Description

A kind of liquid automatic-closing valve

Technical field

The utility model relates to liquid output mouth, is specifically related to a kind of transfusion mouth that is equipped with on the emulsion container that is installed in.

Background technique

Improving constantly of Along with people's living standard, fluid valve are especially washed daily cosmetics, individual and are protected in the articles for use in the middle of the daily life being used for widely.

The liquid valve gate open often is mounted in daily cosmetics is housed, the individual washes on the container that protects usefulness, and during use, pressing button can be realized the output of emulsion.Existing fluid valve components is more, and structure is comparatively complicated, makes daily cosmetics and individual wash to protect articles for use to have higher cost of production.

The model utility content

To the deficiency of existing technology, the purpose of the utility model is intended to provide a kind of liquid automatic-closing valve, and it is simple in structure, reduces daily cosmetics and the individual cost of production that protects articles for use of washing.

For realizing above-mentioned purpose, the utility model adopts following technological scheme:

A kind of liquid automatic-closing valve; Comprise the mounting pipe that is connected with the emulsion container, the output tube that is connected the mounting pipe outer end; The tube chamber conducting of the tube chamber of mounting pipe and output tube, in the upper end portion of output tube opening sealing an elastic button is installed, the below of elastic button is connected with a spool; This spool can along the length direction of output tube slide and with the airtight applying of the inwall of output tube, the position that output tube is communicated with the mounting pipe output terminal is between elastic button and spool.

Be connected with a connecting rod between elastic button and the spool, the upper end portion of connecting rod is connected the internal surface neutral position of elastic button.

Elastic button is the hemisphere shelly, and the upper end portion opening of output tube is provided with the groove that supplies the elasticity button lip to insert.

Spool is tubaeform that Open Side Down.

The axis of output tube and the axis normal of mounting pipe.

The beneficial effect of the utility model is:

The utility model is simple in structure, only needs less component just can realize the output of emulsion in the container, has reduced daily cosmetics and the individual cost of production that protects articles for use of washing.

Description of drawings

Fig. 1 is the structural representation of a kind of liquid automatic-closing valve of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the user mode schematic representation of liquid automatic-closing valve shown in Figure 1.

Embodiment

Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing:

Like Fig. 1, shown in 2, be a kind of liquid automatic-closing valve of the utility model, it comprises mounting pipe 1, output tube 2; The output terminal of mounting pipe 1 is connected with output tube 2, and the tube chamber of mounting pipe 1 is through the tube chamber conducting of the opening that is provided with on output tube 2 tube walls 22 with output tube 2, and the open upper end of output tube 2 is connected with an elastic button 3; This neutral position, elastic button 3 bottom is connected with a connecting rod 4; The underpart of connecting rod 4 is connected with a spool 5, the airtight applying of inwall of the periphery of spool 5 and output tube 2, and; Spool 5 can slide with respect to output tube 2 along the length direction of output tube 2 under the drive of connecting rod 4.

Opening 22 is between elastic button 3 and spool 5.

Above-mentioned elastic button 3 is the hemisphere shelly; It adopts polythene material to be made, and has certain elasticity, and the open upper end periphery of output tube 2 is provided with groove 21; What the periphery of elastic button 3 was airtight is inlaid in the groove 21, and connecting rod 4 is connected elastic button 3 internal surface intermediate portions.

It is downward opening horn-like that spool 5 is, and adopts nylon material to be made, and guarantees the airtight applying of inwall of its edge and output tube 2.

In addition, the axis normal of the axis of output tube 2 and mounting pipe 1.

As shown in Figure 3, the aforesaid liquid automatic-closing valve is installed in bottom one side of emulsion container, and the internal thread through mounting pipe 1 input end is connected with the emulsion container; And make the tube chamber and the conducting of emulsion container intracavity of mounting pipe 1, when needing the output emulsion, push elastic button 3 downwards; Then elastic button 3 drive spools 5 move downward, and when spool 5 moved to output tube 2 lower ending openings below, the emulsion in output tube 2 tube chambers was exported to the outside; When accomplishing emulsion output, discharge pressure to elastic button 3, then elastic button 3 is because self elastic recoil; Spool 5 is driven to initial position, thereby the lower ending opening of output tube 2 is sealed.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technological scheme and the design of above description.

Claims (5)
