Description

Technical Field

[0001] The invention relates to the field of shower heads, and more particularly to a shower head with a filter core that is easy to replace. Background Art

[0002] Shower heads, as one of the indispensable bathroom equipment in modern life, are designed to provide a comfortable and convenient shower experience. They can not only adjust the speed and intensity of the water flow, but also bring users a pleasant bathing experience through their unique spray design. However, with the acceleration of urbanization and the aging of infrastructure, especially the increasingly serious aging and rusting of urban water supply pipelines, as well as the accumulation of impurities and water pollution caused by improper management of intermediate water tanks in high-rise buildings, the quality of tap water sprayed by shower heads is gradually threatened.

[0003] These water quality problems are particularly harmful to certain groups of people, such as the infirm, the elderly, pregnant women and children, whose immune systems are relatively weak and more susceptible to bacteria, viruses and other microorganisms. Therefore, if they come into contact with contaminated water while bathing, the risk of infection will increase significantly. In addition, impurities in the water, such as rust, silt, algae, etc., will directly affect the spray effect of the shower head, causing the spray hole to be blocked, the water flow to be poor, and even damage the internal structure of the shower head, shortening its service life.

[0004] In order to cope with the existing technology of installing filter elements in shower heads, these filter elements are usually made of filter materials, such as activated carbon, ceramics, ultrafiltration membranes, etc., which can effectively remove impurities, residual chlorine, heavy metals and other harmful substances in water.

[0005] However, as the usage time increases, the filter element will gradually accumulate impurities, resulting in reduced filtration efficiency or even complete blockage. This will not only seriously affect the water spraying effect of the shower head, but may also cause damage to the filter element and the inside of the shower head due to the recoil effect of the water flow. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a shower head that is easy to replace the filter element. During the use of the shower head, the scraping component can be driven by water flow power to rotate or reciprocate on the inner wall of the filter element barrel. This design enables the scraping component to effectively push the impurities attached to the inner wall of the filter element barrel to move toward the opening of the collecting component. Subsequently, these impurities smoothly enter the collecting barrel under the guidance of the water flow, thereby realizing automatic cleaning and collection of impurities on the inner wall of the filter element barrel. In addition, the added anti-backflow component can effectively prevent the problem of impurities being scattered from the opening of the collecting barrel due to the shaking of the shower body, thereby ensuring the stability of impurity collection.

[0036] A first cavity 5 is provided inside the shower body 1 at the lower end of the liquid inlet 4, a second cavity 6 is provided inside the shower body 1 at the right side of the first cavity 5, a filter cartridge 10 with one end open is installed in the second cavity 6, a first connecting hole 7 for connecting the first cavity 5 and the second cavity 6 is provided inside the shower body 1, a third cavity 8 is provided at the lower end of the shower body 1, a second connecting hole 9 for connecting the second cavity 6 and the third cavity 8 is provided inside the shower body 1, a shower panel 2 is connected to the lower end opening of the third cavity 8, and a plurality of groups of evenly distributed water outlet holes 3 are provided through the shower panel 2;

[0037] A driving component is installed inside the shower body 1 at the first communicating hole 7, a scraping component is installed inside the filter cartridge 10, and a collecting component is also installed inside the filter cartridge 10. The driving component drives the scraping component to rotate or move back and forth on the inner wall of the filter cartridge 10, and the scraping component pushes the impurities to move toward the opening of the collecting component. A backflow prevention component is installed at the opening of the collecting component. When the driving component is working, the backflow prevention component drives the backflow prevention component to open the opening of the collecting component. A detection component is also installed at the right end of the collecting component, and the detection component is used to detect the amount of impurities in the collecting component.

