DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0027] like Figures 1 to 7 As shown, a plate-shaped steam heating structure described in this embodiment includes a heating plate 1, wherein the heating plate 1 has a heating cavity, and the upper and lower ends of the heating plate 1 are respectively provided with a first joint 2 and a second joint 3 connected to the heating cavity, and a first mounting plate 4 is fixedly provided on one side of the heating plate 1;

[0028] A temperature detector 5 is provided on the side of the first mounting plate 4 facing the heating plate 1 near the first joint 2, and an elastic member 6 is connected between the temperature detector 5 and the first mounting plate 4, and the elastic member 6 is configured to keep the temperature detector 5 in a state of pressing contact with the surface of the heating plate 1.

[0029] Specifically, when the plate-shaped steam heating structure of this embodiment is actually used, the liquid to be heated (such as water) is transported into the heating chamber through the first joint 2, the heating plate 1 heats the liquid to be heated in the heating chamber to generate steam, and the steam is discharged from the heating chamber through the second joint 3, thereby realizing steam transportation, and the temperature detector 5 detects the steam temperature in the heating chamber under the elastic force of the elastic member 6 to control the temperature of the steam.

[0030] In this embodiment, a first mounting plate 4 is provided to facilitate the installation of the temperature detector 5. The temperature detector 5 is arranged to pass through the first mounting plate 4, and the elastic member 6 is used to keep the temperature detector 5 in pressure contact with the surface of the heating plate 1, thereby effectively preventing the temperature detector 5 from falling off due to high temperature, ensuring more accurate temperature detection and higher reliability of the structure.

This embodiment adopts the NTC temperature sensor, which has the characteristics of high sensitivity, fast response speed and simple and flexible structure.

[0032] like Figures 1 to 3 As shown, in the plate-shaped steam heating structure described in this embodiment, in some embodiments, the temperature detector 5 is connected with a lead plug 51. In this embodiment, the lead plug 51 is provided to facilitate the wiring operation of the temperature detector 5 and the assembly is more convenient.

[0033] like Figures 1 to 4 As shown, in the plate-shaped steam heating structure described in this embodiment, in some embodiments, the first mounting plate 4 is provided with a first mounting portion 41, and the temperature detector 5 is movable through the first mounting portion 41. In this embodiment, by providing the first mounting portion 41, a guide and a limit are provided for the installation of the temperature detector 5, so that the installation of the temperature detector 5 is more stable and reliable, and the accuracy of temperature detection is further guaranteed.

[0034] like Figures 1 to 3 As shown, in the plate-shaped steam heating structure described in this embodiment, in some embodiments, the elastic member 6 is a spring. Specifically, the spring is sleeved on the outer wall of the temperature detector 5 and the outer wall of the first mounting portion 41, so that the elastic force applied by the spring to the temperature detector 5 is perpendicular to the surface of the heating plate 1, so that the surface of the temperature detector 5 is in contact with the surface of the heating plate 1 more stably.

[0035] It should be noted that the elastic member 6 may also adopt other elastic structures, such as a spring sheet structure.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the plate-shaped steam heating structure described in this embodiment, the first mounting plate 4 is provided with first strip holes 42 spaced apart along its length direction. In this embodiment, the first strip holes are provided on the first mounting plate 4 to dissipate the heat from the periphery of the heating plate 1, thereby preventing the heat from being concentrated between the first mounting plate 4 and the heating plate 1 and affecting the detection accuracy of the temperature detector 5.

When disassembly and assembly are required, the first clamping spring 461 is squeezed through the first clamping hole 45, and then the first spring terminal 46 is pulled out from the first mounting hole 44, and the structural assembly is more convenient.

[0039] Specifically, Figure 6 As shown, the first spring terminal 46 has a Z-shaped structure, so that the elastic stress of the first spring terminal 46 can be used to crimp the other end of the first spring terminal 46 onto the surface of the heating plate 1, thereby enhancing the electrical connectivity between the first spring terminal 46 and the heating plate 1.

[0040] Exemplarily, the other end of the first spring terminal 46 is welded and fixed to the heating plate 1 , so that the electrical connection performance between the first spring terminal 46 and the heating plate 1 is stronger.

Therefore, during assembly, one end of the second spring terminal 74 is inserted into the second plug hole 72, and the second clamping spring 741 is squeezed until the position of the second clamping spring 741 corresponds to the position of the second clamping hole 73, and the second clamping spring 741 is automatically clamped into the second clamping hole 73, so that the second spring terminal 74 is fixed on the third mounting portion 71. When disassembly and assembly are required, the second clamping spring 741 is squeezed through the second clamping hole 73, and then the second spring terminal 74 is pulled out from the second plug hole 72, and the structural assembly is more convenient.

[0047] Specifically, Figure 7 As shown, the second spring terminal 74 is in a Z-shaped structure, so that the elastic stress of the second spring terminal 74 can be used to crimp the other end of the second spring terminal 74 onto the surface of the heating plate 1, thereby enhancing the electrical connectivity between the second spring terminal 74 and the heating plate 1.

[0048] Exemplarily, the other end of the second spring terminal 74 is welded and fixed to the heating plate 1 , so that the electrical connection performance between the second spring terminal 74 and the heating plate 1 is stronger.

[0051] like Figure 7 As shown, in the plate-shaped steam heating structure described in this embodiment, in some embodiments, the other end of the second spring terminal 74 is provided with a second notch 742. In this embodiment, by providing the second notch 742, the firmness of the connection between the second spring terminal 74 and the heating plate 1 is further enhanced, and the structural reliability is higher.

[0052] Preferably, the second notch 742 is in a U-shape, but may also be in other shapes, such as a triangle or a semicircle.

[0053] like Figure 2 and Figure 5 As shown, in some embodiments of the plate-shaped steam heating structure described in this embodiment, the second mounting plate 7 is provided with second holes 75 spaced apart along its length direction. In this embodiment, the second strip holes are provided on the second mounting plate 7 to dissipate the heat from the periphery of the heating plate 1 and avoid the heat from being concentrated between the second mounting plate 7 and the heating plate 1.
