Description

Technical Field

[0001] The utility model relates to the technical field of water filtration, in particular to a flushing mechanism for a water purifier filter element. Background Art

[0002] Tap water is a very important urban water supply. With the popularization of tap water, it is also widely used in many rural areas. Generally speaking, tap water refers to the water that meets the national drinking water standards and is produced through purification and disinfection by a water treatment plant for people's living and production use. After being purified, disinfected and other treatments, tap water has to pass through a long pipeline before flowing out of the faucet. Therefore, there will also be some impurities remaining in the tap water flowing out of the faucet finally, such as rust, tiny particles, a small amount of bacteria, etc. in the tap water pipeline system. Moreover, the water sources of different water treatment plants are different and the treatment processes are different. The tap water from water treatment plants with backward treatment processes is very likely not to meet the standards. In order to further improve the safety of tap water use, it is necessary to flush the filter element of the water purifier to prevent the safety of the used water from decreasing due to dirt accumulation.

[0003] For example, the utility model with the application number 202021780255.1 discloses a household water purifier filter element cleaning device. Aiming at the problems that the existing filter element cleaning is all manual cleaning, the cleaning efficiency is low and the cleaning effect is poor, the following scheme is proposed. It includes a cleaning box, a cover plate is installed on the top of the cleaning box, a fixing cavity is opened on the cleaning box, a plurality of mounting holes are opened on one inner wall of the fixing cavity, and flushing nozzles are installed in the plurality of mounting holes. A water pump is fixedly installed on one side of the cleaning box, the water inlet pipe of the water pump is fixedly connected in the fixing cavity, a through hole is opened on the bottom inner wall of the cleaning box, a rotating column is rotatably installed in the through hole, a rotating plate is fixedly installed at the top of the rotating column, and a filter element is placed on the top of the rotating plate. The structure of the utility model is reasonable and the operation is convenient. The filter element cleaning device can automatically clean the filter element, with high cleaning efficiency and good cleaning effect.

[0004] Similar to the above application, there are still the following deficiencies at present. The above comparative document only uses the water pump to drive the water to spray through the through holes on the water inlet pipe to clean the filter element, and the cleaning method is very single. Sometimes there are a large number of insoluble impurities in the water, which will adhere to the outer wall of the water purifier filter element. When the water purifier is automatically cleaned, there may be a problem of water accumulation. The accumulated water will remain with impurities, bacteria and pollutants. At the same time, the sewage drainage structure in the water purifier cannot completely drain the accumulated water, which is easy to cause secondary pollution.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a flushing mechanism for a water purifier filter element is proposed. Summary of the Utility Model

Specific implementation manners

[0027] The following will combine with the attached Figures 1 to 8 The present utility model will be described in detail. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] The present utility model provides a water purifier filter element flushing mechanism through improvement. As Figures 1 - 5 shown, it is applied to the water purifier 15. The outer surface of the upper end of the water purifier 15 is provided with a water outlet head 16. Inside the water purifier 15, there is a base 1. A placing groove 2 is opened at the center position of the upper end of the base 1. The bottom of the placing groove 2 is movably connected with a filter element 3. A water inlet pipe 9 penetrates through the center position of the bottom of the placing groove 2. A plurality of water spraying holes are opened at the upper end of the water inlet pipe 9. The lower end of the water inlet pipe 9 is connected to the output end of a water pump 10. Locking grooves 6 are opened at the lower ends on the left and right sides of the filter element 3. A locking mechanism 5 is arranged at the position corresponding to the locking grooves 6 at the upper end of the base 1. The upper end of the base 1 is movably connected with a splash-proof shell 4. A motor 11 is fixedly installed at the upper end of the splash-proof shell 4. A cleaning mechanism is arranged at the lower end inside the splash-proof shell 4.

[0029] In this embodiment: First, the filter element 3 is located in the placement groove 2, and a splash-proof shell 4 is provided outside it to prevent sewage from splashing during cleaning. The water pump 10 can be used to make the cleaning water pass through the water inlet pipe 9 and clean the filter element 3 through the water spray nozzle. With the cleaning mechanism, the cleaning effect can be further improved. The sewage from the flushing will slide down along the inner wall of the filter element 3 into the placement groove 2 for storage and discharge, reducing the water accumulation at the filter element part and avoiding the influence of water accumulation on the normal water purification work, effectively reducing impurities, bacteria and pollutants in the filter element to ensure the provision of clean and healthy drinking water.

[0030] The following is a further supplement to the above solution: A number of water leakage holes are opened at the bottom of the placement groove 2, and a water storage tank 7 is fixedly installed at the lower end of the base 1. The sewage flows into the lower water storage tank 7 through the water leakage holes opened at the lower end of the placement groove 2 to collect the cleaned sewage, and can be discharged outside the water purifier through the sewage discharge pipe at the rear of the water storage tank 7. A plug 8 is riveted to the upper end of the left surface of the base 1, and the plug 8 penetrates through the outer walls of the base 1 and the splash-proof shell 4, so that the splash-proof shell 4 can be disassembled and installed for subsequent maintenance work.

