[0002] With the improvement of people's awareness of healthy drinking water, the disinfection and filtration of drinking water have become an important part of daily life. At present, the treatment of household drinking water or barreled water is carried out through methods such as coarse filtration, fine filtration, and disinfection. Especially for the disinfection and filtration treatment of barreled drinking water, the requirements are becoming increasingly strict and more refined.

[0003] The utility model patent with the Chinese patent publication number CN213834878U discloses a device for facilitating the extraction, filtration, and purification of barreled water, including a mixing tank, a detachable filtration mechanism, etc., which is convenient for disassembling and installing the filter screen and is relatively convenient during disassembly and cleaning. However, when this device is in use, water is transported to the filter hopper through a conduit. After the water sprays out from the end of the conduit, it cannot disperse the water column around, resulting in the water column impacting the middle part of the filter screen, and it is difficult to utilize other parts of the filter screen. This causes the filter screen to need to be frequently replaced, with low utilization rate, which is not conducive to continuously filtering drinking water. Moreover, particulate impurities in the water will clog the filter screen, resulting in a reduction in the filtering efficiency of the filter screen. Summary of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1-5As shown in the figure, a drinking water disinfection and filtration device includes a mounting plate 5. A conveying mechanism 3 is provided on the front surface of the mounting plate 5. The conveying mechanism 3 includes: a water inlet pipe 8. The tail end of the water inlet pipe 8 is connected to a mounting pipe 31. The tail end of the mounting pipe 31 is connected to a contraction pipe 32. The tail end of the contraction pipe 32 is connected to a diffuser pipe 33. The end of the diffuser pipe 33 is connected to a tail nozzle 34. The bottom end of the tail nozzle 34 is connected to a filter pipe 36. A water pump 38 is provided at the bottom end of the filter pipe 36. The water inlet end of the water pump 38 is connected to a drainage pipe 37. The end of the drainage pipe 37 is connected to the bottom of the filter pipe 36 through a flange. The water outlet end of the water pump 38 is provided with a conveying pipe 9. The end of the conveying pipe 9 is connected to a disinfection pipe 11. A reverse osmosis filter 13 is provided below the disinfection pipe 11. A funnel 361 is provided inside the filter pipe 36. A number of holes are formed in the inner wall of the funnel 361. A buffer zone 362 is also provided inside the filter pipe 36 near the lower part of the funnel 361;

[0029] A connection cover 35 is fixed at the tail end of the tail nozzle 34. The connection cover 35 is used for screwing with the outer thread of the filter pipe 36 so that the filter pipe 36 and the tail nozzle 34 can be connected. A filter screen is laid and fixed on the surface of the funnel 361 in advance;

[0030] The water flow enters the contraction pipe 32 after passing through the mounting pipe 31. The water flow flows downward and converges through the contraction pipe 32. The outlet cross-section of the contraction pipe 32 becomes smaller, and the water flow is accelerated. After the water flow passes through the diffuser pipe 33, the water flow increases again. Finally, it sprays out from the tail nozzle 34. When the water flow velocity increases and sprays out from the tail nozzle 34, the jet region increases and the spraying range increases. The water can be sprayed onto the funnel 361 inside the filter pipe 36 over a large area. The impurities in the water are filtered out by the filter screen on the funnel 361. The water also enters the buffer zone 362 through the holes. Finally, the water is pumped by the water pump 38 and conveyed to the next stage;

[0031] It should be noted that the contraction pipe 32, the diffuser pipe 33 and the tail nozzle 34 are combined to form a de Laval nozzle. After the water flow passes through the de Laval nozzle, both the flow velocity and the spraying range are improved.

[0032] Among them, as Figure 4As shown in the figure, flange plates 311 are provided at both ends of the installation pipe 31. A crushing assembly is further provided inside the installation pipe 31. The crushing assembly includes a main shaft 314. A propeller 316 is fixed to the outside of the main shaft 314, and a cutting knife 315 is also fixed to the outside of the main shaft 314. Positioning disks 312 are provided at the bottom and top inside the installation pipe 31. Circular holes 313 are formed on the surfaces of the positioning disks 312. Bearings are fixed in the middle of both positioning disks 312. Both ends of the main shaft 314 respectively penetrate through the bushings of the two bearings. Water passes through the installation pipe 31, the water flow passes through the circular holes 313, and then impacts the propeller 316. The propeller 316 rotates and drives the main shaft 314 to rotate. During the rotation of the main shaft 314, the cutting knife 315 is driven to rotate. The potential energy of the water flow causes the propeller 316, the main shaft 314, and the cutting knife 315 to rotate at high speed. The cutting knife 315 can cut the particulate impurities in the water flow, thereby crushing the particulate impurities and having the effect of refining the impurities.

[0033] It should be noted that as shown in the figure, a connecting pipe 6 is connected to the tail end of the disinfection pipe 11. The extending end of the connecting pipe 6 is connected to the water inlet of the reverse osmosis filter 13. A water outlet pipe 12 is connected to the water outlet of the reverse osmosis filter 13. Water passes through the delivery pipe 9, then enters the disinfection pipe 11, then passes through the connecting pipe 6, and finally enters the reverse osmosis filter 13. Under the filtering action of the reverse osmosis filter 13, the quality of the water is improved.

[0034] As Figure 1 and Figure 2 As shown in the figure, an installation bin 4 is provided on one side of the installation plate 5. A through hole 1 is formed on one side of the top of the installation bin 4. A receiving hole is also formed on the surface of the installation plate 5, and a fan 10 is fixed in the receiving hole. An air hole 14 is formed on the rear surface of the installation bin 4. The installation bin 4 has the function of stably supporting the installation plate 5, improving the reliability of the installation plate 5. And after starting the fan 10, the fan 10 extracts air, and the air circulation is beneficial to the air circulation around the installation plate 5, avoiding the generation of peculiar smell. At the same time, it is also beneficial to the heat dissipation of the water pump 38.

[0035] Among them, as Figure 1 As shown in the figure, a cushion block 2 is fixed to the front surface of the installation plate 5. The installation pipe 31 is placed on the front surface of the cushion block 2. A support block 7 is also fixed to the front surface of the installation plate 5. The bottom end of the reverse osmosis filter 13 is placed on the top of the support block 7. The installation plate 5 is inclined, which is beneficial to providing a support for the conveying mechanism 3, the disinfection pipe 11, and the reverse osmosis filter 13, and improving the overall stability;

[0036] The spacer block 2 is a buffer support made of rubber, which is used to support the installation pipe 31 and the stability of the entire conveying mechanism 3, and prevent the conveying mechanism 3 from shaking caused by water flow during the process of water flowing through the conveying mechanism 3. The support block 7 is used to support the reverse osmosis filter 13 to keep it stable.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
