[0002] With the development of technology and the improvement of people's living standards, water purifiers have gained recognition and achieved widespread use and application due to their advantages, namely the ability to purify domestic water, increase its purity level and thus provide healthier domestic water for users.

[0003] As disclosed in the utility model patent with Chinese patent number CN202021191564.5, which describes a filter cartridge assembly and a water purifier, the filter cartridge assembly comprises a filter cartridge and a plurality of filter cartridges. A plurality of receiving chambers are defined in the filter cartridge, which are connected to each other, and at least two of which are connected in parallel. The filter cartridge includes a water inlet port and a water outlet port, wherein the water inlet port is connected to the uppermost portion of any receiving chamber, and the water outlet port is also connected to the uppermost portion of any receiving chamber. The plurality of filter cartridges are arranged in the plurality of receiving chambers.By defining multiple receiving chambers for accommodating the filter cartridges in the filter cartridge of the above-mentioned filter insert assembly, connecting the receiving chambers to each other, and connecting at least two of them in parallel, the filtration efficiency for tap water in the receiving chambers can be increased. Furthermore, arranging the water inlet and outlet connections of the filter cartridge at the uppermost area of any receiving chamber enables a more compact design of the filter insert assembly. However, the filter insert assembly described above does not allow switching the parallel-connected filter inserts between filter operation and backwash operation, which results in limited flexibility and cannot meet user requirements.

Many specific details are described in the following description to facilitate a complete understanding of the present utility model. However, the present utility model can be embodied in many other ways other than the embodiments described herein, and those skilled in the art can make similar improvements without departing from the gist of the present utility model, so the present utility model is not limited to the specific embodiments disclosed below.

[0027] The present utility model will be discussed in more detail below with reference to the accompanying drawings and the exemplary embodiments.

[0028] It will be Fig.1 to 7. The structure with multiple interconnected filter cartridges comprises filter cartridges and a water pipe plate 1. The filter cartridges are provided in multiples. The water pipe plate 1 is provided with filter cartridge mounting positions 2 assigned to the multiple filter cartridges. A rotating base 3 is provided at each filter cartridge mounting position 2. Furthermore, a raw water channel 1.1, a clean water channel 1.2, and a wastewater channel 1.3 are arranged side by side on the water pipe plate 1.

The raw water channel 1.1 is connected to a first solenoid valve A1 and a third solenoid valve A3. The wastewater channel 1.3 is connected to a second solenoid valve A2 and a fourth solenoid valve A4.

[0029] In the present utility model, multiple filter inserts can be rotatably mounted at the respective filter insert mounting positions 2 via the respective rotating bases 3, thereby facilitating the installation and removal of the filter inserts. After installation, the multiple filter inserts can be connected in parallel to the raw water channel 1.1, the clean water channel 1.2, and the wastewater channel 1.3. Additionally, a first solenoid valve A1 and a third solenoid valve A3 are connected to the raw water channel 1.1, and a second solenoid valve A2 and a fourth solenoid valve A4 are connected to the wastewater channel 1.3.

This not only improves water utilization efficiency but also ensures the cleanliness of the filter cartridges. Furthermore, replacing individual filter cartridges prevents the water purification operation of other cartridges from being affected, allowing the water purifier to alternately realize water purification and self-cleaning of multiple filter cartridges. This significantly improves the water purification efficiency of the water purifier, the cleaning efficiency of the filter cartridges, and the application flexibility.At the same time, the durability, longevity and water filtration effect of the filter cartridges in the water purifier are ensured, which avoids the disadvantages of frequent filter cartridge changes and thus improves the user experience.