[0031] In the above solution, there may be dirt adhering to the filter element 3, which is difficult to clean completely only by flushing with water and still remains on the filter element 3, resulting in insufficient overall cleaning of the filter element 3. In order to achieve the purpose of fully cleaning the filter element 3, the specific operation is as follows:

[0032] As Figure 1 and Figure 2 shown, a cleaning mechanism is provided at the lower end inside the splash-proof shell 4, including a rotating connecting rod 12 rotatably connected to the lower end of the motor 11. Rotating brushes 14 are rotatably connected to the left and right ends of the rotating connecting rod 12, and scraping plates 13 are fixedly connected to the front and rear ends of the rotating connecting rod 12.

[0033] In this embodiment: When flushing the filter element 3, the motor 11 can be started, so that the rotating connecting rod 12 connected to the lower end of the motor 11 rotates around the motor 11, and at the same time drives the rotating brushes 14 to roll on the inner wall of the filter element 3 and the scraping plates 13 to scrape on the outer wall of the filter element 3, so that the dirt that is difficult to wash off on the filter element 3 is cleaned by the rotating brushes 14 and the scraping plates 13, and the dirt cleaned will flow into the lower placement groove 2 along the rotating brushes 14 and the scraping plates 13.

[0034] In the above solution, the filter element 3 may shift or tilt during the flushing process, resulting in the water sprayed from the water spray nozzle being unable to clean the filter element 3 comprehensively, resulting in insufficient cleaning of the filter element 3. In order to achieve the purpose of no shift of the filter element 3 during the flushing process, the specific operation is as follows:

[0035] As Figure 3 and Figure 6As shown in the figure, a locking mechanism 5 is provided at the position corresponding to the upper end of the base 1 and the locking groove 6. The locking mechanism 5 includes an upper slider 51 that fits on the upper end of the base 1. An adjusting screw rod 53 is movably installed at the middle position of the upper end of the upper slider 51. A lower slider 52 is threadedly connected to the lower end of the adjusting screw rod 53. The adjusting screw rod 53 passes through the middle of the lower slider 52. The upper end of the adjusting screw rod 53 is fixedly connected to a knob 54.

[0036] As Figure 7 and Figure 8 shown in the figure, the upper end of the water inlet pipe 9 is connected to a delivery pipe 17. One end of the delivery pipe 17 is rotatably connected to the inner side of the rotating connecting rod 12. A flow passage communicating with the delivery pipe 17 is provided inside the rotating connecting rod 12. The flow passage inside the rotating connecting rod 12 is communicated with the inside of the brush roller 14. Nozzles 19 are provided on the outer wall of the brush roller 14. A cavity communicating with the inside of the rotating connecting rod 12 is provided inside the brush roller 14. A reciprocating transmission screw rod 20 and a positioning rod 22 are provided inside the cavity of the brush roller 14. One end of the reciprocating transmission screw rod 20 is rotatably connected to the inside of the rotating connecting rod 12. The other end of the reciprocating transmission screw rod 20 is connected to a fixed buckle 18. One end of the positioning rod 22 is fixedly connected to the inside of the rotating connecting rod 12. A film 21 is provided on the outside of the reciprocating transmission screw rod 20. The positioning rod 22 passes through the film 21.

[0037] While the brush roller 14 is rolling, the brush roller 14 and the fixed buckle 18 can drive the reciprocating transmission screw rod 20 to rotate. When the reciprocating transmission screw rod 20 rotates, it can drive the film 21 to move reciprocally. The film 21 can push the water inside the rotating connecting rod 12 into the inside of the brush roller 14. Then the water inside the brush roller 14 is sprayed out through the nozzles 19. The water sprayed out through the nozzles 19 can clean the filter element 3, which can improve the cleaning effect of the filter element 3. Moreover, the water inside the water inlet pipe 9 can enter the inside of the rotating connecting rod 12 through the delivery pipe 17 to supplement water to the inside of the rotating connecting rod 12. The positioning rod 22 plays a role in positioning the film 21 to prevent the film 21 from rotating automatically.

[0038] In this embodiment: The cleaner slides the upper slider 51 so that the upper slider 51 is inserted into the locking groove 6 and riveted to the locking groove 6 to fix the filter element 3. The cleaner can rotate the knob 54 to control the rotation of the adjusting screw rod 53 to adjust the pressure between the upper slider 51 and the lower slider 52 and the base 1, thereby fixing the upper slider 51 more firmly to make the fixing of the filter element 3 more secure.
