiment, the heating layer is provided with at least two heating regions with different power densities distributed along the flow direction of the liquid to be heated; the power density of at least two heating regions decreases along the flow direction of the liquid to be heated. Specifically, at least two heating regions are distributed along the length of the heating substrate 1, thereby heating different locations within the flow channel with different powers to meet different heating requirements. For example, when saturated steam is required, saturated steam can be more fully generated. The heating regions can be provided in two, three, or more sections, and can be freely set according to actual design needs.

[0060] Specifically, when the first interface 4 is set as an inlet and the second interface 5 is set as an outlet, the power density of the heating area close to the first interface 4 is greater than the power density of the heating area close to the second interface 5 .

[0061] like Figure 10 As shown, a liquid heating structure of this embodiment also provides another structural mode, in which a blocking piece 3 is provided on both sides of the heating base 1; preferably, the blocking pieces 3 on both sides form the multiple flow through holes 11 into a continuous S-shaped reciprocating flow channel. Such a configuration reduces the cost of using the structure, that is, a blocking piece 3 is provided on each side of the heating base 1, thereby forming the multiple flow through holes 11 into a flow channel extending reciprocatingly in an S shape; such a configuration has fewer structural parts, but the pressure bearing capacity is relatively inferior to the method of providing multiple blocking pieces 3. In this embodiment, specifically, both sides of the heating base 1 are provided with strip grooves (not shown in the figure) connected to each flow through hole; by providing the strip grooves, each flow through hole 11 is connected, and then the blocking piece 3 is used to form each flow through hole 11 into a flow channel extending reciprocatingly in an S shape. Such a configuration makes it easier to install the blocking piece 3 and the structure is more secure.

[0062] like Figures 1 to 10 As shown, this embodiment also provides an instant heating device, including the liquid heating structure as described above. This embodiment adopts the above liquid heating structure, thereby having all the beneficial effects of the above liquid heating structure, which will not be repeated here.

[0063] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of protection of the present invention patent application.
