Description

Technical Field

[0001] This invention relates to the field of water purifier technology, specifically a visualized whole-house pre-filter water purifier. Background Technology

[0002] The internal purification structure of a water purifier plays a decisive role in water purification, and timely replacement and cleaning of the filter structure is essential. However, water quality varies in different regions. In areas with poor water quality, the filter structure may need to be replaced and cleaned more frequently, while in areas with better water quality, it may not need to be cleaned or replaced as often. Therefore, it is very important to be able to directly judge the condition of the filter structure.

[0003] Most existing whole-house pre-filters are closed-loop structures, preventing users from directly observing the internal filter cartridges and the water's contamination levels. This often leads to decreased filtration efficiency due to failure to clean or replace the filters in a timely manner. Furthermore, some water purifiers have fixed structures, making disassembly and cleaning complex and impacting maintenance efficiency. For example, the existing technology "CN220633758U" only offers some convenience in disassembly and cleaning, but it doesn't allow for a direct assessment of the purifier's filtration structure, let alone complete disassembly. Summary of the Invention

[0004] This invention proposes a visual whole-house pre-filter water purifier that allows for intuitive observation of the filtration structure, ensuring timely filter replacement. This solves the problem of water purifiers where the filter or raw water chamber cannot be directly observed. Applying this design allows users to more conveniently understand when to clean or replace the filter, ensuring the filtration effect and ease of use for the whole-house water supply.

[0005] The technical solution of the present invention is as follows:

[0006] A visual whole-house pre-filter water purifier includes a raw water chamber and a purified water chamber, which are separated by a filter layer. The raw water chamber is provided with a first water inlet, and the purified water chamber is provided with a purified water outlet. The shell of the raw water chamber is made of transparent material to facilitate observation of the internal state.

[0007] The working principle and beneficial effects of this invention are as follows:

[0008] This invention features a visual design. During normal use, raw water enters through the first inlet and collects in the raw water chamber. As the amount of water entering increases, the water pressure inside the raw water chamber increases. After passing through the filter layer, the water in the raw water chamber flows into the purified water chamber. The filtered water then flows out through the purified water outlet for the user. Because impurities, ions, particulate matter, and microorganisms in the raw water cannot pass through the filter layer, these impurities will accumulate in the raw water chamber, requiring regular cleaning. With this solution, since the shell of the raw water chamber is made of a transparent material, the user can directly observe the sediment within the raw water chamber. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Introduction to the Structure of a Water Purifier

[0023] As attached Figure 1As shown, a visual whole-house pre-filter water purifier includes a raw water chamber and a purified water chamber; an ultrafiltration layer is provided between the raw water chamber and the purified water chamber; the raw water chamber is provided with a first water inlet 3, and the purified water chamber is provided with a purified water outlet 4; the shell of the raw water chamber is made of transparent material.

[0024] The dual-chamber design, combined with an ultrafiltration layer, ensures strict separation between raw water and purified water, preventing cross-contamination. The ultrafiltration layer effectively intercepts impurities in the water, providing a fundamental guarantee for purified water quality. The clearly defined inlet and purified water channels make the water flow path clearer, reducing water flow turbulence, improving purified water delivery efficiency, and facilitating precise integration with whole-house water systems. The transparent casing allows users to visually assess the water quality and impurity accumulation within the raw water chamber, enabling them to monitor the filtration status without disassembly and facilitating timely maintenance.

[0025] As attached Figure 3 and 5 As shown, a filter element 7 is installed in the raw water chamber. The filter element is located on one side of the raw water chamber of the filter layer and is connected to the permeable part of the filter layer. The filter element is also connected to the permeable part of the ultrafiltration layer. When raw water enters the raw water chamber through the first inlet 3, the filter element can adsorb impurities in the raw water. After the raw water is treated by the filter element and the ultrafiltration membrane, it enters the purified water chamber, making the water treated by the water purifier cleaner and safer. The filter element can pre-treat the raw water, reduce the impurity load entering the ultrafiltration layer, extend the service life of the ultrafiltration layer, and improve the overall filtration effect.

