Description

Technical Field

[0001] The invention relates to the technical field of shower heads, in particular to a sediment flushing structure of a water purification cartridge in a shower head with a water purification function. Background Art

[0002] A shower head is a shower device that disperses water into fine particles and is primarily used for cleansing. Through the nozzle, it evenly distributes water to various parts of the body, helping to cleanse the skin and remove dirt. Shower heads typically feature multiple water patterns (such as rain shower and massage shower) to meet diverse showering needs. Because showers are used for cleansing, the water delivered is typically a mixture of hot and cold water to a specified temperature. Heating water creates scale and contains impurities, which can remain inside the shower head during showering. This can lead to clogging of the nozzle after prolonged use, necessitating the installation of a filter cartridge within the shower head.

[0003] The filter holes in the filter cartridge inside the existing shower head will still be clogged after long-term use, and the existing shower head cannot automatically clean the impurities inside it when in use. The staff needs to manually disassemble the shower head shell to clean the impurities inside it. Cleaning the impurities during use is rather cumbersome. At the same time, when the staff uses the shower head to clean the body, the shower head water will be stopped for better cleaning, and body lotion, fragrance liquid, etc. will be manually applied on the body surface. The existing shower head cannot add other fragrance liquid or cleaning liquid in real time when the shower water is sprayed according to the usage situation, resulting in a longer shower time and lower shower efficiency for the staff.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the filter housing is closed, the water in the filter housing is automatically pushed open, and the water in the filter housing is automatically pushed open to discharge the water from the filter housing to the outside through the drainage holes, and the filter housing is automatically cleaned during the discharge.

[0016] When the water between the bottom of the filter shell and the bottom of the fixed shell in the present invention is cleaned into the filter hole, it can be simultaneously transported to the first water delivery hole and the filter hole at the bottom of the filter shell. When cleaning impurities inside the shell, several nozzles can still spray water, but the water volume and spraying intensity are reduced, which can remind the staff who are in the shower. After the impurities inside the shell are cleaned, it is convenient for the staff to install the lifting plate in time. When the water volume of the nozzle is reduced to remind the staff, the staff can wait for a while and then press the lifting plate until the block on the outer wall of the lifting plate is stuck in the groove on the inside of the drain hole.

The interior of the filter housing is connected to the interior of the placement box through the plurality of through holes, and the water in the two will also circulate with each other. The water after flushing the surface of the fragrance block and the water stored in the filter housing are mixed and stirred by the rotation of the plurality of fan blades. They are evenly mixed with each other, so that the water used for showering has a refreshing effect. The staff can make the shower water have the effects of fragrance, mosquito repellent, skin cleaning and skin care according to the types and quantities of shower products placed in the placement box. There is no need to stop the water for manual application on the skin surface when the staff is showering, which is more convenient to use. When in use, the staff can place fragrance blocks of different sizes inside the placement box according to the daily shower time. After the shower is specified for a specified time, the placed fragrance blocks will be automatically exhausted, and the staff can complete the shower by a short period of continuous showering after the fragrance blocks are exhausted.

[0018] In the present invention, the staff can rotate the first fixing ring and the second fixing ring so that the second water delivery holes on the top of the first fixing ring and the second fixing ring are staggered with the first water delivery hole on the bottom of the fixed shell, so that the water inside the fixed shell cannot be transported to the multiple nozzles through the second water delivery holes. Instead, the staff can use the water outlet head to transport the water inside the fixed shell to the outside of the shell through the water outlet pipe and the water outlet head to form a water column, so that the limit column and the water outlet head cooperate with each other to achieve the function of a faucet. When in use, the faucet and the shower head are combined with each other. The staff can replace the nozzle and the water outlet head according to water demand, or use the nozzle and the water outlet head at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As a technical optimization solution of the present invention, several nozzles 4 are installed on the first fixing ring 5, the second fixing ring 6 and the bottom of the shell 1 near the edge, and the several nozzles 4 on the first fixing ring 5 and the second fixing ring 6 are respectively communicated with the inner cavity of the first fixing ring 5 and the second fixing ring 6, and several first connecting blocks 18 are installed on the inner bottom of the shell 1 near the inner wall, and the first connecting blocks 18 are communicated with the several nozzles 4 at the bottom of the shell 1; when in use, the first fixing ring 5, the second fixing ring 6 and the inner wall of the fixing hole 3 are interconnected and supported by the slider 25.

[0030] As a technical optimization solution of the present invention, several second connecting blocks 20 are installed on the outer wall of the fixed shell 16, one end of the second connecting block 20 is communicated with the first water supply hole 17 at the bottom of the fixed shell 16, and the other end of the second connecting block 20 is communicated with the first connecting block 18 through a hose 19. A first groove 10 is provided on the side of the lifting plate 9 away from the fixed shell 16; when the filtered water enters the interior of the first fixed ring 5 and the second fixed ring 6 through the first water supply hole 17, it can also be discharged from the shell 1 through the hose 19 and the nozzle 4 at the bottom of the shell 1.

