Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, embodiment 1 is provided, which is an electrolyzed water assembly according to a preferred embodiment of the present invention, and includes a housing 900, the housing 900 has an electrolysis chamber 901, and the housing 900 is provided with a water inlet 902 and a water outlet 903 which are communicated with the electrolysis chamber 901.

A membrane-electrode structure body 123 is arranged in the electrolytic chamber 901, the membrane-electrode structure body 123 includes a first electrode 100 and a second electrode 300 arranged opposite to the first electrode 100, wherein the first electrode 100 and the second electrode 300 are arranged in parallel and opposite to each other, a plate space 700 is formed between the first electrode 100 and the second electrode 300, that is, the first electrode 100 and the second electrode 300 are arranged at an interval, the plate space 700 is formed between the first electrode 100 and the second electrode, and the conductive film 200 is rotatably arranged in the plate space 700, that is, the conductive film 200 is configured to be movable, specifically, the conductive film 200 is stationary in a non-use state, and in a use state, the conductive film 200 is rotated under the pushing of water flow.

The membrane-electrode structure 123 is formed with a water flow channel for water to pass through, and the water flow channel is communicated with the water inlet 902 and the water outlet 903. Specifically, the membrane-electrode structure 123 is a structure in which an electrode and the conductive film 200 are stacked or spaced apart from each other, and a water flow channel is formed in the structure, in other words, a space of a water flow path through which water flows, such as a notch, a groove, the first through hole 101, a gap, and the like, is formed between the electrode and the conductive film 200, and the membrane-electrode structure 123 electrolyzes the water to generate electrolyzed water in the water flow channel.

For example, the polar space 700 formed between the first electrode 100 and the second electrode 300 forms part or all of the water flow channel, and the water body at least partially circulates and is electrolyzed at the polar space 700.

According to the electrolytic water assembly provided by the invention, when water flow is arranged to wash in the water flow channel, the conductive film 200 is pushed to rotate through the convex part 210 and the groove 220 of the conductive film 200, the conductive film 200 is prevented from accumulating scale on the surface of the conductive film 200 through rotation of the conductive film, meanwhile, the water body rotates to wash the first electrode 100 in the rotating process of the conductive film 200, the scale is prevented from accumulating on the surface of the first electrode 100, and the scale is discharged through driving of the water body, so that the service lives of the conductive film and the electrode plate are prolonged, on the other hand, the water receiving area of the conductive film 200 is increased, the electrolytic efficiency is correspondingly increased, and the concentration of electrolytic water is increased.

In the present invention, the conductive film 200 rotates in the plate space 700, it should be understood that at least a portion of the conductive film 200 is fixed so that the conductive film 200 rotates in the water flow channel but does not deviate in the water flow channel, for example, the conductive film 200 is limited in the axial center (or the center of the conductive film 200), for example, a positioning protrusion 910 is formed on the sidewall of the electrolytic chamber 901 in a protruding manner, a positioning hole 201 is formed in the center of the conductive film 200, the positioning protrusion 910 is inserted into the positioning hole 201, and the conductive film 200 is limited but can be rotatably disposed through the matching of the positioning hole 201 and the positioning protrusion 910.

In order to realize that the conductive film 200 is pushed by the passing water body to rotate, in one embodiment, a plurality of protrusions 210 are arranged on the conductive film 200 at intervals, and a groove 220 is formed between adjacent protrusions 210. Specifically, in the conductive film 200, a plurality of projections 210 are provided at intervals in the circumferential direction on the thickness end face, and a groove 220 is formed between adjacent projections 210. When water flows, the protrusions 210 of the conductive film 200 are pushed to move so that the conductive film 200 integrally rotates, for example, as shown in fig. 2, the conductive film 200 is in a gear shape, as shown in fig. 3, the conductive film 200 is in a polygonal star shape, and as shown in fig. 210, the protrusions 210 are in a regular or irregular blade shape, which is not always redundant in this embodiment.

In order to improve the washing effect, in one embodiment, as shown in fig. 2 and 3, the number of the conductive films 200 is multiple, and the conductive films 200 are spaced apart from each other on the same plane in the plate space 700. Through the setting that sets up a plurality of conducting films 200, drive the water in the rotation, the washing effect is better.

In one embodiment, the end surface of the conductive film 200 facing the first electrode 100 is at least partially exposed to the water flow channel. Because the end face of the conductive film 200 facing the first electrode 100 is exposed in the water flow channel, a water body can infiltrate the end face when passing through the water flow channel, so that the water receiving area of the conductive film 200 is increased, the electrolysis efficiency is improved, and the concentration of electrolyzed water is increased.

In order to make the description more concise and clearer, an end surface of the conductive film 200 facing the first electrode 100 is defined as a first end surface 202 in the following description, and the first end surface 202 mentioned below is an end surface of the conductive film 200 facing the first electrode 100.

