Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a modular water purification device with a composite filter element. Background Technology

[0002] A water purifier is a device used to remove impurities, pollutants, and harmful substances from water. It improves water quality through technologies such as physical filtration, adsorption, reverse osmosis, or ultraviolet sterilization, bringing it up to safe drinking or general use standards. Common filter elements include activated carbon, PP cotton, and RO membranes, which effectively filter sediment, residual chlorine, heavy metals, bacteria, and other pollutants. Water purifiers are widely used in homes, businesses, and industries, providing clean and healthy drinking water, protecting human health, and extending the lifespan of water-using equipment.

[0003] A search revealed patent publication number CN204958562U, which discloses a water purification device. The device includes: a main support frame; a pumping device mounted on the main support frame, having a pumping end and an outlet end, the pumping end connected to a water source, and the outlet end connected to the water purification device; and a water purification device having an inlet and an outlet, wherein the inlet and outlet of the water purification device are connected. This technical solution offers the following advantages: water from various water sources, such as pools, buckets, or other containers, can be pumped to the water purification device, purified, and then dispensed from a tap to provide emergency purified water.

[0004] While existing technologies can achieve a certain degree of filter cartridge removal and installation in water purifiers, they suffer from drawbacks such as cumbersome filter cartridge replacement, short water flow paths, poor filtration effects, and inconvenient cleaning and maintenance, leading to waste. In view of this, we propose a modular water purification device with composite filter cartridges, which solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a modular water purification device with composite filter cartridges.

[0006] The technical solution of this utility model is as follows: A modular water purification device with composite filter element, comprising a body, a mounting column, a mounting frame and a chassis. The lower end of the body is provided with a base plate, the upper end of the base plate is provided with a mounting groove, the chassis is provided inside the mounting groove, a filter element is fixed at the upper end of the chassis, a slot is provided inside the filter element, a mounting frame is inserted into the slot, and a mounting column is fixed at the upper end of the mounting frame.

[0007] When using this device, the second filter element inside the mounting column is fixed to the mounting bracket. The mounting bracket can be separated from the mounting column and inserted into the groove, enabling modular connection of the mounting column, mounting bracket, and first filter element. Water enters from the inlet, passes over the top of the first filter element, and enters the second filter element. Then, water enters the connection port from the outlet at the bottom of the second filter element, connecting to the nozzle for direct water purification. This device allows for modular installation and connection of filter cartridges. When replacing, either the first or second filter element can be directly replaced. It has a simple design, reliable operation, and high practicality.

[0008] Preferably, a second filter element is fixed inside the mounting bracket, a threaded hole is provided at the upper end of the mounting bracket, and a screw is rotatably installed at the upper end of the mounting post. The screw is rotatably installed inside the threaded hole. The cooperation between the screw and the threaded hole ensures that the second filter element is installed firmly and avoids loosening caused by water flow impact.

[0009] Preferably, the inner wall of the slot has a groove, and the mounting bracket is inserted into the groove. The groove limits the insertion path of the mounting bracket, avoids misaligned installation, and improves assembly accuracy.

[0010] Preferably, a placement platform is provided on one side of the base plate, a nozzle is provided on one side of the machine body, and a base is fixed at the lower end of the base plate. The placement platform facilitates temporary storage of disassembled filter elements or tools, improving operational convenience; the base enhances the stability of the machine body and prevents it from tipping over during operation.

[0011] Preferably, the mounting groove has positioning holes arranged in a ring array inside, and two screws are inserted into the upper end of the chassis. The two screws are inserted into the positioning holes. The ring positioning holes enable flexible installation of the chassis at multiple angles to adapt to different space requirements.

[0012] Preferably, the mounting groove has a connection port inside, the bottom of the chassis has a water outlet, the water outlet is inserted into the connection port, and the mounting column has a water inlet on one side. The insertion design of the connection port and the water outlet simplifies the water circuit connection and reduces the risk of leakage.

[0013] Preferably, the mounting bracket is one centimeter higher than the top of filter element one, the density of filter element one is less than that of filter element two, and the design of the mounting bracket being higher than filter element one prevents unfiltered water from overflowing; filter element one is a low-density pre-filter for large particulate impurities.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model enables quick assembly and disassembly of filter element one, filter element two, and mounting column through the plug-in connection of the mounting bracket and slot, simplifying the replacement process and improving maintenance efficiency; the split structure reduces the overall replacement cost, and only the specific filter element needs to be replaced to restore filtration performance.

[0016] II. Based on the first beneficial effect, this device achieves rapid disassembly and independent replacement of filter cartridges through modular structural design (such as slots, threaded fixing, and grooved guidance), significantly reducing maintenance costs. The tiered filtration system (filter cartridge one and filter cartridge two) optimizes filtration efficiency, while detailed design features such as positioning holes and inlet / outlet layout improve sealing and stability. Overall, it balances practicality, reliability, and economy, making it suitable for water purification scenarios requiring frequent maintenance or with limited space.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
