Description

Technical Field

[0001] This invention relates to the field of drinking water preparation technology, specifically to a drinking water preparation apparatus. Background Technology

[0002] Hydrogen-rich water refers to functional drinking water containing a high concentration of molecular hydrogen. Its preparation technology is mainly based on the physical dissolution or chemical reaction principles of hydrogen. Currently, the mainstream preparation methods include three main processes: electrolysis, high-pressure dissolution, and metal reduction. Electrolysis uses a proton exchange membrane electrolyzer to electrolyze pure water, generating high-purity hydrogen gas at the cathode side. This hydrogen gas is then stably dissolved in the water using micro-nano bubble technology. High-pressure dissolution uses food-grade hydrogen cylinders and a specially designed dissolution device to dissolve hydrogen gas in water at a pressure of 0.3-0.5 MPa. A vortex mixing process can further improve dissolution efficiency. The metal reduction method mainly utilizes magnesium rods or particles to react with water to generate hydrogen gas. While simple to operate, it carries the risk of metal ion contamination. Studies have shown that the molecular hydrogen in hydrogen-rich water has selective antioxidant properties, effectively scavenging harmful reactive oxygen species such as hydroxyl radicals, demonstrating potential application value in improving metabolic syndrome and delaying aging.

[0003] According to Chinese Patent Publication No. CN120097494A, a hydrogen-rich water preparation device and method are disclosed. This invention relates to the field of hydrogen-rich water preparation technology, including a preparation tank and a base fixedly connected to the lower surface of the preparation tank; a water inlet mechanism for injecting water into the inner cavity of the preparation tank. By setting the water inlet mechanism, drinking water filtered and purified by a water dispenser can be injected into the inner cavity of the preparation tank. During the water flow, hydrogen gas floating at the top of the preparation tank can be brought back to the bottom of the preparation tank, thereby accelerating the dissolution rate of hydrogen gas during the water injection process; and a stirring mechanism for discharging hydrogen gas into the water flow during the stirring process. By setting the stirring mechanism, the drinking water in the inner cavity of the preparation tank can be stirred during operation, and the centrifugal force is used to achieve the effect of fully dissolving hydrogen gas in the water.

[0004] When the above-mentioned device is in use, although hydrogen is injected into drinking water and dissolved and mixed by stirring, since hydrogen is a gas, some hydrogen cannot dissolve in the water in a short time. At this time, the hydrogen that has not dissolved in the water will float to the surface and drift into the upper chamber of the device, resulting in the problem that some hydrogen cannot dissolve and mix with water. Therefore, a drinking water preparation device is proposed to solve the above-mentioned problem. Summary of the Invention

[0013] Preferably, the air cylinder is fixedly installed on the inner top wall of the housing, a one-way air inlet valve is fixedly installed on the air inlet of the air cylinder, a one-way air outlet valve is fixedly installed on the air outlet of the air cylinder, an air supply pipe is fixedly installed on the one-way air outlet valve, and a second nozzle is fixedly installed at the other end of the air supply pipe.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This drinking water preparation device involves injecting drinking water into the tank, submerging the mounting frame, and connecting a hydrogen delivery device to the outside of the tank to fill the drinking water with hydrogen. The drive motor is then activated to rotate the stirring shaft, causing the stirring blades to agitate the drinking water and promote the mixing of hydrogen and water. During the rotation of the stirring shaft, the connecting rod pushes the reciprocating rod up and down, allowing the lifting rod to move up and down. When the first piston rod inside the first water cylinder moves upward, it draws drinking water into the first water cylinder. When the first piston rod moves downward, it sprays the drawn drinking water through a one-way atomizing nozzle into the upper chamber of the tank, where it comes into contact with the hydrogen in the upper chamber, improving the utilization rate and mixing efficiency of the hydrogen.

[0015] 2. In this drinking water preparation device, the lifting rod moves up and down, which in turn drives the second piston rod to move up and down. When the second piston rod moves upward, drinking water enters the interior of the second water cylinder. Under the action of centrifugal force, the spiral blades promote the mixing and dissolution of the drinking water with the hydrogen bubbles in the water. As the second piston rod rises, its shaft rotates under the action of the fixed column and the spiral slide, allowing the blades to further stir the drinking water and improve the dissolution efficiency of drinking water and hydrogen. When the second piston rod descends, the drinking water in the second water cylinder is sprayed out by a manual one-way nozzle. The water jet sprayed from the one-way nozzle impacts the impact plate, allowing the hydrogen bubbles in the water jet to further dissolve with the water. The guide groove is designed to guide the impacted water jet, allowing the water to splash in all directions and come into contact with the hydrogen in the upper chamber of the tank, thereby improving the dissolution efficiency of hydrogen and water.

[0016] 3. This drinking water preparation device, during the up-and-down movement of the lifting rod, drives the third piston rod to move up and down, allowing hydrogen gas in the upper chamber of the tank to enter the gas cylinder, and then enter the gas delivery pipe through the one-way gas outlet valve, and finally be injected into the drinking water through the second nozzle. It can draw in the hydrogen gas floating on the surface of the water in the upper chamber of the tank and inject it into the drinking water in the tank, realizing the circulation of hydrogen gas into the water and improving the utilization rate of hydrogen gas.