In order to realize that the end surface of the conductive film 200 facing the first electrode 100 is at least partially exposed to the water flow channel, in embodiment 2, as shown in fig. 4, the conductive film 200 is disposed in the plate space 700, and the conductive film 200 is spaced apart from the first electrode 100, that is, the first end surface 202 is spaced apart from the first electrode 100, for example, the height of the plate space 700 (precisely, the vertical distance between the first electrode 100 and the second electrode 300 which are disposed in parallel, that is, the polar distance) is set to be greater than the thickness of the conductive film 200, so that the first end surface 202 can be exposed to the water flow channel and thereby be soaked by the water. Importantly, by separating the first end face 202 from the first electrode 100, a body of water can be circulated in the gap between the first end face 202 and the first electrode 100, more effectively scouring the first electrode 100.

In order to separate the conductive film 200 from the first electrode 100, for example, a positioning protrusion 910 is formed on the side wall of the electrolytic chamber 901 in a protruding manner, a positioning hole 201 is formed in the center of the conductive film 200, the positioning protrusion 910 is inserted into the positioning hole 201, by matching the positioning holes 201 and the positioning protrusions 910, the conductive film 200 is limited but can be rotatably arranged at the same time, a step portion 911 is provided on the positioning protrusion portion 910, the conductive film 200 is attached to the second electrode 300 through the step portion 911, one surface of the first electrode 100 facing the conductive film 200 is abutted against the step portion 911, specifically, the first electrode 100 is provided with an electrode positioning hole 102, the electrode positioning hole 102 penetrates through the positioning protrusion 910, and one surface of the first electrode 100 facing the conductive film 200 abuts against the step portion 911, so that the conductive film 200 and the first electrode 100 are spaced apart from each other.

Furthermore, as shown in fig. 4 and 5, a positioning protrusion 910 is formed on a side wall of the electrolytic chamber 901 in a protruding manner, the first electrode 300 is provided with a second positioning hole 302, and the positioning protrusion 910 is inserted into the second positioning hole 302 and passes through the positioning hole 201 of the conductive film and the electrode positioning hole 102 of the first electrode 100, so that the first electrode 100 abuts against the step portion 911 and is separated from the conductive film 200.

Alternatively, in order to realize that at least a portion of the end surface of the conductive film 200 facing the first electrode 100 is exposed to the water flow channel, embodiment 3 is provided, in which the conductive film 200 is attached to the first electrode 100, a water channel is opened on a surface of the first electrode 100 facing the first end surface 202, the water channel is opened opposite to the conductive film 200, the first electrode 100 is separated from the first end surface 202 on the portion where the water channel is opened, so that the first end surface 202 is exposed to the water flow channel, and the water body flows to the water channel and infiltrates the first end surface 202 of the conductive film 200.

For another example, in order to realize that the end surface of the conductive film 200 facing the first electrode 100 is at least partially exposed to the water flow channel, embodiment 4 is proposed, in which the conductive film 200 is attached to the first electrode 100, a first electrode chamber 109 is formed between the first electrode 100 and the side wall of the electrolytic chamber 901, the first electrode 100 is provided with a plurality of first through holes 101, the first through holes 101 are disposed opposite to the conductive film 200 so that the first end surface 202 is at least partially exposed to the water flow channel, and the plate space 700 is communicated with the first electrode chamber 109. For example, the water inlet 902 is connected to the first electrode chamber 109, so that the water can flow into the first electrode chamber 109, and then the water infiltrates the first end surface 202 through the first through hole 101.

As a preferred embodiment, the present invention further provides embodiment 5, referring to fig. 4 again, the conductive film 200 is disposed in the plate space 700, the conductive film 200 is disposed apart from the first electrode 100 at an interval, a first electrode chamber 109 is formed between the first electrode 100 and the sidewall of the electrolytic cavity 901, the first electrode 100 is provided with a plurality of first through holes 101, and the first through holes 101 are disposed opposite to the conductive film 200, so that the first end surface 202 is at least partially exposed to the water flow channel. The water body flows through the gap between the first end face 202 and the first electrode 100, the surface of the first electrode 100 is washed, the conductive film 200 is soaked, the electrolysis efficiency is improved, the water body can flow through the first through hole 101 in the first electrode chamber 109 and the polar plate space 700, and the water body flow rate is increased.

In the above embodiments 3, 4 and 5, the first electrode compartment 109 and the plate space 700 together constitute a part or the whole of the water flow passage.

