[0034] The embodiment of the present application provides a heating base plate, as shown in the drawings, which comprises a base plate 2, a heating pipe 3 and a temperature controller 4. Figs. 1-3 The base plate 2 is upwardly convex to form a groove 21.

[0035] The base plate 2 is upwardly convex to form a groove 21.

[0036] The heating pipe 3 is arranged on the base plate 2 and abuts against the outer side wall of the groove 21, and the temperature controller 4 is arranged in the groove 21 and used for monitoring the temperature of the heating pipe 3.

[0037] According to the scheme, since the groove is formed at the bottom of the base plate 2 and the temperature controller 4 is installed in the groove 21, the temperature controller 4 is closer to the heating pipe 3, so that the monitoring of the temperature of the heating pipe 3 is more accurate. When the temperature of the heating pipe 3 is higher than the set value of the temperature controller 4, the temperature controller 4 automatically stops heating, stops the heating of the heating pipe 3, and effectively prevents the technical problem of dry burning caused by continuous heating of the heating pipe 3.

[0038] For example, the temperature controller 4 is set to 100℃, when the temperature of the heating tube 3 is higher than 100℃, the temperature controller 4 automatically cuts off the power, the heating tube 3 stops heating, which effectively prevents the technical problem of dry burning caused by the continuous heating of the heating tube 3. For another example, the temperature controller 4 is set to 120℃, when the temperature of the heating tube 3 is higher than 120℃, the temperature controller 4 automatically cuts off the power, the heating tube 3 stops heating, which prevents the technical problem of dry burning of the heating tube 3 caused by the distance between the temperature controller 4 and the heating tube 3 being too far. In this embodiment, the set value of the temperature controller 4 can be set to other values, and the specific value can be set according to the user's needs, which is not limited further herein.

[0039] In other embodiments, a control circuit is further included. When the temperature of the heating tube 3 is higher than the set value of the temperature controller 4, the temperature controller 4 sends the temperature value to the control circuit, the control circuit cuts off the circuit of the heating tube 3, the heating tube 3 stops heating, which prevents the technical problem of dry burning caused by the continuous heating of the heating tube 3. When the temperature of the heating tube 3 is lower than the set value of the temperature controller 4, the temperature controller 4 sends the temperature value to the control circuit, the control circuit connects the circuit of the heating tube 3, the heating tube 3 starts heating again, so that the temperature of the heating tube 3 heats to the preset value.

[0040] For example, the temperature controller 4 is set to 100℃, when the temperature of the heating tube 3 is higher than 100℃, the temperature controller 4 sends the temperature value to the control circuit, the control circuit cuts off the circuit of the heating tube 3, the heating tube 3 stops heating, which prevents the technical problem of dry burning caused by the continuous heating of the heating tube 3. For another example, the temperature controller 4 is set to 120℃, when the temperature of the heating tube 3 is higher than 120℃, the temperature controller 4 sends the temperature value to the control circuit, the control circuit cuts off the circuit of the heating tube 3, the heating tube 3 stops heating, which prevents the technical problem of dry burning of the heating tube 3 caused by the distance between the temperature controller 4 and the heating tube 3 being too far. In this embodiment, the set value of the temperature controller 4 can be set to other values, and the specific value can be set according to the user's needs, which is not limited further herein.

[0041] Further, as shown in Fig. 2 、 Fig. 3 the heating tube 3 is spirally wound into a spiral structure, one side of the spiral structure is a plane, and abuts against the outer side wall of the groove 21.

[0042] Specifically, the heating tube 3 spirally winds into a spiral plane with one end as the starting point, and the tube wall of the heating tube 3 abuts against the outer side wall of the groove 21.

[0043] It should be noted that, compared with the prior art, the heating tube 3 is not in direct contact with the bottom plate 2, that is, there is a gap between the heating tube 3 and the temperature controller 4, and it takes a certain time for the temperature of the heating tube 3 to be conducted to the temperature controller 4, and there is a risk of dry burning. In the embodiment, the heating tube 3 abuts against the bottom side wall of the groove 21, and the temperature controller 4 is arranged in the groove 21, so that the temperature controller 4 can directly monitor the temperature of the heating tube 3, making the temperature monitoring more accurate, and solving the technical problem of dry burning of the heating tube 3 caused by inaccurate temperature monitoring in the prior art.

[0044] In addition, the heating tube 3 is arranged in a spiral shape, which can significantly increase the contact area between the heating tube 3 and the heated object, so that the heat transfer is more uniform and efficient.

When the temperature of the heating tube 3 is higher than the set value of the temperature controller 4, the temperature controller 4 automatically cuts off the power supply, stops the heating of the heating tube 3, and effectively prevents the technical problem that the heating tube 3 is continuously heated to cause dry burning.

[0052] Specifically, the temperature controller 4 is a pair of parallel arrangements on the support 5 and is placed in the groove 21.
