[0021] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] In this utility model, such as Figures 1 to 4As shown, a water disinfection machine is provided, comprising: a housing 1 having a receiving cavity; two electrolytic cells 2 disposed within the receiving cavity, wherein the inlet of one electrolytic cell 2 is connected to an inlet pipe 3, the outlet of one electrolytic cell 2 is connected to the inlet of the other electrolytic cell 2, and the outlet of the other electrolytic cell 2 is connected to an outlet pipe 4; a flow sensor 5 installed on the inlet pipe 3; and a circuit board 6 electrically connected to the flow sensor 5 and the electrolytic cell 2.

[0026] In use, the water disinfection machine of this utility model uses circuit board 6 to monitor the water flow rate in the water pipe via flow sensor 5. When the water flows through electrolysis cell 2, the water is disinfected by electrolysis and then flows out through outlet pipe 4. In a specific embodiment, by setting two electrolysis cells 2, when the water flow rate is large (exceeding a set threshold), both electrolysis cells 2 can be activated simultaneously for efficient electrolytic disinfection of the water flow. When the water flow rate is small (below the set threshold), only one electrolysis cell 2 can be activated to reduce power consumption. This utility model, through such a setting, can adjust to different flow rate requirements of the water supply circuit to ensure disinfection effect.

[0027] Of particular importance is that this utility model, by setting up a housing 1, can integrate the electrolytic cell 2, circuit board 6, water inlet pipe 3, and water outlet pipe 4 into the housing 1. In the dental water system, only the water inlet pipe 3 and water outlet pipe 4 need to be connected, which facilitates the installation and disassembly of the sterilizer and also provides protection.

[0030] In the specific embodiment shown in the figure, the two electrolytic cells 2 are located at the upper end of the housing 1, and the water inlet pipe 3 and the water outlet pipe 4 are led out from the lower end of the housing 1, so as to optimize the use of the space inside the housing 1 in the vertical direction.

[0031] In a preferred embodiment, specifically regarding the structure of this utility model, the housing 1 is provided with fixing ear plates 7 at one end near the electrolytic cell 2 and at the other end near the outlet of the water inlet pipe 3 and the water outlet pipe 4, respectively.

[0034] In a preferred embodiment, more specifically regarding the structure of this utility model, the circuit board 6 is mounted on the first housing 101.

[0035] In a preferred embodiment, the structure of the present invention is further described as follows: the first housing 101 includes a shell plate, the edge of which forms a side ring 10, and the second housing 102 is fastened to the side ring 10; the water inlet connector 8 and the water outlet connector 9 are installed on the side ring 10.

[0036] As shown in the figure, a side ring 10 is provided in the first housing 101 to facilitate the fixing of the water inlet connector 8 and the water outlet connector 9.

[0037] In a preferred embodiment, specifically regarding the structure of this utility model, the first housing 101 and the second housing 102 are snapped together, as shown below. Figure 2 and 4 As shown, the side ring 10 is provided with a hook, and the second housing 102 is provided with a buckle, so that the first housing 101 and the second housing 102 can be directly snapped together during assembly, which is convenient for disassembly and assembly.

[0038] In a preferred embodiment, more specifically regarding the structure of this utility model, the circuit board 6 is disposed on the side of the electrolytic cell 2 facing the second housing 102.

[0039] As shown in the figure, the circuit board 6 is connected to the bottom plate of the first housing 101 by screws. By setting the circuit board 6 on the side of the electrolytic cell 2 facing the second housing 102, the lateral space inside the housing 1 can be optimized.
