Abstract

A welding fixed structure of the inner shell of the shower head, which mainly comprises an inner shell, a self-clean water outlet net, a tight-pressing loop and a panel, the self-cleaning net and the tight-pressing loop are arranged between the inner shell and the panel, wherein the back part of the panel forms a plurality of convex feet, a cooperation hole is arranged corresponding to the convex feet on the inner shell, while the tight-pressing loop is arranged between the inner shell and the panel, each convex foot of the panel is arranged in an extended manner behind the cooperation hole of the inner shell and utilizes the hot melt to join the convex feet of the cooperation hole in fusion on the inner shell. A sealed space is formed by the interference fit of the inner shell and the self-clean water outlet net when the inner shell is pressed. The welding arrangement combining with the sealed structure overcomes the sealing and strengthening problems between different types of channels, which greatly reduces the production difficulty of the produces and improves the effectiveness of the structure, avoids the inner shell to appear the phenomenon of water leakage because of none-tight combination, improves the binding strength and binding quality of the inner shell of the shower head, makes the processing more simplified and easier to be implemented, and not only suitable for structure with large area but also suitable for structure with weird shapes.

Description

Shower nozzle inner housing welding fixed structure

Technical field

The utility model is about a kind of bath articles, is meant a kind of shower nozzle inner housing welding fixed structure especially.

Background technology

At present, the shower nozzle of bath articles no longer is confined to miniaturization, and it develops to the big direction of water-outlet area, thereby the volume of shower nozzle increases relatively to some extent, some difficulty of processing can appear in the process of the especially direction that area is big towards thickness is little, thereby this shower nozzle.As: its inner housing mostly is plastic parts, for guaranteeing under the situation that its thickness do not increase, the junction adopts the mode of ultrasonic fusing to connect more, and because the increasing of shower nozzle area makes hyperacoustic equipment can't satisfy the requirement of welding, in addition the restriction of special material, make this junction adopt ultrasonic fusing and can't satisfy being tightly connected of inner housing, thereby in use, under the effect of hydraulic pressure, the phenomenon of leaking withstand voltage deficiency can appear and in inner housing.

The utility model content

The purpose of this utility model is to provide a kind of shower nozzle inner housing welding fixed structure, its can make inner housing in conjunction with after the resistance to pressure height, seal good, thereby avoid inner housing drainage to occur.

For achieving the above object, technical solution of the present utility model is: a kind of shower nozzle inner housing welding fixed structure, it is mainly by inner housing, constitute from going out the network of rivers, compacting ring and panel clearly, from go out the network of rivers clearly, compacting ring places between inner housing and the panel, wherein be formed with several protruding pin in panel rear, corresponding this protruding pin is provided with mating holes on inner housing, and compacting ring is to place between inner housing and the panel, and the protruding pin of each of panel is to stretch the protruding pin that utilizes hot melt will stretch out mating holes behind the mating holes that places inner housing to be fused on the inner housing.

Described inner housing lower edge forms two circle ribs, is interference fit with going out the network of rivers clearly certainly.

After adopting such scheme, because the utility model is to be convexly equipped with some protruding pin at the panel back, cooperate mating holes corresponding on the inner housing, the two in conjunction with the time, the protruding pin of panel is to utilize hot melting way that protruding pin is fused on the inner housing again after stretching the mating holes that places inner housing, thereby realizes the combination between the two, form the inner housing runner, when pushing down inner housing, two on the inner housing encloses rib and goes out network of rivers interference fit certainly clearly, forms seal cavity.The utility model is to utilize this solid welding mode, in conjunction with this hermetically-sealed construction, overcomes sealing and strength problem between the shaped flow channel, reduces the manufacture difficulty of product and the validity of raising structure greatly.This kind structure can effectively avoid inner housing to occur in conjunction with not firm and phenomenon that occur leaking, thereby improves the bond strength and the bond quality of seedpod of the lotus inner housing, and easily row is simplified in order processing more; It not only is adapted to the big structure of area but also is more suitable for the strange structure of shape.

Description of drawings

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is a combination schematic diagram of the present utility model;

Fig. 3 is a sectional view of the present utility model.

The specific embodiment

As shown in Figure 1, 2, shower nozzle inner housing welding fixed structure of the present utility model, it comprises inner housing 1, constitutes from going out the network of rivers 2, compacting ring 3 and panel 4 clearly.

Inner housing 1 lower edge communicates with water inlet pipe, and forms a flow path groove, forms two circle ribs 12 at inner housing 1 lower edge simultaneously;

And moulding is distributed with

delivery port

21,31 on it with the compacting ring 3 corresponding above-mentioned runners of difference from going out the network of rivers 2 clearly, and the effect of the two is that current are evenly disperseed, make whole circle spray even, strong and weak consistent, wherein compacting ring 3 is made for soft materials, makes it have certain sealing;

Panel 4 is corresponding flow path groove and moulding, and it combines the back to form the runner of a sealing with inner housing 1, be provided with a plurality of delivery ports 41 on panel 4 equally.

Key of the present utility model is: be formed with several protruding pin 42 at panel 4 rear part edges, corresponding this protruding pin 42 is provided with mating holes 11 on inner housing 1, and places successively between inner housing 1 and the panel 4 from going out the network of rivers 2 and compacting ring 3 clearly.Cooperate shown in Fig. 2,3, during combination, the protruding pin 42 of each of panel 4 is to stretch the protruding pin 42 that utilizes hot melt will stretch out mating holes 11 behind the mating holes 2 that places inner housing 1 to be fused on the inner housing 1, forms inner housing 1 runner with this.When pushing down inner housing 1, on the inner housing 1 two encloses rib 12 and goes out the network of rivers 2 interference fit certainly clearly, form seal cavity, the utility model is to utilize this solid welding mode, in conjunction with this hermetically-sealed construction, overcome sealing and strength problem between the shaped flow channel, reduce the manufacture difficulty of product and the validity of raising structure greatly.This kind structure can effectively avoid inner housing 1 to occur in conjunction with not firm and phenomenon that occur leaking, thereby improves the bond strength and the bond quality of seedpod of the lotus inner housing, and easily row is simplified in order processing more.

Claims

1, a kind of shower nozzle inner housing welding fixed structure, it is mainly by inner housing, constitute from going out the network of rivers, compacting ring and panel clearly, from go out the network of rivers clearly, compacting ring places between inner housing and the panel, it is characterized in that: be formed with several protruding pin in panel rear, corresponding this protruding pin is provided with mating holes on inner housing, and compacting ring is to place between inner housing and the panel, and the protruding pin of each of panel is to stretch the protruding pin that utilizes hot melt will stretch out mating holes behind the mating holes that places inner housing to be fused on the inner housing.