[0026] As attached Figure 2 As shown, the raw water chamber is also provided with a drain outlet 6; the drain outlet can discharge the impurities and sewage accumulated in the raw water chamber in a timely manner, avoid the deposition of impurities in the raw water chamber and in the filter element, keep the inside of the chamber clean, and reduce the risk of filter element blockage.

[0027] The water purification chamber is equipped with a second water inlet 5; the second water inlet 5 can be connected to purified water to achieve backwashing of the equipment, or it can be connected without water to periodically drain the water purification chamber and provide convenience for cleaning the water purifier.

[0028] As attached Figure 3 As shown, a fixing ring is provided at the fixed connection between the raw water chamber and the purified water chamber. The upper part of the fixing ring is connected to the upper shell 1, and the upper shell 1 and the upper surface of the filter layer form the purified water chamber with the help of the fixing ring. The lower part of the fixing ring is connected to the lower shell 2-1, and the lower shell and the lower surface of the filter layer form the raw water chamber with the help of the fixing ring. The fixing ring connects the upper and lower shells for fixed connection, connecting the raw water chamber and the purified water chamber. At the same time, the fixing ring fixes the ultrafiltration layer and the filter element, separating the raw water chamber and the purified water chamber through the filter element and the ultrafiltration layer. The design of the fixing ring makes the connection between the upper and lower shells and the filter layer more stable, accurately forming two independent chambers, ensuring the stability and sealing of the chamber structure.

[0029] As attached Figure 6 As shown, the fixing ring has multiple slots inside. The upper insertion part of the filter layer and the corresponding filter element is matched with the slots of the fixing ring and inserted into the slots inside the fixing ring. The slot design makes the installation of the filter element and filter layer more convenient and the positioning more accurate. At the same time, it disperses the water flow pressure, improves the filtration efficiency, and allows individual filter elements to be replaced when damaged, reducing maintenance costs.

[0030] The bottom of the upper housing is fitted onto the top of the fixing ring, and a first sealing ring is provided at the connection between the fixing ring and the upper housing; the first sealing ring can enhance the sealing of the connection between the fixing ring and the upper housing, prevent water leakage, and ensure the sealing of the water purification chamber.

[0031] A second sealing ring is provided between the inner side of the contact point between the upper housing and the lower housing and the fixing ring; the second sealing ring further enhances the sealing effect at the connection between the upper and lower housings and the fixing ring, preventing raw water and purified water from seeping into each other and improving the overall sealing reliability of the equipment.

[0032] The bottom of the upper housing and the top of the lower housing each have outward-folding structures. The upper and lower housings are fixedly connected to these outward-folding structures using clamps. The combination of the outward-folding structures and clamps makes the upper and lower housings more securely fixed, and the installation and disassembly process is simple and convenient, facilitating internal maintenance and component replacement. If it is necessary to clean the raw water chamber, the lower housing can be directly disassembled by opening the clamps; the clamp design makes disassembly even easier.

[0033] The lower housing includes a middle section and a lower section. The connection between the middle section and the lower section is turned outwards. A clamp is fitted over the turned-out parts of the middle section and the lower section. The lower section is made of transparent material. The split lower housing design allows for easy disassembly of the lower section via clamp connection. The transparent lower section facilitates observation of the internal conditions and also makes it convenient to clean and maintain the original water chamber.

[0034] The clamp consists of a pair of semi-circular structures, with one end hinged and the other end connected by an adjusting bolt. This clamp structure is flexible in operation, and the tightness can be precisely controlled by adjusting the bolt to ensure the stability of the connection. It is also easy to disassemble, facilitating the installation and maintenance of the equipment.

[0035] The water purifier has a fixing mechanism on the outside of its casing; the fixing mechanism can securely install the water purifier on the wall or other locations, preventing the equipment from shaking or shifting due to water flow impact or external force, and ensuring the stability and safety of the equipment operation.
