Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment for water dispensers, and in particular to a filter for a water dispenser and a use method thereof. Background Art

[0002] Most of the water bodies in the world are seriously polluted, which exacerbates the contradiction of water shortage. Traditional tap water treatment methods can no longer guarantee the provision of high-quality drinking water, and there is also the problem of secondary pollution in municipal water supply, such as high-rise water tank water supply and long tap water pipelines, which will cause potential pollution problems such as rust, sediment and microorganisms. The tap water for daily drinking has undergone a variety of cleaning, sterilization and disinfection methods. After the factory water quality test, it can meet the national health standards, and then flows into thousands of households through long pipes and secondary pressurized water tanks. Before flowing into households, the long pipelines have passed through complex terrain and roads. Some pipes have been in disrepair for a long time, some water pipes cross with sewage pipes, and some water pipes in the building even have to pass through the toilet before they can reach the kitchen. Because of the leakage around the water pipes and the seldom cleaning and disinfection of the secondary pressurized water tanks, the water tanks cannot be spotless, and the rust in the water pipes and many other reasons will cause secondary pollution to the water quality. After further testing, rust, lead and pesticides all appear to varying degrees, and the pollution situation may be shocking.

[0003] Under the existing technology, water dispenser filters usually use replaceable filter elements of different materials to filter tap water. When replacing the filter element, since tap water contains a large amount of minerals, a large amount of calcification will accumulate at the connection between the filter element and the filter after long-term use, causing the filter element to stick to the outer wall of the filter, making it difficult to remove the old filter element.

[0014] A method for using a filter for a water dispenser comprises the following steps:

[0015] Step 1: Install the filter. When using the filter for the water dispenser, first install the filter element inside the filter cover, put the filter element into the filter cover through the filter cover on the top of the filter cover, and then install the filter cover on the top of the filter cover with threads. At this time, the filter cover presses the sliding sleeve inside the filter cover downward along the filter cover, and the sliding sleeve is pressed and slides down along the sliding rod. At this time, the sliding sleeve drives the clamping arc piece at one end of the fixed telescopic rod on the sliding ring to squeeze the side wall of the filter element;

[0016] Step 2: Filter water. The water is transported to the control pipe at the bottom of the drainage tube through the drainage pipe at the bottom of the last filter cover. Under the push of the high pressure of the water, the high pressure water pushes the control piston to slide downward along the control pipe. When the control piston slides to the bottom of the control pipe, the water inside the control pipe enters the water storage tank through the limit elbow for storage. When the water inside the water storage tank is gradually filled, the water pressure inside the water storage tank gradually equals the water pressure inside the drainage tube, and the control piston returns to its initial position.

[0017] Step 3: Clean the outer wall of the filter element. The push rod slides downward to drive the scraper ring to slide downward along the sliding cavity. The inner wall of the scraper ring contacts the outer wall of the filter element. At this time, the inner wall of the scraper ring rubs against the outer wall of the filter element.

[0018] Step 4: Seal the filter element, push the piston downward to drive the sealing piston on the push rod to slide downward along the gas chamber. At this time, the sealing piston squeezes the gas inside the gas chamber into the annular airbag through the air inlet pipe. At this time, the annular airbag expands and is in close contact with the side wall of the filter element.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a sliding cleaning mechanism. When the water storage tank of the filter is full of water, the water pressure inside the water storage tank is equal to the water pressure inside the filter cover. When a person drains water through the water outlet tap at the bottom of the water storage tank, the water pressure inside the water storage tank decreases. The water pressure inside the high-pressure water cylinder at one end of the high-pressure water pipe is greater than the water pressure inside the water storage tank at the bottom of the connecting pipe 2. At this time, the high-pressure water inside the high-pressure water cylinder is transported to the top of the sliding pipe through the connecting pipe 3. The high-pressure water squeezes the pushing piston inside the sliding pipe to slide downward. The pushing piston slides downward and drives the pushing rod to slide downward along the sealing tube. The pushing rod slides downward and drives the scraper ring to slide downward along the sliding cavity. The inner wall of the scraper ring contacts the outer wall of the filter element. At this time, the inner wall of the scraper ring rubs against the outer wall of the filter element. This arrangement is conducive to ensuring that the scraper ring can scrape the outer wall of the filter element every time water is taken, which is conducive to avoiding a large amount of calcification remaining on the outer wall of the filter element.

