Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to an automatic water filtration device. Background Technology

[0002] In water supply systems, due to long-term use, the metal pipes of the water supply system will rust and produce iron filings inside, resulting in some suspended particles, iron filings and other impurities in the water supply system pipes. Users can install filtration equipment in the water system to filter out suspended particles, iron filings and other impurities in the water supply system pipes.

[0003] Existing filtration equipment filters impurities in the water circuit through internal filter cartridges. During long-term use, a lot of impurities will accumulate on the outside of the filter cartridges, causing blockages and reducing the filtration efficiency and water flow. This can lead to insufficient water volume in the subsequent water circuits, requiring frequent replacement or cleaning of the filter cartridges for maintenance. Summary of the Invention

[0004] This disclosure relates to an automatic water filtration device. An external support spring supports a central scraper that adheres to an inner filter element. The central scraper effectively cleans impurities, particles, and other substances attached to the outside of the inner filter element. The cleaned substances fall to the bottom of the lower filter cylinder under gravity and gradually accumulate there. This real-time self-cleaning mechanism effectively prevents excessive accumulation of impurities on the surface of the inner filter element, thereby reducing the risk of clogging and extending the effective service life of the inner filter element. The cleaning cycle of the inner filter element is extended, reducing the maintenance workload of replacing or cleaning the filter element.

[0005] In a first aspect, this disclosure provides an automatic water filtration device, specifically comprising: an upper connecting valve body, a lower filter cylinder, and an inner rotating bracket. The lower part of the upper connecting valve body is threadedly connected to the lower filter cylinder, and the inner rotating bracket is disposed inside the lower filter cylinder. An inlet is provided on one side of the upper connecting valve body, and a central connecting pipe is provided in the middle of the upper connecting valve body. The central connecting pipe is connected to the first end of the outlet, and the tail end of the outlet extends to the outside of the upper connecting valve body.

[0006] In at least some embodiments, a drain port is connected to the bottom of the lower filter cylinder, and a valve body is provided at the drain port for opening and closing switching. A lower support is fixedly provided on the bottom inner side of the lower filter cylinder, and an inner filter element is placed on the top of the lower support.

[0007] In at least some embodiments, the inner filter element is located inside the lower filter cylinder, and the space between the inner filter element and the lower filter cylinder is interconnected with the upper connecting valve body and the water inlet.

[0008] In at least some embodiments, the top of the inner filter element and the bottom of the central connecting pipe are fitted and sealed with a sealing ring, and the inner side of the inner filter element, the central connecting pipe, and the water outlet are interconnected. Water enters the central connecting pipe and the water outlet after being filtered by the inner filter element.

[0009] In at least some embodiments, the lower part of the inner rotating bracket is provided with a lower guide fan blade in a ring array, the upper part of the inner rotating bracket is provided with a middle scraper in a ring array, and an outer support spring is fixedly provided on the back of the middle scraper.

[0010] In at least some embodiments, the middle scraper and the inner rotating bracket are slidably connected, and the tail end of the outer support spring is fixedly connected to the inner rotating bracket. After the inner rotating bracket rotates faster, the centrifugal force on the inner rotating bracket and the middle scraper can counteract the supporting force of the outer support spring, so that the middle scraper and the inner filter element are separated and no longer in contact.

[0011] In at least some embodiments, the lower end of the inner rotating bracket and the lower bracket are circumferentially connected. The inner rotating bracket surrounds the outer side of the inner filter element, and the outer support spring supports the middle scraper to fit against the outer side of the inner filter element. During the rotation of the middle scraper, impurities, particles and other substances attached to the outside of the inner filter element are cleaned at the same time. The cleaned substances fall to the bottom of the lower filter cylinder under the action of gravity, preventing excessive accumulation of impurities on the surface of the inner filter element.

[0012] This utility model provides an automatic water filtration device, which has the following beneficial effects:

[0013] The outer support spring supports the middle scraper to fit the inner filter element. The middle scraper effectively cleans impurities, particles and other substances attached to the outside of the inner filter element. The cleaned substances fall to the bottom of the lower filter cylinder under the action of gravity and gradually accumulate at the bottom. Through this real-time self-cleaning mechanism, excessive accumulation of impurities on the surface of the inner filter element is effectively prevented, thereby reducing the risk of clogging of the inner filter element and significantly extending the effective service life of the inner filter element. Because the cleaning cycle of the inner filter element is extended, the maintenance work of frequently replacing or cleaning the filter element is reduced, thus reducing operating costs and maintenance difficulty.