In example 6, a first electrode chamber 109 is formed between the first electrode 100 and the side wall of the electrolytic chamber 901, the first electrode 100 is provided with a plurality of first through holes 101, so that the plate space 700 communicates with the first electrode chamber 109, and water flow can flow between the first electrode chamber 109 and the plate space 700. Further, for example, the size of the water inlet 902 is larger than the size of the water outlet 903, such that the pressure of the water flow at the water outlet is increased, thereby increasing the solubility of products (e.g., ozone) in the electrolyzed water, such that the solubility of ozone bubbles is increased, thereby increasing the concentration of the electrolyzed water. In a specific embodiment, as shown in fig. 4, the water flow direction is as shown by the arrow on the figure, the water inlet 902 is communicated with the first electrode chamber 109 and the polar plate space 700, and the water outlet 903 is communicated with the polar plate space 700 only, so that the water flow at the water inlet 903 is large, the water flow at the water outlet 903 is smaller than the water flow introduced at the water inlet 902, the water pressure at the water outlet 903 is increased, the solubility of the electrolyzed water product (e.g., ozone) is improved, and the solubility of ozone bubbles is increased, and, as shown in fig. 4, because the first electrode chamber 109 is not communicated with the water outlet 903, the water introduced to the first electrode chamber 109 flows forward and collides with the side wall, the water body rotates, and the dissolution of the gas can be accelerated during the collision and rotation of the water body, so as to increase the concentration of the electrolyzed water.

Therefore, the water body can be ensured to flow out of the water outlet 903 through electrolysis, and the concentration of the electrolyzed water is improved.

The rotating speed of the conductive film 200 is related to the flow rate of the introduced water and the water pressure, the flow rate of the water is increased under the condition of high water pressure, the rotating speed of the conductive film is increased, and the rotating speed of the conductive film can be controlled by controlling the water pressure, so that the scouring force can be adjusted.

In embodiments 2 and 5, the conductive film 200 is separated from the first electrode 100, that is, the end face (the first end face 202) of the conductive film 200 facing the first electrode 100 is separated from the first electrode 100, and embodiments 3 and 4 provide a structure in which the conductive film 200 is attached to the first electrode 100, and in both structures, the conductive film 200 can wash the first electrode 100 and itself by rotation, thereby preventing scale from accumulating. Therefore, in order to avoid the significant increase of the electrolytic power consumption caused by the excessive inter-electrode distance impedance, the present invention defines the distance between the conductive film 200 and the first electrode 100, and in one embodiment, the distance between the conductive film and the first electrode is 0 to 0.5MM, it is understood that the distance between the conductive film and the first electrode is a perpendicular distance between the end surface (first end surface) of the conductive film facing the first electrode and the end surface of the first electrode facing the conductive film, and preferably, the distance between the conductive film and the first electrode is 0 to 0.2 MM. In the above range, the conductive film can be surely washed out well to the first electrode and itself, and in this range, the inter-electrode distance resistance is small.

As a preferable aspect of the present invention, for example, as shown in fig. 5, a second electrode chamber 309 is formed between the first electrode 300 and the side wall of the electrolytic chamber 901, and the second electrode 300 is provided with a plurality of second through holes 301 so that the plate space 700 and the second electrode chamber 309 communicate with each other, and water flow can flow between the second electrode chamber 309 and the plate space 700. Further, for example, the second through-hole 301 is at least partially displaced from the projection of the conductive film 200 in the direction of the membrane electrode overlap, that is, the second through-hole 301 is partially displaced from or completely displaced from the projection of the conductive film 200 in the direction of the membrane electrode overlap. For example, in order to increase the water flow rate, the second through-hole 301 and the conductive film 200 are completely displaced in the overlapping direction of the membrane electrode, so that the electrolytic water can be quickly transferred into the second electrode chamber 309 and carried out. On the other hand, since the portion of the surface of the second electrode 300 to which the conductive film 200 is attached has a small working surface, the second through-hole 301 having a projection offset from the conductive film 200 is opened, so that the working area (the side wall of the through-hole is the working surface) can be increased, and the concentration of the electrolyzed water can be increased. The water outlet 903 may be in communication with the second electrode chamber 309, and the electrolyzed water flows out from the second electrode chamber 309 to the water outlet 903.

Wherein the product of the electrolyzed water can be ozone, hypochlorite, hydroxyl radical, oxygen atom, oxygen molecule, etc., which are not described in detail.

For example, the first electrode 100 is a cathode, the material of the first electrode 100 may be platinum, stainless steel, titanium, or the like, the second electrode 300 is an anode, and the material of the second electrode 300 may be one of conductive silicon, conductive diamond, titanium, platinum, lead oxide, and tantalum oxide, or another material having conductivity. For example, the conductive membrane 200 is an ion exchange membrane, and more specifically, the conductive membrane is a proton exchange membrane.

An electrolytic water device comprises a water inlet pipe and a plurality of electrolytic water assemblies of any one of the above items, wherein a pipe cavity of the water inlet pipe is communicated with the water inlet of each electrolytic water assembly. Through setting up a plurality of electrolysis water subassembly and inlet tube intercommunication, improve the concentration of electrolysis water.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