[0021] (2) According to the present invention, when the filter for a water dispenser is used, the filter element is first installed inside the filter cover, and the filter element is placed inside the filter cover through the filter cover on the top of the filter cover. At this time, the filter cover is threadedly installed on the top of the filter cover. At this time, the filter cover presses the sliding sleeve inside the filter cover downward along the filter cover. The sliding sleeve is pressed downward along the slide rod. At this time, the sliding sleeve drives the clamping arc piece at one end of the fixed telescopic rod on the sliding ring to squeeze the side wall of the filter element. At this time, the clamping arc piece presses the reset spring inward along the limit rod. Such a setting is conducive to fixing the filter element inside the filter cover, preventing the filter element from shaking when filtering water, and improving the filtering quality of the filter element.

[0022] (3) According to the present invention, after the filter element is installed, the external water pipe is fixedly connected to the top of the water inlet pipe. At this time, the water is pressurized by the booster pump and sent into the interior of the filter cover. The water passing through the first filter cover is then transported to the interior of the next filter cover through the filter water pipe at the bottom of the filter cover. This arrangement is conducive to multi-stage filtration of water, thereby improving the water purification quality of the filter. In addition, the water is pressurized by the booster pump and sent into several filter covers, which is conducive to accelerating the filtration speed of the filter; the water is transported to the control pipe at the bottom of the drainage tube through the drainage pipe at the bottom of the last filter cover. Under the push of the high pressure of the water, the high-pressure water pushes the control piston to slide downward along the control pipe. When the control piston slides to the bottom of the control pipe, the water in the control pipe enters the water storage tank through the limit bend pipe for storage. When the water in the water storage tank is gradually filled, the water pressure in the water storage tank gradually becomes equal to the water pressure in the drainage tube. At this time, the control piston returns to its initial position.

[0023] (4) The present invention sets a sealing mechanism. When the water pressure inside the water tank decreases, the water pressure inside the high-pressure water cylinder at one end of the high-pressure water pipe is greater than the water pressure inside the water tank at the bottom of the connecting pipe 2. At this time, the high-pressure water inside the high-pressure water cylinder is transported to the top of the sliding tube through the connecting pipe 3. The high-pressure water squeezes the pushing piston inside the sliding tube to slide downward. The pushing piston slides downward and drives the sealing piston on the pushing rod to slide downward along the gas cavity. At this time, the sealing piston squeezes the gas inside the gas cavity into the annular airbag through the air inlet pipe. At this time, the annular airbag expands and is in close contact with the side wall of the filter element. This arrangement is conducive to enhancing the tightness between the filter element and the filter cover, ensuring that the filtered water enters the bottom of the filter cover through the filter element. When the filter element returns to the top of the gas cavity, the gas inside the annular airbag is reduced, and the inner wall of the annular airbag is separated from the side wall of the filter element. This arrangement is not conducive to the generation of calcification between the annular airbag and the filter element.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the high-pressure water inside the high-pressure water cylinder 409 is transported to the top of the sliding tube 405 through the connecting pipe 3 410, and the high-pressure water squeezes the pushing piston 406 inside the sliding tube 405 to slide downward, pushing the piston 406 to slide downward, driving the pushing rod 403 to slide downward along the sealing tube 404, and the pushing rod 403 slides downward to drive the scraper ring 402 to slide downward along the sliding cavity 401, and the inner wall of the scraper ring 402 contacts the outer wall of the filter element 206. At this time, the inner wall of the scraper ring 402 rubs against the outer wall of the filter element 206. This arrangement is conducive to ensuring that the scraper ring 402 can scrape the outer wall of the filter element 206 every time water is taken, which is conducive to avoiding a large amount of calcification remaining on the outer wall of the filter element 206.

