UTILITY MODEL CONTENT

[0003] The utility model aims at the shortcomings of prior art, provide a kind of glass heating disc, it can effectively block intercept aluminum plate and welding material into hole center edge by the middle hole stainless steel flanging, to eliminate the risk of aluminum material and welding auxiliary material dilution into container.

[0004] To achieve the purpose, the technical scheme that the utility model adopts is as follows:

[0005] A kind of glass heating disc, including stainless steel plate and heating tube, the upper through-hole is formed in the middle of the stainless steel plate, the upper through-hole lower end is shaped with flanging, the stainless steel plate is equipped with aluminum plate between the heating tube, the lower through-hole is formed in the middle of the aluminum plate, the aluminum plate is welded with stainless steel plate after being sleeved with flanging by lower through-hole.

[0006] Preferably, the lower outer end between the flanging and the aluminum plate is formed with arc-shaped reinforcing ring.

[0007] Further preferably, the cross section of the flanging is L-shaped or C-shaped.

[0008] Further preferably, the lower outer end between the flanging and the aluminum plate is sleeved with elastic sleeve ring.

[0009] Further preferably, the lower outer end between the flanging and the aluminum plate is sleeved with elastic snap ring, one end of the elastic snap ring is provided with clamping convex, the other end of the elastic snap ring is provided with clamping groove matched with the clamping convex, the clamping convex is provided with convex column at both ends, and the clamping groove is provided with recess hole matched with the convex column at both sides of inner wall.

[0010] Compared with existing technologies, this invention includes a stainless steel plate and a heating element. The stainless steel plate has an upper through hole in the middle, and a flange is formed at the lower end of the upper through hole. An aluminum plate is placed between the stainless steel plate and the heating element, and the aluminum plate has a lower through hole in the middle. The aluminum plate is welded to the stainless steel plate after being fitted with the flange through the lower through hole. This invention effectively blocks the aluminum plate and welding materials from entering the center edge of the hole, thereby preventing the aluminum material and welding auxiliary materials from diluting and entering the container, and avoiding the risk of unsanitary water entering the container.

[0015] Figure 5 This is a partial enlarged view of Embodiment 4 of this utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1, as Figure 1 , 2 As shown, a glass heating plate includes a stainless steel plate 1 and a heating element. The stainless steel plate 1 has an upper through hole in the middle, and a flange 2 is formed at the lower end of the upper through hole. An aluminum plate 6 is provided between the stainless steel plate 1 and the heating element. The aluminum plate 6 has a lower through hole in the middle. The aluminum plate 6 is sleeved with the flange 2 through the lower through hole and then welded to the stainless steel plate 1. This utility model effectively blocks the aluminum plate 6 and welding materials from entering the center edge of the hole by opening a through hole and flange in the middle of the stainless steel plate 1, and then fitting the lower through hole of the aluminum plate 6 with the flange 2, and welding the aluminum plate 6 to the flange 2 of the stainless steel plate 1. This prevents the aluminum material and welding auxiliary materials from diluting and entering the container, and avoids the risk of unsanitary water entering the container.

[0018] Example 2, as Figure 3As shown in the embodiment, the lower outer end between the flange 2 and the aluminum plate 6 is provided with an arc-shaped reinforcing ring 3, and the cross section of the flange 2 is in L shape or C shape, so that the effect of preventing the aluminum plate 6 and the welding material from entering the center edge of the hole is further enhanced, and the risk of the aluminum material and the welding auxiliary material diluting into the container is eliminated.
