Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a membrane component for a household water purifier. Background Technology

[0002] In recent years, with increasing attention to drinking water safety, the use of household water purifiers has gradually increased. Among them, filter cartridges containing separation membranes such as ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes are widely used. However, due to membrane fouling leading to filter cartridge clogging, water quality degradation, and low water output, frequent filter cartridge cleaning and replacement are necessary, resulting in inconvenience and increased costs.

[0003] The existing patent publication number is CN209522623U, which discloses a membrane module for a household water purifier, including a transparent filter cartridge shell, a hollow fiber nanofiltration membrane, an energy-saving lamp, an energy-saving lamp holder, and a membrane module shell. The hollow fiber nanofiltration membrane is disposed inside the transparent filter cartridge shell, which has an upper base at its upper end and a lower base at its lower end. The membrane module shell is disposed outside the transparent filter cartridge shell, and a cavity exists between the membrane module shell and the transparent filter cartridge shell. An energy-saving lamp holder is disposed within this cavity, and the energy-saving lamp is fixed in place by the holder. The hollow fiber nanofiltration membrane is a KBN-TiO2 / HBPA hollow fiber nanofiltration membrane. This invention features stable performance, strong resistance to fouling, a longer effective service life than general membrane modules, and high-quality effluent. However, during use, water flows naturally through the filter cartridge, relying solely on water pressure and its own flow rate, resulting in a relatively slow flow speed, which affects usability. Furthermore, filter cartridge replacement is relatively inconvenient.

[0004] To address this, we have invented a membrane module for home water purifiers. Utility Model Content

[0005] In view of the problems existing in the above and / or existing membrane components for household water purifiers, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a membrane assembly for a household water purifier that can solve the aforementioned existing problems.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A membrane module for a household water purifier includes a water purification tank, a filtration and disinfection component installed inside the water purification tank, and a support platform. A connecting rod is fixedly installed on the outer side of the support platform, and the end of the connecting rod away from the support platform is fixedly connected to the inner wall of the water purification tank.

[0009] A stirring structure is installed at the top of the support platform;

[0010] The filtration and disinfection assembly includes a filter frame, which is cylindrical in shape. Filter holes are evenly distributed on the side walls of the filter frame, and a cavity is formed inside the filter frame, which is filled with a filter membrane.

[0011] The stirring structure includes:

[0012] Annular plate one and annular plate two are provided, and a stirring rod is installed between the annular plate one and annular plate two. The outer wall of the stirring rod is fixedly equipped with stirring blades. The annular plate one and annular plate two are sleeved on the outer wall of the disinfection lamp, but do not contact its outer wall.

[0013] Annular sleeves are fixedly installed at the bottom end of the first annular plate and the top end of the second annular plate. The outer wall of the annular sleeve at the bottom end of the first annular plate is rotatably connected to the top end of the support platform.

[0014] The outer wall of the annular plate is uniformly arrayed with teeth, one side of which is engaged with a gear. A motor is fixedly installed on one side of the inner wall of the support platform, and the output end of the motor is fixedly connected to the bottom end of the gear.

[0015] In a preferred embodiment of the membrane assembly for a household water purifier described in this utility model, a disinfection lamp is installed at the center of the top of the support platform.

[0016] As a preferred embodiment of the membrane assembly for a household water purifier described in this utility model, the top of the water tank is an open structure and is covered with a cap, and the top of the cap is connected to a water inlet pipe.

[0017] As a preferred embodiment of the membrane assembly for a household water purifier described in this utility model, an annular sleeve is fixedly installed at both the top and bottom of the filter frame. An external thread is provided on the outer side of the annular sleeve. An annular groove is provided at the top of the inner wall of the cover and at the top of the support platform. An internal thread is provided on the inner wall of the annular groove and is threadedly connected to the external thread on the outer wall of the annular sleeve.

[0018] Compared with existing technologies:

[0019] Water is transported to the filter frame through the inlet pipe. The motor drives the gear to rotate, and the gear meshes with the teeth distributed on the outer side of the annular plate, causing the annular plate to rotate. The annular plate then drives the stirring rod and the stirring blades fixed on the outer side of the stirring rod to rotate, stirring the liquid and causing it to be thrown outward, accelerating its passage through the filter frame and improving the treatment efficiency.
