DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail below in combination with the drawings and specific embodiments, and is not limited to the scope of the utility model by this.

[0023] As Figures 1 to 3 shown, the liquid electric heating module comprises a heating tube 1, and a liquid inlet connector 2 and a liquid outlet connector 3 connected to both ends of the heating tube 1.

[0024] Preferably, as Figure 1 and Figure 2 shown, the heating tube 1 is a thick-film heating tube 1, which comprises a tube body 11 and a thick-film heating layer 12 arranged on the outer peripheral wall of the tube body 11; so that the overall structure is smaller in size, more beautiful, and better in heating effect.

[0025] Specifically, as Figure 1 shown, the heating tube 1, the liquid inlet connector 2 and the liquid outlet connector 3 jointly enclose a first heating cavity; by arranging the first heating cavity, the partition 4 and the plug 5 are installed.

[0026] The first heating cavity is provided with a partition 4 coaxially arranged with the heating tube 1; both ends of the partition 4 are provided with plugs 5 abutting with the liquid inlet connector 2 and the liquid outlet connector 3 respectively;

[0027] As Figure 1 shown, the heating tube 1, the liquid inlet connector 2, the liquid outlet connector 3, the partition 4 and the plug 5 jointly enclose a second heating cavity 6 in the form of a ring; by forming the second heating cavity 6 in the form of a ring, the thickness of the liquid to be heated is reduced, so that the liquid to be heated is heated more quickly and the heating efficiency is higher; the outer end surface of each of the two plugs 5 is concavely provided with a notch 53; the two notches 53 communicate the second heating cavity 6 with the liquid inlet connector 2 and the liquid outlet connector 3.

[0028] In actual use, the liquid electric heating module of the embodiment is provided with the partition 4 in the heating tube 1, and the plugs 5 with notches 53 are arranged at both ends of the partition 4; when the liquid to be heated enters the second heating cavity 6 from the liquid inlet connector 2 through the notches 53 of the plugs 5, it enters along the wall of the heating tube 1 and does not directly spray into the second heating cavity 6; when the heated liquid flows out from the second heating cavity 6 to the liquid outlet connector 3 through the notches 53 of the plugs 5, it can flow out along the wall of the heating tube 1 and does not directly spray out to the liquid outlet connector 3; in this way, the liquid in the second heating cavity 6 is more sufficient, dry burning is less likely to occur, the liquid outlet is more smooth and does not stop and start intermittently, and the temperature fluctuation is small. At the same time, since the liquid outlet does not spray one by one, the noise of the structure in use is smaller.

[0029] As Figure 1As shown in this embodiment, in some implementations of the liquid electric heating module, the partition 4 is preferably a hollow tube; both ends of the hollow tube are respectively sealed to the plugs 5. This embodiment uses a hollow tube with a hollow structure, resulting in a lighter overall structure and lower manufacturing cost; it also facilitates the full transfer of heat generated by the heating element 1 into the liquid. Of course, the partition 4 can also be a solid tube structure, but the overall structure will be relatively heavier.

[0030] like Figure 1 As shown in this embodiment, in some implementations of a liquid electric heating module, a spiral component 7 extending spirally around the axis of the heating tube 1 is provided in the second heating chamber 6. This embodiment guides the liquid flowing through the second heating chamber 6 by providing the spiral component 7, resulting in a spiral flow and a mixed flow effect. This leads to a more uniform liquid heating temperature, a smaller temperature difference, and more accurate temperature detection of the liquid outlet. Simultaneously, it reduces the noise caused by the bursting of bubbles during heating, further reducing heating noise.

[0031] like Figure 1 As shown in this embodiment, in some implementations of the liquid electric heating module, the spiral component 7 is preferably a spring, which makes assembly more convenient. Alternatively, a spiral groove structure can be provided on the outer peripheral wall of the spacer 4.

[0032] like Figure 1 As shown in this embodiment, in some implementations of a liquid electric heating module, the inner wall of the spring abuts against the outer wall of the partition tube; the outer wall of the spring abuts against the inner wall of the heating tube 1; with this arrangement, the heating tube 1, the hollow tube and the spring cooperate to form a spiral surrounding liquid channel, further reducing the effective space of the second heating chamber 6, resulting in more thorough and uniform heating and a smaller temperature difference.

[0033] like Figure 1 As shown in this embodiment, in some implementations of a liquid electric heating module, the two ends of the spring abut against the corresponding plugs 5. This arrangement ensures that the spring is reliably installed in the second heating chamber 6, and also facilitates the inflow and outflow of liquid from the second heating chamber 6.

[0034] like Figure 1 and Figure 1As shown in this embodiment, in some implementations of a liquid electric heating module, the notch 53 is U-shaped. The notch 53 is recessed inward from the outer end of the plug 5 and extends through the sidewall of the plug 5 in both directions. This design allows the liquid to be heated flowing in from the inlet connector 2 to flow smoothly along the pipe wall of the heating tube 1 into the second heating chamber 6 through the U-shaped notch 53, and the heated liquid in the second heating chamber 6 to flow smoothly along the pipe wall of the heating tube 1 through the U-shaped notch 53 to the outlet connector 3. This makes the liquid flow smoother and more stable, thereby achieving the effect of lower heating noise.

[0035] like Figure 3 and Figure 1 As shown in this embodiment, in some implementations of a liquid electric heating module, the plug 5 includes an integrally formed body 51 and a tapered portion 52; the tapered portion 52 is connected to the surface of the body 51 facing the partition 4; the notch 53 is provided on the surface of the body 51 facing away from the partition 4. This embodiment, by providing the tapered portion 52, makes it easier for the plug 5 to be assembled onto the partition tube; and by providing an integrally formed structure, the plug 5 has better durability.

[0036] like Figure 3 As shown in this embodiment, in some implementations of a liquid electric heating module, the two ends of the heating element 1 are respectively sealed to the liquid inlet connector 2 and the liquid outlet connector 3 via sealing elements 8; this arrangement ensures the sealing performance between the heating element 1 and the liquid inlet connector 2 and the liquid outlet connector 3. Preferably, the sealing element 8 is a sealing sleeve, which provides better sealing performance.

[0037] like Figure 1 and Figure 1 Figure 3 As shown, in some embodiments of the liquid electric heating module described in this embodiment, the plug 5 has connecting arms 54 extending from both sides of the notch 53; the connecting arms 54 of the plug 5 that abut against the liquid inlet connector 2 extend into the liquid inlet connector 2; the connecting arms 54 of the plug 5 that abut against the liquid outlet connector 3 extend into the liquid outlet connector 3; in this embodiment, by setting the connecting arms 54, the plug 5 and the liquid inlet connector 2 are more tightly assembled, the plug 5 and the liquid outlet connector 3 are more tightly assembled, and it is also convenient for the liquid to flow from the center of the notch 53 to both sides into the second heating chamber 6, and for the liquid to flow from both sides of the notch 53 to its center into the liquid outlet connector 3. In this way, the liquid can reliably flow along the pipe wall of the heating tube 1 when flowing into and out of the second heating chamber 6.

[0038] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
