Pressing the pump head is a common form of product packaging, which generates a certain amount of pressure when squeezed outward, so it is easy to cause squeezing and leakage. To avoid unnecessary waste and inconvenience in use, we need to take some measures to prevent the extrusion of the pump head from flowing out.
Firstly, we can control the squeezing force by adjusting the tightness of the pump head. Generally speaking, the greater the tightness of the pump head, the greater the pressure, which can also easily lead to extrusion flow. We can achieve the effect of adjusting the force by appropriately loosening the pump head and adjusting the tightness of the pump head. This not only reduces the squeezing force, but also makes it more convenient to use.
Secondly, we can also install a valve to avoid squeezing and flowing out. This type of valve is connected to a small hole at the outlet of the pump head, which is closed when the pump head is not pressed, and only opens when the pump head is pressed. This can effectively avoid the problem of squeezing and flowing out, while also making it more convenient to control the flow rate of the liquid.
Finally, special sealing structures can also be used to avoid extrusion and leakage. This structure typically uses a flexible material, such as rubber or silicone, to wrap around the outlet of the pump head. When there is no pressure, this softer material can naturally seal the outlet and only open under pressure. The biggest advantage of this structure is that it can effectively avoid squeezing and flowing out, and it is also very convenient to use.
