[0024] Example 1 Combination Figures 2 to 4 As shown, this embodiment provides an electronic anti-corrosion anode, which includes: an anode rod 10; a mounting connector 20, which is injection molded and fixed to the outer periphery of the anode rod 10; the mounting connector 20 is provided with a mounting end and a connecting end 210; an elastic sealing sleeve 30, which is sleeved on the connecting end 210 and sealed to the connecting end 210; the elastic sealing sleeve 30 is provided with a mounting hole 310, which is sealed to the anode rod 10.

[0025] Compared with the prior art, the present invention innovatively provides an elastic sealing sleeve 30 outside the connecting end 210 of the mounting joint 20. The elastic sealing sleeve 30 is sealed to both the anode rod 10 and the connecting end 210, thereby enhancing the sealing effect between the end of the mounting joint 20 and the anode rod 10 and preventing liquid from leaking through the gap between the end of the mounting joint 20 and the anode rod 10.

[0026] It should be noted that the applied current to the anode rod 10 suppresses the loss of electrons by the inner tank, thus providing good corrosion protection. The mounting connector 20 is used for installation and connection with the mounting base on the water heater. This is prior art in this field and will not be described in detail in this embodiment.

[0027] In this embodiment, the elastic sealing sleeve 30 can be connected and fixed to the mounting joint 20 by an adhesive to achieve a sealed connection between the elastic sealing sleeve 30 and the connecting end 210.

[0028] In this embodiment, at least one sealing layer 211 is provided between the connecting end 210 and the elastic sealing sleeve 30, and the sealing layer 211 is distributed along the length direction of the anode rod 10. Specifically, by providing the sealing layer 211, if the connection between the elastic sealing sleeve 30 and the mounting joint 20 fails, liquid will flow into the space between the elastic sealing sleeve 30 and the mounting joint 20 through the failure point. The liquid will be blocked by the sealing layer 211, preventing the liquid from flowing between the end and the anode rod 10, thus ensuring the sealing effect of the electronic anti-corrosion anode in this embodiment.

[0029] Regarding the structure and manufacturing of the sealing layer 211, further, at least one annular groove 212 is provided on the outer periphery of the connecting end 210, and liquid silicone is provided between the annular groove 212 and the inner wall of the elastic sealing sleeve 30 to form the sealing layer 211. Specifically, when manufacturing the electronic anti-corrosion anode of this embodiment, liquid silicone can be added to the annular groove 212 first, and then the elastic sealing sleeve 30 can be installed and the liquid silicone can be allowed to cure. In this embodiment, the sealing layer 211 can be formed between the annular groove 212 and the inner wall of the elastic sealing sleeve 30 by the above method.

[0030] Preferably, two sealing layers 211 are provided between the connecting end 210 and the elastic sealing sleeve 30, and correspondingly, two annular grooves 212 are provided on the outer periphery of the connecting end 210.

[0031] In this embodiment, the elastic sealing sleeve 30 is made of silicone material. The elastic properties of the elastic sealing sleeve 30 enable it to be sealed to the anode rod 10.

[0032] In this embodiment, the elastic sealing sleeve 30 is provided with a top abutment portion 320, which abuts against the end of the connecting end 210. In this embodiment, the position of the elastic sealing sleeve 30 is limited by the abutment portion 320 against the end of the connecting end 210.

[0033] Furthermore, the top abutment portion 320 is provided with the mounting hole 310, and the top abutment portion 320 has a certain thickness so that the mounting hole 310 has a corresponding certain length, so as to improve the sealing effect.

[0034] In this embodiment, the electronic anti-corrosion anode further includes an electronic anode contact 40, which is connected to the anode rod 10. The electronic anode contact 40 is exposed outside the mounting connector 20 so that the electronic anode contact 40 can be connected to the wires of the control device of the water heater.

[0035] Furthermore, the electronic anode contact 40 is provided with a collar 410, and one end of the anode rod 10 is inserted into the collar 410; the outer periphery of one end of the anode rod 10 is provided with anti-detachment stripes 110. In this embodiment, the anti-detachment stripes 110 contact the inner wall of the collar 410 to avoid insufficient friction caused by the smooth surface of the anode rod 10, and to ensure the connection stability between the anode rod 10 and the electronic anode contact 40.

[0036] In this embodiment, the electronic anti-corrosion anode may further include a sealing ring, which is sleeved on the mounting joint 20 and makes sealing contact with the mounting base. The sealing ring prevents water from leaking out from the gap between the mounting joint 20 and the mounting base.

[0037] Example 2 Combination Figures 5 to 6 As shown, a second aspect of this utility model is to provide an electronic anti-corrosion anode, comprising: an anode rod 10; a mounting connector 20, which is injection molded and fixed to the outer periphery of the anode rod 10; the mounting connector 20 having a mounting end and a connecting end 210; a sealing ring 50, which is sleeved on the anode rod 10 and sealed to the anode rod 10; a locking member 60, which has a through hole for the anode rod 10 to pass through; the locking member 60 is mounted and connected to the connecting end 210 to press the sealing ring 50 against the end of the connecting end 210.

[0038] Compared with the prior art, the present invention innovatively provides a locking member 60 outside the connection end 210 of the mounting joint 20. The locking member 60 presses the sealing ring 50 against the end of the connection end 210, enhances the sealing effect between the end of the mounting joint 20 and the anode rod 10, and prevents liquid from leaking through the gap between the end of the mounting joint 20 and the anode rod 10.

[0039] Furthermore, the outer periphery of the connecting end 210 is provided with an external thread, and the locking member 60 is provided with an internal thread; the locking member 60 is threadedly engaged with the connecting end 210 to realize the installation connection between the locking member 60 and the connecting end 210.

[0040] In this embodiment, the electronic anti-corrosion anode further includes an electronic anode contact 40, which is connected to the anode rod 10. The electronic anode contact 40 is exposed outside the mounting connector 20 so that the electronic anode contact 40 can be connected to the wires of the control device of the water heater.

[0041] Furthermore, the electronic anode contact 40 is provided with a collar 410, and one end of the anode rod 10 is inserted into the collar 410; the outer periphery of one end of the anode rod 10 is provided with anti-detachment stripes 110. In this embodiment, the anti-detachment stripes 110 contact the inner wall of the collar 410 to avoid insufficient friction caused by the smooth surface of the anode rod 10, and to ensure the connection stability between the anode rod 10 and the electronic anode contact 40.

[0042] In this embodiment, the electronic anti-corrosion anode may further include a sealing ring, which is sleeved on the mounting joint 20 and makes sealing contact with the mounting base. The sealing ring prevents water from leaking out from the gap between the mounting joint 20 and the mounting base.

[0043] Example 3 Combination Figure 7 As shown, in this embodiment, the mounting end 220 of the mounting connector is provided with an external thread section 221 and a sealing ring 222; when the electronic anti-corrosion anode is installed and connected to the inner tank of the electric water heater, the sealing ring 221 is located inside the inner tank, relative to... Figure 1 The existing technology, which uses a sealing ring located outside the inner liner, is shown in this embodiment. This embodiment enables a sealed connection between the electronic anode and the inner liner, resulting in better leak prevention.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
