Description

Technical Field

[0001] The invention relates to the field of water purification equipment, and in particular to a self-cleaning energy-saving tap water purification equipment. Background Art

[0002] At present, when cleaning the ceramic filter element water purifier, the water purification device is disassembled and the dirt on the ceramic filter element cleaned by a scraper or brush is washed away with clean water to restore its permeability. However, after using such filter elements, the water purification device needs to be manually disassembled for cleaning in 1-2 weeks, which is troublesome to operate and manual cleaning is easy to damage the filter element because the strength is difficult to control; To this end, the prior art sets a cleaning mechanism inside the water purification device and uses water pressure to drive the corresponding cleaning mechanism to automatically clean the ceramic filter element. However, no matter what kind of cleaning mechanism is set, the dirt after cleaning still remains in the water in the water purification device. Generally, most water purification devices are usually only designed with an inlet end and an outlet end. In order to discharge the water containing dirt, a drain valve needs to be specially designed. This means that in order to complete the entire process from self-cleaning to draining, manual intervention is still required to clean the drain valve, and true self-cleaning, that is, automatic cleaning and automatic draining, cannot be achieved. In addition, the prior art also uses the water inlet end to take into account the input of tap water and the discharge of water with dirt. However, in the process of discharging the water with dirt, some dirt will still remain in the pipe at the water inlet end, and the next time tap water is input, the dirt will be brought back to the water purification device. Therefore, it is necessary to design a water purification device that can automatically discharge water with dirt after completing self-cleaning. Summary of the invention

[0003] The purpose of the present invention is to provide a self-cleaning energy-saving tap water purification device to solve the problem that although the existing water purification device can complete the self-cleaning of the ceramic filter element, the dirt cleaned from the ceramic filter element is still in the water purification device and mixed in the water, and manual intervention is still required for cleaning by setting a sewage valve, etc. If the water inlet end takes into account both inputting tap water and discharging water with dirt, some dirt will still remain in the pipe of the water inlet end, and the next time tap water is input, the dirt will be brought back to the water purification device. The specific technical solution is as follows: An energy-saving tap water purification device with self-cleaning function. The purification device is externally connected to a tap water pipeline and includes a housing, a drainage part, a valve, and a cleaning and sewage removal component driven by water flow. The housing is provided with an outlet and a sewage outlet. The valve is installed at the sewage outlet. The cleaning and sewage removal component is arranged in the housing. The drainage part is elastically telescopic and arranged in the housing, and the drainage part is arranged above the cleaning and sewage removal component. The drainage part is connected to the valve. By blocking the outlet, the internal pressure of the housing is increased to squeeze the drainage part. The valve is associated with the drainage part, and the valve immediately opens the sewage outlet or delays closing the sewage outlet according to the telescopic degree of the drainage part.

[0004] As an improvement of the above technical solution, a filter element is rotatably connected to the housing. The filter element is arranged at the outlet. The cleaning and sewage removal component is sleeved outside the filter element. A convex part is provided at the top of the filter element. The convex part passes through the cleaning and sewage removal component and is connected to a water wheel.

[0005] As an improvement of the above technical solution, the cleaning and sewage removal component includes a bracket and bristles connected to the inner side of the bracket. The filter element is arranged in the bracket, and the bristles are in contact with the outer side of the filter element.

[0006] As an improvement of the above technical solution, the drainage part includes a pressing block, a support rod, and a spring. The support rod is connected to the pressing block. The support rod is slidably connected to the inside of the housing. The spring is sleeved outside the support rod. The two ends of the spring are respectively connected to the pressing block and the inner wall of the housing.

[0007] As an improvement of the above technical solution, the sewage outlet is tubular. A groove is provided on the inner wall of the sewage outlet for accommodating the valve. A movable rod is connected to the top of the valve. The movable rod passes through the sewage outlet and the housing and is connected to the support rod. The valve makes a reciprocating up and down movement driven by the telescopic movement of the drainage part.

