DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0028] like Figures 1 to 5 As shown, the cathode module of the utility model comprises:

[0029] An electrolytic box 1, wherein a cathode chamber 11 is provided in the electrolytic box 1, and an opening is provided on one side of the cathode chamber 11, and a vibrating sheet 4 for sealing the opening is connected to the opening;

[0030] A cathode member 2, wherein the cathode member 2 is disposed in the cathode chamber 11;

[0031] A connecting member 3, wherein the connecting member 3 is arranged in the cathode cavity 11, one end of the connecting member 3 is fixed to the vibration plate 4, and the other end of the connecting member 3 is fixed to the cathode member 2;

[0032] The vibration generating device 5 is connected to the outside of the vibration plate 4 to drive the vibration plate 4 to vibrate. The vibration generating device 5 drives the vibration plate 4 to vibrate, and the vibration plate 4 drives the cathode part 2 to vibrate through the connecting member 3. The vibration of the cathode part 2 can prevent the calcium ions, magnesium ions, etc. in the water from reacting with the hydroxide ions produced by the cathode part 2 to generate scale, reduce the amount of scale deposited on the surface of the cathode part 2, and can clean the scale deposited on the surface of the cathode part 2. In addition, during the electrolysis process, a large number of bubbles will be generated on the surface of the cathode part 2. The bubbles adhere to the surface of the cathode part 2, which will cause the effective area of ​​the electrode to decrease, increase the electrolysis resistance, increase the energy consumption, and thus reduce the efficiency. The generation of scale will lead to a decrease in the output of electrolyzed water and an increase in energy consumption, and the generation of bubbles will increase the energy consumption of the electrolysis device. The connecting member 3 drives the cathode part 2 to vibrate, which can not only prevent scale from being deposited on the surface of the cathode part 2, but also the cathode part 2 is always in vibration, and the bubbles generated during the electrolysis process are not easy to adhere to the surface of the cathode part 2, thereby effectively protecting the cathode reaction area. Therefore, the utility model can eliminate scale on the surface of the cathode component 2 and accelerate the desorption of bubbles on the surface of the cathode component 2, thereby reducing the resistance of the electrolytic cell, reducing energy consumption, and improving electrolysis efficiency.

[0033] Further, the connecting member 3 is a rod, the vibration sheet 4 is an elastic sheet, one end of the rod is connected to the middle of the cathode member 2, and the other end of the rod is sealed through the vibration sheet 4 and fixed to the vibration generating device 5. Specifically, the vibration generating device 5 drives the connecting member 3 to vibrate while driving the vibration sheet 4 to vibrate. The vibration of the vibration sheet 4 can drive the electrolyte in the cathode chamber 11 to oscillate back and forth. The oscillation of the electrolyte can increase the solubility of the electrolyte for the precipitate, thereby reducing the precipitation amount of the precipitate in the electrolyte, and further increasing the electrolyte amount and electrolysis efficiency.

[0034] Specifically, when ultrasonic waves propagate in water, the mechanical action of the sound waves will affect the dissolved salts and suspended particles in the water, which will have a certain inhibitory effect on the scaling process, as follows:

[0035] Dispersion: Ultrasonic mechanical vibration can disperse particulate matter in water, including mineral particles that may form scale. This dispersion effect can prevent these particulate matter from depositing on the container wall or equipment surface, thereby reducing the possibility of scaling.

[0036] Cavitation effect: When ultrasound propagates in water, it produces the so-called "cavitation phenomenon". This means that under the action of ultrasound, tiny bubbles in the water grow and collapse rapidly, generating high-intensity local shock waves. These shock waves help to destroy scale layers and microbial membranes, making it difficult for them to form new scale layers on the surface of the equipment.

[0037] Improve solubility: The vibration effect of ultrasound may help to increase the solubility of certain salts in water, so that these substances exist in the water in a dissolved state instead of being deposited to form scale.

[0038] Cleaning effect: Ultrasonic waves can clean the scale layer that has already formed and peel it off the surface of the equipment, thereby maintaining the cleanliness of the equipment surface and reducing the formation of new scale.

[0039] Inhibit crystal growth: Ultrasonic vibration may interfere with the growth process of scale crystals, making it difficult for the crystals to arrange in a normal manner, thereby inhibiting the formation of scale.

[0040] In this embodiment, the connector 3 is a conductor, and one end of the connector 3 close to the vibration plate 4 extends out of the vibration plate 4 and is electrically connected to a power source. Specifically, the connector 3 not only drives the cathode member 2 to vibrate, but also acts as a conductor, making the cathode module structure of the utility model more concise and compact.

