[0012] Compared with the prior art, the present invention provides an instant heating tube with the following beneficial effects:

[0013] Compared with existing instant heating tubes on the market, this instant heating tube has a longer damping spring that covers most of the outside of the heating tube body. The damping spring can effectively reduce the water flow velocity so that the water flow can fully contact the heating tube body. At the same time, the heating tube body can heat the water flow through the damping spring, further ensuring the heating efficiency of the water flow. The heating tube assembly adopts a top water inlet and side outlet design, which is suitable for different installation environments. The distance between the inner wall of the outer tube and the outer wall of the heating tube body is reasonably controlled so that the water flow can fully contact the heating tube body.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-3The utility model discloses an instant heating pipe, including a heating pipe assembly 1, wherein the heating pipe assembly 1 includes an outer pipe 11, a heating pipe body 12 is arranged inside the outer pipe 11, and one end of the heating pipe body 12 extends to one side of the outer pipe 11, which is convenient for the subsequent connection of wires. A heating pipe water inlet pipe 14 is arranged at the top of the outer pipe 11, and a heating pipe water outlet pipe 16 is arranged at the bottom of the outer pipe 11.

[0024] Specifically, the interior of the outer tube 11 is provided with a damping spring 13 which is sleeved with the outside of the heating tube body 12. The damping spring 13 is relatively long and covers most of the outside of the heating tube body 12. The damping spring 13 can effectively reduce the water flow velocity so that the water flow can fully contact the heating tube body 12, thereby ensuring the heating effect of the water flow. At the same time, the heating tube body 12 can heat the water flow through the damping spring 13, further ensuring the heating efficiency of the water flow.

[0025] Specifically, a heating tube top cover 17 is provided at the top of the outer tube 11, the heating tube water inlet pipe 14 is provided at the top of the heating tube top cover 17, a heating tube water outlet 15 is provided at the bottom of the outer tube 11, the heating tube water outlet pipe 16 is provided at the bottom of the heating tube water outlet head 15, and the heating tube water inlet pipe 14 is provided at the top of the heating tube top cover 17. The heating tube assembly 1 adopts a top water inlet and side outlet design, which is suitable for different installation environments.

[0026] Specifically, the outer diameter of the outer tube 11 is 11mm-22mm, the outer diameter of the heating tube body 12 is 9mm-14mm, and the distance between the inner wall of the outer tube 11 and the outer wall of the heating tube body 12 is 1mm-4mm. The distance between the inner wall of the outer tube 11 and the outer wall of the heating tube body 12 is reasonably controlled so that the water flow can fully contact the heating tube body 12, avoiding the situation where the distance between the inner wall of the outer tube 11 and the outer wall of the heating tube body 12 is too large, resulting in the water flow close to the inner wall of the outer tube 11 not being fully heated, thereby ensuring the heating effect.

[0027] Example 2:

[0028] See also Figure 1-6 Compared with the above embodiment, in this embodiment, the water inlet pipe 14 of the heating tube is arranged on one side of the outer tube 11, and the top of the heating tube body 12 is in contact with the bottom of the heating tube top cover 17. Later, a hole is punched inside the heating tube top cover 17 to pass the wires connecting the heating tube body 12. In this embodiment, the heating tube assembly 1 adopts the side water inlet and top wire outlet method, which can be adapted to different installation environments.

[0029] To sum up, compared with the existing instant heating tubes on the market, the damping spring 13 of this instant heating tube is longer and covers most of the outside of the heating tube body 12. The damping spring 13 can effectively reduce the water flow speed so that the water flow can fully contact the heating tube body 12. At the same time, the heating tube body 12 can heat the water flow through the damping spring 13, further ensuring the heating efficiency of the water flow. The heating tube assembly 1 adopts the design of top water inlet and side outlet, which is suitable for different installation environments. It reasonably controls the distance between the inner wall of the outer tube 11 and the outer wall of the heating tube body 12, so that the water flow can fully contact the heating tube body 12.