[0017] 4. This drinking water preparation device, by starting the drive motor to drive the stirring shaft to rotate, can drive the atomizing mechanism, auxiliary mechanism and circulation mechanism to operate, realize the atomization, centrifugation, and impact of drinking water and the circulation and utilization of hydrogen, which can improve the efficiency of mixing drinking water and hydrogen and the utilization rate of hydrogen, thus improving the practicality of the drinking water preparation device.

The atomizing mechanism 2 includes a connecting rod 201 and a guide seat 202. A reciprocating rod 203 is slidably connected inside the guide seat 202. The lower end of the reciprocating rod 203 is hinged to the connecting rod 201 by a pin. A lifting rod 204 is fixedly installed on the upper end of the reciprocating rod 203. A first water cylinder 205 is arranged below the lifting rod 204. A first piston rod 206 is movably connected inside the first water cylinder 205. The upper end of the first piston rod 206 is fixedly installed on the lifting rod 204. A delivery pipe 207 is fixedly installed on the first water cylinder 205. A one-way atomizing nozzle 208 is fixedly installed on the delivery pipe 207. A first one-way valve 209 is fixedly installed at the lower end of the first water cylinder 205. By injecting drinking water into the housing 1, the drinking water submerges the mounting frame 13, and... The connecting pipe 9 is connected to an external hydrogen delivery device to fill the drinking water inside the tank 1 with hydrogen. The drive motor 5 is started to drive the stirring shaft 6 to rotate, so that the stirring blade 12 stirs the drinking water and promotes the dissolution of hydrogen and water. During the rotation of the stirring shaft 6, the connecting rod 201 will drive the reciprocating rod 203 to move up and down, so that the lifting rod 204 can move up and down. When the first piston rod 206 inside the first water cylinder 205 is driven upward by the lifting rod 204, the drinking water can be drawn into the first water cylinder 205. When the first piston rod 206 moves downward, the drawn drinking water can be sprayed into the upper chamber of the tank 1 through the one-way atomizing nozzle 208, so that it can come into contact with the hydrogen in the upper chamber, thereby improving the utilization rate and dissolution efficiency of hydrogen. The auxiliary mechanism 3 includes a second water cylinder 301 and a second piston rod 302. The second piston rod 302 is movably connected inside the second water cylinder 301. A spiral blade 303 is fixedly installed inside the second water cylinder 301. A receiving groove 306 is provided inside the second piston rod 302. A fixing column 313 is fixedly installed inside the receiving groove 306. A rotating shaft 305 is provided inside the second water cylinder 301. A spiral groove 314 is provided on the rotating shaft 305. The fixing column 313 is slidably connected inside the spiral groove 314. A blade 307 is fixedly installed at the lower end of the rotating shaft 305. A one-way nozzle 308 is fixedly installed on the second water cylinder 301. A fixing plate 310 is fixedly installed on the second water cylinder 301. An impact plate 311 is fixedly installed at the bottom of the fixing plate 310. When the lifting rod 204 moves up and down, it will drive the second piston rod 302 to move up and down. When the second piston rod 302 moves upward, drinking water enters the interior of the second water cylinder 301. Under the action of centrifugal force, the spiral blades 303 promote the mixing and dissolution of the drinking water with the hydrogen bubbles in the water. As the second piston rod 302 rises, its rotating shaft 305 rotates under the action of the fixed column 313 and the spiral slide 314, allowing its blades 307 to further stir the drinking water and improve the dissolution efficiency of drinking water and hydrogen. When the second piston rod 302 descends, the drinking water in the second water cylinder 301 is sprayed out by the artificial one-way nozzle 308. The water column sprayed by the one-way nozzle 308 hits the impact plate 311, allowing the hydrogen bubbles and water in the water column to further dissolve. The guide groove 312 guides the water column after the impact, allowing the water to splash in all directions and come into contact with the hydrogen in the upper chamber of the tank 1, improving the dissolution efficiency of hydrogen and water.

[0023] The connecting rod 201 is rotatably connected to the stirring shaft 6 via a bearing. The guide seat 202 is fixedly installed on the inner wall of the housing 1. The first water cylinder 205 is fixedly installed on the mounting bracket 13. The lower end of the first one-way valve 209 is fixedly installed with a water suction cover 210. The setting of the first one-way valve 209 can prevent the water pumped into the first water cylinder 205 from flowing back. The setting of the mounting bracket 13 can support and fix the first water cylinder 205.

[0024] The second piston rod 302 is fixedly installed on the lifting rod 204. The lower end of the second water cylinder 301 is fixedly installed with a second one-way valve 309. The inside of the second water cylinder 301 is fixedly installed with a fixing frame 304. The rotating shaft 305 is rotatably connected to the inside of the fixing frame 304 through a bearing. The setting of the second one-way valve 309 can prevent the water drawn into the second water cylinder 301 from flowing back. The fixing frame 304 can support the rotating shaft 305, making the rotating shaft 305 more stable when rotating.

