[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Please refer to Figures 1 to 13 The present invention provides a water treatment device, including: a water guide component 10, on which a water outlet 100 is arranged; a high-voltage electrode 300 and a ground electrode 301, and a discharge gap is formed between the high-voltage electrode 300 and the ground electrode 301; a dielectric layer component 20, which is arranged in the discharge gap, and has a drainage part 200 connected to the water outlet 100, and the drainage part 200 extends along the extension direction of the discharge gap.

[0035] The water treatment device of the present invention comprises a water guide component 10, a high voltage electrode 300, a ground electrode 301 and a dielectric layer component 20, wherein a water outlet 100 is arranged on the water guide component 10, a discharge gap is formed between the high voltage electrode 300 and the ground electrode 301, and the dielectric layer component 20 is arranged in the discharge gap, and the dielectric layer component 20 has a drainage portion 200 connected to the water outlet 100, and the drainage portion 200 extends along the extension direction of the discharge gap.

[0036] Specifically, the water treatment device of the present invention is based on the DBD technology principle. Under high pressure, the electrode and the liquid surface form a gas-liquid mixed phase discharge area and form a plasma. Under high voltage discharge, the treated water will produce hydroxyl, nitrate ion, hydrogen peroxide ion and ozone, and chemical reaction will occur to produce hydrogen peroxide and peroxynitrate. Therefore, the activated water treated by plasma technology has a sterilization function. In this way, the water is directly discharged by plasma and a solution with sterilization and disinfection is prepared, which can directly sterilize the object to be sterilized.

[0037] In an embodiment of the present invention, the water treatment device also includes: a discharge reactor, the discharge reactor includes an electrode interface, and the motor interface includes a high-voltage wiring port 310 and a grounding wire port 311, so that when the high-voltage wiring port 310 and the grounding wire port 311 are connected to a power source and the voltage is increased, a discharge gap is formed between the high-voltage electrode 300 and the ground electrode 301.

[0040] like Figure 4 As shown, since creepage will break through the air or insulating material between the two electrodes, resulting in failure of normal discharge, a support flange 113 is provided on the second water guide plate 112, and the end of the dielectric layer assembly 20 is located between the support flange 113 and the peripheral plate 12; the water guide assembly 10 also includes a peripheral plate 12, and one end of the peripheral plate 12 protruding from the second water guide plate 112 is butted against the end of the high-voltage electrode 300, and one end of the support flange 113 away from the second water guide plate 112 is butted against the end of the ground electrode 301. In this way, along the distribution direction from the water guide assembly 10 to the dielectric layer assembly 20.

[0041] Specifically, the water guide component 10 includes a water guide component 11, which is arranged on the high-voltage electrode 300, the ground electrode 301 and one end of the dielectric layer component 20; the dielectric layer component 20 includes a first dielectric layer 21 and a second dielectric layer 22, the first dielectric layer 21 is connected to the high-voltage electrode 300, and the second dielectric layer 22 is connected to the ground electrode 301; wherein, one end of the first dielectric layer 21 close to the water guide component 11 protrudes from one end of the high-voltage electrode 300 close to the water guide component 11; and / or one end of the second dielectric layer 22 close to the water guide component 11 protrudes from one end of the ground electrode 301 close to the water guide component 11. To avoid creepage during discharge

[0042] In the embodiment of the present invention, the water guide assembly 10 further includes a water guide pipe 13 , and the water guide pipe 13 is in communication with the water inlet 103 .

The first water outlet 101 is connected to the first water channel 201 , and the second water outlet 102 is connected to the second water channel 202 .

[0044] The first water guide groove 201 and the second water guide groove 202 play a drainage role and ensure that water is discharged at the drainage location.

[0045] like Figures 5 to 7 As shown, the structure of the water guide assembly 10 designed by the present invention is to make water flow into the water guide groove more evenly. In the specific implementation process of the embodiment of the present invention, the water flow direction is from the water inlet 103 through the water guide space 110, and finally out of the first water outlet 101 and the second water outlet 102. Among them, the water flow in the first water outlet 101 flows to the first water guide groove 201, and the water flow in the second water outlet 102 flows to the second water guide groove 202.

[0047] In the specific implementation process of the embodiment of the present invention, in the absence of water, the discharge area is discharged between the first dielectric layer 21 and the second dielectric layer 22. After water is passed, the discharge area is preferentially discharged in the water area. The reason is that during the entire discharge process, water is in a suspended potential, that is, it is not directly in contact with the high-voltage electrode 300 or the ground electrode 301, but is between the two media. Under high pressure, water is equivalent to a conductive liquid and will preferentially discharge in places with stronger potentials. Therefore, the discharge area will preferentially discharge near the water guide groove, thereby achieving the effect of water treatment. The first dielectric layer 21 and the second dielectric layer 22 both have water guide grooves for drainage, which is beneficial to increase the discharge area of ​​activated water treatment to achieve water treatment efficiency.

[0048] The second medium layer 22 is disposed in the inner cavity of the first medium layer 21 , the first water guide groove 201 of the first medium layer 21 is located inside the first medium layer 21 , and the second water guide groove 202 of the second medium layer 22 is located outside the second medium layer 22 .

[0049] Specifically, the first medium layer 21 includes a plurality of gear-shaped first protrusions, two adjacent first protrusions form a first water channel 201 ; the second medium layer 22 includes a plurality of gear-shaped second protrusions, two adjacent second protrusions form a second water channel 202 .

[0052] Specifically, the cross section of the support seat 30 is circular.

[0053] In an embodiment of the present invention, the support seat 30 includes a support seat water inlet 31, which is arranged at the center of the support seat 30, so that the water in the water guide assembly 10 flows into the support seat water inlet 31 after flowing to the drainage portion 200 of the medium layer assembly 20. Specifically, the support seat water inlet 31 is used to limit the second medium layer 22, and the support seat water inlet 31 is connected to the water guide pipe 13.

[0054] In an embodiment of the present invention, the water treatment device also includes a shell 1, a water guide component 10 is arranged on the top of the shell 1, a support seat 30 is arranged on the bottom of the shell 1, and a dielectric layer component 20 and a high-voltage electrode 300 and a ground electrode 301 are all arranged in the cavity of the shell 1.

[0055] In summary, the present invention can effectively improve the discharge efficiency of a single water flow while ensuring the stability of the water flow, and the water flow in multiple water guide grooves can greatly speed up the efficiency of water treatment. The invention can provide technical support for later product development.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] The water treatment device of the present invention comprises a water guide component 10, a high voltage electrode 300, a ground electrode 301 and a dielectric layer component 20, wherein a water outlet 100 is arranged on the water guide component 10, a discharge gap is formed between the high voltage electrode 300 and the ground electrode 301, and the dielectric layer component 20 is arranged in the discharge gap, and the dielectric layer component 20 has a drainage portion 200 connected to the water outlet 100, and the drainage portion 200 extends along the extension direction of the discharge gap.
