[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1 to 5 As shown, an all-glass kettle with integrated water temperature detection includes a glass kettle body 1, a bottom shell 2, and a heating plate 3. The heating plate 3 is placed on the outer bottom surface of the glass kettle body 1. The bottom shell 2 is connected to the bottom of the glass kettle body 1 and surrounds the heating plate 3 therein. A handle 4 is fastened to the side wall of the glass kettle body 1. A thin film patch 5 is provided at the connection and contact position between the handle 4 and the glass kettle body 1. A water level detection element and a temperature sensing element 6 are provided on the thin film patch 5. The sensing planes of the water level detection element and the temperature sensing element 6 are tightly attached to the outer surface of the glass kettle body 1. This all-glass kettle integrates water level and temperature detection functions onto a thin film patch 5 attached to the outer surface of the glass kettle body 1. This ensures the integrity of the glass kettle body 1, eliminates the need for opening holes in the bottom of the glass kettle body 1, and prevents damage to the glass kettle body 1 caused by dry boiling.

[0022] The thin-film patch 5 extends along the height of the glass kettle body 1. The water level detection element includes a low water level detection element 7 and a high water level detection element 8. The low water level detection element 7 is located at the lower end of the thin-film patch 5, and the high water level detection element 8 is located at the top end of the thin-film patch 5. When the water level detection element has both high and low water level detection, it can prevent the user from adding water beyond the maximum water level line and prevent overflow when the water boils. This allows the thin-film patch 5 to have three functions simultaneously, improving production efficiency during kettle installation.

[0023] The bottom of the glass pot body 1 is provided with an inwardly recessed annular groove 101, which is located on the lower side of the thin film patch 5. A flexible conveyor belt 51 is connected to the bottom of the thin film patch 5, and the temperature sensing element 6 is located on the flexible conveyor belt 51 and is bent into the annular groove 101 through the flexible conveyor belt 51, so that the temperature sensing element 6 is in close contact with any groove wall of the annular groove 101. The temperature sensing element 6 is electrically connected to the flexible conveyor belt 51, so that the temperature sensing element 6 can be attached to the uneven outer surface of the glass pot body 1. Moreover, the installation angle of the temperature sensing element 6 can be changed, making the arrangement more flexible and convenient, and reducing the space occupied by the handle 4.

[0024] A film support is also provided at the corresponding connection and fitting position of the handle 4. The film patch 5 is tightly fitted to the outer surface of the glass pot body 1 by the pressure of the film support. Specifically, the film support includes a silicone plate 9 adapted to the size of the film patch 5. The inner side wall of the handle 4 is provided with a positioning and mounting groove 401. The silicone plate 9 is fixed in the positioning and mounting groove 401. The handle 4 is fastened to the glass pot body 1, so that the silicone plate 9 is elastically pressed against the film patch 5. The elasticity of the silicone plate 9 allows the pressure applied by the handle 4 to the film patch 5 to be evenly distributed. It can also flexibly avoid the protruding low water level detection element 7 and high water level detection element 8, ensuring that the film patch 5 is tightly attached to the surface of the glass pot body 1. This provides sufficient support for the film patch 5, so that the installation of the film patch 5 does not require the use of glue or other materials for fixing, and prevents the film patch 5 from sliding down.

[0025] The handle 4 includes a handle base 41 that is connected and fitted to the glass pot body 1 and a handle portion 42 connected to the handle base 41. The upper and / or lower part of the handle portion 42 is provided with a wire passage 421, and the gripping position of the handle portion 42 is provided with a mounting cavity 422. The mounting cavity 422 is provided with a wire control board 10. The wire control board 10 is electrically connected to the film patch 5 through a wire passing through the wire passage 421. The control board 10 is placed inside the mounting cavity 422 to facilitate the assembly and connection of the control board 10. Specifically, the handle base 41 and the handle part 42 are integrally made of the outer shell. A handle cover 43 is connected to the outer side of the handle part 42. The outer shell and the handle cover 43 together define the mounting cavity 422. The removal and installation of the handle cover 43 can open the mounting cavity 422, thereby facilitating the insertion and fastening of the control board 10. Moreover, the control board 10 placed inside the mounting cavity 422 also serves as a heat insulation between itself and the glass pot body 1, preventing the heat radiated by the glass pot body 1 from affecting the operation of the control board 10.