[0014] The rotation speed of the inner rotating support is positively correlated with the water consumption. That is, as the water consumption increases, the rotation speed of the inner rotating support increases accordingly. When the inner rotating support rotates rapidly, the centrifugal force is large enough to counteract the supporting force of the outer support spring, causing the middle scraper to separate from the inner filter element and no longer maintain contact. This design avoids excessive wear caused by the middle scraper continuously rubbing against the inner filter element at high speed under high flow and high speed conditions. Through this adaptive wear protection mechanism, the structural integrity of the inner filter element is effectively protected, further extending the service life of the inner filter element and ensuring the stability and reliability of the equipment during long-term operation.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes an automatic water filtration device, comprising: an upper connecting valve body 1, a lower filter cylinder 2, and an inner rotating support 3. An inlet 101 is connected to one side of the upper connecting valve body 1. A central connecting pipe 102 is provided in the middle of the upper connecting valve body 1, and the first end of the central connecting pipe 102 is connected to the first end of an outlet 103. The tail end of the outlet 103 extends to the outside of the upper connecting valve body 1. The lower filter cylinder 2 is threadedly connected to the lower part of the upper connecting valve body 1. A drain port 201 is provided at the bottom of the lower filter cylinder 2. The bottom of the lower filter cylinder 2 has a constricted conical structure, which guides particles to converge towards the drain port 201. A valve is provided at the drain port 201 for opening and closing. A lower support 202 is fixedly installed at the bottom inner side of the lower filter cylinder 2, and an inner filter element 203 is placed on the top of the lower support 202. The inner filter element 203 is located inside the lower filter cylinder 2. The space between the inner filter element 203 and the lower filter cylinder 2 is connected to the upper connecting valve body 1 and the water inlet 101. The top of the inner filter element 203 and the bottom of the middle connecting pipe 102 are fitted and sealed with a sealing ring. The inner side of the inner filter element 203 is connected to the middle connecting pipe 102 and the water outlet 103. Water enters the middle connecting pipe 102 and the water outlet 103 after being filtered by the inner filter element 203, thus realizing the filtration operation of the user's water. The lower filter cylinder 2 is provided with an inner rotating support 3. The lower part of the inner rotating support 3 is provided with a lower guide fan blade 301 in a ring array. The upper part of the inner rotating support 3 is provided with a middle scraper 302 in a ring array. An outer support spring 303 is fixedly provided on the back of the middle scraper 302. The outer support spring 303 is a metal spring structure.

[0031] In this embodiment, the middle scraper 302 and the inner rotating bracket 3 are slidably connected, and the tail end of the outer support spring 303 is fixedly connected to the inner rotating bracket 3. After the inner rotating bracket 3 rotates faster, the centrifugal force on the inner rotating bracket 3 and the middle scraper 302 can counteract the supporting force of the outer support spring 303, so that the middle scraper 302 and the inner filter element 203 are separated and no longer in contact, thus avoiding excessive wear caused by high-speed friction between the middle scraper 302 and the inner filter element 203.

[0032] In this embodiment, the lower end of the inner rotating bracket 3 and the lower bracket 202 are circumferentially rotatably connected. The inner rotating bracket 3 surrounds the outer side of the inner filter element 203. The outer support spring 303 supports the middle scraper 302 to fit against the outer side of the inner filter element 203. During the rotation of the middle scraper 302, it simultaneously cleans impurities, particles and other substances attached to the outside of the inner filter element 203. The cleaned substances fall to the bottom of the lower filter cylinder 2 under the action of gravity, preventing excessive accumulation of impurities on the surface of the inner filter element 203, reducing the risk of clogging of the inner filter element 203, and extending the service life of the inner filter element 203.

[0033] In Example 2, based on Example 1, the drain outlet 201 is connected to a pressure valve. When the pressure increases due to poor filtration in the lower filter cylinder 2, the pressure valve of the drain outlet 201 automatically opens to discharge particulate matter, eliminating the need for the user to manually open the drain outlet 201 valve, making it more convenient to use.

[0034] The working principle of this embodiment is as follows: the inlet 101 is connected to the water inlet pipe of the water supply system, and the outlet 103 is connected to the user's water pipe. Water enters the lower filter cylinder 2 through the inlet 101. After being filtered by the inner filter element 203, the water enters the middle connecting pipe 102 and the outlet 103, thus achieving the filtration operation of the user's water. Impurities, particles, and other substances are attached to the outside of the inner filter element 203. The water flow drives the lower guide fan blade 301 to rotate. The lower guide fan blade 301 and the inner rotating support 3 rotate synchronously. The outer support spring 303 provides support for the middle scraper 302, ensuring that the outer support spring 303 supports the middle scraper 302 close to the inner filter element 203. The central scraper 302 adheres to the outer surface of the inner filter element 203. During the rotation of the central scraper 302, it simultaneously cleans impurities, particles, and other substances attached to the outside of the inner filter element 203. The cleaned-off substances fall to the bottom of the lower filter cylinder 2 under the action of gravity and gradually accumulate at the bottom. The drain port 201 is manually opened periodically to drain the wastewater. Through this self-cleaning mechanism, it effectively prevents excessive accumulation of impurities on the surface of the inner filter element 203, thereby reducing the risk of clogging of the inner filter element 203 and further extending the effective service life of the inner filter element 203. The cleaning cycle of the inner filter element 203 is extended, reducing the replacement or cleaning maintenance work of the inner filter element 203, and reducing operating costs and maintenance difficulty.

[0035] The rotation speed of the inner rotating support 3 is positively correlated with the water consumption. As the water consumption increases, the rotation speed of the inner rotating support 3 will also increase. When the rotation speed of the inner rotating support 3 increases, the centrifugal force of the inner rotating support 3 and the middle scraper 302 will also increase. The centrifugal force can counteract the supporting force of the outer support spring 303, causing the middle scraper 302 to separate from the inner filter element 203 and no longer maintain contact. This design avoids excessive wear caused by the middle scraper 302 due to continuous high-speed friction with the inner filter element 203 under high flow and high speed conditions. Through this adaptive wear protection mechanism, the structural integrity of the inner filter element 203 is effectively protected, further extending the service life of the inner filter element 203 and ensuring the stability and reliability of the equipment during long-term operation.