[0025] The impact plate 311 is located directly above the one-way nozzle 308. A guide groove 312 is provided at the bottom of the impact plate 311. The second water cylinder 301 is fixedly installed on the mounting bracket 13. The impact plate 311 allows the water column sprayed from the one-way nozzle 308 to impact the impact plate 311, allowing the hydrogen bubbles and water in the water column to further mix. The guide groove 312 guides the water column after impact, allowing the water to splash in all directions and come into contact with the hydrogen in the upper chamber of the housing 1, thereby improving the mixing efficiency of hydrogen and water.

[0026] A first nozzle 8 is fixedly installed on the gas pipe 7, and a connecting pipe 9 is fixedly installed at the bottom of the gas pipe 7. A drain outlet 10 is opened inside the box body 1. Hydrogen delivery equipment can be connected to the external hydrogen delivery equipment through the connecting pipe 9, and hydrogen can be injected into the drinking water in the box body 1 through the first nozzle 8 on the gas pipe 7.

[0027] A water inlet 11 is provided on the side wall of the housing 1. The stirring shaft 6 is rotatably connected to the inside of the housing 1 through a bearing. The stirring blade 12 is fixedly installed on the stirring shaft 6. The stirring shaft 6 can be rotated by starting the drive motor 5, so that the stirring blade 12 mixes and stirs the water and hydrogen inside the housing 1.

[0028] Working principle: Drinking water is injected into the tank 1, submerging the mounting frame 13. Hydrogen is then introduced into the tank 1 via a hydrogen delivery device connected to the connecting pipe 9. The drive motor 5 is activated, rotating the stirring shaft 6, which in turn stirs the drinking water with the stirring blades 12, promoting the mixing of hydrogen and water. During the rotation of the stirring shaft 6, the connecting rod 201 pushes the reciprocating rod 203 up and down, allowing the lifting rod 204 to move up and down. When the first piston rod 206 inside the first water cylinder 205 moves upwards, it draws drinking water into the first water cylinder 205. When the first piston rod 206 moves downwards, it sprays the drawn drinking water through the one-way atomizing nozzle 208 into the upper chamber of the tank 1, where it comes into contact with the hydrogen, improving hydrogen utilization and mixing efficiency. The up-and-down movement of the lifting rod 204 also drives the reciprocating rod 203 to move the connecting rod 201 up and down, promoting the mixing of hydrogen and water. The second piston rod 302 moves up and down. When the second piston rod 302 moves upward, drinking water enters the interior of the second water cylinder 301. Under the action of centrifugal force, the spiral blades 303 promote the mixing and dissolution of the drinking water with the hydrogen bubbles in the water. As the second piston rod 302 rises, its rotating shaft 305 rotates under the action of the fixed column 313 and the spiral slide 314, so that the blades 307 can further stir the drinking water and improve the dissolution efficiency of drinking water and hydrogen. When the second piston rod 302 falls, the drinking water in the second water cylinder 301 is sprayed out by the artificial one-way nozzle 308. The water column sprayed by the one-way nozzle 308 hits the impact plate 311, so that the hydrogen bubbles and water in the water column can be further dissolved. The guide groove 312 can guide the water column after the impact, so that the water can splash in all directions and come into contact with the hydrogen in the upper chamber of the tank 1, improving the dissolution efficiency of hydrogen and water.

[0029] Please see Figure 1-10 Based on the above embodiments, in another embodiment of the present invention, a circulation mechanism 4 is provided on the connecting rod 201. The circulation mechanism 4 includes a connecting frame 401 and an air cylinder 403. The connecting frame 401 is fixedly installed on the lifting rod 204, and a third piston rod 402 is fixedly installed on the connecting frame 401. The piston head of the third piston rod 402 is movably connected to the inside of the air cylinder 403. Through the setting of the circulation mechanism 4, hydrogen gas floating on the upper chamber of the tank 1 can be drawn in and filled into the drinking water of the tank 1, realizing the circulation of hydrogen gas into the water and improving the utilization rate of hydrogen gas.

[0030] The air cylinder 403 is fixedly installed on the inner top wall of the housing 1. A one-way air inlet valve 404 is fixedly installed on the air inlet of the air cylinder 403, and a one-way air outlet valve 405 is fixedly installed on the air outlet of the air cylinder 403. A gas supply pipe 406 is fixedly installed on the one-way air outlet valve 405, and a second nozzle 407 is fixedly installed at the other end of the gas supply pipe 406. The one-way air inlet valve 404 can prevent hydrogen gas that has entered the air cylinder 403 from being discharged from the air inlet, and the one-way air outlet valve 405 can prevent the problem of drinking water backflow.

[0031] Working principle: As the lifting rod 204 moves up and down, it drives the third piston rod 402 to move up and down as well, causing the hydrogen in the upper chamber of the housing 1 to enter the gas cylinder 403. The hydrogen then enters the gas supply pipe 406 through the one-way gas outlet valve 405 and is injected into the drinking water through the second nozzle 407. This process can draw in the hydrogen floating on the surface of the upper chamber of the housing 1 and inject it into the drinking water in the housing 1, thus realizing the circulation of hydrogen into the water and improving the utilization rate of hydrogen.
