Description

Technical Field

[0001] This utility model relates to the field of water purification device technology, specifically a water purification device for differentiating drinking water from domestic water supply. Background Technology

[0002] This water purification system, designed for separating drinking water and domestic water supply, is a highly efficient water treatment device. It aims to treat tap water or other water sources into two categories: directly drinkable water and non-drinkable water suitable for daily use. Through advanced technologies such as multi-stage filtration, reverse osmosis, and ultraviolet sterilization, the system removes impurities, bacteria, heavy metals, and other harmful substances from the water, ensuring that the drinking water meets safe drinking standards. Simultaneously, the system's diversion design allows a portion of the treated water to be used for domestic purposes such as washing and cleaning, conserving water resources while meeting diverse water needs. This system is widely used in homes, schools, office buildings, and other locations, providing users with a safe and convenient solution for differentiated water supply.

[0003] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: Traditional water purification devices directly purify water, but if there are many large particulate impurities in the water, it will increase the filtration burden of the water purification device and affect its filtration effect; therefore, in order to address the above problems, a water purification device for separate supply of drinking water and domestic water is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a water purification device for separate supply of drinking water and domestic water, which has the advantage of pre-filtration. It solves the problem that traditional water purification devices directly purify water, but if there are many large particles of impurities in the water, it will increase the filtration burden of the water purification device and affect its filtration effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water purification device for separate supply of drinking water and domestic water, comprising a supporting shell, an inlet pipe connected to the surface of the supporting shell, a pre-filter assembly provided at the end of the inlet pipe, a cleaning assembly provided on the surface of the pre-filter assembly, a filter cylinder provided at the top of the supporting shell, and a connecting pipe connecting the supporting shell and the filter cylinder.

[0006] The effect achieved by the above components is as follows: by setting up the cooperation between the pre-filtration component and the cleaning component, it can be used to perform preliminary filtration of water, prevent large particles of impurities in the water from affecting the filtration performance of the filter cartridge, and thus improve the filtration and purification effect of water.

[0007] Preferably, the pre-filtration assembly includes an installation frame that is connected to the water inlet pipe. The installation frame has a sealing groove inside, and a sliding plate is slidably installed inside the sealing groove. Two filter screens are provided on the surface of the sliding plate.

[0008] The above components achieve the following effects: They seal the connection between the external water pipe and the end of the inlet cylinder, guiding the water to be filtered into the interior of the supporting shell. As the water flows through the inlet cylinder, the flowing water drives the drive fan blades to rotate, which in turn drives the rotating shaft to rotate. This rotating shaft then drives the cleaning plate to rotate, cleaning the surface of the filter screen and removing impurities to prevent clogging. To replace the filter screen, rotate the positioning bolt, causing it to move upwards and disengage from the slot. The sliding plate can then slide inside the sealing groove, moving another filter screen into the groove. Finally, rotate the positioning bolt again, engaging its bottom into the slot, completing the filter screen replacement.

[0009] Preferably, a side plate is fixedly mounted on the surface of the mounting frame, a positioning bolt is threaded onto the surface of the side plate, and a slot for use with the positioning bolt is provided on the surface of the sliding plate.

[0010] The above components achieve the following effect: by setting the cooperation between the side plate, positioning bolt and slot, the sliding plate is limited, which improves the stability of the sliding plate during use and avoids the sliding plate from swaying left and right, which would cause the filter screen to be unstable and affect the filter screen's filtration performance.

[0011] Preferably, the side plate has a threaded hole on its surface, the positioning bolt passes through the threaded hole and is threadedly connected to the threaded hole, and the end of the positioning bolt is engaged in the inside of the slot.

[0012] Preferably, the cleaning assembly includes a water inlet cylinder, which is connected to the mounting frame. A connecting sleeve is connected to the end of the water inlet cylinder. A rotating shaft is rotatably connected inside the water inlet cylinder. Two drive fan blades are fixedly installed on the surface of the rotating shaft. A cleaning plate for cleaning the filter screen is fixedly installed at the end of the rotating shaft.

[0013] The effect achieved by the above components is as follows: under the action of water flow, the drive fan blades rotate, the drive fan blades drive the rotating shaft and cleaning plate, and then the cleaning plate cleans the filter screen, preventing large impurities from clogging the filter screen and affecting the filter screen's filtration performance.

