Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water purifiers, in particular to a kitchen water purifier with multiple outlet switching. BACKGROUND

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that purifies and filters water to meet water usage requirements. The water purifier commonly referred to is a small purifier for home use, which includes removing floating objects, heavy metals, bacteria, viruses, residual chlorine and other impurities in water, and is different from the water dispenser which focuses on water temperature adjustment. Water purification is achieved through multi-stage filtration systems such as microfiltration membranes, compressed carbon, and ultrafiltration membranes. The technical core of the water purifier is the filtration membrane in the filter cartridge device, and the main technology comes from ultrafiltration membranes, RO reverse osmosis membranes, and nanofiltration membranes. Most products use the principle of progressive structure of screen filtration, and some new products use the principle of self-cleaning structure of quality flow. The filtration system includes a life indicator that ensures water safety by calculating the total water volume. Water purifiers can be divided into two categories: progressive water purifiers and self-cleaning water purifiers, according to the design level of the pipeline. The traditional water purifier is a progressive water purifier, and its internal pipeline design is loose before the filter core and tight after it, with a PP melt-blown filter core, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. Generally, these five levels are connected in sequence. The retained material is deposited inside the filter core, which needs to be manually disassembled and washed regularly to ensure normal operation of the machine. The other type is a more advanced self-cleaning water purifier, which has two channels inside the machine, adding a washing water passage. The washing water, which is ordinary domestic water, flows through the passage and washes the membrane filter core on the raw water side, achieving self-cleaning. The retained material is quickly removed using the water that flows in and out of the two sections when the washing water faucet is opened and closed. This design is reasonable, eliminating the need for manual disassembly and washing, preventing the machine from being contaminated again, and reducing energy consumption and costs.

[0003] The existing kitchen water purifier has a filter core that is clogged during long-term use, resulting in a small amount of water being discharged from the water purifier and poor water quality being filtered and discharged. At this time, the filter core in the water purifier needs to be replaced. The filter core in the water purifier on the market is generally installed and disassembled using a press-out method or a screw fixation method. The spring ages over time, making the filter core installation not firm enough and prone to shaking. The screw fixation method is prone to loosening during the operation of the water purifier due to the vibration generated by the water purifier, which also makes the filter core installation not firm enough. In addition, the water flow speed between the existing filter core and filter cartridge is slow, making it easy for impurities in the water to adhere to the outer wall of the filter core, thereby affecting the water permeation filtration, water discharge speed, and filtration quality. Therefore, we provide a kitchen water purifier with multiple outlet switching to solve the above problems. SUMMARY

[0004] The kitchen water purifier of the present application can switch multiple water outlets, and the arc-shaped handle is controlled to expand or close, so that the arc-shaped handle drives the internal threaded pipe to rotate, and in turn drives the two screw rods to rotate, and at the same time, the screw rods move towards the direction of approaching or moving away from the partition plate, and in turn, the arc-shaped guide plate and the moving seat drive the clamping plate to move towards the direction of approaching or moving away from the partition plate, so that the clamping plate is separated from the arc-shaped groove or clamped in the arc-shaped groove, thereby achieving the disassembly or installation of the purification assembly. Compared with the traditional pop-up and screw fixing mode, the present application has better reliability and firmness. At the same time, the second magnet block is attracted to the first magnet block, thereby completing the locking of the arc-shaped handle, avoiding the expansion of the arc-shaped handle due to external scratching or touching, improving the firmness of the cylindrical pipe in the locked state of the cylindrical groove, and solving the problems of the existing kitchen water purifier, such as the clogging of the filter core in the water purifier during long-term use, the decrease of the water output of the water purifier, and the poor quality of the filtered water. At this time, it is necessary to replace the filter core in the water purifier. The filter core installation and disassembly of the water purifier on the market generally adopts the pop-up or screw fixing mode. The spring is aged after long-term use of the pop-up mode, so that the filter core is not installed firmly and is prone to shaking. The screw fixing mode is prone to loosening due to the vibration of the water purifier during the operation of the water purifier, and the filter core is also not installed firmly. In addition, the water flow speed between the existing filter core and filter cartridge is slow, so that the impurities in the water are easily attached to the outer wall of the filter core, thereby affecting the water permeation filtration, water output speed and filtration quality.