[0031] As a technical optimization solution of the present invention, a limiting column 7 is rotatably installed inside the second fixed ring 6, and a second groove 14 is opened at the bottom of the limiting column 7. A water outlet head 13 is installed at the inner top of the second groove 14, and a water outlet pipe 12 is installed on the top of the water outlet head 13. The top of the water outlet pipe 12 passes through the limiting column 7 and is interconnected with the interior of the fixed shell 16. The top of the limiting column 7 is installed at the bottom of the fixed shell 16, and a switch valve is provided on the side of the bottom end of the water outlet head 13; when in use, the filtered water can flow out of the shell 1 through the water outlet pipe 12 and the water outlet head 13, so that the shell 1 can be used as a faucet when in use, and when in use, the staff can rotate the first fixed ring 5 and the second fixed ring 6 to stagger the second water supply hole 21 and the first water supply hole 17 thereon, thereby disconnecting the second water supply hole 21 from the water supply.

[0032] As a technical optimization solution of the present invention, an external threaded sleeve 11 is installed on the outer wall of the shell 1 at one end close to the water inlet hole 24, and a support tube 2 is threadedly installed on the outer wall of the external threaded sleeve 11. A connecting plate 22 is installed on the inner wall of the shell 1 at one end close to the external threaded sleeve 11. One side of the connecting plate 22 is interconnected with the interior of the external threaded sleeve 11, and the other side of the connecting plate 22 is connected to the water inlet hole 24 through a connecting tube 23; when in use, the end of the support tube 2 away from the shell 1 is connected to the external water pipe, so that the external water enters the interior of the filter shell 35 through the support tube 2, the external threaded sleeve 11, the connecting plate 22, and the connecting tube 23.

[0033] When the present invention is in use, the end of the support tube 2 away from the housing 1 is connected to the external water pipe, so that the shower water can be transported to the interior of the housing 1 through the water pipe and the support tube 2. When the staff needs to take a shower, the staff can pull the top side of the lifting plate 9 to move the lifting plate 9 out of the drain hole 8, and place a specified volume of fragrance blocks or bath salt blocks in the placement box 27 through the placement hole 30 according to the usage and shower duration, or place fragrance blocks and bath salt blocks in the placement box 27 at the same time, and press the lifting plate 9 after placement to move the lifting plate 9 to the interior of the drain hole 8 again. At the same time, several blocking blocks 38 located on the outer wall of the lifting plate 9 are stuck in the inside of the blocking groove 15 on the inner wall of the drain hole 8. When in use, the blocking groove 15 can play a better position limiting role for the lifting plate 9 through the blocking blocks 38, preventing the lifting plate 9 from being arbitrarily moved out of the drain hole 8 during showering.

[0034] When the staff takes a shower, the water entering the housing 1 can be transported to the inside of the filter housing 35 through the connecting plate 22, the connecting pipe 23 and the water inlet 24, and stored briefly inside the filter housing 35. When the water is transported to the inside of the filter housing 35, it will push the plurality of fan blades 32 inside the filter housing 35, so that the plurality of fan blades 32 drive the mounting sleeve 31 to rotate on the outer wall of the fixed shaft 28 under the push of the water flow. At the same time, when the plurality of fan blades 32 rotate, the water stored inside the filter housing 35 can also be mixed and stirred. Under the stirring of the fan blades 32, the water inside the filter housing 35 will enter the inside of the placement box 27 through the through holes on the outer wall of the placement box 27, and flush the surface of the fragrance block placed inside the placement box 27, and then pass through the placement box again. The through holes on the outer wall of the shower box 27 flow into the interior of the filter housing 35. During use, the interior of the filter housing 35 is interconnected with the interior of the storage box 27 through several through holes, and the water inside the two will also circulate with each other. The water after flushing the surface of the fragrance block and the water stored in the filter housing 35 are evenly mixed by the rotation of the several fan blades 32, making the shower water have a fragrance effect. The staff can adjust the shower water to achieve the effects of fragrance, mosquito repellent, skin cleansing and skin care according to the type and quantity of shower products placed in the storage box 27. The staff does not need to stop the water supply to manually apply the water to the skin surface during the shower, which is more convenient. During use, the staff can place fragrance blocks of different sizes in the storage box 27 according to the length of their daily shower. After the specified shower time, the placed fragrance blocks will automatically be exhausted. After the fragrance blocks are exhausted, the staff can continue to shower for a short time to complete the shower.

[0035] During use, a worker rotates the first and second fixing rings 5, 6, so that the second water transfer holes 21 on the first and second fixing rings 5, 6 communicate with the first water transfer hole 17 on the bottom of the fixed housing 16. Water within the filter housing 35 is filtered through the filter holes on its bottom before being transferred to the bottom of the fixed housing 16. There, it enters the inner cavities of the first and second fixing rings 5, 6 through the first and second water transfer holes 17, 21. The water inside the first and second fixing rings 5, 6 is then sprayed out of the housing 1 through the nozzles 4 on their bottoms. During use, the first water transfer hole 17 not only communicates with the inner cavities of the first and second fixing rings 5, 6, but also connects via the second connecting block 20, the hose 19, the first connecting block 18, and the nozzles 4 on the bottom of the housing 1. Therefore, during use, the first water transfer hole 17 can simultaneously supply water to the first and second fixing rings 5, 6, and the nozzles 4 on the bottom of the housing 1.

