Nozzles and water purifiers for water purification

Abstract

The invention discloses a nozzle for purifying water and a water purifier and relates to the field of household appliances for improving the osmotic absorption effect of membrane filaments. The nozzle for purifying water comprises an introduction part and a rotational flow part, wherein the introduction part and the rotational flow part are fixedly connected and mutually communicated. A fluid inlet is formed in the introduction part and a rotational flow channel for changing the flow direction of a fluid is arranged on the rotational flow part; and the fluid entering the introduction part passes through the rotational flow channel on the rotational flow part and then flows out. By adopting the technical scheme, the flow direction of the fluid flowing through the rotational flow channel changes by virtue of the rotational flow channel and the disturbance and the turbulence intensity of the fluid are increased, so that scouring and vibration to the membrane filaments are enhanced, dirt is hardly attached to the membrane filaments and the adhesion amount of silt and dirt on the membrane filament is reduced. Therefore, the osmotic absorption effect of the membrane filaments is enhanced, so that the flow of the water purifier and long-term efficient operation of the water purifier are further guaranteed.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a nozzle for water purification and a water purifier. Background technique [0002] The nozzle is an important part of the water purifier. Water flows in from the inlet of the water purifier and flows out through the nozzle. The outflowing water has a certain pressure, and after osmotic absorption by the membrane filament, it flows out from the outlet of the water purifier. Due to long-term operation, a large amount of sand and dirt will adhere to the membrane filament. [0003] figure 1 It is a schematic diagram of the nozzle structure of the water purifier in the prior art Figure 1 ; figure 2 It is a schematic diagram of the nozzle structure of the water purifier in the prior art Figure II . see figure 1 and figure 2 , the nozzle has a water inlet, a central water outlet and a water discharge that are arranged oppositely; the number of the water discharge is four...

AI Technical Summary

Problems solved by technology

[0004] The inventors have found that there are at least the following problems in the prior art: water is sprayed from the outlet of the nozzle, the washing vibration of the water flow to the membrane wire is not large, and dirt is easy to adhere to the membrane wire

Moreover, the sprayed water has little vibration to the membrane filaments, and cannot wash and vibrate the sediment and dirt attached to the membrane filaments well, which reduces the permeation and absorption effect of the membrane filaments, thereby affecting the flow rate of the water purifier. and long-term efficient operation