[0041] In this embodiment, the vibration generating device 5 is an ultrasonic generator; in other embodiments of the present invention, the vibration generating device 5 may be a vibrator.

[0042] To ensure the silent effect of the cathode module, in this embodiment, the outer cover of the vibration generating device 5 is provided with a soundproof cover 6. Specifically, the soundproof cover 6 is provided on the outer side of the vibration generating device 5, and is detachably connected to the outside of the side of the box body where the vibration generating device 5 is installed through fasteners.

[0043] To facilitate the cleaning of the accumulated sediment in the cathode chamber 11 , in this embodiment, a sewage outlet 111 is provided at the bottom of the cathode chamber 11 , and an exhaust hole is provided at the top of the cathode chamber 11 , and the exhaust hole is used to discharge the hydrogen generated by electrolysis of water out of the cathode chamber 11 .

[0044] An embodiment of an electrolysis device includes the above-mentioned cathode module, and the electrolysis device also includes an electrolytic diaphragm 8 and an anode component 7. The electrolytic diaphragm 8 is fixed in the middle of the inner cavity of the electrolysis box 1. The electrolytic diaphragm 8 divides the inner cavity of the electrolysis box 1 into a cathode cavity 11 and an anode cavity 12. The anode component 7 is arranged in the anode cavity 12.

[0045] Among them, a water inlet 121 is provided at the bottom of the anode chamber 12, and a water outlet 122 is provided at the top of the anode chamber 12. The water inlet is set at the bottom of the anode chamber 12, and the fresh water entering the anode chamber 12 needs to overcome its own gravity under the action of water pressure and pass through the flow channel from bottom to top. By controlling the magnitude of the water pressure, the flow speed of the water flow from bottom to top can be flexibly adjusted. In this embodiment, the water inlet 121 is set at the lower end of the anode chamber 12, which can make the flow speed of the water flow slower than that of the water inlet 121 set at the upper part of the anode chamber 12, so that the contact time between the water flow and the anode member 7 is longer, which is conducive to the full progress of the reaction.

[0046] Furthermore, a plurality of partitions 9 are fixed in sequence from top to bottom in the anode chamber 12, and at least one side of each partition 9 is spaced apart from the chamber wall of the anode chamber 12. Each partition 9 can block the water flow from bottom to top, further reduce the flow velocity of the water flow, and thus further increase the flow velocity of the water flow flowing in from the water inlet 121.

[0047] In this embodiment, in order to facilitate fixing of the anode member 7 , the electrolysis device includes a conductive rod 10 which is sealed and penetrates through the cavity wall of the anode cavity 12 , and one end of the conductive rod 10 located in the anode cavity 12 is fixedly connected to the anode member 7 .

[0048] Specifically, in this embodiment, the anode member 7 and the cathode member 2 are both mesh flat plates, the circumference of the anode member 7 is spaced apart from the cavity wall of the anode cavity 12, the circumference of the cathode member 2 is spaced apart from the cavity wall of the cathode cavity 11, and the anode member 7 and the cathode member 2 are respectively fixed to one side of the box body by the conductive rod 10 and the connector 3. In other embodiments of the utility model, one end of the cathode member 2 can be connected to the cavity wall of the cathode cavity 11, and one end of the anode member 7 can be connected to the cavity wall of the anode cavity 12.

[0049] In summary, the electrolysis device of the utility model comprises an electrolysis box 1, a cathode component 2, a connector 3 and a vibration generating device 5. A cathode cavity 11 is provided in the electrolysis box 1. An opening is provided on one side of the cathode cavity 11. A vibration plate 4 for blocking the opening is connected to the opening. The cathode component 2 and the connector 3 are both arranged in the cathode cavity 11. One end of the connector 3 fixes the vibration plate 4, and the other end of the connector 3 fixes the cathode component 2. The vibration generating device 5 is connected to the outside of the vibration plate 4. The vibration generating device 5 drives the vibration plate 4 to vibrate. The vibration plate 4 drives the cathode component 2 to vibrate through the connector 3. The vibration of the cathode component 2 can prevent calcium ions, magnesium ions, etc. in water from reacting with hydroxide ions produced by the cathode component 2 to generate scale, reduce the amount of scale deposited on the surface of the cathode component 2, and can clean the scale deposited on the surface of the cathode component 2.
