Nozzle and water purifier with same

Abstract

The invention relates to a nozzle which is provided with a body and a head. An inner runner of the nozzle extends to the head from the body, the head is provided with an axial outflow passage and a lateral outflow passage, and the sectional area of the inner runner is suddenly decreased near the junction of the body and the head. According to the nozzle, the outflow velocity of all the outflow passages of the head can be increased, when the nozzle is applied to a water purifier, the scouring action on membrane wires can be enhanced, and adhesion of dirt on the membrane wires is reduced. The invention further relates to the water purifier which is provided with the nozzle.

Description

technical field [0001] The invention relates to a nozzle. The invention also relates to a water purifier with the nozzle. Background technique [0002] Water purifiers are more and more valued by consumers, and they are entering family and public places with rapid growth. The working principle of the water purifier is usually as follows: figure 1 As shown, the water purifier includes a water inlet 1, a water outlet 2, a casing 3 and a sewage outlet 7. The inner side of the water inlet 1 is provided with a nozzle 5, the inner side of the water outlet 2 is provided with a cavity 6, and the inner side of the housing 3 is also provided with a A series of membrane filaments 4 arranged in the circumferential direction, wherein the raw water enters from the water inlet 1 and is diverted when passing through the nozzle 5, a part of the water is sprayed from the round hole directly in front of the nozzle 5, and the other part of the water flows along the multiple holes on the side ...

AI Technical Summary

Problems solved by technology

However, in the prior art, the above-mentioned scouring effect is not obvious, mainly because the structure of the nozzle is not reasonable enough

Therefore, after running for a period of time, the water purifier of the prior art still has obvious efficiency decline, thus has to be disassembled for maintenance

[0004] The common structure of the water purifier nozzle of prior art is as Figure 2-5 As shown, the inner channel of the nozzle extends continuously from the body (the cross-sectional area transitions smoothly) to the head, and its six lateral slits are directly provided on the side wall of the nozzle, and the width of each slit remains constant. This structure leads to low turbulence intensity between the raw water ejected laterally and the raw water ejected axially, so the scouring and vibration effects on the membrane filaments are not obvious enough, and the sediment and dirt on the membrane filaments cannot be effectively removed, which ultimately reduces the The osmotic absorption of the membrane filament is reduced, which in turn affects the flow rate and long-term efficient operation of the water purifier