[0038] The driving component includes a first paddle 13, an annular plate 131 is fixedly connected to the edge of the first paddle 13, a rotating shaft 12 is fixedly connected to the left end of the first paddle 13, the left end of the rotating shaft 12 passes through the first connecting hole 7 and is rotatably connected to the support rod 11, and one end of the support rod 11 away from the rotating shaft 12 is fixedly connected to the inner wall of the first cavity 5, and when water flows through the first connecting hole 7, it pushes the first paddle 13 to rotate;

[0039] The scraping component includes a spiral scraper 141, one end of which is fixedly connected to the annular plate 131;

[0040] The collecting component includes a collecting cylinder 19, which is installed in the filter element cylinder 10, with the opening of the collecting cylinder 19 facing the first paddle 13. An inner filter screen cylinder 20 is installed inside the collecting cylinder 19, and the opening end of the inner filter screen cylinder 20 is fixedly connected to the inner wall of the right end of the collecting cylinder 19. A first drainage hole 21 is penetrated through the right end of the collecting cylinder 19 corresponding to the opening of the inner filter screen cylinder 20. A connecting cylinder 22 is fixedly connected to the left end of the collecting cylinder 19, and the right end of the connecting cylinder 22 is fixedly connected to the inner wall of the filter element cylinder 10. The outer circular wall of the connecting cylinder 22 is penetrated with evenly distributed second drainage holes 23.

[0041] When in use, the liquid inlet 4 is connected to the water inlet pipe, and the water flows into the first cavity 5 through the liquid inlet 4, and then enters the second cavity 6 through the first connecting hole 7. The water flows into the filter cartridge 10. The water flows through the filtration of the filter cartridge 10 and flows to the outside of the filter cartridge 10. The filtered water enters the third cavity 8 through the second connecting hole 9, and then is discharged along the water outlet 3. The discharged water is filtered and sterilized through the filter cartridge 10 to improve the water quality. When the filter cartridge 10 is filtering, its impurities will remain on the inner wall of the filter cartridge 10. When the water flows through the first connecting hole 7, the water flow will drive the first paddle 13 to rotate. When the first paddle 13 rotates, it will drive the annular plate 131 and the spiral scraper 141 to rotate. When the spiral scraper 141 rotates, it will rotate along the inner wall of the filter cartridge 10. When rotating, it will scrape the impurities on the inner wall of the filter cartridge 10 and drive the impurities to pass through the filter cartridge 10. The impurities will move along the inner wall of the filter cartridge 10 to the left end, and finally move to the left end of the filter cartridge 10. The impurities will gather around the first paddle 13, and part of the water flowing out of the first connecting hole 7 will directly flow into the collecting cylinder 19. The water flowing into the collecting cylinder 19 will drive the impurities into the inner collecting cylinder 19 when flowing, so as to collect the impurities. Then the water will be filtered by the inner filter screen cylinder 20, discharged from the first drain hole 21, discharged into the connecting cylinder 22, and finally discharged from the second drain hole 23 to the outside of the collecting cylinder 19, and finally flow into the third cavity 8 through the filter cartridge 10. The inner wall of the filter cartridge 10 is cleaned by the rotation of the spiral scraper 141, so as to avoid the problem of impurities accumulating on the inner wall of the filter cartridge 10 and affecting the water flow rate of the shower head. In addition, the impurities are driven into the collecting cylinder 19 by the continuous water flow into the collecting cylinder 19, so as to realize the automatic collection of impurities. Example 2

[0042] The scraping component also includes a gear 142, which is rotatably installed inside the shower body 1 at a position close to the annular plate 131. The gear 142 is meshed with the annular plate 131. The left end of the gear 142 is fixedly connected to a reciprocating screw rod 143, and an annular scraper 144 is threadedly connected to the reciprocating screw rod 143. The end of the reciprocating screw rod 143 away from the gear 142 is rotatably connected to a first connecting rod 146. The first connecting rod 146 is designed in a curved structure. The end of the first connecting rod 146 away from the reciprocating screw rod 143 is fixedly connected to an optical axis 145, and the end of the optical axis 145 away from the first connecting rod 146 movably passes through the annular scraper 144 and is fixedly connected to the inner wall of the second cavity 6.

