Description

Technical Field

[0001] The invention belongs to the technical field of water purification, and in particular relates to a water purification device with a sterilization function. Background Art

[0002] Nowadays, water pollution poses a serious threat to human health and the environment. In order to ensure the safety and hygiene of drinking water, many water purification equipment have come into being.

[0003] At present, water purification equipment filters drinking water through multi-layer filtration to achieve the function of sterilizing and purifying water. For example, the patent publication number is: CN108623036A, a water purification equipment with sterilization function. The existing patent has the following shortcomings:

[0004] First, the existing water purification equipment uses an activated carbon layer to filter the sterilized water to remove chlorine and then remove the odor in the water. The activated carbon can adsorb some combustibles in the process of filtering water, such as organic solvents, volatile organic compounds, oils, etc. These combustibles attached to the activated carbon are easy to react with chlorine in an exothermic reaction, and the heat of reaction is high enough to cause the internal heat of the water purification equipment. If the heat cannot be effectively handled, it may cause damage to the water purification equipment.

[0005] Second, after the existing water purification equipment sterilizes the water, the pH of the water is difficult to control, and a neutralizer needs to be added to neutralize the pH of the water. However, when the neutralizer is mixed with water, it is difficult to control the amount of the agent added. Adding too much will be harmful to human health. The intake of overly acidic or alkaline water may interfere with the body's water and electrolyte balance, which may have a negative impact on health.

[0015] Compared with the existing technology, the advantages of the water purification device with sterilization function in the present invention are:

[0018] 3. Through the ion selective membrane and driving mechanism, the ion selective electrode plate can adsorb high-concentration ions and pollutants in the water. The high-concentration ions are adsorbed to the surface of the ion selective membrane, which is a sensitive membrane that selectively interacts with the ions of interest. It can effectively remove heavy metal ions, organic matter and other toxic substances in the water, and provide safer drinking water. When too many impurities are adsorbed to the surface of the glass cover, ultraviolet light will be hindered, so that the resistance of the reverse photoresistor becomes smaller, which can automatically prompt the user to replace the filter and automatically raise the filter to facilitate the user to replace it, greatly improving the practicality of the device.

[0019] 4. Through the sterilization mechanism set up, certain ions or pollutants with high concentrations in the water can be adsorbed through the ion-selective electrode plate, and ultraviolet radiation can be used to sterilize bacteria, viruses and other microorganisms in the water. The device uses a high-energy ultraviolet light source and has a strong sterilization effect. Through the set filtering mechanism, a layer of activated carbon adsorption layer is added to remove residual chlorine and odor in the water. The combination of ultraviolet sterilization technology and activated carbon adsorption technology can not only effectively sterilize, but also remove residual chlorine and odor, providing safer and purer drinking water, which can not only improve the taste of water, but also reduce the content of harmful substances in water.

[0035] The operating principle of the present invention is described as follows: when in use, the water to be purified is first introduced into the interior of the water purification tank body 1 through the water inlet 12, and at the same time, the two ion selective electrode plates 203 can adsorb high-concentration ions and pollutants in the water. The high-concentration ions are adsorbed onto the surface of the ion selective membrane 206, which is a sensitive film that selectively interacts with the ions of interest. At the same time, the ultraviolet lamp 207 in the glass cover 205 on one side sterilizes and disinfects the water, and the reverse photoresistor 208 on the other side can receive the light emitted by the ultraviolet lamp 207. When the pollutants and ions on the surface of the ion selective membrane 206 are absorbed too much, the light emitted by the ultraviolet lamp 207 will be hindered to a certain extent. At this time, the resistance value of the reverse photoresistor 208 becomes smaller, and the electric The flow becomes larger, causing the warning light to stay on, and then the pressurizer 702 can be started, and the pressurizer 702 is used to continuously pressurize the L-shaped tube 701, the liquid level on the right side drops, and the liquid level on the left side rises, pushing the sealing piston 708 upward, and then using the push rod 709 and the push plate 710 to push the filter body 204 upward, thereby driving the ion selective electrode plate 203 on the upper end of the filter body 204 to move upward, and then open the control valve 707 on the exhaust pipe 706 to discharge the air inside. According to the principle of communicating vessels, the liquid levels on both sides of the L-shaped tube 701 are level, the push plate 710 returns to its position, and then the new filter body 204 can be installed, so that the user can be automatically prompted to replace the filter body 204, and the filter body 204 is automatically raised to facilitate the user to replace, thereby greatly improving the practicality of the device.

[0036] After the ultraviolet lamp 207 sterilizes, the water is introduced into the guide tube 4 through the filter body 204, and the falling water can be guided to the mixing chamber 8 for secondary treatment. After the water enters the mixing chamber 8, the color sensor 14 is electrically connected to the external power supply. The color sensor 14 controls the one-way electromagnetic valve 22 on the medicine box 9 by sensing the color change on the pH test paper 13, and can control the amount of medicine according to the pH value of the water, so as to better sterilize and disinfect the water. Then, the rotating motor 801 is started to drive the rotating rod 802 and the stirring rod 803 to rotate, so that the water and the medicine can be fully mixed under the rotation of the stirring rod 803 to achieve a better purification effect. Then, the drain port 601 is opened to facilitate the outflow of purified water. Then, by setting the filtering mechanism 6, the sterilized water is finely filtered through the filtering mechanism 6 to remove impurities, thereby improving the purity of the water and making drinking water safer and more reliable. , combining ultraviolet sterilization technology and activated carbon adsorption technology, it can not only effectively sterilize, but also remove residual chlorine and odor, providing safer and purer drinking water, which can not only improve the taste of water, but also reduce the content of harmful substances in water. After fine filtration through the activated carbon layer 603, the water mixed with the agent will still have chlorine. When chlorine reacts with organic matter adsorbed on the activated carbon, it will release heat, so that the internal temperature of the entire water purification equipment will increase, affecting the use of parts inside the water purification tank body 1. When heat is released after the reaction, the airbag 18 expands due to the heat, causing the touch rod 19 to touch the press switch 17. The press switch 17 is electrically connected to the condensation plate 20. The condensation plate 20 controls the temperature of the water in the water storage chamber 15, and releases hot air through the heat release hole 21 at the lower end of the condensation plate 20, thereby extending the service life of the water purification equipment, effectively sterilizing, and removing residual chlorine and odor, providing safer and purer drinking water.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

The pressurizer (702) is started and used to continuously apply pressure to the L-shaped tube (701). The liquid level on the right side decreases and the liquid level on the left side increases, pushing the sealing piston (708) upward. The push rod (709) and the push plate (710) are then used to push the filter body (204) upward, thereby driving the ion selective electrode plate (203) at the upper end of the filter body (204) to move upward. The control valve (707) on the exhaust pipe (706) is then opened to discharge the air inside. According to the principle of communicating vessels, the liquid levels on both sides of the L-shaped tube (701) are level, the push plate (710) returns to its original position, and then a new filter body (204) can be installed. This automatically prompts the user to replace the filter body (204) and automatically raises the filter body (204).
