Description

Technical Field

[0001] The utility model relates to the field of spraying, in particular to a continuous spraying pressing head. Background Art

[0002] Sprayers are widely used in everyday applications, such as perfumes and medicinal sprays. They are devices that increase the pressure of liquids or gases to cause them to flow. They are used to move liquids, gases, or other special fluids, essentially performing work on the fluid. A sprayer primarily consists of a bottle and a pressure head, which is activated by pressing the pressure head to spray. Currently, commercially available sprayers for perfumes, moisturizers, and skincare products all release the spray once pressed and cease spraying upon release, failing to achieve continuous spraying. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a continuous spray pressing head which has a simple structure, is reliable in use and can spray continuously.

The extrusion seat is vertically movably arranged in the extrusion cavity, and the extrusion seat is sealed with the pressing cap. The extrusion spring is used to drive the extrusion seat to compress the extrusion cavity when the pressing cap is reset, so that the fluid medium in the cavity is continuously ejected outward.

[0009] Preferably, the pressing assembly includes a fixing seat, a pressing tube and a valve assembly, an accommodating cavity is provided inside the fixing seat, and the fixing seat is fixedly matched with the head cap body, one end of the pressing tube is movably passed through the fixing seat and is connected with the extrusion cavity, and the pressing tube is matched with the valve assembly to pump the fluid medium into the extrusion cavity along the pressing tube; the advantage is that the fluid medium can be reliably pumped into the extrusion cavity through the matching of the fixing seat, the pressing tube and the valve assembly, thereby ensuring the reliability of the spraying when the pressing cap is pressed.

[0010] Furthermore, the pressing cap is provided with a fixed tube, which is sealed and fixedly matched with the pressing tube, and the nozzle is provided with a nozzle connected to the fixed tube. The nozzle has a connecting hole, and the connecting hole is used to connect the nozzle and the extrusion chamber; the advantage is that the connection between the nozzle and the extrusion chamber is guaranteed by the connecting hole, thereby ensuring that after the cavity of the extrusion chamber is squeezed, the fluid medium can enter the nozzle from the connecting hole and then be sprayed out from the nozzle.

[0012] Furthermore, the movable seat is provided with a boss, the pressing tube is provided with a pressure platform located above the boss and cooperating with it, the lower part of the pressing tube is provided with a pressure rod, and the sealing seat movable sleeve is provided on the outside of the pressure rod; the advantage is that the cooperation between the provided boss and the pressure platform can reliably ensure that the pressing tube presses the movable seat when moving downward, thereby ensuring that the fluid medium is reliably pumped upward.

[0013] Furthermore, the movable seat is provided with a sealing column which is sleeved on the outside of the pressing tube, the sealing column is provided with an inclined first sealing surface, and the sealing seat is provided with a conical sealing groove which cooperates with the first sealing surface, and the first sealing surface can fit with the conical sealing groove; the advantage is that the cooperation between the first sealing surface and the conical sealing groove can reliably seal the through hole during the rebound process of the pressing cap, thereby ensuring that the fluid medium in the bottle body is reliably sucked into the accommodating cavity below the movable seat.

[0014] Preferably, one end of the extrusion spring is tightly pressed against the extrusion seat, and the other end of the extrusion spring can be pressed against the pressing cap or the head cap body; the advantage is that the extrusion spring can press the extrusion seat upward during the rebound process after the pressing cap is released, thereby reducing the space of the extrusion chamber and realizing continuous ejection of the fluid.

[0015] Furthermore, when the extrusion spring is against the head cap body, the extrusion seat is provided with a limiting groove, and the head cap body is provided with an upwardly protruding fixed column. One end of the extrusion spring is embedded in the limiting groove, and the other end is sleeved on the outside of the fixed column.

[0018] Compared with the existing technology, the present invention has the following advantages: the provided pressing assembly ensures that the fluid medium in the bottle body is reliably pumped into the extrusion chamber when the user presses the press cap, and is then ejected outwards as the press is pressed. At the same time, as the press cap is pressed, the fluid medium pumped into the extrusion chamber drives the extrusion member to move downward, expanding the extrusion chamber. When the press cap is released upwards, the compression spring drives the extrusion member to compress the extrusion chamber, causing the fluid medium inside to be ejected outwards from the nozzle, thereby achieving continuous spraying.

The provided pressing assembly ensures that when the user presses the push cap 2, the fluid medium in the bottle is reliably pumped into the extrusion chamber 2.1 and ejected outwards as the press is applied. Simultaneously, as the push cap 2 is pressed, the fluid medium pumped into the extrusion chamber 2.1 drives the extrusion element downward to expand the extrusion chamber 2.1. As the push cap 2 is released upwards, the compression spring 6.2 drives the extrusion element to compress the extrusion chamber 2.1, causing the fluid medium inside to eject outwards from the nozzle 2.3, thus achieving continuous spraying.

[0031] On the basis of the above, the pressing assembly includes a fixed seat 3, a pressing tube 4 and a valve assembly 5. A accommodating chamber 3.1 is provided inside the fixed seat 3, and the fixed seat 3 is fixedly matched with the head cap body 1. One end of the pressing tube 4 is movable through the fixed seat 3 and is connected to the extrusion chamber 2.1.