[0014] Preferably, a mounting bearing is fixedly installed inside the water inlet cylinder, and the mounting bearing is sleeved on the surface of the rotating shaft.

[0015] The effect achieved by the above components is as follows: by setting up the mounting bearing for mounting and limiting the shaft, the stability of the shaft during rotation is improved, thereby improving the stability of the drive fan blades and cleaning plate during rotation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the cooperation between the pre-filtration component and the cleaning component, can be used for preliminary filtration of water, preventing large particles of impurities in the water from affecting the filtration performance of the filter cartridge, thereby improving the filtration and purification effect of the water. At the same time, it solves the problem that traditional water purification devices directly purify water, but if there are many large particles of impurities in the water, it will increase the filtration burden of the water purification device and affect its filtration effect.

[0025] The combination of the pre-filtration component 2 and the cleaning component 3 enables preliminary filtration of water, preventing large particles of impurities in the water from affecting the filtration performance of the filter cartridge 5, thereby improving the filtration and purification effect of the water.

[0026] Specifically, the primary filter assembly 2 includes an installation frame 201, which is connected to the water inlet pipe 4. A sealing groove 202 is provided inside the installation frame 201, and a sliding plate 203 is slidably installed inside the sealing groove 202. Two filter screens 204 are provided on the surface of the sliding plate 203.

[0027] Specifically, a side plate 205 is fixedly mounted on the surface of the mounting frame 201, and a positioning bolt 206 is threadedly connected to the surface of the side plate 205. A slot for use with the positioning bolt 206 is opened on the surface of the sliding plate 203.

[0028] The side plate 205, positioning bolt 206 and slot are designed to limit the sliding plate 203, improve the stability of the sliding plate 203 during use, and prevent the sliding plate 203 from wobbling left and right, which would cause the filter screen 204 to be unstable and affect the filtration performance of the filter screen 204.

[0029] Specifically, the side plate 205 has a threaded hole on its surface, the positioning bolt 206 passes through the threaded hole and is threadedly connected to the threaded hole, and the end of the positioning bolt 206 is engaged in the inside of the slot.

[0030] Specifically, the cleaning component 3 includes a water inlet cylinder 301, which is connected to the mounting frame 201. A docking sleeve 302 is connected to the end of the water inlet cylinder 301. A rotating shaft 303 is rotatably connected inside the water inlet cylinder 301. Two drive fan blades 304 are fixedly installed on the surface of the rotating shaft 303. A cleaning plate 305 for cleaning the filter screen 204 is fixedly installed at the end of the rotating shaft 303.

[0031] Under the action of water flow, the drive fan blade 304 rotates, which in turn drives the rotating shaft 303 and the cleaning plate 305. The cleaning plate 305 then cleans the filter screen 204 to prevent large impurities from clogging the filter screen 204 and affecting its filtration performance.

[0032] Specifically, an installation bearing is fixedly installed inside the water inlet cylinder 301, and the installation bearing is sleeved on the surface of the rotating shaft 303.

[0033] By setting up a mounting bearing for mounting and limiting the rotating shaft 303, the stability of the rotating shaft 303 during rotation is improved, thereby improving the stability of the drive fan blade 304 and cleaning plate 305 during rotation.

[0034] In use, the external water pipe is sealed to the end of the inlet cylinder 301, and the water to be filtered is introduced into the interior of the support shell 1. When the water passes through the interior of the inlet cylinder 301, the flowing water will drive the drive fan blade 304 to rotate. The drive fan blade 304 drives the rotating shaft 303 to rotate, and then the rotating shaft 303 drives the cleaning plate 305 to rotate. The rotating cleaning plate 305 cleans the surface of the filter screen 204, removing impurities attached to the surface of the filter screen 204 to prevent impurities from clogging the filter screen 204. When it is necessary to replace the filter screen 204, rotate the positioning bolt 206 so that the positioning bolt 206 moves upward and disengages from the inside of the slot. At this time, the sliding plate 203 can slide inside the sealing groove 202 to move another filter screen 204 into the inside of the sealing groove 202. Then rotate the positioning bolt 206 again so that its bottom is engaged inside the slot, completing the replacement of the filter screen 204.
