Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to a probe anode sealing structure for water heaters. Background Technology

[0002] A water heater is a device that heats the liquid in a water tank to different temperatures by burning gas or heating it with electricity. According to its heating method, it can be divided into gas water heaters, electric water heaters, solar water heaters, etc. In order to know the liquid temperature inside the water heater tank in time, most water heater devices are equipped with probes.

[0003] To prevent the anode inside the water heater probe from dislodging from its original position, a sealing structure is needed to fix it. However, the previous sealing structure only injected adhesive into the sleeve to prevent the anode rod from shaking or falling off. This could not guarantee the verticality of the anode rod, and it was also inconvenient to remove the anode rod after the adhesive solidified.

[0004] Now, a novel probe anode sealing structure for water heaters is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a probe anode sealing structure for water heaters to solve the problem of inconvenient installation and disassembly of anode rods mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a probe anode sealing structure for a water heater, comprising a sleeve, a transverse groove provided between the left and right sides inside the sleeve, an inner tube fixedly inserted into the left side of the transverse groove, an inner cavity provided between the left and right sides inside the inner tube, an insulating sleeve fixedly connected to the right side inside the transverse groove, an anode rod horizontally fixed between the inner tube and the insulating sleeve, a left annular groove provided on the left side inside the insulating sleeve, an O-ring seal ring one fixed in the left annular groove, a right annular groove provided on the right side outside the insulating sleeve, an O-ring seal ring two fixed in the right annular groove, a threaded groove provided on the left side outside the sleeve, and a sleeve block fixed on the right side outside the sleeve.

[0007] As a further technical solution of this utility model, the left annular groove matches the specifications of O-ring one, and the right annular groove matches the specifications of O-ring two.

[0008] As a further technical solution of this utility model, a slot is provided on the right side of the transverse groove, and an insert block is fixed in the slot. A limiting ring is fixed on the left side of the insert block, and a spring retainer is fixed between the limiting ring and the slot. The right side of the anode rod is embedded between the insulating sleeve and the insert block.

[0009] As a further technical solution of this utility model, the insert block, the limiting ring and the spring retainer are arranged in concentric circles, and the spring retainer bounces left and right between the limiting ring and the slot.

[0010] As a further technical solution of this utility model, a screw is threadedly connected between the center of the insert block and the anode rod, and a locking piece is sleeved on the right side of the screw, with a nut attached to the right side of the locking piece.

[0011] As a further technical solution of this utility model, the nut is threaded onto the outside of the screw rod, and the inner wall of the nut matches the outer wall of the screw rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the probe anode sealing structure for water heaters not only achieves stable installation and disassembly of the anode rod and tight sealing of the internal left and right accessories, but also achieves firm locking of the anode rod;

[0013] (1) An inner tube is fixedly inserted into the inside of the left side of the transverse groove. The inner tube and the insulating sleeve are filled on the left and right sides of the sleeve respectively. The anode rod is fixed between the two. The left side of the inner side of the insulating sleeve contacts the anode rod with an O-ring seal one, and the right side of the outer side of the insulating sleeve contacts the sleeve with an O-ring seal two. This object is firmly locked between the inner tube and the insulating sleeve. No glue is needed. It is convenient to assemble and disassemble, and ensures the verticality of the anode rod.

[0014] (2) By fixing a spring retainer between the limiting ring and the slot, when the insert is inserted into the sleeve from the right side, the spring retainer is first inserted into the left side of the slot, and then the insert is sealed and fixed on the right side of the insulating sleeve. The elastic spring retainer presses the insulating sleeve to the left, and the insulating sleeve is pressed against the right side of the inner tube to prevent the inner tube from detaching from the sleeve. It also stabilizes the anode rod in the sealing structure. Each part can be disassembled and reassembled.

[0015] (3) A screw is threaded between the center of the insert and the anode rod. After assembling the inner tube, insulating sleeve, insert and anode rod inside the sleeve, screw is screwed in laterally from the right side. Then, a locking piece is put on the right side of the screw. Continue to rotate the nut to press the locking piece against the screw and lock the right side of the screw in the insert. This improves the internal structural strength of the sealing fitting and prevents the anode rod from shaking. Attached Figure Description
