Description

Quantitative pressing spray head and container with quantitative pressing spray head

technical field

The utility model 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

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 the nozzle of the pressure head; loosen the pressure on the pressure head, and the pressure head resets upwards under the force of the spring, at this time, the pipe body is isolated from the cylinder, and the material inlet at the bottom of the cylinder is opened, and the pressure in the cylinder Less than the pressure in the container bottle, the material liquid in the container bottle is sucked into the cylinder so that the cylinder is refilled with material liquid. This structure is not only convenient to use, but also can effectively reduce the waste of solution, so it is widely used. But it also has certain disadvantages:

1. The spring supporting the indenter has a relatively strong spring force, and it takes a lot of effort for the user to depress the indenter, especially for the elderly and children.

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. Repeated liquid spraying brings the problem of inconvenient 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 handle it becomes an urgent problem to be solved.

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

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.

5. The material liquid in the container bottle has the risk of being polluted by the metal elements in the indenter.
