Quantitative pressing spray nozzle and container with quantitative pressing spray nozzle

Abstract

The present invention provides a quantitative pressing spray head, comprising: a pressure plate, a pressure head and a portable screw cap for connecting with a container; On the pressure head; one end of the pressure plate is a fixed end connected with the portable screw cap, and the other end is a pressing end. The pressure plate uses the fixed end as a lever fulcrum to link with the pressure head. The end and the fixed end form a first force arm, the indenter and the fixed end form a second force arm, and the first force arm is greater than the second force arm. The present invention adopts the principle of levers, and under the condition of equal reaction moments, the longer the force arm, the smaller the required force. The present invention uses the fixed end of the pressing plate and the portable screw cap as the fulcrum and the pressing plate as the lever, and reduces the force required to press the pressing head by increasing the distance between the pressing end and the fixed end.

Description

technical field [0001] The invention relates to the technical field of spray heads, in particular to a quantitative pressing spray head and a container with the quantitative pressing spray head. Background technique [0002] Many of the daily necessities that people usually use are equipped with pneumatic nozzles, whose main function is to use the principle of air pressure to extract the liquid in the container through the pipe body. For example, most of the nozzles arranged on containers such as shower gel and hand sanitizer adopt the extraction method of this air pressure pipe body. When it is in use, press the pressure head on the pipe body with your hands, and the piston will compress the material liquid in the cylinder under the force of the pressure head. At this time, the pipe body is connected with the cylinder, and the material inlet at the bottom of the cylinder is closed, and the liquid in the cylinder is compressed into the pipe body, and then spray out through ...

AI Technical Summary

Problems solved by technology

[0003] 1. The spring that supports the indenter is relatively strong, and it takes a lot of effort for the user to depress the indenter, especially for the elderly and children.

[0004] 2. When the amount of material liquid used is large, such as a large amount of laundry detergent used at one time, because the existing nozzle discharge volume is insufficient, it must be pressed several times to achieve the required amount, and it is often necessary to use a measuring cup to measure the accurate spray amount. Multiple sprays bring inconvenience to use

In addition, if it is necessary to achieve quantitative spraying, it is necessary to use a spray head with a large discharge volume, and to match a bottle and cylinder with a large discharge volume. The volume of the bottle becomes larger and heavier, and how to make it easy to hold has become an urgent problem to be solved.

[0005] 3. In the prior art, the piston tends to deviate in the horizontal direction during the pressing down process of the pressure head, which reduces the air tightness of the pressure head cylinder, and even easily causes the problem of the pressure head detachment and rupture when the container falls from a high place

[0006] 4. In the prior art, when the material liquid in the container is too little, the suction pipe of the nozzle cannot fully absorb the material liquid

[0007] 5. The material liquid in the container bottle has the risk of being polluted by the metal elements in the pressure head
