Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a pre-filter structure and a water purifier. Background Technology

[0002] A water purifier is a household water treatment device whose main purpose is to remove impurities and harmful substances from water through physical or chemical means, providing safer and healthier drinking water.

[0003] The structure of a pre-filter water purifier is relatively simple, mainly consisting of the following parts:

[0004] Filter bottle: This is the outer shell of the pre-filter water purifier, usually made of stainless steel, copper, or plastic, which serves to protect the internal components and provide a seal.

[0005] Filter screen: Stainless steel filter screen: The most common filter medium, made of woven stainless steel wire, with a pore size usually between 40 microns and 100 microns, which can effectively intercept mud, rust, suspended particles, etc.

[0006] PP cotton filter: Made of polypropylene material, it has smaller pores and can filter finer particles.

[0007] Drain valve: Used to discharge impurities accumulated after filtration. It is usually a manual knob or an automatic control system, which is convenient for users to clean regularly.

[0008] Inlet and outlet water interfaces: These are the interfaces that connect to the household water supply pipes, and typically include an inlet and an outlet.

[0009] Pressure gauge: Some models of pre-filters are equipped with a pressure gauge to monitor water pressure and ensure that the water pressure is within the appropriate range.

[0010] Check valve: Prevents water backflow and protects water purifiers and household water pipes.

[0011] Controller: In some pre-filters with automatic flushing, the controller is used to start the flushing program automatically at set times or according to usage.

[0012] Scraper: Some pre-filters are equipped with a scraper to remove impurities attached to the filter screen, improving cleaning efficiency.

[0013] Transparent casing: Some pre-filters have transparent casings, allowing users to directly see the filter elements and accumulated impurities.

[0014] Existing pre-filters use PC material as the main filter element, with the filter element being a PP+carbon fiber composite filter. This filter structure can only remove larger particles of impurities and cannot remove metal ions or organic pollutants (such as bacteria and algae). Furthermore, the PP+carbon fiber composite filter element in existing technology is prone to mineral scaling, which leads to component contamination and scaling, significantly reducing the lifespan of the water purification system. Utility Model Content

[0015] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0016] The technical problem to be solved by this utility model is to provide a pre-filter structure and water purifier that can reduce mineral scaling, filter out metal ions and organic pollutants in raw water, and avoid filter cartridge contamination and scaling that reduce the life of the water purification system.

[0017] To solve the above-mentioned technical problems, the pre-filter structure of the water purifier provided by this utility model includes:

[0018] The bottle body has an inlet and an outlet formed at its top;

[0019] The water inlet is formed on one side of the upper part of the bottle body. One side of the inlet is connected to the raw water end, and the other side is connected to the first filter layer 4. The first filter layer is formed of Kedefei material.

[0020] The water outlet is located at the center of the upper part of the bottle, with one side connected to the clean water end and the other side connected to the central water channel;

[0021] The central water channel is formed at the center of the third filter layer, which is located at the geometric center of the bottle body.

[0022] The second filter layer is formed between the second filter layer and the third filter layer;

[0023] The third filter layer is formed inside the second filter layer;

[0024] The raw water enters through the inlet and can only pass through the first filter layer, the second filter layer, and the third filter layer in sequence to reach the central water channel before flowing out through the outlet.

[0025] KDF typically refers to a water treatment medium, which is a high-purity copper / zinc alloy particle. This material works through an electrochemical oxidation-reduction reaction (Redox). When in contact with water, the two metals in the alloy form countless tiny galvanic cell systems at the submicroscopic scale. This material has a strong reactivity and extremely fast reaction rate in water, and can remove up to 99% of chlorine and dissolved metal ions and compounds such as lead, mercury, nickel, and chromium from water.

[0026] Preferably, the pre-filter structure of the water purifier is further improved by including:

[0027] The upper fixing component is formed around the water outlet on the inner wall of the top of the bottle;

[0028] The lower fixing member forms the inner wall of the bottom of the bottle and is aligned with the upper fixing member in the vertical direction;

[0029] The second and third filter layers are arranged between the upper and lower fixing components.

[0030] Preferably, the pre-filter structure of the water purifier is further improved.

[0031] The upper fixing member is formed as an inverted bowl shape with a first vertical blocking part on the edge of the bowl;

[0032] The second vertical blocking part is formed at the geometric center of the upper fixing part;

[0033] The outlet is formed at the geometric center of the second vertical barrier.

[0034] The upper ends of the second and third filter layers are sandwiched between the first and second vertical blocking parts.

[0035] Preferably, the pre-filter structure of the water purifier is further improved, and the lower fixing member is formed into a bowl shape with a third vertical blocking part on the edge of the bowl;

[0036] The fourth vertical blocking part is formed at the geometric center of the lower fixing member;

[0037] The outlet is formed at the geometric center of the second vertical barrier.

[0038] The lower ends of the second and third filter layers are sandwiched between the third and fourth vertical blocking parts.

[0039] Preferably, in a further improvement to the pre-filter structure, the second filter layer is a PP cotton filter. PP cotton filter, also known as a polypropylene melt-blown filter, is a common water filtration material. It is made by heating and melting polypropylene particles, then spinning, drawing, and forming them into a tubular filter element.

[0040] Preferably, the pre-filter structure of the water purifier is further improved, and the third filter layer is a carbon fiber filter.

[0041] Carbon fiber filter cartridges (ACF) are high-performance filter media, a composite depth filtration material composed of cellulose and activated carbon powder. These cartridges possess the adsorption properties of activated carbon while also having the softness and processability of textile fibers.

[0042] Preferably, the pre-filter structure of the water purifier is further improved, and the bottle body is made of FRP material.

[0043] FRP (Fiber Reinforced Polymer) is a lightweight, high-strength material made by combining glass fiber, carbon fiber, aramid fiber, or other reinforcing materials with a matrix material such as resin. Due to its excellent physical and chemical properties, FRP materials have been widely used in many fields.

[0044] To solve the above-mentioned technical problems, the present invention provides a water purifier whose filtration structure is the pre-filter filtration structure described in any one of the above-mentioned claims.

[0045] This utility model can achieve at least the following technical effects:

[0046] 1) The bottle body abandons stainless steel, copper or plastic and adopts FRP material, which increases the durability of the pre-filter structure.

[0047] 2) This utility model adds KDF as a filter layer, which can reduce mineral scaling and protect the components of the water purifier from pollution and scaling, greatly extending the life of the water purification system and reducing system maintenance costs. Attached Figure Description
