[0020] Figure 3 It is a top view of a heating tube for a small kitchen appliance provided by an embodiment of the utility model. Specific implementation method:

[0021] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] The following detailed description provides various embodiments or examples for implementing the present invention. Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0023] like Figures 1 to 3 As shown, this embodiment provides a heating tube for a small kitchen appliance, comprising a first heating tube 1, a second heating tube 2 and a flange 3. The flange 3 is used to be fixed on the small kitchen appliance. The first heating tube 1 and the second heating tube 2 extend into the small kitchen appliance. Both ends of the first heating tube 1 are connected to the flange 3, and both ends of the second heating tube 2 are connected to the flange 3. A heating element is provided in the first heating tube 1 and the second heating tube 2. When the heating element is powered on, the heating element is heated in the first heating tube 1 and the second heating tube 2, and the heat is transferred to the two tubes, thereby heating the liquid. One end of the heating element in the first heating tube 1 is connected to one end of the heating element in the second heating tube 2, and the other end is independent. In this way, the heating tube can be switched by switching the connection of the other end. If both are connected together, the two tubes can be heated. The length of the first heating tube 1 is longer than that of the second heating tube 2. The heating elements with different lengths have different lengths, thereby achieving different power conversion.

[0024] Preferably, the first heating tube 1 and the second heating tube 2 descend vertically from the flange 3, then bend and extend at the first bending position 11 until they extend to the second bending position 12 and then bend again. The first heating tube 1 and the second heating tube 2 extend horizontally after bending. When the first heating tube 1 extends to the end position of the second heating tube 2, the first heating tube 1 bends from the bottom position of the second heating tube 2 to the upper part of the second heating tube 2. The curved structure can make the whole more compact and reduce the occupied space, so that the first heating tube has sufficient length to improve the heating effect, and the power can be switched according to user needs.

[0025] Preferably, a temperature detection tube 4 extends from the bottom of the flange 3, and the temperature detection tube 4 is located between the first heating tube 1 and the second heating tube 2. A temperature probe is set in the temperature detection tube 4 to monitor the heat of the temperature detection tube 4 through the probe.

[0026] Preferably, the angle of the first bending position 11 is between 120-150°, and the angle of the second bending position 12 is between 40-60°. Within this angle range, the processing technology is simplest and the compactness is better.

[0027] Preferably, the end portion of the heating element is coated with insulating glue for fixation, and the insulating glue is used to fix the heating element and also to fix the terminal.

[0028] Preferably, the surfaces of the first heating tube 1 and the second heating tube 2 are plated with nobium. The nobium plating can increase the service life of the heating tube and reduce the speed of the heating tube.

[0029] Preferably, a first terminal 5 is fixed at the location where one end of the heating element in the first heating tube 1 is connected to one end of the heating element in the second heating tube 2. A second terminal 6 is fixed to the other end of the heating element in the first heating tube 1 and the other end of the heating element in the second heating tube 2, respectively. The first terminal 5 and the second terminal 6 can generate heat after being connected to external positive and negative electrodes. The first terminal 5 is connected to external power, and there are two second terminals 6, which can be switched or connected to achieve power conversion.

[0030] Preferably, the length L of the first heating tube 1 is 130-150 mm, and the length H of the first heating tube 1 is 190-200 mm. The first heating tube 1 in this size range is a preferred size, which is convenient for processing and installation.

[0031] The existing small kitchen treasure generally has only one heating tube installed, which has a slow heating effect. Installing two tubes will take up a lot of space or be insufficient in length due to the unreasonable structure, which makes the heating effect not improved. Therefore, a heating tube for a small kitchen treasure is provided, which extends into the small kitchen treasure through a first heating tube 1 and a second heating tube 2. The two ends of the first heating tube 1 are connected to a flange 3. A heating element is provided in the first heating tube 1 and the second heating tube 2. The length of the first heating tube 1 is longer than that of the second heating tube 2. The first heating tube 1 and the second heating tube 2 are vertically downward from the flange 3, and then bend and extend at a first bending position 11. The angle of the bending position 11 is between 120-150 degrees, until it extends to the position of the second bending position 12 and then bends. The angle of the second bending position 12 is between 40-60 degrees. The first heating tube 1 and the second heating tube 2 are bent and extended horizontally. When the first heating tube 1 extends to the end position of the second heating tube 2, the first heating tube 1 bends from the bottom position of the second heating tube 2 to the upper part of the second heating tube 2. The curved structure can make the whole more compact and reduce the space occupied, so that the first heating tube has sufficient length to improve the heating effect, and the power can be switched according to user needs.

[0032] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention are equivalent replacement methods and are included in the scope of protection of the present invention.
