To prevent the heating element from burning out the inner tank and to avoid overheating and damaging other components in contact with it, the heating element is suspended after installation. However, during transportation, the suspended heating element cannot be properly secured and will shake. This not only loosens the installation but also causes the heating element to collide with the inner tank wall, damaging it. Furthermore, the damaged area may oxidize and rust, leading to metal leaching and water contamination. Utility Model Content

[0027] The following will be described in detail Figs. 1 to 3This invention describes an anti-collision electric heating tube according to an embodiment of the present invention, comprising a flange seat 1, an electric heating tube 2, and a plurality of anti-collision components 3, wherein the electric heating tube 2 is fixedly disposed on one side of the flange seat 1; and the plurality of anti-collision components 3 are respectively arranged on the electric heating tube 2.
[0028] The anti-collision component 3 includes a first clamping plate 31, a second clamping plate 32, and an anti-collision block 33;
[0029] The first clamping piece 31 is disposed above the electric heating tube 2, and the second clamping piece 32 is disposed below the electric heating tube 2;
[0030] The first clamping plate 31 and the second clamping plate 32 are connected by a connector 34. One end of the first clamping plate 31 and one end of the second clamping plate 32 clamp one of the heating tubes of the electric heating tube 2, and the other end of the first clamping plate 31 and the other end of the second clamping plate 32 clamp the other heating tube of the electric heating tube 2.
[0031] The anti-collision block 33 is disposed below the second clamping piece 32.
[0032] Specifically, in existing technology, the heating element is installed inside the inner tank. The heating element needs to heat the water and cannot contact the inner tank wall. To prevent the heating element from burning out the inner tank and to avoid excessively high temperatures that could damage other components in contact with the inner tank, the heating element is suspended after installation. However, during transportation, the suspended heating element cannot be fixed and will shake, causing not only loosening of the installation but also collisions with the inner tank wall, resulting in damage to the inner tank wall. This can also lead to metal oxidation and rust at the damaged area, and metal leaching that pollutes the water. In this embodiment, an anti-collision component 3 is installed on the heating element 2, clamping the heating element at both ends of the first clamping piece 31 and the second clamping piece 32. The two heating tubes 2 are fixed by a first clamping plate 31 and a second clamping plate 32 via a connector 34, which can be a bolt or other connecting component. This connector 34 also secures the anti-collision block 33, preventing it from loosening. The anti-collision block 33 is positioned below the second clamping plate 32, between the inner wall and the electric heating tube 2. During transportation, the anti-collision block 33 can fit tightly against the inner wall, providing support and positioning for the electric heating tube 2. Even if there is shaking or collision, the electric heating tube 2 will not collide with the inner wall. Furthermore, the anti-collision block 33 is made of an anti-collision elastic material, so the inner wall will not be damaged when it collides with the inner wall, effectively protecting the inner wall from damage and further preventing metal oxidation, rust, and metal leaching that could pollute the water.
[0033] Further, two ends of the first clamping sheet 31 are respectively provided with positive arc clamping parts 311, two ends of the second clamping sheet 32 are respectively provided with reverse arc clamping parts 321, the positive arc clamping parts 311 and the reverse arc clamping parts 321 are respectively sleeved on the upper and lower sides of the heating tube body of the electric heating tube 2, and the heating tube body of the electric heating tube 2 is limitedly arranged between the positive arc clamping parts 311 and the reverse arc clamping parts 321.
[0034] Specifically, in the embodiment, the positive arc clamping part 311 of the first clamping sheet 31 arranged on the upper side is downwardly sleeved on the upper side of the heating tube body of the electric heating tube 2, the reverse arc clamping part 321 of the second clamping sheet 32 arranged on the lower side is upwardly sleeved on the lower side of the heating tube body of the electric heating tube 2, so that the positive arc clamping part 311 and the reverse arc clamping part 321 tightly abut on the outer wall of the heating tube body, the connection is more closely, the connection structure of the anti-collision assembly 3 is more stable, and the problem of loosening of the anti-collision assembly 3 is effectively avoided.
[0035] Further, the middle part of the first clamping sheet 31 is provided with a positive buffer part 312, the positive buffer part 312 is upwardly arranged in an arch shape, the middle part of the second clamping sheet 32 is provided with a reverse buffer part 322, the reverse buffer part 322 is downwardly arranged in an arch shape, and a buffer cavity 30 is formed between the positive buffer part 312 and the reverse buffer part 322.
[0036] Specifically, in the embodiment, the first clamping sheet 31 and the second clamping sheet 32 are made of elastic metal and have a certain metal elasticity, the buffer cavity 30 is formed between the positive buffer part 312 and the reverse buffer part 322, and if shaking occurs during transportation and the anti-collision block 33 collides with the inner container wall, the anti-collision block 33 drives the second clamping sheet 32 to be pressed in the direction of the first clamping sheet 31, at this time, the metal elasticity is utilized to make the buffer cavity 30 play a buffering role, which helps to reduce the collision force between the anti-collision block 33 and the inner container wall, thereby better protecting the inner container.
[0037] Further, the anti-collision block 33 is provided with a bolt hole 331, the first clamping sheet 31 and the second clamping sheet 32 are respectively provided with mounting holes 301, and the anti-collision block 33 is connected through the bolt hole 331 and the mounting hole 301.
[0038] Specifically, in the embodiment, the anti-collision block 33 is installed through a bolt, the bolt is inserted into the bolt hole 331, then the bolt is screwed, the bolt is threadedly connected with the mounting hole 301 of the second clamping sheet 32 or the first clamping sheet 31, and the anti-collision block 33 can be installed and fixed, which is simple and convenient and has higher replacement and maintenance efficiency.
[0039] Furthermore, the bottom of the anti-collision block 33 is provided with a bolt mounting groove 332.
[0040] Specifically, in this embodiment, the bolt is installed in the bolt mounting groove 332, so that the bolt will not protrude from the surface of the anti-collision block 33, thus avoiding the bolt from colliding with the inner liner wall and further protecting the inner liner.
[0041] Furthermore, the anti-collision block 33 is made of an elastic material.
[0042] Specifically, in this embodiment, the anti-collision block 33 is made of an elastic material, preferably silicone. Silicone not only has good elasticity, but also high heat resistance and a longer service life.
[0043] This application also proposes an electric water heater that uses the aforementioned anti-collision heating tube, and further includes an outer shell 100 and an inner tank 200. The flange seat 1 of the anti-collision heating tube is installed at one end inside the inner tank 200, and the inner tank 200 is installed inside the outer shell 100.
[0044] Specifically, in this embodiment, during transportation, the electric water heater equipped with the anti-collision heating element can be supported and positioned by the anti-collision block 33. Even if shaking or collision occurs, the electric heating element 2 will not collide with the inner tank 200 wall, and the collision between the anti-collision block 33 and the inner tank 200 wall will not cause damage to the inner tank 200. This effectively protects the inner tank 200 from damage, further avoiding the problem of metal oxidation, rust, and metal precipitation that pollutes the water quality, thereby improving the service life of the electric water heater and the safety of the water quality.
