Description

Technical Field

[0001] The utility model relates to the field of quantity control devices, in particular to an accurate quantity control device suitable for bottled iodine tincture. Background Art

[0002] Iodine tincture is a medical disinfectant, which is usually carried in a carrying bottle. When using iodine tincture, the flat bottle cap of the iodine tincture bottle is usually removed by twisting it, and the iodine tincture in the iodine tincture bottle can be directly poured out.

[0003] In order to facilitate the control of the amount of iodine poured out of the iodine tincture bottle, a pressing pump head will be threadedly connected to the iodine tincture bottle. The pressing pump head mainly includes components such as a pump body, a piston, a valve and a pipeline connection. When the pressing pump head is pressed, the piston in the pump body moves downward, increasing the volume inside the pump body. At the same time, the suction valve opens. Because the pressure inside the pump body is reduced, the liquid enters the pump body from the container or pipeline.

[0004] However, pressing the pump head once will discharge the iodine tincture discharged by pressing the pump head once. However, when squeezing the iodine tincture onto a cotton swab or disinfectant cotton, the required amount is less than the amount discharged by squeezing the pump head once, which will result in the discharge of excess iodine tincture, causing a waste of iodine tincture. It is inconvenient to control the iodine tincture discharged by squeezing the pump head according to usage requirements. Utility Model Content