At this time, the sealing piston 502 squeezes the gas inside the gas chamber 501 through the air inlet pipe 503 into the annular airbag 504. At this time, the annular airbag 504 expands and is in close contact with the side wall of the filter element 206. This arrangement is conducive to enhancing the tightness between the filter element 206 and the filter cover 202, ensuring that the filtered water enters the bottom of the filter cover 202 through the filter element 206. When the filter element 206 returns to the top of the gas chamber 501, the gas inside the annular airbag 504 is reduced, and the inner wall of the annular airbag 504 is separated from the side wall of the filter element 206. This arrangement is not conducive to the generation of calcification between the annular airbag 504 and the filter element 206.

[0048] A method for using a filter for a water dispenser comprises the following steps:

[0049] Step 1: Install the filter. When using the filter for the water dispenser, first install the filter element 206 inside the filter cover 202, and put the filter element 206 into the filter cover 202 through the filter cover 203 on the top of the filter cover 202. At this time, the filter cover 203 is threadedly installed on the top of the filter cover 202. At this time, the filter cover 203 presses the sliding sleeve 208 inside the filter cover 202 downward along the filter cover 202. The sliding sleeve 208 is pressed and slides down along the sliding rod 207. At this time, the sliding sleeve 208 drives the clamping arc piece 212 at one end of the fixed telescopic rod 211 on the sliding ring 210 to squeeze the side wall of the filter element 206;

[0050] Step 2: Filter water. The water is transported to the control pipe 303 at the bottom of the drainage tube 302 through the drainage pipe 301 at the bottom of the last filter cover 202. Under the push of the high pressure of the water, the high pressure water pushes the control piston 304 to slide downward along the control pipe 303. When the control piston 304 slides to the bottom of the control pipe 303, the water inside the control pipe 303 enters the water storage tank 18 through the limit elbow 306 for storage. When the water inside the water storage tank 18 is gradually filled, the water pressure inside the water storage tank 18 gradually becomes equal to the water pressure inside the drainage tube 302. At this time, the control piston 304 returns to its initial position.

[0051] Step 3: Clean the outer wall of the filter element 206. The push rod 403 slides downward to drive the scraper ring 402 to slide downward along the sliding cavity 401. The inner wall of the scraper ring 402 contacts the outer wall of the filter element 206. At this time, the inner wall of the scraper ring 402 rubs against the outer wall of the filter element 206.

[0052] Step 4: Seal the filter element 206, push the piston 406 to slide downward, and drive the sealing piston 502 on the push rod 403 to slide downward along the gas chamber 501. At this time, the sealing piston 502 squeezes the gas inside the gas chamber 501 through the air inlet pipe 503 into the annular airbag 504. At this time, the annular airbag 504 expands and is in close contact with the side wall of the filter element 206.

[0053] A specific application of this embodiment is:

[0054] When using the filter for a water dispenser, first install the filter element 206 inside the filter cover 202, and put the filter element 206 into the filter cover 202 through the filter cover 203 on the top of the filter cover 202. At this time, the filter cover 203 is threadedly installed on the top of the filter cover 202. At this time, the filter cover 203 presses the sliding sleeve 208 inside the filter cover 202 downward along the filter cover 202. The sliding sleeve 208 is pressed downward along the slide rod 207 to press the slide rod 207. At this time, the sliding sleeve 208 The clamping arc piece 212 at one end of the fixed telescopic rod 211 on the sliding ring 210 is driven to squeeze the side wall of the filter element 206. At this time, the clamping arc piece 212 squeezes the return spring 214 inward along the limit rod 213. This arrangement is conducive to fixing the filter element 206 inside the filter cover 202, preventing the filter element 206 from shaking when filtering water, and improving the filtering quality of the filter element 206. After the filter element 206 is installed, the external water pipe is fixedly connected to the top of the water inlet pipe 12. At this time, water passes through the booster pump 2 04 pressurizes water and sends it into the filter cover 202. The water that passes through the first filter cover 202 is then transported to the next filter cover 202 through the filter water pipe 205 at the bottom of the filter cover 202. This arrangement is conducive to multi-stage filtration of water, thereby improving the water purification quality of the filter. In addition, the water is pressurized by the booster pump 204 and sent to several filter covers 202, which is conducive to accelerating the filtration speed of the filter; the water is transported to the control pipe 303 at the bottom of the drainage tube 302 through the drainage pipe 301 at the bottom of the last filter cover 202. Under the push of the high pressure of the water, the high-pressure water pushes the control piston 304 to slide downward along the control pipe 303. When the control piston 304 slides to the bottom of the control pipe 303, the water in the control pipe 303 enters the water storage tank 18 through the limit bend 306 for storage. When the water in the water storage tank 18 is gradually filled, the water pressure in the water storage tank 18 gradually becomes equal to the water pressure in the drainage tube 302. At this time, the control piston 304 returns to its initial position;

[0055] By setting the sliding cleaning mechanism 4, when the water storage tank 18 of the filter is full of water, the water pressure inside the water storage tank 18 is equal to the water pressure inside the filter cover 202. When the personnel releases water through the water outlet tap 19 at the bottom of the water storage tank 18, the water pressure inside the water storage tank 18 decreases, and the water pressure inside the high-pressure water cylinder 409 at one end of the high-pressure water pipe 408 is greater than the water pressure inside the water storage tank 18 at the bottom of the connecting pipe 2 407. At this time, the high-pressure water inside the high-pressure water cylinder 409 is transported to the top of the sliding pipe 405 through the connecting pipe 3 410, and the high-pressure water squeezes the inside of the sliding pipe 405. The piston 406 is pushed to slide downward, and the piston 406 is pushed downward to drive the push rod 403 to slide downward along the sealing tube 404. The push rod 403 slides downward to drive the scraper ring 402 to slide downward along the sliding cavity 401. The inner wall of the scraper ring 402 contacts the outer wall of the filter element 206. At this time, the inner wall of the scraper ring 402 and the outer wall of the filter element 206 rub against each other. This arrangement is conducive to ensuring that the scraper ring 402 can scrape the outer wall of the filter element 206 every time water is taken, which is conducive to avoiding a large amount of calcification remaining on the outer wall of the filter element 206. By setting a sealing Mechanism 5, when the water pressure inside the water tank 18 decreases, the water pressure inside the high-pressure water cylinder 409 at one end of the high-pressure water pipe 408 is greater than the water pressure inside the water tank 18 at the bottom of the connecting pipe 2 407. At this time, the high-pressure water inside the high-pressure water cylinder 409 is transported to the top of the sliding pipe 405 through the connecting pipe 3 410. The high-pressure water squeezes the push piston 406 inside the sliding pipe 405 to slide downward. The push piston 406 slides downward and drives the sealing piston 502 on the push rod 403 to slide downward along the gas chamber 501. At this time, the sealing piston 502 squeezes the gas chamber 501. The gas enters the annular airbag 504 through the air inlet pipe 503. At this time, the annular airbag 504 expands and is in close contact with the side wall of the filter element 206. This arrangement is conducive to enhancing the tightness between the filter element 206 and the filter cover 202, ensuring that the filtered water enters the bottom of the filter cover 202 through the filter element 206. When the filter element 206 returns to the top of the gas cavity 501, the gas inside the annular airbag 504 is reduced, and the inner wall of the annular airbag 504 is separated from the side wall of the filter element 206. This arrangement is not conducive to the formation of calcification between the annular airbag 504 and the filter element 206.