[0008] As an improvement of the above technical solution, the valve includes a sliding part. The sliding part is provided with a chute. The notch of the chute is narrowed. The end of the movable rod passes through the notch of the chute and enters the chute. A convex is provided on the outer side of the end of the movable rod.

[0009] As an improvement of the above technical solution, a magnet is embedded on the inner wall of the sewage outlet. A metal layer that can be magnetically adsorbed is provided inside the sliding part.

[0010] As an improvement of the above technical solution, the metal layer is provided inside the top surface of the sliding part. The magnetic field range of the magnet covers the upper half of the inside of the sewage outlet.

[0011] As an improvement of the above technical solution, an airbag is provided on the outer side of the bottom of the sliding member, and the notch of the groove gradually contracts from top to bottom.

[0012] Advantages of the present invention: By providing a valve in cooperation with the drainage part, only by blocking the outlet, self-cleaning of the filter element can be achieved, and at the same time, the valve can be automatically opened to discharge the water with dirt. At this time, although the drainage part will drop, it does not affect the sewage outlet in the early stage of the drop of the drainage part. Only when the drainage part drops to a certain height will the sewage outlet gradually close, that is, delayed closing is realized, so that the water with dirt can flow out of the housing. The present invention directly uses the water flow energy of the water purification device to drive the sewage cleaning component, avoiding the consumption of electric energy or hydraulic energy, reducing the overall energy consumption of the device, and being more energy-saving and environmentally friendly compared with the equipment equipped with an additional driving mechanism.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Although the existing water purification equipment can complete the self-cleaning of the ceramic filter element, the dirt cleaned from the ceramic filter element is still in the water purification equipment and mixed in the water. It still needs manual intervention to clean it by setting a sewage valve. If the water inlet is used to take into account both the input of tap water and the discharge of water with dirt, some dirt will still remain in the pipe at the water inlet in the process of discharging the water with dirt. The next time tap water is input, the dirt will be brought back to the water purification device; See also Figures 1-6 The present invention provides some embodiments to solve the above problems, specifically including a housing 1, a drainage part 2, a valve 3 and a cleaning component 4 driven by water flow, wherein the housing 1 is provided with an inlet 11, an outlet 12 and a sewage outlet 13, the inlet 11 is used to connect to an external tap water pipe, the interior of the housing 1 is also rotatably connected with a filter element 5, the filter element 5 is arranged on the outlet 12, and the normal filtering method is: connect the inlet 11 with the tap water pipe, turn on the switch controlling the tap water pipe, such as a faucet, the tap water flows into the housing 1 through the inlet 11, and the tap water is filtered by the filter element 5 and then flows out from the outlet 12, completing the filtering; In the above process, since the present invention is mainly applied to the ceramic filter element 5, the micron-level pores (usually 0.5-1 μm) of the ceramic filter element 5 block the suspended particles, colloidal substances and microorganisms in the water through physical screening. These impurities accumulate on the surface of the filter element 5 to form a visible dirt layer. In the initial stage of filtration, when the water flows through the filter element 5 under pressure (3-5 bar), large particle impurities are directly blocked by the pores to form an initial dirt layer. After long-term use, small molecular impurities (such as soluble minerals) that are not completely filtered continue to precipitate on the surface of the filter element 5 due to the concentration gradient, and the dirt layer gradually thickens, which may block part of the pores, so it is necessary to use a scraper or a brush to clean the dirt. To this end, the present invention provides a dirt cleaning component 4 that does not require an additional driving mechanism and uses water flow to drive and clean the filter element 5. It directly utilizes the kinetic energy of the water flow of the water purification device to drive the dirt cleaning component 4, avoiding the consumption of electric energy or hydraulic energy, reducing the overall energy consumption of the device, and being more energy-saving and environmentally friendly compared to being equipped with an additional driving mechanism. Specifically, the dirt cleaning component 4 is arranged in the housing 1, the drainage part 2 is elastically telescopic and arranged in the housing 1, and the drainage part 2 is arranged above the dirt cleaning component 4. The top of the filter element 5 is provided with a protruding part, the protruding part passes through the dirt cleaning component 4 and is connected with a water wheel 6. The dirt cleaning component 4 includes a bracket 41 and bristles 42 connected to the inner side of the bracket 41. The filter element 5 is arranged inside the bracket 41 or the bracket 41 is sleeved outside the filter element 5, and the bristles 42 are in contact with the outer side of the filter element 5. Its working principle is that during the process of water flow passing through the water wheel 6, it will drive the water wheel 6 to rotate. The rotation of the water wheel 6 will drive the filter element 5 to rotate relative to the bracket 41. It can be understood that since the filter element 5 is not required for filtration at this time, the rotation of the filter element 5 will not cause any impact. During the rotation of the filter element 5, the inner bristles 42 of the bracket 41 will rub against the surface of the filter element 5 to clean the dirt on the surface of the filter element 5. Preferably, this solution is not limited to the rotation of the filter element 5. In some embodiments, the filter element 5 is fixedly connected to the inside of the housing 1, the bracket 41 is rotatably connected to the housing 1, and the water wheel 6 is connected to the top of the bracket 41. Similarly, it can be realized that the water flow is used to drive the water wheel 6 to drive the bracket 41 to rotate relative to the filter element 5, and the cleaning of the filter element 5 can also be realized. Considering that the dirt cleaned off is still inside the water purification device and mixed in the water, and manual intervention is still required for cleaning by setting a sewage discharge valve, therefore, the present invention also provides some embodiments to solve the above problems. Specifically, The valve 3 is installed at the sewage discharge port 13, the drainage part 2 is connected to the valve 3. By blocking the outlet 12, the pressure inside the housing 1 is increased and the drainage part 2 is squeezed. The valve 3 is associated with the drainage part 2, and the valve 3 immediately opens the sewage discharge port 13 or delays closing the sewage discharge port 13 according to the telescopic degree of the drainage part 2.

