[0021] See also Figures 1 to 6 , the utility model preferably provides a technical solution: a single-tube heating element, comprising: a shell 1, a water pipe 2 and a heating pipe 3 arranged in the shell 1; the shell 1 is integrally formed by die-casting of aluminum parts; the water pipe 2 is a stacked ring structure as a whole, with both ends facing the upper and lower ends of the shell 1 and provided with a water inlet and a steam outlet; the heating pipe 3 includes a first terminal 301, a first end tube 302, an annular cavity tube 303, a second end tube 304, and a second terminal 305. The first terminal 301 is used as a starting point to connect the first end tube 302, the annular cavity tube 303, and the second end tube 304 in sequence and end at the second terminal 305. The annular cavity tube 303 is an elliptical ring and is placed between the first end tube 302 and the second end tube 304. At the same time, the first end tube 302, the annular cavity tube 303, and the second end tube 304 are built into the water pipe 2 and are used to heat the water pipe 2.

[0022] This application is mainly used for equipment such as steam cleaning machines;

[0023] Overall installation structure combination Figure 1 、 2 , 3, the disassembly and assembly structure is combined Figure 4 、 5 , 6, in order to solve the problem of poor heat conduction effect of the existing single-tube heating element, this application has made the following improvements;

[0024] First, the shell 1 is integrally formed by die-casting of aluminum. Aluminum has good thermal conductivity. After the shell 1 wraps the water pipe 2 and the heating pipe 3, the heat of the heating pipe 3 can be transferred to the water pipe 2 to a large extent, thereby improving the heating effect of the device.

[0025] Second; the water pipe 2 is a stacked ring structure, with both ends facing the upper and lower ends of the shell 1 and provided with a water inlet and a steam outlet. This design, combined with Figure 6 , through the stacked ring structure of the water pipe 2, firstly, the contact area with the water pipe 2 is increased, and secondly, the contact time with the water pipe 2 is increased, thereby improving the heat conduction effect;

[0026] Third; the heating tube 3 includes a first terminal 301, a first end tube 302, an annular cavity tube 303, a second end tube 304, and a second terminal 305. The first terminal 301 is used as a starting point to sequentially connect the first end tube 302, the annular cavity tube 303, the second end tube 304 and the second terminal 305. The annular cavity tube 303 is an elliptical ring and is placed between the first end tube 302 and the second end tube 304. At the same time, the first end tube 302, the annular cavity tube 303, and the second end tube 304 are built into the water pipe 2, combined with Figure 1 、 3 As shown in Figures 5 and 6, the special shape design of the heating tube 3 not only further improves the contact time and contact area between the heating tube 3 and the water pipe 2, but also the elliptical ring shape of the annular cavity tube 303 is mutually adapted to the stacked ring structure of the water pipe 2, and can be embedded in the installation, further saving the device space.

[0027] This design, through the material and structural characteristics of the shell 1, water pipe 2, and heating pipe 3, not only realizes the process of mutual embedding and wrapping of the three, reducing the spatial volume, but also expands the contact area between the water pipe 2 and the heating pipe 3 and prolongs the contact time between the water pipe 2 and the heating pipe 3. At the same time, the thermal conductivity of the shell 1 further ensures the thermal conductivity efficiency and thermal conductivity effect of the device.

[0028] Furthermore, a first flow channel and a second flow channel are opened inside the shell 1. The first flow channel and the second flow channel are distributed inside and outside and are used to limit the heating pipe 3 and the water pipe 2 respectively.

[0029] Combine Figure 2 As shown, the first flow channel and the second flow channel provided in the shell 1 not only limit the two, but also ensure the stability of the two. In addition, the shell 1 is cast from aluminum, which has good thermal conductivity, thereby ensuring the heat transfer from the heating tube 3 to the water pipe 2.

[0030] Furthermore, an inlet groove 6 and an outlet groove are respectively provided on the top and bottom of the shell 1 . The inlet groove 6 and the outlet groove are connected to the second flow channel and are arranged on the same longitudinal plane for the extension of the water inlet and the steam outlet of the water pipe 2 .

[0031] Combine Figure 1 、 4 As shown, since the water pipe 2 is an overall stacked ring structure, its two ends face the upper and lower sides of the shell 1 and are provided with a water inlet and a steam outlet. Here, the inlet groove 6 and the outlet groove are adapted to the morphological structure of the water pipe 2. At the same time, the water inlet and the steam outlet are placed on the same longitudinal plane, which not only facilitates the installation of the water pipe 2 and the cleaning machine, but also provides convenience for the integral molding and casting of the shell 1.

[0032] Furthermore, through holes 5 are respectively opened at opposite corners of the top of the housing 1 . The two through holes 5 are connected to the first flow channel and are used for extending the first terminal 301 and the second terminal 305 respectively.

[0033] Combine Figure 1 、 2 As shown in , 4 , the positions of the two through holes 5 here correspond to the morphological structure of the heating tube 3 .

[0034] Furthermore, the water inlet and the steam outlet of the water pipe 2 are respectively provided with mounting joints 4 , and the mounting joints 4 are in the shape of a cone with the tip facing outwards.

[0035] This design, combined with Figure 1 、 6 As shown, the installation joints 4 are respectively provided at the water inlet and the steam outlet of the water pipe 2. Their structural characteristics can improve the connection stability between the cleaning machine structure and the water pipe 2 through the installation joints 4 when the device is applied to the steam cleaning machine. The specific installation joints 4 are in the shape of a cone with the tip facing outward. Therefore, when the cleaning machine and the water pipe 2 are docked, the installation joints 4 can reduce the risk of the two falling off.

[0036] Furthermore, the upper portion of the housing 1 is provided with rounded corners, Figure 1 、 4 As shown, this design not only reflects the overall beauty of the device, but also reduces the size of the device. At the same time, the rounded corner design further improves the safety of the device.

[0037] In the present invention, unless otherwise clearly specified and limited, terms such as "install", "connect", "connect", and "fix" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, it can be through plug-in and snap-fitting, or through bolt connection, etc.

[0038] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