[0026] A fastening ring 11 connected to the heating plate 3 is sleeved inside the annular groove 101. An elastic support member 112 is provided on the fastening ring 11 corresponding to the temperature sensing element 6. The elastic support member 112 pushes against the temperature sensing element 6, so that the sensing plane of the temperature sensing element 6 is elastically and tightly attached to the upper groove wall 102 of the annular groove 101. By using the elastic support member 112 to support the temperature sensing element 6, it can be ensured that the temperature sensing element 6 can be tightly attached to the upper groove wall 102, thus ensuring the accuracy of temperature sensing. In addition, the temperature sensing element 6 is arranged in the annular groove 101, so that there is no need to open an avoidance opening on the heating plate 3 to avoid the sensing plane of the temperature sensing element 6, so that the heating plate 3 can remain intact and improve the heat transfer efficiency of the heating plate 3 to the glass kettle body 1; after the bottom shell 2 is installed at the bottom of the glass kettle body 1, the temperature sensing element 6 can be hidden inside, making the electric kettle more compact, simple and beautiful in appearance.

[0027] The fastening ring 11 includes a fastening body 111 with a break in it. An elastic support 112 is provided at the break in the break in the ring. The two ends of the fastening body 111 are fastened together by the elastic support 112. Specifically, the elastic support 112 includes a silicone connecting block 113. The two ends of the fastening body 111 are connected to the silicone connecting block 113. The top surface of the silicone connecting block 113 extends a support boss 114 that extends above the break in the break in the ring. The support boss 114 abuts against the temperature sensing element 6 and is in close contact with the upper groove wall 102 of the annular groove 101. The elastic support 112 is made entirely of silicone, which connects both ends of the fastening body 111. This allows the fastening body 111 to act as a buffer when tightened, preventing the glass pot 1 from cracking or exploding due to excessive tightening. In addition, the elasticity of the silicone allows the temperature sensing element 6 to elastically press against the upper groove wall 102.

[0028] Both ends of the fastening body 111 are provided with connecting parts 116 corresponding to the cut ends. The connecting parts 116 are provided with external connecting holes 117. The silicone connecting blocks 113 are provided with internal connecting holes 118 on both sides corresponding to the external connecting holes 117. By passing the two fastening units through the external connecting holes 117 and the internal connecting holes 118 respectively, the fastening body 111 is tightened and fixed in the annular groove 101.

[0029] A metal support ring 12 is provided on the lower side of the fastening ring 11. The hollow part of the metal support ring 12 is used for the heating tube in the heating plate 3 to protrude downward. The edge of the plate in the heating plate 3 abuts against the top of the metal support ring 12. After the metal support ring 12 is tightly connected to the fastening ring 11, the heating plate 3 is supported to be close to the outer bottom surface of the glass pot body 1. The heating plate 3 is tightly attached to the bottom surface of the heating plate 3 by the connection between the metal support ring 12 and the fastening ring 11. The structure is simple, the assembly efficiency is high, and the production cost is reduced. The metal support ring 12 forms a circumferential support for the heating plate 3, which enables the top surface of the heating plate 3 to be evenly attached to the bottom of the glass pot, reducing the gap between the bottom of the glass pot and the heating plate 3, and making the heat transfer efficiency between the two better.

[0030] Specifically, the fastening ring 11 has several downwardly extending first connecting protrusions 115 circumferentially, and the metal support ring 12 has a second connecting hole 121 corresponding to the first connecting protrusions 115. The metal support ring 12 is tightly connected to the fastening ring 11 by passing the fastening screw from bottom to top through the second connecting hole 121 and the first connecting hole.

[0031] In addition, the fastening ring 11 is also fastened to the bottom shell 2 by other connecting protrusions and other structures. The bottom surface of the heating plate 3 is equipped with an upper coupler 13. The upper coupler 13 is provided with an anti-dry burning device that abuts against the heating plate 3. The bottom shell 2 has an avoidance opening corresponding to the upper coupler 13. The above structure belongs to the prior art and will not be described in detail here.
