Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a pre-filter of water-driven and manual integrated scraping type. Background Art

[0002] At present, the pre-filter cleaning methods on the market mainly include forward flushing, back flushing, siphon flushing, straight silicone scraping, straight brush scraping, etc. However, the filter mesh has a small aperture and high filtering accuracy requirements, and different types of filter cleaning methods have different problems.

[0003] The flushing intensity of the forward flushing pre-filter is very weak, and the filter element is easily blocked. Not only can smaller impurities not be flushed out, but they are embedded deeper and tighter in the filter element, eventually causing the filter to become blocked, requiring consumers to remove the filter for cleaning, which is time-consuming and labor-intensive.

[0004] The siphon type pre-filter has a complex product structure. The flow rate of general household pipes is small, and the siphon flushing is not ideal. If the water quality is relatively poor in an area, the impurities will be embedded deeper and tighter on the filter surface, eventually causing the filter to become blocked, making cleaning and maintenance very difficult.

[0005] The backwash type pre-filter has technical improvements compared to the above pre-filters. Generally, the flow and pressure of household pipes are small, and the water outlet pressure of the nozzle is low. When encountering intercepted objects blocked in the filter holes, it is difficult to flush them clean. In addition, the inner wall of the filter is contaminated with impurities, which is not easy to clean, causing secondary pollution and bringing trouble to users.

[0006] The straight silicone scraping type and straight brush scraping type pre-filters can better clean large particles of rust, mud, insect eggs and other impurities, but during rotary scraping, there is a certain degree of extrusion between the straight silicone or straight brush and the contact surface of the filter, causing fine particles and colloidal suspended matter to embed deeper and tighter into the filter, making cleaning and maintenance very difficult. Utility Model Content

[0007] The utility model aims to solve the above technical problems and provide a pre-filter with integrated water drive and manual scraping and washing. The utility model adopts water drive and manual scraping and washing to clean the surface of the filter. The water drive scraping and washing utilizes water flow to drive the rotating sleeve to rotate: the large particles of rust, sand, insect eggs and other impurities adsorbed on the surface of the filter are scraped and washed. The impurities rotate with the water flow and are affected by gravity. These impurities fall from top to bottom along with the water rotation and are deposited at the bottom of the bottle, and are thoroughly cleaned when the sewage is discharged; at the same time, the water drive scraping and washing will generate a spiral rotating water flow to stir the colloidal suspended matter , reducing its contact with the filter and avoiding adsorption on the filter surface. It falls from top to bottom along the spiral water column to the bottom of the bottle and is deposited, and is thoroughly cleaned when discharging sewage; manual scraping and washing is due to the fact that impurities are still adsorbed on the filter surface after water drive scraping and washing and are difficult to clean, or larger particles are stuck in the rotating sleeve and cannot rotate when the water drive function is missing. At that time, manual scraping and washing will remove large particles of impurities to facilitate the rotation of the rotating sleeve driven by water. The manual rotating component of this scheme has no contact with the water drive cleaning component, which greatly reduces the resistance of the rotating sleeve and truly realizes the function of rotating and scraping when water is passed.

Under the action of gravity, these impurities fall from top to bottom along the water rotation to the bottom of the bottle and are deposited, and are thoroughly cleaned when sewage is discharged; when the cleaning assembly is driven to rotate by the pipeline water flow, a spiral rotating water column is generated to stir the colloidal suspended matter, and the colloidal suspended matter falls from top to bottom along the spiral water column to the bottom of the filter bottle and is deposited, and is thoroughly cleaned when sewage is discharged, reducing its contact with the filter screen and avoiding adsorption on the surface of the filter element assembly.

[0013] Preferably, a rotating ring is provided on the rotating sleeve, and a plurality of outer plates are provided on the rotating ring. After the water flows through the partition, it flows down obliquely, and the outer plates are arranged obliquely to be vertical or nearly vertical to the partition.

[0014] Preferably, the rotating sleeve is provided with a plurality of inclined frames. The setting of the inclined frames facilitates the sedimentation of impurities along the inclined direction. The rotating sleeve is provided with a fourth protrusion, and the bottom of the filter element is provided with a second groove, and the fourth protrusion is inserted into the second groove.

After passing through the water inlet pipe and the first water inlet channel in sequence, the water passes through the second water inlet channel on the fixed ring. The inclined partition on the second water inlet channel tilts the direction of the water and then hits the outer plate on the rotating ring. The outer plate is forced to drive the rotating ring to rotate, and the rotation of the rotating ring drives the rotating sleeve to rotate. The rotation of the rotating sleeve drives the brush member to rotate and scrape the filter screen. After the water gradually increases, impurities settle at the bottom of the filter bottle. After the water enters the connecting member through the filter element assembly, it is discharged from the water outlet pipe.
