Description

Technical Field

[0001] This application relates to the technical field of floor scrubbers, and in particular to a wastewater tank electrolysis device. Background Technology

[0002] Floor scrubbers typically come with a clean water tank and a wastewater tank. The wastewater tank stores the drained wastewater, which provides a favorable environment for bacterial growth and reproduction. If cleaning is inadequate, bacteria levels can exceed safe limits, posing a potential health threat to users and contradicting the original design purpose of floor scrubbers. Therefore, our company has developed a device for sterilizing and disinfecting the wastewater tank of floor scrubbers and has applied for a related patent. The patent publication number is CN221319532U, which discloses a wastewater tank electrolytic disinfection device, including a housing; electrical contacts disposed in the housing and electrically connected to a power source; and an electrode plate unit electrically connected to the electrical contacts and located inside the wastewater tank to electrolyze the water in the wastewater tank to generate ozone when energized.

[0003] Regarding the aforementioned technologies, the inventors discovered that in actual production, the electrolytic disinfection device is directly connected to the sewage tank. However, the sewage in the tank contains many impurities, which can easily cause the impurities to conduct electricity and burn, resulting in a decrease in electrolysis efficiency and failing to meet the requirement of generating ozone for sterilization. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a wastewater tank electrolysis device, which has the advantage of reducing the impact of wastewater impurities on electrolyzed water, thereby ensuring the electrolysis sterilization effect.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A wastewater tank electrolysis device includes a housing, an inlet and an outlet on the housing, a filter assembly on the inlet, and an electrolysis assembly inside the housing. The filter assembly includes a filter sleeve screwed onto the water inlet, and the filter sleeve has an inclined downward drain outlet on its side wall, with the filter screen inclined toward the drain outlet. The filter assembly includes an anode plate disposed within a housing, and two cathode plates disposed on both sides of the anode plate; the housing is provided with power supply harness terminals for supplying power to the anode plate and the cathode plates.

[0006] To achieve the above technical solution, a portion of the wastewater can enter the shell through the inlet and be electrolyzed by the water electrolysis component inside the shell to generate ozone. This ozone, along with the remaining wastewater, is then discharged directly into the wastewater tank through the outlet, thereby sterilizing and disinfecting the wastewater in the tank. The filter sleeve has a downward-sloping drain outlet on its side wall, and the filter screen is angled towards the outlet, allowing a large portion of the wastewater to be discharged directly through the outlet without filtration, ensuring normal wastewater discharge. After connecting the filter sleeve to the wastewater pipe, a portion of the wastewater passes through the filter screen and enters the shell for electrolysis, reducing the likelihood of impurities affecting the water electrolysis process.

[0007] As a preferred embodiment of this application, the cathode plate is provided with a plurality of vent holes.

[0008] The above technical solution ensures that the ozone and other gases produced by water electrolysis can be discharged smoothly, and that the water can flow normally and smoothly.

[0009] As a preferred embodiment of this application, the housing includes a bottom shell and an upper cover fastened to the bottom shell, and the water inlet, water outlet, filter assembly and water electrolysis assembly are all disposed on the upper cover.

[0010] The above technical solution is achieved by making the housing itself detachable, so that the top cover can be removed to clean or replace the water electrolysis components, thereby ensuring the effectiveness of subsequent electrolysis disinfection.

[0011] As a preferred embodiment of this application, the upper cover is provided with a snap-fit ​​groove for snapping the cathode plate and the anode plate together, and the snap-fit ​​groove is provided with an elastic metal contact, which is electrically connected to the power supply harness terminal.

[0012] To achieve the above technical solution, it is only necessary to press the anode plate or cathode plate into the corresponding snap-fit ​​groove, and then the anode plate and cathode plate will contact the elastic metal contacts in their respective snap-fit ​​grooves to achieve electrical conduction. This allows the anode plate and cathode plate to be disassembled and replaced to ensure the electrolysis function.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. A portion of the wastewater enters the casing through the inlet and is electrolyzed by the water electrolysis component inside the casing to generate ozone. This ozone, along with the remaining wastewater, is discharged directly into the wastewater tank through the outlet, thus sterilizing and disinfecting the wastewater in the tank. The filter sleeve has a downward-sloping drain outlet on its side wall, and the filter screen is tilted towards the drain outlet, allowing a large portion of the wastewater to be discharged directly through the drain outlet without being filtered by the filter screen, thus ensuring the normal discharge of wastewater. After connecting the filter sleeve to the wastewater pipe, a portion of the wastewater passes through the filter screen and enters the casing for electrolysis, thereby reducing the entry of impurities that may affect the electrolysis of water.