[0025] It should be noted that in the above embodiments, since the drainage part 2 of the present invention is directly connected to the valve 3, therefore, when the drainage part 2 is squeezed to a certain extent, that is, during the process of the drainage part 2 being squeezed and moving upward, it will also drive the valve 3 to move upward. Therefore, the opening of the valve 3 is actually synchronized with the squeezed drainage part 2. In this embodiment, the valve 3 gradually moves upward and gradually opens the sewage discharge port 13, corresponding to the above-mentioned valve 3 immediately opening the sewage discharge port 13 according to the telescopic degree of the drainage part 2. When the sewage outlet 13 is opened, the water inside the housing 1 will be released. At this time, the pressure inside the housing 1 decreases and is insufficient to support or squeeze the drainage part 2. The squeezed drainage part 2 is in an elastic energy storage state and will squeeze the water inside the housing 1 during the release process, accelerating the flow of the water inside the housing 1. At this time, the flow rate of the water flowing through the water wheel 6 increases, and the rotation speed of the water wheel 6 and the filter element 5 becomes faster; However, since the drainage part 2 is directly connected to the valve 3, that is, the movement of the drainage part 2 and the valve 3 is synchronized. If the valve 3 is not improved or simply adopts the traditional valve 3 structure, another problem will be faced: during the drainage process, the downward movement of the drainage part 2 will also drive the valve 3 to descend. At this time, the water inside the housing 1 has not been drained and the valve 3 begins to close gradually. And based on the above self-cleaning working principle, it can be known that when the sewage outlet 13 is opened, the cleaning component 4 starts to clean. Most of the dirt will be mixed in the subsequent water flow. Therefore, when the drainage part 2 descends, the valve 3 needs to close later, rather than gradually closing synchronously with the drainage part 2. The synchronous drainage part 2 will block the water flowing out with most of the dirt mixed in it. For this reason, the present invention also provides some embodiments, specifically: The drainage part 2 includes a squeezing block 21, a support rod 23 and a spring 22. The support rod 23 is connected to the squeezing block 21. The support rod 23 is slidably connected to the inside of the housing 1. The spring 22 is sleeved outside the support rod 23. The two ends of the spring 22 are respectively connected to the squeezing block 21 and the inner wall of the housing 1. The sewage outlet 13 is tubular. The inner wall of the sewage outlet 13 is provided with a groove for receiving the valve 3. The top of the valve 3 is connected with a movable rod 33. The movable rod 33 passes through the sewage outlet 13 and the housing 1 and is connected to the support rod 23. The up and down reciprocating movement of the valve 3 is driven by the expansion and contraction of the drainage part 2. Preferably, an accommodation space is provided inside the housing 1 for receiving the movable rod 33. The top of the movable rod 33 is bent and connected to the support rod 23, so that the squeezing block 21 can move synchronously with the valve 3; The valve 3 includes a sliding member 31. The sliding member 31 is provided with a chute. The notch of the chute is narrowed. The end of the movable rod 33 passes through the notch of the chute and enters the chute. A protrusion is provided on the outer side of the end of the movable rod 33. A magnet 7 is embedded on the inner wall of the sewage outlet 13. A metal layer 311 that can be magnetically adsorbed is provided inside the sliding member 31. The metal layer 311 is provided inside the top surface of the sliding member 31, and the magnetic field range of the magnet 7 covers the upper half of the inside of the sewage outlet 13.