[0036] During use, the staff can rotate the first fixing ring 5 and the second fixing ring 6 so that the second water delivery holes 21 on the top of the first fixing ring 5 and the second fixing ring 6 are staggered with the first water delivery hole 17 at the bottom of the fixed shell 16, so that the water inside the fixed shell 16 cannot be transported to the multiple nozzles 4 through the second water delivery holes 21. Instead, the staff can use the water outlet head 13 to transport the water inside the fixed shell 16 through the water outlet pipe 12 and the water outlet head 13 to the outside of the shell 1 to form a water column, so that the limit column 7 and the water outlet head 13 cooperate with each other to achieve the function of a faucet. When in use, the faucet and the shower head are combined with each other. The staff can replace the nozzle 4 and the water outlet head 13 according to water demand, or use the nozzle 4 and the water outlet head 13 at the same time. When in use, the first fixing ring 6 is rotatably mounted on the inner wall of the fixing hole 3 through the slider 25, the second fixing ring 5 is rotatably mounted on the inner wall of the first fixing ring 6 through the slider 25, and the second fixing ring 5 is rotatably mounted on the outer wall of the limiting column 7, and the top of the limiting column 7 is mounted on the bottom of the fixing shell 16. When in use, the fixing shell 16, the limiting column 7, the first fixing ring 5, the second fixing ring 6 and the shell 1 are connected and supported to each other, so that the first fixing ring 5 and the second fixing ring 6 are more stable when in use.

[0037] When the water inside the filter shell 35 enters the interior of the fixed shell 16 through the filter holes at the bottom thereof, impurities in the water will remain inside the filter shell 35 through the filter holes at the bottom of the filter shell 35, preventing the impurities from clogging a single or multiple nozzles 4 during use. At the same time, when the filter holes at the bottom of the filter shell 35 are partially blocked during use, the remaining unblocked filter holes can still transport and filter the water inside the filter shell 35, so that the water is transported to the inner bottom of the fixed shell 16 through the remaining unblocked filter holes after being filtered, and will not affect the water spraying of several nozzles 4.

[0038] When most of the filter holes at the bottom of the filter housing 35 are clogged, the amount of water inside the filter housing 35 transported to the inside of the fixed housing 16 decreases. As the water inside the filter housing 35 gradually increases, the water pressure inside the filter housing 35 pushes the lifting plate 9 to move away from the bottom of the fixed housing 16 until the block 38 on the outer wall of the lifting plate 9 moves out of the slot 15. At the same time, the lifting plate 9 is quickly moved out of the drainage hole 8 by the push of the water pressure. At the same time, the limiting plate 34 on the lifting plate 9 slides inside the cleaning hole 33 on the inner wall of the filter housing 35 when the lifting plate 9 moves, and the bottom end of the L-shaped limiting plate 34 drives the filter housing 35 to move to a position away from the bottom of the fixed housing 16 by pulling the top of the cleaning hole 33, thereby increasing the space between the inner bottom of the filter housing 35 and the inner bottom of the fixed housing 16.

[0039] In use, the connecting pipe 23 is connected to the inside of the filter shell 35 through the water inlet hole 24 and the communication hole 29 on the inner wall of the filter shell 35. When the filter shell 35 moves, the communication hole 29 on the filter shell 35 also moves, and the guide block 37 moves in the guide groove 36, and the water inlet hole 24 is between the bottom of the filter shell 35 and the bottom of the fixed shell 16, and water is supplied to the space between the bottom of the filter shell 35 and the bottom of the fixed shell 16, and the water is supplied to the first water inlet hole 17 and the filter hole on the bottom of the filter shell 35. When the impurities in the shell 1 are cleaned, the spray head 4 can still spray water, but the water volume and spray intensity are reduced, which can remind the staff in the shower, and after the impurities in the shell 1 are cleaned, the staff can install the lifting plate 9 in time.

[0040] The water between the bottom of the filter shell 35 and the bottom of the fixed shell 16 enters the inside of the filter shell 35 through the filter hole on the bottom of the filter shell 35, and the filter hole is washed, so that the impurities in the filter hole flow into the inside of the filter shell 35 again, and flow to the direction of the lifting plate 9 in the inside of the filter shell 35, until it flows to the outside ground through the cleaning hole 33 on the inner wall of the filter shell 35, and carries the impurities in the inside of the filter shell 35 during the flow. After the staff is reminded by the reduced water volume of the spray head 4, the staff can press the lifting plate 9 after waiting for a period of time, so that the lifting plate 9 drives the filter shell 35 to move to the inside of the fixed shell 16, until the clamping block 38 on the outer wall of the lifting plate 9 is clamped in the clamping groove 15 on the inside of the drain hole 8. In use, the position of the lifting plate 9 and the filter shell 35 is fixed again, and the water inlet hole 24 is connected to the inside of the filter shell 35 through the communication hole 29, so that the connecting pipe 23 supplies water to the inside of the filter shell 35 again.

[0041] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