[0043] When the annular plate 131 rotates, it drives the meshing gear 142 to rotate. When the gear 142 rotates, it drives the reciprocating screw 143 to rotate. When the reciprocating screw 143 rotates, it drives the annular scraper 144 to move left and right along the reciprocating screw 143. When the annular scraper 144 moves left and right, it pushes the impurities on the inner wall of the filter cartridge 10 to the left and right ends. The impurities at the left end will follow the water flow discharged from the first connecting hole 7 into the collecting cylinder 19 to collect the impurities, and the impurities at the right end will be discharged at the second drainage hole 23. The water will rush to the impurities on the right end, thereby dispersing the impurities on the right end. The dispersed impurities will adhere to the inner wall of the filter cartridge 10 again with the flow of water, and then the attached impurities will be pushed to the first blade 13 by the movement of the annular scraper 144, so that the impurities can enter the collecting barrel 19. By repeating the above operation, the impurities on the inner wall of the filter cartridge 10 can be collected into the collecting barrel 19 as much as possible. Although the scraping component in Example 2 has a certain structural complexity compared to the scraping component in Example 1 when the scheme is implemented, it also provides a feasible implementation plan.

[0044] The detection component includes a second paddle 24, which is installed in the connecting tube 22 and is located opposite to the first drainage hole 21. A sealing cover 34 is provided at the right end opening of the second cavity 6. A knob block 32 is fixedly connected to the right end of the sealing cover 34. A rotating disk 30 is installed inside the knob block 32. An indicator mark 31 is printed on the rotating disk 30. A transparent plate 33 is installed at the position of the knob block 32 corresponding to the rotating disk 30. A connecting component is connected between the second paddle 24 and the rotating disk 30. When the second paddle 24 rotates, the rotating disk 30 is driven to rotate through the connecting component.

[0045] When impurities enter the collecting barrel 19, due to the effect of water flow, the impurities will gather at the right end of the collecting barrel 19. As the collected impurities increase, the impurities will spread to the left end. However, while the impurities are spreading, the filtering area of ​​the inner filter screen barrel 20 will gradually decrease, resulting in less water flow passing through the inner filter screen barrel 20. Then the water discharged from the corresponding first drainage hole 21 will also decrease accordingly. The water discharged from the first drainage hole 21 will drive the second paddle 24 to rotate. When the second paddle 24 rotates, it will synchronously drive the rotating disk 30 to rotate through the connecting parts. The water discharged from the first drainage hole 21 decreases, the flow rate of the water flow decreases, and the corresponding rotation speed of the second paddle 24 will also decrease. By observing the rotation speed of the rotating disk 30, the content of impurities collected in the collecting barrel 19 can be known. The printed indicator 31 on the rotating disk 30 is convenient for the user to observe the rotation effect of the rotating disk 30.

[0046] The anti-backflow component includes an annular barrier 15, which is fixedly installed on the inner wall of the collecting cylinder 19 and close to the opening. The annular barrier 15 is designed with a chamfered angle, and the angle faces the inside of the collecting cylinder 19. A sealing plate 16 is provided on the right side of the annular barrier 15. The right end of the sealing plate 16 is fixedly connected to a first spring 17, and the end of the first spring 17 away from the sealing plate 16 is fixedly connected to the inner filter cylinder 20.

[0047] The water flowing out of the first communicating hole 7 will impact the sealing plate 16. After being impacted, the sealing plate 16 will move to the right and compress the first spring 17. When the sealing plate 16 moves to the right, the opening of the collecting tube 19 will be opened, and impurities will enter the collecting tube 19 along with the water flow. The annular barrier 15 is designed with a chamfered angle, which can facilitate entering the collecting tube 19. When the water flow stops and no longer flows out from the first communicating hole 7, the water flow will no longer impact the sealing plate 16. The previously compressed first spring 17 will push the sealing plate 16 to move to the left, and the sealing plate 16 will be against the annular barrier 15 to close the opening of the collecting tube 19, thereby avoiding the problem of impurities being scattered from the opening of the collecting tube 19 due to the shaking of the shower body 1, thereby ensuring the collection effect of impurities.

[0048] The connecting component includes a second connecting rod 25, which is fixedly connected to the second paddle 24. The end of the second connecting rod 25 away from the second paddle 24 movably passes through the filter cartridge 10 and is fixedly connected to a polygonal column 26. The end of the polygonal column 26 away from the second connecting rod 25 is hemispherical in design. A prism sleeve 27 is provided on the outside of the polygonal column 26. The right end of the prism sleeve 27 is fixedly connected to a third connecting rod 29. The third connecting rod 29 is movably inserted into the interior of the knob block 32 and is fixedly connected to the rotating disk 30.