[0018] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0019] This application discloses a wastewater tank electrolysis device. (Refer to...) Figure 1 A wastewater tank electrolysis device includes a housing 1, with an inlet 11 and an outlet 12. A filter assembly 2 is installed on the inlet 11, and an electrolysis assembly is installed inside the housing 1. A portion of the wastewater generated by the floor scrubber enters the housing 1 through the inlet 11, where it is electrolyzed by the electrolysis assembly to produce ozone. This ozone, along with the remaining wastewater, is then discharged into the wastewater tank through the outlet 12, thereby sterilizing and disinfecting the wastewater in the tank.

[0020] The housing 1 includes a bottom shell 13 and a top cover 14 fastened to the bottom shell 13. The water inlet 11, water outlet 12, filter assembly 2, and water electrolysis assembly are all mounted on the top cover 14. That is, the housing 1 itself is detachable, so that the top cover 14 can be removed to clean or replace the water electrolysis assembly, thereby ensuring the effectiveness of subsequent electrolysis disinfection.

[0021] The filter assembly 2 includes a filter sleeve screwed onto the inlet 11, and a filter screen is installed inside the filter sleeve. This allows the filter sleeve to be connected to a sewage pipe, so that a portion of the sewage passes through the filter screen before entering the housing 1 for electrolysis, thereby reducing the entry of impurities that could affect the electrolysis of water. The filter sleeve has a downward-sloping drain outlet on its side wall, and the filter screen is angled towards the drain outlet, allowing a large portion of the sewage to be discharged directly through the drain outlet without needing to pass through the filter screen, thus ensuring normal sewage discharge.

[0022] The filter assembly 2 includes an anode plate disposed within the housing 1, and two cathode plates disposed on either side of the anode plate. The housing 1 is equipped with power supply terminals for supplying power to the anode and cathode plates. Specifically, the positive and negative terminals of an external power source are connected to the anode and cathode plates via these terminals, thereby achieving the effect of supplying power to the anode and cathode plates for water electrolysis. Simultaneously, because both the anode and cathode plates are large-volume plates, this ensures sufficient electrolysis area while preventing impurities from completely covering the plates and causing electrolysis failure. Several vent holes are provided on the upper part of the cathode plates on both sides to ensure that ozone and other gases produced during water electrolysis can be smoothly discharged, and to ensure that the water can flow normally and smoothly. The upper cover 14 is provided with a snap-fit ​​groove for the cathode plate and the anode plate to snap together. The snap-fit ​​groove is provided with an elastic metal contact. The elastic metal contact is electrically connected to the power supply harness terminal. This means that after the anode plate or the cathode plate is pressed into the snap-fit ​​groove, the anode plate and the cathode plate contact the elastic metal contact in their respective snap-fit ​​grooves, thereby realizing power connection. This allows the anode plate and the cathode plate to be disassembled and replaced to ensure the electrolysis function.

[0023] The implementation principle of the wastewater tank electrolysis device in this application embodiment is as follows: a portion of the wastewater enters the housing 1 through the inlet 11 and is electrolyzed by the electrolysis component in the housing 1 to generate ozone, which is then discharged into the wastewater tank through the outlet 12 along with the remaining wastewater, thereby sterilizing and disinfecting the wastewater in the wastewater tank; wherein the filter sleeve is provided with an inclined downward drain outlet on its side wall, and the filter screen is inclined towards the drain outlet, so that a large portion of the wastewater does not need to be filtered by the filter screen and is discharged directly through the drain outlet, thereby ensuring the normality of wastewater discharge; after the filter sleeve is connected to the wastewater pipe, a portion of the wastewater enters the housing 1 after being filtered by the filter screen and is electrolyzed, thereby reducing the occurrence of impurities entering and affecting the electrolysis of water.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
