The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Combine the following Figures 1 to 4 , describing an over-current electrolytic disinfection device according to an embodiment of the utility model.

[0031] A flow-through electrolytic disinfection device comprises a cover body 1, an intermediate flow-through tube 2 and a disinfection generating tank 3, wherein the cover body 1 is arranged on the top of the intermediate flow-through tube 2, and the bottom of the intermediate flow-through tube 2 is detachably connected to the top of the disinfection generating tank 3;

[0032] The middle flow tube 2 is provided with a water inlet channel 21 and a water outlet channel 22, and the water inlet channel 21 and the water outlet channel 22 are respectively connected to the disinfection generating tank 3;

[0033] A disinfection generator 31 is arranged in the disinfection generating tank 3 , and a disinfection electric control module 11 is arranged in the cover body 1 . The disinfection electric control module 11 is electrically connected to the disinfection generator 31 .

[0034] The over-flow electrolytic disinfection device of the utility model disinfects the water supply in an over-flow manner, has high disinfection efficiency, and can produce purified water as needed; since no water storage is required, a relatively small volume of the disinfection generating tank 3 can meet the demand for water supply disinfection, which greatly reduces the volume of the disinfection device and is conducive to the miniaturization of comprehensive oral treatment equipment. Exemplarily, the cover body 1, the middle over-flow cylinder 2 and the disinfection generating tank 3 are connected to form a cylindrical shape. Specifically, the over-flow electrolytic disinfection device of the utility model adopts a micro-electrolytic disinfection method, and the disinfection electronic control module 11 is used to control the start and stop of the disinfection generator 31.

[0035] It should be noted that the overflow electrolytic disinfection device of the present invention is preferably used in comprehensive dental treatment equipment, and can also be applied to other equipment that requires water disinfection, such as water dispensers.

[0036] In the prior art, the disassembly and assembly process of the top cover, the electrolysis cover and the electrolysis box is relatively cumbersome, and the cleaning operation of the electrolysis box and the maintenance and replacement of the devices in the electrolysis box are inconvenient. In the utility model, the intermediate flow cylinder 2 and the disinfection generating tank 3 can be detachably connected by means of threaded connection or snap connection. In order to facilitate the disassembly and assembly operation of the intermediate flow cylinder 2 and the disinfection generating tank 3, in a preferred embodiment, a plurality of connecting blocks 23 are arranged on the inner side of the lower edge of the intermediate flow cylinder 2, and a plurality of limiting blocks are arranged on the top of the disinfection generating tank 3; there is a vacancy 33 for inserting the connecting block 23 between two adjacent limiting blocks, and the bottom of the limiting block has a limiting space 34 for limiting the connecting block 23; the vacancy 33 and the limiting space 34 are connected.

[0037] When the intermediate flow tube 2 is assembled with the disinfection generating tank 3, the connecting block 23 is inserted into the empty space 33 between two adjacent limiting blocks 32, and then the intermediate flow tube 2 and the disinfection generating tank 3 are rotated relative to each other. Based on the connection between the empty space 33 and the limiting space 34, the connecting block 23 can slide into the limiting space 34 to achieve the connection between the intermediate flow tube 2 and the disinfection generating tank 3. When the intermediate flow tube 2 and the disinfection generating tank 3 are disassembled, the intermediate flow tube 2 and the disinfection generating tank 3 are rotated relative to each other, and the connecting block 23 is withdrawn from the limiting space 34 to the empty space 33 between two adjacent limiting blocks 32, so that the intermediate flow tube 2 and the disinfection generating tank 3 can be separated, and the operation is simple and convenient. Exemplary, the number of the connecting block 23 and the limiting block 32 is two or three.

[0038] Preferably, the disinfection generating tank 3 comprises a sleeved tank body 35 and a connecting tube 36 , the disinfection generator 31 is fixed to the bottom of the tank body 35 , and a limit block is located at the top of the connecting tube 36 to facilitate the disassembly and assembly of the disinfection generator 31 .

The water inlet channel 21 is located in the disinfection generating tank 3 based on the vertical pipe 221, and the water that has been disinfected in the lower part of the disinfection generating tank 3 can be discharged to ensure the purification degree of the water outlet. Moreover, the tail end of the water inlet channel 21 is adjacent to the tail end of the water outlet channel 22, which is convenient for setting the direction of the water inlet channel 21 and the water outlet channel 22. In a specific embodiment, the central axis of the water inlet channel 21 and the water outlet channel 22 is located in the same straight line, simplifying the structure of the intermediate flow cylinder 2. Specifically, a partition is provided in a pipeline that runs through the intermediate flow cylinder 2, and the pipeline is divided into the water inlet channel 21 and the water outlet channel 22, and the vertical pipe 221 is connected in the middle of the pipeline.

[0044] Preferably, a notch 222 is provided on one side of the vertical pipe 221 away from the tail end opening 211 of the water inlet channel 21 to achieve the effect of isolating the water inlet and the water outlet.

[0045] In order to facilitate the maintenance of the disinfection electronic control module 11 and the cleaning of the intermediate flow tube 2, the cover body 1 is detachably connected to the intermediate flow tube 2. Exemplarily, the inner wall of the intermediate flow tube 2 is provided with a limiting groove with an insertion notch 222, and the edge of the cover body 1 is provided with a card block, which enters the limiting groove from the insertion notch 222, and then the cover body 1 and the intermediate flow tube 2 are relatively rotated so that the limiting groove can limit the card block.

[0046] In order to facilitate the installation of the over-flow electrolytic disinfection device in the dental comprehensive treatment machine, the end of the water inlet channel 21 or the water outlet channel 22 located outside the middle flow tube 2 is sleeved with a mounting bracket 4; the outer wall of the cover body 1 is provided with a protrusion 12 that is inserted into the mounting bracket 4.