[0049] A plurality of card slot buckles 36 are fixedly connected to the inner wall of the second cavity 6 near the right end opening. The plurality of card slot buckles 36 are evenly distributed in a ring shape. A card block 35 is provided inside the card slot buckle 36. The card block 35 is fixedly connected to the outer circumferential surface of the sealing cover 34. A sealing rubber ring 37 is also connected to the outer circumferential surface of the sealing cover 34. A second spring 28 is sleeved on the outside of the third connecting rod 29. The left end of the second spring 28 is fixedly connected to the sealing cover 34.

[0050] When using the shower head of the present invention, by observing the rotating disk 30, if it is found that the rotating disk 30 rotates very slowly or does not rotate, it can be determined that the impurities in the collecting tube 19 are full, and the shower head needs to be disassembled to dump the impurities in the collecting tube 19. The user turns the knob block 32, and the knob block 32 rotates, which will drive the clamping block 35 to rotate synchronously. The clamping block 35 will rotate to the opening at the right end of the clamping groove buckle 36. At this time, the knob block 32 is directly pulled to remove the sealing cover 34, and then the filter cartridge 10 can be removed from the second cavity 6, and then one end is pressed against the sealing plate 16 to open the opening of the collecting tube 19. , inject clean water into the gap between the collecting cylinder 19 and the filter element cylinder 10, the clean water will flow into the connecting cylinder 22 from the second drainage hole 23, and then flow into the interior of the inner filter screen cylinder 20 through the first drainage hole 21. Through backwashing cleaning, impurities will flow out from the opening of the collecting cylinder 19. After cleaning, the filter element cylinder 10 is installed into the second cavity 6 as it is, and then pinch the knob block 32 to insert the sealing cover 34 into the right end opening of the second cavity 6, so that the prism sleeve 27 is sleeved in the polygonal prism 26, and the clamping block 35 is inserted into the right end opening of the clamping slot buckle 36. At this time, the second spring 28 pushes the filter element cylinder 10. The left end of the filter cartridge 10 is made to be close to the inner wall of the second cavity 6, and then the knob block 32 is rotated to make the clamping block 35 clamp and enter the clamping groove buckle 36 to fix the sealing cover 34. The installed sealing rubber ring 37 can prevent water from leaking from the connection between the sealing cover 34 and the second cavity 6. This design avoids the problem that the filter screen is set on the shower panel 2 in the prior art, and the shower panel 2 needs to be disassembled when the filter cartridge 10 is disassembled, and the disassembly of the present invention is simple and convenient. In addition, the filter cartridge 10 and the shower panel 2 are separately arranged, which can avoid the problem that a universal filtering shower head in the prior art, application number 201621447312.8, is set at the water diversion cover, which occupies part of the area of ​​the water diversion cover and affects the water outlet area. The present invention avoids the area of ​​the shower panel 2 being occupied, and ensures the shower effect of the user.

[0051] The side wall of the filter cartridge 10 is composed of a filter mesh sleeve 101 and a filler 102. The filler 102 is filled in the filter mesh sleeve 101. The filler 102 is a material for absorbing impurities in water and disinfecting the water. A plurality of groups of support sheets 18 are also provided on the outside of the filter cartridge 10. The support sheets 18 are fixedly mounted on the inner wall of the second cavity 6. The plurality of groups of support sheets 18 are distributed in a ring shape.

[0052] The filler 102 of the present invention can be a mixture of other materials such as activated carbon particles, medical stone particles, negative ion balls, zeolite balls, antibacterial balls, calcium sulfite balls, activated alumina balls, magnetic balls, wooden fish stone balls, VC balls, alkaline metasilicic acid balls, etc. These materials are filled into the filter sleeve 101. When water passes through these fillers 102, the fillers 102 will absorb impurities in the water and disinfect the water. In addition, the installed support sheet 18 prevents the outer wall of the filter cartridge 10 from contacting the inner wall of the second cavity 6, so that the filtering efficiency of the filter cartridge 10 can be ensured, and it is also convenient for the filtered water to flow into the second connecting hole 9, thereby ensuring the water outlet effect of the shower panel 2.

[0053] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
