[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] like Figures 1 to 5 As shown, the instant heating element of this utility model includes a heating tube body 1, the outer surface of which is coated with a heating coating; the heating tube body 1 is provided with an inlet 11 and an outlet 12, and an integrated flow guide is provided inside the heating tube body 1. The outer edge of the integrated flow guide is tightly fitted with the inner wall of the heating tube body 1, and the two ends of the integrated flow guide abut against the inlet 11 and the outlet 12 respectively. A spiral or wave-shaped water channel is formed between the integrated flow guide and the inner wall of the heating tube body 1, and the water channel connects the inlet 11 and the outlet 12. This design incorporates an integrated flow guide within the heating element body 1. The outer edge of the integrated flow guide is tightly fitted to the inner wall of the heating element body 1. Both ends of the integrated flow guide abut against the water inlet 11 and the water outlet 12, respectively. A spiral or wavy water path is formed between the integrated flow guide and the inner wall of the heating element body 1, which effectively guides the water flow, resulting in a longer water path and better heat exchange. Regardless of whether the heating element is installed horizontally or vertically, the water path can contact the inner wall of the heating element, preventing dry burning. The structure is simple and easy to assemble.

[0034] The outer surface of the heating element body 1 is coated with a heating coating, which has a simple structure and good heating effect.

[0035] Furthermore, the integrated flow guide includes a spiral blade 13, the axis of which is collinear with the axis of the heating element body 1; when water enters the heating element body 1, a spiral water path is formed. This design effectively guides the water flow, resulting in a longer water path and better heat exchange. Furthermore, regardless of whether the heating element is installed horizontally or vertically, the water path can contact the inner wall of the heating element, preventing dry burning. The structure is simple and easy to assemble.

[0036] Furthermore, the water inlet 11 is provided with a first anti-detachment groove 111 and a first sealing ring 112. With this configuration, when the water inlet 11 is connected to the water inlet pipe of an external device, the first anti-detachment groove 111 and the first sealing ring 112 can achieve the effects of preventing detachment and sealing against water leakage.

[0037] Furthermore, the water outlet 12 is provided with a second anti-detachment groove 121 and a second sealing ring 122. With this configuration, when the water outlet 12 is connected to an external equipment water outlet pipe, the second anti-detachment groove 121 and the second sealing ring 122 can achieve the effects of preventing detachment and sealing against water leakage.

[0038] Furthermore, the heating coating or thick film, wire winding, or plating, etc., enables rapid heating of the heating element body 1.

[0039] Furthermore, the heating tube body 1 is a hollow circular tube, with the water inlet 11 and the water outlet 12 respectively located at both ends of the heating tube body 1, and the water inlet 11, the water outlet 12 and the axis of the heating tube body 1 are on the same straight line.

[0040] Furthermore, it also includes a protective housing, which is installed on the outside of the heating element body 1. The protective housing has through holes at both ends to facilitate the extension of the water inlet 11 and the water outlet 12. This arrangement allows the protective housing to protect the heating element body 1.

[0041] Furthermore, the protective housing includes an upper shell 2 and a lower shell 3, which are fixedly connected. The upper shell 2 is equipped with a manual reset thermostat 21 and an automatic reset thermostat 22, while the lower shell 3 is equipped with multiple heat dissipation holes 31 arranged side by side. This configuration, through the manual reset thermostat 21 and the automatic reset thermostat 22, provides better temperature control; the heat dissipation holes 31 allow for rapid heat dissipation of the heating element body 1 when heating is stopped, thereby improving its service life.

[0042] Example 2:

[0043] like Figure 6 and Figure 7As shown, the integrated flow guide includes a screw 14, with a threaded plate 141 formed on the outer wall of the screw 14. The outer edge of the threaded plate 141 is tightly fitted to the inner wall of the heating tube body 1. The two ends of the screw 14 abut against the water inlet 11 and the water outlet 12, respectively. The axis of the screw 14 is on the same straight line as the axis of the heating tube body 1. The two ends of the screw 14 are respectively provided with a first flow guide groove 142. When water enters the heating tube body 1, a spiral water path can be formed. This design allows water to form a spiral water path when it enters the heating tube body 1, which can effectively guide the water flow, resulting in a longer water path and better heat exchange. Regardless of whether the heating element is installed horizontally or vertically, the water path can contact the inner wall of the heating element, preventing dry burning. Its structure is simple and easy to assemble. The materials of this integrated flow guide include injection-molded plastic parts, hardware, ceramics, quartz glass, etc.

[0044] The difference between this second embodiment and the first embodiment lies in the structure of the integrated flow guide. The rest of the structure and principle are the same as those in the first embodiment, and will not be repeated.

[0045] Example 3:

[0046] like Figures 8 to 10As shown, the integrated flow guide includes a mounting post 15. A first partition plate 151 and a second partition plate 152 are formed on the outer wall of the mounting post 15. The outer edges of the first partition plate 151 and the second partition plate 152 are tightly fitted to the inner wall of the heating tube body 1. The two ends of the mounting post 15 abut against the water inlet 11 and the water outlet 12, respectively. The axis of the mounting post 15 is on the same straight line as the axis of the heating tube body 1. The two ends of the mounting post 15 are respectively provided with second flow guide grooves 153. The first partition plate 151 and the second partition plate 152 are alternately arranged. The first partition plate 151 is provided with a first water passage groove 1511, and the second partition plate 152 is provided with a second water passage groove 1521. The oblique angle connecting the first water passage groove 1511 and the second water passage groove 1521 is the maximum distance of the oblique angle connecting the first partition plate 151 and the second partition plate 152. When water enters the heating tube body 1, a wave-shaped water path can be formed. This design creates a wave-like water path when water enters the heating element body 1, effectively guiding the water flow and extending the water path for better heat exchange. Regardless of whether the heating element is installed horizontally or vertically, the water path always contacts the inner wall of the heating element, preventing dry burning. The structure is simple and easy to assemble. The angled connection maximizes the straight-line distance, extending the water flow distance within the heating element body 1 and ensuring full contact with the inner wall, thus improving heat exchange efficiency. When direct heating of water to form steam is required, the water flow rate or volume can be controlled so that water enters through inlet 11 and steam exits through outlet 12, resulting in high heat exchange efficiency. The integrated flow guide is made of materials such as injection-molded plastic, hardware, ceramics, and quartz glass.

[0047] The difference between this embodiment three and embodiment one is that the structure of the integrated flow guide is different. The rest of the structure and principle are the same as those of embodiment one, and will not be repeated.

However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