[0026] The specific working principle is as follows: Connect the inlet 11 of the housing 1 to the tap water pipe externally so that the housing 1 receives tap water. When it is necessary to self-clean the water purification device, block the outlet 12 (for example, a end cap is threadedly connected to the outlet 12). Tap water is continuously injected into the interior of the housing 1, increasing the pressure inside the housing 1. Or rather, as the tap water is injected, the water level inside the housing 1 continuously rises and squeezes the extrusion block 21. The water exerts an upward force on the extrusion block 21, and the extrusion block 21 then squeezes the spring 22 and drives the support rod 23 to move upward. During the upward movement of the support rod 23, it will drive the movable rod 33 to move upward. By default, the sliding member 31 is arranged in the groove, and the sliding member 31 and the movable rod 33 (wide enough to cover the sewage outlet 13) will block and close the sewage outlet 13. As the movable rod 33 moves upward, the movable rod 33 will drive the sliding member 31 to move upward. When the top of the sliding member 31 enters the upper half of the sewage outlet 13, that is, when it enters the adsorption range of the magnet 7, the sliding member 31 moves upward along the movable rod 33 under the attraction of the magnet 7 and adsorbs at the magnet 7; During the upward movement of the movable rod 33 and the sliding member 31, it is equivalent to opening the sewage outlet 13, and the water inside the housing 1 will flow out along the sewage outlet 13. At this time, the extrusion block 21 will descend downward and synchronously drive the movable rod 33 to move downward. Since the sliding member 31 is adsorbed on the magnet 7 at this time, the downward movement of the movable rod 33 at the beginning will not affect the sliding member 31. It is necessary when the movable rod 33 descends to a certain extent, that is, when the bottom surface of the movable rod 33 abuts against the bottom surface of the chute of the sliding member 31, the movable rod 33 will push the sliding member 31, separating the sliding member 31 from the magnet 7, and then drive the sliding member 31 to move downward until the sliding member 31 enters the groove and closes the sewage outlet 13 again; Preferably, an airbag 32 is provided on the outer side of the bottom of the sliding member 31, and the notch of the groove gradually contracts from top to bottom. By providing the airbag 32, the sealing effect of the valve 3 can be strengthened. Secondly, when water flows through the bottom of the sliding member 31, the airbag 32 can float by buoyancy to ensure that when the sewage outlet 13 needs to be opened, the sewage outlet 13 can be fully opened.

[0027] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
